ABSTRACT

Space travel exposes astronauts to several environmental challenges, including microgravity and radiation exposure. To overcome these stressors, the body undergoes various adaptations such as cardiovascular deconditioning, fluid shifts, metabolic changes, and alterations in the state of the bone marrow. Another area of concern is the potential impact of these adaptations on erythrocyte and haemoglobin concentrations, which can lead to what is commonly referred to as space anaemia or microgravity-induced anaemia. It is known that anaemia may result in impaired physical and cognitive performance, making early detection and management crucial for the health and wellbeing of astronauts during extended space missions. However, the effects and mechanisms of space anaemia are not fully understood, and research is underway to determine the extent to which it poses a challenge to astronauts. Further research is needed to clarify the long-term effects of microgravity on the circulatory system and to investigate possible solutions to address spaceflight-induced anaemia. This article reviews the potential link between spaceflight and anaemia, based on existing evidence from simulated studies (e.g., microgravity and radiation studies) and findings from spaceflight studies (e.g., International Space Station and space shuttle missions).

ABSTRACT

Institutional Research Ethics Committees (RECs) play crucial roles in the impartial and competent review of scientific research, particularly during public health emergencies. In this report, we examined their ability and capacity to provide this basic service during public health emergencies and non-emergency situations. Our qualitative documentary analysis revealed that there are currently no legal regulations guiding the activities of Kyrgyz RECs during public health emergencies. In addition, major policy gaps exist in how RECs should operate in non-emergency circumstances. This lack of guidance highlights the urgent need to develop and implement ethical guidelines to meet the evolving needs of such emergencies. Our findings underscore the growing urgency of supporting capacity building of RECs to respond effectively to future pandemics and other public health crises.
