MedicalResearch.com Interview with: Dr. Yasser Iturria Medina PhD Post-doctoral fellow Montreal Neurological Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: We used over 200 peripheral molecular biomarkers, five different neuroimaging modalities and cognitive/clinical measurements to detect spatiotemporal abnormalities in subjects with dementia or with mild signs of cognitive deterioration. By means of a mathematical framework, we reordered all the biomarkers/descriptors considered, according to how much they change during the disease process. The results suggested that, contrary as suggested by more traditional clinical analyses, there are multiple early signs of neurodegeneration, at the molecular level and at the brain’s macroscopic and cognitive state. In particular, we observed notable early signs of generalized vascular dysregulation, which may be supporting the vascular hypothesis of Alzheimer’s disease. However, we still need to perform deeper analyzes, in order to clarify the complex causal mechanisms that trigger the disease. (more…)

MedicalResearch.com Interview with: Kejal Kantarci, M.D. M.S. Professor of Radiology Division of Neuroradiology MedicalResearch.com: What is the background for this study? What are the main findings? Response: A rapid decline in estrogen with menopause may be associated with an increased risk of Alzheimer’s disease risk in women. This study was conducted in newly postmenopausal women who received 17β-Estradiol via a skin patch or conjugated equine estrogen orally or placebo. Those who received 17β-Estradiol patch had reduced β-amyloid deposits, the plaques found in the brains of people with Alzheimer’s disease, three years after the end of the hormone therapies. In the study, women with APOE e4 — one form of the most common gene associated with late-onset Alzheimer's disease — who received the 17β-Estradiol patch had lower levels of β-amyloid deposits than those who received placebo.

MedicalResearch.com Interview with: Leigh Purvis, MPA Director of Health Services Research AARP Public Policy Institute Editors’ note: In conjunction with the AARP’s new investigative piece, 'Supplement Pills That Promise Too Much', Leigh Purvis, Director of the AARP Health Services Research program discussed the issue of the proliferation of supplements, often with labels that make extraordinary health benefit claims. MedicalResearch.com: How many Americans use nutritional supplements? How big is the business of supplements? Response: Supplements are very popular in the United States. This is particularly true for older adults. A recent study found that the proportion of older adults using supplements increased from 52 percent in 2005 to 64 percent in 2011, and the share using multiple supplements grew by nearly 50 percent. According to the National Institutes of Health, American spent an estimated $36.7 billion on dietary supplements in 2014. (more…)
Author Interviews, Compliance, Hospital Readmissions / 13.07.2016

MedicalResearch.com Interview with: Jennifer Polinski, Senior Director Enterprise Evaluation and Population Health Analytics CVS Health Woonsocket, Rhode Island MedicalResearch.com: What is the background for this study? Response: Unnecessary and often preventable hospital readmissions are a growing and costly issue. An estimated one in seven patients discharged from a hospital is readmitted within 30 days, and startlingly, readmissions are associated with more than $41 billion in additional health care costs per year. In addition, evidence suggests that approximately 66 percent of hospital readmissions are the result of adverse health events related to medication non-adherence. (more…)
Alzheimer's - Dementia, Author Interviews, Chemotherapy, Parkinson's / 13.07.2016

MedicalResearch.com Interview with: Charbel Moussa MD. PhD Assistant Professor of Neurology Director- Laboratory for Dementia and Parkinsonism Clinical Research Director- National Parkinson's Foundation Center for Excellence Translational Neurotherapeutics Program Department of Neurology Georgetown University Medical Center Washington DC. MedicalResearch.com: What is the background for this study? What are the main findings? Response: We conducted a pilot open label proof-of-concept study to evaluate the safety and tolerability of Nilotinib in participants with advanced Parkinson’s disease (PD) with dementia (PDD) or dementia with Lewy bodies (DLB). Our primary objective is to demonstrate that low oral daily doses of 150mg or 300mg Nilotinib (compared to 600-800mg in cancer) are safe and tolerated. Our secondary objectives are that Nilotinib will cross the blood brain barier and may inhibit cerebral spinal fluid Abl. Based on preclinical data we also hypothesized that Nilotinib will increase DA levels. Motor and cognitive functions were also measured as exploratory clinical outcomes. Other exploratory outcomes are that Nilotinib may alter PD-related CSF biomarkers DJ-1 and α-synuclein. As most participants in this study had dementia we also explored the effects of Nilotinib on Alzheimer's Disease-related CSF biomarkers, including Aβ40 and Aβ42, total tau and phosphorylated tau (p-tau).

