An accurate diagnosis of amyloidosis and its subtype classification are essential for disease prognostication and treatment. In primary amyloidosis, overall median survival is approximately 2 years and may be less in patients with cardiomyopathy. Current therapy for primary amyloidosis is suboptimal. Controlled studies suggest that treatment with melphalan and prednisone may provide marginal survival benefit. A more aggressive approach such as autologous hematopoietic stem cell transplantation may offer potential for long-term benefit. Although patients undergoing autologous hematopoietic stem cell transplantation are highly selected, response rates can approach 60%, and patients with amyloidosis who respond to treatment have potential for long-term survival. New treatment modalities that were shown to have antitumor activity in multiple myeloma (high-dose dexamethasone and thalidomide) may also be of therapeutic value in primary amyloidosis. Systemic chemotherapy would not be expected to have any beneficial effect on other forms of amyloid and carries significant risk.

To study the effect of red blood cell (RBC) storage duration on long-term mortality in patients undergoing cardiac intervention. RBCs undergo numerous structural and functional changes during storage. Observational studies have assessed the association between RBC storage duration and patient outcomes with conflicting results. Between January 2006 and December 2014, 82 408 patients underwent coronary angiography. Of these, 1856 patients received one to four RBC units within 30 days after this procedure. Patients were allocated according to length of RBC storage duration: short-term (≤11 days), intermediate (IM)-term (12-23 days) and long-term (≥24 days). The study endpoints were 30-day and long-term all-cause mortality. A total of 4168 RBC units were given to 1856 patients. The mean RBC storage duration was 8.5 ± 2.1, 17.7 ± 3.4 and 29.9 ± 3.4 days in the short-term, IM-term and long-term storage groups, respectively. There was no difference in baseline characteristics between the groups. The long-term storage group received significantly more units (2.4 ± 1.0 units) as compared to the short-term (2.0 ± 1.0 units; P < 0.001) and IM-term storage group (2.2 ± 1.0 units; P < 0.01). In the survival analysis, there was no significant difference in all-cause mortality between the groups (log-rank: 0.509 for 30-days mortality; 0.493 for 5-year mortality). Additional stratified analysis demonstrated no association between RBC storage duration and long-term mortality. This study did not find an association between RBC storage duration and 30-days or long-term mortality in patients undergoing cardiac intervention. © 2017 British Blood Transfusion Society.

To compare survival and complications in horses undergoing large colon resection with either sutured end-to-end or stapled functional end-to-end anastomoses. Retrospective cohort study. Twenty-six client-owned horses with gastrointestinal disease. Retrospective data were retrieved from the medical records of 26 horses undergoing colectomy, including 14 horses with sutured end-to-end and 12 horses with stapled functional end-to-end anastomoses, between 2003 and 2016. Records were evaluated for signalment, medical and surgical treatments, and survival to hospital discharge. Long-term follow-up was obtained through owner contact. Continuous variables were compared with Mann-Whitney tests. Fisher's exact testing was used to compare survival to hospital discharge. Survival time was compared by constructing Kaplan-Meier survival curves and performing log-rank curve comparison testing. Mean age of horses undergoing colectomy was 13 years. Reason for colectomy was prophylaxis (12) or salvage (14). Mean surgical time was 169 minutes. Mean hospitalization time was 9 days, which did not differ with anastomosis type (P = .62). Nine of 12 horses undergoing stapled functional end-to-end anastomosis and 12 of 14 horses undergoing sutured end-to-end anastomosis survived to hospital discharge (P = .63). Survival time did not differ with anastomosis technique (P = .35). Short- and long-term survival outcomes are not different between sutured end-to-end or stapled functional end-to-end anastomoses in horses undergoing colectomy. © 2017 The American College of Veterinary Surgeons.

The primary objective was to determine whether children and their participating parents undergoing family-based behavioral treatment (FBT) for obesity show similar dietary changes following treatment, and if so, whether these shared dietary changes explain the similarity in weight change within the parent-child dyad. Data come from a randomized controlled trial of 148 parent-child dyads who completed FBT and were followed over a 2-year maintenance phase. Energy-dense, nutrient-poor foods ("RED" foods) and fruit and vegetable intake were assessed across time. Maintenance of lower RED food intake following FBT predicted weight maintenance in children and in parents (ps < .01), and dietary and weight changes were correlated within parent-child dyads (ps < .01). Most interesting, the similarity in long-term weight maintenance between children and their parents was predicted by the similarity in long-term changes in RED food intake between children and their parents (p < .001). These findings point to the important role of maintaining low energy-dense, nutrient-poor food intake for long-term weight maintenance in children and parents. Furthermore, these results suggest that the correlation between parent and child weight maintenance can be explained in part by similar long-term changes in energy-dense, nutrient-poor food intake.

Development of a cell-based treatment for long-term neurotrophin expression and spiral ganglion neuron survival.

2014-09-26

Spiral ganglion neurons (SGNs), the target cells of the cochlear implant, undergo gradual degeneration following loss of the sensory epithelium in deafness. The preservation of a viable population of SGNs in deafness can be achieved in animal models with exogenous application of neurotrophins such as brain-derived neurotrophic factor (BDNF) and neurotrophin-3. For translation into clinical application, a suitable delivery strategy that provides ongoing neurotrophic support and promotes long-term SGN survival is required. Cell-based neurotrophin treatment has the potential to meet the specific requirements for clinical application, and we have previously reported that Schwann cells genetically modified to express BDNF can support SGN survival in deafness for 4 weeks. This study aimed to investigate various parameters important for the development of a long-term cell-based neurotrophin treatment to support SGN survival. Specifically, we investigated different (i) cell types, (ii) gene transfer methods and (iii) neurotrophins, in order to determine which variables may provide long-term neurotrophin expression and which, therefore, may be the most effective for supporting long-term SGN survival in vivo. We found that fibroblasts that were nucleofected to express BDNF provided the most sustained neurotrophin expression, with ongoing BDNF expression for at least 30 weeks. In addition, the secreted neurotrophin was biologically active and elicited survival effects on SGNs in vitro. Nucleofected fibroblasts may therefore represent a method for safe, long-term delivery of neurotrophins to the deafened cochlea to support SGN survival in deafness. Copyright © 2014 IBRO.

The evolving role of physical therapists in the long-term management of chronic low back pain: longitudinal care using assisted self-management strategies

PubMed Central

Beattie, Paul F.; Silfies, Sheri P.; Jordon, Max

2016-01-01

ABSTRACT Background Longitudinal studies have shown that the symptoms of chronic low back pain (CLBP) will follow an episodic trajectory characterized by periods of high and low pain intensity that can persist for many years. There is a growing belief that the contemporary approach of limiting physical therapy to short, but intense courses of treatment for (CLBP) may be sub-optimal because these limited “windows” of clinical care are not congruent with the natural history of this condition. Recent research has suggested that people with CLBP undergo substantial, and individualized long-term variations in the neural processing of nociception over time. This has led to the concept of a “unique biosignature of pain” that may explain much of the variation in a person’s clinical picture. These and other findings have led to the reconceptualization of CLBP as an individualized, and continually evolving condition that may be more suitably managed by empowering the patient toward self-management strategies that can be modified as needed over time by the PT. Objectives The purpose of this Master Class Paper is to describe an emerging approach for the treatment of CLBP that emphasizes the formation of a long-term therapeutic alliance between the patient and the PT with an emphasis on individualized, patient-preferred approaches for activity-based self-management as an alternative to the contemporary approach of short, intense episodes of care directed toward pain reduction. Conclusion Longitudinal care using assisted self-management strategies is more congruent with the natural history of CLBP than are traditional approaches for PT intervention. This approach may empower patients to undergo lifestyle changes that will favorably influence long-term outcomes; however additional research is needed. PMID:28001268

Treatment for spasmodic dysphonia: limitations of current approaches

PubMed Central

Ludlow, Christy L.

2009-01-01

Purpose of review Although botulinum toxin injection is the gold standard for treatment of spasmodic dysphonia, surgical approaches aimed at providing long-term symptom control have been advancing over recent years. Recent findings When surgical approaches provide greater long-term benefits to symptom control, they also increase the initial period of side effects of breathiness and swallowing difficulties. However, recent analyses of quality-of-life questionnaires in patients undergoing regular injections of botulinum toxin demonstrate that a large proportion of patients have limited relief for relatively short periods due to early breathiness and loss-of-benefit before reinjection. Summary Most medical and surgical approaches to the treatment of spasmodic dysphonia have been aimed at denervation of the laryngeal muscles to block symptom expression in the voice, and have both adverse effects as well as treatment benefits. Research is needed to identify the central neuropathophysiology responsible for the laryngeal muscle spasms in order target treatment towards the central neurological abnormality responsible for producing symptoms.

The optimal type of surgical management for isolated sagittal synostosis remains a source of significant debate. There is a paucity of data regarding possible differences in long-term neuropsychological outcomes following treatment with whole-vault cranioplasty or endoscopic strip craniectomy. This study provides the first comparative analysis examining the effects of the two techniques related to long-term intellectual functioning. A total of 70 patients were enrolled in this multicenter study, 29 of whom had previously undergone endoscopic strip craniectomy and 41 of whom had previously undergone whole-vault cranioplasty. All patients completed a battery of neurodevelopmental tests (Beery-Buktenica Developmental Test of Visual-Motor Integration, Wechsler Abbreviated Scale of Intelligence, and Wechsler Fundamentals) to evaluate various domains of neuropsychological function. In a group comparison of those treated before 6 months of age, whole-vault patients obtained higher scores relative to endoscopic strip craniectomy patients on visuomotor integration, full-scale intelligence quotient, verbal intelligence quotient, word reading, and reading comprehension (p < 0.05 for all). When compared against strip craniectomy performed before 3 months of age, the whole-vault group still showed significantly higher scores in verbal intelligence quotient, reading comprehension, and word reading (p < 0.05 for all). The type of surgical intervention for isolated sagittal synostosis impacts long-term neuropsychological outcomes. Patients undergoing early whole-vault cranioplasty attained higher intelligence quotient and achievement scores relative to those undergoing strip craniectomy. Surgical management with whole-vault cranioplasty performed before 6 months of age provides the most favorable long-term intellectual outcomes in patients with isolated sagittal synostosis.

1977-01-01

Minoxidil, a new potent hypotensive agent, was used as the primary antihypertensive agent in 11 patients--10 men and 1 woman aged 35 to 54 years with severe hypertension that was refractory to treatment with maximal (or maximally tolerated) doses of conventional antihypertensive agents. Six patients had severely impaired renal function and three of them were undergoing long-term hemodialysis. The patients were given 2.5 to 40 mg/d of minoxidil for periods of 2 to 29 months. All except one who was almost anuric received propranolol and diuretics. Blood pressure was controlled satisfactorily in all patients. In two patients the hypertension became partially resistant after 1 year of treatment. The main side effects were sodium retention, tachycardia and hirsutism. Renal function remained stable or improved and hemodialysis was discontinued in two patients. Minoxidil is a remarkably potent hypotensive with relatively few side effects and seems particularly advantageous in patients with chronic renal failure. PMID:603847

Does intraoperative facial nerve monitoring during vestibular schwannoma surgery lead to better long-term facial nerve function? This recommendation applies to adult patients undergoing vestibular schwannoma surgery regardless of tumor characteristics. Level 3: It is recommended that intraoperative facial nerve monitoring be routinely utilized during vestibular schwannoma surgery to improve long-term facial nerve function. Can intraoperative facial nerve monitoring be used to accurately predict favorable long-term facial nerve function after vestibular schwannoma surgery? This recommendation applies to adult patients undergoing vestibular schwannoma surgery. Level 3: Intraoperative facial nerve can be used to accurately predict favorable long-term facial nerve function after vestibular schwannoma surgery. Specifically, the presence of favorable testing reliably portends a good long-term facial nerve outcome. However, the absence of favorable testing in the setting of an anatomically intact facial nerve does not reliably predict poor long-term function and therefore cannot be used to direct decision-making regarding the need for early reinnervation procedures. Does an anatomically intact facial nerve with poor electromyogram (EMG) electrical responses during intraoperative testing reliably predict poor long-term facial nerve function? This recommendation applies to adult patients undergoing vestibular schwannoma surgery. Level 3: Poor intraoperative EMG electrical response of the facial nerve should not be used as a reliable predictor of poor long-term facial nerve function. Should intraoperative eighth cranial nerve monitoring be used during vestibular schwannoma surgery? This recommendation applies to adult patients undergoing vestibular schwannoma surgery with measurable preoperative hearing levels and tumors smaller than 1.5 cm. Level 3: Intraoperative eighth cranial nerve monitoring should be used during vestibular schwannoma surgery when hearing preservation is attempted. Is direct monitoring of the eighth cranial nerve superior to the use of far-field auditory brain stem responses? This recommendation applies to adult patients undergoing vestibular schwannoma surgery with measurable preoperative hearing levels and tumors smaller than 1.5 cm. Level 3: There is insufficient evidence to make a definitive recommendation.  The full guideline can be found at: https://www.cns.org/guidelines/guidelines-manage-ment-patients-vestibular-schwannoma/chapter_4.

The risk factors associated to long-term survival were assessed in patients with liver metastases of colorectal carcinoma undergoing ablative therapies. Single-centre cohort study, retrospectively analysed and prospectively collected consecutive patients with unresectable metastatic liver disease of colorectal carcinoma treated with ablative therapies between 1996 and 2013. Factors associated with survival time were identified using Cox's proportional hazard model with time-dependent covariates. A forward variable selection based on Akaike information criterion was performed. Relative risk and 95% confidence intervals for each factor were calculated. Statistical significance was set as P<.05. Seventy-five patients with liver metastases of colorectal cancer, with a mean age of 65.6 (10.3) underwent 106 treatments. Variables selected were good quality of life (RR 0.308, 95% CI 0.150-0.632) and tumour extension (RR 3.070, 95% CI 1.776-5.308). The median overall survival was 18.5 months (95% CI 17.4-24.4). The survival prognosis in median was 13.5 vs. 23.4 months for patients with and without tumour extension, and 23.0 vs. 12.8 months for patients with good and fair or poor quality of life, respectively. Good quality of life and tumour extension were the only statistically significant predictors of long-term survival in patients of colorectal carcinoma with liver metastatic disease undergoing ablative treatment with ultrasound.

The optimal duration of systemic antibiotic therapy in patients with prosthetic hip infection (PHI) undergoing staged exchange arthroplasty (SEA) has not been determined. We hypothesized that with an antibiotic-loaded cement spacer (ALCS), in the interim, short-term antibiotic therapy is as effective as a conventional prolonged treatment course. We reviewed 99 patients with PHI who were managed with SEA using an ALCS from February 2002 to October 2005. A standard (4-6 week) antibiotic treatment course was administered in the first 46 patients and a short-term (1 week) therapy was adopted in the subsequent 53 patients. Eight patients (four in each group) had persistent infection following the first attempt of surgery and antibiotic treatment; in three of them the infection was cured by additional debridement prior to re-implantation. Forty-two (91%) patients in the long-term group and 47 (89%) patients in the short-term group were free of infection (P = 0.67) at an average follow-up of 43 months (range, 24-60 months). Five (11%) patients developed complications related to prolonged antibiotic therapy. The short-term treatment resulted in a shorter hospital stay (18 versus 43 days, P < 0.001) and a lower direct medical cost (US$13 732 versus US$21 756, P < 0.001). Short-term antibiotic therapy was not associated with a higher rate of treatment failure. Given the higher costs and incidence of complications, protracted courses of antibiotic administration may not necessarily be routine practice in patients with PHI undergoing SEA, provided that an ALCS is used.

We and others have previously shown that testosterone replacement therapy (TRT) results in sustained weight loss in the majority of middle-aged hypogonadal men. Previously, however, a small proportion failed to lose at least 5% of their baseline weight. The reason for this is not yet understood. In the present study, we sought to identify early indicators that may predict successful long-term weight loss, defined as a reduction of at least 5% of total body weight relative to baseline weight (T0), in men with hypogonadism undergoing TRT. Eight parameters measured were assessed as potential predictors of sustained weight loss: loss of 3% or more of baseline weight after 1 year of TU treatment, severe hypogonadism, BMI, waist circumference, International Prostate Symptom Score (IPSS), glycated hemoglobin (HbA 1C ), age and use of vardenafil. Among the eight measured parameters, three factors were significantly associated with sustained weight loss over the entire period of TU treatment: (1) a loss of 3% of the baseline body weight after 1 year of TRT; (2) baseline BMI over 30; and (3) a waist circumference >102 cm. Age was not a predictor of weight loss.

Few studies have investigated the impact of diabetes mellitus (DM), a globally increasing metabolic disease, on treatment outcomes and long-term survival in patients with multidrug-resistant forms of tuberculosis (MDR-TB). We analyzed outcomes in a large cohort to assess the impact of DM on treatment outcomes of patients with MDR-TB. MDR-TB patients newly diagnosed or retreated between 2000 and 2002 and followed for 8-11 years were retrospectively analyzed with respect to the effect of DM as a comorbidity on their treatment outcome and long-term survival. Of 1,407 patients with MDR-TB, 239 (17.0%) had coexisting DM. The mean age and body mass index were higher in MDR-TB patients with DM [MDR-TBDM(+)] than in those without DM [MDR-TBDM(-)]. Patients with MDR-TB and a comorbidity of DM had a significantly lower treatment success rate than those without a history of DM (36.0 vs. 47.2%, p = 0.002). In addition, DM was the negative predictor for MDR-TB treatment success in multivariate analyses [odds ratio 0.51, 95% confidence interval (CI) 0.26-0.99]. Mean survival times were also lower in MDR-TBDM(+) than in MDR-TBDM(-) patients (102 vs. 114 months, p = 0.001), with DM as a significant predictor of poor long-term survival in multivariate analyses (hazard ratio 1.59, 95% CI 1.01-2.50). Among MDR-TB patients, DM was a relatively common comorbidity. In patients undergoing treatment for MDR-TB and followed for 8-11 years, it was found to be independently associated with an increased risk of both treatment failure and death. Copyright © 2013 S.

A clopidogrel loading dose administered during stenting attenuates inflammation marker release. However, less is known of the anti-inflammatory effect of clopidogrel maintenance therapy. Platelet reactivity to adenosine diphosphate and inflammation markers were measured in 110 consecutive patients (69 clopidogrel-naive patients and 41 patients receiving long-term clopidogrel therapy for >6 months) before nonemergent stenting by turbidimetric aggregometry and flow cytometry and multianalyte profiling, respectively. All patients were treated with aspirin. Prestenting adenosine diphosphate-induced platelet aggregation, P-selectin, and activated glycoprotein IIb/IIIa expression were lower in patients receiving long-term clopidogrel therapy compared with the clopidogrel-naive group (p <0.001), accompanied by lower levels of selected inflammation markers (p < or = 0.05). Additionally, there were strong correlations between platelet aggregation and flow cytometric measurements (p < or = 0.04) and between specific inflammation markers (p < or = 0.02). In conclusion, in addition to markedly lowering platelet reactivity to adenosine diphosphate, long-term clopidogrel therapy is associated with an anti-inflammatory effect.

Endovascular therapy with liquid embolic agents is a common treatment strategy for cranial dural arteriovenous fistulas. This study evaluated the long-term effectiveness of transarterial Onyx as the single embolic agent for curative embolization of noncavernous cranial dural arteriovenous fistulas. We performed a retrospective review of 40 consecutive patients with 41 cranial dural arteriovenous fistulas treated between March 2006 and June 2012 by using transarterial Onyx embolization with intent to cure. The mean age was 57 years; one-third presented with intracranial hemorrhage. Most (85%) had cortical venous drainage. Once angiographic cure was achieved, long-term treatment effectiveness was assessed with DSA and clinical follow-up. Forty-nine embolization sessions were performed; 85% of cranial dural arteriovenous fistulas were treated in a single session. The immediate angiographic cure rate was 95%. The permanent neurologic complication rate was 2% (mild facial palsy). Thirty-five of the 38 patients with initial cure underwent short-term follow-up DSA (median, 4 months). The short-term recurrence rate was only 6% (2/35). All patients with occlusion at short-term DSA undergoing long-term DSA (median, 28 months) had durable occlusion. No patient with long-term clinical follow-up (total, 117 patient-years; median, 45 months) experienced hemorrhage. Transarterial embolization with Onyx as the single embolic agent results in durable long-term cure of noncavernous cranial dural arteriovenous fistulas. Recurrence rates are low on short-term follow-up, and all patients with angiographic occlusion on short-term DSA follow-up have experienced a durable long-term cure. Thus, angiographic cure should be defined at short-term follow-up angiography instead of at the end of the final embolization session. Finally, long-term DSA follow-up may not be necessary if occlusion is demonstrated on short-term angiographic follow-up. © 2014 by American Journal of Neuroradiology.

Aim To prospectively determine the role of platelet glycoprotein IIIa (GP IIIa) gene PlA1/PlA2 polymorphism on the long-term clinical outcome in patients with coronary artery disease undergoing coronary stenting. Design and setting Prospective observational study in the University Hospital of Caen (France). Patients and methods 1 111 symptomatic consecutive Caucasian patients treated with percutaneous coronary intervention including stent implantation underwent genotyping for GP IIIa PlA1/A2. Main outcome measures Long-term clinical outcome in terms of the rate of major adverse cardiac events (MACE, ie death from any cause, non-fatal Q wave or non Q wave myocardial infarction, and need for coronary revascularisation) was obtained and subsequently stratified according to the GP IIIa PlA1/A2 polymorphism. Results Three groups of patients were determined according to the GP IIIa PlA1/A2 polymorphism (71.6% had the A1/A1, 25.8% had the A1/A2 and 2.6% had the A2/A2 genotype). These three groups were comparable for all clinical characteristics including sex ratio, mean age, vascular risk factors, previous coronary events, baseline angiographic exam, indication for the percutaneous coronary intervention and drug therapy). The incidence of MACE was similar in these 3 groups of patients during a mean follow-up period of 654+/-152 days. Independent risk factors for MACE were a left ventricular ejection fraction < 40%, absence of treatment with a beta-blocker and absence of treatment with an angiotensin converting enzyme inhibitor during follow-up. Conclusion The GP IIIa PlA1/A2 polymorphism does not influence the clinical long-term outcome in patients with symptomatic coronary disease undergoing percutaneous coronary intervention with stent implantation.

The experience of 92 couples, who had unsuccessfully undergone one or more IVF cycles at a university clinic, was evaluated 3-8 years following their last failed attempt. One member of each couple completed a telephone questionnaire regarding life events during their last IVF cycle performed at the clinic and at the time of the interview. Some couples had continued further treatment and some had not. Multivariate correspondence analysis was used to analyse the data. Regarding the long-term experience of couples who had undergone further treatment, for men the main experiences were psychological problems and having adopted a child. For women, the main experiences were related to problems of self-image, psychological problems, loss of hope, and having adopted a child. These women also presented a strong association with problems in their marital relationship and with adoption. For the group that did not undergo further treatment, the women showed a strong association with considering adoption, and a less intense association with psychological problems and loss of hope. The men presented psychological problems and having adopted a child as associated variables. Comparison between men and women showed that recognizing the impossibility of conceiving a child and giving up treatment were strongly associated. Men and women who had not continued with further treatment were more affected in the long term than those who had undergone further treatment after IVF failure.

Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). All consecutively treated female patients from two urological institutions who underwent RC and urinary diversion from January 2000 to December 2008, with no evidence of tumor recurrence at a minimum follow up of 36 months, were included. Patients received the European Organisation for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL). Clinical data and questionnaire results were analyzed in order to evaluate the HRQOL differences among diversion groups. We identified 37 females (median age: 68, range 45-82 years), including 12 status-post CUS, 16 who underwent BK-IC, and 9 who underwent ONB-VIP. Most were healthy (24/37 with no comorbidities, 4/37 Charlson 1-2, 9/37 Charlson 3 or greater - we didn't considered bladder cancer in Charlson evaluation because bladder cancer was the main inclusion criteria). Women undergoing CUS endorsed worse FACT-BL scores compared with BK-IC and ONB-VIP patients, worse HRQOL regarding physical and emotional well-being (p=0.008 and p=0.02, respectively), and a trend toward worse EORTC QLQ-C30 scores for appetite loss and fatigue (p=0.05 for both). In our study long-term disease-free females treated with CUS endorsed worse HRQOL compared with women who underwent BK-IC or ONB-VIP, mostly due to worse physical and emotional perception of their body image.

Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long-term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long-term tyrosine kinase inhibitor (TKI) therapy for CML. A 57-year-old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19. Previous medical treatment included oral administration (>10 years) of TKI for the treatment of CML. Systemic complications arising from long-term TKI therapy were treated with discontinuation of this medication. Concurrently, after multispecialty dental and medical consultation, extraction of tooth #19 with immediate implant placement and bilateral sinus augmentation with simultaneous implant placement were successfully performed during three separate surgical appointments. Additionally, marked reduction of oral palatal pigmentation was observed during the surgical and restorative phases after TKI discontinuation. Patients with a history of long-term TKIs for CML are at risk for developing complications that result in discontinuation of therapy. Long-term benefits of therapy may allow these patients to enjoy remission with an extended and improved quality of life. Patients undergoing discontinuation therapy may seek dental care. Therefore, dental providers need to understand these systemic interactions and, with multispecialty consultation, may help effectively treat these individuals.

The purpose of this study was to evaluate the outcomes for elderly (> or =80 years) patients undergoing aortic valve replacement (AVR) with or without coronary artery bypass graft surgery (AVR/CABG). The authors hypothesized that the mortalities of AVR and AVR/CABG are lower than that predicted by published risk scores. A retrospective analysis of data from a single-hospital database. Single tertiary care, private practice. Consecutive patients undergoing AVR or AVR/CABG. Two hundred sixty-one elderly (> or =80 years) patients undergoing isolated AVR (145) or AVR/CABG (116) were evaluated. The majority (94.6%) underwent AVR for aortic valve stenosis. Outcomes were recorded and compared between the 2 surgical procedures with predicted mortalities based on published risk assessment scoring systems. The overall short-term mortality for the elderly group was 6.1% (AVR 5.5% and AVR/CABG 6.9%). The median long-term survival was 6.8 years. There were no significant differences in either morbidity or mortality between the AVR and AVR/CABG groups. Although predicted mortalities were similar for each surgical procedure, they overestimated observed outcome by up to 4-fold. Short- and long-term mortality was low for this group of elderly patients undergoing AVR or AVR/CABG and not significantly different between the 2 surgical groups. Predicted outcomes were worse than that observed, consistent with the hypothesis, and supportive of a more aggressive surgical treatment for aortic valve disease in the elderly patient.

Postoperative face-down posturing (FDP) is recommended to optimize the effects of intraocular gas tamponade after vitrectomy. However, patients undergoing FDP usually experience physical and psychological burdens. This 3-armed, randomized, single-center trial investigated the effects of aromatherapy on FDP-related physical pain. Sixty-three patients under FDP were randomly allocated to one of three treatment groups: aromatherapy massage with essential oil (AT), oil massage without essential oil (OT), and a control group. The AT and OT groups received 10 minutes of massage by ward nurses trained by an aromatherapist, while the control group received usual care. Outcomes were assessed as short-term (pre- to post-intervention) and long-term (first to third postoperative day) changes in physical pain in five body regions using face-scale. The AT and OT groups both revealed similar short-term pain reductions after intervention, compared with the control group. Regarding long-term effects, neither group experienced significant effects until the second day. Significantly more pain reduction compared with usual care occurred on the third day, mainly in the AT group, though there were few significant differences between the AT and OT groups. In conclusion, this study suggests that simple oil massage is an effective strategy for immediate pain reduction in patients undergoing FDP, while aromatherapy may have a long-term effect on pain reduction.

Gamma Knife® radiosurgery for trigeminal neuralgia.

PubMed

Yen, Chun-Po; Schlesinger, David; Sheehan, Jason P

2011-11-01

Trigeminal neuralgia is characterized by a temporary paroxysmal lancinating facial pain in the trigeminal nerve distribution. The prevalence is four to five per 100,000. Local pressure on nerve fibers from vascular loops results in painful afferent discharge from an injured segment of the fifth cranial nerve. Microvascular decompression addresses the underlying pathophysiology of the disease, making this treatment the gold standard for medically refractory trigeminal neuralgia. In patients who cannot tolerate a surgical procedure, those in whom a vascular etiology cannot be identified, or those unwilling to undergo an open surgery, stereotactic radiosurgery is an appropriate alternative. The majority of patients with typical facial pain will achieve relief following radiosurgical treatment. Long-term follow-up for recurrence as well as for radiation-induced complications is required in all patients undergoing stereotactic radiosurgery for trigeminal neuralgia.

OBJECTIVE To describe the technique and short- and long-term outcomes for dogs undergoing double-pigtail ureteral stent placement for treatment of benign ureteral obstruction. DESIGN Retrospective case series. ANIMALS 44 dogs (57 ureters). PROCEDURES Medical records of dogs that underwent ureteral stenting for treatment of benign ureteral obstruction between 2010 and 2013 were reviewed. Signal-ment, history, pertinent diagnostic imaging results, endourologic and post-procedural details, duration of hospitalization, complications, and outcome (short term, 7 to 30 days; long term, > 30 days) were recorded. Ureteral stent placement was performed endoscopically, surgically, or both, with fluoroscopic guidance. RESULTS 57 ureters (44 dogs) underwent stenting because of obstructive ureterolithiasis (n = 48 [84%]), stricture (5 [9%]), or both (4 [7%]). Endoscopic or surgical techniques were successful for stent placement in 45 of 55 and 12 of 12 ureters (34/42 and 10/10 dogs), respectively. Median hospitalization time was 1 day. Median creatinine concentration was 2 mg/dL prior to stenting and 1.3 mg/dL 3 months after the procedure. Urinary tract infections were present in 26 of 44 (59%) dogs prior to stenting and in 11 of 43 dogs (26%) after stenting. One of the 44 (2%) dogs died after undergoing stenting, but the cause of death was not related to the procedure. Median follow-up time was 1,158 days (range, 3 to > 1,555 days), with 30 of 44 dogs alive at the time of last follow-up. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that ureteral stenting may be a viable option for first-line treatment of dogs with benign ureteral obstruction. However, patients should be monitored for urinary tract infection following stenting.

The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well-accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG. We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4. Patients with lower PNI had significantly higher in-hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4). The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG.

Long-term potentiation and long-term depression: a clinical perspective

PubMed Central

Bliss, Timothy V.P.; Cooke, Sam F

2011-01-01

Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke. PMID:21779718

Although quitting motivation predicts smoking cessation, there have been inconsistent findings regarding motivation predicting long-term maintenance of abstinence. Moreover, most such research has been conducted in North America and the United Kingdom. The aim of this study was to examine motivation to quit as a predictor of smoking cessation and of abstinence maintenance in a Spanish sample. The sample comprised 286 Spanish smokers undergoing psychological treatment for smoking cessation. Motivation to quit was assessed pre-treatment and post-treatment with the Readiness to Quit Ladder. Abstinence post-treatment and at 6month follow-up was biochemically verified. Participants with higher levels of pre-treatment and post-treatment motivation were more likely to be abstinent at the end of the treatment (OR=1.36) and at 6month follow-up (OR=4.88). Among abstainers at the end of the treatment (61.9%), higher levels of motivation to quit post-treatment predicted maintaining abstinence at 6months (OR=2.83). Furthermore, participants who failed to quit smoking reported higher levels of motivation to quit post-treatment than they had pretreatment (p<.001). Motivation to quit smoking predicted short and long-term cessation, and also predicted long-term maintenance of abstinence. These results have implications for understanding motivational processes of smoking cessation in general, while extending research to Spanish smokers. They may also help in the design of cessation and relapse-prevention interventions. Specifically, the results suggest that motivational enhancement is important throughout the cessation and maintenance periods. Copyright © 2015 Elsevier Ltd. All rights reserved.

Perioperative acute kidney injury (AKI) is an important predictor of long-term all-cause mortality after coronary artery bypass (CABG). However, the effect of AKI on long-term mortality after cardiac valve operations is hitherto undocumented. Perioperative renal injury and long-term all-cause mortality after valve operations were studied in a prospective cohort of patients undergoing solitary valve operations (n=2,806) or valve operations combined with CABG (n=1,260) with up to 18 years of follow-up. Postoperative serum creatinine increase was classified according to AKI 0-3. Patients undergoing solitary CABG (n=4,938) with cardiopulmonary bypass served as reference. In both valve and valve+CABG operations, postoperative renal injury of AKI stage 1 or higher was progressively associated with an increase in long-term mortality (HR 2.27, p<0.05 for valve; HR 1.65, p<0.05 for valve operations combined with CABG; HR 1.56, p<0.05 for CABG). Notably, the mortality risk increased already substantially at serum creatinine rises of 10-25%, i.e. far below the threshold for AKI stage 1 after valve operations (HR 1.39, p<0.05), but not after valve operations combined with CABG or CABG only. An increase in serum creatinine by more than 10%during the first week following valve operation is associated with an increased risk for long-term mortality following cardiac valve operation. Thus, AKI-classification clearly underestimates long-term mortality risk in patients undergoing valve operations. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

This study aims to examine the key determinants of long-term quality of life in breast cancer patients who are undergoing surgery using a multidimensional approach and taking into account preoperative and post-operative psychological characteristics such as anxiety, depression, posttraumatic growth, body image, and physical activity as well as medical parameters. The study involved 63 breast cancer patients from the Department of Surgery at the University of Szeged. Assessments occurred 1 day before surgery as well as 3 days and 18 months after surgery using the Spielberger State and Trait Anxiety Inventory (STAI), Beck's Depression Inventory (BDI), Functional Assessment of Cancer Therapy-Breast Cancer Scale (FACT-B), Posttraumatic Growth Inventory (PTGI) and Breast Impact of Treatment Scale (BITS). Data relating to physical activity, medical parameters and sociodemographic characteristics were also collected. The level of depression did not change over time. State anxiety decreased 18 months after the surgery compared to before the surgery; however, there was a greater decrease immediately after the surgery and then anxiety increased again 18 months later. Trait anxiety was associated with quality of life, posttraumatic growth and body image. Posttraumatic growth and the level of depression were found to be possible contributing factors to the increase in long-term quality of life. The results show that the timely detection and proper management of psychological distress and the enhancement of posttraumatic growth are of great value, as they might be important contributing factors to long-term quality of life in breast cancer patients.

The aims of this study were to assess the short- and long-term complication rates after video-assisted gastrostomy (VAG), the effects of age and gender on long-term complications and the effect of duration of gastrostomy tube retention on the need for gastroraphy when the gastrostomy device was removed. This was a retrospective study of children undergoing VAG at a single institution. Children who died or moved from the area were excluded. The rates of short- and long-term complications developing at 3-6 months or 2 or more years, respectively, were compared. A total of 170 children were studied, out of a cohort of 303 children. The median age at surgery was 2 years. The median duration of postoperative long-term follow-up was 5 years (2-9 years). The complications at the respective short and long-term follow-ups were as follows: granulation tissue, leakage, infection and vomiting. There were no differences in the short- versus long-term complication rates for gender and age. Children needing gastroraphy had used a gastrostomy device significantly longer compared with children with spontaneous closure. Complications after VAG decrease over time. A longer duration of gastrostomy device retention leads to increased need for gastroraphy.

This study compares long-term outcomes between intention-to-treat laparoscopic and open approaches to colorectal liver metastases (CLM), using inverse probability of treatment weighting (IPTW) based on propensity scores to control for selection bias. Patients undergoing liver resection for CLM by 5 surgeons at 3 institutions from 2000 to early 2014 were analysed. IPTW based on propensity scores were generated and used to assess the marginal treatment effect of the laparoscopic approach via a weighted Cox proportional hazards model. A total of 298 operations were performed in 256 patients. 7 patients with planned two-stage resections were excluded leaving 284 operations in 249 patients for analysis. After IPTW, the population was well balanced. With a median follow up of 36 months, 5-year overall survival (OS) and recurrence-free survival (RFS) for the cohort were 59% and 38%. 146 laparoscopic procedures were performed in 140 patients, with weighted 5-year OS and RFS of 54% and 36% respectively. In the open group, 138 procedures were performed in 122 patients, with a weighted 5-year OS and RFS of 63% and 38% respectively. There was no significant difference between the two groups in terms of OS or RFS. In the Brisbane experience, after accounting for bias in treatment assignment, long term survival after LLR for CLM is equivalent to outcomes in open surgery. Crown Copyright © 2015.

Many patients undergoing long-term doxycycline treatment do not regularly take their treatment because of photosensitivity. Our objective was to create an assay for determining doxycycline levels and to use hair samples for monitoring the compliance over a longer period of time. We tested sera and hair samples from patients treated with doxycycline by a suitable ultra-high performance liquid chromatography (UHPLC) based assay. We estimated that the speed of hair growth is roughly 1.25 cm per month and we were able to determine doxycycline levels over a 6-month period. We tested 14 patients treated with doxycycline and we found similar levels of doxycycline in the serum and the hair samples representing the last 4 months. Linear regression analysis revealed that the level of doxycycline in the serum remained stable over time (p = 0.7) but the level of doxycycline in the hair decreased significantly over time (p = 0.03) indicating a degradation of this molecule in the hair. We detected two patients who did not have antibiotic in the hair, indicating a lack of compliance that was also confirmed by interview. Hair samples can be used to test long-term compliance in patients to explain failures or relapses. Copyright © 2015 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

Is autologous chondrocyte implantation (ACI) an adequate treatment option for repair of cartilage defects in paediatric patients?

PubMed

Kaszkin-Bettag, Marietta

2013-08-01

Cartilage lesions in the knee of juvenile patients require an effective repair to regain life-long functional activity of the joint. Autologous chondrocyte implantation (ACI) is discussed to be advantageous over other methods for cartilage repair regarding long-term outcome. ACI has successfully been applied in juvenile patients, although currently recommended for patients ≥18 years of age. Only few controlled clinical trials present evidence of efficacy and safety of ACI in adolescent patients. ACI products have to undergo the process of a marketing authorisation application, including the submission of a paediatric investigation plan (PIP). Data from prospective clinical studies or retrospective collection of long-term data in paediatric patients should be submitted for risk-benefit evaluation by the Paediatric Committee (PDCO).

Sampath, Kartik; Dinani, Amreen M; Rothstein, Richard I

2016-06-01

The obesity epidemic, recognized by the World Health Organization in 1997, refers to the rising incidence of obesity worldwide. Lifestyle modification and pharmacotherapy are often ineffective long-term solutions; bariatric surgery remains the gold standard for long-term obesity weight loss. Despite the reported benefits, it has been estimated that only 1% of obese patients will undergo surgery. Endoscopic treatment for obesity represents a potential cost-effective, accessible, minimally invasive procedure that can function as a bridge or alternative intervention to bariatric surgery. We review the current endoscopic bariatric devices including space occupying devices, endoscopic gastroplasty, aspiration technology, post-bariatric surgery endoscopic revision, and obesity-related NOTES procedures. Given the diverse devices already FDA approved and in development, we discuss the future directions of endoscopic therapies for obesity.

In the context of psychological treatment, a sudden gain is a large and enduring improvement in symptom severity that occurs between two single therapy sessions. The influence of sudden gains on long-term outcomes and functional impairment in anxiety disorders is not well understood, and little is known with regard to panic disorder in particular. In addition, previous research on patients with anxiety disorders has produced inconsistent results regarding the relationship between sudden gains and cognitive change. We examined the incidence of sudden gains in a large sample (n = 116) of panic disorder patients undergoing exposure-focused cognitive-behavioral group therapy, and compared panic severity, functional impairment, and cognitive change in patients with and without sudden gains at posttreatment and 6-month follow-up. Participants who experienced sudden gains displayed lower levels of panic severity and functional impairment at posttreatment and 6-month follow-up than those who did not experience sudden gains. However, we observed no difference in cognitive changes between groups, either at posttreatment or at follow-up. Our results demonstrate that the beneficial effects of sudden gains on therapeutic outcomes not only extend to long-term and functional outcome measures but are also evident in less cognitive (i.e., exposure-focused) forms of psychological treatment. Sudden gains are common in panic disorder patients undergoing exposure-based cognitive-behavioral group therapy. Sudden gains during exposure-focused therapy are linked to greater improvement in panic disorder severity and functional impairment. The positive impact of sudden gains on panic disorder severity and functional impairment is maintained in the long term. Copyright © 2017 John Wiley & Sons, Ltd.

Infected pancreatic necrosis (IPN) is one of the most severe complications of acute pancreatitis (AP). Sequential surgical debridement represents one of the most effective treatments in terms of morbidity and mortality. The aim of this paper is to describe the quality of life and long-term results (e.g., nutritional, muscular, and pancreatic function) of patients treated by sequential necrosectomy at the Department of Surgery of the University of Insubria (Varese, Italy). Data were collected on patients undergoing sequential surgical debridement as treatment for IPN. The severity of AP was evaluated using the Ranson criteria, the Acute Physiology and Chronic Health Evaluation (APACHE II) Score, and the Sepsis Score, as well as the extent of necrosis. The surgical approach was through a midline or subcostal laparotomy, followed by exploration of the peritoneal cavity, wide debridement, and peritoneal lavage. The abdomen was either left open or closed partially with a surgical zipper, with multiple re-laparotomies scheduled until debridement of necrotic tissue was complete. The long-term evaluation focused on late morbidity, performance status, and abdominal wall function. In the majority of patients (68%), mixed flora were isolated. Pseudomonas aeruginosa was the microorganism identified most commonly (59%), often associated with Candida albicans or C. glabrata. The mean total hospital stay was 71+/-38 days (range 13-146 days), of which 24+/-19 days (range 0-66 days) were in the intensive care unit. Eight patients died, the deaths being caused by multiple organ dysfunction syndrome in seven patients and hemorrhage from the splenic artery in one. Normal exocrine and endocrine pancreatic function was observed in 28 patients (88%). At discharge, four patients had steatorrhea, which was temporary. Eight patients (23%) developed pancreatic pseudocysts, and in six, cystogastostomy was performed. Most patients (29/32, 91%) developed a post-operative hernia, but only five required surgical repair. All patients had a Short Form (SF)-36 score>60%, and 20 of the 32 patients (68%) had scores>70-80% (good quality of life). The worst scores were related to alcoholic pancreatitis. The degree of pancreatic failure (exocrine and endocrine function) is not related to the amount of pancreatic necrosis. Even with a need for repeated laparotomy and multiple surgical procedures, the abdominal wall capacity as well as long-term quality of life remain excellent.

This study aimed to evaluate the short- and long-term effects of conventional on-pump coronary bypass grafting (cCABG) compared with off-pump coronary artery bypass (OPCAB) on renal function. A retrospective review of patients undergoing coronary bypass grafting from 2004 through 2013 at a single center was conducted. Preoperative renal function, perioperative acute kidney injury, and long-term glomerular filtration were evaluated. Multivariable analyses were used to determine factors contributing to short- and long-term renal impairment. A total of 234 patients underwent cCABG, and 582 underwent OPCAB. Patients undergoing OPCAB were significantly older, had greater preoperative renal dysfunction, had greater functional dependence, and took more hypertension medications. Multivariable analyses found that 30-day acute kidney injury was an independent risk factor for a 10% decline in glomerular filtration rate at 1 and 5 years (P < 0.0001 and 0.002, respectively). However, the use of cardiopulmonary bypass was not found to influence long-term renal function (P = 0.78 at 1 year, P = 0.76 at 5 years). The percentage of patients experiencing a 10% drop in renal function from baseline at 1 year (33% OPCAB, 35% cCABG; P = 0.73) and 5 years (16% OPCAB, 16% cCABG; P = 0.93) were not significantly different. Independent predictors of acute kidney injury included baseline kidney function (P = 0.04) and age (P < 0.0001), whereas cardiopulmonary bypass did not affect the incidence (P = 0.17). A propensity-matched analysis confirmed these findings. Acute kidney injury is a risk factor for long-term renal dysfunction after either bypass method and was not greater after cCABG compared with OPCAB. Patients undergoing OPCAB did not experience greater decrease in long-term kidney function despite having worse baseline kidney function.

Persistence of pigmentation after a melanocyte-keratinocyte transplantation procedure (MKTP) is an important consideration for efficacy. We sought to determine long-term repigmentation of MKTP in vitiligo and other leukodermas. A retrospective review of electronic medical records was conducted for all MKTPs performed at Henry Ford Hospital between January 2009 and April 2014. Repigmentation was assessed by a 5-point grading scale (poor to excellent) and Vitiligo Area Scoring Index (VASI). One hundred patients had MKTP performed at 236 anatomically-based lesions (ABLs); 63 patients with 157 ABLs had long-term data available (12-72 months; median, 24 months). Segmental vitiligo, nonsegmental vitiligo, and physical leukoderma demonstrated improvement in VASI scores: -75.6 ± 24.6%, -59.2 ± 36.6%, and -32.4 ± 33.5%, respectively. In vitiligo, at 24, 48, and 72 months after MKTP, 53%, 64%, and 53% of ABLs, respectively, maintained >75% repigmentation. Skin phototype, age, and anatomic location of ABLs had no significant effect on the outcome of treatment. Limitations of the study include the retrospective design with uncontrolled, postoperative adjuvant treatments and inconsistent compliance to scheduled follow-up evaluations. MKTP provides satisfactory long-term repigmentation in the majority of appropriately selected patients with leukoderma. MKTP can maintain repigmentation for at least 72 months. Copyright © 2017.

Murphy, Maryanne

2016-09-01

Obesity is commonly encountered in veterinary patients. Although there are various published dietary approaches to achieving weight loss, successful long-term prevention of weight regain has proven elusive. Adding environmental and behavioral treatment strategies to a weight loss plan may help the veterinary team, the pet, and the pet owner maximize the effectiveness of the program. Because the owner directly affects the environment and behavior of the pet undergoing a weight loss plan, treatment strategies with an emphasis on owner involvement is the focus of this review. Veterinary use of the 5 A's behavioral counseling approach with the pet owner is discussed. Copyright © 2016 Elsevier Inc. All rights reserved.

In humans, the endometrium, the uterine mucosal lining, undergoes dynamic changes throughout the menstrual cycle and pregnancy. Despite the importance of the endometrium as the site of implantation and nutritional support for the conceptus, there are no long-term culture systems that recapitulate endometrial function in vitro. We adapted conditions used to establish human adult stem-cell-derived organoid cultures to generate three-dimensional cultures of normal and decidualized human endometrium. These organoids expand long-term, are genetically stable and differentiate following treatment with reproductive hormones. Single cells from both endometrium and decidua can generate a fully functional organoid. Transcript analysis confirmed great similarity between organoids and the primary tissue of origin. On exposure to pregnancy signals, endometrial organoids develop characteristics of early pregnancy. We also derived organoids from malignant endometrium, and so provide a foundation to study common diseases, such as endometriosis and endometrial cancer, as well as the physiology of early gestation.

To assess results of surgical correction of brachycephalic syndrome (including stenotic nares, elongated soft palate, and everted laryngeal saccules) in dogs and determine whether dogs with hypoplastic trachea have a less favorable long-term outcome. Retrospective case series. 62 dogs with brachycephalic syndrome. Medical records from 1991 to 2004 were reviewed for information regarding signalment, clinical signs, diagnosis, surgery, and long-term outcome. Surgical outcome was rated by owners as excellent, good, fair, or poor. Common abnormalities, treatments, and long-term outcomes among the 62 dogs were assessed. Predominantly affected breeds included English Bulldog, Pug, and Boston Terrier. Elongated soft palate was the most common abnormality (54/62 [87.1%] dogs); the most common combination of abnormalities was elongated soft palate, stenotic nares, and everted saccules (16/62 [25.8%] dogs). The English Bulldog was the most common breed for all abnormalities, including elongated soft palate (27/54 [50%] dogs), stenotic nares (14/36 [38.9%] dogs), everted saccules (20/36 [55.6%] dogs), hypoplastic trachea (7/13 [53.9%] dogs), and laryngeal collapse (2/5 [40%]). No dogs had everted saccules alone. Outcome did not differ between dogs under-going staphylectomy by use of laser or scissor resection. Follow-up information was obtained for 34 dogs; 16 (47.1%) had an excellent outcome, and 16 (47.1%) had a good outcome. Overall treatment success rate was 94.2%, and overall mortality rate was 3.2%. Surgical treatment of brachycephalic syndrome in dogs appeared to be associated with a favorable long-term outcome, regardless of age, breed, specific diagnoses, or number and combinations of diagnoses.

Autologous chondrocyte implantation (ACI) depends on the quality and quantity of implanted cells and is hindered by the fact that chondrocytes cultured for long periods of time undergo dedifferentiation. Here we have developed a reproducible and efficient chondrogenic protocol to redifferentiate chondrocytes isolated from osteoarthritis (OA) patients. We used morphological, histological and immunological analysis together with a RT-PCR detection of collagen I and collagen II gene expression to show that chondrocytes isolated from articular cartilage biopsies of patients and subjected to long-term culture undergo dedifferentiation and that these cells can be redifferentiated following treatment with the chimeric Activin A/BMP2 ligand AB235. Examination of AB235-treated cell pellets in both in vitro and in vivo experiments revealed that redifferentiated chondrocytes synthesized a cartilage-specific extracellular matrix (ECM), primarily consisting of vertically-orientated collagen fibres and cartilage-specific proteoglycans. AB235-treated cell pellets also integrated into the surrounding subcutaneous tissue following transplantation in mice as demonstrated by their dramatic increase in size while non-treated control pellets disintegrated upon transplantation. Thus, our findings describe an effective protocol for the promotion of redifferentiation of autologous chondrocytes obtained from OA patients and the formation of a cartilage-like ECM that can integrate into the surrounding tissue in vivo.

Research developing targeted treatment focused on coping with children's long-term pain after surgery is needed because of the high prevalence of chronic pain after surgery. This qualitative study aimed to: 1) understand the child's and family's experiences of pain over the course of their surgical experience, and 2) gather stakeholder input regarding potential barriers and facilitators of perioperative intervention delivery. Fifteen children ages 10 to 18 years who underwent recent major surgery, their primary caregivers, and 17 perioperative health care providers were interviewed. Interviews were coded using semantic thematic analysis. The perioperative period presented emotional challenges for families. Families felt unprepared for surgery and pain. Recovery and regaining physical functioning at home was challenging. Families struggled to return to valued activities. Families reported interest in a perioperative psychosocial intervention. Providers endorsed that families would benefit from enhanced coping skills. They emphasized that families would benefit from more detailed preparatory information. Providers suggested that flexible intervention delivery at home would be ideal. Research developing interventions addressing pain and anxiety in children undergoing major surgery is critically needed. The findings of the present study can inform intervention development with the aim of improving short- as well as long-term recovery in children undergoing major surgery. This qualitative study examined children and their parents' experience of long-term pain and recovery after major surgery, identifying barriers and facilitators of perioperative intervention delivery. Families experienced surgery as stressful, and felt underprepared for pain and recovery. Families and health care providers expressed interest in a preoperative intervention teaching coping skills.

Occlusion of the left atrial appendage (LAA) has become an integral and important part of the surgical treatment of atrial fibrillation. Different methods of surgical occlusion of the LAA have been associated with varying levels of short- and long-term success for closure. The purpose of this study was to evaluate long-term results of epicardial placement and endocardial occlusion in patients undergoing cardiac operative procedures. A total of 101 patients (average age 65.7 years) undergoing cardiac operative procedures with the epicardial AtriClip Exclusion System of the LAA were enrolled in the study. The AtriClip was placed via a sternotomy or a thoracotomy or from a thoracoscopic approach. Postoperative variables, such as thromboembolic events, clip stability and endocardial leakage around the device, were examined by transoesophageal echocardiography (TEE) and/or computed tomography. Perioperative clip implantation was achieved in 98% of patients. TEE and/or computed tomography conducted during the follow-up period, comprising 1873 patient-months with a mean duration of 18 ± 11 months, revealed no clip migration, no leakage around the device and no clot formation near the remnant cul-de-sac. During the follow-up period, 4 of the cardiac patients experienced transitory ischaemic attacks, whereas no patient experienced a cerebrovascular attack. The Epicardial AtriClip Exclusion System of the LAA appears to be a feasable and safe operative method with a high success rate. Long-term follow-up confirmed clip stability, complete occlussion of the LAA and absence of any atrial fibrilation-related thromboembolic events. These results need to be confirmed by a larger, multicentre study. © The Author 2017. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

To assess long-term temporal trends in population-based survival and cure rates in patients with esophageal cancer and compare them over the last 3 decades in the United States. We identified 62,523 patients with cancer of the esophagus and the gastric cardia diagnosed between 1973 and 2007 from the Surveillance, Epidemiology, and End Results database. Long-term cancer-related survival and cure rates were calculated. Stage-by-stage disease-related survival curves of patients diagnosed in different decades were compared. Influence of available variables on survival and cure was analyzed with logistic regression. Ten-year survival was 14% in all patients. Disease-related survival of esophageal cancer improved significantly since 1973. Median survival in Surveillance, Epidemiology, and End Results stages in local, regional, and metastatic cancers improved from 11, 10, and 4 months in the 1970s to 35, 15, and 6 months after 2000. Early stage, age 45 to 65 years at diagnosis and undergoing surgical therapy were independent predictors of 10-year survival. Cure rate improved in all stages during the study period and were 73%, 37%, 12%, and 2% in stages 0, 1, 2, and 4, respectively, after the year 2000. Percentage of patients undergoing surgery improved from 55% in the 1970s to 64% between 2000 and 2007. Proportion of patients diagnosed with in situ and local cancer remains below 30%. Long-term survival with esophageal cancer is poor but survival of local esophageal cancer improved dramatically over the decades. Complete cure of nonmetastatic esophageal cancer seems possible in a growing number of patients. Early diagnosis and treatment are crucial.

Glucocorticoids (GC) are commonly used in rheumatoid arthritis (RA) patients which bears a risk of hepatitis B virus (HBV) reactivation. The purpose of this study was to investigate the risk of HBV-related mortality under long-term low-dose GCs in Taiwanese RA patients. We retrospectively analyzed 45,423 RA patients using National Health Insurance Research Database from January 1999 to December 2011. Of them, 2204 patients had the diagnosis of HBV and were classified into four groups according to GCs regimens. Outcome comparison by Cox model analysis for liver-related mortality was performed. In this cohort, 90.5% were older than 40. One hundred and five patients had been treated with short-term large-dose GCs (Group A); 862 patients received GCs ≥20 mg/day for ≥3 days or a variable dose but did not meet Group C criteria (Group B); 689 patients were continuously treated with low-dose (<20 mg/day) GCs for ≥3 months for at least one session (Group C); and 548 patients had never been exposed to GCs (Group D). Two hundred and sixty-one patients had been exposed to antiviral agents, which was significantly higher in Group C. Fifty-eight patients (2.63%) died of acute hepatic failure, while no statistically significant difference between each groups (p = 0.074). Groups C and D comparison by two-sample test showed that long-term low-dose GC treatment was not associated with liver-related death after adjusting for malignancy. Long-term low-dose GC treatment was not associated with liver-related mortality in RA with concomitant HBV patients probably due to commonly applied antiviral therapy by rheumatologists.

A 16-year-old boy with sickle cell anemia undergoes routine screening with transcranial Doppler ultrasonography to assess the risk of stroke. This examination shows an abnormally elevated blood-flow velocity in the middle cerebral artery. The hemoglobin level is 7.2 g per deciliter, the reticulocyte count is 12.5%, and the fetal hemoglobin level is 8.0%. Long-term treatment with red-cell transfusion is initiated to prevent stroke. A hematologist recommends prophylactic iron-chelating therapy. PMID:21226580

The aim of this pilot study was to evaluate the changes in symptom severity and long-term health care cost after intensive short-term dynamic psychotherapy (ISTDP) individually tailored and administered to patients with psychotic disorders undergoing standard psychiatric care. Eleven therapists with different levels of expertise delivered an average of 13 one-hour sessions of graded ISTDP to 38 patients with psychotic disorders. Costs for health care services were compiled for a one-year period prior to the start of ISTDP (baseline) along with four one-year periods after termination. Two validated self-report scales, the Brief Symptom Inventory and the Inventory of Interpersonal Problems, were administered at intake and termination of ISTDP. Results revealed that health care cost reductions were significant for the one-year post-treatment period relative to baseline year, for both physician costs and hospital costs, and the reductions were sustained for the follow-up period of four post-treatment years. Furthermore, at treatment termination self-reported symptoms and interpersonal problems were significantly reduced. These preliminary findings suggest that this brief adjunctive psychotherapy may be beneficial and reduce costs in selected patients with psychotic disorders, and that gains are sustained in long-term follow-up. Future research directions are discussed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Over the last few decades, many authors have investigated the effect of periodontal disease and treatment on pulpal status with controversial results. This study was conducted to verify whether periodontal disease in a deep intrabony defect and complex therapy, including aggressive root planing such as in periodontal regeneration, have an influence on tooth vitality. One hundred thirty-seven patients who fulfilled the requirements were included. The collected data did not support the need for "preventive" root canal treatment in severely compromised teeth that are planned to undergo periodontal regenerative surgery.

Oxaliplatin, an anti-cancer chemotherapeutic agent used for the treatment of colorectal cancer, commonly causes gastrointestinal side-effects such as constipation, diarrhoea, nausea, and vomiting. Damage to enteric neurons may underlie some of these gastrointestinal side-effects, as the enteric nervous system (ENS) controls functions of the bowel. In this study, neuronal loss and changes to the structure and immunoreactivity of myenteric neuronal nitric oxide synthase (nNOS) neurons were examined in colonic segments from mice following exposure to oxaliplatin ex vivo and following repeated intraperitoneal injections of oxaliplatin over 3 weeks in vivo, using immunohistochemistry and confocal microscopy. Significant morphological alterations and increases in the proportion of NOS-immunoreactive (IR) neurons were associated with both short-term oxaliplatin exposure and long-term oxaliplatin administration, confirming that oxaliplatin causes changes to the myenteric neurons. Long-term oxaliplatin administration induced substantial neuronal loss that was correlated with a reduction in both the frequency and propagation speed of colonic migrating motor complexes (CMMCs) in vitro. Similar changes probably produce some symptoms experienced by patients undergoing oxaliplatin treatment. PMID:23486839

To determine predictors for long-term outcome in high-risk patients undergoing transcatheter edge-to-edge mitral valve repair (TMVR) for severe mitral regurgitation (MR). There is no data on predictors of long-term outcome in high-risk real-world patients. From August 2009 to April 2011, 126 high-risk patients deemed inoperable were treated with TMVR in two high-volume university centers. MR could be successfully reduced to grade ≤2 in 92.1% of patients (116/126 patients). Long-term clinical follow-up up to 5 years (95.2% follow-up rate) revealed a mortality rate of 35.7% (45/126 patients). Repeat mitral valve treatment (surgery or intervention) was needed in 19 patients (15.1%). Long-term clinical improvement was demonstrated with 69% of patients being in NYHA class ≤II. In a multivariable Cox regression analysis, the post-procedural grade of MR (hazard ratio [HR] 1.55 per grade, P = 0.035), the left ventricular ejection fraction (HR 0.58 for difference between 75th and 25th percentile, P = 0.031) and the glomerular filtration rate (HR 0.33 for 75th vs 25th percentile, P < 0.001) were independent predictors for long-term mortality. Patients with primary MR and a post-procedural MR grade ≤1 had the most favorable long-term outcome. This study determines predictors of long-term clinical outcome after TMVR and demonstrates that the grade of residual MR determines long-term survival. Our data suggest that it might be of benefit reducing residual MR to the lowest possible MR grade using TMVR-especially in selected high-risk patients with primary MR who are not considered as candidates for surgical MVR. © 2017, Wiley Periodicals, Inc.

Mitral valve repair under cardiopulmonary bypass was performed in three dogs with clinical signs associated with mitral regurgitation that were not controlled by medication. Mitral valve repair comprised circumferential annuloplasty and chordal replacement with expanded polytetrafluoroethylene. One dog died 2 years after surgery because of severe mitral regurgitation resulting from partial circumferential suture detachment. The others survived for over 5 years, but mild mitral valve stenosis persisted in one. The replaced chordae did not rupture in any dog. Mitral valve repair appears to be an effective treatment for mitral regurgitation in dogs. Chordal replacement with expanded polytetrafluoroethylene is a feasible technique, demonstrating long-term durability in dogs. However, mitral annuloplasty techniques need improvement. © 2012 British Small Animal Veterinary Association.

Background and study aims  Data on clinical outcomes of endoscopic drainage of debris-free pseudocysts (PDF) versus pseudocysts containing solid debris (PSD) are very limited. The aims of this study were to compare treatment outcomes between patients with PDF vs. PSD undergoing endoscopic ultrasound (EUS)-guided drainage via transmural stents. Patients and methods  Retrospective review of 142 consecutive patients with pseudocysts who underwent EUS-guided transmural drainage (TM) from 2008 to 2014 at 15 academic centers in the United States. Main outcome measures included TM technical success, treatment outcomes (symptomatic and radiologic resolution), need for endoscopic re-intervention at follow-up, and adverse events (AEs). Results  TM was performed in 90 patients with PDF and 52 with PSD. Technical success: PDF 87 (96.7 %) vs. PSD 51 (98.1 %). There was no difference in the rates for endoscopic re-intervention (5.5 % in PDF vs. 11.5 % in PSD; P =  0.33) or AEs (12.2 % in PDF vs. 19.2 % in PSD; P  = 0.33). Median long-term follow-up after stent removal was 297 days (interquartile range [IQR]: 59 - 424 days) for PDF and 326 days (IQR: 180 - 448 days) for PSD ( P  = 0.88). There was a higher rate of short-term radiologic resolution of PDF (45; 66.2 %) vs. PSD (21; 51.2 %) (OR = 0.30; 95 % CI: 0.13 - 0.72; P  = 0.009). There was no difference in long-term symptomatic resolution (PDF: 70.4 % vs. PSD: 66.7 %; P  = 0.72) or radiologic resolution (PDF: 68.9 % vs. PSD: 78.6 %; P  = 0.72) Conclusions  There was no difference in need for endoscopic re-intervention, AEs or long-term treatment outcomes in patients with PDF vs. PSD undergoing EUS-guided drainage with transmural stents. Based on these results, the presence of solid debris in pancreatic fluid collections does not appear to be associated with a poorer outcome.

Observational studies showed significant liver stiffness regression after sustained virological response, but long-term effects of antiviral therapy are still unknown. The aim of this study was to assess the magnitude of change in stiffness up to 5 years after therapy in hepatitis C patients undergoing antiviral treatment. Data of 153 patients were retrieved. Stiffness was assessed by Fibroscan at baseline, end of treatment, 6 months after treatment, and every year hereafter up to 5 years. Seventy patients were treated with interferon-based regimens and 83 with direct antiviral agents. Baseline cirrhosis was diagnosed in 53 (34.6%) patients. Sustained virological response was achieved in 112 patients, whereas 41 were non-responders. In responders, stiffness decreased from 12.3 kPa (9-17.8) to 6.6 kPa (5.3-7.4) at 5 years. A sharper decline was observed immediately after treatment (-2.5 kPa at the end of treatment and -3.7 kPa at 6 months), while from 1 year onwards, the magnitude of stiffness decrease was progressively lower. In non-responders, stiffness showed a slight decrease at the end of treatment (from 19.2 to 18.1 kPa), then returned to baseline levels at 6 months (19.4 kPa), and finally increased over time up to 23.7 kPa (15-32.5) at 5 years. The proportion of cirrhotic patients decreased by 50% at 6 months and finally fell < 5% at 4 years after treatment. Stiffness declines significantly after achieving response, and the magnitude of decline is greater in the first year after treatment, while it tends to plateau from 1 year onwards. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Hemorrhoidectomy is the most effective long-term treatment for hemorrhoids. Although it is possible to perform hemorrhoidectomy as a day case with a high degree of patient satisfaction, patients take an average of 14 days off work after surgery. Stapled hemorrhoidectomy is believed to be less painful than conventional hemorrhoidectomy and should allow an earlier return to work. The aim of this study was to compare both the immediate and the long-term results of stapled hemorrhoidectomy with diathermy hemorrhoidectomy in patients with prolapsing internal hemorrhoids in an intended day-care setting. Thirty-one patients were randomly assigned to undergo diathermy hemorrhoidectomy (n = 16) or stapled hemorrhoidectomy performed with a purpose-designed endoluminal stapling device, PPH01T (n = 15). All operations were planned as day or short-stay cases. All patients received lactulose, commenced preoperatively, together with postoperative topical glyceryl trinitrate and oral metronidazole. Patients were assessed by structured interview to assess their symptoms before and after surgery, with an intended follow-up of six months. All patients completed a 10-cm visual analog pain scale daily for the first ten days after surgery. The total pain score (sum of all pain scores) was significantly higher in the diathermy group (50 (range, 9.8-79.9) vs. 19.6 (range, 1.3-89.5), P = 0.03). Patients took a median of 14 (range, 3-21) days off work after diathermy hemorrhoidectomy compared with 10 (range, 3-38) days for the patients undergoing stapled hemorrhoidectomy (P = 0.15). At long-term follow-up, three patients (all in the stapled group) developed new symptoms of fecal urgency and anal pain, and three patients required further surgery to remove symptomatic external hemorrhoids after stapled hemorrhoidectomy. Although stapled hemorrhoidectomy is less painful in the short term, this does not lead to a significantly earlier return to work, and some patients develop new symptoms at long-term follow-up.

Methadone maintenance treatment (MMT) has been used as a treatment for opiate dependence since the mid-1960s. Evidence suggests that methadone binds to mu opiate receptors as do other opiates and induces changes in neurophysiological function. However, little is known, about how neural activity within the higher frequency gamma band (>30 Hz) while at rest changes in those stabilized on MMT despite its association with the excitation-inhibition balance within pyramidal-interneuron networks. Our study investigated differences in resting gamma power (37-41 Hz) between patients undergoing MMT for opiate dependence, illicit opiate users, and healthy controls subjects. Electroencephalographic data were recorded from 26 sites according to the international 10-20 system. Compared with the healthy controls subjects, people either undergoing MMT (mean difference [MD] = 0.32, 95% CI = 0.09-0.55, P < .01) or currently using illicit opiates (MD = 0.31, 95% CI = 0.06-0.56, P = .01) exhibited significant increased gamma power. The sLORETA (standardized low-resolution electromagnetic tomography) between-group comparison revealed dysfunctional neuronal activity in the occipital, parietal, and frontal lobes in the patients undergoing MMT. A more severe profile of dysfunction was observed in those using illicit opiates. Our findings suggest that long-term exposure to opioids is associated with disrupted resting state network, which may be reduced after MMT. © EEG and Clinical Neuroscience Society (ECNS) 2015.

The surface morphology in polycrystalline silicon (poly-Si) film is an issue regardless of whether conventional excimer laser annealing (ELA) or the newer metal-induced lateral crystallization (MILC) process is used. This paper investigates the stress distribution while undergoing long-term mechanical stress and the influence of stress on electrical characteristics. Our simulated results show that the nonuniform stress in the gate insulator is more pronounced near the polysilicon/gate insulator edge and at the two sides of the polysilicon protrusion. This stress results in defects in the gate insulator and leads to a nonuniform degradation phenomenon, which affects both the performance and the reliability in thin-film transistors (TFTs). The degree of degradation is similar regardless of bending axis (channel-length axis, channel-width axis) or bending type (compression, tension), which means that the degradation is dominated by the protrusion effects. Furthermore, by utilizing long-term electrical bias stresses after undergoing long-tern bending stress, it is apparent that the carrier injection is severe in the subchannel region, which confirms that the influence of protrusions is crucial. To eliminate the influence of surface morphology in poly-Si, three kinds of laser energy density were used during crystallization to control the protrusion height. The device with the lowest protrusions demonstrates the smallest degradation after undergoing long-term bending.

This study explored the effects of general (GA) and neuraxial (NA) anesthesia on the outcomes of primary total joint replacement (TJR) in terms of postoperative mortality, length of stay (LOS), and hospital treatment costs. From 1997 to 2010, this nationwide population-based study retrospectively evaluated 7,977 patients in Taiwan who underwent primary total hip or knee replacement. We generated two propensity-score-matched subgroups, each containing an equal number of patients who underwent TJR with either GA or NA. Of the 7,977 patients, 2,990 (37.5%) underwent GA and 4,987 (62.5%) underwent NA. Propensity-score matching was used to create comparable GA and NA groups adjusted for age, sex, comorbidities, surgery type, hospital volume, and surgeon volume. Survival over the first three years following surgery was similar. The proportion of patients alive up to 14 years postoperatively for those undergoing NA was 58.2% (95% confidence interval [CI] 50.4 to 66.0), and for those undergoing GA it was 57.3% (95% CI 51.4 to 63.2). Neuraxial anesthesia was associated with lower median [interquartile range; IQR] hospital treatment cost ($4,079 [3,805-4,444] vs $4,113 [3,812-4,568]; P < 0.001) and shorter median [IQR] LOS (8 [7-10] days vs 8 [6-10] days, respectively; P = 0.024). Our results support the use of NA for primary TJR. The improvements in hospital costs persist even when anesthesia costs are removed. The mechanism underlying the association between NA and long-term survival is unknown.

