  • Solar and Heliospheric Observatory (SOHO) discovers 5000th Comet

    Why in the news?

    A Czech citizen has spotted a comet in an image from the Solar and Heliospheric Observatory (SOHO) spacecraft, which has now been confirmed to be the 5,000th comet discovered using SOHO data.

    Solar and Heliospheric Observatory (SOHO)

    • The SOHO is a spacecraft jointly operated by the European Space Agency (ESA) and NASA.
    • Launched in December 1995, its primary mission is to study the Sun, particularly its outer atmosphere, known as the corona, and the solar wind.
    • SOHO observes the Sun in various wavelengths of light, enabling scientists to study phenomena such as sunspots, solar flares, and coronal mass ejections.
    • SOHO orbits the Sun at Lagrange Point L1, about 1.5 million kilometers (nearly 1 million miles) from Earth, providing an uninterrupted view of the Sun.
    • Its observations have led to discoveries such as-
    1. Identifying the source regions of solar wind,
    2. Tracking solar eruptions, and
    3. Monitoring changes in the Sun’s activity over its 11-year solar cycle.

     

    What are Lagrange Points?

    • Lagrange Points are named after the French mathematician Joseph-Louis Lagrange who discovered them in 1772.
    • They are specific points in space where the gravitational forces of two large bodies, such as the Earth and the Sun, or the Earth and the Moon, balance the centrifugal force felt by a smaller body.
    • These points are stable locations where objects can maintain their relative positions concerning the larger bodies, without drifting away or falling towards them.

    There are five Lagrange Points, denoted as L1, L2, L3, L4, and L5:

    1. L1: Located on the line connecting the two large bodies and closer to the smaller body, L1 is particularly useful for space observatories like the Solar and Heliospheric Observatory (SOHO) because it provides an unobstructed view of the Sun from Earth’s perspective.
    2. L2: Situated on the opposite side of the smaller body from the larger one, L2 is an excellent location for deep space observatories such as the James Webb Space Telescope (JWST) because it remains relatively shielded from solar interference.
    3. L3: Located on the line connecting the two large bodies but on the opposite side of the larger body from the smaller one, L3 is less stable and less frequently used than the other Lagrange Points.
    4. L4 and L5: These points form equilateral triangles with the two large bodies, with the smaller body at the third vertex. L4 precedes the smaller body in its orbit, while L5 follows it. These points are stable and have been found to accumulate natural objects, such as asteroids, known as Trojan asteroids.

  • 50,000-year-old Magnetic Fossils found in Bay of Bengal

    What is the news?

    Scientists from the CSIR-National Institute of Oceanography, Goa have found in the Bay of Bengal a 50,000-year-old sediment containing giant magnetofossils, shedding light on ancient geological conditions.

    What are Magnetofossils?

    • Magnetofossils are fossilized magnetic particles created by magnetotactic bacteria, aiding scientists in understanding past environmental conditions.
    • Described initially in the 1960s and 1970s, magnetotactic bacteria utilize iron-rich minerals to navigate the Earth’s magnetic field, leaving behind distinctive fossil remnants.
    • These unique creatures were first described in 1963, by Salvatore Bellini, an Italian doctor and then again in 1975 by Richard Blakemore of the Woods Hole Oceanographic Institution, Woods Hole, Massachusetts.
    • These organisms were believed to follow the magnetic field to reach places that had optimal oxygen concentration.
    • Using an electron microscope, Blakemore found the bacteria contained “novel structured particles, rich in iron” in small sacs that essentially worked as a compass.
    • These magnetotactic bacteria create tiny crystals made of the iron-rich minerals magnetite or greigite, aiding them in navigating changing oxygen levels in the water body they reside in.

    Special Attributes of Bay of Bengal Sediment

    • Previous studies on magnetofossils often ascertained their origins to be hyperthermal vents, comet impacts, changes in oceanic ventilation, weathering or the presence of oxygen-poor regions.
    • Sediments deposited at the core site originate from the Godavari, Krishna, and Penner Rivers, highlighted on the map.

