Xuemei Sui, MD, MPH, PhD Assistant Professor, Department of Exercise Science Division of Health Aspects of Physical Activity Arnold School of Public Health University of South Carolina Columbia, SC 29208Xuemei Sui, MD, MPH, PhD Assistant Professor, Department of Exercise Science Division of Health Aspects of Physical Activity Arnold School of Public Health University of South Carolina Columbia, SC 29208 Medical Research: What are the main findings of the study? Dr. Sui: First, blood pressure is inversely associated with cardiorespiratory fitness levels among men. People in higher fitness categories had lower blood pressure than those in lower fitness categories. Second, fitness is a strong effect modifier for the systolic blood pressure aging trajectory. A higher fitness level can significantly delay the natural age-associated increase in blood pressure. (more…)
Author Interviews, Dermatology, JAMA, Metabolic Syndrome / 19.09.2014

MedicalResearch.com Interview : Iben Marie Miller, MD Department of Dermatology Roskilde Hospital, Roskilde Department of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark Medical Research: What are the main findings of the study? Dr. Miller: Using a cross-sectional design based on data from a Hidradenitis Suppurativa (HS) group recruited from the hospital (32 individuals), an HS group recruited from the general population (326 individuals) and 14,851 individuals without Hidradenitis Suppurativa, we investigated a possible association of Hidradenitis Suppurativa and the metabolic syndrome. We found that the HS groups had 2 to 4 times odds of having the metabolic syndrome when compared to individuals without HS leaving Hidradenitis Suppurativa patients at a high cardiovascular risk. Furthermore, we found that the odds were higher for the HS group from the hospital in comparison to the Hidradenitis Suppurativa group from the general population. (more…)

Dr. Jyotsna Batra QUT Institute of Health and Biomedical Innovation's  Queensland University of Technology Queensland, AustraliaMedicalResearch.com Interview with: Dr. Jyotsna Batra QUT Institute of Health and Biomedical Innovation's Queensland University of Technology Queensland, Australia   Medical Research: What are the main findings of the study? Dr Batra: Prostate cancer is a disease with upto 40% genetic component. Previous Genome-wide association studies have identified 77 risk loci associated with prostate cancer. This study is further extension of previous GWASs and also involved meta-analysis of multi-ethnic populations. Through this large study involving approximately 90,0000 individuals, 23 new susceptibility loci were identified to be associated with prostate cancer, 15 variants were identified among men of European ancestry, 7 were identified in multi-ancestry analyses and 1 was associated with early-onset prostate cancer.

Judith Trotman MBChB, FRACP, FRCPA Associate Professor Concord Hospital University of Sydney, AustraliaMedicalResearch.com Interview with: Judith Trotman MBChB, FRACP, FRCPA Associate Professor Concord Hospital University of Sydney, Australia Medical Research: What are the main findings of the study? Dr. Trotman: That PET-CT (applying the cut-off of ≥4 on the now internationally recommended 5 Point Scale) is a more powerful predictor of both Progression Free and Overall Survival than conventional CT in patients responding to first line immunochemotherapy for advanced follicular lymphoma.  It is also a much stronger predictor than the pre-treatment prognostic indices FLIPI and FLIP2. Patients who achieve PET-negative status have a median PFS over 6 years compared to only 17 months in those who remain PET-positive. (more…)

