Dr. Courtney Lyles Ph.D. Assistant Professor UCSF School of MedicineMedicalResearch.com Interview with: Dr. Courtney Lyles Ph.D. Assistant Professor UCSF School of Medicine Medical Research: What is the background for this study? What are the main findings? Dr. Lyles: In our commentary (http://www.plosmedicine.org/article/info%3Adoi%2F10.1371%2Fjournal.pmed.1001852), we describe the Meaningful Use program sponsored by the federal government to incentivize healthcare systems to implement electronic health records (EHRs).  This Meaningful Use program also includes financial incentives for healthcare systems who can get substantial proportions of their patient population to access their electronic health records – that is, by logging into an online patient portal website to view medical information like lab results or immunization lists or to perform a healthcare task like requesting a medication refill or messaging their provider.  Because there are billions of dollars at stake in this program for EHR implementation, there is a lot of attention on this issue right now.  Many thought leaders are discussing how we can transform healthcare by digitizing medical information and connecting with patients in their everyday life outside of office or hospital visits.  Portals are key to a lot of changes we might make in healthcare delivery in an attempt to increase convenience and satisfaction for patients.  Perhaps most importantly, these online portal websites are also one of the first health technologies that will be relatively uniformly distributed across healthcare settings, from private doctor’s offices to public clinics/hospitals serving vulnerable patient populations. However, our main message is that we in the medical and healthcare fields should be paying more attention to how patients are able to understand and use the information provided through portal websites.  There is a lot of evidence that patients who have lower education/income, are from racial/ethnic minority groups, or have limited health literacy are significantly less likely to use the existing portal websites.  There is also evidence that portal websites are not extremely usable or accessible, which is an additional barrier for those with communication barriers like lower literacy or limited English proficiency.  Therefore, we don’t want widespread EHR implementation to result in only the most well-resourced individuals gaining the potential benefits of portal access.

Reynold A. Panettieri, Jr., M.D. Robert L. Mayock and David A. Cooper Professor of Medicine Pulmonary, Allergy & Critical Care Division Director, Airways Biology Initiative Deputy Director, Center of Excellence in Environmental Toxicology Adjunct Professor, Wistar Institute Philadelphia, PA  19104-3413MedicalResearch.com Interview with: Reynold A. Panettieri, Jr., M.D. Robert L. Mayock and David A. Cooper Professor of Medicine Pulmonary, Allergy & Critical Care Division Director, Airways Biology Initiative Deputy Director, Center of Excellence in Environmental Toxicology Adjunct Professor, Wistar Institute Philadelphia, PA  19104-3413 Medical Research: What is the background for this study? What are the main findings? Dr. Panettieri: Over the past ten years in the US, unconventional gas and oil drilling (hydraulic fracturing) to generate natural gas has markedly increased.  In areas with hydraulic fracturing, there is a large increase in truck traffic, noise and potential air and water pollution.  Accordingly, residents may experience health consequences from such exposures.  We questioned whether proximity to active wells increases hospitalization rates in residents.  To address this question, we reviewed all hospitalizations in two counties in Pennsylvania, namely, Bradford and Susquehanna Counties, that experienced a meteoric increase in active wells.  In comparison, Wayne County, where there is a moratorium on hydraulic fracturing, is demographically identical to Bradford and Susquehanna Counties and served as a control population.  Having examined the 25 most common reasons for admission to the hospital, we determined that cardiovascular hospitalizations as well as neurologic, dermatologic and cancer hospitalizations were associated with living closer to active wells.  These data represent some of the first studies to associate active well drilling with hospitalizations in the United States.

MedicalResearch.com Interview with: Byung-Joo Park, MD, MPH, PhD Professor Department of Preventive Medicine Seoul National University College of Medicine Medical Research: What is the background for this study? What are the main findings? Response: Antidepressants and NSAIDs are each thought to increase the risk of abnormal bleeding.  However, previous studies found neither antidepressants nor NSAIDs alone to be associated with an increased risk of intracranial haemorrhage.  Our research found that combined use of NSADIs in antidepressant users showed the increased relative risk of intracranial haemorrhage risk within the initial 30-days of combined use.

