MedicalResearch.com Interview with: Niels Graudal, MD, DrMSc Senior Consultant Department of Internal medicine/Infectious Medicine/Rheumatology IR4242 Copenhagen University Hospital, Rigshospitalet Denmark Dr. Graudal: There are no studies, which show what happens with the risk of cardiovascular death or mortality if you change your sodium intake. Our study shows the association of sodium intake as it is with cardiovascular disease and mortality, which is only the second best way to consider the problem, but as the best way does not exist we have accepted this approach. There have been two different assumptions concerning the risks of sodium intake. One is that there is an increasing risk of heart disease, stroke and death of salt intake above 2300 mg, and one is that salt is not dangerous at all. Our study shows that both positions partially may be true, as a salt intake above 4900 mg is associated with increased risk of cardiovascular disease and mortality, whereas the present normal salt intake of most of the world’s populations between 2300 mg and 4900 mg is not associated with any increased risks. In addition our study shows that a low sodium intake below 2300 mg is also associated with increased risk of cardiovascular disease and death. (more…)

Jill Cameron, PhD M.Ed., B.Sc. O.T CIHR New Investigator, Associate Professor, Department of Occupational Science and Occupational Therapy Graduate Department of Rehabilitation Science Faculty of Medicine, University of Toronto Adjunct Scientist, UHN-Toronto Rehabilitation InstituteMedicalResearch.com Interview with: Jill Cameron, PhD CIHR New Investigator, Associate Professor, Department of Occupational Science and Occupational Therapy Graduate Department of Rehabilitation Science Faculty of Medicine, University of Toronto Adjunct Scientist, UHN-Toronto Rehabilitation Institute MedicalResearch.com: What are the main findings of the study? Dr. Cameron: In our study with 399 stroke survivor, caregiver dyads, caregivers reported more psychological wellbeing when they provided more assistance to stroke survivors who had fewer symptoms of depression, better cognitive functioning, and who had more severe strokes.  In addition, caregivers who maintained participation in valued activities, had more mastery, gained personally providing care, were in better physical health, and were older reported more psychological wellbeing.

Erica P. Gunderson, PhD, MS, MPH Senior Research Scientist, Cardiovascular and Metabolic Section Division of Research, Kaiser Permanente Northern California Oakland, CA 94612-2304MedicalResearch.com Interview with: Erica P. Gunderson, PhD, MS, MPH Senior Research Scientist, Cardiovascular and Metabolic Section Division of Research, Kaiser Permanente Northern California Oakland, CA 94612-2304 MedicalResearch.com: What are the main findings of the study? Dr. Gunderson: The study found that: -   Gestational diabetes is a pregnancy complication that reveals a woman’s greater risk of future heart disease. -   Women who experience gestational diabetes face an increased risk of subclinical atherosclerosis (early heart disease) even if they do not develop type 2 diabetes or the metabolic syndrome years after pregnancy. -   Study participants with a history of gestational diabetes who did not develop diabetes or metabolic syndrome showed a greater carotid artery wall thickness (marker of early atherosclerosis) compared to those who never experienced gestational diabetes.  The vessel narrowing also could not be attributed to obesity or other risk factors for heart disease that were measured before pregnancy. -   Weight gain and blood pressure elevations in women with gestational diabetes were responsible for these differences in the artery wall thickness.

Lynda D. Lisabeth, PhD Interim Chair and Associate Professor Department of Epidemiology University of Michigan Ann Arbor, MichiganMedicalResearch.com Interview with: Lynda D. Lisabeth, PhD Interim Chair and Associate Professor Department of Epidemiology University of Michigan Ann Arbor, Michigan MedicalResearch.com: What are the main findings of the study? Dr. Lisabeth: The main findings were that Mexican Americans scored worse than non-Hispanic whites on all outcomes measured at 90 days following stroke, including neurologic, functional and cognitive outcomes, after adjustment for confounding factors. Further, we found that one-third of Mexican American stroke survivors have post-stroke dementia. Mexican Americans experienced more aphasia than non-Hispanic whites. Levels of functional impairment were substantial, with Mexican Americans on average experiencing moderate functional disability. Mexican Americans reported significantly greater difficulty than non-Hispanic whites with all activities of daily living (ADLs) and instrumental activities of daily living (IADLs) that were studied.

Atte Meretoja, MD, PhD, MSc (Stroke Medicine) Associate Professor and Principal Fellow (Neurology), University of Melbourne The Royal Melbourne Hospital L4C, Grattan St, Parkville VIC 3050, Australia Associate Professor of Neurology, University of Helsinki Helsinki University Central Hospital, FinlandMedicalResearch.com Interview with: Atte Meretoja, MD, PhD, MSc (Stroke Medicine) Associate Professor and Principal Fellow (Neurology), University of Melbourne The Royal Melbourne Hospital Australia Associate Professor of Neurology, University of Helsinki Helsinki University Central Hospital, Finland MedicalResearch.com: What are the main findings of the study? Dr. Meretoja: We used observational prospective data of consecutive stroke patients (n=2258) treated with intravenous thrombolysis in Australian and Finnish centers and a pooled analysis of thrombolysis trials to model the shift in patient outcomes with reducing treatment delays. We found out that each minute the treatment can be delivered faster granted on average 1.8 days of extra healthy life (95% prediction interval 0.9 to 2.7). In practice, this means that each 15 minute decrease in treatment delays provides an average equivalent of one month of additional disability-free life. (more…)

MedicalResearch.com Interview with: Maria Lorenza Muiesan Department of Clinical and Experimental Sciences University of Brescia, Internal Medicine Brescia, Italy. MedicalResearch.com: What are the main findings of the study? Dr. Muisean: An increase in the ratio of retinal arteries wall thickness to lumen diameter may serve as an in-vivo parameter of microvascular damage. We conducted a study that examined the relationship between changes in retinal arterioles wall thickness/ lumen diameter and several measures of blood pressure, including clinic brachial blood pressure,  24 hours brachial blood pressure and central aortic blood pressure. We found that the an increase of wall-to-lumen ratio of retinal arterioles was most closely related to 24 hours blood pressure. (more…)

Dr. James Sheppard MRC Research Fellow Department of Primary Care Health Sciences University of OxfordMedicalResearch.com Interview with Dr. James Sheppard MRC Research Fellow Department of Primary Care Health Sciences University of Oxford MedicalResearch.com: What are the main findings of the study? Dr. Sheppard: The aim of our study was to develop a decision-tree model which estimates the cost-effectiveness and potential implementation costs of a series of interventions which increase thrombolysis rates in acute stroke. The model examined all possible acute stroke patient pathways and was based on real life patient data. We found all proposed interventions to be cost saving whilst increasing patient quality of life after stroke. We estimate that, assuming a "willingness-to-pay"  of USD $30,000 per quality adjusted life year gained, the potential budget available to deliver interventions which improve acute stroke care range from USD $50,000 to USD $144,000.

MedicalResearch.com Interview with: Xiaohui Zhuo PhD Health economist Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention MedicalResearch.com: What are the main findings of the study? First, someone diagnosed with type 2 diabetes may pay an average of about $85,500 treating the disease over his or her lifetime. Lifetime cost is higher for women, and for patients who developed the disease earlier in life. Second, treating diabetic complications account for more than half of lifetime costs, and a majority of which is attributed by damage to large blood vessels, which can lead to coronary heart disease and stroke.
