Author Interviews, End of Life Care, JAMA / 03.10.2016

MedicalResearch.com Interview with: Joshua R. Lakin, MD Assistant Professor of Medicine Harvard Medical School Dana Farber Cancer Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: Research has increasingly shown the benefits of early palliative care interventions, especially in those around communication about patient goals and preferences in serious illness. These benefits include improved quality of life and psychological outcomes for patients as well as eased bereavement and decision making for loved ones. We have a large gap to fill in initiating early goals and values conversations with our patients and there are a myriad of systems failures and clinician barriers that do not allow us to do this work in a timely and effective way. Doing so with limited resources, both in specialty palliative care and in the many frontline clinicians doing this work, requires targeting our resources carefully. Doing these conversations earlier means identifying patients upstream, before they are in the last days of life. The Surprise Question – “Would you be surprised if this patient died in the next year?” – has emerged as an attractive option for screening for early palliative care interventions. It has been studied primarily in dialysis and cancer patients and has been demonstrated to have a strong association with risk of death. We set out to test it in a more diverse primary care population. (more…)

MedicalResearch.com Interview with: Jonas Esche Dipl.-Mol. Biomed University of Bonn Institute of Nutritional and Food Sciences DONALD Study MedicalResearch.com: What is the background for this study? Response: Modern western diets increase diet-dependent acid load and net acid excretion which are suggested to have adverse long-term effects on bone. Urinary potential renal acid load (uPRAL) is an established parameter to assess nutritional acid load. Urinary citrate, on the other hand, integrates nutritional and also systemic influences on acid-base homeostasis with high citrate indicating prevailing alkalization. Against this background urinary citrate excretion was used as a new index of acid-base status and its relationship with bone strength and long-term fracture risk was examined. (more…)

MedicalResearch.com Interview with: Elizabeth Franzmann, M.D. Scientific Founder and Chief Scientific Officer Vigilant Biosciences MedicalResearch.com: What is the background for this study? Response: Head and neck cancer involves cancers of the oral cavity, oropharynx and larynx. It is difficult to treat. Part of the challenge is that it is distinguishing the patients with tumors that are going to behave aggressively from those with less aggressive disease. As a result, many patients undergo treatment that may be more intensive and morbid than they need while others need more aggressive treatment. Tissue markers associated with prognosis may be able to help clinicians differentiate patients who need more aggressive treatment from those whose treatment can be less intensive. CD44 is a cell surface glycoprotein and tumor-initiating marker. CD44 and another surface protein, EGFR, are involved in tumor extension and are associated with poor prognosis. Certain forms of Human Papillomavirus (HPV) are known to cause oropharyngeal cancer and are associated with a good prognosis. P16 is a surrogate marker for the kind of HPV that causes cancer. Understanding the relationships between how these markers are expressed in cancer tissue may direct patient treatment in the future. (more…)

MedicalResearch.com Interview with: Dr. James McKinney MD MSc FRCP(C) Division of Cardiology University of British Columbia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sudden cardiac death (SCD) is the leading medical cause of death in young athletes. Sporting activity may predispose athletes with underlying cardiovascular conditions to develop life threatening ventricular arrhythmias during physical exercise. Despite being a relatively rare event, the death of a young healthy person is a tragic event that is difficult to comprehend. The prevalence of an underlying cardiovascular disorder in young athletes that predisposes to SCD is approximately 0.3%. Sudden cardiac death is often the first clinical manifestation of an underlying cardiovascular condition; up to 80% of athletes are previously asymptomatic. Pre-participation screening is the systematic practice of medically evaluating athletes for the purpose of identifying (or raising suspicion of) abnormalities that could provoke sudden death. There is agreement amongst sporting and medical bodies that athletes should undergo some form of pre-participation screening. An Achilles’ heel of screening is the significant number of false-positive screens that require subsequent costly secondary testing to rule out disease. Prevention of sudden cardiac death among athletes is a common goal, however the optimal strategy for its achievement is uncertain. (more…)
Author Interviews, Health Care Systems, Lancet, Mayo Clinic / 03.10.2016

