Author Interviews, JAMA, Johns Hopkins, Mammograms / 18.04.2017

MedicalResearch.com Interview with: Archana Radhakrishnan MD MHS Division of General Internal Medicine Johns Hopkins University Baltimore, Maryland MedicalResearch.com: What is the background for this study? What are the main findings? Response: We were interested in understanding the current practice trends in breast cancer screening recommendations by doctors in light of the guideline changes.  We performed a national survey of primary care providers and gynecologists asking about their breast cancer screening practices. We found that a large number of doctors recommend breast cancer screening to younger and older women—upwards of 80% of doctors recommend it for younger women (ages 40-44) and almost 70% for women 75 and older.  But this varies by the type of doctor that a woman see.  Gynecologists were, in general, more likely to recommend routine mammograms.

MedicalResearch.com Interview with: Dr. Hector Zenil Co-director Information Dynamics Lab Unit of Computational Medicine, SciLifeLab Center for Molecular Medicine Karolinska Institute, Stockholm, Sweden  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The generation of randomness is known to be related to cognitive abilities. It has also recently been shown that animals can recur to random behaviour to outsmart other animals or overcome certain situations. Our results that humans can best outsmart computers in generating randomness at a certain age (25). The results correspond to what it was suspected, that cognitive abilities peak at an early age before declining and that no other factor was important. We quantified a type of mathematical randomness that is known to be the true type of randomness as opposed to e.g. 'statistical randomness'. Something that is random is difficult to describe in a succinct way. Unlike 'statistical randomness', 'algorithmic randomness' does not only produce something that appears random but also that is very difficult to generate or produce. Conversely, something that may look random for the standard of statistical randomness may not turn out to be truly random.
Author Interviews, Heart Disease, HIV, JAMA, Vanderbilt / 18.04.2017

MedicalResearch.com Interview with: Matthew S Freiberg, MD, MSc Associate Professor of Medicine, Division of Cardiovascular Medicine Vanderbilt Translational and Clinical Cardiovascular Research Center MedicalResearch.com: What is the background for this study? Response:  HIV infected people are living longer and are at risk for cardiovascular diseases. While acute myocardial infarction has been studied and the increased risk of Acute Myocardial Infarction (AMI) among HIV+ people compared to uninfected people is well documented, there are less data describing the risk of HIV and different types of heart failure, including reduced and preserved ejection fraction heart failure. Understanding more about the link between HIV and different types of HF is important because reduced and preserved ejection fraction heart failure differ with respect to underlying mechanism, treatment, and prognosis. Moreover, as cardiovascular care has improved, HIV infected people who experience an AMI are likely to survive but may live with a damaged heart. Understanding more about the link between HIV and heart failure may help providers and their patients prevent or reduce the impact of HF on the HIV community.

MedicalResearch.com Interview with: Dr. Rebecca Rewbury Sussex Eye Hospital Brighton and Sussex University Hospitals Trust Brighton, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: ‘Poppers’ are recreational drugs which are illegal to sell for human ingestion, but are sold under the guise of household cleaning products. Inhalation leads to a brief sense of euphoria, enhanced sexual arousal and smooth muscle relaxation. The Psychoactive Substances Act 2016 was due to outlaw poppers, but they were excluded on the basis that they do not act directly on the central nervous system. The main constituent of poppers, isopropyl nitrite, replaced isobutyl nitrite when the latter was classified as a carcinogen in 2006. Since then, there have been several case reports of ‘poppers maculopathy.’ We noted an increase in patients presenting with central visual disturbances after using poppers and describe 12 such cases. They all demonstrated similar disruption of the photoreceptor layer on retinal imaging. Onset of symptoms was frequently linked to specific brands of poppers, with 3 people having used poppers for many years and only developing side effects on changing brand. Chemical analysis showed that these products contained isopropyl nitrite. One brand of poppers, used without side effects by one patient, contained amyl nitrite, 2-methyl butyl nitrite and isobutyl alcohol, but no isopropyl nitrite. The outcome of poppers maculopathy varied, but following abstention, visual disturbances and retinal damage tended to improve over months, if not fully resolve. Although in some cases, symptoms and/or imaging findings were prolonged. Ongoing use of implicated brands led to persistent, but not worsening maculopathy, whereas one patient that switched back to another brand showed full recovery.

