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 shares preliminary findings that roxithromycin treatment tendentially increased hair shaft production and altered the hair follicle microbiota in human hair ex vivo, with substantial inter-individual differences observed.

In this study, lifelong barley intake in SAMP8 mice was associated with extended lifespan, improved aging-related phenotypes, and beneficial shifts in the intestinal microbiome.

This review explores the potential roles of the gut and skin microbiome in alopecia areata, suggesting topical and systemic strategies for managing the condition, but it reports no new clinical results.

In this study, patients with scalp seborrheic dermatitis exhibited distinct patterns of allergen sensitization tied to symptoms, impaired skin barrier, and altered microbiota, emphasizing the need to consider allergen exposure, barrier status, and microbial balance when interpreting patch test results.

This review discusses the relationship between gut microbiota and polycystic ovarian syndrome (PCOS), including its potential mechanisms and the role of alterations in microbiome composition on PCOS pathophysiology.

This article discusses a novel hypothesis on the role of hair follicles in dandruff pathogenesis, focusing on immune response and inflammation due to scalp microbiota changes and sebum by-products, but reports no new clinical results.

This research indicates that androgens may drive hidradenitis suppurativa in some patients, as they show higher testosterone levels compared to nonaffected controls, and testosterone-lowering medications are established treatments for milder cases.

This review details skin conditions in children and adolescents related to the SARS-CoV-2 pandemic, emphasizing mask-related acne and various cutaneous manifestations linked to infection and vaccination, with most being mild or nonspecific.

Addressing biological changes in lipids, metabolism, and microbiota may help treat hair loss in young Chinese females with oily scalps.

This review explores the complex causes and treatment options for alopecia, emphasizing that current therapies mainly offer symptomatic relief, while new advancements like stem cell approaches and improved drug delivery systems show promise for addressing underlying disease mechanisms.

This review highlights that alopecia's complex causes include hormonal, genetic, and environmental factors, and discusses traditional and emerging therapies, suggesting a need for multi-targeted, mechanism-based treatments to improve long-term management and efficacy.

This review discusses the link between PCOS and acne, highlighting the roles of hyperandrogenism and insulin resistance, but it reports no new clinical findings.

This review discusses how urban air pollutants may influence the regulation of JAK3 signaling in alopecia areata and reports no new experimental results; the authors integrate existing data to map potential pathways and biomarkers.

This review discusses the complex mechanisms behind acne vulgaris and suggests that dietary modification, along with pro- and prebiotics, may influence its pathogenesis by addressing stress-induced skin inflammation.

Changes in scalp bacteria are linked to female hair loss, suggesting new treatment options.

This review discusses the relationship between skin microbiome changes and conditions such as ageing and skin disease, emphasizing the need for further research, but reports no new findings.

This study found that bacterially induced metabolic changes in stem cells can enhance skin and hair follicle regeneration in both mice and humans, suggesting potential strategies for improving recovery after injury.

This study analyzed changes in the microbiota during antler velvet regeneration in sika deer and found significant differences in microbial community composition between 15 and 30 days post-pedicle casting, highlighting the potential roles of specific bacteria in wound healing and tissue regeneration.

This study found that a nutritional intervention in dogs led to changes in skin microbiome and immune-related gene expression, with reduced levels of certain fungal pathogens and a potential alleviation of atopic dermatitis symptoms.

This study identified that bacterially-induced metabolic changes in keratinocytes enhance skin and hair follicle regeneration, suggesting that modifying skin microbiome interactions may improve wound healing.

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

This study found that patients with scalp seborrheic dermatitis exhibited distinct allergy sensitization patterns linked to skin barrier dysfunction and changes in scalp microbiota, suggesting the importance of context in interpreting patch test reactivity.

In this study, researchers observed that individuals with alopecia areata exhibited significant changes in scalp microbiota diversity and composition, which were linked to disease severity and inflammation markers, though it remains unclear if these microbial shifts are a cause or a result of hair loss.

This study developed a rapid ATP assay that effectively measures microbial populations on the skin and tracks changes after microbiome dysbiosis, with findings suggesting that ethanol-cleansed skin takes longer to recover than tape-stripped skin.

This study found that piglets' rapid growth during nursery and lactation was linked to changes in microbiota composition and increased cortisol conversion, highlighting critical early life factors influencing adult microbiota establishment.

This study found that omega-6 and saturated fatty acid-enriched diets promote weight gain and certain skin changes regardless of gut microbiota, while omega-3 diets limit adiposity and affect skin in a microbiota-dependent way in mice, highlighting a diet–microbiota–lipid relationship in skin health.

In this study, researchers highlighted that PCOS involves not only hormonal imbalances but also significant changes in the microbiome and immune system, which complicate its impact on fertility and suggest potential for new diagnostic and therapeutic strategies.

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.

This study observed that both prenatal androgen exposure and postnatal early-life environment influence the development of PCOS-like phenotypes and changes in the gut microbiota in prenatally androgenized offspring.
