Purpose: To assess the magnitude and predictors of patient-reported fatigue among breast cancer patients receiving radiation therapy (RT). Methods and Materials: Patients receiving breast RT completed a survey querying fatigue at each weekly on-treatment visit. Patient-reported fatigue severity and interference was assessed on an ordinal scale of 0 to 4, using a validated scoring system. Baseline anxiety and depression scores were also obtained. The kinetics of mean fatigue scores per week and the maximum fatigue scores over the course of the entire treatment were assessed, and clinical predictors were identified by univariate and multivariate regression. Results: The average fatigue severitymore » and interference scores were 0.6 and 0.46. The average fatigue scores increased to an equivalent extent from week to week, with expected increases of 0.99 in fatigue severity and 0.85 in interference over 7 weeks. Patients treated with hypofractionated RT (HF-RT) versus conventionally fractionated RT (CF-RT) had significantly fewer maximum fatigue severity or interference scores that were >2 (ie, severe or very severe; 29% vs 10% for severity, and 26% vs 8% for interference, P<.01). Age ≤45 years, presence of psychiatric/pain-related comorbidities, and baseline sadness and anxiety severity were predictive of average and maximum fatigue scores (P<.05), but variables related to treatment intensity (eg, mastectomy vs lumpectomy, chemotherapy use, radiation target volumes) and other host factors (working, children, marital status, proximity to RT facility) were not. Conclusion: Patient-reported fatigue modestly increases over RT courses, with less maximum fatigue reported with HF-RT. Younger age and baseline sadness, anxiety, and psychiatric/pain-related comorbidities are powerful predictors of fatigue, whereas other factors, such as treatment intensity, are not. Future studies will investigate interventions for patients at high risk for fatigue.« less

The aim of this study was to assess the impact of radiotherapy (RT) on psychological, financial, and sexual aspects in postmastectomy carcinoma breast patients affecting their quality of life (QOL) before, during, and after RT with a strong emphasis on their management and rehabilitation aspects. A cross-sectional study carried out in a specialized institution, comprising sixty women. Two standardized questionnaires European Organization for Research and Treatment of Cancer (EORTC) 30-item Quality of Life Questionnaire and Quality of Life Questionnaire breast cancer-23 (QLQ-BR23) for health-related quality, translated and validated for the Hindi language were used. The scores' manual of the EORTC was used to calculate the domain scores of the questionnaires. According to the first questionnaire, the emotional function was most affected even at onset of RT treatment and it was worst at the completion of RT treatment with a mean score of 63.75. The global QOL score was also worst at the end of radiation treatment with a mean score of 32.36, while the score 3 months after completion of treatment was 68.16. The symptoms with the highest scores were insomnia with a worst scoring at completion of treatment (29.99), fatigue (26.57), and pain (23.05). According to the QLQ-BR23, the mean score for side effects such as sexual functioning was minimum 0.55 at the completion of RT, which improved to 11.66 on the first follow-up after 3 months. Mean future perspective score which was 57.22 before the start of RT which was reduced to 50.55 at completion, which means that many women experience side effects of RT and impaired sexual satisfaction. Women with breast cancer showed changes in the following domains: financial, emotional, sexual satisfaction, and future prospects. The most frequently mentioned symptoms were fatigue, insomnia, and pain.

To assess long-term quality of life in surviving patients with advanced laryngeal cancer. A follow-up long-term quality-of-life survey of patients randomized to the Veterans Affairs Laryngeal Cancer Study No. 268 on induction chemotherapy and radiation (CT + RT) vs surgery and RT. Forty-six (71%) of the 65 surviving patients with prior stage III or IV laryngeal cancer who could be contacted completed the survey: 25 from the surgery and RT group and 21 from the CT + RT group. Baseline demographic and clinical characteristics among survey respondents were similar, except that those in the CT + RT group were significantly older (mean, 61.2 years) than those in the surgery and RT group (mean, 55.7 years; P<.05). Patients completed the University of Michigan Head and Neck Quality of Life (HNQOL) instrument, the Medical Outcomes Studies Short-Form 36 (SF-36) general health survey, the Beck Depression Inventory as well as smoking and alcohol consumption surveys. Patients randomized to the CT + RT group had significantly better (P<.05) quality-of-life scores on the SF-36 mental health domain (76.0) than the surgery and RT group (63.0), and also had better HNQOL pain scores (81.3 vs 64.3). Compared with patients who underwent laryngectomy, patients with intact larynges (CT + RT with larynx) had significantly less bodily pain (88.5 vs 56.5), better scores on the SF-36 mental health (79.8 vs 64.7), and better HNQOL emotion (89.7 vs 79.4) scores. More patients in the surgery and RT group (28%) were depressed than in the CT + RT group (15%). Better quality-of-life scores in the CT + RT groups appear to be related to more freedom from pain, better emotional well-being, and lower levels of depression than to preservation of speech function.

Purpose: Postorchiectomy adjuvant radiotherapy (RT) for Stage I seminoma can be associated with long-term toxicity, and management strategies with a lower treatment burden achieve the same excellent cure rate. Because studies suggest that radiation oncologists in the United States continue to recommend RT for these patients, we sought to identify factors associated with management recommendations. Methods and Materials: We conducted a one-time internet-based survey among 491 randomly selected American radiation oncologists self-described as specializing in genitourinary oncology. Results: Response rate was 53% (n = 261). Forty-nine percent of respondents worked in university-affiliated practices. Sixty-two percent of respondents always/usually recommended adjuvantmore » RT for patients with Stage I seminoma, whereas 21% always/usually recommended surveillance and 3% always/usually recommended chemotherapy. One third (33%) expressed concerns that patients who experienced relapse during surveillance could not be salvaged. Although 88% of physicians were aware of an increased risk of second malignant neoplasms (SMN) after adjuvant RT, 85% underestimated its magnitude. Compared with physicians not typically recommending RT, physicians who always/usually recommended RT were more likely to believe that patients might not be salvaged at relapse during surveillance (p = 0.008) and were less aware of the association between RT and SMN (p = 0.04). Conclusions: Respondents who always/usually recommend postorchiectomy RT for patients with Stage I seminoma are more likely to underestimate late RT morbidity and to believe that surveillance is associated with increased mortality. Given the equivalent efficacy and reduced morbidity of surveillance compared with RT, our findings underscore the need for ongoing physician education to increase appropriate clinical implementation of surveillance strategies.« less

IHC and FISH are used for categorizing HER 2 status in breast cancer at the protein and DNA level, respectively. HER 2 expression at the RNA level is quantitative, cheaper, easier to standardize and free from interobserver variation. 115 consecutive patients were tested by IHC, FISH and RT-PCR (test cohort). Assuming FISH result to be the response variable, ROC curves for RT-PCR ratio were analyzed to label HER 2 negative, equivocal and positive cases as RT-PCR score 1, 2 and 3, respectively. Inter-relationships between RT-PCR, IHC and FISH were defined. 'Clinical benefit' of a test was defined as proportion of patients labeled unequivocally as HER 2 positive or negative. Population for 1 year was simulated constraint to previous reports of HER 2 positivity and IHC category distribution by a meta-analysis of previous studies that evaluated concordance between IHC and FISH to determine HER 2 status (simulation cohort). Four diagnostic pathways in the simulation cohort were defined-(1) initial IHC, followed by FISH (conventional pathway); (2) initial RT-PCR, followed by FISH; (3) initial IHC, followed by RT-PCR and then by FISH; (4) initial RT-PCR, followed by IHC and then by FISH. The clinical benefit of IHC and RT-PCR in the four pathways was analyzed and sensitivity analysis for incremental cost-effectiveness ratio and cost-benefit comapring RT-PCR against IHC, both as first-line tests and among those with IHC score 2 as a reflex second-line test was performed by the Monte Carlo technique. 115 patients comprised the study population. While none with IHC score of 0 or 1 was FISH positive for HER 2, all cases with IHC score of 3 were FISH positive. 43 cases were assigned IHC score of 2. Thus, 72 patients benefited from the initial IHC testing [clinical benefit 62.6%], with the overall concordance between IHC and FISH being 100% for those with IHC score of 0, 1 and 3 (conclusive IHC categories). For RT-PCR with 100% concordance, 15.7% (115-97 = 18) patients would have benefited from RT-PCR testing if it was used as a first-line test. If RT-PCR would have been used as a second-line test among those with IHC score 2 (n = 43), then only 6 patients would have been assigned a conclusive RT-PCR category (category 1 or 3) translating to a clinical benefit of 14% (6/43) as a second-line test. As a second-line test it had 51% probability to prove more cost-effective than the conventional pathway, provided the cost of RT-PCR was 0.4 times the cost of IHC. Also in a three-step pathway, RT-PCR upfront would have 56% probability of higher cost-benefit provided the cost of RT-PCR was 0.1 times the cost of IHC. RT-PCR results were found to be suboptimal to IHC in terms of discriminative ability and clinical benefit; thus, it is unlikely to replace IHC as a first-line test in the near future.

Globally, morbidity and mortality due to cancer are predicted to increase in both men and women in the coming decades. Furthermore, it is estimated that two thirds of these cancer-related deaths will occur in low-and middle-income countries (LMIC). In addition to morbidity and mortality, cancer also causes an enormous economic burden, especially in developing countries. There are several treatment and management options for cancer including chemotherapy, radiation therapy, surgery, and palliative care. Radiotherapy or radiation therapy (RT) can be an effective treatment, especially for localized or solid cancers; about half of cancer patients receive radiation as a curative or palliative treatment. Because of its low cost, for patients from LMIC with inoperable tumors, RT may be the only option. With the overall increase in the number of cancer patients especially in resource-starved LMIC, the need for more RT facilities further affects the economic growth of those countries. Therefore, an advanced molecular-targeted and more integrated approach involving either RT alone or with surgery and improved cancer drug access worldwide are urgent needs for cancer care.

Purpose: To evaluate the effects of radiation therapy (RT) on neurocognitive function in patients with nasopharyngeal carcinoma (NPC). Methods and Materials: Thirty patients with NPC treated with intensity-modulated RT were included. Dose-volume histograms of the temporal lobes were obtained in every patient. Neurocognitive tests were administered individually to each patient 1 day before initiation of RT and at least 12 months after completion of RT. Cognitive functioning status was evaluated as change in scores over time. Results: Among the total of 30 patients, 23 patients (76.7%) had significantly lower post-RT cognitive functioning scores compared with their pre-RT scores (p =more » 0.033). The cognitive functioning scores had significantly declined in the domains of short-term memory, language abilities, and list-generating fluency (p = 0.020, 0.023, and 0.001, respectively). Compared with patients with a mean dose to the temporal lobes of 36 Gy or less, patients with a mean dose of greater than 36 Gy had a significantly greater reduction in cognitive functioning scores (p = 0.017). Patients in whom V60 of the temporal lobes (i.e., the percentage of the temporal lobe volume that had received >60 Gy) was greater than 10% also had a greater reduction in cognitive functioning scores than those in whom V60 was 10% or less (p = 0.039). Conclusions: The results of our study indicated that RT could have deleterious effects on cognitive function in patients with NPC. Efforts should be made to reduce the radiation dose and irradiated volume of temporal lobes without compromising the coverage of target volume.« less

Background To assess acute (primary endpoint) and late toxicity, quality of life (QOL), biochemical or clinical failure (secondary endpoints) of a hypofractionated IMRT schedule for prostate cancer (PC). Methods 38 men with localized PC received 66 Gy (2.64 Gy) to prostate,2 Gy to seminal vesicles (50 Gy total) using IMRT. Acute toxicity was evaluated weekly during radiotherapy (RT), at 1–3 months afterwards using RTOG acute scoring system. Late side effects were scored at 6, 9, 12, 16, 20, 24 and 36 months after RT using RTOG/EORTC criteria. Quality of life was assessed by EORTC-C30 questionnaire and PR25 prostate module. Biochemical failure was defined using ASTRO consensus and nadir+2 definition, clinical failure as local, regional or distant relapse. Results None experienced grade III-IV toxicity. 10% had no acute genito-urinary (GU) toxicity, 63% grade I; 26% grade II. Maximum acute gastrointestinal (GI) scores 0, I, II were 37%, 47% and 16%. Maximal acute toxicity was reached weeks 4–5 and resolved within 4 weeks after RT in 82%. Grade II rectal bleeding needing coagulation had a peak incidence of 18% at 16 months after RT but is 0% at 24–36 months. One developed a urethral stricture at 2 years (grade II late GU toxicity) successfully dilated until now. QOL urinary symptom scores reached a peak incidence 1 month after RT but normalized 6 months later. Bowel symptom scores before, at 1–6 months showed similar values but rose slowly 2–3 years after RT. Nadir of sexual symptom scores was reached 1–6 months after RT but improved 2–3 years later as well as physical, cognitive and role functional scales. Emotional, social functional scales were lowest before RT when diagnosis was given but improved later. Two years after RT global health status normalized. Conclusion This hypofractionated IMRT schedule for PC using 25 fractions of 2.64 Gy did not result in severe acute side effects. Until now late urethral, rectal toxicities seemed acceptable as well as failure rates. Detailed analysis of QOL questionnaires resulted in the same conclusion. PMID:17686162

Acquired immunodeficiency syndrome caused by human immunodeficiency virus (HIV) is an immunosuppressive disease. Over the past decades, it has plagued human health due to the grave consequences in its harness. For this reason, anti-HIV agents are imperative, and the search for the same from natural resources would assure the safety. In this investigation we have performed molecular docking, molecular property prediction, drug-likeness score, and molecular dynamics (MD) simulation to develop a novel anti-HIV drug. We have screened 12 alkaloids from a medicinal plant Toddalia asiatica for its probabilistic binding with the active site of the HIV-1-reverse transcriptase (HIV-1-RT) domain (the major contributor to the onset of the disease). The docking results were evaluated based on free energies of binding (ΔG), and the results suggested toddanol, toddanone, and toddalenone to be potent inhibitors of HIV-1-RT. In addition, the alkaloids were subjected to molecular property prediction analysis. Toddanol and toddanone with more rotatable bonds were found to have a drug-likeness score of 0.23 and 0.11, respectively. These scores were comparable with the standard anti-HIV drug zidovudine with a model score 0.28. Finally, two characteristic protein-ligand complexes were exposed to MD simulation to determine the stability of the predicted conformations. The toddanol-RT complex showed higher stability and stronger H-bonds than toddanone-RT complex. Based on these observations, we firmly believe that the alkaloid toddanol could aid in efficient HIV-1 drug discovery. In the present study, the molecular docking and MD simulations are performed to explore the possible binding mode of HIV 1 RT with 12 alkaloids of T. asiatica. Molecular docking by AutoDock4 revealed three alkaloids toddanol, toddanone, and toddalenone with highest binding affinity towards HIV 1 RT. The drug likeness model score revealed a positive score for toddanol and toddanone which is comparable to the drug likeness score of the standard anti HIV drug zidovudine. Results from simulation analysis revealed that toddanol RT complex is more stable than toddanone RT complex inferring toddanol as a potential anti HIV drug molecule.

Childhood craniopharyngioma is a complex condition to manage. Survival figures are high but the potential for long-term morbidity is great. There is much debate regarding the best management for these tumours with increasing interest in the use of proton beam therapy. We have therefore reviewed our radiotherapy (RT) practice at Westmead Hospital and the literature regarding the use of protons for these children. Three children have received fractionated stereotactic RT for craniopharyngioma at Westmead Hospital since 2007. Each RT plan was reviewed and additional organs at risk were contoured to enable comparison with published proton data. Planning target volume coverage was similar with all modalities: with the conformity index ranging from 0.70 to 0.78 in our patients compared with 0.50-0.84 in the published data. RT dose to temporal lobes, hippocampi and whole brain was also similar with protons and photons. Proton beam therapy may give lower dose to the Circle of Willis than stereotactic RT. Currently there is no clear evidence that proton beam therapy will improve survival or reduce morbidity for children with craniopharyngioma. However, proton therapy has the potential to reduce RT dose to the Circle of Willis, which may reduce the risk of future cerebrovascular complications. We propose that more resources should be allocated to ensuring these patients are managed by experienced multidisciplinary teams through the continuum from diagnosis to long-term follow-up. © 2014 The Royal Australian and New Zealand College of Radiologists.

Introduction Preservation of kidney and renal function is the goal of nonoperative management (NOM) of renal trauma (RT). The advantages of NOM for minor blunt RT have already been clearly described, but its value for major blunt and penetrating RT is still under debate. We present a systematic review and meta-analysis on NOM for RT, which was compared with the operative management (OM) with respect to mortality, morbidity, and length of hospital stay (LOS). Methods The Preferred Reporting Items for Systematic Reviews and Meta-analyses statement was followed for this study. A systematic search was performed on Embase, Medline, Cochrane, and PubMed for studies published up to December 2015, without language restrictions, which compared NOM versus OM for renal injuries. Results Twenty nonrandomized retrospective cohort studies comprising 13,824 patients with blunt (2,998) or penetrating (10,826) RT were identified. When all RT were considered (American Association for the Surgery of Trauma grades 1–5), NOM was associated with lower mortality and morbidity rates compared to OM (8.3% vs 17.1%, odds ratio [OR] 0.471; 95% confidence interval [CI] 0.404–0.548; P<0.001 and 2% vs 53.3%, OR 0.0484; 95% CI 0.0279–0.0839, P<0.001). Likewise, NOM represented the gold standard treatment resulting in a lower mortality rate compared to OM even when only high-grade RT was considered (9.1% vs 17.9%, OR 0.332; 95% CI 0.155–0.708; P=0.004), be they blunt (4.1% vs 8.1%, OR 0.275; 95% CI 0.0957–0.788; P=0.016) or penetrating (9.1% vs 18.1%, OR 0.468; 95% CI 0.398–0.0552; P<0.001). Conclusion Our meta-analysis demonstrated that NOM for RT is the treatment of choice not only for AAST grades 1 and 2, but also for higher grade blunt and penetrating RT. PMID:28894376

Purpose: To investigate the feasibility of ultrasound Nakagami imaging to quantitatively assess radiation-induced neck fibrosis, a common sequela of radiation therapy (RT) to the head and neck. Methods and Materials: In a pilot study, 40 study participants were enrolled and classified into 3 subgroups: (1) a control group of 12 healthy volunteers; (2) an asymptomatic group of 11 patients who had received intensity modulated RT for head and neck cancer and had experienced no neck fibrosis; and (3) a symptomatic group of 17 post-RT patients with neck fibrosis. Each study participant underwent 1 ultrasound study in which scans were performedmore » in the longitudinal orientation of the bilateral neck. Three Nakagami parameters were calculated to quantify radiation-induced tissue injury: Nakagami probability distribution function, shape, and scaling parameters. Physician-based assessments of the neck fibrosis were performed according to the Radiation Therapy Oncology Group late morbidity scoring scheme, and patient-based fibrosis assessments were rated based on symptoms such as pain and stiffness. Results: Major discrepancies existed between physician-based and patient-based assessments of radiation-induced fibrosis. Significant differences in all Nakagami parameters were observed between the control group and 2 post-RT groups. Moreover, significant differences in Nakagami shape and scaling parameters were observed among asymptomatic and symptomatic groups. Compared with the control group, the average Nakagami shape parameter value increased by 32.1% (P<.001), and the average Nakagami scaling parameter increased by 55.7% (P<.001) for the asymptomatic group, whereas the Nakagami shape parameter increased by 74.1% (P<.001) and the Nakagami scaling parameter increased by 83.5% (P<.001) for the symptomatic group. Conclusions: Ultrasonic Nakagami imaging is a potential quantitative tool to characterize radiation-induced asymptomatic and symptomatic neck fibrosis.« less

The major complications of peptic ulcer are hemorrhage, perforation and gastric outlet obstruction with perforation occurring in about 2-10% of patients. Patients with perforated peptic ulcer still have a high rate of morbidity and mortality and to improve the outcomes it is important to stratify the patients into different categories. To evaluate the accuracy of Boey scoring system in predicting postoperative morbidity and mortality in patients operated for peptic perforation. It was a prospective observational single centre study conducted at SMS Medical College and Hospital, Jaipur, from October 2011 to October 2012 on 180 patients undergoing open surgery for peptic ulcer perforation. Postoperative outcomes in terms of recovery and complications were studied. For prediction of morbidity and mortality by Boey risk stratification, the odds ratio (OR) and 95% confidence interval (95% CI) of each risk score were compared with the outcomes of "0" risk score. The mortality rate increased progressively with increasing numbers of the Boey score: 1.9%, 7.1%, 31.7% and 40% for 0, 1, 2, and 3 scores, respectively (p < 0.001). The morbidity rates for 0, 1, 2, and 3 Boey scores were 13%, 45.7%, 70.7% and 73.3% respectively (p < 0.001). Boey score is a useful tool for assessing the prognosis of operated cases of peptic perforation and helps in the assessment of mortality and morbidity of these patients.

Purpose: Level I evidence demonstrates equivalent pain response after single-fraction (SF) or multifraction (MF) radiation therapy (RT) for bone metastases. The purpose of this study is to provide additional data to inform the incidence and predictors of adverse outcomes after RT for spine metastases. Methods and Materials: At a single institution, 299 uncomplicated spine metastases (without cord compression, prior RT, or surgery) treated with RT from 2008 to 2013 were retrospectively reviewed. The spinal instability neoplastic score (SINS) was used to assess spinal instability. The primary outcome was time to first spinal adverse event (SAE) at the site, including symptomaticmore » vertebral fracture, hospitalization for site-related pain, salvage surgery, interventional procedure, new neurologic symptoms, or cord compression. Fine and Gray's multivariable model assessed associations of the primary outcome with SINS, SF RT, and other significant baseline factors. Propensity score matched analysis further assessed the relationship of SF RT to first SAEs. Results: The cumulative incidence of first SAE after SF RT (n=66) was 6.8% at 30 days, 16.9% at 90 days, and 23.6% at 180 days. For MF RT (n=233), the incidence was 3.5%, 6.4%, and 9.2%, respectively. In multivariable analysis, SF RT (hazard ratio [HR] = 2.8, 95% confidence interval [CI] 1.5-5.2, P=.001) and SINS ≥11 (HR=2.5 , 95% CI 1.3-4.9, P=.007) were predictors of the incidence of first SAE. In propensity score matched analysis, first SAEs had developed in 22% of patients with SF RT versus 6% of those with MF RT cases (HR=3.9, 95% CI 1.6-9.6, P=.003) at 90 days after RT. Conclusion: In uncomplicated spinal metastases treated with RT alone, spinal instability with SINS ≥11 and SF RT were associated with a higher rate of SAEs.« less

To assess long-term xerostomia in patients receiving parotid-sparing radiation therapy (RT) for head-and-neck cancer, and to find the patient and therapy-related factors that affect its severity. From March 1994 through January 2000, 84 patients received comprehensive bilateral neck RT using conformal and multisegmental intensity-modulated RT (IMRT) aiming to spare the major salivary glands. Before RT and periodically through 2 years after the completion of RT, salivary flow rates from each of the major salivary glands were selectively measured. At the same time intervals, each patient completed an 8-item self-reported xerostomia-specific questionnaire (XQ). To gain a relative measure of the effect of RT on the minor salivary glands, whose output could not be measured, the surfaces of the oral cavity (extending to include the surface of the base of tongue) were outlined in the planning CT scans. The mean doses to the new organ ("oral cavity") were recorded. Forty-eight patients receiving unilateral neck RT were similarly studied and served as a benchmark for comparison. Factors predicting the XQ scores were analyzed using a random-effects model. The XQ was found to be reliable and valid in measuring patient-reported xerostomia. The spared salivary glands which had received moderate doses in the bilateral RT group recovered to their baseline salivary flow rates during the second year after RT, and the spared glands in the unilateral RT group, which had received very low doses, demonstrated increased salivary production beyond their pre-RT levels. The increase in the salivary flow rates during the second year after RT paralleled an improvement in xerostomia in both patient groups. The improvement in xerostomia was faster in the unilateral compared with the bilateral RT group, but the difference narrowed at 2 years. The major salivary gland flow rates had only a weak correlation with the xerostomia scores. Factors found to be independently associated with the xerostomia scores were the pre-RT baseline scores, the time since RT, and the mean doses to the major salivary glands (notably to the submandibular glands) and to the oral cavity. An improvement over time in xerostomia, occurring in tandem with rising salivary production from the spared major salivary glands, suggests a long-term clinical benefit from their sparing. The oral cavity mean dose, representing RT effect on the minor salivary glands, was found to be a significant, independent predictor of xerostomia. Thus, in addition to the major salivary glands, sparing the uninvolved oral cavity should be considered as a planning objective to further reduce xerostomia.

The purpose of this study was to investigate the utility of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system for predicting post-operative morbidity. We included 1,883 patients (mean age, 52.1 years) who underwent orthopaedic surgery. The post-operative complications were classified as surgical site and non-surgical site complications, and the relationship between the E-PASS scores and post-operative morbidity was investigated. The incidence of post-operative complications (n = 274) significantly increased with an increase in E-PASS scores (p < 0.001). The areas under the curve for the comprehensive risk score of the E-PASS scoring system for overall and non-surgical site complications were 0.777 and 0.794, respectively. The E-PASS scoring system showed some utility in predicting post-operative morbidity after general orthopaedic surgery. However, creating a new risk score that is more suitable for orthopaedic surgery will be challenging.

The traditional indications for adjuvant pelvic radiotherapy (RT) for International Federation of Obstetrics and Gynecology (FIGO) stage Ib1 lymph nodes-negative cervix carcinoma following radical surgery based on histopathological factors, such as deep stromal invasion and lymphovascular space invasion (LVSI), were often inconsistently applied. The perceived risk of relapse was subjectively determined. This pilot study attempts to determine if the treatment outcome will be affected when the indication for RT is based on the Gynecologic Oncology Group (GOG) Risk Score (RS) and the field of adjuvant RT is tailored to the RS. From 1997 to 1999, 55 patients with FIGO stage Ib1 lymph nodes-negative cervical carcinoma limited to the cervix were prescribed RT following radical surgery, based on their RS, as follows: RS <40, RT is omitted; RS >40 to <120, modified (smaller) field RT; and RS >120, standard field pelvic RT. Their incidence and site of recurrence were compared with a similar cohort of 40 patients who were treated prior to 1997. Prior to 1997, of the 40 patients, 10 patients were given standard field RT. There were 2 (5%) recurrent diseases. The mean duration of follow-up was 61.6 months (range, 1 to 103 months). The RS of 23 of the 30 patients who were not given RT were available. The mean RS was 22 with 5 patients having a score of >40. From 1997 onwards, of the 55 patients, 28 (51%) did not require RT, 13 (23%) were treated with modified (smaller) field RT and 14 (26%) were given standard field RT. There were 2 (3.6%) cases of relapse. The mean duration of follow-up was 36.4 months (range, 5 to 60 months). All patients with a RS of <40 did not suffer any relapse. Their survival outcomes were better when compared to patients who did not have any RT in the GOG Study. The results of this study indicated that postoperative adjuvant RT given to patients with a high GOG RS of >120, significantly improved their 5-year recurrence rate and disease-free survival, as compared with the similar group of patients who were without adjuvant therapy in the GOG study. Patients with a GOG risk-score of <40 may be safely spared from adjuvant pelvic RT. The current treatment protocol did not compromise the outcome in patients, compared with the use of a less precise treatment protocol in the past.

The heterogeneity of high-grade glioma recurrences remains an ongoing challenge for the interdisciplinary neurooncology team. Response to re-irradiation (re-RT) is heterogeneous, and survival data depend on prognostic factors such as tumor volume, primary histology, age, the possibility of reresection, or time between primary diagnosis and initial RT and re-RT. In the present pooled analysis, we gathered data from radiooncology centers of the DKTK Consortium and used it to validate the established prognostic score by Combs et al. and its modification by Kessel et al. Data consisted of a large independent, multicenter cohort of 565 high-grade glioma patients treated with re-RT from 1997 to 2016 and a median dose of 36 Gy. Primary RT was between 1986 and 2015 with a median dose of 60 Gy. Median age was 54 years; median follow-up was 7.1 months. Median OS after re-RT was 7.5, 9.5, and 13.8 months for WHO IV, III, and I/II gliomas, respectively. All six prognostic factors were tested for their significance on OS. Aside from the time from primary RT to re-RT (P = 0.074) and the reresection status (P = 0.101), all factors (primary histology, age, KPS, and tumor volume) were significant. Both the original and new score showed a highly significant influence on survival with P < 0.001. Both prognostic scores successfully predict survival after re-RT and can easily be applied in the routine clinical workflow. Now, further prognostic features need to be found to even improve treatment decisions regarding neurooncological interventions for recurrent glioma patients. © 2018 The Authors.

The goal of this study was to validate the usefulness of risk assessment scoring systems for a surgical audit in elective digestive surgery for elderly patients. The validated scoring systems used were the Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) and the Portsmouth predictor equation for mortality (P-POSSUM). This study involved 153 consecutive patients aged 75 years and older who underwent elective gastric or colorectal surgery between July 2004 and June 2006. A retrospective analysis was performed on data collected prior to each surgery. The predicted mortality and morbidity risks were calculated using each of the scoring systems and were used to obtain the observed/predicted (O/E) mortality and morbidity ratios. New logistic regression equations for morbidity and mortality were then calculated using the scores from the POSSUM system and applied retrospectively. The O/E ratio for morbidity obtained from POSSUM score was 0.23. The O/E ratios for mortality from the POSSUM score and the P-POSSUM were 0.15 and 0.38, respectively. Utilizing the new equations using scores from the POSSUM, the O/E ratio increased to 0.88. Both the POSSUM and P-POSSUM over-predicted the morbidity and mortality in elective gastrointestinal surgery for malignant tumors in elderly patients. However, if a surgical unit makes appropriate calculations using its own patient series and updates these equations, the POSSUM system can be useful in the risk assessment for surgery in elderly patients.

To compare fear of movement in patients with different body mass index (BMI) values referred for rehabilitative care of the knee and to examine whether this fear contributed to self-reported knee-related function. We hypothesized that fear of movement would be elevated with increasing BMI and that fear would correspond with lower self-report knee-related function and lower quality of life (QOL). Retrospective cross-sectional study. Outpatient therapy clinic affiliated with a tertiary care hospital. Patients with knee pain diagnoses (n = 278) were stratified into 4 BMI groups (in < or =25 kg/m(2) nonobese; 25-29.9 kg/m(2) overweight; 30-39.9 kg/m(2) obese; > or =40 kg/m(2) morbidly obese). The Tampa Scale of Kinesiophobia (TSK; fear of movement), International Knee Documentation (IKDC; knee function), and Short-Form 8 (SF-8; QOL) scores were main outcomes. Pain and straight leg raise test scores also were collected. After review of the medical records, descriptive statistics and nonparametric tests were performed, and TSK, QOL, and SF-8 scores were compared. Hierarchical regression modeling determined the contribution of TSK scores to the variance of IKDC scores. Pain scores were greatest in the nonobese group and lowest in the morbidly obese group (7.5 +/- 2.6 points vs 4.8 +/- 3.1 points; P < .05). TSK scores in morbidly obese patients were greater than in nonobese patients (27.1 +/- 7.7 points vs 22.0 +/- 6.6 points; P = .002). The SF-8 mental-physical subscores were 27% to 32% lower in the morbidly obese than nonobese patients (both P < .0001). IKDC scores were lower in the morbidly obese than nonobese patients (32.1 +/- 19.2 points vs 50.9 +/- 23.8 points; P = .0001). Pain severity and TSK scores contributed 28.6% and 7.1% to the variance of the IKDC scores (overall R(2) = 68.6). Morbid obesity is associated with elevated fear of movement. Pain was the strongest predictor of IKDC scores, and fear of movement enhanced this predictive value of the regression model. Despite lower absolute pain severity in the morbidly obese group, this fear may influence IKDC scores in this population. Morbidly obese patients might benefit from rehabilitation activities that reduce fear of movement to optimize participation in rehabilitation activity.

The three classical Donders' reaction time (RT) tasks (simple, choice, and discriminative RTs) were employed to compare reaction time scores from college students obtained by use of Montare's simplest chronoscope (meterstick) methodology to scores obtained by use of a digital-readout multi-choice reaction timer (machine). Five hypotheses were tested. Simple RT, choice RT, and discriminative RT were faster when obtained by meterstick than by machine. The meterstick method showed higher reliability than the machine method and was less variable. The meterstick method of the simplest chronoscope may help to alleviate the longstanding problems of low reliability and high variability of reaction time performances; while at the same time producing faster performance on Donders' simple, choice and discriminative RT tasks than the machine method.

The purposes of this study were to determine clinical presentations and surgical outcomes of perforated peptic ulcer (PPU), and to evaluate the accuracy of the Boey scoring system in predicting mortality and morbidity. We carried out a retrospective study of patients undergoing emergency surgery for PPU between 2001 and 2006 in a university hospital. Clinical presentations and surgical outcomes were analyzed. Adjusted odds ratio (OR) of each Boey score on morbidity and mortality rate was compared with zero risk score. Receiver-operating characteristic curve analysis was used to compare the predictive ability between Boey score, American Society of Anesthesiologists (ASA) classification, and Mannheim Peritonitis Index (MPI). The study included 152 patients with average age of 52 years (range: 15-88 years), and 78% were male. The most common site of PPU was the prepyloric region (74%). Primary closure and omental graft was the most common procedure performed. Overall mortality rate was 9% and the complication rate was 30%. The mortality rate increased progressively with increasing numbers of the Boey score: 1%, 8% (OR=2.4), 33% (OR=3.5), and 38% (OR=7.7) for 0, 1, 2, and 3 scores, respectively (p<0.001). The morbidity rates for 0, 1, 2, and 3 Boey scores were 11%, 47% (OR=2.9), 75% (OR=4.3), and 77% (OR=4.9), respectively (p<0.001). Boey score and ASA classification appeared to be better than MPI for predicting the poor surgical outcomes. Perforated peptic ulcer is associated with high rates of mortality and morbidity. The Boey risk score serves as a simple and precise predictor for postoperative mortality and morbidity.

Purpose: To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery. Methods and Materials: The records of 17 primary sacral chordoma patients treated since 1990 with surgery (n = 10) or carbon ion RT (n = 7) were retrospectively analyzed for disease-specific survival, local recurrence-free survival, complications, and functional outcome. The applied carbon ion dose ranged from 54.0 Gray equivalent (GyE) to 73.6 GyE (median 70.4). Results: The mean age at treatment was 55 years for the surgery group and 65 years for the carbon ion RT group. The medianmore » duration of follow-up was 76 months for the surgery group and 49 months for the carbon ion RT group. The local recurrence-free survival rate at 5 years was 62.5% for the surgery and 100% for the carbon ion RT group, and the disease-specific survival rate at 5 years was 85.7% and 53.3%, respectively. Urinary-anorectal function worsened in 6 patients (60%) in the surgery group, but it was unchanged in all the patients who had undergone carbon ion RT. Postoperative wound complications requiring reoperation occurred in 3 patients (30%) after surgery and in 1 patient (14%) after carbon ion RT. The functional outcome evaluated using the Musculoskeletal Tumor Society scoring system revealed 55% in the surgery group and 75% in the carbon ion RT group. Of the six factors in this scoring system, the carbon ion RT group had significantly greater scores in emotional acceptance than did the surgery group. Conclusion: Carbon ion RT results in a high local control rate and preservation of urinary-anorectal function compared with surgery.« less

Central and local laboratory concordance for hormone receptor measurement is therapeutically important. This study compares estrogen receptor (ER) and progesterone receptor (PR) measured by local laboratory immunohistochemistry (IHC), central IHC, and central reverse-transcriptase polymerase chain reaction (RT-PCR) using a proprietary 21-gene assay. A case-control sample of 776 breast cancer patients from Eastern Cooperative Oncology Group (ECOG) study E2197 was evaluated. Central IHC Allred score for ER and PR was obtained using tissue microarrays and 1D5 ER antibody and 636 PR antibody. Quantitative RT-PCR for ER and PR in whole sections was performed using the 21-gene assay. For ER, the concordance between local and central IHC was 90% (95% CI, 88% to 92%), between local IHC and central RT-PCR was 91% (95% CI, 89% to 93%), and between central IHC and central RT-PCR was 93% (95% CI, 91% to 95%). For PR, the concordance between local IHC and central IHC was 84% (95% CI, 82% to 87%), between local IHC and central RT-PCR was 88% (95% CI, 85% to 90%), and between central IHC and central RT-PCR was 90% (95% CI, 88% to 92%). Although concordance was high, IHC ER-negative cases that were RT-PCR positive were more common than IHC ER-positive cases that were RT-PCR negative. In ER-positive patients, ER expression by central IHC Allred score was marginally associated with recurrence (P = .091), and ER expression by central RT-PCR was significantly associated with recurrence (P = .014). However, recurrence score, which incorporates additional genes/pathways, was a highly significant predictor of recurrence (P < .0001). There is a high degree of concordance among local IHC, central IHC, and central RT-PCR by the proprietary gene assay for ER and PR status. Although ER expression is marginally associated with relapse in ER-positive patients treated with chemohormonal therapy, recurrence score is a highly significant predictor of recurrence.

To evaluate the diagnostic value of a novel fully automated immunohistochemistry (IHC) assay for detection of anaplastic lymphoma kinase (ALK) fusion in a large number of ALK-positive lung adenocarcinoma (ADC) patients. We tested 196 lung ADCs for ALK rearrangement by two IHC assays (Ventana pre-diluted ALK D5F3 antibody with the Optiview DAB IHC detection kit and Optiview Amplification kit, D5F3 by Cell Signaling Technology (CST) with Ultraview DAB detection kit by Ventana), fluorescence in situ hybridization (FISH) and real-time reverse transcription-PCR (RT-PCR). CST ALK IHC was scored using the scoring scheme of 0, no staining; 1+, faint; 2+, moderate; and 3+, strong cytoplasmic reactivity in ≥ 10% of tumor cells. As for Ventana IHC, a binary scoring system (positive or negative for ALK status) was adopted for evaluating the staining results. Among 196 cases tested, 63 (32%), 65 (33%), 70 (36%), and 69 (35%) cases were ALK positive by FISH, Ventana IHC, CST IHC, and RT-PCR, respectively. The sensitivity and specificity of Ventana IHC were 100% and 98%, respectively. Two Ventana IHC-positive cases, which were also CST IHC score of 3+, showed FISH negative, but their ALK rearrangement was confirmed by RT-PCR and direct sequencing. The sensitivity and specificity of CST IHC with staining intensity score of 1+ or more were 100% and 95%, respectively. Five (25%, of 20) patients with CST IHC score of 1+ were both FISH and RT-PCR negative. The sensitivity and specificity of RT-PCR for detection of ALK fusion were 98% and 95%, respectively. The total accordance rate between ALK RT-PCR and Ventana IHC was 97%. The novel fully automated IHC assay is a reliable screening tool in routine pathologic laboratories for identification of patients with ALK rearrangement for targeted therapy in lung ADC.

Glutaric aciduria type 1 is a rare neurometabolic disease with high morbidity. To describe the MR imaging abnormalities in glutaric aciduria type 1 and to identify any association between the clinical and imaging features. MRI scans of 29 children (mean age: 16.9 months) with confirmed diagnosis of glutaric aciduria type 1 were retrospectively reviewed. Gray matter and white matter scores were calculated based on a previously published pattern-recognition approach of assessing leukoencephalopathies. Hippocampal formation and opercular topography were assessed in relation to the known embryological basis. MRI scores were correlated with morbidity score. The most consistent MRI abnormality was widened operculum with dilatation of the subarachnoid spaces surrounding underdeveloped frontotemporal lobes. Incomplete hippocampal inversion was also seen. The globus pallidus was the most frequently involved gray matter structure (86%). In addition to the central tegmental tract, white matter abnormalities preferentially involved the central and periventricular regions. The morbidity score correlated with the gray matter abnormality score (P = 0.004). Patients with dystonia had higher gray matter and morbidity scores. Morbidity is significantly correlated with abnormality of gray matter, rather than white matter, whether secondary to acute encephalopathic crisis or insidious onset disease.

Radiation Therapy Oncology Group 9402 compared procarbazine, lomustine, and vincristine (PCV) chemotherapy plus radiation therapy (PCV + RT) vs. RT alone for anaplastic oligodendroglioma. Here we report longitudinal changes in cognition and quality of life, effects of patient factors and treatments on cognition, quality of life and survival, and prognostic implications of cognition and quality of life. Cognition was assessed by Mini Mental Status Examination (MMSE) and quality of life by Brain-Quality of Life (B-QOL). Scores were analyzed for survivors and within 5 years of death. Shared parameter models evaluated MMSE/B-QOL with survival. For survivors, MMSE and B-QOL scores were similar longitudinally and between treatments. For those who died, MMSE scores remained stable initially, whereas B-QOL slowly declined; both declined rapidly in the last year of life and similarly between arms. In the aggregate, scores decreased over time (p = 0.0413 for MMSE; p = 0.0016 for B-QOL) and were superior with age <50 years (p < 0.001 for MMSE; p = 0.0554 for B-QOL) and Karnofsky Performance Score (KPS) 80-100 (p < 0.001). Younger age and higher KPS were associated with longer survival. After adjusting for patient factors and drop-out, survival was longer after PCV + RT (HR = 0.66, 95% CI = 0.49-0.9, p = 0.0084; HR = 0.74, 95% CI = 0.54-1.01, p = 0.0592) in models with MMSE and B-QOL. In addition, there were no differences in MMSE and B-QOL scores between arms (p = 0.4752 and p = 0.2767, respectively); higher scores predicted longer survival. MMSE and B-QOL scores held steady in the upper range in both arms for survivors. Younger, fitter patients had better MMSE and B-QOL and longer survival. (c) 2010 Elsevier Inc. All rights reserved.

Using perinatal morbidity scoring tools as a primary study outcome.

Hutcheon, Jennifer A; Bodnar, Lisa M; Platt, Robert W

2017-11-01

Perinatal morbidity scores are tools that score or weight different adverse events according to their relative severity. Perinatal morbidity scores are appealing for maternal-infant health researchers because they provide a way to capture a broad range of adverse events to mother and newborn while recognising that some events are considered more serious than others. However, they have proved difficult to implement as a primary outcome in applied research studies because of challenges in testing if the scores are significantly different between two or more study groups. We outline these challenges and describe a solution, based on Poisson regression, that allows differences in perinatal morbidity scores to be formally evaluated. The approach is illustrated using an existing maternal-neonatal scoring tool, the Adverse Outcome Index, to evaluate the safety of labour and delivery before and after the closure of obstetrical services in small rural communities. Applying the proposed Poisson regression to the case study showed a protective risk ratio for adverse outcome following closures as compared with the original analysis, where no difference was found. This approach opens the door for considerably broader use of perinatal morbidity scoring tools as a primary outcome in applied population and clinical maternal-infant health research studies. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Diffusion Tensor Imaging of Normal-Appearing White Matter as Biomarker for Radiation-Induced Late Delayed Cognitive Decline

DOE Office of Scientific and Technical Information (OSTI.GOV)

Chapman, Christopher H., E-mail: chchap@umich.edu; Nagesh, Vijaya; Sundgren, Pia C.

Purpose: To determine whether early assessment of cerebral white matter degradation can predict late delayed cognitive decline after radiotherapy (RT). Methods and Materials: Ten patients undergoing conformal fractionated brain RT participated in a prospective diffusion tensor magnetic resonance imaging study. Magnetic resonance imaging studies were acquired before RT, at 3 and 6 weeks during RT, and 10, 30, and 78 weeks after starting RT. The diffusivity variables in the parahippocampal cingulum bundle and temporal lobe white matter were computed. A quality-of-life survey and neurocognitive function tests were administered before and after RT at the magnetic resonance imaging follow-up visits. Results:more » In both structures, longitudinal diffusivity ({lambda}{sub Double-Vertical-Line }) decreased and perpendicular diffusivity ({lambda}{sub Up-Tack }) increased after RT, with early changes correlating to later changes (p < .05). The radiation dose correlated with an increase in cingulum {lambda}{sub Up-Tack} at 3 weeks, and patients with >50% of cingula volume receiving >12 Gy had a greater increase in {lambda}{sub Up-Tack} at 3 and 6 weeks (p < .05). The post-RT changes in verbal recall scores correlated linearly with the late changes in cingulum {lambda}{sub Double-Vertical-Line} (30 weeks, p < .02). Using receiver operating characteristic curves, early cingulum {lambda}{sub Double-Vertical-Line} changes predicted for post-RT changes in verbal recall scores (3 and 6 weeks, p < .05). The neurocognitive test scores correlated significantly with the quality-of-life survey results. Conclusions: The correlation between early diffusivity changes in the parahippocampal cingulum and the late decline in verbal recall suggests that diffusion tensor imaging might be useful as a biomarker for predicting late delayed cognitive decline.« less

Background: Estimation of the outcome is paramount in disease stratification and subsequent management in severely ill surgical patients. Risk scoring helps us quantify the prospects of adverse outcome in a patient. Portsmouth-Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (P-POSSUM) the world over has proved itself as a worthy scoring system and the present study was done to evaluate the feasibility of P-POSSUM as a risk scoring system as a tool in efficacious prediction of mortality and morbidity in our demographic profile. Materials and Methods: Validity of P-POSSUM was assessed prospectively in fifty major general surgeries performed at our hospital from May 2011 to October 2012. Data were collected to obtain P-POSSUM score, and statistical analysis was performed. Results: Majority (72%) of patients was male and mean age was 40.24 ± 18.6 years. Seventy-eight percentage procedures were emergency laparotomies commonly performed for perforation peritonitis. Mean physiological score was 17.56 ± 7.6, and operative score was 17.76 ± 4.5 (total score = 35.3 ± 10.4). The ratio of observed to expected mortality rate was 0.86 and morbidity rate was 0.78. Discussion: P-POSSUM accurately predicted both mortality and morbidity in patients who underwent major surgical procedures in our setup. Thus, it helped us in identifying patients who required preferential attention and aggressive management. Widespread application of this tool can result in better distribution of care among high-risk surgical patients. PMID:28250670

Neoadjuvant radiation therapy (RT) downstages rectal cancer but may increase postoperative morbidity. This study aims to quantify 30-day complication rates after total mesorectal excision (TME) using current techniques and to assess for an association of these complications with neoadjuvant RT. Stage I-III rectal cancer patients who underwent TME from 2005 to 2010 were identified. Complications occurring within 30 days after TME were retrieved from a prospectively maintained institutional database of postoperative adverse events. The cohort consisted of 461 patients. Median age was 59 years (range 18-90), and 274 patients (59 %) were male. Comorbid conditions included obesity (n = 147; 32 %), coronary artery disease (n = 83; 18 %), diabetes (n = 65; 14 %), and inflammatory bowel disease (n = 19; 4 %). A low anterior resection (LAR) was performed in 383 cases (83 %), an abdominoperineal resection (APR) was performed in 72 cases (16 %), and a Hartmann's procedure was performed in 6 cases (1 %). Preoperative RT was delivered to 310 patients (67 %; median dose of 50.4 Gy, range 27-55.8 Gy). The 30-day incidence of postoperative mortality was 0.4 % (n = 2), any complication 25 % (n = 117), grade 3 or more complication 5 % (n = 24), intra-abdominal infection 3 % (n = 12), abdominal wound complication 9 % (n = 42), perineal wound complication after APR 11 % (n = 8/72), and anastomotic leak after LAR 2 % (n = 6/383). These events were not associated with neoadjuvant RT. In a cohort undergoing TME using current techniques, neoadjuvant RT was not associated with 30-day postoperative morbidity or mortality.

International surveys have shown that the leading cause of death after kidney transplantation has cardiovascular origin with a prevalence of 35-40%. As a preventive strategy these patients receive aspirin (ASA) therapy, even though their rate of aspirin resistance is still unknown. In our study, platelet aggregation measurements were performed between 2009 and 2012 investigating the laboratory effect of low-dose aspirin (100 mg) treatment using a CARAT TX4 optical aggregometer. ASA therapy was considered clinically effective in case of low ( i.e., below 40%) epinephrine-induced (10 μM) platelet aggregation index. Rate of aspirin resistance, morbidity and mortality data of kidney transplanted patients (n = 255, mean age: 49 ± 12 years) were compared to a patient population with cardio- and cerebrovascular diseases (n = 346, mean age: 52.6 ± 11 years). Rate of aspirin resistance was significantly higher in the renal transplantation group (RT) compared to the positive control group (PC) (35.9% vs. 25.6%, p < 0.002). Morbidity analysis demonstrated significantly higher incidence of myocardial infarction, hypertension and diabetes mellitus in the RT group (p < 0.05). The subgroup analysis revealed significantly higher incidence of infarction and stroke in the ASA resistant RT group compared to the RT patients without ASA resistance (p < 0.05). Furthermore, the incidence of myocardial infarction and hypertension was significantly higher in the non-resistant RT group than in the group of PC patients without ASA resistance (p < 0.05). These results may suggest that the elevated rate of aspirin resistance contributes to the high cardiovascular mortality after kidney transplantation.

Outcome after treatment of vestibular schwannomas can be evaluated by health providers as mortality, recurrence, performance, and morbidity. Because mortality and recurrence are rare events, evaluation has to focus on performance and morbidity. The latter has mostly been reported by health providers. In the present study, we validate 2 new scales for patient-assessed performance and morbidity in comparison with different outcome tools, such as quality of life (QOL) (European Quality of Life-5 dimensions [EQ-5D]), facial nerve score, and work capacity. There were 167 total patients in a retrospective (n = 90) and prospective (n = 50) cohort of surgically treated vestibular schwannomas. A new patient-assessed morbidity score (paMS), a patient-assessed Karnofsky score (paKPS), the patient-assessed QOL (EQ-5D) score, work capacity, and the House-Brackmann facial nerve score were used as outcome measures. Analysis of paMS components and their relation to other outcomes was done as uni- and multivariate analysis. All outcome instruments, except EQ-5D and paKPS, showed a significant decrease postoperatively. Only the facial nerve score (House-Brackmann facial nerve score) differed significantly between the retrospective and prospective cohorts. Out of the 16 components of the paMS, hearing dysfunction, tear dysfunction, balance dysfunction, and eye irritation were most often reported. Both paMS and EQ-5D correlated significantly with work capacity. Standard QOL and performance instruments may not be sufficiently sensitive or specific to measure outcome at the cohort level after surgical treatment of vestibular schwannomas. A morbidity score may yield more detailed information on symptoms that can be relevant for rehabilitation and occupational training after surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

The Marshall University Family Medicine Residency (MUFMR) implemented its rural track (RT) in 1994 to help achieve its mission of producing primary care physicians for practice in rural areas and West Virginia. This study examined the impact of the RT on the program's training outcomes and assessed the academic equivalence of the RT and traditional track (TT) curricula. The authors analyzed academic outcomes (in-training examination [ITE] scores, board certification rates) and practice outcomes (location and type following graduation) for the 174 MUFMR graduates who entered the program from 1984 through 2006. They compared RT and TT graduates who entered after RT implementation (1994-2006) with each other and with graduates who entered during the decade before implementation (1984-1993). There were differences between the 12 RT and 94 TT graduates in rural practice upon graduation (RT: 83% versus TT: 40%; P<.01) and practice in West Virginia (RT 83% versus TT 68%; P=.34). RT and TT graduates had similar mean increases in ITE scores and board certification rates. The 106 post-implementation graduates had a significantly higher rate of West Virginia practice than did the 68 pre-implementation graduates (70% versus 52%; P=.02). RT development was associated with a substantial increase in MUFMR graduates practicing in West Virginia. RT graduates were more likely than TT graduates to practice in rural areas and in the state upon graduation. RT graduates seem to advance academically as well as their TT counterparts.

Briganti, Alberto, E-mail: briganti.alberto@hsr.it; Joniau, Steven; Gandaglia, Giorgio

Purpose: The aim of our study was to evaluate patterns and predictors of early biochemical recurrence (eBCR) after radical prostatectomy (RP) and adjuvant radiation therapy (aRT) in order to identify which individuals might benefit from additional treatments. Methods and Materials: We evaluated 390 patients with pT{sub 3}N{sub 0} prostate cancer (PCa) receiving RP and aRT at 6 European centers between 1993 and 2006. Patients who were free from BCR at <2 years' follow-up were excluded. This resulted in 374 assessable patients. Early BCR was defined as 2 consecutive prostate-specific antigen (PSA) test values >0.2 ng/mL within 2 or 3 yearsmore » after aRT. Uni- and multivariable Cox regression analyses predicting overall and eBCR after aRT were fitted. Covariates consisted of preoperative PSA results, surgical margins, pathological stage, Gleason score, and aRT dose. Results: Overall, 5- and 8-year BCR-free survival rates were 77.1% and 70.8%, respectively. At a median follow-up of 86 months after aRT, 33 (8.8%) and 55 (14.6%) men experienced BCR within 2 or 3 years after aRT, respectively. In multivariable analyses, Gleason scores of 8 to 10 represented the only independent predictor of eBCR after aRT (all, P≤.01). The risk of BCR was significantly higher in patients with a Gleason score of 8 to 10 disease than in those with Gleason 2 to 6 within 24 months after treatment, after adjusting for all covariates (all, P≤.04). However, given a 24-month BCR free period, the risk of subsequent BCR for men with poorly differentiated disease was equal to that of men with less aggressive disease (all, P≥.3). Conclusions: High Gleason score represents the only predictor of eBCR after RP and aRT in patients affected by pT{sub 3}N{sub 0} PCa. Given the association between early PSA recurrence, clinical progression, and mortality, these patients might be considered candidates for adjuvant medical therapy and/or prophylactic whole-pelvis radiation therapy in addition to aRT, delivered to the prostatic bed.« less

Purpose: To evaluate whether complex radiotherapy (RT) planning was associated with improved outcomes in a cohort of elderly patients with unresected Stage I-II non-small-cell lung cancer (NSCLC). Methods and Materials: Using the Surveillance, Epidemiology, and End Results registry linked to Medicare claims, we identified 1998 patients aged >65 years with histologically confirmed, unresected stage I-II NSCLC. Patients were classified into an intermediate or complex RT planning group using Medicare physician codes. To address potential selection bias, we used propensity score modeling. Survival of patients who received intermediate and complex simulation was compared using Cox regression models adjusting for propensity scoresmore » and in a stratified and matched analysis according to propensity scores. Results: Overall, 25% of patients received complex RT planning. Complex RT planning was associated with better overall (hazard ratio 0.84; 95% confidence interval, 0.75-0.95) and lung cancer-specific (hazard ratio 0.81; 95% confidence interval, 0.71-0.93) survival after controlling for propensity scores. Similarly, stratified and matched analyses showed better overall and lung cancer-specific survival of patients treated with complex RT planning. Conclusions: The use of complex RT planning is associated with improved survival among elderly patients with unresected Stage I-II NSCLC. These findings should be validated in prospective randomized controlled trials.« less

This study aimed to assess head and neck cancer patient satisfaction with the use of a touch-screen computer patient-completed questionnaire for assessing Adult Co-morbidity Evaluation 27 co-morbidity scores prior to treatment, along with its clinical reliability. A total of 96 head and neck cancer patients were included in the audit. An accurate Adult Co-morbidity Evaluation 27 co-morbidity score was achieved via patient-completed questionnaire assessment for 97 per cent of participants. In all, 96 per cent of patients found the use of a touch-screen computer acceptable and would be willing to use one again, and 62 per cent would be willing to do so without help. Patients were more likely to be willing to use the computer again without help if they were aged 65 years or younger (χ2 test; p = 0.0054) or had a performance status of 0 or 1 (χ2 test; p = 0.00034). Use of a touch-screen computer is an acceptable approach for assessing Adult Co-morbidity Evaluation 27 scores at pre-treatment assessment in a multidisciplinary joint surgical-oncology clinic.

Krauze, Andra V.; Myrehaug, Sten D.; Chang, Michael G.

Purpose: Valproic acid (VPA) is an antiepileptic agent with histone deacetylase inhibitor (HDACi) activity shown to sensitize glioblastoma (GBM) cells to radiation in preclinical models. We evaluated the addition of VPA to standard radiation therapy (RT) plus temozolomide (TMZ) in patients with newly diagnosed GBM. Methods and Materials: Thirty-seven patients with newly diagnosed GBM were enrolled between July 2006 and April 2013. Patients received VPA, 25 mg/kg orally, divided into 2 daily doses concurrent with RT and TMZ. The first dose of VPA was given 1 week before the first day of RT at 10 to 15 mg/kg/day and subsequently increased up to 25 mg/kg/daymore » over the week prior to radiation. VPA- and TMZ-related acute toxicities were evaluated using Common Toxicity Criteria version 3.0 (National Cancer Institute Cancer Therapy Evaluation Program) and Cancer Radiation Morbidity Scoring Scheme for toxicity and adverse event reporting (Radiation Therapy Oncology Group/European Organization for Research and Treatment). Results: A total of 81% of patients took VPA according to protocol. Median overall survival (OS) was 29.6 months (range: 21-63.8 months), and median progression-free survival (PFS) was 10.5 months (range: 6.8-51.2 months). OS at 6, 12, and 24 months was 97%, 86%, and 56%, respectively. PFS at 6, 12, and 24 months was 70%, 43%, and 38% respectively. The most common grade 3/4 toxicities of VPA in conjunction with RT/TMZ therapy were blood and bone marrow toxicity (32%), neurological toxicity (11%), and metabolic and laboratory toxicity (8%). Younger age and class V recursive partitioning analysis (RPA) results were significant for both OS and PFS. VPA levels were not correlated with grade 3 or 4 toxicity levels. Conclusions: Addition of VPA to concurrent RT/TMZ in patients with newly diagnosed GBM was well tolerated. Additionally, VPA may result in improved outcomes compared to historical data and merits further study.« less

Body image is associated with self-esteem and identity and has a close relationship with quality of life (QoL). We compared the impact of surgical scars on the patient's perception of body image between conventional open thyroidectomy (OT) and robotic thyroidectomy (RT) in female papillary thyroid carcinoma patients. From October 2009 to December 2010, we enrolled prospectively 116 papillary thyroid carcinoma patients who underwent total thyroidectomy at the Yonsei University Health System (Seoul, Korea). Of these 116 patients, 56 had OT and 60 RT. Their scars were assessed using the Vancouver Scar Scale (VSS), and psychometric properties were evaluated using the Body Image Scale (BIS) questionnaire postoperatively. Both groups were compared using cross-sectional and time-series methods. Mean age was significantly younger in the RT group. Regarding scar quality, the OT group showed superiority in scar pigmentation and the total VSS score during the early postoperative period, but the VSS score improved over time and was similar between both groups at 9 months. The RT group had better scores regarding most of the BIS items, a trend that remained relatively constant over time. In patients with noticeable scars (VSS ≥ 2) at 9 months, the RT group had better BIS scores regarding almost all items, including "self-conscious," "physical attractiveness," "feeling of less feminine," "sexual attractiveness," "dissatisfaction with body, scar and appearance when dressed," and "avoidance of people due to appearance." RT provides a better self-body image and improves QoL compared with conventional OT by avoiding a noticeable cervical scar. Copyright © 2014 Mosby, Inc. All rights reserved.

We investigated whether edaravone could improve early outcomes in acute ischemic stroke patients treated with recombinant tissue plasminogen activator (rtPA). We conducted a retrospective cohort study using the Japanese Diagnosis Procedure Combination database. We identified patients admitted with a primary diagnosis of ischemic stroke from 1 July 2010 to 31 March 2012 and treated with rtPA on the same day of stroke onset or the following day. Thereafter, we selected those who received edaravone on the same day of rtPA administration (edaravone group), and those who received rtPA without edaravone (control group). The primary outcomes were modified Rankin Scale (mRS) scores at discharge. One-to-one propensity-score matching was performed between the edaravone and control groups. An ordinal logistic regression analysis for mRS scores at discharge was performed with adjustment for possible variables as well as clustering of patients within hospitals using a generalized estimating equation. We identified 6336 eligible patients for inclusion in the edaravone group (n=5979; 94%) and the control group (n=357; 6%) as the total population. In 356 pairs of the propensity-matched population, the ordinal logistic regression analysis showed that edaravone was significantly associated with lower mRS scores of patients at discharge (adjusted odds ratio: 0.74; 95% confidence interval: 0.57-0.96). Edaravone may improve early outcomes in acute ischemic stroke patients treated with rtPA. Copyright © 2014 Elsevier B.V. All rights reserved.

Purpose To evaluate and compare the efficacy and safety of two investigational artificial tear formulations (CHO-1 and CHO-2) containing carmellose sodium, hyaluronic acid at different concentrations, and osmoprotectants, with a standard carmellose sodium-containing formulation (Refresh Tears [RT]) in the treatment of dry eye disease. Subjects and methods In this 3-month, double-masked, multicenter study, subjects (n=305) were randomized 1:1:1 to receive CHO-1, CHO-2, or RT, used as needed but at least twice daily. The primary endpoint was change in ocular surface disease index (OSDI) score from baseline to day 90. Other key outcomes included symptoms evaluated on a visual analog scale, corneal and conjunctival staining, and adverse events. Results OSDI scores and dry eye symptoms showed a rapid and sustained reduction from baseline in each group. Both CHO-1 and CHO-2 met the primary efficacy endpoint of noninferiority to RT in day 90 OSDI score change from baseline. OSDI ocular symptoms subscale improved more with CHO-1 than CHO-2 (P=0.048). In subjects with clinically relevant baseline ocular surface staining (>14 total score of a maximum of 55), day 90 improvements were greater with CHO-1 and CHO-2 than RT (P≤0.044). Day 90 improvements in OSDI ocular symptoms subscale scores were also greater with CHO-1 than RT (P<0.007) in subjects with clinically relevant ocular staining. All treatments were well tolerated. Conclusion Both combination artificial tear formulations were efficacious and well tolerated in subjects with dry eye. CHO-1 demonstrated the best performance in improving ocular symptoms and reducing ocular staining in this heterogeneous study population. PMID:25931807

Purpose: The addition of androgen deprivation therapy (ADT) to definitive external beam radiation therapy (RT) improves outcomes in higher-risk prostate cancer patients. However, the benefit of ADT with salvage RT in post-prostatectomy patients is not clearly established. Our study compares biochemical outcomes in post-prostatectomy patients who received salvage RT with or without concurrent ADT. Methods and Materials: Of nearly 2,000 post-prostatectomy patients, we reviewed the medical records of 191 patients who received salvage RT at University of Pennsylvania between 1987 and 2007. Follow-up data were obtained by chart review and electronic polling of the institutional laboratory database and Social Securitymore » Death Index. Biochemical failure after salvage RT was defined as a prostate-specific antigen of 2.0 ng/mL above the post-RT nadir or the initiation of ADT after completion of salvage RT. Results: One hundred twenty-nine patients received salvage RT alone, and 62 patients received combined ADT and salvage RT. Median follow-up was 5.4 years. Patients who received combined ADT and salvage RT were younger, had higher pathologic Gleason scores, and higher rates of seminal vesicle invasion, lymph node involvement, and pelvic nodal irradiation compared with patients who received salvage RT alone. Patients who received combined therapy had improved biochemical progression-free survival (bPFS) compared with patients who received RT alone (p = 0.048). For patients with pathologic Gleason scores {<=}7, combined RT and ADT resulted in significantly improved bPFS compared to RT alone (p = 0.013). Conclusions: These results suggest that initiating ADT during salvage RT in the post-prostatectomy setting may improve bPFS compared with salvage RT alone. However, prospective randomized data are necessary to definitively determine whether hormonal manipulation should be used with salvage RT. Furthermore, the optimal nature and duration of ADT and the patient subgroups in which ADT could provide the most benefit remain open questions.« less

The emergency surgery score is a mortality-risk calculator for emergency general operation patients. We sought to examine whether the emergency surgery score predicts 30-day morbidity and mortality in a high-risk group of patients undergoing emergent laparotomy. Using the 2011-2012 American College of Surgeons National Surgical Quality Improvement Program database, we identified all patients who underwent emergent laparotomy using (1) the American College of Surgeons National Surgical Quality Improvement Program definition of "emergent," and (2) all Current Procedural Terminology codes denoting a laparotomy, excluding aortic aneurysm rupture. Multivariable logistic regression analyses were performed to measure the correlation (c-statistic) between the emergency surgery score and (1) 30-day mortality, and (2) 30-day morbidity after emergent laparotomy. As sensitivity analyses, the correlation between the emergency surgery score and 30-day mortality was also evaluated in prespecified subgroups based on Current Procedural Terminology codes. A total of 26,410 emergent laparotomy patients were included. Thirty-day mortality and morbidity were 10.2% and 43.8%, respectively. The emergency surgery score correlated well with mortality (c-statistic = 0.84); scores of 1, 11, and 22 correlated with mortalities of 0.4%, 39%, and 100%, respectively. Similarly, the emergency surgery score correlated well with morbidity (c-statistic = 0.74); scores of 0, 7, and 11 correlated with complication rates of 13%, 58%, and 79%, respectively. The morbidity rates plateaued for scores higher than 11. Sensitivity analyses demonstrated that the emergency surgery score effectively predicts mortality in patients undergoing emergent (1) splenic, (2) gastroduodenal, (3) intestinal, (4) hepatobiliary, or (5) incarcerated ventral hernia operation. The emergency surgery score accurately predicts outcomes in all types of emergent laparotomy patients and may prove valuable as a bedside decision-making tool for patient and family counseling, as well as for adequate risk-adjustment in emergent laparotomy quality benchmarking efforts.

Predicting the postoperative course of patients with hip fractures would be helpful for surgical planning and risk management. We therefore established equations to predict the morbidity and mortality rates in candidates for hip fracture surgery using the Estimation of Physiologic Ability and Surgical Stress (E-PASS) risk-scoring system. First we evaluated the correlation between the E-PASS scores and postoperative morbidity and mortality rates in all 722 patients surgically treated for hip fractures during the study period (Group A). Next we established equations to predict morbidity and mortality rates. We then applied these equations to all 633 patients with hip fractures treated at seven other hospitals (Group B) and compared the predicted and actual morbidity and mortality rates to assess the predictive ability of the E-PASS and Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) systems. The ratio of actual to predicted morbidity and mortality rates was closer to 1.0 with the E-PASS than the POSSUM system. Our data suggest the E-PASS scoring system is useful for defining postoperative risk and its underlying algorithm accurately predicts morbidity and mortality rates in patients with hip fractures before surgery. This information then can be used to manage their condition and potentially improve treatment outcomes. Level II, prognostic study.

Racial and ethnic disparities in acute stroke care in the United States have been previously reported. This study investigated possible racial and ethnic disparities in the administration and outcome of recombinant tissue plasminogen activator (rtPA) therapy for acute ischemic stroke in whites, blacks, Hispanics, and Asian/Pacific Islanders. Using the National Inpatient Sample for 2001-2008, we selected patients with a primary diagnosis of acute ischemic stroke who received treatment with rtPA. Patient data were stratified by race (white, black, Hispanic, and Asian/Pacific Islander). We analyzed the association of patient race on rtPA utilization rate, in-hospital morbidity (ie, discharge to long-term facility), intracranial hemorrhage (ICH) rate, and in-hospital mortality. We performed a multivariate logistic regression analysis to determine independent predictors of poor outcomes. White patients had a higher rate of tPA utilization than black and Hispanic patients (2.3% vs 1.8% and 2.0%, respectively; P < .0001 for both groups). There was no difference in the rate of tPA utilization between whites and Asian/Pacific Islanders (2.3% vs 2.2% P = .07). Multivariate analysis of morbidity, mortality, and ICH rates found that Asian/Pacific Islanders had significantly higher rates of mortality (odds ratio, 1.22, 95% confidence interval, 1.03-1.44; P = .02) and ICH (odds ratio, 2.01; 95% confidence interval, 1.91-2.11; P < .0001) compared with whites. rtPA utilization was greater in white and Asian/Pacific Islander patients than in black and Hispanic patients. Asian/Pacific Islander race was associated with increased risk of ICH and mortality after rtPA administration. Copyright © 2013. Published by Elsevier Inc.

The Aristotle Comprehensive Complexity (ACC) score has been proposed for complexity adjustment in the analysis of outcome after congenital heart surgery. The score is the sum of the Aristotle Basic Complexity score, largely used but poorly related to mortality and morbidity, and of the Comprehensive Complexity items accounting for comorbidities and procedure-specific and anatomic variability. This study aims to demonstrate the ability of the ACC score to predict 30-day mortality and morbidity assessed by the length of the intensive care unit (ICU) stay. We retrospectively enrolled patients undergoing congenital heart surgery in our institution. We modeled the ACC score as a continuous variable, mortality as a binary variable, and length of ICU stay as a censored variable. For each mortality and morbidity model we performed internal validation by bootstrapping and assessed overall performance by R(2), calibration by the calibration slope, and discrimination by the c index. Among all 1,454 patients enrolled, 30-day mortality rate was 3.4% and median length of ICU stay was 3 days. The ACC score strongly related to mortality, but related to length of ICU stay only during the first postoperative week. For the mortality model, R(2) = 0.24, calibration slope = 0.98, c index = 0.86, and 95% confidence interval was 0.82 to 0.91. For the morbidity model, R(2) = 0.094, calibration slope = 0.94, c index = 0.64, and 95% confidence interval was 0.62 to 0.66. The ACC score predicts 30-day mortality and length of ICU stay during the first postoperative week. The score is an adequate tool for complexity adjustment in the analysis of outcome after congenital heart surgery. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Introduction Pediatric brain tumor survivors are at risk for working memory and processing speed impairment. The General Ability Index (GAI) provides an estimate of intellectual functioning that is less influenced by working memory and processing speed than a Full Scale IQ (FSIQ). The Cognitive Proficiency Index (CPI) provides a measure of efficient information processing derived from working memory and processing speed tasks. We examined the utility of the GAI and CPI to quantify neurocognitive outcomes in a sample of pediatric brain tumor survivors. Methods GAI, CPI, and FSIQ scores from the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) were examined for 57 pediatric brain tumor survivors (ages 6–16) treated with cranial radiation therapy (RT). Results GAI scores were higher than FSIQ and CPI scores, both p < .001. Lower CPI scores were associated with history of craniospinal irradiation and time since RT. Lower FSIQ and GAI scores were associated with higher RT dose and time since RT. The rate of clinically significant GAI-FSIQ discrepancies in our sample was greater than observed in the WISC-IV standardization sample, p < .001. Estimated premorbid IQ scores were higher than GAI, p < .01, and FSIQ scores, p < .001. Conclusions Pediatric brain tumor survivors exhibit weaker cognitive proficiency than expected for age, while general reasoning ability remains relatively spared. The GAI may be useful to quantify the intellectual potential of a survivor when appropriate accommodations are in place for relative cognitive proficiency weaknesses. The CPI may be a particularly sensitive outcome measure of treatment-related cognitive change in this population. PMID:27295192

The objective of the present retrospective analysis was the response evaluation regarding bone density and stability of patients with osteolytic spinal bone lesions due to multiple myeloma after palliative radiotherapy (RT). Patients with multiple myeloma who had undergone spinal RT from March 2003 to May 2016 were analyzed before and 3 and 6 months after RT. Assessment of spinal stability and bone density was performed using the internationally recognized Taneichi scoring system and measurement of bone density using computed tomography imaging-based Hounsfield units. For statistical analysis, we used the Bowker test, McNemar test, and κ statistics to detect possible asymmetries in the distribution of the Taneichi score over time. We used the Student t test for comparison of the density values (Hounsfield units) before and after treatment. Toxicity was evaluated using the Common Terminology Criteria for Adverse Events, version 4.0. Additionally, overall survival was calculated using the Kaplan-Meier method. We evaluated 130 patients (69% male; 31% female) with multiple myeloma and a median age of 58 years. The median follow-up period was 41 months. Before treatment, 51% of the lesions were classified as unstable. At 3 and 6 months after RT, this rate had decreased to 41% (P = .0047) and 24% (P = .2393), respectively. The computed tomography measurements showed a significant increase in bone density at 3 and 6 months after RT. Acute RT-related grade 1 and 2 complications were detected in 34% of patients. Late side effects (grade 1-2) were detected in 23% of the patients. No severe grade 3 or 4 acute or late toxicities were identified. The median overall survival was 19.7 months for all patients and 6.6 months for patients with a Karnofsky performance score of ≤ 70%. To the best of our knowledge, ours is the first report to analyze the bone density and stability in patients with multiple myeloma after RT using a validated scoring system and computed tomography imaging. Palliative RT is an effective method resulting in a significant increase in bone density for local response and stability without severe RT-related toxicity. Furthermore, recalcification could already be detected at 3 months after treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

The Aristotle basic complexity (ABC) score (1.5-15 points) is the sum of potentials for early mortality, morbidity and anticipated surgical technique difficulty. The Aristotle comprehensive complexity (ACC) score (1.5-25 points) is the sum of ABC score and patient-adjusted complexity score; it comprises six complexity levels. We used the ACC score to evaluate quality in surgical management of congenital heart disease. Procedures performed in year 2002 and 2007 were analysed. Proportion of procedures requiring at least 1 week of stay in the intensive care unit was chosen as the marker of morbidity. We adopted threshold duration of 120 min for cardio-pulmonary bypass (CPB) cases and the same duration for operations without CPB as surrogate of surgical technical difficulty. The ACC scores were correlated to mortality, morbidity and technical difficulty. This study included 758 patients who underwent 787 primary procedures. The mean ABC and ACC scores amounted to 7.61+/-2.46 and 9.51+/-3.84. Early mortality was 3.05% (24/787), 95% confidence interval (CI): 1.97-4.51%. Zero at ACC levels 1 and 2, it increased from 1.2% (2/161) for level 3 up to 22.2% (2/9) for level 6. Morbidity index was evaluated at 25.9% (204/787), 95% CI: 22.9-29.1%. 1.9% at level 1, it escalated up to 77.8% at level 6. Index of technique difficulty was estimated at 35.2% (277/787), 95% CI: 31.8-38.6%, ranging from 4.8% for level 1 to 66.7% for level 6. A high correlation was found between the ACC scores and mortality, indices of morbidity and technique difficulty, Spearman's correlation coefficient r being 0.9856, 1 and 0.9429, respectively. Mortality (p=0.037) and morbidity (p=0.041) were lower in year 2007 than in 2002 with ABC (p=0.18) and ACC (p=0.37) surgical performance being not significantly different. The Aristotle score is still under development. Morbidity evaluation should be ideally based on observed postoperative complications; estimation of surgical technical difficulty chosen in this study may not be generalised. Nevertheless, the actual Aristotle comprehensive complexity score, as evaluated in its three components, accurately determined the outcome of surgical management of congenital heart disease. It appears to be an adequate tool to evaluate quality in paediatric cardiac surgery, over time. Copyright 2009 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.

The aim of the present study was to predict operative morbidity in elderly patients with deep pressure sores by using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) scoring system. Fifteen patients over 70 years old were retrospectively reviewed who had undergone gluteus maximus fasciocutaneous flap-reconstruction for pressure sores of the sacral region from 1 April 2005 to 31 March 2007. Complications were seen in six cases (40%) after operation. Four were wound infection, one was chest infection and another was septicemia. The subjects were divided into two groups by the presence (complicated group) or absence (non-complicated group) of postoperative complications. Each item of physiological scores, physiological score (PS), operative severity score (OS) and predicted morbidity rate (R) were calculated and compared between two groups. As a result, hemoglobin (P = 0.0276), PS (P = 0.0023) and R (P = 0.0078) differed significantly between the two groups. It is noteworthy that the PS were over 25 in all of the complicated group, but in only one of nine in the non-complicated group (P = 0.0014). Our study suggests that, for pressure sores in the sacral region in elderly patients, gluteus maximus fasciocutaneous flap-reconstruction can be employed in patients whose PS are under 24 in the POSSUM scoring system.

Continuous quality improvement (CQI) collaboration has not eliminated the morbidity variability seen among neonatal intensive care units (NICUs). Factors other than inconstant application of potentially better practices (PBPs) might explain divergent proficiency. Measure a composite morbidity score and determine whether cultural, environmental and cognitive factors distinguish high proficiency from lower proficiency NICUs. Retrospective analysis using a risk-adjusted composite morbidity score (Benefit Metric) and cultural survey focusing on very low birth weight (VLBW) infants from 39 NICUs, years 2000-2014. The Benefit Metric and yearly variance from the group mean was rank-ordered by NICU. A comprehensive survey was completed by each NICU exploring whether morbidity variance correlated with CQI methodology, cultural, environmental and/or cognitive characteristics. 58 272 VLBW infants were included, mean (SD) age 28.2 (3.0) weeks, birth weight 1031 (301) g. The 39 NICU groups' Benefit Metric improved 40%, from 80 in 2000 to 112 in 2014 (P<0.001). 14 NICUs had composite morbidity scores significantly better than the group, 16 did not differ and 9 scored below the group mean. The 14 highest performing NICUs were characterised by more effective team work, superior morale, greater problem-solving expectations of providers, enhanced learning opportunities, knowledge of CQI fundamentals and more generous staffing. Cultural, environmental and cognitive characteristics vary among NICUs perhaps more than traditional CQI methodology and PBPs, possibly explaining the inconstancy of VLBW infant morbidity reduction efforts. High proficiency NICUs foster spirited team work and camaraderie, sustained learning opportunities and support of favourable staffing that allows problem solving and widespread involvement in CQI activities. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Introduction National guidance states that all patients having emergency surgery should have a mortality risk assessment calculated on admission so that the ‘high risk’ patient can receive the appropriate seniority and level of care. We aimed to assess if peri-operative risk scoring tools could accurately calculate mortality and morbidity risk. Methods Mortality risk scores for 86 consecutive emergency laparotomies, were calculated using pre-operative (ASA, Lee index) and post-operative (POSSUM, P-POSSUM and CR-POSSUM) risk calculation tools. Morbidity risk scores were calculated using the POSSUM predicted morbidity and compared against actual morbidity according to the Clavien–Dindo classification. Results The actual mortality was 10.5%. The average predicted risk scores for all laparotomies were: ASA 26.5%, Lee Index 2.5%, POSSUM 29.5%, P-POSSUM 18.5%, CR-POSSUM 10.5%. Complications occurred following 67 laparotomies (78%). The majority (51%) of complications were classified as Clavien–Dindo grade 2–3 (non-life-threatening). Patients having a POSSUM morbidity risk of greater than 50% developed significantly more life-threatening complications (CD 4–5) compared with those who predicted less than or equal to 50% morbidity risk (P = 0.01). Discussion Pre-operative risk stratification remains a challenge because the Lee Index under-predicts and ASA over-predicts mortality risk. Post-operative risk scoring using the CR-POSSUM is more accurate and we suggest can be used to identify patients who require intensive care post-operatively. Conclusions In the absence of accurate risk scoring tools that can be used on admission to hospital it is not possible to reliably audit the achievement of national standards of care for the ‘high-risk’ patient.

Purpose: Assessment of androgen deprivation therapy (ADT) benefits for prostate cancer treated with dose-escalated radiotherapy (RT). Methods and Materials: From 1991 to 2004, 1,044 patients with intermediate- (n = 782) or high-risk (n = 262) prostate cancer were treated with dose-escalated RT at William Beaumont Hospital. Patients received external-beam RT (EBRT) alone, brachytherapy (high or low dose rate), or high dose rate brachytherapy plus pelvic EBRT. Intermediate-risk patients had Gleason score 7, prostate-specific antigen (PSA) 10.0-19.9 ng/mL, or Stage T2b-T2c. High-risk patients had Gleason score 8-10, PSA {>=}20, or Stage T3. Patients were additionally divided specifically by Gleason score, presencemore » of palpable disease, and PSA level to further define subgroups benefitting from ADT. Results: Median follow-up was 5 years; 420 patients received ADT + dose-escalated RT, and 624 received dose-escalated RT alone. For all patients, no advantages in any clinical endpoints at 8 years were associated with ADT administration. No differences in any endpoints were associated with ADT administration based on intermediate- vs. high-risk group or RT modality when analyzed separately. Patients with palpable disease plus Gleason {>=}8 demonstrated improved clinical failure rates and a trend toward improved survival with ADT. Intermediate-risk patients treated with brachytherapy alone had improved biochemical control when ADT was given. Conclusion: Benefits of ADT in the setting of dose-escalated RT remain poorly defined. This question must continue to be addressed in prospective study.« less

Robotic telerounding is effective from the standpoint of patients' satisfaction and patients' care in teaching and community hospitals. However, the impact of robotic telerounding by the intensivist rounding remotely in the surgical intensive care unit (SICU), on patients' outcome and on the education of medical students physician assistants and surgical residents, as well as on nurses' satisfaction has not been studied. Prospective evaluation of robotic telerounding (RT) using a Likert Scale measuring tool to assess whether it can replace conventional rounding (CR) from the standpoint of patients' care and outcome, nursing satisfaction, and educational effectiveness. RT did not have a negative impact on patients' outcome during the study interval: mortality 5/42 (12 %) versus 6/37 (16 %), RT versus CR, respectively, p = 0.747. The intensivists rounding in the SICU were satisfied with their ability to deliver the same patients' care remotely (Likert score 4.4 ± 0.2). The educational experience of medical students, physicia assistants, and surgical residents was not affected by RT (average Likert score 4.5 ± 0.2, 3.9 ± 0.4, and 4.4 ± 0.4 for surgical residents, medical students and PAs, respectively, p > 0.05). However, as shown by a Likert score of 3.5 ± 1.0, RT did not meet nurses' expectations from several standpoints. Intensivists regard robotic telerounding as an effective alternative to conventional rounding from the standpoint of patients' care and teaching. Medical students, physician assistants (PA's), and surgical residents do not believe that RT compromises their education. Despite similar patients' outcome, nurses have a less favorable opinion of RT; they believe that the physical presence of the intensivist is favorable at all times.

Objective: To observe the effects of functional training combined with self-made hand flexing training band in treatment of scar contracture after burn injury of dorsal hand. Methods: Forty-six patients with scar contracture after deep partial-thickness or full-thickness burn injury of dorsal hand hospitalized in our department from March 2013 to February 2015 were divided into routine training group (RT, n =18) and comprehensive training group (CT, n =28) according to their willingness. Two weeks after the wounds were healed, patients in group RT were treated with functional training of hands and self-made pressure gloves, while patients in group CT were treated with self-made hand flexing training band (consisting of nylon strap, flexing band, and velcro) on the basis of those in group RT. All patients were treated for 3 months. Before and after treatment, scar condition of affected hands was assessed with Vancouver Scar Scale (VSS). The range of motion of joints of affected hands was measured by Total Active Movement (TAM) Scale. The function of affected hands was evaluated by Carroll Upper Extremity Function Test. Data were processed with t test, chi-square test, and Mann-Whitney U test. Results: (1) The score of VSS in patients of group RT was (10.0±1.9) points before treatment and (4.4±1.4) points after treatment, with the improved score of (5.6±1.0) points. The score of VSS in patients of group CT was (10.5±1.8) points before treatment and (4.6±1.4) points after treatment, with the improved score of (5.9±1.2) points. There was no statistically significant difference in the improved score of patients between the two groups ( t =0.834, P >0.05). The score of VSS in patients of groups RT and CT after treatment was significantly lower than that before treatment (with t values respectively 14.014 and 10.003, P values below 0.01). (2) Before treatment, the ratios of excellent and good results according to TAM were 2/9 in patients of group RT and 3/14 in group CT, with no statistical differences between them ( χ (2)=2.140, P >0.05). After treatment, the ratio of excellent and good results according to TAM in patients of group CT (6/7) was higher than that in group RT (5/9, χ (2)=0.023, P =0.038). The ratios of excellent and good results according to TAM in patients of groups RT and CT after treatment were significantly higher than those before treatment (with Z values respectively -2.023 and -4.780, P values below 0.05). (3) The improved score of hand function in patients of group CT was (26±12) points, which was higher than (15±7) points in group RT ( t =3.278, P =0.002). The score of hand function in patients of groups RT and CT after treatment was significantly higher than that before treatment (with t values respectively 2.628 and 6.125, P values below 0.05). There were no significant differences in grades of hand function of patients between the two groups before treatment ( Z =-0.286, P >0.05). After treatment, the grade of hand function in patients of group CT was higher than that in group RT( Z =-1.993, P =0.046). The grades of hand function in patients of groups RT and CT after treatment were significantly higher than those before treatment (with Z values respectively -2.717 and -4.998, P values below 0.01). Conclusions: For patients with scar contracture after burn injury of dorsal hand, early functional training combined with hand flexing training band can improve the range of motion of hand joints and functional recovery of hand, and the result was better than functional training alone.

