Surfing New Territory: Club-Drug Use and Risky Sex Among Hispanic Men Who Have Sex with Men Recruited on the Internet

The Internet presents unique and growing opportunities for conducting HIV/STD research. This article reports on the first 171 participants enrolled in an ongoing study examining use of the Internet to recruit Hispanic men who have sex with men (HMSM) living in an AIDS epicenter to participate in community-based studies. First, it descibes initial success with chatroom recruitment. Second, it compares the demographic, psychosocial, and sexual risk practices among HMSM recruited through the Internet who had used club drugs in the last 6 months and those who had not. In 2 months, 211 hours were spent recruiting in chatrooms; 735 chatroom users were engaged. Researchers used a scripted dialogue to describe the study and to invite chatroom users to visit the study’s community sites for screening and enrollment. One bundred and seventy-six men came to the community sites; 172 (98%) were eligible and completed an audio-computer assisted self-interview. In the last 6 months, 48.5% of the sample had used club drugs [defined as cocaine, crystal methamphetamines (crystal), amyl nitrites (poppers), Ecstasy, gammahydroxybutyrate (GHB), ketamine (Special K), and Viagra]. The proportion of men reporting use of each drug was: cocaine (15.8%), crystal (11.7%), poppers (31.6%), Ecstasy (14%), GHB (3.5%), Special K (3.5%), and Viagra (19.3%). In multivariate analyses, having higher number of sex partners, having higher social isolation scores, and having engaged in unprotected receptive anal intercourse were significantly associated with club-drug use. These initial findings suggest that high-risk HMSM can be successfully recruited through chatroom dialogues to participate in community-based HIV studies. The alarmingly high rates of club-drug use and risky sexual practices among HMSM underscore the need for effective HIV preventive interventions for this population.

Predictors of Sunburn Risk Among Florida Residents

CONTEXT The incidence of skin cancer, the most common type of cancer in the United States, is increasing. Sunburn is a major modifiable risk factor for skin cancer, and its prevalence among the US population is high. OBJECTIVES To identify predictors of having had a red or painful sunburn in the past 12 months among people living in Florida. METHODS Florida residents were recruited from public places and online. They were asked to complete an anonymous cross-sectional survey that assessed demographic information, dermatologic history, as well as knowledge, attitude, and behavior factors associated with sunburn. RESULTS A total of 437 participants whose data were complete for all variables were included in the multivariate analysis. In multivariate logistic regression, younger age (18-29 years) was the most significant predictor of sunburn (OR, 15.26; 95% CI, 5.97-38.98; P<.001). Other significant predictors included identifying as nonwhite (OR, 0.51; 95% CI, 0.29-0.90; P<.02), having had a full-body skin examination by a physician (OR, 1.8; 95% CI, 1.03-3.14; P<.04), reporting higher levels of skin sensitivity to the sun (OR, 4.63; 95% CI, 2.07-10.34; P<.001), having a less favorable attitude toward sun protection (OR, 0.88; 95% CI, 0.81-0.94; P<.001), having high perceived vulnerability to skin cancer (OR, 1.21; 95% CI, 1.05-1.41; P<.009), and spending less than 1 hour outside between 10 am and 4 pm on weekends (OR, 0.46; 95% CI, 0.22-0.96; P<.04). The model was statistically significant at P<.001 and correctly classified 78% of participants. CONCLUSIONS Sunburn prevention programs that osteopathic physicians can readily implement in clinical practice are urgently needed, particularly for young adult patients. This study identified 7 predictors of sunburn in Florida residents. With additional research findings, promoting attitude change toward sun protection may be a viable strategy.

