Ischemic Stroke.-Raina Tamakuwala

There are some unknown threats to each of our life which are either physical or Internal.We are well aware of the physical threats which may happen in the environment,we are living in and we know several ways to stop them from happening or we avoid it, but how exactly do we plan to avoid or stop our internal body threats, It is a fact that there is no possible way we can control  the functioning of our internal body.Which is why it is at least important for us and our community to be aware of what all types of internal emergencies can happen.Mostly medical emergencies happen after age 60 years. Most common emergency is Strokes.

 

  • A stroke is a sudden interruption in the blood supply of the brain. Most strokes are caused by an abrupt blockage of arteries leading to the brain (ischemic stroke). Other strokes are caused by bleeding into brain tissue when a blood vessel bursts (hemorrhagic stroke).

 

As one fourth of strokes occur in people aged 65 years. UK current policy calls for services that meet the specific needs of working-aged adults with stroke. It  aimed to identify the social consequences of stroke in working-aged adults, which might subsequently inform the development and evaluation of services for this group development and evaluation of services for this group.A step for the betterment of the society.

To specify the topic stroke, we will further move into a type of stroke which is Ischemic Stroke.

 

  • Ischemic is a is a restriction in blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive).

 

It is very essential to provide brain cell oxygenated blood to function other organs properly.A stroke can cause to any nearby person, relative or family member because it not an inherited disease which gives a person to be precautioned about. An Ischemic stroke can not only temporarily give symptoms like but it can also give the body permanent physical disabilities.

Symptoms like-

  • Numbness or weakness in your face, arm, or leg, especially on one side
  • Confusion or trouble understanding other people
  • Difficulty speaking
  • Trouble seeing with one or both eyes
  • Problems walking or staying balanced or coordinated
  • Dizziness
  • Severe headache that comes on for no reason

After observing Symptoms mentioned above, you clearly need to provide medical emergency to the person facing a Stroke.Medical Facilities have a lot of way to diagnose the type of stroke occured. To Identify an Ischemic Stroke they use facility such as 

  • Electrocardiogram (ECG). An electrocardiogram records electrical signals as they travel through your heart. An ECG can often reveal evidence of a previous heart attack or one that’s in progress.

  • Echo-cardiogram. An echo-cardiogram uses sound waves to produce images of your heart. During an echo-cardiogram, your doctor can determine whether all parts of the heart wall are contributing normally to your heart’s pumping activity.After diagnosing the kind of Stroke, To specify if the stroke is Ischemic the treatment which will be implemented will be 
  • Laser surgery: This involves making several tiny holes in the heart muscle, which encourage the formation of new blood vessels.
  • Coronary bypass surgery: The surgeon uses a blood vessel from another part of the body to create a graft that can bypass the blocked artery. The graft may come from the leg or an inner chest-wall artery.
  • Angioplasty and stent placement: A catheter is inserted into the narrowed part of the artery. A deflated balloon is passed through the catheter to the affected area. When the balloon is inflated, it compresses the fatty deposits against the artery walls. A stent, or mesh tube, may left in the artery to help keep it open.

 

 

 

In rare cases when the heart is severely damaged ,could not manage the functioning of pumping the blood throughout the body ,or medicine is not effective a heart transplant may be needed.

A heart transplant involves replacing a heart that is damaged or is not working properly with a healthy donor heart. 

Transplantation can affect in various way, such as ethical, social, economic, political, cultural or geographical in terms of economic because of the financial stability which is to be required for the capability of treatment, and being able to accept heat from a voluntary donor.Cultural and social role, as many members in the community may or may not accept the ideology of transplanting heart from a strange person.

CAS Experience #3: creating a landscape animation in Blender

For my third CAS Creativty Experience, I have created a surreal landscape and animated it using waves and distortion in Blender. I have gone through many tutorials to learn how to create this effect, and ultimately i have created my own animation. Learning outcome 1: I have learned to create stunning effects in graphics engine […]

CAS Experience #2 : Unity Game Development tutorial

LO1: I have completed a tutorial available on the Unity website, https://learn.unity.com/project/john-lemon-s-haunted-jaunt-3d-beginner?uv=2019.4 I have no interest in playing games, but creating them and coding everything is interesting and very stress-relieving for me, therefore i decided to learn Unity, starting with this tutorial LO2: I had a good experience with this tutorial, but I was certainly […]

Description

I have always been very fond of mathematics and programming, and was looking for ways to integrate them; During this exploration, I came across a numerical computing language called Matlab, and decided to explore it further in depth, and look at its applications in fields like Deep Learning and Convolutional Neural Networks. Hence, my goals in this experience were to understand the syntax and functions of Matlab commands and their real-life applications.