Mucositis is an adverse effect of chemotherapy (QT) and/or radiotherapy (RT). The purpose of this study was to investigate the occurrence of oral mucositis in children undergoing cancer treatment. Fifty-one children with cancer who had received QT, RT, or both (QT-RT) underwent clinical evaluations; World Health Organization criteria were used to establish the degree and severity of mucositis. The correlations between the clinical data, type of cancer, and therapy were statistically analysed. Mucositis was present in 88.23% of the patients; 57.78%, 7.78%, and 24.44% received QT, RT, and QT-RT, respectively. Severity scores of 1 and 2 were the most common; scores of 3-4 were observed in patients who received QT-RT or more than 7 treatment cycles. There was a significant association between mucositis, the type of treatment, and the number of cycles received ( p < 0.05). It is important to implement therapeutic protocols that help maintain excellent oral health and reduce the risk of oral mucositis. Stomatologists should be consulted to assess patients' oral cavities and provide preventive treatment prior to QT and/or RT administration. It is important to integrate a stomatologist into the oncological working group to focus on preventing and managing oral mucositis.

WE-FG-202-11: Longitudinal Diffusion MRI for Treatment Assessment of Sarcoma Patients with Pre-Operative Radiation Therapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Yang, Y; Cao, M; Kamrava, M

Purpose: Diffusion weighted MRI (DWI) is a promising imaging technique for early prediction of tumor response to radiation therapy. A recently proposed longitudinal DWI strategy using a Co-60 MRI guided RT system (MRIgRT) may bring functional MRI guided adaptive radiation therapy closer to clinical utility. We report our preliminary results of using this longitudinal DWI approach performed on the MRIgRT system for predicting the response of sarcoma patient to preop RT. Methods: Three sarcoma patients who underwent fractionated IMRT were recruited in this study. For all three patients DWI images were acquired immediately following his/her treatment. For each imaging session,more » ten slices were acquired interleaved with the b values covering the gross tumor volume (GTV). The diffusion images were processed to obtain the ADC maps using standard exponential fitting for each voxel. Regions of interest were drawn in the tumor on the diffusion images based on each patient’s clinical GTV contours. Each patient subsequently underwent surgery and the tumor necrosis score was available from standard pathology. The ADC values for each patient were compared to the necrosis scores to assess the predictive value of our longitudinal DWI for tumor response. Results: Each patient underwent 3 to 5 diffusion MRI scans depending on their treatment length. Patient 1 had a relatively unchanged ADC during the course of RT and a necrosis score of 30% at surgery. For patient 2, the mean ADC values decreased from 1.56 × 10-3 to 1.12 × 10-3 mm2/s and the patient’s necrosis score was less than 10%. Patient 3 had a slight increase in the ADC values from 0.59 × 10-3 to 0.71 × 10-3 mm2/s and patient’s necrosis score was 50%. Conclusion: Based on limited data from 3 patients, our longitudinal changes in tumor ADC assessed using the MRIgRT system correlated well with pathology results.« less

Assessment of quality of life in patients with rectal cancer treated by preoperative radiotherapy: A longitudinal prospective study

2005-03-15

Purpose: To assess prospectively the quality of life (QOL) of patients treated by preoperative radiotherapy (RT) and surgery for locally advanced rectal cancer. Methods and materials: We studied 53 patients treated with bi-fractionated RT (50 Gy in 40 fractions within 4 weeks) followed at a median interval of 45 days by abdominoperineal resection in 11 patients and low anterior resection in 42 patients. Their QOL was assessed using two self-rating questionnaires developed by the European Organization for Research and Treatment of Cancer (EORTC): one was cancer specific (EORTC QLQ-C30) and one was site specific (EORTC QLQ-C38). The questionnaires were completedmore » before RT and 12-16 months after RT, at which time 17 patients had undergone colostomy. We hypothesized that at least some scores of the various scales would vary between the two analyses. Results: Compared with the pre-RT scores, at 1 year, patients reported statistically significant improvement in their emotional state (median 75 vs. 100, p <0.0001), perspective of the future (67 vs. 100, p = 0.0004), and their global QOL (75 vs. 83, p = 0.0008), as well as a decrease in GI symptoms (13 vs. 0, p = 0.002). However, the sexual dysfunction score increased significantly, particularly in men (17 vs. 83, p = 0.0045), and a trend toward a lower body image score was observed (100 vs. 89, p = 0.068). At 1 year, patients with colostomies reported similar or significantly improved symptom scores for fatigue, pain, GI problems, and sleep disturbance, but no such improvements were observed in patients without stomas. Conclusion: One year after combined treatment for locally advanced rectal cancer, patients exhibited statistically significant improvement in some important QOL outcomes, including global QOL, despite a decrease in sexual function and body image. Any additional improvement in QOL outcome may require refinements in the RT and surgical techniques to reduce late sequelae, particularly sexual dysfunction. Our results suggest that QOL considerations do not justify sphincter-conserving approaches if locoregional tumor control would be compromised.« less

The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) and Portsmouth POSSUM (P-POSSUM) use preoperative and intraoperative factors to evaluate risk. We examined our surgical results to investigate predictive factors for morbidity and mortality, and evaluate the accuracy of the POSSUM and P-POSSUM. Patients (n = 593) aged ≥80 years, undergoing general surgical procedures were enrolled. Logistic regression analysis was used to determine the independent predictors. The predicted outcomes using POSSUM and P-POSSUM were also compared with actual outcomes. Physiological score (PS) and operative severity score (OS) were independent predictors of morbidity and mortality. Using POSSUM, the observed/expected (O/E) morbidity ratio was 1.44 and O/E mortality ratio was 0.98. Using P-POSSUM, the O/E mortality ratio was 1.0. Even though POSSUM tended to underestimate the morbidity rate, POSSUM and P-POSSUM accurately predicted the mortality rate after general surgical procedures.

Esophageal resection in patients with esophageal cancer (EC) is still associated with high mortality and morbidity rates. We aimed to develop a simple preoperative risk score for the prediction of short-term and long-term outcomes for patients with EC treated by esophageal resection. In total, 498 patients suffering from esophageal carcinoma, who underwent esophageal resection, were included in this retrospective cohort study. Three preoperative esophagectomy risk (PER) groups were defined based on preoperative functional evaluation of different organ systems by validated tools (revised cardiac risk index, model for end-stage liver disease score, and pulmonary function test). Clinicopathological parameters, morbidity, and mortality as well as disease-free survival (DFS) and overall survival (OS) were correlated to the PER score. The PER score significantly predicted the short-term outcome of patients with EC who underwent esophageal resection. PER 2 and PER 3 patients had at least double the risk of morbidity and mortality compared to PER 1 patients. Furthermore, a higher PER score was associated with shorter DFS (P < 0.001) and OS (P < 0.001). The PER score was identified as an independent predictor of tumor recurrence (hazard ratio [HR] 2.1; P < 0.001) and OS (HR 2.2; P < 0.001). The PER score allows preoperative objective allocation of patients with EC into different risk categories for morbidity, mortality, and long-term outcomes. Thus, multicenter studies are needed for independent validation of the PER score.

Patients with perforated peptic ulcer (PPU) often present with acute, severe illness that carries a high risk for morbidity and mortality. Mortality ranges from 3-40% and several prognostic scoring systems have been suggested. The aim of this study was to review the available scoring systems for PPU patients, and to assert if there is evidence to prefer one to the other. We searched PubMed for the mesh terms "perforated peptic ulcer", "scoring systems", "risk factors", "outcome prediction", "mortality", "morbidity" and the combinations of these terms. In addition to relevant scores introduced in the past (e.g. Boey score), we included recent studies published between January 2000 and December 2012) that reported on scoring systems for prediction of morbidity and mortality in PPU patients. A total of ten different scoring systems used to predict outcome in PPU patients were identified; the Boey score, the Hacettepe score, the Jabalpur score the peptic ulcer perforation (PULP) score, the ASA score, the Charlson comorbidity index, the sepsis score, the Mannheim Peritonitis Index (MPI), the Acute physiology and chronic health evaluation II (APACHE II), the simplified acute physiology score II (SAPS II), the Mortality probability models II (MPM II), the Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity physical sub-score (POSSUM-phys score). Only four of the scores were specifically constructed for PPU patients. In five studies the accuracy of outcome prediction of different scoring systems was evaluated by receiver operating characteristics curve (ROC) analysis, and the corresponding area under the curve (AUC) among studies compared. Considerable variation in performance both between different scores and between different studies was found, with the lowest and highest AUC reported between 0.63 and 0.98, respectively. While the Boey score and the ASA score are most commonly used to predict outcome for PPU patients, considerable variations in accuracy for outcome prediction were shown. Other scoring systems are hampered by a lack of validation or by their complexity that precludes routine clinical use. While the PULP score seems promising it needs external validation before widespread use.

To examine the usefulness of a biomechanical measure, resistance torque (RT), in quantifying spasticity by comparing its use with a clinical scale, the modified Ashworth scale (MAS), and quantitative electrophysiological measures. This is a correlational study of spasticity measurements in 34 adults with traumatic brain injury and plantarflexor spasticity. Plantarflexor spasticity was measured in the seated position before and after cryotherapy using the MAS and also by strapping each subject's foot and ankle to an apparatus that provided a ramp and hold stretch. The quantitative measures were (1) reflex threshold angle (RTA) calculated through electromyographic signals and joint angle traces, (2) Hdorsiflexion (Hdf)/Hcontrol (Hctrl) amplitude ratio obtained through reciprocal inhibition of the soleus H-reflex, (3) Hvibration (Hvib)/Hctrl ratio obtained through vibratory inhibition of the soleus H-reflex, and (4) RT calculated as the time integral of the torque graph between the starting and ending pulses of the stretch. Correlation coefficients between RT and MAS scores in both pre-ice (0.41) and post-ice trials (0.42) were fair (P = 0.001). The correlation coefficients between RT scores and RTA scores in both the pre-ice (0.66) and post-ice trials (0.75) were moderate (P

Robotic versus Open Thyroidectomy for Differentiated Thyroid Cancer: An Evidence-Based Review.

2016-01-01

While open thyroidectomy (OT) is advocated as the gold standard treatment for differentiated thyroid cancer, the contemporary use of robotic thyroidectomy (RT) is often controversial. Although RT combines the unique benefits of the surgical robot and remote access thyroidectomy, its applicability on cancer patients is challenged by the questionable oncological benefits and safety. This review aims to analyze the current literature evidence in comparing RT to OT on thyroid cancers for their perioperative and oncological outcomes. To date, no randomized controlled trial is available in comparing RT to OT. All published studies are nonrandomized or retrospective comparisons. Current data suggests that RT compares less favorably than OT for longer operative time, higher cost, and possibly inferior oncological control with lower number of central lymph nodes retrieved. In terms of morbidity, quality of life outcomes, and short-term recurrence rates, RT and OT are comparable. While conventional OT continues to be appropriate for most thyroid cancers, RT should better be continued by expert surgeons on selected patients who have low-risk thyroid cancers and have high expectations on cosmetic outcomes. Future research should embark on prospective randomized studies for unbiased comparisons. Long-term follow-up studies are also needed to evaluate outcomes on recurrence and survival.

This study was conducted to evaluate quality of life (QOL) and functional outcome in patients with carcinomas of the larynx and hypopharynx treated with accelerated radiotherapy (RT). Between January 1991 and September 1996, 21 patients treated with accelerated concomitant boost RT schedule (69.9 Gy in 5. 5 weeks) for laryngeal (n = 10) or hypopharyngeal (n = 11) carcinomas and who remained free of disease at 1-year minimum follow-up were evaluated. The functional outcome was assessed by the subjective Performance Status Scale for Head and Neck cancer (PSSHN) and general QOL by the European Organization for Research and Treatment of Cancer Core QOL questionnaire (EORTC QLQ-C30). The median length of follow-up was 37 months (range, 13 to 75). The PSSHN scores were 89, 84, and 86, respectively, for eating in public, understandability of speech and normalcy of diet (100 = normal function). Significantly lower scores for understandability of speech were observed in patients with advanced and laryngeal carcinomas. Normalcy of diet was affected negatively by the severity of xerostomia. All mean functional scale scores of the EORTC QLQ-C30 module were 20% to 25% below the higher score. Most of these scale scores were significantly affected by the severity of xerostomia. Patients treated with concomitant boost RT for laryngeal and hypopharyngeal carcinomas appear to have similar QOL and functional outcome to those reported for patients treated with conventional or hyperfractionated RT. As expected, many QOL scales were affected by the severity of xero- stomia.

A randomized phase II study was performed to measure the potential therapeutic effects of yoga on fatigue, erectile dysfunction, urinary incontinence, and overall quality of life (QOL) in prostate cancer (PCa) patients undergoing external beam radiation therapy (RT). The participants were randomized to yoga and no-yoga cohorts (1:1). Twice-weekly yoga interventions were offered throughout the 6- to 9-week courses of RT. Comparisons of standardized assessments were performed between the 2 cohorts for the primary endpoint of fatigue and the secondary endpoints of erectile dysfunction, urinary incontinence, and QOL before, during, and after RT. From October 2014 to January 2016, 68 eligible PCa patients underwent informed consent and agreed to participate in the study. Of the 68 patients, 18 withdrew early, mostly because of treatment schedule-related time constraints, resulting in 22 and 28 patients in the yoga and no-yoga groups, respectively. Throughout treatment, those in the yoga arm reported less fatigue than those in the control arm, with global fatigue, effect of fatigue, and severity of fatigue subscales showing statistically significant interactions (P<.0001). The sexual health scores (International Index of Erectile Function Questionnaire) also displayed a statistically significant interaction (P=.0333). The International Prostate Symptom Score revealed a statistically significant effect of time (P<.0001) but no significant effect of treatment (P=.1022). The QOL measures had mixed results, with yoga having a significant time by treatment effect on the emotional, physical, and social scores but not on functional scores. A structured yoga intervention of twice-weekly classes during a course of RT was associated with a significant reduction in pre-existing and RT-related fatigue and urinary and sexual dysfunction in PCa patients.

Purpose The NCIC CTG PR3/MRC PR07 randomized phase III trial compared androgen-deprivation therapy (ADT) alone versus ADT with radiotherapy (RT) for patients with locally advanced prostate cancer. This article reports the health-related quality-of-life (HRQOL) outcomes of this trial. Patients and Methods A total of 1,205 patients were randomly allocated to either ADT alone or ADT with RT. HRQOL was assessed at baseline and every 6 months thereafter using the European Organisation for Research and Treatment of Cancer Core Questionnaire and a prostate cancer–specific checklist or the Functional Assessment of Cancer Therapy–Prostate questionnaire. Mean changes from baseline scores for five function domains and nine symptom domains were analyzed as those most relevant to ADT and RT. The proportions of patients with improved, stable, or worsened HRQOL scores according to instrument-specific minimal important differences were calculated. Results Baseline questionnaires were completed by 1,028 patients (88%). At 6 months, RT had a statistically significant impact on mean score for bowel symptoms (P = .02), diarrhea (P < .001), urinary function (P = .003), and erectile dysfunction (P = .008); by 3 years, however, there were no significant between-group differences in any domain. Generalized linear mixed modeling revealed no significant between-arm differences in any of the function scales but showed significant deterioration in both arms over time for Functional Assessment of Cancer Therapy–Prostate total score, treatment outcome index, and physical and functional well-being. Conclusion The addition of RT to ADT for patients with locally advanced prostate cancer significantly improved overall survival and had only modest and transient negative impact on relevant domains of HRQOL.

Purpose: After radiation therapy (RT), various radiation-induced toxicities can develop in about one-fourth of patients. An international interest in using morbidity and mortality rates to monitor the quality of care and integrate morbidity and mortality review (MMR) meetings into organizations' governance processes has arisen. We report the first results of patients included in our MMR procedure that included biological assays for individual intrinsic radiosensitivity (IIRS). Methods and Materials: Twenty-three patients were prospectively included in the MMR database. Twenty-two were evaluable for IIRS. Prostate (n=10) and breast (n=8) cancers were the most frequent disease types. The total dose delivered, determined according tomore » the type of disease, ranged from 30 to 74 Gy. Our MMR procedure requires strict criteria: patients with unresolved toxicity of grade 3 or higher with availability of clinical (photographic) data, IIRS results obtained from skin biopsy assays, treatment modalities, and follow-up data. The RT technique and dosimetry were reviewed. Results: Our prospective registration of toxicities showed mainly rectitis, occurring in 7 cases, and skin toxicities, occurring in 9. Of the 7 patients with rectitis, 5 received 66 Gy of post-prostatectomy RT with V50 (rectum volume receiving 50 Gy) ranging from 45% to 75% and a mean maximal dose of 66.5 Gy. For dermatitis and cystitis, the mean maximal doses were in the range of classical constraints without any overdosage or dose heterogeneity. No errors were found in the review of treatment planning and positioning. Conversely, all the patients were considered biologically as radiosensitive with genomic instability and ATM (ataxia telangiectasia mutated)-dependent DNA double-strand break repair impairments. Conclusions: The MMR review of files allowed clear answers for patients on the relationship between clinical events and their IIRS. Our procedure has allowed education of all our staff to monitor, identify, and document clinical, physical, and biological aspects of radiation-induced toxicities. Thus we recommend the introduction of the MMR procedure in RT departments.« less

The present study was conducted to determine the preventive efficacy of vitamin C/E complex supplementation for radiotherapy (RT)-induced xerostomia in patients with head and neck cancer. Prospective, double-blinded, randomized, placebo-controlled study. A single tertiary referral institution. The trial group (n = 25) received antioxidant supplements (100 IU of vitamin E + 500 mg of vitamin C) twice per day during RT, while the control group (n = 20) received an identical placebo. Pre-RT and 1 and 6 months post-RT, patient-reported xerostomia questionnaires, observer-rated xerostomia score, and salivary scintigraphy were serially obtained to compare xerostomia severity between the 2 groups. The trial group showed greater improvements in xerostomia questionnaire and score at 6 months post-RT when compared with those at 1 month post-RT (P = .007 and .008, respectively). In contrast, the control group showed no changes between 1 and 6 months post-RT. By salivary scintigraphy, there was no difference in maximal accumulation or ejection fraction between the 2 groups. However, the trial group maintained significantly better oral indices at the prestimulatory (P = .01) and poststimulatory (P = .009) stages at 1 month post-RT, compared with the control group. At the final follow-up, there was no difference in overall survival and disease-free survival between the 2 groups. Our data suggest that short-term supplementation with an antioxidant vitamin E/C complex exerts a protective effect against RT-induced xerostomia. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

This pilot study examined whether breast cancer patients with childhood trauma exhibit increased fatigue, depression, and stress in association with inflammation as a result of whole breast radiotherapy (RT). Twenty breast cancer patients were enrolled in a prospective, longitudinal study of fatigue, depression, and perceived stress prior to RT, week 6 of RT, and 6 weeks post-RT. Six weeks after RT, subjects completed the childhood trauma questionnaire (CTQ). Patients were also administered the multidimensional fatigue inventory, inventory of depressive symptomatology-self-reported, and perceived stress scale at all three time-points and underwent blood sampling prior to RT for gene expression and inflammatory markers previously associated with childhood trauma and behavioral symptoms in breast cancer patients. Eight subjects (40%) had past childhood trauma (CTQ+). Compared to CTQ- patients, CTQ+ patients had significantly higher fatigue, depression, and stress scores before, during, and after RT (p < 0.05); however, RT did not increase these symptoms in either group. CTQ+ patients also exhibited increased baseline expression of gene transcripts related to inflammatory signaling, and baseline inflammatory markers including c-reactive protein, interleukin (IL)-6, and IL-1 receptor antagonist were positively correlated with depression, fatigue, and stress scores in CTQ+ but not CTQ- patients. Childhood trauma was prevalent and was associated with increased symptoms of fatigue, depression, and stress irrespective of RT. Increased symptoms in CTQ+ patients were also associated with baseline inflammatory markers. Treatments targeting childhood trauma and related inflammation may improve symptoms in breast cancer patients. Copyright © 2015 John Wiley & Sons, Ltd.

Only a small percentage of patients with acute stroke are treated with recombinant tissue plasminogen activator (rt-PA). To investigate why patients with right-hemisphere strokes seem at high risk of not receiving rt-PA. This study includes two phases. Phase 1: the authors compared demographic, clinical, and outcome measures between patients with right- and left-hemisphere strokes in the rt-PA Registry of Southwestern Ontario (RSWO); Phase 2: the authors tested the hypotheses generated in Phase 1 using the Registry of the Canadian Stroke Network (RCSN). A multiple logistic analysis was applied to detect independent predictors of rt-PA administration. Phase 1: of 179 rt-PA-treated patients, 39% had right-hemisphere syndrome. Patients with right-hemisphere strokes had a longer hospital stay (15 vs 9 days; p = 0.03). Phase 2: of 990 stroke patients in the RCSN, 505 (51%) had a right- and 485 (49%) a left-hemisphere syndrome. Of 110 rt-PA-treated patients, 37 (34%) had a right-hemisphere syndrome (p = 0.0001). Negative independent predictors of rt-PA administration were right-hemisphere stroke (OR, 0.55; CI: 0.31 to 0.96; p = 0.037), onset-to-emergency department time (OR, 0.99; CI 0.98 to 0.99; p = 0.04), and CNS score (OR, 0.78; CI 0.71 to 0.86; p < 0.0001). Neglect predicted rt-PA administration (OR, 2.32; CI 1.29 to 4.16; p = 0.004). Patients with right-hemisphere strokes are 45% less likely to be treated with recombinant tissue plasminogen activator (rt-PA) compared to patients with left-hemisphere strokes. The presence of neglect confers a twofold increased likelihood of rt-PA administration. Prehospital delay and lack of standardized scores for the neglect syndrome may limit accessibility of patients with right-hemisphere stroke to thrombolysis.

We previously reported results of our on-line microsurgery training program, showing that residents who had access to our website significantly improved their cognitive and technical skills. In this study, we report an objective means for expert evaluators to reliably rate trainees' technical skills under the microscope, with the use of our novel global rating scale. "Microsurgery Essentials" (http://smartmicrosurgery.com) is our on-line training curriculum. Residents were randomly divided into 2 groups: 1 group reviewed this online resource and the other did not. Pre- and post-tests consisted of videotaped microsurgical sessions in which the trainee performed "microsurgery" on 3 different models: latex glove, penrose drain, and the dorsal vessel of a chicken foot. The SMaRT (Stanford Microsurgery and Resident Training) scale, consisting of 9 categories graded on a 5-point Likert scale, was used to assess the trainees. Results were analyzed with ANOVA and Student t test, with P less than 0.05 indicating statistical significance. Seventeen residents participated in the study. The SMaRT scale adequately differentiated the performance of more experienced senior residents (PGY-4 to PGY-6, total average score=3.43) from less experienced junior residents (PGY-1 to PGY-3, total average score=2.10, P<0.0001). Residents who viewed themselves as being confident received a higher score on the SMaRT scale (average score 3.5), compared to residents who were not as confident (average score 2.1) (P<0.001). There were no significant differences in scoring among all 3 evaluators (P>0.05). Additionally, junior residents who had access to our website showed a significant increase in their graded technical performance by 0.7 points when compared to residents who did not have access to the website who showed an improvement of only 0.2 points (P=0.01). Our SMaRT scale is valid and reliable in assessing the microsurgical skills of residents and other trainees. Current trainees are more likely to use self-directed on-line education because of its easy accessibility and interactive format. Our global rating scale can help ensure residents are achieving appropriate technical milestones.

Abstract Laparoscopic colorectal surgery had been widely used for colorectal cancer patient and showed a favorable outcome on the postoperative morbidity rate. We attempted to evaluate physiological status of patients by mean of Estimation of physiologic ability and surgical stress (E-PASS) system and to analyze the difference variation of postoperative morbidity rate of open and laparoscopic colorectal cancer surgery in patients with different physiological status. In total 550 colorectal cancer patients who underwent surgery treatment were included. E-PASS and some conventional scoring systems were reviewed to examine their mortality prediction ability. The preoperative risk score (PRS) in the E-PASS system was used to evaluate the physiological status of patients. The difference of postoperative morbidity rate between open and laparoscopic colorectal cancer surgeries was analyzed respectively in patients with different physiological status. E-PASS had better prediction ability than other conventional scoring systems in colorectal cancer surgeries. Postoperative morbidities were developed in 143 patients. The parameters in the E-PASS system had positive correlations with postoperative morbidity. The overall postoperative morbidity rate of laparoscopic surgeries was lower than open surgeries (19.61% and 28.46%), but the postoperative morbidity rate of laparoscopic surgeries increased more significantly than in open surgery as PRS increased. When PRS was more than 0.7, the postoperative morbidity rate of laparoscopic surgeries would exceed the postoperative morbidity rate of open surgeries. The E-PASS system was capable to evaluate the physiological and surgical risk of colorectal cancer surgery. PRS could assist preoperative decision-making on the surgical method. Colorectal cancer patients who were assessed with a low physiological risk by PRS would be safe to undergo laparoscopic surgery. On the contrary, surgeons should make decisions prudently on the operation method for patient with a high physiological risk. PMID:28816959

A new breast cancer treatment, brachytherapy-based accelerated partial breast radiotherapy (RT), was adopted before long-term effectiveness evidence, potentially increasing morbidity and costs compared with whole breast RT. The aim of this study was to estimate complication rates and RT-specific and 1-year costs for a cohort of female Medicare beneficiaries diagnosed with breast cancer (N = 47 969). We analyzed 2005-2007 Medicare claims using multivariable logistic regression for complications and generalized linear models (log link, gamma distribution) for costs. Overall, 11% (n = 5296) underwent brachytherapy-based RT; 9.4% had complications. Odds of any complication were higher (odds ratio [OR]: 1.62; 95% confidence interval [CI]: 1.49-1.76) for brachytherapy versus whole breast RT, similarly to seroma (OR: 2.85; 95% CI: 1.97-4.13), wound complication/infection (OR: 1.72; 95% CI: 1.52-1.95), cellulitis (OR: 1.48; 95% CI: 1.27-1.73), and necrosis (OR: 2.07; 95% CI: 1.55-2.75). Mean RT-specific and 1-year total costs for whole breast RT were $6375, and $19 917, $4886, and $4803 lower than brachytherapy (P < .0001). Multivariable analyses indicated brachytherapy yielded 76% higher RT costs (risk ratio: 1.76; 95% CI: 1.74-1.78, P < .0001) compared with whole breast RT. Brachytherapy had higher complications and costs before long-term evidence proved its effectiveness. Policies should require treatment registries with reimbursement incentives to capture surveillance data for new technologies. PMID:29502466

Stresses of medical course affects the academic performance as well as physical and psychological health of the students negatively. In the present day scenario every one of us has vulnerability to have psychiatric morbidity. Like other young adults, undergraduate dental students are similarly vulnerable to turmoil due to academic and social stresses, which often hamper the educational achievement. Early detection and treatment of psychological morbidities shorten the suffering leading to less social impairment in long term. The aim of this study was to assess the psychiatric morbidity of dental students and the factors affecting their mental health. This cross sectional, descriptive and correlation study was conducted in North Bengal Dental College, a rural dental college of West Bengal, India. The study sample consisted of a total of 89 dental students. The student enrollment was done by "simple random sampling method". The semi-structured proforma and the General Health Questionnaire (GHQ)-28 were used to collect data and to assess the psychiatric morbidity. Pearson's correlation followed by multivariate linear regression analysis was done to assess the effect of academic achievement, positive and negative event on the GHQ total score. The overall mean GHQ total score in the study population was 5.33, with a SD of 4.85 which was above the cutoff (>4) score. Karl Pearson correlation co-efficient r-values for GHQ total score with 'academic achievement' and 'negative events' score were 0.718 and 0.628 respectively and p-values were 0.001 and 0.001. The poor academic performance and negative events had strong impact on psychological morbidity of dental students. The findings of our study can't be generalized for all undergraduate dental student due to small sample size and non inclusion of many other variables.

Objective Assessments of care including quality assessments adjusted for physiological status should include the development of new morbidities as well as mortalities. We hypothesized that morbidity, like mortality, is associated with physiological dysfunction and could be predicted simultaneously with mortality. Design Prospective cohort study from December 4, 2011 to April 7, 2013. Setting and Patients General and cardiac/cardiovascular pediatric intensive care units at 7 sites. Measurements and Main Results Among 10,078 admissions, the unadjusted morbidity rates (measured with the Functional Status Scale (FSS), and defined as an increase of ≥ 3 from pre-illness to hospital discharge) were 4.6% (site range 2.6% to 7.7%) and unadjusted mortality rates were 2.7% (site range 1.3% – 5.0%). Morbidity and mortality were significantly (p<0.001) associated with physiological instability (measured with the PRISM III score) in dichotomous (survival, death) and trichotomous (survival without new morbidity, survival with new morbidity, death) models without covariate adjustments. Morbidity risk increased with increasing PRISM III scores and then decreased at the highest PRISM III values as potential morbidities became mortalities. The trichotomous model with covariate adjustments included age, admission source, diagnostic factors, baseline FSS and the PRISM III score. The three-level goodness of fit test indicated satisfactory performance for the derivation and validation sets (p>0.20). Predictive ability assessed with the volume under the surface (VUS) was 0.50 ± 0.019 (derivation) and 0.50 ± 0.034 (validation) (versus chance performance = 0.17). Site-level standardized morbidity ratios were more variable than standardized mortality ratios. Conclusions New morbidities were associated with physiological status and can be modeled simultaneously with mortality. Trichotomous outcome models including both morbidity and mortality based on physiological status are suitable for research studies, and quality and other outcome assessments. This approach may be applicable to other assessments presently based only on mortality. PMID:25985385

Background Controversy exists regarding obesity-related injury severity and clinical outcomes after orthopedic trauma. Purpose The purposes of this study were to expand our understanding of the effect of morbid obesity on perioperative and acute care outcomes after acetabular fracture. Methods This was a retrospective review of patients with acetabular fracture after trauma. Non-morbidly obese (BMI < 35 kg/m2) and morbidly obese (BMI ≥ 35 kg/m2; N = 81). Injury severity scores and Glasgow Coma Scale scores (GCS) were collected. Perioperative and acute care outcomes were positioning and operative time, extra fractures, estimated blood loss, complications, hospital charges, ventilator days, transfusions, length of stay (LOS) and discharge destination. Positioning and operative times were longer in morbidly obese patients (p < 0.05). No other differences existed between groups. Conclusions Orthopedic trauma surgeons and care teams can expect similar acute care outcomes in morbidly obese and non-morbidly obese patients with acetabular fracture. PMID:25104886

Purpose: To evaluate the results of salvage radiotherapy (RT) after inadequate surgery in patients with invasive carcinoma of the cervix. Methods and Materials: Between 1996 and 2001, 105 invasive cervical carcinoma patients were treated at our center with external beam RT with or without intracavitary RT after having undergone total/subtotal hysterectomy at outside institutions. Results: The median follow-up was 34 months. The gap between surgery and RT was 23-198 days (median, 80). Clinically visible residual disease was present in 81 patients (77.1%). Total hysterectomy had been done in 82 patients (78%) and subtotal hysterectomy in 23 patients (22%). The 5-yearmore » overall survival, disease-free survival, and pelvic control rates of all patients were 55.2%, 53.3%, and 72.4%, respectively. On univariate analysis, older age, total hysterectomy, hemoglobin level >10 g% before RT, nonsquamous histologic type, use of intracavitary RT, a shorter gap between surgery and RT, and the absence of, or a small volume of, residual disease favorably affected the outcome. The 5-year actuarial rate of late toxicity (Radiation Therapy Oncology Group Criteria) was 19% in the rectum, 4.8% in the bladder, 24.8% in the skin, and 14.3% in the small intestine. Conclusions: Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. Factors such as the use of intracavitary RT, the correction of anemia, and a shorter gap between surgery and RT will enable postoperative RT to achieve acceptable results with minimal morbidity.« less

The aim of this study was to assess quality of life (QoL) and obturator functioning in patients having undergone a maxillectomy as a tumor ablative resection and rehabilitation with a prosthetic obturator. The University of Washington Quality of Life scale version 4 (UW-QoLv4) and the Obturator Functioning Scale (OFS) were used to evaluate the self-reported QoL and obturator functioning. The effects of demographic and treatment variables on QoL were assessed using age, defect size, postoperative radiotherapy (RT), neck dissection, and dentition. The study included 16 men and 13 women with a mean age of 48.8 years. Of the 29 patients, 16 had a Brown Class 2a or smaller defect and 13 had a Brown Class 2b or larger defect. The mean OFS score (P = .004) and the physical (P = .001) and social-emotional function scores (P = .001) of the patients who received postoperative RT were significantly lower than those who did not receive postoperative RT. The subscales for swallowing (P = .008), saliva (P = .001), pain (P = .001), and shoulder function (P = .002) correlated strongly with postoperative RT on the UW-QoL. The subscales for pronunciation (P = .007) and saliva (P = .002) correlated significantly with RT on the OFS. The mean OFS scores were significantly lower for the patients with a Brown Class 2a or smaller defect than for Brown Class 2b or larger (P = .005). Postoperative RT was the strongest variable affecting QoL in patients with maxillectomy and prosthetic obturator reconstruction. The size of the defect slightly influenced the obturator function; however, it did not influence the overall QoL.

Emergency operations for perforated peptic ulcer are associated with a high incidence of postoperative complications. While several studies have investigated the impact of perioperative risk factors and underlying diseases on the postoperative morbidity after abdominal surgery, only a few have analyzed their role in perforated peptic ulcer disease. The purpose of this study was to determine any possible associations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 142 consecutive patients, who underwent surgery for perforated peptic ulcer, at a single institution, between January 2005 and October 2010 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. The postoperative morbidity rate associated with perforated peptic ulcer operations was 36.6% (52/142). Univariate analysis revealed that a long operating time, the open surgical method, age (≥60), sex (female), high American Society of Anesthesiologists (ASA) score and presence of preoperative shock were significant perioperative risk factors for postoperative morbidity. Significant comorbid risk factors included hypertension, diabetes mellitus and pulmonary disease. Multivariate analysis revealed a long operating time, the open surgical method, high ASA score and the presence of preoperative shock were all independent risk factors for the postoperative morbidity in perforated peptic ulcer. A high ASA score, preoperative shock, open surgery and long operating time of more than 150 minutes are high risk factors for morbidity. However, there is no association between postoperative morbidity and comorbid disease in patients with a perforated peptic ulcer.

Purpose: To determine the incidence of pain flare following radiotherapy (RT) for painful bone metastases. Materials and Methods: Patients with bone metastases treated with RT were eligible. Worst pain scores and analgesic consumption were collected before, daily during, and for 10 days after treatment. Pain flare was defined as a 2-point increase in the worst pain score (0-10) compared to baseline with no decrease in analgesic intake, or a 25% increase in analgesic intake with no decrease in worst pain score. Pain flare was distinguished from progression of pain by requiring the worst pain score and analgesic intake return tomore » baseline levels after the increase/flare (within the 10-day follow-up period). Results: A total of 111 patients from three cancer centers were evaluable. There were 50 male and 61 female patients with a median age of 62 years (range, 40-89 years). The primary cancers were mainly breast, lung, and prostate. Most patients received a single 8 Gy (64%) or 20 Gy in five fractions (25%). The overall pain flare incidence was 44/111 (40%) during RT and within 10 days following the completion of RT. Patients treated with a single 8 Gy reported a pain flare incidence of 39% (27/70) and, with multiple fractions, 41% (17/41). Conclusion: More than one third of the enrolled patients experienced a pain flare. Identifying at-risk individuals and managing potential pain flares is crucial to achieve an optimal level of care.« less

While tricuspid valve (TV) operations remain associated with high mortality (∼8-10%), no robust prediction models exist to support clinical decision-making. We developed a preoperative clinical risk model with an easily calculable clinical risk score (CRS) to predict mortality and major morbidity after isolated TV surgery. Multi-state Society of Thoracic Surgeons database records were evaluated for 2,050 isolated TV repair and replacement operations for any etiology performed at 50 hospitals (2002-2014). Parsimonious preoperative risk prediction models were developed using multi-level mixed effects regression to estimate mortality and composite major morbidity risk. Model results were utilized to establish a novel CRS for patients undergoing TV operations. Models were evaluated for discrimination and calibration. Operative mortality and composite major morbidity rates were 9% and 42%, respectively. Final regression models performed well (both P<0.001, AUC = 0.74 and 0.76) and included preoperative factors: age, gender, stroke, hemodialysis, ejection fraction, lung disease, NYHA class, reoperation and urgent or emergency status (all P<0.05). A simple CRS from 0-10+ was highly associated (P<0.001) with incremental increases in predicted mortality and major morbidity. Predicted mortality risk ranged from 2%-34% across CRS categories, while predicted major morbidity risk ranged from 13%-71%. Mortality and major morbidity after isolated TV surgery can be predicted using preoperative patient data from the STS Adult Cardiac Database. A simple clinical risk score predicts mortality and major morbidity after isolated TV surgery. This score may facilitate perioperative counseling and identification of suitable patients for TV surgery. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Post-weaning multi-systemic wasting syndrome (PMWS) causes major economic losses for the English pig industry and severity of clinical signs and economic impact vary considerably between affected farms. We present here a novel approach to quantify severity of PMWS based on morbidity and mortality data and presence of porcine circovirus type 2 (PCV2). In 2008-2009, 147 pig farms across England, non-vaccinating for PCV2, were enrolled in a cross-sectional study. Factor analysis was used to generate variables representing biologically meaningful aspects of variation among qualitative and quantitative morbidity variables. Together with other known variables linked to PMWS, the resulting factors were included in a principal component analysis (PCA) to derive an algorithm for PMWS severity. Factor analysis resulted in two factors: Morbidity Factor 1 (MF1) representing mainly weaner and grower morbidity, and Morbidity Factor 2 (MF2) which mainly reflects variation in finisher morbidity. This indicates that farms either had high morbidity mainly in weaners/growers or mainly in finishers. Subsequent PCA resulted in the extraction of one component representing variation in MF1, post-weaning mortality and percentage of PCV2 PCR positive animals. Component scores were normalised to a value range from 0 to 10 and farms classified into: non or slightly affected farms with a score <4, moderately affected farms with scores 4-6.5 and highly affected farms with a score >6.5. The identified farm level PMWS severities will be used to identify risk factors related to these, to assess the efficacy of PCV2 vaccination and investigating the economic impact of potential control measures.

Vascular warning syndromes constitute a neurological emergency due to their associated high risk of established stroke. At present, there is no strong evidence indicating the best treatment for these patients. The aim of this paper is to describe the function of intravenous rt-PA thrombolysis in the treatment of vascular warning syndromes. We reviewed our hospital records and the literature to find patients with neurologically fluctuating profiles and who underwent intravenous rt-PA thrombolysis. We retrieved 3 cases from our hospital records and 19 from the literature (15 males and 7 females). Mean age was 68.7±9 years (range: 52-84 years). The mean number of episodes before treatment was 4 (range: 2-15 episodes). The maximum NIHSS scores ranged from 6 to 22 in different patients. We obtained 24-hour post-treatment NIHSS scores in 8 cases; of these cases, 6 (75%) had a score of 0, and the other 2 (25%) had a score of 12. The Modified Rankin Score calculated at 3 months of treatment was 0 or 1 in 18 patients (81.8%); these 18 comprised 8 of the 10 patients with lacunar warning syndromes (80%), 6 of the 7 with basilar warning syndromes (85.7%), and 4 of the 5 with fluctuating non-lacunar, non-basilar warning syndromes (80%). Intravenous rt-PA treatment may constitute an effective and safe therapeutic alternative for patients with neurovascular fluctuations. However, well-designed studies are needed to determine the role of intravenous rt-PA thrombolysis in cases of vascular warning syndrome. Copyright © 2013 Sociedad Española de Neurología.

It is becoming increasingly common to incorporate chemotherapy (CT) with radiotherapy (RT) in the treatment of low-grade gliomas (LGGs) after surgical resection. However, there is a lack of literature comparing survival of patients who underwent RT or CT alone. The U.S. National Cancer Data Base was used to identify patients with histologically confirmed, World Health Organization grade 2 gliomas who received either RT alone or CT alone after surgery from 2004 to 2013. Overall survival (OS) was evaluated by Kaplan-Meier analysis, multivariable Cox proportional hazard regression, and propensity-score-matched analysis. In total, 2253 patients with World Health Organization grade 2 gliomas were included, of whom 1466 (65.1%) received RT alone and 787 (34.9%) CT alone. The median OS was 98.9 months for the RT alone group and 125.8 months for the CT alone group. On multivariable analysis, CT alone was associated with a significant OS benefit compared with RT alone (hazard ratio [HR], 0.405; 95% confidence interval, 0.277-0.592; P < 0.001). On subgroup analyses, the survival advantage of CT alone over RT alone persisted across all age groups, and for the subtotal resection and biopsy groups, but not in the gross total resection group. In propensity-score-matched analysis, CT alone still showed significantly improved OS compared with RT alone (HR, 0.612; 95% confidence interval, 0.506-0.741; P < 0.001). Our results suggest that CT alone was independently associated with longer OS compared with RT alone in patients with LGGs who underwent surgery. Copyright © 2018 Elsevier Inc. All rights reserved.

Based on our demonstration of a circadian rhythm in the human oral mucosa cell cycle, with most cells in the G(1) phase in the morning and M phase at night, we hypothesized that morning radiotherapy (RT) would lead to less oral mucositis than afternoon RT. A total of 216 patients were randomized to morning (8-10 AM) vs. afternoon (4-6 PM) RT and stratified by radiation dose, smoking status, and center. Patients receiving primary or postoperative RT alone were eligible. Oral mucositis was scored using the Radiation Therapy Oncology Group (RTOG) criteria and a validated scoring system. Of 205 evaluable patients, 52.9% vs. 62.4% developed RTOG Grade 3 or greater mucositis after morning vs. afternoon RT, respectively (p = 0.17). Morning RT was also associated with significantly less weight loss after 5 months (p = 0.024). In a subgroup of 111 patients treated to a dose of 66-70 Gy in 33-35 fractions, exploratory analyses revealed a significant reduction in Grade 3 or greater mucositis with morning RT (44.6% vs. 67.3%, p = 0.022) and a longer interval to the development of Grade 3 or greater mucositis (median, >7.9 vs. 5.6 weeks, p = 0.033). In 53 patients, who smoked during therapy, a significant reduction was found in Grade 3 or greater mucositis with morning RT (42.9% vs. 76%, p = 0.025). In this proof of principle study, morning RT was associated with significantly less weight loss after 5 months and an apparent reduction in oral mucositis in a subset of patients receiving >/=66 Gy and in patients who smoked during therapy.

The purpose of this study was to examine the impact of moderate-intensity, progressive, upper-body resistance training (RT) on muscle strength and perceived performance of household physical activities (HPA) among women in cardiac rehabilitation. The 10-week, pretest-posttest, experiment randomized women to either usual care (UC) aerobic exercise or RT. Muscle strength for 5 upper-body RT exercises (chest press, shoulder press, biceps curl, lateral row, and triceps extension) was measured using the 1-Repetition Maximum Assessment. The RT group progressively increased weight lifted using 40%, 50%, and 60% of obtained 1-Repetition Maximum Assessment at 3-week intervals. Perceived performance of HPA was measured with the Kimble Household Activities Scale. The RT group (n = 16, mean age 64 +/- 11) significantly increased muscle strength in all 5 exercises in comparison with the UC group (n = 14, mean age 65 +/- 10) (chest press, 18% vs 11%; shoulder press, 24% vs 14%; biceps curl, 21% vs 12%; lateral row, 32% vs 9%; and triceps extension, 28% vs 20%, respectively). By study end, Household Activities Scale scores significantly increased (F = 13.878, P = .001) in the RT group (8.75 +/- 3.19 vs 11.25 +/- 2.14), whereas scores in the UC group decreased (8.60 +/- 3.11 vs 6.86 +/- 4.13). Progressive upper-body RT in women shows promise as an effective tool to increase muscle strength and improve the ability to perform HPA after a cardiac event. Beginning RT early after a cardiac event in a monitored cardiac rehabilitation environment can maximize the strengthening benefit.

Improved access to technology in the radiation therapy (RT) workforce education has resulted in opportunities for innovative patient education methods. This study investigated the impact of a newly developed education tool using the Virtual Environment for Radiotherapy Training (VERT) system on patients' RT knowledge and anxiety. Breast cancer patients were recruited into a control group (CG) (n = 18) who underwent the standard pre-RT education package at a targeted cancer therapy centre, followed by a VERT group (VG) (n = 19). VG patients attended a VERT-based education session detailing RT immobilisation, planning and treatment. All patients completed questionnaires at four time points throughout their treatment, with survey sub-sections on RT knowledge, experience and anxiety. For both groups, anxiety levels were highest at time point 1(T1 after initial radiation oncologist consultation) (CG, 41.2; VG, 43.1), with a gradual decrease observed thereafter at time points before simulation, at the beginning of treatment and at the end of treatment (p > 0.05). The VG's RT knowledge scores were statistically significantly higher than those of the CG scores at all time points following VERT education (p < 0.05). This study reports the high value of VERT breast cancer-targeted education programs in improving RT knowledge and perhaps decreasing patient anxiety. Continued efforts are required to improve patients' accessibility to VERT in Australia, and to better understand the effect of VERT's unique educational features on patients' emotional and physical needs throughout their RT.

This study compares the demographics, injury severity, resource use, and injury patterns of patients involved in railway train-motor vehicle (RT-MV) to motor vehicle-motor vehicle (MV-MV) collisions. Retrospective trauma registry review of 74 RT-MV and 1,931 MV-MV consecutive patients, age more than 14 years, presenting to two Level I trauma centers, January of 1991 to May of 1998. Compared with MV-MV, RT-MV had significantly more males (72% vs. 54%), higher mortality (15% vs. 7%), higher Injury Severity Score (median, 20 vs. 9), longer intensive care unit length of stay (1.7 vs. 0.04 days), and longer hospital length of stay (7.5 vs. 4 days). RT-MV patients had a higher percentage of scalp/facial lacerations; intracranial hemorrhage; hemothorax and pneumothorax; fractures of the rib/sternum, upper extremity, skull, and face; and lung, splenic, and renal injuries. After adjusting for the difference in Injury Severity Score between groups, the only remaining significant group difference was the odds of a scalp/facial laceration. RT-MV collisions are a marker for more severe injuries, but not a different pattern of injury, compared with MV-MV collisions.

Multiple approaches are being studied to enhance the rate of thrombolysis for acute ischemic stroke. Treatment of myocardial infarction with a combination of a reduced-dose fibrinolytic agent and a glycoprotein (GP) IIb/IIIa receptor antagonist has been shown to improve the rate of recanalization versus fibrinolysis alone. The combined approach to lysis utilizing eptifibatide and recombinant tissue-type plasminogen activator (rt-PA) (CLEAR) stroke trial assessed the safety of treating acute ischemic stroke patients within 3 hours of symptom onset with this combination. The CLEAR trial was a National Institutes of Health/National Institute of Neurological Disorders and Stroke-funded multicenter, double-blind, randomized, dose-escalation and safety study. Patients were randomized 3:1 to either low-dose rt-PA (tier 1=0.3 mg/kg, tier 2=0.45 mg/kg) plus eptifibatide (75 microg/kg bolus followed by 0.75 microg/kg per min infusion for 2 hours) or standard-dose rt-PA (0.9 mg/kg). The primary safety end point was the incidence of symptomatic intracerebral hemorrhage within 36 hours. Secondary analyses were performed regarding clinical efficacy. Ninety-four patients (40 in tier 1 and 54 in tier 2) were enrolled. The combination group of the 2 dose tiers (n=69) had a median age of 71 years and a median baseline National Institutes of Health Stroke Scale (NIHSS) score of 14, and the standard-dose rt-PA group (n=25) had a median age of 61 years and a median baseline NIHSS score of 10 (P=0.01 for NIHSS score). Fifty-two (75%) of the combination treatment group and 24 (96%) of the standard treatment group had a baseline modified Rankin scale score of 0 (P=0.04). There was 1 (1.4%; 95% CI, 0% to 4.3%) symptomatic intracranial hemorrhage in the combination group and 2 (8.0%; 95% CI, 0% to 19.2%) in the rt-PA-only arm (P=0.17). During randomization in tier 2, a review by the independent data safety monitoring board demonstrated that the safety profile of combination therapy at the tier 2 doses was such that further enrollment was statistically unlikely to indicate inadequate safety for the combination treatment group, the ultimate outcome of the study. Thus, the study was halted. There was a trend toward increased clinical efficacy of standard-dose rt-PA compared with the combination treatment group. The safety of the combination of reduced-dose rt-PA plus eptifibatide justifies further dose-ranging trials in acute ischemic stroke.

Adults with congenital heart disease in need of heart surgery frequently present with significant comorbidity. Furthermore, additional technical difficulties often related to redo operations increase the risk for postoperative mortality and morbidity. Hence, next to the type of the procedure, additional procedure-dependent and procedure-independent factors have to be considered for risk evaluation. The recently proposed grown-ups with congenital heart disease (GUCH) mortality and morbidity scores account for these additional risk factors. We sought to validate their predictive power in a large population operated in a single centre. Data of all consecutive patients aged 18 years or more, who underwent surgery for congenital heart disease between 2005 and 2016, were collected. Mortality was defined as hospital mortality or mortality within 30 days following surgery. Morbidity was defined as occurrence of one or more of the following complications: renal failure requiring dialysis, neurologic deficit persisting at discharge, atrioventricular block requiring permanent pacemaker implantation, mechanical circulatory support, phrenic nerve injury and unplanned reoperation. The discriminatory power of the GUCH scores was assessed using the area under the receiver operating characteristics curve (c-index, including 95% CI). Eight hundred and twenty-four operations were evaluated. Additional procedure-dependent and procedure-independent factors, as defined in the GUCH scores, were present in 165 patients (20.0%) and 544 patients (66.0%), respectively. Hospital mortality and morbidity was 3.4% and 10.0%, respectively. C-index for GUCH mortality score was 0.809 (0.742-0.877). C-index for GUCH morbidity score was 0.676 (0.619-0.734). We could confirm the good predictive power of the GUCH mortality score for postoperative mortality in a large population of adults with congenital heart disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

To examine the associations of adiposity and aerobic fitness with executive function and math performance in Danish adolescents. Cross-sectional analyses were conducted with data on 525 adolescents attending sixth and seventh grades from 14 schools in the 5 main regions of Denmark. A modified Eriksen flanker task was used to assess inhibitory control, a key aspect of executive function. Academic performance was assessed by a customized math test. Aerobic fitness was assessed by an intermittent shuttle-run test (Andersen test). Body mass index (BMI) was negatively associated with accuracy on incongruent trials during the flanker task (P = .005). A higher BMI was associated with a larger accuracy interference score (P = .01). Similarly, waist circumference (WC) was negatively associated with accuracy on incongruent trials (P = .008). A higher WC was associated with a larger reaction time (RT) interference score (P = .02) and accuracy interference score (P = .009). Higher aerobic fitness was associated with a faster RT on congruent trials (P = .009) and incongruent trials (P = .003). Higher aerobic fitness was associated with a smaller RT interference score (P = .04). Aerobic fitness was positively associated with math score (P < .001). BMI and WC were not associated with math score (P > .05). These results suggest that aerobic fitness is positively associated with both inhibitory control and math performance in adolescents. Adiposity is negatively associated with inhibitory control in adolescents. Adiposity is not associated with math performance. Copyright © 2015 Elsevier Inc. All rights reserved.

Amini, Arya; Jones, Bernard L.; Yeh, Norman

Purpose/Objectives: The addition of whole pelvic (WP) compared with prostate-only (PO) radiation therapy (RT) for clinically node-negative prostate cancer remains controversial. The purpose of our study was to evaluate the survival benefit of adding WPRT versus PO-RT for high-risk, node-negative prostate cancer, using the National Cancer Data Base (NCDB). Methods and Materials: Patients with high-risk prostate cancer treated from 2004 to 2006, with available data for RT volume, coded as prostate and pelvis (WPRT) or prostate alone (PO-RT) were included. Multivariate analysis (MVA) and propensity-score matched analysis (PSM) were performed. Recursive partitioning analysis (RPA) based on overall survival (OS) usingmore » Gleason score (GS), T stage, and pretreatment prostate-specific antigen (PSA) was also conducted. Results: A total of 14,817 patients were included: 7606 (51.3%) received WPRT, and 7211 (48.7%) received PO-RT. The median follow-up time was 81 months (range, 2-122 months). Under MVA, the addition of WPRT for high-risk patients had no OS benefit compared with PO-RT (HR 1.05; P=.100). On subset analysis, patients receiving dose-escalated RT also did not benefit from WPRT (HR 1.01; P=.908). PSM confirmed no survival benefit with the addition of WPRT for high-risk patients (HR 1.05; P=.141). In addition, RPA was unable to demonstrate a survival benefit of WPRT for any subset. Other prognostic factors for inferior OS under MVA included older age (HR 1.25; P<.001), increasing comorbidity scores (HR 1.46; P<.001), higher T stage (HR 1.17; P<.001), PSA (HR 1.81; P<.001), and GS (HR 1.29; P<.001), and decreasing median county household income (HR 1.15; P=.011). Factors improving OS included the addition of androgen deprivation therapy (HR 0.92; P=.033), combination external beam RT plus brachytherapy boost (HR 0.71; P<.001), and treatment at an academic/research institution (HR 0.84; P=.002). Conclusion: In the largest reported analysis of WPRT for patients with high-risk prostate cancer treated in the dose-escalated era, the addition of WPRT demonstrated no survival advantage compared with PO-RT.« less

Purpose Emergency operations for perforated peptic ulcer are associated with a high incidence of postoperative complications. While several studies have investigated the impact of perioperative risk factors and underlying diseases on the postoperative morbidity after abdominal surgery, only a few have analyzed their role in perforated peptic ulcer disease. The purpose of this study was to determine any possible associations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. Materials and Methods In total, 142 consecutive patients, who underwent surgery for perforated peptic ulcer, at a single institution, between January 2005 and October 2010 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. Results The postoperative morbidity rate associated with perforated peptic ulcer operations was 36.6% (52/142). Univariate analysis revealed that a long operating time, the open surgical method, age (≥60), sex (female), high American Society of Anesthesiologists (ASA) score and presence of preoperative shock were significant perioperative risk factors for postoperative morbidity. Significant comorbid risk factors included hypertension, diabetes mellitus and pulmonary disease. Multivariate analysis revealed a long operating time, the open surgical method, high ASA score and the presence of preoperative shock were all independent risk factors for the postoperative morbidity in perforated peptic ulcer. Conclusions A high ASA score, preoperative shock, open surgery and long operating time of more than 150 minutes are high risk factors for morbidity. However, there is no association between postoperative morbidity and comorbid disease in patients with a perforated peptic ulcer. PMID:22500261

Purpose: Given that postprostatectomy recurrence of prostate cancer occurs in 10-40% of patients, the best use of immediate postoperative radiotherapy (RT) in high-risk patients and salvage RT for biochemical recurrence remains a topic of debate. We assessed the levels of evidence (in terms of efficacy, prognostic factors, and toxicity) for the following treatment strategies: immediate postoperative RT alone, salvage RT alone, and the addition of androgen deprivation therapy to the two RT strategies. Methods and Materials: A systematic literature search for controlled randomized trials, noncontrolled trials, and retrospective studies between 1990 and 2008 was performed on PubMed, CancerLit, and MEDLINE.more » Only relevant articles that had appeared in peer-reviewed journals were selected. We report on the levels of evidence (according to the National Cancer Institute guidelines) supporting the various treatment strategies. Results: Immediate postoperative RT improves biochemical and clinical progression-free survival (Level of evidence, 1.ii) but has no significant effect on metastasis-free survival or overall survival. A pathologic review is of particular importance for correctly analyzing the treatment strategies. Low-grade morbidity has been significantly greater in the postoperative groups, but no severe toxicity has been observed. The influence of immediate postoperative RT on postprostatectomy continence appears to be slight; therefore, immediate postoperative RT should be considered in patients with major risk factors for local relapse (Level of evidence, 1.ii). On the basis of extensive retrospective data, salvage RT is effective in biochemical relapse after prostatectomy; some patients with few adverse prognostic factors might also benefit from salvage RT (Level of evidence, 3.ii). The addition of androgen deprivation therapy to immediate postoperative or salvage RT has only been supported by weak, retrospective data (Level of evidence, 3.ii). Conclusion: Prospective randomized trials are needed to compare immediate postoperative RT with salvage RT and to assess the value of androgen deprivation therapy in this setting.« less

Chemoradiotherapy is the treatment of choice for nasopharyngeal carcinoma. Local recurrences are one of the leading causes of death in these patients, and surgical salvage the treatment of choice. Our goal was to evaluate and compare the results of salvage surgery in the treatment of local recurrence of nasopharyngeal carcinomas comparing endoscopic to open approaches. Twenty patients with local recurrence of nasopharyngeal carcinomas underwent surgery: 12 patients underwent open surgery and 8 endoscopic endonasal transpterygoid nasopharyngectomy. One patient was classified as rT1; 3 as rT2;2 as rT3; and 6 as rT4 in the group of open approaches; in the endoscopic series, 2 patients were rT1, 5 rT2 and one rT3. In 3 patients (25%) operated by an open approach (one rT4, one rT3 and one rT2) a complete gross resection was not achieved. Gross total resection was achieved in patients operated by endoscopic surgery. The complication rate in the group operated by an open approach was 92% (5 minor complications, 5 moderate complications, and one serious complication) and in the group that underwent endoscopic surgery all patients had some complication (7 had minor complications and one patient developed a severe complication). Survival at 3 and 5 years was 53% and 42% with the open approach and 100% and 50% with the endoscopic approach, respectively. Endoscopic approaches decrease the morbidity associated with open approaches and allow for favourable oncological control.

Patient and treatment characteristics of patients with head and neck cancer (HNSCC) were correlated with dysphagia scored on swallowing-videofluoroscopy (VFS) and with patient- and physician-scored dysphagia. 63 HNSCC patients treated with radiotherapy (RT) were evaluated at baseline, and 6 and 12 months post-RT. VFS was scored with Penetration Aspiration Scale (PAS) and Swallowing Performance Scale (SPS). Physician- and patient-scored dysphagia were prospectively recorded according to Common Terminology Criteria for Adverse Events scoring system, Radiation Therapy Oncology Group/EORTC scoring system and European Organization for Research and Treatment of Cancer Quality of Life questionnaire (EORTC-QLQ H&N35). Univariable analysis revealed a significant association between tumour-subsite and higher SPS (p = 0.02) and patient-scored dysphagia (p = 0.02) at baseline. At 12 months, tumour-subsite was significantly associated with higher PAS and SPS. Multivariable analysis and pairwise comparison showed that hypopharyngeal cancer and carcinoma of unknown primary  were associated with higher SPS at baseline and at 12 months, respectively (p = 0.03 and p = 0.01). Upfront neck dissection (UFND) was significantly associated with higher SPS and physician-scored dysphagia in univariable analysis at all timepoints. At 12 months, there was also a significant association with higher PAS (p < 0.01) and patient-scored dysphagia (p < 0.01). After multivariable analysis, the association between UFND and higher PAS (p < 0.01) and SPS (p < 0.01) remained significant at 12 months. Hypopharyngeal tumours and carcinoma of unknown primary were related to more dysphagia at baseline and at 12 months, respectively. Furthermore, UFND was associated with more severe dysphagia scored by physicians and patients and on VFS at 12 months. Advances in knowledge: This is the first paper reporting a significant link between UFND and late dysphagia scored with VFS. We advocate abandoning UFND and preserving neck dissection as a salvage option post-RT.

The present study explored the factors effective on colon-related morbidity in patients with penetrating injury of the colon. The medical records of 196 patients were reviewed for variables including age, gender, factor of trauma, time between injury and operation, shock, duration of operation, Penetrating Abdominal Trauma Index (PATI), Injury Severity Score (ISS), site of colon injury, Colon Injury Score, fecal contamination, number of associated intra- and extraabdominal organ injuries, units of transfused blood within the first 24 hours, and type of surgery. In order to determine the independent risk factors, multivariate logistic regression analysis was performed. Gunshot wounds, interval between injury and operation > or =6 hours, shock, duration of the operation > or =6 hours, PATI > or =25, ISS > or =20, Colon Injury Score > or = grade 3, major fecal contamination, number of associated intraabdominal organ injuries >2, number of associated extraabdominal organ injuries >2, multiple blood transfusions, and diversion were significantly associated with morbidity. Multivariate logistic regression analysis showed diversion and transfusion of > or =4 units in the first 24 hours as independent risk factors affecting colon-related morbidity. Diversion and transfusion of > or =4 units in the first 24 hours were determined to be independent risk factors for colon-related morbidity.

There is a lack of population studies evaluating the impact of bariatric surgery (BRS) on all-cause inpatient mortality. We sought to determine the impact of prior BRS on all-cause mortality and healthcare utilization in hospitalized patients. We analyzed the National Inpatient Sample database from 2007 to 2013. Participants were adult (≥ 18 years) inpatients admitted with a diagnosis of morbid obesity or a history of BRS. Propensity score-matched analyses were performed to compare mortality and healthcare resource utilization (hospital length of stay and cost). There were 9,044,103 patient admissions with morbid obesity and 1,066,779 with prior BRS. A propensity score-matched cohort analysis demonstrated that prior BRS was associated with decreased mortality (OR = 0.58; 95% CI [0.54, 0.63]), shorter length of stay (0.59 days; P < 0.001), and lower hospital costs ($2152; P < 0.001) compared to morbid obesity. A subgroup of propensity score-matched analysis among patients with high-risk of mortality (leading ten causes of mortality in morbid obesity) revealed a consistently significant reduction in odds of mortality for patients with prior BRS (OR = 0.82; 95% CI [0.72, 0.92]). Hospitalized patients with a history of BRS have lower all-cause mortality and healthcare resource utilization compared to those who are morbidly obese. These observations support the continued application of BRS as an effective and resource-conscious treatment for morbid obesity.

The study aims to investigate the radiation-induced brain functional alterations in nasopharyngeal carcinoma (NPC) patients who received radiotherapy (RT) using functional magnetic resonance imaging (fMRI) and statistic scale.The fMRI data of 35 NPC patients with RT and 24 demographically matched untreated NPC patients were acquired. Montreal Cognitive Assessment (MoCA) was also measured to evaluate their global cognition performance. Multivariate pattern analysis was performed to find the significantly altered functional connections between these 2 groups, while the linear correlation level was detected between the altered functional connections and the MoCA scores.Forty-five notably altered functional connections were found, which were mainly located between 3 brain networks, the cerebellum, sensorimotor, and cingulo-opercular. With strictly false discovery rate correction, 5 altered functional connections were shown to have significant linear correlations with the MoCA scores, that is, the connections between the vermis and hippocampus, cerebellum lobule VI and dorsolateral prefrontal cortex, precuneus and dorsal frontal cortex, cuneus and middle occipital lobe, and insula and cuneus. Besides, the connectivity between the vermis and hippocampus was also significantly correlated with the attention score, 1 of the 7 subscores of the MoCA.The present study provides new insights into the radiation-induced functional connectivity impairments in NPC patients. The results showed that the RT may induce the cognitive impairments, especially the attention alterations. The 45 altered functional connections, especially the 5 altered functional connections that were significantly correlated to the MoCA scores, may serve as the potential biomarkers of the RT-induced brain functional impairments and provide valuable targets for further functional recovery treatment.

Assessments of care including quality assessments adjusted for physiological status should include the development of new morbidities as well as mortalities. We hypothesized that morbidity, like mortality, is associated with physiological dysfunction and could be predicted simultaneously with mortality. Prospective cohort study from December 4, 2011, to April 7, 2013. General and cardiac/cardiovascular PICUs at seven sites. Randomly selected PICU patients from their first PICU admission. None. Among 10,078 admissions, the unadjusted morbidity rates (measured with the Functional Status Scale and defined as an increase of ≥ 3 from preillness to hospital discharge) were 4.6% (site range, 2.6-7.7%) and unadjusted mortality rates were 2.7% (site range, 1.3-5.0%). Morbidity and mortality were significantly (p < 0.001) associated with physiological instability (measured with the Pediatric Risk of Mortality III score) in dichotomous (survival and death) and trichotomous (survival without new morbidity, survival with new morbidity, and death) models without covariate adjustments. Morbidity risk increased with increasing Pediatric Risk of Mortality III scores and then decreased at the highest Pediatric Risk of Mortality III values as potential morbidities became mortalities. The trichotomous model with covariate adjustments included age, admission source, diagnostic factors, baseline Functional Status Scale, and the Pediatric Risk of Mortality III score. The three-level goodness-of-fit test indicated satisfactory performance for the derivation and validation sets (p > 0.20). Predictive ability assessed with the volume under the surface was 0.50 ± 0.019 (derivation) and 0.50 ± 0.034 (validation) (vs chance performance = 0.17). Site-level standardized morbidity ratios were more variable than standardized mortality ratios. New morbidities were associated with physiological status and can be modeled simultaneously with mortality. Trichotomous outcome models including both morbidity and mortality based on physiological status are suitable for research studies and quality and other outcome assessments. This approach may be applicable to other assessments presently based only on mortality.

Neoadjuvant radiotherapy (RT) for rectal cancer may increase wound complications after oncologic proctectomy. We aimed to assess the relationship between neoadjuvant RT and 30-day wound complications after radical surgery for rectal cancer. We identified rectal cancer patients (International Classification of Diseases, revision-9 [ICD-9] code 154.1) who underwent radical resection, using NSQIP from 2005 to 2010. Patients were stratified into preoperative radiation vs no radiation groups. Our primary outcome was any wound complication. The association between preoperative RT and postoperative wound complication rate was assessed by univariate, multivariable, and propensity score analyses. Of 242,670 colorectal cases, 6,297 patients were included. Of these, 2,476 (39%) received RT within 90 days preoperatively. The RT group, compared with the no RT group, received more chemotherapy within 30 days preoperatively (15.0% vs 2.5%, p < 0.0001), and had less laparoscopic (18.9% vs 25.1%, p < 0.0001) or sphincter-preserving surgery (61.8% vs 67.1%, p < 0.0001). In the univariate analyses, there was no difference in wound complications (19.6% vs 18.7%, p = 0.42) between groups. Similarly, there was no difference in overall complications (29.6% vs 29.8%, p = 0.89), return to operating room (6.7% vs 6.7%, p = 0.96), or length of stay (8.4 vs 8.4 days, p = 0.72) between the RT and no RT groups, respectively. The mortality rate in the RT group was lower on univariate analysis (0.7% vs 1.4%, p = 0.008), but was not significantly different in the multivariable analyses. Multivariable and propensity score analyses were consistent with the lack of association between preoperative RT and postoperative wound complications. Neoadjuvant radiotherapy does not appear to be an independent risk factor for wound complications after radical surgery for rectal cancer. Copyright © 2016 American College of Surgeons.

Infectious diseases are common causes of significant morbidity and mortality events of wild aquatic birds (WABs) worldwide. Reports of Australian events are infrequent. A 3-yr passive surveillance program investigating the common causes of morbidity and mortality of WABs was conducted at Billabong Sanctuary near Townsville, North Queensland, from April 2007 to March 2010. Forty-two carcasses were obtained and evaluated by clinico-pathologic, histologic, bacteriologic, and virologic (molecular) examinations. Morbidity and mortality were sporadic and more commonly observed in chicks and juvenile birds in April than other months of the year. Morbid birds were frequently unable to walk. Hemorrhagic lesions and infiltration of lymphocytes in various organs were the most common findings in dead birds. Identified bacterial diseases that could cause bird mortality were colibacillosis, pasteurellosis, and salmonellosis. Salmonella serotypes Virchow and Hvittingfoss were isolated from an Australian white ibis (Threskiornis molucca) chick and two juvenile plumed whistling ducks (Dendrocygna eytoni) in April 2007. These strains have been previously isolated from humans in North Queensland. A multiplex real time reverse transcriptase-PCR (rRT-PCR) detected Newcastle disease viral RNA (class 2 type) in one adult Australian pelican (Pelecanus conspicillatus) and a juvenile plumed whistling duck. No avian influenza viral RNA was detected from any sampled birds by the rRT-PCR for avian influenza. This study identified the public health importance of Salmonella in WABs but did not detect the introduction of the high pathogenicity avian influenza H5N1 virus in the population. A successful network was established between the property owner and the James Cook University research team through which dead birds, with accompanying information, were readily obtained for analysis. There is an opportunity for establishing a long-term passive disease surveillance program for WABs in North Queensland, an important region in Australian biosecurity, thus potentially significantly benefitting public health in the region and the country.

We have analyzed reverse transcriptase (RT) region of HIV-1 pol gene from 97 HIV-infected children who were identified as failing first-line therapy that included first-generation non-nucleoside RT inhibitors (Nevirapine and Efavirenz) for at least 6 months. We found that 54% and 65% of the children had genotypically predicted resistance to second-generation non-nucleoside RT inhibitors drugs Etravirine (ETR) and Rilpivirine, respectively. These cross-resistance mutations may compromise future NNRTI-based regimens, especially in resource-limited settings. To complement these investigations, we also analyzed the sequences in Stanford database, Monogram weighted score, and DUET weighted score algorithms for ETR susceptibility and found almost perfect agreement between the three algorithms in predicting ETR susceptibility from genotypic data.

Purpose: The purpose of this study was to assess the association between positive post-radiation therapy (RT) biopsy results and subsequent clinical outcomes in males with localized prostate cancer. Methods and Materials: Radiation Therapy Oncology Group study 94-08 analyzed 1979 males with prostate cancer, stage T1b-T2b and prostate-specific antigen concentrations of ≤20 ng/dL, to investigate whether 4 months of total androgen suppression (TAS) added to RT improved survival compared to RT alone. Patients randomized to receive TAS received flutamide with luteinizing hormone releasing hormone (LHRH) agonist. According to protocol, patients without evidence of clinical recurrence or initiation of additional endocrine therapy underwent repeatmore » prostate biopsy 2 years after RT completion. Statistical analysis was performed to evaluate the impact of positive post-RT biopsy results on clinical outcomes. Results: A total of 831 patients underwent post-RT biopsy, 398 were treated with RT alone and 433 with RT plus TAS. Patients with positive post-RT biopsy results had higher rates of biochemical failure (hazard ratio [HR] = 1.7; 95% confidence interval [CI] = 1.3-2.1) and distant metastasis (HR = 2.4; 95% CI = 1.3-4.4) and inferior disease-specific survival (HR = 3.8; 95% CI = 1.9-7.5). Positive biopsy results remained predictive of such outcomes after correction for potential confounders such as Gleason score, tumor stage, and TAS administration. Prior TAS therapy did not prevent elevated risk of adverse outcome in the setting of post-RT positive biopsy results. Patients with Gleason score ≥7 with a positive biopsy result additionally had inferior overall survival compared to those with a negative biopsy result (HR = 1.56; 95% CI = 1.04-2.35). Conclusions: Positive post-RT biopsy is associated with increased rates of distant metastases and inferior disease-specific survival in patients treated with definitive RT and was associated with inferior overall survival in patients with high-grade tumors.« less

Radioimmunoscintigraphy (RIS) has the potential to demonstrate early recurrences after prostatectomy and might be useful in selecting patients for salvage radiotherapy (RT). A total of 82 patients with adenocarcinoma of the prostate were treated with salvage RT between 1988 and 2005, for an elevated prostate-specific antigen (PSA) level after prostatectomy. Of the 82 patients, 32% had Gleason score 6 or less disease, 54% Gleason score 7 disease, 70% had Stage pT3 disease, 55% had positive margins, and 5% had pathologic lymph node involvement. The median pre-RT PSA level was 0.63 ng/mL. Of the 82 patients, 47 (57%) had a pre-RT RIS (ProstaScint) scan, which was used for both patient selection and target delineation. The RT regimen was a median dose of 66 Gy to the prostate bed. Also, 64% received androgen deprivation therapy. Biochemical failure was defined as a PSA level >0.1 ng/mL and increasing. Patients with a pre-RT RIS scan had a lower preoperative PSA level (p = 0.0240) and shorter follow-up (p = 0.0221) than those without RIS. With a median follow-up of 44 months, the biochemical control rate was 56% at 3 years and 48% at 5 years. Margin status was the only factor associated with biochemical control on univariate (p = 0.0055) and multivariate (p = 0.0044) analysis. Patients who had prostate bed-only uptake on RIS (n = 38) did not have improved outcomes, with biochemical control rates of 51% at 3 years and 40% at 5 years. Patients treated with salvage RT had modest responses. Patients who were selected for treatment with RIS did not have better biochemical outcomes. Our results indicated that patients with positive margins were most likely to benefit from salvage RT.

Purpose: To evaluate 2 specific radiation schedules, each combined with temozolomide (TMZ), assessing their efficacy and safety in patients aged ≥65 years with newly diagnosed glioblastoma (GBM). Methods and Materials: Patients aged ≥65 years with Karnofsky performance status (KPS) ≥60 who received either standard (60 Gy) or short-course (40 Gy) radiation therapy (RT) with concomitant and adjuvant TMZ between June 2004 and October 2013 were retrospectively analyzed. A propensity score analysis was executed for a balanced comparison of treatment outcomes. Results: A total of 127 patients received standard RT-TMZ, whereas 116 patients underwent short-course RT-TMZ. Median overall survival and progression-free survival times were similar: 12 monthsmore » and 5.6 months for the standard RT-TMZ group and 12.5 months and 6.7 months for the short-course RT-TMZ group, respectively. Radiation schedule was associated with similar survival outcomes in either unadjusted or adjusted analysis. O{sup 6}-methylguanine-DNA methyltransferase promoter methylation was the most favorable prognostic factor (P=.0001). Standard RT-TMZ therapy was associated with a significant rise in grade 2 and 3 neurologic toxicity (P=.01), lowering of KPS scores during the study (P=.01), and higher posttreatment dosing of corticosteroid (P=.02). Conclusions: In older adults with GBM, survival outcomes of standard and short-course RT-TMZ were similar. An abbreviated course of RT plus TMZ may represent a reasonable therapeutic approach for these patients, without loss of survival benefit and acceptable toxicity.« less

It has been proven that physical morbidity is related to psychiatric illness. Some physical illnesses are more related to psychiatric morbidity compared to others. Epilepsy is considered one of them, as patients who suffer from epilepsy has disturbances of consciousness and this leads to a variety of psychological disturbance in addition to the psychological and social impact of the illness. To identify risk factors and psychiatric morbidity in epilepsy, in order to try to manage it and improve outcome of this illness and enhance quality of life. Patients who were referred to the department of Neurology at Mosul Teaching hospital from primary care centres between October 2012 and February 2013 and consented to participate in the study, were checked and if they fulfilled the criteria for the diagnosis of epilepsy, they were interviewed and their sociodemographic data were recorded, the hospital anxiety and depression questionnaire (HAD) was administered. Results were input in a computer programme and software statistical programme Minitab version 14.1 was utilised to analyse these data. The whole sample was 100 patients. 55 females and 45 males were included. Mean age was 30 years. Mean duration of illness was 5.5 years. Mean HAD score was 17. Male patients were a little bit older but there was no statistically significant difference compared to females and they both scored similar HAD score. There was no difference between urban and rural population with regards to HAD score. The results showed statistically significant correlation between age and duration of the illness and HAD score. The present study showed that there is a correlation between epilepsy and psychiatric morbidity. It has confirmed that females are more affected compared to males, which is expected as compared to the general population. It has also confirmed that psychiatric morbidity is positively related to epilepsy as it showed that the duration of illness has increased the psychiatric morbidity. Psychiatric morbidity is a neglected area in the management and care of physical illnesses, especially, epilepsy, where patients may get stigmatised and traumatised in the society. They may live in constant fear of having a fit. Assessing and managing the psychiatric morbidity of such patients will be reflected on the outcome of the illness and improve the quality of life of patients.

Maternal morbidity is increasing in the United States. Our objectives were to examine whether a labor and delivery (L&D) provider model with regular maternal-fetal medicine (MFM) coverage decreases the rates of maternal morbidity during delivery hospitalizations and has an impact on obstetrician-gynecologist residents' perceptions of safety and education. We performed a retrospective cohort study to compare the rates of maternal morbidity before and after the implementation of an MFM-centered coverage model on L&D. Outcomes were identified using International Classification of Diseases, ninth revision, codes. The primary outcome was a composite of severe maternal morbidity. Additionally, obstetrician-gynecologist residents completed an anonymous survey asking them to compare coverage models, and their Council on Resident Education in Obstetrics and Gynecology examination scores were compared. Data from 4715 deliveries were included. There were no differences in composite morbidity or individual adverse outcomes. Most residents (81.3%) preferred the new provider model, with median 5-point Likert scores indicating perceived increases in safety and education. Mean Council on Resident Education in Obstetrics and Gynecology scores improved in the 18 residents exposed to both models. Although the MFM-centered provider model appears to have had a positive impact on residents' perceptions of safety and education, it was not associated with significant changes in severe maternal morbidity.

The study of Human immunodeficiency virus (HIV) in humans and animal models in last 31 years suggested that it is a causative agent of AIDS. This causes serious pandemic public health concern globally. It was reported that the HIV-1 reverse transcriptase (RT) played a critical role in the life cycle of HIV. Therefore, inhibition of HIV-1RT enzyme is one of the major and potential targets in the treatment of AIDS. The enzyme (HIV-1RT) was successfully targeted by non nucleotide reverse transcriptase inhibitors (NNRTIs). But frequent application of NNRTIs led drug resistance mutation on HIV infections. Therefore, there is a need to search new NNRTIs with appropriate pharmacophores. For the purpose, a virtually screened 3D model of unliganded HIV-1RT (1DLO) was explored. The unliganded HIV-1RT (1DLO) was docked with 4-thiazolidinone and its derivatives (ChemBank Database) by using AutoDock4. The best seven docking solutions complex were selected and analyzed by Ligplot. The analysis showed that derivative (5E)-3-(2- aminoethyl)-5-(2- thienylmethylene)-1, 3-thiazolidine-2, 4-dione (CID 3087795) has maximum potential against unliganded HIV-1RT (1DLO). The analysis was done on the basis of scoring and binding ability. The derivative (5E)-3-(2- aminoethyl)-5-(2- thienylmethylene)-1, 3-thiazolidine-2, 4-dione (CID 3087795) indicated minimum energy score and highest number of interactions with active site residue and could be a promising inhibitor for HIV-1 RT as Drug target.

Nonalcoholic steatohepatitis (NASH) is common in morbidly obese persons. Liver biopsy is diagnostic but technically challenging in such individuals. This study was undertaken to develop a clinically useful scoring system to predict the probability of NASH in morbidly obese persons, thus assisting in the decision to perform liver biopsy. Consecutive subjects undergoing bariatric surgery without evidence of other liver disease underwent intraoperative liver biopsy. The outcome was pathologic diagnosis of NASH. Predictors evaluated were demographic, clinical, and laboratory variables. A clinical scoring system was constructed by rounding the estimated regression coefficients for the independent predictors in a multivariate logistic model for the diagnosis of NASH. Of 200 subjects studied, 64 (32%) had NASH. Median body mass index was 48 kg/m(2) (interquartile range, 43-55). Multivariate analysis identified six predictive factors for NASH: the diagnosis of hypertension (odds ratio [OR], 2.4; 95% confidence interval [CI], 1-5.6), type 2 diabetes (OR, 2.6; 95% CI, 1.1-6.3), sleep apnea (OR, 4.0; 95% CI, 1.3-12.2), AST > 27 IU/L (OR, 2.9; 95% CI, 1.2-7.0), alanine aminotransferase (ALT) > 27 IU/L (OR, 3.3; 95% CI, 1.4-8.0), and non-Black race (OR, 8.4; 95% CI, 1.9-37.1). A NASH Clinical Scoring System for Morbid Obesity was derived to predict the probability of NASH in four categories (low, intermediate, high, and very high). The proposed clinical scoring can predict NASH in morbidly obese persons with sufficient accuracy to be considered for clinical use, identifying a very high-risk group in whom liver biopsy would be very likely to detect NASH, as well as a low-risk group in whom biopsy can be safely delayed or avoided.

The Accreditation Council for Graduate Medical Education Milestone Project for general surgery provided a more robust method for developing and tracking residents' competence. This framework enhanced systematic and progressive development of residents' competencies in surgical quality improvement. A 22-month interactive, educational program based on resident-specific surgical outcomes data culminated in a quality improvement project for postgraduate year 4 surgery residents. Self- assessment, quality knowledge test, and resident-specific American College of Surgeons National Surgical Quality Improvement Program Quality In-Training Initiative morbidity were compared before and after the intervention. Quality in-training initiative morbidity decreased from 25% (82/325) to 18% (93/517), p = 0.015 despite residents performing more complex cases. All participants achieved level 4 competency (4/4) within the general surgery milestones improvement of care, practice-based learning and improvement competency. Institutional American College of Surgeons National Surgical Quality Improvement Program general surgery morbidity improved from the ninth to the sixth decile. Quality assessment and improvement self-assessment postintervention scores (M = 23.80, SD = 4.97) were not significantly higher than preintervention scores (M = 19.20, SD = 5.26), p = 0.061. Quality Improvement Knowledge Application Tool postintervention test scores (M = 17.4, SD = 4.88), were not significantly higher than pretest scores (M = 13.2, SD = 1.92), p = 0.12. Sharing validated resident-specific clinical data with participants was associated with improved surgical outcomes. Participating fourth year surgical residents achieved the highest score, a level 4, in the practice based learning and improvement competency of the improvement of care practice domain and observed significantly reduced surgical morbidity for cases in which they participated.

The objective of this study was: 1) to compare health-related quality of life (HRQoL) scores of breast cancer survivors to matched controls; and 2) to examine the relative impact (explained variance) of the type and number of co-morbidities on HRQoL. Data from the KARMA project was used in this cross-sectional study. For each woman diagnosed with breast cancer (n = 2552) there were two healthy age- and geographically matched females (n = 5104). Breast cancer survivors were categorized according to time since diagnosis: recently diagnosed (0-1 year), short- (2-5 years), mid- (6-10 years), and long-term survivors (> 10 years). Women completed a questionnaire addressing demographics (age, educational level, and geographical location), lifestyle factors (body mass index (BMI) and smoking), co-morbidities, and HRQoL. The difference in explained variance in six HRQoL-domains between demographics, lifestyle factors, and co-morbidity in women with breast cancer and matched controls was examined by hierarchical regression analyses. Women recently diagnosed (n = 63), reported the worst HRQoL followed by short-term survivors (2-5 years, n = 863). Thereafter, HRQoL scores further improved (6-10 years, n = 726), and were comparable to healthy females after 10 years (n = 893). Co-morbidity has a negative impact on HRQoL, which increased with time after diagnosis. Cardiovascular disease and depression were the strongest associates. Breast cancer survivors report clinically significant improvement in HRQoL scores six years after diagnosis. Co-morbidity has a negative impact on HRQoL, which increases with time after diagnosis, even though the number of co-morbidities remains stable. In long-term survivors there should be increasing awareness of co-morbidity and its impact on HRQoL.

