Author Interviews, JAMA, Opiods, Pain Research, Primary Care / 17.07.2017

MedicalResearch.com Interview with: Jane M. Liebschutz, MD, MPH Associate Professor of Medicine Section of General Internal Medicine Boston University School of Medicine Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: The number of patients receiving opioids for chronic pain has risen over the past 2 decades in the US, in parallel with an increase in opioid use disorder. The CDC and professional medical societies have created clinical guidelines to improve the safety of opioid prescribing, yet individual prescribers can find them onerous to implement. We developed an intervention to change clinical practice to support primary care physicians who prescribe the majority of opioids for chronic pain. The intervention included 4 elements- a nurse care manager to help assess, educate and monitor patients, an electronic registry to keep track of patient data and produce physician level reports, an individualized educational session for the physician by an opioid prescribing expert based on the physician-specific practice information and online resources to help with decision-making for opioid prescribing (www.mytopcare.org). We tested whether the intervention would improve adherence to guidelines, decrease opioid doses and decrease early refills, as a marker of potential prescription opioid misuse among 985 patients of 53 primary care clinicians in four primary care practices.

Addiction, Alcohol, Author Interviews, NIH / 17.07.2017

MedicalResearch.com Interview with: Lorenzo Leggio, M.D., Ph.D. Chief of the Section on Clinical Psychoneuroendocrinology and Neuropsychopharmacology, a NIAAA intramural laboratory MedicalResearch.com: What is the background for this study? MedicalResearch.com: What is the background for this study? What are the main findings? Response: Aldosterone is an important hormone involved in the control of blood pressure and electrolytes via its mineralcorticoid receptor (MR). In addition to its roles in the periphery in our body, aldosterone also acts on the brain where the MR is particularly present in regions like the amygdala. The amygdala plays an important role in stress, anxiety and excessive alcohol drinking. Back in 2008, we conducted a small pilot study where we found that alcohol-dependent patients with higher blood aldosterone concentrations have higher alcohol craving. (more…)
AHA Journals, Author Interviews, Stroke, Weight Research / 17.07.2017

MedicalResearch.com Interview with: Hugo J. Aparicio, MD, MPH Assistant Professor Vascular Neurology, Department of Neurology Investigator, The Framingham Heart Study www.framinghamheartstudy.org Boston University School of Medicine Boston, MA 02118-2526 MedicalResearch.com: What is the background for this study? Response: The association of body weight with survival after stroke has been studied before and is a controversial topic. Results have varied between studies and have often been contradictory. The observational findings that carrying extra weight can be protective after having a disease, like stroke or heart attack, has been called an obesity paradox, since obesity in itself is a risk factor for cardiovascular disease and mortality in the general population. Stroke research has focused on hospitalized stroke patients with weight measured at the time of the stroke. BMI is often missing in this group of patients, especially when a stroke is severe or the patients cannot report their weight. In the FHS we have data regarding weight prior to stroke, obtained during regularly scheduled research exams, with multiple data points on body weight and vascular risk factors over time. All before the stroke occurs. And have also compared survival outcomes with a group of control participants, those without stroke, to see if the so-called ‘obesity paradox’ is a non-specific finding seen in older adults or seen specifically in stroke patients.

Author Interviews, CDC, OBGYNE, Pediatrics, Race/Ethnic Diversity / 17.07.2017

MedicalResearch.com Interview with: Dr. Erica H. Anstey PhD Division of Nutrition, Physical Activity and Obesity National Center for Chronic Disease Prevention and Health Promotion Immunization Services Division National Center for Immunization and Respiratory Diseases CDC MedicalResearch.com: What is the background for this study? Response: The American Academy of Pediatrics (AAP) recommends that infants are breastfed exclusively for about the first 6 months and that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire. Although breastfeeding initiation and duration rates have increased overall in the United States, breastfeeding rates vary by geographic location, socioeconomic, and race/ethnic groups. Breastfeeding initiation and duration have been historically and consistently lower among black infants compared with white and Hispanic infants. There are many factors that influence a woman’s decision to start and continue breastfeeding. These include knowledge about breastfeeding, cultural and social norms, family and social support, and work and childcare environments. Some barriers to breastfeeding are disproportionately experienced by black women, including earlier return to work, inadequate receipt of breastfeeding information from providers, and lack of access to professional breastfeeding support.

