MedicalResearch.com Interview with: Fudi Wang, M.D., Ph.D. Qiushi Chair Professor Nutrition Discovery Innovation Center School of Public Health/School of Medicine Zhejiang University Hangzhou 310058, ChinaFudi Wang, M.D., Ph.D. Qiushi Chair Professor Nutrition Discovery Innovation Center School of Public Health/School of Medicine Zhejiang University Hangzhou  China MedicalResearch.com: What is the background for this study? What are the main findings? Response: Parkinson disease (PD) is the second most common neurodegenerative disease affecting approximately 10 million people around the world. To date, the cause of PD remains poorly understood. It is reported that 90% PD cases have no identifiable genetic cause. What’s worse, few therapeutic advances for the treatment of PD have been made in the past decades. Nevertheless, growing prospective longitudinal studies shed lights on the potential beneficial effect of lifestyle factors on reducing the risk of developing Parkinson disease. In this study, we performed a a dose-response meta-analysis of more than half a million participants. We found that physical activity, particularly moderate to vigorous physical activity, could significantly reduce PD risk. (more…)

MedicalResearch.com Interview with: Julie Flom, MD MPH Clinical Fellow Division of Allergy & Immunology Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study?   Response: Women who are minorities and of lower socioeconomic have particularly high rates of exposure to chronic ongoing adversity such as poverty as well as traumatic stressors in their lifetime and are also more likely to have low birthweight infants.  Not all women exposed to chronic adversity or trauma transfer this risk to the next generation – it is primarily when the trauma results in changes in her bodies’ ability to handle ongoing stress that the developing child can be impacted. Our group undertook a study to investigate whether women with increased exposure to traumatic stressors over her lifetime were at higher risk of having low birthweight infants and also whether effects of trauma would only be evident among women who produced higher levels of cortisol, the major stress response hormone, while pregnant.

MedicalResearch.com Interview with: Michael F. Murray, MD, FACMG, FACP Director for Clinical Operations in the Center for Genomic Health Yale School of Medicine MedicalResearch.com: What is the background for this study? Response: Population screening for the cancer risk associated with the BRCA1 and BRCA2 genes has been suggested by some.  We screened a cohort of about 50,000 adult patient volunteers at Geisinger Health System in Pennsylvania for this risk.  (more…)
Author Interviews, Heart Disease, JAMA, OBGYNE, Pediatrics / 22.09.2018

MedicalResearch.com Interview with: Eyal Cohen, MD, MSc, FRCP(C) Associate Scientist and Program Head (interim), Child Health Evaluative Sciences Research Institute, The Hospital for Sick Children Staff Physician, Division of Paediatric Medicine, The Hospital for Sick Children Professor, Paediatrics and Health Policy Management & Evaluation The University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Response: Having a child with a major birth defect can be a life-changing and stressful event for the child's mother.  This stress may be associated with higher risk of premature cardiovascular disease. We found that mothers of infants born with a major birth defect had a 15% higher risk of premature cardiovascular disease that a comparison group of mothers.  The risk was more pronounced, rising to 37% among mothers who gave birth to a more severely affected infant (and infant born with major birth defects affecting more than one organ system). The risk was apparent even within the first 10 years after the birth of the child.

