Malaria among children under 10 years in 4 endemic health areas in Kisantu Health Zone: epidemiology and transmission.

BACKGROUND: The Democratic Republic of the Congo (DRC) is the second most malaria-affected country in the world with 21,608,681 cases reported in 2019. The Kongo Central (KC) Province has a malaria annual incidence of 163 cases/per 1000 inhabitants which are close to the national average of 153.4/1000. However, the malaria prevalence varies both between and within health zones in this province. The main objective of this study was to describe the epidemiology and transmission of malaria among children aged 0 to 10 years in the 4 highest endemic health areas in Kisantu Health Zone (HZ) of KC in DRC. METHODS: A community-based cross-sectional study was conducted from October to November 2017 using multi-stage sampling. A total of 30 villages in 4 health areas in Kisantu HZ were randomly selected. The prevalence of malaria was measured using a thick blood smear (TBS) and known predictors and associated outcomes were assessed. Data are described and association determinants of malaria infection were analysed. RESULTS: A total of 1790 children between 0 and 10 years were included in 30 villages in 4 health areas of Kisantu HZ. The overall prevalence in the study area according to the TBS was 14.8% (95% CI: 13.8-16.6; range: 0-53). The mean sporozoite rate in the study area was 4.3% (95% CI: 2.6-6.6). The determination of kdr-west resistance alleles showed the presence of both L1014S and L1014F with 14.6% heterozygous L1014S/L1014F, 84.4% homozygous 1014F, and 1% homozygous 1014S. The risk factors associated with malaria infection were ground or wooden floors aOR: 15.8 (95% CI: 8.6-29.2), a moderate or severe underweight: 1.5 (1.1-2.3) and to be overweight: 1.9 (95% CI: 1.3-2.7). CONCLUSION: Malaria prevalence differed between villages and health areas within the same health zone. The control strategy activities must be oriented by the variety in the prevalence and transmission of malaria in different areas. The policy against malaria regarding long-lasting insecticidal nets should be based on the evidence of metabolic resistance.

A North-South-South partnership in higher education to develop health research capacity in the Democratic Republic of the Congo: the challenge of finding a common language.

BACKGROUND: Globally, increasing numbers of higher education institutions (HEIs) in non-English-speaking countries have adopted English as a medium of instruction (EMI), because of the perception that this provides opportunities to attract high-calibre students and academic staff, and engage with the international research community. We report an evaluation of a North-South-South collaboration to develop health research capacity in the Democratic Republic of the Congo (DRC) by establishing a postgraduate programme in nutritional epidemiology at the Kinshasa School of Public Health (KSPH), where EMI was adopted. We report experiences and perceptions of stakeholders, facilitators and students about using EMI. METHODS: In-depth qualitative interviews were conducted between October and December 2019 among convenience sampled stakeholders (8), facilitators (11) and students (12) involved in the programme from all three partner institutions (University of Kinshasa; University of KwaZulu-Natal, South Africa; University of Bergen, Norway). Interviews were conducted in participants' language of preference (English or French), audio-recorded, transcribed verbatim and translated into English when required. Analysis employed a thematic approach. RESULTS: Most participants viewed EMI positively, reporting that studying in English created opportunities to access relevant literature, improve interactions with the scientific community and advance their careers. As a result of adopting EMI, some students had opportunities to present research findings at international conferences and publish their research in English. English-speaking researchers from partner institutions were able to participate in supervision of students' research. However, inadequate English competency, particularly among students, was challenging, with some students reporting being unable to understand or interact in class, which negatively affected their academic performance. Further, EMI created barriers at KSPH among academic staff who were not proficient in English, leading to poor participation among non-English-speaking staff and lack of integration with other postgraduate programmes. Participants suggested additional English language support for EMI. CONCLUSION: Partnerships between HEIs could be a powerful tool to develop research capacity in low-income countries in line with United Nations Sustainable Development Goals. EMI could be a solution to language barriers faced by many such partnerships, but wide-ranging support to develop English proficiency among staff and students is essential to ensure that the challenges do not outweigh the benefits.

Establishing a postgraduate programme in nutritional epidemiology to strengthen resource capacity, academic leadership and research in the democratic republic of Congo.

