RESUMEN

Introduction: In sub-Saharan Africa, migrants are more likely to be HIV seropositive and viremic than non-migrants. However, little is known about HIV prevalence and viremia in non-migrants living in households with in- or out-migration events. We compared HIV outcomes in non-migrating persons in households with and without migration events using data from the Rakai Community Cohort Study (RCCS), an open population-based cohort in Uganda. Methods: We analyzed RCCS survey data from one survey round collected between August 2016 and May 2018 from non-migrating participants aged 15-49. Migrant households were classified as those reporting ≥1 member moving into or out of the household since the prior survey. A validated rapid test algorithm determined HIV serostatus. HIV viremia was defined as >1,000 copies/mL. Modified Poisson regression was used to estimate associations between household migration and HIV outcomes, with results reported as adjusted prevalence ratios (adjPR) with 95% confidence intervals (95%CI). Analyses were stratified by gender, direction of migration (into/out of the household), and relationship between non-migrants and migrants (e.g., spouse). Results: There were 14,599 non-migrants (7,654, 52% women) identified in 9,299 households. 4,415 (30%) lived in a household with ≥1 recent migrant; of these, 972(22%) had migrant spouses, 1,102(25%) migrant children, and 875(20%) migrant siblings. Overall, HIV prevalence and viremia did not differ between non-migrants in migrant and non-migrant households. However, in stratified analyses, non-migrant women with migrant spouses were significantly more likely to be HIV seropositive compared to non-migrant women with non-migrant spouses (adjPR:1.44, 95%CI:1.21-1.71). Conversely, non-migrant mothers living with HIV who had migrant children were less likely to be viremic (adjPR:0.34, 95%CI:0.13-0.86). Among non-migrant men living with HIV, spousal migration was associated with a non-significant increased risk of viremia (adjPR:1.37, 95%CI:0.94-1.99). Associations did not typically differ for migration into or out of the household. Conclusions: Household migration was associated with HIV outcomes for certain non-migrants, suggesting that the context of household migration influences the observed association with HIV outcomes. In particular, non-migrating women with migrating spouses were more likely to have substantially higher HIV burden. Non-migrants with migrant spouses may benefit from additional support when accessing HIV services.

RESUMEN

BACKGROUND: Elevated HIV-associated mortality persists, despite a notable decline with the expansion of antiretroviral therapy (ART). In South Africa, the relative majority of deaths occur in health facilities, providing an opportunity to track decedent characteristics. SETTING: We analyzed data from 14,870 adult patients who died between 2008 and 2018 at Klerksdorp/Tshepong Hospital Complex in South Africa. METHODS: Recorded data included demographics, causes of death, HIV status, ART, and tuberculosis (TB) history. We present summary statistics and results from linear, log-binomial, and multinomial regressions to quantify changes over time. RESULTS: Over the study period, the median age of decedents with HIV in the hospital increased from 39.3 to 43.4 years, and there was a switch to male predominance (46%-54%). Those who died at a younger age (<40 years) remained more likely to be HIV-positive than the older age group, despite the overall proportion of HIV-positivity decreasing over time. The proportion of decedents with HIV ever started on ART increased from 21% to 67%. The proportion of HIV patients dying from TB and AIDS-defining illnesses decreased from 31% to 22%. CONCLUSIONS: We noted a shift in deaths over time to more men and older individuals, whereas the burden of HIV was heaviest on the younger age groups. Advanced HIV disease remained an important cause of mortality. We also observed an increase in less-traditional opportunistic illnesses among those with HIV, including malignancy, cardiovascular disease, and kidney disease. The high proportion of patients on ART who died prematurely requires further research and interventions.

