MedicalResearch.com Interview with:
Nita Ahuja, MD
Departments of Surgery and Oncology,
Johns Hopkins University School of Medicine
Baltimore, Maryland
MedicalResearch.com: What are the main findings of the study?
Dr. Ahuja: Across the nation, laparoscopic colectomy is performed about as frequently as open colectomy, despite being associated with a lower complication rate and a lower overall hospital cost. On the other hand, an exponentially growing prevalence was found with robotic colectomy, a procedure that has so far demonstrated only equivalent outcomes with laparoscopic colectomy but a higher overall cost.
MedicalResearch.com Interview with:
Dr. Ronald C. Petersen M.D., Ph.D.
Division of Epidemiology
Department of Health Sciences Research; Department of Neurology
Mayo Clinic, Rochester, MN
MedicalResearch.com: What are the main findings of the study?
Dr. Petersen: The diagnosis of mild cognitive impairment increases the likelihood of developing dementia.
MedicalResearch.com Interview with:
Mitesh Patel, MD, MBA
RWJF Clinical Scholar, University of Pennsylvania
Mitesh Patel, MD, MBA is a Robert Wood Johnson Clinical Scholar the University of Pennsylvania and primary care physician at the Philadelphia VA Medical Center
MedicalResearch.com: What are the main findings of the study?
Dr. Patel: We evaluated survey responses from nearly 300 internal medicine residency programs directors to assess whether residency programs were teaching residents the fundamental concepts of practicing high-value, cost-conscious care. We found that 85% of program directors feel that graduate medical education has a responsibility to help curtail the rising costs of health care. Despite this, about 6 out of every 7 internal medicine residency programs have not yet adopted a formal curriculum teaching new physicians these important concepts.
MedicalResearch.com Interview with:
Harrys A. Torres, MD, FACP
Assistant Professor, Director of Hepatitis C Clinic
Department of Infectious Diseases, Infection Control and Employee Health
The University of Texas MD Anderson Cancer Center
MedicalResearch.com: What are the main findings of the study?
Dr. Torres: The main findings of the study were that patients with hepatitis C virus (HCV) infection who were successfully treated with antivirals and attained sustained virologic response (SVR) did not have a relapse of HCV infection after receiving immunosuppressive chemotherapy for cancer. Patients in the study received different chemotherapeutic agents, including rituximab and systemic corticosteroids. Durability of SVR was maintained up to 14 years after chemotherapy in cancer patients.
MedicalResearch.com Interview with;
Dr. Wanpen Vongpatanasin, MD
Professor of Medicine
Director, Hypertension Section, Cardiology Division
UT Southwestern Medical Center
MedicalResearch.com: What are the main findings of the study?
Dr. Vongpatanasin: We found that more than 50% of patients with resistant hypertension were non-adherent to at least one drug prescribed by their primary care physicians for blood pressure control.
When we provided this information back to the patients, as part of care in our hypertension specialty clinic, we found that many patients report difficulty taking prescribed medications due to either associated side effects or cost of the medication. When we adjusted patient's medications to fit their needs, BP levels were substantially improved during subsequent visits without increasing the number of medications.

Dr. Thomas: This population of severely obese individuals (mean BMI 47kg/m2) from a regional specialist weight management service poor sleep quality (Pittsburgh Sleep Quality Index, PSQI) and daytime sleepiness (Epworth Sleepiness Scale) were strongly associated with poorer quality of life (Impact of Quality of Life-Lite (IWQOL-Lite)
MedicalResearch.com Interview with:
J. Randall Curtis, MD, MPH
Professor of Medicine
Director, UW Palliative Care Center of Excellence
Section Head, Pulmonary and Critical Care Medicine, Harborview Medical CenterA. Bruce Montgomery, M.D. – American Lung Association Endowed Chair in Pulmonary and Critical Care Medicine, University of Washington, Seattle, WA 98104
MedicalResearch.com: What are the main findings of the study?
Dr. Curtis: We examined the effect of a communication-skills intervention for internal medicine and nurse practitioner trainees on patient- and family-reported outcomes. The study was funded by the National Institutes of Nursing Research of the National Institutes of Heatlh. We conducted a randomized trial with 391 internal medicine and 81 nurse practitioner trainees at two universities. Participants were randomized to either an 8-session simulation-based, communication-skills intervention or to usual education. We collected outcome data from a large number of patients with life-limiting illness and their families, including 1866 patient ratings and 936 family ratings. The primary outcome was patient-reported quality of communication and, overall, this outcome did not change with the intervention. However, when we restricted our analyses to only patients who reported their own health status as poor, the intervention was associated with increased communication ratings. Much to our surprise, the intervention was associated with a small but significant increase in depression scores among post-intervention patients. Overall, this study demonstrates that among internal medicine and nurse practitioner trainees, simulation-based communication training compared with usual education improved communication skills acquisition, but did not improve quality of communication about end-of-life care for all patients. However, the intervention was associated with improved patient ratings of communication for the sickest patients. Furthermore, the intervention was associated with a small increase in patients’ depressive symptoms, and this appeared most marked among patients of the first-year residents.
