Public health and research ethics education: the experience of developing a new cadre of bioethicists at a Ugandan institution.

Research ethics education is critical to developing a culture of responsible conduct of research. Many countries in sub-Saharan Africa (SSA) have a high burden of infectious diseases like HIV and malaria; some, like Uganda, have recurring outbreaks. Coupled with the increase in non-communicable diseases, researchers have access to large populations to test new medications and vaccines. The need to develop multi-level capacity in research ethics in Uganda is still huge, being compounded by the high burden of disease and challenging public health issues. Only a few institutions in the SSA offer graduate training in research ethics, implying that the proposed ideal of each high-volume research ethics committee having at least one member with in-depth training in ethics is far from reality. Finding best practices for comparable situations and training requirements is challenging because there is currently no "gold standard" for teaching research ethics and little published information on curriculum and implementation strategies. The purpose of this paper is to describe a model of research ethics (RE) education as a track in an existing 2-year Master of Public Health (MPH) to provide training for developing specific applied learning skills to address contemporary and emerging needs for biomedical and public health research in a highly disease-burdened country. We describe our five-year experience in successful implementation of the MPH-RE program by the Mbarara University Research Ethics Education Program at Mbarara University of Science and Technology in southwestern Uganda. We used curriculum materials, applications to the program, post-training and external evaluations, and annual reports for this work. This model can be adapted and used elsewhere in developing countries with similar contexts. Establishing an interface between public health and research ethics requires integration of the two early in the delivery of the MPH-RE program to prevent a disconnect in knowledge between research methods provided by the MPH component of the MPH-RE program and for research in ethics that MPH-RE students are expected to perform for their dissertation. Promoting bioethics education, which is multi-disciplinary, in institutions where it is still "foreign" is challenging and necessitates supportive leadership at all institutional levels.

Neonatal Paenibacilliosis: Paenibacillus Infection as a Novel Cause of Sepsis in Term Neonates With High Risk of Sequelae in Uganda.

BACKGROUND: Paenibacillus thiaminolyticus may be an underdiagnosed cause of neonatal sepsis. METHODS: We prospectively enrolled a cohort of 800 full-term neonates presenting with a clinical diagnosis of sepsis at 2 Ugandan hospitals. Quantitative polymerase chain reaction specific to P. thiaminolyticus and to the Paenibacillus genus were performed on the blood and cerebrospinal fluid (CSF) of 631 neonates who had both specimen types available. Neonates with Paenibacillus genus or species detected in either specimen type were considered to potentially have paenibacilliosis, (37/631, 6%). We described antenatal, perinatal, and neonatal characteristics, presenting signs, and 12-month developmental outcomes for neonates with paenibacilliosis versus clinical sepsis due to other causes. RESULTS: Median age at presentation was 3 days (interquartile range 1, 7). Fever (92%), irritability (84%), and clinical signs of seizures (51%) were common. Eleven (30%) had an adverse outcome: 5 (14%) neonates died during the first year of life; 5 of 32 (16%) survivors developed postinfectious hydrocephalus (PIH) and 1 (3%) additional survivor had neurodevelopmental impairment without hydrocephalus. CONCLUSIONS: Paenibacillus species was identified in 6% of neonates with signs of sepsis who presented to 2 Ugandan referral hospitals; 70% were P. thiaminolyticus. Improved diagnostics for neonatal sepsis are urgently needed. Optimal antibiotic treatment for this infection is unknown but ampicillin and vancomycin will be ineffective in many cases. These results highlight the need to consider local pathogen prevalence and the possibility of unusual pathogens when determining antibiotic choice for neonatal sepsis.

Understanding the barriers and enablers for postgraduate medical trainees becoming simulation educators: a qualitative study.

