Influence of Preterm Birth and Environmental Context on Academic Performance and Neurodevelopmental Outcomes.

BACKGROUND: Preterm birth affects 10% of all births annually in the United States. Outcomes of people born preterm are challenging to predict because of multiple influences, including gestational age, birth weight, and social and environmental contexts, that contribute to an individual's growth and developmental trajectory. The influence of toxic stress is underrepresented in the literature assessing preterm birth outcomes. OBJECTIVES: The current analyses use the eco-bio-developmental model of poverty and preterm birth as a framework to model the pathways among toxic stress, preterm birth, and neurodevelopmental outcomes. Poverty and toxic stress were hypothesized to increase the risk for impaired neurodevelopmental and academic outcomes-both directly and indirectly. METHODS: The analytic sample of 55,873 children aged 6-17 years was derived from the National Survey of Children's Health 2020-2021. Structural equation models with combined measurement and path models for each dependent variable were constructed using latent toxic stress variables. The structural path equations included direct paths from the latent measure of prenatal toxic stress, preterm birth status, and the latent measure of childhood toxic stress to the neurodevelopmental outcome, as well as an indirect, mediated path from prenatal toxic stress through preterm birth status to the outcome. RESULTS: Across models, higher levels of prenatal toxic stress were significantly associated with preterm birth and lower birth weight ranges. Preterm low birth weight status was associated with a greater likelihood of neurodevelopmental impairment, repeating a grade, and special education plans. The predicted probabilities of neurodevelopmental impairment, repeating grades, and special education plans are significantly higher with above-average levels of exposure to prenatal and childhood toxic stress. DISCUSSION: There is a need for prospective studies that assess predictors and outcomes of preterm birth that are stratified by gestational age and consider the timing, chronicity, and influence of toxic stress and environmental exposures. There is an imperative for public health programs and policies designed to support families, caregivers, and children to address the individual and structural social determinants of health that contribute to toxic stress, thereby increasing preterm birth rates and negatively affecting the outcomes of children born preterm.

Family experiences reported by healthcare worker parents during the COVID-19 pandemic.

PURPOSE: Parents, who were working as essential frontline healthcare workers experienced unique stressors during the COVID-19 pandemic including disruption of regular routines, long lapses away from family, extreme work stress and subsequent difficulty in compartmentalizing work-related concerns when at home. The purpose of this study was to assess COVID-19 exposure and impact of frontline healthcare workers who are parents. DESIGN & METHODS: This study quantitatively assessed the COVID-19 exposure and impact and qualitatively explored perceptions of parents of children 9 to 17 years of age, who were also frontline healthcare workers. RESULTS: Participants (N = 79) using the COVID-19 Exposure and Family Impact Survey (CEFIS) reported exposure mean scores of 10.03 (SD = 2.63); and impact scores mean scores of 3.18 (SD = 0.46). Thematic analysis identified four themes, each with 2 subthemes: 1) family stressors increased (e.g., concerns about health and safety, losses of lifestyle patterns); 2) changes in children's health and well-being (e.g., isolation from family and friends, mental health problems); 3) virtual school difficulties (e.g., parent and student challenges, home school option); 4) skill building opportunities (e.g., enhanced emotional connections, increased family activities). CONCLUSION: The CHAMPS Family Health Study suggests that families of essential workers are especially vulnerable to the effect of COVID-19, as are those families of essential workers who include child/ren with special health care needs. PRACTICE IMPLICATIONS: Preparation for future emergencies requires strategies to mitigate consequences and promote well-being. These results highlight the need for supportive approaches to decrease the negative consequences of stress and to augment skills for family connection and cooperation.

Reinfection and Risk Behaviors After Treatment of Hepatitis C Virus Infection in Persons Receiving Opioid Agonist Therapy : A Cohort Study.

