Author Interviews, JAMA, Ophthalmology, Zika / 15.11.2016

MedicalResearch.com Interview with: Camila Ventura MD Pediatric Retina Research Fellow at Bascom Palmer Eye Institute (BPEI), USA PhD student at Federal University of São Paulo (Unifesp) Medical Retina, Ocular Oncology, and Uveitis Department at Altino Ventura Foundation Brazil MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Brazilian outbreak of Zika virus (ZIKV) began in April 2015 and since then, we have not been able to stop its rapid spread throughout the Americas. Not only has ZIKV been disseminating very rapidly, patients affected by the ZIKV have also been presenting with some findings never before reported in the literature. Until recently, ZIKV infection was only associated with mild symptoms such as headache, rash, arthralgia, and conjunctivitis. However, in October 2015, a twenty-fold increase in the prevalence of newborns with microcephaly was reported that was later confirmed to be associated to ZIKV infection during pregnancy. Although microcephaly and other central nervous system findings were the first abnormalities reported, recent publications have described other malformations associated with ZIKV congenital infection including hearing loss, limb anomalies and ocular findings. Due to all of these systemic findings, this new clinical condition has been named Congenital Zika Syndrome (CZS). In January 2016, our group published the first report on the ocular findings of infants with microcephaly and presumed congenital ZIKV infection, followed by another manuscript describing 10 additional cases. We have also contributed with an article published in JAMA Ophthalmology reporting the risk factors associated to the ocular findings in babies with CZS. Other authors such as De Paula Freitas et al and Miranda 2nd et al, have also contributed to the literature by describing similar ocular findings in these infants with CZS. In the present case series, we describe the Ocular Coherence Tomography (OCT) findings in ten eyes of eight infants with CZS. (more…)

Accidents & Violence, Author Interviews, JAMA / 15.11.2016

MedicalResearch.com Interview with: Ted Alcorn, MHS, MA Everytown for Gun Safety Brooklyn, New York MedicalResearch.com: What is the background for this study? Response: Two decades ago, opponents of gun violence prevention recognized that they could curb the development and enactment of effective laws if they halted scientific research on which good policy would be grounded or justified. So they adopted a strategy of intimidation towards the leading federal agencies funding research on this topic and generating data on which analysis relied. Journalists that observed the pattern and scientists that lived through it often described the “chilling effect” this had on the field of gun violence prevention research. (more…)
Accidents & Violence, Author Interviews, JAMA, Pediatrics / 15.11.2016

MedicalResearch.com Interview with: Katherine P. Theall, PhD Associate Professor Global Community Health and Behavioral Services Tulane University School of Public Health and Tropical Medicine New Orleans, Louisiana MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are stark health disparities in the U.S. by socioeconomic position as well as between racial and ethnic groups. Many of these health disparities may have a root cause in childhood and be driven by social risk factors. The authors report each neighborhood stressor was associated with biological stress as measured by shortened telomere length and cortisol functioning. Many children are exposed to violence and a greater understanding of the effect on children’s health is critical because social environmental conditions likely contribute to health disparities. Socioeconomically disadvantaged communities have a higher exposure to violence. Limitations of the study include its lack of applicability to other demographic groups. The study also cannot establish causality. (more…)
Author Interviews, Emergency Care, Geriatrics, Infections / 15.11.2016

MedicalResearch.com Interview with: John P. Haran, MD Assistant Professor Department of Emergency Medicine University of Massachusetts Medical School UMass Memorial Medical Group Worcester, MA MedicalResearch.com: What is the background for this study? Response: In 2014, the Infectious Disease Society of America (IDSA) updated their guidelines for the management of skin and soft tissue infection in response to high MRSA infection rates as well as high treatment failure rates for skin and soft tissue infections. Greater than 1 in 5 patients treated for a skin abscess will fail initial treatment. Historically antibiotics have been shown to be unnecessary in the treatment of uncomplicated purulent infections. This notion has been recently challenges when authors published a randomized control trial using trimethoprim-sulfamethoxazone in the NEJM that demonstrated a minimal increase in cure rates for outpatient treatment of uncomplicated skin purulent skin infections. In this study they did not follow IDSA-guidelines nor model or stratify their analysis. It is possible their findings may be due to at-risk patient groups that did not receive antibiotics. Many widely used clinical decision rules incorporate age into their decision algorithms, however the IDSA did not do this with their recent guidelines. (more…)

