Background

Homelessness increases the risk of tuberculosis (TB) disease and latent TB infection (LTBI), but persons experiencing homelessness often lack access to testing and treatment. We assessed the yield of TB testing and linkage to care for programs targeting homeless populations in the United States.

Methods

We conducted a comprehensive search of peer-reviewed and grey literature, adapting Cochrane systematic review methods. Two reviewers independently assessed study eligibility and abstracted key data on the testing to care cascade: number of persons reached, recruited for testing, tested for LTBI, with valid test results, referred to follow-up care, and initiating care. We used random effects to calculate pooled proportions and 95% confidence intervals (CI) of persons retained in each step via inverse-variance weighted meta-analysis, and cumulative proportions as products of adjacent step proportions.

Results

We identified 23 studies published between 1986 and 2014, conducted in 12 states and 15 cities. Among studies using tuberculin skin tests (TST) we found that 93.7% (CI 72.4-100%) of persons reached were recruited, 97.9% (89.3-100%) of those recruited had tests placed, 85.5% (78.6-91.3%) of those with tests placed returned for reading, 99.9% (99.6-100%) of those with tests read had valid results, and 24.7% (21.0-28.5%) with valid results tested positive. All persons testing positive were referred to follow-up care, and 99.8% attended at least one session of follow-up care. Heterogeneity was high for most pooled proportions. For a hypothetical cohort of 1000 persons experiencing homelessness reached by a targeted testing program using TST, an estimated 917 were tested, 194 were positive, and all of these initiated follow-up care.

Conclusions

Targeted TB testing of persons experiencing homelessness appears effective in detecting LTBI and connecting persons to care and potential treatment. Future evaluations should assess diagnostic use of interferon gamma release assays and completion of treatment, and costs of testing and treatment.

Background

Harmful alcohol use is a leading cause of morbidity and mortality in sub-Saharan Africa (sSA); however, the effects of non-pharmacological alcohol interventions in this region are unknown.

Design

A systematic review and meta-analysis of the available literature through 14 March 2019 was undertaken. Two authors extracted and reconciled relevant data and assessed risk of bias. Meta-analyses were conducted. The review protocol is registered on International Prospective Register of Systematic Reviews (PROSPERO) (CRD42019094509).

Setting

Studies conducted in sSA were eligible for inclusion.

Participants

Individuals participating in interventions aimed at reducing alcohol use.

Interventions

Randomized and non-randomized controlled trials testing non-pharmacological interventions (psychosocial and structural) on alcohol consumption in sSA.

Measurements

Eligible outcomes included the Alcohol Use Disorders Identification Test (AUDIT) scores; alcohol abstinence; measures of drinking quantity and frequency; and biomarkers of alcohol consumption.

Findings

Nineteen intervention trials (18 reports) testing psychosocial interventions (no structural interventions included), judged of moderate quality, were included in meta-analyses. A beneficial effect was identified for psychosocial interventions on alcohol abstinence at 3-6 months [odds ratio (OR) = 2.05, 95% confidence interval (CI) = 1.20-3.48, k = 5, n = 2312, I²  = 79%] and 12-60 months (OR = 1.91, 95% CI = 1.40-2.61, k = 6, n = 2737, I²  = 63%) follow-up. There were no statistically significant effects found for AUDIT score [2-3 months: mean differences (MD) = -1.13, 95% CI = -2.60 to 0.34, k = 6, n = 992, I²  = 85%; 6 months: MD = -0.83, 95% CI = -1.92 to 0.26, k = 6, n = 1081, I²  = 69%; 12 months: MD = -0.15, 95% CI = -1.66 to 1.36, k = 4; n = 677; I²  = 75%], drinks per drinking day (3 months: MD = -0.22, 95% CI = -2.51 to 2.07, k = 2, n = 359, I²  = 82%; 6-36 months: MD = -0.09, 95% CI = -0.49 to 0.30, k = 3, n = 1450, I²  = 60%) or percentage of drinking days (3 months: MD = -4.60, 95% = -21.14 to 11.94; k = 2; n = 361; I²  = 90%; 6-9 months: MD = 1.96, 95% CI = -6.54 to 10.46; k = 2; n = 818; I²  = 88%).

Conclusion

Psychosocial interventions show promise at increasing self-reported alcohol abstinence in sSA, but clinical, methodological and statistical heterogeneity across meta-analytical outcomes suggests that results should be interpreted with caution.

Background

Persons who experience homelessness remain at increased risk for three viral blood-borne infections: human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). We assessed the yield of testing and linkage to care programs targeting this population for these infections in the United States (US).

