OBJECTIVES: A number of research studies support the weight loss effects of metformin and topiramate for obese people with schizophrenia. However, only a few studies have addressed the sustainability of the body weight reduction after discontinuation of these drugs. Moreover, head-to-head studies are still lacking. The study aims to evaluate and compare the efficacy of metformin and topiramate in weight reduction and weight maintenance after discontinuation of these drugs in obese people with schizophrenia...

BACKGROUND: Effective approaches that engage men in weight loss and lifestyle change are important because of worldwide increases, including in Canada, in obesity and chronic diseases. Football Fans in Training (FFIT), developed in Scotland, successfully tackled these problems by engaging overweight/obese male football fans in sustained weight loss and positive health behaviours, through program deliveries at professional football stadia. METHODS: Aims: 1) Adapt FFIT to hockey within the Canadian context and integrate with HealtheSteps™ (evidence-based lifestyle program) to develop Hockey Fans in Training (Hockey FIT); 2) Explore potential for Hockey FIT to help overweight/obese men lose weight and improve other outcomes by 12 weeks, and retain these improvements to 12 months; 3) Evaluate feasibility of recruiting and retaining overweight/obese men; 4) Evaluate acceptability of Hockey FIT; and 5) Conduct program optimization via a process evaluation...

Obesity is a common disorder with complex causes. The epidemic has spurred significant advances in the understanding of nutritional approaches to treating obesity. Although the primary challenge is to introduce a dietary intake that creates an energy deficit, clinicians should also consider targeted risk factor modification with manipulation of the nutrient profile of the weight-reducing diet. These strategies produce significant weight loss and improvements in cardiometabolic risk factors. Future research is needed to better understand how to personalize nutrient prescriptions further to promote optimal risk modification and maintenance of long-term energy balance in the weight-reduced state...

Creating a negative energy balance by decreasing caloric consumption and increasing physical activity is a common strategy used to treat obesity. A large number of review and original research papers have considered the role of physical activity in weight loss and maintenance. However, their conclusions are at times conflicting. In this review, we have critically evaluated the findings of systematic reviews and meta-analyses and supplemented their conclusions with recently published, high-quality clinical trials...

Metabolic adaptation to weight changes relates to body weight control, obesity and malnutrition. Adaptive thermogenesis (AT) refers to changes in resting and non-resting energy expenditure (REE and nREE) which are independent from changes in fat-free mass (FFM) and FFM composition. AT differs in response to changes in energy balance. With negative energy balance, AT is directed towards energy sparing. It relates to a reset of biological defence of body weight and mainly refers to REE. After weight loss, AT of nREE adds to weight maintenance...

Long-acting injectable antipsychotics (LAIs) are among the most effective treatments in psychiatry, yet they remain underutilized in clinical practice. Although LAIs are typically used to maintain treatment adherence in patients with chronic schizophrenia, recent research has suggested that they may also provide an effective treatment strategy for patients with early-phase or first-episode disease. In October 2015, a group of 8 experts on the management of schizophrenia and LAIs met to evaluate the evidence surrounding the efficacy, safety, and cost-effectiveness of LAIs and to develop practical recommendations regarding the clinical use, education, and unmet needs related to LAIs...

BACKGROUND: Power analysis is a critical aspect of the design of experiments to detect an effect of a given size. When multiple hypotheses are tested simultaneously, multiplicity adjustments to p-values should be taken into account in power analysis. There are a limited number of studies on power analysis in multiple testing procedures. For some methods, the theoretical analysis is difficult and extensive numerical simulations are often needed, while other methods oversimplify the information under the alternative hypothesis...

OBJECTIVE: Intensive lifestyle interventions (ILI) are criticised for ineffective obesity treatment because weight loss over time is modest and thus of limited clinical relevance. However, a subgroup (5-30%) maintains a clinical weight loss >10%, but it is not clear if cardiometabolic health follows this pattern. The aim was to study the effect of different magnitudes of weight loss maintenance after ILI on cardiometabolic health. METHODS: Eighty out of 2420 former participants (age: 36±1, BMI: 38±1, (means ±SE)) in an 11-12-week ILI were recruited into 3 groups; clinical weight loss maintenance (>10% weight loss), moderate maintenance (1-10%), and weight regain based on weight loss at follow-up (5...

BACKGROUND: Whether testosterone treatment has benefits on body composition over and above caloric restriction in men is unknown. We hypothesised that testosterone treatment augments diet-induced loss of fat mass and prevents loss of muscle mass. METHODS: We conducted a randomised double-blind, parallel, placebo controlled trial at a tertiary referral centre. A total of 100 obese men (body mass index ≥ 30 kg/m(2)) with a total testosterone level of or below 12 nmol/L and a median age of 53 years (interquartile range 47-60) receiving 10 weeks of a very low energy diet (VLED) followed by 46 weeks of weight maintenance were randomly assigned at baseline to 56 weeks of 10-weekly intramuscular testosterone undecanoate (n = 49, cases) or matching placebo (n = 51, controls)...

