Dr. Pim A. de Jong, Department of Radiology University Medical Center Utrecht, Heidelberglaan 100, E.01.132, 3508GA Utrecht, the Netherlands. MedicalResearch.com: What are the main findings of the study? Dr. de Jong: The main findings of the study is that lung cancer screening CT scans can predict future cardiovascular events. MedicalResearch.com: Where any of the findings unexpected? Dr. de Jong: The unexpected aspect is that the CT scans were not-ECG gated, but even these non-gated scans were good enough to quantify arterial calcifications and predict risk.

Keith Summa MD/PhD Student Northwestern University Feinberg School of Medicine Chicago, Illinois, United States of AmericaMedicalResearch.com Interview with: Keith Summa MD/PhD Student Northwestern University Feinberg School of Medicine Chicago, Illinois, United States of America   Disruption of the Circadian Clock in Mice Increases Intestinal Permeability and Promotes Alcohol-Induced Pathology and Inflammation MedicalResearch.com: What are the main findings of the study? Answer: The main findings of the study were that disruption of circadian rhythms, which we achieved using independent genetic and environmental strategies in mice, leads to impaired function of the intestinal epithelial barrier. This loss of epithelial barrier integrity, which has been associated with numerous diseases, results in "gut leakiness," a phenomenon in which endotoxin from gut bacteria can cross the intestinal wall and enter circulation, promoting inflammation. In particular, using in a disease model of gut-derived endotoxemia and inflammation, alcoholic liver disease, we found the circadian disruption interacted with alcohol, leading to increased gut leakiness, inflammation and liver damage.

MedicalResearch.com Interview with Batool Haider, MD, MS, DSc candidate Departments of Epidemiology and Nutrition School of Public Health Harvard University Anaemia, prenatal iron use, and risk of adverse pregnancy outcomes: systematic review and meta-analysis MedicalResearch.com: What are the main findings of the study? Dr. Haider: The main findings of the study are that iron use in the prenatal period increased maternal mean haemoglobin concentration by 4.59 (95% confidence interval 3.72 to 5.46) g/L compared with controls and significantly reduced the risk of anaemia (relative risk 0.50, 0.42 to 0.59), iron deficiency (0.59, 0.46 to 0.79), iron deficiency anaemia (0.40, 0.26 to 0.60), and low birth weight (0.81, 0.71 to 0.93). The effect of iron on preterm birth was not significant (relative risk 0.84, 0.68 to 1.03). Analysis of cohort studies showed a significantly higher risk of low birth weight (adjusted odds ratio 1.29, 1.09 to 1.53) and preterm birth (1.21, 1.13 to 1.30) with anaemia in the first or second trimester. Exposure-response analysis indicated that for every 10 mg increase in iron dose/day, up to 66 mg/day, the relative risk of maternal anaemia was 0.88 (0.84 to 0.92) (P for linear trend<0.001). Birth weight increased by 15.1 (6.0 to 24.2) g (P for linear trend=0.005) and risk of low birth weight decreased by 3% (relative risk 0.97, 0.95 to 0.98) for every 10 mg increase in dose/day (P for linear trend<0.001). Duration of use was not significantly associated with the outcomes after adjustment for dose. Furthermore, for each 1 g/L increase in mean haemoglobin, birth weight increased by 14.0 (6.8 to 21.8) g (P for linear trend=0.002); however, mean haemoglobin was not associated with the risk of low birth weight and preterm birth. No evidence of a significant effect on duration of gestation, small for gestational age births, and birth length was noted.

MedicalResearch.com:  What are the main findings of the study?

Answer:   Our longitudinal study showed that growing aneurysms have a significantly higher risk of rupture than aneurysms that are stable in size over time. Due to this increased risk, we recommend that all aneurysms, regardless of size, should be followed regularly to look for growth. We have also found that larger aneurysm size, aneurysm growth and cigarette smoking may independently increase the risk of rupture.

