MedicalResearch.com Interview with: Shelly Levy-Tzedek, PhD Head of the Cognition, Aging and Rehabilitation Lab Faculty of Health Sciences, Dept. of Physical Therapy & The Zlotowski Center for Neuroscience The Ben Gurion University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Following brain injury, patients who need to practice their physical therapy exercises at home. Many don’t practice enough or at all at home, and so we are designing robot companions to encourage them to practice and to track their progress. This study is a first step towards this goal. Here, we studied how people played a leader-follower mirror game with a robotic arm, where a person and robot took turns following each other's joint movements patterns. When the robotic arm was leading, it performed movements that were either sharp, like dribbling a ball, or smooth, like tracing a circle. (more…)

Author Interviews, PTSD, Technology / 17.10.2017

MedicalResearch.com Interview with: Dr. Gale Lucas, PhD Director of Research USC Institute for Creative Technologies Playa Vista, CA   MedicalResearch.com: What is the background for this study? What are the main findings? Response: A common barrier to healthcare for psychiatric conditions is the stigma associated with these disorders. Perceived stigma prevents many from reporting their symptoms. Stigma is a particularly pervasive problem among military service members, preventing them from reporting symptoms of combat-related conditions like posttraumatic stress disorder (PTSD). This put them at risk for having their symptoms go untreated, with possible disastrous outcomes including suicide attempts. We envisioned a technology system – a virtual human interviewer – whereby military service members can get feedback about their risk for PTSD in a safe place without stigma. Indeed, our prior research has shown that, because its “just a computer” (therefore safe and anonymous), this virtual human interviewer helps people to feel safe discussing sensitive issues like mental health symptoms. In this follow-up research project (published in Frontiers), we sought to demonstrate the value of this kind of virtual human interviewer specifically for encouraging reporting of PTSD symptoms among service members. Specifically, we were interested in comparing the willingness of service members to report symptoms of PTSD to our virtual human interviewer, compared to the gold standard of the Post Deployment Health Assessment (PDHA). We wanted to isolate the effect of anonymity, separating it from “relational factors” that the virtual human interviewer uses to encourage service members to open up. Indeed, before asking these same questions as on the PDHA to capture PTSD symptoms, the system engages in social dialogue, which build rapport with users. The system asks “get to know you questions,” and throughout the interview, engage in active listening with responses such as nods, smiles, saying “uh huh,” and other encouraging phrases like “that’s great.” (more…)
Asthma, Author Interviews, Technology / 16.10.2017

MedicalResearch.com Interview with: Frank Trudo, MD, MBA Brand Medical Lead US Respiratory AstraZeneca MedicalResearch.com: Would you tell us about Lungprint?  How will Lungprint help asthma patients take better control of their disease? Response: Lungprint is an interactive digital tool that creates a dynamic visual representation of a person’s lungs based on their unique experiences with asthma. It is meant to provide people with asthma a better understanding of the role of asthma in their life and motivate them to have a more personalized conversation with their healthcare provider about the severity of their symptoms, a more individualized treatment plan and a blood test that measures eosinophil levels. Each person’s Lungprint, which is generated as they respond to a digital questionnaire about their experience with asthma, will help reveal information about their individual experience with asthma. You can visit www.lungprint.com to learn more about the tool and create your own Lungprint.  (more…)
Author Interviews, Emergency Care, Infections, Pediatrics, Technology / 19.09.2017

