MedicalResearch.com Interview with: [caption id="attachment_49481" align="alignleft" width="150"]Dr-Jung Min Bae Dr. Jung Min Bae[/caption] Jung Min Bae, MD, PhD Associate Professor, Department of Dermatology St. Vincent's Hospital College of Medicine, The Catholic University of Korea  MedicalResearch.com: What is the background for this study? Response: Vitiligo is a common chronic skin disease affecting 1% of the population, and it causes low self-esteem and social stigma. To date, there are no approved drugs for the treatment of vitiligo, even though growing evidence indicates favorable therapeutic responses of topical calcineurin inhibitors (TCIs) including tacrolimus and pimecrolimus. In this study, we conducted a systematic review and meta-analysis of all relevant prospective studies (n = 46) and identified remarkable therapeutic responses of TCI monotherapy and TCI plus phototherapy for vitiligo.

Povsic, MD, PhDInterventional CardiologistDuke Clinical Research InstituteDuke University School of MedicineDurham, North Carolina  Dr. Povsic[/caption] Thomas J. Povsic, MD, PhD Interventional Cardiologist Duke Clinical Research Institute Duke University School of Medicine Durham, North Carolina  MedicalResearch.com: What is the background for this study?  Response: The background for this study is that it is unknown how mandatory reporting of CYP2C19 metabolizer status affects how doctors treat patients or to what degree provision of this information would affect choice of a P2Y12 inhibitor within a clinical trial. As part of the GEMINI-ACS trial, all patients underwent CYP2C19 metabolizer testing.  This trial enrolled patients with a recent acute coronary syndrome and randomized them to aspirin or a low dose of rivaroxaban.  All patients were also to be treated with ticagrelor or clopidogrel, which was at the discretion of the investigator.  Investigators were given information regarding the CYP2C19 metabolizer status about a week after randomization.  Importantly prior to randomization, all investigators were asked how they expected to use this information, and then we followed what they actually did.

MedicalResearch.com: What is the background for this study? What are the main findings? Response: Accelerated approval pathway from the FDA allows cancer drugs to come to market sooner by showing improvement in surrogate measures such as change in tumor size. Surrogate measures do not reflect clinical benefit in terms of living longer or feeling better. So, when a drug receives accelerated approval, the drug is required to undergo a confirmatory trial to confirm that true clinical benefit from the drug actually exists. Last year, a paper from the FDA argued that accelerated approval pathway is working effectively because 55% of such drugs confirmed clinical benefit. However, we saw that most of those drugs were actually improving only a surrogate measure even in confirmatory trials. So the confirmatory trials were not confirming clinical benefit but actually confirming benefit in a surrogate endpoint. We investigate that issue in our study using updated results from the confirmatory trials that were ongoing at the time of FDA review. Our main finding is that only one-fifth of cancer drugs that received accelerated approval actually improved overall survival later in confirmatory trials. For, 20% of other drugs, the confirmatory trials tested the same surrogate endpoint as did the preapproval trial. For another 21%, the confirmatory trial showed benefit in a surrogate endpoint different from the one used in preapproval trial. Furthermore, when drugs fail to confirm clinical benefits in confirmatory trials, they still continue to remain on market. 
Author Interviews, Exercise - Fitness, JAMA, Mental Health Research, Pediatrics, UCLA / 29.05.2019

MedicalResearch.com Interview with: Molly C. Easterlin, MD Fellow, UCLA National Clinician Scholars Program Clinical Instructor, Pediatrics, Cedars-Sinai Medical Center  MedicalResearch.com: What is the background for this study? Response: Adverse childhood experiences or ACEs (including physical or emotional neglect or abuse, sexual abuse, domestic abuse, exposure to household substance misuse or mental illness, parental separation or divorce, and parental incarceration) are common with about half of children experiencing 1 and one-quarter of children experiencing 2 or more. Children exposed to adverse childhood experiences have worse mental health throughout life, including higher rates of depression and anxiety. However, little is known about what factors improve long-term mental health in those exposed to ACEs. Additionally, as far as we are aware, no studies have looked at team sports participation as a potential factor that may be associated with improved mental health among those with adverse childhood experiences.

