Pathological Sequelae of SARS-CoV-2: A Review for Clinicians.

The Coronavirus Disease 2019 (COVID-19) pandemic, driven by the novel coronavirus and its variants, has caused over 518 million infections and 6.25 million deaths globally, leading to a significant health crisis. Beyond its primary respiratory impact, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has been implicated in various extra-pulmonary complications.

Mosquito breeding water parameters are important determinants for Microsporidia MB in the aquatic stages of Anopheles species.

Background: Microsporidia MB disrupts Plasmodium development in Anopheles mosquitoes, making it a possible biocontrol tool for malaria. As a tool for vector/disease control, its ecological distribution and the factors that determine their occurrence must be defined. We investigated the frequency of Microsporidia MB in Anopheles mosquitoes across selected sites in northern and southern Ghana, as well as the physicochemical parameters of mosquito breeding water that are associated with the occurrence of the fungus, by fitting regression models.

Advancing poliovirus eradication: lessons learned from piloting direct molecular detection of polioviruses in high-risk and priority geographies.

Unlabelled: In the Global Polio Laboratory Network (GPLN), poliovirus (PV) screening results from acute flaccid paralysis (AFP) surveillance is based on virus isolation (VI) through cell culture, entailing long turnaround times and the amplification of live poliovirus. An alternative Direct Detection strategy (DD-ITD) for screening viral nucleic acid from stools, bypassing the need for virus culture, has been developed and extensively validated by GPLN partners. A multi-laboratory demonstration project was conceived to field-test the DD-ITD method by GPLN laboratories from the WHO African, Western Pacific, and Eastern Mediterranean regions, where wild serotype 1 or vaccine-derived polioviruses still circulate.

Prediction of Human Papillomavirus-Host Oncoprotein Interactions Using Deep Learning.

Background: Human papillomavirus (HPV) causes disease through complex interactions between viral and host proteins, with the PI3K signaling pathway playing a key role. Proteins like AKT, IQGAP1, and MMP16 are involved in HPV-related cancer development. Traditional methods for studying protein-protein interactions (PPIs) are labor-intensive and time-consuming.

Impact of dosing schedules on performance of rotavirus vaccines in Ghana.

There is currently limited evidence regarding how the rotavirus vaccine dosing schedule might be adjusted to improve vaccine performance. We quantified the impact of the previously implemented 6/10-week Rotarix vaccine (RV1) in Ghana to the model-predicted impact for other vaccine dosing schedules across three hospitals and the entire country. Compared to no vaccination, the model-estimated median percentage reductions in rotavirus ranged from 28 to 85% and 12 to 71% among children <1 and <5 years old, respectively.

Copy number variants underlie major selective sweeps in insecticide resistance genes in Anopheles arabiensis.

To keep ahead of the evolution of resistance to insecticides in mosquitoes, national malaria control programmes must make use of a range of insecticides, both old and new, while monitoring resistance mechanisms. The outdoor-biting malaria vector Anopheles arabiensis is of increasing concern for malaria transmission because it is apparently less susceptible to many indoor control interventions, yet knowledge of its mechanisms of resistance remains limited. Furthermore, comparatively little is known in general about resistance to non-pyrethroid insecticides such as pirimiphos-methyl (PM), which are crucial for effective control in the context of globally high resistance to pyrethroids.

Molecular detection of dengue virus from febrile patients in Ghana.

Background: Viral hemorrhagic fevers (VHFs) belong to a group of viral infectious diseases that interfere with the blood's clotting mechanism. VHF has a wide host range, including bats, rodents, or arthropods such as mosquitoes and ticks. Most VHFs emerge suddenly as outbreaks, making it difficult to predict occurrence.

Multidrug-Resistant Bacteria in Aquaculture Systems in Accra, Ghana.

Background: Antibiotic resistance (ABR) poses a critical global health challenge, necessitating its surveillance across both human and animal health sectors. This study evaluated ABR in bacteria harboured in reared inland fishes sold in Accra and the pond water from which they originated.

Method: The study was cross-sectional, involving fishes and water sampled from 80 ponds.

Fc-Afucosylation of VAR2CSA-Specific Immunoglobulin G and Clinical Immunity to Placental Plasmodium falciparum Malaria.

Background: Acquired immunity to Plasmodium falciparum malaria is mainly mediated by immunoglobulin G (IgG) targeting erythrocyte membrane protein 1 (PfEMP1). These adhesins mediate infected erythrocyte (IE) sequestration, protecting IEs from splenic destruction. PfEMP1-specific IgG is therefore thought to protect mainly by inhibiting IE sequestration.

Exploring the relationship between genetic diversity and antimalarial drugs resistance markers in a malaria-endemic region of Burkina Faso.

Introduction: the diversity of Plasmodium falciparum genotypes affects the dynamics of malaria transmission and is thought to be one of the factors hampering malaria control efforts. This study aimed to investigate the relationship between Plasmodium falciparum genetic diversity and chloroquine and sulfadoxine-pyrimethamine resistance markers in malaria endemic areas of Burkina Faso.

Methods: in a cross-sectional study, populations residing in Nouna health district were randomly recruited.

The use of telehealth technology for lifestyle modification among patients with hypertension in Nigeria and Ghana.

Introduction: Sedentary lifestyle and consumption of an unhealthy diet are significantly associated with hypertension in Nigeria and Ghana. Increasing the uptake of physical activity and diet rich in fruits and vegetables has been a challenge in the region. This study aimed at assessing the effect of a mobile health intervention (mhealth) on physical activity, and fruits and vegetables intake in patients with hypertension in Nigeria and Ghana.

Enhancing clinical microbiology for genomic surveillance of antimicrobial resistance implementation in Africa.

Surveillance is essential in the fight against antimicrobial resistance (AMR), to monitor the extent of resistance, inform prevention, control measures, and evaluate intervention progress. Traditional surveillance methods based on phenotypic antimicrobial susceptibility data offer important but limited insights into resistance mechanisms, transmission networks, and spread patterns of resistant bacterial strains. Fortunately, genomic technologies are increasingly accessible and can overcome these limitations.

Extended-spectrum beta-lactamase-producing Enterobacterales in human health: Experience from the tricycle project, Ghana.

Background: Vulnerable groups, such as pregnant women, are at increased risk of potentially life-threatening infections with extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E) for both mother and newborn. However, data regarding ESBL-E carriage and associated risk factors in Ghanaian pregnant women remain scarce.

Objective: This study aimed to determine the prevalence of ESBL-E carriage and its associated risk factors among pregnant women attending the antenatal clinic at the Korle Bu Teaching Hospital.

Identification of complex Plasmodium falciparum genetic backgrounds circulating in Africa: a multicountry genomic epidemiology analysis.

Background: The population structure of the malaria parasite Plasmodium falciparum can reveal underlying adaptive evolutionary processes. Selective pressures to maintain complex genetic backgrounds can encourage inbreeding, producing distinct parasite clusters identifiable by population structure analyses.

Methods: We analysed population structure in 3783 P falciparum genomes from 21 countries across Africa, provided by the MalariaGEN Pf7 dataset.