INTRODUCTION : There is increasing evidence that Simulation-based learning (SBL) is an effective teaching method for healthcare professionals. However, SBL requires a large number of faculty to facilitate small group sessions. Like many other African contexts, Mbarara University of Science and Technology (MUST) in Uganda has large numbers of medical students, but limited resources, including limited simulation trained teaching faculty. Postgraduate medical trainees (PGs) are often involved in clinical teaching of undergraduates. To establish sustainable SBL in undergraduate medical education (UME), the support of PGs is crucial, making it critical to understand the enablers and barriers of PGs to become simulation educators. METHODS: We used purposive sampling and conducted in-depth interviews (IDIs) with the PGs, key informant interviews (KIIs) with university staff, and focus group discussions (FGDs) with the PGs in groups of 5-10 participants. Data collection tools were developed using the Consolidated framework for implementation research (CFIR) tool. Data were analyzed using the rigorous and accelerated data reduction (RADaR) technique. RESULTS: We conducted seven IDIs, seven KIIs and four focus group discussions. The barriers identified included: competing time demands, negative attitude towards transferability of simulation learning, inadequacy of medical simulation equipment, and that medical simulation facilitation is not integrated in the PGs curriculum. The enablers included: perceived benefits of medical simulation to medical students plus PGs and in-practice health personnel, favorable departmental attitude, enthusiasm of PGs to be simulation educators, and improved awareness of the duties of a simulation educator. Participants recommended sensitization of key stakeholders to simulation, training and motivation of PG educators, and evaluation of the impact of a medical simulation program that involves PGs as educators. CONCLUSION: In the context of a low resource setting with large undergraduate classes and limited faculty members, SBL can assist in clinical skill acquisition. Training of PGs as simulation educators should address perceived barriers and integration of SBL into UME. Involvement of departmental leadership and obtaining their approval is critical in the involvement of PGs as simulation educators.

Problem Gambling Among Adolescents in Uganda: A Cross-sectional Survey Study.

In recent years, gambling has evolved and grown substantially with new gambling activities and facilities being introduced, making gambling products and opportunities more available than ever before in Uganda. While the growth of gambling industry is considered to have a beneficial impact on the economy, it is increasingly becoming a social and public health issue especially among a minority of young people who experience problem gambling, which can damage personal, family, vocational, and academic pursuits. The present study estimated the prevalence of problem gambling and identified the socio-demographic, school, environmental and health risks of problem gambling among secondary school students in Mbarara Municipality, Uganda. A cross-sectional study was conducted among secondary school students in Mbarara Municipality. A total of 921 students from 12 schools were recruited using cluster sampling. An ordinal logistic regression model was used to explore the relationship between problem gambling and the socio-demographic, academic, environmental and health variables. Of 905 participants, 362 reported having ever gambled (40%), and 160 were classified as problem gamblers (17.7%; 44.2% among those who had ever gambled). Problem gambling was significantly associated with being male, being non-religious, other religion (African traditional religion), having employment (outside of school), distance to nearest gambling venue, parental gambling, peer gambling, substance use, risky sexual behavior, and psychological distress. The present study found a very high prevalence of problem gambling among Ugandan secondary school students. Therefore, there is need to institute public health measures towards raising awareness, prevention and treatment of problem gambling among Ugandan adolescents.

Neighborhood greenness and burden of non-communicable diseases in Sub-Saharan Africa: A multi-country cross-sectional study.

Population growth, demographic transitions and urbanization in sub-Saharan Africa (SSA) will increase non-communicable disease (NCD) burden. We studied the association between neighborhood greenness and NCDs in a multi-country cross-sectional study. Among 1178 participants, in adjusted models, a 0.11 unit NDVI increase was associated with lower BMI (ß: -1.01, 95% CI: -1.35, -0.67), and lower odds of overweight/obesity (aOR: 0.73, 95% CI: 0.62, 0.85), diabetes (aOR: 0.77, 95% CI: 0.62, 0.96), and having ≥3 allostatic load components compared to none (aOR: 0.66, 95% CI: 0.52, 0.85). Except for diabetes, these remained statistically significant after Bonferroni correction. We observed no association between NDVI and hypertension or cholesterol. Our findings are consistent with health benefits of neighborhood greenness reported in other countries, suggesting greening strategies could be considered as part of broader public health interventions for NCDs.

Alcohol consumption and sports-betting among young male motorcycle taxi boda boda riders in urban southwestern Uganda.

