Roux-en-y gastric bypass (RYGB) surgery is associated with dramatic improvements in obesity-related comorbidity, but also nutritional deficiencies. Vitamin D concentrations are depressed the severely obese, impact of weight loss via RYGB unknown. We determined associations between adiposity and systemic 25-hydroxyvitamin (25(OH)D) during immediate longer-term effects RYGB. Plasma 25(OH)D fat mass (FAT) were by immunoassay air displacement plethysmography, respectively, at 0 (before surgery),...
Summary Background and objectives The significance of renal parenchymal volume the factors that influence it are poorly understood. Design, setting, participants, & measurements Renal (RPV) was measured on contrast-enhanced CT scans after exclusion sinus fat vessels in 224 healthy subjects evaluated as kidney donors a separate cohort 22 severely obese individuals before 6 months weight loss. GFR by iohexol clearance 76 transplant donors. RPV correlated with age, GFR, various...
Obesity-related glucose intolerance is a function of hepatic (homeostatic model assessment-insulin resistance [HOMA-IR]) and peripheral insulin (Si) β-cell dysfunction. We determined relationships between changes in these measures, visceral (VAT) subcutaneous (SAT) adipose tissue, systemic adipocytokine biomarkers 1 6 months after surgical weight loss. HOMA-IR decreased significantly (−50%) from baseline by month further (−67%) months, Si was improved (2.3-fold) Plasma concentrations leptin...
It is not known whether there are mechanisms linking adipose tissue mass and increased oxidative stress in obesity. This study investigated associations between decreasing general abdominal fat depots during weight loss. Subjects were severely obese women who measured serially at baseline 1, 6 (n = 30), 24 months 18) after bariatric surgery. Total (FAT) volumes of visceral (VAT) subcutaneous (SAT) related to plasma concentrations derivatives reactive metabolites (dROMS), a measure lipid...
This cohort study examines the association between COVID-19 pandemic restrictions and obesity prevalence among youths aged 2 to 19 years in Monroe County, Indiana.
Glycemic disorders resolve following Roux-en-Y gastric bypass (RYGB) surgery, but early and longer-term mechanisms regarding effects on β-cell dysfunction as well relationships with decreasing adiposity are not understood. We evaluated longitudinal changes in peripheral insulin sensitivity (Si), the acute response to glucose (AIRg), composite estimate of function, disposition index (DI), over 24 mo via frequently sampled intravenous tolerance testing severely obese women who had fasting...
Resolution of Type-2 diabetes mellitus (DM) after weight loss surgery is well documented, but the mechanism elusive. We evaluated glucose-insulin metabolism patients undergoing a Roux-en-Y gastric bypass (RYGB) using intravenous glucose tolerance test (IVGTT) and compared it with who underwent laparoscopic adjustable band (AB) placement. Thirty-one female (age range, 20 to 50 years; body mass index, 47.2 kg/m 2 ) RYGB. Nine AB placement served as control subjects. All IVGTT at baseline 1...
Recurrence of incisional hernia may be as high 50 per cent. Abnormal collagen I/III ratios have been observed within scar tissue patients with recurrent hernias. We sought to determine whether composition in primary, nonscarred was similarly affected these patients. In this prospective, case-control study, nonscarred, primary abdominal wall skin and fascia biopsies were obtained 12 a history hernias 11 control subjects without any while undergoing laparoscopic surgery. Tissue protein...
Severe acute respiratory syndrome coronavirus 2 is a virus that poses risks to the nutrition status and survival of infected patients, yet there paucity data inform evidence-based quality care.We collected on care provided patients with disease 2019 (COVID-19) by registered dietitian nutritionists (RDNs).Hospitalized COVID-19 (N = 101) in this cohort were older adults had elevated body mass index. The most frequent problems inadequate oral intake (46.7%), energy (18.9%), malnutrition...
Summary Four outer‐membrane proteins of Aeromonas hydrophila were purified and their N ‐terminal sequences channel‐forming properties determined. Three could be matched with from other species. One was a maltoporin, as its level increased when cells grown in maltose‐containing media, the channel it formed blocked by maltose. Another like OmpF OmpC Escherichia coli , except that fluctuated much more rapidly. The third protein, which produced low‐phosphate medium, exhibited several general...
Oral supplementation may improve the dietary intake of magnesium, which has been identified as a shortfall nutrient. We conducted pilot study to evaluate appropriate methods for assessing responses ingestion oral magnesium supplements, including ionized in whole blood (iMg2+) concentration, serum total and urinary content. In single-blinded crossover study, 17 healthy adults were randomly assigned consume 300 mg from MgCl2 (ReMag®, picosized formulation) or placebo, while having...
