Intervention accelerator to prevent and respond to abuse of older people: insights from key promising interventions.

Globally, abuse of older people (AOP) affects one in six individuals aged 60 years and older every year. Despite the widespread prevalence of AOP, evidence-based interventions for preventing and responding to this issue are insufficient. To address this gap, WHO proposed an initiative to accelerate the development of effective interventions for AOP across all country income levels.

Evolution of Pfdhps and Pfdhfr mutations before and after adopting seasonal malaria chemoprevention in Nanoro, Burkina Faso.

Seasonal Malaria Chemoprevention consisting of monthly administration of amodiaquine/sulfadoxine-pyrimethamine to children aged 3-59 months during the transmission season could promote SP-resistance. Mutations in dihydrofolate reductase (Pfdhfr) and dihydropteroate synthase (Pfdhps) genes were assessed before and after SMC adoption in Burkina Faso. A total of 769 dried blood spots were selected from studies conducted in Nanoro, Burkina Faso, between 2010 and 2020.

Trend of N86Y and Y184F Mutations in Pfmdr1 Gene in Children Under Seasonal Malaria Chemoprevention Coverage in Nanoro, Burkina Faso.

Background: Seasonal malaria chemoprevention (SMC) is an effective malaria preventive intervention in sub-Sahara Africa. However, as with any other drug-based intervention, the large-scale deployment of this strategy could lead to Amodiaquine plus Sulfadoxine-Pyrimethamine (AQSP) drug pressure on the circulating parasites population with selection for specific alleles that could compromise the impact of the intervention in the near future. This study aimed to assess the distribution of the Pfmdr1 mutation involved in resistance to AQ before and after the annual campaign of SMC in the health district of Nanoro.

Exploring Antibiotic Use in the Community: A Household-Based Survey Using the Drug Bag Method in Rural Burkina Faso.

In Burkina Faso, there is lack of awareness of antibiotic use at the community level. This study aims to generate information on the commonly used antibiotics along with the reasons for which they have been used in rural Burkina Faso. The drug bag method was employed to collect information from 423 households in the health district of Nanoro.

Prodrug activation in malaria parasites mediated by an imported erythrocyte esterase, acylpeptide hydrolase (APEH).

The continued emergence of antimalarial drug resistance highlights the need to develop new antimalarial therapies. Unfortunately, new drug development is often hampered by poor drug-like properties of lead compounds. Prodrugging temporarily masks undesirable compound features, improving bioavailability and target penetration.

Prevalence of asymptomatic malaria at the communal level in Burkina Faso: an application of the small area estimation approach.

Background: In malaria-endemic countries, asymptomatic carriers of plasmodium represent an important reservoir for malaria transmission. Estimating the burden at a fine scale and identifying areas at high risk of asymptomatic carriage are important to guide malaria control strategies. This study aimed to estimate the prevalence of asymptomatic carriage at the communal level in Burkina Faso, the smallest geographical entity from which a local development policy can be driven.

Leaves Extracts Enhance Cefotaxime Bactericidal Effects and Quench the Biofilm Formation in Methicillin-Resistant ATCC 43300.

Background: The emergence of the multidrug-resistant bacteria strain has become a global world crisis. This study was designed to evaluate the antibiofilm and synergistic effects of leaf extracts on the activity of cefotaxime against the methicillin-resistant ().

Methods: The synergistic effect of methanol and dichloromethane extracts on the bactericidal activity of cefotaxime was determined by using the antibiotic susceptibility test on agar medium.

Antibiotic use by clinical presentation across all healthcare providers in rural Burkina Faso: a healthcare visit exit survey.

Background: To guide antibiotic stewardship interventions, understanding for what indications antibiotics are used is essential.

Methods: In rural Burkina Faso, we measured antibiotic dispensing across all healthcare providers. From October 2021 to February 2022, we surveyed patients in Nanoro district, Burkina Faso, following visits to health centres (3), pharmacies (2), informal medicine vendors (5) and inpatients in health centres.