The aim of this study was to determine how older age and co-morbidities affect the treatment decision-making and long-term survival in elderly patients with symptomatic severe valvular heart diseases.A total of 181 elderly patients (mean age, 78.4 ± 3.4 years) hospitalized between January 2003 and June 2012 with symptomatic severe valvular heart diseases were enrolled. Cardiac and geriatric factors associated with treatment decision-making were analyzed. Survival outcomes were investigated.Surgical treatment was performed in 116 (64%) patients (surgical group) and 65 patients (36%) were treated conservatively (conservative group). The most common [62% (40/65)] reason for refusing surgical treatment was high operative risk as assessed by the physicians who initially cared for the patients. Multivariate logistic regression analysis identified female gender, chronic renal insufficiency, older age, pneumonia, and emergent status as independent predictors of the conservative treatment. Patients with isolated aortic valve disease tended to undergo an operation. Overall 5-year survival in the surgical group was 76.8% versus 42.9% in the conservative group (P < 0.0001). After matching using the propensity score, the surgical group still had a better long-term survival than the conservative group (P = 0.001). Cox regression analysis revealed conservative treatment as the single risk factor associated with poor long-term survival in all series.Approximately 40% of the elderly patients with symptomatic severe heart valve disease were treated conservatively despite a definite indication for surgical intervention. Cardiac and geriatric co-morbidities profoundly affect the treatment decision-making. Interdisciplinary discussion should be encouraged to optimize therapeutic options for elderly patients with valvular heart disease.

Facial hyperhidrosis can lead to serious emotional distress. Video-assisted thoracic sympathectomy resolves symptoms effectively, though it may be associated with compensatory hyperhidrosis, which may be more common in patients undergoing resection of the second thoracic ganglion. Oxybutynin has been used as a pharmacological approach to facial hyperhidrosis but the long-term results of this treatment are unclear. To evaluate the use of low oxybutynin doses in facial hyperhidrosis patients for at least six months. 61 patients were monitored for over six months and assessed according to the following variables: impact of hyperhidrosis on quality of life (QOL) before treatment and after six weeks, evolution of facial hyperhidrosis after six weeks and at the last consultation, complaints of dry mouth after six weeks and on last return visit, and improvement at other hyperhidrosis sites. Patients were monitored for 6 to 61 months (median=17 months). Thirty-six (59%) were female. Age ranged from 17-74 (median:45). Pre-treatment QOL was poor/very poor in 96.72%. After six weeks, 100% of patients improved QOL. Comparing results after six weeks and on the last visit, 91.8% of patients maintained the same category of improvement in facial hyperhidrosis, 3.3% worsened and 4.9% improved. Dry mouth complaints were common but not consistent throughout treatment. More than 90% of patients presented moderate/great improvement at other hyperhidrosis sites. Patients who had a good initial response to treatment maintained a good response long-term, did not display tachiphylaxis and experienced improvement on other hyperhidrosis sites.

Distal cholangiocarcinoma remains a rare cancer associated with a dismal outcome. There is a lack of effective treatment options and where disease is amendable to resection, surgery affords the best potential for long-term survival. The aim of this study was to examine the survival outcomes and prognostic factors of patients undergoing pancreatoduodenectomy for distal cholangiocarcinoma. Between January 2004 to May 2016, patients who had undergone pancreatoduodenectomy with histologically proven distal cholangiocarcinoma were identified. Clinicopathologic data and survival outcomes were reported. Pancreatoduodenectomy alone was performed in 20 patients (71%) and eight patients (29%) required concomitant vascular resection. The major complication rate was 43% (n = 12). Nineteen patients (68%) had node positive disease. Eighteen patients (64%) had R0 resection. The median survival was 36 months (95%CI 9.7 to 63.8) and 5-year survival rate was 24%. Univariate analysis identified ASA (P < 0.001), tumor grade (P = 0.009) and margin status (P = 0.042) as prognostic factors associated with survival. Long-term survival may be achieved in selected patients undergoing pancreatoduodenectomy for distal cholangiocarcinoma, especially in patients who achieved an R0 resection.

Surgeons often approach anal fissure with chemical denervation (Botulinum toxin, BT) instead of initial lateral internal sphincterotomy (LIS) due to concerns for long-term incontinence. We evaluated the characteristics and outcomes of patients who received BT or LIS. We performed a retrospective chart review of patients undergoing LIS and BT for anal fissure between 2009 and 2015. In 2015, a telephone survey was performed to evaluate durability, long-term incontinence and patient satisfaction. Ninety-four patients met criteria: 73 LIS and 21 BT. Age (BT 49 vs. LIS 52) was similar between groups (p = 1.0). Cleveland Clinic Fecal Incontinence (CCFI) score pre-intervention was higher in BT than LIS patients (2.1 vs. 0.4, p = 0.007) with fewer BT patients with perfect continence (50% vs. 88%). Telephone survey response was 61%. Fissure recurrence was significantly higher for BT than LIS patients (36% vs. 9%, p = 0.03). Patients undergoing LIS were less likely to recur. Both LIS and BT patients had some durable changes in continence raising the question of whether there is a safe technique. Copyright © 2017 Elsevier Inc. All rights reserved.

Therapeutic esophageal interventions for dysphagia and bleeding.

Siersema, Peter D

2006-07-01

This article reviews the most notable results of esophageal interventions for dysphagia and bleeding published in 2005. Long-term rubber tube placement was shown to be an interesting treatment option for difficult esophageal strictures. Two studies demonstrated that only 50% of patients who had undergone pneumatic dilation for achalasia were dysphagia-free after long-term follow-up. It was shown that patients with dysphagia from esophageal cancer should be treated by intraluminal radiotherapy (brachytherapy), whereas stent placement was preferable in those with a poor prognosis. Temporary stent placement is an option in patients undergoing radiotherapy for inoperable esophageal cancer to increase the dysphagia-free period. Two studies were published on the successful use of silicone-covered plastic stents for sealing of leaks after surgery of the esophagus. The optimal treatment for bleeding varices was confirmed to be endoscopic band ligation. A meta-analysis demonstrated that adding sclerotherapy to band ligation for secondary prophylaxis of bleeding varices had no effect on clinical outcome. In 2005, new techniques for the treatment of complicated strictures were presented. In addition, expanding indications for stents were reported. Finally, endoscopic band ligation was confirmed to be the most optimal technique for the treatment of varices.

Patients and animals with diabetes exhibit enhanced vulnerability to bacterial surgical infections. Despite multiple retrospective studies demonstrating the benefits associated with glycemic control in reducing bacterial infection after cardiac surgery, there are fewer guidelines on the use of glycemic control for noncardiac surgeries. In the current study, we investigated whether long-term (begun 2 weeks before surgery) or immediate (just before surgery) glycemic controls, continued postoperatively, can reduce surgical site infection in type 1 diabetic-induced rats. Rats were injected with streptozotocin to induce type 1 diabetes. Four groups of animals underwent surgery and thigh muscle Staphylococcus aureus bacteria challenge (1 × 10 colony forming units) at the time of surgery. Group 1 diabetic rats received insulin treatment just before surgery and continued until the end of study (short-term glycemic control group). Group 2 diabetic rats received insulin treatment 2 weeks before surgery and continued until the end of study (long-term glycemic control). Group 3 diabetic rats received no insulin treatment (no glycemic control group). Group 4 nondiabetic rats served as a healthy control group. Rats were euthanized at 3 or 6 days after surgery. Blood glucose and muscle bacterial burden were measured at 3 or 6 days after surgery. Glycemic control was achieved in both long- and short-term insulin-treated diabetic rats. Compared with untreated diabetic rats, the bacterial burden in muscle was significantly lower in both groups of glycemic controlled diabetic rats at 3 (all P < 0.003) and 6 (all P < 0.0001) days after surgery. A short-term glycemic control regimen, initiated just before surgery and bacterial exposure, was as effective in reducing surgical site infection as a long-term glycemic control in type 1 diabetic rats. These data suggest that immediately implementing glycemic control in type 1 diabetic surgical patients before undergoing noncardiac surgery may decrease the risk of infection.

This paper deals with the psychic disorders that frequently follow miscarriages. We specify the clinical forms under which such disorders appear and argue in favour of establishing a "Post-Abortion Syndrome" which would include the symptoms that form the basis of the psychopathological reactions that follow miscarriages. We will also study the psychological and psychopathological reactions to be found in couples -in both men and women-, who undergo fertility treatments, offering a brief description of the psychodynamic aspects that affect the couple. Furthermore, we will stress the biological and psychological risks that appear as a consequence of fertility treatments and offer an ethical evaluation of these risks, warning of the long-term consequences of human reproductive techniques.

Given the problematic nature of tardive dyskinesia in persons taking conventional antipsychotics, evaluation of newer atypical antipsychotic agents should include a systematic assessment of tardive dyskinesia liability. Results of a prospective double-blind, randomized study of schizophrenic patients who participated in 3 preclinical olanzapine studies and were treated with 5 to 20 mg/day of olanzapine (N = 1192) or haloperidol (N = 522) recently indicated a significantly lower risk of development of tardive dyskinesia with olanzapine treatment than haloperidol treatment. This article discusses the known effects of atypical antipsychotic medications on tardive dyskinesia movements (both withdrawal and persistent) and the incidence rate of tardive dyskinesia among schizophrenic patients undergoing long-term treatment with olanzapine or haloperidol.

There were a limited number of studies about β-cell function after insulin initiation in patients exposed to long durations of sulfonylurea treatment. In this study, we aimed to evaluate the recovery of β-cell function and the efficacy of concurrent sulfonylurea use after the start of long-acting insulin. In this randomized controlled study, patients with type 2 diabetes mellitus (T2DM), receiving sulfonylurea for at least 2 years with glycosylated hemoglobin (HbA1c) >7%, were randomly assigned to two groups: sulfonylurea maintenance (SM) and sulfonylurea reduction (SR). Following a 75-g oral glucose tolerance test (OGTT), we administered long-acting basal insulin to the two groups. After a 6-month follow-up, we repeated the OGTT. Among 69 enrolled patients, 57 completed the study and were analyzed: 31 in the SM and 26 in the SR group. At baseline, there was no significant difference except for the longer duration of diabetes and lower triglycerides in the SR group. After 6 months, the HbA1c was similarly reduced in both groups, but there was little difference in the insulin dose. In addition, insulin secretion during OGTT was significantly increased by 20% to 30% in both groups. A significant weight gain was observed in the SM group only. The insulinogenic index was more significantly improved in the SR group. Long-acting basal insulin replacement could improve the glycemic status and restore β-cell function in the T2DM patients undergoing sulfonylurea-based treatment, irrespective of the sulfonylurea dose reduction. The dose reduction of the concurrent sulfonylurea might be beneficial with regard to weight grain.

Peroral endoscopic myotomy (POEM) is an emerging procedure in the treatment of esophageal achalasia, a primary motility disorder. However, the long-term outcome of POEM in patients, who have previously undergone a Heller myotomy, is unknown. Using a local database, we identified patients with esophageal achalasia, who underwent POEM. We compared patients with a previous Heller myotomy to those, who had received none or only non-surgical therapy prior to the POEM procedure. We conducted follow-up examinations at 3, 12, and 24 months following the procedure. We included 66 consecutive patients undergoing POEM for achalasia, of which 14 (21.2 %) had undergone a prior Heller myotomy. In both groups, the preoperative Eckardt score was 7. Postoperatively, the non-Heller group experienced a more pronounced symptom relief at both 3-, 12-, and 24-month follow-up compared with the Heller group, and there was a tendency for the effect of POEM to reduce over time. We suggest that there is a correlation between preoperative measurements of gastroesophageal sphincter pressures and the chance of a successful POEM. POEM has a place in the treatment of esophageal achalasia in patients with a prior Heller myotomy and persistent symptoms as it is a safe procedure with acceptable long-term results.

The sedentary lifestyle, common to most modern societies, has turned obesity into an increasingly prevalent and universal problem. Obesity correlates positively with many diseases and health risk factors. Medical therapies currently used to treat obesity are generally limited in terms of long-term effectiveness. Bariatric surgery has been demonstrated an effective treatment for morbid obesity. Special nursing care considerations for bariatric surgery include providing wider cuffs for blood pressure checks, preventing deep venous thrombosis and post operation dietary education in order to accommodate changes in the gastrointestinal system. The purposes of this article were to introduce obesity therapy trends as well as to share nursing care principles for those undergoing bariatric surgery.

Mature Oocyte Cryopreservation for Fertility Preservation.

Liang, Tina; Motan, Tarek

2016-01-01

In recent decades, advances in cancer treatment have led to a dramatic improvement in long term survival. This has led to an increasing focus on quality of life after surviving cancer treatment, with fertility being an important aspect. Given the known reproductive risks of cancer therapies, there has been a growing interest in the field of fertility preservation (also referred to as oncofertility). Mature oocyte cryopreservation is no longer considered experimental and has become a realistic option for reproductive aged women prior to undergoing cancer treatment. Additionally, as cryopreservation techniques improve, mature oocyte cryopreservation is increasing being marketed to healthy women without cancer wishing to delay child bearing, also termed "social egg freezing". This chapter provides a review of the current technology, use, and outcomes of mature oocyte cryopreservation. It also outlines the ethical debate surrounding social egg freezing and directions for future research in female fertility preservation.

Prostate cancer is the second most common cancer in men and has high survivorship, yet little is known about the long-term risk of urinary adverse events (UAEs) after treatment. To compare the long-term UAE incidence across treatment and control groups. Using a matched-cohort design, we identified elderly men treated with external-beam radiotherapy (EBRT; n=44 318), brachytherapy (BT; n=14 259), EBRT+BT (n=11 835), radical prostatectomy (RP; n=26 970), RP+EBRT (n=1557), or cryotherapy (n=2115) for non-metastatic prostate cancer and 144 816 non-cancer control individuals from the population-based Surveillance, Epidemiology, and End Results-Medicare linked data from 1992-2007 with follow-up through 2009. The incidence of treated UAEs and time from cancer treatment to first UAE were analyzed in terms of propensity-weighted survival. Median follow-up was 4.14 yr. At 10 yr, all treatment groups experienced higher propensity-weighted cumulative UAE incidence than the control group (16.1%; hazard risk [HR] 1.0), with the highest incidence for RP+EBRT (37.8%; HR 3.19, 95% confidence interval [CI] 2.79-3.66), followed by BT+EBRT (28.4%; HR 1.97, CI 1.85-2.10), RP (26.6%; HR 2.44, CI 2.34-2.55), cryotherapy (23.4%; HR 1.56, CI 1.30-1.87), BT (19.8%; HR 1.43, CI 1.33-1.53), and EBRT (19.7%; HR 1.11, CI 1.07-1.16). Bladder outlet obstruction was the most common event. Men undergoing RP, RP+EBRT, and BT+EBRT experienced the highest UAE risk at 10 yr, although UAEs accrued differently over extended follow-up. The significant background UAE rate among non-cancer control individuals yields a risk attributable to prostate cancer treatment that is 17% lower than prior estimates. We show that treatment for prostate cancer, especially combinations of two treatments such as radiation and surgery, carries a significant risk of urinary adverse events such as urethral stricture. This risk increases with time since treatment, emphasizing that treatments have long-term effects. Copyright © 2014 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Hydroxychloroquine is used in the long-term therapy of systemic lupus erythematosus (SLE). Although considered to be a safe treatment, side effects have been documented. An uncommon side effect is thrombocytopenia. In order to establish the diagnosis of thrombocytopenia secondary to Hydroxychloroquine, non-pharmacological causes must be ruled out and it is necessary to determine a recurrence after re-exposure to the drug. We present one case of severe thrombocytopenia occurring in a patient with SLE undergoing treatment with Hydroxychloroquine.

Robotic technological aids in esophageal surgery.

Rebecchi, Fabrizio; Allaix, Marco E; Morino, Mario

2017-01-01

Robotic technology is an emerging technology that has been developed in order to overcome some limitations of the standard laparoscopic approach, offering a stereoscopic three-dimensional visualization of the surgical field, increased maneuverability of the surgical tools with consequent increased movement accuracy and precision and improved ergonomics. It has been used for the surgical treatment of most benign esophageal disorders. More recently, it has been proposed also for patients with operable esophageal cancer. The current evidence shows that there are no real benefits of the robotic technology over conventional laparoscopy in patients undergoing a fundoplication for gastroesophageal reflux disease (GERD), hiatal closure for giant hiatal hernia, or Heller myotomy for achalasia. A few small studies suggest potential advantages in patients undergoing redo surgery for failed fundoplication or Heller myotomy, but large comparative studies are needed to better clarify the role of the robotic technology in these patients. Robot-assisted esophagectomy seems to be safe and effective in selected patients; however, there are no data showing superiority of this approach over both conventional laparoscopic and open surgery. The short-term and long-term oncologic results of ongoing randomized controlled trials (RCTs) are awaited to validate this approach for the treatment of esophageal cancer.

The aim of the study was to evaluate the long-term safety (adverse events [AEs], laboratory parameters, vital signs, weight, and electrocardiograms) and effects on lipid profiles, especially triglyceride levels, of TAK-085 in Japanese patients with hypertriglyceridemia (triglyceride levels ≥150 mg/dL and <750 mg/dL). In this multicenter, open-label, randomized study, adults with hypertriglyceridemia undergoing lifestyle modification received TAK-085 2 g (2 g once daily; n = 165) or 4 g (2 g twice daily; n = 171), or EPA-E 1.8 g (0.6 g three times daily; n = 167) for 52 weeks. Patients were stratified for co-administration of a statin. TAK-085 was well tolerated throughout the 52-week study. Overall, no substantial differences were found in the tolerability of TAK-085 2 g, TAK-085 4 g, and EPA-E 1.8 g with incidence rates for AEs of 83.6%, 86.0%, and 89.2%, respectively. Most AEs were mild or moderate in severity. Triglyceride levels decreased from baseline in all groups by week 4, and the decreases were maintained throughout the study. At week 52 the reduction in triglycerides with TAK-085 2 g (-13.9%) was similar to that with EPA-E 1.8 g (-12.1%), whereas the reduction seen with TAK-085 4 g (-25.5%) was greater than that with EPA-E 1.8 g, as assessed by point estimates and 95% confidence intervals. TAK-085 was safe and well tolerated for up to 52 weeks of treatment in Japanese patients with hypertriglyceridemia undergoing lifestyle modification. Reductions in triglyceride levels achieved after 4 weeks were maintained at 52 weeks. Copyright © 2013 National Lipid Association. Published by Elsevier Inc. All rights reserved.

Dysphagia following treatment for head and neck cancer is one of the most significant morbidities impacting quality of life. Despite the value of prophylactic exercises to mitigate the impact of radiation on long-term swallowing function, adherence to treatment is limited. The purpose of this investigation was to explore the feasibility of a mobile health application to support patient adherence to swallowing therapy during radiation-based treatment. 36 patients undergoing radiation therapy were provided with the Vibrent™ mobile application as an adjunct to standard swallowing therapy. The application included exercise videos, written instructions, reminders, exercise logging, and educational content. 80% of participants used the app during treatment and logged an average of 102 exercise sessions over the course of treatment. 25% of participants logged at least two exercise sessions per day over the 7-week treatment period, and 53% recorded at least one session per day. Exit interviews regarding the patient experience with the Vibrent™ mobile application were largely positive, but also provided actionable strategies to improve future versions of the application. The Vibrent™ mobile application appears to be a tool that can be feasibly integrated into existing patient care practices and may assist patients in adhering to treatment recommendations and facilitate communication between patients and providers between encounters.

Familial Mediterranean Fever (FMF) is usually an autosomal recessive autoinflammatory disease characterized by recurrent attacks of fever and serositis. FMF develops before the age of 20 years in 90% of patients. It has intervals of 1 week to several years between attacks, which leads to renal dysfunction-amyloidosis. We report a case of atypical FMF that developed in a long-term hemodialysis patient. A 65-year-old Japanese female undergoing hemodialysis for 32 years was referred to our hospital with a fever of unknown origin (FUO) following cervical laminoplasty. The fever occurred as recurrent attacks accompanied by oligoarthralgia of the left hip and knee. We suspected FMF because of recurrent self-limited febrile attacks, although the patient showed atypical clinical features such as late-onset and highly frequent attacks. After receiving treatment, she achieved a complete response to colchicine. Therefore, a diagnosis of FMF was made based on the Tel-Hashomer criteria, which was confirmed by genetic testing. The case suggests that FMF may be of note in long-term hemodialysis patients developing FUO. © 2017 International Society for Hemodialysis.

Objective The “Heidelberg Model of Music Therapy for Chronic Tinnitus” is a manualized short term treatment (nine 50-minutes sessions of individualized therapy on five consecutive days). It has proven to be efficient in reducing tinnitus symptoms in the short run. Now the long-term impact of the treatment after up to 5.4 years should be explored. Materials and methods 206 patients who had attended the neuro-music therapy were addressed in a structured follow-up questionnaire survey. 107 complete questionnaires entered analysis. Follow-up time was 2.65 (SD 1.1) years. Results 76% of the patients achieved a reliable reduction in their tinnitus scores, the overall tinnitus distress as measured by the Mini-TQ diminished from 11.9 (SD = 4.9) to 7.4 (SD = 5.2) points, 87% of the patients were satisfied by the way they were treated during therapy, and 71% of the patients did not undergo any further treatment after. Evaluation of therapeutic elements displays, that only music therapy specific interventions were rated helpful by the patients. Tinnitus related factors (such as tinnitus pitch or loudness, time since onset) did not influence therapy outcome but female gender, positive therapeutic relationship, and higher initial Mini-TQ scores became apparent as factors predicting better chances for greater therapy success. Discussion The “Heidelberg Model of Music Therapy for Chronic Tinnitus” seems to be effective in the long run. The outcome effect size of d’ = 0.89, can be accounted for as “large” effect and falls into the upper range value compared to established treatments. PMID:22993646

Mesalazine seems to be effective in preventing recurrence of acute uncomplicated diverticulitis (AUD), but the optimal mesalazine scheme to achieve these results is still debated. To assess the effectiveness of two different mesalazine-based treatments in preventing recurrence of AUD and the occurrence of other complications of diverticular disease (DD) during a long-term follow-up. We reviewed 311 patients suffer from recent episode of AUD and undergoing to mesalazine treatment: 207 (group A, 105 males, median age 63 years, range 47-74 years) were treated with mesalazine 1.6 g for 10 days each month, whilst 104 (group B, 55 males, median age 65 years, range 50-72 years) were treated with mesalazine 1.6 g every day. Patients were followed-up every 6 months (median 7.5 months, range 5-13 months). Patients were followed-up for a mean time of 3 years (range 12-72 months). Overall, occurrence of complication recurred more frequently in group A than in group B (p = 0.030, log-rank test). Acute diverticulitis recurred in 17 (8.2%) patients in group A and in 3 (2.9%) in group B; diverticular bleeding occurred in 4 (1.9%) patients in group A and in 1 (0.96%) patient in group B; surgery was required in 3 (1.4%) patients in group A and in no (0%) patient in group B. This is the first study showing that long-term mesalazine treatment is significantly better that intermittent mesalazine treatment in preventing occurrence of DD complications after an attack of acute diverticulitis.

Patients undergoing radiotherapy for head and neck cancer (HNC) often experience malnutrition and dehydration during treatment. As a result, some centres place PEG tubes prophylactically (pPEG) to prevent these negative consequences. However, recent research has suggested that pPEG use may negatively affect swallowing physiology, function and/or quality of life, especially in the long term. The purpose of this study was to systematically review the literature on pPEG use in HNC patients undergoing radiotherapy and to determine its impact on swallowing-related outcomes. The following electronic databases were searched for all relevant primary research published through February 24, 2014: AMED, CINAHL, the Cochrane Library, Embase, Healthstar, Medline, and PsycINFO. Main search terms included HNC, radiotherapy, deglutition disorders, feeding tube(s), and prophylactic or elective. References for all accepted papers were hand searched to identify additional relevant research. Methodological quality was assessed using Cochrane's Risk of Bias. At all levels, two blinded raters provided judgments. Discrepancies were resolved by consensus. The search retrieved 181 unique citations. Twenty studies met our inclusion criteria. Quality assessment revealed that all studies were at risk for bias due to non-randomized sampling and unreported or inadequate blinding. Ten studies demonstrated selection bias with significant baseline differences between pPEG patients and controls. Results regarding the frequency and severity of dysphagia and swallowing-related outcomes were varied and inconclusive. The impact of pPEG use on swallowing and swallowing-related outcomes remains unclear. Well-controlled, randomized trials are needed to determine if pPEG places patients at greater risk for developing long-term dysphagia.

The aim of the study was to assess differences in verbal fluency, working memory and executive functions in two subgroups of alcohol-dependent patients, those undergoing short-term abstinence (STA) and those undergoing long-term abstinence (LTA), and to compare the level of cognitive functions in patients after long-term abstinence with healthy subjects. The study group consisted of 106 alcohol-dependent patients (53 immediately after drinking at least 3 days and 53 after at least one-year abstinence). The control group comprised 53 subjects, whose age, sex and education levels matched those of the patients in the experimental group. The dependence intensity was assessed using SADD and MAST scales. The neuropsychological assessment was based on the FAS Test, Stroop Test and TMT A&B Test. The results obtained for alcohol-dependent patients revealed significant disturbances of cognitive functions. Such results indicate the presence of severe frontal cerebral cortex dysfunctions. Frontal cortex dysfunctions affecting the verbal fluency and working memory subsystems and the executive functions also persisted during long-term abstinence periods. No significant correlations between the duration of dependence, quantity of alcohol consumed and efficiency of the working memory and executive functions were observed in alcohol-dependent subjects after short-term or long-term abstinence.

To evaluate long-term device outcomes following primary artificial urinary sphincter (AUS) implantation. We identified 1802 male patients with stress urinary incontinence that underwent AUS placement from 1983 to 2011. Of these, 1082 (60%) were involving primary implantations and comprise the study cohort. Multiple clinical and surgical variables were evaluated for potential association with treatment failure, defined as any secondary surgery. Patient follow-up was obtained through office examination, operative report, and written or telephone correspondence. Patients undergoing AUS implantation had a median age of 71 years (interquartile range 66-76) and median follow-up of 4.1 years (interquartile range 0.8-7.7). Overall, 338 of 1082 patients (31.2%) underwent secondary surgery, including 89 for device infection and/or erosion, 131 for device malfunction, 89 for urethral atrophy, and 29 for pump malposition or tubing complications. No patient-related risk factors were independently associated with an increased risk of secondary surgery on multivariable analysis. Secondary surgery-free survival was 90% at 1 year, 74% at 5 years, 57% at 10 years, and 41% at 15 years. Primary AUS implantation is associated with acceptable long-term outcomes. Recognition of long-term success is important for preoperative patient counseling. Copyright © 2015 Elsevier Inc. All rights reserved.

Intertidal organisms, especially the sessile species, often experience long-term periodic air exposure during their lives. Learning the biochemical and physiological responses of intertidal organisms to long-term periodic air exposure and the relationship to duration of air exposure provides insight into adaptation to this variably stressful environment. We studied the Manila clam, Ruditapes philippinarum, an important species in world aquaculture, as a model to evaluate survival, growth, lipid composition, oxygen consumption, oxidative damage, and antioxidant enzyme activity in relation to the duration of air exposure in a long-term (60 days) laboratory study of varying durations of periodic emersion and re-immersion. Our results show: (1) clams undergoing a longer period of air exposure had lower survival and growth compared to those given a shorter exposure, (2) levels of oxidative damage and activities of antioxidant enzymes were higher in all air exposure treatments, but did not increase with duration of air exposure, and (3) the content of docosahexaenoic acid increased with duration of air exposure. Our results can largely be interpreted in the context of the energy expenditure by the clams caused by aerobic metabolism during the daily cycle of emersion and re-immersion and the roles of docosahexaenoic acid against oxidative stress.

2007-01-01

Recombinant factor VIIa (NovoSeven; also known as recombinant activated factor VII or eptacog alfa) is indicated as an intravenous haemostatic agent in haemophilia patients with inhibitors to clotting factors VIII or IX. In noncomparative trials in haemophilia patients with inhibitors, on-demand home treatment with recombinant factor VIIa was effective in controlling episodes of mild to moderate bleeding and well tolerated, with early treatment being associated with a greater rate of success and the need for fewer doses than delayed treatment. Prophylactic treatment with recombinant factor VIIa was also effective in maintaining haemostasis in patients with this indication undergoing surgery. Relative to prior treatment with plasma-derived agents, treatment with recombinant factor VIIa was associated with improvements in health-related quality of life in a cost-utility study in haemophilia patients with inhibitors in Australia. In well designed decision-model cost analyses conducted from a healthcare payer perspective in several countries, on-demand treatment with recombinant factor VIIa to control mild to moderate bleeding episodes in this patient population was predicted to be cost saving or cost neutral relative to on-demand treatment with intravenous activated prothrombin complex concentrate (aPCC). Although the acquisition cost of recombinant factor VIIa was greater than that of aPCC in some studies, the greater initial efficacy of recombinant factor VIIa than aPCC resulted in lower predicted total medical costs. Results were generally robust to plausible changes in key parameters. Orthopaedic surgery with recombinant factor VIIa to maintain haemostasis in haemophilia patients with inhibitors was generally predicted to be cost saving, relative to not having surgery, over the medium to long term in modelled cost analyses from a healthcare payer perspective in the UK and US. The initial cost of surgery was high, but the difference in costs between patients undergoing or not undergoing surgery was predicted to decline over time, as savings were realised from the decrease in the number of bleeding episodes requiring treatment in patients who underwent surgery. In haemophilia patients with inhibitors, recombinant factor VIIa is clinically effective in controlling mild to moderate bleeds, and in maintaining haemostasis in patients undergoing orthopaedic surgery. Available pharmacoeconomic data from several countries, despite inherent limitations, support the use of recombinant factor VIIa as a treatment option that is at least cost neutral relative to aPCC in treating mild to moderate bleeds in this patient population. In addition, orthopaedic surgery with recombinant factor VIIa to maintain haemostasis in haemophilia patients with inhibitors is generally cost saving relative to not having surgery over the medium to long term, as the acquisition costs of recombinant factor VIIa are offset by cost savings resulting from the decrease in the number of joint-related bleeds.

Pediatric hypnosis: pre-, peri-, and post-anesthesia.

Pediatric hypnosis has a useful role in pre-, peri-, and post-anesthesia to minimize anticipatory anxiety, and as adjunctive treatment to reduce and control pain. This article reviews the literature in the use of hypnosis in pediatric anesthesia to highlight its role and relevancy. Current research indicates there is an immediate and enduring impact, and long-term benefits of this child-centered intervention. Hypnosis can be included in presurgical consultations to establish cooperation and signals for increasing comfort and to address fears and provide suggestions for rapid recovery with changed expectations for the child's own benefit. Thus prepared, the child is in a heightened state of receptivity and statements and suggestions carry through to peri- and post-anesthesia, when hypnosis can help with extubation, reduce nausea, and ease recovery. The Magic Glove is one hypno-anesthesia technique that simultaneously addresses pain and anxiety. The process of hypnosis requires training and supervised practice. Patients in hypnosis treatment conditions have less anxiety and shorter hospital stays and experience less long-term pain and discomfort than do patients in control conditions. There appears little reason not to provide hypnosis as an adjunctive treatment for pediatric patients undergoing anesthesia. © 2012 Blackwell Publishing Ltd.

Background New highly efficacious direct-acting antiviral (DAA) therapies are available to treat chronic hepatitis C viral (HCV) infection. Real-world, patient-centered data on harms and benefits associated with these therapies are needed. Methods PROP UP is a multi-center prospective observational study that plans to enroll 1,600 patients starting treatment with recently-approved DAA regimens. Informed by extensive input from a HCV patient engagement group who prioritized outcomes most important to them, patient-reported outcomes will be characterized using surveys at five time points: Baseline (T1), treatment week 4 (T2), end of treatment (T3), 12 weeks post-treatment (T4), 12 months post-treatment (T5). Outcomes (1) Changes in side effects, functioning, pre-existing conditions, and out-of-pocket costs during therapy (T1 vs T2/T3); (2) Medication adherence in relation to a history of mental health/substance abuse, treatment regimens, pill burden, reasons for missed doses, and cure rates; (3) Short term impact of cure on functioning and amelioration of symptoms (T1 vs T4); (4) Long-term treatment harms or benefits of cure on symptoms, side effects, pre-existing conditions, and functioning (T1 vs T5). Similarities between regimens will be examined where comparisons are appropriate and meaningful. Conclusion PROP UP complements previous clinical trials by focusing on patient-reported outcomes in a representative sample of patients treated in clinical practice, by collaborating with a patient engagement group, by characterizing the experiences of vulnerable subgroups, and by investigating long-term harms and benefits of treatments. PROP UP is designed to provide novel and detailed information to support informed decision-making for patients and providers contemplating HCV treatment (PCORI CER-1408-20660; NCT02601820).

A retrospective review of the medical records of 41 horses requiring abdominal surgery for sand colic. The diagnosis of sand colic was made when sand was found to be the cause of impaction of the gastrointestinal tract during surgical exploration. The most common clinical signs at presentation were abdominal pain, abdominal distension and diarrhoea. A statistically significant association was found between the respiratory rate on arrival and short-term survival. Sand impaction at multiple locations was detected in one-third of the horses. Concurrent pathology was detected in half of the horses. Four horses were euthanased during surgery; of those that recovered from surgery, 35/37 (95%) were discharged from hospital. Short- and long-term complications were similar to those previously reported. Long-term (1 year) survival of the horses discharged was 100%. The good prognosis for horses undergoing surgery for the treatment of sand impaction supports early surgical intervention in cases where large amounts of sand are suspected.

The long-term outcomes of branched-chain amino acid (BCAA) administration in patients undergoing hepatic resection remain unclear. The aim of this study is to assess the impact of oral supplementation with BCAA-enriched nutrients on postoperative quality of life (QOL) in patients undergoing liver resection. A prospective randomized clinical trial was conducted in 96 patients undergoing hepatic resection. Patients were randomly assigned to receive BCAA supplementation (AEN group, n = 48) or a conventional diet (control group, n = 48). Postoperative QOL and short-term outcomes were regularly and continuously evaluated in all patients using a short-form 36 (SF-36) health questionnaire and by measuring various clinical parameters. This study demonstrated a significant improvement in QOL after hepatectomy for liver neoplasm in the AEN group based on the same patients' preoperative SF-36 scores (P < 0.05). Perioperative BCAA supplementation preserved liver function and general patient health in the short term for AEN group patients compared to those not receiving the nutritional supplement. BCAA supplementation improved postoperative QOL after hepatic resection over the long term by restoring and maintaining nutritional status and whole-body kinetics. This study was registered at http://www.clinicaltrials.gov (registration number: NCT00945568).

Stanford A acute aortic dissection (AAD) is a life-threatening emergency, typically occurring in hypertensive patients, requiring immediate surgical repair. The aim of this study was to evaluate early outcomes and long-term survival of hypertensive patients in comparison to normotensive patients suffering from Stanford A AAD. In our center, 240 patients with Stanford A AAD underwent aortic surgical repair from January 2006 to April 2015. After statistical and logistic regression analysis, Kaplan-Meier survival estimation was performed, with up to 9-year follow-up. The proportion of hypertensive patients suffering from Stanford A AAD was 75.4% (n=181). There were only few statistically significant differences in terms of basic demographics, comorbidities, preoperative baseline and clinical characteristics of hypertensive patients in comparison to normotensive patients. Hypertensive patients were significantly older (p=0.008), more frequently received hemi-arch repair (p=0.028) and selective brain perfusion (p=0.001). Our study showed similar statistical results in terms of 30-day mortality (p=0.196), long-term overall cumulative survival of patients (Log-Rank p=0.506) and survival of patients free from cerebrovascular events (Log-Rank p=0.186). Furthermore, subgroup analysis for long-term survival in terms of men (Log-Rank p=0.853), women (Log-Rank p=0.227), patients under and above 65 years of age (Log-Rank p=0.188 and Log-Rank p=0.602, respectively) and patients undergoing one of the three types of aortic repair surgery showed similar results for normotensive and hypertensive patient groups. Subgroup analysis for long-term survival of patients free from cerebrovascular events for women, patients under 65 years of age and patients undergoing aortic arch repair showed significant differences between the two groups in favor of hypertensive patients. Hypertensive patients suffering from Stanford A AAD were older, more frequently received hemi-arch replacement and were not associated with increased risk of 30-day mortality and poorer long-term survival compared to normotensive patients.

Bariatric surgery is effective in reducing all-cause and cause-specific long-term mortality. Whether the long-term mortality benefit of surgery applies to all ages at which surgery is performed is not known. To examine whether gastric bypass surgery is equally effective in reducing mortality in groups undergoing surgery at different ages. All-cause and cause-specific mortality rates and hazard ratios (HRs) were estimated from a retrospective cohort within 4 categories defined by age at surgery: younger than 35 years, 35 through 44 years, 45 through 54 years, and 55 through 74 years. Mean follow-up was 7.2 years. Patients undergoing gastric bypass surgery seen at a private surgical practice from January 1, 1984, through December 31, 2002, were studied. Data analysis was performed from June 12, 2013, to September 6, 2015. A cohort of 7925 patients undergoing gastric bypass surgery and 7925 group-matched, severely obese individuals who did not undergo surgery were identified through driver license records. Matching criteria included year of surgery to year of driver license application, sex, 5-year age groups, and 3 body mass index categories. Roux-en-Y gastric bypass surgery. All-cause and cause-specific mortality compared between those undergoing and not undergoing gastric bypass surgery using HRs. Among the 7925 patients who underwent gastric bypass surgery, the mean (SD) age at surgery was 39.5 (10.5) years, and the mean (SD) presurgical body mass index was 45.3 (7.4). Compared with 7925 matched individuals not undergoing surgery, adjusted all-cause mortality after gastric bypass surgery was significantly lower for patients 35 through 44 years old (HR, 0.54; 95% CI, 0.38-0.77), 45 through 54 years old (HR, 0.43; 95% CI, 0.30-0.62), and 55 through 74 years old (HR, 0.50; 95% CI, 0.31-0.79; P < .003 for all) but was not lower for those younger than 35 years (HR, 1.22; 95% CI, 0.82-1.81; P = .34). The lack of mortality benefit in those undergoing gastric bypass surgery at ages younger than 35 years primarily derived from a significantly higher number of externally caused deaths (HR, 2.53; 95% CI, 1.27-5.07; P = .009), particularly among women (HR, 3.08; 95% CI, 1.4-6.7; P = .005). Patients undergoing gastric bypass surgery had a significantly lower age-related increase in mortality than severely obese individuals not undergoing surgery (P = .001). Gastric bypass surgery was associated with improved long-term survival for all patients undergoing surgery at ages older than 35 years, with externally caused deaths only elevated in younger women. Gastric bypass surgery is protective against mortality even for older patients and also reduces the age-related increase in mortality observed in severely obese individuals not undergoing surgery.

Does dilation and curettage versus expectant management for spontaneous abortion in patients undergoing in vitro fertilization affect subsequent endometrial development?

PubMed

In in vitro fertilization patients, treatment of spontaneous abortion with dilation and curettage (D&C) versus expectant management has no long-term effect on subsequent endometrial development, as measured by change in endometrial thickness. A transient reduction in endometrial thickness was found within the first 6 months after D&C, which is a novel finding, but it is likely to have little or no effect on pregnancy rates given the small absolute effect on endometrial thickness.

AORTIC COARCTATION: RECENT DEVELOPMENTS IN EXPERIMENTAL AND COMPUTATIONAL METHODS TO ASSESS TREATMENTS FOR THIS SIMPLE CONDITION

2010-01-01

Coarctation of the aorta (CoA) is often considered a relatively simple disease, but long-term outcomes suggest otherwise as life expectancies are decades less than in the average population and substantial morbidity often exists. What follows is an expanded version of collective work conducted by the authors’ and numerous collaborators that was presented at the 1st International Conference on Computational Simulation in Congenital Heart Disease pertaining to recent advances for CoA. The work begins by focusing on what is known about blood flow, pressure and indices of wall shear stress (WSS) in patients with normal vascular anatomy from both clinical imaging and the use of computational fluid dynamics (CFD) techniques. Hemodynamic alterations observed in CFD studies from untreated CoA patients and those undergoing surgical or interventional treatment are subsequently discussed. The impact of surgical approach, stent design and valve morphology are also presented for these patient populations. Finally, recent work from a representative experimental animal model of CoA that may offer insight into proposed mechanisms of long-term morbidity in CoA is presented. PMID:21152106

Epiploic foramen entrapment (EFE) has been associated with reduced post operative survival compared to other types of colic but specific factors associated with reduced long-term survival of these cases have not been evaluated in a large number of horses using survival analysis. To describe post operative survival of EFE cases and to identify factors associated with long-term survival. A prospective, multicentre, international study was conducted using clinical data and long-term follow-up information for 126 horses diagnosed with EFE during exploratory laparotomy at 15 clinics in the UK, Ireland and USA. Descriptive data were generated and survival analysis performed to identify factors associated with reduced post operative survival. For the EFE cohort that recovered following anaesthesia, survival to hospital discharge was 78.5%. Survival to 1 and 2 years post operatively was 50.6 and 34.3%, respectively. The median survival time of EFE cases undergoing surgery was 397 days. Increased packed cell volume (PCV) and increased length of small intestine (SI) resected were significantly associated with increased likelihood of mortality when multivariable analysis of pre- and intraoperative variables were analysed. When all pre-, intra- and post operative variables were analysed separately, only horses that developed post operative ileus (POI) were shown to be at increased likelihood of mortality. Increased PCV, increased length of SI resected and POI are all associated with increased likelihood of mortality of EFE cases. This emphasises the importance of early diagnosis and treatment and the need for improved strategies in the management of POI in order to reduce post operative mortality in these cases. The present study provides evidence-based information to clinicians and owners of horses undergoing surgery for EFE about long-term survival. These results are applicable to university and large private clinics over a wide geographical area. © 2011 EVJ Ltd.

End stage renal disease patients undergoing long-term dialysis are at risk for abnormal concentrations of certain essential and non-essential trace metals and high oxidative stress. We evaluated the effects of zinc (Zn) supplementation on plasma aluminum (Al) and selenium (Se) concentrations and oxidative stress in chronic dialysis patients. Zn-deficient patients receiving continuous ambulatory peritoneal dialysis or hemodialysis were divided into two groups according to plasma Al concentrations (HA group, Al > 50 μg/L; and MA group, Al > 30 to ≤ 50 μg/L). All patients received daily oral Zn supplements for two months. Age- and gender-matched healthy individuals did not receive Zn supplement. Clinical variables were assessed before, at one month, and after the supplementation period. Compared with healthy subjects, patients had significantly lower baseline plasma Se concentrations and higher oxidative stress status. After two-month Zn treatment, these patients had higher plasma Zn and Se concentrations, reduced plasma Al concentrations and oxidative stress. Furthermore, increased plasma Zn concentrations were related to the concentrations of Al, Se, oxidative product malondialdehyde (MDA), and antioxidant enzyme superoxide dismutase activities. In conclusion, Zn supplementation ameliorates abnormally high plasma Al concentrations and oxidative stress and improves Se status in long-term dialysis patients. PMID:23609777

To determine the long-term effect of argon plasma coagulation (APC) of gastric inlet patches in the cervical esophagus for patients suffering from globus sensation. We intended to follow up all patients between 2004 and 2011 (n = 49) who received argon plasma ablation of gastric inlet patches for globus sensation at our clinic. Symptoms were assessed by a visual analogue scale (VAS) in 31 of 49 patients. Follow-up endoscopy of the upper gastrointestinal tract was performed to confirm residual or relapsed cervical inlet patches. After a median period of 27 months, APC was assessed as a successful therapy in 23 of 31 patients (74%). VAS scores decreased significantly from 7.6 to 4.0 in the long term. Twenty-two of 31 patients were willing to undergo follow-up endoscopy. Endoscopy revealed recurrent/residual gastric inlet patches after APC in 11 of 22 cases. These patients suffered from a significant relapse of symptoms in the postinterventional period (p < 0.001). This retrospective study indicates that APC of gastric inlet patches for the treatment of globus sensation might be a sufficient therapy option. Recurrences or residual heterotopic gastric mucosa are possible and seem to be associated with a relapse of symptoms. Therefore, endoscopic follow-up and retreatment might be necessary if globus sensation is not sufficiently eliminated. © 2013 S. Karger AG, Basel.

Percutaneous pulmonary valvuloplasty is the preferred interventional procedure for pulmonary valve stenosis. The aim of this study was to evaluate the effectiveness of this technique, assess the factors leading to its success, and determine the long-term results in the pediatric population. The study included 53 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty between December 1985 and December 2000. Right ventricular size and functional echocardiographic parameters, such as pulmonary regurgitation and residual transvalvular gradient, were assessed during long-term follow-up. Peak-to-peak transvalvular gradient decreased from 74 mmHg [interquartile range, 65-100 mmHg] to 20 mmHg [interquartile range, 14-34 mmHg]. The procedure was unsuccessful in 2 patients (3.77%). The immediate success rate was 73.58%. Follow-up ranged from 10 years to 24 years (median, 15 years). During follow-up, all patients developed late pulmonary regurgitation which was assessed as grade II in 58.4% and grade III in 31.2%. There was only 1 case of long-term restenosis (2.1%). Severe right ventricular dilatation was observed in 27.1% of the patients. None of the patients developed significant right ventricular dysfunction. Pulmonary valve replacement was not required in any of the patients. Percutaneous balloon valvuloplasty is an effective technique in the treatment of pulmonary valve stenosis with good long-term results. Copyright © 2013 Sociedad Española de Cardiología.

Interferon beta-1a is available as an immunomodulating agent for relapsing forms of multiple sclerosis. Common side effects include flu-like symptoms, asthenia, anorexia, and administration site reaction. Kidney disorders are rarely reported. In this study we describe the case of a woman who has been undergoing treatment with interferon beta-1a for multiple sclerosis for 5 years. She developed a hemolytic-uremic syndrome with intravascular hemolysis in a context of severe hypertension. A kidney biopsy showed a thrombotic microangiopathy. This observation highlights an uncommon side effect of long-term interferon beta-1a therapy. Pathophysiological mechanisms leading to this complication might be explained by the antiangiogenic activity of interferon. PMID:23950639

Chronic atomoxetine treatment during adolescence does not influence decision-making on a rodent gambling task, but does modulate amphetamine's effect on impulsive action in adulthood.

In addition to the symptoms of inattention, hyperactivity, and impulsivity, individuals with attention deficit hyperactivity disorder exhibit impaired performance on tests of real-world cost/benefit decision-making. Atomoxetine, a nonstimulant drug approved for the treatment of attention deficit hyperactivity disorder, is a selective norepinephrine reuptake inhibitor administered chronically during adolescence, a time during which the frontal brain regions necessary for executive function undergo extensive maturation. This treatment protocol can affect behavior well into adulthood, but whether it produces long-term changes in complex decision-making has not been investigated. Twenty-four Long-Evans rats were administered saline or 1.0 mg/kg atomoxetine daily from postnatal day 40 to 54. Two weeks after treatment, the adult rats were trained and assessed on the rodent gambling task, in which the animals chose from four options varying in reward, punishment, and uncertainty. Impulsive action was also measured by recording the number of premature responses made. Regardless of the treatment administered during adolescence, rats learned to favor the advantageous options characterized by small, low-penalty rewards in lieu of the larger, higher-penalty reward options. Rodent gambling task performance was then assessed following acute treatment with atomoxetine (0.1-1.0 mg/kg) and amphetamine (0.3-1.5 mg/kg). Across groups, the highest dose of atomoxetine impaired decision-making and decreased premature responding at all doses tested. Amphetamine also impaired choice performance, but selectively increased impulsive action in rats that had previously received atomoxetine treatment during adolescence. These findings contribute to our understanding of the long-term effects associated with chronic adolescent atomoxetine exposure and suggest that this treatment does not alter decision-making under conditions of risk and uncertainty in adulthood.

Background Contralateral prophylactic mastectomy (CPM) rates have been increasing in the U.S. Though some studies have reported high overall satisfaction among women who undergo CPM, it is unclear how long-term satisfaction differs from that of women who undergo unilateral mastectomy (UM). Furthermore, few studies have assessed whether the effects of CPM on body image differ from those of breast conserving surgery (BCS) or UM. Methods We analyzed responses from a survey of women with both a personal and family history of breast cancer who were enrolled in the Sister Study (n=1176). Among women who underwent mastectomy, satisfaction with mastectomy decision and reconstruction was compared between women who underwent CPM and UM. We also evaluated responses on 5 items related to body image according to surgery type (BCS, UM without reconstruction, CPM without reconstruction, UM with reconstruction, and CPM with reconstruction). Results Participants were, on average, 60.8 years old at diagnosis (SD=8.7) and 3.6 years post-diagnosis at the time of survey (SD=1.7). BCS was the most common surgical treatment reported (63%), followed by CPM (22%) and UM (15%). Satisfaction with mastectomy decision was reported by 97% of women who underwent CPM and 89% of those who underwent UM. Compared to other surgery types, women who underwent CPM without reconstruction reported feeling more self-conscious, less feminine, less whole, and less satisfied with the appearance of their breasts. Body image was consistently highest among women who underwent BCS. Conclusions In our sample of women with both a personal and family history of breast cancer, most were highly satisfied with their mastectomy decision, including those who elected to undergo CPM. However, body image was lowest among women who underwent CPM without reconstruction. Our findings may inform decisions among women considering various courses of surgical treatment. PMID:28058563

Treatment options in Graves' disease are clearly defined, but management practices and the perceptions of success are varied. The outcomes of treatment in large consecutive cohorts of Graves' disease have not been well characterised. The study describes the epidemiology, management strategies and medium term outcomes following anti-thyroid drug treatment, radio-iodine ablation and surgery in Graves' disease. All patients (n = 659) who received treatment for a new diagnosis of Graves' disease in secondary care over a 5 year period were included with a median (interquartile range) follow-up of 42.9 (29-57.5) months. The age adjusted incidence of adult onset Graves' disease in Sheffield, UK was 24.8 per 100,000 per year. Excluding 35 patients lost to follow-up, 93.1% (n = 581) were controlled on anti-thyroid drug treatment. Of these, 73.6% went into remission following withdrawal of anti-thyroid drugs; 5.2% were still undergoing initial therapy; 13.3% lost control whilst on anti-thyroid drugs; and 7.9% went on to have either surgery or radio-iodine ablation whilst controlled on anti-thyroid drugs. Of the 428 patients who achieved remission, 36.7% relapsed. Of 144 patients who had radio-iodine ablation treatment, 5.6% relapsed and needed further treatment. Of 119 patients having surgery, 5.2% had long-term hypoparathyroidism and none had documented long-term recurrent laryngeal nerve palsy. In the follow-up, 39.9% of patients underwent surgery or radio-iodine ablation with little morbidity. Up to two-thirds of patients who achieved remission did not relapse. Data on effectiveness and risks of treatments for Graves' disease presented in this study will help clinicians and patients in decision making.

Although surgical resection is the only curative strategy for pancreatic cancer, the prognosis of patients with pancreatic cancer remains poor. Recently, neoadjuvant treatment has been frequently employed as a promising treatment. Here, the mid-term results of neoadjuvant chemoradiotherapy(NACRT)using S-1, which has been performed in our hospital since 2008, are reported. Seventy-nine patients with resectable or borderline resectable pancreatic ductal adenocarcinoma, who had been intended to undergo NACRT treatment using S-1, were enrolled. The NACRT comprised radiotherapy( 1.8 Gy×28 days)and full-dose twice-daily oral S-1 given on the same days as the radiotherapy. The results of the NACRT and pancreatectomy and the patients' prognoses were evaluated. Fifty-five patients(69.6%)underwent pancreatectomy, with no case of mortality. The curative resection rate was 94.5%. Postoperative adjuvant chemotherapy was administered in 46 patients(83.6%). The 3-year survival rates of all 79 patients and 55 pancreatectomy patients were 40.1% and 50.4%, respectively. NACRT using S-1 was found to be feasible, and good mid-term outcomes were obtained. However, analysis of the long-term outcomes and comparisons with other novel anti-cancer drugs are still required.

Many patients with spasmodic dysphonia (SD) see consistent effects from botulinum toxin (BTX) injections of the same dose, whereas others require dosage changes over time. We sought to determine whether demographics (age and gender) or environmental factors (smoking) affect the long-term stability of BTX dosing in these patients. Retrospective review. Charts of all patients undergoing BTX injection for adductor SD were reviewed. Dosage change, defined as whether there was any difference in total dosage used between two beneficial injections, was used as a measure of dosing stability. Beneficial injections were indicated by a voice rating score of at least three of four and any non-zero duration of improved voice. Logistic regression analysis was performed to determine whether age, gender, smoking status, or duration of treatment correlated with odds of having a dosage change. A total of 211 patients were ultimately included. Age, gender, and smoking status were all found to have no correlative effect on dosing stability. The only factor that was predictive of dose stability was the number of previous beneficial injections, as every additional injection led to decreased odds of a change in dosage for the next injection (odds ratio=0.964; 95% confidence interval=0.947-0.981). Dosage of BTX injections for long-term treatment of SD has a significant propensity to remain stable over time. Factors such as age, gender, and smoking status do not appear to influence the dosage stability. These findings should allow for better patient counseling regarding expectations for their long-term treatment. Copyright © 2015 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

We update Radiation Therapy Oncology Group trial 8911 (USA Intergroup 113), a comparison of chemotherapy plus surgery versus surgery alone for patients with localized esophageal cancer. The relationship between resection type and between tumor response and outcome were also analyzed. The chemotherapy group received preoperative cisplatin plus fluorouracil. Outcome based on the type of resection (R0, R1, R2, or no resection) was evaluated. The main end point was overall survival. Disease-free survival, relapse pattern, the influence of postoperative treatment, and the relationship between response to preoperative chemotherapy and outcome were also evaluated. Two hundred sixteen patients received preoperative chemotherapy, 227 underwent immediate surgery. Fifty-nine percent of surgery only and 63% of chemotherapy plus surgery patients underwent R0 resections (P = .5137). Patients undergoing less than an R0 resection had an ominous prognosis; 32% of patients with R0 resections were alive and free of disease at 5 years, only 5% of patients undergoing an R1 resection survived for longer than 5 years. The median survival rates for patients with R1, R2, or no resections were not significantly different. While, as initially reported, there was no difference in overall survival for patients receiving perioperative chemotherapy compared with the surgery only group, patients with objective tumor regression after preoperative chemotherapy had improved survival. For patients with localized esophageal cancer, whether or not preoperative chemotherapy is administered, only an R0 resection results in substantial long-term survival. Even microscopically positive margins are an ominous prognostic factor. After a R1 resection, postoperative chemoradiotherapy therapy offers the possibility of long-term disease-free survival to a small percentage of patients.

Objective Describe the surgical technique, complications and long term outcomes of total pancreatectomy and islet auto transplantation (TP-IAT) in a large series of pediatric patients. Summary Background Data Surgical management of childhood pancreatitis is not clear; partial resection or drainage procedures often provide transient pain relief, but long term recurrence is common due to the diffuse involvement of the pancreas. Total pancreatectomy (TP) removes the source of the pain, while islet auto transplantation (IAT) potentially can prevent or minimize TP-related diabetes. Methods Retrospective review of 75 children undergoing TP-IAT for chronic pancreatitis who had failed medical, endoscopic or surgical treatment between 1989–2012. Results Pancreatitis pain and the severity of pain statistically improved in 90% of patients after TP-IAT (p =<0.001). The relief from narcotics was sustained. Of the 75 patients undergoing TP-IAT, 31 (41.3%) achieved insulin independence. Younger age (p=0.032), lack of prior Puestow (p=0.018), lower body surface area (p=0.048), IEQ per Kg Body Weight (p=0.001) and total IEQ (100,000) (0.004) were associated with insulin independence. By multivariate analysis, 3 factors were associated with insulin independence after TP-IAT:(1) male gender, (2) lower body surface area and the (3) higher total IEQ per kilogram body weight. Total IEQ (100,000) was the single factor most strongly associated with insulin independence (OR = 2.62; p value < 0.001). Conclusions TP-IAT provides sustained pain relief and improved quality of life. The β cell function is dependent on islet yield. TP-IAT is an effective therapy for children with painful pancreatitis that fail medical and or endoscopic management PMID:24509206

The clinical aspects of patients with hepatocellular carcinoma (HCC) undergoing maintenance dialysis are largely unknown. We aimed to investigate the long-term survival and prognostic determinants of dialysis patients with HCC. A total of 2502 HCC patients, including 30 dialysis patients and 90 age, sex, and treatment-matched controls were retrospectively analyzed. Dialysis patients more often had dual viral hepatitis B and C, lower serum α-fetoprotein level, worse performance status, higher model for end-stage liver disease (MELD) score than non-dialysis patients and matched controls (P all < 0.05). There was no significant difference in long-term survival between dialysis and non-dialysis patients and matched controls (P = 0.684 and 0.373, respectively). In the Cox proportional hazards model, duration of dialysis < 40 months (hazard ratio [HR]: 6.67, P = 0.019) and ascites (HR: 5.275, P = 0.019) were independent predictors of poor prognosis for dialysis patients with HCC. Survival analysis disclosed that the Child-Turcotte-Pugh (CTP) provided a better prognostic ability than the MELD system. Among the four currently used staging systems, the Japan Integrated Scoring (JIS) system was a more accurate prognostic model for dialysis patients; a JIS score ≥ 2 significantly predicted a worse survival (P = 0.024). Patients with HCC undergoing maintenance dialysis do not have a worse long-term survival. A longer duration of dialysis and absence of ascites formation are associated with a better outcome in dialysis patients. The CTP classification is a more feasible prognostic marker to indicate the severity of cirrhosis, and the JIS system may be a better staging model for outcome prediction. © 2012 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Clinical guidelines recommend at least 3-months low molecular weight heparin (LMWH) treatment for established venous thromboembolism (VTE) in cancer patients. However, no study has analyzed the impact of 3-6 months of LMWH therapy on quality-of-life (QoL) in cancer patients. Among 400 cancer patients included at M0, 88.8% received long-term LMWH. Using a random-effects linear regression model with time as covariate, QoL scores in the MOS SF-36 (Global HRQoL, 1.3-fold per month [95% confidence interval (CI) 0.81-1.79], p < 0.0001) and EORTC QLQ-C30 (global health status/qol, 2.25-fold per month [95% CI 1.63-2.88]; p < 0.0001) questionnaires significantly improved over the 6-month study period in patients treated with LMWH, while VEINES-QOL scores did not change. In the MOS SF-36 and EORTC QLQ-C30, the following factors were associated with change in QoL: symptomatic VTE, cancer dissemination and histological type. Factors pertaining to reduced mobility were also identified as significant predictors of QoL outcomes, including being bedridden in the MOS SF-36 and ECOG score ≥ 2 in the EORTC QLQ-C30. Presence of acute infection and not undergoing anti-angiogenic therapy were additional factors associated with QoL improvement in the EORTC QLQ-C30. QUAVITEC, a prospective, longitudinal, multicenter study, recruited all consecutive eligible adult cancer patients with objectively confirmed VTE between February 2011 and 2012. Patients were asked to answer three QoL questionnaires at anticoagulant treatment initiation (M0) and at 3 (M3) and 6 (M6)-month follow-ups. QUAVITEC is the first study to show that QoL was improved in cancer patients receiving long-term LMWH treatment for established VTE.

Superstition is common and causes discomfiture or fear, especially in patients who have to undergo surgery for cancer. One superstition is, that moon phases influence surgical outcome. This study was performed to analyse lunar impact on the outcome following lung cancer surgery. 2411 patients underwent pulmonary resection for lung cancer in the past 30 years at our institution. Intra- and postoperative complications as well as long-term follow-up data were entered in our lung-cancer database. Factors influencing mortality, morbidity and survival were analyzed. Rate of intra-operative complications as well as rate of post-operative morbidity and mortality was not significantly affected by moon phases. Furthermore, there was no significant impact of the lunar cycle on long-term survival. In this study there was no evidence that outcome of surgery for lung cancer is affected by the moon. These results may help the physician to quiet the mind of patients who are somewhat afraid of wrong timing of surgery with respect to the moon phases. However, patients who strongly believe in the impact of moon phase should be taken seriously and correct timing of operations should be conceded to them as long as key-date scheduling doesn't constrict evidence based treatment regimens.

To examine the impact of re-entry device (RED) use on 1- and 5-year outcomes after endovascular treatment of common iliac artery (CIA) chronic total Occlusions (CTOs). There are not enough data regarding the long-term safety and efficacy of RED. We performed a two-center retrospective study of 115 patients (140 lesions) undergoing CIA CTO endovascular intervention between 2006 and 2016. Baseline characteristics and long-term outcomes were described. A Cox proportional hazard model was developed to determine if REDs were associated with target lesion revascularization (TLR) or major adverse limb events (MALE) after 1 and 5 years. Among 140 lesions, 43 (31%) required use of a RED. The mean age was 63.9 years and the majority (n = 80) of patients were male. An antegrade crossing approach and treatment of restenotic lesions were less common in the RED group (10% vs. 29%, P < .05 and 0% vs. 21%, P < .05, respectively). There were no significant differences in Rutherford class, pre-procedure ABI, or patient presentation. The procedural complication rates were similar between the two groups. The 1- and 5-year TLR rates for lesions treated with re-entry device vs. standard approaches were 11% vs. 9%; P = 0.8 and 29% vs. 29%; P = 0.9 respectively. The 1 and 5-year MALE rates for lesions treated with re-entry device were 5% vs. 6%; P = 0.8 and 11% vs. 11%; P = 0.9 respectively. This retrospective analysis found that recanalization of CIA occlusions using a RED is safe and is associated with long-term clinical outcomes similar to that of standard crossing techniques. © 2018 Wiley Periodicals, Inc.

To compare perioperative outcomes for patients undergoing holmium laser enucleation of the prostate (HoLEP) and robotic-assisted simple prostatectomy (RSP) for benign prostatic hypertrophy (BPH). Patient demographics and perioperative outcomes were compared between 600 patients undergoing HoLEP and 32 patients undergoing RSP at two separate academic institutions between 2008 and 2015. Patients undergoing HoLEP and RSP had comparable ages (71 vs 71, p = 0.96) and baseline American Urological Association Symptom Scores (20 vs 24, p = 0.21). There was no difference in mean specimen weight (96 g vs 110 g, p = 0.15). Mean operative time was reduced in the HoLEP cohort (103 minutes vs 274 minutes, p < 0.001). Patients undergoing HoLEP had lesser decreases in hemoglobin, decreased transfusions rates, shorter hospital stays, and decreased mean duration of catheterization. There was no difference in the rate of complications Clavien grade 3 or greater (p = 0.33). HoLEP and RSP are both efficacious treatments for large gland BPH. In expert hands, HoLEP appears to have a favorable perioperative profile. Further studies are necessary to compare long-term efficacy, cost, and learning curve influences, especially as minimally invasive approaches become more widespread.

Role of salvage esophagectomy after definitive chemoradiotherapy.

2009-02-01

Chemoradiotherapy has become a popular definitive therapy among many patients and oncologists for potentially resectable esophageal carcinoma. Although the complete response rates are high and short-term survival is favorable after chemoradiotherapy, persistent or recurrent locoregional disease is quite frequent. Salvage surgery is the sole curative intent treatment option for this course. As experience with definitive chemoradiotherapy grows, the number of salvage surgeries may increase. Selected articles about salvage esophagectomy after definitive chemoradiotherapy for esophageal carcinoma are reviewed. The number of salvage surgeries was significantly lower than the number of expected candidates. To identify candidates for salvage surgery, patients undergoing definitive chemoradiotherapy should be followed up carefully. Salvage esophagectomy is difficult when dissecting fibrotic masses from irradiated tissues. Patients who underwent salvage esophagectomy had increased morbidity and mortality. Pulmonary complications such as pneumonia and acute respiratory distress syndrome were common. The anastomotic leak rate was significantly increased because of the effects of the radiation administered to the tissues used as conduits. The most significant factor associated with long-term survival appeared to be complete resection. However, precise evaluation of resectability before operation was difficult. Nevertheless, increased morbidity and mortality will be acceptable in exchange for potential long-term survival after salvage esophagectomy. Such treatment should be considered for carefully selected patients at specialized centers.

Timing of angiography with a routine invasive strategy and long-term outcomes in non-ST-segment elevation acute coronary syndrome: a collaborative analysis of individual patient data from the FRISC II (Fragmin and Fast Revascularization During Instability in Coronary Artery Disease), ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes), and RITA-3 (Intervention Versus Conservative Treatment Strategy in Patients With Unstable Angina or Non-ST Elevation Myocardial Infarction) Trials.

This study sought to investigate long-term outcomes after early or delayed angiography in patients with non-ST-segment elevation acute coronary syndrome (nSTE-ACS) undergoing a routine invasive management. The optimal timing of angiography in patients with nSTE-ACS is currently a topic for debate. Long-term follow-up after early (within 2 days) angiography versus delayed (within 3 to 5 days) angiography was investigated in the FRISC-II (Fragmin and Fast Revascularization During Instability in Coronary Artery Disease), ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes), and RITA-3 (Intervention Versus Conservative Treatment Strategy in Patients With Unstable Angina or Non-ST Elevation Myocardial Infarction) (FIR) nSTE-ACS patient-pooled database. The main outcome was cardiovascular death or myocardial infarction up to 5-year follow-up. Hazard ratios (HR) were calculated with Cox regression models. Adjustments were made for the FIR risk score, study, and the propensity of receiving early angiography using inverse probability weighting. Of 2,721 patients originally randomized to the routine invasive arm, consisting of routine angiography and subsequent revascularization if suitable, 975 underwent early angiography and 1,141 delayed angiography. No difference was observed in 5-year cardiovascular death or myocardial infarction in unadjusted (HR: 1.06, 95% confidence interval [CI]: 0.79 to 1.42, p=0.61) and adjusted (HR: 0.93, 95% CI: 0.75 to 1.16, p=0.54) Cox regression models. In the FIR database of patients presenting with nSTE-ACS, the timing of angiography was not related to long-term cardiovascular mortality or myocardial infarction.

The primary goals of long-term disease management in non-cystic fibrosis bronchiectasis (NCFB) are to reduce the number of exacerbations, and improve quality of life. However, currently no therapies are licensed for this. Ciprofloxacin Dry Powder for Inhalation (Ciprofloxacin DPI) has potential to be the first long-term intermittent therapy approved to reduce exacerbations in NCFB patients. The RESPIRE programme consists of two international phase III prospective, parallel-group, randomized, double-blinded, multicentre, placebo-controlled trials of the same design. Adult patients with idiopathic or post-infectious NCFB, a history of ≥2 exacerbations in the previous 12months, and positive sputum culture for one of seven pre-specified pathogens, undergo stratified randomization 2:1 to receive twice-daily Ciprofloxacin DPI 32.5mg or placebo using a pocket-sized inhaler in one of two regimens: 28days on/off treatment or 14days on/off treatment. The treatment period is 48weeks plus an 8-week follow-up after the last dose. The primary efficacy endpoints are time to first exacerbation after treatment initiation and frequency of exacerbations using a stringent definition of exacerbation. Secondary endpoints, including frequency of events using different exacerbation definitions, microbiology, quality of life and lung function will also be evaluated. The RESPIRE trials will determine the efficacy and safety of Ciprofloxacin DPI. The strict entry criteria and stratified randomization, the inclusion of two treatment regimens and a stringent definition of exacerbation should clarify the patient population best positioned to benefit from long-term inhaled antibiotic therapy. Additionally RESPIRE will increase understanding of NCFB treatment and could lead to an important new therapy for sufferers. The RESPIRE trials are registered in ClinicalTrials.gov, ID number NCT01764841 (RESPIRE 1; date of registration January 8, 2013) and NCT02106832 (RESPIRE 2; date of registration April 4, 2014).

Ingadóttir, Thorbjorg Sóley; Jonsdottir, Helga

2006-03-01

Technological dependency is defined as a short or long-term reliance on machines and techniques to evaluate, satisfy or resolve health problems. In nursing technological dependency has been explored in the context of caring. Hitherto it has been maintained that technology and caring are contradictory, but a more prominent view is that technology and caring can and must be reconciled to provide high-quality care. This study describes patients' and families' experience of long-term home treatment with noninvasive ventilation during sleep with or without additional oxygen therapy. Considering the potential burden of undergoing this treatment the research question is: What is patients' and families' experience of being dependent on technical breathing assistance during sleep? The methodological approach draws from interpretive phenomenology and narrative analysis. Participants were six patients aged 45-70, five spouses and one daughter. Data, generated through two 1-hour semi-structured interviews with each pair of participants, were analysed into themes. Results are presented by the following narratives: (i) mixed blessing: life-saving treatment - meaningless exertion; (ii) compassion and understanding central amid use of complex machines; (iii) listening to the body; (iv) wanting to be seen as healthy; (v) dominance of technological thinking; and (vi) sustained work in maintaining the treatment. It is concluded that being dependent on technical breathing assistance during sleep, with or without oxygen, was a major life event for participants. The treatment was experienced as constraining and intrusive, particularly at the beginning, but concurrently it dramatically relieved difficulties for most participants. Regardless of its usefulness it provoked questions on purpose, indicating that the way to implement the treatment is crucial. Professionals need to pay close attention to how they introduce noninvasive ventilation technique, putting caring concern and respect for unique needs of patients and their families at the forefront.

