MedicalResearch.com Interview with: Dr. Judy Karp, Dr. Antonio Wolff and  Dr. Kala Visvanathan Breast Cancer Program Johns Hopkins Sidney Kimmel Comprehensive Cancer Center Baltimore, MD 21287 Medical Research: What is the background for this study? What are the main findings? Response: The background for this study was the clinical observation from the Johns Hopkins Leukemia Program that a significant number of women with newly diagnosed acute myeloid leukemia had a personal history for breast and/or ovarian cancers.  This observation led to our examination of the large NCCN breast cancer database in a multidisciplinary and multi-institutional study.  The overarching finding in our study is that the risk of developing some form of leukemia following chemotherapy with or without radiation therapy, while small, continues to increase over at least 10 years without a plateau and is roughly twice what we thought it to be from previous breast cancer studies.

Dr. Amit Navin Vora MD, MPH Third Year Cardiovascular Fellow John Hopkins UniversityMedicalResearch.com Interview with: Dr. Amit Navin Vora MD, MPH Third Year Cardiovascular Fellow John Hopkins University   Medical Research: What is the background for this study? What are the main findings? Response: Current guidelines recommend timely reperfusion in patients presenting with ST-elevation myocardial infarction, with primary PCI being the preferred method if delivered in an expedient fashion. Otherwise, guidelines recommend that eligible patients should be treated with fibrinolysis prior to transfer to a PCI capable hospital. In our study, we used Google Maps to estimate drive times between the initial presenting hospital and the PCI-capable hospital looked at the association between estimated drive time and reperfusion strategy (primary PCI or fibrinolysis) selection. We found that less than half of eligible patients with an estimated drive time of more than 30 minutes received primary PCI in time, and only half of patients with more than an hour’s drive received lytics before transfer. This suggests that neither primary PCI nor pre-transfer fibrinolytic therapy is being used optimally. Among eligible patients with a drive time of 30-120 minutes, we found no significant mortality difference but higher bleeding risk among patients receiving lytics prior to transfer; this increased bleeding risk was focused in patients that required rescue PCI.

MedicalResearch.com Interview with: Eric Wan BS and Miceile Barrett BS Johns Hopkins University School of Medicine Baltimore, MD Medical Research: What is the background for this study? What are the main findings? Answer: Access to surgery is limited in resource-poor settings and low-and-middle income countries (LMICs) due to a lack of human and material resources. In contrast, academic hospitals in high-income countries often generate significant amounts of unused and clean medical supplies that cannot be re-used in the operating rooms of high-income countries. Programs such as Supporting Hospitals Abroad with Resources and Equipment (SHARE) provide an avenue for recovery of these supplies and donation to resource-poor hospitals in LMICs. From data collected from SHARE supplies donated by Johns Hopkins, we found that the nationwide impact for these programs to be $15.4 million among US academic hospitals, which accounts for only 19 categories of commonly recovered supplies. When we tracked our donated supplies to hospitals in Ecuador serving the poor, we found that the cost-effectiveness of these donations was US $2.14 per disability-adjusted life-year prevented.

Bleich, Ph.D. Associate Professor Department of Health Policy and Management Johns Hopkins Bloomberg School of Public Health Baltimore, MD 21205 Medical Research: What are the main findings of the study? Dr. Bleich: Providing easily understandable calorie information — particularly in the form of miles of walking — makes adolescents more likely to buy a beverage with fewer calories, a healthier beverage or a smaller size beverage. Adolescents were also more likely to not buy any drink at all after seeing the signs with calorie information. (more…)

