Anxiety in Children with Cystic Fibrosis and Their Parents: A Systematic Review

CFTR acts as a potential therapeutic target for attention deficit-hyperactivity disorder

The prevalence of attention deficit-hyperactivity disorder (ADHD) symptoms among individuals with cystic fibrosis (CF) is significantly elevated compared to the general population. Given that the cystic fibrosis transmembrane conductance regulator (CFTR) is the causative gene for cystic fibrosis, this raises the possibility of CFTR playing a crucial role in ADHD. In our study, three heterozygous missense variants (p.E217G, p.F316L, and p.T1220I) were detected in the CFTR gene, which co-segregate with ADHD in two consanguineous families, impacting a total of six family members. Through the utilization of a zebrafish model, it was observed that the cftr knockout line exhibited behaviors akin to hyperactivity, impulsivity, and attention deficits, mirroring the symptoms seen in human ADHD patients. Single-cell RNA sequencing performed on 7 dpf larvae revealed clusters of neuron cells that exhibited sensitivity to cftr, particularly noting a reduction in the number of dopaminergic neuron cells within the cftr mutant fish. Additionally, bulk RNA sequencing and proteomic analysis conducted during the early gastrulation stage demonstrated abnormal expression levels of nervous system genes. Notably, we attempted to employ CFTR modulators Lumacaftor (VX-809) and Ivacaftor (VX-770) to ameliorate the ADHD zebrafish model (generated via per1b mutant), and it was found that enhanced CFTR activity could mitigate ADHD-like behaviors. In summary, our findings shed light on the potential involvement of CFTR in the pathogenesis of ADHD and pave the way for exploring novel diagnostic approaches and therapeutic strategies for ADHD by targeting CFTR.

Mental health and adherence in CF: Self-efficacy and perceived barriers as mediators

BACKGROUND

Symptoms of depression and anxiety can contribute to lower medical treatment adherence. Given that people with cystic fibrosis (PWCF) have higher rates of depressive and anxiety symptoms than those without cystic fibrosis (CF), this study examined factors that mediated the association between mental health and adherence.

METHODS

Participants were 294 adults (M age=25 years) with CF who were enrolled in the Daily Care Check-in Validation Study. Participants completed in-clinic questionnaires that assessed depressive and anxiety symptoms, perceived barriers to self-management, and medication self-efficacy. Medication adherence was measured by pharmacy refill data. Parallel mediation models assessed perceived barriers and medication self-efficacy as mediators between depressive symptoms and adherence, and between anxiety symptoms and adherence.

RESULTS

Perceived interference of barriers to self-management significantly mediated the association between depressive symptoms and adherence (β =-0.005, SE=0.002, 95 % CI [-0.009, -0.001]), and between anxiety symptoms and adherence (β=-0.005, SE=0.003, 95 % CI [-0.008, -0.001]). Additionally, self-efficacy significantly mediated the association between depressive symptoms and adherence (β=-0.004, SE=0.001, 95 % CI [-0.007, -0.002]), and between anxiety symptoms and adherence (β=-0.004, SE=0.001, 95 % CI [-0.007, -0.001]).

CONCLUSIONS

This study found that when PWCF experienced mental health symptoms (either anxiety or depression), they were likely to report more interference from barriers to disease management or experience less medication self-efficacy, which was related to worse adherence. Building self-efficacy around taking medications may reduce the impact that mental health symptoms have on adherence. Care teams should also work with PWCF to minimize the impact of barriers on daily therapies.

The Effectiveness of a Parent Empowerment Intervention for Caregivers of Children with Cystic Fibrosis: A Randomized Controlled Trial

This paper focused on the effectiveness of a parent empowerment intervention based on nursing education (PEINE). This study examined whether the intervention improved the quality of life of children with cystic fibrosis (CF) and improved their caregivers learn about the disease and develop problem-solving and coping skills. This randomized-controlled trial used a pretest-posttest parallel-group research design. The sample consisted of 48 parents (caregivers) of children with CF. Participants were randomly assigned to an intervention (n = 24) and a control group (n = 24). The intervention group received PEINE and standard care and treatment for ten weeks. The control group received standard care and treatment. Data were collected using a Disease Information Survey (DIS), the Ways of Coping Inventory (WCI), the Problem-Solving Inventory (PSI), and the Cystic Fibrosis Questionnaire (CFQ-R). After the intervention, the intervention group DIS scores (d: 1,627 [CI: 0.934,2.305], had more correct answers than the control group. Nursing interventions were effective (p < .001). There was no significant difference in the mean pretest-posttest PSI scores (d: 0.378 [CI: -0.221-0.972], posttest WCI scores (d: 0.239 [CI:-0.356-0.831]) between the intervention and control groups (p>.05). There was a significant difference in the mean posttest CFQ-R scores between the intervention and control groups (d: 1.363 [CI: l.698, 2.015]);(p < .001). PEINE increased the intervention group participants develop disease-management skills. However, the increase in their PSI and WCI scores was statistically insignificant. PEINE also increased the quality of life of children with CF. Parents of children followed in pediatric pulmonary diseases participated in the study. Parents were informed during outpatient clinic visits. After the first meeting, the children and parents who voluntarily agreed to participate in the research were contacted by phone. The outpatient nurse assisted in communicating with children and parents.

