Rada K. Dagher, Ph.D.
Assistant Professor

College Park, MD 20742
MedicalResearch: What is the background for this study?
Dr. Dagher: In the United States, 51% of all pregnancies are unintended, and these happen disproportionately among racial and ethnic minorities. For example, in 2008, rates of unintended pregnancies were 69% among African American women, 56% among Hispanic women, and 40% among White women. Our study utilized 2006-2010 data from a nationally representative dataset, the National Survey of Family Growth, to investigate the reasons behind these racial/ethnic disparities.
MedicalResearch: What are the main findings of this study?
Dr. Dagher: The main findings of this study are as follows. Age and marital status differences explained both racial and ethnic disparities, where being single and younger than 20 years old at the time of conception contributed to the differences in unintended pregnancy between African American and White women, and between Hispanic and White women. However, there were also unique factors explaining the differences in unintended pregnancy between African Americans and Whites (respondent’s mother’s age at first birth, income, and insurance status) and the differences between Hispanics and Whites (U.S. born status and educational level). These findings provide support for culturally-tailored public health interventions that target at-risk groups of women such as younger, unmarried, lower income, lower educated, non-U.S. born women and those with public insurance, in order to reduce racial/ethnic disparities in unintended pregnancy.
MedicalResearch: What should clinicians and patients take away from your report?
Dr. Dagher: Our findings suggest that interventions to reduce racial and ethnic differences in unintended pregnancy should take into account multiple factors at multiple levels of influence. For example, at the policy level, the Affordable Care Act has mandated that health plans cover women’s preventative health care, including contraceptives, without cost sharing. Thus, primary care providers could educate their patients about these new policy provisions and encourage them to take advantage of them, especially patients at higher risk of unintended pregnancy such as women who are younger than 20, unmarried, non-U.S. born, have lower income, and those with public insurance.

Medical Research: What is the background for this study?
Dr. Ratanawongsa: Many people are concerned about the growing intrusion of computers into the patient-provider relationship. Touted as systems that will make care safer and more cost-effective, electronic health records (EHRs) have proliferated rapidly across the country, fueled by HITECH funding. However, some health care professionals feel like computers keep them from connecting with their patients. Also prior research has shown that computer use can change communication in the exam room and shift agenda from patients' concerns toward medical talk.
Safety net patients already face communication barriers in routine care, particularly language and literacy barriers. Although EHRs could help improve care and communication with these vulnerable patients by helping clinicians fill in the gaps (e.g., what happened in the ED, what medication were you given by that specialist), EHRs could also worsen communication by drawing clinicians' focus away from patients during visits.

Gordon C S Smith, MD PhD DSc FMedSci
Professor & Head of Department,
Obstetrics and Gynaecology,
Cambridge University

Medical Research: What were the key findings of the study?
Dr. Smith: We demonstrated that using ultrasound to scan all women in the last 3 months of pregnancy increased the detection of small babies. Our routine approach to antenatal care identified 1 in 5 small babies. Our research approach on the same patients, where all women were scanned in the last third of pregnancy, resulted in 3 in 5 small babies being detected.
We also found that, when we identified small babies, there was a scan measurement which helped us to distinguish which of those small babies were at increased risk of complications.
Medical Research: What's the problem with small babies?
Dr. Smith: We have known for many years that small babies are at increased risk of subsequent complications, both in the short term and long term. For example, they are more likely than normal sized babies to have difficulties during labour due to shortage of oxygen.
We assume that this is because their growth has been restricted. This leads to them being less well prepared to face the stress of labour. We think that the poor growth usually occurs because of a problem in the way the placenta functions. The placenta, also known as the afterbirth, is the organ which allows the transfer of nutrients and oxygen to the baby. If the placenta isn’t functioning properly it is likely to impair the growth of the baby in the womb.
If we suspect during a pregnancy that the baby is small, it influences a number of aspects of the care of the mother. For example, we might deliver the baby earlier, we might recommend delivery in a high risk unit. It might also influence decisions about whether a mother has a caesarean delivery, or how the baby is monitored during labour.

