Abstract
Background: There is uncertainty about the actual burden of childhood TB in Uganda, but underestimation is acknowledged. We aimed at determining prevalence, factors associated with PTB among children attending PHC facilities in Kampala.
Methods: This was a cross-sectional study of 255 children, with presumed TB, attending six health facilities in Kampala, Uganda, in March 2015. Socio-demographic, clinical, and laboratory data were collected using a questionnaire. TB was diagnosed using “Desk Guide” algorithms. Sputum based on ZN/FM and/or Gene-Xpert. Logistic regression was used to assess associations with outcomes.
Results: Overall, prevalence of PTB 13.7 % (2.6 – 24.8). Among HIV-positive, the prevalence of PTB was 41.7%, while among malnourished children, 21.7% and contacts, 89.3%. The factors that influenced PTB included: tobacco smoker at home (OR =1.6, 95 % CI: 1.07 – 6.86), stunting (OR = 2.2, 95 % CI: 1.01 – 4.15). Only 5.3% of the smear-negative TB children and 81.3% of the smear-positive children were initiated on treatment within a month of diagnosis.
Conclusion: Clinical TB among children is underdiagnosed and undertreated. There is a need for more sensitive and specific diagnostic tests, need ways to disseminate and promote uptake of standardized clinical algorithms. Also, contact TB tracing should be strengthened so that such cases can be actively detected even at community level.

Abstract
BACKGROUND Economic vulnerability influences women engaged in commercial sex work (WESW) to further engage in sexual risk behaviors, as they often have multiple customers and engage in unprotected sex for financial gains. This study examined asset ownership's direct and indirect impact on sexual risk-taking behaviors among WESW in Southern Uganda, a very vulnerable group of women at high risk for contracting HIV and other STIs. METHODOLOGY We used baseline data from the Kyaterekera study, an NIH-funded study among WESW aged 18-55 across 19 HIV hotspots in Southern Uganda. Structural equation modeling was used to examine the direct, indirect, and total effects of assets-defined as ownership of physical and financial resources-on sexual risk-taking behaviors among WESW. RESULTS Results showed that asset ownership was associated with a decrease in depression (β = - 0.096 [95% CI - 0.191, - 0.001], p = 0.050) and increased access to medical care (β = 0.174 [95% CI 0.072, 0.275], p = 0.001).We also found that an increase in access to medical care was associated with decreased sexual risk-taking behaviors (β = - 0.107 [95% CI - 0.210, - 0.004], p = 0.041). We observed a specific indirect effect between assets and sexual risk-taking behaviors through access to medical care (β = - 0.019 [95% CI - 0.040, - 0.002], p = 0.05). Mediation contributed 31% of the total effects of asset ownership on sexual risk-taking behaviors. CONCLUSION To our knowledge, this is among the few studies to examine the impact of asset ownership on sexual risk-taking behaviors among WESW in Southern Uganda. Findings from this study indicate that increasing access to economic resources may reduce the risk of WESW engaging in unprotected sex for higher income, which limits the spread of HIV among this population. The results also indicate that asset ownership may allow women to access healthcare services.

Abstract
Children growing up in poverty are disproportionately affected by diseases, including HIV. In this study, we use data from Suubi+Adherence, a longitudinal randomized control trial (2012-2018) with 702 adolescents living with HIV (ALWHIV), to examine the effectiveness of a family-based multifaceted economic empowerment (EE) intervention in addressing economic instability and multidimensional poverty among ALWHIV in Southern Uganda. We constructed a Multidimensional Poverty Index of individual and household indicators, including health, assets, housing and family dynamics. We computed the proportion of multidimensionally poor children (H), estimated poverty intensity (A) and adjusted headcount ratio (M0). Using repeated measures at five-time points (baseline, years 1, 2, 3 and 4-post baseline) across two study arms: treatment (receiving the EE intervention) vs. control arm (not receiving EE), we find that both the incidence and proportion of multidimensional poverty decreased in the treatment arm vs. the control arm. Given that there is a direct link between economic instability and poor health outcomes, these findings are informative. They point to the potential for family EE interventions to decrease multidimensional poverty among vulnerable children, including ALWHIV, impacting their overall wellbeing and ability to meet their treatment needs and improve HIV care continuum outcomes.

