MedicalResearch.com Interview with: James K. Rilling, PhD Professor, Anthropology, Psychiatry and Behavioral Science Emory University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: It has been known for a long time that female mammals experience hormonal changes during pregnancy that prepare them to care for their offspring. More recently, it has been shown that some mammalian males, including humans, can also experience hormonal changes that prepare them to care for their offspring. For example, oxytocin levels can increase in human fathers and studies have shown that oxytocin facilitates paternal physical stimulation, play and emotional synchrony with their children. We examined the effects of intranasal oxytocin on brain function in human fathers. We found that intranasal oxytocin increased activation in brain areas involved with reward and empathy when human fathers viewed pictures of their children, but not unknown children. (more…)
Author Interviews, JAMA, Prostate Cancer / 20.02.2017

MedicalResearch.com Interview with: Neeraj Agarwal, MD Associate Professor, Division of Oncology, Department of Medicine University of Utah School of Medicine MedicalResearch.com: What is the background for this study? Response: Biomarkers predicting response to cancer therapy help guide physicians personalize medicine. Significant advances have been made in the development of therapeutic biomarkers in various malignancies, but not in prostate cancer. Dr. Nima Sharifi’s group at the Cleveland Clinic recently discovered that a germline inherited polymorphic variant (1245A→C) in the HSD3B1 gene correlates with shorter duration of response to androgen deprivation therapy (ADT) in hormone sensitive prostate cancer (HSPC). HSD3B1 gene encodes the enzyme 3β-hydroxysteroid dehydrogenase-1 (3βHSD1), which catalyzes adrenal androgen precursors into dihydrotestosterone, the most potent androgen. The authors found that the variant allele of HSD3B1 led to decreased progression-free survival in a dose-dependent manner in post-prostatectomy biochemical recurrence and metastatic HSPC (mHSPC). These results needed external validation before application in the clinic. In our study, we sought to provide the first independent validation of these results in patients with mHSPC. (more…)

MedicalResearch.com Interview with: Yoshifumi Kadono, MD. PhD. Department of Integrative Cancer Therapy and Urology, Kanazawa University Graduate School of Medical Science, Kanazawa, Ishikawa, Japan  MedicalResearch.com: What is the background for this study? What are the main findings? Response: I had experienced some patients who underwent radical prostatectomy (RP) complained penile shortening after RP. Once I checked that kind of reports, some reports mentioned the phenomenon of penile shortening (PS) after radical prostatectomy; however, the results were little bit different and the reasons of PS after RP were not well elucidated. Therefore, we started our study to obtain our data. In our study, the penile length (PL) was measured before, 10 days after, and at 1, 3, 6, 9, 12, 18, and 24 months after RP. And the PL at 10 days after RP was shortest, and it gradually recovered thereafter. Penile length at 12 months after radical prostatectomy was not significantly different from preoperative penile length. Based on MRI investigation, slight vertical repositioning of the membranous urethra after radical prostatectomy caused chronological changes in penile length. (more…)
Author Interviews, Neurological Disorders, Zika / 19.02.2017

MedicalResearch.com Interview with: Ping Wu, MD, PhD John S. Dunn Distinguished Chair in Neurological Recovery Professor, Department of Neuroscience & Cell Biology University of Texas Medical Branch Galveston, TX 77555-0620 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Zika viral infection poses a major global public health threat, evidenced by recent outbreaks in America with many cases of microcephaly in newborns and other neurological impairments. A critical knowledge gap in our understanding is the role of host determinants of Zika-mediated fetal malformation. For example, not all infants born to Zika-infected women develop microcephaly, and there is a wide range of Zika-induced brain damage. To begin to fill the gap, we infected brain stem cells that were derived from three human donors, and found that only two of them exhibited severer deficits in nerve cell production along with aberrant alterations in gene expression.