Background: Umbilical hernias are common in patients with end-stage liver disease undergoing liver transplantation. Management of those persisting at the time of liver transplantation is important to define. Objective: To evaluate the long-term results of patients undergoing simultaneous primary umbilical hernia repair (UHR) at the time of liver transplantation at a single institution. Methods: Retrospective chart review was performed on patients undergoing simultaneous UHR and liver transplantation from 2010 through 2016. 30-day morbidity and mortality outcomes and long-term hernia recurrence were investigated. Results: 59 patients had primary UHR at the time of liver transplantation. All hernias were reducible with no overlying skin breakdown or leakage of ascites. 30-day morbidity and mortality included 5 (8%) superficial surgical site infections, 1 (2%) deep surgical site infection, and 7 (12%) organ space infections. Unrelated to the UHR, 10 (17%) patients had an unplanned return to the operating room, 16 (27%) were readmitted within 30 days of their index operation, and 1 (2%) patient died. With a mean follow-up of 21.8 months, 7 (18%) patients experienced an umbilical hernia recurrence. Conclusion: Despite the high perioperative morbidity associated with the transplant procedure, concurrent primary UHR resulted in an acceptable long-term recurrence rate with minimal associated morbidity.

Patients who undergo laryngectomy typically lose their sense of smell. One device that has been used to rehabilitate olfactory function in these patients is the larynx bypass. We conducted a long-term study of the larynx bypass in 16 laryngectomized patients. After undergoing objective and subjective baseline evaluations, patients were asked to use the device at home for at least 30 minutes each day for 3 months. They were also asked to record in a diary subjective ratings of their sense of smell and the practicability of using the device every day. At study's end, patients experienced a statistically significant improvement (p < 0.001) in olfactory function on objective measurement (Sniffin' Sticks testing). Subjective improvement was seen after 1 week (p < 0.001) and maintained throughout the study. Practicability scores improved statistically (p = 0.003), but the device remained difficult to use. The long-term use of the larynx bypass has not been studied previously, and we hope that our findings will serve as a basis for further investigation.

Multiple mechanisms of serotonin 5-HT2 receptor desensitization.

Rahman, S; Neuman, R S

Desensitization of serotonin 5-HT2 receptor-mediated enhancement of the N-methyl-D-aspartate (NMDA) depolarization was studied in rat cortical neurons. Serotonin and (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) induced long term desensitization. Staurosporine, a nonspecific protein kinase C inhibitor, potentiated the serotonin and DOI facilitation, suggesting acute desensitization was operative. In the case of DOI, long term desensitization was prevented by staurosporine. Activators of protein kinase C abolished the serotonin facilitation, an action prevented by staurosporine. Concanavalin A potentiated the facilitation at 100 microM, but not 30 microM serotonin, suggesting these receptors undergo dose dependent internalization. Calmodulin antagonists prevent long term desensitization induced by serotonin. The depolarization induced by NMDA alone was not altered by staurosporine, protein kinase C activators, concanavalin A or calmodulin antagonists. Serotonin at 100 microM, but not 30 microM, induced heterologous desensitization of phenylephrine and carbachol induced facilitation of the NMDA depolarization. We conclude that serotonin 5-HT2 receptors both induce and undergo several forms of desensitization.

Limited data are available about the challenges of non-national TB patients undergoing long-term treatment courses in an urban setting. This study aimed to understand the financial and social cost of adherence of non-national TB patients in Cairo, Egypt as a means to inform the development of context-specific interventions to support treatment adherence. In 2011, 22 in-depth interviews were conducted with TB patients from Sudan, Ethiopia, Eritrea, Somalia and Djibouti to obtain qualitative data. Analysis was based on thematic analysis that aimed to identify recurrent themes and codes from the narratives. The study identified a number of factors that influence TB treatment adherence. Uncertain financial status due to limited or no employment was frequently discussed in interviews, which resulted in fear of not being able to support family, loss of pride, dependence on family and friends, fear of losing housing, food insecurity and limited food options. Respondents also feared infecting other household members and longed for opportunities to discuss their illness and treatment experiences with other individuals but their social networks were often limited. TB-related stigma was driven by shame and blame of infection. Respondents also believed stigma was based on their foreign origin. Stigma manifested in distancing and exclusion in various ways, resulting in isolation, psychological distress and reluctance to disclose TB status to others. Poverty-related factors and social context with a special focus on stigma should be considered when developing strategies for supporting long-term treatment courses for non-national patients in Cairo and other similar urban settings. © 2015 John Wiley & Sons Ltd.

Lung volume reduction surgery for emphysema.

PubMed

Flaherty, K R; Martinez, F J

2000-12-01

Over the past decades, extensive literature has been published regarding surgical therapies for advanced COPD. Lung-volume reduction surgery would be an option for a significantly larger number of patients than classic bullectomy or lung transplantation. Unfortunately, the initial enthusiasm has been tempered by major questions regarding the optimal surgical approach, safety, firm selection criteria, and confirmation of long-term benefits. In fact, the long-term follow-up reported in patients undergoing classical bullectomy should serve to caution against unbridled enthusiasm for the indiscriminate application of LVRS. Those with the worst long-term outcome despite favourable short-term improvements after bullectomy have consistently been those with the lowest pulmonary function and significant emphysema in the remaining lung who appear remarkably similar to those being evaluated for LVRS. With this in mind, the National Heart, Lung and Blood Institute partnered with the Health Care Finance Administration to establish a multicenter, prospective, randomized study of intensive medical management, including pulmonary rehabilitation versus the same plus bilateral (by MS or VATS), known as the National Emphysema Treatment Trial. The primary objectives are to determine whether LVRS improves survival and exercise capacity. The secondary objectives will examine effects on pulmonary function and HRQL, compare surgical techniques, examine selection criteria for optimal response, identify criteria to determine those who are at prohibitive surgical risk, and examine long-term cost effectiveness. It is hoped that data collected from this novel, multicenter collaboration will place the role of LVRS in a clearer perspective for the physician caring for patients with advanced emphysema.

The purpose of this study was to predict the poor and excessive ovarian response using anti-Müllerian hormone (AMH) levels following a long agonist protocol in IVF candidates. Through a prospective cohort study, the type of relationship and appropriate scale for AMH were determined using the fractional polynomial regression. To determine the effect of AMH on the outcomes of ovarian stimulation and different ovarian responses, the multi-nominal and negative binomial regression models were fitted using backward stepwise method. The ovarian response of study subject who entered a standard long-term treatment cycle with GnRH agonist was evaluated using prediction model, separately and in combined models with (ROC) curves. The use of standard long-term treatments with GnRH agonist led to positive pregnancy test results in 30% of treated patients. With each unit increase in the log of AMH, the odds ratio of having poor response compared to normal response decreases by 64% (OR 0.36, 95% CI 0.19-0.68). Also the results of negative binomial regression model indicated that for one unit increase in the log of AMH blood levels, the odds of releasing an oocyte increased 24% (OR 1.24, 95% CI 1.14-1.35). The optimal cut-off points of AMH for predicting excessive and poor ovarian responses were 3.4 and 1.2 ng/ml, respectively, with area under curves of 0.69 (0.60-0.77) and 0.76 (0.66-0.86), respectively. By considering the age of the patient undergoing infertility treatment as a variable affecting ovulation, use of AMH levels showed to be a good test to discriminate between different ovarian responses.

In the present study, twenty-five samples of red blood cells (RBCs) and two samples of lyophilized serum, drawn from thirteen patients with Β-thanassemia major, have been examined by Mössbauer spectroscopy. All these patients undergo long-term therapy by regular blood transfusion and deferoxamine. The samples were obtained at the end of one cycle of treatments, before the successive blood transfusion. The results show, within the experimental errors, that the ferritin-like iron appears to be absent in the RBCs of the patients but it is still present in the serum.

Severe aplastic anemia (SAA) patients receive more red blood cell (RBC) transfusions as supportive management. We aim to clarify the associations between transfusion history or pre-transplantation serum ferritin (SF) and the overall survival of allogeneic hematopoietic stem cell transplantation (allo-HSCT) among SAA patients. We retrospectively investigated 96 SAA patients undergoing allo-HSCT, and grouped them according to pre-transplantation duration. Pre-transplantation SF, transfused units and other iron-related parameters were collected. Comparisons in transplantation outcomes and complications were made in groups with different SF levels and different transfusion histories. Among the 96 SAA patients, 45 patients received transplantation within 2 months after diagnosis (short-term pre-transplantation period), and the rest of the patients had long-term pre-transplantation treatment. Among the patients with short-term pre-transplantation treatment, a higher risk of death was seen in the high-ferritin group (p < 0.05). Elevated SF also predicted a trend in incidence of higher bloodstream infection (p = 0.108). Significant correlations were observed between pre-transplantation SF and infection incidence, as well as transfusion history. However, for patients with longer pre-transplantation duration, transfusion history was associated with worse outcome (p = 0.026), in terms of higher incidence of acute graft versus host disease (p = 0.048). High SF was only significantly associated with prolonged RBC transfusion dependence post-transplantation (p = 0.044). Transfusion history was a stronger predictor of outcome than SF in patients undergoing transplantation more than 2 months after diagnosis.

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the current gold standard in the surgical treatment of ulcerative colitis (UC) refractory to medical management. A procedure of significant magnitude carries its own risks including anastomotic failure, pelvic sepsis and a low rate of neoplastic degeneration overtime. Recent studies have shown that total colectomy with ileorectal anastomosis (IRA) has been associated with good long-term functional results in a selected group of UC patients amenable to undergo a strict surveillance for the relatively high risk of cancer in the rectum. This manuscript will review and compare the most recent literature on IRA and IPAA as it pertains to postoperative morbidity and mortality, failure rates, functional outcomes and cancer risk.

Short-Term Plasticity and Long-Term Potentiation in Magnetic Tunnel Junctions: Towards Volatile Synapses

Sengupta, Abhronil; Roy, Kaushik

2016-02-01

Synaptic memory is considered to be the main element responsible for learning and cognition in humans. Although traditionally nonvolatile long-term plasticity changes are implemented in nanoelectronic synapses for neuromorphic applications, recent studies in neuroscience reveal that biological synapses undergo metastable volatile strengthening followed by a long-term strengthening provided that the frequency of the input stimulus is sufficiently high. Such "memory strengthening" and "memory decay" functionalities can potentially lead to adaptive neuromorphic architectures. In this paper, we demonstrate the close resemblance of the magnetization dynamics of a magnetic tunnel junction (MTJ) to short-term plasticity and long-term potentiation observed in biological synapses. We illustrate that, in addition to the magnitude and duration of the input stimulus, the frequency of the stimulus plays a critical role in determining long-term potentiation of the MTJ. Such MTJ synaptic memory arrays can be utilized to create compact, ultrafast, and low-power intelligent neural systems.

Lymph node (LN) involvement by esophageal cancer is associated with compromised long-term prognosis. This study assessed whether LN downstaging by neoadjuvant treatment (NAT) might offer a survival benefit compared to patients with a priori negative LN. Patients undergoing esophagectomy for cancer between 2005 and 2014 were screened for inclusion. Group 1 included cN0 patients confirmed as pN0 who were treated with surgery first, whereas group 2 included patients initially cN+ and down-staged to ypN0 after NAT. Survival analysis was performed with the Kaplan-Meier and Cox regression methods. Fifty-seven patients were included in our study, 24 in group 1 and 33 in group 2. Group 2 patients had more locally advanced lesions compared to a priori negative patients, and despite complete LN sterilization by NAT they still had worse long-term survival. Overall 3-year survival was 86.8% for a priori LN negative versus 63.3% for downstaged patients (P = 0.013), while disease-free survival was 79.6% and 57.9%, respectively (P = 0.021). Tumor recurrence was also earlier and more disseminated for the down-staged group. Downstaged LN, despite the systemic effect of NAT, still inherit an increased risk for early tumor recurrence and worse long-term survival compared to a priori negative LN. © 2017 Wiley Periodicals, Inc.

Tricuspid regurgitation (TR) presents as either primary valve pathology or secondary to pulmonary or left-sided heart disease. Severe TR portends a worse prognosis independent of age, right ventricular size and function, severe left ventricular dysfunction, and increased pulmonary arterial pressures. Surgical treatment for TR has mostly been limited to patients undergoing mitral valve repair since those at high surgical risk are not candidates for traditional TR surgery. For these patients, minimally invasive techniques could be of great benefit, yet these techniques have been slow to develop because of the various anatomic and physiological aspects of the tricuspid valve apparatus. Several promising new techniques are currently undergoing clinical investigation, including caval valve implantation, percutaneous tricuspid annuloplasty techniques (Trialign, TriCinch, Cardioband), edge-to-edge repair with the MitraClip system, the FORMA device, and the GATE tricuspid Atrioventricular Valved Stent. Further evaluation of their safety and long-term efficacy is warranted prior to commercial approval and widespread adoption. PMID:29743996

Biologic therapies have revolutionized the approach to immune-mediated diseases such as psoriasis. Due to their favorable safety profiles and excellent efficacy, biologic agents are considered the gold standard for moderate-to-severe psoriasis. The aim of this paper is to saliently review the severe and acute complications of the Food and Drug Administration (FDA) approved biologic agents for psoriasis. Reviewed agents include tumor necrosis factor alpha inhibitors (etanercept, infliximab, and adalimumab), interleukin 12/23 inhibitors (ustekinumab), and interleukin 17 (IL-17) inhibitors (secukinumab and ixekizumab). While malignancies, serious infections, and major adverse cardiovascular events have been reported, their association with biologic therapy are not hypothesized as causal. However, IL-17 inhibitors appear to cause exacerbations and new cases of inflammatory bowel disease. While more long-term studies are warranted in understanding the biologic's long-term side effect profile, short-term studies have confirmed that the biologics are some of the safest treatment options for psoriasis. Nevertheless, certain populations yield higher risk to acute complications with the biologics than others - physicians must use their judgement and vigilance when monitoring and treating patients undergoing therapy with biological agents.

Recent studies have suggested ABO blood type locus as an inherited predictor of thrombosis, cardiovascular risk factors, myocardial infarction. However, data is scarce about the impact of non-O blood groups on prognosis in patients with ST-elevation myocardial infarction (STEMI). Therefore, we aimed to evaluate the prognostic importance of non-O blood groups in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI) METHODS: 1835 consecutive patients who were admitted with acute STEMI between 2010 and 2015 were included and followed-up for a median of 35.6months. The prevalence of hyperlipidemia, total cholesterol, LDL, peak CKMB and no-reflow as well as hospitalization duration were higher in patients with non-O blood groups. Gensini score did not differ between groups. During the in-hospital and long-term follow-up period, MACE, the prevalence of stent thrombosis, non-fatal MI, and mortality were higher in non-O blood groups. In multivariate logistic regression analysis, non-0 blood groups were demonstrated to be independent predictors of in-hospital (OR:2.085 %CI: 1.328-3.274 p=0.001) and long term MACE (OR:2.257 %CI: 1.325-3.759 p<0.001). Kaplan-Meier analysis according to the long-term MACE free survival revealed a higher occurrence of MACE in non-O blood group compared with O blood group (p<0.001, Chi-square: 22.810). Non-O blood groups were determined to be significant prognostic indicators of short- and long-term cardiovascular adverse events and mortality in patients with STEMI undergoing pPCI. In conjunction with other prognostic factors, evaluation of this parameter may improve the risk categorization and tailoring the individual therapy and follow-up in STEMI patient population.

[The best of valvular heart disease in 2005].

The year 2005 has been rich in publications concerning valvular heart disease. In France, this year has been dominated by the publication of the French Society of Cardiologists' guidelines on the operative and interventional indications for acquired valvular heart disease: discussed and accepted formal indications based on the evidence in the literature. Non-ischaemic mitral insufficiency has been the subject of a major study that showed the high prognostic significance of echographic measuring of the area of the regurgitating orifice; patients with a surface > or =40 mm2 had a worse long-term prognosis and should undergo surgery early. The prognostic significance of BNP in valvular heart disease, such as mitral insufficiency and aortic stenosis, also became apparent. BNP is being used more and more for risk stratification for these conditions. The significance of anti-arrhythmic surgery combined with a mitral procedure has confirmed the harmful effect of atrial fibrillation, before and after the mitral surgery. The first randomised study into the use of statins to slow the progression of aortic stenosis was unfortunately disappointing, despite the various unrandomised studies that had opened a therapeutic pathway for this pathology, for which the prevalence is continually rising due to the ever increasing life expectancy. In mitral stenosis, a randomised study showed the long-term value of mitral commissurotomy in percutaneous mitral valvuloplasty, giving identical long-term results, in terms of mitral area, to those obtained with the classic Inoué balloon. In infectious endocarditis, surveys have confirmed the seriousness of this pathology as well as the slight advances in its prophylaxis. Other studies have confirmed the frequency and the severity of emboli, endocarditis due to Staphylococcus aureus, and the low risk of recurrence for endocarditis with the more and more accepted short course antibiotic treatment for patients undergoing surgery. Of course, this selection of publications is limited and by necessity subjective.

Growth hormone therapy: emerging dilemmas.

The history of pituitary growth hormone (GH) started 100 years ago but the isolation purification and determination of the chemical structure of the human GH (hGH) took another 50 years. Starting in 1957 hGH was extracted from cadaver pituitaries and its clinical use was restricted to severe GH deficient patient. With the invention of recombinant biosynthetic hGH in 1985; the indications for its use were extended. The major approved medications are GH deficiency and short statured children of various etiologies. This is a critical review of present and future use of human GH. To evaluate the effectiveness of the hGH treatment several pharmaceutical companies established postmarketing follow-up programs which are based on the reliability and cooperation of the treating physicians. Unfortunately they stop when the treatment is terminated and most studies refer to growth stimulation effectiveness during initial years but do not follow the children until final height. The long-term experience enabled to evaluate adverse effects (AE), the majority being due to large dosage. The most serious AE reported are increases in malignancies and early or late mortality in adult age. There is consensus that GH deficient children need replacement therapy. As long-term hGH treatment is expensive and the final height gains in non-GH deficient children small the cost-benefit indications to treat short children without a disease has been questioned. To avoid the need of daily injections, long-acting hGH preparations undergo clinical trials. The future will show their effectiveness and eventual adverse effects.

OBJECTIVES Concomitant tricuspid valve surgery with mitral valve surgery is recommended for patients with severe functional tricuspid regurgitation (TR). However, the treatment for 2+ TR (mild TR) remains controversial. Here, we evaluated the long-term results of untreated 2+ TR in patients undergoing mitral valve surgery. METHODS We retrospectively reviewed the records of 96 patients with untreated 2+ TR among 885 patients who underwent mitral valve surgery from 2003 to 2010. Exclusion criteria were tricuspid valve surgery (TVS), emergency surgery, primary TR and pacemaker lead through the tricuspid valve. We assessed survival and freedom from heart failure. The freedom from 3+ (moderate) or 4+ (severe) TR was investigated by echocardiographic data at pre- and postoperative week 1, then at 1, 3, 5, 7 and 10 postoperative years, which were compared with those in patients who had 2+ TR preoperatively and underwent concomitant TVS in the same period (n = 47). RESULTS The mean follow-up was 7.1 ± 2.7 years. There was no 30-day mortality. The survival rate was 97.5% at 5 years and 87.5% at 10 years. The independent risk factors for mortality were age (OR 1.2, P = 0.03) and left ventricular ejection fraction (OR 0.9, P = 0.03). Untreated 2+ TR improved transiently within the first postoperative year (P < 0.001), but progressed again in the mid- to long term. Freedom from ≥3+ TR was 64.2% at 5 years and 46.7% at 10 years, which was significantly lower than that from ≥3+ TR in patients who underwent concomitant TVS (P = 0.006). The independent risk factors for TR progression (≥3 + TR) were age (OR 1.1, P = 0.005), atrial fibrillation (OR 2.2, P = 0.04) and tricuspid annular diameter (TAD) index (mm/m2; OR 1.1, P = 0.02). Receiver operating characteristic curves showed that the optimal TAD index cut-off value was 21.0 for long-term survival [area under the curve (AUC) = 0.72] and 21.2 for TR progression (AUC = 0.64). CONCLUSIONS Although untreated, 2+ TR significantly improved after mitral valve surgery, it then progressed again in the mid- to long term. Therefore, concomitant TVS should be considered in patients with 2+ TR who have dilated tricuspid annulus or atrial fibrillation, if feasible. PMID:26993477

The Pain System in Oesophageal Disorders: Mechanisms, Clinical Characteristics, and Treatment

PubMed Central

Lottrup, Christian; Olesen, Søren Schou; Drewes, Asbjørn Mohr

2011-01-01

Pain is common in gastroenterology. This review aims at giving an overview of pain mechanisms, clinical features, and treatment options in oesophageal disorders. The oesophagus has sensory receptors specific for different stimuli. Painful stimuli are encoded by nociceptors and communicated via afferent nerves to the central nervous system. The pain stimulus is further processed and modulated in specific pain centres in the brain, which may undergo plastic alterations. Hence, tissue inflammation and long-term exposure to pain can cause sensitisation and hypersensitivity. Oesophageal sensitivity can be evaluated ,for example, with the oesophageal multimodal probe. Treatment should target the cause of the patient's symptoms. In gastro-oesophageal reflux diseases, proton pump inhibitors are the primary treatment option, surgery being reserved for patients with severe disease resistant to drug therapy. Functional oesophageal disorders are treated with analgesics, antidepressants, and psychological therapy. Lifestyle changes are another option with less documentation. PMID:21826137

To evaluate the long-term functional recovery and health-related quality of life (HRQOL) in patients after surgically treated putaminal hemorrhages. Surgery for putaminal hemorrhages remains a controversial issue. Although numerous reports describe conflictive results regarding short-term outcome of surgically treated patients, very little is known about their long-term recovery and their HRQOL. In this monocentric, retrospective study we analyzed mortality, long-term functional outcome, activity of daily life status, and HRQOL undergoing craniotomy for hematoma evacuation between December 2004 and January 2011. Forty-nine consecutive patients were identified with 8 (16.3%) patients dying during acute care. Forty-one patients surviving acute phase were transferred to neurologic rehabilitation hospitals. One patient was lost to follow-up. Median follow-up was 52.9 (17-101) months. At follow-up, 24 of 40 (60%) patients still were alive with 16 of 40 (40%) patients living with major disability (modified Rankin Scale [mRS], 4 or 5). Seven patients (17.5%) showed a mRS lesser than or equal to 3 with only 3 (7.5%) of those living functionally independent (mRS, 0-2). HRQOL in survivors was reduced with a median DEMQOL/DEMQOL (a patient/caregiver reported outcome measure designed to assess health-related quality of life of people with dementia) proxy score of 92 and 93, respectively. All patients showed severe impairment in activities of daily life. This is the first long-term follow-up analysis for patients with surgically treated putaminal hemorrhages. Survivors show only marginal recovery despite intensive neurologic rehabilitation; most remain dependent with a reduced HRQOL and significantly impaired activities of daily life status.

Phosphorus (P) is closely linked to major societal concerns including food security and water quality, and human activities strongly control the modern global P cycle. Current knowledge of the P cycle includes many insights about relatively short-term processes, but a long-term and landscape-level view may be needed to understand P status and optimize P management towards P sustainability. We reconstructed long-term (>40 years) P mass balances and rates of P accumulation in three major river basins where excess P pollution is demanding improvements in P management at local, national, and international levels. We focus on: Maumee River Basin, a major source of agricultural P to Lake Erie, the southernmost and shallowest of the Laurentian Great Lakes; Thames River Basin, where fluxes of effluent P from the London, England metropolitan area have declined following improvements in wastewater treatment; Yangtze (Changjiang) River Basin, the largest in China, which is undergoing rapid economic development. The Maumee and Thames are intensively monitored, and show long-term declines in basin P inputs that represent a step towards P sustainability. However, river P outputs have been slower to decline, consistent with the hypothesis that legacy P is mobilizing from soils or from within the river network. Published data on the Yangtze indicate the P flux from land to water has clearly increased with industrialization and population growth. Historical trajectories of P accumulation and depletion in major river basins are providing new understanding about the long-term impacts of P management, including watershed P legacies and response times, that may inform future policy towards local, national, and global P sustainability.

Bariatric surgery is a well-documented treatment for obesity, but there are uncertainties about the degree to which such surgery is associated with health care cost reductions that are sustained over time. To provide a comprehensive, multiyear analysis of health care costs by type of procedure within a large cohort of privately insured persons who underwent bariatric surgery compared with a matched nonsurgical cohort. Longitudinal analysis of 2002-2008 claims data comparing a bariatric surgery cohort with a matched nonsurgical cohort. Seven BlueCross BlueShield health insurance plans with a total enrollment of more than 18 million persons. A total of 29 820 plan members who underwent bariatric surgery between January 1, 2002, and December 31, 2008, and a 1:1 matched comparison group of persons not undergoing surgery but with diagnoses closely associated with obesity. Standardized costs (overall and by type of care) and adjusted ratios of the surgical group's costs relative to those of the comparison group. Total costs were greater in the bariatric surgery group during the second and third years following surgery but were similar in the later years. However, the bariatric group's prescription and office visit costs were lower and their inpatient costs were higher. Those undergoing laparoscopic surgery had lower costs in the first few years after surgery, but these differences did not persist. Bariatric surgery does not reduce overall health care costs in the long term. Also, there is no evidence that any one type of surgery is more likely to reduce long-term health care costs. To assess the value of bariatric surgery, future studies should focus on the potential benefit of improved health and well-being of persons undergoing the procedure rather than on cost savings.

Long-Term Safety of Letrozole and Gonadotropin Stimulation for Fertility Preservation in Women With Breast Cancer

2016-01-01

Context and Objective: There has been increased attention to the issue of fertility preservation (FP). We aimed to investigate the long-term safety of FP via controlled ovarian stimulation with letrozole supplementation (COSTLES) prior to breast cancer treatment. Design, Setting, and Participants: This is a prospective, nonrandomized, controlled study conducted between the years 2002 and 2014. A total of 337 women diagnosed with stage 3 or less invasive breast cancer were enrolled during a FP consultation before chemotherapy. Of those, 120 elected to undergo COSTLES for FP prior to chemotherapy (FP group). The remaining 217 patients did not undergo any FP procedure and served as the controls. Main Outcome Measure: The primary end point was cancer recurrence defined as the detection of locoregional tumor (chest wall, regional nodal disease), distant metastases, or contralateral invasive breast cancer. Results: The baseline characteristics at enrollment were similar between the FP and control groups except for the less frequent lymph node involvement (P = .02) in the former. The mean follow-up after diagnosis was 5.0 years in the FP group and 6.9 years in the control group. In the FP group, the hazard ratio for recurrence after ovarian stimulation was 0.77 (95% confidence interval 0.28–2.13), and the survival was not compromised compared with controls (P = .61). Neither BRCA gene mutation status (P = .57) nor undergoing FP before or after breast surgery (P = .44) affected survival outcomes in the FP group. Likewise, none of the tumor characteristics including the estrogen receptor status affected the survival rates after the COSTLES. Conclusion: COSTLES is unlikely to cause a substantially increased recurrence risk in breast cancer during the 5 years after diagnosis. PMID:26751194

Patients with severe, symptomatic aortic stenosis, who do not undergo valve replacement surgery have a poor long-term prognosis. Limited data exist on the medical resource utilization and costs during the final stages of the disease. We used data from the 2003 Medicare 5% standard analytic files to identify patients with aortic stenosis and a recent hospitalization for heart failure, who did not undergo valve replacement surgery within the ensuing 2 calendar quarters. These patients (n=2150) were considered to have medically managed severe aortic stenosis and were tracked over 5 years to measure clinical outcomes, medical resource use, and costs (from the perspective of the Medicare Program). The mean age of the cohort was 82 years, 64% were female, and the estimated logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) (a measure of predicted mortality with cardiac surgery) was 17%. During 5 years of follow-up, overall mortality was 88.4% with a mean survival duration of 1.8 years. During this time period, patients experienced an average of 4.4 hospital admissions, 52% were admitted to skilled nursing care, and 28% were admitted to hospice care. The total 5-year costs were $63 844 per patient, whereas mean annual follow-up costs (excluding the index quarter) per year alive were $29 278. Elderly patients with severe aortic stenosis undergoing medical management have limited long-term survival and incur substantial costs to the Medicare Program. These results have important implications for policy makers interested in better understanding the cost-effectiveness of emerging treatment options such as transcatheter aortic valve replacement.

Surgeons are increasingly confronted by patients on long-term low-dose acetylsalicylic acid (ASA). However, owing to a lack of evidence-based data, a widely accepted consensus on the perioperative management of these patients in the setting of non-cardiac surgery has not yet been reached. Primary objective was to evaluate the safety of continuous versus discontinuous use of ASA in the perioperative period in elective general or abdominal surgery. Fifty-two patients undergoing elective cholecystectomy, inguinal hernia repair or colonic/colorectal surgery were recruited to this pilot study. According to cardiological evaluation, non-high-risk patients who were on long-term treatment with low-dose ASA were eligible for inclusion. Patients were allocated randomly to continuous use of ASA or discontinuation of ASA intake for 5 days before until 5 days after surgery. The primary outcome was the incidence of major haemorrhagic and thromboembolic complications within 30 days after surgery. A total of 26 patients were allocated to each study group. One patient (3.8%) in the ASA continuation group required re-operation due to post-operative haemorrhage. In neither study group, further bleeding complications occurred. No clinically apparent thromboembolic events were reported in the ASA continuation and the ASA discontinuation group. Furthermore, there were no significant differences between both study groups in the secondary endpoints. Perioperative intake of ASA does not seem to influence the incidence of severe bleeding in non-high-risk patients undergoing elective general or abdominal surgery. Further, adequately powered trials are required to confirm the findings of this study.

Nonsurgical treatments, such as sclerotherapy have been attempted for head and neck lymphagiomas. Of the available sclerosing agents, picibanil has shown satisfactory short-term treatment results in many studies, but no study has presented long-term treatment results. Accordingly, in the present study, the authors retrospectively reviewed the long-term treatment results of picibanil sclerotherapy. Fifty-five lymphangioma patients who underwent picibanil sclerotherapy were enrolled. Data about initial and long-term response, recurrence, and excision rate were collected. Initial response rates were 83.5 percent and long-term response rates were 76.3 percent. Initial and the long-term response rate were equally good for lymphangioma.

Although aortic valve-sparing (AVS) operations are established alternatives to composite valve graft (CVG) procedures for patients with aortic root aneurysms, comparative long-term outcomes are lacking. This study sought to compare the results of patients undergoing AVS procedures with those undergoing CVG operations. From 1990 to 2010, a total of 616 patients age <70 years and without aortic stenosis underwent elective aortic root surgery (AVS, n = 253; CVG with a bioprosthesis [bio-CVG], n = 180; CVG with a mechanical prosthesis [m-CVG], n = 183). A propensity score was used as a covariate to adjust for unbalanced variables in group comparisons. Mean age was 46 ± 14 years, 83.3% were male, and mean follow-up was 9.8 ± 5.3 years. Patients undergoing AVS had higher rates of Marfan syndrome and lower rates of bicuspid aortic valve than those undergoing bio-CVG or m-CVG procedures. In-hospital mortality (0.3%) and stroke rate (1.3%) were similar among groups. After adjusting for clinical covariates, both bio-CVG and m-CVG procedures were associated with increased long-term major adverse valve-related events compared with patients undergoing AVS (hazard ratio [HR]: 3.4, p = 0.005; and HR: 5.2, p < 0.001, respectively). They were also associated with increased cardiac mortality (HR: 7.0, p = 0.001; and HR: 6.4, p = 0.003). Furthermore, bio-CVG procedures were associated with increased risk of reoperations (HR: 6.9; p = 0.003), and m-CVG procedures were associated with increased risk of anticoagulant-related hemorrhage (HR: 5.6; p = 0.008) compared with AVS procedures. This comparative study showed that AVS procedures were associated with reduced cardiac mortality and valve-related complications when compared with bio-CVG and m-CVG. AVS is the treatment of choice for young patients with aortic root aneurysm and normal or near-normal aortic cusps. Copyright © 2016 American College of Cardiology Foundation.

While antidepressant medications are currently used during conception, gestation and post-partum, considerable uncertainty exists regarding the benefits and harms conferred to mothers and their offspring. A significant body of evidence has focused on antidepressant use during pregnancy and post-partum. However, it is difficult to know if this translates to specific populations. Women receiving treatment for infertility are especially vulnerable to symptoms of depression and adverse perinatal outcomes. This systematic review aimed to determine the effects of antidepressants taken during the perinatal period by women receiving fertility treatment on conception, birth, and long-term maternal and child health outcomes. We searched MEDLINE, EMBASE, CINAHL, the Cochrane Library, PsycINFO, ProQuest Dissertation & Theses, and Pubmed databases from January 1950 to November 2015. Articles were screened for inclusion independently by two reviewers. Studies were included if they enrolled women of reproductive age exposed to pharmacotherapy for depression and infertility at any point during the perinatal period. A total of 8587 unique citations, and 83 full-text articles were reviewed. Of these, two randomized controlled trials and two retrospective chart reviews were included in the narrative synthesis. While most studies reported on assisted reproduction processes and birth outcomes, none examined long-term impacts on maternal-child health. The few included studies did not find that antidepressant use by women receiving fertility therapy impacted gamete quality or pregnancy success. Currently, no studies address whether pharmacotherapy for the treatment of depression in women undergoing assisted reproduction affects their health or that of their offspring long-term. It appears that much like antidepressant use in fertile women, there are risks associated with both antidepressant use and untreated depression. Decisions regarding the treatment of depression should be made taking into account clinical presentation and illness severity. Given the complexities of conducting research in this population, future research should attempt to leverage health registry data, to increase sample sizes and follow mothers and children longitudinally.

2008-10-01

Long lines can be inserted centrally or peripherally through patent veins into the central venous system down to the atrial caval junction. Traditionally surgeons, anesthetists, cardiologists and more recently interventional radiologists have been placing them using vein cutdown or percutaneous needle puncture techniques. Typical candidates for implanted venous catheters are cancer patients undergoing long-term chemotherapy. The most important issues, in addition to the patency of central veins and the history of previous indwelling catheters, pacewires or venous thrombosis, are the patient's performance status, body mass index, medical history and respiratory status, and the relevant technique. The present article will give an overview of the radiological and surgical implantation techniques and will highlight the impact of imaging means on the technical feasibility, assessment and treatment of device-related complications.

Endoscopic Therapy for Achalasia Before Heller Myotomy Results in Worse Outcomes Than Heller Myotomy Alone

2006-01-01

Objective: Heller myotomy has been shown to be an effective primary treatment of achalasia. However, many physicians treating patients with achalasia continue to offer endoscopic therapies before recommending operative myotomy. Herein we report outcomes in 209 patients undergoing Heller myotomy with the majority (74%) undergoing myotomy as secondary treatment of achalasia. Methods: Data on all patients undergoing operative management of achalasia are collected prospectively. Over a 9-year period (1994–2003), 209 patients underwent Heller myotomy for achalasia. Of these, 154 had undergone either Botox injection and/or pneumatic dilation preoperatively. Preoperative, operative, and long-term outcome data were analyzed. Statistical analysis was performed with multiple χ2 and Mann-Whitney U analyses, as well as ANOVA. Results: Among the 209 patients undergoing Heller myotomy for achalasia, 154 received endoscopic therapy before being referred for surgery (100 dilation only, 33 Botox only, 21 both). The groups were matched for preoperative demographics and symptom scores for dysphagia, regurgitation, and chest pain. Intraoperative complications were more common in the endoscopically treated group with GI perforations being the most common complication (9.7% versus 3.6%). Postoperative complications, primarily severe dysphagia, and pulmonary complications were more common after endoscopic treatment (10.4% versus 5.4%). Failure of myotomy as defined by persistent or recurrent severe symptoms, or need for additionally therapy including redo myotomy or esophagectomy was higher in the endoscopically treated group (19.5% versus 10.1%). Conclusion: Use of preoperative endoscopic therapy remains common and has resulted in more intraoperative complications, primarily perforation, more postoperative complications, and a higher rate of failure than when no preoperative therapy was used. Endoscopic therapy for achalasia should not be used unless patients are not candidates for surgery. PMID:16632991

Long-term outcomes and management of the heart transplant recipient.

Cardiac transplantation remains the gold standard in the treatment of advanced heart failure. With advances in immunosuppression, long-term outcomes continue to improve despite older and higher risk recipients. The median survival of the adult after heart transplantation is currently 10.7 years. While early graft failure and multiorgan system dysfunction are the most important causes of early mortality, malignancy, rejection, infection, and cardiac allograft vasculopathy contribute to late mortality. Chronic renal dysfunction is common after heart transplantation and occurs in up to 68% of patients by year 10, with 6.2% of patients requiring dialysis and 3.7% undergoing renal transplant. Functional outcomes after heart transplantation remain an area for improvement, with only 26% of patients working at 1-year post-transplantation, and are likely related to the high incidence of depression after cardiac transplantation. Areas of future research include understanding and managing primary graft dysfunction and reducing immunosuppression-related complications. Copyright © 2017 Elsevier Ltd. All rights reserved.

The growing number of long-term cancer survivors poses a new challenge to health care systems. In Spain, follow-up is usually carried out in oncology services, but knowledge of cancer survivors' health care needs in this context is limited. The purpose of this study was to ascertain the health status of long-term survivors of breast, prostate, and colorectal cancer and to characterize their use of health care services. Retrospective multicenter cohort study. We collected data from patients' clinical histories and through telephone interviews, using a specially designed questionnaire that included the SF-36v2 Quality of Life and Nottingham Health Profile scales. The questionnaire was completed by 51.2% (n= 583) of the potential sample. No significant differences were observed between 5-year and 10-year survivors. Overall, more than 80% of respondents were undergoing drug treatment for morbidity related to advanced age. Quality of life was good in most patients, and cancer-related morbidity was low and of little complexity. For the most part, participants reported using primary care services for care of chronic diseases and opportunistic treatment of sequelae related to the cancer treatment. Oncological follow-up was centralized at the hospital. Survivors of breast, prostate and colorectal cancer with tumoral detection at an early stage and without recurrences or second neoplasms experienced little morbidity and enjoyed good quality of life. This study proposes exploration of a follow-up model in the Spanish health system in which primary care plays a more important role than is customary in cancer survivors in Spain.

Contemporary Reflections on the Safety of Long-Term Aspirin Treatment for the Secondary Prevention of Cardiovascular Disease

PubMed Central

Fanaroff, Alexander C.; Roe, Matthew T.

2018-01-01

Aspirin has been the cornerstone of therapy for the secondary prevention treatment of patients with cardiovascular disease since landmark trials were completed in the late 1970s and early 1980s that demonstrated the efficacy of aspirin for reducing the risk of ischemic events. Notwithstanding the consistent benefits demonstrated with apirin for both acute and chronic cardiovascular disease, there are a number of toxicities associated with aspirin that have been showcased by recent long-term clinical trials that have included an aspirin monotherapy arm. As an inhibitor of cyclooxygenase, aspirin impairs gastric mucosal protective mechanisms. Prior trials have shown that up to 15–20% of patients developed gastrointestinal symptoms with aspirin monotherapy and roughly 1% of patients per year had a clinically significant bleeding event, including 1 in 1000 patients who suffered an intracranial or fatal bleed. These risks have been shown to be compounded for patients with acute coronary syndromes (ACS) and those undergoing percutaneous coronary intervention (PCI), who are also treated with other anti-thrombotic agents during the acute care/procedural period, as well as for an extended time period afterwards. Given observations of substantial increases in bleeding rates from many prior long-term clinical trials that have evaluated aspirin together with other oral platelet inhibitors or oral anti-coagulants, the focus of contemporary research has pivoted towards tailored anti-thrombotic regimens that attempt to either shorten the duration of exposure to aspirin or replace aspirin with an alternative anti-thrombotic agent. While these shifts are occurring, the safety profile of aspirin when used for the secondary prevention treatment of patients with established cardiovascular disease deserves further consideration.

New highly efficacious direct-acting antiviral (DAA) therapies are available to treat chronic hepatitis C viral (HCV) infection. Real-world, patient-centered data on harms and benefits associated with these therapies are needed. PROP UP is a multi-center prospective observational study that plans to enroll 1600 patients starting treatment with recently-approved DAA regimens. Informed by extensive input from a HCV patient engagement group who prioritized outcomes most important to them, patient-reported outcomes will be characterized using surveys at five time points: Baseline (T1), treatment week 4 (T2), end of treatment (T3), 12weeks post-treatment (T4), 12months post-treatment (T5). (1) Changes in side effects, functioning, pre-existing conditions, and out-of-pocket costs during therapy (T1 vs T2/T3); (2) Medication adherence in relation to a history of mental health/substance abuse, treatment regimens, pill burden, reasons for missed doses, and cure rates; (3) Short term impact of cure on functioning and amelioration of symptoms (T1 vs T4); (4) Long-term treatment harms or benefits of cure on symptoms, side effects, pre-existing conditions, and functioning (T1 vs T5). Similarities between regimens will be examined where comparisons are appropriate and meaningful. PROP UP complements previous clinical trials by focusing on patient-reported outcomes in a representative sample of patients treated in clinical practice, by collaborating with a patient engagement group, by characterizing the experiences of vulnerable subgroups, and by investigating long-term harms and benefits of treatments. PROP UP is designed to provide novel and detailed information to support informed decision-making for patients and providers contemplating HCV treatment (PCORI CER-1408-20,660; NCT02601820).

Acute lower limb ischaemia (ALI) is the sudden onset of decreased arterial perfusion with imminent threat to limb viability. Contrast induced acute kidney injury (CI-AKI) is one of the complications that increases mortality in patients who undergo contrast imaging in coronary procedures. The goal of this study is to evaluate the impact of chronic kidney disease (CKD) and CI-AKI on long-term clinical outcomes in patients with ALI undergoing lower limb revascularisation. A total 1017 consecutive patients with acute lower limb ischaemia who were admitted between July 1, 2006, and January 1, 2017, were retrospectively reviewed. Patients who had end stage renal disease, those who had end stage heart and malignant disease and died within 7 days of limb revascularisation, and those who did not undergo angiography were excluded. Thus 546 patients were included in the final analysis. Patients were classified as with or without CKD and were then subdivided according to the presence or absence of the development of CI-AKI, defined as an increase in serum creatinine of ≥0.5 mg/dL or by ≥25% from the baseline value within the first 72 h after contrast exposure. The primary end point was all cause mortality and secondary major adverse limb event (MALE). Both CKD and CI-AKI were associated with the highest rate of all cause mortality (chi square = 55.77, d.f. = 1, p < .01, log rank test) and MALE (chi square = 79.07, d.f. = 1, p < .01, log rank test). The presence of CKD and CI-AKI were significant risk factors associated with long-term all cause mortality (HR = 2.61, p < .01) and MALE (HR = 2.87, p < .01). In patients with ALI undergoing lower limb revascularisation, both CKD and CI-AKI were significantly associated with poor long-term outcomes compared with either CKD or CI-AKI alone. Further studies are required to assess this association and to confirm the combined effect of CKD and CI-AKI on long-term clinical outcomes. Copyright © 2018 European Society for Vascular Surgery.

Comparison of cemented and uncemented fixation in total knee arthroplasty.

As a result of reading this article, physicians should be able to :1. Understand the rationale behind using uncemented fixation in total knee arthroplasty.2.Discuss the current literature comparing cemented and uncemented total knee arthroplasty3. Describe the value of radiostereographic analysis in assessing implant stability.4. Appreciate the limitations in the available literature advocating 1 mode of fixation in total knee arthroplasty. Total knee arthroplasty performed worldwide uses either cemented, cementless, or hybrid (cementless femur with a cemented tibia) fixation of the components. No recent literature review concerning the outcomes of cemented vs noncemented components has been performed. Noncemented components offer the potential advantage of a biologic interface between the bone and implants, which could demonstrate the greatest advantage in long-term durable fixation in the follow-up of young patients undergoing arthroplasty. Several advances have been made in the backing of the tibial components that have not been available long enough to yield long-term comparative follow-up studies. Short-term radiostereographic analysis studies have yielded differing results. Although long-term, high-quality studies are still needed, material advances in biologic fixation surfaces, such as trabecular metal and hydroxyapatite, may offer promising results for young and active patients undergoing total knee arthroplasty when compared with traditional cemented options.

This study aims to compare mid-long-term clinical outcomes between patients younger than 60 years of age undergoing bioprosthetic and mechanical aortic valve replacement. From January 2002 to December 2009, patients younger than 60 years of age who received Medtronic Hancock II porcine bioprostheses were selected and compared with those who received mechanical bi-leaflet valves in the aortic position. A stepwise logistic regression propensity score identified a subset of 112 evenly matched patient-pairs. Mid-long-term outcomes of survival, valve-related reoperations, thromboembolic events and bleeding events were assessed. The follow-up was only 95.1% complete. Fourteen measurable variables were statistically similar for the matched cohort. Postoperative in-hospital mortality was 3.6% (bioprosthetic valves) and 2.7% (mechanical valves) (P = 0.700). Survival at 5 and 10 years was 96.3 and 88.7% for patients receiving bioprosthetic valve replacement versus 96.3 and 87.9% for patients receiving mechanical valve replacement (P = 0.860), respectively. At 5 and 10 years after operations, freedom from valve-related reoperation was 97.2 and 94.8% for patients receiving mechanical valve replacement, and 96.3 and 90.2% for patients receiving bioprosthetic valve replacement (P = 0.296), respectively. There was no difference between freedom from thromboembolic events (P = 0.528) and bleeding events (P = 0.128) between the matched groups during the postoperative 10 years. In patients younger than 60 years of age undergoing aortic valve replacement, mid-long-term survival rate was similar for patients receiving bioprosthetic versus mechanical valve replacement. Bioprosthetic valves were associated with a trend for a lower risk of anticoagulation treatment and did not have significantly greater likelihood of a reoperation. These findings suggest that a bioprosthetic valve may be a reasonable choice for AVR in patients younger than 60 years of age. © The Author 2015.

Gordon, Pedro Caldana; Sallet, José Afonso; Sallet, Paulo Clemente

2014-10-01

A significant proportion of patients who undergo bariatric surgery fail to achieve enduring weight loss. Previous studies suggest that psychosocial variables affect postoperative outcome, although this subject is still considered unclear. The purpose of this study is to further investigate the impact of psychosocial variables on Roux-en-Y gastric bypass (RYGB) outcomes over long-term follow-up. Individuals eligible for bariatric surgery were evaluated using validated psychopathological scales and the Temperament and Character Inventory in a specialized clinic for bariatric treatment. Adult patients who had RYGB were selected for the study. Percent of excess weight loss (%EWL) was measured after surgery at 6 months, 1 year, 2 years, and on the last clinical observation. This study included 333 subjects who had RYGB. Before surgery, mean age was 35.4 years (±9.5) and mean BMI was 43.3 kg/m(2) (±4.8). Higher baseline age and BMI were associated with lower %EWL across endpoints, although this association diminished over time. Follow up at 2 years and on the last clinical observation demonstrated that lower scores on the persistence personality variable and lower body dissatisfaction before surgery predicted lower %EWL. Psychosocial variables and personality traits assessed during preoperative evaluation significantly predicted weight loss after bariatric surgery. Greater impact was observed in long-term follow-up at 2 years. These findings provide guidance in identifying patients at risk for worse outcomes and designing interventions to improve long-term weight loss.

Abstract Anastomotic leakage (AL) is one of the most serious complications of colorectal surgery. It can affect long-term oncologic outcomes, but the impact on long-term survival remains uncertain. The aim of this study is to evaluate the operative characteristics of leakage and no leakage groups and to analyze long-term oncologic outcomes. We prospectively enrolled 10,477 patients from 2000 to 2011 and retrospectively reviewed the data. Male sex (odds ratio [OR], 3.90; P < 0.001), intraoperative transfusion (OR, 2.31; P = 0.042), and operative time (OR, 1.73; P = 0.032) were independent risk factors of AL in the colon. In the rectum, male sex (OR, 2.37; P < 0.001), neoadjuvant chemoradiotherapy (OR, 2.26; P < 0.001), and regional lymph node metastasis (OR, 1.43; P = 0.012) were independent risk factors of AL, and diverting stoma (OR, 0.24; P < 0.001) was associated with a deceased risk of AL. AL in the rectum without a diverting stoma was associated with disease-free survival (DFS, OR, 1.47; P = 0.037). Colonic leakage was not associated with 5-year DFS (leakage group vs nonleakage group, 72.4% vs 80.9%, P = 0.084); however, in patients undergoing rectal resection, there was a significant difference in 5-year DFS (67.0% vs 76.6%, P = 0.005, respectively). AL in the rectum is associated with worse long-term DFS and overall survival. A diverting stoma was shown to protect against this effect and was associated with long-term survival in rectal surgery. Therefore, creating a diverting stoma should be considered in high-risk patients undergoing rectal surgery. PMID:26937928

The effect of light exposure on insomnia and nocturnal movement in Parkinson's disease: an open label, retrospective, longitudinal study.

PubMed

Martino, Jessica K; Freelance, Christopher B; Willis, Gregory L

2018-04-01

Insomnia, hypersomnia and REM Sleep Behavior Disorder (RSBD) during sleep are major problems for patients suffering from Parkinson's disease (PD) but they are also used to predict its onset. While these secondary symptoms detract from the quality of life in PD patients, few treatment options are available due to limited efficacy or risk of complicating the treatment regimen. Light therapy (LT) has been suggested as a strategy for sleep disorders but it has only been implemented recently for use in PD. An open label, retrospective study was undertaken where PD patients had been undergoing LT, using polychromatic light, for four months to 15 years prior. It was found that 1 h exposure to light, just prior to retiring, significantly improved insomnia and reduced RSBD in as little as one month after commencing LT. In addition, the improvement was maintained as long as LT was continued over a four to six year period. The efficacy of LT in alleviating these sleep related conditions was not compromised by time since diagnosis or age of the patient. These results intimate the value of long term application of non-invasive techniques such as LT for treating sleep disorders in PD and justify further controlled trials on the long term efficacy of LT.

Tinzaparin sodium: a review of its pharmacology and clinical use in the prophylaxis and treatment of thromboembolic disease.

PubMed

Cheer, Susan M; Dunn, Christopher J; Foster, Rachel

2004-01-01

Tinzaparin sodium (tinzaparin; innohep) is a low molecular weight heparin (LMWH) formed by the enzymatic degradation of porcine unfractionated heparin (UFH). In clinical trials, once-daily subcutaneous (SC) tinzaparin was effective and generally well tolerated in the prophylaxis and treatment of thromboembolic disease. SC tinzaparin 75 anti-Xa IU/kg/day showed similar thromboprophylactic efficacy to adjusted-dosage oral warfarin in patients undergoing total hip arthroplasty; in patients undergoing knee replacement, the incidence of deep vein thrombosis (DVT) was significantly lower with tinzaparin. The drug had similar efficacy to equivalent-dosage SC enoxaparin sodium in orthopaedic surgery. In patients undergoing general surgery, SC tinzaparin 3500 anti-Xa IU/day was of equivalent thromboprophylactic efficacy to SC UFH 5000IU twice daily. Encouraging preliminary results have been obtained with tinzaparin in the prevention of DVT in patients with complete motor paralysis. In the initial treatment of acute proximal DVT and pulmonary embolism, SC tinzaparin 175 anti-Xa IU/kg/day was at least as effective as adjusted-dosage intravenous (IV) UFH. In the outpatient treatment of venous thromboembolism, tinzaparin has demonstrated similar efficacy to dalteparin sodium (dalteparin) and warfarin. Tinzaparin was effective in preventing clotting in haemodialysis circuits; the anticoagulant efficacy of tinzaparin in patients undergoing haemodialysis was similar to that of SC dalteparin and similar to or less than (although in this case the tinzaparin dose was too low for sufficient anticoagulant efficacy) that of IV UFH. Advantages of tinzaparin over UFH and warfarin include ease of administration and lack of need for laboratory monitoring. Tinzaparin is more cost effective than UFH in the treatment of established thromboembolic disease, and home-based treatment with tinzaparin may offer greater cost benefits than hospital-based therapy. Tinzaparin is well tolerated, including in elderly patients and those with renal impairment receiving long-term treatment. Incidences of major bleeding complications were low and reports of heparin-induced thrombocytopenia were infrequent in clinical studies. In conclusion, tinzaparin is a valuable LMWH in the prophylaxis and management of thromboembolic disease.

Cervical cancer survivorship: Long-term quality of life and social support

Pfaendler, Krista S.; Wenzel, Lari; Mechanic, Mindy B.; Penner, Kristine R.

2015-01-01

Purpose Surgery, radiotherapy and chemotherapy are the mainstays of cervical cancer treatment. Many patients receive multiple treatment modalities, each with its own long-term effects. Given the high 5 year survival rate for cervical cancer patients, evaluation and improvement of long-term quality of life are essential. Methods Pertinent articles were identified through searches of PubMed for literature published from 1993-2014. We summarize quality of life data from long-term follow up studies of cervical cancer patients. We additionally summarize small group interviews of Hispanic and non-Hispanic cervical cancer survivors regarding social support and coping. Findings Data is varied in terms of the long term impact of treatment on quality of life but consistent in suggesting that patients who receive radiotherapy as part of their treatment have the highest risk of increased long term dysfunction of bladder and bowel, as well as sexual dysfunction and psychosocial consequences. Rigorous investigations regarding long-term consequences of treatment modalities are lacking. Implications Continued work to improve treatment outcomes and survival should also include a focus on reducing adverse long-term side effects. Providing supportive care during treatment, and evaluating the effects of supportive care, may reduce the prevalence and magnitude of long-term sequelae of cervical cancer, which will in turn improve quality of life and quality of care.

We investigate the efficiency of endoscopic mucosal resection (EMR) of non-ampullary sporadic duodenal adenomas (NASDA) in a retrospective analysis with long-term follow-up. Consecutive patients undergoing EMR of NASDA between May 2002 and December 2016 were retrospectively identified from an electronic database. Endoscopic follow-up was scheduled after 3, 6 and 12 months for the first year, then yearly for up to five years. EMR of 75 NASDA was performed in 68 patients (56% en-bloc, 44% piecemeal). Retroperitoneal perforations occurred in 3/68 (4.4%) patients, were treated by surgical (n = 2) or percutaneous (n = 1) drainage; delayed bleeding was reported in 13/75 (17.3%) resections and was successfully managed by endoscopy (n = 12) or radiologic embolization (n = 1). There was no procedure-related mortality. Follow-up was available in 61/68 patients (89.7%) after a median time of 59 months from resection. Residual and recurrent adenoma were diagnosed in 9 (14.5%) and 6 (10.9%) cases, respectively; all but one were successfully retreated endoscopically. EMR for NASDA is effective with a favorable long-term outcome. Local recurrences can be retreated endoscopically. A recall system, patient's compliance to endoscopic follow-up are mandatory to detect recurrences and their prompt treatment.

Our objective was to compare survival and complication rates of horses undergoing pelvic flexure enterotomy closure with a TA-90 stapler to those with hand-sewn closure. Medical records of horses undergoing pelvic flexure enterotomy between 2001 and 2008 were reviewed. History, clinical signs, surgical findings, surgical techniques, and post-operative complications were recorded. Long-term outcome was established by telephone questionnaire. Of 84 pelvic flexure enterotomies performed, 70 were stapled and 14 were hand-sewn. Seventy-seven horses survived to discharge (91.7%). There were no significant associations between survival and closure technique (P = 0.69). Follow-up was available for 54 horses; 50 survived long-term (93.0%). No statistical significance was identified between long-term survival and closure method (P = 0.39). Forty horses went on to athletic performance (80.0%). TA-90 stapled closure of pelvic flexure enterotomies is a safe technique resulting in survival and complication rates equivalent to those of hand-sewn closure. PMID:23204584

The risk of bronchospasm in asthmatics undergoing general anaesthesia and/or intravascular administration of radiographic contrast media. physiopatology and clinical/functional evaluation.

It is well known that patients suffering from bronchial asthma undergoing to surgical procedures requiring general anaesthesia (GA) or the administration of water soluble radiographic contrast media (RCM) experience a risk of potentially severe bronchospasm. Nevertheless, little attention has been devoted on the possible preventive measures to reduce the occurrence of this potentially life-threatening event. It has been shown that the most important risk factor for bronchospasm during GA induction and/or the use of RCM is represented by a high degree of bronchial hyperreactivity with airway instability not adequately controlled by long-term anti-inflammatory treatment. The aim of this review is to underline the need for an accurate clinical and functional evaluation of asthmatics (especially those with a relevant degree of asthma severity) undergoing GA or administration of RCM. Guidelines shared by pulmonologists, allergologists, anesthesiologists and radiologists should be produced in the future for a better evaluation and management of these patients. General practitioner plays an important role in managing asthmatic patients in "Real Life". It is likely that "Real Life"--optimally controlled asthmatics could undergo GA/RCM with lower risks especially in emergency conditions when it is not possible to perform any preoperative evaluation.

Resection of the involved mesenteric-portal vein (MPV) is increasingly performed in pancreatoduodenectomy. The primary aim of this study is to assess the rate of R0 resection in transverse closure (TC) versus segmental resection with end-to-end (EE) closure and the secondary aims are to assess the short-term morbidity and long-term survival of TC versus EE. Patients undergoing pancreatoduodenectomy with MPV resection were identified from a prospectively database. The reconstruction technique were examined and categorized. Clinical, pathological, short-term and long-term survival outcomes were compared between groups. 110 patients underwent PD with MPV resection of which reconstruction was performed with an end-to-end technique in 92 patients (84%) and transverse closure technique in 18 patients (16%). Patients undergoing transverse closure tended to have had a shorter segment of vein resected (≤2 cm) compared to the end-to-end (83% vs. 43%; P = 0.004) with no difference in R0 rate. Short-term morbidity was similar. The median and 5-year survival was 30.0 months and 18% respectively for patients undergoing transverse closure and 28.6 months and 7% respectively for patients undergoing end-to-end reconstruction (P = 0.766). Without compromising the R0 rate, transverse closure to reconstruct the mesenteric-portal vein is shown to be feasible and safe in the setting when a short segment of vein resection is required during pancreatoduodenectomy. Synopsis - We describe a vein closure technique, transverse closure, which avoids the need for a graft, or re-implantation of the splenic vein when resection of the mesenteric-portal vein confluence is required during pancreatoduodenectomy.

2007-01-01

Long-term total parenteral nutrition (TPN) is a procedure commonly applied to patients with advanced forms of intestinal malabsorption. Among TPN complications, bone metabolic diseases, such as osteoporosis and osteomalacia, are a common finding. Initially considered to be a manifestation of aluminium toxicity which followed massive contamination with the element of the solutions used in TPN, metabolic osteopathy during TPN is currently considered a multiform syndrome, with a multifactorial pathogenesis, which may manifest itself with vague or clear clinical pictures. In this review, we analyse clinical, pathogenetic, and therapeutic aspects of the most common bone metabolic diseases in patients undergoing long-term TPN.

Levels of mania and cognitive performance two years after ECT in patients with bipolar I disorder - results from a follow-up study.

There is limited evidence on the long-term outcomes for patients with bipolar I disorder (BP-I-D) and treated with ECT. Therefore, we asked whether mania scores and cognitive performance at the end of ECT treatment (baseline/BL) predicted mania scores, cognitive performance, recurrence, treatment adherence, and mood (depression; hypomania) two years later (follow-up/FU). 38 patients with BP-I-D undergoing ECT at baseline were followed up two years later. A brief psychiatric and cognitive assessment (Mini Mental State Examination; short-term verbal memory test) was performed; patients completed questionnaires covering recurrence, treatment adherence, and mood (depression; hypomania). High cognitive performance at BL predicted high cognitive performance at FU; low mania scores at BL predicted low mania scores at FU. By FU, cognitive performance had increased and mania scores decreased. Mania scores and cognitive performance at BL did not predict recurrence, or adherence to medication, or mood (depression; hypomania). The pattern of results suggests that after two years of successful treatment of acute mania with ECT, cognitive impairment, measured by MMSE and a short-term verbal memory test, is not impaired and mood symptom recurrence seems to be improved. Mania scores and cognitive performance at the end of ECT treatment predicted neither mood (depression; hypomania), nor recurrence, or adherence to medication two years later.

To ascertain primary motivation and long-term satisfaction with treatment selection in patients with vestibular schwannoma. A multicenter, cross-sectional survey was performed. Patients with small- to medium-sized sporadic vestibular schwannoma who underwent stereotactic radiosurgery (SRS; n = 247), microsurgery (n = 144), or observation (n = 148) between 1998 and 2008 were surveyed regarding their motivation behind treatment selection and hindsight satisfaction with their choice of management. "Physician recommendation" was the most commonly stated reason for modality selection in all 3 groups. The second and third most common reasons for selecting SRS included "less invasive option than surgery" in 80 patients (32%) and "less recovery time than surgery" in 16 patients (6%). The second and third most common reasons for selecting observation included "to avoid side-effects of treatment" in 25 patients (17%) and "symptoms not severe enough to warrant intervention" in 22 patients (15%). The second and third most common reasons for selecting microsurgery included "do not want tumor in head" in 35 patients (24%) and "most definitive treatment" in 15 patients (10%). Overall, 232 patients (96%) treated with SRS, 141 observed patients (97%), and 121 patients (85%) who underwent microsurgical treatment were satisfied with their original decision (P < 0.001). Motivation behind treatment selection varies between individuals. Those who select observation and SRS commonly reference less invasiveness and lower risk, whereas those who select microsurgery are commonly motivated by having their tumor physically removed and the more definitive nature of treatment. Posttreatment satisfaction is highest in patients who undergo SRS and observation, although all 3 groups report high levels of satisfaction. Copyright © 2018 Elsevier Inc. All rights reserved.

Cervical radiculopathy may cause symptoms and loss of function that can lead to a significant reduction in health related quality of life (HRQOL). As part of a comprehensive review of long-term outcomes, we examined HRQOL in a large cohort of patients undergoing posterior cervical foraminotomy (FOR) for radiculopathy. 338 patients who underwent FOR between 1990 and 2009 participated in a telephone interview designed to measure symptomatic and functional improvements following surgery. We also administered the EQ-5D, a standardized tool for assessing HRQOL. We analyzed this data for associations between patient and treatment characteristics, improvements in symptoms and function, and HRQOL as measured by the EQ-5D. Mean follow-up was 10.0 years. The average EQ-5D at follow-up was 0.81±0.18, and improvements in pain, weakness and function as well as ability to return to work correlated with improved EQ-5D score (p<0.0001). There was no correlation between length of follow-up and EQ-5D score (p=0.980). Additionally, there was no difference between mean EQ-5D score for soft disc versus osteophyte pathology (0.84 versus 0.81, p=0.21). These data provide evidence that FOR for cervical radiculopathy is associated with improved HRQOL at long-term follow-up. The lack of correlation between length of follow-up and HRQOL suggests that FOR is a durable treatment option. Moreover, FOR is associated with improved HRQOL whether radiculopathy is due to soft disc or osteophyte pathology. Copyright © 2016 Elsevier B.V. All rights reserved.

Longitudinal intestinal lengthening and tailoring (LILT) is a well-established surgical treatment for short bowel syndrome. It has been shown to enhance peristalsis, decrease bacterial overgrowth, and extend mucosal contact time for nutrients. We present the results of a long-term follow-up of patients who underwent LILT and define prognostic parameters for the survival of these patients. Between 1987 and 2006, 53 patients underwent LILT in our institution. The main diagnoses were gastroschisis, intestinal volvulus, intestinal atresias, and necrotizing enterocolitis. LILT was performed at a mean age of 24 months (range 4144 months). The follow-up time was 79.76 months (range 6234 months). After LILT, 41 of 53 patients survived, and 36 of 41 surviving patients were successfully weaned from parenteral nutrition (PN). In long-term follow-up 79% stayed free of PN. The overall survival rate was 77.36%. Weight gain occurred in 58% of the patients after LILT. The quality of life after LILT is on a high level, with most patients having normal physical strength and participating in normal social life and education. Prognostic factors for survival after LILT in short bowel syndrome are length of small intestine (0.06582 + 0.0131 x bowel cm), length of large bowel (P = 0.039), preoperative liver function, and successful weaning from PN within 18 months postoperatively (P = 0.0032). Patients undergoing LILT in short bowel syndrome have a high survival rate, weight gain, and a high quality of life. Autologous gastrointestinal reconstruction remains therefore the first choice in the treatment of patients with short bowel syndrome.

The undeniable advances in the field of oncology have finally led to a decrease in overall cancer-related mortality. However, this population of long-term cancer survivors is now facing a shift toward a substantial increase in cardiovascular morbidity and mortality. Because the development of overt cardiotoxicity can be associated with poor outcomes, preclinical identification of cardiac toxicity is important. This will promote early instauration of treatments to prevent overt heart dysfunction and allow oncologists to continue cancer therapy in an uninterrupted manner. Surveillance strategies for the early detection of cardiac injury include cardiac imaging and biomarkers during treatment. In this review, we outline existing cardiac imaging modalities to detect myocardial changes in patients undergoing cancer treatment and in survivors, and their strengths and limitations.

Aim: To study the effect of carbon dioxide (CO2) therapy on the nitric oxide (NO) pathway by monitoring plasma asymmetric dimethylarginine (ADMA) concentrations. Patients and Methods: Forty-seven hypertensive patients who underwent transcutaneous CO2 therapy were enrolled. Thirty healthy individuals were recruited for the control group. Blood samples were taken one hour before, as well as one hour, 24 hours and 3 weeks after the first CO2 treatment. Controls did not undergo CO2 treatment. Plasma ADMA levels were measured by ELISA. Results: ADMA levels decreased significantly one hour after the first CO2 treatment compared to the baseline concentrations (p=0.003). Significantly greater reduction was found among patients in whom angiotensin converting enzyme inhibitors (ACEIs) were administered (p=0.019). Conclusion: The short- and long-term decrease of ADMA levels suggests that CO2 is not only a vasodilator, but also has a beneficial effect on the NO pathway. ACE inhibition seems to enhance the effect of CO2 treatment. PMID:28438873

Prehypertension has been associated with adverse cerebrovascular events and brain damage. The aims of this study were to investigate ⅰ) whether short‑ and long-term treatments with losartan or amlodipine for prehypertension were able to prevent blood pressure (BP)-linked brain damage, and ⅱ) whether there is a difference in the effectiveness of treatment with losartan and amlodipine in protecting BP-linked brain damage. In the present study, prehypertensive treatment with losartan and amlodipine (6 and 16 weeks treatment with each drug) was performed on 4-week‑old stroke-prone spontaneously hypertensive rats (SHRSP). The results showed that long-term (16 weeks) treatment with losartan is the most effective in lowering systolic blood pressure in the long term (up to 40 weeks follow-up). Additionally, compared with the amlodipine treatment groups, the short‑ and long-term losartan treatments protected SHRSP from stroke and improved their brains structurally and functionally more effectively, with the long-term treatment having more benefits. Mechanistically, the short‑ and long-term treatments with losartan reduced the activity of the local renin-angiotensin-aldosterone system (RAAS) in a time-dependent manner and more effectively than their respective counterpart amlodipine treatment group mainly by decreasing AT1R levels and increasing AT2R levels in the cerebral cortex. By contrast, the amlodipine treatment groups inhibited brain cell apoptosis more effectively as compared with the losartan treatment groups mainly through the suppression of local oxidative stress. Taken together, the results suggest that long-term losartan treatment for prehypertension effectively protects SHRSP from stroke-induced brain damage, and this protection is associated with reduced local RAAS activity than with brain cell apoptosis. Thus, the AT1R receptor blocker losartan is a good candidate drug that may be used in the clinic for long-term treatment on prehypertensive populations in order to prevent BP-linked brain damage.

The human brain is capable of generating new functional neurons throughout life, a phenomenon known as adult neurogenesis. The generation of new neurons is sustained throughout adulthood due to the proliferation and differentiation of adult neural stem cells. This process in humans is uniquely located in the subgranular zone of the dentate gyrus in the hippocampus. Adult hippocampal neurogenesis (AHN) is thought to play a major role in hippocampus-dependent functions, such as spatial awareness, long-term memory, emotionality, and mood. The overall aim of current treatments for cancer (such as radiotherapy and chemotherapy) is to prevent aberrant cell division of cell populations associated with malignancy. However, the treatments in question are absolutist in nature and hence inhibit all cell division. An unintended consequence of this cessation of cell division is the impairment of adult neural stem cell proliferation and AHN. Patients undergoing treatment for cancerous malignancies often display specific forms of memory deficits, as well as depressive symptoms. This review aims to discuss the effects of cancer treatments on AHN and propose a link between the inhibition of the neurogenetic process in the hippocampus and the advent of the cognitive and mood-based deficits observed in patients and animal models undergoing cancer therapies. Possible evidence for coadjuvant interventions aiming to protect neural cells, and subsequently the mood and cognitive functions they regulate, from the ablative effects of cancer treatment are discussed as potential clinical tools to improve mental health among cancer patients.

