The Effect of Navigation on Linkage to a PrEP Provider Among PrEP-Eligible Men who have Sex with Men in a U.S. Demonstration Project.

Our objective is to evaluate the effect of navigation on linkage to a PrEP provider among PrEP-eligible men who have sex with men (MSM) in THRIVE, a demonstration project in seven U.S. public health jurisdictions during 2015-2020. We describe PrEP linkage and navigation use among MSM in THRIVE. We performed multivariable probit regression modeling, controlling for demographic covariates, to estimate the association between navigation and linkage to a PrEP provider among MSM and to assess for disparities in linkage to PrEP among MSM who used navigation. Among 9538 PrEP-eligible MSM, 51.3% used navigation and 53.8% were linked to PrEP. From the three sites where navigation was optional and the main form of PrEP support, MSM who used navigation were 16.69 times (95% CI 13.07-21.32) more likely to link to PrEP compared with MSM who did not use navigation. Among 4895 MSM who used navigation from all seven sites, Black MSM were 21% less likely to link to PrEP compared with White MSM (aRR 0.79; 95% CI 0.74-0.83). Navigation is a promising strategy for improving uptake of PrEP among U.S. MSM, but disparities persist. Addressing the underlying causes of inequities will be important to end the HIV epidemic.

Is Tailoring of PrEP Programs Needed to Overcome Racial Disparities in PrEP Uptake in Local Health Departments? A Mixed-Methods Evaluation of PrEP Implementation in Virginia.

CONTEXT: African American and Hispanic adults share a disproportionate burden of HIV infections in the United States but continue to experience suboptimal uptake of HIV pre-exposure prophylaxis (PrEP). Increasing PrEP accessibility in nontraditional care settings is a potential strategy to increase PrEP uptake in these high-risk groups. PrEP implementation in local health departments (LHDs) is not well characterized. OBJECTIVE: To evaluate HIV PrEP implementation for African American and Hispanic adults receiving medical care in Virginia's LHDs. DESIGN: We conducted a retrospective, mixed-methods evaluation of PrEP services implementation at LHDs completing their first PrEP program year between June 1, 2016, and June 30, 2019. Using pharmacy records, we estimated PrEP coverage and adherence using PrEP to need ratios (PnRs) and medication possession ratios (MPRs), respectively. Thematic analysis was used to identify barriers to PrEP delivery in interviews with 6 multidisciplinary LHD workers. RESULTS: Of the 433 PrEP clients receiving an emtricitabine/tenofovir disoproxil fumarate (Truvada) prescription in year 1, 52.0% self-identified as African American and 8.9% self-identified as Hispanic. PnRs were greater for White adults in 50.0% of clinics. The average MPR (0.79) was consistent with protective medication adherence levels; however, 25.0% of clients filled only one prescription in the program year. Qualitative findings suggest incompatibilities between health PrEP services delivery and community preferences for African American and Hispanic adults; however, LHDs in one health region were able to link communities of color to PrEP at similar rates as Whites. CONCLUSIONS: Incorporating a metric sensitive to racial/ethnic differences in the burden of HIV infection improved recognition of PrEP disparities; however, population-specific targets are needed to enhance use of the PnR for program evaluation. Tailoring of PrEP services to communities with the greatest local PrEP burden may be needed to optimize the effectiveness of PrEP programs in LHDs.

Development and evaluation of real-time loop-mediated isothermal amplification assay for rapid detection of cystic echinococcosis.

BACKGROUND: Cystic echinococcosis (CE) or hydatidosis, caused by the larval stage of Echinococcus granulosus (EG)-complex, is a neglected parasitic disease of public health importance. The disease is endemic in many African and Mediterranean countries including the Sudan. The objective of the present study was to develop and evaluate a real-time loop-mediated isothermal amplification (LAMP) assay for simple and rapid detection of CE in humans and domestic live stock in Sudan. METHODS: A set of six LAMP primers, designed from the mitochondrial NADH-1 gene of EG cattle strain of genotype 5 (G5), was used as a target for LAMP assay. The assay was performed at a constant temperature (63 °C), with a real-time follow-up using a LightCycler and fluorochrome dye. Following amplification cycles in a simple water bath, LAMP products were observed for color change by naked eye and were visualized under UV light source using agarose gel electrophoresis. RESULTS: The real-time LAMP assay identified a variety of hydatid cysts strains recovered in the Sudan, including Echinococcus canadenses (G6) and Echinococcus ortleppi (G5). Real-time LAMP positive results were detected by the presence of an amplification curve, whereas negative results were indicated by absence of fluorescence detection. Positive LAMP results appeared as a bluish-colored reaction as observed by naked eye, whereas negative LAMP results were observed as purple-colored reaction. The sensitivity studies indicated that the LAMP assay detected as little as a 10 fg of parasite DNA. There was 100 % agreement between results of the LAMP assay and our previously described nested PCR when testing 10-fold serial dilution of DNA extracted from EG-complex hydatid cyst. However, there was no cross-reactivity with other parasites including cysticercus bovis, Fasciola gigantica, and Schistosoma bovis and nucleic acid free samples. CONCLUSION: The developed LAMP assay would be expected to prove highly significant in epidemiological surveys of CE in developing countries or areas of resource-poor settings for both ease of use and cost.