MedicalResearch.com Interview with: Prof. Alain Gervaix Head of the Emergency Division Department of Children and Adolescents University Hospitals of Geneva Switzerland MedicalResearch.com: What is the background for this study? Response: Many are familiar with the following ‘seemingly’ simple clinical dilemma that occurs on a daily basis across the world. A patient visits the doctor with a fever. Commonly, assigning a diagnosis comes down to deciding whether the infection is bacterial or viral. Accordingly, the doctor decides if to treat or not to treat with antibiotics. The problem is that bacterial and viral infections often present with very similar symptoms, causing uncertainty that leads to antibiotics being used, in many instances, when they are not needed. This antibiotic misuse contributes to the rise of antimicrobial resistance, one of the biggest health threats of the 21st century. Host biomarkers hold great promise as routine diagnostic tools that can assist doctors in making correct antibiotic treatment decisions, as they overcome key limitations of currently applied pathogen-based tests. Recently, a novel host-assay (ImmunoXpert™) for differentiating bacterial from viral infections was developed and validated to yield high sensitivity and specificity. The three-protein host-assay comprises tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), Interferon gamma-induced protein-10 (IP-10) and C-reactive protein (CRP). (more…)
Allergies, Author Interviews, Brigham & Women's - Harvard, Pediatrics, Technology / 07.09.2017

MedicalResearch.com Interview with: Lee, Hakho, PhD Department of Systems Biology Harvard Medical School Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: The incidence of food allergy is increasing worldwide, particularly among children, and yet no handy test is available for general public. There are plenty of allergens testing methods for the factories producing the products, we wanted to solve this issue. Our pilot test showed wide variation in allergen contents in packaged food products and restaurant meals. Hidden allergens (like gluten in salad dressing, likely from additives) were also found.

MedicalResearch.com Interview with: Ken Long, MD/PhD student Department of Bioengineering Micro and Nano Technology Laboratory University of Illinois at Urbana-Champaign Urbana, Illinois MedicalResearch.com: What is the background for this study? What are the main findings? Response: Traditional laboratory-based spectrometers are a mainstay of clinical diagnostics.  In our recent Lab on a Chip article we sought to produce a handheld device that would be able to perform three broad classes of spectrometric tests that one might normally do in a laboratory (Transmission-based, Reflection-based, and Intensity-based) on a smartphone-based handheld device that could be used at the point-of-care. Using high-resolution 3D printing, a custom optical fiber, and some off-the-shelf lenses, we were able to design, assemble, and demonstrate a device capable of reproducing results of traditional benchtop equipment when measuring results from commercially-available tests.  The device is small enough to hold in the palm of your hand, cost less than $550 to build the prototype, and has the ability to read multiple tests using the video-capture capabilities of the smartphone and a swiping motion with liquid test cartridges, much like swiping a credit card through a reader.  The two tests demonstrated in the paper were for a biomarker associated with pre-term birth in pregnant women, and a PKU test for newborns that can defect a critical nutritional enzyme deficiency.

Author Interviews, Psychological Science, Technology / 07.08.2017

MedicalResearch.com Interview with: Mag. Nicole Mirnig  Research Fellow Center for Human-Computer Interaction University of Salzburg Salzburg, Austria  MedicalResearch.com: What is the background for this study? What are the main findings? Response: From our previous research on social robots, we know that humans show observable reactions when a robot makes an error. These findings result from a video analysis we performed over a large data corpus from different human-robot interaction studies. With the study at hand, we wanted to replicate this effect in the lab in order to explore into more detail how humans react and what they think about a robot that makes a mistake. Our main findings made us quite excited. First of all, we could show that humans respond to faulty robot behavior with social signals. Second, we found that the error-prone robot was perceived as significantly more likeable than the flawless robot. One possible explanation for this finding would be the following. Research has shown that people form their opinions and expectations about robots to a substantial proportion on what they learn from the media. Those media entail movies in which robots are often portrayed as perfectly functioning entities (good or evil). Upon interacting with a social robot themselves, people adjust their opinions and expectations based on their interaction experience. We assume that interacting with a robot that makes mistakes, makes us feel closer and less inferior to technology. (more…)