Preoperative low skeletal muscle mass and density are associated with increased postoperative morbidity in patients undergoing curative colorectal cancer (CRC) surgery. However, the long-term effects of low skeletal muscle mass and density remain uncertain. Patients with stage I-III CRC undergoing surgery, enrolled in a prospective observational cohort study, were included. Skeletal muscle mass and density were measured on CT. Patients with high and low skeletal muscle mass and density were compared regarding postoperative complications, disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS). In total, 816 patients (53.9% males, median age 70) were included; 50.4% had low skeletal muscle mass and 64.1% low density. The severe postoperative complication rate was significantly higher in patients with low versus high skeletal muscle and density (20.9% versus 13.6%, p = 0.006; 20.0% versus 11.8%, p = 0.003). Low skeletal muscle mass (OR 1.91, p = 0.018) and density (OR 1.87, p = 0.045) were independently associated with severe postoperative complications. Ninety-day mortality was higher in patients with low skeletal muscle mass and density compared with patients with high skeletal muscle mass and density (3.6% versus 1.7%, p = 0.091; 3.4% versus 1.0%, p = 0.038). No differences in DFS were observed. After adjustment for covariates such as age and comorbidity, univariate differences in OS and CSS diminished. Low skeletal muscle mass and density are associated with short-term, but not long-term, outcome in patients undergoing CRC surgery. These findings recommend putting more emphasis on preoperative management of patients at risk for surgical complications, but do not support benefit for long-term outcome.

Under the Freedom of Information Act, we obtained the follow-up data of the National Emphysema Treatment Trial (NETT) to determine the long-term outcome for "a heterogeneous distribution of emphysema with upper lobe predominance," postulated by the NETT hypothesis to be optimal candidates for lung volume reduction surgery. Using the NETT database, we identified patients with heterogeneous distribution of emphysema with upper lobe predominance and analyzed for the first time follow-up data for those receiving lung volume reduction surgery and those receiving medical management. Furthermore, we compared the results of the NETT reduction surgery group with a previously reported consecutive case series of 250 patients undergoing bilateral lung volume reduction surgery using similar selection criteria. Of the 1218 patients enrolled, 511 (42%) conformed to the NETT hypothesis selection criteria and received the randomly assigned surgical or medical treatment (surgical = 261; medical = 250). Lung volume reduction surgery resulted in a 5-year survival benefit (70% vs 60%; P = .02). Results at 3 years compared with baseline data favored surgical reduction in terms of residual volume reduction (25% vs 2%; P < .001), University of California San Diego dyspnea score (16 vs 0 points; P < .001), and improved St George Respiratory Questionnaire quality of life score (12 points vs 0 points; P < .001). For the 513 patients with a homogeneous pattern of emphysema randomized to surgical or medical treatment, lung volume reduction surgery produced no survival advantage and very limited functional benefit. Patients most likely to benefit from lung volume reduction surgery have heterogeneously distributed emphysema involving the upper lung zones predominantly. Such patients in the NETT trial had results nearly identical to those previously reported in a nonrandomized series of similar patients undergoing lung volume reduction surgery. 2010 The American Association for Thoracic Surgery.

In this report, we examined the antitumor activity of photodynamic therapy (PDT) in combination with 5,6-dimethylxanthenone- 4-acetic acid (DMXAA), a vascular disrupting agent currently undergoing clinical evaluation. BALB/c mice bearing subcutaneous CT-26 colon carcinomas were treated with PDT using the second-generation chlorin-based sensitizer, 2-[1-hexyloxyethyl]-2-devinyl pyropheophorbide-a (Photochlor) with or without DMXAA. Long-term (60-days) treatment outcome, induction of tumor necrosis factor-alpha (TNF-α) and interleukin- 6 (IL-6), vascular damage (microvessel density, MVD) were evaluated as endpoints. In addition, treatment selectivity was evaluated using magnetic resonance imaging (MRI) and the foot response assay. A highly synergistic interaction was observed with the combination of low-dose DMXAA and PDT (48 J cm−2 at 112 mW cm−2) resulting in ~60% long-term cures. The duration of the PDT session for this combination therapy protocol was only 7 min, while the duration of a monotherapy PDT session, selected to yield the equivalent cure rate, was 152 min. MRI showed markedly less peritumoral edema after DMXAA + short-duration PDT compared with long-duration PDT monotherapy. Similarly, DMXAA + PDT caused significantly less phototoxicity to normal mouse foot tissue than PDT alone. Increased induction of cytokines TNF-α and IL-6 (P < 0.001) was observed at 4 h followed by extensive vascular damage, demonstrated by a significant reduction in MVD at 24 h after combination treatment. In conclusion, Photochlorsensitized PDT in combination with DMXAA exhibits superior efficacy and improved selectivity with clinically feasible illumination schemes. Clinical evaluation of this novel combination strategy is currently being planned. PMID:18643909

Physiologically-relevant measurements of flow through coils and stents: towards improved modeling of endovascular treatment of intracranial aneurysms

The hemodynamic environment in cerebral aneurysms undergoing flow-diverting stent (FDS) or coil embolization treatment plays a critical role in long-term outcomes. Standard modeling approaches to endovascular coils and FDS simplify the complex geometry into a homogenous porous volume or surface through the addition of a Darcy-Brinkman pressure loss term in the momentum equation. The inertial and viscous loss coefficients are typically derived from published in vitro studies of pressure loss across FDS and coils placed in a straight tube, where the only fluid path is across the treatment - an unrealistic representation of treatment apposition in vivo. The pressure drop across FDS and coils in side branch aneurysms located on curved parent vessels is measured. Using PIV, the velocity at the aneurysm neck plane is reconstructed and used to determine loss coefficients for better models of endovascular coils or FDS that account for physiological placement and vessel curvature. These improved models are incorporated into CFD simulations and validated against in vitro model PIV velocity, as well as compared to microCT-based coil/stent-resolving CFD simulations of patient-specific treated aneurysm flow.

Bisphosphonates have been related to impaired bone remodeling. The impact of oral bisphosphonates on periradicular healing has not been studied. The purpose of this study was to evaluate the healing of periradicular lesions in patients taking oral bisphosphonates after root canal therapy. Thirty-four teeth with preoperative periradicular radiolucencies were identified in patients undergoing oral bisphosphonate therapy. These cases were examined clinically and radiographically to determine treatment outcome. Thirty-eight control teeth were selected from a pool of patients not taking bisphosphonates. Nonsurgical root canal treatment and retreatment was performed by endodontic residents and undergraduate dental students at Baylor College of Dentistry using nonstandardized protocols. In the bisphosphonate group, 73.5% of the lesions healed, whereas the control cases had a healing rate of 81.6%. There was no statistically significant difference between the groups (p > 0.05). The results of this preliminary short-term study suggest that patients taking long-term oral bisphosphonates can expect a satisfactory outcome with evidence of periradicular healing after conventional root canal treatment. Thus, root canal treatment may be considered a safe and realistic alternative to extraction in patients on bisphosphonate therapy.

The long-established notion that apoptosis would be immunologically silent, and hence it would go unnoticed by the immune system, if not tolerogenic, and hence it would actively suppress immune responses, has recently been revisited. In some instances, indeed, cancer cells undergo apoptosis while emitting a spatiotemporally-defined combination of signals that renders them capable of eliciting a long-term protective antitumor immune response. Importantly, only a few anticancer agents can stimulate such an immunogenic cell death. These include cyclophosphamide, doxorubicin and oxaliplatin, which are currently approved by FDA for the treatment of multiple hematologic and solid malignancies, as well as mitoxantrone, which is being used in cancer therapy and against multiple sclerosis. In this Trial Watch, we will review and discuss the progress of recent (initiated after January 2008) clinical trials evaluating the off-label use of cyclophosphamide, doxorubicin, oxaliplatin and mitoxantrone.

Achalasia is an oesophageal motor disorder which leads to the functional obstruction of the lower oesophageal sphincter (LES) and is currently incurable. The main objective of all existing therapies is to achieve a reduction in the obstruction of the distal oesophagus in order to improve oesophageal transit, relieve the symptomatology, and prevent long-term complications. The most common treatments used are pneumatic dilation (PD) and laparoscopic Heller myotomy, which involves partial fundoplication with comparable short-term success rates. The most economic non-surgical therapy is PD, with botulinum toxin injections reserved for patients with a higher surgical risk for whom the former treatment option is unsuitable. A new technology is peroral endoscopic myotomy, postulated as a possible non-invasive alternative to surgical myotomy. Other endoluminal treatments subject to research more recently include injecting ethanolamine into the LES and using a temporary self-expanding metallic stent. At present, there is not enough evidence permitting a routine recommendation of any of these three novel methods. Patients must undergo follow-up after treatment to guarantee that their symptoms are under control and to prevent complications. Most experts are in favour of some form of endoscopic follow-up, however no established guidelines exist in this respect. The prognosis for patients with achalasia is good, although a recurrence after treatment using any method requires new treatment. PMID:26078828

To examine the effect of subthreshold diode micropulse laser (SDM) on pattern electroretinography (PERG) and visual function in retinitis pigmentosa (RP). The records of all patients (pts) undergoing SDM in a vitreoretinal subspecialty practice were reviewed. Inclusion criteria included the presence of RP evaluated before and after SDM by PERG. As a secondary outcome measure, the results of automated omnifield resolution perimetry (ORP) were also reviewed. All eyes undergoing SDM for RP were eligible study, including 26 eyes of 15 pts; seven male and eight female, aged 16-69 (avg. 47) years. Retinal function by PERG improved by all indices, with significant improvements in the 24° field signal latency measures; the MagD(µV)/ Mag(µV) ratio (P < 0.0001) and the MagD(µV) amplitude (P = 0.0003). ORP significantly improved by all indices (p = 0.02-0.002). Average best-corrected chart visual acuities improved from 0.6 to 0.4 logMAR units (p = 0.02). There were no adverse treatment effects. SDM significantly improved chart visual acuity, mesopic logMAR visual acuity perimetry, and retinal function by PERG in RP without adverse treatment effects. Treatment responses indicate a significant capacity for rescue of dysfunctional retina. These results suggest that early and periodic treatment with SDM might slow disease progression and reduce long-term vision loss.

Ablation of Barrett's oesophagus: towards improved outcomes for oesophageal cancer?

PubMed

Mayne, George C; Bright, Tim; Hussey, Damian J; Watson, David I

2012-09-01

Barrett's oesophagus is the major risk factor for the development of oesophageal adenocarcinoma. The management of Barrett's oesophagus entails treating reflux symptoms with acid-suppressing medication or surgery (fundoplication). However, neither form of anti-reflux therapy produces predictable regression, or prevents cancer development. Patients with Barrett's oesophagus usually undergo endoscopic surveillance, which aims to identify dysplastic changes or cancer at its earliest stage, when treatment outcomes should be better. Alternative endoscopic interventions are now available and are suggested for the treatment of early cancer and prevention of progression of Barrett's oesophagus to cancer. Such treatments could minimize the risks associated with oesophagectomy. The current status of these interventions is reviewed. Various endoscopic interventions have been described, but with long-term outcomes uncertain, they remain somewhat controversial. Radiofrequency ablation of dysplastic Barrett's oesophagus might reduce the risk of cancer progression, although cancer development has been reported after this treatment. Endoscopic mucosal resection (EMR) allows a 1.5-2 cm diameter piece of oesophageal mucosa to be removed. This provides better pathology for diagnosis and staging, and if the lesion is confined to the mucosa and fully excised, EMR can be curative. The combination of EMR and radiofrequency ablation has been used for multifocal lesions, but long-term outcomes are unknown. The new endoscopic interventions for Barrett's oesophagus and early oesophageal cancer have the potential to improve clinical outcomes, although evidence that confirms superiority over oesphagectomy is limited. Longer-term outcome data and data from larger cohorts are required to confirm the appropriateness of these procedures. © 2012 The Authors.

The aim of this study was to evaluate short- and long-term outcome in patients undergoing coronary artery bypass grafting (CABG), who received an intra-aortic balloon pump (IABP) prior to surgery. Between January 1990 and June 2004, all patients (n=154) who received an IABP prior to on-pump CABG in our center were included. Patients received the IABP for vital indications (i.e. either unstable angina refractory to medical therapy or cardiogenic shock; group 1: n=99) or for prophylactic reasons (group 2: n=55). A Cox proportional hazards model was used to identify predictors of long-term all-cause mortality. Compared with the EuroSCORE predictive model, observed 30-day mortality in group 1 (15.2%) was slightly higher than predicted (10.3%). A decrease in 30-day mortality occurred in group 2 (median predicted mortality was 7.2% and observed was 0%). Cumulative 1-, 5-, and 6-year survival was 82.8+/-3.8%, 70.1+/-4.9%, and 67.3+/-5.1% for group 1 vs. 98.2+/-1.8%, 84.0+/-5.6% and 84.0+/-5.6% for group 2 (Log-rank: P=0.02). Logistic EuroSCORE (HR 1.03 [1.01-1.05], P=0.007) was an independent predictor of long-term all-cause mortality.

To assess patients' symptoms, quality of life and satisfaction with information three to four years after radical prostatectomy, radical external beam radiotherapy and postoperative radiotherapy and to analyse differences between treatment groups and the relationship between disease-specific, health-related and overall quality of life and satisfaction with information. Radical prostate cancer treatments are associated with changes in quality of life. Differences between patients undergoing different treatments in symptoms and quality of life have been reported, but there are limited long-term data comparing radical prostatectomy with radical external beam radiotherapy and postoperative radiotherapy. A cross-sectional survey design was used. The study sample included 143 men treated with radical prostatectomy and/or radical external beam radiotherapy. Quality of life was measured using the 12-item Short Form Health Survey and the 50-item Expanded Prostate Cancer Index Composite Instrument. Questions assessing overall Quality of life and satisfaction with information were included. Descriptive statistics and interference statistical methods were applied to analyse the data. Radical external beam radiotherapy was associated with less urinary incontinence and better urinary function. There were no differences between the groups for disease-specific quality of life sum scores. Sexual quality of life was reported very low in all groups. Disease-specific quality of life and health-related quality of life were associated with overall quality of life. Patients having undergone surgery were more satisfied with information, and there was a positive correlation between quality of life and patient satisfaction. Pretreatment information and patient education lead to better quality of life and satisfaction. This study indicates a need for structured, pretreatment information and follow-up for all men going through radical prostate cancer treatment. Long-term quality of life effects should be considered when planning follow-up and information for men after radical prostate cancer treatment. Structured and organised information/education may increase preparedness for symptoms and bother after the treatment, improve symptom management strategies and result in improved quality of life. © 2014 John Wiley & Sons Ltd.

High-dose (4.0 g/day) mesalazine is typically used for induction therapy, but its efficacy as maintenance therapy remains to be determined. We conducted a multicenter retrospective study to investigate the efficacy of continuous treatment with 4.0 g/day of mesalazine. Japanese ulcerative colitis (UC) patients receiving acute induction therapy with 4.0 g/day mesalazine were enrolled and followed. Those who clinically improved or who achieved clinical remission were categorized into 2 sub-groups according to the median duration of treatment with 4.0 g/day of mesalazine. The clinical relapse frequency and the time to relapse were analyzed. We enrolled 180 patients with active UC, and then 115 patients who clinically improved or who achieved clinical remission after treatment with 4.0 g/day mesalazine were categorized into 2 sub-groups according to the median of treatment duration: a short-term treatment group (≤105 days, n=58) and a long-term treatment group (>105 days, n=57). Overall, 45 (39.1%) patients relapsed: 28 (48.3%) in the short-term treatment group and 17 (29.8%) in the long-term treatment group. This difference was statistically significant (p<0.05). The relapse-free rate in the long-term treatment group was significantly higher than that in the short-term treatment group (p<0.05). The mean time to relapse in the long-term treatment group was significantly longer than that in the short-term treatment group (425.6±243.8 days vs. 277.4±224.5 days; p<0.05). Long-term continuous treatment with high-dose mesalazine (4.0 g/day) may be more effective than short-term treatment for maintenance of remission in UC patients.

Recent studies show that proinflammatory cytokines might be related to the development of opioid dependence (physiological, psychological, or both). In a double-blind, randomly stratified clinical trial investigating whether add-on dextromethorphan (60-120 mg/day) attenuated inflammation and the combined use of opioids in heroin-dependent patients undergoing methadone maintenance treatment, we evaluated whether inflammation is related to the progression of opioid dependence. All participants (107 heroin-dependent patients and 84 nondependent healthy controls) were recruited from National Cheng Kung University Hospital. Their plasma cytokine levels were measured to evaluate the effect of add-on dextromethorphan. Plasma TNF-α and IL-8 levels were significantly higher in long-term heroin-dependent patients than in healthy controls (p < 0.001). Chronic heroin-use-induced TNF-α and IL-8 levels were significantly (p < 0.05) attenuated in patients treated for 12 weeks with add-on dextromethorphan. Moreover, both tolerance to methadone and the combined use of opioids were significantly (p < 0.05) attenuated in patients taking dextromethorphan. We conclude that dextromethorphan might be a feasible adjuvant therapeutic for attenuating inflammation and inhibiting methadone tolerance and combined opioid use in heroin-dependent patients.

Platelet inhibition has been considered an effective strategy for combating cancer metastasis and compromising disease malignancy although recent clinical data provided evidence that long-term platelet inhibition might increase incidence of cancer deaths in initially cancer-free patients. In the present study we demonstrated that dual anti-platelet therapy based on aspirin and clopidogrel (ASA+Cl), a routine regiment in cardiovascular patients, when given to cancer-bearing mice injected orthotopically with 4T1 breast cancer cells, promoted progression of the disease and reduced mice survival in association with induction of vascular mimicry (VM) in primary tumour. In contrast, treatment with ASA+Cl or platelet depletion did reduce pulmonary metastasis in mice, if 4T1 cells were injected intravenously. In conclusion, distinct platelet-dependent mechanisms inhibited by ASA+Cl treatment promoted cancer malignancy and VM in the presence of primary tumour and afforded protection against pulmonary metastasis in the absence of primary tumour. In view of our data, long-term inhibition of platelet function by dual anti-platelet therapy (ASA+Cl) might pose a hazard when applied to a patient with undiagnosed and untreated malignant cancer prone to undergo VM.

Background: A case is discussed in which a young girl was born with symbrachydactyly of multiple digits in whom nonvascularized proximal toe phalanges were transferred to the aphalangic digits at the age of four. At 39 years of age, she presented incidentally to our clinic and was observed to have a very functional hand with mobile metacarpophalangeal joints in all reconstructed digits. Methods: We present a case report which is discussed in the context of long-term follow-up, and phalangeal growth in the absence of distraction, and a review of the current literature in regards to outcomes for this modality of treatment. Results: We document growth of the transplanted phalanges, despite surgery occurring after the reported optimum age of before 18 months, and the patient not undergoing distraction. The patient reported no donor site morbidity in regards to function or psychosocial impact. Furthermore, we observed active function at the metacarpophalangeal joints of all operated digits. Conclusions: We report the longest follow-up (35 years) following nonvascularized proximal toe phalangeal transfer for short finger type symbrachydactyly. We highlight the long-term functional outcome of nonvascularized toe phalangeal transfers, and present an overview of the current outcome literature for this type of procedure, advocating that nonvascularized toe phalangeal transfers remain a viable treatment option for select cases of symbrachydactyly.

To identify the main issues of importance when living with long-term conditions to refine a conceptual framework for informing the item development of a patient-reported outcome measure for long-term conditions. Semi-structured qualitative interviews (n=48) were conducted with people living with at least one long-term condition. Participants were recruited through primary care. The interviews were transcribed verbatim and analyzed by thematic analysis. The analysis served to refine the conceptual framework, based on reviews of the literature and stakeholder consultations, for developing candidate items for a new measure for long-term conditions. Three main organizing concepts were identified: impact of long-term conditions, experience of services and support, and self-care. The findings helped to refine a conceptual framework, leading to the development of 23 items that represent issues of importance in long-term conditions. The 23 candidate items formed the first draft of the measure, currently named the Long-Term Conditions Questionnaire. The aim of this study was to refine the conceptual framework and develop items for a patient-reported outcome measure for long-term conditions, including single and multiple morbidities and physical and mental health conditions. Qualitative interviews identified the key themes for assessing outcomes in long-term conditions, and these underpinned the development of the initial draft of the measure. These initial items will undergo cognitive testing to refine the items prior to further validation in a survey.

Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty. Although research suggests that Continuous Passive Motion (CPM) should be implemented in the first rehabilitation phase after surgery, there is substantial debate about the duration of each session and the total period of CPM application. A Cochrane review on this topic concluded that short-term use of CPM leads to greater short-term range of motion. It also suggested, however, that future research should concentrate on the treatment period during which CPM should be administered. In a randomised controlled trial we investigated the effectiveness of prolonged CPM use in the home situation as an adjunct to standardised PT. Efficacy was assessed in terms of faster improvements in range of motion (RoM) and functional recovery, measured at the end of the active treatment period, 17 days after surgery. Sixty patients with knee osteoarthritis undergoing TKA and experiencing early postoperative flexion impairment were randomised over two treatment groups. The experimental group received CPM + PT for 17 consecutive days after surgery, whereas the usual care group received the same treatment during the in-hospital phase (i.e. about four days), followed by PT alone (usual care) in the first two weeks after hospital discharge. From 18 days to three months after surgery, both groups received standardised PT. The primary focus of rehabilitation was functional recovery (e.g. ambulation) and regaining RoM in the knee. Prolonged use of CPM slightly improved short-term RoM in patients with limited RoM at the time of discharge after total knee arthroplasty when added to a semi-standard PT programme. Assessment at 6 weeks and three months after surgery found no long-term effects of this intervention Neither did we detect functional benefits of the improved RoM at any of the outcome assessments. Although results indicate that prolonged CPM use might have a small short-term effect on RoM, routine use of prolonged CPM in patients with limited RoM at hospital discharge should be reconsidered, since neither long-term effects nor transfer to better functional performance was detected.

Concomitant tricuspid valve surgery with mitral valve surgery is recommended for patients with severe functional tricuspid regurgitation (TR). However, the treatment for 2+ TR (mild TR) remains controversial. Here, we evaluated the long-term results of untreated 2+ TR in patients undergoing mitral valve surgery. We retrospectively reviewed the records of 96 patients with untreated 2+ TR among 885 patients who underwent mitral valve surgery from 2003 to 2010. Exclusion criteria were tricuspid valve surgery (TVS), emergency surgery, primary TR and pacemaker lead through the tricuspid valve. We assessed survival and freedom from heart failure. The freedom from 3+ (moderate) or 4+ (severe) TR was investigated by echocardiographic data at pre- and postoperative week 1, then at 1, 3, 5, 7 and 10 postoperative years, which were compared with those in patients who had 2+ TR preoperatively and underwent concomitant TVS in the same period (n = 47). The mean follow-up was 7.1 ± 2.7 years. There was no 30-day mortality. The survival rate was 97.5% at 5 years and 87.5% at 10 years. The independent risk factors for mortality were age (OR 1.2, P = 0.03) and left ventricular ejection fraction (OR 0.9, P = 0.03). Untreated 2+ TR improved transiently within the first postoperative year (P < 0.001), but progressed again in the mid- to long term. Freedom from ≥3+ TR was 64.2% at 5 years and 46.7% at 10 years, which was significantly lower than that from ≥3+ TR in patients who underwent concomitant TVS (P = 0.006). The independent risk factors for TR progression (≥3 + TR) were age (OR 1.1, P = 0.005), atrial fibrillation (OR 2.2, P = 0.04) and tricuspid annular diameter (TAD) index (mm/m(2); OR 1.1, P = 0.02). Receiver operating characteristic curves showed that the optimal TAD index cut-off value was 21.0 for long-term survival [area under the curve (AUC) = 0.72] and 21.2 for TR progression (AUC = 0.64). Although untreated, 2+ TR significantly improved after mitral valve surgery, it then progressed again in the mid- to long term. Therefore, concomitant TVS should be considered in patients with 2+ TR who have dilated tricuspid annulus or atrial fibrillation, if feasible. © The Author 2016.

Transformation from persistent to paroxysmal atrial fibrillation (AF) after ablation suggests modification of the underlying substrate. We examined the nature of initial arrhythmia recurrence in patients with nonparoxysmal AF undergoing antral pulmonary vein isolation and nonpulmonary vein trigger ablation and correlated recurrence type with long-term ablation efficacy after the last procedure. Three hundred and seventeen consecutive patients with persistent (n=200) and long-standing persistent (n=117) AF undergoing first ablation were included. AF recurrence was defined as early (≤6 weeks) or late (>6 weeks after ablation) and paroxysmal (either spontaneous conversion or treated with cardioversion ≤7 days) or persistent (lasting >7 days). During median follow-up of 29.8 (interquartile range: 14.8-49.9) months, 221 patients had ≥1 recurrence. Initial recurrence was paroxysmal in 169 patients (76%) and persistent in 52 patients (24%). Patients experiencing paroxysmal (versus persistent) initial recurrence were more likely to achieve long-term freedom off antiarrhythmic drugs (hazard ratio, 2.2; 95% confidence interval, 1.5-3.2; P<0.0001), freedom on/off antiarrhythmic drugs (hazard ratio, 2.5; 95% confidence interval, 1.6-3.8; P<0.0001), and arrhythmia control (hazard ratio, 5.2; 95% confidence interval, 2.9-9.2; P<0.0001) after last ablation. In patients with persistent and long-standing persistent AF, limited ablation targeting pulmonary veins and documented nonpulmonary vein triggers improves the maintenance of sinus rhythm and reverses disease progression. Transformation to paroxysmal AF after initial ablation may be a step toward long-term freedom from recurrent arrhythmia. © 2016 American Heart Association, Inc.

The impact of permanent pacemaker (PPM) on long-term clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) has not been studied. PPM may increase heart failure (HF) burden on patients undergoing PCI. We recruited consecutive patients undergoing PCI and carried out a nested case-control study. Patients with confirmed PPM undergoing first PCI were identified and matched by age and sex in 1:1 fashion to patients without PPM undergoing first PCI. Clinical data were collected and analyzed. The primary endpoint outcomes were all-cause mortality and hospitalization for HF. The final analysis included 156 patients. The mean follow-up period was 4.6 ± 2.9 years. The overall all-cause mortality was 21.15%, without significant difference between the 2 groups (21.79% vs 20.51%; P = 0.85). However, the rate of HF-related hospitalization was significantly higher in patients with PPM than in controls (26.92% vs 10.26%; P = 0.008). After adjustment for hypertension, type 2 diabetes mellitus, hyperlipidemia, chronic kidney disease, stroke, left ventricular ejection fraction, brain natriuretic peptide, and acute coronary syndrome (ACS), PCI patients with PPM were still associated with a greater hospitalization rate for HF (odds ratio: 4.31, 95% confidence interval: 0.94-19.80, P = 0.061). Further analysis in the ACS subgroup showed VVI-mode pacing enhanced the risk for HF-associated hospitalization (adjusted odds ratio: 8.27, 95% confidence interval: 1.37-49.75, P = 0.02). PPM has no effect on all-cause mortality in patients undergoing first PCI but significantly increases the HF-associated hospitalization rate, especially in ACS patients. © 2016 Wiley Periodicals, Inc.

This meta-analysis examined outcomes of smoking cessation interventions evaluated in 19 randomized controlled trials with individuals in current addictions treatment or recovery. Smoking and substance use outcomes at posttreatment and long-term follow-up (> or = 6 months) were summarized with random effects models. Intervention effects for smoking cessation were significant at posttreatment and comparable for participants in addictions treatment and recovery; however, intervention effects for smoking cessation were nonsignificant at long-term follow-up. Smoking cessation interventions provided during addictions treatment were associated with a 25% increased likelihood of long-term abstinence from alcohol and illicit drugs. Short-term smoking cessation effects look promising, but innovative strategies are needed for long-term cessation. Contrary to previous concerns, smoking cessation interventions during addictions treatment appeared to enhance rather than compromise long-term sobriety. Copyright 2004 APA.

To investigate the short-term outcomes of treatment utilizing an outpatient scoliosis- specific back school program in thirty-six patients with adolescent idiopathic scoliosis (AIS). Improved signs and symptoms of AIS have been reported in response to curve-patternspecific exercise therapy programs. Additional outcome studies are needed. Thirty-six patients with adolescent idiopathic scoliosis (AIS), 33 females and 3 males, completed a twenty-hour multimodal exercise program (Schroth Best Practice® - SBP) for five to seven days at Scoliosis 3DC(SM). Average age was 13.89 years and average Cobb angles were 36.92° thoracic and 33.92° lumbar. The sample was comprised of patients under treatment from August 2011 to February 2015 who never had scoliosis-related surgery and who were not undergoing brace treatment. SBP program components included physio-logic® exercises, mobilizations, activities of daily living (ADLs), 3-D Made Easy®, and Schroth exercises. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), chest expansion (CE), and angle of trunk rotation (ATR) were clinical parameters used to evaluate results of this outpatient scoliosis-specific exercise program. Highly significant improvements were noted in FVC, FEV1, CE and Scoliometer(TM) readings. A short-term outpatient SBP program was found to have a positive influence on FVC, FEV1, ATR, and CE. We will present long-term results in a subsequent study.

We perform a retrospective investigation of multi-decade trends in price and life-cycle cost (LCC) for home appliances in periods with and without energy efficiency (EE) standards and labeling polices. In contrast to the classical picture of the impact of efficiency standards, the introduction and updating of appliance standards is not associated with a long-term increase in purchase price; rather, quality-adjusted prices undergo a continued or accelerated long-term decline. In addition, long term trends in appliance LCCs—which include operating costs—consistently show an accelerated long term decline with EE policies. We also show that the incremental price of efficiency improvements has declinedmore » faster than the baseline product price for selected products. These observations are inconsistent with a view of EE standards that supposes a perfectly competitive market with static supply costs. These results suggest that EE policies may be associated with other forces at play, such as innovation and learning-by-doing in appliance production and design, that can affect long term trends in quality-adjusted prices and LCCs.« less

Electromagnetic fields used in physiotherapeutic treatment affect not only patients, but also physiotherapists, patients not undergoing treatment and electronic medical equipment. The aim of the work was to study the parameters of the electromagnetic fields of physiotherapeutic devices with respect to requirements regarding the protection of electronic devices, including medical implants, against electromagnetic intererence, and the protection of the general public (patients not undergoing treatment and bystanders), as well as medical personnel, against the health hazards caused by electromagnetic exposure. The spatial distribution of electric and magnetic field strength was investigated near 3 capacitive short-wave and 3 long-wave diathermies and 3 ultrasound therapy units, as along with the capacitive electric currents caused by electromagnetic field interaction in the upper limbs of the physiotherapists operating these devices. The physiotherapists' exposure to electromagnetic fields depends on the spatial organisation of the workspace and their location during treatment. Electric fields able to interfere with the function of electronic medical implants and in whic anyone not undergoing treatment should not be present were measured up to 150-200 cm away from active applicators of short-wave diathermy, and up to 40-45 cm away from long-wave diathermy ones. Electric fields in which workers should not be present were measured up to 30-40 cm away from the applicators and cables of active short-wave diathermy devices. A capacitive electric current with a strength exceeding many times the international recommendations regarding workers protection was measured in the wrist while touching applicators and cables of active short-wave diathermy devices. The strongest environmental electromagnetic hazards occur near short-wave diathermy devices, and to a lesser degree near long-wave diathermy devices, but were not found near ultrasound therapy units.

Most recent studies have proposed the paradoxical benefits of obesity in surgical populations. For patients who underwent transcatheter aortic valve implantation (TAVI) for aortic stenosis, the prognostic roles of obesity and high body mass index remain controversial. Therefore, the objective of this meta-analysis was to evaluate whether the 'obesity paradox' exists in patients undergoing TAVI. We searched in PubMed and EMBASE to identify the eligible articles. Odds ratios and hazard ratios with the corresponding 95% confidence intervals (CI) were adopted for synthesizing short-term and long-term survival outcomes, respectively. The level of heterogeneity and the publication bias between studies were also estimated. Finally, there were 16 studies with 12 330 patients who met the eligibility criteria and who were thus included in this review. When body mass index was analysed as a continuous variable, each increase of 1 kg/m2 was significantly associated with the lower 30-day mortality rate (odds ratio = 0.95; 95% CI = 0.93-0.97; P < 0.001) and better long-term overall survival (hazard ratio = 0.96; 95% CI = 0.94-0.97; P < 0.001) for patients undergoing TAVI. The obese patients had a significantly lower risk of 30-day mortality after TAVI than did normal patients (odds ratio = 0.69; 95% CI = 0.50-0.95; P = 0.024). Further analyses indicated that the obesity could be predictive of more favourable long-term overall survival of TAVI (hazard ratio = 0.84; 95% CI = 0.72-0.97; P = 0.021). However, we found no difference in procedural complications between the obese and normal patients. In conclusion, higher body mass index and obesity seem to have protective benefits on both short-term and long-term survival of TAVI patients. Current evidence suggests that the 'obesity paradox' may really exist in TAVI. © The Author 2017.

Surgical treatment of elderly patients with meningioma is has proved to be safe, especially when patients are selected using dedicated surgical scores. These scores take into account tumor size, edema, location and patient's co-morbidities. Neuropsychological functioning (NPF) of this kind of patients has been poorly studied in literature and it is not taken into account by these scores. Aim of our study was to describe the long-term outcome in terms of NPF of elderly patients undergoing surgery. Patients older than 70 years of age affected by intracranial meningioma and selected with the Clinical-Radiological Grading Score were included in our study. Neuropsychological testing was performed using a dedicated battery of tests before surgery, 3 and 12 months after surgery. Clinical, neurological and radiological outcomes were studied as well. Forty-one patients with a median age of 74 years were included in this study. Preoperatively only 1/41 patients showed a normal NPF with all tests scoring normally. Four out of 39 patients showed a complete neuropsychological recovery after 3 months; while 10/37 patients had a complete recovery after 12 months. NPF showed a trend of progressive improvement after surgery. Our study is the first experience reported in literature describing a long term follow-up in elderly patients after surgery for intracranial meningioma. In our series, surgery determined an improvement of NPF over time; especially with a low complication rate related to the selection of patients obtained through the CRGS. Further studies need to be performed in order to understand how brain edema, tumor size, volume and tumor location affect NPF in both short and long term.

Long-term results after liver resection for hilar cholangiocarcinoma are still not satisfactory. Previously, we described a survival advantage of patients who undergo combined right trisectionectomy and portal vein resection, a procedure termed "hilar en bloc resection." The present study was conducted to analyze its oncological effectiveness compared to conventional hepatectomy. During hilar en bloc resection, the extrahepatic bile ducts were resected en bloc with the portal vein bifurcation, the right hepatic artery, and liver segments 1 and 4 to 8. With this "no-touch" technique, preparation of the hilar vessels in the vicinity of the tumor was avoided. The long-term outcome of 50 consecutive patients who underwent curative (R0) hilar en bloc resection between 1990 and 2004 was compared to that of 50 consecutive patients who received curative conventional major hepatectomy for hilar cholangiocarcinoma (perioperative deaths excluded). The 1-, 3-, and 5-year survival rates after hilar en bloc resection were 87%, 70%, and 58%, respectively, which was significantly higher than after conventional major hepatectomy. In the latter group, 1-, 3-, and 5-year survival rates were 79%, 40%, and 29%, respectively (P = 0.021). Tumor characteristics were comparable in both groups. A high number of pT3 and pT4 tumors and patients with positive regional lymph nodes were present in both groups. Multivariate analysis identified hilar en bloc resection as an independent prognostic factor for long-term survival (P = 0.036). In patients with central bile duct carcinomas, hilar en bloc resection is oncologically superior to conventional major hepatectomy, providing a chance of long-term survival even in advanced tumors.

Although the release of cardiac biomarkers after percutaneous (PCI) or surgical revascularization (CABG) is common, its prognostic significance is not known. Questions remain about the mechanisms and degree of correlation between the release, the volume of myocardial tissue loss, and the long-term significance. Delayed-enhancement of cardiac magnetic resonance (CMR) consistently quantifies areas of irreversible myocardial injury. To investigate the quantitative relationship between irreversible injury and cardiac biomarkers, we will evaluate the extent of irreversible injury in patients undergoing PCI and CABG and relate it to postprocedural modifications in cardiac biomarkers and long-term prognosis. The study will include 150 patients with multivessel coronary artery disease (CAD) with left ventricle ejection fraction (LVEF) and a formal indication for CABG; 50 patients will undergo CABG with cardiopulmonary bypass (CPB); 50 patients with the same arterial and ventricular condition indicated for myocardial revascularization will undergo CABG without CPB; and another 50 patients with CAD and preserved ventricular function will undergo PCI using stents. All patients will undergo CMR before and after surgery or PCI. We will also evaluate the release of cardiac markers of necrosis immediately before and after each procedure. Primary outcome considered is overall death in a 5-year follow-up. Secondary outcomes are levels of CK-MB isoenzyme and I-Troponin in association with presence of myocardial fibrosis and systolic left ventricle dysfunction assessed by CMR. The MASS-V Trial aims to establish reliable values for parameters of enzyme markers of myocardial necrosis in the absence of manifest myocardial infarction after mechanical interventions. The establishments of these indices have diagnostic value and clinical prognosis and therefore require relevant and different therapeutic measures. In daily practice, the inappropriate use of these necrosis markers has led to misdiagnosis and therefore wrong treatment. The appearance of a more sensitive tool such as CMR provides an unprecedented diagnostic accuracy of myocardial damage when correlated with necrosis enzyme markers. We aim to correlate laboratory data with imaging, thereby establishing more refined data on the presence or absence of irreversible myocardial injury after the procedure, either percutaneous or surgical, and this, with or without the use of cardiopulmonary bypass.

Quantitative Systems Pharmacology Model of NO Metabolome and Methemoglobin Following Long-Term Infusion of Sodium Nitrite in Humans

PubMed Central

Vega-Villa, K; Pluta, R; Lonser, R; Woo, S

2013-01-01

A long-term sodium nitrite infusion is intended for the treatment of vascular disorders. Phase I data demonstrated a significant nonlinear dose-exposure-toxicity relationship within the therapeutic dosage range. This study aims to develop a quantitative systems pharmacology model characterizing nitric oxide (NO) metabolome and methemoglobin after sodium nitrite infusion. Nitrite, nitrate, and methemoglobin concentration–time profiles in plasma and RBC were used for model development. Following intravenous sodium nitrite administration, nitrite undergoes conversion in RBC and tissue. Nitrite sequestered by RBC interacts more extensively with deoxyhemoglobin, which contributes greatly to methemoglobin formation. Methemoglobin is formed less-than-proportionally at higher nitrite doses as characterized with facilitated methemoglobin removal. Nitrate-to-nitrite reduction occurs in tissue and via entero-salivary recirculation. The less-than-proportional increase in nitrite and nitrate exposure at higher nitrite doses is modeled with a dose-dependent increase in clearance. The model provides direct insight into NO metabolome disposition and is valuable for nitrite dosing selection in clinical trials. PMID:23903463

Exposure to long-term stress has a variety of consequences on the brain and cognition. Few studies have examined the influence of long-term stress on event related potential (ERP) indices of error processing. The current study investigated how long-term academic stress modulates the error related negativity (Ne or ERN) and the error positivity (Pe) components of error processing. Forty-one male participants undergoing preparation for a major academic examination and 20 non-exam participants completed a Go-NoGo task while ERP measures were collected. The exam group reported higher perceived stress levels and showed increased Pe amplitude compared with the non-exam group. Participants' rating of the importance of the exam was positively associated with the amplitude of Pe, but these effects were not found for the Ne/ERN. These results suggest that long-term academic stress leads to greater motivational assessment of and higher emotional response to errors. Copyright © 2014 Elsevier B.V. All rights reserved.

Aim To review the current evidence concerning the long-term harmful effects of premature or early menopause, and to discuss some of the clinical implications. Material and methods Narrative review of the literature. Results Women undergoing premature or early menopause, either following bilateral salpingo-oophorectomy or because of primary ovarian insufficiency, experience the early loss of estrogen and other ovarian hormones. The long-term consequences of premature or early menopause include adverse effects on cognition, mood, cardiovascular, bone, and sexual health, as well as an increased risk of early mortality. The use of hormone therapy has been shown to lessen some, although not all of these risks. Therefore, multiple medical societies recommend providing hormone therapy at least until the natural age of menopause. It is important to individualize hormone therapy for women with early estrogen deficiency, and higher dosages may be needed to approximate physiological concentrations found in premenopausal women. It is also important to address the psychological impact of early menopause and to review the options for fertility and the potential need for contraception, if the ovaries are intact. Conclusions Women who undergo premature or early menopause should receive individualized hormone therapy and counseling. PMID:25845383

Enhanced recovery after surgery (ERAS) programmes and laparoscopic techniques both provide short-term benefits to patients undergoing colorectal cancer surgery. ERAS protocol compliance may improve long-term survival in those undergoing open colorectal resection but as laparoscopic data has not been reported. Therefore, we aimed to investigate the impact of the combination of laparoscopy and ERAS management on 5-year overall survival. A dedicated prospectively populated colorectal cancer surgery database was reviewed. Patient inclusion criteria were biopsy-proven colorectal adenocarcinoma, undergoing elective surgery undertaken with curative intent. All patients were managed within an established ERAS programme and routinely followed up for 5 years. Overall survival was measured using the log-rank Kaplan-Meier method at 5 years. Eight hundred fifty-four patients met the inclusion criteria. Four hundred eighty-one (56%) cases were laparoscopic with 98 patients (20%) requiring conversion. There were no differences in patient or tumour demographics between the surgical groups. Median ERAS protocol compliance was 93% (range 53-100%). Five-year overall survival was superior in laparoscopic cases compared with that of converted and open surgery (78 vs 68 vs 70%, respectively, p < 0.007). An open approach (HR 1.55, 95%CI 1.16-2.06, p = 0.002) and delayed hospital discharge (> 7 days, HR 1.5, 95%CI 1.13-1.9, p = 0.003) were the only modifiable risk factors associated with poor survival. The use of a laparoscopic approach with enhanced recovery after surgery management appears to have long-term survival benefits following colorectal cancer resection.

Matrix effects, which represent an important issue in liquid chromatography coupled to mass spectrometry or tandem mass spectrometry detection, should be closely assessed during method development. In the case of quantitative analysis, the use of stable isotope-labelled internal standard with physico-chemical properties and ionization behaviour similar to the analyte is recommended. In this paper, an example of the choice of a co-eluting deuterated internal standard to compensate for short-term and long-term matrix effect in the case of chiral (R,S)-methadone plasma quantification is reported. The method was fully validated over a concentration range of 5-800 ng/mL for each methadone enantiomer with satisfactory relative bias (-1.0 to 1.0%), repeatability (0.9-4.9%) and intermediate precision (1.4-12.0%). From the results obtained during validation, a control chart process during 52 series of routine analysis was established using both intermediate precision standard deviation and FDA acceptance criteria. The results of routine quality control samples were generally included in the +/-15% variability around the target value and mainly in the two standard deviation interval illustrating the long-term stability of the method. The intermediate precision variability estimated in method validation was found to be coherent with the routine use of the method. During this period, 257 trough concentration and 54 peak concentration plasma samples of patients undergoing (R,S)-methadone treatment were successfully analysed for routine therapeutic drug monitoring.

Edifoligide, an E2F transcription factor decoy, does not prevent vein graft failure or adverse clinical outcomes at 1 year in patients undergoing coronary artery bypass grafting (CABG). We compared the 5-year clinical outcomes of patients in PREVENT IV treated with edifoligide and placebo to identify predictors of long-term clinical outcomes. A total of 3,014 patients undergoing CABG with at least 2 planned vein grafts were enrolled. Kaplan-Meier curves were generated to compare the long-term effects of edifoligide and placebo. A Cox proportional hazards model was constructed to identify factors associated with 5-year post-CABG outcomes. The main outcome measures were death, myocardial infarction (MI), repeat revascularization, and rehospitalization through 5 years. Five-year follow-up was complete in 2,865 patients (95.1%). At 5 years, patients randomized to edifoligide and placebo had similar rates of death (11.7% and 10.7%, respectively), MI (2.3% and 3.2%), revascularization (14.1% and 13.9%), and rehospitalization (61.6% and 62.5%). The composite outcome of death, MI, or revascularization occurred at similar frequency in patients assigned to edifoligide and placebo (26.3% and 25.5%, respectively; hazard ratio 1.03 [95% CI 0.89-1.18], P = .721). Factors associated with death, MI, or revascularization at 5 years included peripheral and/or cerebrovascular disease, time on cardiopulmonary bypass, lung disease, diabetes mellitus, and congestive heart failure. Up to a quarter of patients undergoing CABG will have a major cardiac event or repeat revascularization procedure within 5 years of surgery. Edifoligide does not affect outcomes after CABG; however, common identifiable baseline and procedural risk factors are associated with long-term outcomes after CABG. Copyright © 2012 Mosby, Inc.

Although there is now considerable experience in obtaining sperm from a cadaver, there is little or no published data regarding pregnancy, birth and long-term childhood health and development outcomes when posthumous sperm is used in in vitro fertilisation (IVF). We report the results from treatment of four women undergoing IVF treatment using posthumously acquired human sperm from their deceased partners. In all cases, testicular tissue was obtained in a mortuary setting, and the duration from death to posthumous sperm retrieval ranged from 12 to 48 h. The age of women treated ranged from 31 to 41 years. Fertilization rates ranged from 40 to 100%. Singleton pregnancies were obtained for each of the four women. One pregnancy was complicated by preterm birth at 31 weeks; the other three delivered at term. One baby was growth restricted but morphologically normal; the other children had term birthweights in the normal range. All four children were have shown normal health and developmental outcomes, with the follow-up ranging from 1 to 7 years. © The Author 2015.

OBJECTIVE Cushing disease is caused by a pituitary micro- or macroadenoma that hypersecretes adrenocorticotropic hormone (ACTH), resulting in hypercortisolemia. For decades, transsphenoidal resection (TSR) has been an efficacious treatment but with certain limitations, namely precise tumor localization and complete excision. The authors evaluated the novel use of a double-antibody sandwich assay for the real-time quantitation of ACTH in resected pituitary specimens with the goals of augmenting pathological diagnosis and ultimately improving long-term patient outcome. METHODS This study involved a retrospective review of records and an analysis of assay values, pathology slides, and MRI studies of patients with Cushing disease who had undergone TSR in the period from 2009 to 2014 and had at least 1 year of follow-up in coordination with an endocrinologist. In the operating room, biopsy specimens from the patients had been analyzed for tissue ACTH concentration. Additional samples were simultaneously sent for frozen-section pathological analysis. The ACTH assay performance was compared against pathology assessments of surgical tumor samples using receiver operating characteristic (ROC) analysis and against pre- and postoperative MRI studies. RESULTS Fourteen patients underwent TSR with guidance by ACTH-antibody assay and pathological assessment of 127 biopsy samples and were followed up for an average of 3 years. The ACTH threshold for discriminating adenomatous from normal tissue was 290,000 pg/mg of tissue, based on jointly maximized sensitivity (95.0%) and specificity (71.3%). Lateralization discordance between preoperative MRI studies and surgical visualization was noted in 3 patients, confirming the impression that MRI alone may not achieve optimal localization. A majority of the patients (85.7%) attained long-term disease remission based on urinary free cortisol levels, plasma cortisol levels, and long-term corticosteroid therapy. Comparisons of patient-months of remission and treatment failure showed that the remission rate in the study sample statistically exceeds the rate in historical controls (71.9%; p = 0.0007, Fisher's exact test). Long-term unexpected hormonal deficiencies were statistically similar between study patients (29%) and those in a meta-analysis (25%; p = 0.7596, Fisher's exact test). CONCLUSIONS These preliminary findings reflect the promising potential of tissue-based ACTH-antibody-guided assay for improving the cure rates of Cushing disease patients undergoing TSR. Further studies with larger sample sizes, further refinements of assay interpretation, and longer-term follow-ups are needed.

A permanent pacemaker (PPM) with dual chamber pacing (DDD) offers atrioventricular synchronization for patients with atrioventricular block (AVB). Single lead atrial synchronous ventricular pacing mode (VDD) is an alternative, but there are concerns about its efficacy and risk of atrial undersensing. Whether VDD can be a good alternative in patients with AVB remains unknown. The aim of the present study was to compare the long-term risk of mortality of VDD with DDD pacing.A total of 207 patients undergoing PPM implantations for AVB with VDD mode were enrolled from 2000 to 2013. Another 828 age- and sex-matched patients undergoing DDD implantations during the same period of time were selected as the control group in a 1 to 4 ratio. The study endpoint was mortality.A total of 1035 patients (64.3% male) were followed up for 46.5 ± 43.2 months. The mean ages were 75.0 years for VDD, and 74.9 years for DDD. The Kaplan-Meier survival analysis showed no significant difference in long-term survival between the VDD and DDD groups (log-rank P = 0.313). After adjustment for baseline characteristics, the VDD and DDD groups had a similar long-term prognosis with an adjusted hazard ratio of 0.875 (P = 0.445). Further analyses for the risk of cardiovascular and noncardiovascular deaths also showed no significant differences between the 2 groups.The long-term prognosis of VDD mode is comparable to that of DDD mode. Single lead VDD can be considered as an alternative choice in patients with AVB without sinus nodal dysfunction.

INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39–79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p=0.005 and p=0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p=0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

Stereotactic amygdalotomy has been utilized as a surgical treatment for severe aggressive behavioral disorders. Several clinical studies have been reported since the first description of the procedure. In the current study, the authors reviewed the literature and evaluated the surgical results, neuropsychological outcome, and complication rate in patients who had undergone stereotactic amygdalotomy for severe aggressive behavioral disorders. The PubMed database was searched using the following terms: "amygdalotomy," "amygdalectomy," "amygdaloidectomy," "psychosurgery," "aggressive disorder," and "behavioral disorder." Clinical series with more than 5 patients undergoing stereotactic amygdalotomy for aggressive or other behavioral disorders were included in this review. The surgical technique, anatomical target, improvement in psychiatric symptomatology, postoperative employment and social rehabilitation, postoperative neurocognitive function, procedure-related complications, and long-term follow-up were evaluated. Thirteen clinical studies met our inclusion criteria. Reported postoperative improvement in aggressive behavior varied between 33 and 100%. Procedure-related complication rates ranged from 0 to 42%, whereas the mortality rate was as high as 3.8%. In the majority of the reviewed clinical series, the performance of stereotactic amygdalotomy did not compromise a patient's learning, language, and intellectual capabilities. The long-term follow-up, although very limited, revealed that initially observed improvement was maintained in most cases. Stereotactic amygdalotomy can be considered a valid surgical treatment option for carefully selected patients with medically refractory aggressive behavioral disorders. Recent advances in imaging and stereotactic navigation can further improve outcome and minimize the complication rate associated with this psychosurgical procedure.

Our goal was to explore the effects of lymphedema on long-term adjustment among breast cancer survivors, in terms of functioning in important life environments. Limb volume measurements and psychosocial survey data were collected from women shortly after undergoing surgical intervention for breast cancer and annually thereafter. A subset of these women were selected for the current study because they had preoperative limb volume measurement data, which is best suited to determine presence and severity of lymphedema. Our final sample of 61 women had both the arm measurements (preoperative and 5-year) and survey data (baseline and 5-year) needed for this study, which comprises a secondary cross-sectional analysis of longitudinal data. A correlational approach was used to explore associations among lymphedema (presence, severity, and whether the participant met the criteria for lymphedema at any assessment point since their treatment for breast cancer) and outcome variables (physical functioning, vocational functioning, social functioning, domestic functioning, and sexual functioning). Each of the three measures of lymphedema was significantly correlated with domestic functioning, but not with functioning in other common environments. Long-term breast cancer survivors are at risk for developing secondary conditions, such as lymphedema, to which they must learn to adjust and adapt. Lymphedema may increase risk for compromised functioning in everyday environments, a problem which lies at the heart of rehabilitation. Breast cancer survivorship, therefore, fits well within the scope of a rehabilitation framework. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Hodgkin lymphoma (HL) is a highly curable disease; < 80% of patients will achieve long-term survival. Positron emission tomography-computed tomography (PET-CT) has played a major role in the evaluation of both disease staging and response and has become an essential component in tailoring patients' treatment. We report the effect of integrating PET-CT into the management of HL in Lebanon. We analyzed the data regarding the usage of PET-CT at diagnosis, during treatment (interim PET), and at the end of treatment. We also analyzed the PET-CT findings from 2009 to 2015. The first PET-CT system was introduced in Lebanon in April 2002 but was not used for the evaluation of HL. Early in 2009, we started to incorporate PET-CT into the treatment of HL. By the end of 2009, 70% of patients were undergoing PET-CT at diagnosis and at the end of treatment. This proportion remained constant until 2013, when an increase occurred, with ≤ 94% of patients undergoing PET-CT at diagnosis. The usage of CT at diagnosis decreased significantly from 70% before 2009 to 52% after 2015. In contrast, CT usage at the end of treatment has fluctuated from 10% in 2009 to 0% in 2012, 2013, and 2014 and 11.76% in 2015. Functional imaging techniques are increasing in popularity compared with anatomic imaging. The usage of PET-CT has emerged as a highly valuable staging and follow-up method in the treatment of HL 8 years after the introduction of PET in Lebanon. PET was used first to improve the staging, then to evaluate the treatment response, and, recently, to tailor therapy according to the response. Copyright © 2017 Elsevier Inc. All rights reserved.

To compare the reproductive outcomes of Yqh+-carrying and control couples undergoing IVF/ICSI treatments. Retrospective analysis of 72 Yqh+ carriers and 986 Yqh+ non-carriers undergoing their first cycle of ART in a single centre between August 2005 and May 2011. Yqh+ carrying couples had significantly worse reproductive outcomes compared with control couples undergoing IVF treatment. There were a significantly higher cancellation rate (20.69% vs 7.9%; P<0.05; OR, 3.03; CI, 1.18-7.79) and a significant lower fertilisation rate (50.05% vs 66.01%; P<0.05; OR, 0.61; CI, 0.49-0.57), implantation rate (8.33% vs 20.87%; P<0.05; OR, 0.35; CI, 0.14-0.87), good quality embryo ratio (44.70% vs 57.89%; P<0.05; OR, 0.59; CI, 0.43-0.80) and clinical pregnancy rate (17.39% vs 39.59%; P<0.05; OR, 0.32; CI, 0.11-0.96) in Yqh+ group compared with control group undergoing IVF treatment. Yqh+ carrying couples had similar reproductive outcomes compared with control couples undergoing ICSI treatment. The Y chromosome polymorphic variant Yqh+ most likely plays a role in infertility. Yqh+ couples with poor reproductive outcomes in IVF treatment can be advised to undergo ICSI to improve their reproductive results in the next cycle. Copyright © 2012 Elsevier Ireland Ltd.

Purpose: To investigate long-term swallowing function in oropharyngeal cancer patients treated with intensity-modulated radiotherapy (IMRT), and to identify novel dose-limiting criteria predictive for dysphagia. Methods and Materials: Thirty-one patients with Stage IV oropharyngeal squamous carcinoma enrolled on a Phase II trial were prospectively evaluated by modified barium swallow studies at baseline, and 6, 12, and 24 months post-IMRT treatment. Candidate dysphagia-associated organs at risk were retrospectively contoured into original treatment plans. Twenty-one (68%) cases were base of tongue and 10 (32%) were tonsil. Stage distribution was T1 (12 patients), T2 (10), T3 (4), T4 (2), and TX (3), and N2more » (24), N3 (5), and NX (2). Median age was 52.8 years (range, 42-78 years). Thirteen patients (42%) received concurrent chemotherapy during IMRT. Thirteen (42%) were former smokers. Mean dose to glottic larynx for the cohort was limited to 18 Gy (range, 6-39 Gy) by matching IMRT to conventional low-neck fields. Results: Dose-volume constraints (V30 < 65% and V35 < 35% for anterior oral cavity and V55 < 80% and V65 < 30% for high superior pharyngeal constrictors) predictive for objective swallowing dysfunction were identified by univariate and multivariate analyses. Aspiration and feeding tube dependence were observed in only 1 patient at 24 months. Conclusions: In the context of glottic laryngeal shielding, we describe candidate oral cavity and superior pharyngeal constrictor organs at risk and dose-volume constraints associated with preserved long-term swallowing function; these constraints are currently undergoing prospective validation. Strict protection of the glottic larynx via beam-split IMRT techniques promises to make chronic aspiration an uncommon outcome.« less

Is screen-and-treat approach suited for screening and management of precancerous cervical lesions in Sub-Saharan Africa?

PubMed

Fokom-Domgue, Joël; Vassilakos, Pierre; Petignat, Patrick

2014-08-01

The World Health Organization guidelines for screening and management of cervical precancerous lesions updated in 2013 made an emphasis on the use of the 'screen-and-treat' approach for cervical cancer prevention. In order to facilitate scaling-up in low income settings, most of these screen-and-treat strategies do not involve confirmatory biopsy. This yields a certain rate of overtreatment. In other words, a majority of people undergoing screen-and-treat intervention who are treated does not necessarily benefit from the treatment. Therefore, the issue of potential short term and long term complications of the recommended treatment procedures (cryotherapy and Loop Electrosurgical Excision Procedure) arises. This question has seldom been studied in resource poor countries, particularly in Sub-Saharan Africa where Human Immunodeficiency Virus infection is rampant in an epidemic fashion and where the procreative capacities are socially rewarding for women. We draw the attention of the scientific community and policy makers to the fact that the lack of evidence supporting the safety of these treatment procedures in African populations may have an impact on the acceptability of these strategies and therefore on the effectiveness of screening programs.

Purpose To identify the main issues of importance when living with long-term conditions to refine a conceptual framework for informing the item development of a patient-reported outcome measure for long-term conditions. Materials and methods Semi-structured qualitative interviews (n=48) were conducted with people living with at least one long-term condition. Participants were recruited through primary care. The interviews were transcribed verbatim and analyzed by thematic analysis. The analysis served to refine the conceptual framework, based on reviews of the literature and stakeholder consultations, for developing candidate items for a new measure for long-term conditions. Results Three main organizing concepts were identified: impact of long-term conditions, experience of services and support, and self-care. The findings helped to refine a conceptual framework, leading to the development of 23 items that represent issues of importance in long-term conditions. The 23 candidate items formed the first draft of the measure, currently named the Long-Term Conditions Questionnaire. Conclusion The aim of this study was to refine the conceptual framework and develop items for a patient-reported outcome measure for long-term conditions, including single and multiple morbidities and physical and mental health conditions. Qualitative interviews identified the key themes for assessing outcomes in long-term conditions, and these underpinned the development of the initial draft of the measure. These initial items will undergo cognitive testing to refine the items prior to further validation in a survey. PMID:27621678

New frontiers in developmental neuropharmacology: Can long-term therapeutic effects of drugs be optimized through carefully timed early intervention?

PubMed Central

Andersen, Susan L.; Navalta, Carryl P.

2010-01-01

Our aim is to present a working model that may serve as a valuable heuristic to predict enduring effects of drugs when administered during development. Our primary tenet is that a greater understanding of neurodevelopment can lead to improved treatment that intervenes early in the progression of a given disorder and prevents symptoms from manifesting. The immature brain undergoes significant changes during the transitions between childhood, adolescence, and adulthood. Such changes in innervation, neurotransmitter levels, and their respective signaling mechanisms have profound and observable changes on typical behavior, but also increase vulnerability to psychiatric disorders when the maturational process goes awry. Given the remarkable plasticity of the immature brain to adapt to its external milieu, preventive interventions may be possible. We intend for this review to initiate a discussion of how currently used psychotropic agents can influence brain development. Drug exposure during sensitive periods may have beneficial long-term effects, but harmful delayed consequences may be possible as well. Regardless of the outcome, this information needs to be used to improve or develop alternative approaches for the treatment of childhood disorders. With this framework in mind, we present what is known about the effects of stimulants, antidepressants, and antipsychotics on brain maturation (including animal studies that use more clinically-relevant dosing paradigms or relevant animal models). We endeavor to provocatively set the stage for altering treatment approaches for improving mental health in non-adult populations. PMID:21309771

Towards accurate localization: long- and short-term correlation filters for tracking

NASA Astrophysics Data System (ADS)

Li, Minglangjun; Tian, Chunna

2018-04-01

Visual tracking is a challenging problem, especially using a single model. In this paper, we propose a discriminative correlation filter (DCF) based tracking approach that exploits both the long-term and short-term information of the target, named LSTDCF, to improve the tracking performance. In addition to a long-term filter learned through the whole sequence, a short-term filter is trained using only features extracted from most recent frames. The long-term filter tends to capture more semantics of the target as more frames are used for training. However, since the target may undergo large appearance changes, features extracted around the target in non-recent frames prevent the long-term filter from locating the target in the current frame accurately. In contrast, the short-term filter learns more spatial details of the target from recent frames but gets over-fitting easily. Thus the short-term filter is less robust to handle cluttered background and prone to drift. We take the advantage of both filters and fuse their response maps to make the final estimation. We evaluate our approach on a widely-used benchmark with 100 image sequences and achieve state-of-the-art results.

Oesophageal achalasia is well-recognized but relatively rare in children, occasionally appearing as the "triple A" syndrome (with adrenal insufficiency and alacrima). Treatment modalities, as in adult practice, are not curative, often needing further interventions and spurring the search for better management. The outcome for syndromic variants is unknown. We sought to define the efficacy of treatments for children with achalasia with and without triple A syndrome. We conducted a retrospective analysis of presentation and outcomes for 42 children with achalasia presenting over three decades to a major pediatric referral center. Long term impact of the diagnosis was assessed by questionnaire. We identified 42 children including six with triple A syndrome. The median overall age at diagnosis was 10.8 years and median follow-up 1593 days. Initial Heller myotomy in 17 required further interventions in 11 (65%), while initial treatment with botulinum toxin (n = 20) was ultimately followed by myotomy in 17 (85%). Ten out of 35 patients who underwent myotomy required a repeat myotomy (29%). Patients with triple A syndrome developed symptoms earlier, but had delayed diagnosis, were more underweight at diagnosis and at last follow up. Questionnaire results suggested a significant long term deleterious impact on the quality of life of children and their families. Many children with achalasia relapse after initial treatment, undergoing multiple, different procedures, despite which symptoms persist and impact on quality of life. Symptoms develop earlier in patients with triple A syndrome, but the diagnosis is delayed and this has substantial nutritional impact. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Carotid artery ligation (CAL) is used to treat large and complex intracranial aneurysms. However, little is known about long-term survival and causes of death in patients who undergo the procedure. This study was intended to evaluate if patients who have undergone CAL have long-term excess mortality and what the causes of death are. All patients were treated at Helsinki University Hospital between 1937 and 2009. Patients who had undergone CAL and survived ≥1 year after the procedure were included in the cohort. Follow-up was until death or 2015 (2711 patient-years). Causes of death were reviewed and relative survival ratios calculated using the Ederer II method and a matched population. There was 12% excess mortality in all patients 20 years after CAL and 22% after 30 years. A higher proportion of the patients who had subarachnoid hemorrhage (SAH) died during follow-up compared with unruptured patients undergoing CAL. Cardiovascular disease and cerebrovascular accident were the leading causes of death. Patients with unruptured aneurysms did not experience as much excess mortality as those who had an SAH. The higher proportion of deaths observed in ruptured patients may be partly because of long-term excess mortality conferred by the SAH itself or SAH risk factors. Although the entire population did display excess mortality compared with the general population, this may be because of shared risk factors for aneurysm development and rupture and the cause of death.

Fanconi anemia (FA) is characterized by congenital malformations, progressive bone marrow failure, and predisposition to malignancy. Hematopoietic stem cell transplantation is used to treat FA, and best results are attained with sibling donors who are human leukocyte antigen (HLA) identical matches. Preimplantation genetic diagnosis (PGD) offers parents of an affected child the opportunity to have an unaffected child who is an HLA match. While some research has investigated parents' experiences during the PGD process, no published studies specifically address factors influencing their decision-making process and long-term interpersonal outcomes. The aims of this study are to: (1) examine parents' expectations and the influence of media, bioethics, and religion on their decision to undergo PGD; (2) examine parents' social support and emotional experiences during their PGD process; and (3) characterize long-term effects of PGD on relationship dynamics (partner, family, friends), others' attitudes, and parental regret. Nine parents participated in semi-structured interviews. Thematic analysis revealed their decision to use PGD was variously influenced by media, bioethics, and religion, in particular, affecting parents' initial confidence levels. Moreover, the PGD process was emotionally complex, with parents desiring varying amounts and types of support from different sources at different times. Parents reported others' attitudes towards them were similar or no different than before PGD. Parental regret regarding PGD was negligible. Results of this study will promote optimization of long-term care for FA families.

Immunomodulatory effects of macrolide antibiotics - part 2: advantages and disadvantages of long-term, low-dose macrolide therapy.

2011-01-01

The available evidence for long-term, low-dose treatment with 14- and 15-membered ring macrolides in non-cystic fibrosis (CF) bronchiectasis, COPD, chronic sinusitis, and asthma is reviewed with special attention to possible adverse effects and the emergence of resistance during long-term macrolide treatment. Macrolide maintenance therapy has been proven to be of benefit in diffuse panbronchiolitis and CF, presumably due to an anti-inflammatory mechanism of action in addition to its direct antimicrobial effect. Solid evidence to justify this treatment regimen for non-CF bronchiectasis, asthma, or sinusitis is still lacking, although a beneficial effect of long-term macrolide therapy has been found in small clinical trials on these subjects. Data from randomized trials of long-term macrolide treatment in COPD are conflicting. A sufficiently long duration of treatment and the careful selection of patients appears to be crucial. Aside from its beneficial effects, possible side effects of macrolide treatment should be taken into account, the most important of these being gastrointestinal upset and cardiac arrhythmias. Development of macrolide resistance among respiratory pathogens is very common during long-term macrolide treatment. Whether this finding is clinically significant is a matter of debate.

We reviewed the long-term outcomes in men undergoing permanent prostate brachytherapy with a focus on those presenting before age 60 years. Between 1992 and 2005 a total of 2,119 patients with clinical stage T1-T2, N0, M0 prostate cancer treated with permanent prostate brachytherapy were included in this study. Treatment regimens consisted of permanent prostate brachytherapy with or without hormone therapy, permanent prostate brachytherapy with external beam radiotherapy, or all 3 modalities. Biochemical recurrence was defined using the Phoenix definition. Multivariate analysis was performed to determine if age and/or other clinicopathological features were associated with disease progression. The Kaplan-Meier method was used to calculate rates of freedom from progression with the log rank test to compare patients younger than 60 vs 60 years or older. Median followup was 56.1 months. In the study population 237 patients were younger than 60 years at diagnosis (11%). The 5 and 10-year freedom from progression rates were 90.1% and 85.6%, respectively, for the entire population. Multivariate analysis demonstrated that prostate specific antigen (p <0.01), biopsy Gleason score (p <0.0001) and year of treatment (p <0.001) were associated with freedom from progression while age (p = 0.95) and clinical stage (p = 0.11) were not. There was no significant difference in freedom from progression between men younger than 60, or 60 years or older (log rank p = 0.46). In the younger cohort the 10-year freedom from progression for patients presenting with low, intermediate and high risk disease was 91.3%, 80.0% and 70.2% compared to 91.8%, 83.4% and 72.1%, respectively, for men 60 years or older. Our long-term results confirm favorable outcomes after permanent prostate brachytherapy in men younger than 60 years. Outcomes are impacted by disease related risk factors but not by age or clinical stage. Definitive treatment options for younger men with clinically localized prostate cancer should include permanent prostate brachytherapy.

