Predictive factors for premature birth and respiratory exacerbation in pregnancies of women with cystic fibrosis

Abstract Objective: In this present study, the authors evaluated the predictive factors for adverse maternal-fetal outcomes in pregnancies of women with cystic fibrosis (CF). Patients were followed up by a referral center for adults in southern Brazil. Methods: This is a retrospective cohort study that used data from electronic medical records regarding pregnancies of women diagnosed with CF. Results: The study included 39 pregnancies related to 20 different women. The main adverse outcomes were high prevalence rates of premature birth (38.5%) and maternal respiratory exacerbation (84.6%). Lower body mass index (BMI) values (< 20.8) and younger ages of CF diagnosis increased the risk of premature birth. The presence of methicillin-resistant and absence of methicillin-sensitive Staphylococcus aureus, as well as a younger age of diagnosis, increased the risk of maternal respiratory exacerbation during pregnancy. Conclusions: Conception in women with CF is often associated with maternal and fetal complications. Continuous monitoring by a multidisciplinary team should emphasize appropriate nutritional status, investigation of bacterial colonization, and immediate attention to respiratory exacerbations.

Physical activity and quality of life of children and adolescents with cystic fibrosis: a cross-sectional study / Atividade física e qualidade de vida de crianças e adolescentes com fibrose cística: um estudo transversal

Abstract Introduction: Regular physical activity (PA) is part of outpatient care offered to most people with cystic fibrosis (CF). Objective: To determine the frequency of the self-reported PA and, secondarily evaluate associations between PA with clinical variables and health-related quality of life (HRQoL) in pediatric and adolescent CF subjects. Method: In this cross-sectional study, subjects between 6 and 17 years of age with a confirmed diagnosis of CF were recruited in the outpatient clinic. The subjects answered questions about the practices of PA, HRQoL questionnaire and clinical variables were collected. Subjects were classified into two groups according to weekly PA practice: PA performed ≥ 3 times/week and performed PA ≤ 2 times/week. Results: 66 subjects completed the study, 72.7% (n=48) had PA ≥ 3 times/week and 27.2% (n=18) had PA ≤ 2 times/week. Only twelve children (18,2%) reached the recommendations of the World Health Organization (WHO) to practice moderate to vigorous physical activities daily. The mean age of the subjects evaluated was 12.3 ± 3.2 years, forced expiratory volume in one second 90 ± 24.1% and forced vital capacity 95 ± 20.4%. The group that performed PA ≥ 3 times/week had a better clinical score (p=0.033), a lower number of hospitalizations in the year (p=0.002), a lower number of days hospitalized in the last year (p=0.020) and better score for the physical (p=0.003) and emotion (p=0.048) domains in HRQoL questionnaire. Conclusion: This study concluded that most subjects did not reach the WHO recommendations for the practice of PA. However, individuals who practice PA at least 3 times/week have better HRQoL, clinical score and fewer hospitalizations.

Resumo Introdução: A atividade física regular (AF) faz parte do tratamento ambulatorial oferecido à maioria das pessoas com fibrose cística (FC). Objetivo: Determinar a frequência da AF autorreferida e secundariamente avaliar as associações entre AF e variáveis clínicas e de qualidade de vida relacionada à saúde (QVRS) em crianças e adolescentes com FC. Método: Neste estudo transversal, indivíduos entre 6 e 17 anos com diagnóstico confirmado de FC foram recrutados no ambulatório. Os sujeitos responderam perguntas sobre as práticas de AF, questionário de QVRS e variáveis clínicas. Os indivíduos foram classificados em dois grupos de acordo com a prática semanal de AF: AF realizada ≥3 vezes/semana e AF≤2 vezes/semana. Resultados: 66 indivíduos completaram o estudo, 72,7% (n=48) tinham AF ≥ 3 vezes/semana e 27,2% (n=18) tinham AF ≤ 2 vezes/semana. Apenas doze crianças (18,2%) alcançaram as recomendações da Organização Mundial da Saúde (OMS) para praticar diariamente atividades físicas moderadas a vigorosas. A média de idade dos sujeitos avaliados foi de 12,3 ± 3,2 anos, volume expiratório forçado no primeiro segundo 90 ± 24,1% e capacidade vital forçada 95 ± 20,4%. O grupo que realizou AF ≥ 3 vezes/semana apresentou melhor escore clínico (p=0,033), menor número de internações no ano (p=0,002), menor número de dias hospitalizados no último ano (p=0,020) e melhor escore para os domínios físico (p=0,003) e emoção (p=0,048) no questionário de QVRS. Conclusão: Este estudo concluiu que a maioria dos indivíduos não alcançou as recomendações da OMS para a prática de AF. No entanto, indivíduos que praticam AF pelo menos 3 vezes/semana apresentam melhor QVRS, escore clínico e menos hospitalizações.

