In this study, two patients with long-term total parenteral nutrition and no biotin intake experienced hair regrowth after biotin supplementation, suggesting biotin deficiency can lead to alopecia.

Healthcare professionals need better training and systems for drug interaction reporting, injectable vitamin B12 helps tingling, oral helps numbness, probiotics may help ulcerative colitis, and more research is needed on Post-Finasteride Syndrome.

This study found that human liver dehydroepiandrosterone sulfotransferase (DHEA ST) catalyzes the sulfate conjugation of minoxidil, indicating another pathway contributing to its metabolism in humans.

This study found that finasteride treatment in male rats led to enduring effects on depressive-like behavior, hippocampal neurogenesis and neuroinflammation, and gut microbiota composition after withdrawal.

This study introduces MicrobeFDT, a tool that clusters chemically similar compounds and links them to gut microbial enzymes and toxicities, demonstrating its utility by uncovering previously unknown metabolism of the cancer drug altretamine.

This study found that the gut microbiota composition in patients with post-finasteride syndrome differs significantly from healthy controls, with reduced diversity and specific microbial changes, suggesting a potential diagnostic marker and therapeutic target.

In this study, researchers observed that DHEA-induced PCOS rats experienced significant changes in gut microbiota and metabolic profiles, particularly affecting steroid and lipid metabolism, suggesting the gut-ovary axis may play a role in the pathogenesis of PCOS.

This review examines the potential role of gut microbiota and its metabolites in polycystic ovary syndrome (PCOS) and highlights the growing interest in this area; it reports no new clinical findings.

In this report, successful management of inherited acrodermatitis enteropathica, a zinc absorption disorder due to an SLC39A4 gene defect, was demonstrated in an infant through zinc supplementation.

In this study, researchers found that intestine-derived human alpha defensin 5 enhances wound healing, reduces bacterial load, and promotes hair growth in murine burn wound beds by increasing LGR stem cell migration.

This study suggests that cedrol may improve mitochondrial function, gut microbiota, and intestinal barrier integrity, indicating its potential value in treating inflammatory bowel disease.

This study suggests that bioactives like Curcumin, Quercetin, and "Tulsi" may relieve chemotherapy-induced adverse drug reactions in cancer patients, potentially reducing resistance and recurrence.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

The study found that enhancing quercetin bioavailability with EubioQuercetin may amplify its anti-aging effects in mice by modulating the gut microbiota and improving intestinal barrier function.

This study observed that M. domestica larva-derived chitosan and gut extracts enhanced wound healing and collagen deposition in both immunocompetent and immunosuppressed mice, indicating potential benefits for combined therapy.

This study found that enhancing quercetin bioavailability with EubioQuercetin significantly improved external aging signs in mice and influenced gut microbiota and intestinal gene expression, suggesting potential modulation through the gut microbiota–intestinal barrier axis.

This review discusses the range of long-term complications, including mucocutaneous, ocular, and psychological sequelae, for survivors of Stevens–Johnson syndrome and toxic epidermal necrolysis, but reports no new clinical results.

This report details a case of severe protein-energy malnutrition resembling kwashiorkor in a 43-year-old woman after bariatric surgery, highlighting the crucial role of early diagnosis and a multidisciplinary approach in managing nutritional complications and improving outcomes in similar patients.

This review discusses the mechanisms underlying immune tolerance failure in alopecia areata and highlights potential therapeutic avenues for restoring hair growth and achieving sustained remission, but reports no new clinical results.

This study found that hair follicles from dogs with recurrent flank alopecia regenerated and regrew hair when grafted onto mice, suggesting systemic rather than local factors may drive the condition.

This study found that antibiotic-induced gut dysbiosis, particularly overgrowth of Lactobacillus murinus, can lead to hair loss in mice by depleting biotin.

This study found that administering the gut bacterium Thauera sp. strain GDN1 to mice significantly reduced their serum androgen levels, indicating gut bacteria may influence androgen metabolism.

This study concluded that Aloe vera fermentation significantly accelerates burn injury healing in rats by reducing inflammation and altering gut microbiota composition.

This study found that patients with alopecia areata had a significantly different gut microbiota composition compared to healthy controls, suggesting possible microbiota involvement in the disease's pathogenesis.

This review discusses the potential link between gut microbiota alterations and the onset and progression of alopecia areata, identifying it as a possible pathogenetic factor and therapeutic target, but reports no new clinical results.

This preclinical study found that finasteride withdrawal in rats caused inflammation in the gut and hypothalamus, while allopregnanolone treatment partially reduced these effects, suggesting potential therapeutic benefits for post-finasteride syndrome.

This study observed that pancreatic cancer-related skin lesions in mice are linked to microbiota imbalances, specifically noting changes in the abundance of certain bacterial genera, which may offer potential diagnostic or therapeutic targets for managing skin complications in humans with pancreatic cancer.

This study identified specific gut bacterial pathways that may serve as potential therapeutic targets for managing androgenetic alopecia in obese individuals.

This study found that oral administration of solubilized sturgeon oil in mice promoted hair growth and positively influenced the gut microbiome associated with hair growth promotion.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.
