Portland, Oregon 97239
Medical Research: What is the background for this study? What are the main findings?
Dr. Prasad: We wanted to get some information about when and which cancer drugs were called "game changer" or "breakthrough" or "revolutionary". What we found was surprising. The use of these grandiose terms, or superlatives, was common in news articles. They occurred across many classes of medication, were used for approved and unapproved drugs, and some of the use was questionable.
29 Oct Diabetes Raises the Risk of Surgical Infections
MedicalResearch.com Interview with:
Emily Toth Martin, Ph.D. MPH
Assistant Professor, Epidemiology
University of Michigan School of Public Health
Medical Research: What is the background for this study? What are the main findings?
Response: Surgical site infections are responsible for billions in health care costs in the U.S. We are working to identify groups of people who are particularly impacted by surgical site infections. By looking at the results of 94 studies, we were able to take a 60,000 foot view of the connection between diabetes and surgical site infection. We found that diabetes raises the risk of infection across many types of surgeries.

New York, NY
Medical Research: Why is it so important to understand the financial burdens families may face in providing end-of-life care for a loved one and why do you think the burdens may be greater for dementia than for other medical conditions?
Dr. Kelley: Understanding the financial risks that older adults face in the last years of life is important for individuals and families, in order to plan and save, if possible. It is also important for our policy makers, in particular, to know about these costs so that this information can help shape health and social policy that will best serve our society. Households of those with dementia face the greatest burden of costs, on average, particularly with regard to out-of-pocket expenses and the costs of caregiving. Many costs related to daily care for patients with dementia are not covered by health insurance, and these care needs, including everything from supervision, to bathing and feeding, may span several years.
28 Oct Improving Diabetes Control Means Decreasing Mortality
MedicalResearch.com Interview with:
Marcus Lind, M.D., Ph.D
Department of Medicine, Uddevalla Hospital
Uddevalla, Swede
Medical Research: What is the background for this study?
Dr. Lind: One of the main goals of the diabetes care is to reduce excess mortality in individuals with type 2 diabetes close to that of the general population. We want patients to have a similar life expectancy as individuals in the general population. Earlier studies have shown that targeting good glucose levels, blood lipid and blood pressure levels are beneficial with respect to decrease cardiovascular disease being the main cause for mortality. We wanted to evaluate the prognosis for individuals with type 2 diabetes today in Sweden.
Further, earlier population-based studies have generally assessed mortality rates only on a group level whereas we believe the prognosis differs greatly depending on various factors such as how well risk factor control is obtained in clinical practice. The Swedish Diabetes Registry include more than 90% of all individuals with type 2 diabetes in Sweden and information of e.g. the glycaemic control, measured by a biomarker called A1c exists for most persons. There were 97% who had at least 1 measurement. Also most patients had information of other risk factors, among others renal complications which we believed were of special concern.

MedicalResearch.com Interview with:
Heather Fay, MHS

Newton, MA
Medical Research: What is the background for this study? What are the main findings?
Response: This study was conducted by FCD Prevention Works, an international non-profit focused on school-based, substance abuse prevention. Using FCD’s database of over 50,000 6th-12th grade student survey responses, we sought to explore the relationship between parental permission of student substance use and negative consequences related to substance use.
We compared student alcohol and other drug use in the home, with or without a parent’s knowledge, to students’ self-reported negative consequences related to their own alcohol use. As might be expected, students who used alcohol or other drugs at home without their parents knowing were more likely to report negative consequences in the past 12 months related to their alcohol own use. Students who used at home with their parents knowing were protected against some negative consequences. These students were less likely than students who did not report this behavior to feel guilty about their drinking or regret something they did while drinking. However, these same students were at an increased risk of experiencing negative consequences related to addiction. These consequences included those which are indicative of a mounting dependency on alcohol, such as needing a drink or other drug first thing in the morning, using alcohol or other drugs alone, passing out because of drinking, and getting hurt or injured as a direct result of their alcohol use.
28 Oct Young Girls Abuse Alcohol More With Lack of Parental Supervision
MedicalResearch.com Interview with: Daniel J. Dickson, M.A. Graduate Student and Brett Laursen PhD Department of Psychology Florida Atlantic University Medical Research: What is the background for this study? What are the main findings? Response: With age, adolescents spend more time with peers, and engage in drinking behaviors at increasing levels. In particular, girls who reach puberty at earlier ages than their peers are at higher risk for abusing alcohol. This may be because early maturing girls seek out the company of older more mature peers, who have greater access to alcohol and (in the case of those prone to delinquency) may be more welcoming to younger girls who are having difficulties with agemates. Our study investigates the association between changes in parental autonomy granting and girls’ alcohol abuse over a three year period (ages 13-16), as a function of timing of pubertal maturation.28 Oct Genetic Variants on Chromosome 6 Reflect Different Immune Responses To Infections

