AI System Spots Prostate Cancer During Routine CT Scans
Researchers at RMIT University in Melbourne, Australia, created an AI system that can identify prostate cancer during routine CT scans. It is typically difficult to spot prostate cancer in CT images, and the radiation makes CT unsuitable as a screening modality. However, if men are undergoing abdominal or pelvic scans for other reasons, this latest system can help spot prostate cancer and let clinicians initiate early treatment.
Prostate cancer remains a significant cause of cancer mortality in men. In Australia, where this technology was developed, prostate cancer is responsible for approximately 12% of male cancer dea...

Modified Blalock-Taussig shunt is:
End to side anastomosis of subclavian artery to a pulmonary artery
Side to side anastomosis of main pulmonary artery to aorta
Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit
Anastomosis of superior vena cava to right pulmonary artery
Correct answer: 3. Side to side anastomosis of subclavian artery to a pulmonary artery using a conduit
In classic Blalock-Taussig shunt, the subclavian artery is divided and anastomosed to the pulmonary artery as an end to side anastomosis. In modified Blalock – Taussig shunt, a Gore – Tex graft is used to connect th...

Fight Aging! Newsletter, June 14th 2021
In conclusion, a number of high-income countries, changes in health expectancies over time have not kept pace with the growth in life expectancy. That is, people are living longer but disability and poor health are occupying an increasing proportion of later life. Our findings suggest that countries still need to make significant progress to achieve the WHO's Decade of Healthy Ageing goal of healthier, longer lives for all.

Athlete ’ s heart
Athlete’s heart
Athlete’s heart denotes structural, functional and electrical remodeling seen in trained athletes. It is a physiological adaptation helping athletes perform physical tasks better than non-athletes [1]. Though most of the findings in athlete’s heart are related to the left ventricle, changes do occur in the right ventricle as well.
Effect of exercise on the left ventricle
During aerobic exercise which is isotonic, the heart rate and stroke volume increases. Systemic vascular resistance falls, but slight to moderate increase in blood pressure can occur due to the increased cardiac output. As...

Athletes Undergoing Regular Strength Training Exhibit Slowed Aging of Bone Tissue
In conclusion, our longitudinal findings indicate that continued strength and sprint training is associated with maintained or even improved tibial properties in middle-aged and older male sprint athletes, suggesting that regular, intensive exercise counteracts bone aging.

Fighting the pandemic : Real war is not against Corona as such !
Caution: Some language
News
It is heartening to note the apex body that is leading the fight against Covid in India, has responded well. It has either recalled or censured many of the Investigations & drugs, procedures that were used in this pandemic. (Not because they are futile, but they also resulted in a meaningless escalation of cost and possibly worsened the outcome)
So, what?
Beware, “non-scientific mutations” are common in medical research even in ordinary times. It is omnipresent now, and no surprise they end up as a premature evidence base. The consequences of this ca...

Non invasive cardiac output monitoring
Conventionally, measurement of cardiac output was done invasively. Initially with dye dilution techniques and later by thermodilution techniques. Both needed pulmonary artery catheterization, which in turn was likely to cause morbidity if used for continuous monitoring. Almost all non-invasive cardiac imaging modalities like echocardiography, computed tomography, magnetic resonance imaging and nuclear imaging can measure cardiac output. But these are not suitable for bedside monitoring, though echocardiography may be used for intermittent bedside assessment.
Assessment of cardiac output though desirable, was most often ti...

Management of aortic dissection
Aortic dissection is the most common aortic emergency. It is one of the three acute aortic syndromes, the others being aortic intramural hematoma and penetrating aortic ulcer. It has a grave prognosis with 20% pre hospital and 30% in hospital mortality. Aortic dissection is generally considered as acute when diagnosis is made within 14 days of onset and chronic after that. An intimal and medial tear in the aorta causes blood to seep into the media and the false lumen usually progresses along a variable extend of the aorta. Important risk factors for aortic dissection are hypertension, Marfan syndrome and bicuspid aortic ...

3D Printed Shields Protect Guts During Radiotherapy
Researchers at Brigham and Women’s Hospital and MIT have developed 3D printed shields to protect the gastrointestinal tract from the side effects of radiotherapy. Using CT scans, the devices can be custom printed to suit each patient’s anatomy. The materials they’re made of contain high atomic number elements that help to shield tissues from gamma and X-rays.
Radiotherapy can be highly effective at targeting tumors and helping to shrink them. However, it can also have significant consequences for nearby healthy tissues. The side effects can be particularly pronounced in the delicate tissues of the mouth and g...

Positron Emission Tomography (PET) in Cardiology
Positron emission tomography (PET) imaging is useful in assessment of myocardial perfusion and viability, atherosclerotic plaque activity as well as cardiac innervation in heart failure. PET is also useful in prosthetic valve endocarditis, endocarditis associated with cardiac implantable electronic devices (CIED), infiltrative cardiomyopathy, aortic stenosis and cardio oncology [1].
PET imaging has superior diagnostic accuracy compared to SPECT (Single Photon Emission Computed Tomography). It has improved spatial and temporal resolution and can measure regional blood flow and has less radiation. In PET, high energy gamma...

The 5 Levels Of Automation In Medicine
“Good morning! How may I help you today?” asks the virtual assistant as you boot your telemedicine app. After experiencing a sore throat and runny nose for a few days, you’ve decided to seek medical attention. You share your symptoms with the assistant who subsequently suggests a cause after scanning its database. “There’s an 83% chance that you are experiencing allergic symptoms,” replies the chatbot. “I will send you your prescription shortly, but if you are not satisfied or still feel unwell, please request for a human physician.”
Considering the likelihood of the diagnosis and the deductive prowess o...

A man in his 50s with acute chest pain and diffuse ST depression
Submitted by Alex Bracey, with edits by Meyers and SmithA man in his 50s with history of type B aortic dissection with prior TEVAR experienced acute onset chest pain at rest and presented to the Emergency Department. Here is his ECG on arrival:What do you think?Here is a prior ECG on file (presumed baseline):There is sinus rhythm with minimal STD in V5, V6, II, III, aVF. There is the tiniest amount of STE in aVL, but the T wave is not hyperacute (instead there is a terminal inversion). I would call this ECG consistent with subendocardial ischemia, but also the question of possible high lateral OMI (for which I am not ...
