Machine learning can use blood tests to help predict moderate-to-severe alopecia areata.

This study found that patients with androgenetic alopecia had significantly higher serum Osteopontin levels, which were positively associated with metabolic syndrome components, suggesting a potential role in its pathogenesis.

This study found that sebaceous-gland-derived glycerol significantly contributes to stratum corneum hydration in mice with sebaceous gland deficiencies.

This review examines the potential therapeutic effects and mechanisms of quercetin for treating polycystic ovary syndrome, noting improved clinical parameters in some studies but presenting no new results.

In this study examining male patients with androgenetic alopecia, 63.1% were found to have dyslipidemia, with more severe hair loss significantly associated with higher lipid abnormalities, suggesting a link to cardiovascular risk factors.

This study found that women with PCOS, especially those who are obese, showed higher oxidative stress and decreased antioxidant levels, correlating with metabolic syndrome and cardiovascular disease risk factors.

This study found that training in a hypoxic chamber did not significantly impact skin features in overweight and obese women, though it did result in a notable reduction in body weight and BMI.

This study found that while a nanostructured lipid carrier improved drug delivery in conventional skin models, excess sebaceous content hindered its effectiveness in targeting hair follicles.

This study found that human meibomian glands differ significantly from free and hair-associated sebaceous glands in morphology and lipid composition, making them highly specialized holocrine glands.

In this study, researchers observed that patients with androgenetic alopecia show differences in scalp microbial communities compared to the general population, including an increase in Cutibacterium acnes, particularly in males, which may interact with lipid and immune pathways to contribute to hair follicle miniaturization.

This case report associates severe zinc deficiency with long-term total parenteral nutrition, suggesting the need for trace element supplementation in such nutritional management.

This study found that a solution containing 0.5% Camellia japonica placenta extract increased scalp moisture and reduced sebum content, dead keratin, and erythema in adult females, suggesting potential as a scalp treatment.

This study found that orlistat significantly reduced weight and total testosterone levels in Iranian women with polycystic ovary syndrome after 12 weeks of treatment.

This review discusses the use of testosterone therapy for low libido in women, noting mixed evidence on breast cancer risk and a lack of long-term safety data.

This study found that patients with hidradenitis suppurativa had lower trabecular bone score and total hip bone mineral density compared to controls, with a high prevalence of vitamin D deficiency.

This study found that young women with PCOS had normal thyroid function but showed alterations in lipid metabolism, which may predispose unmarried women in this group to cardiovascular diseases.

This meta-analysis found that patients with androgenetic alopecia have an atherogenic lipid profile, with higher LDL, triglycerides, and total cholesterol, and lower HDL, potentially explaining increased cardiovascular risk.

In this study, administering 5alpha-reductase inhibitors reduced dihydrotestosterone levels and was associated with mild, reversible decreases in semen parameters in healthy men.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

The antiandrogen 11α-hydroxyprogesterone effectively reduces skin oil and cholesterol when applied to the skin.

This study found that the ethyl acetate fraction of Hibiscus rosa sinensis petals significantly reduced serum glucose and glycated hemoglobin levels in diabetic rats, with effects comparable to metformin.

In this study, researchers found that cosmetic formulations containing guaraná extract effectively controlled oiliness in oily skin and hair by reducing sebaceous gland activity and lipid content without compromising skin barrier function, making them promising for managing excessive sebum production.

This study concluded that among men with normal testosterone levels, a small increase in serum dihydrotestosterone may reduce symptoms of hypogonadism, suggesting its potential diagnostic use after ruling out hypogonadism.

Opioid use may lower PSA levels, suggesting a possible role in prostate cancer control; PSA testing is useful for detecting prostate cancer; serum triglycerides are not linked to prostate cancer risk; and higher urethral PSA levels may be associated with local hormone activity.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

This study found that osteoporosis is common among Sudanese postmenopausal women, who also showed an increased risk for cardiovascular disease, emphasizing the need for enhanced public health education and preventive measures.

This study suggests that hepatocellular carcinoma in cirrhotic men is associated with altered sex-steroid metabolism, indicated by lower testosterone and 5 alpha-dihydrotestosterone levels compared to cirrhosis alone.

This study found that both men and women with androgenic alopecia had significantly higher triglycerides, total cholesterol, and LDL-C and lower HDL-C levels than controls, suggesting increased dyslipidemia prevalence.

This study observed that the proportion of female pattern hair loss among total alopecia cases has significantly increased over the past 20-30 years, with teenage cases rising likely due to earlier puberty.

This study found that the prevalence of hyperprolactinaemia in healthy premenopausal female blood donors is low and not affected by hormonal contraceptive use, with stress-related factors being the most common cause.
