MedicalResearch.com Interview with: [caption id="attachment_48905" align="alignleft" width="199"]Dr Daniel Hwang PhDPostdoctoral Research FellowThe University of Queensland Diamantina Institute Dr. Hwang[/caption] Dr Daniel Hwang PhD Postdoctoral Research Fellow The University of Queensland Diamantina Institute MedicalResearch.com: What is the background for this study?   Response: The aim of the this study is to understand the genetic basis of human taste perception. In this international collaboration project, we started by collecting sensory data from twins in the Australia and USA since 2003. Based on the difference in the genetic relatedness between identical and non-identical twins, our previous studies have quantified the amount of genetic influence on sweet taste perception (https://doi.org/10.1017/thg.2015.42) as well as the other sensory phenotypes (https://doi.org/10.1093/chemse/bjs070). 
Author Interviews, Nutrition, Weight Research / 28.04.2019

MedicalResearch.com Interview with: Dale Morrison, PhD School of Exercise and Nutrition Sciences Institute for Physical Activity and Nutrition MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The study was conducted using a model of overfeeding that is likely to be representative of a typical Western overeating diet, high in both carbohydrates and fats; as opposed to a predominantly high-fat diet model that is commonly used in the literature. Our purpose was to examine which tissues are impaired first in response to overeating with a normal dietary composition. We initially hypothesized, based on earlier studies, that the liver would be impaired first by short-term overeating and then skeletal muscle (which soaks up much of the glucose following a meal) would be impaired much later with chronic overeating. However, we didn’t find this. The study found that the body copes with short periods of overeating with additional carbohydrates and makes adjustments by shifting metabolism towards utilizing these excess carbohydrates. 
Alcohol, Author Interviews, Hepatitis - Liver Disease, Lifestyle & Health, Sugar / 25.04.2019

MedicalResearch.com Interview with: E. van Eekelen, MSc | PhD Candidate Leiden University Medical Center Dept. Clinical Epidemiology Leiden, The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Fatty liver, defined as excess accumulation of fat within the liver, covers a broad clinical spectrum and is the leading cause of chronic liver diseases. It has also been linked to type 2 diabetes and cardiovascular disease. The consumption of alcohol is a well-established risk factor for fatty liver. However, we hypothesized that consumption of non-alcoholic energy-containing beverages also leads to liver fat accumulation. We analysed data from the Netherlands Epidemiology of Obesity (NEO) study, which is a prospective population-based cohort study including non-invasive measurements of liver fat content by magnetic resonance spectroscopy. Besides consumption of alcoholic beverages, sugar sweetened beverages were associated with more liver fat. We specifically showed that replacement of alcoholic beverages with milk was associated with less liver fat, whereas replacement with sugar sweetened beverages was associated with a similar amount of liver fat, even when taking calories into account.

What are the main findings? Response: Sugar-sweetened beverage consumption has been linked to many negative health conditions, such as weight gain, dental caries, and type 2 diabetes. Previous research found that when you replace sugar-sweetened beverages (SSBs) with water intake then total energy intake goes down. We wanted to know how many calories from SSBs children consume when they drink water or not since sugar-sweetened beverages are often used as a replacement for water. SSB intake has been falling among children over the last 15 years, but there are still pockets and sub-populations that have high consumption levels. It is critical to identify which kids are particularly at risk for high SSB intake since this can lead to these negative health effects. Overall we found that kids that did not consume any plain water (from tap or bottled water) consumed almost twice as many calories and percent of total calories from sugar-sweetened beverages than kids that consumed water. And for the sample overall that translated to nearly 100 extra calories on a given day. 
Author Interviews, Brigham & Women's - Harvard, Heart Disease, Red Meat / 22.04.2019

MedicalResearch.com Interview with: [caption id="attachment_48738" align="alignleft" width="158"]Marta Guasch-Ferre, PhD Research Scientist, Dept of Nutrition, Harvard TH Chan School of Public Health Instructor of Medicine, Channing Division of Network Medicine, Harvard Medical School Boston, MA, 02115 Dr. Guasch-Ferré[/caption] Marta Guasch-Ferre, PhD Research Scientist, Dept of Nutrition Harvard TH Chan School of Public Health Instructor of Medicine, Channing Division of Network Medicin Harvard Medical School Boston, MA, 02115   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Previous findings from randomized controlled trials evaluating the effects of red meat on cardiovascular disease risk factors have been inconsistent. But our new study, which makes specific comparisons between diets high in red meat versus diets high in other types of foods, shows that substituting red meat with high-quality protein sources lead to more favorable changes in cardiovascular risk factors. That is, to properly understand the health effects of red meat, it’s important to pay attention to the comparison diet. People do not simply eat more or less meat – it will almost always be in substitution with other foods. 
Author Interviews, Coffee / 19.04.2019

