Item Abundance of megalin and Dab2 is reduced in syncytiotrophoblast during placental malaria, which may contribute to low birth weight(Scientific reports, 2016) Lybbert, Jared; Gullingsrud, Justin; Chesnokov, Olga; Turyakira, Eleanor; Dhorda, Mehul; Guerin, Philippe J.; Piola, Patrice; Muehlenbachs, Atis; Oleinikov, Andrew V.Placental malaria caused by Plasmodium falciparum contributes to ~200,000 child deaths annually, mainly due to low birth weight (LBW). Parasitized erythrocyte sequestration and consequent inflammation in the placenta are common attributes of placental malaria. The precise molecular details of placental changes leading to LBW are still poorly understood. We hypothesized that placental malaria may disturb maternofetal exchange of vitamins, lipids, and hormones mediated by the multiligand (n ~ 50) scavenging/signaling receptor megalin, which is abundantly expressed in placenta but was not previously analyzed in pregnancy outcomes. We studied abundance of megalin and its intracellular adaptor protein Dab2 by immunofluorescence microscopy in placental biopsies from Ugandan women with (n = 8) and without (n = 20) active placental malaria. We found that: (a) abundances of both megalin (p = 0.01) and Dab2 (p = 0.006) were significantly reduced in brush border of syncytiotrophoblast of infected placentas; (b) amounts of megalin and Dab2 were strongly correlated (Spearman’s r = 0.53, p = 0.003); (c) abundances of megalin and Dab2 (p = 0.046) were reduced in infected placentas from women with LBW deliveries. This study provides first evidence that placental malaria infection is associated with reduced abundance of megalin transport/signaling system and indicate that these changes may contribute to the pathology of LBW.Item Artemether-lumefantrine to treat malaria in pregnancy is associated with reduced placental haemozoin deposition compared to quinine in a randomized controlled trial(Malaria journal, 2012) Muehlenbachs, Atis; Nabasumba, Carolyn; McGready, Rose; Turyakira, Eleanor; Tumwebaze, Benon; Dhorda, Mehul; Nyehangane, Dan; Nalusaji, Aisha; Nosten, François; Guerin, Philippe J.; Piola, PatriceData on efficacy of artemisinin-based combination therapy (ACT) to treat Plasmodium falciparum during pregnancy in sub-Saharan Africa is scarce. A recent open label, randomized controlled trial in Mbarara, Uganda demonstrated that artemether-lumefantrine (AL) is not inferior to quinine to treat uncomplicated malaria in pregnancy. Haemozoin can persist in the placenta following clearance of parasites, however there is no data whether ACT can influence the amount of haemozoin or the dynamics of haemozoin clearance. Methods: Women attending antenatal clinics with weekly screening and positive blood smears by microscopy were eligible to participate in the trial and were followed to delivery. Placental haemozoin deposition and inflammation were assessed by histology. To determine whether AL was associated with increased haemozoin clearance, population haemozoin clearance curves were calculated based on the longitudinal data. Results: Of 152 women enrolled in each arm, there were 97 and 98 placental biopsies obtained in the AL and quinine arms, respectively. AL was associated with decreased rates of moderate to high grade haemozoin deposition (13.3% versus 25.8%), which remained significant after correcting for gravidity, time of infection, re-infection, and parasitaemia. The amount of haemozoin proportionately decreased with the duration of time between treatment and delivery and this decline was greater in the AL arm. Haemozoin was not detected in one third of biopsies and the prevalence of inflammation was low, reflecting the efficacy of antenatal care with early detection and prompt treatment of malaria. Conclusions: Placental haemozoin deposition was decreased in the AL arm demonstrating a relationship between pharmacological properties of drug to treat antenatal malaria and placental pathology at delivery. Histology may be considered an informative outcome for clinical trials to evaluate malaria control in pregnancy.

This practice indicates there may be latent demand for a pericoital contraceptive pill taken only when a woman has sexual intercourse, and labeled and marketed for use as a regular contraceptive method. METHODS: To understand the appeal and potential market for a pericoital contraceptive pill, 39 focus groups and 23 in-depth interviews were conducted with women and men in Lucknow, Uttar Pradesh, India, and Kampala, Uganda. A total of 281 individuals participated in this qualitative study. RESULTS: In general, women embraced the idea of a female-controlled method that would be easier than taking a daily oral contraceptive pill and that could be taken either before or after sexual intercourse; in Uganda, especially, women approved of the fact that the method could be taken without a partner's knowledge. Although we do not yet know the extent of side effects for this method, women expressed some concerns about the level and nature of potential side effects. CONCLUSIONS: The results suggest that a pericoital contraceptive pill would be well-received by consumers in both country settings. If its efficacy and side effects are acceptable, a pericoital contraceptive pill could fill a gap for