RESUMEN

BACKGROUND: The World Health Organization (WHO) recommends systematic symptom screening for tuberculosis (TB). However, TB prevalence surveys suggest that this strategy does not identify millions of TB patients, globally. Undiagnosed or delayed diagnosis of TB contribute to TB transmission and exacerbate morbidity and mortality. We conducted a cluster-randomized trial of large urban and rural primary healthcare clinics in 3 provinces of South Africa to evaluate whether a novel intervention of targeted universal testing for TB (TUTT) in high-risk groups diagnosed more patients with TB per month compared to current standard of care (SoC) symptom-directed TB testing. METHODS AND FINDINGS: Sixty-two clinics were randomized; with initiation of the intervention clinics over 6 months from March 2019. The study was prematurely stopped in March 2020 due to clinics restricting access to patients, and then a week later due to the Coronavirus Disease 2019 (COVID-19) national lockdown; by then, we had accrued a similar number of TB diagnoses to that of the power estimates and permanently stopped the trial. In intervention clinics, attendees living with HIV, those self-reporting a recent close contact with TB, or a prior episode of TB were all offered a sputum test for TB, irrespective of whether they reported symptoms of TB. We analyzed data abstracted from the national public sector laboratory database using Poisson regression models and compared the mean number of TB patients diagnosed per clinic per month between the study arms. Intervention clinics diagnosed 6,777 patients with TB, 20.7 patients with TB per clinic month (95% CI 16.7, 24.8) versus 6,750, 18.8 patients with TB per clinic month (95% CI 15.3, 22.2) in control clinics during study months. A direct comparison, adjusting for province and clinic TB case volume strata, did not show a significant difference in the number of TB cases between the 2 arms, incidence rate ratio (IRR) 1.14 (95% CI 0.94, 1.38, p = 0.46). However, prespecified difference-in-differences analyses showed that while the rate of TB diagnoses in control clinics decreased over time, intervention clinics had a 17% relative increase in TB patients diagnosed per month compared to the prior year, interaction IRR 1.17 (95% CI 1.14, 1.19, p < 0.001). Trial limitations were the premature stop due to COVID-19 lockdowns and the absence of between-arm comparisons of initiation and outcomes of TB treatment in those diagnosed with TB. CONCLUSIONS: Our trial suggests that the implementation of TUTT in these 3 groups at extreme risk of TB identified more TB patients than SoC and could assist in reducing undiagnosed TB patients in settings of high TB prevalence.

RESUMEN

BACKGROUND: We report the yield of targeted universal tuberculosis (TB) testing of clinic attendees in high-risk groups. METHODS: Clinic attendees in primary healthcare facilities in South Africa with one of the following risk factors underwent sputum testing for TB: human immunodeficiency virus (HIV), contact with a TB patient in the past year, and having had TB in the past 2 years. A single sample was collected for Xpert-Ultra (Xpert) and culture. We report the proportion positive for Mycobacterium tuberculosis. Data were analyzed descriptively. The unadjusted clinical and demographic factors' relative risk of TB detected by culture or Xpert were calculated and concordance between Xpert and culture is described. RESULTS: A total of 30 513 participants had a TB test result. Median age was 39 years, and 11 553 (38%) were men. The majority (n = 21734, 71%) had HIV, 12 492 (41%) reported close contact with a TB patient, and 1573 (5%) reported prior TB. Overall, 8.3% were positive for M. tuberculosis by culture and/or Xpert compared with 6.0% with trace-positive results excluded. In asymptomatic participants, the yield was 6.7% and 10.1% in symptomatic participants (with trace-positives excluded). Only 10% of trace-positive results were culture-positive. We found that 55% of clinic attendees with a sputum result positive for M. tuberculosis did not have a positive TB symptom screen. CONCLUSIONS: A high proportion of clinic attendees with specific risk factors (HIV, close TB contact, history of TB) test positive for M. tuberculosis when universal testing is implemented.

RESUMEN

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a complex cardiomyopathy with autosomal dominant inheritance and age-related incomplete penetrance, characterized by a high risk of sudden cardiac death. Recent professional consensus guidelines recommend clinical cardiac lifelong serial screening for at-risk family members refined only by age, but family genotype might influence necessary screening. Although numerous studies report prevalence of disease and arrhythmia in family members and explore predictors of penetrance and arrhythmic risk, a systematic review consolidating this evidence is lacking. METHODS: We searched Medline (PubMed), Embase, The Cochrane Library, and Web of Science for studies that reported prevalence of (1) diagnosis of ARVC per 2010 Task Force Criteria and/or (2) sustained ventricular arrhythmias (VA) in at least 10 family members of definite patients with ARVC. RESULTS: We identified 41 studies, including 36 that reported diagnosis by Task Force Criteria and 22 VA. Meta-analysis of 1359 family members, from 13 unique cohorts showed an average prevalence estimate of 25% for diagnosis as per Task Force Criteria (95% CI, 0.15-0.35, I2=96.44%). Overall prevalence of VA among gene-positive family members was 18% (95% CI, 0.13-0.23, I2=33.25%) in 7 independent studies (n=597). Family genotype was a significant risk factor for diagnosis of both ARVC (odds ratio, 6.91 [95% CI, 1.27-37.70]; P=0.0005) and VA (odds ratio, 13.62 [95% CI, 0.91-204.13]; P=0.06). Male gender was not associated with disease prevalence (odds ratio, 1.18 [95% CI, 0.72-1.95]; P=0.42) or VA (odds ratio, 0.81 [95% CI, 0.51-1.29]; P=0.91). CONCLUSIONS: The prevalence of ARVC and VA in at-risk family members differs significantly based on family genotype. Although recent recommendations provide a guideline based only on age, we propose screening every 1 to 2 years for gene-positive family members and every 3 to 5 years for first-degree relatives of gene-elusive cases, as long as they are asymptomatic and not athletes.

