Aerosol inhalation is considered the optimal route for administering the majority of drugs for the treatment of obstructive airways diseases. A number of Pressurised Metered-Dose and Dry Powder Inhalers are available for this purpose. However, inhalation of therapeutic aerosols is not without difficulty; it requires precise instructions on the inhalation manoeuvre, which is different from spontaneous normal breathing. Also, the characteristics of the inhaler device have to be suitable for the user. Available data indicate a frequent lack of knowledge demonstrated by health professionals and patients on the inhalation manoeuvre and handling of inhalers, resulting in a reduction of therapeutic benefit. This paper reviews the literature concerning the fundamental aspects of inhaler devices, inhalation manoeuvre and device selection, in an attempt to increase the knowledge of, and to optimise the clinical use of, therapeutic inhalers.

Hibernation and torpor are not passive responses caused by external temperature drops and fasting but are active brain functions that lower body temperature. A population of neurons in the preoptic area was recently identified as such active torpor-regulating neurons. We hypothesized that the other hypothermia-inducing maneuvers would also activate these neurons.

Hemorrhagic shock is a significant cause of trauma-related mortality. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less-invasive aortic occlusion maneuver for severe hemorrhagic shock but potentially inducing oxidative stress injuries. In an animal model, this study investigated hydrogen gas inhalation therapy's potential to mitigate post-REBOA ischemia-reperfusion injuries (IRIs).

Modeling aerosol dynamics in the airways is challenging, and most modern personalized tools consider only a single inhalation maneuver through less than 10% of the total lung volume. Here, we present an modeling pipeline to produce a device that preserves patient-specific upper airways while approximating deeper airways, capable of achieving total lung volumes over 7 liters. The modular system, called TIDAL, includes tunable inhalation and exhalation breathing capabilities with resting flow rates up to 30 liters per minute.

Background: Mechanical ventilation is a common and often lifesaving intervention that is utilised in intensive care. However, the practices can vary between centres. Through this national survey we aim to gain more information about different strategies adopted across the UK.