female-controlled, discreet, coitus-related contraception, particularly among women who do not have sex very frequently.Item Context matters in understanding the vulnerability of women: perspectives from southwestern Uganda(Archives of Public Health, 2021) Murembe, Neema; Kyomuhangi, Teddy; Manalili, Kimberly; Beinempaka, Florence; Nakazibwe, Primrose; Kyokushaba, Clare; Tibanyendera, Basil; Brenner, Jennifer L.; Turyakira, EleanorVulnerability at the individual, family, community or organization level affects access and utilization of health services, and is a key consideration for health equity. Several frameworks have been used to explore the concept of vulnerability and identified demographics including ethnicity, economic class, level of education, and geographical location. While the magnitude of vulnerable populations is not clearly documented and understood, specific indicators, such as extreme poverty, show that vulnerability among women is pervasive. Women in low and middle-income countries often do not control economic resources and are culturally disadvantaged, which exacerbates other vulnerabilities they experience. In this commentary, we explore the different understandings of vulnerability and the importance of engaging communities in defining vulnerability for research, as well as for programming and provision of maternal newborn and child health (MNCH) services. Methodology: In a recent community-based qualitative study, we examined the healthcare utilization experiences of vulnerable women with MNCH services in rural southwestern Uganda. Focus group discussions were conducted with community leaders and community health workers in two districts of Southwestern Uganda. In addition, we did individual interviews with women living in extreme poverty and having other conventional vulnerability characteristics. Findings and discussion: We found that the traditional criteria of vulnerability were insufficient to identify categories of vulnerable women to target in the context of MNCH programming and service provision in resourcelimited settings. Through our engagement with communities and through the narratives of the people we interviewed, we obtained insight into how nuanced vulnerability can be, and how important it is to ground definitions of vulnerability within the specific context. We identified additional aspects of vulnerability through this study, including: women who suffer from alcoholism or have husbands with alcoholism, women with a history of home births, women that have given birth only to girls, and those living on fishing sites. Conclusion: Engaging communities in defining vulnerability is critical for the effective design, implementation and monitoring of MNCH programs, as it ensures these services are reaching those who are most in need.Item Dramatic effects of COVID-19 public health measures and mass reverse migration on youth sexual and reproductive health in rural Uganda(Paediatrics & Child Health,, 2022) Khan, Sundus; Kemigisha, Elizabeth; Turyakira, Eleanor; Chaput, Kathleen; Kabakyenga, Jerome; Kyomuhangi, Teddy; Manalili, Kimberly; Brenner, Jennifer L.Introduction: Youth (aged 10 to 24 years) comprise nearly one-third of Uganda’s population and often face challenges accessing sexual and reproductive health (SRH) services, with a disproportionately high incidence of negative SRH outcomes. Responding to COVID-19, Uganda implemented strict public health measures including broad public transportation, schooling, and business shut-downs, causing mass reversemigration of youth from urban schools and workplaces back to rural home villages. Our study aimed to qualitatively describe the perceived unintended impacts of COVID-19 health measures on youth SRH in two rural districts. Methods: Semi-structured focus group discussions (FGD) and key informant interviews (KII) with purposively selected youth, parents, community leaders, community health worker (CHW) coordinators and supervisors, health providers, facility and district health managers, and district health officers were conducted to explore lived experiences and impressions of the impacts of COVID-19 measures on youth SRH. Interviews were recorded, transcribed, and coded using deductive thematic analysis. Results: Four COVID-19-related themes and three subthemes resulted from 15 FGDs and 2 KIIs (n=94). Public transportation shutdown and mandatory mask-wearing were barriers to youth SRH care-seeking. School/workplace closures and subsequent urban youth migration back to rural homes increased demand at ill-prepared, rural health facilities, further impeding care-seeking. Youth reported fear of discovery by parents, which deterred SRH service seeking. Lockdown led to family financial hardship, isolation, and overcrowding; youth mistreatment, gender-based violence, and forced marriage ensued with some youth reportedly entering partnerships as a means of escape. Idleness and increased social contact were perceived to lead to increased and earlier sexual activity. Reported SRH impacts included increased severity of infection and complications due to delayed care seeking, and surges in youth sexually transmitted infections, pregnancy, and abortion. Conclusion: COVID-19 public health measures reportedly reduced youth care seeking while increasing risky behaviours