Medical Research: What is the background for this study? What are the main findings?
Response: Despite evidence to suggest that the prevalence of childhood obesity in the UK has stabilized in recent years, we know that approximately one in five children start their school life either overweight or obese, increasing to one in three children by the last year in primary school. Our research was the first to undertake an in-depth analysis on the UK’s National Child Measurement Programme (NCMP) and retrospectively track the weights of individual children over a 7-year period. Our study included a sample of 1863 children in South Gloucestershire, Bristol in the UK.
Our results were found to be similar to cross sectional data with obesity prevalence approximately doubling between the first (4/5yrs old) and last year (10/11yrs old) of primary school. Our findings provide little reassurance that those children who are obese in early childhood ‘grow out of ’ excess adiposity. Including overweight, we found that 84% of obese children at Reception year went on to be either overweight or obese by Year 6. Although previous studies have failed to identify any significant differences in BMI change between boys and girls during mid-childhood, our research found that more boys than girls dropped a weight category (from overweight or obese) by the time they reached Year 6. We found that the odds ratios of being overweight (BMI ?85th percentile) or obese (?95th percentile) based on BMI at Reception were similar to published literature. Our data found children who are within the upper range of the healthy weight category (75th–85th percentile) at Reception had an increased risk of being overweight or obese by the time they reach year 6.

Medical Research: What is the background for this study? What are the main findings?
Response: We reviewed settlement agreements in malpractice claims closed by The University of Texas System as part of a larger study on incorporating patient perspectives into safety improvement funded by the Agency for Health Care Research and Quality. Over the five years studied, we found that 88.7% of the 124 settlement agreements that met our study criteria contained non-disclosure provisions, but with little standardization or consistency. Restrictions on disclosure, which selectively burdened patients and their families, seemed broader than needed to protect health care providers from disparagement or to avoid attracting additional litigation. Medical malpractice could happen to anyone at any time during your visit to your hospital. If you or a member of your family have been the victim of medical palpractice you might want to look into getting help from someone like this Tate Law Offices Ft. Worth Personal Injury Law Firm or a law firm that is local to you that might be able to help with your case.
Nearly half of the agreements (46.4%) prohibited disclosure of the underlying facts, which may be inconsistent with emerging principles of patient safety and compassionate care, and 26.4% prohibited reporting to regulatory bodies, a restriction that the health system subsequently eliminated in response to our findings. Settlements reached after tort reform took full effect in Texas had stricter non-disclosure provisions than earlier settlements, suggesting greater leverage by defendants notwithstanding the reduced risk of additional litigation.

Response: Moderate alcohol has repeatedly been linked to lower risk of developing diabetes, and among diabetics, those who drink moderately at at substantially lower risk for cardiovascular outcomes. However, there have been no long term trial of alcohol among diabetics. In this two-year randomized trial, we found that wine caused modest improvements in glucose metabolism and in blood lipid levels, with a somewhat greater benefit observed for red wine, for changes in lipids.

John LaPorte Given Professor of Immunology and Infectious Diseases
Harvard T.H. Chan School of Public Health
Department of Immunology and Infectious Diseases
Boston, Massachusetts
MedicalResearch: What is the background for this study? What are the main findings?
Dr. Duraisingh: The malaria parasite P. falciparum is one of the most important pathogens of humans, with enormous mortality resulting from blood-stage infections, when parasites replicate exponentially in red blood cells. Although anti-Plasmodial drugs are in clinical use, widespread and increasing parasite drug-resistance has contributed to an ongoing public health crisis, and we urgently need to find novel approaches to prevent and treat disease.
Targeting host red blood cell molecules presents an unexploited alternative. However, the highly differentiated and enucleated red blood cell poses a significant technical hurdle for genetic experimentation, due to the lack of a nucleus.
Here we have developed a novel, forward genetic screen to identify critical factors of malaria infection of red blood cells in an unbiased fashion. Our screen takes advantage of recent advances in human stem cell biology that enable the ex vivo culture of red blood cells from nucleated hematopoietic precursors which are amenable to in vitro genetics.
We have now identified a surface molecule CD55 (alias Decay-Accelerating Factor, DAF) as an essential host factor required for the invasion of red blood cells by P. falciparum. We demonstrate that this protein is required by all P. falciparum strains tested (laboratory and field) for invasion. Furthermore, we demonstrate that CD55 acts at the initial stage of invasion when the P. falciparum parasite attaches to the surface of the red blood cell.
Collectively, our findings indicate that CD55 is an ideal target for the development of new host-directed and vaccine therapeutics for malaria.

