MedicalResearch.com Interview with: Aparna Raghuram, OD, PhD Optometrist, Department of Ophthalmology Instructor, Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Developmental dyslexia is a specific learning disability of neurobiological origin whose core cognitive deficit is widely believed to involve language (phonological) processing. Although reading is also a visual task, the potential role of vision has been controversial, and experts have historically dismissed claims that visual processing might contribute meaningfully to the deficits seen in developmental dyslexia. Nevertheless, behavioral optometrists have for decades offered vision therapy on the premise that correcting peripheral visual deficits will facilitate reading. Yet there is a surprising dearth of controlled studies documenting that such deficits are more common in children with developmental dyslexia, much less whether treating them could improve reading. In the present study, we simply assessed the prevalence and nature of visual deficits in 29 school aged children with developmental dyslexia compared to 33 typically developing readers. We found that deficits in accommodation 6 times more frequent in the children with developmental dyslexia and deficits in ocular motor tracking were 4 times more frequent. In all, more than three-quarters of the children with developmental dyslexia had a deficit in one or more domain of visual function domain compared to only one third of the typically reading group.

MedicalResearch.com Interview with: Julie L. Hudson, PhD Center for Financing, Access, and Cost Trends Agency for Healthcare Research and Quality Rockville, Maryland MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Since 2013, public coverage has increased not only among low-income adults newly eligible for Medicaid but also among children and adults who were previously eligible for Medicaid or the Children’s Health Insurance Program (CHIP). Recent research has shown that growth in public coverage varied by state-level policy choices. In this paper we study the growth in public coverage (Medicaid/CHIP) for three population samples living in Medicaid Expansion states between 2013 and 2015: previously eligible children, previously eligible parents, and newly eligible parents by state-level marketplace policies (Note: eligibility refers to eligible for Medicaid/CHIP, eligibility for marketplace subsidized coverage). All marketplaces are required to assess each applicants’ eligibility for both the marketplace and for Medicaid/CHIP. States running state-based marketplaces are required to enroll Medicaid-/CHIP-eligible applicants directly into public coverage (Medicaid or CHIP), but states using federally-facilitated marketplaces can opt to require their marketplace to forward these cases to state Medicaid/CHIP authorities for final eligibility determination and enrollment. We study the impact of marketplace policies on public coverage by observing changes in the probability Medicaid-/CHIP-eligible children and parents are enrolled in public coverage across three marketplace structures: state-based marketplaces that are required to enroll Medicaid-/CHIP-eligible applicants directly into public coverage, federally-facilitated marketplaces in states that enroll Medicaid-/CHIP-eligible applicants directly into public coverage, and federally-facilitated marketplaces with no authority to enroll Medicaid-/CHIP-eligible applicants into public coverage. Supporting the existing literature, we find that public coverage grew between 2013-2015 for all three of our samples of Medicaid-/CHIP-eligible children and parents living in Medicaid expansion states. However, we show that growth in public coverage was smallest in expansion states that adopted a federally-facilitated marketplace and gave no authority to the marketplace to enroll Medicaid-/CHIP-eligible applicants directly into public coverage. Additionally, once we account for enrollment authority, we found no differences in growth of public coverage for eligible children and parents living in expansion states that adopted a state-based marketplace versus those in states that adopted a federally-facilitated marketplaces with the authority to directly enroll Medicaid-/CHIP-eligible applicants (more…)

MedicalResearch.com Interview with: Dr. Tessie W. October. MD, MPH Critical Care Specialist Children’s National Health System  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This is a qualitative study that examines the impact of empathetic statements made by doctors on the ensuing conversation with families of critically ill children. We know families are more satisfied when doctors show empathy, but until this study, we did not know how these empathetic statements are received by families. In this study we found that doctors frequently respond to a family’s emotions by responding with empathy, but how the doctor presented that empathetic statement mattered. When doctors made an empathetic statement, then paused to allow time for a family’s response, the family was 18 times more likely to share additional information about their fears, hopes or values. Conversely, when doctors buried the empathetic statement within medical talk or if a second doctor interrupted, the empathetic statement frequently went unheard by the family. (more…)