MedicalResearch.com Interview with:
Lori Daniels, MD, MAS, FACC
Professor of Medicine
Director, Coronary Care Unit
UCSD Division of Cardiology
Sulpizio Cardiovascular Center
La Jolla, CA
Medical Research: What is the background for this study?
Dr. Daniels: A large number of individuals who are at risk for developing cardiovascular disease (CVD) may not be identified as “at risk” by traditional screening methods. Blood-based biomarkers provide a possible way, in conjunction with traditional risk factor screening, to assess risk in individuals. Two such biomarkers which are gaining widespread attention are NT-proBNP and cardiac troponin T (TnT). NT-proBNP is secreted by cardiac muscle cells in response to stretch, while TnT is consider a marker of cardiac cellular damage. Previous studies have shown that each of these markers is associated with long-term risk of cardiovascular outcomes in the general population. Race and ethnicity have been shown to affect the levels of these markers, and whether these markers are equally predictive of future cardiovascular risk in various ethnic groups has not been well studied.
The Multi-Ethnic Study of Atherosclerosis (MESA) is an NIH-funded, multicenter, prospective, population-based study of white, black, Hispanic, and Chinese individuals without clinical CVD at baseline. Participants had blood drawn at a baseline study visit in 2000-2002, and again several years later, in 2004-2005. They have been followed for the development of CVD since then.
The purpose of this study was to learn whether NT-proBNP (single and serial measures) and TnT are predictive of incident cardiovascular disease in a diverse cohort of 5592 participants from the MESA. We also wanted to learn whether the addition of these biomarkers to established CVD risk prediction scores, including the 2013 American College of Cardiology (ACC)/American Heart Association (AHA) Pooled Cohort Risk Equation and the Framingham Risk Score, could improve performance of the risk score.

Medical Research: What is the background for this study?
Dr. Thompson: Our investigation was part of the longitudinal Infant Development and Environment and Lifestyle (IDEAL) study that was designed to investigate the effect of prenatal methamphetamine exposure on neurodevelopment. Although the negative impact of prenatal drug exposure on a wide range of neurodevelopmental outcomes such cognitive and motor function is established, the effect on vision is not well understood. To address this issue, vision testing was conducted when children in the New Zealand arm of the IDEAL study turned four and half years of age.
Although the primary focus of the IDEAL study was the impact of methamphetamine on neurodevelopment, the majority of children enrolled in the study were exposed to a range of different drugs prenatally including marijuana, nicotine and alcohol. Many children were exposed to multiple drugs. This allowed us to investigate the impact of individual drugs and their combination on the children’s visual development.
Alongside standard clinical vision tests such as visual acuity (the ‘sharpness’ of vision) and stereopsis (3D vision), we also tested the children’s ability to process complex moving patterns. This test, known as global motion perception, targets a specific network of higher-level visual areas in the brain that are thought to be particularly vulnerable to neurodevelopmental risk factors.

Prof. Jean-Yves Maillard
Professor of Pharmaceutical Microbiology

Medical Research: What is the background for this study? What are the main findings?
Prof. Maillard: Environmental surfaces in healthcare and other settings become contaminated with a variety of infectious agents which may survive long enough to infect susceptible hosts, either directly or through secondary vehicles such as hands. Therefore, routine decontamination of environmental surfaces, in particular those that are frequently touched, is crucial to reduce the risk of infections. Such decontamination is often performed by wiping the target surface with disinfectant-soaked or pre-wetted wipes. However, the label claims of wipes marketed for this purpose are often based upon testing that does not reflect their field use, where contact times are frequently no more than a few seconds with wide variations in the pressure applied during wiping. In addition, wipes impregnated with a disinfectant or detergent can potentially transfer microbial contaminants to a wider area, when the same wipe is used on multiple surfaces.
A device called the ‘Wiperator’ was invented to address these issues. It can be used to test wipes with predetermined pressures, wiping times and number of wiping strokes, using a standardized rotary action. It can not only assess the decontaminating efficiency of the test wipe, but also its ability to transfer the acquired contamination to clean surfaces. The test procedure developed using the device is now a standard (E2967) of ASTM International, a highly-respected standards-setting organization.
The Wiperator was used in a multi-laboratory collaborative to test commercially-available wipes for their ability to decontaminate metal disks that had been experimentally-contaminated with vegetative bacteria representing healthcare-associated pathogens. The used wipes were subsequently tested for their potential to transfer viable bacteria to clean surfaces. The contact time for wiping and transfer was 10 seconds. Only one of the wipes tested reduced the contamination to an undetectable level while not transferring any viable bacteria to a clean surface. All others left behind detectable levels of contamination on the wiped disks and transferred the contamination to clean surfaces.