Author Interviews, Global Health, HIV, Lancet / 19.02.2017

MedicalResearch.com Interview with: Jennifer A. Downs, M.D., Ph.D. Assistant Professor of Medicine and Microbiology & Immunology Department of Medicine Weill Cornell Medicine Center for Global Health New York, NY 10065 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Between 2002 and 2006, three large randomized controlled trials in sub-Saharan Africa demonstrated that male circumcision reduces new HIV infections in men by approximately 60%. Based on these findings, the World Health Organization recommended male circumcision as an HIV prevention strategy in countries with high levels of HIV and a low prevalence of male circumcision. This led to prioritization of 14 countries in Eastern and Southern Africa for massive scale-up of male circumcision beginning in 2011. In many of these countries, the uptake of male circumcision was lower than expected. In northwest Tanzania, where we work, there are a number of barriers to male circumcision. Some of these barriers are cultural, tribal, economic, and religious. We conducted focus group interviews in 2012 that showed that many Christian church leaders and church attenders in our region in Tanzania had major concerns about whether male circumcision was compatible with their religious beliefs. This led us to hypothesize that the uptake of male circumcision could be increased when religious leaders were taught about male circumcision, with the goal that they would then be equipped to discuss this issue with their congregations.

Author Interviews, Biomarkers, Pharmacology, Prostate Cancer / 19.02.2017

MedicalResearch.com Interview with: Teemu J Murtola, MD, PhD, adjunct professor University of Tampere, Faculty of Medicine and Life Sciences Tampere University Hospital, Department of Urology Tampere, Finland MedicalResearch.com: What is the background for this study? Response: A previous study called Prostate Cancer Prevention Trial (PCPT) showed that finasteride, which belongs to a drug group called 5alpha-reductase inhibitors lowers serum PSA and increases sensitivity of PSA to detect high-grade prostate cancer in men who had little or no symptoms of the lower urinary tract. We postulated that this effect would increase the accuracy and benefits of PSA-based prostate cancer screening. Finnish Randomized Study of Screening for Prostate Cancer was a large trial of over 80,000 men randomized either to be screened for prostate cancer with a PSA test at 4-year intervals or to be followed for prostate cancer incidence and mortality via national registries. Three consecutive screening rounds were commenced between 1996-2008. In the current study we compared the effects of PSA-based screening on prostate cancer risk and mortality separately among men who were using 5alpha-reductase inhibitors finasteride or dutasteride and among men who were not.

Author Interviews, Environmental Risks, Global Health, OBGYNE, Pediatrics / 18.02.2017

MedicalResearch.com Interview with: Chris Malley PhD The Stockholm Environment Institute University of York MedicalResearch.com: What is the background for this study? Response: When a baby is born preterm (at less than 37 weeks of gestation, an indicator of premature birth), there is an increased risk of infant death, or long-term physical and neurological disabilities. For example, 965,000 infant deaths in 2013 (35% of all neonatal deaths) have been estimated to be due to preterm birth complications. In 2010, an estimated 14.9 million births were preterm – about 4–5% of the total in some European countries, but up to 15–18% in some African and South Asian countries. The human and economic costs are enormous. There are many risk factors for preterm birth – from the mother’s age, to illness, to poverty and other social factors. Recent research has suggested that exposure to air pollution could also be a risk factor. Our study quantifies for the first time the global impact of pregnant women's exposure to outdoor fine particulate matter (PM2.5) by combining data about air pollution in different countries with knowledge about how exposure to different levels of air pollution is associated with preterm birth rates.

Abuse and Neglect, Author Interviews, Social Issues / 18.02.2017

MedicalResearch.com Interview with: Andrew Fenelon PhD Assistant Professor, Department of Health Services Administration University of Maryland School of Public Health. College Park, MD 20742 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the relatively large public investment in housing assistance at the federal level, there have been few nationwide analyses of the impacts of these programs on health and well-being. And as policymakers seek solutions to health disparities that incorporate some of the non-medical determinants of health (such as housing quality), our study can make an important contribution to both health and housing policy. We use an innovative data linkage program which links individuals in a federal household health survey and administrative housing records from the U.S. Department of Housing and Urban Development (HUD). We examine the health impacts of three HUD housing programs: public housing, housing choice vouchers, and multifamily housing. We find that public housing and multifamily housing lead to an improvement in self-reported health status, and public housing leads to a reduction in serious psychological distress. We do not find health impacts associated with housing choice vouchers. (more…)

MedicalResearch.com Interview with: Linard Filli, PhD Gait Research Lab Department of Neurology University Hospital Zurich Zürich MedicalResearch.com: What is the background for this study? Response: Gait dysfunction is common in patients with multiple sclerosis (MS) and is perceived as the most restricting of symptoms. Fampridine (4-aminopyridine, dalfampridine), a blocker of voltage-gated potassium channels, is currently the only approved medication for the symptomatic treatment of walking disorders in patients in both the early and late phases of  multiple sclerosis.

