Chung-Jung Chiu DDS PhD Scientist II, JM USDA Human Nutrition Research Center on Aging Assistant Professor, School of Medicine Tufts University Boston MA 02111MedicalResearch.com Interview with: Chung-Jung Chiu DDS PhD Scientist II, JM USDA Human Nutrition Research Center on Aging Assistant Professor, School of Medicine Tufts University Boston MA 02111 MedicalResearch.com: What are the main findings of the study? Answer: In this study, we found that advanced age-related macular degeneration (AMD) is predictable by using clinically readily available information. We devised a simple algorithm to summarize the clinical predictors and showed the validity of our prediction model in both clinic-based and community-based cohorts. We also develop an application (App) for the iPhone and iPad as a practical tool for our prediction model. (more…)

Dr. Ladhani: Pregnancy was associated with an increased of serious infection by a bacterium called Haemophilus influenzae which is usually associated with respiratory tract infections. Nearly all the H. influenzae were unencapsulated; that is, they did not have an outer sugar capsule which is often required to make the bacterium more virulent. The encapsulated H. influenzae type b (Hib), for example, was the most common cause of bacterial meningitis in your children prior to routine immunisation. We also found that infection with unencapsulated H. influenzae was associated with poor pregnancy outcomes, including miscarriages, stillbirth and premature birth. (more…)

Marc Righini, MD Division of Angiology and Hemostasis Geneva University Hospital, Geneva, SwitzerlandMedical Research.com Interview with: Marc Righini, MD Division of Angiology and Hemostasis Geneva University Hospital, Geneva, Switzerland   MedicalResearch.com: What are the main findings of this study? Dr. Righini: The study shows that when compared with a fixed D-Dimer cutoff of 500 ng/ml, the combination of pretest clinical probability assessment with age-adjusted D-dimer cut-off was associated  with a larger number of patients in whom Pulmonary Embolism  could be excluded, with a low likelihood of recurrent VTE. The benefit was the most important in patients  75 years or older, in whom using the age-adjusted cutoff instead of the 500 ng/ml cutoff increased five-fold the proportion of patients in whom PE could be excluded on the basis of D-dimer measurement.

Willer, PhD Assistant Professor Division of Cardiovascular Medicine, Dept of Internal Medicine Dept of Human GeneticsDept of Computational Medicine and Bioinformatics University of Michigan Ann Arbor, MI 48109-5618 MedicalResearch.com: What are the main findings of the study? Dr. Willer: We wanted to find new genes related to heart disease, so we examined the DNA of approximately 10,000 Norwegian individuals and found 10 genes that are important regulators of blood cholesterol levels. Nine of these were well known to be related to lipids, but one gene was new.  It turned out to be in a region we'd previously noticed to be related to cholesterol, but it was a big region and we hadn't been able to pinpoint the gene yet.  Using this new approach, focusing on DNA differences that result in slightly different proteins in people, we zeroed in on the gene.  We then altered this gene in mice, and saw the predicted changes in cholesterol levels in mice.

Yanzhuang Wang, PhD Associate professor Dept. of Molecular, Cellular and Developmental Biology and Dept. of Neurology University of Michigan Ann Arbor, MI 48109-1048MedicalResearch.com Interview with: Yanzhuang Wang, PhD Associate professor Dept. of Molecular, Cellular and Developmental Biology and Dept. of Neurology University of Michigan Ann Arbor, MI 48109-1048  MedicalResearch.com: What are the main findings of the study? Dr. Wang: We learned how to repair a cellular structure called the Golgi apparatus that is broken in Alzheimer’s disease. This helps us understand how to reduce the formation of the toxic plaques that kill cells in the brain of Alzheimer's patients. The formation of amyloid plaques is a hallmark of Alzheimer’s disease; but exactly how much the plaques contribute to the disease is still not known. Our study found that the broken Golgi in the disease may be a major source of the toxicity of amyloid plaques. We showed in this study that repairing the Golgi can reduce the formation of the toxic plaques and thus may delay the disease development. (more…)

Dr Joe Brierley Great Ormond Street Hospital for Children Ormond Street, London WC1N 3JH, UKMedicalResearch.com Interview with: Dr Joe Brierley Great Ormond Street Hospital for Children Ormond Street, London WC1N 3JH, UK   MedicalResearch.com: What are the main findings of the study? Dr. Brierley: In the UK babies under 2-months of age cannot be verified as having died using ‘neurological criteria,’ due to national guidelines; whereas in North America, Australasia and other European countries his is possible. Because of this no organ donation from those under 2-months occurs in the UK contributing to the lack organs for small children who could benefit from such lifesaving interventions. Our study finds that if the rules were changed to be compatible with other countries their would be a significant yield of organs from one specialist children’s hospital, and likely to be many more nationally.

