Blood is one of the most crucial elements of human existence. It works as a commute for oxygen and various nutrients in reaching the cells. These functions make blood a vital source for the body to operate. That said, india needs 38, 000 blood donations every day, which adds up to 5 crore units required in a year. However, only 2.5 crore units are available against the huge unfulfilled numbers. Hence, it is essential to recognize the importance of blood donation.

 

Why is blood donation important?

While blood donations are essential to help people with surgeries, they are equally vital during cancer treatments, chronic diseases, and gruesome injuries. Moreover, they also benefit the donors in a significant way.

 ;

Types of blood donations

Blood donations are of several types through which a single donor has the potential to help nearly three people.

 

Whole blood donation

It is the most common process of donating blood. One pint of blood collected supports numerous patients in the process. It is, then, divided into different components that aid the donation.

 ;

Plasma donation

The process of plasma collection is carried out through a method called apheresis. It divides plasma from other blood components. Its blood clotting abilities help trauma patients and people undergoing cancer treatment.

 

Platelet donation

The collection of platelets is also done using apheresis. Once identified in the donor s blood, the rbcs and the donor gets other fluids back. Cancer patients are the chief beneficiaries of platelets as they play a prominent role during cancer treatments.

 ;

Double red cell donation

Red blood cells are also collected through the apheresis process. It helps donors to donate twice the dose of a whole blood donation. One can help a patient suffering from blood loss using this method.

 

Advantages of blood donation

Blood donations have several advantages that people should know. They help fight many severe health conditions in the human body. Some of them include-


	
	Loss of blood due to internal or external injuries caused by accidents
	
	
	Sickle cell disease or other abnormalities that affect the blood
	
	
	In the treatment of cancer
	
	
	Cardiovascular or orthopedic surgeries
	
	
	Blood disorders
	
	
	Transplant processes
	
	
	Treatments involving plasma
	


 ;

Covid-19

According to food and drug administration (fda) reports, patients who have recovered from covid-19 can help others by donating blood plasma. They contain antibodies that fight the infection, helping their body fight the virus.

 

Benefits for the donor

Even the donors receive many health and social benefits because of blood donation. Where donated blood saves lives, experts suggest that donors can also benefit from the same. Some of these advantages include:

 ;


	
	Boosting cardiovascular health
	
	
	Maintaining blood pressure
	
	
	Contributing to the community
	
	
	Reducing the iron levels
	
	
	Improving overall health
	



 

Why Blood Donation Is Important?

When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. There are various types of brain tumours that exist. Some of the brain tumours which exist are malignant or cancerous while other may be non-cancerous. A brain tumour can begin in any part of the brain and spread to other parts of the body or vice-versa. The growth rate of brain tumours is different for each individual suffering from it. As per studies, every 2 in 1, 00, 000 people are said to be affected by a brain tumour in india. However, it may come as a relief to some as not all brain tumours are cancerous or life-threatening. Some are benign tumours and seldom pose any threat to the affected individual.

 

Types of brain tumor

Brain tumours may be primary or secondary.

Primary brain tumour

In this type of brain tumour, the abnormal mass of cells that originated in the brain does not metastasize to the other organs. Based on their location in the brain, the primary brain tumours may be of the following types.


	
	Gliomas: one of the most common types of primary brain tumours, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include astrocytomas (originates in the cerebrum of the brain), glioblastomas (these tumours form from the astrocytes which form the supportive tissues of the brain), ependymoma (these develop from the ependymal cells which are present within the cns), oligodendrogliomas (these tumours are found to arise from the oligodendrocytes).
	
	
	Schwannomas: also called acoustic neuromas, these primary brain tumours form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
	
	
	Meningiomas: these types of tumours are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
	
	
	Primitive neuroectodermal tumours (pnets): primitive neuroectodermal tumours (pnets) are rare malignant tumours that originate from the fetal (embryonic) cells in the brain.
	
	
	Pituitary adenomas: as the name suggests, these tumours arise from the pituitary gland located at the base of the brain.
	
	
	Medulloblastomas: common among children, these malignant primary tumours develop in the brain (lower back) and gradually spread via the spinal fluid.
	


Other types of primary brain tumours include craniopharyngiomas and germ cell tumours.

Secondary brain tumours ;

Unlike the primary brain tumours, these tumours have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. Secondary brain tumours are found to be more common.

 

What Are The Different Types Of Brain Tumours?