Christian Hammer, PhD
École Polytechnique

Clinical Neuroscience
Max Planck Institute of Experimental Medicine
Göttingen, Germany
Medical Research: What is the background for this study? What are the main findings?
Dr. Hammer: The immune response after viral infection or vaccination varies considerably from person to person, which is important because these differences can account for clinical outcome or vaccine effectiveness. It has been shown before that part of this variability is heritable, indicating the possibility that differences in our genes might be involved. To test this, we performed a genome-wide association study in more than 2,300 individuals, using high-performance computing to analyze whether differences in the abundance of antibodies against 14 common viruses are caused by variable sites in our genome. We looked at about 6 million of these variants and found that a region on chromosome 6 that harbors many genes involved in immune regulation showed highly significant associations with immune response to influenza A virus, Epstein-Barr virus (EBV), JC polyomavirus, and Merkel Cell polyomavirus. The genetic variants result in structural differences in proteins whose job it is to present fragments of pathogens that have been taken up by cells to the immune system. Interestingly, a given variant can lead to an increased immune response to one virus, e.g. influenza A, and at the same time to a decreased immune response to another, e.g. EBV, which is likely due to an altered ability of the protein to bind and present specific viruses, depending on the genetic background.
28 Oct Breastfeeding May Have Protective Effect Against Triple Negative Breast Cancer

Medical Research: What is the background for this study?
Dr. Boffetta: Evidence of a protective effect of breastfeeding on breast cancer risk is becoming stronger; hence the need for a systematic review and meta-analysis.
Medical Research: What are the main findings?
Dr. Boffetta: Breastfeeding appears to be protective against breast cancer, in particular the most aggressive forms (hormone receptor negative and in particular ‘triple negative’).
28 Oct FDA Approves Belbuca Opioid Delivery Film For Chronic Severe Pain

Dr. Richard Rauck[/caption]
MedicalResearch.com Interview with:
Richard L. Rauck, M.D.
Director of Carolinas Pain Institute
Winston Salem, NC
Medical Research: How large is the problem of chronic pain severe enough to require daily, around-the-clock, long-term opioid treatment and for whom alternative treatment options are inadequate?
Dr. Rauck: Chronic pain affects more than 100 million Americans - more than diabetes, heart disease and cancer combined. It is the most common cause of long-term disability, costing the U.S. billions of dollars annually in medical costs and lost wages and productivity.
Medical Research: What are the main medical conditions associated with this type of pain?
Dr. Rauck: A National Institute of Health Statistics survey indicated that low back pain is the most common cause of chronic pain (27%), followed by severe headache or migraine pain (15%), neck pain (15%) and facial ache or pain (4%).
28 Oct Surgical Experience Improved With Patient Text Alerts and Web App

Dr. Carmine Simone MD, FRCSC
Chief, Department of Surgery, Toronto East General Hospital
Co-Program Medical Director, Surgery HealthService, Toronto East General Hospital
Lecturer, University of Toronto, Division of Thoracic Surgery
Courtesy Staff, Sunnybrook Health Sciences Centre & Royal Victoria Hospital, Barrie
Medical Research: What is the background for this study? What are the main findings?
Dr. Simone: Patients preparing for surgery are often overwhelmed with information. Most of the time patients are given written instructions regarding preoperative preparation as well as written information at discharge. Our own institutional experience is that only 2/3 of patients read the information we provide and less than half of these patients can understand or retain the information they read.
We have found that providing patients SMS alerts or reminders leading up to their surgery increases the likelihood that they will follow instructions and keep their appointments. Furthermore having patients log their progress after discharged from hospital allows patients to track their progress and report complications earlier and avoid coming to the ER. Educational modules enable patients to better gauge their symptoms and make more informed decisions about calling the surgeon’s office or proceeding to the emergency department. We found a significant reduction in the number of ER visits and cancelled procedures after implementing the mobile device reminders and post-discharge daily log.