MedicalResearch.com Interview with: Andrew N. Meltzoff Ph.D. Job and Gertrud Tamaki Endowed Chair Co-Director, Institute for Learning & Brain Sciences (I-LABS) Professor of Psychology Elected member of the American Academy of Arts & Sciences. University of Washington, Box 357920 Seattle, WA 98195 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We are applying safe, noninvasive neuroscience techniques to examine the development of young children. We are especially interested in social-emotional learning and cognitive development. The way the body is represented in the brain is well-studied topic in cognitive neuroscience using adults, for example, the classical studies by W. Penfield on the ‘sensorimotor homunculus’ in the adult brain. The development of neural body map in human infants is, however, deeply understudied. We think that the way the body is represented in the brain will provide important information about infant learning prior to language. For example, one of the chief avenues of learning in human infants is through observation and imitation. Infants watch what adults do and imitate those behaviors, rapidly learning about people, things, and causal relations. The mechanisms of imitation themselves are interesting. In order to imitate, infants need to know what part of their body to move and how to move it. We wanted to explore the representations of the human body in the infant brain prior to language. (more…)
Author Interviews, Pediatrics, Smoking, Tobacco, Tobacco Research, University Texas / 10.07.2018

MedicalResearch.com Interview with: “hookah” by Ksenia M is licensed under CC BY 2.0Cheryl L. Perry, Ph.D. Professor of Health Promotion and Behavioral Sciences The Rockwell Distinguished Chair in Society and Health University of Texas Health Science Center at Houston (UTHealth) School of Public Health, Austin, Texas MedicalResearch.com: What is the background for this study? What are the main findings? Response: There have been large changes in the social environment over the past 10 years that have affected tobacco use among youth and young adults. These include social media, e-cigarettes, and new regulations aimed at preventing use among youth. Historically, nearly all onset of tobacco use, particularly cigarettes, occurred prior to high school graduation by age 18. Some recent national cross-sectional data suggested that onset might be occurring among young adults. We decided to explore, with national and Texas data, whether onset of tobacco use was more likely to occur among young adults. We did this by analyzing data from 3 studies over one year. (more…)

MedicalResearch.com Interview with: Alison J. Culyba, MD, PhD, MPH Assistant Professor of Pediatrics UPMC Children’s Hospital of Pittsburgh University of Pittsburgh School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Homicide is the third leading cause of death among adolescents, and disproportionately affects minority youth in under-resourced urban communities. Most research on youth violence focuses on risk factors, such as weapon carrying and substance abuse. We know much less about factors that protect youth from violence. Future orientation, defined as hopes and plans for the future, is linked to many important positive outcomes for youth, including doing well in school and avoiding illicit substances. However, there has been very little research to examine whether future orientation may also protect youth from violence. To study links between future orientation and violence perpetration, we surveyed over 850 male youth in lower resource neighborhoods in Pittsburgh as part of a community-based sexual violence prevention study. We found that youth with positive future orientation were significantly less likely to report threatening someone with a weapon or injuring someone with a weapon in the past nine months. (more…)

MedicalResearch.com Interview with: Jon-Patrick Allem, Ph.D., M.A. Research Scientist Keck School of Medicine of USC MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by JUUL?  Response: The JUUL vaporizer is the latest advancement in electronic cigarette technology, delivering nicotine to the user from a device about the size and shape of a thumb drive. JUUL has taken the electronic cigarette market by storm experiencing a year-over-year growth of about 700 percent. In our most recent study, we wanted to document and describe the public’s initial experiences with JUUL. We collected posts to Twitter containing the term “Juul” from April 1, 2017 to December 14, 2017. We analyzed over 80,000 posts representing tweets from 52,098 unique users during this period and used text classifiers (automated processes that find specified words and phrases) to identify topics in posts.

