Estimating the causal effect of dexamethasone versus hydrocortisone on the neutrophil- lymphocyte ratio in critically ill COVID-19 patients from Tygerberg Hospital ICU using TMLE method.

Background: Causal inference from observational studies is an area of interest to researchers, advancing rapidly over the years and with it, the methods for causal effect estimation. Among them, Targeted Maximum Likelihood estimation (TMLE) possesses arguably the most outstanding statistical properties, and with no outright treatment for COVID-19, there was an opportunity to estimate the causal effect of dexamethasone versus hydrocortisone upon the neutrophil-lymphocyte ratio (NLR), a vital indicator for disease progression among critically ill COVID-19 patients.

Methods: TMLE variations were used in the analysis.

Mobile outreach clinics for improving health care services accessibility in vulnerable populations of the Diffa Region in Niger: a descriptive study.

Background: Niger is a large country with many distant locations that can be difficult to access because the Sahara Desert covers 80% of the country's land. In Niger, just 49% of residents have access to a health centre within 5 km of their house. Health care may be difficult to access in the Diffa region of Niger, as non-state armed groups strike on a regular basis and floods cause a high rate of vulnerability.

Caregivers' hesitancy and outright refusal toward children's COVID-19 vaccination in the Democratic Republic of Congo: A community-based cross-sectional study.

Data from the global South show higher COVID-19-related mortality in children compared to the North. Parents' willingness to vaccinate their children once COVID-19 vaccines are available is poorly documented. We assessed parents' willingness to vaccinate their children in the DRC.

COVID-19 Vaccine Hesitancy and Associated Oral Cholera Vaccine Hesitancy in a Cholera-Endemic Country: A Community-Based Cross-Sectional Study in the Democratic Republic of Congo.

COVID-19 vaccine hesitancy and its enablers shape community uptake of non-covid vaccines such as the oral cholera vaccine (OCV) in the post-COVID-19 era. This study assessed the impact of COVID-19 vaccine hesitancy and its drivers on OCV hesitancy in a cholera-endemic region of the Democratic Republic of Congo. We conducted a community-based survey in Bukavu.

Socio-Demographic Factors Influencing Malaria Vaccine Acceptance for Under-Five Children in a Malaria-Endemic Region: A Community-Based Study in the Democratic Republic of Congo.

Two novel vaccines against malaria are proposed as a complementary control tool to prevent and reduce related disease and death in under-five children from moderate to high malaria transmission regions. The Democratic Republic of Congo (DRC) has committed to eradicate malaria by 2030, and significant efforts have been deployed to strengthen control and elimination measures. We aimed to understand factors influencing the malaria vaccine acceptability among the general population in eastern DRC.

Health transformation toward universal healthcare coverage amidst conflict: examining the impact of international cooperation in Niger.

Background: Approximately 70% of Sub-Saharan African countries have experienced armed conflicts with significant battle-related fatalities in the past two decades. Niger has witnessed a substantial rise in conflict-affected populations in recent years. In response, international cooperation has aimed to support health transformation in Niger's conflict zones and other conflict-affected areas in Sub-Saharan Africa.

Rabies mortality and morbidity associated with animal bites in Africa: a case for integrated rabies disease surveillance, prevention and control: a scoping review.

Objective: The objective of this scoping review was to map the current situation and available evidence and gaps on rabies morbidity, mortality, integrated rabies surveillance programmes, and existing prevention and control strategies in Africa.

Methods: We conducted a systematic scoping review following the Joanna Briggs methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews checklist. Medline, Embase, CINAHL (EBSCOHost), Scopus, Web of Science and rabies web conferences were used to search for peer-reviewed publications between January 1946 and May 2020.

Human immunodeficiency virus-associated tuberculosis care in Botswana: evidence from a real-world setting.

Background: Tuberculosis (TB) is among the world's top public health challenges and the leading killer of people with HIV, yet is a treatable disease. This study aimed to assess, in a real-world setting, the implementation of antiretroviral therapy (ART) and Cotrimoxazole preventive therapy (CPT) policy, specific interventions proven to benefit patients in HIV-associated TB care.

Methods: This retrospective cohort study was conducted in Botswana in the Serowe/Palapye district, a largely urban district with a high burden of HIV-associated TB with a high case fatality, at Segkoma and Palapye hospitals and their feeder clinics.
