Objective: To explore the association between hypochloremia and mortality in critically ill patients with chronic heart failure (CHF). Methods: This is a retrospective cohort study from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database of patients with CHF diagnosed according to ICD-9 or ICD-10. Patients were divided into three groups according to serum chloride values. A multivariable logistic regression analysis was used to investigate the relationship between hypochloremia and short-term mortality. Results: A total of 2103 patients with CHF were enrolled in our study. The 30-day mortality was 6.7%. After adjusting for confounders, the 30-day mortality risks of the hypochloremia group were significantly higher than that of the group with normal serum chloride (OR 2.23, 95% CI 1.27–3.92, p = 0.005). Hypochloremia was consistently associated with increased mortality in patients that were older or had sepsis. Conclusion: Hypochloremia is associated with increased mortality in intensive care patients critically ill with CHF.

BackgroundChlamydia psittaci is the causative agent of psittacosis in humans, while its rapid identification is hampered due to the lack of specificity of laboratory testing methods.Case presentationThis study reports four cases of C. psittaci infection after contact with a domestic parrot, all belonging to the same family. Common manifestations like fever, cough, headache, nausea, and hypodynamia appeared in the patients. Metagenomic next-generation sequencing (mNGS) aided the etiological diagnosis of psittacosis, revealing 58318 and 7 sequence reads corresponding to C. psittaci in two cases. The detected C. psittaci was typed as ST100001 in the Multilocus-sequence typing (MLST) system, a novel strain initially reported. Based on the results of pathogenic identification by mNGS, the four patients were individually, treated with different antibiotics, and discharged with favorable outcomes.ConclusionIn diagnosing psittacosis caused by a rare C. psittaci agent, mNGS provides rapid etiological identification, contributing to targeted antibiotic therapy and favorable outcomes. This study also reminds clinicians to raise awareness of psittacosis when encountering family members with a fever of unknown origin.

Objective • Assessing the safety and efficacy of enteral nutrition in critically ill patients receiving prone position ventilation is essential to optimize treatment strategies for critically ill patients. Systematically evaluate the effectiveness and safety of prone position enteral nutrition in critically ill ventilated patients, providing a reference for clinical decision-making. Methods • We conducted a comprehensive search for relevant studies on the safety and efficacy of enteral nutrition in prone ventilation patients. Our search encompassed randomized controlled trials, quasi-experimental studies, and cohort studies, utilizing databases including PubMed, Embase, and Scopus. The search duration spanned from May 2000 to May 2023. Inclusion and exclusion criteria were applied to select eligible literature, followed by data extraction and quality assessment. We employed specific keywords and filters in our search strategy to ensure a robust selection of studies. Subsequently, statistical analysis was performed utilizing RevMan 5.2 software to synthesize and interpret the findings effectively. Result • Five articles were ultimately included, with a total of 372 patients undergoing prone ventilation. The metaanalysis results showed that patients receiving enteral nutrition during prone and supine ventilation had higher levels of gastric residue incidence [RR = -0.01, 95% CI: (-0.08, 0.06), P = .77]. There was no significant difference in the incidence of vomiting/reflux between the prone position group and the control group [RR = 0.60, 95%CI: (0.15- 2.45), P = .48]. Prone position ventilation had no significant effect on the incidence of ventilator-associated pneumonia (VAP) [RR = 1.00, 95%CI: (0.14-6.90), P = 1.00]. There was no significant difference in the rate of enteral nutrition interruption between the prone position group and the control group [RR = 0.65, 95%CI: (0.28-1.52), P = .32]. Conclusion • Enteral nutrition in critically ill patients receiving prone position ventilation was not associated with high levels of gastric residual, vomiting or reflux, ventilator-associated pneumonia, or increased incidence of enteral nutrition interruption.

The use of Metagenomics Next-Generation Sequencing (mNGS) as a diagnostic tool for respiratory infections, particularly in the context of retired fitness players, presents a novel avenue for optimizing healthcare and wellness in this unique population. Respiratory illnesses, including influenza, can have profound effects on the health and performance of retired athletes, making accurate and timely diagnosis paramount. In this study, we aimed to assess the applicability of mNGS in diagnosing influenza virus infections in retired fitness players. We collected and analyzed respiratory samples from this specific cohort, leveraging mNGS technology. Our research focused on evaluating mNGS's potential as a diagnostic tool compared to conventional methods. Our findings underscored the remarkable capabilities of mNGS. When compared to traditional diagnostic techniques, mNGS demonstrated superior sensitivity in detecting influenza virus-positive respiratory samples in retired fitness players. Additionally, mNGS facilitated the identification of not only known influenza strains but also previously undetected viral variants, offering a comprehensive view of the viral landscape. The utilization of mNGS as a diagnostic tool in the care of retired fitness players holds great promise in enhancing their health monitoring and overall well-being. This technology can aid in the early detection and precise characterization of respiratory infections, contributing to the timely implementation of targeted interventions and improving the quality of healthcare for this unique and health-conscious population.