Abstract
INTRODUCTION Women engaged in sex work (WESW) have an elevated risk of the human immunodeficiency virus (HIV) and sexually transmitted infections (STI). Estimates are three times higher than the general population. Understanding the predictors of HIV and STI among WESW is crucial in developing more focused HIV and STI prevention interventions among this population. The study examined the prevalence and predictors of HIV and STI among WESW in the Southern part of Uganda. METHODOLOGY Baseline data from the Kyaterekera study involving 542 WESW (ages 18-55) recruited from 19 HIV hotspots in the greater Masaka region in Uganda was utilized. HIV and STI prevalence was estimated using blood and vaginal fluid samples bioassay. Hierarchical regression models were used to determine the predictors of HIV and STI among WESW. RESULTS Of the total sample, 41% (n = 220) were found to be HIV positive; and 10.5% (n = 57) tested positive for at least one of the three STI (Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis) regardless of their HIV status. Older age (b = 0.09, 95%CI = 0.06, 0.13, p≤0.001), lower levels of education (b = -0.79, 95%CI = -1.46, -0.11, p≤0.05), fewer numbers of children in the household (b = -0.18, 95%CI = -0.36, -0.01), p≤0.05), location (i.e., fishing village (b = 0.51, 95%CI = 0.16, 0.85, p≤0.01) or small town (b = -0.60, 95%CI = -0.92, -0.28, p≤0.001)), drug use (b = 0.58, 95%CI = 0.076, 1.08, p≤0.05) and financial self-efficacy (b = 0.05, 95%CI = -0.10, 0.00, p≤0.05), were associated with the risk of HIV infections among WESW. Domestic violence attitudes (b = -0.24, 95%CI = -0.42, -0.07, p≤0.01) and financial distress (b = -0.07, 95%CI = -0.14, -0.004, p≤0.05) were associated with the risk of STI infection among WESW. CONCLUSION Study findings show a high prevalence of HIV among WESW compared to the general women population. Individual and family level, behavioural and economic factors were associated with increased HIV and STI infection among WESW. Therefore, there is a need for WESW focused HIV and STI risk reduction and economic empowerment interventions to reduce these burdens.

Abstract
INTRODUCTION Optimal antiretroviral therapy (ART) adherence is crucial for improved patient outcomes; however, ART adherence among adolescents living with HIV (ALHIV) is low. Also, the performance of various adherence measures among ALHIV is under contention. We monitored ART adherence and compared Self-report (SR) and Wisepill electronic monitoring (EM) performance in measuring ART adherence and predicting HIV viral suppression among ALHIV. METHODS Between January 2014 and December 2015, we recruited 702 ALHIV aged 10-16 years into our cluster-randomized controlled trial (2012-2018) in 39 clinics in Uganda. The intervention included a long-term savings child development account, four micro-enterprise workshops and 12 mentorship sessions. Using the entire sample, we performed multilevel logistic regression to predict monthly ART adherence trends for the first year of follow-up. Since it is possible that the intervention had different effects on SR and EM adherence, we used participants in the control arm only to compare adherence using SR and EM and to calculate their sensitivity and specificity in predicting viral suppression. RESULTS There was a significant decline in adherence for each month throughout the entire follow-up period regardless of the group assigned. Good ART adherence was measured at 79.2% (75.2-82.6%) and 97.0% (95.4-98.1%) using EM and SR, respectively. Overall, 64.3% (60.6-67.9%) had suppressed viral loads. The specificities for EM and SR in predicting viral non-suppression were 80.4% (73.6-85.7%) and 96.7% (93.3-98.4%), while the sensitivities were 22.9% (15.0-33.3%) and 1.8% (0.4-6.9%), respectively. The area under the curve was low for both EM and SR, at 53.6% (45.7-61.5%) and 56.2% (53.2-59.3%), respectively. There was high agreement (78%) between SR and EM in monitoring adherence. CONCLUSIONS Our findings highlighted the need for strategies for sustained optimal adherence. SR and EM measure adherence with a considerable agreement; however, neither is an accurate predictor of virological outcome. There is still a need for an acceptable, feasible and affordable method that predicts viral suppression among ALHIV.

Abstract
BACKGROUND Adolescents are lagging behind in the "third 95" objective of the Joint United Nations Program on HIV/AIDS requiring 95% of individuals on antiretroviral therapy (ART) to have viral load (VL) suppression. This study aimed to describe factors associated with viral non-suppression among adolescents in Mbale district, Uganda. METHODS We conducted a retrospective review of routinely collected HIV programme records. Data such as age, education, ART Regimen, ART duration, WHO Clinical stage, comorbidities, etc., were extracted from medical records for the period January 2018 to December 2018. Descriptive analysis was done for continuous variables using means and frequencies to describe study sample characteristics, and to determine the prevalence of outcome variables. We used logistic regression to assess factors associated with VL non-suppression among adolescents. RESULTS The analysis included 567 HIV-infected adolescents, with 300 (52.9%) aged between 13 to 15 years, 335 (59.1%) female, and mean age of 15.6 years (interquartile range [IQR] 13.5-17.8. VL non-suppression was 31.4% (178/567). Male sex (AOR = 1.78, 95% CI 1.06, 2.99; p < 0.01), age 16-19 years (AOR = 1.78, 95% CI 1.06, 2.99; p < 0.05), No formal education (AOR = 3.67, 95% CI 1.48-9.09; p < 0.01), primary education (AOR = 2.23, 95% CI 1.05-2.32; p < 0.01), ART duration of > 12 months to 5 years (AOR = 3.20, 95% CI 1.31-7.82; p < 0.05), ART duration > 5 years (AOR = 3.47, 95% CI 1.39- 8.66; p < 0.01), WHO Clinical Stage II (AOR = 0.48, 95% CI: 0.28, 0.82; p < 0.01), second-line ART regimen (AOR = 2.38, 95% CI 1.53-3.72; p < 0.001) and comorbidities (AOR = 3.28, 95% CI 1.20-9.00; p < 0.05) were significantly associated with viral non-suppression. CONCLUSIONS VL non-suppression among adolescents was almost comparable to the national average. VL non-suppression was associated with being male, age 16-19 years, education level, duration on ART therapy, WHO Clinical Staging II, second-line ART regimen, and presence of comorbidities. Adolescent-friendly strategies to improve VL suppression e.g. peer involvement, VL focal persons to identify and actively follow-up non-suppressed adolescents, patient education on VL suppression and demand creation for ART are needed, especially for newly-initiated adolescents and adolescents on ART for protracted periods, to foster attainment of the UNAIDS 95-95-95 targets.