Author Interviews, Endocrinology, JAMA, Prostate Cancer, UCLA / 22.09.2018

MedicalResearch.com Interview with: Amar U. Kishan, MD Assistant Professor Department of Radiation Oncology University of California, Los Angeles MedicalResearch.com: What is the background for this study? What are the main findings? Response: Three large randomized trials demonstrated an overall survival (OS) benefit when androgen deprivation therapy (ADT) is combined with radiotherapy (RT) for high-risk prostate cancer (PCa). The duration of ADT in these seminal studies ranged from six months to lifelong. Because ADT has multiple attendant adverse effects--including bone loss, altered metabolism, diminished muscle mass, gynecomastia, hot flashes, and possibly increased cardiovascular events--shortening the duration of ADT without compromising oncologic effectiveness has been an area of active study. Five trials have compared various durations of ADT, reaching conflicting conclusions with respect to overall survival outcomes, with some suggesting an improvement with longer durations of ADT and others failing to show a uniform survival benefit. Most of these trials have amalgamated Gleason grade group 4 (Gleason score 8) PCa with Gleason grade group (GG) 5 (Gleason score 9-10) PCa. Emerging data indicate that GS 9-10 PCa constitutes a distinct subset of high-risk PCa with inferior outcomes and earlier progression than GS 8 disease. With the knowledge that GS 9-10 PCas constitute a distinct, more aggressive form of PCa, one might hypothesize that longer durations of ADT may be more advantageous in both augmenting local control and controlling potential micrometastatic disease. Alternatively, as GS 9-10 lesions by definition contain highly de-differentiated Gleason pattern 5 disease foci and may proceed to a castrate-resistant state more rapidly, one may also hypothesize that GS 9-10 lesions are less responsive to ADT, and longer durations may be counter-productive. In order to identify differences in the impact of ADT duration on clinical outcomes of patients with GG 4 and GG 5 PCa, we performed an individual patient-level meta-analysis of six randomized trials. Our working hypothesis was that longer durations of ADT would offer significant survival benefits in both groups. (more…)

MedicalResearch.com Interview with: “Actinic Keratosis” by Ed Uthman is licensed under CC BY 2.0Howa Yeung, MD Assistant Professor of Dermatology Emory University School of Medicine Atlanta, GA 30322  MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by actinic keratoses? Response: Actinic keratoses are common precancerous skin lesions caused by sun exposure. Because actinic keratoses may develop into skin cancers such as squamous cell carcinoma and basal cell carcinoma, they are often treated by various destructive methods. We used Medicare Part B billing claims to estimate the number and cost of treated actinic keratoses from 2007 to 2015. MedicalResearch.com: What are the main findings?  Response: While the number of Medicare Part B beneficiaries increased only moderately, the number of actinic keratoses treated by destruction rose from 29.7 million in 2007 to 35.6 million in 2015. Medicare paid an average annual amount of $413.1 million for actinic keratosis destruction from 2007 to 2015. Independently billing non-physician clinicians, including advanced practice registered nurses and physician assistants, are treating an increasing proportion of actinic keratosis, peaking at 13.5% in 2015. MedicalResearch.com: What should readers take away from your report? Response: Readers should understand that the burden of actinic keratosis treatment is increasing in the Medicare population. There is also an increasing proportion of actinic keratoses being treated by advanced practice registered nurses and physician assistants.  (more…)
Author Interviews, Diabetes, Gluten, Lancet, OBGYNE, Pediatrics / 21.09.2018

MedicalResearch.com Interview with: Knud Josefsen, senior researcher Bartholin Institute, Rigshospitalet, Copenhagen K, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: In a large population of pregnant women, we found that the risk of the offspring being diagnosed with type 1 diabetes before the age of 15.6 years (the follow up period) was doubled in the group of women ingesting the highest amounts of gluten (20-66 g/day) versus the group of women ingesting the lowest amounts of gluten (0-7 g/day). For every additional 10 grams of gluten ingested, the risk for type 1 diabetes in the child increased by a factor of 1.31. It the sense that it was a hypothesis that we specifically tested, we were not surprised. We had seen in animal experiments that a gluten-free diet during pregnancy protected the offspring from diabetes, and we wanted to see if we could prove the same pattern in humans. There could be many reasons why we would not be able to show the association, even if it was there (sample size, low quality data, covariates we could not correct for and so on), but we were off course pleasantly surprised that we found the association that we were looking for, in particular because it is quite robust (more…)
Author Interviews, Environmental Risks, Microbiome, Pediatrics, Weight Research / 20.09.2018

