This article recommends assessing serum ferritin and vitamin D levels in patients with diffuse hair loss before starting treatment, but it reports no new clinical results.

This study found that lower serum melatonin levels were associated with increased skin aging grades among individuals in Ulaanbaatar, suggesting melatonin loss may contribute to earlier skin aging.

This study found that the risk of urinary stone disease increased significantly in patients with severe androgenetic alopecia, and that testosterone deficiency was more frequent among these patients.

In this study, researchers found that many infant formulas in Japan lack sufficient biotin, putting infants at risk of developing nutritional biotin deficiency.

This case report describes an 11-year-old girl who experienced hot flashes and menarche after taking a Serenoa repens supplement for telogen effluvium, suggesting a possible but uncertain link between the supplement and hormonal changes.

This study found that serum testosterone levels significantly increased during major head and neck surgeries in maxillofacial surgeons, influenced by factors like tumor size and procedural complexity.

This study found higher mean zinc levels in the hair of cystic fibrosis patients with growth retardation compared to those with normal growth.

In this review, researchers evaluated sericin-based drug delivery systems for antimicrobial, anticancer, and neurodegenerative treatments, highlighting its potential benefits and challenges related to molecular variability and formulation stability, suggesting future focus on optimizing extraction and integration with advanced biomedical technologies.

Vitamin D and zinc may help treat alopecia areata.

This study developed and validated a highly sensitive method using ultrahigh-performance liquid chromatography with tandem mass spectrometry for accurately analyzing nine neuroactive steroids in human serum, which could enhance understanding of disease pathophysiology and support new biomarker and therapeutic discovery.

This review notes that while ATX-101 showed a favorable safety profile for reducing submental fat in clinical trials, serious adverse events related to procedures have been reported in real-world use, prompting recommendations for improved management and prevention strategies.

This study developed a mathematical model and online tool using serum AMH, androstenedione levels, UML, and BMI to screen for undiagnosed PCOS, particularly useful for Asian populations.

This study concluded that among men with normal testosterone levels, a small increase in serum dihydrotestosterone may reduce symptoms of hypogonadism, suggesting its potential diagnostic use after ruling out hypogonadism.

This study found that vitamin D deficiency was significantly more common in alopecia areata patients than in healthy controls and was inversely correlated with disease severity.

This study concluded that PCOS patients, regardless of weight, have significantly lower serum amylin levels than healthy BMI-matched controls, while serum preptin levels did not vary significantly between groups.

This study found that oral pulse steroids significantly reduced serum and tissue levels of TNF-α in patients with alopecia areata, correlating with clinical improvement.

In this review and meta-analysis, the authors concluded that 5α-reductase inhibitor therapy is not consistently associated with significant increases in serum testosterone levels in men.

This study found that women with polycystic ovary syndrome have higher triglyceride and fasting glucose levels in obese individuals and higher total cholesterol levels in non-obese individuals compared to healthy women.

This study found no significant correlation between vitamin D levels and disease severity in alopecia areata patients, highlighting the need for further research on vitamin D supplementation's effects.

This case study describes a 15-year-old girl with a Sertoli–Leydig cell tumor who showed high androgen levels and steroidogenic responses similar to patients with polycystic ovary syndrome before surgery.

This case report observed that an adolescent female experienced hair loss with fluoxetine and sertraline, which resolved with venlafaxine, suggesting potential alopecia as an adverse reaction to these SSRIs.

In this study, Ser516 phosphorylation of Artemis was found predominantly in the outer root sheath keratinocytes of hair follicles, suggesting a role in regulating human epidermal appendages.

This study found no significant association between premature hair graying and serum ferritin or vitamin D levels in young adult males at Universitas Sumatera Utara.

This study found that the FSHR Ser680Asn (rs6166) gene polymorphism is associated with an increased risk of PCOS in the examined population and could serve as a molecular biomarker for identifying risk.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

This study found that serum steroid profiling, particularly 11-deoxycortisol, can effectively differentiate between ACC and ACA, while considering sex differences and functional status for other steroids is important.

In this study using the TriNetX Research Network, men with low serum testosterone levels were found to have an increased risk of developing an initial kidney stone, particularly in those aged 33-44, compared to men with normal testosterone levels.

This study found that in patients with severe aortic valve stenosis, higher serum dihydrotestosterone levels were associated with increased myocardial hypertrophy, fibrosis, and reduced left ventricular function.

This study found that elevated serum AMH levels can be a strong predictor for diagnosing PCOS among women of reproductive age, when used alongside the other Rotterdam criteria.
