What are the main findings? Dr. Larsen: We know that muscle is important for metabolic processes, but there has been very little research on the role muscle may play in the development of metabolic diseases like type 2 diabetes. While excess fat can increase the risk of metabolic disease, there are people who are normal weight who still develop diabetes, and it’s possible that this could be due to low muscle mass. Our main findings were that, in normal weight women, women with more abdominal, thigh, and overall muscle were less likely to develop diabetes over a 13-year period.

MedicalResearch.com Interview with: [caption id="attachment_23375" align="alignleft" width="117"]Christopher Sorli, MD SUSTAIN 1 investigator and Chair of the Department of Diabetes, Endocrinology and Metabolism Billings Clinic, Billings, Montana Dr. Christopher Sorli[/caption] Christopher Sorli, MD SUSTAIN 1 investigator and Chair of the Department of Diabetes, Endocrinology and Metabolism Billings Clinic, Billings, Montana MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Sorli: GLP-1 receptor agonists (GLP-1 RAs) have been found to be useful in the treatment of Type 2 diabetes with potent effects on blood glucose lowering while minimizing the risk of hypoglycemia and weight gain often seen with other classes of hypoglycemic agents. Semaglutide is a novel GLP-1RA that is currently in clinical development. The molecule shares 94% amino acid homology with native GLP-1 and has a half-life of approximately one week allowing for once weekly dosing. SUSTAIN 1 was designed to demonstrate superiority of semaglutide 0.5 mg and 1.0 mg once weekly over placebo in lowering HbA1c after 30 weeks of treatment. Additional secondary endpoints included weight loss versus placebo, percent of patients achieving HbA1c goals, percent of patients achieving 5% and 10% weight loss, and safety and tolerability.

What are the main findings? Dr. Petrie: Life expectancy estimates for those with type 1 diabetes allow gaps with the general population to be identified and improvements to be quantified. This research examined mortality for those with type 1 diabetes in Sweden from 2002 till 2011. The aim was to explore whether life expectancy of those with type 1 diabetes has improved in Sweden over the last decade and how any improvement compared with improvements seen in the general population. It found that for men with type 1 diabetes, the remaining life expectancy at age 20 increased significantly by about 2 years (from 47.7 in 2002–06 to 49.7 years in 2007–11) but for women with type 1 diabetes there was no significant change, with a life expectancy at age 20 of 51.7 years in 2002–06 and 51.9 years in 2007–11. There have been recent gains for both men and women from reductions in cardiovascular mortality however these gains were also seen in the general population which meant that the life expectancy gaps have stayed at about 11 years for men and 12 years for women over the last decade in Sweden.

VIC MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Magliano: This work shows  that Australians with type 1 diabetes had an estimated life loss of 11.6 years for men and 12.5 years for women compared with the general population. We saw no evidence of improvement in this over recent years. For those who are older with type 1, cardiovascular disease contributed substantially to the years of life lost in type 1 diabetes. Death before 60 years and mortality from endocrine and metabolic disease were also important contributors to the years of life lost in type 1 diabetes.

MedicalResearch.com Interview with: Ana Priscila Soggia Sirio Libanes Hospital, São Paulo, Brazil MedicalResearch.com: What is the background for this study? What are the main findings? Response: For many years, bariatric surgery is performed to treat class II and III obesity with diabetes remission in 80-90% of cases, related to weight loss and change in the secretion of intestinal factors that control blood glucose, like GLP-1 and GIP. In 2010, the International Diabetes Federation (IDF), proposed that diabetic patients with BMI between 30-35kg/m2 could be eligible, for bariatric surgery, in the case of no glycemic control with drug treatment. In this context, once glycemic control after bariatric surgery, was not related only to weight loss and also due to intestinal factors with physiological actions, the protocol was proposed. The objectives were to compare the clinical and surgical treatment in diabetics patients with class I obesity; and to compare the efficacy and security between two different surgical techniques. This study was developed and conducted by a research team from Sirio-Libanês Hospital in partnership with Ministry of Health through its philanthropic program PROADI. It is a clinical trial, with 42 class I obese diabetic type 2 patients with inadequate glycemic control that were randomized to tree arms: clinical treatment, gastric bypass surgery or sleeve with ileal transposition (sleeve-IT) surgery. The results showed that the sleeve-IT procedure is more effective for the treatment of diabetes in these patients compared with treatment with medication and with bypass surgery, currently considered the first choice of treatment. Among patients who underwent sleeve-IT, 100% achieved glycemic control after 1 year (HbA1c<6,5%) compared to 46% for bypass and 8% in the case of medication therapy. In addition, diabetes remission, that was defined as adequate glycemic control without any anti-diabetic medication, occured in 75% of sleeve-IT patients had versus 30% in bypass group.

