Your Answer Is Correct

Your Answer Is Wrong

Explanation :

Context: On 14th October, 2020, Union Ministry for Health and Family Welfare launched the second phase of "Thalassemia BalSewaYojna" for the underprivileged Thalassemic patients.

Explanation:

About Thalassemia

It is a blood disorder passed down through families (inherited) in which the body makes an abnormal form or inadequate amount of hemoglobin.
(Hemoglobin is the protein in red blood cells that carries oxygen).
The disorder results in large numbers of red blood cells being destroyed, which leads to anemia.
(Anemia is a condition in which our body doesn’t have enough normal, healthy red blood cells).

Types

Alpha thalassemia occurs when a gene or genes related to the alpha globin protein are missing or changed (mutated). It occurs most often in people from Southeast Asia, the Middle East, China, and in those of African descent.
Beta thalassemia occurs when similar gene defects affect production of the beta globin protein.It occurs most often in people of Mediterranean origin. To a lesser extent, Chinese, other Asians, and African Americans can be affected.

Thalassemia BalSewaYojna

Launched in 2017, this scheme is a Coal India CSR funded Hematopoietic Stem Cell Transplantation (HSCT) program.
It aims to provide a one-time cure opportunity for Haemoglobinopathies like Thalassaemia and Sickle Cell Disease for patients who have a matched family donor.

Eye Related Disorders

Consider the following statements:

Myopia is a common vision condition in which one can see objects near to him clearly, but objects farther away are blurry.
Presbyopia occurs when your eyes gradually lose the ability to see things clearly up close.
In Hypermetropia the image of a nearby object is formed behind the retina. This means that light is focused too far back in the eye, causing things which are close up to appear blurred.

Which of the statement(s) given above is/are correct? Choose the correct answer from the codes given below:

	A	Only 1

	B	2 and 3

	C	Only 3

	D	1, 2 and 3

Your Ans is

Right ans is D

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

Myopia

Myopia is the term used to define being shortsighted.
A myopic person has clear vision when looking at objects close to them, but distant objects will appear blurred. This is because light is focused in front of the retina and, being too far forward in the eye, things in the distance look blurred.

Presbyopia

It occurs when your eyes gradually lose the ability to see things clearly up close. It is a normal part of aging.

Hypermetropia

Sometimes called hyperopia, is the term used to define being longsighted.
If one is hypermetropic, the image of a nearby object is formed behind the retina. This means that light is focused too far back in the eye, causing things which are close up to appear blurred.

Measles

Consider the following statements:

Your Ans is

Right ans is B

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

Measles, also known as morbilli, rubeola, red measles, and English measles is a highly contagious infectious disease caused by measles virus.
Measles morbillivirus, formerly called measles virus (MeV), is a single-stranded, negative-sense, enveloped, non-segmented RNA virus of the genus Morbillivirus within the family Paramyxoviridae.
Humans are the natural hosts of the virus; no animal reservoirs are known to exist.
Measles is an airborne disease which spreads easily through the coughs and sneezes of infected people.
It may also be spread through direct contact with mouth or nasal secretions.

Symptoms

The first sign of measles is usually a high fever, which begins about 10 to 12 days after exposure to the virus, and lasts 4 to 7 days.
A runny nose, a cough, red and watery eyes, and small white spots inside the cheeks can develop in the initial stage.
Koplik's spots seen inside the mouth are diagnostic for measles, but are temporary and therefore rarely seen.
These are small white spots that are commonly seen on the inside of the cheeks opposite the molars.

Reproduction Number

Consider the following statements:

Reproduction number (R0) indicates the average number of people who will contract the virus from a person who has already been infected, in a population that does not have immunity for the said disease.
R0 is the division of the number of new infections by the number of existing infections, or the average number of new infections over an infectious period (R0= new infections/existing infections).

Choose the correct answer from the codes given below:

	A	Only 1

	B	Only 2

	C	Both 1 and 2

	D	Neither 1 nor 2

Your Ans is

Right ans is C

Your Answer Is Correct

Your Answer Is Wrong

Explanation :

Also called the basic reproduction number, it indicates the average number of people who will contract the virus from a person who has already been infected, in a population that does not have immunity for the said disease.
R0 is the division of the number of new infections by the number of existing infections, or the average number of new infections over an infectious period (R0= new infections/existing infections).
To illustrate with an example, if the number of people diagnosed with a disease increases from four to eight in two days, it is likely to increase to 16 two days later, or in four days from the start. This makes the R0 two.

R0 Values

Three possibilities exist for the potential spread or decline of a disease, depending on its R0 value:

If R0 is less than 1, each existing infection causes less than one new infection. In this case, the disease will decline and eventually die out.
If R0 equals 1, each existing infection causes one new infection. The disease will stay alive and stable, but there won’t be an outbreak or an epidemic.
If R0 is more than 1, each existing infection causes more than one new infection. The disease will spread between people, and there may be an outbreak or epidemic.
The higher the R0, the more contagious the infection.

Your Answer Is Wrong

Explanation :

Huntington’s disease, also known as Huntington's chorea, is a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain.
It deteriorates a person’s physical and mental abilities usually during their prime working years and has no cure.
It is known as the quintessential family disease because every child of a parent with HD has a 50/50 chance of inheriting the faulty gene.

Cause

It is caused by an expansion of a repeating CAG triplet series in the hunting in gene on chromosome 4, which results in a protein with an abnormally long polyglutamine sequence.

Symptoms

Personality changes, mood swings & depression
Forgetfulness & impaired judgment
Unsteady gait & involuntary movements (chorea)
Slurred speech, difficulty in swallowing & significant weight loss

Treatment

There is currently no cure for Huntington's disease and no way to slow or stop the brain changes it causes. Treatments focus on managing symptoms.
