Maternal genitourinary infections and poor nutritional status increase risk of preterm birth in Gasabo District, Rwanda: a prospective, longitudinal, cohort study.

BACKGROUND: Preterm birth (PTB) is a leading cause of early childhood mortality and morbidity, including long-term physical and mental impairment. The risk factors for PTB are complex and include maternal nutritional status and infections. This study aimed to identify potentially modifiable risk factors for targeted interventions to reduce the occurrence of PTB in Rwanda. METHODS: We conducted a prospective, longitudinal cohort study of healthy pregnant women aged 18 to 49 years. Women at 9-15 gestational weeks were recruited from 10 health centers in Gasabo District, Kigali Province between September and October 2017. Pregnancy age was estimated using ultrasonography and date of last menstruation. Anthropometric and laboratory measurements were performed using standard procedures for both mothers and newborns. Surveys were administered to assess demographic and health histories. Categorical and continuous variables were depicted as proportions and means, respectively. Variables with p <  0.25 in bivariate analyses were included in multivariable logistic regression models to determine independent predictors of PTB. The results were reported as odds ratios (ORs) and 95% confidence intervals (CI), with statistical significance set at p <  0.05. RESULTS: Among 367 participants who delivered at a mean of 38.0 ± 2.2 gestational weeks, the overall PTB rate was 10.1%. After adjusting for potential confounders, we identified the following independent risk factors for PTB: anemia (hemoglobin < 11 g/dl) (OR: 4.27; 95%CI: 1.85-9.85), urinary tract infection (UTI) (OR:9.82; 95%CI: 3.88-24.83), chlamydia infection (OR: 2.79; 95%CI: 1.17-6.63), inadequate minimum dietary diversity for women (MDD-W) score (OR:3.94; CI: 1.57-9.91) and low mid-upper arm circumference (MUAC) < 23 cm (OR: 3.12, 95%CI; 1.31-7.43). indicators of nutritional inadequacy (low MDD-W and MUAC) predicted risk for low birth weight (LBW) but only UTI was associated with LBW in contrast with PTB. CONCLUSION: Targeted interventions are needed to improve the nutritional status of pregnant women, such as maternal education on dietary diversity and prevention of anemia pre-pregnancy. Additionally, prevention and treatment of maternal infections, especially sexually transmitted infections and UTIs should be reinforced during standard antenatal care screening which currently only includes HIV and syphilis testing.

Association between micronutrients and maternal leukocyte telomere length in early pregnancy in Rwanda.

BACKGROUND: Exposure to environmental stressors can lead to shorter leukocyte telomere length and increase the risk of chronic diseases. Preservation of leukocyte telomere length by reducing oxidative stress exposure and reinforcing immunity may be a mechanism by which nutritional factors delay or prevent chronic disease development. METHODS: Healthy pregnant women (aged 18-45 years) at 9-15 weeks of gestation living in Gasabo District, Kigali, Rwanda, were recruited from 10 health centers for a prospective, longitudinal study from September to October 2017 to determine possible associations between nutrition health, infectious disease and leukocyte telomere length. Anthropometric and laboratory measurements were performed using standard procedures; sociodemographic parameters and health histories were assessed via surveys, and leukocyte telomere length was assessed using quantitative PCR expressed as the ratio of a telomeric product to a single-copy gene product (T/S). RESULTS: Mean gestational age of participants (n = 297) at enrollment was 13.04 ± 3.50 weeks, age was 28.16 ± 6.10 years and leukocyte telomere length was 1.16 ± 0.22 (T/S). Younger age; no schooling vs. primary schooling; and lower levels of ferritin, soluble transferrin receptors and retinol-binding protein were independent predictors of longer telomere length in multivariable models. CONCLUSIONS: Leukocyte telomere length is an indicator of biological aging in pregnant Rwandan women. Maternal micronutrient status, specifically lower ferritin, soluble transferrin receptor levels, and retinol-binding protein levels were associated with longer maternal telomere length in contrast with some studies from North America and Europe. There were no associations between inflammation and infectious disease status and maternal leukocyte telomere length. Further studies are needed to enhance our understanding of the interplay between maternal nutritional status and infectious disease in relation to leukocyte telomere length in developing countries.

Point of care ultrasound: does the presence of ascites in severe pre-eclampsia correlate with poor maternal and neonatal outcome?