MedicalResearch.com Interview with: Bertrand LAPERGUE, MD, PhD Hôpital Foch, University Versailles Saint Quentin en Yvelynes Department of Stroke Center, Diagnostic and Interventional Neuroradiology Suresnes, France. Michel PIOTIN, MD Department of Diagnostic and Interventional Neuroradiology Fondation Rothschild, Paris, France. on behalf of the ASTER Trial Investigators. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Mechanical thrombectomy (MT) with a stent retriever (SR), in association with intravenous (IV) rtPA, is now the standard of care in anterior circulation ischemic stroke caused by large vessel occlusion (LVO). Favorable outcome is strongly associated with the successful reperfusion status (TICI 2b/3= 71% with SR, Hermes Study group). New techniques for MT such as ADAPT (A Direct first pass Aspiration Technique) seem promising to increase reperfusion status and clinical outcome in retrospective studies. (more…)

MedicalResearch.com Interview Provided on behalf of: Jan Janssen, Senior Vice President Research and Development Cochlear LimitedJan Janssen, Senior Vice President Research and Development Cochlear Limited MedicalResearch.com: What is the background for this device? Response: Cochlear implants treat hearing loss by electrical stimulation of the hearing nerve, bypassing the damaged parts of the hearing pathway. Cochlear implants system consist out of an external sound processor that detects and processes the sounds and then sends them to the implant. The implant receives this information and turns it into electrical signals that are delivered to the hearing nerve and from there to the brain. The Nucleus® 7 Sound Processor is the world’s first and only Made for iPhone cochlear implant sound processor, allowing users to stream sound from their iPhone®, iPad® and iPod touch® directly to their cochlear implant sound processor. It not only enhances the experience of talking on the phone, it also makes features like enjoying music or watching videos, as well as audio apps such as Maps or FaceTime, more easily accessible. The Nucleus 7 Sound Processor is also the smallest and lightest behind-the-ear sound processor on the market. (more…)

MedicalResearch.com Interview with: Dr Ian Williams PhD Associate Professor, DMT Lab Birmingham City University Faculty of Computing, Engineering and the Built Environment Centre for Digital Media Technology Millennium Point Birmingham UK MedicalResearch.com: What is the background for your work? Response: Our work at the DMT Lab (dmtlab.bcu.ac.uk) focuses on developing a novel Mixed Reality (MR) medical presentation platform which allows practitioners to interact with patient data and virtual anatomical models in real time. The system enables the presentation of medical data, models and procedures to patients with the aim of educating them on pending procedures or the effects of lifestyle choices (for example the effects of smoking or excessive alcohol consumption). The system employs an exocentric mixed reality environment which can be deployed in any room. It integrates a medical practitioner in real time with multimodal patient data and the corresponding result is a real time co-located visualisation of both the practitioner and the data, which they can interact with in real time.  We implement a natural interaction method into the system which improves a user’s level of direct interaction with the virtual models and provides a more realistic control of the data. The system can also be used in a fun educational setting where patients, students, children or any naive user, can learn about medical anatomical information via a real-time interactive mixed reality “body scanner”. This fun system overlays the MR information onto their own body in real-time and shows them scaled and interactive virtual organs, anatomy and corresponding medical information. We are aiming for this system to be used not only in patient education but also in engaging and informing people on lifestyle choices. (more…)
Author Interviews, Exercise - Fitness, Technology / 10.07.2017

MedicalResearch.com Interview with: Jacob Barkley, Ph.D., College of Education, Health and Human Services Kent State  MedicalResearch.com: What is the background for this study? Response: Our group has demonstrated that cellular telephone (cell phone) use is positively associated with sedentary behavior (i.e., sitting). To that end, high cell phone users sit for 80 to 100 minutes longer than their lower-use peers. We have also shown that cell phone use during exercise decreases exercise intensity and slows free-living walking speed. In other words, cell use may be comparable to traditional sedentary screen use in that it promotes sitting and may interfere with physical activity. However, some cell phone functions may actually promote positive health behaviors. Fitness apps, connecting with active peers and administering health recommendations via the cell phone all may have utility in promoting physical activity and reducing sedentary behavior. While not well studied, novel physically-interactive cell phone games may also promote physical activity. One such game, Pokémon Go! requires users to walk through real environments and locate avatars in the game using GPS. The purpose of the game is to find these avatars. In order to find more avatars, the player will need to walk to more areas. Therefore, playing Pokémon Go! may promote walking. (more…)