Chiu[/caption] Ken C. Chiu, MD, FACE, FACP Professor Endocrinology Fellowship Training Program Department of Clinical Diabetes, Endocrinology, and Metabolism Diabetes and Metabolism Research Institute City of Hope National Medical Center Duarte, CA 91010-3000  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Chiu: The benefit of moderate alcohol consumption is well established in cardiovascular disease. However, the role of alcohol consumption in type 2 diabetes is less clear. We examined the role of alcohol consumption in type 2 diabetes using the data from the National Health and Nutrition Examination Survey 2005-1012, which is a representative US population. In the rare alcohol consumption group (< 12 drinks per year), 24.04% were diabetic while only 14.67% were diabetic in the moderate alcohol consumption (1-4 drinks per day) group (P><0.000001). In contrast, 21.05% were diabetic in the heavy alcohol consumption (≥ 5 drinks/day) group (P=0.003) when compared to the rare alcohol consumption group. Thus, in compared to the rare alcohol consumption, moderate alcohol consumption was associated with a lower risk of diabetes (OR: 0.72; 95%CI: 0.65-0.79) after adjustment for co-variates, while there was no benefit from heavy alcohol consumption (OR: 0.97; 95%CI: 0.90-1.05). Our study demonstrates that moderate alcohol consumption reduces the risk of diabetes by 28%.

What are the main findings? Dr. Farr: There are two main studies. In the first, we used immunohistochemistry to analyze 22 human brain tissue samples for the presence of GLP-1 receptors, which are protein molecules that respond to the GLP hormone’s signal. We found—for the first time—that GLP-1 receptors are expressed in the human brain, including the cortex, the part of the brain responsible for higher thought. Our second study was performed in 18 adults with type 2 diabetes. Participants received 17 days of either liraglutide, up to 1.8 milligrams, or a placebo (dummy drug) in a random order. Then after a three-week “washout” of no medication, the same participants received 17 days of the opposite treatment. Participants and investigators were unaware which treatment they received. On day 17 of each treatment, participants underwent brain scanning with functional magnetic resonance imaging (fMRI). During fMRI, participants viewed images of different foods. In response to highly desirable foods such as cake, pastries and fried foods, liraglutide decreased reward- and salience-related brain activations in the cortex compared with images of less desirable foods, such as fruits, vegetables and other low-calorie, low-fat foods.​

What are the main findings? Dr. Sheiner: The reported rates of gestational diabetes mellitus (GDM) are constantly escalating and little is known about the long term complications in the offspring. Evidence from the field of epigenetics strongly advocated the need for research on the neuropsychiatric impact of being exposed prenatally to GDM. In our study, in utero exposure to  gestational diabetes mellitus was found to be an independent risk factor for long term neuropsychiatric morbidity of the offspring.