A brain tumor is a common scenario these days. With around 40, 000 to 50, 000 cases per year, india has seen exponential growth in the numbers. However, understanding that brain tumors can be prevented or treated in various ways is important. Early detection of the tumor makes treatment and surgery easier and more effective. Signs usually include headaches, nausea, vomiting, facial paralysis, and sleep disturbance.

There are numerous myths and misconceptions among the general public about brain tumors. This leads to delays in seeking treatment. Some popular myths and facts about brain tumors are-

Myth: everyone has the same type of brain tumor

Fact: over 120 types of brain tumors are detected to date. They are differentiated based on the size, cell of origin, location, and grade of tumors.

Myth: everyone with a brain tumor has similar symptoms

Fact: not all persons show the same symptoms. They can have diverse signs depending on the condition. Some may even have seizures.

Myth: all tumors are cancerous in nature.

Fact: while not all tumors are cancerous in nature, brain tumors can be cancerous or benign depending on the condition.

Myth: only old people are susceptible to brain tumors

Fact: brain tumors can happen to people of any age. Moreover, some tumors are relatively more common in young adults. Brain tumors like medulloblastoma can also appear in children. Most lethal brain tumors like  glioblastoma mutiformae  can develop in adolescents and old people.

Myth: lifestyle modification can keep brain tumors away.

Fact: lifestyle changes have no role in preventing brain tumors. However, a workout, a nutrient-rich diet with high fiber content, and no smoking, no tobacco or alcohol consumption are good for overall health.

Myth: brain tumors are genetic.

Fact: it is not true that if no one in the family had a tumor, even you can t. Genetic mutations are too few to cause cancer. 90- 95% of cancer is by mutations that develop during an individual s life.

Myth: life gets back to normal as soon as the treatment is done in a patient.

Fact: benign tumors rarely recur. However, the cancerous tumors may recur posing a challenge to the doctor and the patient.

 

Myths And Facts Associated With Brain Tumour

People with sickle cell disease often experience myriad symptoms of the disease that can be controlled by the right nutrition. Reports suggest that nutrition is an increasingly significant factor to prevent symptoms such as slow growth, lower body mass, joint issues, infections, pain crises, and anemia.

There is a greater than the typical requirement for both calories and micronutrients.

The nutritional requirement of a sickle cell patient emphasizes more on vegetables, fruits, whole grains, and more similar food items. These can prevent any deficiencies in the body and also decrease any chances of disease exacerbation.

 


	
	High-calorie nutrient-dense diet
	


The usual energy intake in a sickle cell patient is normally lower than the average values. It is a case even when the condition is asymptomatic where the requirement drops to half the level. As a result, people with sickle cell diseases (especially kids) are at higher risk for impaired growth and considerably lesser fat and fat-free mass, with obesity also posing a risk. It is suggested to have adequate energy supplements in the diet to reach the minimum sufficient requirement of the body that can be done only by proper nutritional assessment.


	
	Adequate fluids
	


Avoiding dehydration is another significant factor to avoid any severe symptoms of sickle cell disease. Sickling of the erythrocytes aggravates in patients who perform hardcore physical work in the heat without drinking enough fluids. This leads to dehydration and can even result in constipation.


	
	Micronutrients
	


Micronutrient deficiencies can be found in sickle cell patients up to a great extent. Several vitamins and minerals like vitamin a, b6, c, e, carotenoids, zinc, and magnesium are often found in fewer numbers in scd patients. A significant drop in blood-antioxidant status may result in acute chest syndrome. The supplementation of these vitamins and minerals can reduce the number of sickled cells in the body. Plant phenols and flavonoids may also help in lowering oxidative stress.


	
	Calcium-rich food
	


Getting plenty of calcium-rich food like dairy products, leafy vegetables, cereals, and fruit juices aids the child's growth and development. This may lead to a stronger physical structure and a greater resistance to the disease.


	
	Omega-3 fatty acid
	


There are reduced proportions of omega-3 polyunsaturated fatty acids in sickle cell patients. These acids aid the fluidity of red blood cell membranes. As a result, they prevent sickle cell crises. Supplemental docosahexaenoic (dha) and eicosapentaenoic (epa) have shown numerous therapeutic benefits in scd patients.

Role Of Nutrition In Sickle Cell Disease

People suffering from sickle cell disease (scd) usually start showing symptoms very early. They can appear to show up even during the first year of life. Symptoms of a sickle cell vary from one person to another and can be mild to serious depending on the condition.