and negative SRH outcomes. Investment in youth SRH programming is critical to reverse unintended pandemic effects and regain momentum toward youth SRH targets. Future pandemic management must consider social and health disparities, and mitigate unintended risks of public health measures to youth SRH.Item Effect of Age at Initiation of Antiretroviral Therapy on Treatment Outcomes; A Retrospective Cohort study at a large HIV Clinic in Southwestern Uganda(Plos one, 2018) Ssebutinde, Peter; Kyamwanga, Imelda T.; Turyakira, Eleanor; Asiimwe, Stephen; Bajunirwe, FrancisThe prevalence of HIV infection among older persons is increasing yet older age at initiation of antiretroviral therapy (ART) may be associated with poorer treatment outcomes including mortality. However, majority of these studies have been done in the western world and there is limited data in resource limited settings. Our study used routinely collected health facility data to assess trends in age at initiation of ART, the effect of age at ART initiation on mortality and immunological response at a large urban hospital in south western Uganda.We conducted a retrospective records review of patients attending the HIV clinic at Mbarara Regional Referral Hospital in western Uganda. We retrieved records for 8,533 patients who started ART between January 2006 and December 2012. Their data had been collected and stored as part of the larger International Epidemiological Database for the Evaluation of AIDS (IeDEA). Age was stratified into three categories namely; 18–34 (young adults), 35–49 (mid-age) and 50 years or older (older adults). Survival analysis procedures with Kaplan-Meier’s plots were used to calculate the survival probability with mortality as the endpoint and Poisson regression analysis used to determine the adjusted relative risks (RR) of mortality.The proportion of young adults and patients at WHO stage I initiating ART increased steadily over the 7-year period. Older age at ART initiation (> = 50 years) was associated with a higher risk of mortality with adjusted relative risk (RR) at 1.63, (95% CI 1.26–2.11) compared to younger age. Male gender, WHO stages III and IV, lower CD4 count and lower body mass index were also all independently and significantly associated with higher risk for mortality. Older adults also had a poorer immunological response RR = 1.79 (95% CI 0.89–3.58) but was not statistically significant.Following ART initiation, older adults compared to the young, have a higher risk of mortality. This age group should be targeted first for ‘screen and treat’ approach. Optimization of ART treatment regimens for this age group is also required to reduce mortality and improve immunological response.Item The Experience and Impact of Contraceptive Stockouts Among Women, Providers and Policymakers in Two Districts of Uganda(Guttmacher Institute, 2016) Grindlay, Kate; Turyakira, Eleanor; Kyamwanga, Imelda T.; Nickerson, Adrianne; Blanchard, KellyLittle is known about the impact of contraceptive stockouts on women and health care providers, or how policymakers perceive and handle such stockouts. METHODS: In May–July 2015, a qualitative study on experiences of contraceptive stockouts was conducted in two districts of Uganda. It comprised three data collection components: eight focus groups with 50 women, 24 individual in-depth interviews with family planning service providers and facility managers, and 11 in-depth interviews with district-level policymakers and decision makers. Data analysis followed the content analysis approach. RESULTS: Contraceptive stockouts were common, particularly for long-term methods and oral contraceptives. For women, the consequences included stress, increased costs, domestic conflict, and unwanted or unplanned pregnancies. Providers reported emotional distress, blame from clients, deterioration of skills and lower demand for their services as a result of stockouts; they also felt unable to address stockouts under current supply systems. Despite the widespread prevalence and adverse impact of stockouts, policymakers reported being unaware of the scope of the problem. CONCLUSIONS: The findings suggest there is a critical need to raise awareness of the issue, reduce stockouts and mitigate their negative consequences. Efforts to eliminate stockouts should include addressing supply chain issues. Raising community awareness and engaging with men on family planning may be ways to deal with the consequences of stockouts.Item Five-year retention of volunteer community health workers in rural Uganda: a population-based retrospective cohort(Health policy and planning, 2022) Hobbs, Amy J.; Manalili, Kimberly; Turyakira, Eleanor; Kabakyenga, Jerome; Kyomuhangi, Teddy; Nettel-Aguirre, Alberto; Kyokushaba, Clare; Rwandekeye, Polar; Brenner, Jennifer L.Community health workers (CHWs) effectively improve maternal, newborn and child health (MNCH) outcomes in low-to-middle-income countries. However, CHW retention remains a challenge. This retrospective registry analysis evaluated medium-term retention of volunteer CHWs in two rural Ugandan districts, trained during a district-wide MNCH initiative. From 2012 to 2014, the Healthy Child Uganda partnership facilitated district-led CHW programme scale-up. CHW retention was tracked prospectively