RESUMO
INTRODUÇÃO: A imobilização prolongada acarreta prejuízos sistêmicos que repercute diretamente em maiores agravos aos pacientes, dentre eles se encontra a redução da VFC, indicativo de maior morbimortalidade clínica. OBJETIVO: Analisar se o tempo de internação hospitalar influencia a modulação autonômica da frequência cardíaca em pacientes pediátricos. METODOLOGIA: Estudo longitudinal, quantitativo e prospectivo, realizado em uma enfermaria pediátrica. A amostra foi de pacientes entre 4 a 11 anos, ambos gêneros, internados dentro das primeiras 48 horas. A coleta iniciou após a assinatura do TCLE pelo responsável, seguida do colhimento dos dados pessoais e clínicos dos pacientes seguida da coleta da VFC, repetida no último dia de internação. A captação da VFC foi realizada pelo monitor Polar RS800CX. Os dados foram transferidos e passados por uma análise matemática no programa Kubios HRV2.2. Por fim, os dados foram tabulados e analisados pelo Microsoft Excel 2013 e software BioEstat® 5.3 respectivamente. RESULTADOS: Os valores lineares no domínio do tempo obtiveram média pré (IRR=644,7 com P=0,42; RMSSD= 46,1 com P=0,017 e SDNN=43,5 com P=0,017) e pós (IRR=656,3; RMSSD=34,8; SDNN=35,38) e no domínio da frequência média pré (LF=41,9 com P=0,013; HF=58,0 com P=0,013; LF/HF=1,03 com P=0,04) e pós (LF=52,2; HF=47,7; LF/HF=3,56). A correlação de Pearson na análise tanto de RMSSD pós x tempo de internação, quanto SDNN pós x tempo de internação demonstraram R=0,55 e R=0,59 respectivamente. CONCLUSÃO: Foi observado que o tempo de internação exerce influência negativa sobre a modulação autonômica da frequência cardíaca em pacientes pediátricos.
INTRODUCTION: Prolonged immobilization causes systemic damage that has a direct impact on greater harm to patients, among which is the reduction in HRV, indicative of greater clinical morbidity and mortality. OBJECTIVE: To analyze whether the length of hospital stay influences the autonomic modulation of heart rate in pediatric patients. METHODOLOGY: Longitudinal, quantitative and prospective study, carried out in a pediatric ward. The sample consisted of patients between 4 and 11 years old, both genders, hospitalized within the first 48 hours. The collection began after the signature of the TCLE by the guardian, followed by the collection of the patients' personal and clinical data, followed by the HRV collection, repeated on the last day of hospitalization. HRV capture was performed by the Polar RS800CX monitor. The data were transferred and passed through a mathematical analysis in the Kubios HRV2.2 program. Finally, data were tabulated and analyzed using Microsoft Excel 2013 and BioEstat® 5.3 software, respectively. RESULTS: Linear values in the time domain obtained mean pre (IRR=644.7 with P=0.42; RMSSD=46.1 with P=0.017 and SDNN=43.5 with P=0.017) and post (IRR=656.3; RMSSD=34.8; SDNN=35.38) and in the pre mean frequency domain (LF=41.9 with P=0.013; HF=58.0 with P=0.013; LF/HF=1,03 with P=0.04) and powders (LF=52.2; HF=47.7; LF/HF=3.56). Pearson's correlation in the analysis of both the RMSSD post x length of stay and the SDNN post x length of stay showed R=0.55 and R=0.59 respectively. CONCLUSION: It was observed that the length of stay has a negative influence on the autonomic modulation of heart rate in pediatric patients.

