In paediatric patients, β-lactams and macrolides are widely used to treat acute otitis media and sinusitis, which are often caused by either Streptococcus pneumoniae or Haemophilus influenzae. However, resistant isolates have emerged and are becoming more prevalent. H. influenzae generally acquires antimicrobial resistance by mutation or by expression of β-lactamase. In this study, we isolated H. influenzae from a paediatric patient diagnosed with acute sinusitis. This strain harboured multiple exogenous resistance genes: bla, mef(A) and tet(M). DNA sequencing suggested that both mef(A) and tet(M) had been transferred from S. pneumoniae or another Streptococcus. This typical outpatient had not been exposed to excessive levels of antibiotics and had no underlying diseases, strongly suggesting that this type of resistant isolate could become more prevalent.

Association of gross domestic product with equitable access to childhood vaccines in 195 countries: a systematic review and meta-analysis.
BMJ Glob Health
January 2025
African Vaccinology Network, Buea, Cameroon.
Introduction: Gross domestic product (GDP) has been shown to affect government spending on various budget heads including healthcare and the purchase and distribution of vaccines. This vulnerable situation has been exacerbated by the COVID-19 pandemic which disrupted and exposed the fragile nature of equitable access to vaccines for childhood immunisation globally. A systematic review and meta-analysis to assess the association of country income status and GDP with vaccination coverage of vaccines for childhood immunisation and other major infectious diseases around the globe will inform global and national policy on equity in living standards and vaccine uptake.

Background: Polymicrobial pneumonia is a concern for clinicians due to its association with increased disease severity. Determining the prevalence of polymicrobial pneumonia and identifying patients who have an increased risk of this aetiology is important for the management of CAP patients. Here we describe the clinical characteristics and outcomes of adult hospitalized patients with CAP, and identify the risk factors related to polymicrobial pneumonia and specifically to 30-day mortality.

Background: The primary purpose of this study was to detect the pathogen species using targeted next-generation sequencing (tNGS) to investigate the characteristics of community-acquired pneumonia (CAP)-related pathogens in children in Xiantao city, Hubei province, China.
Methods: A total of 1,527 children with CAP were prospectively recruited from our hospital between May 2022 and February 2023. Information on age and sex was collected from the medical records.
Synthesis of Pyrazole-Based Inhibitors of the Bacterial Enzyme -Succinyl-l,l-2,6-Diaminopimelic Acid Desuccinylase (DapE) as Potential Antibiotics.

Based on the inhibitory potencies from earlier reported tetrazole thioether analogs, we now describe the synthesis and inhibition of pyrazole-based inhibitors of -succinyl-l,l-2,6-diaminopimelic acid desuccinylase (DapE) from (DapE). The most potent pyrazole analog bears an aminopyridine amide with an IC of 17.9 ± 8.

Department of Pediatrics, Fu Yang People's Hospital, Fuyang, China.
Background: The COVID-19 pandemic has significantly altered the etiological spectrum and epidemiological characteristics of pediatric respiratory diseases, and a profound understanding of these changes is crucial for guiding clinical treatment. The purpose of this study is to analyze the etiological patterns and epidemiological features of pathogens in bronchoalveolar lavage fluid (BALF) from children with pediatric lower respiratory tract infections (LRTIs) after the COVID-19 pandemic, with the aim of providing effective therapeutic evidence for clinical practice.
Methods: This study enrolled pediatric patients diagnosed with LRTIs who were treated and underwent BALF pathogen detection at our hospital from June 1, 2023, to June 1, 2024.
