OBJECTIVE: There are clinical differences in healthy skin requirements and skin-aging features by race and ethnicity. However, individuals of color are underrepresented in dermatology-related medical information. We sought to gather information from women of color regarding their attitudes about the importance of the prevention of skin aging, available information, and perception of representation in skin-aging prevention information. METHODS: This study involved an observational, cross-sectional, online survey of women aged 18 to 70 years residing in the United States. Participants were placed into one of seven cohorts based on self-reported race/ethnicity. Relative frequencies of responses were compared across cohorts; adjusted logistic regression was used to assess perception of representation in skin-aging prevention information. RESULTS: The mean age of the 1,646 participants was 44.4 years. The mean (standard deviation) rating (from 0, "not at all important" to 10, "extremely important") of the importance of the prevention of skin aging ranged from 7.3 to 8.2 across the seven cohorts. All cohorts reported the most trusted source of information for skin-aging prevention products and treatments was a skin-care professional, but not all cohorts believed they are well represented in available sources of information. Older age, lower median household income, and a race/ethnicity of Black, Asian, "Other," and "More Than One Race" were less likely to report being well represented. LIMITATIONS: People without internet access could not participate, potentially excluding some older and lower-income groups. CONCLUSION: Women of color are less likely to feel represented in available information on the prevention of skin aging. [ABSTRACT FROM AUTHOR]

Background. Hispanics diagnosed with cutaneous melanoma are more likely to present at advanced stages but the reasons for this are unknown. We identify census tracts at high risk for late stage melanoma diagnosis (LSMD) and examine the contextual predictors of LSMD in California, Texas, and Florida. Methods. We conducted a cross-sectional study using geocoded state cancer registry data. Using hierarchical multilevel logistic regression models we estimated ORs and 95% confidence intervals for the impact of socioeconomic, Hispanic ethnic concentration, index of dissimilarity, and health resource availability measures on LSMD. Results. We identified 12,493 cases. In California, late stage cases were significantly more likely to reside within census tracts composed mostly of Hispanics and immigrants. In Texas, LSMD was associated with residence in areas of socioeconomic deprivation and a higher proportion of immigrants. In Florida, living in areas of low education attainment, high levels of poverty, and a high percentage of Hispanic residents was significantly associated with LSMD. Residential segregation did not independently affect LSMD. Conclusion. The influence of contextual predictors on LSMD varied in magnitude and strength by state, highlighting both the cosegregation of social adversity and poverty and the complexity of their interactions.

Cutaneous melanoma is a significant public health concern, accounting for thousands of deaths annually in the US. Early detection and diagnosis are critical given the poor prognosis and limited treatment options of advanced-stage disease. While non-Hispanic whites have higher incidence rates of melanoma, Hispanics are typically diagnosed at later disease stages and suffer higher morbidity and mortality. Currently, there is a paucity of literature investigating the root causes underlying these trends among Hispanics. Given that Hispanics are the most rapidly expanding demographic segment in the US, it is essential for cancer control efforts to elucidate the major determinants of their poor melanoma outcomes. Herein, we use the social ecological model as a framework to explore the multitude of influences on melanoma disparities among Hispanics and provide recommendations for planning future studies and interventions.

Objective: To determine whether differences in race and ethnicity affect the usage of dermatological services. Methods: Data from the National Ambulatory Medical Care Survey were used to study trends in ethnic/race rates of outpatient dermatology office visits among publicly and privately insured patients from 2005-2010. In multivariable models, we explored the magnitude of ethnic/race differences in dermatology visit attendance for patients with public vs. private insurance. Results: From 2005-2010, dermatology visit utilization increased among insured Hispanics, but not among insured non-Hispanic Blacks or whites. Visits were less frequent by those with public insurance compared to private insurance. Privately and publicly insured visits were less common for non-Hispanic Blacks and Hispanics compared to whites after adjustment for patient demographics and primary visit diagnosis. Racial and ethnic differences in visit utilization rates were most apparent among non-referred visits. However, primary diagnoses for non-referred visits were similar across races and ethnicities, which suggests that differences in utilization may result from factors unrelated to clinical indications for care. Conclusion: Ethnic/race differences in the use of dermatological services in the United States may result from patient preferences for dermatologic care or health system related factors (e.g., insurance coverage regulations).

Introduction: Software to predict the impact of aging on physical appearance is increasingly popular. But it does not consider the complex interplay of factors that contribute to skin aging. Objectives: To predict the +15‐year progression of clinical signs of skin aging by developing Causal Bayesian Belief Networks (CBBNs) using expert knowledge from dermatologists. Material and methods: Structures and conditional probability distributions were elicited worldwide from dermatologists with experience of at least 15 years in aesthetics. CBBN models were built for all phototypes and for ages ranging from 18 to 65 years, focusing on wrinkles, pigmentary heterogeneity and facial ptosis. Models were also evaluated by a group of independent dermatologists ensuring the quality of prediction of the cumulative effects of extrinsic and intrinsic skin aging factors, especially the distribution of scores for clinical signs 15 years after the initial assessment. Results: For easiness, only models on African skins are presented in this paper. The forehead wrinkle evolution model has been detailed. Specific atlas and extrinsic factors of facial aging were used for this skin type. But the prediction method has been validated for all phototypes, and for all clinical signs of facial aging. Conclusion: This method proposes a skin aging model that predicts the aging process for each clinical sign, considering endogenous and exogenous factors. It simulates aging curves according to lifestyle. It can be used as a preventive tool and could be coupled with a generative AI algorithm to visualize aging and, potentially, other skin conditions, using appropriate images. [ABSTRACT FROM AUTHOR]

The article discusses the role of P2X7 receptors and Pannexin 1 (PANX1) proteins in melanoma. Topics discussed include association of chronic inflammation with melanoma progression, role of P2X7 in inflammasome activation, pro-metastatic effects of interleukin IL-1β, and investigation of inflammasome- mediated pathways to treat melanoma.

