Expanding the Psoriasis Framework: Immunopathogenesis and Treatment Updates.

Psoriasis is a chronic heterogeneous condition with multiple available treatment options that have resulted in dramatic disease improvements for patients. IL-23/IL-17 signaling is the central immune signaling pathway driving psoriasis, though recent research has uncovered other key contributing signals such as IL-17C, IL-17F, IL-36, and tyrosine kinase 2 (TYK2). Novel therapeutic targets inhibiting these cytokines have expanded our understanding of the pathogenesis of psoriasis. IL-23/IL-17 signaling is critical for the development of epidermal hyperplasia and the mature psoriatic plaque in susceptible individuals. Increased IL-17 and IL-23 expression works synergistically with other cytokines, such as IL-12, IL-22, IL-36, tumor necrosis factor (TNF), and interferon (IFN), to help create a self-sustaining, feed-forward circuit in keratinocytes, which contributes to the chronicity of the disease. This clinical review highlights recent discoveries in the immunopathogenesis of psoriasis and summarizes new antipsoriasis therapies targeting IL-36, IL-17F, aryl hydrocarbon receptors (AHRs), phosphodiesterase 4 (PDE4), and TYK2 signaling. Despite recent success in the treatment of psoriasis, continued research is needed to further advance disease understanding and shape management strategies.

Virtual Learning Decreases the Carbon Footprint of Medical Education.

INTRODUCTION: The environmental impact of holding in-person academic conferences and continuing medical education (CME) programs can be significant. In-person conferences provide a unique social and professional platform to engage in networking and foster professional development; however, there is an opportunity for hybrid and virtual platforms to provide CME for broader audiences looking to improve their clinical skills and strengthen their knowledge base. This study seeks to describe the reduction in carbon emissions associated with a webinar hosted by an online dermatology-focused medical education platform. METHODS: This cross-sectional study used the location of deidentified virtual attendees of a webinar to predict the carbon emissions produced if attendees had instead traveled to the location of the most recent Integrative Dermatology Symposium (Sacramento, CA). Following collection of each virtual attendee's location, the mode of transportation was predicted on the basis of each participant's distance to the conference. RESULTS: The estimated carbon emissions were calculated for 576 participants. The total estimated, unadjusted carbon emissions for both attendees predicted to fly or drive was 370,100 kg CO2. The emissions produced per participant from those expected to fly to an in-person CME after adjusting for all additional passengers on every flight were 4.5 kg CO2. The emissions produced per participant from those expected to drive were 42.7 kg CO2. CONCLUSION: The use of a virtual CME webinar led to a significant reduction in travel-related carbon dioxide emissions when compared to running the same program in-person event. When accounting for all passengers traveling via plane on any flight, driving to an event produced more emissions per participant than flying.

The Gut and Skin Microbiome in Alopecia: Associations and Interventions.

Objective: This review examines the current literature on the gut-skin connection in alopecia and summarizes interventions that impact hair growth by modulation of the gut or skin microbiome. Methods: PubMed searches were done to assess studies of the gut and skin microbiome and forms of alopecia including, alopecia areata (AA), androgenic alopecia (AGA), alopecia universalis (AU), central centrifugal cicatricial alopecia (CCCA) and lichen planopilaris (LPP). Filters were applied for human and animal studies. Articles not translated to English and studies assessing supplemental therapies on alopecia were excluded. Results: There is evidence that scalp, hair follicle, and gut microbiome alterations are associated with various types of alopecia. There is potential in the use of interventions targeting microbiome dysbiosis, including fecal transplants and probiotics. Limitations: This field of study still requires more high-quality research and studies with larger participant populations. Conclusion: Dysbiosis on the scalp, within the hair follicle and the gut seem to have a role in the pathophysiology of various forms of alopecia. There is evidence that interventions targeting dysbiosis may have potential in the treatment and management of hair loss. Further studies are needed to establish a direct connection and to clarify specific effects of these interventions.

Correlating the Gut Microbiota and Circulating Hormones with Acne Lesion Counts and Skin Biophysical Features.

