Self-reported Cannabis Use and Changes in Body Mass Index, CD4 T-Cell Counts, and HIV-1 RNA Suppression in Treated Persons with HIV.

Cannabis use is prevalent among HIV-positive persons, but evidence regarding the impact of cannabis in HIV-positive persons is limited. We conducted a retrospective cohort study of HIV-positive adults initiating their first antiretroviral therapy (ART) regimen. A dedicated intake form assessed self-reported cannabis use in the preceding 7 days at each visit. The relationships between time-varying cannabis use and body mass index (BMI), CD4+ T-cell count, and HIV-1 RNA levels were assessed using random effects models adjusted for age, sex, race, and other reported substance use. 4290 patient-visits from 2008 to 2011 were available from 1010 patients. Overall, there were no statistically significant differences in CD4+ T-cell count and BMI across multiple adjusted models using different measures of cannabis use (ever use during the study period, any use, and number of times used in the preceding 7 days). Cannabis use by all three measures was associated with greater odds of having a detectable viral load at a given visit than no reported use (OR 2.02, 1.72, and 1.08, respectively; all adjusted p < 0.05). Self-reported cannabis use was not associated with changes in BMI or CD4+ T-cell count in ART-naïve HIV-positive persons starting treatment. However, reported cannabis use by multiple categories was associated with having a detectable HIV-1 RNA during the study period. Associations between cannabis use, adherence, and HIV-related outcomes merit further study.

Trends and Disparities in Mortality and Progression to AIDS in the Highly Active Antiretroviral Therapy Era: Tennessee, 1996-2016.

Objectives. To use statewide surveillance data to examine trends and disparities in mortality and progression from HIV to AIDS comprehensively in Tennessee over the past 20 years.Methods. Individuals diagnosed with HIV in Tennessee from 1996 to 2016 were identified through the Tennessee Department of Health Enhanced HIV/AIDS Reporting System. Clinical AIDS and all-cause mortality were the outcomes. Cox regression yielded adjusted hazard ratios (AHRs) for death and competing risk regression yielded adjusted subhazard ratios (SHRs) for AIDS, with death as the competing event.Results. Individuals with a history of heterosexual contact (AHR = 1.20; 95% confidence interval [CI] = 1.12, 1.29) and injection drug use (AHR = 1.27; 95% CI = 1.18, 1.38) had increased hazards of death relative to those with a history of male-to-male sexual contact. Hazards of death were lower among White (AHR = 0.79; 95% CI = 0.73, 0.85) and Hispanic (AHR = 0.50; 95% CI = 0.40, 0.63) individuals than among Black individuals. Those with heterosexual contact (SHR = 1.20; 95% CI = 1.12, 1.29) and injection drug use (SHR = 1.27; 95% CI = 1.18, 1.38) had a greater risk of AIDS than those with male-to-male sexual contact. White individuals (SHR = 0.85; 95% CI = 0.81, 0.90) had a lower risk of AIDS than Black individuals, and female individuals (SHR = 0.84; 95% CI = 0.79, 0.90) had a lower risk than male individuals.Conclusions. The trends, disparities, and outcomes assessed in our study will inform HIV testing and care linkage program design and implementation in Tennessee.

Relationship of Stigma and Depression Among Newly HIV-Diagnosed Chinese Men Who Have Sex with Men.

Little is known about the relationship between HIV stigma and depression among newly diagnosed HIV-infected men who have sex with men (MSM). We measured HIV-related stigma and current depression using standard scales among 367 Chinese MSM who had been diagnosed very recently with HIV infection, analyzing key associations with multivariable ordinal logistic regression. Current depression prevalence was 36 %. Median scores for felt, vicarious, and internalized stigma were 17, 2, and 5, respectively, each on a 0-30 scale. A one-point increase in the total stigma score was associated with a 4 % increase in the odds of current depression [adjusted odds ratio (aOR) = 1.04, 95 % confidence interval (CI) 1.03-1.05]. Internalized stigma had the strongest association with depression (aOR = 1.09, 95 % CI 1.07-1.12). Effective interventions to address coping with HIV-related stigma immediately following HIV-diagnosis might help reduce depression, improve long-term mental health, and improve engagement in their care.