BACKGROUND: The popularity of sports-betting is growing globally and may be associated with alcohol consumption among young adults. In this study, we examine the relationship between alcohol consumption plus other substances with sports-betting in a group of young adult males in Uganda. METHODS: We conducted a cross-sectional study and interviewed male motorcycle taxi boda boda riders in the southwestern Uganda town of Mbarara. We asked questions about alcohol consumption, smoking plus history and frequency of sports-betting. RESULTS: We enrolled 401 riders. The median age was 29.0 years, interquartile range 25-32 years. Seventy four (18.5%) had engaged in sports-betting in the past 30 days. Among those that reported sports-betting, 16(21.6%) engaged daily or almost daily. Alcohol use was significantly associated with sports-betting with an adjusted risk ratio (aRR) of 2.08(95% CI 1.36, 3.18) among moderate drinkers but not among heavy drinkers in comparison to low or non-drinkers. Cigarette smoking was significantly associated with sports-betting with an aRR 1.85(95% CI 1.13, 3.01). CONCLUSION: Sports-betting is common among these young male motorcycle riders, and is associated with both alcohol consumption and cigarette smoking. Interventions to regulate sports-betting may be co-packaged with those to reduce alcohol consumption and cigarette smoking among young adult males.

Associations between red blood cell variants and malaria among children and adults from three areas of Uganda: a prospective cohort study.

BACKGROUND: Multiple red blood cell (RBC) variants appear to offer protection against the most severe forms of Plasmodium falciparum malaria. Associations between these variants and uncomplicated malaria are less clear. METHODS: Data from a longitudinal cohort study conducted in 3 sub-counties in Uganda was used to quantify associations between three red blood cell variants Hb [AA, AS, S (rs334)], alpha thalassaemia 3.7 kb deletion, and glucose-6-phosphate dehydrogenase deficiency A-(G6PD 202A genotype) and malaria incidence, parasite prevalence, parasite density (a measure of anti-parasite immunity) and body temperature adjusted for parasite density (a measure of anti-disease immunity). All analyses were adjusted for age, average household entomological inoculation rate, and study site. Results for all variants were compared to those for wild type genotypes. RESULTS: In children, HbAS was associated, compared to wild type, with a lower incidence of malaria (IRR = 0.78, 95% CI 0.66-0.92, p = 0.003), lower parasite density upon infection (PR = 0.66, 95% CI 0.51-0.85, p = 0.001), and lower body temperature for any given parasite density (- 0.13 â„ƒ, 95% CI - 0.21, - 0.05, p = 0.002). In children, HbSS was associated with a lower incidence of malaria (IRR = 0.17, 95% CI 0.04-0.71, p = 0.02) and lower parasite density upon infection (PR = 0.31, 95% CI 0.18-0.54, p < 0.001). α-/αα thalassaemia, was associated with higher parasite prevalence in both children and adults (RR = 1.23, 95% CI 1.06-1.43, p = 0.008 and RR = 1.52, 95% CI 1.04-2.23, p = 0.03, respectively). G6PD deficiency was associated with lower body temperature for any given parasite density only among male hemizygote children (- 0.19 â„ƒ, 95% CI - 0.31, - 0.06, p = 0.003). CONCLUSION: RBC variants were associated with non-severe malaria outcomes. Elucidation of the mechanisms by which they confer protection will improve understanding of genetic protection against malaria.

Effectiveness of a mobile antiretroviral pharmacy and HIV care intervention on the continuum of HIV care in rural Uganda.

Adherence to antiretroviral therapy (ART) is critical in order to achieve viral suppression. We designed an intervention, Mobile Antiretroviral Therapy and HIV care (MAP-HC) in rural southwestern Uganda aimed to reduce travel distance and hypothesized that MAP-HC would improve ART adherence and rates of viral load suppression. The study was conducted at two district hospitals, among patients who lived >5 km from the hospital. For each hospital, we identified 4 health centers in the catchment area to serve as site for the mobile pharmacy. Each site was visited once a month to provide ART refills and adherence counseling. We measured patient waiting time, adherence and viral load suppression before and after the intervention. The proportion of patients who missed an ART dose in the last 30 days dropped from 20% to 8.5% at 12 months post-intervention (p = 0.009) and those with detectable viral load dropped from 19.9% to 7.4% (p = 0.001), however, mean waiting time increased from 4.48 to 4.76 h (p = 0.13). Mobile pharmacy intervention in rural Uganda is feasible and resulted in improvement in adherence and viral load suppression. Although it did not reduce patient waiting time at the clinic, we recommend scale-up in rural areas where patients face transportation challenges.

