Background: It is crucial to consider cultural, religious, and socio-behavioural factors that may influence the acceptability of Minimally Invasive Tissues Sampling (MITS). MITS is being used to understand the causes of child death and conducted in nine countries within Africa and South Asia with the highest child mortality. Progress has been made in the development of laboratory infrastructures and training for physicians to do MITS, but many communities are concerned about the religious acceptability of taking samples from deceased children.

Introduction: Malnutrition contributes to 45% of all childhood deaths globally, but these modelled estimates lack direct measurements in countries with high malnutrition and under-5 mortality rates. We investigated malnutrition's role in infant and child deaths in the Child Health and Mortality Prevention Surveillance (CHAMPS) network.

Methods: We analysed CHAMPS data from seven sites (Bangladesh, Ethiopia, Kenya, Mali, Mozambique, Sierra Leone and South Africa) collected between 2016 and 2023.

Article Synopsis
  • The study investigates the role of meningitis in child mortality under five years old, particularly focusing on data from six sub-Saharan African countries and Bangladesh.
  • It employs post-mortem minimally invasive tissue sampling (MITS) to identify the causes of death and pathogens responsible for meningitis in this age group from December 2016 to December 2023.
  • Findings reveal that meningitis contributed to 7% of child deaths, with common pathogens identified being Acinetobacter baumannii and Klebsiella pneumoniae, particularly affecting neonates and infants.

Transfection efficiency is a critical parameter in gene therapy and molecular biology, representing the success rate at which nucleic acids are introduced and expressed in target cells. The combination of aptamers with nanotechnology-based delivery systems has demonstrated remarkable improvements in the transfection efficiency of therapeutic agents and holds significant potential for advancing gene therapy and the development of targeted treatments for various diseases, including cancer. In this work, cationic carbosilane dendritic systems are presented as an alternative to commercial transfection agents, demonstrating an increase in transfection efficiency when used for the internalization of apMNKQ2, an aptamer selected against a target in cancer.

Importance: The emergence of acute neurological symptoms in children necessitates immediate intervention. Although low- and middle-income countries (LMICs) bear the highest burden of neurological diseases, there is a scarcity of diagnostic and therapeutic resources. Therefore, current understanding of the etiology of neurological emergencies in LMICs relies mainly on clinical diagnoses and verbal autopsies.