Arri Coomarasamy, MBChB, MD, FRCOG

Medical Research: What is the background for this study? What are the main findings?
Professor Coomarasamy: Progesterone is a natural hormone that is essential to maintain a healthy pregnancy, and more than 60 years ago clinicians and researchers began to ask if progesterone supplementation in the first trimester of pregnancy could help to reduce the risk of miscarriage for women with a history of recurrent miscarriage. The evidence achieved in some small controlled clinical trials conducted before the PROMISE (progesterone in recurrent miscarriage) trial suggested a benefit from progesterone therapy, but without sufficient certainty to usefully guide clinical practice.
Five years after it began, the PROMISE trial has provided a definitive result. It is clear, it is important, and it is not the result that many anticipated. Our study of more than 800 women with a history of unexplained recurrent miscarriage has shown that those who received progesterone treatment in early pregnancy were no less likely to miscarry than those who received a placebo (or dummy treatment). This was true whatever their age, ethnicity, and medical history.

Medical Research: What is the background for this study? What are the main findings?
Dr. Storebø: Despite widespread use of methylphenidate for the treatment of children and adolescents with attention deficit hyperactivity disorder (ADHD), a comprehensive systematic review of its benefits and harms has not yet been conducted. Over the past 15 years, several reviews investigating the efficacy of methylphenidate for ADHD (with or without meta-analyses) have been published. Each of these reviews, however, has several shortcomings and these are described in detail in the review. The most important concerns are that none of these reviews are based on a pre-published protocol, and most assessed neither the risk of bias (systematic errors) of included trials nor adverse events. Moreover, none of these reviews considered the risk of random errors. Therefore, their interpretation of findings is unlikely to have taken into account the poor reporting of adverse events, the impact of combining data from small trial samples, or the impact of risk of bias on their analyses; information about adverse events is also missing from several RCTs. Because of this it is our opinion that these previous reviews might have overestimated the true treatment effect.
We found that Methylphenidate may improve ADHD symptoms, general behaviour and quality of life in children and adolescents aged 18 years and younger with ADHD. We rated the evidence to be of very low quality and, as a result, we cannot be certain about the magnitude of the effects from the meta-analyses. The evidence is limited by serious risk of bias in the included trials, under-reporting of relevant outcome data, and a high level of statistical variation between the results. We found no evidence for serious adverse events, but a lot of non-serious adverse events. Most of these are well known but the number of adverse events might even be higher than the number we found due to underreporting of adverse events. We know very little about the long term effects or harms as most of the trials in our review did not measure outcomes beyond 6 months. The risk of rare, serious adverse events seem low over the short duration of follow-up of the trials that reported on harms, but in general there was inadequate reporting of adverse events in many trials.

Medical Research: What is the background for this study? What are the main findings?
Dr. Pandey: Pulmonary artery (PA) catheters have been used for invasive bedside hemodynamic monitoring for past four decades. The ESCAPE trial, published in October 2005, demonstrated that use of Pulmonary Artery catheter was not associated with a significant improvement in clinical outcomes of patients with heart failure. Accordingly, the current ACC/AHA guidelines discourage the routine use of PA catheter for routine management of acute heart failure in absence of cardiogenic shock or respiratory failure (Class III). Despite the significant evolution of available evidence base and guideline recommendations regarding use of Pulmonary Artery catheters, national patterns of PA catheter utilization in hospitalized heart failure patients remain unknown.
In this study, we observed that use of PA catheter among patients with heart failure decline significantly in the Pre-ESCAPE era (2001 – 2006) followed by a consistent increase in its use in the Post-ESCAPE era (2007-2012). We also observed that the increase in use of Pulmonary Artery catheters is most significant among heart failure patients without underlying cardiogenic shock or respiratory failure.

