Gastric band is safe and effective at three years in a national study subgroup of non-morbidly obese patients

Aim To analyze the 3-year outcomes of lower body mass index (BMI) (<35 kg/m2) adjustable gastric band (AGB) recipients across multiple sites in the French health insurance system. Methods From prospectively collected data on a cohort of 517 morbidly obese Swedish Adjustable Gastric Band® (SAGB) patients (Clinical Trials Web database, #NCT01183975), a retrospective analysis of a subgroup of 29 low-BMI patients was conducted. Patients had a severe obesity-related comorbidity, had undergone a prior bariatric procedure requiring reintervention, or had a maximum adult BMI≥40. Safety (mortality, adverse events) and effectiveness (BMI change, excess weight loss [EWL, %], total body weight loss [%TBWL], quality of life [QoL], and comorbidities) were evaluated. Results Multiple surgical teams/sites enrolled patients and performed SAGB procedures between September 2, 2007 and April 30, 2008. Of 29 low-BMI patients (mean age, 41.3 ± 10.3 years), 89.7% were female, and obesity duration was 13.6 ± 7.3 years. Mean BMI was 31.5 ± 3.7; there were 37 comorbidities in 15/29 patients. At 3-year follow-up, BMI was 29.4 ± 4.9 (mean change, -2.3 ± 6.2; P = 0.069); total cohort EWL, 7.3 ± 74.8%; TBWL, 6.2 ± 18.8%; BMI≥30 to <35 EWL, 38.8 ± 48.0%; there were 7 comorbidities in 15/29 patients (P < 0.031). There were 20 adverse events in 13 patients (44.8%); SAGBs were retained in 25/29 (86.2%) at 3 years. Conclusions In a retrospective analysis of a subgroup of BMI<35 kg/m2 patients, some following a prior bariatric procedure, SAGB was found to be safe and effective at 3-year follow-up

Treatment of Persistent Large Gastrocutaneous Fistulas After Bariatric Surgery. Preliminary Experience with Endoscopic Kehr's T-Tube Placement

Purpose Post-bariatric surgery gastrocutaneous fistula is a chronic leak with an incidence of 1.7 to 4.0% and no standardized management. A large gastrocutaneous fistula (LGCF) is not indicated for treatment with pigtail drains. We aimed to evaluate results of a novel treatment using endoscopic Kehr's T-tube placement.Methods Only patients with a postoperative LGCF duration of &gt;10 days and a flow rate of &gt; 50 cc by external drainage after revisional surgery for sepsis were included. Endoscopic placement of Kehr's T-tube was performed. Patients had been reoperated with wash and drainage for severe sepsis after initial bariatric surgery in which no fistula had been discovered. Patients not reoperated, or with a fistula requiring intraoperative Kehr's T-tube placement, or a pigtail drain were excluded. Primary outcomes were endoscopic characteristics and results (LGCF closure rate, Kehr T-tube retention time, etc.).Results The study group included 12 women, 2 men; body mass index 43.1 +/- 4.5 kg/m(2). Interventions were SG (7), RYGB (2), OAGB (4), and SADI-S (1). Endoscopic assessment was carried out after a mean of 33.2 +/- 44.3 days after the bariatric procedure. The mean fistula orifice diameter was 2.0 +/- 0.9 cm. Kehr's T-tube was positioned at a mean 51.5 +/- 54.8 days after the bariatric procedure. T-tube tolerance was excellent. Mean additional days: hospitalization, 34.4 +/- 27.0; T-tube retention, 86.4 +/- 73.1; fistula healing, 139.9 +/- 111.5,LGCF closure rate, 92.9%. Complications: 1 pulmonary embolism, 2 T-tube migrations,1 drain-path bleed, 1 skin abscess. No mortality.Conclusions Endoscopic Kehr's T-tube placement was successful in closing persistent post-bariatric surgery LGCF in 92.9% of patients

Recent advances in the structural molecular biology of Ets transcription factors: interactions, interfaces and inhibition

