Racial and ethnic underrepresentation in dermatology clinical trials.

BACKGROUND: Including participants of diverse racial and ethnic populations in clinical trials is important to reduce disparities and promote health care equity. OBJECTIVE: To evaluate racial and ethnic representation in dermatology clinical trials. METHODS: Participant data from dermatology trials completed in the United States from 2017 to 2021 from ClinicalTrials.gov were compared to census data to determine if minority groups were represented at rates that reflect population demographics. Participation was compared with prevalence rates for the most underrepresented racial group. RESULTS: Of 246 trials that met inclusion criteria, 87.4% (215) reported racial data. Compared to census data, Black/African American, American Indian/Alaskan Native, and 2 or more races were underrepresented. Hispanic or Latinos were an underrepresented ethnic group. LIMITATIONS: The search was limited to ClinicalTrials.gov registered studies that fell within search parameters. Race reporting methods were not specified. Detailed analysis was only performed for the most underrepresented racial group. CONCLUSION: Certain minority groups were underrepresented in dermatology trials. Black/African Americans were most underrepresented and underrepresented even when accounting for prevalence rates. Trial representation that accurately reflects population demographics and subgroup prevalence rates can help reduce health inequity, improve clinical understanding, and enhance treatment access for the growing diverse population.

Minimally Invasive Facial Cosmetic Procedures for the Millennial Aesthetic Patient.

Millennials, defined as the generation of individuals born between 1981 and 1996, have emerged as one of the leading patient demographics seeking minimally invasive cosmetic procedures. Worldwide, millennials are more likely to consider preventative treatments compared to any other age-group. The three most popular minimally invasive facial procedures in this demographic include botulinum toxin, dermal fillers (eg, hyaluronic acid, calcium hydroxylapatite, facial fat-fillers), and microdermabrasion. Given their impact on the expanding aesthetic medicine market and their favorable disposition towards cosmetic procedures, it is necessary for dermatologists and cosmetic providers to understand their motivations and perspectives. While some research studies have elicited the opinions of millennials on social issues, education, and technology, there is a paucity of literature on millennials' impressions, opinions, and perceptions of aesthetic procedures. As a generation that has been reshaping the culture of healthcare delivery and encouraging the innovation of products and procedures with their unique values and perspectives, accounting for their beliefs and fostering a better understanding of their experiences will promote an elevation in the quality of their care.

A Systematic Review of Light Emitting Diode (LED) Phototherapy for Treatment of Psoriasis: An Emerging Therapeutic Modality.

Background: Psoriasis is a chronic, inflammatory skin condition. The economic burden of psoriasis is approximately $35.2 billion in the United States per year, and treatment costs are increasing at a higher rate than general inflation. Light emitting diode (LED) phototherapy may represent a cost-effective, efficacious, safe, and portable treatment modality for psoriasis.

Objective: The goal of our manuscript is to review the published literature and provide evidence-based recommendations on LED phototherapy for the treatment of psoriasis.

Methods & Materials: A search of the databases Pubmed, EMBASE, Web of Science, and CINAHL was performed on April 5, 2016. Key search terms were related to psoriasis and LED-based therapies.

Results: A total of 7,793 articles were generated from the initial search and 5 original articles met inclusion criteria for our review. Grade of recommendation: B for LED-blue light. Grade of recommendation: C for LED-ultraviolet B, LED-red light, and combination LED-near-infrared and LED-red light.

Conclusion: We envision further characterizing the effects of LED phototherapy to treat psoriasis in patients may increase adoption of LED-based modalities and provide clinicians and patients with new therapeutic options that balance safety, efficacy, and cost.

A systematic review of low-level light therapy for treatment of diabetic foot ulcer.

Diabetes mellitus (DM) is a significant international health concern affecting more than 387 million individuals. A diabetic person has a 25% lifetime risk of developing a diabetic foot ulcer (DFU), leading to limb amputation in up to one in six DFU patients. Low-level light therapy (LLLT) uses low-power lasers or light-emitting diodes to alter cellular function and molecular pathways, and may be a promising treatment for DFU. The goal of this systematic review is to examine whether the clinical use of LLLT is effective in the healing of DFU at 12 and 20 weeks in comparison with the standard of care, and to provide evidence-based recommendation and future clinical guidelines for the treatment of DFU using LLLT. On September 30, 2015, we searched PubMed, EMBASE, CINAHL, and Web of Science databases using the following terms: "diabetic foot" AND "low level light therapy," OR "light emitting diode," OR "phototherapy," OR "laser." The relevant articles that met the following criteria were selected for inclusion: randomized control trials (RCTs) that investigated the use of LLLT for treatment of DFU. Four RCTs involving 131 participants were suitable for inclusion based upon our criteria. The clinical trials used sham irriadiation, low dose, or nontherapeutic LLLT as placebo or control in comparison to LLLT. The endpoints included ulcer size and time to complete healing with follow-up ranging from 2 to 16 weeks. Each article was assigned a level of evidence (LOE) and graded according to the Oxford Center for Evidence-based Medicine Levels of Evidence Grades of Recommendation criteria. Limitations of reviewed RCTs include a small sample size (N < 100), unclear allocation concealment, lack of screening phase to exclude rapid healers, unclear inclusion/exclusion criteria, short (<30 days) follow-up period, and unclear treatment settings (wavelength and treatment time). However, all reviewed RCTs demonstrated therapeutic outcomes with no adverse events using LLLT for treatment of DFU. This systematic review reports that LLLT has significant potential to become a portable, minimally invasive, easy-to-use, and cost effective modality for treatment of DFU. To enthusiastically recommend LLLT for treatment of DFU, additional studies with comparable laser parameters, screening period to exclude rapid healers, larger sample sizes and longer follow-up periods are required. We envision future stringent RCTs may validate LLLT for treatment of DFU. Systematic review registration number: PROSPERO CRD42015029825.

A systematic review of filler agents for aesthetic treatment of HIV facial lipoatrophy (FLA).

HIV facial lipoatrophy (FLA) is characterized by facial volume loss. HIV FLA affects the facial contours of the cheeks, temples, and orbits, and is associated with social stigma. Although new highly active antiretroviral therapy medications are associated with less severe FLA, the prevalence of HIV FLA among treated individuals exceeds 50%. The goal of our systematic review is to examine published clinical studies involving the use of filler agents for aesthetic treatment of HIV FLA and to provide evidence-based recommendations based on published efficacy and safety data. A systematic review of the published literature was performed on July 1, 2015, on filler agents for aesthetic treatment of HIV FLA. Based on published studies, poly-L-lactic acid is the only filler agent with grade of recommendation: B. Other reviewed filler agents received grade of recommendation: C or D. Poly-L-lactic acid may be best for treatment over temples and cheeks, whereas calcium hydroxylapatite, with a Food and Drug Administration indication of subdermal implantation, may be best used deeply over bone for focal enhancement. Additional long-term randomized controlled trials are necessary to elucidate the advantages and disadvantages of fillers that have different biophysical properties, in conjunction with cost-effectiveness analysis, for treatment of HIV FLA.
