RESUMO

INTRODUCTION: Over half of Americans and up to 78% of US Veteran population meet criteria for obesity. Perioperatively placed intragastric balloon (IGB) can accelerate weight loss goals for safe surgical candidacy, however weight regain is common after removal. Glucagon-like peptide-1-receptor agonists (GLP1RA) may provide a more sustainable weight loss solution after surgery. We hypothesize that weight regain will be less at 1 year after initiation of GLP1RA than IGB placement in Veterans. METHODS: Retrospective review of prospective databases of perioperatively placed intragastric balloon cohort from 1/2019-1/2023 compared to patients who received initiatory GLP1RA from 6/2021-8/2022 at a VA Medical Center(VAMC). All patients were enrolled in the VAMC MOVE! multidisciplinary weight management program for a minimum of 12 weeks. Outcomes measured were patients' weights at 0, 3, 6, and 12 months and weight change for these intervals. Exclusion criteria included history of bariatric surgery and incomplete weight loss data. RESULTS: Two-hundred-twenty-three patients met inclusion criteria; 110 (49%) patients excluded. Mean age was 54 ± 11 years, the majority (78, 69%) were male, and the mean initial BMI was 37 ± 5.9 kg/m2. Seventeen (15%) patients underwent IGB placement and 96 (85%) patients received semaglutide. Weight (kg) change was measured at intervals: 0-3 months:- 11.8(- 17,- 9.5) IGB vs. - 5.1(- 7.4,- 2.3) semaglutide, p < 0.0001; 0-6 months:- 12.7(- 18.4,- 9.9) vs. - 9.4(- 12.6,- 6.1), p = 0.03; 3-6 months:- 0.5(- 2.3,2.3) vs. - 4.3(- 6.8,- 1.6), p < 0.0001; 6-12 months:3(0,7.3) vs. - 1.9(- 4.7,1), p = 0.0006. CONCLUSION: Weight loss occurs more rapidly in the first 6 months after intragastric balloon placement compared to semaglutide (- 12.7 vs. - 9.4 kg, p = 0.03). Despite ongoing attendance in a comprehensive weight loss program, weight regain is common after IGB removal by an average of 3 kg (23.6%) at 1 year. In contrast, patients on GLP1RA (semaglutide) continue to lose weight during this period. Further studies are needed to determine if optimal long-term outcomes may result from combination therapy with intragastric balloon and semaglutide.

RESUMO

CONTEXT: Obesity is a chronic disease that is difficult to manage without holistic therapy. The therapeutic armamentarium for obesity primarily consists of 4 forms of therapy: lifestyle modification (ie, diet and exercise), cognitive behavioral therapy, pharmacotherapy, and bariatric surgery. EVIDENCE ACQUISITION: Evidence was consolidated from randomized controlled trials, observational studies, and meta-analyses. EVIDENCE SYNTHESIS: After 2 years, lifestyle interventions can facilitate weight loss that equates to ~5%. Even though lifestyle interventions are plagued by weight regain, they can have substantial effects on type 2 diabetes and cardiovascular disease risk. Although 10-year percentage excess weight loss can surpass 50% after bariatric surgery, weight regain is likely. To mitigate weight regain, instituting a multifactorial maintenance program is imperative. Such a program can integrate diet, exercise, and pharmacotherapy. Moreover, behavioral therapy can complement a maintenance program well. CONCLUSIONS: Obesity is best managed by a multidisciplinary clinical team that integrates diet, exercise, and pharmacotherapy. Bariatric surgery is needed to manage type 2 diabetes and obesity in select patients.

RESUMO

In situ transgenesis methods such as viruses and electroporation can rapidly create somatic transgenic mice but lack control over copy number, zygosity, and locus specificity. Here we establish mosaic analysis by dual recombinase-mediated cassette exchange (MADR), which permits stable labeling of mutant cells expressing transgenic elements from precisely defined chromosomal loci. We provide a toolkit of MADR elements for combination labeling, inducible and reversible transgene manipulation, VCre recombinase expression, and transgenesis of human cells. Further, we demonstrate the versatility of MADR by creating glioma models with mixed reporter-identified zygosity or with "personalized" driver mutations from pediatric glioma. MADR is extensible to thousands of existing mouse lines, providing a flexible platform to democratize the generation of somatic mosaic mice. VIDEO ABSTRACT.