OBJECTIVE: Ascites in severe pre-eclampsia may impact foetal and maternal outcomes. The objective was to determine the prevalence of ascites in women with severe pre-eclampsia by point of care (POC) ultrasound and to determine whether it correlates with higher perinatal risks. METHODS: Prospective cohort study of patients admitted with severe pre-eclampsia at 2 teaching hospitals in Kigali, Rwanda. Serial POC ultrasound was performed to document ascites. Patients were stratified by the presence of ascites in perinatal period. Maternal demographics and complications were recorded and compared between groups. RESULTS: There were 112 patients with severe pre-eclampsia, and ascites was found in 53.5% (76.7% antepartum, and 23.3% postpartum). Antepartum ascites correlated with an earlier delivery (32.2 ± 0.51 vs. 33.8 ± 0.47 weeks, P = 0.022) as well as lower birthweight (1587.3 ± 77.03 vs. 2011.6 ± 103.5 g, P = 0.002). Antepartum ascites was associated with higher stillbirth rates (P = 0.034) and NICU admission (87.2% vs. 68%, P = 0.034). Maternal hospital stay was increased in the ascites group (P < 0.0001). CONCLUSIONS: Ascites is common in severe pre-eclampsia in Rwanda and maybe a prognosticator for poor outcomes. A larger sample is necessary to determine whether ascites is independently associated with maternal morbidity and mortality and whether documenting its presence aids in the management of the foetus and mother.

OBJECTIF: L'ascite dans la pré-éclampsie sévère peut avoir un impact sur les résultats pour le fœtus et la mère. L'objectif était de déterminer la prévalence de l'ascite chez les femmes présentant une échographie de pré-éclampsie sévère au point des soins et de déterminer si elle corrélait avec des risques périnataux plus élevés. MÉTHODES: Etude de cohorte prospective de patientes admises avec une pré-éclampsie sévère dans deux hôpitaux universitaires de Kigali, au Rwanda. Une échographie au point des soins a été réalisée en série pour documenter l'ascite. Les patientes ont été stratifiées en fonction de la présence d'ascite en période périnatale. Les données démographiques maternelles et les complications ont été enregistrées et comparées entre les groupes. RÉSULTATS: Il y avait 112 patientes atteintes de pré-éclampsie sévère et l'ascite a été trouvé chez 53,5% (76,7% antépartum et 23,3% postpartum). L'ascite antépartum corrélait avec un accouchement antérieur (32,2 ± 0,51 vs 33,8 ± 0,47 semaines, p = 0,022) ainsi qu'avec un poids à la naissance plus faible (1587,3 ± 77,03 vs 2011,6 ± 103,5 g, p = 0,002). L'ascite antépartum était associée à des taux de mortinatalité plus élevés (p = 0,034) et à une admission en USIN-US (87,2% contre 68%, p = 0,034). Le séjour à l'hôpital de la mère était augmenté dans le groupe ascite (p <0,0001). CONCLUSIONS: L'ascite est fréquente dans la pré-éclampsie sévère au Rwanda et peut être un pronostic pour des résultats médiocres. Un échantillon plus important est nécessaire pour déterminer si l'ascite est associée de manière indépendante à la morbidité et à la mortalité maternelles et si la documentation de sa présence facilite la prise en charge du fœtus et de la mère.

Reproductive health among women of child-bearing age after surgery for Rheumatic Heart Disease in Rwanda.

OBJECTIVE: To determine maternal and fetal outcomes in postoperative women with RHD who become pregnant after valve surgery and evaluate current anticoagulation management during pregnancy. METHODS: Data from the Rwandan RHD cardiac surgical registry identified all female patients who underwent valve surgery before or during childbearing age since 2006. 136 participants completed a mixed-methods questionnaire detailing each pregnancy after surgery, including anticoagulation regimen and outcomes. RESULTS: 38.2% (n=136) of patients reported at least one pregnancy after surgery, of which more than half were unintentional (53.9%, n=52). Among those with mechanical valves, most remained on warfarin alone during pregnancy (58.5%, n=53) while one third were switched to low molecular weight heparin during the first, second, or third trimesters (5 vs. 4 vs. 7, n=18). Women with bioprosthetic valve replacement or valve repair were more likely to experience live term births (84.6% vs 45.3%, p<0.01) and less likely to report spontaneous abortion (3.9% vs 30.2%, p<0.01) compared to women with mechanical valve replacement. Excessive bleeding was the most common complication during pregnancy (9.1%, n=79), and two infants were diagnosed with congenital defects associated with warfarin embryopathy (4.8%, n=42). CONCLUSIONS: Despite preoperative counseling discouraging conception, many women with prosthetic valves still become pregnant after surgery. The results of this study will inform evidence-based and context-specific practices for anticoagulation during pregnancy in Rwanda and the region.