MedicalResearch.com Interview with: Colin P. West, MD, PhD, FACP Divisions of General Internal Medicine and Biomedical Statistics and Informatics Departments of Internal Medicine and Health Sciences Research Mayo Clinic MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Physician burnout has reached epidemic levels, as documented in national studies of both physicians in training and practicing physicians demonstrating burnout rates in excess of 50%. Consequences include negative effects on patient care, professionalism, physicians’ own care and safety, and the viability of health-care systems. We conducted a systematic review and meta-analysis to better understand the quality and outcomes of the literature on approaches to prevent and reduce burnout. We identified 2617 articles, of which 15 randomized trials including 716 physicians and 37 cohort studies including 2914 physicians met inclusion criteria. Across interventions, overall burnout rates decreased from 54% to 44%, emotional exhaustion score decreased from 23.82 points to 21.17 points, and depersonalization score decreased from 9.05 to 8.41. High emotional exhaustion rates decreased from 38% to 24% and high depersonalization rates decreased from 38% to 34%. (more…)

MedicalResearch.com Interview with: Barak Ariel, PhD Jerry Lee Fellow in Experimental Criminology and Lecturer in Experimental Criminology University of Cambridge Alex Sutherland, D.Phil. RAND Europe MedicalResearch.com: What is the background for this study? Response: The very first randomised-controlled experiment on cameras in Rialto (California) was originally intended to ‘cut red tape’, but Rialto Police Department decided instead to look at whether wearing the cameras could help reduce complaints and police use-of-force. That study found that cameras did cut use-of-force and complaints, with the latter almost to zero in the 12 months of the experiment. Given that each complaint costs, millions of dollars in the US, there was a lot of interest following that study, and that research was seen as crucial in the widespread adoption of Body-Worn Cameras in the US and other countries. Although Rialto is typical of a lot of mid-sized police forces in the US, it is just one location at one time – so the roll out that was taking place had a very weak evidence base. The same results might not be found in other locations and given that many police forces started to roll out cameras without evidence, there was a strong justification for replicating the study. This paper (and two others already published) report results from x10 RCTs that took place in the UK and US, with more than 2 million residents, over a period of a year. (more…)

MedicalResearch.com Interview with: Silvia S. Martins, MD, PHD Associate Professor of Epidemiology Department of Epidemiology Mailman School Of Public Health Columbia University New York, NY 10032 MedicalResearch.com: What is the background for this study? Response: Given the high probability of nonmedical use among adolescents and young adults, the potential development of prescription opioid use disorder secondary to nonmedical use among youth represents an important and growing public health concern. Still, no study had investigated time trends, specifically if prescription opioid use disorder has increased in the past decade among adolescents, emerging adults and young adults who are nonmedical users of prescription opioids.

MedicalResearch.com Interview with: Eric Jacobs, PHD Strategic Director, Pharmacoepidemiology American Cancer Society, Inc. 250 Williams St. Atlanta, GA 30303 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Vasectomy is a common, inexpensive, and very effective method of long-term birth control. However, in 2014, an analysis from a large epidemiologic cohort study, the Health Professionals Follow-Up Study, found that vasectomy was associated with about 10% higher overall risk of prostate cancer and about 20% higher risk of fatal prostate cancer. Together with other researchers at the American Cancer Society, I analyzed the association between vasectomy and fatal prostate cancer among more than 363,000 men in the Cancer Prevention Study II (CPS-II) cohort, age 40 and older, who were followed for up to 30 years. This is the largest prospective analysis of vasectomy and fatal prostate cancer to date. We also examined vasectomy and prostate cancer in a subset of about 66,000 CPS-II study participants who were followed for new diagnoses of prostate cancer. We found no link between having had a vasectomy and risk of either developing or dying from prostate cancer. (more…)
Author Interviews, Brain Cancer - Brain Tumors, Radiation Therapy, Yale / 30.09.2016

