Objective: To characterize pulse oxygen saturation (SpO) trajectories and respiratory interventions after birth for newborns with cyanotic congenital heart disease (CCHD).
Study Design: Retrospective single-site study of newborns ≥32 weeks gestation with CCHD: single ventricle with critical aortic obstruction (SV-CAO), critical pulmonic obstruction (CPO), transposition of the great arteries (TGA). Minute-to-minute SpO values and respiratory interventions were summarized and compared.
Results: Two hundred infants were enrolled. SpO at each minute differed across groups (p < 0.01), with the lowest values in TGA. All interventions were most frequent in TGA (p < 0.01). Continuous positive airway pressure was provided in 22% SV-CAO, 23% CPO, and 66% TGA. Positive pressure ventilation occurred in 7% SV-CAO, 14% CPO, and 33% TGA. Intubation occurred in 4% SV-CAO, 10% CPO, and 53% TGA.
Conclusion: We defined SpO trajectories and delivery room respiratory interventions for three CCHD phenotypes. These results inform delivery room management of these high-risk populations.

Objectives: To describe changes in the volume and types of emergency medical services (EMS) calls for children during the COVID-19 pandemic and after availability of the COVID-19 vaccine ("reopening period").
Methods: A retrospective cross-sectional study of EMS 9-1-1 responses to children under 18 years for all causes over a 4-year period (2019-2022) reported in the National Emergency Medical Services Information System (NEMSIS) dataset. Data was stratified into three periods, Pre-pandemic, Pandemic and Reopening.

The ICH E9 addendum on estimands in clinical trials provides a framework for precisely defining the treatment effect that is to be estimated, but says little about estimation methods. Here, we report analyses of a clinical trial in type 2 diabetes, targeting the effects of randomized treatment, handling rescue treatment and discontinuation of randomized treatment using the so-called hypothetical strategy. We show how this can be estimated using mixed models for repeated measures, multiple imputation, inverse probability of treatment weighting, G-formula, and G-estimation.

Methods: A multicenter retrospective cohort study included adult patients with laboratory-confirmed babesiosis from 2009 to 2023.
A Non-invasive Lung Disease Study of Exhaled Breath Nitric Oxide Based on Ultraviolet Differential Absorption Spectroscopy Techniques.

Clinical Research Center for Respiratory Disease (Tumor) in Anhui Province, Bengbu, Anhui Province, China.
In this study, a non-invasive device based on ultraviolet differential absorption spectroscopy (UV-DOAS) technology for detecting fractional exhaled nitric oxide (FeNO)was developed and clinically validated in patients with various lung diseases. The diagnostic potential of FeNO was explored by analysing subgroups of patients with lung cancer, nodules, and other disease. The results showed that FeNO concentrations were significantly higher in patients with malignant tumours than in healthy controls (p < 0.

Background/purpose: One of the causes of ventilator-associated pneumonia (VAP) is aspiration of oropharyngeal fluid containing pathogenic microorganisms into the lower respiratory tract. In this study, we aimed to investigate whether antibiotic ointment applied to the oral cavity can reduce the number of bacteria in the fluid on the cuff of a tracheal cannula.
Materials And Methods: Tetracycline ointment was applied intraorally once to a patient under endotracheal intubation by postoperative tracheostomy for oral cancer.