To study risk of birth asphyxia and related morbidity among term singletons born after medically assisted reproduction (MAR). Population cohort study. Not applicable. A total of 1,953,932 term singleton pregnancies selected from a national registry for 1999-2011. None. Primary outcome Apgar score <4; secondary outcomes Apgar score <7, intrauterine fetal death, perinatal mortality, congenital anomalies, small for gestational age, asphyxia related morbidity, and cesarean delivery. The risks of birth asphyxia and related morbidity were calculated in women who conceived either through MAR or spontaneously (SC), with a subgroup analysis for in vitro fertilization (IVF). An additional propensity score matching analysis was performed with matching on multiple maternal baseline covariates (maternal age, ethnicity, socioeconomic status, parity, year of birth, and preexistent diseases). Each MAR pregnancy was matched to three SC controls. Relative to SC, the MAR singletons had an increased risk of adverse neonatal outcomes including Apgar score <4 (adjusted odds ratio [OR] 1.29; 95% CI, 1.14-1.46) and intrauterine fetal death (adjusted OR 1.61; 95% CI, 1.35-1.91). After propensity score matching, the risk of an Apgar score <4 was comparable between MAR and SC singletons (OR 0.99; 95% CI, 0.87-1.14). Cesarean delivery for both fetal distress and nonprogressive labor occurred more among MAR pregnancies compared with SC pregnancies. Term singletons conceived after MAR have an increased risk of morbidity related to birth asphyxia. Because this is mainly due to maternal characteristics, obstetric caregivers should be aware that the increased rates of cesareans reflect the behavior of women and physicians rather than increased perinatal complications.

Health-related quality of life (HRQOL) is influenced by the disease state, associated complications and their management. In patients with liver cirrhosis co-morbidity, severity of liver disease and their complications are likely to affect the QOL. The aim of the study was to determine the factors that are likely to influence the domains of HRQOL using SF-36 in patients with liver cirrhosis. For the study, 149 patients with liver cirrhosis were compared with age-gender matched healthy controls for physical and mental components of SF-36 score and the effects of age, co-morbidity severity of liver disease and complications of liver cirrhosis on HRQOL were assessed using the same questionnaire. Results of the study showed that except for body pain, all the patients had a significantly low individual and composite domain score (p-value <0.0001) compared to age-gender matched controls. Patients below 45 years, Child-Turcotte-Pugh (CTP) C, a high model for end-stage liver disease (MELD) and higher rates of complication had low scores for body pain (KW p <0.005) and those above 55 years, for physical function (p <0.05). Both the physical components had a major impact on mental composite score (MCS) (KW p <0.05). Co-morbidity that included diabetes, hypertension and hypothyroid states in various combinations had no effect on SF-36 scores while co-morbid conditions like musculoskeletal pain, arthralgia etc. affected physical domains (physical function, body pain and role physical) and physical component score (PCS) (KW p <0.01 to <0.0001). By linear regression, MELD had a direct and significant association with overall PCS and mental component score (MCS).

Patients with head and neck cancer (HNC) experience involuntary weight loss that has a negative impact on physical function, morbidity, and survival. The objective of the current study was to evaluate the feasibility of an exercise and nutrition intervention during radiotherapy (RT) compared with after RT, and to examine preliminary effects on skeletal muscle mass. Patients with HNC were randomized to an exercise and nutrition intervention during RT (EN-DUR) or after RT (EN-AF). The EN-DUR intervention was conducted at a hospital and the EN-AF intervention took place at a rehabilitation center. The interventions consisted of progressive resistance training (PRT) and oral nutritional supplements (ONS). Feasibility outcomes were tracked weekly and muscle mass was measured by computed tomography scans before and after RT and at 2 months follow-up. Of the 50 eligible patients, 41 (82%) agreed to participate. 90% of patients completed the EN-DUR intervention and the adherence to PRT and ONS was 81% and 57%, respectively. 52% of patients attended the EN-AF intervention and adherence to PRT and ONS was 94% and 76%, respectively. The EN-DUR demonstrated a trend toward mitigating loss of muscle mass during RT and the EN-AF demonstrated a similar trend after RT. No difference in muscle mass was detected between the groups from baseline to week 14. An exercise and nutrition intervention is feasible for patients with HNC during RT, and the intervention is potentially effective in mitigating loss of muscle mass both during and after RT. Future trials should assess the feasibility and effects of extended interventions during and after treatment. Cancer 2017;123:4440-8. © 2017 American Cancer Society. © 2017 American Cancer Society.

Patterns of postoperative radiotherapy (RT) use in prostate cancer (PCa) after the publication of major randomized trials have not been well characterized. To describe patterns of postoperative RT use after radical prostatectomy (RP) in patients with adverse pathologic features in the United States. Retrospective analysis of 97 270 patients with PCa diagnosed between 2005 and 2011 whose presentation and outcomes were recorded in the National Cancer Data Base. Temporal changes in receipt of postoperative RT and factors associated with receipt of this treatment using the Cochran-Armitage trend test and multiple logistic regression, respectively. Between 2005 and 2011, receipt of postoperative RT decreased steadily from 9.1% to 7.3% (ptrend<0.001). Use of RT with or without androgen deprivation therapy monotonically decreased with advancing age from 8.5% in patients aged 18-59 yr to 6.8% in patients aged 70-79 yr (ptrend<0.001). Receipt of RT was higher at community cancer programs compared with teaching/research centers (14% vs 7.3%; odds ratio [OR]: 2.16; p<0.001), in those with pT3-4 disease and positive margins compared with those with pT3-4 and negative margins (17% vs 5.9%; OR: 2.89; p<0.001), and in patients with a Gleason score of 8-10 compared with those with a Gleason score of 2-6 (17% vs 4.2%; OR: 3.50; p<0.001). Limitations include lack of postprostatectomy prostate-specific antigen level. Postoperative RT use for localized PCa in patients with adverse pathologic features is declining in the United States. In this report, we show that use of postoperative radiotherapy in patients with prostate cancer with adverse pathologic features is declining. Patients treated at community cancer programs, those with locally advanced disease and positive margins, and those with a high Gleason score were more likely to receive postoperative radiotherapy.

Purpose: Radiation therapy (RT) is an effective method of palliating painful bone metastases and can improve function and reduce analgesic requirements. In advanced cancer patients, quality of life (QOL) is the primary outcome of interest over traditional endpoints such as survival. The purpose of our study was to compare bone metastasis-specific QOL scores among patients who responded differently to palliative RT. Methods and Materials: Patients receiving RT for bone metastases across 6 countries were prospectively enrolled from March 2010-January 2011 in a trial validating the QLQ-BM22 and completed the QLQ-BM22 and the core measure (QLQ-C30) at baseline and after 1more » month. Pain scores and analgesic intake were recorded, and response to RT was determined according to the latest published guidelines. The Kruskal-Wallis nonparametric and Wilcoxon rank sum tests compared changes in QOL among response groups. A Bonferroni-adjusted P<.003 indicated statistical significance. Results: Of 79 patients who received palliative RT, 59 were assessable. Partial response, pain progression, and indeterminate response were observed in 22, 8, and 29 patients, respectively; there were no patients with a complete response. Patients across all groups had similar baseline QOL scores apart from physical functioning (patients who progressed had better initial functioning). One month after RT, patients who responded had significant improvements in 3 of 4 QLQ-BM22 domains (painful site, P<.0001; painful characteristic, P<.0001; and functional interference, P<.0001) and 3 QLQ-C30 domains (physical functioning, P=.0006; role functioning, P=.0026; and pain, P<.0001). Patients with progression in pain had significantly worse functional interference (P=.0007) and pain (P=.0019). Conclusions: Patients who report pain relief after palliative RT also have better QOL with respect to bone metastasis-specific issues. The QLQ-BM22 and QLQ-C30 are able to discriminate among patients with varying responses and are recommended for use in future bone metastasis clinical trials.« less

Radical prostatectomy (RP) is associated with anejaculation, which for some men is a source of bother and sexual dissatisfaction. Clinical experience has shown us some men after pelvic radiation therapy (RT) also experience anejaculation. This analysis was conducted to define the ejaculation profiles of men after RT for prostate cancer (PCa). As a routine part of the sexual health evaluation for post-RT patients, men provided information regarding their ejaculatory function and orgasm. Analysis was conducted of a sexual medicine database reviewing demographic data, PCa factors, erectile, ejaculatory, and orgasmic function. Men with prior history of RP, cryotherapy, focal therapies, and androgen deprivation therapy (ADT) were excluded. Patients completed the International Index of Erectile Function (IIEF) questionnaire at follow-up visits commencing with the first posttreatment visit and specific attention was paid to the IIEF orgasm domain. Three hundred and sixty-four consecutive patients were included. Two hundred and fifty-two patients had external beam, and 112 patients had brachytherapy (BT). Mean age was 64 ± 11 (42-78) years and mean follow-up after RT was 6 ± 4.5 years. Mean prostate size at time of RT was 42 ± 21 g. Of the entire population, 72% lost the ability to ejaculate in an antegrade fashion after prostate RT by their last visit. The proportion experiencing anejaculation at 1, 3, and 5 years after RT was 16%, 69%, and 89%, respectively. For men with at least two IIEF questionnaires completed, the orgasm domain scores decreased dramatically over the follow-up period; orgasm domain scores (0-10): <12 months post-RT 7.4, 13-24 months 5.4, 25-36 months 3.2, >36 months 2.8 (P < 0.01). Multivariable analysis identified several factors predictive of failure to ejaculate: older age, ADT, RT dose > 100 Gy, and smaller prostates at the time of RT. The vast majority of men after prostate RT will experience anejaculation and should be counseled accordingly prior to undergoing therapy. We have identified predictive factors. © 2013 International Society for Sexual Medicine.

Cardiac injury is one of the complications of cancer treatment. This study aimed to investigate the relationships between the types of radiotherapy of the chest (RT), chemotherapy (CT), cancer surgery (CS) and endocrine therapy (ET), and the presence of heart disease, and their associations with the serum level of N-terminal pro-B-type natriuretic peptide (NT-proBNP). A consecutive series of 374 patients with cancer who were referred because of symptoms suggestive of heart or lung disease prospectively underwent a diagnostic workup. The prevalence of heart disease was 36.9%. RT administered before 1995 (n = 19) was associated with both increased odds of heart disease [adjusted odds ratio 10.3, 95% confidence interval 3.1-34.0] and higher ln-transformed NT-proBNP values (p < 0.01) compared to the control group (no RT or RT for right-sided breast cancer from 1995 onwards; n = 311). Anthracycline-treated patients (n = 54) had higher adjusted values for ln(NT-proBNP) compared to the control group (no CT; n = 243; p < 0.01) but no increased odds of heart disease. While pre-1995 RT and anthracycline-containing CT were associated with cardiac effects, there was no evidence that RT using modern cardioprotective techniques, CT in the absence of anthracyclines, CS or ET had detrimental effects on the heart.

To the authors' knowledge, health-related quality of life (HRQOL) outcomes are not well described in patients with medulloblastoma. The use of proton radiotherapy (RT) may translate into an improved HRQOL. In the current study, the authors report long-term HRQOL in patients with proton-treated pediatric medulloblastoma. The current study was a prospective cohort HRQOL study of patients with medulloblastoma who were treated with proton RT and enrolled between August 5, 2002, and October 8, 2015. Both child report and parent-proxy report Pediatric Quality of Life Inventory (PedsQL) surveys were collected at baseline during RT and annually thereafter (score range on surveys of 0-100, with higher scores indicating better HRQOL). Patients were dichotomized by clinical/treatment variables and subgroups were compared. Mixed-model analysis was performed to determine the longitudinal trajectory of PedsQL scores. The Student t test was used to compare long-term HRQOL measures with published means from a healthy child population. Survey data were evaluable for 116 patients with a median follow-up of 5 years (range, 1-10.6 years); the median age at the time of diagnosis was 7.6 years (range, 2.1-18.1 years). At baseline, children reported a total core score (TCS) of 65.9, which increased by 1.8 points annually (P<.001); parents reported a TCS of 59.1, which increased by 2.0 points annually. Posterior fossa syndrome adversely affected baseline scores, but these scores significantly improved with time. At the time of last follow-up, children reported a TCS of 76.3, which was 3.3 points lower than that of healthy children (P = .09); parents reported a TCS of 69, which was 11.9 points lower than that of parents of healthy children (P<.001). Increased follow-up time from diagnosis correlated with improved HRQOL scores. HRQOL scores appear to increase over time after treatment in children treated with proton RT for medulloblastoma but remain lower compared with those of parent-proxy reports as well as published means from a healthy normative sample of children. Additional follow-up may translate into continued improvements in HRQOL. Cancer 2018. © 2018 American Cancer Society. © 2018 American Cancer Society.

Effect of Smoking During Radiotherapy, Respiratory Insufficiency, and Hemoglobin Levels on Outcome in Patients Irradiated for Non-Small-Cell Lung Cancer

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rades, Dirk; Setter, Cornelia M.S.; Schild, Steven E.

Purpose: To investigate the effect of smoking during radiotherapy (RT), respiratory insufficiency before RT, hemoglobin levels during RT, and additional factors on overall survival, locoregional control (LRC), and metastasis-free survival in non-small-cell lung cancer patients. Methods and Materials: The following factors were investigated in 181 patients who underwent RT for non-small-cell lung cancer: age, gender, Karnofsky performance score, histologic type, grade, T/N stage, American Joint Committee on Cancer stage, surgery, chemotherapy, respiratory insufficiency before RT, pack-years, smoking during RT, and hemoglobin levels during RT. Additionally, in the 129 patients who did not undergo surgery, the effect of the equivalent dosemore » in 2-Gy fractions (EQD2) (<60 Gy vs. 60 Gy vs. >60 Gy) on outcome was investigated. Results: On multivariate analysis, improved overall survival was associated with a lower T stage (p = 0.004), lower N stage (p 0.040), surgery (p = 0.010), and no respiratory insufficiency (p = 0.023). A Karnofsky performance score >70 achieved borderline significance (p = 0.056). Improved LRC was associated with a lower T stage (p = 0.007) and no smoking during RT (p = 0.029). Improved metastasis-free survival was associated with lower T stage (p < 0.001) and lower N stage (p < 0.001). In those patients who did not undergo surgery, an EQD2 of {>=}60 Gy was associated with a better outcome than an EQD2 of <60 Gy. Furthermore, an EQD2 >60 Gy resulted in better LRC than did an EQD2 of {<=}60 Gy. Conclusions: Smoking during RT had a significant effect on LRC, but we did not find that hemoglobin levels or respiratory insufficiency significantly affected LRC or metastasis-free survival in our patient population. Furthermore, our data suggest a dose-effect relationship in those patients who did not undergo surgery.« less

Phosphatidylserine (PS) may attenuate the adverse effects of physical fatigue. Therefore, we investigated the effects of a multi-ingredient supplement containing 400 mg/d PS and 100 mg/d caffeine (supplement [SUP]) for 2 weeks on measures of cognitive function (CF), reaction time (RT), and mood (MD) following an acute exercise stress. It is hypothesized that PS will maintain preexercise CF and RT scores, while attenuating postexercise fatigue. Participants completed 2 acute bouts of resistance exercise (T1 and T2) separated by 2-week ingestion of SUP or control (CON). Outcome measures were assessed pre- and postexercise. When collapsed across groups, a significant decrease in RT performance was seen in the 60-second reaction drill from pre- to postexercise at T1. All other RT tests were similar from pre- to postexercise at T1. Reaction time was not significantly changed by PS. When collapsed across groups, a significant increase in performance of the serial subtraction test was seen. A significant increase (8.9% and 7.1%) in the number of correct answers and a significant decrease (8.0% and 7.5%) in time to answer were seen from pre- to postworkout at T1 and T2, respectively. A significant increase in total MD score from pre- to postworkout was observed for CON but not for PS at T2. Phosphatidylserine significantly attenuated pre- to postexercise perception of fatigue compared to CON. Ingestion of SUP for 14 days appears to attenuate postexercise MD scores and perception of fatigue, but does not affect CF or RT, in recreationally trained individuals. Copyright © 2013 Elsevier Inc.

Intravenous alteplase (rt-PA) increases the risk of hemorrhagic transformation of acute ischemic stroke. The objective of our study was to evaluate clinical, laboratory, and imaging predictors on forecasting the risk of hemorrhagic transformation following treatment with rt-PA. We also evaluated the factors associated with cerebral microbleeds that increase the risk of hemorrhagic transformation. Consecutive patients with acute ischemic stroke admitted between January 1, 2009 and December 31, 2013 were included in the study if they received IV rt-PA, had magnetic resonance imaging (MRI) of the brain on admission, and computed tomography or MRI of the brain at 24 (18-36) hours later to evaluate for the presence of hemorrhagic transformation. The clinical data, lipid levels, platelet count, MRI, and computed tomography images were retrospectively reviewed. The study included 366 patients, with mean age 67 ± 15 years; 46% were women and 88% were white. The median National Institutes of Health Stroke Scale (NIHSS) score was 6 (interquartile range 3-15). Hemorrhagic transformation was observed in 87 (23.8%) patients and cerebral microbleeds were noted in 95 (25.9%). Patients with hemorrhagic transformation tended to be older, nonwhite, have atrial fibrillation, higher baseline NIHSS score, lower cholesterol and triglyceride levels, and cerebral microbleeds and nonlacunar infarcts. Patients with cerebral microbleeds were more likely to be older, have hypertension, hyperlipidemia, previous history of stroke, and prior use of antithrombotics. On multivariate analysis race, NIHSS score, nonlacunar infarct, and presence of cerebral microbleeds were independently associated with hemorrhagic transformation following treatment with rt-PA. Presence of cerebral microbleeds is an independent predictor of hemorrhagic transformation of acute ischemic stroke following treatment with rt-PA. Copyright © 2018 National Stroke Association.

To determine the gestational age (GA)-specific risks for neonatal morbidity and use of interventions in infants born at 30 to 34 completed gestational weeks. A population-based Swedish study including 6674 infants born during 2004-2008. Risks for neonatal morbidity and use of interventions were investigated with respect to GA and birth weight standard deviation scores. Acute lung disorder was diagnosed in 28%, hypoglycemia in 16%, bacterial infection in 15% and hyperbilirubinemia in 59% of the infants. Thirty-eight percent had received antenatal steroid therapy, 43% nasal continuous positive airway pressure, 5.5% required mechanical ventilation, 5.2% were treated with surfactant, and 30% with antibiotic therapy. Neonatal morbidity rates increased with decreasing GA, with odds ratios for different outcomes ranging from 2.1 to 23 at 30 weeks compared with 34 weeks of GA. Low birth weight standard deviation scores was more common at lower GA and was associated with increased morbidity rates. Despite general advances in perinatal care, moderately preterm infants still have substantially increased risks for neonatal morbidity. Whereas the neonatal morbidity rate was similar to results of previous reports, management of respiratory problems differed markedly from other studies. Copyright © 2011 Mosby, Inc.

Patients may experience clinically relevant anxiety at their first radiotherapy (RT) sessions. To date, studies have not investigated during/around the RT simulation the key communication and communication-related predictors of this clinically relevant anxiety. Breast cancer patients (n=227) completed visual analog scale (VAS) assessments of anxiety before and after their first RT sessions. Clinically relevant anxiety was defined as having pre- and post-first RT session VAS scores ⩾4 cm. Communication during RT simulation was assessed with content analysis software (LaComm), and communication-related variables around the RT simulation were assessed with questionnaires. Clinically relevant anxiety at the first RT session was predicted by lower self-efficacy to communicate with the RT team (OR=0.65; p=0.020), the perception of lower support received from the RT team (OR=0.70; p=0.020), lower knowledge of RT-associated side effects (OR=0.95; p=0.057), and higher use of emotion-focused coping (OR=1.09; p=0.013). This study provides RT team members with information about potential communication strategies, which may be used to reduce patient anxiety at the first RT session.

Abstract The study aims to investigate the radiation-induced brain functional alterations in nasopharyngeal carcinoma (NPC) patients who received radiotherapy (RT) using functional magnetic resonance imaging (fMRI) and statistic scale. The fMRI data of 35 NPC patients with RT and 24 demographically matched untreated NPC patients were acquired. Montreal Cognitive Assessment (MoCA) was also measured to evaluate their global cognition performance. Multivariate pattern analysis was performed to find the significantly altered functional connections between these 2 groups, while the linear correlation level was detected between the altered functional connections and the MoCA scores. Forty-five notably altered functional connections were found, which were mainly located between 3 brain networks, the cerebellum, sensorimotor, and cingulo-opercular. With strictly false discovery rate correction, 5 altered functional connections were shown to have significant linear correlations with the MoCA scores, that is, the connections between the vermis and hippocampus, cerebellum lobule VI and dorsolateral prefrontal cortex, precuneus and dorsal frontal cortex, cuneus and middle occipital lobe, and insula and cuneus. Besides, the connectivity between the vermis and hippocampus was also significantly correlated with the attention score, 1 of the 7 subscores of the MoCA. The present study provides new insights into the radiation-induced functional connectivity impairments in NPC patients. The results showed that the RT may induce the cognitive impairments, especially the attention alterations. The 45 altered functional connections, especially the 5 altered functional connections that were significantly correlated to the MoCA scores, may serve as the potential biomarkers of the RT-induced brain functional impairments and provide valuable targets for further functional recovery treatment.

Purpose: The addition of androgen deprivation therapy (ADT) to radiation therapy (RT) is the standard of care for men with intermediate- and high-risk prostate cancer (PC). However, whether competing mortality (CM) affects the ability of ADT to improve, survival remains unanswered. Methods and Materials: We calculated a CM risk score using a Fine-Gray semiparametric model that included age and cardiometabolic comorbidities from a cohort of 17,669 men treated with high-dose RT with or without supplemental ADT for nonmetastatic PC. Fine and Gray competing risk regression analysis was used to assess whether ADT reduced the risk of PC-specific mortality for menmore » with a low versus a high risk of CM among the 4550 patients within the intermediate- and high-risk cohort after adjustment for established PC prognostic factors, year of treatment, site, and ADT propensity score. Results: After a median follow-up of 8.4 years, 1065 men had died, 89 (8.36%) of PC. Among the men with a low CM score, ADT use was associated with a significant reduction in the risk of PC-specific mortality (adjusted hazard ratio 0.35, 95% confidence interval 0.14-0.87, P=.02) but was not for men with high CM (adjusted hazard ratio 1.33, 95% confidence interval 0.77-2.30, P=.30). Conclusions: Adding ADT to high-dose RT appears to be associated with decreased PC-specific mortality risk in men with a low but not a high CM score. These data should serve to heighten awareness about the importance of considering competing risks when determining whether to add ADT to RT for older men with intermediate- or high-risk PC.« less

To develop a scoring system to measure physical morbidity in critical care - the Chelsea Critical Care Physical Assessment Tool (CPAx). The development process was iterative involving content validity indices (CVI), a focus group and an observational study of 33 patients to test construct validity against the Medical Research Council score for muscle strength, peak cough flow, Australian Therapy Outcome Measures score, Glasgow Coma Scale score, Bloomsbury sedation score, Sequential Organ Failure Assessment score, Short Form 36 (SF-36) score, days of mechanical ventilation and inter-rater reliability. Trauma and general critical care patients from two London teaching hospitals. Users of the CPAx felt that it possessed content validity, giving a final CVI of 1.00 (P<0.05). Construct validation data showed moderate to strong significant correlations between the CPAx score and all secondary measures, apart from the mental component of the SF-36 which demonstrated weak correlation with the CPAx score (r=0.024, P=0.720). Reliability testing showed internal consistency of α=0.798 and inter-rater reliability of κ=0.988 (95% confidence interval 0.791 to 1.000) between five raters. This pilot work supports proof of concept of the CPAx as a measure of physical morbidity in the critical care population, and is a cogent argument for further investigation of the scoring system.

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study. PMID:26011220

Men with localized high-risk prostate cancer carry significant risk of prostate cancer-specific mortality. The best treatment approach to minimize this risk is unclear. In this review, we evaluate the role of radiation before and after radical prostatectomy. A critical review of the literature was performed regarding the application of external radiation therapy (RT) in combination with prostatectomy for high-risk localized prostate cancer. Up to 70% of men with high-risk localized disease may require adjuvant therapy because of adverse pathologic features or biochemical recurrence in the absence of systemic disease. The utility of adjuvant RT among men with adverse pathologic features are well established at least regarding minimizing biochemical recurrence risk. The optimal timing of salvage radiation is the subject of ongoing studies. Neoadjuvant RT requires further study but is a potentially attractive method because of decreased radiation field sizes and potential radiobiologic benefits of delivering RT before surgery. Salvage prostatectomy is effective at treating local recurrence after radiation but is associated with significant surgical morbidity. Combining local therapies including radical prostatectomy and RT can be a reasonable approach. Care should be taken at the initial presentation of high-risk localized prostate cancer to consider and plan for the likelihood of multimodality care. Copyright © 2015 Elsevier Inc.

Purpose: To characterize the prevalence, pathophysiology, and natural history of chronic radiation proctitis 5 years following radiation therapy (RT) for localized carcinoma of the prostate. Methods and Materials: Studies were performed in 34 patients (median age 68 years; range 54-79) previously randomly assigned to either 64 Gy in 32 fractions over 6.4 weeks or 55 Gy in 20 fractions over 4 weeks RT schedule using 2- and later 3-dimensional treatment technique for localized prostate carcinoma. Each patient underwent evaluations of (1) gastrointestinal (GI) symptoms (Modified Late Effects in Normal Tissues Subjective, Objective, Management and Analytic scales including effect on activitiesmore » of daily living [ADLs]); (2) anorectal motor and sensory function (manometry and graded balloon distension); and (3) anal sphincteric morphology (endoanal ultrasound) before RT, at 1 month, and annually for 5 years after its completion. Results: Total GI symptom scores increased after RT and remained above baseline levels at 5 years and were associated with reductions in (1) basal anal pressures, (2) responses to squeeze and increased intra-abdominal pressure, (3) rectal compliance and (4) rectal volumes of sensory perception. Anal sphincter morphology was unchanged. At 5 years, 44% and 21% of patients reported urgency of defecation and rectal bleeding, respectively, and 48% impairment of ADLs. GI symptom scores and parameters of anorectal function and anal sphincter morphology did not differ between the 2 RT schedules or treatment techniques. Conclusions: Five years after RT for prostate carcinoma, anorectal symptoms continue to have a significant impact on ADLs of almost 50% of patients. These symptoms are associated with anorectal dysfunction independent of the RT schedules or treatment techniques reported here.« less

Purpose: Cognitive decline is a recognized effect of radiation therapy (RT) in children treated for brain tumors. The importance of the cerebellum and its contribution to cognition have been recognized; however, the effect of RT on cerebellum-linked neurocognitive deficits has yet to be explored. Methods and Materials: Seventy-six children (39 males) at a median 3.3 years of age (range, 1-17 years old) were irradiated for infratentorial ependymoma from 1997 to 2008. The total prescribed dose was 54 to 59.4 Gy administered to the postoperative tumor bed with 5- or 10-mm clinical target volume margin. Age-appropriate cognitive and academic testing was performed prior tomore » the start of RT and was then repeated at 6 months and annually throughout 5 years. The anterior and posterior cerebellum and other normal brain volumes were contoured on postcontrast, T1-weighted postoperative magnetic resonance images registered to treatment planning computed tomography images. Mean doses were calculated and used with time after RT and other clinical covariates to model their effect on neurocognitive test scores. Results: Considering only the statistically significant rates in longitudinal changes for test scores and models that included mean dose, there was a correlation between mean infratentorial dose and intelligence quotient (IQ; −0.190 patients/Gy/year; P=.001), math (−0.164 patients/Gy/year; P=.010), reading (−0.137 patients/Gy/year; P=.011), and spelling scores (−0.147 patients/Gy/year; P=.012), where Gy was measured as the difference between the mean dose received by an individual patient and the mean dose received by the patient group. There was a correlation between mean anterior cerebellum dose and IQ scores (−0.116 patients/Gy/year; P=.042) and mean posterior cerebellum dose and IQ (−0.150 patients/Gy/year; P=.002), math (−0.120 patients/Gy/year; P=.023), reading (−0.111 patients/Gy/year; P=.012), and spelling (−0.117 patients/Gy/year; P=.015) scores. Conclusions: Sparing portions of the cerebellum should be considered in RT planning for children with infratentorial ependymoma because of the potential impact of radiation dose on cognitive function.« less

Scoring systems for outcome prediction in patients with perforated peptic ulcer

PubMed Central

2013-01-01

Background Patients with perforated peptic ulcer (PPU) often present with acute, severe illness that carries a high risk for morbidity and mortality. Mortality ranges from 3-40% and several prognostic scoring systems have been suggested. The aim of this study was to review the available scoring systems for PPU patients, and to assert if there is evidence to prefer one to the other. Material and methods We searched PubMed for the mesh terms “perforated peptic ulcer”, “scoring systems”, “risk factors”, ”outcome prediction”, “mortality”, ”morbidity” and the combinations of these terms. In addition to relevant scores introduced in the past (e.g. Boey score), we included recent studies published between January 2000 and December 2012) that reported on scoring systems for prediction of morbidity and mortality in PPU patients. Results A total of ten different scoring systems used to predict outcome in PPU patients were identified; the Boey score, the Hacettepe score, the Jabalpur score the peptic ulcer perforation (PULP) score, the ASA score, the Charlson comorbidity index, the sepsis score, the Mannheim Peritonitis Index (MPI), the Acute physiology and chronic health evaluation II (APACHE II), the simplified acute physiology score II (SAPS II), the Mortality probability models II (MPM II), the Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity physical sub-score (POSSUM-phys score). Only four of the scores were specifically constructed for PPU patients. In five studies the accuracy of outcome prediction of different scoring systems was evaluated by receiver operating characteristics curve (ROC) analysis, and the corresponding area under the curve (AUC) among studies compared. Considerable variation in performance both between different scores and between different studies was found, with the lowest and highest AUC reported between 0.63 and 0.98, respectively. Conclusion While the Boey score and the ASA score are most commonly used to predict outcome for PPU patients, considerable variations in accuracy for outcome prediction were shown. Other scoring systems are hampered by a lack of validation or by their complexity that precludes routine clinical use. While the PULP score seems promising it needs external validation before widespread use. PMID:23574922

Background Chronic pancreatitis (CP) has a profound independent effect on quality of life (QOL). Our aim was to identify factors that impact the QOL in CP patients. Methods We used data on 1,024 CP patients enrolled in the three NAPS2 studies. Information on demographics, risk factors, co-morbidities, disease phenotype and treatments was obtained from responses to structured questionnaires. Physical (PCS) and mental (MCS) component summary scores generated using responses to the Short Form-12 (SF-12) survey were used to assess QOL at enrollment. Multivariable linear regression models determined independent predictors of QOL. Results Mean PCS and MCS scores were 36.7±11.7 and 42.4±12.2, respectively. Significant (p<0.05) negative impact on PCS scores in multivariable analyses was noted due to constant mild-moderate pain with episodes of severe pain or constant severe pain (10 points), constant mild-moderate pain (5.2), pain-related disability/unemployment (5.1), current smoking (2.9 points) and medical co-morbidities. Significant (p<0.05) negative impact on MCS scores was related to constant pain irrespective of severity (6.8-6.9 points), current smoking (3.9 points) and pain-related disability/unemployment (2.4 points). In women, disability/unemployment resulted in an additional reduction 3.7 point reduction in MCS score. Final multivariable models explained 27% and 18% of the variance in PCS and MCS scores, respectively. Etiology, disease duration, pancreatic morphology, diabetes, exocrine insufficiency and prior endotherapy/pancreatic surgery had no significant independent effect on QOL. Conclusion Constant pain, pain-related disability/unemployment, current smoking, and concurrent co-morbidities significantly affect the QOL in CP. Further research is needed to identify factors impacting QOL not explained by our analyses. PMID:28244497

We evaluated the reliability of eight clinical prediction models for symptomatic intracerebral hemorrhage (sICH) and long-term functional outcome in stroke patients treated with thrombolytics according to clinical practice. In a cohort of 169 patients, 60 patients (35.5%) received IV rtPA according to the European license criteria. The remaining patients received off-label IV rtPA and/or were treated with intra-arterial thrombolysis. We used receiver operator characteristic curves to analyze the discriminative capacity of the MSS score, the HAT score, the SITS SICH score, the SEDAN score and the GRASPS score for sICH according to the NINDS and the ECASSII criteria. Similarly, the discriminative capacity of the s-TPI, the iScore and the DRAGON score were assessed for the modified Rankin Scale (mRS) score at 3 months poststroke. An area under the curve (c-statistic) >0.8 was considered to reflect good discriminative capacity. The reliability of the best performing prediction model was further examined with calibration curves. Separate analyses were performed for patients meeting the European license criteria for IV rtPA and patients outside these criteria. For prediction of sICH c-statistics were 0.66-0.86 and the MMS yielded the best results. For functional outcome c-statistics ranged from 0.72 to 0.86 with s-TPI as best performer. The s-TPI had the lowest absolute error on the calibration curve for predicting excellent outcome (mRS 0-1) and catastrophic outcome (mRS 5-6). All eight clinical models for outcome prediction after thrombolysis for acute ischemic stroke showed fair predictive value in patients treated according daily practice. The s-TPI had the best discriminatory ability and was well calibrated in our study population. Copyright © 2014 Elsevier B.V. All rights reserved.

Carlson, Julie A., E-mail: Julie.A2.Carlson@ucdenver.edu; Rusthoven, Chad; DeWitt, Peter E.

Purpose: We performed a patterns-of-care analysis evaluating the effects of newer technology and recent research findings on treatment decisions over 26 years to determine whether patients with cervical cancer are being appropriately selected for treatment to optimize the therapeutic ratio. Methods and Materials: A retrospective analysis was conducted using the Surveillance, Epidemiology and End Results (SEER) program from 1983 to 2009. We identified 10,933 women with stage IB-IIB cervical carcinoma. Results: Of the 10,933 subjects identified, 40.1% received surgery, 26.8% received radiation (RT), and 33.1% received surgery plus RT. RT use increased after 2000 compared to prior to 2000, with amore » corresponding decrease in surgery and surgery plus RT. Among patients with risk factors including tumor size >4 cm, positive parametria, and positive lymph nodes, declining use of surgery plus RT was observed. However, 23% of patients with tumors >4 cm, 20% of patients with positive parametria, and 55% of node-positive patients continued to receive surgery plus RT as of 2009. Factors associated with increased use of surgery plus RT included patient age <50 and node-positive status. Conclusions: In this largest patterns-of-care analysis to date for patients with locally advanced cervical cancer, we found a substantial proportion of patients continue to undergo surgery followed by radiation, despite randomized data supporting the use of definitive radiation therapy, with lower morbidity than surgery and radiation.« less

Hemorrhagic transformation (HT) is a devastating complication for patients with acute ischemic stroke who are treated with tissue plasminogen activator (tPA). It is associated with high morbidity and mortality, but no effective treatments are currently available to reduce HT risk. Therefore, methods to prevent HT are urgently needed. In this study, we used TWS119, an inhibitor of glycogen synthase kinase 3β (GSK-3β), to evaluate the role of the Wnt/β-catenin signaling pathway in recombinant tPA (rtPA)-induced HT. Sprague-Dawley rats were subjected to a middle cerebral artery occlusion (MCAO) model of ischemic stroke and then were administered rtPA, rtPA combined with TWS119, or vehicle at 4 h. The animals were sacrificed 24 h after infarct induction. Rats treated with rtPA showed evident HT, had more severe neurologic deficit, brain edema, and blood-brain barrier breakdown, and had larger infarction volume than did the vehicle group. Rats treated with TWS119 had significantly improved outcomes compared with those of rats treated with rtPA alone. In addition, Western blot analysis showed that TWS119 increased the protein expression of β-catenin, claudin-3, and ZO-1 while suppressing the expression of GSK-3β. These results suggest that TWS119 reduces rtPA-induced HT and attenuates blood-brain barrier disruption, possibly through activation of the Wnt/β-catenin signaling pathway. This study provides a potential therapeutic strategy to prevent tPA-induced HT after acute ischemic stroke.

Integrated skin flash planning technique for intensity-modulated radiation therapy for vulvar cancer prevents marginal misses and improves superficial dose coverage.

Radiation therapy (RT) plays a definitive role in locally advanced vulvar cancer, and in the adjuvant setting with high risk postoperative features after wide local excision. There is significant morbidity associated with traditional, large RT fields using 2D or 3D techniques, and the use of intensity-modulated radiation therapy (IMRT) in vulvar cancer is increasing. However, there remains a paucity of technical information regarding the prevention of a marginal miss during the treatment planning process. The use of an integrated skin flash (ISF) during RT planning can be used to account for anatomic variation, and intra- and interfraction motion seen during treatment. Herein we present the case of a patient with a T1aN0M0, Stage IA vulva cancer to illustrate the progressive vulvar swelling and lymph edema seen during treatment and retrospectively evaluate the dosimetric effects of using an ISF RT plan vs standard RT planning techniques. Standard planning techniques to treat vulvar cancer patients with IMRT do not sufficiently account for the change in patient anatomy and can lead to a marginal miss. ISF is an RT planning technique that can decrease the risk of a marginal miss and the technique is easily implemented during the planning stages of RT treatment. Furthermore, use of an ISF technique can improve vulvar clinical target volume coverage and plan homogeneity. Based on our experience, and this study, a 2-cm ISF is suggested to account for variations in daily clinical setup and changes in patient anatomy during treatment. Published by Elsevier Inc.

To investigate the risk of postradiotherapy prostate-specific antigen (PSA) failure on the basis of pretreatment risk factors in prostate cancer patients with and without perineural invasion (PNI) in prostate biopsy specimens and to explain the observation that otherwise low-risk patients with PNI experience decreased freedom from PSA failure after external beam radiotherapy (RT). The study cohort consisted of 381 patients who underwent RT between 1989 and 2000 for clinically localized prostate cancer. A single genitourinary pathologist scored the absence or presence of PNI on all prostate biopsy specimens. Patients were divided into low-, intermediate- and high-risk subgroups on the basis of their 1992 American Joint Committee on Cancer T-stage, pretreatment PSA level, and Gleason score. Cox regression uni- and multivariate analyses were performed to evaluate whether the presence or absence of PNI in the biopsy specimen was a predictor of the time to post-RT PSA failure for patients in each pretreatment risk group. PSA failure was defined using the American Society for Therapeutic Radiology and Oncology consensus definition. Actuarial PSA failure-free survival was estimated using the Kaplan-Meier method, and comparisons were performed using the log-rank test. Cox regression univariate analysis revealed that PNI was a significant predictor of the time to PSA failure in the low-risk (p = 0.04) and high-risk (p = 0.03) cohorts. The 5-year PSA failure-free survival rate was 50% vs. 80% (p = 0.04) in low-risk patients, 70% vs. 75% (p = 0.72) in intermediate-risk patients, and 29% vs. 53% (p = 0.03) in high-risk patients with and without PNI, respectively. Cox regression multivariate analysis within the high-risk group revealed that a PSA level > or =20 ng/mL (p = 0.01) and Gleason score > or =8 (p = 0.02), but not PNI, were the only significant predictors of the time to PSA failure after RT. However, an association was found between the presence of PNI in the needle biopsy specimen and a biopsy Gleason score of 8-10 (p = 0.06). The association was stronger between the presence of PNI in the needle biopsy specimen and a biopsy Gleason score of 7-10 (p = 0. 033). A decrement in PSA outcome after RT for low-risk patients with PNI-positive biopsy specimens was found. The association between PNI and high Gleason score provides a possible explanation for the loss of statistical significance of PNI in the Cox regression multivariate analysis of the high-risk cohort. The data suggest that PNI found in the biopsy specimen of an otherwise low-risk patient predicts for occult high-grade disease that is missed owing to the sampling error associated with prostate biopsy. The association between PNI and a high Gleason score argues for the use of more aggressive therapy, such as hormonal therapy with RT and/or dose escalation, in these select patients.

Purpose: Comparison of health-related quality of life after whole pelvic (WPRT) and prostate-only (PORT) external beam radiotherapy for prostate cancer. Methods and Materials: A group of 120 patients (60 in each group) was surveyed prospectively before radiation therapy (RT) (time A), at the last day of RT (time B), at a median time of 2 months (time C) and >1 year after RT (time D) using a validated questionnaire (Expanded Prostate Cancer Index Composite). All patients were treated with 1.8- to 2.0-Gy fractions up to 70.2 to 72.0 Gy with or without WPRT up to 45 to 46 Gy. Pairsmore » were matched according to the following criteria: age {+-} 5years, planning target volume {+-} 10 cc (considering planning target volume without pelvic nodes for WPRT patients), urinary/bowel/sexual function score before RT {+-} 10, and use of antiandrogens. Results: With the exception of prognostic risk factors, both groups were well balanced with respect to baseline characteristics. No significant differences were found with regard to urinary and sexual score changes. Mean bladder function scores reached baseline levels in both patient subgroups after RT. However, bowel function scores decreased significantly more for patients after WPRT than in those receiving PORT at all times (p < 0.01, respectively). Significant differences were found for most items in the bowel domain in the acute phase. At time D, patients after WPRT reported rectal urgency (>once a day in 15% vs. 3%; p = 0.03), bloody stools ({>=}half the time in 7% vs. 0%; p = 0.04) and frequent bowel movements (>two on a typical day in 32% vs. 7%; p < 0.01) more often than did patients after PORT. Conclusion: In comparison to PORT, WPRT (larger bladder and rectum volumes in medium dose levels, but similar volumes in high dose levels) was associated with decreased bowel quality of life in the acute and chronic phases after treatment but remained without adverse long-term urinary effects.« less

Purpose: Radioimmunoscintigraphy (RIS) has the potential to demonstrate early recurrences after prostatectomy and might be useful in selecting patients for salvage radiotherapy (RT). Methods: A total of 82 patients with adenocarcinoma of the prostate were treated with salvage RT between 1988 and 2005, for an elevated prostate-specific antigen (PSA) level after prostatectomy. Of the 82 patients, 32% had Gleason score 6 or less disease, 54% Gleason score 7 disease, 70% had Stage pT3 disease, 55% had positive margins, and 5% had pathologic lymph node involvement. The median pre-RT PSA level was 0.63 ng/mL. Of the 82 patients, 47 (57%) hadmore » a pre-RT RIS (ProstaScint) scan, which was used for both patient selection and target delineation. The RT regimen was a median dose of 66 Gy to the prostate bed. Also, 64% received androgen deprivation therapy. Biochemical failure was defined as a PSA level >0.1 ng/mL and increasing. Results: Patients with a pre-RT RIS scan had a lower preoperative PSA level (p = 0.0240) and shorter follow-up (p = 0.0221) than those without RIS. With a median follow-up of 44 months, the biochemical control rate was 56% at 3 years and 48% at 5 years. Margin status was the only factor associated with biochemical control on univariate (p = 0.0055) and multivariate (p = 0.0044) analysis. Patients who had prostate bed-only uptake on RIS (n = 38) did not have improved outcomes, with biochemical control rates of 51% at 3 years and 40% at 5 years. Conclusion: Patients treated with salvage RT had modest responses. Patients who were selected for treatment with RIS did not have better biochemical outcomes. Our results indicated that patients with positive margins were most likely to benefit from salvage RT.« less

Interprofessional education (IPE) involves two or more professions engaged in learning with, from and about each other. An initiative was undertaken to explore IPE for radiation therapy (RT) and medical physics (MP) students through a newly developed workshop based around simulated learning. The aims of this study were to explore RT and MP students' perceptions of working as part of a collaborative team and of their own and the other group's professional roles. Student perceptions of the simulation education tool, the virtual environment for radiotherapy training (VERT) system, were also investigated. RT and MP students were invited to participate in a 4-hour interprofessional workshop. Pre- and post-workshop surveys were employed to collect demographic data, students' perceptions of interdisciplinary education (interdisciplinary education perception scale (IEPS)) and workshop evaluation (bespoke questionnaire). Fifteen students attended the workshop (RT, n = 8; MP, n = 7). Thirteen pre- and post-questionnaires were returned (Pre-questionnaire: RT, n = 6, response rate, 75%; MP, n = 7, response rate, 100%; post-questionnaire: RT, n = 7, response rate, 87.5%; MP, n = 6, response rate 85.7%). For both student groups combined, IEPS scores ranged from 64 to 108 and 71 to 108 in the pre- and post-questionnaires, respectively, with insignificant differences in the mean scores post-intervention (Z = -1.305, P = 0.192). Satisfaction with VERT as a simulation tool was high for both student groups. The interprofessional student workshop served to promote interprofessional collaboration for RT and MP students. VERT was reported as an appropriate education tool for this purpose, enabling access to virtual clinical equipment common to both student groups. It is suggested that IPE continues to be offered and investigated in RT and MP students, in order to improve effective interprofessional strategies which may enrich future professional collaboration. © 2018 The Authors.

To compare open radical prostatectomy (RP) and robot-assisted laparoscopic prostatectomy (RALP), and to determine whether RALP is associated with a higher risk of features that determine recommendations for postoperative radiation therapy (RT). Patients undergoing RP from 2003 to 2007 were stratified into two groups: open RP and RALP. Preoperative (PSA level, T stage and Gleason score), pathological factors (T stage, Gleason score, extracapsular extension [ECE] and the status of surgical margins and seminal vesicle invasion [SVI]) and early treatment with RT or referral for RT within 6 months were compared between the groups. Multivariate analysis was used to control for selection bias in the RALP group. In all, 904 patients were identified; 368 underwent RALP and 536 underwent open RP (retropubic or perineal). Patients undergoing open RP had a higher pathological stage with ECE present in 24.8% vs 19.3% in RALP (P = 0.05) and SVI in 10.3% vs 3.8% (P < 0.001). In the RALP vs open RP group, there were positive surgical margins in 31.5% vs 31.9% (P = 0.9) and there were postoperative PSA levels of (3) 0.2 ng/mL in 5.7% vs 6.3% (P = 0.7), respectively. On multivariate analysis to control for selection bias, RALP was not associated with indication for RT (odds ratio (OR) 1.10, P = 0.55), or referral for RT (OR 1.04, P = 0.86). RALP was not associated with an increase in either indication or referral for early postoperative RT.

The Van Nuys Prognostic Index (VNPI) is a simple score for predicting the risk of local recurrence (LR) in patients with Ductal Carcinoma In Situ (DCIS) conservatively treated. This score combines three independent predictors of Local Recurrence. The VNPI has recently been updated with the addition of age as a fourth parameter into the scoring system (University of Southern California/ VNPI). Our database consisted of 408 women with DCIS. Applying the USC/VNPI we reviewed retrospectively 259 patients who were treated with breast conserving surgery with or without radiotherapy (RT). Of these patients 63.5% had a low VNPI score, 32% intermediate and 4.5% a high score. In the low score group, the majority of the patients underwent Conservative Surgery (CS) without RT while in the intermediate group, almost half of the patients received RT. Eighty-three percent (83%) of the patients with high VNPI were treated with Conservative Surgery plus RT. Nodal assessment by Sentinel Lymph Node Biopsy was obtained in 32 patients since 2002. Twenty-one Local Recurrences were observed (8%) with a mean follow up of 130 months: sixteen were invasive. No statistically significant differences in Disease Free Survival were reached in all groups of VNPI score between patients treated with Conservative Surgery or Conservative Surgery plus RT. However it was noted that the higher the VNPI score, the lower was the risk of local recurrence in the group treated additionally with RT, even though it was not statistically significant. Further analysis included those patients treated with Conservative Surgery alone and followed up. Disease-free survival (DFS) at 10 years was 94% with low VNPI and 83% in both intermediate and high score (P < 0.05). No significant differences were observed in the subgroups of VNPI. The Local Relapse rate after Conservative Surgery alone, increased with tumor size, margin width, and pathology classification (P < 0,05), while age was not found to be a significant factor. Lesions with only mammographic appearances are associated with lower DFS but it did not reach significance (P = ns), while assumption of estrogenic hormones and familial history of breast cancer are significant factors associated with a higher risk of local recurrence. After multivariate analysis including seven clinical and pathological factors, the only significant predictors of local recurrence remained margin width of surgical excision, previous therapy with estrogens (contraceptives or Hormone Replacement Therapy) and the Van Nuys pathologic classification. The overall survival breast cancer specific was 99% and no differences were observed between groups (P = ns). The comparison of patients treated with a total mastectomy and those conservatively treated showed a significantly better local relapse free survival rate obtained with mastectomy (98.2% vs. 89.7% at 10 years P = 0.02). However, the overall cause-specific survival did not prove any better outcome (98.7% in both groups). Of the 32 patients who underwent a Sentinel Lymph Node Biopsy, four were found to have micrometastases and all of them had a previous Directional Vacuum Assisted Biopsy. Although in our series there is not a significant difference in LR rates by the parameter of age, the new USC/VNPI is still a simple and reliable scoring system for therapeutic management of DCIS. We did not find any statistically significant advantage in groups treated with the addition of RT. Obtaining wide surgical margins appears to be the strongest prognostic factor for local recurrence, regardless of other pathological factors or the addition of adjuvant radiation therapy. However, only prospective randomized studies can precisely predict the risk of LR of conservatively treated DCIS. The clinical significance of Sentinel Lymph Nodes micrometastases Immuno-Histo-Chemistry-detected found in DCIS patients remains uncertain. However, we hypothesize that the anatomical disruption after preoperative biopsy procedures increases the likelihood of epithelial cell displacement and the frequency of IHC-positive Sentinel Lymph Nodes, both of which are directly proportional to the degree of manipulation.

Background and Purpose— Several studies have reported unexplained worse outcomes after stroke in women but none included the full spectrum of symptomatic ischemic cerebrovascular events while adjusting for prior handicap. Methods— Using a prospective population-based incident cohort of all transient ischemic attack/stroke (OXVASC [Oxford Vascular Study]) recruited between April 2002 and March 2014, we compared pre-morbid and post-event modified Rankin Scale score (mRS) in women and men and change in mRS score 1 month, 6 months, 1 year, and 5 years after stroke. Baseline stroke-related neurological impairment was measured with the National Institutes of Health Stroke Scale. Results— Among 2553 patients (50.6% women) with a first transient ischemic attack/ischemic stroke, women had a worse handicap 1 month after ischemic stroke (age-adjusted odds ratio for mRS score, 1.35; 95% confidence interval, 1.12–1.63). However, women also had a higher pre-morbid mRS score compared with men (age-adjusted odds ratio, 1.58; 95% confidence interval, 1.36–1.84). There was no difference in stroke severity when adjusting for age and pre-morbid mRS (odds ratio, 1.10; 95% confidence interval, 0.90–1.35) and no difference in the pre-/poststroke change in mRS at 1 month (age-adjusted odds ratio, 1.00; 95% confidence interval, 0.82–1.21), 6 months, 1 year, and 5 years. Women had a lower mortality rate, and there was no sex difference in risk of recurrent stroke. Conclusions— We found no evidence of a worse outcome of stroke in women when adjusting for age and pre-morbid mRS. Failure to account for sex differences in pre-morbid handicap could explain contradictory findings in previous studies. Properties of the mRS may also contribute to these inconsistencies.

American Heart Association cardiovascular health metrics are intimately related to cardiovascular diseases. Acting as a key independent risk factor for high morbidity and mortality of cardiovascular diseases, hypertension and its relationship between health status get urgent attention. While the influence of individual health status changes and the future risk of new-onset hypertension is rarely understood, the present study applied this construct to assess the changes of cardiovascular health status and the morbidity of hypertension in Kailuan cohort study in north China. The Cardiovascular Health Score (CHS) was evaluated by the follow-ups of 2006–2007, 2008–2009, 2010–2011 and 2012–2013. The study population (n = 19381) was divided into 5 groups based on the changes in their CHS score between the first two follow-ups (△CHS) of 2006–2007 and 2008–2009 (≤-2, -1, 0, 1, ≥2). The morbidity of hypertension was collected during 2010–2011 and 2012–2013 follow-ups. Data analysis showed that during a median follow-up of 3.79±0.96 years, morbidity of hypertension had a graded relationship with △CHS. As △CHS scored from low to high, the standardized morbidity of hypertension for all participants were 81.40, 75.47, 68.37, 71.43 and 83.13 per 1000 person-year, respectively. An increased △CHS score of 1 was associated with a 10% decrease in the future risk of new-onset hypertension(HR: 0.90, 95% CI: 0.88–0.92). In conclusion, there was a strong inverse relationship between the incidence of new-onset hypertension and elevation of cardiovascular health metrics. Population-wide prevention, especially the promotion of lifestyle improvements, is critical to reducing the morbidity of new-onset hypertension. PMID:27434049

ASCENDE-RT: An Analysis of Treatment-Related Morbidity for a Randomized Trial Comparing a Low-Dose-Rate Brachytherapy Boost with a Dose-Escalated External Beam Boost for High- and Intermediate-Risk Prostate Cancer

Purpose: To report the genitourinary (GU) and gastrointestinal (GI) morbidity and erectile dysfunction in a randomized trial comparing 2 methods of dose escalation for high- and intermediate-risk prostate cancer. Methods and Materials: ASCENDE-RT (Androgen Suppression Combined with Elective Nodal and Dose Escalated Radiation Therapy) enrolled 398 men, median age 68 years, who were then randomized to either a standard arm that included 12 months of androgen deprivation therapy and pelvic irradiation to 46 Gy followed by a dose-escalated external beam radiation therapy (DE-EBRT) boost to 78 Gy, or an experimental arm that substituted a low-dose-rate prostate brachytherapy (LDR-PB) boost. At clinic visits, investigators recorded GUmore » and GI morbidity and information on urinary continence, catheter use, and erectile function. Exclusion of 15 who received nonprotocol treatment and correction of 14 crossover events left 195 men who actually received a DE-EBRT boost and 188, an LDR-PB boost. Median follow-up was 6.5 years. Results: The LDR-PB boost increased the risk of needing temporary catheterization and/or requiring incontinence pads. At 5 years the cumulative incidence of grade 3 GU events was 18.4% for LDR-PB, versus 5.2% for DE-EBRT (P<.001). Compared with the cumulative incidence, the 5-year prevalence of grade 3 GU morbidity was substantially lower for both arms (8.6% vs 2.2%, P=.058). The 5-year cumulative incidence of grade 3 GI events was 8.1% for LDR-PB, versus 3.2% for DE-EBRT (P=.124). The 5-year prevalence of grade 3 GI toxicity was lower than the cumulative incidence for both arms (1.0% vs 2.2%, respectively). Among men reporting adequate baseline erections, 45% of LDR-PB patients reported similar erectile function at 5 years, versus 37% after DE-EBRT (P=.30). Conclusions: The incidence of acute and late GU morbidity was higher after LDR-PB boost, and there was a nonsignificant trend for worse GI morbidity. No differences in the frequency of erectile dysfunction were observed.« less

Local progression, in patients with hormone-refractory prostate cancer, often causes significant morbidity. Pelvic radiotherapy (RT) provides effective palliation in this setting, with most published studies supporting the use of high-dose regimens. The aim of the present study was to examine the role of split-course hypofractionated RT used at our institution in treating this group of patients. A total of 34 men with locoregionally progressive hormone-refractory prostate cancer, treated with a split course of pelvic RT (45-60 Gy in 18-24 fractions) between 2000 and 2008 were analyzed. The primary endpoints were the response rate and actuarial locoregional progression-free survival. Secondary endpoints included overall survival, compliance, and acute and late toxicity. The median age was 71 years (range, 53-88). Treatment resulted in an overall initial response rate of 91%, a median locoregional progression-free survival of 43 months, and median overall survival of 28 months. Compliance was excellent and no significant late toxicity was reported. The split course pelvic RT described has an acceptable toxicity profile, is effective, and compares well with other high-dose palliative regimens that have been previously reported.

Card, Tim R.; West, Joe

2016-01-01

Background We have assessed whether the linkage between routine primary and secondary care records provided an opportunity to develop an improved population based co-morbidity score with the combined information on co-morbidities from both health care settings. Methods We extracted all people older than 20 years at the start of 2005 within the linkage between the Hospital Episodes Statistics, Clinical Practice Research Datalink, and Office for National Statistics death register in England. A random 50% sample was used to identify relevant diagnostic codes using a Bayesian hierarchy to share information between similar Read and ICD 10 code groupings. Internal validation of the score was performed in the remaining 50% and discrimination was assessed using Harrell’s C statistic. Comparisons were made over time, age, and consultation rate with the Charlson and Elixhauser indexes. Results 657,264 people were followed up from the 1st January 2005. 98 groupings of codes were derived from the Bayesian hierarchy, and 37 had an adjusted weighting of greater than zero in the Cox proportional hazards model. 11 of these groupings had a different weighting dependent on whether they were coded from hospital or primary care. The C statistic reduced from 0.88 (95% confidence interval 0.88–0.88) in the first year of follow up, to 0.85 (0.85–0.85) including all 5 years. When we stratified the linked score by consultation rate the association with mortality remained consistent, but there was a significant interaction with age, with improved discrimination and fit in those under 50 years old (C = 0.85, 0.83–0.87) compared to the Charlson (C = 0.79, 0.77–0.82) or Elixhauser index (C = 0.81, 0.79–0.83). Conclusions The use of linked population based primary and secondary care data developed a co-morbidity score that had improved discrimination, particularly in younger age groups, and had a greater effect when adjusting for co-morbidity than existing scores.

Clinically lymph node-positive (cN+) prostate cancer (PCa) is an often-fatal disease. Its optimal management remains largely undefined given a lack of prospective, randomized data to inform practice. We sought to describe modern practice patterns in the management of cN+PCa and assess the effect of adding radiation therapy (RT) to androgen deprivation therapy (ADT) on survival using the National Cancer Data Base. Patients with cN+PCa and without distant metastases diagnosed between 2004 and 2011 were included. Five-year overall survival for patients diagnosed between 2004 and 2006 and treated with ADT alone or ADT+RT were compared. Propensity score (PS) matching was used to balance baseline characteristics, and Cox multivariate regression analysis was used to estimate hazard ratios (HRs) for all-cause mortality. Of 3,540 total patients, 32.2% were treated with ADT alone and 51.4% received ADT+RT. Compared with ADT alone, patients treated with ADT+RT were younger and more likely to have private insurance, lower comorbidity scores, higher Gleason scores, and lower PSA values. After PS matching, 318 patients remained in each group. Compared with ADT alone, ADT+RT was associated with a 50% decreased risk of five-year all-cause mortality (HR = 0.50, 95% CI: 0.37-0.67, two-sided P<0.001; crude OS rate: 71.5% vs. 53.2%). Using a large national database, we have identified a statistically significant survival benefit for patients with cN+PCa treated with ADT+RT. These data, if appropriately validated by randomized trials, suggest that a substantial proportion of such patients at high risk for prostate cancer death may be undertreated, warranting a reevaluation of current practice guidelines.

Purpose: To investigate the efficacy of palliative radiotherapy (RT) in relieving metastatic bone pain in elderly patients. Methods and Materials: The response to RT for palliation of metastatic bone pain was evaluated from a prospective database of 558 patients between 1999 and 2008. The pain scores and analgesic intake were used to calculate the response according to the International Bone Metastases Consensus Working Party palliative RT endpoints. Subgroup analyses for age and other demographic information were performed. Results: No significant difference was found in the response rate in patients aged >=65, >=70, and >=75 years compared with younger patients atmore » 1, 2, or 3 months after RT. The response was found to be significantly related to the performance status. Conclusion: Age alone did not affect the response to palliative RT for bone metastases. Elderly patients should be referred for palliative RT for their painful bone metastases, regardless of age, because they receive equal benefit from the treatment.« less

Radiation-induced cognitive decline is relatively common after treatment for primary and metastatic brain tumors; however, identifying dosimetric parameters that are predictive of radiation-induced cognitive decline is difficult due to the heterogeneity of patient characteristics. The memory function is especially susceptible to radiation effects after treatment. The objective of this study is to correlate volumetric radiation doses received by critical neuroanatomic structures to post-radiation therapy (RT) memory impairment. Between 2008 and 2011, 53 patients with primary brain malignancies were treated with conventionally fractionated RT in prospectively accrued clinical trials performed at our institution. Dose-volume histogram analysis was performed for the hippocampus, parahippocampus, amygdala, and fusiform gyrus. Hopkins Verbal Learning Test-Revised scores were obtained at least 6 months after RT. Impairment was defined as an immediate recall score ≤15. For each anatomic region, serial regression was performed to correlate volume receiving a given dose (V D(Gy) ) with memory impairment. Hippocampal V 53.4Gy to V 60.9Gy significantly predicted post-RT memory impairment ( P  < .05). Within this range, the hippocampal V 55Gy was the most significant predictor ( P  = .004). Hippocampal V 55Gy of 0%, 25%, and 50% was associated with tumor-induced impairment rates of 14.9% (95% confidence interval [CI], 7.2%-28.7%), 45.9% (95% CI, 24.7%-68.6%), and 80.6% (95% CI, 39.2%-96.4%), respectively. The hippocampal V 55Gy is a significant predictor for impairment, and a limiting dose below 55 Gy may minimize radiation-induced cognitive impairment.

The purpose of this study was to evaluate acute and late radiation morbidity in patients with gynaecologic malignancy using the RTOG criteria and Franco-Italian glossary, and to compare the usefulness and disadvantages of each system. Between February 2001 and February 2003, 107 patients with gynaecologic malignancy who received either radical or djuvant external radiotherapy +/- intracavitary brachytherapy or radiochemotherapy were enrolled in this study. The patients were evaluated before radiotherapy and weekly during radiotherapy for acute morbidity using the RTOG grading system and Franco-Italian glossary. Postradiotherapy evaluation was done one month after radiotherapy and at 3-month intervals thereafter. Median follow-up duration was 17 months. Morbidity was graded and recorded according to each scoring system. Median age was 46 years (range 37-82). Sixty-four patients (59.8%) had endometrial cancer. Radical radiotherapy was applied to 26 patients because of inoperability and 81 patients received postoperative radiotherapy. Biologically effective doses for the bladder, rectum and vagina were 98.39, 103.54 and 121.81, respectively, for late morbidity (BED3); 70.88, 72.84 and 80.92, respectively, for acute morbidity (BED10). According to the RTOG grading system acute morbidity rate for the genitourinary and gastrointestinal systems, and skin were 52.3%, 83.2% and 63.5%, respectively. Late morbidity rate for the bladder, colon-rectum, skin and vagina were 16.8%, 20.6%, 47.7% and 51.4%, respectively. The morbidity rate for the bladder, nonspecific abdominal, hematopoietic system, uterus-vulva-vagina, skin and rectum were 35.4%, 29.9%, 5.6%, 60.8%, 40.1% and 32.7%, respectively using the Franco-Italian glossary. In patients with carcinoma of the vulva--whose treatment fields were wider--acute morbidity rate according to RTOG criteria was higher (p = 0.057); photon energy (6 Mv rather than 1.25 MV) (p = 0.01) and treatment interruption of more than eight days (p = 0.019) were correlated with decreased long-term morbidity. According to the Franco-Italian glossary morbidity rates were higher in patients who received chemotherapy (p = 0.047), both external radiotherapy and brachytherapy (p = 0.022) and treatment interruption of less than eight days (p = 0.019). There is no common language between the RTOG grading system and Franco-Italian glossary for defining and scoring radiation morbidity. Up to date no standard and well-defined system has been developed for recording and reporting acute and late radiation morbidity in gynaecologic malignancy, but rather it depends on the subjective evaluation and experience of a radiation oncologist and subjective complaints of the patient, and sometimes on clinical findings. A standard and well-defined user friendly objective scoring system is needed to define and predict the morbidity rate more properly.

In February 2012, an outbreak of peste des petits ruminants (PPR) was suspected in Ghardaïa district at the center of Algeria. Clinical, serological, and molecular investigations were performed to confirm the occurrence of PPRV. The overall morbidity, mortality, and case fatality rates of the ten flocks investigated were 12.2, 2.5, and 20.3 %, respectively. At the flock level, positivity to PPR was 100, 90, and 100 % by competitive ELISA (c-ELISA), RT-PCR of blood samples, and oculo-nasal swabs, respectively. At the individual levels, the present study showed that out of 186 samples collected from the same animals 17/62 (27.41 %), 14/62 (22.85 %), and 36/62 (58.06 %) were positive by c-ELISA, RT-PCR of blood samples, and RT PCR of oculo-nasal swabs, respectively. The positivity of PPR was significantly higher using RT-PCR of oculo-nasal swabs than c-ELISA and RT-PCR of blood samples. The N gene partial sequence of five PPRV-positive amplicons revealed 100 % homology among them and phylogenetically belonged to lineage IV. The sequences also showed similarity range of 97-99 % with the strains implicated in the Moroccan and Tunisian outbreaks, however, suggesting that a similar strain is circulating across this area of the Maghreb and highlighting the need for a regional control approach.

The objective of this study was to describe the sociodemographic characteristics and the quality of life of the caregivers of elderly individuals with a stroke history, and correlate morbidity with the caregivers' quality of life scores. This is a cross-sectional household survey that interviewed the caregivers of elderly individuals using the following tools: a semi-structured instrument; the World Health Organization Quality of life-BREF; and the Brazilian Multidimensional Functional Assessment Questionnaire. Descriptive analysis and Pearson's correlation (p<0.05) were performed. Most participants were female (93.5%), with a mean age of 55.4±14.17 years, married or living with a partner (58.7%), with four to eight years of education (28.3%), and an income equivalent to one minimum wage salary (34.8%). The highest quality of life score was in the social relations domain (67.57) and the lowest was in the environmental domain (54.82). The highest number of caregiver morbidities correlated with the lowest scores in all quality of life domains.

Reirradiation (reRT) is a valid option with considerable efficacy in patients with recurrent high-grade glioma, but it is still not known which patients might be optimal candidates for a second course of irradiation. This study validated a newly developed prognostic score independently in an external patient cohort. The reRT risk score (RRRS) is based on a linear combination of initial histology, clinical performance status, and age derived from a multivariable model of 353 patients. This score can predict post-recurrence survival (PRS) after reRT. The validation dataset consisted of 212 patients. The RRRS differentiates three prognostic groups. Discrimination and calibration were maintained in the validation group. Median PRS times in the development cohort for the good/intermediate/poor risk categories were 14.2, 9.1, and 5.3 months, respectively. The respective groups within the validation cohort displayed median PRS times of 13.8, 8.8, and 3.8 months, respectively. Uno's C for development data was 0.64 (CI: 0.60-0.69) and for validation data 0.63 (CI: 0.58-0.68). The RRRS has been successfully validated in an independent patient cohort. This linear combination of three easily determined clinicopathological factors allows for a reliable classification of patients and may be used as stratification factor for future trials.

To characterize the surface topography of several dental implants for commercial use. Dental implants analyzed were Certain (Biomet 3i), Tissue Level (Straumann), Interna (BTI), MG-InHex (MozoGrau), SPI (Alphabio) and Hikelt (Bioner). Surface topography was ascertained using a confocal microscope with white light. Roughness parameters obtained were: Ra, Rq, Rv, Rp, Rt, Rsk and Rku. The results were analysed using single-factor ANOVA and Student-Neuman-Keuls (p<0.05) tests. Certain and Hikelt obtained the highest Ra and Rq scores, followed by Tissue Level. Interna and SPI obtained lower scores, and MG-InHex obtained the lowest score. Rv scores followed the same trend. Certain obtained the highest Rp score, followed by SPI and Hikelt, then Interna and Tissue Level. MG-InHex obtained the lowest scores. Certain obtained the highest Rt score, followed by Interna and Hikelt, then SPI and Tissue Level. The lowest scores were for MG-InHex. Rsk was negative (punctured surface) in the MG-InHex, SPI and Tissue Level systems, and positive (pointed surface) in the other systems. Rku was higher than 3 (Leptokurtic) in Tissue Level, Interna, MG-InHex and SPI, and lower than 3 (Platykurtic) in Certain and Hikelt. The type of implant determines surface topography, and there are differences in the roughness parameters of the various makes of implants for clinical use.

To retrospectively evaluate the diagnostic performance of free-breathing diffusion-weighted imaging (FB-DWI) with modified imaging parameter settings for detecting hepatocellular carcinomas (HCCs). Fifty-one patients at risk for HCC were scanned with both FB-DWI and respiratory-triggered DWI with the navigator echo respiratory-triggering technique (RT-DWI). Qualitatively, the sharpness of the liver contour, the image noise and the chemical shift artifacts on each DWI with b -values of 1000 s/mm 2 were independently evaluated by three radiologists using 4-point scoring. We compared the image quality scores of each observer between the two DWI methods, using the Wilcoxon signed-rank test. Quantitatively, we compared the signal-to-noise ratios (SNRs) of the liver parenchyma and lesion-to-nonlesion contrast-to-noise ratios (CNRs) after measuring the signal intensity on each DWI with a b-factor of 1000 s/mm 2 . The average SNRs and CNRs between the two DWI methods were compared by the paired t-test. The detectability of HCC on each DWI was also analyzed by three radiologists. The detectability provided by the two DWI methods was compared using McNemar's test. For all observers, the averaged image quality scores of FB-DWI were: Sharpness of the liver contour [observer (Obs)-1, 3.08 ± 0.81; Obs-2, 2.98 ± 0.73; Obs-3, 3.54 ± 0.75], those of the distortion (Obs-1, 2.94 ± 0.50; Obs-2, 2.71 ± 0.70; Obs-3, 3.27 ± 0.53), and the chemical shift artifacts (Obs-1, 3.38 ± 0.60; Obs-2, 3.15 ± 1.07; Obs-3, 3.21 ± 0.85). The averaged image quality scores of RT-DWI were: Sharpness of the liver contour (Obs-1, 2.33 ± 0.65; Obs-2, 2.37 ± 0.74; Obs-3, 2.75 ± 0.81), distortion (Obs-1, 2.81 ± 0.56; Obs-2, 2.25 ± 0.74; Obs-3, 2.96 ± 0.71), and the chemical shift artifacts (Obs-1, 2.92 ± 0.59; Obs-2, 2.21 ± 0.85; Obs-3, 2.77 ± 1.08). All image quality scores of FB-DWI were significantly higher than those of RT-DWI ( P < 0.05). The average SNR of the normal liver parenchyma by FB-DWI (11.0 ± 4.8) was not significantly different from that shown by RT-DWI (11.0 ± 5.0); nor were the lesion-to-nonlesion CNRs significantly different (FB-DWI, 21.4 ± 17.7; RT-DWI, 20.1 ± 15.1). For all three observers, the detectability of FB-DWI (Obs-1, 43.6%; Obs-2, 53.6%; and Obs-3, 45.0%) was significantly higher than that of RT-DWI (Obs-1, 29.1%; Obs-2, 43.6%; and Obs-3, 34.5%) ( P < 0.05). FB-DWI showed better image quality and higher detectability of HCC compared to RT-DWI, without significantly reducing the SNRs of the liver parenchyma and lesion-to-nonlesion CNRs.

Purpose: To evaluate the role of androgen deprivation therapy (ADT) and duration for high-risk prostate cancer patients treated with dose-escalated radiation therapy (RT). Methods and Materials: A retrospective analysis of high-risk prostate cancer patients treated with dose-escalated RT (minimum 75 Gy) with or without ADT was performed. The relationship between ADT use and duration with biochemical failure (BF), metastatic failure (MF), prostate cancer-specific mortality (PCSM), non-prostate cancer death (NPCD), and overall survival (OS) was assessed as a function of pretreatment characteristics, comorbid medical illness, and treatment using Fine and Gray's cumulative incidence methodology. Results: The median follow-up time was 64more » months. In men with National Comprehensive Cancer Network defined high-risk prostate cancer treated with dose-escalated RT, on univariate analysis, both metastasis (P<.0001; hazard ratio 0.34; 95% confidence interval 0.18-0.67; cumulative incidence at 60 months 13% vs 35%) and PCSM (P=.015; hazard ratio 0.41; 95% confidence interval 0.2-1.0; cumulative incidence at 60 months 6% vs 11%) were improved with the use of ADT. On multivariate analysis for all high-risk patients, Gleason score was the strongest negative prognostic factor, and long-term ADT (LTAD) improved MF (P=.002), PCSM (P=.034), and OS (P=.001). In men with prostate cancer and Gleason scores 8 to 10, on multivariate analysis after adjustment for other risk features, there was a duration-dependent improvement in BF, metastasis, PCSM, and OS, all favoring LTAD in comparison with STAD or RT alone. Conclusion: For men with high-risk prostate cancer treated with dose-escalated EBRT, this retrospective study suggests that the combination of LTAD and RT provided a significant improvement in clinical outcome, which was especially true for those with Gleason scores of 8 to 10.« less

Multi-institutional collaborations provide granularity lacking in epidemiologic datasets to enable in-depth study of rare diseases. For pts with superficial, high-grade soft tissue sarcomas (STS) of the trunk/extremity, the value of radiation therapy (RT) is not clear. We aimed to utilize the 7-institution US-Sarcoma-Collaborative (USSC) and the National Cancer Database (NCDB) to investigate this issue. All adult pts with superficial truncal/extremity high-grade STS who underwent primary curative-intent resection from 2000-2016 at USSC institutions or were included in the NCDB from 2004-2013 were analyzed. Propensity-score matching was performed. Endpoints were locoregional recurrence-free survival(LRFS), overall-survival(OS), and disease-specific survival(DSS). Of 4,153pts in the USSC, 169pts with superficial high-grade tumors underwent primary curative-intent resection, of whom 38% received RT. On multivariable Cox-regression analysis, RT was not associated with improved LRFS(p=0.56), OS(p=0.31), or DSS(p=0.20). On analysis of 51 propensity-score matched-pairs, RT was still not associated with increased LRFS, OS, or DSS. Analysis of 631 propensity-score matched-pairs in the NCDB demonstrated improved 5-yr OS associated with RT (80%vs70%;p=0.02). LRFS and DSS were not evaluable. Granular data afforded by collaborative research enables in-depth analysis of patient outcomes. The NCDB, although powered with large numbers, cannot assess many relevant outcomes (recurrence, DSS, or complications). In this study, the approaches yielded conflicting results. USSC data suggested no value of radiation while the NCDB demonstrated improved overall survival, contradicting all randomized-controlled trials in sarcoma. The pros/cons of either approach must be considered when applying results to clinical practice, and underscore the importance of randomized-controlled trials. Copyright © 2018.

Objective: To investigate the impact of including fluorine-18 fludeoxyglucose (18F-FDG) positron emission tomography (PET) scanning in the planning of paediatric radiotherapy (RT). Methods: Target volumes were first delineated without and subsequently re-delineated with access to 18F-FDG PET scan information, on duplicate CT sets. RT plans were generated for three-dimensional conformal photon RT (3DCRT) and intensity-modulated proton therapy (IMPT). The results were evaluated by comparison of target volumes, target dose coverage parameters, normal tissue complication probability (NTCP) and estimated risk of secondary cancer (SC). Results: Considerable deviations between CT- and PET/CT-guided target volumes were seen in 3 out of the 11 patients studied. However, averaging over the whole cohort, CT or PET/CT guidance introduced no significant difference in the shape or size of the target volumes, target dose coverage, irradiated volumes, estimated NTCP or SC risk, neither for IMPT nor 3DCRT. Conclusion: Our results imply that the inclusion of PET/CT scans in the RT planning process could have considerable impact for individual patients. There were no general trends of increasing or decreasing irradiated volumes, suggesting that the long-term morbidity of RT in childhood would on average remain largely unaffected. Advances in knowledge: 18F-FDG PET-based RT planning does not systematically change NTCP or SC risk for paediatric cancer patients compared with CT only. 3 out of 11 patients had a distinct change of target volumes when PET-guided planning was introduced. Dice and mismatch metrics are not sufficient to assess the consequences of target volume differences in the context of RT. PMID:25494657

Despite the improvement in radiotherapy (RT) technology, patients with nasopharyngeal carcinoma (NPC) still suffer from numerous distressing symptoms simultaneously during RT. The purpose of the study was to investigate the symptom clusters experienced by NPC patients during RT. First-treated Chinese NPC patients (n = 130) undergoing late-period RT (from week 4 till the end) were recruited for this cross-sectional study. They completed a sociodemographic and clinical data questionnaire, the Chinese version of the M. D. Anderson Symptom Inventory - Head and Neck Module (MDASI-HN-C) and the Chinese version of the Functional Assessment of Cancer Therapy - Head and Neck Scale (FACT-H&N-C). Principal axis factor analysis with oblimin rotation, independent t-test, one-way analysis of variance (ANOVA) and Pearson product-moment correlation were used to analyze the data. Four symptom clusters were identified, and labelled general, gastrointestinal, nutrition impact and social interaction impact. Of these 4 types, the nutrition impact symptom cluster was the most severe. Statistically positive correlations were found between severity of all 4 symptom clusters and symptom interference, as well as weight loss. Statistically negative correlations were detected between the cluster severity and the QOL total score and 3 out of 5 subscale scores. The four clusters identified reveal the symptom patterns experienced by NPC patients during RT. Future intervention studies on managing these symptom clusters are warranted, especially for the nutrition impact symptom cluster. Copyright © 2017 Elsevier Ltd. All rights reserved.

2016-09-01

There is a lack of data regarding maternal morbidity and neonatal hypoxia associated with shoulder dystocia (SD), particularly with respect to whether SD is managed with our without fetal manipulation (FM). Our main objective was to compare severe maternal and neonatal morbidities associated with SD according to FM execution. We conducted a retrospective study based on a medical record analysis that included all SD cases from 2007 to 2012. SD was considered when additional maneuvers were required to complete a delivery. Severe maternal morbidity was defined as the occurrence of an obstetric anal sphincter injury. Severe neonatal morbidity was defined as the occurrence of one of these complications: permanent brachial plexus palsy, arterial cord pH < 7.1, Apgar score < 7 at 5 min. We compared severe maternal and neonatal morbidities in the FM and the no-FM group. We report an SD incidence of 2.4 % (n = 227) with 93.8 % of patients treated without FM. We identified two cases of permanent brachial plexus palsy, fifteen cases of arterial cord pH < 7.1 and six cases with an Apgar score < 7 at 5 min; all of them were from the no-FM group. There were more cases of OASI in the FM group (odd ratio = 9.2 [1.32-50.71]). No statistical differences between these groups were observed with respect to severe neonatal morbidity. Severe neonatal morbidity does not appear to be associated with FM during SD management, but severe maternal morbidity is associated with FM execution.

Interventional Management of Stroke III did not show that combining IV recombinant tissue plasminogen activator (rt-PA) with endovascular therapies (EVTs) is better than IV rt-PA alone. To report efficacy and safety results for EVT of intracranial internal carotid artery (ICA) and middle cerebral artery trunk (M1) occlusion. Five revascularization methods for persistent occlusions after IV rt-PA treatment were evaluated for prespecified primary and secondary endpoints, after accounting for differences in key baselines variables using propensity scores. Revascularization was scored using the arterial occlusive lesion (AOL) and the modified Thrombolysis in Cerebral Ischemia (mTICI) scores. EVT of 200 subjects with intracranial ICA or M1 occlusion resulted in 81.5% AOL 2-3 recanalization, in addition to 76% mTICI 2-3 and 42.5% mTICI 2b-3 reperfusion. Adverse events included symptomatic intracranial hemorrhage (SICH) (8.0%), vessel perforations (1.5%), and new emboli (14.9%). EVT techniques used were standard microcatheter n=51; EKOS n=14; Merci n=77; Penumbra n=39; Solitaire n=4; multiple n=15. Good clinical outcome was associated with both TICI 2-3 and TICI 2b-3 reperfusion. Neither modified Rankin scale (mRS) 0-2 (28.5%), nor 90-day mortality (28.5%), nor asymptomatic ICH (36.0%) differed among revascularization methods after propensity score adjustment for subjects with intracranial ICA or M1 occlusion. Good clinical outcome was associated with good reperfusion for ICA and M1 occlusion. No significant differences in efficacy or safety among revascularization methods were demonstrated after adjustment. Lack of high-quality reperfusion, adverse events, and prolonged time to treatment contributed to lower-than-expected mRS 0-2 outcomes and study futility compared with IV rt-PA. NCT00359424.

To compare and contrast the patterns of failure in patients with locally advanced squamous cell oropharyngeal cancers undergoing curative-intent treatment with primary surgery or radiotherapy +/- chemotherapy. Two hundred and thirty-three patients with stage III or IV oropharyngeal squamous cell carcinoma who underwent curative-intent treatment from 2006-2012, were reviewed. The median length of follow-up for patients still alive at the time of analysis was 4.4 years. Data was collected retrospectively from a chart review. One hundred and thirty-nine patients underwent primary surgery +/- adjuvant therapy, and 94 patients underwent primary radiotherapy +/- chemotherapy (CRT). Demographics were similar between the two groups, except primary radiotherapy patients had a higher age-adjusted Charleston co-morbidity score (CCI). Twenty-nine patients from the surgery group recurred; 15 failed distantly only, seven failed locoregionally, and seven failed both distantly and locoregionally. Twelve patients recurred who underwent chemoradiotherapy; ten distantly alone, and two locoregionally. One patient who underwent radiotherapy (RT) alone failed distantly. Two and five-year recurrence-free survival rates for patients undergoing primary RT were 86.6% and 84.9% respectively. Two and five-year recurrence-free survival rates for primary surgery was 80.9% and 76.3% respectively (p=0.21). There was no significant difference in either treatment when they were stratified by p16 status or smoking status. Our analysis does not show any difference in outcomes for patients treated with primary surgery or radiotherapy. Although the primary pattern of failure in both groups was distant metastatic disease, some local failures may be preventable with careful delineation of target volumes, especially near the base of skull region.

Resistance training (RT) is emerging as a training modality to improve motor function and facilitate physical activity participation in children across the motor proficiency spectrum. Although RT competency assessments have been established and validated among adolescent cohorts, the extent to which these methods are suitable for assessing children's RT skills is unknown. This project aimed to assess the psychometric properties of the adapted Resistance Training Skills Battery for Children (RTSBc), in children with varying motor proficiency. Repeated measures design with 40 participants (M age=8.2±1.7years) displaying varying levels of motor proficiency. Participants performed the adapted RTSBc on two occasions, receiving a score for their execution of each component, in addition to an overall RT skill quotient child (RTSQc). Cronbach's alpha, intra-class correlation (ICC), Bland-Altman analysis, and typical error were used to assess test-retest reliability. To examine construct validity, exploratory factor analysis was performed alongside computing correlations between participants' muscle strength, motor proficiency, age, lean muscle mass, and RTSQc. The RTSBc displayed an acceptable level of internal consistency (alpha=0.86) and test-retest reliability (ICC range=0.86-0.99). Exploratory factor analysis supported internal test structure, with all six RT skills loading strongly on a single factor (range 0.56-0.89). Analyses of structural validity revealed positive correlations for RTSQc in relation to motor proficiency (r=0.52, p<0.001) and strength scores (r=0.61, p<0.001). Analyses revealed support for the construct validity and test-retest reliability of the RTSBc, providing preliminary evidence that the RTSBc is appropriate for use in the assessment of children's RT competency.

