Prevalence and correlates of substance use and associations with HIV-related outcomes among trans women in the San Francisco Bay Area.

BACKGROUND: Trans women face tremendous social inequities as well as disproportionate rates of HIV and substance use, yet disaggregated substance use data specific to trans women remain limited. METHODS: We conducted a secondary analysis of baseline data from the Trans*National Study (2016-2017) surveying trans women in the San Francisco Bay Area (n = 629). Multivariable logistic regression was used to analyze socio-demographic and environmental correlates of substance use, and bivariate associations between substance use and HIV-associated outcomes are presented alongside prevalence data. RESULTS: Over half (52.9%) reported using substances in the prior year, most frequently marijuana, methamphetamine, and crack/cocaine. Those with unmet gender-affirming health care needs, lack of insurance, or a history of experiencing racial violence, transphobic violence, adult housing instability, or extreme poverty had higher odds of substance use. Sex work and condomless anal sex were also independently associated with substance use. CONCLUSIONS: Among this sample of trans women, substance use and substance use concurrent with sex were highly prevalent, and associated with a number of socioeconomic and health care needs. These findings corroborate the need for holistic and intersectional efforts to reduce substance use and HIV risk.

Contemplative Practices Behavior Is Positively Associated with Well-Being in Three Global Multi-Regional Stanford WELL for Life Cohorts.

Positive associations between well-being and a single contemplative practice (e.g., mindfulness meditation) are well documented, yet prior work may have underestimated the strength of the association by omitting consideration of multiple and/or alternative contemplative practices. Moreover, little is known about how contemplative practice behavior (CPB) impacts different dimensions of well-being. This study investigates the relationship of CPB, consisting of four discrete practices (embodied somatic-observing, non-reactive mindfulness, self-compassion, and compassion for others), with multiple dimensions of well-being. As with other canonical lifestyle behaviors, multiple contemplative practices can be integrated into one's daily routine. Thus, it is critical to holistically consider these behaviors, extending them beyond a simple uni-dimensional measure (e.g., daily mindfulness meditation practice). We developed an integrative measure of four types of contemplative practice and found it to be significantly associated with a multi-dimensional measure of well-being. Importantly, our findings were from three large global multi-regional cohorts and compared against better-understood lifestyle behaviors (physical activity). Data were drawn from California/San Francisco Bay Area, (n = 6442), Hangzhou City (n = 10,268), and New Taipei City (n = 3033). In all three cohorts, we found statistically significant (p < 0.05) positive associations between CPB and well-being, both overall and with all of the constituent domains of well-being, comparable to or stronger than the relationship with physical activity across most well-being outcomes. These findings provide robust and cross-cultural evidence for a positive association between CPB and well-being, illuminate dimensions of well-being that could be most influenced by CPB, and suggest CPB may be useful to include as part of fundamental lifestyle recommendations for health and well-being.

Ancient and modern genomics of the Ohlone Indigenous population of California.

SignificanceCalifornia supports a high cultural and linguistic diversity of Indigenous peoples. In a partnership of researchers with the Muwekma Ohlone tribe, we studied genomes of eight present-day tribal members and 12 ancient individuals from two archaeological sites in the San Francisco Bay Area, spanning ∼2,000 y. We find that compared to genomes of Indigenous individuals from throughout the Americas, the 12 ancient individuals are most genetically similar to ancient individuals from Southern California, and that despite spanning a large time period, they share distinctive ancestry. This ancestry is also shared with present-day tribal members, providing evidence of genetic continuity between past and present Indigenous individuals in the region, in contrast to some popular reconstructions based on archaeological and linguistic information.

Improving Diversity in Pediatric Residency Selection: Using an Equity Framework to Implement Holistic Review.