Grant S Schulert MD, PhD
Clinical Fellow, Division of Rheumatology

Medical Research: What is the background for this study? What are the main findings?
Dr. Schulert: Influenza infection causes millions of illnesses annually, but most of those are relatively mild. In a subset of cases, patients can become critically ill, even if they are relatively young and healthy. Several previous reports had observed in these critically ill patients features of a hyperinflammatory syndrome known as HLH (hemophagocytic lymphohistiocytosis) or MAS (macrophage activation syndrome). This hyperinflammation can be triggered by other infections as well as in a subtype of juvenile arthritis, but there is also a familial form occurring in early childhood with known genetic causes. Our questions with this study were
1) how often are features consistent with HLH/MAS seen in fatal H1N1 influenza infections and
2) do patients with fatal H1N1 infection have genetic mutations associated with HLH/MAS?
Our collaborator Paul Harms, MD, and his team at the Michigan Center for Translational Pathology, University of Michigan Medical School identified 16 cases of fatal H1N1 influenza infection. Based on their clinical features, between 41-88% of these patients could be categorized as having a hyperinflammatory HLH/MAS. We then used processed tissue samples from the patients for whole exome genetic sequencing, which reads the entire genetic code of every gene in a person. Five patients carried mutations in genes which cause HLH, and several others carried mutations in genes linked to MAS. This suggests that there may be genetic risk factors for developing fatal hyperinflammatory syndromes in H1N1 infection.

MedicalResearch.com Interview with:
Xuesong Han, PhD
Director, Surveillance and Health Services Research
American Cancer Society, Inc.
Atlanta, GA 3030
Medical Research: What is the background for this study? What are the main findings?
Dr. Han: People with private insurance are more likely to be screened and more likely to be diagnosed at an early stage of cancer. An early provision of the Affordable Care Act implemented in September 2010 allows young adults to remain on their parents’ health insurance plan until age 26 years, following which there has been an increase in private insurance coverage among young adults aged 19-25 years. For young adults, the uterine cervix is the only cancer site for which screening is recommended with a starting age of 21 years, and diagnosis of cervical cancer at early stages allows use of fertility-sparing treatment.
Using data before and after the dependent coverage expansion provision of ACA, we found that compared with 26-34 year-olds who were not affected by the policy change, women 21-25 years of age experienced a net increase of 9 percentage points in early stage disease and 11.9 percentage points in receipt of fertility-sparing treatment.
MedicalResearch.com Interview with:
Dr. Ffion C Davies
Consultant in Emergency Medicine & Paediatric Lead
University Hospitals of Leicester NHS Trust
Leicester Royal Infirmary
Leicester UK
Medical Research: What is the background for this study?
Dr. Davies: This study is from the Trauma Audit Research Network data, which is a major trauma database receiving data from nearly all hospitals in England and Wales. A 2012 TARN report on major trauma in children showed a peak of injuries resulting from child abuse in the younger age group. In this study we analysed the database in more detail, in order to profile this peak of injuries from non-accidental injury (NAI).
Medical Research: What are the main findings?
Dr. Davies: The main findings are that severe injury and death resulting from non-accidental injury occurs nearly always in the under 5 year old age group, and 75% of cases are under 1 year old. This contrasts with reports in the media, whereby high profile deaths in children from non-accidental injury are often older children. This probably reflects reporting bias, because those children experienced a prolonged period of abuse, despite involvement of health and social services. Our study shows that very small infants are the most likely to die, or to sustain severe head injuries.

MedicalResearch.com Interview with:
Catherine Mewborn, B.A.
Neuropsychology and Memory Assessment Laboratory
Department of Psychology
University of Georgia
Medical Research: What is the background for this study?
Response: Vision and cognitive functioning both tend to decline as individuals age. Processing speed, or the speed at which an individual can process information, is particularly vulnerable to age-related declines. In previous studies, cognition has typically been measured using traditional paper-and-pencil tests; however, these tests can be quite complex and recruit many different abilities. We wanted to use a simpler test to assess processing speed in the hopes of tapping into the more basic abilities that underlie performance on more complex cognitive tasks. For this study, we chose a measure of visual processing speed called critical flicker fusion, or CFF. We tested how well CFF could predict cognition in both younger and older adults.
Medical Research: What are the main findings?
Response: As expected, younger adults had better visual processing speed than older adults. Interestingly, in both age groups, CFF significantly predicted performance on a test of executive functioning, which assess abilities such as problem-solving and shifting attention between different tasks.