Although several clinical manifestations of persistent long coronavirus disease (COVID-19) have been documented, their effects on the cardiovascular and autonomic nervous system over the long term remain unclear. Thus, we examined the presence of alterations in cardiac autonomic functioning in individuals with long-term manifestations. The study was conducted from October 2020 to May 2021, and an autonomic assessment was performed to collect heart rate data for the heart rate variability (HRV) analysis. The study participants were divided into the long COVID clinical group, the intragroup, which included patients who were hospitalized, and those who were not hospitalized and were symptomatic for different periods (≤3, >3, ≤6, and >6 months), with and without dyspnoea. The control group, the intergroup, comprised of COVID-free individuals. Our results demonstrated that the long COVID clinical group showed reduced HRV compared with the COVID-19-uninfected control group. Patients aged 23-59 years developed COVID symptoms within 30 days after infection, whose diagnosis was confirmed by serologic or reverse-transcription polymerase chain reaction (swab) tests, were included in the study. A total of 155 patients with long COVID [95 women (61.29%), mean age 43.88 ± 10.88 years and 60 men (38.71%), mean age 43.93 ± 10.11 years] and 94 controls [61 women (64.89%), mean age 40.83 ± 6.31 and 33 men (35.11%), mean age 40.69 ± 6.35 years] were included. The intragroup and intergroup comparisons revealed a reduction in global HRV, increased sympathetic modulation influence, and a decrease in parasympathetic modulation in long COVID. The intragroup showed normal sympathovagal balance, while the intergroup showed reduced sympathovagal balance. Our findings indicate that long COVID leads to sympathetic excitation influence and parasympathetic reduction. The excitation can increase the heart rate and blood pressure and predispose to cardiovascular complications. Short-term HRV analysis showed good reproducibility to verify the cardiac autonomic involvement.
RESUMO
Performing physical exercise during hemodialysis has been debated regarding safety and efficacy for improving life quality for patients with chronic kidney disease (CKD). Thus, we explored the influence of physical exercise during hemodialysis on both autonomic modulation of heart rate and quality of life for patients with CKF in a randomized clinical trial. We randomly allocated participants requiring hemodialysis to an experimental exercise group (EG) and a control no-exercise group (CG) and assessed their quality of life with the Kidney Disease Quality of Life Short Form-KDQOL-SF™ 1.3 and with Polar RS800CX to monitor their heart rate variability (HRV) before and three months after the end of the exercise intervention. EG participants reported a significant increase in their quality of life (p = .05, physical function, physical aspects, pain, emotional well-being, emotional function; p = .03, energy and fatigue) and showed HRV improvement (p = .05, RMSSD, SDNN, and SD2; p = .004, SD1) after three months of exercise. Thus, we recommend supervised physical exercise during hemodialysis for carefully selected patients.

PURPOSE: This study aimed to investigate the effectiveness of different physical therapy protocols on the autonomic modulation of heart rate, time of invasive mechanical ventilation (IMV), and length of hospital stay. METHODS: This was a randomized clinical study with 20 children on IMV in an intensive care unit (ICU), between July 2018 and September 2019. The control group (n = 10) performed the hospital's physical therapy protocol and the experimental group (n = 10) performed the physical therapy protocol based on physical exercise. RESULTS: Higher values of heart rate variability were found in the experimental group, both in individual and intergroup analyses. There was a significant reduction in the time of IMV and ICU stay. CONCLUSION: There was an improvement in heart rate variability, reduced time on mechanical ventilation and length of stay in the ICU in individuals who performed the study protocol.

This blind randomized clinical trial evaluated the effect of CIMT on the functionality and quality of life (QOL) of chronic hemiparetics. Thirty volunteers were divided into two groups: Control (CG) and CIMT (CIMTG); evaluated before and after 12 and 24 intervention sessions. The scales used were: adapted Fugl-Meyer Motor Assessment (FMA), Modified Ashworth, Stroke Specific Quality Of Life (SS-QOL) and the Functional Reach Test (FRT). The scores for all FMA variables in the CIMTG increased until the 24th session, differing from the pre-treatment. In the CG, the scores increased for pain, coordination/ speed and sensitivity. In the FRT there was an increase in the scores in both groups; after the 12th and 24th sessions, the result of the CIMTG was superior to the CG. For the SS-QOL in the CIMTG, the general score and most of the variables increased, as well as in the CG. Muscle tone in CIMTG was lower compared to CG after 24 sessions. Both protocols used in the study were effective, the CIMT protocol showed benefits in recovering the functionality of the paretic upper limb, in the functional range and in reducing muscle tone, with a consequent improvement in quality of life.