    Findings of the Study

    • Scientific Approach: In the study, combined magnetic analyses and electron microscopy to study the sediment sample.
    • Sediment Characteristics: The three-metre-long sediment core from the southwestern Bay of Bengal consisted mainly of “pale green silty clays,” they wrote in their paper. They also reported finding abundant benthic and planktic foraminifera — single-celled organisms with shells found near the sea bed and free-floating in water.
    • Microscopic Revelations: High-resolution transmission electron microscopy revealed the fossil to be in the shape of needles, spindles, bullets, and spearheads.
    • Environmental Insights: Earlier, studies of sediments suggested that nearly 29,000 to 11,700 years ago, during the last Glacial Maximum-Holocene period, the northeast and southwest monsoon strengthened and resulted in significant weathering and sedimentation.

     

    PYQ:

  • On the resurgence of Mumps in Kerala

    Why in the news? 

    Mumps, an acute viral infection that historically affects children, has been spreading like wildfire in Kerala, for the past few months.

    Context:

    • Despite being a vaccine-preventable disease, mumps has never been a part of the Universal Immunisation Programme (UIP) because of the disease’s no-mortality profile and the perception that it has low public health significance.
    • According to the World Health Organization (WHO), vaccination strategies targeting mumps control should be closely integrated with existing measles elimination and rubella control.

    About: Mumps is an airborne viral disease primarily affecting children and adolescents. It manifests with symptoms like fever, headache, and painful swelling of the salivary glands, particularly the parotid glands on both sides of the face.

    Is it a cause for concern? 

    • Self-Limiting Disease: Mumps is described as a self-limiting disease, meaning it typically resolves on its own with rest and symptomatic management within about two weeks.
    • Underreporting: Due to approximately half of infected children developing classical symptoms and around 30% remaining asymptomatic, many cases of mumps go unreported. This suggests that reported cases are likely a significant underestimation of the actual prevalence in the community.
    • Public Health Perspective: Historically, measles has been prioritized in public health efforts due to its potential for severe morbidity and mortality, overshadowing the attention given to mumps.
    • Emerging Concerns: Despite being less prioritized, recent reports indicate a surge in mumps cases, including complications such as encephalitis, epilepsy, aseptic meningitis, and acute pancreatitis, particularly at Kozhikode Medical College hospital.
    • Impact on Reproductive Health: Mumps can affect the gonads (reproductive glands) in both males and females. In males, it poses the rare but significant risk of infertility or reduced sperm count in the long term.

    Why is the mumps vaccine not part of the national immunization schedule?

    • Lack of Mortality: Mumps typically does not result in fatalities, further contributing to the belief that it may not warrant inclusion in routine vaccination schedules.
    • Underestimation of Public Health Significance: Despite arguments from organizations like the Indian Academy of Pediatrics (IAP) that mumps’ public health significance is underestimated, there has been insufficient evidence or data to prompt its inclusion in national immunization programs.
    • Poor Documentation and Lack of Studies: Limited documentation of clinical cases, complications, and follow-up data, as well as a scarcity of published studies on mumps, have hindered efforts to fully understand its impact and advocate for its vaccine inclusion.
    • Absence of Nationally Representative Data: The lack of nationally representative data on the incidence of mumps in India makes it challenging to assess its burden accurately and advocate for vaccine inclusion based on epidemiological evidence.
    • Limited Information on Long-Term Morbidity: While mumps is known to have some impact on reproductive organs, there is very little information available on its actual long-term morbidity profile, further complicating decisions regarding vaccine inclusion.

    How can the current outbreaks be controlled?