Acne vulgaris is a common inflammatory condition that is multi-factorial and impacted by both intrinsic and extrinsic features. Several previous studies have assessed for correlations between factors such as circulating hormones, stress, or the microbiome. However, there have not been any correlations specifically against lesion counts or differentiating correlations between inflammatory and non-inflammatory lesion counts. Here, we correlate several factors against acne lesions. Twenty men and women with mild to moderate acne were recruited, and their hormonal levels and their gut microbiome were collected and correlated against their inflammatory and non-inflammatory lesions of acne. Facial non-inflammatory lesions were weakly correlated to sebum excretion rate and weakly inversely correlated to forehead and cheek hydration. We examined stress through the use of a normalized peak-to-trough ratio (higher numbers indicated less stress), which correlated with skin hydration and inversely correlated with sebum excretion rate. Sebum excretion rate was weakly correlated to testosterone levels, and facial hydration correlated with estradiol levels. Correlations with the gut microbiome showed differential correlations with inflammatory and non-inflammatory lesions, with Clostridium sp AF 23-8 correlating to inflammatory lesion counts, while Actinomyces naeslundii str Howell 279 correlated to non-inflammatory lesions. Overall, measures of stress and circulating hormones correlate to skin biophysical properties and acne lesion counts. Also, different gut bacteria correlate with either inflammatory or non-inflammatory lesion counts. We hope that our findings stimulate further work on the gut-mind-stress-skin axis within acne.

A review of the use of beeswax in skincare.

BACKGROUND: Beeswax is a naturally occurring product secreted from worker bees that has varied uses in modern day. In skincare, its function ranges from its role as an occlusive, helping to create a semi-occlusive skin barrier that minimizes transepidermal water loss; as a humectant, locking in hydration; and an emollient to soften and soothe the skin. As a natural substance, its use has been shown to help alleviate symptoms associated with common cutaneous conditions like dermatitis, psoriasis, and overgrowth of normal skin flora. AIMS: In this narrative review, we aim to describe current uses of beeswax in skincare that has been published in the literature. MATERIALS AND METHODS: A review of beeswax related publications was performed by searching the PubMed database studies. RESULTS: A total of five clinical studies were included with three studies on animals and two studies in humans. DISCUSSION: Several studies show the benefits of topical beeswax in supporting the skin barrier. CONCLUSION: Beeswax can be a low-cost, natural ingredient for use in products. Further studies with topical beeswax are warranted.

Systematic Review of Psychological Interventions for Quality of Life, Mental Health, and Hair Growth in Alopecia Areata and Scarring Alopecia.

Alopecia is associated with significant psychological burden. There is limited evidence on the use of psychological interventions in conditions of hair loss. This manuscript systematically reviews the current state of literature on psychological treatments for quality of life, mental health, and hair growth in various forms of alopecia. PubMed and Embase were searched with predefined inclusion and exclusion criteria. Reference lists were also examined for relevant studies. Nine articles met our criteria and are included in this review. Eight of the articles related to alopecia areata and one related to scarring alopecia. Mindfulness-based stress reduction (MBSR) was found to improve quality of life-related subjective symptoms, relationship impacts, anxiety, phobia, distress, and psychological symptom intensity. Alopecia-specific collocated behavioral health (CLBH) treatment showed a trend for psychosocial improvement in areas such as appearance shame, activity avoidance, negative emotions, and coping. Hypnotherapy was found to improve anxiety and depression, quality of life measures, and alexithymia. There was also some evidence for significant hair growth with hypnosis, but the data are mixed. Psychotherapy combined with immunotherapy led to more hair growth, and supported self-confidence. Finally, coping strategies modulated the subjective burden of alopecia, and were associated with disease improvement. Further research will be necessary to better establish the efficacy and optimal administration of these interventions in alopecia.

Prospective Evaluation of a Topical Botanical Skin Care Regimen on Mild to Moderate Facial and Truncal Acne and Mood.

Acne vulgaris is a common inflammatory condition that can be associated with profound psychosocial impacts. Conventional treatment includes topical retinoids, benzoyl peroxide, and antimicrobials, and some may cause irritation and skin dryness. In this 8-week open-label study, we examined the effects of a botanical skin care regimen (Codex Labs Shaant Balancing regimen) on mild to moderate facial and truncal acne. Twenty-four male and female subjects between the ages of 12 and 45 years were assessed for eligibility, 20 were enrolled, and 15 completed all study visits. Facial and truncal acne lesion counts, skin hydration, sebum excretion rate, and mood were assessed at baseline, week 4, and week 8. Total facial lesion counts (inflammatory and non-inflammatory lesions) decreased by 20.5% at week 4 (p = 0.06) and by 25.2% at week 8 (p < 0.05). Inflammatory lesion counts on the trunk were found to decrease at week 8 relative to baseline by 48% (p < 0.05). Forehead sebum excretion rate decreased by 40% at week 4 (p = 0.07) and 22% at week 8 (p = 0.08), and cheek skin hydration increased by 27.6% at week 4 (p = 0.14) and 65% at week 8 (p = 0.10). Participants also experienced significant improvement in components of a positive effect, such as feeling "strong" and "inspired", and a decrease in negative effects, such as feeling "irritable." Overall, the botanical skin care regimen was found to be well-tolerated. Our study suggests that a botanical skin care regimen may reduce facial and truncal acne lesion counts, increase skin hydration, reduce sebum production, and augment positive effects and moods in those with mild to moderate facial and truncal acne.