Dr. Lu Qi: In this study, we for the first time provide reproducible evidence from three large cohort studies to show that the association between regular consumption of fried foods and higher BMI was particularly pronounced among people with a greater genetic predisposition to obesity. On the other hand, the adverse genetic effects on BMI were also amplified by consuming more fried foods, the effects among those who ate fried foods more than four times a week was about twice as large compared with those who ate them less than once a week.

Perrin, MD, MPH Associate Vice Chancellor for Research, and Director, Office of Research Development University of North Carolina at Chapel Hill  and Associate Professor Department of Pediatrics, Division of General Pediatrics and Adolescent Medicine University of North Carolina at Chapel Hill, School of Medicine Chapel Hill, NC 27599-7225 MedicalResearch.com: What are the main findings of the study? Dr. Perrin: The study included a large, diverse sample of 863 low-income parents of two-month-olds participating in Greenlight, an obesity prevention trial taking place at four medical centers: UNC, New York University, Vanderbilt University and the University of Miami.  Among all of the parents, behaviors that are thought to be related to later obesity were highly prevalent. Exclusive formula feeding was more than twice as common (45 percent) as exclusive breastfeeding (19 percent). Twelve percent had already introduced solid food, 43 percent put infants to bed with bottles, 23 percent propped bottles instead of holding the bottle by hand (which can result in overfeeding), 20 percent always fed when the infant cried, and 38 percent always tried to get their children to finish their milk.  In addition, 90 percent of the infants were exposed to television and 50 percent actively watched TV (meaning parents put their children in front of the television in order to watch).  There were differences in these behaviors by race and ethnicity, and study results show that culturally-tailored counseling should be offered to parents of different backgrounds who may feed and play with their children differently.

Dr. Maarten de Rooij MD, PhD Candidate Department of Radiology, Radboud University Nijmegen Medical Centre, Nijmegen, Gelderland 6525 GA, The NetherlaMedicalResearch.com Interview with: Dr. Maarten de Rooij MD, PhD Candidate Department of Radiology Radboud University Nijmegen Medical Centre Nijmegen, Gelderland 6525 GA, The Netherlands   MedicalResearch.com: What are the main findings of the study? Dr. de Rooij : Prostate cancer is the most common cancer in men and the second leading cause of cancer related death. The current diagnosis is based on ‘random or blind’ systematic transrectal ultrasound guided prostate biopsies in men with an elevated PSA. This can lead to over-diagnosis and over-treatment of prostate cancer, but can also miss important tumors. The role of multiparametric MRI (mpMRI) to improve the diagnosis of prostate cancer is evolving. In this meta-analysis we determined the diagnostic accuracy of mpMRI for the detection of prostate cancer. Our analysis included 7 studies using mpMRI which showed high overall specificity (0.88; 95% CI 0.82-0.92), with variable but high negative predictive values (0.65 - 0.95) and sensitivities (0.74; 95% CI 0.66-0.81).

MedicalResearch.com Interview with: Dr. Atul Shinagare MD Department of Radiology and Center for Evidence-Based Imaging, Brigham and Women’s Hospital, Harvard Medical School, 75 Francis St, Boston, MA 02115Dr. Atul Shinagare MD Department of Radiology and Center for Evidence-Based Imaging, Brigham and Women’s Hospital, Harvard Medical School, 75 Francis St, Boston, MA 02115 MedicalResearch.com: What are the main findings of the study? Answer: We evaluated 100 randomly selected patients from a cohort of 1771 patients evaluated for asymptomatic hematuria in 2004 at our institution in order to assess physician adherence to the 2001 American Urological Association (AUA) guidelines for evaluating patients and its impact on the diagnosis of urologic cancer. We found that most (64%) patients were not evaluated according to the guidelines, that there was substantial variation in the evaluation, and that the evaluation depended largely on the type of hematuria and physician specialty. Only 5% of patients were found to have urologic cancer, and all of them were evaluated according to the guidelines. No additional urologic cancers were diagnosed in patients in whom guidelines were not followed; however, since not all patients were tested thoroughly, occult malignancies may have been present.

MedicalResearch.com Interview with: Dr Rachel J Sacks Jefferiss Wing,  St Mary's Hospital Imperial College Healthcare NHS Trust, London UK MedicalResearch.com: What is the background of this study? Dr. Sacks: 2247 anonymous questionnaires were completed by young women, aged 13-19 years old, attending sexual health services across England, looking at their HPV vaccination outcomes and prevalence of risk factors associated with HPV acquisition and cervical cancer development, and comparing the survey results with national data where available. Known HPV acquisition and cervical cancer development risk factors include cigarette smoking, early age at first intercourse, increasing number of lifetime partners, co-infection with other sexually transmitted infections. MedicalResearch.com: What are the main findings of the study Dr. Sacks:
  •          Young women, aged 13  to 19 years old attending sexual health services across England had higher prevalence of known risk factors associated with HPV acquisition and cervical cancer development, compared with national data.
  •          Survey respondents had lower HPV vaccination offer and lower HPV vaccination completion rates than nationally.
  •          Subgroups within the survey respondents were identified as having a significantly lower offer and significantly lower completion rate of the HPV vaccination. These subgroups included respondents from London, those of non-white ethnicities, 17 to 19 year olds, smokers and those not in education, employment or training (NEETs).
  •          The highest risk individuals, in terms of HPV related risk factors, were the least likely to be offered and additional the least likely to complete the HPV vaccination course.
  •          Currently sexual health services in England are not involved in the delivery of the HPV vaccination programme and this is felt to be a huge missed opportunity for the primary prevention of HPV acquisition and its potential sequelae. Sexual health services should be included as a supplementary HPV vaccination delivery site in order to target these particularly vulnerable young women and to increase the success of the HPV vaccination programme in England.