from the start of the intervention up to 2 years. Additional follow-up occurred at 5 years to confirm retention status. Database analysis assessed CHW demographic characteristics, retention rates and exit reasons 5 years post-intervention. A multivariable logistic regression model examined 5-year retention-associated characteristics. Of the original cohort of 2317 CHWs, 70% were female. The mean age was 38.8 years (standard deviation, SD: 10.0). Sixty months (5 years) after the start of the intervention, 84% of CHWs remained active. Of those exiting (n=377), 63% reported a ‘logistical’ reason, such as relocation (n=96), new job (n=51) or death (n=30). Sex [male, female; odds ratio (OR)=1.53; 95% confidence interval (CI): 1 · 20–1 · 96] and age group (<25 years, 30–59; OR=0.40; 95% CI: 0.25–0.62) were significantly associated with 5-year retention in multivariable modelling. Education completion (secondary school, primary) was not significantly associated with retention in adjusted analyses. CHWs in this relatively large cohort, trained and supervised within a national CHW programme and district-wide MNCH initiative, were retained over the medium term. Importantly, high 5-year retention in this intervention counters findings from other studies suggesting low retention in government-led and volunteer CHW programmes. Encouragingly, findings from our study suggest that retention was high, not significantly associated with timing of external partner support and largely not attributed to the CHW role i.e. workload and programme factors. Our study showcases the potential for sustainable volunteer CHW programming at scale and can inform planners and policymakers considering programme design, including selection and replacement planning for CHW networks.Item Heterogeneous decrease in malaria prevalence in children over a six-year period in south-western Uganda(Malaria journal, 2011) De Beaudrap, Pierre; Nabasumba, Carolyn; Grandesso, Francesco; Turyakira, Eleanor; Schramm, Birgit; Boum, Yap; Etard, Jean-FrançoisMalaria is a major public health problem, especially for children. However, recent reports suggest a decline in the malaria burden. The aim of this study was to assess the change in the prevalence of malaria infection among children below five years of age between 2004 and 2010 in a mesoendemic area of Uganda and to analyse the risk factors of malaria infection. Methods: Two cross-sectional surveys were conducted in 2004 and in 2010 at the end of the rainy and dry seasons to measure the prevalence of P. falciparum infection among children less than five years of age. Rapid diagnostic tests and blood smears were used to diagnose malaria infection. In 2010, sampling was stratified by urban and rural areas. In each selected household, knowledge of malaria and bed nets, and bed net ownership and use, were assessed. Results: In 2004 and 2010, respectively, a total of 527 and 2,320 (999 in the urban area and 1,321 in rural areas) children less than five years old were enrolled. Prevalence of malaria infection declined from 43% (95% CI: 34-52) in 2004, to 23% (95% CI: 17-30) in rural areas in 2010 and 3% (95% CI: 2-5) in the urban area in 2010. From the rainy to dry season in 2010, prevalence decreased from 23% to 10% (95% CI: 6-14) in rural areas (P = 0.001) and remained stable from 3% to 4% (95% CI: 1-7) in the urban area (P = 0.9). The proportion of households reporting ownership and use of at least one bed net increased from 22.9% in 2004 to 64.7% in the urban area and 44.5% in rural areas in 2010 (P < 0.001). In 2010, the risk of malaria infection was consistently associated with child age and household wealth. In rural areas, malaria infection was also associated with geographic factors. Conclusions: This study reports a significant drop in the prevalence of malaria infection among children below five years of age, paralleled by an uptake in bed-net use. However, prevalence remains unacceptably high in rural areas and is strongly associated with poverty.Item Impact of malaria during pregnancy on pregnancy outcomes in a Ugandan prospective cohort with intensive malaria screening and prompt treatment(Malaria journal, 2013) De Beaudrap, Pierre; Turyakira, Eleanor; White, Lisa J.; Nabasumba, Carolyn; Tumwebaze, Benon; Muehlenbachs, Atis; Guérin, Philippe J.; Boum, Yap; McGready, Rose; Piola, PatriceMalaria in pregnancy (MiP) is a major public health problem in endemic areas of sub-Saharan Africa and has important consequences on birth outcome. Because MiP is a complex phenomenon and malaria epidemiology is rapidly changing, additional evidence is still required to understand how best to control malaria. This study followed a prospective cohort of pregnant women who had access to intensive malaria screening and prompt treatment to identify factors associated with increased risk of MiP and to analyse how various characteristics of MiP affect delivery outcomes. Methods: Between October 2006 and May 2009, 1,218 pregnant women were enrolled in a prospective cohort. After an initial assessment, they were screened weekly for malaria. At delivery, blood smears were obtained from the mother, placenta, cord and newborn. Multivariate analyses were performed to analyse the association between mothers’ characteristics and malaria