Standards for the care of people with cystic fibrosis (CF); recognising and addressing CF health issues

This is the third in a series of four papers updating the European Cystic Fibrosis Society (ECFS) standards for the care of people with CF. This paper focuses on recognising and addressing CF health issues. The guidance was produced with wide stakeholder engagement, including people from the CF community, using an evidence-based framework. Authors contributed sections, and summary statements which were reviewed by a Delphi consultation. Monitoring and treating airway infection, inflammation and pulmonary exacerbations remains important, despite the widespread availability of CFTR modulators and their accompanying health improvements. Extrapulmonary CF-specific health issues persist, such as diabetes, liver disease, bone disease, stones and other renal issues, and intestinal obstruction. These health issues require multidisciplinary care with input from the relevant specialists. Cancer is more common in people with CF compared to the general population, and requires regular screening. The CF life journey requires mental and emotional adaptation to psychosocial and physical challenges, with support from the CF team and the CF psychologist. This is particularly important when life gets challenging, with disease progression requiring increased treatments, breathing support and potentially transplantation. Planning for end of life remains a necessary aspect of care and should be discussed openly, honestly, with sensitivity and compassion for the person with CF and their family. CF teams should proactively recognise and address CF-specific health issues, and support mental and emotional wellbeing while accompanying people with CF and their families on their life journey.

Aiming to Improve Equity in Pulmonary Health: Cystic Fibrosis

This review summarizes the evidence of health disparities in cystic fibrosis (CF), an autosomal recessive genetic disorder with substantial variation in disease progression and outcomes. We review disparities by race, ethnicity, socioeconomic status, geographic location, gender identity, or sexual orientation documented in the literature. We outline the mechanisms that generate and perpetuate such disparities across levels and domains of influence and assess the implications of this evidence. We then recommend strategies for improving equity in CF outcomes, drawing on recommendations for the general population and considering approaches specific to people living with CF.

The Weariness of Hoping: Synchronizing Affect While Awaiting Organ Transplantation for Cystic Fibrosis in Germany

We describe the challenges in synchronizing affect during the lengthy lead-up to organ transplantation. Our analysis draws on ethnographic fieldwork in Eastern Germany among medical staff caring for patients with cystic fibrosis, a progressive, genetic illness. Patient and practitioners must together endure an uncertain wait for a donor organ, while simultaneously living and working toward living as well as possible. The organizing affective principle in this setting is hoping, which is a socio-material practice that must be continuously and interactively re-produced. Too little or too much hoping must be managed by adjusting affective intensities. A failure to strike this balance can lead to what we designate as the weariness of hoping.

Burden and risk factors of anxiety disorders among Arabic pediatric population: A systematic review

<b>Aim:</b> In the general population, where 6 to 20% of individuals experience anxiety disorders, children also experience a higher burden of anxiety. We undertook a systematic review In order to examine and summarize the results from studies that estimated the prevalence of anxiety and/or its associated risk factors in the pediatric populations of Arab nations, primarily the gulf countries.<br /> <b>Methods:</b> Any study that focused on the pediatric population and completed in Arab nations to determine the incidence of anxiety and/or its risk factors among children under the age of 18. The review had 13 articles were included.<br /> <b>Results:</b> The results of the systematic review found that there was a wide variation in the prevalence of anxiety among children. At least 30.2% of the children were found to suffer from anxiety and the prevalence could go up to 60% in some countries with a higher prevalence among girls than boys. Associated factors of anxiety were diverse including exposure to environmental tobacco smoke, parenting style, living with parents suffering from mental disorders, school type, and being female.<br /> <b>Conclusion:</b> The findings of the review demonstrate the higher prevalence of anxiety among children as almost at least one-third of children suffer from anxiety in the Gulf countries. The program managers and the respective government of these Arab countries need to devise some strategies and interventions that not only focus on the children but also their environment.

Depression and anxiety prevalence in people with cystic fibrosis and their caregivers: a systematic review and meta-analysis

BACKGROUND

Prevalence of depression and anxiety in people with cystic fibrosis (PwCF) and their caregivers is high, however, results have been inconsistent. This systematic review and meta-analysis aimed to estimate the prevalence of depression and anxiety in PwCF and their caregivers and explore sources of heterogeneity.

METHOD

MEDLINE, EMBASE, CINAHL plus and PsychINFO databases were searched from inception to January 2021. Studies were included if a specific psychometric tool (PT) to assess depression or anxiety (rather than quality of life) was used and did not involve a transitory patient state. Random-effects models were applied due to high anticipated heterogeneity and I2 estimates were calculated. Sources of heterogeneity were explored through subgroup comparisons. The presence of small-study effects was investigated visually using funnel plots and statistically using the Egger test.

