Impact of Respiratory Developmental Stage on Sensitivity to Late Effects of Radiation in Pediatric Cancer Survivors.

ABSTRACT: Purpose:Pulmonary dysfunction is a prevalent and potentially debilitating late effect of pediatric cancer treatment. We postulated that age, as a surrogate for respiratory developmental status, might be associated with vulnerability to pulmonary injury. Materials and Methods:Sixty-one children treated with lung radiation at our institution who had undergone a pulmonary function test (PFT) between 1995 and 2016 were analyzed. Data collection included age at diagnosis and treatment, radiation dose and location, spirometry, and plethysmography results. PFTs were normalized according to age, sex, height, and ethnicity, and transformed into standardized z-scores. Obstructive disease was defined as forced expiratory volume in 1 second z score/forced vital capacity z score < -1.645, restrictive as total lung capacity z score < -1.645, and abnormal diffusion as diffusing capacity of the lung for carbon monoxide z score < -1.645. We determined the incidence of PFT abnormalities in our population and estimated the relative risk of developing pulmonary abnormalities using models adjusted for age. Results:At a mean age of 24 years (range, 12-31) and time from radiation of 9 years (range, 1-20), the cumulative incidence of any pulmonary abnormality was 34.4%. Among patients with an abnormal PFT, diffusing and restrictive abnormalities were most common (57.1% and 52.4%). When stratified by age at radiation treatment, 66.7% of patients <5 years had a PFT abnormality, compared with 47.6% for aged 5 to 13 and 20.6% for patients >13. Compared with patients >13 years, those <5 years and 5 to 13 years at radiation treatment had a significantly increased risk of an abnormal PFT with an odds ratio of 7.71 (95% confidence interval, 1.17, 51.06) and 3.51 (95% confidence interval, 1.06, 11.57), respectively (P <. 035). Furthermore, this association remained when examining each type of abnormality (P > .05). Conclusions:PFT abnormalities were common among our cohort of childhood cancer survivors treated with lung radiation. Younger age at treatment is associated with an increased risk of developing pulmonary dysfunction, presumably owing to developmental immaturity.

Project description:Simple Summary Due to previous cancer and its treatments, long-term childhood cancer survivors (CCS) are at risk of developing medical comorbidities, as well as socioeconomic vulnerability. Above all, work placement, financial independence, and job satisfaction can represent burdensome areas for some CCS. Regarding this topic, it is important to consider the variety of country-specific educational and vocational systems. The aim of this study is to provide a description of the occupational status of CCS in the Italian socio-economic scenery and to evaluate the association between late effects and unemployment and late effects and job satisfaction. Our data contribute to the description of the different country scenery of work placement for CCS in Europe and agree with previous literature on the impact of severe late effects on occupation. Future research in this field can be focused on interventions to improve CCS in obtaining jobs suitable for their health. Abstract Late effects of cancer and its treatments during childhood or adolescence can impact work placement and increase the risk of unemployment. The aim of this study is to describe the work placement and the perceived job and economic satisfaction of long-term childhood cancer survivors (CCS). Jobs have been categorized according to the International Standard Classification of Occupations version 08 (ISCO-08), and satisfaction has been evaluated through the Satisfaction Profile (SAT-P). Out of 240 CCS (female = 98) included: 53 were students, 46 were unemployed and 141 were employed. Within unemployed survivors, 89.13% were affected by late effects (n = 41). The presence of at least one severe late effect was significantly associated with the probability of unemployment (OR 3.21; 95% CI 1.13–9.12, p < 0.050), and having any late effect was inversely related to the level of satisfaction of the financial situation of unemployed CCS (b −35.47; 95% CI −59.19, −11.74, p = 0.004). Our results showed that being a survivor with severe comorbidities has a significantly negative impact on occupation and worsens the perception of satisfaction of economic situations. Routinary follow-up care of CCS should include the surveillance of socioeconomic development and provide interventions, helping them to reach jobs suitable for their health.

Project description:The quality of parenting shapes the development of children's emotion regulation. However, the relative importance of parenting in different developmental stages, indicative of sensitive periods, has rarely been studied. Therefore, we formulated four hypothetical developmental timing models to test the stage-specific effects of mothering and fathering in terms of parental autonomy and intimacy in infancy, middle childhood, and late adolescence on adolescents' emotion regulation. The emotion regulation included reappraisal, suppression, and rumination. We hypothesized that both mothering and fathering in each developmental stage contribute unique effects to adolescents' emotion regulation patterns. The participants were 885 families followed from pregnancy to late adolescence. This preregistered study used data at the children's ages of 1 year, 7 to 8 years, and 18 years. At each measurement point, maternal and paternal autonomy and intimacy were assessed with self- and partner reports using the Subjective Family Picture Test. At the age of 18 years, adolescents' reappraisal and suppression were assessed using the Emotion Regulation Questionnaire and rumination using the Cognitive Emotion Regulation Questionnaire. Stage-specific effects were tested comparing structural equation models. Against our hypotheses, the results showed no effects of mothering or fathering in infancy, middle childhood, or late adolescence on adolescents' emotion regulation patterns. The results were consistent irrespective of both the reporter (i.e., self or partner) and the parental dimension (i.e., autonomy or intimacy). In addition to our main results, there were relatively low agreement between the parents in each other's parenting and descriptive discontinuity of parenting across time (i.e., configural measurement invariance). Overall, we found no support for the stage-specific effects of parent-reported parenting in infancy, middle childhood, or late adolescence on adolescents' emotion regulation. Instead, our findings might reflect the high developmental plasticity of emotion regulation from infancy to late adolescence.

Project description:ObjectivesMuch of the research related to pediatric acute respiratory distress syndrome has focused on inhospital mortality and interventions affecting this outcome. Limited data exist on survivors' morbidity, hospital disposition, and 1-year survival. The aim of this study was to determine new morbidity rate, discharge disposition, and 1-year mortality for survivors of pediatric acute respiratory distress syndrome.DesignSecondary analysis of prospective cohort study.SettingQuaternary children's hospital.PatientsThree-hundred sixteen mechanically ventilated children with pediatric acute respiratory distress syndrome (Berlin and Pediatric Acute Lung Injury Consensus Conference criteria) between July 2011 and December 2014.InterventionsNone.Measurements and main resultsWe performed secondary analysis of a prospectively recruited cohort of 316 mechanically ventilated children with pediatric acute respiratory distress syndrome between July 2011, and December 2014. Preillness and hospital discharge Functional Status Scale score were determined via chart review, and factors associated with new morbidity, defined as an increase of Functional Status Scale score of 3 or more, were analyzed. Demographic variables, pediatric acute respiratory distress syndrome characteristics, and ventilator management were tested for association with development of new morbidity, discharge disposition, and 1-year mortality. Inhospital mortality of pediatric acute respiratory distress syndrome was 13.3% (42/316). Of 274 survivors to hospital discharge, new morbidity was seen in 63 patients (23%). Discharge to rehabilitation rate was 24.5% (67/274) and associated with development of new morbidity. One- and 3-year mortality of survivors was 5.5% (15 deaths) and 8% (22 deaths) and was associated with baseline Functional Status Scale, immunocompromised status, Pediatric Risk of Mortality III, and organ failures at pediatric acute respiratory distress syndrome onset, but not with pediatric acute respiratory distress syndrome severity.ConclusionsNew morbidity was common after pediatric acute respiratory distress syndrome and appears to be intermediate phenotype between survival without morbidity and death, making it a useful metric in future interventional and outcome studies in pediatric acute respiratory distress syndrome.
