Epidemiological and Clinical Characteristics of Neonatal Infection.

Purpose: To understand the epidemiology and clinical features of (UU) infection in hospitalized neonates due to vertical transmission from mother to child.

Methods: Respiratory secretions were collected from neonates hospitalized in the neonatology department of the Maternal and Child Health Hospital of Hubei Province from July 2020 to June 2022, and PCR was used to detect UU-DNA in respiratory secretions. The neonates were divided into UU-positive and UU-negative groups, the epidemiological and clinical characteristics of two groups, were statistically analyzed.

β-Glucan Induces Training Immunity to Promote Antiviral Activity by Activating TBK1.

Many studies have shown that β-glucan induces a trained immune phenotype in innate immune cells to defend against bacterial and fungal infections. The specific mechanism involves cellular metabolism and epigenetic reprogramming. However, it is unclear whether β-glucan plays a role in antiviral infection.

Senotherapeutics: An emerging approach to the treatment of viral infectious diseases in the elderly.

In the context of the global COVID-19 pandemic, the phenomenon that the elderly have higher morbidity and mortality is of great concern. Existing evidence suggests that senescence and viral infection interact with each other. Viral infection can lead to the aggravation of senescence through multiple pathways, while virus-induced senescence combined with existing senescence in the elderly aggravates the severity of viral infections and promotes excessive age-related inflammation and multiple organ damage or dysfunction, ultimately resulting in higher mortality.

[Comparative study on application of Duo positive airway pressure and continuous positive airway pressure in preterm neonates with respiratory distress syndrome].

Objective: To determine whether early application of Duo positive airway pressure (DuoPAP), in comparison with nasal continuous positive airway pressure (NCPAP), can reduce the need for endotracheal intubation and mechanical ventilation and decrease the incidence of bronchopulmonary dysplasia (BPD) in preterm neonates with respiratory distress syndrome (RDS).

Methods: In a single-center, randomized controlled trial, preterm neonates (gestational ages 30-35 weeks) with RDS were randomly assigned to receive DuoPAP (n=34) or NCPAP (n=33) within 6 hours of birth. If the two noninvasive ventilations were not effective, endotracheal intubation and mechanical ventilation were used, and pulmonary surfactant was administered as rescue therapy.
