Development of Progressively Earth-Independent Medical Operations to Enable NASA Exploration Missions.

-The National Aeronautics and Space Administration's (NASA's) transition from operations in low-Earth orbit to long-duration missions to the Moon and Mars necessitates the development of progressively Earth-independent medical operations (EIMO) to support crews and reduce overall mission risk. Previous work has defined and laid the foundation for EIMO, but further development of the concept is required to prepare for future exploration missions. -NASA's Exploration Medical Capability element organized a series of 5 technical interchange meetings from 2023 to 2024, which included internal (NASA) and external subject-matter experts in human spaceflight, health technology, and austere medicine to create a framework for developing the technologies and procedures necessary to maintain human health and performance in a progressively Earth-independent fashion.

Enabling Human Space Exploration Missions Through Progressively Earth Independent Medical Operations (EIMO).

Current Space Medicine operations depend on terrestrial support to manage medical events. As astronauts travel to destinations such as the Moon, Mars, and beyond, distance will substantially limit this support and require increasing medical autonomy from the crew. This paper defines Earth Independent Medical Operations (EIMO) and identifies key elements of a conceptual EIMO system.

The Wilderness Medical Society convened a panel to review the literature and develop evidence-based clinical practice guidelines on the treatment of anaphylaxis, with an emphasis on a field-based perspective. The review also included literature regarding the definition, epidemiology, clinical manifestations, and prevention of anaphylaxis. The increasing prevalence of food allergies in the United States raises concern for a corresponding rise in the incidence of anaphylaxis.

Associations Between Wildfire-Related PM and Intensive Care Unit Admissions in the United States, 2006-2015.

Wildfire smoke is a growing public health concern in the United States. Numerous studies have documented associations between ambient smoke exposure and severe patient outcomes for single-fire seasons or limited geographic regions. However, there are few national-scale health studies of wildfire smoke in the United States, few studies investigating Intensive Care Unit (ICU) admissions as an outcome, and few specifically framed around hospital operations.

Evidence-Based Heatstroke Management in the Emergency Department.

Introduction: Climate change is causing an increase in the frequency and intensity of extreme heat events, which disproportionately impact the health of vulnerable populations. Heatstroke, the most serious heat-related illness, is a medical emergency that causes multiorgan failure and death without intervention. Rapid recognition and aggressive early treatment are essential to reduce morbidity and mortality.

Training Clinical And Public Health Leaders In Climate And Health.

The effects of climate change are accelerating and undermining human health and well-being in many different ways. There is no doubt that the health care sector will need to adapt, and although it has begun to develop more targeted strategies to address climate-related challenges, a broad knowledge gap persists. There is a critical need to develop and cultivate new knowledge and skill sets among health professionals, including those in public health, environmental science, policy, and communication roles.

Clinical Implications of Climate Change on US Emergency Medicine: Challenges and Opportunities.

The adverse influences of climate change are manifesting as health burdens relevant to clinical practice, affecting the very underpinnings of health and stressing the health care system. Emergency medicine is likely to bear a large burden, with its focus on urgent and emergency care, through its role as a safety-net provider for vulnerable populations and as a leader in disaster medicine. Clinically, climate change is affecting emergency medicine practice through the amplification of climate-related disease patterns and epidemiologic shifts for conditions diagnosed and treated in emergency departments (EDs), especially for vulnerable populations.

The Climate-Smart Emergency Department: A Primer.

Climate change and environmental pollution from health care present urgent, complex challenges. The US health care sector produces 10% of total US greenhouse gas emissions, which have negative influences on human and environmental health. The emergency department (ED) is an important place in the hospital to become more environmentally responsible and "climate smart," a term referring to the combination of low-carbon and resilient health care strategies.

Science Policy Training for a New Physician Leader: Description and Framework of a Novel Climate and Health Science Policy Fellowship.

The accelerating health impacts of climate change are undermining global health, and the roles of the health sector in addressing the many challenges of climate change are being articulated by governments, multilateral institutions, and professional societies. Given the paucity of physician engagement on this issue to date, there now exists a clear need for health professionals to meet this new challenge with the development and cultivation of new knowledge and skill sets in public health, environmental science, policy, and communication. We describe a novel GME fellowship in climate and health science policy, designed to train a new generation of clinicians to provide the necessary perspective and skills for effective leadership in this field.

Climate Change and the Kidney.

The worldwide increase in temperature has resulted in a marked increase in heat waves (heat extremes) that carries a markedly increased risk for morbidity and mortality. The kidney has a unique role not only in protecting the host from heat and dehydration but also is an important site of heat-associated disease. Here we review the potential impact of global warming and heat extremes on kidney diseases.

Psychological Care Augmented by Telemedicine after a Polar Bear Encounter at an Arctic Research Station: A Case Report.

Psychologically stressful events can be particularly challenging in the wilderness or extreme environments due to a lack of immediate medical or psychological support. Telemedicine consultations may provide a means to supply medical providers in austere environments with expertise when confronted with these situations. In this study, we detail a case of psychological care imparted to residents at a remote, arctic research station after they encountered a polar bear.

Climate change has led to significant rise of 0.8°C-0.9°C in global mean temperature over the last century and has been linked with significant increases in the frequency and severity of heat waves (extreme heat events).

Wilderness Preparticipation Evaluation and Considerations for Special Populations.

Children, older adults, disabled and special needs athletes, and female athletes who participate in outdoor and wilderness sports and activities each face unique risks. For children and adolescents traveling to high altitude, the preparticipation physical evaluation should focus on risk assessment, prevention strategies, early recognition of altitude-related symptoms, management plans, and appropriate follow-up. As the risk and prevalence of chronic disease increases with age, both older patients and providers need to be aware of disease and medication-specific risks relative to wilderness sport and activity participation.
