Background Low- and Middle-income countries (LMIC) face considerable health and nutrition challenges, many of which can be addressed through strong academic leadership and robust research translated into evidence-based practice. A North-South-South partnership between three universities was established to implement a master’s programme in nutritional epidemiology at the Kinshasa School of Public Health (KSPH), Democratic Republic of Congo (DRC). The partnership aimed to develop academic leadership and research capacity in the field of nutrition in the DRC. In this article we describe the educational approach and processes used, and discuss successes, challenges, and lessons learned. Methods Self-administered questionnaires, which included both open and closed questions, were sent to all graduates and students on the master’s programme to explore students’ experiences and perceptions of all aspects of the educational programme. Quantitative data was analysed using frequencies, and a thematic approach was used to analyse responses to open-ended questions. Results A two-year master’s programme in Nutritional Epidemiology was established in 2014, and 40 students had graduated by 2020. Key elements included using principles of authentic learning, deployment of students for an internship at a rural residential research site, and support of selected students with bursaries. Academic staff from all partner universities participated in teaching and research supervision. The curriculum and teaching approach were well received by most students, although a number of challenges were identified. Most students reported benefits from the rural internship experience but were challenged by the isolation of the rural site, and felt unsupported by their supervisors, undermining students’ experiences and potentially the quality of the research. Financial barriers were also reported as challenges by students, even among those who received bursaries. Conclusion The partnership was successful in establishing a Master Programme in Nutritional Epidemiology increasing the number of nutrition researchers in the DRC. This approach could be used in other LMIC settings to address health and nutrition challenges.

The average time required to detect an Ebola virus disease (EVD) outbreak following spillover of Ebola virus (EBOV) to a primary human case has remained essentially unchanged for over 40 years, with some of the longest delays in detection occurring in recent decades. In this review, our aim was to examine the relationship between delays in detection of EVD and the duration and size of outbreaks, and we report that longer delays are associated with longer and larger EVD outbreaks. Historically, EVD outbreaks have typically been comprised of less than 100 cases (median = 60) and have lasted less than 4 months (median = 118 days). The ongoing outbreak in Democratic Republic of the Congo, together with the 2013–2016 west Africa outbreak, are stark outliers amidst these trends and had two of the longest delays in detection on record. While significant progress has been made in the development of EVD countermeasures, implementation during EVD outbreaks is problematic. Thus, EVD surveillance must be improved by the broad deployment of modern diagnostic tools, as prompt recognition of EVD has the potential to stem early transmission and ultimately limit the duration and size of outbreaks.

Buruli ulcer is a neglected tropical disease caused by Myocobacterium ulcerans; it manifests as a skin lesion, nodule, or ulcer that can be extensive and disabling. To assess the global burden and the progress on disease control, we analyzed epidemiologic data reported by countries to the World Health Organization during 2010–2017. During this period, 23,206 cases of Buruli ulcer were reported. Globally, cases declined to 2,217 in 2017, but local epidemics seem to arise, such as in Australia and Liberia. In 2013, the World Health Organization formulated 4 programmatic targets for Buruli ulcer that addressed PCR confirmation, occurrence of category III (extensive) lesions and ulcerative lesions, and movement limitation caused by the disease. In 2014, only the movement limitation goal was met, and in 2019, none are met, on a global average. Our findings support discussion on future Buruli ulcer policy and post-2020 programmatic targets.

Background Cryptococcal meningitis is mainly caused by Cryptococcus neoformans/C. gattii complex. We compared the clinical, biological, and antifungal susceptibility profiles of isolates from HIV-Infected Patients (HIVIP) with C. neoformans (Cn) versus C. curvatus/C. laurentii (Cc/Cl) meningitis. Methods Comparative analytical study were conducted. Apart from patients’ clinical data, the following analysis were performed and the results were compared in both groups: biochemical examination, cryptococcal antigen test, India ink staining, and culture on Cerebral Spinal Fluid (CSF), strains identification by mass spectrometry, ITS sequencing, PCR serotyping and antifungal susceptibility. The main outcome variable was the “species of Cryptococcus identified”, which was compared to other variables of the same type using the Pearson Chi-square test or the Fisher exact test. Results A total of 23 (79.3%) Cn meningitis cases versus 6 (20.7%) Cc/Cl meningitis were retained.Cn meningitis was more frequently associated with headache (100% vs 50%, p = 0.005) than Cc/Cl meningitis and meningeal signs were more frequent in Cn infected patients. Biologically, hypoglycorrhachia and low CD4 count were more observed in Cn group (90% vs 20% of patients, p = 0.01; 45.6 vs 129.8 cells/µL, p = 0.02, respectively). A higher proportion of Cn strains (91.3%) showed a low Minimum Inhibitory Concentration (MIC) (Cc/Cl strains (66.7%). Also, Cc/Cl strains resistant to 5-flucytosine and amphotericin B were found in 16.7% of cases for each of the two antifungal agents. Cryptococcus detection by routine analysis (India ink, culture, and antigens) was better for Cn samples than Cc/Cl. Except ITS sequencing, which identified all strains of both groups, mass spectrometry and serotyping PCR identified Cn strains better than Cc/Cl (100% vs 80%, p = 0.1; 100% vs 0%, p Conclusions Clinical presentation of Cn meningitis is certainly more severe than that of Cc/Cl meningitis, but Cc/Cl infection should be considered in the management of HIVIP with meningeal syndrome because of the diagnostic difficulty and the high MICs of antifungal agents required for the treatment of meningitis due to these cryptococcal species.