RESUMEN

BACKGROUND: Providing incentives to screen close contacts for tuberculosis (TB) is an alternative to household-based contact investigation. We aimed to characterize patients and contexts where this incentive-based strategy might be preferred. METHODS: This is a secondary analysis of a cluster randomized trial of TB contact investigation in Limpopo District, South Africa, conducted between 2016 and 2020. Twenty-eight clinics were randomly allocated to household-based vs incentive-based contact investigation. In the incentive-based arm, index participants and contacts received transport reimbursement and incentives for TB screening and microbiological diagnosis of contacts. We estimated differences in mean number of contacts per index participant with household-based vs incentive-based contact investigation overall and within subgroups of index participants. RESULTS: A total of 3776 contacts (1903 in the incentive-based and 1873 in the household-based arm) were referred by 2501 index participants. A higher proportion of contacts in the incentive-based than household-based arm were adults (72% vs 59%), reported chronic TB symptoms (25% vs 16%) or ever smoking (23% vs 11%). Index participants who walked or bicycled to a clinic referred 1.03 more contacts per index (95% confidence interval [CI], .48 to 1.57) through incentive-based than household-based investigation. Index participants living with >5 household members referred 0.48 more contacts per index (95% CI, .03 to .94) through household-based than incentive-based investigation. CONCLUSIONS: Relative to household-based investigation, incentive-based investigation identifies contacts likely at higher risk for active TB. Incentive-based investigation may be more appropriate for index participants who can easily access clinics, versus household-based investigation for patients with large households.

RESUMEN

BACKGROUND: Opioid overdose is preventable and reversible. To target overdose prevention training and naloxone distribution, it is important to understand characteristics of those people who use drugs most likely to witness an overdose. In this paper we report the proportion and characteristics of women who use heroin that have witnessed an opioid overdose in Dar es Salaam, Tanzania. METHODS: We conducted a cross-sectional survey with 200 women who use heroin. We fitted unadjusted and adjusted logistic regression models with witnessing an opioid overdose as the dependent variable and sociodemographic and drug use-related variables as independent variables. RESULTS: The majority of participants (85%) reported having ever witnessed an opioid overdose. Age (adjusted Odds Ratio [aOR] = 1.09; 95% CI: 1.02-1.12), having ever attempted to stop heroin use (aOR = 11.27; 95% CI: 2.25-56.46), history of arrest (aOR = 3.75; 95% CI: 1.32-10.63), and spending time daily in places where people use drugs (aOR = 3.72; 95% CI: 1.43-9.64) were found to be independently associated with ever witnessing an overdose. CONCLUSIONS: Findings suggest the need for expanded access to naloxone to lay people and community and peer-based overdose prevention training in Tanzania, including the distribution of naloxone in settings with high drug use.

RESUMEN

BACKGROUND: As opioid overdoses and deaths increase globally, little is known about these dimensions in Sub-Saharan Africa. In this paper, we explore factors associated with opioid overdose experiences among a sample of women who use opioids in Dar es Salaam, Tanzania. METHODS: We conducted a cross-sectional survey with 200 women who use opioids in Dar es Salaam, Tanzania, recruited via respondent-driven sampling. We fitted unadjusted and adjusted log-binomial regression models with robust standard errors to examine associations between participant characteristics and reporting ever had an opioid overdose in terms of prevalence ratios. RESULTS: Thirty-four percent (n = 68) of participants reported having ever had an opioid overdose. In the final adjusted model, having ever attempted to stop using heroin (adj. PR = 1.46, 95% CI: 1.01-2.12), sleeping outside in the past 6 months (adj. PR = 1.93, 95% CI: 1.29-2.91), injecting drugs (adj. PR = 1.78, 95% CI: 1.19-2.66), alcohol use (adj. PR = 1.56, 95% CI: 1.09-2.23), and having moderately severe to severe depression (adj. PR = 3.10, 95% CI: 1.07-8.97) were all found to be significantly associated with having ever had an opioid overdose. CONCLUSIONS: We demonstrate factors associated with opioid overdose among women who use drugs in Tanzania that may not be addressed with injection-focused harm reduction efforts. Our findings suggest the need for overdose surveillance efforts and further work to characterize overdose risks in this context in order to design relevant, targeted interventions to prevent opioid overdose in sub-Saharan Africa.

