To identify the most accurate quantitative electroencephalographic (qEEG) predictor(s) of unfavorable post-ischemic stroke outcome, and its discriminative capacity compared to already known demographic, clinical and imaging prognostic markers. Prospective cohort of 151 consecutive anterior circulation ischemic stroke patients followed for 12 months. EEG was recorded within 72 h and at discharge or 7 days post-stroke. QEEG (global band power, symmetry, affected/unaffected hemisphere and time changes) indices were calculated from mean Fast Fourier Transform and analyzed as predictors of unfavorable outcome (mRS ≥ 3), at discharge and 12 months poststroke, before and after adjustment for age, admission NIHSS and ASPECTS. Higher delta, lower alpha and beta relative powers (RP) predicted outcome. Indices with higher discriminative capacity were delta-theta to alpha-beta ratio (DTABR) and alpha RP. Outcome models including either of these and other clinical/imaging stroke outcome predictors were superior to models without qEEG data. In models with qEEG indices, infarct size was not a significant outcome predictor. DTAABR and alpha RP are the best qEEG indices and superior to ASPECTS in post-stroke outcome prediction. They improve the discriminative capacity of already known clinical and imaging stroke outcome predictors, both at discharge and 12 months after stroke. qEEG indices are independent predictors of stroke outcome.

Tuberculosis (TB) represents a major global health problem. The prognosis of clinically active tuberculosis depends on the complex interactions between Mycobacterium tuberculosis (Mtb) and its host. In recent years, autophagy receives particular attention for its role in host defense against intracellular pathogens, including Mtb. In present study, we aim to investigate the relationship of autophagy induction by clinical isolates of Mtb with the clinical outcomes in patients with TB. We collected 185 clinical isolates of Mtb, and determined the effect of these Mtb isolates on autophagy induction in macrophages. It was found that most of clinical isolates of Mtb were able to induce autophagosome formation in macrophages, however, the autophagy-inducing ability varied significantly among different isolates. Of importance, our results revealed that patients infected by Mtb with poor autophagy-inducing ability displayed more severe radiographic extent of disease (p<0.001), and were more likely to have unfavorable treatment outcomes (p<0.001). No significant association was observed between the extent of Mtb-induced autophagy with some socio-demographic characteristics (such as gender, age and tobacco consumption), and some laboratory tests (such as hemoglobin, leukocyte count and erythrocyte sedimentation rate). Furthermore, results from logistic regression analysis demonstrated that the defect in autophagy induction by clinical isolates of Mtb was an independent risk factor for far-advanced radiographic disease (aOR 4.710 [1.93-11.50]) and unfavorable treatment outcomes (aOR 8.309 [2.22-28.97]) in TB. These data indicated that the defect in autophagy induction by Mtb isolates increased the risk of poor clinical outcomes in TB patients, and detection of clinical isolates-induced autophagosome formation might help evaluate the TB outcomes.

Background We assessed the impact of home-based care (HBC) for HIV+ patients, comparing outcomes between two groups of Zambians receiving antiretroviral therapy (ART) who lived in villages with and without HBC teams. Methods We conducted a retrospective cohort study using medical charts from Macha Mission Hospital, a hospital providing HIV care in Zambia's rural Southern Province. Date of birth, date of ART initiation, place of residence, sex, body mass index (BMI), CD4+ cell count, and hemoglobin (Hgb) were abstracted. Logistic regression was used to test our hypothesis that HBC was associated with treatment outcomes. Results Of 655 patients, 523 (80%) were eligible and included in the study. There were 428 patients (82%) with favorable outcomes (alive and on ART) and 95 patients (18%) with unfavorable outcomes (died, lost to follow-up, or stopped treatment). A minority of the 523 eligible patients (n = 84, 16%) lived in villages with HBC available. Living in a village with HBC was not significantly associated with treatment outcomes; 80% of patients in a village with HBC had favorable outcomes, compared to 82% of patients in a village without HBC (P = 0.6 by χ2). In bivariable analysis, lower BMI (P<0.001), low CD4+ cell count (P = 0.02), low Hgb concentration (P = 0.02), and older age at ART initiation (P = 0.047) were associated with unfavorable outcomes. In multivariable analysis, low BMI remained associated with unfavorable outcomes (P<0.001). Conclusions We did not find that living in a village with HBC available was associated with improved treatment outcomes. We speculate that the ART clinic's rigorous treatment preparation before ART initiation and continuous adherence counseling during ART create a motivated group of patients whose outcomes did not improve with additional HBC support. An alternative explanation is that the quality of the HBC program is suboptimal. PMID:23236351

To study clinical features and outcome of community-acquired bacterial meningitis in alcoholic patients. Patients with a history of alcoholism were selected from our nationwide, prospective cohort on community-acquired bacterial meningitis performed from March 2006 to October 2014. Data on patient history, symptoms and signs on admission, treatment, and outcome were prospectively collected. Of 1359 included episodes, 88 episodes (6%) occurred in 88 alcoholic patients. Seizures as presenting symptom were present in 18% alcoholic patients, and 23% presented with co-existing pneumonia. Causative organisms were Streptococcus pneumoniae in 76%, Listeria monocytogenes in 8%, and Neisseria meningitidis in 6% of patients. A high rate of systemic complications occurred with respiratory failure in 40% and endocarditis in 9% of patients. Outcome was unfavorable in 58% of alcoholic patients, and 25% died. Alcoholism was associated with unfavorable outcome in a multivariate analysis (OR 1.96; 95% CI 1.12-3.46; P = 0.019), but not with death (OR 0.76; 95% CI 0.35-1.68; P = 0.762). Alcoholic bacterial meningitis patients often have an unfavorable outcome, which appears to result from a high rate of systemic complications, mainly respiratory failure. Seizures are common in alcoholic patients and warrant caution of development of an alcohol withdrawal syndrome. Copyright © 2017. Published by Elsevier Ltd.

Ground-level fall is the most common cause of traumatic intracranial hemorrhage (TICH) in the elderly, and is a major cause of morbidity and mortality in that population. A retrospective study was carried out to evaluate whether the use of warfarin/low-dose aspirin (LDA) is predictive of unfavorable outcomes in geriatric patients who sustain a fall-induced TICH. Charts of 76 geriatric patients (≥ 65 years-of-age) with fall-induced TICH were reviewed. The number of patients taking warfarin and LDA was 12 and 21, respectively, whereas the other 43 took neither medication (non-user group). The frequency of patients with unfavorable outcomes (Glasgow Outcome Scale score of 1-3) at discharge was calculated. Furthermore, variables predictive of unfavorable outcomes were identified by logistic regression analysis. The frequency of patients with unfavorable outcomes was 75% in the warfarin group, 33% in the LDA group and 27% in the non-user group, respectively. The risk of having unfavorable outcomes was significantly higher in the warfarin group compared with the LDA group (P = 0.03) and non-user group (P < 0.01). Logistic regression analysis showed that variables predictive of unfavorable outcomes were: age, initial Glasgow Coma Scale score ≤ 13 and presence of midline shift ≥ 5 mm. The use of warfarin, but not of LDA, might be associated with unfavorable outcomes in elderly with fall-induced TICH. The risk of TICH should be communicated properly to elderly taking warfarin. The information might be important not only to trauma surgeons who take care of injured elderly, but also to geriatric physicians who prescribe warfarin/LDA to them. © 2012 Japan Geriatrics Society.

There remains a proportion of patients with unfavorable outcomes after aneurysmal subarachnoid hemorrhage, of particular relevance in those who present with a good clinical grade. A forewarning of those at risk provides an opportunity towards more intensive monitoring, investigation, and prophylactic treatment prior to the clinical manifestation of advancing cerebral injury. To assess whether biochemical markers sampled in the first days after the initial hemorrhage can predict poor outcome. All patients recruited to the multicenter Simvastatin in Aneurysmal Hemorrhage Trial (STASH) were included. Baseline biochemical profiles were taken between time of ictus and day 4 post ictus. The t-test compared outcomes, and a backwards stepwise binary logistic regression was used to determine the factors providing independent prediction of an unfavorable outcome. Baseline biochemical data were obtained in approximately 91% of cases from 803 patients. On admission, 73% of patients were good grade (World Federation of Neurological Surgeons grades 1 or 2); however, 84% had a Fisher grade 3 or 4 on computed tomographic scan. For patients presenting with good grade on admission, higher levels of C-reactive protein, glucose, and white blood cells and lower levels of hematocrit, albumin, and hemoglobin were associated with poor outcome at discharge. C-reactive protein was found to be an independent predictor of outcome for patients presenting in good grade. Early recording of C-reactive protein may prove useful in detecting those good grade patients who are at greater risk of clinical deterioration and poor outcome.

Uncertainty regarding the long-term functional outcome of patients who awaken from coma after cardiac operations is difficult for families and physicians and may delay rehabilitation. We studied the long-term functional status of these patients to determine if duration of coma predicted outcome. We followed 71 patients who underwent cardiac operations; recovered their ability to respond to verbal commands after coma associated with postoperative stroke, encephalopathy, and/or seizures; and were discharged from the hospital. The Glasgow Outcome Scale Extended (GOSE) was used to assess functional disability 2 to 4 years after discharge. Outcomes were classified as favorable (GOSE scores 7 and 8) and unfavorable (GOSE scores 1-6). Of 71 patients identified, 39 were interviewed, 15 died, 1 refused to be interviewed, and 16 were lost to follow-up. Of the 54 patients with completed GOSE evaluations, only 15 (28%) had favorable outcomes. Among patients with unfavorable outcomes, 15 (28%) died, 14 (26%) survived with moderate disabilities, and 10 (18%) had severe disabilities. Factors associated with unfavorable outcomes were increases in duration of coma (p = 0.007), time in intensive care (p = 0.006), length of hospitalization (p = 0.004), and postoperative serum creatine kinase levels (p = 0.006). Only duration of coma was an independent predictor of unfavorable outcome (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.008-1.537; p = 0.042). Patients with durations of coma greater than 4 days were more likely to have unfavorable outcomes (OR, 5.1; 95% CI, 1.3-21.3; p = 0.02). Two thirds of comatose patients who survived to discharge after cardiac operations had unfavorable long-term functional outcomes. A longer duration of unconsciousness is a predictor of unfavorable outcome. Copyright © 2013 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

OBJECTIVE Symptomatic chronic subdural hematoma (CSDH) will become an increasingly common presentation in neurosurgical practice as the population ages, but quality evidence is still lacking to guide the optimal management for these patients. The British Neurosurgical Trainee Research Collaborative (BNTRC) was established by neurosurgical trainees in 2012 to improve research by combining the efforts of trainees in each of the United Kingdom (UK) and Ireland's neurosurgical units (NSUs). The authors present the first study by the BNTRC that describes current management and outcomes for patients with CSDH throughout the UK and Ireland. This provides a resource both for current clinical practice and future clinical research on CSDH. METHODS Data on management and outcomes for patients with CSDH referred to UK and Ireland NSUs were collected prospectively over an 8-month period and audited against criteria predefined from the literature: NSU mortality < 5%, NSU morbidity < 10%, symptomatic recurrence within 60 days requiring repeat surgery < 20%, and unfavorable functional status (modified Rankin Scale score of 4-6) at NSU discharge < 30%. RESULTS Data from 1205 patients in 26 NSUs were collected. Bur-hole craniostomy was the most common procedure (89%), and symptomatic recurrence requiring repeat surgery within 60 days was observed in 9% of patients. Criteria on mortality (2%), rate of recurrence (9%), and unfavorable functional outcome (22%) were met, but morbidity was greater than expected (14%). Multivariate analysis demonstrated that failure to insert a drain intraoperatively independently predicted recurrence and unfavorable functional outcome (p = 0.011 and p = 0.048, respectively). Increasing patient age (p < 0.00001), postoperative bed rest (p = 0.019), and use of a single bur hole (p = 0.020) independently predicted unfavorable functional outcomes, but prescription of high-flow oxygen or preoperative use of antiplatelet medications did not. CONCLUSIONS This is the largest prospective CSDH study and helps establish national standards. It has confirmed in a real-world setting the effectiveness of placing a subdural drain. This study identified a number of modifiable prognostic factors but questions the necessity of some common aspects of CSDH management, such as enforced postoperative bed rest. Future studies should seek to establish how practitioners can optimize perioperative care of patients with CSDH to reduce morbidity as well as minimize CSDH recurrence. The BNTRC is unique worldwide, conducting multicenter trainee-led research and audits. This study demonstrates that collaborative research networks are powerful tools to interrogate clinical research questions.

OBJECT Subarachnoid hemorrhage (SAH) is usually caused by a ruptured intracranial aneurysm, but in some patients no source of hemorrhage can be detected. More recent data showed increasing numbers of cases of spontaneous nonaneurysmal SAH (NASAH). The aim of this study was to analyze factors, especially the use of antithrombotic medications such as systemic anticoagulation or antiplatelet agents (aCPs), influencing the increasing numbers of cases of NASAH and the clinical outcome. METHODS Between 1999 and 2013, 214 patients who were admitted to the authors' institution suffered from NASAH, 14% of all patients with SAH. Outcome was assessed according to the modified Rankin Scale (mRS) at 6 months. Risk factors were identified based on the outcome. RESULTS The number of patients with NASAH increased significantly in the last 15 years of the study period. There was a statistically significant increase in the rate of nonperimesencephalic (NPM)-SAH occurrence and aCP use, while the proportion of elderly patients remained stable. Favorable outcome (mRS 0-2) was achieved in 85% of cases, but patients treated with aCPs had a significantly higher risk for an unfavorable outcome. Further analysis showed that elderly patients, and especially the subgroup with a Fisher Grade 3 bleeding pattern, had a high risk for an unfavorable outcome, whereas the subgroup of NPM-SAH without a Fisher Grade 3 bleeding pattern had a favorable outcome, similar to perimesencephalic (PM)-SAH. CONCLUSIONS Over the years, a significant increase in the number of patients with NASAH has been observed. Also, the rate of aCP use has increased significantly. Risk factors for an unfavorable outcome were age > 65 years, Fisher Grade 3 bleeding pattern, and aCP use. Both "PM-SAH" and "NPM-SAH without a Fisher Grade 3 bleeding pattern" had excellent outcomes. Patients with NASAH and a Fisher Grade 3 bleeding pattern had a significantly higher risk for an unfavorable outcome and death. Therefore, for further investigations, NPM-SAH should be stratified into patients with or without a Fisher Grade 3 bleeding pattern. Also, cases of spontaneous SAH should be stratified into NASAH and aneurysmal SAH.

Unfavourable outcomes are part and parcel of performing surgeries of any kind. Unfavourable outcomes are results of such work, which the patient and or the clinician does not like. This is an attempt to review various causes for unfavorable outcomes in orthognathic surgery and discuss them in detail. All causes for unfavorable outcomes may be classified as belonging to one of the following periods A) Pre- Treatment B) During treatment Pre-Treatment: In orthognathic surgery- as in any other discipline of surgery- which involves changes in both aesthetics and function, the patient motivation for seeking treatment is a very important input which may decide, whether the outcome is going to be favorable or not. Also, inputs in diagnosis and plan for treatment and its sequencing, involving the team of the surgeon and the orthodontist, will play a very important role in determining whether the outcome will be favorable. In other words, an unfavorable outcome may be predetermined even before the actual treatment process starts. During Treatment: Good treatment planning itself does not guarantee favorable results. The execution of the correct plan could go wrong at various stages which include, Pre-Surgical orthodontics, Intra and Post-Operative periods. A large number of these unfavorable outcomes are preventable, if attention is paid to detail while carrying out the treatment plan itself. Unfavorable outcomes in orthognathic surgery may be minimized If pitfalls are avoided both, at the time of treatment planning and execution.

Evidence for unfavorable outcomes of each type of aggressive variant papillary thyroid carcinoma (AV-PTC) is not clear because most previous studies are focused on tall cell variant (TCV) and did not control for other major confounding factors contributing to clinical outcomes. Retrospective cohort study. This study included 763 patients with classical PTC (cPTC) and 144 with AV-PTC, including TCV, columnar cell variant (CCV), and hobnail variants. Disease-free survival (DFS) and dynamic risk stratification (DRS) were compared after two-to-one propensity score matching by age, sex, tumor size, lymph node metastasis, and extrathyroidal extension. The AV-PTC group had significantly lower DFS rates than its matched cPTC group (HR=2.16, 95% CI 1.12-4.16, p=0.018). When TCV and CCV were evaluated separately, there was no significant differences in DFS and DRS between patients with TCV (n=121) and matched cPTC. However, CCV group (n=18) had significantly poorer DFS than matched cPTC group (HR=12.19, 95% CI 2.11-70.33, p=0.005). In DRS, there were significantly more patients with structural incomplete responses in CCV group compared by matched cPTC group (p=0.047). CCV was an independent risk factor for structural persistent/recurrent disease in multivariate analysis (HR, 4.28; 95% CI, 1.66-11.00, p=0.001). When other clinicopathological factors were similar, patients with TCV did not exhibit unfavorable clinical outcome whereas those with CCV had significantly poorer clinical outcome. Individualized therapeutic approach might be necessary for each type of AV-PTCs.

Enhanced blood levels of copeptin correlate with poor clinical outcomes after acute critical illness. This study aimed to compare the prognostic performances of plasma concentrations of copeptin and other biomarkers like myelin basic protein, glial fibrillary astrocyte protein, S100B, neuron-specific enolase, phosphorylated axonal neurofilament subunit H, Tau and ubiquitin carboxyl-terminal hydrolase L1 in severe traumatic brain injury. We recruited 102 healthy controls and 102 acute patients with severe traumatic brain injury. Plasma concentrations of these biomarkers were determined using enzyme-linked immunosorbent assay. Their prognostic predictive performances of 6-month mortality and unfavorable outcome (Glasgow Outcome Scale score of 1-3) were compared. Plasma concentrations of these biomarkers were statistically significantly higher in all patients than in healthy controls, in non-survivors than in survivors and in patients with unfavorable outcome than with favorable outcome. Areas under receiver operating characteristic curves of plasma concentrations of these biomarkers were similar to those of Glasgow Coma Scale score for prognostic prediction. Except plasma copeptin concentration, other biomarkers concentrations in plasma did not statistically significantly improve prognostic predictive value of Glasgow Coma Scale score. Copeptin levels may be a useful tool to predict long-term clinical outcomes after severe traumatic brain injury and have a potential to assist clinicians. Copyright © 2014 Elsevier Inc.

Between 1988 and 1995, 73 adolescent athletes treated with the Boston Overlap Brace for spondylolysis were reviewed to evaluate improvement in pain score and activity level. A favorable clinical outcome was achieved in 80%. Girls and boys who participated in high-risk sports were five times more likely to have an unfavorable clinical outcome than those who participated in low-risk sports (odds ratio = 5, 95% confidence interval = 2.4-7.5, P = .003). In addition, acute onset of pain and hamstring tightness were associated with a worse outcome. Athletes with symptomatic spondylolysis treated with an antilordotic brace can expect improvement in their clinical course and return to sports participation in 4-6 weeks.

It is unclear whether decompressive craniectomy improves the functional outcome in patients with severe traumatic brain injury and refractory raised intracranial pressure. From December 2002 through April 2010, we randomly assigned 155 adults with severe diffuse traumatic brain injury and intracranial hypertension that was refractory to first-tier therapies to undergo either bifrontotemporoparietal decompressive craniectomy or standard care. The original primary outcome was an unfavorable outcome (a composite of death, vegetative state, or severe disability), as evaluated on the Extended Glasgow Outcome Scale 6 months after the injury. The final primary outcome was the score on the Extended Glasgow Outcome Scale at 6 months. Patients in the craniectomy group, as compared with those in the standard-care group, had less time with intracranial pressures above the treatment threshold (P<0.001), fewer interventions for increased intracranial pressure (P<0.02 for all comparisons), and fewer days in the intensive care unit (ICU) (P<0.001). However, patients undergoing craniectomy had worse scores on the Extended Glasgow Outcome Scale than those receiving standard care (odds ratio for a worse score in the craniectomy group, 1.84; 95% confidence interval [CI], 1.05 to 3.24; P=0.03) and a greater risk of an unfavorable outcome (odds ratio, 2.21; 95% CI, 1.14 to 4.26; P=0.02). Rates of death at 6 months were similar in the craniectomy group (19%) and the standard-care group (18%). In adults with severe diffuse traumatic brain injury and refractory intracranial hypertension, early bifrontotemporoparietal decompressive craniectomy decreased intracranial pressure and the length of stay in the ICU but was associated with more unfavorable outcomes.

High-level MYCN amplification (MNA) is associated with poor outcome and unfavorable clinical and biological features in patients with neuroblastoma. To the authors' knowledge, less is known regarding these associations in patients with low-level MYCN copy number increases. In this retrospective study, the authors classified patients has having tumors with MYCN wild-type tumors, MYCN gain (2-4-fold increase in MYCN signal compared with the reference probe), or MNA (>4-fold increase). Tests of trend were used to investigate ordered associations between MYCN copy number category and features of interest. Log-rank tests and Cox models compared event-free survival and overall survival by subgroup. Among 4672 patients, 3694 (79.1%) had MYCN wild-type tumors, 133 (2.8%) had MYCN gain, and 845 (18.1%) had MNA. For each clinical/biological feature, the percentage of patients with an unfavorable feature was lowest in the MYCN wild-type category, intermediate in the MYCN gain category, and highest in the MNA category (P<.0001), except for 11q aberration, for which the highest rates were in the MYCN gain category. Patients with MYCN gain had inferior event-free survival and overall survival compared with those with MYCN wild-type. Among patients with high-risk disease, MYCN gain was associated with the lowest response rate after chemotherapy. Patients with non-stage 4 disease (according to the International Neuroblastoma Staging System) and patients with non-high-risk disease with MYCN gain had a significantly increased risk for death, a finding confirmed on multivariable testing. Increasing MYCN copy number is associated with an increasingly higher rate of unfavorable clinical/biological features, with 11q aberration being an exception. Patients with MYCN gain appear to have inferior outcomes, especially in otherwise more favorable groups. Cancer 2017;123:4224-4235. © 2017 American Cancer Society. © 2017 American Cancer Society.

We evaluated the influence of post-rewarming temperature management (PRTM) on post-rewarming fever development and determined the association between the temperature in the immediate post-targeted temperature management (TTM) period and outcomes. This retrospective observational study included consecutive adult cardiac arrest survivors treated with TTM from January 2008 to December 2013. Beginning in August 2010, our institution implemented a PRTM protocol involving continued use of temperature management device to maintain normothermia during the first 24h after rewarming. The outcomes were in-hospital mortality and neurologic outcome at discharge. We evaluated the effect on clinical outcomes of post-rewarming fever defined at a temperature over 38 °C within 48 h after rewarming. Of 277 included patients, 55.2% underwent PRTM. The incidence of post-rewarming fever did not differ between the PRTM and no-PRTM groups (odds ratio [OR] 0.963, confidence interval [CI] 0.519, 1.787). Post-rewarming fever was associated with decreased in-hospital mortality (OR 0.243, CI 0.110, 0.534) and decreased rate of unfavorable neurologic outcome (OR 0.312, CI 0.182, 0.534). During 48 h following rewarming, mean temperature was 36.5 °C (36.2-36.8 °C), and peak temperature was 37.5 °C (36.8-38.1 °C). On multivariate analyses, lower mean temperature was associated with increased in-hospital mortality (OR 0.099, CI 0.037, 0.262) and unfavorable neurologic outcome (OR 0.071, CI 0.026, 0.193). It appeared that PRTM did not prevent post-rewarming fever development. Post-rewarming fever was associated with favorable outcomes while lower body temperature after rewarming was associated with unfavorable outcomes. Our results require further confirmation by larger prospective studies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Serratia marcescens is a rare pathogen of central nervous system infections. This study was to investigate the epidemiology, prognostic factors, and treatment outcomes of S. marcescens meningitis. This retrospective analysis included 33 patients with culture-proven S. marcescens meningitis hospitalized between January 2000 and June 2011. Of the 33 patients enrolled, only one did not receive neurosurgery before the onset of S. marcescens meningitis. Patients with S. marcescens meningitis had higher ratios of brain solid tumors (54.5%) and neurosurgery (97.0%) with a mortality rate of 15.2%. The mean interval between the first neurosurgical procedure and the diagnosis of meningitis was 17.1 days (range, 4-51 days). Only one third-generation cephalosporin-resistant S. marcescens isolate was recovered from the patients' cerebrospinal fluid (CSF) specimens. Compared with the favorable outcome group (n = 20), the unfavorable outcome group (n = 13) had a higher percentage of brain solid tumors, more intensive care unit stays, and higher Sequential Organ Failure Assessment score, CSF lactate and serum C-reactive protein concentrations at diagnosis of meningitis. Under the multiple regression analysis, CSF lactate concentration ≥2-fold the upper limit of normal (ULN) was independently associated with unfavorable outcomes (odds ratio, 7.20; 95% confidence interval, 1.08-47.96; p = 0.041). S. marcescens meningitis is highly associated with neurosurgical procedures for brain solid tumors. CSF lactate concentration ≥2x ULN may predict an unfavorable outcome. Its mortality is not high and empiric treatment with parenteral third-generation cephalosporins may have a satisfactory clinical response. Copyright © 2012. Published by Elsevier B.V.

For the postoperative follow-up in pediatric patients with Moyamoya disease, it is essential to evaluate the degree of neovascularization status. Our aim was to quantitatively assess the neovascularization status after bypass surgery in pediatric Moyamoya disease by using color-coded digital subtraction angiography. Time-attenuation intensity curves were generated at ROIs corresponding to surgical flap sites from color-coded DSA images of the common carotid artery, internal carotid artery, and external carotid artery angiograms obtained pre- and postoperatively in 32 children with Moyamoya disease. Time-to-peak and area under the curve values were obtained. Postoperative changes in adjusted time-to-peak (ΔTTP) and ratios of adjusted area under the curve changes (ΔAUC ratio) of common carotid artery, ICA, and external carotid artery angiograms were compared across clinical and angiographic outcome groups. To analyze diagnostic performance, we categorized clinical outcomes into favorable and unfavorable groups. The ΔTTP at the common carotid artery increased among clinical and angiographic outcomes, in that order, with significant differences (P = .003 and .005, respectively). The ΔAUC ratio at the common carotid artery and external carotid artery also increased, in that order, among clinical and angiographic outcomes with a significant difference (all, P = .000). The ΔAUC ratio of ICA showed no significant difference among clinical and angiographic outcomes (P = .418 and .424, respectively). The ΔTTP for the common carotid artery of >1.27 seconds and the ΔAUC ratio of >33.5% for the common carotid artery and 504% for the external carotid artery are revealed as optimal cutoff values between favorable and unfavorable groups. Postoperative changes in quantitative values obtained with color-coded DSA software showed a significant correlation with outcome scores and can be used as objective parameters for predicting the outcome in pediatric Moyamoya disease, with an additional cutoff value calculated through the receiver operating characteristic curve. © 2016 by American Journal of Neuroradiology.

Predicted Unfavorable Neurologic Outcome Is Overestimated by the Marshall Computed Tomography Score, Corticosteroid Randomization After Significant Head Injury (CRASH), and International Mission for Prognosis and Analysis of Clinical Trials in Traumatic Brain Injury (IMPACT) Models in Patients with Severe Traumatic Brain Injury Managed with Early Decompressive Craniectomy.

Traumatic brain injury (TBI) is of public health interest and produces significant mortality and disability in Colombia. Calculators and prognostic models have been developed to establish neurologic outcomes. We tested prognostic models (the Marshall computed tomography [CT] score, International Mission for Prognosis and Analysis of Clinical Trials in Traumatic Brain Injury (IMPACT), and Corticosteroid Randomization After Significant Head Injury) for 14-day mortality, 6-month mortality, and 6-month outcome in patients with TBI at a university hospital in Colombia. A 127-patient cohort with TBI was treated in a regional trauma center in Colombia over 2 years and bivariate and multivariate analyses were used. Discriminatory power of the models, their accuracy, and precision was assessed by both logistic regression and area under the receiver operating characteristic curve (AUC). Shapiro-Wilk, χ 2 , and Wilcoxon test were used to compare real outcomes in the cohort against predicted outcomes. The group's median age was 33 years, and 84.25% were male. The injury severity score median was 25, and median Glasgow Coma Scale motor score was 3. Six-month mortality was 29.13%. Six-month unfavorable outcome was 37%. Mortality prediction by Marshall CT score was 52.8%, P = 0.104 (AUC 0.585; 95% confidence interval [CI] 0 0.489-0.681), the mortality prediction by CRASH prognosis calculator was 59.9%, P < 0.001 (AUC 0.706; 95% CI 0.590-0.821), and the unfavorable outcome prediction by IMPACT was 77%, P < 0.048 (AUC 0.670; 95% CI 0.575-0.763). In a university hospital in Colombia, the Marshall CT score, IMPACT, and Corticosteroid Randomization After Significant Head Injury models overestimated the adverse neurologic outcome in patients with severe head trauma.

Evidence suggests that patients are generally accepting of their enrollment in trials for emergency care conducted under exception from informed consent. It is unknown whether individuals with more severe initial injuries or worse clinical outcomes have different perspectives. Determining whether these differences exist may help to structure post-enrollment interactions. Primary clinical data from the Progesterone for the Treatment of Traumatic Brain Injury trial were matched to interview data from the Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study. Answers to three key questions from Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study were analyzed in the context of enrolled patients' initial injury severity (initial Glasgow Coma Scale and Injury Severity Score) and principal clinical outcomes (Extended Glasgow Outcome Scale and Extended Glasgow Outcome Scale relative to initial injury severity). The three key questions from Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study addressed participants' general attitude toward inclusion in the Progesterone for the Treatment of Traumatic Brain Injury trial (general trial inclusion), their specific attitude toward being included in Progesterone for the Treatment of Traumatic Brain Injury trial under the exception from informed consent (personal exception from informed consent enrollment), and their attitude toward the use of exception from informed consent in the Progesterone for the Treatment of Traumatic Brain Injury trial in general (general exception from informed consent enrollment). Qualitative analysis of interview transcripts was performed to provide contextualization and to determine the extent to which respondents framed their attitudes in terms of clinical experience. Clinical data from Progesterone for the Treatment of Traumatic Brain Injury trial were available for all 74 patients represented in the Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study (including 46 patients for whom the surrogate was interviewed due to the patient's cognitive status or death). No significant difference was observed regarding acceptance of general trial inclusion or acceptance of general exception from informed consent enrollment between participants with favorable neurological outcomes and those with unfavorable outcomes relative to initial injury. Agreement with personal enrollment in Progesterone for the Treatment of Traumatic Brain Injury trial under exception from informed consent, however, was significantly higher among participants with favorable outcomes compared to those with unfavorable outcomes (89% vs 59%, p = 0.003). There was also a statistically significant relationship between more severe initial injury and increased acceptance of personal exception from informed consent enrollment ( p = 0.040) or general exception from informed consent use ( p = 0.034) in Progesterone for the Treatment of Traumatic Brain Injury trial. Many individuals referenced personal experience as a basis for their attitudes, but these references were not used to support negative views. Patients and surrogates of patients with unfavorable clinical outcomes were somewhat less accepting of their own inclusion in the Progesterone for the Treatment of Traumatic Brain Injury trial under exception from informed consent than were patients or surrogates of patients with favorable clinical outcomes. These findings suggest a need to identify optimal strategies for communicating with patients and their surrogates regarding exception from informed consent enrollment when clinical outcomes are poor.

A large number of patients resuscitated for primary cardiac arrest arrive in the intensive care unit (ICU) with a body temperature < 35.0 degrees C. The aim of this observational cohort study was to determine the association between ICU admission temperature and neurological outcome in this patient group. Demographics and parameters influencing neurological outcome were retrieved from the charts of all patients resuscitated for primary cardiac arrest and treated with induced mild hypothermia in our ICU from January 2006 until January 2008. Patients were divided into two groups according to their body temperature on ICU admission: a hypothermia group (< 35.0 degrees C) and a non-hypothermia group (>or=35.0 degrees C). Neurological outcome after six months was assessed by means of the Glasgow Outcome Score (GOS), with GOS 1 to 3 defined as unfavorable and GOS 4 to 5 as favorable. A logistic regression model was used to analyze the influence of the different parameters on neurological outcome. The data of 105 consecutive patients resuscitated for primary cardiac arrest and treated with induced mild hypothermia were analyzed. Median ICU admission temperature was 35.1 degrees C (interquartile range (IQR) 34.3 to 35.7). After six months, 61% of the patients had an unfavorable outcome (59% died and 2% were severely disabled), whereas 39% had a favorable outcome (moderate disability or good recovery). Among patients with spontaneous hypothermia on ICU admission, the percentage with unfavorable outcome was higher (69% versus 50%, P = 0.05). Logistic regression showed that age, acute physiology and chronic health evaluation (APACHE) II and sequential organ failure assessment (SOFA) scores and spontaneous hypothermia on ICU admission all had an increased odds ratio (OR) for an unfavorable outcome after six months. Spontaneous hypothermia had the strongest association with unfavorable outcome (OR 2.6, 95% CI (confidence interval) 1.1 to 5.9), which became even stronger after adjustment for age, presenting heart rhythm, APACHE II and SOFA scores (OR 3.8, CI 1.3 to 11.0). In this observational cohort study, spontaneous hypothermia on ICU admission was the strongest predictor of an unfavorable neurological outcome in patients resuscitated for primary cardiac arrest.

The objective of the study is to test whether multimodal magnetic resonance imaging can provide a reliable outcome prediction of the clinical status, focusing on consciousness at 1 year after severe traumatic brain injury (TBI). Single center prospective cohort with consecutive inclusions. Critical Care Neurosurgical Unit of a university hospital. Forty-three TBI patients not responding to simple orders after sedation cessation and 15 healthy controls. A multimodal magnetic resonance imaging combining morphologic sequences, diffusion tensor imaging (DTI), and H proton magnetic resonance spectroscopy (MRS) was performed 24 +/- 11 days after severe TBI. The ability of DTI and MRS to predict 1-year outcome was assessed by linear discriminant analysis (LDA). Robustness of the classification was tested using a bootstrap procedure. Fractional anisotropy (FA) was computed as the mean of values at discrete brain sites in the infratentorial and supratentorial regions. The N-acetyl aspartate/creatine (NAA/Cr) ratio was measured in the thalamus, lenticular nucleus, insular cortex, occipital periventricular white matter, and pons. After 1 year, 19 (44%) patients had unfavorable outcomes (death, persistent vegetative state, or minimally conscious state) and 24 (56%) favorable outcomes (normal consciousness with or without functional impairments). Analysis of variance was performed to compare FA and NAA/Cr in the two outcome groups and controls. FA and MRS findings showed highly significant differences between the outcome groups, with significant variables by LDA being supratentorial FA, NAA/Cr (pons), NAA/Cr (thalamus), NAA/Cr (insula), and infratentorial FA. LDA of combined FA and MRS data clearly separated the unfavorable outcome, favorable outcome, and control groups, with no overlap. Unfavorable outcome was predicted with up to 86% sensitivity and 97% specificity; these values were better than those obtained with DTI or MRS alone. FA and NAA/Cr hold potential as quantitative outcome-prediction tools at the subacute phase of TBI.

Background. Antibiotic-tolerant bacterial persistence prevents treatment shortening in drug-susceptible tuberculosis, and accumulation of intracellular lipid bodies has been proposed to identify a persister phenotype of Mycobacterium tuberculosis cells. In Malawi, we modeled bacillary elimination rates (BERs) from sputum cultures and calculated the percentage of lipid body–positive acid-fast bacilli (%LB + AFB) on sputum smears. We assessed whether these putative measurements of persistence predict unfavorable outcomes (treatment failure/relapse). Methods. Adults with pulmonary tuberculosis received standard 6-month therapy. Sputum samples were collected during the first 8 weeks for serial sputum colony counting (SSCC) on agar and time-to positivity (TTP) measurement in mycobacterial growth indicator tubes. BERs were extracted from nonlinear and linear mixed-effects models, respectively, fitted to these datasets. The %LB + AFB counts were assessed by fluorescence microscopy. Patients were followed until 1 year posttreatment. Individual BERs and %LB + AFB counts were related to final outcomes. Results. One hundred and thirty-three patients (56% HIV coinfected) participated, and 15 unfavorable outcomes were reported. These were inversely associated with faster sterilization phase bacillary elimination from the SSCC model (odds ratio [OR], 0.39; 95% confidence interval [CI], .22–.70) and a faster BER from the TTP model (OR, 0.71; 95% CI, .55–.94). Higher %LB + AFB counts on day 21–28 were recorded in patients who suffered unfavorable final outcomes compared with those who achieved stable cure (P = .008). Conclusions. Modeling BERs predicts final outcome, and high %LB + AFB counts 3–4 weeks into therapy may identify a persister bacterial phenotype. These methods deserve further evaluation as surrogate endpoints for clinical trials. PMID:25778753

Evaluate the result of intracranial aneurysm surgery in Maharaj Nakorn Chiang Mai Hospital. A retrospective study ofpatients who underwent surgery for intracranial aneurysms between 2003 and 2007. The patients'age, gender, signs and symptoms, CT brain findings, Subarachnoid hemorrhage (SAH), World Federation of Neurosurgical Society grading (WFNS), and aneurysm location were studied and correlated with outcome after surgery. Two hundred twenty five patients ofintracranial aneurysm were operated on between 2003 and 2007. Two hundred nine patients (92%) had anterior circulation aneurysms and 18 (8%) had posterior circulation aneurysms. The outcome, as evaluated by Glasgow Outcome Scale (GOS), showed good recovery and moderate disability patients (142, 62.9%) were classified as favorable outcome group whereas patients with severe disability, vegetative state, and dead (83, 36.9%) were classified as unfavorable outcome. According to WFNS grading, the patients with unruptured aneurysm and WFNS grade 1-2 had favorable outcome in 116 patients (78.37%) and unfavorable outcome in 32 patients (21.62%). Whereas the patients with WFNS grade 3-5 had favorable outcome in 32 patients (33.76%) and unfavorable outcome in 51 patients (66.23%). This study of 225 cases revealed 142 cases with favorable outcome and 83 cases with unfavorable outcome. Factors that affected the outcome were WFNS grading and age.

Objective: In bacterial meningitis, a decreased level of consciousness is predictive for unfavorable outcome, but the clinical features and outcome in patients presenting with a minimal score on the Glasgow Coma Scale are unknown. Methods: We assessed the incidence, clinical characteristics, and outcome of patients with bacterial meningitis presenting with a minimal score on the Glasgow Coma Scale from a nationwide cohort study of adults with community-acquired bacterial meningitis in the Netherlands from 2006 to 2012. Results: Thirty of 1,083 patients (3%) presented with a score of 3 on the Glasgow Coma Scale. In 22 of 30 patients (73%), the minimal Glasgow Coma Scale score could be explained by use of sedative medication or complications resulting from meningitis such as seizures, cerebral edema, and hydrocephalus. Systemic (86%) and neurologic (47%) complications occurred frequently, leading to a high proportion of patients with unfavorable outcome (77%). However, 12 of 30 patients (40%) survived and 7 patients (23%) had a good functional outcome, defined as a score of 5 on the Glasgow Outcome Scale. Patients presenting with a minimal Glasgow Coma Scale score on admission and bilaterally absent pupillary light responses, bilaterally absent corneal reflexes, or signs of septic shock on admission all died. Conclusions: Patients with community-acquired bacterial meningitis rarely present with a minimal score on the Glasgow Coma Scale, but this condition is associated with high rates of morbidity and mortality. However, 1 out of 5 of these severely ill patients will make a full recovery, stressing the continued need for aggressive supportive care in these patients. PMID:25340065

The study aimed to test the hypothesis that computer-based calculation of malnutrition risk may enhance the ability to identify pediatric patients at malnutrition-related risk for an unfavorable outcome. The Pediatric Digital Scaled MAlnutrition Risk screening Tool (PeDiSMART), incorporating the World Health Organization (WHO) growth reference data and malnutrition-related parameters, was used. This was a prospective cohort study of 500 pediatric patients aged 1 month to 17 years. Upon admission, the PeDiSMART score was calculated and anthropometry was performed. Pediatric Yorkhill Malnutrition Score (PYMS), Screening Tool Risk on Nutritional Status and Growth (STRONGkids), and Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) malnutrition screening tools were also applied. PeDiSMART's association with the clinical outcome measures (weight loss/nutrition support and hospitalization duration) was assessed and compared with the other screening tools. The PeDiSMART score was inversely correlated with anthropometry and bioelectrical impedance phase angle (BIA PhA). The score's grading scale was based on BIA Pha quartiles. Weight loss/nutrition support during hospitalization was significantly independently associated with the malnutrition risk group allocation on admission, after controlling for anthropometric parameters and age. Receiver operating characteristic curve analysis showed a sensitivity of 87% and a specificity of 75% and a significant area under the curve, which differed significantly from that of STRONGkids and STAMP. In the subgroups of patients with PeDiSMART-based risk allocation different from that based on the other tools, PeDiSMART allocation was more closely related to outcome measures. PeDiSMART, applicable to the full age range of patients hospitalized in pediatric departments, graded according to BIA PhA, and embeddable in medical electronic records, enhances efficacy and reproducibility in identifying pediatric patients at malnutrition-related risk for an unfavorable outcome. Patient allocation according to the PeDiSMART score on admission is associated with clinical outcome measures. © 2014 American Society for Parenteral and Enteral Nutrition.

Central autonomic dysfunction increases stroke morbidity and mortality. We aimed to investigate whether poststroke autonomic dysfunction graded by Ewing battery can predict clinical outcome. In this prospective observational study, we assessed autonomic function of ischemic stroke patients within 7 days from symptom onset by Ewing battery. On the basis of the magnitude of autonomic dysfunction, we stratified patients into significant (definite, severe, or atypical) or minor (normal or early) autonomic function impairment groups and correlated the impairment with the 3-month modified Rankin Scale score (good outcome: modified Rankin Scale score 0≈2; poor outcome: modified Rankin Scale score 3≈6). Among the 150 patients enrolled (mean age, 66.4±9.9 years; 70.7% males), minor autonomic dysfunction was identified in 36 patients (24.0%), and significant autonomic dysfunction was identified in 114 patients (76.0%) based on Ewing battery. In 3 months, a poor functional outcome was found in 32.5% of significant group patients compared with 13.9% in the minor group ( P =0.031). Crude odds ratios of the magnitude of autonomic dysfunction and 3-month unfavorable functional outcome after acute ischemic stroke were 2.979 (95% confidence interval, 1.071-8.284; P =0.036). After adjusting for confounding variables with statistical significance between the 2 functional outcome subgroups identified in univariate analysis (including sex and National Institutes of Health Stroke Scale score on admission), the magnitude of autonomic dysfunction still independently predicted an unfavorable outcome, with an odds ratio of 3.263 (95% confidence interval, 1.141-9.335; P =0.027). Autonomic dysfunction gauged by Ewing battery predicts poor functional outcome after acute ischemic stroke. © 2017 American Heart Association, Inc.

To reveal characteristics of spontaneous intracerebral hemorrhage (sICH) in a plateau area based on the Tibetan population. Data of Tibetan and Han patients (control group) with sICH treated at our center from January 2013 to April 2017 were retrospectively reviewed. A total of 122 Tibetan and 927 Han patients were included. Compared with Han patients, Tibetan patients were older (54.7±11.2 VS 50.9±18.3 years, P=0.027), exhibited higher ratios of males (73.8% VS 55.0%, P<0.001), overweight patients (22.1% VS 13.1%, P=0.007) and smokers (36.9% VS 20.5%, P<0.001), had a higher concentration of hemoglobin (163.7±17.6 VS 134.8±20.2 g/L, P<0.001) and included a higher number of patients with hypertension (83.6% VS 60.5%, P<0.001), diabetes mellitus (19.2% VS 9.3%, P=0.002) and prior hemorrhagic stroke (9.0% VS 2.0%, P<0.001). Tibetan patients also experienced more brain stem hemorrhage (11.5% VS 5.1%, P=0.039) in the infratentorial region and had a higher risk of in-hospital complications due to hematoma enlargement (20.5% VS 10.4%, P=0.002) and cerebral infarction (59.0% VS 9.7%, P<0.001). During a 6-month follow-up period, they had higher rates of unfavorable outcomes and case mortality (P<0.05). A multivariable analysis adjusted for confounding factors revealed that the Tibetan race was positively associated with unfavorable clinical outcomes in sICH patients (P<0.05). Tibetan sICH patients from the plateau area presented unique characteristics in their baseline measurements, incidence of comorbidities, hematoma location, risk of in-hospital complications and clinical outcomes compared with Han patients. The Tibetan race was positively associated with unfavorable 6-month outcomes in ICH patients. Copyright © 2018 Elsevier Inc. All rights reserved.

Background Traumatic brain injury (TBI) is a complex disorder that is traditionally stratified based on clinical signs and symptoms. Recent imaging and molecular biomarker innovations provide unprecedented opportunities for improved TBI precision medicine, incorporating patho-anatomical and molecular mechanisms. Complete integration of these diverse data for TBI diagnosis and patient stratification remains an unmet challenge. Methods and findings The Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Pilot multicenter study enrolled 586 acute TBI patients and collected diverse common data elements (TBI-CDEs) across the study population, including imaging, genetics, and clinical outcomes. We then applied topology-based data-driven discovery to identify natural subgroups of patients, based on the TBI-CDEs collected. Our hypothesis was two-fold: 1) A machine learning tool known as topological data analysis (TDA) would reveal data-driven patterns in patient outcomes to identify candidate biomarkers of recovery, and 2) TDA-identified biomarkers would significantly predict patient outcome recovery after TBI using more traditional methods of univariate statistical tests. TDA algorithms organized and mapped the data of TBI patients in multidimensional space, identifying a subset of mild TBI patients with a specific multivariate phenotype associated with unfavorable outcome at 3 and 6 months after injury. Further analyses revealed that this patient subset had high rates of post-traumatic stress disorder (PTSD), and enrichment in several distinct genetic polymorphisms associated with cellular responses to stress and DNA damage (PARP1), and in striatal dopamine processing (ANKK1, COMT, DRD2). Conclusions TDA identified a unique diagnostic subgroup of patients with unfavorable outcome after mild TBI that were significantly predicted by the presence of specific genetic polymorphisms. Machine learning methods such as TDA may provide a robust method for patient stratification and treatment planning targeting identified biomarkers in future clinical trials in TBI patients.

Low levels of Stat5a protein in breast cancer are associated with tumor progression and unfavorable clinical outcomes

PubMed Central

2012-01-01

Introduction Signal transducer and activator of transcripton-5a (Stat5a) and its close homologue, Stat5b, mediate key physiological effects of prolactin and growth hormone in mammary glands. In breast cancer, loss of nuclear localized and tyrosine phosphorylated Stat5a/b is associated with poor prognosis and increased risk of antiestrogen therapy failure. Here we quantify for the first time levels of Stat5a and Stat5b over breast cancer progression, and explore their potential association with clinical outcome. Methods Stat5a and Stat5b protein levels were quantified in situ in breast-cancer progression material. Stat5a and Stat5b transcript levels in breast cancer were correlated with clinical outcome in 936 patients. Stat5a protein was further quantified in four archival cohorts totaling 686 patients with clinical outcome data by using multivariate models. Results Protein levels of Stat5a but not Stat5b were reduced in primary breast cancer and lymph node metastases compared with normal epithelia. Low tumor levels of Stat5a but not Stat5b mRNA were associated with poor prognosis. Experimentally, only limited overlap between Stat5a- and Stat5b-modulated genes was found. In two cohorts of therapy-naïve, node-negative breast cancer patients, low nuclear Stat5a protein levels were an independent marker of poor prognosis. Multivariate analysis of two cohorts treated with antiestrogen monotherapy revealed that low nuclear Stat5a levels were associated with a more than fourfold risk of unfavorable outcome. Conclusions Loss of Stat5a represents a new independent marker of poor prognosis in node-negative breast cancer and may be a predictor of response to antiestrogen therapy if validated in randomized clinical trials.

The use of hip arthroscopy continues to expand. Understanding potential pitfalls and complications associated with hip arthroscopy is paramount to optimizing clinical outcomes and minimizing unfavorable results. Potential pitfalls and complications are associated with preoperative factors such as patient selection, intraoperative factors such as iatrogenic damage, traction-related complications, inadequate correction of deformity, and nerve injury, or postoperative factors such as poor rehabilitation. This article outlines common factors that contribute to less-than-favorable outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

Bacteremia caused by MRSA with reduced vancomycin susceptibility (MRSA-RVS) frequently resulted in treatment failure and mortality. The relation of bacterial factors and unfavorable outcomes remains controversial. We retrospectively reviewed clinical data of patients with bacteremia caused by MRSA with vancomycin MIC = 2 mg/L from 2009 to 2012. The significance of bacterial genotypes, agr function and heterogeneous vancomycin-intermediate S. aureus (hIVSA) phenotype in predicting outcomes were determined after clinical covariates adjustment with multivariate analysis. A total of 147 patients with mean age of 63.5 (±18.1) years were included. Seventy-nine (53.7%) patients failed treatment. Forty-seven (31.9%) patients died within 30 days of onset of MRSA bacteremia. The Charlson index, Pitt bacteremia score and definitive antibiotic regimen were independent factors significantly associated with either treatment failure or mortality. The hVISA phenotype was a potential risk factor predicting treatment failure (adjusted odds ratio 2.420, 95% confidence interval 0.946-6.191, P = 0.0652). No bacterial factors were significantly associated with 30-day mortality. In conclusion, the comorbidities, disease severity and antibiotic regimen remained the most relevant factors predicting treatment failure and 30-day mortality in patients with MRSA-RVS bacteremia. hIVSA phenotype was the only bacterial factor potentially associated with unfavorable outcome in this cohort.

Cardiopulmonary resuscitation and mild therapeutic hypothermia (MTH) have improved neurological outcomes after sudden cardiac arrest, but the factors affecting favorable neurological outcome remain unclear. The aim of this study was to clarify these factors in patients in cardiac arrest treated with MTH. Forty-six consecutive patients (mean age, 59.4 ± 14.3 years; 37 men and 9 women) who had had cardiogenic cardiac arrest from January 2008 through December 2011, including cases that were and were not shockable, were enrolled in this study, and the factors affecting favorable neurological outcome were retrospectively investigated. The interval from cardiac arrest to cardiopulmonary resuscitation, the return of spontaneous circulation (ROSC), the start of MTH, and the attaining of the target temperature were retrieved from the medical records. The relationship between the neurological outcome and clinical findings, including the causes of cardiac arrest and vital signs before MTH, were also investigated. Blood pressure and body temperature before MTH were higher, the interval from cardiac arrest to ROSC was shorter, and MTH was started earlier in patients with favorable neurological outcomes than in those with unfavorable outcomes. A multivariate logistic regression model revealed that the presence of prehospital ROSC was predictive of a favorable neurological outcome. In addition, renal failure during MTH occurred more frequently in patients with unfavorable neurological outcomes. MTH is associated with favorable neurological outcomes after sudden cardiac arrest, including those with non-shockable rhythms, especially in patients with prehospital ROSC.

Paroxysmal sympathetic hyperactivity (PSH) is a less-known complication of traumatic brain injury (TBI). This study was done to assess the clinical features and outcome of patients who develop PSH following severe TBI. A prospective observational study was done on patients, admitted in the intensive care unit, for treatment of severe TBI. The clinical characteristics and outcome of patients, with and without PSH, was compared. At the time of discharge, patients were assessed with the Disability Rating Scale (DRS), and at 6 months with the Glasgow Outcome Score Extended (GOSE). The incidence of PSH was 8 % (29/343). Tachycardia, hypertension, and sweating were seen in all of the patients. Tachypnea was seen in 24 (82.8 %), hyperthermia in 28 (96.6 %), and posturing in 13 (44.8 %) patients. Thirteen (44.8 %) patients had all six symptoms of PSH. Follow-up data were available for 23 (79.3 %) patients. At the end of 6 months, 14 (60.9 %) patients had died, seven (30.4 %) were severely disabled, and two (8.7 %) were moderately disabled. There was a significant correlation of GOSE with the number of symptoms of PSH (Spearman's rho = 0.502, p = 0.015). The patients with PSH had significantly higher DRS scores at discharge, 25.3 vs. 19.9, p < 0.001; higher mortality at 6 months 60.9 vs. 30.4 %, p < 0.001; and higher proportions with unfavorable outcome. Presence of PSH in patients with severe TBI was associated with prolonged hospital stay, poorer DRS at discharge, more deaths, and unfavorable outcome. The number of symptoms of PSH had a significant effect on outcome at 6 months.

To compare visual acuity at 6 years of age in eyes that received early treatment for high-risk prethreshold retinopathy of prematurity (ROP) with conventionally managed eyes. Infants with symmetrical, high-risk prethreshold ROP (n = 317) had one eye randomized to earlier treatment at high-risk prethreshold disease and the other eye managed conventionally, treated if ROP progressed to threshold severity. For asymmetric cases (n = 84), the high-risk prethreshold eye was randomized to either early treatment or conventional management. The main outcome measure was ETDRS visual acuity measured at 6 years of age by masked testers. Retinal structure was assessed as a secondary outcome. Analysis of all subjects with high-risk prethreshold ROP showed no statistically significant benefit for early treatment (24.3% vs 28.6% [corrected] unfavorable outcome; P = .15). Analysis of 6-year visual acuity results according to the Type 1 and 2 clinical algorithm showed a benefit for Type 1 eyes (25.1% vs 32.8%; P = .02) treated early but not Type 2 eyes (23.6% vs 19.4%; P = .37). Early-treated eyes showed a significantly better structural outcome compared with conventionally managed eyes (8.9% vs 15.2% unfavorable outcome; P < .001), with no greater risk of ocular complications. Early treatment for Type 1 high-risk prethreshold eyes improved visual acuity outcomes at 6 years of age. Early treatment for Type 2 high-risk prethreshold eyes did not. Application to Clinical Practice Type 1 eyes, not Type 2 eyes, should be treated early. These results are particularly important considering that 52% of Type 2 high-risk prethreshold eyes underwent regression of ROP without requiring treatment.

Many people believe that the moon has an influence on daily life, and some even request elective surgery dates depending on the moon calendar. The aim of this study was to assess the influence of 'unfavorable' lunar or zodiac constellations on perioperative complications and outcome in elective surgery for degenerative disc disease. Retrospective database analysis including 924 patients. Using uni- and multivariate logistic regression, the likelihood for intraoperative complications and re-do surgeries as well as the clinical outcomes at 4 weeks was analyzed for surgeries performed during the waxing moon, full moon, and dates when the moon passed through the zodiac sign 'Leo.' In multivariate analysis, patients operated on during the waxing moon were 1.54 times as likely as patients who were operated on during the waning moon to suffer from an intraoperative complication (OR 1.54, 95 % CI 1.07-2.21, p = 0.019). In contrast, there was a trend toward fewer re-do surgeries for surgery during the waxing moon (OR 0.51, 95 % CI 0.23-1.16, p = 0.109), while the 4-week responder status was similar (OR 0.73, 95 % CI 0.47-1.14, p = 0.169). A full moon and the zodiac sign Leo did not increase the likelihood for complications, re-do surgeries or unfavorable outcomes. We found no influence of 'unfavorable' lunar or zodiac constellations on the 4-week responder status or the revision rate that would justify a moon calendar-based selection approach to elective spine surgery dates. However, the fact that patients undergoing surgery during the waxing moon were more likely to suffer from an intraoperative complication is a surprising curiosity and defies our ability to find a rational explanation.

Dichotomous endpoints in clinical trials have only two possible outcomes, either directly or via categorization of an ordinal or continuous observation. It is common to have missing data for one or more visits during a multi-visit study. This paper presents a closed form method for sensitivity analysis of a randomized multi-visit clinical trial that possibly has missing not at random (MNAR) dichotomous data. Counts of missing data are redistributed to the favorable and unfavorable outcomes mathematically to address possibly informative missing data. Adjusted proportion estimates and their closed form covariance matrix estimates are provided. Treatment comparisons over time are addressed with Mantel-Haenszel adjustment for a stratification factor and/or randomization-based adjustment for baseline covariables. The application of such sensitivity analyses is illustrated with an example. An appendix outlines an extension of the methodology to ordinal endpoints.

We investigated whether karyotype analysis and mutational screening by next generation sequencing could predict outcome in 101 newly diagnosed chronic lymphocytic leukemia patients with high-risk features, as defined by the presence of unmutated IGHV gene and/or 11q22/17p13 deletion by FISH and/or TP53 mutations. Cytogenetic analysis showed favorable findings (normal karyotype and isolated 13q14 deletion) in 30 patients, unfavorable (complex karyotype and/or 17p13/11q22 deletion) in 34 cases and intermediate (all other abnormalities) in 36 cases. A complex karyotype was present in 21 patients. Mutations were detected in 56 cases and were associated with unmutated IGHV status (p = 0.040) and complex karyotype (p = 0.047). TP53 disruption (i.e. TP53 mutations and/or 17p13 deletion by FISH) correlated with the presence of ≥ 2 mutations (p = 0.001) and a complex karyotype (p = 0.012). By multivariate analysis, an advanced Binet stage (p < 0.001) and an unfavorable karyotype (p = 0.001) predicted a shorter time to first treatment. TP53 disruption (p = 0.019) and the unfavorable karyotype (p = 0.028) predicted a worse overall survival. A shorter time to chemorefractoriness was associated with TP53 disruption (p = 0.001) and unfavorable karyotype (p = 0.025). Patients with both unfavorable karyotype and TP53 disruption presented a dismal outcome (median overall survival and time to chemorefractoriness of 28.7 and 15.0 months, respectively). In conclusion, karyotype analysis refines risk stratification in high-risk CLL patients and could identify a subset of patients with highly unfavorable outcome requiring alternative treatments.

Patients with low National Institutes of Health Stroke Scale (NIHSS) scores are frequently excluded from thrombolysis, but more than 25% of them remain disabled. We sought to define a validated minor stroke definition to reduce the inappropriate treatment exclusion. From an outcome database, untreated patients with an NIHSS score of 5 or less presenting within a 4.5-hour window were identified and 3-month modified Rankin Scale (mRS) outcomes were analyzed according to individual isolated symptoms and total NIHSS scores. The validity of the following minor stroke definitions were assessed: (1) the National Institute of Neurological Disorders and Stroke Tissue Plasminogen Activator (NINDS-TPA) trials' definition, (2) the total NIHSS score, varying a cutoff point from 0 to 4, and (3) our proposed definition that included an NIHSS score = 0 or an NIHSS score = 1 on the items of level of consciousness (LOC), gaze, facial palsy, sensory, or dysarthria. Of 647 patients, 172 patients (26.6%) had a 3-month unfavorable outcome (mRS score 2-6). Favorable outcome was achieved in more than 80% of patients with an NIHSS score of 1 or less or with an isolated symptom on the LOC, gaze, facial palsy, sensory, or dysarthria item. In contrast, unfavorable outcome proportion was more than 25% in patients with an NIHSS score of 2 or more. When the NINDS-TPA trials' definition, our definition, or the definition of an NIHSS score of 1 or less were applied, more than 75% of patients with an unfavorable outcome were defined as a non-minor stroke and less than 15% of patients with an unfavorable outcome were defined as a minor stroke. Implementation of an optimal definition of minor stroke into thrombolysis decision-making process would decrease the unfavorable outcomes in patients with low NIHSS scores.

After severe traumatic brain injury (sTBI) associated with uncontrollable high intracranial pressure (ICP), today the main challenge for neurosurgeons remains to identify who may obtain benefit from decompressive craniectomy (DC) and which factors after DC influence the prognosis of these patients. The aim of this paper was to identify the pre- and postoperative determinants of outcome after DC. This retrospective study included all patients undergoing DC for sTBI from 2003 to 2011. The 6-month outcome, assessed using the Glasgow Outcome Scale (GOS), was dichotomized into favorable (GOS scores 4 and 5) and unfavorable (GOS scores 1-3) outcome. Predictors of outcome were identified by uni- and multivariate analysis. There were 190 patients who underwent DC for sTBI in this study. Sixty patients (31.6%) died within 30 days after DC. Independent prognostic factors for survival after 30 days were Glasgow Coma Scale score at admission greater than 5 (P = 0.002) and bilateral pupil reactivity (P < 0.0001). Thirty days after DC, 67 patients (51.5%) out of 130 had unfavorable outcome (GOS scores 1-3) and 63 patients (49.5%) presented favorable outcome (GOS scores 4 and 5). The independent preoperative prognostic factors for poor outcome were age over 65 years (P < 0.0001) and bilateral absence of pupil reactivity (P = 0.0165). After DC, onset of postoperative hydrocephalus and delayed cranioplasty (3 months after DC) was associated with unfavorable outcome at multivariate analysis (P = 0.002 and P < 0.0001, respectively). In our study, the development of hydrocephalus after DC for sTBI and delayed cranial reconstruction were associated with unfavorable outcome. Copyright © 2018 Elsevier Inc. All rights reserved.

The accurate prediction of outcome after out-of-hospital cardiac arrest (OHCA) is of major importance. The recently described Full Outline of UnResponsiveness (FOUR) is well adapted to mechanically ventilated patients and does not depend on verbal response. To evaluate the ability of FOUR assessed by intensivists to accurately predict outcome in OHCA. We prospectively identified patients admitted for OHCA with a Glasgow Coma Scale below 8. Neurological assessment was performed daily. Outcome was evaluated at 6 months using Glasgow-Pittsburgh Cerebral Performance Categories (GP-CPC). Eighty-five patients were included. At 6 months, 19 patients (22%) had a favorable outcome, GP-CPC 1-2, and 66 (78%) had an unfavorable outcome, GP-CPC 3-5. Compared to both brainstem responses at day 3 and evolution of Glasgow Coma Scale, evolution of FOUR score over the three first days was able to predict unfavorable outcome more precisely. Thus, absence of improvement or worsening from day 1 to day 3 of FOUR had 0.88 (0.79-0.97) specificity, 0.71 (0.66-0.76) sensitivity, 0.94 (0.84-1.00) PPV and 0.54 (0.49-0.59) NPV to predict unfavorable outcome. Similarly, the brainstem response of FOUR score at 0 evaluated at day 3 had 0.94 (0.89-0.99) specificity, 0.60 (0.50-0.70) sensitivity, 0.96 (0.92-1.00) PPV and 0.47 (0.37-0.57) NPV to predict unfavorable outcome. The absence of improvement or worsening from day 1 to day 3 of FOUR evaluated by intensivists provides an accurate prognosis of poor neurological outcome in OHCA.

Severe traumatic brain injury (TBI) is characterized mainly by diffuse axonal injuries (DAI). The cortico-subcortical disconnections induced by such fiber disruption play a central role in consciousness recovery. We hypothesized that these cortico-subcortical deafferentations inferred from diffusion MRI data could differentiate between TBI patients with favorable or unfavorable (death, vegetative state, or minimally conscious state) outcome one year after injury. Cortico-subcortical fiber density maps were derived by using probabilistic tractography from diffusion tensor imaging data acquired in 24 severe TBI patients and 9 healthy controls. These maps were compared between patients and controls as well as between patients with favorable (FO) and unfavorable (UFO) 1-year outcome to identify the thalamo-cortical and ponto-thalamo-cortical pathways involved in the maintenance of consciousness. Thalamo-cortical and ponto-thalamo-cortical fiber density was significantly lower in TBI patients than in healthy controls. Comparing FO and UFO TBI patients showed thalamo-cortical deafferentation associated with unfavorable outcome for projections from ventral posterior and intermediate thalamic nuclei to the associative frontal, sensorimotor and associative temporal cortices. Specific ponto-thalamic deafferentation in projections from the upper dorsal pons (including the reticular formation) was also associated with unfavorable outcome. Fiber density of cortico-subcortical pathways as measured from diffusion MRI tractography is a relevant candidate biomarker for early prediction of one-year favorable outcome in severe TBI.

Are women with polycystic ovary syndrome at increased cardiovascular disease risk later in life?

PubMed

Gunning, M N; Fauser, B C J M

2017-06-01

To date, the world's leading cause of death amongst women is cardiovascular disease. Polycystic ovary syndrome (PCOS) is associated with an unfavorable cardiometabolic profile in early life. Apart from dyslipidemia, obesity and onset of type 2 diabetes mellitus, androgens are thought to influence cardiovascular health. The question rises whether women with PCOS are truly at risk for cardiovascular disease in later life. In this review paper, we aim to reflect on this assumed relation based on studies in different stages of life in women with PCOS. Cardiovascular risk factors (type 2 diabetes mellitus, obesity and metabolic syndrome), surrogate outcomes (flow-mediated dilation, carotid intima-media thickness and coronary artery calcium) and clinical long-term outcomes (cardiovascular disease and mortality) will be summarized. Data on cardiovascular disease and mortality in peri- and postmenopausal women with PCOS appear to be controversial. Whether androgens have a protective or unfavorable influence on the manifestation of cardiovascular disease remains uncertain. The need for large, prospective, well-phenotyped cohort studies of women with PCOS is high. Only then will we be able to answer this research question.

To evaluate the long-term clinical and radiographic outcomes of open and close treatment of condylar fractures of mandible in children. A total of 78 cases (105 mandibular condylar fractures) were included in this study. All patients (younger than 12 years at the time of injury were followed up for at least 3 years. According to the classification of the condylar fractures, open or close treatment was chosen. Clinical outcomes were classified as favorable or unfavorable depending on the mouth opening, pattern of mouth opening, occlusion, facial symmetry. Condylar remodeling was defined as complete, moderate, or poor based on the radiographic findings. Depending on the classification, 14 sides of type I, 48 sides of type II and 43 sides of type III were included in this study. Open treatment was chosen in 51 sides and close treatment was chosen in 54 sides. Most of the patients acquired satisfactory clinical outcomes. Better radiologic remodeling of the condylar process was found in the patients treated by open treatment. Favorable long-term clinical outcomes were obtained in both open and close treatment of mandibular condylar fractures. A better morphological remodeling of condylar process was found in patients with open treatment.

Microdialysis Monitoring of CSF Parameters in Severe Traumatic Brain Injury Patients: A Novel Approach

PubMed Central

Thelin, Eric P.; Nelson, David W.; Ghatan, Per Hamid; Bellander, Bo-Michael

2014-01-01

Background: Neuro-intensive care following traumatic brain injury (TBI) is focused on preventing secondary insults that may lead to irreversible brain damage. Microdialysis (MD) is used to detect deranged cerebral metabolism. The clinical usefulness of the MD is dependent on the regional localization of the MD catheter. The aim of this study was to analyze a new method of continuous cerebrospinal fluid (CSF) monitoring using the MD technique. The method was validated using conventional laboratory analysis of CSF samples. MD-CSF and regional MD-Brain samples were correlated to patient outcome. Materials and Methods: A total of 14 patients suffering from severe TBI were analyzed. They were monitored using (1) a MD catheter (CMA64-iView, n = 7448 MD samples) located in a CSF-pump connected to the ventricular drain and (2) an intraparenchymal MD catheter (CMA70, n = 8358 MD samples). CSF-lactate and CSF-glucose levels were monitored and were compared to MD-CSF samples. MD-CSF and MD-Brain parameters were correlated to favorable (Glasgow Outcome Score extended, GOSe 6–8) and unfavorable (GOSe 1–5) outcome. Results: Levels of glucose and lactate acquired with the CSF-MD technique could be correlated to conventional levels. The median MD recovery using the CMA64 catheter in CSF was 0.98 and 0.97 for glucose and lactate, respectively. Median MD-CSF (CMA 64) lactate (p = 0.0057) and pyruvate (p = 0.0011) levels were significantly lower in the favorable outcome group compared to the unfavorable group. No significant difference in outcome was found using the lactate:pyruvate ratio (LPR), or any of the regional MD-Brain monitoring in our analyzed cohort. Conclusion: This new technique of global MD-CSF monitoring correlates with conventional CSF levels of glucose and lactate, and the MD recovery is higher than previously described. Increase in lactate and pyruvate, without any effect on the LPR, correlates to unfavorable outcome, perhaps related to the presence of erythrocytes in the CSF. PMID:25228896

Treatment of Early-Stage Unfavorable Hodgkin Lymphoma: Efficacy and Toxicity of 4 Versus 6 Cycles of ABVD Chemotherapy With Radiation

Gunther, Jillian R.; Fanale, Michelle A.; Reddy, Jay P.

Purpose: The German Hodgkin Study Group HD11 trial validated 4 cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy followed by involved field radiation therapy (IFRT) for early unfavorable Hodgkin lymphoma (HL) patients. However, practitioners often recommend 6 cycles followed by RT, especially for bulky disease. We compared patient outcomes after treatment with 4 or 6 cycles of ABVD followed by RT (IFRT and involved site RT [ISRT]). Methods and Materials: We identified 128 patients treated for early unfavorable HL (GHSG criteria) between 2000 and 2013. Clinical outcomes (overall survival [OS] and freedom from relapse [FFR]) were estimated using Kaplan-Meier analysis. Toxicitiesmore » were evaluated. Results: The median follow-up time was 5.0 years. Patients received 4 (70 patients, 55%) or 6 (58 patients, 45%) cycles of chemotherapy. Bulky disease was present in 22 patients (31%; 0 stage IA, 3 stage IB, 19 stage IIA) of the 4-cycle group and 42 patients (72%; 5 stage IA, 3 stage IB, 34 stage IIA) of the 6-cycle group. For patients receiving 4 and 6 cycles, the 6-year OS was 100% and 97% (P=.35), respectively, and the 6 year FFR was 100% and 98% (P=.28), respectively. More patients received 6 cycles if they were treated before 2010 (HD11 report) (P=.01) and if they had bulky disease (P<.01). Sixty-eight percent of patients received ISRT. The 6-year FFR was 99% and 100% for patients receiving ISRT and IFRT, respectively (P=.58). More patients experienced bleomycin pulmonary toxicity in the 6-cycle group (20% vs 31%, P=.16). For patients with bulky disease, the 4-year FFR was similar with receipt of 4 (100%) or 6 (98%) cycles (P=.48) and IFRT (100%) or ISRT (98%) (P=.52). There were no deaths among patients with bulky disease. Conclusions: Patients with early unfavorable HL have excellent outcomes with 4 cycles of ABVD chemotherapy followed by ISRT. Six cycles of chemotherapy does not appear superior for disease control, even for bulky disease.« less

There were no deaths among patients with bulky disease. Patients with early unfavorable HL have excellent outcomes with 4 cycles of ABVD chemotherapy followed by ISRT. Six cycles of chemotherapy does not appear superior for disease control, even for bulky disease. Copyright © 2016 Elsevier Inc. All rights reserved.

We have used a medical database to analyze our activity since 2005. We observed a frequent association between bone and joint infection (BI) and bacteremia. Our aim was to characterize patients with BI and bacteremia, and focus on the outcome. Our database includes the prospective recording of 28 characteristics of all hospitalized patients, including diagnosis, comorbid conditions, microbiological data, therapy, and outcome. We selected patients presenting with BI in this database, from July 2005 to December 2012. Fever before blood culture was retrospectively documented from the patient's chart. Chronic BI was defined as a disease lasting more than 1 month. An unfavorable outcome was defined by the need for intensive care or death. Six hundred and thirty-two patients presented with BI and 125 with bacteremia (19.8%). We used a stepwise logistic regression analysis and determined that bacteremia was associated with vertebral osteomyelitis, OR, 3.97, P<0.001; alcohol abuse, OR, 2.51, P=0.010; fever, OR, 2.43, P<0.001; neurological and/or psychiatric diseases, OR, 2.41, P ≤ 0.001; and Staphylococcus aureus infection, OR, 2.32, P<0.001. The outcome was unfavorable in 23 cases (3.6%), associated with bacteremia, OR, 8.00, P<0.001, age> 60 years, OR, 4.78, P=0.018, and S. aureus infection, OR, 3.96, P=0.010. No single comorbid condition was significantly associated with an unfavorable outcome. Bacteremia occurred in nearly 20% of the patients presenting with BI, and was associated with identifiable comorbid conditions; it was the main risk factor for an unfavorable outcome.

Resuscitation of patients presenting with hemorrhagic shock after major trauma has evolved to incorporate multiple strategies to maintain tissue perfusion and oxygenation while managing coagulation disorders. We aimed to study changes across time in long-term outcomes in patients with major trauma. A retrospective observational study in a single major trauma center in Australia was conducted. We included all patients with major trauma and massive blood transfusion within the first 24 h during a 6-year period (from 2006 to 2011). The main outcome measures were Glasgow Outcome Score-Extended (GOSE) and work capacity at 6 and 12 months. There were 5,915 patients with major trauma of which 365 (6.2%; 95% confidence interval [95% CI], 5.6 - 6.8) received a massive transfusion. The proportion of major trauma patients receiving a massive transfusion decreased across time from 8.2% to 4.4% (P < 0.01). There were statistically significant trends toward lower volumes of red blood cell transfusion and higher ratios of fresh-frozen plasma to red blood cells (P < 0.01). Among massively transfused patients, there was no significant change in measured outcomes during the study period, with a persistent 23% mortality in hospital, 52% unfavorable GOSE at 6 months, and 44% unfavorable GOSE at 12 months. Massive transfusion was independently associated with unfavorable outcomes at 6 months after injury (adjusted odds ratio, 1.56; 95% CI, 1.05 - 2.31) but not at 12 months (adjusted odds ratio, 0.85; 95% CI, 0.72 - 1.01). A significant reduction in massive transfusion rates was observed. Unfavorable long-term outcomes among patients receiving a massive transfusion after trauma were frequent with a substantial proportion of survivors experiencing poor functional status 1 year after injury.

The Association of Unfavorable Outcomes with the Intensity of Neurosurgical Care in the United States

PubMed Central

2014-01-01

Object There is wide regional variability in the volume of procedures performed for similar surgical patients throughout the United States. We investigated the association of the intensity of neurosurgical care (defined as the average annual number of neurosurgical procedures per capita) with mortality, length of stay (LOS), and rate of unfavorable discharge for inpatients after neurosurgical procedures. Methods We performed a retrospective cohort study involving the 202,518 patients who underwent cranial neurosurgical procedures from 2005–2010 and were registered in the National Inpatient Sample (NIS) database. Regression techniques were used to investigate the association of the average intensity of neurosurgical care with the average mortality, LOS, and rate of unfavorable discharge. Results The inpatient neurosurgical mortality, rate of unfavorable discharge, and average LOS varied significantly among several states. In a multivariate analysis male gender, coverage by Medicaid, and minority racial status were associated with increased mortality, rate of unfavorable discharge, and LOS. The opposite was true for coverage by private insurance, higher income, fewer comorbidities and small hospital size. There was no correlation of the intensity of neurosurgical care with the mortality (Pearson's ρ = −0.18, P = 0.29), rate of unfavorable discharge (Pearson's ρ = 0.08, P = 0.62), and LOS of cranial neurosurgical procedures (Pearson's ρ = −0.21, P = 0.22). Conclusions We observed significant disparities in mortality, LOS, and rate of unfavorable discharge for cranial neurosurgical procedures in the United States. Increased intensity of neurosurgical care was not associated with improved outcomes. PMID:24647225

Secondary generalization of focal-onset seizures: examining the relationship between seizure propagation and epilepsy surgery outcome.