MedicalResearch.com Interview with: Nataniel Lester-Coll, MD Chief Resident in Radiation Oncology at Yale New Haven, Connecticut  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recurrent Glioblastoma Multiforme (GBM) has limited treatment options and the prognosis is poor. Mibefradil diydrochloride was identified using a high-throughput compound screen for DNA double stranded break repair inhibitors. Mibefradil was found to radiosensitize GBM tumor cells in vitro and in vivo. Based on these findings, we sought to determine the maximum tolerated dose of mibefradil and radiation therapy in a Phase I recurrent GBM study. Eligible patients with recurrent  Glioblastoma Multiforme received Mibefradil over a 17 day period, with hypofractionated radiation (600 cGy x 5 fractions). There are 18 patients currently enrolled who have completed treatment. Thus far, there is no clear evidence of radionecrosis. A final dose level of 200 mg/day was reached as the maximum tolerated dose. The drug was very well tolerated at this dose. We saw intriguing evidence of enhanced local control in selected cases. Patients enrolled in a translational substudy who received Mibefradil prior to surgery were found to have adequate levels of Mibefradil in resected brain tumor tissue. (more…)

MedicalResearch.com Interview with: Paola Scaffidi, PhD Group Leader Cancer Epigenetics Laboratory The Francis Crick Institute London MedicalResearch.com: What is the background for this study? What are the main findings? Response: Every cancer is different, but even within the same tumor cells are highly diverse, and only some of them are truly immortal and drive tumor growth. This is quite surprising if we think that cancer arises from one cell that keeps replicating itself. So why are some cancer cells more dangerous than others? And why do some cells "get tired" along the way and, at some point, stop dividing? In our study we describe one cellular mechanism that provides some answers to these questions. We have found that to be able to divide indefinitely, cancer cells have to strongly reduce the levels of a nuclear protein called histone H1.0. This is needed to allow activation of many genes important for cancer cell proliferation, which otherwise would be somehow "hidden" within the cell nucleus. Importantly, though, while tumors grow, some cells raise back the levels of H1.0, which hides these genes again and makes the cells stop proliferating. So the end result is that within the same tumor we have a mix of cells, some which keep these important genes on, while others switch them off and, as a consequence, lose their ability to divide, and differentiate into a more mature state.

MedicalResearch.com Interview with: Melissa C. Bartick, M.D. Assistant Professor of Medicine Department of Medicine, Cambridge Health Alliance, Cambridge Harvard Medical School, Boston Massachusetts MedicalResearch.com: What is the background for this study? Response: There has never been a study that combined maternal and pediatric health outcomes and costs into a single model. My colleague Arnold Reinhold and I had published a pediatric study in 2010, which was widely publicized but needed to be updated. My colleagues and I published a maternal study in 2013. But the two studies had different methodologies, and so the total costs could not be simply added together. Here, we wanted to get a picture of the impact of breastfeeding in the US public health as whole, by creating a single model that combined maternal and pediatric outcomes. That had never been done before. (more…)

MedicalResearch.com Interview with: Dr Marjo Renko MD PEDEGO Research Unit University of Oulu Oulu, Finland MedicalResearch.com: What is the background for this study? What are the main findings? Response: For over a decade there has been suture materials containing antiseptic agent in the market. Trials in adults have shown some possible benefits from these sutures as in some studies they have reduced occurrence of surgical site infections. Only one small study had so far been published in children and thus we decided to carry out a large trial comparing sutures containing triclosan with ordinary ones. Our trial included over 1500 children who came to Oulu University Hospital for surgery. Surgical site infections were carefully monitored. Surgical site infections occurred in 2.6 % of the children who received absorbing sutures containing triclosan while that occurred in 5,4 % of the children who received ordinary sutures. (more…)

