8 Super Foods for Medical Students

Med school is hard, it’s complex, and there’s a lot of things to learn. A typical day would be to attend a lecture during the day and hitting the books in the evening. Reviewing the note sheets and reading ahead. An hour or so for meals, exercise, and TV. Weekends are a respite, there is no new stuff coming in. Both days can be spent in reviewing the week’s notes and material. A bonus would be quality time with friends and family. Everything steps up a notch on test days. You have to work harder and be ready to change things if they don’t work. As you progress you gain a better sense when to cut corners. Free more time for important things, rather than trade sleep for fun. The brain takes a lot of pounding and what you eat takes a toll on your brain. Learning more about brain foods matter, it will boost memory and focus. Your food choices can enhance the health, vitality, and functionality of your precious brain Brain super foods rich in antioxidants, good fats, vitamins, and minerals provide energy that protects the brain against diseases and keeps it in tip-top shape. GEP Limited, a medical electives overseas provider, rounded up 8 brain foods to feed your mind and body. Delight in this concoction we’ve prepared that is a mix of fruits, veggies, oils...

The Flu Shot: It’s Not Just About You

It’s that time of year again. The powers that be (a.k.a. the CDC) have hedged their bets on this year’s flu vaccine components, and they will be encouraging patients to get vaccinated before the end of October, so that the body has plenty of time to develop resistance before flu season sets in. For the 2017-2018 flu season, the CDC has recommended that three-component flu vaccines contain the following: – an A/Michigan/45/2015 (H1N1)pdm09-like virus (updated), – an A/Hong Kong/4801/2014 (H3N2)-like virus, and – a B/Brisbane/60/2008-like (B/Victoria lineage) virus. Four-component vaccines are recommended to contain a B/Phuket/3073/2013-like (B/Yamagata lineage) virus. In a deviation from previous years, the CDC recommends against using a nasal spray flu vaccine, also known as the live attenuated flu vaccine (LAIV) due to concerns about effectiveness. Sure, a shot can be a few seconds of pain, but it’s better than being laid out for days if you do contract the flu. For the first time, the CDC has approved a true cell-based candidate vaccine virus, in addition to those traditionally produced using fertilized chickens’ eggs. Many medical practitioners will likely get the flu vaccine, but how do we encourage more patients to get it too? Because the flu is not a reportable disease, the CDC uses modelling to estimate the number of infections each year. They currently estimate that in the U.S., the number of cases has been somewhere between 9.5 million and 35.6 million every year...

How Exactly Does Smoking Affect the Environment?

We all know that smoking is harmful to the human body, but there is actually a second damaging side to smoking and cigarettes. Both cigarette smoke itself and the waste from cigarettes can have a major impact on the environment. In this infographic below, we’ll take a look at just how much damage smoking does on the environment and highlight some off the shocking statistics surrounding recklessly discarded cigarette butts too. Now only does smoking have an effect on your health; it also has an effect on your wallet. Smoking has been one of the biggest health concerns for decades now, but did you know smoking can cost a person between $6,500 and $13,500 a year? The average cost of a cigarette averages out to be around 31 cents, which comes out to $1,358 a year. The hidden costs come in the form of higher insurance premiums and loss of insurance credits. The total cost of smoking with these factors adds up to a much greater financial sacrifice. So, if you’re looking to quit, how do we kick the habit? This study shows the difference between reward and penalty based systems: In a study of 2,500 smokers affiliated with CVS, participants were enrolled in two different programs: a reward-based one and a penalty-based one. In the reward based-program, individuals were offered an $800 reward if they were able to...