MedicalResearch.com Interview with: Dr. Marcos Muñoz Jimenez University of Jaén MedicalResearch.com: What is the background for this study? What are the main findings? Response: Barefoot running has become very popular in recent years and remains a hotly debated topic among runners. The debate about the pros and cons of barefoot running is current. Many coaches consider barefoot training to have an effect on muscle strength and to be important for performance and for preventing injuries. The main objective of this study is to determine what changes in foot strike, inversion-eversion and foot rotation are produced after a 12-week programme of barefoot running with progressive volume at the end of the athletes daily training session. Our data support that a 12-week programme of barefoot running training, applied by progressively increasing the volume of barefoot running, causes significant changes to foot strike patterns with a tendency towards midfoot strike, regardless of running speed.

MedicalResearch.com Interview with: Jason Busse PhD Department of Anesthesia Department of Clinical Epidemiology & Biostatistics McMaster University Hamilton, ON MedicalResearch.com: What is the background for this study? What are the main findings? Response: Persistent pain after breast cancer surgery affects up to 60% of patients. Early identification of those at higher risk could help inform optimal management. We conducted a systematic review and meta-analysis of observational studies to explore factors associated with persistent pain among women who have undergone surgery for breast cancer. We found that development of persistent pain after breast cancer surgery was associated with younger age, radiotherapy, axillary lymph node dissection, greater acute postoperative pain and preoperative pain. Axillary lymph node dissection increases the absolute risk of persistent pain by 21%, and provides the only high yield target for a modifiable risk factor to prevent the development of persistent pain after breast cancer surgery.

Author Interviews, CT Scanning, Heart Disease / 13.07.2016

MedicalResearch.com Interview with: Dr Maksymilian P. Opolski Department of Interventional Cardiology and Angiology Institute of Cardiology Warsaw, Poland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Valvular heart disease (VHD) that requires surgery is increasingly encountered in industrialized countries. Of particular interest, the presence of concomitant coronary artery disease (CAD) in patients with VHD is related to worse clinical outcomes, and various clinical studies suggested that combined valve and bypass surgery reduces early and late mortality. Consequently, in the majority of such patients, pre-operative evaluation for coronary artery disease (CAD) with invasive coronary angiography is recommended. However, provided that most patients with valvular heart disease are found to have no significant coronary stenoses, coronary computed tomography angiography (coronary CTA) appears as an extremely appealing noninvasive alternative to invasive coronary angiography for exclusion of significant CAD. This is further justified when the risks of angiography outweigh its benefits (e.g. in cases of aortic dissection or aortic vegetation). (more…)
Author Interviews, Cancer Research, Diabetes / 13.07.2016

MedicalResearch.com Interview with: Iliana Lega, MD, FRCPC Assistant Professor Department of Medicine and a Clinician Scientist University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Response: Diabetes and cancer share a variety of risk factors that predispose individuals to both conditions. However the exact mechanism of this relationship is unclear. Our study examined differences in cancer diagnosis at different time points around a diagnosis of diabetes. We found two interesting trends. First, people with diabetes have the highest risk for cancer in the first 3 months following a diagnosis of diabetes. Second, we found that people with diabetes are also more likely to have had cancer even prior to being diagnosed with diabetes. (more…)
Author Interviews, Metabolic Syndrome / 12.07.2016

MedicalResearch.com Interview with: Ilaria Cavallari, MD Department of Cardiovascular Sciences University Campus Bio-Medico Roma, Italy MedicalResearch.com: What is the background for this study? Response: Obesity is a well-known risk factor for metabolic and cardiovascular disease (CVD). However, more than the amount of adipose tissue, its function plays important roles in the development of CVD. Distribution of adiposity, evaluated by measuring body circumferences, is related to adipose dysfunction. Wrist circumference has been recently associated with insulin-resistance and diabetes. Therefore, body circumferences, wrist circumference in particular, are candidate easy and fast markers of cardiovascular risk, beyond the classical body mass index (BMI). (more…)