MedicalResearch.com Interview with: “Bikes” by Britta Frahm is licensed under CC BY 2.0Lara McKenzie, PhD Principal investigator in the Center for Injury Research and Polic Nationwide Children’s Hospital. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Bicycling is a great way for families to get outside and be active together, but certain precautions need to be taken to keep everyone safer. This study looked at bicycle-related injuries among children age 5-17 years treated in hospital emergency departments in the United States from 2006 through 2015 and found that, despite a decrease in the rate of injuries over the 10-year study period, there were still more than 2.2 million injuries. This averages 608 cases per day or 25 every hour. The majority of injuries involved children 10 to 14 years of age (46%) and boys (72%). The most commonly injured body region was the upper extremities (36%), followed by the lower extremities (25%), face (15%), and head and neck (15%). The most common types of injury were bruises and scrapes (29%) and cuts (23%). Overall, traumatic brain injuries (TBIs) represented 11% of total injuries and were most common among patients 10-14 years of age (44%). About 4% of patients were hospitalized. Injuries most frequently occurred in the street (48%) or at home (37%). Helmet use at the time of injury was associated with a lower likelihood of head and neck injuries and hospitalizations, but there was no significant change in the rate of injury among helmet users over the study period. Motor vehicle involvement increased the odds of bicycle-related TBIs and injury-related hospitalizations.  (more…)

MedicalResearch.com Interview with: Gary A. Smith, MD, DrPH Director, Center for Injury Research and Policy Nationwide Children’s Hospital Columbus, OH MedicalResearch.com: What is the background for this study? Response: Buprenorphine is a prescription opioid medication commonly used to treat opioid use disorder. From 2005 to 2010, the annual number of individual patients who received a buprenorphine prescription increased from 100,000 to more than 800,000. Although buprenorphine is important for the treatment of opioid use disorder, pediatric exposure to this medication can result in serious adverse outcomes.

MedicalResearch.com Interview with: Melissa Lorenzo MD Pediatric medical resident Dr. Lorenzo is currently training at the University of Toronto, however the research was conducted while a medical student at Queens University MedicalResearch.com: What is the background for this study? Response: Preterm infants are born before 37 weeks gestation, with late preterm neonates defined as infants born between 34 weeks to 37 weeks gestation. Of all preterm births, over 70% of babies are born in the late preterm period. Late preterm births are common, affecting 12.5% of all births in the United States. Compared to infants born at term, late preterm neonates are at increased risk for many common complications following birth such as jaundice, low blood sugar, and respiratory distress, prolong hospital stay, admission to the neonatal intensive care unit, and increase readmission rate after hospital discharge. There are many causes for preterm delivery- two important ones are early onset of labour either spontaneous or after premature rupture of membranes, and medically indicated delivery prior to full term gestation due to chronic diseases in mother affecting her health in pregnancy, fetal medical reasons, or placental insufficiency. There is a debate that the risk of neonatal complications is affected by the causes of preterm delivery with immaturity acting as a contributing factor. The relative contribution of immaturity versus the reason for delivery and the resulting neonatal complications is unclear. (more…)