Surgical intervention often fails to achieve seizure-free results in patients with intractable epilepsy. Identifying features of the epileptic brain that dispose certain patients to unfavorable outcomes is critical for improving surgical candidacy assessments. Recent research by Martinet, Ahmad, Lepage, Cash, and Kramer ( J Neurosci 35: 9477-9490, 2015) suggests that pathways of secondary seizure generalization distinguish patients with favorable (i.e., seizure free) vs. unfavorable (i.e., seizure persistent) surgical outcomes, lending insights into the network mechanisms of epilepsy surgery failure.

Higher plasma 8-iso-Prostaglandin F2α concentrations have been associated with poor outcome of severe traumatic brain injury. We further investigated the relationships between plasma 8-iso-Prostaglandin F2α concentrations and clinical outcomes in patients with acute intracerebral hemorrhage. Plasma 8-iso-Prostaglandin F2α concentrations of 128 consecutive patients and 128 sex- and gender-matched healthy subjects were measured by enzyme-linked immunosorbent assay. We assessed their relationships with disease severity and clinical outcomes including 1-week mortality, 6-month mortality and unfavorable outcome (modified Rankin Scale score>2). Plasma 8-iso-Prostaglandin F2α concentrations were substantially higher in patients than in healthy controls. Plasma 8-iso-Prostaglandin F2α concentrations were positively associated with National Institutes of Health Stroke Scale (NIHSS) scores and hematoma volume using a multivariate linear regression. It emerged as an independent predictor for clinical outcomes of patients using a forward stepwise logistic regression. ROC curves identified the predictive values of plasma 8-iso-Prostaglandin F2α concentrations, and found its predictive value was similar to NIHSS scores and hematoma volumes. However, it just numerically added the predictive values of NIHSS score and hematoma volume. Increased plasma 8-iso-Prostaglandin F2α concentrations are associated with disease severity and clinical outcome after acute intracerebral hemorrhage. Copyright © 2014 Elsevier B.V.

Objective To determine if early serum S100B and neuron-specific enolase (NSE) levels are associated with neuroradiographic and clinical evidence of brain injury in newborns with encephalopathy. Study design Patients who received therapeutic whole-body hypothermia were prospectively enrolled in this observational study. Serum specimens were collected at 0, 12, 24, and 72 hours of cooling. S100B and NSE levels were measured by enzyme linked immunosorbent assay. Magnetic resonance imaging was performed in surviving infants at 7–10 days of life. Standardized neurologic examination was performed by a child neurologist at 14 days of life. Multiple linear regression analyses were performed to evaluate the association between S100B and NSE levels and unfavorable outcome (death or severe magnetic resonance imaging injury/significant neurologic deficit). Cutoff values were determined by receiver operating curve analysis. Results Newborns with moderate to severe encephalopathy were enrolled (n = 75). Median pH at presentation was 6.9 (range, 6.5–7.35), and median Apgar scores of 1 at 1 minute, 3 at 5 minutes, and 5 at 10 minutes. NSE and S100B levels were higher in patients with unfavorable outcomes across all time points. These results remained statistically significant after controlling for covariables, including encephalopathy grade at presentation, Apgar score at 5 minutes of life, initial pH, and clinical seizures. Conclusion Elevated serum S100B and NSE levels measured during hypothermia were associated with neuroradiographic and clinical evidence of brain injury in encephalopathic newborns. These brain-specific proteins may be useful immediate biomarkers of cerebral injury severity. PMID:22494878

A 2-year-old female Border collie was examined for dermatitis with a partial alopecic zone around her left front member. Six months later the lesion became swollen, alopecic with ulcerated areas. Microscopy analysis of samples showed numerous non-septate, branching, thin-walled and irregular shaped hyphal elements. Fungal cultures and molecular studies identified Saksenaea vasiformis. Treatments with griseofulvin, itraconazole and surgical debridement were used, however, fourteen months later the dog was euthanatized because of the unfavorable clinical outcome.

Endocarditis may precede or complicate bacterial meningitis, but the incidence and impact of endocarditis in bacterial meningitis are unknown. We assessed the incidence and clinical characteristics of patients with meningitis and endocarditis from a nationwide cohort study of adults with community-acquired bacterial meningitis in the Netherlands from 2006 to 2012. Endocarditis was identified in 24 of 1025 episodes (2%) of bacterial meningitis. Cultures yielded Streptococcus pneumoniae in 13 patients, Staphylococcus aureus in 8 patients, and Streptococcus agalactiae, Streptococcus pyogenes, and Streptococcus salivarius in 1 patient each. Clues leading to the diagnosis of endocarditis were cardiac murmurs, persistent or recurrent fever, a history of heart valve disease, and S aureus as the causative pathogen of bacterial meningitis. Treatment consisted of prolonged antibiotic therapy in all patients and surgical valve replacement in 10 patients (42%). Two patients were treated with oral anticoagulants, and both developed life-threatening intracerebral hemorrhage. Systemic (70%) and neurological (54%) complications occurred frequently, leading to a high proportion of patients with unfavorable outcome (63%). Seven of 24 patients (29%) with meningitis and endocarditis died. Endocarditis is an uncommon coexisting condition in bacterial meningitis but is associated with a high rate of unfavorable outcome.

To study the incidence, clinical presentation, causative bacteria, and outcome of community-acquired bacterial meningitis in adults with cancer. We evaluated incidence and characteristics of patients with cancer included in a nationwide prospective cohort study of adults with community-acquired meningitis performed in the Netherlands from March 1, 2006, to September 31, 2014. All patients underwent a neurologic examination at hospital discharge, and outcome was graded using the Glasgow Outcome Scale. Active cancer was identified in 68 of 1,351 episodes (5%) and a history of cancer in 87 (6%). The annual incidence of community-acquired bacterial meningitis was 2.71-fold (95% confidence interval [CI] 1.68-4.36, p < 0.001) increased for patients with cancer compared to patients without cancer in 2010, and 3.52-fold (95% CI 2.16-5.73, p < 0.001) in 2013. The clinical presentation of bacterial meningitis in patients with cancer compared to patients without cancer was similar. Patients with active cancer presented with lower leukocyte count in blood (12.1 × 10(9) cells/L vs 17.3 × 10(9) cells/L, p < 0.001) and CSF (670 cells/mm(3) vs 2,567 cells/mm(3), p < 0.001) and were more likely to be infected with Listeria monocytogenes (21% vs 5%, p < 0.001) than patients without cancer. Active cancer was identified as an independent risk factor for unfavorable outcome in bacterial meningitis (odds ratio 1.85, 95% CI 1.09-3.13). One of 8 patients with community-bacterial meningitis was identified to have a history of cancer and cancer was considered active in half of these patients. Patients with active cancer present with lower CSF leukocyte counts, are more likely to be infected with L monocytogenes, and are at high risk of unfavorable outcome. © 2016 American Academy of Neurology.

Pediatric multidrug-resistant tuberculosis (MDR-TB) is complicated by difficult diagnosis, complex treatment, and high mortality. In South Africa, these challenges are amplified by human immunodeficiency virus (HIV) co-infection; however, evidence on treatment outcomes among co-infected children is limited. Using conventional and new pediatric definitions, to describe treatment outcomes and identify risk factors for unfavorable outcome and mortality in children aged <15 years with MDR-TB or extensively drug-resistant TB (XDR-TB) in KwaZulu-Natal, South Africa. Retrospective cohort study in a regional TB referral hospital. From January 2009 to June 2010, 84 children (median age 8 years, IQR 4-12) with MDR-TB (n = 78) or XDR-TB (n = 6) initiated treatment. Sixty-four (77%) were HIV-positive and 62 (97%) received antiretroviral therapy. Sixty-six (79%) achieved favorable treatment outcomes. Overall mortality was 11% (n = 9) at 18 months after initiation of treatment. Malnutrition (aOR 27.4, 95%CI 2.7-278.7) and severe radiographic findings (aOR 4.68, 95%CI 1.01-21.9) were associated with unfavorable outcome. New pediatric outcome definitions increased the proportion classified as cured. It is possible to successfully treat pediatric MDR-TB-HIV even in resource-poor settings. Malnutrition is a marker for severe TB-HIV disease, and is a potential target for future interventions in these patients.

The aim of this prospective study was to assess the esthetic outcome and alterations of peri-implant soft tissue using tissue-level implants. Furthermore, the influencing factors, including grafting and gingival biotype, of esthetic outcome of peri-implant soft tissue were also evaluated. Of 38 patients with single missing anterior tooth in maxilla were treated with a Straumann (®) Standard Plus SLA implant. Bone augmentation was performed in 24 patients. Follow-up was conducted at 12 and 24 months after definitive crowns placement. Esthetic outcome using the pink esthetic score/white esthetic score (PES/WES) and clinical parameters were evaluated. The mean PES/WES value at baseline, 1-year, and 2-year examination was 13.79, 14.87, and 14.96. Significant improvement was found between baseline and 1-year examination (P < 0.01). And the improvement between 1-year and 2-year examination was not significant (P = 0.40). The mean PES changing value in patients with thick biotype was significantly higher than those with thin biotype at 2-year after definitive crowns placement (P = 0.03). Graft procedure had an unfavorable effect on mean PES value both at baseline and at follow-up (P < 0.01). No implants were lost at 2-year examination. Three patients experienced peri-implant infection. No significant difference was found with the passage of time in modified plaque index (mPI), probing pocket depth (PPD), and modified bleeding index (mBI). According to the present prospective clinical study, it can be concluded that it is feasible to use tissue-level implant to support single crowns in esthetic area. Favorable short-term esthetic outcome and stability of soft tissue around single implant crowns can be expected in patients with or without graft. However, graft procedures might have an unfavorable effect on the esthetic outcome. Gingival biotype can be considered as prognostic factor for esthetic outcome. RCTs with long-term follow-up are needed to provide evidence for the long-term stability of peri-implant soft tissue using tissue-level implant systems. © 2014 John Wiley & Sons A/S.

The disease progression of eosinophilic esophagitis (EoE) from childhood into adulthood is unclear. To determine the clinical outcome of patients who were diagnosed with EoE as children, and who now are young adults. Children (<18 years old) diagnosed with EoE were enrolled in a prospective registry on demographics, presenting symptoms, and endoscopic/histologic findings. Subjects who now are adults (≥18 years old) were identified, and a structured telephone interview was conducted to obtain follow-up data on symptom prevalence (dysphagia to solids and liquids, nausea/vomiting, abdominal pain, and heartburn/regurgitation), food impaction, medication usage, health-care utilization, and resolution of atopy/food allergies. A favorable outcome was defined if EoE symptoms were resolved or improved by subjects' assessment. Unfavorable outcomes was defined as symptoms same or worse. Clinical variables that predicted a favorable outcome as an adult were examined. Mayo Dysphagia Scale (MDQ-30: scored 0-100) was administered to validate the outcome assessment. Mantel-Haenszel odds ratio and unpaired t-test were used. Fifty-eight subjects (64% male) who met study criteria were enrolled. Mean age at diagnosis was 12 years (range 4-17) and mean duration of follow-up was 8.3 years (2-16). As children, the most common presenting symptoms were abdominal pain (54%), dysphagia (33%), and vomiting (24%). As young adults, 47 subjects (81%) had a favorable outcome. Total MDQ-30 scores were 4.6 (0-30) and 14.1 (0-50) in subjects with favorable outcome and unfavorable outcome, respectively (P = 0.015). Two-thirds of subjects did not use steroids or proton pump inhibitors in the preceeding 12 months. Male children with EoE were four times more likely to have a favorable outcome as young adults compared with female children. Females were more likely to report nausea/vomiting as young adults (odds ratio 3.23, CI 0.97-10.60). Of all presenting symptoms in EoE children, dysphagia was the most likely to persist into adulthood (odds ratio 6.29, CI 1.85-21.38). Eighty one percent of EoE children had a favorable outcome as young adults. Most patients with symptom resolution did not require any form of steroid therapy or seek healthcare. © 2016 International Society for Diseases of the Esophagus.

Brain injury is the leading cause of morbidity and death following pediatric cardiac arrest. Serum biomarkers of brain injury may assist in outcome prognostication. The objectives of this study were to evaluate the properties of serum ubiquitin carboxyl-terminal esterase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP) to classify outcome in pediatric cardiac arrest. Single center prospective study. Serum biomarkers were measured at 2 time points during the initial 72 h in children after cardiac arrest (n=19) and once in healthy children (controls, n=43). We recorded demographics and details of the cardiac arrest and resuscitation. We determined the associations between serum biomarker concentrations and Pediatric Cerebral Performance Category (PCPC) at 6 months (favorable (PCPC 1-3) or unfavorable (PCPC 4-6)). The initial assessment (time point 1) occurred at a median (IQR) of 10.5 (5.5-17.0)h and the second assessment (time point 2) at 59.0 (54.5-65.0)h post-cardiac arrest. Serum UCH-L1 was higher among children following cardiac arrest than among controls at both time points (p<0.05). Serum GFAP in subjects with unfavorable outcome was higher at time point 2 than in controls (p<0.05). Serum UCH-L1 at time point 1 (AUC 0.782) and both UCH-L1 and GFAP at time point 2 had good classification accuracy for outcome (AUC 0.822 and 0.796), p<0.05 for all. Preliminary data suggest that serum UCH-L1 and GFAP may be of use to prognosticate outcome after pediatric cardiac arrest at clinically-relevant time points and should be validated prospectively.

Endovascular intervention by Flow Diverter (FD) - a densely woven stent - occludes an aneurysm by inducing thrombosis in the aneurysm sac and reconstructing the vessel. Hemodynamics plays a vital role in the thrombotic occlusion of aneurysms and eventual treatment outcome. CFD analysis of pre- and post-treatment aneurysms not only provides insight of flow modifications by FD, but also allows investigation of interventional strategies and prediction of their outcome. In this study 80 patient-specific aneurysms treated with FDs were retrospectively studied to evaluate the effect of intervention. Out of these cases, 16 required retreatment and thus are considered as having unfavorable outcome. Clinical FD deployment in these cases was simulated using an efficient virtual stenting workflow. CFD analysis was carried out on both pre- and post-treatment cases, and changes in hemodynamic parameters were calculated. Support vector machine algorithm was used to correlate the hemodynamic changes with outcome. Results show that cases having higher flow reduction into the aneurysmal sac have a better likelihood of occlusion. This suggests that changes in hemodynamics can be potentially used to predict the outcome of different clinical intervention strategies in aneurysms.

Despite theoretical postulations that individuals' conformity to masculine norms is differentially related to mental health-related outcomes depending on a variety of contexts, there has not been any systematic synthesis of the empirical research on this topic. Therefore, the authors of this study conducted meta-analyses of the relationships between conformity to masculine norms (as measured by the Conformity to Masculine Norms Inventory-94 and other versions of this scale) and mental health-related outcomes using 78 samples and 19,453 participants. Conformity to masculine norms was modestly and unfavorably associated with mental health as well as moderately and unfavorably related to psychological help seeking. The authors also identified several moderation effects. Conformity to masculine norms was more strongly correlated with negative social functioning than with psychological indicators of negative mental health. Conformity to the specific masculine norms of self-reliance, power over women, and playboy were unfavorably, robustly, and consistently related to mental health-related outcomes, whereas conformity to the masculine norm of primacy of work was not significantly related to any mental health-related outcome. These findings highlight the need for researchers to disaggregate the generic construct of conformity to masculine norms and to focus instead on specific dimensions of masculine norms and their differential associations with other outcomes.

Stroke-associated infections occur frequently and are associated with unfavorable outcome. Previous cohort studies suggest a protective effect of beta-blockers (BBs) against infections. A sympathetic drive may increase immune suppression and infections. This study is aimed at investigating the association between BB treatment at baseline and post-stroke infection in the Preventive Antibiotics in Stroke Study (PASS), a prospective clinical trial. We performed an exploratory analysis in PASS, 2,538 patients with acute phase of stroke (24 h after onset) were randomized to ceftriaxone (intravenous, 2 g per day for 4 days) in addition to stroke unit care, or standard stroke unit care without preventive antibiotic treatment. All clinical data, including use of BBs, was prospectively collected. Infection was diagnosed by the treating physician, and independently by an expert panel blinded for all other data. Multivariable analysis was performed to investigate the relation between BB treatment and infection rate. Infection, as defined by the physician, occurred in 348 of 2,538 patients (14%). Multivariable analysis showed that the use of BBs at baseline was associated with the development of infection during clinical course (adjusted OR (aOR) 1.61, 95% CI 1.19-2.18; p < 0.01). BB use at baseline was also associated with the development of pneumonia (aOR 1.56, 95% CI 1.05-2.30; p = 0.03). Baseline BB use was not associated with mortality (aOR 1.14, 95% CI 0.84-1.53; p = 0.41) or unfavorable outcome at 3 months (aOR 1.10, 95% CI 0.89-1.35; p = 0.39). Patients treated with BBs prior to stroke have a higher rate of infection and pneumonia. © 2016 S. Karger AG, Basel.

Hyperglycemia in bacterial meningitis: a prospective cohort study

PubMed Central

2009-01-01

Background Hyperglycemia has been associated with unfavorable outcome in several disorders, but few data are available in bacterial meningitis. We assessed the incidence and significance of hyperglycemia in adults with bacterial meningitis. Methods We collected data prospectively between October 1998 and April 2002, on 696 episodes of community-acquired bacterial meningitis, confirmed by culture of CSF in patients >16 years. Patients were dichotomized according to blood glucose level on admission. A cutoff random non-fasting blood glucose level of 7.8 mmol/L (140 mg/dL) was used to define hyperglycemia, and a cutoff random non-fasting blood glucose level of 11.1 mmol/L (200 mg/dL) was used to define severe hyperglycemia. Unfavorable outcome was defined on the Glasgow outcome scale as a score <5. We also evaluated characteristics of patients with a preadmission diagnosis of diabetes mellitus. Results 69% of patients were hyperglycemic and 25% severely hyperglycemic on admission. Compared with non-hyperglycemic patients, hyperglycemia was related with advanced age (median, 55 yrs vs. 44 yrs, P < 0.0001), preadmission diagnosis of diabetes (9% vs. 3%, P = 0.005), and distant focus of infection (37% vs. 28%, P = 0.02). They were more often admitted in coma (16% vs. 8%; P = 0.004) and with pneumococcal meningitis (55% vs. 42%, P = 0.007). These differences remained significant after exclusion of patients with known diabetes. Hyperglycemia was related with unfavorable outcome in a univariate analysis but this relation did not remain robust in a multivariate analysis. Factors predictive for neurologic compromise were related with higher blood glucose levels, whereas factors predictive for systemic compromise were related with lower blood glucose levels. Only a minority of severely hyperglycemic patients were known diabetics (19%). The vast majority of these known diabetic patients had meningitis due to Streptococcus pneumoniae (67%) or Listeria monocytogenes (13%) and they were at high risk for unfavorable outcome (52%). Conclusion The majority of patients with bacterial meningitis have hyperglycemic blood glucose levels on admission. Hyperglycemia can be explained by a physical stress reaction, the central nervous system insult leading to disturbed blood-glucose regulation mechanisms, and preponderance of diabetics for pneumococcal meningitis. Patients with diabetes and bacterial meningitis are at high risk for unfavorable outcome. PMID:19426501

Basis for selecting optimum antibiotic regimens for secondary peritonitis.

Adequate management of severely ill patients with secondary peritonitis requires supportive therapy of organ dysfunction, source control of infection and antimicrobial therapy. Since secondary peritonitis is polymicrobial, appropriate empiric therapy requires combination therapy in order to achieve the needed coverage for both common and more unusual organisms. This article reviews etiological agents, resistance mechanisms and their prevalence, how and when to cover them and guidelines for treatment in the literature. Local surveillances are the basis for the selection of compounds in antibiotic regimens, which should be further adapted to the increasing number of patients with risk factors for resistance (clinical setting, comorbidities, previous antibiotic treatments, previous colonization, severity…). Inadequate antimicrobial regimens are strongly associated with unfavorable outcomes. Awareness of resistance epidemiology and of clinical consequences of inadequate therapy against resistant bacteria is crucial for clinicians treating secondary peritonitis, with delicate balance between optimization of empirical therapy (improving outcomes) and antimicrobial overuse (increasing resistance emergence).

There has been longstanding controversy surrounding the influence of funding source on the conduct and outcome of medical research. In 2011, a systematic review of the use of recombinant bone morphogenetic protein-2 revealed underreporting of unfavorable outcomes in some industry-sponsored trials. We hypothesize that Industrial funding and the presence of potential conflict of interest will be associated with low levels of evidence (LOE) and greater proportions of favorable outcomes in spinal research. The aim of this study is to investigate the association between funding source and potential conflict of interest on the LOE and study outcome in the current spinal research. Systematic review of all the spinal publications in five leading spinal, orthopedics, neurosurgery, and general medical journals during 2010 (print and online). Supplements were included. Outcome and the LOE of research papers. Two reviewers independently assessed all publications. Commentaries, editorials, letters, open operating theatres, case reports, narrative reviews, and study protocols were excluded. The self-reported potential conflict of interest and type of funding was extracted from each paper. Funding type was classified as foundation, industry, public, intramural, multiple (including industry), multiple (without industry), and unfunded. The outcome of each study was classified as favorable, unfavorable, equivocal, or not applicable. Clinical publications were ranked using the LOE guidelines produced by the Oxford Center for Evidence-Based Medicine. Overall, 1356 papers were analyzed, out of which 864 were suitable for LOE grading. There was good interobserver reliability for assignment of LOE grade, κ=0.897 (p<.01) and study outcome κ=0.804 (p<.01). A significant association was found between LOE and source of funding (p<.01). Industry-funded studies had the greatest proportion of level IV evidence (65%). There was a significant association between the funding source and study outcome (p=.01). The proportion of industry-funded studies with favorable outcomes (88%) was higher than that of publicly and foundation-funded studies (73% and 74%, respectively). The associated odds ratio for reporting favorable outcomes in industry-funded studies compared with studies with public and foundation funding was 2.7 (95% confidence interval [CI], 1.4-5.3), and 2.6 (95% CI, 1.3-5.2), respectively. A significant association between LOE and study outcome (p<.01) was also identified. Level I studies had the highest proportions of unfavorable (14%) and equivocal (23%) outcomes. Level IV studies had the highest proportion of favorable outcome (85%). There was no association between self-reported conflict of interest and LOE (p=.83) or study outcome (p=.25). We demonstrated a significant association between source of funding, study outcome, and LOE in spinal research. A large proportion of industry funded research was shown to provide level IV evidence and report favorable outcome. Copyright © 2014 Elsevier Inc. All rights reserved.

Low back pain (LBP) encompasses heterogeneous patients unlikely to respond to a unique treatment. Identifying sub-groups of LBP may help to improve treatment outcomes. This is a hypothesis-setting study designed to create a clinical prediction rule (CPR) that will predict favorable outcomes in soldiers with sub-acute and chronic LBP participating in a multi-station exercise program. Military members with LBP participated in a supervised program comprising 7 stations each consisting of exercises of increasing difficulty. Demographic, impairment and disability data were collected at baseline. The modified Oswestry Disability Index (ODI) was administered at baseline and following the 6-week program. An improvement of 50% in the initial ODI score was considered the reference standard to determine a favorable outcome. Univariate associations with favorable outcome were tested using chi-square or paired t-tests. Variables that showed between-group (favorable/unfavorable) differences were entered into a logistic regression after determining the sampling adequacy. Finally, continuous variables were dichotomized and the sensitivity, specificity and positive and negative likelihood ratios were determined for the model and for each variable. A sample of 85 participants was included in analyses. Five variables contributed to prediction of a favorable outcome: no pain in lying down (p = 0.017), no use of antidepressants (p = 0.061), FABQ work score < 22.5 (p = 0.061), fewer than 5 physiotherapy sessions before entering the program (p = 0.144) and less than 6 months' work restriction (p = 0.161). This model yielded a sensitivity of 0.78, specificity of 0.80, LR+ of 3.88, and LR- of 0.28. A 77.5% probability of favorable outcome can be predicted by the presence of more than three of the five variables, while an 80% probability of unfavorable outcome can be expected if only three or fewer variables are present. The use of prognostic factors may guide clinicians in identifying soldiers with LBP most likely to have a favorable outcome. Further validation studies are needed to determine if the variables identified in our study are treatment effect modifiers that can predict success following participation in the multi-station exercise program.

Some previous articles reported that antiviral treatment was effective to reduce the colectomy rate in ulcerative colitis (UC) patients with cytomegalovirus (CMV) infection. Kopylov et al recently carried out a systematic review and meta-analysis to evaluate the impact of antiviral therapy on CMV-positive UC. The results showed that patients who received antiviral treatment had a higher risk of 30-d colectomy. We found that in this meta-analysis, some studies were inappropriately included, leading to an unfavorable outcome of anti-CMV therapy in UC patients.

Purpose: To evaluate the effect of continued cigarette smoking among patients undergoing radiation therapy for head-and-neck cancer by comparing the clinical outcomes among active smokers and quitters. Methods and Materials: A review of medical records identified 101 patients with newly diagnosed squamous cell carcinoma of the head and neck who continued to smoke during radiation therapy. Each active smoker was matched to a control patient who had quit smoking before initiation of radiation therapy. Matching was based on tobacco history (pack-years), primary site, age, sex, Karnofsky Performance Status, disease stage, radiation dose, chemotherapy use, year of treatment, and whether surgicalmore » resection was performed. Outcomes were compared by use of Kaplan-Meier analysis. Normal tissue effects were graded according to the Radiation Therapy Oncology Group/European Organization for the Treatment of Cancer toxicity criteria. Results: With a median follow-up of 49 months, active smokers had significantly inferior 5-year overall survival (23% vs. 55%), locoregional control (58% vs. 69%), and disease-free survival (42% vs. 65%) compared with the former smokers who had quit before radiation therapy (p < 0.05 for all). These differences remained statistically significant when patients treated by postoperative or definitive radiation therapy were analyzed separately. The incidence of Grade 3 or greater late complications was also significantly increased among active smokers compared with former smokers (49% vs. 31%, p = 0.01). Conclusions: Tobacco smoking during radiation therapy for head-and-neck cancer is associated with unfavorable outcomes. Further studies analyzing the biologic and molecular reasons underlying these differences are planned.« less

Quality of life in purely ocular myasthenia in Japan

PubMed Central

2014-01-01

Background Since there has been no conclusive evidence regarding the treatment of ocular myasthenia, treatment guidelines were recently issued by the European Federation of Neurological Societies/European Neurological Society (EFNS/ENS). However, the therapeutic outcomes concerning the quality-of-life (QOL) of patients with ocular myasthenia are not yet fully understood. Methods We investigated the therapeutic outcomes of patients with purely ocular myasthenia in a multicenter cross-sectional survey in Japan. To evaluate the severity of ocular symptoms, we used the ocular-quantitative MG (QMG) score advocated by Myasthenia Gravis Foundation of America. We used the Japanese translated version of the MG-QOL15, a self-appraised scoring system. Results Of 607 myasthenia gravis (MG) patients with an observation-duration of illness ≥ 2 years, the cases of 123 patients (20%) were limited to ocular muscles (purely ocular myasthenia). During the entire clinical course, 81 patients experienced both ptosis and diplopia, 36 had ptosis alone, and six had diplopia alone. Acetyl-cholinesterase inhibitors and prednisolone were used in 98 and 52 patients, respectively. Treatment improved ocular symptoms, with the mean reduction in ocular-QMG score of 2.3 ± 1.8 points. However, 47 patients (38%) failed to gain minimal manifestation or a better status. Patients with unfavorable outcomes also self-reported severe QOL impairment. Multivariate analyses showed that the pretreatment ocular-QMG score was associated with unfavorable outcomes, but not associated with the patient’s QOL. Conclusion A treatment strategy designed in accord with a patient's ocular presentation must be considered in order to improve ocular symptoms and the patient's QOL. PMID:24996227

Self-verification in clinical depression: the desire for negative evaluation.

Do clinically depressed individuals seek favorable or unfavorable information about the self? Self-verification theory makes the counterintuitive prediction that depressed individuals solicit feedback that confirms their negative self-views. To test this prediction, participants were classified on the basis of a structured clinical interview and self-report measures into high-esteem, low self-esteem, and depressed groups. All participants were offered a choice between receiving favorable or unfavorable feedback; 82% of the depressed participants chose the unfavorable feedback, compared to 64% of the low self-esteem participants and 25% of the high self-esteem participants. Additional evidence indicated that depressed individuals also failed to exploit fully an opportunity to acquire favorable evaluations that were self-verifying. The authors discuss how seeking negative evaluations and failing to seek favorable evaluations may help maintain depression.

To identify predictors of unfavorable clinical and radiologic outcomes a minimum of 5 years after pullout fixation for medial meniscus posterior root tears (MMPRTs). In total, 40 patients who were followed for >5 years after pullout fixation in MMPRT were recruited. The mean follow-up duration was 71.1 months. Clinical outcomes, including Lysholm score and International Knee Documentation Committee (IKDC) score, and radiographic results, including Kellgren-Lawrence (K-L; 0/1/2/3/4) grade and medial joint space width, were evaluated preoperatively and at final follow-up. Preoperative prognostic factors, including age, sex, body mass index, degree of varus alignment, K-L grade, medial joint space width, meniscal extrusion, and cartilage status, by the modified Outerbridge classification (grades 1 or 2 v 3 or 4), for relatively unfavorable (fair or poor grade) Lysholm or IKDC score, and progression of K-L grade were investigated by multivariate logistic regression analysis. The mean Lysholm score (52.1 ± 8.8 to 83.8 ± 11.9) and IKDC score (40.1 ± 7.6 to 73.3 ± 10.9) were improved significantly (P < .001), although the loss of medial joint space width (4.8 ± 1.1 to 3.9 ± 1.1 mm) and K-L grade (6/25/9/0/0 to 0/11/20/9/0) progressed significantly (P < .001). Unfavorable prognostic factors of the Lysholm score were grade ≥3 chondral lesions (odds ratio [OR] = 5.993; P = .028) and varus mechanical alignment (OR = 1.644; P = .017), for IKDC score were grade ≥3 chondral lesions (OR = 11.146; P = .038) and older age (OR = 1.200; P = .017). Preoperative chondral lesion grade ≥3 increased the risk of K-L grade progression (OR = 11.000; P = .031). Clinically, modified Outerbridge classification grade ≥3 chondral lesions, varus alignment, and older age were found to predict a poor prognosis after MMPRT fixation. In terms of radiographic K-L grade progression, grade ≥3 chondral lesions were identified as a poor prognostic factor. Level IV, case series.

OBJECTIVE Glasgow Coma Scale (GCS) scores and pupil responses are key indicators of the severity of traumatic brain damage. The aim of this study was to determine what information would be gained by combining these indicators into a single index and to explore the merits of different ways of achieving this. METHODS Information about early GCS scores, pupil responses, late outcomes on the Glasgow Outcome Scale, and mortality were obtained at the individual patient level by reviewing data from the CRASH (Corticosteroid Randomisation After Significant Head Injury; n = 9,045) study and the IMPACT (International Mission for Prognosis and Clinical Trials in TBI; n = 6855) database. These data were combined into a pooled data set for the main analysis. Methods of combining the Glasgow Coma Scale and pupil response data varied in complexity from using a simple arithmetic score (GCS score [range 3-15] minus the number of nonreacting pupils [0, 1, or 2]), which we call the GCS-Pupils score (GCS-P; range 1-15), to treating each factor as a separate categorical variable. The content of information about patient outcome in each of these models was evaluated using Nagelkerke's R 2 . RESULTS Separately, the GCS score and pupil response were each related to outcome. Adding information about the pupil response to the GCS score increased the information yield. The performance of the simple GCS-P was similar to the performance of more complex methods of evaluating traumatic brain damage. The relationship between decreases in the GCS-P and deteriorating outcome was seen across the complete range of possible scores. The additional 2 lowest points offered by the GCS-Pupils scale (GCS-P 1 and 2) extended the information about injury severity from a mortality rate of 51% and an unfavorable outcome rate of 70% at GCS score 3 to a mortality rate of 74% and an unfavorable outcome rate of 90% at GCS-P 1. The paradoxical finding that GCS score 4 was associated with a worse outcome than GCS score 3 was not seen when using the GCS-P. CONCLUSIONS A simple arithmetic combination of the GCS score and pupillary response, the GCS-P, extends the information provided about patient outcome to an extent comparable to that obtained using more complex methods. The greater range of injury severities that are identified and the smoothness of the stepwise pattern of outcomes across the range of scores may be useful in evaluating individual patients and identifying patient subgroups. The GCS-P may be a useful platform onto which information about other key prognostic features can be added in a simple format likely to be useful in clinical practice.

Abstract Marchiafava–Bignami disease (MBD) is a rare neurological disease usually associated with chronic alcoholism and characterized by demyelination and necrosis. Our aims were to describe the clinicoradiological features and identify factors that may affect the prognosis of patients with MBD. We examined clinical manifestations, laboratory results, and neuroradiological features of 9 patients with MBD. The patients were classified into 2 subgroups (favorable and poor outcome subgroups) based on the Modified Oxford Handicap Scale (MOSH). In addition, we compared the clinical and neuroimaging features between the 2 subgroups. Nine adult male patients (age of onset range 37–62 years, with a mean age of 47.00 ± 14.50 years) were included in this study. According to MOSH, 4 patients were placed in the poor outcome subgroup (MOHS ≥ 3), 5 patients were placed in the favorable outcome subgroup (MOHS ≤ 2). Relatively high score of MAST-C (≥6) (P = .008), extracallosal lesions (P = .048), GCS (P = .026), cerebral lobe impairment (P = .048) was significantly more common in the poor outcome subgroup. Clinical manifestations of MBD are variable and lack specificity. Early diagnosis by relatively specific performance of bisymmetric lesions in corpus callosum of diffusion-weighted imaging (DWI) may affect the prognosis. The prognosis of patients with severe disturbance of consciousness, heavy alcohol consumption, extracallosal lesions, cerebral lobe impairment is probably unfavorable. PMID:29384842

Biomarkers ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP) may help detect brain injury, assess its severity, and improve outcome prediction. This study aimed to evaluate the prognostic value of these biomarkers during the first days after brain injury. Serum UCH-L1 and GFAP were measured in 324 patients with traumatic brain injury (TBI) enrolled in a prospective study. The outcome was assessed using the Glasgow Outcome Scale (GOS) or the extended version, Glasgow Outcome Scale-Extended (GOSE). Patients with full recovery had lower UCH-L1 concentrations on the second day and patients with favorable outcome had lower UCH-L1 concentrations during the first 2 days compared with patients with incomplete recovery and unfavorable outcome. Patients with full recovery and favorable outcome had significantly lower GFAP concentrations in the first 2 days than patients with incomplete recovery or unfavorable outcome. There was a strong negative correlation between outcome and UCH-L1 in the first 3 days and GFAP levels in the first 2 days. On arrival, both UCH-L1 and GFAP distinguished patients with GOS score 1-3 from patients with GOS score 4-5, but not patients with GOSE score 8 from patients with GOSE score 1-7. For UCH-L1 and GFAP to predict unfavorable outcome (GOS score ≤ 3), the area under the receiver operating characteristic curve was 0.727, and 0.723, respectively. Neither UCHL-1 nor GFAP was independently able to predict the outcome when age, worst Glasgow Coma Scale score, pupil reactivity, Injury Severity Score, and Marshall score were added into the multivariate logistic regression model. GFAP and UCH-L1 are significantly associated with outcome, but they do not add predictive power to commonly used prognostic variables in a population of patients with TBI of varying severities.

OBJECTIVE There has been increased interest in the potential importance of biochemical parameters as predictors of outcome in severe traumatic brain injury (sTBI). METHODS Of 107 patients with sTBI (age 18-65 years with a Glasgow Coma Scale score of 4-8 presenting within 8 hours after injury) who were randomized for a placebo-controlled Phase II trial of progesterone with or without hypothermia, the authors serially analyzed serum biomarkers (S100-B, glial fibrillary acidic protein [GFAP], neuron-specific enolase [NSE], tumor necrosis factor-α, interleukin-6 [IL-6], estrogen [Eg], and progesterone [Pg]). This analysis was performed using the sandwich enzyme-linked immunosorbent assay technique at admission and 7 days later for 86 patients, irrespective of assigned group. The long-term predictive values of serum biomarkers for dichotomized Glasgow Outcome Scale (GOS) score, functional independence measure, and survival status at 6 and 12 months were analyzed using an adjusted binary logistic regression model and receiver operating characteristic curve. RESULTS A favorable GOS score (4-5) at 1 year was predicted by higher admission IL-6 (above 108.36 pg/ml; area under the curve [AUC] 0.69, sensitivity 52%, and specificity 78.6%) and Day 7 Pg levels (above 3.15 ng/ml; AUC 0.79, sensitivity 70%, and specificity 92.9%). An unfavorable GOS score (1-3) at 1 year was predicted by higher Day 7 GFAP levels (above 9.50 ng/ml; AUC 0.82, sensitivity 78.6%, and specificity 82.4%). Survivors at 1 year had significantly higher Day 7 Pg levels (above 3.15 ng/ml; AUC 0.78, sensitivity 66.7%, and specificity 90.9%). Nonsurvivors at 1 year had significantly higher Day 7 GFAP serum levels (above 11.14 ng/ml; AUC 0.81, sensitivity 81.8%, and specificity 88.9%) and Day 7 IL-6 serum levels (above 71.26 pg/ml; AUC 0.87, sensitivity 81.8%, and specificity 87%). In multivariate logistic regression analysis, independent predictors of outcome at 1 year were serum levels of Day 7 Pg (favorable GOS-OR 3.24, CI 1.5-7, p = 0.003; and favorable survival-OR 2, CI 1.2-3.5, p = 0.01); admission IL-6 (favorable GOS-OR 1.04, CI 1.00-1.08, p = 0.04); and Day 7 GFAP (unfavorable GOS-OR 0.79, CI 0.65-0.95, p = 0.01; and unfavorable survival-OR 0.80, CI 0.66-0.96, p = 0.01). CONCLUSIONS Serial Pg, GFAP, and IL-6 monitoring could aid in prognosticating outcomes in patients with acute sTBI. A cause and effect relationship or a mere association of these biomarkers to outcome needs to be further studied for better understanding of the pathophysiology of sTBI and for choosing potential therapeutic targets.

The degree of inflammatory response with cytokine release is associated with poor outcomes after aneurysmal subarachnoid hemorrhage (SAH). Previously, we reported on an association between systemic IL-6 levels and clinical outcome in patients with aneurysmal SAH. The intention was to assess the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen on the inflammatory response after SAH. Our method involved exploratory analysis of data and samples collected within a previous study. In 138 patients with SAH, systemic interleukin (IL-6) and c-reactive protein (CRP) were measured daily up to day 14 after SAH. The correlations among the cumulatively applied amount of NSAIDs, inflammatory parameters, and clinical outcome were calculated. An inverse correlation between cumulatively applied NSAIDs and both IL-6 and CRP levels was found (r = -0.437, p < 0.001 and r = -0.369, p < 0.001 respectively). Multivariable linear regression analysis showed a cumulative amount of NSAIDs to be independently predictive for systemic IL-6 and CRP levels. The cumulative amount of NSAIDs reduced the odds for unfavorable outcome, defined as Glasgow outcome scale 1-3. The results indicate a potential beneficial effect of NSAIDs in patients with SAH in terms of ameliorating inflammatory response, which might have an impact on outcome.

Early onset in bipolar disorder (BPD) has been associated with greater familial risk and unfavorable clinical outcomes. We pooled data from seven international centers to analyze the relationships of family history and symptomatic as well as functional measures of adult morbidity to onset age, or onset in childhood (age <12), adolescence (12-18), or adulthood (19-55 years). In 1,665 adult, DSM-IV BPD-I patients, onset was 5% in childhood, 28% in adolescence, and 53% at peak ages 15-25. Adolescent and adult onset did not differ by symptomatic morbidity (episodes/year, percentage of months ill, co-morbidity, hospitalization, suicide attempts) or family history. Indications of favorable adult functional outcomes (employment, living independently, marriage and children, and a composite measure including education) ranked, by onset: adult > adolescent > child. Onset in childhood versus adolescence had more episodes/year and more psychiatric co-morbidity. Family history was most prevalent with childhood onset, similar over onset ages 12-40 years, and fell sharply thereafter. Multivariate modeling sustained the impression that family history and poor functional, but not symptomatic, outcomes were associated with younger, especially childhood onset. Early onset was more related to poor functional outcomes than greater symptomatic morbidity, with least favorable outcomes and greater family history with childhood onset. PMID:22295008

A large number of randomized clinical trials with important health outcomes are completed each year. Those with favorable findings are typically reported and published rapidly, while the publication of those with unfavorable results is often delayed or given a positive "spin." This observation applies primarily to industry-sponsored trials. Our objectives are to discuss the responsibility of pharmaceutical firms to the public with respect to timely, complete, and unbiased information from all randomized clinical trials and to propose solutions for improvements. We believe that in addition to financial obligations to their shareholders, pharmaceutical companies have social responsibilities to the public and to health care providers. However, private markets do not reward or compel optimal disclosure of drug safety or inferiority information on a voluntary basis. A problem which has not previously been identified relates to non-comparability of drugs. A case report from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) illustrates how public interests may be violated due to failure to inform about drug inferiority. The current system for dissemination of relevant medical information could be improved if all involved parties collaborated fully. However, full disclosure of trial results is unlikely when research results are unfavorable to the firm. We conclude that expanded government regulations will be required for a satisfactory solution to the problem. PMID:15239846

Insight and illness perception are two concepts of interest in the study of factors related to clinical outcome in patients with psychosis. Insight implies a risk of emotional distress for the patient. Illness perceptions, regardless of their accuracy, might be favorable or not to illness. Literature provides evidence of significant correlates of these factors with clinical outcome, but they are rarely included in a single study. 1) assessing insight and illness perception in a sample of Mexican patients who have experienced psychosis and, 2) analyzing how insight and illness perception relate to each other and how they relate to clinical status (i.e., positive, negative, and general psychopathology, depression, and anxiety). Sixty-one participants (55.7% females) were recruited from a public psychiatric hospital; insight and illness perceptions were assessed with the SUMD and the Brief-IPQ, respectively. Clinical status was assessed with the PANSS, CDS and BAI scales. Participants showed good insight, favorable illness perceptions for the cognitive and comprehension dimensions, but unfavorable for the emotional dimension. Clinical status of sample was characterized by mild symptoms. Poor insight related to positive symptoms and general psychopathology. Cognitive and emotional perceptions of illness were significantly associated to most clinical status parameters, whereas comprehension showed no significant results. The study not only replicates the significant association on insight and illness perception with clinical outcome, but shows how their patterns of interactions are different, reinforcing the idea that they are two distinct factors worthy of being habitually acknowledged in research and clinical practice.

Background Traumatic brain injury (TBI) is a major contributor to morbidity and mortality. Computerized tomography (CT) scanning of the brain is essential for diagnostic screening of intracranial injuries in need of neurosurgical intervention, but may also provide information concerning patient prognosis and enable baseline risk stratification in clinical trials. Novel CT scoring systems have been developed to improve current prognostic models, including the Stockholm and Helsinki CT scores, but so far have not been extensively validated. The primary aim of this study was to evaluate the Stockholm and Helsinki CT scores for predicting functional outcome, in comparison with the Rotterdam CT score and Marshall CT classification. The secondary aims were to assess which individual components of the CT scores best predict outcome and what additional prognostic value the CT scoring systems contribute to a clinical prognostic model. Methods and findings TBI patients requiring neuro-intensive care and not included in the initial creation of the Stockholm and Helsinki CT scoring systems were retrospectively included from prospectively collected data at the Karolinska University Hospital (n = 720 from 1 January 2005 to 31 December 2014) and Helsinki University Hospital (n = 395 from 1 January 2013 to 31 December 2014), totaling 1,115 patients. The Marshall CT classification and the Rotterdam, Stockholm, and Helsinki CT scores were assessed using the admission CT scans. Known outcome predictors at admission were acquired (age, pupil responsiveness, admission Glasgow Coma Scale, glucose level, and hemoglobin level) and used in univariate, and multivariable, regression models to predict long-term functional outcome (dichotomizations of the Glasgow Outcome Scale [GOS]). In total, 478 patients (43%) had an unfavorable outcome (GOS 1–3). In the combined cohort, overall prognostic performance was more accurate for the Stockholm CT score (Nagelkerke’s pseudo-R2 range 0.24–0.28) and the Helsinki CT score (0.18–0.22) than for the Rotterdam CT score (0.13–0.15) and Marshall CT classification (0.03–0.05). Moreover, the Stockholm and Helsinki CT scores added the most independent prognostic value in the presence of other known clinical outcome predictors in TBI (6% and 4%, respectively). The aggregate traumatic subarachnoid hemorrhage (tSAH) component of the Stockholm CT score was the strongest predictor of unfavorable outcome. The main limitations were the retrospective nature of the study, missing patient information, and the varying follow-up time between the centers. Conclusions The Stockholm and Helsinki CT scores provide more information on the damage sustained, and give a more accurate outcome prediction, than earlier classification systems. The strong independent predictive value of tSAH may reflect an underrated component of TBI pathophysiology. A change to these newer CT scoring systems may be warranted. PMID:28771476

High-risk neuroblastoma remains a therapeutic challenge for pediatric oncologists. The Polo-like kinase 1 (PLK1) is highly expressed in many human cancers and is a target of the novel small-molecule inhibitor BI 2536, which has shown promising anticancer activity in adult malignancies. Here, we investigated the effect of BI 2536 on neuroblastoma cells in vitro and in vivo to explore PLK1 as a potential target in high-risk neuroblastoma therapy. PLK1 transcript levels were analyzed by microarrays in 476 primary neuroblastoma specimens, and correlation with prognostic markers and patient outcome was examined. To explore the effect of PLK1 inhibition on neuroblastoma cells, 7 cell lines were treated with BI 2536 and changes in growth properties were determined. Furthermore, nude mice with IMR-32 and SK-N-AS xenografts were treated with BI 2536. PLK1 is highly expressed in unfavorable neuroblastoma and in neuroblastoma cell lines. Expression of PLK1 is associated with unfavorable prognostic markers such as stage 4, age >18 months, MYCN amplification, unfavorable gene expression-based classification, and adverse patient outcome (P < 0.001 each). On treatment with nanomolar doses of BI 2536, all neuroblastoma cell lines analyzed showed significantly reduced proliferation, cell cycle arrest, and cell death. Moreover, BI 2536 abrogated growth of neuroblastoma xenografts in nude mice. Elevated PLK1 expression is significantly associated with high-risk neuroblastoma and unfavorable patient outcome. Inhibition of PLK1 using BI 2536 exhibits strong antitumor activity on human neuroblastoma cells in vitro and in vivo, opening encouraging new perspectives for the treatment of high-risk neuroblastoma. ©2010 AACR.

To determine delivery outcome in women undergoing induction of labor for postdate pregnancy in relation to fetal gender. A total of 365 nulliparous and 127 multiparous women carrying singleton postdate pregnancies with unfavorable cervix were enrolled. Clinical characteristics and delivery outcome were analyzed in relation to fetal gender. Women carrying male fetuses showed higher rate of caesarean section than those carrying females, in both nulliparous and multiparous women. Moreover, women carrying male fetuses presented more frequently with (i) interval between induction of labor and delivery >24 hours (P < .0002); (ii) augmentation of labor after cervical ripening (P < .0391); (iii) meconium-stained liquor (P< .0126); and (iv) higher neonatal weight (P < .0011) than those carrying females. Male fetuses are more likely to be associated with higher rates of cesarean section. In maternal fetal medicine, gender differences may add prognostic information on the delivery outcome in women induced for postdate pregnancy.

Aim To describe our experience in the clinical application of extracorporeal life support (ECLS) and analyze whether ECLS leads to acceptable clinical outcomes in patients with cardiac failure. Methods Data from clinical database of University Hospital Center Zagreb, Croatia, on 75 patients undergoing ECLS support from 2009 to 2014 due to cardiac failure were retrospectively analyzed. Outcomes were defined as procedural and clinical outcomes. ECLS as a primary procedure and ECLS as a postcardiotomy procedure due to inability to wean from cardiopulmonary bypass were analyzed. Results ECLS was used in 75 adult patients, and in 24 (32%) of those procedural success was noted. ECLS was implemented as a primary procedure in 36 patients and as a postcardiotomy procedure in 39 patients. Nine out of 39 (23.08%) patients had postcardiotomy ECLS after heart transplantation. Bleeding complications occurred in 30 (40%) patients, both in primary (11/36 patients) and postcardiotomy group (19/39 patients). ECLS was established by peripheral approach in 46 patients and by central cannulation in 27 patients. In 2 patients, combined cannulation was performed, with an inflow cannula placed into the right atrium and an outflow cannula placed into the femoral artery. Eleven patients treated with peripheral approach had ischemic complications. Conclusion ECLS is a useful tool in the treatment of patients with refractory cardiac failure and its results are encouraging in patients who otherwise have an unfavorable prognosis. PMID:25559831

The international scope of critical neurologic insults in children is unknown. Our objective was to assess the prevalence and outcomes of children admitted to PICUs with acute neurologic insults. Prospective study. Multicenter (n = 107 PICUs) and multinational (23 countries, 79% in North America and Europe). Children 7 days to 17 years old admitted to the ICU with new traumatic brain injury, stroke, cardiac arrest, CNS infection or inflammation, status epilepticus, spinal cord injury, hydrocephalus, or brain mass. None. We evaluated the prevalence and outcomes of children with predetermined acute neurologic insults. Child and center characteristics were recorded. Unfavorable outcome was defined as change in pre-post insult Pediatric Cerebral Performance Category score greater than or equal to 2 or death at hospital discharge or 3 months, whichever came first. Screening data yielded overall prevalence of 16.2%. Of 924 children with acute neurologic insults, cardiac arrest (23%) and traumatic brain injury (19%) were the most common. All-cause mortality at hospital discharge was 12%. Cardiac arrest subjects had highest mortality (24%), and traumatic brain injury subjects had the most unfavorable outcomes (49%). The most common neurologic insult was infection/inflammation in South America, Asia, and the single African site but cardiac arrest in the remaining regions. Neurologic insults are a significant pediatric international health issue. They are frequent and contribute substantial morbidity and mortality. These data suggest a need for an increased focus on acute critical neurologic diseases in infants and children including additional research, enhanced availability of clinical resources, and the development of new therapies.

Merkel cell carcinoma (MCC) is a clinically aggressive neuroendocrine skin cancer; 80% of the cases are associated with the Merkel cell polyomavirus (MCPyV). We previously reported that MCPyV-negative MCCs have more irregular nuclei with abundant cytoplasm and significantly unfavorable outcomes than do MCPyV-positive MCCs. These results suggest that some cell adhesion or structural stabilization molecules are differently expressed depending on MCPyV infection status. Thus, we investigated the association of prognosis or MCPyV infection status in MCCs with cell adhesion molecule 1 (CADM1)/differentially expressed in adenocarcinoma of the lung protein 1 (DAL-1)/membrane protein, palmitoylated 3 (MPP3) tripartite complex and mal T-cell differentiation protein (MAL) expression, which play important roles in cell adhesion and oncogenesis and are related to cancer outcomes in various malignancies, to elucidate the role of these molecules. We analyzed the pathological and molecular characteristics of 26 MCPyV-positive and 15 MCPyV-negative MCCs. Univariate Cox regression analysis showed that advanced age (hazard ratio [HR], 8.249; P = .007) and high CADM1 expression (HR, 5.214; P = .012) were significantly unfavorable overall survival parameters, whereas MCPyV infection (HR, 0.043, P < .001) and lower MAL expression (HR, 0.273; P = .018) were significantly favorable. On multivariate analysis, only MCPyV infection was significantly favorable for overall survival (HR, 0.04; P = .005). Hypermethylation of CADM1, DAL-1, and MAL promoters was detected in 1 of 18, 15 of 27, and 1 of 13 cases, respectively. Double immunostaining for cytokeratin 20 and CADM1, DAL-1, or MAL showed that nonneoplastic Merkel cells expressed DAL-1 and MAL but not CADM1. This study revealed that MCPyV-negative MCCs significantly expressed higher CADM1 and lower MAL than MCPyV-positive MCCs; these expression levels were markedly related to unfavorable outcomes. These data will give us important insights to develop novel molecular target therapies for MCCs. Copyright © 2015 Elsevier Inc. All rights reserved.

Traumatic brain injury is a significant cause of morbidity and mortality in children. Cerebral autoregulation disturbance after traumatic brain injury is associated with worse outcome. Pressure reactivity is a fundamental component of cerebral autoregulation that can be estimated using the pressure-reactivity index, a correlation between slow arterial blood pressure, and intracranial pressure fluctuations. Pressure-reactivity index has shown prognostic value in adult traumatic brain injury, with one study confirming this in children. Pressure-reactivity index can identify a cerebral perfusion pressure range within which pressure reactivity is optimal. An increasing difference between optimal cerebral perfusion pressure and cerebral perfusion pressure is associated with worse outcome in adult traumatic brain injury; however, this has not been investigated in children. Our objective was to study pressure-reactivity index and optimal cerebral perfusion pressure in pediatric traumatic brain injury, including associations with outcome, age, and cerebral perfusion pressure. Prospective observational study. ICU, Royal Children's Hospital, Melbourne, Australia. Patients with traumatic brain injury who are 6 months to 16 years old, are admitted to the ICU, and require arterial blood pressure and intracranial pressure monitoring. None. Arterial blood pressure, intracranial pressure, and end-tidal CO2 were recorded electronically until ICU discharge or monitoring cessation. Pressure-reactivity index and optimal cerebral perfusion pressure were computed according to previously published methods. Clinical data were collected from electronic medical records. Outcome was assessed 6 months post discharge using the modified Glasgow Outcome Score. Thirty-six patients were monitored, with 30 available for follow-up. Pressure-reactivity index correlated with modified Glasgow Outcome Score (Spearman ρ = 0.42; p = 0.023) and was higher in patients with unfavorable outcome (0.23 vs -0.09; p = 0.0009). A plot of pressure-reactivity index averaged within 5 mm Hg cerebral perfusion pressure bins showed a U-shape, reaffirming the concept of cerebral perfusion pressure optimization in children. Optimal cerebral perfusion pressure increased with age (ρ = 0.40; p = 0.02). Both the duration and magnitude of negative deviations in the difference between cerebral perfusion pressure and optimal cerebral perfusion pressure were associated with unfavorable outcome. In pediatric patients with traumatic brain injury, pressure-reactivity index has prognostic value and can identify cerebral perfusion pressure targets that may differ from treatment protocols. Our results suggest but do not confirm that cerebral perfusion pressure targeting using pressure-reactivity index as a guide may positively impact on outcome. This question should be addressed by a prospective clinical study.

The WNT/β-catenin pathway plays an important role in pancreatic cancer carcinogenesis. We evaluated the correlation between aberrant β-catenin pathway activation and the prognosis pancreatic cancer, and the potential of applying the β-catenin pathway inhibitor FH535 to pancreatic cancer treatment. Meta-analysis and immunohistochemistry showed that abnormal β-catenin pathway activation was associated with unfavorable outcome. FH535 repressed pancreatic cancer xenograft growth in vivo. Gene Ontology (GO) analysis of microarray data indicated that target genes responding to FH535 participated in stemness maintenance. Real-time PCR and flow cytometry confirmed that FH535 downregulated CD24 and CD44, pancreatic cancer stem cell (CSC) markers, suggesting FH535 impairs pancreatic CSC stemness. GO analysis of β-catenin chromatin immunoprecipitation sequencing data identified angiogenesis-related gene regulation. Immunohistochemistry showed that higher microvessel density correlated with elevated nuclear β-catenin expression and unfavorable outcome. FH535 repressed the secretion of the proangiogenic cytokines vascular endothelial growth factor (VEGF), interleukin (IL)-6, IL-8, and tumor necrosis factor-α, and also inhibited angiogenesis in vitro and in vivo. Protein and mRNA microarrays revealed that FH535 downregulated the proangiogenic genes ANGPT2, VEGFR3, IFN-γ, PLAUR, THPO, TIMP1, and VEGF. FH535 not only represses pancreatic CSC stemness in vitro, but also remodels the tumor microenvironment by repressing angiogenesis, warranting further clinical investigation. PMID:27323403

Objectives To examine the relationship between cigarette smoking and incidence and mortality rates of pulmonary tuberculosis (TB) and treatment outcomes. Materials From 1995-2010, we analyzed data from 1062 patients with TB and from 2001-2004, 2951 contacts in Southern Mexico. Patients with acid-fast bacilli or Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and mycobacteriological evaluation and received treatment by the local DOTS program. Results Consumers of 1-10 (LS) or 11 or more (HS) cigarettes per day incidence (1.75 and 11.79) and mortality (HS,17.74) smoker-nonsmoker rate ratios were significantly higher for smokers. Smoker population was more likely to experience unfavorable treatment outcomes (HS, adjusted OR 2.36) and retreatment (LS and HS, adjusted hazard ratio (HR) 2.14 and 2.37). Contacts that smoked had a higher probability of developing active TB (HR 2.38) during follow up. Conclusions Results indicate the need of incorporating smoking prevention and cessation, especially among men, into international TB control strategies. PMID:22982014

Although most breast abscesses can be treated with the current first-line treatment of antibiotics by needle aspiration, the therapeutic duration is lengthy and recurrences often occur. Therefore, we aimed to investigate the clinical efficacy of the Mammotome biopsy system (Johnson & Johnson Corp., New Brunswick, NJ) in a cohort of patients with breast abscesses. Forty lactating and 30 nonlactating breast abscess patients with unfavorable outcomes with antibiotic treatment and/or needle aspiration failure were recruited and treated with the Mammotome biopsy system. Skin inflammation of all patients disappeared within 6 days with no recurrence. The clinical outcomes in patients with an abscess size ≤ 3.5 cm was significantly better than those with an abscess size >3.5 cm (P = .025). The Mammotome biopsy system, an effective treatment strategy that is minimally invasive and less damaging, in combination with appropriate antibiotic therapy can be used safely as the first-line approach to breast abscess management.

To clarify the clinical role of traumatic subarachnoid hemorrhage (tSAH), stratified analysis with grouping of tSAH was performed. Their blood flow changes and correlations with outcome were assayed. One hundred seventeen tSAH patients were classified into several groups according to their initial computerized tomography scans. Group I included patients with tSAH only in the posterior interhemispheric fissure, whereas Group II contained patients with tSAH located elsewhere. Group II was further subdivided into IIa, little SAH; IIb, extensive SAH; IIc, little SAH with intraventricular hemorrhage (IVH); and IId, extensive SAH with IVH. The cerebral blood flow velocity was monitored using transcranial Doppler sonography (TCD). Both age and initial coma scale were independent predictors of poor outcome. The poor outcome rates in various subgroups of tSAH increased stepwise from group I to group IId (I, 7.4%; IIa, 18.4%; IIb, 33.3%; IIc, 62.5%; and IId, 90.9%) (p = 0.0010). Stratified analyses revealed that patients with extensive tSAH (group IIb + IId) were more likely to have unfavorable outcomes (47.7%) than patients with little tSAH (group IIa + IIc) (26.1%) (p = 0.0185); patients with IVH (group IIc + IId) also displayed a higher incidence (78.9%) of poor outcomes than patients without IVH (group IIa + IIb) (25.4%) (p = 0.0030). TCD study demonstrated that patients with extensive tSAH (group IIb + IId) were more likely to have the vasospasm based on TCD criteria than did patients in group I and group IIa + IIc (37.5% vs. 5.9% and 7.7%, p = 0.0105). Notably, there was a tendency of worse outcome in patients with vasospasm on the basis of TCD-derived criteria than those without, with the unfavorable outcome rates being 47.4% and 24.7% (p = 0.0799). Age, initial coma scale, extensive tSAH, and IVH are independent predictors of poor outcome in the cohort of tSAH patients. Statistically, patients with extensive tSAH are significantly more likely to have vasospasm.

Area social deprivation is associated with unfavorable health outcomes of residents across the full clinical course of cancer from the stage at diagnosis through survival. We sought to determine whether area social factors are associated with the area health care supply. We studied the area supply of health services required for the provision of guideline-recommended care for patients with breast cancer and colorectal cancer (CRC) in each of the following three distinct clinical domains: screening, treatment, and post-treatment surveillance. We characterized area social factors in 3,096 urban zip code tabulation areas by using Census Bureau data and the health care supply in the corresponding 465 hospital service areas by using American Hospital Association, American Medical Association, and US Food and Drug Administration data. In two-level hierarchical models, we assessed associations between social factors and the supply of health services across areas. We found no clear associations between area social factors and the supply of health services essential to the provision of guideline recommended breast cancer and CRC care in urban areas. The measures of health service included the supply of physicians who facilitate screening, treatment, and post-treatment care and the supply of facilities required for the same services. Because we found that the supply of types of health care required for the provision of guideline-recommended cancer care for patients with breast cancer and CRC did not vary with markers of area socioeconomic disadvantage, it is possible that previously reported unfavorable breast cancer and CRC outcomes among individuals living in impoverished areas may have occurred despite an apparent adequate area health care supply.

1) To investigate different aspects of paragraph reading in Mandarin-speaking students with cochlear implants (CIs) and the factors associated with unfavorable outcomes, and 2) to understand the replaceability of a paragraph-reading test with a sentence-reading test. Cross-sectional, case-controlled study. Fifty-three students with CIs (aged 11.0 ± 1.4 years) and 53 grade- and gender-matched children with normal hearing (NH) participated in the study. A paragraph-reading comprehension test was conducted. Sentence and word reading, speech perception, language skills, and child/family characteristics were examined. An unfavorable paragraph-reading outcome was defined as a score lower than one standard deviation below the NH mean. The CI subjects had significantly worse paragraph-reading comprehension than did the NH controls (P = 0.017, d = 0.54). Their performance in grades 5 to 6 was not significantly higher than of those with NH in grades 2 to 4. The CI children's abilities to understand semantics (P = 0.012) and syntax (P = 0.020) significantly fell behind the NH controls in grades 2 to 4, and the lag continued in grades 5 to 6 (P = 0.039, P = 0.002, respectively). Grade and sentence reading were independently associated with unfavorable paragraph-reading outcomes (R(2)  = 0.453). The optimal sensitivity and specificity of the sentence-reading test in identifying unfavorable paragraph-reading outcomes were 90.9% and 90.0%, respectively (area under the curve = 0.923). Specialists should pay attention to CI students' development of different reading skills. Paragraph-reading tests enable a multidimensional evaluation of reading competence. Use of sentence-reading tests is suggested only as a tool for preliminary screening for basic reading capacities. 3b. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Nutritional Care of Gastric Cancer Patients with Clinical Outcomes and Complications: A Review.

PubMed

Choi, Wook Jin; Kim, Jeongseon

2016-04-01

The incidence and mortality of gastric cancer have been steadily decreased over the past few decades. However, gastric cancer is still one of the leading causes of cancer deaths across many regions of the world, particularly in Asian countries. In previous studies, nutrition has been considered one of significant risk factors in gastric cancer patients. Especially, malnourished patients are at greater risk of adverse clinical outcomes (e.g., longer hospital stay) and higher incidence of complications (e.g., wound/infectious complications) compared to well-nourished patients. Malnutrition is commonly found in advanced gastric cancer patients due to poor absorption of essential nutrients after surgery. Therefore, nutritional support protocols, such as early oral and enternal feeding, have been proposed in many studies, to improve unfavorable clinical outcomes and to reduce complications due to delayed application of oral nutritional support or parental feeding. Also, the supplied with enternal immune-enriched diet had more benefits in improving clinical outcomes and fewer complications compared to a group supplied with control formula. Using nutritional screening tools, such as nutritional risk index (NRI) and nutritional risk screening (NRS 2002), malnourished patients showed higher incidence of complications and lower survival rates than non-malnourished patients. However, a long-term nutritional intervention, such as nutritional counseling, was not effective in the patients. Therefore, early assessment of nutritional status in patients using a proper nutritional screening tool is suggested to prevent malnutrition and adverse health outcomes. Further studies with numerous ethnic groups may provide stronger scientific evidences in association between nutritional care and recovery from surgery in patients with gastric cancer.

Abstract Objective: This article examines the characteristics of impulsive aggression (IA) as a comorbidity in children and adolescents with attention-deficit/hyperactivity disorder (ADHD), focusing on its incidence, impact on ADHD outcomes, need for timely intervention, and limitations of current treatment practices. Methods: Relevant literature was retrieved with electronic searches in PubMed and PsycINFO using the search strategy of “ADHD OR attention deficit hyperactivity disorder” AND “impulsive aggression OR reactive aggression OR hostile aggression OR overt aggression” AND “pediatric OR childhood OR children OR pre-adolescent OR adolescent” with separate searches using review OR clinical trial as search limits. Key articles published before the 2007 Expert Consensus Report on IA were identified using citation analysis. Results: More than 50% of preadolescents with ADHD combined subtype reportedly display clinically significant aggression, with impulsive aggression being the predominant subtype. Impulsive aggression is strongly predictive of a highly unfavorable developmental trajectory characterized by the potential for persistent ADHD, increasing psychosocial burden, accumulating comorbidities, serious lifelong functional deficits across a broad range of domains, delinquency/criminality, and adult antisocial behavior. Impulsive aggression, which triggers peer rejection and a vicious cycle of escalating dysfunction, may be a key factor in unfavorable psychosocial outcomes attributed to ADHD. Because severe aggressive behavior does not remit in many children when treated with primary ADHD therapy (i.e., stimulants and behavioral therapy), a common practice is to add medication of a different class to specifically target aggressive behavior. Conclusions: Impulsive aggression in children and adolescents with ADHD is a serious clinical and public health problem. Although adjunctive therapy with an aggression-targeted agent is widely recommended when aggressive behaviors do not remit with primary ADHD therapy, empirical evidence does not currently support the use of any specific agent. Randomized controlled trials are needed to identify aggression-targeted agents with favorable benefit–risk profiles. PMID:26744906

Background Epilepsy surgery is a potentially curative treatment option for pharmacoresistent patients. If non-invasive methods alone do not allow to delineate the epileptogenic brain areas the surgical candidates undergo long-term monitoring with intracranial EEG. Visual EEG analysis is then used to identify the seizure onset zone for targeted resection as a standard procedure. Methods Despite of its great potential to assess the epileptogenicty of brain tissue, quantitative EEG analysis has not yet found its way into routine clinical practice. To demonstrate that quantitative EEG may yield clinically highly relevant information we retrospectively investigated how post-operative seizure control is associated with four selected EEG measures evaluated in the resected brain tissue and the seizure onset zone. Importantly, the exact spatial location of the intracranial electrodes was determined by coregistration of pre-operative MRI and post-implantation CT and coregistration with post-resection MRI was used to delineate the extent of tissue resection. Using data-driven thresholding, quantitative EEG results were separated into normally contributing and salient channels. Results In patients with favorable post-surgical seizure control a significantly larger fraction of salient channels in three of the four quantitative EEG measures was resected than in patients with unfavorable outcome in terms of seizure control (median over the whole peri-ictal recordings). The same statistics revealed no association with post-operative seizure control when EEG channels contributing to the seizure onset zone were studied. Conclusions We conclude that quantitative EEG measures provide clinically relevant and objective markers of target tissue, which may be used to optimize epilepsy surgery. The finding that differentiation between favorable and unfavorable outcome was better for the fraction of salient values in the resected brain tissue than in the seizure onset zone is consistent with growing evidence that spatially extended networks might be more relevant for seizure generation, evolution and termination than a single highly localized brain region (i.e. a “focus”) where seizures start.

The survival rate among patients with intermediate-risk neuroblastoma who receive dose-intensive chemotherapy is excellent, but the survival rate among patients who receive reduced doses of chemotherapy for shorter periods of time is not known. We conducted a prospective, phase 3, nonrandomized trial to determine whether a 3-year estimated overall survival of more than 90% could be maintained with reductions in the duration of therapy and drug doses, using a tumor biology-based therapy assignment. Eligible patients had newly diagnosed, intermediate-risk neuroblastoma without MYCN amplification; these patients included infants (<365 days of age) who had stage 3 or 4 disease, children (≥365 days of age) who had stage 3 tumors with favorable histopathological features, and infants who had stage 4S disease with a diploid DNA index or unfavorable histopathological features. Patients who had disease with favorable histopathological features and hyperdiploidy were assigned to four cycles of chemotherapy, and those with an incomplete response or either unfavorable feature were assigned to eight cycles. Between 1997 and 2005, a total of 479 eligible patients were enrolled in this trial (270 patients with stage 3 disease, 178 with stage 4 disease, and 31 with stage 4S disease). A total of 323 patients had tumors with favorable biologic features, and 141 had tumors with unfavorable biologic features. Ploidy, but not histopathological features, was significantly predictive of the outcome. Severe adverse events without disease progression occurred in 10 patients (2.1%), including secondary leukemia (in 3 patients), death from infection (in 3 patients), and death at surgery (in 4 patients). The 3-year estimate (±SE) of overall survival for the entire group was 96±1%, with an overall survival rate of 98±1% among patients who had tumors with favorable biologic features and 93±2% among patients who had tumors with unfavorable biologic features. A very high rate of survival among patients with intermediate-risk neuroblastoma was achieved with a biologically based treatment assignment involving a substantially reduced duration of chemotherapy and reduced doses of chemotherapeutic agents as compared with the regimens used in earlier trials. These data provide support for further reduction in chemotherapy with more refined risk stratification. (Funded by the National Cancer Institute; ClinicalTrials.gov number, NCT00003093.)

The presence of anaplastic features has been known to correlate with poor clinical outcome in various pediatric malignancies, including Wilms tumor and medulloblastoma but not in rhabdomyosarcoma. Aim was to study the frequency of anaplasia at presentation in childhood rhabdomyosarcoma and its relationship to clinical and pathological characteristics as well as to outcome. Anaplasia was retrospectively assessed in 105 consecutive pediatric rhabdomyosarcoma patients who were registered at the Children's Cancer Hospital in Egypt (CCHE) during the period from July 2007 till the end of May 2010. Anaplasia was diagnosed in 18 patients (17.1%), focal in 10 (9.5%) and diffuse in 8 (7.6%). The distribution of anaplasia was found to be more common in older patients having age⩾10 years. Also it was more likely to occur in the high risk group and in tumors with unfavorable histology (alveolar subtype), and stage IV. The 3-year failure free survival rates for patients with and without anaplasia were 27.8±10.6% and 53.4±5.8%, respectively (p=0.014) and the 3-year overall survival rates were 35.3±11.6% and 61±6%, respectively (p=0.019). The frequency of anaplasia in pediatric patients with rhabdomyosarcoma in our study was 17.1%. The presence of anaplasia had statistically significant worse clinical outcome.

To compare obesity-related factors between female nurses with favorable work schedules (WSs) and unfavorable WSs. In a cross-sectional study, 1724 female nurses were stratified by WS (favorable vs unfavorable). For each schedule type, the odds of obesity were related to health behaviors, home demands, and job stress using logistic regression models. Among nurses with unfavorable WSs, healthy behaviors (exercise, sleep) were inversely associated with obesity, whereas for those with favorable WSs, obese nurses reported significantly more unhealthy behaviors (smoking, alcohol use; odds ratio [OR], 1.19; 95% confidence interval [CI], 1.02-1.38), more physical lifting of children/dependents (OR, 1.43; 95% CI, 1.06-1.93), having more nurse input into their jobs (OR, 1.21; 95% CI, 1.02-1.44), yet less boss support at work (OR, 0.83; 95% CI, 0.68-0.99). Considering impacts of WSs on obesity and potential obesity-related health outcomes, healthful scheduling should be provided to nurses.

A sustained proportion of advanced hepatocellular carcinoma (HCC) patients worldwide received either chemotherapy or sorafenib. However, to date, effective and convenient biomarkers to predict their therapeutic outcomes remained elusive. Hypothyroidism was associated with favorable anticancer treatment outcomes in several advanced cancers. Here, we aimed to investigate the potential of using thyroid-stimulating hormone (TSH) and free T4 (FT4) levels as biomarkers to predict clinical outcomes in HCC patients receiving chemotherapy or sorafenib. Total 123 advanced HCC patients at Barcelona Clinical Liver Cancer Stage C were included. They were separated into two cohorts, one treated by sorafenib (n = 62) and the other by chemotherapy (n = 61). Clinical data including TSH and FT4 were retrieved and correlated with treatment outcomes. Because of restriction in local insurance policy, the baseline liver function reserve was better in patients receiving sorafenib. Therefore, the two cohorts were analyzed separately. The results showed that a higher (> median) TSH × FT4 value was independently associated with favorable time-to-tumor progression (P = 0.006) and overall survival (P = 0.002) if chemotherapy was provided; whereas it was associated with unfavorable time-to-tumor progression (P = 0.017) and overall survival (P = 0.001) if sorafenib was administrated. These opposite associations remained valid when patients with Child-Pugh class A liver function from either cohort were included for analysis. A novel thyroid function index, TSH × FT4, significantly predicted opposite clinical outcomes in advanced HCC patients receiving sorafenib or chemotherapy treatment. © 2018 John Wiley & Sons Australia, Ltd.

OBJECTIVE Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis. Limited literature exists defining risk factors associated with outcomes during initial hospitalization in these patients. In this study, the authors investigated patient demographics, clinical and hospital characteristics impacting short-term outcomes, and costs in adolescent patients undergoing surgical deformity correction for idiopathic scoliosis. Additionally, the authors elucidate the impact of hospital surgical volume on outcomes for these patients. METHODS Using the National Inpatient Sample database and appropriate International Classification of Diseases, 9th Revision codes, the authors identified adolescent patients (10-19 years of age) undergoing surgical deformity correction for idiopathic scoliosis during 2001-2014. For national estimates, appropriate weights provided by the Agency of Healthcare Research and Quality were used. Multivariable regression techniques were employed to assess the association of risk factors with discharge disposition, postsurgical neurological complications, length of hospital stay, and hospitalization costs. RESULTS Overall, 75,106 adolescent patients underwent surgical deformity correction. The rates of postsurgical complications were estimated at 0.9% for neurological issues, 2.8% for respiratory complications, 0.8% for cardiac complications, 0.4% for infections, 2.7% for gastrointestinal complications, 0.1% for venous thromboembolic events, and 0.1% for acute renal failure. Overall, patients stayed at the hospital for an average of 5.72 days (median 5 days) and on average incurred hospitalization costs estimated at $54,997 (median $47,909). As compared with patients at low-volume centers (≤ 50 operations/year), those undergoing surgical deformity correction at high-volume centers (> 50/year) had a significantly lower likelihood of an unfavorable discharge (discharge to rehabilitation) (OR 1.16, 95% CI 1.03-1.30, p = 0.016) and incurred lower costs (mean $33,462 vs $56,436, p < 0.001) but had a longer duration of stay (mean 6 vs 5.65 days, p = 0.002). In terms of neurological complications, no significant differences in the odds ratios were noted between high- and low-volume centers (OR 1.23, 95% CI 0.97-1.55, p = 0.091). CONCLUSIONS This study provides insight into the clinical characteristics of AIS patients and their postoperative outcomes following deformity correction as they relate to hospital volume. It provides information regarding independent risk factors for unfavorable discharge and neurological complications following surgery for AIS. The proposed estimates could be used as an adjunct to clinical judgment in presurgical planning, risk stratification, and cost containment.

