Context: Tuberculosis (TB) diagnosis in children remains challenging due to the paucibacillary nature of specimens and the difficulty in obtaining suitable samples. The use of alternative samples like nasopharyngeal aspirate (NPA) and stools, alongside Xpert MTB/RIF testing, offers promising improvements.

Objective: This study aimed to assess the diagnostic performance of the Xpert MTB/RIF test on NPA and stool samples for detecting intrathoracic TB in children from Madagascar, Cameroon, and Ivory Coast.

This article explores the challenges faced by a multifaith chaplaincy team in a Dutch health care organization when searching for a shared professional identity regarding the role of worldview and religion. Using boundary theory, we show how the diverse worldviews and the contradictory visions on their role for chaplaincy's professional identity led to misunderstandings and conflict. However, open and respectful dialogue about these differences helped clarify disagreements and identify common ground.

Purpose: Tumor next-generation sequencing (NGS) testing identifies possible germline pathogenic variants (PGPVs), creating a dilemma for appropriate recognition, triage, and management. The objective of this study was to determine the clinical utility of an institutional molecular tumor board (MTB) in assessing tumor NGS reports for PGPVs.

Methods: Our institutional MTB reviews all NGS reports to provide treatment and further testing recommendations, including genetic counseling referral and consideration of genetic testing (GC/GT).

Article Synopsis
  • A specific type of regulatory B cells in newborns (nBreg) uses IL-10 to limit the production of IgM antibodies, which helps control the immune response after initial activation.
  • *By analyzing these nBreg cells in fetal and neonatal intestines, researchers identified their antibody repertoire and demonstrated that they produce antibodies that react to various bacteria in the early microbiota.
  • *This study suggests that nBreg populations are crucial for shaping the microbiome during early life by influencing bacterial diversity and metabolism.*

Human cytogenetic biomonitoring (HCB) has long been used to evaluate the potential effects of work environments on the DNA integrity of workers. However, HCB studies on the genotoxic effects of occupational exposure to extremely low-frequency electromagnetic fields (ELF-MFs) were limited by the quality of the exposure assessment. More specifically, concerns were raised regarding the method of exposure assessment, the selection of exposure metrics, and the definition of exposure group.
