RESUMO

Sleep is crucial for preserving both physical and mental health, including skin health. Presently, there is a burgeoning interest in the use of herbal and natural ingredients to mitigate the adverse effects of sleep disorders. In this 4-week, randomized, double-blind, controlled trial, 70 subjects with sleep disorders were randomly assigned to receive either a placebo or a Poria cocos, Ziziphus spinose, and GABA (PZG) supplement (10 mL per day). Total sleep duration was detected by wrist actigraphy, and sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Skin conditions were evaluated based on assessments of skin hydration, glossiness elasticity, color, severity of wrinkles, and skin roughness. After 4 weeks, the total sleep duration significantly increased by 12.96% (p = .006) and the PSQI score notably decreased by 59.94% (p = .000) compared to the baseline. Notably, compared to the baseline conditions, skin hydration, radiance, elasticity, firmness, wrinkle severity, and roughness were significantly improved in the PZG group. In addition, the PZG group demonstrated significantly greater improvements than the placebo group in terms of changes from baseline in total sleep duration, PSQI score, skin hydration, wrinkle severity, and skin roughness. The present results demonstrated that the combined intake of herbs and GABA can improve sleep quality and enhance skin health without adverse effects.

RESUMO

This study investigates the communication between skin cells, specifically melanocytes, keratinocytes, and fibroblasts, which is crucial for the process of melanin production known as melanogenesis. We aimed to understand the role of melanocyte exosomes in regulating melanogenesis and to uncover the microRNAs influencing this process. We isolated exosomes and characterized them using advanced microscopy and protein analysis to achieve this. We conducted experiments on melanoma cells to study melanin production regulation and examined how exosomes influenced gene expression related to melanogenesis. The results revealed that melanocyte exosomes increased certain types of tyrosinases, thereby enhancing melanin production. Furthermore, we acquired the miRNA profile of exosomes and hypothesized that specific siRNAs, such as miR-21a-5p, could potentially facilitate melanin synthesis. Our findings shed light on the importance of exosomes in skin health and provide valuable insights into intercellular communication mechanisms. Understanding these processes can pave the way for innovative therapies to treat melanin-related disorders and maintain healthy skin.

RESUMO

Incontinence-associated dermatitis, previously and sometimes still referred to as moisture lesions or moisture damage, is a commonly seen contact dermatitis that is a reactive response of the skin to chronic contact to urine and faecal matter. Understanding the etiology is fundamental to creating a skin care plan and successfully prevention. Systemic reviews and studies have shown that the continued variability in management results from a combination of knowledge base, observation, diagnosis, and product selection. This article aims to improve clinicians' understanding of incontinence-associated dermatitis and its management.

RESUMO

Wearable bioelectronics represents a significant breakthrough in healthcare settings, particularly in (bio)sensing which offers an alternative way to track individual health for diagnostics and therapy. However, there has been no notable improvement in the field of cancer, particularly for skin cancer. Here, a wearable bioelectronic patch is established for transdermal sensing of the melanoma biomarker, tyrosinase (Tyr), using a microneedle array integrated with a surface-bound chemo-responsive smart probe to enable target-specific electrochemical detection of Tyr directly from human skin tissue. The results presented herein demonstrate the feasibility of a transdermal microneedle sensor for direct quantification of enzyme biomarkers in an ex vivo skin model. Initial performance analysis of the transdermal microneedle sensor proves that the designed methodology can be an alternative for fast and reliable diagnosis of melanoma and the evaluation of skin moles. The innovative approach presented here may revolutionize the landscape of skin monitoring by offering a nondisruptive means for continuous surveillance and timely intervention of skin anomalies, such as inflammatory skin diseases or allergies and can be extended to the screening of multiple responses of complementary biomarkers with simple modification in device design.