MedicalRDr Yeow Tee Goh Department of Haematology Singapore General Hospital Republic of Singaporeesearch.com Interview with: Dr Yeow Tee Goh MBBS Department of Haematology Singapore General Hospital Republic of Singapore Medical Research: What is the background for this study? What are the main findings? Dr. Goh: Relapsed or refractory peripheral T-cell lymphoma after conventional chemotherapy is associated with a very poor prognosis and there is currently no recommendation on the standard approach to helping these patients. Novel targeted treatments for relapsed or refractory peripheral T-cell lymphoma such as romidepsin, pralatrexate, belinostat, and brentuximab vedotin has been approved by the US Food and Drug Administration (FDA) based on the results of their Phase II studies. With the exception of the remarkable efficacy of brentuximab vedotin in systemic anaplastic large cell lymphoma (86% of patients responding to treatment), the efficacy of romidepsin, pralatrexate, and belinostat in relapsed or refractory peripheral T-cell lymphoma is only modest with objective response rates between 25% and 29%. To our knowledge, no other clinical study has reported on the use of novel combination of targeted agents in in relapsed or refractory peripheral T-cell lymphoma. In our study, Of 23 patients assessable for responses, 10 (43%, 95% CI 23–63) patients had an objective response, of which 5 were complete responses. The combined proteasome and histone deacetylase inhibitor treatment shows promising activity for patients with peripheral T-cell lymphoma.

MedicalResearch.com Interview with: Hubert W. Vesper, PhD Director, Clinical Standardization Programs in the National Center for Environmental Health, Centers for Disease Control and Prevention Co-author, “Measuring Estrogen Exposure and Metabolism: Workshop Recommendations on Clinical Issues” Co-chair of the PATH Steering Committee Medical Research: What is the background for this study? What are the main findings? Dr. Vesper: Accurate data on estrogen levels are needed to ensure appropriate and effective patient care. Research studies found high inaccuracies among different estrogen tests, especially at low estrogen levels commonly observed in postmenopausal women, men and children. Accurate estrogen measurements can be achieved through standardization. Stakeholders should support standardization efforts of the Centers for Disease Control and Prevention (CDC) or alternative strategies to arrive at estrogen measurement methods that are accuracy-based and reliable.

Dr. Ankur Pandya Ph.D. Assistant Professor of Health Decision Science Department of Health Policy and Management Harvard T.H. Chan School of Public Health Boston, MA MedicalResearch.com Interview with: Dr. Ankur Pandya Ph.D. Assistant Professor of Health Decision Science Department of Health Policy and Management Harvard T.H. Chan School of Public Health Boston, MA Medical Research: What is the background for this study? What are the main findings? Dr. Pandya: The American College of Cardiology and the American Heart Association (ACC-AHA) cholesterol treatment guidelines were controversial when first released in November 2013, with some concerns that healthy adults would be over-treated with statins. We found that the current 10-year ASCVD risk threshold (≥7.5%) used in the ACC-AHA cholesterol treatment guidelines has an acceptable cost-effectiveness profile (incremental cost-effectiveness ratio of $37,000/QALY), but more lenient ASCVD thresholds would be optimal using cost-effectiveness thresholds of $100,000/QALY (≥4.0%) or $150,000/QALY (≥3.0%).

Diana W. Bianchi, M.D. Executive Director, Mother Infant Research Institute Vice Chair for Research and Academic Affairs, Department of Pediatrics Tufts Medical CenterMedicalResearch.com Interview with: Diana W. Bianchi, M.D. Executive Director, Mother Infant Research Institute Vice Chair for Research and Academic Affairs Department of Pediatrics Tufts Medical Center Medical Research: What is the background for this study? What are the main findings? Response: Noninvasive Prenatal Testing (NIPT) is the fastest growing genetic test. It has been available since late 2011. Over 2 million tests have been performed worldwide. Cancer in pregnancy is rare, and only occurs in 1 in 1,000 pregnant women. About 0.2 per cent of noninvasive prenatal tests that use sequencing of maternal plasma DNA have a so-called “false positive” result. In most cases this is not an error, but there is a biological explanation for the discrepancy between the abnormal noninvasive prenatal test result and a normal fetal chromosome result obtained from a diagnostic procedure, such as amniocentesis or chorionic villus sampling (CVS). We are very interested in the underlying biological explanations for the false positive cases, and it turns out that a clinically silent tumor in the mother is one of them. The mother’s tumor is shedding DNA into her blood that is detected by the prenatal test. In a large clinical dataset of over 125,000 pregnant women who had a DNA sequencing screen for fetal chromosome abnormalities there were 10 women who were subsequently found to have cancer. We retrospectively analyzed the DNA sequencing results in 8 of these women and found that they had abnormalities in multiple areas of the genome, suggesting that it was DNA from the tumor that was shed into the maternal blood and being detected by the prenatal screen. The noninvasive prenatal sequencing test result that was most suggestive of a cancer risk was the presence of more than one aneuploidy. This finding was present in 7 of the 10 women who had cancer. In three of the eight women we studied it was the abnormal prenatal test result that triggered a subsequent work-up that led to the diagnosis of cancer.