BACKGROUND: Hepatitis C virus (HCV) reinfection after successful treatment may reduce the benefits of cure among people who inject drugs. OBJECTIVE: To evaluate the rate of HCV reinfection for 3 years after successful treatment among people receiving opioid agonist therapy (OAT). DESIGN: A 3-year, long-term, extension study of persons enrolled in the CO-STAR (Hepatitis C Patients on Opioid Substitution Therapy Antiviral Response) study (ClinicalTrials.gov: NCT02105688). SETTING: 55 clinical trial sites in 13 countries. PATIENTS: Aged 18 years and older with chronic HCV infection with genotypes 1, 4, or 6 receiving stable OAT. INTERVENTION: No treatments were administered. MEASUREMENTS: Serum samples were assessed for HCV reinfection. Urine drug screening was performed. RESULTS: Among 296 participants who received treatment, 286 were evaluable for reinfection and 199 were enrolled in the long-term extension study. The rate of HCV reinfection was 1.7 [95% CI, 0.8 to 3.0] per 100 person-years; 604 person-years of follow-up). A higher rate of reinfection was seen among people with recent injecting drug use (1.9 [95% CI, 0.5 to 4.8] per 100 person-years; 212 person-years). Ongoing drug use and injecting drug use were reported by 59% and 21% of participants, respectively, at the 6-month follow-up visit and remained stable during 3 years of follow-up. LIMITATIONS: Participants were required to be 80% adherent to OAT at baseline and may represent a population with higher stability and lower risk for HCV reinfection. Rate of reinfection may be underestimated because all participants did not continue in the long-term extension study; whether participants who discontinued were at higher risk for reinfection is unknown. CONCLUSION: Reinfection with HCV was low but was highest in the first 24 weeks after treatment completion and among people with ongoing injecting drug use and needle-syringe sharing.

A test of differential susceptibility in behavior trajectories of preterm infants from preschool to adulthood.

Preterm birth predisposes children to internalizing and externalizing behaviors that may persist into adolescence resulting in adult mental health conditions. Social and caregiving contexts, particularly for vulnerable infants born preterm, influence long-term outcomes, but mechanisms are not clearly understood. Healthcare teams caring for those born preterm face difficulty predicting who will be most affected by risk, who will most benefit, and the optimal timing of intervention. Differential susceptibility theory offers an alternative to the traditional risk-only assessments and theories by positing that individuals may be more, or less, susceptible to environmental influences. A sample of preterm- and term-born infants were followed from birth to 23 years of age. Mixed model repeated measures analyses of internalizing and externalizing behaviors were utilized for the comparison groups (N = 214; observations = 1070). Environmental contexts were indexed as proximal protection (low, moderate, high) and medical risk (low, moderate, high). Personal characteristic covariates of sex, race, socioeconomic status, and cognition were modeled. Internalizing behavior trajectories varied significantly over time. Early proximal protective environments conferred a sustained positive influence on behaviors. There is partial support for differential susceptibility theory suggesting that prematurity, as a malleability characteristic enables absorption of both the positive and negative influences of the environment, with greater intensity that those without malleability. The current analyses suggest lasting effects of the preschool age proximal environment on internalizing and externalizing behaviors in young adulthood for those born preterm. Understanding these nuances may aid healthcare professionals in the promotion and timing of interventions to support the child and family. The current manuscript reflects ongoing analyses of longitudinal data. No patient or public contribution to the analyses were required for testing the differential susceptibility theory. The authors would solicit patient or public contribution when implementing practice or policy changes based on the results.

Diagnostic Reasoning Competency and Accuracy by Nurse Practitioner Students Following the Use of Structured Reflection in Simulation: A Mixed-Methods Experiment.

AIM: The aim of this study was to examine the effect of structured reflection used during a simulated patient's diagnostic workup on diagnostic reasoning competency and accuracy and explore participants' cognitive bias experience and perceived utility of structured reflection. BACKGROUND: Reasoning flaws may lead to diagnostic errors. Medical learners who used structured reflection demonstrated improved diagnosis accuracy. METHOD: Embedded mixed-methods experiment examined diagnostic reasoning competency and accuracy of nurse practitioner students who did and did not use structured reflection. Cognitive bias experience and perceptions of structured reflection's utility were explored. RESULTS: Diagnostic Reasoning Assessment mean competency scores and categories were not changed. Accuracy trended toward improvement with structured reflection. The theme, diagnostic verification, prompted diagnosis change by both structured reflection users and control participants. CONCLUSION: Despite no changes in quantitative outcomes, explicit users of structured reflection believed that this strategy is helpful to their reasoning, and control participants used the strategy's components with the same noted benefits.

