Bariatric surgery (BS) is rarely performed on patients aged 70 and over, due to the fear of adverse effects, particularly related to sarcopenia. We examined the outcome of obese patients who underwent BS after the age of 69 in the French population. Operated subjects were matched with non-operated obese patients (n = 1307 in each group after matching).

Article Synopsis
  • The study aimed to examine changes in lifestyle habits and weight during the COVID-19 lockdown among diabetes patients with overweight or obesity.
  • Participants were surveyed through a web application, revealing that 69.5% of the 5280 surveyed were overweight or obese, with notable lifestyle changes like reduced smoking and healthier eating habits among these individuals.
  • Findings showed that while 18.9% of overweight/obese participants lost weight during the lockdown, a larger portion (28.6%) gained weight, highlighting an opportunity for clinicians to support ongoing healthy changes in future lockdowns.

Background: Obesity is a risk factor for chronic kidney disease (CKD) and a relative contraindication for renal transplantation. Bariatric surgery (BS) is an option to address this issue but we hypothesize that severe CKD is associated with a loss of efficacy of BS which could justify recommending it at an earlier stage of the CKD.

Methods: A retrospective study (n = 101 patients) to test primarily for differences in weight loss at 6 and 12 months according to estimated glomerular filtration rate categories (eGFR < 30 including patients on dialysis, 30-60, 60-90, and ≥ 90 ml/min/1.

Background: Among the population of morbidly obese people, super-super-obese (SSO) individuals (body mass index >60 kg/m) present a treatment challenge for bariatric surgeons.

Objectives: To compare the long-term outcomes between laparoscopic sleeve gastrectomy (SG) and laparoscopic Roux-en-Y gastric bypass (RYGB) and to evaluate the efficacy of SG as a stand-alone bariatric procedure for SSO patients.

Setting: University hospital, Paris, France.

The extent to which microbiota alterations define or influence the outcome of metabolic diseases is still unclear, but the byproducts of microbiota metabolism are known to have an important role in mediating the host-microbiota interaction. Here, we identify that in both pre-clinical and clinical settings, metabolic syndrome is associated with the reduced capacity of the microbiota to metabolize tryptophan into derivatives that are able to activate the aryl hydrocarbon receptor. This alteration is not merely an effect of the disease as supplementation with AhR agonist or a Lactobacillus strain, with a high AhR ligand-production capacity, leads to improvement of both dietary- and genetic-induced metabolic impairments, particularly glucose dysmetabolism and liver steatosis, through improvement of intestinal barrier function and secretion of the incretin hormone GLP-1.

Background: The Paleolithic diet, a diet devoid of food-processing procedure, seems to produce a greater decrease in weight compared to healthy reference diets but its limited food choices make it difficult to implement in our modern times where refined food is dominant.

Objective: To evaluate the effects of a 2-year diet that excludes only six refined foodstuffs implicated in obesity. Professional contact was kept minimal to approximate the approach used by most dieters.

Single-anastomosis duodenoileal bypass with sleeve gastrectomy (SADI-S) is a simplified biliopancreatic diversion. The objective of this study was to develop a reproducible animal model for SADI-S. We used three techniques for duodenal exclusion and duodenoileal anastomosis: (a) surgical clip and side-to-side anastomosis, (b) ligation and side-to-side anastomosis and (c) sectioning the duodenum, closing the duodenal stump and end-to-side anastomosis.

Article Synopsis
  • - The study aimed to explore the link between plasma PCSK9 levels and cardiovascular events in patients with type 2 diabetes, focusing on data from two large cohorts: DIABHYCAR and SURDIAGENE.
  • - Findings indicated that higher PCSK9 levels were associated with increased risk of major cardiovascular events, including myocardial infarction and stroke in the DIABHYCAR cohort, while the SURDIAGENE cohort showed no significant association, especially among high-risk patients on treatment.
  • - The results suggest that the relationship between PCSK9 and cardiovascular events varies based on patient risk levels and treatment types, indicating a need for further research to clarify these inconsistencies.