BACKGROUND: Many programs struggle to recruit, select, and match a diverse class of residents, and the most effective strategies for holistic review of applications to enhance diversity are not clear. OBJECTIVE: We determined if holistic pediatric residency application review guided by frameworks that assess for bias along structural, interpersonal, and individual levels would increase the number of matched residents from racial and ethnic groups that are underrepresented in medicine (UiM). METHODS: Between 2017 and 2020, University of California San Francisco Pediatrics Department identified structural, interpersonal, and individual biases in existing selection processes and developed mitigation strategies in each area. Interventions included creating a shared mental model of desirable qualities in residents, employing a new scoring rubric, intentional inclusion of UiM faculty and trainees in the selection process, and requiring anti-bias training for everyone involved with recruitment and selection. RESULTS: Since implementing these changes, the percentage of entering interns who self-identify as UIM increased from 11% in 2015 to 45% (OR 6.8, P = .008) in 2019 and to 35% (OR 4.6, P = .035) in 2020. CONCLUSIONS: Using an equity framework to guide implementation of a pediatric residency program's holistic review of applications increased the numbers of matched UiM residents over a 3-year period.

Comparison of Fruit and Vegetable Intake Among Urban Low-Income US Adults Receiving a Produce Voucher in 2 Cities.

Importance: Fruit and vegetable vouchers have been implemented by cities and counties across the US to increase fruit and vegetable intake and thereby improve overall nutritional quality. Objective: To determine whether and why use of fruit and vegetable vouchers are associated with varied nutritional intake across different populations and environments. Design, Setting, and Participants: In a population-based pre-post cohort study of 671 adult participants with low income before and during (6 months after initiation) participation in a 6-month program, fruit and vegetable vouchers were distributed for redemption at local San Francisco and Los Angeles neighborhood grocery and corner stores between 2017 and 2019. A transportability analysis was performed to identify factors that may explain variation in voucher use between cities. Exposure: Receipt of $20 per month in produce vouchers for 6 months from 2017 to 2019. Main Outcomes and Measures: Change in total fruits and vegetables (as defined by the US Department of Agriculture) consumed per person per day (change in cup-equivalents between month 6 and month 0). Results: A total of 671 adults (median age, 54.9 years [interquartile range, 45.0-65.0 years]; 61.7% female; 30.9% Black; 19.7% Hispanic) were enrolled. An increase in fruit and vegetable intake of 0.22 cup-equivalents per day overall (95% CI, 0.14-0.31 cup-equivalents; P < .001) was observed. However, the observed increase was larger in Los Angeles compared with San Francisco (0.64 cup-equivalents per day; 95% CI, 0.41-0.88 cup-equivalents vs 0.10 cup-equivalents per day; 95% CI, 0.01-0.19 cup-equivalents). When the concurrently sampled San Francisco group (n = 157) was weighted in transportability analysis to demographically match the Los Angeles group (n = 155) in observed covariates, the weighted San Francisco group had an estimated increase of 0.53 fruit and vegetable cup-equivalents per day (95% CI, 0.27- 0.79 cup-equivalents, P = .03), with income being the variable needed to allow the 95% confidence intervals to overlap between the weighted San Francisco and unweighted Los Angeles populations. Conclusions and Relevance: In this study, the use of fruit and vegetable vouchers appeared to be associated with greater benefit among those with lower incomes, suggesting that further investigation of flat-rate rather than income-scaled benefits is warranted.

Unmet Health and Social Welfare Needs of Women Who Inject Drugs in San Francisco.

We characterize social welfare and health care needs of women who inject drugs in a community-based survey in San Francisco. A total of 139 women were enrolled; 74.8% were homeless, and 67.6% earned below poverty level. Indicators of health care and prevention program access included: 95.7% with health insurance, 90.6% used a needle exchange program, and 58.2% tested for HIV two or more times. However, only 8.6% received HPV vaccination and there was unmet contraception need for 79.0% of women. Only 28.7% of those testing positive for HCV infection had received treatment. Physical and sexual violence in the last year were common (41.0% and 18.0%, respectively). Women who inject drugs would benefit from integrated health and social services including addressing interpersonal violence, sexual and reproductive health, and HIV and HCV prevention needs. Women-only needle exchange programs and safe injection sites may be effective delivery points for these services.

Treating tobacco dependence to aid re-employment among job-seekers: A randomized controlled trial.