Abstract
INTRODUCTION Achieving optimal adherence to antiretroviral therapy (ART) among adolescents living with HIV (ALWHIV) is challenging, especially in low-resource settings. To help accurately determine who is at risk of poor adherence, we developed and internally validated models comprising multi-level factors that can help to predict the individualized risk of poor adherence among ALWHIV in a resource-limited setting such as Uganda. METHODS We used data from a sample of 637 ALWHIV in Uganda who participated in a longitudinal study, "Suubi+Adherence" (2012 to 2018). The model was developed using the Least Absolute Shrinkage and Selection Operator (LASSO) penalized regression to select the best subset of multi-level predictors (individual, household, community or economic-related factors) of poor adherence in one year's time using 10-fold cross-validation. Seventeen potential predictors included in the model were assessed at 36 months of follow-up, whereas adherence was assessed at 48 months of follow-up. Model performance was evaluated using discrimination and calibration measures. RESULTS For the model predicting poor adherence, five of the 17 predictors (adherence history, adherence self-efficacy, family cohesion, child poverty and group assignment) were retained. Its ability to discriminate between individuals with and without poor adherence was acceptable; area under the curve (AUC) = 69.9; 95% CI: 62.7, 72.8. There was no evidence of possible areas of miscalibration (test statistic = 1.20; p = 0.273). The overall performance of the model was good. CONCLUSIONS Our findings support prediction modelling as a useful tool that can be leveraged to improve outcomes across the HIV care continuum. Utilizing information from multiple sources, the risk prediction score tool applied here can be refined further with the ultimate goal of being used in a screening tool by practitioners working with ALWHIV. Specifically, the tool could help identify and provide early interventions to adolescents at the highest risk of poor adherence and/or viral non-suppression. However, further fine-tuning and external validation may be required before wide-scale implementation.

Abstract
BACKGROUND Antiretroviral therapy (ART) adherence is a primary determinant of sustained viral suppression, HIV transmission risk, disease progression and death. The World Health Organization recommends that adherence support interventions be provided to people on ART, but implementation is suboptimal. We evaluated linkage to intensive adherence counselling (IAC) for persons on ART with detectable viral load (VL). METHODS Between January and December 2017, we conducted a retrospective chart review of HIV-positive persons on ART with detectable VL (> 1000 copies/ml), in Gomba district, rural Uganda. We abstracted records from eight HIV clinics; seven health center III's (facilities which provide basic preventive and curative care and are headed by clinical officers) and a health center IV (mini-hospital headed by a medical doctor). Linkage to IAC was defined as provision of IAC to ART clients with detectable VL within three months of receipt of results at the health facility. Descriptive statistics and multivariable logistic regression analyses were used to evaluate factors associated with linkage to IAC. RESULTS Of 4,100 HIV-positive persons on ART for at least 6 months, 411 (10%) had detectable VL. The median age was 32 years (interquartile range [IQR] 13-43) and 52% were female. The median duration on ART was 3.2 years (IQR 1.8-4.8). A total of 311 ART clients (81%) were linked to IAC. Receipt of ART at a Health Center level IV was associated with a two-fold higher odds of IAC linkage compared with Health Center level III (adjusted odds ratio [aOR] 1.78; 95% CI 1.00-3.16; p = 0.01). Age, gender, marital status and ART duration were not related to IAC linkage. CONCLUSIONS Linkage to IAC was high among persons with detectable VL in rural Uganda, with greater odds of linkage at a higher-level health facility. Strategies to optimize IAC linkage at lower-level health facilities for persons with suboptimal ART adherence are needed.