MedicalResearch: What is the background for this study? What are the main findings?
Dr. Joynt: While there is a great deal of optimism about the potential of Electronic Health Records (EHRs) to improve health care, there is little national data examining whether hospitals that have implemented EHRs have higher-quality care or better patient outcomes. We used national data on 626,473 patients with ischemic stroke to compare quality and outcomes between hospitals with versus without EHRs. We found no difference in quality of care, discharge home (a marker of good functional status), or in-hospital mortality between hospital with versus without EHRs. We did find that the chances of having a long length of stay were slightly lower in hospitals with EHRs than those without them.

MedicalResearch.com Interview with:
Bernadette A.M. Heemskerk-Gerritsen, Ph.D.
Department of Medical Oncology
Erasmus MC Cancer Institute
Roterdam, the Netherlands
Medical Research: What is the background for this study? What are the main findings?
Dr. Heemskerk-Gerritsen: Women with a BRCA1 or BRCA2 mutation have substantially higher risks of developing both primary and contralateral breast cancer (BC) and ovarian cancer than women from the general population. Options to reduce these increased cancer risks include risk-reducing mastectomy (RRM) and/or risk-reducing salpingo-oophorectomy (RRSO). The latter intervention obviously reduces the risk of developing ovarian cancer, but has been reported also to reduce the risk of developing a subsequent breast cancer with approximately 50%. However, studies on the efficacy of risk-reducing surgery in BRCA1/2 mutation carriers are confined to observational studies, thus challenging several methodological issues. Consequently, previous studies on breast cancer risk-reduction after RRSO may have been influenced by bias associated with selection of study subjects, bias associated with start of follow-up, or by confounding, and breast cancer risk-reduction may have been overestimated.
In the current study, we revisited the association between risk-reducing salpingo-oophorectomy and breast cancer risk in BRCA1/2 mutation carriers, focusing on the impact of different analytical methods and potential types of bias.
First, we replicated the analyses of four previously performed studies, to examine if our Dutch cohort was comparable with the cohorts used in the previous studies. We replicated the approximately 50% breast cancer risk reduction after RRSO in the Dutch cohort.
Second, we estimated the effect of RRSO on breast cancer risk in the Dutch cohort using a revised analytical approach for observational studies in BRCA1/2 mutation carriers in order to minimize bias as much as possible. Using this method of analysis, we found no evidence of first BC risk-reduction after RRSO in BRCA1/2 mutation carriers.

MedicalResearch.com Interview with:
Dr. Brian Rowe, MD, MSc, CCFP(EM), FCCP
Professor, Department of Emergency Medicine
University of Alberta, Edmonton, Alberta, Canada
MedicalResearch: What is the background for this study?
Dr. Rowe: Frequent users are also called “familiar faces” or “heavy users” and they represent an important sub-group of patients in the emergency setting, with often complex needs that contribute to overcrowding and excess health care costs. The evidence suggests that frequent users account for up to one in 12 patients seeking emergency care, and for around one in four of all visits.
MedicalResearch: What are the main findings?
Dr. Rowe: Frequent users of emergency department care are more than twice as likely to die, be admitted to hospital, or require other outpatient treatment as infrequent users, concludes an analysis of the available evidence, published in Emergency Medicine Journal.
These conclusions are based on a thorough search of seven electronic databases of relevant research relating to the frequency and outcomes of emergency department use by adults. Out of a total of more than 4000 potential studies, 31 relevant research reports published between 1990 and 2013 were included in the final analysis. Frequent users were variably defined as visiting emergency care departments from four or more times up to 20 times a year.
Among the seven studies looking at deaths, the analysis showed that frequent attenders at emergency care departments were more than twice as likely to die as those who rarely sought emergency care. Most of the studies included hospital admission as an outcome, and these showed that frequent users were around 2.5 times as likely to be admitted as infrequent users. Ten studies looked at use of other hospital outpatient care, and these showed that frequent users were more than 2.5 times as likely to require at least one outpatient clinic after their visit to the emergency care department.