INTRODUCTION: U.S. reductions in smoking have not been experienced equally. Smoking prevalence is greater among persons of lower education, lower income, and unemployed. We evaluated whether a cessation intervention for job-seekers would result in significantly fewer cigarettes smoked per day and a greater likelihood of tobacco abstinence and re-employment, compared to the control condition at 6-months follow-up. METHODS: Unemployed, job-seekers who smoked daily were recruited from five employment development departments in the San Francisco Bay Area, October 2015 to February 2018. Intention to quit smoking was not required. Participants were randomized to a brief motivationally-tailored, computer-assisted counseling intervention or referred to a toll-free quitline. Midstudy, 8-weeks of combination nicotine replacement was added to the intervention. Expired carbon monoxide and cotinine testing verified abstinence. Data were analyzed fall 2019. RESULTS: Participants (N = 360; 70% men; 43% African American, 27% non-Hispanic Caucasian; 19% unhoused) averaged 12 cigarettes/day (SD = 6), 67% smoked within 30 min of wakening; 27% were in preparation stage to quit. During the 6-month study period, intervention participants were more likely to make a quit attempt (71% vs. 58%, p = .021) and reported significantly greater reduction in cigarettes/day than control participants (median reduction: 6.9 vs. 5.0, p = .038); however, bioconfirmed abstinence (3%) and re-employment (36%) did not differ by treatment group. CONCLUSIONS: In a diverse sample with economic hardships, quit attempts and smoking reduction were greater in the intervention group; however, few achieved abstinence, and neither abstinence nor re-employment differed by condition. A priority group, further research is needed on smoking and re-employment.

We Are All Women: Barriers and Facilitators to Inclusion of Transgender Women in HIV Treatment and Support Services Designed for Cisgender Women.

Transgender women share more in common with cisgender women, with respect to sociocultural context and factors influencing HIV risk and outcomes, than they do with "men who have sex with men", a behavioral risk category in which they often are included. However, it is not yet clear whether both transgender and cisgender women would find integrated, all-women HIV programs and services desirable and beneficial. We Are All Women was a qualitative study conducted in the San Francisco Bay Area from April 2016 to January 2017, using a conceptual framework based on gender affirmation and trauma-informed care, to explore barriers and facilitators to inclusion of transgender women in HIV treatment and support services traditionally focused on cisgender women. Thirty-eight women (10 trans, 25 cis, and 3 "other" gender) participated in six semistructured, facilitated focus groups. In addition, five HIV care providers participated in semistructured, in-depth interviews. Both trans and cis women identified the desire for gender affirmation, a feeling of safety (specifically space without men), and potential community building within a care and healing context as powerful facilitators of an inclusive all-women care environment. At the same time, they recognized that tensions do exist between idealized visions of such an environment, deep-seated sentiments and behaviors among some cis women toward trans women, and the practical realities of creating the optimal spaces for all women. Opportunities for dialog between trans and cis women to mitigate gender-associated phobias and misperceptions are a valuable first step in creating HIV care environments that serve all women.

Rapid Utilization of Telehealth in a Comprehensive Cancer Center as a Response to COVID-19: Cross-Sectional Analysis.

BACKGROUND: The emergence of the coronavirus disease (COVID-19) pandemic in March 2020 created unprecedented challenges in the provision of scheduled ambulatory cancer care. As a result, there has been a renewed focus on video-based telehealth consultations as a means to continue ambulatory care. OBJECTIVE: The aim of this study is to analyze the change in video visit volume at the University of California, San Francisco (UCSF) Comprehensive Cancer Center in response to COVID-19 and compare patient demographics and appointment data from January 1, 2020, and in the 11 weeks after the transition to video visits. METHODS: Patient demographics and appointment data (dates, visit types, and departments) were extracted from the electronic health record reporting database. Video visits were performed using a HIPAA (Health Insurance Portability and Accountability Act)-compliant video conferencing platform with a pre-existing workflow. RESULTS: In 17 departments and divisions at the UCSF Cancer Center, 2284 video visits were performed in the 11 weeks before COVID-19 changes were implemented (mean 208, SD 75 per week) and 12,946 video visits were performed in the 11-week post-COVID-19 period (mean 1177, SD 120 per week). The proportion of video visits increased from 7%-18% to 54%-72%, between the pre- and post-COVID-19 periods without any disparity based on race/ethnicity, primary language, or payor. CONCLUSIONS: In a remarkably brief period of time, we rapidly scaled the utilization of telehealth in response to COVID-19 and maintained access to complex oncologic care at a time of social distancing.