MedicalResearch.com Interview with: Eugene Chan, PhD Senior Lecturer in Marketing Monash Business School Monash University Australia and  Sam Maglio PhD Associate Professor of Marketing Department of Management University of Toronto  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The physiological effects of coffee and caffeine consumption have been well-studied, but we were interested in the psychological effects. Especially in Western societies, there is a mental association between coffee and arousal – that coffee is an arousing beverage. This led us to ask, might this association itself produce the psychological “lift” without actually drinking beverages? We found that it does. Merely seeing pictures of coffee or thinking about coffee can increase arousal, heart rates, and make people more focused. The effects are not as strong as actually drinking coffee of course, but they are still noticeable.

Ghannoum, PhD Director of the Center for Medical Mycology Case Western Reserve School of Medicine and UH MedicalResearch.com: What are the main findings?  Response: The driving force for this study was our finding that patients with Crohn’s disease had a significantly high level (or abundance) of pathogenic fungi (called Candida tropicalis) as well as bacteria (Escherichia coli, and Serratia Marcescens) compared to their non-diseased first-degree relatives. Not only were their levels high, but these organisms cooperated to form polymicrobial digestive plaque (or digestive biofilms) that aggravated the inflammatory symptoms in these patients. Based on this we wanted to develop a probiotic that targeted these organisms and the biofilms they form. Our efforts led to the design of the novel Biohm probiotic which we tested and the results were described in our publication.

MedicalResearch.com Interview with: Saeed Mastour Alshahrani, MPH, PhD School of Public Health, Loma Linda University, California, USA College of Applied Medical Sciences, King Khalid University Abha, Saudi Arabia  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: -The consumption of red and processed meat has been associated with risks of importance to public health including cardiovascular diseases and cancer. Several studies have found that red and processed meat intake was associated with an increased risk of mortality. However, levels of meat intake in those studies were relatively high. It remains of interest whether even relatively low intake levels of red and processed meat might be associated with greater mortality, compared to zero intake.

MedicalResearch.com Interview with: Professor Sofia B. Villas‐Boas Ph.D and Scott Kaplan, Ph.D. Candidate Department of Agricultural & Resource Economics, University of California, Berkeley, CA 94720‐3310  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background leading up to this study is the fact that  in 2014, the city of Berkeley passed the nation’s first sugar-sweetened beverage tax, also called soda tax, through a 75% YES public vote. Using beverage sales data from U. C Berkeley campus retailers, we find that sales of soda fell relative to non-SSB beverages by 10-20% after the election outcome and before the tax was ever passed on to consumers. We know this to be the case because the campus only passed through the higher prices to consumers in middle of 2016. This effect is also found when we look at beverage sales in retail outlets near U C Berkeley. There, quantity dropped after the Yes election outcome relative to quantity changes in counterfactual stores (in retailers near other U C campuses where the tax was not passed and with comparable patterns of sales to those in the city of Berkeley at baseline).

What are the main findings? Response: In 2016 our group published the findings of the Antenatal Late Preterm Steroids (ALPS) trial in the NEJM.  We found that administration of antenatal corticosteroids to women at high risk for delivery from 34-36 weeks decreased breathing problems in their neonates.  This treatment had been traditionally only given at less than 34 weeks. The current paper is a cost analysis of that trial.  We found that the treatment was also cost effective.  From a cost perspective treatment was both low cost and highly effective (the options are low cost, low effect/low cost/high effect, high cost/low effect, high cost/high effect).

Response: The prevalence of overweight and obesity has increased in the US, along with documented increases in portion size in the food supply. Fast food is popular, making up about 11% of adult daily calorie intake in the US, and over 1/3 of U.S. adults eat at fast food establishments on any given day. We therefore sought to examine changes in portion size, calories, and selected nutrients in fast-food entree, side, and dessert menu items across the years 1986, 1991, and 2016.

