Les moustiquaires imprégnées d´insecticides à longue durée d´action (MILDA) sont nécessaires dans la lutte anti vectorielle du paludisme. Cependant, leur distribution n´est pas encore optimale en région sub-saharienne. Selon les projections, la pandémie de COVID-19 retarderait davantage la distribution des MILDA. Au Niger, une campagne de distribution des MILDA avec une approche multi-sectorielle (Etat-partenaire -société civile) a été organisée dans le respect de mesure barrières contre la COVID-19. La stratégie porte-à-porte dans les ménages a été retenue pour l´organisation de cette campagne pour éviter les espaces clos et garder l´aspect communautaire. Un total de 13.994.681 personnes a bénéficié de MILDA (soit un taux de réussite de 101%) dans six régions ciblées. Un effort collectif est nécessaire pour pérenniser la lutte contre le paludisme dans l´ère COVID-19.

Prof. Mahmoud Sani moderated the third part of the Pre-Congress Workshop, the PASCAR Heart Failure Course, facilitated by Prof. Mahmoud Sani, Prof. Zaheer Yousef, Prof. Albertino Damasceno, Prof. Yacoub Musa, Prof. Anders Bararsa, and Prof. Karen Sliwa. To date, PASCAR's influence on the continent has continued to grow, and PASCAR is now Africa's foremost umbrella organization for national professional societies in cardiovascular medicine and surgery. African cardiologists first conceived the idea of forming a Pan African Society of Cardiology (PASCAR) in the 1970s, as the focus of the World Congress of Cardiology was solely on Europe and North America.

In sub-Saharan Africa, little is known about pulmonary hypertension in left heart disease (PH-LHD). We used multivariate logistic and cox-hazard proportional regression models to examine factors associated with increased right ventricular systolic pressure (RVSP) and the effect of real-world HIV status scenarios on 6-month survival rate in the Pan African Pulmonary Hypertension Cohort (PAPUCO) study, a prospective cohort from four African countries. Exposure to biomass fuel smoke (aOR, 95%CI 3.07, 1.02–9.28), moderate to severe NYHA/FC III/IV (aOR, 95%CI 4.18, 1.01–17.38), and unknown HIV status (aOR, 95%CI 2.73, 0.96–7.73) predicted moderate to severe RVSP at the time of presentation. Six months later, HIV infection, moderate-to-severe NYHA/FC, and alcohol consumption were associated with decreased survival probabilities. Upon adjusting for HIV infection, it was observed that an incremental rise in RVSP (1 mmHg) and inter-ventricular septal thickness (1 mm) resulted in an 8% (aHR, 95%CI 1.08, 1.02–1.13) and 20% (aHR, 95%CI 1.2, 1.00–1.43) increase in the probability of mortality due to PH-LHD. In contrast, the risk of death from PH-LHD was reduced by 23% for each additional unit of BMI. (aHR, 95%CI 0.77, 0.59–1.00). In conclusion, the present study offers insights into the determinants that are notably linked to unfavorable survival outcomes in patients with pulmonary hypertension due to left heart disease. Certain factors identified in this study are readily evaluable and amenable to modification, even in settings with limited resources. [ABSTRACT FROM AUTHOR]

Introduction: over the last decade, insecurity in the Lake Chad Basin has triggered an unprecedented humanitarian crisis in the Niger's Diffa Region with a significant population movement. In this humanitarian setting, we reviewed the implementation process and the contribution of temperature screening and handwashing practice at points of entry as part of non-pharmaceutical interventions against COVID-19. Methods: in Diffa, border officers were trained on the fundamentals of infection prevention and control in relation to COVID-19 readiness and response and a 14-day district response team was constituted. To examine the significance of the implementation process of temperature screening and handwashing practices at points of entry, we conducted a secondary analysis of data submitted by the six health districts of the Diffa Region between March and July 2020. Results: travellers screened for fever ranged from 10,499 (in March 2020) to 62,441 (in April 2020) with the health districts of Diffa (mean: standard error of the mean: 25,999: 9,220) and of Bosso (mean: standard error of the mean: 30.4: 19.1) accounting for the most and the least of activities during the entire period, respectively. Overall, 125/169,475 travellers presented fever and were effectively quarantined. Only the Ngourti Health District reported travellers who declined handwashing (54/169,475); this was during the first three months of the first wave of the COVID-19 pandemic. Conclusion: we have documented a successful implementation of measures related to temperature screening with some unsubstantial denial of handwashing. Given the importance of border traffic due to insecurity in the Diffa Region, maintaining temperature screening and handwashing in this humanitarian setting is necessary but requires coordinated actions of all stakeholders involved in the region.