Background In conflict-affected settings, data on reproductive, maternal, newborn and child health (RMNCH) are often lacking for priority setting and timely decision-making. We aimed to describe the levels and trends in RMNCH indicators within Kivu provinces between 2015 and 2018, by linking conflict data with health facility (HF) data from the District Health Information System 2 (DHIS2). Methods We used data from the DHIS2 for the period 2015–2018, the 2014 Demographic and Health Survey, the 2018 Multiple Indicators Cluster Survey and the Uppsala Conflict Data Program. Health zones were categorised in low, moderate and high conflict intensity level, based on an annual conflict death rate. We additionally defined a monthly conflict death rate and a conflict event-days rate as measures of conflict intensity and insecurity. Outcomes were completion of four antenatal care visits, health facility deliveries, caesarean sections and pentavalent vaccine coverage. We assessed data quality and analyzed coverage and trends in RMNCH indicators graphically, by conflict categories and using HF data aggregated annually. We used a series of fixed-effect regression models to examine the potential dose-response effect of varying conflict intensity and insecurity on RMNCH. Results The overall HF reporting was good, ranging between 83.3 and 93.2% and tending to be lower in health zones with high conflict intensity in 2016 and 2017 before converging in 2018. Despite the increasing number of conflict-affected health zones over time, more in North-Kivu than in South-Kivu, we could not identify any clear pattern of variation in RMNCH coverage both by conflict intensity and insecurity. North-Kivu province had consistently reported better RMNCH indicators than South-Kivu, despite being more affected by conflict. The Kivu as a whole recorded higher coverage than the national level. Coverage of RMNCH services calculated from HF data was consistent with population-based surveys, despite year-to-year fluctuation among health zones and across conflict-intensity categories. Conclusions Although good in general, the HF reporting rate in the Kivu was negatively impacted by conflict intensity especially at the beginning of the DHIS2’s rolling-up. Routine HF data appeared useful for assessing and monitoring trends in RMNCH service coverage, including in areas with high-intensity conflict.

The aim of this review was to summarise the available HBM data in DRC in order to provide recommendations for developing the HBM field. We performed a systematic search of PubMed/MedLine, EMBASE, and ISI Web of Science for papers on exposure levels to chemicals in DR C (2009-2019). A total of 12 papers were found: 9 in Kinshasa (75.0%) and 3 in Katanga (25.0%). Globally, the results reveal concern about exposure levels to environmental chemicals, mostly heavy metals. Some studies connected HBM data to negative health effects (preeclampsia, birth defects, children's temperament difficulties, holoprosencephaly) demonstrating the importance of regulation in occupational and environmental settings. The recommendations of this review include expanding HBM studies as well as the number of environmental chemicals; and establishment of a national HBM laboratory for developing and/or enhancing the capacity of DRC to undertake a national policy-related HBM.

Résumé Contexte Selon les résultats de l’Enquête Démographique et de Santé 2013–2014, la mortalité maternelle et néonatale reste encore élevée en République Démocratique du Congo (RDC). L’objectif de cette étude était d’évaluer la disponibilité, la qualité et l’équité des soins obstétricaux d’urgence (SOU) en RDC. Méthodes En 2014, une enquête transversale était organisée dans 11 provinces de la RDC sur un échantillon de 1 568 formations sanitaires (FOSA) sélectionnées par échantillonnage aléatoire à plusieurs degrés. Les données étaient collectées à travers les interviews, la revue documentaire et l’observation directe. Les informations collectées ont porté sur la disponibilité, la qualité et l’équité des SOU en fonction de la localisation de la FOSA (urbaine ou rurale), son appartenance administrative (publique ou privée), le type de FOSA et la province. Les associations entre les variables étaient mesurées par le test du chi carré de Pearson, au seuil de signification alpha de 0,05. Résultats Au total, 1 555 FOSA (99,2%) étaient enquêtées. Parmi celles-ci, 9,1% fournissaient les SOU de base et 2,9% les SOU complets. L’offre des SOU était inégalement répartie à travers les provinces et selon la localisation de la FOSA, le milieu urbain étant plus favorisé. Les provinces de Kinshasa et du Nord-Kivu étaient mieux servies par rapport aux autres provinces. La césarienne et la transfusion sanguine étaient aussi fournis par les centres de santé (6,5% et 9,0% respectivement) et par les postes de santé (2,3% et 2,3% respectivement) et ce, malgré que les normes d’organisation des zones de santé ne le permet pas. Aucune FOSA ne fournissait les SOU de qualité, suite à l’indisponibilité des normes et directives appropriées. Conclusions La distribution et la qualité des SOU sont encore problématiques. La faible réglementation et la faible supervision des FOSA semble en être un des facteurs contributifs. Nous recommandons au ministère de la santé d’aller au-delà du simple octroi de fonds et d’assurer la mise en place et le suivi des procédures et standards appropriés pour la prestation de service.