A Randomized Controlled Trial of Enhanced Recovery After Surgery Versus Standard of Care Recovery for Emergency Cesarean Deliveries at Mbarara Hospital, Uganda.

BACKGROUND: Enhanced recovery after surgery (ERAS) expedites return to patient baseline and functional status by reducing surgical trauma, stress, and organ dysfunction. Despite the potential benefits of enhanced recovery protocols, limited research has been done in low-resource settings, where 95% of cesarean deliveries are emergent and could possibly benefit from the application of ERAS protocols. METHODS: In a prospective, randomized, single-blind, controlled trial, mothers delivering by emergency cesarean delivery were randomly assigned to either an ERAS or a standard of care (SOC) recovery arm. Patients in the ERAS arm were treated with a modified ERAS protocol that included modified counseling and education, prophylactic antibiotics, antiemetics, normothermia, restrictive fluid administration, and multimodal analgesia. They also received early initiation of mobilization, feeding, and urethral catheter removal. The primary end point was length of hospital stay. The secondary end points were complications and readmission rates. Mean length of stay in the intervention and control arms were compared using t tests. Statistical analyses were performed using STATA version 13 (College Station, TX). RESULTS: A total of 160 patients were enrolled in the study, with 80 randomized to each arm. There was a statistically significant shorter length of stay for the ERAS arm compared to SOC, with a difference of -18.5 hours (P < .001, 95% confidence interval [CI], -23.67, -13.34). The incidence of complications of severe pain and headache was lower in the ERAS arm compared to SOC (P = .001 for both complications). However, pruritus was more common in the ERAS arm compared to SOC (P = .023). CONCLUSIONS: Use of an ERAS protocol for women undergoing emergency cesarean delivery in a low-income setting is feasible and reduces length of hospital stay without generally increasing the complication rate.

Geographic location of health facility and immunization program performance in Hoima district, western Uganda: a health facility level assessment.

BACKGROUND: Globally, immunization coverage for childhood vaccines is below the immunization target of achieving at least 90% coverage with the pentavalent vaccine. In Uganda, a recent survey shows 80% of districts had poor immunization program performance. However, there is significant variation in performance within and between districts. We hypothesized that geographic location of a health facility may influence performance of its immunization programs. Therefore, the purpose of this study was to examine whether geographical location of a health facility within a district is associated with performance of the immunization program in Hoima district, western Uganda. METHODS: We conducted a cross sectional study using a mixed methods approach. The main study unit was a health center and we also interviewed health workers in-charge of the facilities and reviewed their health facility records. We reviewed the Uganda Health Management Information System (HMIS) 105 reports of six months to obtain data on immunization program performance. Performance was categorized using World Health Organization's Reach Every District (RED) criteria and classified as poor if a facility fell in category 3 or 4 and good if 1 or 2. We also conducted key informant interviews with immunization focal persons in the district. We examined the association between dependent and independent variables using Fisher's exact test. RESULTS: We collected data at 49 health facilities. Most of these facilities (55.1%) had poor immunization program performance. Proximal location to the central district headquarters was significantly associated with poor immunization program performance (p < 0.05). Attitudes of health workers in the more urban areas, differences in strategies for outreach site selection and community mobilization in the rural and urban areas were suggested as possible explanations. CONCLUSIONS: Proximal location to the urban setting near district headquarters was strongly associated with poor immunization program performance. To be able to reach larger numbers of children for vaccination, interventions to improve performance should target health facilities in urban settings.

Treatment success and mortality among adults with tuberculosis in rural eastern Uganda: a retrospective cohort study.