risk, as well as between MiP and birth outcome, length and weight at birth. This study is a secondary analysis of a trial registered with ClinicalTrials.gov, number NCT00495508. Results: Overall, 288/1,069 (27%) mothers had 345 peripheral malaria infections. The risk of peripheral malaria was higher in mothers who were younger, infected with HIV, had less education, lived in rural areas or reported no bed net use, whereas the risk of placental infection was associated with more frequent malaria infections and with infection during late pregnancy. The risk of pre-term delivery and of miscarriage was increased in mothers infected with HIV, living in rural areas and with MiP occurring within two weeks of delivery. In adjusted analysis, birth weight but not length was reduced in babies of mothers exposed to MiP (−60g, 95%CI: -120 to 0 for at least one infection and -150 g, 95%CI: -280 to −20 for >1 infections). Conclusions: In this study, the timing, parasitaemia level and number of peripherally-detected malaria infections, but not the presence of fever, were associated with adverse birth outcomes. Hence, prompt malaria detection and treatment should be offered to pregnant women regardless of symptoms or other preventive measures used during pregnancy, and with increased focus on mothers living in remote areasItem Increasing incidence of pregnancy among women receiving HIV care and treatment at a large urban facility in western Uganda(Reproductive health, 2014) Kabami, Jane; Turyakira, Eleanor; Biraro, Sam; Bajunirwe, FrancisAntiretroviral treatment restores physical functioning and may have an impact on fertility desires. Counseling is given to HIV positive women to create awareness and to provide information on pregnancy and delivery. The purpose of this study was to determine the incidence of pregnancy and factors that predict pregnancy among women of reproductive age receiving HIV care and treatment at a large urban center in western Uganda.We conducted a retrospective cohort study using routinely collected data at the Immune Suppression (ISS) Clinic of Mbarara Regional Referral Hospital located in Mbarara District, western Uganda collected between January 2006 and June 2010. Women aged 15 to 50 years were eligible for analysis. The primary outcome was incidence of pregnancy calculated as number of pregnancies per 1000 person years (PY). Data was analyzed by calendar year and year of enrolment and used survival analysis to determine the predictors of pregnancy.A total of 3144 women were included with a median follow up of 12.5 months. The overall incidence rate was 90.7 pregnancies per 1000 person years. Incidence increased from 29.8 pregnancies per 1000 PY in 2006 to 122 pregnancies per 1000 PY in 2010 (p < 0.001). Significant predictors for pregnancy were younger age (HR 10.96 95% CI 3.22-37.2), married (HR 2.09 95% CI 1.69-2.64) and single (HR 1.95 95% CI 1.34-2.84) compared to widowed or separated, primary education (HR 1.65 95% CI 1.02-2.66), not knowing the HIV status of the spouse (HR 1.46, 95%CI 1.13-1.93) compared to knowing. The use of family planning (HR 0.23 95% CI 0.18- 0.30) and an increase in CD4 count between baseline and most recent count were protective against pregnancy. ART use was not a significant predictor.Incidence of pregnancy among women receiving routine HIV care and treatment has increased and is almost comparable to that in the general population. Thus routine HIV care should integrate reproductive health needs for these women.Item Individual and health facility factors and the risk for obstructed labour and its adverse outcomes in south-western Uganda(BMC pregnancy and childbirth, 2011) Kabakyenga, Jerome K.; Östergren, Per-Olof; Turyakira, Eleanor; Mukasa, Peter K.; Pettersson, Karen O.Obstructed labour is still a major cause of maternal morbidity and mortality and of adverse outcome for newborns in low-income countries. The aim of this study was to investigate the role of individual and health facility factors and the risk for obstructed labour and its adverse outcomes in south-western Uganda. Methods: A review was performed on 12,463 obstetric records for the year 2006 from six hospitals located in south-western Uganda and 11,180 women records were analysed. Multivariate logistic regression analyses were applied to control for probable confounders. Results: Prevalence of obstructed labour for the six hospitals was 10.5% and the main causes were cephalopelvic disproportion (63.3%), malpresentation or malposition (36.4%) and hydrocephalus (0.3%). The risk of obstructed labour was statistically significantly associated with being resident of a particular district [Isingiro] (AOR 1.39, 95% CI: 1.04-1.86), with nulliparous status (AOR 1.47, 95% CI: 1.22-1.78), having delivered once before (AOR 1.57, 95% CI: 1.30-1.91) and age group 15-19 years (AOR 1.21, 95% CI: 1.02-1.45). The risk for perinatal death as an adverse outcome was statistically significantly associated with districts other than five comprising the study area (AOR 2.85, 95% CI: 1.60-5.08) and grand multiparous status (AOR 1.89, 95% CI: 1.11-3.22). Women who lacked paid employment were at increased risk of obstructed labour. Perinatal mortality rate was 142/1000 total births in women with obstructed labour compared to 65/1000 total