    Abstract Background: Death certificate (DC) errors are common. At our institution, all deaths have a preliminary death certificate (PDC) written by a clinician and then revised by a pathologist prior to the clinician signing the final death certificate (FDC). In autopsy cases, the FDC is signed by the pathologist who performs the autopsy.
    Methods: A total of 100 in-hospital deaths (50 with autopsy and 50 without) occurred in 2020 were arbitrarily selected from a tertiary care center. All PDCs and FDCs were compared to identify/classify errors as major (incorrect cause of death (COD) or significant contributing factors) or minor (abbreviations, inappropriate non-essential contributing factors, immediate/intermediate COD errors). Frequency of PDC errors was compared by autopsy status, duration of hospital stay and PDC author.
    Results: Ninety percent of cases had at least one PDC error and 39% had a major error. Major errors were more common in autopsy cases (50% versus 28%, P = 0.035), although minor/overall errors were not. Error rates did not significantly differ for the other variables assessed.
    Conclusions: There is significance of having a pathologist review and revise DCs before they are signed. The increased frequency in major errors in cases with autopsy suggests that autopsy findings provided additional information to elucidate COD.

    Abstract The memory B-cell pool in an immune individual is more heterogeneous than previously recognized. The different types of memory B cells likely play distinct roles in tuning the secondary immune response because they differ in their potential to generate plasmablasts, which secrete antibodies, or germinal center (GC) cells, which generate new and higher affinity memory cells. We propose that the production of plasmablasts or GC cells by a memory B cell is controlled by its state of differentiation and the amount and affinity of antigen-specific antibodies present in the individual in which it resides.

    Abstract Background: The primary barrier to curing HIV infection is the pool of intact HIV proviruses integrated into host cell DNA throughout the bodies of people living with HIV (PLHIV), called the HIV reservoir. Reservoir size is impacted by the duration of HIV infection, delay in starting antiretroviral therapy (ART), and breakthrough viremia during ART. The leading infectious cause of death worldwide for PLHIV is TB, but we don't know how TB impacts the HIV reservoir.
    Methods: We designed a case-control study to compare HIV provirus-containing CD4 in PLHIV with vs. without a history of active TB disease. Study participants in the pilot and confirmatory cohort were enrolled at GHESKIO Centers in Port au Prince, Haiti. Intact and non-intact proviral DNA were quantified using droplet digital PCR of PBMC-derived CD4 cells. For a subset, Th1 and Th2 cytokines were assayed in plasma. Kruskal-Wallis tests were used to compare medians with tobit regression for censoring.
    Results: In the pilot cohort, we found that PLHIV with history of active pulmonary TB (n=20) had higher intact provirus than PLHIV without history of active TB (n=47) (794 vs 117 copies per million CD4, respectively; p<0.0001). In the confirmatory cohort, the quantity of intact provirus was higher in the TB group (n=13) compared with the non-TB group (n=18) (median 102 vs. 0 intact provirus per million CD4, respectively p=0.03). Additionally, we found that the frequencies of CD4+ T cells with any detectable proviral fragment was directly proportional to the levels of IL1B (p= 0.0025) and IL2 (p=0.0002).
    Conclusions: This is the first assessment of HIV provirus using IPDA in a clinical cohort from a resource limited setting, and the finding of larger reservoir in PLHIV with history of TB has significant implications for our understanding of TB-HIV coinfection and HIV cure efforts in TB-endemic settings.

    Abstract This retrospective case-control study examined the prevalence of HTLV-I and its association with tuberculosis among urban clinic patients in Haiti. Prevalence of HTLV-I among tuberculosis cases was 2.1% and among controls was 2.4%. Prevalence of HLTV-I was higher in females than males (odds ratio [OR] 2.45, P = 0.020). HTLV-I prevalence in those ≥ 50 years was 8.4% compared with 1.3% in those < 50 (OR 6.74, P < 0.001). We found no association between HTLV-I and tuberculosis in this population.

    Background: The World Health Organization recommends initiating same-day ART while tuberculosis testing is underway for patients with non-meningitic symptoms at HIV diagnosis, though safety data are limited. C-reactive protein (CRP) testing may improve tuberculosis risk stratification in this population.
    Methods: In this baseline analysis of 498 adults (>18 years) with tuberculosis symptoms at HIV diagnosis who were enrolled in a trial of rapid ART initiation in Haiti, we describe test characteristics of varying CRP thresholds in the diagnosis of TB. We also assessed predictors of high CRP (≥3 mg/dL) using generalized linear models.
    Results: Eighty-seven (17.5%) patients were diagnosed with baseline TB. The median CRP was 33.0 mg/L (IQR: 5.1, 85.5) in those with TB, and 2.6 mg/L (IQR: 0.8, 11.7) in those without TB. As the CRP threshold increased from ≥1 mg/L to ≥10 mg/L, the positive predictive value for TB increased from 22.4% to 35.4%, and negative predictive value decreased from 96.9% to 92.3%. With CRP thresholds varying from <1 to <10 mg/L, a range from 25.5% to 64.9% of the cohort would have been eligible for same-day ART, and 0.8% to 5.0% would have untreated TB at ART initiation.
    Conclusions: CRP concentrations can be used to improve TB risk stratification, facilitating same-day decisions about ART initiation. Depending on the CRP threshold, one-quarter to two-thirds of patients could be eligible for same-day ART, with a reduction of 3-fold to 20-fold in the proportion with untreated TB, compared with a strategy of same-day ART while awaiting TB test results.

