Let’s Talk About Food...in Space!

It’s Thanksgiving time…which means you’re probably thinking about food…

Ever wonder what the astronauts living and working on the International Space Station eat during their time 250 miles above the Earth? There’s no microwave, but they get by using other methods.

Here are some fun facts about astronaut food…

Astronauts are assigned their own set of silverware to use during their mission (they can keep it afterward too). Without a dishwasher in orbit, they use special wipes to sterilize their set between uses, but it’s still better for everyone if they keep track of and use their own! So many sets of silverware were ordered during the space shuttle program that crews on the space station today still use silverware engraved with the word “shuttle” on them! So #retro.

You probably know that astronauts use tortillas instead of bread to avoid crumbs floating everywhere. Rodolfo Neri Vela, a payload specialist from Mexico, who flew on the space shuttle in 1985, introduced tortillas to the space food system. Back then, we would buy fresh tortillas the day before launch to send on the 8-10 day space shuttle missions.

We then learned how to reduce the water activity when formulating tortillas, which coupled with the reduction of oxygen during packaging would prevent the growth of mold and enable them to last for longer shuttle missions. Now, we get tortillas from the military. In August 2017, acting NASA Administrator Robert Lightfoot ate a meal that included tortillas from 2015!

Our food menu is mostly all made from scratch so it can meet the requirements of the nutrition team and ensure astronauts eat enough fruits and vegetables. The space station is stocked with a standard menu that includes a mix of the more than 200 food and drink options available. This ensures lots of variety for the station crews but not too many of each individual item.

The food is packaged into bulk overwrap bags, referred to as BOBs, which are packed into cargo transfer bags for delivery to the space station. Each astronaut also gets to bring nine personalized BOBs for a mission, each containing up to 60 food and drink options so they can include more of their favorites – or choose to send a few specific items for everyone to share on a particular holiday like Thanksgiving. As a result, the crew members often share and swap their food to get more variety. Astronauts also can include any food available at the grocery store as long as it has an 18-month shelf life at room temperature and meets the microbiological requirements.

Fresh fruit and vegetables are a special treat for astronauts, so nearly every cargo resupply mission includes fresh fruit and veggies – and sometimes ice cream!

The Dragon spacecraft has freezers to bring science samples back to Earth. If there is space available on its way to orbit, the ground crew may fill the freezer with small cups of ice cream or ice cream bars.

Some food arrives freeze-dried, and the astronauts rehydrate it by inserting a specific amount of hot or ambient water from a special machine.

Other food comes ready to eat but needs to be reheated, which crew members do on a hot-plate like device. We recently also sent an oven style food warmer to station for the crew to use. And of course, some food like peanuts just get packaged for delivery and are ready to eat as soon as the package is opened!

Our nutritional biochemists have discovered that astronauts who eat more fish in space lost less bone, which is one of the essential problems for astronauts to overcome during extended stays in space. In the limited area aboard the space shuttle, not all crew members loved it when their coworkers ate the (aromatic) fish dishes, but now that the space station is about the size of a six-bedroom house, that’s not really a problem.

Astronauts on station have had the opportunity to grow (and eat!) a modest amount of fresh vegetables since the first lettuce harvest in August 2015, with new crops growing now and more coming soon. Crew members have been experimenting using the Veggie growth chamber, and soon plant research will also occur in the new Advanced Plant Habitat, which is nearly self-sufficient and able to control every aspect of the plant environment! 

Growing food in space will be an important component of future deep space missions, and our nutritionists are working with these experiments to ensure they also are nutritious and safe for the crew to eat.

My endocrinologist said that I have the 3 F’s of Hypothyroidism: Forgetful… um…

Yeah, you’re hypothyroid alright.

(I think the other two are “Freezing” and “Fat”, but I’m just assuming at this point.)

Shouting at the TV when a character says something related to your field that’s completely wrong

On Agents of Shield a character referred to the “adrenal cortex of the brain” and then said something about fear originating in the reticular activating system. NO! Basically this poor actor must have been told to vomit a neuroscience textbook at the camera.

Step 1 of reading a research article:

Check the number of pages that are for references, along with how many figures and tables are included. Recalculate accordingly how many pages of reading there actually are.

How to read a textbook?

Alright fellow studyblrs, I have a confession to make: I have only read ONE of my textbooks in my couple of years of college.

I want to read my physiology book this semester, but I’m stuck on how to effectively read and take notes. There are loads of terms and concepts on each page and if I take notes on them how I would usually take notes, I would only get through six pages per hour. This is not efficient and I will ultimately give up if I stick with this. However, I can’t just skim and not take notes.

So my question is, how can one effectively read a textbook without getting bogged down in it or walking away without notes? I desperately want to figure this out and succeed this semester.

[stressedwithmedicine]

These are the things I usually do, I can’t guarantee that it’ll work for you but I hope my input (among others) helps you come to a conclusion!

1. Write what you understand, not what you read. If you can express what you’ve just read in your native tongue, write it in your native tongue. If you can associate the description with a previous experience, write your experience (feel free to use words like “remember when…” or “kinda like…”–it’s YOUR notes!). Do it your own way.

2. If a concept or a load of information can be drawn, draw it. It doesn’t have to be a perfect drawing or a highly accurate representation of the information, but draw it as you understand it. Not only will this save time (if you express a bulk of information into a tiny drawing), but this will also help in remembering when the need arises.

3. Shorten long, unique words if they keep on getting repeated. I remember just writing “elas.” for elasticity, “A & B” for Acid and Base, “e-” for electrons, etcetera. I used to do this in general words too, like if the word’s something like “positive” I’d usually just write the “+” sign, or if the word’s “high” or “increase” I’d draw a upward arrow.

