Metastatic fat necrosis is a form of lobular panniculitis which together with synovitis is an unusual complication of pancreatic disease. It can precede an attack of pancreatitis. Pancreatic disease should therefore be remembered as a cause of panniculitis. Serum amylase and abdominal ultrasonography should be considered to exclude pancreatic disease in cases of panniculitis of uncertain etiology. We describe a case of metastatic fat necrosis and discuss the appearance on magnetic resonance imaging.

Hallmarks of Quercetin Benefits as a Functional Supplementary in the Management of Diabetes Mellitus-Related Maladies: From Basic to Clinical Applications.

Quercetin (QE), a particular flavonoid, is well known for its medicinal effects, including anti-oxidant, hypoglycemic, and anti-inflammatory effects. In this review, the findings of QE effects on diabetes STZinduced, alloxan-induced, and its complications have been summarized with a particular focus on in vitro, in vivo, and clinical trials. Consequently, QE mediates several mechanisms, including ameliorating tumor necrosis factor (TNF)-α, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), interleukin (IL)-1β, IL-8, and IL-10 expression, increasing insulin glucose uptake to inhibit insulin resistance.

We investigated the sex-dependent effects of inflammatory responses in visceral adipose tissue (VAT) and perivascular adipose tissue (PVAT), as well as hematological status, in relation to cardiovascular disorders associated with prediabetes. Using male and female hereditary hypertriglyceridemic (HHTg) rats-a nonobese prediabetic model featuring dyslipidemia, hepatic steatosis, and insulin resistance-we found that HHTg females exhibited more pronounced hypertriglyceridemia than males, while HHTg males had higher non-fasting glucose levels. Additionally, HHTg females had higher platelet counts, larger platelet volumes, and lower antithrombin inhibitory activity.

Objective: This study investigates the protective effects of lactic acid, a metabolite of , on non-alcoholic fatty liver disease (NAFLD) induced by a high-sugar, high-fat diet (HFD) in mice, in the context of the gut-liver axis.
Methods: A NAFLD mouse model was established using a HFD, and different intervention groups were set up to study the protective effects of and its metabolite lactic acid. The groups included a control group, NAFLD group, treatment group, Glyceraldehyde-3-P (G-3P) co-treatment group, and NOD-like receptor family pyrin domain containing 3 (NLRP3) overexpression group.
Chest wall perforator flap reconstruction in breast conserving surgery: quality of life and limited complications in outpatient treatment.

Background: Breast conserving surgery (BCS) with partial breast reconstruction (PBR) results in less morbidity, better cosmetic outcomes, and improved patient satisfaction compared to mastectomy. Perforator flap reconstruction can attenuate defects prone to breast deformity after BCS. Usually, postoperative drains and inpatient admission are part of this treatment.

Introduction: We performed a systematic review and meta-analysis to investigate the effects of combining omega-3 polyunsaturated fatty acids (n-3 PUFAs) supplementation with exercise training, as compared to exercise training alone, on body composition measures including body weight, body mass index (BMI), fat mass, body fat percentage, and lean body mass. Additionally, we determined the effects on cardiometabolic health outcomes including lipid profiles, blood pressure, glycemic markers, and inflammatory markers.
Method: Three primary electronic databases including PubMed, Web of Science, and Scopus were searched from inception to April 5th, 2023 to identify original articles comparing n-3 PUFA supplementation plus exercise training versus exercise training alone, that investigated at least one of the following outcomes: fat mass, body fat percentage, lean body mass, triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), systolic (SBP) and diastolic (DBP) blood pressures, fasting glucose and insulin, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α).