MedicalResearch.com Interview with: Anita Kozyrskyj PhD Professor in Pediatrics Faculty of Medicine & Dentistry School of Public Health University of Alberta MedicalResearch.com: What is the background for this study? Response: Data for this study were collected in the Canadian Healthy Infant Longitudinal Development (CHILD) cohort of over 3,500 full-term infants born between 2009 and 2012. When infants were 3-4 months of age, parents provided a sample of their poop. At that time, parents checked-off responses to questions about their home, including type and frequency of cleaning product use. The infant poop was initially frozen, then thawed later to extract DNA from the sample and identify microbes on the basis of their DNA sequence.  (more…)
Author Interviews, Diabetes, Heart Disease, JAMA, Lipids / 20.09.2018

MedicalResearch.com Interview with: Luca A. Lotta, MD, PhD Senior Clinical Investigator MRC Epidemiology Unit University of Cambridge MedicalResearch.com: What is the background for this study? What are the main findings?
  • Drugs that enhance the breakdown of circulating triglycerides by activating lipoprotein lipase (LPL) are in pre-clinical or early-clinical development.
  • It is not known if these drugs will reduce heart attacks or diabetes risk when added to the current first line therapies (statins and other cholesterol-lowering agents).
  • Studying this would require large randomised controlled trials, which are expensive (millions of GBPs) and time-consuming (years).
  • Human genetic data can be used to provide supportive evidence of whether this therapy is likely to be effective by “simulating” a randomised controlled trial.
  • Our study used naturally occurring genetic variants in the general population (study of ~400,000 people) to address this.
  • Individuals with naturally-lower cholesterol due to their genetic makeup were used as model for cholesterol-lowering therapies (eg. Statins).
  • Individuals with naturally-lower triglycerides due to genetic variants in the LPL gene were used as model for these new triglyceride-lowering therapies.
  • We studied the risk of heart attacks and type 2 diabetes in people in different groups.

Asthma, AstraZeneca, Author Interviews, Pulmonary Disease / 20.09.2018

MedicalResearch.com Interview with: Tosh Butt, MBA VP Respiratory AstraZeneca MedicalResearch.com: What is the background for this study? How is benralizumab different from more traditional treatments for asthma?
    • BORA is a randomized, double-blind, parallel-group, Phase III extension, and is one of six Phase III trials in the WINDWARD program in asthma. The current analysis includes results for 1,926 patients from the two placebo controlled exacerbation trials, SIROCCO (48 week) and CALIMA (56 weeks). BORA provides evidence that add on maintenance treatment with FASENRA (benralizumab) resulted in a consistent safety profile over a second year of treatment, with no increase in the frequencies of overall or serious adverse events, and sustained efficacy in terms of reducing asthma exacerbations, and improving lung function and asthma symptoms. The BORA trial results could provide confidence to patients with severe eosinophilic asthma and physicians that the positive outcomes they may be seeing with benralizumab can be maintained over a second year of treatment.
  • FASENRA, a different kind of respiratory biologic, has a strong clinical profile which includes the ability to show lung function improvement after the first dose, the potential to reduce – or even stop - oral steroid use, and the convenience of 8-week dosing (no other respiratory biologic offers this dosing). FASENRA is approved for add-on maintenance treatment of patients with severe asthma ages 12 years and older, and with an eosinophilic phenotype. FASENRA binds directly to the IL-5a receptor on an eosinophil and uniquely attracts natural killer cells to induce apoptosis, or cell death. Other biologics currently available are anti-IL5s – a passive approach that primarily acts to block differentiation and survival of the eosinophil.

Author Interviews, OBGYNE, Pediatrics / 20.09.2018

MedicalResearch.com Interview with: Vida Maralani PhD Associate Professor Department of Sociology Cornell University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Breastfeeding is a time-intensive and culturally and emotionally charged topic in the U.S. with many different stakeholders. Women hear the strong message that they should breastfeed their infants for the first year of life, yet it is unambiguously clear that they find these guidelines hard to follow in practice. We were interested in exploring how breastfeeding duration is associated with how many children women go on to have. Our results show that women who breastfeed their first child for five months or longer are more likely to have three or more children, and less likely to have only one child, than women who breastfeed for shorter durations or not at all. Women who initiate breastfeeding did not differ in how many children they expected to have before they started their families. Rather, the number of children women actually bear differs by how long they breastfeed their first child. Women who breastfeed for shorter durations are more likely to have fewer children than they expected than to have more children than expected. In contrast, women who breastfeed longer are as likely to achieve their expectations as to exceed them, and they are nearly as likely to have more children than they expected as they are to have fewer.