Background and Purpose Sex and race reportedly influence outcome after recombinant tissue-type plasminogen activator (rtPA). It is, however, unclear whether baseline imbalances (eg, stroke severity) or lack of response to thrombolysis is responsible. We applied balancing methods to test the hypothesis that race and sex influence outcome after rtPA independent of baseline conditions. Methods We mapped group outcomes from the National Institute of Neurological Disorders and Stroke (NINDS) dataset based on race and sex onto a surrogate-control function to assess differences from expected outcomes at their respective National Institutes of Health Stroke Scale and age. Outcomes were also compared for subjects matched individually on key baseline factors using NINDS and 2 recent datasets from southeastern United States. Results At similar National Institutes of Health Stroke Scale and age, 90-day good outcomes (modified Rankin Score, 0–2) in NINDS were similarly improved after rtPA for white men and women. There was a strong trend for improvement in black men. Conversely, black women treated with rtPA showed response rates no different from the controls. After baseline matching, there were nonsignificant trends in outcomes except for significantly fewer good outcomes in black versus matched white women (37% versus 63%; P=0.027). Pooling the 3 datasets showed a similar trend for poorer short-term outcome for black women (P=0.054; modified Rankin Score, 0–1). Conclusions Matching for key baseline factors indicated that race and sex influence outcome most strikingly in black women who demonstrated poorest outcomes after rtPA. This finding supports the hypothesis that poor response to rtPA, rather than differences in baseline conditions, contributes to the worse outcome. This finding requires prospective confirmation.

Radiotherapy-induced xerostomia (RIX) is the most common permanent side effect of radiotherapy (RT) to the head and neck (H&N). There is no effective topical treatment. LMS-611 is a mimetic of a natural lamellar body which prevents thick secretions like saliva from congesting organs. The primary objective of this study was to assess saliva properties before and during RT to the H&N. The secondary objectives were to re-assess saliva properties with the addition of LMS-611, measure inter-patient variability, correlate patient-reported symptoms with laboratory measurements and design subsequent first-in-human clinical trial of LMS-611. Patients with H&N cancer receiving RT as primary treatment were recruited. Patients completed the Groningen RIX (GRIX) questionnaire and provided saliva samples at baseline and weeks 2, 4 and 6 of RT. Saliva adhesiveness and viscosity were tested by measuring time taken to travel 5 cm down an inclined plane. Thirty patients were enrolled. The inclined plane test (IPT) results (s) were as follows: baseline 31.3, week 2 49.7, week 4 51.1 and week 6 55.7. Wide inter-patient variability was seen at baseline. GRIX scores increased as RT progressed. Spearman rank correlation coefficient of inclined plane tests with GRIX scores was -0.06 at baseline, 0.25 at week 2, 0.12 at week 4 and 0.08 at week 6. LMS-611 concentrations of 10 and 20 mg/ml significantly reduced IPT times on saliva samples. Saliva becomes more visco-adhesive and RIX worsens as RT progresses. There is little correlation between objective and subjective measures of RIX. The addition of LMS-611 to thick, sticky saliva restores its fluidity ex vivo. This warrants in vivo analysis of the effect of LMS-611 upon RIX.

The aim of the present study is to assess the disease profile, outcome and prognostic factors in patients treated with surgery combined with radiotherapy (RT), with or without chemotherapy (CXT), for soft-tissue sarcoma (STS) in a multidisciplinary setting. One hundred and sixty-four patients with STS treated between 1980 and 2010 at the Centre Hospitalier Universitaire Vaudois were enrolled in this retrospective study. Seventy-six percent of patients underwent postoperative RT with (24%), or without (52%) CXT, 15% preoperative RT with (5%), or without (10%) CXT, surgery alone (7%), or RT alone (2%) with or without CXT. The median follow-up was 60 months (range 6-292). Local failure was observed in 18%, and distant failure in 21% of the patients. Overall survival (OS), diseasefree survival (DFS), local control (LC) and distant metastases-free survival (DMFS) were 88%, 68%, 83%, and 79% at 5 years, and 80%, 56%, 76%, and 69% at 10 years, respectively. In univariate analyses, favorable prognostic factors for OS, DFS, and DMFS were tumor size 6 cm or less, World Health Organization (WHO)/Zubrod score 0, and stage 2 or less. Age and superficial tumors were favorable only for OS and DMFS respectively. STS involving the extremities had a better outcome regarding DFS and LC. Histological grade 2 or less was favorable for DFS, DMFS, and LC. Radical surgery was associated with better LC and DMFS. RT dose more than 60 Gy was favorable for OS, DFS, and LC. In multivariate analyses, independent factors were age for OS; tumor size for OS, DFS and DMFS; WHO/Zubrod score for OS, DFS and LC; hemoglobin level for DFS; site for DFS and LC; tumor depth for DMFS; histological grade for DFS and LC; surgical procedure for LC and DMFS; and RT dose for OS. This study confirms that in a multidisciplinary setting, STS have a fairly good prognosis. A number of prognostic and predictive factors, including the role of surgery combined with RT, were identified. Regarding RT, a dose of more than 60 Gy was associated with a better outcome, at the price of a higher toxicity. We could not demonstrate a superiority of preoperative RT over postoperative RT.

Influenza challenge trials are important for vaccine efficacy testing. Currently, disease severity is determined by self-reported scores to a list of symptoms which can be highly subjective. A more objective measure would allow for improved data analysis. Twenty-one volunteers participated in an influenza challenge trial. We calculated the daily sum of scores (DSS) for a list of 16 influenza symptoms. Whole blood collected at baseline and 24, 48, 72 and 96 h post challenge was profiled on Illumina HT12v4 microarrays. Changes in gene expression most strongly correlated with DSS were selected to train a Random Forest model and tested on two independent test sets consisting of 41 individuals profiled on a different microarray platform and 33 volunteers assayed by qRT-PCR. 1456 probes are significantly associated with DSS at 1% false discovery rate. We selected 19 genes with the largest fold change to train a random forest model. We observed good concordance between predicted and actual scores in the first test set (r = 0.57; RMSE = -16.1%) with the greatest agreement achieved on samples collected approximately 72 h post challenge. Therefore, we assayed samples collected at baseline and 72 h post challenge in the second test set by qRT-PCR and observed good concordance (r = 0.81; RMSE = -36.1%). We developed a 19-gene qRT-PCR panel to predict DSS, validated on two independent datasets. A transcriptomics based panel could provide a more objective measure of symptom scoring in future influenza challenge studies. Trial registration Samples were obtained from a clinical trial with the ClinicalTrials.gov Identifier: NCT02014870, first registered on December 5, 2013.

Purpose: To describe the quality of life (QOL) in elderly patients with glioblastoma (GBM) treated with an abbreviated course of radiation therapy (RT; 40 Gy in 15 fractions) plus concomitant and adjuvant temozolomide (TMZ). Methods and Materials: Health-related QOL (HRQOL) was assessed by European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30, version 3) and EORTC Quality of Life Questionnaire Brain Cancer Module (QLQ-BN20). Changes from baseline in the score of 9 preselected domains (global QLQ, social functioning, cognitive functioning, emotional functioning, physical functioning, motor dysfunction, communication deficit, fatigue, insomnia) were determined 4 weeksmore » after RT and thereafter every 8 weeks during the treatment until disease progression. The proportion of patients with improved HRQOL scores, defined as a change of 10 points or more, and duration of changes were recorded. Results: Sixty-five patients completed the questionnaires at baseline. The treatment was consistently associated with improvement or stability in most of the preselected HRQOL domains. Global health improved over time; mean score differed by 9.6 points between baseline and 6-month follow-up (P=.03). For social functioning and cognitive functioning, mean scores improved over time, with a maximum difference of 10.4 points and 9.5 points between baseline and 6-month follow-up (P=.01 and P=.02), respectively. By contrast, fatigue worsened over time, with a difference in mean score of 5.6 points between baseline and 4-month follow-up (P=.02). Conclusions: A short course of RT in combination with TMZ in elderly patients with GBM was associated with survival benefit without a negative effect on HRQOL until the time of disease progression.« less

Objectives: The aim of this study was to assess the psychological health of first-year health professional students and to study sources of student stress. Methods: All first-year students (N = 125) of the Gulf Medical University (GMU) in Ajman, United Arab Emirates (UAE), were invited to participate in a voluntary, anonymous, self-administered, questionnaire-based survey in January 2011. Psychological health was assessed using the 12-item General Health Questionnaire. A 24-item questionnaire, with items related to academic, psychosocial and health domains was used to identify sources of stress. Pearson’s chi-squared test and the Mann-Whitney U-test were used for testing the association between psychological morbidity and sources of stress. Results: A total of 112 students (89.6%) completed the survey and the overall prevalence of psychological morbidity was found to be 33.6%. The main academic-related sources of stress were ‘frequency of exams’, ‘academic workload’, and ‘time management’. Major psychosocial stressors were ‘worries regarding future’, ‘high parental expectations’, ‘anxiety’, and ‘dealing with members of the opposite sex’. Health-related issues were ‘irregular eating habits’, ‘lack of exercise’, and ‘sleep-related problems’. Psychological morbidity was not significantly associated with any of the demographic factors studied. However, total stress scores and academics-related domain scores were significantly associated with psychological morbidity. Conclusion: Psychological morbidity was seen in one in three first-year students attending GMU. While worries regarding the future and parental expectations were sources of stress for many students, psychological morbidity was found to be significantly associated with only the total stress and the academic-related domain scores.

To assess factors associated with morbidity and mortality following the use of robotics in general surgery. Case series. University of Illinois at Chicago. Eight hundred eighty-four consecutive patients who underwent a robotic procedure in our institution between April 2007 and July 2010. Perioperative morbidity and mortality. During the study period, 884 patients underwent a robotic procedure. The conversion rate was 2%, the mortality rate was 0.5%, and the overall postoperative morbidity rate was 16.7%. The reoperation rate was 2.4%. Mean length of stay was 4.5 days (range, 0.2-113 days). In univariate analysis, several factors were associated with increased morbidity and included either patient-related (cardiovascular and renal comorbidities, American Society of Anesthesiologists score ≥ 3, body mass index [calculated as weight in kilograms divided by height in meters squared] <30, age ≥ 70 years, and malignant disease) or procedure-related (blood loss ≥ 500 mL, transfusion, multiquadrant operation, and advanced procedure) factors. In multivariate analysis, advanced procedure, multiquadrant surgery, malignant disease, body mass index of less than 30, hypertension, and transfusion were factors significantly associated with a higher risk for complications. American Society of Anesthesiologists score of 3 or greater, age 70 years or older, cardiovascular comorbidity, and blood loss of 500 mL or more were also associated with increased risk for mortality. Use of the robotic approach for general surgery can be achieved safely with low morbidity and mortality. Several risk factors have been identified as independent causes for higher morbidity and mortality. These can be used to identify patients at risk before and during the surgery and, in the future, to develop a scoring system for the use of robotic general surgery

Objectives The goal of cartilage repair techniques such as microfracture (MFX) or matrix-associated autologous chondrocyte transplantation (MACT) is to produce repair tissue (RT) with sufficient glycosaminoglycan (GAG) content. Sodium magnetic resonance imaging (MRI) offers a direct and noninvasive evaluation of the GAG content in native cartilage and RT. In the femoral cartilage, this method was able to distinguish between RTs produced by MFX and MACT having different GAG contents. However, it needs to be clarified whether sodium MRI can be useful for evaluating RT in thin ankle cartilage. Thus, the aims of this 7-T study were (1) to validate our sodium MRI protocol in cadaver ankle samples, (2) to evaluate the sodium corrected signal intensities (cSI) in cartilage of volunteers, (3) and to compare sodium values in RT between patients after MFX and MACT treatment. Materials and Methods Five human cadaver ankle samples as well as ankles of 9 asymptomatic volunteers, 6 MFX patients and 6 MACT patients were measured in this 7-T study. Sodium values from the ankle samples were compared with histochemically evaluated GAG content. In the volunteers, sodium cSI values were calculated in the cartilages of ankle and subtalar joint. In the patients, sodium cSI in RT and reference cartilage were measured, morphological appearance of RT was evaluated using the magnetic resonance observation of cartilage repair tissue (MOCART) scoring system, and clinical outcome before and after surgery was assessed using the American Orthopaedic Foot and Ankle Society score and Modified Cincinnati Knee Scale. All regions of interest were defined on morphological images and subsequently transferred to the corresponding sodium images. Analysis of variance, t tests, and Pearson correlation coefficients were evaluated. Results In the patients, significantly lower sodium cSI values were found in RT than in reference cartilage for the MFX (P = 0.007) and MACT patients (P = 0.008). Sodium cSI and MOCART scores in RT did not differ between the MFX and MACT patients (P = 0.185). No significant difference in sodium cSI was found between reference cartilage of the volunteers and the patients (P = 0.355). The patients showed significantly higher American Orthopaedic Foot and Ankle Society and Modified Cincinnati scores after treatment than they did before treatment. In the volunteers, sodium cSI was significantly higher in the tibial cartilage than in the talar cartilage of ankle joint (P = 0.002) and in the talar cartilage than in the calcaneal cartilage of subtalar joint (P < 0.001). Data from the cadaver ankle samples showed a strong linear relationship between the sodium values and the histochemically determined GAG content (r = 0.800; P < 0.001; R2 = 0.639). Conclusions This study demonstrates the feasibility of in vivo quantification of sodium cSI, which can be used for GAG content evaluation in thin cartilages of ankle and subtalar joints at 7 T. A strong correlation observed between the histochemically evaluated GAG content and the sodium values proved the sufficient sensitivity of sodium MRI to changes in the GAG content of cartilages in the ankle. Both MFX and MACT produced RT with lower sodium cSI and, thus, of lower quality compared with reference cartilage in the patients or in the volunteers. Our results suggest that MFX and MACT produce RT with similar GAG content and similar morphological appearance in patients with similar surgery outcome. Sodium MRI at 7 T allows a quantitative evaluation of RT quality in the ankle and may thus be useful in the noninvasive assessment of new cartilage repair procedures. PMID:25436618

The Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) focus is on randomized trials of different approaches to mass drug administration (MDA) in endemic countries in Africa. Because their studies provided an opportunity to evaluate the effects of mass treatment on Schistosoma-associated morbidity, nested cohort studies were developed within SCORE's intervention trials to monitor changes in a suite of schistosomiasis disease outcomes. This paper describes the process SCORE used to select markers for prospective monitoring and the baseline prevalence of these morbidities in four parallel cohort studies. In July 2009, SCORE hosted a discussion of the potential impact of MDA on morbidities due to Schistosoma infection that might be measured in the context of multi-year control. Candidate markers were reviewed and selected for study implementation. Baseline data were then collected from cohorts of children in four country studies: two in high endemic S. mansoni sites (Kenya and Tanzania), and two in high endemic S. haematobium sites (Niger and Mozambique), these cohorts to be followed prospectively over 5 years. At baseline, 62% of children in the S. mansoni sites had detectable eggs in their stool, and 10% had heavy infections (≥ 400 eggs/g feces). Heavy S. mansoni infections were found to be associated with increased baseline risk of anemia, although children with moderate or heavy intensity infections had lower risk of physical wasting. Prevalence of egg-positive infection in the combined S. haematobium cohorts was 27%, with 5% of individuals having heavy infection (≥50 eggs/10 mL urine). At baseline, light intensity S. haematobium infection was associated with anemia and with lower scores in the social domain of health-related quality-of-life (HRQoL) assessed by Pediatric Quality of Life Inventory. Our consensus on practical markers of Schistosoma-associated morbidity indicated that height, weight, hemoglobin, exercise tolerance, HRQoL, and ultrasound abnormalities could be used as reference points for gauging treatment impact. Data collected over five years of program implementation will provide guidance for future evaluation of morbidity control in areas endemic for schistosomiasis. These cohort studies are registered and performed in conjunction with the International Standard Randomised Controlled Trial Registry trials ISRCTN16755535 , ISRCTN14117624 , ISRCTN95819193 , and ISRCTN32045736 .

Purpose: To examine the impact of patient, disease, and treatment characteristics on survival outcomes in patients treated with neoadjuvant androgen deprivation therapy (ADT) and radical external-beam radiotherapy (RT) for clinically localized, extreme-risk prostate adenocarcinoma with a presenting prostate-specific antigen (PSA) concentration of >40 ng/ml. Methods and Materials: A retrospective chart review was conducted of 64 patients treated at a single institution between 1991 and 2000 with ADT and RT for prostate cancer with a presenting PSA level of >40 ng/ml. The effects of patient age, tumor (presenting PSA level, Gleason score, and T stage), and treatment (total ADT duration andmore » pre-RT PSA level) characteristics on rates of biochemical disease-free survival (bDFS), prostate cancer-specific survival (PCSS), and overall survival (OS) were examined. Results: Median follow-up time was 6.45 years (range, 0.09-15.19 years). Actuarial bDFS, PCSS, and OS rates at 5 years were 39%, 87%, and 78%, respectively, and 17%, 64%, and 45%, respectively, at 10 years. On multivariate analysis, the pre-RT PSA level ({<=}0.1 versus >0.1 ng/ml) was the single most significant prognostic factor for bDFS (p = 0.033) and OS (p = 0.018) rates, whereas age, T stage, Gleason score, and ADT duration ({<=}6 versus >6 months) were not predictive of outcomes. Conclusion: In prostate cancer patients with high presenting PSA levels, >40 ng/ml, treated with combined modality, neoadjuvant ADT, and RT, the pre-RT PSA nadir, rather than ADT duration, was significantly associated with improved survival. This observation supports the use of neoadjuvant ADT to drive PSA levels to below 0.1 ng/ml before initiation of RT, to optimize outcomes for patients with extreme-risk disease.« less

Background There have not yet been any published studies on the effects of laughter therapy on radiation-induced dermatitis in breast cancer patients treated with radiotherapy (RT). We assessed the effectiveness of laughter therapy in preventing radiation dermatitis in patients with breast cancer. Methods Thirty-seven patients were prospectively enrolled in this study. Eighteen patients were assigned to the experimental group and the other 19 patients were assigned to the control group. The patients who were assigned to the experimental group received laughter therapy during RT. Laughter therapy was started at the onset of RT and was provided twice a week until completion of RT. The patients who were assigned to the control group only received RT without laughter therapy. The grade of radiation dermatitis was scored by a radiation oncologist who was blinded to subject assignment. The patients’ evaluation of pain within the RT field was also assessed. Results In the experimental group, radiation dermatitis of grade 3, 2, and 1 developed in five (33.3%), five (33.3%), and five patients (33.3%), respectively. In comparison, in the control group, radiation dermatitis of grade 3, 2, 1, and 0 developed in seven (36.8%), nine (47.4%), two (10.5%), and one patient (5.3%), respectively. The experimental group exhibited a lower incidence of grade 2 or worse radiation dermatitis than the control group (33.3% versus 47.4%). The mean maximal pain scores in the experimental and control group were 2.53 and 3.95, respectively. The experimental group complained of less severe pain than the control group during RT. However, these differences were not statistically significant. Conclusion The results of this study show that laughter therapy can have a beneficial role in preventing radiation dermatitis in patients with breast cancer. To confirm the results of our study, well-designed randomized studies with large sample sizes are required. PMID:25395864

We changed the primary oropharynx squamous cell carcinoma (OPSCC) treatment recommendation from primary radiation therapy (RT) to tumor surgery and neck dissection, followed by RT around the year 2000 with apparently improved survival. However, high-risk human papilloma virus (hr-HPV)-16-caused OPSCCs have increased during this period. Furthermore, hr-HPV+ OPSCC carry a better prognosis than hr-HPV-negative patients. We have, therefore, evaluated the 5-year survival in the period from 1992 to 1999 versus 2000 to 2008 stratified by hr-HPV tumor infection status. Ninety-six OPSCC patients were treated from 1992 to 1999 compared with 136 patients from 2000 to 2008. The 5-year disease-specific survival (DDS) and overall survival (OS) were recorded, while the health-related quality of life (HRQoL) scores were obtained from some of the cured patients. Thirty-eight (40 %) in the first period and 86 OPSCCs (63 %) in the second period were hr-HPV+. In the first period, 16 versus 62 patients in the last period were treated by neck dissection, primary tumor surgery, and RT. DSS among all the hr-HPV-negative patients in the first period was 51 versus 55 % in the second period, and the corresponding OS was 33 versus 31 %, respectively. The DSS among all the hr-HPV+ patients was 78 % in the first period versus 77 % in the second period, while the OS was 71 versus 69 %, respectively. The HRQoL scores among successfully treated patients were worse following surgery, plus RT than RT only. The hr-HPV-adjusted 5-year survival in OPSCC patients was similar between the two time periods. A decreased HRQoL was associated with surgical therapy, which indicates that hr-HPV+ OPSCC patients may be treated by primary RT followed by major surgery only if RT treatment fails.

To evaluate the efficacy and safety of carbon-ion radiation therapy (RT) for mucosal melanoma of the head and neck (MMHN) in the Japan Carbon-Ion Radiation Oncology Study Group study. Patients with MMHN with N0-1M0 status who were treated with carbon-ion RT at 4 institutions in Japan between November 2003 and December 2014 were analyzed retrospectively. Two hundred sixty patients (male, 111; female, 149; median age, 68 years) with histologically proven MMHN were enrolled. Primary sites included the nasal cavity in 178 patients, paranasal sinuses in 43, oral cavity in 27, and pharynx in 12. Eighty-six patients had T3 tumors, 147 had T4a tumors, and 27 had T4b tumors. Two hundred fifty-one patients were diagnosed with N0 disease, and 9 with N1 disease. The median total dose and number of fractions were 57.6 Gy RBE (relative biological effectiveness) and 16, respectively. Chemotherapy including dimethyl traizeno imidazole carboxamide was used concurrently in 129 patients. The median follow-up duration was 22 months (range, 1-132 months). The 2-year overall survival and local control rates were 69.4% and 83.9%, respectively. Multivariate analysis showed that gross tumor volume and concurrent chemotherapy were significant prognostic factors for overall survival. Grade 3 and grade 4 late morbidities were observed in 27 and 7 patients (5 developed ipsilateral blindness, 1 mucosal ulcer, and 1 second malignant disease in the irradiated volume), respectively. No patients developed grade 5 late morbidities. Carbon-ion RT is a promising treatment option for MMHN. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

To perform a systematic review to investigate the optimal treatment strategy among the options of surgery alone, radiotherapy (RT) alone, and the combination of RT plus surgery in the management of localized Ewing's sarcoma of bone following neo-adjuvant chemotherapy. MEDLINE and EMBASE (1999 to February 2015), the Cochrane Library, and relevant conferences were searched. Two systematic reviews and eight full texts met the pre-planned study selection criteria. When RT was compared with surgery, a meta-analysis combining two papers showed that surgery resulted in a higher event-free survival (EFS) than RT in any location (HR = 1.50, 95% CI 1.12-2.00; p = 0.007). However another paper did not find a statistically significant difference in patients with pelvic disease, and no papers identified a significant difference in overall survival. When surgery plus RT was compared with surgery alone, a meta-analysis did not demonstrate a statistically significant difference for EFS between the two groups (HR = 1.21, 95% CI 0.90-1.63). Both surgical morbidities and radiation toxicities were reported. The existing evidence is based on very low aggregate quality as assessed by the GRADE approach. In patients with localized Ewing's sarcoma, either surgery alone (if complete surgical excision with clear margin can be achieved) or RT alone may be a reasonable treatment option. The optimal local treatment for an individual patient should be decided through consideration of patient characteristics, the potential benefit and harm of the treatment options, and patient preference.

2017-12-01

Spontaneous mentalizing ability has been linked to symptoms severity in individuals with autism spectrum disorder (ASD). Here we investigated whether in neurotypicals, higher levels of ASD symptomatology could also be linked to lower levels of spontaneous mentalizing, by comparing neurotypicals scoring high with those scoring low on the short Autism Spectrum Quotient. Participants watched movies during which they, and another agent, formed beliefs about the location of an object. These beliefs could influence reaction times (RT) to that object in the outcome phase. We expected participants with more ASD symptoms to show less spontaneous mentalizing, as reflected by a smaller effect of the other agent's beliefs on RT patterns (the ToM index). In contrast, the effect of own beliefs on RTs, reflecting an egocentric bias, was expected to be larger in the high-scoring group. Results showed that groups differed in the effect of the agent's beliefs; the ToM index was highly significant in the low-scoring group, while being absent in the high-scoring group. No difference in egocentric bias was observed. These findings suggest that the relationship between levels of ASD symptomatology and spontaneous mentalizing is not only present in individuals with ASD, but also in the neurotypical population.

Bone metastases cause pain, suffering and impaired quality of life (QoL). Palliative radiotherapy (RT) and/or chemotherapy are effective methods in controlling pain, reducing analgesics use and improving QoL. This study goal was to investigate the changes in QoL scores among patients who responded to palliative treatment. A prospective study evaluating the role of radiation therapy in a public academic hospital in São Paulo-Brazil recorded patients' opioid use, pain score, Portuguese version of QLQ-BM22 and QLQ-C30 before and 2 months after radiotherapy. Analgesic use and pain score were used to calculate international pain response category. Overall response was defined as the sum of complete response (CR) and partial response (PR). CR was defined as pain score of 0 with no increase in analgesic intake whereas PR was defined as pain reduction ≥2 without analgesic increase or analgesic reduction in ≥25% without increase in pain at the treated site. From September 2014 to October 2015, 25 patients with bone metastases responded to RT or chemotherapy (1 CR, 24 PR). There were 8 male and 17 female patients. The median age of the 25 patients was 59 (range, 22 to 80) years old. Patient's primary cancer site was breast [11], prostate [5], lung [2], others [7]. For QLQ-BM 22, the mean scores of 4 categories at baseline were: pain site (PS) 39, pain characteristics (PC) 61, function interference (FI) 49 and psycho-social aspects (PA) 57. At 2 month follow up, the scores were PS 27, PC 37, FI 70 and PA 59. Statistical significant improvement (P<0.05) was seen in PS, PC, FI but not PA. In the QLQ-C30, the scores were not statistically different for all categories, except for pain that demonstrated a 33 point decrease in the median pain score domain (66 to 33). Responders to RT at 2 months presented improvement in BM22 and C30 pain domains, and also improvement in functional interference domain of the BM22 questionnaire.

An 8-gene qRT-PCR-based gene expression score that has prognostic value in early breast cancer

PubMed Central

2010-01-01

Background Gene expression profiling may improve prognostic accuracy in patients with early breast cancer. Our objective was to demonstrate that it is possible to develop a simple molecular signature to predict distant relapse. Methods We included 153 patients with stage I-II hormonal receptor-positive breast cancer. RNA was isolated from formalin-fixed paraffin-embedded samples and qRT-PCR amplification of 83 genes was performed with gene expression assays. The genes we analyzed were those included in the 70-Gene Signature, the Recurrence Score and the Two-Gene Index. The association among gene expression, clinical variables and distant metastasis-free survival was analyzed using Cox regression models. Results An 8-gene prognostic score was defined. Distant metastasis-free survival at 5 years was 97% for patients defined as low-risk by the prognostic score versus 60% for patients defined as high-risk. The 8-gene score remained a significant factor in multivariate analysis and its performance was similar to that of two validated gene profiles: the 70-Gene Signature and the Recurrence Score. The validity of the signature was verified in independent cohorts obtained from the GEO database. Conclusions This study identifies a simple gene expression score that complements histopathological prognostic factors in breast cancer, and can be determined in paraffin-embedded samples.

Edaravone, a free radical scavenger, alleviates blood-brain barrier disruption in conjunction with suppression of the inflammatory reaction in acute cerebral infarction. Thrombolysis with recombinant tissue plasminogen activator (rtPA) is an established therapy for acute cerebral infarction patients. The purpose of this study was to assess the effects of edaravone on outcomes in acute cerebral infarction patients treated with ultra-early thrombolysis of iv-rt-PA. We conducted a retrospective cohort study using the database of Ningbo First Hospital. We identified patients who were admitted with a primary diagnosis of acute cerebral infarction and treated with intravenous rtPA(iv-rtPA) within 3 h of symptom onset from March 1st in 2014 to October 31st in 2016.Thenceforth,the patients were divided into 2 groups by treatment with(edaravone group) or without edaravone(non-edaravone group). Glasgow Coma Scale (GCS) scores and mRS score at admission were used. Clinical background, risk factors for acute cerebral infarction hemorrhagic transformation, 7-day mortality, recanalization rate, bleeding complications and blood rheology indexes were collected. We also collected the following factors: National Institutes of Health Stroke Scale scores, barthel index. 136 patients treated without edaravone during hospitalization were selected in non-edaravone group while edaravone group included 132 patients treated with edaravone during hospitalization. The patient baseline distributions were well balanced between non-edaravone group and edaravone group. The rate of hemorrhagic transformation in non-edaravone group was higher than that in edaravone group (P ＜ 0.05). The NIHSS scores 7 days and 14 days after symptom onset were higher in non-edaravone group than in edaravone group (both P ＜ 0.05). Edaravone group showed a higher recanalization rate and a lower bleeding complications rate at discharge than the non-edaravone group (both P ＜ 0.05). The differences of all the blood rheology indexes between the two groups were statistically significant (all P ＜ 0.05). Edaravone may improve outcomes of acute cerebral infarction patients treated with ultra-early thrombolysis of iv-rt-PA. Copyright © 2018 Elsevier B.V. All rights reserved.

Validation of a new algorithm for a quick and easy RT-PCR-based ALK test in a large series of lung adenocarcinomas: Comparison with FISH, immunohistochemistry and next generation sequencing assays.

Anaplastic Lymphoma Kinase (ALK) gene rearrangements have been described in 3-5% of lung adenocarcinomas (ADC) and their identification is essential to select patients for treatment with ALK tyrosine kinase inhibitors. For several years, fluorescent in situ hybridization (FISH) has been considered as the only validated diagnostic assay. Currently, alternative methods are commercially available as diagnostic tests. A series of 217 ADC comprising 196 consecutive resected tumors and 21 ALK FISH-positive cases from an independent series of 702 ADC were investigated. All specimens were screened by IHC (ALK-D5F3-CDx-Ventana), FISH (Vysis ALK Break-Apart-Abbott) and RT-PCR (ALK RGQ RT-PCR-Qiagen). Results were compared and discordant cases subjected to Next Generation Sequencing. Thirty-nine of 217 samples were positive by the ALK RGQ RT-PCR assay, using a threshold cycle (Ct) cut-off ≤35.9, as recommended. Of these positive samples, 14 were negative by IHC and 12 by FISH. ALK RGQ RT-PCR/FISH discordant cases were analyzed by the NGS assay with results concordant with FISH data. In order to obtain the maximum level of agreement between FISH and ALK RGQ RT-PCR data, we introduced a new scoring algorithm based on the ΔCt value. A ΔCt cut-off level ≤3.5 was used in a pilot series. Then the algorithm was tested on a completely independent validation series. By using the new scoring algorithm and FISH as reference standard, the sensitivity and the specificity of the ALK RGQ RT-PCR(ΔCt) assay were 100% and 100%, respectively. Our results suggest that the ALK RGQ RT-PCR test could be useful in clinical practice as a complementary assay in multi-test diagnostic algorithms or even, if our data will be confirmed in independent studies, as a standalone or screening test for the selection of patients to be treated with ALK inhibitors.

Purpose: This phase 2 study evaluated the efficacy of radiation therapy (RT) with concurrent and sequential sorafenib therapy in patients with unresectable hepatocellular carcinoma (HCC). Methods and Materials: Forty patients with unresectable HCC unfit for transarterial chemoembolization were treated with RT with concurrent and sequential sorafenib. Sorafenib was administered from the commencement of RT at a dose of 400 mg twice daily and continued to clinical or radiologic progression, unacceptable adverse events, or death. All patients had underlying Child-Pugh A cirrhosis. The maximal tumor diameter ranged from 3.0 cm to 15.5 cm. Coexisting portal vein thrombosis was found in 24 patients and wasmore » irradiated simultaneously. The cumulative RT dose ranged from 40 Gy to 60 Gy (median, 50 Gy). Image studies were done 1 month after RT and then every 3 months thereafter. Results: Thirty-three (83%) completed the allocated RT. During RT, the incidence of hand-foot skin reactions ≥ grade 2 and diarrhea were 37.5% and 25%, respectively, and 35% of patients had hepatic toxicities grade ≥2. Twenty-two (55.0%) patients achieved complete or partial remission at the initial assessment, and 18 (45%) had stable or progressive disease. The 2-year overall survival and infield progression-free survival (IFPS) were 32% and 39%, respectively. A Cancer of the Liver Italian Program (CLIP) score ≥2 was associated with an inferior outcome in overall survival. Six patients (15%) developed treatment-related hepatic toxicity grade ≥3 during the sequential phase, and 3 of them were fatal. Conclusions: When RT and sorafenib therapy were combined in patients with unresectable HCC, the initial complete or partial response rate was 55% with a 2-year IFPS of 39%. A CLIP score ≥2 was associated with an inferior outcome in overall survival. Hepatic toxicities are a major determinant of the safety; the combination should be used with caution and needs further investigation.« less

Resistance training (RT) and increased dietary protein are recommended to attenuate age-related muscle loss in the elderly. This study examined the effect of a lean red meat protein-enriched diet combined with progressive resistance training (RT+Meat) on health-related quality of life (HR-QoL) in elderly women. In this 4-month cluster randomised controlled trial, 100 women aged 60-90 years (mean 73 years) from self-care retirement villages participated in RT twice a week and were allocated either 160 g/d (cooked) lean red meat consumed across 2 meals/d, 6 d/week or ≥1 serving/d (25-30 g) carbohydrates (control group, CRT). HR-QoL (SF-36 Health Survey questionnaire), lower limb maximum muscle strength and lean tissue mass (LTM) (dual-energy X-ray absorptiometry) were assessed at baseline and 4 months. In all, ninety-one women (91 %) completed the study (RT+Meat (n 48); CRT (n 43)). Mean protein intake was greater in RT+Meat than CRT throughout the study (1·3 (sd 0·3) v. 1·1 (sd 0·3) g/kg per d, P<0·05). Exercise compliance (74 %) was not different between groups. After 4 months there was a significant net benefit in the RT+Meat compared with CRT group for overall HR-QoL and the physical component summary (PCS) score (P<0·01), but there were no changes in either group in the mental component summary (MCS) score. Changes in lower limb muscle strength, but not LTM, were positively associated with changes in overall HR-QoL (muscle strength, β: 2·2 (95 % CI 0·1, 4·3), P<0·05). In conclusion, a combination of RT and increased dietary protein led to greater net benefits in overall HR-QoL in elderly women compared with RT alone, which was because of greater improvements in PCS rather than MCS.

To review our institutional outcomes of patients treated with radiation therapy (RT) for Graves' orbitopathy (GO), assess the role of orbital reirradiation, and identify prognostic factors of complete response (CR). This is a retrospective review of 211 patients who presented with a diagnosis of GO and received RT between January 2000-2010. RT dose was 20 Gy in 10 fractions. Patient median age was 51 years (range, 15-84 years), median follow-up was 11 months (range, 1-88 months). Patient symptoms included any combination of proptosis (90.9%), extraocular muscle dysfunction (78.9%), soft tissue signs (68.4%), and diplopia (58.4%). Corticosteroids were used as first-line therapy in 20.6% of patients. Among those who achieved either CR or partial response (PR), prognostic factors were evaluated. Stabilization of disease without recurrence was clinically achieved overall in 202 patients (96.7%). At the completion of RT, 176 patients (84.2%) reported a symptomatic improvement of pretreatment symptoms. CR of GO symptoms was achieved using multiple treatment modalities, including RT by 93 patients (44.5%), of which 32 patients received RT only. Corticosteroids were discontinued in 97.8% of patients who received them as initial therapy. Surgical intervention following radiotherapy was required for 144 (68.9%) of all patients. Fourteen patients received orbital reirradiation for persistent or recurrent symptoms. Five of these achieved a CR, and the other nine achieved disease stabilization but retained persistent ocular symptoms. Long-term side effects of RT included dry eyes (12%). Of the prognostic factors we investigated, only gender predicted CR, which was less common in men (33.9%) than in women (49.7%) p = 0.0471. Orbital radiation for GO is an established treatment modality for patients. Orbital reirradiation is beneficial for patients who do not respond to initial RT or experience symptom recurrence without an apparent risk of increased morbidity. Copyright © 2012 Elsevier Inc.

Castle, Katherine O.; Guadagnolo, B. Ashleigh, E-mail: aguadagn@mdanderson.org; Tsai, C. Jillian

Purpose: To evaluate outcomes of conservative surgery and radiation therapy (RT) treatment in patients with dermatofibrosarcoma protuberans. Methods and Materials: We retrospectively reviewed the medical records of 53 consecutive dermatofibrosarcoma protuberans patients treated with surgery and preoperative or postoperative radiation therapy between 1972 and 2010. Median tumor size was 4 cm (range, 1-25 cm). Seven patients (13%) were treated with preoperative RT (50-50.4 Gy) and 46 patients (87%) with postoperative RT (60-66 Gy). Of the 46 patients receiving postoperative radiation, 3 (7%) had gross disease, 14 (30%) positive margins, 26 (57%) negative margins, and 3 (7%) uncertain margin status. Radiationmore » dose ranged from 50 to 66 Gy (median dose, 60 Gy). Results: At a median follow-up time of 6.5 years (range, 0.5 months-23.5 years), 2 patients (4%) had disease recurrence, and 3 patients (6%) had died. Actuarial overall survival was 98% at both 5 and 10 years. Local control was 98% and 93% at 5 and 10 years, respectively. Disease-free survival was 98% and 93% at 5 and 10 years, respectively. The presence of fibrosarcomatous change was not associated with increased risk of local or distant relapse (P=.43). One of the patients with a local recurrence had gross residual disease at the time of RT and despite RT to 65 Gy developed both an in-field recurrence and a nodal and distant recurrence 3 months after RT. The other patient with local recurrence was found to have in-field recurrence 10 years after initial treatment. Thirteen percent of patients had an RT complication at 5 and 10 years, and 9% had a moderate or severe complication at 5 and 10 years. Conclusions: Dermatofibrosarcoma protuberans is a radioresponsive disease with excellent local control after conservative surgery and radiation therapy. Adjuvant RT should be considered for patients with large or recurrent tumors or when attempts at wide surgical margins would result in significant morbidity.« less

Purpose: Deleterious oral mucositis (OM) develops during radiotherapy (RT) or chemoradiotherapy for head-and-neck cancer (HNC) patients. There are currently no effective cytoprotective treatments for OM without a potential risk of tumor protection. This randomized, double-blind, placebo-controlled pilot study aimed to determine the therapeutic safety and efficacy of phenylbutyrate (an antitumor histone deacetylase inhibitor and chemical chaperone) 5% mouthwash for treating OM caused by cancer therapy. Methods and Materials: Between September 2005 and June 2006, 36 HNC patients were randomized to standard oral care plus 5 mL of either phenylbutyrate 5% mouthwash (n = 17) or placebo (mouthwash vehicle, n =more » 19) taken four times daily (swish and spit). Treatment began when mild mucositis (Radiation Therapy Oncology Group Grade 1) occurred, and ended 4 weeks after RT completion. Safety and efficacy were based on adverse events, physical examination, laboratory determinations, vital signs, Oral Mucosa Assessment Scale (OMAS) and World Health Organization scores, the ability to eat, body weight change, local control, and survival. Results: We found no severe drug-related side effect. At RT doses of 5500-7500 cGy, phenylbutyrate significantly mitigated the severity of mucositis compared with placebo, based on both the WHO score (severity {>=} 3; p = 0.0262) and the OMAS scale (ulceration score {>=} 2; p = 0.0049). The Kaplan-Meier estimates for 2- and 3-year local control, and overall survival were 100% and 80.8%, and 78.6% and 64.3%, respectively, in the phenylbutyrate group and 74.2% and 74.2%, and 57.4% and 50.2%, respectively, in the placebo group. Conclusions: This pilot trial suggested that phenylbutyrate mouthwash significantly decreased the impact of OM in HNC patients receiving RT or chemoradiotherapy and did not confront the tumor control. Larger Phase II randomized trials are needed to confirm these results.« less

Bruheim, Kjersti, E-mail: Kjersti.bruheim@medisin.uio.n; Guren, Marianne G.; Dahl, Alv A.

Purpose: Knowledge of sexual problems after pre- or postoperative radiotherapy (RT) with 50 Gy for rectal cancer is limited. In this study, we aimed to compare self-rated sexual functioning in irradiated (RT+) and nonirradiated (RT-) male patients at least 2 years after surgery for rectal cancer. Methods and Materials: Patients diagnosed with rectal cancer from 1993 to 2003 were identified from the Norwegian Rectal Cancer Registry. Male patients without recurrence at the time of the study. The International Index of Erectile Function, a self-rated instrument, was used to assess sexual functioning, and serum levels of serum testosterone were measured. Results:more » Questionnaires were returned from 241 patients a median of 4.5 years after surgery. The median age was 67 years at survey. RT+ patients (n = 108) had significantly poorer scores for erectile function, orgasmic function, intercourse satisfaction, and overall satisfaction with sex life compared with RT- patients (n = 133). In multiple age-adjusted analysis, the odds ratio for moderate-severe erectile dysfunction in RT+ patients was 7.3 compared with RT- patients (p <0.001). Furthermore, erectile dysfunction of this degree was associated with low serum testosterone (p = 0.01). Conclusion: RT for rectal cancer is associated with significant long-term effects on sexual function in males.« less

Purpose: To critically assess the prognostic value of the European Organization for Research and Treatment of Cancer–Soft Tissue and Bone Sarcoma Group (EORTC-STBSG) response score and define histologic appearance after preoperative radiation therapy (RT) for soft tissue sarcoma (STS). Methods and Materials: For a cohort of 100 patients with STS of the extremity/trunk treated at our institution with preoperative RT followed by resection, 2 expert sarcoma pathologists evaluated the resected specimens for percent residual viable cells, necrosis, hyalinization/fibrosis, and infarction. The EORTC response score and other predictors of recurrence-free survival (RFS) and overall survival (OS) were assessed by Kaplan-Meier and proportionalmore » hazard models. Results: Median tumor size was 7.5 cm; 92% were intermediate or high grade. Most common histologies were unclassified sarcoma (34%) and myxofibrosarcoma (25%). Median follow-up was 60 months. The 5-year local recurrence rate was 5%, 5-year RFS was 68%, and 5-year OS was 75%. Distribution of cases according to EORTC response score tiers was as follows: no residual viable tumor for 9 cases (9% pathologic complete response); <1% viable tumor for 0, ≥1% to <10% for 9, ≥10% to <50% for 44, and ≥50% for 38. There was no association between EORTC-STBSG response score and RFS or OS. Conversely, hyalinization/fibrosis was a significant independent favorable predictor for RFS (hazard ratio 0.49, P=.007) and OS (hazard ratio 0.36, P=.02). Conclusion: Histologic evaluation after preoperative RT for STS showed a 9% pathologic complete response rate. The EORTC-STBSG response score and percent viable cells were not prognostic.

In a previous study, we found that Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) overpredicts morbidity risk in emergency gastrointestinal surgery. Our aim was to find a POSSUM equation adjustment. A prospective observational study was performed on 2,361 patients presenting with a community-acquired gastrointestinal surgical emergency. The first 1,000 surgeries constituted the development cohort, the second 1,000 events were the first validation intramural cohort, and the remaining 361 cases belonged to a second validation extramural cohort. (1) A modified POSSUM equation was obtained. (2) Logistic regression was used to yield a statistically significant equation that included age, hemoglobin, white cell count, sodium and operative severity. (3) A chi-square automatic interaction detector decision tree analysis yielded a statistically significant equation with 4 variables, namely cardiac failure, sodium, operative severity, and peritoneal soiling. A modified POSSUM equation and a simplified scoring system (aLicante sUrgical Community Emergencies New Tool for the enUmeration of Morbidities [LUCENTUM]) are described. Both tools significantly improve prediction of surgical morbidity in community-acquired gastrointestinal surgical emergencies. Copyright © 2016 Elsevier Inc. All rights reserved.

Use of different subjective health indicators to assess health inequalities in an urban immigrant population in north-western Italy: a cross-sectional study

PubMed Central

2013-01-01

Background Despite the steady growth of the immigrant population in Italy, data on the health status of immigrants are scarce. Our main goals were to measure Health-Related Quality of Life (HRQoL), Self-Rated Health (SRH) and morbidity among immigrants in Genoa. We aimed to assess the relative contribution of some social, structural and behavioral determinants to “within-group” health disparities. Methods We enrolled 502 subjects by means of snowball sampling. The SF-12 questionnaire, integrated with socio-demographic and health-related items, was used. Multivariate logistic and Poisson regression models were applied in order to identify characteristics associated with poor SRH, lower SF-12 scores and prevalence of self-reported morbidities. Results Subjects showed relatively moderate levels of HRQoL (median physical and mental scores of 51.6 and 47.3, respectively) and about 15% of them rated their health as fair or poor. Lower scores in the physical dimension of HRQoL were associated with the presence of morbidities and immigration for work and religious reasons, while those who had migrated for religious and family reasons displayed a lower probability of lower scores in the mental dimension of HRQoL. Poor SRH was associated with female gender, overweight/obesity and presence of morbidities. Moreover, compared with immigrants from countries with a low human development index, immigrants from highly developed societies showed significantly lower odds of reporting poor SRH. About one-third of respondents reported at least one medical condition, while the prevalence of multi-morbidity was 10%. Females, over 45-year-olds, overweight and long-term immigrants had a higher prevalence of medical conditions. Conclusions Our study confirms the presence of health inequalities within a heterogeneous immigrant population. HRQoL, SRH and morbidity are valid, relatively rapid and cheap tools for measuring health inequalities, though they do so in different ways. These indicators should be used with caution and, if possible, simultaneously, as they could help to identify and to monitor more vulnerable subjects among immigrants. PMID:24156544

To our knowledge, no study has specifically assessed the time course of anxiety during radiotherapy (RT). The objective of this study was to assess anxiety time courses in patients with non-metastatic breast cancer. This multicenter, descriptive longitudinal study included 213 consecutive patients with breast cancer who completed visual analog scales (VASs) assessing state anxiety before and after the RT simulation and the first and last five RT sessions. Pre- and post-session anxiety mean levels were highest at the RT simulation (respectively, 2.9±2.9 and 1.6±2.5) and first RT session (respectively, 3.4±2.9 and 2.0±2.4), then declined rapidly. Clinically relevant mean differences (⩾1cm on the VAS) between pre- and post-simulation/session VAS scores were found only for the RT simulation (-1.3±2.7; p<0.001) and first RT session (-1.4±2.4; p<0.001). Five percent to 16% of patients presented clinically relevant anxiety (pre- and post-simulation/session VAS scores⩾4cm) throughout treatment. To optimize care, RT team members should offer all patients appropriate information about treatment at the simulation, check patients' understanding, and identify patients with clinically relevant anxiety requiring appropriate support throughout RT.

In Spain, nearly 14% of the population is diabetic, 95% corresponds to Type 2 Diabetes Mellitus patients. Poor glycemic control increases morbidity and mortality. There are three pillars in the treatment of type 2 diabetes: diet, medication and exercise. However, the potential for prescribing exercise training has not been fully exploited. To analyze the effect of different exercise modalities (AE, RT, Combo, HIIT) on glycemic control in patients with type 2 diabetes mellitus. The reserch was performed in 3 electronic databases (Pubmed, Scopus and Proquest), including publications from 2011 to the present, publications undertaking interventions with AE, RT, Combo or HIIT, and those that measured capillary glucose, CGMS or HbA1c. Of the 386 articles found, 14 met the inclusion criteria. These items were classified according to exercise intervention modality (AE, RT, Combo, HIIT) and whether glycemic control was measured as a result of continued training or 24-48h post-workout. EA, RT, Combo and HIIT show efficacy in glycemic control in both the continuous training and 24-48h post-training. To achieve certain benefits in glycemic control, prescribing a structured frequency, volume and intensity training is required. Combo is the modality that gets better results through continued training. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

The role of test-retest reliability in measuring individual and group differences in executive functioning.

PubMed

Paap, Kenneth R; Sawi, Oliver

2016-12-01

Studies testing for individual or group differences in executive functioning can be compromised by unknown test-retest reliability. Test-retest reliabilities across an interval of about one week were obtained from performance in the antisaccade, flanker, Simon, and color-shape switching tasks. There is a general trade-off between the greater reliability of single mean RT measures, and the greater process purity of measures based on contrasts between mean RTs in two conditions. The individual differences in RT model recently developed by Miller and Ulrich was used to evaluate the trade-off. Test-retest reliability was statistically significant for 11 of the 12 measures, but was of moderate size, at best, for the difference scores. The test-retest reliabilities for the Simon and flanker interference scores were lower than those for switching costs. Standard practice evaluates the reliability of executive-functioning measures using split-half methods based on data obtained in a single day. Our test-retest measures of reliability are lower, especially for difference scores. These reliability measures must also take into account possible day effects that classical test theory assumes do not occur. Measures based on single mean RTs tend to have acceptable levels of reliability and convergent validity, but are "impure" measures of specific executive functions. The individual differences in RT model shows that the impurity problem is worse than typically assumed. However, the "purer" measures based on difference scores have low convergent validity that is partly caused by deficiencies in test-retest reliability. Copyright © 2016 Elsevier B.V.

Background To characterize the surface topography of several dental implants for commercial use. Material and Methods Dental implants analyzed were Certain (Biomet 3i), Tissue Level (Straumann), Interna (BTI), MG-InHex (MozoGrau), SPI (Alphabio) and Hikelt (Bioner). Surface topography was ascertained using a confocal microscope with white light. Roughness parameters obtained were: Ra, Rq, Rv, Rp, Rt, Rsk and Rku. The results were analysed using single-factor ANOVA and Student-Neuman-Keuls(p<0.05) tests. Results Certain and Hikelt obtained the highest Ra and Rq scores, followed by Tissue Level. Interna and SPI obtained lower scores, and MG-InHex obtained the lowest score. Rv scores followed the same trend. Certain obtained the highest Rp score, followed by SPI and Hikelt, then Interna and Tissue Level. MG-InHex obtained the lowest scores. Certain obtained the highest Rt score, followed by Interna and Hikelt, then SPI and Tissue Level. The lowest scores were for MG-InHex. Rsk was negative (punctured surface) in the MG-InHex, SPI and Tissue Level systems, and positive (pointed surface) in the other systems. Rku was higher than 3 (Leptokurtic) in Tissue Level, Interna, MG-InHex and SPI, and lower than 3 (Platykurtic) in Certain and Hikelt. Conclusions The type of implant determines surface topography, and there are differences in the roughness parameters of the various makes of implants for clinical use. Key words:Implants for clinical use, topography, confocal microscopy. PMID:27475680

After birth, a newborn calf has to adapt to an extrauterine life characterized by several physiological changes. In particular, maturation of the gastrointestinal tract in a new environment loaded with potential pathogens, which can predispose neonatal calves to develop diarrhea, and is a major cause of morbidity and mortality during the first 4 wks of life. We aimed to investigate the inflammatory adaptations at a transcriptomic level in the gastrointestinal (GI) tract to a mild diarrhea in neonatal dairy calves using RNA isolated from fresh fecal samples. Eight newborn Jersey male calves were used from birth to 5 wks of age and housed in individual pens. After birth, calves received 1.9 L of colostrum from their respective dams. Calves had ad-libitum access to water and starter grain (22% CP) and were fed twice daily a total of 5.6 L pasteurized whole milk. Starter intake, body weight (BW), fecal score, withers height (WH), and rectal temperature (RT) were recorded throughout the experiment. Blood samples were collected weekly for metabolic and inflammatory profiling from wk 0 to wk 5. Fresh fecal samples were collected weekly and immediately flash frozen until RNA was extracted using a Trizol-based method, and subsequently, an RT-qPCR analysis was performed. Orthogonal contrasts were used to evaluate linear or quadratic effects over time. Starter intake, BW, and WH increased over time. Fecal score was greatest (2.6 ± 0.3) during wk 2. The concentrations of IL-6, ceruloplasmin, and haptoglobin had a positive quadratic effect with maximal concentrations during wk 2, which corresponded to the maximal fecal score observed during the same time. The concentration of serum amyloid A decreased over time. The mRNA expression of the proinflammatory related genes TLR4, TNFA, IL8, and IL1B had a positive quadratic effect of time. A time effect was observed for the cell membrane sodium-dependent glucose transporter SLC5A1, for the major carbohydrate facilitated transporter SLC2A2, and water transport function AQP3, where SLC5A1 and AQP3 had a negative quadratic effect over time. Our data support the use of the fecal RNA as a noninvasive tool to investigate intestinal transcriptomic profiling of dairy calves experiencing diarrhea, which would be advantageous for future research including nutritional effects and health conditions.

D'Amico, Anthony V.; Chen, M.-H.; Renshaw, Andrew A.

Purpose: To assess whether the risk of death is associated with the time to testosterone recovery (TTR) after radiotherapy (RT) and hormonal therapy (HT) for prostate cancer (PCa). Patients and Methods: Between 1995 and 2001, 206 men with localized, unfavorable-risk PCa were randomized to receive RT or RT plus 6 months of HT. A multivariate postrandomization Cox regression analysis was used to assess whether the TTR in years was associated with the risk of death after adjusting for the known prognostic factors, age, Adult Comorbidity Evaluation-27 score, and the use of HT for recurrence. Results: Of the 102 men randomizedmore » to receive RT and HT, 57 (56%) had a TTR of >2 years, and none of these men had died of PCa after a median follow-up of 7.6 years. As the TTR increased, the risk of death decreased significantly (adjusted hazard ratio, 0.60; 95% confidence interval, 0.43-0.84; p = .003). A significant interaction was noted between the TTR and the comorbidity score (p = .002). The survival estimates were similar (p = 0.17) across the TTR values in men with moderate to severe comorbidity; however, these estimates increased significantly (p < .001) with decreasing PCa-specific mortality (p = .006) as the TTR increased in men with no or minimal comorbidity. Conclusion: The results of our study have shown that a longer TTR after RT plus 6 months of HT for unfavorable-risk PCa is associated with a lower risk of death in men with no or minimal comorbidity.« less

Recommendations for prevention of cardiovascular diseases (CVDs) risk factors among older adults highlighted the importance of exercise-based interventions, including endurance training (ET). However, the evidence of efficacy of other interventions based on short-bouts of exercise (circuit training, CT), and the practice of breath-control and meditation (relaxing training, RT) is growing. The aim of this study was to elucidate if CT or RT are equally effective in CVD risk factors reduction compared to ET. To this purpose, in 40 elderly participants, with clinically diagnosed grade 1 hypertension, resting blood pressure, blood glucose, and cholesterol levels, peak oxygen uptake ([Formula: see text]), mechanical efficiency and quality of life were evaluated before and after 12 weeks of ET, CT, and RT treatments. Resting blood pressure reduced significantly in all groups by ∼11 %. In ET, blood cholesterol levels (-18 %), [Formula: see text] (+8 %), mechanical efficiency (+9 %), and quality of life scores (+36 %) ameliorated. In CT blood glucose levels (-11 %), [Formula: see text] (+7 %) and quality of life scores (+35 %) were bettered. Conversely, in RT, the lower blood pressure went along only with an improvement in the mental component of quality of life (+42 %). ET and CT were both appropriate interventions to reduce CVDs risk factors, because blood pressure reduction was accompanied by decreases in blood glucose and cholesterol levels, increases in [Formula: see text], mechanical efficiency, and quality of life. Although RT influenced only blood pressure and quality of life, this approach would be an attractive alternative for old individuals unable or reluctant to carry out ET or CT.

Purpose: The purpose of this study was to compare chemoradiation therapy (CRT) with radiation therapy (RT) only in an older patient population with head and neck squamous cell carcinoma (HNSCC). Methods and Materials: Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database (1992-2007), we identified a retrospective cohort of nonmetastatic HNSCC patients and divided them into treatment groups. Comparisons were made between CRT and RT cohorts. Propensity scores for CRT were estimated from covariates associated with receipt of treatment using multivariable logistic regression. Standardized mortality ratio weights (SMRW) were created from the propensity scores and used to balance groupsmore » on measured confounders. Multivariable and SMR-weighted Cox proportional hazard models were used to estimate the hazard ratio (HR) of death for receipt of CRT versus RT among the whole group and for separate patient and tumor categories. Results: The final cohort of 10,599 patients was 68% male and 89% white. Median age was 74 years. Seventy-four percent were treated with RT, 26% were treated with CRT. Median follow-up points for CRT and RT survivors were 4.6 and 6.3 years, respectively. On multivariable analysis, HR for death with CRT was 1.13 (95% confidence interval [CI]: 1.07-1.20; P<.01). Using the SMRW model, the HR for death with CRT was 1.08 (95% CI: 1.02-1.15; P=.01). Conclusions: Although the addition of chemotherapy to radiation has proven efficacious in many randomized controlled trials, it may be less effective in an older patient population treated outside of a controlled trial setting.« less

To demonstrate the feasibility of Real-time magnetic resonance imaging (rtMRI) guided transcatheter aortic valve replacement (TAVR) with an active guidewire and an MRI compatible valve delivery catheter system in a swine model. The CoreValve system was minimally modified to be MRI-compatible by replacing the stainless steel components with fluoroplastic resin and high-density polyethylene components. Eight swine weighing 60-90 kg underwent rtMRI-guided TAVR with an active guidewire through a left subclavian approach. Two imaging planes (long-axis view and short-axis view) were used simultaneously for real-time imaging during implantation. Successful deployment was performed without rapid ventricular pacing or cardiopulmonary bypass. Postdeployment images were acquired to evaluate the final valve position in addition to valvular and cardiac function. Our results show that the CoreValve can be easily and effectively deployed through a left subclavian approach using rtMRI guidance, a minimally modified valve delivery catheter system, and an active guidewire. This method allows superior visualization before deployment, thereby allowing placement of the valve with pinpoint accuracy. rtMRI has the added benefit of the ability to perform immediate postprocedural functional assessment, while eliminating the morbidity associated with radiation exposure, rapid ventricular pacing, contrast media renal toxicity, and a more invasive procedure. Use of a commercially available device brings this rtMRI-guided approach closer to clinical reality. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc.

Quality of life has become a major issue in determining the outcome of treatment in head and neck surgery with curative intent. The aim of our study was to determine which factors in the postoperative care, especially shoulder and neck morbidity, are related to quality of life and how these outcomes compared between patients who had undergone surgery and a control group. We analyzed physical symptoms, psychological symptoms, and social and functional well-being at least 1 year after surgery and evaluated the differences in quality of life between patients who had undergone head and neck surgery and a control group. Depression scores contributed significantly to all domains of quality of life. Reduced shoulder abduction, shoulder pain, and neck pain are related to several domains of quality of life. The patient group scored significantly worse for social functioning and limitations from physical problems but scored significantly better for bodily pain and health changes. Depression and shoulder and neck morbidity are important factors in quality of life for patients who have undergone surgery for head and neck cancer. (c) 2004 Wiley Periodicals, Inc.

To estimate the morbidity, mortality, and lifetime costs of care for rheumatoid arthritis (RA). We developed a Markov model based on the Arthritis, Rheumatism, and Aging Medical Information System Post-Marketing Surveillance Program cohort, involving 4,258 consecutively enrolled RA patients who were followed up for 17,085 patient-years. Markov states of health were based on drug treatment and Health Assessment Questionnaire scores. Costs were based on resource utilization, and utilities were based on visual analog scale-based general health scores. The cohort had a mean age of 57 years, 76.4% were women, and the mean duration of disease was 11.8 years. Compared with a life expectancy of 22.0 years for the general population, this cohort had a life expectancy of 18.6 years and 11.3 quality-adjusted life years. Lifetime direct medical care costs were estimated to be $93,296. Higher costs were associated with higher disability scores. A Markov model can be used to estimate lifelong morbidity, mortality, and costs associated with RA, providing a context in which to consider the potential value of new therapies for the disease.

Rasch-Transformed Total Neuropathy Score clinical version (RT-TNSc(©) ) in patients with chemotherapy-induced peripheral neuropathy.

2015-09-01

Composite scales such as the Total Neuropathy Score clinical version (TNSc(©) ) have been widely used to measure neurological impairment in a standardized manner but they have been criticized due to their ordinal setting having no fixed unit. This study aims to improve impairment assessment in patients with chemotherapy-induced peripheral neuropathy (CIPN) by subjecting TNSc(©) records to Rasch analyses. In particular, we wanted to investigate the influence of factors affecting the use of the TNSc(©) in clinical practice. TNSc(©) has 7 domains (sensory, motor, autonomic, pin-prick, vibration, strength, and deep tendon reflexes [DTR]) each being scored 0-4. Data obtained in 281 patients with stable CIPN were subjected to Rasch analyses to determine the fit to the model. The TNSc(©) did not meet Rasch model's expectations primarily because of misfit statistics in autonomic and DTR domains. Removing these two, acceptable model fit and uni-dimensionality were obtained. However, disordered thresholds (vibration and strength) and item bias (mainly cultural) were still seen, but these findings were kept to balance the assessment range of the Rasch-Transformed TNSc(©) (RT-TNSc(©) ). Acceptable reliability findings were also obtained. A 5-domains RT-TNSc(©) may be a more proper assessment tool in patients with CIPN. Future studies are needed to examine its responsive properties. © 2015 Peripheral Nerve Society.

This study aims to identify the clinical implications of myocardial perfusion defects after chemoradiation therapy (CRT) in patients with esophageal and lung cancer. We retrospectively compared myocardial perfusion imaging (MPI) results before and after CRT in 16 patients with esophageal cancer and 24 patients with lung cancer. New MPI defects in the radiation therapy (RT) fields were considered related to RT. Follow-up to evaluate for cardiac complications and their relation with the results of MPI was performed. Statistical analysis identified predictors of cardiac morbidities. Eleven females and twenty nine males at a mean age of 66.7 years were included. Five patients (31%) with esophageal cancer and seven patients (29%) with lung cancer developed myocardial ischemia in the RT field at mean intervals of 7.0 and 8.4 months after RT. The patients were followed-up for mean intervals of 15 and 23 months in the esophageal and lung cancer groups, respectively. Seven patients in each of the esophageal (44%) and lung (29%) cancer patients (P = 0.5) developed cardiac complications of which one patient with esophageal cancer died of complete heart block. Six out of the fourteen patients (43%) with cardiac complication had new ischemia on MPI after CRT of which only one developed angina. The remaining eight patients with cardiac complications had normal MPI results. MPI result was not a statistically significant predictor of future cardiac complications after CRT. A history of congestive heart failure (CHF) (P = 0.003) or arrhythmia (P = 0.003) is a significant predictor of cardiac morbidity after CRT in univariate analysis but marginal predictors when multivariate analysis was performed (P = 0.06 and 0.06 for CHF and arrhythmia, respectively). Cardiac complications after CRT are more common in esophageal than lung cancer patients but the difference is not statistically significant. MPI abnormalities are frequently seen after CRT but are not predictive of future cardiac complications. A history of arrhythmia or CHF is significantly associated with cardiac complications after CRT.

Purpose: Neoadjuvant chemoradiation (CRT) is increasingly used in locally advanced esophageal cancer. Some studies have suggested that CRT results in increased surgical morbidity. We assessed the influence of CRT on anastomotic complications in a cohort of patients who underwent CRT followed by Ivor Lewis esophagectomy. Patients and Methods: Clinical and pathologic data were collected from all patients treated with neoadjuvant CRT (36 Gy combined with 5-fluorouracil and cisplatin) followed by Ivor Lewis esophagectomy. On the radiotherapy (RT) planning computed tomography scans, normal tissue volumes were drawn encompassing the proximal esophageal region and the gastric fundus. Within these volumes, dose-volume histogramsmore » were analyzed to generate the total dose to 50% of the volume (D{sub 50}). We studied the ability of the D{sub 50} to predict anastomotic complications (leakage, ischemia, or stenosis). Dose limits were derived using receiver operating characteristics analysis. Results: Fifty-four patients were available for analysis. RT resulted in either T or N downstaging in 51% of patients; complete pathologic response was achieved in 11%. In-hospital mortality was 5.4%, and major morbidity occurred in 36% of patients. Anastomotic complications (AC) developed in 7 patients (13%). No significant influence of the D{sub 50} on the proximal esophagus was noted on the anastomotic complication rate. The median D{sub 50} on the gastric fundus, however, was 33 Gy in patients with AC and 18 Gy in patients without AC (p = 0.024). Using receiver operating characteristics analysis, the D{sub 50} limit on the gastric fundus was defined as 29 Gy. Conclusions: In patients undergoing neoadjuvant CRT followed by Ivor Lewis esophagectomy, the incidence of AC is related to the RT dose on the gastric fundus but not to the dose received by the proximal esophagus. When planning preoperative RT, efforts should be made to limit the median dose on the gastric fundus to 29 Gy with a V{sub 30} below 40%.« less

The purpose of this study was to investigate the patterns of delivery of palliative RT across the United States. Using the Surveillance, Epidemiology, and End Results-Medicare linked database, 51,610 patients were identified with incident stage IV breast, prostate, lung, or colorectal cancer diagnosed between 2000 and 2007 and observed through 2009. Multivariate logistic regression determined predictors of palliative RT. Forty-one percent of the study population received palliative RT, including 53% of patients with lung cancer, followed by those with breast (42%), prostate (40%), and colorectal cancers (12%). Multivariate analysis revealed that older patients (P<.001) and those with higher Charlson comorbidity scores (P<.001) were less likely to receive palliative RT. Black patients with prostate cancer were 20% less likely (P<.001), and black patients with colorectal cancer were 28% less likely (P<.001), than white patients to receive palliative RT. Among those treated with RT, 23% of patients with lung cancer died within 2 weeks of completing treatment, followed by those with colorectal (12%), breast (11%), and prostate cancers (8%). In addition to tumor site, significant predictors (P<.05) of death within 2 weeks of receiving RT included increased age, increased comorbidity, and male sex. Inequality in the receipt of palliative RT exists among the elderly and patients with comorbid conditions and varies with race. In addition, a significant number of patients die shortly after receiving RT. Understanding these patterns of care, along with further research into the underlying causes, will improve access and quality of palliative RT.

It is generally agreed upon that the mechanisms underlying task switching heavily depend on working memory, yet numerous studies have failed to show a strong relationship between working memory capacity (WMC) and task-switching ability. We argue that this relationship does indeed exist but that the dependent variable used to measure task switching is problematic. To support our claim, we reanalyzed data from two studies with a new scoring procedure that combines reaction time (RT) and accuracy into a single score. The reanalysis revealed a strong relationship between task switching and WMC that was not present when RT-based switch costs were used as the dependent variable. We discuss the theoretical implications of this finding along with the potential uses and limitations of the scoring procedure we used. More broadly, we emphasize the importance of using measures that incorporate speed and accuracy in other areas of research, particularly in comparisons of subjects differing in cognitive and developmental levels. © The Author(s) 2015.

The comprehensive Aristotle score has been proposed as an individualized measure of the complexity of a given surgical procedure and has been reported to significantly correlate with postoperative morbidity and mortality after the Norwood procedure. An important factor leading to postoperative morbidity and mortality is low cardiac output. We studied the correlation between the comprehensive Aristotle score and cardiac output (CO) in infants after the Norwood procedure. Respiratory mass spectrometry was used to continuously measure systemic oxygen consumption (VO(2)) in 22 infants for 72 hours postoperatively. Arterial, superior vena caval and pulmonary venous blood gases were measured at 2 to 4 hour intervals to calculate CO. The comprehensive Aristotle score was collected. Hospital mortality was 4.5%. The comprehensive Aristotle score ranged from 14.5 to 23.5 and negatively correlated with CO (P = 0.027). Among the patient-adjusted factors, myocardial dysfunction (n = 10), mechanical ventilation to treat cardiorespiratory failure (n = 9) and atrioventricular valve regurgitation (n = 4) (P = 0.01) negatively correlated with CO (P = 0.06 to 0.07). Aortic atresia (n = 9) was associated with a lower CO (P = 0.01) for the first 24 hours which linearly increased overtime (P = 0.0001). No correlation was found between CO and other factors (P > 0.3 for all). Comprehensive Aristotle score significantly negatively correlates with CO after the Norwood procedure. A preoperative estimation of the comprehensive Aristotle score, particularly in association with myocardial dysfunction, mechanical ventilation to treat cardiorespiratory failure, atrioventricular valve regurgitation and aortic atresia may help to anticipate a high postoperative morbidity with low cardiac output syndrome.

The evolution of pharmacologic therapies and mechanical support including ventricular assist devices (VADs) has broadened the scope of care available to children with advanced heart failure. At the present time, there are only limited means of quantifying disease severity or the concomitant morbidity for this population. This study describes the development of a novel pediatric treatment intensity score (TIS), designed to quantify the burden of illness and clinical trajectory in children on VAD support. There were 5 clinical domains assessed: nutrition, respiratory support, activity level, cardiovascular medications, and care environment. A scale was developed through expert consensus. Higher scores indicate greater morbidity as reflected by intensity of medical management. To evaluate feasibility and face validity, the TIS was applied retrospectively to a subset of pediatric inpatients with VADs. The Bland-Altman method was used to assess limits of agreement. The study comprised 39 patients with 42 implantations. Bland-Altman interobserver and intraobserver comparisons showed good agreement (mean differences in scores of 0.02, limits of agreement ±0.12). Trends in TIS were concordant with the overall clinical impression of improvement. Scores remained ≥0.6 preceding VAD implantation and peaked at 0.71 3 days after VAD implantation. We describe a pediatric VAD scoring tool, to assess global patient morbidity and clinical recovery. We demonstrate feasibility of using this TIS in a test population of inpatients on VAD support.

Susceptibility to motion sickness (MS) is known to be affected by gender and ethnic origin, but whether gender and ethnicity are interacting is unknown. We investigated MS development in healthy Caucasian subjects (n = 227), and in subjects of Chinese origin (n = 82). All subjects were exposed to nausea-inducing body rotations in a rotation chair, and rotated around the yaw axis for 5 x 1 min, while they were instructed to move their heads. Prior to rotation, subjects had to fill out a motion-sickness susceptibility questionnaire (MSSQ). Total rotation tolerance time (RT) was noted. Symptom ratings (SR) were performed at the beginning, and immediately after the end of each rotation, and 15 and 30 min later. The average RT was significantly higher in Caucasian (163 +/- 6 s) than in Chinese subjects (111 +/- 7 s) (F = 24.84, p < 0.0001). The adult MSSQ score was significantly lower in Caucasians (17.8 +/- 1.1) than in Chinese volunteers (24.2 +/- 2.1) (F = 6.05, p = 0.014). Maximal SR post rotation was similar in Chinese and Caucasian subjects. RT was highly predictable from the MSSQ scores, but separate for both genders. Susceptibility to MS is affected by both ethnic origin and by gender in a rather complex fashion. The most reliable prediction of RT can be based on the individual's history as assessed by the MSSQ.

The objective was to compare patients after matrix-associated autologous chondrocyte transplantation (MACT) and microfracture therapy (MFX) of the talus using diffusion-weighted imaging (DWI), with morphological and clinical scoring. Twenty patients treated with MACT or MFX (10 per group) were examined using 3 T magnetic resonance imaging (MRI) at 48 ± 21.5 and 59.6 ± 23 months after surgery, respectively. For comparability, patients from each group were matched by age, body mass index, and follow-up. American Orthopaedic Foot and Ankle Society (AOFAS) score served as clinical assessment tool pre- and postoperatively. DWI was obtained using a partially balanced, steady-state gradient echo pulse sequence, as well as the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score, based on a 2D proton density-weighted turbo spin-echo sequence and a 3D isotropic true fast imaging with steady-state precession sequence. Semi-quantitative diffusion quotients were calculated after region of interest analysis of repair tissue (RT) and healthy control cartilage, and compared among both groups. The mean AOFAS score improved significantly (P = 0.001) for both groups (MACT: 48.8 ± 20.4-83.6 ± 9.7; MFX: 44.3 ± 16.5-77.6 ± 13.2). No differences in the AOFAS (P = 0.327) and MOCART (P = 0.720) score were observed between MACT and MFX postoperatively. DWI distinguished between healthy cartilage and cartilage RT in the MFX group (P = 0.016), but not after MACT treatment (P = 0.105). Significant correlations were found between MOCART score and DWI index after MFX (Pearson: -0.648; P = 0.043), and between the diffusivity and longer follow-up interval in MACT group (Pearson: -0.647, P = 0.043). Whereas conventional scores reveal a similar outcome after MACT or MFX treatment in the ankle joint, DWI was able to distinguish between different RT qualities, as reported histologically for these diverse surgical procedures.

Purpose: Cardiac toxicity after breast radiotherapy (RT) has been widely described in 'older' RT trials (i.e., using larger fraction sizes, wide RT fields, and orthovoltage energy). The results from more 'modern' RT trials have shown less cardiac toxicity. The comparisons between the 'older' and 'modern' trials are confounded by the longer follow-up time in the 'older' trials. We systematically assessed the effect of treatment era and follow-up duration on the reported rates of cardiac toxicity associated with RT. Methods and Materials: The published data were surveyed using PubMed to identify studies using 'breast cancer,' 'irradiation/radiotherapy,' 'cardiac/heart,' and 'toxicity/morbidity/mortality' in amore » keyword search. Relevant data were extracted from the identified trials. The trials were defined as 'older' (patient accrual start year before 1980) and 'modern' (patient accrual start year in or after 1980) to segregate the trials and assess the treatment era effect. A 10-year follow-up duration was used as a cutoff to segregate and analyze trials with varying lengths of follow-up. Results: We analyzed 19 published reports of patients treated between 1968 and 2002 (5 randomized controlled trials, 5 single- or multi-institutional studies, and 9 national cancer registry database reviews). In the reviewed trials, all the older trials reported excess cardiac toxicity, typically with a median of >10-15 years of follow-up. However, the vast majority of modern RT trials had shorter median follow-up durations, typically {<=}10 years and did not report an excess toxicity risk. The modern studies lacked longer follow-up. Conclusion: Additional follow-up is needed to ensure that modern methods effectively reduce cardiac toxicity. Continued diligence to minimize cardiac exposure remains prudent.« less

To evaluate the toxicity and efficacy of accelerated hyperfractionated radiotherapy (RT) for locally advanced cervical cancer. A multi-institutional prospective single-arm study was conducted among eight Asian countries. Between 1999 and 2002, 120 patients (64 with Stage IIB and 56 with Stage IIIB) with squamous cell carcinoma of the cervix were treated with accelerated hyperfractionated RT. External beam RT consisted of 30 Gy to the whole pelvis, 1.5 Gy/fraction twice daily, followed by 20 Gy of pelvic RT with central shielding at a dose of 2-Gy fractions daily. A small bowel displacement device was used with the patient in the prone position. In addition to central shielding RT, intracavitary brachytherapy was started. Acute and late morbidities were graded according to the Radiation Therapy Oncology Group and Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. The median overall treatment time was 35 days. The median follow-up time for surviving patients was 4.7 years. The 5-year pelvic control and overall survival rate for all patients was 84% and 70%, respectively. The 5-year pelvic control and overall survival rate was 78% and 69% for tumors > or = 6 cm in diameter, respectively. No treatment-related death occurred. Grade 3-4 late toxicities of the small intestine, large intestine, and bladder were observed in 1, 1, and 2 patients, respectively. The 5-year actuarial rate of Grade 3-4 late toxicity at any site was 5%. The results of our study have shown that accelerated hyperfractionated RT achieved sufficient pelvic control and survival without increasing severe toxicity. This treatment could be feasible in those Asian countries where chemoradiotherapy is not available.

Cardiac morbidity is an important late effect in long-term childhood cancer survivors (CCS) treated with cardiotoxic agents or radiotherapy (RT) on the chest. However, there is limited data on the long-term cardiac sequelae in CCS who only received cranial RT. We hypothesized that cranial RT might negatively influence cardiac structure and function. We studied 13 CCS [mean age 30.8 (18.1-39.3) years, 7 males] who received RT only on the head for a cranial tumor and 36 age- and sex-matched healthy sibling controls. Echocardiographic follow-up was performed at median 21.7 (12.6-30.8) years after diagnosis. CCS had lower indexed diastolic LV volumes [56.0 (31.4-68.3) vs. 60.5 (41.9-94.3) mL/m(2), p = 0.024]. CCS also had reduced LV systolic and diastolic function, reflected by lower systolic LV myocardial velocities (5.3 ± 0.9 vs. 7.1 ± 1.7 cm/s, p = 0.001) and longitudinal deformation (- 17.3 ± 3.1 vs. - 20.7 ± 2.0%, p < 0.001), as well as lower diastolic LV myocardial velocities (- 10.7 ± 1.7 vs. - 12.2 ± 1.5 cm/s, p = 0.006) and deformation speed (1.1 ± 0.3 vs. 1.5 ± 0.2 1/s, p = 0.005). Additionally, in CCS insulin-like growth factor levels [15.4 (9.2-34.6) vs. 24.4 (14.8-55.5) nmol/L, p = 0.007] were lower. Cranial RT in CCS is associated with smaller cardiac volumes and reduced systolic and diastolic LV function. This off target effect of RT might be related to lower insulin-like growth factor levels.

Valle, Luca F.; Jagsi, Reshma; Bobiak, Sarah N.

Purpose: This study determined practice patterns in the staging and treatment of patients with stage I non-small cell lung cancer (NSCLC) among National Comprehensive Cancer Network (NCCN) member institutions. Secondary aims were to determine trends in the use of definitive therapy, predictors of treatment type, and acute adverse events associated with primary modalities of treatment. Methods and Materials: Data from the National Comprehensive Cancer Network Oncology Outcomes Database from 2007 to 2011 for US patients with stage I NSCLC were used. Main outcome measures included patterns of care, predictors of treatment, acute morbidity, and acute mortality. Results: Seventy-nine percent ofmore » patients received surgery, 16% received definitive radiation therapy (RT), and 3% were not treated. Seventy-four percent of the RT patients received stereotactic body RT (SBRT), and the remainder received nonstereotactic RT (NSRT). Among participating NCCN member institutions, the number of surgeries-to-RT course ratios varied between 1.6 and 34.7 (P<.01), and the SBRT-to-NSRT ratio varied between 0 and 13 (P=.01). Significant variations were also observed in staging practices, with brain imaging 0.33 (0.25-0.43) times as likely and mediastinoscopy 31.26 (21.84-44.76) times more likely for surgical patients than for RT patients. Toxicity rates for surgical and for SBRT patients were similar, although the rates were double for NSRT patients. Conclusions: The variations in treatment observed among NCCN institutions reflects the lack of level I evidence directing the use of surgery or SBRT for stage I NSCLC. In this setting, research of patient and physician preferences may help to guide future decision making.« less

The aim of this study is to examine the prevalence and correlates of adolescents' resistance training (RT) skill competence. Participants were 548 adolescents (14.1 ± 0.5 years) from 16 schools in New South Wales, Australia. RT skills were assessed using the Resistance Training Skills Battery. Demographics, BMI, muscular fitness, perceived strength, RT self-efficacy, and motivation for RT were also assessed. The proportion demonstrating "competence" and "near competence" in each of the six RT skills were calculated and sex differences explored. Associations between the combined RT skill score and potential correlates were examined using multi-level linear mixed models. Overall, the prevalence of competence was low (range = 3.3% to 27.9%). Females outperformed males on the squat, lunge and overhead press, whereas males performed better on the push-up (p < .05). Significant associations were seen for a number of correlates, which largely differed by sex. Muscular fitness was moderately and positively associated with RT skills among both males (β = 0.34, 95%CIs = 0.23 to 0.46) and females (β = 0.36, 95%CIs = 0.23 to 0.48). Our findings support a link between RT skills and muscular fitness. Other associations were statistically significant but small in magnitude, and should therefore be interpreted cautiously.

The optimum mode of breech delivery remains a matter of controversy among obstetricians worldwide. To determine whether term breech babies born by planned vaginal delivery are at higher risk of neonatal mortality and morbidity than those born by planned caesarean delivery. A hospital based non-experimental comparison of outcome of breech delivery. Ife State Hospitals Complex, Ile-Ife. Two hundred and fourty four singleton breech deliveries occurring at term. They include low 5-minute Apgar score, birth trauma, maternal and perinatal morbidity and mortality. The perinatal mortality was not significantly different in both groups: OR 2.7 (95% C.I. 0.3-26.8). The low 5-minute Apgar scores were higher in the planned vaginal delivery OR 9.0 (95% C.I. 1-73.4), but the traumatic morbidity was not (OR 1.8, 95% C.I. 0.2-20.1). Maternal morbidity occurred more in the planned Caesarean delivery group OR 0.4 (95% C.I. 0.2-0.9). Given appropriate selection criteria and management protocol, the outcome from elective caesarean section might not be better than from planned vaginal delivery.

The objective of this study was to rank U.S. occupations by worker morbidity. From 1986 through 1994, morbidity information was collected on over 410,000 U.S. workers who participated in the National Health Interview Survey, an annual household survey representative of the U.S. civilian noninstitutionalized population. A multivariate adjusted logistic regression morbidity summary score was created for each worker group based on seven indicators: days of restricted activity, bedrest, and missed work in the previous 2 weeks; doctor visits and hospitalizations in the previous 12 months; reported health conditions; and health status. Worker groups reporting the greatest morbidity included social workers, inspectors, postal clerks, psychologists, and grinding machine operators; worker groups reporting the least morbidity included dentists, pilots, physicians, pharmacists, and dietitians. These findings aid in the identification of worker groups that require increased attention for morbidity research and prevention.

Background On 30 September 2009, a 7.6 magnitude earthquake severely hit the coast of Padang city in West Sumatra, Indonesia leaving about 1,117 people dead and injuring another 3,515. Health consequences such as physical injury, co-morbidity, disability and quality of life over time are seldom reported among survivors after earthquakes. Objectives To investigate the associations between injury, disability and quality of life amongst adult survivors in Padang city after the 2009 earthquake. Design/Methods A prospective cohort study was conducted to compare adult injured (184) and adult non-injured (93) subjects over a 6-month period. Data on physical injury, co-morbidities, disability and quality of life were collected through interviews and measured quantitatively in three phases, i.e. at baseline, end of 3 and 6 months. Results Disability scores were consistently and significantly higher among injured subjects compared to non-injured, even when adjusted for co-morbidities (i.e. acute symptoms and chronic diseases). The highest disability score amongst injured subjects was attributed to ‘feeling discomfort/pain’. Quality of life attribute (QLA) scores, were significantly lower amongst injured people as compared to those non-injured even when adjusted for co-morbidities. The lowest QLA item score amongst the injured was ‘pain, depression and anxiety’. Significant and consistent negative correlations were found between disability and QLA scores in both the injured and non-injured groups. Conclusion Physical injury is significantly correlated with both higher disability and lower quality of life, while disability has significant negative correlation with quality of life. The findings suggest that, through disability, injury may contribute to decreased quality of life. It is therefore recommended to promptly and adequately treat injuries after disasters to prevent any potential for disability and hence restore quality of life. PMID:22629236

Objective The goal of this study is to determine the effect of primary surgery vs radiotherapy (RT) on overall survival (OS) in patients with early stage oral cavity squamous cell carcinoma (OCSCC). In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

Purpose: To model late fecal incontinence after high-dose prostate cancer radiotherapy (RT) in patients accrued in the AIROPROS (prostate working group of the Italian Association of Radiation Oncology) 0102 trial using different endpoint definitions. Methods and Materials: The self-reported questionnaires (before RT, 1 month after RT, and every 6 months for {<=}3 years after RT) of 586 patients were available. The peak incontinence (P{sub I}NC) and two longitudinal definitions (chronic incontinence [C{sub I}NC], defined as the persistence of Grade 1 or greater incontinence after any Grade 2-3 event; and mean incontinence score [M{sub I}NC], defined as the average score duringmore » the 3-year period after RT) were considered. The correlation between the clinical/dosimetric parameters (including rectal dose-volume histograms) and P{sub I}NC (Grade 2 or greater), C{sub I}NC, and M{sub I}NC of {>=}1 were investigated using multivariate logistic analyses. Receiver operating characteristic curves and the area under the curve were used to assess the predictive value of the different multivariate models. Results: Of the 586 patients, 36 with a Grade 1 or greater incontinence score before RT were not included in the present analysis. Of the 550 included patients, 197 (35.8%) had at least one control with a Grade 1 or greater incontinence score (M{sub I}NC >0). Of these 197 patients, 37 (6.7%), 22 (4.0%), and 17 (3.1%) were scored as having P{sub I}NC, M{sub I}NC {>=}1, and C{sub I}NC, respectively. On multivariate analysis, Grade 2 or greater acute incontinence was the only predictor of P{sub I}NC (odds ratio [OR], 5.9; p = .0009). Grade 3 acute incontinence was predictive of C{sub I}NC (OR, 9.4; p = .02), and percentage of the rectal volume receiving >40 Gy of {>=}80% was predictive of a M{sub I}NC of {>=}1 (OR, 3.8; p = .008) and of C{sub I}NC (OR, 3.6; p = .03). Previous bowel disease, previous abdominal/pelvic surgery, and the use of antihypertensive (protective factor) correlated highly with both C{sub I}NC and M{sub I}NC {>=}1. The predictive values of the models for C{sub I}NC (area under the curve, 0.83) and M{sub I}NC {>=}1 (area under the curve, 0.73) were greater than the ones for P{sub I}NC (area under the curve, 0.62) and more reliable (p = .0001-.0003 against p = .02). Nomograms for the two longitudinal definitions were derived. Conclusions: The longitudinal definitions of fecal incontinence (C{sub I}NC and M{sub I}NC {>=}1) were helpful in accounting for both the persistence and the severity of the incontinence. A significant fraction of peak events was consequential to acute incontinence, and a longer duration of symptoms mainly depended on the rectal dose bath (percentage of rectal volume receiving >40 Gy), and pretreatment clinical factors.« less

The aim was to describe health literacy among the older population of Kosovo, an Albanian speaking post-war country in the Western Balkans, in the context of self-perceived health status and self-reported chronic morbidity. A cross-sectional study was conducted in Kosovo in 2011 including 1753 individuals aged ≥ 65 years (886 men, 867 women; mean age 73.4 ± 6.3 years; response rate: 77%). Participants were asked to assess, on a scale from 1 to 5, their level of difficulty with regard to access, understanding, appraisal and application of health information. Sub-scale scores and an overall health literacy score were calculated for each participant. Information on self-perceived health status, presence and number of chronic diseases and socioeconomic characteristics was also collected. Mean values of the overall health literacy score and all sub-scale scores (access, understanding, appraisal and application) were lower among older people who reported a poorer health status or at least one chronic condition compared with individuals who perceived their health status as good or had no chronic conditions (p < 0.001 for all). Our findings provide valuable evidence on the independent and inverse association between health literacy levels and self-perceived health and chronic morbidity in this post-war European population. The putative link with chronic morbidity and lower adherence to health services is hard to establish through this cross-sectional study. Prospective population-based studies should be conducted in Kosovo and other transitional settings to replicate these findings and properly address the causal relationship between health literacy and health status. © The Author (2014).

