MedicalResearch.com Interview with: C Raina Elley C Raina Elley Associate Professor and General Practitioner, Acting Head, Dept General Practice & Primary Health Care, Faculty Medical and Health Sciences, University of Auckland, Private Bag 92019, Auckland, New ZealandAssociate Professor and General Practitioner, Acting Head, Dept General Practice & Primary Health Care, Faculty Medical and Health Sciences, University of Auckland, Private Bag 92019, Auckland, New Zealand MedicalResearch.com: What are the main findings of the study? Answer: Type 2 Diabetes is the leading cause of end-stage renal failure and dialysis in many countries. Early identification of those who are at risk within primary care could prompt more intensive intervention to control glycaemia and blood pressure and use of ACE inhibitors or angiotensin receptor blockers to slow progression. Traditionally estimated glomerular filtration rate and/or urine albumin creatinine ratio have been used to alert clinicians of deteriorating renal function in people with diabetes. However, a far more accurate renal risk score has been developed that combines serum creatinine, demographic characteristics, albuminuria, glycaemia, blood pressure, cardiovascular co-morbidity and duration of diabetes. The 5-year renal risk score was developed by following more than 25,000 people with type 2 diabetes in New Zealand for a median of 7.3 years (equivalent to 180,497 person-years). The study identified those who commenced dialysis for end-stage renal disease, received a renal transplant or died from renal failure to derive the risk score. (more…)

MedicalResearch.com:  Interview with Christina Ellervik Associate Professor Faculty of Health and Medical Sciences University of Copenhagen , Denmark MedicalResearch.com: What are the main findings of the study? Answer: Early measurement of transferrin saturation leading to early intervention in patients with late-onset type 1 diabetes improves life expectancy. Excess death is mainly due to cancer-specific death. (more…)

Changes in Red Meat Consumption and Subsequent Risk of Type 2 Diabetes Mellitus: Three Cohorts of US Men and Women MedicalResearch.com: What are the main findings of the study? Answer: -- Compared with people who did not change their intake of red meat, those who increased it by as little as half a serving a day (about 1.5 ounces) over a four-year period had a 48% increased risk of developing type 2 diabetes in the subsequent 4 years. -- People who decreased their intake by half a serving a day over four years did not have an acute reduced risk in the next four years compared to people who did not change their intake, but had a reduced risk of developing the disease by 14% in the entire follow-up period, suggesting a prolonged effect. -- The findings included both processed meat such as lunch meat and hot dogs and unprocessed meats such as hamburger, steak and pork. And the association was generally stronger for processed red meat compared to unprocessed red meat. -- Adjusting for weight modestly reduced the association between red meat consumption and diabetes suggesting that weight gain played a role in the development of the disease.

MedicalResearch.com Interview with:  Dr. Ezio Bonifacio, Ph.D. Professor, Preclinical Stem Cells/Diabetes Center for Regenerative Therapies Dresden Technische Universität Dresden MedicalResearch.com:  What are the main findings of the study? Dr. Bonifacio: Children who develop multiple islet autoantibodies are destined to develop diabetes. Only a minority will be diabetes-free 15 years after developing islet autoantibodies. This is regardless of whether they have a family history of type 1 diabetes. Progression to diabetes after seroconversion varied from weeks to decades, and 20% of children had diabetes within 2 years from seroconverting. Progression was fastest in children who developed their islet autoantibodies before age 3 years. MedicalResearch.com:  Were any of the findings unexpected? Dr. Bonifacio: Unexpected is probably not the right word. The Eisenbarth model of chronic disease proposes that diabetes will happen some time after autoimmunity and the findings show the reality of it. Perhaps the unexpected finding is that it is not always chronic and that for a number of children, intervention would need to be applied quickly. (more…)

