Poor fungal infection diagnosis may up antibiotic resistance (hindu)

Paying closer attention to underlying fungal infections is necessary to reduce drug resistance, researchers say.

Poor diagnosis worldwide of fungal disease causes doctors to over-prescribe antibiotics, increasing harmful resistance to antimicrobial drugs, a new study has warned.

According to World Health Organisation (WHO), antibiotic resistance is one of the biggest threats to global health. It is linked to 23,000 deaths per year, researchers said.

Paying closer attention to underlying fungal infections is necessary to reduce drug resistance, they said.

“If we are trying to deliver globally on a comprehensive plan to prevent antimicrobial resistance, and we are treating blindly for fungal infections that we do not know are present with antibiotics, then we may inadvertently be creating greater antibiotic resistance,” said lead author David Perlin, from Rutgers New Jersey Medical School in the U.S.

Inexpensive, rapid diagnostic tests are available for important fungal infections, but are not being widely used, said Mr. Perlin.

Better training is needed to encourage health care practitioners to test for fungal infections so the correct drugs are administered.

The report cites four common clinical situations in which a lack of routine diagnostic testing for fungal diseases often worsens the problem.

It said many people diagnosed with tuberculosis of the lungs do not have TB — known as smear negative cases — but are treated ineffectively with costly TB drugs.

A simple antibody test can pick up the fungus Aspergillus, which can be treated by antifungal drugs rather than unnecessary anti-TB antibiotics. In 2013, more than 2.7 million smear-negative TB cases were reported to the WHO.

Inaccurate diagnosis of fungal sepsis in hospitals and intensive care units results in inappropriate use of broad-spectrum antibacterial drugs in patients with invasive candidiasis, fungal infections caused by yeasts.

Fungal asthma is often misdiagnosed as chronic obstructive pulmonary disease (COPD) and treated with antibacterial drugs and steroids.

Of more than 200 million asthma sufferers, an estimated 6 million to 15 million have fungal asthma, which can be diagnosed with skin testing or blood tests and responds to antifungal agents, not antibiotics, the report notes.

“Fungal disease diagnostics are critical in the AMR fight and will improve survival from fungal disease across the world,” said David Denning from the University of Manchester in the U.K.

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment].

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo...

What's ailing Namami Gange programme?(DTE)

Winters are extremely hectic for Sushma Patel, a vegetable grower in Uttar Pradesh’s Chunar town. Her farm is in the fertile plains of Ganga where people grow three crops a year. But this is the only season when she can grow vegetables. And before that, she needs to manually dig out shreds of plastic and wrappers from her one-hectare (ha) farm. “This is all because of the nullah,” she says, pointing at an open drain that runs through her field, carrying sewage from the neighbourhood to the Ganga. “Every monsoon, the drain overflows and inundates the field with a thick, black sludge and plastic debris. We cannot even go near the field as the stench of sewage fills the air,” she says. But Patel has no one to complain to as this is the way of life for most people in this ancient town. About 70 per cent of the people in Chunar depend on toilets that have on-site sanitation, such as septic tanks and pits. In the absence of a proper disposal or management system, people simply dump the faec...
