Psychosocial syndemic conditions have received more attention regarding their deleterious effects on HIV acquisition risk than for their potential impact on HIV treatment and viral suppression. To examine syndemic conditions' impact on the HIV care continuum, we analyzed data collected from people living with HIV (N = 14,261) receiving care through The Centers for AIDS Research Network of Integrated Clinical Systems at seven sites from 2007 to 2017 who provided patient-reported outcomes ∼4-6 months apart. Syndemic condition count (depression, anxiety, substance use, and hazardous drinking), sexual risk group, and time in care were modeled to predict antiretroviral therapy (ART) adherence and viral suppression (HIV RNA less then 400 copies/mL) using multilevel logistic regression. Comparing patients with each other, odds of ART adherence were 61.6% lower per between-patient syndemic condition [adjusted odds ratio (AOR) = 0.384; 95% confidence interval (CI), 0.362-0.408]; comparing patients with themselves, odds of ART adherence were 36.4% lower per within-patient syndemic condition (AOR = 0.636 95% CI, 0.606-0.667). Odds of viral suppression were 29.3% lower per between-patient syndemic condition (AOR = 0.707; 95% CI, 0.644-0.778) and 27.7% lower per within-patient syndemic condition (AOR = 0.723; 95% CI, 0.671-0.780). Controlling for the effects of adherence (AOR = 5.522; 95% CI, 4.67-6.53), each additional clinic visit was associated with 1.296 times higher odds of viral suppression (AOR = 1.296; 95% CI, 1.22-1.38), but syndemic conditions were not significant. Deploying effective interventions within clinics to identify and treat syndemic conditions and bolster ART adherence and continued engagement in care can help control the HIV epidemic, even within academic medical settings in the era of increasingly potent ART.Our objective was to estimate the prevalence of pre-exposure prophylaxis (PrEP) eligibility, characterize self-perceived and quantified human immunodeficiency virus (HIV) risk, and assess PrEP knowledge and receptiveness of initiating PrEP among emergency department (ED) patients. We performed an IRB-approved cross-sectional study from two urban EDs. Patients were eligible if ≥18 years of age and not known to have HIV. Research staff obtained verbal consent and used a structured 29-item instrument to assess HIV risk, PrEP eligibility based on 2017 Centers for Disease Control and Prevention (CDC) guidelines, and general PrEP knowledge among unselected and enriched patient samples, the latter informed by the Denver HIV Risk Score (DHRS). We enrolled 1002 patients with a median age of 39 years; 54.8% were male, 30.9% White/non-Hispanic, 29.5% Black/non-Hispanic, and 22.5% Hispanic. In the full cohort, 119 [11.9%, 95% confidence interval (CI) 9.9-14.0%] were PrEP eligible, and among the unselected cohort, 36 (7.1%, 95% CI 5.1-9.8%) were PrEP eligible. Using the DHRS, 100 patients were considered "high risk" with 32 (32.0%) reporting zero perceived risk. Correlation between the DHRS and self-perceived HIV risk was low (r = 0.13). Of the full cohort, 203 (20.3%) had heard of PrEP, and of these, 33 (16.3%) were PrEP eligible with 25 (75.8%) willing to start PrEP immediately. Yet, of the 119 patients who were PrEP eligible, only 34 (28.6%) had heard of PrEP. check details In summary, among a heterogeneous ED population, there was discordance in self-perceived and quantified HIV risk. HIV PrEP eligibility was ∼7% with the highest eligibility among those identified as DHRS "high risk." A significant opportunity exists to identify and initiate PrEP among ED patients.Men who have sex with men (MSM) and who are unaware of their HIV infection contribute to onward HIV transmission and are more likely to progress to severe illness. We therefore assessed determinants of never testing for HIV among MSM living in the Netherlands. Between April and July 2019, 950 HIV-negative and 122 never-tested MSM completed a cross-sectional survey on sociodemographics, HIV testing behavior, and sexual risk taking, which was distributed through gay networking sites/apps. In never-tested MSM, median age was 37 (interquartile range = 22-51) years and 37 (30%) reported recent sexual risk behavior. Never testing was associated with younger age [adjusted odds ratio (aOR) per year increase = 0.98, 95% confidence interval (CI) = 0.97-1.00, p = 0.015], having sex with men and women (aOR = 2.85, 95% CI = 1.57-5.62, p = 0.001), and not knowing others living with HIV (aOR = 3.85, 95% CI = 2.35-6.32, p  less then  0.001) in multi-variable logistic regression analysis. A significant interaction effect between education level and residential area was observed (p = 0.001). Among higher-educated MSM, those living outside a large urban area had higher odds of never testing compared to those living in an urban area (aOR = 6.26, 95% CI = 2.42-16.24, p  less then  0.001). Lower-educated MSM had higher odds of never testing irrespective of residential area (large urban area aOR = 12.06, 95% CI = 4.00-36.38; outside large urban area aOR 9.29, 95% CI = 3.64-23.76; p  less then  0.001 for both). Among MSM recently exposed to sexual risk, never testing was associated with having sex with men and women (aOR = 2.80, 95% CI = 1.09-7.18, p = 0.032) and not knowing others with HIV (aOR = 4.91, 95% CI = 1.97-12.24, p = 0.001). To conclude, testing interventions for those never tested should be tailored to residential area and education level, and inclusive of bisexuality.Zebrafish (Danio rerio) are an attractive model organism for a variety of scientific studies, including host-microbe interactions. The organism is particularly useful for the study of aquatic microbes that can colonize vertebrate hosts, including Vibrio cholerae, an intestinal pathogen. V. cholerae must colonize the intestine of an exposed host for pathogenicity to occur. While numerous studies have explored various aspects of the pathogenic effects of V. cholerae on zebrafish and other model organisms, few, if any, have examined how a V. cholerae infection alters the resident intestinal microbiome and the role of the type six secretion system (T6SS) in that process. In this study, 16S rRNA gene sequencing was utilized to investigate how strains of V. cholerae both with and without the T6SS alter the aforementioned microbial profiles following an infection. V. cholerae infection induced significant changes in the zebrafish intestinal microbiome, and while not necessary for colonization, the T6SS was essential for inducing mucin secretion, a marker for diarrhea.