MedicalResearch.com Interview with: Florence Gressier MD PhD Insermk Department of psychiatry CHU de Bicêtrem Le Kremlin Bicêtre France MedicalResearch.com: What is the background for this study? What are the main findings? Response: Results from recent studies have suggested an increased risk for Autism Spectrum Disorders (ASDs) in children exposed to antidepressants in utero. We performed a systematic review of and a meta-analysis of published studies to assess the association between ASDs and fetal exposure to antidepressants during pregnancy for each trimester of pregnancy and preconception. Our systematic review and meta-analysis suggests a significant association between increased ASD risk and maternal use of antidepressants during pregnancy; however, it appears to be more consistent during the preconception period than during each trimester. In addition, the association was weaker when controlled for past maternal mental illness. Maternal psychiatric disorders in treatment before pregnancy rather than antenatal exposure to antidepressants could have a major role in the risk for Autism Spectrum Disorders.

MedicalResearch.com Interview with: [caption id="attachment_33947" align="alignleft" width="160"]Zhiyong Zhao, Ph.D. Associate Professor Department of Obstetrics, Gynecology & Reproductive Sciences University of Maryland School of Medicine Baltimore, MD Dr. Zhiyong Zhao[/caption] Zhiyong Zhao, Ph.D. Associate Professor Department of Obstetrics, Gynecology & Reproductive Sciences University of Maryland School of Medicine Baltimore, MD MedicalResearch.com: What is the background for this study? What are the main findings? Response: Diabetes in early pregnancy can cause neural tube defects in fetus. The defects are a result of failure in neural tube closure, due to excess cell death. The aim of this study was to delineate molecular processes that induce cell death. The main findings of this study are: (1) Hyperglycemia disrupts protein folding. The misfolded proteins, including the ones that are associated with neurodegenerative diseases, form aggregates, indicating similar molecular processes in both fetal neural tube defects and adult neurodegenerative diseases. (2) Protein aggregation leads to formation of a neurodegenerative disease-related cell death inducting mechanism.

MedicalResearch.com Interview with: Joshua Barocas, MD Clinical and Research Fellow Division of Infectious Diseases Massachusetts General Hospital and Brigham and Women's Hospital  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Boston Health Care for the Homeless Program began treating HCV-infected individuals with the new oral medications. Based on clinical experience and previous experience with medication adherence in the setting of HIV, there were no clinical reasons that homeless persons should be excluded. As a result, we began to track the experience of treated individuals including cure, side effects, and adherence. We found that in the initial group of treated individuals, 62 of 64 persons achieved SVR. There were minimal side effects and adherence was excellent.

Dr. Jikui Song[/caption] Dr. Jikui Song PhD Assistant professor of biochemistry University of California, Riverside. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent outbreak of Zika virus (ZIKV) has become a wordwide health concern. However, no vaccines or antiviral drugs against ZIKV are currently available. To explore potential druggable sites for ZIKV, we set out to determine the crystal structure of full-length ZIKV NS5, the molecular machinery responsible for the genomic replication of ZIKV. The major findings of our study include the identification of a conserved domain conformation within flavivirus NS5 family, which may be important for functional regulation of flavivirus NS5. Furthermore, our structural analysis revealed a potential drug-binding site of ZIKV NS5, providing basis for future development of novel antivirals against ZIKV.