Prenatal psychological distress and 11ß-HSD2 gene expression in human placentas: Systematic review and meta-analysis.

BACKGROUND: The placenta acts as a buffer to regulate the degree of fetal exposure to maternal cortisol through the 11-Beta Hydroxysteroid Dehydrogenase isoenzyme type 2 (11-ß HSD2) enzyme. We conducted a systematic review and meta-analysis to assess the effect of prenatal psychological distress (PPD) on placental 11-ß HSD2 gene expression and explore the related mechanistic pathways involved in fetal neurodevelopment. METHODS: We searched PubMed, Embase, Scopus, APA PsycInfo®, and ProQuest Dissertations for observational studies assessing the association between PPD and 11-ß HSD2 expression in human placentas. Adjusted regression coefficients (ß) and corresponding 95% confidence intervals (CIs) were pooled based on three contextual PPD exposure groups: prenatal depression, anxiety symptoms, and perceived stress. RESULTS: Of 3159 retrieved records, sixteen longitudinal studies involving 1869 participants across seven countries were included. Overall, exposure to PPD disorders showed weak negative associations with the placental 11-ß HSD2 gene expression as follows: prenatal depression (ß -0.01, 95% CI 0.05-0.02, I2=0%), anxiety symptoms (ß -0.02, 95% CI 0.06-0.01, I2=0%), and perceived stress (ß -0.01 95% CI 0.06-0.04, I2=62.8%). Third-trimester PPD exposure was more frequently associated with lower placental 11-ß HSD2 levels. PPD and placental 11-ß HSD2 were associated with changes in cortisol reactivity and the development of adverse health outcomes in mothers and children. Female-offspring were more vulnerable to PPD exposures. CONCLUSION: The study presents evidence of a modest role of prenatal psychological distress in regulating placental 11-ß HSD2 gene expression. Future prospective cohorts utilizing larger sample sizes or advanced statistical methods to enhance the detection of small effect sizes should be planned. Additionally, controlling for key predictors such as the mother's ethnicity, trimester of PPD exposure, mode of delivery, and infant sex is crucial for valid exploration of PPD effects on fetal programming.

First report on circulation of Echinococcus ortleppi in the one humped camel (Camelus dromedaries), Sudan.

BACKGROUND: Echinococcus granulosus (EG) complex, the cause of cystic echinococcosis (CE), infects humans and several other animal species worldwide and hence the disease is of public health importance. Ten genetic variants, or genotypes designated as (G1-G10), are distributed worldwide based on genetic diversity. The objective of this study was to provide some sequence data and phylogeny of EG isolates recovered from the Sudanese one-humped camel (Camelus dromedaries). Fifty samples of hydatid cysts were collected from the one- humped camels (Camelus dromedaries) at Taboul slaughter house, central Sudan. DNAs were extracted from protoscolices and/or associated germinal layers of hydatid cysts using a commercial kit. The mitochondrial NADH dehydrogenase subunit 1 (NADH1) gene and the cytochrome C oxidase subunit 1 (cox1) gene were used as targets for polymerase chain reaction (PCR) amplification. The PCR products were purified and partial sequences were generated. Sequences were further examined by sequence analysis and subsequent phylogeny to compare these sequences to those from known strains of EG circulating globally. RESULTS: The identity of the PCR products were confirmed as NADH1 and cox1 nucleotide sequences using the Basic Local Alignment Search Tool (BLAST) of NCBI (National Center for Biotechnology Information, Bethesda, MD). The phylogenetic analysis showed that 98% (n = 49) of the isolates clustered with Echinococcus canadensis genotype 6 (G6), whereas only one isolate (2%) clustered with Echinococcus ortleppi (G5). CONCLUSIONS: This investigation expands on the existing sequence data generated from EG isolates recovered from camel in the Sudan. The circulation of the cattle genotype (G5) in the one-humped camel is reported here for the first time.

HIV Pre-exposure Prophylaxis Services for Black and Hispanic or Latino Gay, Bisexual, and Other Men Who Have Sex With Men and Transgender Women in THRIVE, 2015-2020.