What are the main findings?  Response: Lipid testing plays a major role in cardiovascular disease (CVD) risk screening, prediction, and treatment. In the past decade, several pivotal studies (including the Women’s Health Study, the Copenhagen City Heart Study, and the Copenhagen General Population Study) compared populations of individuals who had fasting lipid testing with populations of individuals who had nonfasting lipid testing, and found that non-fasting lipids were at least as good as fasting lipids in cardiovascular risk screening and predicting CVD risk. To date, however, no study has examined the cardiovascular predictive value of lipids measured on the same individuals who had both fasting and nonfasting lipid testing. This is important because individual-level variability in fasting versus nonfasting lipids may not be captured when looking at population-level risk associations, and evidence from randomized studies is lacking. Furthermore, it is unclear whether substituting nonfasting lipids would misclassify cardiovascular risk for individuals who may be eligible for statin therapy.

This prompted us to tailor and streamline an MBI specifically for surgeons, and to test it in our trainees.
Author Interviews, Frailty, Hospital Readmissions, JAMA, Stanford, Surgical Research / 27.05.2019

MedicalResearch.com Interview with: hospital-frailty-surgeryKara Anne Rothenberg.MD Postdoctoral Research Fellow, Vascular Surgery Shipra Arya, MD SM FACS Associate Professor of Surgery Stanford University School of Medicine MedicalResearch.com: What is the background for this study? Response: There is a growing body of literature showing that frailty, a syndrome where patients have increased vulnerability to a stressor (such as surgery), is associated with increased postoperative complications, failure to rescue, and hospital readmissions. The Risk Analysis Index (RAI), is an easy to use frailty measurement tool that better predicts postoperative mortality than age or comorbidities alone. As the rates of outpatient surgeries rise nationwide, we noted that most of the surgical frailty studies focus only on inpatient surgeries. Elective, outpatient surgery is generally considered low risk for complications and unplanned readmissions, however we hypothesized that for frail patients, it might not be.

MedicalResearch.com Interview with: [caption id="attachment_49363" align="alignleft" width="128"]Lenore J. Launer, PhD.Chief Neuroepidemiology Section Intramural Research ProgramNational Institute on Aging Dr. Launer[/caption] Lenore J. Launer, PhD. Chief Neuroepidemiology Section Intramural Research Program National Institute on Aging MedicalResearch.com: What is the background for this study? What are the main findings? Response: The prevalence of cerebral infarction on MRI can be as high as 30% in community-based studies. These lesions detected on brain MRI, are often clinically silent, but are associated with impairments in cognitive and physical function and can increase the risk for clinical events. For a large number, the origin of these brain lesions is unknown. There is also a lack of population-based data on unrecognized myocardial infarction, which is associated with an increased for clinical coronary disease and mortality. Unrecognized MI was detected in 17% of participants using state-of-the-art cardia MRI, a more sensitive measure of the lesions, than the standard ECG. We investigated the contribution to these lesions of recognized and unrecognized myocardial infarction [MI] identified on cardiac MRI. We found both recognized and unrecognized myocardial infarction increased the risk for cerebral infarction, and that in particular unrecognized MI was associated with cerebral infarction of embolic origins of an unknown source. Given their prevalence, unrecognized MI may be an underestimated contributor to the risk for cerebral infarction in older persons.

Hearing loss is not included among the reported conditions. This runs counter to two of the NIH’s stated goals, according to researcher Jan Blustein (M.D., Ph.D.), professor of health policy and medicine at New York University’s Robert F. Wagner Graduate School of Public Service, in a Research Letter in the May 15th issue of the Journal of the American Medical Association Otolaryngology and Head & Neck Surgery. “First, the NIH is committed to transparency about how it divides funds across diseases and conditions,” said Dr. Blustein.  “Second, it has said that it will prioritize its funding to those conditions that cause the greatest disease burden.”  Hearing loss causes great disease burden, ranking 10th in the U.S. among all conditions as a contributor to Disability Adjusted Life Years (a widely-used measure of disease burden), according to the World Health Organization.