Comparison of outcomes of laparoscopic Heller myotomy versus per-oral endoscopic myotomy for management of achalasia

Achalasia is a rare disorder that has several treatment options. The gold standard of treatment is a surgical myotomy called a laparoscopic Heller myotomy (LHM). More recently, an endoscopic myotomy has become an option as well, called per-oral endoscopic myotomy (POEM). An achalasia registry was queried for patients undergoing either LHM or POEM at Baylor University Medical Center at Dallas. Patient demographics, preoperative and postoperative data points, and Eckardt scores were collected. The patients were further stratified into their follow-up intervals, immediate postoperative and long-term follow-up, to assess surgical success. A subset analysis was done for success of treatment for patients who had redo surgery versus those undergoing the procedure for the first time. There were 12 patients in the POEM group and 11 patients in the LHM group. Both groups demonstrated mean lower esophageal sphincter pressures with failure to relax. Procedure length and hospital length of stay were similar between the two groups. There were three adverse events in each group, but none altered the patient's postoperative clinical course. Eckardt scores, used to assess success of the surgery, were 82% for POEM patients and 66% for LHM patients after 6 months. The outcomes for POEM and LHM in our early experience are similar to those reported in the literature for high-volume centers managing achalasia. PMID:28966450

This is a retrospective cohort comparative study of all patients who underwent instrumented spine surgery at a single institution. To compare the rate of surgical site infection (SSI) between the treatment (vancomycin) and the control group (no vancomycin) in patients undergoing instrumented spine surgery. SSI after spine surgery is a dreaded complication associated with increased morbidity and mortality. Prophylactic intraoperative local vancomycin powder to the wound has been recently adopted as a strategy to reduce SSI but results have been variable. In the present study, there were 117 (30%) patients in the treatment group and 272 (70%) patients in the comparison cohort. All patients received identical standard operative and postoperative care procedures based on protocolized department guidelines. The present study compared the rate of SSI with and without the use of prophylactic intraoperative local vancomycin powder in patients undergoing various instrumented spine surgery, adjusted for confounders. The overall rate of SSI was 4.7% with a decrease in infection rate found in the treatment group (0.9% vs. 6.3%). This was statistically significant (P = 0.049) with an odds ratio of 0.13 (95% confidence interval 0.02-0.99). The treatment group had a significantly shorter onset of infection (5 vs. 16.7 days; P < 0.001) and shorter duration of infection (8.5 vs. 26.8 days; P < 0.001). The most common causative organism was Pseudomonas aeruginosa (35.2%). Patient diagnosis, surgical approach, and intraoperative blood loss were significant risk factors for SSI after multivariable analysis. Prophylactic Intraoperative local vancomycin powder reduces the risk and morbidity of SSI in patients undergoing instrumented spine surgery. P. aeruginosa infection is common in the treatment arm. Future prospective randomized controlled trials in larger populations involving other spine surgeries with a long-term follow-up duration are recommended. 3.

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

This study aimed to assess sinonasal outcomes in patients with aspirin exacerbated respiratory disease (AERD) undergoing aspirin desensitization following endoscopic sinus surgery (ESS). Case series with chart review. University hospital. A retrospective review of sinonasal outcomes was conducted for 30 AERD patients undergoing aspirin desensitization and maintenance therapy following ESS. Sinonasal outcomes were prospectively assessed by the Sinonasal Outcomes Test-22 (SNOT-22) and endoscopic polyp grading system. Data were collected preoperatively, 1 and 4 weeks postsurgery (before desensitization), and 1, 6, 12, 18, 24, and 30 months after aspirin desensitization. Twenty-eight of 30 patients (93.3%) successfully completed aspirin desensitization, whereas 2 of 30 (6.7%) were unable to complete desensitization due to respiratory intolerance. Of the 21 patients who successfully completed a minimum of 24 weeks of follow-up, 20 (95.2%) patients demonstrated sustained endoscopic and symptomatic improvement for a median follow-up period of 33 months. After surgical treatment but before desensitization, patients experienced significant reductions in SNOT-22 and polyp grade scores. In the first 6 months after aspirin desensitization, patients experienced further significant reductions in SNOT-22 scores, whereas polyp grade remained stable. The improvements in symptom endoscopic scores were preserved throughout the follow-up period after desensitization. No patients required additional sinus surgery. One patient had to discontinue aspirin therapy due to gastrointestinal side effects. No other adverse reactions to aspirin were noted. Aspirin desensitization following ESS appears to be a well-tolerated and effective adjunctive therapy for long-term control of nasal polyposis in patients with AERD. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Myasthenia gravis is an autoimmune neuromuscular disorder. There are several treatment options, including symptomatic treatment (acetylcholinesterase inhibitors), short-term immunosuppression (corticosteroids), long-term immunosuppression (azathioprine, cyclosporine, cyclophosphamide, methotrexate, mycophenolate mofetil, rituximab, tacrolimus), rapid acting short-term immunomodulation (intravenous immunoglobulin, plasma exchange), and long-term immunomodulation (thymectomy). This review explores in detail these different treatment options. Potential future treatments are also discussed. PMID:21845054

Robotic radiosurgery vs. brachytherapy as a boost to intensity modulated radiotherapy for tonsillar fossa and soft palate tumors: the clinical and economic impact of an emerging technology.

As a basis for making decisions regarding optimal treatment for patients with tonsillar fossa and soft palate tumors, we conducted a preliminary investigation of costs and quality of life (QoL) for two modalities [brachytherapy (BT) and robotic radiosurgery] used to boost radiation to the primary tumors following external beam radiotherapy. BT was well established in our center; a boost by robotic radiosurgery was begun more recently in patients for whom BT was not technically feasible. Robotic radiosurgery boost treatment has the advantage of being non-invasive and is able to reach tumors in cases where there is deep parapharyngeal tumor extension. A neck dissection was performed for patients with nodal-positive disease. Quality of life (pain and difficulty swallowing) was established in long-term follow-up for patients undergoing BT and over a one-year follow-up in robotic radiosurgery patients. Total hospital costs for both groups were computed. Our results show that efficacy and quality of life at one year are comparable for BT and robotic radiosurgery. Total cost for robotic radiosurgery was found to be less than BT primarily due to the elimination of hospital admission and operating room expenses. Confirmation of robotic radiosurgery treatment efficacy and reduced morbidity in the long term requires further study. Quality of life and cost analyses are critical to Health Technology Assessments (HTA). The present study shows how a preliminary HTA of a new medical technology such as robotic radiosurgery with its typical hypofractionation characteristics might be based on short-term clinical outcomes and assumptions of equivalence.

Chemoradiation therapy (CRT) remains a potentially curative treatment in patients with locally advanced head/neck cancer (LA-HNC). However, survival and other outcomes in older patients with head/neck cancer receiving chemoradiotherapy are not well established. This study was performed to elucidate selected outcomes in this patient population. Retrospective study of LA-HNC patients ≥ 70 years of age who had received 5-fluorouracil-hydoxyurea-based CRT with a minimum of 3 years of follow up after therapy initiation was performed. Pre-treatment patient- and cancer-related characteristics were recorded. Survival data in addition to gastrostomy tube utilization, swallowing function, and hematologic toxicity were captured. Eighty-nine patients treated between 1997 and 2009 were eligible for analysis (median age, 76 years; range, 70-94; male, 61%; ECOG PS, 0-1 43%; stage IVA/B, 71%). 86 were evaluable for survival analysis. 5-year overall and event-free survival were both at 32% with a median follow-up time of 39.2 months. The majority (86.5%) were able to complete all planned treatment cycles. A significant proportion of patients, however, required gastrostomy tube during CRT (62%) and developed aspiration during swallowing evaluation post-treatment (44%). Several patients required hospice (9%) or skilled nursing facility (13%) referrals during treatment. Select older adults with LA-HNC can still experience long-term benefits despite 5-year survival rates lower than those historically reported in younger patients undergoing identical CRT regimens although potentially at higher risk for acute toxicities. Assessment and selection of those who can tolerate more intense combined-modality strategies and their long-term outcomes merit further larger, prospective studies. Copyright © 2013 Elsevier Inc.

To assess the impact of mid-treatment parotid gland shrinkage on long term xerostomia during IMRT for oropharyngeal SCC. All patients treated with IMRT at a single Institution from November 2007 to June 2010 and undergoing weekly CT scans were selected. Parotid glands were contoured retrospectively on the mid treatment CT scan. For each parotid gland, the percent change relative to the planning volume was calculated and combined as weighted average. Patients were considered to be xerostomic if developed GR2+ dry mouth according to CTCAE v3.0. Predictors of the time to xerostomia resolution or downgrade to 1 were investigated at both uni- and multivariate analysis. 85 patients were selected. With a median follow up of 35.8 months (range: 2.4-62.6 months), the actuarial rate of xerostomia is 26.2% (SD: 5.3%) and 15.9% (SD: 5.3%) at 2 and 3 yrs, respectively. At multivariate analysis, mid-treatment shrink along with weighted average mean parotid dose at planning and body mass index are independent predictors of the time to xerostomia resolution. Patients were pooled in 4 groups based on median values of both mid-treatment shrink (cut-off: 19.6%) and mean WA parotid pl-D (cut-off: 35.7 Gy). Patients with a higher than median parotid dose at planning and who showed poor shrinkage at mid treatment are the ones with the outcome significantly worse (3-yr rate of xerostomia ≈ 50%) than the other three subgroups (3-yr rate of xerostomia ≈ 10%). For a given planned dose, patients whose parotids significantly shrink during IMRT are less likely to be long-term supplemental fluids dependent.

Management of erectile dysfunction post-radical prostatectomy

2015-01-01

Radical prostatectomy is a commonly performed procedure for the treatment of localized prostate cancer. One of the long-term complications is erectile dysfunction. There is little consensus on the optimal management; however, it is agreed that treatment must be prompt to prevent fibrosis and increase oxygenation of penile tissue. It is vital that patient expectations are discussed, a realistic time frame of treatment provided, and treatment started as close to the prostatectomy as possible. Current treatment regimens rely on phosphodiesterase 5 inhibitors as a first-line therapy, with vacuum erection devices and intraurethral suppositories of alprostadil as possible treatment combination options. With nonresponders to these therapies, intracavernosal injections are resorted to. As a final measure, patients undergo the highly invasive penile prosthesis implantation. There is no uniform, objective treatment program for erectile dysfunction post-radical prostatectomy. Management plans are based on poorly conducted and often underpowered studies in combination with physician and patient preferences. They involve the aforementioned drugs and treatment methods in different sequences and doses. Prospective treatments include dietary supplements and gene therapy, which have shown promise with there proposed mechanisms of improving erectile function but are yet to be applied successfully in human patients.

Cognitive behavior therapy (CBT) is an effective treatment for social anxiety disorder (SAD), but many patients do not respond sufficiently and a substantial proportion relapse after treatment has ended. Predicting an individual's long-term clinical response therefore remains an important challenge. This study aimed at assessing neural predictors of long-term treatment outcome in participants with SAD 1 year after completion of Internet-delivered CBT (iCBT). Twenty-six participants diagnosed with SAD underwent iCBT including attention bias modification for a total of 13 weeks. Support vector machines (SVMs), a supervised pattern recognition method allowing predictions at the individual level, were trained to separate long-term treatment responders from nonresponders based on blood oxygen level-dependent (BOLD) responses to self-referential criticism. The Clinical Global Impression-Improvement scale was the main instrument to determine treatment response at the 1-year follow-up. Results showed that the proportion of long-term responders was 52% (12/23). From multivariate BOLD responses in the dorsal anterior cingulate cortex (dACC) together with the amygdala, we were able to predict long-term response rate of iCBT with an accuracy of 92% (confidence interval 95% 73.2-97.6). This activation pattern was, however, not predictive of improvement in the continuous Liebowitz Social Anxiety Scale-Self-report version. Follow-up psychophysiological interaction analyses revealed that lower dACC-amygdala coupling was associated with better long-term treatment response. Thus, BOLD response patterns in the fear-expressing dACC-amygdala regions were highly predictive of long-term treatment outcome of iCBT, and the initial coupling between these regions differentiated long-term responders from nonresponders. The SVM-neuroimaging approach could be of particular clinical value as it allows for accurate prediction of treatment outcome at the level of the individual.

Psychiatric comorbidity has been associated with increased health risks and poor long-term treatment outcomes in numerous medical disciplines, but its effect in short-term perioperative settings is incompletely understood. The purpose of this study was to evaluate the influence of a preoperative diagnosis of depressive disorder, anxiety disorder, schizophrenia, or dementia on in-hospital (1) adverse events, (2) blood transfusion, and (3) nonroutine discharge in patients undergoing shoulder arthroplasty. Using the National Hospital Discharge Survey (NHDS) database, we identified 348,824 discharges having undergone partial or total shoulder arthroplasty from 1990 to 2007. Multivariable regression analysis was performed for each of the outcome variables. The prevalence of diagnosed depressive disorder was 4.4%, anxiety disorder, 1.6%; schizophrenia, 0.6%; and dementia, 1.5%. Preoperative psychiatric disorders, with the exception of schizophrenia, were associated with higher rates of adverse events. Depression and schizophrenia were associated with higher perioperative rates of blood transfusion. Any preoperative psychiatric illness was associated with higher rates of nonroutine discharge. Patients with preoperative psychiatric illness undergoing shoulder arthroplasty are at increased risk for perioperative morbidity and posthospitalization care. Preoperative screening of psychiatric illness might help with planning of shoulder arthroplasty. Copyright © 2014 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Mosby, Inc.

In open heart surgery using cardiopulmonary bypass, perfusion of the lower extremities is markedly reduced which may induce critical ischaemia in patients with pre-existing peripheral artery disease. Whether these patients have an increased risk for amputation and should better undergo peripheral revascularization prior to surgery remains unclear. From 1 January 2009 to 31 December 2010, 785 consecutive patients undergoing open heart surgery were retrospectively included. In 443 of these patients, preoperative ankle brachial index (ABI) measurements were available. The cohort was divided into four groups: (i) ABI < 0.5, (ii) ABI 0.5-0.69, (iii) ABI 0.7-0.89 or (iv) ABI ≥ 0.9. Follow-up data of 413 (93.2%) patients were analysed with regard to mortality and amputations. The groups differed significantly in terms of age, cardiac risk factors, performed cardiac surgery and renal function. Postoperative delayed wound healing was significantly associated with lower ABI (25.9, 15.2, 27.0 and 9.6% in Groups I-IV, respectively, P = 0.003), whereas 30-day mortality was not significantly higher in patients with lower ABI (0, 4.3, 8.1 and 3.9%, respectively, P = 0.4). Kaplan-Meier models showed a significantly lower long-term survival over 4 years in patients with reduced ABI (P = 0.001, long-rank test) while amputations occurred rarely with only one minor amputation in Group II (P = 0.023). Patients with reduced ABIs undergoing heart surgery showed more wound-healing disturbances, and higher long-term mortality compared with those with normal ABIs. However, no perioperative ischaemia requiring amputation occurred. Thus, reduced ABIs were not associated with increased peripheral risks in open heart surgery but ABI may be helpful in selecting the site for saphenectomy to potentially avoid delayed healing of related wounds in legs with severely impaired arterial perfusion. © The Author 2015.

Little is currently known about predictors of follow-up outcome of psychological treatment of agoraphobia. In this study, we wished to examine predictors of short- and long-term avoidance after inpatient group interventions for agoraphobia. Ninety-six (68%) of 141 agoraphobic patients (74% women) who had completed treatment in two open and one randomized controlled trial (RCT) were followed up 13 to 21 years after start of treatment. Major depression at pre-treatment predicted less short-term (up to one year after end of treatment) improvement in agoraphobic avoidance. Working and being married/cohabiting at pre-treatment predicted greater long-term (across one-year, two-year, and 13-21 years follow-up) improvement. In contrast, the duration of agoraphobia, amount of Axis I and II co-morbidity, being diagnosed with avoidant, dependent, and obsessive-compulsive personality disorder, and the use of antidepressants and benzodiazepines the month before intake to treatment, were unrelated to short-term as well as long-term outcome. As many as 31.9% of the included patients did not attend long-term follow-up and the power of the study was limited. The long time period between the two and 13-21 year follow-ups is a limitation, in which it is difficult to assess what actually happened. Although all the patients received some form of CBT, there was variability among the treatments. The only short-term predictor identified represented a clinical feature, whereas the long-term predictors represented features of the patients' life situation. The limited power of the study precludes the inference that non-significant predictors are unrelated to follow-up outcome. Copyright © 2015 Elsevier B.V. All rights reserved.

To study the effect of carbon dioxide (CO 2 ) therapy on the nitric oxide (NO) pathway by monitoring plasma asymmetric dimethylarginine (ADMA) concentrations. Forty-seven hypertensive patients who underwent transcutaneous CO 2 therapy were enrolled. Thirty healthy individuals were recruited for the control group. Blood samples were taken one hour before, as well as one hour, 24 hours and 3 weeks after the first CO 2 treatment. Controls did not undergo CO 2 treatment. Plasma ADMA levels were measured by ELISA. ADMA levels decreased significantly one hour after the first CO2 treatment compared to the baseline concentrations (p=0.003). Significantly greater reduction was found among patients in whom angiotensin converting enzyme inhibitors (ACEIs) were administered (p=0.019). The short- and long-term decrease of ADMA levels suggests that CO 2 is not only a vasodilator, but also has a beneficial effect on the NO pathway. ACE inhibition seems to enhance the effect of CO 2 treatment. Copyright© 2017, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.

Mechanical ventilation in abdominal surgery.

PubMed

Futier, E; Godet, T; Millot, A; Constantin, J-M; Jaber, S

2014-01-01

One of the key challenges in perioperative care is to reduce postoperative morbidity and mortality. Patients who develop postoperative morbidity but survive to leave hospital have often reduced functional independence and long-term survival. Mechanical ventilation provides a specific example that may help us to shift thinking from treatment to prevention of postoperative complications. Mechanical ventilation in patients undergoing surgery has long been considered only as a modality to ensure gas exchange while allowing maintenance of anesthesia with delivery of inhaled anesthetics. Evidence is accumulating, however, suggesting an association between intraoperative mechanical ventilation strategy and postoperative pulmonary function and clinical outcome in patients undergoing abdominal surgery. Non-protective ventilator settings, especially high tidal volume (VT) (>10-12mL/kg) and the use of very low level of positive end-expiratory pressure (PEEP) (PEEP<5cmH2O) or no PEEP, may cause alveolar overdistension and repetitive tidal recruitment leading to ventilator-associated lung injury in patients with healthy lungs. Stimulated by previous findings in patients with acute respiratory distress syndrome, the use of lower tidal volume ventilation is becoming increasingly more common in the operating room. However, lowering tidal volume, though important, is only part of the overall multifaceted approach of lung protective mechanical ventilation. In this review, we aimed at providing the most recent and relevant clinical evidence regarding the use of mechanical ventilation in patients undergoing abdominal surgery.

A systematic review and analysis of long-term outcomes in attention deficit hyperactivity disorder: effects of treatment and non-treatment

PubMed Central

2012-01-01

Background In childhood, attention deficit/hyperactivity disorder (ADHD) is characterized by age-inappropriate levels of inattentiveness/disorganization, hyperactivity/impulsiveness, or a combination thereof. Although the criteria for ADHD are well defined, the long-term consequences in adults and children need to be more comprehensively understood and quantified. We conducted a systematic review evaluating the long-term outcomes (defined as 2 years or more) of ADHD with the goal of identifying long-term outcomes and the impact that any treatment (pharmacological, non-pharmacological, or multimodal) has on ADHD long-term outcomes. Methods Studies were identified using predefined search criteria and 12 databases. Studies included were peer-reviewed, primary studies of ADHD long-term outcomes published between January 1980 to December 2010. Inclusion was agreed on by two independent researchers on review of abstracts or full text. Published statistical comparison of outcome results were summarized as poorer than, similar to, or improved versus comparators, and quantified as percentage comparisons of these categories. Results Outcomes from 351 studies were grouped into 9 major categories: academic, antisocial behavior, driving, non-medicinal drug use/addictive behavior, obesity, occupation, services use, self-esteem, and social function outcomes. The following broad trends emerged: (1) without treatment, people with ADHD had poorer long-term outcomes in all categories compared with people without ADHD, and (2) treatment for ADHD improved long-term outcomes compared with untreated ADHD, although not usually to normal levels. Only English-language papers were searched and databases may have omitted relevant studies. Conclusions This systematic review provides a synthesis of studies of ADHD long-term outcomes. Current treatments may reduce the negative impact that untreated ADHD has on life functioning, but does not usually 'normalize' the recipients. PMID:22947230

Models incorporating long-term outcomes (LTOs) are not available to assess the health economic impact of attention-deficit/hyperactivity disorder (ADHD). Develop a conceptual modelling framework capable of assessing long-term economic impact of ADHD therapies. Literature was reviewed; a conceptual structure for the long-term model was outlined with attention to disease characteristics and potential impact of treatment strategies. The proposed model has four layers: i) multi-state short-term framework to differentiate between ADHD treatments; ii) multiple states being merged into three core health states associated with LTOs; iii) series of sub-models in which particular LTOs are depicted; iv) outcomes collected to be either used directly for economic analyses or translated into other relevant measures. This conceptual model provides a framework to assess relationships between short- and long-term outcomes of the disease and its treatment, and to estimate the economic impact of ADHD treatments throughout the course of the disease.

A long-term, implantable, electrically actuated left ventricular assist system (THI/Gould LVAS) is being developed and characterized in vitro and in vivo for utilization in patients with end-stage heart disease. This system consists of five major components: a long-term, implantable blood pump (THI E-type ALVAD); an electrical-mechanical energy converter (Gould Model V); a control unit with batteries; a volume compensation system; and an external power supply and monitoring unit. Two of these components (blood pump and electrical-mechanical energy converter) have been integrated, and are undergoing chronic in vivo evaluations in calves. Thus far, 44 pneumatically and electrically actuated THI/Gould LVAS evaluations have been performed. This experience has resulted in greater than 6.5 years of actuation in vivo, with durations exceeding 1 year. System in vivo performance in terms of durability, mechanical reliability, hemodynamic effectiveness, and biocompatibility has been satisfactory. Demonstration of long-term (2-year) effectiveness in supporting the circulation is the ultimate goal.

Penile fracture is an emergency in urology. Surgical management is recommended, but objective data of postoperative long-term effects, especially regarding voiding and erectile function, vary. To assess long-term results of patients undergoing surgical therapy for penile fracture. Patients presenting with suspicion of penile fracture were included in this study. Diagnosis of penile fracture was made by clinical assessment and surgery performed thereafter. The defect of the tunica albuginea was closed by absorbable suture. In case of concomitant urethral lesion, the defect was repaired simultaneously. Voiding and erectile function were evaluated at long-term follow-up by mail. Patients' status before penile fracture was assessed retroactively. Erectile function was assessed by the International Index of Erectile Function questionnaire and voiding function by the International Prostate Symptom Score questionnaire. N = 34 patients were included. Penile fracture was suspected in 28/34 (82.4%) patients. Twenty-six of the 28 (92.9%) patients underwent surgery. Only less than half of confirmed fracture patients presented with the classical triad of an audible crack, detumescense, and hematoma. Fourteen of the 26 (53.8%) patients after surgery were available for follow-up. Mean follow-up was 45.6 months (range: 3.6-128.4). In 13/14 (92.9%) patients, penile fracture was confirmed by surgery. At follow-up, 7/13 (53.8%) patients had impaired erectile function, with 3/13 (23.1%) patients needing medical treatment. Four of the 13 (30.8%) patients showed deterioration of voiding including occurrence of urethral fistula. Penile fracture is an emergency for which surgery should be offered. Clinical suspicion of fracture should be high even with hematoma alone. Concomitant urethral injury is common, particularly with bilateral corporal rupture and/or initial hematuria. Preoperative counseling should include discussion of long-term erectile and voiding dysfunction, penile deformity, and urethral fistula both with and without surgery. Close patient follow-up is required. © 2013 International Society for Sexual Medicine.

Little is known about the long-term medical status of patients with severe obsessive-compulsive disorder (OCD) undergoing capsulotomy, a neurosurgical last-resort treatment. The present study used national registers to identify all operated patients with OCD in Sweden and evaluated their long-term medical status, including mortality, hospital admissions and psychotropic medication after capsulotomy for OCD. Register-based long-term follow-up cohort study. We used the procedural and diagnostic codes in the Swedish National Patient Register to define the study population between 1970 and March 2013. Verification by manual review of medical records of the indication for surgery in those identified by the register yielded the final study cohort of 70 patients, followed 13-43 years after surgery. The sensitivity of the case selection method was 86%. We studied hospitalisation 5 years before and after surgery. Mortality data were derived from the Causes of Death Register. The Prescribed Drug Register was used to study psychotropic drug utilisation. By March 2013, 29 of the 70 patients were deceased. Their mean age at the time of death was 68 years (SD=14). Two patients had committed suicide and one had died of suspected suicide. Seventy per cent had been admitted to a psychiatric ward in the 5 years preceding surgery, and 84% in the first five postoperative years. Seventy-five per cent of those alive in 2012 were prescribed at least two psychotropic medications, often at high doses, the most common being antidepressants. Malignant OCD has a poor long-term prognosis. Patients who are candidates for surgery should be informed that, while OCD symptoms may be ameliorated with surgery, they should not expect long-term freedom from medication and psychiatric care. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The role of gender on long-term infrainguinal open surgery outcomes still remains uncertain in critical limb ischemia patients. The aim of this study is to evaluate the gender-specific differences in patient characteristics and long-term clinical outcomes in terms of survival, primary patency and limb salvage among patients undergoing infrainguinal open surgery for CLI. All consecutive patients undergoing infrainguinal open surgery for critical limb ischemia between 2003 and 2012 were included. Survival, limb salvage and primary patency rates were assessed. Independent outcome determinants were identified by the Cox proportional hazard ratio using age and gender as adjustment factors. 584 patients (269 women and 315 men, mean age 76 and 71 years respectively) underwent 658 infrainguinal open surgery (313 in women and 345 in men). Survival rate at 6 years was lower among women compared to men with 53.5% vs 70.9% (p < 0.001). The same applied to primary patency (35.9% vs 52.4%, p < 0.001) and limb salvage (54.3% vs 81.1%, p < 0.001) at 6 years. Female-gender was an independent factor predicting death (hazard ratio 1.50), thrombosis (hazard ratio 2.37) and limb loss (hazard ratio 7.05) in age and gender-adjusted analysis. Gender-related disparity in critical limb ischemia open surgical revascularization outcomes still remains. Copyright © 2015 European Society for Vascular Surgery. Published by Elsevier Ltd.

EdU induces DNA damage response and cell death in mESC in culture.

2013-03-01

Recently, a novel DNA replication precursor analogue called 5-ethynyl-2'-deoxyuridine (EdU) has been widely used to monitor DNA synthesis as an alternative to bromodeoxyuridine. Use of EdU benefits from simplicity and reproducibility and the simple chemical detection systems allows excellent preservation of nuclear structure. However, the alkyne moiety is highly reactive, raising the possibility that incorporation might compromise genome stability. To assess the extent of possible DNA damage, we have analysed the effect of EdU incorporation into DNA during short- and long-term cell culture using a variety of cell lines. We show that EdU incorporation has no measurable impact on the rate of elongation of replication forks during synthesis. However, using different cell lines we find that during long-term cell culture variable responses to EdU incorporation are seen, which range from delayed cell cycle progression to complete cell cycle arrest. The most profound phenotypes were seen in mouse embryonic stem cells, which following incorporation of EdU accumulated in the G2/M-phase of the cell cycle before undergoing apoptosis. In long-term cell culture, EdU incorporation also triggered a DNA damage response in all cell types analysed. Our study shows that while EdU is extremely useful to tag sites of on-going replication, for long-term studies (i.e. beyond the cell cycle in which labelling is performed), a careful analysis of cell cycle perturbations must be performed in order to ensure that any conclusions made after EdU treatment are not a direct consequence of EdU-dependent activation of cell stress responses.

This study examined the long-term outcomes of women who were pregnant or parenting at admission to women-only (WO; n=500) versus mixed-gender (MG; a matched sample of 500) substance abuse treatment programs. Administrative records on arrests, incarcerations, mental health services utilization, and drug treatment participation were collected, covering 3 years pre-admission and 8 years post-admission. Women treated in WO programs had lower levels of arrest, mental health services utilization rates, and drug treatment participation during the first year after drug treatment. No differences were found between the two groups in the long-term trajectories except that WO program participants had lower incarceration rates during the third year after treatment. The study findings suggest a positive short-term impact of WO versus MG programs with regard to arrest and mental health service utilization. Limited long-term gain is shown in the reductions in post-treatment incarceration. The study findings suggest the added value of specialized WO programs and begin to address the gap in knowledge regarding long-term outcomes for substance-abusing women. PMID:21466942

Children undergoing cancer treatment describe their experiences of comfort in interviews and drawings.

Children with cancer often undergo a long course of treatment, described as painful, and associated with feelings of discomfort and need of comfort. The aim of this descriptive interview study was to investigate how children, aged 3 to 9 years, undergoing cancer treatment describe their experience of comfort. The children were interviewed and asked to make drawings. Data were content analyzed and four themes were constructed--enduring discomfort, expressing discomfort, finding comfort, and comforting others. The findings show that the children endured discomfort during treatment, and were sometimes able to express it. They found comfort especially from their family and from hospital staff. The children also described that they comforted family members. The findings are in accordance with previous research about children's and adults' accounts of comfort. An incidental finding is that parents were surprised when they listened to the children's accounts of their experience of discomfort and comfort and achieved a better understanding of their children.

Long-term academic stress enhances early processing of facial expressions.

Exposure to long-term stress can lead to a variety of emotional and behavioral problems. Although widely investigated, the neural basis of how long-term stress impacts emotional processing in humans remains largely elusive. Using event-related brain potentials (ERPs), we investigated the effects of long-term stress on the neural dynamics of emotionally facial expression processing. Thirty-nine male college students undergoing preparation for a major examination and twenty-one matched controls performed a gender discrimination task for faces displaying angry, happy, and neutral expressions. The results of the Perceived Stress Scale showed that participants in the stress group perceived higher levels of long-term stress relative to the control group. ERP analyses revealed differential effects of long-term stress on two early stages of facial expression processing: 1) long-term stress generally augmented posterior P1 amplitudes to facial stimuli irrespective of expression valence, suggesting that stress can increase sensitization to visual inputs in general, and 2) long-term stress selectively augmented fronto-central P2 amplitudes for angry but not for neutral or positive facial expressions, suggesting that stress may lead to increased attentional prioritization to processing negative emotional stimuli. Together, our findings suggest that long-term stress has profound impacts on the early stages of facial expression processing, with an increase at the very early stage of general information inputs and a subsequent attentional bias toward processing emotionally negative stimuli.

Long, Kevin C; Menon, Raman; Bastawrous, Amir; Billingham, Richard

2016-03-01

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology. Patients with lesions should undergo history and physical exam including digital rectal exam and standard anoscopy. High-resolution anoscopy can be considered as well, although it is of questionable time and cost-effectiveness. Nonoperative treatments include expectant surveillance and topical imiquimod or 5-fluorouracil. Operative therapies include wide local excision and targeted ablation with electrocautery, infrared coagulation, or cryotherapy. Recurrence rates remain high regardless of treatment delivered and surveillance is paramount, although optimal surveillance regimens have yet to be established.

Diplomatic Assistance: Can Helminth-Modulated Macrophages Act as Treatment for Inflammatory Disease?

PubMed Central

Steinfelder, Svenja; O’Regan, Noëlle Louise; Hartmann, Susanne

2016-01-01

Helminths have evolved numerous pathways to prevent their expulsion or elimination from the host to ensure long-term survival. During infection, they target numerous host cells, including macrophages, to induce an alternatively activated phenotype, which aids elimination of infection, tissue repair, and wound healing. Multiple animal-based studies have demonstrated a significant reduction or complete reversal of disease by helminth infection, treatment with helminth products, or helminth-modulated macrophages in models of allergy, autoimmunity, and sepsis. Experimental studies of macrophage and helminth therapies are being translated into clinical benefits for patients undergoing transplantation and those with multiple sclerosis. Thus, helminths or helminth-modulated macrophages present great possibilities as therapeutic applications for inflammatory diseases in humans. Macrophage-based helminth therapies and the underlying mechanisms of their therapeutic or curative effects represent an under-researched area with the potential to open new avenues of treatment. This review explores the application of helminth-modulated macrophages as a new therapy for inflammatory diseases. PMID:27101372

To present the profile of patients undergoing surgical treatment for vertigo at a contemporary institutional vertigo clinic. A retrospective analysis of clinical charts. The charts of 1060 patients, referred to an institutional vertigo clinic from January 2003 to December 2012, were studied. The clinical profile and long-term outcomes of patients who underwent surgery were analysed. Of 1060 patients, 12 (1.13 per cent) were managed surgically. Of these, disease-modifying surgical procedures included perilymphatic fistula repair (n = 7) and microvascular decompression of the vestibular nerve (n = 1). Labyrinth destructive procedures included transmastoid labyrinthectomy (n = 2) and labyrinthectomy with vestibular nerve section (n = 1). One patient with vestibular schwannoma underwent both a disease-modifying and destructive procedure (translabyrinthine excision). All patients achieved excellent vertigo control, classified as per the American Academy of Otolaryngology - Head and Neck Surgery 1995 criteria. With the advent of intratympanic treatments, surgical treatments for vertigo have become further limited. However, surgery with directed intent, in select patients, can give excellent results.

Introduction Psychological distress is common in end-stage kidney disease (ESKD) and is associated with poorer health outcomes. Cognitive behavioural therapy (CBT) is recommended in UK clinical guidelines for the management of depression in people with long-term conditions. Access to skilled therapists competent in managing the competing mental and physical health demands of ESKD is limited. Online CBT treatments tailored to the needs of the ESKD population offers a pragmatic solution for under-resourced services. This study examines the feasibility and acceptability of implementing a two-arm parallel randomised controlled trial of online CBT with (intervention arm) and without (control arm) therapist support to improve psychological distress in patients undergoing haemodialysis. Methods Patients will be screened for depression and anxiety while attending for their haemodialysis treatments. We aim to recruit 60 adult patients undergoing haemodialysis who meet criteria for mild to moderately severe symptoms of depression and/or anxiety. Patients will be randomised individually (using a 1:1 computerised sequence ratio) to either online CBT with therapist telephone support (intervention arm), or online CBT with no therapist (control arm). Outcomes include feasibility and acceptability descriptive data on rates of recruitment, randomisation, retention and treatment adherence. Self-report outcomes include measures of depression (Patient Health Questionnaire-9), anxiety (Generalised Anxiety Disorder-7), quality of life (Euro-QoL), service use (client service receipt inventory) and illness cognitions (brief illness perception questionnaire). A qualitative process evaluation will also be conducted. The statistician will be blinded to treatment allocation. Ethics and dissemination A National Health Service (NHS) research ethics committee approved the study. Data from this study will provide essential information for the design and testing of further interventions to ameliorate distress in patients undergoing dialysis. Any amendments to the protocol will be submitted to the NHS committee and study sponsor. Trial registration number NCT023528702; Pre-results. PMID:27072573

2017-02-01

To describe a novel surgical technique for the correction of recurrent obstructive urolithiasis in male goats. Clinical case series. Castrated male goats (n = 4). Medical records of male goats having undergone vesicopreputial anastomosis (VPA) as a treatment for obstructive urolithiasis were reviewed for history, signalment, clinical signs, and intraoperative and postoperative complications. Long-term follow-up (≥12 months) was obtained by telephone interview with owners or by clinical examination. All goats had undergone at least one surgical procedure (median, 2.5, range 2-4) to correct obstructive urolithiasis before undergoing VPA. Postoperative complications included premature removal of the tube from the bladder (1 goat), bacterial cystitis (2), and abscess formation (1). One goat suffered stricture of the anastomosis site 3 months following the original procedure and underwent a second VPA and 1 goat died 7 months after surgery due to severe, acute hydronephrosis and renal failure. Long-term survival ≥12 months was good with 3/4 goats (75%) or 3/5 VPA procedures (60%) having unobstructed urine flow at 12 months. Vesicopreputial anastomosis is a feasible surgical procedure for the correction of recurrent obstructive urolithiasis in male goats and one that can result in a favorable clinical outcome. Further investigation in a larger population of goats is warranted for the evaluation of the suitability of VPA in male goats with obstructive urolithiasis. © 2017 The American College of Veterinary Surgeons.

Case Report: 35-Year Follow-up for Nonvascularized Toe Phalangeal Transfer for Multiple Digit Symbrachydactyly.

Naran, Sanjay; Imbriglia, Joseph E

2016-12-01

Background: A case is discussed in which a young girl was born with symbrachydactyly of multiple digits in whom nonvascularized proximal toe phalanges were transferred to the aphalangic digits at the age of four. At 39 years of age, she presented incidentally to our clinic and was observed to have a very functional hand with mobile metacarpophalangeal joints in all reconstructed digits. Methods: We present a case report which is discussed in the context of long-term follow-up, and phalangeal growth in the absence of distraction, and a review of the current literature in regards to outcomes for this modality of treatment. Results: We document growth of the transplanted phalanges, despite surgery occurring after the reported optimum age of before 18 months, and the patient not undergoing distraction. The patient reported no donor site morbidity in regards to function or psychosocial impact. Furthermore, we observed active function at the metacarpophalangeal joints of all operated digits. Conclusions: We report the longest follow-up (35 years) following nonvascularized proximal toe phalangeal transfer for short finger type symbrachydactyly. We highlight the long-term functional outcome of nonvascularized toe phalangeal transfers, and present an overview of the current outcome literature for this type of procedure, advocating that nonvascularized toe phalangeal transfers remain a viable treatment option for select cases of symbrachydactyly.

Urogenital tuberculosis (TB) is common in developing countries. We present our experience of surgically managed cases of genitourinary TB (GUTB). We retrospectively reviewed 60 cases GUTB who underwent surgery at our center from January 2003 to January 2010. Mode of presentation, organ involvement, investigation, surgical treatment and follow-up were studied. There were 38 males and 22 females with a mean age of 32.5 years. The most common symptom was irritative voiding symptoms. The most common organ involved was bladder in 33 cases, and next most common was kidney in 30 cases. Preoperative bacteriologic diagnosis was confirmed in only 19 cases. A total of 66 procedures were performed as some patients needed more than one procedure. These included 35 ablative procedures and 31 reconstructive procedures. All the patients were followed-up with renal function test (RFT) at 3, 6 and 12 months. The intravenous urography and diethylenetriamine pentaacetic acid scan were performed at 3 months when indicated. Then the patients were followed with RFT and ultrasonography 6 monthly for 3 years and then annual RFT. Many patients of urogenital TB present late with cicatrisation sequelae. Multidrug chemotherapy with judicious surgery as and when indicated is the ideal treatment. The results of reconstructive surgery are good and should be done when possible. Rigorous and long term follow-up is necessary in patients undergoing reconstructive surgery.

Purpose: The objective of this cross-sectional study was to characterize long-term breast pain in patients undergoing breast-conserving surgery and radiation (BCT) and to identify predictors of this pain. Methods and Materials: We identified 355 eligible patients with Tis-T2N0M0 breast cancer who underwent BCT in 2007 to 2011, without recurrent disease. A questionnaire derived from the Late Effects Normal Tissue Task Force (LENT) Subjective, Objective, Management, Analytic (SOMA) scale was mailed with 7 items detailing the severity, frequency, duration, and impact of ipsilateral breast pain over the previous 2 weeks. A logistic regression model identified predictors of long-term breast pain based on questionnaire responsesmore » and patient, disease, and treatment characteristics. Results: The questionnaire response rate was 80% (n=285). One hundred thirty-five patients (47%) reported pain in the treated breast, with 19 (14%) having pain constantly or at least daily; 15 (11%) had intense pain. The pain interfered with daily activities in 11 patients (8%). Six patients (4%) took analgesics for breast pain. Fourteen (10%) thought that the pain affected their quality of life. On univariable analysis, volume of breast tissue treated to ≥105% of the prescribed dose (odds ratio [OR] 1.001 per cc, 95% confidence interval [CI] 1.000-1.002; P=.045), volume treated to ≥110% (OR 1.009 per cc, 95% CI 1.002-1.016; P=.012), hormone therapy use (OR 1.95, 95% CI 1.12-3.39; P=.02), and other sites of pain (OR 1.79, 95% CI 1.05-3.07; P=.03) predicted for long-term breast pain. On multivariable analysis, volume ≥110% (OR 1.01 per cc, 95% CI 1.003-1.017; P=.007), shorter time since treatment (OR 0.98 per month, 95% CI 0.96-0.998; P=.03), and hormone therapy (OR 1.84, 95% CI 1.05-3.25; P=.03) were independent predictors of pain. Conclusion: Long-term breast pain was common after BCT. Although nearly half of patients had pain, most considered it tolerable. Dosimetric inhomogeneity independently predicted for pain and should be minimized to the greatest extent possible.« less

To evaluate long-term function of vascular access ports (VAPs) implanted in the femoral vein of dogs and cats undergoing cancer treatment. Prospective clinical study. 3 dogs and 6 cats treated via chemotherapy or radiation. VAPs were surgically implanted in the left femoral vein of 3 dogs and 6 cats over a 1-year period. Injection port location was alternated to either a caudal thoracic or ilial location in each patient. Duration of VAP function, ease of infusion, and ease of aspiration through the VAPs were recorded, and associated complications were assessed at each VAP use. Client satisfaction with VAP placement was evaluated by use of a questionnaire. Primary uses of the VAPs included blood sampling and delivering sedative or chemotherapeutic drugs. Median duration of successful infusion was 147 days (range, 60 to 370 days), and median duration of successful aspiration was 117 days (range, 10 to 271 days). The frequency of signs of VAP-related discomfort was low (7% of patient observations). Clients were satisfied with their decision to use VAPs. Complications included partial (n = 7) or complete (2) VAP occlusion, port migration (1), and presumptive infection (1). Results suggested that VAP implantation into the femoral vein provides an acceptable means of chronic venous access in dogs and cats undergoing cancer treatment.

There is controversy in the literature about the choice of expectant medical treatment versus surgical treatment of hiatal hernias, depending on the presence or absence of symptoms. This study presents the results obtained by our group, considering disease duration and postoperative results. A total of 121 patients were included and divided by age, disease duration, type of hiatal hernia and postoperative outcome. In 32% of the patients younger than 70 years, symptom duration was longer than 11 years and 68% of those aged more than 71 years had long-term symptoms (p<.05). Type iv hernias (complex) and those with diameters measuring more than 16 cm were observed in the group with longer symptom duration. Complications were more frequent in the older age group, in those with longer symptom duration and in those with type iv complex hernias. There was no postoperative mortality and only one patient (0.8%) with a type iii hernia and severe oesophagitis required reoperation. We recommend that patients with hiatal hernia undergo surgery at diagnosis to avoid complications and risks. Older patients should not be excluded from surgical indication but should undergo a complete multidisciplinary evaluation to avoid complications and postoperative mortality. Copyright © 2012 AEC.

Objective The purpose of this retrospective study was to investigate short-term and long-term skeletodental outcomes of Class III activator treatment. Methods A Class III activator treatment group (AG) comprised of 22 patients (9 boys, 13 girls) was compared with a Class III control group (CG) comprised of 17 patients (6 boys, 11 girls). The total treatment period was divided into three stages; the initial stage (T1), the post-activator treatment or post-mandibular growth peak stage (T2), and the long-term follow-up stage (T3). Cephalometric changes were evaluated statistically via the Mann-Whitney U-test and the Friedman test. Results The AG exhibited significant increases in the SNA angle, ANB angle, Wits appraisal, A point-N perpendicular, Convexity of A point, and proclination of the maxillary incisors, from T1 to T2. In the long-term follow-up (T1-T3), the AG exhibited significantly greater increases in the ANB angle, Wits appraisal, and Convexity of A point than the CG. Conclusions Favorable skeletal outcomes induced during the Class III activator treatment period were generally maintained until the long-term follow-up period of the post-mandibular growth peak stage.

Determinants to trigger memory reconsolidation: The role of retrieval and updating information.

PubMed

Rodriguez-Ortiz, Carlos J; Bermúdez-Rattoni, Federico

2017-07-01

Long-term memories can undergo destabilization/restabilization processes, collectively called reconsolidation. However, the parameters that trigger memory reconsolidation are poorly understood and are a matter of intense investigation. Particularly, memory retrieval is widely held as requisite to initiate reconsolidation. This assumption makes sense since only relevant cues will induce reconsolidation of a specific memory. However, recent studies show that pharmacological inhibition of retrieval does not avoid memory from undergoing reconsolidation, indicating that memory reconsolidation occurs through a process that can be dissociated from retrieval. We propose that retrieval is not a unitary process but has two dissociable components; one leading to the expression of memory and the other to reconsolidation, referred herein as executer and integrator respectively. The executer would lead to the behavioral expression of the memory. This component would be the one disrupted on the studies that show reconsolidation independence from retrieval. The integrator would deal with reconsolidation. This component of retrieval would lead to long-term memory destabilization when specific conditions are met. We think that an important number of reports are consistent with the hypothesis that reconsolidation is only initiated when updating information is acquired. We suggest that the integrator would initiate reconsolidation to integrate updating information into long-term memory. Copyright © 2016 Elsevier Inc. All rights reserved.

Robust T cell function recovery has been shown to be crucial in determining allogeneic hematopoietic stem cell transplantation (HSCT) outcome, and there is growing evidence that the thymus plays a central role in regulating this process. We performed a long-term analysis of the role of thymic activity recovery in a population of pediatric patients undergoing allogeneic HSCT by signal joint T cell receptor excision circle (sjTREC) quantification. In this study, characterized by a long-term follow-up (median, 72 months), we found patients with higher levels of sjTRECs before transplantation had a statistically significant reduced risk of death compared with patients with lower values (relative risk, .31; 95% confidence interval, .30 to .32; P = .02), showing this different outcome was mainly related to a reduction of relapse incidence (14% versus 43%, P = .02). Unlike previous reports, we observed no correlation between sjTREC levels and lymphocyte recovery. Moreover, we confirmed that only graft-versus-host disease influenced thymic activity after transplantation. In conclusion, our results suggest an association between pretransplantation thymic activity and the long-term outcome of pediatric patients undergoing HSCT, mainly through a reduction of relapse opportunities.

Childhood cancer and its treatment have considerable impact on a child's physical and mental wellbeing. Especially long-term administration of chemotherapy and/or radiotherapy impairs physical fitness both during and after therapy, when children often present with muscle weakness and/or low cardiorespiratory fitness. Physical exercise can improve these two elements of physical fitness, but the positive effects of physical exercise might be further increased when a child's wellbeing is simultaneously enhanced by psychosocial training. Feeling better may increase the willingness and motivation to engage in sports activities. Therefore, this multi-centre study evaluates the short and long-term changes in physical fitness of a child with a childhood malignancy, using a combined physical exercise and psychosocial intervention program, implemented during or shortly after treatment. Also examined is whether positive effects on physical fitness reduce inactivity-related adverse health problems, improve quality of life, and are cost-effective. This multi-centre randomized controlled trial compares a combined physical and psychosocial intervention program for children with cancer, with care as usual (controls). Children with cancer (aged 8-18 years) treated with chemotherapy and/or radiotherapy, and who are no longer than 1 year post-treatment, are eligible for participation. A total of 100 children are being recruited from the paediatric oncology/haematology departments of three Dutch university medical centres. Patients are stratified according to pubertal stage (girls: age ≤10 or >10 years; boys: ≤11 or >11 years), type of malignancy (haematological or solid tumour), and moment of inclusion into the study (during or after treatment), and are randomly assigned to the intervention or control group. Childhood cancer patients undergoing long-term cancer therapy may benefit from a combined physical exercise and psychosocial intervention program since it may maintain or enhance their physical fitness and increase their quality of life. However, the feasibility, patient need, and effectiveness of such a program should be established before the program can be implemented as part of standard care.

SOM Stability under Long-term Recovery from Acidic Deposition in a Northern Hardwood Forest

Forested ecosystems in the Northeast U.S.A. are currently recovering from decades of acidic deposition that decreased soil pH, leached base cations, and increased soluble aluminum (Al) in soils. Because most research examining SOM dynamics in these ecosystems has taken place against a background of acidic deposition, it remains poorly understood how SOM pools will change as a result of the long-term trajectory of recovery from acidic deposition throughout the region. These potential changes may alter soil fertility status as well as the chemistry of receiving freshwater bodies. Watershed-scale experiments that increase soil pH and base cation status may provide insight into how SOM pools in these recovering ecosystems will respond on timescales of decades to centuries, but results from these experiments have been equivocal. At Hubbard Brook Experimental Forest in New Hampshire, a watershed-scale acid remediation treatment of calcium silicate caused a 40% decline of SOM pools in the humic (Oa) soil horizon, in addition to increasing soil pH and base saturation. We sought to understand the mechanisms driving this substantial loss of SOM. We found that, in the Oa horizon of the treatment watershed, respiration and nitrogen (N) mineralization were significantly, positively correlated with exchangeable calcium (Ca) and uncorrelated with soil pH; in a linear regression, exchangeable Ca explained 76% of the variation in respiration and 74% of the variation in nitrogen mineralization in the treatment soils. These metrics were uncorrelated in soils from a nearby reference watershed, where Ca is uniformly low. This suggests that the rate and magnitude of soil Ca changes during recovery from acid deposition may provide an important long-term control on the stability of SOM in these ecosystems. Additionally, we found substantially enhanced in-stream biotic uptake of the inorganic N released from this enhanced SOM decomposition, with growing-season N flux from the treatment watershed attenuated by 15-55% due to in-stream uptake. This suggests that receiving headwaters undergoing recovery from acid deposition have the capacity to mitigate enhanced nutrient efflux due to increased SOM decomposition.

Overweight, but not obesity, paradox on mortality following coronary artery bypass grafting.

To determine whether an "obesity paradox" on post-coronary artery bypass grafting (CABG) mortality exists, we abstracted exclusively adjusted odds ratios (ORs) and/or hazard ratios (HRs) for mortality from each study, and then combined them in a meta-analysis. MEDLINE and EMBASE were searched through April 2015 using PubMed and OVID, to identify comparative studies, of overweight or obese versus normal weight patients undergoing CABG, reporting adjusted relative risk estimates for short-term (30-day or in-hospital) and/or mid-to-long-term all-cause mortality. Our search identified 14 eligible studies. In total our meta-analysis included data on 79,140 patients undergoing CABG. Pooled analyses in short-term mortality demonstrated that overweight was associated with a statistically significant 15% reduction relative to normal weight (OR, 0.85; 95% confidence interval [CI], 0.74-0.98; p=0.03) and no statistically significant differences between mild obesity, moderate/severe obesity, or overall obesity and normal weight. Pooled analyses in mid-to-long-term mortality demonstrated that overweight was associated with a statistically significant 10% reduction relative to normal weight (HR, 0.90; 95% CI, 0.84 to 0.96; p=0.001); and no statistically significant differences between mild obesity, moderate/severe obesity, or overall obesity and normal weight. Overweight, but not obesity, may be associated with better short-term and mid-to-long-term post-CABG survival relative to normal weight. An overweight, but not obesity, paradox on post-CABG mortality appears to exist. Copyright © 2015 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

BACKGROUND Conventional ovarian stimulation and the transfer of two embryos in IVF exhibits an inherent high probability of multiple pregnancies, resulting in high costs. We evaluated the cost-effectiveness of a mild compared with a conventional strategy for IVF. METHODS Four hundred and four patients were randomly assigned to undergo either mild ovarian stimulation/GnRH antagonist co-treatment combined with single embryo transfer, or standard stimulation/GnRH agonist long protocol and the transfer of two embryos. The main outcome measures are total costs of treatment within a 12 months period after randomization, and the relationship between total costs and proportion of cumulative pregnancies resulting in term live birth within 1 year of randomization. RESULTS Despite a significantly increased average number of IVF cycles (2.3 versus 1.7; P < 0.001), lower average total costs over a 12-month period (8333 versus euro10 745; P = 0.006) were observed using the mild strategy. This was mainly due to higher costs of the obstetric and post-natal period for the standard strategy, related to multiple pregnancies. The costs per pregnancy leading to term live birth were euro19 156 in the mild strategy and euro24 038 in the standard. The incremental cost-effectiveness ratio of the standard strategy compared with the mild strategy was euro185 000 per extra pregnancy leading to term live birth. CONCLUSIONS Despite an increased mean number of IVF cycles within 1 year, from an economic perspective, the mild treatment strategy is more advantageous per term live birth. It is unlikely, over a wide range of society's willingness-to-pay, that the standard treatment strategy is cost-effective, compared with the mild strategy.

Aortoduodenal fistula in a patient on intravitreal bevacizumab injections: a case report.

2015-01-01

An 88-year-old woman on long-term intravitreal bevacizumab presented with acute gastrointestinal hemorrhage. She was stabilized and underwent nonrevealing upper endoscopy. She continued to require intermittent blood transfusions, and resulting computed tomography of the abdomen revealed an aortoduodenal fistula. The patient was undergoing treatment for her macular degeneration with intravitreal bevacizumab, an angiogenesis inhibitor frequently used to treat solid organ malignancies. Systemic administration has been associated with serious adverse events, including gastrointestinal hemorrhage, perforation, and fistula formation. Intravitreal bevacizumab has been used off-label to treat macular degeneration, but data on the safety of this therapy are limited. Given her lack of other risk factors, the authors postulate a potential association between intravitreal bevacizumab and aortoduodenal fistula formation in this patient.

Suture and staple-based endoluminal devices for gastroesophageal reflux disease (GERD) and obesity have failed to demonstrate long-term efficacy. To demonstrate the feasibility of mucosal excision and full-thickness suture apposition of the excision beds to create sufficient scar tissue formation at the gastroesophageal junction for the intraluminal treatment of GERD or obesity. Survival animal experiments. Seven mongrel dogs. Interventions. Under general endotracheal anesthesia, a Barostat test was performed on 4 dogs. A mucosal excision device was introduced through the esophagus into the proximal stomach. Two to 4 mucosal excisions were performed on all dogs at or just below the gastroesophageal junction and the mucosal pieces were removed. After hemostasis, an intraluminal suturing instrument was introduced and either 2 or 4 sutures were placed through the excision beds to bring them into apposition. These were tied and the suture strands cut. All dogs were survived for 2 months. End-term endoscopies were performed, and a repeat Barostat procedure was performed on the animals undergoing an antireflux procedure. After euthanasia the stomachs were explanted, examined, photographed, and sectioned for histologic examination. All dogs survived without complication. In the 4 GERD dogs, the Barostat studies demonstrated a significant decrease in gastroesophageal junction compliance. In the 3 dogs undergoing the obesity procedure, the gastric outlet apposition to a 6-mm endoscope was satisfactory with full insufflation and the desired scarring was seen on histologic examination. It is possible to create adequate gastroesophageal junction scarring for the treatment of GERD and obesity. A clinical pilot study will be initiated.

This study investigated the 30-day and long-term prognostic outcomes in patients with ST-segment elevation myocardial infarction (STEMI) complicated with profound cardiogenic shock (CS) undergoing early routine extracorporeal membrane oxygenator (ECMO)-assisted primary percutaneous coronary intervention (PCI). Between December 2005 and December 2014, 65 consecutive STEMI patients with profound CS underwent routine ECMO-supported primary PCI. The incidences of acute pulmonary edema, respiratory failure with requirement of mechanical ventilatory support upon presentation, and 30-day mortality rate were 100%, 95.4%, and 43.1%, respectively. The duration of hospitalization, mean long-term follow-up, and survival rate were 32.1±53.1 (days), 733.6±986.7 (days), and 32.3%, respectively. The mean APACHE score (32.6±8.3 vs. 28.5±7.5), peak serum creatinine level (4.3±2.4 vs. 1.7±1.2mg/dL), incidences of failed ECMO weaning (57.1% vs. 0%), successful ECMO weaning but in-hospital death (40.0% vs. 0%) were significantly lower in 30-day survivors than those in non-survivors (all p<0.05), whereas final thrombolysis in myocardial infarction (TIMI)-3 flow [53.6% vs. 91.9%] showed an opposite pattern compared to that of APACHE score in the two groups (p<0.02). Multivariate analysis demonstrated that unsuccessful reperfusion, failed ECMO weaning, and peak creatinine level were independent predictors of 30-day mortality (all p<0.01). Early ECMO-supported primary PCI in STEMI patients with profound CS was feasible as a life-saving strategy with acceptable 30-day and long-term prognostic outcomes.

Moderate (body mass index [BMI] ≥30) and morbid obesity (BMI ≥35) is increasing at an alarming rate in vascular surgery patients. The objective of this study was to determine the impact of obesity on perioperative and long-term clinical outcomes following open abdominal aortic aneurysm (AAA) repair or endovascular aneurysm repair (EVAR). This review includes patients that underwent open AAA repair (n = 403) or EVAR (n = 223) from 1999 to 2009. Specific patient characteristics such as comorbid diseases, medications, and body mass index (BMI) were assessed. Specific perioperative outcomes such as length of stay, myocardial infarctions, and mortality were reviewed. In addition, long-term outcomes such as rates of reintervention, permanent renal dysfunction, and mortality beyond 30 days were also assessed. The incidence of obesity in open AAA patients was 25.3% (documented incidence 1.5%) and for EVAR was 24.6% (documented incidence 4%). Moderate and morbid obesity was associated with longer intensive care unit (ICU) admissions for both open AAA or EVAR patients (P < .05). However, no significant differences in perioperative outcomes in terms of overall length of stay, myocardial infarction, acute renal failure, wound infections, or mortality were noted between obese and nonobese patients underoing open AAA repair or EVAR (P > .05). Similarly, moderate and morbid obesity was not associated with significant differences in rates of reintervention, permanent renal dysfunction, and mortality beyond 30 days for patients undergoing open AAA repair or EVAR (P > .05). The results of this study indicate that moderate and morbid obesity are not independently associated with adverse perioperative and long-term clinical outcomes for patients undergoing open AAA repair or EVAR. Therefore, either open AAA repair or EVAR can be accomplished safely in moderately obese and morbidly obese patients.

To evaluate the long-term outcomes of treatment of total exudative retinal detachments (ERDs) secondary to Coats disease (stage 3B) and the role of vitrectomy. Retrospective, observational case series. A total of 16 eyes in 16 patients undergoing treatment for total ERDs secondary to Coats disease with at least 5 years of follow-up. We reviewed the records of patients with stage 3B Coats disease. The interventions, including the timing of vitrectomy if used, and clinical course were recorded. The primary outcome measures were visual acuity at the most recent appointment, whether there was progression to neovascular glaucoma (NVG) or phthisis bulbi, and need for enucleation. All patients received ablative treatment (photocoagulation or cryotherapy), with 8 having scleral buckling (SB) and 6 having external drainage of subretinal fluid (XD). Of the 12 patients who had pars plana vitrectomy (PPV), 8 had early PPV (EV) in the first year after presenting, and 4 of 8 in the expectant management group had late PPV (late vitrectomy) at a mean of 4.3 years post-presentation for treatment of significant traction retinal detachment (TRD). The other 4 patients of 8 in the expectant management group did not require vitrectomy. Mean follow-up overall was 9 1/2 years. At the date of last follow-up, 50% had no light perception or light perception vision, which was consistent across the subgroups that underwent EV (4/8), late vitrectomy (2/4), or no PPV (2/4). A total of 4 of 16 patients had progression to NVG or phthisis, 1 of whom required enucleation. In this retrospective series of patients with Stage 3B Coats disease, ablative therapy with a combination of PPV, XD, or SB was effective in preventing progression to NVG or phthisis in the majority of patients, thus preserving the globe. Half of the patients (4/8) in this series who did not undergo PPV in the early vitrectomy group developed late-onset TRD, suggesting a possible role for early prophylactic vitrectomy with possible SB and XD; however, this is balanced by the other half (4/8) in the expectant management group who did not require any vitrectomy.

Background Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty. Although research suggests that Continuous Passive Motion (CPM) should be implemented in the first rehabilitation phase after surgery, there is substantial debate about the duration of each session and the total period of CPM application. A Cochrane review on this topic concluded that short-term use of CPM leads to greater short-term range of motion. It also suggested, however, that future research should concentrate on the treatment period during which CPM should be administered. Methods In a randomised controlled trial we investigated the effectiveness of prolonged CPM use in the home situation as an adjunct to standardised PT. Efficacy was assessed in terms of faster improvements in range of motion (RoM) and functional recovery, measured at the end of the active treatment period, 17 days after surgery. Sixty patients with knee osteoarthritis undergoing TKA and experiencing early postoperative flexion impairment were randomised over two treatment groups. The experimental group received CPM + PT for 17 consecutive days after surgery, whereas the usual care group received the same treatment during the in-hospital phase (i.e. about four days), followed by PT alone (usual care) in the first two weeks after hospital discharge. From 18 days to three months after surgery, both groups received standardised PT. The primary focus of rehabilitation was functional recovery (e.g. ambulation) and regaining RoM in the knee. Results Prolonged use of CPM slightly improved short-term RoM in patients with limited RoM at the time of discharge after total knee arthroplasty when added to a semi-standard PT programme. Assessment at 6 weeks and three months after surgery found no long-term effects of this intervention Neither did we detect functional benefits of the improved RoM at any of the outcome assessments. Conclusion Although results indicate that prolonged CPM use might have a small short-term effect on RoM, routine use of prolonged CPM in patients with limited RoM at hospital discharge should be reconsidered, since neither long-term effects nor transfer to better functional performance was detected.

2015-03-01

The risk of long-term alopecia after pulsed-dye laser (PDL) therapy is unknown. To identify how many practitioners treat hair-bearing sites with PDL and how commonly long-term alopecia occurs, the authors queried pediatric dermatologists about their experiences using this modality. A survey was designed to evaluate the frequency of and factors contributing to long-term alopecia after PDL treatment of port-wine stains (PWS). "Long-term" was defined as no sign of hair regrowth after several years of nontreatment. The survey was administered to attendees at the 2014 Society for Pediatric Dermatology biannual meeting. Sixty-four pediatric dermatologists completed the survey, 50 of whom had experience using PDL. Of these physicians, 86% have used PDL to treat PWS of the eyebrow and 80% have treated PWS of the scalp. Over one-quarter of respondents (25.5%) using PDL on hair-bearing areas had at least 1 of their patients develop long-term alopecia after PDL treatment. The incidence of long-term alopecia after PDL treatment in the surveyed population was 1.5% to 2.6%. The occurrence of long-term alopecia at hair-bearing sites after treatment with PDL may be greater than previously thought. Because the majority of physicians using PDL treat hair-bearing areas, prospective studies are needed to more accurately determine the risk of long-term alopecia and the factors that contribute to it.

To present the long-term surgical outcome of the bony mastoid and epitympanic obliteration technique with canal wall reconstruction (CWR-BOT) in adults with an unstable cavity after previous canal wall-down surgery for extensive cholesteatoma. Retrospective study. Therapeutic. Tertiary referral center. Fifty consecutive adult patients undergoing a CWR-BOT between 1998 and 2009. (A) Recurrence and residual rates of cholesteatoma, (B) postoperative hygienic status of the ear, including postoperative aspect of the tympanic membrane and external ear canal integrity (EAC), (C) functional outcome, and (D) long-term safety issues. (A) The percentage of ears remaining safe without recurrent or residual disease after CWR-BOT was 96% after a mean follow-up time of 101.8 months. Recurrent cholesteatoma occurred in 2% (n = 1) and a residual cholesteatoma was detected in 2% (n = 1) of the patients. (B) A safe dry, and trouble-free graft and selfcleaning EAC was achieved in 94%. (C) The postoperative hearing results showed a gain of 1.7 dB on pure-tone average air-conduction. (D) Nonecho planar diffusion-weighted imaging (non-EP DW magnetic resonance imaging) documented the residual (n = 1) and recurrent cholesteatoma (n = 1). The 1- and 5-year imaging follow-up revealed no other recurrent or residual disease. The CWR-BOT is a safe and very effective option for treatment of problematic unstable canal wall-down mastoid cavities, resulting in dry trouble-free ears.

Vagus nerve stimulation (VNS) is an established surgical treatment for medically intractable epilepsy with more than 75 000 devices implanted worldwide. While there are many reports documenting efficacy, complications, and clinical use, there are very few reports concerning VNS battery replacement and revision surgeries. To review our experience with VNS battery replacement and revision surgery. We retrospectively reviewed 1144 consecutive VNS procedures performed by a single surgeon between 1998 and 2012. Six hundred forty-four of those procedures were the initial placement of the VNS device. These patients were then followed to determine when a battery change occurred and what type of revision or removal was necessary. In the study, 46% of patients required at least 1 or more type of battery replacement or revision surgery. The most common types of surgery were for generator battery depletion (27%), poor efficacy (9%), and lead malfunction (8%). Only 2% of patients were noted to have an infection. VNS battery replacement, revisions, and removals account for almost one-half of all VNS procedures. Our findings suggest important long-term expectations for VNS including expected complications, battery life, and other surgical issues. Review of the literature suggests that this is the first large review of VNS revisions by a single center. Our findings are important to better characterize long-term surgical expectations of VNS therapy. A significant portion of patients undergoing VNS therapy will eventually require revision.

Post-procedural acute kidney injury (AKI) is associated with significantly increased short- and long-term mortalities, and renal loss. Few studies have compared the incidence of post-procedural AKI and in-hospital mortality between 2 major modalities of revascularization - coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) - and results have been inconsistent. We generated a propensity score-matched cohort that includes a total of 286,670 hospitalizations with multi-vessel coronary disease undergoing CABG or PCI (2004-2012) from the National Inpatient Sample database. We compared incidence of AKI, AKI requiring renal replacement therapy (RRT), in-hospital mortality, hospital stay, and charges between CABG and PCI groups. The incidence of AKI after CABG was higher than PCI (8.9 vs. 4.5%, OR 2.05, 95% CI 1.99-2.12, p < 0.001). The incidence of AKI requiring RRT was also higher after CABG (1.1 vs. 0.5%, OR 2.14, 95% CI 1.96-2.34, p < 0.001). Likewise, in-hospital mortality was higher after CABG than PCI (2.0 vs. 1.4%, OR 1.44, 95% CI 1.35-1.52, p < 0.001). Among patients with pre-existing chronic kidney disease (stages I-IV), those undergoing CABG was associated with 2.0-2.3-fold higher odds of developing AKI than those undergoing PCI. The patients treated with CABG had a significantly longer hospital stay and higher hospital charges. Patients undergoing CABG are associated with (1) increased risk of developing post-procedural AKI, (2) higher likelihood of receiving RRT, and (3) worse short-term survival. Long-term renal outcome remains to be studied. © 2017 S. Karger AG, Basel.

To assess the long-term cost-effectiveness of 12 months treatment of prasugrel compared to clopidogrel in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) in the Spanish health care system. A Markov state transition model was developed to estimate health outcomes, quality adjusted life years (QALYs), life years (LY), and costs over patients' lifetimes. Clinical inputs were based on an analysis of the TRITON-TIMI 38 clinical trial. Hospital readmissions captured during the trial in a sub-study of patients from eight countries (and subsequent re-hospitalisations modelled to accrue beyond the time horizon of the trial), were assigned to Spanish diagnosis-related group payment schedules to estimate hospitalisation costs. Mean total treatment costs were ?11,427 and ?10,910 for prasugrel and clopidogrel respectively. The mean cost of the study drug was ?538 higher for prasugrel vs. clopidogrel, but rehospitalisation costs at 12 months were ?79 lower for prasugrel due to reduced rates of revascularisation. Hospitalisation costs beyond 12 months were higher with prasugrel by ?55, due to longer life expectancy (+0.071 LY and +0.054 QALYs) associated with the decreased nonfatal myocardial infarction rate in the prasugrel group. The incremental cost per life year and QALY gained with prasugrel was ?7,198, and ?9,489, respectively. Considering a willingness-to-pay threshold of ?30,000/QALY gained in the Spanish setting, prasugrel represents a cost-effective option in comparison with clopidogrel among patients with ACS undergoing PCI.

Chronic pain in patients with advanced cancer poses a serious clinical challenge. The Δ9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray (U.S. Adopted Name, nabiximols; Sativex(®)) is a novel cannabinoid formulation currently undergoing investigation as an adjuvant therapy for this treatment group. This follow-up study investigated the long-term safety and tolerability of THC/CBD spray and THC spray in relieving pain in patients with advanced cancer. In total, 43 patients with cancer-related pain experiencing inadequate analgesia despite chronic opioid dosing, who had participated in a previous three-arm (THC/CBD spray, THC spray, or placebo), two-week parent randomized controlled trial, entered this open-label, multicenter, follow-up study. Patients self-titrated THC/CBD spray (n=39) or THC spray (n=4) to symptom relief or maximum dose and were regularly reviewed for safety, tolerability, and evidence of clinical benefit. The efficacy end point of change from baseline in mean Brief Pain Inventory-Short Form scores for "pain severity" and "worst pain" domains showed a decrease (i.e., improvement) at each visit in the THC/CBD spray patients. Similarly, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 scores showed a decrease (i.e., improvement) from baseline in the domains of insomnia, pain, and fatigue. No new safety concerns associated with the extended use of THC/CBD spray arose from this study. This study showed that the long-term use of THC/CBD spray was generally well tolerated, with no evidence of a loss of effect for the relief of cancer-related pain with long-term use. Furthermore, patients who kept using the study medication did not seek to increase their dose of this or other pain-relieving medication over time, suggesting that the adjuvant use of cannabinoids in cancer-related pain could provide useful benefit.

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.