Daily Marijuana Use is Associated with Missed Clinic Appointments Among HIV-Infected Persons Engaged in HIV Care.

We assessed the association between marijuana use and retention in HIV care through a retrospective cohort study of patients engaged in care at a large HIV clinic in 2011 and 2012. Two different retention outcomes were assessed: not meeting the Institute of Medicine's (IOM) retention definition (≥2 provider visits ≥90 days apart in a calendar year) and no-show visits. Any marijuana use and frequency of marijuana use were obtained from a substance use screening questionnaire administered at each clinic visit. Modified Poisson regression was used to estimate risk ratios and 95% confidence intervals for the association between marijuana use and retention outcomes. Marijuana use was reported by 17% of 1791 patients and 21% were not retained (IOM definition). Marijuana use was not associated with the IOM retention outcome, but was associated with missing the next scheduled appointment. A non-linear dose-response was observed for frequency of marijuana use and missed visits, with daily users having the highest risk compared to non-users. Daily marijuana use had a negative impact on HIV clinic attendance. Further research is needed to elucidate the mechanisms by which marijuana use affects this outcome to inform targeted interventions.

Subjective Ratings of Fatigue and Vigor in Adults With Hearing Loss Are Driven by Perceived Hearing Difficulties Not Degree of Hearing Loss.

OBJECTIVES: Anecdotal reports and qualitative research suggests that fatigue is a common, but often overlooked, accompaniment of hearing loss which negatively affects quality of life. However, systematic research examining the relationship between hearing loss and fatigue is limited. In this study, the authors examined relationships between hearing loss and various domains of fatigue and vigor using standardized and validated measures. Relationships between subjective ratings of multidimensional fatigue and vigor and the social and emotional consequences of hearing loss were also explored. DESIGN: Subjective ratings of fatigue and vigor were assessed using the profile of mood states and the multidimensional fatigue symptom inventory-short form. To assess the social and emotional impact of hearing loss participants also completed, depending on their age, the hearing handicap inventory for the elderly or adults. Responses were obtained from 149 adults (mean age = 66.1 years, range 22 to 94 years), who had scheduled a hearing test and/or a hearing aid selection at the Vanderbilt Bill Wilkerson Center Audiology clinic. These data were used to explore relationships between audiometric and demographic (i.e., age and gender) factors, fatigue, and hearing handicap scores. RESULTS: Compared with normative data, adults seeking help for their hearing difficulties in this study reported significantly less vigor and more fatigue. Reports of severe vigor/fatigue problems (ratings exceeding normative means by ±1.5 standard deviations) were also increased in the study sample compared with that of normative data. Regression analyses, with adjustments for age and gender, revealed that the subjective percepts of fatigue, regardless of domain, and vigor were not strongly associated with degree of hearing loss. However, similar analyses controlling for age, gender, and degree of hearing loss showed a strong association between measures of fatigue and vigor (multidimensional fatigue symptom inventory-short form scores) and the social and emotional consequences of hearing loss (hearing handicap inventory for the elderly/adults scores). CONCLUSIONS: Adults seeking help for hearing difficulties are more likely to experience severe fatigue and vigor problems; surprisingly, this increased risk appears unrelated to degree of hearing loss. However, the negative psychosocial consequences of hearing loss are strongly associated with subjective ratings of fatigue, across all domains, and vigor. Additional research is needed to define the pathogenesis of hearing loss-related fatigue and to identify factors that may modulate and mediate (e.g., hearing aid or cochlear implant use) its impact.

High HIV prevalence and the internet as a source of HIV-related service information at a community-based organization in Peru: a cross-sectional study of men who have sex with men.