Missed opportunities to prevent HIV infections among pre-exposure prophylaxis users: a population-based mixed methods study, San Francisco, United States.

INTRODUCTION: Pre-exposure prophylaxis (PrEP) is highly effective, although PrEP adherence and persistence has been variable during real world implementation. Little is known about missed opportunities to enhance PrEP adherence among individuals who later HIV seroconverted after using PrEP. The goal of this analysis was to identify all HIV infections among individuals who had accessed PrEP in an integrated health system in San Francisco, and to identify potentially intervenable factors that could have prevented HIV infection through in-depth interviews with people who HIV seroconverted after using PrEP. METHODS: We identified individuals who initiated PrEP in an integrated safety-net public health system and performed in-depth chart review to determine person-time on and after stopping PrEP over six years. We identified all PrEP seroconversions using the Centers for Disease Control and Prevention's Enhanced HIV/AIDS Reporting System and then calculated HIV incidence while using PrEP and during gaps in use. We then performed in-depth interviews with those who seroconverted. RESULTS: Overall, 986 initiated PrEP across the San Francisco Department of Public Health from July 2012 to November 2018. Data were gathered from 895 person-years on PrEP and 953 after stopping PrEP. The HIV incidence was 7.5-fold higher after stopping PrEP compared to while on PrEP (95% CI 1 to 336). Of the eight individuals who HIV seroconverted; only one was taking PrEP at the time of seroconversion but was using on-demand PrEP inconsistently. All eight agreed to qualitative interviews. Major barriers to PrEP persistence included substance use, mental health and housing loss; difficulty accessing PrEP due to cost, insurance, and the cost and time of medical visits; difficulty weighing PrEP's benefit versus self-perceived risk; and entering a primary partnership. The individual who developed HIV using on-demand PrEP reported confusion about the dosing regimen and which sexual encounters required accompanying PrEP dosing. CONCLUSIONS: HIV incidence during gaps in PrEP use was nearly eight-fold higher than while on PrEP in this large cohort in San Francisco. Many individuals who stop PrEP remain at risk of HIV, and participants reported that proactive outreach could potentially have prevented HIV infections. Individuals using non-daily PrEP may require additional education and support in the United States.

Quarterly screening optimizes detection of sexually transmitted infections when prescribing HIV preexposure prophylaxis.

OBJECTIVE: The optimal screening frequency of sexually transmitted infections (STIs) for MSM and transgender women (TGW) on HIV pre-exposure prophylaxis (PrEP) is unclear, with present guidelines recommending screening every 3-6 months. We aimed to determine the number of STIs for which treatment would have been delayed without quarterly screening. DESIGN: The US PrEP Demonstration Project was a prospective, open-label cohort study that evaluated PrEP delivery in STI clinics in San Francisco and Miami, and a community health center in Washington, DC. In all, 557 HIV-uninfected MSM and TGW were offered up to 48 weeks of PrEP and screened quarterly for STIs. METHODS: The proportion of gonorrhea, chlamydia, and syphilis infections for which treatment would have been delayed had screening been conducted every 6 versus every 3 months was determined by taking the number of asymptomatic STIs at weeks 12 and 36 divided by the total number of infections during the study follow-up period for each STI. RESULTS: Among the participants, 50.9% had an STI during follow-up. If screening had been conducted only semiannually or based on symptoms, identification of 34.3% of gonorrhea, 40.0% of chlamydia, and 20.4% of syphilis infections would have been delayed by up to 3 months. The vast majority of participants (89.2%) with asymptomatic STIs reported condomless anal sex and had a mean of 8.1 partners between quarterly visits. CONCLUSIONS: Quarterly STI screening among MSM on PrEP could prevent a substantial number of partners from being exposed to asymptomatic STIs, and decrease transmission.

The impact of transitioning from availability of outside records within electronic health records to integration of local and outside records within electronic health records.

