Fungal infections in the brain aren’t just the stuff of movies — Africa grapples with a deadly epidemic

Fungi are present everywhere in our environment: in the air, in the soil, in decaying plant material, on our skin, and even in the gut as part of our natural flora.

Microscopic, disease-causing fungi can invade various parts of the body, leading to a range of symptoms and health problems. In fact, fungal infections contribute to about 1.5 million deaths every year.

Fungal infections

  • For the greater part of the history of humankind, fungal infections were never a threat to human health. This is mainly because most fungi cannot survive the warm human body temperature of 37°C. However, climate change and other environmental pressures have led to the emergence of species of fungi that are capable of surviving at human body temperatures.
  • Even then, our immune systems are quite capable of fighting against fungal infections. For instance, our bodies can create localized acidic environments, limit micronutrient availability and release antimicrobial agents.
  • However, when the immune system is weakened, fungi are able to evade the body’s defences and avoid detection. They can generate bioactive agents which help them evade or adjust to the host immune response. Some adapt to survive in hostile, low-nutrient and low-oxygen environments.

Some examples

  • One example of opportunistic fungal diseases is cryptococcal meningitis, which emerged with the HIV pandemic in the late 1980s. Today, sub-Saharan Africa contributes about 73% of all global cases and deaths resulting from the disease. Cryptococcal meningitis is caused by the fungus Cryptococcus neoformans, which is found in soil and bird droppings.
  • The development of cheaper drugs has been hindered by a limited understanding of how the fungus causes such extreme damage in the brain.
  • Another example of an HIV-related opportunistic fungal disease is pneumocystis jirovecii pneumonia. It’s caused by a ubiquitous, airborne fungus Pneumocystis jirovecii, which is passed on from person to person. Pneumocystis hardly causes trouble in people with healthy immune systems, but they act as reservoirs and pass the infection to those with poor immune systems, who may develop serious symptoms including fever, a dry cough and trouble with breathing. Pneumocystis jirovecii pneumonia occurs in 15%-20% of HIV patients who present with respiratory problems.
  • The diagnosis of pneumocystis jiroveci pneumonia is expensive and requires a well-equipped laboratory. In Africa’s poor urban and rural healthcare facilities this will be a challenge. The fungus, P. jirovecii, is also extremely difficult to culture, which limits diagnosis and research.

Growing burden

The COVID pandemic seems to have made the global fungal burden worse. For instance, recent studies have shown that people who were infected with COVID and have recovered are vulnerable to infection with a fungus called mucormycosis, also known as the black fungus. COVID-induced lung damage, high blood sugar, and the steroids often used to treat it are all predisposing factors to black fungus infection. With a reduced capacity to clear fungal spores and a reduced immune response, thanks to the steroids, the fungus can gain entry and infect the sinuses and facial bones, eventually moving to the brain.

Antifungal drugs

  • Most of the population affected by fungal infections live in rural or poor urban settlements.
  • With poorly funded and overburdened healthcare systems, many African countries are not well prepared to deal with fungal infections. Additionally, some of the WHO-recommended antifungal drugs – such as flucytosine – are unavailable in most African countries. Ineffective and even rather toxic drugs are sometimes used instead.
  • The emergence of drug-resistant fungal strains is also a growing threat. Of great concern is the rise in multi-drug resistant Candida species, azole-resistant Aspergillus species and clinically resistant Cryptococcus.

Hepatitis

  • Hepatitis is inflammation of the liver.
  • Inflammation is swelling that happens when tissues of the body are injured or infected.
  • It can damage your liver. This swelling and damage can affect how well your liver functions.
  • Hepatitis can be an acute (short-term) infection or a chronic (long-term) infection.
  • What causes hepatitis? There are different types of hepatitis, with different causes:
    • Viral hepatitis is the most common type. It is caused by one of several viruses -- hepatitis viruses A, B, C, D, and E.
    • Alcoholic hepatitis is caused by heavy alcohol use.
    • Toxic hepatitis can be caused by certain poisons, chemicals, medicines, or supplements.
    • Autoimmune hepatitis is a chronic type in which your body''s immune system attacks your liver. The cause is not known, but genetics and your environment may play a role.
  • How is viral hepatitis spread?
    • Hepatitis A and hepatitis E usually spread through contact with food or water that is contaminated with an infected person''s You can also get hepatitis E by eating undercooked food.
    • Hepatitis B, hepatitis C, and hepatitis D spread through contact with the blood of someone who has the disease.
    • Hepatitis B and D may also spread through contact with other body fluids. This can happen in many ways, such as sharing drug needles or having unprotected sex.
  • Symptoms: Some people with hepatitis do not have symptoms and do not know they are infected. Common symptoms include:
  • Fever
    • Fatigue
    • Loss of appetite
    • Nausea and/or vomiting
    • Abdominal pain
    • Dark urine
    • Clay-coloured bowel movements
    • Joint pain
    • Jaundice, yellowing of your skin and eyes
  • Treatment:
    • Treatment for hepatitis depends on which type you have and whether it is acute or chronic.
    • Acute viral hepatitis often goes away on its own.
    • There are different medicines to treat the different chronic types of hepatitis.
    • Possible other treatments may include surgery and other medical procedures.