What are the main findings? Response: More than 40 million Europeans experience a major depressive disorder. One in ten men, and one in five women suffer from clinical depression at least once during their lifetime. Depression is one of the most prevalent and disabling disorders in the EU. Given the increasing prevalence of depression, more people are actively searching for ways to decrease their risk through lifestyle modification, but are often overwhelmed by confusing and contradictory information. The MooDFOOD prevention trial is the largest randomized clinical trial to study the effects of nutritional strategies on the prevention of major depressive disorder. Over 1000 overweight or obese participants identified as being at elevated risk for depression but who were not currently depressed, from four European countries -the Netherlands, the United Kingdom, Germany and Spain, took part in the study. Participants were randomized to either take nutritional supplements containing folic acid, vitamin D, zinc, selenium or to a pill placebo, and half of participants also received a behavioral lifestyle intervention intended to change dietary behaviors and patterns.

Angell, MD MPH Division of General Medicine Department of Medicine, Columbia University Irving Medical Center New York, NY   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Trans fatty acid in the diet increases the incidence of coronary heart disease in the population. In 2006, a policy restricting restaurant use of trans fat went into effect in NYC. This study measured the change in trans fatty acid serum concentration among a representative sample of the NYC population between 2004 and 2013-2014, and whether the change varied by frequency of restaurant food dining. Overall, blood trans fatty acid serum concentration went down by 57%. Among people who dined out less than one time a week, it went down 51% and in those who dined out 4 or more times a week, it went down 61.6%.  In fact, in 2013-2014 there was no longer a significant increase in the serum trans fatty acid concentrations among those who ate restaurant foods frequently compared with those who ate out rarely.

Coe Professorship in Nephrolithiasis and Mineral Metabolism Research Director, Hypertension Section, Cardiology Division, UT Southwestern Medical Center    MedicalResearch.com: What is the background for this study? Response: Increased sedentary activity is commonly seen in people who regularly consume fast food but previously studies have not identified potential mechanisms beyond increased obesity and lack of motivation. Our study seeks to determine if inorganic phosphate, a commonly used food additives that are present in up to 70% of foods in the American diet, maybe the culprit. These food additives (which may come in the form of monocalcium phosphate, phosphoric acid, or tetrasodium phosphate, etc. are used to make the food taste better and/or last longer. It is found mostly in prepackaged foods, cola drinks, and bakery items (cookies, cake, and bread). This is very different from organic phosphates that are found naturally in many healthful foods, such as fruits and vegetables, which are not not readily absorbed from the GI tract. In the Dallas Heart Study, a multiethnic population-based study, we found that serum phosphate is significantly associated with sedentary time and increased time spent in moderate-to-vigorous physical activity which was measured by wrist actigraphy device. This is not explained by reduce cardiac function as ejection fraction remains normal at higher serum phosphate.

Response: This is the largest study of the effects of artificially sweetened beverages (ASB) in older women from the Women's Health Initiative Observational Study which started in 1993 and still continues to follow the women. A prior paper indicated excess risk of cardiovascular disease with high consumption of ASBs, but cardiovascular disease was a composite endpoint combining stroke, coronary heart disease, heart failure, revascularization and peripheral arterial disease.  Our study focusses on stroke by itself and with different subtypes of stroke. We define high consumption as two or more 12 fl oz. of diet drinks (diet soda or fruit drinks) per day and low consumption as no or less than one drink per week.