MedicalResearch.com Interview with: Dejan R. Nonato, MD, PhD Institute of Tropical Pathology and Public Health School of Medicine Federal University of Goiás Goiânia, GO, Brazil MedicalResearch.com: What is the background for this study? Response: Human papillomavirus (HPV) and Chlamydia trachomatis (CT) share the same route of sexual transmission and possess similar risk factors, indicating that co-infection may act synergistically in the induction of epithelial cell abnormalities.

Author Interviews, MRI, Weight Research / 12.07.2016

MedicalResearch.com Interview with: Guido Camps, MSc PhD candidate Wageningen University and Research Centre The Netherlands Editor's note:  The researcher would like readers to be aware that this work is preliminary and has not yet been published in a peer-reviewed journal. MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background was that we wanted to study gastric distension with actual food. Because using different foods would also change the caloric content, we added water. We wanted to see if we could measure both the stomach and the brain, and what the added distension would feel like to the subjects and what brain effects we could see. (more…)
Author Interviews, Diabetes, PLoS, Race/Ethnic Diversity / 12.07.2016

MedicalResearch.com Interview with: Matthew James O'Brien MD Northwestern University Feinberg School of Medicine MedicalResearch.com: What is the background for this study? Response: In October 2015, the United States Preventive Services Task Force (USPSTF) released new diabetes screening guidelines. This government-supported expert group recommended screening asymptomatic adults who are 40-70 years old and overweight or obese for diabetes. Recent population trends show that racial/ethnic minorities develop diabetes at younger ages and lower weights than whites. Therefore, we sought to determine whether these screening criteria may fail to identify racial/ethnic minorities or other high-risk population subgroups. Our study population was 50,515 patients from federally-funded community health centers, which serve large numbers of minorities and socioeconomically disadvantaged individuals. (more…)

MedicalResearch.com Interview with: Dr Fraser W Gibb MBChB PhD FRCP Edin Consultant Physician / Honorary Clinical Senior Lecturer Edinburgh Centre for Endocrinology & DiabetesDr Fraser W Gibb MBChB PhD FRCP Edin Consultant Physician / Honorary Clinical Senior Lecturer Edinburgh Centre for Endocrinology & Diabetes MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know that diabetic ketoacidosis is associated with a low risk of death in those admitted to hospital but we did not know what the risk of death was in the months and years following discharge from hospital. We have found that recurrent DKA admissions (more than 5 in a lifetime) are associated with a greater than 1 in 5 risk of death in the following three years compared to a 1 in 20 risk for those with only a single DKA. Recurrent DKA is more common in younger, more socially disadvantaged people. (more…)
Author Interviews, Breast Cancer, Genetic Research / 12.07.2016

MedicalResearch.com Interview with: Ana I. Vazquez PhD Department of Epidemiology and Biostatistics Michigan State University East Lansing, Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Precise predictions of whether a tumor is likely to spread would help clinicians and patients choose the best course of treatment. But current methods fall short of the precision needed. We tested whether breast cancer survival predictions could be improved by profiling primary tumor samples with genomic technologies. We found that predictions based on clinical information, such as cancer stage and subtype, improve when they incorporate comprehensive data on which genes are active in tumor samples compared to non-cancerous tissues from the same patient. This is also true for genome-wide methylation data, which maps the parts of the DNA that carry molecular "tags" that influence gene activation. If developed for use in the clinic, our approach could spare some patients from unneeded chemotherapy. (more…)
Author Interviews, Heart Disease, Hospital Readmissions, JACC, NYU, Race/Ethnic Diversity / 12.07.2016