Director, Sleep and Performance Research Center
Research Professor, College of Medical Sciences
Washington State University Spokane, Spokane, WA
On behalf of the authors: Paul Whitney PhD, John Hinson PhD, Melinda Jackson PhD, Hans Van Dongen PhD
MedicalResearch: What is the background for this study? What are the main findings?
Research: Our main interest is in better understanding why people sometimes are able to manage perfectly well with sleep loss, while at other times sleep loss can have profoundly negative effects. We found that sleep deprivation reduces the effectiveness of signals used to tell when you are right or wrong, an effect we labeled feedback blunting.
Subjects in the study performed a decision making task that was simple but required feedback, i.e., a signal indicating the response was correct or incorrect, to perform correctly. We found that people who were sleep deprived were no longer able to use the feedback information to make correct responses. And when people had to adapt to unexpected changes in when to respond, sleep deprived people were completely unable to adapt to these changing circumstances.
The finding of feedback blunting in this study indicates that people who are sleep deprived not only have trouble sustaining attention to details in the environment (a well established effect of sleep loss), they also have trouble changing the focus of attention to deal with changing circumstances.
An interesting paradox in the research literature has been that people have been shown in many circumstances to perform complex tasks at a very high level while sleep deprived. Yet, we know from real-world experience that sleep deprived people can make catastrophic, life-threatening decisions that they would never have made if they were well rested. The current study is the first to shed light on this issue. It showed that sleep deprived people who get feedback, telling them that their actions are not effective, are less capable of changing their behavior.
The study is part of a line of research in which we are trying to identify how sleep loss changes specific components of cognition, and how these changes may lead to serious problems in everyday life activities. Being able to study and understand these effects of sleep deprivation under controlled conditions is an important step toward preventing human error under real world conditions.

Medical Research: What are the main findings?
Response: The diet-heart hypothesis has been researched during decades. A common mistake was to assume that a high intake of all types of fat was detrimental for cardiovascular health and could cause heart attacks and strokes. Therefore a low-fat diet was proposed as the best way to prevent heart attacks and strokes. This was wrong.
Alternatively, the Mediterranean diet, rich in fat from natural vegetable sources (olive oil, tree nuts), was also considered a healthy dietary pattern.
However, most of the evidence to support these benefits of a fat-rich Mediterranean diet came from observational studies and no randomized clinical trial had ever assessed the Mediterranean diet in PRIMARY prevention (i.e. in initially healthy people) (more…)
MedicalResearch.com Interview with:
Rebecca Todd Ph.D.
Assistant Professor University of British Columbia
Department of Psychology
Centre for Interactive Research on Sustainability
Vancouver, BC
Medical Research: What is the background for this study? What are the main findings?
Dr. Todd: This study brings together two lines of research. First, a couple of years ago my colleagues and I reported that in general people literally see emotional aspects of the world as more vivid - as if they burn more brightly on the eye - than mundane things. We call this effect emotionally enhanced vividness, or EEV. Here we wanted to look at how this phenomenon of emotionally enhanced vividness might differ between individuals.
Second, in another previous study we found that people who carry a very common variation in the ADRA2b gene, which influences levels of norepinephrine (a neuromodulator in the brain that is important to the stress response and for emotional influences on memory) were more likely to have their attention captured by emotionally relevant aspects of the world. We also found that how arousing they perceived an event to be at the time it happened predicted how well they remembered it better than for people who did not carry this variation. Here we continued to examine what is unique to this group of people by testing to see if they showed higher levels of the other phenomenon we had found, emotionally enhanced vividness, and what patterns of brain activation would play a role.

