Caregiver Depressive Symptoms and Primary Medication Nonadherence in Children With Asthma.

The purpose of this study was to identify risk factors for primary medication nonadherence among low-income minority children with persistent asthma. Data were from an environmental control and educational intervention for children with uncontrolled asthma who were treated in the emergency department for an asthma exacerbation. Presence or absence of pharmacy records for child asthma medications was the outcome of interest. A range of sociodemographic, health, and psychosocial measures were included in the binary logistic regression. Of the 222 youths (mean age = 6.3 years; 93.7% Black), 25 (11.3%) lacked pharmacy records of asthma medications. For every 1-point increase in caregiver depressive symptoms, the odds of the child having a pharmacy record declined by 5% (odds ratio = 0.95; p = .012). Providers should systematically assess and monitor caregiver depressive symptoms as a potential contributing factor for primary medication nonadherence in low-income minority children with persistent, uncontrolled asthma.

Substance Use in Youth: What Could an Ounce of Prevention Be Worth?

* Abbreviations: CPSTF — : Community Preventive Services Task Force USPSTF — : US Preventive Services Task Force Risk for substance use disorders begins early in life. Approximately 65% of adults in treatment of opioid use disorder report that their first use occurred before the age of 251; for adult daily smokers, the estimate is 90%.2 As experimental use of substances transitions to regular use and problematic use, and ultimately to a use disorder, abstinence becomes increasingly difficult to achieve; many risks, including unintentional injury, damaged relationships, and even lasting alterations to a youth’s developing brain, have likely already occurred. For these reasons, preventing substance use among children, adolescents, and young adults is critical. For substance use prevention efforts to have meaningful population health impacts, clinical preventive services (typically defined as interventions deployed in health care settings that are used to either prevent illness or detect it in a more treatable stage) cannot be the sole, or even primary, pathway to improved population-level substance use outcomes. Such clinical services, even when evidence-based themselves, need to be deployed in the context of public health–minded communities and sound policy environments, with attention given to both the … Address correspondence to Caroline Kistin, MD, MSc, Division of General Pediatrics, Boston Medical Center, 801 Albany St, Boston, MA, 02119.

Early breast cancer screening in childhood cancer survivors treated with chest radiation may reduce deaths by more than 50.

The early initiation of annual breast cancer screening with magnetic resonance imaging (MRI) among survivors of childhood cancer who have been treated with chest radiation may reduce their breast cancer mortality risk by at least 50% according to a new study published in the Annals of Internal Medicine.1 Girls who receive chest radiation for childhood cancer are at increased risk for breast cancer. Indeed, research suggests that as many as 30% develop the disease by the age of 50 years. Nonetheless, there are various schools of thought regarding how and when to monitor for the disease in these survivors. In an effort to determine the best screening strategies for this population, investigators used modeling to compare the results of different strategies. Corresponding author Jennifer Yeh, PhD, an assistant professor of pediatrics at Harvard Medical School and an associate scientific researcher in the Division of General Pediatrics at Boston Children's Hospital, and colleagues across the country used 2 breast cancer simulation models that were developed to guide screening recommendations for non–breast cancer survivors. The models are part of the Cancer Intervention and Surveillance Modeling Network and were adapted with information from the Childhood Cancer Survivor Study, a cohort study following outcomes in more than 24,000 survivors of childhood and adolescent cancers. One study limitation was that the data came from childhood cancer survivors diagnosed between 1970 and 1986. Cancer treatment has evolved since then to incorporate decreased doses and improved delivery of radiation as well as digital mammography screening. Nonetheless, results show that early screening can save lives, Dr. Yeh says.