BACKGROUND AND SETTING: From 2015 to 2020, the THRIVE project supported 7 US health departments to improve HIV prevention services for Black or African American (Black) and Hispanic or Latino gay, bisexual, and other men who have sex with men (GBM) and transgender women (TGW). METHODS: We described services provided in the THRIVE PrEP continuum. Using Poisson regression models, we estimated associations between race or ethnicity and age and PrEP screening, linkage, and prescription. We examined associations between colocation of services and PrEP linkage and prescription for 2 sites. RESULTS: THRIVE served 12,972 GBM without HIV; 37% of PrEP-eligible GBM were prescribed PrEP. THRIVE served 1185 TGW without HIV; 45% of PrEP-eligible TGW were prescribed PrEP. Black and Hispanic or Latino GBM were 29% (RR = 0.71, 95% CI: 0.66-0.77) and 19% (RR = 0.81, 95% CI: 0.75-0.87) less likely, respectively, to be prescribed PrEP than White GBM. GBM aged 18-24 years and 55 years or older were 19% (RR = 0.81, 95% CI: 0.75-0.87) and 22% (RR = 0.78, 95% CI: 0.67-0.9) less likely, respectively, to be prescribed PrEP compared with those aged 35-44 years. Colocated services were associated with a 54% (RR = 1.54, 95% CI: 1.44-1.64) and a 31% (RR = 1.31, 95% CI: 1.19-1.43) greater likelihood of PrEP linkage and prescription, respectively, compared with services at different locations. CONCLUSIONS: THRIVE provided PrEP to higher proportions of PrEP-eligible persons than current national estimates; however, PrEP use disparities persist. Colocation of services may be a useful component of jurisdictional strategies to increase PrEP coverage.

Assessment of Knowledge, Attitudes, and Readiness to Practice Regarding Disaster Medicine and Preparedness Among University Health Students.

OBJECTIVES: The aim of this study is to assess the knowledge (K), attitude (A), and readiness to practice (rP) levels regarding disaster medicine and preparedness among health profession students at Qatar University. METHODS: A survey-based study was carried out to assess medical, pharmacy, and health sciences students' KArP levels using pretested and validated questionnaire. Student's t-test, analysis of variance, correlation, and linear regression were used with an alpha level of 0.05. RESULTS: The difference in the mean KArP level between genders was not significant (P > 0.05). Students from the College of Health Sciences had significantly higher KArP levels than those from the College of Pharmacy (101.5 vs 90.0; P = 0.033). Overall, Qatari students had better knowledge, attitude, and readiness to practice scores and total KArP scores than non-Qatari students. Moreover, students who were born in Qatar also had better knowledge, attitude, and readiness to practice scores and total KArP scores than students who were born outside Qatar. Significant direct moderate correlations were found among the 3 KArP parameters (P < 0.001). Knowledge and attitudes were indicated to be significant predictors of readiness to practice (P < 0.001). CONCLUSIONS: Students from the health colleges at Qatar University have moderate disaster medicine preparedness.

The "No Wrong Door" Approach to HIV Testing: Results From a Statewide Retail Pharmacy-Based HIV Testing Program in Virginia, 2014-2016.

OBJECTIVE: As part of the Care and Prevention in the United States Demonstration Project (2012-2016), which aimed to reduce HIV-related morbidity and mortality among racial/ethnic minority groups in 8 states, the Virginia Department of Health (VDH) funded Walgreens to provide HIV testing in retail pharmacies in areas with large racial/ethnic minority communities and high rates of poverty. We describe this program and summarize its outcomes. We hypothesized that (1) offering walk-in HIV testing outside of traditional business hours and alongside other point-of-care tests in retail pharmacies would increase rates of first-time testers and (2) using data on social determinants of health associated with higher rates of HIV infection to locate test sites would increase the identification of people who were previously undiagnosed. METHODS: Using 2010 US Census data and 2007-2011 five-year population estimates from the American Community Survey, VDH selected 32 Walgreens stores located in census tracts where at least 30% of the population was black and/or Hispanic/Latino and/or where at least 20% of the population was living at or below the federal poverty level. Pharmacists administered the INSTI HIV-1/HIV-2 Rapid Antibody Test. Clients with a reactive test result were linked to confirmatory testing and medical care. RESULTS: Between June 1, 2014, and September 29, 2016, Walgreens pharmacists performed HIV tests on 3630 clients, of whom 1668 (46.0%) had either never been tested or were unsure if they had been tested. Of all clients tested, 30 (0.8%) had a reactive test result. Of 26 clients who also had positive confirmatory testing, 22 (84.6%) were linked to care. The mean cost per person tested was $41.79, and the mean cost per reactive result was $5057. CONCLUSIONS: Retail pharmacies may be an effective venue for those who have never been tested for HIV to access HIV testing, particularly if the pharmacies are located in priority areas or where community-based organizations are unable to operate.
