This study suggests that finasteride may help alleviate high-fat diet-induced kidney damage in mice by reducing TMAO synthesis and regulating gut microbiota.

In this systematic review, various nutrients and diets, such as a plant-based diet and supplements like omega-3 fatty acids, were found to impact tissue regeneration, skin health, and wound healing, highlighting the role of nutrient-sensitive signaling pathways in these processes.

This study found that higher dihydrotestosterone (DHT) levels in the parietal region of the scalp may be linked to androgenetic alopecia's clinical presentation.

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.

This review reports that collagen peptides consistently provide modest improvements in skin hydration and elasticity and varying benefits for body composition and cardiometabolic markers, although effects on blood sugar control are less consistent; variations in source, dose, and study definitions limit generalizability.

This review reports that collagen peptides provide consistent, modest benefits for skin hydration and elasticity, with variable effects on body composition and cardiometabolic risk markers, though some outcomes remain inconsistent due to trial heterogeneity.

This review discusses various potential risk factors and possible therapeutic interventions for polycystic ovary syndrome, including the modulation of gut microbiota, but reports no new findings.

This article provides an overview of how dermoscopy can aid in the noninvasive diagnosis of various general dermatological disorders, grouped by clinical presentation, but reports no new clinical results.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This article discusses the histologic features of psoriasis, including psoriasiform epidermal hyperplasia and neutrophilic involvement, but reports no new clinical findings.

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.

In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

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

This review discusses the roles and therapeutic effects of GLP-1 receptor agonists on the nervous, cardiovascular, and endocrine systems, but reports no new clinical results, emphasizing the need for further research on their impact on metabolism and tumor relationships in type 2 diabetes patients.

This review discusses the mechanisms behind alopecia areata and primary cicatricial alopecia and reports no new clinical results, aiming to guide the development of targeted treatments.

In this case report, an 86-year-old man experienced new hair growth and color change in alopecia areata after receiving fecal microbiota transplantation for noninfectious diarrhea.

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.

This review discusses adverse effects of 5 alpha-reductase inhibitors, particularly persistent side effects such as post-finasteride syndrome, and highlights the need for further investigation.

This study observed that fecal microbiota transplantation for ulcerative colitis may also offer incidental benefits such as weight loss, improved hair loss, and relief from axial arthritis and allergic rhinitis.

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

This study reviewed the role of probiotics in dermatological disorders and suggests they may help treat or prevent inflammatory skin conditions by modulating the microbiota, potentially reducing the need for steroids and antibiotics, though further research is needed to confirm efficacy and safety.

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.

In this study, hUCMSCs-Exo significantly accelerated wound healing in rat perianal fistulas with notable safety, potentially through the activation of the HIF-1α/TGF-β/Smad signaling pathway.

In this study, germ-free male mice showed altered levels of certain neuroactive steroids in the brain and periphery, suggesting microbiota may influence neuroendocrine pathways that support brain functioning.

This study identified a series of novel β-glucuronidase inhibitors that may help mitigate adverse effects of first-line anti-cancer drugs by targeting gut bacteria, based on virtual high-throughput screening findings.

Genetics, hormones, and microbiome changes contribute to hidradenitis suppurativa.

This article reviews skin regeneration and fibrosis, identifying key cellular and molecular players, and emphasizing the potential to manipulate the postwound environment to promote regeneration over fibrosis.

This study noted that combining oral acitretin with narrowband ultraviolet B therapy may reduce treatment time and dosages for psoriasis, potentially lowering the long-term skin cancer risk.

This study found that treatment with the synbiotic SIM01 significantly alleviated multiple symptoms of post-acute COVID-19 syndrome compared to placebo, suggesting potential management benefits through gut microbiome modulation.

This research highlighted that the gut microbiota may influence ovarian health, suggesting it could be used as a biomarker for early diagnosis and treatment of diseases like PCOS, ovarian insufficiency, and ovarian cancer due to its impact on hormone levels.
