MedicalResearch.com: What is the background for this study? What are the main findings?Response: In Japan, we have a health checkup system for middle and elderly people to prevent their non-communicable diseases (NCDs) including the Metabolic Syndrome (MetS) and give them some health guidance based a guideline. The guideline has suggested that short duration between bed time and dinner time will be a risk factor of metabolic syndrome or diabetes mellitus for some duration.
However, there may be no association between them, it is the main findings.(more…)

MedicalResearch.com: What is the background for this study? Response: Before rotavirus vaccines were available, rotavirus infection was the most common cause of severe gastroenteritis in infants and young children. Because it is so contagious, infection in childhood is thought to be universal in unvaccinated children.
Previous studies indicated that rotavirus infection of infants might be an environmental promoter of type 1 diabetes. Therefore, we anticipated that the introduction of the rotavirus vaccine might alter the disease incidence in young children.(more…)

MedicalResearch.com: What is the background for this study? What are the main findings?Response: As a dermatologist, we see many patients with newly diagnosed with bullous pemphigoid (BP), many of whom have diabetes.
The use of DPP-4 inhibitors is a common treatment for diabetes, we have noted previous case reports that DPP-4 inhibitors may be the cause of BP. For this reason, we started this study.
The most important thing in my article is DPP-4 inhibitors, particularly vildagliptin, may be associated with the development of bullous pemphigoid in male patients with diabetes. We have confirmed these points based on the nationwide, population-based study. It is very meaningful because there have been few studies using large sample sizes so far.

MedicalResearch.com: What is the background for this study? What are the main findings?Response: The prevalence of young onset diabetes (YOD) is increasing world-wide with doubling of its prevalence in the last 10 years in many developed nations. Using the Hong Kong Diabetes Register established since 1995, we first reported that 1 in 5 Chinese adults with diabetes were diagnosed before the age of 40 years. These young patients had poor control of multiple risk factors with 1.5 fold higher risk of premature death and cardiovascular-renal complications compared to patients with usual onset of diabetes after the age of 40 (Chan JC et al AJM 2014, Luk A et al Diabetes Care 2014). Due to the multisystem nature of diabetes, we asked the question whether these young patients might have recurrent hospitalizations during their 3-4 decades of complex clinical course.
Using a territory-wide diabetes database involving 0.42 million people followed up between 2002 and 2014, we compared the hospitalization rates accrued till the age of 75 years and found that patients with young onset diabetes had the highest hospitalization rates by attained age. Compared to patients with usual onset of diabetes, patients with YOD had 1.8- 6.7 higher risk of hospitalizations due to all-causes, notably renal disease compared to those with usual onset of disease.
Amongst patients with young onset diabetes, over one-third of the bed-days were due to mental illness before the age of 40 years. We used mathematical modeling and estimated that intensified risk factor control in YOD can reduce the cumulative bed-days by 30% which can be further reduced by delaying the onset of diabetes. These original data is a wakening call to the community regarding the complex nature of YOD involving interactions amongst environment, lifestyles and personal factors (e.g. genetics, education and socioeconomic status) and the biomedical-psychological-behavioral needs of these high risk population, which if undiagnosed, untreated or suboptimally managed, can have huge economic impacts on health care system and loss of societal productivity, leaving personal suffering aside.

MedicalResearch.com: What is the background for this study? Response: More and more patients suffered from diabetes mellitus (DM) around the world, as well diabetic complications such as diabetic retinopathy (DR). DR is one of the major causes of blindness in working-age adults. In addition to the cost of treatment for patients with advanced DR, loss of visual function also yields a great burden to the family and society. For advanced DR, surgical interventions such as retinal laser, intravitreal injection, and vitrectomy are needed. However, those surgical interventions for severe DR can only retard or stop disease progression. If DR can be prevented or slowed by medical treatments, the burden of medical costs for treating severe DR may be decreased.
Statin, an HMG-CoA reductase inhibitor, was discussed frequently in the recent years. Multiple functions of statins besides their lipid lowering effect were discovered. Previous investigations have reported that statin therapy could reduce mortality rate and decrease risk of cardiovascular diseases.
In our study, we wanted to figure out if statin therapy may have any association between diabetic retinopathy.(more…)