MedicalResearch.com Interview with: Debbie Lawlor PhD School of Social and Community Medicine University of Bristol, Oakfield House, Oakfield Grove Medical Research Council Integrative Epidemiology Unit University of Bristol, UK and Rachel Freathy PhD, University of Exeter, Institute of Biomedical and Clinical Science, Royal Devon and Exeter Hospital,  Exeter  UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: A healthy birth weight is important for babies’ health and wellbeing in the first year of their life. It reflects how well the baby has grown and developed in the womb. The experience of fetuses in the womb and how well they grow and develop might also determine their future health, even into adulthood. Both being too light or too heavy at birth is not good for the baby. Lots of studies have shown that mothers who are fatter at the start of their pregnancy have babies who are more likely to be heavier. But is it not clear whether the mother being fatter causes their baby to be bigger at birth. If mothers’ fatness does cause their baby to be heavier at birth, why this happens is not clear. We used genes to find out whether being fatter in pregnancy causes babies to be born heavier. We also tested whether risk factors in the mother that are affected by her fatness, such as her blood pressure, and the level of glucose (sugar) and lipids (fats) in her blood stream affect how heavy her baby is. Our results showed that being fatter during pregnancy did cause a mothers’ baby to be born heavier. We also showed that having higher blood levels of glucose in pregnancy also caused a mothers’ baby to be heavier. But we did not find any effect of mothers’ blood levels of lipids in pregnancy on their baby’s weight. Whilst mothers who are heavier in pregnancy will tend to have higher blood pressure in pregnancy we found that higher blood pressure caused the women’s babies to be lighter.

What are the main findings? Dr. Shaw: Over the last decade or so, there has been a lot of research connecting obstructive sleep apnoea with type 2 diabetes. They co-exist very frequently in the same individual, they are both much more common in overweight and obese people than in people of healthy weights, both improve with weight loss, and both are associated with other conditions such as hypertension and heart disease. In addition, there has been evidence that some of the key abnormalities occurring in sleep apnoea (in particular, fragmented sleep and intermittent low oxygen levels) may have a direct effect on glucose metabolism, and increase blood sugar levels. This led many people to suspect that untreated sleep apnoea might be one reason that type 2 diabetes is hard to control, and that treating sleep apnoea in people with type 2 diabetes would improve their blood sugar control. We, therefore, undertook a large trial among people with type 2 diabetes, and previously unrecognised sleep apnoea, in which participants were randomised to either a group receiving specific treatment for sleep apnoea (continuous positive airways pressure, or CPAP, therapy at night) or to a control group. Over the six months of the trial, we saw no benefit of CPAP therapy in regard to blood sugar control (as measured by HbA1c). Even when we looked at sub-groups with worse blood sugar control at the start or worse sleep apnoea or who did the best in terms of using CPAP every night, there was still no sign of benefit on blood sugar control. We did, however, see some other benefits of CPAP therapy, with less daytime sleepiness, improvements in quality of life and lower diastolic blood pressure.

MedicalResearch.com Interview with: Dr. Zorana Andersen Department of Public Health Center for Epidemiology and Screening University of Copenhagen  MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Andersen: Diabetes is associated with increased risk of breast cancer, but exact mechanisms are unknown. The role of insulin has been debated. High mammographic density (MD) is one of the strongest predictors and a biomarker of breast cancer risk. Few studies have linked diabetes to mammographic density, finding none or weak inverse associations, but none had data on diabetes treatment. We examined whether diabetes and diabetes treatment are associated with mammographic density in a prospective cohort study of Danish women above age of 50 years. MedicalResearch.com: What should clinicians and patients take away from your report? Dr. Andersen: Women with diabetes, as well as clinicians working with diabetes and breast cancer and breast cancer screening, would have interest to know how different diabetes treatment can affect breast density, and hereby possibly breast cancer risk. For example, diabetic women taking insulin may possibly benefit from informing radiologists at breast cancer screening about their insulin use, due to increased breast density and increased risk of masking bias.

What are the main findings? Dr. Buse: Degludec is an longer acting basal insulin analog recently approved in the US.  Liraglutide is a once-daily GLP-1 receptor agonist.  Both are among the most powerful glucose lowering drugs available in the setting of type 2 diabetes.  They have very different properties.  Degludec is best at lowering fasting glucose. Liraglutide has effects on postprandial glucose as well.  The major side effects of degludec are hypoglycemia and weight gain. Liraglutide on the other hand has not an inherent effect to cause hypoglycemia and does promote weight loss.  Liraglutide does cause nausea and in fewer patients vomiting in a dose dependent manner. In developing the fixed dose combination the idea was to amplify glucose lowering efficacy and minimize the adverse effects of both components.  Prior studies have basically shown that this has been accomplished.  In this study we looked at the very common clinical scenario of the patient with type 2 diabetes inadequately controlled on basal insulin glargine and asked the question of whether switching from glargine to IDegLira (the combination product) would do better than continued titration of glargine.

