Article Synopsis
  • The study highlights the issue of insecticide resistance among malaria vector mosquitoes in urban settings of Kisumu County, Kenya, where rising urbanization impacts control effectiveness.
  • Urban areas showed a significant dominance of Anopheles arabiensis, demonstrating high resistance to deltamethrin, while An. gambiae was more prevalent in rural settings.
  • The study employed various methods including WHO susceptibility tests and genetic analysis to reveal the underlying mechanisms of resistance, indicating a need for targeted vector control strategies in urban populations.

Foxtail millet bran soluble dietary fibre (MBSDF) is a dietary compound with various bioactivities, potentially modulated by the gut microbiota. To elucidate this bioregulatory mechanism, this study focused on the structureal composition and in vitro fermentation characteristics of MBSDF. The results revealed that MBSDF has a molecular weight of 18.

Background: Increasing urbanization in tropical Africa may create new niches for malaria vectors, potentially leading to higher disease transmission rates. Vector control efforts remain largely targeted at ecologically rural bio-complexities with multiple hosts. Understanding mosquito species composition, ecology, host diversity and biting behavior in urban areas is crucial for planning effective control.

Background: Poor early childhood development (ECD) is a major global health concern that is associated with various adverse outcomes over the lifecourse. Parenting interventions especially during the earliest years of life can benefit ECD. However, there is limited evidence from Kenya about the effectiveness of parenting interventions for improving ECD outcomes especially across rural disadvantaged communities.

Air pollution is the leading environmental cause of death globally, and most mortality occurs in resource-limited settings such as sub-Saharan Africa. The African continent experiences some of the worst ambient air pollution in the world, yet there are relatively little African data characterizing ambient pollutant levels and source admixtures. In Uganda, ambient PM levels exceed international health standards.