MedicalResearch.com Interview with: Matthew Durstenfeld MD Department of Medicine Saul Blecker, MD, MHS Department of Population Health and Department of Medicine New York University School of Medicine NYU Langone Medical Center New York, New York MedicalResearch.com: What is the background for this study? What are the main findings? Response: Racial and ethnic disparities continue to be a problem in cardiovascular disease outcomes. In heart failure, minority patients have more readmissions despite lower mortality after hospitalization for heart failure. Some authors have attributed these racial differences to differences in access to care, although this has never been proven. Our study examined patients hospitalized within the municipal hospital system in New York City to see whether racial and ethnic disparities in readmissions and mortality were present among a diverse population with similar access to care. We found that black and Asian patients had lower one-year mortality than white patients; concurrently black and Hispanic patients had higher rates of readmission. These disparities persisted even after accounting for demographic and clinical differences among racial and ethnic groups. (more…)

MedicalResearch.com Interview with: Hsin-Jen Chen, PhD MS Assistant Professor Institute of Public Health National Yang-Ming University Taipei City MedicalResearch.com: What is the background for this study? Response: The number of eating occasions may affect health. Laboratory experiments have been showing that splitting daily food consumption into more eating occasions could improve metabolic profiles, such as healthier blood glucose and lipids levels. However, such kinds of experiments usually design a highly controlled diet for the participants in the lab. It is questionable whether such metabolic benefits remain in our daily life (namely, no controlled diets) where we can eat at anytime when we want to eat. (more…)
Author Interviews, Infections / 12.07.2016

MedicalResearch.com Interview with: Jenny A. K. Ekberg Eskitis Institute for Drug Discovery Faculty of Health Sciences and Medicine, Bond University Institute for Health and Biomedical Innovation, Queensland University of Technology, School of Medical Science, Griffith University Queensland, Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Melioidosis is a tropical bacterial infection that causes around 90,000 deaths world-wide each year. It is caused by the bacteria Burkholderia pseudomallei which can cause pneumonia and a serious flu-like illness which can cause death, however if the brain is infected, which happens in particular with the Australian variant of the disease, the mortality is particularly high (~25 %). The route by which the bacteria invade and progress through the central nervous system is to date largely unknown. We have now shown in an animal model that the bacteria can penetrate the trigeminal nerve within the nasal cavity and then rapidly invade the brainstem and spinal cord only 24 hours after intranasal inoculation. By migrating along the trigeminal nerve, the bacteria bypasses the blood-brain barrier.This study constitutes the first characterization of the path by which B. pseudomallei bacteria migrate all the way from the nasal cavity into the spinal cord.

MedicalResearch.com Interview with:, Jun Wang, M.D., Ph.D. Assistant Professor Department of Neuroscience and Experimental Therapeutics Interdisciplinary Program in Neuroscience (TAMU/TAMHSC) TAMHSC COLLEGE OF MEDICINE Bryan, TX 77807 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Alcohol use disorder is a big problem for our society and only a limited number of medicine is available. We hope to find more treatment in animal models of alcoholism. A group of neurons containing dopamine D2 receptors in the brain prevent us from drinking alcohol heavily. (more…)
Author Interviews, Cancer Research, Cost of Health Care, Health Care Systems, JAMA / 11.07.2016

MedicalResearch.com Interview with: Laura B. Vater, MPH MD Candidate 2017 Indiana University School of Medicine MedicalResearch.com: What is the background for this study? Response: In the United States, cancer center advertisements are common. Previous research has shown that these ads use emotion-based techniques to influence viewers and omit information about benefits, risks, and costs of cancer treatment. There is a concern that cancer center advertising may increase demand for unnecessary tests and treatments, increase healthcare costs, and provide unrealistic expectations about the benefits of cancer treatment. In this study, we examined cancer center advertising spending from 2005 to 2014, with particular attention to trends within media (television networks, magazines, newspapers, radio stations, billboards, and the Internet) and by target audience (national versus local).

