  • IFPMA Report on Antimicrobial Resistance

    Why in the news?

    The International Federation of Pharmaceutical Manufacturers and Associations (IFPMA) released a report titled “From Resistance to Resilience: Reinforcing the Response to Antimicrobial Resistance,” emphasizing the urgent need for enhanced Antibiotic development.

    Report Highlights: Current State of Antibiotic Development:

    • Weak Pipeline: The current pipeline for developing new antibiotics is described as weak, fragile, and insufficient against growing antimicrobial resistance.
    • AMR Threat: Recognized by the World Health Organization (WHO) as one of the greatest global health threats, AMR is linked to around 1.2 million direct deaths and 5 million associated deaths annually.

    What is Antimicrobial Resistance (AMR)?

    • Antimicrobials are substances designed to eliminate or suppress the growth of microorganisms.
    • This category encompasses antibiotics, fungicides, antiviral drugs, and agents targeting parasites.
    • AMR occurs when microbes such as bacteria, viruses, parasites, and fungi become resistant to antimicrobial treatments to which they were previously susceptible.
    • Microorganisms that develop resistance to antimicrobials are sometimes referred to as “superbugs”.

    Global Status of AMR

    A recent report from the Global Research on Anti-microbial Resistance (GRAM) project found that:

    • In 2019, an estimated 4.95 million people suffered from at least one drug-resistant infection and AMR directly caused 1.27 million deaths.
    • AMR is one of India’s major public health problems, directly contributing to about 30% of deaths due to neonatal sepsis across India.
    • These are due to multidrug-resistant (MDR) hospital-acquired infections in many cases.
    • 30% of the COVID-19 deaths in India could be attributed to our failure to treat the secondary bacterial infections caused by MDR pathogens with the appropriate antibiotics.

    What are the factors that cause AMR? 

    • Over-prescription of Antibiotics: Frequently prescribing antibiotics for conditions that do not require them, such as viral infections, accelerates the emergence of resistance.
    • Incomplete Treatment Courses: Patients not completing their antibiotic courses as prescribed can leave surviving bacteria that adapt to become resistant.
    • Self-Medication: Individuals using antibiotics without a prescription, especially in regions where they are available over the counter, increases misuse and drives resistance.
    • Lack of New Antibiotics: The slow pace of new antibiotic development fails to keep up with the rate of bacterial evolution, reducing effective treatment options.
    • Hospital Settings: Hospitals are critical hotspots for the spread of resistant infections due to the high use of antibiotics and the concentration of vulnerable patients with open wounds, invasive devices, and weakened immune systems.
    • Global Travel: International travel allows for the rapid spread of resistant mutant strains between communities and across borders.

    India’s efforts to combat AMR:

    Description
    National Action Plan on Antimicrobial Resistance (NAP-AMR)
    • Launched in 2017, this 5-year plan involves multiple ministries to tackle AMR across human, animal, and environmental sectors.
    • Focuses on enhancing awareness, surveillance, infection prevention, optimizing antimicrobial use, promoting research, and fostering international collaborations.
    New Delhi Declaration on AMR
    • Adopted in 2023 at the G20 Summit.
    • It emphasizes strengthening surveillance, regulating antibiotic sales, and boosting research for new treatments and diagnostics in the South-East Asia Region.
    National Anti-Microbial Resistance Research and Surveillance Network
    • Established under the Indian Council of Medical Research to monitor AMR trends through a network of laboratories across India.
    National Programme on Containment of Antimicrobial Resistance
    • Initiated by the Ministry of Health and Family Welfare to enhance AMR surveillance, infection control, and antimicrobial stewardship in healthcare facilities.
    Red Line Campaign
    • Started in 2016, it raises awareness about the irrational use of antibiotics.
    • Medicines marked with a red line on their packaging are prescription-only, aiming to reduce misuse and over-the-counter sales.
    National One Health Program for Prevention and Control of Zoonoses
    • Launched in 2019, this program uses a multi-sectoral approach to strengthen responses to zoonotic diseases, including those caused by antibiotic-resistant pathogens.

  • Understanding Water Loss on Venus

    Why in the News?

    Over four billion years ago, Venus had enough water to potentially cover its surface with an ocean approximately 3 km deep, but today, it would remain with only 3 cm.

    • A research by US scientists explain the Non-Thermal Dissociative Recombination (DR) responsible for faster loss of water from Venus.