BACKGROUND: The HIV prevalence among men who have sex with men (MSM) in Peru (12.4 %) is 30 times higher than in the general adult population (0.4 %). It is critical for community-based organizations to understand how to provide HIV services to MSM while maximizing limited resources. This study describes the HIV prevalence and risk profiles of MSM seeking HIV services at a community-based organization in Lima, Peru. It then compares HIV prevalence between those who found out about the HIV services through different sources. METHODS: A cross-sectional study of MSM seeking HIV services at Epicentro Salud in Lima, Peru for the first time between April 2012 and October 2013. We compared HIV prevalence among MSM who found out about Epicentro via online sources of information (N = 419), those using in-person sources (friends, partners) (N = 907), and sex workers (N = 140) using multivariable logistic regression models. RESULTS: HIV prevalence was 18.3 % overall: 23.2 % among MSM using online sources, 19.3 % among sex workers, and 15.9 % among MSM using in-person sources. However, when compared to the in-person group, sexual risk behaviors were not statistically higher among MSM using online sources. For the sex worker group, some behaviors were more common, while others were less. After adjusting for confounders, the odds of having HIV was higher for the online group (Odds Ratio = 1.61; 95 % Confidence Interval: 1.19-2.18), but not for the sex worker group (OR = 1.12; 95 % CI: 0.68-1.86), compared to the in-person group. CONCLUSION: Internet-based promotion appears to successfully reach MSM at high risk of HIV in Peru. Outreach via this medium can facilitate HIV diagnosis, which is the critical first step in getting infected individuals into HIV care. For community-based organizations working in resource-limited settings, this may be an effective strategy for engaging a subset of high-risk persons in HIV care.

HIV stigma as a barrier to retention in HIV care at a general hospital in Lima, Peru: a case-control study.

HIV stigma as a barrier to retention in HIV care has not been well-studied outside the United States. We conducted a case-control study in Lima, Peru to examine this issue. Cases were out-of-care for ≥12 months (n = 66) and controls were recruited from patients in active care presenting for a clinic visit (n = 110). A previously validated HIV stigma scale with four domains was used. Associations between being out-of-care and each stigma domain were assessed using multivariable logistic regression. Stigma scores were highest for disclosure concerns. Modest associations were found for greater disclosure concerns (OR 1.16; 95 % CI 0.99, 1.36) and concerns with public attitudes (OR 1.20; 95 % CI 1.03, 1.40). Enacted stigma and negative self-image showed non-linear associations with being out-of-care that plateaued or declined, respectively, at higher levels of stigma. The threshold effect for enacted stigma warrants further exploration, while disclosure concerns may be especially amenable to intervention in this population.

Exploring genetic risk for catatonia in a genome wide association study and polygenic risk score analysis.

BACKGROUND: Catatonia is an under-recognized disorder characterized by psychomotor (increased, decreased, or abnormal) changes, affective symptoms, and disturbance of volition, which may arise in the setting of decompensated psychiatric or non-psychiatric medical disorders. Genetic studies of catatonia are limited, and to the best of our knowledge no prior genome wide association studies of catatonia have been performed to date. METHODS: First we performed a genome wide association study of catatonia regardless of etiology (psychiatric or non-psychiatric). Secondarily we evaluated whether there was an elevated genetic risk profile for predisposing psychiatric disorders (schizophrenia spectrum disorder, bipolar affective disorder, etc.) in patients with catatonia. We used a matched case control design and applied polygenic risk scores to evaluate for a shared polygenetic contribution to catatonia from common psychiatric phenotypes that show a high prevalence of catatonia in their decompensated states. RESULTS: Anxiety, bipolar affective disorder, schizophrenia spectrum disorder and cross disorder polygenic risk scores were significantly associated with catatonia case status in both unadjusted and adjusted logistic regression models for the European Ancestry set even after correcting for multiple comparisons. Depression, Alzheimer's, Autism Spectrum Disorder and Obsessive Disorder polygenic risk scores were not significantly associated with catatonia status in participants of European Ancestry. In the African Ancestry set, no psychiatric polygenic risk scores were significantly associated with catatonia status in either the unadjusted or adjusted regression models. CONCLUSIONS: Even after controlling for relevant covariates, anxiety, bipolar affective disorder, schizophrenia spectrum disorder and cross disorders were significantly associated with catatonia status suggesting that there might be a shared genetic risk for those disorders amongst patients with catatonia.

Impact of definitions of loss to follow-up on estimates of retention, disease progression, and mortality: application to an HIV program in Mozambique.

