Mixed Reality Interaction and Presentation Techniques for Medical Visualisations.

Mixed, Augmented and Virtual reality technologies are burgeoning with new applications and use cases appearing rapidly. This chapter provides a brief overview of the fundamental display presentation methods; head-worn, hand-held and projector-based displays. We present a summary of visualisation methods that employ these technologies in the medical domain with a diverse range of examples presented including diagnostic and exploration, intervention and clinical, interaction and gestures, and education.

Characteristics and current clinical practices of opioid treatment programs in the United States.

BACKGROUND: Given rising rates of opioid use disorder (OUD) and related consequences, opioid treatment programs (OTPs) can play a pivotal role in the U.S. opioid crisis. There is a paucity of recent research to guide how best to leverage OTPs in the opioid response. METHODS: We conducted a national survey of U.S. OTPs using a 46-question electronic survey instrument covering three domains: 1) OTP characteristics; 2) services offered; and 3) current clinical practices. Descriptive statistics and multivariable logistic regression examined variables in these domains. RESULTS: Among responding OTPs, 32.4% reported using all three medications for OUD treatment; 95.8% used methadone, 61.8% used buprenorphine, and 43.9% used naltrexone. The mean (SD) number of patients currently receiving methadone was 383 (20.4), buprenorphine 51 (7.0), extended-release naltrexone 6 (1.0). Viral hepatitis testing was provided by 60.9% of OTPs, 15.3% provided hepatitis B vaccination, 14.9% provided hepatitis A vaccination, and 12.6% provided medication treatment for hepatitis C virus infection. HIV testing was provided by 60.7% of OTPs, 9.5% provided pre-exposure prophylaxis, and 8.4% provided medication treatment for HIV. OTP characteristics associated with using all three forms of medications for OUD included: providing medication for alcohol use disorder (aOR = 5.24, 95% CI:2.99-9.16), providing telemedicine services (aOR = 3.82, 95% CI:2.14-6.84), and directly providing naloxone to patients (aOR = 2.57, 95% CI:1.53-4.29). Multiple barriers to providing buprenorphine and extended-release naltrexone were identified. CONCLUSIONS: Efforts are needed to increase availability of all medications approved to treat OUD in OTPs, integrate infectious disease-related services, and expand the reach of OTPs in the U.S.

Are teens "post-gay"? Contemporary adolescents' sexual identity labels.

Recent reports suggest that historically typical sexual identity labels-"gay," "lesbian" and "bisexual"-have lost meaning and relevance for contemporary adolescents. Yet there is little empirical evidence that contemporary teenagers are "post-gay." In this brief study we investigate youths' sexual identity labels. The Preventing School Harassment survey included 2,560 California secondary school students administered over 3 years: 2003-2005. We examined adolescents' responses to a closed-ended survey question that asked for self-reports of sexual identity, including an option to write-in a response; we content analyzed the write-in responses. Results suggest that historically typical sexual identity labels are endorsed by the majority (71%) of non-heterosexual youth. Some non-heterosexual youth report that they are "questioning" (13%) their sexual identities or that they are "queer" (5%); a small proportion (9%) provided alternative labels that describe ambivalence or resistance to sexual identity labels, or fluidity in sexual identities. Our results show that lesbian, gay, and bisexual identities remain relevant for contemporary adolescents.