OBJECTIVE: While there has been a substantial increase in health information exchange, levels of outside records use by frontline providers are low. We assessed whether integration between outside data and local data results in increased viewing of outside records, overall and by encounter, provider, and patient type. MATERIALS AND METHODS: Using data from UCSF Health, we measured change in outside record views after integrating the list of local (UCSF) and outside (other health systems on Epic [Epic Systems, Verona, WI]) encounters on the Chart Review tab. Previously, providers only viewed records from outside encounters on a separate tab. We used an interrupted time series design (with outside record viewing event counts aggregated to the week level) to measure changes in the level and trend over a 1-year period. RESULTS: There was a large increase in the level of outside record views of 22 920 per week (P < .001). The change in trend went from a weekly increase of 116 (P < .05) to a decrease of 402 (P = .08), reflecting a small effect decay. There were increases in the level of views for all provider and encounter types: attendings (n = 3675), residents (n = 3277), and nurses (n = 914); and inpatient (n = 1676), emergency (n = 487), and outpatient (n = 7228) (P < .001 for all). Results persisted when adjusted for total encounter volume. DISCUSSION: While outside records were readily available before the encounter integration, the simple step of clicking on a separate tab appears to have depressed use. CONCLUSIONS: User interface designs that comingle local and outside data result in higher levels of viewing and should be more broadly pursued.

"Chasing the pain relief, not the high": Experiences managing pain after opioid reductions among patients with HIV and a history of substance use.

BACKGROUND: Opioid overdose mortality continues to increase in the United States despite significant investments to reverse the epidemic. The national response to-date has focused primarily on reducing opioid prescribing, yet reductions in prescribing have been associated with patients reporting uncontrolled pain, psychological distress, and transition to illicit substances. The aim of this study is to qualitatively explore chronic pain management experiences among PLWH with a history of illicit substance use after long-term opioid therapy reductions or discontinuations. METHODS: We analyzed 18 interviews, stopping upon reaching thematic saturation, with HIV-positive participants with a history of substance use who were enrolled in a longitudinal cohort study to assess the impact of prescribing changes among patients with chronic pain. Participants in this nested qualitative study had been reduced/discontinued from opioid pain relievers (OPRs) within the 12 months prior to interview. Interviews were audio-recorded and transcribed verbatim. Two analysts coded all interviews, interrater reliability was measured, and coding discrepancies discussed. The study took place in San Francisco, California in 2018. RESULTS: Eleven participants were male with a mean age of 55; 8 were African American and 8 were White. All participants were HIV-positive, actively engaged in primary care, and had a lifetime history of illicit substance use. Twelve reported using illicit substances within the past year, including non-prescription opioids/heroin (10), and stimulant use (10). After being reduced/discontinued from their long-term opioid therapy, patients reported developing complex multimodal pain management systems that often included both nonpharmacological approaches and illicit substance use. Participants encountered a range of barriers to nonpharmacological therapies including issues related to accessibility and availability. Participants often reported attempts to replicate their prior OPR prescription by seeking out the same medication and dose from illicit sources and reported transitioning to heroin after exhausting other options. CONCLUSION: After being reduced/discontinued from OPRs, HIV-positive patients with a history of substance use reported experimenting with a range of pain management modalities including nonpharmacological therapies and illicit substance use to manage symptoms of opioid withdrawal and pain. Providers should consider that any change to a patients' long-term opioid therapy may result in experimentation with pain management outside of the medical setting and may want to employ patient-centered, holistic approaches when managing patients' opioid prescriptions and chronic pain.

Knowledge and self-efficacy for caring for breast and colon cancer survivors among safety net primary care providers.