MedicalResearch.com Interview with: [caption id="attachment_33673" align="alignleft" width="170"]Marco A Zarbin, MD, PhD, FACS Alfonse Cinotti, MD/Lions Eye Research Professor and Chair Institute of Ophthalmology & Visual Science Rutgers-New Jersey Medical School Rutgers University Newark, NJ 0710 Dr. Zarbin[/caption] Marco A Zarbin, MD, PhD, FACS Alfonse Cinotti, MD/Lions Eye Research Professor and Chair Institute of Ophthalmology & Visual Science Rutgers-New Jersey Medical School Rutgers University Newark, NJ 0710  MedicalResearch.com: What is the background for this study? What are the main findings?
  1. Most large, randomized clinical trials are powered to assess the efficacy of drugs or interventions, but they usually do not enroll enough patients to accurately assess the frequency of uncommon, undesirable side effects.
  2. In order to compensate for this deficiency in trial design, investigators aggregate the results of numerous studies all of which address the same clinical question with the same (or similar) drugs/interventions to increase the power to detect uncommon side effects. These aggregate studies can be meta-analyses.
  3. Unfortunately, most meta-analyses do not have the ability to answer some critical questions such as the timing of an adverse event relative to the last exposure to the drug, nor can they compensate fully for differences among the aggregated studies in trial design, length of patient follow-up, or presence pre-existing risk factors for the side effects in question.
  4. A pooled analysis of combined clinical trials using patient level data, however, allows a more in depth analysis of side effects than study level data, which are usually used for most published meta-analyses, because patient level data allow one to incorporate the per-patient duration of exposure to treatment, adjust for imbalances in predefined baseline risk factors, and adjust for the effect of results of single studies on the overall result.

MedicalResearch.com Interview with: Robert Scragg, MBBS, PhD School of Population Health The University of Auckland Auckland New Zealand MedicalResearch.com: What is the background for this study? What are the main findings? Response: Interest in a possible role for vitamin D deficiency as a risk factor for cardiovascular disease was stimulated by studies showing a seasonal variation in cardiovascular disease, which is much higher in winter, when body levels of vitamin D are low, than in summer. Main findings are that bolus monthly doses of vitamin D supplementation do not prevent against cardiovascular disease, even in people with low levels of vitamin D.

MedicalResearch.com Interview with: Dr. Muhammad Ayub MBBS, MRCPsych, MSc., MD Professor of Psychiatry Chair Division of Developmental Disabilities Department of Psychiatry Queens University Kingston Kingston ON Canada MedicalResearch.com: What is the background for this study?  Response: Intellectual Disability affects about 1 percent of the population worldwide. Genetics play a major role in its etiology. Better understanding of the genetic causes is a necessary step in development of improved diagnosis and treatment. Recessive inheritance where the affected child inherits a defective copy of a gene from both the parents is an important genetic mechanism for prevalence of the disease in populations where within family marriages are common. These types of marital bonds are common in South Asia and Middle Eastern countries. The families where parents are related are an effective resource to study recessive forms of Intellectual Disability.

MedicalResearch.com Interview with: [caption id="attachment_33853" align="alignleft" width="163"]Lukas Landegger MD Molecular Neurotology Laboratory (PI Konstantina Stankovic) Massachusetts Eye and Ear Infirmary Dr. Landegger[/caption] Lukas Landegger MD Molecular Neurotology Laboratory (PI Konstantina Stankovic) Massachusetts Eye and Ear Infirmary MedicalResearch.com: What is the background for this study? What are the main findings? Response: Genetic hearing loss affects more than 125 million people worldwide and constitutes a major hurdle for language acquisition and child development in general. Technological advances over the last decades, such as cochlear implants, have made it possible for deaf children to partially regain their sense of hearing. However, these devices still have several shortcomings, especially when listeners attempt to understand speech in noise or listen to music. In establishing Anc80L65 as a reliable vector for gene delivery in the inner ear and releasing the first data demonstrating convincing hearing and vestibular function rescue in mice, we provide a foundation for other researchers interested in assessing the benefits of gene therapy in animal models of human disease.