Research among adults has consistently shown that people holding negative self-views prefer negative over positive feedback. The present study tested the hypothesis that this preference is less robust among pre-adolescents, such that it will be mitigated by a preceding positive event. Pre-adolescents (n = 75) holding positive or negative global self-esteem were randomized to a favorable or unfavorable peer evaluation outcome. Next, preferences for positive versus negative feedback were assessed using an unobtrusive behavioral viewing time measure. As expected, results showed that after being faced with the success outcome children holding negative self-views were as likely as their peers holding positive self-views to display a significant preference for positive feedback. In contrast, children holding negative self-views displayed a stronger preference for negative feedback after being faced with the unfavorable outcome that matched their pre-existing self-views.

The strengths and limitations of considering childhood-and adolescent-onset bipolar disorder (BD) separately versus together remain to be established. We assessed this issue. BD patients referred to the Stanford Bipolar Disorder Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD Affective Disorders Evaluation. Patients with childhood- and adolescent-onset were compared to those with adult-onset for 7 unfavorable bipolar illness characteristics with replicated associations with early-onset patients. Among 502 BD outpatients, those with childhood- (<13 years, N=110) and adolescent- (13-18 years, N=218) onset had significantly higher rates for 4/7 unfavorable illness characteristics, including lifetime comorbid anxiety disorder, at least ten lifetime mood episodes, lifetime alcohol use disorder, and prior suicide attempt, than those with adult-onset (>18 years, N=174). Childhood- but not adolescent-onset BD patients also had significantly higher rates of first-degree relative with mood disorder, lifetime substance use disorder, and rapid cycling in the prior year. Patients with pooled childhood/adolescent - compared to adult-onset had significantly higher rates for 5/7 of these unfavorable illness characteristics, while patients with childhood- compared to adolescent-onset had significantly higher rates for 4/7 of these unfavorable illness characteristics. Caucasian, insured, suburban, low substance abuse, American specialty clinic-referred sample limits generalizability. Onset age is based on retrospective recall. Childhood- compared to adolescent-onset BD was more robustly related to unfavorable bipolar illness characteristics, so pooling these groups attenuated such relationships. Further study is warranted to determine the extent to which adolescent-onset BD represents an intermediate phenotype between childhood- and adult-onset BD. Copyright © 2015 Elsevier B.V.

Purpose: To analyze the long-term outcomes in patients with skull base meningiomas (SBMNGs) treated with Gamma Knife radiosurgery (GKRS). Methods and Materials: Of the 98 consecutive patients with SBMNGs treated with GKRS between 1998 and 2002, 63 were followed up for more than 48 months. The mean ({+-}SD) age of the patients was 50 {+-} 12 years, the mean tumor volume was 6.5 cm{sup 3} (range, 0.5-18.4 cm{sup 3}), the mean marginal dose was 12.6 Gy (range, 7.0-20.0 Gy), and the mean follow-up duration was 77 {+-} 18 months. The mean number of shots was 13.7 {+-} 3.8. The tumormore » volume was decreased at the last follow-up in 28 patients (44.4%) and increased in 6 (9.6%). The actuarial tumor control rate was 90.2% at 5 years. No notable prognostic factor related to tumor control was identified. Ten patients (15.9%) with a cranial neuropathy showed unfavorable outcomes. The rate of improvement in patients with a cranial neuropathy was 45.1%. Age >70 years was likely correlated with an unfavorable outcome in patients with cranial neuropathy (odds ratio = 0.027; p = 0.025; 95% confidence interval 0.001-0.632). Cavernous sinus location was significantly associated with improvement of a cranial neuropathy (odds ratio = 7.314; p = 0.007; 95% confidence interval 1.707-31.34). Conclusions: Gamma Knife radiosurgery is an effective modality for the treatment of SBMNGs and provides favorable outcomes in patients with cranial neuropathy, even in the long-term follow-up period. However, radiosurgery for patients with no or only mild symptoms should be performed cautiously because neither complication rate is low enough to be negligible, especially in elderly patients. A cranial neuropathy by MNGs involving the cavernous sinus seems to have a higher chance of improvement after radiosurgery than other SBMNGs.« less

We recently showed that electroencephalography (EEG) patterns within the first 24 hours robustly contribute to multimodal prediction of poor or good neurological outcome of comatose patients after cardiac arrest. Here, we confirm these results and present a cost-minimization analysis. Early prognosis contributes to communication between doctors and family, and may prevent inappropriate treatment. A prospective cohort study including 430 subsequent comatose patients after cardiac arrest was conducted at intensive care units of two teaching hospitals. Continuous EEG was started within 12 hours after cardiac arrest and continued up to 3 days. EEG patterns were visually classified as unfavorable (isoelectric, low-voltage, or burst suppression with identical bursts) or favorable (continuous patterns) at 12 and 24 hours after cardiac arrest. Outcome at 6 months was classified as good (cerebral performance category (CPC) 1 or 2) or poor (CPC 3, 4, or 5). Predictive values of EEG measures and cost-consequences from a hospital perspective were investigated, assuming EEG-based decision- making about withdrawal of life-sustaining treatment in the case of a poor predicted outcome. Poor outcome occurred in 197 patients (51% of those included in the analyses). Unfavorable EEG patterns at 24 hours predicted a poor outcome with specificity of 100% (95% CI 98-100%) and sensitivity of 29% (95% CI 22-36%). Favorable patterns at 12 hours predicted good outcome with specificity of 88% (95% CI 81-93%) and sensitivity of 51% (95% CI 42-60%). Treatment withdrawal based on an unfavorable EEG pattern at 24 hours resulted in a reduced mean ICU length of stay without increased mortality in the long term. This gave small cost reductions, depending on the timing of withdrawal. Early EEG contributes to reliable prediction of good or poor outcome of postanoxic coma and may lead to reduced length of ICU stay. In turn, this may bring small cost reductions.

Cryptogenic organizing pneumonia (COP) generally responds well to corticosteroids with a favorable outcome. Rare cases of organizing pneumonia are rapidly progressive. Yousem et al. studied pathologic predictors of idiopathic bronchiolitis obliterans organizing pneumonia/COP with an unfavorable prognosis. Beardsley and Rassl proposed the name fibrosing organizing pneumonia (FOP). A 74-year-old female non-smoker presented with a 2-week history of dry cough followed by dyspnea and a fever. The clinical course was fulminant, but we successfully performed bronchoscopy. After the diagnosis of FOP, we treated the patient with mechanical ventilation and high-doses of steroids/immunosuppressants, which improved the disease. PMID:28502934

The investigation of molecular mechanisms of tumor cell behavior in small renal masses is required to achieve the better cancer survival. The aim of the study is to find molecular markers associated with outcome of patients with kidney tumors 7 cm or less. A homogenous group of 20 patients T1N0M0-1 (mean age 57.6 ± 2.2 years) with kidney cancer was selected for the present analysis. The content of transcription and growth factors was determined by ELISA. The levels of AKT-mTOR signaling pathway components were measured by Western blotting analysis. The molecular markers associated with unfavorable outcome of patients with kidney tumors 7 cm or less were high levels of NF-kB p50, NF-kB p65, HIF-1, HIF-2, VEGF and CAIX. AKT activation with PTEN loss also correlated with the unfavorable outcome of kidney cancer patients with tumor size 7 cm or less. It is observed that the biological features of kidney cancer could predict the outcome of patients.

This study uses data from three longitudinal experimental evaluations of US state welfare reform programs to examine whether program-induced changes in families’ reliance on sibling care are linked with the effects of welfare programs on selected schooling outcomes of high risk, low-income adolescents. The findings from two of the welfare programs indicate that increased reliance on sibling care was concomitant with unfavorable effects of the programs on adolescent schooling outcomes. In the third welfare program examined, the program did not yield any increases in the use of sibling care or unfavorable effects on adolescent schooling outcomes, suggesting that sibling care is one likely contributor to the negative effects of welfare programs on adolescent schooling outcomes. These findings are discussed in terms of the pattern of the programs’ effects on families’ income, as well as maternal work on nonstandard schedules, aside from the programs’ effects on maternal employment, which play contributory roles in shaping the extent to which welfare programs led to less favorable effects on the schooling outcomes of adolescents with younger siblings.

Objective To evaluate the effect of emergency department (ED) copayment levels on ED use and unfavorable clinical events. Data Source/Study Setting Kaiser Permanente–Northern California (KPNC), a prepaid integrated delivery system. Study Design In a quasi-experimental longitudinal study with concurrent controls, we estimated rates of ED visits, hospitalizations, ICU admissions, and deaths associated with higher ED copayments relative to no copayment, using Poisson random effects and proportional hazard models, controlling for patient characteristics. The study period began in January 1999; more than half of the population experienced an employer-chosen increase in their ED copayment in January 2000. Data Collection/Extraction Methods Using KPNC automated databases, the 2000 U.S. Census, and California state death certificates, we collected data on ED visits and unfavorable clinical events over a 36-month period (January 1999 through December 2001) among 2,257,445 commercially insured and 261,091 Medicare insured health system members. Principal Findings Among commercially insured subjects, ED visits decreased 12 percent with the $20–35 copayment (95 percent confidence interval [CI]: 11–13 percent), and 23 percent with the $50–100 copayment (95 percent CI: 23–24 percent) compared with no copayment. Hospitalizations, ICU admissions, and deaths did not increase with copayments. Hospitalizations decreased 4 percent (95 percent CI: 2–6 percent) and 10 percent (95 percent CI: 7–13 percent) with ED copayments of $20–35 and $50–100, respectively, compared with no copayment. Among Medicare subjects, ED visits decreased by 4 percent (95 percent CI: 3–6 percent) with the $20–50 copayments compared with no copayment; unfavorable clinical events did not increase with copayments, e.g., hospitalizations were unchanged (95 percent CI: −3 percent to +2 percent) with $20–50 ED copayments compared with no copayment. Conclusions Relatively modest levels of patient cost-sharing for ED care decreased ED visit rates without increasing the rate of unfavorable clinical events. PMID:16987303

Torok, Jordan A., E-mail: jordan.torok@dm.duke.edu; Wu, Yuan; Prosnitz, Leonard R.

Purpose: The German Hodgkin Study Group (GHSG) trial HD11 established 4 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and 30 Gy of radiation therapy (RT) as a standard for early stage (I, II), unfavorable Hodgkin lymphoma (HL). Additional cycles of ABVD may allow for a reduction in RT dose and improved toxicity profile. Methods and Materials: Patients treated with combined modality therapy at the Duke Cancer Institute for early stage, unfavorable HL by GHSG criteria from 1994 to 2012 were included. Patients who did not undergo post-chemotherapy functional imaging (positron emission tomography or gallium imaging) or who failed to achievemore » a complete response were excluded. Clinical outcomes were estimated using the Kaplan-Meier method. Late effects were also evaluated. Results: A total of 90 patients met inclusion criteria for analysis. Median follow-up was 5 years. Chemotherapy consisted primarily of ABVD (88%) with a median number of 6 cycles. The median dose of consolidation RT was 23.4 Gy. Four patients had relapses, 2 of which were in-field. Ten-year progression-free survival (PFS) and overall survival (OS) were 93% (95% confidence interval [CI]: 0.82-0.97) and 98% (95% CI: 0.92-0.99), respectively. For the subset of patients (n=46) who received 5 to 6 cycles of chemotherapy and ≤24 Gy, the 10-year PFS and OS values were 88% (95% CI: 70%-96%) and 98% (95% CI: 85% - 99%), respectively. The most common late effect was hypothyroidism (20%) with no cardiac complications. Seven secondary malignancies were diagnosed, with only 1 arising within the RT field. Conclusions: Lower doses of RT may be sufficient when combined with more than 4 cycles of ABVD for early stage, unfavorable HL and may result in a more favorable toxicity profile than 4 cycles of ABVD and 30 Gy of RT.« less

To compare induction of labor methods in patients attempting a trial of labor after cesarean (TOLAC) with an unfavorable cervix. This is a retrospective cohort study from patients attempting TOLAC from 2009 to 2013. Patients with a simplified Bishop score of three or less where labor was initiated with either a Cook balloon or oxytocin were included. Our primary outcome was mode of delivery. Our secondary outcomes included duration of labor and multiple maternal and neonatal morbidities. Two-hundred and fourteen women met inclusion criteria: 150 received oxytocin and 64 had the Cook balloon placed. The vaginal birth after cesarean delivery rate was significantly higher in the oxytocin group at 70.7% versus 50.0% in the Cook balloon group (p = 0.004). In the multivariable analysis, odds for cesarean delivery were two times higher with the Cook balloon than with oxytocin (Adjusted OR = 2.09, 95% CI = 1.05-4.18, p = 0.036). The duration of labor was longer with the Cook balloon versus oxytocin (21.9 versus 16.3 hours, p = 0.0002). There were no significant differences in maternal and neonatal health outcomes. Oxytocin induction of labor was associated with a higher rate of vaginal delivery and a shorter duration of labor compared to the Cook balloon in women undergoing TOLAC with an unfavorable cervix.

The aim of this study was to determine cephalometric factors that help predict favorable soft-tissue profile outcomes following treatment with the Class II Twin-block appliance. Pre- and post-treatment lateral cephalograms of 45 patients treated with the Class II Twin-block appliance were retrospectively analyzed. Profile silhouettes were drawn from the cephalograms and evaluated by three orthodontists in order to determine the extent of improvement. Samples were divided into a favorable group (upper 30% of visual analogue scale [VAS] scores, n = 14) and an unfavorable group (lower 30% of VAS scores, n = 14). Skeletal and soft-tissue measurements were performed on the cephalograms and an intergroup comparison was conducted. An independent t -test revealed that the following pre-treatment values were lower in the favorable group compared to the unfavorable group: lower incisor to mandibular plane angle, lower incisor to pogonion distance, point A-nasion-point B angle, sella-nasion line (SN) to maxillary plane angle, SN to mandibular plane angle, gonial angle, and symphysis inclination. The favorable group had a larger incisor inclination to occlusal plane. Moreover, the favorable group showed larger post-treatment changes in gonial angle, B point projection, and pogonion projection than did the unfavorable group. Class II malocclusion patients with a low divergent skeletal pattern and reduced lower incisor protrusions are likely to show more improvement in soft-tissue profile outcomes following Class II Twin-block treatment.

It is uncertain whether previous ischemic stroke within 3 months of receiving intravenous thrombolysis (tPA [tissue-type plasminogen activator]) for acute ischemic stroke (AIS) is associated with an increased risk of adverse outcomes. Using administrative claims data, we identified adults with AIS who received intravenous tPA at California, New York, and Florida hospitals from 2005 to 2013. Our primary outcome was intracerebral hemorrhage, and our secondary outcomes were unfavorable discharge disposition and inpatient mortality. We used logistic regression to compare rates of outcomes in patients with and without previous ischemic stroke within 3 months of intravenous tPA for AIS. We identified 36 599 AIS patients treated with intravenous tPA, of whom 568 (1.6%) had a previous ischemic stroke in the past 3 months. Of all patients who received intravenous tPA, the rate of intracerebral hemorrhage was 4.9% (95% confidence interval [CI], 4.7%-5.1%), and death occurred in 10.7% (95% CI, 10.4%-11.0%). After adjusting for demographics, vascular risk factors, and the Elixhauser Comorbidity Index, previous ischemic stroke within 3 months of thrombolysis for AIS was not associated with an increased risk of intracerebral hemorrhage (odds ratio, 0.9; 95% CI, 0.6-1.4; P =0.62), but was associated with an increased risk of death (odds ratio, 1.5; 95% CI, 1.2-1.9; P =0.001) and unfavorable discharge disposition (odds ratio, 1.3; 95% CI, 1.0-1.7; P =0.04). Among patients who receive intravenous tPA for AIS, recent ischemic stroke is not associated with an increased risk of intracerebral hemorrhage but is associated with a higher risk of death and unfavorable discharge disposition. © 2017 American Heart Association, Inc.

Objective To study the incidence, clinical presentation and outcome of intracranial hemorrhagic complications in adult patients with community associated bacterial meningitis. Methods Nationwide prospective cohort study from all hospitals in the Netherlands, from 1 March 2006, through 31 December 2010. Results Of the 860 episodes of bacterial meningitis that were included, 24 were diagnosed with intracranial hemorrhagic complications: 8 upon presentation and 16 during clinical course. Clinical presentation between patients with or without intracranial hemorrhage was similar. Causative bacteria were Streptococcus pneumoniae in 16 patients (67%), Staphylococcus aureus in 5 (21%), Pseudomonas aeruginosa and Listeria monocytogenes both in 1 patient (4%). Occurrence of intracranial hemorrhage was associated with death (63% vs. 15%, P<0.001) and unfavorable outcome (94% vs. 34%, P<0.001). The use of anticoagulants on admission was associated with a higher incidence of intracranial hemorrhages (odds ratio 5.84, 95% confidence interval 2.17–15.76). Conclusion Intracranial hemorrhage is a rare but devastating complication in patients with community-associated bacterial meningitis. Since anticoagulant therapy use is associated with increased risk for intracranial hemorrhage, physicians may consider reversing or temporarily discontinuing anticoagulation in patients with bacterial meningitis.

Published data have shown inconsistent results about the pharmacogenetics of XRCC1 gene on clinical outcomes of advanced lung cancer patients treated with platinum-based chemotherapy. This meta-analysis aimed to summarize published findings and provide more reliable association. A total of 53 eligible studies including 7433 patients were included. Patients bearing the favorable TrpTrp and TrpArg genotypes of Arg194Trp were more likely to better response rates to platinum-based chemotherapy compared to those with the unfavorable ArgArg genotype (TrpTrp+TrpArg vs. ArgArg: odds ratio (OR) = 2.02, 95% CI, 1.66–2.45). The GlnGln and GlnArg genotypes of Arg399Gln were significantly associated with the poorer response rates compared to those with the ArgArg genotype (GlnGln +GlnArg vs. ArgArg: OR = 0.68, 95% CI, 0.54–0.86). The GlnGln genotype might be more closely associated with shorter survival time and higher risks of death for patients (GlnGln vs. ArgArg: hazard ratio (HR) = 1.14, 95% CI, 0.75–1.75). Our cumulative meta-analyses indicated a distinct apparent trend toward a better response rate for Arg194Trp, but a poorer response rate in Arg399Gln. These findings indicate a predictive role of XRCC1 polymorphisms in clinical outcomes. The use of XRCC1 polymorphisms as predictive factor of clinical outcomes in personalized chemotherapy treatment requires further verification from large well-designed pharmacogenetics studies.

To review data on malpractice claims related to refractive surgery to identify common allegations and injuries and financial outcomes. The WestlawNext database was reviewed for all malpractice lawsuits/settlements related to refractive eye surgery. Data evaluated included patient demographics, type of operation performed, plaintiff allegation, nature of injury, and litigation outcomes. A total of 167 cases met the inclusion criteria, of which 108 cases (64.7%) were found to be favorable and 59 cases (35.3%) unfavorable to the defendant. A total of 141 cases were tried by a jury with 108 cases (76.4%) favorable and 33 cases (23.6%) unfavorable to the defendant. Laser in situ keratomileusis was performed in 127 cases (76%). The most common allegations were negligence in treatment or surgery in 127 cases (76%) and lack of informed consent in 83 cases (49.7%). For all cases, the need for future surgery (P = 0.0001) and surgery resulting in keratoconus (P = 0.05) were more likely to favor the plaintiff. In jury verdict decisions, cases in which failure to diagnose a preoperative condition was alleged favored the defendant (P = 0.03), whereas machine malfunction (P = 0.05) favored the plaintiff. After adjustment for inflation, the overall mean award was $1,287,872. Jury verdicts and settlements led to mean awards of $1,604,801 and $826,883, respectively. Malpractice litigation in refractive surgery tends to favor the defendant. However, large awards and settlements were given in cases that were favorable to the plaintiff. The need for future surgery and surgery leading to keratoconus increased the chance of an unfavorable outcome.

Post traumatic hydrocephalus (PTH) is a frequent complication during rehabilitation following severe TBI. However, the diagnosis of PTH is not straightforward and despite shunting recovery may be delayed. To study the influence of PTH on recovery and outcome during rehabilitation. We studied 417 patients with severe TBI admitted consecutively to a single hospital-based neurorehabilitation department serving Eastern Denmark between 2000 and 2010. Demographics (age and gender) and clinical characteristics (length of acute treatment, post traumatic amnesia (PTA), level of consciousness, injury severity (ISS), and admission FIM™), and PTH were related to recovery (discharge FIM™), outcome (GOS), and length of rehabilitation stay. Patients with PTH were older, brain injury more severe, and acute treatment was longer. At discharge they had more disability, longer rehabilitation stays, and unfavorable outcome. However, after adjusted multiple regression analyses PTH was not associated with disability at discharge or outcome. Instead, PTH was associated with longer stay for rehabilitation. Shunting for PTH does not affect recovery and outcome per se, but prolongs lengths of stay by almost 3 weeks. Therefore, patients treated for PTH are as likely to benefit from rehabilitation as patients without, but require longer rehabilitation stays.

The Glasgow Outcome Scale (GOS) is firmly established as the primary outcome measure for use in Phase III trials of interventions in traumatic brain injury (TBI). However, the GOS has been criticized for its lack of sensitivity to detect small but clinically relevant changes in outcome. The Glasgow Outcome Scale-Extended (GOSE) potentially addresses this criticism, and in this study we estimate the efficiency gain associated with using the GOSE in place of the GOS in ordinal analysis of 6-month outcome. The study uses both simulation and the reanalysis of existing data from two completed TBI studies, one an observational cohort study and the other a randomized controlled trial. As expected, the results show that using an ordinal technique to analyze the GOS gives a substantial gain in efficiency relative to the conventional analysis, which collapses the GOS onto a binary scale (favorable versus unfavorable outcome). We also found that using the GOSE gave a modest but consistent increase in efficiency relative to the GOS in both studies, corresponding to a reduction in the required sample size of the order of 3-5%. We recommend that the GOSE be used in place of the GOS as the primary outcome measure in trials of TBI, with an appropriate ordinal approach being taken to the statistical analysis.

Timing of operation for poor-grade aneurysmal subarachnoid hemorrhage: study protocol for a randomized controlled trial

PubMed Central

2013-01-01

Background Subarachnoid hemorrhage is a common and dangerous disease with an unfavorable prognosis. Patients with poor-grade subarachnoid hemorrhage (Hunt & Hess Grades 4–5) are unconscious on admission. Because of the high mortality and disability rate associated with poor-grade subarachnoid hemorrhage, it is often treated conservatively. Timing of surgery for poor-grade aneurysmal subarachnoid hemorrhage is still controversial, therefore this study aims to identify the optimal time to operate on patients admitted in poor clinical condition. Methods/design Ninety-nine patients meeting the inclusion criteria were randomly assigned into three treatment groups. The early surgery group received operation within 3 days after onset of subarachnoid hemorrhage (day of SAH = day 1); the intermediate surgery group received operation from days 4 to 7, and surgery was performed on the late surgery group after day 7. Follow-up was performed 1, 3, and 6 months after aneurysm clipping. Primary indicators of outcome included the Extended Glasgow Outcome Scale and the Modified Rankin Scale, while secondary indicators of outcome were assessed using the Barthel Index and mortality. Discussion This is the first prospective, single-center, observer-blinded, randomized controlled trial to elucidate optimal timing for surgery in poor-grade subarachnoid hemorrhage patients. The results of this study will be used to direct decisions of surgical intervention in poor-grade subarachnoid hemorrhage, thus improving clinical outcomes for patients.

A considerable proportion of the geriatric population experiences unfavorable outcomes of hospital emergency department care. An assessment of risk for adverse outcomes would facilitate making changes in clinical management by adjusting available resources to needs according to an individual patient's risk. Risk assessment tools are available, but their prognostic precision varies. This systematic review sought to quantify the prognostic precision of 2 geriatric screening and risk assessment tools commonly used in emergency settings for patients at high risk of adverse outcomes (revisits, functional deterioration, readmissions, or death): the Identification of Seniors at Risk (ISAR) scale and the Triage Risk Screening Tool (TRST). We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and SCOPUS, with no date limits, to find relevant studies. Quality was assessed with the QUADAS-2 checklist (for quality assessment of diagnostic accuracy studies). We pooled data for prognostic yield reported for the ISAR and TRST scores for each short- and medium-term outcome using bivariate random-effects modeling. The sensitivity of the ISAR scoring system as a whole ranged between 67% and 99%; specificity fell between 21% and 41%. TRST sensitivity ranged between 52% and 75% and specificity between 39% and 51%.We conclude that the tools currently used to assess risk of adverse outcomes in patients of advanced age attended in hospital emergency departments do not have adequate prognostic precision to be clinically useful.

To examine the relationship between cigarette smoking and incidence and mortality rates of pulmonary tuberculosis (TB) and treatment outcomes. From 1995 to 2010, we analyzed data from 1062 patients with TB and from 2001 to 2004, 2951 contacts in Southern Mexico. Patients with acid-fast bacilli or Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and mycobacteriological evaluation and received treatment by the local DOTS program. Consumers of 1-10 (LS) or 11 or more (HS) cigarettes per day incidence (1.75 and 11.79) and mortality (HS, 17.74) smoker-non-smoker rate ratios were significantly higher for smokers. Smoker population was more likely to experience unfavorable treatment outcomes (HS, adjusted OR 2.36) and retreatment (LS and HS, adjusted hazard ratio (HR) 2.14 and 2.37). Contacts that smoked had a higher probability of developing active TB (HR 2.38) during follow up. Results indicate the need of incorporating smoking prevention and cessation, especially among men, into international TB control strategies. Copyright © 2012 The British Infection Association.

OBJECTIVE Obstructive sleep apnea (OSA) is associated with the progression of abdominal and thoracic aortic aneurysms. However, the role of OSA in the overall outcome of intracranial aneurysms (IAs) has not yet been established. Authors of this report investigated the role of OSA in the overall outcome of IAs. METHODS Radiological and clinical data on patients (from 2010 through 2015) with confirmed IA were retrospectively reviewed. Significant differences between the OSA and non-OSA groups were determined using a chi-square test. Logistic regression analysis was performed to identify the predictors of an unfavorable IA outcome. RESULTS Among the 283 patients with confirmed IAs, 45 patients (16%) were positively screened for OSA, a proportion that was significantly higher than the prevalence of OSA in nonaneurysmal neurosurgical patients (4%, p = 0.008). The percentage of patients with hypertension (p = 0.018), a body mass index ≥ 30 kg/m 2 (p < 0.0001), hyperlipidemia (p = 0.034), diabetes mellitus (p = 0.005), chronic heart disease (CHD; p = 0.024), or prior stroke (p = 0.03) was significantly higher in the OSA group than in the non-OSA group. Similarly, the percentage of wide-necked aneurysms (p = 0.00001) and patients with a poor Hunt and Hess Grade IV-V (p = 0.01) was significantly higher in the OSA group than in the non-OSA group. In addition, the percentage of ruptured aneurysms (p = 0.03) and vasospasms (p = 0.03) was significantly higher in the OSA group. The percentage of patients with poor modified Rankin Scale (mRS) scores (3-6) was significantly higher in the OSA group (p = 0.03). A separate cohort of patients with ruptured IAs showed similar results. In both univariate (p = 0.01) and multivariate (p = 0.04) regression analyses, OSA was identified as an individual predictor of an unfavorable outcome. In addition, hypertension and prior stroke were revealed as predictors of a poor IA outcome. CONCLUSIONS Complications of IA such as rupture and vasospasm are often the consequence of uncontrolled OSA. Overall outcome (mRS) of IAs is also affected by the co-occurrence of OSA. Therefore, the coexistence of OSA with IA affects the outcome of IAs. Obstructive sleep apnea is a risk factor for a poor outcome in IA patients.

Background Net atrioventricular compliance (Cn) has been reported to be an important determinant of pulmonary hypertension in mitral stenosis (MS). We hypothesized that, as Cn reflects hemodynamic consequences of MS, it may be useful in assessing prognosis. To date, limited data with an assumed Cn cutoff have indicated the need for larger prospective studies. This prospective study was designed to determine the impact of Cn on clinical outcome and its contribution to pulmonary pressure in MS. In addition, we aimed to identify a cutoff value of Cn for outcome prediction in this setting. Methods and Results A total of 128 patients with rheumatic MS without other significant valve disease were prospectively enrolled. Comprehensive echocardiography was performed and Doppler-derived Cn estimated using a previously validated equation. The endpoint was either mitral valve intervention or death. Cn was an important predictor of pulmonary pressure, regardless of classic measures of MS severity. During a median follow-up of 22 months, the endpoint was reached in 45 patients (35%). Baseline Cn predicted outcome, adding prognostic information beyond that provided by mitral valve area and functional status. Cn ≤ 4 mL/mmHg best predicted unfavorable outcome in derivation and validation sets. A subgroup analysis including only initially asymptomatic patients with moderate to severe MS without initial indication for intervention (40.6 % of total) demonstrated that baseline Cn predicted subsequent adverse outcome even after adjusting for classic measures of hemodynamic MS severity (hazard ratio [HR] 0.33, 95% confidence interval [CI] 0.14–0.79, p = 0.013). Conclusions Cn contributes to pulmonary hypertension beyond of stenosis severity itself. In a wide spectrum of MS severity, Cn is a powerful predictor of adverse outcome, adding prognostic value to clinical data and mitral valve area. Importantly, baseline Cn predicts a progressive course with subsequent need for intervention in initially asymptomatic patients. Cn assessment therefore has potential value for clinical risk stratification and monitoring in MS patients. PMID:24097419

An artificial system for selecting the optimal surgical team.

We introduce an intelligent system to optimize a team composition based on the team's historical outcomes and apply this system to compose a surgical team. The system relies on a record of the procedures performed in the past. The optimal team composition is the one with the lowest probability of unfavorable outcome. We use the theory of probability and the inclusion exclusion principle to model the probability of team outcome for a given composition. A probability value is assigned to each person of database and the probability of a team composition is calculated from them. The model allows to determine the probability of all possible team compositions even if there is no recoded procedure for some team compositions. From an analytical perspective, assembling an optimal team is equivalent to minimizing the overlap of team members who have a recurring tendency to be involved with procedures of unfavorable results. A conceptual example shows the accuracy of the proposed system on obtaining the optimal team.

Recently, we faced difficult treatment decisions regarding appropriate adjuvant systemic treatment, especially for patients who show discordance between stage and tumor biology. The aim of this study was to compare the prognostic relevance of the TNM staging system with that of intrinsic subtype in breast cancer. We retrospectively identified women patients who received curative surgery for stage I-III breast cancer with available data on immunohistochemistry profiles including hormone receptor (HR) status, human epidermal growth factor receptor 2 (HER2) status, and Ki 67 staining at the Samsung Medical Center from January 2004 to September 2008. Primary outcomes were recurrence-free survival (RFS) and overall survival (OS). A total of 1145 patients were diagnosed with breast cancer and received curative surgery. Of these, 463 (40.4%) patients were stage I, and 682 (59.6%) were stage II or III. In addition, 701 (61.2%) patients were HR positive, 239 (20.9%) were HER2 positive, and 205 (20.9%) had triple-negative breast cancer. The 5-year RFS for the patients who were HR positive and HER2 negative with a low Ki 67 staining score (0-25%) was 99%. The 5-year RFS for patients who were HER2-positive or had triple-negative breast cancer were 89 and 83%, respectively (P value = <0.001). In multivariate analysis, advanced stage (II/III) and unfavorable biology (HER2 positive or triple negative) retained their statistical significance as predictors of decreased RFS and OS. Patients with advanced-stage disease (II or III) but favorable tumor biology (HR positive and HER2 negative and low Ki 67) had better clinical outcomes than those with stage I disease and unfavorable tumor biology in terms of RFS (99 versus 92%, P value = 0.011) and OS (99 versus 96%, P value = 0.03) at 5 years. The current results showed that intrinsic subtype has a greater prognostic impact in predicting clinical outcomes in subpopulations of patients with stage I-III breast cancer who show discordance between stage and biologic subtypes.

This study assessed the degree to which Holocaust survivors have dealt successfully with the eight psychosocial crises thought by Erikson (1959) to mark important stages in life-span development. In Study 1, 50 autobiographical interviews of survivors videotaped 30-50 years after the war were subjected to thematic content analysis. Relevant passages were coded as representing either a favorable or an unfavorable outcome as defined by Erikson. Survivors described significantly more favorable than unfavorable outcomes for seven of the crises; the exception was Trust vs. Mistrust. In Study 2, audiotaped Holocaust survivor interviews conducted in 1946 were scored in the same way and compared with the results of Study 1. There were several significant differences as well as similarities between the two data sets, the later interviews mostly showing changes in the positive direction.

Samples were divided into a favorable group (upper 30% of visual analogue scale [VAS] scores, n = 14) and an unfavorable group (lower 30% of VAS scores, n = 14). Skeletal and soft-tissue measurements were performed on the cephalograms and an intergroup comparison was conducted. Results An independent t-test revealed that the following pre-treatment values were lower in the favorable group compared to the unfavorable group: lower incisor to mandibular plane angle, lower incisor to pogonion distance, point A-nasion-point B angle, sella-nasion line (SN) to maxillary plane angle, SN to mandibular plane angle, gonial angle, and symphysis inclination. The favorable group had a larger incisor inclination to occlusal plane. Moreover, the favorable group showed larger post-treatment changes in gonial angle, B point projection, and pogonion projection than did the unfavorable group. Conclusions Class II malocclusion patients with a low divergent skeletal pattern and reduced lower incisor protrusions are likely to show more improvement in soft-tissue profile outcomes following Class II Twin-block treatment.

Fistulas are the preferred permanent hemodialysis vascular access, but a significant obstacle to increasing their prevalence is the fistula's high "failure to mature" (FTM) rate. This study aimed to identify postoperative clinical characteristics that are predictive of fistula FTM. This descriptive cross-sectional study was performed on 80 end-stage renal disease patients who referred to Al Zahra Hospital, Isfahan, for brachiocephalic fistula placement. After 4 weeks, the clinical criteria (trill, firmness, vein length, and venous engorgement) examined and the fistulas situation divided to favorable or unfavorable by each criterion, and the results comprised with dialysis possibility. Data were analyzed with SPSS version 21. Diagnostic index for CLINICAL examination was calculated. Among the 80 cases, 25 (31.2%) female and 55 (68.8%) male were studied with the mean age of 51.9 (standard deviation = 17) year ranged between 18 and 86 years old. Sixty-two (77.5%) cases had successful hemodialysis. All four clinical assessments were significantly more acceptable in patients with successful dialysis ( P < 0.001). According to the results of our study, the accuracy of all physical assessments was above 70% and except vein length other criteria had a sensitivity and negative predictive value of 100%. In this study, firmness of vein has highest specificity and positive predictive value (83.9% and 64.3%, respectively). Results of our study showed that high sensitivity and relatively low specificity of the clinical criterion. It means that unfavorable results of each clinical criterion predict unfavorable dialysis. Clinical evaluation of a newly created fistula 4-6 weeks after surgery should be considered mandatory.

Patients with severe prune belly syndrome rarely survive beyond the first days of life. We present a case of prune belly syndrome that initially presented with severe oligohydramnios, megacystis and associated poor urine biochemistries. Due to an anteriorly located placenta the patient was referred to three major centers, but was turned down because of the unfavorable prognostic findings. Therefore, fetal intervention was performed with 32 vesicocentesis and amnioinfusion procedures. Despite the unfavorable prenatal findings, and having undergone numerous fetal interventions, the birth resulted in a viable infant.

Background Diffuse large B-cell lymphoma is a clinically and molecularly heterogeneous disease. Gene expression profiling studies have shown that the tumor microenvironment affects survival and that the angiogenesis-related signature is prognostically unfavorable. The contribution of histopathological microvessel density to survival in diffuse large B-cell lymphomas treated with immunochemotherapy remains unknown. The purpose of this study is to assess the prognostic impact of histopathological microvessel density in two independent series of patients with diffuse large B-cell lymphoma treated with immunochemotherapy. Design and Methods One hundred and forty-seven patients from the Leukemia Lymphoma Molecular Profiling Project (training series) and 118 patients from the Catalan Lymphoma-Study group-GELCAB (validation cohort) were included in the study. Microvessels were immunostained with CD31 and quantified with a computerized image analysis system. The stromal scores previously defined in 110 Leukemia Lymphoma Molecular Profiling Project cases were used to analyze correlations with microvessel density data. Results Microvessel density significantly correlated with the stromal score (r=0.3209; P<0.001). Patients with high microvessel density showed significantly poorer overall survival than those with low microvessel density both in the training series (4-year OS 54% vs. 78%; P=0.004) and in the validation cohort (57% vs. 81%; P=0.006). In multivariate analysis, in both groups high microvessel density was a statistically significant unfavorable prognostic factor independent of international prognostic index [training series: international prognostic index (relative risk 2.7; P=0.003); microvessel density (relative risk 1.96; P=0.002); validation cohort: international prognostic index (relative risk 4.74; P<0.001); microvessel density (relative risk 2.4; P=0.016)]. Conclusions These findings highlight the impact of angiogenesis in the outcome of patients with diffuse large B-cell lymphoma and the interest of evaluating antiangiogenic drugs in clinical trials.

Sarcopenia, the degenerative and systemic loss of skeletal muscle mass, develops as a consequence of the progression of cancer cachexia. Recent studies suggest that sarcopenia may be used as a biomarker in the management of patients with several cancers. Areas covered: In this article, the authors review 1) the methods to simply and optimally evaluate and define sarcopenia using computed tomography images in daily clinical practice and 2) the impact of sarcopenia in the management of urological cancers, specifically focusing on the usefulness in predicting treatment-related complications and prognosis. The authors also discuss the prognostic importance of changes in skeletal muscle mass in the course of treatment and the potential roles of nutritional support and exercise to prevent progression of sarcopenia. Expert commentary: Sarcopenia is associated with treatment-related complications and unfavorable prognosis in urological cancer patients. Nutritional support and exercise might be helpful in improving sarcopenia. The impact of these interventions on clinical outcomes would be elucidated by ongoing or future clinical studies.

[Clinical prognosis of schizophrenic patients with cannabis addiction. Between nihilism and hope].

PubMed

Schnell, T

Comorbid substance use disorders in schizophrenia are mostly associated with an unfavorable course of the disease and with difficulties in clinical management. Therefore, some therapists tend to react to these patients in a resigned manner. However, there is growing evidence for higher cognitive functioning and less severe deficits in brain morphology of these patients compared to patients without cannabis use. A common interpretation refers to relatively low vulnerability for psychosis in some of these patients, who mainly became schizophrenic because of the pro-psychotic properties of cannabis. Low vulnerability is reflected by a higher cognitive functioning; therefore, the pessimistic view of therapists seems unjustified for at least a subgroup of young patients. Provided that patients are treated in adequate therapeutic settings and that they stop using cannabis, a lower vulnerability may be associated with overall better socio-rehabilitative outcome parameters.

Adult T-cell leukemia/lymphoma (ATLL) is a fatal disease caused by human T-cell leukemia virus type 1 (HTLV-1). We retrospectively analyzed 195 patients with ATLL (lymphomatous n = 96, acute n = 80, unfavorable chronic n = 7, chronic n = 5, smoldering n = 3, and unclassified n = 4) diagnosed between 1987 and 2016 (median age 52 years, 77% Afro-Caribbean). Hypercalcemia was associated with acute ATLL (65%, vs 23% lymphomatous) (P = .012). The median survival for patients treated with modern therapies between 2000 and 2016 was 4.1 months for acute, 10.2 months for lymphomatous, 72 months for chronic/smoldering, and not reached for unfavorable chronic type, with 4-year survival rates of 10%, 4%, 60%, and 83%, respectively. The overall response rate (ORR) after first-line multiagent chemotherapy was 78% (complete response [CR] 39%) for acute vs 67% (CR 33%) for lymphomatous ATLL. First-line zidovudine interferon-α (AZT-IFN) resulted in ORR of 56% (CR 23%) for acute (n = 43), 33% (CR 16.5%) for lymphomatous (n = 6), and 86% (CR 29%) for unfavorable chronic ATLL. The median progression-free survival (PFS) in patients with aggressive ATLL who achieved CR after AZT-IFN was 48 months vs 11 months after chemotherapy (P = .003). Allogeneic hematopoietic stem cell transplant (allo-HSCT) resulted in a PFS of 24 and 28 months in 2 patients with lymphomatous ATLL. Our results suggest high-dose AZT-IFN is a reasonable up-front option for patients with aggressive leukemic ATLL followed by chemotherapy switch in nonresponders, whereas chemotherapy should be used in lymphomatous type followed by allo-HSCT when feasible.

Abstract The Glasgow Outcome Scale (GOS) is firmly established as the primary outcome measure for use in Phase III trials of interventions in traumatic brain injury (TBI). However, the GOS has been criticized for its lack of sensitivity to detect small but clinically relevant changes in outcome. The Glasgow Outcome Scale-Extended (GOSE) potentially addresses this criticism, and in this study we estimate the efficiency gain associated with using the GOSE in place of the GOS in ordinal analysis of 6-month outcome. The study uses both simulation and the reanalysis of existing data from two completed TBI studies, one an observational cohort study and the other a randomized controlled trial. As expected, the results show that using an ordinal technique to analyze the GOS gives a substantial gain in efficiency relative to the conventional analysis, which collapses the GOS onto a binary scale (favorable versus unfavorable outcome). We also found that using the GOSE gave a modest but consistent increase in efficiency relative to the GOS in both studies, corresponding to a reduction in the required sample size of the order of 3–5%. We recommend that the GOSE be used in place of the GOS as the primary outcome measure in trials of TBI, with an appropriate ordinal approach being taken to the statistical analysis. PMID:22026476

Cerebrospinal fluid (CSF) biomarkers might be useful in predicting outcome after aneurysmal subarachnoid hemorrhage (aSAH). It was the aim to determine whether tau and amyloid beta CSF concentrations predict functional, health-related quality of life (hrQoL), and neuropsychological outcomes after aSAH. Ventricular CSF was obtained from n = 24 aSAH patients at admission (D0), day 2 (D2), and day 6 (D6). CSF total (t)Tau, phosphorylated (p)Tau (181P) , and amyloid beta (1-40 and 1-42) (Aβ40/Aβ42) levels were compared between patients with favorable and unfavorable functional (modified Rankin Scale (mRS)), hrQoL (Euro-Qol (EQ-5D)), and neuropsychological outcomes at 3 (3 m) and 12 months (12 m). Patients with unfavorable functional (mRS 4-6) and hrQoL outcome (EQ-5D z-score ≤ - 1.0) at 3 and 12 m had higher CSF tTau/pTau and lower Aβ40/Aβ42 at D0, D2, and D6 with varying degrees of statistical significance. In terms of predicting neuropsychological outcome, CSF pTau showed a statistically significant correlation with the z-scores of executive function (r = - 0.7486, p = 0.008), verbal memory (r = - 0.8101, p = 0.002), attention (r = - 0.6498, p = 0.030), and visuospatial functioning (r = - 0.6944, p = 0.017) at 3 m. At 12 m, CSF pTau had statistically significant correlations with the z-scores of verbal memory (r = - 0.7473, p = 0.008) and visuospatial functioning (r = - 0.6678, p = 0.024). In conclusion, higher tTau/pTau and lower Aβ40/Aβ42 CSF levels predict unfavorable long-term functional and hrQoL outcomes. Neuropsychological deficits correlate with increased CSF tTau and pTau concentrations.

Lower Cardiac Vagal Tone in Non-Obese Healthy Men with Unfavorable Anthropometric Characteristics

OBJECTIVES: to determine if there are differences in cardiac vagal tone values in non-obese healthy, adult men with and without unfavorable anthropometric characteristics. INTRODUCTION: It is well established that obesity reduces cardiac vagal tone. However, it remains unknown if decreases in cardiac vagal tone can be observed early in non-obese healthy, adult men presenting unfavorable anthropometric characteristics. METHODS: Among 1688 individuals assessed between 2004 and 2008, we selected 118 non-obese (BMI <30 kg/m2), healthy men (no known disease conditions or regular use of relevant medications), aged between 20 and 77 years old (42 ± 12-years-old). Their evaluation included clinical examination, anthropometric assessment (body height and weight, sum of six skinfolds, waist circumference and somatotype), a 4-second exercise test to estimate cardiac vagal tone and a maximal cardiopulmonary exercise test to exclude individuals with myocardial ischemia. The same physician performed all procedures. RESULTS: A lower cardiac vagal tone was found for the individuals in the higher quintiles – unfavorable anthropometric characteristics - of BMI (p=0.005), sum of six skinfolds (p=0.037) and waist circumference (p<0.001). In addition, the more endomorphic individuals also presented a lower cardiac vagal tone (p=0.023), while an ectomorphic build was related to higher cardiac vagal tone values as estimated by the 4-second exercise test (r=0.23; p=0.017). CONCLUSIONS: Non-obese and healthy adult men with unfavorable anthropometric characteristics tend to present lower cardiac vagal tone levels. Early identification of this trend by simple protocols that are non-invasive and risk-free, using select anthropometric characteristics, may be clinically useful in a global strategy to prevent cardiovascular disease.

Cardiovascular mechanisms of SSRI drugs and their benefits and risks in ischemic heart disease and heart failure.

Depression and heart disease are commonly comorbid. Selective serotonin reuptake inhibitors (SSRIs) are commonly used to treat depression. In March 2011, we carried out a 15-year search of PubMed for preclinical and clinical publications related to SSRIs and ischemic heart disease (IHD) or congestive heart failure (CHF). We identify and discuss a number of mechanisms by which SSRIs may influence cardiovascular functioning and health outcomes in patients with heart disease; many of the mechanisms that we present have received little attention in previous reviews. We examine studies with positive, neutral, and negative outcomes in IHD and CHF patients treated with SSRIs. SSRIs influence cardiovascular functioning and health through several different mechanisms; for example, they inhibit serotonin-mediated and collagen-mediated platelet aggregation, reduce inflammatory mediator levels, and improve endothelial function. SSRIs improve indices of ventricular functioning in IHD and heart failure without adversely affecting electrocardiographic parameters. SSRIs may also be involved in favorable or unfavorable drug interactions with medications that influence cardiovascular functions. The clinical evidence suggests that, in general, SSRIs are safe in patients with IHD and may, in fact, exert a cardioprotective effect. The clinical data are less clear in patients with heart failure, and the evidence for benefits with SSRIs is weak.

Several intravascular ultrasound studies have reported that culprit lesion-attenuated plaque (AP) is related to slow flow/no reflow after percutaneous coronary intervention (PCI). Long-term prognostic impact of the AP is unknown. The aim of this study was to investigate acute and long-term clinical impact of the AP in patients with acute coronary syndrome (ACS). A total of 110 ACS patients who underwent successful PCI were enrolled. Acute and long-term clinical outcomes were compared between patients with AP (AP group: n = 73) and those without AP (non-AP group: n = 37). Long-term cardiac event was defined as a composite of death and ACS. Baseline characteristics in 2 groups were similar. AP was associated with higher TIMI frame count immediately after the first balloon inflation. After thrombectomy and intracoronary drug administration, final TIMI frame count became similar between AP and non-AP group. Although AP was associated with higher incidence of fatal arrhythmia during hospitalization, in-hospital mortality did not differ between the 2 groups. During follow-up (median 6.2 years), cardiac event-free survival did not differ between the 2 groups. Despite the initial unfavorable effect on coronary reflow, presence of AP did not affect acute as well as long-term clinical outcome in patients with ACS.

To investigate the clinical and surgical outcome correlates of preoperative hippocampal subfield volumes in patients with refractory temporal lobe epilepsy (TLE) using a new magnetic resonance imaging (MRI) multisequence segmentation technique. We recruited 106 patients with TLE and hippocampal sclerosis (HS) who underwent conventional T1-weighted and T2 short TI inversion recovery MRI. An automated hippocampal segmentation algorithm was used to identify twelve subfields in each hippocampus. A total of 76 patients underwent amygdalohippocampectomy and postoperative seizure outcome assessment using the standardized ILAE classification. Semiquantitative hippocampal internal architecture (HIA) ratings were correlated with hippocampal subfield volumes. Patients with left TLE had smaller volumes of the contralateral presubiculum and hippocampus-amygdala transition area compared to those with right TLE. Patients with right TLE had reduced contralateral hippocampal tail volumes and improved outcomes. In all patients, there were no significant relationships between hippocampal subfield volumes and clinical variables such as duration and age at onset of epilepsy. There were no significant differences in any hippocampal subfield volumes between patients who were rendered seizure free and those with persistent postoperative seizure symptoms. Ipsilateral but not contralateral HIA ratings were significantly correlated with gross hippocampal and subfield volumes. Our results suggest that ipsilateral hippocampal subfield volumes are not related to the chronicity/severity of TLE. We did not find any hippocampal subfield volume or HIA rating differences in patients with optimal and unfavorable outcomes. In patients with TLE and HS, sophisticated analysis of hippocampal architecture on MRI may have limited value for prediction of postoperative outcome. © 2018 The Authors.

Subfebrile body temperature and fever in the first days after stroke are strongly associated with unfavorable outcome. A subgroup analysis of a previous trial suggested that early treatment with paracetamol may improve functional outcome in patients with acute stroke and a body temperature of ≥36.5°C. In the present trial, we aimed to confirm this finding. PAIS 2 (Paracetamol [Acetaminophen] in Stroke 2) was a multicenter, randomized, double-blind, placebo-controlled clinical trial. We aimed to include 1500 patients with acute ischemic stroke or intracerebral hemorrhage within 12 hours of symptom onset. Patients were treated with paracetamol in a daily dose of 6 g or matching placebo for 3 consecutive days. The primary outcome was functional outcome at 3 months, assessed with the modified Rankin Scale and analyzed with multivariable ordinal logistic regression. Because of slow recruitment and lack of funding, the study was stopped prematurely. Between December 2011 and October 2015, we included 256 patients, of whom 136 (53%) were allocated to paracetamol. In this small sample, paracetamol had no effect on functional outcome (adjusted common odds ratio, 1.15; 95% confidence interval, 0.74-1.79). There was no difference in the number of serious adverse events (paracetamol n=35 [26%] versus placebo n=28 [24%]). Treatment with high-dose paracetamol seemed to be safe. The effect of high-dose paracetamol on functional outcome remains uncertain. Therefore, a large trial of early treatment with high-dose paracetamol is still needed. URL: http://www.trialregister.nl.

Globally, India has the world's highest burden of multidrug-resistant tuberculosis (MDR-TB). Programmatic Management of Drug Resistant TB (PMDT) in India began in 2007 and nationwide coverage was achieved in early 2013. Poor initial microbiological outcomes under the Revised National Tuberculosis Control Programme (RNTCP) prompted detailed analysis. This is the first study on factors significantly associated with poor outcomes in MDR-TB patients treated under the RNTCP. To evaluate initial sputum culture conversion, culture reversion and final treatment outcomes among MDR-TB patients registered in India from 2007 to early 2011 who were treated with a standard 24-month regimen under daily-observed treatment. This is a retrospective cohort study. Clinical and microbiological data were abstracted from PMDT records. Initial sputum culture conversion, culture reversion and treatment outcomes were defined by country adaptation of the standard WHO definitions (2008). Cox proportional hazards modeling with logistic regression, multinomial logistic regression and adjusted odds ratio was used to evaluate factors associated with interim and final outcomes respectively, controlling for demographic and clinical characteristics. In the cohort of 3712 MDR-TB patients, 2735 (73.6%) had initial sputum culture conversion at 100 median days (IQR 92-125), of which 506 (18.5%) had culture reversion at 279 median days (IQR 202-381). Treatment outcomes were available for 2264 (60.9%) patients while 1448 (39.0%) patients were still on treatment or yet to have a definite outcome at the time of analysis. Of 2264 patients, 781 (34.5%) had treatment success, 644 (28.4%) died, 670 (29.6%) were lost to follow up, 169 (7.5%) experienced treatment failure or were changed to XDR-TB treatment. Factors significantly associated with either culture non-conversion, culture reversion and/or unfavorable treatment outcomes were baseline BMI < 18; ≥ seven missed doses in intensive phase (IP) and continuation phase (CP); cavitary disease; prior treatment episodes characterized by re-treatment regimen taken twice, longer duration and more episodes of treatment; any weight loss during treatment; males and additional resistance to first line drugs (Ethambutol, Streptomycin). In a subgroup of 104 MDR-TB patients, 62 (59.6%) had Ofloxacin resistance among whom only 25.8% had treatment success, half of the success (54.8%) seen in Ofloxacin sensitive patients. Baseline susceptibility to Ofloxacin (HR 2.04) and Kanamycin (HR 4.55) significantly doubled and quadrupled the chances for culture conversion respectively while baseline susceptibility to Ofloxacin (AOR 0.37) also significantly reduced the odds of unfavorable treatment outcomes (p value ≤0.05) in multinomial logistic regression model. India's initial MDR-TB patients' cohort treated under the RNTCP experienced poor treatment outcomes. To address the factors associated with poor treatment outcomes revealed in our study, a systematic multi-pronged approach would be needed. A series of policies and interventions have been developed to address these factors to improve DR-TB treatment outcomes and are being scaled-up in India.

Clinical trials in Wilms tumor (WT) have resulted in overall survival rates of greater than 90%. This achievement is especially remarkable because improvements in disease-specific survival have occurred concurrently with a reduction of therapy for large patient subgroups. However, the outcomes for certain patient subgroups, including those with unfavorable histologic and molecular features, bilateral disease, and recurrent disease, remain well below the benchmark survival rate of 90%. Therapy for WT has been advanced in part by an increasingly complex risk-stratification system based on patient age; tumor stage, histology, and volume; response to chemotherapy; and loss of heterozygosity at chromosomes 1p and 16q. A consequence of this system has been the apportionment of patients into such small subgroups that only collaboration between large international WT study groups will support clinical trials that are sufficiently powered to answer challenging questions that move the field forward. This article gives an overview of the Children's Oncology Group and International Society of Pediatric Oncology approaches to WT and focuses on four subgroups (stage IV, initially inoperable, bilateral, and relapsed WT) for which international collaboration is pressing. In addition, biologic insights resulting from collaborative laboratory research are discussed. A coordinated expansion of international collaboration in both clinical trials and laboratory science will provide real opportunity to improve the treatment and outcomes for children with renal tumors on a global level. © 2015 by American Society of Clinical Oncology.

Dissociative seizures--a critical review and perspective.

Dissociative seizures are commonly recognized as both a challenging and a poorly understood condition. Though research and publication activity is high, advances in knowledge and insight seem only moderate in recent years. This review focuses on some relevant problematic issues, which might account for a still unsatisfactory research state. A general tendency to deal with dissociative seizures as an assumed disorder in its own nosological right and not as a sole symptom of an underlying psychiatric disorder is most likely one of the major roots of the problem. Unfavorable impacts of this confusion pertaining to clinical management, therapy, and outcome of dissociative seizures are discussed. An alternative point of view, based on the immanent psychiatric and psychodynamic roots of dissociative seizures, is considered. © 2013.

Treatment of heparin-induced thrombocytopenia with drotrecogin alfa (activated).

A patient was administered drotrecogin alfa (activated) in addition to the standard of care for presumed severe sepsis and circulatory shock. Heparin-induced thrombocytopenia (HIT) and hepatic and splenic thromboses complicated her clinical course. Because drotrecogin alfa (activated) treatment is associated with improvement in thrombotic manifestations and thrombocytopenia, it was continued as the sole antithrombotic agent after the HIT became apparent. This approach was chosen despite the patient's severe hepatic and renal dysfunction, which made the use of direct thrombin inhibitors unfavorable. She survived with a reasonable outcome and salvage of her limbs. Although this case suggests a potential role of drotrecogin alfa (activated) in the management of HIT, systematic evaluation of its efficacy in this situation is warranted.

Mesial temporal sclerosis (MTS) is the most common cause of drug resistant epilepsy amenable for surgical treatment and seizure control. This study analyzed the outcome of patients with MTS following anterior temporal lobectomy and amygdalohippocampectomy (ATL-AH) over 10 years and correlated the electrophysiological and radiological factors with the post operative seizure outcome. Eighty seven patients were included in the study. Sixty seven (77.2%) patients had an Engel Class 1 outcome, 9 (11.4%) had Class 2 outcome. Engel's class 1 outcome was achieved in 89.9% at 1 year, while it reduced slightly to 81.9% at 2 years and 76.2% at 5 year follow up. Seventy seven (88.5%) patients had evidence of hippocampal sclerosis on histopathology. Dual pathology was observed in 19 of 77 specimens with hippocampal sclerosis, but did not influence the outcome. Factors associated with an unfavorable outcome included male gender (p=0.04), and a higher frequency of pre-operative seizures (p=0.005), whereas the presence of febrile seizures (p=0.048) and loss of hippocampal neurons in CA4 region on histopathology (p=0.040) were associated with favorable outcome. The effect of CA4 loss on outcome is probably influenced by neuronal loss in other subfields as well since isolated CA4 loss was rare. Abnormal post operative EEG at the end of 1 week was found to be a significant factor predicting unfavorable outcome (p=0.005). On multivariate analysis, the pre-operative seizure frequency was the only significant factor affecting outcome. The present study observed excellent seizure free outcome in a carefully selected cohort of patients with MTS with refractory epilepsy. The presence of dual pathology did not influence the outcome.

We assessed the outcomes of gender-affirming surgery (GAS, or sex-reassignment surgery) 4 to 6 years after first clinical contact, and the associations between postoperative (dis)satisfaction and quality of life (QoL). Our multicenter, cross-sectional follow-up study involved persons diagnosed with gender dysphoria (DSM-IV-TR) who applied for medical interventions from 2007 until 2009. Of 546 eligible persons, 201 (37%) responded, of whom 136 had undergone GAS (genital, chest, facial, vocal cord and/or thyroid cartilage surgery). Main outcome measures were procedure performed, self-reported complications, and satisfaction with surgical outcomes (standardized questionnaires), QoL (Satisfaction With Life Scale, Subjective Happiness Scale, Cantril Ladder), gender dysphoria (Utrecht Gender Dysphoria Scale), and psychological symptoms (Symptom Checklist-90). Postoperative satisfaction was 94% to 100%, depending on the type of surgery performed. Eight (6%) of the participants reported dissatisfaction and/or regret, which was associated with preoperative psychological symptoms or self-reported surgical complications (OR = 6.07). Satisfied respondents' QoL scores were similar to reference values; dissatisfied or regretful respondents' scores were lower. Therefore, dissatisfaction after GAS may be viewed as indicator of unfavorable psychological and QoL outcomes.

OBJECTIVE Patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH) (World Federation of Neurosurgical Societies Grade IV or V) are often considered for decompressive craniectomy (DC) as a rescue therapy for refractory intracranial hypertension. The authors performed a systematic review and meta-analysis to assess the impact of DC on functional outcome and death in patients after poor-grade aSAH. METHODS A systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were identified through the Ovid Medline, Embase, Web of Science, and Cochrane Library databases from inception to October 2015. Only studies dedicated to patients with poor-grade aSAH were included. Primary outcomes were death and functional outcome assessed at any time period. Patients were grouped as having a favorable outcome (modified Rankin Scale [mRS] Scores 1-3, Glasgow Outcome Scale [GOS] Scores 4 and 5, extended Glasgow Outcome Scale [GOSE] Scores 5-8) or unfavorable outcome (mRS Scores 4-6, GOS Scores 1-3, GOSE Scores 1-4). Pooled estimates of event rates and odds ratios with 95% confidence intervals were calculated using the random-effects model. RESULTS Fifteen studies encompassing 407 patients were included in the meta-analysis (all observational cohorts). The pooled event rate for poor outcome across all studies was 61.2% (95% CI 52%-69%) and for death was 27.8% (95% CI 21%-35%) at a median of 12 months after aSAH. Primary (or early) DC resulted in a lower overall event rate for unfavorable outcome than secondary (or delayed) DC (47.5% [95% CI 31%-64%] vs 74.4% [95% CI 43%-91%], respectively). Among studies with comparison groups, there was a trend toward a reduced mortality rate 1-3 months after discharge among patients who did not undergo DC (OR 0.58 [95% CI 0.27-1.25]; p = 0.168). However, this trend was not sustained at the 1-year follow-up (OR 1.09 [95% CI 0.55-2.13]; p = 0.79). CONCLUSIONS Results of this study summarize the best evidence available in the literature for DC in patients with poor-grade aSAH. DC is associated with high rates of unfavorable outcome and death. Because of the lack of robust control groups in a majority of the studies, the effect of DC on functional outcomes versus that of other interventions for refractory intracranial hypertension is still unknown. A randomized trial is needed.

Erikson (1959) proposed a theoretical basis for healthy psychosocial development. His theory posits eight critical conflict situations throughout one's lifetime, each of which can result in a favorable or unfavorable resolution. Autobiographies, memoirs, interviews, personal diaries, and oral histories of 97 international astronauts were content analyzed to assess reported resolutions of Erikson's psychosocial crises, regardless of chronological sequence. We made comparisons across flight phases (before, during, and after), gender, nationality of home space agency, and flight duration. Astronauts reported more favorable than unfavorable outcomes across flight phases and demographic variables. Differences across demographic variables and flight phases, as well as the changes as a result of the flight are discussed.

Pallister-Hall syndrome is a complex malformation syndrome characterized by a wide range of anomalies including hypothalamic hamartoma, polydactyly, bifid epiglottis, and genitourinary abnormalities. It is usually caused by truncating frameshift/nonsense and splicing mutations in the middle third of GLI3. The clinical course ranges from mild to lethal in the neonatal period. We present the first patient with Pallister-Hall syndrome reported with total colonic aganglionosis, a rare form of Hirschsprung disease with poor long-term outcome. The patient also had an imperforate anus, which is the third individual with Pallister-Hall syndrome reported with both Hirschsprung disease and an imperforate anus. Molecular testing via amniocentesis showed an apparently de novo novel nonsense mutation c.2641 C>T (p.Gln881*). His overall medical course was difficult and was complicated by respiratory failure and pan-hypopituitarism. Invasive care was ultimately withdrawn, and the patient expired at three months of age. This patient's phenotype was complex with unusual gastrointestinal features ultimately leading to a unfavorable prognosis and outcome, highlighting the range of clinical severity in patients with Pallister-Hall syndrome. © 2015 Wiley Periodicals, Inc.

We used data from a large international database to assess the incidence and impact of extracerebral organ dysfunction on prognosis of patients admitted after cardiac arrest (CA). This was a sub-analysis of the Intensive Care Over Nations (ICON) database, which contains data from all adult patients admitted to one of 730 participating intensive care units (ICUs) in 84 countries from 8-18 May 2012, except admissions for routine postoperative surveillance. For this analysis, patients admitted after CA (defined as those with "post-anoxic coma" or "cardiac arrest" as the reason for ICU admission) were included. Data were collected daily in the ICU for a maximum of 28 days; patients were followed up for outcome data until death, hospital discharge, or a maximum of 60 days in-hospital. Favorable neurological outcome was defined as alive at hospital discharge with a last available neurological Sequential Organ Failure Assessment (SOFA) subscore of 0-2. Among the 469 patients admitted after CA, 250 (53 %) had had out-of-hospital CA; 210 (45 %) patients died in the ICU and 357 (76 %) had an unfavorable neurological outcome. Non-survivors had a higher incidence of renal (43 vs. 16 %), cardiovascular (56 vs. 45 %), and respiratory (62 vs. 48 %) failure on admission and during the ICU stay than survivors (all p < 0.05). Similar results were found for patients with unfavorable vs. favorable neurological outcomes. In multivariable analysis, independent predictors of ICU mortality were renal failure on admission, high admission Simplified Acute Physiology Score (SAPS) II, high maximum serum lactate levels within the first 24 h after ICU admission, and development of sepsis. Independent predictors of unfavorable neurological outcome were mechanical ventilation on admission, high admission SAPS II score, and neurological dysfunction on admission. In this multicenter cohort, extracerebral organ dysfunction was common in CA patients. Renal failure on admission was the only extracerebral organ dysfunction independently associated with higher ICU mortality.

In Japan, the number of patients with foreign body airway obstruction by food is rapidly increasing with the increase in the population of the elderly and a leading cause of unexpected death. This study aimed to determine the factors that influence prognosis of these patients. This is a retrospective single institutional study. A total of 155 patients were included. We collected the variables from the medical records and analyzed them to determine the factors associated with patient outcome. Patient outcomes were evaluated using cerebral performance categories (CPCs) when patients were discharged or transferred to other hospitals. A favorable outcome was defined as CPC 1 or 2, and an unfavorable outcome was defined as CPC 3, 4, or 5. A higher proportion of patients with favorable outcomes than unfavorable outcomes had a witness present at the accident scene (68.8% vs. 44.7%, P=0.0154). Patients whose foreign body were removed by a bystander at the accident scene had a significantly high rate of favorable outcome than those whose foreign body were removed by emergency medical technicians or emergency physician at the scene (73.7% vs. 31.8%, P<0.0075) and at the hospital after transfer (73.7% vs. 9.6%, P<0.0001). The presence of a witness to the aspiration and removal of the airway obstruction of patients by bystanders at the accident scene improves outcomes in patients with foreign body airway obstruction. When airway obstruction occurs, bystanders should remove foreign bodies immediately. Copyright © 2017 Elsevier Inc. All rights reserved.

We investigated the association of gene IL6 G(-174)C polymorphism and gene IL10 G(-1082)A polymorphism with coronary artery disease (CAD) in the Russian population. A total of 1145 patients with CAD diagnose on the basis of clinical studies in cardiological hospitals of Moscow, St -Petersburg, Kazan, Chelyabinsk, Perm, Stavropol and Rostov-on-Don. Supervision term was 9.10 +/- 5.03 months (the maximum term 18 months). In case of gene IL10 G(-1082)A polymorphism we determined that patients with CAD diagnose and A alleles gene IL10 had unfavorable outcome more often than patients with homozygous G alleles. Survival time from end point from carrier genotype GA and AA is 11.68 +/- 0.67 months against 12.69 +/- 0.65 months from carrier phenotype GG gene IL10 (chi2 = 4.13, p = 0.042). The group studied do not differ significantly with respect to the distributions of gene IL6 G(-174)C alleles and genotypes. However in case combined group studies of gene IL10 G(-1082)A polymorphism and IL6 G(-174)C polymorphism we determined that patients with CAD diagnose and carrier genotype GG gene IL6 and genotype GA and AA gene IL10 had unfavorable outcome more often (survival time 11.01 +/- 1.24 months) than patients with genotype CC and CG gene IL6 and genotype GG gene IL10 (survival time 13.28 +/- 0.83 months) chi2 = 10.23, p = 0.017. The obtained data allows assuming the important role of the IL6 and IL10 genes which are responsible for functioning of inflammation system, in the accelerated formation of failures at the patients who had a coronary syndrome.

Objective: To summarize our experience with the surgical treatment of traumatic multiple intracranial hematomas (TMIHs) and discuss the surgical indications. Methods: We analyzed the clinical data of 118 patients with TMIHs who were treated at the West China Hospital in Sichuan University, Chengdu, China between October 2008 and October 2011, including age, gender, cause of injury, diagnosis, treatment, and outcomes. Results: Among the 118 patients, there were 12 patients with different types of hematomas at the same site, 69 with one hematoma type in different compartments, and 37 with different types of hematomas in different compartments. In total, 106 patients had obliteration of basal cisterns, and 34 had a simultaneous midline shift ≥5 mm. Eighty-nine patients underwent single-site surgery, 19 had 2-site surgeries, and 10 patients did not undergo surgery. Based on the Glasgow Outcome Scale 6 months post-injury, 41 patients had favorable outcomes, and 77 had unfavorable outcomes. Basal cisterns obliteration was a strong indicator for surgical treatment. Single- or 2-site surgery was not related to outcome (p=0.234). Conclusion: Obliteration of the basal cisterns is a strong indication for surgical treatment of TMIHs. After evacuation of the major hematomas, the remaining hematomas can be treated conservatively. Most patients only require single-site surgical treatment. PMID:25274591

RAC1b is a hyperactive variant of the small GTPase RAC1 known to be a relevant molecular player in different cancers. Previous studies from our group lead to the evidence that its overexpression in papillary thyroid carcinoma (PTC) is associated with an unfavorable prognosis. In the present study, we intended to extend the analysis of RAC1b expression to thyroid follicular neoplasms and to seek for clinical correlations. RAC1b expression levels were determined by RT-qPCR in thyroid follicular tumor samples comprising 23 follicular thyroid carcinomas (FTCs) and 33 follicular thyroid adenomas (FTAs). RAC1b was found to be overexpressed in 33% of carcinomas while no RAC1b overexpression was documented among follicular adenomas. Patients with a diagnosis of FTC were divided into two groups based on longitudinal evolution and final outcome. RAC1b overexpression was significantly associated with both the presence of distant metastases (P = 0.01) and poorer clinical outcome (P = 0.01) suggesting that, similarly to that previously found in PTCs, RAC1b overexpression in FTCs is also associated with worse outcomes. Furthermore, the absence of RAC1b overexpression in follicular adenomas hints its potential as a molecular marker likely to contribute, in conjunction with other putative markers, to the preoperative differential diagnosis of thyroid follicular lesions.

The number of long-term survivors of high-risk neuroblastoma remains discouraging, with 10-year survival as low as 20%, despite decades of considerable international efforts to improve outcome. Major obstacles remain and include managing resistance to induction therapy, which causes tumor progression and early death in high-risk patients, and managing chemotherapy-resistant relapses, which can occur years after the initial diagnosis. Identifying and validating novel therapeutic targets is essential to improve treatment. Delineating and deciphering specific functions of single histone deacetylases in neuroblastoma may support development of targeted acetylome-modifying therapeutics for patients with molecularly defined high-risk neuroblastoma profiles. We show here that HDAC11 depletion in MYCN-driven neuroblastoma cell lines strongly induces cell death, mostly mediated by apoptotic programs. Genes necessary for mitotic cell cycle progression and cell division were most prominently enriched in at least two of three time points in whole-genome expression data combined from two cell systems, and all nine genes in these functional categories were strongly repressed, including CENPA, KIF14, KIF23 and RACGAP1. Enforced expression of one selected candidate, RACGAP1, partially rescued the induction of apoptosis caused by HDAC11 depletion. High-level expression of all nine genes in primary neuroblastomas significantly correlated with unfavorable overall and event-free survival in patients, suggesting a role in mediating the more aggressive biological and clinical phenotype of these tumors. Our study identified a group of cell cycle-promoting genes regulated by HDAC11, being both predictors of unfavorable patient outcome and essential for tumor cell viability. The data indicate a significant role of HDAC11 for mitotic cell cycle progression and survival of MYCN-amplified neuroblastoma cells, and suggests that HDAC11 could be a valuable drug target.

Osteochondral lesions (OCLs) associated with ankle fracture correlate with unfavorable outcome. The goals of this study were to detect OCLs following ankle fracture, to associate fracture type to OCLs and to investigate whether OCLs affect clinical outcome. 100 ankle fractures requiring operative treatment were prospectively included (46 men, 54 women; mean age 44 ± 14 years, range 20-77). All ankle fractures (conventional radiography; 71 Weber B, 22 Weber C, 1 Weber A, 4 isolated medial malleolus and 2 isolated posterior malleolus fractures) were treated by open reduction and internal fixation. Multidetector computed tomography (CT) was performed postoperatively. For each OCL, the location, size, and Loomer OCL classification (CT modified Berndt and Harty classification) were determined. The subjective Foot and Ankle Outcome Scoring (FAOS) was used for clinical outcome at 1 year. OCLs were found in 10/100 ankle fractures (10.0%). All OCLs were solitary talar lesions. Four OCLs were located posteromedial, 4 posterolateral, 1 anterolateral, and 1 anteromedial. There were 2 type I OCLs (subchondral compression), 6 type II OCLs (partial, nondisplaced fracture) and 2 type IV OCLs (displaced fracture). Mean OCL size (largest diameter) was 4.4 ± 1.7 mm (range, 1.7 mm to 6.2 mm). Chi-square analysis showed no significant association between ankle fracture type and occurrence of OCLs. OCLs did occur only in Lauge-Hansen stage III/IV ankle fractures. There were no significant differences in FAOS outcome between patients with or without OCLs. Ten percent of investigated ankle fractures had associated OCLs on CT. Although no significant association between fracture type and OCL was found, OCLs only occurred in Lauge-Hansen stage III/IV ankle fractures. With the numbers available, OCLs did not significantly affect clinical outcome at 1 year according to FAOS. Level IV, observational study. © The Author(s) 2016.

To assess significance of urinary neutrophil gelatinase-associated lipocalin (NGAL) for predicting hospital complications in subjects with ischemic heart disease (IHD) after coronary artery bypass grafting (CABG). The study included 720 subjects who underwent CABG between 03/2011 and 04/2012. Blood serum creatinine level, glomerular filtration rate (GFR) (MDRD formula) and NGAL concentration were measured before and on day 7 after CABG. The following unfavorable outcomes of operative intervention: myocardial infarction (MI), stroke or transient ischemic attack, acute or progression of chronic renal disease, remediastinotomy were registered during in-hospital period. Additive EuroSCORE was calculated for all patients. There were no significant differences in serum creatinine level and GFR both before and on day 7 after CABG between groups of patients with different risk assessed by EuroSCORE, and with complicated and uncomplicated postoperative course. Urine NGAL level before and on day 7 after CABG was significantly higher in high and medium compared with low EuroSCORE risk groups. Preoperative NGAL urine level was significantly higher in patients with than in those without MI or stroke after CABG. NGAL urine level was also higher in patients with development of acute renal failure (ARF) compared with those without ARF. Both pre- and postoperative NGAL urine levels were higher in patients with unfavorable outcome while there were no significant differences in serum creatinine levels and CRF between patients with favorable and unfavorable outcomes. Preoperative measurement of urinary NGAL - a preclinical marker of acute kidney injury - allowed to predict more accurately the hospital risk of development of adverse cardiovascular and renal complications of CABG.