Cambridge
Medical Research: What is the background for this study? What are the main findings?
Response: Consumption of sugar-sweetened beverages is a major contributor to obesity, particularly in children. Recent systematic reviews provide good evidence that reducing portion size reduces consumption. Similarly, evidence suggests that container shapes and product placement in supermarkets can influence consumption. The public acceptability of "nudging" -- altering properties such as the size, the shape, and location of sugar-sweetened beverages -- to improve public health is unknown. Here we compared the acceptability in UK and USA samples of government interventions to reduce consumption of sugar-sweetened beverages: three nudge interventions (limiting portion size, changing container shape, and changing shelf location) and two traditional interventions (increased taxation and an education campaign).
We found that for the majority of UK and USA samples, the education campaign and the three nudge interventions were acceptable, with education attracting most support. By contrast, only a minority of participants supported taxation.

Medical Research: What is the background for this study? What are the main findings?
Dr. McKinney: The current study evaluated outcomes of patients admitted to New Jersey hospitals with hemorrhagic stroke, including intracerebral hemorrhage (bleeding into the brain) and subarachnoid hemorrhage (bleeding along the surface of the brain) between 1996 and 2012 using the Myocardial Infarction Data Acquisition System (MIDAS) administrative database. The New Jersey Department of Health and Senior Services designates certain hospitals as comprehensive stroke centers (CSCs). We found that patients admitted to comprehensive stroke centers with hemorrhagic stroke were less likely to die than those admitted to other hospital types. This was particularly true for those patients admitted with subarachnoid hemorrhage, which is usually caused by a ruptured aneurysm.

Ishak Mansi, MD
Staff Internist, VA North Texas Health System.
Professor in Department of Medicine &
Department of Clinical Sciences, Division of Outcomes and Health services Research, University of Texas Southwestern, Dallas, TX
MedicalResearch: What is the background for this study? What are the main findings?
Dr. Mansi: Statin use is associated with increased incidence of diabetes, and possibly increased body weight, and less exercise capacity. Data on the long-term effects of these associations in healthy adults are very limited. Additionally, the effects of these associations on diabetic complications have not been adequately studied.
Dr. Mansi at VA North Texas Health System, Dallas and Professor of Medicine and Clinical Sciences at the University of Texas Southwestern, Dallas, TX and his colleagues found that among generally healthy individuals, statin-users in comparison to non-users had a higher odds of being diagnosed with new onset diabetes, diabetes with complications, and overweight/obesity.
The researchers examined the records of tens of thousands of Tricare beneficiaries, during the period from 10/1/2003 to 3/1/2012. After excluding patients who had at baseline a preexisting cardiovascular diseases or severe chronic diseases that may be life-limiting (including diabetes mellitus), they identified a cohort of 25,970 patients as “healthy cohort”. They, further, matched 3,351 statins-users and 3,351 nonusers on several baseline characteristics to ensure comparability.
There are 3 main important findings for our study:

Houston, Texas
Medical Research: What is the background for this study? What are the main findings?
Dr. Mir: The past few decades have seen an alarming rise in opioid use in the United States, and the negative consequences are dramatically increasing. The US represents less than 5% of the world's population, yet consumes 80% of the global opioid supply. Management of pain is an important part of patient care, however, the increased usage of opioids for the treatment of pain has led to several unanticipated aftereffects for individual patients and for society at large.
Orthopaedic surgeons are the third highest prescribers of opioid prescriptions among physicians in the United States. Orthopaedic patients can experience a tremendous amount of pain with acute injuries and chronic conditions, and the treatment plan may involve opioid prescriptions for relief of discomfort. A significant number of orthopaedic patients and their families are at risk for repercussions from opioid use. We must work together to decrease the use of opioids for musculoskeletal pain.
Clinicians should aim to control pain and improve patient satisfaction while avoiding overprescribing opioids. A comprehensive strategy of risk assessment is needed to identify patients who may be at risk for opioid abuse. Objective measures including patient history, recognition of aberrant behavior, urine drug testing, state prescription drug–monitoring programs, and opioid risk-assessment screening tools may be necessary in select cases.

