AI Article Synopsis
- - The study investigated the impact of meal consumption on respiratory status in patients with acute pneumonia, particularly aspiration pneumonia, by monitoring their oxygen saturation (SpO) and pulse rate (PR).
- - 44 inpatients were divided into pneumonia and control groups; measurements were taken before, during, and after meals, revealing a significant drop in oxygen saturation during meals for the pneumonia patients.
- - Findings indicate that pneumonia can worsen respiratory function during meals, potentially affecting patients' ability to eat well; monitoring respiratory status during meals is crucial for these patients.
Article Abstract
Objective: This study aimed to investigate how respiratory status may be affected during meal consumption in patients with acute pneumonia, mainly aspiration pneumonia, using percutaneous oxygen saturation (SpO) and pulse rate (PR) measurements.
Methods: We recruited 44 inpatients at the Towada City Hospital and divided them into 'pneumonia' and 'control' groups. Generalized linear mixed effects model was used for analysis. The pneumonia group comprised 22 patients (mean age 81.2 ± 7.0 years, body mass index [BMI] 21.1 ± 4.0 kg/m) with 1-3 points A-DROP scores. The control group comprised 22 patients (mean age 80.5 ± 4.9 years, BMI 20.9 ± 2.9 kg/m) with no obvious respiratory diseases. SpO and PR were measured 30 min before, during, and 30 min after meals.
Results: SpO was significantly lower during meals in the pneumonia group (-1.60%; 95% confidence interval = -2.76 to -0.44). There were no significant changes in PR during or after meals in the pneumonia group.
Conclusions: This study suggests pneumonia may worsen respiratory status during meal intake. Patients with pneumonia may be unable to eat adequately due to worsened oxygenation during meals, even in the absence of aspiration. Therefore, it is important to observe whether there is a decrease in respiratory status during meals.

In patients with cystic fibrosis (CF), repeated cycles of infection and inflammation eventually lead to fatal lung damage. Although diminished mucus clearance can be restored by highly effective CFTR modulator therapy, inflammation and infection often persist. To elucidate the role of the innate immune system in CF etiology, we investigated a CF pig model and compared these results with those for preschool children with CF.

Apolipoprotein E (ApoE), especially the ApoE4 isotype, is suggested to influence the severity of respiratory viral infections; however, this association is still unclear. The presence of allele ε4 impacts the development of flu-like syndromes. This study aimed to evaluate the impact of the Apo E4 isoform on the severity and duration of flu-like syndromes, including the coronavirus disease COVID-19.

Background: After-hours pediatric anesthesia may pose increased risks, with a heightened potential for sudden cardio-respiratory decline. While mortality rates are low in Australia and New Zealand, critical events and morbidity occur more frequently and present ongoing challenges. However, little is known about how trainees are supervised during these high-risk periods.

Objective: Research on the inequality of chronic respiratory disease (CRD) is limited, and the association between CRD and all-cause mortality is not well-established. Investigating the distribution of CRD and its associated mortality risks is essential for improving CRD conditions and developing targeted intervention measures. This study aimed to explore the relationship between inequalities in CRD and all-cause mortality in China.
