Background: Pre-exposure prophylaxis (PrEP) medication is the keystone of preventative measures to curtail the spread of human immunodeficiency virus (HIV). However, oral PrEP, the tablet intended to prevent HIV, has been slow to proliferate among men who have sex with men (MSM). This is of major concern given that MSM account for the largest number of new HIV diagnoses in the United States.

Background: Identification of infection (CDI) in the community setting is increasing. We describe testing for CDI among patients with medically attended diarrhea (MAD) in the outpatient setting, and the incidence of outpatient CDI.

Methods: This was a retrospective cohort study among members ≥18 years of age from Kaiser Permanente Southern California and Kaiser Permanente Northwest from 1 January 2016 through 31 December 2021.

Discrimination is associated with antiretroviral therapy non-adherence and reduced well-being among people with HIV. We examined the potential for coping to mediate the associations between intersectional discrimination and non-adherence and coping self-efficacy (confidence in one's ability to cope with discrimination) as a moderator that may buffer the negative effects of discrimination on non-adherence in a cross-sectional convenience sample of 82 Latino sexual minority men with HIV. In bivariate linear regressions, discrimination targeting Latino ethnic origin, undocumented residency status, and sexual orientation were each significantly associated with lower self-reported antiretroviral therapy non-adherence (percentage of prescribed doses taken in the last month) and greater use of disengagement coping (denial, substance use, venting, self-blame, behavioral disengagement).

Introduction: The Centers for Disease Control and Prevention Guideline for Prescribing Opioids for Chronic Pain released in 2016 had led to decreases in opioid prescribing. This study sought to examine chronic and sustained high-dose prescription opioid use in an integrated health system.

Methods: A serial cross-sectional study was conducted in 2021 to estimate the annual age-adjusted prevalence and incidence of chronic and high-dose opioid use among demographically diverse noncancer adults in an integrated health system in Southern California during 2013-2020.

Article Synopsis
  • - The study explored Latinx immigrants' views on US policies that restrict their access to public resources and how these policies affect their use of healthcare services.
  • - Through 16 focus group discussions with 130 Latinx immigrants, four key themes emerged: perceptions of limited healthcare resources, fears about immigration consequences from seeking medical care, avoidance of entitled health services, and the impact of accurate vs. inaccurate information on healthcare access.
  • - Participants were aware of the negative portrayal of immigrants as burdens on public resources, leading to misunderstandings about laws and regulations that hindered their healthcare utilization; thus, providing clear information is essential to combat misinformation and improve immigrant access to healthcare.

We conducted a rapid, mixed-methods assessment to understand how COVID-19 affected Latinx sexual minority men (LSMM) and transgender women (LTGW). Using a computer-assisted telephone interviewing software, one interviewer called 52 participants (randomly sampled from a larger HIV prevention pilot study aiming to increase HIV knowledge and testing frequency; n = 36 LSMM and n = 16 LTGW) between 04/27/20-05/18/20. We quantified core domains using the Epidemic-Pandemic Impacts Inventory scale and provided important context through open-ended qualitative questions assessing: 1) COVID-19 infection history and experiences with quarantine; 2) Health and healthcare access; 3) Employment and economic impact of COVID-19.

We developed and pilot-tested an eight-session community-based cognitive behavior therapy group intervention to improve coping with intersectional stigma, address medical mistrust, and improve antiretroviral treatment adherence. Seventy-six HIV-positive Latinx sexual minority men (SMM; 38 intervention, 38 wait-list control) completed surveys at baseline, and 4- and 7-months post-baseline. Adherence was electronically monitored.

Objective: To determine how weekly text messages and small incentives impact HIV knowledge and frequency of HIV testing among Latinx sexual minority men (LSMM) and transgender women (LTGW).

Design: Prospectively randomized participants into 2 intervention arms compared with a nonrandomized comparison group.

Setting: Bienestar, a primarily Latinx focused HIV service provider located across Los Angeles County.

Objective: To compare the dwell times of ultrasound-guided and non-ultrasound-guided short peripheral intravenous catheters in hospitalized children.

Methods: This was a retrospective analysis of data from 256 ultrasound-guided and 287 traditional peripheral intravenous catheters placed in hospitalized children between 1 September2016 and 31 October 2016 at a free-standing children's hospital with a 10-member vascular access team. A two-sample independent test and Kaplan-Meier estimator were used to assess differences in dwell times between the ultrasound-guided peripheral intravenous catheters and non-ultrasound-guided peripheral intravenous catheters.

Mobile technology-based interventions show promise for conveying HIV prevention information to Latino men who have sex with men (LMSM) and Latina transgender women (LTGW); however, implementing such interventions can pose serious challenges. To understand how to adapt existing interventions for these populations, we conducted nine focus groups ( = 91 participants, 52 LMSM, 39 LTGW) in Los Angeles, California. We used a rapid assessment process to create narrative reports that we examined using thematic analysis to explore differences across sites and between LMSM and LTGW.

Background: Mobile Technology and Incentives (MOTIVES) is a randomized pilot study of a mobile technology-based and behavioral economics-supported HIV prevention intervention. Behavioral economics (BE) uses financial incentives in a way that departs from the traditional focus on large monetary payments. Instead, BE suggests that relatively small "nudges" can effectively initiate and sustain behavior change.

In this short communication, we discuss some key behavioral economic (BE) biases that likely minimize HIV prevention efforts, explore why certain key populations such as men who have sex with men or transgender women-may be more likely to succumb to these biases, and suggest how incentives informed by BE can support these populations in their effort to remain HIV-negative. Based on our formative work in an ongoing study, we discuss two important insights regarding the use of incentives to inform future HIV prevention efforts. First, participants often expressed more excitement for prizes that were viewed as fun (e.

Purpose: Children receiving treatment in the hospital frequently require intravenous (IV) access. Placement of short peripheral catheters can be painful and challenging especially in those children who have difficult access. Many children's hospitals have teams of specialized vascular access nurses experienced in peripheral catheter insertion, and at times use vein visualization devices, including ultrasound (US), to assist in peripheral IV placement.
