Effects of treatment methods on cutaneous melanoma related mortality and all-cause mortality in Texas: TCR-Medicare 2007-2017 database.

PURPOSE: The incidence of cutaneous melanoma is rising, and Melanoma related deaths are highest among people aged 65-74. Herein, we aim to understand the impact of novel and established melanoma treatment methods on CM related mortality and all-cause mortality. We further compared these effects among Hispanic and non-Hispanic Whites (NHW). METHODS: The data was extracted from the Texas Cancer Registry from 2007 to 2017. A Cox Proportional Hazard regression analysis was performed to assess treatment effect on melanoma mortality and all-cause mortality, with race-ethnicity as an effect modifier. RESULTS: A higher percentage of Hispanic patients presented with CM-related mortality (22.11%) compared to NHW patients (14.39%). In both the Hispanic and NHW, post-diagnosis radiation (HR = 1.610, 95% CI 0.984-2.634, HR = 2.348, 95% CI 2.082-2.648, respectively), post-diagnosis chemotherapy (HR = 1.899, 95% CI 1.085-3.322, HR = 2.035, 95% CI 1.664-2.489, respectively), and post-diagnosis immunotherapy (HR = 2.100, 95% CI 1.338-3.296, HR = 2.402, 95% CI 2.100-2.748) are each associated with an increased risk in CM-related mortality. Similar results were seen with post-diagnosis radiation (Hispanic HR = 1.640, 95% CI 1.121-2.400, NHW HR = 1.800, 95% CI 1.644-1.971), post-diagnostic chemotherapy (Hispanic HR = 1.457, 95% CI 0.898-2.364, NHW HR = 1.592, 95% CI 1.356-1.869), and post-diagnosis immunotherapy (Hispanic HR = 2.140, 95% CI 1.494-3.065, NHW HR = 2.190, 95% CI 1.969-2.435) with respect to all-cause mortality. Post-diagnosis surgery (HR = 0.581, 95% CI 0.395-0.856, HR = 0.622, 95% CI 0.571-0.678) had the opposite effect in CM-related mortality for Hispanics and NHWs respectively. CONCLUSION: Our results propose differences in all-cause and CM-only related mortality with separate treatment modalities, particularly with chemotherapy, radiation therapy and immunotherapy. In addition, this retrospective cohort study showed that health disparities exist in the Hispanic Medicare population of Texas with CM.

Integrating skin color assessments into clinical practice and research: A review of current approaches.

Skin color classification can have importance in skin health, pigmentary disorders, and oncologic condition assessments. It is also critical for evaluating disease course and response to a variety of therapeutic interventions and aids in accurate classification of participants in clinical research studies. A panel of dermatologists conducted a literature review to assess the strengths and limitations of existing classification scales, as well as to compare their preferences and utilities. We identified 17 skin classification systems utilized in dermatologic settings. These systems include a range of parameters such as UV light reactivity, race, ethnicity, and degree of pigmentation. The Fitzpatrick skin type classification is most widely used and validated. However it has numerous limitations including its conflation with race, ethnicity, and skin color. There is a lack of validation data available for the remaining scales. There are significant deficiencies in current skin classification instruments. Consensus-based initiatives to drive the development of validated and reliable tools are critically needed.

Understanding the Association Between Social Determinants of Health and Receipt of Immunotherapy for Melanoma.

PURPOSE: In this review article, we sought to elucidate how the social determinants of health, including socioeconomic status, education, neighborhood or physical environment, access to healthcare, and race/ethnicity, affect the likelihood of receiving immunotherapy, a novel and expensive treatment for melanoma.  Methods: The PubMed database was queried up to May 2023, for studies pertaining to health disparities in melanoma, including studies examining the utilization of immunotherapy agents for the treatment of melanoma across various social determinants of health. RESULTS: Disparities in the utilization of immunotherapy exist across various social determinants. A total of 10 studies were found to report on disparities in receipt of immunotherapy. These studies reported an association between insurance status, education level, socioeconomic status, as well as proximity to a cancer research center, and a lower likelihood of receiving immunotherapy. CONCLUSION: As the number of novel immunotherapy drugs grows, it is important to understand the various disparities affecting the delivery of immunotherapy across social determinants. The findings from this study can help to drive public health policy aimed at addressing inequities in the treatment of melanoma as well as other cancers.    J Drugs Dermatol. 2024;23(5):311-315. doi:10.36849/JDD.7803.

Recurrence of morphea after successful ultraviolet A1 phototherapy: A cohort study.

BACKGROUND: Studies support efficacy of ultraviolet (UV)A1 phototherapy, but little is known about recurrence after successful UVA1 treatment. OBJECTIVE: We sought to determine the frequency of recurrent activity after UVA1 phototherapy and variables associated with recurrence. METHODS: This was a case series and prospective cohort study of patients treated with UVA1 phototherapy with minimum 6 months of follow-up. Demographics, clinical features, and cumulative UVA1 dose were analyzed for association with recurrence. RESULTS: Of 37 patients, 46% (n = 17) had recurrence of active morphea lesions after successful UVA1 phototherapy. Two-year and 3-year (after the last UVA1 phototherapy treatment) recurrence rates were 44.5% (95% confidence interval 30.1%-62.2%) and 48.4% (95% confidence interval 33.2%-66.1%), respectively. The only variable associated with recurrence was duration of morphea before UVA1 (P value = .02, hazard ratio 1.15, 95% confidence interval 1.06-1.27). LIMITATIONS: The sample size limits conclusions. CONCLUSION: With the exception of increased duration of morphea, risk of recurrence is no different in adults and children, or between morphea subtypes, skin types, and medium- to high-dose regimens. This indicates treatment doses in the medium-high UVA1 range are adequate with respect to frequency of recurrence.