To review the literature on atopic dermatitis (AD) clinical trials published in the United States between 2000 and 2009 to examine the representation of racial and ethnic minorities in those trials and determine the extent to which investigators reported on demographic variables and performed a subanalysis. A PubMed search was performed including all clinical trials for management of AD published between 2000 and 2009. Three reviewers analyzed articles matching the search criteria. Data recorded included incorporation of demographic data at baseline and in the analysis and result interpretations. Of 645 PubMed search results, only 78 articles originated in the United States and fit the search criteria; 59.5% of these included reports of race or ethnicity. Of the studies reporting race or ethnicity, the subject population mainly included 62.1% white, 18.0% black, 6.9% Asian, and 2.0% Hispanic. Despite increasing awareness in the United States of the importance of reporting demographic data in clinical trials, there has been no significant improvement in reporting in AD clinical trials over the past 10 years. When reporting occurs, the categorization of ethnicities, methods of reporting data, and incorporation of the data into the results are lacking or flawed. In addition, aside from blacks, U.S. minorities appear to be underrepresented in AD clinical trials. [ABSTRACT FROM AUTHOR]

Background: After nonelective (i.e., semiurgent, urgent and emergent) surgeries, patients discharged from hospitals are at risk of readmissions, emergency department visits or death. During the coronavirus disease 2019 (COVID-19) pandemic, we are undertaking the Post Discharge after Surgery Virtual Care with Remote Automated Monitoring Technology (PVC-RAM) trial to determine if virtual care with remote automated monitoring (RAM) compared with standard care will increase the number of days adult patients remain alive at home after being discharged following nonelective surgery. Methods: We are conducting a randomized controlled trial in which 900 adults who are being discharged after nonelective surgery from 8 Canadian hospitals are randomly assigned to receive virtual care with RAM or standard care. Outcome adjudicators are masked to group allocations. Patients in the experimental group learn how to use the study's tablet computer and RAM technology, which will measure their vital signs. For 30 days, patients take daily biophysical measurements and complete a recovery survey. Patients interact with nurses via the cellular modem–enabled tablet, who escalate care to preassigned and available physicians if RAM measurements exceed predetermined thresholds, patients report symptoms, a medication error is identified or the nurses have concerns they cannot resolve. The primary outcome is number of days alive at home during the 30 days after randomization. Interpretation: This trial will inform management of patients after discharge following surgery in the COVID-19 pandemic and offer insights for management of patients who undergo nonelective surgery in a nonpandemic setting. Knowledge dissemination will be supported through an online multimedia resource centre, policy briefs, presentations, peer-reviewed journal publications and media engagement.

Mycosis fungoides, the most common form of cutaneous T-cell lymphoma, has a higher incidence and poorer prognosis in African-Americans. The factors that may be contributing to this disparity are presented in the context of a health disparities framework that includes discussion of patient-related factors such as race/ethnicity, socioeconomic status, and biological differences, provider-related factors such as patient-provider communication and the competing demands for providers' time, and health care system-related factors such as access to health care and workforce diversity. The changing demographics of the USA emphasize the need to understand and address health disparities in mycosis fungoides and other dermatologic diseases. The framework presented here can be used to examine disparities in other dermatologic conditions and advance health disparities research in dermatology. [ABSTRACT FROM AUTHOR]

Since their earliest description, keloids and hypertrophic scars have beleaguered patients and clinicians alike. These scars can be aesthetically disfiguring, functionally debilitating, emotionally distressing, and psychologically damaging, culminating in a significant burden for patients. Our current understanding of keloid pathophysiology has grown and continues to advance while molecular biology, genetics, and technology provide ever-deepening insight into the nature of wound healing and the pathologic perturbations thereof. Greater understanding will lead to the development and application of refined therapeutic modalities. This article provides an overview of our current understanding of keloids, highlighting clinical characteristics and diagnostic criteria while providing a comprehensive summary of the many therapeutic modalities available. The proposed mechanism, application, adverse events, and reported efficacy of each modality is evaluated, and current recommendations are summarized. [ABSTRACT FROM AUTHOR]

Background: Hepatitis C viral infection is a significant public health problem; 170 million persons are infected worldwide and the prevalence in the southern part of the United States exceeds two percent. Extrahepatic manifestations of hepatitis C viral infection are common; notably, 15-20% of patients will develop cutaneous manifestations of their disease. There are numerous dermatologic diseases associated with hepatitis C infection, including lichen planus, leukocytoclasticvasculitis, and porphyria cutaneatarda. Main observation: Recently, epidemiological studies have also demonstrated an association between hepatitis C infection and the development of non-Hodgkin lymphoma, especially marginal zone B-cell lymphoma. Herein we report the unusual case of a systemic marginal zone lymphoma in a patient with hepatitis C infection presenting clinically as localized lipoatrophy. Conclusion: Lipoatrophy can be a rare and diagnostically challenging presentation of secondary cutaneous marginal zone B-cell lymphoma. The importance of early recognition and detection cannot be over emphasized, as new and effective anti-viral treatments can lead to lymphoma regression in up to 75% of patients. To our knowledge, this is the first case of hepatitis C viral infection associated marginal zone lymphoma to present as localized lipoatrophy. [ABSTRACT FROM AUTHOR]