MedicalResearch.com Interview with: Adam Brufsky, MD, PhD, FACP Medical Director of the Women's Cancer Center University of Pittsburgh Medical Center MedicalResearch.com: What is the background for this study? What are the main findings?
  • The Make Your Dialogue Count survey was conducted by Harris Poll on behalf of Novartis between June 20 and August 22, 2014. A total of 359 surveys were collected among women 21 years+ living with advanced breast cancer in addition to 234 caregivers of women with advanced breast cancer and 252 licensed oncologists who treat at least five advanced breast cancer patients per month within the United States. Novartis conducted the survey with guidance from oncologists, patient advocacy experts and a psychologist to better understand the dialogue around treatment goals and decisions that takes place among advanced breast cancer patients, caregivers and oncologists.
  • Main survey findings show communication gaps exist in discussions between patients and oncologists, particularly around treatment plans and goals.
  • 89% of patients and 76% of oncologists said that it’s important or very important to discuss long-term treatment plans beyond the current recommended treatment at their initial advanced breast cancer diagnosis. Yet, 43% of patients reported that this did not take place.
  • 70% of patients and 65% of oncologists said that it’s important or very important to refer patients to support services at their initial advanced breast cancer diagnosis. Yet, only 36% of patients reported that this was something their doctor did.
  • 23% of oncologists said that at times their emotions have kept them from sharing certain information with their advanced breast cancer patients, and 27% of oncologists said that, in certain situations, they do not discuss with patients the fact that advanced breast cancer is incurable.

Author Interviews, BMC, Heart Disease, Mediterranean Diet, Nutrition / 30.09.2016

MedicalResearch.com Interview with: Dr Nita Forouhi, MRCP, PhD, FFPHM Programme Leader MRC Epidemiology Unit University of Cambridge School of Clinical Medicine Institute of Metabolic Science Cambridge Biomedical Campus MedicalResearch.com: What is the background for this study? What are the main findings? Response: The benefits of the Mediterranean diet for cardiovascular health are well documented in countries of the Mediterranean region and some other countries, but there is little such evidence in the UK general population. Our work fills this research gap. In our study we followed up 23,902 initially healthy Britons living in Norfolk (Eastern England) for an average of 12 to 17 years, and determined the occurrence of new cases of cardiovascular diseases (CVD) and deaths due to CVD during that time period. Our results showed that those adults who adhered to a Mediterranean diet had 6% to 16% lower risk of developing CVD, compared to those who had dietary habits further away from the Mediterranean-type diet pattern. This was the case even when we accounted for several important risk factors and correlates of CVD, including as age, sex, body mass index, lifestyle habits such as smoking, alcohol intake and physical activity, and socio-economic factors. We also modelled what would happen in the study population if all the participants increased their adherence to the Mediterranean-type diet. From this we estimated that nearly 4% of all new cardiovascular disease cases, or 12.5% of cardiovascular deaths in the population could potentially be avoided. This is novel information about the potential health benefit of a Mediterranean-type diet in a UK context. However, we should remember that our study was an observational study, not a clinical trial with a dietary intervention, and thus we cannot imply a cause and effect relationship between increasing adherence to the Mediterranean diet and reduction in cardiovascular disease. We defined the Mediterranean diet using a 15 point score based on guideline recommendations from a Mediterranean dietary pyramid published by the Mediterranean Diet Foundation. The recommendations had not previously been specifically tested for their associations with health, so our findings, for the first time, show the utility of the Mediterranean dietary pyramid. (more…)

MedicalResearch.com Interview with: Headshot portrait of Dr. Kim Harmon, family medicine, sports medicine.Kimberly G. Harmon, MD University of Washington Seattle, WA 98195. MedicalResearch.com: What is the background for this study? Response: Sudden cardiac death (SCD) in a young athlete is tragic devastating families and communities.  It has been characterized as “rare” by some, however, previous studies have looked at broad age ranges of athletes and used various methods to determine the incidence rate, sometimes only including athletes which have events during school sponsored events.  In addition, many studies only look at sudden cardiac death and do not include sudden cardiac arrest (SCA) where the athlete has a cardiac arrest but is resuscitated and survives. SCA is important to include as ideally we would like to prevent both SCA and SCD in athletes.  In this paper, over 1/3 of all US high school athletes were studied for six years to determine the incidence and the causes of SCA/D.   Media reports were used to identify cases and then autopsies were obtained in those who died.

