Objective: This study aimed to examine whether pregnancy following bariatric surgery affects long-term maternal weight change and offspring birth weight.
Methods: Using data from the Longitudinal Assessment of Bariatric Surgery (LABS)-2 study, linear regression was used to evaluate percent change in total body weight over a 5-year follow-up period among reproductive-aged women who underwent Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding as well as evaluate the association of bariatric procedure type and offspring birth weight.
Results: Of 727 women with preoperative age of 36.1 (6.3) years (mean [SD]) and BMI of 46.9 (7.0) kg/m , 80 (11%) reported at least one pregnancy. After adjusting for covariates, percent change in total body weight was not significantly different between women who became pregnant and those who did not during a 5-year follow-up period (β = 2.02; 95% CI: -1.03 to 5.07; P = 0.19). Additionally, mean birth weight was not significantly different between mothers who underwent Roux-en-Y gastric bypass versus laparoscopic adjustable gastric banding (P = 0.99).
Conclusions: Postoperative pregnancy did not diminish long-term weight loss in women in the LABS-2 study. The finding of comparable weight loss is relevant for providers counseling women of reproductive age on weight-loss expectations and family planning following bariatric surgery.

Background: Cholesterol efflux capacity (CEC) of HDL (high-density lipoprotein) is inversely associated with incident cardiovascular events, independent of HDL cholesterol. Obesity is characterized by low HDL cholesterol and impaired HDL function, such as CEC. Bariatric surgery, including Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), broadly leads to improved cardiovascular outcomes, but impacts on risk factors differ by procedure, with greater improvements in weight loss, blood pressure, and glycemic control after RYGB, but greater improvements in HDL cholesterol and CEC levels after SG.

Metabolic and bariatric surgery (MBS) has been associated with weight reduction and obesity complications improvement. However, there is no clear evidence of the extent and consistency of the effects of this procedure on rheumatic diseases. This study aims to conduct a meta-analysis to address the impact of MBS on rheumatic diseases.

Background: Genetic background of severe obesity is inadequately understood. The effect of genetic factors on weight loss after metabolic bariatric surgery (MBS) has shown inconclusive results.
Objectives: To determine the prevalence of rare obesity-associated gene variants in a secondary analysis of a randomized clinical trial (RCT) comparing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) for the treatment of severe obesity and examine their association with long-term weight loss at 10 years.

Background: The successful weight loss following bariatric surgery is not achieved in all patients with morbid obesity (MO). This study aims to determine whether a serum miRNA profile can predict this outcome.
Design: Thirty-three patients with MO were classified in "Good Responders" (GR, percentage of excess weight loss (%EWL) ≥ 50 %) or "Non-Responders" (NR, %EWL < 50 %) according to the %EWL 5-8 year following bariatric surgery.

Introduction: Obesity, defined as a body mass index ≥30 kg/m, is a major public health concern in the United States. Preventative approaches are essential, but they are limited by an inability to accurately predict individuals at highest risk of weight gain. Our objective was to develop accurate weight gain prediction models using the National Institutes of Health All of Us dataset.