Rebecca Smith-Bindman, MD Professor in the Departments of Radiology; Epidemiology and Biostatistics; and Obstetrics, Gynecology and Reproductive Medicine UCSF San Francisco Calif.MedicalResearch.com Interview with: Rebecca Smith-Bindman, MD Professor in the Departments of Radiology; Epidemiology and Biostatistics; and Obstetrics, Gynecology and Reproductive Medicine UCSF San Francisco Calif. Medical Research: What are the main findings of the study? Dr. Smith-Bindman: New technology is rapidly developed in medicine, and its important to understand how that technology should be used to improve patient health outcomes. Sometimes the technology is far better than existing technology and it should replace the earlier technology, and sometimes it is not and therefore should not be used. In this clinical scenario – I e. patients who present to an emergency department with abdomen or back pain thought to possibly reflect kidney stones, ultrasound is a simpler, less expensive , and more readily available test in the emergency department setting and therefore if it is equal to CT with respect to patient outcomes, it should be used as the first test in these patients. Currently, CT is the test widely used for patients with suspected kidney stones. We assessed a large number of patients with suspected kidney stones seen at one of 15 large academic emergency medicine departments across the country. Patients were assigned to point of care ultrasound performed by an ED physician, radiology ultrasound or radiology CT. We assessed a broad range of patient centered outcomes and found each of the three tests we studied were equivalent in terms of these outcomes including complications related to missed diagnoses, related serious adverse events, time spent in the emergency department and repeated ED visits and hospitalizations. However, the exposure to ionizing radiation was around half as high in patients who underwent ultrasound as their first test, and thus ultrasound should be used as the first imaging test in patients with suspected nephrolithiasis.

Addiction, Author Interviews, JAMA, PTSD / 17.09.2014

Susan Mason, PhD, MPH Assistant Professor Division of Epidemiology and Community Health Minneapolis, MN  55454MedicalResearch.com Interview with: Susan Mason, PhD, MPH Assistant Professor Division of Epidemiology and Community Health Minneapolis, MN  55454   Medical Research: What are the main findings of the study? Dr. Mason: We examined 49,408 women enrolled in the Nurses' Health Study II to see if those who had experienced PTSD symptoms at some point in their lives were more likely than those without PTSD symptoms to meet the criteria for food addiction, a measure of perceived dependence on food. We found that the 8% of women with the most lifetime PTSD symptoms were about 2.7 times as likely to meet the criteria for food addiction as women with no lifetime PTSD symptoms. This translates to an elevation in food addiction prevalence from about 6% among women with no PTSD symptoms to about 16% in women with the most PTSD symptoms. (more…)

Darren J. Malinoski, MD, FACS Assistant Chief of Surgery – Research and Education Chief, Section of Surgical Critical Care Portland VA Medical Center Associate Professor of Surgery Oregon Health & Science University Portland, OR 97207MedicalResearch.com Interview with: Darren J. Malinoski, MD, FACS Assistant Chief of Surgery – Research and Education Chief, Section of Surgical Critical Care Portland VA Medical Center Associate Professor of Surgery Oregon Health & Science University Portland, OR 97207 Medical Research: What are the main findings of the study?  Dr. Malinoski: Our two main findings are that the status of the DMG Bundle prior to organ recovery, at the end of the OPO donor management process, is the most predictive of the number of organs that will be transplanted per expanded criteria donor (ECD) and that the absolute increase in the number of individual DMG elements achieved over time also appears to be relevant.  Taken together, these two findings suggest that the number of organs that will be transplantable from each donor is not necessarily predetermined by their age, comorbidities, and pre-neurologic death condition, but that active critical care management has the ability to affect outcomes and reassessing each donor’s condition over time is necessary.

Dr Neha Pathak, MBBS MA(Cantab) Academic Clinical Fellow in Obstetrics and Gynaecology Queen Mary University London.MedicalResearch.com Interview with: Dr Neha Pathak, MBBS MA(Cantab) Academic Clinical Fellow in Obstetrics and Gynaecology Queen Mary University London. Medical Research: What are the main findings of the study? Dr. Pathak: Cervical testing for human papillomavirus (HPV) is being piloted as a more accurate method for cervical cancer screening than current cytology-based ("Pap smears"). However, cervical testing still requires gynaecological examination and a doctor or nurse to take the sample. This could be a deterrent to attending screening as it is invasive and time-consuming. Urine-based HPV testing would be a less invasive and more convenient alternative. Our study was completed at the Queen Mary University London Women's Health Research Unit. We pooled the results of 14 studies from around the world which tested 1443 women for HPV in urine and cervical samples. We found that detection of HPV in urine seems to have good accuracy for the detection of HPV present in the cervix. We also found that using first void samples (the first part of the stream of urine) was twenty-two times more accurate than random or midstream urine samples. (more…)

MedicalResearch.com Interview with: Dr. Adam Tabak MD Clinical Research Associate Epidemiology & Public Health Institute of Epidemiology & Health Faculty of Population Health Sciences University College London, UK Medical Research: What are the main findings of the study?   Dr. Tabak: Some of the major findings are confirmatory, such as the almost 3 times increased risk and an earlier onset of type 2 diabetes among south Asians, and a decreased insulin sensitivity in this ethnic group. The major novel finding is related to the fact that we could model events before diabetes diagnosis. We found a faster increase in fasting glucose before the diagnosis is south Asians compared to whites and that although insulin secretion increased in both ethnicities until 7 years before diagnosis, this increase was faster among whites.