Dermascope Use by Osteopathic Primary Care Physicians

CONTEXT Osteopathic physicians (ie, DOs) in primary care may play a critical role in the early detection of skin cancer. Dermoscopy improves diagnostic accuracy; however, its use among primary care DOs remains understudied. OBJECTIVES To document dermascope use among DOs in primary care, to examine physician and practice characteristics associated with having used and having heard of a dermascope, and to examine the barriers to dermascope use. METHODS Osteopathic physicians were recruited to complete an anonymous survey assessing demographic factors, physician and practice characteristics, confidence in differentiating skin lesions, knowledge and dermascope use, and barriers to dermascope use. Bivariate analyses were conducted, and the significant factors were entered into 2 separate logistic regressions. RESULTS A total of 768 participants were included in the study. Four hundred ten (54%) had heard of a dermascope, and 123 (15%) had used one. The statistically significant multivariate predictors for having used a dermascope (model 1) were graduating from medical school after 1989 and having greater confidence in differentiating skin lesions (OR, 2.2; 95% CI, 1.66-2.79). Those who graduated after 2009 were 9.5 times more likely and those graduating between 2000 and 2009 were 4.3 times more likely to have used a dermascope than those graduating before 1990 (95% CI, 4.29-20.90 and 95% CI, 2.04-9.23, respectively). Ever having heard of a dermascope (model 2) was associated with being female (OR, 1.4; 95% CI, 1.02-1.87); practicing in a group (OR, 1.6; 95% CI, 1.05-2.36), academic (OR, 2.2; 95% CI, 1.26-3.86), or community center (OR, 2.2; 95% CI, 1.20-4.00); and having greater confidence in differentiating skin lesions (OR, 1.3; 95% CI, 1.15-1.55). Both models were statistically significant and correctly classified 605 (84.1%) (model 1) and 444 (58.4%) participants (model 2). CONCLUSION Dermascope use could help primary care DOs improve their diagnostic accuracy for skin cancer and reduce unnecessary referrals to specialists. Efforts to disseminate knowledge about the benefits of using a dermascope to primary care DOs are needed.

Examining the factors associated with past and present dermoscopy use among family physicians

Introduction Family physicians (FPs) play a critical role in the early detection of skin cancers. Dermoscopy can improve diagnostic accuracy but its use by FPs in the United States (US) remains understudied. Objectives To examine dermoscopy use, factors associated with ever having used (Model 1) and currently using the dermascope (Model 2), and barriers. Methods We recruited 705 practicing FPs in-person at conferences and on-line to complete an anonymous, 46 item survey measuring: demographic factors, physician and practice characteristics; confidence in differentiating skin lesions; knowledge and use of dermoscopy; intentions to use; and barriers to use. We conducted bivariate analysis for each outcome and entered the significant predictors into two logistic regressions. Results Almost 20% had ever used a dermascope and 8.3% were currently using it. Ever having used a dermascope was associated with being 39 years of age or younger, practicing in academia or community centers, and having higher confidence differentiating skin lesions. Current use was associated with seeing more than 400 patients per month and being 60 years-of-age or older. Conclusion Use of dermoscopy by FPs is low. This study is an initial step in understanding its use among US FPs.

Use of and intentions to use dermoscopy among physicians in the United States

Background Dermatologists routinely use dermoscopy to improve diagnostic accuracy of skin cancers. Much less is known about its use among other physicians who routinely examine the skin, such as family physicians, internists and plastic surgeons. Objectives To document the use of dermoscopy in a sample of US physicians and to examine physician and practice characteristics associated with ever having used a dermascope and having some intentions to incorporate dermoscopy into clinical practice during the next 12 months. Methods From September 2015 to February 2016, we recruited 1,466 practicing physicians in person and online to complete an anonymous survey that assessed: demographic factors; physicians and practice characteristics; confidence differentiating skin lesions; knowledge and use of dermoscopy; and intentions and barriers to use dermoscopy. We conducted bivariate analysis to examine the relationship between key factors and the outcomes and entered the significant predictors into two separate logistic regressions. Results Fifteen percent of participants had ever used a dermascope and 6% were currently using it. Factors significantly associated with ever having used a dermascope (Model 1) and having intentions to use (Model 2) at the multivariate level were: recent graduation from medical school (strongest predictor in both models), identifying as a family physician, seeing a higher number of patients with skin cancer and having a higher level of confidence differentiating skin lesions. Both models were highly significant. Conclusion Use of dermoscopy was low. Promotional efforts to increase dermoscopy use in the US are needed.