What are the main findings? Response: Management of diabetes has improved in the past decades, studies have shown that mortality and cardiovascular disease among patients with diabetes has decreased, but these studies have not compared the trends among persons with type 1 diabetes and type 2 diabetes to those of the general population, where there have also been reductions in cardiovascular morbidity and mortality. We observed marked reductions in incidence for cardiovascular disease and mortality among individuals with diabetes, however, similar trends were observed for the general population. We observed a 43% (HR 1.43, 95% CI 1.25–1.62) greater event rate reduction for cardiovascular disease among individuals with type 1 diabetes compared to matched controls. The reduction in the rate of fatal outcomes did not differ significantly between patients with type 1 diabetes and controls, whereas patients with type 2 diabetes had a 13% (HR 0.87, 95% CI 0.85–0.89) lesser event rate reduction compared with matched controls. There was a 27% (HR 1.27, 95% CI 1.22–1.32) greater event rate reduction for cardiovascular disease among individuals with type 2 diabetes, compared with matched controls. Nevertheless, there remains a substantial excess overall rate of all outcomes analysed among persons with type 1 diabetes and type 2 diabetes, as compared with the general population.

MedicalResearch.com Interview with: [caption id="attachment_33863" align="alignleft" width="200"]Eric J. Brandt, MD Yale University Cardiovascular Disease Fellow Dr. Eric Brandt[/caption] Eric J. Brandt, MD Yale University Cardiovascular Disease Fellow MedicalResearch.com: What is the background for this study? What are the main findings? Response: From previous studies we know that industrial trans fatty acid (trans fat) consumption is linked to elevated risk for cardiovascular disease. Even small amounts of consumption can be deleterious to cardiovascular health. In New York state, there were 11 counties that restricted the use of trans fatty acids in eateries. We compared hospitalization for heart attacks and stroke from 2002 through 2013 in counties that did and did not have restrictions. Our study found that when comparing populations within New York state that restricted the use of trans fat, compared to those that did not, there was an associated additional decline beyond temporal trends for heart attacks and stroke events combined by 6.2%.

CHAIR, SWOG Professor, OHSU Knight Cancer Institute Marquam II Dr. Blanke[/caption] Charles D. Blanke, M.D., F.A.C.P., F.A.S.C.O. CHAIR, SWOG Professor, OHSU Knight Cancer Institute Marquam II MedicalResearch.com: What is the background for this study? What are the main findings? Response: Oregon’s Death with Dignity Act as a voter initiative which law in 1997 – the first of its kind in the nation. Now, physician aid-in-dying is spreading quickly, with the states of Washington, Vermont, Colorado, and California passing similar legislation, as well as the District of Columbia, and Montana (through a court ruling). Millions of Americans lives in states where they would have the opportunity, if they were terminally ill, to take a lethal dose of medication with a doctor’s prescription. My team here at SWOG, a global cancer research community that designs and conducts publicly funded clinical trials, wanted to look at Oregon’s 18 years of aid-in-dying data and answer some simple questions: Who is using the law? Why? Are the drugs effective? What are the trends in actually taking the prescribed medications? We found that use of law has mostly increased over time – and substantially increased in 2014 and 2015. We found that predominantly white, older, well-educated people, take advantage of the law, and many of them – 77 percent – have underlying terminal cancer. The medication is also 99.4 percent effective.

MedicalResearch.com Interview with: Keith Fluegge BS Institute of Health and Environmental Research (IHER) Cleveland Graduate School, The Ohio State University, Columbus Ohio MedicalResearch.com: What is the background for this study? What are the main findings? Response: The research letter discusses the possible link between rainfall precipitation and risk of autism. Earlier research suggested a link, although there remained quite a bit of skepticism surrounding the findings at the time. The purpose of the study was to briefly highlight the role of environmental exposure to the agricultural and combustion pollutant, nitrous oxide (N2O), as a possible etiological factor in neurodevelopmental disorders. We have published a series of epidemiological investigations, reviews, and correspondences discussing this possibility. In my continued research on this topic, I learned that rainfall and extreme weather-related events, like hurricanes, drive N2O emissions, especially from nitrogen amended soils. Exposure to this particular air pollutant may, therefore, plausibly undergird the relationship between rainfall precipitation and risk of autism.

