AI Article Synopsis
- * Two studies were conducted on school-aged children in Uganda, revealing a GAS carriage rate of 15.9% and showing that 41.8% of sore throats tested were positive for GAS.
- * Findings indicate that GAS carriage and sore throat positivity rates in Uganda are higher than the global averages, highlighting a significant public health issue that could lead to serious complications like rheumatic fever and heart disease.
Article Abstract
Objectives: Group A β-hemolytic Streptococcus (GAS), also known as Streptococcus pyogenes, is responsible for an annual 600 million cases of acute pharyngitis globally, with 92% of those infections occurring in low-resource settings. Further knowledge of the acute streptococcal pharyngitis burden in low-resource settings is essential if serious post-streptococcal complications - rheumatic fever (RF) and its long-term sequel rheumatic heart disease (RHD) - are to be prevented.
Methods: Two studies were conducted in school-aged children (5-16 years): a cross-sectional study of streptococcal pharyngeal carriage followed by a prospective cohort study of streptococcal sore throat over 4 weeks from March to April 2017.
Results: The cross-sectional study revealed an overall prevalence of GAS carriage of 15.9% (79/496, 95% confidence interval 12.8-19.5%). Among 532 children enrolled in the prospective cohort study, 358 (67%) reported 528 sore throats, with 221 (41.1%) experiencing at least one GAS-positive sore throat. The overall GAS-positive rate for sore throat was 41.8% (221/528).
Conclusions: The GAS pharyngeal carriage rates seen in Uganda (15.9%, 95% confidence interval 12.8-19.5%) are higher than the most recent pooled results globally, at 12% (range 6-28%). Additionally, pilot data suggest a substantially higher percentage of sore throat that was GAS-positive (41.8%) compared to pooled global rates when active recruitment is employed.

Transesophageal endosonography in the diagnosis of sarcoidosis: a narrative review.
Mediastinum
December 2024
Department of Respiratory Medicine, NHO Nagoya Medical Center, Nagoya, Japan.
Background And Objective: Transesophageal endosonography, including endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and endoscopic ultrasound with bronchoscope-guided fine-needle aspiration (EUS-B-FNA), has been applied to the diagnosis of benign as well as malignant diseases. This narrative review summarizes the recent use of EUS-(B)-FNA in diagnosing sarcoidosis.
Methods: A comprehensive and systematic online literature search of PubMed was conducted using the keywords ("sarcoidosis"), and ("EUS" OR "EUS-FNA" OR "EUS-B" OR "EUS-B-FNA" OR "endoscopic ultrasound guided fine needle aspiration" OR "endoscopic ultrasound using the EBUS scope guided fine needle aspiration" OR "endoscopic ultrasound using the EBUS bronchoscope" OR "transesophageal" OR "transesophageal endoscopic ultrasound guided fine needle aspiration" OR "transesophageal bronchoscopic ultrasound guided fine needle aspiration").

Suraxavir marboxil (GP681) is an antiviral drug inhibiting the polymerase acidic protein (PA) of RNA polymerase, of influenza. It has shown therapeutic activity against influenza A and B virus infections in preclinical studies. In this multicenter randomized, double-blind, placebo-controlled, phase 3 trial, we aimed to investigate the efficacy and safety of single-dose suraxavir marboxil (40-mg oral dose) in otherwise healthy outpatients aged 5-65 years with uncomplicated influenza unaccompanied by severe issues.

In this study, we introduce a novel approach that integrates interpretability techniques from both traditional machine learning (ML) and deep neural networks (DNN) to quantify feature importance using global and local interpretation methods. Our method bridges the gap between interpretable ML models and powerful deep learning (DL) architectures, providing comprehensive insights into the key drivers behind model predictions, especially in detecting outliers within medical data. We applied this method to analyze COVID-19 pandemic data from 2020, yielding intriguing insights.

The SARS-CoV-2 pandemic significantly affected the epidemiology of , a pathogen associated with various clinical presentations such as pharyngitis, scarlet fever, and invasive diseases. This study analyzed the incidence and characteristics of infections between 2018 and 2023, examining 915 cases categorized as either respiratory or non-respiratory. Respiratory infections predominantly affected children, accounting for 76% of cases, with a median age of 5 [3, 8] years, while non-respiratory infections were more common in adults, with a median age of 46.