MedicalResearch.com Interview
Dr. Ludovic Desvignes PhD.
Assistant Professor, Departments of Medicine and Pathology
NYU Langone Medical Center
MedicalResearch: What is the background for this study?
Dr. Desvignes: This study is the result of a collaboration at NYU Langone Medical Center, between the laboratories of Dr. Stefan Feske and Dr. Joel Ernst, my mentor. Dr. Feske and colleagues had developed a mouse model of rare, inherited mutations he had identified in infants. These mutations occur in the genes for STIM1 and ORAI1, which are crucial for calcium flux in cells of the immune system. The young patients affected by these mutations suffer from severe, recurrent and chronic infections that often cause death before their first birthday. In particular, some of these patients cannot control infection with BCG, which is a normally innocuous strain of mycobacteria administered to protect against tuberculosis (TB). TB is a chronic infection and one of the leading causes of infection-related death worldwide. Going into this study, Dr. Feske and colleagues knew that without functional calcium channels, immune cells do not function properly. However, they did not fully understand how these channels contribute to immune responses to infectious pathogens in a living organism and in particular, for pathogens that cause chronic infections such as TB. This is why Dr. Ernst and I collaborated with Dr. Feske and provided him with our clinical and research expertise in TB.
MedicalResearch: What are the main findings?
Dr. Desvignes: Dr. Feske’s mice are genetically engineered to lack STIM1 in a certain type of immune cells, known as T cells or T lymphocytes. We infected these mice with Mycobacterium tuberculosis, the bacterium causing TB. Mycobacterium tuberculosis causes chronic infection by manipulating the immune system even in healthy people. The first very surprising result of our study was that mice lacking calcium flux in T cells handled acute TB fairly well. Only during the chronic phase of infection did they become unable to control mycobacterial growth and developed a strong inflammation in their lungs, which was due to an infiltration by different types of immune cells, including T cells. We discovered that the accumulation of STIM1-deficient T cells in the lungs resulted from the cells’ inability to die, which is a normal mechanism to limit an immune response and prevent excessive inflammation.
Another immune control mechanism that failed in the absence of STIM1 is mediated by a subset of T cells called induced regulatory T cells, or iTreg cells. These cells are essential to prevent normal immune responses from going “overboard” by suppressing the functions of other immune cells, including T cells. We found that calcium signals are required for the development of iTreg cells and that their numbers were strongly reduced in the lungs of infected STIM1-deficient mice. We therefore think that the lack of iTreg cells in the absence of STIM1 contributes to the severe lung inflammation in chronic TB.
The third finding that really surprised us was that T cells accumulating in the lungs of STIM1-deficient mice produced large amounts of a protein called interferon gamma. While interferon gamma is required to control Mycobacterium tuberculosis, it is also a very potent promoter of inflammation and too much of it can lead to tissue damage. Dr. Feske and colleagues had previously observed that calcium fluxes promote the production of interferon gamma in T cells cultured in vitro and we expected the STIM1-deficient T cells to be defective in the production of that protein. During chronic TB, however, calcium signaling turned out to be not only dispensable for the production of interferon gamma by T cells but it was actually required to limit its production and thus, to control inflammation.

MedicalResearch.com Interview with:
Dmitry Kissin, MD
Health scientist
CDC Division of Reproductive Health
Medical Research: What is the background for this study?
Dr. Kissin: Due to the frequent transfer of more than one embryo during assisted reproductive technology (ART) treatments, such as in vitro fertilization (IVF), many ART-conceived children are born as multiples (twins, triplets and higher order). Multiple births, even twins, carry increased risk for both mothers and children. In the U.S., the practice guidelines published by the American Society for Reproductive Medicine (ASRM) and the Society for Assisted Reproductive Technology (SART) provide recommendations on how many embryos to transfer in order to balance safety with the effectiveness of assisted reproductive technology. In an effort to reduce multiple births and associated complications, it is important to evaluate embryo transfer practices that contribute to these outcomes.
Medical Research: What are the main findings?
Dr. Kissin: Using data from the CDC’s National ART Surveillance System (NASS), we found that the majority of ART-related multiple births in the U.S. resulted from assisted reproductive technology cycles practiced in accordance with ASRM/SART guidelines and involved the transfer of two embryos. Almost half of ART-related multiple births resulted from transferring two fresh blastocysts (embryos cultured for 5/6 days) to favorable- or average-prognosis patients less than 35 years and donor-egg recipients, or two frozen/thawed embryos to patients less than 35 years.