Studies investigating long-term health conditions in patients with craniopharyngioma are limited by short follow-up durations and generally do not compare long-term health effects according to initial craniopharyngioma treatment approach. In addition, studies comparing long-term health conditions between patients with childhood- and adult-onset craniopharyngioma report conflicting results. The objective of this study was to analyse a full spectrum of long-term health effects in patients with craniopharyngioma according to initial treatment approach and age group at craniopharyngioma presentation. Cross-sectional study based on retrospective data. We studied a single-centre cohort of 128 patients with craniopharyngioma treated from 1980 onwards (63 patients with childhood-onset disease). Median follow-up since craniopharyngioma presentation was 13 years (interquartile range: 5-23 years). Initial craniopharyngioma treatment approaches included gross total resection ( n  = 25), subtotal resection without radiotherapy ( n  = 44), subtotal resection with radiotherapy ( n  = 25), cyst aspiration without radiotherapy ( n  = 8), and 90 Yttrium brachytherapy ( n  = 21). Pituitary hormone deficiencies (98%), visual disturbances (75%) and obesity (56%) were the most common long-term health conditions observed. Different initial craniopharyngioma treatment approaches resulted in similar long-term health effects. Patients with childhood-onset craniopharyngioma experienced significantly more growth hormone deficiency, diabetes insipidus, panhypopituitarism, morbid obesity, epilepsy and psychiatric conditions compared with patients with adult-onset disease. Recurrence-/progression-free survival was significantly lower after initial craniopharyngioma treatment with cyst aspiration compared with other therapeutic approaches. Survival was similar between patients with childhood- and adult-onset craniopharyngioma. Long-term health conditions were comparable after different initial craniopharyngioma treatment approaches and were generally more frequent in patients with childhood- compared with adult-onset disease. © 2017 European Society of Endocrinology.

Sarcosine, an N-methyl-d-aspartate receptor enhancer, can improve depression-like behavior in rodent models and depression in humans. We found that a single dose of sarcosine exerted antidepressant-like effects with rapid concomitant increases in the mammalian target of rapamycin (mTOR) signaling pathway activation and enhancement of α-amino-3-hydroxy-5-methylisoxazole-4-propionate receptor (AMPAR) membrane insertion. Sarcosine may play a crucial role in developing novel therapy for depression. For a detailed understanding of sarcosine, this study examined the effects of long-term sarcosine treatment on the forced swim test (FST), mTOR signaling, and AMPAR membrane insertion in rats. The effects of long-term sarcosine treatment were examined in naive rats and rats exposed to chronic unpredictable stress (CUS). Long-term sarcosine treatment (560mg/kg/d for 21 d) significantly ameliorated the increased immobility induced by CUS in the FST, reaffirming the potential role of sarcosine as an antidepressant for depressed patients. The same long-term treatment exhibited no such effect in naive rats despite increased mTOR activation and AMPAR membrane insertion in both groups. Our findings clearly show CUS-exposed rats are sensitive to long-term sarcosine treatment in FST and the response at the same dose is absent in naïve rats. Nevertheless, the distinct sensitivity to long-term sarcosine treatment in rats with or without CUS is not associated with the activated mTOR signaling pathway or increased AMPAR membrane insertion. Additionally, understanding the behavioral and molecular basis of distinct responses is vital important for developing personalized treatment programs to increase the probability of success when treating depression.

To investigate the association between Agent Orange (AO) exposure and long-term prostate cancer (PC) outcomes. Data from 1,882 men undergoing radical prostatectomy for PC between 1988 and 2011 at Veterans Affairs Health Care Facilities were analyzed from the Shared Equal Access Regional Cancer Hospital database. Men were stratified by AO exposure (binary). Associations between AO exposure and biopsy and pathologic Gleason sum (GS) and pathologic stage were determined by logistic regression models adjusted for preoperative characteristics. Hazard ratios for biochemical recurrence (BCR), secondary treatment, metastases, and PC-specific mortality were determined by Cox models adjusted for preoperative characteristics. There were 333 (17.7%) men with AO exposure. AO-exposed men were younger (median 59 vs. 62 y), had lower preoperative prostate-specific antigen levels (5.8 vs. 6.7 ng/ml), lower clinical category (25% vs. 38% palpable), and higher body mass index (28.2 vs. 27.6 kg/m(2)), all P<0.01. Biopsy GS, pathologic GS, positive surgical margins, lymph node positivity, and extracapsular extension did not differ with AO exposure. At a median follow-up of 85 months, 702 (37.4%) patients had BCR, 603 (32.2%) patients received secondary treatment, 78 (4.1%) had metastases, and 39 (2.1%) died of PC. On multivariable analysis, AO exposure was not associated with BCR, secondary treatment, metastases, or PC mortality. AO exposure was not associated with worse preoperative characteristics such as elevated prostate-specific antigen levels or biopsy GS nor with BCR, secondary treatment, metastases, or PC death. Thus, as data on AO-exposed men mature, possible differences in PC outcomes observed previously are no longer apparent. Copyright © 2015 Elsevier Inc. All rights reserved.

Prosthetic valve endocarditis caused by Candida spp. (PVE-C) is rare and devastating, with international guidelines based on expert recommendations supporting the combination of surgery and subsequent azole treatment. We retrospectively analyzed PVE-C cases collected in Spain and France between 2001 and 2015, with a focus on management and outcome. Forty-six cases were followed up for a median of 9 months. Twenty-two patients (48%) had a history of endocarditis, 30 cases (65%) were nosocomial or healthcare related, and 9 (20%) patients were intravenous drug users. "Induction" therapy consisted mainly of liposomal amphotericin B (L-amB)-based (n = 21) or echinocandin-based therapy (n = 13). Overall, 19 patients (41%) were operated on. Patients <66 years old and without cardiac failure were more likely to undergo cardiac surgery (adjusted odds ratios [aORs], 6.80 [95% confidence interval [CI], 1.59-29.13] and 10.92 [1.15-104.06], respectively). Surgery was not associated with better survival rates at 6 months. Patients who received L-amB alone had a better 6-month survival rate than those who received an echinocandin alone (aOR, 13.52; 95% CI, 1.03-838.10). "Maintenance" fluconazole therapy, prescribed in 21 patients for a median duration of 13 months (range, 2-84 months), led to minor adverse effects. L-amB induction treatment improves survival in patients with PVE-C. Medical treatment followed by long-term maintenance fluconazole may be the best treatment option for frail patients. © The Author 2017.

Uncovering Camouflage: Amygdala Activation Predicts Long-Term Memory of Induced Perceptual Insight

What brain mechanisms underlie learning of new knowledge from single events? We studied encoding in long-term memory of a unique type of one-shot experience, induced perceptual insight. While undergoing an fMRI brain scan, participants viewed degraded images of real-world pictures where the underlying objects were hard to recognize (‘camouflage’), followed by brief exposures to the original images (‘solution’), which led to induced insight (“Aha!”). A week later, participants’ memory was tested; a solution image was classified as ‘remembered’ if detailed perceptual knowledge was elicited from the camouflage image alone. During encoding, subsequently remembered images enjoyed higher activity in mid-level visual cortex and medial frontal cortex, but most pronouncedly in the amygdala, whose activity could be used to predict which solutions will remain in long-term memory. Our findings extend the known roles of amygdala in memory to include promoting of long-term memory of the sudden reorganization of internal representations. PMID:21382558

Mid-term right ventricular (RV) reverse remodeling after treatment in patients with pulmonary hypertension (PH) is associated with long-term outcome as well as baseline RV remodeling. However, baseline factors influencing mid-term RV reverse remodeling after treatment and its prognostic capability remain unclear. We studied 54 PH patients. Mid-term RV remodeling was assessed in terms of the RV area, which was traced planimetrically at the end-systole (RVESA). RV reverse remodeling was defined as a relative decrease in the RVESA of at least 15% at 10.2 ± 9.4 months after treatment. Long-term follow-up was 5 years. Adverse events occurred in ten patients (19%) and mid-term RV reverse remodeling after treatment was observed in 37 (69%). Patients with mid-term RV reverse remodeling had more favorable long-term outcomes than those without (log-rank: p = 0.01). Multivariate logistic regression analysis showed that RV relative wall thickness (RV-RWT), as calculated as RV free-wall thickness/RV basal linear dimension at end-diastole, was an independent predictor of mid-term RV reverse remodeling (OR 1.334; 95% CI, 1.039-1.713; p = 0.03). Moreover, patients with RV-RWT ≥0.21 showed better long-term outcomes than did those without (log-rank p = 0.03), while those with RV-RWT ≥0.21 and mid-term RV reverse remodeling had the best long-term outcomes. Patients with RV-RWT <0.21 and without mid-term RV reverse remodeling, on the other hand, had worse long-term outcomes than other sub-groups. In conclusions, RV-RWT could predict mid-term RV reverse remodeling after treatment in PH patients, and was associated with long-term outcomes. Our finding may have clinical implications for better management of PH patients.

Stress-related illnesses are a growing health problem in the Western world; which also has economic significance for society. As a consequence; there is a growing demand for effective treatments. The study investigates the long-term efficacy of the Nacadia ® nature-based therapy (NNBT) by comparing it to the efficacy of a validated cognitive behavioral therapy, called STreSS. The study is designed as a randomized controlled trial in which 84 participants are randomly allocated between the treatments. Long-term efficacy is investigated through data extracts from the national database of Statistics Denmark on the sick leave and the health-care consumption. The results show that both the NNBT and the STreSS lead to a significant decrease in number of contacts with a general practitioner in the period from twelve months prior to treatment to twelve months after treatment; and, a significant decrease in long-term sick leave from the month prior to treatment to twelve months after treatment. The positive long-term effects provide validation for the NNBT as an efficient treatment of stress-related illnesses.

To evaluate short-term versus long-term single prophylactic antibiotic for elective gastric tumor surgery. Patients in a single surgical team undergoing elective gastric tumor surgery were enrolled from November 2009 to December 2010. The included patients were aged from 18 to 70 years without conditions as severe comorbidity, preoperative infectious diseases, antibiotic administration 48 h before surgery, exploratory laparotomy only or combined colorectal resection, neoadjuvant chemotherapy, or steroid administration before surgery. The overall and infection-related postoperative complications and also economic outcomes were analyzed. The software SPSS 17.0 and TreeAge Pro 2007 were used for statistics. Patients (n=158 (45 vs. 113)) were enrolled in short-term and long-term groups. No death cases occurred. Overall postoperative complication rates were 8.9% and 8.0%, respectively (p=1.000). The rates of infection related complications were 8.9% and 4.4%, respectively (p=0.231). No surgical site infection (SSI) occurred in the short-term group, whereas SSI was 1.8% in the long-term group. Total hospitalization cost (THC) of short-term branch was 36,557RMB per patients and preferable against 39,523RMB of long-term branch. Incremental cost-effectiveness analysis showed there was a 10 times interval between the extra healthcare expenditure of benefit and harm. Short-term administration did not increase the risk of postoperative complications and was more cost-effective.

We determined the long-term outcome in patients with superficial bladder cancer (Ta and T1) undergoing routine second transurethral bladder tumor resection (ReTURB) in regard to recurrence and progression. We performed an inception cohort study of 124 consecutive patients with superficial bladder cancer undergoing transurethral resection and routine ReTURB (83) between November 1993 and October 1995 at a German university hospital. Immediately after transurethral resection all lesions were documented on a designed bladder map. ReTURB of the scar from initial resection and other suspicious lesions was performed at a mean of 7 weeks. Patients were followed until recurrence or death, or a minimum of 5 years. Residual tumor was found in 33% of all ReTURB cases, including 27% of Ta and 53% of T1 disease, and in 81% at the initial resection site. Five of the 83 patients underwent radical cystectomy due to ReTURB findings. The estimated risk of recurrence after years 1 to 3 was 18%, 29% and 32%, respectively. After 5 years 63% of the patients undergoing ReTURB were still disease-free (mean recurrence-free survival 62 months, median 87). Progression to muscle invasive disease was observed in only 2 patients (3%) after a mean observation of 61 months. These data suggest a favorable outcome regarding recurrence and progression in patients with superficial bladder cancer who undergo ReTURB. ReTURB is suggested at least in those at high risk when bladder preservation is intended.

To analyze the long-term results and risk factors of surgical revascularization in patients with ischemic heart disease (IHD) and left ventricular dysfunction (LVD). From January 2003 to July 2013, 2 132 patients underwent coronary artery bypass grafting (CABG) in our institution. Among them, 318 patients with LVD[left ventricular ejection fraction (LVEF) ≤50%]were included in the final study. There were 26 6 male and 52 female patients with age from 36 to 83 (63±9) years old. 76 patients underwent off-pump CABG (OPCAB) and 242 patients underwent conventional CABG (CCABG). Risk factors, perioperative results and follow-up data were collected and analyzed with cox hazard ratio model. Among 318 patients, 6 cases died of the operation with a hospital mortality of 1.9%. With follow-up time from 1 to 128(45.5±32.4)months, 25 patients were lost of follow-up, causing a follow-up rate of 92.0%. Among the 287 cases with long-term follow-up results, all-cause death, cardiogenic death and re-hospitalization due to heart failure were 14.6% (42/287), 5.9%(17/287), 14.6% (42/287), respectively. Re-revascularization rate, recurrent angina and myocardial infarction rate and cerebral incidence were 3.5%(10/287), 13.6% (39/287), 1.7%(5/287), respectively. The five-year survival rate was 85.6%. With all-cause death as the endpoint, preoperative LVEF (HR=0.943, 95%CI: 0.893-0.995, P=0.031) and perioperative implantation of IABP (HR=2.509, 95%CI: 1.051-5.992, P=0.038) emerged as the risk factors that affected the long term survival. The five-year survival rate of patients with severe LVD (LVEF≤35%) was significantly lower than that of patients with mild to moderate LVD (35%

Studies evaluating the outcomes of patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) are scarce, particularly in China. The purpose of present study was therefore to compare the impact of off-hours and on-hours admission on clinical outcomes in STEMI patients from China.We retrospectively analyzed 1594 patients from 4 hospitals. Of these, 903 patients (56.65%) were admitted during off-hours (weekdays from 18:00 to 08:00, weekends and holidays) and 691 (43.35%) were during on-hours (weekdays from 08:00 to 18:00).Patients admitted during off-hours had higher thrombolysis in myocardial infarction risk score (4.67 ± 2.27 vs 4.39 ± 2.10, P = 0.012) and longer door-to-balloon time (72 [50-96] vs 64 [42-92] minutes, P < 0.001) than those admitted during on-hours. Off-hours admission had no association with in-hospital (unadjusted odds ratio 2.069, 95% confidence interval [CI] 0.956-4.480, P = 0.060) and long-term mortality (unadjusted hazards ratio [HR] 1.469, 95%CI 0.993-2.173, P = 0.054), even after adjustment for confounders. However, long-term outcomes, the composite of deaths and other adverse events, differed between groups with an unadjusted HR of 1.327 (95%CI, 1.102-1.599, P = 0.003), which remained significant in regression models. In a subgroup analysis, off-hours admission was associated with higher long-term mortality in the high-risk subgroup (unadjusted HR 1.965, 95%CI 1.103-3.512, P = 0.042), but not in low- and moderate-risk subgroups.This study showed no association between off-hours admission and in-hospital and long-term mortality. Stratified analysis indicated that off-hours admission was significantly associated with long-term mortality in the high-risk subgroup.

To study the effect of a iodine load on thyroid function of patients with ischaemic heart disease (IHD) and the long-term influence of unknown subclinical hyperthyroidism. Subclinical hyperthyroidism is considered an independent risk factors for cardiovascular morbidity of patients with IHD. They routinely undergo coronary angiography with iodine contrast media (ICM) which may induce or even worsen hyperthyroidism. A cross-sectional study followed by a longitudinal study on patients with subclinical hyperthyroidism. 810 consecutive IHD outpatients without known thyroid diseases or treatment with drugs influencing thyroid activity undergoing elective coronary angiography. We evaluated thyroid function either before and 1 month after ICM; patients with thyrotoxicosis at baseline or after ICM were then followed up for 1 year. 58 patients had hyperthyroidism at baseline (HB, 7.2%), independently associated to FT4 levels, thyroid nodules and family history of thyroid diseases. After ICM, the prevalence of hyperthyroidism was 81 (10%). Hyperthyroidism after ICM was positively predicted by baseline fT4 levels, thyroid nodules, age over 60, male gender, family history of thyroid diseases. Three months after ICM, 34 patients (4.2%) still showed hyperthyroidism (22 from HB, 13 treated with methimazole). One year after ICM, hyperthyroidism was still present in 20 patients (2.5%, all from HB, 13 treated). The prevalence of spontaneous subclinical hyperthyroidism in IHD is surprisingly elevated and is further increased by iodine load, particularly in patients with thyroid nodules and familial history of thyroid diseases, persisting in a not negligible number of them even after one year. © 2017 John Wiley & Sons Ltd.

We aimed to report long-term outcomes for patients undergoing per-oral endoscopic myotomy (POEM) after our initial 15-case learning curve. POEM has become an established, natural-orifice surgical approach for treating esophageal motility disorders. To date, published outcomes and comparative-effectiveness studies have included patients from the early POEM experience. Consecutive patients undergoing POEM after our initial 15 cases, with a minimum of 1-year postoperative follow-up, were included. Treatment success was defined as an Eckardt score ≤3 without reintervention. Gastroesophageal reflux was defined by abnormal pH-testing or reflux esophagitis >Los Angeles grade A. Between January 2012 and March 2015, 115 patients underwent POEM at a single, high-volume center. Operative time was 101 ± 29 minutes, with 95% (109/115) of patients discharged on postoperative day 1. Clavien-Dindo grade III complications occurred in 2.7%, one of which required diagnostic laparoscopy to rule out Veress needle injury to the gall bladder. The rate of grade I complications was 15.2%. At an average of 2.4 years post-POEM (range 12-52 months), the overall success rate was 92%. Objective evidence of reflux was present in 40% for all patients and 33% for patients with a body mass index <35 kg/m and no hiatal hernia. POEM performed by experienced surgeons provided durable symptomatic relief in 94% of patients with nonspastic achalasia and 90% of patients with type 3 achalasia/spastic esophageal motility disorders, with a low rate of complications. The rate of gastroesophageal reflux was comparable with prior studies of both POEM and laparoscopic Heller myotomy.

Background Many modalities have been used to ablate Barrett's oesophagus (BO). However, long term results and comparative effectiveness are unknown. Aims Our aim was to compare the long term efficacy of achieving complete reversal (endoscopic and histological) between multipolar electrocoagulation (MPEC) and argon plasma coagulation (APC) in BO patients and assess factors influencing successful ablation. Methods Patients with BO, 2–6 cm long, underwent 24 hour pH testing on proton pump inhibitor (PPI) therapy. Patients were then randomised by BO length to undergo ablation with MPEC or APC every 4–8 weeks until endoscopic reversal or maximal of six treatment sessions. Results Thirty five BO patients have been followed for at least two years following endoscopic ablation, 16 treated with MPEC and 19 with APC. There was complete reversal of BO in 24 patients (69%); 75% with MPEC and 63% with APC (p = 0.49). There was no difference in the number of sessions required in the two groups. There was no difference in age, pH results, BO length, PPI dose, or hiatal hernia size between patients with and without complete reversal. One patient developed an oesophageal stricture but there were no major complications such as bleeding or perforation. Conclusions In BO patients treated with MPEC or APC in combination with acid suppression, at long term follow up, complete reversal of BO can be maintained in approximately 70% of patients, irrespective of the technique. There are no predictors associated with achieving complete reversal of BO. Continued surveillance is still indicated in the post ablative setting. As yet, these techniques are not ready for clinical application (other than for high grade dysplasia or early oesophageal adenocarcinoma) and cannot be offered outside the research arena.

Previous work in our laboratory has shown that long-term treatment with Vigconic 28 (VI-28), a Yang-invigorating Chinese herbal formula used for the promotion of overall wellness in Chinese medicine, can enhance the mitochondrial functional ability and antioxidant capacity in various tissues of both male and female rats. To investigate whether the VI-28 treatment regimen could afford tissue protection against oxidative injury, the effects of long-term VI-28 treatment (80 or 240 mg/kg/d x 30) on oxidative stress-induced tissue damage in various organs (brain, heart, liver, and kidney) were examined in female rats. The results indicated that long-term VI-28 treatment invariably protected against oxidative tissue damage in the rat models of cerebral/myocardial ischemia-reperfusion injury, CCl4 hepatotoxicity, and gentamicin nephrotoxicity. The tissue protection was associated with increases in the levels and activities of mitochondrial antioxidant components as well as with the preservation of mitochondrial structural integrity. This was evidenced by decreases in the sensitivity of mitochondria to Ca2+-induced permeability transition, and in the levels of mitochondrial malondialdehyde production, Ca2+ loading, and cytochrome c release in the tissues examined. Interestingly, the VI-28 treatment increased red cell CuZn-superoxide dismutase (CuZn-SOD) levels, and these levels correlated positively with the degree of tissue protection afforded by long-term VI-28 treatment in rats. The generalized tissue protection afforded by long-term VI-28 treatment may have clinical implications in the prevention of age-related diseases, and VI-28 treatment may possibly delay the aging process.

The long-term skeletal effects of Class II treatment in growing individuals using high-pull facebow headgear and fixed edgewise appliances have not been reported. The purpose of this study was to evaluate the long-term skeletal effects of treatment using high-pull headgear followed by fixed orthodontic appliances compared to an untreated control group. Changes in anteroposterior and vertical cephalometric measurements of 42 Class II subjects (n = 21, mean age = 10.7 years) before treatment, after headgear correction to Class I molar relationship, after treatment with fixed appliances, and after long-term retention (mean 4.1 years), were compared to similar changes in a matched control group (n = 21, mean age = 10.9 years) by multivariable linear regression models. Compared to control, the study group displayed significant long-term horizontal restriction of A-point (SNA = -1.925°, P < .0001; FH-NA = -3.042°, P < .0001; linear measurement A-point to Vertical Reference = -3.859 mm, P < .0001) and reduction of the ANB angle (-1.767°, P < .0001), with no effect on mandibular horizontal growth or maxillary and mandibular vertical skeletal changes. A-point horizontal restriction and forward mandibular horizontal growth accompanied the study group correction to Class I molar, and these changes were stable long term. One phase treatment for Class II malocclusion with high-pull headgear followed by fixed orthodontic appliances resulted in correction to Class I molar through restriction of horizontal maxillary growth with continued horizontal mandibular growth and vertical skeletal changes unaffected. The anteroposterior molar correction and skeletal effects of this treatment were stable long term.

Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. A retrospective analysis of 43 high-risk patients who underwent concomitant surgical aortic valve replacement and mitral valve surgery from 2008 to 2012 was performed. Immediate and long term survival were assessed. There were 43 high-risk patients with severe aortic stenosis undergoing concomitant surgical aortic valve replacement and mitral valve surgery. The average age was 80 ± 6 years old. Nineteen (44%) patients had prior cardiac surgery, 15 (34.9%) patients had chronic obstructive lung disease, and 39 (91%) patients were in congestive heart failure. The mean Society of Thoracic Surgeons Predicted Risk of Mortality for isolated surgical aortic valve replacement for the cohort was 10.1% ± 6.4%. Five patients (11.6%) died during the index admission and/or within thirty days of surgery. Mortality rate was 25% at six months, 35% at 1 year and 45% at 2 years. There was no correlation between individual preoperative risk factors and mortality. High-risk patients with severe aortic stenosis and mitral valve disease undergoing concomitant surgical aortic valve replacement and mitral valve surgery may have similar long term survival as that described for such patients undergoing TAVR. Surgical correction of double valvular disease in this patient population may not confer mortality benefit compared to TAVR alone.

To evaluate the effect of long-term treatment with tetracycline and niacinamide on antibody production in dogs by measuring postvaccinal serum concentrations of antibodies against canine parvovirus and canine distemper virus. 10 dogs receiving long-term treatment with tetracycline and niacinamide (treatment group) and 10 healthy dogs (control group). The treatment group included 9 dogs with discoid lupus erythematosus and 1 dog with pemphigus foliaceus on long-term treatment (> 12 months) with tetracycline and niacinamide. The control group included 10 healthy dogs with no clinical signs of disease and no administered medications for the past 3 months. Blood samples were obtained from all dogs by jugular venipuncture. Serum antibody titers against canine parvovirus and canine distemper virus antigens were measured, using hemaglutination inhibition and serum neutralization, respectively, and compared between groups. A significant difference in antibody titers between treatment- and control-group dogs was not found. All dogs had protective antibody titers against canine distemper virus, and 8 of 10 dogs from each group had protective titers against canine parvovirus infection. These results provide evidence that long-term treatment with tetracycline and niacinamide does not interfere with routine vaccinations and thus does not seem to influence antibody production in dogs.

Surgical pain is managed with multi-modal anaesthesia in total hip replacement (THR) and total knee replacement (TKR). It is unclear whether including local anaesthetic infiltration before wound closure provides additional pain control. We performed a systematic review of randomised controlled trials of local anaesthetic infiltration in patients receiving THR or TKR. We searched MEDLINE, Embase and Cochrane CENTRAL to December 2012. Two reviewers screened abstracts, extracted data, and contacted authors for unpublished outcomes and data. Outcomes collected were post-operative pain at rest and during activity after 24 and 48 hours, opioid requirement, mobilisation, hospital stay and complications. When feasible, we estimated pooled treatment effects using random effects meta-analyses. In 13 studies including 909 patients undergoing THR, patients receiving local anaesthetic infiltration experienced a greater reduction in pain at 24 hours at rest by standardised mean difference (SMD) -0.61 (95% CI -1.05, -0.16; p = 0.008) and by SMD -0.43 (95% CI -0.78 -0.09; p = 0.014) at 48 hours during activity.In TKR, diverse multi-modal regimens were reported. In 23 studies including 1439 patients undergoing TKR, local anaesthetic infiltration reduced pain on average by SMD -0.40 (95% CI -0.58, -0.22; p < 0.001) at 24 hours at rest and by SMD -0.27 (95% CI -0.50, -0.05; p = 0.018) at 48 hours during activity, compared with patients receiving no infiltration or placebo. There was evidence of a larger reduction in studies delivering additional local anaesthetic after wound closure. There was no evidence of pain control additional to that provided by femoral nerve block.Patients receiving local anaesthetic infiltration spent on average an estimated 0.83 (95% CI 1.54, 0.12; p = 0.022) and 0.87 (95% CI 1.62, 0.11; p = 0.025) fewer days in hospital after THR and TKR respectively, had reduced opioid consumption, earlier mobilisation, and lower incidence of vomiting.Few studies reported long-term outcomes. Local anaesthetic infiltration is effective in reducing short-term pain and hospital stay in patients receiving THR and TKR. Studies should assess whether local anaesthetic infiltration can prevent long-term pain. Enhanced pain control with additional analgesia through a catheter should be weighed against a possible infection risk.

The infant gut microbiota undergoes dramatic changes during the first 2 years of life. The acquisition and development of this population can be influenced by numerous factors, and antibiotic treatment has been suggested as one of the most significant. Despite this, however, there have been relatively few studies which have investigated the short-term recovery of the infant gut microbiota following antibiotic treatment. The aim of this study was to use high-throughput sequencing (employing both 16S rRNA and rpoB-specific primers) and quantitative PCR to compare the gut microbiota of nine infants who underwent parenteral antibiotic treatment with ampicillin and gentamicin (within 48 h of birth), 4 and 8 weeks after the conclusion of treatment, relative to that of nine matched healthy controls. The investigation revealed that the gut microbiota of the antibiotic-treated infants had significantly higher proportions of Proteobacteria (P = 0.0049) and significantly lower proportions of Actinobacteria (P = 0.00001) (and the associated genus Bifidobacterium [P = 0.0132]) as well as the genus Lactobacillus (P = 0.0182) than the untreated controls 4 weeks after the cessation of treatment. By week 8, the Proteobacteria levels remained significantly higher in the treated infants (P = 0.0049), but the Actinobacteria, Bifidobacterium, and Lactobacillus levels had recovered and were similar to those in the control samples. Despite this recovery of total Bifidobacterium numbers, rpoB-targeted pyrosequencing revealed that the number of different Bifidobacterium species present in the antibiotic-treated infants was reduced. It is thus apparent that the combined use of ampicillin and gentamicin in early life can have significant effects on the evolution of the infant gut microbiota, the long-term health implications of which remain unknown.

Acute limb ischemia (ALI) is a highly morbid and fatal vascular emergency with little known about contemporary, long-term patient outcomes. The goal was to determine predictors of long-term mortality and amputation after open and endovascular treatment of ALI. A retrospective review of ALI patients at a single institution from 2005 to 2011 was performed to determine the impact of revascularization technique on 5-year mortality and amputation. For each main outcome 2 multivariable models were developed; the first adjusted for preoperative clinical presentation and procedure type, the second also adjusted for postoperative adverse events (AEs). A total of 445 limbs in 411 patients were treated for ALI. Interventions included surgical thrombectomy (48%), emergent bypass (18%), and endovascular revascularization (34%). Mean age was 68 ± 15 years, 54% were male, and 23% had cancer. Most patients presented with Rutherford classification IIa (54%) or IIb (39%). The etiology of ALI included embolism (27%), in situ thrombosis (28%), thrombosed bypass grafts (32%), and thrombosed stents (13%). Patients treated with open procedures had significantly more advanced ischemia and higher rates of postoperative respiratory failure, whereas patients undergoing endovascular interventions had higher rates of technical failure. Rates of postprocedural bleeding and cardiac events were similar between both treatments. Excluding Rutherford class III patients (n = 12), overall 5-year mortality was 54% (stratified by treatment, 65% for thrombectomy, 63% for bypass, and 36% for endovascular, P < 0.001); 5-year amputation was 28% (stratified by treatment, 18% for thrombectomy, 27% for bypass, and 17% for endovascular, P = 0.042). Adjusting for comorbidities, patient presentation, AEs, and treatment method, the risk of mortality increased with age (hazard ratio [HR] = 1.04, P < 0.001), female gender (HR = 1.50, P = 0.031), cancer (HR = 2.19, P < 0.001), fasciotomy (HR = 1.69, P = 0.204) in situ thrombosis or embolic etiology (HR = 1.73, P = 0.007), cardiac AEs (HR = 2.25, P < 0.001), respiratory failure (HR = 2.72, P < 0.001), renal failure (HR = 4.70, P < 0.001), and hemorrhagic events (HR = 2.25, P = 0.003). Risk of amputation increased with advanced ischemia (Rutherford IIb compared with IIa, HR = 2.57, P < 0.001), thrombosed bypass etiology (HR = 3.53, P = 0.002), open revascularization (OR; HR = 1.95, P = 0.022), and technical failure of primary intervention (HR = 6.01, P < 0.001). After the treatment of ALI, long-term mortality and amputation rates were greater in patients treated with open techniques; OR patients presented with a higher number of comorbidities and advanced ischemia, while also experiencing a higher rate of major postoperative complications. Overall, mortality rates remained high and were most strongly associated with baseline comorbidities, acuity of presentation, and perioperative AEs, particularly respiratory failure. Comparatively, amputation risk was most highly associated with advanced ischemia, thrombosed bypass, and failure of the initial revascularization procedure. Copyright © 2016 Elsevier Inc.

Long-term benzodiazepine (BDZ) use and dependence affect cognitive functioning adversely and partly irreversibly. Emerging evidence suggests that pregabalin (PGB) might be a safe and efficacious treatment of long-term BDZ use. The aim of the present study was to investigate the changes in several core cognitive functions after successful treatment of long-term BDZ use and dependence with PGB. Fourteen patients with long-term BDZ use (mean duration >15 years) underwent neuropsychological assessment with the mini-mental state examination and four tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB) battery before the initiation of PGB treatment and at a two months follow-up after the cessation of BDZs. Patients' CANTAB percentile score distributions were compared with normative CANTAB data. Patients improved on cognitive measures of global cognitive functioning, time orientation, psychomotor speed, and visuospatial memory and learning with strong effect sizes. By contrast, they failed to improve on measures of attentional flexibility. Despite their significant improvement, patients' scores on most tests remained still at the lower percentiles of CANTAB normative scores. Although preliminary, our findings suggest that successful treatment of long-term BDZ use with PGB is associated with a substantial, though only partial, recovery of BDZ-compromised neuropsychological functioning, at least at a 2-month follow-up.

2017-08-01

Periodontitis treatments usually require local administration of antimicrobial drugs with the aim to reduce the bacterial load inside the periodontal pocket. Effective pharmaceutical treatments may require sustained local drug release for several days in the site of interest. Currently available solutions are still not able to fulfill the clinical need for high-quality treatments, mainly in terms of release profiles and patients' comfort. This work aims to fill this gap through the development of an in situ gelling system, capable to achieve controlled and sustained release of antimicrobial agents for medium-to-long-term treatments. The system is composed of micrometer-sized β-cyclodextrin-based hydrogel (bCD-Jef-MPs), featured by a strong hydrophilic character, suspended in a synthetic block-co-polymer solution (Poloxamer 407), which is capable to undergo rapid thermally induced sol-gel phase transition at body temperature. The chemical structure of bCD-Jef-MPs was confirmed by cross-correlating data from Fourier transform infrared (FTIR) spectroscopy, swelling test, and degradation kinetics. The thermally induced sol-gel phase transition is demonstrated by rheometric tests. The effectiveness of the described system to achieve sustained release of antimicrobial agents is demonstrated in vitro, using chlorhexidine digluconate as a drug model. The results achieved in this work disclose the potential of the mentioned system in effectively treating periodontitis lesions. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Increased heartbeat perception accuracy (HBP-accuracy) may contribute to the pathogenesis of Panic Disorder (PD) without or with Agoraphobia (PDA). Extant research suggests that HBP-accuracy is a rather stable individual characteristic, moreover predictive of worse long-term outcome in PD/PDA patients. However, it remains still unexplored whether HBP-accuracy adversely affects patients' short-term outcome after structured cognitive behaviour therapy (CBT) for PD/PDA. To explore the potential association between HBP-accuracy and the short-term outcome of a structured brief-CBT for the acute treatment of PDA. We assessed baseline HBP-accuracy using the "mental tracking" paradigm in 25 consecutive medication-free, CBT-naive PDA patients. Patients then underwent a structured, protocol-based, 8-session CBT by the same therapist. Outcome measures included the number of panic attacks during the past week, the Agoraphobic Cognitions Questionnaire (ACQ), and the Mobility Inventory-Alone subscale (MI-alone). No association emerged between baseline HBP-accuracy and posttreatment changes concerning number of panic attacks. Moreover, higher baseline HBP-accuracy was associated with significantly larger reductions in the scores of the ACQ and the MI-alone scales. Our results suggest that in PDA patients undergoing structured brief-CBT for the acute treatment of their symptoms, higher baseline HBP-accuracy is not associated with worse short-term outcome concerning panic attacks. Furthermore, higher baseline HBP-accuracy may be associated with enhanced therapeutic gains in agoraphobic cognitions and behaviours.

In the early 1950s, Rubin H. Flocks of the University of Iowa began to treat prostate cancer patients with colloidal gold (Au(198)) therapy, evolving his technique over nearly 25 years in 1515 patients. We reviewed the long-term outcomes of Flocks' prostate cancer patients as compared to those patients treated by other methods at the University of Iowa before Flocks' chairmanship. We reviewed archived patient records, Flocks' published data, and long-term survival data from the Iowa Tumor Registry to determine short- and long-term outcomes of Flocks' work with colloidal gold. We also reviewed the literature of Flocks' time to compare his outcomes against those of his contemporaries. The use of colloidal gold, either as primary or adjunctive therapy, provided short- and long-term survival benefit for the majority of Flocks' patients as compared to historical treatment options (p < 0.001). Flocks' use of colloidal gold for the treatment of locally advanced prostate cancer offered short- and long-term survival benefits compared to other contemporary treatments.

To determine the short-term and long-term treatment-effects of botulinum toxin type A in simple motor tics, we analyzed 15 consecutive patients (18 tics) with simple motor tics that were treated every 3 months with injections of BTX-A. Efficacy (rated on a 4-level scale) and duration of effect of the first 2 and last 2 (if treated 5 times or more) treatments were recorded, as well as latency of response, changes of premonitory urges (PMUs) and possible side effects. Total number of treatments for each tic varied from 2 to 50 (mean 11, median 6). In 16 of 18 tics (89%) short-term efficacy was reported successful (good or moderate). Long-term efficacy was reported in 12 tics of which 11 showed similar or even increased beneficial effects. Premonitory urge (PMU) was reported in 8 patients (53%). PMU, if present, lessened or disappeared after treatment with BTX-A. A permanent remission of the treated tic was seen in 3 patients with a maximum follow-up of 10 years. BTX-A appears a safe and effective treatment for simple motor tics and retains its efficacy after long-term treatment. BTX may also induce permanent remission of the treated tics and effects of BTX are not restricted to merely motor behaviour.

The primary aim of this pilot study was to prospectively assess a flowchart to screen and diagnose paced patients (pts) affected by sleep apnoeas, by crosschecking indexes derived from pacemakers (minute ventilation sensor on-board) with Sleep-Lab Polygraphy (PG) outcomes. Secondarily, "smoothed" long-term pacemaker indexes (all the information between two consecutive follow-up visits) have been retrospectively compared vs. standard short-term pacemaker indexes (last 24h) at each follow-up (FU) visit, to test their correlation and diagnostic concordance. Data from long-term FU of 61 paced pts were collected. At each visit, the standard short-term apnoea+hypopnoea (PM_AHI) index was retrieved from the pacemaker memory. Patients showing PM_AHI ≥ 30 at least once during FU were proposed to undergo a PG for diagnostic confirmation. Smoothed pacemaker (PM_SAHI) indexes were calculated by averaging the overall number of apnoeas/hypopnoeas over the period between two FU visits, and retrospectively compared with standard PM_AHI. Data were available from 609 consecutive visits (overall 4.64 ± 1.78 years FU). PM_AHI indexes were positive during FU in 40/61 pts (65.6%); 26/40 pts (65%) accepted to undergo a PG recording; Sleep-Lab confirmed positivity in 22/26 pts (84.6% positive predictive value for PM_AHI). A strong correlation (r=0.73) and a high level of concordance were found between smoothed and standard indexes (multivariate analysis, Cohen's-k and Z-score tests). Pacemaker-derived indexes may help in screening paced pts potentially affected by sleep apnoeas. Long-term "smoothed" apnoea indexes could improve the accuracy of pacemaker screening capability, even though this hypothesis must be prospectively confirmed by larger studies.

Patients undergoing urgent heart transplantation (HT) have a poorer prognosis and more long-term complications. The objective of this study was to compare the preoperative course in patients undergoing urgent HT according to the need for preoperative intra-aortic balloon counterpulsation (IABP). We studied 102 consecutive patients including 23 patients with IABP who underwent urgent HT between January 2000 and September 2006. We excluded patients who received combination transplants, those who underwent repeat HT, and pediatric patients who underwent HT. The statistical methods used were the t test for quantitative variables and the chi(2) test for qualitative variables. A logistic regression model was constructed to assess the possible relationship between IABP and other variables on premature death within 30 days after HT. Mean (SD) patient-age was 50 (10) years. No significant differences were observed in baseline characteristics between the IABP and the non-IAPB groups. The IABP patient group had higher rates of acute graft failure (45.5% vs 35.4%; P = .46) and premature death (18.8% vs 14.8%; P = .67) and shorter long-term survival (40.6 [34.9] vs 54.5 [43.7] mo; P = .30). Multivariate analysis demonstrated no association between the need for IABP and increased frequency of premature death. Use of IABP is not associated with premature or late death. We recommend use of IABP in patients with acute decompensated heart failure to stabilize them before HT.

Gastro-oesophageal reflux disease (GORD) is a common condition with 3% to 33% of people from different parts of the world suffering from GORD. There is considerable uncertainty about whether people with GORD should receive an operation or medical treatment for controlling the condition. To assess the benefits and harms of laparoscopic fundoplication versus medical treatment for people with gastro-oesophageal reflux disease. We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group (UGPD) Trials Register (June 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 6, 2015), Ovid MEDLINE (1966 to June 2015), and EMBASE (1980 to June 2015) to identify randomised controlled trials. We also searched the references of included trials to identify further trials. We considered only randomised controlled trials (RCT) comparing laparoscopic fundoplication with medical treatment in people with GORD irrespective of language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and independently extracted data. We calculated the risk ratio (RR) or standardised mean difference (SMD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models with RevMan 5 based on available case analysis. Four studies met the inclusion criteria for the review, and provided information on one or more outcomes for the review. A total of 1160 participants in the four RCTs were either randomly assigned to laparoscopic fundoplication (589 participants) or medical treatment with proton pump inhibitors (571 participants). All the trials included participants who had had reflux symptoms for at least six months and had received long-term acid suppressive therapy. All the trials included only participants who could undergo surgery if randomised to the surgery arm. All of the trials were at high risk of bias. The overall quality of evidence was low or very low. None of the trials reported long-term health-related quality of life (HRQoL) or GORD-specific quality of life (QoL).The difference between laparoscopic fundoplication and medical treatment was imprecise for overall short-term HRQOL (SMD 0.14, 95% CI -0.02 to 0.30; participants = 605; studies = 3), medium-term HRQOL (SMD 0.03, 95% CI -0.19 to 0.24; participants = 323; studies = 2), medium-term GORD-specific QoL (SMD 0.28, 95% CI -0.27 to 0.84; participants = 994; studies = 3), proportion of people with adverse events (surgery: 7/43 (adjusted proportion = 14.0%); medical: 0/40 (0.0%); RR 13.98, 95% CI 0.82 to 237.07; participants = 83; studies = 1), long-term dysphagia (surgery: 27/118 (adjusted proportion = 22.9%); medical: 28/110 (25.5%); RR 0.90, 95% CI 0.57 to 1.42; participants = 228; studies = 1), and long-term reflux symptoms (surgery: 29/118 (adjusted proportion = 24.6%); medical: 41/115 (35.7%); RR 0.69, 95% CI 0.46 to 1.03; participants = 233; studies = 1).The short-term GORD-specific QoL was better in the laparoscopic fundoplication group than in the medical treatment group (SMD 0.58, 95% CI 0.46 to 0.70; participants = 1160; studies = 4).The proportion of people with serious adverse events (surgery: 60/331 (adjusted proportion = 18.1%); medical: 38/306 (12.4%); RR 1.46, 95% CI 1.01 to 2.11; participants = 637; studies = 2), short-term dysphagia (surgery: 44/331 (adjusted proportion = 12.9%); medical: 11/306 (3.6%); RR 3.58, 95% CI 1.91 to 6.71; participants = 637; studies = 2), and medium-term dysphagia (surgery: 29/288 (adjusted proportion = 10.2%); medical: 5/266 (1.9%); RR 5.36, 95% CI 2.1 to 13.64; participants = 554; studies = 1) was higher in the laparoscopic fundoplication group than in the medical treatment group.The proportion of people with heartburn at short term (surgery: 29/288 (adjusted proportion = 10.0%); medical: 59/266 (22.2%); RR 0.45, 95% CI 0.30 to 0.69; participants = 554; studies = 1), medium term (surgery: 12/288 (adjusted proportion = 4.2%); medical: 59/266 (22.2%); RR 0.19, 95% CI 0.10 to 0.34; participants = 554; studies = 1), long term (surgery: 46/111 (adjusted proportion = 41.2%); medical: 78/106 (73.6%); RR 0.56, 95% CI 0.44 to 0.72); participants = 217; studies = 1) and those with reflux symptoms at short-term (surgery: 6/288 (adjusted proportion = 2.0%); medical: 53/266 (19.9%); RR 0.10, 95% CI 0.05 to 0.24; participants = 554; studies = 1) and medium term (surgery: 6/288 (adjusted proportion = 2.1%); medical: 37/266 (13.9%); RR 0.15, 95% CI 0.06 to 0.35; participants = 554; studies = 1) was less in the laparoscopic fundoplication group than in the medical treatment group. There is considerable uncertainty in the balance of benefits versus harms of laparoscopic fundoplication compared to long-term medical treatment with proton pump inhibitors. Further RCTs of laparoscopic fundoplication versus medical management in patients with GORD should be conducted with outcome-assessor blinding and should include all participants in the analysis. Such trials should include long-term patient-orientated outcomes such as treatment-related adverse events (including severity), quality of life, and also report on the social and economic impact of the adverse events and symptoms.

Anorexia nervosa (AN), a severe mental disorder with an onset during adolescence, has been found to be difficult to treat. Identifying variables that predict long-term outcome may help to develop better treatment strategies. Since body image distortion and weight gain are central elements of diagnosis and treatment of AN, the current study investigated perceptual body image distortion, defined as the accuracy of evaluating one's own perceived body size in relation to the actual body size, as well as total and early weight gain during inpatient treatment as predictors for long-term outcome in a sample of 76 female adolescent AN patients. Long-term outcome was defined by physical, psychological and psychosocial adjustment using the Morgan-Russell outcome assessment schedule as well as by the mere physical outcome consisting of menses and/or BMI approximately 3 years after treatment. Perceptual body image distortion and early weight gain predicted long-term outcome (explained variance 13.3 %), but not the physical outcome alone. This study provides first evidence for an association of perceptual body image distortion with long-term outcome of adolescent anorexia nervosa and underlines the importance of sufficient early weight gain.

The objectives were twofold: (a) examine long-term treatment effects in youth receiving 1-session treatment (OST) or educational support (EST) for a specific phobia (SP) and (b) examine the differential predictive and moderation effects of attention-deficit/hyperactivity disorder (ADHD) symptoms on immediate and long-term outcomes following the interventions. Eighty-three children (ages 6-15, 47% female, 89% White) with a SP were randomly assigned to receive OST or EST. Follow up assessments occurred at 1 week, 6 months, 1 year, and 4 years. Hierarchical linear growth modeling (HLGM) was used to explore the association of parent-reported ADHD symptoms, the 2 treatment conditions (i.e., OST vs. EST), and the trajectory of change in the severity of the SP from pretreatment to the 4-year follow-up. Age, conduct problems and learning problems were controlled for in all analyses. A greater immediate reduction in severity rating of the SP was observed in the OST compared to EST, whereas the trajectory of long-term outcomes was similar across conditions over time. Higher levels of ADHD symptoms predicted poor immediate and long-term treatment outcomes across treatment conditions. ADHD symptoms, however, did not moderate the relationship between treatment condition and immediate or long-term treatment outcomes. The results of the study need to be interpreted in light of several study limitations. However, if confirmed, the findings suggest that anxious youth with comorbid ADHD symptoms are less likely to benefit from brief, intensive psychotherapy and may require either longer, standard CBT treatment or adjunctive pharmacotherapy.

Long-term treatment of deep-vein thrombosis with low-molecular-weight heparin: an update of the evidence.

PubMed

Hull, Russell D; Townshend, Grace

2013-07-01

This article reviews updated evidence-based knowledge on long-term treatment of deep-vein thrombosis (DVT) with low-molecular-weight heparin (LMWH) or vitamin K antagonists (VKAs). Eleven trials were identified comparing the two treatments in a broad spectrum of patients with DVT and with >100 study participants. Four comparative trials were identified in patients with cancer and DVT (in whom anticoagulation treatment is more complex and bleeding complications more frequent). In the 11 trials in broad patient populations, LMWHs were as effective as VKAs in preventing recurrent venous thromboembolism (VTE), and there were no consistent differences in the incidence of bleeding complications during long-term treatment. In patients with cancer, VTE recurrence was significantly reduced with LMWH versus VKA in two studies, while major bleeding complications did not differ between groups in any of the four trials. Current evidence-based European and American guidelines recommend LMWH over VKA for the long-term treatment of DVT in patients with cancer. LMWH and VKA are recommended over the new oral anticoagulant drugs, for which there are limited data on use in long-term treatment. Post-thrombotic syndrome (PTS), a common complication of DVT, causes considerable morbidity. Long-term use of tinzaparin reduced the risk of PTS compared with VKA in one trial, and a meta-analysis of nine studies in total demonstrated a consistently favourable effect of LMWHs versus VKA on PTS-related outcomes. Given the limited treatment options available for PTS, this suggests that LMWHs provide a useful therapeutic option in any patient particularly at risk of developing PTS.

To design and establish a uterine fibroid (UF) registry based in the United States (US) to provide comparative effectiveness data regarding UF treatment. We report here the design and initial recruitment for the Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) registry (Clinicaltrials.gov, NCT02260752), funded by the Agency for Healthcare Research and Quality (AHRQ) in collaboration with the-Patient-Centered Outcomes Research Institute (PCORI). COMPARE-UF is designed to help answer critical questions about treatment options for women with symptomatic UF. Women undergoing a procedure for UF (hysterectomy, myomectomy [abdominal, hysteroscopic, vaginal and laparoscopic/robotic], endometrial ablation, radiofrequency fibroid ablation, uterine artery embolization, magnetic resonance guided focused ultrasound or progestin-releasing intrauterine device insertion) at one of the COMPARE-UF sites are invited to participate in a prospective registry with three years follow-up for post-procedural outcomes. Enrolled participants provide annual follow-up through an online portal or through traditional phone contact. A central data abstraction center provides information obtained from imaging, operative or procedural notes and pathology reports. Women with uterine fibroids and other stakeholders are a key part of the COMPARE-UF registry and participate at all points from study design to dissemination of results. We built a network of nine clinical sites across the US with expertise in the care of women with UF to capture geographic, racial, ethnic and procedural diversity. Of the initial 2031 women enrolled in COMPARE-UF, 42% are self-identified as Black or African-American and 40% are age 40 years or younger with 16% of participants under age 35. Women undergoing myomectomy comprise the largest treatment group at 46% of all procedures with laparoscopic or robotic myomectomy comprising the largest subset of myomectomies at 19% of all procedures. Hysterectomy is the second most common treatment within the registry at 38%. In response to priorities identified by our patient stakeholders, the initial aims within COMPARE-UF will address how different procedures used to treat UF compare in terms of long-lasting symptom relief, potential for recurrence, medical complications, improvement in quality of life and sexual function, age at menopause, and fertility and pregnancy outcomes. COMPARE-UF will generate evidence on the comparative effectiveness of different procedural options for UF, in order to help patients and their caregivers make informed decisions that best meet an individual patient's short- and long-term preferences. Building upon this infrastructure, the COMPARE-UF team of investigators and stakeholders, including patients, collaborate to identify future priorities for expanding the registry, such assessing the efficacy of medical therapies for UF. COMPARE-UF results will be disseminated directly to patients, providers, and other stakeholders using traditional academic pathways, as well as innovative methods, including a variety of social media platforms. Given demographic differences among women undergoing different UF treatments, assessing comparative effectiveness for this disease through clinical trials will remain difficult. Therefore, this registry provides optimized evidence to help patients and their providers better understand the pros and cons of different treatment options so that they can make more informed decisions.

Standard myeloablative conditioning regimens for children with acute lymphoblastic leukaemia are based on total body irradiation (TBI). However, TBI causes profound short-term and long-term side effects, provoking the necessity for alternative regimens. Treosulfan combines a potent immunosuppressive and antileukaemic effect with myeloablative activity and low toxicity profile. We retrospectively studied toxicity and outcome of 71 paediatric patients with acute lymphoblastic leukaemia (ALL) undergoing haematopoietic stem cell transplantation (HSCT) following treosulfan-based conditioning aiming to identify risk factors for treatment failure and dose-depending outcome differences. Early regimen-related toxicity was low. No case of veno-occlusive disease was reported. There was no association of toxicity with age or number of HSCT. Event-free survival (EFS) of infants was significantly better compared to older children. Overall survival (OS) at 3 years was 51 % and not significantly influenced by number of HSCT (first HSCT 54 %, ≥second HSCT 44 %, p = 0.71). In multivariate analysis, OS and EFS were significantly worse for patients transplanted without complete remission (p = 0.04 and 0.004). Treatment-related mortality was low at 14 %. We conclude that treosulfan-based conditioning is a safe and efficacious approach for paediatric ALL.

Although the influence of QRS duration (QRSd) and/or bundle branch block morphology on outcomes of cardiac resynchronization therapy (CRT) have been well studied, the effect of PR interval remains uncertain. The purpose of this study was to evaluate the impact of PR prolongation (PRp) before CRT on long-term outcomes, specifically taking into account bundle branch block morphology and QRSd. We extracted clinical data on consecutive patients undergoing CRT. Multivariate models were constructed to analyze the effect of PRp (≥200 ms) on the combined endpoint of death, heart transplant, or left ventricular assist device. Kaplan-Meier curves were constructed stratifying patients based on bundle branch block and QRSd (dichotomized by 150 ms). Of the 472 patients who met inclusion criteria, 197 (41.7%) had PR interval ≥200 ms. During follow-up (mean 5.1 ± 2.6 years) there were 214 endpoints, of which 109 (23.1%) occurred in patients with PRp. In multivariate analysis, PRp was independently associated with worsened outcomes (hazard ratio 1.34, 95% confidence interval 1.01-1.77, P = .04). When stratified by bundle branch block morphology, PRp was significantly associated with worsened outcomes (log-rank P <.001) in patients with LBBB but not in those with non-LBBB (log-rank P = .55). Among patients with LBBB, stratified by QRSd, patients without PRp had improved outcomes compared to those with PRp independent of QRSd (log-rank P <.001). PRp is an independent predictor of impaired long-term outcome after CRT among patients with LBBB but not in non-LBBB patients. Notably, among LBBB patients, PRp is a more important predictor than QRSd in assessing long-term outcomes. Copyright © 2017. Published by Elsevier Inc.

It is not known whether the extent and severity of non-culprit coronary lesions correlate with outcomes in patients with STEMI referred for primary PCI. We sought to quantify complex plaques in ST-segment elevation myocardial infarction (STEMI) patients referred for primary percutaneous coronary intervention (PCI) and to determine their effect on short- and long-term clinical outcomes by examining the core laboratory database for plaque analysis from the HORIZONS-AMI study. Baseline demographic, angiographic, and procedural details were compared between patients with single vs. multiple complex plaques undergoing single vessel PCI. Multivariable analysis was performed for predictors of long-term major adverse cardiac events (MACE), a combined end point of death, reinfarction, ischemic target vessel revascularization, or stroke, and for death alone. Single vessel PCI was performed in 3,137 patients (87%): 2,174 (69%) had multiple complex plaques and 963 (31%) had a single complex plaque. Compared to those with a single complex plaque, patients with multiple complex plaques were older (p<0.0001) and had more comorbidities. The presence of multiple complex plaques was an independent predictor of 3-year MACE (hazard ratio [HR]: 1.58; 95% confidence interval [CI]: 1.26–1.98, p<0.0001), and death alone (HR: 1.68; 95% CI: 1.05–2.70, p=0.03). In conclusion, multiple complex plaques are present in the majority of STEMI patients undergoing primary PCI and their presence is an independent predictor of short- and long-term MACE, including death.

Fewer men than women with severe obesity undergo bariatric surgery for weight loss, and knowledge about men's situation after surgery, beyond medical status, is lacking. Our aim was to explore men's experiences with life after bariatric surgery from a long-term perspective. We conducted in-depth interviews with 13 men, aged 28–60 years, between 5 and 7 years after surgery. The analysis was inspired by Giorgi's phenomenological method. We found that agency was pivotal for how the men understood themselves and their lives after surgery. Weight loss meant regaining opportunities for living and acting in unrestricted and independent daily lives, yet surgery remained a radical treatment with complex consequences. Turning to surgery had involved conceptualizing their own body size as illness, which the men had resisted doing for years. After surgery, the rapid and major weight loss and the feelings of being exhausted, weak, and helpless were intertwined. The profound intensity of the weight loss process took the men by surprise. Embodying weight loss and change involved an inevitable renegotiating of experiences connected to the large body. Having bariatric surgery was a long-term process that seemed unfinished 5 years after surgery. Restrictions and insecurity connected to health and illness persist, despite successful weight loss and embodied change. Bariatric surgery initiated a complex and long-lasting life-changing process, involving both increased capacity for agency and illness-like experiences. PMID:26066518

This study aims to explore the influence on soil physicochemical properties under a 38-y long-term fertilization in a brown soil. Soil samples (0-20 cm)were taken from the six treatments of the long-term fertilization trial in October 2016:no fertilizer (CK), N1(mineral nitrogen fertilizer), N1P (mineral nitrogen and phosphate fertilizer), N1PK (mineral nitrogen, phosphate and potassic fertilizer), pig manure (M2), M2N1P (pig manure, mineral nitrogen and phosphate fertilizer).The results showed thatthe long-term application of chemical fertilizers reduced soil pH value, while the application of organic fertilizers increased pH value. Fertilization significantly increased the content of AHN, TN and SOM. Compared with the CK treatment and chemical fertilizer treatments, organic fertilizer treatments significantly increased the content of AP and TP. The content of AK and TK were no significant difference in different treatment.

Many patients with cancer take antioxidant nutritional supplements during cancer treatment to alleviate treatment toxicities and to improve long-term outcomes, but little is known about the efficacy and safety of antioxidant use during cancer treatment. We reviewed English-language manuscripts published in the biomedical literature, reporting the results of observational studies of antioxidant status and cancer outcomes and of intervention trials of antioxidants among patients receiving chemotherapy with or without radiation for various malignancies. We searched the Medline database and the bibliographies of the retrieved manuscripts, reviews, and books on antioxidants and cancer. The retrieved studies are grouped by study design, malignancy, and end points. More than 100 citations were retrieved; 52 met our criteria, 31 were observational studies, and 21 were intervention trials. The studies varied in study design, timing of observation/intervention, intervention protocol, malignancy, and anticancer regimen. These inconsistencies preclude a definitive conclusion as to the effect of chemotherapy on antioxidant status in patients undergoing anticancer therapy. However, our review suggests that total antioxidant status (measured by total radical antioxidant parameter) declines during cancer treatment. Adequately powered trials or observational studies among patients with a specific cancer diagnosis receiving a specific treatment regimen are needed to address patients' and physicians' concerns regarding these associations.

As management of multiple sclerosis (MS) requires life-long treatment with disease-modifying agents, any risks associated with long-term use should be considered when evaluating therapeutic options. Immune cells of the innate and adaptive immune systems play various roles in the pathogenesis of MS. MS therapies affect the immune system, each with a unique mode of action, and consequently possess different long-term safety profiles. Rare, but serious safety concerns, including an increased risk of infection and cancer, have been associated with immunosuppressant use. The risks associated with newer immunosuppressive agents, which target specific elements of MS disease pathophysiology, are not yet fully established as the duration of clinical trials is relatively short and post-marketing experience is limited. Non-immunosuppressants used to treat MS have well-defined safety profiles established over a large number of patient-years demonstrating them to be well-tolerated long-term treatment options. When considering the long-term use of disease-modifying agents for treating MS, classification as immunosuppressants or non-immunosuppressants can be useful when evaluating potential risks associated with chronic use. A successful therapeutic strategy for any serious, chronic disease such as MS should weigh effectiveness versus long-term safety of available treatments.

Rheumatologic disorders are characterised by inflammation and an increased risk of coronary artery disease (CAD). However, the association between rheumatologic disorders and long-term prognosis in CAD patients undergoing percutaneous coronary intervention (PCI) is unknown. Thus, we aimed to examine the association between rheumatologic disorders and long-term prognosis in CAD patients undergoing PCI. A post-hoc analysis was performed in 4605 patients (age: 63.3 ± 11.0 years; male: 76.6%) with ST-segment elevation myocardial infarction (STEMI; n = 1396), non-STEMI ( n = 1541), and stable CAD ( n = 1668) from the all-comer stent trials, the BAsel Stent Kosten-Effektivitäts Trial-PROspective Validation Examination (BASKET-PROVE) I and II trials. We evaluated the association between rheumatologic disorders and 2-year major adverse cardiac events (MACEs; cardiac death, nonfatal myocardial infarction (MI), and target vessel revascularisation (TVR)) by Cox regression analysis. Patients with rheumatologic disorders ( n = 197) were older, more often female, had a higher prevalence of renal disease, multi-vessel coronary disease, and bifurcation lesions, and had longer total stent lengths. During the 2-year follow-up, the MACE rate was 8.6% in the total cohort. After adjustment for potential confounders, rheumatologic disorders were associated with MACEs in the total cohort (adjusted hazard ratio: 1.55; 95% confidence interval (CI): 1.04-2.31) driven by the STEMI subgroup (adjusted hazard ratio: 2.38; 95% CI: 1.26-4.51). In all patients, rheumatologic disorders were associated with all-cause death (adjusted hazard ratio: 2.05; 95% CI: 1.14-3.70), cardiac death (adjusted hazard ratio: 2.63; 95% CI: 1.27-5.43), and non-fatal MI (adjusted hazard ratio: 2.64; 95% CI: 1.36-5.13), but not with TVR (adjusted hazard ratio: 0.81; 95% CI: 0.41-1.58). The presence of rheumatologic disorders appears to be independently associated with worse outcome in CAD patients undergoing PCI. This calls for further studies and focus on this high-risk group of patients following PCI.

To describe latent tuberculosis infection (LTBI) testing practices in long-term care facilities (LTCFs). Retrospective cohort study. Three Boston-area LTCFs. Residents admitted between January 1 and December 31, 2011. Resident demographic characteristics, comorbidities, LTCF stay, and LTBI testing and treatment. Data for 291 LTCF residents admitted in 2011 were reviewed. Of the 257 without a history of LTBI and with documentation of testing, 162 (63%) were tested; 114 of 186 (61%) with a stay less than 90 days and 48 of 71 (68%) with a stay of 90 days or longer were tested. Of 196 residents with data on prior LTBI testing, 39 (19.9%) had LTBI; 12 of these (30.8%) were diagnosed at the LTCF. Hispanic participants were more likely than black participants to undergo LTBI testing (adjusted odds ratio (aOR) = 2.4, P = .003). Having a length of stay of less than 90 days (aOR = 0.7, P < .001) and history of illicit drug use (aOR = 0.7, P < .001) were associated with lower odds of LTBI testing. One-fifth of LTCF residents had LTBI, but testing was not always performed. The high prevalence of LTBI in older adults combined with the risk of an outbreak if a case of tuberculosis occurs in a LTCF make LTBI testing and treatment an important prevention opportunity. The importance of LTBI testing in LTCFs needs to be reinforced. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Drug-eluting stents (DES) reduce restenosis rates compared to bare-metal stents. Most trials using DES enrolled selected patient and lesion subtypes, and primary endpoint focused on angiographic metrics or relatively short-term outcomes. When DES are used in broader types of lesions and patients, important differences may emerge in long-term outcomes between stent types, particularly the incidence of late stent thrombosis. PROTECT is a randomized, open-label trial comparing the long-term safety of the zotarolimus-eluting stent and the sirolimus-eluting stent. The trial has enrolled 8,800 patients representative of those seen in routine clinical practice, undergoing elective, unplanned, or emergency procedures in native coronary arteries in 196 centers in 36 countries. Indications for the procedure and selection of target vessel and lesion characteristics were at the operator's discretion. Procedures could be staged, but no more than 4 target lesions could be treated per patient. Duration of dual antiplatelet therapy was prespecified to achieve similar lengths of treatment in both study arms. The shortest predefined duration was 3 months, as per the manufacturer's instructions. The primary outcome measure is the composite rate of definite and probable stent thrombosis at 3 years, centrally adjudicated using Academic Research Consortium definitions. The main secondary end points are 3-year all-cause mortality, cardiac death, large nonfatal myocardial infarction, and all myocardial infarctions. This large, international, randomized, controlled trial will provide important information on comparative rates of stent thrombosis between 2 different DES systems and safety as assessed by patient-relevant long-term clinical outcomes.

OBJECTIVE Apraxia is a cognitive-motor deficit affecting the execution of skilled movements, termed praxis gestures, in the absence of primary sensory or motor disorders. In patients affected by stroke, apraxia is associated with lesions of the lateral parietofrontal stream, connecting the posterior parietal areas with the ventrolateral premotor area and subserving sensory-motor integration for the hand movements. In the neurosurgical literature to date, there are few reports regarding the incidence of apraxia after glioma surgery. A retrospective analysis of patients who harbored a glioma around the central sulcus and close to the parietofrontal circuits in depth showed a high incidence of long-term postoperative hand apraxia, impairing the patients' quality of life. To avoid the occurrence of postoperative apraxia, the authors sought to develop an innovative intraoperative hand manipulation task (HMt) that can be used in association with the brain mapping technique to identify and preserve the cortical and subcortical structures belonging to the praxis network. METHODS The intraoperative efficacy of the HMt was investigated by comparing the incidence of postoperative ideomotor apraxia between patients undergoing mapping with (n = 79) and without (n = 41) the HMt. Patient groups were balanced for all demographic and clinical features. RESULTS In patients with lesions in the dominant hemisphere, the HMt dramatically reduced the incidence of apraxia, with a higher sensitivity for the ideomotor than for the constructional abilities; patients with lesions in the nondominant hemisphere benefitted from the HMt for both ideomotor and constructional abilities. The administration of the test did not reduce the extent of resection. CONCLUSIONS The HMt is a safe and feasible intraoperative tool that allowed surgeons to prevent the occurrence of long-term hand apraxia while attaining resection goals for the surgical treatment of glioma.

Background Intra-aortic balloon pumps (IABP) have generally been used for patients undergoing high-risk mechanical coronary revascularization. However, there is still insufficient evidence to determine whether they can improve outcomes in reperfusion therapy patients, mainly by percutaneous coronary intervention (PCI) with stenting or coronary artery bypass graft (CABG). This study was designed to determine the difference between high-risk mechanical coronary revascularization with and without IABPs on mortality, by performing a meta-analysis on randomized controlled trials of the current era. Methods Pubmed and Embase databases were searched from inception to May 2015. Unpublished data were obtained from the investigators. Randomized clinical trials of IABP and non-IABP in high-risk coronary revascularization procedures (PCI or CABG) were included. In the case of PCI procedures, stents should be used in more than 80% of patients. Numbers of events at the short-term and long-term follow-up were extracted. Results A total of 12 randomized trials enrolling 2155 patients were included. IABPs did not significantly decrease short-term mortality (relative risk (RR) 0.66; 95% CI, 0.42–1.01), or long-term mortality (RR 0.79; 95% CI, 0.47–1.35), with low heterogeneity across the studies. The findings remained stable in patients with acute myocardial infarction with or without cardiogenic shock. But in high-risk CABG patients, IABP was associated with reduced mortality (71 events in 846 patients; RR 0.40; 95%CI 0.25–0.67). Conclusion In patients undergoing high-risk coronary revascularization, IABP did not significantly decrease mortality. But high-risk CABG patients may be benefit from IABP. Rigorous criteria should be applied to the use of IABPs. PMID:26784578

Background/Aim: Studies comparing health-related quality of life (HR-QoL) between patients who underwent radical cystectomy (RC) and those who underwent a different form of urinary diversion has not reached yet univocal and reliable conclusions. The aim of our study was to evaluate bladder-specific long-term HR-QoL after radical cystectomy and ileal conduit. Patients and Methods: A multicenter study was carried out on 145 consecutive patients (112 males and 33 females) undergoing RC and ileal conduit (IC). HR-QoL assessment was conducted using Italian versions of European Organisation for Research and Treatment of Cancer QLQ-C30 and EORTC BLM-30 questionnaires. Results: Our data showed that women who underwent IC presented greater problems than men in cognitive functioning (mean score±SD: 77.3±27.9 vs. 87.8±18.6) as well in future perspective (score: 42.4±34.4 vs. 21.9±24.6). Nevertheless, men undergoing IC had more problems in sexual functioning than women (score: 23.3±24.5 vs. 7.0±20.3) (all p<0.05). Conclusion: In our series, female patients presented a greater burden than male patients in cognitive functioning as well in future perspective, but lower concerns with regard to sexual function.

The protective effects of 17-beta estradiol (E2) on cardiac tissue during ischemia/reperfusion (I/R) injury have not yet been fully elucidated. To assess the protective effects of short- and long-term E2 treatments on cardiac tissue exposed to I/R, and to assess the effects of these treatments in combination with ischemic preconditioning (IPC) on cardiac protection from I/R injury. SPRAGUE DAWLEY RATS WERE ASSIGNED TO THE FOLLOWING TREATMENT PROTOCOLS: control (no preconditioning); IPC (isolated hearts were subjected to two cycles of 5 min global ischemia followed by 10 min of reperfusion); E2 preconditioning (E2PC; isolated hearts were subjected to E2 pharmacological perfusion for 15 min); short-term in vivo E2 pretreatment for 3 h; long-term in vivo E2 pretreatment or withdrawal (ovariectomy followed by a six-week treatment with E2 or a placebo); combined IPC and E2PC; combined IPC and short- or long-term E2 pretreatments or withdrawal. All hearts were isolated and stabilized for at least 30 min before being subjected to 40 min of global ischemia followed by 30 min of reperfusion; left ventricular function and vascular hemodynamics were then assessed. IPC, E2PC and short-term E2 pretreatment led to the recovery of left ventricle function and vascular hemodynamics. Long-term E2 and placebo treatments did not result in any protection compared with untreated controls. The combination of E2PC or short-term E2 treatments with IPC did not block the IPC protection or result in any additional protection to the heart. Long-term E2 treatment blocked IPC protection; however, placebo treatment did not. Short-term treatment with E2 protected the heart against I/R injury through a pathway involving the regulation of tumour necrosis factor-alpha. The combination of short-term E2 treatment with IPC did not provide additional protection to the heart. Short-term E2 treatment may be a suitable alternative for classical estrogen replacement therapy.

