The world celebrates world blood donor day on the 14th of june to raise awareness of the need for safe blood and blood products and to thank voluntary and unpaid blood donors for their life-saving gift of blood. 

Importance of blood donation

The importance of donating blood is not only to save the lives of thousands of people who are deprived of life but also to save the lives of many more who are affected by the various diseases. ;

 

It has also been seen that when people; e have donated their blood, they have gained many health benefits as it helps in weight loss, helps maintain healthy liver and iron levels, it helps reduce the risk of heart attack and cancer. ;

 

A blood donation can save a life of- ;


	
	Victims of natural disasters, including earthquakes
	
	
	Patients with hemophilia, sickle cell disease, or cancer
	
	
	People who suffer traumatic injuries from being in a car accident
	
	
	Surgery patients
	
	
	Shooting or stabbing victims
	
	
	Women who suffer complications during childbirth
	


 

Blood types that are needed most

It s good to donate if you re healthy. However, there s always a need for specific blood and plasma which are universal and can be used when a patient blood type is unknown. For newborn infants or if a patient's particular blood type is unavailable.

 ;


	
	Type o negative blood is always needed because it can be used in patients regardless of their blood type.
	
	
	Type ab positive plasma can also be transfused to patients with other blood types. 
	


 ;

Donations are constantly needed

Because of their short shelf life of 5 days after being collected, platelet donations are constantly by the blood blank. Red blood cells also have a short shelf life and needed to be used within 42 days after the collection. Cryoprecipitate and plasma can be frozen and stored for up to a year after donation.


 

Some misconceptions about blood donations


	
	The donor will not experience any kind of pain while donating. ;
	
	
	There will be no scarcity of blood in the body after donating the blood as even after the donation the body will have a surplus quantity of blood. 
	
	
	The common misconception everyone has is that they will faint after donating their blood. ;
	
	
	You will be able to resume your everyday activity immediately after donating the blood. 
	
	
	You will not get infected with aids if you donate your blood. ;
	


 

Donating blood is a great way to give back to your community and potentially save a life by only giving up an hour of your time.

World Blood Donor Day: How Can We Save Life By Donating Blood?

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.

Potassium is an essential mineral that helps in healthy functioning of your body   it helps in muscle contractions, fluid balance, and nerve signals. Your body receives the required amount of potassium from specific food sources and processes the same. The excess potassium is eliminated from the bloodstream by your kidneys.

Under normal circumstances, your blood levels should be between 3.5meq/l and 5.5meq/l for potassium to carry on these functions. Healthy kidneys play a vital role in keeping the potassium levels in check.

In case your kidneys are unable to remove excess potassium, it may get stored in your blood, leading to a condition known as hyperkalemia.

The link between your kidneys and potassium

The mineral potassium and your kidneys share an intricate relationship. If the levels of potassium in your blood are too high, it can pose a threat to your cardiac condition   leading to a ;heart attack or ;irregular heartbeat.

Hyperkalemia occurs when the kidneys fail to function properly. Your kidneys work to balance the amount of potassium consumed with that, which is eliminated through urine. Your body takes in potassium through the foods and drinks you consume. In the initial stages of your kidney disorder, they may be able to make up for high levels of potassium. However, as your condition worsens, they may be unable to eliminate enough of the mineral from the body.

How to find out if you have high potassium levels

The only way to figure out if your potassium levels are healthy or too elevated is to go for a blood test. The test measures the level of potassium in the bloodstream.

As long as your kidneys are healthy, your potassium levels will be under control. Therefore, if you have hyperkalemia, or if there are chances of you getting it, you may have to cut back on foods that are high in potassium content. Besides, you will have to rely on diuretics and potassium binders.

World environment day is celebrated annually on 5th june. This day encourages awareness and action for the protection of our environment. It raises the problems facing our environment such as plastic pollution, air pollution, illegal wildlife trade, sea-level increase, sustainable consumption, and food security, among others. 

 ;

World environment day is a reminder for us to pause and reflect on our actions and their subsequent consequences on the planet. 

 ;

When was the world environment first celebrated?

The day was first observed in 1974 in the city of spokane in the usa.

 

History of world environment day (wed)

1972- the un general assembly established world environment day on the 1st day of the stockholm conference on the human environment. ;

1974- the first" world environment day" was held with the theme" only one earth. 

1987- the idea for rotating the center of these activities by selecting different host countries began. ;

 

Why is world environment day celebrated? ;

For a healthy life, the environment plays an important role. It provides us with air, food, etc. The environment is like our neighborhood, its surrounding conditions affect us and also modify development. It is really necessary to address the environmental issues like deforestation, increasing global warming, pollution, wastage and losses of food, etc. Currently, our earth is experiencing a triple planetary emergency: 


	
	Pollution is poisoning our air, land and water. ;
	
	
	Climate is heating up too quickly
	
	
	Habitat loss
	


The deteriorating environmental conditions worldwide had already raised alarms in academic circles, among scholars studying its conditions. However, general masses seemed oblivious to changes that were not directly affecting them.

The world environment day is structured in a manner that allows one country to take up the responsibility of selecting the theme and hosting the key celebrations each year. 

Let's all come together and ensure this unique and beautiful planet remains a comfortable home for humanity.

World Environment Day: What Is World Environment Day And Why It Is Celebrated? 

What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.

Urinary tract infections (uti) can occur anywhere in the urinary system   the bladder, kidneys, urethra, and ureter. Most of these infections affect the lower part of the urinary system   urethra and the bladder.

An infection ;confined to the bladder can be frustrating and painful. You may experience pain during urination, and pus or blood in the urine. However, the condition becomes worse if the infection spreads to the upper part of the urinary system, particularly to the kidneys, triggering nausea, ;vomiting, and severe pain in the back.

If uti is left untreated, it can potentially lead to kidney damage   a condition known as pyelonephritis.

How does untreated uti affect the kidneys?

Untreated urinary tract infections can cause the kidneys to swell up and damage them permanently. The infections initially begin in the lower tract of your urinary system. Then the bacteria slowly enter your body through the urethra and begin multiplying and spreading up to the bladder. The bacteria eventually travel to your kidneys through the ureters.

Some people are at higher risk for kidney damage due to urinary tract infections. This includes  


	
	Pregnant women
	
	
	Elderly people
	
	
	People with kidney problems
	
	
	Someone with a weak immune system
	


Signs to watch out for

An untreated infection in the bladder that has spread to the kidneys is associated with symptoms, such as the following  


	
	Chills and ;fever
	
	
	Vomiting and nausea
	
	
	Pain in either side of your lower back
	


You should visit a doctor right away if you notice the above uti symptoms. The condition requires immediate medical intervention in order to prevent damage to your kidneys.

Symptoms of painful utis can be managed by combining medications and lifestyle remedies. Consult a specialist to diagnose the condition early and seek appropriate treatment to avoid complications.
