Filter by:Healthy for Two, Healthy for You (H42/H4U) is an innovative evidence-based pregnancy/postpartum health coach intervention that is remotely-delivered (phone coaching using motivational interviewing, web-based platform, mobile phone behavioral tracking). The aim of this randomized controlled trial (RCT) is to embed H42/H4U into Johns Hopkins prenatal care clinics that serve a racially and economically diverse population, leveraging existing staff as trained health coaches to test its effectiveness and implementation. The investigators hypothesize that women in the H42/H4U arm will have lower gestational weight gain and lower rates of gestational diabetes, without an increase in low birth weight infants, and that implementation into the investigators' prenatal care clinics will be feasible and scalable.
The obesity epidemic is a major public health problem. Weight gain is strongly associated with an increase in the incidence of complex health conditions such as type 2 diabetes (T2D), cardiovascular disease, stroke, and cancers. Behaviours linked to food and beverage consumption can greatly affect body weight. Frequent consumption of sugar-sweetened beverages such as carbonated soft-drinks, energy and sport drinks, fruit juices from concentrate, soda and flavoured milk and water is considered to be an unhealthy dietary behaviour. This project will investigate how variations in an individual's genes may impact their consumption of SSBs and thus body fatness. Specifically, the project will aim to investigate whether genetic variation in the taste receptors TAS1R2 and TAS1R3 can influence an individuals' perception and liking of a sweet palate and their intake of SSBs in UK. This study will be an experimental study that evaluates human body composition by different measurements. Additionally, two different biomarkers will be used for the study, such as blood and urine samples. Blood samples are the preferred source for DNA testing, rather than saliva. Urine samples will be used to look at the sugar level in the human body as a measure of body composition using deuterium dilution techniques. Around 128 adult volunteers will be recruited from Aberdeen, UK to participate in the study, which will take approximately one week to complete for each individual.
The detrimental effect of overweight and obesity on fecundity has been well documented. The investigators wish to investigate the intervention program for weight loss before fertility treatment. Subsequently to gain knowledge on the effect of overweight/obesity and weight loss on the vaginal microbiome, on DNA damage on sperm cells, on the occurrence of endocrine disruptors in the endometrium, and on the gene expression in the endometrium.
This is an interventional research study about clinical, psychosocial, and behavioral factors that impact weight loss, weight maintenance, and cardiovascular disease in socially disadvantaged persons.
The use of dietary amino acids has been explored for therapeutic and safety intervention of obesity and obesity-induced dysfunction. In particular, 3 molecules have been shown to be effective both in the animal model and in humans, in promoting the loss of fat mass, specifically visceral adipose tissue, and in maintaining free fat mass: arginine, glutamine and leucine (and its metabolite beta hydroxy methyl butyrate, HMB). The aim of this study was to evaluate the efficacy in terms of fat mass, in particular Visceral Adipose Tissue reduction, as primary end point, in obese patients following the administration of specific food for special medical purposes (FSMP) for muscle recovery, consisting of arginine, glutamine and HMB. The secondary end point is the evaluation of skin state, by a validate self-reported questionnaire survey to assess skin, after 4- weeks intake of this FSMP.
Increased body weight leading to the development and the establishment of overweight and obesity, has a growing detrimental effect on overall health status and quality of life. Latest research has been focusing on the direct influence of dietary habits on body weight regulation and its synergistic effect with genetic predisposition. The synergistic effect of genetic makeup and dietary habits constitute a major contributing factor, specifically in its manifestation on parameters of the cardiometabolic profile of individuals with elevated body weight. In this context, the aim of the present study is to investigate the effect of two hypocaloric diets with different macronutrient content (a high-carbohydrate/low-fat and a high-protein one) on the body weight loss of an overweight and/or obese adult, Greek population. Moreover, the study aims to explore gene-diet interactions between obesity and weight loss- related target genes and adherence to the proposed dietary schemes. It will further examine influences of the aforementioned factors on body composition, anthropometric indices, such as waist circumference, biochemical biomarkers related to cardiometabolic control and parameters of lifestyle, such as sleep quality. More specifically, 300 participants will be allocated into two groups, following either the high-carbohydrate/low-fat diet or the high-protein diet, for a duration of 3 months. Volunteers will participate in in-person meetings, at baseline and at three months after the beginning of the intervention. Anthropometric measurements and collection of blood samples will take place in each meeting. Demographic data and data on family and medical history, dietary habits, adherence to the Mediterranean diet, overall health status and physical activity will be collected at baseline. Participants will be provided with nutritional counselling and support both at the beginning and throughout the intervention. Participants will further report their monthly progress by completing online questionnaires (namely concerning their body weight, overall health status, physical activity and sleep quality), via use of an online assessment tool developed by our team. The effect of the intervention will be evaluated using anthropometric indices, body composition markers and biochemical biomarkers of cardiometabolic control, pre- and post- intervention. Gene-diet interactions will be assessed via genotyping of DNA samples and statistical analyses will take place via statistical packages, such as PLINK v.1.9.
This study employs a placebo-controlled randomized cross-over design to investigate the impact of body weight and aspirin dose on levels of specialized pro-resolving lipid mediators in blood and neutrophils.
The study consists of two arms: 1) intervention group using eggs as supplementary food given from 2nd trimester of pregnancy to birth, and 2) observational group of pregnant mothers. it aims to assess the effectiveness of improving dietary quality during pregnancy on the epigenetic and stunting related outcomes (growth and development) in infants, who will be followed up until 24 months old

Pancreas transplantation is currently the most reliable method for glycemic control in insulin dependent diabetic patients. Outcomes of pancreas transplantation have improved significantly over the years due to improved surgical techniques, medical management and immunosuppression. However, weight gain after pancreas transplantation remains a common problem with associated consequences such as development of type 2 diabetes, coronary artery disease, graft loss, metabolic syndrome and increased risk of cardiovascular death. Excessive weight gain is well known after liver and kidney transplantation; however there are very few studies that have looked at weight gain after pancreas transplantation. In a recent study by Knight et al, 26% of the pancreas transplant recipients had excessive weight gain, defined as more than 30% of their baseline weight by 1-year post transplant. The study focused mainly on the endocrine function of the pancreas, explaining that excessive peripheral insulin circulation post-transplant may explain the weight gain. Other factors like immunosuppression, increased oral intake and potentially reduced activity may also have played a role. However no study has looked at the possible role of exocrine secretion from the new pancreatic allograft, combined with exocrine secretion of the old pancreas, leading to excessive availability of digestive juices like trypsin, chymotrypsin, lipase, amylase, gelatinase, elastase etc. Our hypothesis is that the excessive weight gain after pancreas transplant, which is more than in other solid organ transplants, is driven by the excessive digestive juice leading to improved conversion of available food and nutrient into storable energy and subsequently leading to weight gain. The patient will therefore need to either increase physical activity to avoid weight gain post-transplant or significantly reduce caloric intake. Fecal elastase test (FE-1)-elastase is a proteolytic enzyme produced by pancreatic acinar cells. They bind to bile salt and pass through the gut without degradation. These levels correlate well with the other pancreatic enzyme levels. Fecal elastase concentration (FEC) has been used routinely to screen for pancreatic exocrine insufficiency (PEI). Exocrine pancreatic juice has been a target for the management of obesity lately, with the use of drugs like Orlistat (Xenical) that inhibits pancreatic lipase and therefore interfere with the absorption of fat. If our theory of excessive pancreatic juice availability after pancreas transplant can be proven, it can help guide the targeted use and appropriate dosing of such drugs based on the level of the pancreatic juice as measured by the FEC.
