Does the FDA approval of aducanumab mark the return of science-based medicine?
The 20th century was an explosion of scientific innovation and discovery. The success of chemistry, physics and biology to produce things such as antibiotics, radiography and genetic analysis could not be ignored. Medicine is not now, nor has it ever been, a“science.” But over the past century, medicine became science-based. This means that whileRead more …Find jobs at Careers by KevinMD.com.

Will It Be A Luxury To Meet Physicians?
In 2013, the World Health Organisation (WHO) rang a bell forecasting a shortfall of 12.9 million healthcare workers globally by 2035. The pandemic has only made things worse. With over half of the world’s population lacking access to essential healthcare, and the increasing leaving of frontline workers after COVID-19, it is easy to sum up: we’re heading towards a healthcare crisis.
Sombre numbers from the 2020 report of the Association of American Medical Colleges (AAMC) project the total physician shortage in the U.S. between 54,100 and 139,000 by 2033. As for Europe, the numbers are similar. According to a WHO...

Physics?
Before I get to today ' s post, an administrative note. The reason Mojrim gets his comments published, even though we don ' t always agree, is that he is not a moron. To get your comments published, you don ' t have to agree with me, you need to have something intelligent and interesting to say. -- C.I have actually never taken a single physics course, in high school or college, which I believe does not make me exceptional. But I ' ve had a subscription to Scientific American since I was 13 and I ' m curious, so I try to understand that stuff as best I can. Modern physics is completely mathematical, however, so qualitative...

Highly Maneuverable Magnetically Controlled Miniature Robots
Researchers at Nanyang Technological University, Singapore have developed miniature robots that are highly maneuverable, and can rapidly move in six degrees of freedom. These tiny devices are magnetic and can be controlled using an electromagnetic coil system that precisely manipulates the direction and strength of magnetic fields. The researchers hope that their technology could pave the way for tiny surgical robots that could access difficult to reach areas in the body, such as the brain.
Microrobots are a significant focus for researchers at present, and their potential in the biomedical realm is significant. Tiny ro...

Make Some Microbe Friends
By KIM BELLARD
It’s the coolest story I’ve seen in the past few days: The New York Times reported how an Italian museum cleaned its priceless Michelangelo sculptures with an army of bacteria. As Jason Horowitz wrote, “restorers and scientists quietly unleashed microbes with good taste and an enormous appetite on the marbles, intentionally turning the chapel into a bacterial smorgasbord.”
And you just want to kill them all with your hand sanitizers and anti-bacterial soaps.
The Medici Chapel in Florence had the good fortune to be blessed with an abundance of works by Michelangelo, but the ...

Physicians in a quantum state
Despite reading numerous books tailored to the non-physicist, my rudimentary understanding of quantum physics suggests that quantum particles exist in multiple synchronous states and numerous synchronous positions. They are only truly defined upon the observation of that particle. Its nature fluctuates between particles and waves. Schrodinger and his famous thought experiment of the alive/not aliveRead more …Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more.

Subsidizing Research and Technology
Chris EdwardsCongress is considering “The United States Innovation and Competition Act,” which includeslarge new subsidies for research and technology industries. The bill includes $81 billion for the National Science Foundation, $52 billion for semiconductors, and billions for various other programs. President Biden ’s Jobs Plan similarly proposednew subsidies for research and technology.America faces competitive challenges, but a lack of research spending does not seem to be a weakness. Scott Lincicomeshows that U.S. R&D spending has been trending upward in recent decades as a share of the econom...

Coronary physiology update : Why did the “ French FLOWER ” failed to blossom ?
The concept of Fractional flow reserve ( FFR) has dominated the coronary interventional field for over a decade. It gave us a (false) sense of security and pride that we have been advocating physiology-based appropriate stenting.
The much-expected FlOWER-MI trial was presented in ACC & NEJM a week ago. (May 16th Issue 2021)
FFR, though physiologically an attractive concept, has many well-known confounders right from the technical factors, lesion-related errors in physics, mirage of true hyperemia induction with Adenosine, finally & most importantly microvascular dynamism. The value of FFR in the ACS setting w...

Epistemology III: The Scientific Method
Okay, here ' s the dirty secret: there is no such thing. Scientists use many different methods. Some methods are characteristic of certain disciplines, while within disciplines there may be groups of scientists who specialize in or emphasize various methods. This is territory I fear to tread because it can give people some wrong ideas, also because it ' s quite complicated, but I ' ll try to keep it simple and be careful about walling off the wrong ideas.In fact philosophers have found it very difficult to define science, or to clearly distinguish it from non-science or pseudo-science. Despite the pretensions of some, scie...

Epistemology
There are many important things that I know to be true to a moral certainty, that many other people do not believe. I could call these people misinformed or ignorant, but they are just as certain that they are right and I am wrong. There are also innumerable matters of which I am uncertain, but other people do have definite beliefs about them that I know to be wrong. This is a knotty problem indeed, because convincing these people that they are ignorant or misinformed is nearly impossible, and they will certainly never convince me. So the urgent question is, how can I be so certain about these controversial matters? T...

Defining Hypertension : Why we remain in “ Status confusious ” despite 50 years of clinical trials ?
Next to the atmospheric pressure, the most curious pressure to understand is stored within human blood. Yes, it is the “blood pressure”, fondly referred to as BP by both physicians and patients. (When worried men & women visit us and say, that they are suffering from BP, please make it a point to clarify, BP is a sign of existence of life, rather than a dreaded pathology )
Why should blood have pressure?
BP is lateral pressure exerted by flowing blood on the vessel wall (or is it the propelling pressure head ? It is to be noted, cuff pressure doesn’t measure this !) BP is generated by the heart in...

The relation between science achievement and general cognitive abilities in large-scale assessments - ScienceDirect https://www.sciencedirect.com/science/article/pii/S0160289621000131?via%3DihubAbstract Although large-scale assessments (LSA) of school achievement claim to measure domain-specific achievement, they have been criticized for primarily measuring domain-general abilities. Numerous studies provide evidence that LSA of mathematical achievement as well as verbal achievement cover both general cognitive abilities (GCA) and domain-specific achievement dimensions. We extend previous research by analyzing a...