MedicalResearch.com: What is the background for this study? What are the main findings?Response: Migraine has further been associated with increased risk of overall and specific cardiovascular disease events.
Because migraine has also been associated with factors related with insulin resistance and type 2 diabetes, an association between migraine and diabetes has been hypothesized.
We observed a lower risk of type 2 diabetes in women with active migraine.
We also show a linear decrease of migraine prevalence long before and a plateau long after type 2 diabetes diagnosis.(more…)

MedicalResearch.com: What is the background for this study? Response: Shift work has progressed in response to changes in economic pressure and greater consumer demand for 24-hour services. There are many economic advantages to increased shift work, including higher employment, increased services to customers, and improved trade opportunities. Currently, one in five employees in the U.S. works nonstandard hours in the evening, night, or rotating shifts. However, shift work, especially night shift work, has been associated with a higher risk of chronic diseases, including type 2 diabetes, cardiovascular disease, and several types of cancer.
Compelling evidence has shown that body weight and lifestyle behaviors, such as smoking, diet, and physical activity can influence type 2 diabetes risk. Among shift workers, excess adiposity and increased smoking are frequently and consistently reported, whereas the evidence on physical activity and diet is mixed. Additionally, no previous study has examined the joint associations of rotating night shift work duration and unhealthy lifestyle factors with risk of type 2 diabetes, or evaluated their potential interactions.
Therefore, we prospectively assessed the joint association of rotating night shift work and established type 2 diabetes lifestyle risk factors with risk of type 2 diabetes and quantitatively decomposed the proportions of the joint association to rotating night shift work alone, to lifestyle alone and to their interaction in two large US cohorts.

MedicalResearch.com: What is the background for this study? What are the main findings?Response: Elevated cholesterol (specially low density lipoprotein) has been causally linked to the development of coronary artery disease whereas the causal relationship between obesity and cardiovascular disease has remained controversial. This is important because of increasing epidemic of obesity and metabolic syndrome. Mendelian randomization studies provide one way of determining a causal association where we can look at the outcomes of individuals stratified by the presence or absence of a particular allele. Since these alleles are randomly distributed in the population of interest, this is "nature's randomized trial" in that the particular allele is naturally distributed and hence minimal risk of bias.
In other words, lets say that I hypothesize that a particular gene "A" is linked with coronary artery disease. If the given gene is indeed causally linked with coronary artery disease, patients with activation of that gene should have significantly greater risk of developing coronary artery disease.
Based on these principles, we conducted a systematic review and meta-analysis of the available evidence and found that the risk of developing coronary artery disease and diabetes is significantly increased with obesity. Although hypothesis generating, we think that these findings may suggest a causal association between obesity and cardiovascular disease.(more…)

MedicalResearch.com: What is the background for this study? What are the main findings?Response: Cannabis use is increasing in Colorado and many patients with type 1 diabetes (which is an autoimmune form of diabetes that requires life insulin therapy) are using cannabis. Therefore, we surveyed adult patients with type 1 diabetes to study the association between cannabis use and glycemic control and diabetes acute complications (such as diabetic ketoacidosis) in adults with type 1 diabetes.
Main findings of the study: The risk for diabetic ketoacidosis (a serious condition where body produces high levels of acids called ketones in patients with diabetes) was two times higher among adults with type 1 diabetes who reported using cannabis in the past 12 months compared to adults with type 1 diabetes who reported not using cannabis.

MedicalResearch.com: What is the background for this study? Response: In previous studies, the disorganization of retinal inner layers (DRIL) has demonstrated its ability to help determine visual acuity (VA) prognosis in diabetic macular edema that requires treatment. Given this association, the research group at Cole Eye Institute studied how DRIL may affect VA outcomes in patients with retinal vein occlusion (RVO) undergoing treatment for secondary macular edema.
DRIL is defined as the extent to which there is a failure in the recognition of any of the demarcations between the ganglion cell-inner plexiform layer complex, inner nuclear layer, and outer plexiform layer on optical coherence tomography (OCT).