What are the main findings? Response: It has long been known that all diabetes patients have elevated risk of cancer (10-15%). Patients on insulin slightly more (20-25%). Type 1 patients is only a small fraction (10%) of all diabetes patients, but they ALL take insulin. If insulin has a role in cancer occurrence it would be expected to be particularly pronounced in type 1 patients, and increasing by duration. But it is not, the risk of cancer is 15% elevated (if we disregard prostate, breast and other cancers only occurring in one of the sexes), and there is no increase in the excess risk by duration of insulin use. Breast cancer risk is 10% lower and prostate cancer risk some 40% lower. Overall there is very little increased cancer risk - 1% for men 7% for women.

Director, DRCRnet Coordinating Center Jaeb Center for Health Research Tampa, FL 33647 Adam Glassman[/caption] Adam Glassman, M.S. Director, DRCRnet Coordinating Center Jaeb Center for Health Research Tampa, FL 33647 Medical Research: What is the background for this study? What are the main findings? Response:  Diabetic macular edema (DME) involves a build-up of blood and fluid in the macula, the part of the eye needed for sharp, straight-ahead vision. Diabetic macular edema can occur in people with diabetic retinopathy and is the most common cause of diabetes-related vision loss.  Anti-VEGF agents are the first line treatment for most U.S. retinal specialists to treat vision loss from DME.  There are three commonly used agents to treat DME, EYLEA, Avastin, and Lucentis.  Eylea and Lucentis are FDA approved for Diabetic macular edema treatment.  However, Avastin is used off-label in repacked aliquots containing approximately 1/500th of the systemic dose used in cancer therapy.  The costs of these agents vary substantially, with Eylea priced at $1,850 per injection, Lucentis at $1,170, and repackaged Avastin at $60.  Results of this study, conducted by the Diabetic Retinopathy Clinical Research Network (DRCR.net) and funded by the NIH, found that all three agents are effective at improving vision and reducing DME over 2 years.  When vision loss is relatively mild at baseline (20/32-20/40), all three agents are similarly effective at improving visual acuity.  However, when vision loss at baseline is worse, Eylea outperforms Avastin at 2-years and also outperforms Lucentis at one year, but the difference between Eylea and Lucentis diminishes and is no longer statistically different at 2 years.  The percentage of participants that experienced a systemic adverse events such as heart attack, stroke, or death from an unknown cause was greater with Lucentis (12%) versus Eylea (5%) and Avastin (8%).  However, similar findings have not been seen in most previous studies.

We did a systematic review and meta-analysis of 49 studies, including almost 74 000 patients, to investigate the effect of treatment at different blood pressure levels. We found that treatment reduced the risk of death, stroke, myocardial infarction and heart failure if systolic blood pressure before treatment was above 140 mm Hg. However, if systolic blood pressure was below 140 mm Hg, treatment increased the risk of cardiovascular death.

Ob/Gyn, Neuroscience and Comparative Medicine Associate Chair for Faculty Development Dept Ob/Gyn and Reproductive Sciences Program in Cell Signaling and Neurobiology of Metabolism Yale University School of Medicine and Graduate School  Medical Research: What is the background for this study? What are the main findings? Dr. Diano: We have been studying the intracellular mechanisms that regulate glucose sensing by the brain. We found that in a specific area of the brain (called ventromedial nucleus of the hypothalamus) a small group of neurons (the brain cells) are able to sense increased glucose levels in the blood via their mitochondria, the energy powerhouse of the cells. This mitochondrial change enables these neurons to get activated, which in turn, results in a reduction of  glucose levels in the blood due to an increased muscles glucose utilization.