MedicalResearch.com Interview with:
N.J. Scheers, PhD
Former manager of CPSC's Infant Suffocation Project
BDS Data Analytics, Alexandria, VA
Medical Research: What is the background for this study? What are the main findings?
Dr. Scheers: There are no federal regulations for crib bumpers. The American Academy of Pediatrics, the Canadian Pediatric Society, the National Institutes of Health, and others have long recommended against crib bumper use. Crib bumper manufacturers have a long-standing voluntary safety standard aimed at making crib bumpers safe. Neither of these approaches has worked to prevent deaths from bumpers.
Medical Research: What are the main findings?
Dr. Scheers: Using data from the Consumer Product Safety Commission (CPSC), the research identified 48 deaths from crib bumpers from 1985-2012. Reports of the deaths increased significantly and were three times higher from 2006 through 2012 than in previous years.
In most of the deaths, the crib bumpers were the only source of suffocation, rebutting beliefs that other items in the cribs (comforters, pillows, blankets) caused the deaths. In other deaths, wedging occurred between the bumper and other objects such as pillows and infant recliners. All of these deaths would have been preventable if crib bumpers had not been in the cribs.
The study linked more deaths to crib bumpers than the 48 indicated in the CPSC data. A review of data from the National Center for the Review and Prevention of Child Deaths reveals reports of 32 bumper-related deaths from 37 states from 2008-2011. That puts the number of fatalities tied to crib bumpers at 77 and suggests the actual number is much higher.
The study identified 146 injuries from 1990-2012. Eleven were “near-misses” in which the babies were rescued before they died. These were near-suffocations, chokings, strangulations, and falls from infants using bumpers to climb out of the cribs. There were reports of poor bumper design, such as a lack of bottom bumper ties, or construction problems, such as bumper ties and decoration that detached.
Parents often buy bumpers to prevent slat entrapments or to prevent infants bumping their heads in the cribs. This is the first study to show that these events occurred even with a bumper present.

Dr. Mistry: This study, conducted by researchers at the Agency for Healthcare Research and Quality (AHRQ), was seeking to explore what impact the Affordable Care Act (ACA) may have on the nation’s well-documented racial/ethnic disparities in insurance coverage, access to medical care, and preventive services utilization. We used pre-ACA (2005-2010) household data from AHRQ’s Medical Expenditure Panel Survey to examine patterns of coverage, access, and utilization, by race/ethnicity, for nonelderly adults who are targeted by ACA coverage expansion provisions.

MedicalResearch.com Interview with:
William G. Shadel, PhD
Associate Director, Population Health Program

RAND Corporation
Pittsburgh, PA 15213
Medical Research: What is the background for this study? What are the main findings?
Dr. Shadel: The tobacco industry spends almost all of its multi-billion dollar advertising budget at retail point-of-sale locations. A key feature of their advertising strategy includes the tobacco power wall, a prominent behind the cashier display of hundreds of cigarette and tobacco product brands. The power wall also displays posters for those tobacco products as well as pricing information. As such, it conveys a lot of positive messages about tobacco products to consumers.
The purpose of this experiment was to evaluate whether hiding or moving the tobacco power wall from its highly conspicuous location reduced teens’ smoking risk when they shop at convenience stores. The study took place in the RAND StoreLab (RSL), a life-sized replica of a convenience store that was constructed to explore a range of options for regulating tobacco products at point-of-sale retail locations. A sample of 271 teens (ages 11-17) was randomized to one of three experimental conditions: cashier (the tobacco power wall was located in its usual location, behind the cashier); side wall (the tobacco power wall was moved from behind the cashier to an out of the way location in the RSL); and hidden (the tobacco power wall was located behind the cashier, but was hidden behind an opaque wall). After teens finished shopping in the RSL, they completed questionnaires that measured their susceptibility to future smoking.
Teens assigned to the condition where the power wall was hidden were significantly less likely to report that they would smoke in the future, compared with those that were assigned to the cashier condition. Locating the power wall to a sidewall had no effect on smoking susceptibility.