Alzheimer's - Dementia, Author Interviews / 20.09.2018

MedicalResearch.com Interview with: Dr Christina Elliott PhD Postdoctoral Researcher Department of Old Age Psychiatry King’s College London MedicalResearch.com: What is the background for this study? Response: Amyloid-beta (Aβ) and its precursor protein, APP have been long implicated in pathogenesis of Alzheimer’s Disease but how they contribute to disease is not fully understood.  This has been further compounded by numerous failed clinical trials which attempted to target Aβ therapeutically. In Alzheimer’s Disease there is an overproduction of Aβ, which can disrupt how neurons communicate at structures called synapses.  It is thought that progressive synapse loss underpins cognitive impairments commonly seen in Alzheimer Disease patients such as memory loss. Our previous work highlighted a central role of the signalling pathway Wnt signalling in Aβ mediated synapse loss through the induction of dickkopf-1 (Dkk1), a well-known modulator of Wnt signalling. The aim of this study was to further investigate the molecular mechanisms of Aβ mediated synapse loss and explore whether this is connected to the overproduction of Aβ.  By dissecting out the key signalling events involved we hoped this would allow us to identify drugs which could be putative therapeutics for Alzheimer’ Disease.   (more…)
Author Interviews, Cannabis, Pain Research / 20.09.2018

MedicalResearch.com Interview with: “Cannabis” by Don Goofy is licensed under CC BY 2.0Martin De Vita, MS Doctoral Candidate Clinical Psychology Department Syracuse University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Despite widely held beliefs that cannabis is effective for pain relief, experimental trials have produced mixed results. As result, the analgesic properties of cannabinoid drugs have remained poorly understood. We aimed to clarify these findings by extracting data from every available experimental pain study and analyzing the results as a whole. We found that numerous aspects of pain were being influenced in different ways. We found that cannabinoid drugs did not significantly reduce the intensity of experimental pain, but they did produce small-sized reductions in pain unpleasantness. Cannabinoids produced significant analgesic effects on pain threshold and tolerance. There was no significant effect of cannabinoids on mechanical hyperalgesia. (more…)
Author Interviews, JAMA, USPSTF, Weight Research / 20.09.2018

MedicalResearch.com Interview with: Chyke Doubeni, M.D., M.P.H. Harrison McCrea Dickson, M.D. and Clifford C. Baker, M.D. Presidential Professor Associate Professor of Epidemiology Senior scholar, Center for Clinical Epidemiology and Biostatistics University of Pennsylvania School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Obesity is an important public health issue that affects nearly 4 in 10 American adults. It increases the risk for many chronic health conditions as well as premature death from diabetes, coronary heart disease, various types of cancer, and other conditions. As such, it was important for the U.S. Preventive Services Task Force to review the current evidence and update the recommendation on this topic. Based on a review of the most recent studies, we found that intensive, multicomponent behavioral interventions are safe and effective. They can help people lose weight, maintain their weight loss, and reduce the risk of obesity-related conditions such as diabetes in people with high blood sugar. Therefore, the Task Force is recommending that clinicians offer or refer adults with a body mass index, or BMI, of 30 kg/m2 or higher to these behavioral interventions.    (more…)

