Comparing the Effect of Acute Moderate and Vigorous Exercise on Inflammation in Adults with Asthma: A Randomized Controlled Trial.

Ann Am Thorac Soc 2022 Jul 8. Epub 2022 Jul 8.

The University of Queensland, 1974, Lung and Allergy Research Centre, Diamantina Institute, Brisbane, Queensland, Australia.

Rationale: Exercise is associated with improvements in asthma, however the mechanisms responsible are not clear. Exercise induces changes in systemic inflammation, and it is possible that these inflammatory effects extend to the airways of people with asthma. Studies in healthy adults suggest inflammatory responses are dependent on exercise intensity: while acute moderate exercise is anti-inflammatory, acute vigorous exercise appears to be neutral or pro-inflammatory.

Epinephrine evokes shortening of human airway smooth muscle cells following β adrenergic receptor desensitization.

Am J Physiol Lung Cell Mol Physiol 2022 08 5;323(2):L142-L151. Epub 2022 Jul 5.

Rutgers Institute for Translational Medicine and Science, Rutgers, The State University of New Jersey, New Brunswick, New Jersey.

Epinephrine (EPI), an endogenous catecholamine involved in the body's fight-or-flight responses to stress, activates α-adrenergic receptors (αARs) expressed on various organs to evoke a wide range of physiological functions, including vasoconstriction. In the smooth muscle of human bronchi, however, the functional role of EPI on αARs remains controversial. Classically, evidence suggests that EPI promotes bronchodilation by stimulating β-adrenergic receptors (βARs). Read More

Cut-off value for exercise-induced bronchoconstriction based on the features of the airway obstruction.

PLoS One 2022 26;17(5):e0268969. Epub 2022 May 26.

Division of Allergy, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.

The current cut-off value for diagnosing exercise-induced bronchoconstriction (EIB) in adults-percent fall in FEV1 (ΔFEV1) ≥ 10% after exercise challenge test (ECT)-has low specificity and weak evidences. Therefore, this study aimed to identify the cut-off value for EIB that provides the highest diagnostic sensitivity and specificity. Participants who underwent the ECT between 2007 and 2018 were categorized according to ΔFEV1: definite EIB (ΔFEV1 ≥ 15%), borderline (10% ≤ ΔFEV1 < 15%), and normal (ΔFEV1 < 10%). Read More

COVID-19 symptoms are reduced by targeted hydration of the nose, larynx and trachea.

Sci Rep 2022 03 29;12(1):4599. Epub 2022 Mar 29.

Sensory Cloud, 650 East Kendall St, Cambridge, MA, USA.

Dehydration of the upper airways increases risks of respiratory diseases from COVID-19 to asthma and COPD. We find in human volunteer studies involving 464 human subjects in Germany, the US, and India that respiratory droplet generation increases by up to 4 orders of magnitude in dehydration-associated states of advanced age (n = 357), elevated BMI-age (n = 148), strenuous exercise (n = 20) and SARS-CoV-2 infection (n = 87), and falls with hydration of the nose, larynx and trachea by calcium-rich hypertonic salts. We also find in a protocol of exercise-induced airway dehydration that hydration of the airways by calcium-rich salts increases oxygenation relative to a non-treatment control (P < 0. Read More

Is airway damage during physical exercise related to airway dehydration? Inputs from a computational model.

J Appl Physiol (1985) 2022 04 24;132(4):1031-1040. Epub 2022 Feb 24.

Laboratoire J. A. Dieudonné, UMR CNRS 7351, Université Côte d'Azur, Nice, France.

In healthy subjects, at low minute ventilation (V̇e) during physical exercise, the water content and temperature of the airways are well regulated. However, with the increase in V̇e, the bronchial mucosa becomes dehydrated and epithelial damage occurs. Our goal was to demonstrate the correspondence between the ventilatory threshold inducing epithelial damage, measured experimentally, and the dehydration threshold, estimated numerically. Read More