Abstract
Aim
To assess inequity in utilization of health care facilities during childbirth and factors associated with home births in Lira district, Northern Uganda.
Subjects and methods
In 2016, we surveyed 930 mothers with children under the age of 2 years in Lira district, Northern Uganda. We used multiple correspondence analysis to construct the wealth index in quintiles, based on household assets. The concentration index is the measure of socioeconomic inequality used in this article, which we calculated using the Stata DASP package. We also conducted multivariable logistic regression to assess factors associated with home births.
Results
A third of mothers (n = 308) gave birth from home [33%, 95% confidence interval (CI) (26%–41%)]. Giving birth at a health facility was pro-rich with a concentration index of 0.10 [95% CI (0.05–0.14)]. Upon decomposing the concentration index, the most important determinant of inequity was the mother's residence. Factors associated with home births in multivariable logistic regression included rural residence [adjusted odds ratio (AOR) 3.1, 95% CI (1.8–5.3)], precipitate labor [AOR 4.18, 95% CI (2.61–6.71)], and labor starting in the evening or at night. Mothers who had previously given birth from home were more likely to give birth at home again [AOR 40.70, 95% CI (18.70–88.61)], whereas mothers who had experienced a complication during a previous birth were less likely to give birth at home [AOR 0.45, 95% CI (0.28–0.95)].
Conclusion
There was inequity in the utilization of health facilities for childbirth. Programs that promote health facility births should prioritize poorer mothers and those in rural areas.

Abstract
Background: Intra-abdominal hypertension (IAH) is sustained increase in intra-abdominal pressure (IAP) ≥12 mmHg in adults and ≥10 mmHg in children. IAH has been noted to be associated with increased morbidity and mortality among critically ill patients. Measurement of IAP is common among at risk patients in the developed world. However, it has not received due attention in the majority of intensive care units (ICUs) in low-income countries, Uganda being one of these. This is evidenced by paucity of data and lack of protocols from the Ugandan Ministry of Health. This multi-center study was thus conducted to assess the prevalence, incidence and mortality associated with IAH among patients admitted to Ugandan ICUs.Methods:A multi-center prospective cohort study was conducted from September 2017 to February 2018 at three ICUs in Uganda. We consecutively enrolled 126 patients into the study. IAP was measured using the Harrahil manometer technique. Categorical variables were analyzed using the Chi square test and continuous variables analyzed using the t-test and Man Whitney test. The prevalence and incidence were determined using proportions and mortality was determined using survival analysis.Results:The median age was 33 years (26-48.5) for the patients without IAH and 42 years (29-55) for those with IAH. The majority of the patients were male and 9.6% of the patients were below 18 years. The prevalence of IAH was 62.7 (CI 54.1-71.3), whereas the 24 hour and 72 hour incidence of IAH was 9.3% (CI 1.3-17.2) and 14.3 % (CI 4.1-24.4), respectively. Mortality was higher in patients with IAH compared to those without (p-value 0.003 and 0.028, mean and maximum IAP, respectively). Conclusion:We found a high prevalence and incidence of IAH among critically ill patients, associated with a high mortality. Routine screening for IAH can preempt management strategies to mitigate this.

[PMID: 32331517 PMCID: PMC7181483 DOI: 10.1186/s12887-020-02094-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 04/20/2020] [Indexed: 02/07/2023] Open
Abstract
Background Mortality among children under 5 years of age admitted to malnutrition units in sub-Saharan Africa remains high. The burden of HIV infection, a major risk factor for mortality among patients with severe acute malnutrition (SAM), has reduced due to concerted prevention and treatment strategies. None the less, anecdotal reports from the malnutrition unit at Uganda’s National Referral Hospital (NRH) indicate that there is high mortality among patients with severe acute malnutrition (SAM) in routine care. Uganda has recently adopted the revised World Health Organization (WHO) treatment guidelines for SAM to improve outcomes. The mortality among children with SAM in routine care has not been recently elucidated. We report the magnitude and factors associated with mortality among children under 5 years of age admitted to the NRH for routine care of SAM. Methods This was a cohort study of all severely malnourished children admitted to the NRH between June and October 2017. The primary outcome was two-week mortality. Mortality was calculated using simple proportions and Cox regression analysis was used to determine factors associated with time to mortality. Data was entered into Epidata and analysed using Stata v14. Results Two-hundred-sixty (98.5%) children: 59.6% male; mean age 14.4 (SD 9.4) months, completed two weeks of follow-up. Of these, 25.2% (95% CI 19.9–30.4%) died. In-hospital mortality was 20.7% (95% CI15.9–25.6%). The prevalence of HIV infection was 12.2%. Factors associated with mortality included: positive HIV status (AHR 2.2, (95% CI; 1.2–4.2), p = 0.014), bacteraemia (AHR 9 (95% CI 3.4–23.0), p < 0.001, and low glomerular filtration rate (eGFR), AHR 3.2; (95% CI 1.7–6.3), p = 0.001). Conclusions A 25% mortality among children with severe malnutrition remains unacceptably high despite significant reduction in HIV prevalence. Children with SAM who are HIV infected, have eGFR below 60 mL/min/1.73m2 or have bacteraemia, are more likely to die. Further studies to explore the relationship between eGFR and mortality among children with SAM are needed. Studies to establish efficacious antibiotics are urgently required to inform treatment guidelines for children with SAM.