Skeletal muscle dysfunction and atrophy are characteristic features accompanying chronic conditions. Epigenetic events regulate muscle mass and function maintenance. We hypothesized that the pattern of epigenetic events (muscle-enriched microRNAs and histone acetylation) and acetylation of transcription factors known to signal muscle wasting may differ between early- and late-time points in skeletal muscles of mice exposed to hindlimb immobilization (I) and recovery following I. Body and muscle weights, grip strength, muscle-enriched microRNAs, histone deacetylases (HDACs), acetylation of proteins, histones, and transcription factors (TF), myogenic TF factors, and muscle phenotype were assessed in gastrocnemius of mice exposed to periods (1, 2, 3, 7, 15 and 30 days, I groups) of hindlimb immobilization, and in those exposed to reloading for different periods of time (1, 3, 7, 15, and 30 days, R groups) following 7-day immobilization...

OBJECTIVE: Low inhibitory control and strong hedonic response towards food are considered to contribute to overeating and obesity. Based on previous research, the present study aimed at examining the potentially crucial interplay between these two factors in terms of long-term weight loss in people with obesity. METHODS: BMI, inhibitory control towards food, and food liking were assessed in obese adults prior to a weight reduction programme (OPTIFAST® 52). After the weight reduction phase (week 13) and the weight loss maintenance phase (week 52), participants' BMI was re-assessed...

A 59-year-old patient with multiple myeloma on maintenance chemotherapy presented with fever, weight loss and night sweats. An F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) computed tomography (CT) showed intra-abdominal lymphadenopathy with a mesenteric mass that led to further work up and diagnosis of histoplamosis. The patient was treated with amphotericin B and subsequently switched to itraconazole. This exemplifies the usefulness of FDG PET CT in diagnosis of infectious complications...

Society has changed its own lifestyle, specially its eating habits and physical activities, leading to excessive weight and a sedentary behavior, which has contributed to obesity increase. Bariatric surgery is the most effective treatment to obesity, allowing weight loss and its maintenance. However, it has been related high levels of iron deficiency after surgery. A person's nutritional status might be affected by total or partial tooth loss. The aim of this longitudinal prospective cohort study was to evaluate the levels of serum ferritin before and after bariatric surgery and to identify if there is a relation with tooth loss...

Self-management is critical for the prevention and control of chronic health conditions. Research shows that dietary and physical activity behaviors related to obesity are inextricably linked to the development, course, and outcomes of Type 2 diabetes and its comorbidities. Therefore, a compelling case has been made for behavioral lifestyle intervention as the first-line approach. Academic psychologists and other behavioral scientists have contributed to all stages of obesity and diabetes prevention research and practice...

OBJECTIVE: To investigate the role played by leptin in thermoregulation, we studied the effects of physiological leptin replacement in leptin-deficient ob/ob mice on determinants of energy balance, thermogenesis and heat retention under 3 different ambient temperatures. METHODS: The effects of housing at 14 °C, 22 °C or 30 °C on core temperature (telemetry), energy expenditure (respirometry), thermal conductance, body composition, energy intake, and locomotor activity (beam breaks) were measured in ob/ob mice implanted subcutaneously with osmotic minipumps at a dose designed to deliver a physiological replacement dose of leptin or its vehicle-control...

Sepsis is a systemic inflammatory response to pathogens and a leading cause of hospital related mortality worldwide. Sphingosine 1-phosphate (S1P) regulates multiple cellular processes potentially involved in the pathogenesis of sepsis, including antigen presentation, lymphocyte egress, and maintenance of vascular integrity. We thus explored the impact of manipulating S1P signaling in experimental polymicrobial sepsis in mice. Administration of 4-deoxypyridoxine (DOP), an inhibitor of the S1P-degrading enzyme S1P-lyase, or of the sphingosine analogue FTY720 that serves as an S1P receptor agonist after phosphorylation ameliorated morbidity, improved recovery from sepsis in surviving mice, and reduced sepsis-elicited hypothermia and body weight loss...

BACKGROUND: People with schizophrenia are two to three times more likely to be overweight than the general population. The UK National Institute of Health and Care Excellence (NICE) recommends an annual physical health review with signposting to, or provision of, a lifestyle programme to address weight concerns and obesity. The purpose of this randomised controlled trial is to assess whether a group-based structured education programme can help people with schizophrenia to lose weight...
