10, P = 0.044) independent of age, sex, ethnicity, types of surgery, diabetes condition, preoperative BMI, and follow-up period.

Among patients with severe obesity, TL in leukocytes and adipose tissue was highly correlated. However, there was variability in the association of TL in these tissues with weight loss after surgery.

This study aimed to determine the impact of weight gain prevention interventions on changes in cardiovascular risk factors over 6 years.

The Study of Novel Approaches to Weight Gain Prevention (SNAP) randomized 599 participants (ages 18-35; 46% with BMI 21-25; 54% with BMI 25-30) to Large Changes (produce buffer by losing 5-10 pounds initially), Small Changes (daily small changes in intake and activity) or Control and followed 355 participants with ongoing intervention and assessments through 6 years.

There were no significant differences among interventions for changes in weight or cardiovascular disease (CVD) risk factors from baseline to 6 years. However, 44% of participants gained ≥5%, and only 14% lost ≥5% over 6 years. Weight changes, from baseline to year 6, were significantly associated with changes in risk factors, especially insulin and high-density lipoprotein cholesterol. Earlier weight changes (e.g., weight cycling) had no beneficial or adverse effect on changes in CVD risk factors at 6 years, independent of 6-year weight changes.

Despite participation in a weight gain prevention trial, almost half of these young adults gained ≥5% or more over 6 years, with significant worsening in CVD risk factors. Sulbactam pivoxil supplier Greater attention to long-term weight gain prevention in young adults is needed.

The purpose of this study was to examine whether the degree of ketosis, measured as plasma β-hydroxybutyrate (βHB) in fasting, was associated with changes in appetite feelings and plasma concentration of appetite-related hormones after weight loss.

A total of 87 individuals with obesity (BMI 36.5 ± 4.0 kg/m
; age 42.4 ± 9.7 years; 39 males) underwent 8 weeks of a very low-energy diet. Body weight/composition, plasma concentration of βHB, and appetite-related hormones (active ghrelin, active glucagon-like peptide 1 [GLP-1], total peptide YY, cholecystokinin [CCK], and insulin) and subjective appetite feelings were measured at baseline and week 9.

Participants lost 17.7 ± 4.1 kg and were ketotic (βHB 1.24 ± 0.82 mmol/L in fasting) at week 9. A negative association was found between βHB in fasting at week 9 and changes in basal (r = -0.315, P = 0.003) and postprandial ghrelin concentration (r = -0.286, P = 0.008), and a positive association was found with the change in postprandial GLP-1 (r = 0.244, P = 0.025) and CCK (r = 0.228, P = 0.035). No association was seen between βHB in fasting and changes in peptide YY or subjective feelings of appetite.

βHB plasma concentration in fasting is associated with lower concentrations of the hunger hormone ghrelin and increased concentrations of the satiety hormones GLP-1 and CCK. Future studies should explore the molecular mechanisms by which βHB modulates the secretion of gut hormones.

Following metabolic and bariatric surgery (MBS), most adolescents experience weight loss and improvement of many obesity-associated complications (OACs). The relationship between weight loss and remission of OACs after MBS in adolescents has not been well described.

The Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) is a multi-institutional prospective observational study of adolescents who underwent MBS between 2007 and 2012. Lower-weight-loss responders (LWLRs) were defined as having <20% total body weight loss (TBWL) and higher-weight-loss responders (HWLRs) were defined as having ≥20% TBWL at 5 years after MBS. The prevalence of OACs was compared at baseline and 5 years after MBS.

Both LWLRs (n = 114) and HWLRs (n = 78) lost significant weight within the first year following MBS; however, the TBWL at 5 years for the LWLRs was 8.6% ± 9.5% compared with 33.8% ± 9.2% for the HWLRs. Those in the HWLR group were more likely to experience durable remission of composite dyslipidemia at 5 years, whereas there were no differences between groups in remission rates of all other OACs.

Greater weight loss after MBS in adolescents was associated with greater remission of composite dyslipidemia; however, remission of other OACs was not dependent on major sustained weight loss.

This study aimed to evaluate (1) the effectiveness, complications, and postoperative access to transplantation in end-stage chronic kidney disease (ECKD) and (2) the effectiveness and complications of bariatric surgery in patients who had already undergone kidney transplant.

A systematic review and meta-analysis of mortality and complications rates were performed. Thirty studies were reviewed.

After bariatric surgery, patients with ECKD had similar postoperative weight loss to patients from the general population. Meta-analysis showed post-bariatric surgery rates of 2% (95% CI 0%-3%) for mortality and 7% (95% CI 2%-14%) for complications. Approximately one-fifth of the patients had access to a transplant. This rate may be underestimated because of the short duration of follow-up. The lack of control groups did not allow for a conclusion on the role of bariatric surgery in facilitating access to kidney transplantation. In patients who had received a kidney transplant, bariatric surgery seemed to improve renal function but increased graft-rejection risk, possibly because of changes in the bioavailability of immunosuppressant drugs.