RESUMEN

PURPOSE: To evaluate the relationship of circulating immune cells with recurrence and metabolic/lifestyle factors in patients with early-stage breast cancer. METHODS: Patients with early-stage breast cancer were identified from the electronic record and institutional registry. Lymphocyte and monocyte counts were obtained from blood samples at time of diagnosis prior to any chemotherapy. Correlations between lymphocyte and monocyte and recurrence were assessed in the entire cohort and among obese patients, those reporting alcohol consumption and smoking. Competing risk regression was used to analyze time to recurrence. RESULTS: A total of 950 patients with ≥ 5 years of follow-up were identified; 433 had complete data and were eligible for analysis. 293 (68%) had hormone receptor-positive breast cancer, 82 (19%) HER2 positive, and 53 (13%) triple negative. Patients in the highest quintile of lymphocytes compared to the lowest quintile had lower risk of recurrence (subhazard ratio (SHR) = 0.17, 95% CI [0.03-0.93], p = 0.041) while patients in the highest quintile of monocytes had lower risk for recurrence (SHR = 0.19, 95% CI [0.04, 0.92], p = 0.039). Higher monocytes were more strongly associated with lower recurrence among those reporting alcohol consumption (HR = 0.10, 95% CI [0.01, 0.91], p = 0.04). In obese patients, higher lymphocytes were associated with lower risk of recurrence (p = 0.046); in non-obese patients, higher monocytes were associated with lower risk of recurrence (p = 0.02). There were no correlations among patients who reported tobacco use. CONCLUSIONS: High lymphocyte and monocyte counts are associated with lower recurrence rate in early-stage breast cancer, particularly in obese patients and those reporting alcohol consumption.

RESUMEN

BACKGROUND: Many individuals at risk for HIV may be reached through active TB case finding interventions in areas with highly prevalent co-epidemics of TB/HIV. METHODS: We analyzed data from a cluster-randomized trial of 2 TB case finding strategies: facility-based screening and contact investigation of newly identified TB cases. In both arms, on-site rapid HIV testing was offered to all contacts older than 18 months who did not self-report HIV-positive status. Those who were HIV infected were referred appropriately. All contacts 15 years and older were included in this analysis. RESULTS: Among 2179 contacts identified, 50% (1092) accepted HIV testing and counselling, of whom 6.3% (68) tested HIV-positive. Contacts who were unemployed [adjusted prevalence ratio (aPR) 1.14, 95% confidence interval (CI): 1.04 to 1.25], had not been to a clinic (aPR 1.09, 95% CI: 1.02 to 1.18) or HIV tested (aPR 1.25, 95% CI: 1.14 to 1.39) 6 months before, and those reporting gastrointestinal symptoms (aPR 1.22, 95% CI: 0.98 to 1.52) and genitourinary symptoms (aPR 1.30, 95% CI: 1.17 to 1.45) were significantly associated with accepting HIV testing. Women [adjusted odds ratio (aOR) 2.19, 95% CI: 1.26 to 3.81], individuals with a past history of tuberculosis (aOR 1.96, 95% CI: 0.93 to 4.14), and those not HIV tested 6 months before (aOR 2.20, 95% CI: 1.28 to 3.79) were significantly associated with testing HIV-positive. CONCLUSION: Offering HIV testing in the context of active tuberculosis case finding represents an opportunity to identify a large proportion of previously undiagnosed individuals with HIV in a population that might otherwise not seek testing.