Martin Sénéchal, Ph.D. Postdoctoral Researcher The Manitoba Institute of Child Health University of Manitoba 511E- 715 McDermot Ave Winnipeg, ManitobaMedicalResearch.com eInterview with Martin Sénéchal, Ph.D. Postdoctoral Researcher The Manitoba Institute of Child Health University of Manitoba 511E- 715 McDermot Ave Winnipeg, Manitoba MedicalResearch.com: What are the main findings of the study? Answer: The main finding of this study is that reducing central adiposity and increasing fitness in men and women with Type 2 diabetes are key components for successfully improving glycemic control. A secondary finding of the study is that improvement in both central adiposity (reduction) and fitness (increasing) simultaneously; increase the likelihood of reducing HbA1c, one of the most widely used indicators of glucose control, and/or Type 2 diabetes medications.

MedicalResearch.com eInterview with Iris Shai, RD, PhD PI of the DIRECT trial Ben Gurion University of the Negev, Israel MedicalResearch.com: What are the main findings of the study? Dr. Shai: Low-carbohydrate is as effective as Mediterranean or low-fat diets in improving renal function among moderately obese participants with or without type 2 diabetes, with baseline serum creatinine<176µmol/L (not sever renal stage).  The effect is likely to be mediated by weight-loss induced improvements in insulin sensitivity and blood pressure.

This interview content is written by Dr Dae-Kyu Song, the corresponding and responsible author of the manuscript shown at “Park, Jae-Hyung et al. (2013). Green tea extract with polyethylene glycol-3350 reduces body weight and improves glucose tolerance in db/db and high-fat diet mice. Naunyn-Schmiedeberg’s Archives of Pharmacology. DOI 10.1007/s00210-013-0869-9“. Dr Jae-Hyung Park is the first author of the manuscript and a graduate student of Dr. Dae-Kyu Song MedicalResearch.com: What are the main findings of the study? Answer: At doses which could be achieved by drinking green tea on a daily basis, it has been known that green tea extract (GTE) inhibits intestinal glucose and lipid absorption when it is present in the intestinal tract. It is a reason why green tea consumption has been known to be beneficial for controlling obesity and type 2 diabetes. However, we have found that, after the intestinal absorption of GTE itself, the circulating GTE can elevate blood glucose levels by blocking cellular glucose uptake in most tissues, thereby limiting glucose utilization of the tissues. Therefore, we have tried to prolong the residence time of GTE in the intestine and block the intestinal absorption of GTE, by adding non-toxic polymer polyethylene glycol (PEG) to GTE. As a result, in 4 week treatment, the GTE+PEG regimen dramatically helps obesity-induced diabetic mice lose body weight and ameliorate glucose intolerance. Interestingly, GTE alone is without any effect. (more…)

MedicalResearch.com: What are the main findings of the study? Dr. Franco: Population wide weight loss of about 5 kg was related with large decreases in diabetes and cardiovascular mortality. On the contrary, Body weight regain was related with an increase in diabetes prevalence, incidence, and mortality, as well as a deceleration in the previously declining rates of cardiovascular death.

Dr. Ciaran McMullan MD from Channing Division of Network Medicine in Boston, a research division within the Department of Medicine at Brigham and Women’s Hospital, Boston MassMedicalResearch.com Interview with Dr. Ciaran McMullan MD from Channing Division of Network Medicine in Boston, a research division within the Department of Medicine at Brigham and Women’s Hospital, Boston Mass MedicalResearch.com: What are the main findings of the study? Dr. McMullan: In this observational study performed in non-diabetic women we found that lower nocturnal melatonin secretion predicted future risk of developing type 2 diabetes. When we categorized the individuals by category of nocturnal melatonin secretion we found that those in the lowest category had twice the risk as those in the highest category of nocturnal melatonin secretion. This association remained even after adjusting for other well established risk factors for development of diabetes including body mass index, physical activity, dietary factors, family history of diabetes, smoking and hypertension. This increased risk translates into the lower melatonin secretion group having an additional 5 cases of incident diabetes per 1000 person years than the high melatonin secretion group. (more…)
