In space, no one can hear your red blood cells scream
There are many reasons why space is the final frontier, not least of which are the major health issues space travel places on the human body. So until a shady billionaire finds an alien protomolecule on a Saturnian moon and starts splicing it with human DNA so we can hang out in space all day without a spacesuit, we’re stuck with things like space anemia, a condition many astronauts develop after extended time in space.
Space anemia has been known for many years, but it was assumed that it developed as a reaction to microgravity and was a short-term phenomenon only – a temporary compensation as fluids and blood volume adjusted themselves. But as new research shows, that assumption seems to be wrong.
For the study, published in Nature Medicine, 13 astronauts who were in space for at least 120 days – long enough for all their red blood cells to have been produced in space – had their blood tested consistently. Before their flights, the astronauts created and destroyed 2 million red blood cells per second, but while they were in space, they destroyed 3 million cells per second. Notably, this process continued for the entire duration of the space flight. So, not a temporary reaction.
Consequently, 5 of the 13 astronauts developed anemia when they returned to Earth. (Interesting space fact: Having fewer blood cells isn’t a problem while you’re in space; the effects of anemia only manifest when the body returns to full gravity.) The anemia disappeared after a few months, but the astronauts were still destroying 30% more red blood cells a year after their spaceflight than they were before leaving Earth.
You may be thinking: Well, if they were destroying 50% more red blood cells while in space, how come they didn’t all develop severe anemia? The researchers theorized that production was boosted as well, which sounds like a good thing. The body is compensating, as it should. Unfortunately, that increased production stresses bone marrow function and the demand for energy spikes. That’s not such a good thing. And of course, many of the astronauts got anemia anyway.
To tackle the issue, the researchers emphasized the importance of feeding astronauts a proper diet, plus potential supplements before spaceflight. So don’t worry, Captain Kirk will be able to arm wrestle Klingons and romance suspiciously human-looking aliens without fear of keeling over from anemia-induced fatigue. Earth will stay safe.
Tell me with your eyes
Communication can be hard, even under the best of circumstances, but for many nonverbal patients in the intensive care unit who can’t move, getting a point across to the health care team can be a huge struggle in itself.
Health care professionals have been making do with eye-blinking or head-nodding, but what if that’s just not enough? New research shows that it’s not, and there’s a more effective way for patients to say what they mean just by looking.
In a study published in the Journal of Trauma and Acute Care Surgery, researchers looked into using eye-tracking systems for nonverbal ICU patients to communicate. Eye-tracking isn’t anything new, but using it as a form of communication among nonverbal patients with critical illness hasn’t been looked at before.
How does it work? The eye-tracking system is set up in the patient’s line of sight and its various algorithms and software collect data to calculate where exactly the patient is looking. Established scores and scales assess the patient’s mood, quality of life, pain, and self-esteem.
The researchers found that participating patients were actually experiencing more negative moods, pain, and feelings of frustration than was once believed. Making this tool even more valuable for treatment adjustment and meeting patients’ needs.
In this case, it means that health care providers are getting an eyeful … of communication.
Make America grave again
Here we go again. Somebody just found something else that the United States is not the best at. To go along with math and science education, infrastructure investment, quality of life …
That’s going to go on for a while, so let’s get to the new stuff. An international group of researchers surveyed end-of-life care in 81 countries and ranked them based on the assessment of 181 experts in those countries. They looked at 13 different factors, including proper management of pain and comfort, having a clean and safe space, being treated kindly, lack of cost barriers to appropriate care, and treatments that address quality of life and don’t just extend life.
… press freedom, industrial production, racial equality, Internet connectivity …
Their report card, published in the Journal of Pain and Symptom Management, gave six countries an A, with Great Britain at the top. The other five were Ireland, Taiwan, Australia, South Korea, and Costa Rica. The lowest grade went to Paraguay in 81st place, with Lebanon, Brazil, Senegal, and Haiti just ahead.
… environmental stewardship, body-mass index, social mobility, COVID safeness …
The United States, getting a firm grasp on mediocrity, ranked 43rd. Here are some countries that did better: North Macedonia (7th), Sri Lanka (16th), Uganda (31st), and Uruguay 33rd). In the United States, “we spend so much money trying to get people to live longer, but we don’t spend enough money in helping people die better,” lead author Eric A. Finkelstein, PhD, said in a written statement.
… economic stability, and soccer; we’re also not the best at dying. Wait, did we already say that?
The face mask that launched a thousand ships
Face masks, clearly, have been a source of social strife during the pandemic. People may not agree on mandates, but a mask can be a pretty-low-maintenance face shield if you don’t feel like putting on make-up or want to cover up some blemishes.
Before the pandemic, people thought that those wearing face masks were less attractive because the masks represented illness or disease, according to Dr. Michael Lewis of Cardiff (Wales) University. Back then, no one really wore masks besides doctors and nurses, so if you saw someone wearing one on the street, you probably wondered what they were trying to hide.
Now, though, the subject of face mask attractiveness has been revisited by Dr. Lewis and his associate, Oliver Hies, who found that face masks now make people more attractive.
“Our study suggests faces are considered most attractive when covered by medical face masks. … At a time when we feel vulnerable, we may find the wearing of medical masks reassuring and so feel more positive towards the wearer,” Dr. Lewis told the Guardian.
He suggested that we’re no longer looking at people wearing a mask as disease riddled, but rather doing their part to protect society. Or maybe we focus more on someone’s eyes when that’s all there is to look at. Or, maybe we wind up making up what the rest of someone’s face looks like to meet our attractiveness criteria.
However you feel about masks, they’re cheaper than plastic surgery. And you can go out wearing a new face every day.
