Background Heroin use may work synergistically with human immunodeficiency virus (HIV) infection to cause greater immune dysregulation than either factor alone. Unraveling how this affects end-organ disease is key as it may play a role in the excess mortality seen in people with HIV (PWH) who use heroin despite access to care and antiretroviral therapy. Methods This is a prospectively enrolled, cross-sectional study of adults with and without HIV who use and do not use heroin using (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) to compare tissue-specific inflammation including aortic (target-to-background ratio [TBR]), splenic, and bone marrow (standardized uptake value [SUV]). Results A total of 120 participants were enrolled. The unadjusted mean difference in aortic TBR was 0.43 between HIV-positive [HIV+] heroin+ and HIV+ heroin-negative [heroin−] (P =.02); however, among HIV−, aortic TBR was similar regardless of heroin-use status. Further, HIV-by-heroin-use status interaction was significant (P =.02), indicating that the relationship between heroin use and higher aortic TBR depended on HIV status. On the other hand, both HIV (1.54 vs 1.68; P =.04, unadjusted estimated means for HIV+ vs HIV−) and heroin use were associated with lower bone marrow SUV, although the effect of heroin depended on sex (heroin-use-by-sex interaction, P =.03). HIV-by-heroin-use interaction was not significant for splenic or bone marrow SUV. Conclusions Aortic inflammation was greatest in PWH who use heroin, but paradoxically, bone marrow activity was the least in this group, suggesting complex and possibly divergent pathophysiology within these different end organs.

Emerging research has examined the prevalence of severe acute respiratory syndrome virus 2 (SARS-CoV-2) infections in numerous settings, but a critical gap in knowledge is an understanding of the rate of infection among first responders. We conducted a prospective serial serologic survey by recruiting public first responders from Cleveland area emergency medical services agencies and fire departments. Volunteers submitted a nasopharyngeal swab for SARS-CoV-2 PCR testing and serum samples to detect the presence of antibodies to SARS-CoV-2 on two visits scheduled approximately 3 weeks apart. 296 respondents completed a first visit and 260 completed the second. While 71% of respondents reported exposure to SARS-CoV-2, only 5.4% (95% CI 3.1-8.6) had positive serologic testing. No subjects had a positive PCR. On the first visit, eight (50%) of the test-positive subjects had no symptoms and only one (6.2%) sought healthcare or missed school or work. None of the subjects that tested negative on the first visit were positive on their second. While our results show a relatively low rate of test positivity for SARS-CoV-2 amongst first responders, most were either asymptomatic or mildly symptomatic. The potential risk of asymptomatic transmission both between first responders and from first responders to vulnerable patients requires more study. [ABSTRACT FROM AUTHOR]

Objective aim Identify and eliminate barriers to HIV testing in primary care and to decrease the rates of patients never being tested, and limit unnecessary repeat testing. Setting Primary care clinics within an urban publicly funded safety net hospital and community health system in Cleveland, Ohio. Reported HIV prevalence among male Cleveland residents is 1193.5/100 000. Design A time series analysis using statistical process control was used. Methods Primary care encounters of patients aged 13-64 years from selected sites were reviewed throughout the initiative for HIV testing prior to the visit and associated with the visit. Results Run charts of the proportion of men and women never tested for HIV demonstrated marked improvement and special cause variation with six sequential quarters falling outside of the trend lines. Evaluation of encounters associated with a first HIV test confirmed testing occurring within primary care rather than elsewhere in the health system. Conclusions Implementing an electronic medical record-based reminder effectively increased HIV testing among primary care patients not previously tested, while education and practice feedback alone did not.

Women received <5% of all US pre-exposure prophylaxis (PrEP) prescriptions in 2016. Among 351 heterosexual women surveyed in Cleveland, Ohio, 14.5% were aware of PrEP, 20.5% knew where to access PrEP, 75.9% were willing to try PrEP, and 50.9% expressed interest in more information.
