Therapeutic Modulation of Nitric Oxide Pathways to Address Insulin Resistance in Cardiovascular–Kidney–Metabolic Syndrome

Ligia-Maria Ceteraș, Vlad Dumitru Brata, Ioana Dobrotă, Rahela Borbei et autres

Cardiovascular-kidney-metabolic (CKM) syndrome encompasses the convergent pathophysiology of obesity, insulin resistance, type 2 diabetes, chronic kidney disease, and cardiovascular disease, conditions whose interactions account for a substantial proportion of cardiovascular morbidity and mortality despite contemporary guideline-directed therapy. Nitric oxide (NO) pathway dysfunction …

Metabolic Syndrome and Pancreatic Cancer: Linking Insulin Resistance, Inflammation, and Carcinogenesis

Rahela Borbei, Vlad Dumitru Brata, Ioana Dobrotă, Ligia-Maria Ceteraș et autres

Metabolic syndrome (MetS) is a composite classification defined by heterogeneous combinations of cardiometabolic abnormalities. Several components have been associated with pancreatic cancer (PC), but studies often conflate long-term metabolic exposure, tumor-related prediagnostic metabolic change, and prognosis after diagnosis. This review critically evaluates …

Neuroendocrine Disruption of Reproduction by Bisphenols and Phthalates: From Molecular Mechanisms to Reproductive Outcomes

Codruța Claudia Gherman Lencu, Cezara-Andreea Gerdanovics, Olga Hilda Orasan, Ioana Iancu et autres

Bisphenols and phthalates are ubiquitous endocrine-disrupting chemicals with potential effects on reproductive neuroendocrine regulation, particularly during sensitive developmental windows. This review summarizes current evidence on their exposure profile, mechanisms of reproductive disruption, and female- and male-specific reproductive adversities. A structured narrative review …

Oxidative Stress Biomarkers and Their Association with Interleukin-6 in Patients with Obstructive Sleep Apnea: A Cross-Sectional Study

Crina Veronica Zinveliu (Bercian), Dan Claudiu Măgureanu, Raluca Maria Pop, Adela Sitar-Tăut et autres

Oxidative stress and systemic inflammation are considered key mechanisms linking obstructive sleep apnea (OSA) to cardiovascular disease. This study aimed to investigate the relationships among oxidative stress, nitrosative stress, inflammatory biomarkers, and echocardiographic alterations in OSA. This cross-sectional observational study included 72 …

Obstructive Sleep Apnea and Arrhythmia: A Narrative Review of Arrhythmogenic Mechanisms

Crina Veronica Zinveliu (Bercian), Adela Sitar-Tăut, Angela Cozma, Elena Buzdugan et autres

Obstructive sleep apnea (OSA) constitutes a chronic disorder characterized by recurrent upper airway collapse during sleep. This condition is prevalent among patients with cardiac rhythm disturbances and represents a potent independent risk factor for arrhythmia. Although most studies have concentrated on the …