Response: Blood cholesterol is a critical initiator of atherosclerotic plaques in the arteries that can lead to heart attack in adulthood. It is well established that these changes in the blood vessels occur already in childhood. Thus, it is important to know the status of cholesterol levels in youth to inform public health efforts aimed at preventing cardiovascular disease in the population. In the US there have been changes in childhood obesity prevalence (which may worsen cholesterol levels), the food supply (such as reduction of trans fats which may improve cholesterol levels), and other factors in recent years. We therefore designed a study to examine trends in cholesterol levels among youth in recent years.

Response: There is some mixed evidence regarding whether state level tort reform reduces defensive medicine, or the practicing of medicine in such a way to reduce medical liability. This includes “positive” defensive medicine, or performing certain tests and procedures to reduce such liability. Other research finds that the perception of malpractice risk drives such defensive medicine, including the use of diagnostic imaging, such as CT scans and MRIs. I was interested in exploring what influenced the perception of this risk, hypothesizing that, for a physician, a report of an injury against one’s colleague might increase the perception of this risk and lead to an increase the use of diagnostic imaging.

Response: There has been a growing use of quality metrics and indices in the US healthcare system. Much attention has been paid to quality measurement programs used by public payors, however, the use of such programs by commercial payors is much less studied. "Centers of excellence" are one type of quality designation program that is growing in use by commercial payors where certain hospitals are determined to be "high quality" for a certain disease state or procedure based on meeting certain criteria. For some people, this is even impacting the choice of providers and hospitals they can use by payors. We evaluated centers of excellence programs from three large commercial payors, Aetna, Cigna and Blue Cross Blue Shield, targeted at cardiovascular diseases and interventions and examined publicly reported outcomes for all hospitals performing percutaneous coronary interventions (cardiac stenting) in New York State.

What are the main findings? Response: Interpersonal violence is a substantial public health issue across all socio-demographic and socioeconomic strata globally. A depth of prior studies have found that victims of childhood sexual abuse might have higher risks of re-experiencing sexual violence as adults. But the “re-victimization” phenomenon has been insufficiently examined among the rapidly growing aging populations. There lacks examinations about life-course violence experiences and the accumulative effect of which in older ages. Our study examined three most common forms of interpersonal violence (child maltreatment, intimate partner violence, and elder abuse) across the life span and found an interconnectedness among them. Individuals with a history of child maltreatment and/or intimate partner violence had two to six times higher risks of elder abuse compared to those without a past experience of the violence.

What are the main findings? Response: The background for this study is that we know cancer survivors are at risk for uninsurance or underinsurance and the most commonly cited reason for this is cost of insurance.  However, there have been no prior studies assessing from the patient perspective the reasons for not having insurance. In addition, there has been further recent controversy over the Affordable Care Act, including threats from the current administration to dismantle it.  Thus assessing the impact of the ACA among at risk populations including cancer survivors is timely.

Yu, MD, MMSc Assistant Professor,  Harvard Medical School Director, Bone Density Center Endocrine Unit, Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Roux-en-Y gastric bypass (RYGB) is a popular surgical weight loss procedure.  We have previously shown that gastric bypass leads to rapid high-turnover bone loss. Bariatric procedures are being increasingly performed in older adults, and the clinical consequences of gastric bypass-associated skeletal changes in this vulnerable population have been unclear to date.  Thus, we used Medicare claims data to investigate fracture risk among older adults after gastric bypass, and in comparison to adults who received another bariatric procedure called adjustable gastric banding (AGB), which is thought to have fewer negative bone effects. In our analysis, we found that patients undergoing Roux-en-Y gastric bypass were 73% more likely to fracture than those undergoing AGB. Importantly, we found that hip fracture risk increased nearly 180% after RYGB, and that fracture rates in patients aged 65 or older were similar to the overall group.