MedicalResearch.com Interview with: Dr. Ángel Chamorro Director, Comprehensive Stroke Center Hospital Clinic Barcelona, Spain Medical Research: What is the background for this study? What are the main findings? Dr. Chamorro: There is a great need of new therapies in patients with acute stroke and our study is based on the clinical observation that patients with acute stroke recover better if at the time of the stroke the levels of uric acid are increased in their blood. That first observation led to a long way of research and administrative challenges but we finally came out with a solution of uric acid (a potent antioxidant) manufactured according to the strict rules which apply to drugs aimed for human use. Thus, we performed a pilot study that showed that uric acid could be safely administered to these patients. We then performed a larger clinical trial in 421 patients which provided very encouraging results overall. Now we are reporting in the Stroke journal appearing on July 9, that women obtained a much greater benefit than men because they had lower levels of uric acid than men because estrogens (female hormones) are efficient excretors of uric acid. In consequence, women were in greater need of uric acid replenishment following the stroke than men.

MedicalResearch.com Interview with: David Jimenez PhD, FCCP Respiratory Department and Medicine Department Ramon y Cajal Hospital IRYCIS, and Alcala de Henares University Madrid Spain Medical Research: What is the background for this study? What are the main findings? Dr. Jimenez: Normotensive patients that have an estimated high-risk for pulmonary embolism (PE)-related complications (i.e., intermediate-risk PE) might benefit from surveillance in an intensive care setting or from the administration of specific advanced therapy. The Bova score was developed for identifying these patients. This study confirms the validity and reproducibility of the Bova score.

MedicalResearch.com Interview with: Wei-Che Chiu, MD, PhD National Taiwan University College of Public Health, Cathay General Hospital and Fu Jen Catholic University Taipei, Taiwan Medical Research: What is the background for this study? Response: Diabetes mellitus is a common risk factor for dementia and accounts for 6–8% of all cases of dementia in older populations. Cognitive impairment is associated with the presence of diabetic complications and diabetic severity, but the effects of diabetic severity on dementia are unclear. Our study was to investigate the association between the severity and progress of diabetes and the risk of dementia. Medical Research: What are the main findings? Response: The diabetic severity and progression reflected the risk of dementia, and the early progress in diabetic severity could predict the risk of dementia in new-onset diabetic patients.

