Characteristics of In-Flight Medical Emergencies on a Commercial Airline in Mainland China: Retrospective Study.
JMIR Public Health Surveill
December 2024
Shanghai Institute of Aviation Medicine, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Background: In-flight medical emergencies (IMEs) can have severe outcomes, including the deaths of passengers and aircraft diversions. Information is lacking regarding the incidence rate and characteristics of IMEs in most countries, especially in mainland China.
Objective: The objective of this study was to investigate the incidence, patterns, and associated risk factors of IMEs in mainland China and to provide medical suggestions for the evaluation and management of IMEs.
Different spectrum of space radiation induced cognitive impairments in radiation-naïve and adapted rats.
Life Sci Space Res (Amst)
November 2024
Radiation Oncology, USA.
Article Synopsis
- - NASA is planning to resume manned deep space missions, starting with the Moon and then Mars, and is investigating the potential health impacts of space radiation on astronauts during these long missions.
- - Research indicates that astronauts might experience significant impairments in cognitive functions, particularly in advanced executive skills, and these effects could vary based on their previous space exposure.
- - A study on rats found that after being re-exposed to space radiation, their ability to perform attentional set shifting tasks significantly declined, showing that prior radiation exposure alters cognitive impairments compared to animals that have never been exposed.
Can resting lung function predict the response of a person living with motor neuron disease to a hypoxic challenge test?
Amyotroph Lateral Scler Frontotemporal Degener
November 2024
Institute for Breathing and Sleep, Heidelberg, Australia.
Objective: People living with MND (PlwMND) are at risk of altitude-related hypoxia during flight. The Hypoxic Challenge Test (HCT) determines whether in-flight oxygen is required but can be expensive and inaccessible. To assist with travel recommendations, we investigated the relationship between altitude simulation-induced hypoxemia and baseline lung function.

International Sepsis Forum, Murphy, NC, USA.
Medical progress is reflected in the advance from broad clinical syndromes to mechanistically coherent diagnoses. By this metric, research in sepsis is far behind other areas of medicine-the word itself conflates multiple different disease mechanisms, whilst excluding noninfectious syndromes (e.g.

Celestial orientation and navigation are performed by many organisms in contexts as diverse as migration, nest finding and straight-line orientation. The vinegar fly, Drosophila melanogaster, performs menotaxis in response to celestial cues during tethered flight and can disperse more than 10 km under field conditions. However, we still do not understand how spectral components of celestial cues and pauses in flight impact heading direction in flies.
