MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Using data from the Youth Risk Behavior Surveys for the period 1993-2017, we explore the effect medical and recreational marijuana laws have on teen use.

We find that medical marijuana laws (MMLs) are not associated with teen marijuana consumption, but recreational marijuana laws (RMLs) are actually negatively associated with teen use.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Although postoperative opioid prescribing has decreased in recent years due to an increased awareness of the risks of excess opioid prescribing, many patients are still prescribed more opioids than they need after surgery. In the pediatric population, most opioids are prescribed after surgical and dental procedures.

Although patients are often prescribed more opioids than they need after surgery, previous studies have found that excess opioids left unused after surgery are rarely properly disposed. These leftover opioids can be misused or accidentally ingested by young children. Previous studies have targeted the problem of non-disposal of opioids leftover after surgery by providing patients and families with educational materials describing proper methods of postoperative opioid disposal. However, these studies have had mixed results with some finding an increase in opioid disposal after education and others finding no effect of such education. In addition to education, another means of facilitating postoperative opioid disposal is the provision of drug disposal products. These products contain compounds that irreversible adsorb or oxidize medications, enabling them to be safely disposed of in the home garbage.

MedicalResearch.com: What is the background for this study?

Response: Minimizing care that provides little benefit to patients has become an important focus to decrease health care costs and improve the quality of care delivery.  Diagnostic imaging in children is a common focus for campaigns designed to reduce overuse both in Canada and the US. There are some suggestions that there may be more overuse of care in the United States than Canada, but there has been little study in children.

We compared the use of low-value diagnostic imaging rates from four pediatric emergency departments in Ontario to 26 in the United States from 2006 to 2016.  We defined low-value imaging as situations where children are discharged from an emergency department with a diagnosis for which routine use of diagnostic imaging may not be necessary, like asthma or constipation.  Continue reading

Team Sports Benefits Teens With a Troubled Childhood

MedicalResearch.com Interview with:
Molly C. Easterlin, MD

Fellow, UCLA National Clinician Scholars Program
Clinical Instructor, Pediatrics, Cedars-Sinai Medical Center 

MedicalResearch.com: What is the background for this study?

Response: Adverse childhood experiences or ACEs (including physical or emotional neglect or abuse, sexual abuse, domestic abuse, exposure to household substance misuse or mental illness, parental separation or divorce, and parental incarceration) are common with about half of children experiencing 1 and one-quarter of children experiencing 2 or more.

Children exposed to adverse childhood experiences have worse mental health throughout life, including higher rates of depression and anxiety. However, little is known about what factors improve long-term mental health in those exposed to ACEs. Additionally, as far as we are aware, no studies have looked at team sports participation as a potential factor that may be associated with improved mental health among those with adverse childhood experiences.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response:  Although e-cigarette aerosols are commonly perceived to be “harmless water vapors” they contain numerous potentially harmful chemicals including volatile organic compounds like formaldehyde, nicotine, heavy metals, and ultrafine particulates. Non-users can be exposed to these chemicals through secondhand exposure.

We found that in the US 4.9% of adults who lived in a household with children were current e-cigarette users. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Most high-income countries now use acellular pertussis vaccines (called DTaP, which are sub-unit vaccines based on purified antigens of the bacterium Bordetella pertussis) to protect children against pertussis. Although clinical trials demonstrated the short-term effectiveness of DTaP vaccines, there was a growing concern that the duration of protection they conferred was not very long. Those concerns were mostly based on the results of a number of epidemiological studies, which showed that the relative risk of contracting pertussis increased substantially over time, typically by 20–40% every year since last vaccination.

Although such increases seem high, it was not immediately obvious how to interpret them—the more so because pertussis epidemiology is complex.

