There are all sorts of different vaccines but many of them share specific types of ingredients. Josh Toussaint-Strauss talks to Professor Adam Finn to find out what is in most conventional vaccines, as well as what they do to our bodies when we take them – and why the mRNA Covid jabs from Pfizer/BioNTech, Oxford/AstraZeneca and Moderna work differently.

PHYSICIAN Q&A: SCREENING FOR COLORECTAL CANCER
Colorectal cancer is comprised of colon cancer and rectal cancer, which originate in the lower portion of the large intestine and into the rectum. As with other cancers, screening for early detection should not be delayed. “The vast majority of the time, we don’t know exactly what causes any specific cancer,” says Dr. Jeremy Jones, a Mayo Clinic oncologist. “But there are a number of factors that can increase the risk of developing colon or rectal cancer.” Dr. Jones says one risk factor is increasing age. However, he adds that over the last 30 years younger patients have seen a 50% increased risk of developing colon and rectal cancers. In this Mayo Clinic Q&A podcast, Dr. Jones talks about risk factors, symptoms, treatment, health care disparities and the latest in colorectal cancer research. ____________________________________________
COVID-19: ‘WHY VARIANTS ARE SPREADING FASTER’
As highly transmissible coronavirus variants sweep across the world, scientists are racing to understand why these new versions of the virus are spreading faster, and what this could mean for vaccine efforts. New research says the key may be the spike protein, which gives the coronavirus its unmistakable shape. Illustration: Nick Collingwood/WSJ
Technology: Augmented Reality Improves Spine Surgery Outcomes (Video)
Kay suffered from debilitating muscle cramping and lower back pain due to spondylolisthesis, a common condition in the lumbar spine. When nonsurgical treatment options failed, she turned to spine neurosurgeon Timothy Witham for help. He used a new augmented reality technology to accurately place spinal instrumentation in her back. Seven months after surgery, Kay has resumed her daily pursuits without pain and is enjoying life.
MEDICAL RESEARCH: ‘NEXT GENERATION VACCINES’
Vaccine science and technology is advancing. Next generation vaccines could change how we combat infectious diseases, and it’s important to understand how the technology works.
COVID-19: PENN MEDICINE EXPLAINS MRNA VACCINES
Vaccines are about to change the world…again. mRNA Vaccines are currently being used to battle COVID-19, and have the potential to eradicate diseases like HIV, herpes, sickle cell anemia, and even cancer. Learn how the vaccines work and where the technology could be headed in this explainer video.
Heart Failure: ‘What It Is & How To Treat It’ (Video)
The heart is a hero. It works relentlessly to deliver oxygen and nutrients to the body. But just like all heroes, sometimes it gets tired, and can’t do its job as well. This is called heart failure – the inability for the heart to pump enough blood and oxygen to the lungs and rest of the body. In this video, Northwestern Medicine cardiologists Clyde W. Yancy, MD, MSc and Jane E. Wilcox, MD, MSc explain what heart failure is and the integrated and collaborative approach used to diagnose, stage and treat heart failure at Northwestern Medicine.

EXERCISE: BENEFITS OF HIIT (HIGH-INTENSITY INTERVAL TRAINING) – MAYO CLINIC
Mayo Clinic Division of Preventive Cardiology will be preparing a series of recordings focusing on Cardiovascular Disease states. This is the Exercise Series and this particular one focuses on HIIT and its benefits. Results in physiological adaptations linked to improved health (even with a very small volume of exercise).

YALE MEDICINE: ‘WHAT CAUSES HEART FAILURE?’
The heart is a muscle and it’s main job is to pump blood but certain things can cause that muscle to fail. There are genetic reasons, there are reasons related to valve disease, and there’s a viral infection that affects the heart called myocarditis.
The most common cause of heart failure is a heart attack. Fatty plaque builds up in the blood vessel that supplies the heart itself and unless that blood vessel is opened up immediately that muscle will die. The rest of the muscle that’s not dead anymore has to do extra to keep on pumping the blood and overtime it cannot keep and that’s when heart failure develops.