Artificial Sweeteners, Author Interviews, CMAJ, Heart Disease, Weight Research / 17.07.2017

MedicalResearch.com Interview with: Meghan Azad PhD Assistant Professor, Department of Pediatrics & Child Health and Community Health Sciences, University of Manitoba; Associate Investigator, Canadian Healthy Infant Longitudinal Development (CHILD) Study Research Scientist, Children’s Hospital Research Institute of Manitoba; co-Lead, Population Health Pillar, Developmental Origins of Chronic Diseases in Children Network MedicalResearch.com: What is the background for this study? Response: Consumption of artificial sweeteners, such as aspartame, sucralose and stevia, is widespread and increasing.  Emerging data indicate that artificial, or non-nutritive, sweeteners may have negative effects on metabolism, gut bacteria and appetite, although the evidence is conflicting. MedicalResearch.com: What are the main findings? Response: We conducted a systematic review of 37 studies that collectively followed over 400,000 people for an average of 10 years. Only 7 of these studies were randomized clinical trials (the gold standard in clinical research), involving 1003 people followed for 6 months on average. The trials did not show a consistent effect of artificial sweeteners on weight loss, and the longer observational studies showed a link between consumption of artificial sweeteners and relatively higher risks of weight gain and obesity, high blood pressure, diabetes, heart disease and other health issues.

Author Interviews, Pediatrics, Primary Care, Vaccine Studies / 14.07.2017

  MedicalResearch.com Interview with: S. Hughes Melton, MD, MBA, FAAFP AAFP Foundation president MedicalResearch: What is the background for this initiative? What are the main vaccinations that teens should have?  Response: The Centers for Disease Control and Prevention (CDC) recommends adolescents receive four immunizations – two of which are administered as multi-dose series – to help protect against meningococcal meningitis caused by serogroups A, C, W and Y; human papillomavirus (HPV); tetanus, diphtheria and pertussis (Tdap); and influenza (flu).1 Despite these recommendations, millions of teens remain vulnerable to serious infectious disease.2,3 Family physicians are well equipped to immunize their patients against a host of common infectious diseases and improve public health. However, discussing teen vaccinations during annual appointments may present challenges due to other issues teens and their parents/guardians may be focused on at this age. The American Academy of Family Physicians Foundation (AAFP Foundation) launched Highlight on VACCINATIONS 4 TEENS to help remind family physicians and their care teams to make immunization a priority at these key appointments for teens.

Author Interviews, Dental Research, Microbiome, University of Pennsylvania / 14.07.2017

MedicalResearch.com Interview with: Dana T. Graves DDS Department of Periodontics School of Dental Medicine University of Pennsylvania Philadelphia, PA MedicalResearch.com: What is the background for this study? What are the main findings? Response: It was previously thought that diabetes did not have a significant effect on oral bacteria. We found that diabetes caused a change in the composition of the oral bacteria. This change caused resulted in a bacterial composition that was more pathogenic and stimulated more inflammation in the gums and greater loss of bone around the teeth. (more…)
Author Interviews, Dermatology, Immunotherapy, JAMA, Lung Cancer / 14.07.2017

MedicalResearch.com Interview with: Dr. Noelia Rivera MD Dermatologist Hospital Universitari Germans Trias i Pujol, Badalona Universitat Autònoma de Barcelona MedicalResearch.com: What is the background for this study? Response: In the last few years some new therapies targeting immune checkpoints have been developed. The programmed death receptor-1 (PD-1) are immune checkpoints that prevent the immune system to act against own tissues. By blocking these mediators it is possible to prevent tumors to escape from the immune system. About half of the patients receiving these therapies will develop mild to moderate cutaneous adverse events. In the pre-authorization studies for malignant melanoma these include rash, vitiligo, and pruritus. "Rash" has commonly been reported as an adverse event in many oncologic trials evaluating the drugs, without providing further information about the clinical or histological details. Lately, lichenoid eruptions associated to these therapies have been reported and it suggests that an important percentage of these reactions present lichenoid histological features. (more…)
Author Interviews, Technology / 14.07.2017