Author Interviews, Diabetes, OBGYNE / 18.02.2017

MedicalResearch.com Interview with: Dr Sophie Jacqueminet Praticien Hospitalier Service de Diabétologie Pole Cardio Métabolisme Hôpitaux Universitaires Pitié Salpêtrière - Charles Foix MedicalResearch.com: What is the background for this study? What are the main findings? Response: The proportion of women who are overweight or obese is increasing in almost all countries worldwide, and this is being accompanied by an increased risk of developing both type 2 diabetes (T2D) (whether pregnant or not) and gestational diabetes (GDM). While other studies have analysed the links between GDM and adverse outcomes in babies, very large studies that draw on an entire national database, study, are rare. In our research, all 796,346 deliveries taking place after 22 weeks in France in 2012 were included by extracting data from the hospital discharge database and the national health insurance system. Outcomes were analysed according to the type of diabetes and, in the GDM group, whether or not diabetes was insulin-treated. The cohort of 796,346 deliveries involved 57,629 (7.24%) mothers with gestational diabetes mellitus. Data linking the mother to the child were available for 705,198 deliveries (88% of the total). The risks of adverse outcomes were two to four times higher for babies of mothers with type 2 diabetes before pregnancy (pregestational diabetes) than for those with GDM. We then adjusted our data, limiting the analysis to deliveries after 28 weeks to ensure all women diagnosed with GDM were included (since diagnosis of GDM in most cases takes place at or after 28 weeks). Following adjustment, the increased risk of various complications for mothers with gestational diabetes versus mothers without GDM were: preterm birth 30%; Caesarean section 40%; pre-eclampsia/eclampsia 70%; babies born significantly larger than average size (macrosomia) 80%; respiratory distress 10%; birth trauma 30%; and cardiac malformations 30%. While these increased risks combine women with both insulin- and diet-treated GDM, most of the increased risk is found in women with insulin-treated GDM. This is because as stated above, the diabetes is more serious and blood sugar more difficult to control in women who need insulin treatment, resulting in a higher risk of complications than in those women treated with diet only.

Author Interviews, Biomarkers, Genetic Research, Personalized Medicine, Prostate Cancer / 17.02.2017

MedicalResearch.com Interview with: Dr. John L. Gore, MD Associate Professor Adjunct Associate Professor-Surgery Department of Urology University of Washington MedicalResearch.com: What is the background for this study? What are the main findings? Response: The rationale for our study derives from the uncertainty that both patients and clinicians confront when trying to make decisions about adjuvant therapy for prostate cancers found to have aggressive pathologic features at the time of radical prostatectomy. There is level 1 evidence in support of adjuvant radiation therapy in this setting, but several factors restrain providers from recommending adjuvant radiation. We found that interjecting a genomic test that predicts the risk of clinical metastases 5 years after surgery impacts the treatment recommended and helps men and clinicians feel more confident in the decision they are making or recommending.

Author Interviews, Cost of Health Care, Heart Disease, JAMA / 17.02.2017

MedicalResearch.com Interview with: James E. Udelson, MD Chief, Division of Cardiology Director, Nuclear Cardiology Laboratory Professor, Tufts University School of Medicine   MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are millions of stress tests done every year in the United States and many of them are normal,” said James Udelson, MD, Chief of the Division of Cardiology at Tufts Medical Center and the senior investigator on the study. “We thought that if we could predict the outcome of these tests by using information we already had from the patient before the test, we could potentially save the health care system money and save our patients time and worry.”   We were able to get a strong prediction of the possibility of having entirely normal testing and no clinical events such as a heart attack, by developing a risk prediction tool using ten clinical variables that are commonly available to a physician during an evaluation” (more…)
Author Interviews, Dermatology / 17.02.2017