MedicalResearch.com Interview with: Amitoj Singh MD Chief Cardiology Fellow St. Luke’s University Health Bethlehem, Pennsylvania MedicalResearch.com: What is the background for this study? Response: Marijuana use in steadily increasing and it is the most commonly used illicit drug in the US and worldwide. There has been a recent increase in reports of heart and vascular complications associated with its use. These include Myocardial infarctions, stroke and takotsubo. We had two questions that we wanted to answer with our study: a) Is there an association between marijuana use and development of Transient Regional Ventricular Ballooning [TVRB] (aka Stress Cardiomyopathy /Broken Heart Syndrome/ Takotsubo)? b) If the above is true, what are the differences between Marijuana users (MU) and Non Marijuana Users (NMU) who developed Stress Cardiomyopathy.

Author Interviews, Dermatology, Melanoma, Surgical Research / 14.11.2016

MedicalResearch.com Interview with: Timothy Patton, DO Department of Dermatology Falk Medical Center University of Pittsburgh Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: As dermatologists we are confronted daily with how to manage lesions that are biopsied and diagnosed as dysplastic nevi. These lesions are considered by some to be potential melanoma precursors and by others as benign lesions with little to no malignant potential. Often, particularly for lesions with severe atypia these lesions are re excised. There are no prospective studies or consistent guidelines as to how to manage these lesions. We decided to retrospectively look at the outcome of 451 patients with dysplastic nevi with severe atypia, many of whom had not had their lesions re-excised, who had at least 5 years of follow up to determine if any developed melanoma at the site of the biopsied dysplastic nevus or distantly. We found no cases of metastatic melanoma in patients who did not already have a diagnosis of melanoma. We found two cases of thin melanoma in patients who had their lesions re-excised. Both of those patients were treated with reexcision and did not develop subsequent melanoma metastasis or recurrence. (more…)

MedicalResearch.com Interview with: Kevin Fitzgerald, Ph.D. Alnylam Pharmaceuticals Cambridge, MA 02142 MedicalResearch.com: What is the background for this study? Response: Inclisiran (ALN-PCSsc) is a subcutaneously administered RNAi therapeutic targeting PCSK9 in development for the treatment of hypercholesterolemia. The Phase 1 trial of inclisiran was conducted in the U.K. as a randomized, single-blind, placebo controlled, single ascending-and multi-dose, subcutaneous dose-escalation study in 69 volunteer subjects with elevated baseline LDL-C (≥ 100 mg/dL). The primary objective of the study was to evaluate the safety, side effect profile, and pharmacodynamics effects of inclisiran. (more…)
Asthma, Author Interviews, Education, Pediatrics / 14.11.2016

MedicalResearch.com Interview with: Manoj Warrier, M.D. Allergy, Asthma & Sinus Care Center Adjunct Associate Professor of Pediatrics Saint Louis University and Cardinal Glennon Children's Medical Center St. Louis, MO 63127 MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2012, Missouri House Bill 1188 was passed, which allowed trained employees in Missouri schools to administer asthma related rescue medications at their discretion to students experiencing an asthma exacerbation, even if the individual student did not have their own supply of the medication. The Asthma and Allergy Foundation of America St. Louis Chapter (AAFA-STL) was instrumental in facilitating passage of this bill and also created the RESCUE (Resources for Every School Confronting Unexpected Emergencies) program, which provides equipment and access to free medications to treat acute asthma symptoms, mainly supporting schools with lower income populations. AAFA-STL tracked how often RESCUE supplies were used and found that equipment was used 1357 individual times in 2013-2014 school year, with students going back to class 86.07%, sent home 10.83%, and sent to emergency department (ED) only 1.33% of the time. In the 2014-2015, they found similar results with equipment used 1720 individual times, with students going back to class 84.48%, sent home 10.81%, and sent to ED 3.14% of the time. (more…)
Allergies, Asthma, Author Interviews, Flu - Influenza, Pediatrics, Vaccine Studies / 14.11.2016