RESUMEN

Daratumumab in combination with lenalidomide-dexamethasone (D-Rd) recently received FDA approval for the treatment of transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). The present PEGASUS study compared progression-free survival (PFS) in patients treated with D-Rd in the MAIA trial and patients treated with common standard-of-care regimens from the Flatiron Health electronic health record-derived deidentified database, which has data from patients treated primarily at community-based oncology practices in the United States. Individual-level patient data from both data sources were used to perform an anchored indirect treatment comparison (ITC) of D-Rd to bortezomib-lenalidomide-dexamethasone (VRd) and bortezomib-dexamethasone (Vd); lenalidomide-dexamethasone (Rd) was the common anchor for the ITC. Hazard ratios (HRs) reflecting direct comparisons of PFS within MAIA (D-Rd vs Rd) and Flatiron Health (VRd vs Rd; Vd vs Rd) were used to make ITCs for D-Rd vs VRd and Vd, respectively. After application of MAIA inclusion/exclusion criteria and propensity-score weighting, the Flatiron Health patients resembled the MAIA trial population on measured baseline characteristics. Based on the direct comparison within MAIA, treatment with D-Rd was associated with a significantly lower risk of progression or death compared to Rd (HR 0.54; 95% CI 0.42, 0.71). Based on the ITCs, D-Rd was associated with a significantly lower risk of progression or death compared to VRd (HR 0.68; 95% CI 0.48, 0.98) and Vd (HR 0.48; 95% CI 0.33, 0.69). In the absence of head-to-head trials comparing D-Rd to VRd or Vd, the present ITC may help inform treatment selection in transplant-ineligible patients with NDMM.

RESUMEN

BACKGROUND: The South African national HIV plan recommends pre-exposure prophylaxis (PrEP) for transgender women, whose HIV prevalence estimates are as high as 25% in sub-Saharan Africa. The aim of this study was to explore PrEP awareness, uptake, and willingness, as well as associated barriers and facilitators, in order to inform PrEP implementation efforts with transgender women in South Africa. METHODS: Using a community-engaged, convergent parallel mixed methods design, trained local transgender women data collectors recruited 213 transgender women participants (aged >18 years, assigned male sex at birth, and identifying as a gender different from male), via network referral and word-of-mouth in Cape Town, East London, and Johannesburg. A subset of 36 transgender women also participated in qualitative in-depth interviews. Quantitative analyses included descriptive statistics and negative binomial regression models to assess correlates of PrEP willingness. Qualitative interviews were audio-recorded, transcribed verbatim, and coded. Thematic content analysis was used to identify key themes. Quantitative and qualitative data were integrated for interpretation. FINDINGS: Participants were recruited between June 1 and Nov 30, 2018. 57 (45%) of 127 HIV-negative participants were PrEP-aware and only 14 (11%) of 129 were currently taking PrEP. HIV-negative participants experiencing social (eg, violence, poverty) and interpersonal (eg, discrimination, low transgender women community connectedness) hardship reported PrEP awareness more frequently than HIV-negative transgender women who did not. Willingness to take PrEP was low, at 56 (55%) of 102, among HIV-negative participants who were not currently taking PrEP, and negatively associated with transgender women community connectedness (multivariable prevalence ratio 0·87; 95% CI 0·77-0·99). Barriers to PrEP included taking a daily pill, side-effects, and cost. Participants urged greater education and engagement of transgender women in PrEP implementation. INTERPRETATION: South Africa is poised to scale up PrEP services for transgender women. Dedicated transgender clinics are planned to provide comprehensive care, including PrEP, for transgender women. It is critical to ensure transgender women are aware of and have accurate information about PrEP, and that health-care sites are prepared to provide quality care for transgender women.