Patient retention is critical to the management of chronic diseases such as human immunodeficiency virus (HIV); hence, accurate measures of loss to follow-up (LTF) are important. Many different LTF definitions have been proposed. In a cohort of 9,692 HIV-infected patients initiating antiretroviral therapy in Mozambique from 2006 to 2011, we investigated the impact of the definition of LTF on estimated rates of LTF, acquired immunodeficiency syndrome (AIDS)-defining events, and death by applying 17 different definitions of LTF gleaned from HIV literature. We further investigated the impact of 4 specific components of the LTF definitions. Cumulative incidences of LTF and AIDS-defining events were estimated by treating death as a competing risk; Kaplan-Meier techniques and variations to account for informative censoring were used to estimate rates of mortality. Estimates of LTF 2 years after treatment initiation were high and varied substantially, from 22% to 84% depending on the LTF definition used. Estimates of 2-year mortality varied from 11% to 16%, and estimates of 2-year AIDS-defining events varied from 6% to 8%. As seen here, the choice of LTF definition can greatly affect study conclusions and program evaluations. Selection of LTF definitions should be based on the study outcome, available data on clinical encounters, and the patients' visit schedules; we suggest some general guidelines.

Active cocaine use is associated with lack of HIV-1 virologic suppression independent of nonadherence to antiretroviral therapy: use of a rapid screening tool during routine clinic visits.

Clarifying the relationship between illicit drug use and HIV-1 virologic suppression requires characterization of both illicit drug use activity and adherence to antiretroviral therapy (ART). We developed a rapid clinical questionnaire to assess prior 7-day illicit drug use and ART adherence in a cross-sectional study among 1777 HIV-infected persons in care. Of these, 76% were male, 35% were African-American, and 8% reported injection drug use as their probable route of HIV-1 infection. Questionnaire-reported frequencies of cocaine and marijuana use within the previous 7 days were 3.3% and 12.1%, respectively. Over three quarters (77.8%) of participants were on ART, of whom 69.7% had HIV-1 virologic suppression (HIV-1 RNA<48 copies/mL). Univariate analyses revealed that compared to no use, cocaine and marijuana use were both associated with missed ART doses (P<0.01). Multivariable logistic regression analysis adjusting for nonadherence demonstrated that cocaine use was independently associated with failing to achieve virologic suppression (adjusted odds ratio (aOR): 0.46; 95% confidence interval (95% CI): 0.22-0.98) but marijuana use was not (aOR: 1.08; 95% CI: 0.72-1.62). This result strengthens the evidence of a direct effect of cocaine on virologic control, independent of nonadherence to ART.

Waning of SARS-CoV-2 Seropositivity among Healthy Young Adults over Seven Months.

BACKGROUND: We conducted a longitudinal study to estimate immunity produced in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among university students over seven months. METHODS: All participants were attending a public university and resided in Pitt County, North Carolina. University students enrolled weekly for 10 weeks between 26 August 2020 and 28 October 2020, resulting in 136 young adults completing at least one study visit by 17 November 2020. Enrolled students completed an online survey and nasal swab collection at two-week intervals and monthly blood collection between 26 August 2020 and 31 March 2021. RESULTS: Amongst 695 serum samples tested during follow-up, the prevalence of a positive result for anti-nucleocapsid antibodies (N-IgG) was 9.78%. In 22 students with more than one positive N-IgG serum sample, 68.1% of the group lost persistence of N-IgG below the positive threshold over 140 days. Anti-spike IgG antibodies were significantly higher among 11 vaccinated compared to 10 unvaccinated. CONCLUSIONS: In healthy young adults, N-IgG wanes below the detectable threshold within five months. S-IgG titer remained consistently elevated months after infection, and significantly increased after vaccination.

Socio-demographic and AIDS-related factors associated with tuberculosis stigma in southern Thailand: a quantitative, cross-sectional study of stigma among patients with TB and healthy community members.