    About Venus

    • Venus is the second planet from the Sun. It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth.
    • Venus is notable for having the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulphuric acid cloud cover.
    • At the surface it has a mean temperature of 464 °C (737 K) and a pressure of 92 times that of Earth’s at sea level.
    • These extreme conditions compress carbon dioxide into a supercritical state close to Venus’s surface.
    • Internally, Venus has a core, mantle, and crust. Venus lacks an internal dynamo, and its weak induced magnetosphere is caused by atmospheric interactions with the solar wind.
    • Venus is one of two planets in the Solar System (the other being Mercury), that have no moons.
    • The rotation of Venus has been slowed and turned against its orbital direction (retrograde) by the currents and drag of its atmosphere.
    • It takes 224.7 Earth days for Venus to complete an orbit around the Sun, and a Venusian solar year is just under two Venusian days long.

    Water Loss on Venus:

    • Venus lost its water primarily due to two factors:
        • Evaporation due to Greenhouse Effect: Its dense atmosphere rich in carbon dioxide, creating a strong greenhouse effect and surface temperatures around 450 degrees Celsius, which prevents water from existing in liquid form.
        • Proximity to the Sun: This leads to the disintegration of water molecules into hydrogen and oxygen in the ionosphere under solar heat and ultraviolet radiation.
    • Mechanism of Water Loss:
    1. Thermal Process: Initially, hydrodynamic escape was significant, where solar heating caused the outer atmosphere to expand, allowing hydrogen to escape into space. This process cooled and slowed about 2.5 billion years ago.
    2. Non-Thermal Process: Focus of recent study; involves hydrogen escaping into space, reducing water formation as oxygen atoms lack hydrogen to bond with.

    Key Research Findings: Non-thermal Dissociative Recombination (DR)

    The discrepancy in water loss rates was addressed by identifying a previously overlooked chemical reaction involving the formyl cation (HCO+).

    • HCO+ dissociative recombination (DR) reaction occurs when HCO+ gains an electron and splits into CO and a hydrogen atom, which then escapes into space.
    • This reaction is responsible for losing out water without evaporation.
    • This reaction was modelled to significantly increase the rate of hydrogen escape, potentially doubling the rate at which Venus lost water.
    • The model suggests that water levels on Venus would have been stable from nearly 2 billion years ago due to the ongoing non-thermal HCO+ DR reaction, yet some water remains today.

    Future Research on Venus

    • Existence of HCO+ Ions: Direct evidence of HCO+ ions in Venus’s atmosphere is still missing. Past missions did not focus on this molecule, and its involvement in water loss was not previously considered crucial.
    • Future Missions: The findings underscore the importance of future Venus missions to investigate the presence of HCO+ in the upper atmosphere, similar to the MAVEN mission to Mars.

  • The challenge of Extra-Pulmonary TB

     

    Why in the News? 

    A tuberculosis patient receives treatment from a nurse (instead of a specialist) at a TB hospital in Guwahati.

    What is meant by Pulmonary Tuberculosis (TB)?  

    • Pulmonary tuberculosis (TB) is a serious infection caused by the bacterium Mycobacterium tuberculosis (MTB) that involves the lungs but may spread to other organs where it destroys body tissue. TB is a contagious disease that can infect anyone exposed to MTB.
    • It constitutes a significant portion of the TB burden in India, accounting for more than 20% of cases.

    Present status of Extra-Pulmonary Tuberculosis (EPTB) in India:

    According to the World Health Organization (WHO) reports, there are over 10 million new cases of TB every year and India alone accounts for 27% of the global TB burden. However, the burden of EPTB is hard to estimate. EPTB is often stain-negative, which means it is not detectable on regular TB stain tests.

     

    The twin challenges of the Knowledge Gap: 

    • Lack of awareness:
      • Among Physicians: Many healthcare providers are unaware that TB can affect organs other than the lungs, such as the eyes and other immune-privileged sites.
      • Among Patients: Nearly 1/5th of TB patients have EPTB. Most of them go undiagnosed, and the few who are diagnosed cannot benefit from care unless they visit a few specialist health facilities.
    • Lack of Accurate Diagnostic and Treatment Criteria: There is a lack of accurate diagnostic criteria for EPTB, making it challenging to identify the disease correctly. Treatment protocols for EPTB are not well-established or widely known, complicating effective management.
      • Although guidelines like INDEX-TB (a set of guidelines by WHO for EPTB management in India) have been formulated, their implementation has remained dormant.
      • The current system for collecting EPTB data is fragmented, with specialist departments maintaining diverse data practices.
      • National Patient Management Portals, such as Ni-kshay in India, have incomplete and missing data on EPTB patients.

    Need to Prioritize Research and Development (R&D) for EPTB:

    • Need to understand the infection mechanism deeply: A troubling aspect of EPTB infection is the prolonged presence of disease markers even after the infection is resolved with treatment.
      • This phenomenon causes a lot of misery to persons with EPTB and is an active area of research.
    • Prioritize Advanced Immunological Tools: Advanced Immunological Tools such as single-cell RNA sequencing, will be able to uncover the immune mechanisms for the disease.
      • This will also help physicians to understand the treatment better, instead of going for long-duration anti-TB therapy (sometimes for even two years or more).