MedicalResearch.com Interview with: Leon Sütfeld The Institute of Cognitive Science University of Osnabrück  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Self-driving cars, and especially future fully autonomous cars, pose a number of ethical challenges. One of these challenges is making the "right" decision when it comes to a so-called dilemma situation, in which a collision is unavoidable (or highly probable), but a decision can be made as to which of multiple different collisions to choose. Our study assesses the behavior of human participants in such dilemma situations and evaluates algorithmic models that are trained on this data to make predictions. Our main findings are that in a controlled virtual reality environment, the decisions of humans are fairly consistent and can be well described by simple value-of-life models. (more…)
Author Interviews, Cancer Research, Dermatology, JAMA, University of Pennsylvania / 06.07.2017

MedicalResearch.com Interview with: Mackenzie R. Wehner, MD, MPhil Department of Dermatology University of Pennsylvania Philadelphia, PA MedicalResearch.com: What is the background for this study? Response: For some diseases, we have national registries, in which information about every person with that disease is entered for research purposes. For other diseases, unfortunately, we do not have such registries. There are growing opportunities to use information like internet searches to better understand behaviors and diseases, however. Our study was a proof-of-concept: we aimed to find out whether internet searches for diseases correlated with known incidence (how many people are diagnosed with the disease) and mortality (how many people die of the disease) rates. E.g. does the number of people who searched 'lung cancer' online correlate with the number of people who we know were diagnosed with or who died of lung cancer during that same time period? This is important to know if researchers in the future want to use internet search data for diseases where we lack registry information. (more…)

What are the main findings? Response: Essential Tremor is treated using Deep Brain Stimulation (DBS) in some patients. Current clinical practice involves Deep Brain Stimulation with an "always on" stimulation. This causes extra battery drain, because stimulation is applied when not needed. Also excessive stimulation is not necessarily a good thing, Our work is aimed at adjusting the stimulation, so that it comes on and turns off only when needed to suppress tremor symptoms. (more…)
Addiction, Author Interviews, Technology / 24.06.2017

MedicalResearch.com Interview with: Dr. Phil Reed,  D.Phil. Professor Psychology Swansea University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Problematic internet use has been a growing concern for many people and bodies over the last decade, and more study has been requested into various aspects of this possible disorder.  One of the key questions is whether people overuse the internet, due to an addiction.  If it is an addiction, then there should be signs of withdrawal when people, who report having this problem, stop using the internet.  In this study, 144 participants, aged 18 to 33, had their heart rate and blood pressure measured before and after a brief internet session.  Their anxiety and self-reported internet addiction were also assessed. The results showed increases in heart rate and systolic blood pressure on terminating the internet session for those with problematically-high internet usage.  These increases in physiological arousal were mirrored by increased feelings of anxiety.  However, there were no such changes for those participants who reported no internet-usage problems.

Author Interviews, JAMA, Surgical Research / 12.06.2017

MedicalResearch.com Interview with: Virginia Sun, RN, PhD Assistant Professor Division of Nursing Research and Education Department of Population Sciences Cancer Control and Population Sciences Program City of Hope Duarte, CA 91010  MedicalResearch.com: What is the background for this study? Response: Surgery is one of the most effective and important treatment strategies for cancer. Surgical procedures are by definition invasive, and patients are at risk for unpleasant symptoms, impaired functional status, and poor quality of life. Traditionally, mortality has been the sole measure to assess the risk of most surgical procedures. However, as surgical mortality has sharply declined, focus has shifted toward other endpoints, including patient-centered outcomes. There are critical gaps to assessing and integrating patient-centered outcomes into the surgical oncology workflow. We conducted this proof-of-concept study to assess the feasibility and acceptability of a wireless monitoring approach for patient-centered outcomes before and after a major abdominal cancer surgery.