MedicalResearch.com Interview with:
James Guevara, MD, MPH
Associate Professor of Pediatrics & Epidemiology
Senior Diversity Search Advisor, Perelman School of Medicine
University of Pennsylvania,Director of Interdisciplinary Initiatives
PolicyLab: Center to Bridge Research, Practice, & Policy
The Children's Hospital of Philadelphia,Philadelphia, PA 19104
MedicalResearch.com: What did the study attempt to address?
Dr. Guevara: Medical schools have sought to build more diverse faculty in their institutions through faculty development programs targeted to underrepresented minority faculty members. This study was conduct by THE CHILDREN'S HOSPITAL OF PHILADELPHIA'S POLICYLAB and The University of Pennsylvania and sought to determine if there was an association between minority faculty development programs and the representation, recruitment, and promotion of underrepresented minority faculty.
MedicalResearch.com Interview with:
Richard Schwartz, Ph.D.
Professor, Associate Dean for Graduate Academic and Student Affairs College of Natural Science Michigan State University
Department of Microbiology and Molecular Genetics
Michigan State University East Lansing, MI 48824-4320
MedicalResearch.com: What are the main findings of the study?
Dr. Schwartz: The main finding is that exposure to a high fat diet from the age of puberty onwards hastened the development of chemical carcinogen-induced breast cancer in absence of weight gain. We also found that prior to the appearance of any tumors, we could detect changes in the mammary gland that included increased cellular proliferation, increased vascularity, and changes in immune function.
MedicalResearch.com Interview with:
Dr. Victor W. Henderson MD
Professor of Health Research and Policy and of Neurology and Neurological Sciences
Stanford University, Stanford, CA 94305
MedicalResearch.com: What are the main findings of the study?
Dr. Henderson: Estrogen or hormone therapy effects on some health outcomes differ by age, harmful at one age and beneficial at another.
This difference is sometimes referred to as the “critical window” or “timing” theory. It is controversial whether the so-called critical-window applies to memory or other cognitive skills.
In assessing the critical window hypothesis, we found that the relation between blood levels of estrogen and memory or reasoning skills is the same in younger postmenopausal women as in older postmenopausal women. Essentially, there is no association at either age.
MedicalResearch.com Interview with:
Craig A Umscheid, MD, MSCE, FACP
Assistant Professor of Medicine and Epidemiology
Director, Center for Evidence-based Practice
Medical Director, Clinical Decision Support
Chair, Department of Medicine Quality Committee
Senior Associate Director, ECRI-Penn AHRQ Evidence-based Practice Center
University of Pennsylvania Philadelphia, PA 19104
MedicalResearch.com: What are the main findings of the study?
Dr. Umscheid: We developed and successfully deployed into the electronic health record of the University of Pennsylvania Health System an automated prediction tool which identifies newly admitted patients who are at risk for readmission within 30 days of discharge. Using local data, we found that having been admitted to the hospital two or more times in the 12 months prior to admission was the best way to predict which patients are at risk for being readmitted in the 30 days after discharge. Using this finding, our automated tool identifies patients who are “high risk” for readmission and creates a “flag” in their electronic health record (EHR). The flag appears next to the patient’s name in a column titled “readmission risk.” The flag can be double-clicked to display detailed information relevant to discharge planning. In a one year prospective validation of the tool, we found that patients who triggered the readmission alert were subsequently readmitted 31 percent of the time. When an alert was not triggered, patients were readmitted only 11 percent of the time. There was no evidence for an effect of the intervention on 30-day all-cause readmission rates in the 12-month period after implementation.
MedicalResearch.com Interview
Dr. Michael Shevell
Chair of the Pediatrics Department at the McGill Faculty of Medicine and Pediatrician-in-Chief at the Montreal Children’s Hospital and the McGill University Health Centre
MedicalResearch.com: What are the main findings of the study?
Dr. Shevell: At risk term infants who have spent some time in a Level III NICU after birth are at substantially increased later risk for an autistic spectrum disorder. Frequently this disorder occurs in conjunction with substantial co-morbidity.
MedicalResearch.com Interview with:
Prof Ype Elgersma PhD
Professor, Neuroscience
Neuroscience Institute, Erasmus University Rotterdam
Rotterdam, Netherlands
MedicalResearch.com: What are the main findings of the study?
Answer: Research in genetic mouse models suggested that inhibition of HMG-CoA-reductase by statins might ameliorate the cognitive and behavioral phenotype of children with Neurofibromatosis type 1 (NF1), an autosomal dominant disorder. In a 12-month randomized placebo-controlled study including 84 children with NF1, we found that simvastatin, an inhibitor of the HMG-CoA-reductase pathway had no effect on full-scale intelligence, attention problems or internalizing behavioral problems, or on any of the secondary outcome measures.