RESUMO

Background Acne vulgaris is a prevalent dermatological condition worldwide, with its impact significantly influenced by various genetic, environmental, and lifestyle factors. Despite its global prevalence, data on acne's prevalence and risk factors in Saudi Arabia remain sparse. This study aims to fill this gap by examining the prevalence of acne vulgaris and identifying associated lifestyle and environmental risk factors within the Saudi population. Methodology Employing a cross-sectional survey-based design, this study collected data from a representative sample of the Saudi population aged 18 years and older. Participants were selected through stratified random sampling and completed a self-administered online questionnaire covering demographic information, lifestyle factors, and acne history. Statistical analyses, including descriptive statistics, chi-square tests, and multivariable logistic regression, were utilized to identify significant risk factors associated with acne vulgaris. Results The survey, completed by 1,983 participants, revealed a diverse age distribution with a slight predominance of the 21-25-year age group (32.5%). Gender distribution was nearly balanced (52% female, 48% male), and the majority were single (67.3%). Lifestyle assessments indicated varied water intake, with a significant portion consuming less than 1-2 L per day. Sleep duration for most fell within the 5-7 hours range. Fast food consumption was frequent among 24% of respondents, and physical activity levels showed 40% of participants exercised minimally. Notably, 72% reported a history of acne, predominantly beginning between ages 16 and 20. Acne was mainly mild to moderate in severity and primarily affected the face. Treatment was sought by 60%, with a preference for topical solutions. Awareness around acne causes was moderate, with a high consensus on the impact of stress and diet on acne development. Conclusions Acne vulgaris in Saudi Arabia is significantly associated with various modifiable lifestyle factors, suggesting that interventions focusing on lifestyle modifications may be effective in managing and preventing acne. This study advocates for the integration of lifestyle counseling into acne treatment protocols, offering a holistic approach to managing this pervasive condition.

RESUMO

BACKGROUND: Well-being is commonly communicated across industries; however, experimental understanding how human perceive skin health and skin stresses are not sufficient. MATERIALS AND METHODS: Image analysis algorithm, a* gradient, was developed to evaluate spatial pattern and shape of red signal on skin. Human perception for skin health and stresses were compared with technical measurements in two visual perception studies. RESULTS: a* gradient correlated with perceived Inflamed Skin (R = 0.73, p < 0.01), Stressed Skin (R = 0.79, p < 0.01), Sensitive Skin (R = 0.75, p < 0.01), Healthy Skin (R = -0.83, p < 0.01), and Start Aging (R = 0.75, p < 0.01). CONCLUSIONS: Disordered spatial pattern of redness signal drives human perception of skin health, stress, and aging. This new skin index of redness signal shows higher correlation with those human perception than basal a* mean, unevenness of a*, and other conventional skin color attributes.

RESUMO

INTRODUCTION: Senescent cells contribute to age-related tissue deterioration, including the skin, which plays important roles in overall health and social interactions. This study aimed to assess the effects of the senotherapeutic peptide, OS-01 (a.k.a. Pep 14), on skin. METHODS: A 12-week split-face, double-blinded, vehicle-controlled study involving 22 participants was conducted. The OS-01-containing formulation was applied to one side of the face, while the other side received an identical control formulation lacking the peptide. Skin characteristics were assessed using instrumental measurements, expert clinical grading, and subjective questionnaires. RESULTS: Results showed that the OS-01 formulation significantly improved one aspect of skin barrier function, as evidenced by reduced trans-epidermal water loss compared to both baseline and vehicle control. Expert grading and Antera 3D image analysis revealed a reduction in wrinkle appearance and indentation in the periorbital area, and improved skin texture and radiance on both sides of the face, with the OS-01-containing formulation demonstrating superior results. Participants also perceived improvements in skin hydration, smoothness, radiance, and overall appearance. CONCLUSION: The findings suggest that the OS-01 formulation promotes skin health by strengthening the skin barrier, protecting against dehydration, reducing the appearance of wrinkles, and improving skin texture and radiance. These effects are likely attributed to the senotherapeutic properties of OS-01 in reducing cellular senescence and its associated detrimental effects.

RESUMO

Adequate nutrition during childhood and adolescence is crucial for proper neurological, musculoskeletal, immunological, and cardiometabolic health and development. Yet, disparities among socially underserved racial/ethnic groups in the United States (US) provide significant challenges to achieving adequate nutrition during these years of rapid growth and maturation. For example, Black children and adolescents are at greater risk for having food insecurity, lower-quality diets, obesity, and numerous associated health challenges that result from these disparities compared to their White peers. A growing body of evidence indicates that improving diet quality is critical for improving childhood and adolescent health and well-being, and that the diverse nutritional profile and bioactive compounds found within dairy foods may play multiple roles in promoting proper growth and development during these life stages. Therefore, to support overall health and development among Black youth, greater education and implementation efforts are needed to help this population meet the national dietary recommendations of 2.5 to 3 servings of dairy foods per day. Continuing to fall short of these recommendations puts Black children and adolescents at risk of multiple nutrient inadequacies and health disparities that can have lifelong impacts on disease development, mental health, and quality of life. This review presents the state of knowledge on health disparities and modifiable nutritional strategies involving milk and dairy foods to support the growth and maturation of children and adolescents, with a special focus on Black youth in the US.