Beavers PhD, MPH, RD Assistant Professor, Department of Health and Exercise Science Department of Biostatistical Sciences Wake Forest School of Medicine Winston-Salem, NC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Weight loss recommendation for older adults with obesity is controversial, in part because overall weight loss is accompanied by loss of muscle and bone, which may exacerbate age-related risk of disability and fracture. Identification of interventions that can preserve muscle and bone while promoting fat loss should maximize cardiometabolic benefit, while minimizing potential harm to the musculoskeletal system. This randomized controlled trial was originally designed to test whether a higher protein, nutritionally complete meal plan could preserve lean mass and mobility in older adults undergoing a six month intentional weight loss program. Four publications have resulted from this study: * “Effect of an Energy-Restricted, Nutritionally Complete, Higher Protein Meal Plan on Body Composition and Mobility in Older Adults with Obesity,” Journals of Gerontology: Medical Sciences, published online in advance of print June 21, 2018 * “Effect of a Hypocaloric, Nutritionally Complete, Higher-Protein Meal Plan on Bone Density and Quality in Older Adults With Obesity,” American Journal of Clinical Nutrition, published online in advance of print Jan. 9, 2019 * “Effect of Intentional Weight Loss on Mortality Biomarkers in Older Adults With Obesity,” Journals of Gerontology: Medical Sciences, published online in advance of print Aug. 20, 2018 * “Effects of a Hypocaloric, Nutritionally Complete, Higher Protein Meal Plan on Regional Body Fat and Cardiometabolic Biomarkers in Older Adults with Obesity,” Annals of Nutrition and Metabolism, published online in advance of print Feb. 11, 2019 Across the four publications, we found that: * Participants lost about 18 pounds, most of it fat (87 percent), and preserved muscle mass. The control group lost about half a pound. * Even when participants lost weight, they maintained bone mass. In fact, trabecular bone score, a measure of bone quality which predicts fracture risk, seemed to improve. * Fat was lost in the stomach, hips, thighs and rear, which is important for preventing or controlling cardiometabolic diseases such as diabetes and stroke. * Participants’ score on the Healthy Aging Index, which measures biomarkers that predict mortality and longevity, improved by 0.75 points.

We examined this in the setting of a monitored feeding study where adults ate each of 3 different sodium levels for 4 weeks at a time. Participants took 5 day breaks between sodium levels and ate the sodium levels in random order. We tested the hypothesis that lowering sodium would worsen how much lightheadedness the study participants reported.

Response: With more than 150 million working adults in the United States, workplaces represent a far reaching setting for chronic disease prevention and health promotion. While research suggests that workplace wellness efforts can be effective at changing health behaviors, little is known about the foods that people acquire at work. In this study, we used data from the US Department of Agriculture Food Acquisition and Purchasing Survey (FoodAPS) to investigate workplace food acquisitions among employed adults during a 7 day study period. The foods we examined included those purchased in places like cafeterias and vending machines as well as those acquired for free at meetings, social events, common areas, or shared by coworkers. They did not include foods brought from home by someone to eat at work themselves or food acquired by the employee at offsite restaurants.

What are the main findings? Response: Many patients take over-the-counter medications to held their cancers. Some of these remedies may be helpful; others are potentially harmful. Anti-oxidant medications are frequently selected by patients as they are inexpensive and available. We were approached by a high school student, Macy Williams (one of the authors) to do some research in our laboratory when she won a research scholarship (the 2016 Emperor Science Award) from Stand Up to Cancer. She worked with us several times per week doing experiments during her senior year of high school. When she graduated, we continued the work that she started. We studied effects of Vitamin D3, Melatonin, and alpha-Lipoic Acid on glioblastoma cells, a highly malignant brain tumor. We included experiments of these agents alone and in combination with Temozolomide, a chemotherapy agent used as standard of care in glioblastoma. The work was done in cultured cells, measuring growth and survival of cells. We used concentrations that could be achieved by oral intake of the drugs. We found that antioxidant medications, particularly alpha Lipoic Acid, had synergistic effects with Temozolomide – that is Temozolomide impair glioblastoma cell growth and survival better when combined with an antioxidant. The mechanism of action may be through reactive oxygen species.

Microbiome, Nutrition, Weight Research / 22.01.2019

The obesity rate has climbed steadily for men in the United States, currently rolling in at nearly 38% and still rising. That’s far from good news, and it’s doing nothing to help with the growing cardiovascular and heart disease statistics. Fighting obesity can be incredibly difficult, especially with our increasingly sedentary lifestyles brought on by modern conveniences. With diets popping up every day, it can be hard to pick, but one diet has arisen with a focus on digestive and general body health rather than strict weight loss: fiber-high diets. What is it? Fiber-high diets are exactly what they sound like, in that they’re dietary plans based on consuming fiber heavy foods to help promote a healthy digestive system. Our gut is home to massive colonies of helpful bacteria that work to aid us in breaking down our food and keep our body healthy. Fiber-high diets focus on feeding these bacteria the best possible fuel to promote a healthy body system, commonly referred to as the microbiome.

