In 2024, there have been increases in laboratory-confirmed infections caused by Mycoplasma pneumoniae worldwide. This case series highlights the increasing frequency of M. pneumoniae-positive PCR (polymerase chain reaction) specimens and an increased number of hospital admissions with M.

Surveillance efforts, however, are inconsistent in endemic regions such as in sub-Saharan Africa, due to fragmented reporting and limited diagnostic capacity for suspected cases, limiting successful monitoring and evaluation of vaccination campaigns. Here, we conducted a pilot study aiming to strengthen rabies surveillance by combining community-based surveillance with field-based diagnostic testing in pastoral and agro-pastoral communities in central Kenya; communities which are frequently marginalised from health systems.

We sought to delineate clinical, biochemical, and neuroimaging features of these disorders, together with outcomes after oral CoQ supplementation and the utility of peripheral blood mononuclear cell (PBMNC) CoQ levels in monitoring therapy.
Methods: This was a retrospective cohort study, registered as an audit at a specialist pediatric hospital (Registration Number: 3318) of 14 patients with genetically confirmed CoQ biosynthesis deficiency, including 13 previously unreported cases.
Article Synopsis
- HSV-1 primarily infects the oral and nasal areas before establishing latency in the trigeminal ganglion and can also infect the central nervous system (CNS) via specific pathways.
- Recent studies have highlighted the lack of detailed knowledge about which brain regions are affected during HSV-1 infections and how microglial responses differ across these regions.
- This study on a mouse model revealed a two-step spread of HSV-1 from the olfactory epithelium to select brain regions, along with varying activation levels of microglia, contributing to understanding HSV-1's role in neurological diseases.
Article Synopsis
- HSV-1 primarily infects the oral and nasal areas before becoming latent in the trigeminal ganglia and can also infect the central nervous system (CNS) through specific pathways.
- The study used a mouse model to observe how HSV-1 spreads through the olfactory epithelium and CNS, finding a distinct spread pattern and accompanying inflammatory response from immune cells.
- The research identified specific brain regions affected by HSV-1, revealing no involvement of the hippocampus or cortex, and highlighted varied microglial activation across different regions, suggesting implications for neurological diseases.