 

Sickle cell disease is a health condition that worsens with time. Despite the absence of any full-proof solution, some treatments prevent further complications. These treatments can help patients receive aid for a lifetime. Simply said, sickle cell diseases can be managed medically.

 ;

Treatment

Treatment in a sickle cell patient depends on the severity of the symptoms. Preventing complications and relieving pain is the primary aim of the diagnosis. They can range from medications to blood transfusions.

 

Concerns

Some of the concerns that need to be taken care of during the treatment of scd are-

 ;


	
	Prevent painful scenarios
	


A painful episode or sickle cell crisis can be avoided by consuming sufficient fluids, wearing warm clothing, and staying away from sudden temperature changes.

 


	
	Avoid infections
	


Children with sickle cell anemia are made safe from infections by using penicillin. Adults with anemia might need to take penicillin all their lives. Doctors should ensure that all vaccinations in children and adults are periodically done to avoid any infections. However, during the covid-19 pandemic sickle cell patients should take extra care.

 ;

Medications

While there can be numerous ways to manage sickle cell treatment, medications help in a significant way. Some of the prescribed medicines are-


	
	Hydroxyurea- it reduces the frequency of sickle crises. Pregnant women should stay away from this according to experts.
	
	
	Crizanlizumab- this drug injected into the patient can help reduce the sickle crises in adults and children over the age of 16.
	
	
	Voxelotor- it is an oral drug used in children over 12. It lowers the risk of anemia by improving blood flow.
	
	
	Pain-relievers- narcotics to prevent excessive pain can also be used during the treatment.
	


 

Surgical procedures


	
	Blood transfusion
	


It is used to prevent stroke and other related complications in patients. This can increase the number of red blood cells in the body that can help reduce the symptoms.

 ;


	
	Stem cell transplant
	


It is also called a bone marrow transplant and is used to replace affected bone marrow with a healthy one. This procedure is carried out between matched donor and recipient. Although it is a known cure for sickle cell disease, various risks involved make it a less used practice.

 

Can Sickle Cell Be Cured?

Atherosclerosis refers to a medical condition in which the arteries become hardened and narrowed due to the accumulation of cholesterol plaque in the walls of the artery, obstructing the flow of blood.

What are the causes?

Atherosclerosis is a slow but progressive disorder that starts with the damage of endothelium   cells lining the interior surface of lymphatic and blood vessels. This allows bad ldl cholesterol to build up in the artery walls. Over time, a plaque made of calcium, macrophages, and cholesterol grows to a certain size to clog up arteries, disrupting blood flow around the body.

Other factors leading to atherosclerosis to include  

High blood pressure

High levels of triglyceride in the blood

High cholesterol levels

Certain medical conditions   diabetes, obesity, insulin resistance

Smoking/use of tobacco

Inflammatory conditions like lupus and arthritis

Symptoms of atherosclerosis

Atherosclerosis may develop in childhood or during adolescence. Mild conditions may not reveal observable symptoms unless the arteries are clogged, and blood supply to the tissues and organs are restricted.

Signs of moderate to severe atherosclerosis depend on the affected arteries   it could be the arteries leading to your brain, your heart, legs and arms, or the kidney. The symptoms of atherosclerosis include  

Weakness and fatigue

Difficulty breathing/concentrating

Headaches

Facial numbness

Paralysis

Vomiting

Chest pain

Anxiety

Loss of appetite

Swelling in the feet and hands

If any of the above symptoms seem familiar to you, consult a doctor right away for treatment.

Can atherosclerosis be prevented?

The best way to avoid cholesterol plaque from building up in the artery walls is to prevent the onset of atherosclerosis with these preventive measures.

Eat healthy   avoid eating foods that are rich in saturated fats   red meat, butter and cheese. These increase your cholesterol levels drastically. Instead, include foods that contain unsaturated fats, like avocados, olive oil, fatty fish, nuts and seeds because these help to keep ldl or bad cholesterol levels down.

Stay active   exercising and staying active can help regulate your cholesterol levels and prevent certain conditions that might put you at risk for atherosclerosis.

Quit smoking   people who smoke should quit smoking because it is a major risk factor for atherosclerosis   it increases blood pressure, which in turn, affects your cholesterol levels.

Atherosclerosis can lead to complications. With precautionary measures and proper treatment, the condition can be avoided.