Coker E, Katamba A, Kizito S, Eskenazi B, Davis JL. Household air pollution profiles associated with persistent childhood cough in urban Uganda. ENVIRONMENT INTERNATIONAL 2020; 136:105471. [PMID: 32044526 PMCID: PMC8772432 DOI: 10.1016/j.envint.2020.105471] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 01/03/2020] [Accepted: 01/06/2020] [Indexed: 06/02/2023]
Abstract
BACKGROUND Most household air pollution (HAP) interventions in developing countries of sub-Saharan Africa have focused on a single source, such as replacing polluting cooking sources with cleaner burning cooking stoves. Such interventions, however, have resulted in insufficient reductions in HAP levels and respiratory health risks in children. In this study we determined how multiple HAP combustion sources and exposure-mitigation factors in the home environment influence child respiratory health alone and in combination. METHODS We carried out a case-control study to determine associations between multiple indicators of HAP and persistent cough among children (<15 years of age) seeking care at three primary-care clinics in Kampala, Uganda. HAP indicators included self-report of combustion sources inside the home (e.g., stove type, fuel type, and smoking); housing characteristics and cooking practices that mitigate HAP exposure (e.g., use of windows, location of cooking, location of children during cooking) and perceptions of neighborhood air quality. To explore joint associations between indicators of HAP, we applied a Bayesian clustering technique (Bayesian profile regression) to identify HAP indicator profiles most strongly associated with persistent cough in children. RESULTS Most HAP indicators demonstrated significant positive bivariate associations with persistent cough among children, including fuel-type (kerosene), the number of hours burning solid fuels, use of polluting fuels (kerosene or candles) for lighting the home, tobacco smoking indoors, cooking indoors, cooking with children indoors, lack of windows in the cooking area, and not opening windows while cooking. Bayesian cluster analysis revealed 11 clusters of HAP indicator profiles. Compared to a reference cluster that was representative of the underlying study population cough prevalence, three clusters with profiles characterized by highly adverse HAP indicators resulted in ORs of 1.72 (95% credible interval: 1.15, 2.60), 4.74 (2.88, 8.0), and 8.6 (3.9, 23.9). Conversely, at least two clusters of HAP indicator-profiles were protective compared to the reference cluster, despite the fact that these protective HAP indicator profiles used solid fuels for cooking in combination with an unimproved stove (cooking was performed predominantly outdoors in these protective clusters). CONCLUSIONS In addition to cooking fuel and type of cook stove, multiple HAP indicators were strongly associated with persistent cough in children. Bayesian profile regression revealed that the combination of HAP sources and HAP exposure-mitigating factors was driving risk of adverse cough associations in children, rather than any single HAP source at the home.

Abstract
Background and aims In sub-Saharan Africa, infectious diseases are still the leading causes of mortality; however, this may soon be surpassed by non-communicable illnesses, namely hypertension, diabetes and cardiovascular disease. This study determined the prevalence and patterns of metabolic syndrome and cardio-risk factors in men and women in rural Uganda. Methods A household-based, cross-sectional survey was carried out following the WHO STEP-wise approach to surveillance. It included demographic and lifestyle questionnaires, anthropometric measurements and biochemical analyses. Of the 200 randomly recruited participants, 183 successfully completed two steps of the study and 161 provided blood samples. Results Data were collected from 183 adults, aged 18–69 years; 62% were female. Based on the National Cholesterol Education Program-Adult Treatment Panel-III criteria, the prevalence of metabolic syndrome was 19.1% (95% CI 14.0 to 22.5). Elevated fasting plasma glucose was observed in 14.2% (95% CI 9.1 to 19.3) of participants, hypertriglyceridaemia in 16.9% (95% CI 12.1 to 23.1); hypertension in 36.1% (95% CI 29.0 to 43.0) and 52.5% (95% CI 45.2 to 59.6) had low HDL (high-density lipoprotein) cholesterol. Abdominal obesity was found in 24.6% (95% CI 18.8 to 31.4) of participants. Sex disparities were significant for several risk factors. Females had significantly higher prevalence of abdominal obesity (38.6% vs 1.5% in males, p=0.001) and twice the rates of low HDL (65.8% vs 30.4%, p=0.001). Men tended to have higher but not significant rates of hypertension (42.0% vs 32.5%) and smoked significantly more than women (49.3% vs 21.1%, p<0.001). Alcohol consumption was also higher in men (55.1% vs 18.4%, p<0.001) and quantities consumed were approximately three times greater than in females (p<0.001). Conclusion Metabolic syndrome exists at worrying rates in the rural Ugandan population. Sex disparities are evident in risk factor prevalence, reflecting physiological variables and deeply entrenched cultural and lifestyle norms.