BACKGROUND: Primary care providers (PCPs) are critical to the provision of comprehensive care for cancer survivors, yet there is very little data on the practices and quality of survivorship care occurring in safety net primary care settings. This study aimed to assess the knowledge and attitudes of PCPs and preferences for care models for breast and colon cancer survivors in a safety net health network. METHODS: A modified National Cancer Institute Survey of Physician Attitudes Regarding the Care of Cancer Survivors was sent electronically to 220 PCPs in 12 primary care clinics in the San Francisco Health Network affiliated with Zuckerberg San Francisco General Hospital and Trauma Center. RESULTS: The response rate was 50% (110/220). About half of PCPs strongly/somewhat agreed (vs. strongly/somewhat disagreed) that PCPs have the knowledge needed to provide follow-up care related to breast (50%) and colon cancer (54%). Most providers (93%) correctly reported recommended frequency of mammography, however, frequency of blood tests and other imaging surveillance were not as well recognized for breast or colon cancer. Recognition of long-term side effects of chemotherapy drugs ranged from 12% for oxaliplatin to 44% for doxorubicin. Only 33% of providers reported receiving any survivorship training. The most preferred model for survivorship care was shared care model (40%). CONCLUSIONS: Safety net PCPs prefer a shared care model for care of cancer survivors but are limited by lack of training, poor communication, and poor delineation of roles. Patient-centered survivorship care can be improved through effective oncologist-PCP-patient partnerships and coordination.

Toward Creating Equity in Awards Received During Medical School: Strategic Changes at One Institution.

Membership in the Alpha Omega Alpha Honor Medical Society (AΩA) is a widely recognized achievement valued by residency selection committees and employers. Yet research has shown selection favors students from racial/ethnic groups not underrepresented in medicine (not-UIM). The authors describe efforts to create equity in AΩA selection at the University of California, San Francisco, School of Medicine, through implementation of a holistic selection process, starting with the class of 2017, and present outcomes.Informed by the definition of holistic review, medical school leaders applied strategic changes grounded in evidence on inclusion, mitigating bias, and increasing opportunity throughout the AΩA selection process. These addressed increasing selection committee diversity, revising selection criteria and training committee members to review applications using a new instrument, broadening student eligibility and inviting applications, reviewing blinded applications, and making final selection decisions based on review and discussion of a rank-ordered list of students that equally weighted academic achievement and professional contributions.The authors compared AΩA eligibility and selection outcomes for 3 classes (2014-2016) during clerkship metric-driven selection, which prioritized academic achievement, and 3 classes (2017-2019) during holistic selection. During clerkship metric-driven selection, not-UIM students were 4 times more likely than UIM students to be eligible for AΩA (P = .001) and 3 times more likely to be selected (P = .001). During holistic selection, not-UIM students were 2 times more likely than UIM students to be eligible for AΩA (P = .001); not-UIM and UIM students were similarly likely to be selected (odds ratio = .7, P = .12)This new holistic selection process created equity in representation of UIM students among students selected for AΩA. Centered on equity pedagogy, which advocates dismantling structures that create inequity, this holistic selection process has implications for creating equity in awards selection during medical education.

Resolving selenium exposure risk: Spatial, temporal, and tissue-specific variability of an endemic fish in a large, dynamic estuary.

Estuaries provide critical habitat for a vast array of fish and wildlife but are also a nexus for core economic activities that mobilize and concentrate contaminants that can threaten aquatic species. Selenium (Se), an essential element and potent reproductive toxin, is enriched in parts of the San Francisco Estuary (SFE) to levels known to cause toxicity, yet the risk of Se to species that inhabit the SFE is not well understood. We quantified Se concentrations in muscle, liver and ovary of the demersal cyprinid Sacramento Splittail from six regions in the SFE at three time points to evaluate Se exposure risk. Selenium levels exceeded proposed EPA criteria in ovary and thresholds of concern for liver in 15% and 20%, respectively, of fish collected in the fall of 2010, preceding the discovery of juvenile Splittail displaying a high incidence (>40%) of spinal deformities characteristic of Se toxicity, and again in 2011. No exceedances were detected in muscle tissue. Selenium concentrations varied significantly among regions for muscle (F5,113 = 20.49, p < 0.0001), liver (F5,113 = 28.4, p < 0.0001) and ovary (F5,112 = 19.3, p < 0.0001) but did not vary between the wet and dry years, nor were they influenced by foraging trophic level or prey selection. Foraging location along the salinity gradient, defined by δ34S values, explained regional Se exposures in Splittail. Relationships between tissues varied among regions for muscle and liver and muscle and ovary, but a single global relationship could be defined for ovary and liver Se concentrations. Our results suggest that the proposed EPA Se criteria for muscle tissue in Splittail may be under-protective as it would not have predicted exceedances in liver or ovary tissue and that the relationship between muscle tissue and ovary and liver may be Se concentration and seasonal dependent.

