A case-control study: epigenetic age acceleration in psoriasis.

Psoriasis (PsO) is a chronic inflammatory skin condition, often accompanied by psoriatic arthritis (PsA) and linked to various comorbidities and increased mortality rates. This study aimed to explore the relationship between PsO and accelerated biological aging, specifically focusing on epigenetic DNA methylation clocks. Using a matched case-control design, 20 PsO cases were selected along with age, race, and sex-matched 20 controls without PsO from the Skin Disease Biorepository at Brown Dermatology, Inc, Providence, Rhode Island. Blood samples retrieved from both groups were analyzed for DNA methylation, and epigenetic ages were calculated using DNA methylation clocks, including Horvath, Hannum, Pheno, SkinBlood, and Grim ages. Generalized estimation equations were employed to test the differences in epigenetic and chronological ages between PsO cases and controls, as well as within various subgroups in comparison to their respective controls. There were no statistically significant differences in epigenetic ages between PsO cases and controls. However, notably, PsO cases with PsA demonstrated an accelerated PhenoAge, compared to their matched controls. This study represents a pioneering investigation into the potential link between PsO and epigenetic aging, shedding light on the possibility of accelerated epigenetic aging in PsA, possibly associated with heightened inflammatory burden. These findings emphasize the systemic impact of PsA on the aging process, prompting the need for deeper exploration into autoimmune pathways, inflammation, and epigenetic modifications underlying PsO pathogenesis and aging mechanisms. Larger-scale studies with diverse populations are imperative to discern PsO subgroups experiencing accelerated biological aging and decipher the intricate interplay between PsO, inflammation, and aging pathways.

Racial Disparities in the Treatment of Hidradenitis Suppurativa: An Analysis of Data from the National Ambulatory Medical Care Survey.

Hidradenitis suppurativa (HS) is a painful, disfiguring, chronic inflammatory disease affecting the axillary, inframammary, and groin regions. Black Americans are disproportionately affected by HS. Structural barriers may be responsible for a lack of better prevention and management. This paper discusses possible reasons that may lead to a more severe presentation and barriers to treatment.

Host and primary tumor factors for the development of multiple cutaneous squamous cell carcinomas among a retrospective cohort in Rhode Island.

INTRODUCTION: Risk factors for a primary cutaneous squamous cell carcinoma (CSCC) are well-established; however, the host and primary tumor risk factors for subsequent CSCC have not been fully explored. METHODS: We performed a retrospective chart review of patients diagnosed with CSCC in an academic dermatology clinic in Rhode Island from 2016-2019. Logistic regression was used to evaluate the associations between host factors and multiple CSCC and between primary tumor characteristics and the risk of subsequent CSCC. Adjusted odds ratios (aORs) and 95% CIs were calculated. RESULTS: A total of 1312 patients with CSCC diagnoses were included. Host risk factors significantly associated with multiple CSCCs included: aged >80 years (aOR, 2.18; 95% CI, 1.46-3.31); history of: solid organ transplant (aOR, 2.41; 95% CI, 1.20-4.80); skin cancer (aOR, 1.96; 95% CI, 1.52-2.54); other cancer (aOR, 1.49; 95% CI, 1.11-2.00); family history of skin cancer (aOR, 1.36; 95% CI, 1.03-1.78); and actinic keratosis (aOR, 1.52; 95% CI, 1.18-1.95). Tumor location, diameter, histologic differentiation, and treatment were not significant predictors of subsequent CSCCs. LIMITATIONS: Study patients were predominantly White and from a single institution, limiting the generalizability of results. CONCLUSIONS: Certain host characteristics were associated with the development of subsequent CSCC, which may inform clinical guidelines for follow-up.

Tinea versicolour in underrepresented groups: An All of Us database analysis.

Tinea versicolour, used interchangeably with pityriasis versicolour (PV), is a superficial fungal infection of the stratum corneum caused by Malassezia furfur, a fungus of the normal flora of the skin. PV occurs when conditions favour proliferation of the organism's mycelial form, such as in environments with high temperatures/humidity, in immunodeficient/immunocompromised states, and during pregnancy. PV presents as numerous well- demarcated macules with a powdery scale. Prior epidemiologic studies have indicated that underrepresented groups defined by race experience a higher burden of PV as compared to White patients. However, the burden of PV in other underrepresented groups has not previously been examined, as underrepresented groups are frequently excluded from studies evaluating the impact of dermatologic disease. The new National Institute of Health All of Us Research Program (AoU) aims to build one of the world's largest and most diverse databases to promote elucidation of health disparities, particularly in communities that have been historically excluded from biomedical research.

Alopecia areata in underrepresented groups: preliminary analysis of the all of us research program.