    Abstract Introduction: Common mental disorders (CMDs) are highly prevalent among people with HIV. Integrating mental healthcare into HIV care may improve mental health and HIV treatment outcomes. We describe the reported availability of screening and treatment for depression, anxiety and post-traumatic stress disorder (PTSD) at global HIV treatment centres participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) Consortium in 2020 and changes in availability at sites in low- or middle-income countries (LMICs) between 2016/2017 and 2020.
    Methods: In 2020, 238 sites contributing individual-level data to the IeDEA Consortium and in 2016/2017 a stratified random sample of IeDEA sites in LMICs were eligible to participate in site surveys on the availability of screening and treatment for CMDs. We assessed trends over time for 68 sites across 27 LMICs that participated in both surveys.
    Results: Among the 238 sites eligible to participate in the 2020 site survey, 227 (95%) participated, and mental health screening and treatment data were available for 223 (98%) sites across 41 countries. A total of 95 sites across 29 LMICs completed the 2016/2017 survey. In 2020, 68% of sites were in urban settings, and 77% were in LMICs. Overall, 50%, 14% and 12% of sites reported screening with a validated instrument for depression, anxiety and PTSD, respectively. Screening plus treatment in the form of counselling was available for depression, anxiety and PTSD at 46%, 13% and 11% of sites, respectively. Screening plus treatment in the form of medication was available for depression, anxiety and PTSD at 36%, 11% and 8% of sites, respectively. Among sites that participated in both surveys, screening for depression was more commonly available in 2020 than 2016/2017 (75% vs. 59%, respectively, p = 0.048).
    Conclusions: Reported availability of screening for depression increased among this group of IeDEA sites in LMICs between 2016/2017 and 2020. However, substantial gaps persist in the availability of mental healthcare at HIV treatment sites across global settings, particularly in resource-constrained settings. Implementation of sustainable strategies to integrate mental health services into HIV care is needed.

    Abstract Background: Hypertension (HTN) is the leading cardiovascular disease (CVD) risk factor in Haiti and is likely driven by poverty-related social and dietary factors. Salt consumption in Haiti is hypothesized to be high but has never been rigorously quantified.
    Methods: We used spot urine samples from a subset of participants in the population-based Haiti Cardiovascular Disease Cohort to estimate population mean daily sodium intake. We compared three previously validated formulas for estimating dietary sodium intake using urine sodium, urine creatinine, age, sex, height, and weight. We explored the association between dietary sodium intake and blood pressure, stratified by age group.
    Results: A total of 1,240 participants had spot urine samples. Median age was 38 years (range 18-93), and 48% were female. The mean dietary sodium intake was 3.5-5.0 g/day across the three estimation methods, with 94.2%-97.9% of participants consuming above the World Health Organization (WHO) recommended maximum of 2 g/day of sodium. Among young adults aged 18-29, increasing salt intake from the lowest quartile of consumption (<3.73 g/day) to the highest quartile (>5.88 g/day) was associated with a mean 8.71 mmHg higher systolic blood pressure (SBP) (95% confidence interval: 3.35, 14.07; p = 0.001). An association was not seen in older age groups. Among participants under age 40, those with SBP ≥120 mmHg consumed 0.5 g/day more sodium than those with SBP <120 mmHg (95% confidence interval: 0.08, 0.69; p = 0.012).
    Conclusions: Nine out of 10 Haitian adults in our study population consumed more than the WHO recommended maximum for daily sodium intake. In young adults, higher sodium consumption was associated with higher SBP. This represents an inflection point for increased HTN risk early in the life course and points to dietary salt intake as a potential modifiable risk factor for primordial and primary CVD prevention in young adults.

    Abstract When exposed to antigens, naïve B cells differentiate into different types of effector cells: antibody-producing plasma cells, germinal center cells, or memory cells. Whether an individual naïve B cell can produce all of these different cell fates remains unclear. Using a limiting dilution approach, we found that many individual naïve B cells produced only one type of effector cell subset, whereas others produced all subsets. The capacity to differentiate into multiple subsets was a characteristic of clonal populations that divided many times and resisted apoptosis, but was independent of isotype switching. Antigen receptor affinity also influenced effector cell differentiation. These findings suggest that diverse effector cell types arise in the primary immune response as a result of heterogeneity in responses by individual naïve B cells.

    Abstract We determined the antigen binding activity of convalescent plasma units from 47 individuals with a history of non-severe COVID-19 using three clinical diagnostic serology assays (Beckman, DiaSorin, and Roche) with different SARS-CoV-2 targets. We compared these results with functional neutralization activity using a fluorescent reporter strain of SARS-CoV-2 in a microwell assay. This revealed positive correlations of varying strength (Spearman r = 0.37-0.52) between binding and neutralization. Donors age 48-75 had the highest neutralization activity. Units in the highest tertile of binding activity for each assay were enriched (75-82%) for those with the highest levels of neutralization.