This study examined outcomes in elderly TBI patients who underwent a cranial operation. We identified TBI patients > or = 65 who underwent a cranial operation from January 1, 2004 to December 31, 2008. Data collected included: age, admission GCS, mechanism of injury, ISS, Head AIS, type of operation, hemorrhage acuity, time to operation, pre-hospital warfarin or clopidogrel, and in-hospital death. Survivors were contacted by phone to determine an Extended Glasgow Outcome Score (GOSE). A favorable outcome was defined as having a GOSE of > or = 5 at follow-up, an unfavorable outcome was defined as: in-hospital death, death within one year of injury, and a GOSE < 5 at follow-up. Chi-square and student's t-test were used. One hundred sixty-four elderly TBI patients underwent cranial surgery. Mean age was 79.2 +/- 7.6 years. Most patients: had a ground level fall (86.0%), suffered a subdural hematoma (95.1%), and underwent craniotomy (89.0%). Twenty-eight percent died in the hospital and another 20.1% died within one year. Fifty-six patients were eligible for a GOSE interview of these: 17 were lost to follow-up, seven refused the GOSE interview, 22 had a GOSE > or = 5, and ten had a GOSE < 5. Mean follow-up was 42.6 +/- 14.9 months. Of all the factors analyzed, only older age was associated with an unfavorable outcome. While age was associated with outcome, we were unable to demonstrate any other early factors that were associated with long-term functional outcome in elderly patients that underwent a cranial operation for TBI.

The technical evolution of endografts for the interventional management of infrarenal abdominal aortic aneurysms (AAA) has allowed a continuous expansion of indications. This study compares the established Talent endograft with its successor, the Endurant endograft, taking individual aortoiliac anatomy into account. From June 2007 to December 2010, 35 patients with AAA were treated with a Talent endograft (33 men) and 36 patients with an Endurant endograft (34 men). Aortoiliac anatomy was evaluated in detail using preinterventional computed tomography angiography. The 30-day outcome of both groups were compared regarding technical and clinical success as well as complications including endoleaks. The Endurant group included more patients with unfavorable anatomy (kinking of pelvic arteries, p = 0.017; shorter proximal neck, p = 0.084). Primary technical success was 91.4% in the Talent group and 100% in the Endurant group (p = 0.115). Type 1 endoleaks occurred in 5.7% of patients in the Talent group and in 2.8% of those in the Endurant group (p = 0.614). Type 3 endoleaks only occurred in the Talent group (2.9% of patients; p = 0.493). Type 2 endoleaks were significantly less common in the Endurant group than in the Talent group (8.3% versus 28.6%; p = 0.035). Rates of major and minor complications were not significantly different between both groups. Primary clinical success was significantly better in the Endurant group (97.2%) than in the Talent group (80.0%) (p = 0.028). Endurant endografts appear to have better technical and clinical outcome in patients with difficult aortoiliac anatomy, significantly reducing the occurrence of type 2 endoleaks.

Introduction Nonconvulsive seizures (NCS) are frequent in hospitalized patients and may further aggravate injury in the already damaged brain, potentially worsening outcomes in encephalopathic patients. Therefore, both early seizure recognition and treatment have been advocated to prevent further neurological damage. Objective Evaluate the main EEG patterns seen in patients with impaired consciousness and address the effect of treatment with antiepileptic drugs (AEDs), continuous intravenous anesthetic drugs (IVADs), or the combination of both, on outcomes. Methods This was a single center retrospective cohort study conducted in a private, tertiary care hospital. Consecutive adult patients with altered consciousness submitted to a routine EEG between January 2008 and February 2011 were included in this study. Based on EEG pattern, patients were assigned to one of three groups: Group Interictal Patterns (IP; EEG showing only interictal epileptiform discharges or triphasic waves), Group Rhythmic and Periodic Patterns (RPP; at least one EEG with rhythmic or periodic patterns), and Group Ictal (Ictal; at least one EEG showing ictal pattern). Groups were compared in terms of administered antiepileptic treatment and frequency of unfavorable outcomes (modified Rankin scale ≥3 and in-hospital mortality). Results Two hundred and six patients (475 EEGs) were included in this analysis. Interictal pattern was observed in 35.4% (73/206) of patients, RPP in 53.4% (110/206) and ictal in 11.2% (23/206) of patients. Treatment with AEDs, IVADs or a combination of both was administered in half of the patients. While all Ictal group patients received treatment (AEDs or IVADs), only 24/73 (32.9%) IP group patients and 55/108 (50.9%) RPP group patients were treated (p<0.001). Hospital length of stay (LOS) and frequency of unfavorable outcomes did not differ among the groups. In-hospital mortality was higher in IVADs treated RPP patients compared to AEDs treated RPP patients [11/19 (57.9%) vs. 11/36 (30.6%) patients, respectively, p = 0.049]. Hospital LOS, in-hospital mortality and frequency of unfavorable outcomes did not differ between Ictal patients treated exclusively with AEDs or IVADs. Conclusion In patients with acute altered consciousness and abnormal routine EEG, antiepileptic treatment did not improve outcomes regardless of the presence of periodic, rhythmic or ictal EEG patterns.

To assess the incidence and the prognostic value of acute postoperative seizures (APOS) in patients surgically treated for drug-resistant temporal lobe epilepsy due to hippocampal sclerosis (TLE-HS). We studied 139 consecutive patients with TLE-HS who underwent epilepsy surgery and were followed up for at least 5 years (mean duration of follow-up 9.1 years, range 5-15). Medical charts were reviewed to identify APOS, defined as ictal events with the exception of auras occurring within the first 7 days after surgery. Seizure outcome was determined at annual intervals. Patients who were in Engel Class Ia at the last contact were classified as having a favorable outcome. Seizure outcome was favorable in 99 patients (71%). Six patients (4%) experienced APOS and in all cases their clinical manifestations were similar to the habitual preoperative seizures. All patients with APOS had unfavorable long-term outcome, as compared with 35 (26%) of 133 in whom APOS did not occur (p<0.001). Our study suggests that APOS, despite being relatively uncommon in patients undergoing resective surgery for TLE-HS, are associated with a worse long-term seizure outcome. Given some study limitations, our findings should be regarded as preliminary and need confirmation from future larger, prospective, multicenter studies. Copyright © 2014 British Epilepsy Association.

Analyze the profile and outcome of children with rhabdomyosarcoma from a pediatric-oncology unit. Retrospective analysis of case records over 23 years (1990-2012). Government-run, tertiary-care, university hospital in Northern India. 159 children (<12-years) with a diagnosis of rhabdomyosarcoma were enrolled. The median age was 4 years; 13% were infants. Five-year event free survival. The median symptom interval was 2-months. Head and neck region was the most frequent site (44%), followed by tumors in the extremity (15.7%). The majority (67%) of the tumors were located at 'unfavorable' sites; 68% were >5 cm in size. The most frequent (58%) pathological subtype was embryonal. Treatment was based on the 'Intergroup Rhabdomyosarcoma Study (IRS) Group' risk-stratification. 33% were 'low-risk' children, 11% were 'high-risk'. Treatment-refusal (18%) and abandonment (33%) were major impediments. The median ± SE five-year event free survival of those taking treatment was 43.6 ± 6%. Large sized tumors, tumors at unfavorable locations, and treatment refusal/abandonment contributed to inferior outcome in children with rhabdomyosarcoma.

The incorporation of various novel therapies has resulted in a significant survival benefit in newly diagnosed and relapsed patients with multiple myeloma (MM) over the past decade. Despite these advances, resistance to therapy leads to eventual relapse and fatal outcomes in the vast majority of patients. Hence, there is an unmet need for new safe and efficacious therapies for continued improvement in outcomes. Given the role of epigenetic aberrations in the pathogenesis and progression of MM and the success of histone deacetylase inhibitors (HDACi) in other malignancies, many HDACi have been tried in MM. Various preclinical studies helped us to understand the antimyeloma activity of different HDACi in MM as a single agent or in combination with conventional, novel, and immune therapies. The early clinical trials of HDACi depicted only modest single-agent activity, but recent studies have revealed encouraging clinical response rates in combination with other antimyeloma agents, especially proteasome inhibitors. This led to the approval of the combination of panobinostat and bortezomib for the treatment of relapsed/refractory MM patients with two prior lines of treatment by the US Food and Drug Administration. However, it remains yet to be defined how we can incorporate HDACi in the current therapeutic paradigms for MM that will help to achieve longer disease control and significant survival benefits. In addition, isoform-selective and/or class-selective HDAC inhibition to reduce unfavorable side effects needs further evaluation. PMID:27226735

The timely detection of neurologic deterioration can be critical for the survival of a neurosurgical patient following head injury. Because little reliable evidence is available on the prognostic value of the clinical sign "extensor response" in comatose posttraumatic patients, we investigated the correlation of this clinical sign with outcome and with early radiologic findings from magnetic resonance imaging (MRI). This retrospective analysis of prospectively obtained data included 157 patients who had remained in a coma for a minimum of 24 hours after traumatic brain injury. All patients received a 1.5-T MRI within 10 days (median: 2 days) of the injury. The correlations between clinical findings 12 and 24 hours after the injury-in particular, extensor response and pupillary function, MRI findings, and outcome after 1 year-were investigated. Statistical analysis included contingency tables, Fisher exact test, odds ratios (ORs) with confidence intervals (CIs), and weighted κ values. There were 48 patients with extensor response within the first 24 hours after the injury. Patients with extensor response (World Federation of Neurosurgical Societies coma grade III) statistically were significantly more likely to harbor MRI lesions in the brainstem when compared with patients in a coma who had no further deficiencies (coma grade I; p = 0.0004 by Fisher exact test, OR 10.8 with 95% CI, 2.7-42.5) and patients with unilateral loss of pupil function (coma grade II; p = 0.0187, OR 2.8 with 95% CI, 1.2-6.5). The correlation of brainstem lesions as found by MRI and outcome according to the Glasgow Outcome Scale after 1 year was also highly significant (p ≤ 0.016). The correlation of extensor response and loss of pupil function with an unfavorable outcome and with brainstem lesions revealed by MRI is highly significant. Their sudden onset may be associated with the sudden onset of brainstem dysfunction and should therefore be regarded as one of the most fundamental warning signs in the clinical monitoring of comatose patients.

Extensive stromal interaction is one reason for the dismal outcome of biliary tract cancer (BTC) patients. Epithelial to mesenchymal transition (EMT) is involved in tumor invasion and metastasis and is partly regulated by microRNAs (miRs). This study explores the expression of anti-EMT miR200 family (miR141, −200a/b/c, −429) and miR205 as well as the EMT-related proteins E-cadherin and vimentin in a panel of BTC cell lines and clinical specimens by quantitative real-time polymerase chain reaction, Western blot and immunohistochemistry, respectively. MicroRNA expression was correlated to (i) the expression patterns of E-cadherin and vimentin; (ii) clinicopathological characteristics; and (iii) survival data. MicroRNA-200 family and miR205 were expressed in all BTC cells and clinical specimens. E-cadherin and vimentin showed a mutually exclusive expression pattern in both, in vitro and in vivo. Expression of miR200 family members positively correlated with E-cadherin and negatively with vimentin expression in BTC cells and specimens. High expression of miR200 family members (but not miR205) and E-cadherin was associated with longer survival, while low miR200 family and high vimentin expression was a predictor of unfavorable survival. Overall, the current study demonstrates the relevance of the miR200 family in EMT of BTC tumors and suggests these miRs as predictors for positive outcome. PMID:27941621

Paranoid schizophrenia with long-term course is a challenge for the clinical and therapeutic research, particularly because chronic course is difficult to identify due to the high rate of mortality in this category of patients. The therapeutic stability on an antipsychotic molecule (haloperidol) is indeed an exception, since the current trend in the case of unfavorable course is based on therapeutic versatility and polypharmacy. Haloperidol is the first-generation antipsychotic that is referred in the therapeutic guidelines as the "golden standard" regarding its efficacy on positive symptoms. The research in fundamental and molecular psychopharmacology has shown the aggressivity of this molecule on the secondary and tertiary signaling chains, including mitochondrial alterations. On male patients with paranoid schizophrenia (positive symptoms) and a chronic course of more than 35 years who received exclusively haloperidol, our study demonstrated an negative outcome with the loss of social functioning, persistence of positive symptoms, chronic extrapyramidal symptoms and mild cognitive impairment. The neuroimaging evaluations have shown atrophy in the temporal poles, posterior ventriculomegaly, cerebellar atrophy and calcification on choroid plexus and pineal gland. The difference between the histological changes induced by haloperidol on animal model and the ones on the patients in our study is located in the frontal cortex, thus suggesting the presence of two neurobiological models of schizophrenia in men: fronto-striatal and temporal-limbic-striatal. The persistence of extrapyramidal symptoms during the treatment with haloperidol may be considered as a clinical marker of the risk for negative outcome and a potential indication for the therapeutic switch.

The literature is controversial on whether intraventricular bleeding has a negative impact on the prognosis of spontaneous intracerebral hemorrhage. Nevertheless, an association between intraventricular bleeding and spontaneous intracerebral hemorrhage volumes has been consistently reported. To evaluate the prognostic value of intraventricular bleeding in deep intraparenchymal hypertensive spontaneous hemorrhage with a bleeding volume <30 cm(3). Of the 320 patients initially evaluated, 33 met the inclusion criteria and were enrolled in this prospective study. The volume of intraparenchymal hemorrhage was calculated by brain computed tomography (CT) image analysis, and the volume of intraventricular bleeding was calculated by the LeRoux scale. Clinical data, including neurological complications, were collected daily during hospitalization. Neurological outcome was evaluated 30 days after the event by using the Glasgow outcome scale. Patients were assigned to 1 of 3 groups according to intraventricular bleeding: Control, no intraventricular bleeding; LR 1, intraventricular bleeding with LeRoux scale scores of 1 to 8; or LR 2, intraventricular bleeding with LeRoux scale scores >8. There were no significant differences among groups concerning age, mean blood pressure, and time from onset to brain CT scan. Patients with greater intraventricular bleeding presented lower initial Glasgow coma scale scores, increased ventricular index and width of temporal horns, increased number of clinical and neurological complications, and longer hospitalization. Furthermore, their relative risk for unfavorable clinical outcome was 1.9 (95% confidence interval 1.25-2.49). Intraventricular bleeding with a LeRoux scale score >8 appears to have a negative effect on deep spontaneous intraparenchymal cerebral hemorrhage of small volume.

We examined the effects of fit between leader consideration and initiating structure needed and received on employees' work-related attitudes (i.e., trust in the supervisor, job satisfaction, and affective commitment to the organization). Consistent with predictions that derive from the person-environment fit research tradition, results from Study 1 suggested that deficient amounts of both leadership behaviors were associated with unfavorable attitudinal outcomes. However, while excess levels of consideration were associated with favorable attitudinal outcomes, excess levels of initiating structure were associated with unfavorable attitudes, and for both forms of leadership, higher levels of absolute fit were associated with more favorable outcomes. Results from Study 2 suggested that attitudes generated by the fit between leadership needed and received influence employees' organizational citizenship behavior as reported by their supervisors. The relationship between consideration needed and received and subordinates' organizational citizenship behavior relating to individuals (OCBI) and organizational citizenship behavior relating to the organization itself (OCBO) was partially mediated by employees' trust in the supervisor, while the relationship between initiating structure needed and received and OCBI was fully mediated by trust in the supervisor, and for OCBO was partially mediated.

Combined treatment with headgear and the Frog appliance for maxillary molar distalization: a randomized controlled trial

PubMed Central

2013-01-01

Objective To evaluate the efficiency of the Frog appliance (FA) alone or in combination with headgear for distalizing the maxillary molars. Methods Fifty patients (25 males and 25 females) aged 12.6 - 16.7 years who received treatment for Class II malocclusion at the Orthodontic Clinic of Al-Baath University were selected for this study and randomly divided into 2 equal groups. Maxillary molar distalization was achieved using the FA alone (group 1) or a combination of the FA with high-pull headgear worn at night (group 2). Lateral cephalograms were obtained before and after treatment. Results The maxillary molars moved distally by 5.51 and 5.93 mm in groups 1 and 2, respectively. Distal movements were associated with axial tipping by 4.96° and 1.25°, and with loss of anchorage by mesial movement of the second maxillary premolars by 2.70 and 0.90 mm in groups 1 and 2, respectively. The combined use of the FA and nighttime high-pull headgear decreased the distalization time and improved the ratio of maxillary molar distalization movement relative to the overall opening space between the first maxillary molars and second premolars. Conclusions The FA can effectively distalize the maxillary molars, this distalization associates with some unfavorable changes. Nighttime use of high-pull headgear combined with the FA can reduce these unfavorable changes and improve treatment outcomes. PMID:23671835

The aim of this study was to conduct comparative analyses of the biological malignant potential of clinical stage IA adenocarcinoma using positron emission tomography/computed tomography (PET/CT), high-resolution CT (HRCT), and three-dimensional CT (3DCT). The predictive performance of these parameters was evaluated in terms of clinical outcomes and pathological invasiveness (positive lymphatic permeation, blood-vessel invasion, pleural invasion, and lymph-node metastasis). We enrolled 170 patients with c-IA adenocarcinoma who underwent PET/CT, HRCT, and 3D reconstruction of lung structures using the Synapse Vincent system (Fujifilm Corporation, Tokyo, Japan) followed by complete resection. Maximum standardized uptake values (SUV max ) of F 18 -fluorodeoxyglucose and the size and volume of the solid part of the tumor were quantified and analyzed in relation to surgical outcomes. Univariate analysis demonstrated that all the three parameters and whole-tumor volume were associated with unfavorable disease-free survival (DFS), while the volume of the solid part was the independent predictor on multivariate analysis (p < .001). The receiver operating characteristic curves for pathological invasiveness, determined using the variables dichotomized at each cut-off level (SUV max 2.4; solid-part size 1.23 cm; solid-part volume 779 mm 3 ), showed that all were significantly correlated with pathological invasiveness and prognosis, whereas the combination of SUV max and the solid-part volume was the most powerful predictor of survival and pathological invasiveness compared to any other parameters: the 4-year DFS and proportion of pathological invasiveness in patients with SUV max  > 2.4 and solid-part volume > 779 mm 3 versus those with SUV max  ≤ 2.4 or solid-part volume ≤779 mm 3 were 81.2% versus 98.3% (p < .001) and 84.3% versus 15.1% (p < .001), respectively. In c-IA adenocarcinoma, the volume of the solid part of the tumor was the independent predictor for unfavorable DFS, and the integration of the volume of the solid part and SUV max was highly beneficial for the prediction of survival and pathological invasiveness.

Purpose: In the United States, early-stage Hodgkin's lymphoma (HL) is defined as asymptomatic stage I/II non-bulky disease. European groups stratify patients to more intense treatment by considering additional unfavorable factors, such as age, number of nodal sites, sedimentation rate, extranodal disease, and elements of the international prognostic score for advanced HL. We sought to determine the prognostic significance of these factors in patients with early-stage disease treated at Stanford University Medical Center. Methods and Materials: This study was a retrospective analysis of 101 patients treated with abbreviated Stanford V chemotherapy (8 weeks) and 30-Gy (n = 84 patients) or 20-Gymore » (n = 17 patients) radiotherapy to involved sites. Outcomes were assessed after applying European risk factors. Results: At a median follow-up of 8.5 years, freedom from progression (FFP) and overall survival (OS) rates were 94% and 97%, respectively. From 33% to 60% of our patients were unfavorable per European criteria (i.e., German Hodgkin Study Group [GHSG], n = 55%; European Organization for Research and Treatment of Cancer, n = 33%; and Groupe d'Etudes des Lymphomes de l'Adulte, n = 61%). Differences in FFP rates between favorable and unfavorable patients were significant only for GHSG criteria (p = 0.02) with there were no differences in OS rates for any criteria. Five of 6 patients who relapsed were successfully salvaged. Conclusions: The majority of our patients deemed unfavorable had an excellent outcome despite undergoing a significantly abbreviated regimen. Application of factors used by the GHSG defined a less favorable subset for FFP but with no impact on OS. As therapy for early-stage disease moves to further reductions in therapy, these factors take on added importance in the interpretation of current trial results and design of future studies.« less

Yes-associated protein (YAP) in pancreatic cancer: at the epicenter of a targetable signaling network associated with patient survival.

Pancreatic ductal adenocarcinoma (PDAC) is generally a fatal disease with no efficacious treatment modalities. Elucidation of signaling mechanisms that will lead to the identification of novel targets for therapy and chemoprevention is urgently needed. Here, we review the role of Yes-associated protein (YAP) and WW-domain-containing Transcriptional co-Activator with a PDZ-binding motif (TAZ) in the development of PDAC. These oncogenic proteins are at the center of a signaling network that involves multiple upstream signals and downstream YAP-regulated genes. We also discuss the clinical significance of the YAP signaling network in PDAC using a recently published interactive open-access database (www.proteinatlas.org/pathology) that allows genome-wide exploration of the impact of individual proteins on survival outcomes. Multiple YAP/TEAD-regulated genes, including AJUBA , ANLN , AREG , ARHGAP29 , AURKA , BUB1 , CCND1 , CDK6, CXCL5 , EDN2 , DKK1 , FOSL1,FOXM1 , HBEGF , IGFBP2 , JAG1 , NOTCH2 , RHAMM , RRM2 , SERP1 , and ZWILCH , are associated with unfavorable survival of PDAC patients. Similarly, components of AP-1 that synergize with YAP ( FOSL1 ), growth factors (TGFα, EPEG, and HBEGF), a specific integrin ( ITGA2 ), heptahelical receptors ( P2Y 2 R , GPR87 ) and an inhibitor of the Hippo pathway ( MUC1 ), all of which stimulate YAP activity, are associated with unfavorable survival of PDAC patients. By contrast, YAP inhibitory pathways (STRAD/LKB-1/AMPK, PKA/LATS, and TSC/mTORC1) indicate a favorable prognosis. These associations emphasize that the YAP signaling network correlates with poor survival of pancreatic cancer patients. We conclude that the YAP pathway is a major determinant of clinical aggressiveness in PDAC patients and a target for therapeutic and preventive strategies in this disease.

Dysregulation of microRNA contributes to the high incidence and mortality of breast cancer. Here, we show that miR-625 was frequently down-regulated in breast cancer. Decrease of miR-625 was closely associated with estrogen receptor (P = 0.004), human epidermal growth factor receptor 2 (P = 0.003) and clinical stage (P = 0.001). Kaplan–Meier and multivariate analyses indicated miR-625 as an independent factor for unfavorable prognosis (hazard ratio = 2.654, 95% confident interval: 1.300–5.382, P = 0.007). Re-expression of miR-625 impeded, whereas knockdown of miR-625 enhanced cell viabilities and migration abilities in breast cancer cells. HMGA1 was confirmed as a direct target of miR-625. The expressions of HMGA1 mRNA and protein weremore » induced by miR-625 mimics, but reduced by miR-625 inhibitor. Re-introduction of HMGA1 in cells expressing miR-625 distinctly abrogated miR-625-mediated inhibition of cell growth. Taken together, our data demonstrate that miR-625 suppresses cell proliferation and migration by targeting HMGA1 and suggest miR-625 as a promising prognostic biomarker and a potential therapeutic target for breast cancer. - Highlights: • miR-625 expression was significantly decreased in breast cancer. • Decrease of miR-625 was associated with poor clinical outcomes and unfavorable overall survival. • miR-625 overexpression inhibits cell proliferation and migration in vitro. • miR-625 directly targets and suppresses the expression of HMGA1.« less

We recently showed that the addition of fractionated doses of gemtuzumab ozogamicin (GO) to standard chemotherapy improves clinical outcome of acute myeloid leukemia (AML) patients. In the present study, we performed mutational analysis of 11 genes (FLT3, NPM1, CEBPA, MLL, WT1, IDH1/2, RUNX1, ASXL1, TET2, DNMT3A), EVI1 overexpression screening, and 6.0 single-nucleotide polymorphism array (SNP-A) analysis in diagnostic samples of the 278 AML patients enrolled in the ALFA-0701 trial. In cytogenetically normal (CN) AML (n = 146), 38% of the patients had at least 1 SNP-A lesion and 89% of the patients had at least 1 molecular alteration. In multivariate analysis, the independent predictors of higher cumulative incidence of relapse were unfavorable karyotype (P = 0.013) and randomization in the control arm (P = 0.007) in the whole cohort, and MLL partial tandem duplications (P = 0.014) and DNMT3A mutations (P = 0.010) in CN-AML. The independent predictors of shorter overall survival (OS) were unfavorable karyotype (P < 0.001) and SNP-A lesion(s) (P = 0.001) in the whole cohort, and SNP-A lesion(s) (P = 0.006), DNMT3A mutations (P = 0.042) and randomization in the control arm (P = 0.043) in CN-AML. Interestingly, CN-AML patients benefited preferentially more from GO treatment as compared to AML patients with abnormal cytogenetics (hazard ratio for death, 0.52 versus 1.14; test for interaction, P = 0.04). Although the interaction test was not statistically significant, the OS benefit associated with GO treatment appeared also more pronounced in FLT3 internal tandem duplication positive than in negative patients.

Pneumococcal meningitis is the most common and severe form of bacterial meningitis. Fatality rates are substantial, and long-term sequelae develop in about half of survivors. Disease outcome has been related to the severity of the proinflammatory response in the subarachnoid space. The complement system, which mediates key inflammatory processes, has been implicated as a modulator of pneumococcal meningitis disease severity in animal studies. Additionally, SNPs in genes encoding complement pathway proteins have been linked to susceptibility to pneumococcal infection, although no associations with disease severity or outcome have been established. Here, we have performed a robust prospective nationwide genetic association study in patients with bacterial meningitis and found that a common nonsynonymous complement component 5 (C5) SNP (rs17611) is associated with unfavorable disease outcome. C5 fragment levels in cerebrospinal fluid (CSF) of patients with bacterial meningitis correlated with several clinical indicators of poor prognosis. Consistent with these human data, C5a receptor–deficient mice with pneumococcal meningitis had lower CSF wbc counts and decreased brain damage compared with WT mice. Adjuvant treatment with C5-specific monoclonal antibodies prevented death in all mice with pneumococcal meningitis. Thus, our results suggest C5-specific monoclonal antibodies could be a promising new antiinflammatory adjuvant therapy for pneumococcal meningitis. PMID:21926466

To assess long-term neurodevelopmental outcome in children with hydrocephalus requiring neurosurgical treatment during the neonatal period. This prospective longitudinal population-based study included 43 children with neonatal shunted hydrocephalus. The 43 children were prospectively reviewed in the presence of their parents at the outpatient clinic. Cognitive and motor outcomes were assessed respectively using different Wechsler scales according to age and Gross Motor Function Classification System (GMFCS). Postoperative MRI was routinely performed. The mean gestational age at birth of the 43 consecutive children with neonatal hydrocephalus (sex ratio M/F: 1.39) was 34.5±5.4 weeks of gestation. At mean follow-up of 10.4±4 years, mean total IQ was 73±27.7, with equivalent results in mean verbal and mean performance IQ. Of the 33 children with IQ evaluation, 18 presented an IQ≥85 (41.9%). Efficiency in walking without a mobility device (GMFCS≤2) was obtained in 37 children (86%). Only severity of postoperative ventricular dilation was significantly associated with unfavorable outcome (Evans index>0.37; odds ratio: 0.16, P=0.03). This information could be provided to those families concerned who often experience anxiety when multi-disciplinary management of neonatal hydrocephalus is required.

The purpose of this study was to assess patient adherence to an oral preventive measures (OPM) protocol and its impact on cancer treatment outcomes. A retrospective cohort of oral cancer of 133 patients submitted to radiotherapy (RT) was selected, excluding those with metastasis. Patients were grouped according to their local tumor response after finishing RT (favorable or unfavorable) and adherence to an OPM (none, ≤6 months, and >6 months). OPM included education and counseling about adverse effects, elimination of infection foci, restorative procedures, fluoride therapy, oral rehydration, and maintenance and supervision of oral hygiene throughout treatment. Clinical and pathological characteristics were recorded, and patient outcomes (frequency of adverse effects, RT interruption, and overall survival) were analyzed. Patients with higher adherence to the OPM had greater occurrence of RT interruption as a consequence of symptoms (p = 0.01); however, these patients were more likely to complete the established RT protocol (p = 0.02). Overall survival (p = 0.01) was higher in the group with higher adherence. This study suggests that the implementation of oral preventive measures may contribute to improving the prognosis of squamous cell carcinoma (SCC) treatment by reducing the negative impact of oral complications.

Background Neuroblastoma is the most common extracranial pediatric solid cancer. Lung metastasis is rarely detected in children with newly diagnosed neuroblastoma. We aimed to describe the incidence, clinical characteristics, and outcome of patients with lung metastasis at initial diagnosis using a large international database. Procedure The subset of patients from the International Neuroblastoma Risk Group database with INSS stage 4 neuroblastoma and known data regarding lung metastasis at diagnosis was selected for analysis. Clinical and biological characteristics were compared between patients with and without lung metastasis. Survival for patients with and without lung metastasis was estimated by Kaplan-Meier methods. Cox proportional hazards methods were used to determine the independent prognostic value of lung metastasis at diagnosis. Results Of the 2,808 patients with INSS stage 4 neuroblastoma diagnosed between 1990 and 2002, 100 patients (3.6%) were reported to have lung metastasis at diagnosis. Lung metastasis was more common among patients with MYCN amplified tumors, adrenal primary tumors, or elevated lactate dehydrogenase (LDH) levels (p < 0.02 in each case). Five-year overall survival ± standard error for patients with lung metastasis was 34.5% ± 6.8% compared to 44.7% ± 1.3% for patients without lung metastasis (p=0.0002). However, in multivariable analysis, the presence of lung metastasis was not independently predictive of outcome. Conclusions Lung metastasis at initial diagnosis of neuroblastoma is associated with MYCN amplification and elevated LDH levels. Although lung metastasis at diagnosis was not independently predictive of outcome in this analysis, it remains a useful prognostic marker of unfavorable outcome. PMID:18649370

BACKGROUND: Chemotherapy with high-dose methotrexate (HD-MTX) followed by whole brain radiotherapy (WBRT) is a conventional approach to treat primary central nervous system lymphomas (PCNSL), but some tumors relapse early leading to unfavorable outcome. Several biomarkers have been identified as prognostic factors in PCNSL, however, the correlation of both clinical factors including those related to MTX metabolism and B-cell differentiation and oncogenic biomarkers with response to and outcome by therapy is yet unclear. METHODS: We investigated 32 immunocompetent patients (19 males, 13 females) with PCNSL (all diffuse large B-cell type) treated with HD-MTX based therapy with or without WBRT since 2000 in our institution. Paraffin-embedded formalin-fixed tumor tissue sections were stained immunohistochemically with antibodies against following factors: B-cell differentiation markers (CD10, Bcl-6, Mum-1, CD138); MTX metabolism-related (MRP family, LRP, DHFR); cell cycle-related (p27KIP1, MIB-1); drug resistance-related (MGMT, MLH1, MSH2, MSH6, PMS2); and oncogenes (Myc, Bcl-2). Correlation between positivity of these factors and clinical outcomes were evaluated using logrank test and cox regression analysis. RESULTS: Among these factors, complete response to HD-MTX was significantly associated with longer progression-free survival (PFS)(P = 0.0012), while Bcl-6 expression as well as histological subtype (non-germinal center B-cell, non-GCB) was closely correlated with shorter PFS. Age (>60) (P = 0.006) and MSH2 expression (P = 0.017) were found to be better predictor for overall survival (OS), but in multivariate analysis, they were no longer significant. Other factors involved in MTX metabolism, DNA repair enzymes, and oncogenes did not affect outcome. CONCLUSIONS: Non-GCB subtype and Bcl-6 expression may be associated with worse outcome in patients with PCNSL treated with HD-MTX, while MTX-metabolism related factors did not influence prognosis. Further investigation is needed to assess Bcl-6 as a potential prognostic factor in PCNSL. SECONDARY CATEGORY: Clinical Neuro-Oncology.

To analyze the incidence and outcome of prehospital cardiac arrest as it correlated to gender and age as a secondary end point in an interventional clinical trial. This prospective, randomized, double-blinded clinical intervention trial enrolled 874 prehospital cardiopulmonary arrest patients encountered by prehospital urban, suburban, and rural regional emergency medical service (EMS) areas. This trial evaluated outcome and profiled demographic predictors of cardiac arrest patients refractory to defibrillation with intravenous access who underwent standard advanced cardiac life support (ACLS) intervention and empiric early administration of bicarbonate. Survival was measured to the emergency department (ED), and data analysis used chi-square with Pearson correlation. The overall survival rate was 14.2%. There was no age correlate to survival, with an average age of 67.4 for both groups. Male patients had a 2.4-fold increased incidence (70.7 vs. 29.3%, p = 0.001) of arrest, which was associated with a 60% increase in mortality (19.6% vs. 11.8, p = 0.004) compared with women. The risk of unfavorable outcome was increased for men (OR 1.826, 95% CI 1.182-2.821; RR 1.097, 95% CI 1.025-1.180) on univariate analysis. There appeared to be no intergroup differences found with other historical variables, such as the presence of myocardial infarction (MI), hypertension (HTN), diabetes mellitus (DM), congestive heart failure (CHF), and chronic obstructive pulmonary disease (COPD), which were analyzed. However, HTN was found more commonly (2.2 times) in men (69.1 vs. 30.9%) than in women but did not correlate with survival. Male gender, but not age, is associated with both an increased incidence and a worsened outcome in prehospital cardiac arrest.

Dyskerin mediates both the modification of uridine on ribosomal and small nuclear RNAs and the stabilization of the telomerase RNA component (TERC). In human tumors dyskerin expression was found to be associated with both rRNA modification and TERC levels. Moreover, dyskerin overexpression has been linked to unfavorable prognosis in a variety of tumor types, however an explanation for the latter association is not available. To clarify this point, we analyzed the connection between dyskerin expression, TERC levels and clinical outcome in two series of primary lung cancers, differing for the presence of TERC gene amplification, a genetic alteration inducing strong TERC overexpression. TERC levels were significantly higher in tumors bearing TERC gene amplification (P = 0.017). In addition, the well-established association between dyskerin expression and TERC levels was observed only in the series without TERC gene amplification (P = 0.003), while it was not present in TERC amplified tumors (P = 0.929). Similarly, the association between dyskerin expression and survival was found in cases not bearing TERC gene amplification (P = 0.009) and was not observed in TERC amplified tumors (P = 0.584). These results indicate that the influence of dyskerin expression on tumor clinical outcome is linked to its role on the maintenance of high levels of TERC. PMID:26301749

The study aimed to determine the clinical forms of tuberculosis and therapeutic outcome of anti-tuberculosis treatment in the context of HIV-tuberculosis co-infection. A retrospective cohort of 120 HIV-positive patients with tuberculosis and 297 HIV-negative patients with tuberculosis attending the Kabinda Center was followed from 2010 to June, 30th 2013. The logistic regression model identified the determinants of a defavorable outcome after initiation of tuberculostatics. The proportion of female patients was higher in the co-infected group compared with the non-co-infected group (60.8% versus 42.7%, P<0.001). HIV-seropositive patients had more forms of pulmonary smear-negative (39.2% versus 25.3%, P<0.002) and extra-pulmonary (38% versus 35%, P<0.002) tuberculosis than HIV-negative patients. HIV-positive serology (OR: 3.13, 95%CI: 1.72-5.69) and age of patients more than 41 years (OR: 3.15, 95%CI: 1.36-7.29) were associated with an unfavorable outcome. This study highlights the usefulness of a systematically determining immunological status in co-infected patients and a timely and systematic ARV treatment, together with early diagnosis of tuberculosis. It also emphasizes the importance of adherence to support measures in order to improve tuberculosis treatment outcomes in co-infected patients. Copyright © 2015 Elsevier Masson SAS.

We examined Genotype × Environment (G × E) interactions between children’s genotypes (the serotonin transporter linked promoter region [5-HTTLPR] gene) and maternal responsive care observed at 15, 25, 38, and 52 months on three aspects of children’s competence at 67 months: academic skills and school engagement, social functioning with peers, and moral internalization that encompassed prosocial moral cognition and the moral self. Academic and social competence outcomes were reported by both parents, and moral internalization was observed in children’s narratives elicited by hypothetical stories and in a puppet interview. Analyses revealed robust G × E interactions, such that children’s genotype moderated the effects of maternal responsive care on all aspects of children’s competence. Among children with a short 5-HTTLPR allele (ss/sl), those whose mothers were more responsive were significantly more competent than those whose mothers were less responsive. Responsiveness had no effect for children with two long alleles (ll). For academic and social competence, the G × E interactions resembled the diathesis–stress model: ss/sl children of unresponsive mothers had particularly unfavorable outcomes, but ss/sl children of responsive mothers had no worse outcomes than ll children. For moral internalization, the G × E interaction reflected the differential susceptibility model: whereas ss/sl children of unresponsive mothers again had particularly unfavorable outcomes, ss/sl children of responsive mothers had significantly better outcomes than ll children.

OBJECTIVE This study identifies quantitative imaging-based measures in patients with Chiari malformation Type I (CM-I) that are associated with positive outcomes after suboccipital decompression with duraplasty. METHODS Fifteen patients in whom CM-I was newly diagnosed underwent MRI preoperatively and 3 months postoperatively. More than 20 previously described morphological and physiological parameters were derived to assess quantitatively the impact of surgery. Postsurgical clinical outcomes were assessed in 2 ways, based on resolution of the patient's chief complaint and using a modified Chicago Chiari Outcome Scale (CCOS). Statistical analyses were performed to identify measures that were different between the unfavorable- and favorable-outcome cohorts. Multivariate analysis was used to identify the strongest predictors of outcome. RESULTS The strongest physiological parameter predictive of outcome was the preoperative maximal cord displacement in the upper cervical region during the cardiac cycle, which was significantly larger in the favorable-outcome subcohorts for both outcome types (p < 0.05). Several hydrodynamic measures revealed significantly larger preoperative-to-postoperative changes in the favorable-outcome subcohort. Predictor sets for the chief-complaint classification included the cord displacement, percent venous drainage through the jugular veins, and normalized cerebral blood flow with 93.3% accuracy. Maximal cord displacement combined with intracranial volume change predicted outcome based on the modified CCOS classification with similar accuracy. CONCLUSIONS Tested physiological measures were stronger predictors of outcome than the morphological measures in patients with CM-I. Maximal cord displacement and intracranial volume change during the cardiac cycle together with a measure that reflects the cerebral venous drainage pathway emerged as likely predictors of decompression outcome in patients with CM-I.

BACKGROUND: This study aimed to prospectively evaluate clinical, histopathological and molecular variables for outcome prediction in medulloblastoma patients. METHODS: Patients from the HIT2000 cooperative clinical trial were prospectively enrolled based on the availability of sufficient tumor material and complete clinical information. This revealed a cohort of 184 patients (median age 7.6 years), which was randomly split at a 2:1 ratio into a training (n = 127), and a validation (n = 57) dataset. All samples were subjected to thorough histopathological investigation, CTNNB1 mutation analysis, quantitative PCR, MLPA and FISH analyses for cytogenetic variables, and methylome analysis. RESULTS: By univariable analysis, clinical factors (M-stage), histopathological variables (large cell component, endothelial proliferation, synaptophysin pattern), and molecular features (chromosome 6q status, MYC amplification, TOP2A copy-number, subgrouping) were found to be prognostic. Molecular consensus subgrouping (WNT, SHH, Group 3, Group 4) was validated as an independent feature to stratify patients into different risk groups. When comparing methods for the identification of WNT-driven medulloblastoma, this study identified CTNNB1 sequencing and methylation profiling to most reliably identify these patients. After removing patients with particularly favorable (CTNNB1 mutation, extensive nodularity) or unfavorable (MYC amplification) markers, a risk score for the remaining “intermediate molecular risk” population dependent on age, M-stage, pattern of synaptophysin expression, and MYCN copy-number status was identified and validated, with speckled synaptophysin expression indicating worse outcome. CONCLUSIONS: Methylation subgrouping and CTNNB1 mutation status represent robust tools for the risk-stratification of medulloblastoma. A simple clinico-pathological risk score for “intermediate molecular risk” patients was identified, which deserves further validation. SECONDARY CATEGORY: Pediatrics.

To investigate the anatomical and refractive outcomes in patients with Type 1 retinopathy of prematurity in Zone I. The medical records of 101 eyes of 51 consecutive infants with Type 1 retinopathy of prematurity in Zone I were analyzed. Infants were treated by conventional laser photocoagulation (Group I), combined intravitreal bevacizumab injection and Zone I sparing laser (Group II), or intravitreal bevacizumab with deferred laser treatment (Group III). The proportion of unfavorable anatomical outcomes including retinal fold, disc dragging, retrolental tissue obscuring the view of the posterior pole, retinal detachment, and early refractive errors were compared among the three groups. The mean gestational age at birth and the birth weight of all 51 infants were 24.3 ± 1.1 weeks and 646 ± 143 g, respectively. In Group I, an unfavorable anatomical outcome was observed in 10 of 44 eyes (22.7%). In contrast, in Groups II and III, all eyes showed favorable anatomical outcomes without reactivation or retreatment. The refractive error was less myopic in Group III than in Groups I and II (spherical equivalent of -4.62 ± 4.00 D in Group I, -5.53 ± 2.21 D in Group II, and -1.40 ± 2.19 D in Group III; P < 0.001). In Type 1 retinopathy of prematurity in Zone I, intravitreal bevacizumab with concomitant or deferred laser therapy yielded a better anatomical outcome than conventional laser therapy alone. Moreover, intravitreal bevacizumab with deferred laser treatment resulted in less myopic refractive error.

To evaluate the incidence and risk factors of pressure ulcers (PU) in adult patients admitted to intensive care units (ICUs), as well as the outcome (including ICU and hospital mortality) of these patients. Epidemiological cohort multicenter prospective study, evaluating patients admitted for a period of 31days (June 01 to July 01, 2015) until hospital discharge. Epidemiological and clinical data were collected daily until ICU discharge, as was the incidence of PU, either new or present on admission. 10 general adult ICUs. We evaluated 332 patients, 52.1% male, mean age 63.1 years. The most common cause of admission was medical diseases (50.3%), and the mean APACHE II score was 14.9. A total of 45 patients (13.6%) had PU; the most common sites were sacral, calcaneal, ears, and trochanter. The incidence of PU was related to predictive factors, such as the Braden Scale and length of lack of nutrition. The presence of PU was strongly related to unfavorable outcomes, such as Mechanical Ventilation (MV) duration and ICU and hospital mortality. PU incidence is related to severity of the patient's condition and predicted by Braden Scale score. The presence of PU is also related to adverse outcomes, such as MV duration and ICU and hospital mortality. It was also shown that patients with PU have a higher incidence of medical complications, such as acute renal failure, pneumonia, and the need for vasoactive drugs. Copyright © 2017 Elsevier Ltd.

Mucormycosis is a fulminant fungal infection that occurs most often in diabetic and immunocompromised individuals. Our patient, with uncontrolled diabetes mellitus and multiple systemic disorders, developed postextraction mucormycosis of mandible, an extremely rare complication. An initial clinical and radiographic diagnosis of mandibular osteomyelitis was made and the lesion was treated medically and surgically with curettage and saucerisation. The specimen was sent for histopathological evaluation, which showed necrotic area containing broad aseptate fungal hyphae with right angle branching consistent with mucormycosis. The patient succumbed to multipleorgan failure secondary to septicemia. The disease is usually fatal with a poor survival rate; there is still paucity of literature on the definitive management of this disease involving the mandible. This paper emphasizes the need for correction of underlying immunodeficiency and early diagnosis with aggressive multimodality treatment approach to offer the best chance of survival. PMID:22779014

Head CT after out-of-hospital cardiac arrest is often obtained to evaluate intracranial pathology. Among children admitted to the PICU following pediatric out-of-hospital cardiac arrest, we hypothesized that loss of gray-white matter differentiation and basilar cistern and sulcal effacement are associated with mortality and unfavorable neurologic outcome. Retrospective, cohort study. Single, tertiary-care center PICU. Seventy-eight patients less than 18 years old who survived out-of-hospital cardiac arrest to PICU admission and had a head CT within 24 hours of return of spontaneous circulation were evaluated from July 2005 through May 2012. None. Median time to head CT from return of spontaneous circulation was 3.3 hours (1.0, 6.0). Median patient age was 2.3 years (0.4, 9.5). Thirty-nine patients (50%) survived, of whom 29 (74%) had favorable neurologic outcome. Nonsurvivors were more likely than survivors to have 1) loss of gray-white matter differentiation (Hounsfield unit ratios, 0.96 [0.88, 1.07] vs 1.1 [1.07, 1.2]; p < 0.001), 2) basilar cistern effacement (93% vs 7%; p = 0.001; positive predictive value, 94%; negative predictive value, 59%), and 3) sulcal effacement (100% vs 0%; p ≤ 0.001; positive predictive value, 100%; negative predictive value, 68%). All patients with poor gray-white matter differentiation or sulcal effacement had unfavorable neurologic outcomes. Only one patient with basilar cistern effacement had favorable outcome. Loss of gray-white matter differentiation and basilar cistern effacement and sulcal effacement are associated with poor outcome after pediatric out-of-hospital cardiac arrest. Select patients may have favorable outcomes despite these findings.

There are limited data on which patients not treated with intravenous (IV) tissue-type plasminogen activator (tPA) due to mild and rapidly improving stroke symptoms (MaRISS) have unfavorable outcomes. Acute ischemic stroke (AIS) patients not treated with IV tPA due to MaRISS from January 1, 2009 to December 31, 2013 were identified as part of the Georgia Coverdell Acute Stroke Registry. Multivariable regression analysis was used to identify factors associated with a lower likelihood of favorable outcome, defined as discharge to home. There were 1614 AIS patients who did not receive IV tPA due to MaRISS (median National Institutes of Health stroke scale [NIHSS] 1], of which 305 (19%) did not have a favorable outcome. Factors associated with lower likelihood of favorable outcome included Medicare insurance status (odds ratio [OR]: .53, 95% confidence interval [CI]: .34-.84), arrival by emergency medical services (OR: .46, 95% CI: .29-.73), increasing NIHSS score (per unit OR: .89, 95% CI: .84-.93), weakness as the presenting symptom (OR: .50, 95% CI: .30-.84), and a failed dysphagia screen (OR: .43, 95% CI: .23-.80). During the study period, <1% of patients presenting to participating hospitals with MaRISS within the eligible time window received IV tPA. Baseline characteristics, presenting symptoms, and response to dysphagia screen identify a subgroup of patients who are more likely to have an unfavorable outcome. Whether IV tPA treatment can improve the outcome in this subgroup of patients needs to be evaluated in a randomized placebo-controlled trial. Copyright © 2016 National Stroke Association.

Infections occur in 30% of stroke patients and are associated with unfavorable outcomes. Preventive antibiotic therapy lowers the infection rate after stroke, but the effect of preventive antibiotic treatment on functional outcome in patients with stroke is unknown. The PASS is a multicenter, prospective, phase three, randomized, open-label, blinded end-point (PROBE) trial of preventive antibiotic therapy in acute stroke. Patients are randomly assigned to either ceftriaxone at a dose of 2 g, given every 24 h intravenously for 4 days, in addition to standard stroke-unit care, or standard stroke-unit care without preventive antibiotic therapy. The aim of this study is to assess whether preventive antibiotic treatment improves functional outcome at 3 months by preventing infections. This paper presents in detail the statistical analysis plan (SAP) of the Preventive Antibiotics in Stroke Study (PASS) and was submitted while the investigators were still blinded for all outcomes. The primary outcome is the score on the modified Rankin Scale (mRS), assessed by ordinal logistic regression analysis according to a proportional odds model. Secondary analysis of the primary outcome is the score on the mRS dichotomized as a favorable outcome (mRS 0 to 2) versus unfavorable outcome (mRS 3 to 6). Secondary outcome measures are death rate at discharge and 3 months, infection rate during hospital admission, length of hospital admission, volume of post-stroke care, use of antibiotics during hospital stay, quality-adjusted life years and costs. Complications of treatment, serious adverse events (SAEs) and suspected unexpected serious adverse reactions (SUSARs) are reported as safety outcomes. The data from PASS will establish whether preventive antibiotic therapy in acute stroke improves functional outcome by preventing infection and will be analyzed according to this pre-specified SAP.

Despite its high prevalence among patients with aneurysmal subarachnoid hemorrhage (aSAH) and high risk of delayed cerebral ischemia (DCI), the Fisher grade 3 category remains a poorly studied subgroup. The aim of this cohort study has been to investigate the prognostic value of the Hijdra sum scoring system for the functional outcome in patients with Fisher grade 3 aSAH, in order to improve the risk stratification within this Fisher category. Initial CT scans of 72 prospectively enrolled patients with Fisher grade 3 aSAH were analyzed, and cisternal, ventricular, and total amount of blood were graded according to the Hijdra scale. Additionally, space-occupying subarachnoid blood clots were assessed. Outcome was evaluated after 6 months. Within the subgroup of Fisher grade 3, aSAH patients with an unfavorable outcome showed a significantly larger cisternal Hijdra sum score (HSS: 21.1 ± 5.2) than patients with a favorable outcome (HSS: 17.6 ± 5.9; p = 0.009). However, both the amount of ventricular blood (p = 0.165) and space-occupying blood clots (p = 0.206) appeared to have no prognostic relevance. After adjusting for the patient's age, gender, tobacco use, clinical status at admission, and presence of intracerebral hemorrhage, the cisternal and total HSS remained the only independent parameters included in multivariate logistic regression models to predict functional outcome (p < 0.01). The cisternal Hijdra score is fairly easy to perform and the present study indicates that it has an additional predictive value for the functional outcome within the Fisher 3 category. We suggest that the Hijdra scale is a practically useful prognostic instrument for the risk evaluation after aSAH and should be applied more often in the clinical setting.

Hilar cholangiocarcinomas are malignant tumors with a poor prognosis. An early prediction of prognosis for patients may help us determine treatment strategies. Aquaporin 1 is a cell membrane channel involved in water transport, cell motility, and proliferation. Increasing evidences showed that aquaporin 1 played a role in tumor prognosis and diagnosis. The purpose of this study is to evaluate the role of aquaporin 1 in hilar cholangiocarcinoma. Here, we analyzed messenger RNA expression data of genes function as bile secretion in a data set of 169 samples using the R2 bioinformatic platform ( http://r2.amc.nl ). Quantitative polymerase chain reaction was performed to verify the gene expression in 17 hilar cholangiocarcinoma samples. Immunohistochemistry was also performed in a series of specimens from 62 hilar cholangiocarcinoma tissues, and its clinical significance was assessed by clinical correlation and Kaplan-Meier analyses. All data were analyzed using the R2 web application, aquaporin 1 was selected for further analysis. The significant expression variation of aquaporin 1 among 17 cases with cholangiocarcinoma was also found using quantitative polymerase chain reaction. The expression level of aquaporin 1 protein significantly correlated with tumor-node-metastasis stage ( P = .002) and overall survival time ( P = .010). Higher aquaporin 1 expression indicated poor prognostic outcomes ( P <.05, log-rank test). Multivariate analysis also showed strong aquaporin 1 protein expression was an independent adverse prognosticator in hilar cholangiocarcinoma ( P = .002). This study highlighted the prognostic value of aquaporin 1 in hilar cholangiocarcinoma. Strong aquaporin 1 expression predicts poor survival, regardless of pathological features. Immunohistochemical detection of aquaporin 1, as a prognostic marker, may contribute to predicting clinical outcome for patients with hilar cholangiocarcinoma.

To describe visual function and associated characteristics at the 6-year examination in children enrolled in the Early Treatment for Retinopathy of Prematurity Study who had unfavorable visual outcomes despite favorable structural outcomes in one or both eyes. The clinical examination records of children completing the 6-year follow-up examination were retrospectively reviewed. Eligible subjects were those with visual acuity of ≤20/200 in each eye (where recordable) and a normal fundus or straightening of the temporal retinal vessels with or without macular ectopia in at least one eye. Data regarding visual function, retinal structure, presence of nystagmus, optic atrophy, optic disk cupping, seizures/shunts, and Functional Independence Measure for Children (ie, WeeFIM: pediatric functional independence measure) developmental test scores were reviewed. Of 342 participants who completed the 6-year examination, 39 (11%) met inclusion criteria. Of these, 29 (74%) had normal retinal structure, 18 (46%) had optic atrophy, and 3 (8%) had increased cupping of the optic disk in at least one eye. Latent and/or manifest nystagmus occurred in 30 children (77%). The presence of nystagmus was not related to the presence of optic atrophy. Of the 39 children, 28 (72%) had a below-normal WeeFIM score. In 25 participants (7%) completing the 6-year examination, cortical visual impairment was considered the primary cause of visual loss. The remainder likely had components of both anterior and posterior visual pathway disease. Clinical synthesis of ocular anatomy and visual and neurologic function is required to determine the etiology of poor vision in these children.

To assess differential relationships between lifetime anxiety disorder/current anxiety symptoms and longitudinal depressive severity in bipolar disorder (BD). Stanford BD Clinic outpatients enrolled during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and followed with the STEP-BD Clinical Monitoring Form while receiving naturalistic treatment for up to two years. Baseline unfavorable illness characteristics/current mood symptoms and times to depressive recurrence/recovery were compared in patients with versus without lifetime anxiety disorder/current anxiety symptoms. Among 105 currently recovered patients, lifetime anxiety disorder was significantly associated with 10/27 (37.0%) demographic/other unfavorable illness characteristics/current mood symptoms/current psychotropics, hastened depressive recurrence (driven by earlier onset age), and a significantly (> two-fold) higher Kaplan-Meier estimated depressive recurrence rate, whereas current anxiety symptoms were significantly associated with 10/27 (37.0%) demographic/other unfavorable illness characteristics/current mood symptoms/current psychotropics and hastened depressive recurrence (driven by lifetime anxiety disorder), but only a numerically higher Kaplan-Meier estimated depressive recurrence rate. In contrast, among 153 currently depressed patients, lifetime anxiety disorder/current anxiety symptoms were not significantly associated with time to depressive recovery or depressive recovery rate. American tertiary BD clinic referral sample, open naturalistic treatment. Research is needed regarding differential relationships between lifetime anxiety disorder and current anxiety symptoms and hastened/delayed depressive recurrence/recovery - specifically whether lifetime anxiety disorder versus current anxiety symptoms has marginally more robust association with hastened depressive recurrence, and whether both have marginally more robust associations with hastened depressive recurrence versus delayed depressive recovery, and related clinical implications.

Presently, no studies have evaluated clinical outcomes or patient-centered outcomes for complete dentures fabricated with computer-aided design and computer aided manufacturing (CAD/CAM) technology. The purpose of this prospective cohort pilot study was to evaluate the clinical and patient-centered outcomes for CAD/CAM monolithic dentures fabricated in 2 visits. Twenty participants with an existing set of maxillary complete dentures opposing either mandibular complete dentures or implant-retained overdentures that required replacement were recruited in this study. A 2-visit duplicate denture protocol was used to fabricate 40 arches of monolithic dentures with CAD/CAM technology. A 100-mm visual analog scale (VAS) instrument was then used to record 12 outcomes at baseline and at 1-year follow-up. Predetermined values were assigned to grade the VAS rating of each outcome as favorable (70.1-100) and unfavorable (≤70). Favorable ratings were sub-divided as excellent (90.1-100), good (80.1-90), and fair (70.1-80). The clinical outcomes were evaluated independently by 2 experienced prosthodontists at baseline and at 1-year follow-up. Patients evaluated the corresponding patient-centered outcomes during the same time intervals. Additional descriptive variables were also recorded. Each clinical and patient-centered outcome was summarized by medians and ranges. Differences in all ratings recorded at baseline and at 1 year were tested by 1-sided sign test (α=.05). Of 20 participants, 3 were lost to follow-up, and 3 were unsatisfied with the digital dentures and withdrew from the study. These 3 participants were considered treatment failures. Of the 14 remaining participants, 9 had implant-retained mandibular overdentures, and 5 had conventional mandibular complete dentures. For clinical outcomes, the 12 studied outcomes were favorably evaluated by the 2 prosthodontist judges at the 1-year follow-up. Evaluations showed minimal differences between baseline and 1 year. An average of 5 emails (0-11) per patient were sent to the laboratory technicians to communicate the improvisation the CAD design of the dentures. An average of 3.3 denture adjustments were needed after insertion (0-10) during the 1-year period. For patient-centered outcomes, median ratings of all 14 participants indicated each of the 12 studied outcomes was favorable at the 1-year recall. Statistically significant improvements in patient ratings from baseline to 1 year were observed for the absence of denture sore spots and treatment time to make the dentures (P<.05). Minor complications related to loss of retention, excessive wear of teeth and the need for additional visits were observed in 5 participants. No other adverse clinical outcomes related to the CAD/CAM dentures were noted in the 14 evaluated participants, and all dentures were intact and in good condition at the 1-year follow-up. Clinical and patient-centered outcomes for CAD/CAM monolithic dentures fabricated using a 2-visit protocol were evaluated favorably at a 1-year follow-up. However, the proportion of excellent and good ratings for overall satisfaction and assessment was higher for patients than clinicians. A considerable amount of the clinician's time and effort was devoted to aiding in the digital process for the fabrication of CAD/CAM dentures.

Poor patient compliance or nonadherence with prescribed treatments can have a significant unfavorable impact on medical costs and clinical outcomes. In the current study, voice-of-the-customer research was conducted to aid in the development of a next-generation low-intensity pulsed ultrasound (LIPUS) bone healing product. An opportunity to improve patient compliance reporting was identified, resulting in the incorporation into the next-generation device of a visual calendar that provides direct feedback to the patient, indicating days for which they successfully completed treatment. Further investigation was done on whether inclusion of the visual calendar improved patient adherence to the prescribed therapy (20 minutes of daily treatment) over a 6-month period. Thus, 12,984 data files were analyzed from patients prescribed either the earlier- or the next-generation LIPUS device. Over the 6-month period, overall patient compliance was 83.8% with the next-generation LIPUS device, compared with 74.2% for the previous version (p<0.0001). Incorporation of the calendar feature resulted in compliance never decreasing below 76% over the analysis period, whereas compliance with the earlier-generation product fell to 51%. A literature review on the LIPUS device shows a correlation between clinical effectiveness and compliance rates more than 70%. Incorporation of stakeholder feedback throughout the design and innovation process of a next-generation LIPUS device resulted in a measurable improvement in patient adherence, which may help to optimize clinical outcomes.

This study was aimed to identify blood-based biomarkers to predict a sustained complete response (CR) after transarterial chemoembolization (TACE) using targeted proteomics. Consecutive patients with HCC who had undergone TACE were prospectively enrolled (training (n = 100) and validation set (n = 80)). Serum samples were obtained before and 6 months after TACE. Treatment responses were evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST). In the training set, the MRM-MS assay identified five marker candidate proteins (LRG1, APCS, BCHE, C7, and FCN3). When this five-marker panel was combined with the best-performing clinical variables (tumor number, baseline PIVKA, and baseline AFP), the resulting ensemble model had the highest area under the receiver operating curve (AUROC) value in predicting a sustained CR after TACE in the training and validation sets (0.881 and 0.813, respectively). Furthermore, the ensemble model was an independent predictor of rapid progression (hazard ratio (HR), 2.889; 95% confidence interval (CI), 1.612-5.178; P value < 0.001) and overall an unfavorable survival rate (HR, 1.985; 95% CI, 1.024-3.848; P value = 0.042) in the entire population by multivariate analysis. Targeted proteomics-based ensemble model can predict clinical outcomes after TACE. Therefore, this model can aid in determining the best candidates for TACE and the need for adjuvant therapy.

Standardization of the diagnostic routine for children with congenital heart disease associated with pulmonary arterial hypertension (PAH-CHD) is crucial, in particular since inappropriate assignment to repair of the cardiac lesions (e.g., surgical repair in patients with elevated pulmonary vascular resistance) may be detrimental and associated with poor outcomes. Thus, members of the Congenital Heart Disease and Pediatric Task Forces of the Pulmonary Vascular Research Institute decided to conduct a survey aimed at collecting expert opinion from different institutions in several countries, covering many aspects of the management of PAH-CHD, from clinical recognition to noninvasive and invasive diagnostic procedures and immediate postoperative support. In privileged communities, the vast majority of children with congenital cardiac shunts are now treated early in life, on the basis of noninvasive diagnostic evaluation, and have an uneventful postoperative course, with no residual PAH. However, a small percentage of patients (older at presentation, with extracardiac syndromes or absence of clinical features of increased pulmonary blood flow, thus suggesting elevated pulmonary vascular resistance) remain at a higher risk of complications and unfavorable outcomes. These patients need a more sophisticated diagnostic approach, including invasive procedures. The authors emphasize that decision making regarding operability is based not only on cardiac catheterization data but also on the complete diagnostic picture, which includes the clinical history, physical examination, and all aspects of noninvasive evaluation.

Kidney grafts are often preserved initially in static cold storage (CS) and subsequently on hypothermic machine perfusion (MP). However, the impact of CS/MP time on transplant outcome remains unclear. We evaluated the effect of prolonged CS/MP time in a single-center retrospective cohort of 59 donation after circulatory death (DCD) and 177 matched donation after brain death (DBD) kidney-alone transplant recipients. With mean overall CS/MP times of 6.0 h/30.0 h, overall incidence of delayed graft function (DGF) was higher in DCD transplants (30.5%) than DBD transplants (7.3%, P < 0.0001). In logistic regression, DCD recipient (P < 0.0001), longer CS time (P = 0.0002), male recipient (P = 0.02), and longer MP time (P = 0.08) were associated with higher DGF incidence. In evaluating the joint effects of donor type (DBD vs. DCD), CS time (<6 vs. ≥6 h), and MP time (<36 vs. ≥36 h) on DGF incidence, one clearly sees an unfavorable effect of MP time ≥36 h (P = 0.003) across each donor type and CS time stratum, whereas the unfavorable effect of CS time ≥6 h (P = 0.01) is primarily seen among DCD recipients. Prolonged cold ischemia time had no unfavorable effect on renal function or graft survival at 12mo post-transplant. Long CS/MP time detrimentally affects early DCD/DBD kidney transplant outcome when grafts were mainly preserved by MP; prolonged CS time before MP has a particularly negative impact in DCD kidney transplantation. © 2016 Steunstichting ESOT.

To determine whether the "Oxygen with Love" (OWL) and diode laser treatment provided in a neonatal intensive care unit has reduced the risk of avoidable blindness caused by retinopathy of prematurity (ROP) over the past decade. A prospective observational cohort study was performed, in which 351 infants were examined for ROP. The inclusion conditions were as follows: preterm infants, birthweight <1500 g or <32 weeks' gestational age, and birth between 1 Jan 2000 to 31 August 2012. From mid-2009, the OWL program was implemented and the ventilation protocols for such infants were amended. We tested whether the incidence of unfavorable structural outcomes of ROP had decreased following these changes. From 2004 to 2012, the survival rates of younger children increased (p < 0.003). From 2005 to 2012, laser treatment rather than cryotherapy was applied, and the incidence of unfavorable structural outcomes of ROP fell from 13% to 5.6% (not significant). From 2009 to 2012, the incidence of ROP decreased from 55% to 29% (p < 0.002). From 1 August 2009 to 31 August 2012, there was less need for ablative treatment for premature infants, with the rate falling from 11.81% to 3.9% (p < 0.03). This improvement was significantly associated with a reduction in the number of days of intubation (p < 0.0017), lower rates of sepsis (p < 0.003), and improvements in postnatal weight gain (p < 0.0002). The introduction of the OWL program, together with lower rates of sepsis, improvements in postnatal weight gain, and the use of diode laser treatment, has reduced the incidence of unfavorable structural outcomes of ROP.

Atypical clinical presentation in acute myocardial infarction (AMI) patients is not uncommon; most studies suggest that it is associated with unfavorable prognosis. Long-term clinical impact differs according to predominant symptom presentation (typical chest pain, atypical chest pain, syncope, cardiac arrest, or dyspnea) in AMI patients. FAST-MI 2010, a nationwide French registry, included 4169 patients with AMI in 213 centers at the end of 2010 (76% of active centers). Demographics, medical history, hospital management, and outcomes were compared according to predominant symptom presentation. Typical chest pain with no other symptom was reported in 3020 patients (68% in STEMI patients, 76% in NSTEMI patients). Atypical chest pain, dyspnea, syncope, and cardiac arrest were reported in 11%, 11%, 5%, and 1%, respectively. Patients with atypical clinical presentation had a higher cardiovascular risk profile and received fewer medications and a less invasive strategy. Using Cox multivariate analysis, atypical chest pain was not associated with higher death rate at 3 years (HR: 0.96, 95% CI: 0.69-1.33, P = 0.78), whereas cardiac arrest (HR: 2.44, 95% CI: 1.00-5.97, P = 0.05), syncope (HR: 1.70, 95% CI: 1.18-2.46, P = 0.005), and dyspnea (HR: 1.66, 95% CI: 1.31-2.10, P < 0.001) were associated with higher long-term mortality compared with patients with typical isolated chest pain. Similar trends were observed in STEMI and NSTEMI populations. Atypical clinical presentation is observed in about 20% of AMI patients. Cardiac arrest, dyspnea, and syncope represent independent predictors of long-term mortality in STEMI and NSTEMI populations. © 2017 Wiley Periodicals, Inc.

The development of incipient caries, or white spot lesions (WSLs), is a significant clinical problem in orthodontics. The purpose of this study was to retrospectively determine the incidence and severity of WSLs by examining pretreatment and posttreatment digital photographs. A total of 332 consecutive finished patients from a university graduate orthodontic clinic were evaluated. Initial and final digital images were compared to assess WSLs. The facial surfaces of the anterior 8 maxillary teeth were analyzed. The percentage area of WSL per total facial tooth surface was calculated to control for magnification differences. Reliability of the method was assessed by comparison with direct clinical examination data. Patient and operator factors, and treatment complexity and outcomes were evaluated as predictors of WSL incidence and severity. Agreement between direct clinical examination and digital photo data was excellent, with an intraclass correlation coefficient 0.88 and a 0.3% average difference between methods. The incidence of at least 1 WSL on the labial surface of the anterior 8 maxillary teeth was 36%. The order of incidence was lateral incisor (34%), canine (31%), premolar (28%), and central incisor (17%). Risk factors for the development of incipient caries during orthodontic treatment were young age (preadolescent) at the start of treatment, number of poor hygiene citations during treatment, unfavorable clinical outcome score, white ethnic group, and inadequate oral hygiene at the initial pretreatment examination. The use of computer software to evaluate digital photos retrospectively is a valid method for assessing the incidence and severity of WSLs on the maxillary anterior incisors, canines, and premolars.

Objective: To investigate the correlation between post-stroke pneumonia and outcome in patients with acute brain infarction. Methods: Consecutive acute cerebral infarction patients who were hospitalized in Department of Neurology, Jinan Military General Hospital were prospectively recruited from August 2010 to August 2014. The baseline data including age, sex, the National Institute of Health Stroke Scale (NIHSS) scores, type of Oxfordshire Community Stroke Project (OCSP: total anterior circulation infarct, partial anterior circulation infarct, posterior circulation infarct and lacunar infarct), fasting blood glucose etc. after admission were recorded. Post-stroke pneumonia was diagnosed by treating physician according to criteria for hospital-acquired pneumonia of the Centers for Disease Control and Prevention. Recovery was assessed by modified Rankin Scale (mRS) 180 days after stroke by telephone interview (mRS≤2 reflected good prognosis, and mRS>2 reflected unfavorable prognosis). Multinominal Logistic regression analysis, Kaplan-Meier curve and log rank test were used. Results: A total of 1 249 patients were enrolled, among them 173 patients were lost during follow-up. A total of 159 patients had post-stroke pneumonia, while 1 090 patients were without post-stroke. Compared with patients without post-stoke pneumonia, patients with post-stroke pneumonia were older (67±13 vs 63±12 years, P =0.000), more severe (NIHSS, 15(14) vs 4(4), P =0.000). Compared with patients without post-stoke pneumonia, more patients with post-stroke pneumonia suffered from heart failure (12.58% vs 3.40%, P =0.000), atrial fibrillation (26.42% vs 8.81%, P =0.000), myocardial infarction (10.06% vs 5.05%, P =0.016), recurrent brain infarction (30.19% vs 22.66%, P =0.045), total anterior circulation infarct type of OCSP (46.54% vs 19.63%, P =0.000), posterior circulation infarct of OCSP (39.62% vs 25.51%, P =0.001); more patients suffered from disorder of consciousness (60.38% vs 9.27%, P =0.000), dysphagia (34.59% vs 19.89%, P =0.000), vomiting (26.42% vs 8.81%, P =0.000), aphasia (35.85% vs 16.61%, P =0.000) since onset. The morbidity of post-stroke pneumonia among patients with unfavorable outcome (29.37%(111/378)) was significantly higher than that among patients with favorable outcome (3.73%(26/698)) ( P =0.000). Post-stroke pneumonia was an independent prognostic factor for long-term unfavorable outcome ( OR =2.414, 95% CI : 1.336-4.361, P =0.004) and long-term mortality ( OR =2.132, 95% CI : 1.229-3.699, P =0.007). According Kaplan-Meier estimation, the cumulative 180 days survival of patients with post-stroke pneumonia was lower than those without post-stroke pneumonia (62.04%(85/137) vs 93.29%(876/939)); Log-rank test: χ 2 =137.32, P =0.000. Conclusions: Acute brain infarction patients with post-stroke pneumonia are older, more severe; more suffering from heart failure, atrial fibrillation, myocardial infarction; more suffering from disorder of consciousness since onset. Post-stroke pneumonia is an independent prognostic factor for long-term unfavorable outcome and for long term mortality in patients with acute brain infarction.

Although BIRC6/Apollon seems to play a critical role as an antiapoptotic regulator, its clinical relevance in acute leukemia remains largely elusive. Therefore, we aimed to investigate BIRC6 gene expression in childhood acute leukemia in relation to clinicopathological characteristics at presentation, therapeutic response, and prognosis. BIRC6 expression level was assessed in 75 children with acute leukemia; 30 patients with acute myeloblastic leukemia (AML) and 45 patients with acute lymphoblastic leukemia (ALL) using real-time quantitative reverse transcriptase-polymerase chain reaction. The median level of BIRC6 expression did not differ significantly between AML and ALL patients. BIRC6 expression level was higher in patients with AML and ALL with extramedullary involvement, white blood cell (WBC) count ≥ 10 × 10(9) /L, and unfavorable cytogenetics at diagnosis. BIRC6 gene expression was higher in patients with unfavorable response to therapy at day 14, those who developed relapse or died in both leukemic groups. The best cutoff value of BIRC6 to predict therapeutic response and disease outcome was determined. AML and ALL patients with BIRC6 overexpression had significantly shorter overall and disease free survivals. This is the first report to study BIRC6 gene in pediatric ALL. Our results suggested that BIRC6 gene expression could be considered as an adverse risk factor in childhood acute leukemia and, hence, could be used to guide therapeutic regimens. © 2012 John Wiley & Sons A/S.

Background: Single nucleotide polymorphism in the interleukin28B (IL28B) gene was recently shown to be associated with a significant increase in response to interferon-α and ribavirin treatment in patients with chronic hepatitis C. Similarly, thyroid disease (TD) occurring during treatment confer an improved sustained virologic response (SVR). Objectives: To determine the role of IL28B genotypes in a cohort of hepatitis C patients who develop TD during treatment and its relationship to SVR. Patients and Methods: IL28B gene profiles including rs12979860, rs12980275 and rs 8099917 and their genotypes were determined in a cohort of 23 hepatitis C patients who developed TD during treatment and their relationship to SVR. Results: Out of 23 studies cases, 19 has one or more favorable genotypes, of which 15 (78.9%) achieved SVR. Eleven has all three unfavorable genotypes and yet achieved 72.7 % SVR. The presence of more than one favorable genotype only correctly predicts SVR vs. non- SVR in ~50 % of cases, i.e. by chance. Conclusions: Despite the small number of subjects, the presence of one or more unfavorable IL28B genotype does not portend a poor SVR prognostic outcome. This suggests that TD in this clinical context may be a critical factor in the achievement of SVR, probably above that of the genetic predisposition. PMID:23087747

The family of type 2 purinergic (P2) receptors, especially P2X7, is responsible for the direct tumor-killing functions of extracellular adenosine triphosphate (ATP), but the precise role of P2X7 in the progression of hepatocellular carcinoma (HCC) remains elusive. This study aims to evaluate prognostic value of P2X7 expression in HCC patients after surgical resection. Expression of P2X7 was assessed by immunohistochemistry in tissue microarrays containing paired tumor and peritumoral liver tissues from 273 patients with HCC who had undergone hepatectomy between 2006 and 2007. Prognostic value of P2X7 expression and clinical outcomes were evaluated. Peritumoral P2X7 expression was significantly higher than intratumoral P2X7 expression. No significant prognostic difference was observed for overall survival for intratumoral P2X7 density, whereas peritumoral P2X7 density indicates unfavorable overall survival in training set and BCLC stage 0-A subset. Besides, peritumoral P2X7 density, which correlated with tumor size, venous invasion, and BCLC stage, was identified as an independent poor prognosticator for overall survival and recurrence-free survival. The association was further validated in validation set. Peritumoral P2X7 is a potential unfavorable prognosticator for overall survival and recurrence free survival in HCC patients after surgical resection. Further external validation and functional analysis should be pursued to evaluate its potential prognostic value and therapeutic significance for HCC patients.

Traumatic injuries represent a considerable public health burden with significant personal and societal costs. The care of the severely injured patient in a trauma system progresses along a continuum that includes numerous interventions being provided by a multidisciplinary group of healthcare personnel. Despite the recent emphasis on quality of care in medicine, there has been little research to direct trauma clinicians and administrators on how optimally to monitor and improve upon the quality of care delivered within a trauma system. Audit filters are one mechanism for improving quality of care and are defined as specific clinical processes or outcomes of care that, when they occur, represent unfavorable deviations from an established norm and which prompt review and feedback. Although audit filters are widely utilized for performance improvement in trauma systems they have not been subjected to systematic review of their effectiveness. To determine the effectiveness of using audit filters for improving processes of care and clinical outcomes in trauma systems. Our search strategy included an electronic search of the Cochrane Injuries Group Specialized Register, the Cochrane EPOC Group Specialized Register, CENTRAL (The Cochrane Library 2008, Issue 4), MEDLINE, PubMed, EMBASE, CINAHL, and ISI Web of Science: (SCI-EXPANDED and CPCI-S). We handsearched the Journal of Trauma, Injury, Annals of Emergency Medicine, Academic Emergency Medicine, and Injury Prevention. We searched two clinical trial registries: 1) The World Health Organization International Clinical Trials Registry Platform and, 2) Clinical Trials.gov. We also contacted content experts for further articles. The most recent electronic search was completed in December 2008 and the handsearch was completed up to February 2009. We searched for randomized controlled trials, controlled clinical trials, controlled before-and-after studies, and interrupted time series studies that used audit filters as an intervention for improving processes of care, morbidity, or mortality for severely injured patients. Two authors independently screened the search results, applied inclusion criteria, and extracted data. There were no studies identified that met the inclusion criteria for this review. We were unable to identify any studies of sufficient methodological quality to draw conclusions regarding the effectiveness of audit filters as a performance improvement intervention in trauma systems. Future research using rigorous study designs should focus on the relative effectiveness of audit filters in comparison to alternative quality improvement strategies at improving processes of care, functional outcomes, and mortality for injured patients.