Alopecia areata (AA) is an autoimmune condition characterized by patchy, nonscarring hair loss. Few studies of AA have adequately included participants from underrepresented groups when evaluating the burden of AA in the United States. We conducted a cross-sectional study of personal/demographic factors and AA using the ongoing All of Us (AoU) Research Program. AoU enrolls adults over 18 years either as direct volunteers or through participating Health Care Provider Organizations by prioritizing recruiting underrepresented groups. We linked data from surveys and electronic health records (EHRs) to estimate the prevalence of AA by race/ethnicity, physical disability, sexual orientation/gender identity (LGBTQIA +), income, and education. The latest AoU release (version 5) includes 329,038 participants. Average age was 51.8 years (standard deviation, SD 16.7), and 60.2% of participants were female. Of these, 251,597 (76.5%) had EHR data and 752 were diagnosed with AA (prevalence, 0.30%; 95% CI 0.28-0.32). We used multivariate logistic regression adjusted for age and other factors to estimate the odds ratio (OR) and 95% confidence intervals (CIs) for prevalence of AA. Compared to Whites, Blacks and Hispanics had higher odds of AA (OR, 1.72; 95% CI 1.39-2.11 and OR, 2.13; 95% CI 1.74-2.59, respectively). Lower odds of AA were observed in participants with less than a high school degree (OR, 0.80; 95% CI 0.59-1.08), household income ≤ $35,000 (OR, 0.67; 95% CI 0.54-0.83), and no health insurance (OR 0.35; 95% CI 0.20-0.56). In this diverse population of US adults, participants with skin of color had higher prevalence of AA. Lower prevalence of AA among individuals with lower education and income levels and those lacking health insurance may reflect limited access to dermatologic care and potentially higher levels of undiagnosed AA in these groups.

Onychomycosis in underrepresented groups: an all of us database analysis.

Few research studies evaluating the impact of dermatologic diseases in the United States (US) have adequately included underrepresented groups. All of Us (AoU) is an ongoing precision medicine-based research initiative by the National Institutes of Health (NIH) that facilitates research in populations traditionally underrepresented in biomedical research by prioritizing them for data collection. Our objective was to evaluate the burden of onychomycosis in underrepresented groups defined by the framework provided by AoU. The AoU Registered Tier dataset version 5 was used which includes data collected between May 30, 2017 and April 1, 2021. We conducted a cross-sectional analysis linking survey and electronic health record (EHR) data to estimate the prevalence of onychomycosis in underrepresented groups defined by race, ethnicity, age (≥ 75 years), disability, sexual orientation/gender identity (LGBTQIA +), income (annual household income ≤ $35 000) and education (less than a high school degree). The latest All of Us data release includes 329,038 participants. Of these, 251,597 (76%) had EHR data and 13,874 had onychomycosis (overall prevalence, 5.5%; 95% CI, 5.4-5.6). Multivariate analyses adjusted by tinea pedis, diabetes mellitus, immune compromise, nail psoriasis, and insurance status, in addition to the aforementioned variables, revealed that, compared with White participants, Black and Hispanic participants had a higher adjusted odds of onychomycosis (OR, 1.29; 95% CI, 1.23-1.36 and OR, 1.24; 95% CI, 1.17-1.31, respectively). Higher adjusted odds of onychomycosis were also observed in underrepresented groups. Our findings suggest a disproportionately high burden of onychomycosis in underrepresented groups, although further studies are needed to replicate our findings and address this disparity.

Immune-mediated diseases and subsequent risk of alopecia areata in a prospective study of US women.

INTRODUCTION: Alopecia areata (AA) is the most common form of immune-mediated hair loss. Studies have begun to establish the most frequent comorbid diseases of AA; however, results have been inconsistent with few prospective studies. METHODS: A total of 63,692 women in the Nurses' Health Study, 53-80 years, were prospectively followed from 2002 to 2014 to determine whether history of immune-mediated disease was associated with AA risk. Hazard ratios (HRs) and 95% confidence intervals (CIs) for AA in relation to immune-mediated conditions were computed using Cox proportional hazard models, adjusted for AA risk factors. RESULTS: 133 AA cases were identified during follow-up. Personal history of any immune-mediated disease was associated with increased AA risk (HR 1.72, 95% CI 1.24-2.37). History of systemic lupus erythematosus (HR 5.43, 95% CI 2.11-13.97), multiple sclerosis (HR 4.10, 95% CI 1.40-11.96), vitiligo (HR 3.13, 95% CI 1.08-9.10), psoriasis (HR 2.01, 95% CI 1.00-4.03), hypothyroidism (HR 1.88, 95% CI 1.30-2.71), and rheumatoid arthritis (HR 1.66, 95% CI 1.09-2.52) were associated with increased AA risk. History of inflammatory bowel disease or Graves' disease/hyperthyroidism was not significantly associated with AA risk. CONCLUSIONS: In this prospective study, personal history of immune-mediated diseases either individually or overall was associated with increased AA risk.

Tinea pedis in underrepresented groups: All of Us database analysis.

