Rashtrapati Bhavan

Rashtrapati Bhavan, India Gate and other important central government monuments and buildings like North block and South block were illuminated with red light on 30 October to raise awareness of the people about dyslexia.

Every year October month is observed as the International Dyslexia awareness month in the world. Since 2019, Go Red for Dyslexia has helped spread awareness for dyslexia across the globe by encouraging people to turn anything and everything red.

Go Red for Dyslexia is a global campaign supported by Succeed with Dyslexia organisation.

 What is Dyslexia ?

Dyslexia is a brain-based type of learning disability that specifically impairs a person's ability to read. People with dyslexia have trouble matching the letters they see on the page with the sounds those letters and combinations of letters make.

While people with dyslexia are slow readers, they are often, paradoxically, very fast and creative thinkers with strong reasoning abilities.

Dyslexia can be inherited in some families, and recent studies have identified a number of genes that may predispose an individual to developing dyslexia.

pathogen reduction machine

Uttar Pradesh Chief Minister Yogi Adityanath inaugurated Asia’s first pathogen reduction machine at the King George's Medical University (KGMU) in Lucknow. He was accompanied by Deputy Chief Minister Brajesh Pathak, State minister Mayankeshwar Sharan and Professor Bipin Puri, Vice Chancellor of King George's Medical University. The Chief Minister also inaugurated the KGMU’s Department of Thoracic Surgery and Vascular Surgery.

What is a Pathogen? 

  • The pathogens is an organism which can cause disease to its host body.   It could be viruses, bacteria, fungi, protozoa, parasites.
  • Pathogens cause illness to their hosts through a variety of ways. It directly damages the tissues or cells of the host  during replication,
  • However, sometimes due to a strong or excessive immune response from the host body, the body itself kills infected and uninfected cells and damages host tissues. 

Need of cleaning transfused blood of pathogens 

  • Blood transfusions are needed in procedures ranging from surgery to delivery and transplant. Blood transfusion is always done after all the necessary blood tests are done. But despite this, some impurities like pathogens remain in the blood, due to which reactions or side effects can be seen in recipient patients. 
  • This machine helps in eliminating any type of pathogens in the donor's blood which will prove to be very beneficial for organ transplant or patients with weak immunity.
  • The machine is capable of completely purifying the blood unit by removing all types of bacteria from the blood within 10-15 minutes through the ultraviolet immunometer.

TB patients increases worldwide

According to a World Health Organisation (WHO) report “Global Tuberculosis Report 2022” released on 27 October 2022, the incidence of Tuberculosis (TB) patients worldwide has shown an increasing trend reversing a 20 year trend of decline due to covid pandemic.

According to the WHO a total of 16 lakh people died from TB in 2021 which is an increase of 14% as compared to 2019. In 2019 14 lakh people died due to TB while in 2020 it was 15 lakhs. 

The WHO says that due to the ongoing war in different parts of the world, the global energy crisis and the food crisis, the situation of TB may worsen in the coming times. “The first priority should be to restore patient access to TB related services so that the detection and treatment of TB cases can be brought back to 2019 levels,” the report says.

Main Highlights of the WHO Report

  • TB is the 13th leading cause of death and the second leading infectious killer after COVID-19.
  • About 10 million people became ill with TB in 2021, which is 4.5 percent more than in 2020.
  • An estimated 66 million lives were saved through TB diagnosis and treatment between 2000 and 2020.
  • Globally, TB incidence is falling at about 2% per year and between 2015 and 2020 the cumulative reduction was 11%. 
  • Ending the TB epidemic by 2030 is among the health targets of the United Nations Sustainable Development Goals (SDGs).
  • In 2021, the largest number of new TB cases occurred in the South-East Asian Region, with 46% of new cases, followed by the WHO African Region, with 23% of new cases and the WHO Western Pacific with 18%.

India leads the New TB cases 

According to the WHO, in 2020, 87% of new TB cases occurred in the 30 high TB burden countries. Eight countries accounted for more than two thirds of the global total. 

Maximum new cases were reported from India and followed by, Indonesia, China, the Philippines, Pakistan, Nigeria, Bangladesh and the Democratic Republic of the Congo.

TB related Deaths 

India ranks first among the four countries that have the highest number of TB related deaths. It is followed by Indonesia, Myanmar and the Philippines. 

The report says that it is possible that TB will once again be the number one cause of death in the world. Last year it was covid -19. 

What is TB? 

Tuberculosis (TB) is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. Tuberculosis is curable and preventable.

TB is spread from person to person through the air. When people with lung TB cough, sneeze or spit, they propel the TB germs into the air. A person needs to inhale only a few of these germs to become infected.

India and TB

The government has set a target to eliminate TB from India by 2025.

Every year March 24 is observed as World Tuberculosis Day in the world.

ISRO launches

The Indian Space Research Organisation (ISRO) has successfully launched its heaviest rocket LVM3-M2, from the Satish Dhawan Space Centre in Sriharikota spaceport, Andhra Pradesh on 23 October 2022. The mission, which was named LVM3-M2/OneWeb India-1, carried 36 broadband communication satellites of OneWeb Company.

It was the first commercial launch of the GSLV Mk3 now called LVM3 (Launch Vehicle Mark 3). M2 means that it is the second mission of the rocket.

The launch was part of the contract between OneWeb, a London-based company, and NewSpace India Limited (NSIL), a central public sector enterprise under the Department of Space, to launch One Web LEO satellite launches on board ISRO's LVM3.

Satellite carried by the Rocket 

It carried 36 broadband communication satellites of the United Kingdom based company OneWeb. OneWeb is a private satellite communications company, in which India's Bharti Enterprises (Airtel) is a major investor and shareholder.

The satellites were later successfully placed in the Low Earth Orbit (LEO). 

The company’s constellation of satellites will be used to beam internet connectivity to terrestrial regions, in a service that will compete with Elon Musk-backed Starlink by SpaceX, Jeff Bezos-backed Project Kuiper.

LVM3-M2 Rocket 

The LVM3-M2 is a three-stage launch vehicle that has two strap-on solid propellant stages (S200) on its sides and a core stage that consists of an L110 liquid stage and a C25 cryogenic stage. 

The rocket was earlier called GSLV (Geosynchronous Satellite Launch Vehicle) MkIII and ISRO had successfully carried out four missions.

The current rocket has the ability to launch 8 tonnes satellite into the LEO and satellites weighing up to 4,000 kg into Geosynchronous Transfer Orbit (GTO)

What is LEO? 

A low Earth orbit (LEO) is an orbit that is relatively close to Earth’s surface. It is normally at an altitude of 2000 km but could be as low as 160 km above Earth. The satellite placed in this orbit is used for communication, spying, remote sensing etc.
