Neuro-ophthalmological changes have been reported after prolonged exposure to microgravity; however, the pathophysiology remains unclear. Furthermore, several countermeasures have been suggested to counteract the side effects of microgravity. The objectives of the present study were twofold: (1) to assess the neuro-ophthalmological impact of 60 day...

Neuro-ophthalmological changes named spaceflight associated neuro-ocular syndrome (SANS) reported after spaceflights are important medical issues. Dry immersion (DI), an analog to microgravity, rapidly induces a centralization of body fluids, immobilization, and hypokinesia similar to that observed during spaceflight. The main objectives of the pre...

Space agencies use terrestrial-based analog missions to reduce risk and cost of spaceflight operations. This paper explains how research simulations differ from more traditional spaceflight analogs, and describes medical mishaps that may occur. Suggested paths to improved safety standards will better prepare health and safety officers to address he...

COVID-19 and the related quarantine disrupted young adults' academic and professional life, daily routine and socio-emotional well-being. This cross-sectional study focused on the emotional and behavioural responses of a young adult population during the COVID-19-related quarantine in April 2020, in Greece. The study was conducted through an online...

Objective Fear of COVID-19 was associated with more severe depressive and anxiety symptoms. This study aimed to explore COVID-19-related fear, depressive and anxiety symptoms, social responsibility, and behavioral responses during the COVID-19 pandemic in Greece. Method A cross-sectional study was conducted from April 10 to April 13, 2020. Members...

As exciting as analog space missions can be, contributing towards the progression and development of human space exploration, whilst we are still on earth, as medical professionals we are duty bound to provide an appropriate and adequate level of care to those participating. As well as protecting ourselves and supporting each other in providing suc...

The objective of this study was to investigate depth perception in astronauts during and after spaceflight by studying their sensitivity to reversible perspective figures in which two-dimensional images could elicit two possible depth representations. Other ambiguous figures that did not give rise to a perception of illusory depth were used as cont...

This paper deals with a special area of cognitive infocommunications, in which the goal is to determine the cogni-tive state of subjects through the measurement of speech parame-ters. Human speech is a complex function that consists of cogni-tive and organic relationships. The state of the brain regions responsible for producing speech has a great...

As space programs mature, international cooperation is enhanced and new private players step into the space sector, there seems to be an upcoming shift from short-term human missions to longer ones. Ultimately reaching Mars is globally perceived as the next great leap-but who will be those to eventually step on the Red Planet? The medical and psych...

In an era of technological advancement, with space programs becoming more mature and focused and new players coming in the space sector, the time draws near for humanity to venture forth in exploration of the solar system once again. Reaching Mars is internationally perceived as the next great leap – but who will be those to eventually go? Astrona...

It is important for the advancement of the human species to leave the cradle of Earth and extend human presence to the rest of the Solar System and beyond. The Mars-X project identifies the problems associated with sending humans to a Martian moon and returning them safely to Earth. A framework is suggested for addressing these challenges by propos...