MedicalResearch.com Interview with: Dr Ian Williams PhD Associate Professor, DMT Lab Birmingham City University Faculty of Computing, Engineering and the Built Environment Centre for Digital Media Technology Millennium Point Birmingham UK MedicalResearch.com: What is the background for your work? Response: Our work at the DMT Lab (dmtlab.bcu.ac.uk) focuses on developing a novel Mixed Reality (MR) medical presentation platform which allows practitioners to interact with patient data and virtual anatomical models in real time. The system enables the presentation of medical data, models and procedures to patients with the aim of educating them on pending procedures or the effects of lifestyle choices (for example the effects of smoking or excessive alcohol consumption). The system employs an exocentric mixed reality environment which can be deployed in any room. It integrates a medical practitioner in real time with multimodal patient data and the corresponding result is a real time co-located visualisation of both the practitioner and the data, which they can interact with in real time.  We implement a natural interaction method into the system which improves a user’s level of direct interaction with the virtual models and provides a more realistic control of the data. The system can also be used in a fun educational setting where patients, students, children or any naive user, can learn about medical anatomical information via a real-time interactive mixed reality “body scanner”. This fun system overlays the MR information onto their own body in real-time and shows them scaled and interactive virtual organs, anatomy and corresponding medical information. We are aiming for this system to be used not only in patient education but also in engaging and informing people on lifestyle choices. (more…)
Author Interviews / 14.07.2017

MedicalResearch.com Interview with: Matthew R. McGrail, PhD Monash University School of Rural Health Churchill, Victoria Australia MedicalResearch.com: What is the background for this study? Response: Rural populations continue to experience relative shortages of the supply of primary care physicians, with associated links to poorer health. Although considerable research has identified factors that facilitate or impede supply of physicians in rural areas, macro-level empirical evidence of observed rural mobility of physicians - notably, which are more likely to move and why - is limited. Improved understanding of mobility and nonretention of rural physicians is important because of its impact on training and workforce policy, and resultant physician supply to both the origin area (ie, the location from which the physician moved) and to the destination area (ie, the location to which the physician has moved). The cost of mobility and staff turnover can be large, both in direct costs but also in terms of service quality and continuity to the community. In our study, we aimed to describe the geographic mobility patterns of rural primary care physicians. This evidence will provide stronger understanding of the factors behind the observed mobility and nonretention of rural primary care physicians. (more…)
Author Interviews, Autism, Gastrointestinal Disease, Nutrition / 14.07.2017

MedicalResearch.com Interview with: Bradley James Ferguson, PhD University of Missouri School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many individuals with autism spectrum disorder (ASD) have gastrointestinal problems, such as constipation, irritable bowel syndrome and abdominal pain, but the cause of these GI issues is not currently known. Previous research from our laboratory showed a significant positive relationship between cortisol levels and GI problems, especially for constipation. However, it is possible that other factors such as diet may affect GI functioning, especially since many children have altered diets. This study examined 32 different nutrients in the children’s diets, as assessed by a food frequency questionnaire that assessed the participant’s diet over the past month, and how each nutrient was related to upper and lower GI tract symptom scores over the past month created from the Questionnaire on Pediatric Gastrointestinal Symptoms – Rome III. The results showed no significant relationships between any of the nutrients and GI symptoms, suggesting that diet was not associated with GI symptoms in this sample. (more…)
Author Interviews, Dermatology, Melanoma / 14.07.2017

MedicalResearch.com Interview with: Maryam M. Asgari, MD, MPH Department of Dermatology Massachusetts General Hospital, Department of Population Medicine Harvard Medical School, Boston, Massachusetts Division of Research, Kaiser Permanente Northern California, Oakland  MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Laboratory studies show lithium, an activator of  the Wnt/ß-catenin signaling pathway, slows melanoma progression, but no published epidemiologic studies have explored this association. We conducted a retrospective cohort study of adult white Kaiser Permanente Northern California members (n=2,213,848) from 1997-2012 to examine the association between lithium use and melanoma risk. Our main finding is that lithium-exposed individuals had a reduced incidence of melanoma, did not develop very thick tumors (> 4 mm Breslow depth) or extensive disease at presentation, and had decreased melanoma-specific mortality compared to unexposed individuals suggesting a possible role for lithium in altering melanoma risk.

Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology, HIV, JAMA, Kaiser Permanente, Merck / 13.07.2017

MedicalResearch.com Interview with: Maryam M. Asgari, MD, MPH Department of Dermatology Massachusetts General Hospital, Department of Population Medicine Harvard Medical School, Boston, Massachusetts Division of Research, Kaiser Permanente Northern California, Oakland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nonmelanoma skin cancer – defined as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) – is a common malignant condition, affecting more than 2 million Americans every year. BCCs are more common than SCCs among individuals with healthy immune systems, while SCCs are more predominate than BCCs among people who are immunocompromised. We examined how laboratory markers used to evaluate HIV disease progression may be associated with subsequent nonmelanoma skin cancer risk in white patients previously diagnosed with at least one such cancer from 1996 to 2008.  We measured CD4 count, viral load and subsequent nonmelanoma skin cancer. The study included 455 participants with HIV and 1,952 without HIV. All were members of the Kaiser Permanente Northern California health care plan. (more…)

Author Interviews, Colon Cancer / 13.07.2017

MedicalResearch.com Interview with: Dr.Yi Xu PhD Center for Infectious and Inflammatory Diseases Institute of Biosciences and Technology Department of Microbiology and Microbial Genetics, University of Texas Health Science Center Texas A&M Health Science Center College Station, Texas MedicalResearch.com: What is the background for this study? Response: Colorectal cancer is fairly treatable when caught early with regular screenings, but it is still the second-leading cause of cancer-related deaths in American men and the third-leading cause in women. Researchers at Texas A&M have found that a subspecies of the bacterium Streptococcus gallolyticus appears to actively promote the development of colorectal cancer, which could lead to potential treatment strategies. Their findings are published in the journal PLOS Pathogens. Scientists have known for some time that people infected with S. gallolyticus are more likely to have colorectal cancer. “This association was well established in the clinical literature,” said Yi Xu, PhD, associate professor at the Texas A&M Institute of Biosciences and Technology and principal investigator of the study. However, it was unclear if that relationship was cause or effect—that the bacteria promote cancer development—or if S. gallolyticus simply grows easily in the environment that the tumor cells provide.  (more…)
Author Interviews, Environmental Risks, Weight Research / 13.07.2017

MedicalResearch.com Interview with: Heather M. Stapleton PhD Dan and Bunny Gabel Associate Professor of Environmental Ethics and Sustainable Environmental Management EEH Program Chair Nicholas School of the Environment Duke University Durham, North Carolina 27708 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Building materials and products common to most homes (e.g. furniture, TVs, carpets, etc) are often treated with synthetic chemicals, which migrate out of the products over time and accumulate in house dust, where residents can be exposed to these chemicals on a daily basis. This study assessed approximately forty chemicals commonly detected and measured in house dust samples for their ability to stimulate the development of fat cells, using a mouse precursor fat cell model. Approximately two thirds of these chemicals were able to promote lipid accumulation by these cells and/or stimulate the proliferation of the precursor fat cells. We then assessed eleven extracts of indoor house dust samples (containing mixtures of these chemicals) and exposed our cells to these extracts, finding that even low levels of these extracts were sufficient to promote the accumulation of lipids and/or the proliferation of the fat precursor cells.

Author Interviews, Brigham & Women's - Harvard, Lifestyle & Health, NEJM, Nutrition / 13.07.2017

MedicalResearch.com Interview with: Mercedes Sotos Prieto PhD Research Fellow Department of Nutrition Harvard T. H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous research have found that adherence to the 2010 Alternate Heathy Eating Index, the Mediterranean Diet pattern, and DASH pattern is associated with health benefits, but none of those studies have examined dynamic changes in diet quality over time and subsequent risk of mortality. This is the first study to demonstrate that improvement in these three diet scores over time is associated with reduced risk of total and cardiovascular mortality. In contrast, worsening diet quality over 12-years was associated with 6%-12% increased mortality. In addition, not only improvement in diet quality but maintaining a high adherence to any of the three dietary patterns over 12 years was significantly associated with 9%-14% lower total mortality.

Author Interviews, NEJM, Prostate Cancer / 13.07.2017

MedicalResearch.com Interview with: Dr. Timothy Wilt, MD MPH Core Investigator: Minneapolis VA Center for Chronic Disease Outcomes Research Staff Physician: Section of General Internal Medicine, Minneapolis VA Health Care System Professor: Medicine, University of Minnesota School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prostate cancer is common and potentially serious. However, the comparative benefits and harms of surgery versus observation in men with localized prostate cancer are not known. After nearly 20 years, surgery did not significantly reduce all-cause or prostate cancer mortality compared to observation, particularly in men with low risk disease. Surgery was associated with more harms than observation, causing complications within 30 days in about 20% of men and large long term increases in urinary incontinence, sexual dysfunction and dissatisfaction, as well as treatment related bother and reductions in daily functioning.

