Introduction: Endurance exercise at altitude can increase cardiac output and pulmonary vascular pressure to levels that may exceed the stress tolerability of the alveolar-capillary unit. This study examined the effect of ultramarathon trail racing at different altitudes (ranging from <1000 m to between 1500 and 2700 m) on alveolar-capillary recruitment and lung diffusion.
Methods: Cardiac and lung function were examined before and after an ultramarathon in 67 runners (age: 41 ± 9 yr, body mass index: 23 ± 2 kg·m -2 , 10 females), and following 12-24 h of recovery in a subset ( n = 27).
Article Synopsis
- The study examines ultrasound lung comet tails (B-lines), which are typically used to detect pulmonary edema, especially in heart failure patients, and their presence is often thought to indicate fluid accumulation in unhealthy individuals.
- Researchers found that during extreme physical activities like the Ultra Trail Mont Blanc race, healthy individuals exhibited an increased number of comet tails, prompting questions about the reliability of B-lines as an indicator of extravascular lung water in these circumstances.
- The authors suggest that B-lines may not always signify pathological conditions in healthy athletes, recommending a multi-faceted approach for assessing fluid levels in the lungs rather than solely relying on ultrasound findings.

Introduction: Neurodevelopmental disorders (NDD) affect 5 to 15% of the population. Improved management largely depends on early detection in primary care. A screening tool was developed by an expert consensus and its use has been recommended since 2019.

Information was sparingly given by the patient (an anesthetist) to several of his colleagues and no one was in charge to collect clinical data, take a history, and provide appropriate treatment. The combination of the absence of designation of a supervising doctor and the difficulty of communicating with the patient led to a lack of coordinated management and to an evolution of the symptoms towards severe acute mountain sickness.

- This study investigates the physiological responses of female ultramarathon runners, comparing them with male counterparts during and after a race.
- Data were collected from 53 ultramarathon participants, focusing on specific biomarkers and lung function measurements before and after racing.
- Results show that females had significant increases in certain biomarkers post-race, while males demonstrated greater reductions in lung capacity and evidence of mild pulmonary edema, indicating different physiological impacts between genders.