MedicalResearch.com Interview with: Harvey Kaufman MD Quest Diagnostics Madison, New Jersey MedicalResearch.com: What is the background for this study? What are the main findings? Response: Quest Diagnostics is the leading provider of diagnostic information services, meaning we provide information and insights from our laboratory test services. This includes analyzing results of our laboratory test data in order to provide insights into health, wellness and disease to help providers, patients and health plans make better healthcare decisions. A Quest Diagnostics Health Trends™ study published in the Pediatrics evaluated 276,949 de-identified test results from children ages infant through 9 years over an 11-year period to determine trends in laboratory rotavirus detection and the impact of the rotavirus vaccine on rotavirus detection. Vaccination is recommended for infants. In the study, two patients groups were evaluated for rotavirus vaccine – likely vaccinated (children who were infants after vaccine availability) and unlikely vaccinated (children who were infants prior to vaccine availability).

MedicalResearch.com Interview with: Dr Sarah El-Heis MBBS, MRCP (London) Clinical Research Fellow MRC Lifecourse Epidemiology Unit University of Southampton Southampton General Hospital Southampton MedicalResearch.com: What is the background for this study? What are the main findings? Response: Atopic eczema is a common, multifactorial and potentially distressing skin condition. Evidence that it partly originates in utero is increasing with some studies suggesting links with aspects of maternal diet during pregnancy. Nicotinamide is a naturally occurring nutrient that is maintained through the dietary intakes of vitamin B3 and tryptophan. As a topical treatment it has been used in the management of some skin conditions including atopic eczema, and has been shown to have anti-inflammatory effects, to stabilise mast cells and to alter lipids in the outer layers of the skin. The objective of our study was to examine the link between maternal serum concentrations of nicotinamide and related tryptophan metabolites to the risk of atopic eczema in the offspring. We found that maternal late pregnancy concentrations of nicotinamide and related metabolite concentrations were not associated with offspring atopic eczema at age 6 months. Higher maternal serum concentrations of nicotinamide and anthranilic acid were, however, associated with a 30% lower risk of eczema at age 12 months. (more…)

MedicalResearch.com Interview with: Dr. Johan Frostegård MD PhD Professor of medicine Karolinska Institutet's Institute of Environmental Medicine and Consultant at Karolinska University Hospital's Emergency Clinic MedicalResearch.com: What is the background for this study? What are the main findings? Response: Statins are one of the worlds most sold medications, which has generated large profits, but also, in my opinion, helped many people. Still, side effects are much discussed after more than 2 decades of use, as exemplified by a current debate between Lancet and BMJ (the former has the opinion that side effects are not major issues, but the latter do not agree). Also the exact role of LDL (low density lipoprotein, also known as the ”bad cholesterol”) as a risk factor is discussed, and can vary, according to many researchers. LDL levels are important among middle aged persons, especially men, as a risk markers for cardiovascular disease, especially myocardial infarction. LDL is most likely less important as a risk factor in individuals above 60 years of age, and also among women – as compared to middle aged men. (more…)
Author Interviews, Brigham & Women's - Harvard, Depression, JCEM, Menopause, Sleep Disorders / 28.09.2016

MedicalResearch.com Interview with: Hadine Joffe, MD, MSc Associate Professor of Psychiatry, Harvard Medical School Vice Chair for Psychiatry Research Director of Division of Women's Mental Health / Dept of Psychiatry / Brigham and Women’s Hospital Director of Psycho-Oncology Research / Dept of Psychosocial Oncology and Palliative Care /Dana Farber Cancer Institute www.brighamwharp.org MedicalResearch.com: What is the background for this study? Response: We conducted this study to advance our understanding about causes of mood disturbance in the menopause transition that are specifically related to menopause. We used an experimental model to dissect out the contributions of hot flashes and sleep disturbance from contribution of changing levels of estrogen because hot flashes, sleep problems, and estrogen fluctuations co-occur and are difficult to distinguish from one another. Understanding whether hot flashes and/or sleep disturbance are causally related to mood disturbance will help us identify who is at risk for mood changes during the menopause transition. This is incredibly important now that we are finding effective non-hormonal treatments for hot flashes and sleep disruption. (more…)