Author Interviews, Depression, Gender Differences, Pediatrics / 12.07.2017

MedicalResearch.com Interview with: Jie-Yu Chuang PhD Department of Psychiatry University of Cambridge Cambridge, United Kingdom  MedicalResearch.com: What is the background for this study? Response: Men and women appear to suffer from depression differently, and this is particularly striking in adolescents. By 15 years of age, girls are twice as likely to suffer from depression as boys. There are various possible reasons for this, including body image issues, hormonal fluctuations and genetic factors, where girls are more at risk of inheriting depression. However, differences between the sexes don't just involve the risk of experiencing depression. Men are more liable to suffer from persistent depression, whereas in women depression tends to be more episodic. Compared with women, depressed men are also more likely to suffer serious consequences from their depression, such as substance abuse and suicide. Despite this, so far, most researchers have focused on depression in women, likely because it is more common. As a result, we'd like to make people more aware of the sex difference issue in depression. (more…)
Author Interviews, JAMA, Outcomes & Safety / 12.07.2017

MedicalResearch.com Interview with: Riyaz Bashir MD, FACC, RVT Professor of Medicine Director, Vascular and Endovascular Medicine Department of Medicine Division of Cardiovascular Diseases Temple University Hospital Philadelphia, PA 19140 MedicalResearch.com: What is the background for this study? Response: The use of inferior vena cava filters (IVCF) has been increasing in the United States (US) despite uncertainty about the effectiveness of IVCFs in reducing venous thromboembolism (VTE)-associated morbidity and mortality.  Prompted by the report of high prevalence of fracture and embolization of Bard IVCFs, the US Food and Drug Administration (FDA) issued a device safety warning on August 9th 2010. In this study, we evaluated national trends of IVCF placement in the US between 2005 and 2014 using the National Inpatient Sample database.  The authors found that there was a 29% reduction in filter use following the 2010 FDA advisory, even though the rates of VTE-related hospitalizations remained unchanged.

Author Interviews, Cost of Health Care, Heart Disease, JAMA / 11.07.2017

MedicalResearch.com Interview with: Sacha Bhatia, MD, MBA, FRCPC Scientist, Women's College Research Institute Director, Women’s College Hospital Institute for Health System Solutions and Virtual Care Cardiologist, Women's College Hospital and University Health Network Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: The USPSTF recommends against screening with resting electrocardiography (ECG) for the prediction of coronary heart disease (CHD) events in asymptomatic adults at low risk for CHD events. We conducted a retrospective cohort study of the frequency of resting ECGs in low risk patients within 30 days of an annual health exam. We found that 21.5% of low risk patients in Ontario, Canada had a ECG, with significant variation among primary care physicians (1.8% to 76.1%). Moreover, low risk patients who had a ECG were five times more likely to receive another cardiac test or cardiology consultation than those that did not receive an ECG. At one year the rate of mortality, cardiac hospitalizations and revascularization was <0.5% in each group. (more…)
Author Interviews, Infections, Lancet, STD, Vaccine Studies / 11.07.2017

MedicalResearch.com Interview with: Helen Petousis-Harris. BSc, PhD Senior Lecturer, Dept General Practice and Primary Health Care Academic Head, Immunisation Research and Vaccinology Immunisation Advisory Centre School of Population Health, Faculty of Medical and Health Sciences University of Auckland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Early thinking came from two quarters. One, the observation that the NZ OMV vaccine appeared broadly protective – beyond the clone it was based on and two, the observation of graphs depicting annual number of cases from both Cuba and NZ. There is nothing to suggest other types of meningococcal vaccine have had any effect on gonorrhoea so we are interested in the OMV vaccines. This led to the hypothesis that as these two Neisseria species are related the meningococcal OMV in the form of a vaccine may offer some kind of cross protection. To explore this possibility we conducted a case-control study that compared the vaccination status of cases (gonorrhoea) and controls (Clamydia). We found that the cases with gonorrhoea were less likely to be vaccinated than the controls and after we controlled for confounders – ethnicity, SE deprivation, age we found a vaccine effectiveness of 31%.

