AI Article Synopsis
- A study compared hospital outcomes between critically ill patients with COVID-19 and those with influenza A, focusing on mortality rates and risk factors.
- The research involved a retrospective analysis of adult patients in Hong Kong, matching 373 COVID-19 patients with 373 influenza A patients based on similar characteristics.
- Findings showed that COVID-19 patients had a significantly higher hospital mortality rate (17.5%) compared to influenza A patients (7.5%), with factors such as age and coinfections impacting these outcomes.
Article Abstract
Objectives: Direct comparisons between COVID-19 and influenza A in the critical care setting are limited. The objective of this study was to compare their outcomes and identify risk factors for hospital mortality.
Design And Setting: This was a territory-wide, retrospective study on all adult (≥18 years old) patients admitted to public hospital intensive care units in Hong Kong. We compared COVID-19 patients admitted between 27 January 2020 and 26 January 2021 with a propensity-matched historical cohort of influenza A patients admitted between 27 January 2015 and 26 January 2020. We reported outcomes of hospital mortality and time to death or discharge. Multivariate analysis using Poisson regression and relative risk (RR) was used to identify risk factors for hospital mortality.
Results: After propensity matching, 373 COVID-19 and 373 influenza A patients were evenly matched for baseline characteristics. COVID-19 patients had higher unadjusted hospital mortality than influenza A patients (17.5% vs 7.5%, p<0.001). The Acute Physiology and Chronic Health Evaluation IV (APACHE IV) adjusted standardised mortality ratio was also higher for COVID-19 than influenza A patients ((0.79 (95% CI 0.61 to 1.00) vs 0.42 (95% CI 0.28 to 0.60)), p<0.001). Adjusting for age, PO/FO, Charlson Comorbidity Index and APACHE IV, COVID-19 (adjusted RR 2.26 (95% CI 1.52 to 3.36)) and early bacterial-viral coinfection (adjusted RR 1.66 (95% CI 1.17 to 2.37)) were directly associated with hospital mortality.
Conclusions: Critically ill patients with COVID-19 had substantially higher hospital mortality when compared with propensity-matched patients with influenza A.

Background: Traumatic cervical spinal cord injury (cSCI) is a serious condition that requires a multidisciplinary treatment approach involving care at a neurotrauma center (NTC) and specialized rehabilitation. Contemporary population-based studies of cSCI are important for ensuring the quality and planning of health care approaches for these patients.
Methods: This is a population-based cohort study of patients with traumatic cSCI who were admitted to the NTC in Southeast Norway between 2015 and 2022.

Background And Objectives: Nosocomial pneumonia caused by multidrug-resistant gram-negative bacteria presents a significant challenge for healthcare systems, as there are limited effective treatments available. This systematic review and meta-analysis aim to investigate the outcomes of colistin plus meropenem combination therapy on nosocomial pneumonia.
Materials And Methods: An exhaustive search of PubMed, Scopus, Web of Science (WOS), and Embase databases was conducted, resulting in the extraction of 5 studies for qualitative assessment and meta-analysis.

Lymphangiomas are localized multi-cystic malformations of the lymphatic and vascular system, primarily affecting the head and neck regions in children. Orbital lymphangiomas are not considered hamartomas because the orbit does not commonly display lymphatic vessels. In this case report, we describe a male patient who was 15 years old and presented to our medical facility with the primary complaints of having a bulging left eye, sudden chemosis of the lower conjunctiva, and pain in the left eye.