28 Oct Young Adults Who Eat Lots Fruits & Vegetables Lower Risk Of Coronary Artery Calcium
[caption id="attachment_18607" align="alignleft" width="150"]
Dr. Michael Miedema[/caption]
MedicalResearch.com Interview with:
Michael D. Miedema, MD, MPH
Minneapolis Heart Institute Foundation
Abbott Northwestern Hospital
Minneapolis, MN
Medical Research: What is the background for this study?
Dr. Miedema: A healthy diet is an essential component in the prevention of cardiovascular disease. A dietary pattern high in fruits and vegetables has been associated with reduced rates of cardiovascular disease outcomes in multiple observation cohorts of middle-aged and older adults. However, the cardiovascular impact of fruit and vegetable intake in younger adults is less clear.
Medical Research: What are the main findings?
Dr. Miedema: To evaluate this relationship, we studied 2,506 young adults in the Coronary Artery Risk Development in Young Adults (CARDIA) study to determine the association between fruit and vegetable intake during young adulthood and subsequent development of coronary artery calcium 20 years later. After adjusting for age, gender, and lifestyle variables, including smoking and physical activity, we found an inverse relationship between fruit and vegetable and subsequent coronary artery calcium across tertiles of fruit and vegetable intake (p-value <0.001). Individuals in the top third of fruit and vegetable intake at baseline had 26% lower odds of developing calcified plaque 20 years later. This inverse linear relationship remained significant after adjusting for fruit and vegetable intake at year 20 as well as after adjustment for other dietary variables such as dairy, nuts, fish, salt, and refined grains.
28 Oct Insulin Activity in Brain Influences What and When We Eat
[caption id="attachment_18828" align="alignleft" width="150"]
Dr. Margaret Rice[/caption]
MedicalResearch.com Interview with:
Dr. Margaret E. Rice, PhD
Professor, Department of Neuroscience and Physiology
Neurosurgery
NYU Langone Medical Center
Medical Research: What is the background for this study? What are the main findings?
Dr. Rice: Insulin is released from the pancreas into the bloodstream in response to a rise in circulating glucose levels when we eat. In most cells in the body, including those of liver and muscle, insulin acts at insulin receptors to promote glucose transport and other metabolic functions. Insulin also enters the brain and acts at brain insulin receptors, particularly in the hypothalamus where insulin acts as a satiety signal to indicate that we are full and should stop eating. The rising incidence of obesity, in which circulating insulin levels are chronically elevated, suggests insulin may play a role in other brain regions, as well, including regions that regulate motivation and reward.
Indeed, our new studies introduce a new role for insulin as a reward signal that acts in the dorsal striatum to enhance release of dopamine. Dopamine is a key neurotransmitter in reward systems; most drugs of abuse enhance release of dopamine, which contributes to their addictive properties. We found that insulin, at levels found in the brain by the end of a meal, enhances dopamine release by activating insulin receptors on acetylcholine-containing striatal cells that boost dopamine release. Consistent with a role of insulin in signaling reward, companion behavioral studies in rodents indicate that insulin signaling in the striatum communicates the reward value of an ingested meal, and thereby influences food choices. These studies reveal the dual nature of insulin in the brain, which not only tells us when to stop eating, but also influences what we eat.
27 Oct Improved Stem Cell Model Can Test Drugs For Kidney Toxicity
[caption id="attachment_18851" align="alignleft" width="100"]
Dr. Zink[/caption]
MedicalResearch.com Interview with:
Daniele Zink PhD
Institute of Bioengineering and Nanotechnology
Singapore
Medical Research: What is the background for this study?
Dr. Zink: The kidney is one of the main target organs for toxic effects of drugs, environmental toxicants and other compounds. Renal proximal tubular cells (PTCs) are frequently affected due to their roles in compound transport and metabolism. Validated and accepted assays for the prediction of PTC toxicity in humans currently do not exist. Recently, we have developed the first and only pre-validated assays for the accurate prediction of PTC toxicity in humans 1, 2. This previous work was performed with human primary renal proximal tubular cells (HPTCs) or embryonic stem cell-derived HPTC-like cells. HPTCs are associated with a variety of issues that apply to all kinds of primary cells, such as cell sourcing problems, inter-donor variability and limited proliferative capacity. Embryonic stem cell-derived cells are associated with ethical and legal issues. These are the main reasons why induced pluripotent stem cell (iPSC)-derived cells are currently a favored cell source for in vitro toxicology and other applications.
The problem was that stem cell-based approaches were not well-established with respect to the kidney. Recently, the group of IBN Executive Director Prof. Jackie Y. Ying developed the first protocol for differentiating embryonic stem cells into HPTC-like cells, and my group has contributed to characterizing these cells and publishing the results 3. In the work published in Scientific Reports ,4we have applied a modified version of this protocol to iPSCs. In this way, we have established the simplest and fastest protocol ever for differentiating iPSCs into HPTC-like cells. The cells can be used for downstream applications after just 8 days of differentiation. These cells can also be applied directly without further purification due to their high purity of > 90%.
By using these cells, we have developed the first and only iPSC-based model for the prediction of PTC toxicity in humans. This was achieved by combining our iPSC-based differentiation protocol with our previously developed assay based on interleukin (IL)6/IL8 induction 1, 2 and machine learning methods 5. Machine learning methods were used for data analysis and for determining the predictive performance of the assay. The test accuracy of the predictive iPSC-based model is 87%, and the assay is suitable for correctly identifying injury mechanisms and compound-induced cellular pathways.
26 Oct Medicaid Patients, Minorities Less Likely To Receive Regional Anesthesia

