The Impact of Heat-Not-Burn, E-Cigarettes, and Cigarettes on Small Airway Function.

Introduction: E-cigarettes and heated tobacco products (HTPs) are gaining worldwide significance. The tobacco industry is promoting these products as healthier alternatives to conventional cigarettes.

Methods: In this four-arm crossover study, we examined the acute effects of cigarette smoking, vaping IQOS, or vaping e-cigarettes (with or without nicotine) on hemodynamics, arterial stiffness, and small airways.

Impact of Chewing Bags, E-Cigarettes, and Combustible Cigarettes on Arterial Stiffness and Small Airway Function in Healthy Students.

Several substitute products are discussed as a healthier alternative to smoking, thereunder e-cigarettes and smokeless tobacco products, e.g., chewing bags, which are increasingly used in this context.

Use and Outcomes of Noninvasive Ventilation for Acute Respiratory Failure in Different Age Groups.

Background: The prevalence of chronic disease and do-not-intubate status increases with age. Thus, we aimed to determine characteristics and outcomes associated with noninvasive ventilation (NIV) use for acute respiratory failure (ARF) in different age groups.

Methods: A database comprising prospective data collected on site on all adult patients with ARF requiring ventilatory support from 8 acute care hospitals in Massachusetts was used.

Where is Noninvasive Ventilation Actually Delivered for Acute Respiratory Failure?

Purpose: Few studies have examined locations of noninvasive ventilation (NIV) application for acute respiratory failure (ARF). We aimed to track actual locations of NIV delivery and related outcomes.

Methods: Observational cohort study based at 8 acute care hospitals in Massachusetts on adult patients admitted for ARF requiring ventilatory support during pre-determined time intervals.

Use and outcomes of noninvasive positive pressure ventilation in acute care hospitals in Massachusetts.

Background: This study determined actual utilization rates and outcomes of noninvasive positive pressure ventilation (NIV) at selected hospitals that had participated in a prior survey on NIV use.

Methods: This observational cohort study, based at eight acute care hospitals in Massachusetts, focused on all adult patients requiring ventilatory support for acute respiratory failure during predetermined time intervals.

Results: Of 548 ventilator starts, 337 (61.
