This study found that global PCOS prevalence in adolescents is 6.3% under new 2023 guideline criteria, compared to 9.8% using Rotterdam criteria; excluding PCOM may prevent over-diagnosis, while recognizing irregular cycles or hyperandrogenism helps avoid under-diagnosis by identifying at-risk individuals for further monitoring.

This study found that hair cortisol levels increase and testosterone levels decrease with obesity, suggesting that measuring hormones in hair may be a valuable tool in obesity research and clinical practice.

The researchers reported that stress-induced keratins in human skin are expressed at lower levels than those in healthy skin and are co-regulated with genes involved in differentiation, inflammation, and immunity, rather than replacing keratins of normal differentiation or indicating cell proliferation.

This study observed that SARS-CoV-2 shedding significantly decreased after remdesivir treatment, irrespective of RT-PCR cycle threshold values, suggesting early de-isolation might be possible in severe COVID-19 cases.

In this study, researchers used a network pharmacology approach to highlight significant interactions between compounds in rosemary (Salvia rosmarinus) and genes related to functional dyspepsia, suggesting potential pathways for developing treatments against gastrointestinal diseases.

In this case study, a 78-year-old Japanese woman with Cronkhite-Canada syndrome experienced mesenteric lymphadenopathy, which reduced in size after treatment with the corticosteroid prednisolone. This suggests that mesenteric lymphadenopathy, though uncommon in CCS, may respond to steroid therapy.

This study suggests that label-retaining cells in the hair follicle contribute to follicular renewal, indicating a specific role in the hair cycle by proliferating during the late telogen phase.

This study found that human C-tactile afferents respond to hair deflection, suggesting a functionally relevant anatomical relationship to hair follicles similar to that observed in mice.

This study by Moore et al. (2025) provides the first evidence linking C-tactile afferents in humans to hair follicles, showing that these nerve fibers respond to hair movement rather than skin deformation, adding complexity to the understanding of their role in emotion and touch.

This study found that Carthamus tinctorius floret extract, at a concentration of 0.05 mg/mL, significantly inhibited 5α-reductase activity in DU-145 cells more effectively than standard treatments finasteride and dutasteride, with a stable microemulsion formulation enhancing its skin permeation and stability.

Cortisone may help hair regrow by altering the local environment, with regrowth starting 3-4 weeks after treatment, but its use is not widely recommended.

This study describes a case of cyclic thrombocytopenia where a novel MPL gene mutation may contribute to the disease, with gene expression changes in platelet and neutrophil genes preceding platelet count fluctuations.

This case report identified drug-induced lung disease caused by minoxidil in a patient initially misdiagnosed with hypersensitivity pneumonitis, stressing the need for accurate medication history.

In this case report, a 59-year-old man experienced recurrent pericardial effusion linked to minoxidil, with serologic indications of drug-induced lupus erythematosus, underscoring the need for clinicians to consider this rare complication of widespread minoxidil use.

This study observed that topical oligonucleotide penetration in mouse skin involves a follicular route, suggesting potential suitability for targeting hair follicle-related structures.

This review discusses the potential role of nutraceuticals in preventing and treating COVID-19 and post-COVID syndrome, but reports no new clinical findings; the authors highlight the need for further research.

An 81-year-old woman's severe male hormone symptoms were caused by an ovarian tumor, which was treated with surgery.

This study found that the MTHFR gene C677T mutation appears to be a susceptibility factor for alopecia areata in the Turkish population.

This review discusses the potential uses of inorganic nanomaterials for imaging and detecting brain diseases, but reports no new experimental results; it calls for improvements in diagnosis precision and imaging accuracy.

This study found that certain lncRNA gene polymorphisms in HOTAIR and MALAT1 are associated with increased susceptibility to systemic lupus erythematosus, potentially informing clinical applications.

This case report describes three instances where occult ovarian Leydig cell tumors were suspected based on severe hyperandrogenism symptoms, despite negative imaging findings, highlighting that elevated testosterone levels are a crucial diagnostic marker.

This case report observed that delirium can be the sole symptom of a stroke, as seen in an elderly patient with a thalamic hemorrhage, highlighting the need to consider stroke in the differential diagnosis when delirium is present without focal neurological signs.

Doctors used a special blood sampling technique to diagnose a woman's rare ovarian tumor that was producing male hormones.

This study found that chitosan nanoparticles containing Cordyceps militaris effectively reduced lung damage in mice exposed to fine particulate matter (PM2.5) by decreasing oxidative stress and preserving lung barrier integrity, suggesting potential as a therapeutic candidate for PM2.5-induced lung diseases.

In this study, researchers identified two genetic mutations associated with producing finer and denser wool in fine-wool sheep, involving the genes KRT74 and EDAR, which may guide future breeding efforts to enhance wool quality.

This study reported that Lung-Ultrasound effectively monitors lung recovery in COVID-19 ARDS survivors, and identified a link between high EPAP-CPAP pressure and cardiopulmonary impairment.

This study found that the human hairline is closely linked to several cranial, cerebral, and vascular structures, enabling precise localization of key neuroanatomical landmarks, which could assist in planning neurosurgical procedures.

This case study highlights the challenges of diagnosing hyperandrogenism in postmenopausal women, reporting a patient with androgenic alopecia and high testosterone due to a benign Leydig cell tumor in the ovary; surgery successfully normalized testosterone levels.

This case report details a 28-year-old male who developed trichotillomania following a traumatic brain injury, highlighting diagnostic challenges in distinguishing overlapping psychiatric and compulsive behaviors, and underscores the importance of a comprehensive, multidisciplinary treatment approach.

This case report highlights the importance of considering SLE in young male patients with unexplained inflammatory musculoskeletal symptoms, as systemic inflammation was identified and symptoms improved with hydroxychloroquine.