MedicalResearch.com Interview with: Sosena Kebede, MD, MPH Assistant Professor of Medicine, Department of Medicine Associate Faculty, the Armstrong Institute for Patient Safety and Quality, Johns Hopkins School of Medicine Faculty, Department of Health Policy and Management and Baltimore, MD 21287Sosena Kebede, MD, MPH Assistant Professor of Medicine, Department of Medicine Associate Faculty, the Armstrong Institute for Patient Safety and Quality, Johns Hopkins School of Medicine Faculty, Department of Health Policy and Management and Baltimore, MD 21287 Medical Research: What are the main findings of the study? Dr. Kebede: There were 3 main findings in this study: 1.       Patients’ understanding of aspects of their hospital care is suboptimal on the domains of knowledge of diagnoses, indications for the medications they take and the types of procedures/tests they get. Some forms of poor shared understanding could have potentially serious implications for their health and for future care such as identifying a prescribed antidepressant as a blood thinner or mistaking an echocardiogram a left heart catheterization or thinking a liver cyst is a liver cancer. Other forms of poor shared understanding such as not accurately identifying why a procedure is done or what the results of the procedure show (a finding not discussed in the research letter) may seem less consequential  but raise the issue of informed consent, patient empowerment and may alsoraise questions about patient and physician behavior towards appropriate use of in-patient procedures. Some of the questions we could ask here include: would patients demand more or less procedures if they had better understanding of what the procedures entail, and why they are beingordered? Conversely, would physicians recommend more or less of in-patient procedures, when they encounter patients whose understanding of procedure indications are optimal? (more…)

Dr. Li-Ching Lee: This population-based case-control study in young children provides evidence that prenatal selective serotonin reuptake inhibitor (SSRI) use may be a risk factor for autism and other developmental delays (DD). Among boys, prenatal SSRI exposure was nearly 3 times as likely in children with autism spectrum disorder (ASD) relative to children with typical development; the strongest association occurred with first-trimester exposure. Exposure was also elevated among boys with DD and was strongest in the third trimester. (more…)

Angelo M. De Marzo MD PhD Professor of Pathology Johns Hopkins School of Medicine Baltimore, MD 21231MedicalResearch.com Interview with: Angelo M. De Marzo MD PhD Professor of Pathology Johns Hopkins School of Medicine Baltimore, MD 21231 MedicalResearch.com: What are the main findings of the study? Dr. De Marzo: Working as a team with Dr. Elizabeth Platz and a group of other investigators we found that men with chronic inflammation in their benign areas of their prostate biopsies had a higher chance of prostate cancer,  and especially higher grade cancers, which are associated with disease aggressiveness. A key unique aspect of the study is that the samples were taken from man who were enrolled in the Prostate Cancer Prevention Trial (PCPT), a trial in which all men entering the study had a relatively low PSA, and, all men at the end of study who did not already have a diagnosis of prostate cancer were offered a prostate biopsy regardless of their PSA. This study design, unlike a standard association study, allowed us to minimize the potential bias whereby inflammation is associated itself with elevations in PSA. In this standard design approach, when cancer is detected it could artifactually appear that inflammation is associated with cancer because the inflammation was in part driving the PSA elevation, which prompted the biopsy in which cancer was detected.

Dr Damian Hoy University of Queensland School of Population Health Herston, AustraliaMedicalResearch.com Interview with: Dr Damian Hoy University of Queensland School of Population Health Herston, Australia

MedicalResearch.com: What are the main findings of the study? Dr. Hoy: The study was part of the Global Burden of Disease 2010 study, which was conducted by the University of Queensland, Harvard University, Johns Hopkins University, University of Washington, and hundreds of disease experts throughout the globe. It is the largest ever public health study. It compared the overall burden (in terms of both death and disability) of the most common 291 diseases/conditions in the world. Low back pain was found to cause more global disability than any other disease/condition. If this is something you are going through, it may be worth knowing that marijuana strains for back pain is one of the most powerful remedies. You've possibly tried everything in the shop and over the counter medicine. So why not give this a go and see how you get on. There's no harm in trying. Global disability from low back pain is increasing. There is an urgent need for global, regional and national agencies to pay far greater attention to the disability caused by low back pain. In the developed world there are low back pain therapy treatments available whereas, in the developing world things aren't as accessible. (more…)

Samuel R. Friedman PhD Institute of Infectious Disease Research National Development and Research Institutes, Inc. New York, NY Department of Epidemiology Johns Hopkins Bloomberg School of Public Health, Baltimore, MDMedicalResearch.com Interview with: Samuel R. Friedman PhD Institute of Infectious Disease Research National Development and Research Institutes, Inc. Ny, NY Department of Epidemiology Johns Hopkins Bloomberg School of Public Health Baltimore, MD MedicalResearch.com: What are the main findings of the study? Dr. Friedman: The main finding is that programs that helped protect people who inject drugs from HIV and those that helped them to get medical care seem to be associated with less HIV disease and less death related to HIV disease among the heterosexual population of large United States metropolitan areas. This is important.  Drug users in the US are widely despised, and their has been a lot of political opposition to programs like syringe exchange and drug abuse treatment. Our findings show that these programs are associated with better health and less death in the broader population.  It makes more sense to help people--even those you despise--stay uninfected, and to get medical care, than to restrict or attack programs for them.

