Born high, born fast: Does highland birth confer a pulmonary advantage for sea level endurance?

Experimental Physiology, EarlyView.
Abstract Less than 7% of the world's population live at an altitude above 1500 m. Yet, as many as 67% of medalists in the 2020 men's and women's Olympic marathon, and 100% of medalists in the 2020 men's and women's Olympic 5000 m track race may have been born or raised above this otherwise rare threshold.

Diagnostic test interpretation and referral delay in patients with interstitial lung disease. [PDF]

, 2019
BACKGROUND:Diagnostic delays are common in patients with interstitial lung disease (ILD). A substantial percentage of patients experience a diagnostic delay in the primary care setting, but the factors underpinning this observation remain unclear.

Recommendations for the use of endoscopic lung volume reduction in South Africa: Role in the treatment of emphysema [PDF]

, 2015
Emphysema is a very common cause of morbidity and mortality in South Africa (SA). Therapeutic options in severe emphysema are limited. Endoscopic lung volume reduction (ELVR) is increasingly being used internationally for the treatment of advanced ...

The modified Borg cycle strength test (mBCST): Feasibility and physiological response in people with COPD and healthy older adults

Experimental Physiology, EarlyView.
Abstract Accurate prescription of supramaximal exercise requires exercise tests covering the intensity domain between maximal aerobic and peak power output. All‐out tests are commonly used for this objective but are considered challenging for people with chronic obstructive pulmonary disease (COPD) due to the extreme physiological demand.

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

Experimental Physiology, EarlyView.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

DLNO/DLCO ratio evolution under targeted therapy in patients with pulmonary hypertension

Respiratory Physiology & Neurobiology, 2020
The ratio of the diffusing capacity of the lung for carbon monoxide (DLCO) and for nitric oxide (DLNO) measured simultaneously is modified in patients with precapillary pulmonary hypertension (PH). The potential impact of targeted therapy on the DLCO/DLNO ratio is unknown. Simultaneous measurements of DLNO and DLCO were performed at baseline, 3-4 month

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

Experimental Physiology, EarlyView.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...