Pulmonary rehabilitation (PR) is an integral part of the management of patients with chronic respiratory diseases. However, there is limited information available on the effectiveness and practice of PR in Africa. This study was conducted to examine the prevalence, structure, and organization of PR in Africa, as well as its substance and claimed efficacy. We conducted a multimethod study involving systematic review of PR studies (obtained from PubMed, Google Scholar, and Cochrane databases) and a webbased survey of African healthcare professionals engaged in PR (using a standardized questionnaire). The review included papers on at least one component of PR in Africa and excluded those on PR from other continents or assessing pulmonary disorders in general without PR, cardiorehabilitation, or physiotherapy practice in general in Africa. The Cochrane risk of bias and the Newcastle Ottawa scale instruments were used to assess the quality of included studies. We narratively synthesised data across the studies to produce a holistic picture. Of the 14 studies included for qualitative synthesis, seven were randomized controlled trials on the effectiveness of PR treatments with a total number of 333 participants. Of the 39 surveys mailed to health professionals working in Africa, only 14 (35.8%) were returned. We found aerobic exercise and breathing exercises were the most used technique and that quality of life, exercise capacity, and lung function improved significantly after PR treatments. There were differences in the duration, frequency, and length of the programs across the continent. Half of the respondents indicated that their institutions had one or more PR programs for inpatient, outpatient, maintenance, and/or homebased programs. Additionally, aerobic activities, upper and lower extremity strength training were the most frequently used exercise modalities in PR programs, followed by breathing exercises. Pulmonary rehabilitation is understudied in Africa, but it has been linked to improved lung function, exercise capacity, and quality of life. There is a need to invest in techniques tailored to the continent to enhance the implementation of pulmonary rehabilitation in Africa. [ABSTRACT FROM AUTHOR]

The article discusses the various health hazards from volcanic eruptions by citing the eruption of Mount Nyiragongo in the Democratic Republic of Congo (DRC) in May 2021. Other topics include the studies on the immediate and longer-term effects of volcanic gas and ash inhalation on mental health, and other volcanic emissions like hydrogen fluoride, hydrogen sulfide, and hydrogen chloride.

The implementation of electronic data collection during supportive supervision visits (ISS) using the Open Data Kits (ODK) Collection in Niger has provided a factual basis for monitoring the performance of the Polio eradication program (PEP) and the immunization program. With the notification of the first case of COVID-19 on 19 March 2020, there was a rapid need for quality knowledge to monitor the pandemic. For the first time in Niger, we initiated a six-month (May to October 2020) joint ISS-COVID-19 surveillance program to improve and monitor healthcare workers' performance to efficiently investigate COVID-19 cases in eight provinces. Overall, 1,378 ISS visits were performed through 390 health facilities, during which 4,638 health workers were trained and 527,151 medical records were reviewed, of which 28 suspected cases of COVID-19 were found. Field visits for contact tracing in their communities were accomplished and closed monitoring ensured until full recovery. Building on the tradition of PEP, a problem-solving process, feedback and on-the-job training on COVID-19 surveillance is set to enhance notification in the coming weeks and months. This is facilitated by accurate use of ODK Collect for real-time data surveillance successfully implemented. Other topics in the briefing included fundamentals of infection prevention and control for COVID-19 for both health professionals and community leaders. From this experience, the ISS has emerged as a key component of COVID-19 surveillance, especially in regions with a fragile health system. Our observation is a step forward for pragmatic interventional studies. [ABSTRACT FROM AUTHOR]

Introduction: the COVID-19 pandemic has spread across all countries in Africa, with much of the model forecasting disastrous results owing to weak health services and political uncertainty. In Niger, an adaptive solution to the COVID-19 pandemic has been implemented by community-based surveillance system (CBS) to complement passive case-finding in health systems. Methods: the CBS program was designed to use the current CBS polio network spanning 37 health districts in six regions. Between April and November 2020, 150 community health workers (CHWs) were equipped to improve integrated disease surveillance and response (IDSR) preparedness and response to the COVID-19 pandemic. We retrospectively analysed the health data of the National Health Information System to describe the effect of CBS in COVID-19 surveillance. Results: overall, trained CHWs were able to raise awareness among 2,681,642 persons regarding COVID-19 preventions and controls strategies. They reported 143 (84%) valid alerts resulting in two positive COVID-19 cases missing in the community. In addition, CHWs added to the contact tracing of 37 individuals and informed about the deaths in the community. Conclusion: community-based surveillance improved COVID-19 response in Niger. Logistic assistance and ongoing training are the foundations for increasing and sustaining the sensitivity of CBS systems in response to the COVID-19 pandemic to deter hotspots across countries.

Background: The extraction and processing of copper and cobalt in the African Copperbelt in the Democratic Republic of Congo have led to substantial environmental pollution, causing concerns about possible adverse effects on human health, including birth defects. Cases: We report three neonates with clinically diagnosed holoprosencephaly who were part of a case–control study performed in Lubumbashi between February 2013 and February 2015. One mother had a high concentration of uranium in urine, and high manganese concentrations were found in blood of another mother and in cord blood of one infant. Two of the three fathers had a mining‐related job. Discussion: We hypothesize that these cases of holoprosencephaly were connected to mining‐related pollution, possibly via epigenetic alterations induced by paternal occupational exposure to toxic metals.