Dr. Jashvant Poeran[/caption]
MedicalResearch.com Interview with:
Jashvant Poeran MD PhD
Assistant Professor
Dept. of Population Health Science & Policy
Icahn School of Medicine at Mount Sinai
New York, NY
Medical Research: What is the background for this study?
Dr. Poeran: Neuraxial anesthesia and peripheral nerve blocks are two techniques for regional anesthesia for hip and knee replacements. Compared to general anesthesia, these two regional anesthesia techniques are increasingly seen as ‘higher quality care’ as a growing number of studies show that patients have better outcomes after surgery when regional anesthesia is used. However, less is known about the factors that influence the process of anesthetic care. This is important information because the choice for regional anesthesia might affect outcomes after hip and knee replacement surgery. We therefore used a large national database of health claims of hip and knee replacement procedures to study if specific patient subgroups were less likely to receive regional anesthesia.
26 Oct Outcomes of Shorter Radiation Therapy for Prostate Cancer Reported

MedicalResearch.com Interview with:
Luca Incrocci, MD, PhD

Erasmus MC-Daniel den Hoed Cancer
Rotterdam, The Netherlands
Medical Research: What is the background for this study? What are the main findings?
Dr.Incrocci: The trial was designed in 2005-2006. The rationale was to reduce the number of fractions and therefore increase patient's comfort. At that moment some preliminary data was available on the sensitivity of prostate cancer cells to a higher does per fraction.
Our calculations brought us to choose this new fractionation schedule.
The hypofractionation arm (19x3.4 Gy/3 times per week) has shown equivalence in outcome compared to the conventional treatment (39x2 Gy/5 times per week) at a follow-up of 5 yrs. Toxicity is comparable, with a slight increase in bowel complaints at 5yrs. Patients will be followed-up to 10yrs.
26 Oct NYU Plastic Surgeon Discusses Science and Art of Breast Reconstruction Surgery
MedicalResearch.com Interview with:
Mihye Choi, M.D., F.A.C.S.
Associate Professor of Surgery
NYU Plastic Surgery
NYU Langone Medical Center
Medical Research: Would you tell us a little about yourself and your interests in plastic surgery?
Dr. Choi: I wanted to be a surgeon first, then I fell in love with plastic surgery after seeing a cleft lip repair as a medical student. It was amazing to watch the ingenuity of the design and the skills needed to repair a baby's face. I felt that it was the highest gift a doctor can bestow, so that a child can go forward with life in confidence and all the promise that life holds. After finishing plastic surgery training, I developed expertise in breast reconstruction over the years. I feel breast reconstruction combines the science and art of surgery.
26 Oct High Pregnancy Weight Gain Linked To Long Term Increased Maternal Body Fat
MedicalResearch.com Interview with:
Elizabeth M. Widen, PhD, RD
Postdoctoral Fellow in the Department of Medicine, Institute of Human Nutrition & Department of Epidemiology
Columbia University
Mailman School of Public Health
New York, NY 10032
Medical Research: What is the background for this study? What are the main findings?
Dr. Widen: The Columbia Center for Children’s Environmental Health Mothers and Newborns Study was started in 1998 and is based in Northern Manhattan and the South Bronx. Pregnant African American and Dominican mothers were enrolled from 1998 to 2006, and mothers and their children have been followed since this time. Pregnancy weight gain and maternal size and body fat was measured at seven years postpartum, allowing us to examine the role of nutrition in pregnancy on long-term maternal health. We found that high pregnancy weight gain, above the Institute of Medicine 2009 guidelines, was associated with long-term weight retention and higher body fat at seven years postpartum among women who began pregnancy with underweight, normal weight and modest overweight body mass index (BMI). These findings suggest that prepregnancy BMI and high pregnancy weight gain have long-term implications for maternal weight-related health, especially among mothers who begin pregnancy with lower prepregnancy BMI values.