MedicalResearch.com Interview with: Neelam A. Vashi, MD Assistant Professor of Dermatology Boston University Center of Ethnic Skin  and Mayra B. C Maymone, MD, DSc Doctor of Science, Dermatology Boston University School of Medicine Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Disorders of hyperpigmentation are common in clinical practice and frequently observed in dark-skinned individuals, a subset of the population that reportedly engages less with sunscreen use and other sun-protective behaviors. With the expected shift in US demographics to become a more racially and ethnically diverse population, there is growing interest in finding out more about the sun-protective habits in those with cutaneous hyperpigmentation. In this cross-sectional study, we found a surprisingly high rate of sunscreen use (67.5%). This is much higher than that observed in the general population and similar to rates observed in individuals with photosensitive disorders and skin cancer. However, the frequency of sunscreen reapplication and other sun-protective measures such as seeking shade and wearing hats were less commonly adopted in our study participants, emphasizing that even in a highly motivated population there is still room for improvement.

Author Interviews, NEJM, OBGYNE, Pediatrics / 17.02.2017

MedicalResearch.com Interview with: Carla M. Bann, Ph.D. Division of Statistical and Data Sciences RTI International Research Triangle Park, NC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Several medical advances have been made over the past two decades to improve the care and survival of infants born pre-term. However, approaches to care differ greatly among providers for infants born at the limits of viability (22 to 24 weeks gestation), far earlier than the 40 weeks generally expected for a pregnancy to reach full-term. Little is known about the outcomes of these infants, particularly whether those who survive experience significant neurodevelopmental impairments. RTI served as the data coordinating center for this research that examined the survival and neurodevelopmental impairment at 18-22 months corrected age of over 4,000 infants born at 22 to 24 weeks gestation during 2000 to 2011 at medical centers participating in a national research network funded by the NIH. In this group of babies, infant survival improved over time from survival rates of 30 percent in 2000-2003 to 36 percent in 2008-2011. The proportion of infants who survived without a neurodevelopmental impairment also increased from 16 percent in 2000-2003 to 20 percent in 2008-2011. (more…)
Author Interviews, Immunotherapy, Pulmonary Disease / 17.02.2017

MedicalResearch.com Interview with: Prof. Hossein-Ardeschir Ghofrani University of Giessen and Marburg Lung Center Giessen, Germany, and Member of the German Center of Lung Research and Department of Medicine Imperial College London London, UK MedicalResearch.com: What is the background for this study? Response: Pulmonary arterial hypertension (PAH) is characterised by increased pulmonary vascular resistance (increased resistance to blood flow in the pulmonary circulation), which can lead to right heart failure and death. Riociguat is the first of a new class of drugs – the soluble guanylate cyclase stimulators. It has been approved for the treatment of PAH based on the impressive efficacy and safety results from two pivotal Phase III studies: PATENT-1 and its long-term extension phase, PATENT-2. PATENT-1 was a 12-week, double-blind, randomized, placebo-controlled trial to evaluate the safety and efficacy of riociguat in patients with PAH. Patients who completed PATENT-1 without ongoing riociguat-related serious adverse events (AEs) could enter PATENT-2, in which they received open-label riociguat. PATENT-1 admitted patients whether they were treatment-naïve or already receiving targeted PAH therapies, such as endothelin receptor antagonists (ERAs) and prostanoids. This current analysis compared the safety and efficacy of riociguat between treatment-naïve and pretreated patients in the PATENT-2 long-term extension study. (more…)

MedicalResearch.com Interview with: Brian J. F. Wong, MD, PhD Division of Facial Plastic and Reconstructive Surgery Department of Otolaryngology–Head and Neck Surgery Beckman Laser Institute and Medical Clinic Department of Biomedical Engineering University of California, Irvine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Research in facial attractiveness is difficult because of the inherent subjectivity of rating. Most people can look at a face and instinctively tell you whether that face is attractive or not, by subconsciously picking up on biologic cues like fertility, coloration, and proportions. (more…)
Author Interviews, Biomarkers, Breast Cancer, Genetic Research / 17.02.2017