In-Home COVID-19 Testing for Children With Medical Complexity: Feasibility and Association With School Attendance and Safety Perceptions.

The REstarting Safe Education and Testing program for children with medical complexity was implemented in May 2021 at the University of Wisconsin to evaluate the feasibility of in-home rapid antigen COVID-19 testing among neurocognitively affected children. Parents or guardians administered BinaxNOW rapid antigen self-tests twice weekly for three months and changed to symptom and exposure testing or continued surveillance. In-home testing was feasible: nearly all (92.5%) expected tests were conducted. Symptomatic testing identified seven of nine COVID-19 cases. School safety perceptions were higher among those opting for symptom testing. Clinical Trials.gov identifier: NCT04895085. (Am J Public Health. 2022;112(S9):S878-S882. https://doi.org/10.2105/AJPH.2022.306971).

Caregiver perceptions of in-home COVID-19 testing for children with medical complexity: a qualitative study.

BACKGROUND: In-home direct antigen rapid testing (DART) plays a major role in COVID-19 mitigation and policy. However, perceptions of DART within high-risk, intellectually impaired child populations are unknown. This lack of research could negatively influence DART uptake and utility among those who stand to benefit most from DART. The purpose of this study was to describe caregivers' perceptions of an in-home COVID-19 DART regimen in children with medical complexity, including the benefits and limitations of DART use. METHODS: This qualitative study was a subproject of the NIH Rapid Acceleration of Diagnostics Underserved Populations research program at the University of Wisconsin. We combined survey data and the thematic analysis of semi-structured interview data to understand caregivers' perceptions of in-home COVID-19 testing and motivators to perform testing. Caregivers of children with medical complexity were recruited from the Pediatric Complex Care Program at the University of Wisconsin (PCCP). Data were collected between May and August 2021. RESULTS: Among n = 20 caregivers, 16/20 (80%) of their children had neurologic conditions and 12/20 (60%) used home oxygen. Survey data revealed that the largest caregiver motivators to test their child were to get early treatment if positive (18/20 [90%] of respondents agreed) and to let the child's school know if the child was safe to attend (17/20 [85%] agreed). Demotivators to testing included that the child could still get COVID-19 later (7/20 [35%] agreed), and the need for officials to reach out to close contacts (6/20 [30%] agreed). From interview data, four overarching themes described perceptions of in-home COVID-19 testing: Caregivers perceived DART on a spectrum of 1) benign to traumatic and 2) simple to complex. Caregivers varied in the 3) extent to which DART contributed to their peace of mind and 4) implications of test results for their child. CONCLUSIONS: Although participants often described DART as easy to administer and contributing to peace of mind, they also faced critical challenges and limitations using DART. Future research should investigate how to minimize the complexity of DART within high-risk populations, while leveraging DART to facilitate safe school attendance for children with medical complexity and reduce caregiver burden.

A Protocol to Assess Adult Outcomes at 30 Years Following Preterm Birth.