Background Inadequate infrastructure, security threats from ongoing armed conflict, and conservative socio-cultural and gender norms that favour large families and patriarchal power structures contribute to poor sexual and reproductive health (SRH) outcomes in North and South Kivu provinces, Democratic Republic of the Congo (DRC). In order to expand contraceptive and post-abortion care (PAC) access in North and South Kivu, CARE, the International Rescue Committee and Save the Children provided technical support to the Ministry of Health and health facilities in these regions. Partners acknowledged that community leaders, given their power to influence local customs, could play a critical role as agents of change in addressing inequitable gender norms, stigma surrounding SRH service utilization, and topics traditionally considered taboo within Congolese society. As such, partners actively engaged with community leaders through a variety of activities such as community mapping exercises, values clarification and transformation (VCAT) activities, situational analyses, and education. Methods This manuscript presents findings from 12 key informant interviews (KIIs) with male political and non-political community leaders conducted in six rural health zones of North and South Kivu, DRC. Transcripts were analysed thematically to explore community leaders’ perceptions of their role in addressing the issue of unintended pregnancy in their communities. Results While community leaders in this study expressed overall positive impressions of contraception and strong support for ensuring access to PAC services following spontaneous and induced abortions, the vast majority held negative beliefs concerning women who had induced abortion. Contrasting with their professed opposition to induced abortion, leaders’ commitment to mediating interpersonal conflict arising between community members and women who had abortions was overwhelming. Conclusion Results from this study suggest that when thoughtfully engaged by health interventions, community leaders can be empowered to become advocates for SRH. While study participants were strong supporters of contraception and PAC, they expressed negative perceptions of induced abortion. Given the hypothesized link between the presence of induced abortion stigma and care-avoidance behavior, further engagement and values clarification exercises with leaders must be integrated into community mobilization and engagement activities in order to increase PAC utilization.

Background Poor awareness of obstetric danger signs is a major contributing factor to delays in seeking obstetric care and hence to high maternal mortality and morbidity worldwide. We conducted the current study to assess the level of agreement on receipt of counseling on obstetric danger signs between direct observations of antenatal care (ANC) consultation and women’s recall in the exit interview. We also identified factors associated with pregnant women’s awareness of obstetric danger signs during pregnancy in the Democratic Republic of Congo (DRC) Methods We used data from the 2017–2018 DRC Service Provision Assessment survey. Agreement between the observation and woman’s recall was measured using Cohen’s kappa statistic and percent agreement. Multivariable Zero-Inflated Poisson (ZIP) regression was used to identify factors associated with the number of danger signs during pregnancy the woman knew. Results On average, women were aware of 1.5 ± 1.34 danger signs in pregnancy (range: 0 to 8). Agreement between observation and woman’s recall was 70.7%, with a positive agreement of 16.9% at the country level but ranging from 2.1% in Bandundu to 39.7% in Sud Kivu. Using multivariable ZIP analysis, the number of obstetric danger signs the women mentioned was significantly higher in multigravida women (Adj.IRR = 1.38; 95% CI: 1.23–1.55), in women attending a private facility (Adj.IRR = 1.15; 95% CI: 1.01–1.31), in women attending a subsequent ANC visit (Adj.IRR = 1.11; 95% CI: 1.01–1.21), and in women counseled on danger signs during the ANC visit (Adj.IRR = 1.19; 95% CI: 1.05–1.35). There was a regional variation in the awareness of danger signs, with the least mentioned signs in the middle and the most in the eastern provinces. Conclusions Our findings indicated poor agreement between directly observed counseling and women’s reports that counseling on obstetric danger signs occurred during the current ANC visit. We found that province of residence, provision of counseling on obstetric danger signs, facility ownership, gravidity and the number of ANC visits were predictors of the awareness of obstetric danger signs among pregnant women. These factors should be considered when developing strategies aim at improving women’s awareness about obstetric danger signs in the DRC

Intimate Partners’ Violence (IPV) is a public health problem with long-lasting mental and physical health consequences for victims and their families. As evidence has been increasing that COVID-19 lockdown measures may exacerbate IPV, our study sought to describe the magnitude of IPV in women and identify associated determinants. An online survey was conducted in the Democratic Republic of Congo (DRC) from 24 August to 8 September 2020. Of the 4160 respondents, 2002 eligible women were included in the data analysis. Their mean age was 36.3 (SD: 8.2). Most women (65.8%) were younger than 40 years old. Prevalence of any form of IPV was 11.7%. Being in the 30–39 and &gt, 50 years’ age groups (OR = 0.66, CI: 0.46–0.95, p = 0.026 and OR = 0.23, CI: 0.11–048, p &lt, 0.001, respectively), living in urban setting (OR = 0.63, CI: 0.41–0.99, p = 0.047), and belonging to the middle socioeconomic class (OR = 0.48, CI: 0.29–0.79, p = 0.003) significantly decreased the odds for experiencing IPV. Lower socioeconomic status (OR = 1.84, CI: 1.04–3.24, p = 0.035) and being pregnant (OR = 1.63, CI: 1.16–2.29, p = 0.005) or uncertain of pregnancy status (OR = 2.01, CI: 1.17–3.44, p = 0.011) significantly increased the odds for reporting IPV. Additional qualitative research is needed to identify the underlying reasons and mechanisms of IPV in order to develop and implement prevention interventions.

The 10th and largest Ebola virus disease epidemic in the Democratic Republic of the Congo (DRC) was declared in North Kivu Province in August 2018 and ended in June 2020. We describe and evaluate an Early Warning, Alert and Response System (EWARS) implemented in the Beni health zone of DRC during August 5, 2018-June 30, 2020. During this period, 194,768 alerts were received, of which 30,728 (15.8%) were validated as suspected cases. From these, 801 confirmed and 3 probable cases were detected. EWARS showed an overall good performance: sensitivity and specificity >80%, nearly all (97%) of alerts investigated within 2 hours of notification, and good demographic representativeness. The average cost of the system was US $438/case detected and US $1.8/alert received. The system was stable, despite occasional disruptions caused by political insecurity. Our results demonstrate that EWARS was a cost-effective component of the Ebola surveillance strategy in this setting.