Adherence to inhalation therapy and quality of life in children with cystic fibrosis: a cross-sectional study

Introduction: Inhalation therapy is a crucial part of the cystic fibrosis (CF) treatment regimen. Drugs that assist in mucociliary clearance and inhaled antibiotics are used by most patients. Methods: This is a cross-sectional study where patients with CF and their caregivers answered questionnaires regarding their adherence to inhalation therapy and QoL. Demographic, spirometric, and bacteriological data, as well as S-K scores and hospitalization frequencies were also collected. Results: We included 66 patients in this study; participants had a mean age of 12.3 years and Z-scores of -1.4 for forced expiratory volume in 1 second and 48.6 for body mass index. Patients were divided into 2 groups according to their self-reported adherence to inhalation therapy: high adherence (n = 46) and moderate/low adherence (n = 20). When comparing both groups, there was no statistically significant differences in age, sex, family income, and S-K score (p > 0.05). The high-adherence group had had shorter hospitalization periods in the previous year (p = 0.016) and presented better scores in the following domains of the QoL questionnaire: emotion (p = 0.006), eating (p = 0.041), treatment burden (p = 0.001), health perception (p = 0.001), and social (p = 0.046). Conclusions: A low self-reported adherence to inhalation therapy recommendations was associated with longer hospitalizations in the previous year and with a decrease in QoL in pediatric patients with CF.

Respiratory therapy: a problem among children and adolescents with cystic fibrosis / Fisioterapia respiratória: um problema de crianças e adolescentes com fibrose cística

Objective : To evaluate the level of self-reported adherence to physical therapy recommendations in pediatric patients (6-17 years) with cystic fibrosis (CF) and to ascertain whether the different levels of adherence correlate with pulmonary function, clinical aspects, and quality of life. Methods : This was a cross-sectional study. The patients and their legal guardians completed a questionnaire regarding adherence to physical therapy recommendations and a CF quality of life questionnaire. We collected demographic, spirometric, and bacteriological data, as well as recording the frequency of hospitalizations and Shwachman-Kulczycki (S-K) clinical scores. Results : We included 66 patients in the study. Mean age, FEV1 (% of predicted), and BMI were 12.2 ± 3.2 years, 90 ± 24%, and 18.3 ± 2.5 kg/m2, respectively. The patients were divided into two groups: high-adherence (n = 39) and moderate/poor-adherence (n = 27). No statistically significant differences were found between the groups regarding age, gender, family income, and total S-K clinical scores. There were statistically significant differences between the high-adherence group and the moderate/poor-adherence group, the latter showing lower scores for the "radiological findings" domain of the S-K clinical score (p = 0.030), a greater number of hospitalizations (p = 0.004), and more days of hospitalization in the last year (p = 0.012), as well as lower scores for the quality of life questionnaire domains emotion (p = 0.002), physical (p = 0.019), treatment burden (p < 0.001), health perceptions (p = 0.036), social (p = 0.039), and respiratory (p = 0.048). Conclusions : Low self-reported adherence to physical therapy recommendations was associated with worse radiological findings, a greater number of hospitalizations, and decreased quality of life in pediatric CF patients.

Objetivo : Avaliar o grau de adesão autorrelatada às recomendações fisioterapêuticas em pacientes pediátricos (6-17 anos) com fibrose cística (FC) e determinar se os diferentes níveis de adesão se correlacionam com a função pulmonar, aspectos clínicos e qualidade de vida. Métodos : Estudo transversal no qual os pacientes e responsáveis responderam um questionário sobre a adesão à fisioterapia recomendada e um questionário da qualidade de vida em FC. Foram coletados dados demográficos, espirométricos e bacteriológicos, assim como a frequência de internações e resultados do escore clínico de Shwachman-Kulczycki (S-K). Resultados : Participaram 66 pacientes. As médias de idade, VEF1 (em % do previsto) e IMC foram, respectivamente, 12,2 ± 3,2 anos, 90 ± 24% e 18,3 ± 2,5 kg/m2. Os pacientes foram divididos em dois grupos: alta adesão (n = 39) e moderada/baixa adesão (n = 27). Não houve diferenças estatisticamente significativas para idade, sexo, renda familiar e escore clínico de S-K total na comparação dos dois grupos. Houve diferenças estatisticamente significativas entre os grupos alta adesão e moderada/baixa adesão, este último mostrando valores significativamente menores para o domínio "achados radiológicos" do escore clínico de S-K apresentou (p = 0,030), um maior número de hospitalizações (p = 0,004) e de dias de internação no último ano (p = 0,012), assim como menores escores para os seguintes domínios do questionário de qualidade de vida: emocional (p = 0,002), físico (p = 0,019), tratamento (p < 0,001), saúde (p = 0,036), social (p = 0,039) e respiratório (p = 0,048). Conclusões : A baixa adesão autorrelatada às recomendações fisioterapêuticas associou-se com piores achados radiológicos, maior número de hospitalizações e diminuição da qualidade de vida em pacientes pediátricos com FC.