In our study, we developed mathematical models of pertussis epidemiology to try to understand what the results of recent epidemiological studies really meant about the effectiveness and the duration of protection of DTaP vaccines. The most interesting—and perhaps counterintuitive—finding of our study was that those results are fully consistent with highly effective DTaP vaccines, which confer long-term protection. This is a consequence of the fact that pertussis is highly contagious and that the immunity conferred by DTaP, though very high, is not perfect.    Continue reading

Kids Who Don’t Drink Water, More Likely To Drink Sugar-Sweetened Beverages

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Sugar-sweetened beverage consumption has been linked to many negative health conditions, such as weight gain, dental caries, and type 2 diabetes. Previous research found that when you replace sugar-sweetened beverages (SSBs) with water intake then total energy intake goes down. We wanted to know how many calories from SSBs children consume when they drink water or not since sugar-sweetened beverages are often used as a replacement for water. SSB intake has been falling among children over the last 15 years, but there are still pockets and sub-populations that have high consumption levels. It is critical to identify which kids are particularly at risk for high SSB intake since this can lead to these negative health effects.

Overall we found that kids that did not consume any plain water (from tap or bottled water) consumed almost twice as many calories and percent of total calories from sugar-sweetened beverages than kids that consumed water. And for the sample overall that translated to nearly 100 extra calories on a given day.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Since IVF has become commonplace in the last three decades there has been concern about its potential for affecting the health of children conceived this way.  We know, for instance, that pregnancies enabled by IVF have more difficulties, and there are more birth defects among offspring.  So for this study we wished to see if children conceived by IVF have a different risk of childhoood cancer.

MedicalResearch.com: What should readers take away from your report?

Response: There is not an increased risk of most childhood cancers among children conceived by IVF.  A class of especially rare childhood cancers known as embryonal tumors, especially embryonal liver tumors, appeared slightly more likely among children conceived by IVF.   For these few cancers, even among children conceived by IVF, they remained very rare.  Overall these results should be reassuring to parents who have used IVF. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work? 

Response: For the few, rare cancers that seemed to be associated with IVF it would be helpful to see if these childrens’ tumors differ from other childrens’ tumors.  It will also be necessary to continue to follow cohorts of children conceived by IVF to see if their cancer experience differs at older ages.

MedicalResearch.com: Is there anything else you would like to add?

Response: This research took the cooperation of the Society for Assisted Reproductive Technology and over a dozen state departments of health over many years, for which we are thankful.  No disclosures.

MedicalResearch.com: What is the background for this study?

Response: In the highly sensitive context of prenatal diagnosis where autonomous and informed decision-making is of crucial issue, the present study is a companion study to a prospective clinical trial [ClinicalTrials.gov Identifier: NCT02127515] aiming at comparing clinical benefits involved by invasive vs. non-invasive testing in women at high risk of Down syndrome following routine combined screening.

Our study (involving 2,436 consecutive high-risk pregnant women following combined screening for Down syndrome) confirmed that attitudes towards invasive testing are notably guided by risk aversion to invasive testing-related fetal loss whereas it showed that attitudes towards non-invasive testing are notably guided by aversion to the ambiguity generated by results restricted to the only targeted abnormalities.

MedicalResearch.com: What did we already know about the potential for apps and wearables to help kids with autism improve their social skills, and how do the current study findings add to our understanding? What’s new/surprising here and why does it matter for children and families? 

Response: We have clinically tested apps/AI for diagnosis (e.g.  https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002705) in a number of studies.

This RCT is a third phase of a phased approach to establish feasibility and engagement through in-lab and at-home codesign with families with children with autism. This stepwise process is quite important to bring a wearable form of therapy running AI into the homes in a way that is clinically effective.

What’s new here, aside from being a first in the field, is the rigorous statistical approach we take with an intent-to-treat style of analysis. This approach ensures that the effect of the changes are adjusted to ensure that any significance observed is due to the treatment.  Thus, with this, it is surprising and encouraging to see an effect on the VABS socialization sub-scale. This supports the hypothesis that the intervention has a true treatment effect and increases the social acuity of the child.

With it being a home format for intervention that can operate with or without a clinical practitioner, it increases options and can help bridge gaps in access to care, such as when on waiting lists or if the care process is inconsistent.   Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: It is unclear if there is an association between type 1 diabetes and school performance in children. Some studies have found type 1 diabetes to be associated with worse performance, while others have found no differences. However, most of the existing literature are based on smaller, non-random samples of children with diabetes. In this study we used data on all public school children in the country of Denmark, involving more than 600,000 schoolchildren where approximately 2,000 had a confirmed diagnosis of type 1 diabetes. The children were tested in math and reading using a nationally standardized testing procedure, and we found no difference in the obtain test scores between children with diabetes compared to children without diabetes.  Continue reading

MedicalResearch.com: What is the background for this study?

