Are Energy Drinks Really That Dangerous
Before you reach for the energy drink, you may want to reconsider. They may kill you. Hey guys, Amy with you on DNews today. Energy drinks have become common in the United States in recent years offering a quick energy boost to match a fastpaced life. And they work because they're packed with sugar, caffeine, and other stimulants, none of which are great for you in large doses. The sugar in energy drinks hits your system first, giving you a spike of energy then a crash. The crash is offset by caffeine, which stimulates the central nervous system with.
A bit of a time delay. Peak caffeination hits after about an hour, and the increased energy can last all day as it slowly wears off. It's safe to ingest about 400 mg of caffeine per day if you're a healthy adult. For perspective, a 16 ounce grande brewed coffee from Starbucks has 330mg of caffeine, a grande Americano with two shots of espresso has 225mg, a 16 ounce can of Rockstar has 160mg, and one 8.4 ounce can of Redbull has 80mg. Consuming caffeine is known to cause heart palpitations, anxiety and insomnia. It's a.
Diuretic, causing the kidneys to process extra fluid into urine leaving the body severely dehydrated. It can also become addictive meaning the body will need more to feel the stimulating effect, and the cycle continues. Where energy drinks are concerned, the effects of caffeine are amplified by stimulants. Ephedrine is a nervous system stimulant often found in these drinks. So is guarana, a South American shrub whose seeds contain more caffeine than a coffee bean. And so is taurine, an amino acid that acts as a neurotransmitter. But in moderation it's fine, right.
Well, maybe not. A study from the Mayo clinic says that even one energy drink can cause momentary health changes that could increase the risk of heart conditions over time. The study had adults abstain from caffeine and alcohol before consuming either an energy drink or a placebo. Those who drank the real thing showed a marked increase in caffeine levels, blood pressure, and norepinephrine levels, the sudden spike of which could predispose those people to cardiovascular problems down the line. We're already seeing this happening ER visits related to the high caffeine and taurine.
Levels in energy drinks have doubled in the last decade, particularly in patients between 18 and 25. Another study found a correlation between energy drinks and traumatic brain injuries in young adults. The EU Scientific Committee on Food found that increased caffeine intake brought behavioral changes including increased arousal, irritability, and nervousness. One woman in the UK actually started losing her sight because of an energy drink habit! The sugar in the drink caused her to gain weight, and at 364 pounds she developed Idiopathic intracranial hypertension. Her optic nerves swelled, leading to temporary blindness.

The Blood Typing Game
The Blood Typing game is an educational game that teaches students about the human blood types by administering virtual blood transfusions to patients. When you receive your patient, you need to discover their blood type before performing the transfusion. First, use the syringe to draw your patient's blood and deposit it into three test tubes. The test tubes contain three different reagents with either A, B or Rh antibodies. The antibodies attach to antigens on the patient's red blood cells if they match. No agglutination in test tube A indicates that the patient does not belong to blood.
Group A. Agglutination in test tube B indicates the patient does belong to blood group B. In test tube Rh, the blood is Rh positive if there is clumping, and Rh negative if there is no clumping. We know that this patient's blood type is B positive because clumping occured in the test tubes containing B and Rh antibodies. Check to see how many bags of blood your patient needs. Select the bags of blood that are compatible with your patient's blood type. People can safely receive blood from the same blood type as their own, but also from some.
Other compatible blood types. This Compatible blood chart shows which bloods are compatible with the others. Our patient can obviously receive B positive blood, but can also receive B negative, O positive, or O negative. If you give your patient the wrong blood type, the red blood cells from the donated blood will clump, which can have fatal consequences for the patient. The blood typing educational game helps students understand bloodtyping through visual enforcement in this handson animated game. It is an excellent tool for teachers to use in the classroom.
Risks and benefits of stroke and AFib medications
Dr. Curtis, what are the risks and benefits of medications to treat stroke or atrial fibrillation Well, the obvious benefit is to prevent the stroke in the first place. Or, if a patient's already had a stroke, to prevent the next one. So that's the benefit from it. The risk for these drugs, whether they are aspirinlike drugs which technically go by term antiplatelet agents, or anticoagulants, or other kinds of blood thinners, they work in different ways to prevent clots. But in both cases, because they are trying to prevent clots, they can actually promote bleeding.
So the biggest risk factor for any of these drugs is the risk of bleeding. However, in patients who are high risk, the risk of stroke is high enough that you get a benefit from giving the drugs. So the benefit is that the risk of stroke is reduced so much that in my opinion, and I'm sure yours as well, that far outweighs the risk of bleeding that we have with them because it's relatively low. What we really want to do is prevent strokes in patients whether they are at risk for it because of atrial fibrillation, or because of other reasons.
I absolutely agree. The lack of anticoagulation resulting in stroke is such a detrimental thing to the patient and family, and for us too. So we need to be very careful in selecting the patient who's appropriate and should be on anticoagulants. For older patients with a high risk for falls or bleeding, those are a little bit of a tricky situation. What do you think about these things That's the common misunderstanding people think that if you're at risk for falling that you can't be on anticoagulants. I know there was a study that was done some years back,.
That someone would have to fall at least two hundred times to have the risk of taking these blood thinners outweigh the benefits you're going to get from preventing stroke. So that's one common misconception. Another important point I'd like to make is that when patients have strokes related to atrial fibrillation they tend to be worse. They tend to be more devastating than strokes for other reasons. So patients who have a stroke related to atrial fibrillation are more likely to be bedridden and more likely to require longer term care than strokes for other reasons.
Mexican People Try Taco Bell For The First Time
I don't think it's gonna be close to the Mexican food whatsoever. Yeah, it doesn't look like a taco whatsoever. To me it does. Looks like a salad. A taco isn't usually in a flour tortilla, I mean Both It comes in corn. girl laughs I mean, looks like your basic burrito. Beans, rice, chicken, guacamole. Why is the rice white I can totally eat some of these. I don't know if this is mayonnaise or sour cream, but Yeah, I can't even tell, it tastes like mayonnaise.
TomorrowsDiscoveries Neurons That Control Biological Rhythms and Sleep Dr. Seth Blackshaw
Music gtgt The brain is an amazingly complex structure made up of thousands of different types of nerve cells, or neurons. These neurons form the basic building blocks that make up thoughts, feelings, and appetites. By understanding how these neurons are formed, we can better understand how they work. That is what I do. I study how neurons in a cherrysized part of the brain called the hypothalamus are formed. The hypothalamus is a mass deregulator of many behaviors including biological rhythms, sleep, and feeding. My lab has identified genes that control the formation.
