Improving Diversity in a Novel Psoriasis Study: VISIBLE as a Framework for Clinical Trial Quality Improvement.

Importance: Diverse racial and ethnic representation in clinical trials has been limited, not representative of the US population, and the subject of pending US Food and Drug Administration guidance. Psoriasis presentation and disease burden can vary by skin pigmentation, race and ethnicity, and socioeconomic differences. Overall, there are limited primary data on clinical response, genetics, and quality of life in populations with psoriasis and skin of color (SoC).

Molecular basis of proton-sensing by G protein-coupled receptors.

Three proton-sensing G protein-coupled receptors (GPCRs), GPR4, GPR65, and GPR68, respond to changes in extracellular pH to regulate diverse physiology and are implicated in a wide range of diseases. A central challenge in determining how protons activate these receptors is identifying the set of residues that bind protons. Here, we determine structures of each receptor to understand the spatial arrangement of putative proton sensing residues in the active state.

Gene Expression Analysis of a Topical Serum Comprised of Plant-based Adaptogens Developed to Support Homeostasis and Skin Quality.

Objective: A topical serum comprised of plant-based adaptogens was purposefully developed to support the ability of the skin to adapt and achieve balance. The study described herein evaluated changes in the expression of target genes related to skin homeostasis following topical exposure.

Methods: Utilizing an epidermal skin model, quantitative polymerase chain reaction (qPCR) analysis of gene expression was conducted following 48-hour exposure to 15μL of the study product (MYS serum) to the surface of each tissue (N=4).

A Multi-center Trial Evaluating a Serum Comprised of Plant-based Adaptogens Targeting Skin Quality.

Objective: The ability of the skin to maintain homeostasis declines with age. Adaptogens support the capacity of the skin to respond to stress. We sought to evaluate the efficacy of a novel serum comprised of plant-based adaptogens for improving photoaged skin following twice-daily application.

Evaluation of an advanced antioxidant and double-conjugated retinoid/AHA cream in participants with FST IV-V.

Background: Topical antioxidants and retinoids are foundational components of an effective skincare regimen. Pyrroloquinoline quinone (PQQ) is a potent free radical scavenger that supports efficient mitochondrial energy creation. An advanced antioxidant combines topical allyl PQQ with existing WEL antioxidant technology (TAP) to comprehensively address extrinsic and intrinsic skin aging.

Treatment for central centrifugal cicatricial alopecia-Delphi consensus recommendations.

Background: There is no established standard of care for treating central centrifugal cicatricial alopecia (CCCA), and treatment approaches vary widely.

Objective: To develop consensus statements regarding the use of various pharmacological therapies in treating adults with CCCA.

Methods: We invited 27 dermatologists with expertise in hair and scalp disorders to participate in a 3-round modified Delphi study between January and March 2023.

Baseline Levels of Circulating Inflammatory Biomarkers Stratify Patients with Vitiligo Who Significantly Repigment after Treatment with Ruxolitinib Cream.

Background: Efficacy of ruxolitinib cream, a topical Jak1/Jak2 inhibitor, was demonstrated in a phase 2 trial in patients with vitiligo.

Objective: This study aimed to characterize circulating inflammatory biomarker profiles in patients who demonstrated ≥50% improvement in facial Vitiligo Area Scoring Index scores by week 24 (group 1) and those who did not (group 2).

Design: This was a posthoc analysis of a multicenter, randomized, double-blind, vehicle-controlled, phase 2 study in which screening was conducted between June 7, 2017 and March 21, 2018.

Dermatology's role in the fight against human trafficking: A report from the AAD Ad Hoc Task Force and call to action.

While the majority of American Academy of Dermatology members have some broad awareness of human trafficking, most are not aware of it in their communities or of the skin signs that could prompt identification of those being exploited, and have requested educational resources to assist patients affected by trafficking. The American Academy of Dermatology Ad Hoc Task Force on Dermatologic Resources for the Intervention and Prevention of Human Trafficking has been working to develop relevant resources, including an online toolkit on the American Academy of Dermatology website: https://www.aad.

Worldwide expert recommendations for the diagnosis and management of vitiligo: Position statement from the International Vitiligo Task Force Part 1: towards a new management algorithm.

Background: The treatment of vitiligo can be challenging and depends on several factors such as the subtype, disease activity, vitiligo extent, and treatment goals. Vitiligo usually requires a long-term approach. To improve the management of vitiligo worldwide, a clear and up-to-date guide based on international consensus with uniform stepwise recommendations is needed.

Worldwide expert recommendations for the diagnosis and management of vitiligo: Position statement from the international Vitiligo Task Force-Part 2: Specific treatment recommendations.

Background: The treatment of vitiligo can be challenging. Up-to-date agreed consensus recommendations on the use of topical and systemic therapies to facilitate the clinical management of vitiligo are currently lacking.

Objectives: To develop internationally agreed-upon expert-based recommendations for the treatment of vitiligo.

Mental Health and Psychosocial Quality-of-Life Burden Among Patients With Vitiligo: Findings From the Global VALIANT Study.

Importance: Patients with vitiligo often have impaired quality of life (QOL) and experience substantial psychosocial burden.

Objective: To explore the global association of vitiligo with QOL and mental health from the patient perspective.

Design, Setting, And Participants: This qualitative study of the cross-sectional population-based Vitiligo and Life Impact Among International Communities (VALIANT) study was conducted from May 6, 2021, to June 21, 2021.

Decades of beauty: Achieving aesthetic goals throughout the lifespan.

Background: Several elements, including age, influence judgments of beauty and attractiveness. Aging is affected by intrinsic factors (e.g.

A Photo-degradable Crosslinker for the Development of Light-responsive Protocell Membranes.

The achievement of light-responsive behaviours is an important target for protocell engineering to allow control of fundamental protocellular processes such as communication via diffusible chemical signals, shape changes or even motility at the flick of a switch. As a step towards this ambitious goal, here we describe the synthesis of a novel poly(ethylene glycol)-based crosslinker, reactive towards nucleophiles, that effectively degrades with UV light (405 nm). We demonstrate its utility for the fabrication of the first protocell membranes capable of light-induced disassembly, for the photo-generation of patterns of protocells, and for the modulation of protocell membrane permeability.

Exploring the natural and treatment history of vitiligo: perceptions of patients and healthcare professionals from the global VALIANT study.

Background: Vitiligo is a chronic autoimmune disease affecting melanocytes, resulting in skin depigmentation. Patients with vitiligo often have reduced quality of life and comorbid autoimmune conditions and have reported a lack of available treatments for their vitiligo.

Objectives: The Vitiligo and Life Impact Among International Communities (VALIANT) study is the first global survey to explore the natural history and management of vitiligo from the perspectives of patients and healthcare professionals (HCPs).
