Transcatheter valvular repair and implantation has become increasingly common for treating patients diagnosed with valvular heart diseases.
0:00 This video summarizes the three transcatheter valvular therapies currently in use in the United States: transcatheter aortic valve implantation (TAVI), transcatheter valve-in-valve procedures, and transcatheter edge-to-edge mitral valve repair.
0:47 Transcatheter aortic valve replacement (TAVI) for patients with severe aortic stenosis regardless of surgical risk 2:47 Transcatheter valve-in-valve procedures for patients with bioprosthetic valve failure
3:35 Transcatheter mitral valve repair for high surgical risk degenerative mitral regurgitation and for severe functional mitral regurgitation regardless of surgical risk.
Colorectal cancer is a leading cancer among men and women around the world. Many colorectal cancers are likely to spread to other organs, with the most common site of metastases being the liver. In this Mayo Clinic Minute, Dr. Sean Cleary, a hepatobiliary and pancreas surgeon at Mayo Clinic explains what this means to patients.
What is Theranostics? Dr. Martin Pomper, Director of the Nuclear Medicine and Molecular Imaging division at Johns Hopkins, describes the mechanisms of a groundbreaking cancer treatment that combines imaging and molecular radiotherapy. With this method, radiopharmaceuticals can specifically target cancer cells while sparing most normal tissues.

Observation is a non-surgical approach in which we allow the stone to pass on its own. The smaller the stone, the better the chance that it will pass. The benefit of observation is that you avoid having surgery.
NYU Langone’s Kimmel Pavilion is home to the region’s newest and most technologically sophisticated neurosurgery suite. Designed to optimize patient care, our facilities are just one reason U.S. News & World Report’s “Best Hospitals” ranks NYU Langone among the top 10 hospitals in the country for neurology and neurosurgery.
Dr. Stacey Rizza, an Mayo Clinic infectious diseases specialist, discusses the various ways COVID-19 is diagnosed and treated.
COVID-19 can be diagnosed several ways when looking for active infection.
“The most common way that testing is done is with a swab into the nose or into the nasal pharyngeal area,” says Dr. Stacey Rizza, a Mayo Clinic infectious diseases expert.
“This polymerase chain reaction (PCR) test is essentially a test looking for the genetic material of the virus.” If it’s positive, it means that person is infected with SARS-CoV-2, the coronavirus that causes COVID-19.
Dr. Stacey Rizza from Mayo Clinic gave the standard Academic recommendations for Covid Testing and treatment. I will comment on how this differs from the testing recommendations of Dr. Michael Mina from the Chan school at Harvard and the actual treatment given to Donald Trump as we speak.
I agree with the latter recommendations, and route that I would opt for, were I to catch Covid 19. TESTING, if it is to be Epidemiologically effective should offer results that are rapidly available so as to reduce spreading of the virus and treatment delay. One trouble with PCR- based tests is that they are slow. Another trouble, according to Dr. Mina, is that if they run for 40 cycles for maximum sensitivity, they may pick up viral shedding that is too minor to be infective, and may cause unnecessary precautions, such as quarantining. If they run for 35 or even 30 cycles to show only infective, actionable cases, they take several days, and even then labs do not usually report the number of cycles run, but only yes or no, positive or negative.
The RAPID TESTS detect viral protein are available within hours. They are less sensitive, but in Dr. Mina’s view, this can be a virtue, since only definitely infected patients are identified. They are cheaper, and can even be done on site. Frequent testing more than makes up for decreased sensitivity. Most tests currently available use only specimens from nasal swabs, which are uncomfortable.
SALIVA is almost as sensitive, and has one additional virtue, when it comes to testing school children. If school children are organized into learning “pods”, They can all spit into a common collector, and the pod tested preemptively, at least twice weekly. If positive The entire pod is individually tested to find who is positive. Of course if a full 20 kids are in a pod, The sensitivity of the protein test may be insufficient for positive to survive a 20-fold dilution, but this can be empirically worked out. Twice weekly testing vs. every other week is much better for reducing the number of the pod members infected at time of discovery, as the NYT has illustrated.
TREATMENT given to Donald Trump has so far consisted of more than Remdesivir. He is also receiving Corticosteroids, plus an experimental double antibody mixture, derived from both Covid Convalescent serum, and monoclonal antibodies from a “humanized” murine source. The antibodies should theoretically be given early. The corticosteroids are generally not given until a bit later, but with the reported drop in O2 sats, he may be later in the disease than we are led to believe. To my knowledge, he is not receiving his tweeted Hydroxychloroquine- azithromycin combination.
If I were infected, at age 88, I would also like the antibody treatment, but most likely would not be allowed to get it.
Fatty liver disease is an increasingly common condition that currently affects a third of the population. The most common cause of the disease is obesity. Extra fat in your body from weight gain accumulates in your liver, causing it to swell. Eventually, the cells in your liver will be so overburdened that they die. New cells grow to replace them, but those cells also contain fat. As liver cells continue to die off and regrow rapidly, it causes scarring of the tissue surrounding the organ.