    Mains PYQ: 

    Q Can overuse and free availability of antibiotics without a Doctor’s prescription, be contributors to the emergence of drug-resistant diseases in India? What are the available mechanisms for monitoring and control? Critically discuss the various issues involved.

  • AI Content Detectors to Combat Deepfakes

    Why in the News?

    During the General Elections 2024, the proliferation of AI-generated content (AIGC), including deepfake videos featuring prominent figures like Aamir Khan and Ranveer Singh, raised concerns about misinformation.

    What is Deepfake Technology?

    • It is a type of Artificial Intelligence used to create convincing images, audio and video hoaxes. Deepfakes often transform existing source content where one person is swapped for another.
    • Creating such content involves a technique known as Generative Adversarial Networks (GANs), comprising Artificial Neural Networks.

    Legal Safeguards in India:

    • The regulations under the IT Act of 2000 and 2021 requires social media intermediaries to promptly remove deepfake content. Failure to do so may result in imprisonment or fines.
      • Section 66D: It penalizes individuals for cheating through personation using communication devices or computer resources. (Imprisonment for up to 3 yrs and a fine of up to 1 lakh rupees)
      • Rule 3(1)(b)(vii): This rule mandates that social media intermediaries prevent the hosting of content impersonating others.
      • Rule 3(2)(b): This rule requires social media platforms to remove such content within 24 hours of receiving a complaint.

    Significance of Deepfake Technology:

    • Promotes Right to Expression: Deepfakes amplify voices of marginalised individuals, enabling them to share important messages. Recently, a video was created to deliver the final message of a journalist killed by the Saudi government, calling for justice.
    • Can contribute to the Education System: Online educators use deepfakes to bring historical figures to life for engaging lessons. For example, a video of Abraham Lincoln delivering his Gettysburg.
    • Provides Autonomy: Deepfakes empower individuals to control their digital identity and explore new forms of self-expression. For instance, the Reface App.
    • Provides a realistic experience: Artists leverage deepfakes for creative expression and collaboration, as seen in Salvador Dali’s interactive museum promotion. Deepfake tech enables realistic lip-syncing for actors speaking different languages, enhancing global accessibility and immersion in films.
    • Renovating old memories: Deepfakes aid in restoring old photos, enhancing low-quality footage, and creating realistic training materials for public safety.

    What are the limitations of Deepfake Technology?

    • Spreading False Information: Deepfakes can purposefully spread misinformation, influencing public opinion or elections, like the videos of politicians/celebrities can manipulate viewers and create confusion about important issues.
    • Frauds: Deepfake technology enables impersonation for financial frauds, tricking individuals into revealing sensitive information. They can also fuel harassment, especially targeting women, and lead to psychological distress.
    • Accuracy: While no AI detector guarantees 100% accuracy, tools like Originality.ai boast a 99% true positive rate. Detection models report probability scores, allowing for nuanced assessments despite inherent uncertainties.

    Future Scope:

    • Adversarial AI: Keeping pace with evolving generative AI models poses a significant challenge for content detectors.
    • Accessibility and Cost: With increased adoption and advancements, the accessibility and affordability of detection tools are expected to improve.

  • What is 3D Printing and How does it Work?

    Why in the news?

    • The Indian Space Research Organisation (ISRO) successfully tested a liquid rocket engine made with the help of additive manufacturing technology — commonly known as 3D printing.

    3D Printed PS4 Engine

    • The technology helped ISRO bring down the number of parts in the engine from 14 to a single piece.
    • ISRO was able to eliminate 19 weld joints and saved 97% of raw material.
    • It also reduced the overall production time by 60%.

    What is 3D printing?

    • 3D printing is a process that uses computer-created design to make three-dimensional objects layer by layer.
    • It is an additive process, in which layers of a material like plastic, composites or bio-materials are built up to construct objects that range in shape, size, rigidity, and colour.
    • Common 3D Printing materials include Acrylonitrile Butadiene Styrene (ABS), Carbon Fiber Filaments, Conductive Filaments, Metal Filaments etc.

    How is 3D printing done?

    • To carry out 3D printing, one needs a personal computer connected to a 3D printer.
    • All they need to do is design a 3D model of the required object on computer-aid design (CAD) software and press ‘print’.
    • The 3D printer does the rest of the job.
    • 3D printers construct the desired object by using a layering method, which is the complete opposite of the subtractive manufacturing processes.

    Benefits offered:
