Development of depression in survivors of childhood and adolescent cancer: a multi-level life course conceptual framework

A life course approach to asthma and wheezing among young children caused by ozone: A prospective birth cohort in northern China

BACKGROUND

Given differences in vulnerability of children in early life, a life course approach to asthma and wheezing (AW) in young children caused by ozone (O₃) is not fully understood.

METHODS

We conducted a birth cohort in Jinan, China from 2018 to 2021 to elucidate the onset model of childhood AW due to O₃ exposure. An inverse distance weighted model was used for individual exposure assessment. The time-dependent Cox proportional-hazard model and logistic model were used to investigate the effects of O₃ exposure on AW. Principal component analysis, interaction analysis, and distributed lag model were used to analyze the life course approach.

RESULTS

The cumulative incidence rate for AW among 6501 children aged 2 was 1.4%. A high level of O₃ was related to AW (HR: 2.10, 95% CI: 1.31, 3.37). Only O₃ exposure after birth was associated with AW, with an OR of 1.82 (1.08, 3.12), after adjusting for the effect before birth. Furthermore, adjusting for other air pollutants, the HR for the individual effect of high O₃ exposure on AW was 2.44 (1.53, 3.89). Interestingly, P values for interactions for O₃ and the principal components of other pollutants, as well as the characteristic variable of open windows were less than 0.1. Moreover, an increase in the IQR of O₃ exposure at the 31st to 37th weeks before birth and the 1st to 105th weeks after birth was associated with an increase in the HRs for AW.

CONCLUSIONS

High-level of O₃ exposure after birth could lead to AW among young children. Importantly, the AW onset model may include the risk factors accumulation and the sensitive period model. Specifically, there are two sensitive windows in early life, and the correlated insults between the high level of O₃ and other pollutants as well as open windows in the asthma-inducing effect.

Birth Characteristics and Risk of Pediatric Thyroid Cancer: A Population-Based Record-Linkage Study in California

Background: Incidence rates of thyroid cancer in children and young adults (age 0-19 years) have nearly doubled over a recent 15-year period in the United States. Children with thyroid cancer may require long-term therapy and surveillance and are at greater risk for second primary malignancies. High-dose exposure to ionizing radiation is the only known nongenetic risk factor; the vast majority of cases have an unknown etiology. Methods: We conducted a population-based nested case-control study to evaluate the relationship between a range of birth characteristics and the risk of pediatric thyroid cancer. Using linked birth records and cancer registry data from California, we included 1012 cases who were diagnosed with first primary thyroid cancer at the age of 0-19 years from 1988 to 2015 and 50,600 birth-year matched controls (1:50 case to control ratio). We estimated adjusted odds ratios (OR) and 95% confidence intervals (CI) by using multivariable logistic regression models applied to the full population and stratified by thyroid cancer subtypes (papillary and follicular), race/ethnicity (white and Hispanic), and age at diagnosis (0-14 and 15-19 years). Results: Hispanic ethnicity (OR: 1.20 [CI 1.01-1.42]), higher birth weight (OR: 1.11 [CI 1.04-1.18] per 500g), and higher maternal education (13-15 years OR: 1.35 [CI 1.09-1.68], 16+ years OR: 1.35 [CI 1.07-1.71]) were associated with an increased risk of pediatric thyroid cancer, while male sex (OR: 0.21 [CI 0.18-0.25]) and higher birth order (third or higher OR: 0.81 [CI 0.68-0.98]) were associated with a decreased risk. Some heterogeneity was observed across subtype, most notably an elevated OR with higher birth order for follicular thyroid cancer, in contrast to the reduced risk for this category among papillary thyroid cancer cases (p-value for interaction = 0.01). Hispanic ethnicity was a risk factor for papillary, but not follicular thyroid cancer (p-value for interaction = 0.07). Conclusions: In this population-based study of birth characteristics and pediatric thyroid cancer, we identified several important risk factors for pediatric thyroid cancer, including female sex, Hispanic ethnicity, higher birth weight, higher maternal educational attainment, and lower birth order. Our data provide new areas for replication and investigation of biological mechanisms for this poorly understood malignancy.

Impact of Endometriosis on Life-Course Potential: A Narrative Review

Endometriosis may exert a profound negative influence on the lives of individuals with the disorder, adversely affecting quality of life, participation in daily and social activities, physical and sexual functioning, relationships, educational and work productivity, mental health, and well-being. Over the course of a lifetime, these daily challenges may translate into limitations in achieving life goals such as pursuing or completing educational opportunities; making career choices or advancing in a chosen career; forming stable, fulfilling relationships; or starting a family, all of which ultimately alter one's life trajectory. The potential for endometriosis to impact the life course is considerable, as symptom onset generally occurs at a time of life (menarche through menopause, adolescence through middle age) when multiple life-changing and trajectory-defining decisions are made. Using a life-course approach, we examine how the known effects of endometriosis on life-domain satisfaction may impact health and well-being across the life course of affected individuals. We provide a quasi-systematic, narrative review of the literature as well as expert opinion on recommendations for clinical management and future research directions.

"Living life as if I never had cancer": A study of the meaning of living well in adolescents and young adults who have experienced cancer

BACKGROUND

Cancer diagnoses pose challenges to adolescents' and young adults' (AYA) physical, mental, and emotional health, and developmental tasks. In order for AYAs, caregivers, clinicians, and other collaborators to optimize health outcomes (coproduction of health), understanding what living well means for AYAs who have experienced cancer is necessary. The objective was to develop an empirical definition of "living well" for AYAs who have experienced cancer to broadly understand AYA values and priorities. This definition may ultimately guide future conversations between caregivers and AYAs, eliciting thorough, personal definitions of living well from individual AYAs. Such conversations may enhance AYA participation in coproducing their health.

PROCEDURE

Qualitative analysis using a phenomenological approach of N = 30 structured Respecting Choices interviews conducted with AYAs (14-21 years; mean 84.2 [SD 69] months postcancer diagnosis with 21% on active treatment) from four tertiary pediatric hospitals in the context of a primary study of a pediatric advance care planning intervention trial.

RESULTS

AYAs who have experienced cancer conceptualized "living well" as maintaining physical, mental, and emotional health, as well as engaging in purposeful, age-appropriate activities with people important to them. Living well had three components: living mindfully, living an identity as a healthy AYA, and spending time with friends and family.

CONCLUSIONS

Conversations with AYAs who have experienced cancer elicited rich, complex concepts of "living well." Provider initiation of discussions about living well may facilitate personalized goals of care conversations. This study may serve as the basis to design and prototype future clinical interventions to enhance AYA engagement.

Risk factors for suicidal ideation in a large, registry-based sample of adult long-term childhood cancer survivors

INTRODUCTION

Long-term childhood cancer survivors (CCS) are at risk for physical and psychosocial late effects. Previous research has attested to increased rates of suicidal ideation (SI) in CCS, an especially dangerous indicator of distress. However, little was known about risk factors of SI among CCS which go beyond illness- and treatment related variables.

METHODS

A registry-based sample of 916 adult long-term CCS (M_age=34.58 years [SD=5.53], M_{age at diagnosis}=6.15 years [SD=4.28]) underwent medical assessments and filled out questionnaires. We conducted a linear regression analysis on SI, testing predictors of different areas: sociodemographic, social, physical health and health behavior, and psychological distress symptoms.

RESULTS

SI was reported by 73 (8.0%) CCS and previous suicide attempts were reported by 26 (2.8%) CCS. SI was most closely related to social and psychological factors, i.e. to concurrent distress symptoms (depression, anxiety, social phobia), previous suicide attempts, current loneliness, and the present living situation.

LIMITATIONS

SI and previous suicide attempts were assessed using short self-report instruments. The cross-sectional study design does not allow for causal inferences.

CONCLUSIONS

Long-term CCS are a previously understudied, vulnerable group. Decades after having survived cancer, a considerable percentage is affected by (recurrent) SI. CCS' risk for SI is likely shaped by individual medical and psychological history, and by the current social environment and psychological comorbidities. There is a need for more interdisciplinary research and for screening efforts which take account of these factors. Interventions reducing CCS' risk of suicide should foster social integration and counteract current stressors.

What's past is prologue: Recalled parenting styles are associated with childhood cancer survivors' mental health outcomes more than 25 years after diagnosis

BACKGROUND

With the increased survival rates of childhood cancer, long-term survivors' well-being over the life span has come into focus. A better understanding of the determinants of childhood cancer survivors' (CCS) mental health outcomes contributes to the identification of vulnerable individuals as well as to the development of evidence-based prevention and intervention efforts. It has been noted that psychosocial factors such as parental rearing behavior shape individual differences in mental health. There is also evidence that parents show altered parenting behavior in the face of childhood cancer, e. g. that they express more emotional support, but also more worries. However, little is known about the relevance of different parenting styles for CCS' mental health decades after diagnosis and treatment.

METHODS

We examined the associations of recalled parenting styles and disease-related factors with lifetime diagnoses of depression and anxiety disorders in a German, registry-based sample of adult CCS (N = 948, 44.50% women) with survival times >25 years. We conducted logistic regression analyses of lifetime diagnoses of depression and anxiety disorders, respectively, on dimensions of recalled parental rearing behavior (measured with a validated German short version of the EMBU) controlling for relevant adjustment variables such as the presence of physical illnesses.

RESULTS

Recalled parenting styles of both parents had statistically relevant associations with CCS' lifetime depression and anxiety diagnoses. Maternal emotional warmth was related to fewer lifetime diagnoses of depression and fewer lifetime diagnoses of anxiety. Memories of paternal control and overprotection were positively associated with lifetime diagnoses of anxiety.

CONCLUSION

The results indicate that mental representations of one's caregivers are associated with psychological long-term outcomes. Thus, medical professionals should involve the parents and support them in accompanying their child through the difficult times of treatment and survivorship. Interventions aimed at fostering survivors' quality of life should consider the sustained relevance of early relationships.

Internalizing symptoms in AYA survivors of childhood cancer and matched comparisons

OBJECTIVE

As the number of pediatric cancer survivors increases, so does our need to understand behavioral late effects. Prior studies show mixed results, with some noting increased emotional distress and psychiatric diagnoses in cancer survivors and others suggesting resilience. The purpose of our study was to evaluate internalizing symptoms such as anxiety and depression in young adult survivors of childhood cancer compared with matched classroom matched peers.

METHOD

We completed a multisource, cross-sectional examination of internalizing symptoms using a semistructured psychiatric interview with 18-year-olds with a history of pediatric cancer compared with age, race, and gender matched classroom peers who had been identified during the survivor's first year of treatment and their primary caregivers.

RESULTS

Fifty-seven young adult survivors of childhood cancer and 60 comparison peers participated. There were no significant differences between survivors and their peers on the basis of self- or parent-reported depressive or anxiety symptoms or number of psychiatric diagnoses.

CONCLUSIONS

Young adult survivors of childhood cancer and their parents did not report increased rates of anxiety or depression compared with their former classroom peers. Despite experiencing a major life challenge, this group of young adults with cancer did not report more current or past symptoms of internalizing psychopathology.

Depression in Medically Ill Children and Adolescents

Depression risk is 2 to 3 times higher in medically ill youth compared with the general pediatric population. The relationship between medical illness and depression is bidirectional with significant contributions from psychological, developmental, illness-related, familial, and treatment factors. This article discusses the presentation, early identification, evaluation, and management of depression in medically ill youth and identifies specific risk factors and reviewing selected medical illness-specific considerations.

Experiences of Low Mood in Young People With Cancer: A Qualitative Study

Young people with cancer are at increased risk of psychological difficulty; yet there is little research on their experiences of low mood or depressive symptoms to help inform treatment interventions. This qualitative study explored experiences and opinions of low mood or depression in young people with cancer, how their mood related to developmental challenges, strategies used to cope, and how services could improve support. Nineteen young people diagnosed and treated for cancer completed semistructured interviews. Transcripts were thematically analyzed using the framework approach, and analysis produced eight themes, organized into three domains: “A Harder Time of Life,” “Interpersonal Impact of Cancer,” and “Learning to Understand and Describe Low Mood,” Participants interviewed experienced low mood during cancer and predominantly felt “low mood” was a helpful term to describe their emotions. There were similarities and variations in their reported mood compared with clinical depression. The developmental challenges of being a young person with cancer negatively affected their mood. Participants used a variety of different coping strategies to manage these challenges. Young people were clear that they would like others to help them understand negative emotions experienced through cancer are normal to feel and support for low mood to be accessible and available.