BACKGROUND: Among the most intense adversity experiences for infants is premature birth. Early birth marks the beginning of a life course that broadly affects families, healthcare, education, social systems, and the survivors themselves. For many, the transition to adulthood is challenging and often hampered by cognitive, physical and mental health, and motor and independence difficulties. OBJECTIVES: The aim of this study was to share a comprehensive protocol of a 10th follow-up study of premature infants in their 30s. The protocol accounts for stress during the neonatal period, the cumulative context (risk and protection) of development, biological and epigenetic mechanisms, and individual resilience. METHODS: The prospective, five-group longitudinal design includes 215 term-born and preterm-born individuals with various neonatal morbidities at ages 30-35 years. Adult outcomes include health, adaptive, executive function, work, and social competence. Novel measures are four system indicators of allostatic load (AL) and epigenetics. Contextual measures include socioeconomic risk and individual resilience. All measures were selected based on coherence with constructs of the scientific aims, strong psychometrics, continuity for repeated measures, and minimal subject burden. Objective assessments include body composition imaging, exercise testing, blood and saliva collection, and actigraphy. The two-phase protocol takes approximately 8 hours. DISCUSSION: After an 11-month COVID-19 pause, participant response has been strong. As of May 2022, 75 participants have completed the full protocol, and 99 have consented to participate. When socioeconomic risk is controlled, we hypothesize that life course trajectories in physical and psychological health, adaptive function, and executive function will differ between term and preterm neonatal morbidity groups. AL will vary across groups and contribute to outcomes. We expect proximal protection and resilience to mediate the cumulative medical and socioeconomic risk and AL. Epigenome-wide DNA methylation, with estimates of age acceleration, will be examined across groups and explored in longitudinal associations with medical risk, socioeconomic status, and protection. To our knowledge, this is the only U.S. study of premature infants aged 30-35 years. With millions of preterm-born individuals reaching adulthood, the protocol incorporates molecular and genetic biomarkers in a life course developmental examination to inform the timing and content of interventions.

Association Between Neighborhood Disadvantage and Pediatric Readmissions.

OBJECTIVE: Although individual-level social determinants of health (SDH) are known to influence 30-day readmission risk, contextual-level associations with readmission are poorly understood among children. This study explores associations between neighborhood disadvantage measured by Area Deprivation Index (ADI) and pediatric 30-day readmissions. METHODS: This retrospective cohort study included discharges of patients aged < 20 years from Maryland's 2013-2016 all-payer dataset. The ADI, which quantifies 17 indicators of neighborhood socioeconomic disadvantage within census block groups, is used as a proxy for contextual-level SDH. Readmissions were identified with the 30-day Pediatric All-Condition Readmissions measure. Associations between ADI and readmission were identified with generalized estimating equations adjusted for patient demographics and clinical severity (Chronic Condition Indicator [CCI], Pediatric Medical Complexity Algorithm [PMCA], Index Hospital All Patients Refined Diagnosis Related Groups [APR-DRG]), and hospital discharge volume. RESULTS: Discharges (n = 138,998) were mostly female (52.7%), publicly insured (55.1%), urban-dwelling (93.0%), with low clinical severity levels (0-1 CCIs [82.3%], minor APR-DRG severity [48.4%]). Overall readmission rate was 4.0%. Compared to the least disadvantaged ADI quartile, readmissions for the most disadvantaged quartile were significantly more likely (aOR 1.19, 95% CI 1.09-1.30). After adjustment, readmissions were associated with public insurance and indicators of medical complexity (higher number of CCIs, complex-chronic disease PMCA, and APR-DRG severity). CONCLUSION: In this all-payer, statewide sample, living in the most socioeconomically disadvantaged neighborhoods independently predicted pediatric readmission. While the relative magnitude of neighborhood disadvantage was modest compared to medical complexity, disadvantage is modifiable and thus represents an important consideration for prevention and risk stratification efforts.

Association of Patient Characteristics With Postoperative Mortality in Children Undergoing Tonsillectomy in 5 US States.

