  • Sight Restoration Comes into Focus: Versions of Visual Prostheses

    The first visual prosthetic is on the commercial stage now, and a variety of new retinal and cortical implants are in the wings. When it won the European stamp of approval last year, the Argus II became the first commercially available visual prosthesis. Now Second Sight Medical Products Inc. of Sylmar, California, the company behind the Argus II, hopes to receive approval to sell the device in the United States by late 2012. As the excitement over the Argus II continues at a fever pitch, other research groups are developing their own versions of visual prostheses, working to create the potential for restoring sight.

  • Role of the Hippocampus in Memory Formation : Restorative Encoding Memory Integration Neural Device As a Cognitive Neural Prosthesis

    Remind, which stands for “restorative encoding memory integration neural device,” is a Defense Advanced Research Projects Agency (DARPA)-sponsored program to construct the first-ever cognitive prosthesis to replace lost memory function and enhance the existing memory capacity in animals and, ultimately, in humans. Reaching this goal involves understanding something fundamental about the brain that has not been understood previously: how the brain internally codes memories. In developing a hippocampal prosthesis for the rat, we have been able to demonstrate a multiple-input, multiple-output (MIMO) nonlinear model that predicts in real time the spatiotemporal codes for specific memories required for correct performance on a standard learning/memory task, i.e., delayed-nonmatch-to-sample (DNMS) memory. The MIMO model has been tested successfully in a number of contexts; most notably, in animals with a pharmacologically disabled hippocampus, we were able to reinstate long-term memories necessary for correct DNMS behavior by substituting a MIMO model-predicted code, delivered by electrical stimulation to the hippocampus through an array of electrodes, resulting in spatiotemporal hippocampal activity that is normally generated endogenously. We also have shown that delivering the same model-predicted code to electrode-implanted control animals with a normally functioning hippocampus substantially enhances animals memory capacity above control levels. These results in rodents have formed the basis for extending the MIMO model to nonhuman primates; this is now underway as the last step of the REMIND program before developing a MIMO-based cognitive prosthesis for humans.

  • A Digital Health Solution for Using and Managing Medications: Wirelessly Observed Therapy

    Several approaches are currently used to assess medication taking. The most reliable method is directly observed therapy (DOT), which consists of a clinician observing and documenting the date and time of the patient's swallowing each dose of medication. In some cases, this is done by video recording of the patient taking the medication. Other indirect methods for monitoring adherence include patient questioning, patient pill diaries, pill counts, daily weighing of pill containers, and prescription refill rates. Electronically documenting the date and time when the cover of a pill container has been opened is another option. Each of these methods, however, is limited in scope and provides only an estimated measure of actual drug intake, as none of them reliably record whether the patient has actually ingested the medication.

    In the summer of 2006, manufacturers of a simple respirator mask costing US$1 told the U.S. Congress that Americans would find a shortage of these masks if there was another flu pandemic. The reason for this was that suing the makers of these dust masks became a major business for trial lawyers. By 2006, there had been more than 326,000 lawsuits filed. It has been reported in many cases that the law firms worked with cooperative physicians and contracted with X-ray labs to screen individuals for lung problems. If an individual had an abnormal lung X-ray and claimed that they had used a certain brand of respirator and the manufacturer was still in business and had economic resourcesa lawsuit was filed. Some manufacturers went out of business while others simply stopped making the masks. View full abstract»

  • Supporting Clinical Engineering in Italy: Results of a Survey Conducted by the AIIC

    Page(s): 33 - 39

    This article presents the outcomes of a survey developed and conducted by the Italian Association of Clinical Engineers (AIIC) in 2010. The AIIC, affiliated with the International Federation for Medical and Biological Engineering (IFMBE) since 2003, conducted this in-depth survey to investigate the educational profile of clinical engineers (CEs) as well as the activities and organization of clinical engineering departments (CEDs) in Italy.The main purpose of this article is to present Italian clinical engineering activities to international CEs and stakeholders involved in health-care management organizations. The survey data analysis will allow country representatives to identify analogies and differences compared to their status, make healthcare service improvements, and carry out similar surveys in their local context, thereby mapping the state of the art of worldwide clinical engineering.

    In 1990, I was the group leader of Research and Development for Surgitek, a urological device manufacturer in Racine, Wisconsin, which was the market leader in ureteral stents. I recognized the need for an industry standard for ureteral stents, felt that taking a leadership role in the development of a new standard would be a good professional development activity, and volunteered to serve as the chair of the American Society for Testing and Materials (ASTM, now known as ASTM International) Task Group on Ureteral Stents. After several years, the standard was approved, and I continue to serve as the chair of the ASTM Subcommittee on Urological Materials and Devices. This experience helped me understand the value of industry standards, expanded my professional network and visibility within the medical device industry, and helped develop my leadership skills.

  • Ludwig: The Physiologist [Retrospectroscope]

    The thought reproduced in the above epigraph is taken from an article by Thurau et al. [1], who attribute it to Arthur Schopenhauer (17881860), an outstanding philosopher and author of the far-reaching piece Die Welt als Wille und Vorstellung (The World as Will and Representation). In German, it would perhaps read as etwas denken, das niemand vorher gedacht hat, während etwas sehen, was jeder sieht. We could not assert whether Schopenhauer really said that, but it should not be at all surprising if it were, because it sounds simple, perhaps even naïve, and very deep, indeed. It fits perfectly to Carl Friedrich Wilhelm Ludwigs personality (18161895), whom we will look at as physiologist in this second note. Yes, second note—because in the first one [2], we looked at him as bioengineer. A third and last Retrospectroscope column completing this series will deal with his wonderful and always humble and generous activities as teacher. View full abstract»
