Supplying a pharmacy for NASA Exploration SpaceFlight

Lunes, 24 de junio de 2019 Mar铆a Josep Mart铆 Utset Sin comentarios

In order to maintain crew health and performance during long-duration spaceflight outside of low-Earth orbit, NASA and its international partners must be capable of providing a safe and effectivepharmacy. Given few directed studies of pharmaceuticals in the space environment, it is difficult to characterize pharmaceutical effectiveness or stability during spaceflight; this in turn makes it challenging to select an appropriate formulary for exploration. Here, we present the current state of literature regarding pharmaceutical stability, metabolism, and effectiveness during spaceflight. In particular, we have attempted to highlight the gaps in current knowledge and the difficulties in translating terrestrial-based drug studies to a meaningful interpretation of drug stability, safety, and effectiveness in space. We hope to identify high-yield opportunities for future research that might better define and mitigate pharmaceutical risk for exploration missions

The NASA twins study

Domingo, 21 de abril de 2019 Google Scholar Sin comentarios

To date, 559 humans have been flown into space, but long-duration (>300 days) missions are rare (n = 8 total). Long-duration missions that will take humans to Mars and beyond are planned for the2020s and 2030s; therefore, comprehensive studies are needed. The selection of one of a pair of monozygotic (identical) twin astronauts for NASA鈥檚 first 1-year mission has enabled聽 to compare the impact of the spaceflight environment on one twin to the simultaneous impact of the Earth environment on a genetically matched subject.

The conclusion is as following: “Given that the majority of the biological and human health variables remained stable, or returned to baseline, after a 340-day space mission, these data suggest that human health can be mostly sustained over this duration of spacefligh”

Screening for Sleep Apnea in Obese Pilots

Jueves, 7 de marzo de 2019 Google Scholar Sin comentarios

It has long been appreciated that sleep apnea results in poor quality sleep, and that poor quality sleep is associated with daytime fatigue and decrements in performance. However, the relationship between sleep apnea and poor performance, including risk for accidents is not as well understood.

The purpose of this article is to review the basic epidemiology, pathophysiology, and treatment of sleep apnea, including major risk factors for apnea, such as body mass index (BMI), and to look at what is known about the impact of sleep apnea on performance in transportation related occupations.

Hindsight28 : ATC Change

Lunes, 25 de febrero de 2019 admin Sin comentarios

Eamonn Brennan was appointed by the 41 Member States of EUROCONTROL to lead the organisation as its Director General from 1 January 2018. As he highlights, there are many sayings that lead to the point聽 that change in聽 Air Traffic Control聽 is probably necessary, and it is better to embrace it and drive the change rather than resist it. The demand continues to grow, with over 16 million flights forecast by 2040. Our current systems, our current ways of working, will not be able to cope with these traffic levels, therefore there is no other choice but to change

An overview of Aerospace Medicine

Mi茅rcoles, 13 de febrero de 2019 Google Scholar Sin comentarios

Space medicine is fundamental to the human exploration of space. It supports survival, function and performance in this challenging and potentially lethal environment. It is international, intercultural and interdisciplinary, operating at the boundaries of exploration, science, technology and medicine. Space medicine is also the latest UK specialty to be recognized by the Royal College of Physicians in the UK and the General Medical Council.

This review introduces the field of space medicine and describes the different types of spaceflight, environmental challenges, associated medical and physiological effects, and operational medical considerations.

It is clear, concise and easy to read, advisable for beginners and experts alike.

“Aeromedical Advisory” from FAA Safety Briefing

S谩bado, 9 de febrero de 2019 FAA CAMI Library Sin comentarios

It is issued bi-monthly, the FAA Safety Briefing is the safety policy voice for the non-commercial general aviation community. The magazine’s objective is to improve safety by:

  • making the community aware of FAA resources
  • helping readers understand safety and regulatory issues, and
  • encouraging continued training.

One of the sections is about Aeromedical Advisory, and can be interesting, not only for aircrews but also for avaition medical examiners. We encourage to all of you to look聽 through last issue about List Medications and Flight, oftenly requested by airmen; however addressing tghis request is more complicated than it might be seem.

Problemas de Sue帽o en 脪rbita de los astronautas / On Orbit Sleep Problems of Astronauts

Mi茅rcoles, 6 de febrero de 2019 Google Scholar Sin comentarios

Hoy os traemos un interesante resumen sobre los problemas que los astronautas tienen en relaci贸n con los vuelos orbitales. En 2015 la NASA public贸 que la media de horas de sue帽o de los astronautas era de unas 6h/d铆a, por debajo de lo recomendable y adem谩s con una calidad inferior al descanso terrestre. Las causas que se invocan聽 son muchas y variadas: temperaturas poco confortables y ruido ambiental , aislamiento y confinamiento en聽 espacios reducidos, incomodidad de los sacos de dormir, falta de se帽ales propioceptivas familiares, falta de se帽ales circadianas (alteraciones en los “time givers”). Y sus efectos muy conocidos tanto a nivel fisiol贸gico como psicol贸gico, u operacional. Por recordar, un solo detalle, el 70% de los astronautas usan medicaci贸n para mitigar estas alteraciones. Otras medidas para intentar聽aliviar estos problemas聽 son mejorar la calidad medioambiental de la cabina, y designar razonables ciclos de trabajo/descanso, as铆 como聽 apoyo psicol贸gico y soporte social, en astronautas entrenados y formados para enfrentarse a ambientes extremos.

Como resalta 聽Daniel Mu帽oz-Marr贸n- 聽piloto del Ej茅rcito del Aire y Psic贸logo-,聽autor de este art铆culo que hoy te recomendamos leer; 聽se puede decir sin ninguna duda que los Programas de CRM (Crew Resource Management), son la contribuci贸n m谩s importante de la Psicolog铆a Aplicada al mundo de la Aviaci贸n.

Desde su aparici贸n en 1979, estos programas han sido una de las herramientas que se han usado con mayor 茅xito para tratar de afrontar el “error humano” en el mundo de la aviaci贸n.

Te invitamos a leer el 聽presente art铆culo publicado en “Papeles del Psic贸logo” (revista del Consejo General Psicolog铆a en Espa帽a) 聽que realiza un breve e interesante recorrido por la historia de estos programas de entrenamiento.

Inflight Medical Emergencies / Survey from DGLRM 2017

Mi茅rcoles, 30 de enero de 2019 admin Sin comentarios

El art铆culo que hoy os recomendamos fue publicado en “Open Access Emergency Medicine” en Feb/2017. Se trata de un estudio basado en un cuestionario on line remitido a los m茅dicos de la Sociedad Alemana de Medicina Aeroespacial Alemana (DGLRM), que tiene como objetivo conocer las causas m谩s frecuentes de emergencias m茅dicas en vuelos comerciales, as铆 como el equipo utilizado en las mismas. Respondieron 121 m茅dicos , que al menos participaron en una emergencia. Los trastornos cardio-vasculares (40%) y los neurol贸gicos (17.8%) fueron los m谩s frecuentes. El equipamiento m茅dico de abordo se consider贸 suficiente en casi el 80% de las emergencias. El vuelo tuvo que ser desviado a causa de la emergencia m茅dica en el 10.6% de los casos. Documentaron 1 emergencia cada 63 vuelos (por encima de los publicado anteriormente). Los autores recomiendan un registro internacional de emergencias m茅dicas聽 en vuelos comerciales.