Want to Improve Fitness? Make it a Game

From studying, to exercising, to cleaning up, and yes, fitness – how do you make yourself do something that you don’t want to do? Make it a game! Even Mary Poppins tells us that “in every job that must be done, there is an element of fun,” and apps like Streaks are popping up all over the place to make a game out of any mundane activity. But does it work? Researchers from the University of Pennsylvania and Boston University set out to test the theory that participants could be incentivized to increase their physical activity through the gamification of exercise. All participants in the study wore step counters to measure their daily activity and received feedback each day on their achievements. However, those in the intervention group were given the opportunity to earn points and progress through reward levels as they increased their physical activity. Image: Fitbit by Hamaza Butt / CC by 2.0 The designers of the study took special care to incorporate principles from behavioral economics to augment social incentives and overcome participation barriers. Studies have shown that people tend to be more motivated to avoid losses, and that good habits are better sustained with variable reinforcement. Participants were enrolled with their entire families, and asked to sign a commitment pledge to do their best during the trial. Each week the family was awarded 70 points,...

Robot Therapy: Can a Software Program Treat Depression?

Although traditional talk-therapy sessions are conducted face-to-face, advances in smartphone technology and video-calling have significantly altered the age old “therapy couch” model and brought talk therapy into the lives of people who aren’t able to visit a therapist regularly. Further advances in artificial intelligence may mean that someday patients might not need a therapist at all – just a computer program. Image: The Doctor Is In Your Pocket by Juhan Sonin /CC by 2.0 Researchers at Northeastern University in Boston have developed and tested a computer program that directly interacts with patients, in between their regular therapy sessions, that helps to reinforce outcomes from the group therapy and teach techniques to manage stress. Advances in conversational artificial intelligence have enabled computer scientists to develop software programs that interact with patients, either through voice or text, in such a natural way that some patients’ brains respond to these programs the same way they would when talking to a human. These programs are known as “conversational agents,” and they have been particularly successful at psychological evaluations, as studies have shown that patients may be more likely to give open and honest responses when they believe they are speaking to a computer program rather than a human. The researchers at Northeastern found that, when combined with group therapy visits, patients who used the conversational agent along with their group sessions had significantly better...

How One Woman Pioneered Breast Cancer Research

The BRCA1 protein is a caretaker of the cell. When DNA becomes damaged, BRCA1 helps restore the DNA to its proper form or initiates program cell death if it is beyond repair. This ensures that cells maintain their intended function. However, if BRCA1 itself becomes damaged, it can no longer perform its essential role. Its importance is highlighted by the finding that when this occurs, there is a greater risk for developing cancer. Discovery of BRCA1’s relevance to cancer in 1990 was groundbreaking because it established that there is a genetic component to cancer, not just viral as commonly thought at the time. More so, it has allowed for screening for mutations in BRCA1 and the related BRCA2 gene that can identify at-risk women so they can receive life-saving treatments. These mutations are thought to be responsible for approximately 3-8% of breast cancer cases in the U.S. and up to 25% of inherited breast cancer. What may be even more remarkable than this discovery is the woman who discovered it, Mary-Claire King. Dr. King identified the BRCA1-cancer connection at a time when the idea of genes playing a role in cancer was radical. As a self-described “stubborn person”, she persisted and continued to push the idea forward. At the same time, she took on a leadership role as a scientist, despite training at a time when independent female scientists...

Pig DNA is Considered Identical to Human DNA

Scientists at Recombinetics are conducting research on pigs in an effort to accelerate cancer cure development and potentially create a sustainable source of genetically-matched human organs for transplantation. While experiments involving farm animals are nothing new in the world of medical research, the pigs at Recombinetics farm in Minnesota are unique because they have been modified to express human traits using TALENs technology. Cancer has been cured in mice models many times, but the same techniques do not seem to translate well in humans. The company believes the 98% similarity between the human genome and the pig genome may help close the gap between successful cures in animal models and resulting efficacious treatments and/or cures for humans. Click here to read more about this company’s research on CNBC. Earlier this year, researchers were able to identify that DNA Bacteria can store information, like hard drives: Researchers at Harvard Medical School have used the CRISPR gene-editing tool to encode five frames of a vintage motion picture into the DNA Bacteria of E. coli bacteria. By reducing each frame into a series of single-color pixels and matching each color to a DNA code, the scientists were able to string together DNA strands that represented the video frames. Non-biological information has been encoded into DNA before, going back as far as 2003. However, this is the first time living organisms have been used as the message’s vessel. Living...
