Objective: To evaluate the relationship between plasma levels of the inflammatory markers tumor necrosis factor-alpha (TNF-α), C reactive protein (CRP), and interlukin-6 (IL-6) with insulin resistance in Saudi women with polycystic ovaries syndrome (PCOS).
Methods: One hundred eighty Saudi women with and without PCOS, aged 22-38 years, were randomly recruited in this age and body mass index matched case-control study. Clinical assessment, anthropometric measurements, and biochemical parameters were determined for all study participants.
Results: Levels of TNF-α, IL-6, hs-CRP, insulin, and insulin resistance indices were significantly higher among PCOS group than their age and BMI matched controls (p < 0.05). Results showed that only QUICK-I (β = -0.247, p < 0.0001, 95% CI: -3.009 to -0.977) independently predicted TNF-α levels after adjustment for potential confounders.
Conclusions: Elevated plasma levels of TNF- α and IL-6 among PCOS women reflects a state of chronic inflammation with potential implication for insulin resistance, independent of obesity.

Application of attenuated total reflection-Fourier transform infrared spectroscopy in semi-quantification of blood lipids and characterization of the metabolic syndrome.

Background/purpose: Dyslipidemia, a hallmark of metabolic syndrome (MetS), contributes to atherosclerotic and cardiometabolic disorders. Due to days-long analysis, current clinical procedures for cardiotoxic blood lipid monitoring are unmet. This study used AI-assisted attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy to identify MetS and precisely quantify multiple blood lipid levels with a blood sample of 0.

Introduction: Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine-metabolic syndrome mainly characterized by ovarian dysfunction, which is only one manifestation of a more complex syndrome with a significant systemic impact.
Evidence Acquisition: We review scientific literature on the pathophysiology and diagnosis of PCOS evaluating the most relevant data from original articles, reviews and meta-analyses published until June 2024.
Evidence Synthesis: From a pathophysiological point of view, the concurrence of both metabolic aspects, such as insulin resistance and obesity, and hormonal alterations, such as hyperandrogenemia, might produce the most relevant clinical signs and/symptoms of this syndrome, for instance menstrual irregularities, hair loss, acne and hirsutism.
Alpelisib is a phosphatidylinositol 3-kinase inhibitor approved by the US Food and Drug Administration for the treatment of hormone receptor-positive metastatic breast cancer with (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α) mutation. In recent years a number of adverse effects have been observed to be associated with this therapy, the most notable of which is hyperglycemia. A literature search was conducted to include case studies, case series, systematic reviews, and meta-analyses within the last 10 years that evaluated patients with mutated hormone receptor-positive, human epidermal growth factor receptor 2 negative metastatic breast cancer.

Background: Patients hospitalized with moderately severe or acute severe ulcerative colitis (UC) may experience metabolic disturbances, including alterations in insulin resistance due to inflammation and the administration of glucocorticoids (GCs). This pilot study aimed to evaluate insulin sensitivity in patients hospitalized for moderately severe to severe UC.
Method: Patients hospitalized for moderately-severely active UC at Örebro University Hospital, Sweden, were eligible for inclusion.
Metabolic dysfunction associated steatotic liver and kidney stones: what is going on?
Curr Opin Nephrol Hypertens

Department of Urology, University of Alabama at Birmingham, Birmingham, Alabama, USA.
Purpose Of Review: Metabolic dysfunction associated steatotic liver disease (MASLD) is increasing throughout the world, affecting nearly one in three individuals. Kidney stone disease, which is also increasing, is associated with MASLD. Common risk factors for both, including obesity, diabetes, dyslipidemia, hypertension, and metabolic syndrome, are likely drivers of this association.