MedicalResearch.com Interview with: Carlos H. Barcenas M.D., M.Sc. Assistant Professor Department of Breast Medical Oncology MD Anderson Cancer Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the last decade we have realized that we were over-treating many early stage breast cancer patients. In addition to the chemotherapy’s obvious side effects, there are also long term complications for breast cancer survivors. Since 2005, we are using a 21-gene-expression assay that predicts the risk of distant recurrence among early stage breast cancer patients. In 2015, initial results from the international clinical trial, TAILORx, found that women with hormone receptor positive, HER2 and lymph node negative early stage disease that had a low recurrence score (RS) of 0-10 from this assay could have chemotherapy omitted altogether. While these findings changed care for women with a low RS, questions remain regarding the management of women with an intermediate RS, defined by this trial as a RS of 11-25. For our retrospective, single-institution study we identified 1,424 stage I and II breast cancer patients with hormone receptor positive, HER2 and lymph node negative treated between 2005 and 2011 who underwent the 21-gene expression assay. The RS distribution was: 297 (21 percent) scored 0–10; 894 (63 percent) scored 11-25; and 233 (16 percent) scored >25. Of those groups, 1.7, 15 and 73.4 percent received chemotherapy, respectively. With a median follow up of 58 months, those with a RS of 11-25 had an invasive disease-free survival (IDFS) rate at five years of 92.6 percent, regardless if patients received chemotherapy or not. Among those patients who did not receive chemotherapy, the estimated rates of IDFS and overall survival was 93 percent and 98 percent, respectively, which was comparable to those who did receive chemotherapy.

Alzheimer's - Dementia, Author Interviews / 17.02.2017

MedicalResearch.com Interview with: Shinsuke Ishigaki Department of Neurology Department of Therapeutics for Intractable Neurological Disorders Nagoya University Graduate School of Medicine Nagoya,Japan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Frontotemporal lobar degeneration (FTLD) is a pathological process that has been characterized by personality changes, abnormal behaviors, language impairment, and progressive dementia. The genetic and pathological similarities in fused in sarcoma (FUS), transactive response (TAR) DNA-binding protein 43 (TDP-43), and C9orf72 in relation to FTLD and amyotrophic lateral sclerosis (ALS) have recently lead to the recognition that the two conditions represent points on a spectrum of a single disease entity. Additionally, Frontotemporal lobar degeneration has also been classified as a tauopathy, characterized by an accumulation of phosphorylated microtubule-associated protein tau (tau) in affected neurons. Our study demonstrated a biological link between FUS/SFPQ and the regulation of tau isoforms involved in the early phase of Frontotemporal lobar degeneration. (more…)
Author Interviews, HIV, Immunotherapy / 17.02.2017

MedicalResearch.com Interview with: Brinda Emu MD Assistant Professor of Medicine (Infectious Diseases Yale University New Haven, CT  MedicalResearch.com: What is the background for this study? Response: Ibalizumab is a fully humanized monoclonal antibody that targets the CD4 receptor.  This Phase III registrational study enrolled individuals with HIV infection that harbor high levels of multi-drug resistance, with limited treatment options.  At IDWeek in October, 2016, data was presented that demonstrated patients experienced a significant decrease in viral load after receiving a single loading dose of ibalizumab 2,000 mg intravenously (IV) in addition to their failing antiretroviral therapies (ART) (or no therapy). Seven days after this loading dose, 83% of patients achieved a ≥ 0.5 log10 decrease from baseline compared with 3% during the seven-day control period .These results were statistically significant (p<0.0001). At CROI, additional data on the Week 24 results from this study are now presented. (more…)
Addiction, Author Interviews, Exercise - Fitness / 17.02.2017

MedicalResearch.com Interview with: Laurie de Grace Master's graduate from the Faculty of Physical Education and Recreation University of Alberta MedicalResearch.com: What is the background for this study? Response: Little is known about the development of substance addiction in the context of sport. There is substantial evidence showing a positive association between sport participation and alcohol use, particularly the binge drinking that is more commonly associated with athletes than non-athletes. However, the connection between sport participation and the use of other substances is not clear. We undertook this study to learn from the perspective of those in recovery from substance addiction, how sport may or may not have played a role in their substance use and subsequent addiction.

Author Interviews, Outcomes & Safety / 17.02.2017

MedicalResearch.com Interview wth: Kevin Kavanagh, MD, MS Board Chairman of Health Watch USA MedicalResearch.com: What is the background for this study? What are the main findings? Response: The genesis of our study was a desire to respond to a keynote speech at a major national patient safety conference which seemed to mitigate the problem of preventable hospital mortality in the United States. Our main finding is that there is credible evidence indicating that the preventable hospital mortality rate is more than 160,000 per year. When one considers the events which were not captured, and that we did not count diagnostic errors or post-discharge presentation of events, this number can be projected to approximate or exceed 200,000.

