Medical Monopoly for Sickness-care?

I wonder what would happen if there were a legal monopoly on only one system of medicine to take care of the sick people? While formulating the American Constitution, one of the members had strongly argued against letting any one system taking over the medical-care in that country. Though it was accepted, the clause was not included in the preamble. I do not think the Indian Constitution has such a clause in its preamble. Freedom to choose what one wants when one is not well should be the patient’s choice. One should not forget that it is the faith in the doctor, and the system, that cures the patient much more than the drugs given or surgery done, although the latter are also important.
 

Psychiatry under the Influence 

Institutional Corruption, Social Injury, and Prescriptions for Reform is a book by Robert Whitaker and Lisa Cosgrove. It is an investigation into the corrupting influence of pharmaceutical money and guild interests on the behaviour of the APA (American Psychological Association) and academic psychiatry, for the past 35 years, and the resulting social injury. This is a book worth reading by the common man also, as it contains some home truths about what we doctors do.

 

Diabetics and Smelling Problems?

In the studies on rats, scientists have seen specific nerve changes inside the nose that might make their smell capacity get impaired. Did we not know why some Type-II diabetics have smell impairment? Let us not jump to conclusions and try and give treatment for this as rat studies are seriously questioned especially with regard to extrapolating them to humans. 
 

Choice of Hospital for Surgery

A major study showed that surgical mortality was very much related to good nursing care. Although the surgeon might be good, the outcomes eventually depend on good nursing care. So it becomes necessary to look for a hospital where nursing care is of the highest quality. Choosing the hospital might turn out to be as important as selecting the surgeon to operate on you—if it is elective surgery. Of course, in an emergency, one has no chance to do that.
 

Zika Virus Threat

World Health Organization is getting a new team of experts to study the Zika virus threat in detail. However, this is what some known experts like Dr Anne Schuchat have already said: “We don’t yet know what other outcomes might be associated with Zika infection during pregnancy, and there may be other factors in addition to Zika infection that might have increased risk to the foetus.” Further, she said: “More lab testing and other studies are in progress to learn more about the [...] risks of Zika virus infections during pregnancy.” She stressed that it is important for people to remember that the situation is changing rapidly and, as new information concerning the virus comes to light, health organisations may need to update their advice. At this stage, in a relatively new health threat, information evolves quickly. Zika virus is a mosquito-borne mild infection and does not produce any serious disease or death. The big fuss is about its effect on pregnant mothers’ foetus about which there is much speculation.

Indian-origin engineer discovers ground breaking 2D semi-conducting material
New York : A team led by an Indian-origin engineer from the University of Utah has discovered a new kind of 2D semi-conducting material for electronics that opens the door for much speedier computers and smartphones that consume a lot less power.
 
The semi-conductor, made of the elements tin and oxygen or tin monoxide (SnO) by the associate professor Ashutosh Tiwari-led team is a layer of 2D material only one atom thick, allowing electrical charges to move through it much faster than conventional 3D materials such as silicon. 
 
This material could be used in transistors, the lifeblood of all electronic devices such as computer processors and graphics processors in desktop computers and mobile devices. 
 
Transistors and other components used in electronic devices are currently made of 3D materials such as silicon and consist of multiple layers on a glass substrate. 
 
But the downside to 3D materials is that electrons bounce around inside the layers in all directions.
 
“The benefit of 2D materials is that the material is made of one layer the thickness of just one or two atoms. Consequently, the electrons can only move in one layer so it's much faster,” Tiwari said.
 
Transistors made with Tiwari's semi-conducting material could lead to computers and smartphones that are over 100 times faster than regular devices. 
 
“Because the electrons move through one layer instead of bouncing around in a 3D material, there will be less friction, meaning the processors will not get as hot as normal computer chips,” the authors noted. 
 
They will also require much less power to run, a boon for mobile electronics that have to run on battery power. 
 
According to Tiwari, this could be especially important for medical devices such as electronic implants that will run longer on a single battery charge.
 
Now that Tiwari and his team have discovered this new 2D material, it can lead to the manufacturing of transistors that are even smaller and faster than those in use today. 
 
A computer processor is comprised of billions of transistors, and the more transistors packed into a single chip, the more powerful the processor can become.
 
“The field is very hot right now and people are very interested in it," Tiwari said, adding that in two or three years, we should see at least some prototype device.
 
The paper describing the material was published in the journal Advanced Electronic Materials.

Australian mining company finds 404-carat diamond
Perth : A West Australian mining firm has found a record breaking 404-carat diamond believed worth over $14 million.
 
According to reports on Tuesday, the Lucapa Diamond Company, based in Perth but operating in the African nation of Angola, found the 404-carat diamond at its Lulo Diamond Project site, with estimates putting it as the 27th largest diamond ever found, Xinhua news agency reported.
 
The company's chairman, Miles Kennedy, said that the diamond ticked off a "number of firsts" for diamond exploration.
 
"When we first looked at the property, 3,000 sq.km of untouched ground, 700 km inland from the coast, you are talking about a very, very remote area," Kennedy said.
 
"It's the biggest diamond ever recorded from the country of Angola and it's the biggest diamond ever recovered by an Australian diamond miner," he said.
 
The chairman said selling that diamond alone would allow the company to expand its Angola operations.
 
The largest ever 3,167-carat diamond "Sergio" was found in Brazil in 1893.