MedicalResearch.com Interview with: Cheryl Rosenfeld PhD DVS Professor of biomedical sciences in the College of Veterinary Medicine investigator in the Bond Life Sciences Center, and research faculty member for the Thompson Center for Autism and Neurobehavioral Disorders University of Missouri MedicalResearch.com: What is the background for this study? What are the main findings? Response: My laboratory has been examining the effects of developmental exposure to the endocrine disrupting chemical (EDC), bisphenol A (BPA) on later neurobehavioral responses in a variety of rodent models, including California mice. This species is unique in that both parents rear the pups and they have monogamous social structure, similar to most human societies. We had previously found that developmental exposure to BPA or another EDC, ethinyl estradiol (EE), disrupted later maternal and paternal care by F1 offspringto their F2 pups. Rodent pups use vocalizations both in the range of human hearing (20,000 hertz or below) and outside of the range of human hearing (20,000 hertz) to communicate with each other and their parents, and for the latter, such communications serve as a trigger to provide additional parental care in the form of nutrition or warmth to the pups. Thus, in the current studies we sought to determine if exposure of the grandparents to BPA or EE could lead to disruptions in their grandoffspring (F2 generation) pup communications that might then at least partially account for the parental neglect of their F1 parents. We found that early on female BPA pups took longer to call to their parents but later during the neonatal period they vocalized more than pups whose grandparents were not exposed to either chemical. Such vocalization changes could be due to multigenerational exposure to BPA and/or indicate that the pups are perceiving and responding to the reduced parental care and attempting but failing to signal to their F1 parents that they need more attention.

MedicalResearch.com Interview with: Kris R. Jatana, MD, FAAP, FACS Associate Professor Director, Pediatric Otolaryngology Quality Improvement Department of Otolaryngology-Head & Neck Surgery Nationwide Children's Hospital & Wexner Medical Center at Ohio State University MedicalResearch.com: What is the background for this study?   Response: More than 2,500 pediatric button battery ingestions occur annually in the United States. When lodged in the esophagus, rapid injury can occur from the tissue and saliva connecting the circuit of the battery. Serious injury can occur in a matter of hours. This results in a highly alkaline caustic injury that dissolves tissue, a process called liquefactive necrosis. There was a need for novel mitigation strategies to slow the progression of esophageal injury caused by presence of a button battery. This study aimed at identifying a palatable liquid that can be given at home or hospital setting to reduce esophageal injury until the battery can be removed. (more…)

MedicalResearch.com Interview with: Sylvia Becker-Dreps, MD MPH Associate Professor, Department of Family Medicine Associate Director, Office of International Activities (Latin America Focus) Director, UNC Program in Nicaragua University of North Carolina at Chapel Hill Chapel Hill, NC 27599-7595 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Pertussis (or whooping cough) is a respiratory infection caused by bacteria. It has been becoming more common in the US over the past two decades. Infants are more likely to be hospitalized and die of the disease. They are especially vulnerable in the first months of life because they have not yet had time to complete the DTaP vaccine series themselves. (Currently, infants receive 3 doses of DTaP at 2,4, and 6 months of age.) Immunizing mothers allows the mothers to pass antibodies against pertussis through the placenta and provide passive immunity to infants early in life. In early 2013, the CDC recommended that pregnant women receive a Tdap vaccine in every pregnancy. That recommendation was based on studies of the immune response to the vaccine, not real cases of pertussis. Our study examined clinical cases of pertussis in over 675,000 infants throughout the US. We found that in the first six months of life, infants of vaccinated mothers (those that received Tdap during pregnancy) had 75% less pertussis hospitalizations and 50% less pertussis cases overall.  (more…)

MedicalResearch.com Interview with: “Bart Infant” by Bart Everson is licensed under CC BY 2.0Gwen M. Westerling, BSN, RN, CIC Infection Preventionist Helen DeVos Children's Hospital MedicalResearch.com: What is the background for this study? Response: The setting of this study is a Level III Neonatal Intensive Care Unit (NICU) with 106 beds. In 2016, an increase in Hospital Acquired Infections (HAI) was noted in the Neonatal Intensive Care Unit (NICU) caused by Staphylococcus aureus (SA) through diligent Infection Prevention Surveillance. When we reviewed the literature we found the SA is a common skin colonizer and can be a problem for neonates with immature skin and immune systems. Staphylococcus aureus is easily transmitted through direct contact with skin, the contaminated hands of health care workers, the environment and equipment. We also found one study that listed skin to skin care as a risk factor for acquisition of SA. Before we saw the increase in infections some process changes occurred in our NICU that included increased skin to skin care, meaningful touch between neonates and parents, and two person staff care. We hypothesized that the process changes were exposing neonates to increased amounts of Staphylococcus aureus and contributing to the increase in infections. (more…)