MedicalResearch.com Interview with: Deepa Patadia, MD Wexner Medical Center The Ohio State University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Influenza vaccination is recommended every autumn for all children 6 months of age and older. It is particularly important for children with asthma, who are at high risk of hospitalization or severe illness if they contract influenza infection. The rates of influenza vaccination in children with asthma have not previously been well studied, but Healthy People 2020 has set a target goal to vaccinate 70% of all children for influenza. We found that rates of vaccination in our large primary care population was much lower than the target rate, with less than 50% of all children receiving the vaccine each year over a 5 year period; however rates were higher in children with asthma, albeit still only at 55%.

Author Interviews, Heart Disease, Pediatrics, University of Pennsylvania / 14.11.2016

MedicalResearch.com Interview with: Maryam Y. Naim, MD Pediatric Cardiac Intensive Care Physician The Cardiac Center The Children’s Hospital of Philadelphia Perelman School of Medicine The University of Pennsylvania, Philadelphia MedicalResearch.com: What is the background for this study?  Response: In adults bystander compression only CPR has similar outcomes to bystander conventional COR therefore the The American Heart Association recommends untrained lay rescuers perform compression only CPR in adults that have an out of hospital cardiac arrest. In children respiratory arrests are more common therefore conventional CPR with chest compressions and rescue breaths are recommended for out of hospital cardiac arrest. (more…)
Author Interviews, Blood Pressure - Hypertension, Heart Disease, JACC, Race/Ethnic Diversity, UT Southwestern / 13.11.2016

MedicalResearch.com Interview with: Wanpen Vongpatanasin, M.D. Professor of Medicine Norman & Audrey Kaplan Chair in Hypertension Fredric L. Coe Professorship in Nephrolithiasis and Mineral Metabolism Research Director, Hypertension Section, Cardiology Division, UT Southwestern Medical Center Dallas, TX 75390-8586 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Aortic stiffness is known to be associated with cardiovascular disease, including heart attack, stroke, and heart failure, possibly related to increase afterload to the left ventricle. Previous studies have not directly assessed proximal aortic function among ethnic minorities in the United States. We evaluated the multiethnic, population-based Dallas Heart Study participants (N=2544, 54.2% women, 49.7% Black) who underwent cardiovascular magnetic resonance imaging (CMR) at 1.5 Tesla. Aortic stiffness and characteristic impedance (Zc) were determined from aortic arch PWV and lumen area measurements. Linear regression was used to evaluate ethnic differences in proximal aortic wall stiffness using aortic arch PWV and Zc as dependent variables with and without adjustment for traditional cardiovascular risk factors.

Author Interviews, Brigham & Women's - Harvard, Gender Differences, Memory, Menopause / 12.11.2016

MedicalResearch.com Interview with: Jill M. Goldstein, Ph.D. Director of Research for the Connors Center for Women's Health and Gender Biology Brigham and Women's Hospital and Professor of Psychiatry and Medicine at Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Maintaining intact memory function as we age is one of the primary public health challenges of our time. In fact, women are at almost twice the risk for Alzheimer's disease and it is not only because women live longer. Thus, it is incumbent upon us to understand this sex difference and incorporate the knowledge into the development of sex-dependent therapeutics. Our study focused on beginning this investigation by understanding how memory circuitry and memory function change over the menopausal transition, when we believe that sex differences in memory aging emerge. By understanding healthy aging, we will better understand how the brain goes awry with age differently in men and women and who might be at highest risk for Alzheimer's disease later in life. (more…)

MedicalResearch.com Interview with: Peter Wise MD Charing Cross Hospital and Imperial College School of Medicine London, UK MedicalResearch.com: What is the background for this analysis? Response: As a medical ethicist, I wished to know how much patients with advanced – metastatic – cancer knew about the drugs that were being used to treat it. What were their perceptions of likely treatment success and how did that tally with our knowledge of what drugs could actually achieve – and at what cost to the body and to the pocket. Did patients actually have a choice – and how did the drugs get approved for use in the first place? (more…)
Author Interviews, JAMA, Ophthalmology, Pediatrics, Technology / 11.11.2016