The Ets family of eukaryotic transcription factors is based around the conserved Ets DNA-binding domain. Although their DNA-binding selectivity is biochemically and structurally well characterized, structures of homodimeric and ternary complexes point to Ets domains functioning as versatile protein-interaction modules. In the present paper, we review the progress made over the last decade to elucidate the structural mechanisms involved in modulation of DNA binding and protein partner selection during dimerization. We see that Ets domains, although conserved around a core architecture, have evolved to utilize a variety of interaction surfaces and binding mechanisms, reflecting Ets domains as dynamic interfaces for both DNA and protein interaction. Furthermore, we discuss recent advances in drug development for inhibition of Ets factors, and the roles structural biology can play in their future

The impact of a bariatric rehabilitation service on weight loss and psychological adjustment - study protocol

Bariatric surgery is currently the most effective form of obesity management for those whose BMI is greater than 40 (or 35 with co morbidities). A minority of patients, however, either do not show the desired loss of excess weight or show weight regain by follow up. Research highlights some of the reasons for this variability, most of which centres on the absence of any psychological support with patients describing how although surgery fixes their body, psychological issues relating to dietary control, self esteem, coping and emotional eating remain neglected.The present study aims to evaluate the impact of a health psychology led bariatric rehabilitation service (BRS) on patient health outcomes. The bariatric rehabilitation service will provide information, support and mentoring pre and post surgery and will address psychological issues such as dietary control, self esteem, coping and emotional eating. The package reflects the rehabilitation services now common place for patients post heart attack and stroke which have been shown to improve patient health outcomes

The effectiveness of bariatric surgery on long term psychosocial quality of life – A systematic review

© 2015 Asia Oceania Association for the Study of Obesity Background Little is known about the psychological effects of bariatric surgery. This review aimed to assess long term effectiveness of bariatric surgery on psychosocial quality of life (QoL) of obese adults compared to non-surgical interventions. Methods A systematic review of the literature was conducted, six electronic databases, plus other relevant sources were searched from inception to January 2014. The main outcome sought was a QoL measure with a minimum 12 months follow-up. Three reviewers screened records, extracted data and independently read through full articles for eligibility and quality using standardised forms. Findings were analysed using narrative synthesis. Results Of 4383 identified references included in the review, 11 studies showed bariatric surgery to be effective long term for overall QoL than non-surgical treatments with specifically modest benefits psychosocially. Significant improvements in psychosocial QoL alongside improved physical QoL were observed after 2 year follow-up post-surgery compared to non-surgical interventions. However improvements in psychosocial QoL after surgery at 10 year follow up were minimal when compared to non-surgical interventions. When compared to untreated control groups, long term psychosocial QoL did not improve after bariatric surgery despite major improvements in physical QoL, significant weight loss and co-morbidities. Conclusions Results on long term psychosocial QoL remain uncertain with some suggestion of psychological disorder persisting. This highlights need for psychological intervention post-surgery and further research to provide more data on long-term psychosocial QoL following bariatric surgery

Isoniazid preventive therapy-related adverse events among Malawian adults on antiretroviral therapy: A cohort study.

Adverse events may be a cause of observed poor completion of isoniazid preventive therapy (IPT) among people living with HIV in high tuberculosis burden areas. Data on IPT-related adverse events (AE) from sub-Saharan Africa are scarce. We report IPT-related AEs, associated clinical characteristics, and IPT discontinuations in adults who were stable on antiretroviral therapy (ART) when they initiated IPT. Cohort study nested within a randomized, controlled, clinical trial of cotrimoxazole and chloroquine prophylaxis in Malawians aged ≥ 18 years and virologically suppressed on ART. Eight hundred sixty-nine patients were followed for a median of 6 months after IPT initiation. IPT relatedness of AEs was determined retrospectively with the World Health Organization case-causality tool. Frailty survival regression modeling identified factors associated with time to first probably IPT-related AE. The overall IPT-related AE incidence rate was 1.1/person year of observation. IPT relatedness was mostly uncertain and few AEs were severe. Most common were liver and hematological toxicities. Higher age increased risk of a probably IPT-related AE (aHR = 1.02; 95% CI 1.00-1.06; P = .06) and higher weight reduced this risk (aHR = 0.98; 95% CI 0.96-1.00; P = .03). Of 869 patients, 114 (13%) discontinued IPT and 94/114 (82%) discontinuations occurred at the time of a possibly or probably IPT-related AE. We observed a high incidence of mostly mild IPT-related AEs among individuals who were stable on ART. More than 1 in 8 persons discontinued IPT. These findings inform strategies to improve implementation of IPT in adults on ART, including close monitoring of groups at higher risk of IPT-related AEs

