Digital Thermography and Machine Learning Team Up to Improve Burn Wound Care
A team at McGill University in Canada and the Universidad Autonoma de San Luis Potosi in Mexico have developed a system for analyzing thermographic scans of burn wounds to improve how they are analyzed and how patients are treated.
The team used digital infrared thermography, a non-invasive imaging technique, to study wounds when they were presented and for the following few days afterward. Infrared thermography shows the heat signature of the tissues being observed, which can indicate a variety of underlying processes taking place, particularly the amount of blood perfusion below the surface. “Digital infrared thermog...

MightySat Rx Cleared by FDA to Measure Breathing Rate from Fingertip
Masimo won FDA clearance for its MightySat Rx fingertip pulse oximeter to be used to spot check the respiration rate. A similar clearance was issued by the European Union regulatory authorities in 2017. These days the breathing rate is still counted manually more often than not. Though there are devices in existence, even contact-free ones, that can measure the breathing rate, they tend to be pricey, designed for bedridden patients, and they can’t be properly used in a variety of settings.
The MightySat Rx uses the company’s Respiration Rate from the Pleth (RRp) technology to measure a patient’s breathin...

Why You Might Need a Dose of Sugar in Your MRI
Sugar could become an effective replacement for metal in contrast agents in magnetic resonance tomography analyses, according to researchers from John Hopkins University and Lund University in Sweden.There has been heated debate over the safety of certain contrast agents, and the Food and Drug Administration has warnedthat gadolinium-based contrast agents (GBCAs) can linger in the brain for months or years after the patient ’s procedure. Using alternatives like sugar could potentially diminish the risk of adverse side effects associated with GBCAs. Studies using animals demonstrated that D-glucose could be a possible b...

iCertainty Contact-Free Perfusion Imaging System Cleared in U.S.
RFPi, a company out of Greenville, North Carolina, won FDA clearance for its iCertainty blood flow and perfusion imaging system. The technology gives clinicians the ability to essentially watch as blood saturates or drains in tissues being worked on, something that typically has to be done using invasive means. The new technology avoids injection of dyes and the use of fluoroscopes that emit ionizing radiation, and may be an alternative to interoperative MRI scanning in some cases.
RFPi believes that many surgical procedures can be done faster, more easily, and with fewer complications, particularly where perfusion imaging...

How to ship a dead heart . . . with an assured life on delivery ?
Human body is intertwined collection of lives of Individual organs.We believe death occurs when brain dies , respiration stops and circulation ceases . Curiously ,when life ends , these organs don’t die as a single unit . These three events can happen in any of the six possible permutations.Each organ takes different times to die after loss of life.It is like a crashed computer , where the mother board /RAM memory may be transferred to another and be functional . Out of these three , heart function appears to be supreme as it can function without the need of brain (Science of brain-death) and keep the body alive w...

The crazy science of coronary reperfusion : When TIMI 1 & 2 beats “ TIMI 3 ” in the myocardial salvage race . . . cardiologists get confused !
The prime job of cardiologists is to restore coronary blood flow in an emergency fashion. While we do this with reasonable success ,there is still a missing link between our Initial aim and achieved goal.
It’s all too common situation in any busy cath lab , to see two similar STEMI patients with identical time window & proximal LAD as IRA , in totally different scenarios. In the first patient we find a trickle of flow in LAD , who is relatively comfortable with normal LV function (In whom , emergency primary PCI might appear redundant.) While the other patient , even after rapidly established TIMI 3 flow , LV...

Fight Aging! Newsletter, December 3rd 2018
This article, however, is more of a commentary on high level strategy and the effects of regulation, coupled with a desire to forge ahead rather than hold back in the matter of treating aging, thus I concur with much more of what is said than is usually the case.
For decades, one of the most debated questions in gerontology was whether aging is a disease or the norm. At present, excellent reasoning suggests aging should be defined as a disease - indeed, aging has been referred to as "normal disease." Aging is the sum of all age-related diseases and this sum is the best biomarker of aging. Aging and its diseases ar...

Tribalism in pain rehabilitation
In this study, female patients and those without prior spine surgery appear to be most likely to benefit from fusion surgery for DDD.” The PCT is essentially a cast around the hips from waist to the top of the leg with a longer leg cast on the side that hurts.
We can see similar appeals to single-factor causal models in studies of core stability – De Blaiser, Roosen, Willems, Danneels, Bossche, & De Ridder (2018) investigating whether this is a risk factor for lower extremity injuries in athletes, while Tayashiki, Mizuno, Kanehisa, & Miyamoto, (2018) investigated the causal effect of intra-abdominal...

Atrophy of the Thymus Accelerates the Progression of Atherosclerosis
The thymus is where T cells mature, the training ground for the footsoldiers of the adaptive immune system. As the thymus declines in size and function with age, the supply of new T cells falls. This constrains and distorts the existing population of T cells, resulting eventually in chronic inflammation and immunosenescence, the failure the immune response and resulting vulnerability to pathogens and cancer. Atherosclerosis, meanwhile, is a condition of the innate immune system, in that it is caused by macrophages - a type of innate immune cell with origins that have nothing to do with the thymus - flocking to try and fail...

Skeletonized internal mammary graft vs pedicled graft
Internal mammary artery (IMA) grafting is an important part of coronary artery bypass grafting. Arterial grafts give longer survival benefits compared to venous grafts. The conventional technique of IMA grafting uses pedicled grafts. Of late, skeletonized grafts are becoming more popular. The proposed advantage of skeletonized grafts is that when bilateral IMA grafts are used, there is less compromise on sternal vascularity and risk of deep sternal infections. Deep sternal infections are always a concern when using bilateral IMA grafts and can occasionally lead to sternal wound dehiscence.
Pedicled graft is harvested en-b...

A completely healthy 30-something woman with acute chest pain -- this post is loaded with info !!!
p.p1 {margin: 0.1px 0.0px 0.1px 0.2px; font: 11.0px Helvetica}A previously healthy young woman presented to the ED with one hour of acute onset right sided chest pain and pressure, very severe, radiating down the right arm. Here is her initial ED ECG (time 0):What do you think?My impression:without any other information, I looked at this ECG and 2 features stood out: 1) the T-wave in lead I is hyperacute. It is far too large for that QRS. 2) The T-wave in V6 is far too large; it is almost as tall as the R-wave, which is distinctly abnormal. 3) there is slight downsloping ST depression in V2 whi...

Coronary artery and veins are married life long . . . with a purpose !
Cardiologist are always worried about the supply side of coronary blood flow. It’s fair enough, we can condone our brain for this one way thinking , afterall arterial supply remain the life-line for the heart. Some of us could (should) realise the importance of these humble coronary veins which are anatomically and physiologically tied together.Its existence is as unique as their arterial counterpart.Coronary blood flow of about 250 ml traverses both the arms every minute.Imagine the scenario if the veins refuse to clear the blood from previous cardiac cycle . . . total hemodynamic chaos right ? Luckily such s...