Joseph M Carrington DO, MHA
Department of Medicine - PGY3
Johns Hopkins University/Sinai Hospital
Medical Research: What is the background for this study? What are the main findings?
Dr. Carrington: This study looked at a total of 886 patients at a community hospital. We were faced with the dilemma that our ICU beds were frequently over utilized with severely ill patients for whom our interventions had minimal impact. This prevented patients who were less ill from coming to the ICU who may have benefited from our services. We made a hospital wide culture change to lower ICU admission thresholds. Any patient felt to be "borderline" received an automatic ICU evaluation without any push-back. The result of these earlier interventions was a decrease in complications from patients decompensating in the ED and floors. In turn, the overall ICU length of stay, mortality, and ICU transfers all decreased. By decreasing these overall complications and mortality, our number of ICU over-utilizes decreased. This saved our hospital an annualized amount of over $2 million and freed up ICU beds and resources.

Dr. Franco[/caption]
MedicalResearch.com Interview with:
Dr. Pablo Moreno Franco MD
Assistant Professor of Medicine
MAYO Clinic
Medical Research: What is the background for this study? What are the main findings?
Dr. Pablo Franco: Early alerts and prompt management of patient with severe sepsis and septic shock (SS/S) starting in the emergency department (ED) have been shown to improve mortality and other pertinent outcomes. With this in mind, we formed a multidisciplinary sepsis and shock response team (SSRT) in September 2013. Automated electronic sniffer alerted ED providers for possible sepsis and when S/SS was identified, they were encouraged to activate SSRT.
Two blinded reviewers retrospectively abstracted data on clinical trajectory and outcomes of all patients with sepsis and SS/S admitted at a single academic medical center between September 2013 and September 2014. Given importance of timely recognition and interventions in S/SS, we specifically focused on 2 periods: 0-4 hours and 4-12 hours after hospital admission. Additionally, we compared the compliance to “standard of care” between the SSRT pre-implementation period and the study period.
There were 167 patients admitted with sepsis, among which there were 3 SSRT activations and sepsis mortality was 3.6%. There were 176 patients with SS, SSRT was called in 42 (23%) and SS mortality was 8.5%. CCS was involved in 66 patients and mortality was 6.9% if SSRT was activated, versus 21.6% if SSRT was not activated. There were 76 patients with septic shock, SSRT was called in 44 (57%) and septic shock mortality was 25%. Critical Care Service (CCS) was involved in 68 patients and mortality rates with and without SSRT were 30.9% and 15.4%, respectively. The all-or-none compliance with applicable goals of resuscitation improved from the baseline 0% to over 50% at the study period end. Overall observed/expected sepsis mortality index improved from 1.38 pre-SSRT to 0.68 post-SSRT implementation.
26 Oct Baby Boomers Have More Chronic Conditions and Out-of-Pocket Medical Expenses
MedicalResearch.com Interview with: Sue Dong, DrPH Data Center Director CPWR-The Center for Construction Research and Training Silver Spring, MD, 20910 Medical Research: What is the background for this study? What are the main findings? Response: The Center for Construction Research and Training (CPWR) is a nonprofit organization funded by NIOSH and several other federal government agencies. The aging workforce study is part of our NIOSH projects. According to our surveillance data (using the Current Population Survey), more than 30% of US workers were baby boomers in 2014, and about 63% of those baby boomers were aged 55 and up. Overall, the baby boomer generation is composed of 75 million Americans who have reached or will soon reach their retirement years. Despite the impending magnitude of societal disruption, information on health status among baby boomers and the potential burden faced by this cohort is still scarce. We hope this study can provide some needed information on the aging population in the US. To address this concern, we used data from the Health and Retirement Study (HRS). HRS is a national longitudinal survey of Americans aged 50 and over, which started in 1992. The baby boomer cohort (including Early Baby Boomers and Mid Baby Boomers who were born between 1948 and 1959) was added to the survey in recent years. HRS collects information on demographics, employment, health, health expenditures, etc. The rich information and relatively consistent survey instruments used over time allowed us to conduct this study. Medical Research: What are the main findings? Response: We estimated medical conditions and expenditures among the baby boomer cohort and compared them with the original HRS cohort (born between 1931 and 1941). We found that the baby boomers were more likely to report chronic conditions than the previous generation (HRS cohort) at similar ages. For example, at age 51-61, about 70% of the baby boomer cohort had at least one chronic condition, while 60% of the HRS cohort had at least one chronic condition. By detailed condition, 42.2% of baby boomers had high blood pressure, compared to 32.1% of the HRS cohort; 14.4% of the baby boomers had diabetes, nearly twice the proportion for the HRS cohort (7.8%). Overall, baby boomers had higher prevalence of chronic conditions for the nine conditions we measured compared to the HRS cohort at the same age. We also found that the baby boomers were more likely to be overweight compared to the previous generation. The prevalence of obesity was 37% among baby boomers, but it was 21.9% among the HRS cohort when they were at similar ages In terms of medical expenditures, the average out-of-pocket expenditure (OOPE) for the past two years for those aged 51-61 was $2,156 for the HRS cohort, but $3,118 for the baby boomers. Dollar value was adjusted to 2012 dollars for even comparison. The findings will be presented at the recent APHA annual conference in Chicago.26 Oct Alcohol Linked To Increased Basal Cell Carcinoma Skin Cancer Risk