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.

Population-based prevalence of human T-lymphotropic virus type 1 in sub-Saharan Africa: a systematic review and meta-analysis.

BACKGROUND: Human T-cell lymphotropic virus type 1 (HTLV-1), the causative agent of adult T-cell leukaemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), is endemic in sub-Saharan Africa (SSA) and poses a high morbidity and mortality risk. Its prevalence in the general population is poorly understood. The potential for prevention motivated us to do a systematic review and meta-analysis of population-based studies to estimate the prevalence of HTLV-1 in SSA. METHODS: A comprehensive, no-limit search was conducted in EMBASE, PubMed, Web of Science and the Cochrane Library from their inception dates to March 2019. Population-based studies presenting data on HTLV-1 in sub-Saharan Africa were included. Pooled prevalence was estimated using a random-effects meta-analysis. RESULTS: A total of 21 studies were included, representing 42 297 participants. The pooled HTLV-1 seroprevalence was 3.19% (95% CI 2.36-4.12%) with variations across year of study. Prevalence of HTLV-1 positively correlated with year of study (ß = 0.0036, P = 0.007). Participants from Central, Western and Southern Africa had a seroprevalence of 4.16% (95% CI 2.43-6.31%), 2.66% (95% CI 1.80-3.68%) and 1.56% (95% CI 0.48-3.15%), respectively. CONCLUSIONS: Our findings suggest that HTLV-1 infection is a public health concern in SSA and highlight the need to implement effective preventive programmes and interventions aimed at reducing the burden of this common yet neglected infection.

PRÉVALENCE DANS LA POPULATION DU VIRUS T-LYMPHOTROPIQUE HUMAIN DE TYPE 1 (HTLV-1) EN AFRIQUE SUBSAHARIENNE: OBJECTIF: Le virus lymphotropique T humain 1 (HTLV-1), l'agent causal de la leucémie T de l'adulte/lymphome (ATL) et la myélopathie associée à HTLV-1/paraparésie spastique tropicale (HAM/TSP), est endémique en Afrique subsaharienne (ASS) et présente un risque élevé de morbidité et de mortalité. Sa prévalence dans la population générale est mal comprise. Le potentiel de prévention nous a incité à procéder à une revue systématique et à une méta-analyse des études basées sur la population afin d'estimer la prévalence du HTLV- 1 en ASS. MÉTHODES: Une recherche approfondie et sans limite a été effectuée dans EMBASE, PUBMED, Web of Science et dans la Cochrane Library, depuis leur création jusqu'à mars 2019. Des études basées sur la population présentant des données sur HTLV-1 en ASS ont été incluses. La prévalence poolée a été estimée à l'aide d'une méta-analyse à effet aléatoire. RÉSULTATS: Un total de 21 études ont été incluses, représentant 42.297 participants. La séroprévalence poolée du HTLV-1 était de 3,19% (IC95%: 2,36% à 4,12%), avec des variations au cours de l'année de l'étude. La prévalence du HTLV-1 était corrélée positivement avec l'année d'étude (bêta = 0,0037, p = 0,007). Les participants d'Afrique centrale, de l'Ouest et Australe présentaient une séroprévalence de 4,16% (IC95%: 2,43% à 6,31%), de 2,66% (IC95%: 1,80% à 3,68%) et 1,56% (IC95%: 0,48% à 3,15%), respectivement. CONCLUSIONS: Nos résultats suggèrent que l'infection au HTLV-1 est une préoccupation de santé publique en ASS et soulignent la nécessité de mettre en œuvre des programmes et des interventions préventives efficaces visant à réduire la charge de cette infection commune mais négligée.