MedicalResearch.com Interview with: Dr. Richard P. Allen Department of Neurology Johns Hopkins University Baltimore, MD 21224, MedicalResearch.com: What are the main findings of the study? Dr. Allen:  This study should serve to change medical practice by reducing use of pramipexole and ropinirole to avoid the insidious worsening of restless legs syndrome that occurs for many on these drugs. Pramipexole (Mirapex) a medication that mimics dopamine in the brain  in usual therapeutic doses for treatment of restless legs syndrome (RLS) works at first but over time one year makes the disease worse for up to 9% of the patients on 0.5 mg a day. Pregabalin (Lyrica) an anti-convulsant and pain drug  that works on a calcium channel in the brain in therapeutic dose for RLS (300 mg a day) does not make the disease worse  (There is some natural progression of the disease shown to occur fro 1 - 2% or patients over a year.. seen in this study). Pregabalin is in the short run as effective as pramipexole (over 12 weeks) and in the long run over 52 weeks more effective. These results confirm what had been expected that the dopamine drug pramipexole makes worse Restless Legs Syndrome while a drug not directly acting on the dopamine system does NOT make restless legs syndrome worse.

Hammond, MD, PhD, MPH Research Associate International Center for Spinal Cord Injury Hugo W. Moser Research Institute at Kennedy Krieger Institute Baltimore, MD 21205. MedicalResearch.com: What are the main findings of the study? Researchers: ·    Between 2007 and 2010, the number of serious traumatic spinal cord injuries (TSCI) in the United States (U.S.) increased, doing so more rapidly among older adults (age ≥65 years) compared to younger adults (age <65 years). Injuries from falls have overtaken motor vehicle crashes as the main cause of adult TSCI. ·    Older adults are more likely to experience worse outcomes compared to younger adults even after taking into account severity and mechanism of injury, as well as other co-morbid conditions. Older adults are 4 times more likely to die in the emergency room, and if admitted to inpatient care, they are 6 times more likely to die as inpatients compared to younger adults. ·    Emergency room charges for treatment of acute TSCI among adults increased 20% from $3,342 per encounter in 2007 to $4,024 per encounter in 2010 even after accounting for the cost of inflation.

Dr Ginsburg: This study examined the long-term outcomes of youth treated for an anxiety disorders. Findings revealed that almost half of anxious youth treated for an anxiety disorder were in remission (i.e., did not meet diagnostic criteria for any of the three study entry anxiety disorders) at an average of six years since starting treatment. Youth showing clinically meaningful improvement after 12 weeks of treatment, were more likely to be in remission, had lower anxiety severity, and had better functioning compared to youth who showed minimal or no initial clinical improvement. Treatment type did not affect long-term outcomes. (more…)

Madhav Goyal MD, MPH Assistant Professor General Internal Medicine Johns Hopkins School of MedicineMedicalResearch.com Interview with: Madhav Goyal MD, MPH  Assistant Professor General Internal Medicine Johns Hopkins School of Medicine MedicalResearch.com: What are the main findings of the study? Dr. Goyal:
  • The evidence is moderately strong that there is a small but consistent benefit for mindfulness meditation programs to improve 3 symptoms: anxiety, depression, and pain.  We found low level evidence that mindfulness meditation helps with symptoms of stress and distress, as well as with the mental health dimension of quality of life.
  • For the symptoms of anxiety and depression for which we find moderate evidence of benefit, we need to keep in mind that most of the trials didn't study people with a clinical diagnosis of anxiety or depression (although a few did).  Most were studying diverse patient populations who may have had a low level of these symptoms, such as those with  breast cancer, fibromyalgia, organ transplant recipients, and caregivers of people with dementia.
  • We found about a 5-10% improvement in anxiety symptoms compared to placebo groups.  For depression, we found a roughly 10-20% improvement in depressive symptoms compared to the placebo groups. This is similar to the effects that other studies have found for the use of antidepressants in similar populations.
  • While we found that the evidence was moderately strong that mindfulness meditation programs may improve pain, there weren't as many trials evaluating chronic pain, and so we don't understand what kinds of pain this type of meditation may be most useful for.