Learning Outcomes

LO1 – Identify own strengths and develop areas for growth
I identified my strengths and weaknesses in various fields of mathematics and programming, and this awareness of my weaknesses in mathematical fields such as operations on matrices, and in programming fields such as functions and syntaxes, made me more mindful and cognisant of my skills and knowledge, and made me determined to improve my knowledge and skills in these particular fields of mathematics and programming. Therefore, learning and being aware of your strengths and weaknesses is of utmost importance to make significant progress in the field; you must know your areas of improvement thoroughly in order to improve them, and you must know about your strengths in order to avoid wasting time on topics you already have a certain degree of expertise in.
Hence, I do plan on improving my skills in mathematics, in topics such as matrix manipulation, which can benefit me in both my academics (Maths Analysis and Approaches HL) as well as my professional life in the future. Another field of weakness for me is about learning syntaxes of programming languages, and if I had strengthened this earlier, it could have been very helpful in my MYP Personal Project.

LO2 – Demonstrate that challenges have been undertaken, developing new skills in the process
I found many aspects of this experience challenging; from gaining the conceptual knowledge of deep learning, to knowing how to implement it using Matlab. One of the reasons I found this course challenging is that it involved building large amounts of conceptual knowledge in an unfamiliar field, as well as learning new syntaxes and functions in a distinct unknown language to implement this conceptual knowledge to reality. I could relate to some parts of Deep Learning and Convolutional Neural Networks as I had done an earlier course on Machine Learning, but the majority of the concepts covered were new to me. I overcame this challenge by researching more through Youtube videos, and practising Matlab commands and functions on my own.
I feel a sense of accomplishment and pride over the fact that I successfully undertook and completed this challenge, as challenges help you to develop and practise not only new skills, but develop as a human as well, as it increases your grasping power and will power, and makes it easier to learn new skills in the future. For example, through this challenge, I gained new skills in Matlab and numerical computing, which will most likely help me in my further education as well as in my future profession.
Learning new skills is important not only in education/profession, but in life as well, as it helps you gain new and knowledge-based perspectives on various things, and increases your grasping power, allowing you to learn skills even faster.

LO4 – Show commitment to and perseverance in CAS experiences
As stated before, this experience used a lot of rigorous conceptual knowledge, and also required me to learn new syntaxes and functions in a new language, which required serious commitment and perseverance to learn and practise. This increased my sense of accomplishment, as I was mindful of the efforts I put in.
This experience required a serious commitment of time to complete. This was a little difficult for me, as I have frequently observed that I tend to forget about and lose commitment of projects I undertake, and hence, this experience has taught me the value of persistence and perseverance in the face of challenges, as that will lead to personal and professional growth.
Therefore, perseverance and commitment are very valuable, as they are required for high-quality performance in all fields of life, and are also essential in learning and research.

Final Takeaways

I have demonstrated various Learner Profile Attributes during this experience:

  • Knowledgeable – I applied my knowledge of programming languages and maths to learn the syntax and applications of Matlab much more effectively.
  • Thinker – I used my critical thinking skills to choose the appropriate Matlab functions for each context, and apply the appropriate algorithm and neural network for
  • Reflective – I assessed and evaluated my strengths and weaknesses regularly during the course to try to improve on my learning process of the language as well as the concepts.

I enjoyed this activity thoroughly, and completing it successfully. This gives me a sense of accomplishment and enjoyment. This experience was related to two of my IBDP subjects; namely ITGS and Maths AA, as Matlab combines mathematics with programming, and this experience also focused on real-life implications like Deep Learning and its impact.
Though this experience has not led to significant changes in perspective, I learnt many things from this experience. Firstly, I learnt about the actual contents of the course itself; the syntaxes and functions of Matlab commands, conceptual knowledge of deep learning and convolutional neural networks, and how to implement them in real-life scenarios with Matlab. Secondly, I also learnt many secondary skills, such as mathematical skills associated with neural networks, like matrices, vectors, etcetera. Thirdly, I learnt about values, such as the value of perseverance, and its impact on life.
If I were to do this activity again, I would pick courses that are balanced between theory and practice, and I would research Matlab commands and the mathematics beforehand so that I can take in as much of the knowledge as possible without being restricted by my knowledge of maths/Matlab, allowing me to learn more efficiently.
The experience I completed has a lot of real-life implications, and is a very relevant and upcoming field in the future, and hence, by studying these concepts, I can take this learning forward and apply it in newer technologies like self-driving cars, image detection software, etcetera.
There are ethical issues that may arise from this, such as mass surveillance and tracking through facial recognition, image censorship, etcetera, and thinking about this has helped me become more principled as an IB learner, as I can now engage with these issues on a much deeper, knowledge-based level.