RESULTS

A total of 94 articles (48 full-text publications, 46 abstracts) were included. Depression prevalence in adolescents aged 12-18 years (n = 2386), adults (n = 9206) and caregivers (n = 6617) were 18.7% (95% CI 12.8-25.3%, I2 = 89.2%), 27.2% (95% CI 23.6-31%, I2 = 90.4%), and 32.8% (95% CI 27.9-37.9%, I2 = 90.3%), respectively. Anxiety prevalence in adolescents aged 12-18 years (n = 2142) was 26% (95% CI 19.6-33%, I2 = 86.4%), 28.4% (95% CI 25-31.9%, I2 = 85%) for adults (n = 8175), and 38.4% (95% CI 30.8-46.2%, I2 = 94.6%) for caregivers (n = 5931). Prevalence differed by the PT used and study location.

DISCUSSION

This comprehensive analysis found the prevalence of depression and anxiety in PwCF and their caregivers to be high, supporting recommendations for regular screening. Choice of PT significantly influenced prevalence, indicating a need for future studies to identify the optimal PT for each CF population to identify those most at risk.

Health-Related Quality of Life in Adults with Cystic Fibrosis: Familial, Occupational, Social, and Mental Health Predictors

Background: Cystic Fibrosis (CF) adult patients experience daily physical symptoms and disabilities that may impact their quality of life and mental health. Methods: This prospective study aimed to evaluate the relative contribution of the familial, occupational, and social environment, besides that of the main physical and mental health factors, to the quality of life of CF adult patients using the Cystic Fibrosis Questionnaire-Revised (CFQ-R) in a multivariate model. Results: Fifty patients were analyzed (70% of men; median age of 25 years; median body mass index of 21 kg/m²; median FEV1 of 57%). Anxiety and depression scores were negatively associated with 9 of the 12 CFQ-R domains. When controlling for anxiety and depression, FEV1% and BMI were significant positive predictors of several domains of the CFQ-R. All the familial, occupational, and social components analyzed but one (professional training) were predictors of at least one domain of the CFQ-R. Conclusion: Anxiety and depression explained a greater proportion of the variance than physical variables (age, sex, BMI, FEV1%, and exacerbation in the last year) in CF HRQoL. Many familial, occupational, and social components were also specifically and independently predictors of some HRQoL domains. Their screening might help identifying CF patients eligible for specific interventions, focusing on the impaired QoL dimensions.

Eating Disorders and Disordered Eating Behaviors in Cystic Fibrosis: A Neglected Issue

As with the majority of chronic diseases having specific nutrition recommendations, in cystic fibrosis (CF), the emphasis placed on patients regarding their diet and ideal body weight status often increases the risk of developing disordered eating behaviors and by inference, eating disorders (EDs). Body weight appears to be an important concern for patients with CF, with many patients struggling to lose weight. Between sexes, women appear more preoccupied with dieting compared to men, but exhibit a better body image, mainly due to their preference for a lower weight. Several comorbidities appear to change these dynamics, and visibly apparent factors, including scars, ports, and tubes, and the need for supplementary oxygen supply, may also influence body image perception. Disordered eating is usually initiated during a bout of pulmonary infection, with the patient feeling unwell to eat. Regarding the prevalence of EDs, research appears conflicting on whether it is higher among individuals with a CF diagnosis or not. As for comorbidities, anxiety and depression consist of the most common psychiatric diagnoses in CF, also greatly prevalent in EDs. Despite the plethora of studies, non-specific CF tools, small samples, and lack of data regarding important outcomes, including lung health, indicate the need for more research.

COVID-19: Impact, experiences, and support needs of children and young adults with cystic fibrosis and parents

BACKGROUND

Little is known about the impact of COVID-19 and the United Kingdom's (UK) national shielding advice on people with cystic fibrosis (CF) and their families. This study explored the experiences and support needs of children and young adults (CYAs) with CF, and parents who have a child with CF, during the COVID-19 pandemic.

METHODS

CYAs with CF and parents of CYAs with CF completed a UK wide online survey with open and closed questions exploring experiences, information and support needs and decision-making processes. Qualitative thematic content analysis and descriptive quantitative analyses were undertaken.

RESULTS

CYAs aged 10-30 years (n = 99) and parents of CYAs aged 0-34 years (n = 145) responded. Parents (72.7%) and CYAs (50.0%) worried about the virus, and both were vigilant for virus symptoms (82.7% and 79.7%). Over three-quarters of CYAs were worried about their own health if they caught the virus. CYAs worried about feeling more isolated during the virus (64.9%). Qualitative findings reported the following themes: (1) Disruption-caused by isolation, (2) impact on psychological wellbeing, (3) safety of shielding, and (4) healthcare and treatment provision-changes to care, access and support.

CONCLUSIONS

The impact of COVID-19 and UK shielding advice to have no contact with anyone outside the household caused disruption to the lives and routines of individuals in relation to work, education, social lives, relationships, CF management routines and support. Parents and CYAs highlighted the need for clear, up-to-date and tailored advice on individualized risks and shielding.