Abstract
OBJECTIVE To assess the quality of routine childhood tuberculosis (TB) evaluation in Kampala, Uganda. SETTING AND DESIGN This was a cross-sectional study of children aged <15 years attending six government-run clinics from November 2015 to December 2016. Clinicians completed a standardized patient record form for all child visits. We assessed the following performance indicators of TB evaluation developed based on the Desk Guide of the International Union Against Tuberculosis and Lung Disease, an evidence-based decision aid on childhood TB diagnosis and management for clinicians: proportion screened for TB symptoms or contact history, proportion referred for laboratory evaluation if screen-positive, and proportion treated for TB if test-positive or meeting clinical criteria. RESULTS Of 24 566 consecutive children enrolled, 11 614 (47%) were fully screened for TB symptoms. Of 1747 (15%) children who screened positive, 360 (21%) had sputum examined, including 159 (44%) using smear microscopy, 244 (67%) using Xpert® MTB/RIF, and 52 (14%) using both techniques. Treatment was initiated in 18/20 (80%) children who tested positive. An additional 65 screen-positive children met the clinical criteria for TB; none were initiated on treatment. CONCLUSIONS Large gaps exist along the pathway to diagnosis and treatment of childhood TB. There is an urgent need for enhanced implementation of evidence-based approaches to TB diagnosis to improve outcomes in childhood TB.

Abstract
Introduction Animal bite injuries are a common public health concern in Uganda. We sought to characterize animal bite injuries among patients presenting to Mulago National Referral Hospital in Kampala, Uganda. Methods This was a cross sectional study from 1st September to 30th November 2011. Participants were animal bite injury victims presenting to the accident and emergency (A&E) unit at Mulago hospital and were consecutively enrolled into the study. Socio-demographics, severity and patterns of injury, health seeking and dog handling behaviours were assessed using a standardized questionnaire. Descriptive statistics was used to summarize participant characteristics and the animal bite injuries. Poisson regression model's incident rate ratios (IRR) was used to explore the relationship of the number of days to accessing treatment at Mulago hospital with; a) received prior first aid, b) animal bite injury sustained during day time, c) unknown dog and d) victim resident in Kampala. Data were analyzed using STATA version 12.0 and statistical significance set at P < 0.05. Results Of 25,420 patients that presented to the A&E unit during the study period, 207 (0.8%) had animal bite injuries, mean age 22.7 years (SD 14.3), 64.7% male, and 40.1% were <18 years. Majority 199 (96.1%) were bitten by a lone unrestrained and un-signaled dog that had bitten someone else in 22.2% of cases, and eight victims (0.4%) were attacked in canine gangs of 2-5 dogs. Rabies vaccination was confirmed in only 23 dogs (11.1%) as 109 (52.7%) were unknown to the victims or the communities. One hundred and eighteen victims (57.0%) sustained the dog bites within Kampala district whilst the rest occurred near or far from Kampala district, and the victims especially referred to access anti-rabies vaccine. Of 207, 189 victims (91.3%) presented within 2.6 days (SD ± 4.3). Two hundred victims (96.6%) sustained extremity injuries while the rest had injuries to other body parts. All injuries were minor and managed on out-patient basis with wound dressing, analgesics, prophylactic antibiotics and anti-rabies vaccination. Victims who received prior first aid had a rate of 1.7 times greater for seeking treatment at Mulago hospital (IRR 1.7, 95% CI 1.4-2.1) compared to those that had no prior first aid. Participants who sustained the animal bite injuries during day time had a rate of 1.6 times greater for seeking treatment at Mulago hospital (IRR 1.6, 95% CI 1.3-2.1) compared to those that sustained injuries at other times. Participants bitten by unknown dog and participants residing in Kampala had IRR 0.7, 95% CI 0.5-0.9 and IRR 0.6, 95% CI 0.5-0.8 respectively of accessing treatment at Mulago hospital compared to bitten by known dog and not residing in Kampala. Conclusion Dog bites injuries from unrestrained, un-signaled dogs are the commonest source of animal bite injuries especially among children (<18 years). Vaccination against rabies was only confirmed for a very small number of dogs, as majority were unknown and likely stray dogs. Government and public sensitization is urgently required to limit stray dogs, vaccinate dogs and restrain them to prevent a grave probability of a looming canine rabies epidemic.

Abstract
Background The aim of this study was to determine the prevalence and factors associated with microalbuminuria among newly diagnosed diabetic patients in Mulago National Referral Hospital, Uganda. Methods In this cross-sectional study conducted between June 2014 and January 2015, we collected information on patients' socio-demographics, biophysical profile, blood pressure, biochemical testing and echocardiographic findings using a pre-tested questionnaire. Bivariate and multivariate logistic regression analyses were used to investigate the association of several factors with microalbuminuria. Results Of the 175 patients recruited, males were 90(51.4%) and the mean age was 46±15 years. Majority of patients had type 2 DM 140 (80.0%) and the rest had type 1 DM 35 (20.0%). Mean glycated hemoglobin (HbA1C) was 13.9±5.3%. Mean duration of diabetes was 2 months. Prevalence of microalbuminuria was 47.4 % (95% CI: 40.0%-54.9%) overall. Pregnancy was associated with microalbuminuria (OR7.74[95%CI.1.01–76.47] P=0.050) while mild and moderate physical activity at work were inversely associated with microalbuminuria respectively (OR0.08[95%CI0.01–0.95] P=0.046) and (OR0.07[95%CI0.01–0.77] P=0.030). Conclusion Prevalence of microalbuminuria was high in this group. Physical activity at work may be protective against microalbuminuria and this calls for longitudinal studies. Early detection and management of microalbuminuria in diabetics may slow progression to overt diabetic nephropathy (DN).