Author Interviews, Breast Cancer / 17.09.2014

Blake Cady MD Professor Emeritus of Surgery Brown UniversityMedicalResearch.com Interview with: Blake Cady MD Professor of Surgery (emeritus) at Harvard Medical School Partners HealthCare, Harvard Medical School institutions, Boston Medical Research: What are the main findings of this study? Dr. Cady:  Our findings support mammography screening, and our data is consistent with the randomized trials. Breast cancer screening with mammography is the most extensively researched screening method ever studied. Only one  “randomized" trial failed to show reduced mortality, (Canadian NCSS studies),  and there were major flaws in its design and execution that negate their results, as noted in multiple critical publications (volunteers, not geographic assignment, palpable masses detected at examination assigned to “screening” arm, large contamination bias (control group got screened anyway), and very poor quality of mammography). Yet it is this NCSS study that is cited by critics and the press.  “Failure Analyses” look backward from death, rather than forward from assignment in randomized trials. The concept of failure studies is well established as noted in recent reports of air-bag failures in cars, and many industrial studies. Seat belt prevention of deaths was discovered by police recording injuries and deaths in crashes after the fact - a failure analysis - not by randomized clinical trials. In breast cancer, failure analyses have advantages of little cost, early results, simplicity, and convenience, compared to randomized trials. Since our results support findings from randomized clinical trials (RCT), they can be accepted as reliable and accurate. Our findings show that about 71% of deaths from breast cancer occur in the  approximately 20% of our patients not in regular screening programs, while only 29% of deaths occur in the 80% of women who were regularly screened by mammography. By extrapolation, women regularly screened have only about a 5% breast cancer mortality, but women not screened have close to a 50% mortality. (This is my extrapolation from our data, not direct data from our “Failure Analysis”) (more…)

Aner Tal, PhD Food and Brand Lab Department of Applied Economics and Management Cornell University, Ithaca, New YorkMedicalResearch.com Interview with: Aner Tal, PhD Food and Brand Lab Department of Applied Economics and Management Cornell University, Ithaca, New York Medical Research: What are the main findings of the study? Dr. Tal: Some TV programs might lead people to eat twice as much as other programs. “We find that if you’re watching an action movie while snacking your mouth will see more action too!” says Aner Tal, Ph.D. lead author on the new article just published in the Journal of the American Medical Association: Internal Medicine. “In other words, the more distracting the program is the more you will eat.” In the study 94 undergraduates snacked on M&Ms, cookies, carrots and grapes while watching 20 minutes of television programming. A third of the participants watched a segment of the action movie The Island, a third watched a segment from the talk show, the Charlie Rose Show, and a third watched the same segment from The Island without sound. “People who were watching The Island ate almost twice as many snacks – 98% more than those watching the talk show!” says co-author Brian Wansink, author of Slim by Design (forthcoming) and Professor and Director of the Cornell Food and Brand Lab. “Even those watching “The Island” without sound ate 36% more.” People watching the more distracting content also consumed more calories, with 354 calories consumed by those watching The Island (314 calories with no sound) compared to 215 calories consumed by those watching the Charlie Rose Show. “More stimulating programs that are fast paced, include many camera cuts, really draw you in and distract you from what you are eating. They can make you eat more because you're paying less attention to how much you are putting in your mouth,” explains Tal. Because of this, programs that engage viewers more might wind up being worse for their diets. (more…)