Background To reduce the malaria burden and improve the socioeconomic status of its citizens, the Democratic Republic of Congo scaled up key malaria control interventions, especially insecticide-treated nets (ITNs), between 2005 and 2014. Since then, the effects of these interventions on malaria mortality and morbidity have not been assessed. This study aimed to measure the impact of the National Malaria Control Programme’s efforts and to inform future control strategies. Methods The authors used data from the Demographic and Health Surveys 2007 and 2013–2014 to assess trends in all-cause childhood mortality (ACCM) against trends in coverage of malaria interventions at national and subnational levels. The authors used the plausibility argument to assess the impact of the malaria control interventions and used Kaplan–Meier survival probability and Cox proportional hazard models to examine the effect of ITN ownership on child survival. Contextual factor trends affecting child survival were also considered. Results Countrywide, household ownership of at least one ITN increased, from 9% in 2007 to 70% in 2013–2014. All provinces experienced similar increases, with some greater than the national level. ITN use increased between 2007 and 2013–2014 among children under five (6% to 55%). Severe anaemia (haemoglobin concentration Conclusions Given the patterns of the coverage of malaria control interventions, patterns in ACCM by province, and marginal improvements in contextual factors, the authors conclude that the malaria control interventions have plausibly contributed to the decrease in ACCM in the Democratic Republic of Congo from 2005 to 2014.

Background Predictions have been made that Africa would be the most vulnerable continent to the novel Coronavirus disease 2019 (COVID-19). Interestingly, the spread of the disease in Africa seems to have been delayed and initially slower than in many parts of the world. Here we report on two cases of respiratory distress in our region before the official declaration of the disease in December 2019, cases which in the present times would be suspect of COVID-19. Case presentation These two cases (one 55-year-old man and one 25-year-old woman) of acute respiratory distress secondary to atypical pneumonia were seen in Bukavu, in Eastern Democratic Republic of the Congo (DRC), between September and December 2019. One patient had returned from China and the other had close contacts with travellers from China in the 2 weeks prior to the onset of symptoms. In either case, the aetiology could not be accurately determined. However, the two cases presented a clinical picture (progressive dyspnoea, preceded by dry cough and fever) and laboratory changes (procalcitonin within the normal range, slight inflammation, and lymphopenia) compatible with a viral infection. The chest X-ray series of the first patient showed lesions (reticulations, ground glass, and nodules ≤6 mm) similar to those currently found in COVID-19 patients. In addition, unlike the 25-year-old female patient who had no comorbidity, the 55-year-old male patient who had hypertension as comorbidity, developed a more severe acute respiratory distress which progressed to death. Conclusion These cases bring to the attention the fact that COVID-19-like syndromes may have already been present in the region months before the official beginning of the pandemic. This also brings to question whether a prior presence of the disease or infections with related virus may account for the delayed and less extensive development of the pandemic in the region.

According to the World Health Organization reports, tuberculosis (TB) remains one of the top 10 deadly diseases of recent decades in the world. In this paper, we present the modeling, analysis and simulation of a mathematical model of TB transmission in a population incorporating several factors and study their impact on the disease dynamics. The spread of TB is modeled by eight compartments including different groups, which are too often not taken into account in the projections of tuberculosis incidence. The rigorous mathematical analysis of this model is provided, the basic reproduction number ($\mathcal{R}_{0}$R0) is obtained and used for TB dynamics control. The results obtained show that lost to follow-up and transferred individuals constitute a risk, but less than the cases carrying germs. Rapidly evolving latent/exposed cases are responsible for the incidence increasing in the short and medium term, while slower evolving latent/exposed cases will be responsible for the persistent long-term incidence and maintenance of TB and delay elimination in the population. The numerical simulations of the model show that, with certain parameters, TB will die out or sensibly reduce in the entire Democratic Republic of the Congo (DRC) population. The strategies on which the DRC’s health system is currently based to fight this disease show their weaknesses because the TB situation in the DRC remains endemic. But monitoring contact, detection of latent individuals and their treatment are actions to be taken to reduce the incidence of the disease and thus effectively control it in the population.

Introduction:the control of the mosquito malaria vectors by the National Malaria Control Programme of the Democratic Republic of Congo (DRC) relies mainly on the use of long-lasting insecticide-treated nets (LLINs). However, the widespread emergence of resistance to pyrethroids is jeopardizing this control strategy. The objective of this study is to determine the status and resistance mechanisms involved inAnopheles gambiae s.l.population of DRC. Methods:pre-imaginal stages ofAn. gambiae s.l.were collected and standard WHO bioassays were performed on adultAn.gambiae s.l.reared in the laboratory from larvae collected from different sites in the study area. The bioassays with the synergist PBO were also performed to determine the likely implication of oxydases in the resistance. The alleles of knock down resistance (Kdr) gene and species of anopheles were determined by PCR-RLFP. Results:all Anopheles mosquitoes tested belonged to the Anopheles gambiae complex.An. gambiae(69.6%) was predominant, followed byAn. coluzzii(25.6%) and (4.8%) hybrids (An. gambiae/ An. coluzzii). Bioassays showed phenotypic resistance to the main insecticides used in the region, notably pyrethroids (deltamethrin, permethrin) and organochlorine (DDT). Only bendiocarb caused 100% mortality. Metabolic resistance involving oxidase enzymes was also detected using the synergist PBO after exposure to deltamethrin. The L1014F allele frequency ofKdrgene was detected in samples collected from all sites at varying frequencies (0.61-1.0). Conclusion:this study brings additional information on malaria vectors resistance to insecticides. It has shown cross-resistance to DDT and pyrethroids as well as the presence ofKdrgene. PBO significantly improved the effectiveness of deltamethrin. The results of this study can be helpful to policy makers in decision making for vector control programmes in the region.