The role of skin trauma in the distribution of morphea lesions: a cross-sectional survey of the Morphea in Adults and Children cohort IV.

BACKGROUND: Skin trauma may play a role in the development of morphea lesions. The association between trauma and the distribution of cutaneous lesions has never been examined to our knowledge. OBJECTIVE: We sought to determine whether patients enrolled in the Morphea in Adults and Children (MAC) cohort exhibit skin lesions distributed in areas of prior (isotopic) or ongoing (isomorphic) trauma. METHODS: This was a cross-sectional analysis of the MAC cohort. RESULTS: Of 329 patients in the MAC cohort, 52 (16%) had trauma-associated lesions at the onset of disease. Patients with lesions in an isotopic distribution had greater clinical severity as measured by a clinical outcome measure (mean modified Rodnan Skin Score of 13.8 vs 5.3, P = .004, 95% confidence interval 3.08-13.92) and impact on life quality (mean Dermatology Life Quality Index score 8.4 vs 4.1, P = .009, 95% confidence interval 1.18-7.50) than those with an isomorphic distribution. Most frequent associated traumas were chronic friction (isomorphic) and surgery/isotopic. LIMITATIONS: Recall bias for patient-reported events is a limitation. CONCLUSION: Of patients in the MAC cohort, 16% developed initial morphea lesions at sites of skin trauma. If these findings can be confirmed in additional series, they suggest that elective procedures and excessive skin trauma or friction might be avoided in these patients.

IgG, IgM, and IgA antinuclear antibodies in discoid and systemic lupus erythematosus patients.

IgG antinuclear antibodies (ANAs) are elevated in patients with systemic lupus erythematosus (SLE) compared with patients with discoid lupus erythematosus (DLE). To provide an expanded immunologic view of circulating ANAs in lupus patients, we compared the expressions of IgG, IgM, and IgA ANAs in DLE and SLE patients. In this cross-sectional study, sera from age-, gender-, and ethnic-matched SLE (N = 35), DLE (N = 23), and normal patients (N = 22) were tested for IgG, IgM, and IgA ANAs using enzyme-linked immunosorbent assays (ELISAs) and indirect immunofluorescence (IIF) with monkey esophagus as substrate. ELISAs showed elevated levels of IgG ANA, IgM ANA, and IgG/IgM ANA ratios in SLE patients compared with DLE and normal patients. IgA ANA expression was higher in SLE and DLE patients versus normal patients. IIF studies showed higher percentages of patients positive for IgG, IgM, and IgA ANAs in the SLE group. Higher IgG/IgM ANA ratios in SLE than DLE show enhanced class-switching and a more sustained humoral response in SLE. They also suggest a potential connection of IgM ANAs with disease containment.

History of Race in America.

Racial and ethnic disparities exist across a wide range of disease areas and clinical services. Becoming familiar with the history of race in America, and how it has been used to structure laws or policies that drive inequities in the social determinants of health, even today, is necessary to mitigate these disparities across medicine.

Morphea and other localized forms of scleroderma.

PURPOSE OF REVIEW: Morphea, also known as localized scleroderma, is a disorder of excessive collagen deposition leading to thickening of the dermis and/or subcutaneous tissues and may cause significant morbidity. This review will describe new developments in the evaluation and management of morphea as well as its pathophysiology. The reader will be able to apply these findings to patient management. RECENT FINDINGS: The recent development of validated outcome measures (i.e. the localized scleroderma cutaneous assessment tool) as well as consensus treatment recommendations provide a platform for collaboration among specialties to develop both standardized assessment tools and therapeutic trials. New studies have also begun to investigate the immunological underpinnings of morphea. SUMMARY: The promise of evidence-based treatments for morphea in the near future will provide better care for patients with morphea and understanding its pathophysiology will lay groundwork for the development of new treatments.

A case study of the Scaffolding Clinical Practicum Model: is it culturally competent for Hispanic nursing students?

The Institute of Medicine, Office of Minority Health, and the Health Resources and Services Administration have called for culturally competent teaching methods to promote the success of Hispanic nursing students. The article responds to this call by analyzing an innovative clinical practicum teaching method, the Scaffolding Clinical Model, in relation to the cultural competence needs of Hispanic nursing students. The analysis is presented through a case study of a cohort of predominantly (90%) Hispanic baccalaureate nursing students at a university on the United States-Mexico border. The cultural competence of the Scaffolding Clinical Model is analyzed by identifying how well it acknowledges and fosters the application of the four metaparadigms of Hispanic culture--conquest, collectivism, familism, and personalism--for Hispanic students. The metaparadigms are described and specific examples are offered about how the Model promotes application of the metaparadigms to accomplish cultural competence for Hispanic students. Recommendations for educators are also presented.
