Author Interviews, Diabetes, Heart Disease / 06.09.2019

MedicalResearch.com Interview with: Jose Carlos Nicolau, MD PhD Heart Institute University of Sao Paulo Medical School, Sao Paulo, Brazil  MedicalResearch.com: What is the background for this study? Response: There are few evidence about the late phase (1-3 years) of patients with diabetes and myocardial infarction, especially regarding quality of life (qol) and health resource utilization. Our study showed that the population with diabetes (dm), compared with the population without diabetes, have worse quality of life, more hospitalizations, and when hospitalized showed a longer hospital stay. Additionally, as expected, dm population have worse outcomes, including the composite of cv death, myocardial infarction or stroke, and all-cause death. (more…)

MedicalResearch.com Interview with: Prof. John McMurray Professor of Cardiology Institute of Cardiovascular & Medical Sciences University of Glasgow MedicalResearch.com: What is the background for this study? Response: SGLT2 inhibitors prevent the development of heart failure (HF) in patients with type 2 diabetes (T2D) – can they be used to treat patients with established heart failure? Also, although introduced as a glucose-lowering treatment for T2D, experimental evidence suggests these drugs may have non-glucose mediated benefits. So, might they be a treatment for HF even in patients without diabetes?  (more…)
Author Interviews, Diabetes, Heart Disease / 06.09.2019

MedicalResearch.com Interview with: Nicolas Danchin MD, FESC Professor of Medicine, Consultant Cardiologist Intensive Cardiac Care Unit Hôpital Européen Georges Pompidou Paris, France MedicalResearch.com: What is the background for this study? Response: FAST-MI is a programme of nationwide French surveys, carried out every 5 years in France since 2005 in patients hospitalised with STEMI or NSTEMI. Patients are included consecutively for one month and 10-year follow-up is organized. We can thus analyse patients' outcomes in relation with their profile. Knowing that diabetic patients represent a large proportion of patients with AMI, we thought it would be worthwhile determining whether they suffered specific complications, and in particular, heart failure, both at the acute stage and in the subsequent months.

MedicalResearch.com Interview with: Prof. Dr. Christoph Kaleta Institute for Experimental Medicine Institute for Experimental Medicine, Kiel University Kiel, GermanyProf. Dr. Christoph Kaleta Institute for Experimental Medicine Institute for Experimental Medicine, Kiel University Kiel, Germany  MedicalResearch.com: What is the background for this study? Response: Even though Metformin is the first-line treatment option in type-2 diabetic patients, its specific mechanism of action has remained elusive so far. Moreover, metformin is of particular interest as an anti-aging drug since it's usage has been shown to be associated with a lower incidence of several aging diseases in type-2 diabetic patients taking metformin when compared to matched healthy controls. While previous work was able to show pronounced changes in the microbiota of patients taking metformin and a health-promoting effect of metformin-adapted microbiota, how this beneficial effect could be mediated has remained unclear.

Author Interviews, BMJ, Diabetes, Lipids, Omega-3 Fatty Acids / 23.08.2019

MedicalResearch.com Interview with: Lee Hooper PhD, RD Reader in Research Synthesis, Nutrition & Hydration Norwich Medical School University of East Anglia England, UK MedicalResearch.com: What is the background for this study? Response: The World Health Organization asked us to carry out a set of studies (systematic reviews of randomised controlled trials) assessing health effects of omega-3 and omega-6, which are polyunsaturated fats. This is because the WHO are planning to update their dietary guidance on fats in the near future. Worries about effects of long chain omega-3 on control of diabetes have long existed, and some experimental studies have suggested that omega-3 supplementation and diets high in PUFA and omega-3 raise fasting glucose. Pollutants such as methylmercury and polychlorinated biphenyl levels exceeding recommended thresholds are rarer now, but have been reported in seafoods and fish oil supplements; elevated mercury levels interrupt insulin signalling, raising fasting glucose, in mouse models. Body concentrations of organic pollutants are correlated with prevalence of diabetes in the US, but other cross sectional studies have suggested either no association with or benefits of eating fish on glycaemic control. Systematic reviews of observational studies have suggested both positive and negative associations with glucose metabolism, but strong evidence shows that omega-3 supplements reduce raised triglycerides and have little or no effect on body weight. Theories suggest that omega-3 and omega-6 fats compete in some metabolic pathways so that the omega-3/omega-6 ratio is more important than absolute intakes of either.  (more…)
Author Interviews, Diabetes, JAMA, PTSD / 21.08.2019