Methods

We searched PubMed, Embase, Web of Science, and Cochrane Central for peer-reviewed articles through August 27, 2020. Additionally, we searched the grey literature. Two individuals independently reviewed all relevant studies to check for eligibility and extracted data for each step in the care cascade. We used random-effects model to generate weighted pooled proportions to assess yield at each step. Cumulative proportions were calculated as products of adjacent-step pooled proportions. We quantitatively synthesized data from the studies that focused on non-drug injecting individuals.

Results

We identified 24 studies published between 1996-2019 conducted in 19 US states. Seventeen studies screened for HIV, 12 for HCV, and two screened for HBV. For HIV, 72% of approached were recruited, 64% had valid results, 4% tested positive, 2% were given results, and 1% were referred and attended follow-up. Of positives, 25% were referred to treatment and started care. For HCV, 69% of approached were recruited, 63% had valid results, 16% tested positive, 14% were given results, and 3% attended follow-up. Of positives, 30% were referred for treatment and 19% started care. The yield at each care cascade step differs widely by recruitment strategy (for example, for HIV: 71.6% recruited of reached under service-based with zero yield under healthcare facility-based and outreach).

Conclusions

A very large proportion of this population reached for HIV and HCV care were lost in the follow-up steps and never received treatment. Future programs should examine drop-out reasons and intervene to reduce health disparities in this population.

Background

Contact investigation is an important strategy for maintaining control of tuberculosis (TB) in the United States. However, testing and treatment outcomes specifically to foreign-born populations are poorly understood. We reviewed literature on testing and LTBI identified during contact investigations in foreign-born populations living in the US.

Methods

We conducted a comprehensive search of peer-reviewed and grey literature using Cochrane systematic review methods. We included studies with adult and adolescent populations that were at least 50% foreign-born. Pooled proportions and 95% confidence intervals (CIs) were calculated via inverse-variance weighted meta-analysis, and cumulative proportions were calculated as products of adjacent step proportions.

Results

We identified 22 studies published between 1997 and 2014 that included at least 50% foreign-born participants. From studies of predominantly (>90%) foreign-born populations, almost all identified contacts were recruited and had valid test results, and 54.8% (95% CI 45.1-62.5%) of contacts with valid test results tested positive. From studies of majority (50% to 90%) foreign-born populations, 78.4% (95% CI 78.0-78.9%) of identified contacts were recruited, 92.0% (95% CI 91.6-92.3%) of recruited contacts had valid test results, and 38.5% (95% CI 31.9%-44.2%) of persons with valid results tested positive. These proportions varied by test type in studies of predominantly foreign-born populations. For every 1000 contacts identified in predominantly foreign-born populations, we estimate that 535 (95% CI 438 to 625) will test positive, and 354 (95% CI 244 to 453) will complete LTBI treatment. For every 1000 contacts identified in majority foreign-born populations, these estimates are 276 (95% CI 230 to 318), and 134 (95% CI 44 to 264), respectively.

Conclusions

Contact investigation is a high yield activity for identifying and treating foreign-born persons with LTBI, but must be complemented by other tuberculosis control activities in order to achieve continued progress toward TB elimination.

Fishing communities in Uganda have high rates of excessive alcohol consumption and negative health outcomes related to alcohol consumption, such as HIV acquisition and transmission and intimate partner violence victimization and perpetration. Research lacks understanding of alcohol use in Ugandan fishing communities, underlying reasons for excessive drinking among fishermen or how their community perceives negative health outcomes linked to excessive alcohol consumption. This qualitative study was conducted among Ugandan fisherfolk to determine why excessive alcohol consumption has overtaken their communities. Through analyzing in-depth interviews and focus group discussions, reasons for drinking and community perceptions of drinking were explored using the Socio Ecological Model and the Time Perspective Theory. Interviews were coded into two content themes: social influences on drinking and using alcohol to cope with stress. Participants acknowledged links between excessive alcohol consumption and negative health outcomes within their families and communities. These findings highlight the need for alcohol-related reduction interventions that are sensitive to contextual factors and self-identified contributors to problematic alcohol use within individuals and their communities. Such interventions must consider the social, ecological and economic conditions within fishing sites, focusing not only on individual-level behavioral change but also challenging the underlying structures that foster excessive alcohol consumption.

Background

South African women experience high levels of alcohol use and HIV infection during the perinatal period. Oral pre-exposure prophylaxis (PrEP) is highly effective at reducing HIV risk. We examined associations between alcohol use and PrEP use during pregnancy and postpartum.

