Abbott Expands Portfolio of MRI-Ready Devices

Wed, 03 Jan 2018 19:20:18 +0100

FDA gave MR-conditional labeling to two of Abbott's cardiac rhythm management (CRM) devices, a move that further boosts the company's ability to compete with its peers in the space. The Abbott Park, IL-based firm said patients who receive a Quadra Assura MP cardiac resynchronization therapy defibrillator (CRT-D) or a Fortify Assura implantable cardioverter defibrillator (ICD) are now able to have an MRI in the future if need be. The Quadra Assura and the Fortify Assura are two of Abbott's most widely-used high voltage devices, the company noted. In September 2016, Abbott won FDA approval for MR-conditional labeling for the Ellipse ICD, which represented the first major step toward closing an important gap that previously existed in St. Jude's portfolio, prior to Abbott and St. Jude merging...



The 8th Annual Alexander Awards: The Best Tox Reading of 2017

Tue, 02 Jan 2018 21:17:32 +0100

Alexander Gettler Once again, last year’s outstanding examples of long-form journalism dealing with topics related to medical toxicology were dominated by coverage of the opioid crisis, its origins and the resulting carnage. The must-read article of the year was “The Family That Built a Empire of Pain,” Patrick Radden Keefe’s massive history of the Sacklers, one of America’s richest clans, much of whose wealth comes from their ownership of Purdue Pharma and the marketing and distribution of Oxycontin. The article, which appeared in the New Yorker, notes that the clan’s patriarch, Arthur Sackler, worked his way through medical school in the 1940s by serving as a copywriter for a New York ad agency that targeted targeted physicians and medical workers.

Getting to the heart of mapping arrhythmia-related excitations

Fri, 29 Sep 2017 04:00:00 +0100

(American Institute of Physics) Atrial fibrillation is the most prevalent form of cardiac arrhythmia, affecting up to 6 million people in the US alone. Common treatments for severe forms of the erratic beating phenomenon are controversial, and guided by detection methods that are not yet standardized or fully refined. But research from a group of cross-disciplinary scientists, published this week in the journal Chaos, offers a computational approach to understanding the important factors involved in measuring cardiac excitation waves.

Abbott Catches Up to Peers With MRI-Compatible ICD

Sat, 23 Sep 2017 04:38:19 +0100

Abbott Laboratories acquired St. Jude Medical earlier this year knowing that the company trailed behind its peers in the cardiac rhythm management (CRM) space by not having a MRI-compatible pacemaker or implantable cardioverter defibrillator (ICD) system. It seems Abbott has officially caught up in that category though, first with FDA approval of the Assurity MRI pacemaker and the Tendril MRI pacing lead during the first quarter, and now with FDA approval of MRI-conditional labeling for the Ellipse ICD system. Abbott said the recent approval covers one of its most widely-used ICD systems and associated high voltage leads. The approval is for the Ellipse ICD with the Tendril MRI pacing lead and Durata and Optisure high voltage leads. The new labeling allows patients with an Ellipse ICD pati...

Not all astrocytes in the brain are the same, study finds

Thu, 13 Jul 2017 16:53:00 +0100

From afar, the billions of stars in our galaxy look indistinguishable, just as the billions of star-shaped astrocytes in our brains appear the same as each other. But UCLA researchers have now revealed that astrocytes, a type of brain cell that supports and protects neurons, aren ’t all the same. While stars might be categorized by their size, age and heat, the supportive brain cells vary when it comes to shape, molecular machinery and functioning.The findings,published today in the journal  Neuron, should make it easier for researchers to study how astrocytes relate to disease, or to develop drugs that aim to target small subsets of astrocytes, said Baljit Khakh, a UCLA professor of physiology and neurobiology and the study’s senior author.“For 50 years, the textbooks have said th...

Binge drinking could trigger abnormal heart rhythms

Thu, 27 Apr 2017 17:29:16 +0100

Conclusion This cross-sectional study found binge drinking is associated with an increased risk of having an irregular heartbeat. However, the type of irregular heartbeat found was mainly sinus tachycardia, which isn't life threatening but involves the heart beating at an abnormally fast rate of over 100 heartbeats a minute. This research also has some notable limitations: The ECG recordings from the acute alcohol group were taken using a smartphone application operated outside the manufacturer's recommended environment. The lively atmosphere within the beer tent may have caused inaccurate recordings. The population recruited from Oktoberfest was varied in ethnic origin and only 69% were from Germany – it may not be appropriate to compare them with the KORA community population, w...