These are the things I can think of right now. Hope I helped!

Agree with what’s been said !!

To add: Sticky notes really help me when I don’t have time to take notes from loooong pages in my textbooks. I tend to read the page half-thoroughly and then decide what’s most important. These important sentences/formulas/rules/bullet points/… I write on sticky notes which I then stick right next to the passage where it is explained. I guess this especially works if you remember things by picturing pages and stuff. Oh and these sticky notes usually are a good base for actual notes.

Good luck, you’ll find a way through those pages!!

[accioneuromed]

Thank you @stressedwithmedicine and @plantsandcoffeestudyblr for these tips! These remind me of what I actually used to do when I was very disciplined with reading my first neuroscience text book; my favorite method was synthesizing information in my own words and writing it on a sticky note on the same page.

Female Endocrinology - overview

General endocrinology info:

Autocrine - affects same cell

Paracrine - affects a nearby cell

Endocrine - affects elsewhere in the body (secreted by glands into the bloodstream)

Exocrine - secreted by glands into the external environment (eg sweat, saliva)

Steroid hormones

Oestrogen

Progesterone 

Testosterone

Cortisol

Non-steroid hormones

Glycoproteins (LH, FSH, TSH, hCG)

Proteins (GH, prolactin, others include insulin, PTH)

Peptides (oxytocin, gonadotropin releasing hormone)

Amino acid derivatives (triiodothyronine, thyroxine (T4), adrenalin)

Anterior pituitary secretes LH and FSH (gonadotropins)

Menstrual Cycle

Follicular phase

prepares follicles for ovulation

uses LH, FSH, oestrogen

FSH (from ant. pituitary) stimulates growth and maturation of several primary follicles

each produce oestrogen which helps regenerate/prepare endometrium 

one follicle eventually becomes dominant and the others degenerate (~day 7)

Preovulation

Graafian follicle sends a surge of OES through bloodstream

resulting LH surge prompts next stage - ovulation (~day 14)

Ovulation

follicle does not enter fallopian tubes

ovum erupts from follicle 

fimbrae sweep up ovum, muscular contractions help guide it down the tube

Luteal phase

following ovulation cells of the ruptured follicle enlarge and form the corpus luteum

corpus luteum produces progesterone, growing for 7-8 days. if no fertilization, growth stops and progesterone slows 

Outcome 1: Fertilization 

Egg lives for 12-24 hours

takes 5 days to reach uterus (fertilization must occur in uterine tube)

endometrial development continues with progesterone production

formation of placenta after implantation from trophoblast - it will take over progesterone production and signal corpus luteum to degenerate into corpus albicans

Outcome 2: No fertilization 

no blastocyst means no hCG to ovary

corpus luteum stops action, degenerates

drop in progesterone causes constriction of endometrial arterioles - leads to endometrial ischemia

causes spongy endrometrial tissue to slough off - menstrual bleed

Addison’s Disease.

Addison’s disease is a rare but known disorder (John Fitzgerald Kennedy suffered from it) and it is also referred to as adrenal insufficiency. Adrenal insufficiency develops when adrenal glands do not produce enough of the hormone cortisol. This can happen due to a problem within the adrenals (called Addison’s disease or primary adrenal insufficiency) or due to a problem with ACTH, the signal the brain sends to the adrenals instructing them to make cortisol (called secondary adrenal insufficiency).

An important distinction for patients is that people with primary adrenal insufficiency (Addison’s disease) usually don’t make enough of the hormone aldosterone too; so in addition to taking cortisol replacement, they also need aldosterone replacement. Also, ACTH levels are elevated. People with secondary adrenal insufficiency are only low on cortisol. 

Causes: Primary adrenal insufficiency - the outer layer of the adrenal glands is called the adrenal cortex. If the cortex is damaged, it may not be able to produce enough cortisol. A common cause of primary adrenal insufficiency is an autoimmune disease that causes the immune system to attack the adrenal gland(s). There are some very rare syndromes (several diseases that occur together) that can cause autoimmune adrenal insufficiency, such as Autoimmune Polyendocrine Syndrome (type 1 or type 2). Other causes include: amyloidosis; bleeding into the adrenal glands; cancer that spreads to the adrenal glands; infections (bacterial, fungal, tuberculosis) of the adrenal glands; surgical removal of the adrenal glands. Secondary adrenal insufficiency - it is caused by a lack of ACTH, made in the pituitary gland. By far the most common cause of this type of adrenal insufficiency is chronic steroid use.

Signs and symptoms: 

Weakness

Fatigue

Abdominal pain

Nausea

Weight loss

Low blood pressure

Increased pigmentation of the skin, including areas not exposed to the sun (due to high levels of ACTH in primary adrenal insufficiency. This occurs because melanocyte-stimulating hormone (MSH) and ACTH share the same precursor molecule, pro-opiomelanocortin (POMC))

Salt craving (due to low levels of aldosterone in primary adrenal insufficiency)

Postural Hypotension

Depression

Treatment: it involves replacing the cortisol and/or aldosterone that the body is not able to produce, or that it secretes in an insufficient quantity. Cortisol is replaced with an oral synthetic glucocorticoid. The drug is taken one or two times each day. Aldosterone is replaced with an oral mineralcorticoid.

I missed my first day back to uni and...

I now have 2 absences in my attendance and;

All the endocrinology to learn by myself ‘cause it was taught in the first class of physiology and I missed it and;

An entire chapter in pathology to study at home for me to catch up ‘cause you’ve guessed it, I MISSED;

Never. Miss. School. Kids. I had to because I needed to schedule my eye surgery and get some papers to finish the bureaucracies required for this school year (and I still need some more).