Does Simultaneous Third Molar Extraction Increase Intraoperative and Perioperative Complications in Orthognathic Surgery?

PubMed

Steinbacher, Derek M; Kontaxis, Katrina L

2016-06-01

Prior to orthognathic surgery, most surgeons recommend third molar extraction. Espoused reasons include potential risk for infection, untoward osteotomies, and worsened postoperative discomfort. However, in addition to being another procedure for the patient, this may necessitate a longer preorthognathic surgery phase. The purpose of this study is to compare the outcomes of orthognathic surgery with staged versus simultaneous third molar extractions. This was a retrospective analysis of patients who underwent orthognathic surgery from 2013 to 2014, with at least a 1-year follow-up period. Patients were stratified into 2 groups: Extraction of third molars at the time of surgery and prior extraction of third molars. Primary outcomes included the occurrence of unfavorable splits, infection, bleeding, malocclusion, and hardware failure. Secondary outcomes were procedure time, postoperative pain, and length of stay. Pearson χ tests and 2-tailed unpaired t tests were performed to determine if there was an association between the simultaneous removal of third molars and the primary and secondary outcome measures, respectively. One hundred patients were included in the study. Forty-nine patients had third molars extracted at the time of surgery and fifty-one did not. Complications included unfavorable split, postoperative infection, mild postoperative bleeding, postoperative malocclusion, and hardware failure. There was no significant difference in the incidence of complications in both groups. Procedure time was not considerably increased with extractions. There was no significant difference in postoperative pain or length of stay between both groups. Removing third molars concurrently with orthognathic surgery does not increase the risk of adverse outcomes, nor does it significantly influence hospital course.

The objective of this study was to develop and validate a new prognostic model for febrile neutropenia (FN). This study comprised 1001 episodes of FN: 718 for the derivation set and 283 for the validation set. Multivariate logistic regression analysis was performed with unfavorable outcome as the primary endpoint and bacteremia as the secondary endpoint. In the derivation set, risk factors for adverse outcomes comprised age ≥ 60 years (2 points), procalcitonin ≥ 0.5 ng/mL (5 points), ECOG performance score ≥ 2 (2 points), oral mucositis grade ≥ 3 (3 points), systolic blood pressure <90 mmHg (3 points), and respiratory rate ≥ 24 breaths/min (3 points). The model stratified patients into three severity classes, with adverse event rates of 6.0 % in class I (score ≤ 2), 27.3 % in class II (score 3-8), and 67.9 % in class III (score ≥ 9). Bacteremia was present in 1.1, 11.5, and 29.8 % of patients in class I, II, and III, respectively. The outcomes of the validation set were similar in each risk class. When the derivation and validation sets were integrated, unfavorable outcomes occurred in 5.9 % of the low-risk group classified by the new prognostic model and in 12.2 % classified by the Multinational Association for Supportive Care in Cancer (MASCC) risk index. With the new prognostic model, we can classify patients with FN into three classes of increasing adverse outcomes and bacteremia. Early discharge would be possible for class I patients, short-term observation could safely manage class II patients, and inpatient admission is warranted for class III patients.

To describe mean intracranial pressure after aneurysmal subarachnoid hemorrhage, to identify clinical factors associated with increased mean intracranial pressure, and to explore the relationship between mean intracranial pressure and outcome. Analysis of a prospectively collected observational database. Neuroscience ICU of an academic hospital. One hundred sixteen patients with subarachnoid hemorrhage and intracranial pressure monitoring. None. Episodes of intracranial pressure greater than 20 mm Hg lasting at least 5 minutes and the mean intracranial pressure for every 12-hour interval were analyzed. The highest mean intracranial pressure was analyzed in relation to demographic characteristics, acute neurologic status, initial radiological findings, aneurysm treatment, clinical vasospasm, and ischemic lesion. Mortality and 6-month outcome (evaluated using a dichotomized Glasgow Outcome Scale) were also introduced in multivariable logistic models. Eighty-one percent of patients had at least one episode of high intracranial pressure and 36% had a highest mean intracranial pressure more than 20 mm Hg. The number of patients with high intracranial pressure peaked 3 days after subarachnoid hemorrhage and declined after day 7. Highest mean intracranial pressure greater than 20 mm Hg was significantly associated with initial neurologic status, aneurysmal rebleeding, amount of blood on CT scan, and ischemic lesion within 72 hours from subarachnoid hemorrhage. Patients with highest mean intracranial pressure greater than 20 mm Hg had significantly higher mortality. When death, vegetative state, and severe disability at 6 months were pooled, however, intracranial pressure was not an independent predictor of unfavorable outcome. High intracranial pressure is a common complication in the first week after subarachnoid hemorrhage in severe cases admitted to ICU. Mean intracranial pressure is associated with the severity of early brain injury and with mortality.

A low muscle mass is prevalent in patients with metastatic colorectal cancer (mCRC) and has been associated with poor treatment outcome. Chemotherapeutic treatment has an additional unfavorable effect on muscle mass. Sufficient protein intake and physical activity are known to induce muscle protein anabolism in healthy individuals, however it is unclear whether optimal nutrition is effective to preserve muscle mass in patients with mCRC during first-line chemotherapy as well. We hypothesize that individual nutritional counseling by a trained dietitian during first-line chemotherapy is effective in preserving muscle mass and may improve clinical outcomes in patients with mCRC. In this multi-center single-blind randomized controlled trial, patients with mCRC scheduled for first-line combination chemotherapy consisting of oxaliplatin and fluoropyrimidine, with or without bevacizumab (n = 110), will be randomized to receive either individualized nutritional counseling by a trained dietitian to achieve a sufficient dietary intake and an adequate physical activity level, or usual care. Outcome measures will be assessed at baseline and after two and four months of treatment. The primary endpoint will be the change in skeletal muscle area (measured by CT-scan) at the first treatment evaluation. Secondary endpoints will be quality of life, physical functioning, treatment toxicity, treatment intensity and survival. Statistical analyses include one-sided t-tests for the primary endpoint and mixed models and the Kaplan-Meier method for secondary endpoints. This randomized controlled trial will provide evidence whether individualized nutritional counseling during chemotherapy is effective in preventing loss of muscle mass in patients with mCRC.

The antifibrinolytic agent tranexamic acid (TXA) has demonstrated clinical benefit in trauma patients with severe bleeding, but its effectiveness in patients with traumatic brain injury (TBI) is unclear. We conducted a systematic review to evaluate the following research question: In ED patients with or at risk of intracranial hemorrhage (ICH) secondary to TBI, does TXA compared to placebo improve patients' outcomes? MEDLINE, EMBASE, CINAHL, and other databases were searched for randomized controlled trial (RCT) or quasi-RCT studies that compared the effect of TXA to placebo on outcomes of TBI patients. The main outcomes of interest included mortality, neurologic function, hematoma expansion, and adverse effects. We used "Grading quality of evidence and strength of recommendations" to assess the quality of trials. Two authors independently abstracted data using a data collection form. Results from studies were pooled when appropriate. Of 1030 references identified through the search, 2 high-quality RCTs met inclusion criteria. The effect of TXA on mortality had a pooled relative risk of 0.64 (95% confidence interval [CI], 0.41-1.02); on unfavorable functional status, a relative risk of 0.77 (95% CI, 0.59-1.02); and on ICH progression, a relative risk of 0.76 (95% CI, 0.58-0.98). No serious adverse effects (such as thromboembolic events) associated with TXA group were reported in the included trials. Pooled results from the 2 RCTs demonstrated statistically significant reduction in ICH progression with TXA and a nonstatistically significant improvement of clinical outcomes in ED patients with TBI. Further evidence is required to support its routine use in patients with TBI. Copyright © 2014 Elsevier Inc. All rights reserved.

Glioneuronal tumors are found in nearly one third patients who undergo surgery for pharmacoresistant epilepsy with temporal lobe being the most common location. Few studies, however have concentrated on the neurological and neuropsychological outcomes after surgery, hitherto none from India. We studied 34 patients with temporal lobe tumors and drug resistant epilepsy. These patients underwent anterior temporal lobectomy or lesionectomy based on the involvement of the hippocampus and mesial temporal structures. The clinical history, EEG, neuropsychology profile and MRI were compared. Seizure outcome was categorized using Engel's classification. At a mean follow up of 62 months, 85.29% of the patients were seizure free (Engel's Class I). All 8 patients with intraoperative electrocorticography (ECoG) guided resection were seizure free. Presence of a residual lesion was significantly associated with persistence of seizures post surgery (p = 0.002). Group analysis revealed no significant shifts in IQ and memory scores postoperatively. There was a significant improvement in the quality of life scores (total and across all subdomains) in all patients (p < 0.001). Postoperative EEG abnormalities predicted unfavorable ​seizure outcome. Surgery for temporal lobe tumors and refractory epilepsy offers complete seizure freedom in majority. Complete surgical excision of the epileptogenic zone is of paramount importance in achieving seizure freedom. Intraoperative electrocorticography (EcoG) is a useful adjunct to ensure complete removal of epileptogenic zone, thus achieving optimal seizure freedom. There is a significant improvement in the quality of life scores (p < 0.001) with no negative impact of surgery on memory and intelligence. Even the patients who are not seizure free can achieve worthwhile improvement post surgery. Copyright © 2015 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

Inflammasome activation mediates inflammation and outcome in humans and mice with pneumococcal meningitis

PubMed Central

2013-01-01

Background Inflammasomes are multi-protein intracellular signaling complexes that have recently been hypothesized to play a role in the regulation of the inflammation response. We studied associations between inflammasome-associated cytokines IL-1β and IL-18 in cerebrospinal fluid (CSF) of patients with bacterial meningitis and clinical outcome, and pneumococcal serotype. In a murine model of pneumococcal meningitis we examined the pathophysiological roles of two inflammasome proteins, NLRP3 (Nod-like receptor protein-3) and adaptor protein ASC (apoptosis-associated speck-like protein). Methods In a nationwide prospective cohort study, CSF cytokine levels were measured and related to clinical outcome and pneumococcal serotype. In a murine model of pneumococcal meningitis using Streptococcus pneumoniae serotype 3, we examined bacterial titers, cytokine profiles and brain histology at 6 and 30 hours after inoculation in wild-type (WT), Asc and Nlrp3 deficient mice. Results In patients with bacterial meningitis, CSF levels of inflammasome associated cytokines IL-1β and IL-18 were related to complications, and unfavorable disease outcome. CSF levels of IL-1β were associated with pneumococcal serotype (p<0.001). In our animal model, Asc and Nlrp3 deficient mice had decreased systemic inflammatory responses and bacterial outgrowth as compared to WT mice. Differences between Asc−/− and WT mice appeared sooner after bacterial inoculation and were more widespread (lower pro-inflammatory cytokine levels in both blood and brain homogenate) than in Nlrp3-/-mice. Nlrp3 deficiency was associated with an increase of cerebral neutrophil infiltration and cerebral hemorrhages when compared to WT controls. Conclusions Our results implicate an important role for inflammasome proteins NLRP3 and ASC in the regulation of the systemic inflammatory response and the development of cerebral damage during pneumococcal meningitis, which may dependent on the pneumococcal serotype.

: In the acute phase of ischemic stroke, the trend of some physiological variables, such as blood glucose (BG), blood pressure, and body temperature (BT), might influence outcome. We aimed to assess the association of hyperglycemia, systolic and diastolic hypertension, and hyperthermia relative to baseline BG, systolic blood pressure, diastolic blood pressure and BT, respectively, in the first 12 h with poor outcome after intravenous thrombolysis (IVT). We conducted a retrospective analysis of data prospectively collected from 200 consecutive anterior ischemic stroke patients treated with IVT. Outcome measures were no neurological improvement at 24 h (National Institutes of Health Stroke Scale (NIHSS) score at 24 h ≥NIHSS score at baseline), and unfavorable functional outcome [modified Rankin Scale (mRS) score 3-6] at 3 months. No neurological improvement at 24 h was noted in 52 (26%) patients and mRS 3-6 at 3 months in 68 (34%) patients. The multivariate analyses showed that odds ratios (ORs) for no neurological improvement at 24 h were higher in patients with hyperglycemia relative to baseline [OR 3.50, 95% confidence interval (CI) 1.43-8.57, P = 0.006], and hyperthermia relative to baseline (OR 2.88, 95% CI 1.20-6.91, P = 0.018). OR for 3-month mRS score 3-6 was higher in patients with hyperthermia relative to baseline (OR 3.05, 95% CI 1.20-7.74, P = 0.019). Hyperglycemia and hyperthermia relative to baseline in the first 12 h after IVT are associated with no neurological improvement at 24 h. Hyperthermia relative to baseline is also associated with unfavorable functional outcome at 3 months.

To create a novel tool to predict favorable neurologic outcomes during ICU stay among children with critical illness. Logistic regression models using adaptive lasso methodology were used to identify independent factors associated with favorable neurologic outcomes. A mixed effects logistic regression model was used to create the final prediction model including all predictors selected from the lasso model. Model validation was performed using a 10-fold internal cross-validation approach. Virtual Pediatric Systems (VPS, LLC, Los Angeles, CA) database. Patients less than 18 years old admitted to one of the participating ICUs in the Virtual Pediatric Systems database were included (2009-2015). None. A total of 160,570 patients from 90 hospitals qualified for inclusion. Of these, 1,675 patients (1.04%) were associated with a decline in Pediatric Cerebral Performance Category scale by at least 2 between ICU admission and ICU discharge (unfavorable neurologic outcome). The independent factors associated with unfavorable neurologic outcome included higher weight at ICU admission, higher Pediatric Index of Morality-2 score at ICU admission, cardiac arrest, stroke, seizures, head/nonhead trauma, use of conventional mechanical ventilation and high-frequency oscillatory ventilation, prolonged hospital length of ICU stay, and prolonged use of mechanical ventilation. The presence of chromosomal anomaly, cardiac surgery, and utilization of nitric oxide were associated with favorable neurologic outcome. The final online prediction tool can be accessed at https://soipredictiontool.shinyapps.io/GNOScore/. Our model predicted 139,688 patients with favorable neurologic outcomes in an internal validation sample when the observed number of patients with favorable neurologic outcomes was among 139,591 patients. The area under the receiver operating curve for the validation model was 0.90. This proposed prediction tool encompasses 20 risk factors into one probability to predict favorable neurologic outcome during ICU stay among children with critical illness. Future studies should seek external validation and improved discrimination of this prediction tool.

Insula involvement in acute cerebral ischemia more likely causes penumbral loss and poor clinical outcome than infarct-sparing insula. Our objective was to prove the hypothesis that abundant collateral circulation represented by distal hyperintense vessels (HV) on MRI alleviates insula infarction and facilitates prognosis. One hundred and fourteen stroke cases with M1 totally occlusion on MR angiography were documented consecutively from 2012 to 2014. The degree of HV was graded as absent, subtle or prominent. Clinical data were recorded retrospectively by reviewing the medical records. The infarct volume on diffusion-weighted image, along with National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS), was used to evaluate the clinical severity and prognosis. The degree of HV was more abundant in insula-uninvolved stroke compared with stroke involving insula infarction (p = 0.026). Insula-involved stroke patients were older (p = 0.039) with a higher percentage of atrial fibrillation history (p = 0.042). Univariate analysis revealed that insula infarction, age, infarct volume and NIHSS predicted unfavorable prognosis of stroke, whereas HV had a favorable effect. The protective effect of HV was confirmed by multivariate analysis. HV is a protective barrier between insula infarction and severity of clinical symptoms among stroke patients.

Psychoneuroimmunology of Early-Life Stress: The Hidden Wounds of Childhood Trauma?

PubMed Central

Danese, Andrea; J Lewis, Stephanie

2017-01-01

The brain and the immune system are not fully formed at birth, but rather continue to mature in response to the postnatal environment. The two-way interaction between the brain and the immune system makes it possible for childhood psychosocial stressors to affect immune system development, which in turn can affect brain development and its long-term functioning. Drawing from experimental animal models and observational human studies, we propose that the psychoneuroimmunology of early-life stress can offer an innovative framework to understand and treat psychopathology linked to childhood trauma. Early-life stress predicts later inflammation, and there are striking analogies between the neurobiological correlates of early-life stress and of inflammation. Furthermore, there are overlapping trans-diagnostic patterns of association of childhood trauma and inflammation with clinical outcomes. These findings suggest new strategies to remediate the effect of childhood trauma before the onset of clinical symptoms, such as anti-inflammatory interventions and potentiation of adaptive immunity. Similar strategies might be used to ameliorate the unfavorable treatment response described in psychiatric patients with a history of childhood trauma. PMID:27629365

Developments in mechanical thrombectomy devices for the treatment of acute ischemic stroke.

PubMed

Mordasini, Pasquale; Gralla, Jan

2016-01-01

Several recent prospective randomized controlled trials of endovascular stroke therapy using latest generation thrombectomy devices, so called stent-retrievers, have shown significantly improved clinical outcome compared to the standard treatment with intra-venous thrombolysis using r-tPA alone. Despite some differences in inclusion criteria between these studies, all required non-invasive vessel imaging to proof occlusion of a major brain supplying vessel. Furthermore, in most studies additional imaging techniques were used to exclude patients with already established large cerebral infarction or unfavorable collateral or penumbral status. Patients with small infarct volume, severe neurological deficits and in whom thrombectomy can be initiated within the first 6 hours after symptom onset seem to benefit the most. Therefore, mechanical thrombectomy using stent-retrievers in addition to intra-venous thrombolysis is recommended for the treatment of acute ischemic stroke with proven major vessel occlusion in the anterior circulation.

Liver abnormalities have a strong impact on clinical outcomes in patients with heart failure (HF), and are known as cardio-hepatic syndrome. The non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS) has been developed to identify liver fibrosis in patients with NAFLD. It remains to be determined whether NFS is associated with cardiovascular prognosis in patients with chronic heart failure (CHF). We calculated NFS in 516 patients with CHF admitted to our hospital. The clinical endpoints were deaths due to progressive HF, myocardial infarction, stroke, and sudden cardiac death, and rehospitalization for worsening HF. There were 173 cardiovascular events noted during a median follow-up of 464 days. Patients with cardiovascular events showed a higher NFS as compared with those without. We divided the patients into four groups according to quartiles of NFS. The proportion of New York Heart Association functional class III/IV and serum brain natriuretic peptide levels were increased with increasing NFS. Kaplan-Meier analysis revealed that cardiovascular event rate was increased with increasing NFS in patients with CHF. In multivariate Cox proportional hazards analysis, NFS was independently associated with cardiovascular events after adjustment for confounding factors. Elevated NFS was associated with unfavorable outcomes in patients with CHF. Liver fibrosis assessed by NFS may provide valuable prognostic information in patients with CHF.

We investigated whether isovolumic acceleration (IVA) under inotropic stimulation as a means of right ventricular (RV) contractile reserve, is a surrogate for hemodynamic burden and has prognostic value in patients with mitral stenosis (MS). Thirty-one pure MS patients and 20 controls underwent cardiac catheterization, exercise test, and dobutamine stress echocardiography. RV fractional area change (FAC), +dP/dt/P(max), RV tissue Doppler indices (isovolumic contraction [IVC] and systolic [S] velocity, and IVA) were measured. Patients were followed-up for the occurrence of cardiac adverse events. Inotropic modulation unmasked statistically significant differences regarding magnitude of changes in IVA, IVC, S, and +dP/dt/P(max), but not RV FAC. Inability to increase IVA more than 6.5 m/s(2) was the only independent determinant of pulmonary capillary wedge pressure >or=18 mm Hg (P=.004). Although MS severity did not predict the RV contractile reserve and pulmonary artery pressure (PAP) behavior during inotropic stimulation, the RV contractile reserve was related to the degree of systolic PAP. IVA increases of <3.4 m/s(2) had 86% sensitivity and 75% specificity to predict unfavorable outcomes during long-term follow-up (20+/-8 months). RV contractile reserve provides complementary data to the hemodynamic significance of MS severity, may contribute to clinical decision making, and be of prognostic value in these patients.

[Resistance studies: when are they indicated?].

PubMed

Angeles Marcos, M

2011-12-01

Cytomegalovirus (CMV) resistance to antiviral drugs is an emerging problem and is due to selection of mutations in the viral genome. Although ganciclovir resistance is the most common and widely studied, there is resistance to all antiviral agents. Risk factors for the development of resistance are the absence of preexisting immunity to CMV, lung and pancreas transplantation, high viral loads, intense concomitant immunosuppressive therapy and prolonged exposure to ganciclovir or suboptimal levels of this drug. Antiviral resistance should be suspected when, despite adequate treatment exposure for 2 weeks, an increase in viral load, or persistence or clinical progression of CMV disease are detected. However, failure to respond cannot always be attributed to antiviral resistance nor does resistance always lead to poor clinical outcome. When resistance is suspected, phenotypic and genotypic confirmation is required. The most common mutations are those in the UL97 gene, which confers ganciclovir resistance. However, foscarnet and cidofovir can be used. The UL54 mutation is not uncommon, whether alone or in combination with UL97 mutations. The combination of UL54 and UL97 mutations is associated with high-grade and multiple resistance. Early detection of resistance is essential to prevent unfavorable outcome and the development of multi-drug resistance. In patients with a slow response to treatment and without mutations associated with resistance, plasma ganciclovir levels and specific CMV immunity should be investigated.

Integrating Early Intervention for Borderline Personality Disorder and Mood Disorders.

Chanen, Andrew M; Berk, Michael; Thompson, Katherine

2016-01-01

Borderline personality disorder (BPD) has been demonstrated to be a reliable and valid construct in young people (adolescents and young adults). Both borderline- and mood-related psychopathology become clinically apparent from puberty through to young adulthood, frequently co-occur, can reinforce one another, and can be difficult to differentiate clinically. This Gordian knot of overlapping clinical features, common risk factors, and precursors to both BPD and mood disorders complicates clinical assessment, prevention, and treatment. Regardless of whether an individual crosses an arbitrary diagnostic threshold, a considerable proportion of young people with borderline- and mood-related psychopathology will develop significant and persistent functional, vocational, and interpersonal impairment and disability during this critical risk and developmental period. There is a clear need for early intervention, but spurious diagnostic certainty risks stigma, misapplication of diagnostic labels, inappropriate treatment, and unfavorable outcomes. This article aims to integrate early intervention for BPD and mood disorders in the clinical context of developmental and phenomenological change and evolution. "Clinical staging," similar to disease staging in general medicine, is presented as a pragmatic, heuristic, and trans-diagnostic framework to guide prevention and intervention. It acknowledges that the early stages of these disorders cannot be disentangled sufficiently to allow for disorder-specific preventive measures and early interventions. Clinical staging defines an individual's location along the continuum of the evolving temporal course of a disorder. Such staging aids differentiation of early or milder clinical phenomena from those that accompany illness progression and chronicity, and suggests the application of appropriate and proportionate intervention strategies.

Determination of the extent of spinal fusion for lumbar degenerative diseases is often difficult due to minor pathologies in the adjacent segment. Although surgical intervention is required, fusion seems to be an overtreatment. Decompression alone may be not enough as this segment is affected by multiple factors such as destabilization, low grade degeneration and an unfavorable biomechanical transition next to a rigid construct. An alternative surgical treatment is a hybrid construct, consisting of fusion and implantation of an interlaminar stabilization device at the adjacent level. The aim of this study was to compare long-term clinical outcome after lumbar fusion with a hybrid construct including an interlaminar stabilization device as "topping-off". A retrospective analysis of 25 lumbar spinal fusions from 2003 to 2010 with additional interlaminar stabilization device was performed. Through a matched case controlled procedure 25 congruent patients who received lumbar spinal fusion in one or two levels were included as a control group. At an average follow-up of 43 months pre- and postoperative pain, ODI, SF-36 as well as clinical parameters, such as leg and back pain, walking distance and patient satisfaction were recorded. Pain relief, ODI improvement and patient satisfaction was significantly higher in the hybrid group compared to the control group. SF-36 scores improved in both groups but was higher in the hybrid group, although without significance. Evaluation of walking distance showed no significant differences. Many outcome parameters present significantly better long-term results in the hybrid group compared to sole spinal fusion. Therefore, in cases with a clear indication for lumbar spinal fusion with the need for decompression at the adjacent level due to spinal stenosis or moderate spondylarthrosis, support of this segment with an interlaminar stabilization device demonstrates a reasonable treatment option with good clinical outcome. Also, the length of the fusion construct can be reduced allowing for a softer and more harmonic transition.

Although psychosocial stress can result in adverse health outcomes, little is known about how perceptions of neighborhood conditions, a measure of environment-derived stress, may impact obesity. We examined the association between perceptions of neighborhood environment and obesity [defined as body mass index (BMI) ≥ 30 kg/m2] among 5907 participants in the Dallas Heart Study, a multi-ethnic, probability-based sample of Dallas County residents. Participants were asked to respond to 18 questions about perceptions of their neighborhood. Using factor analysis, we identified three factors associated with neighborhood perceptions: neighborhood violence, physical environment, and social cohesion. Logistic regression analyses were performed to determine the relationship between each factor (higher quintile = more unfavorable perceptions) and the odds of obesity. Decreasing age, income, and education associated with unfavorable overall neighborhood perceptions and unfavorable perceptions about specific neighborhood factors (p trend <0.05 for all). Increasing BMI was associated with unfavorable perceptions about physical environment (p trend <0.05), but not violence or social cohesion. After adjustment for race, age, sex, income, education, and length of residence, physical environment perception score in the highest quintile remained associated with a 25% greater odds of obesity [OR 1.25,(95% CI 1.03–1.50)]. Predictors of obesity related to environmental perceptions included heavy traffic [OR 1.39,(1.17–1.64)], trash/litter in neighborhood[OR 1.27,(1.01–1.46)], lack of recreational areas[OR 1.21,(1.01–1.46)], and lack of sidewalks[OR 1.25,(95% CI 1.04–1.51)]. Thus, unfavorable perceptions of environmental physical conditions are related to increased obesity. Efforts to improve the physical characteristics of neighborhoods, or the perceptions of those characteristics, may assist in the prevention of obesity in this community. PMID:23404728

The authors assessed the risk factors and outcomes associated with blood-brain barrier (BBB) disruption in patients with severe, nonpenetrating, traumatic brain injury (TBI) requiring decompressive craniectomy. At 2 major neurotrauma centers in Western Australia, a retrospective cohort study was conducted among 97 adult neurotrauma patients who required an external ventricular drain (EVD) and decompressive craniectomy during 2004-2012. Glasgow Outcome Scale scores were used to assess neurological outcomes. Logistic regression was used to identify factors associated with BBB disruption, defined by a ratio of total CSF protein concentrations to total plasma protein concentration > 0.007 in the earliest CSF specimen collected after TBI. Of the 252 patients who required decompressive craniectomy, 97 (39%) required an EVD to control intracranial pressure, and biochemical evidence of BBB disruption was observed in 43 (44%). Presence of disruption was associated with more severe TBI (median predicted risk for unfavorable outcome 75% vs 63%, respectively; p = 0.001) and with worse outcomes at 6, 12, and 18 months than was absence of BBB disruption (72% vs 37% unfavorable outcomes, respectively; p = 0.015). The only risk factor significantly associated with increased risk for BBB disruption was presence of nonevacuated intracerebral hematoma (> 1 cm diameter) (OR 3.03, 95% CI 1.23-7.50; p = 0.016). Although BBB disruption was associated with more severe TBI and worse long-term outcomes, when combined with the prognostic information contained in the Corticosteroid Randomization after Significant Head Injury (CRASH) prognostic model, it did not seem to add significant prognostic value (area under the receiver operating characteristic curve 0.855 vs 0.864, respectively; p = 0.453). Biochemical evidence of BBB disruption after severe nonpenetrating TBI was common, especially among patients with large intracerebral hematomas. Disruption of the BBB was associated with more severe TBI and worse long-term outcomes, but when combined with the prognostic information contained in the CRASH prognostic model, this information did not add significant prognostic value.

To evaluate the efficacy of traumatic brain injury management guided by intracranial pressure monitoring and to explore the specific subgroups for which intracranial pressure monitoring might be significantly associated with improved outcomes based on a classification of the various traumatic brain injury pathophysiologies using the clinical features and CT scans. Retrospective observational multicenter study. Twenty-two hospitals (16 level I trauma centers and six level II trauma centers) in nine provinces in China. Moderate or severe traumatic brain injury patients who were more than 14 years old. Intracranial pressure monitoring. All data were collected by physicians from medical records. The 6-month mortality and favorable outcome were assessed with the Glasgow Outcome Scale Extended score. An intracranial pressure monitor was inserted into 838 patients (58.1%). The mean duration of intracranial pressure monitoring was 4.44 ± 3.65 days. The significant predictors of intracranial pressure monitoring included the mechanism of injury, a Glasgow Coma Scale score of 9-12 at admission that dropped to a score of 3-8 within 24 hours after injury, a Marshall CT classification of III-IV, the presence of a major extracranial injury, subdural hematoma, intraparenchymal lesions, trauma center level, and intracranial pressure monitoring utilization of hospital. The intracranial pressure monitoring and no intracranial pressure monitoring groups did not significantly differ in terms of complications. For the total sample, the placement of intracranial pressure monitoring was not associated with either 6-month mortality (16.9% vs 20.5%; p = 0.086) or 6-month unfavorable outcome (49.4% vs 45.8%; p = 0.175). For patients with a Glasgow Coma Scale score of 3-8 at admission, intracranial pressure monitoring was also not significantly associated with 6-month mortality (20.9% vs 26.0%; p = 0.053) or an unfavorable outcome (56.9% vs 55.5%; p = 0.646). Multivariate logistic regression analyses showed that intracranial pressure monitoring resulted in a significantly lower 6-month mortality for patients who had a Glasgow Coma Scale score of 3-5 at admission (adjusted odds ratio, 0.57; 95% CI, 0.36-0.90; adjusted p = 0.016), those who had a Glasgow Coma Scale score of 9-12 at admission that dropped to 3-8 within 24 hours after injury (adjusted odds ratio, 0.28; 95% CI, 0.08-0.96; adjusted p = 0.043), and those who had a probability of death at 6 months greater than 0.6 (adjusted odds ratio, 0.55; 95% CI, 0.32-0.94; adjusted p = 0.029). There were multiple differences between the intracranial pressure monitoring and no intracranial pressure monitoring groups regarding patient characteristics, injury severity, characteristics of CT scan, and hospital type. Intracranial pressure monitoring in conjunction with intracranial pressure-targeted therapies is significantly associated with lower mortality in some special traumatic brain injury subgroups. The prospective randomized controlled trials specifically investigating these subgroups will be required to further characterize the effects of intracranial pressure monitoring on behavioral outcomes in patients with traumatic brain injury.

Purpose. The principal anatomic contraindication to endovascular aneurysm repair (EVR) is an unfavorable proximal aortic neck. With increasing experience, a greater proportion of patients with unfavorable neck anatomy are being offered EVR. This study aimed to evaluate outcomes in patients with challenging proximal aortic neck anatomy. Methods. Prospectively collected data from 147 consecutive patients who underwent EVR between December 1997 and April 2005 were supplemented with a retrospective review of medical records and radiological images. Unfavorable anatomic features were defined as neck diameter >28 mm, angulation >60 deg., circumferential thrombus >50%, and length <10 mm. Eighty-seven patients with 0 adversemore » features (good necks) were compared with 60 patients with one or more adverse features (hostile necks). Results. Comparing the good neck with the hostile neck group, there were no significant differences in the incidence of primary technical success (p = 0.15), intraoperative adjunctive procedures (p = 0.22), early proximal type I endoleak (<30 days) (p = 1.0), late proximal type I endoleak (>30 days) (p = 0.57), distal type I endoleak (p = 0.40), type III endoleak (p 0.51), secondary interventions (p = 1.0), aneurysm sac expansion (p = 0.44), or 30 day mortality (p = 0.70). The good neck group had a significantly increased incidence of type II endoleak (p = 0.023). By multivariate analysis, the incidence of intraoperative adjunctive procedures was significantly increased in the presence of severe angulation (p = 0.041, OR 3.08, 95% CI 1.05-9.04). Conclusion. Patients with severely hostile proximal aortic neck anatomy may be treated with EVR, although severely angulated necks require additional intraoperative procedures. Early outcomes are encouraging and suggest that indications for EVR may be expanded to include patients with hostile neck anatomy.« less

The data of the nationwide prospective registry of acute cerebral large vessel occlusion (LVO; RESCUE-Japan Registry) were analyzed to know the effect of edaravone, a free radical scavenger, on clinical outcome at 90 days after onset. In this registry, patients with acute cerebral LVO admitted within 24 h after onset were prospectively registered. The effect of various factors including endovascular treatment (EVT), intravenous recombinant tissue plasminogen activator (IV rt-PA), and other medication including edaravone on favorable outcome (modified Rankin scale 0-1) was analyzed. Of the 1,454 registered patients, 1,442 patients (99.2%) had the information of edaravone were analyzed. In total, edaravone group had more patients with favorable outcome compared to non-edaravone group (22.9% vs. 13.8%, p = 0.0006). Edaravone increased favorable outcome in patients treated with IV rt-PA (29.4% vs. 11.1%, p = 0.0107), but not with EVT (21.2% vs. 13.9%, p = 0.309). Logistic regression analysis revealed that higher National Institutes of Health Stroke Scale (NIHSS) score on admission [odds ratio (OR) 0.875, 95% confidence interval (CI) 0.858-0.894] and advanced age (OR 0.963, 95%CI 0.952-0.975) were significantly related to unfavorable outcome. In contrast, IV rt-PA (OR 2.489, 95%CI 1.867-3.319), EVT (OR 1.375, 95%CI 1.013-1.865), and edaravone (OR 1.483, 95%CI 1.027-2.143) were significantly associated with favorable outcome. This analysis indicated that IV rt-PA, EVT, and edaravone were effective to obtain favorable outcome in patients with acute LVO. Combination IV rt-PA with edaravone was more effective.

The predictive value of neurophysiologic assessment on patients' outcome after acute cerebral infarction is poorly understood. The aim of this study was to investigate the prognostic value of motor-evoked potentials (MEPs) and the silent period (SP) on clinical outcome. A total of 202 patients with acute cerebral infarction were prospectively recruited. MEP and SP were recorded from the abductor pollicis brevis of the affected side within 10 days after stroke onset. Patient outcome was measured as the dependency rate. Cortical MEP was induced in 78 patients whereas it was absent in 82 patients. The initial NIHSS (National Institutes of Health Stroke Scale) score was significantly lower in patients with MEP than in those without MEP (P < .001). Regression analysis demonstrated that a left-sided lesion (OR = .391, 95% CI .178-.858, P = .019), NIHSS at admission (OR = .826, 95% CI .744-.917, P < .001), and presence of MEP (OR = 3.918, 95% CI 1.770-8.672, P < .001) were independent predictors of outcome 3 months after stroke. Among patients with MEP, only the contralateral cortical SP value was significantly shorter in the good outcome subgroup (t = 2.541, P = .013). Receiver operating characteristic curve analysis demonstrated that SP was able to predict patients at higher risk of unfavorable outcome 3 months after stroke onset (area under the curve .721, 95% CI .58-.86, P = .008). These data suggested that MEP and SP were useful tools to predict patients' acute outcomes following cerebral infarction. Copyright © 2016 National Stroke Association. Published by Elsevier Inc.

Few studies have examined the risk of computed tomography angiography (CTA) during the acute phase of spontaneous intracerebral hemorrhage (ICH), while the benefits of CTA in ICH have been well-documented. The present study investigated both the benefits of identifying spot signs, which are supposed to indicate hematoma enlargement after admission, and risks of CTA performed during the acute phase of ICH. We retrospectively assessed 323 consecutive patients with spontaneous ICHs admitted to our hospital between April 2009 and March 2012 and who underwent CTA on admission. In 80 patients (24.7 %), spot signs were demonstrated on CTA source images. Multivariate analysis revealed two independent factors correlated with presence of the spot sign: age and hematoma volume (p < 0.05 each). The presence of spot sign was associated with unfavorable outcomes at discharge and hematoma growth after admission (p < 0.05 each). Adverse events related to CTA occurred in 17 patients (5.2 %), including transient renal dysfunction in 16 patients and allergy to contrast medium in one patient. All adverse events completely resolved within 1 week. Presence of the spot sign indicated the possibility of hematoma growth and unfavorable outcomes. A small number of adverse events occurred in association with CTA, but without any permanent deficits. Given the potential benefits and risks, we believe that CTA performed at admission in all patients with ICH is beneficial to improve the outcomes.

Acute leukemia (AL) and myelodysplastic syndrome (MDS) are uncommon in CLL. We retrospectively identified 95 patients with CLL also diagnosed with AL (n=38) or MDS (n=57), either concurrently (n=5) or subsequent (n=90) to CLL diagnosis and report their outcomes. Median number of CLL treatments prior to AL and MDS was 2(0–9) and 1(0–8), respectively; the most common regimen was purine analogue combined with alkylating agent±CD20 mAb. Twelve had no prior CLL treatment. Among 38 with AL, 33 had AML, 3 had ALL (1Ph+), 1 had biphenotypic, and 1 had extramedullary (bladder) AML. Unfavorable AML karyotype was noted in 26, intermediate-risk in 7. There was no association between survival from AL and number of prior CLL regimens or karyotype. Expression of CD7 on blasts was associated with shorter survival. Among MDS cases, all IPSS were represented; karyotype was unfavorable in 36, intermediate in 6, and favorable in 12 patients; 10 experienced transformation to AML. Shorter survival from MDS correlated with higher-risk IPSS, poor-risk karyotype, and increased number of prior CLL treatments. Overall, outcomes for patients with CLL subsequently diagnosed with AL or MDS were poor; AL/MDS occurred without prior CLL treatment. Effective therapies for these patients are desperately needed.

This study aimed to assess how the ischemic core measured by perfusion computed tomography (CTP) was affected by the delay and dispersion effect. Ischemic stroke patients having CTP performed within 6 hours of onset were included. The CTP data were processed twice, generating standard cerebral blood flow (sCBF) and delay- and dispersion-corrected CBF (ddCBF), respectively. Ischemic core measured by the sCBF and ddCBF was then compared at the relative threshold <30% of normal tissue. Two references for ischemic core were used: acute diffusion-weighted imaging or 24-hour diffusion-weighted imaging in patients with complete recanalization. Difference of core volume between CTP and diffusion-weighted imaging was estimated by Mann-Whitney U test and limits of agreement. Patients were also classified into favorable and unfavorable CTP patterns. The imaging pattern classification by sCBF and ddCBF was compared by the χ 2 test; their respective ability to predict good clinical outcome (3-month modified Rankin Scale score) was tested in logistic regression. Fifty-five patients were included in this study. Median sCBF ischemic core volume was 38.5 mL (12.4-61.9 mL), much larger than the median core volume of 17.2 mL measured by ddCBF (interquartile range, 5.5-38.8; P <0.001). Moreover, compared with sCBF <30%, ddCBF <30% measured the ischemic core much closer to diffusion-weighted imaging core references, with the mean volume difference of -0.1 mL (95% limits of agreement, -25.4 to 25.2; P =0.97) and 16.7 mL (95% limits of agreement, -21.7 to 55.2; P <0.001), respectively. Imaging patterns defined by sCBF showed a difference to that defined by ddCBF ( P <0.001), with 12 patients classified as favorable imaging patterns by ddCBF but as unfavorable by sCBF. The favorable imaging pattern classified by ddCBF, compared with sCBF classification, had higher predictive power for good clinical outcome (odds ratio, 7.8 [2-30.5] and 3.1 [0.9-11], respectively). Delay and dispersion correction increases the accuracy of ischemic core measurement on CTP. © 2018 American Heart Association, Inc.

Clinicopathologic and prognostic significance of C-reactive protein/albumin ratio in patients with solid tumors: an updated systemic review and meta-analysis.

C-reactive protein/albumin ratio (CAR) was originally used as a novel inflammation-based prognostic score in predicting outcomes in septic patients. Recently, more and more studies have reported the prognostic value of pretreatment CAR in solid tumors. However, the results remain controversial rather than conclusive. We conducted a meta-analysis based on 24 studies with 10203 patients to explore the relationship between CAR and survival outcomes in patients with solid tumors. The correlation between CAR and clinicopathological parameters was also assessed. Hazard ratio (HR) or odds ratio (OR) with its 95% confidence interval (CI) was applied to be the effect size estimate. The overall results showed that elevated CAR was associated with shorter overall survival (OS) (including 23 studies and 10067 patients) and poorer disease-free survival (DFS) (including 6 studies and 2904 patients). Significant associations between high CAR level and poor OS were also found in the subgroup analyses of study region, cancer type, primary treatment, clinical stage, cut-off selection, sample size, and cut-off value. Moreover, subgroup analyses demonstrated that study region, primary treatment, clinical stage, sample size, and cut-off value did not alter the prognostic value of CAR for DFS. Furthermore, elevated CAR was correlated with certain phenotypes of tumor aggressiveness, such as poor histological grade, serious clinical stage, advanced tumor depth, positive lymph node metastasis, and positive distant metastasis. Together, our meta-analysis suggests that elevated level of serum CAR predicts worse survival and unfavorable clinical characteristics in cancer patients, and CAR may serve as an effective prognostic factor for solid tumors.

Evaluation of Genotypic and Phenotypic Protease Virulence Tests for Dichelobacter nodosus Infection in Sheep

ABSTRACT Dichelobacter nodosus is a fastidious, strictly anaerobic bacterium, an obligate parasite of the ruminant hoof, and the essential causative agent of virulent ovine footrot. The clinical disease results from a complex interplay between the pathogen, the environment, and the host. Sheep flocks diagnosed with virulent but not benign footrot in Australia may be quarantined and required to undergo a compulsory eradication program, with costs met by the farmer. Virulence of D. nodosus at least partially depends on the elaboration of a protease encoded by aprV2 and manifests as elastase activity. Laboratory virulence tests are used to assist diagnosis because clinical differentiation of virulent and benign footrot can be challenging during the early stages of disease or when the disease is not fully expressed due to unfavorable pasture conditions. Using samples collected from foot lesions from 960 sheep from 40 flocks in four different geographic regions, we evaluated the analytical characteristics of qPCR tests for the protease gene alleles aprV2 and aprB2, and compared these with results from phenotypic protease (elastase and gelatin gel) tests. There was a low level of agreement between clinical diagnosis and quantitative PCR (qPCR) test outcomes at both the flock and sample levels and poor agreement between qPCR test outcomes and the results of phenotypic virulence tests. The diagnostic specificity of the qPCR test was low at both the flock and individual swab levels (31.3% and 18.8%, respectively). By contrast, agreement between the elastase test and clinical diagnosis was high at both the flock level (diagnostic sensitivity [DSe], 100%; diagnostic specificity [DSp], 78.6%) and the isolate level (DSe, 69.5%; DSp, 80.5%).

Virulence of D. nodosus at least partially depends on the elaboration of a protease encoded by aprV2 and manifests as elastase activity. Laboratory virulence tests are used to assist diagnosis because clinical differentiation of virulent and benign footrot can be challenging during the early stages of disease or when the disease is not fully expressed due to unfavorable pasture conditions. Using samples collected from foot lesions from 960 sheep from 40 flocks in four different geographic regions, we evaluated the analytical characteristics of qPCR tests for the protease gene alleles aprV2 and aprB2 , and compared these with results from phenotypic protease (elastase and gelatin gel) tests. There was a low level of agreement between clinical diagnosis and quantitative PCR (qPCR) test outcomes at both the flock and sample levels and poor agreement between qPCR test outcomes and the results of phenotypic virulence tests. The diagnostic specificity of the qPCR test was low at both the flock and individual swab levels (31.3% and 18.8%, respectively). By contrast, agreement between the elastase test and clinical diagnosis was high at both the flock level (diagnostic sensitivity [DSe], 100%; diagnostic specificity [DSp], 78.6%) and the isolate level (DSe, 69.5%; DSp, 80.5%).

Results of concurrent radio-chemotherapy for the treatment of head and neck squamous cell carcinoma in everyday clinical practice with special reference to early mortality

PubMed Central

2013-01-01

Background Randomized controlled trials have established concurrent chemo-radiotherapy as the preferred treatment option for inoperable local-regionally advanced head and neck squamous cell carcinomas (HNSCCs). Because many patients have multiple co-morbidities and would not fulfill the eligibility criteria of clinical trials, the results need to be re-evaluated in daily clinical practice with special reference to early mortality. Methods 167 consecutive patients with HNSCC who received concurrent chemo-radiotherapy at the Basel University Hospital between 1988 and 2006 were analyzed retrospectively with a special focus on early deaths and risk factors for an unfavorable outcome. Results In our cohort, the 3- and 5-year overall survival rates were 54% and 47%, respectively. The therapy was associated with relevant toxicity and an early mortality rate of 5.4%. Patients dying early were analyzed individually for the cause of death. Patients with elevated white blood cell counts (HR: 2.66 p = 0,016) and vascular co-morbidities (HR: 5.3, p = 0,047) showed significantly worse survival rates. The same factors were associated with a trend toward increased treatment-related mortality. The 3-year survival rate improved from approximately 43% for patients treated before the year 2000 to 65% for patients treated after the year 2000 (Fisher’s exact test p = 0.01). Conclusions Although many patients who received concurrent chemo-radiotherapy would not have qualified for clinical trials, the outcome was favorable and has significantly improved in recent years. However the early mortality was slightly worse than what is described in the literature. PMID:24373220

OBJECTIVE Spinal dural arteriovenous fistulas (dAVFs) are rare vascular abnormalities caused by arteriovenous shunting. They often form at the dural root sleeve between a radicular feeding artery and draining medullary vein causing venous congestion and edema, decreased perfusion, and ischemia of the spinal cord. Treatment consists of either surgical ligation of the draining vein or selective embolization via an endovascular approach. There is a paucity of data on which modality provides more durable and effective outcomes. METHODS The authors performed a retrospective review of a prospectively maintained database by the senior author to assess clinical outcomes in patients undergoing surgical treatment of spinal dAVFs. Preoperative and postoperative motor and Aminoff-Logue Scale (ALS) scores were collected. RESULTS A total of 41 patients with 44 spinal dAVFs were identified, with a mean patient age of 64 years. The mean symptom duration was 14 months, with weakness (82%), urinary symptoms (47%), and sensory symptoms (29%) at presentation. The fistula locations were as follows: 30 thoracic, 9 lumbar, 3 sacral, and 2 cervical. Five patients had normal motor and ALS scores at presentation. Among the remaining 36 patients with motor deficits or abnormal gait and micturition at presentation, 78% experienced an improvement while the remaining 22% continued to be stable. There was a trend toward improved outcomes in patients with shorter symptom duration; mean symptom duration among patients with clinical improvement was 13 months compared with 22 months among those without improvement. Additionally, rates of improvement were higher for lower thoracic and lumbosacral dAVFs (85% and 83%) compared with those in the upper thoracic spine (57%). No patient developed recurrent fistulas or worsening neurological deficits. CONCLUSIONS Surgery is associated with excellent outcomes in the treatment of spinal dAVFs. Early diagnosis and treatment are critical, with a trend toward improved outcomes. No patient in this study had fistula recurrence or worsening of symptoms. Among patients with abnormal motor or ALS scores, 78% improved after surgery. Therapeutic embolization is an option for some lesions, but for cases with unfavorable anatomy where embolization is not feasible, surgery is a safe option associated with high success.

Tibiotalocalcaneal (TTC) fusion using a retrograde intramedullary (IM) nail is an effective salvage option for terminal-stage hindfoot problems. However, as many patients who receive TTC fusion bear unfavorable medical comorbidities, the risk of nonunion, infection and other complications increases. This study was performed to identify the factors influencing outcomes after TTC fusion using a retrograde IM nail. Between September 2008 and February 2012, 34 consecutive patients received TTC fusion using a retrograde IM nail for limb salvage. All patients had a minimum follow-up of two years. Throughout follow-up, standard ankle radiography was performed along with clinical outcome assessment using a visual analog scale (VAS) for pain, the American Orthopaedic Foot and Ankle Society Ankle-Hind Foot Scale (AOFAS A/H scale) and the Foot and Ankle Outcome Score (FAOS). For the retrospective analysis, demographic factors, preoperative medical status, laboratory markers, and etiology were comprehensively reviewed using medical records. The success of the index operation was determined using clinical and radiological outcomes. Finally, the effect of each factor on failure after the operation was analyzed using univariate logistic regression. In a mean of seven months, 82% (28/34) achieved union, as evaluated by standard radiography. All clinical outcome parameters improved significantly after the operation, including VAS, AOFAS A/H scale, and FAOS (P<0.001). At the last follow-up, five cases of nonunion with less than AOFAS A/H scale of 80 and two cases of below knee amputation due to uncontrolled infection were determined to be failures. None of the factors (etiology, demographics, laboratory markers and medical status) significantly influenced failures. However, uncontrolled DM significantly increased the failure rate with an odds ratio of 10 (P=0.029). TTC fusion with a retrograde intramedullary nail is a successful treatment for complicated hindfoot problems such as traumatic osteoarthritis, Charcot arthropathy and failed TAA. However, it should be used judiciously in patients with uncontrolled DM, as the risk of failure increases. Retrospective cohort study. Copyright © 2017 European Foot and Ankle Society.

Bacterial meningitis is associated with significant morbidity and mortality despite advances in medical care. The main objective of this study was to assess the association of adjunctive dexamethasone treatment with discharge outcome of patients treated as bacterial meningitis in low income setting. A retrospective study was conducted at four teaching hospitals across Ethiopia. Patients of age 14 years and older treated as cases of bacterial meningitis between January 1, 2011 and April 30, 2015 were included in this study. Information regarding sociodemographic data, clinical presentations, laboratory data, treatments given and status at hospital discharge were retrieved from patients' medical records using a structured questionnaire. Predefined outcome variables at discharge were analysed using descriptive statistics. Multivariable logistic regression was used to identify factors independently associated with poor outcome. A total of 425 patients treated with the presumptive clinical diagnosis of bacterial meningitis were included in this study (lumbar puncture done in 56 %; only 19 % had CSF findings compatible with bacterial meningitis, and only 3 % had proven etiology). The overall in hospital mortality rate was 20.2 %. Impaired consciousness, aspiration pneumonia, and cranial nerve palsy at admission were independently associated with increased mortality. Adjuvant dexamethasone, which was used in 50.4 % of patients, was associated with increased in-hospital mortality (AOR = 3.38; 95 % CI 1.87-6.12, p < 0.001) and low Glasgow outcome scale (GOS) at discharge (AOR = 4.46 (95 % CI 1.98-10.08). This association between dexamethasone and unfavorable outcome was found to be more pronounced in suspected but unproven cases and in those without CSF alterations compatible with bacterial meningitis. Most patients treated for suspected bacterial meningitis did not receive proper diagnostic workup. Adjuvant dexamethasone use in clinically suspected but unproven cases of bacterial meningitis was associated with an increased mortality and poor discharge GOS. These findings show that there are potential deleterious effects in unconfirmed cases in this setting. Physicians practising under such circumstances should thus abide with the current recommendation and defer the use of adjuvant corticosteroid in suspected cases of bacterial meningitis.

The objectives of this study were to examine differences in nurse engagement in shared governance across hospitals and to determine the relationship between nurse engagement and patient and nurse outcomes. There is little empirical evidence examining the relationship between shared governance and patient outcomes. A secondary analysis of linked cross-sectional data was conducted using nurse, hospital, and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey data. Engagement varied widely across hospitals. In hospitals with greater levels of engagement, nurses were significantly less likely to report unfavorable job outcomes and poor ratings of quality and safety. Higher levels of nurse engagement were associated with higher HCAHPS scores. A professional practice environment that incorporates shared governance may serve as a valuable intervention for organizations to promote optimal patient and nurse outcomes.

To compare grating (resolution) visual acuity at 6 years of age in eyes that received early treatment (ET) for high-risk prethreshold retinopathy of prematurity (ROP) with that in eyes that underwent conventional management (CM). In a randomized clinical trial, infants with bilateral, high-risk prethreshold ROP (n = 317) had one eye undergo ET and the other eye undergo CM, with treatment only if ROP progressed to threshold severity. For asymmetric cases (n = 84), the high-risk prethreshold eye was randomized to ET or CM. Grating visual acuity measured at 6 years of age by masked testers using Teller acuity cards. Monocular grating acuity results were obtained from 317 of 370 surviving children (85.6%). Analysis of grating acuity results for all study participants with high-risk prethreshold ROP showed no statistically significant overall benefit of ET (18.1% vs 22.8% unfavorable outcomes; P = .08). When the 6-year grating acuity results were analyzed according to a clinical algorithm (high-risk types 1 and 2 prethreshold ROP), a benefit was seen in type 1 eyes (16.4% vs 25.2%; P = .004) undergoing ET, but not in type 2 eyes (21.3% vs 15.9%; P = .29). Early treatment of eyes with type 1 ROP improves grating acuity outcomes, but ET for eyes with type 2 ROP does not. APPLICATION TO CLINICAL MEDICINE: Type 1 eyes should be treated early; however, based on acuity results at 6 years of age, type 2 eyes should be cautiously monitored for progression to type 1 ROP.

To determine the role of intracranial pressure (ICP) monitoring in management of patients with severe traumatic brain injury (TBI) admitted to a large level I trauma center in Southern Iran. This was a cohort study performed during a 2-year period in a level I trauma center in Southern Iran including all adult patients (>16 years) with severe TBI (Glasgow Coma Scale [GCS] score, 3-8) who underwent ICP monitoring through ventriculostomy. The management was based on the recorded ICP values with threshold of 20 mm Hg. Decompressive craniectomy was performed in patients with intractable intracranial hypertension (persistent ICP ≥25 mm Hg). In unresponsive patients, barbiturate coma was induced. Patients were followed for 6 months and Glasgow Outcome Scale Extended was recorded. The determinants of favorable and unfavorable outcome were also determined. Overall, we included 248 patients with mean age of 34.6 ± 16.6 years, among whom there were 216 men (87.1%) and 32 women (12.9%). Eighty-five patients (34.2%) had favorable and 163 (65.8%) unfavorable outcomes. Those with favorable outcome had significantly lower age (P = 0.004), higher GCS score on admission (P < 0.001), lower Rotterdam score (P = 0.035), fewer episodes of intracranial hypertension (P < 0.001), and lower maximum recorded ICP (P = 0.041). These factors remained statistically significant after elimination of confounders by multivariate logistic regression model. Age, GCS score on admission, Rotterdam score, intracranial hypertension, and maximum recorded ICP are important determinants of outcome in patients with severe TBI. ICP monitoring assisted us in targeted therapy and management of patients with severe TBI. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Low tri-iodothyronine syndrome is associated with worse prognosis of severely ill patients. We investigated the association of thyroid hormone levels with discharge outcomes and 5-year mortality in primary brain tumor patients. Methods From January, 2010 until September, 2011, 230 patients (70% women) before brain tumor surgery were evaluated for cognitive (Mini mental State Examination; MMSE) and functional (Barthel index; BI) status, and thyroid function profile. The Low triiodothyronine syndrome was defined as triiodothyronine concentration below the reference range. Unfavorable discharge outcomes were Glasgow outcome scale score of ≤3. Follow-up continued until November, 2015. Results Seventy-four percent of patients had Low triiodothyronine syndrome. Lower total tri-iodothyronine concentrations were associated with lower MMSE (p=.013) and BI (p=.023) scores independent of age, gender and histological diagnosis. Preoperative Low tri-iodothyronine syndrome increased risk for unfavorable discharge outcomes adjusting for age, gender and histological diagnosis (OR=2.944, 95%CI [1.314-6.597], p=.009). In all patients, lower tri-iodothyronine concentrations were associated with greater mortality risk (p≤.038) adjusting for age, gender, extent of resection, adjuvant treatment and histological diagnosis. The Low tri-iodothyronine syndrome was associated with greater 5-year mortality for glioma patients (HR=2.197; 95%CI [1.160-4.163], p=.016) and with shorter survival (249 [260] vs. 352 [399] days; p=.029) of high grade glioma patients independent of age, gender, extent of resection and adjuvant treatment. Conclusions The Low tri-iodothyronine syndrome is common in brain tumor patients and is associated with poor functional and cognitive status, and with worse discharge outcomes. The Low tri-iodothyronine syndrome is associated with shorter survival of glioma patients. PMID:28055959

Data on long-term outcomes of percutaneous mitral valvuloplasty (PMV) are still scarce. In addition, the persistence of pulmonary hypertension (PH) after PMV is a complication for which mechanisms and prognostic implications are unclear. Our aims were (1) to report the long-term outcomes of patients with rheumatic mitral stenosis treated with PMV; (2) to determine the risk factors for long-term poor outcomes; and (3) to analyze the prevalence and predictors of persistent PH. We prospectively enrolled 532 patients who underwent PMV from 1987 to 2011 at 2 hospitals. The following end points were assessed after PMV: all-cause mortality, mitral reintervention, a composite end point of all-cause mortality and mitral reintervention, and PH persistence. Survival status was available for 97% patients; the median follow-up was 10 years (interquartile range 4 to 18 years). Procedural success was achieved in 85% patients. During the follow-up, 21% patients died and 27% required mitral reintervention. Before PMV, 74% patients had PH that persisted after PMV in 45% of patients (p <0.001). Unfavorable valve anatomy (Wilkins score >8) and post-PMV mean pulmonary arterial pressure (PAP) were independent predictors of all-cause mortality, mitral reintervention, and the composite end point. Post-PMV mean PAP was significantly correlated with a mitral valve area (MVA) <2.5 cm(2) (p <0.001); in addition, on the echocardiographic follow-up, MVA was an independent predictor of systolic PAP (p <0.001). In conclusion, PMV represents an advantageous therapeutic option for patients with mitral stenosis in terms of long-term outcomes. Unfavorable valve anatomy and persistent PH were the most important predictors of long-term outcomes. The persistence of PH is associated with the MVA obtained after PMV.

How physicians convey information about hepatitis C virus (HCV) impacts patients' perceptions of treatment outcomes and informed therapy decisions. However, HCV patients reported difficulties communicating with their physicians in a recent study. Another study showed that 45% of patients did not understand projected response rates conveyed by providers, and patients with unfavorable projected treatment outcomes were more likely to lack understanding. This article analyzes naturally occurring patient-provider interactions to evaluate physicians' use of the word 'cure', and framing of HCV response as optimistic, pessimistic, or neutral, to suggest possible reasons why patients with unfavorable projected sustained virologic response rates might perceive their odds as more favorable than they are. Gastroenterologists, allied health professionals, and HCV patients were video and audio-recorded during regular scheduled visits. Recordings were transcribed and analyzed using validated sociolinguistic techniques. Sixty-three percent of physicians used the word 'cure' in 38% of visits involving response discussions. 'Cure' most frequently meant 'absolute cure' and occurred more commonly in visits conducted before therapy initiation, and with patients having favorable genotypes. Physicians hedged the meaning of 'cure' in 29% of visits. Moreover, 69.5% of response-related utterances were framed optimistically. HCV dialogs are characterized by the prevalence of 'cure' and optimistic framing. These positive language attributes could potentially contribute to the misunderstanding regarding the projected response rates. During treatment outcome discussions, the physicians should attempt to (1) operate using the same definition of the therapy outcome as the patient, (2) balance medically accurate information with patient comprehension, and (3) consider possible consequences of discussing treatment options on the basis of message framing.

To overcome radioresistance for patients with unfavorable prostate cancer, a prospective trial of pelvic external beam irradiation (EBRT) interdigitated with dose-escalating conformal high-dose-rate (HDR) prostate brachytherapy was performed. Between November 1991 and August 2000, 207 patients were treated with 46 Gy pelvic EBRT and increasing HDR brachytherapy boost doses (5.50-11.5 Gy/fraction) during 5 weeks. The eligibility criteria were pretreatment prostate-specific antigen level >or=10.0 ng/mL, Gleason score >or=7, or clinical Stage T2b or higher. Patients were divided into 2 dose levels, low-dose biologically effective dose <93 Gy (58 patients) and high-dose biologically effective dose >93 Gy (149 patients). No patient received hormones. We used the American Society for Therapeutic Radiology and Oncology definition for biochemical failure. The median age was 69 years. The mean follow-up for the group was 4.4 years, and for the low and high-dose levels, it was 7.0 and 3.4 years, respectively. The actuarial 5-year biochemical control rate was 74%, and the overall, cause-specific, and disease-free survival rate was 92%, 98%, and 68%, respectively. The 5-year biochemical control rate for the low-dose group was 52%; the rate for the high-dose group was 87% (p <0.001). Improvement occurred in the cause-specific survival in favor of the brachytherapy high-dose level (p = 0.014). On multivariate analysis, a low-dose level, higher Gleason score, and higher nadir value were associated with increased biochemical failure. The Radiation Therapy Oncology Group Grade 3 gastrointestinal/genitourinary complications ranged from 0.5% to 9%. The actuarial 5-year impotency rate was 51%. Pelvic EBRT interdigitated with transrectal ultrasound-guided real-time conformal HDR prostate brachytherapy boost is both a precise dose delivery system and a very effective treatment for unfavorable prostate cancer. We demonstrated an incremental beneficial effect on biochemical control and cause-specific survival with higher doses. These results, coupled with the low risk of complications, the advantage of not being radioactive after implantation, and the real-time interactive planning, define a new standard for treatment.

Cerebrovascular autoregulation (CA) is an important hemodynamic mechanism that protects the brain against inappropriate fluctuations in cerebral blood flow in the face of changing cerebral perfusion pressure. Temporal CA failure is associated with worse outcomes in various acute neurological diseases. An integrative approach is presently used according to the existing paradigm for the association of series of temporal CA impairments with the outcomes of patients with traumatic brain injury (TBI). To explore the influence of the duration of CA impairment events on severe TBI patient outcomes. Patient age was also included in the analysis of the prospectively collected clinical data. CA monitoring included 33 prospective severe TBI patients. The pressure reactivity index [PRx(t)] was continuously monitored to collect information on the dynamics of CA status and to analyze associations between the duration of the longest CA impairment event and patient outcomes. The Glasgow outcome scale and the duration of the longest CA impairment were negatively correlated. The duration of autoregulation impairment significantly correlated with worse outcomes. Multidimensional representation of Glasgow outcome scale plots showed that better outcomes were obtained for younger patients (age < 47 years) and those whose longest CA impairment event was shorter than 40 minutes if PRx(t) was above 0.7 in the CA impairment event. Unfavorable outcomes for TBI patients are more significantly associated with the duration of the single longest CA impairment episode at a high PRx(t) value, rather than with averaged PRx(t) values or the average time of all CA impairment episodes.

Asian-American men with prostate cancer have been reported to present with higher grade and later stage disease than white American men. However, Asian-American men comprise a heterogeneous population with distinct health outcomes. We compared prostate cancer risk profiles among the diverse racial and ethnic groups in California. We used data from the California Cancer Registry on 90,845 nonHispanic white, nonHispanic black and Asian-American men diagnosed with prostate cancer between 2004 and 2010. Patients were categorized into low, intermediate and high risk groups based on clinical stage, Gleason score and prostate specific antigen at diagnosis. Using polytomous logistic regression we estimated adjusted ORs for the association of race/ethnicity and nativity with risk group. In addition to the nonHispanic black population, 6 Asian-American groups (United States born Chinese, foreign born Chinese, United States born Japanese, foreign born Japanese, foreign born Filipino and foreign born Vietnamese) were more likely to have an unfavorable risk profile compared to nonHispanic white men. The OR for high vs intermediate risk disease ranged from 1.23 (95% CI 1.02-1.49) for United States born Japanese men to 1.45 (95% CI 1.31-1.60) for foreign born Filipino men. These associations appeared to be driven by higher grade and prostate specific antigen rather than by advanced clinical stage at diagnosis. In this large, ethnically diverse, population based cohort Asian-American men were more likely to have an unfavorable risk profile at diagnosis. This association varied by racial/ethnic group and nativity, and was not attributable to later stage at diagnosis. This suggests that Asian men may have biological differences that predispose to more severe disease. Copyright © 2014 American Urological Association Education and Research, Inc.

Although lymphadenectomy is currently accepted as most accurate and reliable staging procedure for lymph node metastases, its therapeutic benefit in renal cell carcinoma (RCC) still remains controversial. Although the new, targeted therapy paradigms have changed the treatment of patients with advanced RCC and offer prolonged survival, cure is extremely uncommon in the absence of surgical resections. In this paper, the current role of metastasectomy is reviewed. Review the available literature concerning the role of retroperitoneal lymph node dissection and metastasectomy in outcome of oligometastatic RCC. A PubMed search was conducted to identify original articles, review articles, and editorials addressing the role of retroperitoneal lymph node dissection and metastasectomy in outcome of oligometastatic RCC. Keywords included renal tumors, renal cell cancer, kidney cancer, lymphadenectomy, metastasectomy, and oligometastases. While there is no randomized study available, recent large observational studies have better defined the prognosis of patients with metastatic RCC with or without metastasectomy and RPLND. To date, the available evidence suggests that RPLND and metastasectomy may be beneficial when technically feasible in patients with locally advanced (unfavorable clinical and pathologic characteristics) and oligometastatic disease. A proportion of patients will achieve long-term survival with aggressive surgical resection.

This prospective consecutive double-blinded randomized study investigated the effect of prostacyclin on pressure reactivity (PR) in severe traumatic brain injured patients. Other aims were to describe PR over time and its relation to outcome. Blunt head trauma patients, Glasgow coma scale ≤8, age 15-70 years were included and randomized to prostacyclin treatment (n = 23) or placebo (n = 25). Outcome was assessed using the extended Glasgow outcome scale (GOSE) at 3 months. PR was calculated as the regression coefficient between the hourly mean values of ICP versus MAP. Pressure active/stable was defined as PR ≤0. Mean PR over 96 h (PRtot) was 0.077 ± 0.168, in the prostacyclin group 0.030 ± 0.153 and in the placebo group 0.120 ± 0.173 (p < 0.02). There was a larger portion of pressure-active/stable patients in the prostacyclin group than in the placebo group (p < 0.05). Intra-individual changes over time were common. PRtot correlated negatively with GOSE score (p < 0.04). PRtot was 0.117 ± 0.182 in the unfavorable (GOSE 1-4) and 0.029 ± 0.140 in the favorable outcome group (GOSE 5-8). Area under the curve for prediction of death (ROC) was 0.742 and for favorable outcome 0.628. Prostacyclin influenced the PR in a direction of increased pressure stability and a lower PRtot was associated with improved outcome. The individual PR varied substantially over time. The predictive value of PRtot for outcome was not solid enough to be used in the clinical situation.

Hemolytic uremic syndrome related to Shiga-toxin-secreting Escherichia coli infection (STEC-HUS) remains a common cause of acute kidney injury in young children. No specific treatment has been validated for this severe disease. Recently, experimental studies highlight the potential role of complement in STEC-HUS pathophysiology. Eculizumab (EC), a monoclonal antibody against terminal complement complex, has been used in severe STEC-HUS patients, mostly during the 2011 German outbreak, with conflicting results. On behalf of the French Society of Pediatric Nephrology, we retrospectively studied 33 children from 15 centers treated with EC for severe STEC-HUS. Indication for EC was neurologic involvement in 20 patients, cardiac and neurologic involvement in 8, cardiac involvement in 2, and digestive involvement in 3. Based on medical status at last follow-up, patients were divided into two groups: favorable (n = 15) and unfavorable outcomes (n = 18). Among patients with favorable outcome, 11/14 patients (79%) displayed persistent blockade of complement activity before each EC reinjection. Conversely, in patients with unfavorable outcome, only 9/15 (53%) had persistent blockade (p = n.s.). Among 28 patients presenting neurological symptoms, 19 had favorable neurological outcome including 17 with prompt recovery following first EC injection. Only two adverse effects potentially related to EC treatment were reported. Taken together, these results may support EC use in severe STEC-HUS patients, especially those presenting severe neurological symptoms. The study, however, is limited by absence of a control group and use of multiple therapeutic interventions in treatment groups. Thus, prospective, controlled trials should be undertaken.

The randomized trials showed improved outcome and reduced mortality in malignant middle cerebral artery (MMCA) undergoing Decompressive hemicraniectomy (DHC) within 48 hours of stroke onset. Despite high prevalence of stroke, especially in younger individuals, high and short-term mortality from stroke in South Asian and Middle East, there is little published data on DHC in patients with MMCA stroke. This is a retrospective, multicenter cross-sectional study to measure outcome following DHC using the modified Rankin Scale (mRS) and dichotomized as favorable (mRS ≤ 4) or unfavorable (mRS > 4), at 3 months. In total, 137 patients underwent DHC. At 90 days, mortality was 16.8%; 61.3% of patients survived with an mRS of 4 or less and 38.7% had an mRS greater than 4. Age (55 years), diabetes (P = .004), hypertension (P = .021), pupillary abnormality (P = .048), uncal herniation (P = .007), temporal lobe involvement (P = .016), additional infarction (MCA + anterior cerebral artery, posterior cerebral artery) (P = .001), and infarction growth rates (P = .025) were significantly higher in patients with unfavorable prognosis in univariate analysis. Multivariate analysis showed age, additional infarction, septum pellucidum deviation greater than 1 cm, and uncal herniation to be associated with a significantly poor prognosis. Time to surgery had no impact on outcome (P = .109). Similar to the results of the studies from the West, DHC Improves functional outcome in predominantly South Asian patients with MMCA Stroke.

Estabrook, Ryne; Grimm, Kevin J.; Bowles, Ryan P.

2012-01-01

Recent research has seen intraindividual variability (IIV) become a useful technique to incorporate trial-to-trial variability into many types of psychological studies. IIV as measured by individual standard deviations (ISDs) has shown unique prediction to several types of positive and negative outcomes (Ram, Rabbit, Stollery, & Nesselroade, 2005). One unanswered question regarding measuring intraindividual variability is its reliability and the conditions under which optimal reliability is achieved. Monte Carlo simulation studies were conducted to determine the reliability of the ISD compared to the intraindividual mean. The results indicate that ISDs generally have poor reliability and are sensitive to insufficient measurement occasions, poor test reliability, and unfavorable amounts and distributions of variability in the population. Secondary analysis of psychological data shows that use of individual standard deviations in unfavorable conditions leads to a marked reduction in statistical power, although careful adherence to underlying statistical assumptions allows their use as a basic research tool.

People living nowadays with HIV and AIDS may be treated effectively regarding virus replication and immunology. However, non-AIDS-defining cancer is of growing relevance due to high incidence and unfavorable outcome. The aim of this review is to summarize current knowledge on gastrointestinal (GI) carcinoma. Although literature on GI cancer is rare, an increased incidence of esophageal, gastric, pancreatic, hepatocellular, and colorectal carcinoma has been demonstrated. However, there are only few reports on therapy strategies and outcome, so that, despite increased occurrence of many GI carcinomas, only little is known about individualized treatment options and outcome in HIV-positive patients. More efforts have to be undertaken to close this gap. © 2017 S. Karger GmbH, Freiburg.

Objective To determine the predictive value of S100b and brain natriuretic peptide (BNP) to accurately and quickly determine discharge prognosis after primary supratentorial intracerebral hemorrhage (ICH). Methods After IRB approval and informed consent, blood samples were obtained and analyzed from 28 adult patients consecutively admitted to the neuroscience intensive care unit with computed tomography-proven supratentorial ICH from June 2003 and December 2004 within the first 24 h after symptom onset for S100b and BNP. Functional outcomes on discharge were dichotomized to favorable (mRS<3) or unfavorable. Results BNP (a neurohormone) and S100b (a marker of glial activation) were found to be independently highly predictive of functional neurological outcome at the time of discharge as measured by modified Rankin Score (BNP:p<0.01, r=0.46; S100b: p<0.01, r=0.42) and Barthel Index (BNP:p<0.01, r=0.54; s100b:p<0.01, r=0.50). Although inclusion of either biomarker produced additive value when included with traditional clinical prognostic variables, such as the ICH Score (Barthel index: p<0.01, r=0.66; mRS:p<0.01, r=0.96), little predictive power is added with inclusion of both biomarkers in a regression model for neurological outcome. Conclusions Serum S100b and BNP levels in the first 24 h after injury accurately predict neurological function at discharge after supratentorial ICH. PMID:19505208

This randomized, controlled trial assessed the effectiveness of comprehensive geriatric assessment (CGA) and subsequent intervention in pre-frail and frail community-dwelling elderly based on the Fried Frailty Criteria (FFC) and the Barthel Index (BI) A total of 310 pre-frail or frail elderly from a single community were identified using the FFC. Of these, 152 were randomly assigned to the intervention group for CGA and appropriate intervention by medication adjustment, exercise instruction, nutrition support, physical rehabilitation, social worker consultation, and specialty referral. Clinical outcome was re-evaluated by the FFC and BI 6 months later. Compared to the control group, the intervention group tended to have a better outcome, with an odds ratio (OR) = 1.19, 95% confidence interval (95% CI) = 0.48-3.04, p = 0.71) and 3.29 (95% CI = 0.65-16.64, p = 0.15), respectively, and were less likely to deteriorate, with an OR = 0.78 (95% CI = 0.34-1.79, p = 0.57) and 0.94 (95% CI = 0.42-2.12, p = 0.88), respectively. Although no significant differences were observed, the CGA and subsequent intervention showed a favorable outcome in frail and pre-frail elderly based on the frailty status and BI. Inability to complete the CGA and poor compliance with the intervention program appear to be the main reasons for unfavorable outcomes. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

To assess regional brain injury on magnetic resonance imaging (MRI) after pediatric cardiac arrest (CA) and to associate regional injury with patient outcome and effects of hypothermia therapy for neuroprotection. We performed a retrospective chart review with prospective imaging analysis. Children between 1 week and 17 years of age who had a brain MRI in the first 2 weeks after CA without other acute brain injury between 2002 and 2008 were included. Brain MRI (1.5 T General Electric, Milwaukee, WI, USA) images were analyzed by 2 blinded neuroradiologists with adjudication; images were visually graded. Brain lobes, basal ganglia, thalamus, brain stem, and cerebellum were analyzed using T1, T2, and diffusion-weighted images (DWI). We examined 28 subjects with median age 1.9 years (IQR 0.4-13.0) and 19 (68 %) males. Increased intensity on T2 in the basal ganglia and restricted diffusion in the brain lobes were associated with unfavorable outcome (all P < 0.05). Therapeutic hypothermia had no effect on regional brain injury. Repeat brain MRI was infrequently performed but demonstrated evolution of lesions. Children with lesions in the basal ganglia on conventional MRI and brain lobes on DWI within the first 2 weeks after CA represent a group with increased risk of poor outcome. These findings may be important for developing neuroprotective strategies based on regional brain injury and for evaluating response to therapy in interventional clinical trials.

