The authors concluded that establishing and standardizing methods for data collection are crucial to improving PCOS diagnosis and research due to challenges observed in data harmonization across diverse international cohorts.

This study found that while MSC concentration in BMCs correlates with total cell counts, cellularity does not indicate high MSC content.

In this study, researchers found that the management of alopecia areata in Poland is inadequate, despite following international guidelines, due to limited access to advanced treatments and insufficient use of severity assessments and psychosocial support.

This narrative review reports that scalp micropigmentation offers immediate cosmetic improvements in hair density appearance, but does not promote actual hair regrowth and results vary based on the operator's skill.

In this study, researchers using visual analysis reported a rising trend in platelet-rich plasma research from 2020 to 2024, with significant contributions from the United States and China, highlighting key applications in orthopedics, tissue engineering, and potential future focuses in neurogenic pain and regenerative medicine.

This clinical review evaluates current evidence on various adjunctive therapies for androgenetic alopecia, highlighting modest benefits for some interventions but emphasizing significant gaps and the need for rigorous, high-quality research to guide effective management strategies.

This review found that exposure to pollutants like PM, NOx, and PAHs is linked to various skin and hair disorders, indicating a need for cosmetics with natural adsorbents to reduce pollutant effects, achieving 30-55% removal efficiency.

This review explores the potential of platelet-rich plasma therapy for early ovarian reserve decline and premature ovarian insufficiency, indicating some ovarian function improvements in initial studies but highlighting the need for further research.

In this narrative review, researchers synthesized current evidence on topical metformin's potential benefits for various skin conditions, citing primarily preclinical studies that highlight its anti-inflammatory, antioxidant, and regenerative properties, although clinical translation requires further rigorous trials.

This review highlights the role of the brain–gut–skin axis in systemic inflammatory skin conditions, revealing potential interventions like microbiome-directed treatments and integrative therapies, though emphasizes the need for more robust clinical validation.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

Long COVID affects many survivors with ongoing symptoms, needing more research and care.

This review highlights the importance of selecting high-quality bioassays in discovering bioactive compounds from marine sources, emphasizing their role in evaluating safety and efficacy during pharmaceutical, food supplement, and cosmetic development.

In this study, researchers found that massively parallel sequencing of mitochondrial DNA (mtDNA) can improve information recovery from forensic samples, with successful full region amplification possible from as few as 2,000 mtDNA copies, albeit with variability in heteroplasmy among hair samples from the same donor.

In this study, topical and intralesional vitamin D3 and its analogs were found to be effective and safe treatments for mild-to-moderate alopecia areata, achieving a 53.75% success rate, though intralesional vitamin D3 was less effective than other treatments like corticosteroids.

This systematic review reports that there is currently no evidence supporting methotrexate for maintaining remission in ulcerative colitis; further large-scale trials are needed to assess its efficacy and safety.

This review found that alopecia areata significantly impairs quality of life, particularly through embarrassment and self-consciousness, in children and adolescents.

This review found limited evidence on the effectiveness of different antiandrogens for feminization in transgender women, suggesting cyproterone acetate, leuprolide, and medroxyprogesterone acetate may better suppress testosterone than spironolactone or estradiol alone.

This review discusses the use of platelet-rich fibrin (PRF) in musculoskeletal, oral, and maxillofacial surgeries and dermatology, but reports no new clinical results; further trials are needed.

This review outlines current European legislation and manufacturing standards for platelet-rich plasma (PRP) products and provides guidance for clinicians implementing autologous PRP treatments, without reporting new clinical results.

This study found that cortisol concentrations were significantly higher in hair samples with follicles compared to those without, suggesting potential confounding in stress assessments using different hair sampling methods.

This systematic review provides an in-depth evaluation of non-invasive imaging and biophysical methods for diagnosing and monitoring vitiligo, emphasizing the need for studies with larger sample sizes to verify their use in clinical practice and research.

This protocol outlines a nationwide study to investigate the prevalence of metabolic and reproductive abnormalities, anxiety, and depression in Brazilian women with polycystic ovary syndrome, aiming to inform public health strategies.

This review highlights that autologous platelet concentrates, particularly platelet-rich fibrin, have shown potential to enhance healing and outcomes in both dental and medical applications, including injury recovery and aesthetics.

This review suggests that MSC-derived conditioned media hold promise in dermatology, with studies indicating enhanced therapeutic effects when used alongside treatments like laser therapy and microneedling, leading to improved dermatological outcomes.

This review discusses the evolution of platelet concentrates in regenerative medicine, highlighting a proposed function-driven classification that distinguishes three generations of PCs by biological activity rather than development order, with third-generation exosome-based therapies showing superior therapeutic efficacy over earlier formulations.

This study found that non-blinded assessors in randomized clinical trials exaggerated the effects of experimental interventions by about 29% compared to blinded assessors, indicating a significant potential for observer bias in treatment evaluations.

This review reports that clinical studies generally showed favorable results for microneedling as an adjunct therapy for androgenic alopecia and alopecia areata, despite the low quality of existing data.

This review suggests that hyperspectral and terahertz imaging show promise in non-invasively assessing scalp changes associated with hair loss, but further validation is needed for clinical application.

This review assessed dermo-cosmetic treatments using prebiotics, probiotics, synbiotics, and other biotics for acne and scalp disorders, finding potential benefits, especially with multi-strain or synbiotic formulations, although challenges like formulation stability and the need for larger trials persist.