BACKGROUND: Tuberculosis (TB) remains one of the most important infectious diseases worldwide. A comprehensive approach towards disease control that addresses social factors including stigma is now advocated. Patients with TB report fears of isolation and rejection that may lead to delays in seeking care and could affect treatment adherence. Qualitative studies have identified socio-demographic, TB knowledge, and clinical determinants of TB stigma, but only one prior study has quantified these associations using formally developed and validated stigma scales. The purpose of this study was to measure TB stigma and identify factors associated with TB stigma among patients and healthy community members. METHODS: A cross-sectional study was performed in southern Thailand among two different groups of participants: 480 patients with TB and 300 healthy community members. Data were collected on socio-demographic characteristics, TB knowledge, and clinical factors. Scales measuring perceived TB stigma, experienced/felt TB stigma, and perceived AIDS stigma were administered to patients with TB. Community members responded to a community TB stigma and community AIDS stigma scale, which contained the same items as the perceived stigma scales given to patients. Stigma scores could range from zero to 30, 33, or 36 depending on the scale. Three separate multivariable linear regressions were performed among patients with TB (perceived and experience/felt stigma) and community members (community stigma) to determine which factors were associated with higher mean TB stigma scores. RESULTS: Only low level of education, belief that TB increases the chance of getting AIDS, and AIDS stigma were associated with higher TB stigma scores in all three analyses. Co-infection with HIV was associated with higher TB stigma among patients. All differences in mean stigma scores between index and referent levels of each factor were less than two points, except for incorrectly believing that TB increases the chance of getting AIDS (mean difference of 2.16; 95% CI: 1.38, 2.94) and knowing someone who died from TB (mean difference of 2.59; 95% CI: 0.96, 4.22). CONCLUSION: These results suggest that approaches addressing the dual TB/HIV epidemic may be needed to combat TB stigma and that simply correcting misconceptions about TB may have limited effects.

Masculinity, resources, and retention in care: South African men's behaviors and experiences while engaged in TB care and treatment.

RATIONALE: Globally, the prevalence of tuberculosis (TB) disease is significantly higher among men compared to women. This is compounded by men's poorer uptake of TB testing and treatment, and worse outcomes for smear conversion and successful treatment completion compared to women; in South Africa specifically, TB accounts for a large portion of sex-specific life expectancy differences. OBJECTIVE: To understand men's unique barriers to accessing care and their needs while engaged in TB treatment, we conducted a qualitative study with men currently in or who recently completed TB treatment to understand how social norms for masculinity influence resource access and health behaviors, and in turn affect their engagement in care. METHODS: We interviewed 31 men using a semi-structured protocol, with domains including: social network composition and support; TB illness; and testing, treatment, and clinical care experiences. Interviews were analyzed using a constant comparison approach to identify resources and how these are exchanged within men's social networks for TB care. RESULTS: We found that men's prioritizing of work ensured food security and maintenance of masculinity norms, but delayed seeking and engagement in care. Once in treatment, men found it difficult both to negotiate clinic hours and work schedules and to navigate clinic environments without being labeled as weak. To mitigate individual resource gaps and losses, men typically accessed women family members who provided key resources (e.g., food, money, and emotional encouragement). Masculine identification with fatherhood was a key motivator to remain engaged in TB care and treatment. Loss from care was facilitated by isolation and limited access to social network resources. CONCLUSION: To improve men's engagement in care and successful treatment outcomes, interventions that leverage their social networks and build upon existing resources should be strongly considered.

Quantification and correlates of tuberculosis stigma along the tuberculosis testing and treatment cascades in South Africa: a cross-sectional study.

BACKGROUND: South Africa has one of the world's worst tuberculosis (TB) (520 per 100 000 population) and TB-human immunodeficiency virus (HIV) epidemics (~ 56% TB/HIV co-infected). While individual- and system-level factors influencing progression along the TB cascade have been identified, the impact of stigma is underexplored and underappreciated. We conducted an exploratory study to 1) describe differences in perceived community-level TB stigma among community members, TB presumptives, and TB patients, and 2) identify factors associated with TB stigma levels among these groups. METHODS: A cross sectional study was conducted in November 2017 at public health care facilities in Buffalo City Metro (BCM) and Zululand health districts, South Africa. Community members, TB presumptives, and TB patients were recruited. Data were collected on sociodemographic characteristics, TB knowledge, health and clinical history, social support, and both HIV and TB stigma. A validated scale assessing perceived community TB stigma was used. Univariate and multivariate linear regression models were used to describe differences in perceived community TB stigma by participant type and to identify factors associated with TB stigma. RESULTS: We enrolled 397 participants. On a scale of zero to 24, the mean stigma score for TB presumptives (14.7 ± 4.4) was statistically higher than community members (13.6 ± 4.8) and TB patients (13.3 ± 5.1). Community members from Zululand (ß = 5.73; 95% CI 2.19, 9.72) had higher TB stigma compared to those from BCM. Previously having TB (ß = - 2.19; 95% CI - 4.37, 0.0064) was associated with reduced TB stigma among community members. Understanding the relationship between HIV and TB disease (ß = 2.48; 95% CI 0.020, 4.94), and having low social support (ß = - 0.077; 95% CI - 0.14, 0.010) were associated with increased TB stigma among TB presumptives. Among TB Patients, identifying as Black African (ß = - 2.90; 95% CI - 4.74, - 1.04) and knowing the correct causes of TB (ß = - 2.93; 95% CI - 4.92, - 0.94) were associated with decreased TB stigma, while understanding the relationship between HIV and TB disease (ß = 2.48; 95% CI 1.05, 3.90) and higher HIV stigma (ß = 0.32; 95% CI 0.21, 0.42) were associated with increased TB stigma. CONCLUSIONS: TB stigma interventions should be developed for TB presumptives, as stigma may increase initial-loss-to-follow up. Given that stigma may be driven by numerous factors throughout the TB cascade, adaptive stigma reduction interventions may be required.

