Bariatric surgery induces significant weight loss, increases insulin sensitivity, and reduces mortality, but the underlying mechanisms are not clear. It was hypothesized that Roux-en-Y gastric bypass (RYGB) improves metabolic profile along with loss. The objective of this pilot study to evaluate changes in serum metabolites fatty acids (FA) at 2 weeks 6 months after RYGB.Serum samples were collected pre-surgery, post-surgery from 20 patients undergoing RYGB surgery. Serum non-esterified free...

This study aims to investigate the global profiling of genes and miRNAs expression explore regulatory effects eicosapentaenoic acid (EPA) in visceral adipose tissue (VAT) obese mice. We used male mice, fed either a high-fat diet (HF) or HF supplemented with EPA (HF-EPA), for 11 weeks. RNA, small RNA profiling, were performed by RNAseq analysis. conducted analyses using Ingenuity Pathway Analysis software (IPA®) validated candidate related lipid mediators inflammatory pathways qRT-PCR....

Introduction With exponential expansion of Information Technology, the field medical education has embraced innovative electronic learning (e-learning) techniques. The objectives this study were to assess acceptance an integrated e-learning activity by first year students and explore association between pattern computer usage their perception such intervention. Methods A was conducted among (n=95) using a pre-tested validated self-administered questionnaire following interactive which three...

Health at Every Size (HAES) concept promotes health irrespective of weight. This study aimed to determine the correlates HAES alignment in registered dietitians (RDs). Of 246 RDs, 34.1%, 34.6%, 13%, and 18.3% were aligned, somewhat not aligned with HAES, unaware respectively. Weight blame was lower RDs than among others ( P = .001). Alignment associated body mass index, prior weight bias training, practicing management, or implicit > .05). Understanding is important for care individuals higher

This study aimed to explore factors associated with perceived stress in adults higher body sizes. An analysis of data from participants who self-reported weight was conducted (n = 1716). The mean (standard deviation) age 55.92 (15.94) years and 71.3% 28.7% identified themselves as women men, respectively. Gender differences stress, desire for loss, trust physicians, affirmation, discrimination were examined. Perceived significantly than while physicians affirmation men women. Trust both...

Background
 Niger has one of the lowest exclusive breastfeeding (EBF) rates in world. Prelacteal feeding practices may contribute to low EBF rates, but research on barriers related is limited.
 Objective
 The purpose this study was identify socio-cultural determinants for, and to, during an infant’s first 6 months through maternal perspectives Niamey, capital Niger.
 Methods
 Participants were mothers with children aged 0 24 Niger. completed interview including a...

The role of physical activity in normal weight obesity (NWO), which is associated with increased cardiometabolic risk, not clear. This study aimed to determine body composition phenotype-specific differences objectively measured and sedentary time adults the United States. A total 2055 a mass index (BMI) ≥ 18.5 m2 were studied using 2003–2006 National Health Nutrition Examination Surveys.

Our objective was to measure the differences in body composition change following a 6-week early or late time-restricted feeding without specific calorie-targets healthy but sedentary free-living individuals with overweight/obesity. Sedentary, mass index (BMI) of more than 25 kg/m2 were recruited for intervention. They randomized morning fasters (MF) who ate only between 12 pm 8 pm, evening EF 7 am and 3 pm; control group, which instructed continue their usual pattern eating. Specific...

Obesity is characterized by white adipose tissue (WAT) expansion which contributes to chronic diseases such as diabetes and cardiovascular disease. Two main types of are WAT (subcutaneous, SAT visceral tissue, VAT) brown (BAT). These exhibit anatomical, physiological metabolic differences that energy balance, regulation immunity. Our aim was compare transcriptomic microRNA (miRNA) signatures SAT, VAT BAT gain mechanistic insight into the role these depots in disorders. We performed...

Bariatric surgery is known to cause significant weight loss, reduction in insulin resistance, cardiovascular disease and mortality. We hypothesized that adipose systemic inflammation will be decreased post bariatric surgery. Our objective was study changes adipokine levels following recruited patients undergoing Roux En Y gastric bypass laparoscopic band placement. Demographic data both serum tissue samples were collected at the time of surgery, 2 weeks 6 months operatively. Luminex Human...

Serum cystatin C (CysC) is superior to serum creatinine (SCr) in diagnosing mild diabetic nephropathy. We hypothesized that, CysC can predict the risk of CKD progression at an early stage T2DM. Our objective was compare levels CysC, SCr and eGFR T2DM patients no/low with moderate according Kidney Disease Initiative Global Outcomes (KDIGO) guideline’s stratification. Sixty one non‐obese, aged 30‐60 years, suspected were recruited. Creatinine measured using Jaffe method urine. urine albumin...

Obesity is associated with the expansion of adipose tissue that creates a system in which body transitions into prothrombotic and inflammatory state. This part due to an imbalance between reduced levels anti‐inflammatory increased pro‐inflammatory adipokines secreted from tissue, resulting chronic, low‐grade inflammation tissue. Previous studies our laboratory have demonstrated C57BL/6J mice fed high fat diets supplemented omega‐3 fatty acid eicosapentaenoic (HF‐EPA) exhibited lower systemic...