MedicalResearch.com Interview with: Krista Kelly, PhD Postdoctoral Fellow Crystal Charity Ball Pediatric Vision Evaluation Center Retina Foundation of the Southwest Dallas, TX 75231 MedicalResearch.com: What is the background for this study? Response: Amblyopia is one of the most common causes of monocular impairment in children, affecting 1 or 2 children in every US classroom. Patching of the fellow eye has been used for decades to improve visual acuity in the amblyopic eye. But patching does not always restore normal vision and does not teach the two eyes to work together. A novel technique originally designed by Drs Robert Hess and Ben Thompson at McGill University that works to reduce interocular suppression by rebalancing the contrast between the eyes has shown promising results in amblyopic adults. Dr Eileen Birch at the Retina Foundation of the Southwest worked with Dr Hess to adapt this contrast re-balancing approach to an iPad game platform suitable for children. Her research showed that the games were successful in improving visual acuity in amblyopic children as well. However, these initial games were rudimentary and resulted in low compliance. (more…)
Author Interviews, Cancer Research, Immunotherapy / 11.11.2016

MedicalResearch.com Interview with: Dr. Michael Lotze, MD Chief Scientific Officer, Lion Biotechnologies San Carlos, CA 94070 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Adoptive cell therapy (ACT) with Tumor-infiltrating Lymphocytes (TIL) has shown promise in mediating cancer regression which rely on activation in vivo compared to other immunotherapies that utilize genetically modified T-cells. In TIL therapy, autologous administration of TIL expanded outside the body elicits a highly individualized, specific and potent attack against the tumor. Clinical trials conducted at the National Cancer Institute evaluating TIL therapy for the treatment of metastatic melanoma reported overall response rates of up to 56%. The durable responses observed in these metastatic melanoma patients as well as other patients with cervical cancer, cholangiocarcinoma, and head and neck cancer signal the potential for broader application of TIL therapy to treat patients with other solid tumors, currently an area of substantial unmet clinical need. Lion’s study, recently presented at the Society for Immunotherapy of Cancer, sought to demonstrate the feasibility of culturing and expanding TIL isolated from non-melanoma tumors. We were successful in culturing TIL from tumors obtained from bladder, cervical, head and neck, lung and triple negative breast cancer. (more…)
Author Interviews, OBGYNE, Pediatrics / 10.11.2016

MedicalResearch.com Interview with: Jason Bentley, MBiostat Doctoral Fellow Menzies Centre for Health Policy University of Sydney MedicalResearch.com: What is the background for this study? Response: Planned birth (labor induction or pre-labor caesarean section) is a decision to intervene and so determines a gestational age at birth that would have otherwise been later if pregnancy had progressed through to spontaneous labor. Significant changes in clinical practice have seen an increase in planned births before 39-40 completed week’s gestation from an increased use of primary and repeat cesarean section and a greater use of labor induction. At a population level this has resulted in a decrease in modal gestational age with planned birth accounting for almost half of births before 39-40 weeks. Clinical research has indicated that the threshold for planned birth and the gestational age for intervening has reduced. Numerous reasons have been given as justification for this including litigation, patient and provider perception of safety versus risk, reduced perinatal mortality, increased fetal monitoring, maternal age, obesity and convenience. There has also been the clinical perception that birth just before the optimal date carries little significant morbidity, with a focus on short-term risks to mother or baby only rather than longer-term outcomes. It is of paramount importance to ensure there are no unintended harms from such a significant shift in clinical practice. This study investigated whether the timing of planned birth was associated with poorer developmental outcomes at school age. (more…)
Author Interviews, Dermatology, JAMA, Melanoma / 10.11.2016