Response: Before rotavirus vaccines were available, rotavirus infection was the most common cause of severe gastroenteritis in infants and young children. Because it is so contagious, infection in childhood is thought to be universal in unvaccinated children.

Previous studies indicated that rotavirus infection of infants might be an environmental promoter of type 1 diabetes. Therefore, we anticipated that the introduction of the rotavirus vaccine might alter the disease incidence in young children.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Pediatric solid organ transplant recipients are at increased risk for vaccine preventable infections due to life-long immunosuppressive medications.  The objectives of this study were to 1) evaluate in pediatric    solid organ transplant recipients the number of hospitalizations for vaccine-preventable infections in the first five years post-transplantation and 2) determine the associated morbidity, mortality and costs.

In this multicenter cohort study of 6980 children who underwent solid organ transplantation from January 1, 2004, to December 31, 2011, at a center participating in Pediatric Health Information System (PHIS), 15% of individuals had at least 1 hospitalization for a vaccine-preventable infection in the first 5 years after transplant.  Children who received transplants when they were younger than 2 years and recipients of lung, intestine, heart, and multi-visceral organs were at increased risk for hospitalization with a vaccine-preventable infection.  Transplant hospitalizations complicated by a vaccine-preventable infection were $120,498 more expensive (median cost) and were on average 39 days longer than transplant hospitalizations not complicated by vaccine-preventable infections Continue reading

MedicalResearch.com: What is the background for this study?

Response: Group B Streptococcus (GBS) is a leading cause of serious illness such as meningitis and sepsis in infants. Among infants, there are two main types of GBS disease. Early-onset GBS disease occurs during the first week of life and late-onset GBS disease occurs from the first week through three months of life. Rates of early-onset disease in the United States have decreased significantly since the 1990s through widespread implementation of intrapartum antibiotic prophylaxis (IAP) guidelines. However, IAP does not prevent late-onset disease. Maternal immunization represents a nonantibiotic strategy to prevent both early and late-onset disease. Multivalent polysaccharide-protein conjugate vaccines are under development against GBS capsular types, with candidate vaccines in phase I and II trials.

Active Bacterial Core surveillance (ABCs) conducts active surveillance for early and late-onset GBS disease among infants in select counties of 10 states, covering about 10% of live births across the United States. We analyzed data from early and late-onset GBS cases identified from ABCs between 2006 and 2015 to describe their epidemiology, incidence trends, and associated strain characteristics.

Dr. Ingunn Olea Lund

MedicalResearch.com: What is the background for this study?

Response: There are significant amounts of research on children of parents with alcohol use disorders – where the children are shown to be at risk of several adverse outcomes, including mental disorders, substance use disorders, suicide, impaired school performance, and employment problems. There is very little previous research on how other, more normal levels of parental drinking may influence child outcomes, such as mental health. This is a grave oversight, as there are vastly more parents with normal drinking patterns than there are parents who suffer from an alcohol use disorder. This means that there are potentially a lot more cases of adverse effect for children, and the number of children at risk may be higher than previously assumed.

In addition to parents’ alcohol use, several other risk factors in the family that may affect child mental health outcomes, such as parents’ mental health and socio-economic status. Researchers have tended to look at these risk factors separately, but as these risks tend to co-occur, it may be more informative to consider them together.

To our knowledge, this is the first study that examines possible harm from normal levels of parental drinking, alone or in combination with other parental risk factors, on children’s anxiety and depression.

The sample consists of more than 8700 triads: children and both their parents. We combined information from three health registries with survey data where both adolescents and their parents provided information about health and social conditions. The health registers include information about the children ‘s actual contact with the health care system; we used information about whether children received diagnoses and/or treatment for anxiety and/or depression.

MedicalResearch.com: What is the background for this study?