    • Public Awareness Campaigns: Launch comprehensive public awareness campaigns to educate the community about mumps, its symptoms, transmission, and the importance of isolation. Emphasize the significance of vaccination and maintaining good hygiene practices.
    • Improve Immunization Coverage: Strengthen efforts to improve general immunization coverage, especially targeting unimmunized children and adolescents. Ensure accessibility to vaccination services in all communities.
    • Strict Isolation Measures: Enforce strict isolation measures for mumps patients for the full three-week duration to limit disease transmission. Provide clear guidelines to healthcare facilities and schools on managing mumps cases and preventing spread.
    • School Closure: Consider temporary closure of schools during outbreaks to prevent further transmission, especially if a significant number of cases are reported among students. Use the summer break as an opportunity to break the chain of transmission.
    • Enhanced Surveillance and Reporting: Implement robust surveillance systems to promptly detect and report mumps cases. Ensure healthcare providers are vigilant in diagnosing and reporting suspected cases to public health authorities for timely intervention.
    • Contact Tracing and Monitoring: Conduct thorough contact tracing of individuals who have been in close contact with confirmed mumps cases. Monitor them for symptoms and enforce isolation measures if necessary to prevent secondary transmission.
    • Healthcare Provider Training: Provide training to healthcare providers on mumps diagnosis, management, and reporting protocols. Ensure they are equipped to identify and manage cases effectively.
    • Community Engagement: Engage with community leaders, schools, and parents to encourage cooperation with control measures. Encourage individuals to seek medical care promptly if they develop symptoms suggestive of mumps.

    Way Forward:

    • Assessment of Vaccine Effectiveness: Despite the lack of studies on the effectiveness of the mumps vaccine in India, global data suggests that two doses of the MMR vaccine can provide protection ranging from 70% to 95%, provided that coverage is high.
    • Integration with Measles and Rubella Control: The World Health Organization (WHO) recommends integrating mumps vaccination strategies with existing efforts for measles elimination and rubella control. This ensures a comprehensive approach to vaccine-preventable diseases.
    • Consideration of Regional Factors: Evaluate regional factors influencing vaccine effectiveness, disease burden, and immunization coverage. Tailor vaccination strategies accordingly to address the specific needs and challenges faced in Kerala.
    • Consultation with Experts and Stakeholders: Engage with public health experts, immunization specialists, and stakeholders to review the evidence, assess the impact of different vaccination strategies, and determine the most effective approach moving forward.
    • Monitoring and Surveillance: Strengthen monitoring and surveillance systems to track mumps cases, vaccine coverage, and vaccine effectiveness. This data will be crucial for evaluating the impact of vaccination strategies and making informed decisions.
    • Policy Decision: Based on the evidence and expert recommendations, make a policy decision regarding the inclusion of MMR vaccine in the Universal Immunization Programme. Consider factors such as vaccine availability, cost-effectiveness, and logistics.

    Conclusion: Addressing the resurgence of mumps in Kerala necessitates a comprehensive approach, including vaccination integration, public awareness, strict isolation measures, and policy review guided by expert consultation and regional considerations.

  • Clinical Trials for MTBVAC Tuberculosis Vaccine in India

    What is the news?

    • Bharat Biotech, in collaboration with Spanish biopharmaceutical company Biofabri, has initiated clinical trials for the Mycobacterium Tuberculosis Vaccine (MTBVAC) in India, marking a significant milestone in TB vaccine development.
    • The only currently available TB vaccine, the Bacillus Calmette-Guérin vaccine (BCG), was developed 100 years ago and is less effective.

    About MTBVAC

    • MTBVAC is a unique TB vaccine based on a genetically modified form of Mycobacterium tuberculosis, containing all antigens present in human-infecting strains, unlike the BCG vaccine.
    • It is developed in the laboratory of the University of Zaragoza with contributions from Dr. Brigitte Gicquel of the Pasteur Institute, Paris.
    • MTBVAC is designed to offer superior and potentially longer-lasting protection compared to the BCG vaccine, particularly for newborns and in preventing TB in adults and adolescents.

    Objectives of Clinical Trials in India

    • Safety and Immunogenicity: The ongoing trials in India aim to evaluate the safety and immunogenicity of MTBVAC, with plans for a pivotal Phase 3 trial in 2025.
    • Population Significance: Studying the vaccine’s efficacy in India, with its high TB burden, is crucial for advancing TB vaccine research and addressing the global TB epidemic.

    What is Tuberculosis?

    • Tuberculosis is an infection caused by Mycobacterium tuberculosis.
    • Robert Koch discovered Mycobacterium tuberculosis which causes TB, and his discovery opened the way towards diagnosing and curing this disease.
    • It can practically affect any organ of the body.
    • The most common ones are lungs, pleura (lining around the lungs), lymph nodes, intestines, spine, and brain.

