Leptin is a protein hormone produced mainly by obese gene and secreted by adipose tissue and exerts the biological effects through leptin receptors. With the progress in research on the function and receptor signal transduction related leptin and leptin resistance, it has been found that leptin is associated with the development and progression of many cardiovascular diseases, such as hypertension and left ventricular hypertrophy. Some studies have reported that leptin resistance is the pathologic basis for a variety of cardiovascular diseases. This paper will briefly review the advances in the study of correlation between leptin and hypertensive-left ventricular hypertrophy (HLVH), focusing on the relationship between leptin and various factors related to HLVH, such as sympathetic nervous system, renin angiotensin aldosterone system, growth factors, inflammatory factors and insulin resistance.

Recent studies have suggested that the interaction between diet and an individual's genetic predisposition can determine the likelihood of obesity and various metabolic disorders. The current study aimed to examine the association of dietary branched-chain amino acids(BCAAs) and aromatic amino acids(AAAs) with the expression of the leptin and FTO genes in the visceral and subcutaneous adipose tissues of individuals undergoing surgery. This cross-sectional study was conducted on 136 Iranian adults, both men and women, aged ≥18 years.

Pubertal gynecomastia (PG) is a common condition characterized by the abnormal development and hyperplasia of unilateral or bilateral breast tissue in adolescent males, affecting up to 50% of appropriately aged adolescents and exhibiting rising prevalence over recent years. The etiology of PG is multifaceted, encompassing physiological, pharmacological, and pathological factors. This narrative review synthesizes evidence from a comprehensive selection of peer-reviewed literature, including observational studies, clinical trials, systematic reviews, and case reports, to explore the pivotal role of endocrine hormones in the pathogenesis of PG.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.

The chronotype, the personal predisposition towards morning or evening activities, significantly influences health conditions, sleep, and eating regulations. Individuals with evening chronotypes are often at a higher risk for weight gain due to misalignment between their natural tendencies of functioning and social schedules, resulting in insufficient sleep, disruptions in eating habits, and decreased physical activity levels. Often, impaired glucose tolerance and changes in melatonin, adiponectin, and leptin secretion, along with alterations in the clock gene functions in subjects with evening preferences, may be predisposed to obesity.
