MiMedx accounting firm quits
The troubles at MiMedx (NSDQ:MDXG) continued last week with the resignation of the accounting firm tapped to audit its books in the wake of a financial scandal. Marietta, Ga.-based MiMedx last July ousted ex-CEO Parker Petit and president & COO William Taylor amid a board-directed independent investigation that had already prompted the departure of CFO Michael Senken and treasurer John Cranston in June.

Predicting leaky heart valves with 3D printing
(Wyss Institute for Biologically Inspired Engineering at Harvard) Researchers at the Wyss Institute have created a novel 3D printing workflow that allows cardiologists to evaluate how different valve sizes will interact with each patient's unique anatomy, before the medical procedure is actually performed. This protocol uses CT scan data to produce physical models of individual patients' aortic valves, in addition to a 'sizer' device to determine the perfect replacement valve size.

Laugh in the Face of Anxiety
Anxiety occasionally visits us all. When we give an important presentation, take a test, go on a first date or walk down a dark alley our minds and bodies naturally respond by going on high alert and attuning to the potential dangers and risks of these endeavors. A healthy amount of anxiety prevents us from falling victim to those dangers and risks. Choosing not to go down that dark alley could be a life-saving response. But an excessive amount of anxiety can increase our risk of suffering negative consequences. The millions of people who suffer from social anxiety disorder, panic disorder, post-traumatic stress disorder...

Global Differences in Out-of-Hospital Cardiac Arrest Reporting
Conclusion Large disparities exist surrounding OHCA patients among three different high-income countries. In addition to this, there are significant gaps in capturing, reporting, sharing and analyzing OHCA data across regional and national borders. Uniformity of reporting standards continue to hinder the epidemiological evidence base for OHCA. Much about OHCA epidemiology is still unknown in many regions of the world, including countries with regional OHCA surveillance in place. These findings present considerable challenges not only nationally, but globally for evaluating the global burden of out-of-hospital cardiac arres...

Whenever we think of countries in Northern Europe we instantly think of sub-zero temperatures, dark clouds and polar landscapes. We also imagine its inhabitants tucked in a bar drinking their sorrows away. What creates this image is the perception that strong spirits and binge drinking are a staple of many Northern countries. However, scientific and factual evidence shows a more nuanced picture. Statistical Verdict The argument that countries with a colder climate e...

It is able to image the entire body using both scanning methods and can produce the image in as little as one second. Over time, Explorer can make videos that can track specially tagged drugs as they move through the body.

Patient's Elevated Airway Pressure Puzzles Providers
Discussion Whether they’re “sensed” through difficulty in ventilating a patient manually via a bag-valve mask or noted because of a ventilator alarm, elevated airway pressures present a risk of harm to the patient. Many ventilators are set to not only alarm at certain airway pressures, but to alter the inspiratory flow delivered to a patient in order to avoid further elevations in airway pressure. This may result in a reduction in the tidal volume delivered to the patient and/or reduced minute ventilation, both of which may result in hypoventilation and resulting hypercapnia. This adjustment, which ventil...

Cultural flies: Conformist social learning in fruitflies predicts long-lasting mate-choice traditions
In this study, we propose a mechanism-driven definition of animal culture and test it in the fruitfly. We found that fruitflies have five cognitive capacities that enable them to transmit mating preferences culturally across generations, potentially fostering persistent traditions (the main marker of culture) in mating preference. A transmission chain experiment validates a model of the emergence of local traditions, indicating that such social transmission may lead initially neutral traits to become adaptive, hence strongly selecting for copying and conformity. Although this situation was suggested decades ago, it previou...