Interpersonal reactivity index adaptation among expectant seroconcordant couples with HIV in Zambézia Province, Mozambique.

BACKGROUND: The ability to understand another's emotions and act appropriately, empathy, is an important mediator of relationship function and health intervention fidelity. We adapted the Interpersonal Reactivity Index (IRI) - an empathy scale - among seroconcordant expectant couples with HIV in the Homens para Saúde Mais (HoPS+) trial - a cluster randomized controlled trial assessing couple-based versus individual treatment on viral suppression - in Zambézia Province, Mozambique. METHODS: Using baseline data from 1332 HoPS+ trial participants (666 couples), an exploratory factor analysis assessed culturally relevant questions from the IRI. Because empathy is interdependent among couples, we validated the results of the exploratory factor analysis using a dyadic confirmatory factor analysis (CFA) with dyadic measurement invariance testing. Finally, we assessed the relationship between scores on our final scale and basic demographic characteristics (sex, age, education, and depression) using t-tests. RESULTS: We found two subscales: 1) a seven-item cognitive empathy subscale (Cronbach's alpha 0.78) and 2) a six-item affective empathy subscale (Cronbach's alpha 0.73). The dyadic CFA found acceptable model fit and metric invariance across partners (Comparative Fit Index (CFI) = 0.914, Tucker Lewis Index = 0.904, Root Mean Squared Error of Approximation = 0.056, ΔCFI = 0.011). We observed higher cognitive (p: 0.012) and affective (p: 0.049) empathy among males and higher cognitive (p: 0.031) and affective (p: 0.030) empathy among younger participants. More educated participants had higher affective empathy (p: 0.017) and depressed participants had higher cognitive empathy (p: < 0.001). This two-subscale, 13-item version of the IRI measures cognitive and affective empathy in HoPS+ trial participants and adults while accounting for the interdependent nature of empathy within partner dyads. CONCLUSIONS: This scale will allow us to assess the interplay between empathy and other psychometric constructs (stigma, social support, etc.) in the HoPS+ trial and how each relates to retention in HIV, adherence to treatment, and prevention of maternal to child HIV transmission. Furthermore, this scale can be adapted for other sub-Saharan African populations, which will allow researchers to better assess HIV-related intervention efficacy. TRIAL REGISTRATION: This study is within the context of the HoPS+ trial, registered at ClinicalTrials.gov as number NCT03149237 . Registered May 11, 2017.

Measuring child survival for the Millennium Development Goals in Africa: what have we learned and what more is needed to evaluate the Sustainable Development Goals?

Reducing child mortality is a key global health challenge. We examined reasons for greater or lesser success in meeting under-five mortality rate reductions, i.e. Millennium Development Goal #4, between 1990 and 2015 in Sub-Saharan Africa where child mortality remains high. We first examined factors associated with child mortality from all World Health Organization African Region nations during the Millennium Development Goal period. This analysis was followed by case studies of the facilitators and barriers to Millennium Development Goal #4 in four countries - Kenya, Liberia, Zambia, and Zimbabwe. Quantitative indicators, policy documents, and qualitative interviews and focus groups were collected from each country to examine factors within and across countries related to child mortality. We found familiar themes that highlighted the need for both specific services (e.g. primary care access, emergency obstetric and neonatal care) and general management (e.g. strong health governance and leadership, increasing community health workers, quality of care). We also identified methodological opportunities and challenges to assessing progress in child health, which can provide insights to similar efforts during the Sustainable Development Goal period. Specifically, it is important for countries to adapt general international goals and measurements to their national context, considering baseline mortality rates and health information systems, to develop country-specific goals. It will also be critical to develop more rigorous measurement tools and indicators to accurately characterize maternal, neonatal, and child health systems, particularly in the area of governance and leadership. Valuable lessons can be learned from Millennium Development Goal successes and failures, as well as how they are evaluated. As countries seek to lower child mortality further during the Sustainable Development Goal period, it will be necessary to prioritize and support countries in quantitative and qualitative data collection to assess and contextualize progress, identifying areas needing improvement.

