The objective of this study is to assess feasibility of the application of an adapted version, with permission, of Dr. Cenk Tek's Simplified Intervention to Modify Physical activity, Lifestyle, and Eating behavior (SIMPLE Program), at Pathways to Housing in Calgary, Alberta. Dr. Tek and his colleagues reviewed the literature and eloquently summarized how individuals with severe mental illness, particularly schizophrenia and schizoaffective disorder are disproportionately affected by obesity and its cardio-metabolic sequelae leading to markedly reduced longevity and increased healthcare costs. Most new antipsychotic medications, which are credited for significant advances in patients' quality of life, appear to induce further weight gain, compounding the problem of obesity and related medical morbidity and mortality. In addition to the weight gain associated with psychiatric medications, sedentary life style, lack of availability of healthy food options, poverty, low level of physical activity, cigarette smoking, and inadequate knowledge or understanding of health maintenance, appear to contribute to the increased obesity rates and poor health in the severely mentally ill. Dr. Tek and colleagues reviewed the available literature on weight loss interventions in individuals with severe mental illness. Despite the overwhelming problems related to obesity, Dr. Tek's team found that research on obesity interventions for persons with schizophrenia is relatively neglected and that there were no treatments that were convincingly shown to be effective for weight reduction in this population with unique needs. Sensing a major societal gap, they decided to create their own weight loss intervention specifically for individuals with severe mental illness. Toward this aim, they collaborated with Dr. Kelly Brownell who created the Lifestyle, Exercise, Attitudes, Relationships, and Nutrition or LEARN Program. This multi-faceted program is designed to promote positive changes in motivation, attitude and deeply ingrained habits that will lead to long lasting weight loss. Brownell's LEARN program is a self-directed weight loss program that empowers the user to make lifestyle changes. Dr. Tek and his colleagues modified and built upon the program by creating the Simplified Intervention to Modify Physical activity, Lifestyle, and Eating behavior or SIMPLE program specifically for individuals with severe mental illness (http://www.simpleprogram.org/). The SIMPLE program is a group weight loss intervention designed for obese patients with schizophrenia or schizoaffective disorder. Dr. Tek and his team piloted their modified weight loss program and published their findings in 2007. Their preliminary study yielded greater weight loss than any of the published randomized controlled trials for a chronic and stable schizophrenia sample, and was the only study to show continued weight loss after the intervention ended. These early results prompted a new larger randomized controlled trial with the largest sample studied to date, an extended period of follow-up, and more detailed testing of the effects of weight loss on schizophrenia symptoms, quality of life, and laboratory markers of obesity related illness risk over a period of up to 16 months. Preliminary results of this trial show significant, sustained weight loss. The goal of this study presented for ethics review, is to apply Dr. Tek's 16-week intervention to a small group of patients at the Pathways to Housing program in Calgary, Alberta. The study coordinator will use Dr. Tek's published manuals, giving full acknowledgment to the authors, to create weekly supportive educational sessions for the group of patients. Three Pathways to Housing staff members, who regularly create education groups for Pathways to Housing patients during a weekly "lifestyle group", will sit in on each session. Weight (to calculate BMI) and waist circumference will be measured weekly. There will be no control group. The proposed feasibility study is designed to fit seamlessly within existing frameworks at Pathways to Housing. Upon completion of the study, we will convene a debriefing session with both the participants and the three Pathways to Housing staff to learn whether patients found the intervention valuable, and whether staff members feel capable of implementing the program on their own going forward. If the program is found to be feasible, the materials created will be available for future use by the multidisciplinary team at Pathways to Housing.
Objective: Study the effect of body position on spirometry in obese patients as defined by waist to hip ratio (WHR) of greater than 0.85 in women, and 0.9 in men Background: Spirometry is routinely ordered to work up dyspnea in obesity. The most common abnormality is a restrictive disease pattern. The underlying mechanisms of this pattern are not completely understood. One plausible explanation is diaphragmatic weakness or skeletal muscle weakness. The change in forced vital capacity (FVC) from sitting to supine is a very sensitive and specific test for detecting diaphragmatic weakness. The effect of body position on spirometry in obesity has not been extensively studied, and there are no studies that look at this when obesity is measured by waist to hip ratio. Effect of body position has been studied in normal patients, and it is expected the FVC can decrease as much as 10% when changing from sitting to supine. The investigators do not know what would be considered 'the normal' amount for FVC to decrease by in the obese population, and thus would like to test patients with increased WHR both in sitting and supine position. The investigators also want to do muscle strength test by measuring the maximal inspiratory and expiratory pressures (MIPs and MEPs). Anticipated results: the investigators anticipate that our study population will replicate the restrictive disease pattern usually seen in obesity. The investigators also anticipate for the FVC to decrease when in the supine position compared to sitting. The amount by which it decreases will likely fall between 10 -25%. The investigators anticipate to not find any abnormalities in MIPs and MEPs in obesity.