Darius A. Paduch, MD, PhDAssociate  Professor of Urology and Reproductive Medicine Director Sexual Health and Medicine Research Director of Male Infertility Fellowship Co-Director Male Infertility Genetics Laboratory Weill Cornell Medical College Dept of Urology New York, NY 10065MedicalResearch.com Interview with: Darius A. Paduch, MD, PhD Associate  Professor of Urology and Reproductive Medicine Director Sexual Health and Medicine Research Director of Male Infertility Fellowship Co-Director Male Infertility Genetics Laboratory Weill Cornell Medical College Dept of Urology New York, NY 10065 Medical Research: What is the background for this study? What are the main findings? Dr. Paduch: Ejaculatory dysfunction, inability to ejaculate or delayed ejaculation affects 10-8% of men. Inability to ejaculate either intravaginally or at all is independent of erectile function. Men with normal erection may take very long time to ejaculate (>30 min) or not able to ejaculate at all. The men in our study had either normal erections or minimal erectile dysfunction. Men of all ages have spontaneous erections but don't ejaculate just from erection, it is progression of arousal and activation of spinal cord motor generator for ejaculation which is necessary for ejaculation. One of important factors in our ability to ejaculate is testosterone (T), testosterone allows for normal function of CNS centers for ejaculation, it is a modulator and is necessary; preadolescent boys don't ejaculate because their spinal cord centers for ejaculations are not mature – process dependent on testosterone. However testosterone is just one of many neurotransmitters and hormones needed of normal ejaculation. Actually our study showed that in men who achieved normal levels of testostosterone the ejaculatory function have improved. As this was first double blinded and randomized clinical trial we had to report our results based on radomization to testosterone treatment or placebo. Unfortunately only 70-80% of men treated with topical testosterone preparation will achieve normal testosterone level , we simply didn’t reach statistical significance based on randomization and  considering relatively low number of patients in each group. But in men who achieved normal testosterone levels the difference was statistically significant. Testosterone should not be used to treat any conditions, including ejaculatory dysfunction, in absence of low testosterone  level. EjD is very common but it bares significant embarrassment stigma, it is difficult for the couple to bear fact that male partner can’t ejaculate, it also creates issues within couple and question about attraction and fidelity. We have previously showed that treatment with tadalafil improves ejaculatory and orgasmic dysfunction and these data has been published. This study was focused on effect of testosterone, but its main significance was it’s design: we developed new tools to assess ejaculatory function and learned a lot about when patients or their partners start to be bothered by EjD. If time to ejaclate takes > 30 min We are now looking into novel and available pharmacotherapy modulating dopaminergic and canabioid signaling and reward mechanisms. I am also very excited about our potential work in direct spinal cord motor generator nano stimulator, this could be very useful for men with spinal cord injuries and diabetic patients. We paved the road for others and I am sure new treatments are just a matter of time.

What are the main findings? Dr. Choudhry: Intestine is the major reservoir of bacteria in the body. We observed that gut bacterial composition is altered after burn injury. We found that burn causes a significant increase in Enterobacteriaceae, a group of bacteria that has the potential to be harmful for the host. Dysbiosis of the healthy intestinal microbiome is associated with a number of inflammatory conditions.

MedicalResearch.com Interview with: Junichi Nishimura MD, PhD Assistant professor Osaka University in Japan Medical Research: What is the background for this study? What are the main findings? Dr. Nishimura: Oxaliplatin is classified as moderately emetogenic chemotherapy and 2-drug combination antiemetic therapy is recommended for Oxaliplatin based chemotherapy including FOLFOX and XELOX in all guidelines for antiemesis. Nausea and vomiting are still frequent adverse events which decrease the patient’s QOL. However, there was no study investigating whether 3-drug combination antiemetic therapy (5HT3 receptor antagonist+dexamethasone+aprepitant) reduce chemotherapy-induced nausea and vomiting. In this study, we conducted a multicentre, randomized phase III study to evaluate the usefulness of the combined use of aprepitant in colorectal cancer patients treated with Oxaliplatin based chemotherapy. In this phase III study, 3-drug combination therapy significantly increased the inhibition rate of vomiting which was the primary endpoint of this study. Moreover, the inhibition rate of nausea, complete response (no vomiting and no rescue medication use), and complete protection (no vomiting , no rescue medication use and no moderate or worsened nausea) was significantly higher in aprepitant group in overall and delayed phase. We, next, compared the inhibition of vomiting and nausea between males and females in delayed phase. When patients were grouped by sex regardless of the assigned treatment group, females were more affected by nausea and vomiting than males. Finally, in female, aprepitant did significantly prevent nausea and vomiting as well as increased chance of complete protection.

MedicalResearch.com Interview with: Jennifer Mack, MD, MPH Pediatric oncologist Dana-Farber/Boston Children’s Cancer and Blood Disorders Center  Medical Research: What is the background for this study? What are the main findings?  Dr. Mack:  This study evaluated the intensity of end-of-life care received by adolescents and young adults (AYAs) with cancer. Little was previously known about the kind of end-of-life care these young patients receive. We evaluated the care of 663 Kaiser Permanente Southern California patients who died between the ages of 15 and 39 between the years 2001 and 2010. We found that more than two-thirds of adolescents and young adults received at least one form of intensive end-of-life care before death. This includes chemotherapy in the last two weeks of life (11%), more than one emergency room visit in the last month of life (22%), intensive care unit care in the last month of life (22%), and hospitalization in the last month of life (62%). Medical Research: What should clinicians and patients take away from your report? Dr. Mack:  A majority of dying young people with cancer receive intensive measures at the end of life. Older patients who know they are dying usually do not want to receive intensive measures, which are associated with a poorer quality of life near death. High rates of intensive measures raise the concern that young people may experience unnecessary suffering at the end of life. However, it is also important to recognize that adolescents and young adult patients may have different priorities than older patients, and may be more willing to accept intensive measures in order to live as long as possible. Clinicians, patients, and family members should talk about what is most important to patients at the end of life so that their values can be upheld, whether patients prioritize doing everything possible to live as long as possible or focus on quality of life.   Medical Research: What recommendations do you have for future research as a result of this study?  Dr. Mack:  Future research should further examine end-of-life decision-making for adolescents and young adults, including the reasons for receipt of intensive measures.

