Introduction: In low-and-middle-income-countries (LMIC), viral suppression is defined as plasma viral load (PVL) below 1000 copies/mL (low-level viremia [LLV]) and threshold for HIV drug resistance (HIVDR) testing. However, there is evidence that drug resistance mutations (DRMs) may emerge at LLV, thus compromising antiretroviral treatment (ART) response We evaluated sequencing success rates (SSR) at LLV, described HIVDR profiles and adequacy with potential efficacy of tenofovir-lamivudine-dolutegravir (TLD).
Methods: A cross-sectional study was conducted among individuals with LLV at the Chantal BIYA International Reference Centre, Yaoundé, Cameroon from January 2020 through August 2021.

The present study aimed to evaluate the antimicrobial activity of aqueous extracts of the mixture of spices used as accompanying soup of braised fish against multidrug resistant (MDR) bacteria isolated from raw and braised fish collected in the city of Bangangté, Cameroon. A survey was conducted in the city of Bangangté to diagnose the braising fish processes. Pathogens were isolated from raw and braised fish samples collected in fish farms and selling points, and their susceptibility to 16 commonly used antibiotics was tested using the Kirby-Bauer disk diffusion method.

This study introduces a ground-breaking approach, the Whale Optimization Algorithm (WOA)-based multivariate exponential smoothing Grey-Holt (GMHES) model, designed for electricity price forecasting. Key features of the proposed WOA-GMHES(1,N) model include leveraging historical data to comprehend the underlying trends in electricity prices and utilizing the WOA algorithm for adaptive optimization of model parameters to capture evolving market dynamics. Evaluating the model on authentic high- and low-voltage electricity price data from Cameroon demonstrates its superiority over competing models.

Evidence on long-term outcomes of children receiving antiretroviral therapy (ART) in low- and middle-income countries (LMICs) is of utmost importance to optimize current and future therapeutic strategies for HIV. We sought to ascertain the long-term responses among ART-experienced children and their potential implications. A retrospective, observational, facility-based cohort study was conducted among 136 ART-experienced children monitored for 10 years (2007-2017) at the Essos Hospital Centre in Yaoundé, 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.

Background: Infection prevention and control (IPC) helps prevent disease transmission in healthcare facilities. There is a dearth of information on the implementation of IPC during the COVID-19 outbreak in Cameroon using the recommended WHO COVID-19 IPC scorecard tool. The present study assessed healthcare facilities' compliance to IPC by continuous assessments, with an evaluation of the tool using the hierarchy of control theory.

Objectives: Infection prevention and control (IPC) contributes to the reduction of healthcare associated infections. Notwithstanding the global attention with available guidelines and tools, low- and middle-income countries (LMICs) still struggle to put into place effective IPC programmes. Here, we use a socioecological approach to summarize the findings of a recent workshop on the implementation of IPC activities in Cameroon.

The CMCs are viable materials for applications in industry and process innovation for removing heavy metal ions since they may be used in static and dynamic adsorption processes. It is necessary to develop simple, low-cost water treatment methods that use organic, biodegradable polymers such as nanomaterial-modified cellulose microcrystals. The column technique was used to investigate the effects of operational parameters such as pH, bed depth, concentration and flow rate.

Reliability is a crucial factor to consider for multi-level inverters (MLIs) used in industrial applications. With the increasing number of power semiconductor devices, the potential for defects to significantly degrade the overall system is heightened. A highly effective fault-detection technique is required to minimize the impact of faults.

Objectives: Chest x-ray (CXR) plays an important role in childhood tuberculosis (TB) diagnosis, but access to quality CXR remains a major challenge in resource-limited settings. Digital CXR (d-CXR) can solve some image quality issues and facilitate their transfer for quality control. We assess the implementation of introducing d-CXR in 12 district hospitals (DHs) in 2021-2022 across Cambodia, Cameroon, Ivory Coast, Mozambique, Sierra Leone and Uganda as part of the TB-speed decentralisation study on childhood TB diagnosis.

Background: Psychological and social support for adolescents living with HIV remains undocumented and unaddressed in Central Africa. This study aimed at assessing effectiveness of a peer-facilitated community-based support model in improving retention in care among adolescents living with HIV and attending care in Chantal Biya Foundation, Yaounde, Cameroon.
Materials And Methods: We conducted an analysis of adolescents aged 10-19 years old, perinatally infected with HIV, on follow-up in the Day Care Unit of a reference hospital in Yaounde, Cameroon, and enrolled in the IAS-CIPHER-2021/1214-ATE-SMAVI, a individually randomized controlled trial.