MedicalResearch.com Interview with: Jeff Scherrer, Ph.D. Associate professor; Research director Department of Family and Community Medicine Saint Louis University Center for Health Outcomes Research  MedicalResearch.com: What is the background for this study? Response: This study was part of a larger NIH grant to determine if PTSD is associated with poor health behaviors and subsequently whether PTSD remains an independent risk factor for diabetes and heart disease.  Our second focus of the grant was to measure if those patients who experience clinically meaningful PTSD improvement have improved health behaviors (e.g. seeking help to lose weight) and a lower risk for diabetes and heart disease. The rationale for this study of PTSD improvement and lower risk for diabetes is supported from other investigators' findings that PTSD treatment completion is often followed by improvement in sleep, depression, pain and general physical complaints and lower blood pressure.  Because we have found the association between PTSD and incident diabetes is largely explained by obesity, depression and other comorbid conditions that are more common in patients with vs. without PTSD, we hypothesized that improvements in PTSD would be associated with lower risk of diabetes either directly or due to improvements in these comorbid diabetes risk factors.

MedicalResearch.com Interview with: Pooyan Kazemian, Ph.D. Instructor in Medicine Massachusetts General Hospital  MedicalResearch.com: What is the background for this study? Response: Advances in diabetes care can meaningfully improve outcomes only if they effectively reach the populations at risk. However, it is not known if recent innovations in diabetes treatment and care models have reached the United States population at risk. (more…)
Author Interviews, Diabetes, Pediatrics / 09.07.2019

MedicalResearch.com Interview with: Nelly Mauras, MD Chief, Division of Pediatric Endocrinology, Nemours Children’s Health System Professor of Pediatrics Mayo College of Medicine MedicalResearch.com: What is the background for this study?   Response: Keeping blood sugars close to normal in young children with diabetes is often limited by parental fears of the risks of low blood sugars and impaired cognitive development. Dr. Nelly Mauras, at the Nemours Children’s Health System in Jacksonville FL, along with Dr. Allan Reiss at Stanford University are co-principal investigators of the Diabetes Research in Children Network, a 5-center consortium performing studies in children with diabetes, also including the University of Iowa, Washington University St Louis and Yale University. The investigators recruited 144 children with type 1 diabetes who were 4-7 years old and performed brain imaging (MRIs), did special cognitive tests, and monitored blood sugars using continuous glucose monitors. These studies were repeated after 18 months, approximately 54 months and 74 months, to examine changes in the brain and compare the results with those of 70 children the same age who do not have diabetes.

Author Interviews, CDC, Cost of Health Care, Diabetes / 09.07.2019

MedicalResearch.com Interview with: Xiaohui Zhuo, PhD Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention, Atlanta, GA  MedicalResearch.com: What is the background for this study? Response: Prescription drug spending (spending from families and individuals, their medical providers (doctors, hospitals, pharmacies, etc.) and employees across the United States) has increased at a much higher rater than other components of the total medical expenditure associated with diabetes.  The share of spending on prescription drugs in per capita annual excess expenditure due to diabetes increased from 27% to 41% between 1987 and 2011, according to a previous study using national data from the Agency for Healthcare Research and Quality Medical Expenditures Panel Surveys. In this most recent study, CDC researchers estimated the increase in the national spending on antidiabetic drugs from 2005 to 2016 in total and by drug class and broke down the increase in total national spending by examining what factors have contributed to the increase estimating the magnitude of each factor’s contribution.