What are the main findings? Response: Between 10-30% of healthcare costs are due to low value care, or patient care that provides little to no benefit to patients, and can sometimes cause harm (e.g., radiation exposure from diagnostic imaging tests). In this study, we found that hospital-based primary care practice provide more low value care than community-based primary care practices across the United States. Understanding where and why low value care occurs is going to be essential if we want to get serious about eliminating it.

Response: Stroke is the fifth leading cause of death in the United States, killing more than 130,000 Americans each year—that’s 1 of every 20 deaths—and costs the nation $33 billion annually, including the cost of health care services, medications, and lost productivity. And, stroke is leading cause of serious disability. An ischemic stroke, sometimes called a brain attack, is a stroke that occurs when there is a blockage of the blood supply to the brain.

Author Interviews, Hematology, Lancet / 09.04.2017

MedicalResearch.com Interview with: Dr. med. Kathleen Selleng, OÄ, QB Hämotherapie Universitätsmedizin Greifswald Institut für Immunologie und Transfusionsmedizin, Abt. Transfusionsmedizin Sauerbruchstraße Greifswald Deutschland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Red blood cell concentrates (RBCs) of blood group O RhD negative are frequently used as universal blood for emergency transfusions in patients with unknown blood type. This leads to an over-proportional use of these red blood cell concentrates and regular shortages of O RhD negative RBCs. Due to these shortages, patients with known RhD negative blood type sometimes have to be transfused with RhD positive RBCs. The present study shows that the overall risk to induce an anti-D by transfusing all emergency patients with unknown blood type with O RhD positive RBCs is in the range of 3 to 6%, while this risk is much higher (20-30%) in RhD negative patients which have to be transfused with RhD positive RBCs due to RhD negative RBC shortages.

MedicalResearch.com Interview with: [caption id="attachment_33749" align="alignleft" width="133"]Hanna Sahlin MSc, Lic psychologist, Lic psychotherapist Specialist in clinical psychology PhD-student Departement of Clinical Neuroscience Karolinska Institutet National Self-harm project Centre for Psychiatry Research, CPF Stockholm, Sweden Hanna Sahlin[/caption] Hanna Sahlin MSc, Lic psychologist, Lic psychotherapist Specialist in clinical psychology PhD-student Departement of Clinical Neuroscience Karolinska Institutet National Self-harm project Centre for Psychiatry Research, CPF Stockholm, Sweden What is the background for this study? What are the main findings? Response: This study is the result of wanting to find a more conclusive answer to whether individuals who engage in non-fatal deliberate self-harm are more prone to aggression towards others. There has long been a debate on whether aggression to oneself and aggression towards others co-occur, but the studies that have been conducted thus far have been on smaller samples or with clinical or forensic cohorts. Also, the studies have had great variability regarding the definition of both “deliberate self-harm” and “violence”. Thus, it has been difficult to establish an ”overall” effect size for this association, or to draw firmer conclusions on how and if this association plays out in the general population. We had the opportunity to study this association in several large nationwide population-based registries including all Swedish citizens, and with high specificity regarding the ingoing variables of interest – i.e., non-fatal deliberate self-harm (as registered in the National Patient Register) and violent crime convictions (as registered in the National Crime Register). We found a five times increased crude risk (hazard) of being convicted of a violent crime if one had received self-harm associated clinical care, and vice-versa, that there was an equally increased risk of self-harm if one had been convicted of a violent crime. After controlling for relevant psychiatric comorbidities and socio-economic status, an almost doubled risk of violent crime conviction remained among self-harming men and women compared to individuals not exposed to self-harm. It is important to notice that our study did not find any evidence suggesting that self-harm behaviours cause violent criminality. Therefore, we conclude that the engagement in violence towards oneself and towards others share an underlying vulnerability to impulsive and aggressive behaviours.