The crucial role of primary care providers in the long-term follow-up of adult survivors of childhood cancer

Purpose: The potential physical or psychosocial factors that play a role in the progression of childhood cancer survivors into adulthood are essential in the identification of an effective patient-centred approach to therapy. Despite the presence of guidelines published by the Children’s Oncology Group, knowledge of the long-term health sequelae for the care of survivors is sub-optimal. Here, the pertinent clinical issues that may affect survivors of childhood cancer are outlined for primary care providers (PCPs).

Methods: This literature search identified articles using PubMed, EMBASE Ovid, and the Cochrane Library to determine high-quality, multicenter randomized controlled trials, systematic reviews, meta-analyses, and practice guidelines from December 1998 to December 2018. The keywords of the search were primary care providers; childhood cancer survivors; long-term care and mental health. Guidelines and research using retrospective studies are used to compile evidence to address PCP’s involvement and to describe the factors involved in the adult onset of psychological disorders in survivors of childhood cancer. A focus of this article is to use the literature that evaluated pediatric cancer survivors for at least five years post diagnosis and had received cancer treatment including chemotherapy, radiation, bone marrow transplant, or surgery. Additional research focused on primary care physicians addressing the care of childhood cancer survivors. Here, we aim to provide PCPs and physicians with a critical yet concise update on the recent advancements for this important healthcare topic. This paper presents an overview of previously published reviews and, as such, requires no ethics approval.

Results: Childhood cancer survivors can develop symptoms of depression and suffer from low self-esteem from their diagnosis and treatment regimens. These symptoms can result in functional impairment. Child diagnosis also affects parental health, resulting in the experience of psychological, emotional and traumatic stress. The feeling of helplessness and guilt on parents leads to the potentiation of depression on the child survivor.

Conclusions: Primary care providers, in collaboration with clinician specialists, must be vigilant in providing consistent long-term care. This approach will ensure clear constant communication to help address the challenges faced by the families and survivors as they progress through adulthood.

Implications for cancer survivors: Encouraging primary care providers to become knowledgeable and comfortable in utilizing appropriate resources is achieved through consultation with oncology or psychiatric specialists or with online resources for safer management of childhood cancer survivors. The implications for this patient population would ultimately allow for a more patient-centred approach to therapy.

A Summary of Pediatric Palliative Care Team Structure and Services as Reported by Centers Caring for Children with Cancer

BACKGROUND

Little is known about the composition, availability, integration, communication, perceived barriers, and work load of pediatric palliative care (PPC) providers serving children and adolescents with cancer.

OBJECTIVE

To summarize the structure and services of programs to better understand successes and gaps in implementing palliative care as a standard of care.

METHODS

Cross-sectional online survey about the palliative care domains determined by the Psychosocial Care of Children with Cancer and Their Families Workgroup.

SUBJECTS

A total of 142 surveys were completed with representation from 18 countries and 39 states.

RESULTS

Three-fourths of sites reported having a PPC program available for the pediatric cancer population at their center. Over one-fourth (28%) have been in existence less than five years. Fewer than half of sites (44%) offered 24/7 access to palliative care consultations. Neither hospital-based nor local community hospice services were available for pediatric patients at 24% of responding sites. A specific inpatient PPC unit was available at 8% of sites. Criteria for automatic palliative referrals ("trigger" diagnoses) were reported by 44% respondents. The presence of such "triggers" increased the likelihood of palliative principle introduction 3.41 times (p < 0.003). Six percent of respondents perceived pediatric oncology patients and their families "always" were introduced to palliative care concepts and 17% reported children and families "always" received communication about palliative principles. The most prevalent barriers to palliative care were at the provider level.

DISCUSSION

Children and adolescents with cancer do not yet receive concurrent palliative care as a universal standard.