Challenges in updating national guidelines and essential medicines lists in Sub-Saharan African countries to include WHO-recommended postpartum hemorrhage medicines.

Despite the 2017 WHO recommendations on tranexamic acid (TXA) for the treatment of postpartum hemorrhage (PPH), the 2018 uterotonic recommendations (which included heat-stable carbetocin (HSC) for the prevention of PPH) and their inclusion in the WHO Essential Medicines List (EML), both drugs are still underused or not used at all to manage PPH in many countries with a high burden. HSC is currently being registered in low- and middle-income countries and its policy inclusion is limited and slow. TXA (also heat stable) is available in many countries but is not registered for PPH treatment, which may have contributed to the delay in its inclusion in national guidelines and EMLs. For both drugs, national guidelines will need to be revised and updated for their optimal uptake. We implemented an advocacy initiative to accelerate the necessary normative policy change to ensure access to quality-assured and heat-stable medicines for the prevention and treatment of PPH in Sub-Saharan African countries. Our initiative aimed to raise awareness of the importance of recently recommended medicines for the prevention and treatment of PPH and support the process to update PPH guidelines and EMLs to include these drugs. We highlight the lessons learned during the initiative, including the challenges and opportunities identified in updating PPH policies at the national level.

Causes of Maternal Mortality in Rwanda, 2017-2019.

OBJECTIVE: To assess the causes of maternal mortality at a referral hospital in Rwanda. METHODS: A secondary data analysis of 217 women with recorded maternal mortality from 2017 to 2019 was conducted among 11,308 total maternal admissions. Demographics, diagnosis, management, referring hospital source, and outcomes were recorded. RESULTS: The mean (±SD) age of maternal death was 30.7±7.2 years (range 16-57 years). The overall maternal mortality rate was 1.99%, with yearly rates of 2.45%, 2.53%, and 1.84% in 2017, 2018, and 2019, respectively. A significant seasonal variation was noted. Sepsis was the most common cause of maternal death (50%), followed by hemorrhage (19%) and hypertensive disorders (15%). Causes of maternal deaths included preeclampsia (13%) and abortion (8%). Furthermore, 82% of all the deaths were referrals from smaller community hospitals. CONCLUSION: Maternal death due to sepsis remain a major cause of maternal deaths in Rwanda. Infection prevention and the early diagnosis and management of sepsis must be a priority in reducing maternal mortality.

Prehospital emergency obstetric and neonatal care train-the-trainers program in Rwanda.

OBJECTIVE: To improve maternal mortality rates, our collaboration developed and implemented a context-specific, prehospital Emergency Obstetrics and Neonatal Course (EONC) and train-the-trainers program in Rwanda. METHODS: Two cohorts of staff participated in the program-the SAMU emergency medical service and staff from district hospitals. A 2-day course was developed, consisting of skills stations, simulations, and didactics. A 50-question assessment was administered to both cohorts before and after the courses. Student's t test and matched paired t tests were used to evaluate the assessments through retrospective analysis of the data. RESULTS: EONC1 median scores were 60% versus 92% (pre vs post), using matched-pair analysis of 20 participants. EONC2 median scores were 52% versus 96% (pre vs post), using matched-pair analysis of participants. A one-way analysis of variance mean square analysis showed that regardless of the baseline level of training for each participant, all trainees reached similar post-course assessment scores (F(1)  = 8.35, P = 0.0059). CONCLUSION: Optimal prehospital management of obstetric emergencies is essential to prevent needless mortality and morbidity. This study demonstrated that a context-appropriate prehospital obstetric and neonatal training program could be effectively developed and implemented for the SAMU team in Kigali, Rwanda.

Cancer Control at the District Hospital Level in Sub-Saharan Africa: An Educational and Resource Needs Assessment of General Practitioners.