MedicalResearch.com Interview with: Rosa & Co. LLC,Dr. Christina Friedrich Chief Engineer, PhysioPD Rosa & Co. LLC MedicalResearch.com: What is the background for this study? Response: Elan was developing compounds for the treatment of Parkinson’s Disease. The compounds were designed to modify negative effects of alpha-synuclein on neurotransmitter vesicle trafficking, but these effects are poorly understood. Elan and Rosa collaborated in the development of a Synuclein PhysioMap®, a graphical model architecture to support hypothesis generation and testing. The objectives of the project were to provide insight into alpha-synuclein function in vesicle trafficking, memorialize and communicate the current state of knowledge within Elan, and to recommend experiments to test hypotheses, resolve uncertainties and identify and prioritize potential targets.

MedicalResearch.com Interview with: Kenneth K. Mugwanya MBChB, MS Department of Epidemiology andDepartment of Global Health University of Washington, Seattle, Washington, USA Division of Disease Control, School of Public Health Makerere University Kampala, Uganda MedicalResearch.com: What is the background for this study? What are the main findings? Response: Women living in regions with high HIV prevalence are at high risk of HIV acquisition in pregnancy and postpartum because they infrequently use condoms, do not know their partner's HIV status, and have biologic changes or changes in their partner's sexual partnerships that increase susceptibility. Moreover, acute HIV infection during pregnancy or breastfeeding period is associated with high rates of mother-to child HIV transmission because of high circulating level of HIV virus in blood. Oral antiretroviral pre-exposure prophylaxis (PrEP) is a powerful HIV prevention strategy recommended by both the World Health organization and US Centers for Diseases Control and Prevention. PrEP is an attractive prevention strategy for women as it can be used discreetly and independent of sexual partners. However, there is limited research about the safety of PrEP in HIV-uninfected pregnant or breastfeeding mothers and their infants. (more…)

MedicalResearch.com Interview with: Prof Adrian S. Woolf Chair, Professor of Paediatric Science University of Manchester, UK MedicalResearch.com: What is the background for this study? Response: Several years ago, Laurent Fasano discovered that the Drosophila teashirt gene was needed to pattern the body of embryonic flies. He then found that this transcription factor had three similar genes in mammals. Working with Adrian Woolf in the UK, they found that Teashirt-3 (Tshz3) was needed in mice to make muscle form in the ureter When the gene was mutated, mice were born with ureters that were 'blown-up' and they failed to milk urine from the kidney with the bladder.

Author Interviews, C. difficile, Microbiome, Nature, Vanderbilt / 28.09.2016

MedicalResearch.com Interview with: Eric P Skaar, Ph.D., MPH Director, Division of Molecular Pathogenesis Ernest W. Goodpasture Professor of Pathology Vice Chair for Basic Research, Department of Pathology, Microbiology, and Immunology Vanderbilt University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nutrient metals are known to be a critical driver of the outcome of host-pathogen interactions, and C. difficile is the most common cause of hospital-acquired infections. C. difficile infection typically occurs following antibiotic-mediated disruption of the healthy microbiome. We were interested in learning how nutrient metals can shape the microbiome and impact the outcome of Clostridium difficile infection. We found that excess zinc alters the structure of the microbiome and increases the severity of C. difficile infection in mice. (more…)

MedicalResearch.com Interview with: Dr. Bashir A. Lwaleed PhD, FRCPath, PGCAP, FHEA, CBiol FSB, FIBMS Faculty of Health Sciences University of Southampton South Academic and Pathology Block (MP 11) Southampton General Hospital Southampton UK MedicalResearch.com: What is the background for this study? Response: The study merges two longstanding interests. We have long worked out of several departments at Southampton and Portsmouth on the therapeutic potential for natural products (including the medium – chain fatty acids GLA (evening primrose oil) and EPA (fish oil) as well as honeys from a number of floral sources. Secondly, there is an established research theme in the Faculty of Healthcare Science at Southampton addressing continence related issues; moreover catheter management as an economic and infection control issue is a major concern in the NHS Trust Urology department. Biofilms on catheters are sources of infection, honey has proven antibacterial (and other therapeutic) properties in topical applications such as skin ulceration. It is a logical step to assess whether a similar use may be made for honey instilled into the bladder and/or flushing the lumen of a catheter. (more…)
Author Interviews, JAMA / 28.09.2016

