Letter Randomized Controlled Trial
Non-invasive ventilatory support accelerates the oxygen uptake and heart rate kinetics and improves muscle oxygenation dynamics in COPD-HF patients.
The aim of this study was to explore the effects of non-invasive positive pressure ventilation (NIPPV) associated with high-intensity exercise on heart rate (HR) and oxygen uptake (V̇O2) recovery kinetics in in patients with coexistence of chronic obstructive pulmonary disease (COPD) and heart failure (HF). ⋯ NIPPV applied during high-intensity dynamic exercise can effectively improve exercise tolerance, accelerate HR and V̇O2 kinetics, improve respiratory and peripheral muscle oxygenation in COPD-HF patients. These beneficial results from the effects of NIPPV may provide evidence and a basis for high-intensity physical training for these patients in cardiopulmonary rehabilitation programs.

To evaluate the degree to which clinical comorbidities or combinations of comorbidities are associated with SARS-CoV-2 breakthrough infection. ⋯ Further measures should be taken to prevent breakthrough infection for individuals with these conditions, such as acquiring additional doses of the SARS-CoV-2 vaccine to boost immunity.

Meta Analysis
The Safety of Intravenous Peripheral Administration of 3% Hypertonic Saline: A Systematic Review and Meta-analysis.
Three percent hypertonic saline (3% HTS) is used to treat several critical conditions such as severe and symptomatic hyponatremia and increased intracranial pressure. It has been traditionally administered through a central venous catheter (CVC). The avoidance of peripheral intravenous infusion of 3% HTS stems theoretically from the concern about the ability of the peripheral veins to tolerate hyperosmolar infusions. The aim of this systematic review and meta-analysis is to assess the rate of complications associated with the infusion of 3% HTS using peripheral intravenous access. ⋯ Peripheral administration of 3% HTS is considered a safe and possibly preferred option as it carries a low risk of complications and is a less invasive procedure compared to CVC.