What are the main findings? Response: We were interested in seeing whether the fine motor deficits typically seen in amblyopia (lazy eye) and strabismus (crossed eyes) translate to an academic setting. Namely, transferring answers to a multiple choice answer form widely used in standardized testing in schools. Children with amblyopia and strabismus took about 28% longer than their peers transferring answers to a multiple choice answer form, even though they have good vision in one or both eyes.  (more…)

MedicalResearch.com Interview with: “Driving” by Martin Alvarez Espinar is licensed under CC BY 2.0Kristina Elise Patrick, Ph.D Nationwide Children’s Hospital Columbus, OH 43205 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Many families of young adults with autism spectrum disorder (ASD) are concerned that they may have difficulty acquiring driver’s licenses and driving safely because of symptoms of ASD. However, the ability to drive opens the door to a variety of social, occupational, and educational experiences. We aimed to assess differences in simulated driving behaviors of young adults with ASD and those with typical development and to evaluate whether differences depended on level of driving experience and complexity of the driving task. On average, young adults with ASD had more difficulty regulating their speed and position within their lane compared with typically developing individuals even on a very basic rural route. After completing the basic route, drivers were required to engage in more complex tasks such as changing the radio or engaging in conversation while driving, driving through a construction zone, and following behind a truck. On complex driving tasks, drivers with ASD who had acquired licensure drove similarly to typically developing drivers who had acquired licensure. However, novice drivers with ASD had more difficulty than typically developing drivers regulating their speed and position within the lane. (more…)

MedicalResearch.com Interview with: “Blood Pressure” by Bernard Goldbach is licensed under CC BY 2.0Ali Khashan, PhD Senior Lecturer in Epidemiology School of Public Health & INFANT Centre University College Cork Cork, Ireland MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is some evidence to suggest an increased likelihood of neurodevelopmental disorders in relation to hypertensive disorders in pregnancy, however consensus is lacking. Considering hypertensive disorders in pregnancy are among the most common prenatal complication, we decided to synthesise the published literature on this topic by conducting a comprehensive systematic review and meta-analysis. Our main findings suggest that hypertensive disorders in pregnancy are associated with about 30% increase in the likelihood of autism spectrum disorders (ASD) and ADHD in the offspring, compared to offspring not exposed to hypertensive disorders in pregnancy.

MedicalResearch.com Interview with: Alfio Maggiolini, MD Minotauro, Milan MedicalResearch.com: What is the background for this study? What are the main findings? Response: Antisocial behaviour is common during adolescence and it incurs significant costs both for society and for the young people themselves. Persistent antisocial behaviour places a heavy burden on the community, the justice system and the public health system. Responses to juvenile crime have always seen a tension between a focus on the understanding and the rehabilitation of the youth and the need to enforce discipline and public safety through punishment and threat. The treatment of young offenders was traditionally deemed particularly difficult, and often ineffective. In recent years, therapeutic nihilism has given way to cautious optimism. While punitive-based approaches, at all levels, are hardly ever effective in the long term, the most popular and effective programs tend to focus on behaviour control. Common core elements of such programs include positive reinforcement, problem solving skills training and role playing, as behavioral problems are often assumed somewhat inherently wrong, or a “lack of something”, the programs aims at improving or changing. The study presents a developmental approach that understands behavioral problems as the result of intentions, values and goals that need to be taken in full consideration and that are usually legitimate, even though carried out in ways that prove dysfunctional for both the young person and society. In other words, we consider antisocial behaviors as maladaptive responses to legitimate developmental tasks, a deviant way of meeting positive goals and taking control of one’s life. In the program we describe, a developmental understanding is combined with a psychoanalytically informed perspective on treatment and delivered in multi-modal terms. It has been carried out in Italy for the past 20 years, with positive outcomes, both in private practice and within the juvenile justice services.  (more…)