The link between metabolic disturbances and vitamin D receptor (VDR) and MEGALIN (or LRP2) gene polymorphisms remains unclear, particularly among African-American adults. The associations of single nucleotide polymorphisms (SNPs) for VDR [rs1544410(BsmI:G/A), rs7975232(ApaI:A/C), rs731236(TaqI:G/A)] and MEGALIN [rs3755166:G/A,rs2075252:C/T, rs2228171:C/T] genes with incident and prevalent metabolic disturbances, including obesity, central obesity and metabolic syndrome (MetS) were evaluated. From 1,024 African-Americans participating in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS, Baltimore, MD, 2004-2013) study, 539 subjects were selected who had complete genetic data as well as covariates selected for metabolic outcomes at two consecutive examinations (visits 1 and 2) with a mean follow-up time of 4.64±0.93y. Haplotype (HAP) analyses generated polymorphism groups that were linked to incident and prevalent metabolic disturbances.
The prevalence of overweight and obesity in Singapore is approximately half of that in the United States, yet the incidence of type 2 diabetes is similar, and is expected to double in the near future. This indicates that metabolic dysfunction, particularly insulin resistance, is widely prevalent even among individuals who are considered normal-weight or lean by conventional measures, i.e. body mass index (BMI) and percent body fat. These individuals are often referred to as "metabolically-obese normal-weight" (MONW), and have increased risk for cardiometabolic disease despite their normal BMI and total body fat values. The prevalence of the MONW phenotype varies across populations and differs markedly among different ethnicities. However, our understanding of the complex interactions between ethnicity, body composition, and metabolic dysfunction and its reversal remains rudimentary. Previous attempts to characterize the MONW phenotype are confounded by the small but significant differences in BMI or percent body fat between groups (even if all subjects were lean, within the "normal" range), with MONW subjects being always "fatter" than the corresponding control subjects. There are no published studies that prospectively recruited groups of metabolically healthy and unhealthy lean individuals matched on BMI and percent body fat. Furthermore, although weight loss improves body composition and many of the cardiometabolic abnormalities in most obese patients, little is known about the possible therapeutic effects of calorie restriction in MONW subjects. Accordingly, a better understanding of the MONW phenotype and the evaluation of therapeutic approaches for its reversal will have important implications for public health. By facilitating earlier identification of these subjects, who are more likely to go undiagnosed and thus less likely to be treated before clinically overt cardiometabolic disease develops, results from this study will allow for earlier and effective intervention.

In line with improvements in oncologic outcome for patients with esophageal cancer, the attritional impact of curative treatment with respect to functional status and health-related quality of life (HR-QL) in survivorship is increasingly an important focus. Functional recovery after surgery for esophageal cancer is commonly confounded by anorexia and early satiety, which may reduce oral nutrient intake with consequent malnutrition and weight loss. One in three disease-free patients has more than fifteen percent body weight loss at three years after esophagectomy. The ESPEN Special Interest Group on cachexia-anorexia in chronic wasting diseases has defined sarcopenia as skeletal muscle index (SMI) of ≤39 cm2/m2 for women and ≤55cm2/m2 for men, while similar cut-off points have been validated in upper gastrointestinal and respiratory malignancies (less than 38.5 cm2/m2 for women and 52.4 cm2/m2 for men). The European Working Group on Sarcopenia in Older People (EWGSOP) additionally recommends that assessment should also include determination of muscle function, for example gait speed or grip strength, where possible. The presence of sarcopenia is associated with increase treatment-associated morbidity, impaired HR-QL, reduced physical and role functioning, and increased pain scores in older adults. In addition, a previous longitudinal study demonstrated that the decline in HR-QL over a six year period in older adults was accelerated in the presence of sarcopenia. As such, sarcopenia may represent a modifiable barrier to recovery and subsequent retention of HR-QL and functional status, and may reinforce a persistent illness identity, among patients following potentially curative treatment for esophageal cancer.
This study is a clinical study to investigate the efficacy of liraglutide compared to placebo in reducing visceral adiposity measured by MRI in overweight or obese subjects at high risk for cardiovascular disease after 40 weeks on-treatment.
The investigators aim to test the protein bioavailability of new specific developed strain of duckweed [Wolffia globose, Mankai] , an aquatic plant, which might serve as a protein source and contains all the 9 essential and the 6 conditional amino acids. The investigators will randomize 36 participants to consume equivalent protein (30gr) content of 3 whole foods items: 1. White cheese (animal protein source, as a reference); 2. Green peas, intact, cooked (plant protein source); 3. Wolffia globosa (Mankai), intact, cooked (plant protein source). The foods will be consumed in the morning, following 12h fasting. The foods will be provided with 250ml mineral water and the blood follow-up frame will be for 3 hours. Primary outcome: Blood amino acid profile.
Mediterranean (MED) diet, richer in plants/seeds (and dietary polyphenols) and low in processed meat (green-MED diet) may have a pronounced beneficial effect on age-related declines that begin in middle age, reflected by changes in adiposity, cognitive function, and cardiometabolic risk. The investigators hypothesize that long-term intake of this diet will significantly potentiate the effects of a healthy lifestyle (physical activity and Mediterranean diet), constituting a powerful strategy to halt or even reverse the progression of several age-related processes related to adiposity, cardiometabolic health and cognition. The investigators further hypothesize that lifestyle intervention might modify the gut microbiota profile and that autologous fecal microbiota supplement derived from the time of maximal weight loss might halt the expected subsequent regain phase.
