For longer than a century, the "meningitis belt" of sub-Saharan Africa has experienced the largest-ever global meningitis epidemic. Whereas HIV-associated immunosuppression drives higher susceptibility to environmental infectious organisms with tropism for the central nervous system (CNS), most diagnostic laboratories in the belt stick to , , and . has been the leading cause of death (incidence, 89%; death, 75%). To establish whether diagnostic services target geographically important pathogens, there is a need to know the current spectrum of etiology. Given Africa's agro-silvo-pastoralism, the One Health diagnostic approach is recommended. Considering multipathogen detection capacity, needed speed for corticosteroid therapy decision, and susceptibility/resistance to antimicrobials with improved CNS penetration, proposed laboratory categorization will help neurologists to choose suitable services.

Purpose: Human epidermal growth factor receptor 2 (HER2)-targeted therapies have shown promise in treating -amplified metastatic colorectal cancer (mCRC). Identifying optimal biomarkers for treatment decisions remains challenging. This study explores the potential of artificial intelligence (AI) in predicting treatment responses to trastuzumab plus pertuzumab (TP) in patients with -amplified mCRC from the phase II TRIUMPH trial.

Eleven countries have been certified as malaria free since 2016, but none of these are in subSaharan Africa where elimination challenges are unique. The 1-3-7 focus investigation approach is an implementation strategy that requires case reporting, case investigation/classification, and focal classification/response to be completed one, three, and seven days, respectively, after index case diagnosis. Real-time short-messaging-service reports are sent at each step to add accountability and data transparency.

More community-based studies are required to understand better the actual burden of epilepsy in these areas and the difficulties in accessing healthcare.
Objective: To adapt and validate a household survey epilepsy-screening instrument in Shai-Osudoku and Ningo-Prampram District of Greater Accra Region, Ghana.
Inpatient Audiologic Services Facilitate Early Hearing Detection.

January 2025
Division of Clinical Therapies, Department of Audiology, Nationwide Children's Hospital, Columbus, OH.
Purpose: Infants needing neonatal intensive care unit (NICU) intervention have protracted timelines for diagnosis after not passing their newborn hearing screening despite being at higher risk for congenital hearing loss. The primary aim of this study was to evaluate the outcomes of early hearing detection for infants with a history of NICU admission. The secondary aim was to determine if diagnostic audiology services within the NICU setting accelerated diagnosis and intervention.

January 2025
National Center for Birth Defects Monitoring, West China Second University Hospital, Sichuan University, Chengdu, China.
Background: Seasonality in the incidence of congenital hypothyroidism (CH) has been identified in several countries and different conclusions have been drawn. The objective of this study was to examine whether this seasonality is also observable in China and how it manifests across different temperate zones.
Methods: Data on CH cases and screened neonates between January 1, 2014, and September 30, 2022, by year and season, were sourced from the Chinese Newborn Screening Information System.