Professor Aubrey Sheiham Emeritus Professor of Dental Public Health Department of Epidemiology & Public Health, University College London, WC1E 6BT. UK.MedicalResearch.com Interview with: Professor Aubrey Sheiham Emeritus Professor of Dental Public Health Department of Epidemiology & Public Health, University College London, WC1E 6BT. UK. Medical Research: What are the main findings of the study? Prof Sheiham: There is a robust log-linear relationship of caries to sugar intakes from zero to 10% of sugars as a proportion of total energy intake. Furthermore our analyses showed that sugar intakes of 10%E sugars intake that is currently recommended as an upper limit for free sugars by the WHO and the Scientific Advisory Committee on Nutrition in England would induce a very costly burden of caries in most populations. Second, we found that free sugars* in the diet should make up no more than 3% of total energy intake. Above that level they cause a significant level of tooth decay across the lifecourse of most people in the developed world. Third, we were able to show that despite widescale fluoride use from both toothpastes and drinking water the mean numbers of decayed, missing and filled teeth (DMFT) and decayed and filled surfaces (DFS) for adults increased with sugar use despite the presence of fluoride. *Free sugars are defined by the World Health Organisation Nutrition Guidance Adivisory Group as follows: “Free sugars include monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit concentrates.” (more…)

MedicalResearch.com Interview with: Alison M Gallagher PhD FHEA RNutr (Public Health) Senior Lecturer in Human Nutrition Northern Ireland Centre for Food and Health (NICHE) School of Biomedical Sciences University of Ulster Northern Ireland, UK Medical Research: What are the main findings of the study? Dr. Gallagher: The main findings of the study were that overweight and obese males appeared to be more aware of food related images as compared to their normal weight counterparts.  Individuals, regardless of weight status also appeared to be more visually ‘tuned in’ to high energy dense food-related visual stimuli as compared to low energy dense food-related stimuli.  As high energy dense foods are overtly represented within the visual environment through food advertising, it may be of particular concern if certain individuals, in particular those who are overweight/obese, are demonstrating increased attention (an attentional bias) towards high energy dense food stimuli.

Marc Nieuwenhuijse MD Research fellow ICOR and FDA Weill Cornell Medical College New York CityMedicalResearch.com Interview with: Marc Nieuwenhuijse MD Research fellow ICOR and FDA Weill Cornell Medical College New York City   Medical Research: Why did you decide to study this topic? Dr. Nieuwenhuijse : The introduction of new orthopaedic implants and related technologies has been the focus of major scientific and policy discussions since the failures of articular surface replacement and large head size metal-on-metal articulations in total hip replacement were brought to light. However, scientists and policy makers seem to “run out of steam,” and the momentum for change generated by these recent high profile failures is waning. The consequences of uncontrolled device introduction worldwide may not be fully recognised by the scientific community and there is a high likelihood that current practice regarding device innovations will not change much. As such, there is a need to investigate whether the problems associated with the articular surface replacement and large head size metal-on-metal articulation are isolated events or if there is a systemic problem affecting the introduction of a much wider range of implantable devices. In this study, we systematically evaluate the evidence concerning the introduction of five substantial, innovative, relatively recent, and already widely implemented device technologies used in major total joint replacement to determine the evidence of effectiveness and safety for introduction of five recent and ostensibly high value implantable devices in major joint replacement to illustrate the need for change and inform guidance on evidence based introduction of new implants into healthcare.

Ankur Pandya, PhD Assistant Professor of Healthcare Policy and Research Departments of Healthcare Policy and Research Weill Cornell Medical College New York, NY 10065.MedicalResearch.com Interview with: Ankur Pandya, PhD Assistant Professor of Healthcare Policy and Research Departments of Healthcare Policy and Research Weill Cornell Medical College New York, NY 10065. Medical Research: What are the main findings of the study? Dr. Pandya: Asymptomatic carotid stenosis is a highly prevalent condition that can lead to ischemic stroke, which is a leading cause of death and healthcare costs in the U.S. Revascularization procedures are often performed on asymptomatic carotid stenosis patients, but experts have questioned whether the stroke prevention benefits outweigh the risks and costs of revascularization in these patients. Imaging-based stroke risk assessment has traditionally focused on the degree of artery narrowing, but there has been growing interest in using cerebrovascular reserve (CVR) assessment to stratify these patients into those that are more likely to have a stroke, and thus better candidates for revascularization, and those that would be better off with less invasive management strategies (such as medical therapy). We therefore developed a simulation model to evaluate whether the CVR-based decision rule could be used efficiently select the right patients for revascularization. We found that the CVR-based strategy represented the best value for money compared to immediate revascularizations or medical therapy-based treatment for all patients. (more…)