Patients with chronic lymphocytic leukemia (CLL) harboring TP53 aberrations (TP53abs; chromosome 17p deletion and/or TP53 mutation) exhibit an unfavorable clinical outcome. Chromosome 8 abnormalities, namely losses of 8p (8p−) and gains of 8q (8q+) have been suggested to aggravate the outcome of patients with TP53abs. However, the reported series were small, thus hindering definitive conclusions. To gain insight into this issue, we assessed a series of 101 CLL patients harboring TP53 disruption. The frequency of 8p− and 8q+ was 14.7% and 17.8% respectively. Both were associated with a significantly (P < 0.05) higher incidence of a complex karyotype (CK, ≥3 abnormalities) detected by chromosome banding analysis (CBA) compared to cases with normal 8p (N-8p) and 8q (N-8q), respectively. In univariate analysis for 10-year overall survival (OS), 8p− (P = 0.002), 8q+ (P = 0.012) and CK (P = 0.009) were associated with shorter OS. However, in multivariate analysis only CK (HR = 2.47, P = 0.027) maintained independent significance, being associated with a dismal outcome regardless of chromosome 8 abnormalities. In conclusion, our results highlight the association of chromosome 8 abnormalities with CK amongst CLL patients with TP53abs, while also revealing that CK can further aggravate the prognosis of this aggressive subgroup.

AIM To compare the outcome between patients with jejunoileal atresia (JIA) associated with cystic meconium peritonitis (CMP) and patients with isolated JIA (JIA without CMP). METHODS A retrospective study was conducted for all neonates with JIA operated in our institute from January 2005 to January 2016. Demographics including the gestation age, sex, birth weight, age at operation, the presence of associated syndrome was recorded. Clinical outcome including the type of operation performed, operative time, the need for reoperation and mortality were studied. The demographics and the outcome between the 2 groups were compared. RESULTS During the study period, 53 neonates had JIA underwent operation in our institute. Seventeen neonates (32%) were associated with CMP. There was no statistical difference on the demographics in the two groups. Patients with CMP had earlier operation than patients with isolated JIA (mean 1.4 d vs 3 d, P = 0.038). Primary anastomosis was performed in 16 patients (94%) with CMP and 30 patients (83%) with isolated JIA (P = 0.269). Patients with CMP had longer operation (mean 190 min vs 154 min, P = 0.004). There were no statistical difference the need for reoperation (3 vs 6, P = 0.606) and mortality (2 vs 1, P = 0.269) between the two groups. CONCLUSION Primary intestinal anastomosis can be performed in 94% of patients with JIA associated with CMP. Although patients with CMP had longer operative time, the mortality and reoperation rates were low and were comparable to patients with isolated JIA. PMID:28224094

Social cognitive function, involved in the perception, processing, and interpretation of social information, has been shown to be crucial for successful communication and interpersonal relationships, thereby significantly impacting mental health, well-being, and quality of life. In this regard, assessment of social cognition, mainly focusing on four key domains, such as theory of mind (ToM), emotional empathy, and social perception and behavior, has been increasingly evaluated in clinical settings, given the potential implications of impairments of these skills for therapeutic decision-making. With regard to neurodegenerative diseases (NDs), most disorders, characterized by variable disease phenotypes and progression, although similar for the unfavorable prognosis, are associated to impairments of social cognitive function, with consequent negative effects on patients' management. Specifically, in some NDs these deficits may represent core diagnostic criteria, such as for behavioral variant frontotemporal dementia (bvFTD), or may emerge during the disease course as critical aspects, such as for Parkinson's and Alzheimer's diseases. On this background, we aimed to revise the most updated evidence on the neurobiological hypotheses derived from network-based approaches, clinical manifestations, and assessment tools of social cognitive dysfunctions in NDs, also prospecting potential benefits on patients' well-being, quality of life, and outcome derived from potential therapeutic perspectives of these deficits.

Abstract Rationale: Currently, percutaneous catheter drainage (PCD) is regarded as the first-line treatment modality of pyogenic liver abscess. Severe complications associated with PCD were uncommon. Hepatic rupture is an uncommon but life-threatening liver trauma with high mortality. Its management is challenging because a delay in the diagnosis may lead to fatal hemorrhagic shock. To our knowledge, PCD-associated hepatic rupture has never been reported. Patient concerns: We report herein a rare case of PCD-associated hepatic rupture. Its clinical courses and our therapeutic approaches are presented. Moreover, the clinical significance, underlying causes, and current views on severe liver trauma management will be discussed briefly. Diagnoses: A diabetic patient suffering from fever and malaise was diagnosed with a pyogenic liver abscess. PCD was performed because intravenous antibiotics were ineffective. The patient developed a liver rupture following PCD, with clinical and imaging confirmation but without further progression. Interventions: Surgical repair and vascular intervention were both inappropriate. As a result, medical treatments with supportive care were adopted and were found to be effective. Outcomes: The patient's condition improved gradually, with stabilized imaging and laboratory performance. He recovered uneventfully during follow-ups. Lessons: Hepatic rupture should be listed as an extremely rare but severe complication of PCD. Immediate suspicion and effective intervention may avoid an unfavorable consequence. PMID:29480839

Roughness Versus Charge Contributions to Representative Discrete Heterogeneity Underlying Mechanistic Prediction of Colloid Attachment, Detachment and Breakthrough-Elution Behavior Under Environmental Conditions.

NASA Astrophysics Data System (ADS)

Johnson, William; Farnsworth, Anna; Vanness, Kurt; Hilpert, Markus

2017-04-01

The key element of a mechanistic theory to predict colloid attachment in porous media under environmental conditions where colloid-collector repulsion exists (unfavorable conditions for attachment) is representation of the nano-scale surface heterogeneity (herein called discrete heterogeneity) that drives colloid attachment under unfavorable conditions. The observed modes of colloid attachment under unfavorable conditions emerge from simulations that incorporate discrete heterogeneity. Quantitative prediction of attachment (and detachment) requires capturing the sizes, spatial frequencies, and other properties of roughness asperities and charge heterodomains in discrete heterogeneity representations of different surfaces. The fact that a given discrete heterogeneity representation will interact differently with different-sized colloids as well as different ionic strengths for a given sized colloid allows backing out representative discrete heterogeneity via comparison of simulations to experiments performed across a range of colloid size, solution IS, and fluid velocity. This has been achieved on unfavorable smooth surfaces yielding quantitative prediction of attachment, and qualitative prediction of detachment in response to ionic strength or flow perturbations. Extending this treatment to rough surfaces, and representing the contributions of nanoscale roughness as well as charge heterogeneity is a focus of this talk. Another focus of this talk is the upscaling the pore scale simulations to produce contrasting breakthrough-elution behaviors at the continuum (column) scale that are observed, for example, for different-sized colloids, or same-sized colloids under different ionic strength conditions. The outcome of mechanistic pore scale simulations incorporating discrete heterogeneity and subsequent upscaling is that temporal processes such as blocking and ripening will emerge organically from these simulations, since these processes fundamentally stem from the limited sites available for attachment as represented in discrete heterogeneity.

Studies regarding short-term outcomes after percutaneous coronary intervention (PCI) have reported no ethnic differences and data on long-term follow-up is conflicting and sparse. 730 consecutive patients (67% African American) undergoing PCI from January 1999 to December 2000 at a tertiary care center in Detroit, MI, were followed up. End points studied included either all cause mortality collected from Social Security Death Index or first hospital admission after the index procedure due to myocardial infarction(MI), congestive heart failure(CHF), and revascularization (PCI or coronary artery bypass graft surgery). African-Americans undergoing PCI had significant differences in baseline cardiovascular co-morbidity and were more likely to present with acute myocardial infarction than Caucasians. On Kaplan Meier survival analysis and log rank test, each ethnic group had equivalent survival for cumulative end points upto 6-month follow-up, however longer follow-up to 5 year was characterized by lower survival rate in African Americans compared to Caucasians (41% vs. 54%, log rank P 0.01). After adjustment for potential confounders, AA ethnicity (Adjusted HR 1.62, 95% CI 1.01-1.28, P 0.04) remained a predictor of adverse cardiac outcome (Death/MI/CHF) at five-year follow-up (Cox regression propensity adjusted hazard analysis). African American patients undergoing PCI had unfavorable baseline cardiovascular characteristics but comparable short-term outcome compared to whites. However, at 5-year follow-up, African Americans had worse clinical outcome, higher incidence of acute myocardial infarction, congestive heart failure and significantly lower long-term survival.

Objective The objective of this study was to examine differences in nurse engagement in shared governance across hospitals and to determine the relationship between nurse engagement and patient and nurse outcomes. Background There is little empirical evidence examining the relationship between shared governance and patient outcomes. Methods A secondary analysis of linked cross-sectional data was conducted using nurse, hospital, and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey data. Results Engagement varied widely across hospitals. In hospitals with greater levels of engagement, nurses were significantly less likely to report unfavorable job outcomes and poor ratings of quality and safety. Higher levels of nurse engagement were associated with higher HCAHPS scores. Conclusions A professional practice environment that incorporates shared governance may serve as a valuable intervention for organizations to promote optimal patient and nurse outcomes.

The course and clinical predictors of rehospitalization were studied in a large sample of adolescent patients with anorexia nervosa who had been treated at five European sites and been followed-up. Two-hundred and twelve adolescent patients first admitted for in-patient treatment, aged 10-18 (Mean 14.9) years and 94.8% female, were followed-up for an average of 8.3 years after first admission at sites in (former East and West Berlin, Zurich, Sofia, and Bucharest). Clinical history data were collected by use of standardized item-sheets at first admission. Semi-structured interviews including ratings of eating pathology and psychosocial outcome were performed at follow-up. About 44.8% (95/212) of the patients required at least one readmission. Rates of rehospitalization were significantly higher at the Eastern sites (Sofia and Bucharest). Significant predictors of readmission were paternal alcoholism, history of anorexia nervosa in the family, eating disorder in infancy, periodic overactivity, lower weight increase at first admission, and lower BMI at first discharge. In a model of logistic regression analysis, five variables (paternal alcoholism, eating disorder in infancy, periodic overactivity, low weight increase during first admission, and low BMI at first discharge) correctly classified 69% of the participants into cases with single or repeated admissions. Patients with repeated admissions had a less favorable long term outcome and had higher rates of persisting psychopathology at follow-up. Rehospitalization reflects the chronic course in a sizable proportion of adolescent patients with anorexia nervosa. Family psychopathology may have an effect both in terms of genetic vulnerability and environmental stress leading to unfavorable courses. The strong effect of insufficient weight gain during first admission and lower BMI at first discharge emphasizes the importance of adequate interventions. Readmissions carry the risk for later poor psychosocial and psychiatric outcomes.

EARLYDRAIN- outcome after early lumbar CSF-drainage in aneurysmal subarachnoid hemorrhage: study protocol for a randomized controlled trial.

Aneurysmal subarachnoid hemorrhage (SAH) may be complicated by delayed cerebral ischemia, which is a major cause of unfavorable clinical outcome and death in SAH-patients. Delayed cerebral ischemia is presumably related to the development of vasospasm triggered by the presence of blood in the basal cisterns. To date, oral application of the calcium antagonist nimodipine is the only prophylactic treatment for vasospasm recognized under international guidelines.In retrospective trials lumbar drainage of cerebrospinal fluid has been shown to be a safe and feasible measure to remove the blood from the basal cisterns and decrease the incidence of delayed cerebral ischemia and vasospasm in the respective study populations. However, the efficacy of lumbar drainage has not been evaluated prospectively in a randomized controlled trial yet. This is a protocol for a 2-arm randomized controlled trial to compare an intervention group receiving early continuous lumbar CSF-drainage and standard neurointensive care to a control group receiving standard neurointensive care only. Adults suffering from a first aneurysmal subarachnoid hemorrhage whose aneurysm has been secured by means of coiling or clipping are eligible for trial participation. The effect of early CSF drainage (starting < 72 h after securing the aneurysm) will be measured in the following ways: the primary endpoint will be disability after 6 months, assessed by a blinded investigator during a personal visit or standardized telephone interview using the modified Rankin Scale. Secondary endpoints include mortality after 6 months, angiographic vasospasm, transcranial Doppler sonography (TCD) mean flow velocity in both middle cerebral arteries and rate of shunt insertion at 6 months after hospital discharge. Here, we present the study design of a multicenter prospective randomized controlled trial to investigate whether early application of a lumbar drainage improves clinical outcome after aneurysmal subarachnoid hemorrhage.

Mid and long term outcomes of dural arteriovenous fistula endovascular management with Onyx. Experience of a single tertiary center.

The natural history of intracranial dural arteriovenous fistulas (DAVFs) with cortical venous drainage is unfavorable, and treatment is recommended in most cases. Early reports have documented excellent initial clinical and radiographic outcomes after Onyx embolization of DAVFs but little evidence is available regarding the long term durability of this technique. We retrospectively reviewed a database of 63 DAVFs in 53 consecutive patients who underwent Onyx embolization of a DAVF between 2001 and 2012 at our institution. Cognard types I and III were seen most commonly. A total of 72 Onyx embolization procedures were successfully completed during the study period, resulting in complete or near complete occlusion by the end of the study period in 58 (92.1%) DAVFs. For DAVFs in which complete or near complete obliteration was attained, stability of obliteration at 6, 12, 24, and 46 months was 100%, 95.4%, 93.8%, and 92.3%, respectively. DAVF recanalization/regrowth was discovered on delayed follow-up angiography in only five instances in which immediate post-embolization angiography revealed complete obliteration. Complications were seen in seven embolization procedures and included cranial nerve palsies (n=3), embolic infarcts (n=2), intraparenchymal hemorrhage (n=1), and unintentional stent deployment (n=1). Early evidence has indicated that endovascular Onyx embolization is safe and effective at achieving an initial angiographic cure. Results of our series suggest that angiographic and clinical outcomes of Onyx embolization remain relatively stable at mid and long term follow-up. Published by the BMJ Publishing Group Limited.

Approximately 17% of ruptured anterior communicating artery (ACoA) aneurysms were deemed unsuitable for coil embolization during the Barrow Ruptured Aneurysm Trial (BRAT), most commonly due to unfavorable dome-to-neck ratio or small size. To compare patients treated by coil embolization for ruptured ACoA aneurysms during the trial to those treated after the trial to determine whether advances in endovascular techniques have allowed for effective treatment of these lesions. All cases of ruptured ACoA aneurysms treated by endovascular modalities during BRAT (2003-2007) and post-BRAT (2007-2012) were reviewed for patient and aneurysm characteristics, treatment types, and clinical and angiographic outcomes at 3-yr or last follow-up. The BRAT ACoA cohort included 39 patients treated with coiling (excluding those crossed over to clipping). The post-BRAT cohort included 93 patients who were significantly older (mean age, 59.5 vs 52.8 yr, P = .005) than the BRAT cohort; there were no significant cohort differences in sex, Hunt and Hess grade, or mean aneurysm size. The use of balloon remodeling was significantly higher in the post-BRAT cohort (31.2% [29/93] vs 5.1% [2/39], P = .001), as was the proportion of wide-necked aneurysms treated (66.7% [62/93] vs 30.8% [12/39], P < .001). There was no significant difference in clinical outcome or retreatment rate between the 2 cohorts (P = .90 and P = .48, respectively). ACoA lesions thought unamenable to endovascular therapy in an earlier randomized trial are now successfully coiled with increased use of adjunctive techniques, without sacrificing patient outcome or treatment durability.

Purpose: To perform an in-depth temporal analysis of visual acuity (VA) outcomes after proton beam radiation therapy (PBRT) in a large, uniformly treated cohort of uveal melanoma (UM) patients, to determine trends in VA evolution depending on pretreatment and temporally defined posttreatment VA measurements; and to investigate the relevance of specific patient, tumor and dose-volume parameters to posttreatment vision loss. Methods and Materials: Uveal melanoma patients receiving PBRT were identified from a prospectively maintained database. Included patients (n=645) received 56 GyE in 4 fractions, had pretreatment best corrected VA (BCVA) in the affected eye of count fingers (CF) or better, withmore » posttreatment VA assessment at specified post-PBRT time point(s). Patients were grouped according to the pretreatment BCVA into favorable (≥20/40) or unfavorable (20/50-20/400) and poor (CF) strata. Temporal analysis of BCVA changes was described, and univariate and forward stepwise multivariate logistic regression analyses were performed to identify predictors for VA loss. Results: Median VA follow-up was 53 months (range, 3-213 months). At 60-month follow up, among evaluable treated eyes with favorable pretreatment BCVA, 45% retained BCVA ≥20/40, whereas among evaluable treated eyes with initially unfavorable/poor BCVA, 21% had vision ≥20/100. Among those with a favorable initial BCVA, attaining BCVA of ≥20/40 at any posttreatment time point was associated with subsequent maintenance of excellent BCVA. Multivariate analysis identified volume of the macula receiving 28GyE (P<.0001) and optic nerve (P=.0004) as independent dose-volume histogram predictors of 48-month post-PBRT vision loss among initially favorable treated eyes. Conclusions: Approximately half of PBRT-treated UM eyes with excellent pretreatment BCVA assessed at 5 years after treatment will retain excellent long-term vision. 28GyE macula and optic nerve dose-volume histogram parameters allow for rational treatment planning optimization that may lead to improved visual outcomes. The detailed temporal analysis with intermediate as well as long-term functional prognosis, and the relationship of outcomes with clinical and treatment planning parameters, is critical for informed care of UM patients before and after PBRT.« less

Purpose To describe the incidence, risk factors, clinical presentation, causative organisms, and outcomes in patients with endophthalmitis following pars plana vitrectomy (20G and minimally invasive vitrectomy surgery (MIVS). Methods Of 111,876 vitrectomies (70,585 20-G 41,291 MIVS) performed, 45 cases developed acute-onset, postoperative endophthalmitis. Results The rate of culture positive and culture negative endophthalmitis was 0.021% (2.1/10,000 surgeries) and 0.019% (1.9/10,000 surgeries) overall, 0.031% (3.1/10,000 surgeries) and 0.025% (2.5/10,000 surgeries) in 20G, and 0.005% (0.5/10,000 surgeries) and 0.007% (0.7/10,000 surgeries) in the MIVS group respectively. Potential predisposing factors were as follows: diabetes, 46.7%; vitrectomy for vascular retinopathies, 44.4%; and vitrectomy combined with anterior segment surgeries, 35.5%. The culture proven rates were 53.3% overall, 55.0% for 20G and 40.0% for MIVS. The most common organism was Pseudomonas aeruginosa for 20G. Klebsiella and Staphylococcus aureus were isolated in the two culture positive cases in MIVS group. The follow-up period for the patients with endophthalmitis was 586.14 ± 825.15 days. Seven were lost to follow up beyond one week. Of the remaining 38, 13 (34.2%) cases had a favorable visual outcome (i.e., best-corrected visual acuity [BCVA] > 5/200) and 24 (63.2%) had unfavorable visual outcome (BCVA < 5/200). Group with culture test results negative had significantly better outcomes (P < 0.05) as compared to those with positive. Conclusions MIVS does not increase the risk of endophthalmitis. Outcomes are poor despite appropriate treatment, particularly in cases with culture results positive. PMID:29338030

There are limited comparative survival data for prostate cancer (PCa) patients managed with a low-dose rate brachytherapy (LDR-B) boost and dose-escalated external-beam radiotherapy (DE-EBRT) alone. To compare overall survival (OS) for men with unfavorable PCa between LDR-B and DE-EBRT groups. Using the National Cancer Data Base, we identified men with unfavorable PCa treated between 2004 and 2012 with androgen suppression (AS) and either EBRT followed by LDR-B or DE-EBRT (75.6-86.4Gy). Treatment selection was evaluated using logistic regression and annual percentage proportions. OS was analyzed using the Kaplan-Meier method, log-rank test, Cox proportional hazards, and propensity score matching. We identified 25038 men between 2004 and 2012, during which LDR-B boost utilization decreased from 29% to 14%. LDR-B was associated with better OS on univariate (7-yr OS: 82% vs 73%; p<0.001) and multivariate analyses (hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.64-0.77). Propensity score matching verified an OS benefit associated with LDR-B boost (HR 0.74, 95% CI 0.66-0.89). The OS benefit of LDR-B boost persisted when limited to men aged <60 yr with no comorbidities. On subset analysis, there was no interaction between treatment and age, risk group, or radiation dose. Limitations include the retrospective design, nonrandomized selection bias, and the absence of treatment toxicity, hormone duration, and cancer-specific outcomes. Between 2004 and 2012, LDR-B boost utilization declined and was associated with better OS compared to DE-EBRT alone. LDR-B boost is probably the ideal treatment option for men with unfavorable PCa, pending long-term results of randomized trials. We compared radiotherapy utilization and survival for prostate cancer (PCa) patients using a national database. We found that low-dose rate brachytherapy (LDR-B) boost, a method being used less frequently, was associated with better overall survival when compared to dose-escalated external-beam radiotherapy alone for men with unfavorable PCa. Randomized trials are needed to confirm that LDR-B boost is the ideal treatment. Copyright © 2017 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Aerobic glycolysis is one of the emerging hallmarks of cancer cells. In this study, we investigated the relationship between blocking mitochondrial pyruvate carrier (MPC) with MPC blocker UK5099 and the metabolic alteration as well as aggressive features of esophageal squamous carcinoma. It was found that blocking pyruvate transportation into mitochondria attenuated mitochondrial oxidative phosphorylation (OXPHOS) and triggered aerobic glycolysis, a feature of Warburg effect. In addition, the HIF-1α expression and ROS production were also activated upon UK5099 application. It was further revealed that the UK5099-treated cells became significantly more resistant to chemotherapy and radiotherapy, and the UK5099-treated tumor cells also exhibited stronger invasive capacity compared to the parental cells. In contrast to esophageal squamous epithelium cells, decreased MPC protein expression was observed in a series of 157 human squamous cell carcinomas, and low/negative MPC1 expression predicted an unfavorable clinical outcome. All these results together revealed the potential connection of altered MPC expression/activity with the Warburg metabolic reprogramming and tumor aggressiveness in cell lines and clinical samples. Collectively, our findings highlighted a therapeutic strategy targeting Warburg reprogramming of human esophageal squamous cell carcinomas. PMID:27911865

Current Status and Future Prospects for Esophageal Cancer Treatment

The local control effect of esophagectomy with three-field lymph node dissection (3FLD) is reaching its limit pending technical advancement. Minimally invasive esophagectomy (MIE) by thoracotomy is slowly gaining acceptance due to advantages in short-term outcomes. Although the evidence is slowly increasing, MIE is still controversial. Also, the results of treatment by surgery alone are limiting, and multimodality therapy, which includes surgical and non-surgical treatment options including chemotherapy, radiotherapy, and endoscopic treatment, has become the mainstream therapy. Esophagectomy after neoadjuvant chemotherapy (NAC) is the standard treatment for clinical stages II/III (except for T4) esophageal cancer, whereas chemoradiotherapy (CRT) is regarded as the standard treatment for patients who wish to preserve their esophagus, those who refuse surgery, and those with inoperable disease. CRT is also usually selected for clinical stage IV esophageal cancer. On the other hand, with the spread of CRT, salvage esophagectomy has traditionally been recognized as a feasible option; however, many clinicians oppose the use of surgery due to the associated unfavorable morbidity and mortality profile. In the future, the improvement of each treatment result and the establishment of individual strategies are important although esophageal cancer has many treatment options. PMID:28003586

Because the association and its clinical relevance between comorbidities and primary hand osteoarthritis (OA) disease burden is unclear, we studied this in patients with hand OA from our Hand OSTeoArthritis in Secondary care (HOSTAS) cohort. Cross-sectional data from the HOSTAS study were used, including consecutive patients with primary hand OA. Nineteen comorbidities were assessed: 18 self-reported (modified Charlson index and osteoporosis) and obesity (body mass index ≥ 30 kg/m 2 ). Mean differences were estimated between patients with versus without comorbidities, adjusted for age and sex: for general disease burden [health-related quality of life (HRQOL), Medical Outcomes Study Short Form-36 physical component scale (0-100)] and disease-specific burden [self-reported hand function (0-36), pain (0-20; Australian/Canadian Hand OA Index), and tender joint count (TJC, 0-30)]. Differences above a minimal clinically important improvement/difference were considered clinically relevant. The study included 538 patients (mean age 61 yrs, 86% women, 88% fulfilled American College of Rheumatology classification criteria). Mean (SD) HRQOL, function, pain, and TJC were 44.7 (8), 15.6 (9), 9.3 (4), and 4.8 (5), respectively. Any comorbidity was present in 54% (287/531) of patients and this was unfavorable [adjusted mean difference presence/absence any comorbidity (95% CI): HRQOL -4.4 (-5.8 to -3.0), function 1.9 (0.4-3.3), pain 1.4 (0.6-2.1), TJC 1.3 (0.4-2.2)]. Number of comorbidities and both musculoskeletal (e.g., connective tissue disease) and nonmusculoskeletal comorbidities (e.g., pulmonary and cardiovascular disease) were associated with disease burden. Associations with HRQOL and function were clinically relevant. Comorbidities showed clinically relevant associations with disease burden. Therefore, the role of comorbidities in hand OA should be considered when interpreting disease outcomes and in patient management.

Neuroblastoma is an embryonal tumor with contrasting clinical courses. Despite elaborate stratification strategies, precise clinical risk assessment still remains a challenge. The purpose of this study was to develop a PCR-based predictor model to improve clinical risk assessment of patients with neuroblastoma. The model was developed using real-time PCR gene expression data from 96 samples and tested on separate expression data sets obtained from real-time PCR and microarray studies comprising 362 patients. On the basis of our prior study of differentially expressed genes in favorable and unfavorable neuroblastoma subgroups, we identified three genes, CHD5, PAFAH1B1, and NME1, strongly associated with patient outcome. The expression pattern of these genes was used to develop a PCR-based single-score predictor model. The model discriminated patients into two groups with significantly different clinical outcome [set 1: 5-year overall survival (OS): 0.93 ± 0.03 vs. 0.53 ± 0.06, 5-year event-free survival (EFS): 0.85 ± 0.04 vs. 0.042 ± 0.06, both P < 0.001; set 2 OS: 0.97 ± 0.02 vs. 0.61 ± 0.1, P = 0.005, EFS: 0.91 ± 0.8 vs. 0.56 ± 0.1, P = 0.005; and set 3 OS: 0.99 ± 0.01 vs. 0.56 ± 0.06, EFS: 0.96 ± 0.02 vs. 0.43 ± 0.05, both P < 0.001]. Multivariate analysis showed that the model was an independent marker for survival (P < 0.001, for all). In comparison with accepted risk stratification systems, the model robustly classified patients in the total cohort and in different clinically relevant risk subgroups. We propose for the first time in neuroblastoma, a technically simple PCR-based predictor model that could help refine current risk stratification systems. ©2012 AACR.

Tumor necrosis factor (TNF) receptor family members play a key role in the regulation of biological functions such as differentiation, proliferation and apoptosis of various cell types. We studied co-expression profiles of death receptors from the TNF family [TNF-related apoptosis-inducing ligand receptor (TRAILR) 1 to 3, TNF receptor 1 (TNFR1) and FAS receptor (FAS)] on peripheral blood blasts from 46 patients with acute myeloid leukemia (AML) at first diagnosis by flow cytometry and correlated the obtained specific fluorescence indices (SFI) with morphological, cytogenetic and clinical parameters. We found that the expression of TRAILR2 and R3 was significantly increased in unfavorable risk groups, according to the National Comprehensive Cancer Network. Additionally, cut-off analyses for TRAILR2 and TNFR1 showed significantly shorter overall survival, earlier disease onset, higher proportions of cases with unfavorable prognosis and higher probability of relapse when SFIs were above the established cut-off. We demonstrate that high co-expression of death receptors on blasts is an independent predictor of poor prognosis in AML. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

To determine long-term efficacy and safety of epilepsy surgery in children and adolescents with malformations of cortical development (MCD) and to identify differences in seizure outcome of the various MCD subgroups. Special focus was set on the newly introduced International League Against Epilepsy (ILAE) classification of focal cortical dysplasia (FCD). This is a single center retrospective cross-sectional analysis of prospectively collected data. age at surgery <18 years, pre-surgical evaluation and epilepsy surgery performed at the Vienna pediatric epilepsy center, histologically proven MCD, complete follow-up data for at least 12 months. Clinical variables evaluated: type and localization of MCD, type of surgery and a variety of clinical characteristics reported to be associated with (un-)favorable outcomes. MCD were classified following the existing classification schemes (Barkovich et al., 2012. Brain. 135, 1348-1369; Palmini et al., 2004. Neurology. 62, S2-S8) and the ILAE classification for FCD recently proposed by Blümcke in 2011. Seizure outcome was classified using the ILAE classification proposed by Wieser in 2001. 60 Patients (51.7% male) were included. Follow up was up to 14 (mean 4.4 ± 3.2) years. Mean age at surgery was 8.0 ± 6.0 (median 6.0) years; mean age at epilepsy onset was 2.9 ± 3.2 (median 2.0) years; duration of epilepsy before surgery was 4.8 ± 4.4 (median 3.0) years. 80% of the patients were seizure free at last follow-up. AEDs were successfully withdrawn in 56.7% of all patients. Extended surgery, lesion localization in the temporal lobes and absence of inter-ictal spikes in postsurgical EEG recordings were predictive of favorable seizure outcomes after surgery. However, no association was found between outcome and MCD sub-types. Epilepsy surgery is highly effective in carefully selected drug-resistant children with MCD. Surrogate markers for complete resection of the epileptogenic zone remain the only significant predictors for seizure freedom after surgery. Copyright © 2014 Elsevier B.V. All rights reserved.

Patients with renal disease typically have severely calcified peripheral arterial disease. As a result, this population may have worse clinical outcomes following endovascular intervention compared to patients without renal insufficiency. Clinical trials typically exclude this patient population. Analysis of the CONFIRM I-III registries revealed 1105 patients with renal disease (1777 lesions) and 1969 patients without renal disease (2907 lesions) who underwent orbital atherectomy. This subanalysis compared the composite procedural complication rate including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation in patients with and without renal disease. Patients with renal disease had a higher prevalence of diabetes (P<.001), hypertension (P<.001), hyperlipidemia (P<.001), and coronary artery disease (P<.001), Rutherford 5 or 6 lesions (P<.001), as well as more lesions treated (P<.001), more vessels treated (P<.001), and more below-the-knee lesions (P<.001). The renal disease and non-renal disease groups had similar composite procedural complication rates (21.3% vs. 22.4%; P=.46), dissection (11.1% vs. 11.5%; P=.83), perforation (0.6% vs. 0.8%; P=.55), slow flow (5.0% vs. 4.2%; P=.19), spasm (6.7% vs. 6.2%; P=.40), embolism (1.7% vs. 2.6%; P=.12), and thrombus formation (1.4% vs. 1.0%; P=.56). The renal disease group had a trend toward decreased vessel closure (1.1% vs. 1.6%; P=.08). Plaque modification with orbital atherectomy resulted in similar low rates of procedural complications in the renal disease group compared with the non-renal disease group despite more unfavorable baseline clinical and lesion characteristics in the renal disease group.

To determine the usefulness of physical phenotype of frailty, cognitive impairment, and serum albumin for risk stratification of elderly medical impatients. Prospective, observational cohort study. A general internal medicine unit of a university hospital in Italy. Inpatients with an average age of 80.8 ± 7.5 yr (N = 470). Frailty was defined using the Study of Osteoporotic Fractures Index, a parsimonious version of the physical phenotype (two of the following markers: weight loss, inability to rise five times from a chair, and exhaustion). Two frailty markers from non-physical dimensions were also evaluated: cognitive impairment (Mini-Cog score < 3) and low serum albumin on ward admission (< 3,5 gr/dl). Logistic regression adjusted for preadmission and admission-related confounders was used to investigate whether the physical phenotype of frailty and the two non-physical markers were associated with ward length of stay and unfavorable discharge (death plus any other ward discharge disposition different from direct return home). Areas Under the receiver operating characteristic Curve (AUCs) and Likelihood Ratios (LRs) were used for evaluation of discriminatory ability and clinical usefulness of significant predictors. The physical phenotype of frailty was associated with both study outcomes (p < 0.010) but the association was mainly mediated by chair standing ability. Non-physical markers were associated only with unfavourable discharge (p < 0.001). All of these predictors, either alone or in combination, had poor discriminatory ability (AUCs < 0.70) and poor clinical usefulness (+LRs near 1) for the study outcomes. The physical phenotype of frailty appears of limited clinical use for risk stratification of older medical inpatients. Combination with markers from non-physical dimensions does not improve its prognostic abilities.

Gastrointestinal symptoms are among the most frequent complaints of patients infected with human immunodeficiency virus (HIV). An endoscopic and histopathological survey of digestive tract diseases among HIV-infected patients monitored in the Clinic of Infectious Diseases I from Tirgu Mures, Romania. Retrospective, observational study, on a group of 38 HIV-positive patients admitted to the Clinic of Infectious Diseases I from Tirgu Mures, Romania, during 2006-2013, undergoing upper/lower endoscopy. We collected data regarding the results of endoscopy and histopathological examination, CD4+ T-lymphocytes levels, microbiological examinations and outcome. Statistical analysis, performed by using Microsoft Office Excel 2007 and GraphPad Prism 5 programs, included contingency tables analysis and comparing means. Our study depicted a variety of digestive disorders among HIV-infected patients, ranging from opportunistic infections to HIV enteropathy and non-HIV-associated conditions. The presence of Candida esophagitis implied significantly lower levels of CD4+ T-cells (p=0.0043). We found a statistically significant negative association between antiretroviral therapy and the presence of opportunistic infections (p=0.0375, OR=0.2030, 95% CI 0.0423-0.9741). Thirteen (34.21%) patients died, mostly due to tuberculosis and central nervous system infections. All were diagnosed with acquired immunodeficiency syndrome (AIDS). HIV-infected patients experience a wide variety of digestive tract disorders, both AIDS-defining illnesses and non-HIV-associated conditions. Gastrointestinal opportunistic infections occur more often among patients with low CD4+ T-cells levels and in those not receiving antiretroviral therapy. Although digestive conditions did not represent direct causes of death in our study, they may predict an unfavorable outcome in AIDS-stage patients.

Poor nutritional status and protein-energy wasting are common among maintenance dialysis patients and associated with unfavorable outcomes. Providing foods, meal trays, snack boxes, and/or oral nutritional supplements during hemodialysis can improve nutritional status and might also reduce inflammation, enhance health-related quality of life, boost patient satisfaction, and improve survival. Potential challenges include postprandial hypotension and other hemodynamic instabilities, aspiration risk, gastrointestinal symptoms, hygiene issues, staff burden, reduced solute removal, and increased costs. Differing in-center nutrition policies exist within organizations and countries around the world. Recent studies have demonstrated clinical benefits and highlight the need to work toward clear guidelines. Meals or supplements during hemodialysis may be an effective strategy to improve nutritional status with limited reports of complications in real-world scenarios. Whereas larger multicenter randomized trials are needed, meals and supplements during hemodialysis should be considered as a part of the standard-of-care practice for patients without contraindications.

Deletion of chromosome 17p with a loss of p53 is an unfavorable cytogenetic change in chronic lymphocytic leukemia (CLL) with poor clinical outcome. Since p53 affects mitochondrial function and integrity, we examined possible mitochondrial changes in CLL mice with TCL1-Tg/p53−/− and TCL1-Tg/p53+/+ genotypes and in primary leukemia cells from CLL patients with or without 17p-deletion. Although the expression of mitochondrial COX1, ND2, and ND6 decreased in p53−/−CLL cells, there was an increase in mitochondrial biogenesis as evidenced by higher mitochondrial mass and mtDNA copy number associated with an elevated expression of TFAM and PGC-1α. Surprisingly, the overall mitochondrial respiratory activity and maximum reserved capacity increased in p53−/− CLL cells. Our study suggests that leukemia cells lacking p53 seem able to maintain respiratory function by compensatory increase in mitochondrial biogenesis. PMID:27650502

In tumor tissues, cancer cells, tumor infiltrating macrophages and tumor neo-vessels in close spatial vicinity with one another form tumor invasion unit, which is a biologically important tumor microenvironment of metastasis to facilitate cancer invasion and metastasis. Establishing an in situ molecular imaging technology to simultaneously reveal these three components is essential for the in-depth investigation of tumor invasion unit. In this report, we have developed a computer-aided algorithm by quantum dots (QDs)-based multiplexed molecular imaging technique for such purpose. A series of studies on gastric cancer tumor tissues demonstrated that the tumor invasion unit was correlated with major unfavorable pathological features and worse clinical outcomes, which illustrated the significantly negative impacts and predictive power of tumor invasion unit on patient overall survival. This study confirmed the technical advantages of QDs-based in situ and simultaneous molecular imaging of key cancer molecules to gain deeper insights into the biology of cancer invasion.

Research evaluating the relation of workplace psychosocial factors to mental health among U.S. women of different racial/ethnic backgrounds is limited. This study investigated the relationship between work-related psychosocial factors and mental health among non-Hispanic Black, Hispanic, and non-Hispanic White women using data from the 2010 National Health Interview Survey. Independent variables of interest included job insecurity, workplace harassment, and work-family conflict (WFC). Multiple Poisson regression models were used to examine the associations between the outcome and independent variables. The prevalence of unfavorable mental health was highest among non-Hispanic Black women (36%) compared to Hispanic (34%) and non-Hispanic White (30%) women. A higher proportion of non-Hispanic Black women reported WFC compared to Hispanics and non-Hispanic Whites (χ 2 = 15.50, p < .01), while more Hispanics reported job insecurity (χ 2 = 116.81, p < .01). Prevalence of workplace harassment did not differ significantly by race/ethnicity. Odds of unfavorable mental health were significantly higher for women reporting psychosocial work factors. Unexpectedly, a greater association between psychosocial work factors and unfavorable mental health was observed among non-Hispanic White women compared to non-White women; however, caution should be taken in interpreting these cross-sectional results. Future studies should investigate temporal associations and additional psychosocial variables that were not available for use in the current study.

Aneurysmal subarachnoid hemorrhage (SAH) is characterized by important changes in the autonomic nervous system with potentially adverse consequences. The baroreflex has a key role in regulating the autonomic nervous system. Its role in SAH outcome is not known. The purpose of this study was to evaluate the association between the baroreflex and the functional 3-month outcome in SAH. The study used a prospective database of 101 patients hospitalized for SAH. We excluded patients receiving β-blockers or noradrenaline. Baroreflex sensitivity (BRS) was measured using the cross-correlation method. A good outcome was defined by a Glasgow Outcome Scale score at 4 or 5 at 3 months. Forty-eight patients were included. Median age was 58 years old (36-76 years); women/men: 34/14. The World Federation of Neurosurgery clinical severity score on admission was 1 or 2 for 73% of patients. In the univariate analysis, BRS ( P =0.007), sedation ( P =0.001), World Federation of Neurosurgery score ( P =0.001), Glasgow score ( P =0.002), Fisher score ( P =0.022), and heart rate ( P =0.037) were associated with outcome. The area under the receiver operating characteristic curve for the model with BRS as a single predictor was estimated at 0.835. For each unit increase in BRS, the odds for a good outcome were predicted to increase by 31%. Area under the receiver operating characteristic curve for heart rate alone was 0.670. In the multivariate analysis, BRS (odds ratio, 1.312; 95% confidence interval, 1.048-1.818; P =0.018) and World Federation of Neurosurgery (odds ratio, 0.382; 95% confidence interval, 0.171-0.706; P =0.001) were significantly associated with outcome. Area under the receiver operating characteristic curve was estimated at 0.900. In SAH, early BRS was associated with 3-month outcome. This conclusion requires confirmation on a larger number of patients in a multicentre study. © 2018 American Heart Association, Inc.

To describe the clinical encounters that occur when a palliative care team provides patient care and the features that influence these encounters and indicate whether they are favorable or unfavorable depending on the expectations and feelings of the various participants. A qualitative case study conducted via participant observation. A total of 12 observations of the meetings of palliative care teams with patients and families in different settings (home, hospital and consultation room) were performed. The visits were follow-up or first visits, either scheduled or on demand. Content analysis of the observation was performed. The analysis showed the normal follow-up activity of the palliative care unit that was focused on controlling symptoms, sharing information and providing advice on therapeutic regimens and care. The environment appeared to condition the patients' expressions and the type of patient relationship. Favorable clinical encounter conditions included kindness and gratitude. Unfavorable conditions were deterioration caused by approaching death, unrealistic family objectives and limited resources. Home visits from basic palliative care teams play an important role in patient and family well-being. The visits seem to focus on controlling symptoms and are conditioned by available resources.

Unfavorable results of major studies have led to a large shrinkage of the market for hormone replacement therapy (HRT) in the last 6 years. Some scientists continue to strongly support the use of HRT. We analyzed a sample of partisan editorializing articles on HRT to examine their arguments, the reporting of competing interests, the journal venues and their sponsoring societies. Through Thomson ISI database, we selected articles without primary data written by the five most prolific editorialists that addressed clinical topics pertaining to HRT and that were published in regular journal issues in 2002-2008. We recorded the number of articles with a partisan stance and their arguments, the number of partisan articles that reported conflicting interests, and the journal venues and their sponsoring societies publishing the partisan editorials. We analyzed 114 eligible articles (58 editorials, 16 guidelines, 37 reviews, 3 letters), of which 110 (96%) had a partisan stance favoring HRT. Typical arguments were benefits for menopausal and related symptoms (64.9%), criticism of unfavorable studies (78.9%), preclinical data that showed favorable effects of HRT (50%), and benefits for major outcomes such as osteoporosis and fractures (49.1%), cardiovascular disease (31.6%), dementia (24.6%) or colorectal cancer (20.2%), but also even breast cancer (4.4%). All 5 prolific editorialists had financial relationships with hormone manufacturers, but these were reported in only 6 of the 110 partisan articles. Four journals published 15-37 partisan articles each. The medical societies of these journals reported on their websites that several pharmaceutical companies sponsored them or their conferences. There is a considerable body of editorializing articles favoring HRT use and very few of these articles report conflicts of interest. Full disclosure of conflicts of interest is needed, especially for articles without primary data.

BLZF1, a member of b-ZIP family, has been implicated in epigenetic regulation and Wnt/β-catenin signaling. Its expression and clinical significance in human cancers remain largely unknown. In this study, we showed that BLZF1 expression was reduced in hepatocellular carcinoma (HCC) tissues, compared to the paracarcinoma tissues, at both mRNA and protein levels. Results of immunohistochemistry revealed that BLZF1 was presented in both nuclear and cytoplasm. Decreased expression of nuclear and cytosolic BLZF1 in HCC was depicted in 68.2% and 79.2% of the 634 cases. Nuclear BLZF1 expression was significantly associated with tumor multiplicity (P = 0.048) and tumor capsule (P = 0.028), while cytosolicmore » BLZF1 expression was correlated with serum AFP level (P = 0.017), tumor differentiation (P = 0.001) and tumor capsule (P = 0.003). Kaplan–Meier analysis indicated both nuclear and cytosolic BLZF1 expression was associated with poor overall survival. Low nuclear BLZF1 also indicated unfavorable disease-free survival and high tendency of tumor recurrence. Furthermore, multiple Cox regression analysis revealed nuclear BLZF1 as an independent factor for overall survival (Hazard Ratio (HR) = 0.827, 95% confident interval (95%CI): 0.697–0.980, P = 0.029). The prognostic value of BLZF1 was further confirmed by stratified analyses. Collectively, our data suggest BLZF1 is a novel unfavorable biomarker for prognosis of patients with HCC. - Highlights: • BLZF1 expression was much lower in HCC tissues. • Low BLZF1 expression was associated with poor outcomes in a cohort of 634 HCC patients. • Multiple Cox regression analysis indicated nuclear BLZF1 as an independent predictor for overall survival.« less

Shatté, Andrew; Perlman, Adam; Smith, Brad; Lynch, Wendy D

2017-02-01

To examine whether resilience has a protective effect in difficult work environments. A survey of 2063 individuals measured individual resilience, stress, burnout, sleep problems, likelihood of depression, job satisfaction, intent to quit, absences, and productivity. It also measured work characteristics: job demands, job influence, and social support. Multivariate and logistic regression models examined the main effects and interactions of resilience and job characteristics. High strain work environments (high demand, low influence, and low support) have an unfavorable effect on all outcomes. Resilience has a protective effect on all outcomes. For stress, burnout, and sleep, higher resilience has a more protective effect under low-strain conditions. For depression, absence and productivity, resilience has a more protective effect when job strain is high. Workers with high resilience have better outcomes in difficult work environments.

To ascertain the perception of third and fourth year medical students and interns (fifth year) about the educational environment during the clinical education phase and during the internship at Instituto Mexicano del Seguro Social (IMSS). A questionnaire with 120 items was developed to evaluate whether IMSS educational environment encourages reflection and criticism among medical students and interns. The highest possible score of the questionnaire was 240 points. A t test was used to compare the score of the students who were classified according to the term in which they were enrolled. 1997 medical students and 1075 interns from 46 IMSS clinical settings answered the previously validated questionnaire. Seventy percent of the students considered that the educational environment was not very favorable for reflection and criticism; 19% perceived it as favorable and 11% as unfavorable. The median score of third and fourth year medical students, was 134.9 (range 80-193; p = 0.27), interns' score was 130.4 (range 80-208; p = 0.001). The perception of the medical students in clinical settings other than Mexico City was less unfavourable (median 132.8; range 63.5-208); p = 0.003). apparently, the occupational environment influences the educational environments where the courses take place. As long as the students advance in their courses and get involved in clinical practice, their perception of the educational environment becomes unfavorable.

Complex head and neck reconstruction often mandates free tissue transfer to achieve the most optimal outcomes. Unfortunately, such challenging cases are not without risks of complications, the most dreaded of which is loss of the free flap. Aside from loss of the free flap, there are several other potential complications that can result following head and neck reconstruction. Certain complications are avoided with careful planning, others require significant revisions and in certain cases another free flap. This article presents the experience managing a series of unique complications following free flap head and neck reconstruction. Published by Elsevier Inc.

Hypertensive disorders of pregnancy are among the leading preventable contributors of maternal and fetal adverse outcomes, including maternal and fetal death. Blood pressure increase has a strong association with unfavorable pregnancy outcomes, including stroke and pulmonary edema. A persistent blood pressure measurement greater than or equal to 160/110 mm Hg lasting for more than 15 minutes, during pregnancy or postpartum, is considered an obstetric emergency and requires rapid appropriate treatment. Following evidence-based guidelines, implementing institutional polices, and understanding the classification and pathophysiology of hypertensive disorders of pregnancy are essential and can significantly improve the rate of preventable complications.

Iatrogenic cerebral arterial gas embolism (CAGE) is an uncommon but potentially a fatal condition. Hyperbaric oxygen (HBO2) therapy is the only definitive treatment for patients with CAGE presenting with acute neurologic deficits. We reviewed medical records and neuroimaging of consecutive CAGE patients treated with HBO2 at a state referral hyperbaric facility over a 22-year period. We analyzed the effect of demographics, source of intra-arterial gas, signs and symptoms, results of imaging studies, time between event and HBO2 treatment, and response to HBO2 treatment in 36 consecutive patients. Favorable outcome was defined by complete resolution or improvement of CAGE signs and symptoms at 24 h after HBO2 treatment. Unfavorable outcome was defined by unchanged or worsened neurologic signs and symptoms or in hospital death. A total of 26 (72%) of the 36 patients had favorable outcome. Patients with favorable outcome were younger compared to those with unfavorable outcome (mean age [years, SD] 44.7 ± 17.8 vs. 58.1 ± 24.1, p = 0.08). Cardiopulmonary symptoms were significantly more common in CAGE related to venous source of gas compared to arterial source (p = 0.024) but did not influence the rate of favorable outcomes. Adjusted multivariate analysis demonstrated that time from event to HBO2 ≤ 6 h (positively) and the presence of infarct/edema on head computerized tomography (CT)/magnetic resonance imaging (MRI) before HBO2 (negatively) were independent predictors of favorable outcome at 24 h after HBO2 treatment [odds ratio (OR) 9.08 confidence interval (CI) (1.13-72.69), p = 0.0376, and (OR) 0.034 (CI) (0.002-0.58), p = 0.0200, respectively]. Two of the 36 patients were treated with thrombolytics because of acute focal deficits and suspected ischemia-one with intravenous and the second with intra-arterial thrombolysis. The latter patient developed fatal intracerebral hemorrhage. A high proportion of CAGE patients treated with HBO2 had favorable outcomes. Time-to-HBO2 ≤ 6 h increased the odds of favorable outcome, whereas the presence of infarct/edema on CT/MRI scan before HBO2 reduced the odds of a favorable outcome. Timely diagnosis and differentiation from thrombo-embolic ischemic events appears to be an important determinant of successful HBO2 treatment.

In low-resource settings, access to emergency cesarean section is associated with various delays leading to poor neonatal outcomes. In this study, we described the delays a mother faces when needing emergency cesarean delivery and assessed the effect of these delays on neonatal outcomes in Rwanda. This retrospective study included 441 neonates and their mothers who underwent emergency cesarean section in 2015 at three district hospitals in Rwanda. Four delays were measured: duration of labor prior to hospital admission, travel time from health center to district hospital, time from admission to surgical incision, and time from decision for emergency cesarean section to surgical incision. Neonatal outcomes were categorized as unfavorable (APGAR <7 at 5 min or death) and favorable (alive and APGAR ≥7 at 5 min). We assessed the relationship between each type of delay and neonatal outcomes using multivariate logistic regression. In our study, 9.1% (40 out of 401) of neonates had an unfavorable outcome, 38.7% (108 out of 279) of neonates' mothers labored for 12-24 h before hospital admission, and 44.7% (159 of 356) of mothers were transferred from health centers that required 30-60 min of travel time to reach the district hospital. Furthermore, 48.1% (178 of 370) of cesarean sections started within 5 h after hospital admission and 85.2% (288 of 338) started more than 30 min after the decision for cesarean section was made. Neonatal outcomes were significantly worse among mothers with more than 90 min of travel time from the health center to the district hospital compared to mothers referred from health centers located on the same compound as the hospital (aOR = 5.12, p = 0.02). Neonates with cesarean deliveries starting more than 30 min after decision for cesarean section had better outcomes than those starting immediately (aOR = 0.32, p = 0.04). Longer travel time between health center and district hospital was associated with poor neonatal outcomes, highlighting a need to decrease barriers to accessing emergency maternal services. However, longer decision to incision interval posed less risk for adverse neonatal outcome. While this could indicate thorough pre-operative interventions including triage and resuscitation, this relationship should be studied prospectively in the future.

High grade serous ovarian cancer (HGSOC) is characterized by extensive local, i.e. peritoneal, tumor spread, manifested in two different clinical presentations, miliary (many millet sized peritoneal implants) and non-miliary (few large exophytically growing peritoneal nodes), and an overall unfavorable outcome. HGSOC is thought to arise from fallopian tube secretory epithelial cells, via so called serous tubal intraepithelial carcinomas (STICs) but an ovarian origin was never ruled out for at least some cases. Comparative transcriptome analyses of isolated tumor cells from fresh HGSOC tissues and (immortalized) ovarian surface epithelial and fallopian tube secretory epithelial cell lines revealed a close relation between putative origin and tumor spread characteristic, i.e. miliary from tubes and non-miliary from ovaries. The latter were characterized by more mesenchymal cell characteristics, more adaptive tumor immune infiltration, and a favorable overall survival. Several molecular sub-classification systems (Crijns' overall survival signature, Yoshihara's subclasses, and a collagen-remodeling signature) seem to already indicate origin. Putative origin alone is a significant independent predictor for HGSOC outcome, validated in independent patient cohorts. Characteristics of both spread types could guide development of new targeted therapeutics, which are urgently needed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To evaluate the occurrence, treatment, and outcome of subdural empyema complicating community-acquired bacterial meningitis in adults. Case series from a prospective nationwide cohort study from Dutch hospitals from 2006 to 2011. Subdural empyema was diagnosed in 28 of 1,034 episodes (2.7%), and was present on admission in 10 episodes and diagnosed during admission in 18. Predisposing conditions were present in 26 patients (93%), and consisted of otitis or sinusitis in 21 patients (75%). In all these patients the otitis or sinusitis spread to the subdural space. Twenty-three patients (82%) presented with neurologic symptoms (paresis, focal seizures, dysesthesia contralateral to the empyema). Streptococcus pneumoniae was identified in 26 patients (93%) and Streptococcus pyogenes in 1 (3%); 1 patient had negative CSF cultures. Clinical course was frequently complicated with seizures (50%), focal neurologic abnormalities (54%), and hearing impairment (39%), causing an unfavorable outcome in 19 episodes (68%). Neurosurgical evacuation of the empyema was performed in 5 patients, all with considerable midline shift. Although rare, subdural empyema must be considered in patients with community-acquired bacterial meningitis and otitis or sinusitis, focal neurologic deficits, or epileptic seizures. S pneumoniae is the predominant causative organism and neurosurgical intervention should be regarded as first-choice therapy in patients with empyema causing midline shift and focal neurologic abnormalities or a decreased level of consciousness.

Angiogenesis is a fundamental process for brain development and repair. Thrombospondin-1 is the first identified endogenous angiogenesis inhibitor. Its expression in rat brain is upregulated after intracerebral hemorrhage (ICH). We determined whether plasma thrombospondin-1 concentrations are associated with injury severity and prognosis in ICH patients. This observational, prospective study recruited 110 patients and 110 age- and gender-matched healthy controls. Blood samples were collected from the patients at admission and from the healthy controls at study entry to measure plasma thrombospondin-1 concentrations. The endpoints included 1-week mortality, 6-month mortality, 6-month overall survival and 6-month unfavorable outcome (modified Rankin Scale score >2). Plasma thrombospondin-1 concentrations were markedly higher in patients than in healthy controls. Thrombospondin-1 was an independent predictive factor for all endpoints and plasma thrombospondin-1 concentrations were highly associated with injury severity reflected by hematoma volume and National Institutes of Health Stroke Scale score. Under receiver operating characteristic curves, plasma thrombospondin-1 concentrations had similar predictive values compared with hematoma volume and National Institutes of Health Stroke Scale score. Increased plasma thrombospondin-1 concentrations following ICH are independently associated with injury severity and short-term and long-term clinical outcomes. Copyright © 2015 Elsevier B.V.

Purpose We aimed to examine the risk factors, time of onset, incidence rates, and outcomes of thromboembolic events induced by bevacizumab in patients with cancer using the Japanese Adverse Drug Event Report (JADER) database of the Pharmaceuticals and Medical Devices Agency. Methods Adverse event data recorded in the JADER database between January 2004 and January 2015 were used. After screening the data using the generic drug name bevacizumab, patient data were classified into two groups by age and five groups by cancer type. The histories of disorders were also categorized. Arterial thromboembolic event and venous thromboembolic event were classified as "favorable" or "unfavorable" outcomes. Results In total, 6076 patients were reported to have developed adverse events during the sample period, of which 233 and 453 developed arterial thromboembolic event and venous thromboembolic event, respectively. Logistic analysis suggested that the presence of cancer was a significant risk factor for both arterial thromboembolic event and venous thromboembolic event. Age (≥70 years), histories of either hypertension or diabetes mellitus were also risk factors for arterial thromboembolic event. Median cumulative times of onset for arterial thromboembolic event and venous thromboembolic event were 60 and 80 days, respectively, and were not significantly different by the log-rank test. By the chi-square test, the rate of unfavorable outcomes was found to be higher after developing arterial thromboembolic event than after venous thromboembolic event. Conclusion Thromboembolism is a leading cause of mortality in patients with cancer. Patients should be monitored for the symptoms of thromboembolic events right from the initial stages of bevacizumab treatment.

The aim of this study was to verify the association of echocardiogram, ferritin, C-reactive protein, and leukocyte count with unfavorable outcomes in pediatric sepsis. A prospective cohort study was carried out from March to December 2014, with pediatric critical care patients aged between 28 days and 18 years. Inclusion criteria were diagnosis of sepsis, need for mechanical ventilation for more than 48h, and vasoactive drugs. Serum levels of C-reactive protein, ferritin, and leukocyte count were collected on the first day (D0), 24h (D1), and 72h (D3) after recruitment. Patients underwent transthoracic echocardiography to determine the ejection fraction of the left ventricle on D1 and D3. The outcomes measured were length of hospital stay and in the pediatric intensive care unit, mechanical ventilation duration, free hours of VM, duration of use of inotropic agents, maximum inotropic score, and mortality. Twenty patients completed the study. Patients with elevated ferritin levels on D0 had also fewer ventilator-free hours (p=0.046) and higher maximum inotropic score (p=0.009). Patients with cardiac dysfunction by echocardiogram on D1 had longer hospital stay (p=0.047), pediatric intensive care unit stay (p=0.020), duration of mechanical ventilation (p=0.011), maximum inotropic score (p=0.001), and fewer ventilator-free hours (p=0.020). Cardiac dysfunction by echocardiography and serum ferritin value was significantly associated with unfavorable outcomes in pediatric patients with sepsis.

2013-01-01

Considerable interest has been generated from the results of recent clinical trials using SMOOTHENED (SMO) antagonists to inhibit the growth of HEDGEHOG (HH) signaling dependent tumors. This interest is tempered by the discovery of SMO mutations mediating resistance, underscoring the rationale for developing therapeutic strategies that interrupt HH signaling at levels distinct from those inhibiting SMO function. Here, we demonstrate that HH dependent non-small cell lung carcinoma (NSCLC) growth is sensitive to blockade of the HH pathway upstream of SMO, at the level of HH ligand processing. Individually, the use of different lentivirally delivered shRNA constructs targeting two functionally distinct HH-processing proteins, SKINNY HEDGEHOG (SKN) or DISPATCHED-1 (DISP-1), in NSCLC cell lines produced similar decreases in cell proliferation and increased cell death. Further, providing either an exogenous source of processed HH or a SMO agonist reverses these effects. The attenuation of HH processing, by knocking down either of these gene products, also abrogated tumor growth in mouse xenografts. Finally, we extended these findings to primary clinical specimens, showing that SKN is frequently over-expressed in NSCLC and that higher DISP-1 expression is associated with an unfavorable clinical outcome. Our results show a critical role for HH processing in HH-dependent tumors, identifies two potential druggable targets in the HH pathway, and suggest that similar therapeutic strategies could be explored to treat patients harboring HH ligand dependent cancers.

Formulary restrictions are implemented to reduce pharmacy costs and ensure appropriate use of pharmaceutical products. As adoption of formulary restrictions increases with rising pharmacy costs, there is a need to better understand the potential effect of formulary restrictions on patient and payer outcomes. To conduct a systematic literature review that assesses the effect of formulary restrictions on the following outcomes: medication adherence, clinical outcomes, treatment satisfaction, drug utilization, health care resource utilization, and economic outcomes. Studies published in 2005 or later were identified from the MEDLINE, Embase, and Cochrane databases and the National Health Service Economic Evaluation Database, using 2 sets of search terms. A total of 17 formulary restriction terms (e.g., step therapy [ST] and prior authorization [PA]) and 55 outcome terms were included, resulting in 935 unique search term combinations. Two reviewers independently conducted analyses of the titles, abstracts, and full-text articles. The search was limited to English-language articles that evaluated the effect of ST and/or PA placed by U.S. third-party payers on the following outcomes: patient outcomes (medication adherence, clinical outcomes, and treatment satisfaction) and payer outcomes (drug utilization, health care resource utilization, and economic outcomes). Of 2,321 reviewed articles, 59 articles met the study inclusion criteria. The included studies assessed the effect of ST (n = 18), PA (n = 35), or both (n = 6) on medication adherence (n = 14), clinical outcomes (n = 12), treatment satisfaction (n = 2), drug utilization (n = 39), health care resource utilization (n = 18), and economic outcomes (n = 42). The 59 articles measured 164 outcomes across the patient, health care resource utilization, and economic outcome categories of interest. Of the total number of outcomes, 50.6% (n = 83) were negative in direction or were unfavorable, whereas 40.2% (n = 66) were positive in direction or were favorable, when the perspectives of patients and payers were considered. Of the total number of drug utilization outcomes reported (n = 46), the majority showed lower drug utilization (> 90%). However, in some of the articles, pharmacy cost savings resulting from lower drug utilization appeared to be offset by increased medical costs. Formulary coverage decisions may have unintended consequences on patient and payer outcomes despite lower drug utilization and pharmacy cost savings; therefore, careful evaluation of restrictions before policy implementation and continued reevaluation after implementation is warranted. This study was funded by Novartis Pharmaceuticals. Park and Ko are employed by Novartis Pharmaceuticals in East Hanover, New Jersey, and Ko holds stock in Novartis.

However, the influence of smoking habit and histological type on tumor-infiltrating lymphocytes (TILs) in NSCLC remains unclear. We evaluated the prognostic significance of TILs (CD4 + , CD8 + , CD20 + , and FOXP3 + ) according to histological type and smoking habit using automatic immunohistochemical staining and cell counting in 218 patients with NSCLC. In multivariate survival analyses of clinical, pathological, and immunological factors, a high ratio of FOXP3 + to CD4 + T cells (FOXP3/CD4) [hazard ratio (HR): 4.46, P < 0.01 for overall survival (OS); HR: 1.96, P < 0.05 for recurrence-free survival (RFS)] and a low accumulation of CD20 + B cells (HR: 2.45, P = 0.09 for OS; HR: 2.86, P < 0.01 for RFS) were identified as worse prognostic factors in patients with adenocarcinoma (AD). In non-AD, a low number of CD8 + T cells were correlated with an unfavorable outcome (HR: 7.69, P < 0.01 for OS; HR: 3.57, P < 0.02 for RFS). Regarding smoking habit in AD, a high FOXP3/CD4 ratio was poorly prognostic with a smoking history (HR: 5.21, P < 0.01 for OS; HR: 2.38, P < 0.03 for RFS), whereas a low accumulation of CD20 + B cells (HR: 4.54, P = 0.03 for OS; HR: 2.94, P < 0.01 for RFS) was confirmed as an unfavorable factor in non-smokers with AD. A low number of CD8 + T cells in non-AD, a high FOXP3/CD4 ratio in smokers with AD, and a low number of CD20 + B cells in non-smokers with AD were identified as independent unfavorable prognostic factors in resected NSCLC. Evaluating the influence of histological type and smoking habit on the immunological environment may lead to the establishment of immunological diagnosis and appropriate individualized immunotherapy for NSCLC. © The Author 2016.

Aberrant expression of the secreted protein, acidic, cysteine-rich (osteonectin) (SPARC) gene, which encodes a matricellular protein that participates in normal tissue remodeling, is associated with a variety of diseases including cancer, but the contribution of SPARC to malignant growth remains controversial. We previously reported that SPARC was among the most upregulated genes in cytogenetically normal acute myeloid leukemia (CN-AML) patients with gene-expression profiles predictive of unfavorable outcome, such as mutations in isocitrate dehydrogenase 2 (IDH2-R172) and overexpression of the oncogenes brain and acute leukemia, cytoplasmic (BAALC) and v-ets erythroblastosis virus E26 oncogene homolog (ERG). In contrast, SPARC was downregulated in CN-AML patients harboring mutations in nucleophosmin (NPM1) that are associated with favorable prognosis. Based on these observations, we hypothesized that SPARC expression is clinically relevant in AML. Here, we found that SPARC overexpression is associated with adverse outcome in CN-AML patients and promotes aggressive leukemia growth in murine models of AML. In leukemia cells, SPARC expression was mediated by the SP1/NF-κB transactivation complex. Furthermore, secreted SPARC activated the integrin-linked kinase/AKT (ILK/AKT) pathway, likely via integrin interaction, and subsequent β-catenin signaling, which is involved in leukemia cell self-renewal. Pharmacologic inhibition of the SP1/NF-κB complex resulted in SPARC downregulation and leukemia growth inhibition. Together, our data indicate that evaluation of SPARC expression has prognosticative value and SPARC is a potential therapeutic target for AML. PMID:24590286

We examine how changes in maternal work hours affect adolescent children's school participation and performance outcomes using data from interviews in 1998 and 2001 with approximately 1700 women who, in May 1995, were welfare-reliant, single mothers of adolescents living in neighborhoods of concentrated poverty in Cuyahoga (Cleveland), Los Angeles, Miami-Dade, and Philadelphia counties. Analyses control for a broad array of mothers' characteristics, including their psychological and physical health, experiences with domestic violence and substance abuse, as well as unobserved time-invariant characteristics. In fixed-effects models, we find unfavorable effects of increased maternal work hours on three of six outcomes: skipping school, performing above average, and parental contact about behavior problems. Adolescent-aged sons seem to be particularly sensitive to changes in mothers' hours of work.

The potential imbalance between malpractice liability cost and quality of care has been an issue of debate. We investigated the association of malpractice liability with unfavorable outcomes and increased hospitalization charges in cranial neurosurgery. We performed a retrospective cohort study involving patients who underwent cranial neurosurgical procedures from 2005-2010, and were registered in the National Inpatient Sample (NIS) database. We used data from the National Practitioner Data Bank (NPDB) from 2005 to 2010 to create measures of volume and size of malpractice claim payments. The association of the latter with the state-level mortality, length of stay (LOS), unfavorable discharge, and hospitalization charges for cranial neurosurgery was investigated. During the study period, there were 189,103 patients (mean age 46.4 years, with 48.3% females) who underwent cranial neurosurgical procedures, and were registered in NIS. In a multivariable regression, higher number of claims per physician in a state was associated with increased ln-transformed hospitalization charges (beta 0.18; 95% CI, 0.17 to 0.19). On the contrary, there was no association with mortality (OR 1.00; 95% CI, 0.94 to 1.06). We observed a small association with unfavorable discharge (OR 1.09; 95% CI, 1.06 to 1.13), and LOS (beta 0.01; 95% CI, 0.002 to 0.03). The size of the awarded claims demonstrated similar relationships. The average claims payment size (ln-transformed) (Pearson's rho=0.435, P=0.01) demonstrated a positive correlation with the risk-adjusted hospitalization charges but did not demonstrate a correlation with mortality, unfavorable discharge, or LOS. In the present national study, aggressive malpractice environment was not correlated with mortality but was associated with higher hospitalization charges after cranial neurosurgery. In view of the association of malpractice with the economics of healthcare, further research on its impact is necessary.

Cleft lip and palate (CLP) is one of the most common birth defects. Multiple factors are believed to be responsible for an unfavorable dental arch relationship in CLP. Facial growth (maxillary) retardation, which results in class III malocclusion, is the primary challenge that CLP patients face. Phenotype factors and postnatal treatment factors influence treatment outcomes in unilateral cleft lip and palate (UCLP) children, which has led to a great diversity in protocols and surgical techniques by various cleft groups worldwide. The aim of this study was to illustrate the dental arch relationship (DAR) and palatal morphology (PM) of UCLP in Bangladeshi children and to explore the various factors that are responsible for poor DAR and PM. Dental models of 84 subjects were taken before orthodontic treatment and alveolar bone grafting. The mean age was 7.69 (SD 2.46) years. The DAR and PM were assessed blindly by five raters using the EUROCRAN index (EI). Kappa statistics was used to evaluate the intra- and inter-examiner agreement, chi square was used to assess the associations, and logistic regression analysis was used to explore the responsible factors that affect DAR and PM. The mean EUROCRAN scores were 2.44 and 1.93 for DAR and PM, respectively. Intra- and inter-examiner agreement was moderate to very good. Using crude and stepwise backward regression analyses, significant associations were found between the modified Millard technique (P = 0.047, P = 0.034 respectively) of cheiloplasty and unfavorable DAR. Complete UCLP (P = 0.017) was also significantly correlated with unfavorable DAR. The PM showed a significant association with the type of cleft, type of cheiloplasty and type of palatoplasty. This multivariate study determined that the complete type of UCLP and the modified Millard technique of cheiloplasty had significantly unfavorable effects on both the DAR and PM.

Extreme body composition demands of competitive bodybuilding have been associated with unfavorable physiological changes, including alterations in metabolic rate and endocrine profile. The current case study evaluated the effects of contest preparation (8 months), followed by recovery (5 months), on a competitive drug-free male bodybuilder over 13 months (M1-M13). Serum testosterone, triiodothyronine (T 3 ), thyroxine (T 4 ), cortisol, leptin, and ghrelin were measured throughout the study. Body composition (BodPod, dualenergy x-ray absorptiometry [DXA]), anaerobic power (Wingate test), and resting metabolic rate (RMR) were assessed monthly. Sleep was assessed monthly via the Pittsburgh Sleep Quality Index (PSQI) and actigraphy. From M1 to M8, testosterone (623-173 ng∙dL -1 ), T 3 (123-40 ng∙dL -1 ), and T 4 (5.8-4.1 mg∙dL -1 ) decreased, while cortisol (25.2-26.5 mg∙dL -1 ) and ghrelin (383-822 pg∙mL -1 ) increased. The participant lost 9.1 kg before competition as typical energy intake dropped from 3,860 to 1,724 kcal∙day -1 ; BodPod estimates of body fat percentage were 13.4% at M1, 9.6% at M8, and 14.9% at M13; DXA estimates were 13.8%, 5.1%, and 13.8%, respectively. Peak anaerobic power (753.0 to 536.5 Watts) and RMR (107.2% of predicted to 81.2% of predicted) also decreased throughout preparation. Subjective sleep quality decreased from M1 to M8, but objective measures indicated minimal change. By M13, physiological changes were largely, but not entirely, reversed. Contest preparation may yield transient, unfavorable changes in endocrine profile, power output, RMR, and subjective sleep outcomes. Research with larger samples must identify strategies that minimize unfavorable adaptations and facilitate recovery following competition.

Several religions recommend periods of fasting. One of the most frequently asked questions of MS patients before the holy month of Ramadan is weather fasting might have an unfavorable effect on their disease course. This debate became more challenging after the publication of experimental studies suggesting that calorie restriction prior to disease induction attenuates disease severity. We conducted this study to assess early and late effects of fasting on the animal model of MS, known as autoimmune encephalomyelitis. EAE was induced in the C57BL/6 mice, using Myelin Oligodendrocyte Glycopeptide  (MOG) 35-55 and they fasted every other day either after the appearance of the first clinical sign or 30 days after disease induction for ten days. Thereafter, the mice were sacrificed for further histological and immunological evaluations. Intermittent fasting after the establishment of EAE did not have any unfavorable effect on the course of disease. Moreover, fasting at the early phase of disease alleviated EAE severity by ameliorating spinal cord demyelination. Fasting suppressed the secretion of IFN-γ, TNF-α and raised IL-10 production in splenocytes. Fasting was also associated with a lower percent of cytotoxicity. Intermittent fasting not only had no unfavorable effect on EAE but also reduced EAE severity if started at early phase of disease.

Dietary rapeseed (canola) oil (CO) given as the only fat nutrient shortens life in stroke-prone spontaneously hypertensive rats (SHRSP), compared with SHRSP given soybean oil (SO) instead of CO. CO ingestion increases plasma lipids and causes renal lesions in SHRSP and in spontaneously hypertensive rats (SHR), and increases plasma lipids also in Wistar Kyoto (WKY) rats, a normotensive counterpart of SHR. This study examined whether or not such unfavorable effects of CO are restricted to these closely related strains. For this purpose Wistar rats, the strain from which these strains were derived, were fed a diet containing 10% CO or SO as the sole fat nutrient for 10 weeks, and changes in clinical signs, urinalysis, blood biochemistry and pathology were compared. CO ingestion did not induce any abnormalities in Wistar rats, except significant increases in plasma concentrations of aldosterone and Na(+), compared with the SO group. Thus, the unfavorable effects of CO ingestion appear to be restricted to SHRSP and its closely related strains. The role of increased aldosterone and Na(+ )in the unfavorable events caused by CO in SHRSP, SHR and WKY rats, and any factors which could induce such increases in aldosterone and Na(+), remain to be elucidated.

Purpose: Radiotherapy (RT) is a common treatment of head-and-neck carcinoma. The objective of this study was to perform a prospective multivariate assessment of the dose-effect relationship between intensity-modulated RT and hearing loss. Methods and Materials: Pure tone audiometry at 0.250-16 kHz was obtained before and after treatment in 101 patients (202 ears). All patients received full-course intensity-modulated RT (range, 56-70 Gy), with a median cochlear dose of 11.4 Gy (range, 0.2-69.7). Results: Audiometry was performed 1 week before and a median of 9 weeks (range, 1-112) after treatment. The mean hearing deterioration at pure tone average air-conduction 1-2-4 kHz wasmore » small (from 28.6 dB HL to 30.1 dB HL). However, individual patients showed clinically significant hearing loss, with 10-dB threshold shift incidences of 13% and 18% at pure tone averages air-conduction 1-2-4 kHz and 8-10-12.5 kHz, respectively. Post-treatment hearing capability was unfavorable in the case of greater inner ear radiation doses (p <0.0001), unfavorable baseline hearing capability (p <0.0001), green-eyed patients (p <0.0001), and older age (p <0.0001). Using multivariate analysis, a prediction of individual hearing capabiltity after treatment was made. Conclusion: RT-induced hearing loss in the mean population is modest. However, clinically significant hearing loss was observed in older patients with green eyes and unfavorable pretreatment hearing. In these patients, the intended radiation dose may be adjusted according to the proposed predictive model, aiming to decrease the risk of ototoxicity.« less

We aimed to determine whether serum soluble CD30 (sCD30) could identify recipients at high risk for unfavorable early and late kidney transplant outcomes. Serum sCD30 was measured on the day of kidney transplantation and on the 4th day posttransplant. We assessed the value of these measurements in predicting delayed graft function, slow graft function (SGF), acute rejection (AR), pyelonephritis, decline of allograft function after 6 months, and graft and patient survival during 5 years of follow-up in 45 recipients. We found the association between low pretransplant serum levels of sCD30 and SGF. The absence of significant decrease of sCD30 on the 4th day posttransplant was characteristic for SGF, early AR (the 8th day-6 months), late AR (>6 months), and early pyelonephritis (the 8th day-2 months). Lower pretransplant and posttransplant sCD30 predicted worse allograft function at 6 months and 2 years, respectively. Higher pretransplant sCD30 was associated with higher frequency of early AR, and worse patients' survival, but only in the recipients of deceased-donor graft. Pretransplant sCD30 also allowed to differentiate patients with early pyelonephritis and early AR. Peritransplant sCD30 is useful in identifying patients at risk for unfavorable early and late transplant outcomes.

