This publication discusses the 2021 ESC Guidelines for the prevention of cardiovascular disease in clinical practice and reports no new results.

This article suggests that modern lifestyle changes, including diet, stress, and chronic anti-inflammatory medication use, may disrupt the natural process of inflammation resolution, increasing vulnerability to chronic disease.

This study found that lifestyle interventions improved body composition, hyperandrogenism, and insulin resistance in women with PCOS, but did not affect glucose tolerance, lipid profiles, or clinical reproductive outcomes.

This review discusses the potential impact of lifestyle factors on the progression of androgenetic alopecia and reports no new clinical findings; the authors emphasize the need for more comprehensive studies.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This perspective suggests that browning agents may not directly enhance UCP1 expression in white adipose tissue but instead induce browning through increased heat loss, prompting thermogenesis to compensate.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This review discusses segmental vitiligo as part of the vitiligo clinical spectrum and highlights its role as a model for studying repigmentation, but reports no new clinical results.

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This book discusses current research on polycystic ovary syndrome, including diagnosis, management, and the impact of lifestyle changes, without reporting new clinical results.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

This review discusses polycystic ovary syndrome, its detection, and treatments, concluding that lifestyle changes may offer sustainable management, although it reports no new clinical results.

This study observed that in young women, the scalp microbiota is influenced by sebum level, barrier sensitivity, and lifestyle factors, with barrier sensitivity emerging as a key factor, offering insights for further research into scalp health and conditions.

Women with PCOS often have insulin resistance, abnormal lipid levels, and a higher risk of diabetes and heart disease; lifestyle changes and medication like metformin can help manage these risks.

This article reviews the underlying mechanisms of segmental vitiligo with white hair, focusing on skin and hair follicle melanocytes, and proposes potential targets for treatment, highlighting neuroendocrine factors as possible contributors to the condition.

This review discusses the association between emotional stress-related neuropeptides and the pathogenesis of alopecia areata, reporting no new experimental findings.

Mesotherapy is a minimally invasive treatment with potential benefits and risks, requiring standardized practices and further investigation.

This review discusses various theories of skin aging and the importance of using professional and at-home skincare solutions, but offers no new empirical findings.

This narrative review highlights that endurance, skill-oriented athletes, and physique-oriented competitors such as bodybuilders face accelerated degradation of fillers and botulinum neurotoxin due to elevated basal metabolic rates and other factors, and raised concerns about psychological conditions like body dysmorphic disorder in these populations.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This review explores the complex biological process of hair graying, highlighting oxidative stress, genetic factors, and interventions like antioxidants and genetic therapy as key aspects affecting the preservation of hair pigmentation.

This review discusses the association between various skin conditions and metabolic syndrome, reporting no new clinical results but suggesting a potential reciprocal relationship that warrants further investigation.