Scott David Solomon, MD
Director, Noninvasive Cardiology

Brigham and Women's HospitalMedicalResearch.com: What is the background for this study? What are the main findings?Response: The sodium glucose transport proteins are known to be important in regulating uptake of glucose. SGLT-1 is predominantly located in the gut and is responsible for uptake of glucose and galactose in the small intestine. Individuals born with severe mutations of this gene have severe malabsorption syndrome.
We looked at genetic variants that lead to reduced function of the protein, but not complete loss of function, in a large cohort of individuals in the NIH funded Atherosclerosis Risk in Communities Study. We found that those with mutations in the gene had reduced glucose uptake, as measured by an oral glucose tolerance test, as well as less obesity, diabetes, heart failure and death.

MedicalResearch.com: What is the background for this study? What are the main findings?Response: In a large population of pregnant women, we found that the risk of the offspring being diagnosed with type 1 diabetes before the age of 15.6 years (the follow up period) was doubled in the group of women ingesting the highest amounts of gluten (20-66 g/day) versus the group of women ingesting the lowest amounts of gluten (0-7 g/day). For every additional 10 grams of gluten ingested, the risk for type 1 diabetes in the child increased by a factor of 1.31.
It the sense that it was a hypothesis that we specifically tested, we were not surprised. We had seen in animal experiments that a gluten-free diet during pregnancy protected the offspring from diabetes, and we wanted to see if we could prove the same pattern in humans. There could be many reasons why we would not be able to show the association, even if it was there (sample size, low quality data, covariates we could not correct for and so on), but we were off course pleasantly surprised that we found the association that we were looking for, in particular because it is quite robust (more…)

MedicalResearch.com: What is the background for this study? What are the main findings?
Drugs that enhance the breakdown of circulating triglycerides by activating lipoprotein lipase (LPL) are in pre-clinical or early-clinical development.
It is not known if these drugs will reduce heart attacks or diabetes risk when added to the current first line therapies (statins and other cholesterol-lowering agents).
Studying this would require large randomised controlled trials, which are expensive (millions of GBPs) and time-consuming (years).
Human genetic data can be used to provide supportive evidence of whether this therapy is likely to be effective by “simulating” a randomised controlled trial.
Our study used naturally occurring genetic variants in the general population (study of ~400,000 people) to address this.
Individuals with naturally-lower cholesterol due to their genetic makeup were used as model for cholesterol-lowering therapies (eg. Statins).
Individuals with naturally-lower triglycerides due to genetic variants in the LPL gene were used as model for these new triglyceride-lowering therapies.
We studied the risk of heart attacks and type 2 diabetes in people in different groups.

MedicalResearch.com: What is the background for this study? Response: The Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study showed that higher levels of a mother’s blood sugar during pregnancy are associated with higher risks of increased birthweight, fatter babies, delivery by Cesarean Section, low blood sugar in newborn babies and high levels of insulin in the cord blood at birth.
It is not clear whether levels of a mother’s blood sugar during pregnancy are associated with risk obesity later in life as is known to occur in offspring or pre-existing maternal diabetes mellitus. With funding from the National Institutes of Health, the HAPO Follow Up Study addressed this in a subset of nearly 5,000 mothers and their children from the original HAPO Study 10-14 years later (average 11.4 years).

MedicalResearch.com: What is the background for this study? What are the main findings?Response: The Developmental Origins of Health and Disease (DOHaD) hypothesis proposes that cardiovascular diseases and other chronic conditions in adulthood may be a consequence of an unfavorable intrauterine life, a relationship that is further modified by patterns of postnatal growth, environment, and lifestyle.
Based on the two large-scale cohort studies, the Shanghai Women’s Health Study and the Shanghai Men’s Health Study, we observed nonlinear associations for birth weight with baseline body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR), and low birth weight was linked with lower BMI, smaller WC, but larger WHR and WHtR.
An excess risk of T2DM and hypertension was observed for low birth weight (<2500 g) versus birth weight of 2500-3499 g since baseline and since birth. The results support the DoHad hypothesis, and indicate the importance of nutrition in early life on health in Chinese population.(more…)