BACKGROUND: Successful treatment of tuberculosis leads to clinical and public health benefits such as reduction in transmission, complications, and mortality among patients. However, data are limited on treatment outcomes and the associated factors among persons with bacteriologically confirmed pulmonary (BC-PTB) in rural areas of high dual tuberculosis and Human Immunodeficiency Virus (HIV) burden countries such as Uganda. We investigated factors associated with successful treatment of tuberculosis and mortality among adult persons with BC-PTB in rural eastern Uganda. METHODS: We constructed a retrospective cohort of persons with BC-PTB from a routine tuberculosis clinic database in eastern Uganda. We performed bivariate and multivariate analysis. Using a 5% level of significance, we ran a modified Poisson regression analysis to determine factors independently associated with treatment success and mortality rates. RESULTS: We retrieved 1123 records for persons with BC-PTB and the treatment outcomes were distributed as follows: 477(42.5%) cured, 323 (28.0%) treatment completed, 17(1.5%) treatment failed, 81(7.2%) died, 89(7.9%) lost to follow-up, and 136(12.1%) not evaluated. Overall, 800 (81.1%) of the 987 persons with BC-PTB that had treatment outcome, were successfully treated. Successful treatment of tuberculosis was less likely to occur among those with HIV infection (Adjusted risk ratio (aRR), 0.88; 95% Confidence Interval (CI), 0.82-0.95), older than 50 years (aRR, 0.89; 95% CI, 0.81-0.97), or male sex (aRR, 0.92; 95% CI, 0.87-0.98). Mortality was associated with HIV infection (aRR, 4.48; 95% CI, 2.95-6.79), older than 50 years (aRR, 2.93; 95% CI, 1.74-4.92), year of enrollment into treatment after 2015 (aRR, 0.80; 95% CI, 0.66-0.97), and Community-Based Directly Observed Therapy Short Course (aRR, 0.26; 95% CI, 0.13-0.50). CONCLUSIONS: Treatment success rate among adult persons with BC-PTB in rural eastern Uganda is suboptimal and mortality rate is high. HIV infection and older age reduce chances of treatment success, and increase mortality rate. Older and HIV infected persons with BC-PTB will require special consideration to optimize treatment success rate and reduce mortality rate.

First-step validation of a text message-based application for newborn clinical management among pediatricians.

BACKGROUND: Neonatal mortality is high in developing countries. Lack of adequate training and insufficient management skills for sick newborn care contribute to these deaths. We developed a phone application dubbed Protecting Infants Remotely by Short Message Service (PRISMS). The PRISMS application uses routine clinical assessments with algorithms to provide newborn clinical management suggestions. We measured the feasibility, acceptability and efficacy of PRISMS by comparing its clinical case management suggestions with those of experienced pediatricians as the gold standard. METHODS: Twelve different newborn case scenarios developed by pediatrics residents, based on real cases they had seen, were managed by pediatricians and PRISMS®. Each pediatrician was randomly assigned six of twelve cases. Pediatricians developed clinical case management plans for all assigned cases and then obtained PRISMS suggested clinical case managements. We calculated percent agreement and kappa (k) statistics to test the null hypothesis that pediatrician and PRISMS management plans were independent. RESULTS: We found high level of agreement between pediatricians and PRISMS for components of newborn care including: 10% dextrose (Agreement = 73.8%), normal saline (Agreement = 73.8%), anticonvulsants (Agreement = 100%), blood transfusion (Agreement =81%), phototherapy (Agreement = 90.5%), and supplemental oxygen (agreement = 69.1%). However, we found poor agreement with potential investigations such as complete blood count, blood culture and lumbar puncture. PRISMS had a user satisfaction score of 3.8 out of 5 (range 1 = strongly disagree, 5 = strongly agree) and an average PRISMS user experience score of 4.1 out of 5 (range 1 = very bad, 5 = very good). CONCLUSION: Management plans for newborn care from PRISMS showed good agreement with management plans from experienced Pediatricians. We acknowledge that the level of agreement was low in some aspects of newborn care.

Stakeholder perceptions about the establishment of medical simulation-based learning at a university in a low resource setting: a qualitative study in Uganda.