MedicalResearch.com Interview with: Dr Patrick Freund Spinal Cord Injury Center Balgrist University Hospital Zurich, University of Zurich Forchstrasse 380 8008 Zurich, SwitzerlandDr Patrick Freund Spinal Cord Injury Center Balgrist University Hospital Zurich, University of Zurich Forchstrasse 380 8008 Zurich, Switzerland MedicalResearch.com: What are the main findings of the study? Dr. Freund: Novel interventions targeting acute spinal cord injury (SCI) have entered clinical trials, but neuroimaging biomarkers reflecting structural changes within the central nervous system are still awaited. In chronic SCI, neuroimaging provided evidence of structural changes at spinal cord and brain level that could be related to disability. However, the pattern and time course of these structural changes and their potential to predict clinical outcomes is uncertain. In a prospective longitudinal study, thirteen patients with acute traumatic SCI were assessed clinically and by longitudinal MRI (within five weeks of injury, after two, six and twelve months) and were compared to eighteen healthy controls. Cross-sectional cord area, cranial white matter (CST) and grey matter (cortex) volume decrease was evident at baseline and progressed over twelve months. Multi-parametric mapping of myelin sensitive magnetization transfer (MT) and longitudinal relaxation rate (R1) was reduced both within and beyond the areas of atrophic changes. Better neurological and functional outcomes were associated with less atrophic changes of the CST in both cord and brain.

 MedicalResearch.com Interview with Salim S. Virani, MD, PhD Health Policy and Quality Program, Michael E. DeBakey Veterans Affairs Medical Center Health Services Research and Development Center of Excellence, and Section of Health Services Research, Department of Medicine, Baylor College of Medicine, Section of Cardiovascular Research, Department of Medicine, Baylor College of Medicine, and Center for Cardiovascular Disease Prevention, Methodist DeBakey Heart and Vascular Center, Houston, Texas MedicalResearch.com: What are the main findings of the study? Dr. Virani: The main findings of the study are that despite having cholesterol levels at goal (LDL cholesterol <100 mg/dL), about one-third of patients (9200 out of 27947) with coronary heart disease had repeat cholesterol testing in 11 months from their last lipid panel. As expected, no intervention was performed as a response to these lipid panels. Collectively, 12686 additional lipid panels were performed in these patients.  Among 13,114 patients who met the optional treatment target of LDL-C<70 mg/dL, repeat lipid testing was performed in 8,177 (62.3% of those with LDL-C<70) during 11 months of follow-up. Patients with a history of diabetes mellitus (odds ratio [OR], 1.16; 95% CI, 1.10-1.22), a history of hypertension (OR, 1.21; 95%CI, 1.13-1.30), higher illness burden (OR, 1.39; 95%CI, 1.23-1.57), and more frequent primary care visits (OR, 1.32; 95%CI, 1.25-1.39) were more likely to undergo repeat testing, whereas patients receiving care at a teaching facility (OR, 0.74; 95%CI, 0.69-0.80) or from a physician provider (OR, 0.93; 95%CI, 0.88-0.98) and those with a medication possession ratio of 0.8 or higher (OR, 0.75; 95%CI, 0.71-0.80) were less likely to undergo repeat testing.

Melanoma Survival Disadvantage in Young, Non-Hispanic White Males Compared With Females

MedicalResearch.com: What are the main findings of the study? Dr. Swetter: Women diagnosed with melanoma tend to fare better than men in terms of improved survival, and this has mostly been attributed to better screening practices and behaviors in women that result in thinner, more curable tumors, and/or more frequent physician visits in older individuals that result in earlier detection.  Our study focused on survival differences between young men and women (ages 15-39 years) diagnosed with cutaneous (skin) melanoma, who constitute a generally healthy population compared to the older adults that have usually been studied. We found that young men were 55% more likely to die of melanoma than age-matched women, despite adjustment for factors that may affect prognosis, such as tumor thickness, histology and location of the melanoma, as well as presence and extent of metastasis. Our results present further evidence that a biologic mechanism may contribute to the sex disparity in melanoma survival, since adolescent and young adults see physicians less frequently and are less likely to have sex-related behavior differences in skin cancer screening practices than older individuals.