MedicalResearch.com Interview with: Katrina Donahue MD, MPH Professor, Director of Research, UNC Family Medicine. Co-Director, North Carolina Newtork Consortium (NCNC). Chapel Hill, NC MedicalResearch.com: What is the background for this study? Response: Type 2 diabetes is an epidemic affecting one in 11 people in the United States. For those treated with insulin, checking blood sugar with a finger stick at home is an accepted practice for monitoring the effects of insulin therapy. However, the majority of patients with type 2 diabetes are not treated with insulin. These patients, too, are often recommended glucose monitoring, despite an ongoing debate about its effectiveness in controlling diabetes or improving how patients feel. Currently, 75 percent of non-insulin treated type 2 diabetes patients perform regular blood glucose testing at home, generally at the recommendation of a provider. “The MONITOR Trial” is the first large pragmatic study examining glucose monitoring in the United States.

Author Interviews, Education, Psychological Science, Technology, University of Pennsylvania / 21.05.2017

MedicalResearch.com Interview with: Jason Han, MD Resident, Cardiothoracic Surgery Hospital at the University of Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: The inspiration for this study comes from my personal experience as a medical student on clinical rotations. Despite having been a victim of a medical error while growing up myself, I found it extraordinarily difficult to admit to even some of my smallest errors to my patients and team. Perplexed by the psychological barriers that impeded error disclosure, I began to discuss this subject with my advisory Dean and mentor, Dr. Neha Vapiwala. We wanted to analyze the topic more robustly through an academic lens and researched cognitive biases that must be overcome in order to facilitate effective disclosure of error, and began to think about potential ways to implement these strategies into the medical school curriculum with the help of the director of the Standardized Patient program at the Perelman School of Medicine, Denise LaMarra. We ultimately contend that any educational strategy that aims to truly address and improve error disclosure must target the cognitive roots of this paradigm. And at this point in time, simulation-based learning seems to be the most direct way to do so, but also remain hopeful that emerging technologies such as virtual and augmented reality may offer ways for students as well as staff to rehearse difficult patient encounters and improve.

Author Interviews, Education, Technology / 01.05.2017

MedicalResearch.com Interview with: Frederick W. Kron, MD President and Founder of Medical Cyberworlds, Inc Department of Family Medicine,Ann Arbor, MI and Michael D. Fetters, M.D., M.P.H., M.A. Professor of Family Medicine University of Michigan MedicalResearch.com: What is the background for this technology and study? Dr. Kron: Communication is the most important component of the doctor-patient relationship. I know that through research, but also through personal experience. As a cancer survivor, I’ve seen first-hand the difference that outstanding communication skill can make to a vulnerable patient. At the beginning of the project, we asked medical educators about the challenges they had in assessing and training communication competency. They told us that technical skills are easy to teach and assess, but communication skills are mainly behavioral skills that involve verbal and nonverbal behaviors, facial expressions, and many other cues that pass between patient and provider. That’s hard to teach and assess. Activities like role play with standardized patients (SPs) have been widely used, but it’s impossible for SPs to accurately portray these behaviors, or for faculty to fully assess the nuanced behaviors of both learner and patient. Supporting this idea is a lack of evidence proving that SP encounters translate in behavioral changes or transfer into clinical settings. Developments in virtual reality provided us with a great opportunity for assessing and teaching of communication behaviors. Working with a national group of experts, we created computer-based Virtual Humans that interact with learners using the full range of behaviors you’d expect from two people talking together. They are so behaviorally realistic and compelling, that they trigger emotional responses in learners, and make learners want to learn so they can do their best. Dr. Fetters: Our team has particular interest in doctor-patient communication in the context of cancer. There are many critical aspects of cancer communication: breaking the bad news to the patient, negotiating sometimes conflicting family opinions about treatment, and communication among team members about the patient's care, just to name a few. We’ve begun building out those scenarios in the technological platform we developed, Mpathic-VR. (more…)
Author Interviews, Dermatology, JAMA, Melanoma, Technology / 27.04.2017