AstraZeneca, Author Interviews, Diabetes, Kidney Disease / 24.06.2019

MedicalResearch.com Interview with: Naeem Khan MD Vice President at AstraZeneca  MedicalResearch.com: What is the background for this study? What are the main findings? Response: A pre-specified exploratory analysis of renal data from the DECLARE-TIMI 58 trial, the largest SGLT-2 inhibitor (SGLT-2i) cardiovascular outcomes trial (CVOT) conducted to date, showed that FARXIGA (dapagliflozin) reduced the composite of kidney function decline, end-stage renal disease (ESRD) or renal death by 47% in patients with type 2 diabetes (T2D). Additionally, FARXIGA reduced the relative risk of a cardio-renal composite of kidney function decline, ESRD, or renal or cardiovascular (CV) death by 24% compared to placebo. The analysis evaluated 17,160 patients with type 2 diabetes and predominantly preserved renal function, irrespective of underlying atherosclerotic CV disease (ASCVD). (more…)
Author Interviews, Diabetes, NIH, Pediatrics / 18.06.2019

MedicalResearch.com Interview with: Dr. Ellen Leschek MD Program Director: Division of Diabetes, Endocrinology, and Metabolic Diseases The National Institute of Diabetes and Digestive and Kidney Diseases Health Information Center MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Type 2 diabetes (T2D) is thought to be characterized by a progressive loss of pancreatic beta cell (insulin producing/releasing cell) function. For this reason, T2D medications eventually stop working and individuals with T2D require treatment with insulin. The Restoring Insulin Secretion (RISE) Consortium was established by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to evaluate the effects of treatment and treatment withdrawal on the loss of pancreatic beta cell function. In the RISE Study, progression of disease was assessed by the measurement of pancreatic beta cell function in youth and adults who had either impaired glucose tolerance (IGT; prediabetes) or recently diagnosed Type 2 diabetes before, during and after treatment with study medications. Importantly, the RISE Pediatric Medication Study and the RISE Adult Medication Study were designed in tandem to allow direct comparison of the effects of two pharmacologic treatment regimens (the only two FDA-approved medications for Type 2 diabetes in youth) on disease progression in youth and adults.

Author Interviews, Diabetes, Transplantation / 12.06.2019

MedicalResearch.com Interview with: Dr. Rodolfo Alejandro, MD Professor of Medicine University of Miami Miller School of Medicine Co-Director of the Cell Transplant Center Director/Attending Physician of the Clinical Cell Transplant Program Diabetes Research Institute www.DiabetesResearch.org  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In type 1 diabetes, the insulin-producing islets cells of the pancreas have been mistakenly destroyed by the immune system, requiring patients to manage their blood sugar levels through a daily regimen of insulin therapy. Islet transplantation has allowed some patients to live without the need for insulin injections after receiving a transplant of donor cells. Some patients who have received islet transplants have been insulin independent for more than a decade, as DRI researchers have published. Currently, islet transplantation remains an experimental procedure limited to a select group of adult patients with type 1 diabetes.Although not all subjects remain insulin independent, like the subjects described in this presentation, after an islet transplant a significant number of them continue with excellent graft function for over 10 years that allows them to have near-normal glucose metabolism in the absence of severe hypoglycemia on small doses of insulin. In 2016, the National Institutes of Health-sponsored Clinical Islet Transplantation Consortium reported results from its Food and Drug Administration (FDA)-authorized Phase 3 multi-center trial, of which the DRI was a part, indicating that islet transplantation was effective in preventing severe hypoglycemia (low blood sugar levels), a particularly feared complication in type 1 diabetes that can lead to seizures, loss of consciousness and even death. The study was a significant step toward making islet transplantation an approved treatment for people with type 1 diabetes and reimbursable through health insurance, as it is in several other countries around the world.   (more…)
Author Interviews, Diabetes, Weight Research / 11.06.2019

MedicalResearch.com Interview with: Kalypso Karastergiou, MD, PhD Assistant Professor, Medicine, Endocrinology, Diabetes and Bone Disease Diabetes, Obesity and Metabolism Institute Icahn School of Medicine at Mount Sinai  MedicalResearch.com: What is the background for this study?   Response: Multiple studies, epidemiological as well as clinical, have established that body shape is an important and independent predictor of cardiovascular and metabolic disease risk and ultimately total mortality. Subjects that preferentially store weight in the abdominal area (often described as android, upper-body or apple-shape obesity) are at increased risk, whereas those who preferentially store weight in the lower body, in the gluteofemoral area (gynoid, lower-body or pear-shape), appear to be protected. The former is more common in men, whereas the latter in women, especially premenopausal women. The overarching questions in the field are:
  • What factors determine body shape?
  • Why are subjects with lower-body shape protected?
  • Can we exploit the physiological and pathophysiological mechanisms involved to improve stratification, prevention or treatment of obesity and related diseases?

