The environmental drivers of bacterial meningitis epidemics in the Democratic Republic of Congo, central Africa.

Introduction: Bacterial meningitis still constitutes an important threat in Africa. In the meningitis belt, a clear seasonal pattern in the incidence of meningococcal disease during the dry season has been previously correlated with several environmental parameters like dust and sand particles as well as the Harmattan winds. In parallel, the evidence of seasonality in meningitis dynamics and its environmental variables remain poorly studied outside the meningitis belt.

Impact of patron saint festivities on cholera in three communes in Haiti.

Background: Religious pilgrimages are among the anthropogenic factors known to be associated with the transmission of diarrheal diseases, such as cholera. This ecological study aimed to describe the evolution of cholera and assess the relationship between the implementation of the 'coup de poing' strategy during the patron saint festivities and the incidence of cholera in the three communes of Cabaret, Carrefour, and Croix-des-Bouquets in Haiti in 2017.

Methods: An epidemiological curve was produced to illustrate the evolution of cholera at the communal level.

[Maternal affectivity during pregnancy, mother-child relationship, infant´s health and development in Kinshasa].

Introduction: the impact of prenatal maternal affectivity on infant development is poorly documented in Africa. The purpose of our study is to determine the relationship between mother feelings about pregnancy and childbirth, infant´s behavior and development.

Methods: one hundred and twenty mothers aged 28,4 years (± 12,18 years) with their babies aged 38,70 months (± 19,19) were enrolled in a cross-sectional study based on an interview and questionnaire on maternal affectivity, mother-child relationship, infant´s behavior and psychosocial development.

Travel burden and clinical presentation of retinoblastoma: analysis of 1024 patients from 43 African countries and 518 patients from 40 European countries.

Background: The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.

Methods: A cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries.

A dashboard for monitoring preventive measures in response to COVID-19 outbreak in the Democratic Republic of Congo.

Background: In most health areas, an information system is necessary for an effective fight against COVID-19. Current methods for surveillance of diseases with epidemic potential do not include monitoring the adherence to preventive measures. Furthermore, modern data collection methods depend often on technologies (e.

Diagnostic dilemma in postpartum associated hemolytic uremic syndrome in a 38th week pregnant 31-year-old Congolese: a case report.

Background: Thrombotic microangiopathy is associated with HELLP syndrome, thrombotic thrombocytopenic purpura, or atypical hemolytic uremic syndrome (aHUS) during pregnancy. Standard laboratory and physical examinations can help distinguish between these three diseases promptly and guide their management. This is critical because their managements and prognoses differ considerably.

Probability of Major Depression Classification Based on the SCID, CIDI, and MINI Diagnostic Interviews: A Synthesis of Three Individual Participant Data Meta-Analyses.

Introduction: Three previous individual participant data meta-analyses (IPDMAs) reported that, compared to the Structured Clinical Interview for the DSM (SCID), alternative reference standards, primarily the Composite International Diagnostic Interview (CIDI) and the Mini International Neuropsychiatric Interview (MINI), tended to misclassify major depression status, when controlling for depression symptom severity. However, there was an important lack of precision in the results.

Objective: To compare the odds of the major depression classification based on the SCID, CIDI, and MINI.

Prevalence and Risk Factors of CKD in South Kivu, Democratic Republic of Congo: A Large-Scale Population Study.

Background: The prevalence of chronic kidney disease (CKD) in African American individuals is high but whether this applies to native populations in sub-Saharan Africa is unclear.

Methods: In a cross-sectional study, we assessed the prevalence and risk factors of CKD in rural and urban adults in South Kivu, Democratic Republic of Congo. Glomerular filtration rate (GFR) was estimated using the CKD-Epidemiology Collaboration (CKD-EPI) equations based on serum creatinine (eGFRcr), cystatin C (eGFRcys), or both markers (eGFRcr-cys), without ethnic correction factor.

[Second ear piercing for aesthetic purposes and appearance of pathological scars in negroids: About 172 observations in an endemic area of keloids].

This is a transverse and retrospective descriptive study carried out on a quantitative and qualitative component on pathological scars after a second ear piercing for aesthetic purposes in a Negroid female population from an endemic area of keloids. For a period of 10 years (from January 1, 2010 to December 31, 2019), we observed 172 patients with pathological ear scars after a second piercing for aesthetic purposes including 65.7% of female students and 22.

Impact of a free care policy on the utilisation of health services during an Ebola outbreak in the Democratic Republic of Congo: an interrupted time-series analysis.

Background: During past outbreaks of Ebola virus disease (EVD) and other infectious diseases, health service utilisation declined among the general public, delaying health seeking behaviour and affecting population health. From May to July 2018, the Democratic Republic of Congo experienced an outbreak of EVD in Equateur province. The Ministry of Public Health introduced a free care policy (FCP) in both affected and neighbouring health zones.

Targeted next-generation sequencing of sputum for diagnosis of drug-resistant TB: results of a national survey in Democratic Republic of the Congo.

The surveillance of drug resistance among tuberculosis (TB) patients is central to preventing the spread of antimicrobial resistance. The Democratic Republic of the Congo (DR Congo) is classified by the World Health Organization (WHO) as a country with a high burden of TB and multidrug-resistant TB (MDR-TB), but there are no nationally representative data on drug resistance. In 2016-2017, a national survey of TB patients was conducted in 108 microscopy centres across all 11 provinces of the country using innovative molecular approaches.

Comparing the durability of the long-lasting insecticidal nets DawaPlus 2.0 and DuraNet© in northwest Democratic Republic of Congo.

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.

[Medical laboratories and quality of care: the most neglected components of rural hospitals in the Democratic Republic of the Congo].

Introduction: Quality of care is essential to save people living with different diseases. However, inappropriate diagnosis may in no case lead to proper patient management as well as to quality of care. We conducted a cross-sectional descriptive analysis in three laboratories at the General Hospitals in the Democratic Republic of the Congo.

Understanding the spatio-temporal dynamics of meningitis epidemics outside the belt: the case of the Democratic Republic of Congo (DRC).

Background: Bacterial meningitis remains a major threat for the population of the meningitis belt. Between 2004 and 2009, in the countries of this belt, more than 200,000 people were infected with a 10% mortality rate. However, for almost 20 years, important meningitis epidemics are also reported outside this belt.

[Care providers' knowledge and willingness to prescribe pre-exposure prophylaxis (PrEP) in Kinshasa, Democratic Republic of Congo (DRC)].

Introduction: reducing the incidence of new HIV infections is a public health goal. The purpose of this study was to evaluate the knowledge and willingness to prescribe PrEP in Kinshasa.

Methods: we conducted a cross-sectional analytical study among care providers of 4 health facilities where HIV treatment was offered in the city of Kinshasa from April to October 2017.

Global Retinoblastoma Presentation and Analysis by National Income Level.

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale.

Adaptation of the Sniffin' Sticks Test in South-Kivu.

Aim: The "Sniffin' Sticks" test is widely used in Europe as a standard test to assess olfaction. Several culturally-adapted versions have been developed. However, no version adapted to Sub-Saharan African populations exists.

Environmental and anthropogenic factors associated with increased malaria incidence in South-Kivu Province, Democratic Republic of the Congo.

Objective: To examine environmental and human factors that affect the spatial and temporal dynamism of malaria in DRC's South-Kivu province.

Methods: In a cross-sectional study conducted between 1 January 2010 and 31 December 2015, spatial distribution was determined through thematic maps of malaria attack rate. SatScan ™ software and Monte Carlo test were used to identify spatial risk clusters.

Ent-abietane and ent-pimarane diterpenoids from Croton mubango (Euphorbiaceae).