Seroprevalence of human T-lymphotropic virus (HTLV) in blood donors in sub-Saharan Africa: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Human T-cell lymphotropic viruses (HTLV) 1 and 2 are endemic in sub-Saharan Africa (SSA), transfusion-transmissible and causally linked to various severe diseases. However, even in SSA countries with moderate to high endemicity, routine blood donor screening for HTLV is rarely, if ever, performed. Information on seroprevalence is limited. The aim of this review is to establish the prevalence of HTLV-1 and HTLV-1/2 among blood donors in sub-Saharan Africa. MATERIALS AND METHODS: We systematically reviewed databases including EMBASE, MEDLINE and the Cochrane database library from their inception to June 2018. Studies presenting data on HTLV prevalence among blood donors in sub-Saharan Africa were included. A random-effect meta-analysis was conducted on all eligible studies. RESULTS: A total of 25 studies were included, representing 74 119 blood donors, of whom over 80% (61 002) were only tested for HTLV-1. The evidence base was high and moderate in quality. The pooled prevalence of the 17 studies that screened only for HTLV-1 and the nine studies that screened for HTLV-1/2 was 0·68 (95% CI: 0·29-1·60) and 1·11 (95% CI: 0·47-2·59) per 100 blood donors, respectively. CONCLUSION: The prevalence of HTLV-1 infection among blood donors is relatively low. The current review is intended to inform debates and decisions about best practices to prevent transfusion-transmitted HTLV in sub-Saharan Africa. Further work is required to determine the risk of infections by transfusion and the cost-effectiveness of any new measures such as routine screening.

Prevalence and determinants of use of complementary and alternative medicine by hypertensive patients attending primary health care facilities in Kinshasa, Democratic Republic of the Congo: a cross-sectional study.

BACKGROUND: In the Democratic Republic of the Congo the control of hypertension is poor, characterized by an increasing number of reported cases of hypertension related complications. Poor control of hypertension is associated with non-adherence to antihypertensive medication. It is well established that the use of complementary and alternative medicine is one of the main factors of non-adherence to antihypertensive medication. The aim of this study is to determine the prevalence and factors associated with the use of complementary and alternative medicine. METHODS: A cross-sectional study was carried out at the Kinshasa Primary Health-care (KPHC) facilities network in November 2014. A structured interview questionnaire was administrated to a total of 280hypertensive patients. Complementary and alternative medicine were defined according to the National Institute of Health classification as a group of diverse medical and healthcare systems, practices, and products that are not presently considered to be part of conventional medicine. Data were summarized using proportion and mean (with standard deviation). The student's t test and χ2 test were used respectively for mean and proportion comparison. Logistic regression analysis identified determinants of the use of complementary and alternative medicine. RESULTS: The prevalence of use of complementary and alternative medicine was 26.1% (95% CI: 20.7% - 31.8%).Determinants of use of complementary and alternative medicine included misperception about hypertension curability (OR = 2.1; 95%CI: 1.1-3.7) and experience of medication side effects (OR = 2.9; 95%CI: 1.7-5.1). CONCLUSION: The use of CAM for hypertensive patients is a major problem; antihypertensives with fewer side effects must be emphasized. Religious leaders must become involved in the communication for behavioral change activities to improve the quality of life for hypertensive patients.

Red blood cell alloimmunization in transfused patients in sub-Saharan Africa: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: Previous studies of Sub-Saharan Africans show significant alloimmunization to red blood cell (RBC) antigens, but country-specific data are limited. Thus, the aim of this study was to estimate, by meta-analysis, the overall proportion of red blood cell alloantibodies among transfused patients. METHODS: We systematically searched Medline, Embase, and the Africa-Wide Information database to identify relevant studies in any language. Case reports, comments, letters, conference abstracts, editorials, and review articles were excluded. Of the 269 potentially relevant articles, 11 studies fulfilled our selection criteria. RESULTS: Overall proportions of alloimmunization were 6.7 (95% CI: 5.7, 7.8) per 100 transfused patients. With regard to antibody specificity, among clinically significant antibodies, anti-E ranked as the most common, followed by anti-K, anti-C and anti-D. CONCLUSION: Meta-analysis of available literature quantifies and qualifies the clinical challenge of RBC alloimmunization among transfused patients in Sub-Saharan Africa. These results should drive policy decisions in favour of routine testing of RBC antigens and irregular antibodies for transfused patients as a standard of care throughout Sub-Saharan Africa.

Assessment of hypertension management in primary health care settings in Kinshasa, Democratic Republic of Congo.

