We characterized polysubstance use burden and associations with mental health problems across demographic subgroups of PWH. In 2018–2020, as part of a primary care-based intervention study, PWH in care at three medical centers in Kaiser Permanente Northern California were screened for depression (PHQ-9≥10), anxiety (GAD-2≥3), and substance use (Tobacco, Alcohol, Prescription medication, and other Substance use [TAPS]≥1 per substance). We used Poisson regression to estimate prevalence ratios (PRs) comparing polysubstance use prevalence (TAPS≥1 for ≥2 substances) between PWH with positive screens for depression or anxiety vs. neither, among all PWH, and stratified by race/ethnicity and age (restricted to men), adjusting for sociodemographics, CD4, and HIV load. Screened PWH (N = 2865) included 92% men, 56% White, 19% Black, and 15% Hispanic PWH, with a median age of 55 years. Overall, polysubstance use prevalence was 26.4% (95% CI 24.9%-28.1%). PWH with depression or anxiety (n = 515) had an adjusted polysubstance use PR of 1.26 (1.09–1.46) vs. PWH with neither (n = 2350). Adjusted PRs were 1.47 (1.11–1.96), 1.07 (0.74–1.54), and 1.10 (0.85–1.41) among Black, Hispanic, and White men, respectively. Adjusted PRs did not differ by age group. Interventions should consider jointly addressing mental health and substance use problems and potential drivers, e.g. stigma or socioeconomic factors. [ABSTRACT FROM AUTHOR]

Background Rapid antiretroviral therapy (ART) is the recommended treatment strategy for patients newly diagnosed with HIV, but the literature supporting this strategy has focused on short-term outcomes. We examined both long-term outcomes and predictors of rapid ART among patients newly diagnosed with HIV within an integrated health care system in Northern California. Methods This observational cohort study included adults newly diagnosed with HIV between January 2015 and December 2020 at Kaiser Permanente Northern California. Rapid ART was defined as ART initiation within 7 days of HIV diagnosis. We collected demographic and clinical data to determine short-term and long-term outcomes, including viral suppression, care retention, medication adherence, and cumulative viral burden. Logistic regression models were used to identify predictors of rapid ART initiation. Results We enrolled 1409 adults; 34.1% initiated rapid ART. The rapid ART group achieved viral suppression faster (48 vs 77 days; P <.001) and experienced lower cumulative viral burden (log10 viremia copy-years, 3.63 vs 3.82; P <.01) but had slightly reduced medication adherence (74.8% vs 75.2%; P <.01). There was no improvement in long-term viral suppression and care retention in the rapid group during follow-up. Patients were more likely to initiate rapid ART after 2017 and were less likely if they required an interpreter. Conclusions Patients who received rapid ART had an improved cumulative HIV burden but no long-term improvement in care retention and viral suppression. Our findings suggest that rapid ART should be offered but additional interventions may be needed for patients newly diagnosed with HIV. [ABSTRACT FROM AUTHOR]

Outcomes of PWH with unhealthy alcohol use, such as alcohol use reduction or progression to AUD, are not well-known and may differ by baseline patterns of unhealthy alcohol use. Among 1299 PWH screening positive for NIAAA-defined unhealthy alcohol use in Kaiser Permanente Northern California, 2013–2017, we compared 2-year probabilities of reduction to low-risk/no alcohol use and rates of new AUD diagnoses by baseline use patterns, categorized as exceeding: only daily limits (72% of included PWH), only weekly limits (17%), or both (11%), based on NIAAA recommendations. Overall, 73.2% (95% CI 70.5–75.9%) of re-screened PWH reduced to low-risk/no alcohol use over 2 years, and there were 3.1 (95% CI 2.5–3.8%) new AUD diagnoses per 100 person-years. Compared with PWH only exceeding daily limits at baseline, those only exceeding weekly limits and those exceeding both limits were less likely to reduce and likelier to be diagnosed with AUD during follow-up. PWH exceeding weekly drinking limits, with or without exceeding daily limits, may have a potential need for targeted interventions to address unhealthy alcohol use. [ABSTRACT FROM AUTHOR]

The coronavirus disease 2019 (COVID-19) pandemic disrupted health systems. For patients newly diagnosed with human immunodeficiency virus, starting immediate antiretroviral therapy (ART) is recommended. For periods before and during the COVID-19 pandemic, Kaiser Permanente Northern California found similar rates of rapid ART initiation and time to viral suppression, concurrent with an increase in telemedicine.