Our recent review of the literature uncovered eleven obesity-specific quality of life questionnaires, all with incomplete demonstration of their measurement properties. Our objective was to validate a new self-administered questionnaire specific to morbid obesity to be used in clinical trials. The study was carried out at the bariatric surgery clinic of Laval Hospital, Quebec City, Canada. This study followed our description of health-related quality of life in morbid obesity from which we constructed the Laval Questionnaire. Its construct validity and responsiveness were tested by comparing the baseline and changes at 1-year follow-up in 6 domain scores (symptoms, activity/mobility, personal hygiene/clothing, emotions, social interactions, sexual life) with those of questionnaires measuring related constructs (SF-36, Impact of Weight on Quality of Life-Lite, Rosenberg Self-Esteem Scale and Beck Depression Inventory-II). 112 patients (67 who got bariatric surgery, 45 who remained on the waiting list during the study period) participated in this study. The analysis of the discriminative function of the questionnaire showed moderate-to-high correlations between the scores in each domain of our instrument and the corresponding questionnaires. The analysis of its evaluative function showed (1) significant differences in score changes between patients with bariatric surgery and those without, and (2) moderate-to-high correlations between the changes in scores in the new instrument and the changes in the corresponding questionnaires. Most of these correlations met the a priori predictions we had made regarding their direction and magnitude. The Laval Questionnaire is a valid measure of health-related quality of life in patients with morbid obesity and is responsive to treatment-induced changes.

Olfactory abilities of the patients are known to be altered by eating and metabolic disorders, including obesity. There are only a number of studies investigating the effect of obesity on olfaction, and there is limited data on the changes in olfactory abilities of morbidly obese patients after surgical treatment. Here we investigated the changes in olfactory abilities of 54 morbidly obese patients (M/F, 22/32; age range 19-57 years; body mass index (BMI) range 30.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. A laparoscopic sleeve gastrectomy was performed by the same surgeon using five-port technique. Olfactory abilities were tested preoperatively and 1, 3, and 6 months after the surgery using a standardized Sniffin' Sticks Extended Test kit. Analyses of variance indicated statistically significant improvement in T, D, and I scores of morbidly obese patients within time factors (preoperative vs. 1, 3, and 6 months; 1 vs. 3 and 6 months; and 3 vs. 6 months; p < 0.001 for all). There was a statistically significant improvement in overall TDI scores with an increase from 25 to 41 during the 6 months follow-up period (p < 0.001 for all). Here, for the first time in literature, we were able to show the significant improvement in olfactory abilities of morbidly obese patients after laparoscopic sleeve gastrectomy.

The high prevalence of morbidity among female physicians in Hungary is well documented, however, little is known about the prevalence of that in certain age groups. To assess the prevalence of somatic and psychiatric morbidity in two age cohorts (Cohort 1: age 24-43 and Cohort 2: age 44-76) of female physicians and to explore the relationship between morbidity and potential risk factors including work-related stressors. Representative, cross-sectional, quantitative survey among representative samples of female physicians (N = 408). Physicians in Cohort 1 reported more frequent night shift rotation, less leisure time, and fewer days off compared to physicians in Cohort 2. Physicians in Cohort 1 were less satisfied with their work, workplace, reported less support from their colleagues, and received lower salary compared to physicians in Cohort 2. Physicians in Cohort 1 scored significantly higher on the emotional exhaustion and the personal accomplishment scales MBI as compared to Cohort 2 physicians. In Cohort 1 emotional exhaustion and personal accomplishment were associated with high depression scores and frequent suicidal ideation. The role of emotional exhaustion is decisive of young physicians' well-being. Future research should focus on understanding the psycho-social, individual, organizational, and societal correlates of the high prevalence of morbidity among young female physicians in Hungary.

Axillary lymph node dissection (ALND) as part of surgical treatment in breast cancer has been the standard procedure for many decades. However, patients frequently develop shoulder-arm morbidity postoperatively. Recently, sentinel node (SN) biopsy has been established as a new standard of care for axillary staging in breast cancer. This study compares postoperative morbidity between ALND and SN biopsy. The results are compared with the existing literature. Between November 2000 and September 2002, 181 women with early stage breast cancer underwent primary surgery following preoperative randomisation into two groups, a "standard group" (SN biopsy was followed by ALND) and a study group (surgical procedure consisting of only SN biopsy when histologically metastasis-free SN was present). Follow-up data (362 sessions; 6 months to 3 years after primary surgery) were available from 150 patients. A summary morbidity score was calculated from four subjective (arm-strength, arm-mobility, arm swelling, pain) and four objective (arm-strength, arm-mobility, lymphedema, sensitivity) criteria. Fifty seven patients underwent SN biopsy only. Ninety three patients underwent ALND, 57 of which had lymph nodes free of metastasis and 36 had lymph nodes with metastasis and axillary clearing. Shoulder-arm morbidity was significantly different between the groups. Patients treated with SN biopsy only scored better on subjective and objective criteria. Postsurgical shoulder-arm morbidity is a major long-term problem in patients undergoing surgical treatment for breast cancer. This prospective study showed significantly less severe shoulder-arm morbidity following SN biopsy compared to patients undergoing ALND.

Zagar, Timothy M., E-mail: zagar@med.unc.edu; Kaidar-Person, Orit; Tang, Xiaoli

Purpose: To evaluate early cardiac single photon computed tomography (SPECT) findings after left breast/chest wall postoperative radiation therapy (RT) in the setting of deep inspiration breath hold (DIBH). Methods and Materials: We performed a prospective single-institution single-arm study of patients who were planned for tangential RT with DIBH to the left breast/chest wall (± internal mammary nodes). The DIBH was done by use of a controlled surface monitoring technique (AlignRT, Vision RT Ltd, London, UK). The RT was given with tangential fields and a heart block. Radiation-induced cardiac perfusion and wall motion changes were assessed by pre-RT and 6-month post-RTmore » SPECT scans. A cumulative SPECT summed-rest score was used to quantify perfusion in predefined left ventricle segments. The incidence of wall motion abnormalities was assessed in each of these same segments. Results: A total of 20 patients with normal pre-RT scans were studied; their median age was 56 years (range, 39-72 years). Seven (35%) patients also received irradiation to the left internal mammary chain, and 5 (25%) received an additional RT field to supraclavicular nodes. The median heart dose was 94 cGy (range, 56-200 cGy), and the median V25{sub Gy} was zero (range, 0-0.1). None of the patients had post-RT perfusion or wall motion abnormalities. Conclusions: Our results suggest that DIBH and conformal cardiac blocking for patients receiving tangential RT for left-sided breast cancer is an effective means to avoid early RT-associated cardiac perfusion defects.« less

Radiation therapy (RT) is a treatment modality traditionally used in patients with multiple myeloma (MM), but little is known regarding the role and effectiveness of RT in the era of novel agents, i.e., immunomodulatory drugs and proteasome inhibitors. We retrospectively reviewed data from 449 consecutive MM patients seen at our institute in 2010-2012 to assess indications for RT as well as its effectiveness. Pain response was scored similarly to RTOG 0631 and used the Numerical Rating Pain Scale. Among 442 evaluable patients, 149 (34%) patients and 262 sites received RT. The most common indication for RT was palliation of bone pain (n = 109, 42%), followed by prevention/treatment of pathological fractures (n = 73, 28%), spinal cord compression (n = 26, 10%), and involvement of vital organs/extramedullary disease (n = 25, 10%). Of the 55 patients evaluable for pain relief, complete and partial responses were obtained in 76.4 and 7.2%, respectively. Prior RT did not significantly decrease the median number of peripheral blood stem cells collected for autologous transplant, even when prior RT was given to both the spine and pelvis. Inadequacy of stem cell collection for autologous stem cell transplant (ASCT) was not significantly different and it occurred in 9 and 15% of patients receiving no RT and spine/pelvic RT, respectively. None of the three cases of therapy-induced acute myelogenous leukemia/MDS occurred in the RT group. Despite the introduction of novel effective agents in the treatment of MM, RT remains a major therapeutic component for the management in 34% of patients, and it effectively provides pain relief while not interfering with successful peripheral blood stem cell collection for ASCT.

During the last 20 years, waiting lists for renal transplantation (RT) have grown significantly older. However, elderly patients (ie ≥65 years of age) are still more rarely referred or accepted to waiting lists and, if enlisted, have less chances of actually receiving a kidney allograft, than younger counterparts. In this review, we looked at evidence for the benefits and risks of RT in the elderly trying to answer the following questions: Should RT be advocated for elderly patients? What should be the criteria to accept elderly patients on the waiting list for RT? What strategies might be used to increase the rate of RT in waitlisted elderly candidates? For selected elderly patients, RT was shown to be superior to dialysis in terms of patient survival. Virtually all guidelines recommend that patients should not be deemed ineligible for RT based on age alone, although a short life expectancy generally might preclude RT. Concerning the assessment of comorbidities in the elderly, special attention should be paid to cardiac evaluation and screening for malignancy. Comorbidity scores and frailty assessment scales might help the decision making on eligibility. Psychosocial issues should also be evaluated. To overcome the scarcity of organ donors, elderly RT candidates should be encouraged to consider expanded criteria donors and living donors, as alternatives to deceased standard criteria donors. It has been demonstrated that expanded criteria donor RT in patients 60 years or older is associated with higher survival rates than remaining on dialysis, whereas living donor RT is superior to all other options.

The purpose of this study was to compare resistance exercise training (RT) to aerobic exercise training (AE) on the clinical risk factors for metabolic syndrome (MetSyn) in physically inactive overweight males (age 27-48 years). Subjects with at least one risk factor for MetSyn performed RT (n = 13, age 35.1 ± 4.7 years, BMI 31.2 ± 2.7 kg/m(2)) or AE (n = 9, age 37.6 ± 4.9 years, BMI, 31.2 ± 3.2 kg/m(2)) for 6 months. Training frequency and exercise session duration were equal and by 3 months the subjects exercised 4 day/week for 45 min/session. Blood lipids and glucose, waist circumference, and mean arterial blood pressure (MAP) were measured at 0, 3, and 6 months. A MetSyn z score was calculated for each subject from triglycerides, HDL cholesterol, fasting glucose, waist circumference, and MAP. Statistical significance was set at p ≤ 0.05. No significant differences existed between RT and AE groups at 0 month. AE showed a significant reduction in MetSyn z score from 0 (0.91 ± 3.57) to 6 months (-1.35 ± 2.95), while RT approached significance (p = 0.07) from 0 (0.09 ± 2.62) to 6 months (-1.30 ± 2.22). Triglycerides (mmol/L) significantly decreased in AE from 0 (1.93 ± 0.90) to 6 months (1.41 ± 0.70). Waist circumference (cm) significantly decreased in AE from 0 (106.8 ± 7.3) to 6 months (101.2 ± 6.5), and in RT from 0 (108.4 ± 9.0) to 6 months (105.7 ± 7.0). MAP (mmHg) decreased in RT from 0 (93.8 ± 5.8) to 6 months (87.5 ± 6.1) and in AE from 0 (97.6 ± 7.0) to 6 months (91.3 ± 6.8). With equal training frequency and exercise session duration, both RT and AE training, when paired with energy restriction improve the clinical risk factor profile for MetSyn.

Morbid obesity is rising around the world. It can cause unpleasant appearance and body image. Most of the studies have aimed to evaluate the psychopathology of overweight and obesity and paying attention to mental well-being in morbid obese individuals is rare. Therefore, this study aimed to assess the relationship between body image and psychological well-being in morbid obese patients. This cross-sectional study, using simple random sampling method, was done on 124 morbid obese patients who referred to obesity clinic in Shiraz from 2016 to 2017. The data were collected by body image index and psychological well-being questionnaire. Results were analyzed using descriptive statistics, Pearson correlation coefficient test, ANOVA, and Regression analysis. The results showed a significant relationship between body image and psychological well-being (r=0.43) (P<0.001), and between the total score of the body image and all the subscales of psychological well-being except autonomy and purpose in life (P<0.05). There was also a significant relationship between the total score of psychological well-being and all the subscales of body image (P<0.05). However, there was no significant difference between the mean scores of the body image and those of psychological well-being in different categories of body mass index (BMI) (P>0.05). Final results indicated that body image defects caused by obesity could lie in negative psychological well-being in all aspects. This study can promote health clinicians' knowledge in supporting of mental status of obese individuals. It is suggested that preventing and supporting intervention should be performed as effective methods for encountering and coping with psychological effects of obesity.

Status epilepticus (SE) is a neurological emergency, characterized by high short-term morbidity and mortality. We evaluated and compared two scores that have been developed to evaluate status epilepticus prognosis: STESS (Status Epilepticus Severity Score) and EMSE (Epidemiology based Mortality score in Status Epilepticus). A prospective observational study was performed on consecutive patients with SE admitted between September 2013 and August 2015. Demographics, clinical variables, STESS-3 and -4, and EMSE-64 scores were calculated for each patient at baseline. SE drug response, 30-day mortality and morbidity were the outcomes measure. 162 episodes of SE were observed: 69% had a STESS ≥3; 34% had a STESS ≥4; 51% patients had an EMSE ≥64. The 30-days mortality was 31.5%: EMSE-64 showed greater negative predictive value (NPV) (97.5%), positive predictive value (PPV) (59.8%) and accuracy in the prediction of death than STESS-3 and STESS-4 (p<0.001). At 30 days, the clinical condition had deteriorated in 59% of the cases: EMSE-64 showed greater NPV (71.3%), PPV (87.8%) and accuracy than STESS-3 and STESS-4 (p<0.001) in the prediction of this outcome. In 23% of all cases, status epilepticus proved refractory to non-anaesthetic treatment. All three scales showed a high NPV (EMSE-64: 87.3%; STESS-4: 89.4%; STESS-3: 87.5%) but a low PPV (EMSE-64: 40.9%; STESS-4: 52.9%; STESS-3: 32%) for the prediction of refractoriness to first and second line drugs. This means that accuracy for the prediction of refractoriness was equally poor for all scales. EMSE-64 appears superior to STESS-3 and STESS-4 in the prediction of 30-days mortality and morbidity. All scales showed poor accuracy in the prediction of response to first and second line antiepileptic drugs. At present, there are no reliable scores capable of predicting treatment responsiveness.

We sought to assess the safety, effectiveness and cost of 0.6 mg/kg rt-PA treatment for patients with acute mild stroke and to compare that with 0.9 mg/kg. We retrospectively analyzed consecutive acute ischemic stroke patients who had a NIHSS score ≤5 at admission and who were treated with rt-PA within 4.5 hours of symptom onset. The demographic data, clinical outcomes and hospitalization cost were analyzed. A total of 108 patients were included. Forty six patients (42.6%) received a 0.6 mg/kg dosage of rt-PA. The baseline characteristics of the two groups were well matched (p > 0.05). Regarding the safety and effectiveness, the 0.6 mg/kg dosage group had a comparable proportion of symptomatic intracranial hemorrhage (sICH) (0.6 mg/kg, 4.3% vs 0.9 mg/kg, 4.8%; p > 0.05), early neurological deterioration (END) (19.6% vs 17.7%; p > 0.05), in-hospital mortality (4.3% vs 1.6%; p > 0.05), and a similar rate of favorable functional outcome (mRS score 0-1) at 3 months (73.9% vs 71.0%; p > 0.05) to those who received the standard dosage. However, the hospital cost was markedly lower in the 0.6 mg/kg group (0.6  mg/kg, 3,401.7 USD vs 0.9  mg/kg, 4,157.4 USD; p < 0.01). Our study suggest that 0.6 mg/kg rt-PA shared similar effectiveness and safety profile compared with that of 0.9 mg/kg in treating mild stroke, but cost less.

Purpose: Primary bone lymphoma (PBL) represents less than 1% of all malignant lymphomas. In this study, we assessed the disease profile, outcome, and prognostic factors in patients with Stages I and II PBL. Patients and Methods: Thirteen Rare Cancer Network (RCN) institutions enrolled 116 consecutive patients with PBL treated between 1987 and 2008 in this study. Eighty-seven patients underwent chemoradiotherapy (CXRT) without (78) or with (9) surgery, 15 radiotherapy (RT) without (13) or with (2) surgery, and 14 chemotherapy (CXT) without (9) or with (5) surgery. Median RT dose was 40 Gy (range, 4-60). The median number of CXT cyclesmore » was six (range, 2-8). Median follow-up was 41 months (range, 6-242). Results: The overall response rate at the end of treatment was 91% (complete response [CR] 74%, partial response [PR] 17%). Local recurrence or progression was observed in 12 (10%) patients and systemic recurrence in 17 (15%). The 5-year overall survival (OS), lymphoma-specific survival (LSS), and local control (LC) were 76%, 78%, and 92%, respectively. In univariate analyses (log-rank test), favorable prognostic factors for OS and LSS were International Prognostic Index (IPI) score {<=}1 (p = 0.009), high-grade histology (p = 0.04), CXRT (p = 0.05), CXT (p = 0.0004), CR (p < 0.0001), and RT dose >40 Gy (p = 0.005). For LC, only CR and Stage I were favorable factors. In multivariate analysis, IPI score, RT dose, CR, and CXT were independently influencing the outcome (OS and LSS). CR was the only predicting factor for LC. Conclusion: This large multicenter retrospective study confirms the good prognosis of early-stage PBL treated with combined CXRT. An adequate dose of RT and complete CXT regime were associated with better outcome.« less

Purpose: More than 70% of Ewing tumors occur in the extremities and pelvis. This study identified factors influencing local control and functional outcomes after management with definitive radiotherapy (RT). Patients and Methods: A total of 75 patients with a localized Ewing tumor of the extremity or pelvis were treated with definitive RT at the University of Florida between 1970 and 2006 (lower extremity tumors in 30, pelvic tumors in 26, and upper extremity tumors in 19). RT was performed on a once-daily (40%) or twice-daily (60%) basis. The median dose was 55.2 Gy in 1.8-Gy daily fractions or 55.0 Gymore » in 1.2-Gy twice-daily fractions. The median observed follow-up was 4.7 years. Functional outcome was assessed using the Toronto Extremity Salvage Score. Results: The 10-year actuarial overall survival, cause-specific survival, freedom from relapse, and local control rate was 48%, 48%, 42%, and 71%, respectively. Of the 72 patients, 3 required salvage amputation. Inferior cause-specific survival was associated with larger tumors (81% for tumors <8 cm vs. 39% for tumors {>=}8 cm, p <0.05). No patient characteristics or treatment variables were predictive of local failure. No fractures occurred in patients treated with hyperfractionation or with tumors of the distal extremities. Severe late complications were more frequently associated with use of <8-MV photons and fields encompassing the entire bone or hemipelvis. A significantly better Toronto Extremity Salvage Score was associated with a late-effect biologically effective dose of <91.7 Gy{sub 3}. Conclusions: Limb preservation was effectively achieved through definitive RT. Treating limited field sizes with hyperfractionated high-energy RT could minimize long-term complications and provides superior functional outcomes.« less

Specific perioperative risk assessment models have been developed for bariatric, pancreatic, and colorectal surgery. A similar instrument, specific for patients with critical limb ischemia (CLI), could improve patient-centered clinical decision making. We describe a novel tool to predict 30-day major morbidity and mortality (M&M) after bypass surgery for CLI. Data for 4985 individuals from the 2007 to 2009 National Surgical Quality Improvement Program were used to develop and internally validate the model. Outcome measures included mortality, major morbidity, and a composite end point (M&M). M&M included mortality and the most severe postoperative morbidities that were highly associated with death (eg, sepsis and major cardiopulmonary complications). More than 30 preoperative factors were tested for association with 30-day mortality, major morbidity, and M&M. Significant predictors in multivariate models were assigned integer values (points), which were added to calculate a patient's Comprehensive Risk Assessment For Bypass (CRAB) score. Performance was assessed (C-index) across all outcome measures and compared with other general tools (American Society of Anesthesiologists class, Surgical Risk Scale) and existing CLI-specific survival prediction models (Finnvasc score, Edifoligide for the Prevention of Infrainguinal Vein Graft Failure [PREVENT III] score) on a distinct validation sample (n = 1620). In the derivation data set (n = 3275), the 30-day mortality rate was 2.9%. The rate of any major morbidity was 19.1%. The composite end point M&M occurred in 10.1%. Significant predictors of M&M by multivariate analysis included age >75 years, prior amputation or revascularization, tissue loss, dialysis dependence, severe cardiac disease, emergency operation, and functional dependence. Applied to a distinct validation sample of 1620 patients, higher CRAB scores were significantly associated with higher rates of mortality, all major morbidities, and M&M (P < .0001). Comparison with other models by assessment of area under the receiver-operating characteristic curve revealed the CRAB was a more accurate predictor of mortality, all major morbidity, and M&M. The CRAB is a CLI-specific, risk assessment instrument derived from multi-institutional American College of Surgeons-National Surgical Quality Improvement Program surgical outcomes data that out-performs existing prognostic risk indices in the prediction of clinically significant adverse events after bypass surgery. Use of the CRAB as a risk assessment tool provides an evidence basis for patient-centered clinical decision making and may have a role in identifying patients at higher risk for surgical revascularization in whom an endovascular approach is preferable.

This study examines the ability of the distress thermometer to accurately identify patients with higher symptoms, unmet needs and psychological morbidity. Baseline data collected as part of a randomized controlled trial evaluating a nurse-led supportive care intervention for men with prostate cancer commencing radiotherapy at a specialist cancer hospital in Melbourne, Australia. Measures assessed global distress (DT), anxious and depressive symptomatology (HADS), prostate-cancer specific quality of life (EPIC-26), unmet supportive care needs (SCNS-SF34R) and cancer treatment-related concerns (CATS). Following descriptive and correlational analysis, hierarchical multiple regression was employed to examine the contribution of variable sets to explaining variance in DT scores. Less than 20% of men reported DT scores of 4 or higher, indicating overall low distress. The DT accurately identified almost all men reporting HADS score indicative of anxious or depressive symptomatology, suggesting it accurately identifies psychological morbidity. Importantly, the DT identified a further group of distressed men, not identified by HADS, whose distress related to unmet needs and prostate cancer-specific issues, indicating the DT is superior in identifying other forms of distress. While the hierarchical multiple regression confirmed anxious and depressive symptomatology as the best predictor of distress score, many other scales are also good predictors of DT scores, supporting the argument that distress is multi-determined. Nurses can be confident that the DT accurately identifies patients with psychological morbidity and importantly identifies other patients with distress who may require intervention. A distress score of 4 or higher identified participants with higher physical symptomatology, higher unmet needs, more concerns about treatment and poorer quality of life. The low prevalence of distress reaching cut off scores suggests nurses would not be overwhelmed by the outcomes of screening and could use the score to prioritise the patients who need greater attention at entry to radiotherapy services.

Aortic occlusion is a potentially valuable tool for early resuscitation in patients nearing extremis or in arrest from severe hemorrhage. The American Association for the Surgery of Trauma's Aortic Occlusion in Resuscitation for Trauma and Acute Care Surgery registry identified trauma patients without penetrating thoracic injury undergoing aortic occlusion at the level of the descending thoracic aorta (resuscitative thoracotomy [RT] or zone 1 resuscitative endovascular balloon occlusion of the aorta [REBOA]) in the emergency department (ED). Survival outcomes relative to the timing of CPR need and admission hemodynamic status were examined. Two hundred and eighty-five patients were included: 81.8% were males, with injury due to penetrating mechanisms in 41.4%; median age was 35.0 years (interquartile range 29 years) and median Injury Severity Score was 34.0 (interquartile range 18). Resuscitative thoracotomy was used in 71%, and zone 1 REBOA in 29%. Overall survival beyond the ED was 50% (RT 44%, REBOA 63%; p = 0.004) and survival to discharge was 5% (RT 2.5%, REBOA 9.6%; p = 0.023). Discharge Glasgow Coma Scale score was 15 in 85% of survivors. Prehospital CPR was required in 60% of patients with a survival beyond the ED of 37% and survival to discharge of 3% (all p > 0.05). Patients who did not require any CPR before had a survival beyond the ED of 70% (RT 48%, REBOA 93%; p < 0.001) and survival to discharge of 13% (RT 3.4%, REBOA 22.2%, p = 0.048). If aortic occlusion patients did not require CPR but presented with hypotension (systolic blood pressure <90 mmHg; 9% [65% RT; 35% REBOA]), they achieved survival beyond the ED in 65% (p = 0.009) and survival to discharge of 15% (RT 0%, REBOA 44%; p = 0.008). Overall, REBOA can confer a survival benefit over RT, particularly in patients not requiring CPR. Considerable additional study is required to definitively recommend REBOA for specific subsets of injured patients. Copyright © 2018 American College of Surgeons. Published by Elsevier Inc.

Improved understanding of soft-tissue sarcoma (STS) biology has led to better distinction and subtyping of these diseases with the hope of exploiting the molecular characteristics of each subtype to develop appropriately targeted treatment regimens. In the care of patients with extremity STS, adjunctive radiation therapy (RT) is used to facilitate limb and function, preserving surgeries while maintaining five-year local control above 85%. In contrast, for STS originating from nonextremity anatomical sites, the rate of local recurrence is much higher (five-year local control is approximately 50%) and a major cause of death and morbidity in these patients. Incorporating novel technological advancements to administer accurate RT in combination with novel radiosensitizing agents could potentially improve local control and overall survival. RT efficacy in STS can be increased by modulating biological pathways such as angiogenesis, cell cycle regulation, cell survival signaling, and cancer-host immune interactions. Previous experiences, advancements, ongoing research, and current clinical trials combining RT with agents modulating one or more of the above pathways are reviewed. The standard clinical management of patients with STS with pretreatment biopsy, neoadjuvant treatment, and primary surgery provides an opportune disease model for interrogating translational hypotheses. The purpose of this review is to outline a strategic vision for clinical translation of preclinical findings and to identify appropriate targeted agents to combine with radiotherapy in the treatment of STS from different sites and/or different histology subtypes.

ABSTRACT Acute bacterial meningitis is a medical emergency, and delays in initiating effective antimicrobial therapy result in increased morbidity and mortality. Culture-based methods, thus far considered the “gold standard” for identifying bacterial microorganisms, require 24 to 48 h to provide a diagnosis. In addition, antimicrobial therapy is often started prior to clinical sample collection, thereby decreasing the probability of confirming the bacterial pathogen by culture-based methods. To enable a fast and accurate detection of the most important bacterial pathogens causing meningitis, namely, Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Streptococcus agalactiae, and Listeria monocytogenes, we evaluated a commercially available multiplex LightMix real-time PCR (RT-PCR) in 220 cerebrospinal fluid (CSF) specimens. The majority of CSF samples were collected by lumbar puncture, but we also included some CSF samples from patients with symptoms of meningitis from the neurology department that were recovered from shunts. CSF samples were analyzed by multiplex RT-PCR enabling a first diagnosis within a few hours after sample arrival at our institute. In contrast, bacterial identification took between 24 and 48 h by culture. Overall, a high agreement of bacterial identification between culture and multiplex RT-PCR was observed (99%). Moreover, multiplex RT-PCR enabled the detection of pathogens, S. pneumoniae (n = 2), S. agalactiae (n = 1), and N. meningitidis (n = 1), in four culture-negative samples. As a complement to classical bacteriological CSF culture, the LightMix RT-PCR assay proved to be valuable by improving the rapidity and accuracy of the diagnosis of bacterial meningitis.

The Aristotle Comprehensive Complexity (ACC) and the Risk Adjustment in Congenital Heart Surgery (RACHS-1) scores have been proposed for complexity adjustment in the analysis of outcome after congenital heart surgery. Previous studies found RACHS-1 to be a better predictor of outcome than the Aristotle Basic Complexity score. We compared the ability to predict operative mortality and morbidity between ACC, the latest update of the Aristotle method and RACHS-1. Morbidity was assessed by length of intensive care unit stay. We retrospectively enrolled patients undergoing congenital heart surgery. We modeled each score as a continuous variable, mortality as a binary variable, and length of stay as a censored variable. We compared performance between mortality and morbidity models using likelihood ratio tests for nested models and paired concordance statistics. Among all 1,384 patients enrolled, 30-day mortality rate was 3.5% and median length of intensive care unit stay was 3 days. Both scores strongly related to mortality, but ACC made better prediction than RACHS-1; c-indexes 0.87 (0.84, 0.91) vs 0.75 (0.65, 0.82). Both scores related to overall length of stay only during the first postoperative week, but ACC made better predictions than RACHS-1; U statistic=0.22, p<0.001. No significant difference was noted after adjusting RACHS-1 models on age, prematurity, and major extracardiac abnormalities. The ACC was a better predictor of operative mortality and length of intensive care unit stay than RACHS-1. In order to achieve similar performance, regression models including RACHS-1 need to be further adjusted on age, prematurity, and major extracardiac abnormalities.

The Post-operative Morbidity Index (PMI) is a quantitative utility measure of a complication burden created by severity weighting. The Fistula Risk Score (FRS) is a validated model that predicts whether a patient will develop a post-operative pancreatic fistula (POPF). These novel tools might provide further discrimination of the ISGPF grading system. From 2001 to 2012, 1021 pancreaticoduodenectomies were performed at four institutions. POPFs were categorized by ISGPF standards. PMI scores were calculated based on the Modified Accordion Severity Grading System. FRS scores were assigned according to the relative influence of four recognized factors for developing a clinically relevant POPF (CR-POPF). In total, 231 patients (22.6%) developed a POPF, of which 54.1% were CR-POPFs. The PMI differed significantly between the ISGPF grades and patients with no or non-fistulous complications (P < 0.001). 64.9% of POPFs and 84.0% of CR-POPFs contributed the highest Accordion grade to the PMI. Overall, the FRS correlated well with PMI (R(2) = 0.81, P < 0.001). These data quantitatively reinforce the ISGPF grades that were developed qualitatively around the concept of clinical severity. CR-POPFs usually reflect the patient's highest Accordion score whereas biochemical POPFs are often superseded. The correlation between FRS and PMI indicates that risk factors for a fistula contribute to overall pancreaticoduodenectomy morbidity. © 2013 International Hepato-Pancreato-Biliary Association.

Obesity has been linked to increased morbidity and mortality after some surgical procedures. The purpose of this study was to determine whether obesity affects outcome after general neurosurgery and subarachnoid hemorrhage (SAH). Three data sets were analyzed, including a retrospective review of 404 patients undergoing cranial and spinal neurosurgical procedures, a prospective collection of 100 patients with aneurysmal SAH, and data from 3567 patients with aneurysmal SAH who were entered into randomized clinical trials of tirilazad. For each data set, outcome was assessed by mortality, postoperative morbidity, and Glasgow Outcome Scale score. Prognostic factors, including body weight and body mass index, were tested for their effect on these outcomes using multivariable logistic regression. For patients undergoing general cranial and spinal neurosurgery, independent predictors of morbidity and mortality were age, American Society of Anesthesia class, disseminated malignancy, emergency surgery, and increased duration of surgery. For patients with SAH, score on the Glasgow Outcome Scale was associated with age and admission Glasgow Coma Scale score. In the tirilazad data set, multiple factors were associated with score on the Glasgow Outcome Scale, but, as with the other 2 data sets, body weight had no relationship to outcome. Obesity may have less effect on the outcome of patients with mainly cranial neurosurgical disease and aneurysmal SAH than it does on patients undergoing other types of surgery.

Aiming for minimal toxicity after radical prostate cancer (PC) radiotherapy (RT), magnetic resonance imaging (MRI) target delineation could be a possible benefit knowing that clinical target volumes (CTV) are up to 30% smaller, when CTV delineation on MRI is compared to standard computed tomography (CT). This study compares long-term toxicity using CT or MRI delineation before PC RT. Urinary and rectal toxicity assessments 36 months after image-guided RT (78 Gy) using CTC-AE scores in two groups of PC patients. Peak symptom score values were registered. One group of patients (n=72) had standard CT target delineation and gold markers as fiducials. Another group of patients (n=73) had MRI target delineation and a nickel-titanium stent as fiducial. At 36 months no difference in overall survival (92% in both groups, p=0.29) or in PSA-relapse free survival was found between the groups (MRI=89% and CT=94%, p=0.67). A significantly smaller CTV was found in the MRI group (p=0.02). Urinary retention and frequency were significantly reduced in the MRI group (p=0.03 in the matter of both). The overall urinary and rectal toxicity did not differ between the two groups. MRI delineation leads to a significantly reduced CTV. Significantly lower urinary frequency and urinary retention toxicity scores were observed following MRI delineation. The study did not find significant differences in overall urinary or rectal toxicity between the two groups. PSA-relapse survival did not differ between the two groups at 36 months.

Purpose: The benefit of adding androgen deprivation therapy (ADT) to dose-escalated radiation therapy (RT) for men with intermediate-risk prostate cancer is unclear; therefore, we assessed the impact of adding ADT to dose-escalated RT on freedom from failure (FFF). Methods: Three groups of men treated with intensity modulated RT or 3-dimensional conformal RT (75.6-78 Gy) from 1993-2008 for prostate cancer were categorized as (1) 326 intermediate-risk patients treated with RT alone, (2) 218 intermediate-risk patients treated with RT and ≤6 months of ADT, and (3) 274 low-risk patients treated with definitive RT. Median follow-up was 58 months. Recursive partitioning analysis basedmore » on FFF using Gleason score (GS), T stage, and pretreatment PSA concentration was applied to the intermediate-risk patients treated with RT alone. The Kaplan-Meier method was used to estimate 5-year FFF. Results: Based on recursive partitioning analysis, intermediate-risk patients treated with RT alone were divided into 3 prognostic groups: (1) 188 favorable patients: GS 6, ≤T2b or GS 3+4, ≤T1c; (2) 71 marginal patients: GS 3+4, T2a-b; and (3) 68 unfavorable patients: GS 4+3 or T2c disease. Hazard ratios (HR) for recurrence in each group were 1.0, 2.1, and 4.6, respectively. When intermediate-risk patients treated with RT alone were compared to intermediate-risk patients treated with RT and ADT, the greatest benefit from ADT was seen for the unfavorable intermediate-risk patients (FFF, 74% vs 94%, respectively; P=.005). Favorable intermediate-risk patients had no significant benefit from the addition of ADT to RT (FFF, 94% vs 95%, respectively; P=.85), and FFF for favorable intermediate-risk patients treated with RT alone approached that of low-risk patients treated with RT alone (98%). Conclusions: Patients with favorable intermediate-risk prostate cancer did not benefit from the addition of ADT to dose-escalated RT, and their FFF was nearly as good as patients with low-risk disease. In patients with GS 4+3 or T2c disease, the addition of ADT to dose-escalated RT did improve FFF.« less

The optimal method of reconstruction following mastectomy for breast cancer patients receiving radiation therapy (RT) is controversial. This study evaluated patient satisfaction and complication rates among patients who received implant-based breast reconstruction. The specific treatment algorithm analyzed included patients receiving mastectomy and immediate temporary tissue expander (TE), followed by placement of a permanent breast implant (PI). If indicated, RT was delivered to the fully expanded TE. Records of 218 consecutive patients with 222 invasive (85%) or in situ (15%) breast lesions from the Salt Lake City region treated between 1998 and 2009 were retrospectively reviewed, 28% of whom received RT. Median RT dose was 50.4 Gy, and 41% received a scar boost at a median dose of 10 Gy. Kaplan-Meier analyses were performed to evaluate the cumulative incidence of surgical complications, including permanent PI removal. Risk factors associated with surgical events were analyzed. To evaluate cosmetic results and patient satisfaction, an anonymous survey was administered. Mean follow-up was 44 months (range 6-144). Actuarial 5-year PI removal rates for non-RT and RT patients were 4% and 22%, respectively. On multivariate analysis (MVA), the only factor associated with PI removal was RT (p = 0.009). Surveys were returned describing the outcomes of 149 breasts. For the non-RT and RT groups, those who rated their breast appearance as good or better were 63% versus 62%, respectively. Under 1/3 of each group was dissatisfied with their reconstruction. RT did not significantly affect patient satisfaction scores, but on MVA RT was the only factor associated with increased PI removal. This reconstruction technique may be considered an acceptable option even if RT is needed, but the increased complication risk with RT must be recognized. © 2015 Wiley Periodicals, Inc.

Purpose: The optimal sequencing of adjuvant chemotherapy (CT) and radiation therapy (RT) in patients with early-stage breast cancer remains unclear. Patients and Methods: We retrospectively compared 485 patients treated with conservative breast surgery and postoperative whole-breast RT and six courses of CMF (cyclophosphamide 600 mg/m{sup 2}, methotrexate 40 mg/m{sup 2}, and 5-fluorouracil 600 mg/m{sup 2}) with 300 patients who received postoperative CMF only and with 509 patients treated with postoperative whole-breast RT only. The mean radiation dose delivered was 50 Gy (range, 46-52 Gy) with standard fractionation. The boost dose was 6-16 Gy according to resection margins and at themore » discretion of the radiation oncologist. Acute and late RT toxicity were scored using respectively the Radiation Therapy Oncology Group and the Late Effects in Normal Tissues Subjective, Objective, Management and Analytic scale. Results: A slightly higher Grade 2 acute skin toxicity was recorded in the concurrent group (21.2% vs. 11.2% of the RT only group, p < 0.0001). RT was interrupted more frequently in the CMF/RT group respective to the RT group (8.5% vs. 4.1%; p = 0.006). There was no difference in late toxicity between the two groups. All patients in the concurrent group successfully received the planned dose of RT and CT. Local recurrence rate was 7.6% in CT/RT group and 9.8% in RT group; this difference was not statistically significant at univariate analysis (log-rank test p = 0.98). However, at multivariate analysis adjusted also for pathological tumor, pathological nodes, and age, the CT/RT group showed a statistically lower rate of local recurrence (p = 0.04). Conclusions: Whole-breast RT and concurrent CMF are a safe adjuvant treatment in terms of toxicity.« less

Psychiatric morbidity in human immunodeficiency virus (HIV) patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ), mini mental status examination, hospital anxiety and depression scale (HADS) and sensation seeking scale (SSS) and the scores were analyzed statistically. Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

Objective As part of a randomized, double-blind, placebo-controlled study, we examined the antidepressant action of oral chamomile (Matricaria recutita) extract in subjects with co-morbid anxiety and depression symptoms. We hypothesized that chamomile may demonstrate a clinically meaningful antidepressant activity versus placebo. Methods 57 subjects received either chamomile extract or placebo therapy. Nineteen subjects had anxiety with co-morbid depression, 16 had anxiety with past history of depression, and 22 had anxiety with no current or past depression. Generalized estimating equations analysis was used to identify clinically meaningful changes over time in Hamilton Depression Rating (HAM-D) rating outcome measures among treatment groups. Results We observed a significantly greater reduction in mean total HAM-D scores (p<0.05) and HAM-D core depression item score (p<0.05) for chamomile versus placebo in all subjects, and a non-significant trend for a greater reduction in HAM-D core depression score for chamomile versus placebo in subjects with anxiety with current co-morbid depression (p=0.062). Conclusion Chamomile may have clinically meaningful antidepressant activity that occurs in addition to its previously observed anxiolytic activity. PMID:22894890

Objectives. To determine in-hospital mortality and complications of cardiac surgery in pediatric patients and identify predictors of hospital mortality. Methods. Records of pediatric patients who had undergone cardiac surgery in 2005 were reviewed retrospectively. The risk adjustment for congenital heart surgery (RACHS-1) method, the Aristotle basic complexity score (ABC score), and the Society of Thoracic Surgeons and the European Association for Cardiothoracic Surgery Mortality score (STS-EACTS score) were used as measures. Potential predictors were analyzed by risk analysis. Results. 230 pediatric patients had undergone congenital cardiac surgery. Overall, the mortality discharge was 6.1%. From the ROC curve of the RACHS-1, the ABC level, and the STS-EACTS categories, the validities were determined to be 0.78, 0.74, and 0.67, respectively. Mortality risks were found at the high complexity levels of the three tools, bypass time >85 min, and cross clamp time >60 min. Common morbidities were postoperative pyrexia, bleeding, and pleural effusion. Conclusions. Overall mortality and morbidities were 6.1%. The RACHS-1 method, ABC score, and STS-EACTS score were helpful for risk stratification. PMID:21738856

Hospitalization in chronic heart failure patients associated with high mortality and morbidity rate. The 90 days post-discharge period following hospitalization in heart failure patients is known as the vulnerable phase, it carries the high risk of poor outcomes. Identification of high-risk individuals by using prognostic evaluation was intended to do a closer follow up and more intensive to decreasing the morbidity and mortality rate of heart failure.To determine whether PREDICE score could predict mortality within 90 days in patients with heart failure, an observational cohort study in patients with heart failure who were hospitalized due to worsening chronic heart failure. Patients were in following-up for up to 90 days after initial evaluation with the primary endpoint is death.We found a difference of the significantstatistical between PREDICE score in survival and mortality group (p=0.001) of 84% (95% CI: 60.9% - 97.4%).In conclusion, PREDICE score has a good ability to predict mortality within 90 days in patients with heart failure.

Critical early thrombolytic and endovascular reperfusion therapy for acute ischemic stroke victims: a call for adjunct neuroprotection.

PubMed

Lapchak, Paul A

2015-10-01

Today, there is an enormous amount of excitement in the field of stroke victim care due to the recent success of MR. CLEAN, SWIFT PRIME, ESCAPE, EXTEND-IA, and REVASCAT endovascular trials. Successful intravenous (IV) recombinant tissue plasminogen activator (rt-PA) clinical trials [i.e., National Institute of Neurological Disorders and Stroke (NINDS) rt-PA trial, Third European Cooperative Acute Stroke Study (ECASSIII), and Third International Stroke study (IST-3)] also need to be emphasized. In the recent endovascular and thrombolytic trials, there is statistically significant improvement using both the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Score (mRS) scale, but neither approach promotes complete recovery in patients enrolled within any particular NIHSS or mRS score tier. Absolute improvement (mRS 0-2 at 90 days) with endovascular therapy is 13.5-31 %, whereas thrombolytics alone also significantly improve patient functional independence, but to a lesser degree (NINDS rt-PA trial 13 %). This article has 3 main goals: (1) first to emphasize the utility and cost-effectiveness of rt-PA to treat stroke; (2) second to review the recent endovascular trials with respect to efficacy, safety, and cost-effectiveness as a stroke treatment; and (3) to further consider and evaluate strategies to develop novel neuroprotective drugs. A thesis will be put forth so that future stroke trials and therapy development can optimally promote recovery so that stroke victims can return to "normal" life.

We compared the image quality of free-breathing diffusion-weighted imaging (FB-DWI) to that of respiratory-triggered DWI (RT-DWI) after proper optimization. Three healthy subjects were scanned to optimize magnetic resonance (MR) parameters of FB-DWI to improve image quality, including spatial resolution, image noise, and chemical shift artifacts. After this optimization, we scanned 32 patients with liver disease to assess the clinical feasibility of the optimized FB-DWI. Of the 32 patients, 14 had a total of 28 hepatocellular carcinomas (HCCs), four had a total of 15 metastatic liver tumors, and the other 14 had no tumor. Qualitatively, we compared the image quality scores of FB-DWI with those of RT-DWI with the Wilcoxon signed-rank test. Quantitatively, we compared the signal-to-noise ratios (SNRs) of the liver parenchyma, lesion-to-nonlesion contrast-to-noise ratios (CNRs) and apparent diffusion coefficient (ADC) values of the liver parenchyma and liver tumor by the paired t-test. The average scores of image quality for sharpness of liver contour, image noise, and chemical shift artifacts were significantly higher for FB-DWI than RT-DWI (P < 0.05). SNRs, CNRs, and ADC values of the liver parenchyma and tumors did not differ significantly between the 2 DWI methods. Compared with RT-DWI, the optimized FB-DWI provided better spatial resolution, fewer artifacts, and comparable SNRs, lesion-to-nonlesion CNRs, and ADC values.

Purpose Magnetic resonance imaging-guided radiation therapy (MRgRT) requires patient positioning within the MR bore and prolonged MR imaging during delivery, both of which are new in radiation oncology. Patient tolerance of MRgRT was prospectively evaluated using patient-reported outcome questionnaires (PRO-Q). Methods Our MRgRT procedure involves daily high-resolution MR scanning, limited re-contouring, daily plan re-optimization, quality assurance (QA), and gated delivery. Patients with claustrophobia are excluded. Mean fraction duration was 45 and 60 minutes for stereotactic treatments during free-breathing and breath-hold, respectively. Patient-controlled video-feedback was used for breath-hold delivery. PRO-Qs collected in the first 150 patients treated included questions on MR-related complaints and also evaluated aspects of active participation. Results Almost one-third of patients (29%) scored at least one PRO-Q item on MR-related complaints as ‘moderate’ or ‘very much’, with noise, feeling cold, and paresthesia being the most frequently scored in this way. Considerable anxiety was reported by 5%, but no medication was required for this in any patient. Patient participation in video feedback for breath-hold delivery was appreciated by the majority of patients, all of whom completed the procedure. Only 5% of patients considered treatment duration to be unacceptably long. Conclusion Despite the lengthy MRgRT procedure, outcomes of PRO-Q indicate that it was well-tolerated by patients.

Purpose: The safety of antioxidant supplementation during radiation therapy (RT) for cancer is controversial. Antioxidants could potentially counteract the pro-oxidant effects of RT and compromise therapeutic efficacy. We performed a prospective study nested within the Physicians' Health Study (PHS) randomized trial to determine if supplemental antioxidant use during RT for prostate cancer is associated with an increased risk of prostate cancer death or metastases. Methods and Materials: PHS participants (383) received RT for prostate cancer while randomized to receive beta-carotene (50 mg on alternate days) or placebo. The primary endpoint was time from RT to lethal prostate cancer, defined asmore » prostate cancer death or bone metastases. The Kaplan-Meier method was used to estimate survival probabilities and the log-rank test to compare groups. Cox proportional hazards regression was used to estimate the effect of beta-carotene compared with that of placebo during RT. Results: With a median follow-up of 10.5 years, there was no significant difference between risk of lethal prostate cancer with the use of beta-carotene during RT compared with that of placebo (hazard ratio = 0.72; 95% confidence interval [CI], 0.42-1.24; p = 0.24). After we adjusted for age at RT, prostate-specific antigen serum level, Gleason score, and clinical stage, the difference remained nonsignificant. The 10-year freedom from lethal prostate cancer was 92% (95% CI, 87-95%) in the beta-carotene group and 89% (95% CI, 84-93%) in the placebo group. Conclusion: The use of supplemental antioxidant beta-carotene during RT was not associated with an increased risk of prostate cancer death or metastases. This study suggests a lack of harm from supplemental beta-carotene during RT for prostate cancer.« less

The current study examined competing predictions of the default mode, cognitive neuroenergetic, and functional working memory models of attention-deficit/hyperactivity disorder (ADHD) regarding the relation between neurocognitive impairments in working memory and intraindividual variability. Twenty-two children with ADHD and 15 typically developing children were assessed on multiple tasks measuring intraindividual reaction time (RT) variability (ex-Gaussian: tau, sigma) and central executive (CE) working memory. Latent factor scores based on multiple, counterbalanced tasks were created for each construct of interest (CE, tau, sigma) to reflect reliable variance associated with each construct and remove task-specific, test-retest, and random error. Bias-corrected, bootstrapped mediation analyses revealed that CE working memory accounted for 88% to 100% of ADHD-related RT variability across models, and between-group differences in RT variability were no longer detectable after accounting for the mediating role of CE working memory. In contrast, RT variability accounted for 10% to 29% of between-group differences in CE working memory, and large magnitude CE working memory deficits remained after accounting for this partial mediation. Statistical comparison of effect size estimates across models suggests directionality of effects, such that the mediation effects of CE working memory on RT variability were significantly greater than the mediation effects of RT variability on CE working memory. The current findings question the role of RT variability as a primary neurocognitive indicator in ADHD and suggest that ADHD-related RT variability may be secondary to underlying deficits in CE working memory.

For patients who develop brain metastases from solid tumors, age, KPS, primary tumor status and presence of extracranial metastases have been identified as prognostic factors. However, the factors that affect survival in patients who are deemed fit to undergo resection of brain metastases have not been clearly elucidated hitherto. This is a retrospective analysis of a prospectively maintained database. All patients who underwent resection of intracranial metastases from solid tumors were included. Various patient, disease and treatment related factors were analyzed to assess their impact on survival. Overall, 124 patients had undergone surgery for brain metastases from various primary sites. The median age and pre-operative performance score were 53 years and 80 respectively. Synchronous metastases were resected in 17.7% of the patients. The postoperative morbidity and mortality rates were 17.7% and 2.4% respectively. Adjuvant whole brain radiation was received by 64 patients. At last follow-up, 8.1% of patients had fresh post-surgical neurologic deficits. The median progression free and overall survival were 6.91 was 8.56 months respectively. Surgical resection of for brain metastases should be considered in carefully selected patients. Gross total resection and receiving adjuvant whole brain RT significantly improves survival in these patients. Copyright © 2018 Elsevier B.V. All rights reserved.

Cardiovascular disease is the most prevalent age-related illness worldwide, causing approximately 15 million deaths every year. Hypertension is central in determining cardiovascular risk and is a strong predictive indicator of morbidity and mortality; however, there remains an unmet clinical need for disease-modifying and prophylactic interventions. Enhanced sympathetic activity is a well-established contributor to the pathophysiology of hypertension, however the cellular and molecular changes that increase sympathetic neurotransmission are not known. The aim of this study was to identify key changes in the transcriptome in normotensive and spontaneously hypertensive rats. We validated 15 of our top-scoring genes using qRT-PCR, and network and enrichment analyses suggest that glutamatergic signalling plays a key role in modulating Ca 2+ balance within these ganglia. Additionally, phosphodiesterase activity was found to be altered in stellates obtained from the hypertensive rat, suggesting that impaired cyclic nucleotide signalling may contribute to disturbed Ca 2+ homeostasis and sympathetic hyperactivity in hypertension. We have also confirmed the presence of these transcripts in human donor stellate samples, suggesting that key genes coupled to neurotransmission are conserved. The data described here may provide novel targets for future interventions aimed at treating sympathetic hyperactivity associated with cardiovascular disease and other dysautonomias.

We report short and long-term results with the dedicated Synthes(®) titanium plates system, introduced 5 years ago, for chest wall stabilization and reconstruction. We retrospectively analyzed (January 2010 to December 2014) 27 consecutive patients (22 males, 5 females; range 16-83 years, median age 60 years), treated with this system: primary [3] and secondary [8] chest wall tumor; flail chest [5]; multiple ribs fractures [5]; sternal dehiscence-diastasis [3]; sternal fracture [1]; sternoclavicular joint dislocation [1]; Poland syndrome [1]. Short-term results were evaluated as: operating time, post-operative morbidity, mortality, hospital stay; long-term results as: survival, plates-related morbidity, spirometric values, chest pain [measured with Verbal Rating Scale (VRS) and SF12 standard V1 questionnaire]. Each patient received from 1 to 10 (median 2) titanium plates/splints; median operating time was 150 min (range: 115-430 min). Post-operative course: 15 patients (55.6%) uneventful, 10 (37%) minor complications, 2 (7.4%) major complications; no post-operative mortality. Median post-operative hospital stay was 13 days (range: 5-129 days). At a median follow-up of 20 months (range: 1-59 months), 21 patients (78%) were alive, 6 (22%) died. Three patients presented long-term plates-related morbidity: plates rupture [2], pin plate dislodgment [1]; two required a second surgical look. One-year from surgery median spirometric values were: FVC 3.31 L (90%), FEV1 2.46 L (78%), DLCO 20.9 mL/mmHg/min (76%). On 21 alive patients, 7 (33.3%) reported no pain (VRS score 0), 10 (47.6%) mild (score 2), 4 (19.1%) moderate (score 4), no-one severe (score >4); 15 (71.5%) reported none or mild, 6 (28.5%) moderate pain influencing quality of life. An optimal chest wall stabilization and reconstruction was achieved with the Synthes(®) titanium plates system, with minimal morbidity, no post-operative mortality, acceptable operating time and post-operative hospital stay. Long-term restoration of a normal respiratory function was achieved, with minimal plates-related morbidity and chest pain.

Acute bacterial meningitis (ABM) remains a significant cause of pediatric illness and death in low and middle income countries. Identifying severity risk factors and predictive scores may guide interventions to reduce poor outcomes. Data from a prospective surveillance study for ABM in children aged 0-59 months admitted to 3 referral hospitals in Guatemala City from 2000 to 2007 were analyzed. ABM was defined as positive cerebrospinal fluid (CSF) culture, positive latex agglutination or CSF white blood cell greater than 100 cells/mL. Univariate and multivariate analyses of risk factors at hospital admission that predicted major morbidity or death during hospitalization were performed, along with validation of the predictive Herson-Todd score (HTS). Of 809 children with ABM episodes, 221 (27.3%) survived with major morbidity and 192 (23.7%) died. Among 383 children with nonmissing data, the most significant multivariate predictors for death or major morbidity were seizure [odds ratio (OR), 101.5; P < 0.001], CSF glucose less than 20 mg/dL (OR, 5.3; P = 0.0004), symptom duration more than 3 days (OR, 3.7; P = 0.003) and coma (OR, 6.3; P = 0.004). Of 221 children with a HTS greater than 5, 204 (92%) died or suffered major morbidity (OR, 10.3; P < 0.0001). ABM is a cause of considerable morbidity and mortality in Guatemala. Several clinical risk factors and the composite HTS predicted death or major morbidity. These predictors could help clinicians in low and middle income country guide medical care for ABM and could contribute to the public health impact assessment in preventing meningitis with vaccines.

Evaluate the effects of a low-intensity resistance training (LI-RT) program associated with partial blood flow restriction on selected clinical outcomes in patients with knee osteoarthritis (OA). Forty-eight women with knee OA were randomized into one of the three groups: LI-RT (30% one repetition maximum [1-RM]) associated (blood flow restriction training [BFRT]) or not (LI-RT) with partial blood flow restriction, and high-intensity resistance training (HI-RT, 80% 1-RM). Patients underwent a 12-wk supervised training program and were assessed for lower-limb 1-RM, quadriceps cross-sectional area, functionality (timed-stands test and timed-up-and-go test), and disease-specific inventory (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]) before (PRE) and after (POST) the protocol. Similar within-group increases were observed in leg press (26% and 33%, all P < 0.0001), knee extension 1-RM (23% and 22%; all P < 0.0001) and cross-sectional area (7% and 8%; all P < 0.0001) in BFRT and HI-RT, respectively, and these were significantly greater (all P < 0.05) than those of LI-RT. The BFRT and HI-RT showed comparable improvements in timed-stands test (7% and 14%, respectively), with the latter showing greater increases than LI-RT. Timed-up-and-go test scores were not significantly changed within or between groups. WOMAC physical function was improved in BFRT and HI-RT (-49% and -42%, respectively; all P < 0.05), and WOMAC pain was improved in BFRT and LI-RT (-45% and -39%, respectively; all P < 0.05). Four patients (of 16) were excluded due to exercise-induced knee pain in HI-RT. Blood flow restriction training and HI-RT were similarly effective in increasing muscle strength, quadriceps muscle mass, and functionality in knee OA patients. Importantly, BFRT was also able to improve pain while inducing less joint stress, emerging as a feasible and effective therapeutic adjuvant in OA management.

This study aimed to evaluate the efficiency and the tolerance of radiation therapy (RT) on salivary glands in a large series of amyotrophic lateral sclerosis (ALS) patients with hypersalivation. Fifty ALS patients that had medically failure pretreatment were included in this prospective study. RT was delivered through a conventional linear accelerator with 6-MV photons and 2 opposed beams fields including both submandibular glands and two-thirds of both parotid glands. Total RT dose was 10 Gy in 2 fractions (n=30) or 20 Gy in 4 fractions (n=20). RT efficacy was assessed with the 9-grade Sialorrhea Scoring Scale (SSS), recently prospectively validated as the most effective and sensitive tool to measure sialorrhea in ALS patients. At the end of RT, all patients had improved: 46 had a complete response (92% CR, SSS 1-3) and 4 had a partial response (8% PR, SSS 4-5). A significant lasting salivary reduction was observed 6 months after RT completion: there was 71% CR and 26% PR, and there was a significant SSS reduction versus baseline (P<10(-6)). There was no grade 3 to 4 toxicity, and most side effects (34%) occurred during RT. Nine patients (18%) underwent a second salivary gland RT course, with a 3-months mean delay from the first RT, resulting in a SSS decrease (-77%). Both RT dose regimens induced a significant SSS decrease with no significant toxicity. There were, however, more patients with CR/PR in the 20-Gy protocol (P=.02), and 8 of 9 patients (89%) receiving a second RT course had previously been treated within the 10-Gy protocol. Radiation therapy of 20 Gy in 4 fractions is an efficient and safe treatment for ALS patients with sialorrhea. A shorter RT course (10 Gy in 2 fractions) may be proposed in patients in poor medical condition. Copyright © 2014 Elsevier Inc. All rights reserved.

This study aimed to systematically evaluate all reported outcomes of facial allotransplantation (FT) using the previously described FACES scoring instrument. This was a retrospective study of all consecutive face transplants to date (January 2012). Candidates were identified using medical and general internet database searches. Medical literature and media reports were reviewed for details regarding demographic, operative, anatomic, and psychosocial data, which were then used to formulate FACES scores. Pre-transplant and post-transplant scores for "functional status", "aesthetic deformity", "co-morbidities", "exposed tissue", and "surgical history" were calculated. Scores were statistically compared using paired-samples analyses. Twenty consecutive patients were identified, with 18 surviving recipients. The sample was composed of 3 females and 17 males, with a mean age of 35.0 ± 11.0 years (range: 19-57 years). Overall, data reporting for functional parameters was poor. Six subjects had complete pre-transplant and post-transplant data available for all 5 FACES domains. The mean pre-transplant FACES score was 33.5 ± 8.8 (range: 23-44); the mean post-transplant score was 21.5 ± 5.9 (range: 14-32) and was statistically significantly lower than the pre-transplant score (P = 0.02). Among the individual domains, FT conferred a statistically significant improvement in aesthetic defect scores and exposed tissue scores (P ≤ 0.01) while, at the same time, it displayed no significant increases in co-morbidity (P = 0.17). There is a significant deficiency in functional outcome reports thus far. Moreover, FT resulted in improved overall FACES score, with the most dramatic improvements noted in aesthetic defect and exposed tissue scores.

Dimensions and predictors of disability—A baseline study of patients entering somatic rehabilitation in secondary care

PubMed Central

2018-01-01

Purpose The purpose of this study was to investigate disability among patients who were accepted for admission to a Norwegian rehabilitation center and to identify predictors of disability. Materials and methods In a cross-sectional study including 967 adult participants, the World Health Organization Disability Assessment Schedule version 2.0 36-item version was used for assessing overall and domain-specific disability as outcome variables. Patients completed the Hospital Anxiety and Depression Scale (HADS), EuroQoL EQ-5D-5L and questions about multi-morbidity, smoking and perceived physical fitness. Additionally, the main health condition, sociodemographic and environmental variables obtained from referrals and public registers were used as predictor variables. Descriptive statistics and linear regression analyses were performed. Results The mean (standard error) overall disability score was 30.0 (0.5), domain scores ranged from 11.9 to 44.7. Neurological diseases, multi-morbidity, low education, impaired physical fitness, pain, and higher HADS depressive score increased the overall disability score. A low HADS depressive score predicted a lower disability score in all domains. Conclusions A moderate overall disability score was found among patients accepted for admission to a rehabilitation center but “life activities” and “participation in society” had the highest domain scores. This should be taken into account when rehabilitation strategies are developed. PMID:29499064

There is some evidence that Tourette syndrome is associated with cognitive disabilities. To examine the cognitive performance of a clinical cohort of children with Tourette syndrome. 266 children with Tourette syndrome have been examined with Wechsler Intelligence Scales. The presence of the co-morbidities attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD) was assessed using validated diagnostic instruments. Eighty healthy controls matched a part of the TS cohort. The children with Tourette syndrome had a mean verbal IQ (VIQ) of 92.9, performance IQ (PIQ) of 87.1, and full-scale IQ (FSIQ) of 88.8. We found statistically significant higher PIQ and FSIQ in the control group compared with a matched TS cohort and a trend towards a higher VIQ among the healthy controls. There was a statistically significant influence of age at onset of tics on PIQ. The children with co-morbid OCD scored higher on FSIQ compared with the other groups. The children with co-morbid ADHD and OCD showed problems in motor tasks and speed tasks and the children with co-morbid ADHD showed attention deficits. Children with Tourette syndrome have lower IQ scores than the general population (but less than one standard deviation below) and our control group. Early onset of tics and the presence of co-morbidities might cause specific deficits on cognitive performance. Copyright © 2010 European Paediatric Neurology Society. Published by Elsevier Ltd.

Majority of the health problems affecting school children are preventable by promotion of hygienic practices through proper health education by the teachers, who are the first contacts. The study was undertaken to find out the status of nutrition and personal hygiene among primary school children and their association with their varied morbidity profiles. A descriptive, observational, cross-sectional study was conducted in a primary school situated in the largest slum of Kolkata. The participants included 103 boys and 81 girls, with a mean age of 6.2 years. The mean personal hygiene score of the girls (4.15 ± 0.98) was significantly higher than that of boys (3.2 ± 1.4) [P<0.05]. Most of the boys (54.37%) and girls (74.07%) were normally nourished as per the CDC growth chart. Over 70% of the children were suffering from one or more morbidities, the most common morbidity in both the sexes being pallor, followed by worm infestation. Personal hygiene scores were significantly higher (P<0.05) among those children who were normally nourished as well as those who did not suffer from any morbidity in the last 15 days. Care should be taken to improve the pitiable state of personal hygiene and poor sanitary practices of these school children through coordinated and concerted health education measures by teachers as well as parents.

Optimal management of radiotherapy (RT) for intracranial germinoma remains controversial. This study was conducted to evaluate the long-term results of RT in patients with these tumors. The study group consisted of 126 patients with intracranial germinoma (50 patients with pathologically verified germinoma and 76 clinically diagnosed with germinoma by clinical and neuroradiologic signs) who were treated by RT alone between 1980 and 2001. The median age at diagnosis was 17 years (range, 2-47), and various radiation doses and treatment fields were used. Serum human chorionic gonadotropin (hCG) levels were elevated in 18 patients. The median follow-up of the 114 surviving patients was 122 months (range, 13-263). The 10-year actuarial overall survival and cause-specific survival rate for all patients was 90% and 95%, respectively. The 10-year actuarial cause-specific survival rate for patients with and without elevated hCG levels was 94%. Relapses were noted in 10 patients, 7 of whom died of the disease. No in-field relapses at primary sites were observed in 72 patients treated with total doses of 40-50 Gy. The incidence of spinal relapses was 4% (2 of 56) for patients treated with spinal irradiation and 3% (2 of 70) for those without spinal irradiation. After a median 10-year follow-up, 54 (92%) of 59 patients with tumors not involving the neurohypophyseal region and 42 (76%) of 55 patients with tumors involving the neurohypophyseal region had Karnofsky performance status scores of 90-100%. With regard to school education and occupation, 54 (92%) of 59 patients with tumors not involving the neurohypophyseal region and 39 (71%) of 55 patients with tumors involving the neurohypophyseal region were attending school or undertaking occupations. Hormonal replacement therapy was required in 50 (44%) of 114 surviving patients before RT; only 4 patients (4%), all with neurohypophyseal tumors, required hormonal replacement therapy after RT. Clinically evident severe neurocognitive dysfunctions were documented in 10 patients before RT, and no patients treated with total doses of <55 Gy developed apparent neurocognitive dysfunctions or other complications after RT. RT was a curative treatment for intracranial germinoma, and elevated serum hCG levels did not affect the prognosis of patients treated by RT alone. A total dose of 40-50 Gy to adequate treatment fields was effective in preventing intracranial relapse, and the incidence of spinal relapses was too low to warrant routine spinal irradiation. Karnofsky performance status scores, educational achievement, and the ability to work were generally good, particularly in patients with tumors that did not involve the neurohypophyseal region. Because most complications, such as hormonal deficiency and neurocognitive dysfunction, were documented before RT and newly diagnosed complications after RT were infrequent, the treatment toxicity faced by germinoma patients appears to be less than anticipated.

Reaction time and accuracy in individuals with aphasia during auditory vigilance tasks.

PubMed

Laures, Jacqueline S

2005-11-01

Research indicates that attentional deficits exist in aphasic individuals. However, relatively little is known about auditory vigilance performance in individuals with aphasia. The current study explores reaction time (RT) and accuracy in 10 aphasic participants and 10 nonbrain-damaged controls during linguistic and nonlinguistic auditory vigilance tasks. Findings indicate that the aphasic group was less accurate during both tasks than the control group, but was not slower in their accurate responses. Further examination of the data revealed variability in the aphasic participants' RT contributing to the lower accuracy scores.

Quantify neonatal morbidity by week of gestation for twins compared with singletons. We performed a population-based retrospective cohort study of all Ohio births from 2006 to 2007. Composite neonatal morbidity consisting of Apgar score < 7 at 5 minutes, assisted ventilation > 6 hours, neonatal transport, or seizures was compared between singletons and twins from 34 to 41 weeks. Neonatal morbidity was the lowest in twins delivered at 37 completed weeks and 2 weeks later for singletons at 39 weeks. Twin morbidity rapidly increased after 37 weeks and reached 15.8% at 41 weeks versus the singleton morbidity rate of 3.4% at 41 weeks. Twins delivered at 39 weeks and beyond were more than twice as likely to incur neonatal morbidity compared with singletons. The lowest rate of neonatal morbidity occurs at 37 weeks for twins versus 39 weeks for singleton births. The increased risk after 37 weeks for twins accelerates at a faster rate compared with that for singletons born past 39 weeks. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Risk models play an important role in stratification of patients for cardiac surgery, but their prognostic utilities for post-operative complications are rarely studied. We compared the EuroSCORE, EuroSCORE II, Society of Thoracic Surgeon's (STS) Score and an Australasian model (Aus-AVR Score) for predicting morbidities after aortic valve replacement (AVR), and also evaluated seven STS complications models in this context. We retrospectively calculated risk scores for 620 consecutive patients undergoing isolated AVR at Auckland City Hospital during 2005-2012, assessing their discrimination and calibration for post-operative complications. Amongst mortality scores, the EuroSCORE was the best at discriminating stroke (c-statistic 0.845); the EuroSCORE II at deep sternal wound infection (c=0.748); and the STS Score at composite morbidity or mortality (c=0.666), renal failure (c=0.634), ventilation>24 hours (c=0.732), return to theatre (c=0.577) and prolonged hospital stay >14 days post-operatively (c=0.707). The individual STS complications models had a marginally higher c-statistic (c=0.634-0.846) for all complications except mediastinitis, and had good calibration (Hosmer-Lemeshow test P-value 0.123-0.915) for all complications. The STS Score was best overall at discriminating post-operative complications and their composite for AVR. All STS complications models except for deep sternal wound infection had good discrimination and calibration for post-operative complications.

Time to foster a rational approach to preventing cardiovascular morbid events.

PubMed

Cohn, Jay N; Duprez, Daniel A

2008-07-29

Efforts to prevent atherosclerotic morbid events have focused primarily on risk factor prevention and intervention. These approaches, based on the statistical association of risk factors with events, have dominated clinical practice in the last generation. Because the cardiovascular abnormalities eventuating in morbid events are detectable in the arteries and heart before the development of symptomatic disease, recent efforts have focused on identifying the presence of these abnormalities as a more sensitive and specific guide to the need for therapy. Advances in noninvasive techniques for studying the vasculature and the left ventricle now provide the opportunity to use early disease rather than risk factors as the tool for clinical decision making. A disease scoring system has been developed using 10 tests of vascular and cardiac function and structure. More extensive data to confirm the sensitivity and specificity of this scoring system and to demonstrate its utility in tracking the response to therapy are needed to justify widespread application in clinical practice.

The United Kingdom Coordinating Committee on Cancer Research anal cancer trial demonstrated the benefit of combined modality treatment (CMT) using radiotherapy (RT), infusional 5-fluorouracil, and mitomycin C over RT alone. The present study retrospectively examines the impact of the recommended 6-week treatment gap and local RT boost on long-term outcome. A total of 577 patients were randomly assigned RT alone or CMT. After a 6-week gap responders received a boost using either additional external beam radiotherapy (EBRT) (15 Gy) or iridium-192 implant (25 Gy). The effect of boost, the gap between initial treatment (RT alone or CMT) and boost (Tgap), and overall treatment time (OTT) were examined for their impact on outcome. Among the 490 good responders, 436 (89%) patients received a boost after initial treatment. For boosted patients, the risk of anal cancer death decreased by 38% (hazard ratio [HR]: 0.62, 99% CI 0.35-1.12; p=0.04), but there was no evidence this was mediated via a reduction in locoregional failure (LRF) (HR: 0.90, 99% CI 0.48-1.68; p=0.66). The difference in Tgap was only 1.4 days longer for EBRT boost, compared with implant (p=0.51). OTT was longer by 6.1 days for EBRT (p=0.006). Tgap and OTT were not associated with LRF. Radionecrosis was reported in 8% of boosted, compared with 0% in unboosted patients (p=0.03). These results question the benefit of a radiotherapy boost after a 6-week gap. The higher doses of a boost may contribute more to an increased risk of late morbidity, rather than local control. Copyright © 2011 Elsevier Inc. All rights reserved.

Definitive, Preoperative, and Palliative Radiation Therapy of Esophageal Cancer.

2015-10-01

Long-term survival in patients with esophageal cancer remains dismal despite the recent improvements in surgery, the advances in radiotherapy (RT) technology, and the refinement of systemic treatments, including the advent of targeted therapies. Although surgery constitutes the treatment of choice for early-stage disease (stage I), a multimodal approach, including preoperative or definitive chemoradiotherapy (CRT) and perioperative chemotherapy, is commonly pursued in patients with locally advanced disease. A review of the literature was performed to assess the role of RT, alone or in combination with chemotherapy, in the management of esophageal cancer. Evidence from large, randomized phase III trials and meta-analyses supports the application of perioperative chemotherapy alone or preoperative concurrent CRT in patients with lower esophageal and esophagogastric junction adenocarcinomas. Preoperative CRT but not preoperative chemotherapy alone is now routinely used in patients with locally advanced squamous cell carcinoma (SCC). Additionally, definitive CRT without surgery has also emerged as a valuable approach in the management of resectable esophageal SCC to avoid surgery-related morbidity and mortality, whereas salvage surgery is reserved for those with persistent disease. Furthermore, brachytherapy offers a valuable option in the palliative treatment of patients with locally advanced, unresponsive disease. Fluorodeoxyglucose-positron emission tomography (FDG-PET) can facilitate a more accurate treatment response assessment and patient selection. Finally, the development of modern RT techniques, such as intensity-modulated and image-guided RT as well as FDG-PET-based RT planning, could further increase the therapeutic ratio of CRT. Altogether, CRT constitutes an important tool in the treatment armamentarium for esophageal cancer. Further optimization of CRT using modern technology and imaging, targeted therapies, and newer chemotherapeutic agents is a major challenge and should be the goal of future research and clinical trials.

The aim of this study was to assess effectiveness of balance training with a vibrotactile neurofeedback system in improving overall stability in patients with Parkinson's disease (PD). Ten patients diagnosed with idiopathic PD were included. Individualization of the rehabilitation program started with a body sway analysis of stance and gait tasks (Standard Balance Deficit Test, SBDT) by using the diagnostic tool of the applied device (Vertiguard(®)-RT). Those tasks with the poorest outcome as related to age- and gender-related controls were included in the training program (not more than six tasks). Improvement of postural stability was assessed by performing SBDT, Sensory Organization Test (SOT) of Computerized Dynamic Posturography (CDP), Dizziness Handicap Inventory (DHI), activity-specific balance confidence scale and recording the number of falls over the past three months. Furthermore, scores of SOT and DHI of 10 PD patients previously trained in an earlier study (by using CDP) were compared with results of those in the present study. After neurofeedback training (NFT), there was a statistically significant improvement in body sway (calculated over all training tasks), number of falls, and scores of SOT, DHI and ABC. In comparison with CDP-training, a statistically significant higher increase of SOT score was observed for patients after NFT with the Vertiguard-RT device compared to CDP training. Our results showed that a free-field vibrotactile NFT with Vertiguard(®)-RT device can improve balance in PD patients in everyday life conditions very effectively, which might led in turn to a reduction of falls.

To compare patient-reported xerostomia during daytime and during nighttime with objectively measured parotid and submandibular gland function in a cohort of head-and-neck cancer (HNC) patients treated with RT. A cohort of 138 HNC patients underwent objective measurements of parotid (PF) and submandibular (SMF) gland function and completed a xerostomia questionnaire (XQ) before RT, at 6 weeks, 6 months and 1 year after RT. No attempt was made to spare the submandibular gland(s). The XQ contained specific questions concerning the sensation of dry mouth during day- (XD) and nighttime (XN), scored on a 5-point Likert scale. Patients with no or mild (grade 1-3) xerostomia and patients with more severe (grade 4-5) complaints were grouped together. Before RT, no association existed between dry mouth complaints and PF or SMF. At 6 weeks, 6 months and 1 year after RT; 37%, 51% and 36% had grade 4-5 XD and 65%, 64% and 56% had grade 4-5 XN, respectively. Patients with grade 4-5 XD and XN had significantly worse SMF at all time points after RT compared to patients with grade 1-3 XD and XN, while PF was significantly worse only at 6 weeks after RT. In multivariate analyses, SMF was consistently the most important factor related to XN after treatment. PF significantly influenced XD at 6 weeks and 1 year after RT. Differentiating between complaints during day- and nighttime in xerostomia research is necessary. Dry mouth at night is a frequent problem after (parotid-sparing) RT for HNC and is explained by submandibular gland dysfunction. Sparing of the contralateral submandibular gland, in addition to parotid gland sparing, may result in improved patient-reported xerostomia. Copyright © 2012 Elsevier Ireland Ltd.

Purpose: The U.S. Preventive Services Task Force has recommended against screening men over 75 for prostate cancer. We examined whether older healthy men could benefit from aggressive prostate cancer treatment. Methods and Materials: 206 men with intermediate to high risk localized prostate cancer randomized to 70 Gy of radiation (RT) or RT plus 6 months of androgen suppression therapy (RT+AST) constituted the study cohort. Within subgroups stratified by Adult Comorbidity Evaluation-27 comorbidity score and age, Cox multivariable analysis was used to determine whether treatment with RT+AST as compared with RT was associated with a decreased risk of death. Results: Amongmore » healthy men (i.e., with mild or no comorbidity), 78 were older than the median age of 72.4 years, and in this subgroup, RT+AST was associated with a significantly lower risk of death on multivariable analysis (adjusted hazard ratio = 0.36 (95% CI=0.13-0.98), p = 0.046, with significantly lower 8-year mortality estimates of 16.5% vs. 41.4% (p = 0.011). Conversely, among men with moderate or severe comorbidity, 24 were older than the median age of 73, and in this subgroup, treatment with RT+AST was associated with a higher risk of death (adjusted hazard ratio = 5.2 (1.3-20.2), p = 0.018). Conclusion: In older men with mild or no comorbidity, treatment with RT+AST was associated with improved survival compared with treatment with RT alone, suggesting that healthy older men may derive the same benefits from prostate cancer treatment as younger men. We therefore suggest that prostate cancer screening recommendations should not be based on strict age cutoffs alone but should also take into account comorbidity.« less

Radiation Therapy Noncompliance and Clinical Outcomes in an Urban Academic Cancer Center

Ohri, Nitin; Rapkin, Bruce D.; Guha, Chandan

Purpose: To examine associations between radiation therapy (RT) noncompliance and clinical outcomes. Methods and Materials: We reviewed all patients who completed courses of external beam RT with curative intent in our department from the years 2007 to 2012 for cancers of the head and neck, breast, lung, cervix, uterus, or rectum. Patients who missed 2 or more scheduled RT appointments (excluding planned treatment breaks) were deemed noncompliant. Univariate, multivariable, and propensity-matched analyses were performed to examine associations between RT noncompliance and clinical outcomes. Results: Of 1227 patients, 266 (21.7%) were noncompliant. With median follow-up of 50.9 months, 108 recurrences (8.8%) and 228more » deaths (18.6%) occurred. In univariate analyses, RT noncompliance was associated with increased recurrence risk (5-year cumulative incidence 16% vs 7%, P<.001), inferior recurrence-free survival (5-year actuarial rate 63% vs 79%, P<.001), and inferior overall survival (5-year actuarial rate 72% vs 83%, P<.001). In multivariable analyses that were adjusted for disease site and stage, comorbidity score, gender, ethnicity, race, and socioeconomic status (SES), RT noncompliance was associated with inferior recurrence, recurrence-free survival, and overall survival rates. Propensity score–matched models yielded results nearly identical to those seen in univariate analyses. Low SES was associated with RT noncompliance and was associated with inferior clinical outcomes in univariate analyses, but SES was not associated with inferior outcomes in multivariable models. Conclusion: For cancer patients being treated with curative intent, RT noncompliance is associated with inferior clinical outcomes. The magnitudes of these effects demonstrate that RT noncompliance can serve as a behavioral biomarker to identify high-risk patients who require additional interventions. Treatment compliance may mediate the associations that have been observed linking SES and clinical outcomes.« less

Mid-term shoulder functional and quality of life outcomes after shoulder replacement in obese patients.

Shoulder pain and loss of function are directly associated with obesity. We hypothesized that significant interactions would exist between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) and obesity status on functional and quality of life (QOL) outcomes over the long term. Clinical and QOL outcomes (American Shoulder and Elbow Surgeons Evaluation form, Shoulder Pain and Disability Index, University of California at Los Angeles Shoulder Rating scale, Medical Outcomes Short Form 12 (SF-12), range of motion (ROM), and strength) were longitudinally compared in patients with low and high body mass index (BMI) after a TSA or a RSA. Prospectively collected data of patients with a TSA or RSA were reviewed (N = 310). Preoperative, 2-year, and final follow-up visits were included (range 3-17 years; mean 5.0 ± 2.5 years). Patient data were stratified for analysis using BMI. Morbidly obese patients had worse preoperative functional scores and QOL compared to the other groups. There were no significant interactions of BMI group by surgery type for any of the outcome variables except for active external rotation ROM. Morbidly obese patients attained lower SF-12 scores compared to the remaining groups at each time point. Both TSA and RSA can be expected to impart positive functional outcomes in patients irrespective of BMI. Morbidly obese patients do not attain the same gains in Medical Outcomes SF-12 scores as the non-morbidly obese patients. The lower improvements in active external ROM may be due to morphological limitations of excessive adiposity. This is a level II study.

The major goal of surgical treatment in morbid obesity is to decrease morbidity and mortality associated with excess weight. In this sense, the main factors of death are cardiovascular disease and metabolic syndrome. The objective of this study is to evaluate the effects of gastric bypass on cardiovascular risk estimation in patients after bariatric surgery. We retrospectively evaluated pre and postoperative cardiovascular risk estimation of 402 morbidly obese patients who underwent laparoscopic gastric bypass. The major variable studied is the cardiovascular risk estimation that is calculated preoperatively and after 12 months. Cardiovascular risk estimation analysis has been performed with the REGICOR Equation. REGICOR formulation allows calculating a 10 year risk of cardiovascular events adapted to the Spanish population and is expressed in percentages. We reported an overall 4.1±3.0 mean basal REGICOR score. One year after the operation, cardiovascular risk estimation significantly decreased to 2,2±1,6 (P<.001). In patients with metabolic syndrome according to ATP-III criteria, basal REGICOR score was 4.8±3.1 whereas in no metabolic syndrome patients 2.2±1.8. Evaluation 12 months after surgery, determined a significant reduction in both groups (metabolic syndrome and non metabolic syndrome) with a mean REGICOR score of 2.3±1.6 and 1.6±1.0 respectively. The results of our study demonstrate favorable effects of gastric bypass on the cardiovascular risk factors included in the REGICOR equation. Copyright © 2013 AEC. Published by Elsevier Espana.

Only a few studies have been conducted with the objective of creating norms of the Alberta Infant Motor Scale (AIMS) for the assessment of gross motor development of preterm infants. The AIMS performance of preterm infants has been compared with that of the Canadian norms of full-term infants, but not with that of full-term infants of the same nationality. Moreover, the possible impact of prematurity-related morbidity factors on AIMS performance is unknown. The aims of this study were: (1) to evaluate AIMS trajectory in a large population of Greek preterm infants and create norms, (2) to compare it with the AIMS trajectory of Greek full-term infants, and (3) to examine the possible influence of neonatal morbidity on AIMS scores in the preterm sample. This was a cross-sectional study. Mean AIMS scores were compared, per month (1-19), between 403 preterm infants (≤32 weeks of age, corrected for prematurity) and 1,038 full-term infants. In preterm infants, the association of AIMS scores with respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH) of grade ≤III, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and sepsis was assessed by hierarchical regression analysis. Alberta Infant Motor Scale scores were significantly lower in preterm infants than in full-term infants. Mean AIMS scores in preterm infants were significantly associated with RDS (b=-1.93; 95% CI=-2.70, -1.16), IVH (b=-0.97; 95% CI=-1.69, -0.25), and ROP (b=-1.12; 95% CI=-1.99, -0.24) but not with BPD or sepsis in hierarchical regression analysis. Alberta Infant Motor Scale norms were created for Greek preterm infants. This study confirms that AIMS trajectories of preterm infants are below those of full-term infants of the same nationality. The influence of morbidity factors, including RDS, IVH, and ROP, should be taken into account when administering the AIMS in preterm infants. © 2016 American Physical Therapy Association.