Response: The 2009 Family Smoking Prevention and Tobacco Control Act (FSPTCA) banned cigarettes with characterizing flavors (e.g., candy, fruit, clove) except menthol. However, there are no restrictions on the marketing and sales of flavored non-cigarette tobacco products. This has led to a proliferation of flavored tobacco products in the marketplace. Flavoring has become one of the leading reasons for current tobacco use among youth. It is reported that 81% of e-cigarette users, 79% of hookah users, 74% of cigar users, 69% of smokeless tobacco users, and 67% of snus users attributed the availability of appealing flavors for their tobacco use in 2013–2014 among teenagers aged 12 to 17 years. In November 2018, the FDA proposed new restrictions on flavored tobacco products.

No Detectable Developmental Issues in Children Exposed to Anesthesia and Surgery

Department of Anesthesia and Pain Medicine,
Child Health Evaluative Sciences
The Hospital for Sick Children
Department of Anesthesia, University of Toronto
Toronto, Ontario, Canada

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There is substantial evidence from laboratory studies that the developing brain is susceptible to injury from general anesthetic drugs, which culminated in the US Food Drug Administration issuing a safety communication in 2017 stating that the use of general anaesthetic drugs “for lengthy periods of time or over multiple surgeries or procedures may negatively affect brain development in children younger than 3 years”. Considering the substantial number of children who require general anesthesia every year (almost 3 million in the US annually) even small differences in child development outcomes after surgical procedures that require general anesthesia may have significant public health implications.

Undertaking studies of anesthesia-related neurotoxicity in humans is difficult as adverse child development is a function of the complex interaction between many risk and protective factors. By examining differences between biological siblings in Ontario, Canada, this study seeks to mitigate differences in risk from biological vulnerability and environmental factors, to provide a more accurate estimate of the adverse effects of anesthesia and surgery on child development.

In the current study, young children who had surgical procedures that require general anesthesia were not found to be at increased risk of adverse child development outcomes compared to their biological siblings who did not have surgery. These findings further support that exposure to anesthesia and surgery in early childhood is not associated with detectable adverse child development outcomes. Continue reading

Prenatal Exposure to Phthalates Linked to Language Delay in Preschool Children

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Phthalates have been known for long time as potential endocrine disrupters. Exposure for these kind of compounds during pregnancy have been associated to impacted sexual development, most often seen in boys. However, there is also findings showing that prenatal exposure for phthalates can be associated to neurodevelopment in offspring children.

This study is focusing on prenatal exposure for phthalates and language delay at 30-37 months of age and were conducted in Sweden (the SELMA study including 963 children) and the U.S. (the TIDES study including 370 children) with the same design, measurements and protocols.

In these two independent studies, prenatal exposure for two phthalates (DBP and BBzP) was associated to language delay in pre-school children. Unique things with this study is that we are measuring the exposure during early pregnancy (1st trimester), the size of the study, and that we examined it in two independent populations, one in Europe and one in the U.S. with similar results. 

MedicalResearch.com: What should readers take away from your report?

 Response: These compounds identified in this study are banned in many products, but since many of these (e.g., older vinyl flooring, electric cables, toys, etc.) have long life length, they can exposure people for several decades. From a consumers point of view it is good to try to find information on ingredients in these kind of products, but that can be difficult. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work? 

Response: We need other kind of more experimental studies that can tell us the biological mechanisms behind these effects.

MedicalResearch.com: What is the background for this study?

Response: We were interested whether high school students who tended to sleep less than 8 hours per night reported more risk-taking behaviors compared to high school students who slept at least 8 hours per night on a school night. We utilized a nationally representative dataset from the CDC of surveys that were completed by high school students between 2007 and 2015. Over that time, approximately 67,000 students were surveyed. Students were asked about the hours of sleep that they obtained on an average school night. They were also asked how often, in the month prior to the survey, they engaged in a number of risk-taking behaviors. Some behaviors were related to driving, like driving without a seatbelt or driving drunk, while others were related to using alcohol, doing drugs, or being involved in a fight. They were also asked about their mood, including whether they felt sad or hopeless, considered suicide, and whether they had attempted suicide.