MedicalResearch.com Interview with: Dr. Nicholas Kassebaum, MD Assistant Professor Institute for Health Metrics and Evaluation University of Washington MedicalResearch.com: What is the background for this study? Response: Reducing deaths of young children has been an international priority over the past few decades, and much progress has been made in this regard. Comprehensive and timely measurement of death and disease burden among children and adolescents is essential for improving the health of young people. Analyzing the latest estimates from the Global Burden of Disease (GBD), the current study quantifies and describes levels and trends of mortality and disease burden among children and adolescents under the age of 19 from 1990 to 2015.

What are the main findings? Response: Over the few decades, there has been a substantial increase in the incidence of thyroid cancer. It is the fastest growing cancer and a recent study in JAMA found that the mortality rate has been rising. In 2006, Massachusetts passed healthcare reform, which expanded Medicaid, created new subsidized insurance programs for those ineligible for Medicaid and extended young adults eligibility on parental plans until the age of 26. The aim of our study was to evaluate the impact this has had on the treatment of thyroid cancer. To address this question, we used the Hospital Cost and Utilization Project State Inpatient Databases for Massachusetts, New Jersey, New York, and Florida, which included a cohort of 56,581 inpatient admissions from 2001 to 2011. We then compared these states before and after the healthcare reform in Massachusetts to evaluate the effect the healthcare reform had on the treatment of thyroid cancer.
Author Interviews, Memory, Nature, PTSD / 05.04.2017

MedicalResearch.com Interview with: Dominik R Bach, PhD, MD University of Zurich MedicalResearch.com: What is the background for this study? What are the main findings? Response: Posttraumatic stress disorder (PTSD) can occur after a psychological trauma such as physical violence, abuse, or natural disaster. It is characterised by increased arousal, flashbacks, and nightmares that reflect memories of the trauma. Current therapies include talking therapy, but it is costly and does not work in everybody. This is why we were looking for ways of reducing aversive memories with a drug. In the current study, we found that the antibiotic doxycycline impairs the formation of negative memories in healthy volunteers. To form memories, the brain needs to strengthen connections between neurons. It has recently emerged that for strengthening such connections particular proteins are required that sit between nerve cells, so-called MMPs. They are involved in many disorders outside the brain, such as certain cancers and heart disease. This is how we already know that doxycycline suppresses the activity of MMPs. Since doxycycline is relatively safe and readily accessible, our research was relatively straightforward. 76 healthy volunteers - half women, half men - came to the laboratory and received either placebo (a sugar pill) or 200 mg doxycycline. They then took part in a computer test in which one screen color was often followed by a mildly painful electric shock and another color was not. A week later, volunteers came back to the lab. They were shown the colors again , this time followed by a loud sound but never by shocks. The loud sounds made people blink their eyes - a reflexive response to sudden threat. This eye blink response was measured. Volunteers who had initially been under placebo had stronger eye blink after the color that predicted electric shock than after the other color. This "fear response" is a sensitive measure for memory of negative associations. Strikingly, the fear response was 60% lower in participants who had initially taken doxycycline.

Dr. Ann Kurth[/caption] Dr. Ann Kurth, Task Force member Dean of the Yale School of Nursing Adjunct professor New York University College of Nursing and the College of Global Public Health. MedicalResearch.com: What is the background for this study? Response: Celiac disease, an immune disorder where people should not eat food with gluten, is fairly prevalent. When people with celiac disease eat foods containing gluten, which is found in wheat, rye and barley, their body responds by inflaming or destroying villi—the tiny, fingerlike projections on the inner lining of the small intestine–which prevents the body from absorbing the necessary nutrients from food.

