Background: Bariatric surgery promotes expressive weight loss, improving the metabolic and inflammatory profiles. The behavior of these indicators in bariatric patients with weight recidivism is unknown. We aimed to investigate both profiles in bariatric patients with high ratio of weight regain (RWR), comparing them with nonsurgical patients with obesity.
Methods: Forty patients with obesity subjected to Roux-en-Y gastric bypass (RYGB) with high RWR composed the bariatric group, and 40 controls matched for BMI, age, and gender were recruited as nonsurgical group. Between-group comparisons were performed for clinical history, physical examination, biochemical, metabolic, and inflammatory profiles.
Results: Bariatric group was composed of a group with an excess weight loss of 85.9 ± 16.8%, a RWR of 56.5 ± 19.7%, and a time since surgery of 10.7 ± 4.3 years. We noticed a lower proportion of patients with type 2 diabetes mellitus and dyslipidemia (P ≤ 0.05) and lower neck and waist circumferences (P ≤ 0.05) in this group. No differences between groups were observed concerning hip circumference, blood pressure, heart rate, total cholesterol, LDL-c, acid uric, creatinine, ALT, ASP, interferon-γ (INF-γ), interferon gamma-induced protein-10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), TNF-α, interleukin-1β (IL-1 β), interleukin-17 (IL-17), and interleukin-10 (IL-10). Of note, fasting glucose; HbA1c; triglycerides; and, surprisingly, IL-6 levels were lower (P ≤ 0.05) in the bariatric group than nonsurgical one while HDL-c level was higher (P < 0.001).
Conclusion: Expressive post-bariatric weight loss, even in patients with high RWR, suggests a possible metabolic benefit/protection in the long term. Probably decreased circulating levels of IL-6 are involved in it.

Background: Obese subjects undergoing weight loss often fear the Yoyo dieting effect, which involves regaining or even surpassing their initial weight. To date, our understanding of such long-term obesity and weight cycling effects is still limited and often based on only short-term murine weight gain and loss studies. This study aimed to investigate the long-term impacts of weight cycling on glycemic control and metabolic health, focusing on adipose tissue, liver, and hypothalamus.

Background: Obesity and metabolic syndrome are major public health concerns linked to cognitive decline with aging. Prior work from our lab has demonstrated that short-term high fat diet (HFD) rapidly impairs memory function via a neuroinflammatory mechanism. However, the degree to which these rapid inflammatory changes are unique to the brain is unknown.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most common chronic liver disease worldwide. The pan-immune-inflammation value (PIV) has been proposed as a biomarker for assessing immune status and inflammation. There is currently no evidence regarding the effect of PIV on the risk of MASLD.

The lack of knowledge about the mechanism of hyperoxia-induced intestinal injury has attracted considerable attention, due to the potential for this condition to cause neonatal complications. This study aimed to explore the relationship between hyperoxia-induced oxidative damage and ferroptosis in intestinal tissue and investigate the mechanism by which hyperoxia regulates inflammation through ferroptosis. The study systematically evaluated the effects of hyperoxia on oxidative stress, mitochondrial damage, ferroptosis, and inflammation of intestinal epithelial cells both in vitro and in vivo.
