This review discusses the nutritional and metabolic problems following bariatric surgery, emphasizing the need for ongoing monitoring and treatment, but reports no new clinical results.

This study found that desmocollin 1 is crucial for strong adhesion and barrier maintenance in the mouse epidermis, with its absence leading to skin and hair issues resembling chronic dermatitis.

This study observed that baricitinib treatment led to significant improvement in a patient's alopecia areata symptoms and suggests further clinical trials to explore its potential as a treatment.

In two phase 3 trials, this study found that oral baricitinib significantly improved hair regrowth compared to placebo in adults with severe alopecia areata after 36 weeks, though longer trials are needed to ascertain its long-term efficacy and safety.

This review examines nutritional deficiencies after bariatric surgery, particularly in essential minerals like zinc and copper, and highlights the need for more research to improve post-surgery nutritional outcomes.

This study found that epidermal VEGF is crucial for maintaining skin barrier function in mice and may help explain psoriasis development following skin trauma due to its effects on angiogenesis and hyperplasia.

In this study, targeted deletion of the stearoyl-CoA desaturase 1 gene in mice disrupted the epidermal lipid barrier, leading to increased water loss, impaired thermoregulation, and metabolic issues.

This study found that bariatric surgery effectively treated morbid obesity and improved quality of life and the resolution of comorbidities for most patients.

In this phase 2 study, baricitinib at 2 mg and 4 mg doses significantly improved hair regrowth in adults with alopecia areata and ≥50% scalp hair loss compared to placebo, without new safety concerns, although the small sample size limits the results' generalizability.

This study reported that inhibiting the JAK-STAT pathway with baricitinib restored cellular homeostasis, delayed senescence, and reduced proinflammatory markers in Hutchinson-Gilford progeria syndrome cell models.

This review discusses baricitinib's applications for various inflammatory disorders and highlights its promising efficacy alongside potential adverse effects, advocating for further research before it becomes a standard treatment.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This study found that procyanidin B-3, a compound isolated from barley extract, may promote hair growth by enhancing hair epithelial cell growth and counteracting TGF-β1's growth-inhibiting effects in vitro and in vivo.

Treat scalp and beard fungal infections early with oral antifungal medication and sometimes topical therapy, avoiding unnecessary allergy tests and surgery.

This study found that porcine ear skin is more suitable than excised human skin for investigating the efficacy of barrier emulsions in preventing pollen allergen penetration due to its lack of tissue contraction.

In this study, the authors concluded that arabinogalactan proteins recognized by specific antibodies are involved in the differentiation and development of barley root epidermal cells, contributing to root hair development.

This review summarizes the effects and complications of bariatric surgery on skin, noting it can alter existing skin conditions like psoriasis and trigger new dermatoses, but provides no new clinical results.

In this study, loss of epidermal Par3 in mice disrupted the skin barrier and affected cell differentiation and stem cell maintenance, highlighting its role in epidermal homeostasis.

This article discusses the role of interleukin-15 and Janus kinase inhibitors in alopecia areata based on a murine model and reports no new experimental results.

In this analysis, safety data from two clinical trials showed that baricitinib for severe alopecia areata had predictable side effects like infections and elevated CPK, with some serious adverse events noted at low incidence rates; no deaths were reported.

Adequate zinc and iron intake may reduce hair loss after bariatric surgery.

The abstract provides a brief mention of alopecia areata (AA) being a chronic immune-mediated disorder causing non-scarring hair loss, but specific study results or findings relating to this are not reported.

In this study, researchers found that barrier-enhancing formulations significantly reduced the penetration of proteins into hair follicles in porcine skin models, with effectiveness varying by formulation.

In this study, 40.9% of patients taking 4 mg baricitinib and 21.2% taking 2 mg achieved significant hair regrowth over 52 weeks, indicating potential long-term benefits for adults with severe alopecia areata without introducing new safety concerns.

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

This study found that hair loss is common following metabolic and bariatric surgery, particularly among younger women with low serum levels of zinc, folic acid, and ferritin.

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 study suggests that off-label use of baricitinib in children under 12 with alopecia areata may improve hair regrowth, but further research is needed to confirm efficacy and safety.

This Italian study observed that one third of patients with 25 to 50% scalp hair loss from alopecia areata still experienced active patchy disease at long-term follow-up, and another third progressed to more severe forms like alopecia totalis or universalis, with limited recovery.

This study found that hydrophobic lipid-coated silica nanoparticles penetrated deeper into human stratum corneum compared to their hydrophilic counterparts, highlighting the influence of surface polarity on skin penetration.