MedicalResearch.com Interview with: Laura Korb Ferris, MD, PhD Associate Professor, University of Pittsburgh Clinical and Translational Science Institute Director of Clinical Trials Department of Dermatology University of Pittsburgh Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: We found that a non-invasive adhesive patch applied to the skin over a pigmented skin lesion allowed us to capture enough genetic material from the lesion to analyze and predict if that lesion is likely to be melanoma, meaning a biopsy is warranted, or if it is likely benign, meaning the patient would not need a skin biopsy. In this study, we asked dermatologists to use their clinical judgement to decide if they would recommend biopsying a skin lesion based on photos and information about the lesion and the patients, such as the patient's age, personal and family history of skin cancer, and if the lesion was new or changing. We then provided them the read out of the gene test and asked them how this influence their decision. We found that with this test result, dermatologists were more accurate in their decision making, meaning they were more likely to recommend biopsy of melanomas and less likely to biopsy harmless moles than they were without the test. This is important as it means this test has the potential to reduce the number of unnecessary skin biopsies performed, saving patients from undergoing a procedure and having a scar as a result, without increasing the risk of missing a melanoma.

MedicalResearch.com Interview with: Sang Jin Lee, Ph.D. Associate Professor of Wake Forest Institute for Regenerative Medicine Wake Forest School of Medicine Wake Forest University MedicalResearch.com: What is the background for this study? What are the main findings? Response: I received my Ph.D. in Chemical Engineering at Hanyang University, Seoul, South Korea in 2003 and took a postdoctoral fellowship in the Laboratories for Tissue Engineering and Cellular Therapeutics at Harvard Medical School and Children’s Hospital Boston and the Wake Forest Institute for Regenerative Medicine where I am currently a faculty member. My research works have focused on development of smart biomaterial systems that support the regenerative medicine strategies and approaches. These biomaterial systems combined with drug/protein delivery system, nano/micro-scaled topographical feature, or hybrid materials that could actively participate in functional tissue regeneration. Recently my research works utilize 3D bioprinting strategy to manufacture complex, multi-cellular living tissue constructs that mimic the structure of native tissues. This can be accomplished by optimizing the formulation of biomaterials to serve as the scaffolding for 3D bioprinting, and by providing the biological environment needed for the successful delivery of cells and biomaterials to discrete locations within the 3D structure.

MedicalResearch.com Interview with: Paul J.D. Whiteside, doctoral candidate and Dr. Heather Hunt, assistant professor of bioengineering University of Missouri MedicalResearch.com: What is the background for this technology? What are the barriers to the use of conventional laser treatment of tattoos? Response: Traditional laser treatments rely on the concept of selective photothermolysis (laser-induced heating) to specifically target certain structures for treatment, while leaving other parts of the skin unaffected. The problem with traditional laser treatments is that the laser needs to transmit through the epidermis, which acts as a barrier to laser transmission both due to its reflective properties and because it is filled with light-absorbing melanin, the pigment that gives our skin its color. Sonoillumination acts to change the properties of the epidermis temporarily using painless ultrasound technology, thereby allowing more laser light to penetrate deeper into the skin to impact desired targets, such as hair follicles, tattoos, and blood vessels. Funding for clinical trials is currently being sought to provide evidence for what we surmise may be benefits of this technology relative to traditional laser treatments. These benefits may include being able to treat darker-skinned people more effectively, being able to provide laser therapy with less risk of scarring or pigment changes, and being able to do treatments with less discomfort, fewer treatments, and lower laser energy settings.