Importance: The rate of postoperative death in children undergoing tonsillectomy is uncertain. Mortality rates are not separately available for children at increased risk of complications, including young children (aged <3 y) and those with sleep-disordered breathing or complex chronic conditions. Objective: To estimate postoperative mortality following tonsillectomy in US children, both overall and in relation to recognized risk factors for complications. Design, Setting, and Participants: Retrospective cohort study based on longitudinal analysis of linked records in state ambulatory surgery, inpatient, and emergency department discharge data sets distributed by the Healthcare Cost and Utilization Project for 5 states covering 2005 to 2017. Participants included 504 262 persons younger than 21 years for whom discharge records were available to link outpatient or inpatient tonsillectomy with at least 90 days of follow-up. Exposures: Tonsillectomy with or without adenoidectomy. Main Outcome and Measures: Postoperative death within 30 days or during a surgical stay lasting more than 30 days. Modified Poisson regression with sample weighting was used to estimate postoperative mortality per 100 000 operations, both overall and in relation to age group, sleep-disordered breathing, and complex chronic conditions. Results: The 504 262 children in the cohort underwent a total of 505 182 tonsillectomies (median [IQR] patient age, 7 [4-12] years; 50.6% females), of which 10.1% were performed in young children, 28.9% in those with sleep-disordered breathing, and 2.8% in those with complex chronic conditions. There were 36 linked postoperative deaths, which occurred a median (IQR) of 4.5 (2-20.5) days after surgical admission, and most of which (19/36 [53%]) occurred after surgical discharge. The unadjusted mortality rate was 7.04 (95% CI, 4.97-9.98) deaths per 100 000 operations. In multivariable models, neither age younger than 3 years nor sleep-disordered breathing was significantly associated with mortality, but children with complex chronic conditions had significantly higher mortality (16 deaths/14 299 operations) than children without these conditions (20 deaths/490 883 operations) (117.22 vs 3.87 deaths per 100 000 operations; adjusted rate difference, 113.55 [95% CI, 51.45-175.64] deaths per 100 000 operations; adjusted rate ratio, 29.39 [95% CI, 13.37-64.62]). Children with complex chronic conditions accounted for 2.8% of tonsillectomies but 44% of postoperative deaths. Most deaths associated with complex chronic conditions occurred in children with neurologic/neuromuscular or congenital/genetic disorders. Conclusions and Relevance: Among children undergoing tonsillectomy, the rate of postoperative death was 7 per 100 000 operations overall and 117 per 100 000 operations among children with complex chronic conditions. These findings may inform decision-making for pediatric tonsillectomy.

Team Cognition in Handoffs: Relating System Factors, Team Cognition Functions and Outcomes in Two Handoff Processes.

OBJECTIVE: This study investigates how team cognition occurs in care transitions from operating room (OR) to intensive care unit (ICU). We then seek to understand how the sociotechnical system and team cognition are related. BACKGROUND: Effective handoffs are critical to ensuring patient safety and have been the subject of many improvement efforts. However, the types of team-level cognitive processing during handoffs have not been explored, nor is it clear how the sociotechnical system shapes team cognition. METHOD: We conducted this study in an academic, Level 1 trauma center in the Midwestern United States. Twenty-eight physicians (surgery, anesthesia, pediatric critical care) and nurses (OR, ICU) participated in semi-structured interviews. We performed qualitative content analysis and epistemic network analysis to understand the relationships between system factors, team cognition in handoffs and outcomes. RESULTS: Participants described three team cognition functions in handoffs-(1) information exchange, (2) assessment, and (3) planning and decision making; information exchange was mentioned most. Work system factors influenced team cognition. Inter-professional handoffs facilitated information exchange but included large teams with diverse backgrounds communicating, which can be inefficient. Intra-professional handoffs decreased team size and role diversity, which may simplify communication but increase information loss. Participants in inter-professional handoffs reflected on outcomes significantly more in relation to system factors and team cognition (p < 0.001), while participants in intra-professional handoffs discussed handoffs as a task. CONCLUSION: Handoffs include team cognition, which was influenced by work system design. Opportunities for handoff improvement include a flexibly standardized process and supportive tools/technologies. We recommend incorporating perspectives of the patient and family in future work.

Nursing Faculty Experiences During the COVID-19 Pandemic Response.

AIM: The specific aim of the study was to describe nursing faculty experiences during the COVID-19 pandemic. BACKGROUND: Academic nursing experiences were disrupted due to the COVID-19 pandemic. There is concern that the resulting stress threatens nursing faculty emotional well-being. METHOD: A descriptive, quantitative study was conducted, exploring faculty academic and clinical roles during the COVID-19 pandemic, including perception of institutional support provided; faculty burnout, satisfaction, and well-being; and student support needs and well-being. RESULTS: Analyses were performed on 117 quantitative and 49 qualitative responses. Participants perceived support from academic institutions and increased need to provide emotional support to students. Most reported negative effects on well-being but did not report high levels of burnout. CONCLUSION: Nursing faculty are essential to the profession. Stress responses from the COVID-19 pandemic may not be fully realized. Nursing faculty require proactive and sustained institutional and personal support to provide exceptional ongoing education, build resilience, and support students.