MedicalResearch.com Interview with: Alessandro Paoletti Perini, MD, PhD and Valentina Kutyifa MD, PhD University of Rochester Medical Center Heart Research Follow-Up Program Rochester, New York, 14642 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The present study is a pre-specified sub-study of the Multicenter Automatic Defibrillator Implantation Trial – Reduce Inappropriate Therapy (MADIT-RIT), which was published on the New England Journal of Medicine in 2012. The main trial showed that innovative ICD programming was associated with reduction in inappropriate ICD therapy and mortality. In the present investigation we focused on the detrimental effects that ICD firings, either appropriate or inappropriate, may have on patients’ psychological well-being. We observed that multiple appropriate and inappropriate shocks are associated with increased levels of ICD-related anxiety, a specific kind of psychological disorder which affects patients implanted with an ICD. Multiple appropriate ATP were also proved associated with higher anxiety, although not as much as shocks. On the other hand, we did not find a significant association with anxiety for multiple inappropriate ATP.

MedicalResearch.com Interview with: John Wittenborn Senior research scientist NORC's Public Health Analytics University of Chicago MedicalResearch.com: What is the background for this study? What are the main findings? Response:The emergence of anti-VEGF treatment for wet-form AMD (choroidal neovascularization) has had a dramatic impact on preserving vision for many Americans. However, community-based studies show that most patients are not diagnosed with wet-form AMD until they have already lost a significant, and largely unrecoverable amount of their vision.  Early detection of wet-form AMD is key to effective treatment and the preservation of vision. The ForeseeHome telemonitoring technology provides patients with a means to check their own eyes on a daily basis to detect the earliest signs of vision loss from wet-form AMD. This is a novel technology that has the potential to improve visual health outcomes for AMD patients.  A prior clinical trial (the AREDS-2 HOME study) demonstrated that this technology can detect wet-form AMD earlier, and with less vision loss than standard care alone. However, that is exactly where that study ended as it reported no cost information nor follow-up. Since the end of this study, the device has been cleared by the FDA and approved for reimbursement by Medicare for certain higher risk patients, but no study has yet considered the long-term implications of adoption of this technology. In our analysis, we use a computer simulation model to essentially estimate what will come next, after patients realize earlier detection of wet-form AMD by utilizing home monitoring. Basically, we follow simulated patients from the time they begin monitoring for the rest of their lives, recording the likely impacts of home monitoring on patients’ long term outcomes including visual status, costs and quality of life. We find that home telemonitoring among the population indicated for reimbursement by Medicare would cost $35,663 per quality adjusted life year (QALY) gained.  Medicare would expect to incur $1,312 in net budgetary costs over 10 years for each patient who initiates monitoring.  However, Medicare patients may expect to achieve lifetime net savings when accounting for the chance of avoided vision loss and its associated costs later in life.

MedicalResearch.com Interview with: [caption id="attachment_33615" align="alignleft" width="134"]Tine Vertommen, Criminologist Faculty of Medicine and Health Sciences Universiteitsplein 1 Antwerp, Belgium Tine Vertommen[/caption] Tine Vertommen, Criminologist Faculty of Medicine and Health Sciences Universiteitsplein 1 Antwerp, Belgium MedicalResearch.com: What is the background for this study? What are the main findings? Response: A recent prevalence study into interpersonal violence against child athletes in the Netherlands and Belgium showed that 6% experienced severe sexual violence, 8% experienced severe physical violence, and 9% of respondents experienced severe psychological violence in sport (Vertommen et al., 2016). While general literature has repeatedly shown that exposure to interpersonal violence during childhood is associated with mental health problems in adulthood, this relationship has not yet been demonstrated in (former) athletes. Thus, the objective of the current study is to assess the long-term consequences of these experiences on adult mental health and quality of life.