MedicalResearch.com Interview with: Kanu Okike MD MPH Department of Orthopaedic Surgery, Kaiser Moanalua Medical Center Honolulu, Hawaii MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many journals in the social sciences practice double-blind review, in which reviewers and authors are both blinded to each others' identities. In medicine, on the other hand, most journals practice single-blind review, in which authors' identities are known to reviewers. Concerns have been raised that this could lead to biased reviews, however, especially in the case of well-known authors. In our study, we composed a fabricated test manuscript and randomized reviewers for an orthopaedic journal to receive single-blind (prestigious authors listed) or double-blind (no authors listed) versions. In our study, the reviewers who were under the impression that the manuscript was written by prestigious authors (single-blind review) awarded higher marks and also recommended acceptance more often, in spite of the fact that the manuscripts were otherwise identical.

MedicalResearch.com Interview with: Iryna Saranchova MD PhD candidate Michael Smith Laboratories Vancouver, BC MedicalResearch.com: What is the background for this study? • The immune system is efficient at identifying and halting the tumour emergence at early stages. However, when metastatic (sufficient to cause death) tumour appears, the immune system is no longer able to recognize the cancer cells and control their growth and spread. • Recent studies of solid cancers have shown considerable heterogeneity between different tumour types and several lines of evidence suggest that tumours are not only heterogeneous, but they constantly evolve during the disease progression and this often hampers the existing treatment methods. • It means that it is important to consider each patient’s mutational changes accumulated over time in antecedent primary, metastatic lesions and/or local recurrences. This approach will help to understand the mechanism of tumour development, create a background for specific treatment modality and prevent therapeutic failure with consequent systemic relapse of the disease • Therefore, in our project we were aiming to find possible immune markers of tumour transition from the primary stage to its metastatic form. For this purpose, we selected a special study model: two pairs of separate mouse tumour cell lines, where metastatic cells arose from the initial primary tumour. (more…)
Author Interviews, Dental Research, Exercise - Fitness / 27.09.2016

MedicalResearch.com Interview with: Sonia Julià-Sánchez, PhD Universitat de Barcelona MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the last few years, a growing interest has focused on the potential correlation between the stomatognathic system and the body balance. While this relationship is still a subject for debate, it is well known that sensory information contributes differently on the postural control regulation depending on the conditions of the surface area. Therefore, we hypothesized that dental occlusion may contribute differently on the body balance control depending on the stability condition (stable versus unstable) and that influence might be more evident in fatigue conditions due to reorganization of the sensory information sources. In the current study we aimed to determine whether: (i) dental occlusion influences body balance in stable and unstable surfaces, and (ii) the influence of dental occlusion on the balance control comes strongly into effect under fatigue conditions. Our results showed that dental occlusion influenced balance control, at unstable level, both at rest and fatigue condition. However, when measuring at stable level, the influence of dental occlusion only reached significance in fatigue condition. (more…)

MedicalResearch.com Interview with: Dr. Michael Hill, MSc, MD, FRCPC Professor for the Departments of Clinical Neurosciences, Community Health Sciences, Medicine and Radiology University of Calgary Director of the Stroke Unit Calgary Stroke Program Alberta Health Services MedicalResearch.com: What is the background for this study? What are the main findings? Response: The HERMES collaboration is a pooled individual patient meta-analysis of recent endovascular ischemic stroke trials. The current analysis assesses the role of time to treatment and outcome. We show that there is a clear relationship between time from onset-to-treatment and outcome, with treatment gradually becoming less effective as time elapses from stroke onset. Treatment was still effect, on average, out to just beyond 7 hours from stroke onset. (more…)