Parental and Provider Perceptions of Sugar-Sweetened Beverage Interventions in the First 1000 Days: A Qualitative Study.

BACKGROUND: Novel approaches to reduce sugar-sweetened beverage (SSB) consumption during the first 1000 days-pregnancy through age 2 years-are urgently needed. OBJECTIVE: To examine perceptions of SSB consumption and acceptability of potential intervention strategies to promote SSB avoidance in low-income families in the first 1000 days. METHODS: In this qualitative research, we performed semistructured, in-depth interviews of 25 women and 7 nutrition/health care providers. Eligible women were Women, Infants, and Children program-enrolled and pregnant or had an infant younger than age 2 years. Eligible providers cared for families during the first 1000 days. Using immersion-crystallization techniques, we examined perceptions, barriers, and facilitators related to avoidance of SSB consumption; acceptability of messages framed as positive gains or negative losses; and perceived influence on SSB consumption of various intervention modalities. RESULTS: Themes related to SSB consumption included parental confusion about healthy beverage recommendations and maternal feelings of lack of control over beverage choices due to pregnancy cravings and infant tastes. Themes surrounding message frames included negative health consequences of sugary drink consumption are strong motivators for behavior change; and savings and cost count, but are not top priority. Highly acceptable intervention strategies included use of images showing health consequences of SSB consumption, illustrations of sugar content at the point of purchase, and multimodal delivery of messages. CONCLUSIONS: Messages focused on infant health consequences and parental empowerment to evaluate and select healthier beverages based on sugar content should be tested in interventions to reduce SSB consumption in the first 1000 days.

Isotope-reinforced polyunsaturated fatty acids protect mitochondria from oxidative stress.

Polyunsaturated fatty acid (PUFA) peroxidation is initiated by hydrogen atom abstraction at bis-allylic sites and sets in motion a chain reaction that generates multiple toxic products associated with numerous disorders. Replacement of bis-allylic hydrogens of PUFAs with deuterium atoms (D-PUFAs), termed site-specific isotope reinforcement, inhibits PUFA peroxidation and confers cell protection against oxidative stress. We demonstrate that structurally diverse deuterated PUFAs similarly protect against oxidative stress-induced injury in both yeast and mammalian (myoblast H9C2) cells. Cell protection occurs specifically at the lipid peroxidation step, as the formation of isoprostanes, immediate products of lipid peroxidation, is drastically suppressed by D-PUFAs. Mitochondrial bioenergetics function is a likely downstream target of oxidative stress and a subject of protection by D-PUFAs. Pretreatment of cells with D-PUFAs is shown to prevent inhibition of maximal uncoupler-stimulated respiration as well as increased mitochondrial uncoupling, in response to oxidative stress induced by agents with diverse mechanisms of action, including t-butylhydroperoxide, ethacrynic acid, or ferrous iron. Analysis of structure-activity relationships of PUFAs harboring deuterium at distinct sites suggests that there may be a mechanism supplementary to the kinetic isotope effect of deuterium abstraction off the bis-allylic sites that accounts for the protection rendered by deuteration of PUFAs. Paradoxically, PUFAs with partially deuterated bis-allylic positions that retain vulnerable hydrogen atoms (e.g., monodeuterated 11-D1-Lin) protect in a manner similar to that of PUFAs with completely deuterated bis-allylic positions (e.g., 11,11-D2-Lin). Moreover, inclusion of just a fraction of deuterated PUFAs (20-50%) in the total pool of PUFAs preserves mitochondrial respiratory function and confers cell protection. The results indicate that the therapeutic potential of D-PUFAs may derive from the preservation of mitochondrial function.