births in women without the condition. The odds of having maternal complications in women with obstructed labour were 8 times those without the condition. The case fatality rate for obstructed labour was 1.2%. Conclusions: Individual socio-demographic and health system factors are strongly associated with obstructed labour and its adverse outcome in south-western Uganda. Our study provides baseline information which may be used by policy makers and implementers to improve implementation of safe motherhood programmes.Item Influence of Birth Preparedness, Decision-Making on Location of Birth and Assistance by Skilled Birth Attendants among Women in South-Western Uganda(PloS one, 2012) Kabakyenga, Jerome K.; Ostergren, Per-Olof; Turyakira, Eleanor; Pettersson, Karen O.Introduction: Assistance by skilled birth attendants (SBAs) during childbirth is one of the strategies aimed at reducing maternal morbidity and mortality in low-income countries. However, the relationship between birth preparedness and decision-making on location of birth and assistance by skilled birth attendants in this context is not well studied. The aim of this study was to assess the influence of birth preparedness practices and decision-making and assistance by SBAs among women in south-western Uganda. Methods: Community survey methods were used to identify 759 recently delivered women from 120 villages in rural Mbarara district. Interviewer-administered questionnaires were used to collect data. Logistic regression analyses were conducted to assess the relationship between birth preparedness, decision-making on location of birth and assistance by SBAs. Results: 35% of the women had been prepared for childbirth and the prevalence of assistance by SBAs in the sample was 68%. The final decision regarding location of birth was made by the woman herself (36%), the woman with spouse (56%) and the woman with relative/friend (8%). The relationships between birth preparedness and women decision-making on location of birth in consultation with spouse/friends/relatives and choosing assistance by SBAs showed statistical significance which persisted after adjusting for possible confounders (OR 1.5, 95% CI: 1.0–2.4) and (OR 4.4, 95% CI: 3.0–6.7) respectively. Education, household assets and birth preparedness showed clear synergistic effect on the relationship between decision-maker on location of birth and assistance by SBAs. Other factors which showed statistical significant relationships with assistance by SBAs were ANC attendance, parity and residence. Conclusion: Women’s decision-making on location of birth in consultation with spouse/friends/relatives and birth preparedness showed significant effect on choosing assistance by SBAs at birth. Education and household assets ownership showed a synergistic effect on the relationship between the decision-maker and assistance by SBAs.Item Knowledge of obstetric danger signs and birth preparedness practices among women in rural Uganda(Reproductive health, 2011) Kabakyenga, Jerome K.; Östergren, Per-Olof; Turyakira, Eleanor; Pettersson, Karen O.Improving knowledge of obstetric danger signs and promoting birth preparedness practices are strategies aimed at enhancing utilization of skilled care in low-income countries. The aim of the study was to explore the association between knowledge of obstetric danger signs and birth preparedness among recently delivered women in south-western Uganda. Methods: The study included 764 recently delivered women from 112 villages in Mbarara district. Community survey methods were used and 764 recently delivered women from 112 villages in Mbarara district were included in study. Interviewer administered questionnaire were used to collect data. Logistic regression analyses were conducted to explore the relationship between knowledge of key danger signs and birth preparedness. Results: Fifty two percent of women knew at least one key danger sign during pregnancy, 72% during delivery and 72% during postpartum. Only 19% had knowledge of 3 or more key danger signs during the three periods. Of the four birth preparedness practices; 91% had saved money, 71% had bought birth materials, 61% identified a health professional and 61% identified means of transport. Overall 35% of the respondents were birth prepared. The relationship between knowledge of at least one key danger sign during pregnancy or during postpartum and birth preparedness showed statistical significance which persisted after adjusting for probable confounders (OR 1.8, 95% CI: 1.2-2.6) and (OR 1.9, 95% CI: 1.2-3.0) respectively. Young age and high levels of education had synergistic effect on the relationship between knowledge and birth preparedness. The associations between knowledge of at least one key danger sign during childbirth or knowledge that prolonged labour was a key danger sign and birth preparedness were not statistically significant. Conclusions: The prevalence of recently delivered women who had knowledge of key danger signs or those who were birth prepared was very low. Since the majority of women attend antenatal care sessions, the quality and methods of delivery of antenatal care education require review so as to improve its effectiveness. Universal primary and secondary education programmes ought to be promoted so