    Transmission:

    It is an airborne infection that spreads through close contact with the infected, especially in densely populated spaces with poor ventilation.

    Symptoms:

    Common symptoms of active lung TB are cough with sputum and blood at times, chest pains, weakness, weight loss, fever and night sweats.

    Treatment Facilities in India:

    • DOTS (Directly Observed Treatment, Short-Course) regimen: It is the recommended treatment approach for TB by the WHO. Patients receive a combination of four antibiotics: isoniazid, rifampicin, pyrazinamide, and ethambutol. These drugs are usually administered daily for the first two months of treatment, followed by a continuation phase with isoniazid and rifampicin for an additional four to seven months.
    • Nikshay Poshan Yojana (2018): It was launched to support every Tuberculosis (TB) Patient by providing a Direct Benefit Transfer (DBT) of Rs 500 per month for nutritional needs.

    Issues in TB Treatment: Drug Resistance

    Drug resistance emerges when anti-TB medicines are used inappropriately, through incorrect prescription by health care providers, poor quality drugs, and patients stopping treatment prematurely.

    1. Multidrug-resistant tuberculosis (MDR-TB): Itis a form of TB caused by bacteria that do not respond to isoniazid and rifampicin, the 2 most powerful, first-line anti-TB drugs. MDR-TB is treatable and curable by using second-line drugs such as
    2. Extensively drug-resistant TB (XDR-TB): Itis a more serious form of MDR-TB caused by bacteria that do not respond to the most effective second-line anti-TB drugs, often leaving patients without any further treatment options.

     

    PYQ:

    2014: Can overuse and free availability of antibiotics without 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.

    • Project ANAGRANINF is titled “Development of a Novel Class of Antibiotics Against Gram-Negative Bacterial-Infections.”
    • It is a collaborative initiative involving M/s Peptris Technologies Pvt. Ltd. and the Foundation for Neglected Disease Research (FNDR) in India, along with ABAC THERAPEUTICS SL from Spain.
    • The primary objective of the project is-
    1. To develop a novel antibiotic capable of inhibiting the FabI enzyme and
    2. Combating critical gram-negative pathogens.
    • Project ANAGRANINF aims to produce a series of compounds with enhanced efficacy against gram-negative bacterial infections.
    • The project aims to identify a candidate molecule that meets WHO’s innovation criteria, ensuring a new chemical structure, no cross-resistance with existing antibiotic classes, and a novel mechanism of action.

    About the Candidate Molecule ‘MMV1578564’

    The selected hit molecule from the project, MMV1578564, has exhibited promising activity against gram-negative pathogens, providing a foundation for further research and development efforts.

    Back2Basics:

    1. Gram-Negative Bacteria:
      • Gram-negative bacteria have a thin peptidoglycan layer in their cell wall, which is located between the outer and inner membranes.
      • They stain pink or red when subjected to the Gram staining technique.
      • Gram-negative bacteria are generally more resistant to antibiotics due to the presence of an outer membrane that acts as a barrier against certain antibiotics.
      • Examples of gram-negative bacteria include Escherichia coli (E. coli), Salmonella spp., Pseudomonas aeruginosa, and Neisseria gonorrhoeae.
      • They are known to cause infections like pneumonia, bloodstream infections, wound infections, and meningitis in healthcare settings
    2. Gram-Positive Bacteria:
      • Gram-positive bacteria have a thick layer of peptidoglycan in their cell wall, which retains the crystal violet stain used in the Gram staining technique.
      • They appear purple or blue under a microscope after staining.
      • Gram-positive bacteria are generally more susceptible to antibiotics because their thick peptidoglycan layer allows antibiotics to penetrate more easily.
      • Examples of gram-positive bacteria include Staphylococcus aureus, Streptococcus pneumoniae, Bacillus subtilis, and Clostridium difficile.
      • Some examples of diseases caused by Gram-positive bacteria include anthrax, diphtheria, enterococcal infections, erysipelothricosis, and listeriosis.These bacteria can cause a range of infections from food poisoning to serious respiratory diseases and may require specific antibiotics for treatment.
