This semester is by far a 100% improvement from the craziness from last semester. With the bits of extra time, I decided to run a half marathon (13.1 miles) to keep myself a little more physically fit than I did last semester. The fall grind was not conducive to anything but studying books and bodies. Therefore I've been training with 5 of my class mates for a marathon in Nashville in mid-March. We run about 4 days a week, 3 of those 4 days we typically run individually and then on Saturdays we do a long run together. This Saturday we are going to try to run ~10.5 or 11 miles. We ran 9.5 miles last week and it was great. Mississippi winters are typically friendly for outdoor running. Mississippi summers are little less friendly. I tried running outdoors last summer in MS and found myself running through sprinklers systems in people's yards. I suspect I'll find a different form of stress relief for the summertime!
I find working out 3-5 days a week a fantastic mental stress reliever. I sleep better at night and my nighttime study routine seems to be more productive as well if I have gone for a run that day. It seems that running is as good for my mental well-being as it is for my physical well-being.
As far as medical school studies are concerned-I spend most of my days and nights studying medical physiology. We spent January studying cardiovascular physiology and we're spending most of February studying the kidneys and endocrine systems. I have to admit the most resounding life lesson I have taken away from the last 6-7 weeks of medical physiology is that if Americans were to lose weight and stop smoking--- A LOT of physicians would be out of work...my peers and I joke all the time about how they should rename medical physiology-"don't get fat/don't smoke 101"
Keep your heart + mind healthy and try to go for a run today! Tt helps you think clearly, relieves tension, and might help you look good for bikini season (if you do know me you know I won't be wearing a bikini I'm way too self-conscious for that LOL) but maybe you can.
Happy Running

LOVE IS A DRUG
I've heard and I'm sure many of you have seen, read, or heard movies, news clips, films, and even songs saying "LOVE IS A DRUG" Some even say its like morphine or another potent pain killer. But the funny thing is if love is like morphine, I don't think I want it...morphine makes you sleepy, drowsy, confused, and if given at high doses makes you itch because morphine causes the release of histamines which are the things that make you itch when you have an allergic reaction--- (p.s.love and itching its a totally different subject). Nonetheless, we continue to describe love as a "drug" or pain killer. Puzzling I think.
CNN posted the following article (see link) saying "love may be as good as morphine"
http://thechart.blogs.cnn.com/2010/10/13/love-may-be-as-good-as-morphine/
I've seen some people on morphine and in my personal opinion, truly loving someone far surpasses any man made concoction that can be made in a laboratory. True unconditional love from Christ will cure any heart, heal any wound, renew any brokeness, and can even give life eternally.
Love could never be a drug and thank goodness it's not.
Happy Valentine's Day to you and yours.

HOLD A BEATING HEART IN YOUR HAND....CHECK!
Yesterday was one of the most interesting days we've had this semester by far!
In the medical physiology class we have a live animal lab in which a live anesthetized pig is used to demonstrate what happens when given certain hormones through a catheters. We gave a variety of injectable hormones to see how hormones these effect the heart rate and blood pressure. We monitored the arterial blood pressure using femoral artery catheters that we inserted ourselves. To do this we had to cut open the thigh area, find the femoral arteries, and cut tiny holes in them to insert plastic catheter tubes. We also exposed the carotid arteries in the neck to test what would happen to blood pressure when the carotids are occluded.
The hormones we gave were epinephrine (this is the same hormone that would be in an "epi" pen) and norepinephrine and acetylcholine. All these hormones have a variety of effects on heart rate and blood pressure and differ at varying dosages. Some made the heart rate RACE up to almost 200 beats per minute while others didn't affect the heart rate much at all. Some of the hormones made the blood pressure SPIKE.
The lab got super interesting when we opened the chest cavity. I cut open the pig on its side in between the ribs bones and through the rib muscle until you could get a tiny view of the lungs. Then we used a metal retractor to spread the rib bones apart to get a better view inside. You could see the bright pink lungs inhaling and exhaling and after removing the pericardium you could see the heart pumping away. It is amazing how much movement is going on inside your chest. Believe me this heart was moving all over the place and pumping hard. It is phenomenal to think this heart beats ~72 beats per min, 24 hours a day, 52 weeks a year, for ~74.6 years (on average). AMAZING.
As part of the lab exercise we caused the heart to go into fibrillation (this is when the heart is not pumping but just quivering and needs to be defibrillated AKA "shocked" with paddles). So after the heart went into fibrillation we defibrillated the heart with internal paddles and tried to get the heart going again. We didn't get the heart pumping with the defibrillator so we tried cardiac message which is using your hand to pump the heart and get blood moving around. After cardiac message you try to defibrillate again to get the heart to beat on its on-- this didn't work either. So our pig's heart beat didn't come back which unfortunately happens a lot when trying to bring a heart back after it goes into fibrillation. Our professor said the heart was probably more difficult to bring back because the pig had be under anesthesia for almost 5 hours at that time.
A couple years ago PETA through a fit when they heard about this lab and I can understand how they would not appreciate us using live animals to practice these surgical techniques. However, I assure you it is far better for med student to practice on anesthetized animals than on someone's relative, friend, child, spouse, ect. These animals provide a purposeful and meaningful experience and help us to be better physicians later on. Believe me all of us appreciated the experience and I can say for myself it was one of the highlights of the semester thus far. Every time you check your heart rate or feel your chest and feel the beating just know that heart is working hard for you! And on a side note: this pig had MUCH prettier lungs than my cadaver had--this pig didn't smoke :) Keep your lungs pretty in pink!
Thanks for reading!

Back to the Med School Grind
Thanks to everyone who kept up with my first medical school semester last fall. The semester ended on December 21st. We took the Gross Anatomy Board exam and the Biochemistry board exam. Both of those are standarized exams that ranks you nationally on a percentile. I usually am a little scared of standarized tests because the MCAT gave me such a fit and the ACT and SAT were not my strongest performances either.
Fortunately, the board exams went much better than my previous standarized test experiences. To any aspiring med student don't let the MCAT determine if you can go to med school or not...I had to take it 4 times and believe me--the MCAT doesn't determine if you will be a good medical student/doctor or not. If you want to go to med school the MCAT is just another hoop to jump through, don't let it get you down.
Back to last semester, so we finished Gross Anatomy (hallejuia!) and Biochemistry (again...hallejuia!) Both those classes went fine and I'm glad to say they are officially behind me. I will continue to say that Gross Anatomy is the "Holy Grail" of medical school. It is the worst, best, hardest, nastiest, most fun, most dreadful, so necessary, so stressful, amazingly rewarding, completely gratifying, and truely unique experience of my first semester. I am not sure any other class will be able to top the emotions gross anatomy envokes.
Nonetheless, today is my first day of second semester or week 20 of medical school. We started the semester with Histolgy (the study of tissues and body systems at the microscopic level). Histology is most important to Patholgist. The T.V. show "Dr. G: medical examiner" is a good example of histology. When Dr. G takes tissues samples and looks at them under the microscope-that's what histology is. We have a histology lab this afternoon, we are going to look at heart muscle, arteries, and veins under the microscope. After lunch we pick up with Medical Physiology. "Med Phys" will run all the way through Spring Break and will be the bulk of this second semester.
I hope each of you had a very Merry Christmas and a Happy New Year. Again, thanks to each of you for reading and praying for me during this first year. I appreciate it more than you know.