Boston, Massachusetts
Medical Research: What is the background for this study? What are the main findings?
Response: Basal cell carcinoma (BCC) of the skin is the most prevalent cancer in the US, and is responsible for substantial morbidity and billions of dollars of health care expenditures. Knowledge on the modifiable risk factors of BCC is required for targeted prevention of cancer incidence. Alcohol consumption is a well-known risk factor for human cancer and has been linked to a number of cancers, including breast, prostate, pancreatic, and colon cancers. Interestingly, a large epidemiological study has reported a positive association between alcohol consumption and increased prevalence of severe sunburn, an established skin cancer risk factor. It is hypothesized that metabolites of alcohol (e.g., acetaldehyde) can serve as photosensitizers and promote skin carcinogenicity in the presence of UV radiation. However, epidemiological evidence for the association between alcohol consumption and BCC risk has been limited and a few previous studies on this topic have yielded conflicting results. Therefore we conducted a comprehensive prospective study to investigate this question using data from three large cohorts including the Nurses’ Health Study (1984-2010), Nurses’ Health Study II (1989-2011), and Health Professionals Follow-up Study (1986-2010).
We documented a total of 28,951 incident Basal cell carcinoma cases over the study follow-up. We found that increasing alcohol intake was associated with an increased Basal cell carcinoma risk in both women and men. In the combined analysis with all 3 cohorts, those who consumed 30 grams or more alcohol per day had a 22% higher risk of developing BCC when compared to nondrinkers. This increased risk was consistent in people with different levels of sun exposure. We also found that BCC risk was associated with alcohol intake levels more than a decade ago, suggesting that alcohol may have a lagged effect that can persist for a long-term period. Among the individual alcoholic beverages, white wine and liquor were positively associated with Basal cell carcinoma risk whereas red wine and beer were not associated with BCC risk. This difference may be due to some other chemicals accompanying alcohol in the specific beverages. For example, red wine contains higher amounts of phenolic compounds compared to white wine, and these compounds have antioxidant activities which may be beneficial for counteracting the potential carcinogenic properties of alcohol and its metabolites.
26 Oct Breastfeeding May Not Protect Again Gluten Sensitive Celiac Disease
MedicalResearch.com Interview with: Maria Ines Pinto Sanchez, MD MSc Post-doctoral Clinical Research Fellow and Dr Elena Verdu, MD, PhD Farncombe Family Digestive Health Research Institute McMaster University Health Sciences Centre Hamilton, ON Medical Research: What is the background for this study? What are the main findings? Response: Celiac disease is a condition caused by ingestion of gluten in people with genetic predisposition, in which the finger like projections of the intestinal lining are damaged by inflammation. The “celiac” genes are necessary, but not sufficient, to develop celiac disease. For this reason, it is believed that additional factors could influence the risk of a predisposed child to develop celiac disease. Some studies have indeed suggested that the ideal time for the introduction of gluten to the diet would fall between the 4th and 6th month of life, when gluten should be introduced in “small quantities” and progressively, while maintaining breastfeeding whenever possible. The Nutrition Committee of the European Society of Paediatric Gastroenterology, Hepatology and Nutrition recommended avoiding the introduction of gluten before 4 months and after 7 months of age in an attempt to prevent celiac disease. However, not all clinical studies reached this conclusion and we therefore conducted an updated analysis of the literature published on this subject to evaluate the relationship between time and amount of gluten introduction, breastfeeding and the risk of developing celiac disease. Our systematic analysis revealed that based on the studies published to date there is no strong support that early gluten introduction to an infant’s diet increases the chances to develop celiac disease or that breastfeeding specifically protects from it.24 Oct Gene-edited Kidney Organoids Re-Create Human Disease