Dr. Carrier: Venous thromboembolism (VTE), comprised of deep vein thrombosis and pulmonary embolism, is the third leading cause of cardiovascular death. There are many anticoagulant treatments available but there is little guidance about which treatment is most effective and safe. This systematic review and network meta-analysis evaluated eight different treatment options for acute Venous thromboembolism.  Forty-five trials were included in the analysis and there were no significant differences in clinical or safety outcomes associated with most treatment options when compared to the combination of LMWH-VKA..

Lex W Doyle MD BS MSc FRACP Professor of Neonatal Paediatrics Department of Obstetrics and Gynaecology The Royal Women’s Hospital Parkville, Victoria, AustraliaMedicalResearch.com Interview with: Lex W Doyle MD BS MSc FRACP Professor of Neonatal Paediatrics Department of Obstetrics and Gynaecology The Royal Women’s Hospital Parkville, Victoria, Australia Medical Research: What are the main findings of the study? Dr. Doyle: From collectively pooling data from five large trials carried out around the world over the past 20 years, we know that magnesium sulfate given under strict medical protocols in hospital to women threatening to deliver preterm reduces the risk of cerebral  palsy in their children in early childhood.  Following  from this knowledge, magnesium sulfate is now given routinely to women, under strict medical conditions, who are threatening to deliver very early in Australia, and in other parts of the world, to try to prevent cerebral palsy in their child.  What we do not know is if magnesium sulfate used this way has any longer-term effects on the brain or on other important outcomes. One of the initial studies that contributed to the overall evidence about cerebral palsy was carried out in Australia and New Zealand and completed more than 10 years ago.  Over 1000 women and their babies were enrolled in that study and although the rate of cerebral palsy was not substantially reduced by magnesium sulfate in our study, we showed that there were fewer children at 2 years of age who were not walking in the group whose mothers were given magnesium compared with those whose mothers were given placebo.  With this knowledge, and given the unknown longer-term benefits or risks, we re-evaluated the children from our study at school-age, between 6-11 years of age.  We thoroughly evaluated their brain function, including movement and co-ordination, thinking ability, behaviour, and school progress, as well as general health and well-being.  The basic message from our longer-term study is that magnesium sulfate, as used in our trial, does not have any substantial benefits or harms on brain or cognitive function, or any other outcome at school age.

Dr. Koton: Based on data on 14,357 participants in the Atherosclerosis Risk in Communities (ARIC) study who were free of stroke when the study began in 1987 and followed until the end of 2011, we found a 24 percent overall decline in first-time strokes in each of the last two decades and a 20 percent overall drop per decade in deaths after stroke. The results were similar across race and gender, but varied by age: the decline in stroke risk was concentrated mainly in the over-65 set, while the decrease in stroke-related deaths was primarily found among those under age 65.

Muthiah Vaduganathan, MD MPH Department of Medicine Massachusetts General Hospital Boston, MassMedicalResearch.com Interview with: Muthiah Vaduganathan, MD MPH Department of Medicine Massachusetts General Hospital Boston, Mass Medical Research: What are the main findings of the study? Dr. Vaduganathan: Based on data from a large, multinational randomized controlled trial of patients hospitalized for heart failure and reduced ejection fraction (HFrEF), we conducted a retrospective analyses of the clinical profiles associated with baseline serum uric acid levels. Serum uric acid was commonly elevated in patients hospitalized for heart failure and reduced ejection fraction (mean ~9 mg/dL), especially in men and black patients. Higher uric acid levels were associated with lower systolic blood pressure and EF, higher natriuretic peptides, and more impaired renal function. After accounting for 24 known baseline covariates, serum uric acid was independently predictive of post-discharge mortality and rehospitalization in patients with relatively preserved renal function, but not in those with poor renal function.

