Clinical Examination of Cardiovascular System For Medical Students
Discussion on blood pressure is not included here as a separate topic is dedicated to it.
Though the most commonly examined pulse is the radial, to check some of the characteristics, a more proximal pulse like the brachial or carotid needs to be examined. Following parameters of the pulse are routinely documented: 1. The rate: Normal rate in adult is 60-100 per minute. It is higher in children. Younger the child, higher the pulse rate.
Rhythm: Regular and irregular rhythms are possible. Mild variation with respiration is called respiratory sinus arrhythmia, with higher rate in inspiration. Respiratory sinus arrhythmia may...

What do you think of this " Ventricular Bigeminy " ?
Written by Bobby Nicholson MD, with edits by MeyersA woman in her 50s with past medical history of heart failure, prior stroke, atrial fibrillation on Eliquis, lung cancer in remission, and CKD, presented to the emergency department for evaluation of cough and shortness of breath. EKG was obtained in triage and read as ventricular bigeminy. What do you think?On my first read of the EKG, I agreed with the initial interpretation. Pendell Meyers then recommended that I take a second look at the morphology of the QRS complexes. I think it was easiest for me to see in the rhythm strip, but there are clearly P waves in front of ...

How IoT Medical Devices Save and Improve Lives
The following is a guest article by Erik Kling, Interim Head of IoT Americas at Vodafone Business.
IoT, or the Internet of Things, has transformed our homes with connected lights and smart appliances. It’s also revolutionized all areas of business, including manufacturing. Sensors connected to the internet can track goods throughout the supply chain — from sourcing materials to delivering completed products to consumers.
IoT technology has improved the way we live, but its most profound impact may be in healthcare, where it’s saving lives and improving health.
Before IoT revolutionized healthcare, doctors and care pr...

Magnetic Tentacle Robot Travels Deep into Lungs
Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope is use...

Fight Aging! Newsletter, April 12th 2021
In conclusion, the MR exhibited the protective effects against age-related behavioral disorders, which could be partly explained by activating circulating FGF21 and promoting mitochondrial biogenesis, and consequently suppressing the neuroinflammation and oxidative damages. These results demonstrate that FGF21 can be used as a potential nutritional factor in dietary restriction-based strategies for improving cognition associated with neurodegeneration disorders.

Fight Aging! Newsletter, May 6th 2019
This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an ass...

Chronic Inflammation as Proximate Cause of a Large Fraction of Age-Related Disease
This popular science article discusses at length the chronic inflammation that is characteristic of the old, and its role as a proximate cause of age-related disease. Inflammation is a necessary part of the immune response to injury and pathogens, and when present in the short term it is vital to the proper operation of bodily systems. But when the immune system runs awry in later life, and inflammatory processes are constantly running, then this inflammation corrodes metabolism, tissue function, and health.
The causes of excess, constant inflammation are both internal and external to the immune system. Internally, ...

Data Annotators: The Unsung Heroes Of Artificial Intelligence Development
How do you create a smart algorithm? Where and how do you get the data for it? What do you need for a pattern recognizing program to work well and what are the challenges? Nowadays, everyone seems to be building artificial intelligence-based software, also in healthcare, but no one talks about one of the most important aspects of the work: data annotation and the people who are undertaking this time-consuming, rather monotonous task without the flare that usually encircles A.I. Without their dedicated work, it is impossible to develop algorithms, so we thought it is time to sing an ode to the superheroes of algorithm devel...

A 60 year old patient with large T-wave inversions
Written by Andrus Alian and Pendell Meyers, with edits by Steve SmithA female in her 60s with history of stage IV lung cancer presented to the ED with 3/10 chest pain and dyspnea waxing and waning for the last 24 hours. She had no personal or family history of coronary artery disease, drug use, HTN, or dyslipidemia. She did have a history of smoking. She recently had a 2 hour flight. She denied diaphoresis, nausea, or back pain. Vital signs were stable and she was afebrile.Here is her initial ECG (during persistent 3/10 active chest pain):Large T-wave inversions.

Health misinformation in the news: Where does it start?
A new study confirms something we here at HealthNewsReview.org have been emphasizing for many years: Health news stories often overstate the evidence from a new study, inaccurately claiming that one thing causes another — as in drinking alcohol might help you live longer, facial exercises may keep your cheeks perky, and that diet soda might be a direct line to dementia.
The researchers looked at the 50 “most-shared academic articles and media articles covering them” in 2015, according to data from the NewsWhip database. Seven of the 50 studies were randomized controlled trials, the gold standard for “cau...

Real World Evidence (RWE) vs Randomized Control Trials (RCT): The Battle For the Future of Medicine
By DAVID SHAYWITZ, MD
Randomized control trials – RCTs – rose to prominence in the twentieth century as physicians and regulators sought to evaluate rigorously the performance of new medical therapies; by century’s end, RCTs had become, as medical historian Laura Bothwell has noted, “the gold standard of medical knowledge,” occupying the top position of the “methodologic heirarch[y].”
The value of RCTs lies in the random, generally blinded, allocation of patients to treatment or control group, an approach that when properly executed minimizes confounders (based on the presumption that any significant confound...

The Future of Radiology and Artificial Intelligence
What if an algorithm could tell you whether you have cancer based on your CT scan or mammography exam? While I am certain that radiologists’ creative work will be necessary in the future to solve complex issues and supervising diagnostic processes; AI will definitely become part of their daily routine in diagnosing simpler cases and taking over repetitive tasks. So rather than getting threatened by it, we should familiarize with how it could help change the course of radiology for the better.
Radiologists who use AI will replace those who don’t
There is a lot of hype and plenty of fear around artificial intelligence an...