Laboratory results are notable for urinalysis with 20 to 40 white blood cell (WBC) count/high-power field and hemoglobin (Hb) of 10.7 g/dL (107 g/L; normocytic). She is discharged from the hospital on trimethoprim/sulfamethoxazole for presumed urinary tract infection. She returns on day 5 of illness with a maculopapular rash. Her laboratory results show a normocytic anemia, elevated transaminases, and pyuria. Urine culture obtained 2 days before is negative. She is hospitalized for presumed urinary tract infection. Repeat testing shows albumin of 3.0 g/dL (30 g/L), C-reactive protein of 217 mg/L (2,066 nmol/L; reference range, 0 to 7.5 mg/L), erythrocyte sedimentation rate of 71 mm/hour (reference range, 0 to 10 mm/hour). Blood and urine cultures remain negative. A chest radiograph demonstrates “early focal airspace disease.” She is started on azithromycin and discharged from the hospital with diagnoses of suspected viral illness and possible pneumonia.

The patient presents to another ED on day of illness 15 with continued daily fevers and is discharged from the hospital with diagnosis of bronchiolitis. On day 22 of illness, she develops facial asymmetry, prompting the ED physician to obtain an abdominal ultrasound, head computed tomography, chest radiograph, lumbar puncture, and laboratory studies showing a Hb of 7.1 g/dL (71 g/L), WBC count of 23,300/ μ L (23.3 × 109/L), platelets of 922,000/ μ L (922 × 109/L), albumin of 2.8 g/dL …

Medical Cannabinoid Products in Children and Adolescents.

1. Kathleen K. Miller, MD* 2. Jonathan D. Klein, MD, MPH† 1. *Division of General Pediatrics and Adolescent Health, Department of Pediatrics, University of Minnesota, Minneapolis, MN 2. †University of Illinois at Chicago, Chicago, IL Cannabinoid-containing products have become increasingly ubiquitous worldwide, both through legalization of recreational marijuana and widespread use of cannabinoid derivatives in medical products. In the United States, the Centers for Disease Control and Prevention (CDC) reported that more than 1 in 3 adolescents said they have tried recreational marijuana in 2017. Pediatricians should be aware of the limitations of cannabinoids as medical treatments, and should knowledgeably counsel patients about their potential risks and benefits. Cannabinoids are derived from the cannabis plant, which contains a variety of metabolically active compounds, of which the most well-known are tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is derived primarily from marijuana plants, and CBD primarily from hemp plants. THC is the primary psychoactive ingredient in marijuana and is responsible for the “high” associated with marijuana use. CBD, conversely, does not have psychoactive effects. In recent years, CBD has experienced a surge in popularity as an alternative treatment for a variety of ailments. Manufacturers have claimed that it has anxiolytic and anticonvulsant properties and that it can treat chronic pain, insomnia, and posttraumatic stress disorder. Recreational marijuana and plant derivatives of cannabis that can be smoked or ingested in edible forms contain THC in addition to other, less psychoactive cannabis-derived compounds. Only one cannabinoid derivative is Food and Drug Administration (FDA)–approved for use in children: dronabinol is approved for the treatment of nausea and vomiting induced by chemotherapy. Synthetic cannabinoids, also known as spice or K2, have neither therapeutic properties nor medical …

Sudden Unexplained Infant Deaths and Day of Life 0.

* Abbreviations: SIDS — : sudden infant death syndrome SUID — : sudden unexplained infant death Fifty years ago, an extraordinary group of pathologists, pediatricians, and epidemiologists met to address the limited research and numerous diagnoses applied to unexplained, largely sleep-related pediatric deaths. Their efforts led to the identification of a new category of disease, sudden infant death syndrome (SIDS). Among the observations fueling the creation of the category was the relative sparing of neonates despite what should be increased vulnerability in the early days of life. When Dr Bruce Beckwith, the conference’s leader, asked whether anyone doubted this age-related sparing, not a single objection was raised.1 Yet, humility about what was not yet known led to broader diagnostic criteria of “any infant or young child.” Years later, SIDS was redefined as pertaining to infants <1 year of age.2 Still later, when classification practices scattered because of objections about the concept of SIDS and the varied use of alternative terminologies, the composite of sudden unexplained infant death (SUID) came to stand in.3 In this issue of Pediatrics , big data concur with the pioneering thinkers and draw the demarcation at 1 week.

Food Insecurity During Early Childhood: Marker for Disparities in Healthy Growth and Development.

