MedicalResearch.com Interview with: Dr Andrea Schuessler QIMR Berghofer Medical Research Institute Herston, Queensland 4006 MedicalResearch.com: What are the main findings of the study? Dr . Schuessler: Recurrent glioblastoma is a very aggressive brain cancer and most patients do not survive much longer than 6 months. Our study has assessed a novel immunotherapy and treated 10 patients with late stage cancer. The treatment did not have any serious side effects and most of the patients have survived much longer than the expected 6 months. Importantly, four of the 10 patients have not shown signs of disease progression during the study period with one of them still being cancer free four years after the treatment. (more…)

Dr. Richard Body Emergency Department Manchester Royal Infirmary Manchester UKMedicalResearch.com Interview with:  Dr. Richard Body Emergency Department Manchester Royal Infirmary Manchester UK   MedicalResearch.com: What are the main findings of the study? Dr. Body: This paper actually reports the findings of two consecutive, separate studies.  We aimed to derive and then externally validate a clinical decision rule to risk stratify patients with suspected acute coronary syndromes in the Emergency Department (ED).  This rule could then be used to reduce unnecessary hospital admissions while also making judicious use of specialist high dependency resources. In the first study we derived a clinical decision rule that incorporates 8 variables: high sensitivity troponin T, heart-type fatty acid binding protein; ECG ischaemia; worsening angina; hypotension (systolic blood pressure <100mmHg on arrival); sweating observed in the ED; pain associated with vomiting; and pain radiating to the right arm or shoulder.  When we validated the rule at a different centre, we found that its use could have avoided hospital admission for over a quarter of patients while effectively risk stratifying others.  Of the 10% of patients who were identified as 'high risk', approximately 95% had a major adverse cardiac event within 30 days.  The findings suggest that the Manchester Acute Coronary Syndromes (MACS) decision rule could be used to 'rule in' and 'rule out' acute coronary syndromes immediately, using information gathered at the time of initial presentation to the ED.  Before clinical implementation, we recommend that effect of using the MACS rule in practice should first be evaluated in a trial setting.  This will enable us to determine: (a) whether physicians and patients are likely to comply with (and be satisfied with) the MACS rule; (b) the safety of the MACS rule when used in practice; and (c) whether use of the MACS rule leads to cost savings for the health service.

dr_arturo_araujoMedicalResearch.com Interview with: Arturo Araujo, PhD IMO Moffitt Cancer Center Tampa, FL 33612   MedicalResearch: What are the main findings of the study? Dr. Araujo: Using in vivo approaches it is often challenging to study the multiple simultaneous interactions occurring at various time points in the setting of bone metastasis. However, integrating biological data with a powerful computational model allowed us to build a tool that could not only mimic the in vivo growth of cancer in bone but also to determine how the disease was behaving at any given time point. The key finding for us was that the computational model demonstrated the phasic or cyclical nature of how the prostate cancers grow in bone. For example, a wave of osteoclast mediated bone resorption would be followed by sustained bone formation by osteoblasts, followed again by bone reposition. We think these findings could provide novel insights into when the best time to apply therapies might be in order to obtain maximum efficiency. (more…)

Marianna Virtanen Finnish Institute of Occupational Health Helsinki, FinlandMedicalResearch.com Interview with: Marianna Virtanen PhD Finnish Institute of Occupational Health Helsinki, Finland MedicalResearch: What are the main findings of the study? Dr. Virtanen: We examined whether psychological distress predicts incident type 2 diabetes and if the association differs between populations at higher or lower risk of type 2 diabetes. We used a clinical type 2 diabetes risk score to assess future diabetes risk and in addition, participants’ prediabetes status. We found that psychological distress did not predict future type 2 diabetes among participants who were normoglycemic and among those with prediabetes combined with a low diabetes risk score. However, psychological distress doubled the risk of type 2 diabetes among participants with prediabetes and a high diabetes risk score. (more…)

Michael H. Hall, MD North Shore-LIJ Health SystemMedicalResearch.com Interview with: Michael H. Hall, MD North Shore-LIJ Health System MedicalResearch: What are the key points of your research? Dr. Hall: Our study was designed to improve care transition from the hospital to home after coronary bypass surgery. The innovative program (Follow Your Heart), implemented at one of our system hospitals, involves sending cardiac surgery nurse practitioners (NPs) who cared for the patients in the hospital to the homes of discharged patients for at least two visits in the first two weeks after discharge. Their goal is to provide continuity of care for patients that they know from the hospital setting and to provide robust medication management, coordinate community services, and be a communications hub for hospital and community providers (primary care, cardiology, and community nurse home visit services). The  nurse practitioners interact with community resources to ensure understanding and satisfaction of the patients’ needs prior to hand-off to those resources after two weeks. Our  nurse practitioners utilize encrypted smart phones to provide reports to all appropriate providers and can even send pictures of incisions to the surgeon when necessary. (more…)