as to enhance the impact of knowledge of key danger signs on birth preparedness practicesItem Loss to follow-up and associated maternal factors among HIV-exposed infants at the Mbarara Regional Referral Hospital, Uganda: a retrospective study(BMC Infectious Diseases, 2020) Ankunda, Rogers; Cumber, Samuel N.; Atuhaire, Catherine; Kabanda, Taseera; Nkfusai, Claude N.; Wirsiy, Frankline S.; Turyakira, EleanorLoss to follow-up (LTFU) deprives HIV-exposed infants the lifesaving care required and results in exposing HIV free infants to virus requisition risk. We aimed to determine the rate of LTFU, postnatal mother-tochild HIV-transmission (MTCT) and to identify maternal factors associated with LTFU among HIV-exposed infants enrolled at Mbarara Regional Referral Hospital PMTCT clinic. Methods: Study participants were infants born to HIV-positive mothers enrolled in the PMTCT clinic for HIV care at Mbarara Regional Referral Hospital. While access database in the Early Infant Diagnosis (EID) clinic provided data on infants, the open medical record system database at the ISS clinic provided that for mothers. Infants were classified as LTFU if they had not completed their follow-up schedule by 18 months of age. At 18 months, an infant is expected to receive a rapid diagnostic test before being discharged from the PMTCT clinic. Postnatal MTCT of HIV was calculated as a proportion of infants followed and tested from birth to 18 months of age. Logistic regression was used to determine possible associations between mothers’ characteristics and LTFU. In-depth interviews of mothers of LTFU infants and health workers who attend to the HIV-exposed infants were carried out to identify factors not captured in the electronic database. Results: Out of 1624 infants enrolled at the clinic, 533 (33%) were dropped for lack of mother’s clinic identification number, 18 (1.1%) were either dead or transferred out. Out of 1073 infants analysed, 515 (48%) were LTFU by 18 months of age while out of the 558 who completed their follow-up schedule, 20 (3.6%) tested positive for HIV. Young age of mother, far distance to hospital and non-use of family planning were identified as outstanding factors responsible for LTFU. In addition, in-depth interviews revealed facility-level factors such as “waiting time” which would not be found in routine client databases.Item Population pharmacokinetics of Artemether and dihydroartemisinin in pregnant women with uncomplicated Plasmodium falciparum malaria in Uganda(Malaria journal, 2012) Tarning, Joel; Kloprogge, Frank; Piola, Patrice; Dhorda, Mehul; Muwanga, Sulaiman; Turyakira, Eleanor; Nuengchamnong, Nitra; Nosten, François; Day, Nicholas P.J.; White, Nicholas J.; Guerin, Philippe J.; Lindegardh, NiklasMalaria in pregnancy increases the risk of maternal anemia, abortion and low birth weight. Approximately 85.3 million pregnancies occur annually in areas with Plasmodium falciparum transmission. Pregnancy has been reported to alter the pharmacokinetic properties of many anti-malarial drugs. Reduced drug exposure increases the risk of treatment failure. The objective of this study was to evaluate the population pharmacokinetic properties of artemether and its active metabolite dihydroartemisinin in pregnant women with uncomplicated P. falciparum malaria in Uganda. Methods: Twenty-one women with uncomplicated P. falciparum malaria in the second and third trimesters of pregnancy received the fixed oral combination of 80 mg artemether and 480 mg lumefantrine twice daily for three days. Artemether and dihydroartemisinin plasma concentrations after the last dose administration were quantified using liquid chromatography coupled to tandem mass-spectroscopy. A simultaneous drug-metabolite population pharmacokinetic model for artemether and dihydroartemisinin was developed taking into account different disposition, absorption, error and covariate models. A separate modeling approach and a non-compartmental analysis (NCA) were also performed to enable a comparison with literature values and different modeling strategies. Results: The treatment was well tolerated and there were no cases of recurrent malaria. A flexible absorption model with sequential zero-order and transit-compartment absorption followed by a simultaneous one-compartment disposition model for both artemether and dihydroartemisinin provided the best fit to the data. Artemether and dihydroartemisinin exposure was lower than that reported in non-pregnant populations. An approximately four-fold higher apparent volume of distribution for dihydroartemisinin was obtained by non-compartmental analysis and separate modeling compared to that from simultaneous modeling of the drug and metabolite. This highlights a potential pitfall when analyzing drug/metabolite data with traditional approachesItem Potential for Revitalisation of the Diaphragm for Family Planning in Uganda: A Rapid Assessment of the Feasibility of Introducing the SILCS Diaphragm(African Journal of Reproductive Health, 2014) Kyamwanga, Imelda T.; Turyakira, Eleanor; Kilbourne-Brook, Maggie; Coffey, Patricia S.This health systems assessment evaluated the feasibility of introducing a new contraceptive device, the SILCS single-size diaphragm, into the existing family planning method mix in Uganda. A total of 26 focus group discussions with 201 female and 77 male potential users and 98 key informant interviews with policymakers and providers were conducted between June and August 2010. Potential users, providers, and policymakers recognised that the SILCS Diaphragm could fill a gap in the method mix and expressed eagerness to make the SILCS Diaphragm available, particularly because it is nonhormonal and woman initiated. The diaphragm was viewed by all stakeholders as a method that would increase choice and could improve women’s reproductive health in Uganda. Like many countries, Uganda’s family planning programme is financially stretched, and clear support for the SILCS Diaphragm by end-users will need to be demonstrated before the product will be considered for public-sector introduction.