Author Interviews, Diabetes, Vitamin D / 09.06.2019

MedicalResearch.com Interview with: Anastassios G. Pittas, M.D MS Professor Co-Director, Diabetes and Lipid Center; Tufts Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Observational studies have consistently reported an association between low blood vitamin D level and development of type 2 diabetes. However, whether vitamin D supplementation lowers risk of developing diabetes is not known. We designed and conducted the Vitamin D and diabetes (D2d) study to answer this question.  We randomized 2,423 people with prediabetes to 4,000 IU/day of vitamin D3 or placebo and followed them for new-onset diabetes with blood tests every 6 months for an average of 2.5 years. About 80% of participants had sufficient vitamin D level at baseline (25-hydroxyvitamin D level >= 20 ng/mL). The trial was designed to show a reduction of 25% or more in diabetes risk with vitamin D. The study was unable to show a reduction of 25% or more. At the end of the study, there was a 12% reduction in risk of developing diabetes with vitamin D, which missed statistical significance (hazard ration 0.88; 95% confidence interval 0.75 to 1.04). In a small subgroup of participants with vitamin D deficiency at baseline (25-hydroxyvitamin D level < 12 ng/mL) there was 62% reduction in risk of diabetes with vitamin D (hazard ration 0.38; 95% confidence interval 0.18 to 0.80).

Author Interviews, Diabetes, Diabetologia, Stroke / 09.06.2019

MedicalResearch.com Interview with: Rongrong Yang, PhD candidate Tianjin Medical University  MedicalResearch.com: What is the background for this study? Response: Worldwide, cerebrovascular disease (CBD) and type 2 diabetes mellitus (T2DM) are common disorders that have become among the top ten leading causes of death, killing approximately 8 million people in 2016. Both T2DM and CBD are complex genetic and lifestyle-related disorders. Genetic and familial environmental factors (e.g. foetal environment, maternal smoking and childhood socioeconomic status) have been shown to be involved in the development of both conditions. Accumulating evidence from previous studies suggests that T2DM is independently associated with an increased risk of CBD, especially ischemic CBD. (more…)
Author Interviews, Diabetes, Ophthalmology / 20.05.2019

MedicalResearch.com Interview with: Thulasiraj Ravilla Executive Director – LAICO & Director – Opeations Aravind Eye Care System Tamilnadu, India  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Diabetic Retinopathy (DR) is a visual consequence of diabetes and various other studies have reported that in India, 10% to 30% of adults with diabetes have DR, with higher rates found in older people and urban areas. Undetected DR leads to vision loss and eventually blindness. Thus early identification of DR is critical to initiate appropriate treatment to reduce the rate of vision loss. Conventional approaches of requesting diabetologists to refer patients with diabetes to an ophthalmologist has been ineffective due to compliance issues, both by the diabetologists and the patients. Similarly screening through outreach eye camps have not been found to be effective in India and other developing countries owing to inadequate eye care resources. Teleretinal screening for Diabetic Retinopathy is increasingly being used in India. Evidence from randomized clinical trials on the benefits of teleretinal screening is limited. Whatever evidence is there are from high income countries, which often have little relevance to developing countries. (more…)
Author Interviews, Diabetes, Ophthalmology, Regeneron / 17.05.2019

MedicalResearch.com Interview with: Robert L. Vitti, MD, MBA Vice President and Head, Ophthalmology Regeneron Pharmaceuticals Dr. Vitti discusses the recent announcement that the FDA has approved EYLEA to treat all stages of diabetic retinopathy. MedicalResearch.com: Can you provide additional background on this approval? Would you briefly explain diabetic retinopathy and it's impact on patients? Response: The FDA has approved EYLEA (aflibercept) Injection to treat all stages of diabetic retinopathy (DR). DR is the leading cause of blindness among working-aged American adults. Approximately 8 million people live with DR, a complication of diabetes characterized by damage to the blood vessels in the retina (per 2010 data). The disease generally starts as non-proliferative diabetic retinopathy (NPDR) and often has no warning signs or symptoms. Over time, NPDR often progresses to proliferative diabetic retinopathy (PDR), a stage in which abnormal blood vessels grow on the surface of the retina and into the vitreous cavity, potentially causing severe vision loss.