The main concern with whiplash is that a large proportion of whiplash patients experience disabling symptoms or whiplash-associated disorders (WAD) for months if not years following the accident. Therefore, identifying early prognostic factors of WAD development is important as WAD have widespread clinical and economic consequences. In order to tackle that question, our study was specifically aimed at combining several methods of investigation in the same WAD patients at the acute stage and 6 months later. Our longitudinal, open, prospective, multi-center study included 38 whiplash patients, and 13 healthy volunteers matched for age, gender, and socio-economic status with the whiplash group. Whiplash patients were evaluated 15–21 days after road accident, and 6 months later. At each appointment, patients underwent a neuropsychological evaluation, a full clinical neurological examination, neurophysiological and postural tests, oto-neurological tests, cervical spine cord magnetic resonance imaging (MRI) with tractography (DTI). At 6 months, whiplash patients were categorized into two subgroups based on the results of the Diagnostic and Statistical Manual of Mental Disorders as having either favorable or unfavorable progression [an unfavorable classification corresponding to the presence of post-concussion symptom (PCS)] and we searched retrospectively for early prognostic factors of WAD predicting the passage to chronicity. We found that patients displaying high level of catastrophizing at the acute stage and/or post-traumatic stress disorder associated with either abnormalities in head or trunk kinematics, abnormal test of the otolithic function and at the Equitest or a combination of these syndromes, turned to chronicity. This study suggests that low-grade whiplash patients should be submitted as early as possible after the trauma to neuropsychological and motor control tests in a specialized consultation. In addition, they should be evaluated by a neuro-otologist for a detailed examination of vestibular functions, which should include cervical vestibular evoked myogenic potential. Then, if diagnosed at risk of WAD, these patients should be subjected to an intensive preventive rehabilitation program, including vestibular rehabilitation if required. PMID:27812348

Objective: To examine whether resilience has a protective effect in difficult work environments. Methods: A survey of 2063 individuals measured individual resilience, stress, burnout, sleep problems, likelihood of depression, job satisfaction, intent to quit, absences, and productivity. It also measured work characteristics: job demands, job influence, and social support. Multivariate and logistic regression models examined the main effects and interactions of resilience and job characteristics. Results: High strain work environments (high demand, low influence, and low support) have an unfavorable effect on all outcomes. Resilience has a protective effect on all outcomes. For stress, burnout, and sleep, higher resilience has a more protective effect under low-strain conditions. For depression, absence and productivity, resilience has a more protective effect when job strain is high. Conclusions: Workers with high resilience have better outcomes in difficult work environments. PMID:28002352

2012-07-01

Purpose: Treatment response in cancer has been monitored by measuring anatomic tumor volume (ATV) at various times without considering the inherent functional tumor heterogeneity known to critically influence ultimate treatment outcome: primary tumor control and survival. This study applied dynamic contrast-enhanced (DCE) functional MRI to characterize tumors' heterogeneous subregions with low DCE values, at risk for treatment failure, and to quantify the functional risk volume (FRV) for personalized early prediction of treatment outcome. Methods and Materials: DCE-MRI was performed in 102 stage IB{sub 2}-IVA cervical cancer patients to assess tumor perfusion heterogeneity before and during radiation/chemotherapy. FRV represents the totalmore » volume of tumor voxels with critically low DCE signal intensity (<2.1 compared with precontrast image, determined by previous receiver operator characteristic analysis). FRVs were correlated with treatment outcome (follow-up: 0.2-9.4, mean 6.8 years) and compared with ATVs (Mann-Whitney, Kaplan-Meier, and multivariate analyses). Results: Before and during therapy at 2-2.5 and 4-5 weeks of RT, FRVs >20, >13, and >5 cm{sup 3}, respectively, significantly predicted unfavorable 6-year primary tumor control (p = 0.003, 7.3 Multiplication-Sign 10{sup -8}, 2.0 Multiplication-Sign 10{sup -8}) and disease-specific survival (p = 1.9 Multiplication-Sign 10{sup -4}, 2.1 Multiplication-Sign 10{sup -6}, 2.5 Multiplication-Sign 10{sup -7}, respectively). The FRVs were superior to the ATVs as early predictors of outcome, and the differentiating power of FRVs increased during treatment. Discussion: Our preliminary results suggest that functional tumor heterogeneity can be characterized by DCE-MRI to quantify FRV for predicting ultimate long-term treatment outcome. FRV is a novel functional imaging heterogeneity parameter, superior to ATV, and can be clinically translated for personalized early outcome prediction before or as early as 2-5 weeks into treatment.« less

Trust in decision-making authorities dictates the form of the interactive relationship between outcome fairness and procedural fairness.

Reactions to decisions are shaped by both outcome and procedural fairness. Moreover, outcome and procedural fairness interact to influence beliefs and behaviors. However, different types of "process/outcome" interaction effects have emerged. Many studies have shown that people react particularly negatively when they receive unfair or unfavorable outcomes accompanied by unfair procedures (the "low-low" interactive pattern). However, others find that people react especially positively when they receive fair or favorable outcomes accompanied by fair procedures (the "high-high" interactive pattern). We propose that trust in decision-making authorities dictates the form of the process/outcome interaction. Across three studies, when trust was high, the "low-low" interactive pattern emerged. When trust was low, the "high-high" interactive pattern emerged. The findings suggest that when people's experience of outcome and procedural fairness diverged from how they expected to be treated, they reacted in the direction of their experiences; otherwise, their reactions were consistent with their expectations. © 2014 by the Society for Personality and Social Psychology, Inc.

The lectin pathway of the complement system has been implicated in secondary ischemic/inflammatory injury after traumatic brain injury (TBI). However, previous experimental studies have yielded conflicting results, and human studies are scarce. In this exploratory study, we investigated associations of several lectin pathway proteins early after injury and single-nucleotide polymorphisms (SNP) with outcomes after severe TBI (mortality at 14 days [primary outcome] and consciousness assessed with the Glasgow Coma Scale [GCS] at 14 days, disability assessed with the Glasgow Outcome Scale Extended [GOSE] at 90 days). Forty-four patients with severe TBI were included. Plasma levels of lectin pathway proteins were sampled at 6, 12, 24, and 48 h after injury and eight mannose-binding lectin (MBL) and ficolin (FCN)2 SNPs were analyzed by enzyme-linked immunosorbent assay (ELISA) and genotyping, respectively. Plasma protein levels were stable with only a slight increase in mannose-binding protein-associated serine protease (MASP)-2 and FCN2 levels after 48 h (p < 0.05), respectively. Neither lectin protein plasma levels (6 h or mean levels) nor MBL2 genotypes or FCN2 variant alleles were associated with 14 day mortality or 14 day consciousness. However, FCN2, FCN3, and MASP-2 levels were higher in patients with an unfavorable outcome (GOSE 1-4) at 90 days (p < 0.05), whereas there was no difference in MBL2 genotypes or FCN2 variant alleles. In particular, higher mean MASP-2 levels over 48 h were independently associated with a GOSE score < 4 at 90 days after adjustment (odds ratio 3.46 [95% confidence interval 1.12-10.68] per 100 ng/mL increase, p = 0.03). No association was observed between the lectin pathway of the complement system and 14 day mortality or 14 day consciousness. However, higher plasma FCN2, FCN3, and, in particular, MASP-2 levels early after injury were associated with an unfavorable outcome at 90 days (death, vegetative state, and severe disability) which may be related to an increased activation of the lectin pathway.

Our prospective randomized study evaluating stem stability (Roentgen stereophotogrammetric analysis, dual-energy x-ray absorptiometry) and clinical outcomes between the K2/Apex hip systems was ceased early because of a withdrawal of the stems which had an unfavorably high early revision rate reported in the Australian Orthopaedic Association National Joint Registry (9.3% at 3 years). At 2 years, there are no clinical differences between the stems. Roentgen stereophotogrammetric analysis has identified a high proportion of potentially concerning subsidence and retroversion in both groups, more marked in the K2 stem, although mostly in asymptomatic patients. Dual-energy x-ray absorptiometry has shown similar bone density around the stems. Retrieval analysis of 3 study patients showed fretting corrosion of the antirotation pin and aseptic lymphocyte-dominated vasculitis-associated lesion, with no relationship to bearing type or size. Analysis of 7 further nonstudy K2/Apex stems confirmed similar corrosion. This study shows potentially concerning subsidence of both stems and is the first to describe corrosion at the neck-stem interface and a relationship to metal-related pathology.

The prognostic value of pretreatment neutrophil-to-lymphocyte ratio (NLR) in cervical cancer remains controversial. We conducted a meta-analysis based on the data from 13 studies with 3729 patients to evaluate the association between the pretreatment NLR and the clinical outcomes of overall survival and progression-free survival in patients with cervical cancer. The relationship between NLR and clinicopathological parameters was also assessed. Hazard ratio (HR) or odds ratio (OR) with its 95% confidence interval (CI) was used as the effect size estimate. Our analysis indicated that elevated pretreatment NLR was a poor prognostic marker for patients with cervical cancer because it predicted unfavorable overall survival (HR = 1.375, 95% CI: 1.200-1.576) and progression-free survival (HR = 1.646, 95% CI: 1.313-2.065). Increased NLR is also significantly associated with the larger tumor size (OR = 1.780, 95% CI: 1.090-2.908), advanced clinical stage (OR = 2.443, 95% CI: 1.730-3.451), and positive lymph node metastasis (OR = 2.380, 95% CI: 1.775-3.190). By these results, high pretreatment NLR predicted a shorter survival period for patients with cervical cancer, and it could be served as a novel index of prognostic evaluation in patients with cervical cancer.

Dialysis vascular access management in the United States changed significantly after National Kidney Foundation-Kidney Disease Outcome Quality Initiative (NKF-KDOQI) clinical practice guidelines were first published in 1997. The Centers for Medicare and Medicaid Service adopted these guidelines and in collaboration with the End-Stage Renal Disease Networks established the Fistula First Breakthrough Initiative (FFBI) in 2003 to improve the rate of arteriovenous fistula use over arteriovenous graft and central venous catheter in the dialysis population. The implementation of guidelines and FFBI has led to a significant increase in the arteriovenous fistula use in the prevalent dialysis population. The guidelines are criticized for being opinion based and often impractical. Over the past 2 decades, the patient population undergoing dialysis has become older with complex comorbidities and challenges for creating an ideal vascular access. Advancing knowledge about access pathophysiology, improved treatment options, and improved process of care with team approach model point toward diminishing relevance of few of the existing guidelines. Moreover, several guidelines remain controversial and may be leading to clinical decisions that may be unfavorable to the patients. The review discusses the historical aspect of vascular access care in the United States and evolution of current practice standards and controversies surrounding few of these guidelines in the current time.

Analysis of occurrence of the third type secretory system (TTSS) effectors in clinical P. aeruginosa strains. Intra-hospital (n = 164) and extra-hospital (n = 30) strains of P. aeruginosa were studied. Detection of exoS and exoU genes was carried out by PCR in DNA Engine Dyad Thermal Cycler ("Bio-Rad", USA). Metallo-beta-lactamase (MBL) producers were detected by the presence of blaVIM-2 gene. Screening of intra- and extra-hospital strains for the presence of genes coding ExoS and ExoU showed, that exoS is detected in genome of clinical isolates in 59.8% and exoU--31.1% of cases. At the same time, strains with exoS-/exoU+ genotype predominated in lCU (Φ = 0.466; p = 0.0000). A significant association between the presence of the respective effectors and material of strain isolation was not detected. exoU gene was more frequently detected in genome of MBL producers (Φ = 0.784; p = 0.0004). A significant association between exoU and blaVIM-2 could be explained by clonal prevalence of P. aeruginosa ST235 VIM-2, circulation of those is noted on all the territory of Russia. As a rule, ExoU is produced by highly virulent poly-antibiotic resistant hospital isolates that determine unfavorable outcomes of pseudomonas infection.

To investigate the predictive value of overgeneral memory (OGM) for outcome of electroconvulsive therapy (ECT) for depression. The Autobiographical Memory Test was used to measure OGM in 25 patients with depression before ECT. The Hamilton Rating Scale for Depression (HRSD) was administered weekly to 1 week posttreatment. Overgeneral memory did not predict HRSD scores from the last ECT treatment, but did predict HRSD change scores from the last treatment to 1-week follow-up: patients high in OGM experienced a relatively greater increase in HRSD scores after the last treatment. Results further extend the status of OGM as a predictor of an unfavorable course of depression to a previously unstudied ECT population.

Objective The magnitude and role of the cellular immune response following pediatric traumatic brain injury (TBI) remains unknown. We tested the hypothesis that macrophage/microglia and T-cell activation occurs following pediatric TBI by measuring cerebrospinal fluid (CSF) levels of sCD163 and ferritin, and sIL-2Rα, respectively, and determined whether these biomarkers were associated with relevant clinical variables and outcome. Design Retrospective analysis of samples from an established, single-center CSF bank. Setting Pediatric Intensive Care Unit (PICU) in a tertiary Children’s Hospital Patients Sixty-six pediatric patients after severe TBI (Glasgow coma scale score [GCS]<8) age 1 mo-16 y and 17 control patients age 1 mo-14 y. Measurements and Main Results CSF levels of sCD163, ferritin, and sIL-2Rα were determined by ELISA at 2 time points (t1=17±10, t2=72±15 h) for each TBI patient. CSF sCD163, ferritin, and sIL2Rα levels after TBI were compared with controls and analyzed for associations with age, patient sex, initial GCS, diagnosis of abusive head trauma (AHT), the presence of hemorrhage on computerized tomography scan, and Glasgow outcome scale score (GOS). CSF sCD163 was increased in TBI patients at t2 vs. t1 and controls (95.4[21.8–134.0] vs. 31.0[5.7–77.7] and 27.8[19.1–43.1] ng/ml, respectively; median[IQ]; P<0.05). CSF ferritin was increased in TBI patients at t2 and t1 vs. controls (8.3[7.5–19.8] and 8.9[7.5–26.7] vs. [7.5[0.0–0.0] ng/ml, respectively; P<0.05). CSF sIL-2Rα in TBI patients at t2 and t1 were not different vs. controls. Multivariate regression revealed associations between high ferritin and age ≤ 4 y, lower GCS, AHT, and unfavorable GOS. Conclusions Children with TBI demonstrate evidence for macrophage activation after TBI, and in terms of CSF ferritin, this appears more prominent with young age, initial injury severity, AHT, and unfavorable outcome. Further study is needed to determine whether biomarkers of macrophage activation may be used to discriminate between aberrant and adaptive immune responses, and whether inflammation represents a therapeutic target after TBI.

This work aims to gain insight into the long-term impact of depression course on social network size and perceived loneliness in older people living in the community. Within a large representative sample of older people in the community (Longitudinal Aging Study Amsterdam (LASA)), participants with clinically relevant levels of depressive symptoms (scores >16 on the Center for Epidemiological Studies Depression Scale) were followed up over a period of 13 years of the LASA study (five waves). General estimating equations were used to estimate the impact of depression course on network size and loneliness and the interaction with gender and age. An unfavorable course of depression was found to be associated with smaller network sizes and higher levels of loneliness over time, especially in men and older participants. The findings of this study stress the importance of clinical attention to the negative consequences of chronicity in depressed older people. Clinicians should assess possible erosion of the social network over time and be aware of increased feelings of loneliness in this patient group. Copyright © 2014 John Wiley & Sons, Ltd.

Objectives: To describe the clinical encounters that occur when a palliative care team provides patient care and the features that influence these encounters and indicate whether they are favorable or unfavorable depending on the expectations and feelings of the various participants. Methods: A qualitative case study conducted via participant observation. A total of 12 observations of the meetings of palliative care teams with patients and families in different settings (home, hospital and consultation room) were performed. The visits were follow-up or first visits, either scheduled or on demand. Content analysis of the observation was performed. Results: The analysis showed the normal follow-up activity of the palliative care unit that was focused on controlling symptoms, sharing information and providing advice on therapeutic regimens and care. The environment appeared to condition the patients' expressions and the type of patient relationship. Favorable clinical encounter conditions included kindness and gratitude. Unfavorable conditions were deterioration caused by approaching death, unrealistic family objectives and limited resources. Conclusion: Home visits from basic palliative care teams play an important role in patient and family well-being. The visits seem to focus on controlling symptoms and are conditioned by available resources. PMID:27226663

Bipolar disorder (BD) is a chronic, frequently comorbid condition characterized by high rates of mood episode recurrence and suicidality. Little is known about prospective longitudinal characterization of BD type II (BD II) versus type I (BD I) in relation to time to depressive recurrence and recovery from major depressive episode. We therefore assessed times to depressive recurrence/recovery in tertiary clinic-referred BD II versus I patients. Outpatients referred to Stanford BD Clinic during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and with Clinical Monitoring Form during up to 2 years of naturalistic treatment. Prevalence and clinical correlates of bipolar subtype in recovered (euthymic ≥8 weeks) and depressed patients were assessed. Kaplan-Meier analyses assessed the relationships between bipolar subtype and longitudinal depressive severity, and Cox proportional hazard analyses assessed the potential mediators. BD II versus BD I was less common among 105 recovered (39.0 vs. 61.0%, p = 0.03) and more common among 153 depressed (61.4 vs. 38.6%, p = 0.006) patients. Among recovered patients, BD II was associated with 6/25 (24.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics and hastened depressive recurrence (p = 0.015). Among depressed patients, BD II was associated with 8/25 (33.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics, but only non-significantly associated with delayed depressive recovery. BD II versus BD I was significantly associated with current depression and hastened depressive recurrence, but only non-significantly associated with delayed depressive recovery. Research on bipolar subtype relationships with depressive recurrence/recovery is warranted to enhance clinical management of BD patients.

Although long-term neurological outcomes after traumatic brain injury (TBI) sustained early in life are generally unfavorable, the effect of TBI on the development of academic competencies is unknown. The present study characterizes intelligence quotient (IQ) and academic outcomes an average of 5.7 years after injury in children who sustained moderate to severe TBI prior to 6 years of age. Twenty-three children who suffered inflicted or noninflicted TBI between the ages of 4 and 71 months were enrolled in a prospective, longitudinal cohort study. Their mean age at injury was 21 months; their mean age at assessment was 89 months. The authors used general linear modeling approaches to compare IQ and standardized academic achievement test scores from the TBI group and a community comparison group (21 children). Children who sustained early TBI scored significantly lower than children in the comparison group on intelligence tests and in the reading, mathematical, and language domains of achievement tests. Forty-eight percent of the TBI group had IQs below the 10th percentile. During the approximately 5-year follow-up period, longitudinal IQ testing revealed continuing deficits and no recovery of function. Both IQ and academic achievement test scores were significantly related to the number of intracranial lesions and the lowest postresuscitation Glasgow Coma Scale score but not to age at the time of injury. Nearly 50% of the TBI group failed a school grade and/or required placement in self-contained special education classrooms; the odds of unfavorable academic performance were 18 times higher for the TBI group than the comparison group. Traumatic brain injury sustained early in life has significant and persistent consequences for the development of intellectual and academic functions and deleterious effects on academic performance.

Background Studies of liver donors’ psychosocial outcomes focus on the short-term and rely largely on quality-of-life measures not specific to donation. We sought to examine long-term donation effects on three psychosocial domains: perceived physical, emotional, and socioeconomic outcomes. Methods Individuals donating 3–10 years previously at nine centers were eligible for telephone surveys. Survey responses were examined descriptively. Cluster analysis was used to identify distinct donor groups based on response profiles across psychosocial domains. Potential predictors of response profiles were evaluated with regression analysis. Results 517 donors (66%) participated (M=5.8 years postdonation, SD=1.9). 15%–48% of donors endorsed current donation-related physical health problems and concerns, and 7%–60% reported socioeconomic concerns (e.g., insurance difficulties, financial expenditures). However, on average, donors experienced high psychological growth, and 90% felt positively about donation. Cluster analysis revealed five donor groups. One group showed high psychological benefit, with little endorsement of physical or socioeconomic concerns (15% of donors). Four groups showed less favorable profiles, with varying combinations of difficulties. The largest such group showed high endorsement of physical concerns and financial expenditures, and only modest psychological benefit (31% of donors). Men and non-Hispanic whites were most likely to have unfavorable response profiles (p<.01). Compared with donors aged 19–30, older donors were less likely to have unfavorable profiles; these differences were significant for donors aged >40–50 (p’s<.008). Conclusions Even many years postdonation, donors report adverse physical and socioeconomic effects, but positive emotional effects as well. Identification of response profiles and predictors may improve targeting of postdonation surveillance and care. PMID:27152918

Hyperglycemia on admission is common after ischemic stroke. It is associated with unfavorable outcome after treatment with intravenous thrombolysis and after intra-arterial treatment. Whether hyperglycemia influences the effect of reperfusion treatment is unknown. We assessed whether increased admission serum glucose modifies the effect of intra-arterial treatment in patients with acute ischemic stroke. We used data from the MR CLEAN (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands). Hyperglycemia was defined as admission serum glucose >7.8 mmol/L. The primary outcome measure was the adjusted common odds ratio for a shift in the direction of a better outcome on the modified Rankin Scale at 90 days, estimated with ordinal logistic regression. Secondary outcome variable was symptomatic intracranial hemorrhage. We assessed treatment effect modification of hyperglycemia and admission serum glucose levels with multiplicative interaction factors and adjusted for prognostic variables. Four hundred eighty-seven patients were included. Mean admission serum glucose was 7.2 mmol/L (SD, 2.2). Fifty-seven of 226 patients (25%) randomized to intra-arterial treatment were hyperglycemic compared with 61 of 261 patients (23%) in the control group. The interaction of either hyperglycemia or admission serum glucose levels and treatment effect on modified Rankin Scale scores was not significant ( P =0.67 and P =0.87, respectively). The same applied for occurrence of symptomatic hemorrhage ( P =0.39 for hyperglycemia, P =0.39 for admission serum glucose). We found no evidence for effect modification of intra-arterial treatment by admission serum glucose in patients with acute ischemic stroke. URL: www.isrctn.com.

Pretreatment tables for the prediction of pathologic stage have been published and validated for localized prostate cancer (PCa). No such tables are available for locally advanced (cT3a) PCa. To construct tables predicting pathologic outcome after radical prostatectomy (RP) for patients with cT3a PCa with the aim to help guide treatment decisions in clinical practice. This was a multicenter retrospective cohort study including 759 consecutive patients with cT3a PCa treated with RP between 1987 and 2010. Retropubic RP and pelvic lymphadenectomy. Patients were divided into pretreatment prostate-specific antigen (PSA) and biopsy Gleason score (GS) subgroups. These parameters were used to construct tables predicting pathologic outcome and the presence of positive lymph nodes (LNs) after RP for cT3a PCa using ordinal logistic regression. In the model predicting pathologic outcome, the main effects of biopsy GS and pretreatment PSA were significant. A higher GS and/or higher PSA level was associated with a more unfavorable pathologic outcome. The validation procedure, using a repeated split-sample method, showed good predictive ability. Regression analysis also showed an increasing probability of positive LNs with increasing PSA levels and/or higher GS. Limitations of the study are the retrospective design and the long study period. These novel tables predict pathologic stage after RP for patients with cT3a PCa based on pretreatment PSA level and biopsy GS. They can be used to guide decision making in men with locally advanced PCa. Our study might provide physicians with a useful tool to predict pathologic stage in locally advanced prostate cancer that might help select patients who may need multimodal treatment.

In cancer patients, who are frequently immunocompromised, bacterial meningitis (BM) can be a severe complication, with a different presentation, etiology, and course, compared to patients without cancer. Our objective is to compare the characteristics and outcomes of BM in patients with and without cancer. A single-center, prospective observational cohort study, conducted between 1982 and 2012, in a tertiary university hospital in Barcelona (Spain). The main outcome measure is in-hospital mortality. We evaluated 659 episodes of BM; 97 (15%) had active cancer. Patients with malignancies were older (median 63 (interquartile range [IQR] 24) vs 52 [IQR 42] years, P < .001) and more often had a Charlson comorbidity score of ≥3 (51% vs 11%, P < .001). The classic meningitis triad (35% vs 50%, P = .05), fever (91% vs 96%, P = .03), neck stiffness (58% vs 78%, P < .001), headache (63% vs 77%) P = .003), and rash (7% vs 30%, P < .001) were less frequent. There was a longer interval between admission and antibiotic therapy (median 5 [IQR 14] vs 3 [IQR 6] hours, P < .001). Listeria meningitis was the commonest cause of BM (29%) and was more frequent in cancer than noncancer (8%, P < .001) patients, whereas meningococcal meningitis was much less frequent (4% vs 36%, P < .001). Overall mortality was higher in patients with cancer (31% vs 16%, P < .001), although cancer was not associated with an unfavorable outcome in the multivariate analysis (odds ratio 1.825, P = .07). Patients with meningitis and cancer are older and have more subtle clinical manifestations than patients without cancer. Listeria monocytogenes is the predominant pathogen and mortality is higher in cancer patients.

Prostate Biopsy Specimens With Gleason 3+3=6 and Intraductal Carcinoma: Radical Prostatectomy Findings and Clinical Outcomes.

Although intraductal carcinoma of the prostate (IDC-P) is typically present on biopsies in which there is also invasive prostate carcinoma of Gleason pattern 4 or 5 and an associated unfavorable outcome, there are limited studies on IDC-P in needle core biopsies or transurethral resections (TURP) with only a concomitant low-grade invasive component. There are differing opinions on incorporating IDC-P into the Gleason score in such cases. The aim of this study was to investigate clinical outcomes and radical prostatectomy (RP) findings in patients with Gleason 3+3=6 and IDC-P on biopsy or TURP. We identified 73 patients in our consult files (2001 to 2014) who had IDC-P and Gleason score 6 carcinoma on biopsy or TURP with no invasive higher Gleason grade component. Clinical follow-up information was available in 62 patients. Treatment was RP in 14 patients, radiation therapy in 31 patients, androgen deprivation therapy in 1 patient, and cryotherapy in 1 patient. Four patients were found to have metastatic disease at the time of diagnosis and were treated with chemotherapy. Eleven patients underwent active surveillance after diagnosis, of which 6 were eventually treated for progressive disease. The 14 RP specimens were centrally reviewed, and 86% had extensive IDC-P present. The Gleason grades in these 14 RP cases were 3+3=6 in 21%, 3+4=7 in 36%, 4+3=7 in 29%, and 4+4=8 in 14%. Pathologic stage was pT2 in 36%, pT3a in 36%, and pT3b in 28%. After 3 years, there was a 20% actuarial rate of disease progression in men who underwent either RP or radiation therapy. In summary, most men with IDC-P on biopsy/TURP have aggressive tumors, even when the invasive tumor on biopsy is Gleason score 6. As a minority of men may only have Gleason 6 invasive cancer at RP and a favorable prognosis, we recommend that IDC-P on biopsy/TURP be reported separately and not assigned a Gleason score.

B cell lymphoma 2 (BCL-2) gene is a well-known regulator of apoptosis and a key element in cancer development and progression. A regulatory (-938C>A, rs2279115) single-nucleotide polymorphism in the inhibitory P2 BCL-2 gene promoter generates significantly different BCL-2 promoter activities and has been associated with different clinical outcomes in various malignancies. The aim of the present study was to analyze the possible influence of the (-938C>A) SNP on the risk and survival of Indian patients suffering from NSCLC. A hospital-based case-control study of 155 age- and sex-matched patients diagnosed with NSCLC and 155 cancer-free controls was conducted and genotyped by performing PIRA-PCR to elucidate the putative association between clinical outcome and genotypes of BCL-2 (-938C>A, rs2279115). The association of the polymorphism with the survival of NSCLC patients was analyzed by Kaplan-Meier curves. In Indian NSCLC, patients increased risk of developing NSCLC was found to be associated with BCL-2 (-938) CC genotype, [OR 3.68 (1.92-6.79), RR 1.87 (1.35-2.57) and RD 31.03 (16.79-45.27) p 0.00006 for CC and OR 2.08 (1.18-3.66), RR 1.36 (1.08-1.71) and RD 17.74 (4.68-30.81) p 0.01 for AC genotype]. Patients homozygous for C allele exhibited a significant poor overall survival compared with patients displaying AC + CC or AC or AA genotype [median survival (months) 8 vs. 11 vs. 14 vs. 35.5 (p < 0.0001)]. In addition, significant associations were observed between TNM stage, histological type, distant metastases status, family history of any cancer, gender and age group of NSCLC patients with BCL-2 (-938C>A) polymorphism. Genetic polymorphism in the inhibitory P2 promoter region of anti-apoptotic BCL-2 genes contributes to the risk of developing non-small-cell lung cancer in Indian population. BCL-2 (-938CC) genotype was an independent adverse prognostic factor for patients with NSCLC.

High blood pressure (BP) is associated with worse clinical outcomes in the setting of acute ischemic stroke, but the optimal blood pressure target is still a matter of debate. We aimed to study the association between baseline BP and mortality in acute ischemic stroke patients treated by mechanical thrombectomy. A total of 1332 acute ischemic stroke patients treated by mechanical thrombectomy were enrolled (from January 2012 to June 2016) in the ETIS (Endovascular Treatment in Ischemic Stroke) registry. Linear and polynomial logistic regression models were used to assess the association between BP and mortality and functional outcome at 90 days. Highest mortality was found at lower and higher baseline systolic blood pressure (SBP) values following a J- or U-shaped relationship, with a nadir at 157 mm Hg (95% confidence interval 143-170). When SBP values were categorized in 10-mm Hg increments, the odds ratio for all-cause mortality was 3.78 (95% confidence interval 1.50-9.55) for SBP<110 mm Hg and 1.81 (95% confidence interval 1.01-3.36) for SBP≥180 mm Hg using SBP≥150 to 160 mm Hg as reference. The rate of favorable outcome was the highest at low SBP values and lowest at high SBP values, with a nonlinear relationship; in unplanned exploratory analysis, an optimal threshold SBP≥177 mm Hg was found to predict unfavorable outcome (adjusted odds ratio 0.47; 95% confidence interval 0.31-0.70). In acute ischemic stroke patients treated by mechanical thrombectomy, baseline SBP is associated with all-cause mortality and favorable outcome. In contrast to mortality, favorable outcome rate was the highest at low SBP values and lowest at high SBP values. Further studies are warranted to confirm these findings. © 2017 The Authors.

Abstract Intraparenchymal hemorrhages occur in a proportion of severe traumatic brain injury TBI patients, but the role of surgery in their treatment is unclear. This international multi-center, patient-randomized, parallel-group trial compared early surgery (hematoma evacuation within 12 h of randomization) with initial conservative treatment (subsequent evacuation allowed if deemed necessary). Patients were randomized using an independent randomization service within 48 h of TBI. Patients were eligible if they had no more than two intraparenchymal hemorrhages of 10 mL or more and did not have an extradural or subdural hematoma that required surgery. The primary outcome measure was the traditional dichotomous split of the Glasgow Outcome Scale obtained by postal questionnaires sent directly to patients at 6 months. The trial was halted early by the UK funding agency (NIHR HTA) for failure to recruit sufficient patients from the UK (trial registration: ISRCTN19321911). A total of 170 patients were randomized from 31 of 59 registered centers worldwide. Of 82 patients randomized to early surgery with complete follow-up, 30 (37%) had an unfavorable outcome. Of 85 patients randomized to initial conservative treatment with complete follow-up, 40 (47%) had an unfavorable outcome (odds ratio, 0.65; 95% confidence interval, CI 0.35, 1.21; p=0.17), with an absolute benefit of 10.5% (CI, −4.4–25.3%). There were significantly more deaths in the first 6 months in the initial conservative treatment group (33% vs. 15%; p=0.006). The 10.5% absolute benefit with early surgery was consistent with the initial power calculation. However, with the low sample size resulting from the premature termination, we cannot exclude the possibility that this could be a chance finding. A further trial is required urgently to assess whether this encouraging signal can be confirmed. PMID:25738794

We evaluated gender-differences in quality of type 1 diabetes (T1DM) care. Starting from electronic medical records of 300 centers, 5 process indicators, 3 favorable and 6 unfavorable intermediate outcomes, 6 treatment intensity/appropriateness measures and an overall quality score were measured. The likelihood of women vs. men (reference class) to be monitored, to reach outcomes, or to be treated has been investigated through multilevel logistic regression analyses; results are expressed as Odd Ratios (ORs) and 95% confidence intervals (95%CIs). The inter-center variability in the achievement of the unfavorable outcomes was also investigated. Overall, 28,802 subjects were analyzed (45.5% women). Women and men had similar age (44.5±16.0 vs. 45.0±17.0 years) and diabetes duration (18.3±13.0 vs. 18.8±13.0 years). No between-gender differences were found in process indicators. As for intermediate outcomes, women showed 33% higher likelihood of having HbA1c ≥8.0% (OR = 1.33; 95%CI: 1.25-1.43), 29% lower risk of blood pressure ≥140/90 mmHg (OR = 0.71; 95%CI: 0.65-0.77) and 27% lower risk of micro/macroalbuminuria (OR = 0.73; 95%CI: 0.65-0.81) than men, while BMI, LDL-c and GFR did not significantly differ; treatment intensity/appropriateness was not systematically different between genders; overall quality score was similar in men and women. Consistently across centers a larger proportion of women than men had HbA1c ≥8.0%, while a smaller proportion had BP ≥140/90 mmHg. No gender-disparities were found in process measures and improvements are required in both genders. The systematic worse metabolic control in women and worse blood pressure in men suggest that pathophysiologic differences rather than the care provided might explain these differences.

EARLYDRAIN- outcome after early lumbar CSF-drainage in aneurysmal subarachnoid hemorrhage: study protocol for a randomized controlled trial

PubMed Central

2011-01-01

Background Aneurysmal subarachnoid hemorrhage (SAH) may be complicated by delayed cerebral ischemia, which is a major cause of unfavorable clinical outcome and death in SAH-patients. Delayed cerebral ischemia is presumably related to the development of vasospasm triggered by the presence of blood in the basal cisterns. To date, oral application of the calcium antagonist nimodipine is the only prophylactic treatment for vasospasm recognized under international guidelines. In retrospective trials lumbar drainage of cerebrospinal fluid has been shown to be a safe and feasible measure to remove the blood from the basal cisterns and decrease the incidence of delayed cerebral ischemia and vasospasm in the respective study populations. However, the efficacy of lumbar drainage has not been evaluated prospectively in a randomized controlled trial yet. Methods/Design This is a protocol for a 2-arm randomized controlled trial to compare an intervention group receiving early continuous lumbar CSF-drainage and standard neurointensive care to a control group receiving standard neurointensive care only. Adults suffering from a first aneurysmal subarachnoid hemorrhage whose aneurysm has been secured by means of coiling or clipping are eligible for trial participation. The effect of early CSF drainage (starting < 72 h after securing the aneurysm) will be measured in the following ways: the primary endpoint will be disability after 6 months, assessed by a blinded investigator during a personal visit or standardized telephone interview using the modified Rankin Scale. Secondary endpoints include mortality after 6 months, angiographic vasospasm, transcranial Doppler sonography (TCD) mean flow velocity in both middle cerebral arteries and rate of shunt insertion at 6 months after hospital discharge. Discussion Here, we present the study design of a multicenter prospective randomized controlled trial to investigate whether early application of a lumbar drainage improves clinical outcome after aneurysmal subarachnoid hemorrhage.

Childhood acute lymphoblastic leukemia (ALL) is a heterogeneous disease. Current treatment approaches are tailored according to the clinical features of the host, genotypic features of the leukemic blast, and early response to therapy. Although these approaches have been successful in dramatically improving outcomes, approximately 20% of children with ALL still relapse and many of these children do not have an identifiable adverse risk factor at presentation. Further insights into the biologic basis of the disease may contribute to novel, rational treatment strategies. Childhood ALL has served as an example for demonstrating the feasibility and potential of high-throughput technologies such as global gene expression or transcript profiling. In the last decade or so, utilization of these techniques has grown exponentially. As the methodology undergoes refinement and validation, it is plausible that microarrays may be used in the routine management of childhood ALL in the next few years. This article discusses the numerous applications to date of gene expression profiling in childhood ALL. Multiple investigators have made it evident that microarrays can be used as a single platform for the accurate classification of ALL into the various cytogenetic subtypes. Additional promising utilities include prediction of early response to therapy, overall outcome, and adverse effects. Identification of patients who are predicted to have an unfavorable outcome may allow for early intervention such as intensification of therapy or avoidance of drugs that are associated with specific secondary effects such as therapy-related acute myelogenous leukemia. Knowledge has been gained into pathways contributing to leukemogenesis and chemoresistance. Therapeutic targets have been identified, some of which are entering clinical trials following validation in additional preclinical models. These newer methods of genome analyses complemented by studies involving the proteome as well as host polymorphisms will have a profound impact on the diagnosis and management of childhood ALL.

Mild-to-moderate ulcerative colitis: your role in patient compliance and health care costs.

Ulcerative colitis (UC) is a chronic relapsing disease necessitating lifelong treatment. Most patients present with mild-to-moderate disease characterized by alternating periods of remission and clinical relapse. Continued disease progression and relapse of UC over time are associated with an increased risk of colorectal cancer (CRC). To discuss the latest treatment options for mild-to-moderate UC, to review the current data involving the economics of UC, and to demonstrate the relationship between treatment adherence, clinical relapse, inflammation severity, CRC risk, and treatment outcomes. One of the main goals of therapy in UC is to induce and maintain a long-lasting remission of disease to reduce or avoid the high personal and financial costs of relapse. In recent studies, researchers have demonstrated a link between increased colonic inflammation and CRC risk, highlighting the importance of preventing relapse, which can lead to costly surgical procedures and hospital stays and thus increase the cost of treatment 2- to 20-fold. The risk of disease relapse is affected by several factors, of which the most prominent is nonadherence to maintenance therapy. Nonadherence to therapy can be associated with several other factors, including forgetfulness, male sex, complicated dosing regimens, treatment delivery methods (oral vs. rectal), and pill burden. In the treatment of mild-to-moderate UC, 5-aminosalicyclic acid (5-ASA) is the standard first-line therapy and the treatment of choice for maintaining remission of disease. Novel formulations of 5-ASA and newly devised high-dose 5-ASA regimens offer more options for the treatment of UC and thus may lead to improved treatment adherence, longer remission, and improved patient well-being. Periods of remission during UC treatment must be aggressively maintained to prevent relapse and decrease the risk of an unfavorable outcome. By controlling the risks and conditions that lead to therapeutic nonadherence and relapse among patients with UC, clinicians can increase the likelihood of long-term remission and ensure favorable long-term outcomes.

Idiopathic pulmonary fibrosis (IPF), also known as cryptogenic fibrosing alveolitis, is one of a spectrum of idiopathic interstitial pneumonia. IPF is an increasingly common condition which poses many diagnostic and therapeutic challenges leading to misdiagnosis and mismanagement. We presented a 55-year-old male textile trader who was initially managed as sputum-negative pulmonary tuberculosis before histology report. He presented to our clinic with Breathlessness and cough of 3 years and 2.5 years, respectively. He had commenced anti-tuberculosis two months before presentation without significant relief. General Physical examination and vital signs were essentially normal. SPO2 was 96% on room air. Chest Examination revealed end-inspiratory bi-basal velcro-like crackles. Other systemic examinations were normal. Radiological examination by way of chest X- ray and chest CT showed features suggestive of IPF. The patient also had open Lung biopsy for histology and spirometry which demonstrated restrictive ventilatory function pattern. A diagnosis of Interstitial lung disease probably Idiopathic Pulmonary Fibrosis was entertained. He was commenced on Tab prednisolone, Tab Rabeprazole, with minimal improvement. IPF have often been misdiagnosed and treated as pulmonary tuberculosis with unfavorable outcome.

Hodgkin lymphoma (HL) has become one of the best curable malignancies today. This is particularly true for patients with early-stage disease. Today, most patients in this risk group are treated with a combination of chemotherapy followed by small-field radiotherapy. More recent clinical trials such as the German Hodgkin Study Group (GHSG) HD10 study demonstrated, that even two cycles of ABVD followed by 20 Gy involved-field radiation therapy (IF-RT) are sufficient and result in more than 90% of patients being cured. The current treatment for early unfavorable patients is either four cycles of ABVD plus 30 Gy IF-RT or two cycles of BEACOPPbaseline followed by two cycles of ABVD plus IF-RT. Here, the European Organization for Research and Treatment of Cancer (EORTC) demonstrated that in positron emission tomography (PET)-positive patients after two cycles of ABVD, treatment switched to two cycles of BEACOPPbaseline plus radiotherapy results in significantly improved outcomes. Other aspects including attempts to further reduce intensity of treatment will be discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

Best Practices for Pressure Ulcer Prevention in the Burn Center.

PubMed

Warner, Julia; Ann Raible, Mary; Hajduk, Gina; Collavo, Jacqueline

The State of Pennsylvania Hospital Engagement Network, in collaboration with a hospital system in Southwestern Pennsylvania, established a goal of reducing hospital-acquired pressure ulcers by 20%. A 6-month unfavorable trend of nurse-sensitive clinical indicators called for immediate process improvement. A retrospective chart review resulted in identification of predominant risk factors placing the burn patient at high risk for pressure ulcer formation. Implementations of pressure ulcer prevention measures were inconsistent. Nurses demonstrated varied levels of knowledge about products used for prevention. It became imperative to examine processes within the unit and provide nursing with education, access to skin care supplies, and advanced skin/wound care products for maintaining skin integrity. Creation of evidence-based guidelines was necessary to improve patient outcomes. A collaborative team approach influenced nursing and physician awareness of pressure ulcer risk. Evidence-based prevention guidelines were developed, and consistency in early intervention was achieved, supporting our culture of safety. A change in interprofessional collaborative practice and positive trend in pressure ulcer incidence data supports the success of our program.

Health care providers regularly encounter situations of moral conflict and distress in their practice. Moral distress may result in unfavorable outcomes for both health care providers and those in their care. The purpose of this study was to examine the experience of moral distress from a broad range of health care occupations that provide home-based palliative care as the initial step of addressing the issue. A critical incident approach was used in qualitative interviews to elicit the experiences on moral distress from 18 health care providers drawn from five home visiting organizations in south central Ontario, Canada. Most participants described at least two critical incidents in their interview generating a total of 47 critical incidents. Analyses of the critical incidents revealed 11 issues that triggered moral distress which clustered into three themes, (a) the role of informal caregivers, b) challenging clinical situations and (c) service delivery issues. The findings suggest that the training and practice environments for health care providers need to be designed to recognize the moral challenges related to day-to-day practice.

Amplification of the oncogene MYCN is a tumorigenic event in the development of a subset of neuroblastomas that commonly consist of undifferentiated or poorly differentiated neuroblasts with unfavorable clinical outcome. The cellular origin of these neuroblasts is unknown. Additionally, the cellular functions and target cells of MYCN in neuroblastoma development remain undefined. Here we examine the cell types that drive neuroblastoma development in TH-MYCN transgenic mice, an animal model of the human disease. Neuroblastoma development in these mice begins with hyperplastic lesions in early postnatal sympathetic ganglia. We show that both hyperplasia and primary tumors are composed predominantly of highly proliferative Phox2B+ neuronal progenitors. MYCN induces the expansion of these progenitors by both promoting their proliferation and preventing their differentiation. We further identify a minor population of undifferentiated nestin+ cells in both hyperplastic lesions and primary tumors that may serve as precursors of Phox2B+ neuronal progenitors. These findings establish the identity of neuroblasts that characterize the tumor phenotype and suggest a cellular pathway by which MYCN can promote neuroblastoma development. PMID:19608868

We aimed to analyze clinical features and treatment outcomes of otitis media caused by antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), i.e. otitis media with AAV (OMAAV). This survey was performed between December 2013 and February 2014. The study began with a preliminary survey to 123 otolaryngology institutions in Japan to inquire about their experiences with OMAAV patients during the past 10 years, and was followed by a questionnaire survey to investigate clinical and laboratory findings. OMAAV was defined using the criteria described in the text. Two hundred and thirty-five patients classified as OMAAV were enrolled in this study. They were characterized as follows: (1) disease onset with initial signs/symptoms due to intractable otitis media with effusion or granulation, which did not respond to ordinary treatments such as antibiotics and insertion of tympanic ventilation tubes, followed by progressive hearing loss; (2) predominantly female (73%) and older (median age: 68 years); (3) predominantly myeloperoxidase (MPO)-ANCA-positive (60%), followed by proteinase 3 (PR3)-ANCA-positive (19%) and both ANCAs-negative (16%); (4) frequently observed accompanying facial palsy (36%) and hypertrophic pachymeningitis (28%); and (5) disease often involving lung (35%) and kidney (26%) lesions. Four factors associated with OMAAV were found to be related to an unfavorable clinical course threatening the patient's hearing and/or lives, namely facial palsy, hypertrophic pachymeningitis, both ANCAs-negative phenotype, and disease relapse. The occurrence of hypertrophic pachymeningitis was associated with facial palsy (p < 0.05), both ANCAs-negative phenotype (p < 0.001), and headache (p < 0.001). The administration of corticosteroid together with an immunosuppressant was an independent predicting factor for lack of disease relapse (odds ratio [OR] = 1.90, p = 0.03) and an improvement in hearing loss (OR =2.58, p = 0.0002). Since OMAAV has novel clinical features, the disease may be categorized as a subentity for the classification of AAV.

Despite seemingly functional coagulation, hemorrhagic lesion progression is a common and devastating condition following traumatic brain injury (TBI), stressing the need for new diagnostic techniques. Multiple electrode aggregometry (MEA) measures platelet function and could aid in coagulopathy assessment following TBI. The aims of this study were to evaluate MEA temporal dynamics, influence of concomitant therapy, and its capabilities to predict lesion progression and clinical outcome in a TBI cohort. Adult TBI patients in a neurointensive care unit that underwent MEA sampling were retrospectively included. MEA was sampled if the patient was treated with antiplatelet therapy, bled heavily during surgery, or had abnormal baseline coagulation values. We assessed platelet activation pathways involving the arachidonic acid receptor (ASPI), P2Y 12 receptor, and thrombin receptor (TRAP). ASPI was the primary focus of analysis. If several samples were obtained, they were included. Retrospective data were extracted from hospital charts. Outcome variables were radiologic hemorrhagic progression and Glasgow Outcome Scale assessed prospectively at 12 months posttrauma. MEA levels were compared between patients on antiplatelet therapy. Linear mixed effect models and uni-/multivariable regression models were used to study longitudinal dynamics, hemorrhagic progression and outcome, respectively. In total, 178 patients were included (48% unfavorable outcome). ASPI levels increased from initially low values in a time-dependent fashion ( p  < 0.001). Patients on cyclooxygenase inhibitors demonstrated low ASPI levels ( p  < 0.001), while platelet transfusion increased them ( p  < 0.001). The first ASPI ( p  = 0.039) and TRAP ( p  = 0.009) were significant predictors of outcome, but not lesion progression, in univariate analyses. In multivariable analysis, MEA values were not independently correlated with outcome. A general longitudinal trend of MEA is identified in this TBI cohort, even in patients without known antiplatelet therapies. Values appear also affected by platelet inhibitory treatment and by platelet transfusions. While significant in univariate models to predict outcome, MEA values did not independently correlate to outcome or lesion progression in multivariable analyses. Further prospective studies to monitor coagulation in TBI patients are warranted, in particular the interpretation of pathological MEA values in patients without antiplatelet therapies.

Platelets play a key role in the progression of acute coronary syndromes (ACS). Clinical depression alone is also associated with enhanced platelet activation. The purpose of this study was to compare concentrations of established biomarkers of enhanced platelet/endothelial activation in clinically depressed versus non-depressed patients enrolled in recent clinical trials for ACS. Two hundred and eighty-one baseline plasma samples from patients with acute myocardial infarction (ASSENT-2; n = 41), with ACS (PRONTO; n = 126) and with clinical depression plus previous acute coronary syndrome within 6 months (SADHART; n = 64), and from normal healthy controls (n = 50) were analyzed. Blood was drawn before applying any therapeutic strategies including interventions, thrombolytics, infusions, and selective serotonin re-uptake inhibitors. Platelet factor 4, beta-thromboglobulin, platelet/endothelial cell adhesion molecule-1, P-selectin, thromboxane, prostacyclin, vascular cell adhesion molecule-1, and E-selectin were measured by enzyme-linked immunosorbent assay by a single core laboratory. Patients with ACS exhibited a higher degree of platelet activation than controls independently of the presence of depression. Plasma levels of P-selectin, thromboxane, prostacyclin, and vascular cell adhesion molecule-1 were the highest in the acute myocardial infarction group when compared with ACS despite the presence or absence of clinical depression. Surprisingly, patients with ACS and depression exhibited the highest levels of platelet factor 4, beta-thromboglobulin, and platelet/endothelial cell adhesion molecule-1 when compared with myocardial infarction or angina patients without clinical depression. E-selectin plasma level was constantly elevated compared with controls but did not differ among the groups dependent on the incidence of depression. The depressed plus ACS group had higher plasma levels of all biomarkers compared with the non-depressed patients. Retrospective analysis of the data from several clinical trials reveals that clinical depression is associated with enhanced activation of platelet/endothelial biomarkers even above the level expected in ACS. These findings may contribute to the unfavorable outcome associated with clinical depression in patients with ACS.

Dental implants positioned in severely atrophied anterior maxillae require esthetic or functional compromises. This case report describes the rehabilitation of a severely atrophied alveolar ridge with a three-dimensional (3D) computer-aided design/computer-aided manufacture (CAD/CAM) surgical guide. A 50-year-old woman had a severely atrophied anterior maxilla with unfavorably positioned dental implants. Functional and esthetic prosthodontic restoration was difficult to achieve. An anterior segmental osteotomy was planned to reposition the dental implants. A 3D surgical guide was designed for precise relocation of the segment. The surgical guide firmly grasped the impression copings of the dental implants, minimizing surgical errors. Three-dimensional gingival simulation was used preoperatively to estimate the appropriate position of the gingiva. Rigid fixation to the surrounding bone allowed immobilization of the implant-bone segment. Satisfactory esthetic and functional outcomes were attained 6 months after surgery. Finally, a severely atrophied alveolar ridge with unfavorably positioned dental implants was recovered with minimal esthetic and functional deterioration using gingival simulation and a 3D CAD/CAM surgical guide.

Acute myeloid leukemia (AML) with mutated NPM1 is a newly recognized separate entity in the revised 2016 World Health Organization classification and is associated with a favorable prognosis. Although previous studies have evaluated NPM1 in a binary fashion, little is known about the significance of its mutant allele burden at diagnosis, nor has the effect of comutations (other than FLT3 ) been extensively evaluated. We retrospectively used targeted sequencing data from 109 patients with de novo AML with mutated NPM1 to evaluate the potential significance of NPM1 variant allele frequency (VAF), comutations, and clinical parameters with regard to patient outcomes. We observed that high NPM1 VAF (uppermost quartile) correlated with shortened overall survival (median, 12.1 months vs not reached; P < .0001) as well as event-free survival (median, 7.5 vs 65.44 months; P < .0001) compared with the other NPM1 -mutated cases. In both univariate and multivariable analyses, high NPM1 VAF had a particularly adverse prognostic effect in the subset of patients treated with stem-cell transplantation in first remission ( P = .0004) and in patients with mutated DNMT3A ( P < .0001). Our findings indicate that the prognostic effect of NPM1 mutation in de novo AML may be influenced by the relative abundance of the mutated allele. © 2018 by The American Society of Hematology.

Stephen L. Gans overseas lecture. Mass screening for neuroblastoma in Japan: lessons learned and future directions.

Since 1985, a nationwide mass screening program (MS) for neuroblastoma has been conducted for 6-month-old infants throughout Japan, resulting in the detection of more than 1,900 cases of neuroblastoma. The outcome of these patients has been excellent: more than 97% of them are alive. Yet, several reports suggest that the number of advanced-stage neuroblastoma patients over 1 year of age has not changed substantially. The current report focuses on the 15-year experience with MS of the Kyushu Pediatric Oncology Study Group. The clinical and biological features of neuroblastoms detected (n = 320) and not detected by MS (n = 245) were compared. Regional and national statistics for neuroblastoma before and after 1985 were analyzed using standard epidemiologic measures for the occurrence of disease. The majority of the MS-positive cases were biologically favorable and had an excellent outcome. In contrast, the majority of non-MS patients in whom neuroblastoma later developed had advanced-stage, unfavorable-prognosis tumors. The overall mortality rate of neuroblastoma in the Kyushu area was not improved by MS. The optimal time for screening is the point at which neuroblastomas regressing spontaneously can no longer be detected, but more aggressive disease can be found. A birth cohort study could determine the optimal timing for a second screening. Identification of other new prognostic factors may be required. Copyright 2002, Elsevier Science (USA).

Since the birth of the first IVF-conceived child in 1978, the use of assisted reproductive technologies (ART) has grown dramatically, contributing to the successful birth of 5 million individuals worldwide. However, there are several reported associations of ART with pregnancy complications, such as low birthweight (LBW), preterm birth, birth defects, epigenetic disorders, cancer and poor metabolic health. Whether this is attributed to ART procedures or to the subset of the population seeking ART remains a controversy, but the most relevant question today concerns the potential long-term implications of assisted conception. Recent evidence has emerged suggesting that ART-conceived children have distinct metabolic profiles that may predispose to cardiovascular pathologies in adulthood. Because the eldest IVF individuals are still too young to exhibit components of chronic middle-aged syndromes, the use of animal models has become particularly useful in describing the effects of unusual or stressful preimplantation experiences on adult fitness. Elucidating the molecular mechanisms by which embryos integrate environmental signals into development and metabolic gene expression programs will be essential for optimizing ART procedures such as in vitro culture conditions, embryo selection and transfer. In the future, additional animal studies to identify mechanisms underlying unfavorable ART outcomes, as well as more epidemiological reviews to monitor the long-term health of ART children are required, given that ART procedures have become routine medical practice.

Acute myeloid leukemia (AML) is a heterogeneous disease, and optimal treatment varies according to cytogenetic risk factors and molecular markers. Several studies have demonstrated the prognostic importance of microRNAs (miRNAs) in AML. Here we report a potential association between miRNA expression and clinical outcome in 238 intermediate-risk cytogenetic AML (IR-AML) patients from 16 institutions in the CETLAM cooperative group. We first profiled 670 miRNAs in a subset of 85 IR-AML patients from a single institution and identified 10 outcome-related miRNAs. We then validated these 10 miRNAs by individual assays in the total cohort and confirmed the prognostic impact of 4 miRNAs. High levels of miR-196b and miR-644 were independently associated with shorter overall survival, and low levels of miR-135a and miR-409-3p with a higher risk of relapse. Interestingly, miR-135a and miR-409-3p maintained their independent prognostic value within the unfavorable molecular subcategory (wild-type NPM1 and CEBPA and/or FLT3-ITD), and miR-644 retained its value within the favorable molecular subcategory. miR-409-3p, miR-135a, miR-196b and mir-644 arose as prognostic markers for IR-AML, both overall and within specific molecular subgroups.

Surface roughness has been reported to both increase as well as decrease colloid retention. In order to better understand the boundaries within which roughness operates, attachment of a range of colloid sizes to glass with three levels of roughness was examined under both favorable (energy barrier absent) and unfavorable (energy barrier present) conditions in an impinging jet system. Smooth glass was found to provide the upper and lower bounds for attachment under favorable and unfavorable conditions, respectively. Surface roughness decreased, or even eliminated, the gap between favorable and unfavorable attachment and did so by two mechanisms: (1) under favorable conditions attachment decreased via increased hydrodynamic slip length and reduced attraction and (2) under unfavorable conditions attachment increased via reduced colloid-collector repulsion (reduced radius of curvature) and increased attraction (multiple points of contact, and possibly increased surface charge heterogeneity). Absence of a gap where these forces most strongly operate for smaller (<200 nm) and larger (>2 μm) colloids was observed and discussed. These observations elucidate the role of roughness in colloid attachment under both favorable and unfavorable conditions.

We compared histomorphological features and molecular expression profiles of adrenocortical adenomas (ACAd) and carcinomas (ACCa). A critical histopathological review (mean, 11 slides per patient) was conducted of 37 ACAd and 67 ACCa. Paraffin-embedded tissue cores of ACAd (n = 33) and ACCa (n = 38) were arrayed in triplicate on tissue microarrays. Expression profiles of p53, mdm-2, p21, Bcl-2, cyclin D1, p27, and Ki-67 were investigated by immunohistochemistry and correlated with histopathology and patient outcome using standard statistical methodology. Median follow-up period was 5 years. Tumor necrosis, atypical mitoses, and >1 mitosis per 50 high-power fields were factors that were highly specific for ACCa (P <.001). Number (0 to 4) of unfavorable markers [Ki-67 (+), p21 (+), p27 (+), mdm-2(-)] expressed was significantly associated with mitotic activity and morphologic index (i.e., number of adverse morphologic features) and highly predictive of malignancy (P <.001). Ki-67 overexpression occurred in 0 ACAd and 36% ACCa (P <.001) and was significantly associated with mitotic rate and unfavorable morphologic index (P <.001). Tumor necrosis, atypical mitoses, >5 mitoses per 50 high-power fields, sinusoidal invasion, histologic index of >5, and presence of more than two unfavorable molecular markers were associated significantly with metastasis in ACCa. Well-established histopathologic criteria and Ki-67 can specifically distinguish ACCAd from ACCa. Tumor cell proliferation (Ki-67) correlates with mitotic activity and morphologic index. Tumor morphology is a better predictor of metastatic risk in ACCa than current immunohistochemistry-detected cell cycle regulatory and proliferation-associated proteins.

Objective: We hypothesize that the major consciousness deficit observed in coma is due to the breakdown of long-range neuronal communication supported by precuneus and posterior cingulate cortex (PCC), and that prognosis depends on a specific connectivity pattern in these networks. Methods: We compared 27 prospectively recruited comatose patients who had severe brain injury (Glasgow Coma Scale score <8; 14 traumatic and 13 anoxic cases) with 14 age-matched healthy participants. Standardized clinical assessment and fMRI were performed on average 4 ± 2 days after withdrawal of sedation. Analysis of resting-state fMRI connectivity involved a hypothesis-driven, region of interest–based strategy. We assessed patient outcome after 3 months using the Coma Recovery Scale–Revised (CRS-R). Results: Patients who were comatose showed a significant disruption of functional connectivity of brain areas spontaneously synchronized with PCC, globally notwithstanding etiology. The functional connectivity strength between PCC and medial prefrontal cortex (mPFC) was significantly different between comatose patients who went on to recover and those who eventually scored an unfavorable outcome 3 months after brain injury (Kruskal-Wallis test, p < 0.001; linear regression between CRS-R and PCC-mPFC activity coupling at rest, Spearman ρ = 0.93, p < 0.003). Conclusion: In both etiology groups (traumatic and anoxic), changes in the connectivity of PCC-centered, spontaneously synchronized, large-scale networks account for the loss of external and internal self-centered awareness observed during coma. Sparing of functional connectivity between PCC and mPFC may predict patient outcome, and further studies are needed to substantiate this potential prognosis biomarker. PMID:26561296

Hemispheric location might influence outcome after intracerebral hemorrhage (ICH). INTERACT suggested higher short-term mortality in right hemispheric ICH, yet statistical imbalances were not addressed. This study aimed at determining the differences in long-term functional outcome in patients with right- vs. left-sided ICH with a priori-defined sub-analysis of lobar vs. deep bleedings. Data from a prospective hospital registry were analyzed including patients with ICH admitted between January 2006 and August 2014. Data were retrieved from institutional databases. Outcome was assessed using the modified Rankin Scale (mRS) score. Outcome measures (long-term mortality and functional outcome at 12 months) were correlated with ICH location and hemisphere, and the imbalances of baseline characteristics were addressed by propensity score matching. A total of 831 patients with supratentorial ICH (429 left and 402 right) were analyzed. Regarding clinical baseline characteristics in the unadjusted overall cohort, there were differences in disfavor of right-sided ICH (antiplatelets: 25.2% in left ICH vs. 34.3% in right ICH; p < 0.01; previous ischemic stroke: 14.7% in left ICH vs. 19.7% in right ICH; p = 0.057; and presence/extent of intraventricular hemorrhage: 45.0% in left ICH vs. 53.0% in right ICH; p = 0.021; Graeb-score: 0 [0-4] in left ICH vs. 1 [0-5] in right ICH; p = 0.017). While there were no differences in mortality and in the proportion of patients with favorable vs. unfavorable outcome (mRS 0-3: 142/375 [37.9%] in left ICH vs. 117/362 [32.3%] in right ICH; p = 0.115), patients with left-sided ICH showed excellent outcome more frequently (mRS 0-1: 64/375 [17.1%] in left ICH vs. 43/362 [11.9%] in right ICH; p = 0.046) in the unadjusted analysis. After adjusting for confounding variables, a well-balanced group of patients (n = 360/hemisphere) was compared showing no differences in long-term functional outcome (mRS 0-3: 36.4% in left ICH vs. 33.9% in right ICH; p = 0.51). Sub-analyses of patients with deep vs. lobar ICH revealed also no differences in outcome measures (mRS 0-3: 53/151 [35.1%] in left deep ICH vs. 53/165 [32.1%] in right deep ICH; p = 0.58). Previously described differences in clinical end points among patients with left- vs. right-hemispheric ICH may be driven by different baseline characteristics rather than by functional deficits emerging from different hemispheric functions affected. After statistical corrections for confounding variables, there was no impact of hemispheric location on functional outcome after ICH. © 2017 S. Karger AG, Basel.

Sex and Gender Differences in Risk, Pathophysiology and Complications of Type 2 Diabetes Mellitus.

The steep rise of type 2 diabetes mellitus (T2DM) and associated complications go along with mounting evidence of clinically important sex and gender differences. T2DM is more frequently diagnosed at lower age and body mass index in men; however, the most prominent risk factor, which is obesity, is more common in women. Generally, large sex-ratio differences across countries are observed. Diversities in biology, culture, lifestyle, environment, and socioeconomic status impact differences between males and females in predisposition, development, and clinical presentation. Genetic effects and epigenetic mechanisms, nutritional factors and sedentary lifestyle affect risk and complications differently in both sexes. Furthermore, sex hormones have a great impact on energy metabolism, body composition, vascular function, and inflammatory responses. Thus, endocrine imbalances relate to unfavorable cardiometabolic traits, observable in women with androgen excess or men with hypogonadism. Both biological and psychosocial factors are responsible for sex and gender differences in diabetes risk and outcome. Overall, psychosocial stress appears to have greater impact on women rather than on men. In addition, women have greater increases of cardiovascular risk, myocardial infarction, and stroke mortality than men, compared with nondiabetic subjects. However, when dialysis therapy is initiated, mortality is comparable in both males and females. Diabetes appears to attenuate the protective effect of the female sex in the development of cardiac diseases and nephropathy. Endocrine and behavioral factors are involved in gender inequalities and affect the outcome. More research regarding sex-dimorphic pathophysiological mechanisms of T2DM and its complications could contribute to more personalized diabetes care in the future and would thus promote more awareness in terms of sex- and gender-specific risk factors.

Rhabdomyosarcoma (RMS) is divided into two major histological subtypes: alveolar (ARMS) and embryonal (ERMS), with most ARMS expressing one of two oncogenic genes fusing PAX3 or PAX7 with FOXO1 (P3F and P7F, respectively). The Children's Oncology Group (COG) carried out a multi-institutional clinical trial to evaluate the prognostic value of PAX-FOXO1 fusion status. Study participants were treated on COG protocol D9803 for intermediate risk ARMS or ERMS using multi-agent chemotherapy, radiotherapy, and surgery. Central diagnostic pathology review and molecular testing for fusion genes were carried out on prospectively collected specimens. Event-free (EFS) and overall survival (OS) at 5 years were correlated with histological subtype and PAX-FOXO1 status. Of 616 eligible D9803 enrollees, 434 cases had adequate clinical, molecular, and pathology data for definitive classification as ERMS, ARMS P3F+ or P7F+, or ARMSn (without detectable fusion). EFS was worse for those with ARMS P3F+ (54%) and P7F+ (65%) than those with ERMS (77%; P < 0.001). EFS for ARMSn and ERMS were not statistically different (90% vs. 77%, P = 0.15). ARMS P3F+ had poorer OS (64%) than ARMS P7F+ (87%), ARMSn (89%), and ERMS (82%; P = 0.006). ARMSn has an outcome similar to ERMS and superior EFS compared to ARMS with either P3F or P7F, when given therapy designed for children with intermediate risk RMS. This prospective analysis supports incorporation of PAX-FOXO1 fusion status into risk stratification and treatment allocation. Copyright © 2013 Wiley Periodicals, Inc.

To evaluate the use of a transcervical Foley catheter plus oxytocin infusion compared with oxytocin infusion alone for labor induction and cervical ripening in women 34 weeks of gestation or greater with prelabor rupture of membranes. This is a randomized, multicenter trial of women with a live, singleton gestation at 34 weeks of gestation or greater with prelabor rupture of membranes, an unfavorable cervical examination (less than 2 cm or 80% effaced), and no contraindication to labor. Participants were randomly allocated to a transcervical Foley catheter inflated to 30 cc with concurrent oxytocin infusion or oxytocin infusion alone. Oxytocin administration was standardized across sites. The primary study outcome was interval from induction to delivery. To detect a 2.5-hour difference in the interval from induction to delivery, we required outcome data on 194 women, assuming 80% power and a two-tailed α of 5%. Analysis was by intent to treat. We enrolled 201 women: 93 were allocated to Foley and 108 to oxytocin. Demographics were similar between the groups. Time to delivery was not significantly different between groups: in the Foley group, it was 13.9 hours (±6.9 SD) compared with 14.4 hours (±7.9 SD) in the oxytocin group (P=.69). There were more cases of clinical chorioamnionitis (8% compared with 0%, P<.01) in the Foley group compared with the oxytocin group. There were no differences for other infectious morbidities or any other variable studied. In patients with prelabor rupture of membranes, the use of a transcervical Foley catheter in addition to oxytocin does not shorten the time to delivery compared with oxytocin alone, but may increase the incidence of intraamniotic infection.

Solid organ transplant (SOT) recipients are at risk of infections of the central nervous system. However, the incidence and clinical course of bacterial meningitis in SOT recipients are unclear. We studied occurrence, disease course, and prognosis of bacterial meningitis in SOT recipients in the Netherlands. All patients with a medical history of solid organ transplantation were selected from our nationwide prospective cohort study on community-acquired bacterial meningitis in patients >16 years old, performed from March 1, 2006 to October 31, 2014. Data on patient history, symptoms and signs on admission, treatment, and outcome were collected prospectively. For transplant recipients, additional information was collected retrospectively. We identified 6 SOT recipients, all receiving renal transplants. The annual incidence of bacterial meningitis was 7-fold higher (95% confidence interval [CI] 2.94-17.02, P < 0.001) for renal transplant recipients as compared with the general population (9.56 [95% CI 3.98-22.96] vs. 1.35 [95% CI 1.28-1.43] per 100,000 patients per year). One of the 6 patients (17%) presented with the classic presentation of bacterial meningitis (fever, neck stiffness, and change in mental status). Seizures were common, occurring in 33% of patients. Streptococcus pneumoniae and Listeria monocytogenes were identified in 2 patients each, and Escherichia coli and Pseudomonas aeruginosa were both identified once. Four of 6 patients (67%) had an unfavorable functional outcome. Bacterial meningitis is a rare but devastating complication of solid organ transplantation. SOT recipients are at high risk for developing meningitis, and recognition of this condition may be difficult, owing to atypical clinical manifestation. © 2016 The Authors.

Background We aimed to determine whether serum soluble CD30 (sCD30) could identify recipients at high risk for unfavorable early and late kidney transplant outcomes. Methods Serum sCD30 was measured on the day of kidney transplantation and on the 4th day posttransplant. We assessed the value of these measurements in predicting delayed graft function, slow graft function (SGF), acute rejection (AR), pyelonephritis, decline of allograft function after 6 months, and graft and patient survival during 5 years of follow-up in 45 recipients. Results We found the association between low pretransplant serum levels of sCD30 and SGF. The absence of significant decrease of sCD30 on the 4th day posttransplant was characteristic for SGF, early AR (the 8th day–6 months), late AR (>6 months), and early pyelonephritis (the 8th day–2 months). Lower pretransplant and posttransplant sCD30 predicted worse allograft function at 6 months and 2 years, respectively. Higher pretransplant sCD30 was associated with higher frequency of early AR, and worse patients' survival, but only in the recipients of deceased-donor graft. Pretransplant sCD30 also allowed to differentiate patients with early pyelonephritis and early AR. Conclusions Peritransplant sCD30 is useful in identifying patients at risk for unfavorable early and late transplant outcomes. PMID:28694560

To justify or excuse?: A meta-analytic review of the effects of explanations.

The authors used R. Folger and R. Cropanzano's (1998, 2001) fairness theory to derive predictions about the effects of explanation provision and explanation adequacy on justice judgments and cooperation, retaliation, and withdrawal responses. The authors also used the theory to identify potential moderators of those effects, including the type of explanation (justification vs. excuse), outcome favorability, and study context. The authors' predictions were tested by using meta-analyses of 54 independent samples. The results showed strong effects of explanations on both the justice and response variables. Moreover, explanations were more beneficial when they took the form of excuses rather than justifications, when they were given after unfavorable outcomes, and when they were given in contexts with instrumental, relational, and moral implications.

Although surgical gastrostomy is not a technically troublesome surgery, the procedure may be accompanied by unfavorable outcomes. Most complications occur early in the post-operative period and include feeding tube dislodgment, stomal infection, peritonitis, and pneumonia. The authors report the case of an 83-year-old man who underwent a surgical gastrostomy because of a swallowing disorder after an ischemic stroke. Nine months after the procedure, the feeding tube dislodged and a new tube was inserted with a certain delay and with some difficulty, causing a false path and consequently an intrabdominal abscess after diet infusion. The outcome was fatal. The authors call attention for meticulous care with the insertion of feeding tubes and advise the performance of imaging control to assure its precise positioning.

To date, many prognostic models have been proposed to predict the outcome of patients with traumatic brain injuries. External validation of these models in different populations is of great importance for their generalization. The present study was designed, aiming to determine the value of CRASH prognostic model in prediction of 14-day mortality (14-DM) and 6-month unfavorable outcome (6-MUO) of patients with traumatic brain injury. In the present prospective diagnostic test study, calibration and discrimination of CRASH model were evaluated in head trauma patients referred to the emergency department. Variables required for calculating CRASH expected risks (ER), and observed 14-DM and 6-MUO were gathered. Then ER of 14-DM and 6-MUO were calculated. The patients were followed for 6 months and their 14-DM and 6-MUO were recorded. Finally, the correlation of CRASH ER and the observed outcome of the patients was evaluated. The data were analyzed using STATA version 11.0. In this study, 323 patients with the mean age of 34.0 ± 19.4 years were evaluated (87.3% male). Calibration of the basic and CT models in prediction of 14-day and 6-month outcome were in the desirable range (P < 0.05). Area under the curve in the basic model for prediction of 14-DM and 6-MUO were 0.92 (95% CI: 0.89-0.96) and 0.92 (95% CI: 0.90-0.95), respectively. In addition, area under the curve in the CT model for prediction of 14-DM and 6-MUO were 0.93 (95% CI: 0.91-0.97) and 0.93 (95% CI: 0.91-0.96), respectively. There was no significant difference between the discriminations of the two models in prediction of 14-DM (p = 0.11) and 6-MUO (p = 0.1). The results of the present study showed that CRASH prediction model has proper discrimination and calibration in predicting 14-DM and 6-MUO of head trauma patients. Since there was no difference between the values of the basic and CT models, using the basic model is recommended to simplify the risk calculations.

Chemoradiotherapy is the treatment mostly used as organ preservation (OP) strategy worldwide in advanced laryngo-hypopharyngeal cancer. Due to the not homogeneous results of the literature data regarding the pre-treatment assessment and treatment schedule in this setting of patients, the Italian societies of radiation oncology and medical oncology surveyed (by an online survey) their memberships regarding the Italian attitude on larynx preservation in clinical practice. The survey outline addressed different items such as: demographics (11 items), pre-treatment evaluation (12 items), treatment schedules (10 items) and outcomes (3 items). The survey was filled in by 116 clinical oncologists (64 % radiation and 36 % medical oncologists). Results highlighted that pretreatment evaluation was not homogeneous among the respondents. The treatment of choice for the OP program resulted the concurrent chemoradiotherapy (66 %). Induction chemotherapy was proposed mostly in case of aggressive tumors such as advanced stage (T4 or N3) and/or unfavorable primary sites (hypopharynx). Moreover, after induction chemotherapy, for responders patients most participants (46 %) proposed concurrent chemoradiotherapy, while 18 and 19 % proposed radiotherapy alone or radiotherapy and cetuximab, respectively. For patients with stable disease after induction chemotherapy, the respondents declared to suggest surgery, radiotherapy and cetuximab or radiotherapy alone in 38, 32 and 15 % of cases, respectively. Results of the present survey highlighted the variability of therapeutic approaches offered in clinical practice for patients candidate to a larynx OP program. Analysis of abovementioned results may give the chance to modify some clinical attitudes and create the background for future clinical investigation in this field.

There have been no major advances in tuberculosis (TB) drug development since the first East African/British Medical Research Council short course chemotherapy trial 35 years ago. Since then, the landscape for conducting TB clinical trials has profoundly changed with the emergence of HIV infection, the spread of resistant TB bacilli strains, recent advances in mycobacteriological capacity, and drug discovery. As a consequence questions have arisen on the most appropriate approach to design and conduct current TB trials. To highlight key issues discussed: Is a superiority, equivalence, or non-inferiority design most appropriate? What should be the primary efficacy outcome? How to consider re-infections in the definition of the outcome? What is the optimal length of patient follow-up? Is blinding appropriate when treatment duration in test arm is shorter? What are the appropriate assumptions for sample size calculation? Various drugs are currently in the development pipeline. We are presenting in this paper the design of the most recently completed phase III TB trial, the OFLOTUB project, which is the pivotal trial of a registration portfolio for a gatifloxacin-containing TB regimen. It is a randomized, open-label, multicenter, controlled trial aiming to evaluate the efficacy and safety of a gatifloxacin-containing 4-month regimen (trial registration: ClinicalTrial.gov database: NCT00216385). In the light of the recent scientific and regulatory discussions, we discuss some of the design issues in TB clinical trials and more specifically the reasons that guided our choices, in order to best answer the trial objectives, while at the same time satisfying regulatory authority requirements. When shortening TB treatment, we are advocating for a non-inferiority, non-blinded design, with a composite unfavorable endpoint assessed 12 months post treatment completion, and added trial procedures specifically aiming to: (1) minimize endpoint unavailability; and (2) distinguish between relapse and re-infection.

Computed tomography (CT) is useful for the diagnosis of local complications in children with acute pancreatitis but its role as a prognostic tool remains controversial. To establish the correlation between the CT Severity Index and the Revised Atlanta Classification regarding unfavorable outcomes such as severe acute pancreatitis and need for Pediatric Special Care Unit attention in children with acute pancreatitis. We conducted a retrospective and concordance cohort study in which we obtained abdominal CT scans from 30 patients ages 0 to 18 years with acute pancreatitis. Two pediatric radiologists interpreted the results using the CT Severity Index and the Revised Atlanta Classification. The kappa coefficient was determined for each scale. The association among severe acute pancreatitis, need for admission to the Pediatric Special Care Unit and CT systems were established using chi-square or Mann-Whitney U tests. The best CT Severity Index value to predict the need for admission to the Pediatric Special Care Unit was estimated through a receiver operating characteristic (ROC) curve. Mean CT Severity Index was 5.1±2.8 (mean ± standard deviation on a scale of 0 to 10) for the severe acute pancreatitis group vs. 3.8±2.7 for the mild acute pancreatitis group (P=0.230). The CT Severity Index for the children who were not hospitalized at the Pediatric Special Care Unit was 2.2±2.2 vs. 5.6±2.4 for the group hospitalized at the Pediatric Special Care Unit (P=0.001). Only parenchymal necrosis >30% was associated with severe acute pancreatitis (P=0.021). A CT Severity Index ≥3 has a sensitivity of 89% and specificity of 72% to predict need for admission to the Pediatric Special Care Unit. None of the Revised Atlanta Classification categories was associated with severe acute pancreatitis or admission to the Pediatric Special Care Unit. A CT Severity Index ≥3 in children with acute pancreatitis who require CT assessment based on clinical criteria is associated with the need for admission to the Pediatric Special Care Unit. We found that pancreatic necrosis greater than 30% is the only tomographic parameter related to severe acute pancreatitis. New studies with a greater sample size are necessary to confirm this result.

