BACKGROUND: Low-density asymptomatic Plasmodium infections are prevalent in endemic areas, but little is known about their natural history. The trajectories of these infections and their propensity to fluctuate to undetectable densities can affect detection in clinical trials and field studies. We aimed to classify the natural history of these infections in a high transmission area over 29 days. METHODS: In this longitudinal cohort study, we enrolled healthy, malaria-asymptomatic, afebrile, adults (age 18-59 years) and older children (age 8-17 years) in Katakwi District, Uganda, who were negative for Plasmodium infection on rapid diagnostic tests. Participants were instructed to self-collect one dried blood spot (DBS) per day for a maximum of 29 days. We excluded people if they were pregnant or taking antimalarials. During weekly clinic visits, staff collected a DBS and a 4 mL sample of venous blood. We analysed DBSs by Plasmodium 18S rRNA quantitative RT-PCR (qRT-PCR). We classified DBS by infection type as negative, P falciparum, non-P falciparum, or mixed. We plotted infection type over time for each participant and categorised trajectories as negative, new, cleared, chronic, or indeterminate infections. To estimate the effect of single timepoint sampling, we calculated the daily prevalence for each study day and estimated the number of infections that would have been detected in our population if sampling frequency was reduced. FINDINGS: Between April 9 and May 20, 2021, 3577 DBSs were collected by 128 (40 male adults, 60 female adults, 12 male children, and 16 female children) study participants. 2287 (64%) DBSs were categorised as negative, 751 (21%) as positive for P falciparum, 507 (14%) as positive for non-P falciparum, and 32 (1%) as mixed infections. Daily Plasmodium prevalence in the population ranged from 45·3% (95% CI 36·6-54·1) at baseline to 30·3% (21·9-38·6) on day 24. 37 (95%) of 39 P falciparum and 35 (85%) of 41 non-P falciparum infections would have been detected with every other day sampling, whereas, with weekly sampling, 35 (90%) P falciparum infections and 31 (76%) non-P falciparum infections would have been detected. INTERPRETATION: Parasite dynamics and species are highly variable among low-density asymptomatic Plasmodium infections. Sampling every other day or every 3 days detected a similar proportion of infections as daily sampling, whereas testing once per week or even less frequently could misclassify up to a third of the infections. Even using highly sensitive diagnostics, single timepoint testing might misclassify the true infection status of an individual.

BACKGROUND: Pregnancy represents a period of high HIV acquisition risk. Safety data for the monthly dapivirine vaginal ring (DVR) during pregnancy are limited. Here, we report data from the first 2 cohorts of pregnant participants in MTN-042/DELIVER, a phase 3b, randomized, open-label safety trial of DVR and oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). MTN-042 is being conducted in 3 cohorts beginning with later gestational ages when risks of drug exposure are less. METHODS: Eligible pregnant individuals aged 18-40 years in Malawi, South Africa, Uganda, and Zimbabwe were randomized 2:1 to monthly DVR or daily TDF/FTC. Participants in cohort 1 initiated product use between 36 weeks 0 days (36 0/7 weeks) and 37 6/7 weeks gestation; participants in cohort 2 initiated product use between 30 0/7 and 35 6/7 weeks gestation. All participants continued product use until delivery or 41 6/7 weeks gestation. Pregnancy outcomes and complications were assessed and summarized using descriptive statistics and compared with local background rates obtained through a separate chart review. RESULTS: One-hundred and fifty participants were enrolled into cohort 1 with 101 randomized to DVR and 49 to TDF/FTC. One-hundred and fifty-seven participants were enrolled into cohort 2 with 106 randomized to DVR and 51 to TDF/FTC. In both cohorts, pregnancy complications were rare and similar to local background rates. CONCLUSION: In this first study of a long-acting HIV prevention agent in pregnancy, adverse pregnancy outcomes and complications were uncommon when DVR and TDF/FTC were used in the third trimester of pregnancy, suggesting a favorable safety profile for both prevention products.