Background Rifampicin (RIF) resistance is highly correlated with isoniazid (INH) resistance and used as proxy for multidrug-resistant tuberculosis (MDR-TB). Using MTBDRplus as a comparator, we evaluated the predictive value of Xpert MTB/RIF (Xpert)–detected RIF resistance for MDR-TB in eastern Democratic Republic of the Congo (DRC). Methods We conducted a cross-sectional study involving data from new or retreatment pulmonary adult TB cases evaluated between July 2013 and December 2016. Separate, paired sputa for smear microscopy and MTBDRplus were collected. Xpert testing was performed subject to the availability of Xpert cartridges on sample remnants after microscopy. Results Among 353 patients, 193 (54.7%) were previously treated and 224 (63.5%) were MTBDRplus TB positive. Of the 224, 43 (19.2%) were RIF monoresistant, 11 (4.9%) were INH monoresistant, 53 (23.7%) had MDR-TB, and 117 (52.2%) were RIF and INH susceptible. Overall, among the 96 samples detected by MTBDRplus as RIF resistant, 53 (55.2%) had MDR-TB. Xpert testing was performed in 179 (50.7%) specimens; among these, 163 (91.1%) were TB positive and 73 (44.8%) RIF resistant. Only 45/73 (61.6%) Xpert-identified RIF-resistant isolates had concomitant MTBDRplus-detected INH resistance. Xpert had a sensitivity of 100.0% (95% CI, 92.1–100.0) for detecting RIF resistance but a positive-predictive value of only 61.6% (95% CI, 49.5–72.8) for MDR-TB. The most frequent mutations associated with RIF and INH resistance were S531L and S315T1, respectively. Conclusions In this high-risk MDR-TB study population, Xpert had low positive-predictive value for the presence of MDR-TB. Comprehensive resistance testing for both INH and RIF should be performed in this setting.

Background Anecdotal reports from DRC suggest that long-lasting insecticidal nets (LLIN) distributed through mass campaigns in DRC may not last the expected average three years. To provide the National Malaria Control Programme with evidence on physical and insecticidal durability of nets distributed during the 2016 mass campaign, two brands of LLIN, DawaPlus® 2.0 and DuraNet©, were monitored in neighbouring and similar health zones in Sud Ubangi and Mongala Provinces. Methods This was a prospective cohort study of representative samples of households from two health zones recruited at baseline, 2 months after the mass campaign. All campaign nets in these households were labelled, and followed up over a period of 31 months. Primary outcome was the “proportion of nets surviving in serviceable condition” based on attrition and integrity measures and the median survival in years. The outcome for insecticidal durability was determined by bio-assay from subsamples of campaign nets. Results A total of 754 campaign nets (109% of target) from 240 households were included in the study. Definite outcomes could be determined for 67% of the cohort nets in Sud Ubangi and 74% in Mongala. After 31 months all-cause attrition was 57% in Sud Ubangi and 76% in Mongala (p = 0.005) and attrition due to wear and tear was 26% in Sud Ubangi and 48% in Mongala (p = 0.0009). Survival in serviceable condition at the last survey was 37% in Sud Ubangi and 17% in Mongala (p = 0.003). Estimated median survival was 1.6 years for the DawaPlus® 2.0 in Mongala (95% CI 1.3–1.9) and 2.2 years for the DuraNet in Sud Ubangi (95% CI 2.0–2.4). Multivariable Cox proportionate hazard models suggest that the difference between sites was mainly attributable to the LLIN brand. Insecticidal effectiveness was optimal for DuraNet©, but significantly dropped after 24 months for DawaPlus® 2.0. Conclusions In the environment of northwest DRC the polyethylene LLIN DuraNet© performed significantly better than the polyester LLIN DawaPlus® 2.0, but both were below a three-year median survival. Improvement of net care behaviours should be able to improve physical durability.

ObjectiveThe early diagnosis of neonatal sepsis remains a challenge for physicians. The initiation or/and discontinuation of the empirical antibiotic therapy at neonates with sepsis is a dilemma due to the lack of definitive diagnosis and the fear of misdiagnosing a case with its serious outcomes, which can follow up. Therefore, this study aimed to assess the usefulness of C-reactive protein (CRP) as an inflammatory biomarker in the prediction of the neonatal sepsis diagnosis in Butembo, the Democratic Republic of the Congo, in sub-Saharan Africa. Blood culture and quantitative CRP measurements were performed for each neonate. Receiver operating characteristics (ROC) analyses were done in the assessment of CRP accuracy in diagnosing neonatal sepsis.ResultsOf the 228 neonates screened for sepsis, 69 (30.3%) had a positive blood culture. Of the 228 neonates with suspected sepsis, 94 (41.2%) had a positive CRP. Among the 69 cases with positive blood culture, CRP identified 66 cases. The sensitivity, specificity, positive and negative predictive values of CRP were 95.7%, 82.4%, 70.2%, and 97.8%, respectively. The area under the curve (AUC) for the CRP ROC analysis was 0.948. CRP showed its usefulness in the diagnosis of neonatal sepsis.