MedicalResearch.com Interview with: Caroline Watts | Research Fellow Cancer Epidemiology and Prevention Research Sydney School of Public Health Melanoma Institute Australia (MIA) investigator The University of Sydney MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Melanoma Patterns of Care study was a population-based observational study of physicians’ reported clinical management of 2727 patients diagnosed with an in situ or invasive primary melanoma over a 12-month period from October 2006 to 2007 in New South Wales, Australia. This paper investigated the differences between 1052 (39%) patients who were defined as higher risk owing to a family history of melanoma, multiple primary melanomas, or many nevi (moles) compared to patients who did not have any risk factors. We found that the higher-risk group had a younger mean age at diagnosis compared to those without risk factors, (62 vs 65 years, P < .001) which varied by type of risk factor (56 years for patients with a family history, 59 years for those with many nevi, and 69 years for those with a previous melanoma). These age differences were consistent across all body sites. Among higher-risk patients, those with many nevi were more likely to have melanoma on the trunk (41% vs 29%, P < .001), those with a family history of melanoma were more likely to have melanomas on the limbs (57%vs 42%, P < .001), and those with a personal history were more likely to have melanoma on the head and neck (21% vs 15%, P < .001).

Author Interviews, Hospital Acquired / 09.11.2016

MedicalResearch.com Interview with: Dusty Deringer Vice president of Patient Experience for Crothall Healthcare Compass One Healthcare MedicalResearch.com: What are the main findings from your new research? Response: Patients’ perceptions of a hospital’s cleanliness can have a major impact on their overall care and hospital experience. Specifically, the data show correlations between patients’ perceptions of room cleanliness and three important categories: the risk of hospital-acquired infections; a hospital’s score on the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey and scores on the HCAHPS teamwork indicators. The findings are important because patients are more likely to recommend a hospital they perceive to be clean. Therefore, it makes cleanliness a target for improvement for all hospitals. (more…)
Author Interviews, Breast Cancer, Chemotherapy, JAMA, Karolinski Institute / 09.11.2016

MedicalResearch.com Interview with: Jonas Bergh M.D, Ph.D. F.R.C.P. (London, UK) Professor of Oncology (Mimi Althainz´donation) Director Strategic Research Program in Cancer Karolinska Institutet Radiumhemmet, Karolinska University Hospital Stockholm, Swede MedicalResearch.com: What is the background for this study? Response: Present standard dosing of chemotherapy is aiming at a similar dose for each individual (similar effects and side-effects) , by calculating the dose per mg/m2 based on a formula originally established by du Bois (1916), based on body surface calculations by measuring height and weight. As I recall it, this was done on nine individuals… However, the body surface has very little to do with how you cytotoxic drugs are metabolized and excreted… in practice this means that chemotherapy dosing based on body surface area will result in under- or overdosing of quite a proposition of the patients… Please Google/run a PubMed research on H. Gurney in Australia, he and other have really expressed their concerns with our present chemotherapy dosing strategies. In our prospective adjuvant chemotherapy study of high risk breast cancer patients we tested a very well established standard chemotherapy regimen given every third week (FEC100 mg/m2 x 3+ docetaxel 100 mg/m2 x3) vs. our experimental arm given very second week in a dose dense fashion. We also tried to optimize the dosing, aiming at avoiding overdosing some patients at the first course and increase the dose for those without predefined toxicities. Therapy duration was similar in both groups, 15 weeks. Please see the end of the discussion in JAMA for the shortcomings with our study. (more…)

MedicalResearch.com Interview with: Borge G. Nordestgaard, MD, DMSc Professor, University of Copenhagen Chief Physician, Dept. Clinical Biochemistry, Herlev and Gentofte Hospital Copenhagen University Hospital Herlev, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Acute pancreatitis is an inflammatory disorder of the pancreas with gallstones and high-alcohol consumption as leading risk factors, while mild-to-moderately increased plasma triglycerides hitherto has been overlooked. We surprisingly found that the risk of developing acute pancreatitis was increased already from triglycerides of 175 mg/dL (2 mmol/L) and above. When triglycerides were above 443mg/dL (5mmol/L) the risk was increased a massive 9-fold. Interestingly, this risk was higher than the corresponding 3.4-fold higher risk for myocardial infarction.