RESUMEN

BACKGROUND: Youth-led strategies remain untested in clinic-based programs to improve viral suppression (VS) and reduce stigma among HIV-positive adolescents and young adults (AYA) in sub-Saharan Africa. In response, Project YES! placed paid HIV-positive youth peer mentors (YPM) in four HIV clinics in Ndola, Zambia including a Children's Hospital (pediatric setting), an adult Hospital and two primary care facilities (adult settings). METHODS: A randomized controlled trial was conducted from December 2017 to February 2019. Consecutively recruited 15 to 24-year-olds were randomly assigned to an intervention arm with monthly YPM one-on-one and group sessions and optional caregiver support groups, or a usual care comparison arm. Survey data and blood samples were collected at baseline and at the six-month midline. Generalized estimating equation models evaluated the effect of study arm over time on VS, antiretroviral treatment (ART) adherence gap, and internalized stigma. RESULTS: Out of 276 randomized youth, 273 were included in the analysis (Intervention n = 137, Comparison n = 136). VS significantly improved in both arms (I:63.5% to 73.0%; C:63.7% to 71.3.0%) [OR:1.49, 95% CI:1.08, 2.07]. In a stratified analysis intervention (I:37.5% to 70.5%) versus the comparison (C:60.3% to 59.4%) participants from the pediatric clinic experienced a relative increase in the odds of VS by a factor of 4.7 [interaction term OR:4.66, 95% CI:1.84, 11.78]. There was no evidence of a study arm difference in VS among AYA in adult clinics, or in ART adherence gaps across clinics. Internalized stigma significantly reduced by a factor of 0.39 [interaction term OR:0.39, 95% CI:0.21,0.73] in the intervention (50.4% to 25.4%) relative to the comparison arm (45.2% to 39.7%). CONCLUSIONS: Project YES! engaged AYA, improving VS in the pediatric clinic and internalized stigma in the pediatric and adult clinics. Further research is needed to understand the intersection of VS and internalized stigma among AYA attending adult HIV clinics. TRIAL REGISTRATION: ClinicalTrials.gov NCT04115813.

RESUMEN

Animal source foods (ASF) provide nutrients essential to child growth and development yet remain infrequently consumed in rural Nepal. Agriculture and nutrition programs aim to increase ASF intake among children through small-scale animal husbandry projects. The relationship between livestock ownership and children's consumption of ASF, however, is not well established. This study examined associations between livestock ownership and the frequency with which Nepali children consume eggs, dairy, and meat. We analyzed longitudinal 7-day food frequency data from sentinel surveillance sites of the Policy and Science of Health, Agriculture and Nutrition (PoSHAN) study. Data consisted of surveys from 485 Nepali farming households conducted twice per year for two years (a total of 1449 surveys). We used negative binomial regression analysis to examine the association between the number of cattle, poultry, and meat animals (small livestock) owned and children's weekly dairy, egg, and meat intakes, respectively, adjusting for household expenditure on each food type, mother's education level, caste/ethnicity, agroecological region, season, and child age and sex. We calculated predicted marginal values based on model estimates. Children consumed dairy 1.4 (95% CI 1.1-2.0), 2.3 (1.7-3.0) and 3.0 (2.1-4.2) more times per week in households owning 1, 2-4 and >4 cattle, respectively, compared to children in households without cattle. Children consumed eggs 2.8 (2.1-3.7) more times per week in households owning 1 or 2 chickens compared to children in households without chickens. Child intake of meat was higher only in households owning more than seven meat animals. Children's intakes of dairy, eggs, and meat rose with household expenditure on these foods. Small-scale animal production may be an effective strategy for increasing children's consumption of eggs and dairy, but not meat. Increasing household ability to access ASF via purchasing appears to be an important approach for raising children's intakes of all three food types.

RESUMEN

BACKGROUND: Intimate partner violence (IPV), HIV and sexually transmitted infections (STI) can contribute to disparities in population health, depending on the individual, social and environmental factors characterizing a setting. To better understand the place-based determinants and patterns of these key interrelated public health problems in Uganda, we compared risk factors for IPV, HIV and STI in fishing, trading and agrarian communities in Rakai, Uganda by gender. METHOD: This study used cross-sectional data collected from 14,464 sexually active men (n = 6531) and women (n = 7933) as part of the Rakai Community Cohort Study, a population-based open cohort study of men and women aged 15-49 years. We used multilevel modified poisson regression models, which incorporated random intercepts for community and households. Factors associated with IPV, HIV and STI were assessed separately for men and women in fishing, trading and agrarian communities. RESULTS: A larger proportion of participants in the fishing communities than those in trading and agrarian communities were HIV positive, engaged in HIV risk behaviors, had STI symptoms and reported perpetration of or victimization by IPV. Female gender was a shared correlate of IPV, HIV and STI in the fishing communities. Engagement in multiple sexual relationships or partner's engagement in multiple relationships were shared correlates of IPV, and HIV in agrarian communities and IPV and STI in trading communities. CONCLUSION: Programs should target factors at multiple levels to reduce risk for syndemic conditions of HIV, STI and IPV in Rakai, Uganda particularly among men and women in fishing communities.