MedicalResearch.com: What is the background for this study? What are the main findings?Response: Type 1 diabetes (T1D) is a major health problem affecting over 1.25 children and adults in the United States alone. It also affects our beloved companion animals, with 1 out of every 100 dogs and cats having this condition.
T1D results from an autoimmune condition, where the patient’s body, by mistake, attacks and destroys cells in the pancreas (β cells) that are responsible for regulating blood glucose levels by producing insulin. While injectable insulin represents the standard of care for these patients, it provides an inferior control system relative to functional β cells, leaving the majority of patients at risk for life-threatening complications. Although transplantation of pancreatic islets, which contain replacement β cells, via portal vein injection into the liver, is an attractive therapeutic alternative for these patients, persistent risks and challenges preclude its more widespread clinical adoption. These include rapid destruction and loss of function of the majority of donor cells upon transplantation and the need for life-long immunosuppression.
This study evaluated a novel packaging strategy for the delivery and maintenance of functional donor islets beneath the skin, resulting in rapid and extended reversal of T1D in diabetic mice.(more…)

MedicalResearch.com: What is the background for this study? What are the main findings?Response: More than 9 percent of adult Americans—about 30 million people—are estimated to have type 2 diabetes, according to the American Diabetes Association. The disease tends to worsen over time, with blood sugar levels rising along with the risks of developing large blood vessel (macrovascular) complications like heart attack and stroke, as well as small blood vessel (microvascular) complications affecting the nerves of the feet and hands (neuropathy), kidneys (nephropathy), and eyes (retinopathy).
Among more than 4000 patients who underwent bariatric surgery, the 5-year incidence of microvascular disease — including neuropathy, nephropathy, and retinopathy — was nearly 60% lower than that of 11,000 matched nonsurgical control patients receiving usual diabetes care.(more…)

MedicalResearch.com: What is the background for this study? Response: Patients with type 2 diabetes have 2 to 4 times greater risk for death and cardiovascular events compared to the general population. There are several randomized trails that encourage a range of interventions that target traditional and modifiable risk factors, such as elevated levels for glycated hemoglobin, blood pressure and low-density lipoprotein cholesterol to reduce the risk for complications of type 2 diabetes. However, there are few randomized trails that have investigated the effects of multifactorial risk factor intervention in reducing the risk for death and cardiovascular events, as compared to patients that are treated with usual care.
We set out to investigate the extent to which the excess risk associated with type 2 diabetes may be mitigated or potentially eliminated by means of evidence-based treatment and multifactorial risk factor modification. In addition, we estimated the relative importance between various risk factors and the incremental risk of death and cardiovascular events associated with diabetes. Furthermore, we investigated the association between glycated hemoglobin, systolic blood pressure and low-density lipoprotein cholesterol (LDL-C) within evidence based target ranges and the abovementioned outcomes.

What are the main findings?Response: The rationale for this study comes from evidence that patients with PTSD are more likely to be obese than persons without PTSD and have more difficulty losing weight.
Given the obesity epidemic and substantial role of obesity in risk of type 2 diabetes, we sought to determine if obesity accounted for the existing evidence that PTSD is a risk factor for incident type 2 diabetes. Other studies have adjusted for obesity or BMI in models that control for obesity/BMI and other confounders simultaneously which prohibits measuring the independent role of obesity on the ass (more…)

Considering the rapid and substantial increase of diabetes prevalence, identifying modifiable risk factors is of major importance. In this regard, long work hours have recently been linked with diabetes, but more high-quality prospective studies are needed. Our study evaluated the relationship between long work hours and the incidence of diabetes among 7065 workers over a 12-year period in Ontario, Canada.

MedicalResearch.com: What is the background for this study? Response: Human endogenous retroviruses (HERVs), remnants of ancestral viral genomic insertions, are known to represent 8% of the human genome and are associated with several pathologies. In particular, the envelope protein of HERV-W family (HERV-W Env) has been involved in multiple sclerosis pathogenesis.
A previous study published in JCI Insight revealed that HERV-W Env is also involved in Type 1 diabetes (T1D) pathogenesis. In this study, we observed that HERV-W-Env protein and RNA are detected respectively in sera and peripheral blood mononuclear cell (PBMC) of T1D patients.
We also demonstrated that this pathogenic protein is expressed by acinar cells in human T1D pancreas and is associated with the recruitment of macrophages within the pancreas of these patients. HERV-W Env also displays direct pathogenic properties as it inhibits insulin secretion by human islets of Langerhans.