We assessed the factors associated with sleeping under costfree mosquito nets among children under-five years in Nyakayojo sub-county, Mbarara District, Uganda. Methods: 381 households with at least a child under-five years and benefited from cost-free bed nets in Nyakayojo were randomly selected. Caregivers of children were interviewed using a questionnaire. Results: 74% children slept under bed nets a night before the study. Children from households with ≥2 nets [aOR=1.75; 95% CI: 1.09-2.81, p=0.02], female caregiver [aOR=2.11; 95% CI: 1.16-3.79, p=0.01] and children from households that did not face problems (skin irritation, torn nets, suffocation, night sweating, nasal congestion and candle fire) when sleeping under bed nets [aOR=1.81; 95% CI: 1.10-2.98, p=0.02] were more likely to use nets. Main reason for not sleeping under a net was damage to the net (47.1%). Conclusion: The proportion of children sleeping under nets was comparable to MDG target. Improvements in use of mosquito nets by children can be achieved through increasing number of nets in a household.Item Prevalence of hypertension in relation to anthropometric indices among secondary adolescents in Mbarara, Southwestern Uganda(Italian Journal of Pediatrics, 2020) Katamba, Godfrey; Agaba, David C.; Migisha, Richard; Namaganda, Agnes; Namayanja, Rosemary; Turyakira, EleanorStudies investigating the prevalence of hypertension and its correlation with anthropometric indices among adolescents are still scarce compared to those conducted in adults of greater than 40 years. So far, no other study estimating the prevalence and correlates of hypertension among adolescents in Uganda has been found. Objective: The purpose of this study, therefore, was to asses the prevalence of hypertension and its correlation with anthropometric indices among adolescents in Mbarara Municipality, southwestern Uganda. Methods: A cross-sectional study was carried out among 616 secondary school adolescents aged 12–19 years in Mbarara Municipality, Uganda. Blood pressure and anthropometric indices were determined by standard methods. In the statistical analysis, linear regression analysis was done to assess the relationship between blood pressure and anthropometric indices. Results: Overall prevalence of hypertension among adolescents was at 3.1% (n = 19) while prehypertension was 7.1% (n = 44). There was a statistically significant correlation between blood pressure, neck circumference, waist to hip ratio and body mass index at bivariate analysis. In multivariate analysis for anthropometric indices and sex, only neck circumference remained significantly correlated with blood pressure (p < 0.05). Conclusion: The prevalence of hypertension among adolescents in the study setting was low. An increase in neck circumference results in an increase in blood pressure among adolescents.Item Risk factors for human anthrax outbreak in Kiruhura District, Southwestern Uganda: a population-based case control study(PAMJ - One Health, 2021) Migisha, Richard; Mbatidde, Irene; Agaba, David C.; Turyakira, Eleanor; Tumwine, Gabriel; Byaruhanga, Aggrey; Siya, Aggrey; Ruzaaza, Gad N.; Kirunda, HalidIntroduction: in 2018, Uganda experienced recurrent outbreaks of anthrax in both humans and livestock. We aimed to determine risk factors for human anthrax outbreak among residents of Kazo County, Kiruhura District, south-western Uganda. Methods: we conducted an unmatched case control study during March-April 2019. We defined a case as having had anthrax infection reported to be diagnosed by a healthcare worker in a resident of Kazo County between May 1st, 2018 and June 1st, 2018. A control was a resident in the nearest neighboring household who had not been diagnosed with anthrax between May 1st and June 1st and who had no symptoms suggestive of anthrax in May 2018. We obtained participants' sociodemographic, clinical and exposure characteristics using a structured questionnaire. We performed logistic regression to identify risk factors for human anthrax. Results: we recruited 101 participants (28 cases and 73 controls) with median age of 34 (IQR; 26-47) years; most (61.4%) were female. The overall attack rate was 1.9%, while the most common clinical manifestations were ulcers (96.4%) and fever (96.4%). The risk factors for contracting human anthrax were: slaughtering of anthrax infected animals (aOR=5.74; 95%CI: 1.39-23.8), consuming of anthrax infected meat (aOR=6.4; 95%CI: 1.53- 6.7) and being male (aOR=12.8; 95%CI: 3.31-49.1).