Food insecurity is an important social determinant of health,1 a key indicator of limited resources and material hardship,2,3 and a source of significant stress as parents and other caregivers seek to provide healthy child nutrition.4 As such, food insecurity would be expected to adversely affect child growth5,6 and health and development more broadly.7,8 However, there has been limited study of associations between food insecurity and child outcomes during the critical period of early childhood.9–11 The authors of “Food Insecurity, Health and Development in Children Under Age Four Years” aim to address this gap by using a large sample of families at high risk for both food insecurity and child health disparities.12 Contrary to the authors’ hypotheses, limited relations between food insecurity and child obesity or other growth parameters were found in the study. The only significant associations were for children between 25 and 36 months old, for whom household food insecurity was associated with increased adjusted odds of obesity. In contrast, no significant associations were found after adjustment for … Address correspondence to Rachel S.

Telemedicine and Antibiotic Use: One Click Forward or Two Steps Back?

* Abbreviations: DTC — : direct-to-consumer RTI — : respiratory tract infection The use of telehealth services in general, and direct-to-consumer (DTC) telemedicine visits in particular, is growing rapidly.1,2 DTC telemedicine (access to a physician via videoconference for a fee) provides obvious benefits for families, including convenience and, for some, lower out-of-pocket costs. A substantial proportion of DTC telemedicine services for children are for respiratory tract infections (RTIs). We applaud the careful and dispassionate analysis of diagnosis, antibiotic prescribing, and patient satisfaction related to RTI treatment that was published in this month’s Pediatrics by Foster et al.3 This study, along with that of Ray et al4 in a previous issue of Pediatrics , reveals the promise of DTC telemedicine, along with attendant risks of antibiotic overuse in pediatric outpatient settings. By using data on 12 842 completed RTI encounters with 560 physicians from a large, national DTC telemedicine provider, Foster et al3 were able to assess factors associated with antibiotic prescribing as well as parents’ satisfaction with the encounters. Their well-executed study includes a broad cross-section of patients across the country, increasing generalizability. The “headline” is that 55% of the visits resulted in antibiotic prescribing, consistent with other recent research on DTC treatment and more than what is suggested in other studies … Address correspondence to Eli Sprecher, MD, MPP, Division of General Pediatrics, Department of Pediatrics, Boston Children’s Hospital, 300 Longwood Ave, Boston, MA 02215.

Breastfeeding in Medicine: Time to Practice What We Preach.

At first, breastfeeding was not at all what I had imagined. To this day, I wince when I recall the toe-curling pain that coursed through my body each time my daughter’s tiny newborn mouth latched onto my breast, a sensation that stood in stark contrast to the exhilarating magic of her existence. Despite prenatal preparation, supportive family, and knowledgeable physicians, nurses, and lactation consultants, the early days of breastfeeding were more challenging than I had ever imagined. The physical and emotional intensity of serving as this small human’s primary source of fluid, nutrition, and comfort was simply overwhelming. More than once, with nipples cracked and bleeding, I sat and cried. How could something so simple, so fundamental, so primal, be so hard? More than 70 months of breastfeeding later, nursing my 4 daughters is one of my proudest, most precious accomplishments. The hard work and tears paid off; by the time my youngest infants were born, they latched like champions, and breastfeeding was second nature. At many points along the way, however, achieving this goal seemed in irreconcilable conflict with a career in medicine. To be clear, as a pediatrician I support parents feeding their infants in whatever way is best for their family without judgment. The history and politics of what (and by whom) infants are fed is long and storied, rife with deep racial, ethnic, and socioeconomic inequities that persist in a variety of forms to this day. Some contend that, driven by ideology, the benefits of breast … Address correspondence to Phoebe Danziger, MD, Division of General Pediatrics, Department of Pediatrics, University of Michigan, 1540 E Hospital Dr, Ann Arbor, MI 48109.

Overuse Stewardship: An Ongoing Problem That Must Be Tackled.

