In October and November 2023, hospitals in the major cities of Beijing and Liaoning in northern China reported a surge in cases of pneumonia in children, with some hospitals being overwhelmed by pediatric emergency admissions. Similar outbreaks of childhood pneumonia had been reported in the autumn of 2022 in Europe and North America. Therefore, increased reports of childhood pneumonia could be driven by post-pandemic changes in the pathogenesis of endemic respiratory infections other than COVID-19, including Mycoplasma pneumoniae, respiratory syncytial virus (RSV), and influenza, rather than emerging novel pathogens. However, the recent reports of increased hospitalizations for children with pneumonia warrant continued infection surveillance and monitoring to exclude new respiratory pathogens or more virulent variants of known pathogens, including SARS-CoV-2. This editorial aims to present what is known about the re-emergence of endemic respiratory infections, which may be the cause of the recently reported outbreaks of childhood pneumonia.

A Global Collaborative Comparison of SARS-CoV-2 Antigenicity Across 15 Laboratories.

Setting up a global SARS-CoV-2 surveillance system requires an understanding of how virus isolation and propagation practices, use of animal or human sera, and different neutralisation assay platforms influence assessment of SARS-CoV-2 antigenicity. In this study, with the contribution of 15 independent laboratories across all WHO regions, we carried out a controlled analysis of neutralisation assay platforms using the first WHO International Standard for antibodies to SARS-CoV-2 variants of concern (source: NIBSC). Live virus isolates (source: WHO BioHub or individual labs) or spike plasmids (individual labs) for pseudovirus production were used to perform neutralisation assays using the same serum panels.

Importance: A high infection burden in early childhood is common and a risk factor for later disease development. However, longitudinal birth cohort studies investigating early-life infection burden and later risk of infection and antibiotic episodes are lacking.
Objective: To investigate whether early-life infection burden is associated with a later risk of infection and systemic antibiotic treatment episodes in childhood.
Severe mycoplasma pneumoniae pneumonia combined with cold agglutinin disease and pulmonary embolism in childhood: A case report and review of the literature.

Department of Pediatrics, The Affiliated Yantai Yuhuangding Hospital of Qingdao University, Yantai 264000, Shandong, China.
This was a case report and literature review, aimed to strengthen the understanding and therapy of mycoplasma pneumoniae (MP) pneumonia combined with cold agglutinin disease and pulmonary embolism in children. A 7-year-old boy was taken to the hospital with fever for 7 days, cough for 5 days, and recurrent cyanosis at the extremities of one day duration. Pulmonary artery computed tomography angiography (CTA) showed pulmonary embolism, double pneumonia, and pleural effusion.

Introduction: The government's role in influencing policies related to Coronavirus disease 2019 (COVID-19) vaccine distribution and handwashing practices is essential in controlling the spread of severe acute respiratory syndrome coronavirus 2.
Methods: This study aimed to systematically review published studies to explore the influence of government policies on handwashing and vaccine uptake in Kenya, Uganda and Tanzania to prevent and control COVID-19. A comprehensive search strategy was applied across three databases, and eligibility was determined using strict inclusion and exclusion criteria.
Six Versus Three Doses of Intrapleural Streptokinase in Childhood Empyema: A Randomized Controlled Trial.

Department of Pediatric Surgery, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.
Objective: To compare the efficacy and safety of administering six doses of intrapleural streptokinase (SK) versus the conventional three doses, in children with empyema.
Study Design: In this open label, placebo-controlled, randomized trial, we enrolled 53 children with empyema, who received three doses of intrapleural SK. Thereafter, those without clinical improvement (n = 34) and those showing clinical improvement but having persistent pleural fluid width > 10 mm on chest ultrasonography (n = 13), were randomized to receive three additional doses of SK, or three doses of placebo (normal saline).