MedicalResearch.com Interview with: Sam R. Telford III, ScD Department of Infectious Disease and Global Health, Tufts University, Cummings School of Veterinary Medicine, 200 Westboro Road, North Grafton, MA Borrelia miyamotoi Infection Presenting as Human Granulocytic Anaplasmosis: A Case Report MedicalResearch.com: What are the main findings of the study? Answer: The study presents two additional cases of BMD (Borrelia miyamotoi disease) that add to our knowledge of the spectrum of illness of this recently recognized zoonosis.  Our report of the North American index case in NEJM in January 2013 described a case-patient who was elderly and immunocompromised and it was not clear whether that case was just very unusual.  With our Annals report, we describe cases in immune-intact individuals and suggest that cases of BMD may have been under our noses all along, just presumptively diagnosed as HGA and successfully treated with doxycycline with no followup (e.g., lab confirmation of diagnosis of HGA Human Granulocytic Anaplasmosis).  Hence, individuals presenting with fever, headache, myalgia, and show leukopenia and elevated LFTs may have either HGA or BMD and confirmatory testing should be done accordingly.  It should be noted that all tick borne diseases are clinical diagnoses and treatment of an acute case should not depend on "lab tests".  Both these infections are effectively managed by oral doxycycline, hence those with these signs and symptoms might be empirically treated with doxycyline, which would be important in areas where RMSF and tularemia (which also produce leukopenia and elevated LFTs) co-occur with deer tick -transmitted infections such as Lyme disease; waiting for "lab tests" to confirm RMSF or tularemia might lead to a negative outcome.  RMSF and tularemia are the most dangerous of the tick American tick borne diseases, although I would certainly place the very rare deer tick virus and Powassan virus in the same category.

Interview with: Miguel Ramalho-Santos, Ph.D. University of California - San Francisco stem-cell scientist,MedicalResearch.com  Interview with: Miguel Ramalho-Santos, Ph.D. University of California - San Francisco stem-cell scientist, Vitamin C induces Tet-dependent DNA demethylation and a blastocyst-like state in ES cells MedicalResearch.com: What are the main findings of the study? Answer: We found that Vitamin C has a profound effect in the regulation of gene activity in cultured mouse embryonic stem cells. Vitamin C specifically enhances the action of enzymes called Tet's, which remove certain chemical modifications to DNA (methylation). In this way, Vitamin C makes cultured mouse embryonic stem cells behave more like the early cells in the embryo that they represent.

MedicalResearch.com Interview with: Sarah H. O'Connell M.D. PGY-4 Yale New Haven Hospital Yale School of Medicine Department of Diagnostic Radiology MedicalResearch.com:  What are the main findings of the study? Answer: The purpose of our study was to evaluate the visibility of cancers in women at high-risk for breast cancer on 2D mammography compared to digital breast tomosynthesis. In other words, how would the use of tomosynthesis contribute to cancer visualization in this population  of patients? We evaluated the cancers seen in both high-risk patients, those with a >20% lifetime risk of breast cancer, and intermediate risk  patients, those with a 15-20% lifetime risk of breast cancer, for a total of 56 cancers. We found that 41% (23/56) cancers were better seen on tomosynthesis and 4% (2/56) were only seen on tomosynthesis. The majority of the cancers seen better or only on tomosynthesis  presented as masses rather than as calcifications alone which were better seen on 2D mammography.

Dr. Li: The main finding is that intake marine n-3 polyunsaturated fatty acids (n-3 PUFAs) from both fish and fish oil lower the risk of breast cancer. Women with a high intake of marine n-3 PUFAs had a 14-percent reduction in risk of breast cancer compared with those who had a low intake. Every 0.1 g increase in marine n-3 PUFA per day was linked to a five-percent reduction in breast cancer risk.

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.