RESUMEN

BACKGROUND: There is a dearth of comparative effectiveness research examining the implementation of different strategies for active tuberculosis (TB) case finding, particularly in rural settings, which represent 60% of the population of sub-Saharan Africa. METHODS AND FINDINGS: We conducted a pragmatic, cluster-randomized comparative effectiveness trial of two TB case finding strategies (facility-based screening and contact tracing) in 56 public primary care clinics in two largely rural districts of Limpopo Province, South Africa. In the facility-based screening arm, sputum Xpert MTB/RIF was performed on all patients presenting (for any reason) with TB symptoms to 28 study clinics, and no contact tracing was performed. In the contact-tracing arm, contacts of patients with active TB were identified (via household tracing in 14 clinics and using small monetary incentives in the other 14 clinics), screened for TB symptoms, and offered Xpert MTB/RIF testing. The primary outcome was the number of newly identified patients with TB started on treatment. The analysis used multivariable Poisson regression adjusted for historical clinic-level TB case volumes and district. The trial was registered with ClinicalTrials.gov (NCT02808507). From July 18, 2017, to January 17, 2019, a total of 3,755 individuals started TB treatment across 56 study clinics in the 18-month period. Clinic characteristics and clinic-level averages of patient characteristics were similar across the two arms: 40/56 (71%) clinics were in a rural location, 2,136/3,655 (58%) patients were male, and 2,243 (61%) were HIV positive. The treatment initiation ratio comparing the yield of TB patients started on treatment in the facility-based arm compared to that from the contact-tracing arm was 1.04 (95% confidence interval [CI] 0.83-1.30, p = 0. 73). In the contact-tracing arm, 1,677 contacts of 788 new TB index patients were screened, yielding 12 new patients with TB. Prespecified subgroup analyses resulted in similar results, with estimated treatment initiation ratios of 0.96 (95% CI 0.64-1.27; p = 0.78) and 1.23 (95% CI 0.87-1.59; p = 0.29) among historically smaller and historically larger clinics, respectively. This ratio was 1.02 (95% CI 0.66-1.37; p = 0.93) and 1.08 (95% CI 0.74-1.42; p = 0.68) in the Vhembe and Waterberg districts, respectively. The estimated treatment initiation ratio was unchanged in sensitivity analyses excluding 24 records whose TB registration numbers could not be verified (1.03, 95% CI 0.82-1.29; p = 0.78) and excluding transfers-in (1.02, 95% CI 0.80-1.29; p = 0.71). Study limitations include the possibility of imbalance on cluster size owing to changes in catchment population over time and the inability to distinguish the independent effects of the two contact investigation strategies. CONCLUSIONS: Contact tracing based on symptom screening and Xpert MTB/RIF testing did not increase the rate of treatment initiation for TB relative to the less resource-intensive approach of facility-based screening in this rural sub-Saharan setting. TRIAL REGISTRATION: ClinicalTrials.gov NCT02808507.

RESUMEN

BACKGROUND: Studies have revealed associations between preceding short and long birth-to-birth or birth-to-pregnancy intervals and poor pregnancy outcomes. Most of these studies, however, have examined the effect of intervals that began with live births. Using data from Bangladesh, we examined the effect of inter-outcome intervals (IOI) starting with a non-live birth or neonatal death, on outcomes in the next pregnancy. Pregnancy spacing behaviors in rural northeast Bangladesh have changed little since 2004. METHODS: We analyzed pregnancy histories for married women aged 15-49 years who had outcomes between 2000 and 2006 in Sylhet, Bangladesh. We examined the effects of the preceding outcome and the IOI length on the risk of stillbirth, neonatal death and spontaneous abortion using multinomial logistic regression models. RESULTS: Data included 64,897 pregnancy outcomes from 33,495 mothers. Inter-outcome intervals of 27-50 months and live births were baseline comparators. Stillbirths followed by IOI's <=6 months, 7-14 months or overall <=14 months had increased risks for spontaneous abortion with adjusted relative risk ratios (aRRR) and 95% confidence intervals = 29.6 (8.09, 108.26), 1.84 (0.84, 4.02) and 2.53 (1.19, 5.36), respectively. Stillbirths followed by IOIs 7-14 months had aRRR 2.00 (1.39, 2.88) for stillbirths. Neonatal deaths followed by IOIs <=6 months had aRRR 28.2 (8.59, 92.63) for spontaneous abortion. Neonatal deaths followed by IOIs 7-14 and 15-26 months had aRRRs 3.08 (1.82, 5.22) and 2.32 (1.38, 3.91), respectively, for stillbirths; and aRRRs 2.81 (2.06, 3.84) and 1.70 (1.24, 3.84), respectively, for neonatal deaths. Spontaneous abortions followed by IOIs <=6 months and 7-14 months had, respectively, aRRRs 23.21 (10.34, 52.13) and 1.80 (0.98, 3.33) for spontaneous abortion. CONCLUSION: In rural northeast Bangladesh, short inter-outcome intervals after stillbirth, neonatal death and spontaneous abortion were associated with a high risk of a similar outcome in the next pregnancy. These findings are aligned with other studies from Bangladesh. Two studies from similar settings have found benefits of waiting six months before conceiving again, suggesting that incorporating this advice into programs should be considered. Further research is warranted to confirm these findings.