BACKGROUND: Hypertension-related complications have become more diagnosed at secondary and tertiary care levels, in the Democratic Republic of the Congo (DRC), probably indicative of poor management of hypertensive patients at primary health care level. This study aimed to assess the management of hypertension in primary health care settings by using guidelines of the International Forum for Prevention and Control of HTN in Africa (IFHA). METHODS: A multi-center cross-sectional study was carried out in primary health care settings. A total of 102 nurses were surveyed using a structured interview. Mean and proportion comparisons were performed using the t Student test and the Chi-square test respectively. The Kinshasa Primary Health Care network facilities were compared with non-Kinshasa Primary Health Care network facilities. RESULTS: From the 102 nurses surveyed; 52.9% were female with a mean age of 41.1, (SD = 10) years, merely 9.5% benefited from in-job training on cardiovascular diseases or their risk factors, and 51.7% had guidelines on the management of hypertension. Less than a quarter of the nurses knew the cut-off values of hypertension, diabetes and obesity. Merely 14.7% knew the therapeutic goals for uncomplicated hypertension. Several of the indicators for immediate referral recommended by IFHA were unmentioned. The content of patient education was lacking, avoiding stress being the best advice provided to hypertensive patients. The antihypertensive most used were unlikely to be recommended by the IFHA. CONCLUSIONS: This study showed a considerable gap of knowledge and practices in the management of hypertensive patients at primary health care facilities in Kinshasa pertaining to the IFHA guidelines. We think that task-shifting for management of hypertension is feasible if appropriate guidelines are provided and nurses trained.

Assessment of health service delivery capacities, health providers' knowledge and practices related to type 2 diabetes care in Kinshasa primary healthcare network facilities, Democratic Republic of the Congo.

BACKGROUND: Democratic Republic of the Congo (DRC) is experiencing an increase in the morbi-mortality related to Non Communicable Diseases (NCD). The reform of DRC health system, based on Health District model, is needed in order to tackle this public issue. This article used 2006 International Diabetes Federation (IDF)'s guidelines to assess the capacities of health facilities belonging to Kinshasa Primary Health Care Network (KPHCN) in terms of equipments, as well as the knowledge, and the practice of their health providers related to type 2 diabetes care. METHODS: A multicentric cross-sectional study was carried in 18 Health Facilities (HF) of KPHCN in charge of the follow-up of diabetic patients. The presence of IDF recommended materials and equipment was checked and 28 health providers were interviewed about their theoretical knowledge about patients' management and therapeutic objectives during recommended visits. Chi square test or Fisher exact test was used to compare proportions and the Student t-test to compare means. RESULTS: The integration of NCD healthcare in the KPHC network is feasible. The majority of HF possessed IDF recommended materials except for the clinical practice guidelines, urinary test strips, and monofilament, available in only one, two and four HF, respectively. KPHCN referral facilities had required materials for biochemical analyses, the ECG and for the fundus oculi test. Patients' management is characterized by a lack of attention on the impairment of renal function during the first visits and a poor respect of recommended practices during quarterly and annual visits. A poor knowledge of the reduction of cardiovascular risk factors-related therapeutic objectives has been also reported. CONCLUSION: The capacities, knowledge, and practice of T2D care were poor among HF of KPHCN. The lack of equipment and training of healthcare professionals should be supplied even to those who are not medical doctors. Special attention must to be put on the clinical practice guidelines formulation and sensitization and on supervision.

MC4R rs17782313 gene polymorphism was associated with glycated hemoglobin independently of its effect on BMI in Japanese: the Shimane COHRE study.