Problematizing gender, work and health: the relationship between gender, occupational grade, working conditions and minor morbidity in full-time bank employees.

It is commonly asserted that while women have longer life expectancy than men, they have higher rates of morbidity, particularly for minor and psychological conditions. However, most research on gender and health has taken only limited account of the gendered distribution of social roles. Here we investigate gender differences in morbidity whilst controlling, as far as possible, for one major role, namely participation in paid employment. There is substantial segregation of the labour market by gender; men and women typically work different hours in different occupations which involve varying conditions and differing rewards and costs. Here, we examine men and women working full-time for the same employer. This paper reports on a postal survey of employees (1112 men and 1064 women) of a large British bank. It addresses three main questions: do gender differences in minor morbidity remain if we compare men and women who are employed in similar circumstances (same industry and employer)? What is the relative importance of gender, grade of employment within the organisation, perceived working conditions and orientation to gender roles for minor morbidity? Finally, are these factors related to health differentially for men and women? There were statistically significant gender differences amongst these full-time employees in recent experience of malaise symptoms, but not in physical symptoms or GHQ scores. Controlling for other factors did not reduce the gender differences in malaise scores and produced a weak, but significant, gender difference in GHQ scores. However, gender explained only a small proportion of variance, particularly in comparison with working conditions. Generally similar relationships between experience of work and occupational grade and morbidity were observed for men and women. Throughout the paper, we attempt to problematize gender, recognising that there are similarities between women and men and diversity amongst women and amongst men. However, we conclude that the gendered nature of much of adult life, including paid work, continues to shape the experiences and health of men and women at the end of the twentieth century.

To explore relationships of socio-demographic variables, health behaviours, environmental characteristics and personal factors, with physical and mental health variables in persons with morbid obesity, and to compare their health-related quality of life (HRQoL) scores with scores from the general population. A cross-sectional correlation study design was used. Data were collected by self-reported questionnaire from adult patients within the first 2 days of commencement of a mandatory educational course. Of 185 course attendees, 142 (76.8%) volunteered to participate in the study. Valid responses on all items were recorded for 128 participants. HRQoL was measured with the Short Form 12v2 from which physical (PCS) and mental component summary (MCS) scores were computed. Other standardized instruments measured regular physical activity, social support, self-esteem, sense of coherence, self-efficacy and coping style. Respondents scored lower on all the HRQoL sub-domains compared with norms. Linear regression analyses showed that personal factors that included self-esteem, self-efficacy, sense of coherence and coping style explained 3.6% of the variance in PCS scores and 41.6% in MCS scores. Personal factors such as self-esteem, sense of coherence and a high approaching coping style are strongly related to mental health in obese persons.

Use of the APACHE II score to assess impact of therapeutic plasma exchange for critically ill patients with hypertriglyceride-induced pancreatitis.

Hypertriglyceridemic (HTG) pancreatitis carries significant morbidity and mortality and often requires intensive care unit (ICU) admission. Therapeutic plasma exchange (TPE) rapidly lowers serum triglyceride (TG) levels. However, evidence supporting TPE for HTG pancreatitis is lacking. Ten patients admitted to the ICU for HTG pancreatitis underwent TPE at our institution from 2005-2015. We retrospectively calculated the Acute Physiology and Chronic Health Examination II (APACHE II) score at the time of initial TPE and again after the final TPE session to assess the impact of triglyceride apheresis on morbidity and mortality associated with HTG pancreatitis. All 10 patients had rapid reduction in TG level after TPE, but only 5 had improvement in their APACHE II score. The median APACHE II score decreased from 19% to 17% after TPE, correlating with an 8% and 9% decrease in median predicted non-operative and post-operative mortality, respectively. The APACHE II score did not differ statistically before and after TPE implementation in our patient group (p=0.39). TPE is a clinically useful tool to rapidly lower TG levels, but its impact on mortality of HTG pancreatitis as assessed by the APACHE II score remains uncertain. Copyright © 2016 Elsevier Ltd.

To investigate oral candidiasis in patients with head and neck cancer before, during, and after radiation therapy, and to explore its association with clinical oropharyngeal symptoms. A cohort study. University hospital. Subjects who received radiation therapy (RT) for the treatment of head and neck cancer were divided into two groups: an oral cavity irradiated group (OIRR group, n = 29) and an oral cavity nonirradiated group (ONIRR group, n = 17). A control group consisted of 18 healthy subjects. Patients were examined for signs of oral candidiasis before, during, immediately after, and one month after RT. Mouth and throat soreness (MTS), dysphagia, and xerostomia were evaluated by self-reported questionnaires, and associations between oral candidiasis and these symptoms were analyzed. The incidence of oral candidiasis during RT was significantly higher in the OIRR group (55.2%) than in the ONIRR group (11.8%). Similarly, the occurrence of xerostomia during RT was significantly higher in the OIRR group (86.2%) than in the ONIRR group (52.9%). In the OIRR group, the mean MTS score at the 20th fraction of RT was significantly higher in patients with candidiasis (mean +/- SD, 5.8 +/- 2.1) than in those with RT-induced mucositis without candidiasis (3.7 +/- 2.0). In the OIRR group, 65.2 percent of patients who experienced dysphagia developed oral candidiasis, compared with only 10 percent in the ONIRR group. Oral candidiasis concurrent with oral mucositis due to RT may increase oropharyngeal discomfort during RT. Copyright (c) 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

Bishop, Andrew J.; Zagars, Gunar K.; Moon, Bryan S.

Purpose: The purpose of this study was to investigate local control, survival outcomes, and complication rates of patients treated with limb-sparing surgery and radiation therapy (RT) for soft tissue sarcomas (STS) of the hands and feet. Methods and Materials: We reviewed the medical records of 85 consecutive patients treated for STS of the hands (n=38, 45%) and feet (n=47, 55%) between 1966 and 2012. The median age was 41 years (range, 10-82 years of age). Sixty-seven patients (79%) received postoperative RT after resection of their tumor (median dose, 60 Gy; range, 45-70 Gy). The remaining 18 patients (21%) were treated with preoperative RT followed by tumormore » resection (median dose, 50 Gy; range, 50-64 Gy). Results: Median follow-up was 140 months (range, 24-442 months). Five-year local control, overall survival, and disease-specific survival rates were 86%, 89%, and 89%, respectively. Positive or uncertain surgical margin status was the only factor adversely associated with local recurrence (19% vs 6% for negative margins, P=.046) but this lost significance on multivariate analysis when adjusting for RT dose ≥64 Gy. Of the 12 patients who had local relapses, 6 (50%) were salvaged, and only 2 of those required salvage amputation. Five patients had grade ≥3 late RT sequelae, with 2 patients (2%) having moderate limitations of limb function and 3 patients (4%) having severe limitations requiring procedures for skin ulceration. Conclusions: Limb-sparing surgery combined with RT provides excellent local control outcomes for sarcomas arising in the hands or feet. In patients who have local recurrence, salvage without amputation is possible. The excellent cancer control outcomes observed, considering the minimal impact on limb function, support use of combined modality, limb-sparing local therapy for STS arising in the hands or feet.« less

Positive or uncertain surgical margin status was the only factor adversely associated with local recurrence (19% vs 6% for negative margins, P=.046) but this lost significance on multivariate analysis when adjusting for RT dose ≥64 Gy. Of the 12 patients who had local relapses, 6 (50%) were salvaged, and only 2 of those required salvage amputation. Five patients had grade ≥3 late RT sequelae, with 2 patients (2%) having moderate limitations of limb function and 3 patients (4%) having severe limitations requiring procedures for skin ulceration. Limb-sparing surgery combined with RT provides excellent local control outcomes for sarcomas arising in the hands or feet. In patients who have local recurrence, salvage without amputation is possible. The excellent cancer control outcomes observed, considering the minimal impact on limb function, support use of combined modality, limb-sparing local therapy for STS arising in the hands or feet.

Summary Definitive chemoradiation (CRT) and laryngectomy followed by postoperative radiotherapy (RT) are both considered standard of care options for the management of advanced laryngeal cancer. While organ preservation with chemoradiotherapy is often the preferred up-front approach for appropriately selected candidates, the functional benefits of organ preservation must be carefully balanced against the considerable morbidity of salvage laryngectomy in patients who fail primary chemoradiation. Up-front identification of patients who are likely to require surgical salvage, therefore, is an important aim of any organ preserving approach in order to minimize morbidity while maximizing organ preservation. To this end, a strategy of “chemoselection”, using the primary tumor's response after one cycle of induction chemotherapy as an in vivo method of selecting responders for definitive chemoradiation while reserving primary surgical management for non-responders, has been employed extensively at our institution. The rationale, treatment results, and future directions of this approach are discussed. PMID:24053204

The role of pelvic elective nodal irradiation (ENI) in the management of prostate cancer is controversial. This study analyzed the role of pelvic radiation therapy (RT) on the outcome in high-risk localized prostate cancer patients included in the Groupe d'Etude des Tumeurs Uro-Genitales (GETUG) 12 trial. Patients with a nonpretreated high-risk localized prostate cancer and a staging lymphadenectomy were randomly assigned to receive either goserelin every 3 months for 3 years and 4 cycles of docetaxel plus estramustine or goserelin alone. Local therapy was administered 3 months after the start of systemic treatment. Performance of pelvic ENI was left to the treating physician. Only patients treated with primary RT were included in this analysis. The primary endpoint was biochemical progression-free survival (bPFS). A total of 413 patients treated from 2002 to 2006 were included, of whom 358 were treated using primary RT. A total of 208 patients received pelvic RT and 150 prostate-only RT. Prostate-specific antigen (PSA) concentration, Gleason score, or T stage did not differ according to performance of pelvic RT; pN+ patients more frequently received pelvic RT than pN0 patients (P<.0001). Median follow-up was 8.8 years. In multivariate analysis, bPFS was negatively impacted by pN stage (hazard ratio [HR]: 2.52 [95% confidence interval [CI]: 1.78-3.54], P<.0001), Gleason score 8 or higher (HR: 1.41 [95% CI: 1.03-1.93], P=.033) and PSA higher than 20 ng/mL (HR: 1.41 [95% CI: 1.02-1.96], P=.038), and positively impacted by the use of chemotherapy (HR: 0.66 [95% CI: 0.48-0.9], P=.009). There was no association between bPFS and use of pelvic ENI in multivariate analysis (HR: 1.10 [95% CI: 0.78-1.55], P=.60), even when analysis was restricted to pN0 patients (HR: 0.88 [95% CI: 0.59-1.31], P=.53). Pelvic ENI was not associated with increased acute or late patient reported toxicity. This unplanned analysis of a randomized trial failed to demonstrate a benefit of pelvic ENI on bPFS in high-risk localized prostate cancer patients. Copyright © 2016 Elsevier Inc.

In this study, the therapeutic efficacy of third-generation cephalosporins (3GCs) was compared with that of broader-spectrum β-lactams (BSBLs) [fourth-generation cephalosporins (4GCs) and carbapenems] as empirical therapy in adults with community-onset monomicrobial Enterobacteriaceae bacteraemia. Compared with those in the 3GC group (n = 477), a significantly higher proportion of patients in the BSBL group (n = 141) had initial presentation with severe sepsis or septic shock, critical illness (Pitt bacteraemia score ≥4) at bacteraemia onset and fatal co-morbidities (McCabe classification). For propensity score matching, 318 of the 477 patients in the 3GC group were matched with 106 patients in the BSBL group with the closest propensity scores on the basis of five independent predictors of 28-day mortality. After appropriate matching, no significant differences were observed in major baseline characteristics between the 3GC and BSBL groups in terms of causative micro-organism, bacteraemia severity, major source of bacteraemia, major co-morbidities and severity of co-morbidity. Consequently, the early clinical failure rate (12.9% vs. 12.3%; P = 0.87), bacteraemia severity (Pitt bacteraemia score ≥4; 4.6% vs. 8.2%; P = 0.17) at Day 3, and 3-day (3.8% vs. 7.5%; P = 0.11) and 28-day (13.2% vs. 17.0%; P = 0.33) crude mortality rates between the two groups were similar. These data suggest that the efficacy of 3GCs is similar to that of 4GCs or carbapenems when used as empirical antimicrobial therapy for community-onset Enterobacteriaceae bacteraemia.

Insulin resistance (IR) in adolescence is associated with type 2 diabetes mellitus [T2DM]. The PREVIEW (Prevention of Diabetes Through Lifestyle Intervention and Population Studies in Europe and Around the World) study assessed the effectiveness of a high-protein, low-glycaemic-index diet and a moderate-protein, moderate-glycaemic-index diet to decrease IR in insulin-resistant children who were overweight or obese. Inclusion criteria were age 10 to 17 years, homeostatic model assessment of IR (HOMA-IR) ≥2.0 and overweight/obesity. In 126 children (mean ± SD age 13.6 ± 2.2 years, body mass index [BMI] z-score 3.04 ± 0.66, HOMA-IR 3.48 ± 2.28) anthropometrics, fat mass percentage (FM%), metabolic characteristics, physical activity, food intake and sleep were measured. Baseline characteristics did not differ between the groups. IR was higher in pubertal children with morbid obesity than in prepubertal children with morbid obesity (5.41 ± 1.86 vs 3.23 ± 1.86; P = .007) and prepubertal and pubertal children with overweight/obesity (vs 3.61 ± 1.60, P = .004, and vs 3.40 ± 1.50, P < .001, respectively). IR was associated with sex, Tanner stage, BMI z-score and FM%. Fasting glucose concentrations were negatively associated with Baecke sport score (r = -0.223, P = .025) and positively with daytime sleepiness (r = 0.280, P = .016) independent of sex, Tanner stage, BMI z-score and FM%. In conclusion, IR was most severe in pubertal children with morbid obesity. The associations between fasting glucose concentration and Baecke sport score and sleepiness suggest these might be possible targets for diabetes prevention. © 2018 John Wiley & Sons Ltd.

The optimal initial local treatment for patients with Graves' ophthalmopathy (GO) is not fully characterized. The purpose of this retrospective study is to describe the clinical outcomes of RT as initial local therapy for GO and define predictors of the need for post-RT salvage bony decompressive surgery. 91 patients with active GO and without prior surgery were treated with RT as initial local therapy between 01/1999 and 12/2010, with a median follow-up period of 18.3 months (range 3.7 - 142 months). RT dose was 24 Gy in 12 fractions. 44 patients (48.4%) had prior use of steroids, with 31 (34.1%) being on steroids at the initiation of RT. The most common presenting symptoms were diplopia (79%), proptosis (71%) and soft tissue signs (62%). 84 patients (92.3%) experienced stabilization or improvement of GO symptoms. 58 patients (64%) experienced improvement in their symptoms. 19 patients (20.9%) underwent salvage post-RT bony decompressive surgery. Smoking status and total symptom score at 4 months were independent predictors of post-RT bony decompression with odds ratios of 3.23 (95% CI 1.03 - 10.2) and 1.59 (95% CI 1.06 - 2.4), respectively. Persistent objective vision loss at 4 months post-RT was the most important symptom type in predicting salvage decompression. Chronic dry eye occurred in 9 patients (9.9%) and cataracts developed in 4 patients (4.4%). RT is effective and well tolerated as initial local therapy for active GO, with only 21% of patients requiring decompressive surgery post RT. Most patients experience stabilization or improvement of GO symptoms, but moderate to significant response occurs in the minority of patients. Smoking status and total symptom severity at 4 months, primarily persistent objective vision loss, are the primary determinants of the need for post-RT salvage bony decompression. Patients who smoke or present with predominantly vision loss symptoms should be advised as to their lower likelihood of symptomatic response to RT and their increased likelihood of requiring post-RT decompressive surgery.

Software for pre-processing Illumina next-generation sequencing short read sequences

PubMed Central

2014-01-01

Background When compared to Sanger sequencing technology, next-generation sequencing (NGS) technologies are hindered by shorter sequence read length, higher base-call error rate, non-uniform coverage, and platform-specific sequencing artifacts. These characteristics lower the quality of their downstream analyses, e.g. de novo and reference-based assembly, by introducing sequencing artifacts and errors that may contribute to incorrect interpretation of data. Although many tools have been developed for quality control and pre-processing of NGS data, none of them provide flexible and comprehensive trimming options in conjunction with parallel processing to expedite pre-processing of large NGS datasets. Methods We developed ngsShoRT (next-generation sequencing Short Reads Trimmer), a flexible and comprehensive open-source software package written in Perl that provides a set of algorithms commonly used for pre-processing NGS short read sequences. We compared the features and performance of ngsShoRT with existing tools: CutAdapt, NGS QC Toolkit and Trimmomatic. We also compared the effects of using pre-processed short read sequences generated by different algorithms on de novo and reference-based assembly for three different genomes: Caenorhabditis elegans, Saccharomyces cerevisiae S288c, and Escherichia coli O157 H7. Results Several combinations of ngsShoRT algorithms were tested on publicly available Illumina GA II, HiSeq 2000, and MiSeq eukaryotic and bacteria genomic short read sequences with the focus on removing sequencing artifacts and low-quality reads and/or bases. Our results show that across three organisms and three sequencing platforms, trimming improved the mean quality scores of trimmed sequences. Using trimmed sequences for de novo and reference-based assembly improved assembly quality as well as assembler performance. In general, ngsShoRT outperformed comparable trimming tools in terms of trimming speed and improvement of de novo and reference-based assembly as measured by assembly contiguity and correctness. Conclusions Trimming of short read sequences can improve the quality of de novo and reference-based assembly and assembler performance. The parallel processing capability of ngsShoRT reduces trimming time and improves the memory efficiency when dealing with large datasets. We recommend combining sequencing artifacts removal, and quality score based read filtering and base trimming as the most consistent method for improving sequence quality and downstream assemblies. ngsShoRT source code, user guide and tutorial are available at http://research.bioinformatics.udel.edu/genomics/ngsShoRT/. ngsShoRT can be incorporated as a pre-processing step in genome and transcriptome assembly projects.

Streptococcus mutans and Streptococcus sobrinus are closely associated with the development of early childhood caries (ECC). Recently, quantitative real-time polymerase chain reaction (qRT-PCR) has been used for rapid and accurate quantification of these bacterial species. This study aims to detect quantitatively the levels of S. mutans and S. sobrinus in plaque samples by qRT-PCR, and to assess their association with the prevalence of ECC in Korean preschool children. One hundred and five children (71 months old or younger) were examined and classified into three groups (caries-free, ECC, severe ECC). Dental plaque samples were collected and qRT-PCR was conducted using oligonucleotide primers specific for glucosyltransferase gene (S. mutans-gtfB, S. sobrinus-gtfU) and universal primer. Pearson's correlation test was conducted to evaluate the relationship between the dmfs (decayed, missing, or filled surfaces primary teeth) scores and the microbiological findings. There was a significant difference between the levels of S. mutans and S. sobrinus in the plaque samples of the three groups (P < 0.05). The proportion of S. sobrinus to S. mutans showed strong correlation to the dmfs scores (r = 0.748, P < 0.05). The qRT-PCR results of this study showed that children with ECC had higher level of S. mutans and S. sobrinus in their dental plaque samples. The children with higher ratio of S. sobrinus to S. mutans in their dental plaque showed higher incidence of ECC.

There is a strong correlation between neurocognition and social cognition. However, none of these studies have examined the key role of time consumption during social cognition tasks. Participants included 84 individuals with clinical high risk of psychosis (CHR), 95 healthy controls (HC), and 66 case controls (schizophrenia patients, SZ), who were assessed through the Reading-Mind-in-Eyes Tasks (RMET) with computerized recording of the response time (RT). Neurocognitive tests were also performed for the HC and CHR groups. A comparison of RMET performance revealed significantly lower scores in the SZ group compared to the HC group, with CHR individuals scoring between these two. However, both CHR and SZ subjects spent almost twice as long of the time on RMET compared to the HC subjects. Significant positive correlation was found between RMET accuracy and RT, though only in SZ patients. Taking the RT into consideration, the RMET performances were impacted by different neurocognition domains. Our findings provide new evidence about how time consumption in mind-reading may impact the relationship between social cognition and neurocognition, and we discuss the potential importance of recording the response time during social cognition assessment in individuals with early psychosis.

Given the adverse consequences of psychiatric and psychosocial morbidity on the quality of life for patients with cancer, prompt detection of psychological symptoms is mandatory. The authors examined the properties and accuracy of the Brief Symptom Inventory (the 53-item version [BSI] and the 18-item version [BSI-18]) for the detection of psychiatric morbidity compared with the World Health Organization Composite International Diagnostic Interview (CIDI) for International Classification of Diseases-10th Revision psychiatric diagnoses. A convenience sample of 498 patients with newly diagnosed cancer who were recruited in cancer outpatient services participated in the CIDI interview and in BSI and BSI-18 assessments. The prevalence of psychiatric morbidity was 39.75%. When participants were classified as cases using the BSI standard case rule, agreement with the CIDI was potentially acceptable (sensitivity, 72.7%; specificity, 88.7%). In contrast, the accuracy of the BSI-18 in identifying cases was poor according to the standard case rule, with very low sensitivity (29.3%) (misclassification rate, 28.7%). By using a first alternative case-rule system (a BSI-18 global severity index [GSI] T-score ≥57), sensitivity marginally improved (45%), whereas a second alternative case-rule system (a GSI T-score ≥50) significantly increased sensitivity (77.3%). In receiver operating characteristic curve analysis, a further cutoff GSI T-score ≥48 exhibited good discrimination levels (sensitivity, 82.3%; specificity, 72.4%). There were some differences in GSI cutoff T-scores according to the International Classification of Diseases-10th Revision diagnosis and sex. The BSI appeared to have acceptable diagnostic accuracy compared with a standardized psychiatric interview. For the BSI-18, it is mandatory to use alternative case-rule systems, to identify patients with psychiatric morbidity.

Self-poisoning with organophosphorus (OP) compounds is a major cause of morbidity and mortality across South Asian countries. To develop uniform and effective management guidelines, the severity of acute OP poisoning should be assessed through scientific methods and a clinical database should be maintained. A prospective descriptive survey was carried out to assess the utility of severity scales in predicting the outcome of 71 organophosphate (OP) and carbamate poisoning patients admitted during a one year period at the Kasturba Hospital, Manipal, India. The Glasgow coma scale (GCS) scores, acute physiology and chronic health evaluation II (APACHE II) scores, predicted mortality rate (PMR) and Poisoning severity score (PSS) were estimated within 24h of admission. Significant correlation (P<0.05) between PSS and GCS and APACHE II and PMR scores were observed with the PSS scores predicting mortality significantly (P< or =0.001). A total of 84.5% patients improved after treatment while 8.5% of the patients were discharged with severe morbidity. The mortality rate was 7.0%. Suicidal poisoning was observed to be the major cause (80.2%), while other reasons attributed were occupational (9.1%), accidental (6.6%), homicidal (1.6%) and unknown (2.5%) reasons. This study highlights the application of clinical indices like GCS, APACHE, PMR and severity scores in predicting mortality and may be considered for planning standard treatment guidelines.

This present study estimated the psychiatric morbidity among informal caregivers of older adults and investigated its association with their socio-demographic factors and older adult's health status, including dementia, depression and physical health conditions. Data from a national cross-sectional survey were used. For each participating older adult, an informal caregiver who 'knew the older adult best' and was aware of their health condition, was also interviewed to collect information on the older adults' care needs, and behavioral and psychological symptoms of dementia (BPSD). Data from 693 pairs was used. Informal caregivers were administered the Self Reporting Questionnaire (SRQ)-20 and psychiatric morbidity was defined as those with a total SRQ score of ≥8. Measures included informal caregivers' socio-demographic characteristics, assessment of dementia and depression in the older adults and self-report on their lifetime and current physical conditions. The association of socio-demographic characteristics, health conditions, care assistance and BPSD was investigated using backward stepwise logistic regression analysis where psychiatric morbidity (total SRQ score

This study aimed to evaluate posttreatment soft-tissue changes in patients with oral cancer with computed tomography (CT). To accomplish that purpose, a scoring system was established, referring to the criteria of lower leg lymphedema (LE). One hundred and six necks in 95 patients who underwent oral oncologic surgery with neck dissection (ND) were analyzed retrospectively using routine follow-up CT images. A two-point scoring system to evaluate soft-tissue changes (so-called "LE score") was established as follows: Necks with a "honeycombing" appearance were assigned 1 point. Necks with "taller than wide" fat lobules were assigned 1 point. Necks with neither appearance were assigned 0 points. Comparisons between patients with LE score ≥1 and LE score = 0 at 6 months postoperatively were performed using the Fisher exact test for discrete variables and the Mann-Whitney U test for continuous variables. Univariate predictors associated with posttreatment changes (i.e., LE score ≥1 at 6 months postoperatively) were entered into a multivariate logistic regression analysis. Values of p < 0.05 were considered to indicate statistical significance. The occurrence of the posttreatment soft-tissue changes was 32%. Multivariate logistic regression analysis showed that postoperative radiation therapy (RT) and bilateral ND were potential risk factors of posttreatment soft-tissue changes on CT images. Sequential evaluation of "honeycombing" and the "taller than wide" appearances on routine follow-up CT revealed the persistence of posttreatment soft-tissue changes in patients who underwent oral cancer treatment, and those potential risk factors were postoperative RT and bilateral ND.

Genetic selection for body temperature during heat stress might be a useful approach to reduce the magnitude of heat stress effects on production and reproduction. Objectives of the study were to estimate the genetic parameters of rectal temperature (RT) in dairy cows in freestall barns under heat stress conditions and to determine the genetic and phenotypic correlations of rectal temperature with other traits. Afternoon RT were measured in a total of 1,695 lactating Holstein cows sired by 509 bulls during the summer in North Florida. Genetic parameters were estimated with Gibbs sampling, and best linear unbiased predictions of breeding values were predicted using an animal model. The heritability of RT was estimated to be 0.17 ± 0.13. Predicted transmitting abilities for rectal temperature changed 0.0068 ± 0.0020°C/yr from (birth year) 2002 to 2008. Approximate genetic correlations between RT and 305-d milk, fat, and protein yields, productive life, and net merit were significant and positive, whereas approximate genetic correlations between RT and somatic cell count score and daughter pregnancy rate were significant and negative. Rectal temperature during heat stress has moderate heritability, but genetic correlations with economically important traits mean that selection for RT could lead to lower productivity unless methods are used to identify genes affecting RT that do not adversely affect other traits of economic importance.

It is not known the relationships between a difference in systolic blood pressure (SBP) or diastolic BP (DBP) between arms by synchronal measurement and the presence of coronary artery disease (CAD), and between a difference in BP between arms and the severity of coronary atherosclerosis. We enrolled 425 consecutive patients (M/F = 286/139, 67 ± 13 year) who were admitted to our University Hospital and in whom we could measure the absolute (|rt. BP - lt. BP|) and relative (rt. BP - lt. BP) differences in SBP and DBP using a nico PS-501(®) (Parama-Tech). We divided all patients into those who did and did not have CAD. The relative differences in SBP between arms in patients with CAD were significantly lower than those in patients without CAD. However, the relative difference in SBP between arms was not a predictor of the presence of CAD. We also divided 267 patients who underwent coronary angiography into tertiles according to the Gensini score (low, middle, and high score groups). Interestingly, the middle + high score groups showed significantly lower relative differences in SBP between arms than the low score group. The mean Korotkoff sound graph in the middle + high Gensini score group was significantly higher than that in the low Gensini score group. Among conventional cardiovascular risk factors and nico parameters, the relative difference in SBP between arms in addition to the risk factors (age, gender, body mass index, hypertension, dyslipidemia, and diabetes mellitus) was associated with the score by a logistic regression analysis. In conclusion, the relative difference in SBP between arms as well as conventional risk factors may be associated with the severity of coronary arteriosclerosis.

Obese and morbidly obese patients undergoing lumbar spinal fusion surgery are a challenge to the operating surgeon. Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and open-TLIF have been performed for many years with good results; however, functional outcomes after lumbar spine surgery in this subgroup of patients remain poorly understood. Furthermore, whether index MIS-TLIF or open-TLIF for the treatment of degenerative disc disease or spondylolisthesis in morbidly obese results in superior postoperative functional outcomes remains unknown. A total of 148 (MIS-TLIF: n = 40, open-TLIF: n = 108) obese and morbidly obese patients undergoing index lumbar arthrodesis for low back pain and/or radiculopathy between January 2003 and December 2010 were selected from a multi-institutional prospective data registry. We collected and analyzed data on patient demographics, postoperative complications, back pain, leg pain, and functional disability over 2 years. Patients completed the Oswestry Disability Index (ODI), Medical Outcomes Study Short-Form 36 (SF-36), and back and leg pain numerical rating scores before surgery and then at 12 and 24 months after surgery. Clinical outcomes and complication rates were compared between both patient cohorts. Compared with preoperative status, Visual Analog Scale (VAS) back and leg pain, ODI, and SF-36 physical component score/mental component score were improved in both groups. Both MIS-TLIF and open-TLIF patients showed similar 2-year improvement in VAS for back pain (MIS-TLIF: 2.42 ± 3.81 vs. open-TLIF: 2.33 ± 3.67, P = 0.89), VAS for leg pain (MIS-TLIF: 3.77 ± 4.53 vs. open-TLIF: 2.67 ± 4.10, P = 0.18), ODI (MIS-TLIF: 11.61 ± 25.52 vs. open-TLIF: 14.88 ± 22.07, P = 0.47), and SF-36 physical component score (MIS-TLIF: 8.61 ± 17.72 vs. open-TLIF: 7.61 ± 15.55, P = 0.93), and SF-36 mental component score (MIS-TLIF: 4.35 ± 22.71 vs. open-TLIF: 5.96 ± 21.09, P = 0.69). Postoperative complications rates between both cohorts were also not significantly divergent between (12.50% vs. 11.11%, P = 0.51). MIS-TLIF is a safe and viable option for lumbar fusion in morbidly obese patients and, compared with open-TLIF, resulted in similar improvement in pain and functional disability. Postoperative complications rates between both cohorts were also not significantly divergent. Copyright © 2015 Elsevier Inc. All rights reserved.

Dopamine agonists can impair inhibitory control and cause impulse control disorders for those with Parkinson disease (PD), although mechanistically this is not well understood. In this study, we hypothesized that the extent of such drug effects on impulse control is related to specific dopamine gene polymorphisms. This double-blind, placebo-controlled study aimed to examine the effect of single doses of 0.5 and 1.0 mg of the dopamine agonist ropinirole on impulse control in healthy adults of typical age for PD onset. Impulse control was measured by stop signal RT on a response inhibition task and by an index of impulsive decision-making on the Balloon Analogue Risk Task. A dopamine genetic risk score quantified basal dopamine neurotransmission from the influence of five genes: catechol-O-methyltransferase, dopamine transporter, and those encoding receptors D1, D2, and D3. With placebo, impulse control was better for the high versus low genetic risk score groups. Ropinirole modulated impulse control in a manner dependent on genetic risk score. For the lower score group, both doses improved response inhibition (decreased stop signal RT) whereas the lower dose reduced impulsiveness in decision-making. Conversely, the higher score group showed a trend for worsened response inhibition on the lower dose whereas both doses increased impulsiveness in decision-making. The implications of the present findings are that genotyping can be used to predict impulse control and whether it will improve or worsen with the administration of dopamine agonists.

We examined the association of cardiovascular health at younger ages with the proportion of life lived free of morbidity, the cumulative burden of morbidity, and average healthcare costs at older ages. The CHA study (Chicago Heart Association Detection Project in Industry) is a longitudinal cohort of employed men and women 18 to 74 years of age at baseline examination in 1967 to 1973. Baseline measurements included blood pressure, cholesterol, diabetes mellitus, body mass index, and smoking. Individuals were classified into 1 of 4 strata of cardiovascular health: favorable levels of all factors, 0 factors high but ≥1 elevated risk factors, 1 high risk factor, and ≥2 high risk factors. Linked Medicare and National Death Index data from 1984 to 2010 were used to determine morbidity in older age. An individual's all-cause morbidity score and cardiovascular morbidity score were calculated from International Classification of Disease, Ninth Revision codes for each year of follow-up. We included 25 804 participants who became ≥65 years of age by 2010, representing 65% of all original CHA participants (43% female; 90% white; mean age, 44 years at baseline); 6% had favorable levels of all factors, 19% had ≥1 risk factors at elevated levels, 40% had 1 high risk factor, and 35% had ≥2 high risk factors. Favorable cardiovascular health at younger ages extended survival by almost 4 years and postponed the onset of all-cause and cardiovascular morbidity by 4.5 and 7 years, respectively, resulting in compression of morbidity in both absolute and relative terms. This translated to lower cumulative and annual healthcare costs for those in favorable cardiovascular health ( P <0.001) during Medicare eligibility. Individuals in favorable cardiovascular health in early middle age live a longer, healthier life free of all types of morbidity. These findings provide strong support for prevention efforts earlier in life aimed at preserving cardiovascular health and reducing the burden of disease in older ages. © 2017 American Heart Association, Inc.

Bilateral axillo-breast approach (BABA) robotic thyroidectomy (RT) is proven to be a feasible method for the treatment of well-differentiated thyroid cancers in terms of oncology as well as cosmesis. However, BABA RT causes postoperative sternal discomfort and needs an incision over the nipple areolar area. Here, we suggest a novel robotic surgical technique for thyroid surgery that does not need a breast incision-bilateral axillary approach (BAA). We recruited 51 patients who were willing to undergo the novel BAA robotic thyroid surgery. We performed a propensity score-matched analysis to compare the BAA robotic thyroid surgery group (BAA group) with the conventional open thyroid surgery group (open group). Mean operation time in the BAA group (129.7 min) was significantly longer than that in the open group (103.1 min) (p < 0.001). However, no significant differences in the mean number of metastatic lymph nodes (LNs), mean number of retrieved LNs, vocal cord palsy, hypoparathyroidism, and mean stimulated thyroglobulin level were observed between the two groups. There was no case of postoperative bleeding or chyle leak. Of the 51 patients who had undergone the BAA procedure, 27 patients answered the questionnaire. The mean scale, ranging from 0 to 10, at postoperative 1 day/2 weeks was as follows: voice change score, 3.0/1.6; swallowing difficulty score, 4.0/2.0; anterior neck pain score, 4.6/3.6; anterior neck numbness score, 5.4/4.3; right chest pain score, 3.8/2.1; left chest pain score, 3.6/2.3; right chest numbness score, 3.2/2.8; left chest numbness score, 2.4/2.7; right breast pain score, 0.9/0; left breast pain score, 1.2/0; right breast numbness score, 1.7/0; and left breast numbness score, 2.6/0, respectively. BAA robotic thyroid surgery is a novel, safe, and feasible oncoplastic method, especially for patients who have fear of procedures around the nipple areolar complex.

Listening Effort Through Depth of Processing in School-Age Children.

PubMed

Hsu, Benson Cheng-Lin; Vanpoucke, Filiep; van Wieringen, Astrid

A reliable and practical measure of listening effort is crucial in the aural rehabilitation of children with communication disorders. In this article, we propose a novel behavioral paradigm designed to measure listening effort in school-age children based on different depths and levels of verbal processing. The paradigm consists of a classic word recognition task performed in quiet and in noise coupled to one of three additional tasks asking the children to judge the color of simple pictures or a certain semantic category of the presented words. The response time (RT) from the categorization tasks is considered the primary indicator of listening effort. The listening effort paradigm was evaluated in a group of 31 normal-hearing, normal-developing children 7 to 12 years of age. A total of 146 Dutch nouns were selected for the experiment after surveying 14 local Dutch-speaking children. Windows-based custom software was developed to administer the behavioral paradigm from a conventional laptop computer. A separate touch screen was used as a response interface to gather the RT data from the participants. Verbal repetition of each presented word was scored by the tester and a percentage-correct word recognition score (WRS) was calculated for each condition. Randomized lists of target words were presented in one of three signal to noise ratios (SNR) to examine the effect of background noise on the two outcome measures of WRS and RT. Three novel categorization tasks, each corresponding to a different depth or elaboration level of semantic processing, were developed to examine the effect of processing level on either WRS or RT. It was hypothesized that, while listening effort as measured by RT would be affected by both noise and processing level, WRS performance would be affected by changes in noise level only. The RT measure was also hypothesized to increase more from an increase in noise level in categorization conditions demanding a deeper or more elaborate form of semantic processing. There was a significant effect of SNR level on school-age children's WRS: their word recognition performance tended to decrease with increasing background noise level. However, depth of processing did not seem to affect WRS. Moreover, a repeated-measure analysis of variance fitted to transformed RT data revealed that this measure of listening effort in normal-hearing school-age children was significantly affected by both SNR level and the depth of semantic processing. There was no significant interaction between noise level and the type of categorization task with regard to RT. The observed patterns of WRS and RT supported the hypotheses regarding the effects of background noise and depth of processing on word recognition performance and a behavioral measure of listening effort. The magnitude of noise-induced change in RT did not differ between categorization tasks, however. Our findings point to future research directions regarding the potential effects of age, working memory capacity, and cross-modality interaction when measuring listening effort in different levels of semantic processing.

Obesity leads to olfaction alterations, and this can further impact food choices, appetite, and nutritional status. Bariatric procedures induce weight loss and change in taste and smell perception, but more information is needed, especially using objective olfaction tests. A prospective study was conducted during 6 months, with candidates to laparoscopic gastric bypass at a single institution. A preoperative nasofibroscopy and gross smell identification test (The Pocket Smell Test ®) were performed in those meeting the inclusion criteria. After 6 months, a new test was performed, and the primary objective was to determine if there was an improvement in the olfaction score. Weight loss and comorbidities improvement were also analyzed. From the 30 patients with morbid obesity enrolled, 21 met the inclusion criteria and ENT evaluation. At baseline, 42.8% of patients scored 3 points, 53.3% scored 2 points, and 4.7% scored 1 point. After 6 months, there was a -81.1% of change. Seventeen patients scored 3 points (p = 0.002 vs initial) and two scored 2 points (p = 0.006 vs initial). There were no patients with less than 2 points. Weight and comorbidities had a significant improvement as well. Laparoscopic gastric bypass improves the olfaction scores of the Pocket Smell Test in morbidly obese patients 6 months after their procedure. More complex tests can be used in candidates to bariatric surgery if low scores are detected initially. Other causes of olfaction dysfunctions should be determined if there is no improvement after weight loss.

While there is growing evidence for positive effects of progressive resistance training in curatively treated cancer patients, data on advanced cancer patients are scarce. This pilot study aimed at investigating for the first time feasibility and effects of progressive resistance training in advanced cancer patients undergoing tyrosine kinase inhibitor (TKI) therapy. Patients starting a TKI-based anti-tumor therapy were assigned to a resistance training group (RT, 12 weeks of progressive machine-based resistance training 2×/week) or a control group (CON, treatment as usual) until 10 patients had finished in each group (RT 80% males, 90% renal cell carcinoma, 65 ± 11 years, CON 80% males, 70% renal cell carcinoma, 61 ± 6 years). Primary endpoint was feasibility. Furthermore, fatigue (MFI), quality of life (QoL, EORTC QLQC30), and muscle strength were assessed. Testing occurred at baseline and after 12 weeks. Training was feasible in 9 out of 10 participants and no serious adverse events occurred. It had beneficial effects on muscle strength (maximum voluntary isometric contraction of the quadriceps: RT +11 ± 9 Nm, CON -13 ± 25 Nm, p = 0.005), but not on fatigue (general fatigue score RT +0.3 ± 4.1, CON -1.5 ± 3.0, p = 0.223) or QoL (global QoL score RT -5.6 ± 16.1, CON -2.0 ± 18.2, p = 0.617). Progressive machine-based resistance training appears feasible in the majority of advanced cancer patients undergoing TKI therapy. However, its positive effects on muscle strength do not seem to be associated with positive effects on fatigue or quality of life. Future studies should therefore compare whether home-based training is more beneficial for patient-reported outcomes. NCT01645150.

To test the ability of a reverse transcriptase-PCR (RT-PCR) assay, based on gene expression profiles, to accurately determine the risk of recurrence in patients with node-negative breast cancer who did not receive systemic therapy using formalin-fixed, paraffin-embedded tissue. A secondary objective was to determine whether the quantitative RT-PCR data correlated with immunohistochemistry assay data regarding estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status. We obtained archival paraffin-embedded tissue from patients with invasive breast cancer but no axillary lymph node involvement who had received no adjuvant systemic therapy and been followed for at least 5 years. RNA was extracted from three 10-microm-thick sections. The expression of 16 cancer-related genes and 5 reference genes was quantified using RT-PCR. A gene expression algorithm was used to calculate a recurrence score for each patient. We then assessed the ability of the test to accurately predict distant recurrence-free survival in this population. We identified 149 eligible patients. Median age at diagnosis was 59 years; mean tumor diameter was 2 cm; and 69% of tumors were estrogen receptor positive. Median follow-up was 18 years. The 5-year disease-free survival rate for the group was 80%. The 21 gene-based recurrence score was not predictive of distant disease recurrence. However, a high concordance between RT-PCR and immunohistochemical assays for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status was noted. RT-PCR can be done on paraffin-embedded tissue to validate the large numbers of genes associated with breast cancer recurrence. However, further work needs to be done to develop an assay to identify the likelihood of recurrent disease in patients with node-negative breast cancer who do not receive adjuvant tamoxifen or chemotherapy.

The likelihood of distant recurrence in patients with breast cancer who have no involved lymph nodes and estrogen-receptor-positive tumors is poorly defined by clinical and histopathological measures. We tested whether the results of a reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of 21 prospectively selected genes in paraffin-embedded tumor tissue would correlate with the likelihood of distant recurrence in patients with node-negative, tamoxifen-treated breast cancer who were enrolled in the National Surgical Adjuvant Breast and Bowel Project clinical trial B-14. The levels of expression of 16 cancer-related genes and 5 reference genes were used in a prospectively defined algorithm to calculate a recurrence score and to determine a risk group (low, intermediate, or high) for each patient. Adequate RT-PCR profiles were obtained in 668 of 675 tumor blocks. The proportions of patients categorized as having a low, intermediate, or high risk by the RT-PCR assay were 51, 22, and 27 percent, respectively. The Kaplan-Meier estimates of the rates of distant recurrence at 10 years in the low-risk, intermediate-risk, and high-risk groups were 6.8 percent (95 percent confidence interval, 4.0 to 9.6), 14.3 percent (95 percent confidence interval, 8.3 to 20.3), and 30.5 percent (95 percent confidence interval, 23.6 to 37.4). The rate in the low-risk group was significantly lower than that in the high-risk group (P<0.001). In a multivariate Cox model, the recurrence score provided significant predictive power that was independent of age and tumor size (P<0.001). The recurrence score was also predictive of overall survival (P<0.001) and could be used as a continuous function to predict distant recurrence in individual patients. The recurrence score has been validated as quantifying the likelihood of distant recurrence in tamoxifen-treated patients with node-negative, estrogen-receptor-positive breast cancer.

Gastrointestinal (GI) symptoms pose a significant burden to patients receiving chemoradiation therapy (CRT) for anal cancer; however, the impact of symptoms from the patient perspective has not been quantified. This retrospective study examined and compared patient and clinician reports of acute GI toxicity during CRT. Patients treated with definitive RT using intensity-modulated radiation therapy for anal cancer between 9/09 and 11/12 were reviewed. Median RT dose was 56 Gy (range 45-56), and 76 patients (97%) received concurrent 5-fluorouracil-based chemotherapy. During RT, patients completed the 7-item Bowel Problem Scale (BPS) weekly. Clinicians assessed toxicity separately using CTCAE v. 3.0. Scores of BPS ≥ 3 and CTCAE ≥ 1 were considered to be clinically meaningful. Agreement of the two assessments was evaluated by Cohen's kappa coefficient. Seventy-eight patients completed at least one BPS and had a corresponding clinician assessment. Patients reporting scores of ≥3 was highest at week 5 (n = 68) for diarrhea (44.1%), proctitis (57.4%), and mucus (48.4%), while urgency (47.6%), tenesmus (31.7%), and cramping (27%) were highest at week 4 (n = 63). Baseline bleeding scores (26.7%; score ≥3) improved during treatment (13.4% at week 5). "Poor" agreement was observed between patient- and clinician-reported proctitis (Cohen's k = 0.11; n = 58); however, there was "good" agreement for diarrhea (Cohen's k = 0.68; n = 58). Acute GI toxicity during definitive CRT for anal cancer was most significant during weeks 4-5, while rectal bleeding improved during treatment. Discrepancies in patient- and clinician-reported symptoms demonstrate the potential for patient-reported outcomes to be useful tools for anal cancer clinical assessments.

To assess the main neonatal morbidity results in relation to induced labour indications. Historical groups from a total of 3,817 deliveries over a three year period (2009, 2010 and 2011) in "Mancha-Centro" Hospital (Alcázar de San Juan) formed the study group. All programmed and non-avoidable caesarean sections and pregnancies under 35 weeks were excluded. The main variable result was a neonatal morbidity variable made up of the Apgar score after 5 min, pH of umbilical artery <7.10 and the neonatal need for resuscitation type III-V. Multivariate analysis was used to control confounding variables. The incidence of induced labour was 22.6 % (862). The highest indication was premature rupture of membranes for more than 12 h 22.8 % (190), poorly controlled diabetes 22.6 % (189) and oligoamnios 16.2 % (135). The rate of pH lower than 7.10 was 2.8 % (22), the rate of the Apgar score lower than 7 after 5 min was 0.2 % (2) and the neonatal need for resuscitation type III-IV was 5.7 % (48) for induced labour. The relation between induced labour and neonatal morbidity indicators were not statistically significant. 10.1 % (4) of induced labour for suspected intrauterine growth restriction and 8.6 % (10) of postterm pregnancies required neonatal resuscitation type III-IV. No relation was found between induced labour and the neonatal morbidity indicators. The highest neonatal risk indicator is when a intrauterine growth restriction, hypertensión/preeclampsia or a postterm pregnancy is suspected.

Research about personality factors involved in successful outcome after bariatric surgery has led to contrasting results. The reasons for such discrepancies may include the lack of assessment of adaptive personality traits and of psychiatric co-morbidity, which may limit the reliability of personality findings. This study aimed to provide exploratory data regarding preoperative personality dimensions and weight loss prediction 1 year after laparoscopic adjustable gastric banding (LAGB). Both normal and deviant personality patterns were assessed by means of the Temperament and Character Inventory (TCI). Moreover, co-morbid psychiatric disturbances were evaluated both categorically and dimensionally. 65 morbidly obese subjects applying for LAGB were evaluated preoperatively by means of the TCI, standardized diagnostic interview, rating scales and questionnaires to assess co-morbid psychopathology. After intake screening, 35 subjects (mean age 41.2, mean BMI 45.5) were accepted for and underwent LAGB. BMI reduction 1 year following LAGB was used as an outcome measure and entered as a dependent variable in a stepwise multiple regression analysis. TCI scores, presence and severity of eating, depressive and anxiety disorders, sex, age, level of education and BMI at baseline were tested as independent variables. Preoperative TCI 'Persistence' scores explained >40% of variance of BMI reduction 1 year following LAGB, irrespective of preoperative BMI, age, gender, educational level, psychiatric co-morbidity, psychopathology severity and other temperament and character features. Some personality dimensions, as measured by the TCI, may be involved in successful weight control after LAGB.

Background: Majority of the health problems affecting school children are preventable by promotion of hygienic practices through proper health education by the teachers, who are the first contacts. Objectives: The study was undertaken to find out the status of nutrition and personal hygiene among primary school children and their association with their varied morbidity profiles. Materials and Methods: A descriptive, observational, cross-sectional study was conducted in a primary school situated in the largest slum of Kolkata. Results: The participants included 103 boys and 81 girls, with a mean age of 6.2 years. The mean personal hygiene score of the girls (4.15 ± 0.98) was significantly higher than that of boys (3.2 ± 1.4) [P<0.05]. Most of the boys (54.37%) and girls (74.07%) were normally nourished as per the CDC growth chart. Over 70% of the children were suffering from one or more morbidities, the most common morbidity in both the sexes being pallor, followed by worm infestation. Personal hygiene scores were significantly higher (P<0.05) among those children who were normally nourished as well as those who did not suffer from any morbidity in the last 15 days. Conclusions: Care should be taken to improve the pitiable state of personal hygiene and poor sanitary practices of these school children through coordinated and concerted health education measures by teachers as well as parents.

The purpose of this study was to examine the association of smoking and nicotine dependence with psychiatric morbidity, controlling for the potential confounding effect of smoking on the relationship between the use of other substances and psychiatric morbidity. A sample of 290 adults were interviewed at a primary health centre (patients, 58%; patients' relatives, 34%; staff, 8%) to inquire about their tobacco, caffeine, alcohol, and illegal drug consumption. Psychiatric morbidity, defined by a score >6 on the General Health Questionnaire (GHQ-28), showed a strong direct association with nicotine dependence. The use of illegal drugs, but not of alcohol, was also strongly associated with psychiatric morbidity, after controlling for smoking. Both smoking and high nicotine dependence were also associated with use of caffeine, alcohol, cannabis and cocaine. High nicotine dependence may be considered as an expression of individual psychopathologic vulnerability. Tobacco may have a central facilitating role in the use of caffeine, alcohol, and illegal drug.

To determine which specific groups of occupational stress factors influence the duration of temporary work disability related to arterial hypertension and joint complications/co-morbidities. Workers (n = 1398; 1009 in the exposed group, 389 in the control group) with arterial hypertension who worked at one workplace for a minimum of 10 years were divided into 10 subgroups, depending on the presence of joint complications/co-morbidities. The intensity of seven groups of occupational stress factors, the total score of Occupational Stress Index (OSI) and the average number of lost working days during 1 year were analysed. The number of lost working days due to arterial hypertension and joint complications/co-morbidities was significantly higher in the exposed group. In all subgroups of the exposed group there was a high correlation between the number of lost working days and the total OSI score. Specific occupational stress factors were associated with specific complications: High Demands with chronic myocardial infarction, Strictness with cerebral haemorrhage, Conflict/Uncertainty with cerebral infarction, Extrinsic Time Pressure with acute myocardial infarction, and Avoidance/Symbolic Aversiveness with non-insulin-dependent diabetes. There are specific groups of occupational stress factors which can influence the duration of work disability associated with certain complications and co-morbidities of arterial hypertension.

A perforated peptic ulcer can be managed laparoscopically in selected patients. The purpose of this study was to evaluate whether conversion of emergency laparoscopy is inferior to primary median laparotomy in terms of postoperative morbidity and mortality. We analyzed patients who underwent laparoscopic or open surgery for a perforated peptic ulcer at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck between January, 1996 and December, 2010. Perforations were graded according to the Boey classification, a preoperative risk-scoring system. Conversion to laparotomy was necessary in 20 of the 45 patients who underwent laparoscopic surgery (CG); therefore, laparoscopic operations were completed in 25 patients (LG). The third patient cohort comprised 139 patients who underwent primary laparotomy (OG). Overall minor morbidity was significantly lower (p = 0.048) in the LG patients than in the OG patients, whereas no significant differences were found in major morbidity and mortality, particularly between the OG and CG. Patients' suitability for laparoscopic management should be decided on according to Boey's clinical scoring system. Our findings demonstrated that conversion from laparoscopy to laparotomy was not associated with elevated postoperative morbidity or mortality versus initial laparotomy. Therefore, emergency operations may be commenced laparoscopically in selected patients, especially considering the postoperative advantages of this approach.

Catheter-Directed Thrombolysis of Inferior Vena Cava Thrombosis in a 13-Day-Old Neonate and Review of Literature

Complete inferior vena cava thrombosis (IVC) in neonates is uncommon, but may cause significant morbidity. A 13-day-old neonate suffered IVC thrombosis secondary to antithrombin III deficiency, possibly contributed to by a mutation in the methyl tetrahydrofolate reductase gene. Catheter-directed thrombolysis (CDT) with recombinant tissue plasminogen activator (rt-PA, Alteplase) was used successfully to treat extensive venous thrombosis in this neonate without complications. We also review the literature on CDT for treatment of IVC thrombosis in critically ill neonates and infants.

Intravenous thrombolysis with recombinant tissue plasminogen activator (rtPA) improves the outcome for ischemic stroke patients who can be treated within 3 hours of symptom onset. The efficacy of thrombolysis has been demonstrated despite an increased risk of severe hemorrhagic transformation (HT) in patients treated with rtPA. We performed an analysis of risk factors for severe HT in the second European-Australasian Acute Stroke Study (ECASS II). HTs were classified by using clinical and radiological criteria as follows: hemorrhagic infarction (HI), parenchymal hemorrhage (PH), and symptomatic intracranial hemorrhage (SICH). Potential risk factors for HT were tested by stepwise logistic regression analysis, including rtPA-by-variable interactions. In addition, the distribution of bad outcome (modified Rankin score 5 to 6) at day 90 was stratified according to each category of HT. PH and SICH but not HI were associated with rtPA. Also, PH and SICH but not HI were more severe in rtPA-treated patients than in those receiving placebo. Risk factors for PH were rtPA, extent of parenchymal hypoattenuation on baseline CT, congestive heart failure, increasing age, and baseline systolic blood pressure. The risk of PH on rtPA was increased in older patients and in those who were treated with aspirin before thrombolysis. Risk factors for SICH were rtPA, congestive heart failure, extent of parenchymal hypoattenuation, and increasing age. The risk of SICH on rtPA was increased in patients who were treated with aspirin before thrombolysis. This secondary analysis of ECASS II has confirmed the importance of the extent of hypoattenuation as a risk factor for severe HT. The findings also suggest that older patients and those who have used aspirin before stroke are at higher risk of a severe HT on rtPA.

Prediction of DNA-binding residue is important for understanding the protein-DNA recognition mechanism. Many computational methods have been proposed for the prediction, but most of them do not consider the relationships of evolutionary information between residues. In this paper, we first propose a novel residue encoding method, referred to as the Position Specific Score Matrix (PSSM) Relation Transformation (PSSM-RT), to encode residues by utilizing the relationships of evolutionary information between residues. PDNA-62 and PDNA-224 are used to evaluate PSSM-RT and two existing PSSM encoding methods by five-fold cross-validation. Performance evaluations indicate that PSSM-RT is more effective than previous methods. This validates the point that the relationship of evolutionary information between residues is indeed useful in DNA-binding residue prediction. An ensemble learning classifier (EL_PSSM-RT) is also proposed by combining ensemble learning model and PSSM-RT to better handle the imbalance between binding and non-binding residues in datasets. EL_PSSM-RT is evaluated by five-fold cross-validation using PDNA-62 and PDNA-224 as well as two independent datasets TS-72 and TS-61. Performance comparisons with existing predictors on the four datasets demonstrate that EL_PSSM-RT is the best-performing method among all the predicting methods with improvement between 0.02-0.07 for MCC, 4.18-21.47% for ST and 0.013-0.131 for AUC. Furthermore, we analyze the importance of the pair-relationships extracted by PSSM-RT and the results validates the usefulness of PSSM-RT for encoding DNA-binding residues. We propose a novel prediction method for the prediction of DNA-binding residue with the inclusion of relationship of evolutionary information and ensemble learning. Performance evaluation shows that the relationship of evolutionary information between residues is indeed useful in DNA-binding residue prediction and ensemble learning can be used to address the data imbalance issue between binding and non-binding residues.

Prenatal High Risk Scoring: How Family Doctors Do It

PubMed Central

Shea, Philip

1978-01-01

Assessment of risk factors is an integral part of family medicine and of prenatal care. A strong positive relationship has been demonstrated between a high risk score and higher incidence of maternal or perinatal morbidity and mortality. The family physician, because of his previous knowledge of the patient, and his familiarity with a broad range of normals, is in a good position to use his clinical judgement in high risk scoring in pregnancy. We must also be cautious that high risk scoring does not become a self fulfilling prophecy. Risk scoring is simply risk scoring, not a plan of management and intervention. PMID:21301562

To study the psychosocial factors in patient with chronic hand eczema (CHE).
 Methods: Personality traits, emotional state, and quality of life of 240 patients with CHE and 221 normal control (NC) subjects were assessed by General Questionnaire, Eysenck Personality Questionnaire (EPQ), Self-Rating Depression Scale (SDS), Self-Rating Anxiety (SAS), and Eczema Quality of Life Scale (EQOLS).
 Results: In comparison, EPQ scores, scores of extraversion (E) factor in patients with CHE were significantly lower than those in NC subjects (P<0.01), but scores of neuroticism (N) factor in patients with CHE were significantly higher than those in NC subjects (P<0.01), while there was no significant difference in scores of psychoticism (P) and lie (L) factors between two groups (P>0.05). Patients with CHE had significantly higher scores in SDS and SAS compared with the NC subjects (P<0.01). Patients with CHE had significantly higher scores in scale of morbid, physical, social, psychological, general quality of life, and total scores of EQOLS compared with the NC subjects (P<0.01). The level of skin lesions and the degree of itch were significantly correlated with scores in scale SDS, SAS, morbid, physical, social, psychological, general quality of life, and total scores of EQOLS compared with the NC subjects (P<0.05).
 Conclusion: Personality of patients with CHE is prone to emotional instability of introverts.Patients with CHE have a higher level of depression and anxiety, and exert a negative effect on their quality of life, which is related to severity of disease.

OBJECTIVES Surgery for prosthetic valve endocarditis (PVE) is associated with significant morbidity and mortality as well as with increased resource utilization and costs. For risk and cost reduction, an understanding of contributing factors and interrelations is essential. METHODS Out of 1080 heart valve procedures performed between January 2010 and December 2012, 41 patients underwent surgery for PVE. Complete economic data were available for 30 of them (study cohort). The patients' mean age was 64 ± 12 years (range 37–79 years), and 73% were men. The clinical course was reviewed and morbidity, mortality and costs as well as associations between them were analysed. The cost matrix for each individual patient was obtained from the Institute for the Hospital Remuneration System (InEK GmbH, Germany). The median follow-up was 2.6 years [interquartile range (IQR) 3.7 years; 100% complete]. RESULTS Preoperative status was critical (EuroSCORE II >20%) in 43% of patients. Staphylococci were the most common infecting micro-organisms (27%). The operative mortality rate (≤30 days) was 17%. At 1 year, the overall survival rate was 71 ± 9%. At least one disease- or surgery-related complication affected 21 patients (early morbidity 70%), >1 complication affected 12 patients (40%). There was neither a recurrence of endocarditis, nor was a reoperation required. The mean total hospital costs were 42.6 ± 37.4 Thousand Euro (T€), median 25.7 T€, IQR 28.4 T€ and >100 T€ in 10% of cases. Intensive care unit/intermediate care (ICU/IMC) and operation accounted for 40.4 ± 18.6 and 25.7 ± 12.1% of costs, respectively. There was a significant correlation (Pearson's sample correlation coefficient) between total costs and duration of hospital stay (r = 0.83, P < 0.001) and between ICU/IMC costs and duration of ICU/IMC stay (r = 0.97, P < 0.001). The median daily hospital costs were 1.8 T€/day, but >2.4 T€/day in 25% of patients (upper quartile). The following pattern of associations was identified (P < 0.05). Early mortality was related to preoperative morbidity and postoperative renal failure. Early morbidity was associated with preoperative morbidity and urgency. Total costs were mainly explained by preoperative morbidity, postoperative morbidity and urgency. High EuroSCORE II, complex surgery, need for mechanical circulatory support as well as postoperative mortality and morbidity increased daily costs. CONCLUSIONS The timely diagnosis and treatment of these patients must be a priority, as preoperative morbidity is the major contributor towards mortality, morbidity and costs after surgery for PVE.

The purpose of this study is to describe the functional status of survivors from extracorporeal cardiopulmonary resuscitation instituted during in-hospital cardiac arrest using the Functional Status Scale. We aimed to determine risk factors leading to the development of new morbidity and unfavorable functional outcomes. This was a single-center retrospective chart review abstracting patient characteristics/demographic data, duration of cardiopulmonary resuscitation, duration of extracorporeal membrane oxygenation support, as well as maximum lactate levels within 2 hours before and after extracorporeal cardiopulmonary resuscitation. Cardiac arrest was defined as the administration of chest compressions for a nonperfusing cardiac rhythm. Extracorporeal cardiopulmonary resuscitation was defined by instituting extracorporeal membrane oxygenation during active chest compressions. Functional Status Scale scores were calculated at admission and on hospital discharge for patients who survived. Patients admitted in the pediatric cardiac ICU at C.S. Mott Children's Hospital from January 1, 2005, to December 31, 2015. Children less than 18 years who underwent extracorporeal cardiopulmonary resuscitation. Not applicable. Of 608 extracorporeal membrane oxygenation events during the study period, 80 were extracorporeal cardiopulmonary resuscitation (14%). There were 40 female patients (50%). Median age was 40 days (interquartile range, 9-342 d). Survival to hospital discharge was 48% (38/80). Median Functional Status Scale score at admission was 6 (interquartile range, 6-6) and at hospital discharge 9 (interquartile range, 8-11). Out of 38 survivors, 19 (50%) had a change of Functional Status Scale score greater than or equal to 3, that is consistent with new morbidity, and 26 (68%) had favorable functional outcomes with a change in Functional Status Scale score of less than 5. This is the first extracorporeal cardiopulmonary resuscitation report to examine changes in Functional Status Scale from admission (baseline) to discharge as a measure of overall functional outcome. Half of surviving patients (19/38) had new morbidity, while 68% (26/38) had favorable outcomes. Lactate levels, duration of cardiopulmonary resuscitation, and duration of extracorporeal membrane oxygenation were not found to be risk factors for the development of new morbidity and poor functional outcomes. Functional Status Scale may be used as a metric to monitor improvement of extracorporeal cardiopulmonary resuscitation outcomes and help guide research initiatives to decrease morbidity in this patient population.

Application of minimal access surgery in acute care surgery is limited due to various reasons. Laparoscopic omental patch repair (LOPR) for perforated peptic ulcer (PPU) surgery is safe and feasible but not widely implemented. We report our early experience of LOPR with emphasis on strict selection criteria. This is a descriptive study of all patients operated on for PPU at academic university-affiliated institutes from December 2010 to February 2012. All the patients who were operated on for LOPR were included as the study population and their records were studied. Perioperative outcomes, Boey score, Mannheim Peritonitis Index (MPI), and physiologic and operative severity scores for enumeration of mortality and morbidity (POSSUM) scores were calculated. All the data were tabulated in a Microsoft Excel spreadsheet and analyzed using Stata Version 8.x. (StataCorp, College Station, TX, USA). Fourteen patients had LOPR out of a total of 45 patients operated for the PPU. Mean age was 46 years (range 22-87 years). Twelve patients (86%) had a Boey score of 0 and all patients had MPI < 21 (mean MPI = 14). The predicted POSSUM morbidity and mortality were 36% and 7%, respectively. Mean ulcer size was 5 mm (range 2-10 mm), mean operating time was 100 minutes (range 70-123 minutes) and mean length of hospital stay was 4 days (range 3-6 days). There was no morbidity or mortality pertaining to LOPR. LOPR should be offered by acute care surgical teams when local expertise is available. This can optimize patient outcomes when strict selection criteria are applied.

Social outcomes and quality of life (QOL) of childhood cancer survivors (CCSs) remain unknown in Japan. We investigated these outcomes in young adult CCSs compared to those of their siblings in Japan, and analyzed the association between social outcome and SF-36 health survey subscale scores. Between 2007 and 2009, we performed a cross-sectional survey using self-rating questionnaires. We estimated social outcomes and health-related QOL by performing the SF-36 in each group: CCSs with or without stem cell transplantation (SCT)/radiotherapy (RT) and their siblings. Adjusted odds ratios for outcomes of interest were estimated using logistic regression analysis. Questionnaires from 185 CCSs and 72 CCS's siblings were analyzed. There were no differences in educational attainment or annual income. The SF-36 subscale scores of CCSs with SCT and RT were significantly lower than those of siblings in physical functioning (PF) (p < 0.001 and 0.003, respectively) and general health (GH) (both p = 0.001). Lower PF scores correlated with recurrence (p = 0.041) and late effects (p = 0.010), and poor GH scores with late effects (p = 0.006). The CCSs had made efforts to attain educational/vocational goals; however, a significant proportion of CCSs who had experienced late effects remain at increased risk of experiencing diminished QOL.

To develop a consensus on a set of key clinical outcomes for the evaluation of preventive interventions for preterm birth in asymptomatic pregnant women. A two-stage web-based Delphi survey and a face-to-face meeting of key stakeholders were used to develop a consensus on a set of critical and important outcomes. We approached five stakeholder groups (parents, midwives, obstetricians, neonatologists, and researchers) from middle- and high-income countries. Outcomes subjected to the Delphi survey were identified by systematic literature review and stakeholder input. Survey participants scored each outcome on a 9-point Likert scale anchored between 1 (limited importance) and 9 (critical importance). They had the opportunity to reflect on total and stakeholder subgroup feedback between survey stages. For consensus, defined a priori, outcomes required at least 70% of participants of each stakeholder group to score them as "critical" and less than 15% as "limited." A total of 228 participants from five stakeholder groups from three lower middle-income countries, seven upper middle-income countries, and 17 high-income countries were asked to score 31 outcomes. Of these participants, 195 completed the first survey and 174 the second. Consensus was reached on 13 core outcomes: four were related to pregnant women: maternal mortality, maternal infection or inflammation, prelabor rupture of membranes, and harm to mother from intervention. Nine were related to offspring: gestational age at birth, offspring mortality, birth weight, early neurodevelopmental morbidity, late neurodevelopmental morbidity, gastrointestinal morbidity, infection, respiratory morbidity, and harm to offspring from intervention. This core outcome set for studies that evaluate prevention of preterm birth developed with an international multidisciplinary perspective will ensure that data from trials that assess prevention of preterm birth can be compared and combined.

We investigated the effect of co-morbid bipolar disorder and bulimia on temperamental dimensions measured by TEMPS-A, relative to "pure" bulimia and "pure" bipolar disorder, in female patients. The study was performed on 47 patients with bipolar disorder (BD) with a mean age of 36±10 years, 96 patients with bulimia or bulimic type of anorexia, mean age 26±9 years and 50 control healthy females (HC), mean age 29±6 years. Among bulimic patients, a group of 68 subjects with co-morbid bulimia with bipolarity (BD+B) was identified, based on positive score of the Mood Disorder Questionnaire (MDQ). The TEMPS-A questionnaire, 110 questions version, has been used, evaluating five temperament domains: depressive, cyclothymic, hyperthymic, irritable and anxious. Parametric analysis was performed for 4 groups (BD, "pure" bulimia (PB), BD+B and HC), with 28 subjects randomly chosen from each group, using analysis of variance and cluster analysis. All clinical groups significantly differed from control group by having higher scores of depressive, cyclothymic, irritable and anxious temperaments and lower of hyperthymic one. Among patients, significantly higher scores of cyclothymic and irritable temperaments were found in BD+B compared to both PB and BD. These differences were also reflected in cluster analysis, where two clusters were identified. Bipolarity in bulimic patients assessed only by the MDQ. These results show that co-morbid bulimia and bipolar disorder is characterized by extreme dimensions of both cyclothymic and irritable temperaments, significantly higher than each single diagnosis. Possible clinical implications of such fact are discussed. Copyright © 2014 Elsevier B.V. All rights reserved.

Human immunodeficiency virus (HIV) and human cytomegalovirus (HCMV) coinfections have been shown to increase infant morbidity, mortality, and AIDS progression. In HIV-endemic regions, maternal HIV-exposed but HIV-uninfected infants, which is the majority of children affected by HIV, also show poor growth and increased morbidity. Although nutrition has been examined, the effects of HCMV infection have not been evaluated. We studied the effects of HCMV infection on the growth, development, and health of maternally HIV-exposed and unexposed infants in Zambia. Infants were examined in a cohort recruited to a trial of micronutrient-fortified complementary foods. HIV-infected mothers and infants had received perinatal antiretroviral therapy to prevent mother-to-child HIV transmission. Growth, development, and morbidity were analyzed by linear regression analyses in relation to maternal HIV exposure and HCMV infection, as screened by sera DNA for viremia at 6 months of age and by antibody for infection at 18 months. All HCMV-seropositive infants had decreased length-for-age by 18 months compared with seronegative infants (standard deviation [z]-score difference: -0.44 [95% confidence interval {CI}, -.72 to -.17]; P = .002). In HIV-exposed infants, those who were HCMV positive compared with those who were negative, also had reduced head size (mean z-score difference: -0.72 [95% CI, -1.23 to -.22]; P = .01) and lower psychomotor development (Bayley test score difference: -4.1 [95% CI, -7.8 to -.5]; P = .03). HIV-exposed, HCMV-viremic infants were more commonly referred for hospital treatment than HCMV-negative infants. The effects of HCMV were unaffected by micronutrient fortification. HCMV affects child growth, development, and morbidity of African infants, particularly in those maternally exposed to HIV. HCMV is therefore a risk factor for child health in this region.

To assess the prevalence of neurodevelopmental and psychiatric co-morbidities in children and adolescents diagnosed with attention-deficit hyperactivity disorder at a tertiary care child and adolescent psychiatry centre. A total of 63 children and adolescents who were diagnosed with attention-deficit hyperactivity disorder and fulfilled the inclusion criteria were comprehensively assessed for neurodevelopmental and psychiatric co-morbidities. The tools used included the Mini-International Neuropsychiatric Interview for Children and Adolescents, Attention Deficit Hyperactivity Disorder Rating Scale IV (ADHD-RS), Children's Global Assessment Scale, Clinical Global Impression Scale, Vineland Social Maturity Scale, and Childhood Autism Rating Scale. All except 1 subject had neurodevelopmental and / or psychiatric disorder co-morbid with attention-deficit hyperactivity disorder; 66.7% had both neurodevelopmental and psychiatric disorders. Specific learning disability was the most common co-existing neurodevelopmental disorder and oppositional defiant disorder was the most common psychiatric co-morbidity. The mean baseline ADHD-RS scores were significantly higher in the group with psychiatric co-morbidities, especially in the group with oppositional defiant disorder. Co-morbidity is present at a very high frequency in clinic-referred children diagnosed with attention-deficit hyperactivity disorder. Psychiatric co-morbidity, specifically oppositional defiant disorder, has an impact on the severity of attention-deficit hyperactivity disorder. Co-morbidity needs to be explicitly looked for during evaluation and managed appropriately.

Little is known about within-country variation in morbidity and mortality of cerebrovascular diseases (CVDs). Geographic differences in CVD morbidity and mortality have yet to be properly examined. This study examined geographic variation in morbidity and mortality of CVD, neighborhood factors for CVD morbidity and mortality, and the association between CVD morbidity and mortality across the 245 local districts in Korea during 2011-2015. District-level health care utilization and mortality data were obtained to estimate age-standardized CVD morbidity and mortality. The bivariate Pearson correlation was used to examine the linear relationship between district-level CVD morbidity and mortality Z-scores. Simple linear regression and multivariate analyses were conducted to investigate the associations of area characteristics with CVD morbidity, mortality, and discrepancies between morbidity and mortality. Substantial variation was found in CVD morbidity and mortality across the country, with 1074.9 excess CVD inpatients and 73.8 excess CVD deaths per 100,000 between the districts with the lowest and highest CVD morbidity and mortality, respectively. Higher rates of CVD admissions and deaths were clustered in the noncapital regions. A moderate geographic correlation between CVD morbidity and mortality was found (Pearson correlation coefficient = .62 for both genders). Neighborhood level indicators for socioeconomic disadvantages, undersupply of health care resources, and unhealthy behaviors were positively associated with CVD morbidity and mortality and the relative standing of CVD mortality vis-à-vis morbidity. Policy actions targeting life-course socioeconomic conditions, equitable distribution of health care resources, and behavioral risk factors may help reduce geographic differences in CVD morbidity and mortality in Korea.

Coid, Jeremy; Ullrich, Simone

2010-06-01

Antisocial personality disorder (ASPD) with co-morbid anxiety disorder may be a variant of ASPD with different etiology and treatment requirements. We investigated diagnostic co-morbidity, ASPD criteria, and anxiety/affective symptoms of ASPD/anxiety disorder. Weighted analyses were carried out using survey data from a representative British household sample. ASPD/anxiety disorder demonstrated differing patterns of antisocial criteria, co-morbidity with clinical syndromes, psychotic symptoms, and other personality disorders compared to ASPD alone. ASPD criteria demonstrated specific associations with CIS-R scores of anxiety and affective symptoms. Findings suggest ASPD/anxiety disorder is a variant of ASPD, determined by symptoms of anxiety. Although co-morbid anxiety and affective symptoms are the same as in anxiety disorder alone, associations with psychotic symptoms require further investigation. Copyright 2010 Elsevier Ltd.

To discuss the efficiency of RTS (Revised TraumaScore), ISS (Injury Severity Score), and factors that affect mortality and morbidity in gastrointestinal injuries due to blunt trauma.Method and methods: Patients with gastrointestinal injuries due to blunt trauma operated within the last six years have been studied retrospectively in terms of demographics,injury mechanism and localization, additional injuries, RTS and ISS, operative technique, morbidity, mortality and duration of hospitalization. Of the eighteen cases, cause of injury was a traffic accident for 11 (61.1%), fall from height for 5 (27%) and physical attack for 2 (11%). Among the eighteen patients,there were 21 gastrointestinal injuries (11 intestinal, 6 colon,3 duodenum, 1 stomach). 10 (55.6%) had additional intraabdominal injuries while the number for extra-abdominal injuries were 12 (66.7%). Primary suture (10), segmentary resection (9) and pyloric exclusion (2) were the operations performed for the twenty-one gastrointestinal injuries.Although statistically not significant, 13(72.2%) patients with additional injuries compared with 5 (27.8%) patients with isolated gastrointestinal injuries, were found to have lower RTS (7.087/7.841), higher ISS (19.4/12.2), longer duration of hospitalization (11.5/8.4 day) as well as higher morbidity (7/1) and mortality (2/0) rates. Comparing the RTS (7.059/7.490) of patients who have and have not developed morbidity revealed no significant difference.However, ISS (23.9/12.2) was significantly higher in patients who have developed morbidity (p=0.003). RTS (6.085 7.445) and ISS (39.5/14.6) of patients who have survived were significantly different than patients who have not(p=0.037 and p=0.023, respectively) Additional injuries in patients with gastrointestinal injury due blunt abdominal traumas increases, although not significantly, morbidity, mortality and duration of hospitalization even when operated early. High ISS is significantly related to the risk of both morbidity and mortality while low RTS is significantly related only to the mortality risk. Celsius.

Thirty-one states approved Medicaid expansion after implementation of the Affordable Care Act. The objective of this study was to evaluate the effect of Medicaid expansion on cardiac surgery volume and outcomes comparing one state that expanded to one that did not. Data from the Virginia (nonexpansion state) Cardiac Services Quality Initiative and the Michigan (expanded Medicaid, April 2014) Society of Thoracic and Cardiovascular Surgeons Quality Collaborative were analyzed to identify uninsured and Medicaid patients undergoing coronary bypass graft or valve operations, or both. Demographics, operative details, predicted risk scores, and morbidity and mortality rates, stratified by state and compared across era (preexpansion: 18 months before vs postexpansion: 18 months after), were analyzed. In Virginia, there were no differences in volume between eras, whereas in Michigan, there was a significant increase in Medicaid volume (54.4% [558 of 1,026] vs 84.1% [954 of 1,135], p < 0.001) and a corresponding decrease in uninsured volume. In Virginia Medicaid patients, there were no differences in predicted risk of morbidity or mortality or postoperative major morbidities. In Michigan Medicaid patients, a significant decrease in predicted risk of morbidity or mortality (11.9% [8.1% to 20.0%] vs 11.1% [7.7% to 17.9%], p = 0.02) and morbidities (18.3% [102 of 558] vs 13.2% [126 of 954], p = 0.008) was identified. Postexpansion was associated with a decreased risk-adjusted rate of major morbidity (odds ratio, 0.69; 95% confidence interval, 0.51 to 0.91; p = 0.01) in Michigan Medicaid patients. Medicaid expansion was associated with fewer uninsured cardiac surgery patients and improved predicted risk scores and morbidity rates. In addition to improving health care financing, Medicaid expansion may positively affect patient care and outcomes. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Purpose: For patients with anal canal and advanced rectal cancer, chemoradiation therapy is a curative modality or an important adjunct to surgery. Nearly all patients treated with chemoradiation experience some degree of radiation-induced dermatitis (RID). Prevention and effective treatment of RID, therefore, is of considerable clinical relevance. The present phase III randomized trial compared the efficacy of silver clear nylon dressing (SCND) with that of standard skin care for these patients. Methods and Materials: A total of 42 rectal or anal canal cancer patients were randomized to either a SCND or standard skin care group. SCND was applied from Daymore » 1 of radiation therapy (RT) until 2 weeks after treatment completion. In the control arm, sulfadiazine cream was applied at the time of skin dermatitis. Printed digital photographs taken 2 weeks prior to, on the last day, and two weeks after the treatment completion were scored by 10 blinded readers, who used the common toxicity scoring system for skin dermatitis. Results: The radiation dose ranged from 50.4 to 59.4 Gy, and there were no differences between the 2 groups. On the last day of RT, when the most severe RID occurs, the mean dermatitis score was 2.53 (standard deviation [SD], 1.17) for the standard and 1.67 (SD, 1.2; P=.01) for the SCND arm. At 2 weeks after RT, the difference was 0.39 points in favor of SCND (P=.39). There was considerable intraclass correlation among the 10 observers. Conclusions: Silver clear nylon dressing is effective in reducing RID in patients with lower gastrointestinal cancer treated with combined chemotherapy and radiation treatment.« less

The main objective of this study was to investigate the associations between waist circumference, metabolic risk factors, and executive function in adolescents. The study was cross-sectional and included 558 adolescents (mean age 14.2 years). Anthropometrics and systolic blood pressure (sysBP) were measured and fasting blood samples were analyzed for metabolic risk factors. A metabolic risk factor cluster score (MetS-cluster score) was computed from the sum of standardized sysBP, triglycerides (TG), inverse high-density lipid cholesterol (HDLc) and insulin resistance (homeostasis model assessment). Cognitive control was measured with a modified flanker task. Regression analyses indicated that after controlling for demographic variables, HDLc exhibited a negative and TG a positive association with flanker reaction time (RT). Waist circumference did not demonstrate a statistically significant total association with the cognitive outcomes. In structural equation modeling, waist circumference displayed an indirect positive association with incongruent RT through a higher MetS-cluster score and through lower HDLc. The only statistically significant direct association between waist circumference and the cognitive outcomes was for incongruent RT in the model including HDLc as mediator. These findings are consonant with the previous literature reporting an adverse association between certain metabolic risk factors and cognitive control. Accordingly, these results suggest specificity between metabolic risk factors and cognitive control outcomes. Further, results of the present study, although cross-sectional, provide new evidence that specific metabolic risk factors may mediate an indirect association between adiposity and cognitive control in adolescents, even though a direct association between these variables was not observed. However, taking the cross-sectional study design into consideration, these results should be interpreted with caution and future longitudinal or experimental studies should verify the findings of this study.

The purpose of this study was to evaluate the relationship between sports experience (i.e., tennis experience) and executive function in children while controlling for physical activity and physical fitness. Sixty-eight participants (6-12 years old, 34 males and 34 females) were enrolled in regular tennis lessons (mean = 2.4 years, range = 0.1-7.3 years) prior to the study. Executive functions, including inhibitory control (the Stroop Color-Word Test), working memory (the 2-back Task), and cognitive flexibility (the Local-global Task) were evaluated. Participants' levels of daily physical activity, ranging from moderate to vigorous, were evaluated using triaxial accelerometers. The total score for physical fitness was assessed using the Tennis Field Test. Hierarchical multiple regression analyses revealed interaction effects between gender and tennis experience on participants' reaction time (RT) on the switch cost of the Local-global Task after controlling for age, BMI, gender, physical activity, physical fitness, and tennis experience. Longer tennis experience was associated with shorter switch cost in males but not in females. Higher scores on physical fitness were positively associated with lower interference scores on the Stroop Color-Word Test, RT on the 2-back Task, and RT in the switching condition of the Local-global Task, after controlling for age, BMI, gender, and physical activity. In conclusion, all three foundational components of executive function (i.e., inhibitory control, working memory, and cognitive flexibility) were more strongly related to physical fitness than to physical activity in males and females, whereas greater cognitive flexibility was related to tennis experience only in the males. © 2017 John Wiley & Sons Ltd.

Lower urinary tract symptoms (LUTSs) affect 75%-80% of men undergoing radiation therapy (RT) for prostate cancer. To determine the safety, maximum tolerated dose (MTD), and preliminary efficacy of Serenoa repens commonly known as saw palmetto (SP) for management of LUTS during RT for prostate cancer. The dose finding phase used the time-to-event continual reassessment method to evaluate safety of three doses (320, 640, and 960 mg) of SP. Dose-limiting toxicities were assessed for 22 weeks using the Common Terminology Criteria for Adverse Events for nausea, gastritis, and anorexia. The exploratory randomized controlled trial phase assessed preliminary efficacy of the MTD against placebo. The primary outcome of LUTS was measured over 22 weeks using the International Prostate Symptom Score. Additional longitudinal assessments included quality of life measured with the Functional Assessment of Cancer Therapy-Prostate. The dose finding phase was completed by 27 men who reported no dose-limiting toxicities and with 20 participants at the MTD of 960 mg daily. The exploratory randomized controlled trial phase included 21 men, and no statistically significant differences in the International Prostate Symptom Score were observed. The prostate-specific concerns score of the Functional Assessment of Cancer Therapy-Prostate improved in the SP group (P = 0.03). Of 11 men in the placebo group, two received physician-prescribed medications to manage LUTS compared with none of the 10 men in the SP group. SP at 960 mg may be a safe herbal supplement, but its efficacy in managing LUTS during RT needs further investigation. Copyright © 2016 American Academy of Hospice and Palliative Medicine.

Rational development of technology for rapid control of noncompressible torso hemorrhage (NCTH) requires detailed understanding of what is bleeding. Our objectives were to describe the anatomic location of truncal bleeding in patients presenting with NCTH and compare endovascular (ENDO) management versus open (OPEN) management. This is a retrospective study of adult trauma patients with NCTH admitted to four urban Level I trauma centers in the Houston and San Antonio metropolitan areas in 2008 to 2012. Inclusion criteria include named axial torso vessel disruption, Abbreviated Injury Scale chest or abdomen score of 3 or higher with shock (base excess, <-4) or truncal operation in 90 minutes or less, or pelvic fracture with ring disruption. Exclusion criteria include isolated hip fractures, falls from standing, or prehospital cardiopulmonary resuscitation. After dichotomizing into OPEN, ENDO, and resuscitative thoracotomy (RT) groups based on the initial approach to control NCTH, a mixed-effects Poisson regression with robust error variance (controlling for age, mechanism, Injury Severity Score, shock, hypotension, and severe head injury as fixed effects and site as a random effect) was used to test the hypothesis that ENDO was associated with reduced in-hospital mortality in NCTH patients. Five hundred forty-three patients with NCTH underwent ENDO (n = 166, 31%), OPEN (n = 309, 57%), or RT (n = 68, 12%). Anatomic bleeding locations were 25% chest, 41% abdomen, and 31% pelvis. ENDO was used to treat relatively few types of vascular injuries, whereas OPEN and RT injuries were more diverse. ENDO patients had more blunt trauma (95% vs. 34% vs. 32%); severe injuries (median Injury Severity Score, 34 vs. 27 vs. 21), and increased time to intervention (median, 298 vs. 92 vs. 51 minutes) compared with OPEN and RT. Mortality was 15% versus 20% versus 79%. ENDO was associated with decreased mortality compared to OPEN (relative risk, 0.58; 95% confidence interval, 0.46-0.73). Although ENDO may reduce mortality in NCTH patients, significant group differences limit the generalizability of this finding. Therapeutic, level V.