Amol Narang MD Radiation Oncology Resident Johns Hopkins MedicineMedicalResearch.com Interview with: Amol Narang MD Radiation Oncology Resident Johns Hopkins Medicine Medical Research: What is the background for this study? What are the main findings? Dr. Narang: The care provided to cancer patients at end-of-life can be intense, including frequent ER visit, hospitalizations, and ICU stays in the last month of life, administration of chemotherapy in last two weeks of life, and late referrals to hospice. Providing high-intensity treatments at end-of-life has been associated with reduced patient quality-of-life and increased caregiver bereavement. Advance care planning represents an opportunity for patients to indicate their preferences for end-of-life care to try to ensure that the care that they receive at end-of-life is consistent with their values, and has been endorsed by oncologic professional societies, such as ASCO and the NCCN. As such, we wanted to assess if oncologists’ long-standing recognition of the merits of advance care planning has translated into increased participation in advance care planning by cancer patients, and to determine which forms of advance care planning are associated with intensity of care given at end-of-life. From 2000-12, we found that the only type of advance care planning that increased was the assignment of a power of attorney (52% in 2000 to 74% in 2012). However, having a power of attorney was not associated with receiving less aggressive end-of-life care. On the other hand, having a living wills and engaging in a discussion with a provider or loved one about preferences for end-of-life care were both associated with reduced treatment intensity. However, the frequency with which cancer patients created a living or discussed their preferences for end-of-life care did not increase over the study period; importantly, 40% of patients dying of cancer never communicated their preferences for care at end-of-life with anyone.

Robert J. Lewandowski, MD FSIRAssociate Professor of Radiology Director of Interventional Oncology Department of Radiology Northwestern University Feinberg School of MedicineMedicalResearch.com Interview with: Robert J. Lewandowski, MD FSIR Associate Professor of Radiology Director of Interventional Oncology Department of Radiology Northwestern University Feinberg School of Medicine Medical Research: What is the background for this study? What are the main findings? Response: Retrievable inferior vena cava filters (rIVCF) were designed to provide temporary prevention from pulmonary embolism and then be removed when no longer needed. With permanent United States Food and Drug Administration (FDA) indication, these devices now account for the majority of IVC filters placed. Most rIVCFs placed are never removed because of poor clinical follow up, failed retrieval procedures, or patients not being offered the opportunity for filter removal secondary to prolonged dwell time; the latter has previously been correlated with retrieval failure. Retrievable IVCFs appear to be subject to greater device related complications (e.g., filter penetration of the IVC, filter migration, filter fracture) relative to permanent devices; furthermore, the rates of these complications appear to increase with filter dwell time. This prompted the FDA to issue a 2010 safety alert urging removal of rIVCFs once they are deemed no longer necessary. In the present study, we sought to determine whether rIVCF dwell time affects technical success of the retrieval procedure. Over a six-year period, 648 retrieval procedures were performed at our institution, with filter dwell times ranging from 0-108 months. We found that filter dwell time did not negatively impact IVC filter retrieval success nor did it increase our adverse events from the retrieval procedure. With advanced, adjunctive IVC filter retrieval techniques, rIVCFs can be safely and reliably removed despite long dwell times.

What are the main findings? Response: Earlier research identified arterial hypertension as a cause of chronic kidney disease but in older persons the relation between blood pressure and kidney function is little investigated.This study analyses the relation between dynamic blood pressure measurements and kidney function over time. A decline in blood pressure over time turned out to be a strong risk factor for kidney function decline in all age strata.