Cassimiro "Aranha" is licensed under CC BY 2.0Professor Phyo Kyaw Myint MBBS MD FRCP(Edin) FRCP(Lond) Clinical Chair in Medicine of Old Age Academic Lead: Ageing Clinical & Experimental Research & Director of Clinical Academic Training Development The Lead Academic, Aberdeen Clinical Academic Training (ACAT) Programmes School of Medicine, Medical Sciences & Nutrition College of Life Sciences & Medicine, University of Aberdeen MedicalResearch.com: What is the background for this study? What are the main findings? Response: While Mediterranean Diet has been linked to reduced stroke risk it remains unclear (1) its impact on populations within non-Mediterranean countries; (2) its specific impact on different gender; (3) the effect observed when using more robust dietary assessments; and (4) which specific components of the diet are most protective. We therefore studied more than 23 thousand men and women (mainly British Caucasian) aged 40 years or older in Norfolk, UK as part of EPIC-Norfolk study and we found that the greater adherence to Mediterranean dietary pattern is linked to a significant reduction in stroke risk in women but not in men. This benefit was seen across the whole middle and older age population (particularly for women) regardless of their existing risk factors such as high blood pressure. (more…)
Alzheimer's - Dementia, Author Interviews, CT Scanning, JAMA, Medical Imaging / 20.09.2018

MedicalResearch.com Interview with: PET scanner Wikipedia imageRik Ossenkoppele -PhD Lund University & VU University Medical Center Oskar Hansson - Lund University MedicalResearch.com: What is the background for this study? What are the main findings? Response: [18F]flortaucipir is a relatively novel PET tracer that can be used to detect tau pathology in the living human brain. Previous studies have shown a robust signal in patients with Alzheimer’s disease, but in patients with other types of dementia the signal was more variable. We aimed to assess the ability of [18F]flortaucipir PET to distinguish Alzheimer’s disease from other neurodegenerative disease in more than 700 study participants. T he main finding was that [18F]flortaucipir discriminated Alzheimer’s disease patients from patients with other neurodegenerative diseases with high accuracy. Furthermore, [18F]flortaucipir PET outperformed established MRI markers and showed higher specificity than amyloid-β PET.  (more…)
Allergies, Author Interviews, OBGYNE / 20.09.2018

MedicalResearch.com Interview with: “Pollen” by John S. Quarterman is licensed under CC BY 2.0Bircan Erbas, Associate Professor Reader/Associate Professor, Department of Public Health School of Psychology & Public Health La Trobe University  MedicalResearch.com: What is the background for this study? Response: Around the world allergic respiratory diseases especially in children is a major problem. Studies have already shown that cord blood IgE can be used to identify children at risk for allergic diseases. Our previous research showed that exposure to high levels of outdoor pollen, especially grass, in the first couple of months after birth increased risk of allergic respiratory diseases. Based on this, we suspected that exposure to high grass pollen during pregnancy could be also important. (more…)

MedicalResearch.com Interview with: Professor David Taylor Trinity Centre for Bioengineering Trinity College Dublin The University of Dublin, Ireland MedicalResearch.com: What is the background for this study? Response: The study was motivated by the emerging clinical problem of the failure of surgical mesh products used for transvaginal operations. Increasing numbers of women are experiencing the failure of mesh used to treated vaginal prolapse, urinary incontinence and other pelvic organ conditions. I carried out a survey of all existing research, including medical case reports, meta studies of clinical outcomes and biomechanics research on the material, which is a knitted plastic mesh. A phenomenon known as "mesh erosion" causes damage to surrounding tissues and organs and can leave the person in severe and lasting pain.  (more…)

MedicalResearch.com Interview with: photostimulation of hair growthHan Eol Lee Ph.D. Flexible and Nanobio Device Lab. Department of Materials Science and Engineering KAIST MedicalResearch.com: What is the background for this study? Response: Numerous people around the world have suffered from alopecia, which leads to aesthetic issues, low self-esteem, and social anxiety. With the population expansion alopecia patients from middle-age down even to the twenties, a depilation treatment is expected to have social and medical impacts on billions of patients. The causes of alopecia are generally known to be heredity, mental stress, aging, and elevated male hormone. Therapeutic techniques such as thermal, electrical, pharmacological, and optical stimulation have been proposed to treat hair problems. Among them, laser stimulation to hair-lost regions is a promising technique, activating the anagen phase and the proliferation of hair follicles without side effects. However, this laser stimulation technique has drawbacks, such as high power consumption, large size, and restrictive use in daily life (e.g., the difficulty of microscale spatial control and the long time exposure of high-energy laser).  (more…)