Author Interviews, Depression, JAMA, OBGYNE / 17.02.2017

MedicalResearch.com Interview with: Lisa Underwood, PhD Research Fellow| Centre for Longitudinal Research Growing Up in New Zealand | Who are Today’s Dads? School of Population Health, Faculty of Medical & Health Sciences University of Auckland  Auckland MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study is part of the contemporary, longitudinal study Growing Up in New Zealand, which is tracking the development of more than 6000 children born in 2009 and 2010. In previous reports we investigated antenatal and postnatal depression symptoms among the mothers of our cohort children. In this study we looked at the partners of those mothers to explore whether men and women have different risks for depression in each perinatal period. Our main findings were that expectant fathers were at risk if they felt stressed or were in poor health. Elevated depression symptoms following their child’s birth, were also linked to social and relationship problems. The strongest predictor of postnatal paternal depression was no longer being in a relationship with the child’s mother. (more…)
Author Interviews, Sexual Health, Technology / 16.02.2017

MedicalResearch.com Interview with: Dr. Krychman is Executive Director, President, and CEO of the Southern California Center for Sexual Health and Survivorship Medicine and Associate Clinical Professor at the University of California, Irvine, Department of Obstetrics and Gynecology. He is a Member of the International Society for the Study of Women’s Sexual Health (ISSWSH), The International Society for Sexual Medicine (ISSM) and a Certified Sexual Counselor by the American Association of Sexuality Educators, Counselors and Therapists (AASECT). He served as a member of the Standards Committee for the International Society for Sexual Medicine during their 2016 International Consensus Meeting.   MedicalResearch.com:  What is the background for this technology and study? What are the main findings? Response: Viveve Medical, Inc. is a women's health and wellness company committed to advancing new solutions to improve women's overall well-being and quality of life.  The internationally patented Viveve® technology and the GENEVEVE™ treatment, incorporates clinically-proven, cryogen-cooled monopolar radiofrequency (CMRF) energy to uniformly deliver non-ablative, deep penetrating volumetric heat into the submucosal layer of the vaginal introitus (opening) while gently cooling surface tissue to generate robust neocollagenesis.  One 30-minute in-office session tightens and restores the tissue around the vaginal introitus addressing the common medical condition of vaginal laxity and can improve a woman’s sexual function. VIVEVE I is a landmark study.  Results of the VIVEVE I clinical study, "Effect of Single-Treatment, Surface-Cooled Radiofrequency Therapy on Vaginal Laxity and Female Sexual Function: The VIVEVE I Randomized Controlled Trial," were recently published in the February 2017 issue of the Journal of Sexual Medicine (JSM) under the Female Sexual Function category.   Some of my high-level thoughts to reiterate from this study are: It is the first-ever large, randomized, sham-controlled study to demonstrate the safety and efficacy of energy-based procedures in gynecological applications, including vaginal laxity, which is a significant medical condition affecting millions of women worldwide that may lead to a reduction in sexual function. The primary endpoint of the VIVEVE I study was a comparison of the proportion of women reporting no vaginal laxity in the treatment group versus the sham group at 6 months post-treatment. Subjects receiving the active treatment were three times more likely to report no vaginal laxity at six months versus the sham group (p-value = 0.006). Statistically significant and sustained improvement in sexual function (baseline FSFI total score ≤26.5) after a single treatment, with an adjusted mean difference in the active group vs sham group of 3.2 at 6 months (p-value = 0.009). "Placebo Effect" in the sham group did not rise above dysfunctional (FSFI ≤26.5) and diminished at 6 months. Statistically significant improvement in sexual function was achieved in 93% of subjects in the active group vs the sham group in two individual key domains of FSFI (p-value = 0.007). Bottom line: Geneveve is a safe effective treatment that can be performed as an outpatient in one 30-minute visit to improve sexual function as it has been affected by vaginal laxity. (more…)