The impact of psychological support on weight loss post weight loss surgery: a randomised control trial

Background The purpose of the present study is to evaluate the impact of a health psychology-led bariatric rehabilitation service (BRS) on patient weight loss following bariatric surgery at 1 year. Methods A single-site open-randomised parallel group control trial based at St. Richard’s Hospital in Chichester in the UK. Patients (n=162) were recruited immediately prior to Roux-en-Y gastric bypass and randomly allocated to receive either treatment as usual (n=80) or the BRS (n=82). The BRS involved three 50-min one-to-one sessions with a health psychologist and provided information, support and mentoring pre and post surgery addressing psychological issues such as dietary control, self esteem, coping and emotional eating. Weight loss was assessed at 1 year. The key outcome variable was BMI and change in BMI. Results Follow-up weight was available for 145 patients. Intention-to-treat analysis (n=162) using last measured weights showed that mean change in BMI by 1 year post surgery was −16.49. There was no significant difference between the two groups (control group=−16.37, 95 % CI= 15.15–17.57; intervention=−16.6, 95 % CI=15.42–17.81; ηp 2=0.001). Similarly, explanatory analysis (n=145) showed a mean change inBMI of −17.17. The difference between the two groups was not significant (control group=−16.9, 95 % CI=15.78–18.18; intervention=−17.35, 95 % CI=18.5– 16.16; ηp 2=0.001). Conclusions Psychological support pre and post bariatric surgery had no impact on weight loss as measured by BMI and change in BMI by 1 year. It is argued that psychological support should be targeted to patients who start to demonstrate weight regain at a later stage

Etiology, Presentation, and Risk Factors for Diarrheal Syndromes in 3 Sub-Saharan African Countries After the Introduction of Rotavirus Vaccines From the Vaccine Impact on Diarrhea in Africa (VIDA) Study.

BACKGROUND: Diarrheal disease is heterogeneous, including watery diarrhea (WD) and dysentery, some cases of which become persistent diarrhea (PD). Changes in risk over time necessitate updated knowledge of these syndromes in sub-Saharan Africa. METHODS: The Vaccine Impact on Diarrhea in Africa (VIDA) study was an age-stratified, case-control study of moderate-to-severe diarrhea among children <5 years old in The Gambia, Mali, and Kenya (2015-2018). We analyzed cases with follow-up of about 60 days after enrollment to detect PD (lasting ≥14 days), examined the features of WD and dysentery, and examined determinants for progression to and sequelae from PD. Data were compared with those from the Global Enteric Multicenter Study (GEMS) to detect temporal changes. Etiology was assessed from stool samples using pathogen attributable fractions (AFs), and predictors were assessed using χ2 tests or multivariate regression, where appropriate. RESULTS: Among 4606 children with moderate-to-severe diarrhea, 3895 (84.6%) had WD and 711 (15.4%) had dysentery. PD was more frequent among infants (11.3%) than in children 12-23 months (9.9%) or 24-59 months (7.3%), P = .001 and higher in Kenya (15.5%) than in The Gambia (9.3%) or Mali (4.3%), P < .001; the frequencies were similar among children with WD (9.7%) and those with dysentery (9.4%). Compared to children not treated with antibiotics, those who received antibiotics had a lower frequency of PD overall (7.4% vs 10.1%, P = .01), and particularly among those with WD (6.3% vs 10.0%; P = .01) but not among children with dysentery (8.5% vs 11.0%; P = .27). For those with watery PD, Cryptosporidium and norovirus had the highest AFs among infants (0.16 and 0.12, respectively), while Shigella had the highest AF (0.25) in older children. The odds of PD decreased significantly over time in Mali and Kenya while increasing significantly in The Gambia. CONCLUSIONS: The burden of PD endures in sub-Saharan Africa, with nearly 10% of episodes of WD and dysentery becoming persistent

European Position Paper on Rhinosinusitis and Nasal Polyps 2020

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise. The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.Peer reviewe
