Vitamin D deficiency is common in women with PCOS and linked to some metabolic problems, but not the main cause of their metabolic issues.

In this study, researchers reported that a newly developed interferon-γ release assay for cell-mediated immunity to SARS-CoV-2 nucleocapsid peptides demonstrated high sensitivity and specificity, making it a robust tool for routine diagnostic tests and potentially useful in predicting clinical outcomes after pathogen re-exposure.

This review of 32 articles suggests a stronger association between alopecia areata and allergic rhinitis than asthma in both adults and children, indicating a potential Th2-mediated component.

This review suggests that radiofrequency devices may be effective for both hair removal and growth, depending on the RF modality, but further research is needed to clarify their efficacy and mechanisms.

This study found that individuals with a recent history of suicide attempts exhibited altered DHEA hair levels, suggesting possible dysregulation of the HPA axis as a biopsychosocial feature, and recommends further investigation into hair hormones as potential markers of suicidal crisis and vulnerability.

Green tea in shampoo can help hair grow, get stronger, control dandruff, and is good for fine hair.

EGF receptors are crucial for skin cell growth and decrease with age.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This review examines complementary and alternative medicine for alopecia and finds limited support from robust clinical trials, highlighting the need for standardized studies to evaluate efficacy and safety.

This study found that trichorrhexis nodosa, a cause of unexplained hair loss, is often linked to mechanical trauma rather than a metabolic defect.

This study found that the activation of ER‑β increased keratinocyte proliferation and gene expression related to epidermal regeneration, enhancing wound healing in both cell models and rats.

In this study, the researchers found that constitutive activation of the EGFR in mice led to increased sebum production, enlarged sebaceous glands, and altered gene expression related to sebocyte proliferation and lipogenesis.

This review examines the cognitive effects of medications for lower urinary tract symptoms and indicates that muscarinic antagonists, particularly oral oxybutynin, pose the highest risk for cognitive impairment.

In a swine model, this study found that a novel micro-coring needle device increased skin thickness and collagen content, suggesting potential as a safer, cost-effective alternative to laser resurfacing for skin rejuvenation.

In this study, the researchers discovered that specific polyamine depletion enhances stemness in hair follicle stem cells through a mechanism independent of mRNA translation.

This study found that low serum testosterone and elevated serum oestrone in men with cirrhosis are associated with worse liver disease and adverse health outcomes, suggesting oestrone as a potential ill health marker.

This review explores the role of neutrophil recruitment in the inflammation seen in hidradenitis suppurativa and emphasizes potential therapeutic targets within these pathways, but it reports no new clinical results.

This article discusses suspected skin toxicity from drugs used to treat rheumatoid arthritis but reports no new clinical findings.

This study found that deslorelin implants can effectively reduce estradiol levels and support hair regrowth in neutered ferrets with hyperoestrogenism caused by nodular hyperplasia of the adrenocortex.

This study found that minoxidil significantly reduces systemic blood pressure and vascular resistance in patients with hypertension, but does not alter pulmonary vascular resistance or exacerbate pulmonary hypertension.

This article reviews current diagnosis and treatment approaches for diabetes in adolescents, emphasizing a team-based management strategy, but provides no new clinical findings.

This review explores the crucial role of regulatory T cells in skin wound healing, emphasizing their involvement in balancing immune responses and promoting regeneration. It also discusses Tregs' operations in fibrosis, keloidosis, and scarring, suggesting a potential avenue for novel treatments.

This study concluded that hair pigmentation, as measured by eumelanin-to-pheomelanin ratio, is not a risk factor for developing alopecia areata when compared to androgenetic alopecia patients.

This review discusses the use of phosphodiesterase inhibitors for alopecia, finding promising preliminary results with topical caffeine for androgenetic alopecia and telogen effluvium, but limited success in alopecia areata.

Low-dose pulsed electric fields in a rat model shifted hair follicles from resting to active growth, with voltage as the most influential factor.

This review reports that botulinum toxin is used in dermatology not only for treating rhytides but also for conditions like rosacea, hyperhidrosis, and menopause-related flushing, although its full safety and efficacy profile requires more research.

This review found that insulin-chitosan formulations, such as gels and dressings, show promise in wound healing through anti-inflammatory and antimicrobial effects, although most evidence is from preclinical studies and further research is needed to understand mechanisms.

This review examined the diverse therapeutic potentials of cannabinoids, highlighting their applications in pain, neurological, and cancer treatments, and emphasized the benefits of biodegradable polymers in improving drug delivery; however, further clinical trials are needed to fully explore these potentials.

This preclinical study found that exercise-induced extracellular vesicles delayed breast cancer tumor growth in mice, potentially by enhancing the immune response within the tumor microenvironment.
