Article Synopsis
- The study investigates the impact of exacerbations of Chronic Obstructive Pulmonary Disease (ECOPD) on global mortality and hospital readmission rates after hospitalization.
- The analysis included data from 65,945 COPD patients, revealing a 6.2% in-hospital mortality rate and significant post-discharge mortality and readmission rates at various intervals.
- Researchers emphasize the need for standardized management of ECOPD and suggest that policymakers prioritize funding for effective therapies to reduce the incidence of recurrent hospitalizations.
Background And Objective: High-flow nasal cannula (HFNC), a relatively new technique in acute hypoxemic respiratory failure (AHRF), is gaining popularity in intensive care units (ICUs). Our study aims to identify the predictive factors for failure of HFNC.
Materials And Methods: This is a 5-year retrospective cohort study in patients with AHRF using HFNC in an ICU of a regional hospital in Hong Kong.
Background: The real-world relationships between the demographic and clinical characteristics of asthma patients, their prehospitalization management and the frequency of hospitalization due to asthma exacerbation is poorly established.
Objective: To determine the risk factors of recurrent asthma exacerbations requiring hospitalizations and evaluate the standard of baseline asthma care.
Methods: A territory-wide, multicentre retrospective study in Hong Kong was performed.
We presented a case with massive hepatic portovenous gas (HPVG) and gastric emphysema, probably due to increased intraluminal pressure in the stomach after bagging and noninvasive ventilation. There are multiple microbubbles in the inferior vena cava, right atrium and right ventricle. There has been only one case report ever published showing the similar features of the "aquarium sign" in the right heart in a patient with intussusception.

However, the outcomes of AE-COPD patients with compensated respiratory acidosis are not known.
Methods: We performed a 1-year prospective, single-centre, cohort study in patients surviving the index admission for AE-COPD to compare baseline factors between groups with normocapnia, compensated respiratory acidosis and decompensated respiratory acidosis.
Background And Objective: Patients with chronic obstructive pulmonary disease (COPD) presenting with acute hypercapnic respiratory failure (AHcRF) benefit from non-invasive ventilation (NIV). The best way to withdraw NIV is not known, and we conducted a pilot study comparing stepwise versus immediate withdrawal of NIV in these patients.
Methods: This was a prospective, single-centre, open-labelled randomized study comparing stepwise versus immediate withdrawal of NIV in patients with COPD exacerbation recovering from AHcRF.