Medical Research: What is the background for this study? What are the main findings?
Dr. Freedman: We are born with a limited number of kidney tubular subunits called nephrons. There are many different types of kidney disease that affect different parts of the nephron. The common denominator between all of these diseases is the irreversible loss of nephrons, which causes chronic kidney disease in 730 million patients worldwide, and end stage renal disease in 2.5 million. Few treatments have been discovered that specifically treat kidney disease, and the therapeutic gold standards, dialysis and transplant, are of limited availability and efficacy.
Pluripotent stem cells are a renewable source of patient-specific human tissues for regeneration and disease analysis. In our study, we investigated the potential of pluripotent cells to re-create functional kidney tissue and disease in the lab. Pluripotent cells treated with a simple chemical cocktail matured into mini-kidney 'organoids' that closely resembled nephrons. Using an advanced gene editing technique called CRISPR, we created stem cells with genetic mutations linked to two common kidney diseases, polycystic kidney disease (PKD) and glomerulonephritis. Mini-kidneys derived from these genetically engineered cells showed specific 'symptoms' of these two different diseases in the petri dish.
24 Oct Acute Occupational Pesticide-Related Illness Highest in Agricultural Workers
MedicalResearch.com Interview with: Geoffrey M. Calvert MD Division of Surveillance, Hazard Evaluations, and Field Studies National Institute for Occupational Safety and Health CDC Cincinnati, Ohio Medical Research: What is the background for this study? Dr. Calvert: Since 1987, acute occupational pesticide-related illness and injury has been one of the conditions under surveillance by NIOSH. NIOSH supports these surveillance activities by providing cooperative agreement funding and technical support to state health departments. The SENSOR-Pesticides program is also partially funded by EPA. A total of 12 states currently participate in the SENSOR-Pesticides program. With the 2015 publication of the Summary of Notifiable Non-Infectious Conditions and Disease Outbreaks – United States, official statistics for the occurrence of acute occupational pesticide-related illness and injury were published for the first time in the same volume of the MMWR with information on nationally notifiable infectious diseases.

Matthew S. Thiese, PhD, MSPH
Assistant Professor
Rocky Mountain Center for Occupational and Environmental Health
University of Utah School of Medicine
Medical Research: What is the background for this study?
Dr. Thiese: The nearly 3 million truck drivers in the United States face many challenges including a lack of physical activity, limited healthy food choices, work-related stress, high physical job demands of loading and unloading trucks and a high risk of being involved in crashes. The purpose of the study was to describe truck driver health and assess relationships between both personal and occupational factors and risk of being involved in a crash. This is why it is important to get yourself checked out by a doctor before carrying out any activity involving being on the road. Depending on your job, you can be driving for a long period of time and it is most likely that you'll become tired. A tired driver being a wheel is at a high risk of being involved in an accident. If you are soon to visit your local doctor for any problems you may have, it may be good to look into something like jj keller eld reviews to give you another way of staying safe on the roads and to help you prevent any accidents that could occur. The main thing for anyone to do before driving is checking they are physically fit to get behind the wheel. The next step though is to make sure that you can actually drive a truck. There are loads of places that you can training from, for example, you could just check out a website like MyCDLTraining.com to help you learn how to drive a truck.
Medical Research: What are the main findings?
Dr. Thiese: There were many personal and occupational factors that were significantly related to being involved in a crash. Among the personal factors assessed, drivers were more likely to be involved in a crash if they used a cell phone regularly, drank alcohol regularly, had a prior diagnosis of heart problems, reported snoring at night, had low back pain in the past year and if they had a high pulse pressure, which is the difference between the systolic and diastolic measures and is indicative of cardiovascular disease. Occupational factors related to being involved in a crash included how long subjects had been a commercial truck driver and how physically exhausted they felt after work; drivers reporting higher physical exhaustion were more likely to be involved in a crash.