Tina Hieken, M.D. Associate Professor of Surgery Mayo Clinic,Rochester, MinnMedicalResearch.com Interview with: Tina Hieken, M.D. Associate Professor of Surgery Mayo Clinic,Rochester, Minn   MedicalResearch.com: What are the main findings of the study? Dr. Hieken: Among more than 1,300 newly diagnosed invasive breast cancer patients, 36 percent of whom were obese (BMI ≥ 30), preoperative axillary ultrasound with fine needle aspiration biopsy of suspicious lymph nodes identified metastasis to the lymph nodes in 36 percent of patients found to be node-positive at operation.  For all BMI categories (normal, overweight, obese) axillary ultrasound was predictive of pathologic nodal status (p<0.0001).  The sensitivity of axillary ultrasound did not differ across BMI categories while specificity and accuracy were better for overweight and obese patients, respectively, than for normal weight patients.  Furthermore, patients across all BMI categories who had suspicious axillary lymph nodes on ultrasound and had a positive fine needle aspiration biopsy had significantly more positive lymph nodes at operation, an average of five metastatic nodes, and an overall higher nodal disease burden at operation.

dr_elizabeth_devoreMedicalResearch.com Interview with: Elizabeth Devore, ScD Associate Epidemiologist Brigham and Women’s Hospital Instructor in Medicine, Harvard Medical School   MedicalResearch.com: What are the main findings of the study? Dr. Devore: In this study, we examined sleep duration and memory performance in a group of ~15,000 women participating in the Nurses’ Health Study. We found that women with sleep durations of 5 or fewer hours/day or 9 or more hours/day, either in midlife or later life, had worse memory at older ages than those sleeping 7 hours/day. In addition, women with sleep durations that changed by two or more hours/day from midlife to later life performed worse on memory tests compared to those whose sleep duration did not change during that time period.The magnitude of these memory differences was approximately equivalent to being 1-2 years older in age.

Answer: This is the first study to show that greater intake of dietary fiber, especially cereal fiber, was inversely associated with all-cause mortality. Participants increased their average dietary fiber intake after myocardial infarction (MI), and the greater the increase, the lower was the risk of subsequent all-cause and cardiovascular mortality. Overall, the benefits for increased fiber intake were strongest for fiber from cereal and grain sources. (more…)

 Dr. Wang: 
This meta-analysis has systematically reviewed 25 relevant studies composed of 17,332 cancer cases to give a comprehensive perspective on the relationship between vitamin D and cancer patient outcomes. Our result demonstrated that vitamin D levels are linked to better outcomes in several types of cancer patients. The strongest link was found in breast cancer, lymphoma and colorectal cancer. There was less evidence of a connection in people with lung cancer, gastric cancer, prostate cancer, leukemia, melanoma or Merkel cell carcinoma, but the available data were positive. We also found that a 10 nmol/L increase in vitamin D levels was tied to a 4 percent increase in survival among people with cancer. (more…)

Dr. Lewis: We tested the hypothesis raised by others that calcium supplementation with or without vitamin D increases coronary heart disease and mortality risk in elderly women. To do this we undertook a meta-analysis of published and unpublished data from patient level and cluster randomized controlled trials of calcium supplements with or without vitamin D in elderly women. Importantly all events included in this large meta-analysis were verified by clinical review, hospital record or death certificate. We did not observe any significant increase in all-cause mortality or coronary heart disease events that included myocardial infarction, angina pectoris and acute coronary syndromes and chronic coronary heart disease.

Dr. McKenzie: Our study was the first to compare and describe epidemiological patterns of basketball-related injuries presenting for treatment to emergency departments and to the high school athletic training setting using surveillance data captured from large, nationally representative samples. Specifically, we compared estimated national incidence, rates of injury and body sites injured, and diagnoses. Nationally, an estimated 1,514,957 athletes with basketball-related injuries reported to the emergency department and 1,064,551 presented to the athletic training setting. Patterns of basketball-related injuries presenting to the emergency department differ from those presenting to the high school athletic training setting for treatment, with those presenting to the emergency department being more severe. In general, injuries that could be relatively quickly assessed and more easily diagnosed and treated, such as strains and/or sprains, presented more commonly to the athletic training setting, while injuries that required more extensive diagnostic or treatment procedures, such as fractures, were treated more commonly in the emergency department.