In the Democratic Republic of Congo (DRC), acute kidney injury (AKI) contributes to the high rate of child mortality owing to the conjunction of poverty, deficiency of qualified health-care providers in pediatric nephrology, and the lack of pediatric dialysis programs. We aimed to describe the recent experience of the first pediatric acute peritoneal dialysis (PD) program in DRC. This is a retrospective cohort study on epidemiology, clinical features and outcomes of children admitted from January 2018 to January 2019 at the University Hospital of Kinshasa for AKI and treated with PD. This pediatric PD program started by a team of one physician and one nurse who were trained in the local production of PD fluids and bedside catheter insertion technique in Benin Republic. The training was jointly supported by the Flemish Inter-University Council (VLIR) TEAM project and Saving Young Lives (SYL) program of ISN, ISPD, EuroPD, and IPNA. From January 2018 to January 2019, 49 children (aged 4 months-15 years) were admitted for AKI mainly due to severe malaria and sepsis. Dialysis was indicated in 35 of 49 (71.4%), 32 of 35 (91.4%) were treated with PD, two with hemodialysis (HD) in adult ward and one died at admission. Data of the two patients transferred for HD were not available for follow-up. The main indications were uremia and prolonged anuria. Of 32 dialyzed patients, 24 (75%) recovered normal renal function 3 months after discharge. Peritonitis was observed in 2 of 32 (6.2%) patients and the mortality was 18.7%. This promising experience proves that with simple means including use of locally produced dialysis fluids and low peritonitis rates, we can effectively save lives of children suffering from AKI. ispartof: PERITONEAL DIALYSIS INTERNATIONAL vol:40 issue:5 pages:504-508 ispartof: location:United States status: published

Background The loss of chloroquine (CQ) effectiveness has led to its withdrawal from national policies as a first-line treatment for uncomplicated malaria in several endemic countries, such as the Democratic Republic of Congo (DRC). The K76T mutation on the pfcrt gene has been identified as a marker of CQ resistance and the SVMNT haplotype in codons 72–76 on the same gene has been associated with resistance to amodiaquine (AQ). In the DRC, the prevalence of K76T has decreased from 100% in 2000 to 63.9% in 2014. The purpose of this study was to determine the prevalence of K76T mutations in circulating strains of Plasmodium falciparum, 16 years after CQ withdrawal in the DRC and to investigate the presence of the SVMNT haplotype. Methods In 2017, ten geographical sites across the DRC were selected. Dried blood samples were collected from patients attending health centres. Malaria was first detected by a rapid diagnostic test (RDT) available on site (SD Bioline Malaria Ag Pf or CareStart Malaria Pf) or thick blood smear and then confirmed by a P. falciparum species-specific real-time PCR assay. A pfcrt gene segment containing a fragment that encodes amino acids at positions 72–76 was amplified by conventional PCR before sequencing. Results A total of 1070 patients were enrolled. Of the 806 PCR-confirmed P. falciparum positive samples, 764 were successfully sequenced. The K76T mutation was detected in 218 samples (28.5%; 95% CI 25.4%–31.9%), mainly (96%) with the CVIET haplotype. Prevalence of CQ resistance marker was unequally distributed across the country, ranging from 1.5% in Fungurume to 89.5% in Katana. The SVMNT haplotype, related to AQ resistance, was not detected. Conclusion Overall, the frequency of the P. falciparum CQ resistance marker has decreased significantly and no resistance marker to AQ was detected in the DRC in 2017. However, the between regions variability of CQ resistance remains high in the country. Further studies are needed for continuous monitoring of the CQ resistance level for its prospective re-use in malaria management. The absence of the AQ resistance marker is in line with the use of this drug in the current DRC malaria treatment policy.

Summary: The Democratic Republic of Congo (DRC) (formerly Zaire) was the location of the first Ebola outbreak, in 1976, and since then there have been a total of ten outbreaks in different parts of the country. The current outbreak, the first in eastern DRC (North Kivu and Ituri provinces), began in July 2018, and by December 2019, there had been 3262 cases and 2232 deaths. Within weeks of the first reported cases, the World Health Organisation (WHO) and the DRC Ministry of Health (MOH) initiated a major response programme, with laboratory support, international agencies providing personnel, and material resources. Unlike previous Ebola outbreaks, including the west Africa epidemic, a proven vaccine, and trial therapeutic agents have been available as part of the outbreak response. Two therapeutic agents, mAb114 and REGN-EB3, both monoclonal antibody derived, have shown case fatality rates (CFR) of around 30%, compared to the overall of 66%. Despite these positive interventions, the outbreak has continued for eighteen months. Underlying the outbreak response has been a high number of violent incidents by local militias, and community mistrust and lack of involvement that has hampered many aspects of the response programme. As a result, many cases are not reported early and not transferred to treatment centres, deaths and increased transmission occur in the community, and the response programme is reaching only a proportion of the cases. New strategies to improve community participation, and integrate the Ebola response into the existing health structure are planned to improve the programme effectiveness.