RESUMO

BACKGROUND: Most skin-related traits have been studied in Caucasian genetic backgrounds. A comprehensive study on skin-associated genetic effects on underrepresented populations such as Vietnam is needed to fill the gaps in the field. OBJECTIVES: We aimed to develop a computational pipeline to predict the effect of genetic factors on skin traits using public data (GWAS catalogs and whole-genome sequencing (WGS) data from the 1000 Genomes Project-1KGP) and in-house Vietnamese data (WGS and genotyping by SNP array). Also, we compared the genetic predispositions of 25 skin-related traits of Vietnamese population to others to acquire population-specific insights regarding skin health. METHODS: Vietnamese cohorts of whole-genome sequencing (WGS) of 1008 healthy individuals for the reference and 96 genotyping samples (which do not have any skin cutaneous issues) by Infinium Asian Screening Array-24 v1.0 BeadChip were employed to predict skin-associated genetic variants of 25 skin-related and micronutrient requirement traits in population analysis and correlation analysis. Simultaneously, we compared the landscape of cutaneous issues of Vietnamese people with other populations by assessing their genetic profiles. RESULTS: The skin-related genetic profile of Vietnamese cohorts was similar at most to East Asian cohorts (JPT: Fst = 0.036, CHB: Fst = 0.031, CHS: Fst = 0.027, CDX: Fst = 0.025) in the population study. In addition, we identified pairs of skin traits at high risk of frequent co-occurrence (such as skin aging and wrinkles (r = 0.45, p = 1.50e-5) or collagen degradation and moisturizing (r = 0.35, p = 1.1e-3)). CONCLUSION: This is the first investigation in Vietnam to explore genetic variants of facial skin. These findings could improve inadequate skin-related genetic diversity in the currently published database.

RESUMO

BACKGROUND: Indigenous children in colonised nations experience high rates of health disparities linked to historical trauma resulting from displacement and dispossession, as well as ongoing systemic racism. Skin infections and their complications are one such health inequity, with the highest global burden described in remote-living Australian Aboriginal and/or Torres Strait Islander (hereafter respectfully referred to as Aboriginal) children. Yet despite increasing urbanisation, little is known about the skin infection burden for urban-living Aboriginal children. More knowledge is needed to inform service provision, treatment guidelines and community-wide healthy skin strategies. In this pilot study, we aimed to test the feasibility and design of larger multi-site observational studies, provide initial descriptions of skin disease frequency and generate preliminary hypotheses of association. METHODS: This project has been co-designed with local (Noongar) Elders to provide an Australian-first description of skin health and disease in urban-living Aboriginal children. In collaboration with an urban Aboriginal Community Controlled Health Organisation (Derbarl Yerrigan Health Service), we conducted a week-long cross-sectional observational cohort study of Aboriginal children (0-18 years) recruited from the waiting room. Participants completed a questionnaire, skin examination, clinical photos, and swabs and received appropriate treatment. We assessed the feasibility and impact of the pilot study. RESULTS: From 4 to 8 October 2021, we recruited 84 Aboriginal children of whom 80 (95%) were urban-living. With a trusted Aboriginal Health Practitioner leading recruitment, most parents (or caregivers) who were approached consented to participate. Among urban-living children, over half (45/80, 56%) of parents described a current concern with their child's skin, hair and/or nails; and one-third (26/80, 33%) reported current itchy skin. Using a research-service model, 27% (21/79) of examined urban-living participants received opportunistic same-day treatment and 18% (14/79) were referred for later review. CONCLUSIONS: This co-designed pilot study to understand skin health in urban-living Aboriginal children was feasible and acceptable, with high study participation and subsequent engagement in clinical care observed. Co-design and the strong involvement of Aboriginal people to lead and deliver the project was crucial. The successful pilot has informed larger, multi-site observational studies to more accurately answer questions of disease burden and inform the development of healthy skin messages for urban-living Aboriginal children.