MedicalResearch.com Interview with: “baby teeth” by Thomas Ricker is licensed under CC BY 2.0Christine Austin PhD Department of Environmental Medicine and Public Health Icahn School of Medicine at Mount Sinai New York, NY 10029 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Previous studies have shown that some metals (nutrients and toxicants) are absorbed and metabolized differently in children with autism spectrum disorder compared to neuro-typical children. However, it is not known when this dysregulation occurs and it is incredibly difficult to study prenatal metal metabolism. Teeth, which begin forming prenatally, grow by adding a new layer every day, much like the yearly growth rings in trees. Each layer formed captures many of the chemicals circulating in the body at the time. We have developed a method to measure metals in these layers to build a timeline of metal exposure during the prenatal and early childhood period. We found that the cycles of copper and zinc metabolism were disrupted in children with ASD and used this feature to develop a method to predict the emergence of autism spectrum disorder with 90% accuracy.

MedicalResearch.com Interview with: Michael S. Blaiss, MD, FACAAI Executive Medical Director American College of Allergy, Asthma & Immunology Arlington Heights, IL 60005 MedicalResearch.com: Is this research important? Why or why not? Response: There has not been a comprehensive review of how allergic rhinitis impacts the adolescent population. Most studies put adolescents in with children and yet we know that how disease affects adolescents may be dramatically different than children. Adolescents is a difficult enough time with a chronic condition MedicalResearch.com: What is the key take-home message? Response: The symptoms associated with nasal and eye allergies can be different in adolescents compared with adults and children and lead to poor quality of life and impair learning in school. Adolescents with AR/ARC may experience difficulties falling asleep, night waking, and snoring, and generally have poorer sleep. Therefore health care providers need to aggressively control the adolescent’s allergic rhinitis.  (more…)

MedicalResearch.com Interview with: “Great Grandmother” by David Amsler is licensed under CC BY 2.0Rebecca Somerville MB BCh BAO, BMedSci, MRCPI, MPH, PhD School of Public Health, Physiotherapy and Sports Science University College Dublin Dublin, Ireland  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Rates of obesity in the Western world have increased dramatically over recent decades. The negative health consequences of obesity are well known and significant amounts of research have been conducted into the causes and possible solutions. While it is clear that there have been massive changes in diet and physical activity at a societal level that are primarily responsible for this 'obesity epidemic', it is less clear the extent to which obesity, once established, or risk factors for same, can be perpetuated down generations. Family studies lend opportunity to explore these questions, however there are few world wide which incorporate 3 generations. We therefore sought to examine patterns of central adiposity, as measured by waist circumference, between grandparents and their grandchildren, separately in maternal and paternal lines. We were able to utilize prospectively collected data from the Lifeways Cross-Generation Cohort Study. This is a longitudinal birth cohort, established in Ireland in 2001, involving up to 7 members of the same family (mother, father, child and 4 grandparents). In the 589 families where a child had a waist circumference measurement we found that, at the age of both 5 and 9, there was a direct relationship between the waist circumference of the maternal grandmother and her grandchild (both male and female). This remained after adjustment for a wide range of confounding variables including mother's waist circumference. There was no relationship seen with any of the other grandparents. (more…)

MedicalResearch.com Interview with: Natalie Castellanos Ryan, PhD École de Psychoéducation Université de Montréal Outremont Canada  MedicalResearch.com: What is the background for this study? Response: Our study followed a group of boys living in low socioeconomic neighbourhoods in Montreal (N=1030) from early childhood to 28 years of age to investigate: 1) whether the age at which one starts to use cannabis across adolescence is associated with the risk of developing drug abuse by early adulthood, when one controls for  arrange of known risk factors for cannabis use and problems assessed across development (risk factors in childhood, adolescence and early adulthood); and 2) the developmental pathways from early risk factors to drug abuse problems. To examine these associations, the study collected  self-reported cannabis use information from these boys annually from ages 13 to 17 years and drug abuse symptoms at 28 years, as well as teacher, parent and child reported information on a number of environmental (family and friend) and child characteristics (e.g., impulsivity, delinquency, school performance) across childhood and adolescence. Alcohol and other drug use was also assessed across adolescence and early adulthood. (more…)
Author Interviews, Nutrition, Pediatrics / 18.05.2018