Hypothermia Diagnosis and Treatment Could Save Lives

Fri, 13 Jan 2017 20:37:28 +0100

Hypothermia is a life threatening condition that may result in death. It is a drop in the core body temperature of less than 95°F (35° Celsius). This temperature is below what is required for normal metabolism and bodily function (Figure 1). The normal body temperature is between 97.7°F and 99.5°F (Fahrenheit) which is the same as 36.5°C and 37.5°C (Celsius). The body's thermoregulation mechanism adjusts to weather changes. Thermoregulation During extreme cold, the body receives a signal from sensory receptors. The signal will go up to the brain. The brain then sends a signal to the body to respond to the cold temperatures and attempts to maintain the core body temperature (Figure 2). This is necessary in order to provide the vital organs with the necessary heat to function prope...

Light-based arrhythmia treatment skips the shocks

Wed, 14 Sep 2016 13:58:34 +0100

Researchers at Johns Hopkins University and Germany’s University of Bonn showed that light can restore a normal heartbeat and replace electric shocks in patients at risk for arrhythmia, according to a press release from the Baltimore school. The work was published online yesterday in the Journal of Clinical Investigations and could 1 day be used to develop implantable defibrillators, the team suggested. A standard defibrillator uses electrical shocks to jump-start the heart when a patient experiences arrhythmia, a potentially deadly irregular heartbeat. The shocks can be painful and damage the heart tissue. Researchers at the University of Bonn turned to the emerging field of optogenetics, which uses light-sensitive proteins to modify electrical activity in cells. The Bonn team used beat...

What Causes Hyperphosphatemia?

Mon, 12 Sep 2016 00:49:32 +0100

Discussion Constipation is a common problem in general pediatrics and its causes are numerous. It can cause acute and recurrent abdominal pain and is a cause of abdominal distention. Patients who are young, whose presentations are other than routine or who had complications should be invested for underlying causes of their constipation. This patient had undergone some evaluations in the past for constipation but because of the presentation of sepsis a more rigorous evaluation was undertaken. The differential diagnoses of the following can be found here: constipation, acute abdominal pain, recurrent abdominal pain, and abdominal distention. Hyperphosphatemia caused by retention of oral phosphate containing medications and hypertonic sodium phosphate enemas are known causes of hyperphosphat...



[In Depth] A painstaking overhaul for cardiac safety testing

Thu, 01 Sep 2016 22:00:00 +0100

It's a crucial step in drug development: testing a compound to gauge whether it might cause cardiac arrhythmia. For years, researchers and drug developers have worried that standard preclinical tests for cardiac safety are actually too conservative, and may lead drugmakers to abandon promising and safe treatments early in development. Since 2013, an international team of regulators, academic researchers, and drug companies have been validating a more sophisticated set of tests, known as the Comprehensive in vitro Proarrhythmia Assay (CiPA). That painstaking process is inching toward completion. In the coming weeks, a key component of that assay, based on stem cell–derived heart cells, will undergo blind testing on drugs with known risks at various academic and industry labs, and the CiPA...

What Your Tongue And Tonsils Could Tell You About Your Sleeping Habits

Wed, 09 Mar 2016 19:08:39 +0100

Your dentist might be able to tell if you're having trouble sleeping.  Yes. A new study published in the Saudi Medical Journal found that the size of a person's tonsils may indicate their risk for obstructive sleep apnea, a condition in which blocked upper airways cause breathing to stop and restart repeatedly during sleep. Tongue indentations, or teeth imprints on the tongue that suggest it's too big for the mouth, may also be a sign.  More than 18 million adults in the United States are affected by OSA. Since people with the condition are often suffering from interrupted and reduced sleep, it can lead to fatigue, irritability, and trouble concentrating. In severe cases, the disorder can lead to learning and memory difficulties, heart attack, congestive heart failure, card...

Here's Some Good News About Coffee And Your Heart

Wed, 27 Jan 2016 21:27:57 +0100

Sip your coffee with peace of mind: A new study published in the Journal of the American Heart Association has found that caffeine doesn't cause heartbeat irregularities, despite what we've heard in the past. Researchers at the University of California San Fransisco assessed the coffee, tea and chocolate intake of 1,388 healthy men and women over a year-long period. During this time, participants also wore a portable device that monitored their heart rhythm 24 hours a day.  Sixty-one percent of participants reported drinking or eating more than one caffeinated item every day, yet the heartbeat monitors did not detect extra heartbeats in those who ingested higher amounts of caffeine. This led researchers to conclude that caffeine intake has little effect on heartbeat. Why is this impo...