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.

Rajiv Chowdhury MD, PhD Cardiovascular Epidemiologist Department of Public Health and Primary Care University of CambridgeMedicalResearch.com Interview with: Rajiv Chowdhury MD, PhD Cardiovascular Epidemiologist Department of Public Health and Primary Care University of Cambridge MedicalResearch.com: What are the main findings of the study? Dr. Chowdhury: Total saturated fatty acid, whether measured as a dietary intake variable or in the bloodstream as a biomarker, was not associated with coronary disease risk in combining all available prospective observational studies. Similarly, there were non-significant overall associations in the prospective studies that involved assessments of total monounsaturated fatty acids, long-chain omega-3 and omega-6 polyunsaturated fatty acids. However, we found diversity in the observational associations between specific circulating long-chain omega-3 and omega-6 fatty acids with coronary risk, with some evidence that circulating levels of eicosapentaenoic and docosahexaenoic acids (ie, the two main types of long-chain omega-3 polyunsaturated fatty acids), and arachidonic acid are each associated with lower coronary risk. Similarly, within saturated fatty acids, there were positive, however, non-significant associations observed for circulating blood composition of palmitic and stearic acids (found largely in palm oil and animal fats, respectively), whereas circulating margaric acid (a milk fat) had a significant inverse association. Additionally, when we investigated the randomised controlled trials that reported on the effects of omega-3 and omega-6 fatty acids on reducing coronary outcomes, there was no significant overall association observed.

Dr. Hamid: Traditionally patients undergoing diagnostic and interventional coronary artery procedures are kept Nil-by-mouth, but until yet there exists neither evidence nor clear guidance about the benefits of this practice in such patients. In our study performed at two National Health Services (NHS) institutes, we demonstrated in our 1916 patients, that such procedures could be undertaken without the need for being 4-6 hours fasting. None of our patients had major complications leading to pulmonary aspiration or emergency cardiac surgery. (more…)

Associate Chair & Residency Program Director The Reading Hospital Department of OB/GYN Reading, PA  19612-6052 MedicalResearch.com: What are the main findings of the study? Dr. Schnatz: In a subsample of 576 women from the parent WHI CaD (calcium plus vitamin D supplementation)  trial* , there was a significant (38%) increase in mean serum 25OHD3 concentrations after two years (95% CI 1.29-1.47, p< 0.001) for women randomized to CaD (24.3ng/mL vs. 18.2 ng/mL). Women randomized to CaD had a 4.5 mg/dL mean decrease in LDL-C which was statistically significant.  After accounting for serum 25OHD3 concentration, the effect of CaD was attenuated, suggesting that higher concentrations of 25OHD3, in response to CaD supplementation, are associated with improved LDL-C. In observational analyses, higher concentrations of 25OHD3 were associated with significantly higher HDL-C along with significantly lower LDL-C and TG concentrations. * 1,000 mg of elemental calcium plus 400 IU of vitamin D3 daily (more…)

Dr Tobias Teichert Assistant Professor of Psychiatry University of Pittsburgh Pittsburgh, PA 15261MedicalResearch.com Interview with: Dr Tobias Teichert Assistant Professor of Psychiatry University of Pittsburgh Pittsburgh, PA 15261 MedicalResearch.com:  What are the main findings of the study? Dr. Teichert:  "Our study provided three main findings: First, we measured how long it takes subjects to allocate attention to a relevant target and how effectively they can block out the distractors. We found that after 120 msec selective attention is fully engaged and completely blocks out the distractor. Based on this finding, we predicted that subjects should be able to improve decision accuracy by delaying decision onset, and that this should be more effective than simply prolonging the whole decision process. Most importantly, we found that subjects indeed use this more effective way of improving decision onset: On average, subjects delayed decision onset by about 50 msec when we asked them be as accurate as possible. The good news is that people seem to use this more optimal mechanism automatically, without being told to do so and without being aware of what they do. The bad news is that we don’t seem to be using this skill quite as effectively as we could. In our case, subjects could have improved accuracy even further by delaying decision onset by an additional 50 ms. However, taken together, our findings show that decision onset is to some degree under cognitive control, and that we might be able to devise training strategies to harness its full potential” (more…)

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…)