RESUMO

OBJECTIVE: To determine the incidence and site of any adverse effects of wearing face masks via an online questionnaire. METHODS: Healthcare workers in a dental hospital who wear Respiratory Protective Equipment (RPE) were invited to participate. An online questionnaire was used to identify adverse effects as a result of wearing face masks and possible remedies. RESULTS: Red marks (72.1 %) and indentations (66.7 %) were the most frequently reported issues with increased use of the RPE. The bridge of the nose and cheeks were the most frequently reported sites of facial skin problems, such as blanching (54.1 % and 42.2 %, respectively) and pressure damage (42.3 % and 24.3 %, respectively). Overall perceived facial skin health deteriorated strongly and significantly (P < 0.001) following the use of RPE, where the mean skin health score (0 = best possible skin health and 10 = worst possible skin health) increased from 2.68 to 4.76. Broadly, there was increased discomfort with increased hours of use of RPE per day (P = 0.049). 71 % of participants said that they generally felt safe or very safe using RPE. CONCLUSION: The facial skin health of respondents deteriorated strongly after the use of RPE. Guidelines for using RPE should be made clearer. A greater range of face mask sizes or bespoke masks should be made available to improve the fit and wearability, as well as to reduce the frequency and incidence of surface skin problems. CLINICAL SIGNIFICANCE: This study has identified the factors influencing adverse skin reactions from face mask use, which can be used to inform face mask designers and manufacturers to improve the fit and wearability of face masks.

RESUMO

INTRODUCTION: Air pollution in North America has intensified due to wildfires in recent years. In 2023, the wildfires in the Canadian province of Quebec caused a southward spread of pollutants, negatively affecting air quality and thereby aggravating certain health conditions in northeastern USA. This study examines the impact of air pollution on atopic dermatitis (AD) and skin health and how wildfires can exacerbate the burden of disease. METHODS: Carbon monoxide levels measured by the U.S. Environmental Protection Agency (EPA) in the Boston region during the months following the Canadian wildfires of 2023 were collected from the U.S. EPA Outdoor Air Quality webpage. Patient records on dermatology clinic visits for dermatitis and eczema at the Mass General Brigham (MGB) hospital system, 300 miles from the wildfires, were examined, and the data compared with data from the corresponding months in 2019-2022 for historical control. No individual patient data were collected. RESULTS: A notable rise and atypical summer peak in carbon monoxide (CO) levels in the Boston region during 2023 correlated with a spike in AD, dermatitis, and eczema-related dermatology clinic visits within the MGB hospital system, as compared with the prior 4 years. CONCLUSION: The synchronized atypical peaks of CO levels and AD-related visits during the summer of 2023 highlight the potential impact of acute air pollution events such as wildfires on air quality and the consequences for skin health. Air pollution, exacerbated by wildfires, can damage the skin through the smoke and chemicals utilized for extinguishing fires, which contain multiple potential allergens and irritants to the skin, such as CO, particulate matter (PM2.5), and ammonium phosphates, triggering airway and skin inflammation and flares of AD. This issue disproportionately affects vulnerable populations, including low-income communities and the geriatric and pediatric populations. Healthcare professionals and government agencies must work together to improve air quality and purification policies and initiatives to lower the burden of skin disease, especially for vulnerable communities.

RESUMO

BACKGROUND: Curcumin is a polyphenolic compound present in turmeric (Curcuma longa). Curcumin, turmeric powder, and extracts are widely used in traditional Indian medicine and are active ingredients of dietary supplements and cosmeceutical products. The pharmacological properties of curcumin/turmeric as well as the studies performed in vitro, in animal models, and in volunteers have been the objects of a vast literature. Most of the clinical studies report on the effects of curcumin/turmeric administered orally, while only a few describe its topical applications. SUMMARY: This review focuses on clinical studies in which curcumin/turmeric was applied topically to treat various skin conditions based on its antioxidant, anti-inflammatory, and antimicrobial properties. KEY MESSAGES: The clinical studies employing curcumin/turmeric as the only active ingredient allow us to appreciate its therapeutic potential without confounding contributions coming from additional pharmacologically active substances present in the same formulation. Curcumin/turmeric was regarded as an attractive alternative to conventional drugs, such as corticosteroids and antibiotics, thanks to its characteristics of a safe and well-tolerated natural substance.