BACKGROUND: Tinea pedis is the most common form of dermatophytosis resulting in interdigital infections. All of Us (AoU) is a National Institute of Health initiative with an emphasis on patient populations traditionally underrepresented in biomedical research. OBJECTIVES: Our objective was to evaluate the burden of tinea pedis in underrepresented groups in the United States, utilising the novel AoU research program. METHODS: We analysed AoU Registered Tier dataset version 5, which includes data collected between 30 May, 2017, and 1 April, 2021. We conducted a cross-sectional analysis linking survey and electronic health record (EHR) data to estimate the prevalence of tinea pedis in underrepresented groups. RESULTS: All of Us data release includes 329,038 participants. Of these, 251,597 (76.5%) had electronic health record data and 6932 had tinea pedis (overall prevalence, 2.76%; 95% CI, 2.69-2.82). Multivariate analyses revealed that compared with White participants, Black and Hispanic participants had a higher adjusted odds of tinea pedis (OR, 1.29; 95% CI, 1.20-1.38 and OR, 1.38; 95% CI, 1.28-1.48, respectively). Higher adjusted odds of tinea pedis were observed in underrepresented groups defined by: age > =75 years (OR, 1.45; 95% CI, 1.33-1.57), LGBTQ status (OR, 1.17; 95% CI, 1.09-1.27), less than a high school education (OR, 1.22; 95% CI, 1.11-1.34), income <$35,000 (OR, 1.09; 95% CI, 1.02-1.16) and physical disability (OR, 1.56; 95% CI, 1.08-1.24). CONCLUSIONS: Our findings are consistent with overall age, and gender-specific prevalence estimates from prior epidemiologic studies, validating the scientific consistency of the new AoU database. Additionally, there may be an increased burden of tinea pedis among Black and Hispanic individuals.

An Analysis of Information Sources of YouTube Videos Pertaining to Tattoo Removal: Cross-Sectional Study.

Background: The American Academy of Dermatology and the Food and Drug Administration recommend consultation with a dermatologist prior to undergoing laser tattoo removal. However, non-health care professionals offer tattoo removal. Understanding the information available on the internet for patients regarding tattoo removal is important given that individuals are increasingly consulting digital sources to make decisions regarding skin care. Prior research has identified that YouTube contains misinformation on dermatologic health. Objective: Here, we present a cross-sectional study that determined the sources of information in YouTube videos that discuss tattoo removal and described the content presented to viewers. Methods: Using the query "tattoo removal," we reviewed English-language YouTube videos that explicitly discussed tattoo removal. The following data were recorded: profession of the presenter, tattoo removal method discussed, whether an explicit recommendation to see a dermatologist or physician was present in the video, and number of views. Results: We analyzed 162 YouTube videos. We found that the majority were presented by non-health care professionals (n=125, 77%), with only 4 (3.7%) records of this subset recommending viewers to seek consultation from a dermatologist to ensure safe and adequate tattoo removal. Conclusions: Based on our findings, we recommend that dermatologists and other health care professionals provide high-quality, evidence-based information to viewers on tattoo removal and encourage dermatology societies to share via their social media platforms information about the importance of consulting a dermatologist for tattoo removal.

Epidemiology and Survival of Kaposi's Sarcoma by Race in the United States: A Surveillance, Epidemiology, and End Results Database Analysis.

The introduction of highly active antiretroviral treatment (HAART) for acquired immunodeficiency syndrome (AIDS) has led to a significant decrease in the incidence of Kaposi's sarcoma (KS) in recent years. However, a concomitant increase in racial disparities in KS has arisen. Here, we analyze data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program for epidemiology and survival of Kaposi's sarcoma by race. The highest incidence was observed among Black patients (incidence rate (IR), 1.189; 95% confidence interval (CI), 1.092-1.189), followed by White patients (IR, 0.486; 95% CI, 0.473-0.498). Relative survival at 1, 3, and 5 years differed significantly by race, with White patients having the highest survival rates (84.26%, 77.79%, and 74.79% at 1, 3, and 5 years respectively) and Black patients demonstrating the lowest (71.50%, 61.37%, and 57.38%), with intermediate survival rates in Asians/Pacific Islanders (AAPI) (80.62%, 71.19%, and 67.28%) and American Indians/Alaska Natives (AIAN) (80.56%, 61.45%, and 61.45%). We conclude that there are significant racial disparities in the incidence, epidemiology, and survival of KS.

Racial disparities in the management of skin ulcers: an analysis of the National Ambulatory Medical Care Survey, 2012-2018.

PURPOSE: Racial/ethnic differences in health care are pervasive in the USA, but the literature is limited with regards to racial disparities in the treatment of dermatologic diseases. MATERIALS AND METHODS: Data on the management of skin ulcers was analyzed from the National Ambulatory Medical Care Survey (NAMCS) from 2012 to 2018. Data distributions between Blacks and Whites, chi-squared statistics, and Fisher Exact Tests were computed to identify significant differences in demographic factors, patient encounter characteristics, and medication prescribed, as a function of race. RESULTS: Blacks were less likely than Whites to receive: care by a physician (p = .0389), a skin examination (p < .0001), or cryotherapy (p < .0175). Blacks were more likely to be seen by a nurse practitioner (p = .0359). Whites were 6.698 times more likely than Blacks to have a follow up visit scheduled after 2 months or more. CONCLUSIONS: Our data suggests that among outpatient visits for skin ulcers in the USA, racial disparities exist in the probability of seeing a physician, receiving treatment, and follow-up care. Further research must be conducted and interventions implemented in order to combat racial disparities in Black patients' access to dermatologic treatment for skin ulcers.