Jennita Reefhuis, PhD Epidemiologist with CDC National Center on Birth Defects and Developmental DisabilitiesMedicalResearch.com Interview with: Jennita Reefhuis, PhD Epidemiologist with CDC National Center on Birth Defects and Developmental Disabilities Medical Research: What is the background for this study? Dr. Reefhuis: There are previous reports on the link between birth defects and SSRIs. However, the results across some of these studies conflicted. It is not clear whether one SSRI might be safer than other SSRIs. Medical Research: What are the main findings? Dr. Reefhuis: Reassuringly, we found that the five earlier reported links between specific birth defects and sertraline were not found again. We did find that some birth defects occur two to three times more frequently among babies born to mothers who took paroxetine and fluoxetine in early pregnancy.

Prof. Reich: The Phase 2b X-PLORE study compared a new generation biologic therapy, guselkumab - an inhibitor of IL–23, with the anti–tumor necrosis factor (TNF)–alpha agent adalimumab (Humira®) and placebo in the treatment of moderate-to-severe plaque-type psoriasis. It showed that up to 86 percent of patients treated with guselkumab achieved a Physician’s Global Assessment (PGA) score of cleared psoriasis or minimal psoriasis at week 16, the study’s primary endpoint.  Interestingly, levels of efficacy were higher for several guselkumab doses through week 16 when compared to adalimumab. Improvements with guselkumab continued through week 40 with every eight- or twelve-week maintenance treatment.

MedicalResearch.com Interview with: Dr Emanuele Di Angelantonio FESC FAHA University Lecturer | University of Cambridge Director | MPhil in Public Health, University of Cambridge Deputy Director | NIHR Biomedical Research Unit in Donor Health and Genomics Honorary Consultant | NHS Blood and Transplant Department of Public Health and Primary Care Strangeways Research Laboratory Cambridge, UK Medical Research: What is the background for this study? What are the main findings? Response: Previous research as mainly focused on individual with one cardiometabolic condition alone and, despite it could be expected that having more than one condition poses a greater risk, this is the first study that is able to precisely quantify how much is worst. Furthermore, given that the conditions we study (diabetes, heart attack, and stroke) share several risk factors, it could be expected that the combination of these will not be  multiplicative. We were somewhat surprised to find that participants who had 1 condition had about twice the rate of death; 2 conditions, about 4 times the rate of death; and all 3 conditions, about 8 times the rate of death. We  estimated that at the age of 60 years, men with any two of the cardiometabolic conditions studied would on average have 12 years of reduced life expectancy, and men with all three conditions would have 14 years of reduced life expectancy. For women at the age of 60 years, the corresponding estimates were 13 years and 16 years. The figures were even more dramatic for patients at a younger age. At the age of 40 years, men with all three cardiometabolic conditions would on average have 23 years of reduced life expectancy; for women at the same age, the corresponding estimate was 20 years.

Shawn L. Chavez, Ph.D Assistant Scientist/Professor Oregon National Primate Research Center OHSU | Oregon Health & Science UniversityMedicalResearch.com Interview with: Shawn L. Chavez, Ph.D Assistant Scientist/Professor Oregon National Primate Research Center OHSU | Oregon Health & Science University Medical Research: What is the background for this study? Dr. Chavez: This study builds upon a previous study also published in Nature Communications in 2012, which demonstrated that chromosomally normal and abnormal 4-cell human embryos can be largely distinguished by combining the timing intervals of the first three cell divisions with the presence or absence of a dynamic process called cellular fragmentation. The current study further combines time-lapse imaging of embryo development and full chromosome analysis with high throughout single-cell gene expression profiling to assess the chromosomal status of human embryos up to the 8-cell stage. Medical Research: What are the main findings? Dr. Chavez: The key findings of this research were that by measuring the duration of the first cell division, one can identify which embryos are chromosomally normal versus abnormal even earlier in development. By examining gene expression at a single-cell level, we were able to correlate the chromosomal make-up of an embryo to a subset of 12 genes that are activated prior to the first cell division. These genes likely came from either the egg or sperm and can be used to predict whether an embryo will be chromosomally normal or abnormal within the first 30 hours of development.