MedicalResearch.com Interview with:
Ahmad M. Khalil, PhD
Assistant professor, Department of Genetics and Genome Sciences
Case Western Reserve University School of Medicine
MedicalResearch: What is the background for this study? What are the main findings?
Dr. Khalil: This study aimed to identify other genes that work synergistically with the oncogene HER2 in HER2positive (HER+) breast cancer. The gene HER2 is amplified in those patients, which results in excess activities that promote uncontrolled cell growth. There are drugs that target HER2 and diminish its activity. However, these drugs can work initially, but patients relapse; or sometimes, the drugs don't work at all in some patients.
Thus, by identifying other genes that work synergistically with the HER2 gene, we now have more genes to target by various drugs or compounds to destroy the tumor. The challenge was how to identify the key genes that work synergistically with HER2, especially in human subjects. To that end, we used clinical samples from a clinical trial of a drug that is known to inhibit HER2 activity to identify those genes. To further refine our list, we used cell culture models of the disease to also inhibit HER2. By combining those data sets, we identified 44 protein-coding genes.
Next, we wanted to make sure that those genes stand a third independent filter. For that part, we interrogated those 44 genes in HER2+ tumors vs matched normal tissues from The Cancer Genome Atlas database — a collection of hundreds of tumors and normal tissues. Of the 44 genes, 35 genes passed this third filter. By examining the known functions of those genes, we can deduce that those genes work cooperatively with HER2 to promote carcinogenesis.
There are currently known drugs that target some of those genes. We will use these drugs in combination with a drug that target HER2 to determine if the combination works better at destroying the tumor entirely.
Lastly, we found that a special type of genes that we previously discovered, called lincRNAs, could also affect the oncogenic activity of HER2. These lincRNAs can also be targeted with HER2 to eliminate the tumor. (more…)
MedicalResearch.com Interview with:
Karoline Mortensen, Ph.D.
Assistant Professor
Department of Health Services Administration
University of Maryland
College Park, MD
Medical Research: What is the background for this study?
Dr. Mortensen: For twenty years, use of hospital emergency departments has been on the rise in the United States, particularly among low-income patients who face barriers to accessing health care outside of hospitals including not having an identifiable primary health care provider. Almost half of emergency room visits are considered “avoidable.” The Emergency Department-Primary Care Connect Initiative of the Primary Care Coalition, which ran from 2009 through 2011, linked low-income uninsured and Medicaid patients to safety-net health clinics.
Medical Research: What are the main findings?
Dr. Mortensen: “Our study found that uninsured patients with chronic health issues – such as those suffering from hypertension, diabetes, asthma, COPD, congestive heart failure, depression or anxiety – relied less on the emergency department after they were linked to a local health clinic for ongoing care,” says Dr. Karoline Mortensen, assistant professor of health services administration at the University of Maryland School of Public Health and senior researcher. “Connecting patients to primary care and expanding the availability of these safety-net clinics could reduce emergency department visits and provide better continuity of care for vulnerable populations.”

MedicalResearch.com Interview with:
Kristian Kragholm, MD, PhD-student
Cardiovascular Research Center,
Department of Anesthesiology,
Aalborg University Hospital
Medical Research: What is the background for this study?
Dr. Kragholm: During 2001-2010 in Denmark, survival to 30 days and 1 year more than doubled. Whether this substantial improvement in survival was accompanied by good functional recovery in survivors was not clear. Discharge neurological status or post-discharge follow-up assessments were not systematically recorded in Denmark but through nationwide registries employment outcomes were available. Therefore, we examined return to work as a marker of favorable neurological outcome in 30-day survivors of out-of-hospital cardiac arrest in a nationwide study in Denmark between 2001-2011.
Medical Research: What are the main findings?
Dr. Kragholm: More than 75% of all 30-day out-of-hospital survivors in Denmark during 2001-2011 who were employed prior to arrest returned to work
Not only did the majority of these survivors return to work, survivors also sustained work without any long-term sick absences for a median time of 3 years and maintained the same income after arrest as before arrest.
Finally, relative to survivors who did not receive bystander cardiopulmonary resuscitation (CPR), chances for return to work were increased by approximately 40% if bystanders had provided CPR in multivariable adjusted modeling. (more…)