BACKGROUND: Type 2 diabetes (T2D) is among the leading public health problems in Japan, and glycated hemoglobin (HbA1c) can be used to screen the population for T2D. Gene polymorphisms, known to be associated with obesity, may predispose individuals to T2D. Rs17782313 the melanocortin 4 receptor (MC4R) has shown one of the strongest associations with body mass index (BMI). We conducted a study to investigate whether rs17782313 (TT versus TC + CC) was associated with HbA1c. METHOD: We conducted a cross-sectional study including 1142 Japanese adults (446 men: 64.9 ± 14.4 years and 696 women: 66.7 ± 12.3 years). MC4R rs17782313 was genotyped using fast real-time polymerase chain reaction. RESULTS: TC + CC genotype group showed significantly greater BMI (p = 0.039) and HbA1c (p = 0.001) than TT genotype group after adjustment for gender, age and, for HbA1c, BMI. Further analysis using linear regression analysis confirmed that the effect of MC4R rs17782313 on HbA1c (ß = 0.08; p = 0.003) was independent of the effect age, gender, BMI, low density lipoprotein cholesterol, homeostasis model assessment of insulin resistance and of beta cell function. This significant independent association was similarly noticed in non-obese (ß = 2.82; p = 0.005) subgroups. CONCLUSION: MC4R rs17782313 was associated with obesity and could confer a certain susceptibility to T2D that could be independent of its pro-obesity effect.

When knowledge is not enough: barriers to recommended cassava processing in resource-constrained Kwango, Democratic Republic of Congo.

Background: Despite interventions to provide knowledge and improve bitter cassava processing in the Democratic Republic of Congo (DRC), cassava processing is sub-optimal. Consumption of insufficiently processed bitter cassava is associated with konzo, a neurological paralytic disease. Objective: This study aimed to explore barriers to appropriate cassava processing carried out by women in one deep rural, economically deprived area of DRC. Methods: A qualitative design used focus group discussions (FGDs) and participant observation to collect data among purposively selected women aged 15-61 years in Kwango, DRC. Data were analyzed using thematic analysis. Results: 15 FGDs with 131 women and 12 observations of cassava processing were undertaken. Observations indicated women did not follow recommended cassava processing methods. Although women were knowledgeable about cassava processing, two main barriers emerged: access to water and lack of money. Accessing water from the river to process cassava was burdensome, and the cassava was at risk of being stolen by soaking it in the river; therefore, women shortened the processing time. Cassava was not only used as a staple food but also as a cash crop, which led to households shortening the processing time to reach the market quickly. Conclusion: Knowledge about the risks of insufficient cassava processing and about safe processing methods alone is insufficient to change practices in a context of severe resource constraints. When planning nutrition interventions, it is critical to view the intervention in light of the socio-economic context in which the intervention will take place to improve its outcomes.

Determinants of uncontrolled allergic rhinitis in Kinshasa hospitals.

Objective: To identify the determinants of uncontrolled allergic rhinitis (UCAR) in a hospital setting in Kinshasa, Democratic Republic of Congo. Methods: Hospital-based cross-sectional study of 153 patients with allergic rhinitis (AR). The diagnosis of AR was based on clinical grounds according to the Allergic Rhinitis and its Impact on Asthma (ARIA) criteria. Categorization into controlled AR (CAR) and UCAR was based on the visual analog scale (VAS with cut off point of 5). Binary logistic regression was used to identify factors associated with UCAR. Results: Patients with UCAR (60.1%) proportionally outnumbered those with CAR (39.9%). There were significantly more patients younger than 30 years of age among patients with UCAR. Factors significantly associated with UCAR were age below 30 years (OR = 3.31; 95% CI: 1.49-7.36; p = 0.003), low serum vitamin D level (OR = 3.86; 95% CI: 1.72-8.68; p = 0.001), persistent form (OR = 3.11; 95% CI: 1.39-6.98; p = 0.006) and moderate to severe form of AR (OR = 4.31; 95% CI: 1.77-10.49; p = 0.001). Conclusions: Factors associated with UCAR in this study population were younger age less than 30 years, low vitamin D level, and persistent as well as moderate to severe AR. Further studies are needed to elucidate the underlying mechanisms favoring the occurrence of these factors.

Is stunting in children under five associated with the state of vegetation in the Democratic Republic of the Congo? Secondary analysis of Demographic Health Survey data and the satellite-derived leaf area index.