Response: At least 1 in 1,000 people in the population have a mutation in one of the mismatch repair genes that causes Lynch syndrome. These people have a very high risk of bowel cancer (colorectal cancer): if nothing is done, about half would develop the disease. The main risk reduction method for these people is to have regular colonoscopy screening every year. Almost nothing is known whether or not lifestyle factors and medications can modify the risk of bowel cancer for people with Lynch syndrome. A study was conducted to investigate the associations between aspirin and ibuprofen intake and the risk of bowel cancer, by studying 1,858 people with Lynch syndrome who were recruited into the Colon Cancer Family Registry from Australia, New Zealand, Canada and the USA. This is the largest study to date investigating the associations between aspirin, ibuprofen and bowel cancer risk for people with Lynch syndrome.

What are the main findings? Response: About 2-5% of uterine cancer are associated with an underlying genetic condition mainly Lynch syndrome. Lynch syndrome is caused by a mutation in one of the mismatch repair genes. At least 1 in 1000 people in the population have a mutation that causes Lynch syndrome and these people have a very high risk of cancers mainly bowel and uterine cancers. One in three women with a mutation in one of the mismatch repair genes are likely to develop a uterine cancer in their lifetime. The only way to reduce the risk of uterine cancer for these women is to remove the uterus. There is no current recommendation for screening method to detect uterine cancer early. Almost nothing is known about if and how lifestyle factors and hormonal factors can modify their risk of uterine cancer. By studying 1128 women with a mutation that causes Lynch syndrome who were recruited from Australia, New Zealand, Canada and the USA, we found that later age at first menstrual cycle, having one or more live births, and using hormonal contraceptive use for one year or longer were associated with a lower risk of uterine cancer.

MedicalResearch.com Interview with: Dr. Jürg Bernhard Ph.D. International Breast Cancer Study Group Coordinating Center and Bern University Hospital, Inselspital, Bern, Switzerland Medical Research: What is the background for this study? What are the main findings? Response: In the combined analysis of the SOFT and TEXT trials, the aromatase inhibitor exemestane was more effective than tamoxifen in preventing breast cancer recurrence in young women (premenopausal) who also receive ovarian function suppression (OFS) as adjuvant (post-surgery) treatment for hormone-sensitive early breast cancer, providing a new treatment option for these women. These trials were conducted by the International Breast Cancer Study Group (IBCSG) and involved more than 4700 patients of over 500 centers in 27 countries. Now we present patient-reported quality of life outcomes from these trials. In the TEXT and SOFT trials, patients assigned exemestane+OFS reported more detrimental effects of bone or joint pain, vaginal dryness, greater loss of sexual interest and difficulties becoming aroused, while patients assigned tamoxifen+OFS were more affected by hot flushes and sweats. Global quality of life domains (mood, ability to cope and physical well-being) were similar between the randomized treatment groups.

Mohamed Boutjdir, PhD, FAHADirector of the Cardiovascular Research Program VA New York Harbor Healthcare System Professor, Depts of Medicine, Cell Biology and Pharmacology, State University of New York Downstate Medical Center and NYU School of Medicine, New York, NYMedicalResearch.com Interview with: Mohamed Boutjdir, PhD, FAHA Director of the Cardiovascular Research Program VA New York Harbor Healthcare System Professor, Depts of Medicine, Cell Biology and Pharmacology, State University of New York Downstate Medical Center and NYU School of Medicine, New York, NY Medical Research: What is the background for this study? What are the main findings? Dr. Boutjdir: Patients with autoimmune diseases including Sjogren’s syndrome, systemic lupus erythematosus and other connective tissue diseases who are seropositive for anti-SSA/Ro antibodies may present with corrected QTc prolongation on the surface ECG. This QTc prolongation can be arrhythmogenic and lead to Torsades de Pointes fatal arrhythmia. In our study, we established for the first time an animal model for this autoimmune associated QTc prolongation that is reminiscent of the clinical long QT2 syndrome. We also demonstrated the functional and molecular mechanisms by which the presence of the anti-SSA/Ro antibodies causes QTc prolongation by a direct cross-reactivity and then block of the hERG channel (Human ether-a-go-go-related gene). This hERG channel is responsible for cardiac repolarization and its inhibition causes QTc prolongation. We were able to pinpoint to the target epitope at the extracellular pore forming loop between segment 5 and segment 6 of the hERG channel.