Author Interviews, Heart Disease, Lipids / 11.07.2016

MedicalResearch.com Interview with: Joost Besseling, PhD-student Academic Medical Center Dept. of Vascular Medicine Amsterdam MedicalResearch.com: What is the background for this study?  Response: It was unkown to what extent statin therapy reduces the risk for coronary artery disease and mortality in patients with heterozygous familial hypercholesterolemia (FH). One previous study found that the relative risk reduction was 76%, but the study population in this study consisted of with a very severe FH phenotype. This result is therefore an overestimation of the risk reduction in the general heterozygous familial hypercholesterolemia population. (more…)
Alzheimer's - Dementia, Author Interviews, Brain Injury, JAMA, Parkinson's / 11.07.2016

MedicalResearch.com Interview with: Paul K. Crane, MD MPH Professor Department of Medicine Adjunct Professor Department of Health Services University of Washington MedicalResearch.com: What is the background for this study? Response: The background is that the most common experience of head injury with loss of consciousness is an apparent recovery. Sometimes this is very fast, sometimes it takes somewhat longer, but typically people return to their prior baseline. Nevertheless there is concern that the head injury may have set in motion processes that would lead to late life neurodegenerative conditions. This is bad enough for someone to deal with but it's made even worse if the head injury isn't even the victim's fault. Previous research has focused especially on Alzheimer's disease. A more limited research has focused on Parkinson's disease. We used data from three prospective cohort studies that included more than 7,000 people to study the relationship between head injury with loss of consciousness and subsequent risk of Alzheimer's and Parkinson's disease. We collected head injury exposure data at study enrollment, at a time when we administered cognitive tests and knew they did not have dementia, so our exposure data are not biased. Each of these studies also performed brain autopsies on people who died, and we evaluated data from more than 1500 autopsies. (more…)
AHA Journals, Author Interviews, CDC, Heart Disease / 11.07.2016

MedicalResearch.com Interview with: Suzanne Meredith Gilboa, PhD Epidemiologist at the Centers for Disease Control and Prevention’s National Center on Birth Defects and Developmental Disabilities MedicalResearch.com: What is the background for this study? What are the main findings? Response: Because of advancements in care, there has been a decline in mortality from congenital heart defects (CHD) over the last several decades. However, there are no current empirical data documenting the number of people living with CHD in the United States (US). The purpose of this study was to estimate the  congenital heart defects prevalence across all age groups in the US for the year 2010. Using prevalence data from Québec, Canada in the year 2010 as a foundation for a mathematical model, we estimated that approximately 2.4 million people (1.4 million adults, 1 million children) were living with CHD in the US in the year 2010. Nearly 300,000 subjects had severe CHD. Overall, there was a slight predominance of females compared to males. (more…)
Author Interviews, Cancer Research, Stem Cells / 11.07.2016

MedicalResearch.com Interview with: Cédric Blanpain, MD, PhD Professor of Stem Cell and Developmental Biology WELBIO, Interdisciplinary Research Institute (IRIBHM) Université Libre de Bruxelles (ULB) Belgium MedicalResearch.com: What is the background for this study? Response: Many cancers arise from tissues maintained by stem and progenitor cells that ultimately give rise to non-dividing terminally differentiated cells. However, little is known about the contribution of stem cells and progenitors to cancer initiation. During tumor initiation, cells targeted by oncogenic mutations undergo a series of molecular changes leading to their clonal expansion and the acquisition of invasive properties. How exactly oncogenic mutations impact on the rate of stem cell and progenitor division, and change the proportion of divisions that result in symmetric and asymmetric cell fate, allowing clonal expansion and tumor progression is poorly understood. In this new study, we define for the first time the clonal dynamics that lead to skin cancer initiation using the basal cell carcinoma, the most frequent tumor in humans, as a model. (more…)
Author Interviews, Biomarkers, Colon Cancer, Science / 11.07.2016

MedicalResearch.com Interview with: Jeanne Tie MBChB, FRACP, MD Division of Systems Biology and Personalised Medicine, Walter and Eliza Hall Institute of Medical Research Department of Medical Oncology, Western Health, St Albans, Victoria, Australia. Department of Medical Oncology, Faculty of Medicine, Dentistry and Health Sciences, University of Melbourne Parkville, Victoria, Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study investigated the ability of circulating tumor DNA (ctDNA) in detecting residual microscopic cancer after surgery with curative intent in patients with stage II colon cancer. Although the majority of patients with stage II colon cancer are cured by surgery alone, our ability to accurately predict the risk of cancer relapse based on current clinical and pathological criteria is imprecise. Population-based study indicated that adjuvant chemotherapy is given to up to 40% of stage II colon cancer patients, meaning that we are over-treating a significant number of patients with cytotoxic therapy. A better indicator of residual disease and recurrence would be very useful clinically. The current study collected tumor and blood samples from 230 patients with stage II colorectal cancer. A personalised assay was then designed to detect patient-specific tumor DNA in the plasma samples collected four to ten weeks after surgery. The presence of ctDNA (positive test) in the post-operative blood sample predicted recurrence in 100% of patients, while the relapse rate is only 10% in those with negative ctDNA test. We have also shown that the ctDNA test is a better predictor of recurrence than the standard clinic-pathological criteria. (more…)