MedicalResearch.com Interview with: Mattias Lorentzon, PhD Professor, Senior Physician Head of Geriatric Medicine, Institute of Medicine, Sahlgrenska Academy Sahlgrenska University Hospital, Mölndal Mölndal, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: It was previously known that alendronate reduces the risk of vertebral fractures in patients using oral glucocorticoids, but there were no studies regarding hip fractures, which are the most severe osteoporotic fractures, often resulting in disability and mortality. We found that older patients prescribed alendronate after starting medium to high doses of oral prednisolone had a much lower risk of hip fracture than patients not taking alendronate. (more…)

MedicalResearch.com Interview with: Dr. Jordi Bruix, MD Professor of Medicine University of Barcelona Director of the Barcelona Clinic Liver Cancer (BCLC) Group Liver Unit Hospital Clinic of Barcelona MedicalResearch.com: What is the background for this study? What are the main findings? Response: The RESORCE Phase III pivotal trial is an international, multicenter, placebo-controlled trial which investigated the efficacy of Stivarga (regorafenib) in adults with Child-Pugh A and Barcelona Clinic Liver Cancer Stage Category B or C hepatocellular carcinoma (HCC) who had documented disease progression following first-line treatment with Nexavar (sorafenib). Trial participants were administered a daily oral 160mg dose (three weeks on/ one week off) of regorafenib plus best supportive care (BSC), or placebo plus BSC. Results from the trial demonstrated that participants treated with regorafenib experienced a statistically significant and clinically meaningful improvement in the study’s primary endpoint—overall survival (OS). Participants treated with regorafenib demonstrated a median overall survival of 10.6 months vs. 7.8 months with placebo. At ASCO 2017, an exploratory analysis evaluated the impact of baseline alpha-fetoprotein (AFP) and c-Met as predictors of poor prognosis in patients enrolled in the RESORCE trial (Abstract #4078).

Author Interviews, BMC, Prostate Cancer, Race/Ethnic Diversity, Weight Research / 11.07.2017

MedicalResearch.com Interview with: Aurora Perez-Cornago, PhD Cancer Epidemiology Unit Nuffield Department of Population Health University of Oxford MedicalResearch.com: What is the background for this study? What are the main findings? Response: Greater height and adiposity have been suggested as possible prostate cancer risk factors, but these associations are not clear, probably because most previous studies have not looked separately at different tumour subtypes. For this reason, we wanted to look at these associations splitting tumours into subtypes according to tumour stage and histological grade, looking as well at death from prostate cancer. We found a marked difference in risks looking at low and high risk tumours. Taller men and men with greater adiposity had an elevated of high-grade prostate cancer and prostate cancer death. (more…)

MedicalResearch.com Interview with: Marc J. Gunter, PhD  From International Agency for Research on Cancer Lyon, France MedicalResearch.com: What is the background for this study? Response: U.S. and Japanese studies have previously found that drinking more coffee was related with a lower risk of death. However, in European populations, where coffee consumption and preparation methods are more varied, the relationship was less certain as relatively small studies had previously been conducted. Our analysis was undertaken in ~500,000 men and women from 10 European countries, the largest study to date investigating the coffee and mortality relationship. (more…)

Author Interviews, Biomarkers, Brain Injury / 10.07.2017

MedicalResearch.com Interview with: Dr Lisa J Hill PhD Institute of Inflammation and Ageing Research Fellow Neuroscience and Ophthalmology Institute of Inflammation and Ageing College of Medical and Dental Sciences University of Birmingham UK  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Traumatic brain injury (TBI) is the leading cause of death and disability among young adults and, according to the World Health Organization, by 2020 TBI will become the world’s leading cause of neurological disability across all age groups.  Early and correct diagnosis of traumatic brain injury is one of the most challenging aspects faced by clinicians. Being able to detect compounds in the blood that help to determine how severe the brain injury is would be of great benefit to patients and aid in their treatment.  Inflammatory markers are particularly suited for biomarker discovery as TBI leads to very early alterations in inflammatory proteins.  The discovery of reliable biomarkers for the management of TBI would improve clinical interventions. We collected blood samples from 30 injured patients within the first hour of injury prior to the patient arriving at hospital and analysed them. Analysis of protein biomarkers from blood taken within the first hour of injury has never been carried out until now. We used a panel of 92 inflammation-associated human proteins when analysing the blood samples. The analysis identified three inflammatory proteins, known as CST5, AXIN1 and TRAIL, as novel biomarkers of TBI. (more…)
