Comparison of Physical Activity and Sedentary Behaviour between Schoolchildren with Cystic Fibrosis and Healthy Controls: A Gender Analysis
The purpose of this study was to examine differences in sports participation and the levels of physical activity (PA) and sedentary behaviour (SB) between schoolchildren with cystic fibrosis (CF) and a healthy control group (CG) taking into account the gender variable. PA and SB were measured with an accelerometer for 7 consecutive days in 44 children (24 girls
Implementation of a gene panel for genetic diagnosis of primary ciliary dyskinesia
Abstract Introduction Primary ciliary dyskinesia (PCD) is characterized by an alteration in the ciliary structure causing difficulty in the clearance of respiratory secretions. Diagnosis is complex and based on a combination of techniques. The objective of this study was to design a gene panel including all known causative genes, and to corroborate their diagnostic utility in a cohort of Spanish patients. Methods This was a multicenter cross-sectional study of patients with a high suspicion of PCD according to European Respiratory Society criteria. We designed a gene panel for massive sequencing using SeqCap EZ capture technology that included 44 genes associated with PCD. Results We includ…
Chronic Respiratory Disease Questionnaire (CRQ-SAS): Analysis of psychometric properties
The Chronic Respiratory Disease Questionnaire Self-Administered Standardized (CRQ-SAS) format is used to assess health-related quality of life in different languages and adult populations, but it has not been validated in adolescents. This study analyzes the psychometric properties of the CRQ-SAS in a sample of adolescent patients with chronic respiratory disease and correlates them to anxiety and depression.In relation to the CRQ-SAS psychometric properties, exploratory and confirmatory factor analyses were done to assess the instrument's reliability and validity. Correlations and multiple linear regressions with the Hospital Anxiety and Depression Scale were done to assess the relation wi…
The disease-specific clinical trial network for primary ciliary dyskinesia: PCD-CTN
Primary ciliary dyskinesia; Rare genetic disorder; Lung diseases Discinesia ciliar primaria; Trastorno genético raro; Enfermedades pulmonares Discinesia ciliar primària; Trastorn genètic rar; Malalties pulmonars Primary ciliary dyskinesia (PCD) is a rare genetic disorder characterised by impaired mucociliary clearance leading to irreversible lung damage. In contrast to other rare lung diseases like cystic fibrosis (CF), there are only few clinical trials and limited evidence-based treatments. Management is mainly based on expert opinions and treatment is challenging due to a wide range of clinical manifestations and disease severity. To improve clinical and translational research and facili…
Implementación de un panel de genes para el diagnóstico genético de la discinesia ciliar primaria
Resumen Introduccion La discinesia ciliar primaria (DCP) es una enfermedad caracterizada por una alteracion en la estructura ciliar que impide el correcto aclaramiento de las secreciones respiratorias. Su diagnostico es complejo y se basa en una combinacion de tecnicas. El objetivo de este estudio fue disenar un panel de genes incluyendo todos los genes causantes conocidos y comprobar su utilidad diagnostica en una cohorte de pacientes espanoles. Metodos Estudio transversal multicentrico de pacientes con sospecha elevada de DCP, aplicando los criterios de la European Respiratory Society. Diseno de un panel de genes para secuenciacion masiva con la tecnologia de captura SeqCap EZ technology,…
Emotional distress in family caregivers of adolescents with bronchial asthma: analysis of its predictors
Adolescents with asthma face problems inherent to this stage in their development, to which the challenges of taking over control of their disease, complying with a daily treatment and regular medical followup are added. Any rejection generated by this may lead to treatment non-adherence and poor asthma control, which brings about problems in family dynamics, made worse by the stress or the emotional distress that this situation causes in caregivers.Identify adjustment profiles and predictors of risk for the well-being of caregivers of pediatric patients with bronchial asthma.Seventy-nine family caregivers of pediatric patients with bronchial asthma. Instruments were used to assess the emot…
Immunofluorescence Analysis as a Diagnostic Tool in a Spanish Cohort of Patients with Suspected Primary Ciliary Dyskinesia
Primary ciliary dyskinesia (PCD) is an autosomal recessive rare disease caused by an alteration of ciliary structure. Immunofluorescence, consisting in the detection of the presence and distribution of cilia proteins in human respiratory cells by fluorescence, has been recently proposed as a technique to improve understanding of disease-causing genes and diagnosis rate in PCD. The objective of this study is to determine the accuracy of a panel of four fluorescently labeled antibodies (DNAH5, DNALI1, GAS8 and RSPH4A or RSPH9) as a PCD diagnostic tool in the absence of transmission electron microscopy analysis. The panel was tested in nasal brushing samples of 74 patients with clinical suspic…
Spanish multicentre study on morbidity and pathogenicity of tracheal bronchus in children.
Tracheal bronchus (TRB) has been generally considered an anatomical variant of the tracheobronchial tree without a precise pathological effect. Its prevalence is estimated to be between 0.2% to 3% of all children undergoing bronchoscopy and scientific information has been limited to case reports or small case series. Our working hypothesis was that TRB could trigger by itself recurrent or persistent respiratory symptoms. The objective of this retrospective and multicentre study of children with a diagnosis of TRB, coming from the main paediatric pulmonology units of Spain, was to determine the anatomical and clinical characteristics, including comorbidities, of TRB in childhood and their im…
Primary ciliary dyskinesia and psychological well-being in adolescence.
Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disease with low prevalence in pediatrics. Health studies have not sufficiently analyzed the role of psychological variables in rare diseases such as PCD. This paper studies the psychological characteristics of a group of pediatric patients diagnosed with PCD compared to their healthy peers. The sample consisted of 48 preadolescents-adolescents, aged 9-18 years (M = 12.96; SD = 2.71), with similar distribution by sex, and 25% of the patients having dyskinesia. Clinical anxiety-depression, self-esteem and psychological well-being were evaluated using questionnaires: the Adolescent Psychological Well-being Scale (BIEPS-J), the Hos…