Dr. Ahuja: Across the nation, laparoscopic colectomy is performed about as frequently as open colectomy, despite being associated with a lower complication rate and a lower overall hospital cost. On the other hand,  an exponentially growing prevalence was found with robotic colectomy, a procedure that has so far demonstrated only equivalent outcomes with laparoscopic colectomy but a higher overall cost.

Dr. Alexander:
  • There have been large shifts in the types of treatments used to treat Type 2 diabetes during the past decade in the United States.
  • We document large declines in the use of glitazones and sulfonylureas and important increases in the use of the newer DPP-4 inhibitors and GLP-1 agonists.
  • We also found large shifts in the types of insulins used, with substantial reductions in the use of regular and intermediate insulins, and large increases in the use of long-acting and ultra short-acting  therapies.
  • Costs have increased significantly over the past 5 years, driven primarily by insulin and DPP-4 inhibitors
  • All of these changes notwithstanding, biguanides continue to remain a mainstay of therapy. (more…)

Yogesh Moradiya MBBS From the Neurosciences Critical Care Division Johns Hopkins University, Baltimore, MD;MedicalResearch.com Interview with: Yogesh Moradiya MBBS From the Neurosciences Critical Care Division Johns Hopkins University, Baltimore, MD;   MedicalResearch.com: What are the main findings of the study? Answer: We studied 712,433 stroke cases in 6,839 hospital samples in United States over 11-year study period (2000-2010) and found that hospitals with neurology residency training program treated stroke patients with tissue plasminogen activator (tPA) more frequently than other teaching or non-teaching hospitals. The higher tPA utilization in hospitals with neurology residencies was independent of patient age, gender, ethnicity, insurance status, comorbidities, hospital geographic location, stroke case volume, calendar year and the Joint Commission Primary Stroke Center certification.

Dr. Atkinson: First, among a healthy cross-section of U.S. children, vitamin D deficiency defined as levels below 30 ng/mL (the currently accepted threshold for adequate vs. inadequate vitamin D) were associated with nearly twice the risk for anemia compared to those with sufficient vitamin D levels.  Secondly, when we looked specifically at Caucasian and African-American children, we found that children with the lowest vitamin D levels were at increased risk for anemia in both groups, but that the specific vitamin D level below which the anemia risk started to increase was much lower in the African-American children (12 ng/mL) than in the Caucasian children (20 mg/mL).

MedicalResearch.com Interview with: Ruth Tamrat, Minh-Phuong Huynh-Le, and Madhav Goyal Johns Hopkins University School of Medicine, MSIV MedicalResearch.com: What are the main findings of the study? Answer: Despite the known adverse effects of sleep deprivation on recovery from illness, studies have shown that sleep deprivation remains an incompletely addressed problem among inpatients.  Behavioral interventions are recommended as first line therapy prior to using pharmacologic therapy due to the adverse side effects of sedative hypnotics. This systematic review sought to identify the efficacy of non-pharmacologic interventions that have been used to improve the sleep of general inpatients.  The results of this review demonstrate a lack of high quality evidence regarding the efficacy of these non-pharmacologic interventions in improving the sleep quality or quantity of patients in the hospital.

MedicalResearch.com Interview with: Dr. Seth S. Martin, MD Division of Cardiology, Johns Hopkins Hospital 600 North Wolfe Street Baltimore, Maryland 21287 Johns Hopkins Hospital Baltimore, MD 21287. MedicalResearch.com: What are the main findings of the study? Dr. Martin: Our systematic review identified 16 studies for qualitative synthesis and 11 for quantitative synthesis. In individuals without baseline cognitive dysfunction, statins did not adversely affect memory when used in the short-term (<1 year). Long-term cognition studies including 23,433 patients with a mean exposure duration of 3 to 24.9 years showed a 29% relative reduction in incident dementia related to statin use (hazard ratio, 0.71; 95% CI 0.61-0.82) and a 2% absolute risk reduction (number needed to treat for 6.2 years: 50).