Fibromyalgia, a chronic syndrome of diffuse musculoskeletal pain and somatic hyperalgesia from central sensitization, is very often comorbid with visceral pain conditions. In fibromyalgia patients with gallbladder calculosis, this study assessed the short and long-term impact of laparoscopic cholecystectomy on fibromyalgia pain symptoms. Fibromyalgia pain (VAS scale) and pain thresholds in tender points and control areas (skin, subcutis and muscle) were evaluated 1week before (basis) and 1week, 1,3,6 and 12months after laparoscopic cholecystectomy in fibromyalgia patients with symptomatic calculosis (n = 31) vs calculosis patients without fibromyalgia (n. 26) and at comparable time points in fibromyalgia patients not undergoing cholecystectomy, with symptomatic (n = 27) and asymptomatic (n = 28) calculosis, and no calculosis (n = 30). At basis, fibromyalgia+symptomatic calculosis patients presented a significant linear correlation between the number of previously experienced biliary colics and fibromyalgia pain (direct) and muscle thresholds (inverse)(p<0.0001). After cholecystectomy, fibromyalgia pain significantly increased and all thresholds significantly decreased at 1week and 1month (1-way ANOVA, p<0.01-p<0.001), the decrease in muscle thresholds correlating linearly with the peak postoperative pain at surgery site (p<0.003-p<0.0001). Fibromyalgia pain and thresholds returned to preoperative values at 3months, then pain significantly decreased and thresholds significantly increased at 6 and 12months (p<0.05-p<0.0001). Over the same 12-month period: in non-fibromyalgia patients undergoing cholecystectomy thresholds did not change; in all other fibromyalgia groups not undergoing cholecystectomy fibromyalgia pain and thresholds remained stable, except in fibromyalgia+symptomatic calculosis at 12months when pain significantly increased and muscle thresholds significantly decreased (p<0.05-p<0.0001). The results of the study show that biliary colics from gallbladder calculosis represent an exacerbating factor for fibromyalgia symptoms and that laparoscopic cholecystectomy produces only a transitory worsening of these symptoms, largely compensated by the long-term improvement/desensitization due to gallbladder removal. This study provides new insights into the role of visceral pain comorbidities and the effects of their treatment on fibromyalgia pain/hypersensitivity. PMID:27081848

In symptomatic unruptured intracranial aneurysms (UIAs), data on long-term functional outcome are sparse in the literature, even in the light of modern interdisciplinary treatment decisions. We therefore analyzed our in-house database for prognostic factors and long-term outcome of neurologic symptoms after microsurgical/endovascular treatment. Patients treated between 2000 and 2016 after interdisciplinary vascular board decision were included. UIAs were categorized as symptomatic in cases of cranial nerve or brainstem compression. Symptoms were categorized as mild/severe. Long-term development of symptoms after treatment was assessed in a standardized and independent fashion. Of 98 symptomatic UIAs (microsurgery/endovascular 43/55), 84 patients presented with cranial nerve (NII-VI) compression and 14 patients with brainstem compression symptoms. Permanent morbidity occurred in 9% of patients. Of 119 symptoms (mild/severe 71/48), 60.4% recovered (full/partial 22%/39%) and 29% stabilized by the time of last follow-up; median follow-up was 19.5 months. Symptom recovery was higher in the long-term compared with that at discharge (P = 0.002). Optic nerve compression symptoms were less likely to improve compared with abducens nerve palsies and brainstem compression. Prognostic factors for recovery were duration and severity of symptoms, treatment modality (microsurgery) and absence of ischemia in the multivariate analysis. This recent study presents for the first time a detailed analysis of relevant prognostic factors for long-term recovery of cranial nerve/brainstem compression symptoms in an interdisciplinary treatment concept, which was excellent in most patients, with lowest recovery rates in optic nerve compression. Symptom recovery was remarkably higher in the long-term compared with recovery at discharge. Copyright © 2017 Elsevier Inc. All rights reserved.

Thirty-day unplanned hospital readmission in ovarian cancer patients undergoing primary or interval cytoreductive surgery: systematic literature review.

Clark, Rachel M; Rice, Laurel W; Del Carmen, Marcela G

2018-06-18

Thirty-day readmission rate has been proposed as metric of quality and remains an ongoing clinical concern in the primary treatment of patients with advanced-stage ovarian epithelial ovarian cancer. We conducted a review of the literature to identify rates, risk factors, and predictors for 30-day readmission in this population. A 10-year period MEDLINE (PubMed) search of English literature studies published between January 01, 2008-January 01, 2018 was performed to identify appropriate studies for review. Thirty -day readmission rates for ovarian cancer patients undergoing primary treatment ranged from 2.5-19.3%. Neoadjuvant chemotherapy and interval cytoreductive surgery (NACT-ICS) surgery was associated with lower readmission rates, when compared to primary debulking surgery (PDS). The most frequently reported adverse events resulting in readmission include inpatient management of ileus/small bowel obstruction, wound-related complications, and thromboembolic events. Readmission predictors included the presence of other medical comorbidities, re-operation, and major complications occurring after initial hospital discharge. Some studies reported lower rates of readmission and survival in patients treated by NACT-ICS. Policies and programs should be designed to measure short- and long-term outcomes in this patient population to avoid bias in assigning patients to NACT-ICS to maintain low 30-day readmission rates.

To describe the outcome of cranial closing wedge osteotomy (CWO) of the tibia for treatment of cranial cruciate ligament (CrCL)-deficient stifles in dogs with a body weight of <15 kg. Retrospective case series. Forty-five client-owned dogs (n=55 stifles). Medical records (2005-2014), radiographs, and owner questionnaire were used to identify the surgical procedure performed, associated complications and outcome in 45 dogs undergoing CWO in 55 stifles. Data for 55 stifles from 45 dogs were included. Bichon Frise was the most frequent dog breed (n=11). Mean pre- and postoperative tibial plateau angle (TPA) were 36.3° (95% CI 35.1-37.5) and 7.5° (95% CI 6.7-8.2), respectively. Pin and tension bands were placed in 38/55 stifles (69%). The most frequent complication at short-term follow-up (2 weeks) was incisional complications in 8 stifles; all resolved with systemic antibiotic administration alone. Data were available for all stifles at 8 week follow-up with an overall complication occurrence in 16/55 stifles (28%); 1 dog required revision surgery. Tibial osteotomy healing was evident on radiographs at 8 weeks postoperative in 53 stifles (96%), considered complete in 27 stifles, and good in 26 stifles. Follow-up owner questionnaire was available for 36 dogs at a mean of 24 months and 34/36 owners (94%) were satisfied with the procedure and considered their dog had a good quality of life with minimal long-term complications. Dogs with a body weight <15 kg undergoing CWO for treatment of a CrCL-deficient stifle had a good outcome based on clinical status, radiographic evaluation, and owner questionnaire. © Copyright 2016 by The American College of Veterinary Surgeons.

Best long-term practice in primary HIV-1 infection (PHI) remains unknown for the individual. A risk-based scoring system associated with surrogate markers of HIV-1 disease progression could be helpful to stratify patients with PHI at highest risk for HIV-1 disease progression. We prospectively enrolled 290 individuals with well-documented PHI in the Zurich Primary HIV-1 Infection Study, an open-label, non-randomized, observational, single-center study. Patients could choose to undergo early antiretroviral treatment (eART) and stop it after one year of undetectable viremia, to go on with treatment indefinitely, or to defer treatment. For each patient we calculated an a priori defined "Acute Retroviral Syndrome Severity Score" (ARSSS), consisting of clinical and basic laboratory variables, ranging from zero to ten points. We used linear regression models to assess the association between ARSSS and log baseline viral load (VL), baseline CD4+ cell count, and log viral setpoint (sVL) (i.e. VL measured ≥90 days after infection or treatment interruption). Mean ARSSS was 2.89. CD4+ cell count at baseline was negatively correlated with ARSSS (p = 0.03, n = 289), whereas HIV-RNA levels at baseline showed a strong positive correlation with ARSSS (p<0.001, n = 290). In the regression models, a 1-point increase in the score corresponded to a 0.10 log increase in baseline VL and a CD4+ cell count decline of 12/µl, respectively. In patients with PHI and not undergoing eART, higher ARSSS were significantly associated with higher sVL (p = 0.029, n = 64). In contrast, in patients undergoing eART with subsequent structured treatment interruption, no correlation was found between sVL and ARSSS (p = 0.28, n = 40). The ARSSS is a simple clinical score that correlates with the best-validated surrogate markers of HIV-1 disease progression. In regions where ART is not universally available and eART is not standard this score may help identifying patients who will profit the most from early antiretroviral therapy.

The management of complicated benign upper urinary tract occlusion is extremely challenging, especially in patients unable to undergo an open operative procedure. We report the long-term results of a permanent metallic stent for benign upper urinary tract occlusion. From October 1995 to December 1998, 13 patients (8 men and 5 women, with a mean age of 43 years) with benign upper tract occlusion have been treated by metallic stent implantation. All patients had a nephrostomy tube to relieve the obstruction and the average time of the nephrostomy tube stay was 27 months, ranging from 3 to 131 months. The average length of occlusion was 2.7 cm, ranging from 1 to 3.6 cm. Ultrasonography, urography, diuresis renography and urine culture were performed every 3 months after stent insertion. Ureteroscopy was done when needed. The mean follow-up was 92 months (12-132 months). Ureteral patency was achieved in six patients and assisted patency with a Double-J stent was achieved in three patients. In two patients the kidney had to be removed because of progressive malfunction and in two patients the metal stent had to be extracted with the Holmium: YAG laser, burning it down due to the uncontrollable pyonephrosis. In three patients the ipsilateral flank pain recurred. One of these patients experienced urine leakage due to the initial nephrostomy tract: a ureteroscopy revealed a complete hyperplastic urothelial response. Proximal stone formations were found in 2 patients and all were removed by percutaneous nephrolithotomy (PCNL). No stent migration or fragmentation was observed. The implantation of metal stent is a safe and effective treatment for benign upper urinary tract occlusion, and has satisfying long-term outcome in selected cases. A further investigation is needed for its impact on the urodynamics of upper urinary tract.

Pancreaticoduodenectomy and left-sided pancreatectomy are the surgical treatment standards for tumors of the pancreas. Surgeons, who are requested to treat patients with benign tumors, using standard oncological resections, face the challenge of sacrificing pancreatic and extra-pancreatic tissue. Tumor enucleation, pancreatic middle segment resection and local, duodenum-preserving pancreatic head resections are surgical procedures increasingly used as alternative treatment modalities compared to classical pancreatic resections. Use of local resection procedures for cystic neoplasms and neuro-endocrine tumors of the pancreas (panNETs) is associated with an improvement of procedure-related morbidity, when compared to classical Whipple OP (PD) and left-sided pancreatectomy (LP). The procedure-related advantages are a 90-day mortality below 1% and a low level of POPF B+C rates. Most importantly, the long-term benefits of the use of local surgical procedures are the preservation of the endocrine and exocrine pancreatic functions. PD performed for benign tumors on preoperative normo-glycemic patients is followed by the postoperative development of new onset of diabetes mellitus (NODM) in 4 to 24% of patients, measured by fasting blood glucose and/or oral/intravenous glucose tolerance test, according to the criteria of the international consensus guidelines. Persistence of new diabetes mellitus during the long-term follow-up after PD for benign tumors is observed in 14.5% of cases and after surgery for malignant tumors in 15.5%. Pancreatic exocrine insufficiency after PD is found in the long-term follow-up for benign tumors in 25% and for malignant tumors in 49%. Following LP, 14-31% of patients experience postoperatively NODM; many of the patients subsequently change to insulin-dependent diabetes mellitus (IDDM). The decision-making for cystic neoplasms and panNETs of the pancreas should be guided by the low surgical risk and the preservation of pancreatic metabolic functions when undergoing a limited, local, tissue-sparing procedure.

Smoking cessation treatments are effective in men and women. However, possible sex-related differences in the outcome of these treatments remain a controversial topic. This study evaluated whether there were differences between men and women in the success of smoking cessation treatment, including gender-tailored components, in the short and long term (> 1 year). A telephone survey was carried out between September 2008 and June 2009 in smokers attended in a Smoking Cessation Clinic. All patients who have successfully completed treatment (3 months) were surveyed by telephone to determine their long-term abstinence. Those who remained abstinent were requested to attend the Smoking Cessation Clinic for biochemical validation (expired CO ≤10 ppm). The probability of remaining abstinent in the long-term was calculated using a Kaplan-Meier survival analysis. The treatment success rate at 3-months was 41.3% (538/1302) with no differences by sex 89% (479/538) among those located in the telephonic follow-up study and 47.6% (256/479) were abstinent without differences by sex (p = .519); abstinence was validated with CO less than 10 ppm in 191 of the 256 (53.9% men and 46.1% women). In the survival analysis, the probability of men and women remaining abstinent in the long-term was not significant. There are no differences by sex in the outcome of smoking cessation treatment that included gender-tailored components in the short and long term (> 1 year).

Background Evaluation of treatments for attention-deficit/hyperactivity disorder (ADHD) previously focused on symptom control, but attention has shifted to functional outcomes. The effect of different ADHD treatment periods and modalities (pharmacological, non-pharmacological, and combination) on long-term outcomes needs to be more comprehensively understood. Methods A systematic search of 12 literature databases using Cochrane’s guidelines yielded 403 English-language peer-reviewed, primary studies reporting long-term outcomes (≥2 years). We evaluated relative effects of treatment modalities and durations and effect sizes of outcomes reported as statistically significantly improved with treatment. Results The highest proportion of improved outcomes was reported with combination treatment (83% of outcomes). Among significantly improved outcomes, the largest effect sizes were found for combination treatment. The greatest improvements were associated with academic, self-esteem, or social function outcomes. A majority of outcomes improved regardless of age of treatment initiation (60%–75%) or treatment duration (62%–72%). Studies with short treatment duration had shorter follow-up times (mean 3.2 years total study length) than those with longer treatment durations (mean 7.1 years total study length). Studies with follow-up times <3 years reported benefit with treatment for 93% of outcomes, whereas those with follow-up times ≥3 years reported treatment benefit for 57% of outcomes. Post-hoc analysis indicated that this result was related to the measurement of outcomes at longer periods (3.2 versus 0.4 years) after treatment cessation in studies with longer total study length. Conclusions While the majority of long-term outcomes of ADHD improve with all treatment modalities, the combination of pharmacological and non-pharmacological treatment was most consistently associated with improved long-term outcomes and large effect sizes. Older treatment initiation age or longer durations did not markedly affect proportion of improved outcomes reported, but measurement of outcomes long periods after treatment cessation may attenuate results.

Accumulating evidence suggests that the transcriptional activator CREB1 is important for serotonin (5-HT)-induced long-term facilitation (LTF) of the sensorimotor synapse in Aplysia. Moreover, creb1 is among the genes activated by CREB1, suggesting a role for this protein beyond the induction phase of LTF. The time course of the requirement for CREB1 synthesis in the consolidation of long-term facilitation was examined using RNA interference (RNAi) techniques in sensorimotor co-cultures. Injection of CREB1 small-interfering RNA (siRNA) immediately or 10 h after 5-HT treatment blocked LTF when measured at 24 h and 48 h after treatment. In contrast, CREB1 siRNA did not block LTF when injected 16 h after 5-HT treatment. These results demonstrate that creb1 expression must be sustained for a relatively long time in order to support the consolidation of LTF. In addition, LTF is also accompanied by a long-term increase in the excitability (LTE) of sensory neurons (SNs). Because LTE was observed in the isolated SN after 5-HT treatment, this long-term change was intrinsic to that element of the circuit. LTE was blocked when CREB1 siRNA was injected into isolated SNs immediately after 5-HT treatment. These data suggest that 5-HT-induced CREB1 synthesis is required for consolidation of both LTF and LTE. PMID:21543617

An analysis was made on the 16-year experimental data from the long term fertilization, experiment of maize on a yellow soil in Guizhou of Southwest China. Four treatments, i. e. , no fertilization (CK), chemical fertilization (165 kg N x hm(-2), 82.5 kg P2O5 x hm(-2), and 82.5 kg K2O x hm(-2), NPK), organic manure (30555 kg x hm(-2), M), and combined applicatioin of chemical fertilizers and organic manure (NPKM), were selected to analyze the variation trends of maize yield and fertilizer use efficiency on yellow soil under effects of different long term fertilization modes, aimed to provide references for evaluating and establishing long term fertilization mode and promote the sustainable development of crop production. Overall, the maize yield under long term fertilization had an increasing trend, with a large annual variation. Treatment NPKM had the best yield-increasing effect, with the maize yield increased by 4075.71 kg x hm(-2) and the increment being up to 139.2%. Long term fertilization increased the fertilizer utilization efficiency of maize. In treatment M, the nitrogen and phosphorus utilization rates were increased significantly by 35.4% and 18.8%, respectively. Treatment NPK had obvious effect in improving potassium utilization rate, with an increment of 20% and being far higher than that in treatments M (8.7%) and NPKM (9.2%). The results showed that long term fertilization, especially the combined application of chemical fertilizers and organic manure, was of great importance in increasing crop yield and fertilizer use efficiency.

2016-01-01

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology. Patients with lesions should undergo history and physical exam including digital rectal exam and standard anoscopy. High-resolution anoscopy can be considered as well, although it is of questionable time and cost–effectiveness. Nonoperative treatments include expectant surveillance and topical imiquimod or 5-fluorouracil. Operative therapies include wide local excision and targeted ablation with electrocautery, infrared coagulation, or cryotherapy. Recurrence rates remain high regardless of treatment delivered and surveillance is paramount, although optimal surveillance regimens have yet to be established. PMID:26929753

Lung abscess as a complication of bronchial thermoplasty.

Bronchial thermoplasty (BT) is an emerging treatment modality for patients with difficult to treat asthma. It has been shown to be beneficial for symptom control and improves quality of life and reduces frequency of hospitalization. Safety data from the two major trials of BT indicate that patients who undergo these procedures are most likely to experience adverse respiratory events in the first six weeks post treatment. Lung abscess has never been reported as a direct complication of BT. In this case; we report a lung abscess as an immediate complication of BT, which we believe may be the first case. We describe a forty three year old Caucasian female presented three days post-bronchial thermoplasty with left sided chest pain radiating to the back associated with shortness of breath, wheeze and dry cough. She had also started to feel hot and cold and generally unwell. It remains unclear why this patient developed a lung abscess so acutely post BT treatment. It is important that safety data continues to be collated and published as the procedure becomes more widely available with further long term follow-up in particular.

Cigarette smoking is one of the major risk factors in the development and further progression of tumorigenesis, including oral squamous cell carcinoma (OSCC). Recent studies suggest that interplay cancer stem-like cells (CSCs) and epithelial−mesenchymal transdifferentiation (EMT) properties are responsible for the tumor maintenance and metastasis in OSCC. The aim of the present study was to investigate the effects of long-term exposure with nicotine, a major component in cigarette, on CSCs and EMT characteristics. The possible reversal regulators were further explored in nicotine-induced CSCs and EMT properties in human oral epithelial (OE) cells. Long-term exposure with nicotine was demonstrated to up-regulatemore » ALDH1 population in normal gingival and primary OSCC OE cells dose-dependently. Moreover, long-term nicotine treatment was found to enhance the self-renewal sphere-forming ability and stemness gene signatures expression and EMT regulators in OE cells. The migration/cell invasiveness/anchorage independent growth and in vivo tumor growth by nude mice xenotransplantation assay was enhanced in long-term nicotine-stimulated OE cells. Knockdown of Snail in long-term nicotine-treated OE cells was found to reduce their CSCs properties. Therapeutic delivery of Si-Snail significantly blocked the xenograft tumorigenesis of long-term nicotine-treated OSCC cells and largely significantly improved the recipient survival. The present study demonstrated that the enrichment of CSCs coupled EMT property in oral epithelial cells induced by nicotine is critical for the development of OSCC tumorigenesis. Targeting Snail might offer a new strategy for the treatment of OSCC patients with smoking habit. -- Highlights: ► Sustained nicotine treatment induced CSCs properties of oral epithelial cells. ► Long-term nicotine treatment enhance EMT properties of oral epithelial cells. ► Long-term nicotine exposure increased tumorigenicity of oral epithelial cells. ► Si-Snail blocked xenograft tumorigenesis of long-term nicotine-treated OSCC cells.« less

Increasing evidence points to the harmful effects of long-term benzodiazepine treatment. Our objective was to study the incidence of, and predictors for, long-term use of benzodiazepines and Z-drugs in bipolar disorder. We conducted a population-based cohort study, using data from Swedish national registers. Swedish residents aged 18-75 years with a recorded diagnosis of bipolar disorder or mania between July 2006 and December 2012, and no history of benzodiazepine/Z-drug use in the past year, were included. Patients were followed for 1 year with regard to prescription fills of benzodiazepines/Z-drugs. Initiators were followed for another year during which continuous use for >6 months was defined as "long-term". Patient and prescription characteristics were investigated as potential predictors for long-term use in multivariate logistic regression models. Out of the 21 883 patients included, 29% started benzodiazepine/Z-drug treatment, of whom one in five became long-term users. Patients who were prescribed clonazepam or alprazolam had high odds for subsequent long-term use (adjusted odds ratios [aORs] 3.78 [95% confidence interval (CI) 2.24-6.38] and 2.03 [95% CI 1.30-3.18], respectively), compared to those prescribed diazepam. Polytherapy with benzodiazepines/Z-drugs also predicted long-term use (aOR 2.46, 95% CI 1.79-3.38), as did age ≥60 years (aOR 1.93, 95% CI 1.46-2.53, compared to age <30 years), and concomitant treatment with psychostimulants (aOR 1.78, 95% CI 1.33-2.39). The incidence of subsequent long-term use among bipolar benzodiazepine initiators is high. Patients on clonazepam, alprazolam or benzodiazepine/Z-drug polytherapy have the highest risk of becoming long-term users, suggesting that these treatments should be used restrictively. © 2018 John Wiley & Sons A/S.

To determine the long-term outcomes of patients with an isolated ovarian recurrence after fertility sparing surgery (FSS) for epithelial ovarian cancer (EOC) and to evaluate the recurrence rates (and location) according to the new 2014 International Federation of Gynecology and Obstetrics (FIGO) staging system. Retrospective multicenter study. Teams having reported recurrence after FSS for EOC. Four series comprising 545 patients undergoing FSS and 63 (12%) recurrences. FSS (salpingo-oophorectomy for a majority of cases) for EOC. Recurrences rates and characteristics of recurrent disease. Among 63 recurrent patients, 24 (38%) recurrences were isolated on the spared ovary, and 39 (62%) arose at an extraovarian site. Among the patients with an isolated ovarian recurrence, three patients died after a median follow-up period of 186 months (range: 28-294 months). Among the patients with recurrent extraovarian disease, 24 died and 7 were alive with persistent disease after a median follow-up period of 34 months (range: 3-231 months). The overall rate of isolated ovarian and extrapelvic recurrences was higher for grade 3 tumors (compared with grades 1/2). The long-term survival of patients with an isolated ovarian recurrence after FSS for EOC remains favorable. The prognosis of patients with an extraovarian recurrence is poor compared with those who have an isolated recurrent ovarian tumor. Grade 3 tumors (compared to grades 1/2) give rise to a higher rate of extraovarian recurrences. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc.

We examined the impact of cervical dystonia (CD) and long-term botulinum toxin (BTX) treatment on employment status. Data on employment status at onset of CD, at initiation of BTX treatment, and at evaluation of long-term treatment were obtained from 62 CD patients aged 31-66 years (median, 53 years; 61% females) who had been treated for a median of 5 years (range, 1.5-10 years). The employment rate fell from 84% at the onset of CD to 47% before initiation of BTX treatment. With long-term BTX treatment, 72% of those who worked at the initiation of treatment stayed employed, and 67% of those on sick leave returned to work. A younger age and a higher level of education increased the probability of being employed and avoiding disability benefits. Among those who were younger than 55 years at evaluation of BTX treatment (n = 40), the employment rate increased from 47% to 65% with treatment, and among the male patients, it reached the level of the general population (86%). About half of the 34% who received disability benefits did so already before the BTX treatment was initiated.

Complaints of loss of memory and lack of concentration have been reported by long-term survivors of breast cancer. This mild cognitive impairment (MCI), also called "chemobrain" or "chemofog," has been the subject of a number of studies in the last few years. This cognitive impairment, although usually mild, must be studied to define possible risk factors for its development, and for future research into a preventive or therapeutic treatment approach. Long-term survivors of breast cancer must be followed to detect possible treatment sequelae as soon as possible. Since the number of these long-term survivors has increased in the last years, in part because of more active adjuvant treatments, our knowledge about the long-term side effects of these therapies has also grown.

Bivalirudin use as a procedural anticoagulant in patients undergoing percutaneous coronary intervention (PCI) is associated with a lower incidence of thrombocytopaenia compared to other antithrombotic agents. We aimed to evaluate the prognostic impact of baseline thrombocytopaenia and early changes in platelet counts among patients undergoing PCI with exclusive use of bivalirudin. We evaluated 7,505 patients who underwent PCI over a period of eight years. Patients who received unfractionated heparin and glycoprotein IIb/IIIa receptor inhibitors were specifically excluded. Eight hundred and fifty-eight (11.4%) patients had baseline thrombocytopaenia and 451 (6.0%) developed acquired thrombocytopaenia. After adjustment for potential covariates, moderate to severe acquired thrombocytopaenia was the strongest independent predictor (HR 4.34, 95% CI: 2.13-8.84; p<0.001) of in-hospital net adverse clinical events, which included major adverse cardiac events and major bleeding complications. Age, male gender, baseline platelet count and intra-aortic balloon pump (IABP) insertion were independent predictors of in-hospital acquired thrombocytopaenia. After a mean follow-up of 2.6±1.7 years, moderate to severe baseline thrombocytopaenia (HR 2.42, 95% CI: 1.79-3.29; p<0.001), moderate to severe acquired thrombocytopaenia (HR 2.37, 95% CI: 1.13-4.97; p=0.02) and severe changes in platelet count (>67 k) were significant predictors of mortality. In patients undergoing PCI with bivalirudin, moderate to severe baseline and acquired thrombocytopaenia along with severe changes in platelet count are associated with higher long-term mortality.

Clinical studies have shown an association between long-term anticholinergic (AC) drug exposure and Alzheimer's disease (AD) pathogenesis, which has been primarily investigated in Parkinson's disease (PD). However, long-term AC exposure as a risk factor for developing neurodegenerative disorders and the exact mechanisms and potential for disease progression remain unclear. Here, we have addressed the issue using trihexyphenidyl (THP), a commonly used AC drug in PD patients, to determine if THP can accelerate AD-like neurodegenerative progression and study potential mechanisms involved. Male Sprague-Dawley rats (SD) were intraperitoneally injected with THP (0.3 and 1.0 mg/kg) or normal saline (NS) for 7 months. Alterations in cognitive and behavioral performance were assessed using the Morris water maze (MWM) and open field tests. After behavior tests, whole genome oligo microarrays, quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR), immunohistochemistry, and immunofluorescence-confocal were used to investigate the global mechanisms underlying THP-induced neuropathology with aging. Compared with NS controls, the MWM test results showed that THP-treated rats exhibited significantly extended mean latencies during the initial 3 months of testing; however, this behavioral deficit was restored between the fourth and sixth month of MWM testing. The same tendencies were confirmed by MWM probe and open field tests. Gene microarray analysis identified 68 (47 %) upregulated and 176 (53 %) downregulated genes in the "THP-aging" vs. "NS-aging" group. The most significant populations of genes downregulated by THP were the immune response-, antigen processing and presentation-, and major histocompatibility complex (MHC)-related genes, as validated by qRT-PCR. The decreased expression of MHC class I in THP-treated aging brains was confirmed by confocal analysis. Notably, long-term THP treatment primed hippocampal and cortical microglia to undergo an inflammatory phenotypic switch, causing microgliosis and microglia activation, which were positively accompanied by pathological misfolded tau lesions. Our findings suggest that immune response and neuroinflammation represent a pivotal mechanism in THP-induced AD-like neuropathology processes with long-term exposure to AC drugs.

Surgical ablation, concomitant with other operations, is an option for treatment in patients with chronic atrial fibrillation. The aim of this study is to present a literature review on surgical ablation of atrial fibrillation in patients undergoing cardiac surgery, considering energy sources and return to sinus rhythm. A comprehensive survey was performed in the literature on surgical ablation of atrial fibrillation considering energy sources, sample size, study type, outcome (early and late), and return to sinus rhythm. Analyzing studies with immediate results (n=5), the percentage of return to sinus rhythm ranged from 73% to 96%, while those with long-term results (n=20) (from 12 months on) ranged from 62% to 97.7%. In both of them, there was subsequent clinical improvement of patients who underwent ablation, regardless of the energy source used. Surgical ablation of atrial fibrillation is essential for the treatment of this arrhythmia. With current technology, it may be minimally invasive, making it mandatory to perform a procedure in an attempt to revert to sinus rhythm in patients requiring heart surgery.

We investigated properties of the "Orgamax" osteoplastic material, which was produced from a demineralized bone, in the treatment of extensive caries, in particular chronic pulpitis of the permanent teeth with unformed roots in children. The "Orgamax" osteoplastic material consists of demineralized bone chips, a collagen additive, and antibiotics. The surface morphology of the "Orgamax" osteoplastic material is macroporous, with the maximum pore size of 250 µm, whereas the surface morphology of the major component of "Orgamax", demineralized bone chips, is microporous, with a pore size of 10-20 µm. Material "Orgamax" is used in the treatment of complicated caries, particularly chronic pulpitis of permanent teeth with unformed roots in children. "Orgamax" filling a formed cavity exhibits antimicrobial properties, eliminates inflammation in the dental pulp, and, due to its osteoconductive and osteoinductive properties, undergoes gradual resorption, stimulates regeneration, and provides replacement of the defect with newly formed tissue. The dental pulp viability is completely restored, which ensures the complete formation of tooth roots with root apex closure in the long-term period.

History and evolution of TMD concepts.

PubMed

McNeill, C

1997-01-01

Historically the field of temporomandibular disorders (TMD) has been based on testimonials, clinical opinion, and blind faith rather than on science. Reparative procedures to the joints, jaws, or occlusal surfaces of the teeth to develop idealized structural relationships that may be required for dental health and function are less likely to be required for the management of chronic musculoskeletal disorders. Because of the concerns of many people today regarding professional credibility and intellectual honesty, the need for a scientific foundation to support the various belief systems is of paramount importance. In fact, therapeutic approaches for TMD are undergoing a major evolution away from the traditional mechanistic dental concepts of the past to the more current biopsychosocial medical concepts that emphasize multidisciplinary approaches. Recent advances in the understanding of pain mechanisms and management of chronic pain have improved long-term treatment outcome. The emphasis is on treatment that involves the patient in the physical and behavioral management of their own problem. The majority of patients with TMD achieve good relief of their symptoms with noninvasive, conservative therapy.

State-of-the-Art Review of Echocardiographic Imaging in the Evaluation and Treatment of Functional Tricuspid Regurgitation.

Hahn, Rebecca T

2016-12-01

Functional or secondary tricuspid regurgitation (TR) is the most common cause of severe TR in the Western world. The presence of functional TR, either isolated or in combination with left heart disease, is associated with unfavorable natural history. Surgical mortality for isolated tricuspid valve interventions remains higher than for any other single valve surgery, and surgical options for repair do not have consistent long-term durability. In addition, as more patients undergo transcatheter left valve interventions, developing transcatheter solutions for functional TR has gained greater momentum. Numerous transcatheter devices are currently in early clinical trials. All patients require an assessment of valve morphology and function, and transcatheter devices typically require intraprocedural guidance by echocardiography. The following review will describe tricuspid anatomy, define echocardiographic views for evaluating tricuspid valve morphology and function, and discuss imaging requirements for the current transcatheter devices under development for the treatment of functional TR. © 2016 American Heart Association, Inc.

Encapsulating peritoneal sclerosis (EPS) is a fatal complication that can occur in patients undergoing long-term peritoneal dialysis. It is characterized by bowel obstruction and marked sclerotic thickening of the peritoneal membrane. Although the mechanisms underlying the development of EPS are complex, angiogenesis, inflammation, and peritoneal fibrosis are known to be essential factors. Now, several animal models that exhibit EPS have pathophysiology similar to that of human EPS and have been proposed for use in research to provide insights into it. Recent histochemical methods also help us to understand the pathophysiology of EPS. Advances in basic research based on the findings in those animal models have enabled the development of several strategies for the prevention and treatment of EPS. We describe here interventional studies in some animal models for peritoneal fibrosis, one of the histological disorders findings characteristic to EPS, and we highlight the need for a sophisticated animal model that closely resembles human conditions.

Concurrent regional and global environmental changes are affecting freshwater ecosystems. Decadal-scale data on lake ecosystems that can describe processes affected by these changes are important as multiple stressors often interact to alter the trajectory of key ecological phenomena in complex ways. Due to the practical challenges associated with long-term data collections, the majority of existing long-term data sets focus on only a small number of lakes or few response variables. Here we present physical, chemical, and biological data from 28 lakes in the Adirondack Mountains of northern New York State. These data span the period from 1994-2012 and harmonize multiple open and as-yet unpublished data sources. The dataset creation is reproducible and transparent; R code and all original files used to create the dataset are provided in an appendix. This dataset will be useful for examining ecological change in lakes undergoing multiple stressors.

Selective anterior mesial temporal lobe (AMTL) resection is considered a safe and effective treatment for medically refractory mesial temporal lobe epilepsy (MTLE). However, as with any open surgical procedure, older patients (aged 50+) face greater risks. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) has shown recent potential as an alternative treatment for MTLE. As a less invasive procedure, MRgLITT could be particularly beneficial to older patients. To our knowledge, no study has evaluated the safety and efficacy of MRgLITT in this population. Seven consecutive patients (aged 50+) undergoing MRgLITT for MTLE were followed prospectively to assess surgical time, complications, postoperative pain control, length of stay (LOS), operating room (OR) charges, total hospitalization charges, and seizure outcome. Five of these patients were assessed at the 1-year follow-up for seizure outcome. These data were compared with data taken from 7 consecutive patients (aged 50+) undergoing AMTL resection. Both groups were of comparable age (mean: 60.7 (MRgLITT) vs. 53 (AMTL)). One AMTL resection patient had a complication of aseptic meningitis. One MRgLITT patient experienced an early postoperative seizure, and two MRgLITT patients had a partial visual field deficit. Seizure-freedom rates were comparable (80% (MRgLITT) and 100% (AMTL) (p>0.05)) beyond 1year postsurgery (mean follow-up: 1.0years (MRgLITT) vs. 1.8years (AMTL)). Mean LOS was shorter in the MRgLITT group (1.3days vs. 2.6days (p<0.05)). Neuropsychological outcomes were comparable. Short-term follow-up suggests that MRgLITT is safe and provides outcomes comparable to AMTL resection in this population. It also decreases pain medication requirement and reduces LOS. Further studies are necessary to assess the long-term efficacy of the procedure. Copyright © 2015 Elsevier Inc. All rights reserved.

Diabetes mellitus affects ion channel physiology. We have previously reported that acute application of insulin suppresses the KCNQ1/KCNE1 currents that play an important role in terminating ventricular action potential. In this study, we investigated the effect of long-term insulin treatment on KCNQ1/KCNE1 currents using the Xenopus oocyte expression system. Insulin treatment with a duration longer than 6 h had an opposite effect to acute insulin application, that is, it augmented the KCNQ1/KCNE1 currents. Inhibitors of PI3K, wortmannin and LY294002, and a MEK inhibitor, U0126, abolished the potentiating effect of long-term insulin treatment. The long-term treatment with insulin had no effect on KCNQ1 currents indicating an essential role of KCNE1 in the insulin effect, which is similar to the acute insulin effect. Cycloheximide, an inhibitor of protein synthesis, and brefeldin A, an inhibitor of protein transport from endoplasmic reticulum, suppressed the long-term insulin effect. Western blotting analysis combined with these pharmacological data suggest that long-term insulin treatment augments KCNQ1/KCNE1 currents by increasing KCNE1 protein expression.

Educational computer games are examples of computer-assisted learning objects, representing an educational strategy of growing interest. Given the changes in the digital world over the last decades, students of the current generation expect technology to be used in advancing their learning requiring a need to change traditional passive learning methodologies to an active multisensory experimental learning methodology. The objective of this study was to compare a computer game-based learning method with a traditional learning method, regarding learning gains and knowledge retention, as means of teaching head and neck Anatomy and Physiology to Speech-Language and Hearing pathology undergraduate students. Students were randomized to participate to one of the learning methods and the data analyst was blinded to which method of learning the students had received. Students' prior knowledge (i.e. before undergoing the learning method), short-term knowledge retention and long-term knowledge retention (i.e. six months after undergoing the learning method) were assessed with a multiple choice questionnaire. Students' performance was compared considering the three moments of assessment for both for the mean total score and for separated mean scores for Anatomy questions and for Physiology questions. Students that received the game-based method performed better in the pos-test assessment only when considering the Anatomy questions section. Students that received the traditional lecture performed better in both post-test and long-term post-test when considering the Anatomy and Physiology questions. The game-based learning method is comparable to the traditional learning method in general and in short-term gains, while the traditional lecture still seems to be more effective to improve students' short and long-term knowledge retention.

Patients with untreated gallbladder stones in situ are at high risk for late biliary complications after endoscopic papillary balloon dilation (EPBD) and bile duct stone extraction. Few data exist on the short-term and long-term results in these patients after the recurrence of bile duct stones and acute cholecystitis. The aim of this study was to evaluate the outcome of late biliary complications in patients with gallbladder stones in situ after EPBD. Fifty-six patients who developed late biliary complications, including bile duct stone recurrence (n=43) and acute cholecystitis (n=13), were managed at our institutions. We investigated the short-term and long-term outcomes after the management of late biliary complications. Complete removal of recurrent bile duct stones was achieved in 38 of 43 patients (88%) by repeated EPBD alone. Pancreatitis after repeated EPBD occurred in two patients (5%). After successful bile duct stone extraction by EPBD, none of the 16 patients who underwent cholecystectomy developed late biliary complications (mean follow-up period of 5.2 years), wheras re-recurrent bile duct stones occurred in three of the 21 patients (14%) with gallbladder stones left in situ (mean follow-up period of 4.4 years)(P=0.1148). Re-recurrent bile duct stones were successfully treated endoscopically. One of the eight patients who did not undergo cholecystectomy for acute cholecystitis had a recurrence of cholecystitis, which was managed conservatively. The long-term outcomes of late biliary complications are favorable when patients with concomitant gallbladder stones undergo cholecystectomy. Re-recurrent bile duct stones are considerable when gallbladder stones are left in situ, but should be treated endoscopically.

Thanks to widespread diffusion of minimally invasive approach in the setting of both colorectal and hepatic surgeries, the interest in combined resections for colorectal cancer and synchronous liver metastases (SCLM) by totally laparoscopic approach (TLA) has increased. Aim of this study was to compare outcome of combined resections for SCLM performed by TLA or by open approach, in a propensity-score-based study. All 25 patients undergoing combined TLA for SCLM at San Raffaele Hospital in Milano were compared in a case-matched analysis with 25 out of 91 patients undergoing totally open approach (TOA group). Groups were matched with 1:2 ratio using propensity scores based on covariates representing disease severity. Main endpoints were postoperative morbidity and long-term outcome. The Modified Accordion Severity Grading System was used to quantify complications. The groups resulted comparable in terms of patients and disease characteristics. The TLA group, as compared to the TOA group, had lower blood loss (350 vs 600 mL), shorter postoperative stay (9 vs 12 days), lower postoperative morbidity index (0.14 vs 0.20) and severity score for complicated patients (0.60 vs 0.85). Colonic anastomosis leakage had the highest fractional complication burden in both groups. In spite of comparable long-term overall survival, the TLA group had better recurrence-free survival. TLA for combined resections is feasible, and its indications can be widened to encompass a larger population of patients, provided its benefits in terms of reduced overall risk and severity of complications, rapid functional recovery and favorable long-term outcomes.

The long-term prognosis of patients undergoing colectomy for fulminant Clostridium difficile colitis has not been well studied. The authors present 7-year survival trends in such patients. Patients were identified through a pathologic database. Medical records were reviewed and follow-up phone calls made to determine relevant patient history, longevity, and quality of life. The 61 patients identified had mean and median survival of 18.1 and 3.2 months, respectively, and 1-year, 2-year, 5-year, and 7-year mortality of 68.5%, 79.6%, 88.9%, and 90.7%, respectively. Previous C difficile infection, hypotension, requirement of vasopressors, mental status changes, elevated arterial lactate, decreased platelet counts, intubation, and longer duration on nonoperative therapy were associated with in-hospital mortality. There were no factors correlated with long-term survival. Patients who require colectomy for fulminant C difficile colitis have a poor prognosis with poor long-term survival and significant morbidity. Although there are several factors associated with in-hospital mortality, there were no factors correlated with long-term survival. Copyright © 2014 Elsevier Inc. All rights reserved.

The authors investigated the development of pulmonary hypertension (PH), predictors of PH regression, and its prognostic impact on short, mid-, and long-term outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). PH represents a common finding in patients with AS. Although TAVR is frequently associated with regression of PH, the predictors of reversible PH and its prognostic significance remain uncertain. In this study, 617 consecutive patients undergoing TAVR between 2009 and 2015 were stratified per baseline tertiles of pulmonary artery systolic pressure (PASP) as follows: normal (PASP <34 mm Hg), mild-to-moderate (34 mm Hg ≤ PASP <46 mm Hg), and severe PASP elevation (PASP ≥46 mm Hg). After TAVR, 520 patients with PH at discharge were stratified according to the presence or absence of PASP reduction. Primary outcome was all-cause mortality at 30 days, 1 year, and long-term follow-up at a maximum of 5.9 years. In patients with both mild-to-moderate and severe PH at baseline, PASP decreased significantly at discharge (ΔPASP 3.0 ± 9.3 mm Hg and 12.0 ± 10.0 mm Hg, respectively) and 1 year (ΔPASP 5.0 ± 9.7 mm Hg and 18.0 ± 14.0 mm Hg, respectively). At a median follow-up of 370 days (interquartile range [IQR]: 84 to 500 days), the risk of all-cause mortality was similar among baseline PASP groups at all time intervals evaluated. After TAVR, a significant regression of PH was observed in 46% of patients. Contrarily, patients with residual PH had a higher risk of all-cause mortality at 30 days (hazard ratio [HR]: 3.49, 95% confidence interval [CI]: 1.74 to 6.99; p < 0.001), 1 year (HR: 3.12, 95% CI: 2.06 to 4.72; p < 0.001), and long-term (HR: 2.47, 95% CI: 1.74 to 3.49; p < 0.001). Left ventricular ejection fraction (LVEF) >40% (odds ratio [OR]: 3.56, 95% CI: 2.24 to 5.65; p < 0.001), baseline PASP ≥46 mm Hg (OR: 3.26, 95% CI: 2.07 to 5.12; p < 0.001), absence of concomitant tricuspid regurgitation (TR) ≥ moderate (OR: 0.53, 95% CI: 0.34 to 0.84; p < 0.001), and logistic EuroSCORE <25% (OR: 1.59, 95% CI: 1.04 to 2.45; p = 0.03) were independent predictors of PASP reduction. In most patients with PH and AS, TAVR is associated with a significant early and late reduction of PASP. Patients with reversible PH after TAVR are at lower risk of all-cause mortality at early, mid-, and long-term follow-up. Therefore, the presence of PH should not preclude treatment with TAVR.

Long-term psychosocial consequences of surgical congenital malformations.

PubMed

Diseth, Trond H; Emblem, Ragnhild

2017-10-01

Surgical congenital malformations often represent years of treatment, large number of hospital stays, treatment procedures, and long-term functional sequels affecting patients' psychosocial functioning. Both functional defects and psychosocial difficulties that occur commonly in childhood may pass through adolescence on to adulthood. This overview presents reports published over the past 3 decades to elucidate the long-term psychosocial consequences of surgical congenital malformations. Literature searches conducted on PubMed database revealed that less than 1% of all the records of surgical congenital malformations described long-term psychosocial consequences, but with diverse findings. This inconsistency may be due to methodological differences or deficiencies; especially in study design, patient sampling, and methods. Most of the studies revealed that the functional deficits may have great impact on patients' mental health, psychosocial functioning, and QoL; both short- and long-term negative consequences. Factors other than functional problems, e.g., repeated anesthesia, multiple hospitalization, traumatic treatment procedures, and parental dysfunctioning, may also predict long-term mental health and psychosocial functioning. Through multidisciplinary approach, pediatric surgeons should also be aware of deficits in emotional and psychosocial functioning. To achieve overall optimal psychosocial functioning, the challenge is to find a compromise between physically optimal treatment procedures and procedures that are not psychologically detrimental.

Effects of recreational soccer in men with prostate cancer undergoing androgen deprivation therapy: study protocol for the ‘FC Prostate’ randomized controlled trial

PubMed Central

2013-01-01

Background Androgen deprivation therapy (ADT) is a cornerstone in the treatment of advanced prostate cancer. Adverse musculoskeletal and cardiovascular effects of ADT are widely reported and investigations into the potential of exercise to ameliorate the effects of treatment are warranted. The ‘Football Club (FC) Prostate’ study is a randomized trial comparing the effects of soccer training with standard treatment approaches on body composition, cardiovascular function, physical function parameters, glucose tolerance, bone health, and patient-reported outcomes in men undergoing ADT for prostate cancer. Methods/Design Using a single-center randomized controlled design, 80 men with histologically confirmed locally advanced or disseminated prostate cancer undergoing ADT for 6 months or more at The Copenhagen University Hospital will be enrolled on this trial. After baseline assessments eligible participants will be randomly assigned to a soccer training group or a control group receiving usual care. The soccer intervention will consist of 12 weeks of training 2–3 times/week for 45–60 min after which the assessment protocol will be repeated. Soccer training will then continue bi-weekly for an additional 20 weeks at the end of which all measures will be repeated to allow for additional analyses of long-term effects. The primary endpoint is changes in lean body mass from baseline to 12 weeks assessed by dual X-ray absorptiometry scan. Secondary endpoints include changes of cardiovascular, metabolic, and physical function parameters, as well as markers of bone metabolism and patient-reported outcomes. Discussion The FC Prostate trial will assess the safety and efficacy of a novel soccer-training approach to cancer rehabilitation on a number of clinically important health outcomes in men with advanced prostate cancer during ADT. The results may pave the way for innovative, community-based interventions in the approach to treating prostate cancer. Trial registration ClinicalTrials.gov: NCT01711892 PMID:24330570

Although living in a hilly environment may promote muscular activity in the daily lives of residents, and such activity may prevent diabetes mellitus, few studies have focused on the impact of living in a hilly environment on diabetes mellitus. The purpose of this study was to investigate the impact of a hilly neighborhood environment on DM in older people. We used data from the Japan Gerontological Evaluation Study, a population-based, cross-sectional study of individuals aged 65 or older without long-term care needs in Japan, which was conducted in 2010. A total of 8904 participants in 46 neighborhoods had responded to the questionnaire and undergone a health check. Diabetes mellitus was diagnosed as HbA 1c  ≥ 6.5% and those undergoing treatment for diabetes mellitus. Poorly controlled diabetes mellitus was diagnosed in those without other chronic diseases who had an HbA 1c > 7.5%, and in those with other chronic diseases if their HbA 1c was >8.0%. Neighborhood environment was evaluated based on the percentage of positive responses in the questionnaire and geographical information system data. A multilevel analysis was performed, adjusted for individual-level risk factors. Furthermore, sensitivity analysis was conducted for those who were undergoing treatment for diabetes mellitus (n = 1007). After adjustment for other physical environmental and individual covariates, a 1 interquartile range increase (1.48°) in slope in the neighborhood decreased the risk of poorly controlled diabetes mellitus by 18% (odds ratio [OR]: 0.82, 95% confidence interval [CI]: 0.70-0.97). Sensitivity analysis confirmed that larger slopes in the neighborhood showed a significant protective effect against diabetes mellitus among those who were undergoing treatment for diabetes mellitus (OR: 0.73, 95% CI: 0.59-0.90). A hilly neighborhood environment was not associated with diabetes mellitus, but was protective against poorly controlled diabetes mellitus. Copyright © 2017 Elsevier Ltd. All rights reserved.

Due to disparities in access to care, patients with Medicaid or no health insurance are at risk of not receiving appropriate adjuvant treatment following resection of pancreatic cancer. We have previously shown inferior short-term outcomes following surgery at safety-net hospitals. Subsequently, we hypothesized that safety-net hospitals caring for these vulnerable populations utilize less adjuvant chemoradiation, resulting in inferior long-term outcomes. The American College of Surgeons National Cancer Data Base was queried for patients diagnosed with pancreatic adenocarcinoma (n = 32,296) from 1998 to 2010. Hospitals were grouped according to safety-net burden, defined as the proportion of patients with Medicaid or no insurance. The highest quartile, representing safety-net hospitals, was compared to lower-burden hospitals with regard to patient demographics, disease characteristics, surgical management, delivery of multimodal systemic therapy, and survival. Patients at safety-net hospitals were less often white, had lower income, and were less educated. Safety-net hospital patients were just as likely to undergo surgical resection (OR 1.03, p = 0.73), achieving similar rates of negative surgical margins when compared to patients at medium and low burden hospitals (70% vs. 73% vs. 66%). Thirty-day mortality rates were 5.6% for high burden hospitals, 5.2% for medium burden hospitals, and 4.3% for low burden hospitals. No clinically significant differences were noted in the proportion of surgical patients receiving either chemotherapy (48% vs. 52% vs. 52%) or radiation therapy (26% vs. 30% vs. 29%) or the time between diagnosis and start of systemic therapy (58 days vs. 61 days vs. 53 days). Across safety-net burden groups, no difference was noted in stage-specific median survival (all p > 0.05) or receipt of adjuvant as opposed to neoadjuvant systemic therapy (82% vs. 85% vs. 85%). Multivariate analysis adjusting for cancer stage revealed no difference in survival for safety-net hospital patients who had surgery and survived > 30 days (HR 1.02, p = 0.63). For patients surviving the perioperative setting following pancreatic cancer surgery, safety-net hospitals achieve equivalent long-term survival outcomes potentially due to equivalent delivery of multimodal therapy at non-safety-net hospitals. Safety-net hospitals are a crucial resource that provides quality long-term cancer treatment for vulnerable populations.

The metabolism and pharmacokinetics of isotretinoin in patients with acne and rosacea are not influenced by ethanol.

Isotretinoin is effective in the treatment of severe acne and rosacea. Both parent drug and its main metabolite 4-oxo-isotretinoin are potentially teratogenic compounds and contain a carboxylic acid moiety. In the presence of ethanol, naturally occurring as well as synthetic retinoids also containing a carboxylic acid moiety are capable of undergoing an ethyl esterification with the metabolic formation of more lipophilic compounds with a much longer terminal half-life. To determine if isotretinoin (13-cis-RA), its main metabolite 4-oxo-isotretinoin (4-oxo-13-cis-RA), and other possible metabolites in the presence or absence of ethanol are converted to their corresponding ethyl derivatives in patients with severe acne or rosacea after multiple isotretinoin dosing. In addition, pharmacokinetic parameters of the parent drug and its 4-oxo metabolite were determined. Eleven patients with severe acne or rosacea were treated with isotretinoin daily for 3 months and investigated pharmacokinetically during 24 h after 1 month of treatment and for up to 28 days after discontinuation of therapy. A possible influence of ethanol was evaluated using a simple self-administered questionnaire and by measuring serum ethanol levels during treatment. The concentrations of isotretinoin, 4-oxo-isotretinoin and possible ethylated and nonethylated metabolites were measured by reverse-phase high-performance liquid chromatography. Although seven of 11 patients had a considerable weekly alcohol intake, no endogenous synthesis of ethyl derivatives of isotretinoin, the main 4-oxo metabolite or the all-trans compounds was chromatographically detectable in any of the patients' plasma samples during the treatment period. Multiple dose pharmacokinetic data for the parent drug and its main metabolite were comparable to previous studies. The metabolism and pharmacokinetics of isotretinoin and its main metabolites are not influenced by ethanol during long-term isotretinoin treatment. After ceasing long-term isotretinoin therapy the recommended period of 1 month for using anticonceptive measures in fertile women seems adequate.

Clinical strategies to address patients' concerns in osteoporosis management with bisphosphonates.

PubMed

Cole, Raymond E

2011-03-01

Approximately 44 million Americans either have, or are at risk of developing, osteoporosis, a disease associated with an increased risk of fracture and, consequently, morbidity and mortality. Osteoporosis affects 20% to 30% of postmenopausal women, and resulting fractures pose a major economic burden, with estimated annual direct costs ranging from $17 billion to $19 billion. Hip fractures account for the majority of costs (~60%) because they often require costly long-term follow-up care in addition to the direct costs of initial treatment. Screening, diagnosis, and disease management are of paramount importance when treating patients at risk for osteoporosis. The National Osteoporosis Foundation recommends that all postmenopausal women be evaluated for osteoporosis risk factors and that all women aged ≥ 65 years undergo bone mineral density testing. Once the primary care physician has identified a patient at risk for osteoporosis-related fracture, the physician must decide whether and how to treat the patient (ie, nonpharmacologic or pharmacologic options). Bisphosphonates are the first-line pharmacologic treatment for women aged ≥ 50 years with postmenopausal osteoporosis. Bisphosphonates-which have a favorable safety and tolerability profile in clinical trials-have shown efficacy in reducing fractures. However, achieved real world effectiveness is very much dependent on good treatment adherence by the patient. Media attention to rare adverse events has motivated some patients to deliberate nonadherence. Physicians should screen patients for contraindications and adverse event risk factors, educate them on the risks of fracture and benefits and risks of treatment, and monitor them during therapy. To assist primary care physicians in clinical decision making for women at risk for or with confirmed osteoporosis, this article presents a review of the guidelines for the diagnosis and treatment of postmenopausal osteoporosis, recent long-term efficacy data for extended-interval bisphosphonates, recent safety concerns with bisphosphonates, and lastly, suggests strategies for improving bisphosphonate adherence and patient outcomes.

Introduction: This randomized, cross-over, double-blind, controlled study of continuous intrathecal morphine administration in patients with severe, long-term pain addresses whether the supplementation of low doses of naloxone in this setting is associated with beneficial clinical effects. Methods: All of the study subjects (n=11) provided informed consent and were recruited from a subset of patients who were already undergoing long-term treatment with continuous intrathecal morphine because of difficult-to-treat pain. The patients were (in a randomized order) also given intrathecal naloxone (40 ng/24 h or 400 ng/24 h). As control, the patients’ ordinary dose of morphine without any additions was used. The pain (Numeric Rating Scale, NRS) during activity, perceived quality of sleep, level of activity, and quality of life as well as the levels of several proinflammatory and anti-inflammatory cytokines in the blood were assessed. The prestudy pain (NRS during activity) in the study group ranged from 3 to 10. Results: A total of 64% of the subjects reported improved quality of sleep during treatment with naloxone at a dose of 40 ng per 24 hours as compared with 9% with sham treatment (P=0.024). Although not statistically significant, pain was reduced by 2 NRS steps or more during supplemental treatment with naloxone in 36% of subjects when using the 40 ng per 24 hours dose and in 18% of the subjects when using naloxone 400 ng per 24 hours dose. The corresponding percentage among patients receiving unaltered treatment was 27%. Conclusions: To conclude, the addition of an ultralow dose of intrathecal naloxone (40 ng/24 h) to intrathecal morphine infusion in patients with severe, persistent pain improved perceived quality of sleep. We were not able to show any statistically significant effects of naloxone on pain relief, level of activity, or quality of life. PMID:25629634

"Gynecomastia" is an enlargement of the male breast. Our study aims to assess patient satisfaction as well as evaluate differences in recurrence rates in lipomatous and glandular gynecomastia 10-19 years postoperatively. Forty-one gynecomastia patients undergoing surgical treatment from 1997 to 2005 were invited for a follow-up examination 10-19 years postoperatively. Of these, 16 patients presented for a clinical examination. Patient satisfaction was measured with a validated questionnaire [consultation satisfaction questionnaire (CSQ)-9]. Furthermore, photo-material and patient charts were evaluated concerning preoperative macroscopical type of gynecomastia, BMI, and operative technique. Mean follow-up time was 13.8 years (range: 10.5-19 years). Eight patients (50%) had presented with lipomatous and eight patients (50%) with glandular gynecomastia prior to surgery. One of the patients with glandular gynecomastia (12.5%) presented with recurrence at the time of follow-up, while five of the eight patients showing lipomatous gynecomastia (62.5%) presented with recurrence. Interestingly, younger patient groups tend to be more satisfied with the operative treatment of gynecomastia than older patient groups, especially regarding the improvement of self-esteem. Long-term follow-up results showed that recurrence rates are significantly higher in patients with lipomatous gynecomastia than in patients with glandular gynecomastia, with BMI increase in patients with glandular and lipomatous gynecomastia showing no statistically significant differences. Furthermore, general patient satisfaction and improvement of self-esteem was higher in younger patient groups than older patient groups.

Health-related quality of life (HRQL), life satisfaction, living conditions, patients' attitudes towards life and death, expectations, beliefs and unmet needs are all poorly understood aspects associated with patients receiving invasive home mechanical ventilation (HMV) following ICU treatment and unsuccessful weaning. Therefore, the present study aimed to assess (1) HRQL, (2) life satisfaction and (3) patients' perspectives on life and death associated with invasive HMV as the consequence of unsuccessful weaning. Patients undergoing invasive HMV with full technical supply and maximal patient care were screened over a 1-year period and assessed in their home environment. The study comprised the following: (1) detailed information on specific aspects of daily life, (2) self-evaluation of 23 specific daily life aspects, (3) HRQL assessment using the Severe Respiratory Insufficiency Questionnaire, (4) open interviews about the patient's living situation, HRQL, unsolved problems, treatment options, dying and the concept of an afterlife. Out of 112 patients admitted to a specialized weaning centre, 50 were discharged with invasive HMV and 25 out of these (14 COPD and 11 neuromuscular patients) were ultimately enrolled. HRQL and life satisfaction were severely impaired, despite maximal patient care and full supply of technical aids. The most important areas of dissatisfaction identified were mobility, communication, social contact and care dependency. Importantly, 32% of patients would have elected to die in hindsight rather than receive invasive HMV. Despite maximal patient care and a full supply of technical aids, both HRQL and life satisfaction are severely impaired in many invasive HMV patients who have failed prolonged weaning. These findings raise ethical concerns about the use of long-term invasive HMV following unsuccessful weaning.

Lowering of blood pressure by chronic suppression of central sympathetic outflow: insight from prolonged baroreflex activation

PubMed Central

Iliescu, Radu

2012-01-01

Device-based therapy for resistant hypertension by electrical activation of the carotid baroreflex is currently undergoing active clinical investigation, and initial findings from clinical trials have been published. The purpose of this mini-review is to summarize the experimental studies that have provided a conceptual understanding of the mechanisms that account for the long-term lowering of arterial pressure with baroreflex activation. The well established mechanisms mediating the role of the baroreflex in short-term regulation of arterial pressure by rapid changes in peripheral resistance and cardiac function are often extended to long-term pressure control, and the more sluggish actions of the baroreflex on renal excretory function are often not taken into consideration. However, because clinical, experimental, and theoretical evidence indicates that the kidneys play a dominant role in long-term control of arterial pressure, this review focuses on the mechanisms that link baroreflex-mediated reductions in central sympathetic outflow with increases in renal excretory function that lead to sustained reductions in arterial pressure.

Background Evidence suggests that high-dose statin pretreatment may reduce the risk of periprocedural myocardial infarction (PMI) and major adverse cardiac events (MACE) for certain patients; however, previous analyses have not considered patients with a history of statin maintenance treatment. In this meta-analysis of randomized controlled trials (RCTs), we reevaluated the efficacy of short-term high-dose statin pretreatment to prevent PMI and MACE in an expanded set of patients undergoing elective percutaneous coronary intervention. Methods We searched the PubMed/Medline database for RCTs that compared high-dose statin pretreatment with no statin or low-dose statin pretreatment as a prevention of PMI and MACE. We evaluated the incidence of PMI and MACE, including death, spontaneous myocardial infarction, and target vessel revascularization at the longest follow-up for each study for subgroups stratified by disease classification and prior low-dose statin treatment. Results Twenty-four RCTs with a total of 5,526 patients were identified. High-dose statin pretreatment was associated with 59% relative reduction in PMI (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34–0.49; P<0.00001) and 39% relative reduction in MACE (OR: 0.61; 95% CI: 0.45–0.83; P = 0.002). The benefit of high-dose statin pretreatment on MACE was significant for statin-naive patients (OR: 0.69; 95% CI: 0.50–0.95; P = 0.02) and prior low dose statin-treated patients (OR: 0.28; 95% CI: 0.12–0.65; P = 0.003); and for patients with acute coronary syndrome (OR: 0.52; 95% CI: 0.34–0.79; P = 0.003), but not for patients with stable angina (OR: 0.71; 95% CI 0.45–1.10; P = 0.12). Long-term effects on survival were less obvious. Conclusions High-dose statin pretreatment can result in a significant reduction in PMI and MACE for patients undergoing elective PCI. The positive effect of high-dose statin pretreatment on PMI and MACE is significant for statin-naïve patients and patients with prior treatment. The positive effect of high-dose statin pretreatment on MACE is significant for patients with acute coronary syndrome. PMID:25473831

To compare in a prospective, randomized trial the long-term results of laparoscopic Heller myotomy plus Dor fundoplication versus laparoscopic Heller myotomy plus floppy-Nissen for achalasia. Anterior fundoplication is usually performed after Heller myotomy to control GER; however, the incidence of postoperative GER ranges between 10% and 30%. Total fundoplication may aid in reducing GER rates. From December 1993 to September 2002, 153 patients with achalasia underwent Heller laparoscopic myotomy plus antireflux fundoplication. Of these, 9 were excluded from the study. The remaining 144 patients were randomly assigned to 2 treatment groups: Heller laparoscopic myotomy plus anterior fundoplication (Dor procedure) or Heller laparoscopic myotomy plus total fundoplication (floppy-Nissen procedure). The primary end point was incidence of clinical and instrumental GER after a minimum of 60 months follow-up. The secondary end point was recurrence of dysphagia. Follow-up clinical assessments were performed at 1, 3, 12, and 60 months using a modified DeMeester Symptom Scoring System (MDSS). Esophageal manometry and 24-hour pH monitoring were performed at 3, 12, and 60 months postoperative. Of the 144 patients originally included in the study, 138 were available for long-term analysis: 71 (51%) underwent antireflux fundoplication plus a Dor procedure (H + D group) and 67 (49%) antireflux fundoplication plus a Nissen procedure (H + N group). No mortality was observed. The mean follow-up period was 125 months. No statistically significant differences in clinical (5.6% vs. 0%) or instrumental GER (2.8% vs. 0%) were found between the 2 groups; however, a statistically significant difference in dysphagia rates was noted (2.8% vs. 15%; P < 0.001). Although both techniques achieved long-term GER control, the recurrence rate of dysphagia was significantly higher among the patients who underwent Nissen fundoplication. This evidence supports the use of Dor fundoplication as the preferred method to re-establish GER control in patients undergoing laparoscopic Heller myotomy.

Survivors of childhood cancer are at an increased risk of developing subsequent neoplasms. In long-term survivors of childhood malignancies treated with and without cranial radiation therapy (CRT), undergoing unenhanced magnetic resonance imaging (MRI) of the brain, we estimated detection of intracranial neoplasms. To investigate neurocognitive outcomes, 219 survivors of childhood cancer underwent unenhanced screening MRI of the brain. Of the survivors, 164 had been treated for acute lymphoblastic leukemia (ALL) (125 received CRT) and 55 for Hodgkin lymphoma (HL) (none received CRT). MRI examinations were reviewed and systematically coded by a single neuroradiologist. Demographic and treatment characteristics were compared for survivors with and without subsequent neoplasms. Nineteen of the 219 survivors (8.7 %) had a total of 31 subsequent intracranial neoplasms identified by neuroimaging at a median time of 25 years (range 12-46 years) from diagnosis. All neoplasms occurred after CRT, except for a single vestibular schwannoma within the cervical radiation field in a HL survivor. The prevalence of subsequent neoplasms after CRT exposure was 14.4 % (18 of 125). By noncontrast MRI, intracranial neoplasms were most suggestive of meningiomas. Most patients presented with no specific, localizing neurological complaints. In addition to the schwannoma, six tumors were resected based on results of MRI screening, all of which were meningiomas on histologic review. Unenhanced brain MRI of long-term survivors of childhood cancer detected a substantial number of intracranial neoplasms. Screening for early detection of intracranial neoplasms among aging survivors of childhood cancer who received CRT should be evaluated. The high prevalence of incidentally detected subsequent intracranial neoplasms after CRT in long-term survivors of childhood cancer and the minimal symptoms reported by those with intracranial tumors in our study indicate that brain MRI screening of long-term survivors who received CRT may be warranted. Prospective studies of such screening are needed.

INTRODUCTION At present, liver resection offers the best long-term outcome and only chance for cure in patients with colorectal liver metastases. However, there are no large series that report the early and long-term outcomes of patients who require simultaneous diaphragm excision. This study was designed to investigate these patients. PATIENTS AND METHODS A total of 285 consecutive liver resections were performed over a 10-year period. Of these, 258 had liver resections alone and 27 underwent liver resection and simultaneous diaphragm excision. Data were collected prospectively and analysed retrospectively. Pre-operative assessment was standardised. The outcomes between the two groups were compared. RESULT There was no difference in age, hospital stay or intra-operative blood loss. The diaphragm was histologically involved in four out of 27 resections. As a result, the cancer involved resection margin incidence was greater in the liver resection and diaphragm excision group (14.8% versus 3.9%; P = 0.12). The median tumour size was also different between the two groups (60 mm versus 30 mm; P = 0.001). The liver and diaphragm resection group had a greater peri-operative complication rate (44.4% versus 21.3%; P = 0.02) and mortality (7.4% versus 1.6%; P = 0.25). Overall and disease-free survival was significantly worse in the group who underwent simultaneous diaphragm excision and liver resection (P = 0.04 and P = 0.005, respectively). Diaphragm invasion was found to be an independent predictor of poor overall outcome (P = 0.02). CONCLUSION Liver resection and simultaneous diaphragm excision have a greater incidence of peri-operative morbidity and mortality and a significantly worse long-term outcome compared with liver resection alone. However, these data suggest that liver resection in the presence of diaphragm invasion may still offer a favourable outcome compared with chemotherapy treatment alone. Therefore, we believe that diaphragm involvement by tumour should not be a contra-indication to hepatectomy. PMID:19558763

Pregnancy in ESRD is rare and poses substantial risk for mother and baby. This study describes a large series of pregnancies in women undergoing long-term dialysis treatment and reviews maternal and fetal outcomes. Specifically, women who had conceived before and after starting long-term dialysis are compared. All pregnancies reported to the Australian and New Zealand Dialysis and Transplantation Registry from 2001 to 2011 (n=77), following the introduction of specific parenthood data collection, were analyzed. Between 2001 and 2011, there were 77 pregnancies among 73 women. Of these, 53 pregnancies were in women who conceived after long-term dialysis was established and 24 pregnancies occurred before dialysis began. The overall live birth rate (after exclusion of elective terminations) was 73%. In pregnancies reaching 20 weeks gestation, the live birth rate was 82%. Women who conceived before dialysis commenced had significantly higher live birth rates (91% versus 63%; P=0.03), but infants had similar birthweight and gestational age. This difference in live birth rate was primarily due to higher rates of early pregnancy loss before 20 weeks in women who conceived after dialysis was established. In pregnancies that reached 20 weeks or more, the live birth rate was higher in women with conception before dialysis commenced (91% versus 76%; P=0.28). Overall, the median gestational age was 33.8 weeks (interquartile range, 30.6-37.6 weeks) and median birthweight was 1750 g (interquartile range, 1130-2417 g). More than 40% of pregnancies reached >34 weeks' gestation; prematurity at <28 weeks was 11.4% and 28-day neonatal survival rate was 98%. Women with kidney disease who start long-term dialysis after conception have superior live birth rates compared with those already established on dialysis at the time of conception, although these pregnancies remain high risk.