Promoting progress in child survival across four African countries: the role of strong health governance and leadership in maternal, neonatal and child health.

Despite numerous international and national efforts, only 12 countries in the World Health Organization's African Region met the Millennium Development Goal #4 (MDG#4) to reduce under-five mortality by two-thirds by 2015. Given the variability across sub-Saharan Africa, a four-country study was undertaken to examine barriers and facilitators of child survival prior to 2015. Liberia and Zambia were chosen to represent countries making substantial progress towards MDG#4, while Kenya and Zimbabwe represented countries making less progress. Our individual case studies suggested that strong health governance and leadership (HGL) was a significant driver of the greater success in Liberia and Zambia compared with Kenya and Zimbabwe. To elucidate specific components of national HGL that may have substantially influenced the pace of reductions in child mortality, we conducted a cross-country analysis of national policies and strategies pertaining to maternal, neonatal and child health (MNCH) and qualitative interviews with individuals working in MNCH in each of the four study countries. The three aspects of HGL identified in this study which most consistently contributed to the different progress towards MDG#4 among the four study countries were (1) establishing child survival as a top national priority backed by a comprehensive policy and strategy framework and sufficient human, financial and material resources; (2) bringing together donors, strategic partners, health and non-health stakeholders and beneficiaries to collaborate in strategic planning, decision-making, resource-allocation and coordination of services; and (3) maintaining accountability through a 'monitor-review-act' approach to improve MNCH. Although child mortality in sub-Saharan Africa remains high, this comparative study suggests key health leadership and governance factors that can facilitate reduction of child mortality and may prove useful in tackling current Sustainable Development Goals.

HIV Rapid Diagnostic Test Inventories in Zambézia Province, Mozambique: A Tale of 2 Test Kits.

BACKGROUND: The first pillar of the UNAIDS 90-90-90 goal seeks to accurately identify persons living with HIV (PLHIV), a process that is predicated on facilities having the necessary HIV tests available to perform the task. In many rural settings, the identification of PLHIV is accomplished through a two-step process involving the sequential use of 2 separate rapid diagnostic tests (RDTs). Inadequate inventory of either test has ramifications for the success of HIV-related programs. The purpose of this study was to evaluate the inventory levels of HIV RDT kits at specific healthcare facilities in Zambézia province, Mozambique. METHODS: Using facility-level pharmacy stock surveillance data from October 2015 through September 2016, we assessed the inventory levels of HIV RDTs at 75 health facilities in 8 districts within Zambézia province, Mozambique. Using programmatically established categories (good, sufficient, threatened, or stockout), defined in conjunction with the provincial health authorities, descriptive statistics were performed to determine inventory control of HIV RDTs at the district and health facility levels. Monthly proportions of adequate (good + sufficient) inventory were calculated for each district to identify inventory trends over the evaluation period. To assess whether the proportion of inadequate stocks differed between RDT, a mixed-effects logistic regression was conducted, with inadequate inventory status as the outcome of interest. RESULTS: When viewed as a whole, the inventory of each test kit was reported as being at adequate levels more than 89% of the time across the 75 facilities. However, disaggregated analysis revealed significant variability in the inventory levels of HIV RDTs at the district level. Specifically, the districts of Inhassunge, Namacurra, and Pebane reported inadequate inventory levels (threatened + stockout), of one or both test kits, for more than 10% of the study period. In addition, a disparity between inventory levels of each test kit was identified, with the odds of reporting inadequate inventory levels of the confirmatory test (Uni-Gold™) being approximately 1.8-fold greater than the initial test (Determine™) (odds ratio: 1.82, 95% CI: 1.40-2.38). CONCLUSION: As Test and Treat programs evolve, a significant emphasis should be placed on the "test" component of the strategy, beginning with assurances that health facilities have the adequate inventory of RDT necessary to meet the needs of their community. As national policy-makers rely predominantly on data from the upstream arm of the supply chain, it is unlikely the disparity between inventory levels of HIV RDTs identified at individual districts and specific health facilities would have been recognized. Moving forward, our findings point to a need for (1) renewed efforts reinforcing appropriate downstream forecasting of essential medicines and diagnostic tests in general and for Uni-Gold™ test kits specifically, and (2) simple metrics that may be routinely collected at all health facilities and which may then easily and quickly flow upstream so that policy-makers may optimally allocate resources.