Author Interviews, JAMA, OBGYNE, Pediatrics / 09.11.2016

MedicalResearch.com Interview with: Dr. Sharon Unger BSc, MD, FRCP Staff Neonatologist at Mount Sinai Hospital Associate Staff Neonatologist at The Hospital for Sick Children (SickKids) Associate Professor in the Department of Paediatrics at the University of Toronto. Medical Director of the Rogers Hixon Ontario Human Milk Bank and Dr. Deborah L. O’Connor PhD, RD Senior Associate Scientist in Physiology & Experimental Medicine SickKids and Professor Department of Nutritional Sciences at the University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Response: Babies who are born very early (before 32 weeks’ gestation) and/or at very low weights (less than 1,500 grams) are among the most fragile of all paediatric patients, typically facing serious medical issues and requiring care in a Neonatal Intensive Care Unit (NICU). In addition to underdeveloped organs and risk of neurodevelopmental issues, preterm and very low birth weight babies are at risk of a severe bowel emergency called necrotizing enterocolitis, which involves the damage and potential destruction of the intestinal tissue. This disease affects approximately six per cent of very low birth weight infants each year, making it one of the most common causes of death and long-term complications in this population. As a neonatologist and a PhD-trained dietitian, we have spent our careers working to improve outcomes for babies and supporting breastfeeding. While there is already strong evidence to suggest that breastfeeding is associated with a variety of benefits including reduced risk of childhood infections and may play a role in the prevention of overweight and diabetes, in healthy, full-term infants, we launched a research program a decade ago to figure out how to ensure the same advantage could be provided to vulnerable hospitalized infants, specifically very low birth weight infants. Breastfeeding initiation rates in Canada are now at all-time high for healthy newborns, but for many reasons related to preterm birth, up to two thirds of mothers of very low birth weight infants are unable to provide a sufficient volume of breast milk to their infant. A variety of factors may limit breast milk production in these cases, including immaturity of the breast cells that make milk, maternal illness, breast pump dependency, and stress. In addition to the health benefits attributed to mother’s milk for full-term, healthy infants, previous studies have shown that use of mother’s milk in very low birth weight infants is associated with a reduction in necrotizing enterocolitis. It is also associated with a reduction in severe infection, improved feeding tolerance and more rapid hospital discharge. Ten years ago, along with our inter-professional colleagues at 21 NICUs in the Greater Toronto and Hamilton areas, we began to examine whether using donor breast milk as a supplement to mother’s milk would improve health outcomes of very low birth weight infants when mother’s milk was not available.

Author Interviews, Cancer Research, Immunotherapy, Vaccine Studies / 09.11.2016

MedicalResearch.com Interview with: Leslie Chong Imugene Chief Operating Officer Armadale, Australia Leslie Chong Imugene Chief Operating Officer Armadale, Australia   MedicalResearch.com: What is the background for this study? How does HER-Vaxx work? • The technology originates from the Medical University of Vienna, one of Europe’s leading cancer institutes and was identified in 2012 by Dr Axel Hoos (Currently Sr. Vice President of Oncology R&D at GlaxoSmithKline, previous Clinical Lead on Ipilumimab at Bristol-Myers Squibb, a director at Imugene; his only Board seat worldwide) • HER-Vaxx is a peptide vaccine designed to treat tumours that over-express the HER2/neu receptor, such as gastric, breast, ovarian, lung and pancreatic cancers. The vaccine is constructed from various B Cell epitopes of HER2/neu. It has been shown in pre-clinical work and in a Phase 1 study to stimulate a potent polyclonal antibody response to HER2/neu, a commercially and clinically validated cancer target. HER-Vaxx’s successful Phase 1 study was in patients with metastatic breast cancer and the next stage of development will be a Phase 1b/2 study in patients with gastric cancer initiating in 2016.