Methods

The PrEP in Pregnant and Postpartum women study is a prospective observational cohort of 1200 HIV-negative pregnant women enrolled at first antenatal care visit and followed through 12 months' postpartum in Cape Town, South Africa. The analytic sample comprised pregnant women who initiated PrEP at baseline and were not censored from study follow-up before 3-month follow-up. We examined associations between any or hazardous alcohol use (Alcohol Use Disorders Identification Test-Consumption score ≥3) in the year before pregnancy and PrEP continuation and adherence during pregnancy (self-report of missing <2 doses in past 7 days and biomarker-confirmed with tenofovir diphosphate in dried blood spots).

Results

Of 943 women on PrEP (median age of 26 years), 50% reported alcohol use before pregnancy, and 33% reported hazardous use. At 3-month follow-up, 58% of women were still using PrEP; 41% reported recent adherence, and 23% were biomarker-confirmed adherent. In multivariable models, hazardous alcohol use was associated with increased odds of continuing PrEP [adjusted odds ratio (aOR) = 1.54, 95% confidence interval (CI): 1.16-2.06], self-reported PrEP adherence (aOR = 1.41, 95% CI: 1.07-1.87), and biomarker-confirmed PrEP adherence (aOR = 1.35 95% CI: 0.98, 1.87). Associations were similar in models of any alcohol use and PrEP continuation/adherence.

Conclusions

Pregnant and postpartum women who reported recent alcohol use had increased odds of continuing to take PrEP, indicating that higher risk women may continue on oral PrEP.

Context

An estimated 21% of non-U.S.-born persons in the United States have a reactive tuberculin skin test (TST) and are at risk of progressing to TB disease. The effectiveness of strategies by healthcare facilities to improve targeted TB infection testing and linkage to care among this population is unclear.

Evidence acquisition

Following Cochrane guidelines, we searched several sources to identify studies that assessed strategies directed at healthcare providers and/or non-U.S.-born patients in U.S. healthcare facilities.

Evidence synthesis

Seven studies were eligible. In a randomized controlled trial (RCT), patients with reactive TST who received reminders for follow-up appointments were more likely to attend appointments (risk ratio, RR = 1.05, 95% confidence interval 1.00-1.10), but rates of return in a quasi-RCT study using patient reminders did not significantly differ between study arms (P = 0.520). Patient-provider language concordance in a retrospective cohort study did not increase provider referrals for testing (P = 0.121) or patient testing uptake (P = 0.159). Of three studies evaluating pre and post multifaceted interventions, two increased TB infection testing (from 0% to 77%, p < .001 and RR 2.28, 1.08-4.80) and one increased provider referrals for TST (RR 24.6, 3.5-174). In another pre-post study, electronic reminders to providers increased reading of TSTs (RR 2.84, 1.53-5.25), but only to 25%. All seven studies were at high risk of bias.

Conclusions

Multifaceted strategies targeting providers may improve targeted TB infection testing in non-U.S.-born populations visiting U.S. healthcare facilities; uncertainties exist due to low-quality evidence. Additional high-quality studies on this topic are needed.

Fishing communities in Uganda have high rates of excessive alcohol consumption and negative health outcomes related to alcohol consumption, such as HIV acquisition and transmission and intimate partner violence victimization and perpetration.

The syndemic relationship between harmful alcohol use, intimate partner violence (IPV), and HIV is well established across international settings. Less is known about how these health issues are perceived by women living with HIV (WLWH), who are disproportionately affected by these intertwined epidemics. A qualitative study was undertaken with 20 WLWH in Rakai, Uganda, to assess their perceptions of how these issues have affected their lives and their communities and to assess the acceptability of integrating a screening and brief intervention for alcohol use and IPV into HIV posttest counseling. Recommendations for intervention programming arising from the results are discussed.

Mental health disorders account for a heavy disease burden in Uganda. In order to provide culturally appropriate mental health prevention and treatment approaches, it is necessary to understand how mental health is conceptualized in the population. Three focus group discussions (FGDs) and 31 in-depth interviews (IDIs) were conducted with men and women aged 14 to 62 years residing in rural, urban, and semi-urban low-income communities in central and western Uganda to explore perceptions and knowledge of mental health. Interpretive thematic analysis was undertaken; results were organized through the lens of the mental health literacy framework. Environmental and societal stressors were identified as primary underlying causes of poor mental health. While participants recognized symptoms of poor mental health, gaps in mental health literacy also emerged. Mental health resources are needed in this setting and additional qualitative work assessing knowledge and attitudes toward mental health care seeking behavior can inform the development of acceptable integrated services.
