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.

Abstract

Background: it is essential to have an understanding of life expectancy and risk factors among patients with sickle cell disease (sickle cell anemia, hemoglobin diseases, and thalassemias). These are required to counsel the patients, target treatment, and plan the right clinical trials.

 

Methods: a research followed 3764 people ranging from birth to 66 years of age and suffering from scd. The procedure was done to understand the life expectancy and calculate the average age at death. Moreover, the study understood the reasons for the death in all 209 adults. It used the proportional-hazards regression analysis to know the risks for an untimely death in adults with sickle cell anemia.

 ;

Results: when the results for young kids and adults with sickle cell anemia were observed, it was found that the average age at death was 48 for women and 42 for men. Moreover, suffering from hemoglobin c disease had an average mortality age of 60 for men and 68 years for women.

 

In people with sickle cell disease, 18% of deaths took place in patients with mainly renal organ failures. 33% of the tested patients were medically free of organ failures but episodes of pain crisis took their life. Out of these patients, 78% experienced chronic pain, chest syndrome, or both, while 22% suffered a stroke that took their lives.

 ;

Clinical modeling showed that people with sickle cell anemia faced acute chest syndrome, seizures, kidney failure, a white-cell count of over 15, 000 per cubic mm, and a low hemoglobin level were related to a risk of early death.

 

Conclusions: results suggested that 50% of patients with sickle cell anemia lived beyond the age of 50. A huge share of those who lost their lives suffered no noticeable chronic organ failure. However, most of them died due to acute episodes of pain or stroke. Early death was seen highest among patients who had symptomatic disease. High levels of fetal hemoglobin suggested improved chances of survival and are assumably a credible source to foresee the risks and other factors related to adult life expectancy.

Life Expectancy And Risk Factors Involved In Sickle Cell Disease

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?

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

Congestive heart failure is a condition when your heart stops pumping blood effectively. By being aware of the risk factors, you can manage your condition in a better way. Also, you must consult your doctor on a regular basis to get yourself checked.

Complications Associated With Congestive Heart Failure

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