Author Interviews, CDC, Pediatrics, Salt-Sodium / 08.11.2016

MedicalResearch.com Interview with: Zerleen S. Quader, MPH CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sodium reduction is considered a key public health strategy to reduce cardiovascular disease nationwide, and this study is the latest in ongoing CDC efforts to monitor U.S. sodium intake. Eating habits and taste for salt are established early in life by what children eat. Eating too much sodium can set them up for high blood pressure now and health problems later. Previous evidence suggests that one in nine children already has blood pressure above the normal range, and strong evidence has shown that reducing sodium intake reduces blood pressure – and lowering blood pressure lowers the risk of cardiovascular disease among adults. With voluntary efforts already underway by some manufacturers to lower the sodium and added sugar content in some of their products, these findings help provide a baseline to monitor changes in the food industry, as well as sodium intake among U.S. youth. We examined data from the 2011-2012 National Health and Nutrition Examination Survey (NHANES) to determine sodium intake by major food category, place and eating occasion. We found that average sodium intake among participants was 3,256 mg, and that doesn’t include salt added at the table. On the day of assessment, nearly 90 percent exceeded the upper level of sodium recommended for a healthy diet. • There were some variations based on age and gender. For example: o Average intake was highest among high school-aged children o Girls had significantly lower daily intake than boys (for example, 2,919 mg versus 3,584 mg) • In addition, we found that ten types of food make up nearly half of youth sodium intake nationwide, including pizza, bread, lunch meats and snack foods. We also analyzed where the foods were obtained and found that approximately 58 percent of sodium comes from store foods, 16 percent from fast food and pizza restaurants and 10 percent from school cafeteria foods. And when we looked at occasion, we discovered that 39 percent of sodium intake was consumed at dinner, 31 percent at lunch, 16 percent from snacks and 14 percent from breakfast. (more…)
Author Interviews, Blood Pressure - Hypertension / 08.11.2016

MedicalResearch.com Interview with: Alejandro de la Sierra, MD, PhD, FESC, FAHA Professor of Medicine Head, Internal Medicine Department Hospital Mutua Terrassa University of Barcelona, Spain MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Systolic Blood Pressure Intervention (SPRINT) trial has demonstrated that a strategy of systolic blood pressure (BP) reduction to a goal of 120 mmHg in selected hypertensive patients prevents the development of cardiovascular complications and mortality. The trial used automated office BP measurements. However, ambulatory BP monitoring (ABPM) has demonstrated to be superior to office BP in predicting cardiovascular events and mortality. We aimed to evaluate ambulatory BP values in hypertensive patients from the Spanish ABPM Registry who meet eligibility criteria for the SPRINT trial. The results indicated that one third of our hypertensive population met such eligibility criteria and that ABPM values were considerably lower than office BP, with 42% of subjects having daytime BP below 130 mmHg and 21% with 24-hour BP below 120 mmHg.

Author Interviews, Cost of Health Care, Diabetes, JAMA / 08.11.2016

MedicalResearch.com Interview with: Tara Gomes, MHSc Li Ka Shing Knowledge Institute, St Michael’s Hospital, The Institute for Clinical Evaluative Sciences Leslie Dan Faculty of Pharmacy Department of Health Policy, Management, and Evaluation University of Toronto, Toronto, Ontario, Canada MedicalResearch.com: What is the background for this study? What are the main findings? Response: In August 2013, the Ontario government introduced reimbursement limits for blood glucose test strips. Subsequent research has suggested that the provincial government saved $24 million in the first year after implementing this quantity limit policy. This study investigated whether these quantity limits led to any change in diabetes-related patient outcomes. We found that limiting the number of blood glucose test strips reimbursed by the government to levels recommended by the Canadian Diabetes Association had to no change in diabetes control (measured as rates of emergency department visits for hypoglycemia or hyperglycemia, and mean HbA1c) in the 1.5 years after implementation. Similarly, there was no worsening of patient outcomes in a subgroup of individuals who had been frequent users of test strips prior to the policy being announced. (more…)

MedicalResearch.com Interview with: Lisa Bailey-Davis, DEd, RD Assistant Professor, Department of Epidemiology and Health Services Research Associate Director, Obesity Institute Geisinger Health Systems Danville, PA 17822 MedicalResearch.com: What is the background for this study? What are the main findings? Response: National data from CDC suggest that 3.1% of 12-17 year olds self-reported using an antidepressant in 2005-2010, however we examined electronic health record orders at a large health system and found that antidepressants are ordered more frequently. Antidepressants were ordered for 7.2% of 13 year olds and 16.6% of 18 year olds in our population-representative data. Five or more cumulative months of antidepressant use was strongly associated with increased body mass index, particularly among older youths. At age 18 years, youth treated with 12 or more months of antidepressants were likely to be 2.1 kg heavier than youth without antidepressants. Depression diagnosis, independent, of antidepressants was also associated with higher body mass index. At age 12 years, youth with at least 1 depression diagnosis had a higher average BMI than youth without such diagnosis. (more…)
