Imagine you are in the hospital. A patient comes to you and you suspect this patient has COVID-19. What should you do? In this article, I am going to explain the diagnostic tools used to diagnose COVID-19 If you haven't read the article on the pathophysiology of COVID-19, please go check it from the link below as this will help you understand many details here. https://curiosnerd.blogspot.com/2020/04/updated-how-people-die-from-corona.html 1- Check vitals If the patient is:  hypotensive ---> it could be a septic shock (due to cytokines storm explained in the previous article) hypertensive ---> doesn't signify anything but it is not good because hypertensive patients are at high risk to develop serious complication due to the infection Look for tachycardia ---> sign of hypoxemia Look for respiratory rate ---> if more than 20 ---> again it could be due to hypoxia Check temperature ---> if high --> sign of inflammation --> probably due to CO...

UPDATE: I HAVE UPLOADED THE DIAGNOSTICS PART COVID-19 Diagnostics UPDATE: HOW OUR WORLD WILL BE IMPACTED AFTER THE PANDEMIC IS OVER ? https://curiosnerd.blogspot.com/2020/07/how-our-world-will-be-impacted-after.html?m=1 I am very glad that you decided to watch the second part of the mechanism of death in people who get infected with the coronavirus. In the previous article, I mentioned some mechanisms. However, we now know more about this virus and its other mechanisms with additional details that are available now. Check the first article from here:  https://curiosnerd.blogspot.com/2020/03/how-people-die-from-corona-virus.html 1- Well, as we know the coronavirus is transmitted by air droplets. Let's say someone sneezes in front of you and you inhale the viral particles that came out from his mouth. The viral will travel directly to your respiratory system infecting the lining epithelial cells of your bronchi, bronchiole, and, most important, alveoli. It enters the cells thro...

There is no doubt that lymphomas are one of the most aggressive cancers we have ever seen. Did scientists finally find treatment for it? Before anything we need to decide which type of lymphoma you are talking about. There are 2 main categories of lymphomas: Hodgkin and Non-Hodgkin. Hodgkin lymphoma: Usually, the Hodgkin lymphoma is the good one. It is not as aggressive as non-Hodgkins. Also, its spread is usually predicted. It spreads from one lymph node (usually cervical lymph nodes) to the next in the lymph vessels. It doesn’t spread in the blood, so it doesn’t produce masses in other organs such as the liver, brain, and bones. So, it is treated with radiation and it responds well. It has a good prognosis in general. Non-Hodgkin lymphoma: They are the bad ones. They start extranodal, but they can also begin in the lymph nodes. They have a bad prognosis. Their spread is not predicted. They reach the blood and can invade other organs including the bone marrow. So, we can say...

Studying medicine is not just studying. It is an addiction. I think I can't do anything in life other than medicine. If it was a woman, I would marry her. Let me show you why and you tell me if it is worth it or not.  Do you know how you looked like when you were an embryo? You were a trilaminar disc. You were literally a disc composed of 3 layers that gave rise to all your body Do you know the layers of your abdomen before the stomach? We know it because we do this when doing surgery Did you know that there are around 15 kinds of anemia not only iron deficiency anemia (anemia due to decreased intake of iron) that people think that it is the only kind of anemia? Do you know how iron deficiency causes anemia at the molecular level? We know Did you that the Iron you take from meat and animal products is more absorbable than iron you take from vegetables? Do you know why when you stand-up suddenly you feel dizzy and feel like someone turned the light...

Failure is inevitable. It hurts but It teaches a lot. I worked for months preparing myself to apply for US colleges. I stayed up countless nights writing my essays, studying for my SAT, working my GPA, and doing lots of other things. I dreamed of studying at any of these elite universities. I applied to over 20 universities, but guess what? I got rejected from all of them. I vividly remember the moment when I realized that all the doors are closed in front of me. I knew that I am not going to make it and I will have to continue studying in my home country. I was destroyed from inside. I spent some nights crying, wondering where did all that EFFORT I made through the year go? I was immensely hopeless.  Later, I got into one of the great universities in my country for studying medicine. I made a lot of friends and I started to feel satisfied. Now, I am really ambivalent and don’t know whether to apply again to the US or to stay in the place that...

Humans are no more than animals with large brains. Let me tell you the story from the beginning. In the past time, there were different types of humans in a big family (genus) called homo and different species such as sapiens, habilis, and erectus. Sapiens represent modern humans. The only sapiens could survive until now. There are many theories that hypothesize the reason why sapiens lived but I will not get to them. For an unknown reason, the genus homo had large brains that made us unique compared to other species. Maybe it was just by chance. It could be random mutations that just happened to us. But we paid the price for these big heads. The old human was actually muscular unlike know, but because these brains need a huge amount of fuel “food” that wasn’t available back in that time, our bodies paid the price through muscle atrophy. Our muscles atrophied and shrunk in size to provide a source of energy to our brains. This explains why humans don’t have huge bodies suc...

DISCLAIMER: THE POST CONTAIN SOME PHOTOS THAT MAY BE DISTURBING FOR SOME PEOPLE Over 1 million people all over the world are affected by the virus, and there is around 50k death. Who is responsible for all of this? Is it just a coincidence? someone designed it in a Lab? In my opinion, It is the human’s greed and insatiable longing for money.  Let me explain to you why. We all aware that this virus came from Wuhan, China. Specifically, from the wet markets where Chinese people sell meat and fish from an animal called pangolin. Back in 2002, a similar virus called SARS appeared and it is believed to be originated from an animal called civet cats. Chinese sellers who get in contact with this animal (yes Chinese people eat cats and dogs) were infected and they spread the infection to the rest of the world. It is believed that because of these wet markets , the virus originated and if they weren’t there, the virus wouldn’t have come at all. So, wet markets were closed since they we...