4 out of 5 stars Flumazenil, naloxone and the ‘coma cocktail’ Sivilotti MLA Br J Clin Pharmacol 2015 Aug 7 [Epub ahead of print] Abstract This very smart paper reviews factors affecting the clinical use of two antidotes that reliably reverse  coma caused by two major classes of poisons: flumazenil for benzodiazepines, and naloxone for opiates. Both these antidotes are specific, rapid-acting, short-lived, and titratable. However, significant adverse effects have been associated with each of them. Unwise or overly aggressive administration of flumazenil can cause acute benzodiazepine withdrawal, agitation, seizures, and fatal cardiac arrhythmias. Since many of the severe adverse effects occur in cases of mixed overdoses, use is generally discouraged in the comatose poisoned pat...

Biotronik launches 2 new studies

Wed, 12 Aug 2015 15:24:46 +0100

Biotronik announced 2 new studies last week that are slated to examine the company’s CRT-D device and BioMonitor implanted cardiac monitor. A 277-patient BioContinue clinical trial will examine the risk of ventricular arrhythmias after CRT-D replacement, enrolling patients over 2 years at 40 centers across 8 countries, the company said. Biotronik said the trial will be the 1st to investigate defibrillator back-up following device placement in heart failure patients with a primary indication for cardiac resynchronization therapy defibrillators. Patients in the trial will be implanted with Biotronik’s CRT-Ds and assessed for the rate of ventricular tachyarrhythmias over 2 years. Biotronik said that it looks to evaluate the risk of VTA or ventricular fibrillation after replacement...

SentreHeart wins FDA nod for Lariat trial

Fri, 26 Jun 2015 12:00:00 +0100

SentreHeart said yesterday it won FDA investigational device exemption approval to begin enrolling subjects in a clinical trial of its Lariat device. The Amaze trial will evaluate the use of the Lariat for the ligation of the left atrial appendage as an adjunctive treatment to ablation in patients with persistent atrial fibrillation, the company said. “The LAA is an important site for atrial fibrillation initiation and persistence, and its exclusion using the Lariat device as an adjunct to conventional ablation could be a major breakthrough in decreasing recurrence in patients with persistent atrial fibrillation. The Amaze trial is rigorously designed and we believe will further validate the mechanical and electrical isolation benefits of the Lariat device, which has the potential t...



Consensus paper on patient preferences for arrhythmias management published

Wed, 24 Jun 2015 14:02:42 +0100

A unique consensus paper on patient preferences for arrhythmias management has been published. Cardiac arrhythmias can have a big impact on quality of life. Patients with ventricular arrhythmias, for example, may be banned from sports and driving. Those with an implantable cardioverter defibrillator (ICD) need to weigh the longevity they would gain with the device against the potential for a protracted death from progressive heart failure when deciding whether or not to have it switched off towards the end of life.

6 Human Foods You Should Never Feed Your Cat

Wed, 24 Jun 2015 11:00:19 +0100

His tiny whiskers and swishy tail are so sweet it can be hard to resist giving him whatever he wants, but there are certain foods you should never feed your cat. Many human foods can put your little guy at risk for gastrointestinal problems, restlessness and worse. As the devoted pet owner that you are, the safest bet is to teach your cat that the food on the dinner table is for people only, and the food in his bowl can be enjoyed to the fullest. There are certain human treats you and your cat can share -- really small servings of cooked vegetables and fish are OK for kitties, for example. But when in doubt, it's best to stick to the veterinarian-approved eats, and to always consult your vet before introducing something new into your pawed pal's diet. Best Friends Animal Society, a Utah an...

My Conversation With Sleep Apnea Expert Richard Schwab

Tue, 28 Apr 2015 16:26:13 +0100

Dr. Richard Schwab is a professor of medicine at the Hospital of the University of Pennsylvania. His groundbreaking research has used innovative imaging techniques to study the development of sleep apnea (when tissues in the mouth close during sleep, resulting in repeated airway obstructions and associated oxygen drops). In our conversation, he shared his insights on the most important facts in sleep apnea research: the high prevalence of the disorder, how obesity and alcohol can cause sleep apnea, the resulting cardiovascular problems, and the importance and ease of treatments. Here is a lightly edited transcript of our conversation. What are the primary risk factors and consequences of sleep apnea? The big-picture message: Sleep apnea is really common. More than 18 million Americans su...