RESUMO

OBJECTIVE: To evaluate the impact of oral intake of Hyaluronic Acid (HA) on skin health. BACKGROUND: HA, an endogenous substance in the human body, plays a key role in skin health. However, its concentration in the skin decreases significantly with age. Previous studies suggested that oral intake of HA can supplement the body's HA level, but did not reveal the effects on different age groups and skin types. METHODS: A double-blind, randomized clinical trial with 129 female participants, covering young and elderly groups and differnet skin types, was conducted to assess the efficacy of orally administered HA on skin health. RESULTS: Oral administration of HA significantly promoted skin hydration after 2-8 weeks among both young and elderly groups. Skin tone improvement was observed after 4-8 weeks, while an increase in epidermal thickness was noted after 12 weeks. CONCLUSION: This study provides direct evidence supporting the clinical efficacy of oral intake of HA in promoting skin health.

RESUMO

Background: The developments in cosmetic sciences and technologies have generated a gap between the cosmetics and their users. Users including regular customers, clinicians, industry personnel, researchers, testing agencies, beauty salon workers, and mass media hardly possess the ability to distinguish truth from falsehood. The gap remained as one major reason for inappropriate cosmetics usage, insufficient efficacy, and even cosmetics adverse reactions (CARs). Methods: Aiming at enhancing the relevant practitioners' cosmetic and dermatologic sciences, we launched a cosmetic and dermatologic sciences continuing medical education (CME) since 2008. The objective of the current study was to evaluate the effectiveness of the CME. We summarized and analyzed the project for the last 15 years. Meanwhile, an online survey consisted of three parts was performed to evaluate the CME and to collect the trainees' comments. Results: A total of 3,923 trainees have participated in the CME project from 2008 to 2022. The trainees included clinicians, industry staffs, biomedical researchers, third-party cosmetics testing staffs, beauty salon staffs, students, and media staffs. The trainees had theory courses on cosmetic and dermatologic sciences, cosmetics DIY practice & video watching, and an optional guided tour during the 4.5-day CME. Eight hundred and twenty-three trainees and 586 control subjects responded to the online survey. The comprehensive test in the second part of the survey demonstrated that compared with the control group, the CME project significantly enhanced the trainees' perception and knowledge regarding the cosmetics formula sciences, basic dermatologic sciences, cosmetics usage, noninvasive measurements, new advances, CARs, and laws (p = 0.000). Trainees of all occupations ranked "basic dermatologic sciences and skin diseases" as the most significant sections. Trainees of all occupations believed the CME has contributed most in "understand the function & efficacy of cosmetics." We noticed the occupational variances. Over 97% of trainees were willing to recommend the CME to the others. Conclusion: The CME project significantly enhanced the trainees' cosmetic and dermatologic sciences, which bridged the gap between cosmetics and public skin health. This multidisciplinary CME also contributed to establishing an interdisciplinary interaction and cooperation platform for the multiple occupations involved in the public skin health maintenance and promotion.

RESUMO

The constant growth of the cosmetic industry, together with the scientific evidence of the beneficial properties of phytochemicals, has generated great interest in the incorporation of bioactive extracts in cosmetic formulations. This study aims to evaluate the bioactive potential of a mango peel extract for its incorporation into cosmetic formulations. For this purpose, several assays were conducted: phytochemical characterization; total phenolic content (TPC) and antioxidant potential; free-radical scavenging capacity; and skin aging-related enzyme inhibition. In addition, the extract was incorporated into a gel formulation, and a preliminary stability study was conducted where the accelerated (temperature ramp, centrifugation, and heating/cooling cycles) and long-term (storage in light and dark for three months) stability of the mango peel formulations were evaluated. The characterization results showed the annotation of 71 compounds, gallotannins being the most representative group. In addition, the mango peel extract was shown to be effective against the •NO radical with an IC50 of 7.5 mg/L and against the hyaluronidase and xanthine oxidase enzymes with IC50 of 27 mg/L and 2 mg/L, respectively. The formulations incorporating the extract were stable during the stability study. The results demonstrate that mango peel extract can be a by-product to be revalorized as a promising cosmetic ingredient.