BACKGROUND: Simulation based learning (SBL) is a technique where teachers recreate "real life" clinical experiences for health care teams for purposes of gaining clinical skills in a safe environment. There is evidence that SBL is superior to the traditional clinical teaching methods for acquisition of clinical skills. Although it is well established in resource rich settings, there is limited experience in resource limited settings and there is uncertainty regarding how SBL will be perceived among the stakeholders in medical education. As part of the steps leading to implementation of a SBL program at a university in Uganda, we sought to describe the perceptions of various stakeholders regarding the introduction of SBL methodology into learning at a medical school in Uganda. METHODS: We conducted a formative qualitative assessment using key informant interviews (KIIs) among faculty members and university administrators and focus group discussions (FGDs) among medical and nursing students at Mbarara University of Science and Technology. Data were collected till saturation point and were transcribed and analyzed manually using open and axial coding approaches to develop themes. RESULTS: We conducted seven KIIs and three FGDs. Overall, findings were categorized into five broad themes: 1. Motivation to adopt simulation-based learning 2. Prior experience and understanding of simulation-based education 3. Outcomes arising from introduction of medical simulation 4. Drawbacks to establishment of medical simulation; and 5. Potential remedies to the drawbacks. Overall, our data show there was significant buy-in from the institution for SBL, stakeholders were optimistic about the prospects of having a new method of teaching, which they perceived as modern to complement the traditional methods. There was significant knowledge but very limited prior experience of medical simulation. Also, there was some concern regarding how students and faculty would embrace training on lifeless objects, the human resources needed and sustainability of simulation-based learning in the absence of external funding. CONCLUSION: Stakeholders perceive SBL positively and are likely to embrace the learning methods. Concerns about human resource needs and sustainability need to be addressed to ensure acceptability.

Retention of HIV exposed infants in care at Arua regional referral hospital, Uganda: a retrospective cohort study.

BACKGROUND: Retention of HIV Exposed Infants (HEIs) in care ensures adequate care. Data on retention of HEIs at large referral hospitals in Uganda is limited. We investigated the retention level of HEIs and associated factors. METHODS: We conducted a retrospective cohort study on 352 HEIs in care (January 2014 and April 2015) at Arua Regional Referral Hospital, North-western Uganda. Electronic medical data were retrieved and analyzed with Stata. Chi-square, Fisher's exact, and Students t-tests were used for bivariate analysis. Logistic regression was performed to determine factors independently associated with retention. RESULTS: 236 (67.0%) HEIs were delivered in a health facility and 306 (86.9%) received Nevirapine prophylaxis from birth until 6-weeks. Of mothers, 270 (76.7%) were 25-46 years, 202 (57.4%) attended antenatal care (ANC) at recent pregnancy, and 328 (93.2%) were on life-long anti-retroviral therapy. At 18-months, 277 (78.7%) HEIs were retained in care. Maternal age (25-46 years) (Adjusted Odds Ratio (AOR), 2.32; 95% CI, 1.32-4.06), ANC attendance during recent pregnancy (AOR, 2.01; 95% CI, 1.19-4.3.41) and Nevirapine prophylaxis initiation from birth until 6-weeks (AOR, 3.07; 95% CI, 1.50-6.26) were associated with retention. CONCLUSION: Retention was suboptimal. Older maternal age, ANC visits at last pregnancy, and timely NVP initiation increased retention.

Explaining the successes and failures of tuberculosis treatment programs; a tale of two regions in rural eastern Uganda.

BACKGROUND: Optimally performing tuberculosis (TB) programs are characterized by treatment success rate (TSR) of at least 90%. In rural eastern Uganda, and elsewhere in sub Saharan Africa, TSR varies considerably across district TB programs and the reasons for the differences are unclear. This study explored factors associated with the low and high TSR across four districts in rural eastern Uganda. METHODS: We interviewed District TB and Leprosy Supervisors, Laboratory focal persons, and health facility TB focal persons from four districts in eastern Uganda as key informants. Interviews were audio recorded, transcribed verbatim, and imported into ATLAs.ti where thematic content analysis was performed and results were summarized into themes. RESULTS: The emerging themes were categorized as either facilitators of or barriers to treatment success. The emerging facilitators prevailing in the districts with high rates of treatment success were using data to make decisions and design interventions, continuous quality improvement, capacity building, and prioritization of better management of people with TB. The barriers common in districts with low rates of treatment success included lack of motivated and dedicated TB focal persons, scarce or no funding for implementing TB activities, and a poor implementation of community-based directly observed therapy short course. CONCLUSION: This study shows that several factors are associated with the differing rates of treatment success in rural eastern Uganda. These factors should be the focus for TB control programs in Uganda and similar settings in order to improve rates of treatment success.

