Seroprevalence is expressed as a range according to different cut-off calculations. Between 6.

The feasibility of implementing Toronto childhood cancer stage guidelines and estimating the impact on outcome for childhood cancers in seven pediatric oncology units in sub-Saharan Africa. A study from the Franco-African Pediatric Oncology Group.

Background: The improvement of childhood cancer outcome is determined by early diagnosis, effective treatment, supportive care, and adequate medical follow-up. Stage at diagnosis may reflect timeliness of diagnosis, therefore standardized registration of stage is essential for interpretation of regional differences and time trends in survival. Here, we describe the feasibility of implementing the Toronto Childhood Cancer Stage Guidelines (hereafter Toronto Guidelines [TG]) in the hospital-based cancer registry of the Franco-African Pediatric Oncology Group (GFAOP), and assess the impact of TG stage on outcome in pediatric oncology units (POUs) in seven low- and middle-income countries in sub-Saharan Africa (SSA).

[Interventional study on Dolutegravir and other antiretrovirals in patients with subclinical atherosclerosis in the Kinshasa Hospital].

Introduction: After 2016, the World Health Organization (WHO) proposed Dolutegravir (DTG) as an alternative first-line treatment for adults. Thus, the purpose of this study was to identify biomarkers of cardiometabolic risk capable of demonstrating the beneficial effect of Dolutegravir (DTG) compared to other antiretrovirals in predicting atherosclerosis in people living with HIV (PLHIV) and hospitalized in Kinshasa Hospital.

Methods: we conducted an interventional study of people living with HIV who had received antiretroviral therapy (ART) for at least 6 months and were treated in the structures of the network coordinated by the Catholic Church (BDOM-Bureau Diocésain des Oeuvres Médicales) and of the University Clinics of Kinshasa (CUK) between January 2017 and December 2021.

Use of Mpox Multiplex Serology in the Identification of Cases and Outbreak Investigations in the Democratic Republic of the Congo (DRC).

Human Mpox cases are increasingly reported in Africa, with the highest burden in the Democratic Republic of Congo (DRC). While case reporting on a clinical basis can overestimate infection rates, laboratory confirmation by PCR can underestimate them, especially on suboptimal samples like blood, commonly used in DRC. Here we used a Luminex-based assay to evaluate whether antibody testing can be complementary to confirm cases and to identify human transmission chains during outbreak investigations.

Transcranial doppler velocities in a large healthy population of African children.

Background And Purpose: Transcranial doppler ultrasound (TCD) is a tool that diagnoses and monitors pathophysiological changes to the cerebrovasculature. As cerebral blood flow velocities (CBFVs) increase throughout childhood, interpretation of TCD examinations in pediatrics requires comparison to age matched normative data. Large cohorts of healthy children have not been examined to develop these reference values in any population.

Head-to-head comparison of diagnostic accuracy of four Ebola virus disease rapid diagnostic tests versus GeneXpert® in eastern Democratic Republic of the Congo outbreaks: a prospective observational study.

Background: Ebola virus disease (EVD) outbreaks have emerged in Central and West Africa. EVD diagnosis relies principally on RT-PCR testing with GeneXpert®, which has logistical and cost restrictions at the peripheral level of the health system. Rapid diagnostic tests (RDTs) would offer a valuable alternative at the point-of-care to reduce the turn-around time, if they show good performance characteristics.

SARS-CoV2 mutations and impact on mortality: observational study in a sub-saharan Africa hospital.

Background: One year after the coronavirus disease 2019 (COVID-19) pandemic, the focus of attention has shifted to the emergence and spread of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants of concern (VOCs). The aim of the study was to assess the frequency of VOCs in patients followed for COVID-19 at Kinshasa university hospital (KUH) during the 3rd and 4th waves of the pandemic in Kinshasa. Hospital mortality was compared to that of the first two waves.

Coronaviruses Are Abundant and Genetically Diverse in West and Central African Bats, including Viruses Closely Related to Human Coronaviruses.

Co-occurrence of oculocutaneous albinism type 2 and mild sickle cell disease explained by HbS/βthal genotype in an individual from the Democratic Republic of Congo.

Oculocutaneous albinism type 2 (OCA2) is a pigmentation disorder characterized by hypopigmentation of the skin, hair and eyes and ocular features. Sickle cell disease (SCD) is caused either by homozygosity of the beta globin gene variant c.20A > T/p.

Are Any Changes in Carotid Intima-Media Thickness Associated with Cardiometabolic Risk Among Adult Bantu Central African Hypertensive Patients from Monkole and Biamba Marie Mutombo Hospitals?

Background: Several classic/traditional risk factors are associated with intima-media thickness (IMT), a novel risk of cardio metabolic risk (CMR) in the literature but not in Kinshasa, a megacity prone to CMR. Thus, the objective of this study was to evaluate potential correlations between inflammation, kidney function, psychological stress, hemodynamics, and changes in IMT.

Methods: This cross-sectional study was carried out between 2018 and 2021 within Monkole and Biamba Marie Mutombo Hospitals, respectively, and randomly selected from 10 health structures from East and West of Kinshasa, Capital of Democratic Republic Congo (DRC).

Seroprevalence of IgG Antibodies Against Multiple Arboviruses in Bats from Cameroon, Guinea, and the Democratic Republic of Congo.

Emergence of mosquito-borne arboviruses has caused significant public health burden. The life cycle of arboviruses comprises sylvatic and urban cycles, including a wildlife reservoir, a human host, and an arthropod vector. However, many questions remain on the sylvatic cycles of arboviruses.

Field performance of three Ebola rapid diagnostic tests used during the 2018-20 outbreak in the eastern Democratic Republic of the Congo: a retrospective, multicentre observational study.

Background: The Democratic Republic of the Congo has confronted 13 outbreaks of Ebola virus disease since 1976. Rapid diagnostic tests (RDTs) detecting viral antigens have been developed to circumvent difficulties encountered with RT-PCR for diagnosis in remote low-resource settings, but there is still uncertainty about their performance characteristics and usability during outbreaks. We aimed to assess the field performance of three antigen detection RDTs compared with the gold-standard Cepheid GeneXpert Ebola assay results.

Prevalence and incidence of arterial hypertension and its risk factors in the 7,525 person-years Congolese adult population between 2012 and 2019 : results of the Bukavu observational study.

Herpes Infections in Suspected Cases of Yellow Fever in the Democratic Republic of the Congo.

In the battle to quickly identify potential yellow fever arbovirus outbreaks in the Democratic Republic of the Congo, active syndromic surveillance of acute febrile jaundice patients across the country is a powerful tool. However, patients who test negative for yellow fever virus infection are too often left without a diagnosis. By retroactively screening samples for other potential viral infections, we can both try to find sources of patient disease and gain information on how commonly they may occur and co-occur.