MedicalResearch.com Interview with: Richard B. Cannon, MD Division of Otolaryngology–Head and Neck Surgery School of Medicine University of Utah, Salt Lake City  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The Patient Protection and Affordable Care Act (ACA) is a nationwide effort to reduce the number of uninsured individuals in the United States and increase access to health care. This legislation is commonly debated and objective data is needed to evaluate its impact.  As a head and neck cancer surgeon, I sought to evaluate how the ACA had specifically influenced my patients.  Main findings below:     MedicalResearch.com: What should readers take away from your report? Response: This population-based study found an increase in the percentage of patients enrolled in Medicaid and private insurance and a large decrease in the rates of uninsured patients after implementation of the Patient Protection and Affordable Care Act (ACA).  This change was only seen in states that adopted the Medicaid expansion in 2014. The decrease in the rate of uninsured patients was significant, 6.2% before versus 3.0% after. Patients who were uninsured prior to the Patient Protection and Affordable Care Act had poorer survival outcomes. (more…)
Author Interviews, Exercise - Fitness, Lifestyle & Health / 18.09.2018

MedicalResearch.com Interview with: “sleeping” by Venturist is licensed under CC BY 2.0Matthieu Boisgontier  PhD Movement Control & Neuroplasticity Research Group KU Leuven Brain Behaviour Laboratory University of British Columbia, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: For decades, society has encouraged people to be more physically active. Yet, despite gradually scaling up actions promoting physical activity across the years, we are actually becoming less active. From 2010 to 2016, the number of inactive adults has increased by 5% worldwide, now affecting more than 1 in 4 adults (1.4 billion people). This context raised the question: Why do we still fail to be more physically active? Our hypothesis was that this failure is explained by an “exercise paradox” in which conscious and automatic processes in the brain come into conflict. To illustrate this paradox, you can think of people taking the elevator or escalator when they go to the gym, which does not make sense. This non-sense, this paradox, could be due to the fact that their intention to exercise come into conflict with an automatic attraction to resting in the elevator. (more…)

Accidents & Violence, Author Interviews, JAMA, Pediatrics / 18.09.2018

MedicalResearch.com Interview with: Dr Ruth Blackburn PhD  UKRI Innovation Fellow UCL Institute of Health Informatics Dr Ruth Blackburn PhD  UKRI Innovation Fellow UCL Institute of Health Informatics  MedicalResearch.com: What is the background for this study? What are the main findings? Response: In England one child in every classroom is admitted to hospital with an adversity related injury (i.e. violence, intentional self-injury, or drug or alcohol misuse) between the ages of 10 and 19 years. These young people are more likely than their classmates to be re-admitted to hospital or to die within 10 years. We investigated how the rate of hospital admissions with an adversity related injury has changed over time among young people aged 10-24 years, using administrative data for National Health Service hospitals in England. We found that between 2012 and 2016, rates of admission with an adversity related injury (including intentional self-injury) increased steeply for girls, with the biggest increase (6% per year) among 15-19 year olds. During the same time period, rates of admission with an adversity related injury decreased in boys aged 15-24 years (4-5% per year) but increased slightly for 10-14 year olds (3% per year).  (more…)
Author Interviews, Cannabis, Neurology, University Texas / 17.09.2018

MedicalResearch.com Interview with: Dr. Francesca M. Filbey PhD Professor Program Head, Cognition and Neuroscience PhD Bert Moore Chair in BrainHealth UT Dallas MedicalResearch.com: What is the background for this study? What are the main findings? Response: The cannabis literature has generally focused on changes in brain function when engaged in a task. We were interested in examining whether these differences are present when not engaged in a task (i.e., during resting state) to understand baseline functional organization of the brain. Changes to baseline functional organization may reflect changes in brain networks underlying cognition. We also wanted to investigate whether specific brain waves, as measured by electroencephalography (EEG), are associated with measures of cannabis use, such as craving. (more…)