Efficacy and safety of ruzasvir 60 mg and uprifosbuvir 450 mg for 12 weeks in adults with chronic hepatitis C virus genotype 1, 2, 3, 4 or 6 infection.

In clinical trials, the three-drug regimen of ruzasvir (RZR) 60 mg, uprifosbuvir (UPR) 450 mg and grazoprevir 100 mg, with or without ribavirin, has demonstrated promising efficacy and excellent tolerability across a wide range of hepatitis C virus (HCV)-infected individuals. The present study assessed the efficacy and safety of the two-drug combination of RZR 60 mg plus UPR 450 mg administered for 12 weeks in participants with HCV genotype (GT) 1-6 infection. In this open-label clinical trial, treatment-naive or -experienced and cirrhotic or noncirrhotic participants with chronic HCV GT1-6 infection received RZR 60 mg plus UPR 450 mg orally once daily for 12 weeks (NCT02759315/protocol PN035). The primary efficacy endpoint was sustained virologic response at 12 weeks after the end of therapy (SVR12). One hundred and sixty participants were enrolled. SVR12 rates were 96% (52 of 54) in participants with GT1a infection; 100% (15 of 15) in those with GT1b infection; 97% (28 of 29) in those with GT2 infection; 77% (30 of 39) in those with GT3 infection; 90% (18 of 20) in those with GT4 infection; and 67% (2 of 3) in those with GT6 infection. Drug-related adverse events (AEs) reported by >5% of participants were fatigue (n = 10, 6.3%) and diarrhoea (n = 9, 5.6%). Five participants reported a total of 11 serious AEs, none considered drug-related. One participant experienced on-treatment alanine aminotransferase/aspartate aminotransferase elevations that resolved without intervention. Data from the present study indicate that the combination of RZR 60 mg plus UPR 450 mg once daily for 12 weeks was well tolerated overall but was effective only for certain genotypes.

Inpatients Sign On: An Opportunity to Engage Hospitalized Patients and Caregivers Using Inpatient Portals.

BACKGROUND: Inpatient portals are online patient portals linked to electronic health records that provide hospitalized patients and caregivers secure access to real-time clinical information and tools to enhance their communication with providers and hospital experience. OBJECTIVE: The main objective of this commentary was to provide a perspective that inpatient portals are innovative tools poised to engage patients and caregivers during hospitalization and, thus, enhance patient-centered care. RESULTS: Inpatient portals are desired by patients and caregivers and may contribute to improved recognition of their inpatient care team, knowledge of their treatment plan and overall inpatient experience. A sociotechnical systems approach is recommended to mitigate potential unintended consequences of inpatient portal use and support effective portal design, implementation and evaluation. CONCLUSIONS: This article highlights the potential of using inpatient portals to engage hospitalized patients and caregivers and proposes next steps to evaluate this emerging technology.

Poverty, Toxic Stress, and Education in Children Born Preterm.