Medical Research: What is the background for this study? What are the main findings?
Dr. Kettunen: The initial discovery of the mortality biomarkers was made 1.5 years ago when we published the first paper describing four biomarkers indicative of 5-year mortality in two cohorts totaling over 17 000 population based samples (http://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1001606). We wanted to understand the molecular background of the strongest mortality predictor and this is how the current study was started. Here, The network was enriched with defense response genes and we had an idea to test if the biomarker was predictive of future severe infections. We were able to show that chronic inflammation creates extra stress to immune system and predisposes to future infections.

MedicalResearch.com Interview with:
Dr. Simple Singh MD
Epidemiologist
Division of Cancer Prevention and Control
CDC
Medical Research: What is the background for this study?
Dr. Singh: This report provides official federal statistics on the occurrence of cancer for 2011 and trends for 1999–2011 as reported by CDC and the National Cancer Institute (NCI). Cancer incidence data are from population-based cancer registries that participate in CDC’s National Program of Cancer Registries (NPCR) and NCI’s Surveillance, Epidemiology, and End Results (SEER) program reported as of November 2013. Cancer mortality data are from death certificate information reported to state vital statistics offices in 2013 and compiled into a national file for the entire United States by CDC’s National Center for Health Statistics’ (NCHS) National Vital Statistics System (NVSS). This report is a part of the first-ever Summary of Notifiable Noninfectious Conditions and Disease Outbreaks — United States, which encompasses various surveillance years but is being published in 2015.
Medical Research: What are the main findings?
Dr. Singh: In 2011, approximately 1.5 million invasive cancers were diagnosed in the United States, an annual incidence rate of 451 cases per 100,000 persons. In the same year, approximately 576,000 persons died of cancer nationally, an annual death rate of 169 deaths per 100,000 persons.
Cancer incidence and death rates increase with age.
Overall, 54% of cancer cases and 69% of cancer deaths in 2011 occurred among persons aged ≥65 years.
Among men in 2011, blacks had the highest cancer incidence and death rates in the United States, and American Indians/Alaska Natives and Asians/Pacific Islanders had the lowest cancer incidence and death rates.
Among women in 2011, whites had the highest cancer incidence rates and blacks had the highest cancer death rates. American Indians/ Alaska Natives had the lowest cancer incidence rates, and Asians/Pacific Islanders had the lowest cancer death rates.
By state, overall (all cancer sites combined) cancer incidence rates in 2011 ranged from 374 to 509 cases per 100,000 persons, and overall cancer death rates ranged from 126 to 201 deaths per 100,000 persons.
Four cancer sites accounted for half of all cases diagnosed in 2011, including 209,292 prostate cancers, 220,097 female breast cancers, 207,339 lung and bronchus cancers (110,322 among men and 97,017 among women), and 135,260 colon and rectum cancers (70,099 among men and 65,161 among women). These four sites also accounted for half of cancer deaths in 2011, including 156,953 lung cancer deaths, 51,783 colon and rectum cancer deaths, 40,931 female breast cancer deaths, and 27,970 prostate cancer deaths.
During 1999–2011, cancer incidence rates declined from 485 cancer cases per 100,000 population in 1999 to 444 cases in 2011. Although lung cancer incidence declined steadily among men from 1999 to 2011, it increased among women from 1999 to 2005 and has since declined from 2005 to 2011. Prostate cancer incidence declined from 170 cases per 100,000 men in 1999 to 128 cases in 2011. Colorectal cancer incidence declined from 57 cases per 100,000 persons in 1999 to 40 cases in 2011. Female breast cancer incidence declined from 135 cases per 100,000 women in 1999 to 121 cases in 2005, increased to 125 cases in 2009, and declined again to 122 cases in 2011. During 1999–2011, cancer death rates declined from 201 deaths per 100,000 persons in 1999 to 169 deaths in 2011; during the same period, death rates declined for each of the top four cancers.