Would you briefly outline the essentials of the Optifast plan?Response: OPTIWIN is a year-long, multi-center, open-label, randomized, head-to-head study. It was designed to evaluate the effectiveness of the medically-monitored, meal replacement OPTIFAST Program on weight loss and maintenance, in comparison with a standard-of-care, food-based diet among adults with a BMI higher than 30 kg/m2.
Nestlé Health Science’s OPTIFAST Program combines proven essential features of weight loss success ‒ medical monitoring, nutrition education, exercise guidance, in-person support, full meal replacement and behavior modification. With OPTIFAST meal replacement products, the program gives patients the prescribed amount of calories and micronutrients each day. It is a non-surgical option designed for people with a Body Mass Index (BMI) greater than 30, and is available in more than 400 weight loss clinics nationwide.
The Program is comprised of three core phases ‒ active weight loss (during which total diet replacement is used), transition to self-prepared ‘everyday’ meals and maintenance. Clinical supervision is a key component of the program as it helps assess progress towards better health and emotional well-being.

MedicalResearch.com: What is the background for this study? Response: People with type 1 diabetes (T1D) are confronted often with the inability to achieve satisfactory glycemic control, being good HbA1c, but in particular stable glycemic control, avoiding hyperglycemic events, but also hypoglycemic events, despite novel insulins and novel technologies. Moreover, intensive insulin therapy is often associated with weight gain, leading to an increase in overweight and obesity also in people with T1D. All of these issues affect quality of life.
In the DEPICT 2 study we examined the impact of adding a selective SGLT2 inhibitor, dapagliflozin (two doses tested – 5 and 10mg) in a double blinded manner versus placebo to background insulin (MDI or CSII) in people with T1D reaching insufficient glycemic control (HbA1c 7.5-10.5%). Primary endpoint was lowering in HbA1c at 24 weeks and secondary endpoints included insulin dose reduction and weight reduction as well as a composite endpoint of having a HbA1c drop of >=0.5% without severe hypoglycemia. The study ran internationally, with about 1/3 of patients coming from North America, 1/3 from Europe and 1/5 from Asia (Japan).

MedicalResearch.com: How would you briefly explain the most important findings and conclusions of this study to a non-expert?
The type-2 diabetes (T2D) epidemic will affect over 642 million people worldwide by 2040. As a result, diabetes costs the US healthcare over $174 billion dollars annually and is the leading cause of blindness, amputations, renal failure, and poor cardiovascular outcomes. Recently, bariatric surgery, bypassing stomach and intestine from the food stream, has shown promising results and shown to be superior to pharmaceuticals in managing T2D. However, the risks of surgery along with permanent changes to gastrointestinal anatomy deters many suitable patients from surgery, with less than 1-2% of Americans who qualify for weight loss surgery actually undergoing the procedure. Therefore, there is an urgent need for a safe, non-invasive and effective treatment for wider diabetic patient population.
We envisioned a pill that a patient can take before a meal that transiently coats the gut to replicate the effects of surgery. During the past 8 years, we’ve been working on this idea and have developed a safe gut-coating material that can potentially mimic the beneficial effects of gastric bypass procedures in the form a pill.
LuCI can be activated in any part of gastrointestinal tract (e.g. stomach, duodenum, intestine, colon) to form a temporary physical barrier that isolates that part of gastrointestinal tract. In our pre-clinical models, LuCI coated the duodenum to modulate glucose responses in oral glucose tolerance tests.
These beneficial effect are observed without any evidence of systemic absorption of the drug.
We believe that LuCI could be a new therapeutic approach for T2D that is based on Roux-en-Y gastric bypass surgery, but is safer, associated with significantly less complications, and thus can potentially help a wide T2D patient population.
In a separate set of studies, we also showed that luCi allows delivery of certain proteins and drugs, which would normally be degraded by the gastric acid, to the GI tract, protecting it from gastric acid digestion and prolonging their luminal exposure.

An example of one HEDIS performance measure we looked at was percentage of patients with diabetes that had twice annual HbA1c testing. The key findings of the paper are that physicians who maintained their certification had better scores on 5 of 6 HEDIS performance measures than similar physicians who did not maintain their certification.