INTRODUCTION: Although great heterogeneity and resilience exist among American Indians and Alaska Natives, Native Hawaiians and other Pacific Islanders, and Indigenous Latinx Populations across the United States, epidemiological data demonstrate these groups share a troubling commonality with respect to persistent health inequities, including HIV. A strong network of highly trained and productive Indigenous scientists dedicated to research that is culturally grounded is one component of a multifaceted approach that would contribute to ameliorating HIV-related disparities among Indigenous populations. METHODS: Building on the only long-standing Indigenous-specific HIV/AIDS mentorship program in the United States-the Indigenous HIV/AIDS Research Training Program and with support from the CFAR Diversity, Equity, and Inclusion Pathway Initiative, the University of Washington/Fred Hutch CFAR developed and launched the Building Indigenuity, Generating HIV Science: HIV/AIDS Research Training Program (BIG HART) to introduce undergraduate and graduate Indigenous scholars to the field of HIV research. RESULTS: The BIG HART program includes a seminar series to introduce undergraduate and graduate Indigenous scholars to the field of HIV research, opportunities to connect scholars with Indigenous mentors and provide networking opportunities to facilitate training opportunities related to HIV science, and complementary training for mentors to enhance their knowledge and training related to mentoring across difference, with a specific focus on mentoring Indigenous scholars. CONCLUSIONS: The BIG HART program is an important starting point toward building a sustainable program to attract Indigenous scholars in the field of HIV and grow and empower the next generation of Indigenous HIV scientists.

Provision of medication abortion in student health centers is safe and effective, but no public universities in Washington state provide such services. We estimate demand for medication abortion and describe barriers to care among students at four-year public universities in Washington. Using publicly available data, we estimated that students at the 11 Washington public universities obtained between 549 and 932 medication abortions annually. Students must travel an average of 16 miles (range:1-78) or 73 minutes via public transit (range:22-284) round trip to the nearest abortion-providing facility. Average wait time for the first available appointment was 10 days (range:4-14), and average cost was $711. Public universities can play an integral role in expanding abortion access post-Dobbs by providing medication abortion, effectively reducing barriers to care for students. The state legislature can pass legislation requiring universities to provide medication abortion, similar to what other states also protective of abortion rights have done.

This study examines qualitative acceptability of the dapivirine vaginal ring (DVR) and oral daily pre-exposure prophylaxis (PrEP) among breastfeeding persons participating in Microbicide Trials Network 043/B-PROTECTED, a phase 3B safety and drug detectability study of DVR and oral PrEP in breastfeeding. A subsample of 52 participants were purposively sampled to participate in an in-depth interview (IDI). Breastfeeding participants found both study products to be acceptable, and easy to use. A common motivation for product use was to protect the baby from HIV, although participants' understanding of how the study drug would work to protect their babies was often unclear. While most participants did not report experiencing side effects, fears about side effects were common as both initial worries about how the study products would affect their health and the health of their baby, and increased anxiety that health issues experienced by them, or their baby were from the products.

BACKGROUND: It is estimated that there are one million transgender and over 340,000 gender non-conforming people in the United States, many of whom face significant health disparities including access to healthcare. Although previous studies have reported greater vaccine uptake in women compared to men, national-level estimates of influenza vaccine uptake among transgender and non-binary people are unknown. This study aims to characterize differences in influenza vaccine uptake by gender identity and examine associations between vaccination status and state-level gender equity policies. METHODS: We used cross-sectional data from adults participating in the 2015-2019 United States Behavioral Risk Factors Surveillance System surveys. Weighted prevalence differences (PDs) and associated confidence intervals (CIs) of being unvaccinated against influenza by self-reported gender identity were estimated using generalized linear regression models. RESULTS: Compared to cisgender women (unvaccinated prevalence = 57.3%), the prevalence of being unvaccinated was significantly higher among cisgender men (64.4%; PD = 7.0 per 100, 95% CI: 6.7-7.4), transgender women (65.4%; PD = 8.1 per 100, 95% CI 4.0-12.2), transgender men (64.6%; PD = 7.3 per 100, 95% CI: 2.7-11.8), and gender non-conforming individuals (64.6%; PD = 7.2 per 100, 95% CI: 1.3-13.2). This pattern was similar among individuals living in states with protective versus restrictive gender equity policies. CONCLUSIONS: Our results identified a disparity in influenza vaccine uptake among individuals across the gender spectrum. To improve vaccine equity, future research should explore barriers to and facilitators of vaccine uptake by gender identity, which could inform policies and health promotion interventions to improve uptake co-designed and implemented with the transgender and non-binary communities.