In this issue of Pediatrics , Tchou et al1 perform a retrospective analysis of administrative data and find that children’s hospitals differ in their use of electrolyte testing for common inpatient conditions such as constipation and gastroenteritis. This should not come as a surprise. It is well established that children’s hospitals differ in management and outcomes for many common conditions.2 However, this study demonstrates a bigger problem. Hospitals have similar testing patterns across conditions, even after adjusting for patient factors. In other words, some hospitals test at either high or low rates regardless of the condition. As the authors state, there appears to be “a culture of testing.” The variability reported by Tchou et al1 is likely a function of both underuse and overuse. Whereas underuse is problematic, overuse of medical tests is a public health problem. It is an expensive and ethical problem affecting the health and well-being of entire hospitals and communities.3 The Congressional Budget Office estimates that doctors spend up to 5% of the national gross domestic product on … Address correspondence to Joel S.

Addressing Social Determinants of Health: Challenges and Opportunities in a Value-Based Model.

* Abbreviations: ACO — : accountable care organization CMS — : Center for Medicare and Medicaid Services SDoH — : social determinants of health Two forces are reverberating within the US health care system. The first is the medical system’s recognition that addressing a patient’s social circumstances is necessary to promote health and prevent disease. Pediatrics has long espoused the strong influence of family and social conditions on children’s wellbeing. The second force is movement away from fee-for-service reimbursement to a value-based model in which payment is based on quality measures and health outcomes. This value-based system, which was first tested in private insurers and Medicare, has now been extended into Medicaid, which is the largest insurer of US children. By 2020, accountable care organizations (ACOs) will cover 100 million Americans.1 These forces’ convergence is influencing Medicaid-related health policies. Medicaid managed-care-organization programs in 30 states are encouraging screening for social needs and providing referrals for social services. Some statewide Medicaid ACO programs require social determinants of health (SDoH) interventions (eg, housing programs) and include health-related social-need screening as a quality measure.2 The Center for Medicare and Medicaid Services (CMS) also recently announced the Integrated Care for Kids Model, a child-centered service delivery and state payment model that is aimed at reducing expenditures and improving quality of care for children through the prevention, early identification, and treatment of behavioral and physical health needs.

The Transition Journey: Time to Systematically Address Transition Planning to Adult Health Care.

* Abbreviation: YSHCN — : youth with special health care needs Since the 1970s, researchers and clinicians have documented the difficulties and subsequent poor health outcomes experienced by youth with special health care needs (YSHCN) during the transition from pediatric to adult health care. In 2002, Pediatrics published the American Academy of Pediatrics recommendation of improving the transition of care for YSHCN from pediatric- to adult-focused care1 as a step toward meeting the goals of Healthy People 2010 . The recommendations specified that all YSHCN have appropriate transition and transfer planning through education and generation of a transfer summary. The goal was to ensure “high-quality, developmentally appropriate health care services are available in an uninterrupted manner as the person moves from adolescence” to “maximize lifelong functioning and well-being for all youth”2 regardless of whether the individual has a special health care need.

Stress As a Link Between Childhood Trauma and Preterm Delivery.

* Abbreviation: OHC — : out-of-home care In an intriguing article by Liu et al,1 “Out-of-Home Care and Subsequent Preterm Delivery: An Intergenerational Cohort Study,” in the current issue of Pediatrics , the authors report on the elevated rates of preterm delivery among women with a history of out-of-home care (OHC) before and after the age of 10 years. The authors framed their study using the science of toxic stress and its known impact on health outcomes as the theoretical construct and using OHC as a proxy for early life adversity. Based in Sweden, this study reinforces the value of large national birth cohort databases and linked data sets using unique identifiers in evaluating the impact of population-level health risk factors on outcomes. This approach enabled the authors to study a variety of maternal psychosocial, health, mental health, and perinatal risk factors and arrive at the conclusion that maternal childhood adversity made a moderate contribution to the risk for preterm delivery over and above those other factors. The complex ways in which childhood adversity negatively impacts long-term health and well-being are still being unraveled but are important to understand in terms of opportunities for prevention and intervention.