BACKGROUND: Preterm birth, defined as birth before the completion of 37 weeks of gestation, is a multifactorial global epidemic with psychosocial, economic, and physical ramifications affecting the child, family, and community at large. Toxic stress-the results of exposure to adverse childhood experiences-results in changes to brain structure and function that negatively affects future health. OBJECTIVES: The aim of this study was to apply the eco-bio-developmental (EBD) model of poverty and preterm birth to the cross-sectional data of the 2016 National Survey of Children's Health to evaluate the associations between poverty, toxic stress, and prematurity on neurodevelopmental and educational outcomes. METHODS: A subset of data representing children ages 6-11 years old (n = 15,010) from the 2016 National Survey of Children's Health was used for multivariate analysis of demographic variables and neurodevelopmental and educational outcome variables. Pearson's chi-square, logistic regression, and interaction effects explored the relationships between prematurity, toxic stress, and poverty. RESULTS: Children in this sample born preterm had a higher incidence of toxic stress, poverty, developmental delay, learning disability, intellectual disability, speech/language disorders, attention-deficit disorder (ADD)/attention-deficit/hyperactivity disorder (ADHD), autism, and special education/early intervention plans. The combination of poverty, toxic stress, and preterm birth significantly increased the risk of these conditions. After accounting for gender, insurance coverage, race, and parental education, children in the sample born preterm were more likely to experience developmental delay, intellectual disability, speech/language disorder, learning disability, and ADD/ADHD. Toxic stress increased the incidence of ADD/ADHD and autism in both the preterm and full-term samples. DISCUSSION: The negative effect of poverty and toxic stress on children born preterm, as depicted by the eco-bio-developmental model, is supported by this analysis. Healthcare providers are encouraged to address the tripartite vulnerability resulting from prematurity, poverty, and toxic stress.

Hospitalizations for Ambulatory Care-Sensitive Conditions among Children with Chronic and Complex Diseases.

OBJECTIVE: To evaluate ambulatory-care sensitive (ACS) hospitalizations for children with noncomplex chronic diseases (NC-CD) and children with medical complexity (CMC), and identify associations with ambulatory care characteristics. Although ACS hospitalizations are potentially preventable in general populations, the specific ambulatory care predictors and influence of medical complexity on them is poorly understood. STUDY DESIGN: Retrospective cohort study of NC-CD and CMC hospitalizations at a children's hospital during 2007-2014, excluding labor/delivery and children over 21 years. Pediatric medical complexity algorithm identified NC-CD or CMC. ACS hospitalizations were identified using Agency for Healthcare Research and Quality indicator definitions. Demographic and ambulatory care characteristics were compared between ACS and non-ACS hospitalizations with logistic regression clustered by patient. Measures of ambulatory care during 2 years before admission were explored with 20% random sample of general pediatrics discharges. RESULTS: Among 4035 children with NC-CD, 14.6% of 4926 hospitalizations were ACS hospitalizations. Among 5084 CMC, 5.3% of 14 390 discharges were ACS hospitalizations. Among NC-CD discharges, ACS hospitalizations were more likely with no prior-year outpatient visits (OR 1.4, 95% CI 1.1-1.7) and less likely with timely well checks (OR 0.8, 95% CI 0.6-0.9) and phone encounters in the month before admission (OR 0.5, 95% CI 0.2-1.0). Among CMC discharges, the only association observed was with provider continuity (OR 0.3, 95% CI 0.1- 1.0). CONCLUSIONS: Provider continuity may be associated with fewer CMC ACS hospitalizations, however, measures of ambulatory care were more consistently associated with ACS hospitalizations for NC-CD. CMC may need more precise ACS hospitalization definitions.

Trends in Hospital Treatment of Empyema in Children in the United States.

OBJECTIVE: To evaluate trends in procedures used to treat children hospitalized in the US with empyema during a period that included the release of guidelines endorsing chest tube placement as an acceptable first-line alternative to video-assisted thoracoscopic surgery. STUDY DESIGN: We used National Inpatient Samples to describe empyema-related discharges of children ages 0-17 years during 2008-2014. We evaluated trends using inverse variance weighted linear regression and characterized treatment failure using multivariable logistic regression to identify factors associated with having more than 1 procedure. RESULTS: Empyema-related discharges declined from 3 in 100 000 children to 2 in 100 000 during 2008-2014 (P = .04, linear trend). There was no significant change in the proportion of discharges having 1 procedure (66.1% to 64.1%) or in the proportion having 2 or more procedures (22.1% to 21.6%). The proportion coded for video-assisted thoracoscopic surgery as the only procedure declined (41.4% to 36.2%; P = .03), and the proportions coded for 1 chest tube (14.6% to 20.9%; P = .04) and 2 chest tube procedures (0.9% to 3.5%; P < .01) both increased. The median length of stay for empyema-related discharges remained unchanged (9.3 days to 9.8 days; P = .053). Having more than 1 procedure was associated with continuous mechanical ventilation (adjusted OR, 2.7; 95% CI, 1.8-4.1) but not with age, sex, payer, chronic conditions, transfer admission, hospital size, or census region. CONCLUSIONS: The use of video-assisted thoracoscopic surgery to treat children in the US hospitalized with empyema seems to be decreasing without associated increases in length of stay or need for additional drainage procedures.