Liana C. Del Gobbo, PhDPostdoctoral Research Fellow Friedman School of Nutrition Science & Policy Tufts University Boston MAMedicalResearch.com Interview with: Liana C. Del Gobbo, PhD Postdoctoral Research Fellow Friedman School of Nutrition Science & Policy Tufts University Boston MA Medical Research: What is the background for this study? What are the main findings? Dr. Del Gobbo: Heart failure most commonly develops in adults over 65 years old- the most rapidly growing portion of the US population. The condition greatly reduces the quality of life of older adults. Heart failure is the leading cause of hospitalizations in the US among those on Medicare, and is associated with large  health care costs. Prevention is key for reducing the burden of this disease. A detailed analysis of factors that might help prevent heart failure, such as a person's pattern of eating (as well as individual foods), in addition to other lifestyle factors (eg. smoking, physical activity, etc), had not been previously examined all together, in the same study. To get a fuller picture of how to prevent this condition, this study examined the relative importance of dietary habits and other lifestyle factors for development of heart failure. Our paper shows that older adults can cut their risk in half by adhering to a few healthy lifestyle factors, including moderate physical activity, modest alcohol consumption (eg. more than one drink/week, but not more than 1-2 drinks/day), not smoking, and maintaining a healthy weight.

Jason Ong, Ph.D., CBSM Associate Professor, Department of Behavioral Sciences Director, Behavioral Sleep Medicine Training Program Rush University Medical CenterMedicalResearch.com Interview with: Jason Ong, Ph.D., CBSM Associate Professor, Department of Behavioral Sciences Director, Behavioral Sleep Medicine Training Program Rush University Medical Center Medical Research: What is the background for this study? What are the main findings? Response: Insomnia is a very common sleep problem that was previously thought to be related to another medical or psychiatric condition.  Evidence now supports the notion that insomnia can emerge as a disorder distinct from the comorbid condition.  In this study, we evaluated the effectiveness of cognitive behavioral therapy for insomnia (CBT-I), the most widely used nonpharmacologic treatment for insomnia, in the context of medical and psychiatric comorbidities. We conducted a systematic review and meta-analysis of 37 studies and found that 36% of patients who received cognitive behavioral therapy for insomnia were in remission at post-treatment compared to 17% who received a control or comparison condition.  CBT-I had medium to large effects for improving sleep quality and reducing the amount of time awake in bed.  Positive findings were also found on the comorbid condition, with greater improvements in psychiatric conditions compared to medical conditions.

Dr. Gary K OwensRobert M. Berne Cardiovascular Research Center University of Virginia, Charlottesville, VirginiaMedicalResearch.com Interview with: Dr. Gary K Owens Ph.D Robert M. Berne Cardiovascular Research Center University of Virginia, Charlottesville, Virginia Medical Research: What is the background for this study? Dr. Owens: The leading cause of death in the USA and worldwide is cardiovascular disease with many of the clinical consequences including heart attacks (myocardial infarctions) and strokes being secondary consequences of atherosclerosis, commonly referred to as hardening of the arteries. Importantly, a heart attack is not caused by gradual narrowing of a large coronary artery by the atherosclerotic plaque, but rather is caused by acute rupture of a plaque that results in a catastrophic thrombotic event that can completely occlude a major coronary artery shutting off blood supply to a major heart region. Similarly, rupture of a plaque can result in formation of a thrombus that breaks off and circulates to a cerebral vessel where it can occlude blood flow to a brain region leading to a stroke. As such, it is critical to understand the mechanisms that regulate the stability of plaques, and the likelihood of plaque rupture. The general dogma among clinicians and cardiovascular researchers has been that atherosclerotic plaques that have an abundance of macrophages and macrophage-derived foam cells relative to smooth muscle cells (SMC), the cells that normally line all of your blood vessels, are less stable and more prone to rupture with subsequent clinical consequences. However, the evidence for this is based on use of methods that are unreliable in identifying which cells within the plaque are truly derived from macrophages versus SMC, and even more importantly, what mechanisms regulate phenotypic transitions of these cells that are critical in the pathogenesis of this disease. Indeed, results of studies in cultured smooth muscle cells and macrophages have shown that each cell can express markers of the other cell type in response to stimuli likely to be present within advanced atherosclerotic lesions while down-regulating expression of their typical cell selective markers. As such, previous studies in the field have likely mis-identified which cell is which in many cases. The goals of our studies were to clearly identify which cells within advanced atherosclerotic lesions are derived from SMC, to determine the various phenotypes exhibited by these cells and their functional role in lesion pathogenesis,  and to determine what regulates these phenotypic transitions.