BACKGROUND: Prostate cancer leads to worse quality of life due to treatment and consequences of disease; benefits of physical exercise remain unclear on the improvement of quality of life in this population. The aim of this study is to evaluate the effectiveness of physical exercise in improving quality of life in patients with prostate cancer. METHODS: A systematic review and meta-analysis was carried out. For the search of studies, we used electronics databases such as Cochrane Library, MEDLINE via PUBMED, Regional Health Portal, and EMBASE, without language restrictions or year of publication. The descriptors used were as follows: "prostatic neoplasms," "exercise," and "quality of life." The risk analysis of bias in the meta-analysis was based on the Cochrane Collaboration Tool. For statistical analysis, the fixed effects model was used. Randomized controlled trials were included, which had a sample of patients with stage I-IV prostate cancer and that the intervention was aerobic physical exercise (AE) or resistance physical exercise (RE) or combined AE and RE. RESULTS: Five thousand six hundred nineteen studies were identified, but only 12 studies were selected. The quality of life of the patients was measured using instruments (SF 36, EORTC, AQoL-8D, IPSS and FACT-P), which served to divide the studies in groups where they presented the same instrument used. The analysis carried out shows that the quality of life of patients with prostate cancer submitted to aerobic training regimens had a protective effect in relation to the others. CONCLUSION: Most studies show an improvement in the quality of life of patients when they practice physical exercise, perceived by increasing the score of the instrument in question. However, methodological and heterogeneous differences between the studies increase the analysis bias.

BACKGROUND AND PURPOSE: The aim of this study was to investigate the influence of different physiotherapy protocols on heart rate variability (HRV) and hospital length of stay in older adults undergoing coronary artery bypass graft (CABG). METHODS: Randomized controlled trial with allocation and researcher blinding and intention-to-treat analysis. Forty-eight patients undergoing CABG were randomly assigned to a control group (CG), early mobilization group (EMG), or virtual reality group (VRG). CG performed respiratory physiotherapy and metabolic exercises, the EMG performed cycle ergometer exercises and ambulation, and the VRG performed the same activities as the EMG, with the addition of two Nintendo Wii games during 3 postoperative days. The variables of heart rate variability on preoperative and fourth postoperative day, and time of discharge of hospital was analyzed. RESULTS: The VRG presented a shorter hospital length of stay (p = 0.03). The CG showed a decline in HRV from the preoperative period to fourth postoperative day on square root of the mean of the squared differences between successive RR intervals (33.18 ± 9.89-9.74 ± 6.88, p < 0.05), standard deviation of all RR intervals (25.48 ± 7.50-15.23 ± 11.27, p < 0.05), and dispersion of points perpendicular to identity line (28.26 ± 21.6-2.73 ± 1.31, p < 0.05). The EMG and VRG presented a higher cardiac autonomic modulation compared to the CG (p < 0.05), with improved parasympathetic activity. CONCLUSIONS: Different protocols of physiotherapy intervention affected autonomic modulation of the heart rate and hospital length of stay in patients undergoing CABG.

