U.S. approves pill camera

A kinder, gentler approach to one of the most dreaded exams in medicine is on the way — U.S. regulators have cleared a bite-size camera to help screen the large intestine of patients who have
trouble with colonoscopies.
The ingestible pill camera from Given Imaging is designed to help doctors spot polyps and other early signs of colon cancer. The Food and Drug Administration cleared the device for patients who have had trouble with the cringe-inducing procedure, which involves probing the colon using a tiny camera on a four-foot long, flexible tube.
The pill camera was previously approved in 80 other countries, including in Japan, Europe and Latin America.
The Israeli company’s technology, developed from missile defence systems, uses a battery-powered camera to take high-speed photos as it slowly winds its way through the intestinal tract over eight hours. The images are transmitted to a recording device worn around the patient’s waist and later reviewed by a doctor.
While Given’s wireless, image-beaming system may sound like science fiction, it’s actually more than a decade old. In 2001, the company received FDA approval for a similar device used to get a close-up view of the small intestine.
At that time, analysts expected Given’s approach to grow into a direct competitor with traditional colonoscopy. But company studies found that the images taken by the mini-camera were not quite as clear as those from the in-office procedure. As a result, the company has pursued a more limited market for its PillCam — patients who have trouble undergoing standard colonoscopies.
The Food and Drug Administration approved the company’s PillCam Colon for patients who have experienced an incomplete colonoscopy. The company estimates 750,000 U.S. patients are not able to complete the procedure each year, due to anatomy issues, previous surgery or various colon diseases.
The Centers for Disease Control and Prevention’s guidelines currently recommend regular colonoscopies beginning at age 50 and continuing until age 75, though the majority of American adults don’t follow the recommendations. — AP

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]. Having

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

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i