In this paper we report the main test results obtained on the Poloidal Field Conductor Insert coil (PFI) for the International Thermonuclear Experimental Reactor (ITER), built jointly by the EU and RF ITER parties, recently installed and tested in the CS Model Coil facility, at JAEA-Naka. During the test we (a) verified the DC and AC operating margin of the NbTi Cable-in-Conduit Conductor in conditions representative of the operation of the ITER PF coils, (b) measured the intermediate conductor joint resistance, margin and loss, and (c) measured the AC loss of the conductor and its changes once subjected to a significant number of Lorentz force cycles. We compare the results obtained to expectations from strand and cable characterization, which were studied extensively earlier. We finally discuss the implications for the ITER PF system.

People with HIV (PWH) are at elevated risk for suicidal ideation (SI), yet few studies have examined how substance use, clinical and sociodemographic factors are associated with SI among PWH. We used substance use (Tobacco, Alcohol, Prescription Medication, and Other Substance Use [TAPS]) and depression (PHQ-9) data from computerized screening of adult PWH in primary care clinics in Northern California, combined with health record data on psychiatric diagnoses, HIV diagnosis, treatment, and control (HIV RNA, CD4), insurance, and neighborhood deprivation index (NDI) to examine factors associated with SI (PHQ-9 item 9 score > 0). Adjusted odds ratios (aOR) for SI were obtained from logistic regression models. Among 2829 PWH screened (92 % male; 56 % white; mean (SD) age of 54 (13) years; 220 (8 %) reported SI. Compared with no problematic use, SI was higher among those reporting one (aOR = 1.65, 95 % CI = 1.17, 2.33), two (aOR = 2.23, 95 % CI = 1.42, 3.49), or ≥ 3 substances (aOR = 4.49, 95 % CI = 2.41, 8.39). SI risk was higher for those with stimulant use (aOR = 3.55, 95 % CI = 2.25, 5.59), depression (aOR = 4.18, 95 % CI = 3.04, 5.74), and anxiety diagnoses (aOR = 1.67, 95 % CI = 1.19, 2.34), or Medicaid (aOR = 2.11, 95%CI = 1.24, 3.60) compared with commercial/other insurance. SI was not associated with HIV-related measures or NDI. SI was assessed with a single PHQ-9 item. Simultaneous SI and exposure data collection restricts the ability to establish substance use as a risk factor. HIV care providers should consider multiple substance use, stimulant use, depression or anxiety, and public insurance as risk factors for SI and provide interventions when needed. • People with HIV (PWH) are at elevated risk for suicidal ideation (SI). • Computerized screening in primary care can help identify those at risk. • SI risk increased with greater number of substances patients reported using. • Stimulant use, depression, anxiety, and public insurance were associated with SI. • Providers should assess key risk factors to address SI among PWH.

Purpose: The COVID-19 pandemic impacted testing and incidence of sexually transmitted infections (STIs), with some studies showing uneven effects across sociodemographic groups. We aim to determine whether rates of gonorrhea and chlamydia testing and infections were affected by the pandemic, overall and by subgroups, defined by sociodemographic factors and comorbidities., Methods: We conducted a retrospective cohort study from January 1, 2016, through December 31, 2022, among adolescents and young adults ages 15-29 years within Kaiser Permanente Northern California (KPNC). We determined the rate of testing for gonorrhea/chlamydia, and the incident rates of infections before and during the COVID-19 pandemic by sociodemographic factors. We compared incidence rates of gonorrhea/chlamydia testing and infection before and during the pandemic using Poisson regression., Results: Gonorrhea/chlamydia testing during the pandemic was 19% lower than prepandemic baseline. Testing among Black patients was 1.8-fold higher than White patients. Black patients had 5.5 and 3.6-fold higher rate of gonorrhea and chlamydia infections, respectively, compared with White patients. Patients living in more deprived neighborhoods also had higher rates of infection compared to those in the least deprived neighborhoods. In multivariable analyses stratified by the period before and during the COVID-19 pandemic, there were no significant differences in the incidence rate ratios of testing or infections for any specific sociodemographic factor., Discussion: STI testing in adolescents and young adults dropped dramatically after the start of the pandemic and has not recovered to its prior levels. Preexisting disparities in STI testing and infections were not exacerbated by the pandemic., (Copyright © 2024 Society for Adolescent Health and Medicine. Published by Elsevier Inc.
