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.

MedicalResearch.com Interview with: [caption id="attachment_50178" align="alignleft" width="150"]Nelly Mauras, MD Chief, Division of Pediatric Endocrinology, Nemours Children’s Health System Professor of Pediatrics Mayo College of Medicine Dr. Mauras[/caption] 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.

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.

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).

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.

MedicalResearch.com Interview with: [caption id="attachment_49716" align="alignleft" width="200"]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 Dr. Alejandro[/caption] 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.

MedicalResearch.com Interview with: [caption id="attachment_49712" align="alignleft" width="133"]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?   MedicalResearch.com: What are the main findings?   Response: Up to date, studies in body shape have focused on the distribution of the adipose (fat) tissue.  This report seeks to expand the investigation to other tissues as well. During the period from 1999-2006, 14,005 participants in the National Health and Nutrition Examination Survey (which represents the United States population), 20-69 years old, had a DXA test that allows total and regional estimation of fat, lean and bone tissue mass.   This preliminary analysis shows that body shape is determined by coordinated changes in the head, trunk and limbs that involve the fat, as well as the other tissues.     MedicalResearch.com: What should readers take away from your report?  Response: This is an observational study that doesn’t allow us to draw conclusion as to cause and effect or prediction of future risk. It does suggest that body shape is a whole-body feature with systematic, coordinated changes in all body compartments and tissues.   The observations should be replicated in other populations and in prospective studies.      MedicalResearch.com: What recommendations do you have for future research as a result of this work?  Response: This report generates more questions than it answers.   •	First of all, are there differences in the function of tissues that determine body shape between subjects with upper- versus lower body shape?   •	Which tissues drive differences in physiology and disease risk?   •	Can we identify the underlying molecular pathways?   •	Does any of these pathways represent a viable mechanistic target to prevent or treat disease and improve quality of life?     Dislosures The study is partly funded by grants from the MSHS Translational Science Hub at Icahn School of Medicine at Mount Sinai (KL2TR001435) and the Einstein-Sinai Diabetes Research Center in New York City.

Author Interviews, Diabetes, Vitamin D / 09.06.2019

MedicalResearch.com Interview with: [caption id="attachment_49667" align="alignleft" width="142"]Anastassios G. Pittas, M.D MS Professor Co-Director, Diabetes and Lipid Center; Tufts University School of Medicine Dr. Pittas[/caption] 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.

MedicalResearch.com Interview with: [caption id="attachment_49207" align="alignleft" width="150"]Thulasiraj RavillaExecutive Director – LAICO &Director – OpeationsAravind Eye Care SystemTamilnadu, India  Mr. Thulasiraj[/caption] 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.

DOI:10.15347/wjm/2014.010. ISSN 2002-4436. Illustration depicting diabetic retinopathy Illustration depicting diabetic retinopathy[/caption] 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. 
Author Interviews, BMJ, Diabetes, Prostate, Urology / 24.04.2019

MedicalResearch.com Interview with: [caption id="attachment_48763" align="alignleft" width="128"]Professor Ruth Andrew PhDChair of Pharmaceutical EndocrinologyUniversity/BHF Centre for Cardiovascular ScienceQueen's Medical Research InstituteUniversity of Edinburgh Dr. Andrew[/caption] 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.

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. 
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.

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.

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.

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.

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.

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.

MedicalResearch.com Interview with: Fariba Ahmadizar, PharmD, MSc, PhD Department of Epidemiology Erasmus University Medical Centre Rotterdam, the Netherlands MedicalResearch.com: What is the background for this study? Response: Several observational studies and trials have already reported an increased risk of incident type 2 diabetes in subjects treated with statins; however, most of them lack details, meaning that there were limited studies on the association of statin use with glycemic traits. Studies on this association underestimated type 2 diabetes incident cases due to including either questionnaire-based data, short follow-up time or lack of a direct comparison between different statin types, dosages and duration of use with respect to diabetes-related outcomes.

MedicalResearch.com Interview with: Giuseppe Pugliese, MD, PhD for the Italian Diabetes and Exercise Study 2 (IDES_2) Investigators Department of Clinical and Molecular Medicine ‘‘La Sapienza’’ University Diabetes Unit, Sant’Andrea University Hospital Rome, Italy MedicalResearch.com: What is the background for this study? Response: There is a growing epidemic of obesity and type 2 diabetes worldwide, which are causally related to the increasing prevalence of “physical inactivity”, i.e., an insufficient amount of moderate-to-vigorous physical activity according to current guidelines, and “sedentariness”, i.e., too many hours, especially if uninterrupted, spent in a sitting or reclined position.  These two unhealthy behaviors exert their detrimental effects independently of each other and are very common among people suffering from type 2 diabetes, who would therefore benefit from increasing physical activity and reducing sedentary time, as recommended by current guidelines. However, such a behavior change is generally difficult for a number of internal and external barriers and requires behavioral interventions targeting both physical activity and sedentary habits.  Unfortunately, there is no definitive evidence that this is indeed feasible and, particularly, that, if adopted, change in behavior can be maintained in the long term.