MedicalResearch.com Interview with: Amrut V. Ambardekar, MD Medical Director Cardiac Transplant Program Division of Cardiology, Section of Advanced Heart Failure-Transplant Cardiology University of Colorado MedicalResearch.com: What is the background for this study? What are the main findings? Response: As left ventricular assist device (LVAD) technology has improved, the appropriate timing for implant of these devices (essential a form of an artificial heart pump) in patients with advanced heart failure is unknown. The goal of the MedaMACS study was to describe the prognosis of a group of patients with advanced heart failure who currently do not require intravenous therapies, and determine how they compare to a similar group of patients who received a LVAD. The main finding from this study is that the “sickest” group of patients with advanced heart failure on oral medical therapy (known as INTERMACS profile 4 patients) have very poor outcomes with a strong trend for improvement in survival with LVAD therapy. The other take home message is that among all of the patients enrolled in the study on medical therapy, only approximately half were alive after an average of 12 months of follow up without needing a heart transplant or LVAD placement.

MedicalResearch.com Interview with: Chandra Y. Osborn, PhD, MPH VP, Health & Behavioral Informatics One Drop Informed Data Systems, Inc. MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are over 1,500 mobile apps for people with diabetes, but minimal evidence on their benefit. The One Drop | Mobile app launched in April 2015. Users manually and automatically track their blood glucose and self-care activities via One Drop's | Chrome glucose meter, other Bluetooth-enabled meters, CGMs or other health apps. Users leverage One Drop’s food library, medication scheduler, automatic activity tracking, educational content, recipes, health tips, user polls, and peer support (‘likes’, stickers, and data sharing), and can set blood glucose, medication, carbohydrate intake, and activity goals, receive data-driven insights to draw connections between their behaviors, goals, and blood glucose readings. They can also self-report and track their hemoglobin A1c (A1c) and weight. In July 2016, we queried data on ~50,000 people using One Drop | Mobile. In March 2017, we queried data on >160,000 users. Only users who had entered an A1c value when they started using the app, and entered a second A1c at least 60 days apart, but no more than 365 days apart, were included. In July 2016, people with diabetes using One Drop | Mobile reported a nearly 0.7% reduction in A1c during 2-12 months of using One Drop. In March 2017, users reported a 1.0% reduction in A1c for the same timeframe. A more recent diabetes diagnosis and using One Drop to track self-care activities was associated with more A1c improvement. (more…)
Author Interviews, Cognitive Issues, Multiple Sclerosis, NYU / 01.03.2017

MedicalResearch.com Interview with: Leigh E. Charvet, PhD Associate Professor, Department of Neurology Department of Neurology New York University Langone Medical Center New York, NY MedicalResearch.com: What is the background for transcranial direct current stimulation? What are the main findings of this study in multiple sclerosis patients? Response: The application of tDCS is a relatively recent therapeutic development that utilizes low amplitude direct currents to induce changes in cortical excitability. When paired with a rehabilitation activity, it may improve learning rates and outcomes. Multiple repeated sessions are needed for both tDCS and cognitive training sessions to see a benefit. Because it is not feasible to have participants come to clinic daily for treatments, we developed a method to deliver tDCS paired with cognitive training (using computer-based training games) to patients at home. Our protocol uses a telemedicine platform with videoconferencing to assist study participants with all the procedures and to ensure safety and consistency across treatment sessions. When testing our methods, we enrolled 25 participants with multiple sclerosis (MS) completed 10 sessions of tDCS (2.0 mA x 20 minutes, dorsolateral prefrontal cortex, left anodal) using the remotely-supervised telerehabilitation protocol. This group was compared to n=20 MS participants who completed 10 sessions of cognitive training only (also through remote supervision). We administered cognitive testing measures at baseline and study end. We found that both the tDCS and cognitive training only group had similar and slight improvements on composites of standard neuropsychological measures and basic attention. However, the tDCS group had a significantly greater gain on computer-based measures of complex attention and on a measure of intra-individual variability in response times. (more…)