MedicalResearch.com Interview with: Corrine I. Voils, PhD Research Career Scientist, William S Middleton Veterans Memorial Hospital Visiting Professor of Surgery, University of Wisconsin-Madison MedicalResearch.com: What is the background for this study? What are the main findings? Response: Weight loss interventions can help people lose weight, but most people tend to regain weight after a weight loss period. There is a need to identify effective strategies to help people maintain weight loss. We found that an intervention focused on maintenance behavioral skills that was delivered primarily by telephone reduced weight regain compared to usual care over 56 weeks. (more…)
Author Interviews, CDC, NEJM, Zika / 16.02.2017

MedicalResearch.com Interview with: Gabriela Paz-Bailey MD PhD Senior Epidemiologist Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? Response: Zika virus is recognized as a cause of microcephaly and other severe birth defects when a woman is infected during pregnancy. Additionally, it has been associated with potentially fatal complications, such as Guillain-Barré syndrome. It is not well understood how often Zika virus particles can be detected in semen and other body fluids and for how long they remain detectable. Existing evidence is based on case reports and cross-sectional observations, primarily from returning travelers. A more comprehensive description of the dynamics of the early stages of Zika virus infection, observed within infected people over time, is needed to inform diagnostic testing as well as prevention recommendations and interventions.

Author Interviews, Breast Cancer, Cancer, Chemotherapy, Race/Ethnic Diversity / 16.02.2017

MedicalResearch.com Interview with:: Margaret Q. Rosenzweig PhD, CRNP-C, AOCNP, FAAN Acute and Tertiary Care Department University of Pittsburgh School of Nursing MedicalResearch.com: What is the background for this study? Response: A significant survival disparity still exists between African American and non-Hispanic white women diagnosed with breast cancer. There is evidence that symptom incidence, associated distress, and overall cancer-related distress may be unexplored, important contributing factors. The current study was a secondary, exploratory aim from the Attitudes, Communication, Treatment, and Support (ACTS) Intervention to Reduce Breast Cancer Treatment Disparity study, which is a randomized controlled trial of a psychoeducational intervention to encourage acceptance and adherence to chemotherapy compared with usual care for  African American women with breast cancer. The purpose of the current study was to: 1) describe and compare the number of chemotherapy-related symptoms and associated distress among AA women with breast cancer over the course of chemotherapy at 3 time points (at baseline before initiating chemotherapy, midpoint, and at the completion of chemotherapy); and 2) to describe the relationship between the number of chemotherapy-related symptoms and overall cancer distress compared with the ability to receive at least 85% of the prescribed chemotherapy within the prescribed timeframe.

MedicalResearch.com Interview with: Dr. med. Rachel Würstlein Senior Specialist Clinic and Polyclinic for Obstetrics and Gynecology Klinikum der Ludwig-Maximilians-Universität München • Campus Innenstadt Munich MedicalResearch.com: What is the background for this study? Response: Gene expression profiles provide important information on the risk of recurrence, and subtyping in HR+ HER2- early breast cancer, in addition to conventional clinicopathological factors. The PRIMe study was performed by the West German Study Group (WSG) and prospectively investigated the impact of the gene expression tests MammaPrint, a 70-Gene Breast Cancer Recurrence Assay, and the corresponding 80-Gene Molecular Subtyping Assay, BluePrint, on adjuvant chemotherapy decisions for early-stage breast cancer patients. To do this, a risk assessment (chemotherapy followed by endocrine therapy, versus endocrine therapy alone) for distant metastasis was performed in 452 patients from 27 study centers using conventional clinicopathological factors such as tumour size and grade first, then compared to the results of the gene expression tests MammaPrint and BluePrint. Doctors and patients then reviewed the results and made a decision on the optimal treatment plan, namely in deciding whether or not patients would benefit from, and should therefore be treated with adjuvant chemotherapy.

Allergies, Author Interviews, Immunotherapy, Imperial College, JAMA / 16.02.2017

MedicalResearch.com Interview with: Stephen R. Durham, MD Imperial College, London, and Royal Brompton and Harefield Hospitals NHS Foundation Trust London, United Kingdom MedicalResearch.com: What is the background for this study? What are the main findings? Response: Allergic rhinitis affects 1 in 4 the UK population and may compromise sleep and work/school performance and be associated with bronchial asthma. When nasal steroids and antihistamines do not work or cause side effects, allergen immunotherapy is an alternative. Immunotherapy using high doses of grass pollen allergen as monthly injections or daily tablets under the tongue are highly effective.
