This paper analyses the credit constraints' effect on non-farm entrepreneurship entry decisions in Benin. Using data from a sample of 512 farmers, we determine the factors that influence credit constraints and then assess the effect of credit constraints on non-farm entrepreneurship decisions based on an endogenous switching probit model and propensity score matching (PSM). The results of endogenous switching regression reveal that age and access to extension services are the main determinants of credit constraints while age, sex, household size, marital status, education level and farmer-based organisation (FBO) membership significantly increase farmers' decisions to engage in non-farm entrepreneurship.

Background: Antiretroviral drugs in people living with HIV-1 (PLHIV-1) often trigger side effects which may lead to discontinuation or failure of treatment. Human Leukocyte Antigen B*57:01 (HLA-B*57:01) allele is known to predict hypersensitivity reactions to Abacavir. Very few data are available on the prevalence of HLA-B*57:01 allele in PLHIV-1 in African countries.

Article Synopsis
  • Regulatory T cells (Treg) are crucial for managing immune responses in newborns, especially regarding tolerance to maternal antigens and fighting infections at birth.
  • This study, focusing on newborns in West Africa, found that neonates with early-onset sepsis (EOS) had reduced Treg frequency and expression of the Foxp3 marker compared to healthy newborns with prenatal risk factors, indicating a compromised immune profile.
  • The findings suggest that specific Treg markers like CTLA-4, PD-1, and CD39 could serve as potential early diagnostic indicators for EOS, as their expression correlates with the severity and outcome of the condition.

Introduction: Innate immunity is crucial to reducing parasite burden and contributing to survival in severe malaria. Monocytes are key actors in the innate response and, like macrophages, are plastic cells whose function and phenotype are regulated by the signals from the microenvironment. In the context of cerebral malaria (CM), monocyte response constitutes an important issue to understand.

Background: Immune cells and cytokines have been linked to viremia dynamic and immune status during HIV infection. They may serve as useful biomarkers in the monitoring of people living with HIV-1 (PLHIV-1). The present work was aimed to assess whether cytokines and immune cell profiles may help in the therapeutic follow-up of PLHIV-1.