Association between CD4 T cell counts and the immune status among adult critically ill HIV-negative patients in intensive care units in Uganda. AAS Open Res 2019; 2:2. [PMID: 31517248 PMCID: PMC6742509 DOI: 10.12688/aasopenres.12925.1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/03/2019] [Indexed: 01/21/2023] Open
Abstract
Background: Cluster of differentiation 4 (CD4) T cells play a central role in regulation of adaptive T cell-mediated immune responses. Low CD4 T cell counts are not routinely reported as a marker of immune deficiency among HIV-negative individuals, as is the norm among their HIV positive counterparts. Despite evidence of mortality rates as high as 40% among Ugandan critically ill HIV-negative patients, the use of CD4 T cell counts as a measure of the immune status has never been explored among this population. This study assessed the immune status of adult critically ill HIV-negative patients admitted to Ugandan intensive care units (ICUs) using CD4 T cell count as a surrogate marker. Methods: A multicentre prospective cohort was conducted between 1st August 2017 and 1st March 2018 at four Ugandan ICUs. A total of 130 critically ill HIV negative patients were consecutively enrolled into the study. Data on sociodemographics, clinical characteristics, critical illness scores, CD4 T cell counts were obtained at baseline and mortality at day 28. Results: The mean age of patients was 45± 18 years (mean±SD) and majority (60.8%) were male. After a 28-day follow up, 71 [54.6%, 95% CI (45.9-63.3)] were found to have CD4 counts less than 500 cells/mm³, which were not found to be significantly associated with mortality at day 28, OR (95%) 1 (0.4-2.4), p = 0.093. CD4 cell count receiver operator characteristic curve (ROC) area was 0.5195, comparable to APACHE II ROC area 0.5426 for predicting 24-hour mortality. Conclusions: CD4 T cell counts were generally low among HIV-negative critically ill patients. Low CD4 T cells did not predict ICU mortality at day 28. CD4 T cell counts were not found to be inferior to APACHE II score in predicting 24 hour ICU mortality.

Abstract
Background: Initiation of breastfeeding later than 1 hour after birth is associated with increased neonatal morbidity and mortality. Objective: To determine the prevalence and factors associated with delayed initiation of breastfeeding. Methods: We conducted a survey in 2016 of 930 children under the age of 2 years in Lira district, northern Uganda. Mothers of the children were interviewed and data was collected on mobile phones using Open Data Kit software (https://opendatakit.org). Multivariable logistic regression was used to determine factors associated with delayed initiation of breastfeeding. Results: Almost half [48.2%, 95% confidence interval (CI) (44.3–52.1)] of the mothers delayed initiation of breastfeeding. Factors significantly associated with delayed initiation of breastfeeding in multivariable analysis included caesarean delivery [Adjusted Odds Ratio (AOR) 11.10 95% CI (3.73–33.04)], discarding initial breast milk [AOR 2.02 95% CI (1.41–2.88)], home delivery [AOR 1.43 95% CI (1.04–1.97)] and mother being responsible for initiating breastfeeding as compared to a health worker or relative [AOR 1.73 95% CI (1.33–2.26)]. Mothers having a secondary education were less likely [AOR 0.54 95% CI (0.30–0.96)] to delay initiation of breastfeeding as compared to those with no education. Conclusion: About half the mothers delayed initiation of breastfeeding until after 1 hour after birth. Programs to promote, protect and support breastfeeding in this post conflict region are urgently needed.

Abstract
Setting: Community health workers (CHWs) increasingly deliver community-based human immunodeficiency virus (HIV) counselling and testing (HCT) services. Less is known about how this strategy performs when integrated with household tuberculosis (TB) contact investigations. Objective: We conducted a prospective mixed-methods study to evaluate the feasibility and quality of CHW-facilitated, home-based HCT among household TB contacts. Design: CHWs visited households of consenting TB patients to screen household contacts for TB and HIV. They performed HIV testing using a serial enzyme-linked immunosorbent assay rapid-antibody testing algorithm. Laboratory technicians at health facilities re-tested the samples and coordinated quarterly HIV panel testing for CHWs. We conducted focus group discussions (FGDs) with CHWs on their experiences in carrying out home-based HCT. Results: Of 114 household contacts who consented to and underwent HIV testing by CHWs, 5 (4%) tested positive, 108 (95%) tested negative, and 1 (1%) had indeterminate results; 110 (96%) samples had adequate volume for re-testing. Overall agreement between CHWs and laboratory technicians was 99.1% (κ = 0.90, 95%CI 0.71-1.00, P < 0.0001). In FGDs, CHWs described context-specific social challenges to performing HCT in a household setting, but said that their confidence grew with experience. Conclusion: Home-based HCT by CHWs was feasible among household TB contacts and produced high-quality results. Strategies to address social challenges are required to optimize yield.