MedicalResearch.com Interview with: foot-neuropathyMonica Perazzolo Research Centre for Musculoskeletal Science and Sports Medicine School of Healthcare Science, Faculty of Science and Engineering, Manchester Metropolitan University, Manchester, UK Department of Biomedical and Neuromotor Sciences University of Bologna, Bologna, Italy  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our research on motor control in diabetes focussed on the effect of diabetic peripheral neuropathy on driving. Drivers with diabetic peripheral neuropathy showed a less well controlled use of the accelerator pedal and sometimes larger, faster steering corrections needed to stay in lane when driving a simulator compared to healthy drivers and people with diabetes but no neuropathy. Despite these negative findings, an important result is that drivers with diabetic peripheral neuropathy demonstrated an improvement in their driving with practice.  (more…)
Author Interviews, BMJ, Diabetes, Prostate, Urology / 24.04.2019

MedicalResearch.com Interview with: Professor Ruth Andrew PhD Chair of Pharmaceutical Endocrinology University/BHF Centre for Cardiovascular Science Queen's Medical Research Institute University of Edinburgh  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our research group has been interested for a number of years in how stress hormones (called glucocorticoids) influence the risk of heart disease and diabetes. Glucocorticoids help us control stress and regulate how the body handles its fuel, for example the carbohydrate and fat we eat. However exposure to high levels of glucocorticoids, can increase the risk of diabetes, obesity and high blood pressure. We studied men with prostate disease who took 5α-reductase inhibitors, because over and above the beneficial actions of these drugs in the prostate, they also slow down inactivation of glucocorticoids. We had carried out some short term studies with the drugs in humans and found that they reduced the ability of insulin to regulate blood glucose. Therefore in the study we have just published in the BMJ, we examined how patients receiving these drugs long-term responded and particularly we were able to show that over an 11 year period that there was a small additional risk of developing type 2 diabetes, the type of disease common in older people, compared with other types of treatments.

MedicalResearch.com Interview with: Kishore M. Gadde, MD, Professor Fairfax Foster Bailey Endowed Chair in Heart Disease Prevention Medical Director, Clinical Services Pennington Biomedical Research Centre Baton Rouge, LA 70808  MedicalResearch.com: What is the background for this study? Response: Around 20 years ago, the Diabetes Prevention Program, DPP, enrolled 3,234 adults with excess body weight and impaired glucose tolerance. The idea was to compare the efficacy of either an intensive lifestyle intervention or metformin relative to placebo in preventing diabetes. Over approximately 3 years, both lifestyle and metformin were effective, but lifestyle intervention was better for weight loss as well as in reducing the risk of diabetes. After the blinded treatment phase ended, the researchers continued to follow this cohort in their originally randomised groups.  (more…)

Response: In 2018, almost 8% of people with diabetes who owned a smartphone used a diabetes app to support self-management. Currently, most apps are not regulated by the US Food and Drug Administration (FDA). We downloaded and assessed 371 diabetes self-management apps, to see if they provided evidence-based decision support and patient education.  (more…)
Author Interviews, Diabetes, Geriatrics, Stroke / 06.04.2019

MedicalResearch.com Interview with: Philippe Girard, MD, Gérontopôle de Toulouse, CHU Toulouse Toulouse, France MedicalResearch.com: What is the background for this study? Response: The idea for this study came about in 2016 when a systematic review assessing acetaminophen’s adverse event (AEs) profile came out with results suggesting increased mortality and morbidity (Paracetamol: not as safe as we thought? A systematic literature review of observational studies, PMID: 25732175). Pr Yves Rolland had collected data from his IQUARE study (Improving the Quality of Care of Long-Stay Nursing Home Residents in France, PMID: 26782872) including all prescriptions from over 6000 nursing home residents and all their medical history over an 18 month follow-up period. We thought it would be a good idea to assess the safety profile of acetaminophen on this geriatric population.  (more…)
Author Interviews, Diabetes, Genetic Research, JAMA, Mental Health Research, Schizophrenia / 03.04.2019