Matthew Daubresse, MHS Research Data Analyst Center for Drug Safety and Effectiveness Johns Hopkins School of Public Health 615 N. Wolfe Street, Suite W6023 Baltimore, MD 21205 MedicalResearch.com: What are the main findings of the study? Answer: Over the past decade, prescriptions for non-opioid medications remained stable or declined among ambulatory pain visits in the United States. In visits for new-onset musculoskeletal pain, non-opioid prescribing decreased from 38% of visits in 2000 to 29% of visits in 2010. During this time, opioid prescriptions nearly doubled. Few patient, provider, and visit characteristics were associated with the likelihood of opioid receipt, suggesting increases in opioid prescribing have occurred generally across different groups of patients.  (more…)

 Dr. Wise: The TIOSPIR trial was a landmark study, one of the largest ever conducted for chronic obstructive pulmonary disease (COPD).  It was designed to test the comparative safety and effectiveness of two delivery devices of tiotropium, a long-acting bronchodilator.  One formulation is the Respimat multi-dose soft mist inhaler and the other formulation is the single dose HandiHaler dry powder inhaler. After following more than 17000 patients for an average of 2.3 years, TIOSPIR showed that there was no difference in either the safety in terms of mortality or adverse cardiovascular events between the two devices.  Moreover, both devices showed similar effectiveness in terms of time to first COPD exacerbation. A lung function substudy in 1370 patients showed that the 5 microgram dose of Respimat was equivalent to the HandiHaler as a bronchodilator, but the 2.5 microgram dose was not quite as effective.

Harvard Stem Cell Institute's Kornelia Polyak, MD, PhD, MedicalResearch.com Interview with: Kornelia Polyak, MD, PhD Professor of Medicine Dana-Farber Cancer Institute Harvard Medical School Boston, MA 02215 MedicalResearch.com: What are the main findings of the study? Dr. Polyak: We found that when comparing normal breast tissue of women who have not had children (nulliparous) and those who had children in their early 20s, the largest changes are in breast epithelial progenitors. The frequency of these cells is lower in parous women (women who had children) and the properties are also altered in a way that they are less likely to proliferate. Women with high risk of breast cancer, such as BRCA1 and BRCA2 mutation carriers, have very high frequency of these cells, and also parous women who did get cancer have more than those who did not. These results indicate that the frequency of these cells may predict breast cancer risk. (more…)

Lee, MD MBA Associate Professor of International Health Director of Operations Research International Vaccine Access Center (IVAC) Johns Hopkins Bloomberg School of Public Health 855 N. Wolfe Street Suite 600 Baltimore, MD 21205Bruce Y. Lee, MD MBA Associate Professor of International Health Director of Operations Research International Vaccine Access Center (IVAC) Johns Hopkins Bloomberg School of Public Health 855 N. Wolfe Street Suite 600 Baltimore, MD 21205 MedicalResearch.com: What are the main findings of the study? Dr. Lee: Vancomycin resistant enterococci (VRE) is every hospital’s problem.  A VRE outbreak in one hospital, even if the hospital is relatively small or distant, can readily spread to other hospitals in a region because patients leaving one hospital often will go to other hospitals either directly or after an intervening stay at home.  These patients can then carry VRE with them to other hospitals.  Therefore, as long a single hospital has a problem with VRE or any other healthcare associated infection, all other hospitals are at risk.  Conquering VRE then requires cooperation among hospitals.

MedicalResearch.com Interview with: Nisa M. Maruthur, MD, MHS Assistant Professor of Medicine & Epidemiology The Johns Hopkins University Early Response to Preventive Strategies in the Diabetes Prevention Program MedicalResearch.com: What are the main findings of the study? Dr. Maruther: For patients engaged in a lifestyle intervention to prevent diabetes, weight loss early on (at 6 months) is an extremely strong predictor of whether they will develop diabetes down the road.  Even in the setting of substantial weight loss (>10%) at 6 months, it is still beneficial to lower fasting glucose.  These results are unique in that we previously understood that weight loss over time (years) is important to prevent diabetes, but now we know the impact of early weight loss on longer-term diabetes risk.