Consumption of processed food dietary patterns in four African populations.

OBJECTIVE: To identify predominant dietary patterns in four African populations and examine their association with obesity. DESIGN: Cross-sectional study.Setting/SubjectsWe used data from the Africa/Harvard School of Public Health Partnership for Cohort Research and Training (PaCT) pilot study established to investigate the feasibility of a multi-country longitudinal study of non-communicable chronic disease in sub-Saharan Africa. We applied principal component analysis to dietary intake data collected from an FFQ developed for PaCT to ascertain dietary patterns in Tanzania, South Africa, and peri-urban and rural Uganda. The sample consisted of 444 women and 294 men. RESULTS: We identified two dietary patterns: the Mixed Diet pattern characterized by high intakes of unprocessed foods such as vegetables and fresh fish, but also cold cuts and refined grains; and the Processed Diet pattern characterized by high intakes of salad dressing, cold cuts and sweets. Women in the highest tertile of the Processed Diet pattern score were 3·00 times more likely to be overweight (95 % CI 1·66, 5·45; prevalence=74 %) and 4·24 times more likely to be obese (95 % CI 2·23, 8·05; prevalence=44 %) than women in this pattern's lowest tertile (both P<0·0001; prevalence=47 and 14 %, respectively). We found similarly strong associations in men. There was no association between the Mixed Diet pattern and overweight or obesity. CONCLUSIONS: We identified two major dietary patterns in several African populations, a Mixed Diet pattern and a Processed Diet pattern. The Processed Diet pattern was associated with obesity.

Prevalence and risk factor for injury in sub-Saharan Africa: a multicountry study.

INTRODUCTION: Injury-related morbidity is a neglected health concern in many low-income and middle-income countries. Most injury data in Africa have been collected from hospital-based studies, and few studies have occurred across multiple countries. Using data from a novel cohort, we examined the prevalence and incidence of serious injuries and associated risk factors across five sites in sub-Saharan Africa (SSA). METHODS: A common baseline and follow-up survey was administered to participants. The study population included 1316 persons at baseline and 904 persons at follow-up. Frequencies were calculated, and logistic regression models were used to assess risk factors for injury. RESULTS: A total of 233 (17.7%) persons reported a serious injury at baseline and 60 (6.6%) reported a serious injury 6 months later at follow-up. Sixty-nine per cent of participants responded to the follow-up questionnaire. At baseline and follow-up, the most common cause of serious injury at urban sites was transport related, followed by poison/overdose. In rural Uganda, sharp instruments injuries were most common, followed by transport-related injuries. Living at an urban site was associated with an increased odds for serious injury compared with those at the rural site (OR: 1.83, 95% CI 1.15 to 2.90). Participants who consumed above a moderate amount of alcohol were at a higher risk of serious injury compared with those who did not consume alcohol (OR: 1.86, 95% CI 1.02 to 3.41). High level of education was an important risk factor for injury. CONCLUSION: At baseline and follow-up, common causes of serious injury were transport related, sharp instrument and poison/overdose. Alcohol consumption, urban location and education are important risk factors for injury. It is feasible to collect longitudinal injury data using a standardised questionnaire across multiples sites in SSA. Longitudinal data collection should be leveraged to obtain robust data on risk factors for injury in SSA.

Assessing short evolution brucellosis in a highly brucella endemic cattle keeping population of Western Uganda: a complementary use of Rose Bengal test and IgM rapid diagnostic test.