RESUMEN

BACKGROUND: The 2015 earthquake in Nepal caused massive damages and triggered relief activities to minimize human suffering. The post-earthquake nutrition and food security situation in the hardest hit areas remains uncertain. METHODS: Two national cross-sectional surveys were conducted in 2014 and 2016 among households (HH) with pre-school aged children or newly married women. Of the 21 village development committees (VDCs) included in this sample, 7 fell within "earthquake-affected" areas. This paper presents data from 982 HH, 1015 women, and 883 children from 2014 and 1056 HH, 1083 women, and 998 children from 2016 living in these areas, with longitudinal overlap of about 55%. Prevalence estimates and 95% confidence intervals were calculated, and logistic regression was used to calculate p-values, both using robust estimates of standard errors to account for clustering. RESULTS: From 2014 to 2016, child wasting (weight-for-height z score <-2) fell from 4.5% (95% CI 3.3%- 6.1%) to 2.1% (1.4%- 3.1%) and food insecurity (assessed using the household food insecurity access scale) dropped from 17.6% (11.7%- 25.6%) to 12.4% (6.9%- 21.2%). Child stunting prevalence remained similar at both time-points. Improvements were also evident in dietary diversity and breastfeeding indicators. CONCLUSIONS: Nutrition and food security conditions remained comparable or improved one year after the earthquake despite evidence of structural and other damage. Livelihood resilience to shocks and/or effective nutrition, food or health interventions may have helped buffer the impact on nutrition, although this hypothesis requires further exploration.

RESUMEN

BACKGROUND: Children's dietary patterns vary seasonally, particularly in subsistence agriculture settings like Nepal, but the seasonality of nutritious nonstaple food consumption is not well explored in the literature. OBJECTIVE: This study aimed to examine seasonal differences in children's consumption of provitamin A-rich fruit and vegetables, dairy, eggs, meat, and fish in Nepal's 3 agroecological zones, and to assess whether seasonal patterns vary by wealth and caste/ethnicity. METHODS: Multivariable negative binomial regression models were used to analyze dietary data from 7-d food-frequency questionnaires, producing coefficient estimates in the form of incidence rate ratios (IRRs). Data were collected 3 times per year for 2 y from children aged 6-72 mo in Nepal's mountains (n = 226), hills (n = 168), and plains (n = 225). RESULTS: There were significant seasonal differences in children's consumption of provitamin A-rich fruit and vegetables, dairy, meat, and fish that varied by agroecological zone. Adopting monsoon season as the referent for all comparisons, children in the mountains ate provitamin A-rich fruit and vegetables less frequently during the postmonsoon and winter seasons (IRRs: 0.5 and 0.7, respectively; both P < 0.004), whereas in the plains, children's consumption of these foods was lower only during the postmonsoon season (IRR: 0.2; P < 0.001). Children's dairy intake frequency increased during the winter in the mountains (IRR: 0.7; P < 0.004) and decreased during the winter in the hills (IRR: 1.5; P < 0.001). Only in the plains did children's meat and fish intakes vary seasonally, increasing during the postmonsoon season (IRR: 1.6; P < 0.004). Wealth and caste/ethnicity variability influenced children's consumption of each of these nutritious groups of foods, and moderated seasonal effects in some instances. CONCLUSIONS: Children's diets varied differently by season within each agroecological zone of Nepal and in some cases across socioeconomic groups, revealing the importance of taking a season- and location-specific approach to assessing diets and tailoring dietary strategies.