RESUMO

BACKGROUND: Obesity is a major challenge for people with schizophrenia.AimsWe assessed whether STEPWISE, a theory-based, group structured lifestyle education programme could support weight reduction in people with schizophrenia. METHOD: In this randomised controlled trial (study registration: ISRCTN19447796), we recruited adults with schizophrenia, schizoaffective disorder or first-episode psychosis from ten mental health organisations in England. Participants were randomly allocated to the STEPWISE intervention or treatment as usual. The 12-month intervention comprised four 2.5 h weekly group sessions, followed by 2-weekly maintenance contact and group sessions at 4, 7 and 10 months. The primary outcome was weight change after 12 months. Key secondary outcomes included diet, physical activity, biomedical measures and patient-related outcome measures. Cost-effectiveness was assessed and a mixed-methods process evaluation was included. RESULTS: Between 10 March 2015 and 31 March 2016, we recruited 414 people (intervention 208, usual care 206) with 341 (84.4%) participants completing the trial. At 12 months, weight reduction did not differ between groups (mean difference 0.0 kg, 95% CI -1.6 to 1.7, P = 0.963); physical activity, dietary intake and biochemical measures were unchanged. STEPWISE was well-received by participants and facilitators. The healthcare perspective incremental cost-effectiveness ratio was £246 921 per quality-adjusted life-year gained. CONCLUSIONS: Participants were successfully recruited and retained, indicating a strong interest in weight interventions; however, the STEPWISE intervention was neither clinically nor cost-effective. Further research is needed to determine how to manage overweight and obesity in people with schizophrenia.Declaration of interestR.I.G.H. received fees for lecturing, consultancy work and attendance at conferences from the following: Boehringer Ingelheim, Eli Lilly, Janssen, Lundbeck, Novo Nordisk, Novartis, Otsuka, Sanofi, Sunovion, Takeda, MSD.

RESUMO

BACKGROUND: Obesity is twice as common in people with schizophrenia as in the general population. The National Institute for Health and Care Excellence guidance recommends that people with psychosis or schizophrenia, especially those taking antipsychotics, be offered a healthy eating and physical activity programme by their mental health care provider. There is insufficient evidence to inform how these lifestyle services should be commissioned. OBJECTIVES: To develop a lifestyle intervention for people with first episode psychosis or schizophrenia and to evaluate its clinical effectiveness, cost-effectiveness, delivery and acceptability. DESIGN: A two-arm, analyst-blind, parallel-group, randomised controlled trial, with a 1 : 1 allocation ratio, using web-based randomisation; a mixed-methods process evaluation, including qualitative case study methods and logic modelling; and a cost-utility analysis. SETTING: Ten community mental health trusts in England. PARTICIPANTS: People with first episode psychosis, schizophrenia or schizoaffective disorder. INTERVENTIONS: Intervention group: (1) four 2.5-hour group-based structured lifestyle self-management education sessions, 1 week apart; (2) multimodal fortnightly support contacts; (3) three 2.5-hour group booster sessions at 3-monthly intervals, post core sessions. Control group: usual care assessed through a longitudinal survey. All participants received standard written lifestyle information. MAIN OUTCOME MEASURES: The primary outcome was change in weight (kg) at 12 months post randomisation. The key secondary outcomes measured at 3 and 12 months included self-reported nutrition (measured with the Dietary Instrument for Nutrition Education questionnaire), objectively measured physical activity measured by accelerometry [GENEActiv (Activinsights, Kimbolton, UK)], biomedical measures, adverse events, patient-reported outcome measures and a health economic assessment. RESULTS: The trial recruited 414 participants (intervention arm: 208 participants; usual care: 206 participants) between 10 March 2015 and 31 March 2016. A total of 341 participants (81.6%) completed the trial. A total of 412 participants were analysed. After 12 months, weight change did not differ between the groups (mean difference 0.0 kg, 95% confidence interval -1.59 to 1.67 kg; p = 0.964); physical activity, dietary intake and biochemical measures were unchanged. Glycated haemoglobin, fasting glucose and lipid profile were unchanged by the intervention. Quality of life, psychiatric symptoms and illness perception did not change during the trial. There were three deaths, but none was related to the intervention. Most adverse events were expected and related to the psychiatric illness. The process evaluation showed that the intervention was acceptable, with participants valuing the opportunity to interact with others facing similar challenges. Session feedback indicated that 87.2% of participants agreed that the sessions had met their needs. Some indicated the desire for more ongoing support. Professionals felt that the intervention was under-resourced and questioned the long-term sustainability within current NHS settings. Professionals would have preferred greater access to participants' behaviour data to tailor the intervention better. The incremental cost-effectiveness ratio from the health-care perspective is £246,921 per quality-adjusted life-year (QALY) gained and the incremental cost-effectiveness ratio from the societal perspective is £367,543 per QALY gained. CONCLUSIONS: Despite the challenges of undertaking clinical research in this population, the trial successfully recruited and retained participants, indicating a high level of interest in weight management interventions; however, the STEPWISE intervention was neither clinically effective nor cost-effective. Further research will be required to define how overweight and obesity in people with schizophrenia should be managed. The trial results suggest that lifestyle programmes for people with schizophrenia may need greater resourcing than for other populations, and interventions that have been shown to be effective in other populations, such as people with diabetes mellitus, are not necessarily effective in people with schizophrenia.

