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, VitaminC 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. (more…)

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. (more…)

Genevieve Kenney Ph.D Senior Fellow and Co-Director, Health Policy Center The Urban Institute 2100 M Street NW Washington DC 20037MedicalResearch.com  Interview with Genevieve Kenney Ph.D Senior Fellow and Co-Director, Health Policy Center The Urban Institute 2100 M Street NW Washington DC 20037 MedicalResearch.com: What are the main findings of the study? Dr. Kenney: Our study is the first published analysis that draws on physical examinations, laboratory tests, and patient reports to assess the health needs and health risks of uninsured adults who could be eligible for Medicaid coverage under the Affordable Care Act relative to the adults who are already enrolled in Medicaid. Our main findings are that the uninsured adults who could enroll under the ACA are less likely than the adults with Medicaid coverage to be obese and to have functional limitations and chronic health problems, such as hypertension, hypercholesterolemia, or diabetes, but that the uninsured adults with these chronic conditions are less likely to be aware that they have them and less likely to have the condition under control. In comparison to the Medicaid population, the uninsured adults in our study were also less likely to have seen a health professional in the prior year and to have a routine place for care.  The rates of undiagnosed and uncontrolled chronic health care problems found in our study indicate that millions of low-income uninsured adults are currently at risk of premature mortality and other significant health issues.  These findings provide new evidence of the potential health benefits associated with the Medicaid expansion under the Affordable Care Act.

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. (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.

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. (more…)

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. (more…)

MedicalResearch.com Interview with Dr. H. Irene Hall, PhD Division of HIV/AIDS Prevention National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, CDC 1600 Clifton Road, MS E-47, Atlanta, GA 30333 MedicalResearch.com: What are the main findings of the study? Dr. Hall: Our research finds that, across all populations, far too few Americans with HIV receive the care they need to stay healthy and reduce risk of transmission. According to our research, gaps in care are the largest among African Americans and young people. Moving forward, improving care for all HIV-infected people will be critical to achieving the goal of an AIDS-free generation in America. More specifically, some of the key findings of the study include:
  • Overall, only a quarter of all Americans with HIV have a suppressed viral load – meaning the level of HIV in their bodies is low enough to stay healthy and dramatically reduce the chance of transmitting to others.
  • By race/ethnicity, African-Americans and Hispanics or Latinos are less likely to be aware of their infection compared to whites.
  •  By age, younger Americans are less likely to be in ongoing care and have a suppressed viral load; HIV care and viral suppression generally improved with age. For example:
  • Fifteen percent of those aged 25-34 were virally suppressed, compared to 36 percent of those aged 55-64.
  • In terms of ongoing care, 28 percent of those 25-34 years old were retained in care, compared to 46 percent of those aged 55-64. (more…)

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…)

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. (more…)

DR. RAUL ZAMORA-ROS, PhD. POSDOCTORAL FELLOW UNIT OF NUTRITION, ENVIRONMENT AND CANCER CATALAN INSTITUTE OF ONCOLOGY (ICO) – BELLVITGE BIOMEDICAL RESEARCH INSTITUTE (IDIBELL) BARCELONA, SPAIN MedicalResearch.com: What are the main findings of the study? Dr. Zamora-Ros:  Our study shows that diets rich on flavonoids (polyphenols ubiquitously distributed in the plant kingdom, such as in fruit, vegetables, tea, wine and chocolate), particularly flavonols, are associated with less esophageal cancer risk, especially in current smokers. Tobacco smoking causes oxidative stress, and both oxidative stress and smoking tobacco are related to increased esophageal cancer risk. Therefore, our data suggest that the possible protective mechanism of dietary flavonoids may be related to their antioxidant properties, which may not be attributed to the direct antioxidant action, but to the ability to modulate antioxidant enzymatic pathways.

TITLE: Retinal Vessel Caliber and Lifelong Neuropsychological Functioning An international research team from the USA, UK, Singapore and New Zealand reports that the size of the blood vessels in the back of the eye can indicate the health of the brain of people approaching midlife (age 38 years), years before age-related declines in brain functioning. PUBLICATION SOURCE: Psychological Science, advance online publication date, May 2013.   BACKGROUND:
  • Young people who score low on IQ tests, tend to be at higher risk for diseases in later life, and even tend to die younger.
  • One plausible explanation for this link is that intelligence tests assess brain health.
  • Digital retinal imaging is a relatively new and non-invasive method to visualize the small blood vessels in the retina, at the back of the eye. The small vessels in the eye may reflect the conditions of the vessels inside the brain because both eye and brain vessels share similar size, structure and function. Thus, retinal imaging can provide a window to study the health of the brain in living humans.
  • We studied the link between retinal vessel width and intelligence tests scores in the representative Dunedin birth cohort of 1000 New Zealanders born in 1972-73, and followed for 38 years with repeated assessments.
  • Using a digital fundus camera, which can photograph the interior surface of the eye, we were able to assess the size of the small blood-vessels in the retina, namely, the arterioles and venules (the small branches of the arteries and veins). We also administered intelligence tests in childhood and adulthood.
THE FINDING:
  • We found that study members who presented with wider venules had poorer intelligence tests scores at midlife (age 38 years). This finding held up independently of potential factors that may explain this link, such as low socio-economic status, smoking, or diabetes.
  • Moreover, wider venules in the eye were linked with lower childhood IQ that had been tested 25 years earlier.

MedicalResearch.com Interview with: Frederick M. Brown, Ph.D. Associate Professor The Pennsylvania State University Department of Psychology, Cognitive and Wellness Director, Human Performance Rhythms Laboratory MedicalResearch.com:  What was the primary finding of your study? Dr. Brown: Time of day of an occupation, as well as a regular versus irregular routine, may influence whether a person wants to go into it or not. Most educational research has focused on academic major selection motivated by job aptitude, personality, and sociocultural factors. Our findings suggest that a person’s genetically determined built-in morning versus evening (M/E) preference for best time of day to work or sleep may influence career choice in two important ways: This M/E preference for work and sleep is related to 1) personality and to 2) the time of day the job is executed. These may interact with how much sleep a person thinks they need. In addition to the personality traits associated with M/E, such as morning people being more introverted and evening people more extroverted, an individual’s choice of major may be influenced by their preference for the typical work hours of a profession, such as a routine 9-to-5 schedule versus irregular evening and weekend work.

MedicalResearch.com eInterview with: Dr. Reena Pattani MD Department of Medicine St. Michael’s Hospital 30 Bond Street, Toronto ON M5B 1W8 MedicalResearch.com: What are the main findings of the study? Dr. Pattani: We performed a meta-analysis of 16 studies that assessed the effectiveness of probiotics administered concurrently with antibiotics compared to the use of antibiotics alone. The use of probiotics among patients in these trials reduced the risk of antibiotic-associated diarrhea by almost 40% and decreased the rate of Clostridium difficile infection by 63%. On subgroup analysis, the reduction remained statistically significant for the subgroups of good quality trials, trials in which a primarily Lactobacillus-based regimen was used, and those studies which had a follow-up period of less than 4 weeks.

Answer: We find that one of the welfare time limit experiments that led to welfare reform in the United States in 1996 led to increases in mortality rates among experimental group participants over 14-15 years of follow up. MedicalResearch.com: Were any of the findings unexpected? Answer: Yes. Welfare reform led to increases in employment among the experimental group participants. Employment has long been hypothesized to reduce mortality. We examined this experiment to explore whether increases in employment among those exposed to time limits on welfare reduced mortality. We found instead they increased mortality. (more…)