What are the main findings? Response: The use of high dose vitamin supplementation is popular in parts of the population, often without any clear indication and in the absence of clear evidence of benefit. However, side effects can occur, and in a previous published secondary analysis of double blinded randomized controlled trials, we found to our surprise an increased risk of hip fracture in those supplemented with high doses of vitamin B6 in combination with vitamin B12. This finding was re-assessed in the current study employing data from the large observational Nurses' Health Study. As in the previous study, we found that a combined high intake of vitamin B6 and B12 was associated with increased risk of hip fracture.

What are the main findings? Response: I read a very interesting paper back in 2006 “Detection and quantification of mutation in the plasma of patients with colorectal cancer”. Only some 60 % of patients with early colorectal cancer were detectable in this way whereas patients with stage IV disease all had a high concentration of APC mutations in their plasma. So the prospects of using the method for example, screening of primary colorectal cancer seemed limited but I thought wow, this is the test to detect recurrences and generalized disease during follow-up after surgery for colorectal cancer. After some discussion we started to collect plasma samples from patients at the hospital where I worked and that´s how my research began.

Meister Child Health Evaluation and Research Center University of Michigan, Ann Arbor MedicalResearch.com: What is the background for this study?   Response: Doctor and pharmacy shopping is a high-risk behavior in which patients obtain opioid prescriptions from multiple prescribers and fill them at multiple pharmacies. Because this behavior is associated with a high risk of overdose death, there have been many efforts to help clinicians detect doctor and pharmacy shopping among patients prescribed opioids. For example, 49 states have a prescription drug monitoring program that provides information on patients’ prior controlled substance prescriptions. In contrast, there has been little attention to the possibility that patients prescribed opioids may have family members who are engaged in opioid doctor and pharmacy shopping. Such family members may divert opioids prescribed to patients because of their access to these opioids.

MedicalResearch.com Interview with: Dr-Romy GaillardRomy Gaillard MD PhD LifeCycle Project-Maternal Obesity and Childhood Outcomes Study Group Erasmus MC MedicalResearch.com: What is the background for this study?   Response: Obesity among women of reproductive age is a major problem for society. Scientists have long known that maternal weight before and during pregnancy are associated with pregnancy outcomes. Gestational weight gain is necessary to ensure healthy development of the fetus, but too much weight gain is associated with a higher risk of pregnancy complications. The magnitude of the associations of maternal weight before and during pregnancy with the risks of pregnancy complications, as well as the optimal amount of weight that especially obese women should gain during pregnancy were not well-known.

Response: Adolescence is a time when teens begin to take charge of their health, but it is also a time when they can be prone to health risk behaviors, such as insufficient physical activity, poor sleep, and substance use. We were interested in whether using an electronic health risk screening tool in primary care settings could improve healthcare and health for adolescents.  The tool was designed to provide screening as well as motivational feedback directly to adolescents, in addition to clinical decision support for the healthcare clinician.  We conducted a trial with 300 adolescent patients where one group received the screening tool prior to their health checkup, and the other group received usual care.

Author Interviews, Cancer Research, Colon Cancer, JAMA / 07.05.2019

MedicalResearch.com Interview with: Prof. Dr. med. Hermann Brenner Clinical Epidemiology and Aging Research Division Head German Cancer Research Center Foundation under Public Law Germany  MedicalResearch.com: What is the background for this study? Response: Colorectal cancer is the third most common cancer globally, accounting for almost 900.000 deaths every year. Most of these deaths could be prevented by screening colonoscopy with early detection and removal of precursors of the cancer. However, capacities and use of screening colonoscopy are limited in most parts of the world, and low-cost but reliable noninvasive screening tests are important alternative primary screening tests. The currently best established noninvasive tests are fecal immunochemical tests for hemoglobin (FITs) which are offered for colorectal cancer screening in an increasing number of countries. Although FITs detect the majority of colorectal cancers they detect approximately one out of four advanced adenomas only, the precursors of most colorectal cancers. We hypothesized that this proportion could be increased by taking a single pill of aspirin two days prior to collecting the stool sample for FIT, because the well-established antithrombotic effects of aspirin might favor detecting occult bleeding from colorectal cancer or its precursors.

