The health-related quality of life in patients with post-COVID-19 after hospitalization: a systematic review.

Symptoms in post-COVID-19 patients who require hospitalization can persist for months, significantly affecting their health-related quality of life (HRQoL). Thus, the present study aimed to discuss the main findings regarding HRQoL in post-COVID-19 patients who required hospitalization. An electronic search was performed in the MEDLINE, EMBASE, CINAHL, Web of Science, LILACS, and Scopus databases, without date and language restrictions, until July 2021. Twenty-four articles were included in the analysis. It seems that HRQoL partially improved soon after hospital discharge, although the negative impact on HRQoL may persist for months. The physical and mental aspects are affected because patients report pain, discomfort, anxiety, and depression. The HRQoL of COVID-19 infected patients was worse than that of uninfected patients. Additionally, HRQoL seemed worse in patients admitted to the intensive care unit than in those who remained in the ward. Improvements in HRQoL after hospital discharge are independent of imaging improvement, and there seems to be no association between HRQoL after hospital discharge and disease severity on hospital admission. Many factors have been identified as determinants of HRQoL, with women and advanced age being the most related to worse HRQOL, followed by the duration of invasive mechanical ventilation and the need for intensive care. Other factors included the presence and number of comorbidities, lower forced vital capacity, high body mass index, smoking history, undergraduate education, and unemployment. In conclusion, these findings may aid in clinical management and should be considered in the aftercare of patients.

Can high-flow nasal cannula reduce the risk of bronchopulmonary dysplasia compared with CPAP in preterm infants? A systematic review and meta-analysis.

BACKGROUND: Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects the premature lung, and to reduce its incidence has been used non-invasive ventilatory support, such as continuous positive airway (CPAP) and high-flow nasal cannula (HFNC). Thus, the objective of this review was to assess whether the use of high flow nasal cannula (HFNC) compared to continuous positive airway pressure (CPAP) decreases the risk of bronchopulmonary dysplasia (BPD) in premature newborns. METHODS: The protocol was registered (Prospero: CRD42019136631) and the search was conducted in the MEDLINE, PEDro, Cochrane Library, CINAHL, Embase, and LILACS databases, and in the clinical trials registries, until July 2020. We included randomized clinical trials comparing HFNC versus CPAP use in premature infants born at less than 37 weeks of gestational age. The main outcome measures were the development of BPD, air leak syndrome, and nasal injury. The methodological quality of the included studies was assessed using the Cochrane risk of bias tool and the GRADE system was used to summarize the evidence recommendations. Meta-analyses were performed using software R. RESULTS: No difference was found between HFNC or CPAP for the risk of BPD (RR: 1.10; 95% CI: 0.90-1.34), air leak syndrome (RR: 1.06; 95% CI: 0.52-2.14), and nasal trauma (RR: 2.00; 95% CI: 0.64-6.25), with a very low level of evidence. CONCLUSION(S): The HFNC showed similar results when compared to CPAP in relation to the risk of BPD, air leak syndrome, and nasal injury. In the literature, no randomized clinical trial has been found with BPD as the primary outcome to support possible outcomes.

Aerobic Capacity of Preterm Children with Very Low Birth Weight at School Age and its Associated Factors.

INTRODUCTION: Respiratory morbidities of preterm infants can cause significant ventilatory impairment thus compromising the aerobic capacity in childhood and adolescence. Therefore, the present study was conducted to evaluate the aerobic capacity in school age preterm children with VLBW and its associated factors. METHODS: A cross-sectional study was conducted among preterm born with VLBW and term children, both aged 6-9 years. An individualized symptom-limited treadmill testing protocol performed aerobic capacity. Measured variables: oxygen pulse (PuO2), percentage of maximum heart rate for age (%HR max), tidal volume/inspiratory capacity ratio (TV/IC), oxygen consumption (VO2) peak, and the ratio of the anaerobic threshold of gas exchange to the predicted percentage of maximum VO2 (VO2@LA/%VO2 max.pred.) were compared between groups. Univariate and multiple linear regression analyses were used to determine the factors associated with aerobic capacity. RESULTS: Thirty-four preterm and 32 term children were included. Similar VO2 peak and the other variables were observed. The development of bronchopulmonary dysplasia (BPD) and being obese/overweight was positively associated with %HR max. The Z-score for height/age and birth weight <1000g was positively associated with PuO2 and peak VO2, and negatively associated with overweight/obesity and female sex. CONCLUSIONS: Aerobic capacity was similar in both groups. Sex, development of BPD, birth weight <1000g and factors related to body growth, such as Z-score for height/age and overweight/obesity, were associated with aerobic capacity in preterm children with VLBW.

Functional capacity during exercise in very-low-birth-weight premature children.