Background Sulfadoxine–pyrimethamine (SP) is a cornerstone of malaria chemoprophylaxis and is considered for programmes in the Democratic Republic of Congo (DRC). However, SP efficacy is threatened by drug resistance, that is conferred by mutations in the dhfr and dhps genes. The World Health Organization has specified that intermittent preventive treatment for infants (IPTi) with SP should be implemented only if the prevalence of the dhps K540E mutation is under 50%. There are limited current data on the prevalence of resistance-conferring mutations available from Eastern DRC. The current study aimed to address this knowledge gap. Methods Dried blood-spot samples were collected from clinically suspected malaria patients [outpatient department (OPD)] and pregnant women attending antenatal care (ANC) in four sites in North and South Kivu, DRC. Quantitative PCR (qPCR) was performed on samples from individuals with positive and with negative rapid diagnostic test (RDT) results. Dhps K450E and A581G and dhfr I164L were assessed by nested PCR followed by allele-specific primer extension and detection by multiplex bead-based assays. Results Across populations, Plasmodium falciparum parasite prevalence was 47.9% (1160/2421) by RDT and 71.7 (1763/2421) by qPCR. Median parasite density measured by qPCR in RDT-negative qPCR-positive samples was very low with a median of 2.3 parasites/µL (IQR 0.5–25.2). Resistance genotyping was successfully performed in RDT-positive samples and RDT-negative/qPCR-positive samples with success rates of 86.2% (937/1086) and 55.5% (361/651), respectively. The presence of dhps K540E was high across sites (50.3–87.9%), with strong evidence for differences between sites (p Dhps A581G mutants were less prevalent (12.7–47.2%). The dhfr I164L mutation was found in one sample. Conclusions The prevalence of the SP resistance marker dhps K540E exceeds 50% in all four study sites in North and South Kivu, DRC. K540E mutations regularly co-occurred with mutations in dhps A581G but not with the dhfr I164L mutation. The current results do not support implementation of IPTi with SP in the study area.

Developmental dyslexia is a reading disorder characterized by problems in accurate or fluent reading. A deficiency in phonological processing is thought to underpin the reading difficulties of individuals with developmental dyslexia and a variety of explanations have been proposed including deficits in phonological awareness and verbal memory. Recent investigations have begun to suggest that developmental deficits in the acquisition of reading may also co-occur with visual processing deficits, which are particularly salient for visually complex stimuli, yet these deficits have received relatively little attention from researchers. To further explore the nature of phonological and visual processing in developmental dyslexia, we administered a series of non-reading tasks tapping both domains. Unsurprisingly, individuals with developmental dyslexia performed worse than typically developing readers in phonological tasks. More intriguingly, they also struggled with visual tasks, specifically when discriminating between novel visual patterns, and in visuo-spatial working memory, which requires greater attentional control. These findings highlight that individuals with developmental dyslexia present not only with phonological impairments but also difficulties in processing visual materials. This aspect has received limited attention in previous literature and represents an aspect of novelty of this study. The dual phonological and visual impairments suggest that developmental dyslexia is a complex disorder characterized by deficits in different cognitive mechanisms that underpin reading.

Despite being important conservation tools, tourism and research may cause transmission of pathogens to wild great apes. Investigating respiratory disease outbreaks in wild bonobos, we identified human respiratory syncytial virus and Streptococcus pneumoniae as causative agents. A One Health approach to disease control should become part of great ape programs.

Background Female survivors of sexual violence in conflict experience not only physical and psychological sequelae from the event itself, but often many negative social outcomes, such as rejection and ostracisation from their families and community. Male relatives – whether husbands, fathers, brothers – play a key role in determining how the family and community respond to a survivor of sexual violence. Understanding these perspectives could help improve services for survivors of sexual violence, as well as their families and communities. Methods This study draws on qualitative data gathered from focus groups of 68 men in the eastern region of Democratic Republic of Congo. Men were asked about their experiences as relatives of women who had experienced sexual violence. Results Two dominant themes arose throughout the focus groups: factors driving rejection and pathways to acceptance. Factors driving rejection included: fear of sexually transmitted infections, social stigma directed toward the husbands themselves, and an understanding of marriage and fidelity that is incompatible with rape. Men also touched on their own trauma, including struggling with witnessing a rape that took place in public, or caring for a survivor with a child from rape. They noted that the economic burden of medical treatment for survivors was a salient factor in the decision to reject. Pathways to acceptance included factors such as the love of their spouse or relative, survivors’ potential to give continued financial contribution to the family, the need to keep the family together to care for children in the home, and pressure from people of importance in the community. Conclusion This study provides unique insight into how male relatives respond to close family members who have experienced sexual violence. This is particularly critical since the reaction of a male relative after rape can be the most pivotal factor in promoting or impeding recovery for a survivor. These results emphasise the importance of services that focus not only on the survivor of violence herself, but also on key family members that can ideally help support her recovery.

Highlights • PPV viruses could be circulating in pig-rearing regions in DRC as they can spread easily by the movement of live animals and pork products. • The presence of PPV viral DNA in pigs without reproductive failure help in understanding the persistence of PPV. • The similarity of PPV3 at nucleotide sequence level suggests that the virus may have a common source., Porcine Parvovirus (PPV) is one of the major pathogens responsible for reproductive failure in sows. However, the information on its frequency in the Democratic Republic of Congo (DRC) is largely unknown. Thus, the present study was carried out to detect and genetically characterize some of known Parvovirus namely porcine parvovirus 1, 2, 3, 4, porcine bocavirus (PBoV) 1, and porcine bocavirus-like virus (PBolikeV) in 80 randomly selected archive pig farm samples during an African swine fever (ASF) survey in South Kivu, eastern DRC by polymerase chain reaction (PCR). The majority of animals analyzed (82.5%) were local breeds, and most of them (87.5%) were adults (above one year old). The majority of the animals (65%) were from the free range farms. The PCR result indicated that only PPV3 was detected in 14/80 pigs. Seven swine herds (8.7%) were co-infected with PPV3 and ASFV. Morever, a significantly high PPV3 infection rate was observed in the spleen (66.7%, P

The global disruptions caused by the coronavirus disease 2019 crisis posed a threat to the momentum the vector control team at the Liverpool School of Tropical Medicine (LSTM) and the Programme National de Lutte contre la Tryaponosomiase Humaine Africaine (PNLTHA) had built in their efforts to control tsetse fly populations in the Democratic Republic of Congo. But despite the pandemic and global lockdown, field activities did continue and the same impressive results in tsetse fly reduction were observed and the team followed this by completing a round of ‘tiny target’ deployment without any external presence. Such a success was possible due to the investment in vector control capacity strengthening undertaken by the LSTM and PNLTHA.