FDA has provided guidance that sunscreen active ingredients with systemic absorption greater than 0.5 ng/mL or with safety concerns should undergo nonclinical toxicology assessment including systemic carcinogenicity and additional developmental and reproductive studies. This randomized clinical trial demonstrated systemic exposure of 4 commonly used sunscreen active ingredients on application of sunscreen products under maximal use conditions consistent with current sunscreen labeling. All 4 sunscreen active ingredients tested resulted in exposures exceeding 0.5 ng/mL.

Shaker, MD Associate Professor of Pediatrics Associate Professor of Community and Family Medicine Dartmouth-Hitchcock Medical Center MedicalResearch.com: What is the background for this study? Response: There are two peanut allergy treatments that are being evaluated for potential FDA approval—an orally administered treatment and an epicutaneous (skin based) treatment.  Both have tremendous potential benefit.  The focus of our study was to explore the range of health and economic benefits in terms of establishing pathways for how each therapy could be cost effective. We want to be clear that our purpose was not to suggest one therapy is or is not cost effective at present.  That would be a ridiculous statement to make regarding two treatments that not only lack FDA approval, but do not have established pricing.  Rather, we used preliminary inputs that are presently available to create as robust a model as we could to better determine the individual paths that would make them more or less cost-effective.

Simpkin,  MD, MMSc Associate Director, Center for Educational Innovation and Scholarship, MGH Associate Program Director, Education and Curriculum, Internal Medicine Residency, MGH Instructor in Medicine, Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? Response: The academic health care environment has changed in unprecedented ways over several decades, with mounting evidence that faculty are becoming increasingly more unhappy, dissatisfied, and burnt out in their work. Concern for faculty wellbeing is high, with much speculation about causes of burnout. Comprehending what affects satisfaction at work in academic health care centers is critically important to stem this epidemic of discontent. For physicians, satisfaction has been reported to be associated with quality of care delivered, particularly as measured by patient satisfaction; faculty retention and job satisfaction are intricately linked, with dissatisfied physicians more likely to leave the profession and to discourage others from entering. Other industries that have suffered similar rises in employee discontent have found that demonstration of respect is the most important leadership behavior in improving employees satisfaction. To our knowledge this factor has not been looked at in healthcare professionals. To address this gap, we sought to determine key variables influencing satisfaction at work for faculty in a large academic medical center in the United States.

What are the main findings?  Response: Effective allocation of public health resources during an outbreak is complicated and often reactive. Thus, it is important that we develop quantitative tools that can accurately and rapidly forecast the progression of an outbreak and provide decision support. Recently, several advancements have been made in the realm of infectious disease forecasting: it is a field that is growing in exciting directions. However, for these forecasting tools to work in real time, we must understand how the forecasting apparatus and observational network work in real time to ensure they are sufficient to support accurate operational predictions. We previously showed that accurate and reliable forecasts of West Nile virus outbreaks can be made using surveillance data and a mathematical model representing the interactions between birds, mosquitoes and risk of human spillover. This model system was able to retrospectively forecast mosquito infection rates prior to the week of peak mosquito infection, and to forecast accurately the seasonal total number of human West Nile virus cases prior to when the majority of cases were reported. For this study, we were interested in the data flow process and the question of whether appropriate infrastructure is in place to support real time forecasting. If this forecast system were made operational in real time, public health officials would have an evidence-based decision-support tool to help 1) actively target control of infected mosquito populations (i.e., larviciding and adulticiding), 2) alert the public to future periods of elevated West Nile virus spillover transmission risk, and 3) identify when to intensify blood donor screening.