This because the Insulin Resistance Intervention after Stroke (IRIS) trial reported effects of pioglitazone in patients with stroke or TIA and insulin resistance assessed by the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) score for insulin resistance.1 ( However, few clinicians measure a HOMA-iR score, so the clinical impact of that trial was limited. In this study we analyzed the effect of pioglitazone in stroke/TIA patients with prediabetes, which is commonly assessed by clinicians. Prediabetes was defined by the American Diabetes Association: a glycosylated hemoglobin (A1C) of  5.7% to <6.5% (we did not do glucose tolerance tests).  We analyzed primarily the results for patients with 80% adherence, but also did  an intention-to-treat (ITT) analysis.  The reason for focusing on patients with good adherence was that pioglitazone cannot be taken by about 10-20% of patients, because of fluid retention and weight gain (mainly due  to fluid retention).  (The reasoning was that third party payers would not need to pay for the medication in patients who do not take it.) In stroke/TIA patients with good adherence, the benefits of pioglitazone were greater than in the original IRIS trial. We found a 40% reduction of stroke/MI, a 33% reduction of stroke, and an 80% reduction of new-onset diabetes, over 5 years.  Pioglitazone also improved blood pressure, triglycerides and HDL-cholesterol. As expected, pioglitazone was somewhat less beneficial in the ITT analysis. Fluid retention can usually be managed by reducing the dose of pioglitazone; even small doses still have a beneficial effect . Also, amiloride has been shown to reduce fluid retention with pioglitazone.

Johnston MD Professor and Chair, Neurology School of Medicine University of Virginia MedicalResearch.com: What is the background for this study? Response: We know that acute ischemic stroke patient with hyperglycemia at presentation have worse outcomes. We also know if we lower the glucose too low that this is bad for ischemic brain also. T he SHINE trial addressed a world wide debate about whether intensive treatment of hyperglycemia is beneficial. We assessed the efficacy and safety of an intensive glucose control protocol with a target glucose of 80-130 mg/dL compared to a more standard protocol with a target of less than 180 mg/dL.

MedicalResearch.com Interview with: Lene Ring Madsen, MD, Ph.d. Medicinsk Afdeling  Herning Hospitalsenheden Vest Lene Ring Madsen, MD, Ph.d. Medicinsk Afdeling  Herning Hospitalsenheden Vest MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know from previous studies that there is a significant chance of diabetes remission following Roux-en-Y gastric bypass, but most studies evaluate smaller cohorts of selected patients (e.g. from a single center or only patients covered by a specific type of insurance). By using Danish registries, which hold information on all Danish Citizens independent of social- or economic status and have complete follow-up, we wanted to evaluate the Roux-en-Y gastric bypass surgery (RYGB) in a real-world setting. The main findings are that more than 70 % of patients with obesity (BMI>35 kg/m2) and type 2 diabetes treated by RYGB had their diabetes go into remission or every 6-month period in the first 5 years after the procedure. Out of those who were in remission within the first year of follow-up 27% had undergone relapse at 5 years. The most important predictor of a patient not going into remission was if they required insulin to control their disease. Other factors included older age and higher starting HbA1c level. During the more than five years of follow-up, the risk of microvascular complications was 47% lower in the RYGB group than in the control population, with largest decreases in the risk of diabetic retinopathy and diabetic kidney disease. There was a smaller impact on the risk of macrovascular events, which were 24% lower among patients who had received bariatric surgery; however, this difference was not large enough to achieve statistical significance. The 90-day mortality was very low (<0.5%).

What are the main findings? Response: It is unclear if there is an association between type 1 diabetes and school performance in children. Some studies have found type 1 diabetes to be associated with worse performance, while others have found no differences. However, most of the existing literature are based on smaller, non-random samples of children with diabetes. In this study we used data on all public school children in the country of Denmark, involving more than 600,000 schoolchildren where approximately 2,000 had a confirmed diagnosis of type 1 diabetes. The children were tested in math and reading using a nationally standardized testing procedure, and we found no difference in the obtain test scores between children with diabetes compared to children without diabetes.