MedicalResearch.com Interview with:
Dr. Jinoos Yazdany MD, MPH
Assistant Professor in Residence
UCSF School of Medicine
MedicalResearch.com: What are the main findings of the study?
Answer: For almost all of the drugs we examined, we found that less than half of patients adhered to treatment. For some drugs, less than one-third of individuals were adherent. The average medication possession ratios were low across all drugs.
We found that several factors played an important part in adherence. Younger individuals were less likely to adhere to treatment for several drugs, and we also found racial/ethnic differences, with Black, Hispanic and Native populations having lower adherence. We also found geographic variation in adherence, with individuals in the Northeast being the most likely to adhere to treatment.
MedicalResearch.com Interview with:
Ilke Sipahi, MD
Department of Cardiology
Acibadem University Medical School, Istanbul, Turkey
Harrington Heart and Vascular Institute, University Hospitals Case Medical Cente, Case Western Reserve University School of Medicine, Cleveland, Ohio
MedicalResearch.com: Were you surprised at the extreme difference between these 2 analyses?
Answer: I was surprised. However, it is not unusual to find completely
contradictory results in medical studies. I was more surprised at the
fact that FDA paid more attention to it administrative observational
dataset rather than the huge large randomized clinical trials, all
showing excess GI bleeds with dabigatran (Pradaxa). Anyone who is even
slightly familiar with the medical literature knows that randomized trials are the gold standard in medical studies.
MedicalResearch.com Interview with:
Dr. Kelly K. Hunt, M.D., F.A.C.S.
Professor, Department of Surgical Oncology, Division of Surgery
Chief, Breast Surgical Oncology Section, Department of Surgical Oncology
The University of Texas MD Anderson Cancer Center, Houston, TX
MedicalResearch.com: What are the main findings of the study?
Dr. Hunt: The primary endpoint of the Z1041 trial was the proportion of patients who had pathological complete response in the breast, defined as the percentage of women who started the neoadjuvant treatment with no histological evidence of disease in the breast at surgery. We found that high pathologic response rates were observed in both treatment groups with similar cardiac safety profiles in both arms of the trial. Specifically, 56.5% of patients in the sequential group (fluorouracil, epirubicin and cyclophosphamide on day one of a 21-day cycle for four cycles followed by paclitaxel plus trastuzumab weekly for 12 weeks) had a complete pathological response versus 54.2% of the patients who received the concurrent regimen (paclitaxel and trastuzumab weekly for 12 weeks followed by fluorouracil, epirubicin and cyclophosphamide on day one of a 21-day cycle with trastuzumab on days one, eight and 15 of the 21-day cycle for four cycles). The difference in pathologic complete response rates between the treatment arms was not statistically significant. Cardiac safety was a secondary endpoint of the trial and we found that both regimens had acceptable cardiac safety profiles.

MedicalResearch.com Interview with:
James Murphy, M.D.
Assistant Professor, Department of Radiation Medicine and Applied Sciences, Center for Advanced Radiotherapy Technologies ,UC San Diego Moores Cancer Center
La Jolla, CA 92093
MedicalResearch.com: What are the main findings of the study?
Dr. Murphy: This study evaluated racial disparity in metastatic colorectal cancer. In a large population-based cohort we found of over 11,000 patients we found that black patients were less likely to be seen in consultation by a cancer specialist, and were less likely to receive treatment with chemotherapy, surgery, or radiation. Furthermore, we found that this disparity in treatment accounted for a substantial portion of the race-based differences between black and white patients.
MedicalResearch.com Interview with:
Yogesh Moradiya MBBS
From the Neurosciences Critical Care Division
Johns Hopkins University, Baltimore, MD;
MedicalResearch.com: What are the main findings of the study?
Answer: We studied 712,433 stroke cases in 6,839 hospital samples in United States over 11-year study period (2000-2010) and found that hospitals with neurology residency training program treated stroke patients with tissue plasminogen activator (tPA) more frequently than other teaching or non-teaching hospitals. The higher tPA utilization in hospitals with neurology residencies was independent of patient age, gender, ethnicity, insurance status, comorbidities, hospital geographic location, stroke case volume, calendar year and the Joint Commission Primary Stroke Center certification.

MedicalResearch.com Interview with:
Dr. Laurent Azoulay
Project Leader, Lady Davis Institute
Assistant Professor, Department of Oncology, McGill University
MedicalResearch.com: What are the main findings of the study?
Dr. Azoulay: Using large population-based databases from the UK, we assembled a cohort of men newly-diagnosed with non-metastatic prostate cancer. Within this group of men, the use of statins after prostate cancer diagnosis was associated with a 24% decreased risk in cancer-related mortality. We observed duration- as well as a dose-response relationships. Furthermore, in a secondary analysis, we observed that the benefits were greater among men who used also used statins before their diagnosis, with more modest yet significant benefits among men who initiated the treatment after their diagnosis. The latter result is one of the novelties of this study, as it provides an estimate of the potential benefits of statins, if used in the adjuvant setting.
