Métodos: Este estudo de coorte prospectivo foi realizado com crianças diagnosticadas com COVID-19 internadas em um hospital terciário. A funcionalidade dos pacientes foi avaliada por meio da Escala de Estado Funcional (FSS) pediátrica. Resultados: Foram incluídas no estudo 62 crianças com idade mediana de 3 anos, das quais 70% apresentavam alguma comorbidade antes do diagnóstico de COVID-19. O tempo mediano de internação foi de nove dias, período no qual cinco pacientes vieram a óbito. A avaliação da FSS da amostra mostrou que aproximadamente 55% apresentavam alguma alteração funcional. O grupo de pacientes com os maiores escores na FSS teve um maior tempo de internação (p = 0,016), necessitou de mais oxigenoterapia (p < 0,001), ventilação mecânica (p = 0,001) e internações em unidade de terapia intensiva (p = 0,019) e tinha mais comorbidades cardíacas (p = 0,007), neurológicas (p = 0,003) e respiratórias (p = 0,013). Na análise multivariada, observouse uma associação entre a variável dependente tempo de internação e o escore total da FSS (b = 0,349, p = 0,004) e a presença de comorbidades (b = 0,357, p = 0,004). Conclusões: Verificou-se que mais da metade das crianças internadas devido à C OVID-19 apresentaram algum nível de alteração funcional. Maiores alterações no estado funcional foram associadas à presença de comorbidades prévias, maior necessidade de suporte ventilatório e maior tempo de internação.

This study aimed to evaluate the effects of an early rehabilitation program on lung function, muscle strength, inflammatory markers, and quality of life in adults with CF hospitalized for pulmonary exacerbation. In this randomized controlled trial, 19 patients were included in the intervention group and 15 in the control group. The intervention group underwent an early rehabilitation program for 14 days after admission. All patients underwent spirometry, one-repetition maximum tests (1RM), and the 6-min walk test, and answered the Revised Cystic Fibrosis Questionnaire (CFQ-R) for quality of life and the International Physical Activity Questionnaire. Serum levels of interleukin and tumor necrosis factor alpha (TNF-a) were measured. In the intervention group, there were increases in 1RM biceps (P=0.009), triceps (P=0.005), shoulder abductors (P=0.002), shoulder flexors (P=0.004), hamstrings (Po0.001), and quadriceps values (Po0.001). In addition, there were improvements in CFQ-R-emotion (P=0.002), treatment burden (P=0.002), vitality (P=0.011), and physical scores (P=0.026), and a reduction in the Borg resting fatigue score (P=0.037). The interleukins levels did not change after the intervention. In adult CF patients with pulmonary exacerbation, early hospital rehabilitation had a significant impact on improving resting fatigue, muscle strength, and quality of life.

The aim of this study was to investigate the long-term clinical outcomes of pediatric patients hospitalized with COVID-19. Methods: This was a prospective cohort study involving unvaccinated children and adolescents admitted to a tertiary hospital in southern Brazil with a COVID-19 diagnosis. Data were collected from electronic medical records for one year after the diagnosis. Results: A total of 66 children were included: the median age was 2.9 years; 63.6% were male; and 48.5% were under 2 years of age. Over 70% had at least one comorbidity prior to the COVID-19 diagnosis. During the one-year follow-up period, 59.1% of the children revisited the emergency department, 50% required readmission, and 15.2% died. Younger children with longer hospital stays were found to be at greater risk of readmission. Having cancer and impaired functionality were found to increase the risk of ...

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.

The evaluation of exercise capacity is essential to manage this disease. This study aims to determine the within-subject repeatability of two Six Minute Walk Test (6MWT) in adults with NCFB. NCFB. This cross-sectional observational study included 66 NCFB subjects above 18 years-old (mean of 55 ± 17 years old, 68% women). 73% of the participants presented moderate to severe clinical condition classified by Bronchiectasis Severity Index. It showed that these participants walked 16.6 m less (95%CI 3.8 to 29.4; p < 0.01) in the second 6MWT when compared to the first test, with a within-subject coefficient variation of 9.4% (95%CI 7.2-11.2%) and an intra-test reliability with a high intraclass correlation coefficient of 0.88 (95%CI 0.80-0.93). Bland-Altman plot showed an agreement regarding test repeatability, besides presented a large limit of agreement (− 85 to 116 m). Respiratory rate and systolic blood pressure were significantly higher before starting the second test. In conclusion, 6MWT seems to be reproducible in NCFB subjects and vital sign verification should be attentively checked to assess if the patient is fully recovered to perform a second test, as well as the disease severity score. Other studies on this matter should be conducted with a larger number of participants to confirm the findings of the present study.

(17) Misconceptions, knowledge gaps, and errors regarding ABSTRACT 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, FEV 1 (% of predicted), and BMI were 12.2 ± 3.2 years, 90 ± 24%, and 18.3 ± 2.5 kg/m 2 , 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.
