Abstract ‘Imperial Satiety Protocol’ (I‐SatPro) is a new multifaceted approach to weight loss for people with obesity (PwO), encompassing dietary advice, time‐restricted eating, physical activity and coaching to support behaviour change. Participants (n = 84) attended fortnightly I‐SatPro group sessions for 30 weeks, with 70% of participants completing. On completion at 30 weeks, the mean weight loss was 15.2 ± 1.1 kg (13.2 ± 0.8% from baseline, P < .0001), which was maintained to 52 weeks (16.6 ± 1.5 kg, 14.1 ± 1.2%, P < .0001). Weight loss was not associated with reduced energy expenditure. In participants with type 2 diabetes and pre‐diabetes (n = 16), glycated haemoglobin fell from 50 to 43 mmol/mol ( P < .01). Systolic blood pressure fell by 12 mmHg ( P < .0001). Triglycerides fell by 0.37 mmol/L ( P < .01) and high‐density lipoprotein rose by 0.08 mmol/L ( P < .01). Short Form‐36 (SF‐36) functioning and wellbeing scores increased in all domains post I‐SatPro intervention. For selected PwO, I‐SatPro delivers clinically meaningful weight loss, and the potential for long‐term health and wellbeing improvements.
<b>Objective:</b> Roux-en-Y gastric bypass (RYGB) is an established treatment for type 2 diabetes. The study objective was to establish RYGB’s effects on glycaemic variability (GV) and hypoglycaemia. <p><b>Research Design and Methods:</b> Prospective observational study of 10 participants with pre-diabetes/Type 2 diabetes undergoing RYGB, studied before surgery (Pre), 1 month (1m), 1 year (1y) and 2 years (2y) post-surgery with continuous glucose measurement (CGM). A mixed meal test (MMT) was performed at Pre, 1m and 1y. [ClinicalTrials.gov NCT01945840]</p> <p><b>Results:</b> After RYGB, mean CGM glucose fell (at 1m, 1y and 2y), and GV increased (at 1y and 2y). Fifty percent (5/10) of participants exhibited a percentage time in range <3.0 mmol/L [54 mg/dl] (%TIR<3.0) greater than the consensus target of 1% at 1y or 2y. Peak glucagon-like peptide-1 (GLP-1) and glucagon area-under-curve (AUC) during MMT were respectively positively and negatively associated with contemporaneous %TIR<3.0. </p> <b>Conclusions:</b> Patients undergoing RYGB are at risk of developing post-bariatric hypoglycaemia due to a combination of reduced mean glucose, increased GV and increased GLP-1 response.
To investigate whether the elevation in postprandial concentrations of the gut hormones glucagon-like peptide-1 (GLP-1), oxyntomodulin (OXM) and peptide YY (PYY) accounts for the beneficial changes in food preferences, sweet taste function and eating behaviour after Roux-en-Y gastric bypass (RYGB).
Abstract: Hyperuricemia is commonly diagnosed in subjects with abnormal purine metabolism. Prolonged hyperuricemia often associated with gout, which is a vital risk factor for joint dysfunction. The current study was designed to determine the efficacy of vitamin C supplements for treatment of high serum uric acid (UA) among hyperuricemic and gouty patients, and finding-out the effect of supplementation on serum creatinine (Cr) level and glomerular filtration rate (GFR). This intervention study was started in April, 2013, till two months. A convenient sample of 30 adults aged between 24-75 years of both genders was assigned into two study groups: hyperuricemic (n=15) and gouty (n=15) groups. Each participant supplemented with 500 mg/day vitamin C chewable tablets for 2 months. Serum UA, Cr, and GFR were measured before and after treatment. At the end of this study, Cr and GFR enhanced insignificantly in both groups. UA increased insignificantly in gouty group after 2 months by about 0.31 mg/dl. On the other hand, hyperuricemic group showed significant (P ≤0.05) decrease in UA (-0.78 mg/dl) after 2 months duration. In conclusion, supplementation with 500 mg/day vitamin C for 2 months significantly attenuated serum UA for hyperuricemic patients and insignificantly affected serum UA in gouty patients. The uselessness of vitamin C supplements on gouty patients could be associated to a number of possible reasons.
Roux-en-Y gastric bypass (RYGB) is an established treatment for type 2 diabetes and obesity. The study objective was to establish RYGB's effects on glycemic variability (GV) and hypoglycemia.This was a prospective observational study of 10 participants with obesity and prediabetes or type 2 diabetes who underwent RYGB. Patients were studied before RYGB (Pre) and 1 month, 1 year, and 2 years postsurgery with continuous glucose measurement (CGM). A mixed-meal test (MMT) was conducted at Pre, 1 month, and 1 year.After RYGB, mean CGM decreased (at 1 month, 1 year, and 2 years), and GV increased (at 1 year and 2 years). Five of the 10 participants had a percent time in range (%TIR) <3.0 mmol/L (54 mg/dL) greater than the international consensus target of 1% at 1 or 2 years. Peak glucagon-like peptide-1 (GLP-1) and glucagon area under the curve during MMT were positively and negatively associated, respectively, with contemporaneous %TIR <3.0 mmol/L.Patients undergoing RYGB are at risk for development of postbariatric hypoglycemia due to a combination of reduced mean glucose, increased GV, and increased GLP-1 response.
