and markers of resistance to sulfadoxine-pyrimethamine five years (2016-2020) after the implementation of seasonal malaria chemoprevention in Cameroon.

Background: Antimalarial drug resistance is a major challenge in the fight against malaria. Cameroon implemented seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine and amodiaquine (SPAQ) to over 1.5 million children aged 3-59 months from 2016, raising concerns whether drug pressure may lead to a selection of known parasite resistance mutations.

Evaluating the performance of a virtual platform 'T-BOM' for mentorship in tropical diseases research among early career scientists: Insights from a pilot in Nigeria and other resource-limited settings.

Background: Research mentorship plays a crucial role in advancing science. However, there are limited virtual platforms for cultivating mentorship among early career infectious diseases researchers in resource challenged settings. This study reports the findings from the utilization of a recently developed virtual mentorship platform, including its achievements, challenges and needs.

New records of Gemeneta opilionoides (Orthoptera, Catantopinae) in the world's second largest rainforest.

Gemeneta opilionoides (Bolívar 1905) is a rare grasshopper presently known from three localities, Biafra (in Equatorial Guinea), Makak, and Ngutadjap (in Cameroon). Few data exist on the biology and ecology of this species in the central Africa rainforests, while its natural habitat is being rapidly destroyed by deforestation. It has been recently found at two new localities, Ngoyla in Cameroon, and Bioko Island in Equatorial Guinea.

Phenolic compounds, antioxidant and antileishmanial activities of kombucha as affected by fermentation time.

Objective: Study the impact of fermentation time on the phytochemical properties, antioxidant and antileishmanial activities.

Materials And Methods: The preparation of Kombucha tea by fermentation was performed under aseptic conditions and symbiotic culture of bacteria and yeast (SCOBY) layer was maintained in culture for continuous growth in a water-sugar (4 L-500 g) mixture for 7, 14, 21, 28 and 35 days. The process of preparation was performed using a decoction.

Amplification of very low output voltages of PV panels using a Duffing oscillator.

We are interested in the amplification of very low voltages produced by solar cells during sunset or weak sunshine. The study uses a device consisting of a Duffing oscillator, which amplifies and automatically regulates a low-voltage input, an inverter that reverses the negative voltage of one of the outputs of the oscillator, and a summing device to add the voltages of the two oscillator outputs. Experimental and theoretical investigations are conducted, and it is observed from the results that the output voltage can reach to 7.

The Potential for Bouillon Fortification to Reduce Dietary Micronutrient Inadequacy: Modeling Analyses Using National Survey Data from Cameroon, Ghana, and Haiti.

Background: Bouillon is commonly consumed in some countries where micronutrient deficiencies are prevalent, but it has not been widely adopted as a micronutrient fortification vehicle.

Objectives: We modeled the potential impacts of bouillon fortification on dietary micronutrient adequacy to inform future discussions around bouillon fortification programs.

Methods: We analyzed the dietary intake of women of reproductive age (WRA) and 1- to 5-y-old children from a national dietary survey in Cameroon, and "apparent intake" (using the nutrient density approach) of WRA, children, and men from 3 household surveys in Cameroon, Ghana, and Haiti.

Developing a modern radiotherapy department in a rural hospital in Cameroon: The Mbingo experience.

Although radiotherapy is critical for cancer cure and palliation, access to such expensive and sophisticated technology is very limited in low- and middle-income countries (LMIC). Cancer incidence in Africa is currently 1.5 million case per year, thus urgent and innovative solutions are required to build necessary infrastructure needed to address this global health challenge.

Ankle Sprain Recurrence and Rehabilitation Among Athletes: A Case Study in the West Region of Cameroon.

Objectives: To investigate the prevalence, risk factors, and impact of physiotherapy on ankle sprain recurrence among professional and amateur athletes in the West region of Cameroon.

Methods: Cross-sectional study from February to July 2024 in the West region of Cameroon sports clubs. Professional and amateur athletes practice their sport at least three times a week.

Characterization of human exposure to Anopheles and Aedes bites using antibody-based biomarkers in rural zone of Cameroon.

Malaria and Aedes-borne diseases remain major causes of mortality, morbidity, and disability in most developing countries. Surveillance of transmission patterns associated with vector control remains strategic for combating these diseases. Due to the limitions of current surveillance tools used to assess human exposure to mosquito bites, human antibody (Ab) responses to salivary peptides from Anopheles (gSG6-P1) and Aedes (Nterm-34kDa) are increasingly being used to measure direct human-Anopheles or Aedes contact.

Seroprevalence and hematological profile of dengue among healthy inhabitants of Mayo Kebbi province: South of Tchad.

Introduction: Dengue is one of the most serious and rapidly spreading major mosquito borne diseases in the world. Despite many acute febrile illnesses in Tchad, the burden of illness due to dengue in the country is largely unknown. Hence, the present study aimed to determine the seroprevalence of dengue viral (DENV) infection and its association with hematological parameters.

Rapid test for hepatitis B core-related antigen to identify people living with hepatitis B having high viral load in Cameroon.

This study presents a retrospective assessment of the diagnostic performance of the newly developed hepatitis B core-related antigen rapid diagnostic test (HBcrAg-RDT) in detecting plasma samples with elevated hepatitis B virus (HBV) DNA levels (≥200,000 IU/ml) in Yaoundé, Cameroon. Samples were collected consecutively from treatment-naïve adults living with HBV between January 1, 2021, and June 30, 2023. Analyzing 146 samples from participants with a median age of 36 years, the HBcrAg-RDT exhibited a sensitivity of 97.

African bat database: curated data of occurrences, distributions and conservation metrics for sub-Saharan bats.

Accurate knowledge of species distributions is foundational for effective conservation efforts. Bats are a diverse group of mammals, with important roles in ecosystem functioning. However, our understanding of bats and their ecological importance is hindered by poorly defined ranges, mostly as a result of under-recording.

Monitoring forest cover and land use change in the Congo Basin under IPCC climate change scenarios.

The Congo Basin tropical forests are home to many endemic and endangered species, and a global hotspot for forest fragmentation and loss. Yet, little has been done to document the region's rapid deforestation, assess its effects and consequences, or project future forest cover loss to aid in effective planning. Here we applied the Random Forest (RF) supervised classification algorithm in Google Earth Engine (GEE) to map and quantify decadal changes in forest cover and land use (LCLU) in the Congo Basin between 1990 and 2020.

Preliminary study of the role of social support in cycles of intimate partner violence.

Parents' experiences of IPV are associated with an increased risk for their children to experience IPV. However, the factors that may contribute to intergenerational IPV, particularly between adult mothers and daughters, are still poorly understood. To fill this gap in the literature, this preliminary study examines the moderating role of social support in IPV cycles among Cameroonian mother-daughter dyads.

How Is Health System Resilience Being Assessed? A Scoping Review.

Background: It is commonly argued that resilient health systems ensure the well-being of populations even under critical conditions, whereas poorly resilient ones may be disrupted and collapse. We aimed to examine how health system resilience can be assessed as this issue is still under debate.

Methods: We conducted a scoping review of peer-reviewed and grey literature published up to March 2022, following the Joanna Briggs Institute (JBI) guidance.