What are the main findings? Response: Transgenerational, epigenetic, response, has been shown in studies of animals and plants. Does it apply to humans? Previous findings of associations between grandparents early nutrition and grandchildren’s mortality have been controversial.  Two reasons for this: evidence in human studies has been based on rather small numbers and potential mechanisms are not very well understood. We have tested the hypothesis that there is “a male line transgenerational response” to nutritional events in pre-puberty in a study much larger than previous ones. We find support for this hypothesis in that boys who enjoyed unusually good access to food during their “slow growth period” (aged 9-12 years) seem to transmit a mortality risk on their grandsons but not granddaughters, in particular for cancer.

MedicalResearch.com Interview with: [caption id="attachment_46414" align="alignleft" width="117"]Samia Mora, MD, MHS Associate Professor of Medicine Harvard Medical School Director, Center for Lipid Metabolomics Brigham and Women’s Hospital Boston, MA Dr. Mora[/caption] Samia Mora, MD, MHS Associate Professor of Medicine Harvard Medical School Director, Center for Lipid Metabolomics Brigham and Women’s Hospital Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Mediterranean diet is rich in plants (nuts, seeds, fruits, vegetables, whole grains, legumes) and olive oil, and includes moderate intake of fish, poultry, dairy, and eggs, and alcohol, and rare use of meats and sweets.The Mediterranean diet has been associated with lower risk of cardiovascular disease (CVD) events but the precise mechanisms through which Mediterranean diet intake may reduce long-term risk of CVD are not well understood. We aimed to investigate the biological mechanisms that may mediate this cardiovascular benefit. Using a prospective study of 25,994 initially healthy women enrolled in the Women’s Health Study who were followed up to 12-years, we evaluated potential mediating effects of a panel of biomarkers (in total 40 biomarkers) that represent different CVD pathways and clinical factors. Higher baseline intake of a Mediterranean-type diet was associated with approximately one quarter lower risk of CVD events during the 12 year follow up. For the MED-CVD risk reduction, biomarkers of inflammation, glucose-metabolism/insulin-resistance, and adiposity contributed most to explaining the association, with additional contributions from pathways related to blood pressure, lipids – in particular HDL or triglyceride-rich lipoprotein metabolism, and to a lesser extent LDL cholesterol, branched chain amino acids, and small molecule metabolites.

Steen, Jr., M.D. Interventional Cardiologist Loyola University Medical Center Dr. Steen[/caption] Dr. Lowell H. Steen, Jr., M.D. Interventional Cardiologist Loyola University Medical Center Dr. Steen discusses how holiday treats & stress can increase the risk of heart attack. MedicalResearch.com: What are the main factors that are linked to an increase in heart related adverse events during the Christmas holiday season? Who is most at risk?  Response: The increase in holiday season heart-related hospitalizations and deaths are due to a variety of behaviors such as putting off seeking medical help until after the holidays, overeating rich foods, strenuous travel, excessive alcohol consumption and stressful family interactions. These factors can all trigger heart issues. Factors such as age, diabetes, high cholesterol and smoking all increase heart risk. Additionally, those with high blood pressure, which is a leading risk factor for heart disease and stroke, are exceptionally at risk and should celebrate the hectic holiday season with caution.

What are the main findings? Response: The digital attention of scientific articles can be readily quantified using the Altmetric score. The Altmetric score is a weighted measure, incorporating a variety of media platforms. We aimed to characterize the Top 10% of articles by Altmetric score among 4 major cardiovascular journals (Circulation, European Heart Journal, Journal of the American College of Cardiology, and JAMA Cardiology) in 2017. Our primary findings were: 1) nearly half of the most disseminated articles were not original research investigations, 2) the most common article topic was nutrition/lifestyle, and 3) there was a weak but significant correlation between Altmetric scores and citation number.

Response: Vomiting and diarrhea remain extremely common diseases in children and are the most common reason children are brought for emergency department care in North America.  While we have options to reduce vomiting there historically has been little physicians can offer to reduce the severity of the diarrhea. Probiotics have recently emerged as an option with some early evidence of benefit in clinical trials but the studies performed to date have been small and few little research has been conducted in North America in outpatient or emergency department children. The one study to date that was performed in a US emergency department did not find probiotic use to be beneficial.  Given the increasing importance of clarifying this issue we undertook this study.