To evaluate return-to-activity (RtA) after anatomical reconstruction of acute high-grade acromioclavicular joint (ACJ) separation. A total of 42 patients with anatomical reconstruction of acute high-grade ACJ-separation (Rockwood Type V) were surveyed to determine RtA at a mean 31 months follow-up (f-u). Sports disciplines, intensity, level of competition, participation in overhead and/or contact sports, as well as activity scales (DASH-Sport-Module, Tegner Activity Scale) were evaluated. Functional outcome evaluation included Constant score and QuickDASH. All patients (42/42) participated in sporting activities at f-u. Neither participation in overhead/contact sports, nor level of activity declined significantly (n.s.). 62 % (n = 26) of patients reported subjective sports specific ACJ integrity to be at least the same as prior to the trauma. Sporting intensity (hours/week: 7.3 h to 5.4 h, p = .004) and level of competition (p = .02) were reduced. If activity changed, in 50 % other reasons but clinical symptoms/impairment were named for modified behavior. QuickDASH (mean 6, range 0-54, SD 11) and DASH-Sport-Module (mean 6, range 0-56, SD 13) revealed only minor disabilities at f-u. Over time Constant score improved significant to an excellent score (mean 94, range 86-100, SD 4; p < .001). Functional outcome was not correlated with RtA (n.s.). All patients participated in sporting activities after anatomical reconstruction of high-grade (Rockwood Type V) ACJ-separation. With a high functional outcome there was no significant change in activity level (Tegner) and participation in overhead and/or contact sports observed. There was no correlation between functional outcome and RtA. Limiting, there were alterations in time spent for sporting activities and level of competition observed. But in 50 % those were not related to ACJ symptoms/impairment. Unrelated to successful re-established integrity and function of the ACJ it should be considered that patients decided not return-to-activity but are very content with the procedure.

To identify whether a certain group of breast ductal carcinoma-in-situ (DCIS) patients can be treated with breast-conserving surgery (BCS) alone; to analyze the clinicopathologic features of DCIS and tamoxifen administration in patients treated with BCS who developed ipsilateral breast tumor recurrence (IBTR). Data for 375 women with breast DCIS who underwent BCS at our institute between June 2003 and October 2010 were analyzed. The patients were divided into different categories according to the recurrence risk predicted using the California/Van Nuys Prognostic Index (USC/VNPI) score (4-6, 7-9, and 10-12), Eastern Cooperative Oncology Group (ECOG) E5194 criteria, or combined risk features with USC/VNPI score and ECOG E5194 criteria. The IBTR and disease-free survival (DFS) rates were calculated by the Kaplan-Meier method. The prognostic effects of age, tumor size, tumor grade, margin width, estrogen receptor status, USC/VNPI score, low-risk characteristics, and tamoxifen use were evaluated by log-rank tests. Of the patients, 168 were treated with breast irradiation after BCS and 207 were not. The patients who were treated with radiotherapy (RT) tended to be younger (< 40 years), to have higher USC/VNPI scores (7-9), and to meet the ECOG E5194 non-cohort 1 criteria. The 7-year risk of IBTR was 6.2% (n = 11) in the patients who received irradiation and 9.0% (n = 22) in those who did not. DFS rates were better in the patients who underwent RT than in those who did not (93.3% vs. 88.5%, P = .056). Among the patients who underwent BCS alone, age ≥ 40 years, margin width > 10 mm, USC/VNPI scores 4-6, ECOG E5194 cohort 1 criteria, estrogen receptor-positive status, and tamoxifen use predicted lower IBTR and better DFS rates. In the multivariate analysis, combined low-risk characteristics (USC/VNPI scores 4-6 and meeting the ECOG E5194 cohort 1 criteria) were identified as an independent prognostic factor of lower IBTR (P = .028) and better DFS (P = .005). RT reduces the risk of IBTR after BCS for DCIS of the breast. Patients with combined low-risk characteristics (USC/VNPI scores 4-6 and meeting the ECOG E5194 cohort 1 criteria) may be adequately treated with BCS alone. Copyright © 2018 Elsevier Inc.

The objective is to examine the effects of reminiscence therapy (RT) on total, episodic and semantic autobiographical memory in amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) groups, testing the effects of RT on different stages of autobiographical memory, and its effectiveness at follow-up. A sample composed of 43 aMCI (27 treatments, 16 controls) and 30 AD (15 treatments, 15 controls) subjects were evaluated with the Autobiographical Memory Interview (AMI) test. The RT consisted of 10 sessions lasting 60 minutes each. Both groups, aMCI and AD, showed significant effects on overall autobiographical memory; aMCI showed significant main effects on episodic and semantic autobiographical memory in the treatment group, increasing scores in both cases. For AD, significant effects were observed on autobiographical episodic memory, showing an increase in the treatment group from Time 1 to follow-up; semantic memory showed a decrease in the control group from Time 1 to follow-up. Results show that RT implementation and follow-up are effective in increasing autobiographical memory in subjects with aMCI and AD. © 2015 International Union of Psychological Science.

To determine the long-term outcomes of a prospective cohort of 20 patients who had nasopharyngectomy using an open partial-maxillectomy approach. A prospective cohort study of the surgical outcomes of patients with recurrent T1 (rT1) and rT2 nasopharyngeal carcinoma recurrence. There were 14 male and six female patients. The mean age was 49 years. The mean duration of follow-up was 60.4 months. All of the surgical margins were free of malignancy. Ten patients (50%) developed recurrences. The 5-year local control rate, disease-free, disease-specific, and overall survivals were 70%, 48.9%, 70.2%, and 66.7%, respectively. There were no major intraoperative complications. The most common morbidity was pain. The median length of hospitalization was 4 days. Early local recurrence of nasopharyngeal carcinoma can be treated surgically using a partial maxillectomy approach. The long-term outcomes are similar to nasopharyngectomy performed using the more common approaches. 4.

We have characterized in this study 10 PPMV-1 isolated from domestic pigeons and one PPMV-1 isolated from a feral pigeon in the period 2007-2012, using both classical methods (HI test and ICPI test) and molecular methods (RT-qPCR, RT-PCR, and nucleotide sequencing). Using phylogenetic analysis of partial fusion gene sequences, these viruses clustered with recent European PPMV-1 isolates (EU/re) within the genotype VIb/1. All isolates possessed virulent cleavage site motifs with variable morbidity and mortality in pigeons. The intracerebral pathogenecity indices of the five isolates ranged from 0.59 to 1.53. The repetitive isolation of PPMV-1 viruses for several consecutive years led toward establishing enzootic presence of the disease in pigeons. A high nucleotide sequence homology between the Macedonian isolates and EU/re isolates was shown. Co-circulation of different isolates in the same holdings was detected. This is the first study to extensively describe the molecular epidemiology of PPMV-1 isolated in Macedonia.

The ultimate cause of death for most patients with newly diagnosed chronic lymphocytic leukaemia (CLL) and its relationship to co-morbid health conditions is poorly defined. We conducted a prospective cohort study that systematically followed 1143 patients diagnosed with CLL between June 2002 and November 2014. Comorbid health conditions at the time of CLL diagnosis and their relationship to survival and cause of death were evaluated. Collectively, 1061 (93%) patients had at least one co-morbid health condition at the time of CLL diagnosis (median number 3). Despite this, 89% of patients had a low-intermediate Charlson Comorbidity Index score (CCI) at diagnosis. After a median follow-up of 6 years, 225 patients have died. Death was due to CLL progression in 85 (46%) patients, infection in 14 (8%) patients, other cancer in 35 (19%) patients and comorbid health conditions in 50 (27%) patients. Higher CCI score and a greater number of major comorbid health conditions at the time of CLL diagnosis was associated with shorter non-CLL specific survival, but not with shorter CLL-specific survival on multivariate analysis. In conclusion, CLL and CLL-related complications (infections and second cancers) are the overwhelming cause of death in patients with CLL, regardless of CCI score and number of comorbid health conditions at diagnosis. © 2017 John Wiley & Sons Ltd.

The interrater reliability of lactation assessment tools has not been evaluated in overweight/obese women. This study aimed to compare the interrater reliability of 4 lactation assessment tools in this population. A convenience sample of 45 women (body mass index > 27.0) was videotaped while breastfeeding (twice daily on days 2, 4, and 7 postpartum). Three International Board Certified Lactation Consultants independently rated each videotaped session using 4 tools (Infant Breastfeeding Assessment Tool [IBFAT], modified LATCH [mLATCH], modified Via Christi [mVC], and Riordan's Tool [RT]). For each day and tool, we evaluated interrater reliability with 1-way repeated-measures analyses of variance, intraclass correlation coefficients (ICCs), and percentage absolute agreement between raters. Analyses of variance showed significant differences between raters' scores on day 2 (all scales) and day 7 (RT). Intraclass correlation coefficient values reflected good (mLATCH) to excellent reliability (IBFAT, mVC, and RT) on days 2 and 7. All day 4 ICCs reflected good reliability. The ICC for mLATCH was significantly lower than all others on day 2 and was significantly lower than IBFAT (day 7). Percentage absolute interrater agreement for scale components ranged from 31% (day 2: observable swallowing, RT) to 92% (day 7: IBFAT, fixing; and mVC, latch time). Swallowing scores on all scales had the lowest levels of interrater agreement (31%-64%). We demonstrated differences in the interrater reliability of 4 lactation assessment tools when applied to overweight/obese women, with the lowest values observed on day 4. Swallowing assessment was particularly unreliable. Researchers and clinicians using these scales should be aware of the differences in their psychometric behavior. © The Author(s) 2015.

This study aimed to evaluate the effects of warm-mist humidification during and after head and neck radiation therapy (HN RT) on quality of life (QOL), as measured by the M. D. Anderson Symptom Inventory-Head and Neck (MDASI-HN) HN score. A secondary aim was to compare QOL among compliers (≥60% of protocol-recommended usage) versus non-compliers. Twenty patients self-administered a hand-held, self-sterilizing humidification device for a recommended time of at least 15 min twice daily for 12 weeks. Patients completed the MDASI-HN instrument at RT start, after 6 weeks, and after 12 weeks. Compliance was reported weekly. The average HN score at baseline was 1.7 (SD = 1.8) and increased to 6.0 (SD = 1.6) after 6 weeks; this increase was much higher than anticipated and the primary endpoint could not be reached. However, compliers had an average of nearly two less HN symptoms (-1.8, 95% CI -4 to 0.2; p = 0.08) than non-compliers at 6 weeks and fewer symptoms at 12 weeks as well (-0.9, 95% CI -2.9 to 1.2; p = 0.39). The most common terms patients used to describe humidification were "helpful" and "soothing." Compliance with humidification during RT was associated with fewer reported HN symptoms and a strong trend to better QOL. Improvements were seen from compliance with occasional required use of a portable, inexpensive device. Our findings support continued efforts to reduce barriers to humidification, as an intervention that should be considered for standard HN RT clinical practice.

The survival outcome of patients with unresectable hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) who received transarterial chemoembolization (TACE) combined with radiotherapy (RT) remains unclear. A total of 112 and 735 HCC patients with PVTT undergoing TACE combined with RT and TACE alone, respectively, were evaluated. One hundred and eight pairs of matched patients were selected from each treatment arm by using a propensity score matching (PSM) analysis. Of the whole study population, TACE combined with RT showed significant survival benefits compared with TACE in all patients (median survival, 11.0 vs 4.8 months; P < 0.001), especially in patients with PVTT involving the right/left portal vein (median survival, 12.5 vs 5.2 months; P < 0.001) and main portal vein trunk (median survival, 8.9 vs 4.3 months; P < 0.001). After one-to-one PSM, 108 pairs of matched patients were selected for further analysis. In the propensity model, the median survival time was 10.9 versus 4.1 months (P < 0.001) in all patients, 12.5 versus 4.4 months (P = 0.002) in patients with PVTT involving the right/left portal vein and 8.9 versus 4.0 months (P < 0.001) in patients with PVTT involving the main portal vein trunk. The treatment, maximum lesion diameter and main trunk PVTT were the independent prognostic factors for survival at uni- and multivariate analysis. TACE combined with RT provides a significantly better survival outcome than TACE for unresectable HCC patients with PVTT, especially for patients with PVTT involving the right/left portal vein or main trunk. © 2016 The Japan Society of Hepatology.

There is an ongoing debate about whether robotic thyroidectomy (RT) is appropriate for Graves' disease. The aim of this study was to compare the safety of bilateral axillo-breast approach (BABA) RT with that of open thyroidectomy (OT) in patients with Graves' disease. From January 2008 to June 2014, 189 (44 BABA RT and 145 OT) patients underwent total thyroidectomy for Graves' disease. Recurrence of Graves' disease, intraoperative blood loss, hospital stay, and complication rates including recurrent laryngeal nerve (RLN) palsy and hypoparathyroidism were analyzed between BABA RT and OT groups, after propensity score matching according to age, gender, body mass index, surgical indication, the extent of operation, excised thyroid weight, and follow-up period. No patient experienced recurrence of Graves' disease after median follow-up of 35.0 months. Intraoperative blood loss (151.8 ± 165.4 mL vs. 134.5 ± 75.4 mL; p = 0.534) and hospital stay (3.4 ± 0.7 day vs. 3.3 ± 0.7 day; p = 0.564) were not different between BABA RT and OT groups. Complication rates including transient RLN palsy (11.4 vs. 11.4%; p = 1.000), transient hypoparathyroidism (18.2 vs. 20.5%; p = 0.787), permanent RLN palsy (0 vs. 2.3%; p = 0.315), and permanent hypoparathyroidism (2.3 vs. 2.3%; p = 1.000) were also comparable between groups. BABA RT for Graves' disease showed comparable surgical completeness and complications to conventional OT. BABA RT can be recommended as an alternative surgical option for patients with Graves' disease who are concerned about cosmesis.

Purpose: Adjuvant radiotherapy (RT) is often considered for endometrial cancer. We studied the effect of RT and surgical treatment on patients' quality of life (QOL). Methods and Materials: All patients referred to the gynecologic oncology clinics with biopsy findings showing endometrial cancer were recruited. QOL assessments were performed using the European Organization for Research and Treatment of Cancer QOL questionnaire-C30, version 3. Assessments were obtained at study entry and at regular 3-month intervals for a maximum of 2 years. Open-ended telephone interviews were done every 6 months. Linear mixed regression models were built using QOL domain scores as dependent variables,more » with the predictors of surgical treatment and adjuvant RT type. Results: A total of 40 patients were recruited; 80% of the surgeries were performed by laparotomy. Significant improvements were seen in most QOL domains with increased time from treatment. Adjuvant RT resulted in significantly more severe bowel symptoms and improvement in insomnia compared with conservative follow-up. No significant adverse effect from adjuvant RT was seen on the overall QOL. Bowel symptoms were significantly increased in patients treated with laparotomy compared with laparoscopy in the patients treated with whole pelvic RT. Qualitatively, about one-half of the patients noted improvements in their overall QOL during follow-up, with easy fatigability the most prevalent. Conclusion: No significant adverse effect was seen on patients' overall QOL with adjuvant pelvic RT after the recovery period. The acute adverse effects on patients' QOL significantly improved with an increasing interval from diagnosis.« less

2012-05-01

In this pilot study, we compared two protocols for robot-based rehabilitation of upper limb in multiple sclerosis (MS): a protocol involving reaching tasks (RT) requiring arm transport only and a protocol requiring both objects' reaching and manipulation (RMT). Twenty-two MS subjects were assigned to RT or RMT group. Both protocols consisted of eight sessions. During RT training, subjects moved the handle of a planar robotic manipulandum toward circular targets displayed on a screen. RMT protocol required patients to reach and manipulate real objects, by moving the robotic arm equipped with a handle which left the hand free for distal tasks. In both trainings, the robot generated resistive and perturbing forces. Subjects were evaluated with clinical and instrumental tests. The results confirmed that MS patients maintained the ability to adapt to the robot-generated forces and that the rate of motor learning increased across sessions. Robot-therapy significantly reduced arm tremor and improved arm kinematics and functional ability. Compared to RT, RMT protocol induced a significantly larger improvement in movements involving grasp (improvement in Grasp ARAT sub-score: RMT 77.4%, RT 29.5%, p=0.035) but not precision grip. Future studies are needed to evaluate if longer trainings and the use of robotic handles would significantly improve also fine manipulation.

Storytelling for promoting colorectal cancer screening among underserved Latina women: a randomized pilot study.

2009-01-01

In a low socioeconomic-status population of Latina women, we evaluated the potential of storytelling (ST) as a culturally aligned narrative method to promote colorectal cancer (CRC) prevention and screening, compared to a risk tool (RT)-based intervention. Seventy-eight women were randomized in this pilot study to one of two brief interventions to communicate CRC risk reduction options: ST or an RT. Measures of behavioral intentions relative to CRC prevention and screening were obtained following the intervention. Mean scores for intent to obtain and recommend endoscopy to others were significantly better for participants receiving ST than RT (P = .038 and P = .011, respectively). All participants expressed intent to increase fruit and vegetable consumption and physical activity in response to interventions. Post-intervention perceptions of cancer risk and fear of CRC were not significantly different for participants receiving ST compared with RT. Pre- to post-intervention perceptions of risk increased in ST and decreased in RT, while decreases in fear were similar across both intervention groups. Storytelling may be an effective approach for changing CRC risk-related behavioral intentions among Latinas. Mediating factors (such as perceived risk or fear) often used to predict behavior change may not adequately explain the potential persuasive mechanisms of storytelling.

We examined adult age differences in day-to-day adjustments in speed-accuracy tradeoffs (SAT) on a figural comparison task. Data came from the COGITO study, with over 100 younger and 100 older adults, assessed for over 100 days. Participants were given explicit feedback about their completion time and accuracy each day after task completion. We applied a multivariate vector auto-regressive model of order 1 to the daily mean reaction time (RT) and daily accuracy scores together, within each age group. We expected that participants adjusted their SAT if the two cross-regressive parameters from RT (or accuracy) on day t-1 of accuracy (or RT) on day t were sizable and negative. We found that: (a) the temporal dependencies of both accuracy and RT were quite strong in both age groups; (b) younger adults showed an effect of their accuracy on day t-1 on their RT on day t, a pattern that was in accordance with adjustments of their SAT; (c) older adults did not appear to adjust their SAT; (d) these effects were partly associated with reliable individual differences within each age group. We discuss possible explanations for older adults' reluctance to recalibrate speed and accuracy on a day-to-day basis.

Radiation therapy (RT) for esophageal cancer often results in unintended radiation doses delivered to the heart owing to anatomic proximity. Using the Surveillance, Epidemiology, and End Results (SEER) database, we examined late cardiac death in survivors of esophageal cancer that had or had not received RT. 5,630 patients were identified that were diagnosed with esophageal squamous cell carcinoma (SCC) or adenocarcinoma (AC) from 1973-2012, who were followed for at least 5 years after therapy. Examined risk factors for cardiac death included age (≤55/56-65/66-75/>75), gender, race (white/non-white), stage (local/regional/distant), histology (SCC/AC), esophageal location (<18cm/18-24cm/25-32cm/33-40cm from incisors), diagnosis year (1973-1992/1993-2002/2003-2012), and receipt of surgery and/or RT. Time to cardiac death was evaluated using the Kaplan-Meier method. A Cox model was used to evaluate risk factors for cardiac death in propensity score matched data. Patients who received RT were younger, diagnosed more recently, had more advanced disease, SCC histology, and no surgery. The RT group had higher risk of cardiac death than the no-RT group (log-rank p<0.0001). The median time to cardiac death in the RT group was 289 months (95% CI, 255-367) and was not reached in the no-RT group. The probability of cardiac death increased with age and decreased with diagnosis year, and this trend was more pronounced in the RT group. Multivariate analysis found RT to be associated with higher probability of cardiac death (OR 1.23, 95% CI 1.03-1.47, HR 1.961, 95% CI 1.466-2.624). Lower esophageal subsite (33-40 cm) was also associated with a higher risk of cardiac death. Other variables were not associated with cardiac death. Recognizing the limitations of a SEER analysis including lack of comorbidity accountability, these data should prompt more definitive study as to whether a possible associative effect of RT on cardiac death could potentially be a causative effect.

Gill, Beant S.; Vargo, John A.; Pai, Sarah S.

Purpose: Mantle cell lymphoma (MCL) is a rare, albeit aggressive subset of non-Hodgkin lymphoma, resulting in varied treatment approaches. Given the paucity of data defining the optimal management for early-stage MCL, we conducted an analysis using the National Cancer Data Base (NCDB) to identify practice patterns and outcomes. Methods and Materials: The NCDB was queried for patients with stage I to II MCL diagnosed from 1998 to 2012 receiving chemotherapy (CT) or radiation therapy (RT), or both (CT+RT). Univariate and multivariable analyses for factors associated with treatment selection were completed using logistic regression. Propensity scores with inverse probability treatment weightingmore » (IPTW) were calculated based on the conditional probability of receiving CT+RT. The log-rank test and Cox proportional hazards modeling with IPTW adjustment were conducted for the survival analyses. Results: In total, 2539 patients were identified. The key characteristics were as follows: 69% were male, 71% were aged ≥60 years, 28% had extranodal involvement, and 51% had stage I disease. Of the 2539 patients, 70% underwent CT, 11% underwent RT, and 19% underwent CT+RT. The use of CT+RT decreased from 23.1% to 14.1% in 1998 to 2002 and 2010 to 2012 (P<.001). CT+RT usage was lower for patients with the following characteristics: age ≥60 years, female sex, stage II disease, and the presence of B symptoms. With a median follow-up period of 42.8 months, the unadjusted 3-year overall survival estimates for patients receiving CT, RT, or CT+RT were 67.8%, 72.4%, and 79.8%, respectively (P<.001). After correcting for indication bias through IPTW-adjusted modeling, CT+RT reduced the risk of overall mortality compared with monotherapy (hazard ratio 0.65, P=.029). Conclusions: Although uncommon, patients with stage I-II MCL can have favorable outcomes. Despite a continued decline in the usage of consolidative RT, combined modality therapy improves survival in this cohort compared with monotherapy.« less

M2 occlusions may result in poor outcomes and potentially benefit from endovascular therapy. Data on the rate of M2 strokes is lacking. Patients with acute ischemic stroke discharged over a period of 3 years from a tertiary level hospital in the 'stroke belt' were evaluated for M2 occlusions on baseline vascular imaging. Regional and national incidence was calculated from discharge and multicounty data. There were 2739 ICD-9 based AIS discharges. M2 occlusions in 116 (4%, 95% CI 3.5% to 5%) patients constituted the second most common occlusion site. The median National Institute of Health Stroke Scale (NIHSS) score was 12 (IQR 5-18). Good outcomes were observed in 43% (95% CI 34% to 53%), poor outcomes in 57% (95% CI 47% to 66%), and death occurred in 27% (95% CI 19% to 37%) of patients. Receiver operating characteristics curves showed the NIHSS to be predictive of outcomes (area under the curve 0.829, 95% CI 0.745 to 0.913, p<0.0001). An NIHSS score ≥9 was the optimal cut-off point for predicting poor outcomes (sensitivity 85.7%, specificity 67.4%). 71 (61%) patients had an NIHSS score ≥9 and 45 (39%) an NIHSS score <9. The rate of good-outcome was 22.6% for NIHSS score ≥9 versus 78.4% for NIHSSscore <9 (OR=0.08, 95% CI 0.03 to 0.21, p<0.0001). Mortality was 42% for NIHSS score ≥9 versus 2.7% for NIHSS score <9 (OR=26, 95% CI 3.3 to 202, p<0.0001). Infarct volume was 57 (±55.7) cm 3 for NIHSS score ≥9 versus 30 (±34)cm 3 for NIHSS score <9 (p=0.003). IV recombinant tissue plasminogen activator (rtPA) administered in 28 (24%) patients did not affect outcomes. The rate of M2 occlusions was 7 (95% CI 5 to 9)/100 000 people/year (3%, 95% CI 2% to 4%), giving an incidence of 21 176 (95% CI 15 282 to 29 247)/year. Combined with M1, internal carotid artery terminus and basilar artery, this yields a 'large vessel occlusion (LVO)+M2' rate of 31 (95% CI 26 to 35)/100 000 people/year and a national incidence of 99 227 (95% CI 84 004 to 112 005) LVO+M2 strokes/year. M2 occlusions can present with serious neurological deficits and cause significant morbidity and mortality. Patients with M2 occlusions and higher baseline deficits (NIHSS score ≥9) may benefit from endovascular therapy, thus potentially expanding the category of acute ischemic strokes amenable to intervention. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Salvage laryngectomy (SL) is associated with high levels of morbidity. Rates of pharyngocutaneous fistulae (PCF) are as high as 35 % in some series. Patients at highest risk of such complications may be candidates for altered surgical management in terms of additional tissue transfer, or delayed tracheoesophageal puncture. This study investigates the relationship between the time from primary radiotherapy (RT) to salvage surgery and the development of PCF. 26 consecutive patients who underwent SL between 2000 and 2010 were identified from our institutional database. Demographic, staging, treatment and complication data were collected. Subgroup analysis was performed using the Student's t test or Mann-Whitney U test for continuous variables and either Chi-squared test or Fisher's Exact test for categorical variables. 26 patients underwent SL between October 2003 and July 2010. Of these, 15 (58 %) developed a PCF. On analysis of the time between pre-operative RT and surgery, a significant difference was seen, with a mean time of 19.5 months in those who developed a PCF versus 47.0 months in those who did not (p = 0.02). Patient characteristics, treatment, and pathology results were comparable between the two groups. There was no significant difference in distribution of the other covariates between the PCF and non-PCF groups. We reported a high rate of PCF and identified an association between PCF and a short time from primary treatment to salvage surgery. Identifying factors associated with higher rates of post-operative morbidity allows surgeons to adapt surgical planning in an attempt to minimize rates of PCF.

We analysed the complications of 215 patients with uterine cervix cancer, treated by radiotherapy (RT) alone. It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

The purpose of the present study was to investigate whether inconsistency in reaction time (RT) is predictive of older adults' ability to solve everyday problems. A sample of 304 community dwelling non-demented older adults, ranging in age from 62 to 92, completed a measure of everyday problem solving, the Everyday Problems Test (EPT). Inconsistency in latencies across trials was assessed on four RT tasks. Performance on the EPT was found to vary according to age and cognitive status. Both mean latencies and inconsistency were significantly associated with EPT performance, such that slower and more inconsistent RTs were associated with poorer everyday problem solving abilities. Even after accounting for age, education, and mean level of performance, inconsistency in reaction time continued to account for a significant proportion of the variance in EPT scores. These findings suggest that indicators of inconsistency in RT may be of functional relevance.

The traditional drug design strategy centrally focuses on optimizing binding affinity with the receptor target and evaluates pharmacokinetic properties at a later stage which causes high rate of attrition in clinical trials. Alternatively, parallel screening allows evaluation of these properties and affinity simultaneously. In a case study to identify leads from natural compounds with experimental HIV-1 reverse transcriptase (RT) inhibition, we integrated various computational approaches including Caco-2 cell permeability QSAR model with applicability domain (AD) to recognize drug-like natural compounds, molecular docking to study HIV-1 RT interactions and shape similarity analysis with known crystal inhibitors having characteristic butterfly-like model. Further, the lipophilic properties of the compounds refined from the process with best scores were examined using lipophilic ligand efficiency (LLE) index. Seven natural compound hits viz. baicalien, (+)-calanolide A, mniopetal F, fagaronine chloride, 3,5,8-trihydroxy-4-quinolone methyl ether derivative, nitidine chloride and palmatine, were prioritized based on LLE score which demonstrated Caco-2 well absorption labeling, encompassment in AD structural coverage, better receptor affinity, shape adaptation and permissible AlogP value. We showed that this integrative approach is successful in lead exploration of natural compounds targeted against HIV-1 RT enzyme.

Objective To assess how the inclusion of diagnoses from complementary and alternative medicine (CAM) providers affects measures of morbidity burden and expectations of health care resource use for insured patients. Methods Claims data from Washington State were used to create two versions of a case-mix index. One version included claims from all provider types; the second version omitted claims from CAM providers who are covered under commercial insurance. Expected resource use was also calculated. The distribution of expected and actual resource use was then compared for the two indices. Results Inclusion of CAM providers shifts many patients into higher morbidity categories; 54% of 61,914 CAM users had higher risk scores in the index which included CAM providers. When expected resource use categories were defined based on all providers, CAM users in the highest morbidity category had average (± s.d.) annual expenditures of $6661 (± $13,863). This was less than those in the highest morbidity category when CAM providers were not included in the index ($8562 ± $16,354), and was also lower than the highest morbidity patients who did not use any CAM services ($8419 ± $18,885). Conclusions Inclusion of services from CAM providers under third party payment increases risk scores for their patients but expectations of costs for this group are lower than expected had costs been estimated based only on services from traditional providers. Additional work is needed to validate risk adjustment indices when adding services from provider groups not included in the development of the index. PMID:17122711

Purpose: The role of pelvic elective nodal irradiation (ENI) in the management of prostate cancer is controversial. This study analyzed the role of pelvic radiation therapy (RT) on the outcome in high-risk localized prostate cancer patients included in the Groupe d'Etude des Tumeurs Uro-Genitales (GETUG) 12 trial. Methods and Materials: Patients with a nonpretreated high-risk localized prostate cancer and a staging lymphadenectomy were randomly assigned to receive either goserelin every 3 months for 3 years and 4 cycles of docetaxel plus estramustine or goserelin alone. Local therapy was administered 3 months after the start of systemic treatment. Performance of pelvic ENI was leftmore » to the treating physician. Only patients treated with primary RT were included in this analysis. The primary endpoint was biochemical progression-free survival (bPFS). Results: A total of 413 patients treated from 2002 to 2006 were included, of whom 358 were treated using primary RT. A total of 208 patients received pelvic RT and 150 prostate-only RT. Prostate-specific antigen (PSA) concentration, Gleason score, or T stage did not differ according to performance of pelvic RT; pN+ patients more frequently received pelvic RT than pN0 patients (P<.0001). Median follow-up was 8.8 years. In multivariate analysis, bPFS was negatively impacted by pN stage (hazard ratio [HR]: 2.52 [95% confidence interval [CI]: 1.78-3.54], P<.0001), Gleason score 8 or higher (HR: 1.41 [95% CI: 1.03-1.93], P=.033) and PSA higher than 20 ng/mL (HR: 1.41 [95% CI: 1.02-1.96], P=.038), and positively impacted by the use of chemotherapy (HR: 0.66 [95% CI: 0.48-0.9], P=.009). There was no association between bPFS and use of pelvic ENI in multivariate analysis (HR: 1.10 [95% CI: 0.78-1.55], P=.60), even when analysis was restricted to pN0 patients (HR: 0.88 [95% CI: 0.59-1.31], P=.53). Pelvic ENI was not associated with increased acute or late patient reported toxicity. Conclusions: This unplanned analysis of a randomized trial failed to demonstrate a benefit of pelvic ENI on bPFS in high-risk localized prostate cancer patients.« less

•  To determine the proportion of patients with overactive bladder (OAB) potentially at risk for adverse events by assessing their pre-existing central nervous system (CNS), cardiovascular (CV) and other co-morbidities. •  The GE Centricity Electronic Medical Record database was utilized to identify patients with a diagnosis of OAB using International Classification of Diseases, Ninth Revision (ICD-9) codes or a prescription between 1 January 1996 and 30 March 2007 for an OAB anti-muscarinic agent. •  Matched non-OAB patients were assigned the same index date as the corresponding OAB patient. Based on the presence of ≥ one pharmacy claim for an OAB anti-muscarinic agent, the OAB cohort was stratified as treated or untreated. A random sample of age- and gender-matched patients formed a non-OAB control cohort. •  An additional and separate analysis focusing on all co-morbidities was performed examining non-OAB patients who were matched to OAB patients on 1:1 propensity score matching, based on age, body mass index (BMI) and gender at baseline. •  Charlson Comorbidity Index (CCI), using ICD-9 codes, and the Chronic Disease Score (CDS), using prescribed drugs, were calculated. •  When compared with non-OAB patients (N= 77,272; 83.2% women; median age 64 years), OAB patients (N= 41,440; 83.6% women; median age 65 years) had more overall CNS co-morbidities (45.4 vs 29.0%; P < 0.001). •  In addition, OAB patients had a higher use of medications with anti-muscarinic effects (39.6 vs 25.4%; P < 0.001). OAB patients were also more likely to have CV co-morbidities (57.6 vs 44.6%; P < 0.001). •  CNS co-morbidities were slightly more common in untreated (n= 8 106) than in treated (n= 33 334) OAB patients (47.2 vs 45.0%; P < 0.001). CV co-morbidities were higher in treated OAB patients (58.8 vs 53.7%; P < 0.001). •  In the additional separate analysis, which focused on all co-morbidities, patients with OAB had higher mean CCI and CDS scores than patients without OAB (CCI: 1.17 vs 1.11 [P < 0.001]; CDS: 2.95 vs 1.74 [P < 0.001]). •  After controlling for other covariates, the linear regressions (n= 22,544) showed that OAB patients had higher CCI and CDS than patients without OAB. •  Among OAB patients, CNS, CV and all co-morbidities were more prevalent than in non-OAB patients. •  Prior exposure to CNS medications was more prevalent in OAB patients who received anti-muscarinic treatment than in those who did not. •  Co-morbidities and concomitant medications affecting the CNS and the CV system should be taken into account when making the decision on the most appropriate OAB treatment option for each individual patient. © 2011 THE AUTHORS.

Dysfunctional cognitions may be associated with unhealthy eating behaviors seen in individuals with obesity. However, dysfunctional cognitions commonly occur in individuals with poor mental health independently of weight. We examined whether individuals with morbid obesity differed with regard to dysfunctional cognitions when compared to individuals of normal weight, when mental health status was controlled for. 111 participants-53 with morbid obesity and 58 of normal weight-were assessed with the Mini-Mental State Examination, Young Schema Questionnaire, Cognitive Distortions Questionnaire, Depression, Anxiety and Stress Scale, and a Demographic and Clinical Questionnaire. Participants with morbid obesity showed higher scores in one (insufficient self-control/self-discipline) of 15 early maladaptive schemas and in one (labeling) of 15 cognitive distortions compared to participants of normal weight. The difference between groups for insufficient self-control/self-discipline was not significant when mental health status was controlled for. Participants with morbid obesity showed more severe anxiety than participants of normal weight. Our findings did not show clinically meaningful differences in dysfunctional cognitions between participants with morbid obesity or of normal weight. Dysfunctional cognitions presented by individuals with morbid obesity are likely related to their individual mental health and not to their weight.

Morbidity differences between older members of private and statutory health insurance Germany have rarely been examined. Thus, we aimed at determining these differences in old age. This study used data from 2 follow-up waves with a 3-year interval from a population-based prospective cohort study (ESTHER study) in Saarland, Germany. Morbidity was assessed by participants' GPs using a generic instrument (Cumulative Illness Rating Scale for Geriatrics). The between estimator was used which exclusively quantifies inter-individual variation. Adjusting for sex and age, we investigated the association between health insurance and morbidity in the main model. In additional models, we adjusted incrementally for the effect of education, family status and income. Regression models not adjusting for income showed that members of private health insurance had a lower morbidity score than members of statutory health insurance. This effect is considerably lower in models adjusting for income, but remained statistically significant (except for men). Observed differences in morbidity between older members of private and statutory health insurance can partly be explained by income differences. Thus, our findings highlight the role of model specification in determining the relation between morbidity and health insurance. © Georg Thieme Verlag KG Stuttgart · New York.

Metabolic imaging biomarkers of postradiotherapy xerostomia.

Xerostomia is a major complication of head and neck radiotherapy (RT). Available xerostomia measures remain flawed. [(18)F]fluorodeoxyglucose-labeled positron emission tomography-computed tomography (FDG-PET-CT) is routinely used for staging and response assessment of head and neck cancer. We investigated quantitative measurement of parotid gland FDG uptake as a potential biomarker for post-RT xerostomia. Ninety-eight locally advanced head and neck cancer patients receiving definitive RT underwent baseline and post-RT FDG-PET-CT on a prospective imaging trial. A separate validation cohort of 14 patients underwent identical imaging while prospectively enrolled in a second trial collecting sialometry and patient-reported outcomes. Radiation dose and pre- and post-RT standard uptake values (SUVs) for all voxels contained within parotid gland ROI were deformably registered. Average whole-gland or voxel-by-voxel models incorporating parotid D(Met) (defined as the pretreatment parotid SUV weighted by dose) accurately predicted posttreatment changes in parotid FDG uptake (e.g., fractional parotid SUV). Fractional loss of parotid FDG uptake closely paralleled early parotid toxicity defined by posttreatment salivary output (p < 0.01) and Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer xerostomia scores (p < 0.01). In this pilot series, loss of parotid FDG uptake was strongly associated with acute clinical post-RT parotid toxicity. D(Met) may potentially be used to guide function-sparing treatment planning. Prospective validation of FDG-PET-CT as a convenient, quantifiable imaging biomarker of parotid function is warranted and ongoing. Copyright © 2012 Elsevier Inc. All rights reserved.

2013-10-01

The aim of the study was to systematically review and summarise existing evidence related to the perioperative morbidity associated with abdominal myomectomy in comparison with abdominal hysterectomy for uterine fibroids. A review of MEDLINE and EMBASE was carried out. The primary outcome was the major morbidity rate and secondary outcomes were uterine size, estimated blood loss, blood transfusion, operating time and duration of hospital stay. The results identified six observational studies including 1520 participants. All studies scored moderately on the N-OQA scale and were limited to a uterine size of up to 18 weeks. There was no significant difference in the rate of major morbidity (RR 0.94; 95% CI = 0.31, 2.81; p = 0.91) between the two operations. It was concluded that based on variable quality data from retrospective cohort studies, abdominal myomectomy and hysterectomy appear to have similar major morbidity rates for the uterine size up to 16-18 weeks. Well-designed trials with a standardised morbidity outcome and including uterine size greater than 18 weeks are required.

PAM50 Breast Cancer Subtyping by RT-qPCR and Concordance with Standard Clinical Molecular Markers

PubMed Central

2012-01-01

Background Many methodologies have been used in research to identify the “intrinsic” subtypes of breast cancer commonly known as Luminal A, Luminal B, HER2-Enriched (HER2-E) and Basal-like. The PAM50 gene set is often used for gene expression-based subtyping; however, surrogate subtyping using panels of immunohistochemical (IHC) markers are still widely used clinically. Discrepancies between these methods may lead to different treatment decisions. Methods We used the PAM50 RT-qPCR assay to expression profile 814 tumors from the GEICAM/9906 phase III clinical trial that enrolled women with locally advanced primary invasive breast cancer. All samples were scored at a single site by IHC for estrogen receptor (ER), progesterone receptor (PR), and Her2/neu (HER2) protein expression. Equivocal HER2 cases were confirmed by chromogenic in situ hybridization (CISH). Single gene scores by IHC/CISH were compared with RT-qPCR continuous gene expression values and “intrinsic” subtype assignment by the PAM50. High, medium, and low expression for ESR1, PGR, ERBB2, and proliferation were selected using quartile cut-points from the continuous RT-qPCR data across the PAM50 subtype assignments. Results ESR1, PGR, and ERBB2 gene expression had high agreement with established binary IHC cut-points (area under the curve (AUC) ≥ 0.9). Estrogen receptor positivity by IHC was strongly associated with Luminal (A and B) subtypes (92%), but only 75% of ER negative tumors were classified into the HER2-E and Basal-like subtypes. Luminal A tumors more frequently expressed PR than Luminal B (94% vs 74%) and Luminal A tumors were less likely to have high proliferation (11% vs 77%). Seventy-seven percent (30/39) of ER-/HER2+ tumors by IHC were classified as the HER2-E subtype. Triple negative tumors were mainly comprised of Basal-like (57%) and HER2-E (30%) subtypes. Single gene scoring for ESR1, PGR, and ERBB2 was more prognostic than the corresponding IHC markers as shown in a multivariate analysis. Conclusions The standard immunohistochemical panel for breast cancer (ER, PR, and HER2) does not adequately identify the PAM50 gene expression subtypes. Although there is high agreement between biomarker scoring by protein immunohistochemistry and gene expression, the gene expression determinations for ESR1 and ERBB2 status was more prognostic.

The primary objective of the present study was to evaluate the validity of the Groningen Frailty Indicator (GFI) in a sample of Dutch elderly persons participating in LifeLines, a large population-based cohort study. Additional aims were to assess differences between frail and non-frail elderly and examine which individual characteristics were associated with frailty. By December 2012, 5712 elderly persons were enrolled in LifeLines and complied with the inclusion criteria of the present study. Mann-Whitney U or Kruskal-Wallis tests were used to assess the variability of GFI-scores among elderly subgroups that differed in demographic characteristics, morbidity, obesity, and healthcare utilization. Within subgroups Kruskal-Wallis tests were also used to examine differences in GFI-scores across age groups. Multivariate logistic regression analyses were performed to assess associations between individual characteristics and frailty. The GFI discriminated between subgroups: statistically significantly higher GFI-median scores (interquartile range) were found in e.g. males (1 [0-2]), the oldest old (2 [1-3]), in elderly who were single (1 [0-2]), with lower socio economic status (1 [0-3]), with increasing co-morbidity (2 [1-3]), who were obese (2 [1-3]), and used more healthcare (2 [1-4]). Overall age had an independent and statistically significant association with GFI scores. Compared with the non-frail, frail elderly persons experienced statistically significantly more chronic stress and more social/psychological related problems. In the multivariate logistic regression model, psychological morbidity had the strongest association with frailty. The present study supports the construct validity of the GFI and provides an insight in the characteristics of (non)frail community-dwelling elderly persons participating in LifeLines.

Objective Quality of life (QoL) for women with gynecologic malignancies is predictive of chemotherapy related toxicity and overall survival but has not been studied in relation to surgical outcomes and hospital readmissions. Our goal was to evaluate the association between baseline, pre-operative QoL measures and 30-day post-operative morbidity and health resource utilization by gynecologic oncology patients. Methods We analyzed prospectively collected survey data from an institution-wide cohort study. Patients were enrolled from 8/2012 – 6/2013 and medical records data was abstracted (demographics, comorbid conditions, and operative outcomes). Responses from several validated health-related QoL instruments were collected. Bivariate tests and multivariable linear and logistic regression models were used to evaluate factors associated with QoL scores. Results Of 182 women with suspected gynecologic malignancies, 152 (84%) were surveyed pre-operatively and 148 (81%) underwent surgery. Uterine (94; 63.5%), ovarian (26; 17.5%), cervical (15; 10%), vulvar/vaginal (8; 5.4%), and other (5; 3.4%) cancers were represented. There were 37 (25%) cases of postoperative morbidity (PM), 18 (12%) unplanned ER visits, 9(6%) unplanned clinic visits, and 17 (11.5%) hospital readmissions(HR) within 30 days of surgery. On adjusted analysis, lower functional well-being scores resulted in increased odds of PM (OR 1.07, 95%CI 1.01-.1.21) and HR (OR 1.11, 95%CI 1.03-1.19). A subjective global assessment score was also strongly associated with HR (OR 1.89, 95%CI 1.14, 3.16). Conclusion Lower pre-operative QoL scores are significantly associated with post-operative morbidity and hospital readmission in gynecologic cancer patients. This relationship may be a novel indicator of operative risk. PMID:24726615

To compare psychosocial outcomes (follow-up related worries and satisfaction with follow-up related information and support) over 30 months of two alternative management policies for women with low-grade abnormal cervical cytology. Women aged 20-59 years with low-grade cytological abnormalities detected in the National Health Service Cervical Screening Programme were randomised to cytological surveillance or initial colposcopy. A total of 3399 women who completed psychosocial questionnaires at recruitment were invited to complete questionnaires at 12, 18, 24 and 30 months. Linear mixed models were used to investigate differences between arms in the two psychosocial outcomes. Each outcome had a maximum score of 100, and higher scores represented higher psychosocial morbidity. On average, over 30 months, women randomised to colposcopy scored 2.5 points (95%CI -3.6 to -1.3) lower for follow-up related worries than women randomised to cytological surveillance. Women in the colposcopy arm also scored significantly lower for follow-up related satisfaction with information and support (-2.4; -3.3 to -1.4) over 30 months. For both outcomes, the average difference between arms was greatest at 12th- and 18th-month time points. These differences remained when the analysis was stratified by post-school education. Women with low-grade cytology, irrespective of their management, have substantial initial psychosocial morbidity that reduces over time. Implementation of newer screening strategies, which include surveillance, such as primary HPV screening, need to consider the information and support provided to women. © 2016 The Authors.

Application of minimal access surgery in acute care surgery is limited due to various reasons. Laparoscopic omental patch repair (LOPR) for perforated peptic ulcer (PPU) surgery is safe and feasible but not widely implemented. We report our early experience of LOPR with emphasis on strict selection criteria. This is a descriptive study of all patients operated on for PPU at academic university-affiliated institutes from December 2010 to February 2012. All the patients who were operated on for LOPR were included as the study population and their records were studied. Perioperative outcomes, Boey score, Mannheim Peritonitis Index (MPI), and physiologic and operative severity scores for enumeration of mortality and morbidity (POSSUM) scores were calculated. All the data were tabulated in a Microsoft Excel spreadsheet and analyzed using Stata Version 8.x. (StataCorp, College Station, TX, USA). Fourteen patients had LOPR out of a total of 45 patients operated for the PPU. Mean age was 46 years (range 22−87 years). Twelve patients (86%) had a Boey score of 0 and all patients had MPI < 21 (mean MPI = 14). The predicted POSSUM morbidity and mortality were 36% and 7%, respectively. Mean ulcer size was 5 mm (range 2−10 mm), mean operating time was 100 minutes (range 70−123 minutes) and mean length of hospital stay was 4 days (range 3−6 days). There was no morbidity or mortality pertaining to LOPR. LOPR should be offered by acute care surgical teams when local expertise is available. This can optimize patient outcomes when strict selection criteria are applied. PMID:25692444

Popular predictive models for estimating morbidity probability after heart surgery are compared critically in a unitary framework. The study is divided into two parts. In the first part modelling techniques and intrinsic strengths and weaknesses of different approaches were discussed from a theoretical point of view. In this second part the performances of the same models are evaluated in an illustrative example. Eight models were developed: Bayes linear and quadratic models, k-nearest neighbour model, logistic regression model, Higgins and direct scoring systems and two feed-forward artificial neural networks with one and two layers. Cardiovascular, respiratory, neurological, renal, infectious and hemorrhagic complications were defined as morbidity. Training and testing sets each of 545 cases were used. The optimal set of predictors was chosen among a collection of 78 preoperative, intraoperative and postoperative variables by a stepwise procedure. Discrimination and calibration were evaluated by the area under the receiver operating characteristic curve and Hosmer-Lemeshow goodness-of-fit test, respectively. Scoring systems and the logistic regression model required the largest set of predictors, while Bayesian and k-nearest neighbour models were much more parsimonious. In testing data, all models showed acceptable discrimination capacities, however the Bayes quadratic model, using only three predictors, provided the best performance. All models showed satisfactory generalization ability: again the Bayes quadratic model exhibited the best generalization, while artificial neural networks and scoring systems gave the worst results. Finally, poor calibration was obtained when using scoring systems, k-nearest neighbour model and artificial neural networks, while Bayes (after recalibration) and logistic regression models gave adequate results. Although all the predictive models showed acceptable discrimination performance in the example considered, the Bayes and logistic regression models seemed better than the others, because they also had good generalization and calibration. The Bayes quadratic model seemed to be a convincing alternative to the much more usual Bayes linear and logistic regression models. It showed its capacity to identify a minimum core of predictors generally recognized as essential to pragmatically evaluate the risk of developing morbidity after heart surgery.

Despite a growing interest, few pediatric asthma questionnaires assess multiple dimensions of asthma morbidity, as recommended by national asthma guidelines, or use patient-reported outcomes. To evaluate a questionnaire that measures multiple dimensions of parent-reported asthma morbidity (Direction, Bother, and Risk). We administered the Pediatric Asthma Control and Communication Instrument (PACCI) and assessed asthma control (PACCI Control), quality of life, and lung function among children who presented for routine asthma care. The PACCI was evaluated for discriminative validity. A total of 317 children participated (mean age, 8.2 years; 58% boys; 44% African American). As parent-reported PACCI Direction changed from "better" to "worse," we observed poorer asthma control (P < .001), mean Pediatric Asthma Caregiver Quality of Life Questionnaire (PACQLQ) scores (P < .001), and FEV1% (P = .025). Linear regression showed that, for each change in PACCI Direction, the mean PACQLQ score decreased by -0.6 (95% CI, -0.8 to -0.4). As parent-reported PACCI Bother changed from "not bothered" to "very bothered," we observed poorer asthma control (P < .001) and lower mean PACQLQ scores (P < .001). Linear regression showed that, for each change in PACCI Bother category, the mean PACQLQ score decreased by -1.1 (95% CI, -1.3 to -0.9). Any reported PACCI Risk event (emergency department visit, hospitalization, or use of an oral corticosteroid) was associated with poorer asthma control (P < .05) and PACQLQ scores (P < .01). PACCI Direction, Bother, and Risk are valid measures of parent-reported outcomes and show good discriminative validity. The PACCI is a simple clinical tool to assess multiple dimensions of parent-reported asthma morbidity, in addition to risk and control.

Although the risk factors that contribute to postoperative complications are well recognized, prediction in the context of a particular patient is more difficult. We were interested in using a visual analog scale (VAS) to capture surgeons' prediction of the risk of a major complication and to examine whether this could be improved. The study was performed in 3 stages. In phase I, the surgeon assessed the risk of a major complication on a 100-mm VAS immediately before and after surgery. A quality control questionnaire was designed to check if the VAS was being scored as a linear scale. In phase II, a VAS with 6 subscales for different areas of clinical risk was introduced. In phase III, predictions were completed following the presentation of detailed feedback on the accuracy of prediction of complications. In total, 1295 predictions were made by 58 surgeons in 859 patients. Eight surgeons did not use a linear scale (6 logarithmic, 2 used 4 categories of risk). Surgeons made a meaningful prediction of major complications (preoperative median score 40 mm for complications v. 22 mm for no complication, P < 0.001; postoperative 46 mm v. 21 mm, P < 0.001). In phase I, the discrimination of prediction for preoperative (0.778), postoperative (0.810), and POSSUM (Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity) morbidity (0.750) prediction was similar. Although there was no improvement in prediction with a multidimensional VAS, there was a significant improvement in the discrimination of prediction after feedback (preoperative, 0.895; postoperative, 0.918). Awareness of different ways a VAS is scored is important when designing and interpreting studies. Clinical assessment of major complications by the surgeon was initially comparable to the prediction of the POSSUM morbidity score and improved significantly following the presentation of clinically relevant feedback. © The Author(s) 2016.

Surgery for prosthetic valve endocarditis (PVE) is associated with significant morbidity and mortality as well as with increased resource utilization and costs. For risk and cost reduction, an understanding of contributing factors and interrelations is essential. Out of 1080 heart valve procedures performed between January 2010 and December 2012, 41 patients underwent surgery for PVE. Complete economic data were available for 30 of them (study cohort). The patients' mean age was 64 ± 12 years (range 37-79 years), and 73% were men. The clinical course was reviewed and morbidity, mortality and costs as well as associations between them were analysed. The cost matrix for each individual patient was obtained from the Institute for the Hospital Remuneration System (InEK GmbH, Germany). The median follow-up was 2.6 years [interquartile range (IQR) 3.7 years; 100% complete]. Preoperative status was critical (EuroSCORE II >20%) in 43% of patients. Staphylococci were the most common infecting micro-organisms (27%). The operative mortality rate (≤30 days) was 17%. At 1 year, the overall survival rate was 71 ± 9%. At least one disease- or surgery-related complication affected 21 patients (early morbidity 70%), >1 complication affected 12 patients (40%). There was neither a recurrence of endocarditis, nor was a reoperation required. The mean total hospital costs were 42.6 ± 37.4 Thousand Euro (T€), median 25.7 T€, IQR 28.4 T€ and >100 T€ in 10% of cases. Intensive care unit/intermediate care (ICU/IMC) and operation accounted for 40.4 ± 18.6 and 25.7 ± 12.1% of costs, respectively. There was a significant correlation (Pearson's sample correlation coefficient) between total costs and duration of hospital stay (r = 0.83, P < 0.001) and between ICU/IMC costs and duration of ICU/IMC stay (r = 0.97, P < 0.001). The median daily hospital costs were 1.8 T€/day, but >2.4 T€/day in 25% of patients (upper quartile). The following pattern of associations was identified (P < 0.05). Early mortality was related to preoperative morbidity and postoperative renal failure. Early morbidity was associated with preoperative morbidity and urgency. Total costs were mainly explained by preoperative morbidity, postoperative morbidity and urgency. High EuroSCORE II, complex surgery, need for mechanical circulatory support as well as postoperative mortality and morbidity increased daily costs. The timely diagnosis and treatment of these patients must be a priority, as preoperative morbidity is the major contributor towards mortality, morbidity and costs after surgery for PVE. © The Author 2016.

Whether overweight or obese end stage renal disease (ESRD) patients are suitable for renal transplantation (RT) is often debated. The objective of this review and meta-analysis was to systematically investigate the outcome of low versus high BMI recipients after RT. Comprehensive searches were conducted in MEDLINE OvidSP, Web of Science, Google Scholar, Embase, and CENTRAL (the Cochrane Library 2014, issue 8). We reviewed four major guidelines that are available regarding (potential) RT recipients. The methodology was in accordance with the Cochrane Handbook for Systematic Reviews of Interventions and written based on the PRISMA statement. The quality assessment of studies was performed by using the GRADE tool. A meta-analysis was performed using Review Manager 5.3. Random-effects models were used. After identifying 5,526 studies addressing this topic, 56 studies were included. We extracted data for 37 outcome measures (including data of more than 209,000 RT recipients), of which 26 could be meta-analysed. The following outcome measures demonstrated significant differences in favour of low BMI (<30) recipients: mortality (RR = 1.52), delayed graft function (RR = 1.52), acute rejection (RR = 1.17), 1-, 2-, and 3-year graft survival (RR = 0.97, 0.95, and 0.97), 1-, 2-, and 3-year patient survival (RR = 0.99, 0.99, and 0.99), wound infection and dehiscence (RR = 3.13 and 4.85), NODAT (RR = 2.24), length of hospital stay (2.31 days), operation duration (0.77 hours), hypertension (RR = 1.35), and incisional hernia (RR = 2.72). However, patient survival expressed in hazard ratios was in significant favour of high BMI recipients. Differences in other outcome parameters were not significant. Several of the pooled outcome measurements show significant benefits for 'low' BMI (<30) recipients. Therefore, we postulate that ESRD patients with a BMI >30 preferably should lose weight prior to RT. If this cannot be achieved with common measures, in morbidly obese RT candidates, bariatric surgery could be considered.

Current means of measuring RT-induced fibrosis are subjective. We evaluated the DermaLab suction cup system to measure objectively skin deflection as a surrogate for fibrosis. Sixty-nine patients with E-STS were treated with limb-sparing surgery and 50-66 Grays (Gy) of RT. Using a "scleroderma" DermaLab Suction Cup, the skin stiffness was measured by two clinicians. The National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) scale, the Musculoskeletal Tumor Rating Scale (MSTS) and Toronto Extremity Salvage Score (TESS) questionnaires were completed for each patient. Levels of agreement between measurers were estimated using the Kappa (k) coefficient and the concordance correlation coefficient (CCC). All sixty-nine patients were included. The level of agreement between measurers for NCI-CTCAE grading was moderate (range k = 0.41-0.59). The CCC for the elasticity measurements were higher, with CCC = 0.82 for fibrotic skin and CCC 5 0.84 for normal skin. The elasticity measurements were significantly higher when MSTS scores were <30 and or TESS scores were <90. Suction Cup measurement of skin elasticity is more reproducible than CTCAE grading and shows promise in generating reproducible measurements for radiation-induced skin fibrosis. Furthermore, it correlates well with the MSTS and TESS.

Purpose The role of adjuvant chemotherapy (AC) or induction chemotherapy (IC) in the treatment of locally advanced nasopharyngeal carcinoma is controversial. The individual patient data from the Meta-Analysis of Chemotherapy in Nasopharynx Carcinoma database were used to compare all available treatments. Methods All randomized trials of radiotherapy (RT) with or without chemotherapy in nonmetastatic nasopharyngeal carcinoma were considered. Overall, 20 trials and 5,144 patients were included. Treatments were grouped into seven categories: RT alone (RT), IC followed by RT (IC-RT), RT followed by AC (RT-AC), IC followed by RT followed by AC (IC-RT-AC), concomitant chemoradiotherapy (CRT), IC followed by CRT (IC-CRT), and CRT followed by AC (CRT-AC). P-score was used to rank the treatments. Fixed- and random-effects frequentist network meta-analysis models were applied. Results The three treatments with the highest probability of benefit on overall survival (OS) were CRT-AC, followed by CRT and IC-CRT, with respective hazard ratios (HRs [95% CIs]) compared with RT alone of 0.65 (0.56 to 0.75), 0.77 (0.64 to 0.92), and 0.81 (0.63 to 1.04). HRs (95% CIs) of CRT-AC compared with CRT for OS, progression-free survival (PFS), locoregional control, and distant control (DC) were, respectively, 0.85 (0.68 to 1.05), 0.81 (0.66 to 0.98), 0.70 (0.48 to 1.02), and 0.87 (0.61 to 1.25). IC-CRT ranked second for PFS and the best for DC. CRT never ranked first. HRs of CRT compared with IC-CRT for OS, PFS, locoregional control, and DC were, respectively, 0.95 (0.72 to 1.25), 1.13 (0.88 to 1.46), 1.05 (0.70 to 1.59), and 1.55 (0.94 to 2.56). Regimens with more chemotherapy were associated with increased risk of acute toxicity. Conclusion The addition of AC to CRT achieved the highest survival benefit and consistent improvement for all end points. The addition of IC to CRT achieved the highest effect on DC. PMID:27918720

Purpose Cancer-Related Fatigue (CRF) negatively affects quality of life among cancer patients. This study seeks to evaluate the outcome and patient receptiveness of a brief counseling program based on National Cancer Institute (NCI) PDQ® information to manage CRF when integrated into Radiation Therapy (RT). Methods We conducted a prospective cohort study among patients undergoing non-palliative RT. Patients with stage I–III tumors and with Karnofsky score 60 or better were given a ten-minute behavioral counseling session during the first two weeks of RT. The Brief Fatigue Inventory (BFI) was administered at baseline/end of RT. Results Of 93 patients enrolled, 89% found the counseling useful and practical. By the end of RT, 59% reported increased exercise, 41.6% sought nutrition counseling, 72.7% prioritized daily activities, 74.4% took daytime naps, and 70.5% talked with other cancer patients. Regarding counseling, patients who had received chemotherapy prior to RT had no change in fatigue (−0.2), those who received RT alone had mild increase in fatigue (0.7, p=0.02), and those who received concurrent chemotherapy experienced a substantial increase in fatigue (3.0 to 5.2, p=0.05). Higher baseline fatigue and receipt of chemotherapy were predictive of worsened fatigue in a multivariate model (both p<0.01). Conclusion Our data suggests that brief behavioral counseling based on NCI guidelines is well accepted by patients showing an uptake in many activities to cope with CRF. Those who receive concurrent chemotherapy and with higher baseline fatigue are at risk for worsening fatigue despite of guideline-based therapy. PMID:29479490

Cine balanced steady-state free precession (SSFP), the preferred sequence for ventricular function, demands uninterrupted radio frequency (RF) excitation to maintain the steady-state during suspended respiration. This is difficult to accomplish in sedated children. In this work, we validate a respiratory triggered (RT) SSFP sequence that drives the magnetization to steady-state before commencing retrospectively cardiac gated cine acquisition in a sedated pediatric population. This prospective study was performed on 20 sedated children with congenital heart disease (8.6 ± 4 yrs). Identical imaging parameters were used for multiple number of signal averages (MN) and RT cine SSFP sequences covering both the ventricles in short-axis (SA) orientation. Image quality assessment and quantitative volumetric analysis was performed on the datasets by two blinded observers. One-sided Wilcoxon signed rank test and Box plot analysis were performed to compare the clinical scores. Bland-Altman (BA) analysis was performed on LV and RV volumes. Scan duration for SA stack using RT-SSFP (3.9 ± 0.8 min) was slightly shorter than MN-SSFP (4.6 ± 0.9 min) acquisitions. The endocardial edge definition was significantly better for RT than MN, blood to myocardial contrast was better for RT than MN without reaching statistical significance, and inter slice alignment was comparable. BA analysis indicates that the variability of volumetric indices between RT and MN is comparable to inter and intra-observer variability reported in the literature. The free breathing RT-SSFP sequence allows diagnostic images in sedated children with significantly better edge definition when compared to MN-SSFP, without any penalty for total scan time.

Recombinant Tissue Plasminogen Activator Induces Neurological Side Effects Independent on Thrombolysis in Mechanical Animal Models of Focal Cerebral Infarction: A Systematic Review and Meta-Analysis.

Recombinant tissue plasminogen activator (rtPA) is the only effective drug approved by US FDA to treat ischemic stroke, and it contains pleiotropic effects besides thrombolysis. We performed a meta-analysis to clarify effect of tissue plasminogen activator (tPA) on cerebral infarction besides its thrombolysis property in mechanical animal stroke. Relevant studies were identified by two reviewers after searching online databases, including Pubmed, Embase, and ScienceDirect, from 1979 to 2016. We identified 6, 65, 17, 12, 16, 12 and 13 comparisons reporting effect of endogenous tPA on infarction volume and effects of rtPA on infarction volume, blood-brain barrier, brain edema, intracerebral hemorrhage, neurological function and mortality rate in all 47 included studies. Standardized mean differences for continuous measures and risk ratio for dichotomous measures were calculated to assess the effects of endogenous tPA and rtPA on cerebral infarction in animals. The quality of included studies was assessed using the Stroke Therapy Academic Industry Roundtable score. Subgroup analysis, meta-regression and sensitivity analysis were performed to explore sources of heterogeneity. Funnel plot, Trim and Fill method and Egger's test were obtained to detect publication bias. We found that both endogenous tPA and rtPA had not enlarged infarction volume, or deteriorated neurological function. However, rtPA would disrupt blood-brain barrier, aggravate brain edema, induce intracerebral hemorrhage and increase mortality rate. This meta-analysis reveals rtPA can lead to neurological side effects besides thrombolysis in mechanical animal stroke, which may account for clinical exacerbation for stroke patients that do not achieve vascular recanalization with rtPA.

This article compared the effect of dietary weight loss administered alone (WL) or in combination with aerobic training (WL + AT) or resistance training (WL + RT) on health related quality of life, walking self-efficacy, stair climb self-efficacy, and satisfaction with physical function in older adults with cardiovascular disease or the metabolic syndrome. Participants (N = 249; M age  = 66.9) engaged in baseline assessments and were randomly assigned to one of three interventions, each including a 6-month intensive phase and a 12-month follow-up. Those in WL + AT and WL + RT engaged in 4 days of exercise training weekly. All participants engaged in weekly group behavioral weight loss sessions with a goal of 7-10% reduction in body weight. Participants in WL + AT and WL + RT reported better quality of life and satisfaction with physical function at 6- and 18-months relative to WL. At month 6, WL + AT reported greater walking self-efficacy relative to WL + RT and WL, and maintained higher scores compared to WL at month 18. WL + AT and WL + RT reported greater stair climbing efficacy at month 6, and WL + RT remained significantly greater than WL at month 18. The addition of either AT or RT to WL differentially improved HRQOL and key psychosocial outcomes associated with maintenance of physical activity and weight loss. This underscores the important role of exercise in WL for older adults, and suggests health care providers should give careful consideration to exercise mode when designing interventions.

Background and Purpose Recombinant tissue plasminogen activator (rtPA) is the only effective drug approved by US FDA to treat ischemic stroke, and it contains pleiotropic effects besides thrombolysis. We performed a meta-analysis to clarify effect of tissue plasminogen activator (tPA) on cerebral infarction besides its thrombolysis property in mechanical animal stroke. Methods Relevant studies were identified by two reviewers after searching online databases, including Pubmed, Embase, and ScienceDirect, from 1979 to 2016. We identified 6, 65, 17, 12, 16, 12 and 13 comparisons reporting effect of endogenous tPA on infarction volume and effects of rtPA on infarction volume, blood-brain barrier, brain edema, intracerebral hemorrhage, neurological function and mortality rate in all 47 included studies. Standardized mean differences for continuous measures and risk ratio for dichotomous measures were calculated to assess the effects of endogenous tPA and rtPA on cerebral infarction in animals. The quality of included studies was assessed using the Stroke Therapy Academic Industry Roundtable score. Subgroup analysis, meta-regression and sensitivity analysis were performed to explore sources of heterogeneity. Funnel plot, Trim and Fill method and Egger’s test were obtained to detect publication bias. Results We found that both endogenous tPA and rtPA had not enlarged infarction volume, or deteriorated neurological function. However, rtPA would disrupt blood-brain barrier, aggravate brain edema, induce intracerebral hemorrhage and increase mortality rate. Conclusions This meta-analysis reveals rtPA can lead to neurological side effects besides thrombolysis in mechanical animal stroke, which may account for clinical exacerbation for stroke patients that do not achieve vascular recanalization with rtPA.

Disparities in prostate cancer (PCa) morbidity and mortality occur across various populations. We investigated the sociodemographic correlates of treatment and disparities in the application of cure-intended (i.e., radical prostatectomy [RP], radiation therapy [RT]) treatment strategies in localized PCa among Texas residents diagnosed with PCa. We analyzed data from the Texas Cancer Registry on men diagnosed with stage T1 or T2 PCa between 2004 and 2009. Multinomial logistic regression analysis was used to explore independent associations between cure-intended treatment modalities and sociodemographic characteristics (age, race/ethnicity, socioeconomic status [SES], and geographic location (rural versus urban)) using patients who did not receive definitive treatment as comparison group. Of 46,971 patients with available treatment data, age-adjusted treatment rates were 39.1% RP, 30.7% RT, and 30.2% for all other non-curative modalities. Compared to patients under 60 years, those ≥60 were less likely to receive RP, patients between 60 and 80 years were more likely to undergo RT, while those 80 years or older were less likely. Non-Hispanic blacks (OR =0.55, 95% CI, 0.50-0.59) and Hispanics (OR = 0.68, 95%CI, 0.62-0.74) were less likely to receive RP compared with whites. Hispanics were significantly less likely to receive RT (OR = 0.78, 95%CI, 0.72-0.85) than blacks and whites. People of low SES were 35% (OR = 0.65, 95%CI, 0.60-0.69) and 15% (OR = 0.85, 95%CI, 0.79-0.90) less likely to receive RP and RT, respectively, compared with those of high SES. Rural-urban status was not associated with cure-intended treatment. Potential sociodemographic disparities exist in the application of cure-intended treatment in localized prostate cancer in Texas particularly in race/ethnicity and SES.

Pediatric Cushing's disease (CD) is rare and there are limited data on the long-term outcomes. We assessed CD recurrence, body composition, pituitary function and psychiatric comorbidity in a cohort of pediatric CD patients. Retrospective review of 21 CD patients, mean age at diagnosis 12.1 years (5.7-17.8), managed in our center between 1986 and 2010. Mean follow-up from definitive treatment was 10.6 years (2.9-27.2). Fifteen patients were in remission following transsphenoidal surgery (TSS) and 5 were in remission following TSS + external pituitary radiotherapy (RT). One patient underwent bilateral adrenalectomy (BA). CD recurrence occurred in 3 (14.3 %) patients: 2 at 2 and 6 years after TSS and 1 7.6 years post-RT. The BA patient developed Nelson's syndrome requiring pituitary RT 0.6 years post-surgery. Short-term growth hormone deficiency (GHD) was present in 14 patients (81 % patients tested) (11 following TSS and 3 after RT) and 4 (44 % of tested) had long-term GHD. Gonadotropin deficiency caused impaired pubertal development in 9 patients (43 %), 4 requiring sex steroid replacement post-puberty. Four patients (19 %) had more than one pituitary hormone deficiency, 3 after TSS and 1 post-RT. Five patients (24 %) had long-term psychiatric co-morbidities (cognitive dysfunction or mood disturbance). There were significant long-term improvements in growth, weight and bone density but not complete reversal to normal in all patients. The long-term consequences of the diagnosis and treatment of CD in children is broadly similar to that seen in adults, with recurrence of CD after successful treatment uncommon but still seen. Pituitary hormone deficiencies occurred in the majority of patients after remission, and assessment and appropriate treatment of GHD is essential. However, while many parameters improve, some children may still have mild but persistent defects.

Thrombolytic treatment with intravenous (IV) recombinant tissue plasminogen activator (rtPA; 0.90 mg/kg, with a maximum dose of 90 mg) has been recommended as the standard management for acute ischemic stroke (AIS) thrombolysis. However, the dose of IV rtPA in Asia remains controversial. This study was designed to verify the safety and efficacy of IV rtPA treatment for AIS with a lower dosage (0.90 mg/kg, with a maximum dose of 50 mg). Patients were divided into 3 dosage groups according to body weight (BW): group 1, <55 kg for 0.90 mg/kg; group 2, 55 to 67 kg for 0.75 to 0.90 mg/kg; and group 3, >67 kg for <0.75 mg/kg. The following data were collected: patient demographics, vascular risk factors, neuroimaging results, time of rtPA administration, National Institutes of Health Stroke Scale score before treatment and at 24 hours, and a modified Rankin Scale (mRS) score at 3 months. Eighty-three AIS patients who were of Han Chinese descent were included in the study. The baseline characteristics of the 3 dosage groups were well matched. In group 1 (BW <55 kg for 0.90 mg/kg; n = 19), 57.1% had a favorable outcome at 3 months, compared with 61.2% of patients in group 2 (BW 55-67 kg for 0.75-0.90 mg/kg; n = 33) and 51.5% in group 3 (BW >67 kg for <0.75 mg/kg; n = 31; P = .362). There were no significantly statistical differences in the incidence of symptomatic intracerebral hemorrhage and mortality rate. This IV rtPA regimen (0.90 mg/kg, with a maximum dose of 50 mg) not only shows sufficient favorable outcome in clinical practice in Chinese patients with AIS but also good health economic savings. This regimen could be suitable for many developing countries. Copyright © 2013 National Stroke Association. Published by Elsevier Inc. All rights reserved.

We assessed the relationship between insulin resistance, serum insulin-like growth factor 1 (IGF-1) levels, and common carotid intima-media thickness (CC-IMT) in morbidly obese young patients. A total of 249 patients (aged 37.9 ± 9.8 years, body mass index [BMI] 45.6 ± 8.3 kg/m(2)) were evaluated (metabolic tests, serum IGF-1 measurements, homeostasis model assessment-insulin resistance [HOMA-IR], and ultrasonographically assessed CC-IMT) in a research program for bariatric surgery candidates. After adjusting for age, gender, BMI, systolic blood pressure, uric acid, antihypertensive and lipid-lowering treatment, metabolic syndrome, and metabolic class, both HOMA-IR and IGF-1 z-score were significantly associated with CC-IMT. These results were confirmed in logistic regression analysis, in which age (β = 1.11, P = .001), gender (β = 3.19, P = .001), HOMA-IR (β = 1.221, P = .005), and IGF-1 z-score (β = 1.734, P = .009) were the only independent determinants of abnormal CC-IMT, presumably modulating the effect of the other risk factors included in the regression. Area under the receiver-operating characteristic curve for the model was 0.841 (confidence interval: 0.776-0.907; P < .001). In conclusion, in morbidly obese young adults, insulin resistance and IGF-1 z-score are significantly associated with CC-IMT, independent of other major cardiovascular risk factors. © The Author(s) 2015.

Measles continues to be a cause of morbidity and mortality in Côte d'Ivoire although the death rates are weak (2.4%). The monitoring and elimination programme of this disease require a laboratory confirmation testing by diverse methods of diagnosis needing diverse biological products. Serum is usually used for IgM detection. This study has therefore assessed the importance of the measles virus RNA detection from sera of measles suspected cases for confirmation of the case and determination of the genotype. A total of 45 sera tested were split into two groups according to the interval between the rash appearance and the day of blood collection: Group 1 (day 1 to day 3); group (2 day 4 to day 7). Four sera from Group 1 of the 45 (8.9 %) were positive by RT-PCR technique while 10 (22.2%) sera were positive for IgM anti- measles virus by ELISA test. RT-PCR and ELISA showed the same performance in group 1 with a positivity rate of 13.79 %. The B3 genotype was found. This result showed that the viral RNA can be detected in the serum but only from those sera collected the first 3 days after the rash appearance and could be used as palliative in case it is impossible to obtain other biological products.

Asthma management programs (AMP) may reduce costs and improve outcomes in patients with moderate to severe asthma. However, it is not known which personnel are best able to deliver such interventions and what settings are most effective. The purpose of this study was to compare the effects of an in-home AMP provided by respiratory therapists (RTs) to an AMP provided by nurses (RNs) and to usual care (UC) provided in physician offices or clinics. Subjects (age 18-64) who had been admitted to the emergency department (ED) or hospital for acute asthma exacerbation were randomized to three groups: AMP-RT, AMP-RN or UC. The AMP groups received five (5) weekly home visits to provide assessment and instruction; the UC group was instructed to return to their physician for routine follow-up. Outcomes assessed at 6 months included hospitalizations, in patient days, hospitalization cost, ED visits and cost, clinic visits, pulmonary function, symptoms, health related quality of life (HRQOL), asthma episode self-management score (AESM), environmental assessment, and patient satisfaction (PS). Variables were compared using ANOVA with a Neuman-Keuls follow-up for multiple comparisons using an intent-to-treat approach. Upon enrollment, (n = 159) there were no differences (p > .05) between groups for age, gender, pulmonary function or HRQOL (SF-36 and St. Georges Respiratory Questionnaire - SGRQ). At 6 months, both AMP groups (AMP-RN n = 54; AMP-RT n = 46) had significantly fewer (p < 0.05) hospitalizations and in-patient days, lower hospitalization costs, and greater HRQOL physical component summary change scores (PCS) and PS than UC (n = 59). AMP-RT also had greater PEFR, SGRQ Total and SGRQ Symptoms change scores when compared to UC and significantly better AESM and PS scores as compared to AMP-RN and UC. An in-home asthma management program can be effectively delivered by respiratory therapists and may reduce hospitalizations, in-patient days, cost and improve measures of HRQOL and PS in a population prone to asthma exacerbation.

Traumatic brain injury (TBI) remains one of the leading causes of mortality and morbidity, especially in the young population. To predict the outcome of TBI, Marshall, and Rotterdam–CT Scan based scoring was mostly used. As many studies showed conflicting results regarding of the usage of both scoring, this study aims to determine the correlation between Rotterdam and Marshall scoring system with outcome in 30 days and found correlation among them. In 120 subjects with TBI that admitted to Adam Malik General Hospital, we found a significant association of both scorings with the 30-day Glasgow Outcome Score. Therefore, we recommend the use of Marshall and Rotterdam CT Score in initial assessment as a good predictor for patients with TBI.

The purpose of this study was to assess the quality of life (QOL) and voice handicap in a sample of disease-free patients who had been treated at our center with radiotherapy (RT) or surgery for early glottic cancer. QOL and voice handicap were assessed using the European Organisation for Research and Treatment of Cancer (EORTC) questionnaires Quality of Life Questionnaire-Core 30-questions (QLQ-C30) and Quality of Life Questionnaire-Head and Neck 35-questions (QLQ-H&N35) and the Voice Handicap Index (VHI). Ninety-one patients completed the questionnaires. Fifty-nine patients (65%) were treated with RT and 32 (35%) with surgery. QOL scores for the sample recorded, moderate limitations in 6 areas, and more than moderate limitations (>30 of 100) in 2 areas. Significant differences were found in emotional functioning (88.5 vs 76.6) and social contact (4.6 vs 12.1) on the EORTC questionnaires and on the VHI (6.1 vs 12.8), which favored the RT group. In this cross-sectional study, voice quality, emotional functioning, and social contact were better in the RT group. © 2014 Wiley Periodicals, Inc.

Work-related stress, psychological disorders and burnout are common occupational disorders affecting UK doctors. To date, there are no studies looking at these psychosocial morbidities amongst ENT surgeons worldwide. The General Health Questionnaire-12 (GHQ-12) and abbreviated Maslach Burnout Inventory (aMBI) were incorporated into a questionnaire on occupational diseases amongst ENT surgeons and distributed to the entire membership of ENT-UK. The survey study also acquired demographic data on grade of respondent, years of experience in ENT and subspecialty interest. We received 108 (8.1% response rate) appropriately filled GHQ-12 and 121 (9.0% response rate) aMBI questionnaires. 61 respondents (56.5%) on the GHQ-12 were at high risk of developing stress and psychological morbidity and 35 (28.9%) had high enough aMBI scores to suggested burnout. When comparing scores of both GHQ-12 and aMBI with grade of respondent, years of experience in ENT and subspecialty, statistical difference was only found on the risk of stress and psychiatric disorders amongst paediatric ENT surgeons (7 high risk vs 0 low risk, p = 0.02), however the number of these respondents was small (7 in total). Both questionnaires had been validated for use within our population. We found high incidence rates of stress and psychological morbidity (56.5%) and a burnout prevalence rate of 28.9% amongst our responding cohort of UK Oto-rhino-laryngologists. No meaningful differences were found between stress, psychological morbidity and burnout with grade of ENT surgeon, years of experience in ENT and subspecialty within ENT.

Despite the prevalence of fear of cancer recurrence (FCR), understanding of factors underlying clinically significant FCR is limited. This study examined factors associated with greater FCR morbidity, according to a cognitive processing model, in cancer survivors who screened positively for clinically significant FCR seeking psychological treatment through the ConquerFear trial. Participants had completed treatment for breast, colorectal or melanoma cancer 2 months to 5 years previously and scored ≥ 13/36 on the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). Hierarchical regression analyses examined associations between demographic, medical and psychological variables, namely metacognitions (MCQ-30), post-traumatic stress symptoms (IES-R) and FCR (FCRI total score). Two hundred and ten (95%) of the 222 cancer survivors who consented to the ConquerFear trial completed the baseline questionnaire. Participants were predominantly (89%) breast cancer survivors. The final regression model accounted for 68% of the variance in FCR (demographic and medical variables 13%, metacognitions 26%, post-traumatic stress symptoms 28%). Negative metacognitive beliefs about worry and intrusive post-traumatic stress symptoms were significant individual correlates of FCR, but negative beliefs about worry did not significantly moderate the impact of intrusions on FCR morbidity. Results provide partial support for the cognitive processing model of FCR. Psychological factors were found to play an important role in FCR morbidity after controlling for demographic/medical factors. More intrusive thoughts and negative beliefs about worry were strong independent predictors of FCR morbidity. Cancer survivors with clinically significant FCR may benefit from assessment for intrusive thoughts and metacognitions and delivery of trauma- and/or metacognitive-based interventions accordingly.

Pressure sores and hip fractures.

Development of pressure sores during hospital admission causes morbidity and distress to the patient, increases strain on nursing resources, delaying discharge and possibly increasing mortality. A hip fracture in elderly patients is a known high-risk factor for development of pressure sores. We aimed to determine the current incidence of pressure sores and identify those factors which were associated with an increased risk of pressure sores. We retrospectively analysed prospectively collected data of 4654 consecutive patients admitted to a single unit. One hundred and seventy-eight (3.8%) of our patients developed pressure sores. Patient factors that increased the risk of pressure sores were increased age, diabetes mellitus, a lower mental test score, a lower mobility score, a higher ASA score, lower admission haemoglobin and an intra-operative drop in blood pressure. The risk was higher in patients with an extracapsular neck of femur fracture and patients with an increased time interval between admission to hospital and surgery. Our studies indicate that while co-morbidities constitute a substantial risk in an elderly population, the increase in incidence of pressure sores can be reduced by minimising delays to surgery.

The purpose of this study was to characterize the collagen component of repair tissue (RT) of the talus after autologous matrix-induced chondrogenesis (AMIC) using quantitative T2 and diffusion-weighted imaging. Mean T2 values and diffusion coefficients of AMIC-RT and normal cartilage of the talus of 25 patients with posttraumatic osteochondral lesions and AMIC repair were compared in a cross-sectional design using partially spoiled steady-state free precession (pSSFP) for T2 quantification, and diffusion-weighted double-echo steady-state (dwDESS) for diffusion measurement. RT and cartilage were graded with modified Noyes and MOCART scores on morphological sequences. An association between follow-up interval and quantitative MRI measures was assessed using multivariate regression, after stratifying the cohort according to time interval between surgery and MRI. Mean T2 of the AMIC-RT and cartilage were 43.1 ms and 39.1 ms, respectively (p = 0.26). Mean diffusivity of the RT (1.76 μm(2)/ms) was significantly higher compared to normal cartilage (1.46 μm(2)/ms) (p = 0.0092). No correlation was found between morphological and quantitative parameters. RT diffusivity was lowest in the subgroup with follow-up >28 months (p = 0.027). Compared to T2-mapping, dwDESS demonstrated greater sensitivity in detecting differences in the collagen matrix between AMIC-RT and cartilage. Decreased diffusivity in patients with longer follow-up times may indicate an increased matrix organization of RT. • MRI is used to assess morphology of the repair tissue during follow-up. • Quantitative MRI allows an estimation of biochemical properties of the repair tissue. • Differences between repair tissue and cartilage were more significant with dwDESS than T2 mapping.

