Background/objectives: Psoriasis is a chronic dermatological condition with systemic implications, especially with metabolic syndrome (MS). This study evaluated the vicious cycle where obesity and MS exacerbate systemic inflammation that complicates the efficacy of psoriasis therapies by examining the PASI score over a one-year period. Patients were classified into two subgroups: those with psoriasis alone (PSO) and those with both psoriasis and metabolic syndrome (PSO-MS).

Methods: A total of 150 patients, half of whom also concomitantly presented with metabolic syndrome, received biologic therapies comprising anti-IL-17, anti-IL-23, and anti-TNF-a, or methotrexate, with PASI scores assessed at baseline and at 3, 6, and 12 months.

Results: All treatments showed significant reductions in PASI; however, patients with PSO showed more marked reductions in PASI score than those in the PSO-MS group. Anti-IL-17 treatments produced the greatest sustained long-term improvements, whereas anti-IL-23 produced prompt early improvements. Increases in BMI and leptin concentrations were associated with a modest rate of reduction in PASI score, underlining the impact of obesity and metabolic dysfunction on treatment efficacy.

Conclusions: This study highlights the importance of managing comorbidities such as MS in the treatment of psoriasis, as the interplay between systemic inflammation and metabolic health further complicates therapeutic outcomes.

Cardiovascular-kidney-metabolic (CKM) syndrome is the association between obesity, diabetes, CKD (chronic kidney disease), and cardiovascular disease. GDF-15 mainly acts through the GFRAL (Glial cell line-derived neurotrophic factor Family Receptor Alpha-Like) receptor. GDF-15 and GDFRAL complex act mainly through RET co-receptors, further activating Ras and phosphatidylinositol-3-kinase (PI3K)/Akt pathways through downstream signaling.

To examine the changes in obesity-related hormones and metabolic syndrome markers in male high school students with obesity following a weekend-focused moderate- or high-intensity exercise program at the recommended weekly physical activity level, or a program of regular exercise 3 times a week at moderate intensity, over a 10-week period. Forty-eight male high school students who were obese with a body fat percentage of ≥25% were randomly assigned to one of three groups: a regular moderate-intensity exercise group (n=17) that freely selected and performed moderate-intensity aerobic and resistance training exercises, every Monday, Wednesday, and Friday, for a total of 150-300 min/wk; a weekend-focused moderate-intensity exercise group (n=15) that freely selected and performed aerobic and resistance training exercises every Saturday for 150-300 min; and a week-end-focused high-intensity exercise group (n=16) that freely selected and performed aerobic and resistance training exercises every Sunday for 75-150 min. Insulin and leptin levels significantly decreased in all the groups, with the greatest reduction in the regular exercise group.

Metabolic-dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease in the Western world. MASLD-associated cirrhosis prevalence is on the rise along with the obesity and metabolic syndrome epidemic. Genetic factors are included in the multi-hit model of MASLD pathogenesis and insulin-like growth factor-1 (IGF-1) has an important role.

Introduction  Diabetes is a rapidly growing global health concern, with the World Health Organization (WHO) estimating that 300 million adults will have diabetes by 2025. This chronic condition is associated with complications, including nephropathy, retinopathy, neuropathy, cardiovascular disease, and diabetic foot ulcers (DFUs), which can lead to amputation. Diabetic septic foot (DSF), a severe form of diabetic foot disease, is defined by the WHO as the presence of infection, ulceration, or tissue destruction in the lower limb, often accompanied by neurological abnormalities, peripheral vascular disease, and metabolic complications of diabetes.