BACKGROUND: Brucellosis is a worldwide and zoonotic disease often sadly misdiagnosed in endemic areas. Challenges of availability and accessibility of diagnostic tools are common in resource constrained populations where the most vulnerable are found, surveillance and diagnosis are limited too. METHODS: A cross-sectional study using a simple two stage cluster sampling method was conducted to measure short evolution brucellosis burden among cattle keeping households that are one of the highest risk populations to be exposed to Brucella infection. A total of 216 households were randomly selected from 18 rural villages from the Western Region of Uganda. Household blood samples were tested for Brucella antibodies using the highly sensitive Rose Bengal test (RBT) and IgM ELISA Lateral Flow Assay (LFA). RESULTS: Among the total tested population, 58.8% did not react with any of the tests, 13.4% reacted with both tests. Among those that reacted with both (N = 29), 62.1% had weak (+ 1) LFA staining, 34.5% had moderate (2+) LFA staining. Altogether, both weak and moderate staining (96.5%) are consistent with sub-acute disease, while only one (3.4%) had strong (3+) LFA staining consistent with acute infection. 19.4% of the samples tested positive only with RBT, consistent with chronic infection, eighteen samples (8.3%) reacted exclusively with IgM LFA. CONCLUSION: We identified a high prevalence of short evolution brucellosis in the cattle keeping household members. Prevalence of chronic infection diagnosed with RBT only was higher than the prevalence of short evolution brucellosis. IgM LFA results depict possible cases of cross reaction with Salmonella spp., Plasmodium etc. Ultimately, we identified a consistent prevalence of short evolution brucellosis in the cattle keeping household members. Indeed, the use of a combined diagnostic with LFA and RBT is easy and amenable for an active disease surveillance and accurate diagnosis in rural settings.

The burden of chronic rhinosinusitis and its effect on quality of life among patients re-attending an otolaryngology clinic in south western Uganda.

BACKGROUND: Worldwide, the burden of chronic rhinosinusitis (CRS) is variable, but not known in Uganda. CRS has significant negative impact on quality of life (QOL) and as such QOL scores should guide adjustments in treatment strategies. However, most of these studies have been done in the west. Our hypothesis was that QOL scores of the majority of CRS patients in low- to- middle income countries are poorer than those among patients without CRS. The aim of this study was to determine the burden of CRS among patients re-attending the Otolaryngology clinic and whether CRS is related to poor QOL. METHODS: A cross sectional study was conducted at Mbarara Regional Referral Hospital Otolaryngology clinic. One hundred and twenty-six adult re-attendees were consecutively recruited. Data was collected using a structured questionnaire and the Sinonasal Outcome Test 22 (SNOT 22) questionnaire measured QOL. RESULTS: The proportion of re-attendees with CRS was 39.0% (95% CI 30-48%). Majority of CRS patients had poor quality of life scores compared to non-CRS (88% versus 20% p < 01). The poor quality of life scores on the SNOT 22 were almost solely as a result of the functional, physical and psychological aspects unique to CRS. CONCLUSIONS: CRS is highly prevalent among re-attendees of an Otolaryngology clinic at a hospital in resource limited settings and has a significant negative impact on the QOL of these patients.

Healthcare providers' understanding of HIV serodiscordance in South Africa and Uganda: implications for HIV prevention in sub-Saharan Africa.

HIV transmission within stable heterosexual HIV serodiscordant couples accounts for almost half the new incident infections in South Africa and Uganda. Advances in HIV prevention provide opportunities to reduce transmission risk within serodiscordant partnerships (e.g., antiretroviral treatment (ART), pre-exposure prophylaxis (PrEP), medical male circumcision, and couples-based HIV counselling and testing). These interventions require a clinical encounter with a provider who recognises prevention opportunities within these partnerships. We explored healthcare provider understanding of HIV serodiscordance in a reproductive counselling study with providers in eThekwini district, South Africa, and Mbarara district, Uganda. In eThekwini, in-depth interviews (29) and focus group discussions (2) were conducted with 42 providers (counsellors, nurses and doctors) from public sector clinics. In Mbarara, in-depth interviews were conducted with 38 providers (medical officers, clinical officers, nurses, peer counsellors and village health workers). Thematic analysis was conducted using NVivo software. In eThekwini, many providers assumed HIV seroconcordance among client partners and had difficulty articulating how serodiscordance occurs. Mbarara providers had a better understanding of HIV serodiscordance. In the two countries, providers who understood HIV serodiscordance were better able to describe useful HIV-prevention strategies. Healthcare providers require training and support to better understand the prevalence and mechanisms of HIV serodiscordance to implement HIV-prevention strategies for HIV serodiscordant couples.