Background: The prevalence of stunting in the Democratic Republic of the Congo (DRC) is one of the highest globally. However, only a few studies have attempted to measure the association between stunting and vegetation, which is an important food source. The leaf area index (LAI) is an excellent measure for the vegetation state. Objective: This paper intended to measure the association between the LAI and stunting among children under five years of age in the DRC. Its aim was to better understand the boundary conditions of stunting and explore potential links to climate and environmental change. Methods: This paper adopts a secondary data analysis approach. We used data on 5241 children from the DRC Demographic Health Survey (DHS) 2013-2014, which was collected from a nationally representative cross-sectional survey. We used the satellite-derived LAI as a measure for the state of vegetation and created a 10-km buffer to extract each DHS cluster centroid's corresponding mean leaf-area value. We used a generalised mixed-effect logistic regression to measure the association between LAI and stunting, adjusting the model for mother's education, occupation and birth interval, as well as child's age and national wealth quintile. A height-for-age Z-score (HAZ) was calculated and classified according to WHO guidelines. Results: Children in communities surrounded by high LAI values have lower odds of being stunted (OR [odds ratio] = 0.63; 95% CI [confidence interval] = 0.47-0.86) than those exposed to low LAI values. The association still holds when the exposure is analysed as a continuous variable (OR = 0.84; 95% CI = 0.74-0.95).When stratified in rural and urban areas, a significant association was only observed in rural areas (OR = 0.6; 95% CI = 0.39-0.81), but not in urban areas (OR = 0.9; 95% CI = 0.5-0.5). Furthermore, the study showed that these associations were robust to LAI buffer variations under 25 km. Conclusions: Good vegetation conditions have a protective effect against stunting in children under five years of age. Further advanced study designs are needed to confirm these findings.

'I am not only beneficial to the community but to the entire country, I am trained as a researcher now': Developing health research skills in low-income countries.

ABSTRACTPartnerships between Higher Education Institutions in the global South and North have potential for building capacity in public health research in low-resource countries. We present experiences of partners involved in a North-South-South partnership between universities in Norway, the Democratic Republic of Congo (DRC) and South Africa. The partnership aimed to establish a postgraduate programme in nutritional epidemiology at the University of Kinshasa, DRC, and develop a cadre of researchers and academic leaders to provide locally generated health research to inform policy. In-depth interviews were conducted with 31 purposively selected stakeholders, facilitators, and students from partner institutions. All participants expressed positive experiences, indicating that the partnership provided excellent opportunities to network, enriched participants' learning and enhanced academic growth, with benefits at individual, institutional, and country levels. Participants suggested that maintaining a common vision was important for success, facilitated by joint planning of project activities, focussing strongly on building research and academic capacity at Kinshasa School of Public Health and addressing local nutrition problems. Important challenges highlighted for future partnerships included failures of co-facilitation and co-supervision, poor research dissemination and policy impact, and concerns about sustainability. Notwithstanding, North-South-South partnerships can address skills shortages in public health research with significant benefits to all partner institutions.

Evidence of Community-Wide Spread of Multi-Drug Resistant Escherichia coli in Young Children in Lusaka and Ndola Districts, Zambia.

Increased antimicrobial resistance (AMR) has been reported for pathogenic and commensal Escherichia coli (E. coli), hampering the treatment, and increasing the burden of infectious diarrhoeal diseases in children in developing countries. This study focused on exploring the occurrence, patterns, and possible drivers of AMR E. coli isolated from children under-five years in Zambia. A hospital-based cross-sectional study was conducted in the Lusaka and Ndola districts. Rectal swabs were collected from 565 and 455 diarrhoeic and healthy children, respectively, from which 1020 E. coli were cultured and subjected to antibiotic susceptibility testing. Nearly all E. coli (96.9%) were resistant to at least one antimicrobial agent tested. Further, 700 isolates were Multi-Drug Resistant, 136 were possibly Extensively-Drug Resistant and nine were Pan-Drug-Resistant. Forty percent of the isolates were imipenem-resistant, mostly from healthy children. A questionnaire survey documented a complex pattern of associations between and within the subgroups of the levels of MDR and socio-demographic characteristics, antibiotic stewardship, and guardians' knowledge of AMR. This study has revealed the severity of AMR in children and the need for a community-specific-risk-based approach to implementing measures to curb the problem.

Prevalence and determinants of hypertension among students of the University of Kinshasa, Democratic Republic of Congo: a cross-sectional study.