A community-directed treatment with ivermectin (CDTI) for fighting onchocerciasis was started in 2003 in the hyperendemic province of Bandundu, Democratic Republic of Congo (DRC); such initiative was supported by the African Programme for Onchocerciasis Control (APOC). As the APOC stopped at the end of 2015, there was an urgent need to assess the sustainability of an ivermectin treatment. A cross-sectional survey of knowledge, attitude and perception was conducted to determine the awareness level of local population regarding the disease. A multi-stage random sampling technique allowed the selection of 450 heads of households. Most respondents (96.9%) knew about onchocerciasis as a disease. The black-fly was viewed as the causing agent of onchocerciasis by 49.9% of respondents. The most commonly cited clinical manifestations were nodules (34.4%) and pruritus (31.1%), while blindness was the most frequently reported complication (90.7%). Approximately 55.1% of respondents had a good knowledge of onchocerciasis and CDTI. Overall, only 37% of participants had a favourable attitude and 46% a positive perception. Good knowledge was associated with school attendance (adjusted OR=1.9, 95%CI: 1.3-2.8, p=0.001), while education and continuation of treatment were related with good attitude (adjusted OR=9.7, 95%CI:4.8-19.5 and adjusted OR=19.8, 95%CI: 9.7-40.6, respectively, both with p, SCOPUS: ar.j, info:eu-repo/semantics/published

Ethnopharmacological relevance: The main objective of the present study was to collect and gather information on herbal remedies traditionally used for the treatment of malaria in Bukavu and Uvira, two towns of the South Kivu province in DRC. Material and methods: Direct interview with field enquiries allowed collecting ethnobotanical data; for each plant, a specimen was harvested in the presence of the interviewed traditional healers (THs). The recorded information included vernacular names, morphological parts of plants, methods of preparation and administration of remedies, dosage and treatment duration. Plants were identified with the help of botanists in the herbaria of INERA/KIPOPO (DRC) and the Botanic Garden of Meise (Belgium), where voucher specimens have been deposited. The results were analysed and discussed in the context of previous published data. Results: Interviewees cited 45 plant species belonging to 41 genera and 21 families used for the treatment of malaria. These plants are used in the preparation of 52 recipes, including 25 multi-herbal recipes and 27 mono-herbal recipes. Apart of Artemisia annua L. (Asteraceae; % Citation frequency = 34%) and Carica papaya L. (Caricaceae; % Citation frequency = 34%), the study has highlighted that the most represented families are Asteraceae with 12 species (26%), followed by Fabaceae with 7 species (16%) and Rubiaceae with 4 species (9%). For a majority of plants, herbal medicines are prepared from the leaves in the form of decoction and administered by oral route. Conclusion: Literature data indicate that part of cited species are already known (38%) and/or studied (30%) for antimalarial properties, which gives credit to the experience of Bukavu and Uvira interviewees and some level of confidence on collected information. The highly cited plants should be investigated in details for the isolation and identification of active ingredients, a contribution to the discovery of new possibly effective antimalarials., SCOPUS: ar.j, info:eu-repo/semantics/published

Unwanted and mistimed pregnancies impose threats on the health and well-being of the mother and child and limit the acquisition of optimal sexual and reproductive health services, especially in resource-constrained settings like the Democratic Republic of Congo (DRC). This study aimed to determine the prevalence and correlates of mistimed and unwanted pregnancies among women in the DRC. Data were drawn from the 2013–14 DRC Demographic Health Survey (EDS-RDC II). Bivariate and multivariate logistic regression analysis was performed to identify correlates of mistimed and unwanted pregnancies. Sequential logistic regression modelling including distal (place of residence), intermediate (socio-demographic and socioeconomic factors) and proximal (reproductive health and family planning) factors was performed using multivariate analysis. More than a quarter (28%) of pregnancies were reported as unintended (23% mistimed and 5% unwanted). Women who wanted no more children (aOR 1.21; CI: 1.01, 1.44) had less than 24 months of birth spacing (aOR 2.14; CI: 1.80, 2.54) and those who intended to use a family planning method (aOR 1.24; CI: 1.01, 1.52) reported more often that their last pregnancy was mistimed. Women with five or more children (aOR 2.13; CI: 1.30, 3.49), those wanting no more children (aOR 13.07; CI: 9.59, 17.81) and those with more than 48 months of birth spacing (aOR 2.31; CI: 1.26, 4.23) were more likely to report their last pregnancy as unwanted. The high rate of unintended pregnancies in the DRC shows the urgency to act on the fertility behaviour of women. The associated intermediate factors for mistimed and unwanted pregnancy indicate the need to accelerate family planning programmes, particularly for women of high parity and those who want no more children. Likewise, health promotion measures at the grassroots level to ensure women’s empowerment and increase women’s autonomy in health care are necessary to address the social factors associated with mistimed pregnancy.