OBJECTIVE In severe traumatic brain injury (TBI), the effects of decompressive craniectomy (DC) on brain tissue oxygen pressure (PbtO 2 ) and outcome are unclear. The authors aimed to investigate whether changes in PbtO 2 after DC could be used as an independent prognostic factor. METHODS The authors conducted a retrospective, observational study at 2 university hospital ICUs. The study included 42 patients who were admitted with isolated moderate or severe TBI and underwent intracranial pressure (ICP) and PbtO 2 monitoring before and after DC. The indication for DC was an ICP higher than 25 mm Hg refractory to first-tier medical treatment. Patients who underwent primary DC for mass lesion evacuation were excluded. However, patients were included who had undergone previous surgery as long as it was not a craniectomy. ICP/PbtO 2 monitoring probes were located in an apparently normal area of the most damaged hemisphere based on cranial CT scanning findings. PbtO 2 values were routinely recorded hourly before and after DC, but for comparisons the authors used the first PbtO 2 value on ICU admission and the number of hours with PbtO 2 < 15 mm Hg before DC, as well as the mean PbtO 2 every 6 hours during 24 hours pre- and post-DC. The end point of the study was the 6-month Glasgow Outcome Scale; a score of 4 or 5 was considered a favorable outcome, whereas a score of 1-3 was considered an unfavorable outcome. RESULTS Of the 42 patients included, 26 underwent unilateral DC and 16 bilateral DC. The median Glasgow Coma Scale score at the scene of the accident or at the initial hospital before the patient was transferred to one of the 2 ICUs was 7 (interquartile range [IQR] 4-14). The median time from admission to DC was 49 hours (IQR 7-301 hours). Before DC, the median ICP and PbtO 2 at 6 hours were 35 mm Hg (IQR 28-51 mm Hg) and 11.4 mm Hg (IQR 3-26 mm Hg), respectively. In patients with favorable outcome, PbtO 2 at ICU admission was higher and the percentage of time that pre-DC PbtO 2 was < 15 mm Hg was lower (19 ± 4.5 mm Hg and 18.25% ± 21.9%, respectively; n = 28) than in those with unfavorable outcome (12.8 ± 5.2 mm Hg [p < 0.001] and 59.58% ± 38.8% [p < 0.001], respectively; n = 14). There were no significant differences in outcomes according to the mean PbtO 2 values only during the last 12 hours before DC, the hours of refractory intracranial hypertension, the timing of DC from admission, or the presence/absence of previous surgery. In contrast, there were significant differences in PbtO 2 values during the 12- to 24-hour period before DC. In most patients, PbtO 2 increased during the 24 hours after DC but these changes were more pronounced in patients with favorable outcome than in those with unfavorable outcome (28.6 ± 8.5 mm Hg vs 17.2 ± 5.9 mm Hg, p < 0.0001; respectively). The areas under the curve for the mean PbtO 2 values at 12 and 24 hours after DC were 0.878 (95% CI 0.75-1, p < 0.0001) and 0.865 (95% CI 0.73-1, p < 0.0001), respectively. CONCLUSIONS The authors' findings suggest that changes in PbtO 2 before and after DC, measured with probes in healthy-appearing areas of the most damaged hemisphere, have independent prognostic value for the 6-month outcome in TBI patients.

Using decompressive craniectomy as part of the treatment regimen for severe traumatic brain injury (STBI) has become more common at our Level I trauma center. This study was designed to examine this practice with particular attention to long-term functional outcome. A retrospective review of prospectively collected data was performed for patients with STBI admitted from January 1, 2003 to December 31, 2005. Our institution manages patients using the Brain Trauma Foundation Guidelines. Data collected from patients undergoing decompressive craniectomy included: age, Injury Severity Score, admission and follow-up Glasgow Coma Score, timing of, and indication for decompressive craniectomy, and procedure-related complications. The Extended Glasgow Outcome Scale (GOSE) was performed by a experienced trauma clinical research coordinator using a structured phone interview to assess long-term outcome in the survivors. Student's t test and chi2 were used to examine differences between groups. Forty STBI patients were treated with decompressive craniectomy; 24 were performed primarily in conjunction with urgent evacuation of extra-axial hemorrhage and 16 were performed primarily in response to increased intracranial pressure with 4 of these after an initial craniotomy. Decompressive craniectomy was very effective at lowering intracranial pressure in these 16 patients (35.0 mm Hg +/- 13.5 mm Hg to 14.6 mm Hg +/- 8.7 mm Hg, p = 0.005). Twenty-two decompressive craniectomy patients did not survive to hospital discharge, whereas admission Glasgow Coma Score and admission pupil size and reactivity correlated with outcome, age, and Injury Severity Score did not. At a mean of 11 months (range, 3-26 months) after decompressive craniectomy, 6 survivors had a poor functional outcome (GOSE 1-4), whereas 12 survivors had a good outcome (GOSE 5-8). Therefore, 70% of these patients had an unfavorable outcome (death or severe disability), and 30% had a favorable long-term functional outcome. Fifteen of 18 survivors went on to cranioplasty, whereas 4 of 18 had cerebrospinal infection. The majority of survivors after decompressive craniectomy have a good functional outcome as analyzed by GOSE. Overall, 30% of patients with STBI who underwent decompressive craniectomy had a favorable long-term outcome. Improving patient selection and optimizing timing of this procedure may further improve outcome in these very severely brain injured patients.

OBJECTIVE The role of venous sinus stenting (VSS) for idiopathic intracranial hypertension (IIH) is not well understood. The aim of this systematic review is to attempt to identify subsets of patients with IIH who will benefit from VSS based on the pressure gradients of their venous sinus stenosis. METHODS MEDLINE/PubMed was searched for studies reporting venous pressure gradients across the stenotic segment of the venous sinus, pre- and post-stent pressure gradients, and clinical outcomes after VSS. Findings are reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS From 32 eligible studies, a total of 186 patients were included in the analysis. Patients who had favorable outcomes had higher mean pressure gradients (22.8 ± 11.5 mm Hg vs 17.4 ± 8.0 mm Hg, p = 0.033) and higher changes in pressure gradients after stent placement (19.4 ± 10.0 mm Hg vs 12.0 ± 6.0 mm Hg, p = 0.006) compared with those with unfavorable outcomes. The post-stent pressure gradients between the 2 groups were not significantly different (2.8 ± 4.0 mm Hg vs 2.7 ± 2.0 mm Hg, p = 0.934). In a multivariate stepwise logistic regression controlling for age, sex, body mass index, CSF opening pressure, pre-stent pressure gradient, and post-stent pressure gradient, the change in pressure gradient with stent placement was found to be an independent predictor of favorable outcome (p = 0.028). Using a pressure gradient of 21 as a cutoff, 81/86 (94.2%) of patients with a gradient > 21 achieved favorable outcomes, compared with 82/100 (82.0%) of patients with a gradient ≤ 21 (p = 0.022). CONCLUSIONS There appears to be a relationship between the pressure gradient of venous sinus stenosis and the success of VSS in IIH. A randomized controlled trial would help elucidate this relationship and potentially guide patient selection.

Comparing predicted and actual affective responses to process versus outcome: an emotion-as-feedback perspective.

Kwong, Jessica Y Y; Wong, Kin Fai Ellick; Tang, Suki K Y

One of the conjectures in affective forecasting literature is that people are advised to discount their anticipated emotions because their forecasts are often inaccurate. The present research distinguishes between emotional reactions to process versus those to outcome, and highlights an alternative view that affective misforecasts could indeed be adaptive to goal pursuit. Using an ultimatum game, Study 1 showed that people overpredicted how much they would regret and be disappointed by the amount of effort they exerted, should the outcomes turned out worse than expected; nonetheless, people could accurately predict their emotional responses to unfavorable outcomes per se. In a natural setting of a university examination, Study 2 demonstrated that actual regret and disappointment toward favorable outcomes were more intense than the level people expected, but this discrepancy was not observed in their emotional responses to efforts they had invested. These two distinct patterns of results substantiate the argument that the deviation between predicted and actual emotions is dependent on the referents of the emotional reactions.

Clinical relevance and biology of circulating tumor cells

PubMed Central

2011-01-01

Most breast cancer patients die due to metastases, and the early onset of this multistep process is usually missed by current tumor staging modalities. Therefore, ultrasensitive techniques have been developed to enable the enrichment, detection, isolation and characterization of disseminated tumor cells in bone marrow and circulating tumor cells in the peripheral blood of cancer patients. There is increasing evidence that the presence of these cells is associated with an unfavorable prognosis related to metastatic progression in the bone and other organs. This review focuses on investigations regarding the biology and clinical relevance of circulating tumor cells in breast cancer. PMID:22114869

Bradycardia is common during targeted temperature management, likely being a physiologic response to lower body temperature, and has recently been associated with favorable outcome following out-of-hospital cardiac arrest in smaller observational studies. The present study sought to confirm this finding in a large multicenter cohort of patients treated with targeted temperature management at 33°C and explore the response to targeted temperature management targeting 36°C. Post hoc analysis of a prospective randomized study. Thirty-six ICUs in 10 countries. We studied 447 (targeted temperature management = 33°C) and 430 (targeted temperature management = 36°C) comatose out-of-hospital cardiac arrest patients with available heart rate data, randomly assigned in the targeted temperature management trial from 2010 to 2013. Targeted temperature management at 33°C and 36°C. Endpoints were 180-day mortality and unfavorable neurologic function (cerebral performance category 3-5). Patients were stratified by target temperature and minimum heart rate during targeted temperature management (< 50, 50-59, and ≥ 60 beats/min [reference]) at 12, 20, and 28 hours after randomization. Heart rates less than 50 beats/min and 50-59 beats/min were recorded in 132 (30%) and 131 (29%) of the 33°C group, respectively. Crude 180-day mortality increased with increasing minimum heart rate (< 50 beats/min = 32%, 50-59 beats/min = 43%, and ≥ 60 beats/min = 60%; p(log-rank) < 0.0001). Bradycardia less than 50 beats/min was independently associated with lower 180-day mortality (hazard ratio(adjusted) = 0.50 [0.34-0.74; p < 0.001]) and lower odds of unfavorable neurologic outcome (odds ratio(adjusted) = 0.38 [ 0.21-0.68; p < 0.01]) in models adjusting for potential confounders including age, initial rhythm, time to return of spontaneous circulation, and lactate at admission. Similar, albeit less strong, independent associations of lower heart rates and favorable outcome were found in patients treated with targeted temperature management at 36°C. This study confirms an independent association of bradycardia and lower mortality and favorable neurologic outcome in a large cohort of comatose out-of-hospital cardiac arrest patients treated by targeted temperature management at 33°C. Bradycardia during targeted temperature management at 33°C may thus be a novel, early marker of favorable outcome.

Strongyloides stercoralis hyperinfection associated with impaired intestinal motility disorder

2015-01-01

Infection by Strongyloides stercoralis is a highly prevalent helminthiasis, which is mostly distributed in the tropical and subtropical regions of the world. Although a substantial number of cases are asymptomatic or paucisymtomatic, severe and life-threatening forms of this infection still occur and not infrequently is lately diagnosed. Gram-negative bacteria septicemia, which frequently accompanies the severe helminthiasis, contributes to the high mortality rate. Severe infection is invariably triggered by any imbalance in the host's immunity, favoring the auto-infective cycle, which increases the intraluminal parasite burden enormously. Clinical presentation of severe cases is varied, and diagnosis requires a high suspicion index. Acute abdomen has been reported in association with S. stercoralis infection, but intestinal necrosis is rarely found during the surgical approach. The authors report the case of a man who sought the emergency unit with recent onset abdominal pain. Clinical and imaging features were consistent with obstructive acute abdomen. Scattered adhesions and a necrotic ileal segment with a tiny perforation represented the surgical findings. The patient outcome was unfavorable and respiratory distress required an open lung biopsy. Both surgical specimens showed S. stercoralis infection. Unfortunately the patient underwent multiple organ failure and septicemia, and subsequently died. The authors call attention to the finding of intestinal necrosis and impaired intestinal motility disorder as possibilities for the diagnosis and risk factor, respectively, for a severe infection of S. stercoralis.

Purpose In about 1% of cases, incidental gallbladder cancers (iGBC) are found after routine cholecystectomy. The aim of this study is to compare clinical features of iGBC with benign GB disease and to evaluate factors affecting recurrence and survival. Methods Between January 1998 and March 2014, 4,629 patients received cholecystectomy and 73 iGBC patients (1.6%) were identified. We compared clinical features of 4,556 benign GB disease patients with 73 iGBC patients, and evaluated operative outcomes and prognostic factors in 56 eligible patients. Results The iGBC patients were older and concomitant diseases such as hypertension and anemia were more common than benign ones. And an age of more than 65 years was the only risk factor of iGBC. Adverse prognostic factors affecting patients' survival were age over 65, advanced histology, lymph node metastasis, and lymphovascular invasion on multivariate analysis. Age over 65 years, lymph node involvement, and lymphovascular invasion were identified as unfavorable factors affecting survival in subgroup analysis of extended cholecystectomy with bile duct resection (EC with BDR, n = 22). Conclusion Prior to routine cholecystectomy, incidental GB cancer should be suspected especially in elderly patients. And advanced age, lymph node metastasis, and lymphovascular invasion are important prognostic factors in EC with BDR cohorts. PMID:26942156

Synchronized cortical activity is implicated in both normative cognitive functioning and many neurologic disorders. For epilepsy patients with intractable seizures, irregular synchronization within the epileptogenic zone (EZ) is believed to provide the network substrate through which seizures initiate and propagate. Mapping the EZ prior to epilepsy surgery is critical for detecting seizure networks in order to achieve postsurgical seizure control. However, automated techniques for characterizing epileptic networks have yet to gain traction in the clinical setting. Recent advances in signal processing and spike detection have made it possible to examine the spatiotemporal propagation of interictal spike discharges across the epileptic cortex. In this study, we present a novel methodology for detecting, extracting, and visualizing spike propagation and demonstrate its potential utility as a biomarker for the EZ. Eighteen presurgical intracranial EEG recordings were obtained from pediatric patients ultimately experiencing favorable (i.e., seizure-free, n = 9) or unfavorable (i.e., seizure-persistent, n = 9) surgical outcomes. Novel algorithms were applied to extract multichannel spike discharges and visualize their spatiotemporal propagation. Quantitative analysis of spike propagation was performed using trajectory clustering and spatial autocorrelation techniques. Comparison of interictal propagation patterns revealed an increase in trajectory organization (i.e., spatial autocorrelation) among Sz-Free patients compared with Sz-Persist patients. The pathophysiological basis and clinical implications of these findings are considered. PMID:28066315

We evaluated the long-term outcomes of clinical stage IA non-small cell lung cancer (NSCLC) patients with combined pulmonary fibrosis and emphysema (CPFE) who underwent lobectomy. We reviewed the chest computed tomography (CT) findings and divided the patients into normal, fibrosis, emphysema and CPFE groups. We evaluated the relationships among the CT findings, the clinicopathological findings and postoperative survival. The patients were classified into the following groups based on the preoperative chest CT findings: normal lung, n = 187; emphysema, n = 62; fibrosis, n = 8; and CPFE, n = 17. The patients with CPFE were significantly older, more likely to be men and smokers, had a higher KL-6 level and lower FEV 1.0% value and had a higher rate of squamous cell carcinoma. The 5-year overall survival (OS) and disease-free survival rates were as follows: normal group, 82.5 and 76.8%; emphysema group, 80.0 and 74.9%; fibrosis group, 46.9 and 50%; and CPFE group, 36.9 and 27.9%, respectively (p < 0.01). A univariate and multivariate analysis determined that the pathological stage and CT findings were associated with OS. CPFE is a significantly unfavorable prognostic factor after lobectomy, even in early-stage NSCLC patients with a preserved lung function.

Background: Majority of health professionals have unfavorable attitudes toward the patients presenting with self-harm, which further compromises their therapeutic endeavors and outcomes. Objectives: This study was aimed to assess the medical students' attitudes toward suicide attempters. Materials and Methods: A cross-sectional study was conducted in a tertiary care medical institute of Haryana, a Northern state of India. Two hundred and five final year medical students were recruited through total enumeration method. “Suicide Opinion Questionnaire” was administered to assess their attitudes toward suicide attempters. Results: Only minority had previous exposure of managing any suicidal patient and attended suicide prevention programs. Majority agreed for suicide attempters being lonely and depressed. Nearly half of the students reported small family, disturbed interpersonal relationship, weak personality, self-punishment approach, cultural inhibitions in emotional expression, national instability, and disbelief in afterlife, as a major push to attempt suicide. Compared to boys, girls reported the greater contribution of weak personality and self-destructive behaviors and lesser contribution of family disturbances and religious convictions as suicide triggers. They held favorable attitude for only one-third of the attitudinal statement, and they were uncertain for two-third of the attitudinal statements. Conclusions: Such a high proportion of uncertain responses imply toward lack of awareness and clinical expertise for managing suicide attempters. It also signifies the urgent need for enhancing their educational and clinical exposure, to improve their attitudes toward patients presenting with self-harm. PMID:28163403

Purpose: To evaluate the applicability of carbon ion beams for the treatment of choroidal melanoma with regard to normal tissue morbidity and local tumor control. Methods and Materials: Between January 2001 and February 2006, 59 patients with locally advanced or unfavorably located choroidal melanoma were enrolled in a Phase I/II clinical trial of carbon-ion radiotherapy at the National Institute of Radiologic Sciences. The primary endpoint of this study was normal tissue morbidity, and secondary endpoints were local tumor control and patient survival. Of the 59 subjects enrolled, 57 were followed >6 months and analyzed. Results: Twenty-three patients (40%) developed neovascularmore » glaucoma, and three underwent enucleation for eye pain due to elevated intraocular pressure. Incidence of neovascular glaucoma was dependent on tumor size and site. Five patients had died at analysis, three of distant metastasis and two of concurrent disease. All but one patient, who developed marginal recurrence, were controlled locally. Six patients developed distant metastasis, five in the liver and one in the lung. Three-year overall survival, disease-free survival, and local control rates were 88.2%, 84.8%, and 97.4%, respectively. No apparent dose-response relationship was observed in either tumor control or normal tissue morbidity at the dose range applied. Conclusion: Carbon-ion radiotherapy can be applied to choroidal melanoma with an acceptable morbidity and sufficient antitumor effect, even with tumors of unfavorable size or site.« less

The high rates of cigarette smoking among depressed persons may be partially explained by increased positive expectancies for cigarette smoking among this population. In view of theoretical and empirical work on depressed people's negative views of the future, though, it would be expected that depressed smokers would hold particularly negative expectancies about the effects of cigarette smoking. The two current studies examined the relations between depression and smoking outcome expectancies in (a) a general population of adult regular smokers and (b) adult smokers seeking to quit smoking. Depressive symptoms and depression proneness both showed significant positive correlations with positive expectancies for cigarette smoking. Several positive correlations with negative expectancies also emerged. Thus, experiencing depressive symptoms may serve to amplify both favorable and unfavorable expectancies about the effects of smoking.

Background Little evidence guides the appropriate duration of resuscitation in out-of-hospital cardiac arrest (OHCA), and case features justifying longer or shorter durations are ill-defined. We estimated the impact of resuscitation duration on the probability of favorable functional outcome in OHCA using a large, multi-center cohort. Methods Secondary analysis of a North American, single blind, multi-center, cluster-randomized clinical trial (ROC-PRIMED) of consecutive adults with non-traumatic, EMS-treated, OHCA. Primary exposure was duration of resuscitation in minutes (onset of professional resuscitation to return of spontaneous circulation [ROSC] or termination of resuscitation). Primary outcome was survival to hospital discharge with favorable outcome (modified Rankin scale [mRS] 0-3). Subjects were additionally classified as survival with unfavorable outcome (mRS 4-5), ROSC without survival (mRS 6), or without ROSC. Subject accrual was plotted as a function of resuscitation duration, and the dynamic probability of favorable outcome at discharge was estimated for the whole cohort and subgroups. Adjusted logistic regression models tested the association between resuscitation duration and survival with favorable outcome. Results The primary cohort included 11,368 subjects (median age 69 years [IQR: 56-81 years]; 7,121 men [62.6%]). Of these, 4,023 (35.4%) achieved ROSC, 1,232 (10.8%) survived to hospital discharge, and 905 (8.0%) had mRS 0-3 at discharge. Distribution of CPR duration differed by outcome (p<0.00001). For CPR duration up to 37.0 minutes (95%CI 34.9-40.9 minutes), 99% with eventual mRS 0-3 at discharge achieved ROSC. Dynamic probability of mRS 0-3 at discharge declined over elapsed resuscitation duration, but subjects with initial shockable cardiac rhythm, witnessed cardiac arrest, and bystander CPR were more likely to survive with favorable outcome after prolonged efforts (30-40 minutes). Adjusting for prehospital (OR 0.93; 95%CI 0.92-0.95) and inpatient (OR 0.97; 95%CI 0.95-0.99) covariates, resuscitation duration was associated with survival to discharge with mRS 0-3. Conclusions Shorter resuscitation duration was associated with likelihood of favorable outcome at hospital discharge. Subjects with favorable case features were more likely to survive prolonged resuscitation up to 47 minutes. PMID:27760796

Both Epstein-Barr and measles viruses (MV) cause immune suppression, and the association of the two viruses is evaluated as life threatening. The cell immune impairment caused by simultaneous Epstein-Barr and measles viral infections was responsible for the complicated course of the disease in all described previously reports and for unfavorable outcomes in most of the cases. Timely diagnosis of coincidental viral infections could be a useful predictor for the clinical course and complications. Diagnosis must be based on an accurate assessment of clinical, hematologic, serologic manifestations and supported by appropriate laboratory methods. Recognizing the infectious etiology of concomitant infections is important for both clinicians and epidemiologists. To describe a case report of a 20-year-old woman previously vaccinated against measles infected with acute mononucleosis and coincidental measles virus infection. The clinical, routine laboratory, as well as serological and virologic findings of this patient were scrutinized. Special emphasis was placed on the use of RT-PCR/PCR for confirming the involvement of both measles virus and Epstein-Barr virus (EBV) in this patient's illness. Infectious mononucleosis was not suspected at admission to the hospital. The final diagnosis of a concomitant measles virus infection and acute infectious mononucleosis was facilitated using viral serology to detect virus-specific IgG and IgM antibodies and by RT-PCR for the detection of measles virus RNA and EBV DNA from peripheral blood monocyte cells (PBMC). The present report highlights the difficulty of diagnosing two coincidental virus infections on clinical grounds. Serological and molecular laboratory methods, specifically the PCR (RT-PCR) analysis, are found to be useful for confirming the concomitant viral infections and proper identification of the infecting pathogens.

Differences in payer evaluation and coverage of pharmaceuticals and medical procedures suggest that coverage may differ for medications and procedures independent of their clinical benefit. We hypothesized that coverage for medications is more restricted than corresponding coverage for nonmedication interventions. We included top-selling medications and highly utilized procedures. For each intervention-indication pair, we classified value in terms of cost-effectiveness (incremental cost per quality-adjusted life-year), as reported by the Tufts Medical Center Cost-Effectiveness Analysis Registry. For each intervention-indication pair and for each of 10 large payers, we classified coverage, when available, as either "more restrictive" or as "not more restrictive," compared with a benchmark. The benchmark reflected the US Food and Drug Administration label information, when available, or pertinent clinical guidelines. We compared coverage policies and the benchmark in terms of step edits and clinical restrictions. Finally, we regressed coverage restrictiveness against intervention type (medication or nonmedication), controlling for value (cost-effectiveness more or less favorable than a designated threshold). We identified 392 medication and 185 procedure coverage decisions. A total of 26.3% of the medication coverage and 38.4% of the procedure coverage decisions were more restrictive than their corresponding benchmarks. After controlling for value, the odds of being more restrictive were 42% lower for medications than for procedures. Including unfavorable tier placement in the definition of "more restrictive" greatly increased the proportion of medication coverage decisions classified as "more restrictive" and reversed our findings. Therapy access depends on factors other than cost and clinical benefit, suggesting potential health care system inefficiency.

Pediatric-onset multiple sclerosis (POMS) may represent a model of vulnerability to damage occurring during a period of active maturation of the human brain. Whereas adaptive mechanisms seem to take place in the POMS brain in the short-medium term, natural history studies have shown that these patients reach irreversible disability, despite slower progression, at a significantly younger age than adult-onset MS (AOMS) patients. We tested for the first time whether significant brain alterations already occurred in POMS patients in their early adulthood and with no or minimal disability ( n  = 15) in comparison with age- and disability-matched AOMS patients ( n  = 14) and to normal controls (NC, n  = 20). We used a multimodal MRI approach by modeling, using FSL, voxelwise measures of microstructural integrity of white matter tracts and gray matter volumes with those of intra- and internetwork functional connectivity (FC) (analysis of variance, p  ≤ 0.01, corrected for multiple comparisons across space). POMS patients showed, when compared with both NC and AOMS patients, altered measures of diffusion tensor imaging (reduced fractional anisotropy and/or increased diffusivities) and higher probability of lesion occurrence in a clinically eloquent region for physical disability such as the posterior corona radiata. In addition, POMS patients showed, compared with the other two groups, reduced long-range FC, assessed from resting functional MRI, between default mode network and secondary visual network, whose interaction subserves important cognitive functions such as spatial attention and visual learning. Overall, this pattern of structural damage and brain connectivity disruption in early adult POMS patients with no or minimal clinical disability might explain their unfavorable clinical outcome in the long term.

Transplantation of alginate-encapsulated islets has the potential to treat patients suffering from type I diabetes, a condition characterized by an autoimmune attack against insulin-secreting beta cells. However, there are multiple immunological challenges associated with this procedure, all of which must be adequately addressed prior to translation from trials in small animal and nonhuman primate models to human clinical trials. Principal threats to graft viability include immune-mediated destruction triggered by immunogenic alginate impurities, unfavorable polymer composition and surface characteristics, and release of membrane-permeable antigens, as well as damage associated molecular patterns (DAMPs) by the encapsulated islets themselves. The lack of standardization of significant parameters of bioencapsulation device design and manufacture (i.e., purification protocols, surface-modification grafting techniques, alginate composition modifications) between labs is yet another obstacle that must be overcome before a clinically effective and applicable protocol for encapsulating islets can be implemented. Nonetheless, substantial progress is being made, as is evident from prolonged graft survival times and improved protection from immune-mediated graft destruction reported by various research groups, but also with regard to discoveries of specific pathways involved in explaining observed outcomes. Progress in the latter is essential for a comprehensive understanding of the mechanisms responsible for the varying levels of immunogenicity of certain alginate devices. Successful translation of encapsulated islet transplantation from in vitro and animal model testing to human clinical trials hinges on application of this knowledge of the pathways and interactions which comprise immune-mediated rejection. Thus, this review not only focuses on the different factors contributing to provocation of the immune reaction by encapsulated islets, but also on the defining characteristics of the response itself.

Mitochondrial genome (mtDNA) content is depleted in many cancers. In prostate cancer, there is intra-glandular as well as inter-patient mtDNA copy number variation. In this study, we determine if mtDNA content can be used as a predictor for prostate cancer staging and outcomes. Fresh prostate cancer biopsies from 115 patients were obtained at time of surgery. All cores underwent pathological review, followed by isolation of cancer and normal tissue. DNA was extracted and qPCR performed to quantify the total amount of mtDNA as a ratio to genomic DNA. Differences in mtDNA content were compared for prostate cancer pathology features and disease outcomes. We showed a significantly reduced mtDNA content in prostate cancer compared with normal adjacent prostate tissue (mean difference 1.73-fold, P-value <0.001). Prostate cancer with increased mtDNA content showed unfavorable pathologic characteristics including, higher disease stage (PT2 vs PT3 P-value = 0.018), extracapsular extension (P-value = 0.02) and a trend toward an increased Gleason score (P-value = 0.064). No significant association was observed between changes in mtDNA content and biochemical recurrence (median follow up of 107 months). Contrary to other cancer types, prostate cancer tissue shows no universally depleted mtDNA content. Rather, the change in mtDNA content is highly variable, mirroring known prostate cancer genome heterogeneity. Patients with high mtDNA content have an unfavorable pathology, while a high mtDNA content in normal adjacent prostate tissue is associated with worse prognosis. © 2017 Wiley Periodicals, Inc.

Growth and nutritional intake of children with cows' milk allergy and other food allergens has been thoroughly investigated in recent years across many different countries and age groups. An impaired growth in atopic children should not be attributed only to a high number of allergens and foods to be avoided, but to a general condition of 'sub-inflammation', which unfavorably affects the absorption and utilization of fuel and substrates. Atopic study participants may represent a good target for personalized nutrition and in this review we sought to outline many of the issues that should be taken into account when dietitians advise patients regarding food avoidance and expected effects on growth. The dietary management of food allergy requires appropriate dietary choices to maintain adequate growth, starting with special formulas in infancy. An emerging area of research is the fussy eating related to the exclusion of cow's milk and other foods during infancy and the long-term effects on eating habits and food preferences. Study participants with either mono or polyallergic diseases should ideally undergo the definition of their allergic and metabolic characteristics, to precisely adjust dietary interventions on an individual basis to support the genetic potential of growth and prevent unfavorable outcomes.

Intracerebral hemorrhage (ICH) is a devastating subtype of stroke. Patients with ICH have poor functional outcomes. The association between blood glucose level and functional outcome in ICH remains unclear. This systematic review and meta-analysis aimed to investigate the association between blood glucose level and functional outcomes in patients with ICH. Literature was searched systemically in PubMed, EMBASE, Web of Science, and Cochrane Library. Published cohort studies evaluating the association between blood glucose and functional outcome in patients with ICH were included. This meta-analysis was performed using odds ratios (ORs) and 95% confidence intervals (CIs). A total of 16 studies were included in our meta-analysis. Our data show that hyperglycemia defined by cutoff values was significantly associated with unfavorable functional outcome (OR, 1.80; 95% CI, 1.36-2.39; P < 0.001). Our analysis also suggested a significant association between increased blood glucose levels and functional outcomes (OR, 1.05; 95% CI, 1.03-1.07; P < 0.001). High blood glucose level is significantly associated with poor functional outcome in ICH. Further studies with larger sample sizes, more time points, and longer follow-up times are necessary to confirm this association. Copyright © 2018 Elsevier Inc. All rights reserved.

Genomic abnormalities, such as deletions in 11q22 or 17p13, are associated with poorer prognosis in patients with chronic lymphocytic leukemia (CLL). We hypothesized that unknown regions of copy number variation (CNV) affect clinical outcome and can be detected by array-based single-nucleotide polymorphism (SNP) genotyping. We compared SNP genotypes from 168 untreated patients with CLL with genotypes from 73 white HapMap controls. We identified 322 regions of recurrent CNV, 82 of which occurred significantly more often in CLL than in HapMap (CLL-specific CNV), including regions typically aberrant in CLL: deletions in 6q21, 11q22, 13q14, and 17p13 and trisomy 12. In univariate analyses, 35 of total and 11 of CLL-specific CNVs were associated with unfavorable time-to-event outcomes, including gains or losses in chromosomes 2p, 4p, 4q, 6p, 6q, 7q, 11p, 11q, and 17p. In multivariate analyses, six CNVs (ie, CLL-specific variations in 11p15.1-15.4 or 6q27) predicted time-to-treatment or overall survival independently of established markers of prognosis. Moreover, genotypic complexity (ie, the number of independent CNVs per patient) significantly predicted prognosis, with a median time-to-treatment of 64 months versus 23 months in patients with zero to one versus two or more CNVs, respectively (P = 3.3 × 10−8). In summary, a comparison of SNP genotypes from patients with CLL with HapMap controls allowed us to identify known and unknown recurrent CNVs and to determine regions and rates of CNV that predict poorer prognosis in patients with CLL.

The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity caused by conventional medications as well as herbals and dietary supplements (HDS). To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The study took place among eight U.S. referral centers that are part of the DILIN. Consecutive patients with liver injury referred to a DILIN center were eligible. The final sample comprised 130 (15.5%) of all subjects enrolled (839) who were judged to have experienced liver injury caused by HDS. Hepatotoxicity caused by HDS was evaluated by expert opinion. Demographic and clinical characteristics and outcome assessments, including death and liver transplantation (LT), were ascertained. Cases were stratified and compared according to the type of agent implicated in liver injury; 45 had injury caused by bodybuilding HDS, 85 by nonbodybuilding HDS, and 709 by medications. Liver injury caused by HDS increased from 7% to 20% (P < 0.001) during the study period. Bodybuilding HDS caused prolonged jaundice (median, 91 days) in young men, but did not result in any fatalities or LT. The remaining HDS cases presented as hepatocellular injury, predominantly in middle-aged women, and, more frequently, led to death or transplantation, compared to injury from medications (13% vs. 3%; P < 0.05). The proportion of liver injury cases attributed to HDS in DILIN has increased significantly. Liver injury from nonbodybuilding HDS is more severe than from bodybuilding HDS or medications, as evidenced by differences in unfavorable outcomes (death and transplantation).

To assess the impact of preoperatively estimated prostate volume (PV) using transrectal ultrasonography (TRUS) on surgical and oncological outcomes in robot-assisted radical prostatectomy (RARP). We analyzed the experience of a single surgeon at our hospital who performed 436 RARPs without neoadjuvant hormone therapy between August 2006 and December 2013. Patients were divided into three groups according to their preoperative PV calculated using TRUS (PV ≤ 20 cm(3): group 1, n = 61; 20 < PV < 50 cm(3): group 2, n = 303; PV ≥ 50 cm(3): group 3, n = 72). Blood loss was significantly higher in group 3 than in group 1 and group 2. In stage pT2 patients, the rate of positive surgical margin (PSM) was significantly lower in group 3 than in group 1. In addition, perioperative complications significantly increased with increasing PV, while the extraprostatic extension (EPE) rate significantly decreased with increasing PV. The preoperative biopsy Gleason score, prostate-specific antigen (PSA) density, and clinical T2 stage were inversely correlated with increasing PV. Biochemical recurrence-free survival after RARP was significantly lower in group 1 than in groups 2 and 3. A large prostate size was significantly associated with increased blood loss and a higher rate of perioperative complications. A small prostate size was associated with a higher PSM rate, PSA density, Gleason score, EPE rate, and biochemical recurrence rate. These results suggest that RARP was technically challenging in patients with large prostates, whereas small prostates were associated with unfavorable oncological outcomes.

Although some studies have assessed the prognostic value of HOTAIR in patients with digestive system tumors, the relationship between the HOTAIR and outcome of digestive system tumors remains unknown. The PubMed was searched to identify the eligible studies. Here, we performed a meta-analysis with 11 studies, including a total of 903 cases. Pooled hazard ratios (HRs) and 95 % confidence interval (CI) of HOTAIR for cancer survival were calculated. We found that the pooled HR elevated HOTAIR expression in tumor tissues was 2.36 (95 % CI 1.88-2.97) compared with patients with low HOTAIR expression. Moreover, subgroup analysis revealed that HOTAIR overexpression was also markedly associated with short survival for esophageal squamous cell carcinoma (HR 2.19, 95 % CI 1.62-2.94) and gastric cancer (HR 1.66, 95 % CI 1.02-2.68). In addition, up-regulated HOTAIR was significantly related to survival of digestive system cancer among the studies with more follow-up time (follow time ≥ 5 years) (HR 2.51, 95 % CI 1.99-3.17). When stratified by HR resource and number of patients, the result indicated consistent results with the overall analysis. Subgroup analysis on ethnicities did not change the prognostic influence of elevated HOTAIR expression. Additionally, we conducted an independent validation cohort including 71 gastric cancer cases, in which patients with up-regulated HOTAIR expression had an unfavorable outcome with HR of 2.10 (95 % CI 1.10-4.03). The results suggest that aberrant HOTAIR expression may serve as a candidate positive marker to predict the prognosis of patients with carcinoma of digestive system.

Hemangiopericytoma (HPC) is a rare mesenchymal tumor that tends to affect the central nervous system and is associated with distant metastasis and a high recurrence rate. The purpose of this study was to analyze the prognostic factors in patients with primary HPC who received surgical treatment. This retrospective study reviewed all adult patients with primary HPC of the central nervous system treated from 2001 to 2009 at our institution. Clinical information, adjuvant radiation, and expression levels of Ki-67 and p53 were correlated with patient outcomes. The final analysis included 103 patients. The mean follow-up period was 75.9 months ± 36.5 (range, 1-165 months). There was a significant difference in progression-free survival (PFS) (P < 0.001) and overall survival (P = 0.014) between patients who underwent gross total resection versus subtotal resection. Expression of p53 was found in 48.5% of patients and showed utility as an independent unfavorable prognostic factor for PFS (P = 0.006). Multivariate analysis revealed that only extent of tumor resection (P = 0.004) and p53 expression (P = 0.024) were independent prognostic factors for PFS. Adjuvant radiation was found to extend PFS only in the p53-negative expression group (P = 0.044). Gross total resection significantly improves the outcome of patients with primary HPCs, whereas adjuvant radiation contributes significantly to PFS only in patients with negative p53 expression and in patients with incomplete resections. Extent of resection and p53 expression may serve as prognostic markers for the outcome of patients with primary HPC. Copyright © 2016 Elsevier Inc. All rights reserved.

Intracranial pressure (ICP) monitoring represents an important tool in the management of traumatic brain injury (TBI). Although current information exists regarding ICP monitoring in secondary decompressive craniectomy (DC), little is known after primary DC following emergency hematoma evacuation. Retrospective analysis of prospectively collected data. Inclusion criteria were age ≥18 years and admission to the intensive care unit (ICU) for TBI and ICP monitoring after primary DC. Exclusion criteria were ICU length of stay (LOS) <1 day and pregnancy. Major objectives were: (1) to analyze changes in ICP/cerebral perfusion pressure (CPP) after primary DC, (2) to evaluate the relationship between ICP/CPP and neurological outcome and (3) to characterize and evaluate ICP-driven therapies after DC. A total of 34 patients were enrolled. Over 308 days of ICP/CPP monitoring, 130 days with at least one episode of intracranial hypertension (26 patients, 76.5%) and 57 days with at least one episode of CPP <60 mmHg (22 patients, 64.7%) were recorded. A statistically significant relationship was discovered between the Glasgow Outcome Scale (GOS) scores and mean post-decompression ICP (p < 0.04) and between GOS and CPP minimum (CPPmin) (p < 0.04). After DC, persisting intracranial hypertension was treated with: barbiturate coma (n = 7, 20.6%), external ventricular drain (EVD) (n = 4, 11.8%), DC diameter widening (n = 1, 2.9%) and removal of newly formed hematomas (n = 3, 8.8%). Intracranial hypertension and/or low CPP occurs frequently after primary DC; their occurence is associated with an unfavorable neurological outcome. ICP monitoring appears useful in guiding therapy after primary DC.

In patients with hepatocellular carcinoma (HCC), gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) often identifies non-hypervascular hypointense hepatic nodules during the hepatobiliary phase, but their prognostic significance is unclear. We conducted a prospective observational study to investigate the impact of non-hypervascular hypointense hepatic nodules detected by Gd-EOB-DTPA-enhanced MRI on the outcome of patients with early-stage HCC. Post-treatment recurrence and survival rates were analyzed in 138 patients with non-recurrent, early-stage HCC [Barcelona Clinic Liver Cancer (BCLC) stage 0 or A] and Child-Pugh A liver function according to the presence of non-hypervascular hypointense nodules on pretreatment Gd-EOB-DTPA-enhanced MRI. Non-hypervascular hypointense hepatic nodules were detected in 51 (37.0%) patients with early-stage HCC on pretreatment Gd-EOB-DTPA-enhanced MRI. Recurrence rates were significantly higher in patients with non-hypervascular hypointense nodules (p < 0.0001). Based on a multivariate analysis, the presence of non-hypervascular hypointense hepatic nodules on Gd-EOB-DTPA-enhanced MRI was independently associated with an increased recurrence rate, independent of tumor progression or treatment (p = 0.0005). The survival rate was significantly lower in patients with non-hypervascular hypointense nodules on Gd-EOB-DTPA-enhanced MRI (p = 0.0108). In patients with early-stage typical HCC (BCLC 0 or A), the presence of concurrent non-hypervascular hypointense hepatic nodules in the hepatobiliary phase of pretreatment Gd-EOB-DTPA-enhanced MRI is an indicator of higher likelihood of recurrence after treatment and may be a marker for unfavorable outcome.

Aim To identify gene-expression signatures predicting cytarabine response by an integrative analysis of multiple clinical and pharmacological end points in acute myeloid leukemia (AML) patients. Materials & methods We performed an integrated analysis to associate the gene expression of diagnostic bone marrow blasts from acute myeloid leukemia (AML) patients treated in the discovery set (AML97; n = 42) and in the independent validation set (AML02; n = 46) with multiple clinical and pharmacological end points. Based on prior biological knowledge, we defined a gene to show a therapeutically beneficial (detrimental) pattern of association of its expression positively (negatively) correlated with favorable phenotypes such as intracellular cytarabine 5´-triphosphate levels, morphological response and event-free survival, and negatively (positively) correlated with unfavorable end points such as post-cytarabine DNA synthesis levels, minimal residual disease and cytarabine LC50. Results We identified 240 probe sets predicting a therapeutically beneficial pattern and 97 predicting detrimental pattern (p ≤ 0.005) in the discovery set. Of these, 60 were confirmed in the independent validation set. The validated probe sets correspond to genes involved in PIK3/PTEN/AKT/mTOR signaling, G-protein-coupled receptor signaling and leukemogenesis. This suggests that targeting these pathways as potential pharmacogenomic and therapeutic candidates could be useful for improving treatment outcomes in AML. Conclusion This study illustrates the power of integrated data analysis of genomic data as well as multiple clinical and pharmacologic end points in the identification of genes and pathways of biological relevance.

Clinical practice guidelines for community-acquired pneumonia (CAP) contribute to improve patient's management. CAP undergoes continuous changes in etiology, epidemiology and antimicrobial sensitivity, requiring periodic guidelines revisions. An inter-society committee designed this guidelines dividing it into several topics based on prior guidelines and recent clinical studies. CAP compromises annually more than 1% of the population; most of the cases only require outpatient care but others are severe cases, reaching the 6th cause of death in Argentina. The cases are distributed unevenly into ambulatory, admitted in the general ward or in the intensive care unit. There is no way to predict the etiology. Unfavorable outcome predictors include age, antecedents and physical, laboratory and radiography findings. Ten to 25% of inpatients need to be admitted to the intensive care unit at the onset or during the follow-up, for mechanical ventilation or hemodynamic support (severe CAP). Severe CAP is associated with high mortality and requires adequate and urgent therapy. Pregnant, COPD and nursing home patients require special recommendations. Diagnosis is clinical, while complementary methods are useful to define etiology and severity; chest X-ray is the only one universally recommended. Other studies, including microbiologic evaluation are particularly appropriate in the hospitalized patients. The initial therapy is empiric, it must begin early, using antimicrobials active against the target microorganisms, avoiding their inappropriate use which can lead to the development of resistance. Length of therapy must not be unnecessarily prolonged. Hydratation, nutrition, oxygen and therapy of complications must complement antibiotic treatment. Prevention is based on influenza prophylaxis, anti-pneumococcal vaccine, aspiration prevention and other general measures.

Resection line infiltration (RLI) after surgical treatment represents an unfavorable prognostic factor in advanced gastric cancer. We performed a retrospective analysis of 89 patients with resection line involvement who did not undergo reoperation. On behalf of the Italian Research Group for Gastric Cancer, we present the characteristics and outcome of 89 patients who were submitted to surgical resection for gastric cancer from 1988 to 2001 and did not undergo reoperation because of disease extension or associated pathologies. RLI was significantly higher in patients with T4 tumors and diffuse histological type. Anastomotic leakages were observed in 4.8% of infiltrated esophageal resection margins, whereas 1.9% of infiltrated duodenal resection lines showed duodenal fistulas. Five-year overall survival of patients with RLI was 29%. Prognosis was not affected by RLI in early forms (100% 5-year survival); however, 5-year survival in T2 and T3 stages was significantly lower with respect to the same stages without residual tumor. The influence of RLI on prognosis was confirmed in N0 as well as in N1 and N2 patients. RLI also was an independent prognostic at multivariate analysis (odds ratio = 1.5; 95% confidence interval, 1.08-2.08; P = 0.0144). RLI significantly affects long-term survival of advanced gastric cancer. The impact on prognosis is independent of lymph node involvement. Patients in good general condition for whom radical surgery is possible should be considered for reoperation.

Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. The natural history of untreated significant TR portends an unfavorable outcome, but only a minority of patients is currently referred for surgical treatment. Organic TR (caused by primary abnormality of the leaflets) is relatively infrequent whereas secondary or functional TR (caused by dilatation of the tricuspid annulus, right ventricle [RV] and right atrium) is the predominant mechanism. The success of transcatheter therapies for left valvular heart disease over the last decade, has fueled similar development of novel transcatheter devices for the treatment of TR. Currently being tested in several clinical trials, each of these devices requires specific needs to define the procedural suitability. In addition, an accurate evaluation of the complex tricuspid anatomy, RV geometry and their relationship with the surrounding structures is mandatory. Therefore, accurate pre-procedural assessment using multimodality imaging techniques will undoubtedly play a pivotal role in achieving procedural success and safety. This review article provides a comprehensive overview on the etiology and different mechanisms of TR, and highlights the role of multimodality imaging techniques in the assessment of TR severity, RV dysfunction and fulfilment of device-specific selection criteria.

The use of flow arrest as a means of providing cerebral protection during carotid angioplasty offers the advantages of improved efficiency of debris removal and the ability to provide protection under unfavorable (tortuous) anatomic circumstances. However, in contrast to the filtration methods of cerebral protection, this modality requires complete interruption of antegrade carotid artery flow during balloon angioplasty and stent deployment. We report our experience with 9 patients undergoing carotid angioplasty with the Mo.Ma device, which utilizes common and external carotid artery balloon occlusion during the angioplasty procedure. We assessed the clinical outcomes and intraprocedural hemodynamic data. The average duration of carotid occlusion was 8.3 minutes. Of the 9 patients, 2 patients (22%) experienced cerebral intolerance. No stroke occurred in this patient cohort. There appeared to be a poor relationship between procedure intolerance and the presence of significant contralateral stenosis or low carotid back pressure. Furthermore, the incidence of postangioplasty hypotension was not clearly related to cerebral intolerance. Carotid angioplasty with stenting can be safely conducted with flow arrest as an alternative to filter-type cerebral protection devices. However, because cerebral intolerance is not an infrequent occurrence with this approach, clinicians must be cognizant of management strategies for transient cerebral intolerance.

The 7q31 locus contains several genes affected in cancer progression. Although evidences exist regarding its impact on tumorigenesis, the role of genetic alterations and the expressions of locus-related genes are still controversial. Our study aimed to define the 7q31 copy number alterations in primary melanomas, primary-metastatic tumor pairs and cell lines. Data were correlated with clinical-pathological parameters. Genetic data show that 7q31 copy number distribution was heterogeneous in both primary and metastatic tumors. Extra copies were highly accompanied by chromosome 7 polisomy, and significantly increased in primary lesions with poor prognosis. Additionally, we determined the mRNA and protein levels of the locus-related CAV1 and TES genes. TES mRNA level was associated with metastatic location. CAV1 mRNA and protein levels were significantly higher in thicker tumors, however, lack of protein was also observed in a subpopulation of thin lesions. Expressions of CAV1 and TES were not associated with 7q31 alterations. In conclusion, 7q31 amplification can predict unfavorable outcome. Alterations of TES mRNA level may predict the location of metastasis. CAV1 possibly affect the cancer cell invasion.

To explore the correlation between serum levels of Tumor Associated Materials (TAM) and clinicopathological parameters and prognosis in patients with esophageal cancer (EC). The levels of TAM were determined by chemical colorimetry in 100 EC patients and 100 healthy controls. Serum TAM levels were significantly higher in patients with esophageal carcinoma than in the control group (p < 0.001). High levels of TAM were associated with tumor size (p = 0.004), tumor depth (p < 0.001), stage (p < 0.001), lymph node metastases (p < 0.001), tumor differentiation (p = 0.001), tumor respectability (p = 0.002) and disease progression (p < 0.001). The poor prognostic outcomes were correlated with an elevated level of TAM (p = 0.001). Kaplan-Meier analysis showed patients with increased levels of TAM after operation had an lower overall survival (p < 0.001) and disease-free survival (p < 0.001). In addition, multivariate Cox proportional hazard analyses revealed that TAM may be an independent factor affecting the overall survival and disease-free survival (p < 0.001). The detection of TAM could be used to screen for tumor and assess unfavorable prognosis in patients with EC.

Predictors of unfavorable outcome in patients after cardiopulmonary arrest (CPA) are important to make decisions about the limitation of therapeutic efforts. The aim was to analyze the clinical variables in the prognosis of patients recovered after CPA. Retrospective study on comatose patients with recovered CPA. The variables were: age, sex, Glasgow Coma Score (GCS), pupillary light reflex, other variables related to CPA (cause, duration, witnessed or not witnessed), myoclonic status and electroencephalographic (EEG) patterns. Fifty patients were studied. The variables associated with mortality were the absence of pupillary light reflex (hazard ratio [HR] 0.277, 95% confidence interval [95% CI] 0.103-0.741, P=.01), a low GCS (HR 0.701, 95% CI 0.542-0.908, P=.007) and myoclonic state (HR 0.38, 95% CI 0.176-0.854, P=.01). We evaluated the EEG patterns in 22 patients. No statistical significance was observed. The absence of pupillary light reflex, a low GCS and myoclonic state are prognostic factors in patients recovered after a CPA. The EEG patterns showed a nonsignificant association with prognosis.

In March 2017, the ACGME relaxed resident duty-hour restrictions to allow first-year residents to work 24-hour shifts, affecting the internship experience of incoming radiology residents. The aim of this study was to assess the media response to this duty-hour change, comparing news articles with favorable and unfavorable views. Google News was used to identify 36 relevant unique news articles published over a 4-week period after the announcement. Articles' stance was categorized as favorable, unfavorable, or neutral. Additional article characteristics were explored. Article sources were 58% national, 22% local, and 20% medical news. Article stance was most commonly unfavorable for national news sources (48%), compared with neutral for local (62%) and medical (72%) news sources. Most common reasons for unfavorable stance were sleep deprivation (n = 11), medical errors (n = 11), residents' health (n = 9), risk for car accidents (n = 9), a patriarchal hazing system (n = 6), and work-life balance (n = 5). Most common reasons for favorable stance were impact on resident education (n = 7) and continuity of care (n = 7). Supporting data were cited by 38% of unfavorable and 100% of favorable articles. Unfavorable articles most commonly quoted physicians affiliated with resident advocacy groups; favorable articles most commonly quoted physicians affiliated with the ACGME. The relaxed duty-hour restrictions received an overall unfavorable media response, particularly in nonmedical news sources, driven by concerns regarding sleep-deprived doctors. Favorable articles ubiquitously cited data supporting the safety of relaxed duty hour restrictions. Further research is warranted to better understand the impact of relaxed resident duty-hour limits on sleep deprivation, residents' health and education, and the quality of patient care.

Approximately 20-40% of outpatients with diabetes experience elevated levels of emotional distress, varying from disease-specific distress to general symptoms of anxiety and depression. The patient's emotional well-being is related to other unfavorable outcomes, like reduced quality of life, sub-optimal self-care, impaired glycemic control, higher risk of complications, and increased mortality rates. The purpose of this study is to test the effectiveness of a new diabetes-specific, mindfulness-based psychological intervention. First, with regard to reducing emotional distress; second, with respect to improving quality of life, dispositional mindfulness, and self-esteem of patients with diabetes; third, with regard to self-care and clinical outcomes; finally, a potential effect modification by clinical and personality characteristics will be explored. The Diabetes and Mindfulness study (DiaMind) is a randomized controlled trial. Patients with diabetes with low levels of emotional well-being will be recruited from outpatient diabetes clinics. Eligible patients will be randomized to an intervention group or a wait-list control group. The intervention group will receive the mindfulness program immediately, while the control group will receive the program eight months later. The primary outcome is emotional distress (anxiety, stress, depressive symptoms), for which data will be collected at baseline, four weeks, post intervention, and after six months follow-up. In addition, self-report data will be collected on quality of life, dispositional mindfulness, self-esteem, self-care, and personality, while complications and glycemic control will be assessed from medical files and blood pressure will be measured. Group differences will be analyzed with repeated measures analysis of covariance.The study is supported by grants from the Dutch Diabetes Research Foundation and Tilburg University and has been approved by a medical ethics committee. It is hypothesized that emotional well-being, quality of life, dispositional mindfulness, self-esteem, self-care, and blood pressure will improve significantly more in the mindfulness group compared to the control group. Results of this study can contribute to a better care for patients with diabetes with lowered levels of emotional well-being. It is expected that the first results will become available in 2012.

In social gaming networks, the current research focus has been on the origin of widespread reciprocal behaviors when individuals play non-cooperative games. In this paper, we investigate the topological properties of unfavorable individuals in evolutionary games. The unfavorable individuals are defined as the individuals gaining the lowest average payoff in a round of game. Since the average payoff is normally considered as a measure of fitness, the unfavorable individuals are very likely to be eliminated or change their strategy updating rules from a Darwinian perspective. Considering that humans can hardly adopt a unified strategy to play with their neighbors, we propose a divide-and-conquer game model, where individuals can interact with their neighbors in the network with appropriate strategies. We test and compare a series of highly rational strategy updating rules. In the tested scenarios, our analytical and simulation results surprisingly reveal that the less-connected individuals in degree-heterogeneous networks are more likely to become the unfavorable individuals. Our finding suggests that the connectivity of individuals as a social capital fundamentally changes the gaming environment. Our model, therefore, provides a theoretical framework for further understanding the social gaming networks.

The significance, mechanisms and consequences of coronary microvascular dysfunction associated with diabetes mellitus are topics into which we have insufficient insight at this time. It is widely recognized that endothelial dysfunction that is caused by diabetes in various vascular beds contributes to a wide range of complications and exerts unfavorable effects on microcirculatory regulation. The coronary microcirculation is precisely regulated through a number of interconnected physiological processes with the purpose of matching local blood flow to myocardial metabolic demands. Dysregulation of this network might contribute to varying degrees of pathological consequences. This review discusses the most important findings regarding coronary microvascular dysfunction in diabetes from pre-clinical and clinical perspectives. PMID:28643578

Experimental tuberculous lesions were produced by a separate inoculation of Mycobacterium tuberculosis var. bovis and var. hominis in the subcutaineous tissue of the rabbit's back. Then a single x-ray dose of 1,000 r or an injection of streptomycin was administered. The course of these lesions was examined macroscopically and microscopically. When irradiated, repair of the lesions was poor, with thickened outer membranous layer and increased cell infiltration. Bilateral irradiation had a more unfavorable effect than single irradiation. The group treated with streptomycin had a better outcome. (Abstr. Japan. Med., 1: No. 1, 1960)

Cancer mortality rates for all sites are nearly 2.5 times greater for African-Americans compared with whites. In addition, there are data implying that cancer treatment outcomes for minorities are unfavorable compared with whites. Whether this is due to poor access to health care or a biologic property of malignancies occurring in specific populations remains to be determined. Because of these unknown factors, targeting minorities for clinical trials may contribute toward the reduction of the overall morbidity and mortality associated with specific cancers. The current study describes the establishment of a genuine collaborative partnership between the targeted minority community and clinical investigators at the University of Alabama at Birmingham. This partnership was formed for the purpose of identifying strategies that would enhance the accrual and retention of minority participants into current and future cancer prevention and control trials. Focus groups and key informant interviews were conducted to ascertain the community's perception of participating in clinical trials. The majority of focus group participants were unclear regarding the nature of clinical trials. Participants indicated that they would participate in research studies if they received adequate information regarding the purpose and benefits of the study, and if the charge came from a pastor or physician. Barriers to participation included time commitments, family obligations, whether blood was involved, and past experiences. The majority of the participants indicated that their knowledge of the Tuskegee Syphilis Study did not influence their decision to participate in research. A major outcome of the conference was the formation of the Statewide Tuskegee Alliance Coalition. The planning coalition decided to continue their efforts to work with communities and promote cancer awareness among minorities. After the conference, the coalition conducted several meetings and in July 1998, 1 year after the conference, the coalition selected a chair, co-chair, and a formal name for the organized group. The planning, development, and implementation of this conference provided a valuable experience for researchers and community members. It was discovered that community involvement in the early phase of this project contributed to its success. Furthermore, the partnership that developed between researchers (academic institutions) and communities successfully provided an infrastructure that supported the interest of both groups.

Saber, Aly

2014-05-01

Numerous surgical procedures have been described for pilonidal sinus disease, but treatment failure and disease recurrence are frequent. Conventional off-midline flap closures have relatively favorable surgical outcomes, but relatively unfavorable cosmetic outcomes. The author reported outcomes of a new simplified off-midline technique for closure of the defect after complete excision of the sinus tracts. Two hundred patients of both sexes were enrolled for modified D-shaped excisions were used to include all sinuses and their ramifications, with a simplified procedure to close the defect. The overall wound infection rate was 12%, (12.2% for males and 11.1% for females). Wound disruption was necessitating laying the whole wound open and management as open technique. The overall wound disruption rate was 6%, (6.1% for males and 5.5% for females) and the overall recurrence rate was 7%. Our simplified off-midline closure without flap appeared to be comparable to conventional off-midline closure with flap, in terms of wound infection, wound dehiscence, and recurrence. Advantages of the simplified procedure include potentially reduced surgery complexity, reduced surgery time, and improved cosmetic outcome.

The purpose of this study was to investigate whether quantitative assessment of cytologic anaplasia and angiogenesis may predict the clinical prognosis in medulloblastoma and stratify the patients to avoid both undertreatment and overtreatment. Medulloblastomas from 23 patients belonging to the Pediatric Oncology Group were evaluated with respect to some prognostic variables, including histologic assessment of nodularity and desmoplasia, grading of anaplasia, measurement of nuclear size, mitotic cell count, quantification of angiogenesis, including vascular surface density (VSD) and microvessel number (NVES), and immunohistochemical scoring of vascular endothelial growth factor (VEGF) expression. Univariate and multivariate analyses for prognostic indicators for survival were performed. Univariate analysis revealed that extensive nodularity was a significant favorable prognostic factor, whereas the presence of anaplasia, increased nuclear size, mitotic rate, VSD, and NVES were significant unfavorable prognostic factors. Using multivariate analysis, increased nuclear size was found to be an independent unfavorable prognostic factor for survival. Neither the presence of desmoplasia nor VEGF expression was significantly related to patient survival. Although care must be taken not to overstate the importance of the results of this single-institution preliminary report, pathologic grading of medulloblastomas with respect to grading of anaplasia and quantification of nodularity, nuclear size, and microvessel profiles may be clinically useful for the treatment of medulloblastomas. Further validation of the independent prognostic significance of nuclear size in stratifying patients is required.

Introduction: To date, many prognostic models have been proposed to predict the outcome of patients with traumatic brain injuries. External validation of these models in different populations is of great importance for their generalization. The present study was designed, aiming to determine the value of CRASH prognostic model in prediction of 14-day mortality (14-DM) and 6-month unfavorable outcome (6-MUO) of patients with traumatic brain injury. Methods: In the present prospective diagnostic test study, calibration and discrimination of CRASH model were evaluated in head trauma patients referred to the emergency department. Variables required for calculating CRASH expected risks (ER), and observed 14-DM and 6-MUO were gathered. Then ER of 14-DM and 6-MUO were calculated. The patients were followed for 6 months and their 14-DM and 6-MUO were recorded. Finally, the correlation of CRASH ER and the observed outcome of the patients was evaluated. The data were analyzed using STATA version 11.0. Results: In this study, 323 patients with the mean age of 34.0 ± 19.4 years were evaluated (87.3% male). Calibration of the basic and CT models in prediction of 14-day and 6-month outcome were in the desirable range (P < 0.05). Area under the curve in the basic model for prediction of 14-DM and 6-MUO were 0.92 (95% CI: 0.89-0.96) and 0.92 (95% CI: 0.90-0.95), respectively. In addition, area under the curve in the CT model for prediction of 14-DM and 6-MUO were 0.93 (95% CI: 0.91-0.97) and 0.93 (95% CI: 0.91-0.96), respectively. There was no significant difference between the discriminations of the two models in prediction of 14-DM (p = 0.11) and 6-MUO (p = 0.1). Conclusion: The results of the present study showed that CRASH prediction model has proper discrimination and calibration in predicting 14-DM and 6-MUO of head trauma patients. Since there was no difference between the values of the basic and CT models, using the basic model is recommended to simplify the risk calculations. PMID:27800540

When executed properly, open structure rhinoplasty can dramatically improve the consistency, durability, and quality of the cosmetic surgical outcome. Moreover, in expert hands, dramatic transformations in skeletal architecture can be accomplished with minimal risk and unparalleled control, all while preserving nasal airway function. While skeletal enhancements have become increasingly more controlled and precise, the outer skin-soft tissue envelope (SSTE) often presents a formidable obstacle to a satisfactory cosmetic result. In noses with unusually thick skin, excessive skin volume and characteristically hostile healing responses frequently combine to obscure or sometimes even negate cosmetic skeletal modifications and taint the surgical outcome. For this challenging patient subgroup, care must be taken to optimize the SSTE using a graduated treatment strategy directed at minimizing skin thickness and controlling unfavorable healing responses. When appropriate efforts are implemented to manage thick nasal skin, cosmetic outcomes are often substantially improved, sometimes even negating the ill-effects of thick skin altogether.

The role of immune system is the maintenace of the integritiy of the living organism. The elements of the immune system are connected by several ways forming a complex biological network. This network senses the changes of the inner and outer environment and works out the most effective response against infections and tumors. Dysfunction of the immune system leads to the development of cancer development and chronic inflammatory diseases. Modulation of the checkpoints of the immune system opened new perspecitves in the treatment of rheumatological and oncological diseases as well. Beside the potent antiinflammatory activity, new therapies are able to stimulate anticancer activity of the immune system. The result of these recent developments is a better outcome of malignant diseases, which had an unfavorable outcome in the past. Orv. Hetil., 2016, 157(Suppl. 2), 3-8.

Objective: To assess the real importance of obtaining informed consent, through an appropriate form, and its role in the outcome from civil liability claims. Methods: The wordings of the current Brazilian law and jurisprudence were compared with rulings from the State Court of the State of Rio de Janeiro, in 269 civil liability claims against healthcare professionals and hospitals. Results: Favorable and unfavorable outcomes (i.e. acquittals and convictions) were compared, and possible variations in the verdicts were discussed in relation to whether informed consent forms had been filled out or not. Conclusions: Obtaining informed consent, by means of appropriate forms, is still not a widespread practice in the Brazilian healthcare or judicial systems. It is recommended that this practice be adopted in the manner described in this paper, since this is prescribed in Brazilian law. PMID:27022541

We investigated whether greed would predict risky decision-making and recorded neural responses during a monetary gambling task using the electroencephalogram. We found that individuals high in trait-greed took higher risks to maximize monetary outcome. Furthermore, this relation was moderated by state-greed; specifically, trait-greed had a stronger impact on risky decision-making when activated by situational characteristics. On the neural level, greedy individuals showed a specific response to favorable and unfavorable outcomes. Specifically, they had a reduced feedback-related negativity-difference score to these events, indicating that they might have difficulty in learning from experience, especially from mistakes and negative feedback. It is concluded that greed may explain risky and reckless behavior in diverse settings, such as investment banking, and may account for phenomena such as stock market bubbles.

The importance of lifestyle and dietary habits during pregnancy and breastfeeding, for health of mothers and their offspring, is widely supported by the most recent scientific literature. The consumption of a varied and balanced diet from the preconceptional period is essential to ensure both maternal well-being and pregnancy outcomes. However, the risk of inadequate intakes of specific micronutrients in pregnancy and lactation is high even in the most industrialized countries. This particularly applies to docosahexaenoic acid (DHA), iron, iodine, calcium, folic acid, and vitamin D, also in the Italian population. Moreover, the risk of not reaching the adequate nutrient supply is increased for selected groups of women of childbearing age: those following exclusion diets, underweight or overweight/obese, smokers, adolescents, mothers who have had multiple or close pregnancies, and those with previous unfavorable pregnancy outcomes.

Perioperative nurses are likely to encounter the use of pneumatic tourniquets in a variety of operative and invasive extremity procedures. Use of a pneumatic tourniquet offers an opportunity to obtain a near-bloodless surgical field; however, the use of tourniquets is not without risk. Unfavorable outcomes include pain, thrombotic events, nerve compression injuries, and disruption of skin integrity. Perioperative nurses should be familiar with the indications, contraindications, and changes in physiology associated with pneumatic tourniquet use. The revised AORN "Recommended practices for care of patients undergoing pneumatic tourniquet-assisted procedures" is focused on the perioperative nurse's role in patient care and provides guidance for developing, implementing, and evaluating practices that promote patient safety and improve the likelihood of positive outcomes.

Assessment of treatment outcome is the only non-invasive approach to identify the effects of cleft lip and palate repair and modify management accordingly. Here the aim is to assess the outcome of complete unilateral cleft lip and palate (CUCLP) patients using EUROCRAN index and to check whether there are any factors associated with the treatment outcome. It is a retrospective cross sectional study. Dental models were collected from archives of two cleft referral centers in Pakistan. Five blinded examiners scored 101 models twice at two week interval. The primary outcome was mean EUROCRAN scores based on dental arch relationships and palatal surface morphology. A mean(SD) score of 2.72 (0.76) and 2.20 (0.73) was determined based on dental arch relationships and palatal surface morphology, respectively. According to the final logistic regression model, modified Millard technique (cheiloplasty) and Veau-Wardill-Kilners' method (palatoplasty) had higher odds of producing unfavorable treatment outcome. Present study determined a fair and a fair to poor treatment outcome based on dental arch relationships and palatal surface morphology, respectively. Our study suggests a significant association between treatment outcome and primary surgical techniques for lip and palate. These findings could warrant a modification of management protocols to ensure improvement in future cleft outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

In observational studies, a high body temperature has been associated with unfavorable outcome. In in vitro studies, the fibrinolytic activity of alteplase decreased 5% per degree Celsius reduction in temperature. The modifying effect of body temperature on treatment with alteplase in patients with acute ischemic stroke is unclear. We assessed the influence of baseline body temperature on the effect of alteplase on functional outcome in patients with acute ischemic stroke, included in the Paracetamol (Acetaminophen) in Stroke (PAIS) trial. PAIS was a randomized, double-blind clinical trial to assess the effect of high-dose paracetamol on functional outcome in patients with acute stroke. For this study, we selected all patients with ischemic stroke and randomization within 6 h of symptom onset. We estimated the effect of treatment with alteplase on the modified Rankin Scale score at 3 months with ordinal logistic regression, stratified by baseline body temperature. We made adjustments for confounding factors and expressed associations as adjusted odds ratios (aOR) with 95% confidence intervals (CI). We also tested for interaction between treatment with alteplase and body temperature. We included 647 of the 1,400 patients in PAIS in our study. Treatment with alteplase was associated with improved functional outcome at 3 months (aOR 1.51, 95% CI 1.09-2.08). In the 286 patients (44%) with a baseline body temperature of 37.0°C or higher, alteplase was associated with a larger effect (aOR 2.13, 95% CI 1.28-3.45) than in patients with a temperature below 37.0°C (aOR 1.11, 95% CI 0.71-1.69). A test for interaction between body temperature and alteplase did not reach statistical significance (p = 0.18). Patients with ischemic stroke and a high body temperature may have a larger benefit of treatment with alteplase than patients with lower body temperatures. These findings are in line with those from in vitro studies, in which lowering temperature decreased the fibrinolytic activity of the enzyme alteplase. This interaction should be explored further in randomized clinical trials of thrombolytic therapy or modification of body temperature. Trials of therapeutic hypothermia should be controlled for treatment with thrombolytics, and trials of thrombolytic treatment should consider body temperature as a potential effect modifier.

The failure of primary endodontic treatment is manifested by various clinical symptoms following endodontic therapy or, more frequently, by the development of chronic inflammatory process in the apex region without any subjective symptoms. In case of unfavorable outcome of the primary endodontic treatment, orthograde endodontic retreatment is the method of choice for a prolonged therapy. Two female patients, 47 and 44 years old, were presented at the Dental Clinic of Vojvodina for endodontic retreatment of teeth 22, 23 and 13, within the repeated prosthetic restoration. Intraradicular individual cast posts were removed using ultrasonic instruments. Remains of gutta-percha were removed by engine driven rotary re-treatment files, root canals were shaped and cleaned using the crown-down technique, and obturated with gutta-percha and epoxy-resin-based sealer using the lateral compaction technique. When there are metal posts or broken instruments in the root canal, the use of ultrasonic instruments is considered a safe method characterized by negligible tooth substance loss and minimal root damage causing fractures and perforations, and the entire procedure is effective and predictable. Non-surgical orthograde endodontic retreatment, when properly performed in accessible and penetrable root canals, achieves a high cure rate, good and lasting results and eliminates the need for radical procedures, such as apical surgery or tooth extraction. When nonsurgical endodontic retreatment is done, treated teeth must be restored by full coronal coverage as soon as possible, to prevent coronal leakage or fracture.

The introduction of the Woven Endobridge (WEB) device increases the feasibility of endovascular treatment of wide-neck bifurcation aneurysms with limitations given by currently available sizes and shapes of the device. Parallel to other studies, we used the new device for selected patients who were no optimal candidates for established techniques like neurosurgical clipping or endovascular coiling. We aimed to report the angiographic and clinical results of WEB implantations or combinations between WEB and coiling or intracranial stents. We reviewed the records of n = 23 interventions in 22 patients with unruptured wide-neck aneurysms (UIA) who were assigned for aneurysm treatment with the use of the WEB or adjunctive techniques. Interventional procedures and clinical and angiographic outcomes are reported for the periprocedural phase and in mid-term FU. Of the included 22 patients, six patients needed additional coiling, intracranial stenting, or implantation of a flow diverter. WEB implantation was technically feasible in 22 out of the 23 interventions. Follow-up angiographic imaging proved total or subtotal occlusion of the aneurysm in 19 of 22 cases. Two minor recurrences remained stable during a period of 15 months. One patient with a partially thrombosed giant MCA aneurysm had a major recurrence and was retreated with a second WEB in combination with coiling. Despite of unfavorable anatomic conditions, broad-based and large UIA endovascular treatment with the WEB and adjunctive techniques was feasible with a low risk of complications and promising occlusion rates in mid-term follow-up.

Background There is controversy in medical literature over the outcome of patients with lupus nephritis (LN) class II. The aim of this study was to explore the risk of histological transformation (HT) and possible factors related to negative response to treatment in patients with mesangial LN class II. Methods A retrospective and multicenter study was carried out that includes patients who had received a diagnosis of LN class II on their first renal biopsy. Creatinine, urine sediment, and proteinuria were recorded at the time of the first biopsy, 6 months, and 1, 2, and 5 years after the first biopsy. Response to treatment, HT, and long-term outcome were evaluated. Results Forty-one patients were included. The manifestation at first biopsy was proteinuria greater than 0.5 g/d in 28 patients (68.29%; 8 [28.57%] of 28 patients had nephrotic syndrome), hematuria in 18 patients (43.90%), and deterioration of renal function in 3 patients (7.31%). During the follow-up (median, 8 years; range, 1–35 years), a new biopsy was performed in 18 patients (43.90%), and in 17 patients (17/18 [94.44%]), there was HT. Median time at rebiopsy was 32 months (range, 11–305 months). Of the 18 patients who had a second biopsy, 10 (55.55%) were on hydroxychloroquine versus 100% (19/19) of patients who did not undergo the procedure (P = 0.001). A year after the first renal biopsy, there are data available from 34 patients; of them, 24 patients (70.58%) had achieved response, and 10 patients (29.41%) had no response (NR) (missing data in 7). A higher 24-hour urinary protein at 6 months was predictor of worse outcome at 1 year, with statistical significance difference for the nonresponder group (median proteinuria, 2.3 g/d [range, 0–4.7 g/d]) compared with responders (median proteinuria, 0.28 g/d [range, 0–1.7 g/d]) (P = 0.0133). In the long-term follow-up (5 years), HT was the main cause of unfavorable outcome and was measured in 78.57% of patients (11/14 patients). Conclusions This series shows a high rate of HT in long-term follow-up. Proteinuria at 6 months made it possible to set aside patients who will have an unfavorable outcome in the long term and who will thus benefit from a more aggressive treatment. The results suggest that hydroxychloroquine had a nephroprotective effect. PMID:27152693

Two types of lacunar infarcts: further arguments from a study on prognosis.

Earlier, we found that lacunar stroke patients with > or =1 asymptomatic lacunar infarcts on CT had leukoaraiosis and hypertension significantly more often than patients without such lesions, and we hypothesized that 2 types of small-vessel disease could be distinguished during life: arteriolosclerosis and microatheromatosis, respectively. Differences in prognosis might sustain this hypothesis of 2 lacunar stroke entities. Therefore, we performed a follow-up in 333 patients with first lacunar stroke, distinguishing those with > or =1 asymptomatic lacunar lesions (LACI+) from those without such lesions (LACI-). Cross-sectional follow-up was performed after 785+/-479 days (mean+/-SD) in 104 LACI+ patients and 865+/-545 days in 229 LACI- patients. Mortality at the end of follow-up was 33% in LACI+ and 21% in LACI- patients [odds ratio (OR), 1.74; 95% confidence interval (CI), 1.01 to 3.01]. Stroke recurrence rate was 21% in LACI+ and 11% in LACI- (OR, 2.09; 95% CI, 1.08 to 4.06). Forty percent of LACI+ and 26% of LACI- patients had unfavorable outcome at the end of follow-up (OR, 1.95; 95% CI, 1.17 to 3.26). Kaplan-Meier curves showed less favorable survival in LACI+ (log-rank test, P=0.0218) and survival free of stroke (log-rank test, P=0.0121) than in LACI-. When we restricted the analysis to patients with both silent lesions and leukoaraiosis (n=63) compared with those without (n=196), differences were even more pronounced. Prognosis for mortality, recurrent stroke, and overall functional outcome in lacunar stroke patients with > or =1 silent lacunar lesions is more unfavorable than in patients without such lesions. These findings sustain the idea of 2 lacunar stroke entities.