Evoked K-complexes and altered interaction between the central and autonomic nervous systems during sleep in alcohol use disorder.

There is evidence for impairment in both central nervous system (CNS) and autonomic nervous system (ANS) function with prolonged alcohol use. While these impairments persist into abstinence, partial recovery of function has been demonstrated in both systems during sleep. To investigate potential ANS dysfunction associated with cortical CNS responses (impairment in CNS-ANS coupling), we assessed phasic heart rate (HR) fluctuation associated with tones that did and those that did not elicit a K-complex (KC) during stable N2 non-rapid eye movement (NREM) sleep in a group of 16 recently abstinent alcohol use disorder (AUD) patients (41.6 ± 8.5 years) and a group of 13 sex- and age-matched control participants (46.6 ± 9.3 years). Electroencephalogram (EEG) and electrocardiogram (ECG) data were recorded throughout the night. Alcohol consumption questionnaires were also administered to the AUD patients. AUD patients had elevated HR compared to controls at baseline prior to tone presentation. The HR fluctuation associated with KCs elicited by tone presentation was significantly smaller in amplitude, and tended to be delayed in time, in the AUD group compared with the control group, and the subsequent deceleration was also smaller in AUD patients. In both groups, the increase in HR was larger and occurred earlier when KCs were produced than when they were not, and there was no difference in the magnitude of the KC effect between groups. Phasic HR changes associated with KCs elicited by tones are impaired in AUD participants, reflecting ANS dysfunction possibly caused by an alteration of cardiac vagal trafficking. However, only the timing of the HR response was found to relate to estimated lifetime alcohol consumption in AUD. The clinical meaning and implications of these novel findings need to be determined.

Use of technology for delivery of mental health and substance use services to youth living with HIV: a mixed-methods perspective.

Disparities in HIV treatment outcomes among youth living with HIV (YLWH) present a challenge for ending the HIV epidemic. Antiretroviral therapy (ART) adherence can be impacted by comorbidities such as mental health and substance use. Technology use has shown promise in increasing access to mental health and substance use services. Using a mixed-methods approach, we conducted formative research to describe the relationship between mental health, substance use, and medication adherence in 18-29 year-old YLWH, and explored technology use as an approach to supporting these services. Among 101 YLWH, ART adherence was significantly negatively associated with mental health measures such as depression, trauma, and adverse childhood experiences and marijuana and stimulants use. Depression had the highest level of relative importance in its association with ART adherence. During in-depth interviews with 29 participants, barriers to and facilitators of accessing and maintaining mental health services were identified. Most participants favored technology use for mental health and substance use service delivery, including videoconferencing with a counselor. Provision of ongoing mental health and substance use treatment is an important mechanism to achieving HIV treatment engagement. Technology, particularly videoconferencing, may have the capacity to overcome many barriers to care by increasing accessibility of these services.

The embodiment of a floating signifier.

As described in ethnographies, the 'floating signifiers' of social anthropology appear akin to similar categories in contemporary Western societies such as energy. Both may be embodied in actual experience. The practice of ritual orgasm, Pra-Na, and its relation to the group's cosmology, are intrinsic to a religio-therapeutic community in San Francisco whose ideas derive from reified Western notions of 'vital energy' along with popular Chinese medicine, and in which the second author conducted fieldwork involving participant observation between 2008 and 2009. The article examines closely the formulations of 'energy' in the Western world, and similarities to non-Western concepts such as Melanesian mana, and asks whether the experience of ritualised orgasm by members of the group leads to their notion of cosmic energy, or whether the understanding of embodied energy is purely arbitrary from a somatic perspective. With reference to Durkheim's ([1912]1976. The Elementary Forms of the Religious Life. London: Allen & Unwin) -effervescence, we suggest the former is most likely.