Professor Stuart Allan Faculty of Life Sciences, AV Hill Building The University of Manchester Manchester, M13 9PTMedicalResearch.com Interview with: Professor Stuart Allan Faculty of Life Sciences, AV Hill Building The University of Manchester Manchester, M13 9PT MedicalResearch.com: What are the main findings of the study? Dr. Allan: Using an experimental model of stroke it was found that animals with preceding Streptococcus pneumoniae infection had a worse outcome than uninfected animals. This confirms and extends previous data, both clinical and preclinical, that systemic inflammation is a key contributor to stroke outcome. Importantly, effects of infection were also demonstrated in animals with co-morbidities associated with stroke (atherosclerosis and age), with outcomes worse than observed in healthy young subjects. Exacerbating effects of infection on stroke are mediated via the pro-inflammatory cytokine, interleukin-1 (IL-1), shown by reversal of the increased ischaemic brain damage and functional impairments by treatment with the IL-1 receptor antagonist (IL-1Ra). Infection also leads to increased platelet activation and microvascular coagulation after stroke, which contributes to the increased injury. Collectively, these data are the first to show, how systemic inflammatory mechanisms induced by one of the most common non-invasive, human S.pneumoniae isolates, lead to critical illness after stroke in different rodent species and strains, and how common stroke comorbidities interact with infection to worsen outcome after stroke.

Prof. O'Brien: Using a randomised trial format we compared the diabetes status at two years after a program of multidisciplinary diabetes care (MDC) alone or with the addition of a Lap-Band procedure in 50 people who were overweight (BMI 25-30) and with diabetes. 52% of the Lap-Band group had remission of their diabetes as measured by glucose tolerance testing compared to 8% in the multidisciplinary diabetes care group. The Lap-Band procedures were performed as outpatients with a 2-3 hr length of stay. There were no perioperative adverse events. The surgical group had lost a mean of 11.5kg in weight. The incremental cost effectiveness ratio (ICER) for remission of diabetes was AUD $20,700. (more…)

MedicalResearch.com: Egle Avizienyte, PhD Senior Research Fellow, Institute of Cancer Sciences Faculty of Medical and Human Sciences The University of Manchester, Manchester M20 4BX MedicalResearch.com: What are the main findings of the study? Dr. Avizienyte: Angiogenesis, the formation of new blood vessels, has been validated as a target in ovarian cancer. However, the benefit from anti-angiogenic therapies, e.g. Vascular Endothelial Growth Factor (VEGF) pathway inhibitors that are currently used in the clinic for the treatment of ovarian cancer has been modest, largely because of redundancy in angiogenic cytokines that regulate tumour angiogenesis. In this study we validated heparan sulphate 6-O-sulfotranferases 1 and 2 (HS6ST-1 and -2) as targets for developing new therapeutic anti-angiogenic agents for the treatment of ovarian cancer. The data generated in our laboratory show that HS6STs induce the angiogenic programme in ovarian cancer cells and has a major effect on tumour angiogenesis. (more…)

Dr. Bowrey: Of 103 patients who had undergone Roux en Y gastric bypass surgery, changes in appetite, taste and smell were noted in 97%, 73% and 42% respectively. Seventy-three percent of patients developed aversions to certain types of foods, most frequently meat, starch and dairy produce. The change in taste sensation for the three common modalities of "sweet", "salt" and "sour" was decreased in some patients and increased in other patients. Patients who experienced food aversions typically experienced more weight loss than patients not developing aversions. (more…)

Mr. Thamara Perera FRCS Consultant Surgeon - Multi Organ Retrieval and Liver Transplant Liver Transplant - University Hospitals Birmingham NHS Foundation Trust Queen Elizabeth Hospital, Queen Elizabeth Medical Centre, Birmingham, UKMedicalResearch.com Interview with: Mr. Thamara Perera FRCS Consultant Surgeon - Multi Organ Retrieval and Liver Transplant Liver Transplant - University Hospitals Birmingham NHS Foundation Trust, Queen Elizabeth Hospital, Queen Elizabeth Medical Centre, Birmingham, UK MedicalResearch.com: What are the main findings of the study? Answer: In this study we compared the basic energy metabolism of liver grafts obtained from conventional and widely practiced form of organ donation, the donation after brain death (DBD) donors, and recently revived form of organ donation called donation after circulatory death (DCD) donors. To introduce a background to this study - DCD liver grafts are perceived as marginal liver grafts, owing to the basic differences surrounding the organ donation. DCD organs suffer a period of warm ischemia from the time of treatment withdrawal in a potential donor up until the organs are actually recovered and preservation is initiated. Although the DCD liver grafts have supplemented the donor organ pool, the initial and short-term results following liver transplantation are comparatively poor and these differences are attributable to the donor warm ischemia. However there were no studies in the literature examining the energy status of DCD liver grafts and our study is the first such study. (more…)

