Here we investigated cinnamaldehyde (CA) effect on diabetes-induced hypertension. Insulin deficiency was induced by streptozotocin while, insulin resistance by fructose. Rats were left 8 weeks or 12 weeks after STZ or fructose administration respectively. CA (20 mg kg(-1)day(-1)) was daily administered in the last 6 weeks. Then, blood pressure (BP) was recorded. Isolated Aorta reactivity to phenylephrine (PE), KCl, acetylcholine (ACh) was studied as well as nitric oxide (NO) generation plus Ca(2+) influx. Insulin deficiency was associated with elevated BP, increased response to PE and KCl, decreased response to ACh and impaired NO generation. CA treatment prevented hyperglycemia and its associated impaired vascular reactivity. Insulin resistance was associated with elevated BP while, CA prevented this elevation. Insulin resistance increased response to PE and KCl, decreased response to ACh, while CA treatment normalized response to KCl and PE but not to ACh. Insulin resistance was accompanied with reduced NO generation but exaggerated Ca(2+) influx while CA restored normal Ca(2+) influx but did not affect NO generation. In conclusion, CA prevents development of hypertension in insulin deficiency and insulin resistance through normalization of vascular contractility in addition to its insulinotropic effect in insulin deficiency.

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.

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.
