Effect of Education on Adherence to Recommended Prenatal Practices among Indigenous Ngäbe-Buglé Communities of Panama.

Background and Objectives: The primary objective of this study was to assess the adherence of Ngäbe-Buglé women to WHO-recommended prenatal practices. The secondary objective was to compare adherence levels between women who received prenatal education from official medical providers and those educated through traditional or community-based sources within Ngäbe-Buglé communities. Materials and Methods: An eight-question survey was verbally administered to 137 Ngäbe-Buglé women at clinics set up by the non-profit NGO Floating Doctors in eight communities. A two-sided Fisher's Exact test with a p = 0.05 was used to compare the results of mothers who received prenatal education from evidence-based sources to other groups. Results: Out of the 137 surveyed women, 65 reported taking prenatal vitamins, 21 had prenatal check-ups, 136 avoided alcohol, 31 increased caloric intake, and 102 maintained their activity levels. Significant differences were observed in prenatal vitamin adherence between those educated by official sources versus unofficial sources (p = 0.0029) and official sources compared to those with no prenatal education (p < 0.0001). The difference was also significant for education from an unofficial source versus no education (p = 0.0056). However, no significant differences were found in other prenatal practices based on education sources. Conclusions: Our findings highlight deficiencies in both prenatal education and adherence to recommended practices among Ngäbe-Buglé women. Prenatal education significantly improved adherence to taking prenatal vitamins, suggesting its effectiveness as an intervention. Future interventions should prioritize culturally competent prenatal education and address barriers to accessing prenatal healthcare in Ngäbe-Buglé communities.

High Rates of Missed HIV Testing Among Oral PrEP Users in the United States From 2018-2021: A National Assessment on Compliance With HIV Testing Recommendations of the CDC PrEP Guidelines.

Background: The US Centers for Disease Control and Prevention recommends HIV testing every 3 months in oral PrEP users. We performed a national assessment of HIV testing compliance among oral PrEP users. Methods: We analyzed 408 910 PrEP prescriptions issued to 39 809 PrEP users using a national insurance claims database that contained commercial and Medicaid claims. We identified PrEP use based on pharmacy claims and outpatient diagnostic coding. We evaluated the percentage of PrEP prescription refills without HIV testing (identified by CPT codes) within the prior 3, 6, and 12 months using time to event methods. We performed subgroup and multivariate analyses by age, gender, race, insurance type, and geography. Results: Of 39 809 persons, 36 197 were commercially insured, 3612 were Medicaid-insured, and 96% identified as male; the median age (interquartile range) was 34 (29-44) years, and the Medicaid-insured PrEP users were 24% Black/African American, 44% White, and 9% Hispanic/Latinx. Within the prior 3, 6, and 12 months, respectively, the percentage of PrEP prescription fills in individuals without HIV Ag/Ab testing was 34.3% (95% CI, 34.2%-34.5%), 23.8% (95% CI, 23.7%-23.9%), and 16.6% (95% CI, 16.4%-16.7%), and the percentage without any type of HIV test was 25.8% (95% CI, 25.6%-25.9%), 14.6% (95% CI, 14.5%-14.7%), and 7.8% (95% CI, 7.7%-7.9%). Conclusions: Approximately 1 in 3 oral PrEP prescriptions were filled in persons who had not received an HIV Ag/Ab test within the prior 3 months, with evidence of health disparities. These findings inform clinical PrEP monitoring efforts and compliance with national HIV testing guidance to monitor PrEP users.

The plasma separation card as a novel solution for enhancing central laboratory capability for HIV-1 viral load monitoring in limited-access settings.

Measurement of HIV-1 viral load (VL) is essential for monitoring antiretroviral treatment (ART) efficacy. The preferred specimen type for VL is plasma, but in remote settings where collection and preservation of plasma many not be possible, dried blood spots (DBS) are often used instead. A new specimen collection matrix, the cobas plasma separation card (PSC, Roche Diagnostics Solutions), enables specimen preparation from a finger prick or venous blood, using a multi-layer absorption and filtration design that results in a specimen similar to dried plasma. We sought to confirm the correlation between VL results obtained using PSC prepared from venous blood to those from plasma or DBS, as well as PSC prepared with capillary blood from a finger prick. PSC, DBS and plasma were prepared with blood from HIV-1 infected persons attending a primary care clinic in Kampala, Uganda. VL in PSC and plasma was measured using cobas HIV-1 (Roche Diagnostics), while VL in DBS was measured with RealTime HIV-1 (Abbott Diagnostics). The correlation between VL from plasma and PSC made from capillary or venous blood was high (regression coefficient of determination r2 between 0.87 and 0.91), and there was good agreement based on mean bias (-0.14 to 0.24 log10 copies/mL) and classification of VL above or below 1000 copies/mL (91.4% agreement). In contrast, VL from DBS was lower than plasma or PSC (mean bias 0.51 to 0.63 log10 copies/mL) and not as well correlated (r2 0.78 to 0.81, 75.1-80.5% agreement). These results confirm the utility of PSC as an alternative specimen type for HIV-1 viral load measurement in areas where preparation and optimal storage or shipment of plasma is an obstacle to provision of treatment and care of HIV-1 infected people.