BACKGROUND: The 2017 ACC/AHA Guideline categorized blood pressure into 4 levels:normal (SBP<120 and DBP <80mm Hg), elevated (SBP of 120-129 or DBP< 80 mmHg) and stage 1 (SBP of 130-139 or DBP of 80-89 mm Hg) or 2 (SBP≥140 orDBP≥90mmHg). Compared with the JNC7 guideline, the 2017 ACC/AHA guideline recommends using lower SBP and DBP levels to define hypertension. OBJECTIVE: To determine the prevalence of hypertension as well as associated factors among students of the University of Kinshasa. METHODS: This was a cross-sectional study conducted at the University of Kinshasa and including 1 281 students aged between 18 and 30. Blood pressure was assessed according to the WHO STEPwise approach, which is a standardized method of data collection, analysis and dissemination for the surveillance of non-communicable diseases in WHO member countries. The Chi-square and Student's t-tests and a multivariate logistic regression analysis have been used to evaluate the results. Statistical analyses were done using IBM SPSS version 21. RESULTS: The prevalence of hypertension according to the guidelines from the 2017 ACC/AHA and the JNC 7 was 26.4 % (CI 95%; 23.9 - 28.9) and 7.3 % (CI 95%; 5.8 - 8.8), respectively. The results of multivariate logistic regression analysis showed that smoking, alcohol abuse, overweight, male sex, age ≥ 24 years old and low physical activity were associated with hypertension (p < 0.0001). CONCLUSION: At least one out of four students had hypertension. These data should encourage public health authorities to develop strategies for screening of BP and topromote the adoption of healthy lifestyle in young adults.

Prevalence and Molecular Epidemiology of Human T-Lymphotropic Virus Type 1 among Women Attending Antenatal Clinics in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Human T-cell lymphotropic virus type 1 (HTLV-1) imposes a substantial disease burden in sub-Saharan Africa (SSA), which is arguably the world's largest endemic area for HTLV-1. Evidence that mother-to-child transmission persists as a major mode of transmission in SSA prompted us to estimate the pooled prevalence of HTLV-1 among pregnant women throughout the region. We systematically reviewed databases including EMBASE, MEDLINE, Web of Science, and the Cochrane Database of Systemic Reviews from their inception to November 2018. We selected studies with data on HTLV-1 prevalence among pregnant women in SSA. A random effect meta-analysis was conducted on all eligible data and heterogeneity was assessed through subgroup analyses. A total of 18 studies, covering 14,079 pregnant women, were selected. The evidence base was high to moderate in quality. The pooled prevalence, per 100 women, of the 18 studies that screened HTLV-1 was 1.67 (95% CI: 1.00-2.50), a figure that masks regional variations. In Western, Central, Southern, and Eastern Africa, the numbers were 2.34 (1.68-3.09), 2.00 (0.75-3.79), 0.30 (0.10-0.57), and 0.00 (0.00-0.21), respectively. The prevalence of HTLV-1 infection among pregnant women in SSA, especially in Western and Central Africa, strengthens the case for action to implement routine screening of pregnant women for HTLV-1. Rigorous studies using confirmatory testing and molecular analysis would characterize more accurately the prevalence of this infection, consolidate the evidence base, and further guide beneficial interventions.

Disclosure of HIV status and its impact on the loss in the follow-up of HIV-infected patients on potent anti-retroviral therapy programs in a (post-) conflict setting: A retrospective cohort study from Goma, Democratic Republic of Congo.