In an effort to lower the average age of diagnosis, considerable efforts are being made to promote early ASD screening.3–5 Two predominant strategies exist: broad-based developmental surveillance and targeted ASD screening.6,7 Although there are data to support each strategy, targeted ASD screening has recently gained popularity. The American Academy of Pediatrics, for example, recommends all children receive an ASD-specific screener at their 18- and 24-month well-child visit, and it proactively supports these guidelines with resources and trainings.3 A number of studies support ASD-specific screeners (the Modified Checklist for Autism in Toddlers [MCHAT] and the Modified Checklist for Autism in Toddlers-Revised [MCHAT-R]) for detecting early ASD … Address correspondence to Sarabeth Broder-Fingert, MD, MPH, Division of General Pediatrics, Boston University School of Medicine, 850 Harrison Ave, Room 310A, Boston, MA 02118.

Learning From National and State Trends in Sudden Unexpected Infant Death.

* Abbreviation: SUID — : sudden unexpected infant death In their analysis of national and state trends in US sudden unexpected infant death (SUID) rates in this month’s issue of Pediatrics , Erck Lambert et al1 demonstrate that declines in SUID rates have plateaued for the past 2 decades. The state-by-state data in which large disparities in SUID rates are shown should both raise alarm in the 22 states where rates are increasing and bring light to prevention efforts in the 9 states with the largest declines. Widespread education about safe sleep environments (eg, the Back to Sleep campaign) was associated with large decreases in SUID rates between 1990 and 2002. However, the effectiveness of such campaigns may have peaked as they have encountered cultural barriers, Internet misinformation, and countercampaigns. In light of this, how should we, as health care and public health professionals, proceed? First, we should recognize that among developed countries, the United States has the highest SUID rate. In a recent international comparison, researchers found that among 8 developed countries, the United States had the highest mean 2002–2010 postneonatal mortality rates (of which SUID comprises the majority) at 2.25 per 1000 live births, ∼70% higher than the other countries; only New Zealand, at 2.14 per 1000 live births, came close.2 To understand these differences, we must begin to look at variations in national policies. Of these countries, the United States is the only one that does not provide universal health care,3 home visitors in the neonatal period,4 and universal paid maternity leave.5 All of these are important protective factors for infant mortality.6–8 Additionally, these policies may have positive downstream effects on parental practices.

Detecting heart rate from fNIRS based brain signals

Event Abstract Back to Event Detecting heart rate from fNIRS based brain signals Ahmet S. Kurt1 and Hasan Ayaz1, 2, 3* 1 Drexel University, School of Biomedical Engineering, Science and Health Systems, United States 2 University of Pennsylvania, Department of Family and Community Health, United States 3 Children's Hospital of Philadelphia, The Division of General Pediatrics, United States Functional near-infrared spectroscopy (fNIRS) is a noninvasive and portable optical brain imaging technique that detects changes in cerebral blood oxygenation related to human brain functions. It uses near infrared light to measure changes in oxygenated hemoglobin (oxy-Hb) and deoxygenated hemoglobin (deoxy-Hb) levels due to the hemodynamic response. It has been utilized for study diverse array of brain function in healthy and clinical populations, from babies to elderly, and cognitive, affective to motor function. fNIRS signals collected from the brain contains multiple components specifically physiological correlates such as respiration and heart rate (HR). In fact, near infrared based sensors have been widely used for heart rate detection in clinical settings such as finger pulse oximetry. However, in neuroimaging studies, physiological components are considered noise, and they discarded during preprocessing using specially designed temporal, spatial or frequency filters. Accessing systemic response could be useful in neuroimaging settings and extracting them reliably from cortical fNIRS data would eliminate any additional dedicated sensor. In this work, our objective is to provide an overview of methods for extracting heart rate related signal from brain based fNIRS data. Common methodologies from the literatures will highlighted and assessed for practical field use and for experiments in real world settings. By accurately analyzing RR-intervals in HR related signal, detected variation can be used to measure autonomic nervous system. This variation, called Heart Rate Variability (HRV), is a valuable biomarker for understating human state in healthy and diverse clinical conditions. Identification of robust algorithms that can be generalized for detecting heartbeats, and calculating HR and HRV can potentially be used: i) to improve signal to noise ratio in functional neuroimaging research and ii) to complement brain data to help understand human workload while engaged with a machine or computerized tasks.