BACKGROUND: The association between vaginal washing and HIV risk may be mediated by vaginal washing-associated changes in vaginal microbiota. METHODS: Data from a cohort of HIV-negative US and Kenyan women enrolled in the Preventing Vaginal Infections trial were analyzed. Vaginal fluid samples and vaginal washing data were collected every 2 months for 12 months. Bacterial relative abundances were measured by broad-range 16S rRNA gene polymerase chain reaction with next generation sequencing. Generalized estimating equations were used to evaluate the association between vaginal washing and i) the Shannon Diversity Index (SDI); and ii) mean change in percent bacterial relative abundances, with application of a 10% false discovery rate (FDR). RESULTS: Participants (N = 111) contributed 93/630 (14.8%) vaginal washing visits. Mean SDI was 0.74 points higher (95% CI 0.35, 1.14; p < 0.001) at washing visits among US participants (N = 26). Vaginal washing was not associated with SDI in Kenyan participants (N = 85). There were no associations between vaginal washing and vaginal bacterial relative abundances after applying the FDR. CONCLUSIONS: The discordant results in Kenyan versus US women suggests the link between vaginal washing and sub-optimal vaginal microbiota may be context specific. Vaginal microbial shifts may not fully explain the association between vaginal washing and HIV acquisition.

Several studies have compared metagenome inference performance in different human body sites; however, none specifically reported on the vaginal microbiome. Findings from other body sites cannot easily be generalized to the vaginal microbiome due to unique features of vaginal microbial ecology, and investigators seeking to use metagenome inference in vaginal microbiome research are "flying blind" with respect to potential bias these methods may introduce into analyses. We compared the performance of PICRUSt2 and Tax4Fun2 using paired 16S rRNA gene amplicon sequencing and whole-metagenome sequencing data from vaginal samples from 72 pregnant individuals enrolled in the Pregnancy, Infection, and Nutrition (PIN) cohort. Participants were selected from those with known birth outcomes and adequate 16S rRNA gene amplicon sequencing data in a case-control design. Cases experienced early preterm birth (<32 weeks of gestation), and controls experienced term birth (37 to 41 weeks of gestation). PICRUSt2 and Tax4Fun2 performed modestly overall (median Spearman correlation coefficients between observed and predicted KEGG ortholog [KO] relative abundances of 0.20 and 0.22, respectively). Both methods performed best among Lactobacillus crispatus-dominated vaginal microbiotas (median Spearman correlation coefficients of 0.24 and 0.25, respectively) and worst among Lactobacillus iners-dominated microbiotas (median Spearman correlation coefficients of 0.06 and 0.11, respectively). The same pattern was observed when evaluating correlations between univariable hypothesis test P values generated with observed and predicted metagenome data. Differential metagenome inference performance across vaginal microbiota community types can be considered differential measurement error, which often causes differential misclassification. As such, metagenome inference will introduce hard-to-predict bias (toward or away from the null) in vaginal microbiome research. IMPORTANCE Compared to taxonomic composition, the functional potential within a bacterial community is more relevant to establishing mechanistic understandings and causal relationships between the microbiome and health outcomes. Metagenome inference attempts to bridge the gap between 16S rRNA gene amplicon sequencing and whole-metagenome sequencing by predicting a microbiome's gene content based on its taxonomic composition and annotated genome sequences of its members. Metagenome inference methods have been evaluated primarily among gut samples, where they appear to perform fairly well. Here, we show that metagenome inference performance is markedly worse for the vaginal microbiome and that performance varies across common vaginal microbiome community types. Because these community types are associated with sexual and reproductive outcomes, differential metagenome inference performance will bias vaginal microbiome studies, obscuring relationships of interest. Results from such studies should be interpreted with substantial caution and the understanding that they may over- or underestimate associations with metagenome content.