MedicalResearch.com Interview with: Katherine Ottolini MD, lead study author Children’s National Health System and Catherine Limperopoulos, Ph.D., senior study author and Director of Developing Brain Research Laboratory Children’s National Health System MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nutrition is an important modifiable factor for brain development in premature infants, however few studies have evaluated the impact of nutritional interventions in the neonatal intensive care unit (NICU) on structural brain development in very premature infants using advanced, quantitative MRI techniques. The goal of this study was to utilize quantitative MRI to evaluate the impact of macronutrient (carbohydrate, protein, fat) and energy intake throughout the duration of the NICU stay on brain volumes and white matter development in very premature infants at term-equivalent age (TEA). We prospectively enrolled 68 very low birthweight infants (< 1500g) admitted to Children’s NICU within the first 7 days of life. We found significant negative associations between cumulative macronutrient and energy intake on both the brain’s white matter microstructural development (in the superior cerebellar peduncle, corpus callosum) and regional brain volumetric growth (cortical gray matter and cerebellum). In contrast, when evaluating average nutritional intake, we found significant associations between lipid and energy intake and regional brain volumes in the cortical gray matter, brainstem and cerebellum.  (more…)

MedicalResearch.com Interview with: Dr Sharon Wheeler PhD Lecturer in Sport, Physical Activity and Health Department of Sport and Physical Activity Faculty of Arts and Sciences Edge Hill University Lancashire MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is well-known that family background and parents’ investment in their children has a big impact on a number of outcomes, including how well people do at school, the jobs they get, and how they spend their leisure time. It is also known that it is middle-class parents who tend to work particularly hard to make sure their children get on in life. This research starts to question whether parents’ investment in their children’s organised activities is having the desired impact. Parents initiate and facilitate their children’s participation in organised activities as it shows that they are a ‘good’ parent and they hope such activities will benefit their children in both short-term (keeping fit and healthy, developing friendship groups) and long-term ways (getting jobs, having lots of opportunities in the future). The reality, which has been highlighted in this research, is that while children might experience some of these benefits, a busy organised activity schedule can put considerable strain on parents’ resources and families’ relationships, as well as potentially harm children’s development and well-being.

Response: We have been studying the steady increase in gun violence that has been occurring in popular PG-13 movies since the new rating was adopted in 1984.  It has recently even surpassed the amount of gun violence in R-rated movies.  Since these movies are open to the public at any age, we are concerned that they promote the use of guns and potentially socialize youth to believe that using guns to defend oneself is an appropriate way to handle threats and other conflicts. We knew that the rating requires the omission of graphic consequences, such as blood and suffering, that can make the violence more acceptable.  But we also wondered whether the motivation for the violence might make a difference as well.  Many of the characters in PG-13 movies are seen as heroic (e.g., Bruce Willis and Liam Neeson).  Could that also be a factor that makes such films more acceptable to parents despite their concerns about their children seeing so much violence in the movies.  So, we conducted this experiment to see if parents are less upset by justified violence in PG-13 style movies.  (more…)

MedicalResearch.com Interview with: Karen Fratantoni, M.D., M.P.H. Pediatrician and lead study author Children’s National Health System MedicalResearch.com: What is the background for this study? Response: We looked at the prevalence of depressive symptoms at NICU discharge and at six months after discharge among 125 parents randomized to the control group of a larger PCORI-funded trial of peer-to-peer support after NICU discharge. Determining factors associated with parental depressive symptoms at NICU discharge may help to identify at-risk parents who could benefit from mental health support.