Andhra Pradesh: Carcass of blue whale washes ashore at Meghavaram beach in Srikakulam district

Blue whale

  • Blue whales are the largest animals ever to live on our planet.
  • Whales are at the top of the food chain and have an important role in the overall health of the marine environment.
  • Habitat: They are found in all oceans except the Arctic Ocean.
  • They generally migrate seasonally between summer feeding grounds and winter breeding grounds
  • Lifespan: The average lifespan is estimated at around 80 to 90 years. Scientists can estimate the age of whales by counting the layers of wax-like earplugs collected from deceased animals.
  • Behaviour and Diet
    • They sometimes swim in small groups but are more often found alone or in pairs.
    • They generally spend summers feeding in polar waters and undertake lengthy migrations towards the equatorial waters as winter arrives.
    • The primary diet whale is krill—tiny shrimp-like animals, but fish and copepods (tiny crustaceans) may occasionally be part of the blue whale’s diet.
  • IUCN: Endangered

Ladakh glacier melting may form three lakes, says study

  • The Parkachik glacier is one of the largest glaciers in the Suru River valley, covering an area of 53 square km and is 14 km long.
  • The Suru River valley is a part of the southern Zanskar Ranges in the western Himalayas.
  • There are two main reasons for the rapid melting of the glacier.
    • The first is global warming and increasing temperatures in the region.
    • The second is that it is at a lower altitude than other glaciers in the Zanskar region.

Zanskar Ranges

  • Zanskar is a high altitude semi-desert lying on the Northern flank of the Great Himalayan Range.
  • This mountain range acts as a climatic barrier protecting Ladakh and Zanskar from most of the monsoon, resulting in a pleasantly warm and dry climate in the summer.
  • Flora: Much of Zanskar''s vegetation is found in the lower reaches of the valleys, and consists of alpine and tundra species.
  • Fauna: Among the wildlife that can be found in Zanskar are the marmot, bear, wolf, snow leopard, kiang, bharal, alpine Ibex, wild sheep and goats, and the lammergeier.

Carbon monoxide-resistant copper-cobalt nanocrystal@ nitrogen-doped carbon electrocatalysts for methanol oxidation reaction

  • Researchers have synthesized a trimetallic PtMnCo catalyst that displayed superior catalytic activity and high CO tolerance when compared to commercially available catalyst.
  • The choice of Manganese (Mn) as a dopant was based on its abundance and affordability and the multiple oxidation states it offers making it a good candidate for electro-catalysis.
  • Significance of DMFC
    • Among the different classes of fuel cells proposed, DMFCs have long been considered an attractive alternate power source for small vehicles such as forklifts and as battery chargers for mobile phones, digital cameras, laptops, and other small electronic gadgets.
    • It has high energy densityhigh efficiency, and low operating temperature.
    • They are also much safer to operate because they deal with liquid fuel (methanol).
  • The **methanol oxidation reaction (**MOR) at the anode and oxygen reduction reaction (ORR) at the cathode are the main processes that determine the performance of DMFCs.
  • Platinum is the most often used MOR catalyst. However, fundamental challenges such as slow kinetics, high manufacturing costs (due mostly to the pricey Pt-based catalyst), and CO poisoning of the Pt catalyst make commercialization of DMFCs challenging.
  • Therefore, the search for an alternative Pt-based catalyst that circumvents the above issues is one of the most pressing research problems with respect to DMFCs.
  • Alloying Pt with other transition metals such as (Ru, Co, Ni, and Fe) is thought to be a useful strategy for improving the catalytic performance and durability of Pt catalyst along with reducing the amount of Pt being used in the catalyst.

Graded Response Action Plan:

  • It is a set of emergency measures that kick in to prevent further deterioration of air quality once it reaches a certain threshold in the Delhi-NCR region.
  • The GRAP was first notified in January 2017 by the Ministry of Environment, Forest and Climate Change.
  • Implementation:
    • The Commission for Air Quality Management (CAQM) has constituted a sub-committee for the operationalization of the GRAP.
    • This body includes officials from the CAQM, member secretaries of pollution control boards of Uttar Pradesh, Delhi, Haryana, Rajasthan, the Central Pollution Control Board, a scientist from the IMD and one from the IITM and Health Advisor.
    • The sub-committee is required to meet frequently to issue orders to invoke the GRAP.
    • The orders and directions of the CAQM will prevail in case of any conflict between directions issued by the State governments and the CAQM.

Revised measures

  • Stage I – ‘Poor’ Air Quality (AQI ranging between 201-300): Enforce NGT / Hon’ble SC’s order on over aged diesel / petrol vehicles.
  • Stage II - ''Very Poor'' (AQI 301-400): Rigorous actions to combat air pollution at identified hotspots in the region.
  • Stage III - ''Severe'' (AQI 401-450): Impose strict restrictions on BS III petrol and BS IV diesel four-wheelers in certain areas and may suspend physical classes in schools for primary grade children up to Class 5.
  • Stage IV - ''Severe Plus'' (AQI greater than 450) : When the AQI exceeds 450, four-wheelers registered outside Delhi, except for electric vehicles, CNG vehicles, and BS-VI diesel vehicles, will not be allowed to enter the city.