MedicalResearch.com Interview with: Prof Sabine Bahn MD PhD MRCPsych FRSB Cambridge Centre for Neuropsychiatric Research Jakub Tomasik, PhD Department of Chemical Engineering and Biotechnology University of Cambridge   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Schizophrenia patients are at increased risk of impaired glucose metabolism, yet the comorbidity between the two conditions cannot be fully explained by known risk factors such as obesity, smoking, stress or antipsychotic medication. Previous family and genome-wide studies have suggested that the co-occurrence between schizophrenia and impaired glucose metabolism might be due to shared genetic factors, as exemplified by increased risk of diabetes in first-degree relatives of schizophrenia patients, but the biological mechanisms underlying this association remain unknown. We examined the association between insulin resistance, schizophrenia polygenic risk and response to treatment in 58 drug-naive schizophrenia patients and 58 matched healthy individuals while controlling for a range of demographic (age, gender, body mass index), lifestyle (smoking, alcohol and cannabis use) and clinical (psychopathology scores, treatment drug) factors. We found that insulin resistance, a key feature contributing to the development of type 2 diabetes, significantly correlated with schizophrenia polygenic risk score in patients, with higher genetic risk of schizophrenia associated with increased insulin resistance. Furthermore, we found that patients with higher insulin resistance were more likely to switch medication during the first year of treatment, which implies lower clinical response.  (more…)
Author Interviews, Diabetes, Genetic Research, Heart Disease, Nature / 02.04.2019

MedicalResearch.com Interview with: Eirini Marouli William Harvey Research Institute Barts and The London School of Medicine and Dentistry, Queen Mary University of London, London MedicalResearch.com: What is the background for this study?   Response: Epidemiological studies suggest that shorter stature is associated with increased risk of coronary artery disease (CAD) or type 2 diabetes (T2D). It is not clear though whether these associations are causal or there are other factors mediating these effects. When randomized trials are inappropriate or impossible, we can use Mendelian Randomisation as a good alternative to study the causal relationship between a trait and a disease. Here, we examined over 800 places in the human genome known to be associated with adult height and evaluated how genetically predicted height can affect the risk of CAD or T2D. Furthermore, we evaluated the role of several risk factors including, cholesterol, triglycerides, blood pressure, body mass index, fat percentage, socio-economic parameters including education and income as well as lung function. Lung function was assessed by spirometry measures including FEV1: forced expiratory volume in 1 second, FVC: forced vital capacity. (more…)
Author Interviews, Diabetes, Heart Disease, UCSD / 28.03.2019

MedicalResearch.com Interview with: H. Kirk Hammond, MD Professor of Medicine at University of California San Diego Basic research scientist and cardiologist San Diego Veterans' Affairs Healthcare System Dr. Hammond is winner of the 2017 William S. Middleton Award – the highest research honor in the U.S. Department of Veterans Affairs  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Worldwide, 9% of adults have diabetes, predominantly due to insulin resistance, known as Type 2 diabetes. It is associated with obesity and diets high in fat and carbohydrates. In this gene transfer study we showed that a single injection of a vector encoding a natural hormone (urocortin 2, Ucn2) increased glucose disposal and improved heart function in a model of diet-induced Type 2 diabetes in mice.  (more…)
Author Interviews, Diabetes, Technology, UCSF / 12.03.2019

MedicalResearch.com Interview with: Robert Avram MD MSc Division of Cardiology University of California, San Francisco MedicalResearch.com: What is the background for this study? Would you briefly describe what is meant by Photoplethysmography? While analyzing the heart rate data as collected using smartphones apps in the Health-eHeart study, we noticed that diabetic patients had, on average, a higher ‘free-living’ heart rate than non-diabetic patients when adjusted from multiple factors. This pushed us to analyze the signal to see if there were other features that would help differentiate diabetes patients from non-diabetes patients. By identifying these features, we saw a huge opportunity to develop a screening tool for diabetes using deep learning and a smartphone camera and flash, in order to classify patients as having prevalent diabetes/no-diabetes. Photoplethysmography is the technique of measuring the difference in light absorption by the skin in order to detect blood volume changes in the microvasculature. Most modern mobile devices, including smartphones and many fitness trackers (Apple Wathc, FitBit), have the ability to acquire PPG waveforms, providing a unique opportunity to detect diabetes-related vascular changes at population-scale.  (more…)

MedicalResearch.com Interview with: Megan A McCrory, PhD, FTOS Research Associate Professor Dept of Health Sciences Sargent College of Health and Rehabilitation Sciences Boston University 02215 MedicalResearch.com: What is the background for this study? 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. (more…)