OBJECTIVES: The functional capacity of children born prematurely with very-low-birth weight was compared with that of children born at full-term using the six-minute walk test (6MWT) and the ten-minutes shuttle walk test (10MSWT). The factors affecting walking distance were analyzed. METHODS: A cross-sectional study was conducted with two groups of children aged 6-9 years, matched by sex and age. One group included children born before 37 weeks of gestation weighing <1,500 g and the second group included children born at term. Both groups were submitted to the 6MWT and 10MWST, performed on the same day with an interval of 20 min between tests and the sequence of the tests was randomized, by sealed-envelope technique. Physiological parameters were measured at the beginning and end of each test. The walking distance and factors affecting the walking distance were analyzed. RESULTS: Thirty-seven children born prematurely and 37 born at term were studied. The premature children walked shorter distances in the 6MWT (480.9 ± 80.5 m vs. 518.3 ± 51.8 m, P = 0.010) than term children, and both groups walked similar distances in the 10MSWT (391.5 ± 99.0 m vs. 406.1 ± 79.2 m, P = 0.487). By multiple linear regression analysis, adjusted for confounders, walking distance was associated with height (OR: 3.6) and oxygen dependency at 28 days (OR: -67.7) in the 6MWT (P < 0.001) and with height (OR: 4.9) and oxygen dependency at 28 days (OR: -91.0) in the 10MSWT (P < 0.001). CONCLUSION: In conclusion, this study suggests that children born prematurely with very low birth weight, especially those who had bronchopulmonary dysplasia present limited functional capacity during exercise.

A vibração torácica na fisioterapia respiratória de recém-nascidos causa dor / Does chest vibration during respiratory physiotherapy in neonates cause pain

OBJETIVO: Avaliar a dor em recém-nascidos pré-termo (RNPT) submetidos à fisioterapia respiratória em Unidade de Terapia Intensiva Neonatal. MÉTODOS: Estudo transversal realizado com recém-nascidos prematuros, com indicação de fisioterapia respiratória, em respiração espontânea. Foi aplicada uma técnica de vibração torácica com a mão do terapeuta realizando pequenas oscilações sobre o tórax do paciente e feita a avaliação da frequência cardíaca (FC), frequência respiratória (FR), saturação de pulso de oxigênio (SpO2) e do Sistema de Codificação da Atividade Facial Neonatal (NFCS) para a avaliação da dor antes, durante, imediatamente após (pós-i) e 30 minutos após (pós-30) a vibração no tórax do paciente. Utilizou-se a análise de variância para medidas repetidas para comparação entre as fases, considerando-se significante p<0,05. RESULTADOS: Foram avaliados 13 RNPT, com média de idade gestacional 32,5±2,0 semanas e peso de nascimento 1830±442g. Não foi observada pontuação de dor durante toda a avaliação: pré: 0,5±1,7; durante: 1,5±1,4; pós-i: 1,0±1,3; pós-30: 0±0,3, porém houve diferença estatisticamente significativa entre a fase pós-i e pós-30 na escala NFCS (p<0,05). A FC variou de 120 a 150bpm, a SpO2 permaneceu acima de 95 por cento, e a FR entre 40 e 62rpm, sem diferenças entre os períodos. CONCLUSÕES: Neste grupo de pacientes prematuros internados em UTI neonatal e submetidos à realização de fisioterapia respiratória pela técnica de vibração torácica, não foram observadas alterações fisiológicas e comportamentais de dor.

OBJECTIVE: To observe pain score during chest physiotherapy (CP) in preterm newborns (PTNB) assisted in a Neonatal Intensive Care Unit. METHODS: A cross-sectional study was carried out with PTNB with spontaneous breathing that needed respiratory physiotherapy. A vibration technique was employed, with the hand of the therapist applying oscillations on the patients' thorax. The following variables were assessed: heart rate (HR), respiratory rate (RR) and oxygen saturation (O2Sat), as well as the Neonatal Facial Coding System (NFCS) to analyze pain before (pre), during, just after and 30 minutes after the thoracic vibration technique. Repeated measures analysis of variance was applied to analyze the protocol phases, being significant p<0.05. RESULTS: Thirteen PTNB were assessed. The mean gestational age was 32.5±2.0 weeks, and the birth weight was 1830±442g. No pain was observed during the evaluation: "pre": 0.5±1.7; "during": 1.5±1.4; "just after": 1.0±1.3; "30 min after": 0±0.3, but there was difference in the NFCS scores between the periods "just after" and "30 minutes after" (p<0.05). The HR varied between 120 and 150bpm, O2Sat levels remained over 95 percent, and RR oscillated from 40 to 62mpm, without differences between periods. CONCLUSIONS: Preterm patients spontaneously breathing and submitted to respiratory physiotherapy by thoracic vibration, no evidence of physiological or behavioral pain indicators were observed.
