Effect of biliopancreatic diversion on sleep quality and daytime sleepiness in patients with obesity and type 2 diabetes.

Objective: The poor quality of sleep and the deprivation thereof have been associated with disruption of metabolic homeostasis, favoring the development of obesity and type 2 diabetes (T2DM). We aimed to evaluate the influence of biliopancreatic diversion (BPD) surgery on sleep quality and excessive daytime sleepiness of obese patients with T2DM, comparing them with two control groups consisting of obese and normal weight individuals, both normal glucose tolerant.

Subjects And Methods: Forty-two women were divided into three groups: LeanControl (n = 11), ObeseControl (n = 13), and ObeseT2DM (n = 18).

Long-Term Outcomes of Biliopancreatic Diversion on Glycemic Control, Insulin Sensitivity and Beta Cell Function.

Background: We aimed to assess the long-term outcomes of biliopancreatic diversion (BPD) surgery on glycemic control, insulin sensitivity (IS), and beta cell function using complementary oral and intravenous dynamic tests.

Methods: A total of 57 women were divided into three groups: 19 lean, 18 obese (both groups with normal glucose tolerance (NGT)), and 20 obese with type 2 diabetes who underwent BPD and were reassessed 12 months after the procedure. OGTTs and hyperglycemic clamps (HG) were performed.

Recovery of the incretin effect in type 2 diabetic patients after biliopancreatic diversion.

Context: Bariatric surgery often results in remission of the diabetic state in obese patients. Increased incretin effect seems to play an important role in the glycemic improvements after Roux-en-Y gastric bypass, but the impact of biliopancreatic diversion (BPD) remains unexplored.

Objective: The objective was to elucidate the effect of BPD on the incretin effect and its interplay with beta-cell function and insulin sensitivity (IS) in obese subjects with type 2 diabetes (T2DM).

Epicardial and pericardial fat in type 2 diabetes: favourable effects of biliopancreatic diversion.

Purpose: Ectopic fat is often identified in obese subjects who are susceptible to the development of type 2 diabetes mellitus (T2DM). The ectopic fat favours the decrease in insulin sensitivity (IS) and adiponectin levels. We aimed to evaluate the effect of biliopancreatic diversion (BPD) on the accumulation of ectopic fat, adiponectin levels and IS in obese with T2DM.

Impaired incretin secretion and pancreatic dysfunction with older age and diabetes.

Objective: To estimate the impact of aging and diabetes on insulin sensitivity, beta-cell function, adipocytokines, and incretin production.

Methods: Hyperglycemic clamps, arginine tests and meal tolerance tests were performed in 50 non-obese subjects to measure insulin sensitivity (IS) and insulin secretion as well as plasma levels of glucagon, GLP-1 and GIP. Patients with diabetes and healthy control subjects were divided into the following groups: middle-aged type 2 diabetes (MA-DM), aged Type 2 diabetes (A-DM) and middle-aged or aged subjects with normal glucose tolerance (MA-NGT or A-NGT).

Sagittal abdominal diameter as a marker for epicardial adipose tissue in premenopausal women.

Objective: Accumulation of epicardial (EAT) adipose tissue is associated with the development of an unfavorable metabolic risk profile. Gold standard methods used to assess this fat depot are not routinely applicable in the clinic. Anthropometric measures, including the sagittal abdominal diameter (SAD), have emerged as surrogate markers of visceral obesity.

[Serious jaundice and thyrotoxic myocardiopathy with atrial thrombus].

Jaundice related to thyrotoxicosis and not as an effect of antithyroid drugs is a rare complication that usually occurs in the presence of heart failure (HF) or hepatitis. We report a case of a 54-year-old white woman with hyperthyroidism caused by Graves's disease and jaundice despite methimazole suspension. Bilirubin fluctuated at high values, between 30.

TyG index performs better than HOMA in a Brazilian population: a hyperglycemic clamp validated study.

The TyG index was evaluated as a surrogate method for estimation of insulin resistance (IR). TyG index correlated with adiposity, metabolic and atherosclerosis markers related to IR and presented a moderate degree of agreement with hyperglycemic clamp. TyG index represents an accessible tool for assessment of IR in clinical practice.