Dr. Bombard: The main finding of the study is that gene expression profiling tests play a critical role when women with early-stage breast cancer decide whether to have chemotherapy, but many of them do not fully understand what some of the test results mean. For many the gene expression profiling test was the main factor in their treatment decision. The women we interviewed understood the test would indicate whether chemotherapy would be beneficial to them. But many thought the test reflected their unique circumstances and did not understand that their test result was based on larger population statistics. Patients often viewed their gene expression profiling results as providing information that was more scientifically valid, uniquely personalized and emotionally significant than any other information they had received. For many, the test was a transformational element that empowered them, allowed them to feel confident in their decisions and may even have rescued them from unnecessary chemotherapy. Patients described emotionally and socially complex reasons why they valued gene expression profiling testing in making their treatment decisions. Patients valued the test because it provided them with certainty amidst confusion, with options and a sense of empowerment, and with personalized, authoritative information. (more…)

Dr. Sugiyama: In the US nationally representative sample from the National Health and Nutrition Examination Survey 1999-2010, we found that statin users in 2009-2010 eat 9.6% more calories and 14.4% more fat than statin users in 1999-2000. These increases were not observed in statin non-users; the trends of caloric and fat intake were statistically different between statin users and non-users. In 1999-2000, caloric and fat intake was significantly less for statin users compared with non-users, but the difference between the groups because smaller as time went by and there was no statistical difference in 2009-2010. Body mass index increased more rapidly for statin users compared to non-users. (more…)

Tara Lagu MD PhD Assistant Professor of Medicine Tufts University School of MedicineMedicalResearch.com Interview with: Tara Lagu MD PhD Assistant Professor of Medicine Tufts University School of Medicine   MedicalResearch.com: What are the main findings of the study? Dr. Lagu: We found that use of mechanical ventilation in patients 65 and older is increasing rapidly. If current rates of increase continue, we expect that by 2020 there will be more than 600,000 hospitalizations per year that involve mechanical ventilation. This is a doubling in 20 years (2001-2020), and represents demand that could easily exceed the capacity of the US critical care system. We also found that increase in use among patients with dementia is 4 times faster than those without dementia. This is important because dementia is a terminal illness, and use of mechanical ventilation in patients with end-stage dementia is associated with poor 30-day and 1-year outcomes. (more…)

MedicalResearch.com: What are the main findings of the study? Dr. Chan: In this 1-year randomized study, we asked the question whether type 2 diabetic patients receiving team-based integrated care augmented by information technology would further improve in their glycemic control if given additional peer support through the telephone. All patients underwent comprehensive risk assessment guided by the web-based JADE portal which generated personalized risk report with attained treatment targets and decision support. After 1 year, all patients improved significantly in all risk factors including A1c with improved treatment adherence, self efficacy and psychological wellbeing. Although the peer support group did not further improve in A1c, short-stay hospitalization rates were substantially reduced by 50% , especially amongst those with emotional distress. These patients accounted for 20% of the intervention group, in whom peer support further reduced psychological distress and treatment non-adherence. (more…)

MedicalResearch.com Interview Invitation Karin J. H. Verweij, PhD Department of Developmental Psychology and EMGO Institute for Health and Care Research,  VU University Amsterdam, the Netherlands MedicalResearch.com: What are the main findings of the study? Dr. Verweij: We performed a twin study using over 10,000 adult Australian twins to determine the relative importance of genetic and environmental influences on individual differences in non-suicidal self-injury (NSSI) and suicidal ideation and their covariation. We found that individuals that report self-harm are approximately eight times more likely to also report suicidal ideation. Results from the bivariate genetic model indicated that the substantial correlation between non-suicidal self-injury and suicidal ideation (r=0.49 for males and 0.61 for females) is largely explained by overlapping genetic factors: 62% and 76% for males and females, respectively. Overlapping residual influences, including nonshared environmental influences and measurement error, also explain part of the covariance between the two traits. These findings suggest that the two behaviors share similar biological underpinnings. (more…)