In patients with COPD, chronic anemia is known as an unfavorable prognostic factor. Whether the association between hemoglobin (Hb) levels and long-term survival is restricted to anemia or extends to higher Hb levels has not yet been systematically assessed. We determined Hb levels in 309 subjects with COPD and chronic respiratory failure prior to initiation of noninvasive ventilation, accounting for confounders that might affect Hb. Subjects were categorized as anemic (Hb < 12 g/dL in females, Hb < 13 g/dL in males), polycythemic (Hb ≥ 15 g/dL in females, Hb ≥ 17 g/dL in males), or normocythemic. In addition, percentiles of Hb values were analyzed with regard to mortality from any cause. Two-hundred seven subjects (67.0%) showed normal Hb levels, 46 (14.9%) had anemia, and 56 (18.1%) had polycythemia. Polycythemic subjects showed a higher survival rate than anemic (P = .01) and normocythemic subjects (P = .043). In a univariate Cox hazards model, Hb was associated with long-term survival (hazard ratio 0.855; 95% CI 0.783-0.934, P < .001). The 58th percentiles of Hb (14.3 g/dL in females, 15.1 g/dL in males) yielded the highest discriminative value for predicting survival (hazard ratio 0.463, 95% CI 0.324-0.660, P < .001). In the multivariate analysis this cutoff was an independent predictor for survival (hazard ratio 0.627, 95% CI 0.414-0.949, P = .03), in addition to age and body mass index. In subjects with COPD and chronic respiratory failure undergoing treatment with noninvasive ventilation and LTOT, high Hb levels are associated with better long-term survival. The optimal cutoff level for prediction was above the established threshold defining anemia. Thus, predicting survival only on the basis of anemia does not fully utilize the prognostic potential of Hb values in COPD.

2014-05-01

Acute kidney injury develops in up to 30% of patients who undergo cardiac surgery, with up to 3% of patients requiring dialysis. The requirement for dialysis after cardiac surgery is associated with an increased risk of infection, prolonged stay in critical care units and long-term need for dialysis. The development of acute kidney injury is independently associated with substantial short- and long-term morbidity and mortality. Its pathogenesis involves multiple pathways. Haemodynamic, inflammatory, metabolic and nephrotoxic factors are involved and overlap each other leading to kidney injury. Clinical studies have identified predictors for cardiac surgery-associated acute kidney injury that can be used effectively to determine the risk for acute kidney injury in patients undergoing cardiac surgery. High-risk patients can be targeted for renal protective strategies. Nonetheless, there is little compelling evidence from randomized trials supporting specific interventions to protect or prevent acute kidney injury in cardiac surgery patients. Several strategies have shown some promise, including less invasive procedures in those at greatest risk, natriuretic peptide, fenoldopam, preoperative hydration, preoperative optimization of anaemia and postoperative early use of renal replacement therapy. The efficacy of larger-scale trials remains to be confirmed.

SUMMARY Prostate cancer (PCa) is heterogeneous and contains both differentiated and undifferentiated tumor cells, but the relative functional contribution of these two cell populations remains unclear. Here we report distinct molecular, cellular, and tumor-propagating properties of PCa cells that express high (PSA+) and low (PSA−/lo) levels of the differentiation marker PSA. PSA−/lo PCa cells are quiescent and refractory to stresses including androgen deprivation, exhibit high clonogenic potential, and possess long-term tumor-propagating capacity. They preferentially express stem cell genes and can undergo asymmetric cell division generating PSA+ cells. Importantly, PSA−/lo PCa cells can initiate robust tumor development and resist androgen ablation in castrated hosts, and harbor highly tumorigenic castration-resistant PCa cells that can be prospectively enriched using ALDH+CD44+α2β1+ phenotype. In contrast, PSA+ PCa cells possess more limited tumor-propagating capacity, undergo symmetric division and are sensitive to castration. Together, our study suggests PSA−/lo cells may represent a critical source of castration-resistant PCa cells. PMID:22560078

The aim of this study was to characterize the pharmacokinetics (PK) of propofol in ICU patients undergoing long-term sedation and to assess the influence of routinely collected covariates on the PK parameters. Propofol concentration-time profiles were collected from 29 patients. Non-linear mixed-effects modelling in NONMEM 7.2 was used to analyse the observed data. The propofol pharmacokinetics was best described with a three-compartment disposition model. Non-parametric bootstrap and a visual predictive check were used to evaluate the adequacy of the developed model to describe the observations. The typical value of the propofol clearance (1.46 l/min) approximated the hepatic blood flow. The volume of distribution at steady state was high and was equal to 955.1 l, which is consistent with other studies involving propofol in ICU patients. There was no statistically significant covariate relationship between PK parameters and opioid type, SOFA score on the day of admission, APACHE II, predicted death rate, reason for ICU admission (sepsis, trauma or surgery), gender, body weight, age, infusion duration and C-reactive protein concentration. The population PK model was developed successfully to describe the time-course of propofol concentration in ICU patients undergoing prolonged sedation. Despite a very heterogeneous group of patients, consistent PK profiles were observed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Mixed hepatocellular and cholangiocarcinoma (HCC-CC) have been associated with a poor prognosis after liver transplantation (LT). We aimed to evaluate long-term outcomes in patients undergoing LT for HCC-CC versus patients with hepatocellular carcinoma (HCC) or cholangiocarcinoma (CC). Retrospective analysis of the United Network for Organ Sharing (UNOS) database from 1994-2013. Overall survival (OS) in patients with HCC-CC, HCC, and CC, were compared. We identified 4049 patients transplanted for primary malignancy (94 HCC-CC; 3515 HCC; 440 CC). Mean age of patients with HCC-CC was 57 ± 10 years, and 77% were male. MELD score did not differ among the groups (p = 0.637). Hepatitis C virus was the most common secondary diagnosis within the HCC-CC (44%) and HCC (36%) cohorts, with primary sclerosing cholangitis in the CC (16%) cohort. OS rates at 1, 3 and 5 years for HCC-CC (82%, 47%, 40%) were similar to CC (79%, 58%, 47%), but significantly worse than HCC (86%, 72%, and 62% p = 0.002). Patients undergoing LT for HCC had significantly better survival compared to those transplanted for HCC-CC and CC. LT for mixed HCC-CC confers a survival rate similar to selected patients with CC. Efforts should be made to identify HCC-CC patients preoperatively. Copyright © 2015. Published by Elsevier Ltd.

2016-01-01

The effect of the microalgae Chlorella vulgaris on a wide range of different pesticides in water was studied. Treatments included short-term exposure (1 h) to living and dead microalgal biomass and long-term exposure (4 days) to actively growing microalgae. The initial pesticide concentration was 63.5 ± 3.9 µg L(-1). There was no significant overall reduction of pesticides after short-term exposure. A significant reduction of the total amount of pesticides was achieved after the long-term exposure to growing microalgae (final concentration 29.7 ± 1.0 µg L(-1)) compared with the long-term control (37.0 ± 1.2 µg L(-1)). The concentrations of 10 pesticides out of 38 tested were significantly lowered in the long-term algal treatment. A high impact of abiotic factors such as sunlight and aeration for pesticide reduction was observed when the initial control (63.5 ± 3.9 µg L(-1)) and the long-term control (37.0 ± 1.2 µg L(-1)) were compared. The results suggest that water treatment using microalgae, natural inhabitants of polluted surface waters, could be further explored not only for removal of inorganic nutrients but also for removal of organic pollutants in water.

Pragmatic prevention, permanent solution: Women's experiences with hysterectomy in rural India.

2016-02-01

Hysterectomy appears to be on the rise amongst low-income, rural women in India as routine treatment for gynaecological ailments. This paper explores the individual, household, socio-economic and health system factors that influenced women's decisions to undergo hysterectomy in rural Gujarat, with a focus on women's perspectives. Interviews were conducted with 35 rural, low-income women who had undergone hysterectomy, local gynaecologists and other key informants, alongside observation of daily life and health-related activities. Inductive, open coding was conducted within a framework analysis to identify thematic influences on the decision to undergo hysterectomy. Women underwent hysterectomy at an average age of 36, as treatment for typically severe gynaecological ailments. I argue that women, faced with embedded social inequality in the form of gender biases, lack of labour security and a maternal-centric health system, demonstrated pragmatic agency in their decision to remove the uterus. When they experienced gynaecological ailments, most sought two to three opinions and negotiated financial and logistical concerns. The health system offered few non-invasive services for non-maternal health issues. Moreover, women and health care providers believed there is limited utility of the uterus beyond childbearing. Women's responsibilities as caretakers, workers and producers drove them to seek permanent solutions that would secure their long-term work and health security. Thus, hysterectomy emerged as a normalised treatment for gynaecological ailments, particularly for low-income women with limited resources or awareness of potential side effects. In this setting, hysterectomy reflects the power structures and social inequalities in which women negotiated medical treatment--and the need to reverse a culture of permanent solutions for low-income women.

Many efforts have been made to detect local relapse (LR) in the follow-up after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC) although limited data are available on its treatment and prognosis. We aimed to characterize treatment options and clarify long-term outcomes of isolated LR after SBRT for patients with clinical stage I NSCLC. We reviewed our institutional database in search of patients with isolated LR after SBRT for clinical stage I NSCLC at our institution between 1999 and 2013. Patient characteristics were compared with Mann-Whitney U test, χ2 test, or Fisher's exact test as appropriate. Survival outcomes were estimated with Kaplan-Meier method. Potential prognostic factors were investigated using Cox proportional hazard model. Of 308 patients undergoing SBRT for clinical stage I NSCLC, 49 patients were identified to have isolated LR. Twelve patients underwent salvage surgery, none underwent radiotherapy, and eight patients received chemotherapy, whereas 29 patients received best supportive care. No patient characteristic except operability was significantly related with patient selection for LR treatments. Five-year overall survival (OS) rate of the whole cohort was 47.9% from SBRT and 25.7% from LR. Salvage surgery was associated with improved OS after LR (p = 0.014), and 5-year OS for patients undergoing salvage surgery was 79.5% from LR. It was confirmed that our patient selection for salvage surgery for isolated LR was associated with favorable survival outcomes. Operability based on multidisciplinary conferences, rather than measurable patient characteristics, is essential for appropriate patient selection for salvage surgery.

The Latest in Surgical Management of Stage IIIA Non-Small Cell Lung Cancer: Video-Assisted Thoracic Surgery and Tumor Molecular Profiling.

Woodard, Gavitt A; Jablons, David M

2015-01-01

Stage IIIA non-small cell lung cancer (NSCLC) remains a treatment challenge and requires a multidisciplinary care team to optimize survival outcomes. Thoracic surgeons play an important role in selecting operative candidates and assisting with pathologic mediastinal staging via cervical mediastinoscopy, endobronchial ultrasound, or esophageal ultrasound with fine needle aspiration. The majority of patients with stage IIIA disease will receive induction therapy followed by repeat staging before undergoing lobectomy or pneumonectomy; occasionally, a patient with an incidentally found, single-station microscopic IIIA tumor will undergo resection as the primary initial therapy. Multiple large clinical trials, including SWOG-8805, EORTC-8941, INT-0139, and ANITA, have shown 5-year overall survival rates of up to 30% to 40% using triple-modality treatments, and the best outcomes repeatedly are seen among patients who respond to induction treatment or who have tumors amenable to lobectomy instead of pneumonectomy. The need for a pneumonectomy is not a reason to deny patients an operation, because current operative mortality and morbidity rates are acceptably low at 5% and 30%, respectively. In select patients with stage IIIA disease, video-assisted thoracic surgery and open resections have been shown to have comparable rates of local recurrence and long-term survival. New developments in genetic profiling and personalized medicine are exciting areas of research, and early data suggest that molecular profiling of stage IIIA NSCLC tumors can accurately stratify patients by risk within this stage and predict survival outcomes. Future advances in treating stage IIIA disease will involve developing better systemic therapies and customizing treatment plans on the basis of an individual tumor's genetic profile.

Inhibition of protein synthesis but not β-adrenergic receptors blocks reconsolidation of a cocaine-associated cue memory

Previously consolidated memories have the potential to enter a state of lability upon memory recall, during which time the memory can be altered before undergoing an additional consolidation-like process and being stored again as a long-term memory. Blocking reconsolidation of aberrant memories has been proposed as a potential treatment for psychiatric disorders including addiction. Here we investigated of the effect of systemically administering the protein synthesis inhibitor cycloheximide or the β-adrenergic antagonist propranolol on reconsolidation. Rats were trained to self-administer cocaine, during which each lever press resulted in the presentation of a cue paired with an intravenous infusion of cocaine. After undergoing lever press extinction to reduce operant responding, the cue memory was reactivated and rats were administered systemic injections of propranolol, cycloheximide, or vehicle. Post-reactivation cycloheximide, but not propranolol, resulted in a reactivation-dependent decrease in cue-induced reinstatement, indicative of reconsolidation blockade by protein synthesis inhibition. The present data indicate that systemically targeting protein synthesis as opposed to the β-adrenergic system may more effectively attenuate the reconsolidation of a drug-related memory and decrease drug-seeking behavior.

The prevalence of obesity, defined as a body mass index of 30 or more, has reached epidemic proportions in the United States. Obesity is associated with an increased risk of multiple conditions, including type 2 diabetes mellitus, cardiovascular disease, arthritis, and sleep apnea. To discuss issues related to obesity in the workplace, healthcare, and managed care settings, stakeholders from these areas participated in a roundtable discussion on several topics, including the management of obesity, managed care coverage policies for obesity treatments, and potential strategies for improving patient outcomes. Participants agreed that obesity is a challenging condition to treat. Lifestyle modification, one of the most commonly recommended treatment modalities, is often inadequate on its own, as patients are unable to maintain weight loss over time. Although lifestyle modification remains important, additional tools are needed. In patients who undergo bariatric surgery, lifestyle modification is also necessary for long-term weight maintenance; however, surgery is not appropriate for all patients. Pharmacologic treatment may also be considered, but cost and managed care coverage policies have the potential to limit patient access to this treatment modality. Increased awareness and additional efforts on the part of all stakeholders are needed to improve outcomes for patients affected by obesity.

Long-term efficacy of reverse pull headgear therapy.

2006-11-01

To add to the data for long-term reverse pull headgear (RPHG) outcomes and further explore possible variables that could be predictors of long-term failure. Cephalometric radiographs of 41 Class III malocclusion children treated with RPHG (face mask) were evaluated before and immediately after treatment; at 5 years posttreatment; and, for 18 patients, at 10 years posttreatment. Patients were assigned to success or failure groups according to positive or negative overjet at the longest available recall. Seventy-five percent of the patients maintained positive overjet, whereas 25% outgrew the correction. In a stepwise discriminant analysis, a large mandible and vertical positioning of the maxilla and mandible so that mandibular growth would be projected more horizontally were the major indicators of unfavorable later mandibular growth. Patients who experienced downward-backward rotation of the mandible during RPHG treatment were more likely to be categorized in the failure group. The age at which treatment began had no effect on long-term success and failure for patients younger than 10 years, but the percentage of successful treatment decreased after that age. When RPHG treatment is used for all but the most obviously prognathic children to correct anterior cross-bite in the early mixed dentition, positive overjet is maintained long-term in 70%-75% of cases, whereas 25%-30% of cases relapse into reverse overjet mainly because of increased horizontally directed and often late mandibular growth. Up to age 10, the time at which RPHG treatment began does not appear to be a major factor in long-term success in maintaining positive overjet.

Abstract Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor is the cornerstone of pharmacologic management of patients with acute coronary syndrome (ACS) and/or those receiving coronary stents. Long-term (>1 year) DAPT may further reduce the risk of stent thrombosis after a percutaneous coronary intervention (PCI) and may decrease the occurrence of non-stent-related ischaemic events in patients with ACS. Nevertheless, compared with aspirin alone, extended use of aspirin plus a P2Y12 receptor inhibitor may increase the risk of bleeding events that have been strongly linked to adverse outcomes including recurrent ischaemia, repeat hospitalisation and death. In the past years, multiple randomised trials have been published comparing the duration of DAPT after PCI and in ACS patients, investigating either a shorter or prolonged DAPT regimen. Although the current European Society of Cardiology guidelines provide a backup to individualised treatment, it appears to be difficult to identify the ideal patient profile which could safely reduce or prolong the DAPT duration in daily clinical practice. The aim of this consensus document is to review contemporary literature on optimal DAPT duration, and to guide clinicians in tailoring antiplatelet strategies in patients undergoing PCI or presenting with ACS.

Management of complications related to central venous catheters in cancer patients: an update.

PubMed

Linnemann, Birgit

2014-04-01

Central venous catheters (CVCs) are important for the treatment of patients with cancer, especially in the perioperative and palliative care settings. These devices not only allow for the administration of chemotherapy, parenteral nutrition, and other intravenous therapies, but they may also improve the patients' quality of life by reducing the need for repeated peripheral venipunctures. Thrombotic and infectious complications are common, especially in the long-term use of CVCs. There are different types of thrombotic complications associated with CVCs, that is, a thrombotic occlusion of the catheter, a mural thrombus at the catheter tip and classical deep vein thrombosis, which occurs most frequently in the upper extremity where the majority of long-term catheters are inserted. Infections are common complications associated with CVCs. Patients with cancer who receive intensive chemotherapy and those patients who undergo hematopoietic stem cell transplantation have a markedly increased risk for insertion site and bloodstream infections. In this review, the epidemiology and risk factors that predispose patients to CVC-related thrombosis and infection are discussed. The diagnostic and therapeutic options according to the published data and the current guidelines are summarized and data for establishing primary and secondary preventative strategies are provided.

Long-term topical treatment is often required for atopic dermatitis (AD), a chronic inflammatory skin disease. To assess the long-term safety results from a multicenter, open-label, 48-week safety study (AD-303) of patients (N = 517) ≥2 years of age with mild to moderate AD who continued crisaborole treatment, a topical phosphodiesterase-4 inhibitor, after completing a 28-day phase 3 pivotal study (AD-301, AD-302). Global disease severity was assessed in patients every 4 weeks, and if assessed as mild or greater, a 28-day treatment period with crisaborole applied twice daily was initiated. Adverse events (AEs), including treatment-emergent AEs (TEAEs), and serious AEs were analyzed. During the pivotal studies and AD-303, 65% of patients reported ≥1 TEAE, most of which were mild (51.2%) or moderate (44.6%) and considered unrelated to treatment (93.1%). The frequency and severity of TEAEs were consistent. The most frequently reported treatment-related AEs (overall, 10.2%) were dermatitis atopic (3.1%), application-site pain (2.3%), and application-site infection (1.2%). Nine patients (1.7%) discontinued the long-term study because of TEAEs. Long-term efficacy was not analyzed. Crisaborole ointment had a low frequency of treatment-related AEs over 48 weeks of treatment of patients with AD. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Breast Cancer Survivorship: A Comprehensive Review of Long-Term Medical Issues and Lifestyle Recommendations

Bodai, Balazs I; Tuso, Phillip

2015-01-01

Long-term survival rates after a diagnosis of breast cancer are steadily rising. This is good news, but clinicians must also recognize that this brings new challenges to the medical community. As breast cancer becomes a chronic condition rather than a life-threatening illness owing to advances in early diagnosis and more effective treatments, health care practitioners must recognize and manage the long-term sequelae of the constellation of therapeutic modalities. Survivors of breast cancer represent a unique and extremely complex group of patients; not only do they have the challenge of dealing with multiple long-term side effects of treatment protocols, but many are also forced to address the preexisting comorbidities of their therapies, which often include multiple other issues. Therapies have additional and/or additive side effects that may interfere with treatments directed toward the new primary diagnosis of breast cancer. Our mandate is to establish a smooth transition from patient with breast cancer to survivor of breast cancer while providing ongoing and future guidance. Certainly, the information and resources to accomplish this transition are readily available; however, they are scattered throughout the literature and therefore are not easily accessible or available to the primary care physician. It is imperative that the information available regarding survivorship issues be accessible in an organized and useful format. This article is a modest attempt to provide a comprehensive review of the long-term medical issues relevant to survivorship after the diagnosis and treatment of breast cancer. A predicted shortage of oncologists by 2020 is well-recognized. Therefore, the bulk of long-term care will become dependent on the primary care physician. This shift of care means that these physicians will need to be well educated in the long-term medical issues related to breast cancer treatment. PMID:25902343

Brain size and neuropsychological functioning in long-term survivors of pediatric acute lymphoblastic leukemia.

With the increased survival of pediatric cancer patients the interest in the late effects of treatments is rapidly increasing. Long-term survival rates for children with acute lymphoblastic leukemia (ALL) now approach 90%. Treatment for ALL includes intensified central nervous system (CNS)-directed therapy, which is associated with risks for long-term neurocognitive effects. It is becoming clear that current therapies can have not only a detrimental effect on IQ, processing speed, and memory, but also on structural changes that lead to permanent alterations of the organization of the CNS. Understanding how the CNS is affected by the treatments is a critical step in evaluating current therapies and developing interventions to decrease the incidence and severity of long-term changes in brain anatomy and function.

Malnutrition as assessed with the use of body-composition measurements is a poorly understood short- and long-term complication of childhood cancer. We aimed to evaluate the body composition of 2 childhood cancer cohorts as follows: 1) children currently undergoing cancer treatment and 2) childhood cancer survivors. We also aimed to compare the prevalence of obesity and undernutrition between the cancer groups and investigate the impact of cancer type on body composition. Eighty-two children during the treatment of cancer and 53 childhood cancer survivors were involved in the study. Height, weight, body cell mass, percentage of fat, fat mass index, and fat-free mass index were assessed. Subjects were compared with age- and sex-matched healthy controls. The on-treatment group had a higher percentage of fat (P = 0.0001) and fat mass index (P = 0.0001) and a significantly lower body cell mass index (P = 0.0001) and fat-free mass index (P = 0.003) than did matched controls. The survivor group had a significantly higher percentage of fat (P = 0.03) and fat mass index (P = 0.04) and significantly lower body cell mass index (P = 0.0001) than did matched controls. The prevalence of undernutrition was high in both groups with 48% (95% CI: 36%, 60%) of the on-treatment group and 53% (95% CI: 40%, 66%) of the survivors considered undernourished. According to the percentage of fat cutoffs, significantly more on-treatment patients were obese (55%; 95% CI: 40%, 60%) than were survivors (26%; 95% CI: 14%, 38%) (P = 0.005). There were no statistically significant differences in body composition between cancer types in either the on-treatment or the survivor group. Overnutrition and undernutrition are major concerns in the short and long term for children with cancer. Children treated for cancer have increased fat mass and decreased body cell mass, which are evident during treatment and in survivorship.

The purpose of this paper is to study long-term oncologic outcomes after different treatment strategies for anal canal cancer (SCAC). Patients with SCAC (2004-2013) were identified from Surveillance, Epidemiology, and End Results (SEER) database. Patients undergoing radiation (RT) were compared to those undergoing local excision (LE), abdominoperineal resection (APR), and abdominoperineal resection after radiation (RT + APR). Overall survival (OS) and cancer-specific survival (CSS) data were evaluated using Kaplan-Meier and Cox regression. Two thousand seven hundred and seventy-two (83.8%) patients underwent RT, 382 (11.6%) LE, 77 (2.3%) APR, 76 (2.3%) RT + APR. Median age for the four groups was 60, 57, 64, and 56 years and 32, 49.7, 53.2, and 39.5% were male, respectively, while median tumor size was 4.4, 2.6, 5.3, and 5.5 cm, respectively. Five-year OS of RT, LE, APR, and RT + APR groups was 63.7, 79.6, 25.8, and 41.8% while CSS was 79.6, 92.5, 75.6, and 58.8%, respectively, (p < 0.001). Adjusted hazard ratios for OS for LE, APR, and RT + APR with RT as reference were 1.007 (0.702-1.444), 2.311 (1.367-3.906), and 2.072 (1.016-4.228), respectively. These data suggest that APR does not provide better outcomes in treatment of SCAC. Chemoradiation remains the gold standard treatment for majority of patients. Local excision is associated with favorable outcomes in some circumstances.

Etanercept provides an effective, safe and flexible short- and long-term treatment regimen for moderate-to-severe psoriasis: a systematic review of current evidence.

The treatment of psoriasis requires long-lasting intervention. Conventional treatments for psoriasis comprise topical, phototherapeutic and systemic modalities, such as methotrexate or cyclosporine. Biological therapies are advocated by treatment guidelines for the use in moderate-to-severe psoriasis, when conventional treatments have failed, are contraindicated or are associated with severe adverse events. Etanercept is an anti-TNF recombinant fusion protein that has emerged as a standard biologic treatment option for moderate-to-severe psoriasis. The present review summarizes data from pivotal and post-marketing randomized controlled etanercept trials to treat moderate-to-severe psoriasis for 24 weeks and longer. During the first 12 weeks, etanercept can be administered in different dosing regimens: 50 mg twice weekly (BIW) and 50 mg once weekly. Although both regimens are effective, it has been shown that the 50 mg BIW dosage leads to higher response rates at week 24. In addition, after 24 weeks' treatment etanercept provides the unique possibility of continuous or intermittent long-term treatment programmes. The medium- to long-term efficacy of etanercept was consistent, regardless of whether etanercept therapy was interrupted or continuous. Taking the chronic nature of psoriasis into account, this flexibility in dosing regimen bestows a key advantage in facilitating individualisation of long-term treatment according to patient needs.

To evaluate the long-term effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Twenty-three Class II patients (8 male, 15 female) were treated consecutively with the Balters bionator (bionator group). The sample was evaluated at T0, start of treatment; T1, end of bionator therapy; and T2, long-term observation (including fixed appliances). Mean age at the start of treatment was 10 years 2 months (T0); at posttreatment, 12 years 3 months (T1); and at long-term follow-up, 18 years 2 months (T2). The control group consisted of 22 subjects (11 male, 11 female) with untreated Class II malocclusion. Lateral cephalograms were analyzed at the three time points for all groups. TPS analysis evaluated statistical differences (permutation tests) in the craniofacial shape and size between the bionator and control groups. TPS analysis showed that treatment with the bionator is able to produce favorable mandibular shape changes (forward and downward displacement) that contribute significantly to the correction of the Class II dentoskeletal imbalance. These results are maintained at a long-term observation after completion of growth. The control group showed no statistically significant differences in the correction of Class II malocclusion. This study suggests that bionator treatment of Class II malocclusion produces favorable results over the long term with a combination of skeletal and dentoalveolar shape changes.

To compare the long-term self-esteem and social function outcomes of individuals with untreated and treated ADHD across childhood, adolescence, and adulthood. A systematic search of 12 databases was performed to identify peer-reviewed, primary research articles, published January 1980 to December 2011, reporting long-term self-esteem and/or social function outcomes (≥2 years; life consequences distinct from symptoms) of individuals with untreated or treated ADHD. Overall, 127 studies reported 150 outcomes. Most outcomes were poorer in individuals with untreated ADHD versus non-ADHD controls (57% [13/23] for self-esteem; 73% [52/71] for social function). A beneficial response to treatment (pharmacological, nonpharmacological, and multimodal treatments) was reported for the majority of self-esteem (89% [8/9]) and social function (77% [17/22]) outcomes. Untreated ADHD was associated with poorer long-term self-esteem and social function outcomes compared with non-ADHD controls. Treatment for ADHD was associated with improvement in outcomes; however, further long-term outcome studies are needed. © The Author(s) 2013.

Nonsurgical Outpatient Therapies for the Management of Female Stress Urinary Incontinence: Long-Term Effectiveness and Durability

PubMed Central

Davila, G. Willy

2011-01-01

Objective. To evaluate long-term effectiveness and safety of conservative and minimally invasive outpatient treatments for female stress urinary incontinence (SUI) through a review of the literature. Methods. PubMed was searched for reports on prospective clinical trials with at least 12-month follow-up of minimally invasive treatments, pelvic floor rehabilitation, or pharmacotherapy in women with SUI. Each report was examined for long-term rates of effectiveness and safety. Results. Thirty-two clinical trial reports were included. Prospective long-term studies of pelvic floor rehabilitation were limited but indicated significant improvements with treatment adherence for at least 12 months. Poor initial tolerability with duloxetine resulted in substantial discontinuation. Most patients receiving transurethral radiofrequency collagen denaturation or urethral bulking agents reported significant long-term improvements, generally good tolerability, and safety. Conclusions. Conservative therapy is an appropriate initial approach for female SUI, but if therapy fails, radiofrequency collagen denaturation or bulking agents may be an attractive intermediate management step or alternative to surgery.

State of the art treatments for cannabis dependence.

PubMed

Danovitch, Itai; Gorelick, David A

2012-06-01

The treatment of cannabis dependence can be viewed as a cup half empty or half full. On the one hand, few people who might benefit from treatment actually receive it. Among those who undergo treatment in randomized trials, long-term abstinence is achieved by fewer than 20%. Moderate use goals have been associated with decreases in consequences, but the differential impact of such goals on the long-term course of cannabis dependence is unknown. Optimal duration of treatment is unclear, and certain populations, particularly patients with co-occurring disorders, have not been studied adequately. Twelve-step programs are low cost, effective for other substance use disorders, and readily available in most regions of the world. However, their role and efficacy in cannabis dependence has not been examined. Finally, effective pharmacologic treatments are under development, but none have yet been firmly established. On the other hand, psychotherapeutic strategies used to treat other substance use disorders can be effective for cannabis dependence. A recent meta-analysis of psychosocial interventions for illicit substance use disorders found that treatments for cannabis dependence had comparatively larger effect sizes than treatments for other substance use disorders. Combination therapies have proven most effective, particularly those that begin with a motivational intervention, utilize incentives to enhance the commitment to change, and teach behavioral and cognitive copings skills to prevent relapse. Among adolescents, family engagement and collaboration with community stakeholders adds substantial value. Although only 9% of cannabis users develop cannabis dependence, the volume of people who smoke cannabis ensures that the total number of people in need of help is larger than the capacity of substance abuse specialty services. Thus, although efforts to refine and improve the efficacy of treatment interventions continue, innovations that increase the availability and accessibility of treatment are also needed. Computer- and phone-based interventions, social media, and brief interventions that can be implemented in primary care settings are areas that may hold promise for reaching at-risk populations. Adolescents and persons with co-occurring mental illness are at particularly high risk of cannabis dependence, and may suffer disproportionately from cannabis’s adverse effects. As in the treatment of other substance use disorders, there is a need for a continuing care model with long-term follow-up that extends past the periods typically evaluated in treatment studies. Additionally, there is a need for further investigation of genetic underpinnings and endophenotypes underlying cannabis dependence to identify neurobiological mechanisms for targeted intervention. One benefit of the societal focus on cannabis has been a prominent increase in research covering everything from the basic science to public health impact of cannabis. Over the next decade, physicians who provide treatment for individuals with cannabis dependence are likely to see their armamentarium of effective interventions expand, to the ultimate betterment of patients, their families, and society at large.

The impacts of manure application on soil ammonia (NH 3 ) volatilization and greenhouse gas (GHG) emissions are of interest for both agronomic and environmental reasons. However, how the swine manure addition affects greenhouse gas and N emissions in North China Plain wheat fields is still unknown. A long-term fertilization experiment was carried out on a maize-wheat rotation system in Northern China (Zea mays L-Triticum aestivum L.) from 1990 to 2017. The experiment included four treatments: (1) No fertilizer (CK), (2) single application of chemical fertilizers (NPK), (3) NPK plus 22.5t/ha swine manure (NPKM), (4) NPK plus 33.7t/ha swine manure (NPKM+). A short-term fertilization experiment was conducted from 2016 to 2017 using the same treatments in a field that had been abandoned for decades. The emissions of NH 3 and GHGs were measured during the wheat season from 2016 to 2017. Results showed that after long-term fertilization the wheat yields for NPKM treatment were 7105kg/ha, which were higher than NPK (3880kg/ha) and NPKM+ treatments (5518kg/ha). The wheat yields were similar after short-term fertilization (6098-6887kg/ha). The NH 3 -N emission factors (EF amm ) for NPKM and NPKM+ treatments (1.1 and 1.1-1.4%, respectively) were lower than NPK treatment (2.2%) in both the long and short-term fertilization treatments. In the long- and short-term experiments the nitrous oxide (N 2 O) emission factors (EF nit ) for NPKM+ treatment were 4.2% and 3.7%, respectively, which were higher than for the NPK treatment (3.5% and 2.5%, respectively) and the NPKM treatment (3.6% and 2.2%, respectively). In addition, under long and short-term fertilization, the greenhouse gas intensities for the NPKM+ treatment were 33.7 and 27.0kg CO 2 -eq/kg yield, respectively, which were higher than for the NPKM treatment (22.8 and 21.1kg CO 2 -eq/kg yield, respectively). These results imply that excessive swine manure application does not increase yield but increases GHG emissions. Copyright © 2018 Elsevier B.V. All rights reserved.

Objective: This secondary data analysis examined patterns of drinking during alcohol treatment and associated drinking outcomes during the first year following treatment. The goal was to provide clinicians with guidance on which patients may be most at risk for negative long-term outcomes based on drinking patterns during treatment. Method: This study was an analysis of existing data (N = 3,851) from three randomized clinical trials for alcohol use disorder: the COMBINE Study (n = 1,383), Project MATCH (n = 1,726), and the United Kingdom Alcohol Treatment Trial (n = 742). Indicators of abstinence, non-heavy drinking, and heavy drinking (defined as 4/5 or more drinks per day for women/men) were examined during each week of treatment using repeated-measures latent class analysis. Associations between drinking patterns during treatment and drinking intensity, drinking consequences, and physical and mental health 12 months following intake were examined. Results: Seven drinking patterns were identified. Patients who engaged in persistent heavy drinking throughout treatment and those who returned to persistent heavy drinking during treatment had the worst long-term outcomes. Patients who engaged in some heavy drinking during treatment had better long-term outcomes than persistent heavy drinkers. Patients who reported low-risk drinking or abstinence had the best long-term outcomes. There were no differences in outcomes between low-risk drinkers and abstainers. Conclusions: Abstinence, low-risk drinking, or even some heavy drinking during treatment are associated with the best long-term outcomes. Patients who are engaging in persistent heavy drinking are likely to have the worst outcomes and may require a higher level of care. PMID:27936365

To compare the long-term survival of patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) undergoing either liver resection or transarterial chemoembolization (TACE) after propensity score matching (PSM). One hundred sixty-seven and 70 BCLC-B HCC patients undergoing liver resection and TACE were retrospectively collected. PSM function of SPSS software was conducted to reduce confounding bias between the groups. And then survival analysis was performed for the matched data. Fifty-three pairs of patients were successfully matched. And then survival analysis showed that the median survival periods and their 95% confidence intervals were 35.0 (26.3-43.7)months in the liver resection group versus 20.0(15.0-25.0) months in the TACE group. The 1, 3, 5 and 7-year survival rates were 91.0%, 49.0%, 30.0% and 17.0% in the liver resection group versus 73.0%, 25.0%, 8.0% and 5.0% respectively in the TACE group (P = 0.001). Cox regression analysis revealed that TACE, total bilirubin ≥ 34.2 µmol/L, alpha fetoprotein ≥ 400 ng/ml and tumor number ≥ 3 were independent risk factors of survival (hazard ratio >1, P < 0.05). The balance of covariates may be achieved through PSM. And for patients with BCLC-B HCC, liver resection provides better long-term overall survival than TACE.

OBJECTIVE Aneurysmal rebleeding before definitive obliteration of the aneurysm is a cause of mortality and morbidity. There are limited data on the role of short-term antifibrinolytic therapy among patients undergoing endovascular intervention. METHODS All consecutive patients receiving endovascular therapy for their ruptured saccular aneurysm at the authors' institution between 2000 and 2011 were included in this study. These patients underwent endovascular coiling of their aneurysm within 72 hours of admission. In patients receiving ε-aminocaproic acid (EACA), the EACA administration was continued until the time of the endovascular procedure. Complications and clinical outcomes of endovascular treatment after aneurysmal subarachnoid hemorrhage (aSAH) were compared between EACA-treated and untreated patients. RESULTS During the 12-year study period, 341 patients underwent endovascular coiling. Short-term EACA treatment was administered in 146 patients and was withheld in the other 195 patients. EACA treatment did not change the risk of preinterventional rebleeding in this study (OR 0.782, 95% CI 0.176-3.480; p = 0.747). Moreover, EACA treatment did not increase the rate of thromboembolic events. On the other hand, patients who received EACA treatment had a significantly longer duration of hospital stay compared with their counterparts who were not treated with EACA (median 19 days, interquartile range [IQR] 12.5-30 days vs median 14 days, IQR 10-23 days; p < 0.001). EACA treatment was associated with increased odds of shunt requirement (OR 2.047, 95% CI 1.043-4.018; p = 0.037) and decreased odds of developing cardiac complications (OR 0.138, 95% CI 0.031-0.604; p = 0.009) and respiratory insufficiency (OR 0.471, 95% CI 0.239-0.926; p = 0.029). Short-term EACA treatment did not affect the Glasgow Outcome Scale score at discharge, 6 months, or 1 year following discharge. CONCLUSIONS In this study, short-term EACA treatment in patients who suffered from aSAH and received endovascular aneurysm repair did not decrease the risk of preinterventional rebleeding or increase the risk of thrombotic events. EACA did not affect outcome. Randomized clinical trials are required to provide robust clinical recommendation on short-term use of EACA.

To assess the short-term and long-term effects of dipeptidyl peptidase-4 (DPP-4) inhibitors in type 2 diabetes mellitus patients with renal impairment, a meta-analysis of randomized clinical trials of DPP-4 inhibitor interventions in type 2 diabetes mellitus patients with renal impairment was performed. PubMed, Embase, Cochrane Library and ClinicalTrials.gov were searched through the end of March 2015. Randomized clinical trials were selected if (1) DPP-4 inhibitors were compared with a placebo or other active-comparators, (2) the treatment duration was ≥12 weeks and (3) data regarding changes in haemoglobin A1c (HbA1c ), changes in fasting plasma glucose or hypoglycaemia and other adverse events were reported. Of 790 studies, ten studies on eight randomized clinical trials were included. Compared with the control group, DPP-4 inhibitors were associated with a greater HbA1c reduction in both the short-term [mean differences (MD) = -0.45, 95% confidence intervals (-0.57, -0.33), p < 0.0001] and long-term [MD = -0.33, 95% confidence intervals (-0.63, -0.03), p = 0.03] treatments. However, the long-term greater reduction in HbA1c with DPP-4 inhibitor treatment was only significant when the control treatment comprised placebo plus stable background treatment, but not glipizide plus stable background treatment. DPP-4 inhibitors were associated with a greater fasting plasma glucose reduction [MD = -12.59, 95% confidence intervals (-22.01, -3.17), p = 0.009] over the short-term; however, this effect was not present over the long-term. Regarding the hypoglycaemia adverse events assessment, the long-term treatment data indicated there was no increased risk of hypoglycaemia compared with placebo or active-controlled anti-diabetic drugs. The present meta-analysis confirms that DPP-4 inhibitors are effective and equivalent to other agents in type 2 diabetes mellitus patients with renal impairment.

The only cells of the hematopoietic system that undergo self-renewal for the lifetime of the organism are long-term hematopoietic stem cells and memory T and B cells. To determine whether there is a shared transcriptional program among these self-renewing populations, we first compared the gene-expression profiles of naïve, effector and memory CD8+ T cells with those of long-term hematopoietic stem cells, short-term hematopoietic stem cells, and lineage-committed progenitors. Transcripts augmented in memory CD8+ T cells relative to naïve and effector T cells were selectively enriched in long-term hematopoietic stem cells and were progressively lost in their short-term and lineage-committed counterparts. Furthermore, transcripts selectively decreased in memory CD8+ T cells were selectively down-regulated in long-term hematopoietic stem cells and progressively increased with differentiation. To confirm that this pattern was a general property of immunologic memory, we turned to independently generated gene expression profiles of memory, naïve, germinal center, and plasma B cells. Once again, memory-enriched and -depleted transcripts were also appropriately augmented and diminished in long-term hematopoietic stem cells, and their expression correlated with progressive loss of self-renewal function. Thus, there appears to be a common signature of both up- and down-regulated transcripts shared between memory T cells, memory B cells, and long-term hematopoietic stem cells. This signature was not consistently enriched in neural or embryonic stem cell populations and, therefore, appears to be restricted to the hematopoeitic system. These observations provide evidence that the shared phenotype of self-renewal in the hematopoietic system is linked at the molecular level. PMID:16492737

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.

The study showed that on a sheltered vegetable field, a long-term application of organic plus chemical fertilizers induced a higher content of loosely combined soil humus than applying chemical fertilizers alone, while there was no significant difference in firmly combined humus content among different fertilization treatments. More tightly combined humus was observed in organic fertilizer treatments than in chemical fertilizer treatments, and the highest content (11.53 g x kg(-1)) was in the treatment of organic fertilizer plus chemical NPK. The ratio of loosely/tightly combined humus tended to decrease after a long-term application of organic fertilizer, being the lowest (1.10) in the treatment of organic fertilizer plus chemical NPK.

The management of patients with limited-stage classical Hodgkin lymphoma.

Gospodarowicz, Mary K; Meyer, Ralph M

2006-01-01

The term limited-stage Hodgkin lymphoma refers to those patients with stage I-II disease and an absence of bulky disease. Among those patients with classical Hodgkin lymphoma, approximately one-third of patients will fall into this category. As long-term disease control can now be anticipated in more than 90% of these patients, management strategies must increasingly address the need to reduce the long-term treatment-related risks. Current treatment options include use of combined modality therapy that includes an abbreviated course of chemotherapy and involved-field radiation or treatment with chemotherapy, currently consisting of ABVD, as a single modality. The choice of treatment between these two options involves specific trade-offs that must balance issues of disease control against long-term risk of late effects.

The relationship between stress and Alzheimer's disease.

Justice, Nicholas J

2018-02-01

Stress is critically involved in the development and progression of disease. From the stress of undergoing treatments to facing your own mortality, the physiological processes that stress drives have a serious detrimental effect on the ability to heal, cope and maintain a positive quality of life. This is becoming increasingly clear in the case of neurodegenerative diseases. Neurodegenerative diseases involve the devastating loss of cognitive and motor function which is stressful in itself, but can also disrupt neural circuits that mediate stress responses. Disrupting these circuits produces aberrant emotional and aggressive behavior that causes long-term care to be especially difficult. In addition, added stress drives progression of the disease and can exacerbate symptoms. In this review, I describe how neural and endocrine pathways activated by stress interact with ongoing neurodegenerative disease from both a clinical and experimental perspective.

The association between off-hours presentation and mortality in patients with ST-segment elevation myocardial infarction (STEMI) remains unclear. We performed a meta-analysis to assess the impact of off-hours presentation on short- and long-term mortality among STEMI patients. We searched PubMed, EMBASE, and the Cochrane Library from their inception to 10 July 2016. Studies were eligible if they evaluated the relationship of off-hours (weekend and/or night) presentation with short- and/or long-term mortality. A total of 30 studies with 33 cohorts involving 192,658 STEMI patients were included. Off-hours presentation was associated with short-term mortality (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.02-1.12, P = 0.004) but not with long-term mortality (OR 1.00, 95% CI 0.94-1.07, P = 0.979). No significant heterogeneity was observed. The outcomes remained the same after sensitivity analyses and trim and fill analyses. Subgroup analyses showed that STEMI patients undergoing primary percutaneous coronary intervention do not have a higher risk of short-term mortality (OR 1.061, 95% CI 0.993-1.151). In addition, higher mortality was observed only during hospitalization (OR 1.072, 95% CI 1.022-1.125), not at the 30-day, 1-year or long-term follow-ups. Off-hours presentation was associated with an increase in short-term mortality, but not long-term mortality, among STEMI patients. Clinical approaches to decrease short-term mortality regardless of the time of presentation should be evaluated in future studies.

Single-center experiences with the treatment of infected endografts after endovascular aortic repair (I-EVAR) have been reported. We performed a multicenter review of the surgical care of these patients to elucidate short-term and long-term outcomes. A retrospective analysis of all EVAR explants from 1997 to 2014 at four institutions was performed. Patients with I-EVAR undergoing surgical treatment were reviewed. Data were obtained detailing preoperative demographics, and postoperative morbidity and mortality. Thirty-six patients (30 male) were treated with endovascular graft excision and revascularization for I-EVAR with a median age of 69 years (range, 54-80 years). Average time from the initial EVAR to presentation was 589 days (range, 43-2466 days). Preoperative comorbidities included hypertension, 32 (89%); tobacco use, 31(86%); coronary artery disease, 26 (72%); hyperlipidemia, 25 (69%), peripheral artery disease, 13 (36%); cerebrovascular disease, 10 (28%); diabetes, 10 (28%); chronic obstructive pulmonary disease, 9 (25%); and chronic kidney disease, 9 (25%). The most common presenting patient characteristics were leukocytosis, 23 (63%); pain, 21 (58%); and fever, 20 (56%), which were present an average of 65 days (range, 0-514 days) before explantation. Nine different types of endograft were removed. Three patients (8%) underwent emergency explantation. Thirty-four patients (89%) underwent total graft excision, and two patients (6%) underwent partial excision. Methods of reconstruction were in situ in 27 (75%) and extra-anatomic in nine (28%). Conduits used were Dacron (DuPont, Wilmington, Del), with or without rifampin, polytetrafluoroethylene, cryopreserved allograft, and femoral vein. Forty-nine organisms grew from operative cultures. Gram-positive organisms were the most common, found in 24 (67%), including Staphylococcus in 13 (36%) and Streptococcus in six (17%). Anaerobes were cultured in 6 patients (17%), gram-negative organisms in 6 (17%), and fungus in 5 (14%). Thirty-one patients (86%) received long-term antibiotics. Early complications included acute renal failure requiring dialysis, 12 (33%); respiratory failure, 3 (8%); bleeding, 4 (11%); and sepsis, 2 (6%). Six patients required re-exploration due to hematoma, infected hematoma, lymphatic leak, bowel perforation, open abdomen at initial operation, and anastomotic bleeding. Perioperative mortality was 8% (3 of 36), and long-term mortality was 25% (9 of 36) at a mean follow-up of 569 days (range, 0-3079 days). Type of reconstruction (in situ vs extra-anatomic) or conduit type did not affect perioperative or overall mortality. I-EVAR is a rare but potentially devastating clinical problem. Although perioperative mortality is acceptable, long-term mortality is high. The most common postoperative complication was acute renal failure requiring dialysis. Although this is the largest series of I-EVAR, further studies are needed to understand the risk factors and preventive measures. Copyright © 2015 Society for Vascular Surgery.

Experiencing real weightlessness in space is a dream for many of us who are interested in space research. Although space traveling fascinates us, it can cause both short-term and long-term health problems. Microgravity is the most important influence on the human organism in space. The human body undergoes dramatic changes during a long-term spaceflight. In this review, we will mainly focus on changes in calcium, sodium and bone metabolism of space travelers. Moreover, we report on the current knowledge on the mechanisms of bone loss in space, available models to simulate the effects of microgravity on bone on Earth as well as the combined effects of microgravity and cosmic radiation on bone. The available countermeasures applied in space will also be evaluated. Copyright © 2016 Elsevier Inc. All rights reserved.

GLYCEMIC CONTROL AND BURNT-OUT Diabetes IN ESRD

PubMed Central

Kovesdy, Csaba P; Park, J.C.; Kalantar-Zadeh, Kamyar

2017-01-01

Treatment of early diabetes mellitus, the most common cause of chronic kidney disease (CKD), may prevent or slow the progression of diabetic nephropathy and lower mortality and the incidence of cardiovascular disease in the general diabetic population and in patients with early stages of CKD. It is unclear whether glycemic control in patients with advanced CKD, including those with end-stage renal disease (ESRD) who undergo maintenance dialysis treatment is beneficial. Aside from the uncertain benefits of treatment in ESRD, hypoglycemic interventions in this population are also complicated by the complex changes in glucose homeostasis related to decreased kidney function and to dialytic therapies, occasionally leading to spontaneous resolution of hyperglycemia and normalization of hemoglobin A1c levels, a condition which might be termed “burnt-out diabetes”. Further difficulties in ESRD are posed by the complicated pharmacokinetics of antidiabetic medications and the serious flaws in our available diagnostic tools used for monitoring long-term glycemic control. We review the physiology and pathophysiology of glucose homeostasis in advanced CKD and ESRD, the available antidiabetic medications and their specifics related to kidney function, and the diagnostic tools used to monitor the severity of hyperglycemia and the therapeutic effects of available treatments, along with their deficiencies in ESRD. We also review the concept of burnt-out diabetes and summarize the findings of studies that examined outcomes related to glycemic control in diabetic ESRD patients, and emphasize areas in need of further research.

The long-pulsed diode (800-810-nm) laser is one of the most commonly used and effective lasers for hair removal. Limitations of currently available devices include a small treatment spot size, treatment-associated pain, and the need for skin cooling. To evaluate the long-term hair reduction capabilities of a long-pulsed diode laser with a large spot size and vacuum assisted suction. Thirty-five subjects were enrolled in a prospective, self-controlled, single-center study of axillary hair removal. The study consisted of three treatments using a long-pulsed diode laser with a large spot size and vacuum-assisted suction at 4- to 6-week intervals with follow-up visits 6 and 15 months after the last treatment. Hair clearance was quantified using macro hair-count photographs taken at baseline and at 6- and 15-month follow-up visits. Changes in hair thickness and color, levels of treatment-associated pain, and adverse events were additional study endpoints. There was statistically significant hair clearance at the 6 (54%) and 15-month (42%) follow-up visits. Remaining hairs were thinner and lighter at the 15-month follow-up visit, and the majority of subjects reported feeling up to mild to moderate pain during treatment without the use of pretreatment anesthesia or skin cooling. A long-pulsed diode laser with a large spot size and vacuum-assisted suction is safe and effective for long-term hair removal. This is the largest prospective study to evaluate long-term hair removal and the first to quantify decreases in hair thickness and darkness with treatment. © 2012 by the American Society for Dermatologic Surgery, Inc.

Progress in the treatment of advanced medullary thyroid cancer (MTC) has resulted from the approval of 2 drugs within the past 5 years, vandetanib and cabozantinib. These multikinase inhibitors (MKIs) possess overlapping specificities for multiple kinase targets implicated in the progression of MTC. Both drugs are associated with toxicities, including hypertension, hemorrhage/perforation, diarrhea and other gastrointestinal events, several dermatologic events, and hypothyroidism. In addition, vandetanib is uniquely associated with QTc prolongation through interaction with myocardial potassium channels, and cabozantinib is uniquely associated with hand-foot skin reaction. Treatment-related toxicities occur frequently and can be severe or life-threatening, and patients undergoing long-term treatment will likely experience adverse events (AEs). Here we offer specific practical recommendations for managing AEs commonly occurring with vandetanib and cabozantinib. The recommended approach relies on early recognition and palliation of symptoms, dose interruption, and dose reduction as necessary in order for the patient to maintain the highest tolerable dose for as long as possible and optimal quality of life. Treatment guidelines do not specify a recommended sequence for treating with vandetanib and cabozantinib; however, most patients will receive both drugs during their lifetime. The choice for first-line therapy is individualized after a risk-benefit assessment and depends on physician preference and patient-related factors, such as comorbid conditions. Because most generalist practices may not be familiar with the intricacies of agents such as vandetanib and cabozantinib, we commend that patients with advanced MTC be managed and treated by a thyroid cancer specialist with coordination of care within a multidisciplinary team.

Purpose: The goal of this study was to verify the significance of p53 as a prognostic factor in Radiation Therapy Oncology Group 9202, which compared short-term androgen deprivation (STAD) with radiation therapy (RT) to long-term androgen deprivation + RT in men with locally advanced prostate cancer (Pca). Methods and Materials: Tumor tissue was sufficient for p53 analysis in 777 cases. p53 status was determined by immunohistochemistry. Abnormal p53 expression was defined as 20% or more tumor cells with positive nuclei. Univariate and multivariate Cox proportional hazards models were used to evaluate the relationships of p53 status to patient outcomes. Results:more » Abnormal p53 was detected in 168 of 777 (21.6%) cases, and was significantly associated with cause-specific mortality (adjusted hazard ratio [HR] = 1.89; 95% confidence interval (CI) 1.14 - 3.14; p = 0.014) and distant metastasis (adjusted HR = 1.72; 95% CI 1.13-2.62; p = 0.013). When patients were divided into subgroups according to assigned treatment, only the subgroup of patients who underwent STAD + RT showed significant correlation between p53 status and cause-specific mortality (adjusted HR = 2.43; 95% CI = 1.32-4.49; p = 0.0044). When patients were divided into subgroups according to p53 status, only the subgroup of patients with abnormal p53 showed significant association between assigned treatment and cause-specific mortality (adjusted HR = 3.81; 95% CI 1.40-10.37; p = 0.0087). Conclusions: Abnormal p53 is a significant prognostic factor for patients with prostate cancer who undergo short-term androgen deprivation and radiotherapy. Long-term androgen deprivation may significantly improve the cause-specific survival for those with abnormal p53.« less

To test the short term clinical effectiveness of commercially available 0.07%.cetylpyridinium chloride mouth rinse in patients undergoing fixed orthodontic treatment as compared to a placebo mouth rinse and patients using toothbrush and toothpaste. Forty-five subjects for this double blind study were assigned randomly into three groups of 15 each. Gingival inflammation, plaque accumulation, and bleeding on probing, were recorded at baseline (10 days after prophylaxis), and at the end of one month in all the three groups and compared. Paired t test showed significant differences in bleeding index for pre and post treatment recordings for cetylpyridinium group. Modified gingival index showed no significant difference in the cetylpyridinium group. For plaque index significant difference was found for cetylpyridinium and control groups. Cetylpyridinium mouth rinse 0.7% was found to be effective in reducing the bleeding and plaque index scores. It was not effective in reducing the modified gingival index scores. Cetylpyridinium mouth rinse 0.07% improves the oral hygiene of orthodontic patients when used as an adjunct to normal oral hygiene measures.

The initiation of tobacco use occurs most often in adolescence and may be especially detrimental as the adolescent brain is undergoing substantial development. In addition to nicotine, there are over 9000 other compounds present in tobacco products, including the β-carbolines harmane and norharmane. The present study aimed to determine the long-term effects of adolescent exposure to nicotine (NIC), harmane (HAR), or norharmane (NOR) on locomotor activity, learning and memory, anxiety-like behavior, motor coordination, and monoamine/metabolite concentrations in the striatum and nucleus accumbens of male Sprague-Dawley rats. Beginning on postnatal day (PND) 27 and continuing through PND 55, subjects received twice daily intraperitoneal injections of 1ml/kg saline (CON), 0.5mg NIC/kg, 0.5mg HAR/kg, or 0.5mg NOR/kg. Body weight, food, and water intake were measured daily (PNDs 27-96). Locomotor activity was assessed on PND 40 or 41, PND 55, and PNDs 81 and 82. Other behaviors (anxiety-like behavior, motor coordination, and spatial learning and memory) were assessed at least 25 days after drug exposure ended (PNDs 80-91). On PND 97, subjects were decapitated and the striatum and nucleus accumbens were dissected and frozen for analysis. NIC treatment significantly decreased food intake, but did not alter locomotor activity during or after treatment. HAR and NOR treatment, however, caused significant open field hypoactivity. Motor coordination, water maze performance, and concentrations of monoamines and metabolites in the striatum and nucleus accumbens were unaltered by any drug treatment. These results indicate a long-lasting effect on activity levels from adolescent HAR or NOR treatment; however, there were few long-lasting NIC effects. Given the paucity of data describing effects of HAR or NOR exposure, these data should encourage additional studies of these tobacco constituents as well as constituent combination studies.

Decades of fire suppression following extensive timber harvesting have left much of the forest in the intermountain western United States exceedingly dense, and forest restoration techniques (i.e., thinning and prescribed fire) are increasingly being used in an attempt to mitigate the effects of severe wildfire, to enhance tree growth and regeneration, and to stimulate soil nutrient cycling. While many of the short-term effects of forest restoration have been established, the long-term effects on soil biogeochemical and ecosystem processes are largely unknown. We assessed the effects of commonly used forest restoration treatments (thinning, burning, and thinning + burning) on nutrient cycling and other ecosystem processes 11 yr after restoration treatments were implemented in a ponderosa pine (Pinus ponderosa var. scopulorum)/Douglas fir (Pseudotsuga menziesii var. glauca) forest at the Lubrecht Fire and Fire Surrogates Study (FFS) site in western Montana, USA. Despite short-term (<3 yr) increases in soil inorganic nitrogen (N) pools and N cycling rates following prescribed fire, long-term soil N pools and N mineralization rates showed only subtle differences from untreated control plots. Similarly, despite a persistent positive correlation between fuels consumed in prescribed burns and several metrics of N cycling, variability in inorganic N pools decreased significantly since treatments were implemented, indicating a decline in N spatial heterogeneity through time. However, rates of net nitrification remain significantly higher in a thin + burn treatment relative to other treatments. Short-term declines in forest floor carbon (C) pools have persisted in the thin + burn treatment, but there were no significant long-term differences among treatments in extractable soil phosphorus (P). Finally, despite some short-term differences, long-term foliar nutrient concentrations, litter decomposition rates, and rates of free-living N fixation in the experimental plots were not different from control plots, suggesting nutrient cycles and ecosystem processes in temperate coniferous forests are resilient to disturbance following long periods of fire suppression. Overall, this study provides forest managers and policymakers valuable information showing that the effects of these commonly used restoration prescriptions on soil nutrient cycling are ephemeral and that use of repeated treatments (i.e., frequent fire) will be necessary to ensure continued restoration success. © 2016 by the Ecological Society of America.

To evaluate the role of treatment timing on long-term dentoskeletal effects of Class II treatment with removable functional appliances followed by full-fixed appliance therapy. A group of 46 patients (23 females and 23 males) with Class II malocclusion treated consecutively with either Bionator or Activator, followed by fixed appliances was compared with a matched control group of 31 subjects (16 females and 15 males) with untreated Class II malocclusion. The treated sample was evaluated at T1, start of treatment (mean age: 9.9 ± 1.3 years); T2, end of functional treatment and prior to fixed appliances (mean age: 11.9 ± 1.3 years); and T3, long-term observation (mean age: 18.3 ± 2.1 years). The treated and the control samples were divided into pre-pubertal and pubertal groups according to skeletal maturity observed at the start of treatment. Statistical comparisons were performed with independent sample t-tests. When treatment was initiated before puberty, Class II correction was mostly confined to the dentoalveolar changes, with significant improvements of both overjet and molar relationships. On the other hand, treatment with the outset at puberty produced significant long-term improvement of sagittal skeletal relationships, which were mainly sustained by mandibular changes. Treatment with removable functional appliances (Bionator or Activator) followed by full-fixed appliances produced significant skeletal long-term changes when it begins at puberty. Prepubertal Class II treatment results primarily in dentoalveolar changes. © The Author 2017. Published by Oxford University Press on behalf of the European Orthodontic Society. All rights reserved.

To determine the long-term (>3 years) outcome of patients suffering from simple snoring or non-severe obstructive sleep apnea syndrome (OSAS) treated by radiofrequency ablation of the soft palate. Observational retrospective study. Tertiary care university hospital. Seventy-seven subjects were included between 1999 and 2006. Twenty-seven suffered from mild or moderate OSAS. All patients were treated by radiofrequency-assisted stiffening of the soft palate, with or without uvulectomy. Snoring (assessed on a 10 cm visual analog scale (VAS)), marital status, presence of cardiovascular risk factors or pathologies and follow-up time were evaluated by postal questionnaire. Mean follow-up time was 6.3 ± 2.3 years. Mean snoring intensity decreased significantly in the immediate postoperative period (8.1 ± 2.9 to 3.5 ± 2.2 cm on VAS). Over the longer term, however, we observed a significant increase in snoring intensity (5.7 ± 2.9 cm), which nevertheless remained below the preoperative values (P<0.001). Bed-partners noticed a relapse of snoring in 92.7% of cases. Nine percent of couples separated. Hypertension and diabetes were diagnosed during follow-up in 12.1% and 6.6% of the subjects, respectively. A majority of patients failed to undergo repeat polysomnography or further treatment. Relapse of snoring was observed in nearly all patients in the long run, although intensity appears to remain lower than preoperatively. Most patients did not comply with the follow-up instructions and did not seek other forms of treatment when recurrence occurred. Copyright © 2013. Published by Elsevier Masson SAS.

Percutaneous carotid artery stenting (CAS) has emerged as a less invasive alternative to carotid endarterectomy for the treatment of carotid atherosclerotic disease. The main risk of CAS is the occurrence of neuro-vascular complications; however, carotid artery stenting-related dysautonomia (CAS-D) (hypertension, hypotension, and bradycardia) is the most frequently reported problem occurring in the periprocedural period. Alterations in autonomic homeostasis result from baroreceptor stimulation, which occurs particularly at the time of balloon inflation in the region of the carotid sinus. The response can be profound enough to induce asystole or even complete cessation of postganglionic sympathetic nerve activity. Frequency and factors predisposing a patient to CAS-D have been investigated in several studies; however, there are significant discrepancies in results among reports. Lack of consistent findings may arise from using different methods and definitions, as well as other factors discussed in detail in this review. Furthermore, a correlation of CAS-D with short and long-term outcomes has been investigated only in small and mostly retrospective studies, explaining why its prognostic significance remains uncertain. In this manuscript, we have focused on risk factors, pathophysiology and management of periprocedural autonomic dysfunction. As there is no standardized approach to the treatment of CAS-D, we present an algorithm for the periprocedural management of patients undergoing CAS. The proposed algorithm was developed based on our procedural experience as well as data from the available literature. The Yale Algorithm was successfully implemented at our institution and we are currently collecting data for short- and long-term safety. © 2014 Wiley Periodicals, Inc. © 2014 Wiley Periodicals, Inc.

The treatment of coronary small vessel disease (SVD) remains an unresolved issue. Drug-eluting stents (DES) have limited efficacy due to increased rates of instent-restenosis, mainly caused by late lumen loss. Drug-coated balloons (DCB) are a promising technique because native vessels remain structurally unchanged. Basel Stent Kosten-Effektivitäts Trial: Drug-Coated Balloons vs. Drug-Eluting Stents in Small Vessel Interventions (BASKET-SMALL 2) is a multicenter, randomized, controlled, noninferiority trial of DCB vs DES in native SVD for clinical endpoints. Seven hundred fifty-eight patients with de novo lesions in vessels <3 mm in diameter and an indication for percutaneous coronary intervention such as stable angina pectoris, silent ischemia, or acute coronary syndromes are randomized 1:1 to angioplasty with DCB vs implantation of a DES after successful initial balloon angioplasty. The primary endpoint is the combination of cardiac death, nonfatal myocardial infarction, and target-vessel revascularization up to 1 year. Secondary endpoints include stent thrombosis, Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding, and long-term outcome up to 3 years. Based on clinical endpoints after 1 year, we plan to assess the noninferiority of DCB compared to DES in patients undergoing primary percutaneous coronary intervention for SVD. Results will be available in the second half of 2018. This study will compare DCB and DES regarding long-term safety and efficacy for the treatment of SVD in a large all-comer population. © 2018 The Authors.

Emotional enhancement of memory by noradrenergic mechanisms is well-described, but the long-term consequences of such enhancement are poorly understood. Over time, memory traces are thought to undergo a neural reorganization, that is, a systems consolidation, during which they are, at least partly, transferred from the hippocampus to neocortical networks. This transfer is accompanied by a decrease in episodic detailedness. Here we investigated whether norepinephrine (NE) administration into the basolateral amygdala after training on an inhibitory avoidance discrimination task, comprising two distinct training contexts, alters systems consolidation dynamics to maintain episodic-like accuracy and hippocampus dependency of remote memory. At a 2-d retention test, both saline- and NE-treated rats accurately discriminated the training context in which they had received footshock. Hippocampal inactivation with muscimol before retention testing disrupted discrimination of the shock context in both treatment groups. At 28 d, saline-treated rats showed hippocampus-independent retrieval and lack of discrimination. In contrast, NE-treated rats continued to display accurate memory of the shock-context association. Hippocampal inactivation at this remote retention test blocked episodic-like accuracy and induced a general memory impairment. These findings suggest that the NE treatment altered systems consolidation dynamics by maintaining hippocampal involvement in the memory. This shift in systems consolidation was paralleled by time-regulated DNA methylation and transcriptional changes of memory-related genes, namely Reln and Pkm ζ, in the hippocampus and neocortex. The findings provide evidence suggesting that consolidation of emotional memories by noradrenergic mechanisms alters systems consolidation dynamics and, as a consequence, influences the maintenance of long-term episodic-like accuracy of memory.

Delayed breast reconstruction is an option for women who have undergone mastectomy; however, uptake is low. The purpose of this study was to identify premastectomy and postmastectomy demographic, clinical, and psychosocial predictors of uptake of delayed breast reconstruction in the long-term survivorship period. This was a prospective longitudinal survey study of mastectomy patients in which a repeated measures design was used to evaluate uptake of delayed breast reconstruction. Demographic, clinical, and psychosocial variables were collected before mastectomy and 1 year after mastectomy. Information regarding uptake of delayed breast reconstruction was collected at approximately 6 years after mastectomy. A predictive model was designed using a multivariate logistic regression model and Akiake information criterion stepwise algorithm. Ninety-six mastectomy patients were followed from before mastectomy to 75.2 months after mastectomy, and 35 women (36.5 percent) underwent delayed breast reconstruction. Women who elected for delayed breast reconstruction experienced worsening of body concerns from before mastectomy to 1 year after mastectomy, compared with women who did not elect to undergo delayed breast reconstruction (p = 0.03). Mean scores for psychological distress were significantly worse both before mastectomy and 1 year after mastectomy in women who went on to undergo delayed breast reconstruction compared with those who did not undergo delayed breast reconstruction (p = 0.034 and p = 0.022, respectively). A predictive model for the uptake of delayed breast reconstruction was developed using demographic, clinical, and psychosocial characteristics. The area under the receiver operating characteristic curve was 85 percent, indicating good precision. Women who are experiencing higher levels of distress, anxiety, and body concerns both before and after mastectomy appear to be significantly likely to select delayed breast reconstruction. This may have implications for postreconstruction satisfaction and psychosocial functioning. Risk, III.

Prophylactic aortic root replacement improves survival in patients with Marfan syndrome with aortic root aneurysms, but the optimal procedure remains undefined. Adult patients with Marfan syndrome who had Bentall or aortic valve-sparing root replacement (VSRR) procedures between 1997 and 2013 were identified. Comprehensive follow-up information was obtained from hospital charts and telephone contact. One hundred sixty-five adult patients with Marfan syndrome (aged > 20 years) had either VSRR (n = 98; 69 reimplantation, 29 remodeling) or Bentall (n = 67) procedures. Patients undergoing Bentall procedure were older (median, 37 vs 36 years; P = .03), had larger median preoperative sinus diameter (5.5 cm vs 5.0 cm; P = .003), more aortic dissections (25.4% vs 4.1%; P < .001), higher incidence of moderate or severe aortic insufficiency (49.3% vs 14.4%; P < .001) and more urgent or emergent operations (24.6% vs 3.3%; P < .001). There were no hospital deaths and 9 late deaths in more than 17 years of follow-up (median, 7.8 deaths). Ten-year survival was 90.5% in patients undergoing Bentall procedure and 96.3% in patients undergoing VSRR (P = .10). Multivariable analysis revealed that VSRR was associated with fewer thromboembolic or hemorrhagic events (hazard ratio, 0.16; 95% confidence interval, 0.03-0.85; P = .03). There was no independent difference in long-term survival, freedom from reoperation, or freedom from endocarditis between the 2 procedures. After prophylactic root replacement in patients with Marfan syndrome, patients undergoing Bentall and valve-sparing procedures have similar late survival, freedom from root reoperation, and freedom from endocarditis. However, valve-sparing procedures result in significantly fewer thromboembolic and hemorrhagic events. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc.

Patients undergoing acute left main (LM) coronary artery revascularization have a high mortality and natriuretic peptides such as N-terminal pro-B-type (NT-proBNP) have been shown to have prognostic value in patients with acute coronary syndromes. The present study looked at the prognostic value of NT-proBNP in these patients. We studied all consecutive patients undergoing acute LM coronary artery percutaneous coronary intervention between January 2005 and December 2008 in whom NT-proBNP was measured (n=71). We analyzed the clinical characteristics and the short- and long-term outcomes in relation to NT-proBNP level at admission. Median NT-proBNP was 1,364 ng/L, ranging from 46 to 70,000 ng/L. NT-proBNP was elevated in 63 (89%) patients and was ≥1,000ng/L in 42 (59%). Log NT-proBNP (hazard ratio [HR] 3.51, 95% confidence interval [CI] 1.55-7.97, P=0.003) and left ventricular ejection fraction (HR 0.95, 95%CI 0.91-0.99, P=0.007) were predictors for all-cause mortality. Log NT-proBNP was the only independent significant predictor of cardiovascular mortality. In-hospital mortality was 0% for patients with NT-proBNP <1,000, but 17% for those with NT-proBNP ≥1,000 (P=0.036). NT-proBNP is a strong predictor of outcome in patients undergoing acute LM coronary artery stenting. Mortality in such patients is high, but those with NT-proBNP < 1,000ng/L may have a favorable short- and long-term prognosis. Further research, including a larger patient population, is needed to determine the optimal cut-off value for NT-proBNP in patients undergoing acute LM coronary artery intervention.
