Morbid obesity is characterized by chronic, low-grade inflammation, which associated with ‘inflamm-aging’. The presence of metabolic syndrome (MetS) might accelerate this phenomenon metaflammation. In study, we assessed the effects morbid and MetS on composition a broad spectrum immune cells present within circulation. A total 117 morbidly obese patients (MOP) without (MetS-), 127 MOP (MetS+) 55 lean controls (LC) were included in study. Absolute numbers T cell, B NK cell monocyte subsets peripheral blood using flow cytometry. Both absolute proportion evaluated correcting for covariates age, body mass index cytomegalovirus serostatus. Although number circulating CD4+ was increased MetS+ group, not influenced MetS. CD8+ compartment contained more differentiated MOP, but affected Even though monocytes as compared to LC, there no difference proportions between three study groups. conclusion, although cells, are obesity-induced system confined phenotype cells.

Background: The present study investigates the impact of oxidative stress after bariatric surgery in patients with obesity. This field has gained great interest recent years due to role that plays metabolic diseases. Obesity, by itself, can generate an increase reactive oxygen and nitrogen species, intensifying cellular damage promoting progression adverse conditions. In this context, emerges as a candidate capable modifying biomarkers, facilitating patient’s recovery. Methods: A systematic review was carried out, identifying 30 studies found databases such PubMed, Scopus, Web Science, Google Scholar. It looked at link between recovery patients. selection based on measurement biomarkers before surgical intervention. Results: results reveal significant decrease surgery. However, notable variability antioxidant activity is observed different patients, well influence comorbidities. Conclusions: Bariatric postulated effective intervention reducing obesity, enhancing improving patient finding highlights importance considering management integral part postoperative care, suggesting need implement complementary treatment strategies optimize health outcomes.

In light of ongoing research elucidating the intricacies obesity and metabolic syndrome, role abdominal fat (especially visceral fat) has been particularly prominent. Studies have revealed that adipose tissue can accelerate development syndrome by releasing various bioactive compounds hormones, such as lipocalin, leptin interleukin. A retrospective analysis was performed on clinical data 167 patients with obesity. Among them, 105 who satisfied predefined inclusion exclusion criteria were included. The parameters evaluated included total area (TAFA), laboratory indicators anthropometric measurements. Weight reduction quantified through percent weight loss (%TWL) excess (%EWL) postoperatively. Binary logistic regression receiver operating characteristic (ROC) curve employed to identify predictors loss. emphasized an independent predictor %EWL ≥75% ( p < 0.001).

Based these results, we formulated a novel model based factors, exhibiting superior predictive value for excellent

Obesity is a big public health problem that claims several thousand lives every year. Bariatric surgery has arisen as suitable procedure for treating obesity, particularly morbid obesity. Oxidative stress, genotoxicity, apoptosis, and inflammatory responses are recognized the most important occurrences in carcinogenesis, they actively contribute to multistep process. This study aimed briefly review connection between oxidative inflammation obese patients undergoing bariatric surgery, focusing on its impact carcinogenesis. Regarding may inhibit synthesis of reactive oxygen species. Moreover, significant reduction status after weight loss was not observed. prevents apoptosis tissues, but maintenance low body long periods mandatory mitigating DNA damage. In conclusion, association cancer risk still premature. However, further studies yet needed elucidate real reduced cancer.

Phloroglucinol (PHG), an analgesic and spasmolytic drug, shows promise in preventing high-fat-diet (HFD)-induced non-alcoholic fatty liver disease (NAFLD) insulin resistance. In Wistar rats, 10 weeks of PHG treatment did not prevent HFD-induced weight gain but significantly mitigated fasting hyperglycemia, impaired responses, steatosis. This protective effect was linked to hepatic lipogenesis or AMP-activated protein kinase (AMPK) activation. Instead, improved mitochondrial function by reducing oxidative stress, enhancing ATP production, increasing anti-oxidant enzyme activity. also relaxed gastric smooth muscles via potassium channel activation nitric oxide (NO) signaling, potentially delaying emptying. A pilot intervention pre-diabetic men confirmed PHG’s efficacy improving postprandial glycemic control altering lipid metabolism. These findings suggest as a potential therapeutic for NAFLD resistance, acting through mechanisms involving protection, activity, motility modulation. Further clinical evaluation is warranted explore full potential.