MedicalResearch.com: What is the background for this study? What are the main findings? Response: ACL re-tear after surgery is a serious complication in the sports medicine world with many implications for the athlete such as lost game time, the morbidity of a second surgery and extended rehabilitation, lost scholarship, decreased self esteem and social isolation,as well as decreased academic performance. We found in our study that athletes who are less than 25, are female, and have a graft size less than 8 mm are at increased risk for ACL re-tear after surgery. (more…)
Author Interviews, Cancer, Cancer Research, UCLA / 11.07.2016

MedicalResearch.com Interview with: Karim Chamie MD, MSHS Department of Urology Jonsson Comprehensive Cancer Center David Geffen School of Medicine University of California at Los Angeles Los Angeles, California MedicalResearch.com: What is the background for this study? Response: With improved cancer outcomes, there are 14 million cancer survivors alive in the United States in 2012. That number is expected to increase to nearly 20 million by 2024. With such a large population, many of these cancer survivors are at risk for developing a second primary malignancy. Multiple primary cancers now account for approximately 17% of all incident cancers reported each year in the United States. Cancer survivors may be especially susceptible to developing second primary malignancies due to a variety of unique factors, including genetic syndromes, common etiologic exposures, and the late effects of chemotherapy and radiotherapy. Given the longer duration of cancer survivorship and the substantial proportion of survivors at risk for developing second primary malignancies, the incidence and mortality from second primary malignancies are likely to increase.

Asthma, Author Interviews, Environmental Risks / 11.07.2016

MedicalResearch.com Interview with: Jamie T Mullins PhD Environmental Economics and Applied Microeconomic Department of Resource Economics University of Massachusetts Amherst Amherst, MA 01003 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Episodic triggers of asthma are widely known, but the root causes of the condition still aren’t well understood. There is also very limited evidence on the long-term impacts of exposure to air pollution. Speaking to both issues, we find evidence linking the development of asthma to exposure to a significant air pollution event early in life. The 1952 London Smog provides a natural experiment for studying the underlying cause of asthma and the long-term effects of air pollution exposure, while limiting threats from statistical confounding. The London Smog (also called the “Great Smog”) dramatically increased concentrations of air pollution across the city in December of 1952. We compare the incidence of asthma among those exposed to the Great Smog in utero or the first year of life to those in relevant comparison groups, including those conceived after the incident and those residing outside the affected area at the time of the Smog.

MedicalResearch.com Interview with: Hemilä Harri Hemilä, MD, PhD Department of Public Health, University of Helsinki MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our meta-analysis of 3 randomized controlled trials on zinc acetate lozenges was motivated by an early trial which indicated that zinc lozenges might be more effective for patients with allergies. We found that allergy, sex, age, and ethnic bacground did not influence the effect of zinc acetate lozenges. Thus, the average effect of 3 day reduction in colds seems to be applicable for a wide range of common cold patients. (more…)
Accidents & Violence, Author Interviews, Education, Geriatrics, Nursing / 10.07.2016

MedicalResearch.com Interview with: MedicalResearch.com: What is the background for this study? What are the main findings? Response: The impetus for this article was our experience from working at FAU’s Christine E. Lynn College of Nursing’s Louis and Anne Green Memory and Wellness Center with families as we conducted assessments of older adults referred to our program by family members or law enforcement. We realized that there is a need to educate nurses that a) they can help to identify persons who may be at risk for unsafe driving before accidents occur, and b) there are resources to help families and nurses navigate this challenging topic. This awareness is especially important for persons and friend/family members who find themselves trying to cope with a known or potential diagnosis of dementia. (more…)