PURPOSE: The WHO framework for early cancer diagnosis highlights the need to improve health care capacity among primary care providers. In Rwanda, general practitioners (GPs) at district hospitals (DHs) play key roles in diagnosing, initiating management, and referring suspected patients with cancer. We sought to ascertain educational and resource needs of GPs to provide a blueprint that can inform future early cancer diagnosis capacity-building efforts. METHODS: We administered a cross-sectional survey study to GPs practicing in 42 Rwandan DHs to assess gaps in cancer-focused knowledge, skills, and resources, as well as delays in the referral process. Responses were aggregated and descriptive analysis was performed to identify trends. RESULTS: Survey response rate was 76% (73 of 96 GPs). Most responders were 25 to 29 years of age (n = 64 [88%]) and 100% had been practicing between 3 and 12 months. Significant gaps in cancer knowledge and physical exam skills were identified-88% of respondents were comfortable performing breast exams, but less than 10 (15%) GPs reported confidence in performing pelvic exams. The main educational resource requested by responders (n = 59 [81%]) was algorithms to guide clinical decision-making. Gaps in resource availability were identified, with only 39% of responders reporting breast ultrasound availability and 5.8% reporting core needle biopsy availability in DHs. Radiology and pathology resources were limited, with 52 (71%) reporting no availability of pathology services at the DH level. CONCLUSION: The current study reveals significant basic oncologic educational and resource gaps in Rwanda, such as physical examination skills and diagnostic tools. Capacity building for GPs in low- and middle-income countries should be a core component of national cancer control plans to improve accurate and timely diagnosis of cancer. Continuing professional development activities should address and focus on context-specific educational gaps, resource availability, and referral practice guidelines.

Increased Rwandan Access to Obstetrician-Gynecologists Through a U.S.-Rwanda Academic Training Partnership.

OBJECTIVE: To evaluate the first 5 years of the Human Resources for Health Rwanda program from the program onset in the July 2012-2016 academic years, and its effects on access to care through examination of: 1) the number of trained obstetrician-gynecologists (ob-gyns) who graduated from the University of Rwanda and the University of Rwanda-Human Resources for Health program and 2) a geospatial analysis of pregnant women's access to Rwandan public hospitals with trained ob-gyns. METHODS: We used GPS coordinates in this cross-sectional study to identify public (government) hospitals with ob-gyns in 2011 (before initiation of the program) compared with 2016 (year 5 of the program). We compared access to care for the years 2011 and 2016 through geocoding the proportion of pregnant women within 10 and 25 km from these hospitals and compared the travel time to these hospitals in the two time periods. We used a World Pop dataset of Rwandan pregnancies from 2015, ArcGIS for spatial operations, R for statistical analysis, zonal statistics for circular distances, and friction surface for travel time analysis. RESULTS: The number of ob-gyns in public hospitals increased from 14 to 49 nationally. Before the program, 18 residents graduated over a 7-year period (two residents per year); 33 graduated by year 5 (six residents per year). Rwandan faculty increased by 45%. In 2011, most providers were in the capital city. Between 2011 and 2016, the proportion of pregnant women living 10 km from an ob-gyn-staffed public hospital increased from 13.0% to 31.6%; within 25 km increased from 28.4% to 82.9%. Travel time analysis from 2011 to 2016 showed 49.1% of Rwandan women within 1 hour of a hospital and 85.6% within 2 hours. In 2016, this coverage increased to 87.5% and 98.3%, respectively. CONCLUSION: In 5 years, the Human Resources for Health Rwanda program improved the number of residency graduates in obstetrics and gynecology and nationwide access to these providers. The program reduced rural-urban disparities in access to ob-gyns.

Gastric Rupture in Pregnancy: Case Series from a Tertiary Institution in Rwanda and Review of the Literature.

Background Gastric rupture is a rare, life-threatening condition during pregnancy. Case study We present three cases of gastric perforation during pregnancy and the puerperium. The first patient presented with gastric perforation 4 days following an uncomplicated cesarean delivery for obstetric indications. She initially complained of epigastric pain; however, those symptoms resolved. She later demonstrated worsening abdominal distension, intra-abdominal free fluid, and signs of peritonitis. At laparotomy, an ascariasis-associated gastric rupture was diagnosed. She died from sepsis 4 days following the laparotomy. The second patient presented 19 days following a normal vaginal delivery. She presented with hemodynamic instability and underwent emergent laparotomy due to suspected septic shock peritonitis. Gastric rupture was diagnosed intraoperatively. She improved clinically and was discharged home. The third patient underwent emergency cesarean delivery due to non-reassuring fetal status in the setting of preeclampsia. She was initially diagnosed with ascites and pulmonary edema as a result of preeclampsia. Later in her course, she developed features in favor of acute abdomen and signs of sepsis. At the time of emergent laparotomy, a gastric rupture was identified and repaired. She died 2 days later from sepsis. Conclusion We report the management and outcome of three cases of pregnancy-related gastric rupture. To our knowledge, these three cases represent the largest series of pregnancy-related gastric ruptures from a single institution.