Nommsen-Rivers, PhD, RD, IBCLC Assistant Professor, UC Department of Pediatrics Cincinnati Children's Hospital Medical Center Dr. Laurie Nommsen-Rivers[/caption] Laurie A. Nommsen-Rivers, PhD, RD, IBCLC Assistant Professor, UC Department of Pediatrics Cincinnati Children's Hospital Medical Center  Medical Research: What is the background for this study? Dr. Nommsen-Rivers: Breastfeeding provides important benefits for mother and infant. Exclusive breastfeeding—that is, without any other food or fluids provided to the infant—is recommended for the first six months of life by multiple public health organizations. Some mothers, despite their best efforts, have difficulty establishing and sustaining sufficient milk production to support exclusive breastfeeding. Our previous research suggested that mothers with less optimal glucose tolerance are at risk for prolonged delays in time between birth and the establishment of copious milk production. We wanted to extend this finding by probing if mothers who had diabetes in pregnancy, as a sign of less optimal glucose tolerance, are at greater risk of sustained low milk production. “Glucose tolerance” refers to the body’s ability to metabolize glucose and maintain a healthy blood sugar level, which is orchestrated by the hormone insulin. For a long time, we did not consider insulin to play a role in milk production, but we are now learning that insulin plays an essential role in milk production.

What are the main findings?  Dr. Bowers: Autism spectrum disorder (ASD) affects approximately 1 in 68 children and the prevalence continues to rise. Past studies have suggested that conditions experienced by women during pregnancy (for example, obesity and gestational diabetes mellitus (GDM)) may be associated with having a child with ASD. We collected medical record data from patients who resided in the Cincinnati Children’s Hospital Medical Center’s primary catchment area and linked those data to data from birth certificates to identify metabolic risk factors. Two comparison groups were analyzed; one with developmental disabilities; and the other, controls without a reported ASD or other developmental disability. Descriptive statistics and regression analyses evaluated differences. We found that maternal obesity and  gestational diabetes mellitus were associated with an increased risk of Autism spectrum disorder in the offspring; however, no difference in risk of Autism spectrum disorder according to BMI and GDM was seen when comparing to the group with other developmental disabilities. The strongest observed association was the joint effect of obesity and GDM (compared to neither obesity nor GDM) :OR=2.53 (95% CI: 1.72, 3.73).

MedicalResearch.com Interview with: [caption id="attachment_21397" align="alignleft" width="160"]Mélanie Henderson, MD, FRCPC, PhD Mélanie Henderson[/caption] Mélanie Henderson, MD, FRCPC, PhD Pediatric Endocrinologist and Assistant Clinical Professor Division of Endocrinology and Diabetes University of Montreal/Centre Hospitalier Universitaire Ste-Justine Montréal, Québec Medical Research: What is the background for this study? What are the main findings? Dr. Henderson: Dysregulation in insulin sensitivity and insulin secretion are the basic elements in the pathophysiology of type 2 diabetes. There is extensive data suggesting that better lifestyle habits are associated with the prevention or the delay in onset of type 2 diabetes in adults, with improved lifestyle habits having been more effective than pharmacologic agents at diabetes prevention in one study. Little work however has been done to determine whether this holds true in children. Cross-sectional studies in youth have found conflicting results and no study has considered the combined effect of physical activity, fitness and sedentary behavior on insulin dynamics in children. Understanding the impact of lifestyle habits on insulin dynamics in childhood has become paramount, given that less than 7% of Canadian children are currently meeting physical activity guidelines and that 1/3 of school-aged Canadian children and 2/3 of Canadian teenagers are exceeding the current guidelines in terms of screen time, which advocate for a maximum of 2 hours daily. Our study shows that adiposity is the central predictor of insulin dynamics in children, and that physical activity and screen time play an important role, in part through their effect on adiposity. Thus, establishing and maintaining a highly physically active lifestyle early on in life, while minimizing sedentary behaviour (specifically screen time) appear to be important strategies to consider to prevent type 2 diabetes in youth.

MedicalResearch.com Interview with: Julianne van der Berg  PhD candidate Social Medicine Universiteitssingel Maastricht The Netherlands  Medical Research: What is the background for this study? What are the main findings? Response: The study investigated in data from The Maastricht Study, a large study in the Netherlands, associations of total duration and patterns of sedentary behavior with type 2 diabetes. We show that participants with type 2 diabetes spent the most time of day sedentary, 26 min more than participants without diabetes. Each additional hour of sedentary time was associated with a 22% increased risk of type 2 diabetes. Important is that these results were independent of high-intensity physical activity.

