Boston Scientific Receives FDA Approval For MR-Conditional Pacing System

Boston Scientific has received U.S. Food and Drug Administration (FDA) approval for a suite of products deemed safe for use in a magnetic resonance imaging (MRI) environment. The ImageReady™ MR-Conditional Pacing System, which includes ACCOLADE™ MRI and ESSENTIO™ MRI pacemakers, as well as the new INGEVITY™ MRI pacing leads, is designed to treat bradycardia, a condition in which the heart beats too slowly. Patients implanted with the full system are able to receive full-body MR scans in 1.5 Tesla environments when conditions of use are met.

The newly-approved family of INGEVITY MRI pacing leads includes active and passive fixation models. This marks the first time a passive fixation pacing lead is approved for U.S. patients undergoing MR scans.

Approval of the INGEVITY MRI leads, as well as the full ImageReady System, was based on data from two global clinical trials. The INGEVITY trial, a prospective, non-randomized study, enrolled 1,036 patients and assessed safety, performance and effectiveness of the leads in patients with a single or dual chamber pacemaker. The SAMURAI trial, a prospective, randomized study, enrolled 351 patients and evaluated safety and effectiveness of the ImageReady System for use in patients with a single or dual chamber pacemaker when used in an MRI environment.

The ImageReady System offers automatic daily monitoring via the LATITUDE™ NXT Patient Management System. An increasingly important tool for physicians, automatic daily monitoring has been shown to improve survival in patients with pacemakers1. The LATITUDE NXT wireless system allows for earlier intervention and improved patient outcomes by providing physicians with device and patient information through customizable alerts.

Microscope uses artificial intelligence to find cancer cells more efficiently

Scientists at the California NanoSystems Institute at UCLA have developed a new technique for identifying cancer cells in blood samples faster and more accurately than the current standard methods.
 
In one common approach to testing for cancer, doctors add biochemicals to blood samples. Those biochemicals attach biological “labels” to the cancer cells, and those labels enable instruments to detect and identify them. However, the biochemicals can damage the cells and render the samples unusable for future analyses.

There are other current techniques that don’t use labeling but can be inaccurate because they identify cancer cells based only on one physical characteristic.

The new technique images cells without destroying them and can identify 16 physical characteristics — including size, granularity and biomass — instead of just one. It combines two components that were invented at UCLA: a photonic time stretch microscope, which is capable of quickly imaging cells in blood samples, and a deep learning computer program that identifies cancer cells with over 95 percent accuracy.

Deep learning is a form of artificial intelligence that uses complex algorithms to extract meaning from data with the goal of achieving accurate decision making.

The new microscope overcomes those challenges using specially designed optics that boost the clarity of the images and simultaneously slow them enough to be detected and digitized at a rate of 36 million images per second. It then uses deep learning to distinguish cancer cells from healthy white blood cells.

The researchers write in the paper that the system could lead to data-driven diagnoses by cells’ physical characteristics, which could allow quicker and earlier diagnoses of cancer, for example, and better understanding of the tumor-specific gene expression in cells, which could facilitate new treatments for disease.

Miniature fluorescence microscopy platform for imaging neural circuits launches commercially

Inscopix has brought its nVista brain imaging platform—which can view upwards of 1000 neurons simultaneously in one field of view—to market. Originally only accessible through the Neuroscience Early Access Program (NEAP), Inscopix plans to expand the system’s reach to the widest spectrum of neuroscience investigators through packages customized for specific researcher needs.

Centered on a patented miniature microscope technology from Stanford University (California), the nVista system can decode the neural language underlying brain function and behavior. With the microscope, a tiny fluorescence camera can be implanted in hard-to-reach areas of a freely moving animal’s brain and record millisecond-by-millisecond movies of the activity of large neural networks over days or several months.

Since the launch of NEAP in 2012, Inscopix disseminated nVista to over 100 early-adopter labs that played a crucial role in maturing the platform through feedback and scientific validation for its incorporation into standard neuroscience practice. NEAP researchers have published close to 20 research articles with the system in journals such as Neuron,Nature, and Cell, that provided deeper insights into multiple aspects of brain function, including motivation, learning and memory, and goal-directed behaviors. nVista also led to Inscopix’s recognition by the World Economic Forum as a “Technology Pioneer” in 2015.

Planmed digital breast tomosynthesis system receives CE mark

The Planmed Clarity 3D digital breast tomosynthesis system and the Planmed Clarity™ 2D full field digital mammography system have received the CE mark and are now available for sale in the EU and other countries where the CE mark applies. The systems have also won the prestigious Red Dot Design Award.

Digital breast tomosynthesis produces a 3D volume of the breast and resolves the challenge of overlapping tissue structures. This results in enhanced diagnostics, especially for patients with denser breast tissue. Planmed’s patented new tomosynthesis method significantly improves image accuracy and allows even the smallest details to be captured with great precision.

In addition to the Planmed Clarity 3D digital breast tomosynthesis system, the new product family also includes the Planmed Clarity 2D digital mammography system, which can be easily upgraded to digital breast tomosynthesis at any time. Both systems allow imaging with a low effective patient dose and feature a durable digital detector for mobile screenings, as well as the new Planmed Clarity Flow touch control with dual touchscreens.

Brain stimulation may reduce anorexia symptoms

Core symptoms of anorexia nervosa, including the urge to restrict food intake and feeling fat, are reduced after just one session of a non-invasive brain stimulation technique, according to King’s College London Research.

This new study is the first randomised control trial to assess whether repetitive transcranial stimulation (rTMS), already an approved treatment for depression, is also effective in reducing symptoms of anorexia.

Up to 20 per cent of people with anorexia die prematurely from the disorder and treatments in adults are moderately effective, with only 20-30 per cent of people recovering from the best available talking therapies.

Given the urgent need to improve treatments, researchers are increasingly looking towards emerging neuroscience-based technologies that could target the underlying neural basis of anorexia.

In the study, 49 people completed food exposure and decision-making tasks, both before and after a session of either real or placebo rTMS. Symptoms of anorexia were measured immediately prior to and following rTMS, as well as 20 minutes and 24 hours after the session.

This study represents independent research part-funded by the National Institute for Health Research (NIHR) Biomedical Research Centre (BRC) at South London and Maudsley NHS Foundation Trust and King’s College London.
