New Delhi: Delhi Health Minister Satyendra Jain today urged Lt. Governor Najeeb Jung and Delhi Police to ensure the safety of doctors in hospitals in the capital.

The appeal from Delhi Health Minister Satyendra Jain follows two incidents of violence against doctors in two hospitals here.

The Minister also asked Police Commissioner B.S. Bassi to probe both the cases and submit a report in 15 days. The two incidents were reported from the Bhagwan Mahavir Hospital and Babu Jagjiwan Ram Hospital.

Jain said: “You are requested to conduct an enquiry in both the incidents and fix responsibility against the guilty. The report … may be sent to me within 15 days.”

In his letter to Jung, Jain wrote: “While you instructed the police to provide adequate security in hospitals, two incidents have taken place…

“In these incidents, policemen were present at the site of the incidents. (But) they did not prevent the occurrence of the incidents and remained spectators.

“It seems there is a deliberate and malafide action on the part of the police to create such incidents and spread disaffection among the doctors to paralyze the services in the hospitals,” Jain wrote.

He said the police should nominate a senior officer to monitor all such cases.

Resident doctors of 22 government hospitals in Delhi went on strike on June 22-23 seeking security and better healthcare facilities.

From Radio Signals A Pill Could Tell About Gut Health And Help Doctors

Scientists developed a swallowable capsule to detect bleeding in the digestive tract.

A pill could soon radio signals from inside your gut to help doctors diagnose diseases from ulcers to cancer to inflammation, according to a new study.

Scientists have developed a small, swallowable capsule that mixes synthetic biology and electronics to detect bleeding in the digestive tract.

The system can be adapted for a wide range of medical, environmental and other uses, the researchers say.

The biological part of the pill uses bacteria engineered to glow when exposed to heme, the iron-containing molecule in blood.

The electronic side includes a tiny light detector, computer, chip, battery, and a transmitter that sends data to a cell phone or computer.

“A major challenge for sensing in the GI tract is, the space available for a device is very limited,” said Massachusetts Institute of Technology electrical engineer Phillip Nadeau.

Using very low-power electronics they designed, Nadeau and colleagues fit all the components into a capsule about 3 centimeters long by 1 centimeter wide.

It’s still a bit big to swallow. But Nadeau says with engineering work it can likely be made about a third that size.

The engineered bacteria are contained in chambers covered by a membrane that lets small molecules in but does not let the organisms out. The researchers say the bacteria can be engineered to die if they accidentally leak from the capsule. Or future models may just use the key enzymes, rather than whole bacteria.

In laboratory tests, the pill successfully distinguished pigs fed small amounts of blood from those not given blood. The capsule has not yet been tested on humans. The team aims to do so in the next year or two.

Since the components are all fairly cheap to manufacture, the researchers speculate that the cost would be in the range of tens to hundreds of dollars.

And they say the same platform could be used to detect markers of a range of illnesses. Or, it could be used to sense chemicals in the environment.

“It’s really exciting, and I think it’s got a lot of legs,” said Rice University bioengineer Jeff Tabor, who was not part of the research team.

But Tabor notes that the sensors may need to be much more sensitive than what was used in the pig tests. He says there may be much less blood in the guts of actual patients than what the pigs were given. Other conditions may have the same limitations.

“For many actual diseases, you might have far less of the molecule that you need to sense available to you,” he added. (VOA)