Abstract
BACKGROUND The prevalence of hypertension in patients with diabetes is approximately two-fold higher than in age-matched subjects without the disease and, conversely, individuals with hypertension are at increased risk of developing diabetes compared with normotensive persons. Up to 75% of cases of cardiovascular disease (CVD) in patients with diabetes are attributed to hypertension. Diabetics who have hypertension are more likely to develop complications and die, and appropriate blood pressure control in these individuals reduces the risk. This study sought to determine the prevalence and factors associated with hypertension among newly diagnosed adult diabetic patients in a national referral hospital in Uganda. METHODS In this cross-sectional study, conducted between June 2014 and January 2015, we recruited 201 newly diagnosed adult diabetic patients. Information on patients' socio-demographics was obtained using a pre-tested questionnaire, while biophysical profile, blood pressure measurement, biochemical testing and echocardiographic findings were obtained by the research team for all the participants. Bivariate and multivariate logistic regression analyses were used to investigate the association of several factors with hypertension. RESULTS Of the 201 patients recruited, 102 were male (50.8%) and the mean age was 46 ± 15 years. The majority of patients (159) had type 2 diabetes mellitus (DM) (79.1%) with a mean HbA1c level of 13.9 ± 5.3%. The prevalence of hypertension was 61.9% (95% CI: 54.8-68.6%). Knowledge of hypertension status was at 56 (27.7%) patients, 24 (44.4%) hypertensives were on treatment, and 19 (33.9%) were using ACE inhibitors/angiotensin receptor blockers. The independent factors associated with hypertension were being employed (OR 0.37, 95% CI: 0.16-0.90, p = 0.029) and being overweight or obese (OR 11.6, 95% CI: 4.29-31.2, p < 0.0001). CONCLUSION The prevalence of hypertension was high in this population of newly diagnosed diabetics, few patients had knowledge of their hypertension status and few were on appropriate treatment. Both modifiable and non-modifiable risk factors were associated with hypertension in this group. Therefore routine assessment, treatment and control of hypertension among diabetics is necessary to prevent cardiovascular complications and death. There is also a need to address the modifiable risk factors.

Abstract
An important aspect of the new sustainable development goals (SDGs) is a greater emphasis on reducing the health impacts from ambient air pollution in developing countries. Meanwhile, the burden of human disease attributable to ambient air pollution in sub-Saharan Africa is growing, yet estimates of its impact on the region are possibly underestimated due to a lack of air quality monitoring, a paucity of air pollution epidemiological studies, and important population vulnerabilities in the region. The lack of ambient air pollution epidemiologic data in sub-Saharan Africa is also an important global health disparity. Thousands of air pollution health effects studies have been conducted in Europe and North America, rather than in urban areas that have some of the highest measured air pollution levels in world, including urban areas in sub-Saharan Africa. In this paper, we provide a systematic and narrative review of the literature on ambient air pollution epidemiological studies that have been conducted in the region to date. Our review of the literature focuses on epidemiologic studies that measure air pollutants and relate air pollution measurements with various health outcomes. We highlight the gaps in ambient air pollution epidemiological studies conducted in different sub-regions of sub-Saharan Africa and provide methodological recommendations for future environmental epidemiology studies addressing ambient air pollution in the region.

Abstract
Background Uganda is beset by a shortage of health workers and the few available are mal-distributed. Providing rural exposure through community-based education could positively influence students’ perspectives towards work in rural areas. We aimed to assess the impact of Community-Based Education and Research (COBERS) on health professions students’ attitudes towards working in rural areas. This was a before-and-after study among 525 students of 4 medical universities in Uganda. Data was collected using self-administered paper-based questionnaires. Logistic regression and Poisson regression respectively were used to assess intention and intended number of years of work in rural areas. Results Before COBERS, 228/518 (44.0%) students indicated that they intended to work in rural areas as compared to 245/506 (48.4%) after the COBERS placement. Before the COBERS placement, the factors that were associated with students considering to work in a rural area were: extra allowance (OR = 0.2; 95% CI 0.1–0.6), and availability of social amenities (OR = 0.2; 95% CI 0.1–0.7). After their COBERS placement, the factors were: access to long distance courses (OR = 2.0; 95% CI 1.0–3.7) and being posted to a facility in a rural area (OR = 15.0; 95% CI 6.5–35.5). Before the COBERS placement the factors that influenced how long students thought they would be willing to work in a rural environment were: reliable electricity (IRR = 0.6; 95% CI 0.3–1.0) and Internet (IRR = 1.5; 95% CI 1.0–2.3), high salary (IRR = 0.4; 95% CI 0.3–0.7), and having skills to practice in rural settings (IRR = 2.0; 95% CI 1.3–3.1). Reliable electricity (IRR = 0.5; 95% CI 0.3–0.8) and long distance courses (IRR = 2.1; 95% CI 1.4–3.1) were significant motivators after having undergone the COBERS placement. Conclusions The majority of health professions students do not intend to work in rural areas after they graduate. Improving the welfare of health professionals working in rural areas could attract more health professionals to rural areas thus addressing the maldistribution of health workers in Uganda.