ABSTRACT: Although Lactobacillus crispatus -dominated vaginal microbiotas are thought to protect against bacterial vaginosis (BV) and sexually transmitted infections, the role of Lactobacillus iners -dominated microbiotas is less clear. To better understand the impact of L. iners on common cervicovaginal infections, we conducted systematic reviews of the associations between L. iners compared with L. crispatus and 8 outcomes: Chlamydia trachomatis (Ct), BV, human papillomavirus, cervical dysplasia, human immunodeficiency virus, genital herpes, Trichomonas vaginalis , and Neisseria gonorrhoeae . On April 30, 2021, we searched PubMed, Embase, Cochrane Library, and Web of Science for epidemiologic studies of reproductive-age, nonpregnant, cisgender women that used marker gene sequencing to characterize vaginal microbiota composition and presented an effect estimate for the association between L. iners , compared with L. crispatus , and outcomes of interest. For outcomes with ≥3 eligible results presenting the same form of effect estimate, we conducted random-effects meta-analysis. The review protocol was registered prospectively (PROSPERO CRD42020214775). Six Ct studies were included in meta-analysis, which showed L. iners -dominated microbiotas were associated with 3.4-fold higher odds of Ct compared with L. crispatus -dominated microbiotas (95% confidence interval, 2.1-5.4). Three BV studies were included in meta-analysis, which indicated L. iners -dominated microbiotas were associated with 2.1-fold higher prevalence of BV compared with L. crispatus -dominated microbiotas (95% confidence interval, 0.9-4.9). Evidence was too sparse to perform meta-analysis for the remaining outcomes. L. iners -dominated vaginal microbiotas may be suboptimal compared with L. crispatus -dominated microbiotas for BV and Ct. These reviews highlight evidence gaps regarding the remaining outcomes and opportunities to improve epidemiologic rigor in vaginal microbiome science.

OBJECTIVES: Bacterial vaginosis-associated bacterium 2 (BVAB2), Mageeibacillus indolicus and Sneathia spp are highly predictive of bacterial vaginosis (BV) in cisgender women. They have been associated with non-gonococcal urethritis (NGU) in cisgender men in some but not all populations. We evaluated this association in a cross-sectional study of cisgender men who have sex with women only (MSW). METHODS: MSW without gonorrhoea attending a sexual health clinic (SHC) from 2014 to 2018 completed a computer-assisted self-interview, clinical interview and examination. NGU was defined as ≥5 polymorphonuclear leucocytes/high-power field in urethral exudates plus either urethral symptoms or visible discharge. Urine was tested for Chlamydia trachomatis and Mycoplasma genitalium using Aptima (Hologic) and for BVAB2, M. indolicus, Sneathia spp, Trichomonas vaginalis, Ureaplasma urealyticum, Haemophilus influenzae, herpes simplex virus and adenovirus using quantitative PCR. RESULTS: Of 317 MSW age 17-71, 67 (21.1%) had Sneathia spp, 36 (11.4%) had BVAB2, and 17 (5.4%) had M. indolicus at enrolment. Having ≥3 partners in the past 2 months was the only characteristic that was more common among MSW with than those without these bacteria (BVAB2: 47% vs 23%, M. indolicus: 53% vs 24%, Sneathia spp: 42% vs 22%; p≤0.03 for all). One-hundred seventeen men (37%) were diagnosed with NGU at enrolment. There was no significant association of BVAB2, M. indolicus or Sneathia spp with NGU (adjusted OR=0.59, 95% CI 0.14 to 2.43; aOR=3.40, 95% CI 0.68 to 17.06; aOR=0.46, 95% CI 0.16 to 1.27). Of 109 MSW with monthly samples, 34 (31.2%) had one of the bacteria at one or more follow-up visits, 22 of which were co-colonised with >1. Median persistence over 6 months did not differ significantly (BVAB2=30.5 days, IQR=28-87; M. indolicus=87 days, IQR=60-126; Sneathia spp=70 days, IQR=30-135; p≥0.20 for each comparison). CONCLUSIONS: Neither BVAB2, M. indolicus nor Sneathia spp were associated with increased risk of prevalent NGU in MSW attending an SHC.

Research suggests that women's experience of intimate partner violence (IPV) is associated with poor engagement in HIV care and treatment. However, most studies have been cross-sectional and conducted in North America. We examined the association between physical IPV and HIV care outcomes in a prospective cohort study of women living with HIV (WLHIV) in Malawi, South Africa, Uganda, and Zimbabwe. At enrollment, 15% of the 351 participants self-reported physical IPV. IPV experience was not associated with time to first engagement in HIV care or the proportion virally suppressed after 6 months on ART. Women reporting physical IPV were less likely to initiate ART within 6 months of becoming eligible (adjusted RR 0.74, 95% CI 0.53-1.03). IPV screening is critical to identify survivors and link them to appropriate services. However, addressing IPV may not increase engagement in HIV care or viral load suppression among WLHIV in sub-Saharan Africa.