Dr. Li: Using the 2001 to 2009 National Program of Cancer Registries (NPCR) and Surveillance, Epidemiology, and End Results (SEER) data, which represent 94.2% of the US population, we identified 120,137 pediatric cancer cases with an incidence rate of 171 cases per million children and adolescents. Overall cancer incidence rates were stable from 2001-2009. However, we found rates were increasing significantly at 1.3% per year in African American children and adolescents.  This increase might be partially attributed to the rise among renal tumors and thyroid cancer. We also found rising incidence in thyroid cancer and renal carcinoma among children and adolescents. As has been previously established, pediatric cancer is more common in males, in white, in adolescents, and in the Northeast. Leukemia is the most common pediatric cancer, followed by central nervous system (CNS) neoplasms, and then lymphomas. (more…)

Gert Bronfort, DC, PhD Professor, Integrative Health and Wellbeing Research Program Center for Spirituality & Healing University of MinnesotaMedicalResearch.com Interview with: Gert Bronfort, DC, PhD Professor, Integrative Health and Wellbeing Research Program Center for Spirituality & Healing University of Minnesota Medical Research: What are the main findings of the study? Were any of the findings unexpected? Dr. Bronfort: Our study found that spinal manipulative therapy  SMT coupled with home exercise and advice (HEA) appears to be helpful compared to home exercise and advice alone (especially in the short term) for patients with sub-acute and chronic back-related leg pain (BRLP). BRLP was defined as radiating pain originating from the lumbar spine, which travels into the proximal or distal lower extremity, with or without neurological signs. Patients with progressive neurological deficits, cauda equina syndrome, spinal fracture, and other potentially serious causes of BRLP (and often candidates for surgery) were EXCLUDED. There were a few things we did find to be quite interesting. First, it is notable that the spinal manipulative therapy & home exercise and advice group experienced less self-reported medication use after one year than the  home exercise and advice alone group (SMT&HEA was 2.6 times more likely to experience fewer medication days than HEA alone at 1 year). Given the growing concerns of overuse of pain medications (and the potential for adverse events and addiction), this is a finding that has important public health consequence. Another interesting and important finding is that the adverse events observed in this study were only mild to moderate and self-limiting. No serious adverse events occurred that were related to the study interventions. Mild to moderate adverse events (e.g. temporary aggravation of pain, muscle soreness, etc.) were reported by 30% of the patients in the SMT&HEA group, and 42% in the HEA group. This is important as few studies have systematically recorded the side effects and adverse events related to SMT&HEA and HEA alone; this is one of the first, larger clinical trials to do so. These findings are especially notable because SMT is often not recommended for patients with leg symptoms because of safety concerns (which might be related to the previous absence of robust scientific data to support its use). Finally, while an advantage of SMT& HEA versus HEA was found (especially in the short term), we do find the findings of the HEA alone group to also be of interest. Almost half of the HEA patients experienced a 50% reduction in leg pain symptoms in both the short (at 12 weeks) and long term (at 52 weeks). That’s an important improvement and warrants future investigation. Self-management strategies (like home exercise) that emphasize the importance of movement and fitness, restoration of normal activities, and allow patients to care for themselves embrace important principles for promoting overall health and wellbeing that could have a big impact if routinely put into practice.

Nienke de Glas, MD PhD-student Leiden University Medical Center Department of Surgery Leiden The NetherlandsMedicalResearch.com Interview with: Nienke de Glas, MD PhD-student Leiden University Medical Center Department of Surgery Leiden The Netherlands Medical Research: What are the main findings of the study? Dr. de Glas: It remains unclear whether mass breast cancer screening has a beneficial effect in older women. In the Netherlands, the upper age limit of the breast cancer screening program was extended from 69 to 75 years in 1998. If a screening program is effective, it can be expected that the incidence of early stage tumours increases, while the incidence of advanced stage tumours decreases. The aim of this study was to assess the incidence of early stage and advanced stage breast cancer before and after the implementation of mass screening in women aged 70-75 years in the Netherlands. We showed that the extension of the upper age limit to 75 years has only led to a small decrease of advanced stage breast cancer, while the incidence of early stage tumours has strongly increased. For every advanced stage tumour that was prevented, 20 “extra” and early stage tumours were diagnosed. (more…)