National Perspective of Health Outcomes of 8- to 11-Year-Old Children Born Prematurely and Their Full-Term Peers.

UNLABELLED: The specific aim of this study was to evaluate the health sequelae of preterm birth on children 8 to 11years of age as compared to same age children born at term; selected variables include special health care needs, chronic conditions, and caregiver perception of health. DESIGN/METHODS: A secondary data analysis was conducted to evaluate the health outcomes of children 8 to 11years of age who were born prematurely compared to a sample of children born at term. The 2011/2012 National Survey of Children's Health (NSCH) is a nationally representative telephone interview survey of parents/caregivers of children 0 to 17years of age. Preterm birth was determined by parent report of birth more than 3weeks early. RESULTS: Utilizing the Children with Special Health Care Needs (CSHCN) Screener, 35% of children born prematurely, compared to 24% of children born at term were identified as having a special health care need. The 5 most prevalent conditions were the same in both groups of 8 to 11year old children and in the larger total sample of children 2 to 17years of age. However 82% of children born prematurely were described by parents as having excellent or very good health. CONCLUSIONS: Premature birth places children at increased risk for conditions that impede the crucial activities of childhood (education, psychosocial development and play). These conditions may require both medications and increased health care services. IMPLICATIONS FOR PRACTICE: Understanding the relationship between preterm birth and ongoing health risks has the potential to inform the health care providers' ability to provide care that maximizes the potential of children born prematurely. Health care providers need to be cognizant of this risk, utilizing early screening and encouraging intervention and family supports.

Children and Adolescents with Chronic Kidney Disease: A Population at Risk for More Than Just Kidney Disease.

Health-related quality of life (HRQOL) of children and adolescents with chronic health conditions is a multifactorial concept that combines a child's perception and adaptation to physical, social, emotional, and school environments regardless of particular medical diagnosis. Children with chronic kidney disease (CKD) experience non-kidney specific co-morbidities, including depression, body image alterations, and sleep disturbance, that impair their daily lives. This article reviews the pediatric nephrology literature to highlight the evidence identifying these riskr to HRQOL and suggesting ways in which nurses in both nephrology and primary care are poised to identify and modify these risk factors.

A systematic analysis of cell cycle regulators in yeast reveals that most factors act independently of cell size to control initiation of division.

Upstream events that trigger initiation of cell division, at a point called START in yeast, determine the overall rates of cell proliferation. The identity and complete sequence of those events remain unknown. Previous studies relied mainly on cell size changes to identify systematically genes required for the timely completion of START. Here, we evaluated panels of non-essential single gene deletion strains for altered DNA content by flow cytometry. This analysis revealed that most gene deletions that altered cell cycle progression did not change cell size. Our results highlight a strong requirement for ribosomal biogenesis and protein synthesis for initiation of cell division. We also identified numerous factors that have not been previously implicated in cell cycle control mechanisms. We found that CBS, which catalyzes the synthesis of cystathionine from serine and homocysteine, advances START in two ways: by promoting cell growth, which requires CBS's catalytic activity, and by a separate function, which does not require CBS's catalytic activity. CBS defects cause disease in humans, and in animals CBS has vital, non-catalytic, unknown roles. Hence, our results may be relevant for human biology. Taken together, these findings significantly expand the range of factors required for the timely initiation of cell division. The systematic identification of non-essential regulators of cell division we describe will be a valuable resource for analysis of cell cycle progression in yeast and other organisms.