RESUMO

Trophic factor delivery to the brain using stem cell-derived neural progenitors is a powerful way to bypass the blood-brain barrier. Protection of diseased neurons using this technology is a promising therapy for neurodegenerative diseases. Glial cell line-derived neurotrophic factor (GDNF) has provided benefits to Parkinsonian patients and is being used in a clinical trial for amyotrophic lateral sclerosis. However, chronic trophic factor delivery prohibits dose adjustment or cessation if side effects develop. To address this, we engineered a doxycycline-regulated vector, allowing inducible and reversible expression of a therapeutic molecule. Human induced pluripotent stem cell (iPSC)-derived neural progenitors were stably transfected with the vector and transplanted into the adult mouse brain. Doxycycline can penetrate the graft, with addition and withdrawal providing inducible and reversible GDNF expression in vivo, over multiple cycles. Our findings provide proof of concept for combining gene and stem cell therapy for effective modulation of ectopic protein expression in transplanted cells.

RESUMO

Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis and inflammation involving the axial skeleton and/or peripheral joints. It is more likely to be associated with metabolic syndrome and diabetes when compared with other inflammatory arthritides. Tumor necrosis factor-α (TNF-α) is one of several cytokines often elevated in rheumatologic disorders including PsA and has also been found to be elevated in patients with obesity, metabolic syndrome, diabetes, and/or atherosclerotic disease. We describe the case of a patient with PsA as well as poorly controlled type 2 diabetes mellitus who experienced not only improvement in his psoriasis and arthritis with the anti-TNF-α agent etanercept but also recurrent hypoglycemia and significant improvement in hemoglobin A1c despite discontinuation of all conventional therapy for diabetes.

RESUMO

BACKGROUND: In adults, membranous nephropathy (MN) is a major cause of nephrotic syndrome. While a majority of cases of MN are idiopathic, secondary forms can be seen in the setting of autoimmune disease, neoplasia, infection, and after being exposed to certain therapeutic agents. Both human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections could cause MN. However, the effect of coexisting HIV and HCV infection on the spectrum and progression of kidney disease as well as the effect of MN treatment on HIV and HCV infection are not well known. METHODS: In this study, we describe a patient with hemophilia A and acquired HIV and HCV infections, a patient who developed severe nephrotic syndrome and for whom renal biopsy showed MN. RESULTS: Patient responded well to adrenocorticotropic hormone gel without adversely affecting HIV or HCV infections. CONCLUSION: Adrenocorticotropic hormone gel might be useful in the management of complex cases of idiopathic MN.

RESUMO

OBJECTIVE: To investigate the barriers and facilitators of an effective implementation of an outcome monitoring and feedback system in a UK National Health Service psychological therapy service. METHOD: An outcome monitoring system was introduced in two services. Enhanced feedback was given to therapists after session 4. Qualitative and quantitative methods were used, including questionnaires for therapists and patients. Thematic analysis was carried out on written and verbal feedback from therapists. Analysis of patient outcomes for 202 episodes of therapy was compared with benchmark data of 136 episodes of therapy for which feedback was not given to therapists. RESULTS: Themes influencing the feasibility and acceptability of the feedback system were the extent to which therapists integrated the measures and feedback into the therapy, availability of administrative support, information technology, and complexity of the service. There were low levels of therapist actions resulting from the feedback, including discussing the feedback in supervision and with patients. CONCLUSIONS: The findings support the feasibility and acceptability of setting up a routine system in a complex service, but a number of challenges and barriers have to be overcome and therapist differences are apparent. More research on implementation and effectiveness is needed in diverse clinical settings.

RESUMO

The National Cholesterol Education Program's Adult Treatment Panel III definition of the metabolic syndrome identifies those at high risk for diabetes mellitus and/or a cardiac event by clustering a number of easily measured clinical findings, including abdominal obesity, elevated plasma levels of triglycerides, low plasma levels of high-density lipoprotein cholesterol, elevated fasting blood glucose, and elevated blood pressure. The presence of > or = 3 of these 5 risk factors justifies a diagnosis of the metabolic syndrome. This article focuses on root causes of the syndrome (atherogenic diet, sedentary lifestyle, and overweight/obesity) and highlights recent studies that demonstrate the effectiveness of therapeutic lifestyle changes in improving or preventing the components of the metabolic syndrome. We offer a practical approach with a focus that embraces not only patients, but also physicians and healthcare professionals as well as the larger healthcare system.