Rashid Bashshur, PhD Senior Advisor for eHealth Professor Emeritus, Department of Health Management and Policy Executive Director, UMHS eHealth Center University of Michigan Health SystemMedicalResearch.com Interview with:  Rashid Bashshur, PhD Senior Advisor for eHealth Professor Emeritus, Department of Health Management and Policy Executive Director, UMHS eHealth Center University of Michigan Health System Medical Research: What are the Main findings of the study? Dr. Bashshur: The main findings can be summarized as follows:
  •  The prevalence of chronic disease is increasing due to the changing demographic composition of the population and unhealthy life styles. Chronic diseases are expensive, accounting for about 70% of health care expenditures;  but  they are amenable to telemedicine interventions.  These interventions consist of ongoing monitoring of patients living in their own home environments, engaging them in managing their health,  providing them with educational materials and the necessary tools to manage their life style mostly by avoiding risky behaviors and adopting healthy ones.
  • Telemedicine interventions consist of various configurations of technology (telephone, video, wired or wireless, automated or manual) , human resources (physicians, nurses, combinations, and patient populations at various levels risk levels or severity of illness, The interventions investigated to date also vary in terms of study design, duration of application (during the study period), and frequency of administration of the intervention.  Hence, the findings must be viewed from the perspective of the specific methodological attributes  of the studies that were performed.
  • Using only robust studies from 2000 to the near present, and limited to congestive heart failure, stroke and COPD.  With notable exceptions,  overall there is substantial and fairly consistent evidence of:
  • A decrease in use of service, including hospitalization, rehospitalization, and emergency depart visits as a result of the telemedicine intervention.
  • Improved health outcomes.
  • Improved event timing for stroke patients.
  • Reduced exacerbations of symptoms for COPD patients
  • Some interesting  trends  to be considered:
  • Frail and elderly patients, those with co-morbid conditions, and those in advanced stages of illness are not likely to benefit from telemedicine interventions, as compared to their counterparts.
  • Visual information as in videoconferencing proved superior to telephone only connection for the diagnosis and treatment of stroke patients.
  • There could be a tradeoff between extra nursing time versus reduced physician time in some settings, but the net effect is cost savings.
  • There seems to be a paradoxical telemedicine effect in terms of increasing longevity but no reduction in hospitalization, reported in few studies.

MedicalResearch.com Interview with: MichDr. Michael Super, Ph.D.ael Super M.Sc., PhD Senior Staff Scientist Advanced Technology Team Wyss Institute at Harvard Center for Life Science, 2nd Floor Boston MA 02115 Medical Research: What is the background for this study? How big a problem is sepsis? Dr. Super:
  • Sepsis is a major problem and is the primary cause of death from infection. The incidence of sepsis is rising.
  • Sepsis affects more than 18 M people each year and at least 1/3 ( 6 million) die every year of sepsis.
  • Sepsis is a disease that affects the very young and old and it is estimated that 60-80% of childhood deaths in the developing world are due to sepsis.

Anthony P. Kontos, Ph.D. Assistant Research Director UPMC Sports Medicine Concussion Program Associate Professor Department of Orthopaedic Surgery University of PittsburghMedicalResearch.com Interview with: Anthony P. Kontos, Ph.D. Assistant Research Director UPMC Sports Medicine Concussion Program Associate Professor Department of Orthopaedic Surgery University of Pittsburgh Medical Research: What are the main findings of the study? Dr. Kontos: Our new Vestibular/Ocular Motor Screening (VOMS) examination was able to accurately identify nearly 90% of patients with a concussion. In our study of 64 concussed patients approximately five days post-injury and 78 healthy control-group patients who were administered VOMS by trained clinicians, we also found that more than 60% of patients with a concussion reported symptoms or had impairment on the VOMS following their injury. The VOMS, which was developed in conjunction with an interdisciplinary team of experts, assesses five areas of the vestibular ocular system: smooth pursuits, saccades (rapid eye movement), horizontal vestibular ocular reflex (VOR), visual motion sensitivity (VMS), and near-point-of-convergence (NPC) distance.