Assistant Professor of Surgery Ohio University Heritage College of Osteopathic Medicine Athens, Ohio 45701 Medical Research: What is the background for this study? Response: Half of the U.S. population has diabetes or prediabetes.  The rate is even higher in Appalachia.  As a society, we cannot sustain this level of disease.  It exacts a heavy toll on our productivity and our health care costs. Current approaches to diabetes, primarily with medication, are not sufficient.  More attention needs to be placed on the underlying cause of diabetes, and its traveling partners, overweight / obesity, heart disease and many common cancers.  That cause is our lifestyle.  Medical Research: What are the main findings? Response: As has been demonstrated in many other studies of lifestyle modification programs, chronic illnesses, like diabetes, can actually be reversed, and in some cases, even cured, by instituting a plant-based, whole food diet, increased physical activity and stress management techniques.  Our study reinforces that this is possible, even in a rural, poverty stricken region, when people are ready to make healthy changes.  Our study participants, on average, lost weight, and improved their blood sugar, lipid panel and blood pressure, by participating in The Complete Health Improvement Program (CHIP), a lifestyle medicine program.

Descriptive studies have so far either reported the prevalence of diabetes which is a snapshot of the percentage of people who have diabetes or the risk that people will develop diabetes in next 5 or 10 years. These estimates are not optimal since they overlook the risk of developing diabetes later in life. We calculated the lifetime risk of type 2 diabetes which is the risk that every person carries to develop type 2 diabetes up to end of his life. Moreover, we provided estimates for prediabetes, a high risk status that people experience before developing diabetes, and need for insulin therapy that might indicates severity of the disease. MedicalResearch.com: What are the main findings?  Dr. Dehghan: Our data suggest that the lifetime risk of developing prediabetes for a normoglycemic individual aged 45 years is one in two, and one in three nondiabetic individuals aged 45 years will develop diabetes. Three-quarters of individuals with prediabetes at age 45 years will eventually progress to diabetes, and half of the patients with diabetes at the same age will start insulin treatment. Stratification by BMI showed that normoglycemic people with healthy weight at age 45 years had a significantly lower prediabetes lifetime risk compared with overweight and obese individuals. Stratification by waist circumference showed similar effects on lifetime risks for diabetes in individuals with prediabetes. Similarly, in individuals with diabetes, the lifetime risk for insulin use among patients with diabetes was higher with increasing BMI and waist circumference.

MedicalResearch.com Interview with: Dr. Yanping Li Research Scientist Harvard T.H.Chan School of Public Health Boston, MA 02115

Medical Research: What is the background for this study? What are the main findings? Dr. Li: Sleeping difficulty is a common disorder but always lack of attention from both the patients and physicians. Our study finds that women with sleeping difficulty is associated with a higher risk of type 2 diabetes.

Abner PhD Sanders-Brown Center on Aging and Alzheimer's Disease Center College of Public Health, University of Kentucky Lexington, KY Dr. Erin Abner[/caption] MedicalResearch.com Interview with: Dr. Erin L. Abner PhD Sanders-Brown Center on Aging and Alzheimer's Disease Center College of Public Health, University of Kentucky Lexington, KY  Medical Research: What is the background for this study? What are the main findings? Dr. Abner: Diabetes is an important public health concern, and it has been linked to cognitive impairment and dementia, including dementia due to Alzheimer’s disease, in multiple studies of aging and cognition. Diabetes is considered by many to be a risk factor for Alzheimer’s disease, and there are many good reasons for scientists to have come to this conclusion. But, there are many brain diseases other than Alzheimer’s that cause dementia, and correctly identifying Alzheimer’s in a clinical patient can be deceptively difficult. When we looked at a very large sample of autopsied research volunteers (>2000 persons), we found that brain infarcts were more common among people with diabetes compared to people without, but Alzheimer’s pathology was about the same in both groups. Others have made this observation before, but in much smaller samples. Replicating this finding in a large sample is strong evidence that it is in fact cerebrovascular disease and not Alzheimer’s pathology that should be the primary concern among people with diabetes. In addition, we found that having diabetes was predictive of worsened global cognition at the end of life.