Joynt, MD MPH Cardiovascular Division Brigham and Women's Hospital and VA Boston Healthcare System Department of Health Policy and Management, Harvard School of Public Health MedicalResearch.com: What are the main findings of the study? Dr. Joynt:  The main findings of the study were two-fold. First, high-cost patients in Medicare (the top decile of spenders) are responsible for about 80% of inpatient spending in the Medicare program, so understanding more about these patients' patterns of care is really important. Second, we found that only about 10% of acute-care spending for these high-cost Medicare patients were for causes that we generally think of as preventable in the short term, like uncontrolled diabetes, COPD, or heart failure. The rest of the spending was for acute conditions that we generally don't think of as preventable (at least in the short term), such as orthopedic procedures, sepsis, and cancer.

Dr. Kumar Dharmarajan MD MBA Yale School of Medicine Center for Outcomes Research & Evaluation (CORE)Contraindicated Initiation of β-Blocker Therapy in Patients Hospitalized for Heart FailureMedicalResearch.com  Interview with Dr. Kumar Dharmarajan MD MBA

Yale School of Medicine Center for Outcomes Research & Evaluation (CORE)Contraindicated Initiation of β-Blocker Therapy in Patients Hospitalized for Heart Failure MedicalResearch.com: What are the main findings of the study? We found that among a large contemporary cohort of heart failure hospitalizations, beta blockers are frequently started in patients with markers of clinical instability such as residence in an intensive care unit (ICU), volume overload requiring intravenous diuresis, and poor cardiac output requiring intravenous inotropes. Approximately 40% of patients in whom a beta blocker is started has at least one of these three potential contraindications to treatment. This finding is concerning, as recent performance measures for heart failure recommend that a beta blocker be started during hospitalization for heart failure among patients with left ventricular systolic dysfunction. However, these performance measures also state that persons in whom a beta blocker is started "should not be hospitalized in an ICU, should have no or minimal evidence of fluid overload or volume depletion, and should not have required recent treatment with an intravenous positive inotropic agent." Moving forward, we are concerned that the unselective application of the new performance measure may lead to the further use of beta blocker therapy in patients at higher risk for adverse consequences of therapy.

MedicalResearch.com Interview with: Saeid Shahidi, MD. Chief Consultant in supra-aortic surgery. Vascular Unit, Regional Hospital Slagelse, Region Zealand, Denmark. MedicalResearch.com: What is the background of your study? Answer: Our Prospective Population-based study showed, an expedited CEA can be performed in the subacute period ( >2 - <30 days) without significantly increasing the operative risk. The acute admission and urgent aggressive BMT with dual therapy in our cohort was associated with significant reduction P<0.00001 in the risk of early neurological recurrent (NR) in the CEA patient. It seems that in neurologically stable patients CEA can wait up to 30 days provided urgent BMT has been started in specialized stroke/ TIA clinics. Our study also adds to the data on the benefit of specialist TIA clinics.

MedicalResearch.com eInterview with: Michael Bang Petersen Associate Professor, PhD Department of Political Science Aarhus University, Denmark MedicalResearch.com: What are the main findings of the study? Answer: While many think of politics as a modern phenomenon, politics has – in a sense – been with our species always. Our ancestors have been group living animals for millions of years and it would be surprising if natural selection had not shaped our ancestors’ psychology to navigate core political situations including how to manage resource conflicts. In this article, we applied this insight to the study of attitudes towards economic redistribution and theorized about the kinds of factors that an evolved psychology of conflict navigation would consider important. Given that we evolved in small-scale groups and many conflicts would have to be settled face-to-face, one such factor – at least, for males – would be physical strength. Essentially, stronger males should be more likely to escalate conflicts and pursuit their self-interest. On modern political issues of economic redistribution, self-interest is determined by socio-economic status (SES). Individuals with high SES have an interest in decreasing redistribution, whereas individuals with low SES have an interest in increasing redistribution. On this basis, an adaptationist perspective on the psychology of redistribution attitudes predicts that for rich males upper-body strength should decrease support for redistribution. For poor males, in contrast, upper-body strength should increase support for redistribution. This is what we found in three highly different countries: the United States, Denmark and Argentina. Cross countries, physically strong males opted for the self-interested political position.