We describe four solid-organ transplant recipients with donor-derived West Nile virus (WNV) infection (encephalitis 3, asymptomatic 1) from a common donor residing in a region of increased WNV activity. All four transplant recipients had molecular evidence of WNV infection in their serum and/or cerebrospinal fluid (CSF) by reverse transcription polymerase chain reaction (RT-PCR) testing. Serum from the organ donor was positive for WNV IgM but negative for WNV RNA, whereas his lymph node and spleen tissues tested positive for WNV by RT-PCR. Combination therapy included intravenous immunoglobulin (4 cases), interferon (3 cases), fresh frozen plasma with WNV IgG (2 cases), and ribavirin (1 case). Two of the four transplant recipients survived. Review of the 20 published cases of organ-derived WNV infection found that this infection is associated with a high incidence of neuroinvasive disease (70%) and severe morbidity and mortality (30%). Median time to onset of symptomatic WNV infection was 13 days after transplantation (range 5–37 days). Initial unexplained fever unresponsive to antibiotic therapy followed by rapid onset of neurologic deficits was the most common clinical presentation. Confirmation of infection was made by testing serum and CSF for both WNV RNA by RT-PCR and WNV IgM by serological assays. Treatment usually included supportive care, reduction of immunosuppression, and frequent intravenous immunoglobulin. The often negative results for WNV by current RT-PCR and serological assays and the absence of clinical signs of acute infection in donors contribute to the sporadic occurrence of donor-derived WNV infection. Potential organ donors should be assessed for unexplained fever and neurological symptoms, particularly if they reside in areas of increased WNV activity. PMID:24827763

Urothelial carcinoma (UC) causes substantial morbidity and mortality worldwide. However, the molecular mechanisms underlying urothelial cancer development and tumor progression are still largely unknown. Using informatics analysis, we identified Sh3gl2 (endophilin A1) as a bladder urothelium-enriched transcript. The gene encoding Sh3gl2 is located on chromosome 9p, a region frequently altered in UC. Sh3gl2 is known to regulate endocytosis of receptor tyrosine kinases implicated in oncogenesis, such as the epidermal growth factor receptor (EGFR) and c-Met. However, its role in UC pathogenesis is unknown. Informatics analysis of expression profiles as well as immunohistochemical staining of tissue microarrays revealed Sh3gl2 expression to be decreased in UC specimens compared to nontumor tissues. Loss of Sh3gl2 was associated with increasing tumor grade and with muscle invasion, which is a reliable predictor of metastatic disease and cancer-derived mortality. Sh3gl2 expression was undetectable in 19 of 20 human UC cell lines but preserved in the low-grade cell line RT4. Stable silencing of Sh3gl2 in RT4 cells by RNA interference 1) enhanced proliferation and colony formation in vitro, 2) inhibited EGF-induced EGFR internalization and increased EGFR activation, 3) stimulated phosphorylation of Src family kinases and STAT3, and 4) promoted growth of RT4 xenografts in subrenal capsule tissue recombination experiments. Conversely, forced re-expression of Sh3gl2 in T24 cells and silenced RT4 clones attenuated oncogenic behaviors, including growth and migration. Together, these findings identify loss of Sh3gl2 as a frequent event in UC development that promotes disease progression. PMID:23814487

The objective of this study was to investigate the safety, tolerability and preliminary efficacy of radiotherapy plus cetuximab in high risk CSCC patients. Patients with high-risk CSCC diagnosed between 2006 and 2013 were analyzed. Patients were divided into two groups: radiotherapy alone versus radiotherapy plus cetuximab. Among 68 patients meeting study criteria, we identified 29 treated with cetuximab plus RT and 39 with RT alone. Primary analysis examined disease-free and overall survival, freedom from local and distant recurrence in the propensity score matched cohort. Propensity score analysis was performed with weighted factors including: Charlson Comorbidity Index score, age. KPS, primary location, T and N stage, recurrent status, margin status, LVSI, PNI and grade. Toxicity was assessed using the CTCAE v4.0. Median follow-up for living patients was 30 months. Patients in the cetuximab group were more likely to have advanced N stage, positive margins and recurrent disease. After propensity score matching the groups were well balanced. Six patients experienced ≥ grade 3 acute toxicity in the cetuximab group. The 1-year, 2-year and 5-year progression free survival (PFS) for patients in the cetuximab group were 86%, 72% and 66%, respectively. The 1-year, 2-year and 5-year overall survival (OS) for patients in the cetuximab group was 98%, 80% and 80%, respectively. Although limited by small numbers, the combination of cetuximab and radiotherapy in CSCC appears well tolerated there were more long-term survivors and less distant metastasis in the cetuximab group. These promising finding warrant further studies. Copyright © 2018 Elsevier Ltd. All rights reserved.

Surgical trainee association with operative outcomes is controversial. Studies are conflicting, possibly due to insufficient control of confounding variables such as operative time, case complexity, and heterogeneous patient populations. As operative complications worsen long-term outcomes in oncologic patients, understanding effect of trainee involvement during laparoscopic colectomy for cancer is of utmost importance. Here, we hypothesized that resident involvement was associated with worsened 30-day mortality and 30-day overall morbidity in this patient population. Patients undergoing laparoscopic colectomy for oncologic diagnosis from 2005 to 2012 were assessed using the American College of Surgeons National Surgical Quality Improvement Program dataset. Propensity score matching accounted for demographics, comorbidities, case complexity, and operative time. Attending only cases were compared to junior, middle, chief resident, and fellow level cohorts to assess primary outcomes of 30-day mortality and 30-day overall morbidity. A total of 13,211 patients met inclusion criteria, with 4075 (30.8%) cases lacking trainee involvement and 9136 (69.2%) involving a trainee. Following propensity matching, junior (PGY 1-2) and middle level (PGY 3-4) resident involvement was not associated with worsened outcomes. Chief (PGY 5) resident involvement was associated with worsened 30-day overall morbidity (15.5 vs. 18.6%, p = 0.01). Fellow (PGY > 5) involvement was associated with worsened 30-day overall morbidity (16.0 vs. 21.0%, p < 0.001), serious morbidity (9.3 vs. 13.5%, p < 0.001), minor morbidity (9.8 vs. 13.1%, p = 0.002), and surgical site infection (7.9 vs. 10.5%, p = 0.006). No differences were seen in 30-day mortality for any resident level. Following propensity-matched analysis of cancer patients undergoing laparoscopic colectomy, chief residents, and fellows were associated with worsened operative outcomes compared to attending along cases, while junior and mid-level resident outcomes were no different. Further study is necessary to determine what effect the PGY surgical trainee level has on post-operative morbidity in cancer patients undergoing laparoscopic colectomy in the context of multiple collinear factors.

The International Classification of Functioning, Disability, and Health (ICF) provides a framework for measuring functioning and disability based on a biopsychosocial model. The aim of this study was to develop comprehensive and brief ICF core sets for morbid obesity for disability assessment in Taiwan. Observational Other Twenty-nine multidisciplinary experts of ICF METHODS: The questionnaire contained 112 obesity-relevant and second-level ICF categories. Using a 5-point Likert scale, the participants rated the significance of the effects of each category on the heath status of people with obesity. Correlation between an individual's score and the average score of the group indicated consensus. The categories were selected for the comprehensive core set for obesity if more than 50% of the experts rated them as "important" in the third round of the Delphi exercise, and for the brief core set if more than 80% of the experts rated them "very important." Twenty-nine experts participated in the study. These included 18 physicians, 4 dieticians, 3 physical therapists, 2 nurses, and 2 ICF experts. The comprehensive core set for morbid obesity contained 61 categories. Of these, 26 categories were from the component body function, 8 were from body structure, 18 were from activities and participation, and 9 were from environmental factors. The brief core set for obesity disability contained 29 categories. Of these, 19 categories were from the component body function, 3 were from body structure, 6 were from activities and participation, and one was from environmental factors. The comprehensive and brief ICF core sets provide comprehensive information on the health effects of morbid obesity and concise information for clinical practice. Comprehensive and brief core sets were created after three rounds of Delphi technique. Further validation study of these core sets by applying to patients with morbid obesity is needed. The comprehensive ICF core set for morbid obesity provides comprehensive information on the health effects of morbid obesity; the brief core set can provide concise information for clinical practice.

Background and Aim. The aim of this study was to investigate the effects of demographic characteristics, biochemical parameters, amount of blood transfusion, and trauma scores on morbidity in patients with solid organ injury following trauma. Material and Method. One hundred nine patients with solid organ injury due to abdominal trauma during January 2005 and October 2015 were examined retrospectively in the General Surgery Department of Dicle University Medical Faculty. Patients' age, gender, trauma interval time, vital status (heart rate, arterial tension, and respiratory rate), hematocrit (HCT) value, serum area aminotransferase (ALT) and aspartate aminotransferase (AST) values, presence of free abdominal fluid in USG, trauma mechanism, extra-abdominal system injuries, injured solid organs and their number, degree of injury in abdominal CT, number of blood transfusions, duration of hospital stay, time of operation (for those undergoing operation), trauma scores (ISS, RTS, Glasgow coma scale, and TRISS), and causes of morbidity and mortality were examined. In posttraumatic follow-up period, intra-abdominal hematoma infection, emboli, catheter infection, and deep vein thrombosis were monitored as factors of morbidity. Results. One hundred nine patients were followed up and treated due to isolated solid organ injury following abdominal trauma. There were 81 males (74.3%) and 28 females (25.7%), and the mean age was 37.6 ± 18.28 (15–78) years. When examining the mechanism of abdominal trauma in patients, the following results were obtained: 58 (53.3%) traffic accidents (22 out-vehicle and 36 in-vehicle), 27 (24.7%) falling from a height, 14 (12.9%) assaults, 5 (4.5%) sharp object injuries, and 5 (4.5%) gunshot injuries. When evaluating 69 liver injuries scaled by CT the following was detected: 14 (20.3%) of grade I, 32 (46.4%) of grade II, 22 (31.8%) of grade III, and 1 (1.5%) of grade IV. In 63 spleen injuries scaled by CT the following was present: grade I in 21 (33.3%), grade II in 27 (42.9%), grade III in 11 (17.5%), and grade IV in 4 (6.3%). The mean length of hospital stay after trauma was 6.46 days in the medically followed patients. This ratio was 8.13 days in 22 patients with morbidity and 5.98 days in 78 patients without morbidity. There was a morbidity in 22 (22%) patients medically followed after trauma. In this study, nonoperative treatment was observed to be performed safely in solid organ injuries after trauma in case of absence of hemodynamic stability and peritoneal irritation. It has been emphasized that injury of both liver and spleen (p < 0.01), high respiratory rate (p < 0.01), trauma scores (GKS, ISS, RTS) (p < 0.0001), and elevation of ALT AST values (p < 0.01) are stimulants for morbidity that may occur during follow-up. Conclusion. Medical follow-up can be considered in patients with high grade injuries similar to patients with low-grade solid organ injury after trauma. The injury of both liver and spleen, high respiratory rate, high GCS and ISS, low RTS, and elevation of ALT AST values were found to increase morbidity again in the follow-up of these patients.

To report the oncological and functional outcomes of hemi salvage high-intensity focused ultrasound (HSH) in patients with unilateral radiorecurrent prostate cancer. Between 2009 and 2012, 48 patients were prospectively enrolled in two European centres. Inclusion criteria were biochemical recurrence (BCR) after primary radiotherapy (RT), positive magnetic resonance imaging and ≥1 positive biopsy in only one lobe. BCR was defined using Phoenix criteria (a rise by ≥2 ng/mL above the nadir prostate specific antigen [PSA] level). The following schemes and criteria for functional outcomes were used: Ingelman-Sundberg score using International Continence Society (ICS) questionnaire (A and B), International prostate symptom score (IPSS), International Index of Erectile Function-5 (IIEF-5) points, the European Organisation for the Research and Treatment of Cancer (EORTC) quality of life questionnaires (QLQ C-30). HSH was performed under spinal or general anaesthesia using the Ablatherm® Integrated Imaging device. Patients with obstructive voiding symptoms at the time of treatment underwent an endoscopic bladder neck resection or incision during the same anaesthesia to prevent the risk of postoperative obstruction. After HSH the mean (sd) PSA nadir was 0.69 (0.83) ng/mL at a median (interquartile range) follow-up of 16.3 (10.5-24.5) months. Disease progression occurred in 16/48 (33%). Of these, four had local recurrence in the untreated lobe and four bilaterally, six developed metastases, and two had rising PSA levels without local recurrence or radiological confirmed metastasis. Progression-free survival rates at 12, 18, and 24 months were 83%, 64%, and 52%. Severe incontinence occurred in four of the 48 patients (8%), eight (17%) required one pad a day, and 36/48 (75%) were pad-free. The ICS questionnaire showed a mean (sd) deterioration from 0.7 (2.0) to 2.3 (4.5) for scores A and 0.6 (1.4) to 1.6 (3.0) for B. The mean (sd) IPSS and erectile function (IIEF-5) scores decreased from a mean (sd) of 7.01 (5.6) to 8.6 (5.1) and from 11.2 (8.6) to 7.0 (5.8), respectively. The mean (sd) EORTC QLC-30 scores before and after HSH were 35.7 (8.6) vs 36.8 (8.6). HSH is a feasible therapeutic option in patients with unilateral radiorecurrent prostate cancer, which offers limited urinary and rectal morbidity, and preserves health-related quality of life. © 2013 The Authors.

To determine whether adjuvant radiation therapy (RT) is associated with adverse patient-reported outcomes and surgical complications 1 year after skin-sparing mastectomy and immediate autologous free flap reconstruction for breast cancer. We compared 24 domains of patient-reported outcome measures 1 year after autologous reconstruction between patients who received adjuvant RT and those who did not. A total of 125 patients who underwent surgery between 2012 and 2015 at our institution were included from the Mastectomy Reconstruction Outcomes Consortium study database. Adjusted multivariate models were created incorporating RT technical data, age, cancer stage, estrogen receptor, chemotherapy, breast size, body mass index, and income to determine whether RT was associated with outcomes. At 1 year after surgery, European Organisation for Research and Treatment of Cancer (EORTC) Breast Cancer-Specific Quality of Life Questionnaire breast symptoms were significantly greater in 64 patients who received RT (8-point difference on 100-point ordinal scale, P<.0001) versus 61 who did not receive RT in univariate and multivariate models. EORTC arm symptoms (20-point difference on 100-point ordinal scale, P=.0200) differed on univariate analysis but not on multivariate analysis. All other outcomes-including Numerical Pain Rating Scale, BREAST-Q (Post-operative Reconstruction Module), Patient-Report Outcomes Measurement Information System Profile 29, McGill Pain Questionnaire-Short Form (MPQ-SF) score, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire-were not statistically different between groups. Surgical complications were uncommon and did not differ by treatment. RT to the neo-breast compared with no RT following immediate autologous free flap reconstruction for breast cancer is well tolerated at 1 year following surgery despite patients undergoing RT also having a higher cancer stage and more intensive surgical and systemic treatment. Neo-breast symptoms are more common in patients receiving RT by the EORTC Breast Cancer-Specific Quality of Life Questionnaire but not by the BREAST-Q. Patient-reported results at 1 year after surgery suggest RT following immediate autologous free flap breast reconstruction is well tolerated. Copyright © 2017 Elsevier Inc. All rights reserved.

Thrombolysis with Intravenous Tissue Plasminogen Activator (rt-PA) Predicts Favorable Discharge Disposition in Patients with Acute Ischemic Stroke

Background and Purpose Acute ischemic stroke patients receiving IV tissue plasminogen activator (rt-PA) within 3 hours of symptom onset are 30% more likely to have minimal disability at three months. During hospitalization, short-term disability is subjectively measured by discharge disposition, whether to home, Inpatient Rehabilitation (IR), Skilled Nursing Facility (SNF) or Subacute Care (Sub). There are no studies assessing the role of rt-PA use as a predictor of post-stroke disposition. Methods Retrospective analysis of all ischemic stroke patients admitted to the University of Texas Houston Medical School (UTHMS) Stroke Service between Jan 2004 and Oct 2009. Baseline demographics and National Institute of Health Stroke Scale (NIHSS) score were collected. Cerebrovascular disease risk factors were used for risk stratification. Results Home vs. IR, SNF, Sub Of 2225 acute ischemic stroke patients, 1019 were discharged home, 1206 to another level of care. Patients who received rt-PA therapy were 1.9 times more likely to be discharged home (P = <0.0001; OR 1.945, 95% CI 1.538 to 2.459). IR vs. SNF, Sub / SNF vs. Sub Of 1206 acute ischemic stroke patients, 719 patients were discharged to acute IR, 371 were discharged to SNF, 116 to Sub. There were no differences in disposition between patients who received rt-PA therapy. Conclusions Stroke patients who receive IV rt-PA for acute ischemic stroke are more 1.9 times more likely to be discharged directly home after hospitalization. This study is limited by its retrospective nature and the undetermined role of psychosocial factors related to discharge. PMID:21293014

Dysfunctional cognitions may be associated with unhealthy eating behaviors seen in individuals with obesity. However, dysfunctional cognitions commonly occur in individuals with poor mental health independently of weight. We examined whether individuals with morbid obesity differed with regard to dysfunctional cognitions when compared to individuals of normal weight, when mental health status was controlled for. 111 participants—53 with morbid obesity and 58 of normal weight—were assessed with the Mini-Mental State Examination, Young Schema Questionnaire, Cognitive Distortions Questionnaire, Depression, Anxiety and Stress Scale, and a Demographic and Clinical Questionnaire. Participants with morbid obesity showed higher scores in one (insufficient self-control/self-discipline) of 15 early maladaptive schemas and in one (labeling) of 15 cognitive distortions compared to participants of normal weight. The difference between groups for insufficient self-control/self-discipline was not significant when mental health status was controlled for. Participants with morbid obesity showed more severe anxiety than participants of normal weight. Our findings did not show clinically meaningful differences in dysfunctional cognitions between participants with morbid obesity or of normal weight. Dysfunctional cognitions presented by individuals with morbid obesity are likely related to their individual mental health and not to their weight. PMID:28264484

To develop a mathematical model utilizing more readily available measures than stimulation tests that identifies brain tumor survivors with high likelihood of abnormal growth hormone secretion after radiotherapy (RT), to avoid late recognition and a consequent delay in growth hormone replacement therapy. We analyzed 191 prospectively collected post-RT evaluations of peak growth hormone level (arginine tolerance/levodopa stimulation test), serum insulin-like growth factor 1 (IGF-1), IGF-binding protein 3, height, weight, growth velocity, and body mass index in 106 children and adolescents treated for ependymoma (n=72), low-grade glioma (n=28) or craniopharyngioma (n=6), who had normal growth hormone levels before RT. Normal level in this study was defined as the peak growth hormone response to the stimulation test≥7 ng/mL. Independent predictor variables identified by multivariate logistic regression with high statistical significance (p<0.0001) included IGF-1 z score, weight z score, and hypothalamic dose. The developed predictive model demonstrated a strong discriminatory power with an area under the receiver operating characteristic curve of 0.883. At a potential cutoff point of probability of 0.3 the sensitivity was 80% and specificity 78%. Without unpleasant and expensive frequent stimulation tests, our model provides a quantitative approach to closely follow the growth hormone secretory capacity of brain tumor survivors. It allows identification of high-risk children for subsequent confirmatory tests and in-depth workup for diagnosis of growth hormone deficiency. Copyright © 2012 Elsevier Inc. All rights reserved.

Norovirus continues to pose a significant burden on cruise ships, causing an average of 27 confirmed outbreaks annually over the past 5 years. In January 2009, the report of a suspected norovirus outbreak among passengers on a cruise ship prompted an investigation. A retrospective cohort study among passengers was conducted on board the ship. Questionnaires about health care-seeking behaviors, hygiene practices, and possible norovirus exposures were placed in every cabin. Stool samples from several ill passengers were tested for norovirus by quantitative reverse-transcriptase polymerase chain reaction (RT-qPCR) and confirmed by sequence analysis. Of 1842 passengers, 1532 (83.2%) returned questionnaires, and 236 (15.4% of participants) met the case definition. Of these, 95 (40%) did not report to the infirmary. Case passengers were significantly more likely to have an ill cabin mate (relative risk [RR] = 3.0; P < .01) and to have witnessed vomiting during boarding (RR = 2.8; P = .01). Over 90% of all passengers reported increased hand hygiene practices following the outbreak; 38% of ill passengers and 11% of well passengers decreased participation in public activities. Of 14 samples tested, 12 were positive for norovirus by RT-qPCR; 5 of these were confirmed by sequence analysis and typed as GII.4 Minerva. Person-to-person transmission, including an incident of public vomiting during boarding, likely contributed to this high morbidity outbreak. Infirmary surveillance detected only 60% of acute gastroenteritis (AGE) cases involved in this outbreak. Adjustments to outbreak reporting thresholds may be needed to account for incomplete voluntary AGE reporting and to more rapidly implement control measures.

the incidence of epistaxis has increased secondary to increased life expectancy and morbidities. This study sought to assess the knowledge, practice and opinion relating to adequacy of training of advanced nurse practitioners (ANPs) and staff nurses (SNs) in the emergency department. a national survey was distributed over an 8-week period; this included a 3-point scoring system based on the National Institute for Health and Care Excellence Clinical Knowledge Summaries guidance on epistaxis management to assess overall performance. analysis included 109 ANPs and 101 SNs; 12% of ANPs achieved the maximum score, 40% scored 2, 25% scored 1, and 23% scored 0, while 14% of SNs achieved the maximum score, 24% scored 2, 29% scored 1, and 32% scored 0. Overall 88% of respondents advocated further training. significant deficits in knowledge regarding epistaxis management were highlighted. Further training could help to empower patients in basic first aid measures, subsequently reducing admissions rates.

To evaluate the hypothesis that assigning grades to magnetic resonance imaging (MRI) findings of suspected placenta accreta will correlate with hemorrhagic outcomes. We chose a single-center, retrospective, observational design. Nulliparous or multiparous women who had antenatal placental MRI performed at a tertiary level academic hospital were included. Cases with antenatal placental MRI were included and compared with cases without MRI performed. Two radiologists assigned a probability score for accreta to each study. Estimated blood loss and transfusion requirements were compared among groups by the Kruskal-Wallis H test. Thirty-five cases had placental MRI performed. MRI performance was associated with higher blood loss compared with the non-MRI group (2600 [1400-4500]mL vs 900[600-1500]mL, P<.001). There was no difference in estimated blood loss (P=.31) or transfusion (P=.57) among the MRI probability groups. In cases of suspected placenta accreta, probability scores for antenatal placental MRI may not be associated with increasing degrees of hemorrhage. Continued research is warranted to determine the effectiveness of assigning probability scores for antenatal accreta imaging studies, combined with clinical indices of suspicion, in assisting with antenatal multidisciplinary team planning for operative management of this morbid condition.

Most patients presenting with acutely perforated duodenal ulcer undergo operation, but conservative treatment may be indicated when an ulcer has spontaneously sealed with minimal/localised peritoneal irritation or when the patient's premorbid performance status is poor. We retrospectively reviewed our experience with operative and conservative management of perforated duodenal ulcers over a 10-year period and analysed outcome according to American Society of Anesthesiologists (ASA) score. The records of all patients presenting with perforated duodenal ulcer to the Department of Surgery, Mayo General Hospital, between January 1998 and December 2007 were reviewed. Age, gender, co-morbidity, ASA-score, clinical presentation, mode of management, operative procedures, morbidity and mortality were considered. Of 76 patients included, 48 (44 operative, 4 conservative) were ASA I-III, with no mortality irrespective of treatment. Amongst 28 patients with ASA-score IV/V, mortality was 54.5% (6/11) following operative management and 52.9% (9/17) with conservative management. In patients with a perforated duodenal ulcer and ASA-score I-III, postoperative outcome is uniformly favourable. We recommend these patients have repair with peritoneal lavage performed, routinely followed postoperatively by empirical triple therapy. Given that mortality is equivalent between ASA IV/V patients whether managed operatively or conservatively, we suggest that both management options are equally justifiable.

Co-morbidities of epilepsy have not been well explored in the elderly. Herein, we examined mental status, mood, and sleep in elderly patients with epilepsy, compared to age and gender matched community controls without epilepsy from the Einstein Aging Study. Testing included a mental status test, the Blessed Information Memory and Concentration (BIMC) test; Prime-MD Patient Health Questionnaire (PHQ) Depression and Anxiety Modules; and Medical Outcomes Study Sleep Scale. Persons with epilepsy (n=31) had higher mean BIMC scores than controls (n=31, BIMC 6.3 vs.1.2; p<0.0001). Mean PHQ Depression scores were higher for cases than controls indicating more depressive symptoms (4.2 vs. 0.8; p=0.006); six cases (18%) and no controls met screening criteria for depression. Mean PHQ Anxiety scores were also higher for cases than controls (3.7 vs. 0.0; p=0.001). Cases demonstrated poorer sleep scores in the categories of somnolence (p=0.009) and shortness of breath/headache (p=0.021). Thus, co-morbidities of epilepsy in this elderly population included decreased mental status, a higher prevalence of depression and anxiety, and poorer sleep health when compared to age mates without epilepsy. Mental status impairment was not related to anti-epileptic medication or mood disturbance. Further investigation will explore these associations prospectively. PMID:19189862

Purpose A comparatively high prevalence of co-morbidities among African-American/Blacks (AA/B) has been implicated in disparate survival in breast cancer. There is a scarcity of data, however, if this effect persists when accounting for the adverse triple-negative breast cancer (TNBC) subtype which occurs at three-fold the rate in AA/B compared to white breast cancer patients. Methods We reviewed charts of 214 white and 202 AA/B breast cancer patients in the NCI-SEER Connecticut Tumor Registry who were diagnosed in 2000-07. We employed the Charlson Co-Morbidity Index (CCI), a weighted 17-item tool to predict risk of death in cancer populations. Cox Survival Analyses estimated hazard ratios (HR) for all-cause mortality in relation to TNBC and CCI adjusting for clinicopathological factors. Results Among patients with SEER-Local Stage, TNBC increased the risk of death (HR=2.18, 95% CI 1.14-4.16), which was attenuated when the CCI score was added to the model (Adj. HR=1.50, 95% CI 0.74-3.01). Conversely, the adverse impact of the CCI score persisted when controlling for TNBC (Adj. HR=1.49, 95% CI 1.29-1.71; per one point increase). Similar patterns were observed in SEER-Regional Stage but estimated HRs were lower. AA/B patients with a CCI score of ≥3 had a significantly higher risk of death compared to AA/B patients without comorbidities (Adj. HR=5.65, 95% CI 2.90-11.02). A lower and non-significant effect was observed for whites with a CCI of ≥3 (Adj. HR=1.90, 95% CI 0.68-5.29). Conclusions Co-morbidities at diagnosis increase risk of death independent of TNBC, and AA/B patients may be disproportionately at risk. PMID:27000206

Cancer and its treatment have an influence on health-related quality of life (HRQOL). Normative data could help to interpret HRQOL among cancer patients. Our aim was to generate longitudinal normative data based on sex, age and morbidity for the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire. The QLQ-C30 and the Self-administered Comorbidity Questionnaire were administered to a representative panel of the Dutch-speaking population in the Netherlands in 2009 (n = 1743), 2010 (n = 2050), 2011 (n = 2040), 2012 (n = 2194) and 2013 (n = 2333). Regarding sex, at baseline, women scored statistically significant and clinically relevant worse on fatigue, pain and insomnia compared to men. Regarding age groups and sex, HRQoL was lower among the older age groups in men and women. For men, at baseline, significant and clinically relevant age differences were found on physical, role and cognitive functioning, global QOL scale, fatigue, pain and dyspnea. The change over 5 years was larger for older age groups. For women, at baseline, significant and clinically relevant age differences were found on physical functioning, role functioning, nausea/vomiting, pain, dyspnea and insomnia. Those without self-reported morbidities reported a better HRQoL compared to those with morbidities. Among those who completed five assessments, the summary scale scores were stable over time, were higher in men than in women, and higher in younger compared to older age groups. Although HRQoL remains relatively stable over time, HRQoL data needs to be interpreted with care as many confounding factors can have an impact on HRQOL. Our data (which is freely available) can aid in the interpretation of QLQ-C30 scores and can help increase our understanding of the influence of age, sex, time and morbid conditions on HRQoL among cancer patients.

The aims are to assess respiration-related quality of life using the St. George Respiratory Questionnaire and determine its influencing factors among patients with silicosis in China. The incidence of silicosis had an increasing trend in recent years in developing countries. Although the majority of patients with silicosis are in therapy routinely, the patients' quality of life has been impaired because silicosis cannot be cured. The study on quality of life of patients with silicosis is few, and clinical physicians have difficulty in planning to promote quality of life of patients with silicosis according to the current health situation. A cross-sectional design was used for this study. A survey was performed on patients with silicosis by face-to-face interview in the Shenyang No. 9 Hospital in China. The St. George Respiratory Questionnaire was used to assess respiration-related quality of life. In all 208 enrolled patients with silicosis, symptoms, activity and impacts scores were 56·02, 56·46 and 52·33, respectively. Lower impacts scores were found comparing with symptoms and activity ones. Patient age was associated with an expected decrease in respiration-related quality of life. Patients with longer duration of exposure had higher total scores of the St. George Respiratory Questionnaire, indicating worse quality of life. Patients with more co-morbidities reported worse quality of life. Patients with silicosis were found relatively moderate respiration-related quality of life. Shortening dust exposure, decreasing the number of co-morbidity and controlling the occurrence of pulmonary tuberculosis could improve respiration-related quality of life. As indicated by the results of this study, the number of co-morbidity negatively impact the quality of life of patients with silicosis. Clinical physicians and nurses should pay close attention to the co-morbidity to promote quality of life of patients with silicosis according to the current health situation. © 2011 Blackwell Publishing Ltd.

The decision whether to treat older adults with advanced cancer with standard therapy (ST) or reduced therapy (RT) is complicated by heterogeneity in aging. We assessed the potential utility of the chemotherapy toxicity risk score (CTRS) [J Clin Oncol 2011;29:3457-3465] for treatment decisions in older adults. This was a prospective observational study of patients aged ≥65 years receiving first-line chemotherapy for advanced cancer for which combination chemotherapy is the standard of care. Patients were categorized as high risk (CTRS ≥10), for whom RT (dose-reduced combination or single-agent chemotherapy) is deemed appropriate, or nonhigh risk (CTRS <10), for whom ST is deemed appropriate for toxicity. The primary objective was to estimate the agreement in chemotherapy choice (ST vs. RT) between the treating physician and the CTRS using a κ statistic. Fifty-eight patients (median age, 71 years) were enrolled. Thirty-eight patients received ST (21 had CTRS <10, and 17 had CTRS ≥10), and 20 patients received RT (12 had CTRS ≥10, and 8 had CTRS <10), with minimal agreement in chemotherapy choice (κ = 0.14; 95% CI, -0.10 to 0.38). Grade 3-4 toxicity and hospitalization occurred in 60% and 27% of 55 patients with follow-up data, respectively. Among patients receiving ST, patients with CTRS ≥10 had a higher incidence of toxicity (88% vs. 40%, p  = .006) and hospitalization (50% vs. 15%, p  = .03) than those with CTRS <10. Older patients with cancer with a high CTRS who receive combination chemotherapy have an exceedingly high rate of severe toxicity and hospitalization. The potential utility of the chemotherapy toxicity risk score (CTRS) in old adults with advanced solid tumors receiving first-line chemotherapy was assessed. Little agreement was found between chemotherapy treatment decisions based on the clinical impression versus what was recommended based on the CTRS. Among patients treated with standard-dose combination chemotherapy, patients with CTRS ≥10 had a very high incidence of grade 3-4 toxicities and hospitalization, which was significantly greater than that of patients with a low CTRS (<10). These findings suggest that the addition of CTRS to the clinical impression has a potential to improve treatment decisions. © AlphaMed Press 2018.

The aim of this study was to validate the Total Activity Measure, a brief questionnaire, to measure physical activity in an older adult population with heart disease. Two versions of the Total Activity Measure were administered twice, 7 days apart. The Total Activity Measure 1 asked respondents for the frequency and average duration of bouts of physical activity at three different intensity levels per week, whereas the Total Activity Measure 2 asked respondents for the total time spent in activity at each activity level per week. Questionnaire accuracy was studied in 62 men and 15 women aged 47-84 years, by repeatability and comparison of both administrations of the Total Activity Measure 1 and Total Activity Measure 2 with 7-day RT3 accelerometer data. Seventy-three adults (58 men, 15 women) were used for all statistical analyses. Intraclass correlation coefficients for the Total Activity Measure 1 and Total Activity Measure 2 total activity scores (metabolic equivalent per minute) were r=0.73 (95% confidence intervals, 0.56-0.83) and r=0.82 (95% confidence intervals, 0.71-0.88), respectively. Correlations between the Total Activity Measure 1 and RT3 accelerometer for total activity score (metabolic equivalent per minute) were significant, r=0.26 at time 1 and r=0.27 at time 2 for moderate intensity activities. Correlations between the Total Activity Measure 2 and RT3 accelerometer for total activity score (metabolic equivalent per minute) were also significant, r=0.38 at time 1 and r=0.36 at time 2, r=0.31 at time 2 for strenuous intensity activities and r=0.29 at time 1 and r=0.25 at time 2 for moderate intensity activities. Participants overestimated the amount of physical activity on both questionnaires as compared with the RT3 accelerometer. The Total Activity Measure 2 was reasonably accurate in assessing total and moderate intensity activity over a 7-day period and demonstrated good test-retest reliability. The Total Activity Measure 1 was less accurate. The Total Activity Measure 2 is a suitable measure of total or moderate intensity physical activity for surveys and audits in an adult cardiac population.

Brief interventions such as Screening, a single session of Brief Intervention, and Referral to Treatment (SBIRT) have shown mixed effectiveness in primary care. However, there are indications that multi-session brief interventions may demonstrate more consistently positive outcomes, and perhaps a more intensive approach would be of benefit in addressing substance use in primary care. This study compared the effectiveness of SBIRT with a single BI session (BI/RT) to a multi-session brief-treatment intervention (BI/RT+) in primary care. We also developed easy-to-use, evidence-based materials to assist clinicians in delivering these interventions. This study was conducted in three Federally Qualified Healthcare Centers (FQHCs). A total of 10,935 patients were screened, and 600 individuals were recruited. The sample was primarily Black/African American (82 %) with a mean age of 40. Patients who attended a healthcare appointment were screened for substance use via the AUDIT and DAST. Patients were eligible for the study if they scored 8 or higher on the AUDIT, were using only marijuana and scored 2 or higher on the DAST, or were using other illicit drugs and scored 1 or higher on the DAST. Participants were randomly assigned to receive one-session BI/RT, or two to six sessions of brief intervention that incorporated elements of motivational enhancement therapy and cognitive-behavioral therapy (BI/RT+). Both interventions were delivered by behavioral health consultants at the FQHCs. Participants completed follow-up assessments every 3 months for 1 year. Primary outcome variables included substance use treatment sessions attended and days of substance use. Secondary outcomes included measures of health, employment, legal, and psychiatric functioning and HIV risk behaviors. Additionally, we will conduct an economic evaluation examining cost-effectiveness and will analyze outcomes from a process evaluation examining patient and provider experiences. The ability of brief interventions to impact substance use has great potential, but research findings have been mixed. By conducting a large-scale randomized controlled trial in real-world health centers, this study will answer important questions about the effectiveness of expanded BIs for patients who screen positive for risky substance use in primary care.

To compare three methods of measuring multiple morbidity according to the use of health resources (cost of care) in primary healthcare (PHC). Retrospective study using computerized medical records. Thirteen PHC teams in Catalonia (Spain). Assigned patients requiring care in 2008. The socio-demographic variables were co-morbidity and costs. Methods of comparison were: a) Combined Comorbidity Index (CCI): an index itself was developed from the scores of acute and chronic episodes, b) Charlson Index (ChI), and c) Adjusted Clinical Groups case-mix: resource use bands (RUB). The cost model was constructed by differentiating between fixed (operational) and variable costs. 3 multiple lineal regression models were developed to assess the explanatory power of each measurement of co-morbidity which were compared from the determination coefficient (R(2)), p< .05. The study included 227,235 patients. The mean unit of cost was €654.2. The CCI explained an R(2)=50.4%, the ChI an R(2)=29.2% and BUR an R(2)=39.7% of the variability of the cost. The behaviour of the ICC is acceptable, albeit with low scores (1 to 3 points), showing inconclusive results. The CCI may be a simple method of predicting PHC costs in routine clinical practice. If confirmed, these results will allow improvements in the comparison of the case-mix. Copyright © 2011 Elsevier España, S.L. All rights reserved.

Greater cognitive ability in childhood is associated with increased longevity, and speedier reaction time (RT) might account for much of this linkage. Greater bodily symmetry is linked to both higher cognitive test scores and faster RTs. It is possible, then, that differences in bodily system integrity indexed by symmetry may underlie the…

Although there are over 40,000 licensed radiological technologists (RTs) in Korea, job competency standards have yet to be defined. This study aims to clarify the job competency of Korean RTs. A task force team of 11 professional RTs were recruited in order to analyze the job competency of domestic and international RTs. A draft for the job competency of Korean RTs was prepared. A survey was then conducted sampling RTs and the attitudes of their competencies were recorded from May 21 to July 30, 2016. We identified five modules of professionalism, patient management, health and safety, operation of equipment, and procedure management and 131 detailed job competencies for RTs in Korea. "Health and safety" had the highest average score and "professionalism" had the lowest average score for both job performance and importance. The content validity ratios for the 131 subcompetencies were mostly valid. Establishment of standard guidelines for RT job competency for multidisciplinary healthcare at medical institutions may be possible based on our results, which will help educators of RT training institutions to clarify their training and education.

The combination of robot-assisted therapy (RT) and a modified form of constraint-induced therapy (mCIT) shows promise for improving motor function of patients with stroke. However, whether the changes of motor control strategies are concomitant with the improvements in motor function after combination of RT and mCIT (RT + mCIT) is unclear. This study investigated the effects of the sequential combination of RT + mCIT compared with RT alone on the strategies of motor control measured by kinematic analysis and on motor function and daily performance measured by clinical scales. The study enrolled 34 patients with chronic stroke. The data were derived from part of a single-blinded randomized controlled trial. Participants in the RT + mCIT and RT groups received 20 therapy sessions (90 to 105 min/day, 5 days for 4 weeks). Patients in the RT + mCIT group received 10 RT sessions for first 2 weeks and 10 mCIT sessions for the next 2 weeks. The Bi-Manu-Track was used in RT sessions to provide bilateral practice of wrist and forearm movements. The primary outcome was kinematic variables in a task of reaching to press a desk bell. Secondary outcomes included scores on the Wolf Motor Function Test, Functional Independence Measure, and Nottingham Extended Activities of Daily Living. All outcome measures were administered before and after intervention. RT + mCIT and RT demonstrated different benefits on motor control strategies. RT + mCIT uniquely improved motor control strategies by reducing shoulder abduction, increasing elbow extension, and decreasing trunk compensatory movement during the reaching task. Motor function and quality of the affected limb was improved, and patients achieved greater independence in instrumental activities of daily living. Force generation at movement initiation was improved in the patients who received RT. A combination of RT and mCIT could be an effective approach to improve stroke rehabilitation outcomes, achieving better motor control strategies, motor function, and functional independence of instrumental activities of daily living.

Purpose We have previously reported that radiotherapy (RT) added to androgen-deprivation therapy (ADT) improves survival in men with locally advanced prostate cancer. Here, we report the prespecified final analysis of this randomized trial. Patients and Methods NCIC Clinical Trials Group PR.3/Medical Research Council PR07/Intergroup T94-0110 was a randomized controlled trial of patients with locally advanced prostate cancer. Patients with T3-4, N0/Nx, M0 prostate cancer or T1-2 disease with either prostate-specific antigen (PSA) of more than 40 μg/L or PSA of 20 to 40 μg/L plus Gleason score of 8 to 10 were randomly assigned to lifelong ADT alone or to ADT+RT. The RT dose was 64 to 69 Gy in 35 to 39 fractions to the prostate and pelvis or prostate alone. Overall survival was compared using a log-rank test stratified for prespecified variables. Results One thousand two hundred five patients were randomly assigned between 1995 and 2005, 602 to ADT alone and 603 to ADT+RT. At a median follow-up time of 8 years, 465 patients had died, including 199 patients from prostate cancer. Overall survival was significantly improved in the patients allocated to ADT+RT (hazard ratio [HR], 0.70; 95% CI, 0.57 to 0.85; P < .001). Deaths from prostate cancer were significantly reduced by the addition of RT to ADT (HR, 0.46; 95% CI, 0.34 to 0.61; P < .001). Patients on ADT+RT reported a higher frequency of adverse events related to bowel toxicity, but only two of 589 patients had grade 3 or greater diarrhea at 24 months after RT. Conclusion This analysis demonstrates that the previously reported benefit in survival is maintained at a median follow-up of 8 years and firmly establishes the role of RT in the treatment of men with locally advanced prostate cancer.

Zaorsky, Nicholas G., E-mail: nicholaszaorsky@gmail.com; Shaikh, Talha; Handorf, Elizabeth

Purpose: The purposes of this study were to assess the exposure that medical students (MSs) have to radiation oncology (RO) during the course of their medical school career, as evidenced by 2 time points in current medical training (ie, first vs fourth year; MS1s and MS4s, respectively) and to assess the knowledge of MS1s, MS4s, and primary care physicians (PCPs) about the appropriateness of RT in cancer management in comparison with RO attendings. Methods: We developed and beta tested an electronic survey divided into 3 parts: RO job descriptions, appropriateness of RT, and toxicities of RT. The surveys were distributedmore » to 7 medical schools in the United States. A concordance of >90% (either yes or no) among RO attendings in an answer was necessary to determine the correct answer and to compare with other subgroups using a χ{sup 2} test (P<.05 was significant). Results: The overall response rate for ROs, MS1s, MS4s, and PCPs was 26%; n (22 + 315 + 404 + 43)/3004. RT misconceptions decreased with increasing level of training. More than 1 of 10 MSs did not believe that RT alone could cure cancer. Emergent oncologic conditions for RT (eg, spinal cord compression, superior vena cava syndrome) could not be identified by >1 of 5 respondents. Multiple nontoxicities of RT (eg, emitting low-level radiation from the treatment site) were incorrectly identified as toxicities by >1 of 5 respondents. MS4s/PCPs with an RO rotation in medical school had improved scores in all prompts. Conclusions: Although MS knowledge of general RT principles improves from the first to the fourth year, a large knowledge gap still exists between MSs, current PCPs, and ROs. Some basic misconceptions of RT persist among a minority of MSs and PCPs. We recommend implementing formal education in RO fundamentals during the core curriculum of medical school.« less

Thyroid Patient Salivary Radioiodine Transit and Dysfunction Assessment Using Chewing Gums.

PubMed

Okkalides, Demetrios

2016-11-01

Radiation-induced salivary gland dysfunction is the most frequent side-effect of I-131 thyroid therapy. Here, a novel saliva sampling method with ordinary chewing gums administered to the patients at appropriate time intervals post-treatment (TIPT) was used to relate this effect to chewing gum saliva activity (CGSA) content. Saliva samples were acquired after the oral administration of prescribed I-131 activity (radioactivity administered [RA]) to 19 differentiated thyroid cancer (DTC) and 16 hyperthyroidism patients of the radioisotope unit (RIU) during 2014 and 2015. The error of this saliva collecting process was found to be 1.2%-2.05%, and so, the method was considered satisfactory. For each patient, the CGSA was plotted against the TIPT producing a curve, R(t). On this, two functions were fitted: a linear on the first few rising data points and a gamma variate over the peak of the R(t). From these, several parameters related to the radioactivity oral transit were calculated and the total radioactivity administered (TRA) during all past treatments of each patient was obtained from RIU records. The patients were asked to report any swelling, dry mouth, taste-smell change, or pain and were graded as a morbidity score (MS) describing the quality of life of each. The peak radioactivity in the saliva samples, R max , was found to be proportional to RA and was plotted against the CGSA extrapolated at 24 and 36 hours. The linear fits produced were used to estimate the salivary glands' activity average effective half-life (16.3 hours). The MS of DTC patients was found to depend linearly both on R max and TRA (MS = 0.0032 × R max - 0.7107 and MS = 0.1862 × TRA +0.66, respectively). Both lines were used to extrapolate symptom thresholds. The measurement of R max in DTC patients proved very useful for individualized radiation protection, and the dependence of MS on TRA should be used when additional treatments are considered for repeat DTC patients.

We aimed to determine the impact of clinical practice guidelines (CPG) on rates of radiation oncologist (RO) referral, androgen-deprivation therapy (ADT), radiation therapy (RT), and radical prostatectomy (RP) in patients with high-risk prostate cancer (HR-PCa). All men >18 years, diagnosed with PCa in 2005 and 2012 were identified from the Alberta Cancer Registry. Patient age, aggregated clinical risk group (ACRG) score, Gleason score (GS), pre-treatment prostate-specific antigen (PSA), RO referral, and treatment received were extracted from electronic medical records. Logistic regression modelling was used to examine associations between RO referral rates and relevant factors. HR-PCa was diagnosed in 261 of 1792 patients in 2005 and 435 of 2148 in 2012. Median age and ACRG scores were similar in both years (p>0.05). The rate of patients with PSA >20 were 67% and 57% in 2005 and 2012, respectively (p=0.004). GS ≤6 was found in 13% vs. 5% of patients, GS 7 in 27% vs. 24%, and GS ≥8 in 59% vs. 71% in 2005 and 2012, respectively (p<0.001). In 2005, RO referral rate was 68% compared to 56% in 2012 (p=0.001), use of RT + ADT was 53% compared to 32% (p<0.001), and RP rate was 9% vs. 17% (p=0.002). On regression analysis, older age, 2012 year of diagnosis and higher PSA were associated with decreased RO referral rates (odds ratios [OR] 0.49, 95% confidence interval [CI] 0.39-0.61; OR 0.51, 95% CI 0.34-0.76; and OR 0.64, 95% CI 0.39-0.61), respectively [p<0.001]). Since CPG creation in 2005, RO referral rates and ADT + RT use declined and RP rates increased, which demonstrates a need to improve adherence to CPG in the HR-PCa population.

Current diagnostic ECG criteria of left ventricular hypertrophy in obese patients are still lacking. To assess the current ECG diagnostic criteria of LVH, and to validate our previously proposed criteria in a group of patients with morbid obesity. A group of consecutive 429 obese patients (MOP) with BMI of at least 35 kg/m 2 (mean age 38.6 ± 8.9 years, BMI 48.7 ± 9.0 kg/m 2 ; 323 females, 106 males) were included. The diagnosis of LVH in MOPs was confirmed only by RaVL of 7.5 mm, Cornell index of 12.5 mm; Cornell index × QRS duration of 1,125 mm × ms and Romhilt-Estes score of 1. None of the criteria proposed to date is appropriate in super-morbidly obese patients. Our study confirmed that none of the currently used voltage-based ECG criteria is appropriate for diagnosing LVH in morbidly obese patients.

Emergency surgery for perforated peptic ulcer (PPU) is associated with significant morbidity and mortality. Accurate and early risk stratification is important. The primary aim of this study is to validate the various existing MRPMs and secondary aim is to audit our experience of managing PPU. 332 patients who underwent emergency surgery for PPU at a single intuition from January 2008 to December 2012 were studied. Clinical and operative details were collected. Four MRPMs: American Society of Anesthesiology (ASA) score, Boey's score, Mannheim peritonitis index (MPI) and Peptic ulcer perforation (PULP) score were validated. Median age was 54.7 years (range 17-109 years) with male predominance (82.5%). 61.7% presented within 24 h of onset of abdominal pain. Median length of stay was 7 days (range 2-137 days). Intra-abdominal collection, leakage, re-operation and 30-day mortality rates were 8.1%, 2.1%, 1.2% and 7.2% respectively. All the four MRPMs predicted intra-abdominal collection and mortality; however, only MPI predicted leak (p = 0.01) and re-operation (p = 0.02) rates. The area under curve for predicting mortality was 75%, 72%, 77.2% and 75% for ASA score, Boey's score, MPI and PULP score respectively. Emergency surgery for PPU has low morbidity and mortality in our experience. MPI is the only scoring system which predicts all - intra-abdominal collection, leak, reoperation and mortality. All four MRPMs had a similar and fair accuracy to predict mortality, however due to geographic and demographic diversity and inherent weaknesses of exiting MRPMs, quest for development of an ideal model should continue.

Three prospective randomised trials reported discordant findings regarding the impact of adjuvant radiation therapy (aRT) versus observation for metastasis-free survival (MFS) and overall survival (OS) among patients with pT3N0 prostate cancer treated with radical prostatectomy (RP). None of these trials systematically included patients who underwent early salvage radiation therapy (esRT). To test the hypothesis that aRT was associated with better cancer control and survival compared with observation followed by esRT. Using a multi-institutional cohort from seven tertiary referral centres, we retrospectively identified 510 pT3pN0 patients with undetectable prostate-specific antigen (PSA) after RP between 1996 and 2009. Patients were stratified into two groups: aRT (group 1) versus observation followed by esRT in case of PSA relapse (group 2). Specifically, esRT was administered at a PSA level ≤0.5ng/ml. We compared aRT versus observation followed by esRT. The evaluated outcomes were MFS and OS. Multivariable Cox regression analyses tested the association between groups (aRT vs observation followed by esRT) and oncologic outcomes. Covariates consisted of pathologic stage (pT3a vs pT3b or higher), pathologic Gleason score (≤6, 7, or ≥8), surgical margin status (negative vs positive), and year of surgery. An interaction with groups and baseline patient risk was tested for the hypothesis that the impact of aRT versus observation followed by esRT was different by pathologic characteristics. The nonparametric curve fitting method was used to explore graphically the relationship between MFS and OS at 8 yr and baseline patient risk (derived from the multivariable analysis). Overall, 243 patients (48%) underwent aRT, and 267 (52%) underwent initial observation. Within the latter group, 141 patients experienced PSA relapse and received esRT. Median follow-up after RP was 94 mo (interquartile range [IQR]: 53-126) and 92 mo (IQR: 70-136), respectively (p=0.2). MFS (92% vs 91%; p=0.9) and OS (89% vs 92%; p=0.9) at 8 yr after surgery were not significantly different between the two groups. These results were confirmed in multivariable analysis, in which observation followed by esRT was not associated with a significantly higher risk of distant metastasis (hazard ratio [HR]: 1.35; p=0.4) and overall mortality (HR: 1.39; p=0.4) compared with aRT. Using the nonparametric curve fitting method, a comparable proportion of MFS and OS at 8 yr among groups was observed regardless of pathologic cancer features (p=0.9 and p=0.7, respectively). Limitations consisted of the retrospective nature of the study and the relatively small size of the patient population. At long-term follow-up, no significant differences between aRT and esRT were observed for MFS and OS. Our study, although based on retrospective data, suggests that esRT does not compromise cancer control and potentially reduces overtreatment associated with aRT. At long-term follow-up, no significant differences in terms of distant metastasis and mortality were observed between immediate postoperative adjuvant radiation therapy (aRT) and initial observation followed by early salvage radiation therapy (esRT) in case of prostate-specific antigen relapse. Our study suggests that esRT does not compromise cancer control and potentially reduces overtreatment associated with aRT. Copyright © 2016 European Association of Urology. Published by Elsevier B.V.

Experience with the use of real-time continuous glucose monitoring systems (RT-CGMS) in teenagers with type 1 diabetes mellitus (T1DM) is limited. We aimed to assess the possibility of glycaemic control improvement and to characterize the group of adolescents, who may gain long-term benefits from the use of the RT-CGMS. Forty T1DM patients, aged 14.6 ± 2.1 years, with diabetes duration 7.4 ± 3.6 years and initial HbA₁c 9.3 ± 1.5% were recruited. The analysis was based on one-month glucose sensors use, combined with the thorough family support. Patients were analysed in groups according to baseline HbA₁c: below and above 7.5%, and 10.0%. Comparison between patients with or without improvement in HbA₁c after 3-month follow-up was also performed. Patients' satisfaction based on the questionnaire was assessed. HbA₁c level in entire study group decreased after three months, from 9.3 ± 1.0% to 8.8 ± 1.6% (P<0.001). In the group with HbA1c improvement, reduction was the highest: 9.0 ± 1.3% vs. 8.0 ± 1.2% (P<0.001). Only the group with initial HbA₁c>10% did not achieve significant improvement: 11.2 ± 0.5% vs. 10.9 ± 1.1 (P=0.06). In satisfaction questionnaire the lowest scores (negative opinion) were reported by group of patients with initial HbA₁c above 10%, while the highest scores (positive opinion) were found in the group with improvement of HbA₁c after 3 month follow-up. Short-term use of CGMS RT, united with satisfaction questionnaire, performed in poorly controlled teenagers with T1DM, can be useful in defining the group of young patients, who can benefit from long-term CGMS RT use in metabolic control improvement.

Purpose: Concerns have been raised about the potential for worse treatment outcomes because of dosimetric inaccuracies related to tumor motion and increased toxicity caused by the spread of low-dose radiation to normal tissues in patients with locally advanced non-small cell lung cancer (NSCLC) treated with intensity modulated radiation therapy (IMRT). We therefore performed a population-based comparative effectiveness analysis of IMRT, conventional 3-dimensional conformal radiation therapy (3D-CRT), and 2-dimensional radiation therapy (2D-RT) in stage III NSCLC. Methods and Materials: We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify a cohort of patients diagnosed with stage III NSCLC frommore » 2002 to 2009 treated with IMRT, 3D-CRT, or 2D-RT. Using Cox regression and propensity score matching, we compared survival and toxicities of these treatments. Results: The proportion of patients treated with IMRT increased from 2% in 2002 to 25% in 2009, and the use of 2D-RT decreased from 32% to 3%. In univariate analysis, IMRT was associated with improved overall survival (OS) (hazard ratio [HR] 0.90, P=.02) and cancer-specific survival (CSS) (HR 0.89, P=.02). After controlling for confounders, IMRT was associated with similar OS (HR 0.94, P=.23) and CSS (HR 0.94, P=.28) compared with 3D-CRT. Both techniques had superior OS compared with 2D-RT. IMRT was associated with similar toxicity risks on multivariate analysis compared with 3D-CRT. Propensity score matched model results were similar to those from adjusted models. Conclusions: In this population-based analysis, IMRT for stage III NSCLC was associated with similar OS and CSS and maintained similar toxicity risks compared with 3D-CRT.« less

As glioblastoma progresses, patients experience a decline in health-related quality of life (HRQoL). Delaying this decline is an important treatment goal. In newly diagnosed glioblastoma, progression-free survival was prolonged when bevacizumab was added to radiotherapy plus temozolomide (RT/TMZ) versus placebo plus RT/TMZ (phase III AVAglio study; hazard ratio, 0.64; 95% CI, 0.55 to 0.74; P < .001). To ensure that addition of bevacizumab to standard-of-care therapy was not associated with HRQoL detriment, HRQoL assessment was a secondary objective. Patients completed European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires C30 and BN20 at each tumor assessment (Appendix Table A1, online only). Raw scores were converted to a 100-point scale and mean changes from baseline scores were evaluated (stable: < 10-point change; clinically relevant deterioration/improvement: ≥ 10-point change). Deterioration-free survival was the time to deterioration/progression/death; time to deterioration was the time to deterioration/death. Most evaluable patients who had not progressed (> 74%) completed all HRQoL assessments for at least 1 year of treatment, and almost all completed at least one HRQoL assessment at baseline (98.3% and 97.6%, bevacizumab and placebo arms, respectively). Mean changes from baseline did not reach a clinically relevant difference between arms for most items. HRQoL declined at progression in both arms. The addition of bevacizumab to RT/TMZ resulted in statistically longer (P < .001) deterioration-free survival across all items. Time to deterioration was not statistically longer in the placebo plus RT/TMZ arm (v bevacizumab) for any HRQoL item. The addition of bevacizumab to standard-of-care treatment for newly diagnosed glioblastoma had no impact on HRQoL during the progression-free period. © 2015 by American Society of Clinical Oncology.

Patients undergoing renal transplant (RT) have altered drug/opioid pharmacokinetics. Transversus abdominis plane (TAP) block in renal transplant recipients has been recently evaluated for analgesic and opioid-sparing potential by many trials. The studies comparing TAP-block to conventional analgesic regimens for RT were searched. Comparisons were made for total opioids consumed (as morphine-equivalents) during the first postoperative 24-h (primary objective), intraoperative, and immediate-postoperative period. Pain scores and postoperative nausea-vomiting (PONV) were also evaluated. Trial sequential analysis (TSA) was used to quantify the strength of analysis. Ten-trials with 258 and 237 patients in control and TAP-block group, respectively, were included. TAP-block decreased the 24-h (reported in 9-trials) opioid consumption by 14.61 ± 4.34 mg (reduction by 42.7%, random-effects, P < 0.001, I 2 = 97.82%). Sample size of the present analysis (472) was well past the required "information-size" variable (396) as per the TSA for a power of 85%. Intraoperative opioid consumption also decreased by 2.06 ± 0.63 mg (reduction of 27.8%) (random effects, P < 0.001, I 2 = 98.84%). Pain scores with TAP-block were significantly lower in both early and delayed postoperative phase. Odds ratio for PONV without TAP block was 1.99 ± 1.05 (Fixed-effects, P = 0.04, I 2 = 0%). Publication bias was likely (Egger's test, X-intercept=7.89, P < 0.05). TAP-block significantly lowers the intraoperative and cumulative postoperative 24-h opioid consumption in RT recipients. Persistent and better pain control is achieved when TAP-Block is used. Benefits of TAP block extend beyond the analgesic actions alone as it also decreases the 24-h incidence of postoperative nausea vomiting as well. The technique of the block needs standardization for RT recipients.

In spring 2009, a novel strain of influenza A originating in Veracruz, Mexico, quickly spread to the United States and throughout the world. This influenza A virus was the product of gene reassortment of 4 different genetic elements: human influenza, swine influenza, avian influenza, and Eurasian swine influenza. In the United States, New York was the epicenter of the swine influenza (H1N1) pandemic. Hospital emergency departments (EDs) were inundated with patients with influenza-like illnesses (ILIs) requesting screening for H1N1. Our ED screening, as well as many others, used a rapid screening test for influenza A (QuickVue A/B) because H1N1 was a variant of influenza A. The definitive laboratory test i.e., RT-PCR for H1N1 was developed by the Centers for Disease Control (Atlanta, GA) and subsequently distributed to health departments. Because of the extraordinary volume of test requests, health authorities restricted reverse transcription polymerase chain reaction (RT-PCR) testing. Hence most EDs, including our own, were dependent on rapid influenza diagnostic tests (RIDTs) for swine influenza. A positive rapid influenza A test was usually predictive of RT-PCR H1N1 positivity, but the rapid influenza A screening test (QuickVue A/B) was associated with 30% false negatives. The inability to rely on RIDTs for H1N1 diagnosis resulted in underdiagnosing H1N1. Confronted with adults admitted with ILIs, negative RIDTs, and restricted RT-PCR testing, there was a critical need to develop clinical criteria to diagnose probable swine influenza H1N1 pneumonia. During the pandemic, the Infectious Disease Division at Winthrop-University Hospital developed clinical criteria for adult admitted patients with ILIs and negative RIDTs. Similar to the one developed for the clinical diagnosis of legionnaire's disease. The Winthrop-University Hospital Infectious Disease Division's diagnostic weighted point score system for swine influenza H1N1 pneumonia is based on key clinical and laboratory features. During the "herald" wave of the swine influenza H1N1 pandemic, the diagnostic weighted point score system accurately identified probable swine influenza H1N1 pneumonia and accurately differentiated swine influenza H1N1 pneumonia from ILIs and other viral and bacterial community-acquired pneumonias. In hospitalized adults with ILIs and negative RIDTs, the diagnostic weighted diagnostic point score system, may be used to make a presumptive clinical diagnosis of swine influenza H1N1 pneumonia.

Mammaglobin, a member of secretoglobin family has been recognized as a breast cancer associated protein. Though the exact function of the protein is not fully known, its expression has been reported to be upregulated in human breast cancer.We focused on studying the expression of mammaglobin-B gene and protein in canine mammary tumor (CMT) tissue. Expression of mammaglobin-B mRNA and protein were assessed by quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC), respectively. High levels of mammaglobin-B mRNA expression (6.663 ± 0.841times) was observed in CMT as compared to age and breed matched healthy controls. Further, expression of mammaglobin-B protein was detected in paraffin-embedded mammary tumor tissues from the same subjects by IHC. Mammaglobin-B protein was overexpressed only in 6.67% of healthy mammary glands while, a high level of its expression was scored in 76.7% of the CMT subjects. Moreover, no significant differences in terms of IHC score and qRT-PCR score with respect to CMT histotypes or tumor grades were observed, indicating that mammaglobin-B over-expression occurred irrespective of CMT types or grades. Overall, significantly increased expression of mammaglobin-B protein was found in CMTs with respect to healthy mammary glands, which positively correlates to its transcript. These findings suggest that overexpression of mammaglobin-B is associated with tumors of canine mammary glands.

In this study, the factors that effect the morbidity and mortality in patients with penetrating colonic injuries were evaluated. Fourty-two patients (37 males, 5 females; mean age 30,1; range 14 to 63 years) with penetrating colonic trauma were evaluated according to age, gender, type of penetrating trauma, location and severity of the colonic injury, associated injury, interval between the trauma and the definitive operation, hemodynamic status, blood transfusion requirement, fecal contamination, surgical procedure, postoperative complication and mortality. Type of the penetrating trauma was stab injury in twenty-eight (67%) patients, and gunshot injury in fourteen (33%) patients. The mean Colon Injury Severity Score was 2,1. The mean Abdominal Trauma Index (ATI) was 17,2 and it was over than 25 in eight (19%) patients. The symptoms of shock were present in eleven (26%) patients at admission. Blood transfusions were applied in sixteen (38%) patients. In twenty-one patients intraabdominal bleeding was observed and it was more than 500 mL in eleven (26%) patients. Primary repair was performed in 36 (86%) of the 42 patients and colostomy was performed in six (14%) patients. Morbidity and mortality rates were 41% and 10% respectively. It was found that morbidity rates were increased in patients with ATI score higher than 25, and mortality rates were increased in patients presenting shock at admission, with the amount of intraabdominal blood more than 500 mL, and who needed three or more units of blood transfusion. The primary repair of the penetrating colon trauma can be performed confidently in the hemodynamically stable patients with ATI score less than 25.

To investigate the use of machine learning to empirically determine the risk of individual surgical procedures and to improve surgical models with this information. American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data from 2005 to 2009 were used to train support vector machine (SVM) classifiers to learn the relationship between textual constructs in current procedural terminology (CPT) descriptions and mortality, morbidity, Clavien 4 complications, and surgical-site infections (SSI) within 30 days of surgery. The procedural risk scores produced by the SVM classifiers were validated on data from 2010 in univariate and multivariate analyses. The procedural risk scores produced by the SVM classifiers achieved moderate-to-high levels of discrimination in univariate analyses (area under receiver operating characteristic curve: 0.871 for mortality, 0.789 for morbidity, 0.791 for SSI, 0.845 for Clavien 4 complications). Addition of these scores also substantially improved multivariate models comprising patient factors and previously proposed correlates of procedural risk (net reclassification improvement and integrated discrimination improvement: 0.54 and 0.001 for mortality, 0.46 and 0.011 for morbidity, 0.68 and 0.022 for SSI, 0.44 and 0.001 for Clavien 4 complications; P < .05 for all comparisons). Similar improvements were noted in discrimination and calibration for other statistical measures, and in subcohorts comprising patients with general or vascular surgery. Machine learning provides clinically useful estimates of surgical risk for individual procedures. This information can be measured in an entirely data-driven manner and substantially improves multifactorial models to predict postoperative complications. Copyright © 2014 Elsevier Inc.

Vitamin D deficiency is a common issue, particularly in obese populations, and is tested by assessing serum 25(OH)D concentrations. This study aimed to identify factors that contribute to the vitamin D status in fifty morbidly obese individuals recruited prior to bariatric surgery. Data collected included serum 25(OH)D concentrations, dietary and supplement intake of vitamin D, sun exposure measures, skin colour via spectrophotometry, and genotype analysis of several single nucleotide polymorphisms in the vitamin D metabolism pathway. Results showed a significant correlation between serum 25(OH)D concentrations and age, and serum 25(OH)D and ITAC score (natural skin colour). Natural skin colour accounted for 13.5% of variation in serum 25(OH)D, with every 10° increase in ITAC score (i.e., lighter skin) leading to a 9 nmol/L decrease in serum 25(OH)D. Multiple linear regression using age, ITAC score, and average UV index in the three months prior to testing, significantly predicted serum 25(OH)D concentrations ( R ² = 29.7%). Single nucleotide polymorphisms for all vitamin D genes tested, showed lower serum 25(OH)D for those with the rare genotype compared to the common genotype; this was most pronounced for fok1 and rs4588 , where those with the rare genotype were insufficient (<50 nmol/L), and those with the common genotype were sufficient (≥50 nmol/L). Assessing vitamin D status in individuals with morbid obesity requires testing of 25(OH)D, but potential risk factors for this population include natural skin colour and age.

For more accurate estimation of the global burden of pregnancy associated disease, clarity is needed on definition and assessment of non-severe maternal morbidity. Our study aimed to define maternal morbidity with clear criteria for identification at primary care level and estimate the distribution of and evaluate associations between physical (infective and non-infective) and psychological morbidities in two different low-income countries. Cross sectional study with assessment of morbidity in early pregnancy (34%), late pregnancy (35%) and the postnatal period (31%) among 3459 women from two rural communities in Pakistan (1727) and Malawi (1732). Trained health care providers at primary care level used semi-structured questionnaires documenting signs and symptoms, clinical examination and laboratory tests which were bundled to reflect infectious, non-infectious and psychological morbidity. One in 10 women in Malawi and 1 in 5 in Pakistan reported a previous pregnancy complication with 1 in 10 overall reporting a previous neonatal death or stillbirth. In the index pregnancy, 50.1% of women in Malawi and 53% in Pakistan were assessed to have at least one morbidity (infective or non-infective). Both infective (Pakistan) and non-infective morbidity (Pakistan and Malawi) was lower in the postnatal period than during pregnancy. Multiple morbidities were uncommon (<10%). There were marked differences in psychological morbidity: 26.9% of women in Pakistan 2.6% in Malawi had an Edinburgh Postnatal Depression Score (EPDS) > 9. Complications during a previous pregnancy, infective morbidity (p <0.001), intra or postpartum haemorrhage (p <0.02) were associated with psychological morbidity in both settings. Our findings highlight the need to strengthen the availability and quality of antenatal and postnatal care packages. We propose to adapt and improve the framework and criteria used in this study, ensuring a basic set of diagnostic tests is available, to ensure more robust assessment of non-severe maternal morbidity.

Morbidity associated with autologous bone graft harvest is an important factor in determining the utility of expensive alternatives such as recombinant bone morphogenic protein. The most frequently reported complication associated with graft harvest is chronic pain. To prospectively determine the degree of pain and morbidity associated with autologous iliac crest bone graft harvest and its effect on activities of daily living. Prospective observational cohort study. One hundred ten adult patients undergoing elective posterior lumbar spinal fusion surgery involving autologous iliac crest bone graft harvest. Patient self-reported Visual Analog Scale (VAS) scores for pain and a study-specific questionnaire regarding activities of daily living. One hundred ten patients were prospectively enrolled. Postoperative VAS scores (0-100) for harvest site pain were obtained at 6-week, 6- and 12-month follow-up. Patients completed a 12-month questionnaire regarding the persistence of specific symptoms and resulting limitation of specific activities. One hundred four patients were available for 1-year follow-up. Mean VAS pain scores (scale 0-100) at 6 weeks, 6 and 12 months were 22.7 (standard deviation [SD], 25.9), 15.9 (SD, 21.5), and 16.1 (SD, 24.6), respectively. At 12 months, 16.5% reported more severe pain from the harvest site than the primary surgical site, 29.1% reported numbness, and 11.3% found the degree of numbness bothersome, whereas 3.9% were bothered by scar appearance. With respect to activity limitations resulting from harvest site pain at 1 year, 15.1% reported some difficulty walking, 5.2% with employment, 12.9% with recreation, 14.1% with household chores, 7.6% with sexual activity, and 5.9% irritation from clothing. There is a significant rate of persistent pain and morbidity from iliac crest bone graft harvest when associated with elective spine surgery. Mean pain scores progressively decline over the first postoperative year. Nevertheless, harvest site pain remains functionally limiting in a significant percentage of patients 1 year after surgery. Rates of functional limitation are higher than previously reported and may be because of increased sensitivity of the prospective study design and targeted investigation of these specific symptoms. Validity of these findings is necessarily limited by patient ability to discriminate harvest site pain from alternative sources of back and buttock pain.

To compare the outcomes of umbilical hernia repair in patients with and without signs of portal hypertension, such as esophageal varices or ascites; to assess the effect of emergency surgery on complication rates; and to identify predictors of postoperative mortality. Database search from January 1, 2005, through December 31, 2009. North American hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program initiative. We studied patients who underwent umbilical hernia repair. Those with congestive heart failure, disseminated malignant tumor, or chronic renal failure while undergoing dialysis were excluded. Preoperative variables and perioperative course were analyzed. Main outcome measures were morbidity and mortality after umbilical hernia repair. A total of 390 patients with ascites and/or esophageal varices formed the study group, and the remaining 22 952 patients formed the control group. The overall morbidity and mortality rates for the study group were 13.1% and 5.1%, whereas these rates were 3.9% and 0.1% for the control group, respectively (P < .001). For the study group, the mortality after elective repair among patients with a model for end-stage liver disease (MELD) score greater than 15 was 11.1% compared with 1.3% in patients with a MELD score of 15 or less. The patients with ascites and/or esophageal varices underwent emergency surgery more frequently than the control group (37.7% vs 4.9%; P < .001). Emergency surgery for the study group was associated with a higher morbidity than elective surgery (20.8% vs 8.3%; P < .001) but not a significantly higher mortality (7.4% vs 3.7%; P = .11). However, logistic regression analysis showed that age older than 65 years, MELD score higher than 15, albumin level less than 3.0 g/dL (to convert to grams per liter, multiply by 10), and sepsis at presentation were more predictive of postoperative mortality. Umbilical hernia repair in the presence of ascites and/or esophageal varices is associated with significant postoperative complication rates. Emergency surgery is associated with higher morbidity rates but not significantly higher mortality rates. Elective repair of umbilical hernia should be avoided for those with adverse predictors, such as age older than 65 years, MELD score higher than 15, and albumin level less than 3.0 g/dL.

Casimiro de Deus Cardoso, Cejana; Giordani, Adelmo Jose; Borri Wolosker, Angela Maria

Purpose: To evaluate the clinical and radiologic response of patients with Graves' ophthalmopathy given low-dose orbital radiotherapy (RT) with a protracted fractionation. Methods and Materials: Eighteen patients (36 orbits) received orbital RT with a total dose of 10 Gy, fractionated in 1 Gy once a week over 10 weeks. Of these, 9 patients received steroid therapy as well. Patients were evaluated clinically and radiologically at 6 months after treatment. Clinical response assessment was carried out using three criteria: by physical examination, by a modified clinical activity score, and by a verbal questionnaire considering the 10 most common signs and symptomsmore » of the disease. Radiologic response was assessed by magnetic resonance imaging. Results: Improvement in ocular pain, palpebral edema, visual acuity, and ocular motility was observed in all patients. Significant decrease in symptoms such as tearing (p < 0.001) diplopia (p = 0.008), conjunctival hyperemia (p = 0.002), and ocular grittiness (p = 0.031) also occurred. Magnetic resonance imaging showed decrease in ocular muscle thickness and in the intensity of the T2 sequence signal in the majority of patients. Treatments were well tolerated, and to date no complications from treatment have been observed. There was no statistical difference in clinical and radiologic response between patients receiving RT alone and those receiving RT plus steroid therapy. Conclusion: RT delivered in at a low dose and in a protracted scheme should be considered as a useful therapeutic option for patients with Graves' ophthalmopathy.« less

A recent randomized trial (NCT01535209) demonstrated no difference in neurocognitive function between stereotactic radiotherapy of the tumor bed (SRT-TB) and whole brain radiotherapy (WBRT) in patients with resected single brain metastasis. Patients treated with SRT-TB had lower overall survival compared with the WBRT arm. Here, we compared the health-related quality of life (HRQOL) in patients who received WBRT vs. SRT-TB. A self-reported questionnaire was used to assess HRQOL (EORTC QLQ-C30 with the QLQ-BN20 module) before RT, 2 months after RT, and every 3 months thereafter. HRQOL results are presented as mean scores and compared between groups. Of 59 randomized patients, 37 (64%) were eligible for HRQOL analysis, 15 received SRT-TB, and 22 had WBRT. There were no differences between groups in global health status and main function scales/symptoms (except for drowsiness and appetite loss, which were worse with WBRT 2 months after RT). Global health status decreased 2 and 5 months after RT, but significantly only for SRT-TB (p = 0.025). Physical function decreased significantly 5 months after SRT-TB (p = 0.008). Future uncertainty worsened after RT, but significantly only for SRT-TB after 2 months (p = 0.036). Patients treated with WBRT had significant worsening of appetite, hair loss, and drowsiness after treatment. Despite higher symptom burden after WBRT attributed to the side effects of RT (such as appetite loss, drowsiness, and hair loss), global health status, physical functioning, and future uncertainty favored WBRT compared with SRT-TB. This may be related to the compromised brain tumor control with omission of WBRT.

Purpose: To prospectively compare the effect of prophylactic and therapeutic whole brain radiotherapy (WBRT) on memory function in patients with and without brain metastases. Methods and Materials: Adult patients with and without brain metastases (n = 44) were prospectively evaluated with serial cognitive testing, before RT (T0), after starting RT (T1), at the end of RT (T2), and 6-8 weeks (T3) after RT completion. Data were obtained from small-cell lung cancer patients treated with prophylactic cranial irradiation, patients with brain metastases treated with therapeutic cranial irradiation (TCI), and breast cancer patients treated with RT to the breast. Results: Before therapy,more » prophylactic cranial irradiation patients performed worse than TCI patients or than controls on most test scores. During and after WBRT, verbal memory function was influenced by pretreatment cognitive status (p < 0.001) and to a lesser extent by WBRT. Acute (T1) radiation effects on verbal memory function were only observed in TCI patients (p = 0.031). Subacute (T3) radiation effects on verbal memory function were observed in both TCI and prophylactic cranial irradiation patients (p = 0.006). These effects were more pronounced in patients with above-average performance at baseline. Visual memory and attention were not influenced by WBRT. Conclusions: The results of our study have shown that WBRT causes cognitive dysfunction immediately after the beginning of RT in patients with brain metastases only. At 6-8 weeks after the end of WBRT, cognitive dysfunction was seen in patients with and without brain metastases. Because cognitive dysfunction after WBRT is restricted to verbal memory, patients should not avoid WBRT because of a fear of neurocognitive side effects.« less

Although chemotherapy is used routinely in pediatric medulloblastoma (MB) patients, its benefit for adult MB is unclear. We evaluated the survival impact of adjuvant chemotherapy in adult MB. Using the National Cancer Data Base, we identified patients aged 18 years and older who were diagnosed with MB in 2004-2012 and underwent surgical resection and adjuvant craniospinal irradiation (CSI). Patients were divided into those who received adjuvant CSI and chemotherapy (CRT) or CSI alone (RT). Predictors of CRT compared with RT were evaluated with univariable and multivariable logistic regression. Survival analysis was limited to patients receiving CSI doses between 23 and 36 Gy. Overall survival (OS) was evaluated using the Kaplan-Meier estimator, log-rank test, multivariable Cox proportional hazards modeling, and propensity score matching. Of the 751 patients included, 520 (69.2%) received CRT, and 231 (30.8%) received RT. With median follow-up of 5.0 years, estimated 5-year OS was superior in patients receiving CRT versus RT (86.1% vs 71.6%, P < .0001). On multivariable analysis, after controlling for risk factors, CRT was associated with superior OS compared with RT (HR: 0.53; 95%CI: 0.32-0.88, P = .01). On planned subgroup analyses, the 5 year OS of patients receiving CRT versus RT was improved for M0 patients (P < .0001), for patients receiving 36 Gy CSI (P = .0007), and for M0 patients receiving 36 Gy CSI (P = .0008). This national database analysis demonstrates that combined postoperative chemotherapy and radiotherapy are associated with superior survival for adult MB compared with radiotherapy alone, even for M0 patients who receive high-dose CSI. © The Author(s) 2016.

Purpose: To correlate computed tomography (CT) imaging features of spinal metastases with pain relief after radiotherapy (RT). Methods and Materials: Thirty-three patients receiving computed tomography (CT)-simulated RT for spinal metastases in an outpatient palliative RT clinic from January 2007 to October 2008 were retrospectively reviewed. Forty spinal metastases were evaluated. Pain response was rated using the International Bone Metastases Consensus Working Party endpoints. Three musculoskeletal radiologists and two orthopaedic surgeons evaluated CT features, including osseous and soft tissue tumor extent, presence of a pathologic fracture, severity of vertebral height loss, and presence of kyphosis. Results: The mean patient age wasmore » 69 years; 24 were men and 9 were women. The mean worst pain score was 7/10, and the mean total daily oral morphine equivalent was 77.3 mg. Treatment doses included 8 Gy in one fraction (22/33), 20 Gy in five fractions (10/33), and 20 Gy in eight fractions (1/33). The CT imaging appearance of spinal metastases included vertebral body involvement (40/40), pedicle involvement (23/40), and lamina involvement (18/40). Soft tissue component (10/40) and nerve root compression (9/40) were less common. Pathologic fractures existed in 11/40 lesions, with resultant vertebral body height loss in 10/40 and kyphosis in 2/40 lesions. At months 1, 2, and 3 after RT, 18%, 69%, and 70% of patients experienced pain relief. Pain response was observed with various CT imaging features. Conclusions: Pain response after RT did not differ in patients with and without pathologic fracture, kyphosis, or any other CT features related to extent of tumor involvement. All patients with painful spinal metastases may benefit from palliative RT.« less

Purpose: The optimal treatment of clinically localized prostate cancer is controversial. Most studies focus on biochemical (PSA) failure when comparing radical prostatectomy (RP) with radiation therapy (RT), but this endpoint has not been validated as predictive of overall survival (OS) or cause-specific survival (CSS). We analyzed the available literature to determine whether reliable conclusions could be made concerning the effectiveness of RP compared with RT with or without androgen deprivation therapy (ADT), assuming current treatment standards. Methods: Articles published between February 29, 2004, and March 1, 2015, that compared OS and CSS after RP or RT with or without ADTmore » were included. Because the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) system emphasis is on randomized controlled clinical trials, a reliability score (RS) was explored to further understand the issues associated with the study quality of observational studies, including appropriateness of treatment, source of data, clinical characteristics, and comorbidity. Lower RS values indicated lower reliability. Results: Fourteen studies were identified, and 13 were completely evaluable. Thirteen of the 14 studies (93%) were observational studies with low-quality evidence. The median RS was 12 (range, 5-18); the median difference in 10-year OS and CSS favored RP over RT: 10% and 4%, respectively. In studies with a RS ≤12 (average RS 9) the 10-year OS and CSS median differences were 17% and 6%, respectively. For studies with a RS >12 (average RS 15.5), the 10-year OS and CSS median differences were 5.5% and 1%, respectively. Thus, we observed an association between low RS and a higher percentage difference in OS and CSS. Conclusions: Reliable evidence that RP provides a superior CSS to RT with ADT is lacking. The most reliable studies suggest that the differences in 10-year CSS between RP and RT are small, possibly <1%.« less

To evaluate the response, survival and safety on 3-D conformal radiotherapy (3D-CRT) for major portal vein tumor thrombosis (PVTT) combined with hepatic arterial infusion chemotherapy (HAIC) for advanced hepatocellular carcinoma (HCC). In this retrospective study, 83 advanced HCC patients treated with HAIC who met the following criteria were enrolled: (i) PVTT of the main trunk or first branch of the portal vein; (ii) no extrahepatic metastasis; (iii) Child-Pugh score of 5-7; (iv) performance status of 0 or 1; and (v) no history of sorafenib treatment. The response, overall survival (OS), time to treatment failure (TTF), post-progression survival (PPS) and safety were compared between HAIC combined with 3D-CRT for PVTT (RT group, n = 41) and HAIC alone (non-RT group, n = 42). The objective response of PVTT was significantly higher in the RT group (56.1%) than in the non-RT group (33.3%), while that of intrahepatic tumor and OS were not significantly different between groups. Median OS, TTF and PPS were significantly longer in the RT group than in the non-RT group (8.6 and 5.0 months, 5.0 and 2.7 months, and 5.3 and 1.5 months, respectively) among intrahepatic tumor non-responders to HAIC, whereas those were not significantly different between groups among intrahepatic tumor responders to HAIC. By multivariate analysis, the combination of 3D-CRT with HAIC was an independent contributing factor for OS (hazard ratio, 3.2; 95% confidence interval, 1.692-6.021; P < 0.001) among intrahepatic HCC non-responders to HAIC. 3D-CRT for PVTT combined with HAIC could provide survival benefit to non-responder to HAIC. © 2014 The Japan Society of Hepatology.

Definitive chemoradiotherapy (CRT) is the standard treatment for locally advanced head and neck cancer (HNC). However, for very elderly patients, the comparison of benefit/risk between definitive radiotherapy (RT) with and without systemic chemotherapy was equivocal. The study was a single-institute, retrospective, cohort study. Seventy patients aged ≥75 years who had a locally advanced HNC were enrolled. The patients were divided into those with CRT and those with RT alone. Survival, compliance/adverse events and independent prognostic factors were analyzed. For baseline characteristics, the patients who received RT alone had worse performance status, comorbidity score and neutrophil-to-lymphocyte ratio. However, during definitive therapy, the CRT group had more adverse events such as neutropenia, febrile neutropenia and thrombocytopenia. There were no significant differences in disease-specific survival (DSS) and overall survival (OS) (P = 0.864 and 0.788, respectively). As to OS, several independent prognostic factors were identified. Performance status (hazard ratio [HR], 2.312; confidence interval [CI], 1.176-4.546; P = 0.015), clinical T staging (HR, 2.240; 95% CI, 1.021-4.913; P = 0.004) and total RT dose (HR, 2.555; 95% CI, 1.246-5.238; P = 0.010) were independent prognostic factors of OS. Definitive RT with or without systemic chemotherapy did not significantly influence DSS and OS for very elderly patients. Therefore, for elderly patients aged ≥ 75 years who have HNC, conservative RT might be sufficient for treatment purposes. © 2017 John Wiley & Sons Australia, Ltd.

Risk-adjusted scoring systems in colorectal surgery.

Consequent to recent advances in surgical techniques and management, survival rate has increased substantially over the last 25 years, particularly in colorectal cancer patients. However, post-operative morbidity and mortality from colorectal cancer vary widely across the country. Therefore, standardised outcome measures are emphasised not only for professional accountability, but also for comparison between treatment units and regions. In a heterogeneous population, the use of crude mortality as an outcome measure for patients undergoing surgery is simply misleading. Meaningful comparisons, however, require accurate risk stratification of patients being analysed before conclusions can be reached regarding the outcomes recorded. Sub-specialised colorectal surgical units usually dedicated to more complex and high-risk operations. The need for accurate risk prediction is necessary in these units as both mortality and morbidity often are tools to justify the practice of high-risk surgery. The Acute Physiology And Chronic Health Evaluation (APACHE) is a system for classifying patients in the intensive care unit. However, APACHE score was considered too complex for general surgical use. The American Society of Anaesthesiologists (ASA) grade has been considered useful as an adjunct to informed consent and for monitoring surgical performance through time. ASA grade is simple but too subjective. The Physiological & Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) and its variant Portsmouth POSSUM (P-POSSUM) were devised to predict outcomes in surgical patients in general, taking into account of the variables in the case-mix. POSSUM has two parts, which include assessment of physiological parameters and operative scores. There are 12 physiological parameters and 6 operative measures. The physiological parameters are taken at the time of surgery. Each physiological parameter or operative variable is sub-divided into three or four levels with an exponentially increasing score. However, POSSUM and P-POSSUM over-predict mortality in patients who have had colorectal surgery. Discrepancies in these models have led to the introduction of a specialty-specific POSSUM: the ColoRectal POSSUM (CR-POSSUM). CR-POSSUM only uses six physiological parameters and four operative measures for prediction of mortality. It is much simplified to allow ease of use. Copyright © 2010 Surgical Associates Ltd.

Rib fractures are common among patients sustaining blunt trauma, and are markers of severe bodily and solid organ injury. They are associated with high morbidity and mortality, including multiple pulmonary complications, and can lead to chronic pain and disability. Clinical and radiographic scoring systems have been developed at several institutions to predict risk of complications. Clinical strategies to reduce morbidity have been studied, including multimodal pain management, catheter-based analgesia, pulmonary hygiene, and operative stabilization. In this article, we review risk factors for morbidity and complications, intervention strategies, and discuss experience with bundled clinical pathways for rib fractures. In addition, we introduce the multidisciplinary rib fracture management protocol used at our level I trauma center.