Correll, MD Professor of Psychiatry and Molecular Medicine Hofstra Northwell School of Medicine Hempstead, New York, USA Investigator, Center for Psychiatric Neuroscience Feinstein Institute for Medical Research Manhasset, New York, Medical Director, Recognition and Prevention The Zucker Hillside Hospital, Department of Psychiatry  Medical Research: What is the background for this study? Dr. Correll: Antipsychotics have been used increasingly for psychotic, but also for many non-psychotic conditions, including for disorders and conditions for which they have not received regulatory approval. Moreover, antipsychotics have been associated with weight gain and abnormalities in blood fat and blood glucose levels. Although data in youth have been less available than in children and adolescents, youth appear to be more sensitive to the cardiometabolic adverse effects of antipsychotics than adults in whom significant weight gain might have already occurred due to long-term prior antipsychotic treatment. Nevertheless, type 2 diabetes, which is related to weight gain, overweight and obesity, seemed to be more common in adults than youth, likely due to the fact that it takes a long time for the body to develop diabetes. Recently, several individual epidemiologic or database studies with sufficient long-term follow-up durations suggested that the type 2 diabetes risk was higher in youth exposed to antipsychotics than healthy control youth and, possibly, even compared to psychiatrically ill patients treated with non-antipsychotic medications. However, a meta-analytic pooling of all available data has not been available to estimate the absolute and relative risk of type 2 diabetes in youth receiving antipsychotic treatment.  Medical Research: What are the main findings? Dr. Correll: The main findings of the study that meta-analyzed data from 13 studies with 185,105 youth exposed to antipsychotics (average age 14.1 and 59.5 percent male) are that the absolute rates of type 2 diabetes are fortunately still relatively low, i.e. a cumulative type 2 diabetes  risk of 5.7/1,000 patients and an exposure adjusted incidence rate of 3.1/1,000 patient-years. Nevertheless, the cumulative risk of type 2 diabetes and its exposure adjusted incidence rate per patient were 2.6 times and three times higher compared with 298,803 healthy controls. Furthermore, the cumulative risk of type 2 diabetes and its exposure adjusted incidence rate per patient were 2.1 times and 1.8 times higher compared with 1,342,121 psychiatric patients not exposed to antipsychotics. Main modifiable risk factors for type 2 diabetes development in antipsychotic-treated youth were treatment with the antipsychotic olanzapine and longer antipsychotic exposure time.

[caption id="attachment_20536" align="alignleft" width="158"]Cuilin Zhang MD, PhD Senior Investigator, Epidemiology Branch Division of Intramural Population Health Research NICHD/National Institutes of Health Rockville, MD 20852 Dr. Cuilin Zhang[/caption] MedicalResearch.com Interview with: Cuilin Zhang MD, PhD Senior Investigator, Epidemiology Branch Division of Intramural Population Health Research NICHD/National Institutes of Health Rockville, MD 20852  Medical Research: What is the background for this study? What are the main findings? Dr. Zhang: Potatoes are the third most commonly consumed food crop in the world. In the United States, about 35% of women of reproductive age consume potatoes daily, accounting for 8% of daily total energy intake.  Gestational diabetes mellitus (GDM) is a common complication of pregnancy characterized by glucose intolerance with onset or first recognition during pregnancy. GDM is at the center of a vicious circle of 'diabetes begets diabetes' across generations. Potato foods are typically higher in glycemic index and glycemic load, but data are lacking regarding whether potato consumption is associated with the risk of Gestational diabetes mellitus. Medical Research: What is the background for this study? What are the main findings? Dr. Zhang: Women who eat more potatoes before pregnancy may have higher risk of gestational diabetes—the form of diabetes that occurs or first diagnosed during pregnancy—compared to women who consume fewer potatoes. Substituting potatoes with other vegetables, legumes or whole grains may help lower gestational diabetes risk.