BACKGROUND: The study aimed to identify the impact of non-disclosure of HIV status on the loss to follow-up (LTFU) of patients receiving anti-retroviral therapy. METHODOLOGY: A historic cohort of HIV patients from 2 major hospitals in Goma, Democratic Republic of Congo was followed from 2004 to 2012. LTFU was defined as not taking an ART refill for a period of 3 months or longer since the last attendance, and had not yet been classified as 'dead' or 'transferred-out'. Kaplan-Meier plots were used to determine the probability of LTFU as a function of time as inclusive of the cohort. The log-rank test was used to compare survival curves based on determinants. Cox proportional hazard modeling was used to measure predictors of LTFU from the time of treatment induction until December 15th, 2012 (the end-point). RESULTS: The median follow-up time was 3.99 years (IQR = 2.33 to 5.59). Seventy percent of patients had shared their HIV status with others (95% CI: 66.3-73.1). The proportion of LTFU was 12% (95%CI: 9.6-14.4). Patients who did not share their HIV status (Adjusted HR 2.28, 95% CI 1.46-2.29), patients who did not live in the city of Goma (Adjusted HR 1.97, 95% CI 1.02-3.77), and those who attained secondary or higher education level (Adjusted HR 1.60, 95% CI 1.02-2.53) had a higher hazard of being LTFU. CONCLUSION: This study shows the relationship between the non-disclosure HIV status and LTFU. Healthcare workers in similar settings should pay more attention to clients who have not disclosed their HIV status, and to those living far from health settings where they receive medication.

Investigating the remuneration of health workers in the DR Congo: implications for the health workforce and the health system in a fragile setting.

The financial remuneration of health workers (HWs) is a key concern to address human resources for health challenges. In low-income settings, the exploration of the sources of income available to HWs, their determinants and the livelihoods strategies that those remunerations entail are essential to gain a better understanding of the motivation of the workers and the effects on their performance and on service provision. This is even more relevant in a setting such as the DR Congo, characterized by the inability of the state to provide public services via a well-supported and financed public workforce. Based on a quantitative survey of 1771 HWs in four provinces of the DR Congo, this article looks at the level and the relative importance of each revenue. It finds that Congolese HWs earn their living from a variety of sources and enact different strategies for their financial survival. The main income is represented by the share of user fees for those employed in facilities, and per diems and top-ups from external agencies for those in Health Zone Management Teams (in both cases, with the exception of doctors), while governmental allowances are less relevant. The determinants at individual and facility level of the total income are also modelled, revealing that the distribution of most revenues systematically favours those working in already favourable conditions (urban facilities, administrative positions and positions of authority within facilities). This may impact negatively on the motivation and performance of HWs and on their distribution patters. Finally, our analysis highlights that, as health financing and health workforce reforms modify the livelihood opportunities of HWs, their design and implementation go beyond technical aspects and are unavoidably political. A better consideration of these issues is necessary to propose contextually grounded and politically savvy approaches to reform in the DR Congo.

The misuse of Cyproheptadine: a non-communicable disease risk behaviour in Kinshasa population, Democratic Republic of Congo.

BACKGROUND: Obesity is one of the main risk factors of non-communicable diseases (NCDs) worldwide, especially in sub-Saharan Africa. The use of Cyproheptadine increases body weight and the risk of becoming obese. The aim of this study is to determine the prevalence of Cyproheptadine misuse in the Kinshasa population and to describe its characteristics. METHODS: A cross-sectional study was conducted in two town sectors of Kinshasa, Democratic Republic of Congo (DRC), over a 4 month period (May 2011 to August 2011). Data from 499 participants, aged between 13 and 55 years were collected and analyzed. Mean and standard deviation were used for quantitative variables and frequency and percentage for categorical variables. In order to determine the relationship between socio-demographic status and Cyproheptadine use the Chi-square test was conducted. Student's t-test was used to compare means age of Cyproheptadine users and non-users. Logistic regression was used to determine predictors of Cyproheptadine use. A p-value of <0.05 was considered statistically significant. RESULTS: Overall, 499 participants were enrolled (352 females, 147 males, mean age ± standard deviation 24.9 ± 9.7 years) in the study. The majority of the study participants (72.9 %) had used Cyproheptadine as an appetite stimulant. Females were 11 times more likely to use Cryproheptadine (OR = 11.9; 95 % CI: 7.1-20.1) than males. People aged between 36 and 55 were three times less likely to use Cryproheptadine (OR = 0.3; 95 % CI: 0.2-0.8) compared to teenagers. More than half of the participants (69.0 %) declared to take daily Cyproheptadine. Half of the study participants (50.0 %) used Cyproheptadine for more than a year and also declared to combine it with Dexamethasone (87.6 %). CONCLUSION: This study shows that the Kinshasa population is significantly misusing Cyproheptadine and is highly exposed to its risk, including obesity.