BACKGROUND: Many Plasmodium infections in endemic regions exist at densities below the limit of detection of standard diagnostic tools. These infections threaten control efforts and may impact vaccine and therapeutic drug studies. Simple, cost-effective methods are needed to study the natural history of asymptomatic submicroscopic parasitaemia. Self-collected dried blood spots (DBS) analysed using pooled and individual quantitative reverse transcription polymerase chain reaction (qRT-PCR) provide such a solution. Here, the feasibility and acceptability of daily at-home DBS collections for qRT-PCR was studied to better understand low-density infections. METHODS: Rapid diagnostic test (RDT)-negative individuals in Katakwi District, northeastern Uganda, were recruited between April and May 2021. Venous blood samples and clinic-collected DBS were taken at enrollment and at four weekly clinic visits. Participants were trained in DBS collection and asked to collect six DBS weekly between clinic visits. Opinions about the collection process were solicited using daily Diary Cards and a Likert scale survey at the final study visit. Venous blood and DBS were analysed by Plasmodium 18S rRNA qRT-PCR. The number of participants completing the study, total DBS collected, and opinions of the process were analysed to determine compliance and acceptability. The human internal control mRNA and Plasmodium 18S rRNA were evaluated for at-home vs. clinic-collected DBS and venous blood to assess quality and accuracy of at-home collected samples. RESULTS: One-hundred two adults and 29 children were enrolled, and 95 and 26 completed the study, respectively. Three individuals withdrew due to pain or inconvenience of procedures. Overall, 96% of participants collected ≥ 16 of 24 at-home DBS, and 87% of DBS contained ≥ 40 µL of blood. The procedure was well tolerated and viewed favourably by participants. At-home collected DBS were acceptable for qRT-PCR and showed less than a one qRT-PCR cycle threshold shift in the human control mRNA compared to clinic-collected DBS. Correlation between Plasmodium falciparum 18S rRNA from paired whole blood and DBS was high (R = 0.93). CONCLUSIONS: At-home DBS collection is a feasible, acceptable, and robust method to obtain blood to evaluate the natural history of low-density Plasmodium infections by qRT-PCR.

There is growing acknowledgement of the legacy of White supremacy and racism in the discipline of epidemiology. Our department in the University of Washington School of Public Health undertook a systematic effort to begin addressing institutionalized racism and inclusive teaching in our courses. In July 2020, we introduced a new tool (the "Course Development Plan" (CDP)) to advance our curriculum. The CDP includes 2 components: 1) a guideline document that provides strategies on how to modify curricula and classroom teaching to incorporate antiracism and principles of equity, diversity, and inclusion (EDI); and 2) a structured worksheet for instructors to share EDI and antiracism practices they already incorporate and practices they plan to incorporate into their classes. Worksheets for each class are submitted prior to the beginning of the quarter and are reviewed by a peer faculty member and at least 1 epidemiology student; reviewers provide written feedback on the CDP worksheet. Further evaluation to assess the impact of the CDP process on classroom climate is ongoing. In this commentary, we discuss our department's efforts, the challenges we faced, and our hopes for next steps.

BACKGROUND: Data on contraceptive use among women with bacterial sexually transmitted infections (STIs) are sparse, despite this population's high risk for unplanned pregnancy. METHODS: This cross-sectional study included 1623 cisgender women recently diagnosed with a bacterial STI who completed a public health Partner Services interview between January 2017 and December 2019 in King County, WA, USA. Contraceptive methods were categorized as: (1) highly or moderately effective and (2) least effective or no method. Poisson regression models were used to assess associations between individual characteristics and contraceptive method. RESULTS: Almost two thirds of the women (62.6%) reported using highly or moderately effective contraception, with 30.3% of women using long-acting contraception (LARC). More than one in three women (37.4%) reported using least effective methods or no method. Black women were less likely to report using a highly or moderately effective method compared to White women (aRR 0.58, 95% CI 0.43-0.80) and women with private insurance were more likely to report using a highly or moderately effective method compared to those with public insurance (aRR 1.67, 95% CI 1.28-2.19). CONCLUSIONS: Given that many women with bacterial STIs are not desiring pregnancy, this study highlights the need for additional reproductive health services for women with recent STI diagnoses.