Extrapulmonary tuberculosis, human immunodeficiency virus, and foreign birth in North Carolina, 1993 - 2006.

BACKGROUND: The proportion of extrapulmonary tuberculosis (EPTB) reported in the United States has been gradually increasing. HIV infection and foreign birth are increasingly associated with tuberculosis and understanding their effect on the clinical presentation of tuberculosis is important. METHODS: Case-control study of 6,124 persons with tuberculosis reported to the North Carolina Division of Public health from January 1, 1993 to December 31, 2006. Multivariate logistic regression was used to obtain adjusted odds ratios measuring the associations of foreign birth region and US born race/ethnicity, by HIV status, with EPTB. RESULTS: Among all patients with tuberculosis, 1,366 (22.3%) had EPTB, 563 (9.2%) were HIV co-infected, and 1,299 (21.2%) were foreign born. Among HIV negative patients, EPTB was associated with being foreign born (adjusted ORs 1.36 to 5.09, depending on region of birth) and with being US born, Black/African American (OR 1.84; 95% CI 1.42, 2.39). Among HIV infected patients, EPTB was associated with being US born, Black/African American (OR 2.60; 95% CI 1.83, 3.71) and with foreign birth in the Americas (OR 5.12; 95% CI 2.84, 9.23). CONCLUSION: Foreign born tuberculosis cases were more likely to have EPTB than US born tuberculosis cases, even in the absence of HIV infection. Increasing proportions of foreign born and HIV-attributable tuberculosis cases in the United States will likely result in a sustained burden of EPTB. Further research is needed to explore why the occurrence and type of EPTB differs by region of birth and whether host genetic and/or bacterial variation can explain these differences in EPTB.

Factors influencing rapid progress in child health in post-conflict Liberia: a mixed methods country case study on progress in child survival, 2000-2013.

OBJECTIVES: Only 12 countries in the WHO's African region met Millennium Development Goal 4 (MDG 4) to reduce under-five mortality by two-thirds by 2015. Given the variability across the African region, a four-country mixed methods study was undertaken to examine barriers and facilitators of child survival prior to 2015. Liberia was selected for an in-depth case study due to its success in reducing under-five mortality by 73% and thus successfully meeting MDG 4. Liberia's success was particularly notable given the civil war that ended in 2003. We examined some factors contributing to their reductions in under-five mortality. DESIGN: A case study mixed methods approach drawing on data from quantitative indicators, national documents and qualitative interviews was used to describe factors that enabled Liberia to rebuild their maternal, neonatal and child health (MNCH) programmes and reduce under-five mortality following the country's civil war. SETTING: The interviews were conducted in Monrovia (Montserrado County) and the areas in and around Gbarnga, Liberia (Bong County, North Central region). PARTICIPANTS: Key informant interviews were conducted with Ministry of Health officials, donor organisations, community-based organisations involved in MNCH and healthcare workers. Focus group discussions were conducted with women who have experience accessing MNCH services. RESULTS: Three prominent factors contributed to the reduction in under-five mortality: national prioritisation of MNCH after the civil war; implementation of integrated packages of services that expanded access to key interventions and promoted intersectoral collaborations; and use of outreach campaigns, community health workers and trained traditional midwives to expand access to care and improve referrals. CONCLUSIONS: Although Liberia experiences continued challenges related to limited resources, Liberia's effective strategies and rapid progress may provide insights for reducing under-five mortality in other post-conflict settings.
