In this study involving patients with Multiple Sclerosis, higher hair cortisol levels and being Black were linked to poorer cognitive performance, while increased perceived stress and depression were associated with greater fatigue, highlighting distinct associations between objective and subjective stress measures and MS-related outcomes.

This study found that women with PCOS had significant hormonal imbalances, increased central obesity, and a lower 2D:4D digit ratio, suggesting prenatal androgen exposure may play a role in the condition's development.

This study found no significant difference in 2D:4D ratios and autism questionnaire scores between acne vulgaris patients and healthy controls, despite investigating potential links in this novel context.

This case report aims to raise physician awareness about 'toe-tourniquet' syndrome, which can lead to digit loss if not promptly treated, and to prevent its misdiagnosis as child abuse.

This essay discusses the role of the nail in mammalian digit tip regeneration and explores whether nail stem cells are solely responsible for this regenerative ability, with no new results presented.

This study found that males with androgenetic alopecia had a significantly lower 2D:4D digit length ratio in the right hand compared to healthy controls, which may indicate prenatal androgen exposure.

In this study, researchers found that mouse digits without nails could not regenerate after amputation, highlighting the necessity of nails for fingertip regeneration and suggesting a potential role for the Lmx1b gene in this process.

In this article, two case studies of hair tourniquets around digits are discussed, highlighting the condition's potential causes and management strategies, and emphasizing the role of midwives and health visitors in educating expectant mothers to minimize the risk to children.

In this study, researchers found that the glabrous skin of the rat forelimb contains sparse Meissner corpuscles and Merkel complexes, with more slowly adapting afferents in the palm and rapidly adapting afferents in the digit extremity.

This case report describes a father with HOXC13-associated pure hair-nail ectodermal dysplasia, presenting with severe nail dystrophy affecting all digits and notable hypotrichosis or complete alopecia.

Finger length ratios are not linked to the number of specific gene repeats affecting testosterone sensitivity.

This article discusses Hair-thread Tourniquet Syndrome in children, emphasizing the need for prompt examination and intervention to prevent severe complications, but reports no new clinical results.

This article reviews the issue of hair-thread tourniquets in infants, emphasizing the importance of awareness for timely diagnosis and suggesting prevention strategies, but reports no new clinical results.

In this study, among over one million COVID-19 patients, several long-term effects were identified, with age and gender commonly associated, while other social determinants showed limited significant associations.

This case report describes a 45-year-old woman with an SLE-SSc overlap syndrome who experienced significant improvement in symptoms after tailored immunosuppressive therapy including prednisone and mycophenolate mofetil.

This study found that numerous long-term effects of SARS-CoV-2 were significantly associated with age and gender, while race, income, and education had limited significance.

This study demonstrated that acute thallium poisoning primarily manifests with gastrointestinal issues, polyneuropathy, and dermatological changes, and treatments like hemoperfusion and hemodialysis may improve symptoms.

This study used confocal Brillouin microscopy to observe that a decrease in tissue compressibility occurs during the development and regeneration of axolotl limbs, suggesting mechanical changes linked to regeneration stages undetectable by fluorescence microscopy.

This report describes a case of scarring alopecia in a 7-year-old girl, highlighting the presence of inflammation without true sclerosis despite normal bone age and negative fungal tests.

This review examines the roles of macrophages and fibroblastic cells in organ injury and repair, discussing their impact on outcomes ranging from regeneration to fibrosis, without presenting new clinical results.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

In this pilot study, no significant differences were observed between memantine and placebo groups in young adults with Down syndrome on the primary memory outcomes, but some improvement was noted in a secondary measure.

This case report suggests that frontal fibrosing alopecia with nail involvement may be associated with lichen planus and improved with oral dutasteride due to an inflammatory reaction related to androgenetic alopecia.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

This study reports various methods used by hair transplant surgeons to count and manage follicular grafts during follicular unit extraction hair restoration, including manual counting and the use of automated or digitalized graft counters.

Finasteride effectively treated hidradenitis suppurativa.

This report describes a rare case of hair and nail ectodermal dysplasia in a 3-year-old girl, where treatment with topical minoxidil resulted in minimal improvement after 12 months.

This review discusses recent advances in understanding the cellular, molecular, and genetic factors contributing to lupus erythematosus and reports no new experimental findings.

This study found that dutasteride was more effective than finasteride in increasing total and thick hair count and reducing thin hair count in men with AGA, with both drugs having similar side effect profiles.

In this case report, a woman in her 50s was diagnosed with meningitis linked to mixed connective tissue disease after presenting symptoms similar to infectious meningitis, but with no infection detected and serological evidence pointing to the autoimmune condition.