Background: Bacterial colonization and associations with bacterial vaginosis (BV) signs and symptoms (Amsel criteria) may vary between populations. We assessed relationships between vaginal bacteria and Amsel criteria among two populations. Methods: Kenyan participants from the placebo arm of the Preventing Vaginal Infections (PVI) trial and participants from a Seattle-based cross-sectional BV study were included. Amsel criteria were recorded at study visits, and the vaginal microbiota was characterized using 16S rRNA gene sequencing. Logistic regression models, accounting for repeat visits as appropriate, were fit to evaluate associations between bacterial relative abundance and each Amsel criterion. Results: Among 84 PVI participants (496 observations) and 220 Seattle participants, the prevalence of amine odor was 25% and 40%, clue cells 16% and 37%, vaginal discharge 10% and 52%, elevated vaginal pH 69% and 67%, and BV 13% and 44%, respectively. BV-associated bacterium 1 (BVAB1) was positively associated with all Amsel criteria in both populations. Eggerthella type 1, Fannyhessea (Atopobium) vaginae, Gardnerella spp., Sneathia amnii, and Sneathia sanguinegens were positively associated with all Amsel criteria in the Seattle study, and all but discharge in the PVI trial. Conclusions: Core vaginal bacteria are consistently associated with BV signs and symptoms across two distinct populations of women.

OBJECTIVE: Vaccine-preventable human papillomavirus (HPV) infection is common, especially in sub-Saharan Africa where HIV risk is also high. However, unlike other sexually transmitted infections (STIs), HPV's role in HIV acquisition is unclear. We evaluated this relationship using data from MTN-003, a clinical trial of HIV chemoprophylaxis among cisgender women in sub-Saharan Africa. DESIGN: A case-control study. METHODS: We matched 138 women who acquired HIV (cases) to 412 HIV-negative controls. Cervicovaginal swabs collected within 6 months before HIV seroconversion were tested for HPV DNA. We estimated the associations between carcinogenic (high-risk) and low-risk HPV types and types targeted by HPV vaccines and HIV acquisition, using conditional logistic regression models adjusted for time-varying sexual behaviors and other STIs. RESULTS: Mean age was 23 (±4) years. Any, high-risk and low-risk HPV was detected in 84, 74 and 66% of cases, and 65, 55 and 48% of controls. Infection with at least two HPV types was common in cases (67%) and controls (49%), as was infection with nonavalent vaccine-targeted types (60 and 42%). HIV acquisition increased with any [adjusted odds ratio (aOR) 2.5, 95% confidence interval (95% CI) 1.3-4.7], high-risk (aOR 2.6, 95% CI 1.5-4.6) and low-risk (aOR 1.8, 95% CI 1.1-2.9) HPV. Each additional type detected increased HIV risk by 20% (aOR 1.2, 95% CI 1.1-1.4). HIV acquisition was associated with HPV types targeted by the nonavalent (aOR 2.1, 95% CI 1.3-3.6) and quadrivalent vaccines (aOR 1.9, 95% CI 1.1-3.2). CONCLUSION: HPV infection is associated with HIV acquisition in sub-Saharan African women. In addition to preventing HPV-associated cancers, increasing HPV vaccination coverage could potentially reduce HIV incidence.

INTRODUCTION: We sought to describe how Latina immigrants living in King County coped with the pandemic, including their attitudes and behaviors related to COVID-19, and the impact of the pandemic on their mental health and wellbeing. METHOD: We conducted surveys by phone with adult Spanish-speaking Latina immigrants (n = 137) in the summer of 2020. RESULTS: Very few women had been infected with COVID-19, and 23% reported having been tested. Most frequent reasons for not being tested were not knowing where to go (14%), concerns over the cost (15%), and not wanting to know if they were infected (12%). Most participants had concerns about paying for housing (76%) and food (73%). Depression and anxiety symptoms were in the moderate range. Almost all participants were practicing recommended preventive behaviors. CONCLUSION: Although few participants had COVID-19 infection, the pandemic had significant impacts on their mental health and ability to meet basic needs.