BACKGROUND: Colorectal cancer decrease quality of life, due to treatment and disease, and physical exercise can improve the quality of life of patients with cancer, but it is still uncertain whether physical exercise can improve quality of life in these patients. AIM: To determine if there is an improvement in the quality of life in patients diagnosed with colorectal cancer undergoing physical exercise. METHODS: A systematic literature review was carried out; non-randomized clinical trials of any year were included from PubMed, Embase, Cochrane, and VHL platforms, without specific language delimitation, and analyzed the influence of physical exercise on the quality of life of patients diagnosed with colorectal cancer, and for analysis of bias, the Cochrane Manual for the Development of Systematic Intervention Reviews was used. RESULTS: Four studies were analyzed in full to produce the results; of these, three intervened with unsupervised aerobic exercises and one with semi-supervised aerobic exercises, all used the FACT-C as a questionnaire to assess quality of life, some even used FACT-G and/or SF-12, and only one author found significance values in the variables of physical well-being, emotional well-being, and functional well-being of the questionnaire, compared with the control group. CONCLUSION: There were no significant increases in the quality of life of patients diagnosed with colorectal cancer compared with the control group.

Coronavirus pandemics causes systemic and mainly pulmonary changes. We assessed the prevalence of generalized anxiety disorder (GAD) in pandemic survivors and the general population. Papers indexed by MEDLINE/PubMed, The Cochrane, Embase, Lilacs, Scielo, Psycoinfo, and Pepsic databases were searched to April 2020, using GAD and Coronavirus (CoV) infection as keywords. Sixteen studies with 25,779 participants in eight countries were included. A 46% pooled prevalence of anxiety symptoms (95% CI 33.9-58.2%) was found with significant evidence of between-study heterogeneity (Q = 154953, I2 = 99.99%, p < 0.001). Age and sex were not found to be significant moderators for anxiety symptoms. Intervention programs for anxiety symptoms are highly recommended.

Abstract Introduction: The presence of human T-cell lymphotropic virus type 1 (HTLV-1) associated with neuropathy (myelopathy/tropical spastic paraparesis - HAM/TSP), can generate morphological and functional changes in the respiratory system. As a preventive therapeutic possibility for respiratory dysfunctions, it is expected that the already conceptualized inspiratory muscle training, when performed at home, can be a therapeutic resource that favors adherence to treatment. Objective: To evaluate respiratory muscle strength in patients with HTLV-1 after participating in a home respiratory muscle training protocol under indirect supervision. Method: This was a clinical, longitudinal, prospective, quantitative, and single-center trial approved by the Research Ethics Committee of the State University of Pará, opinion no. 2.695.505 and registered in clinical trials NCT03829709. Six HTLV-1 patients participated in a 5-week home respiratory muscle training protocol lasting 30 minutes daily through a linear load inspiratory muscle trainer. For the characterization of the imposed load, they were submitted to manovacuometry during pre (T0), peri (T3), and post (T5) treatment. Results: Six individuals completed the program, of which 83.33% were female and 16.66% male. With the application of respiratory muscle training, it was possible to achieve a significant increase (p < 0.011) of the maximum inspiratory pressure as shown when comparing T0 (66.8±12.58) to T5 (115.08±31.78). Conclusion: This study identified an increase in inspiratory muscle strength after HTLV-1 patients participated in a home muscle training protocol under indirect supervision.
Resumo Introdução: A presença do vírus linfotrópico de células T humana do tipo 1 (HTLV-1) associado à neuropatia (Paraparesia Espástica Tropical/Mielopatia - PET/MAH) pode gerar alterações morfológicas e funcionais no sistema respiratório. Como possibilidade terapêutica preventiva para disfunções respiratórias, vislumbra-se que o treinamento muscular inspiratório já conceituado, possa a nível domiciliar ser uma ferramenta terapêutica que favoreça a adesão ao tratamento. Objetivo: Avaliar a força muscular respiratória diante de um protocolo de treinamento muscular respiratório domiciliar, sob supervisão indireta em portadores do HTLV- 1. Método: Estudo clínico, longitudinal, prospectivo, quantitativo e de centro único, aprovado pelo Comitê de Ética em Pesquisa da Universidade do Estado do Pará, parecer no. 2.695.505 e registrado no Clinical Trials NCT03829709. Seis pacientes com HTLV-1 participaram de um protocolo de treinamento muscular respiratório domiciliar por 5 semanas com duração de 30 minutos diários por meio de um treinador muscular inspiratório de carga linear. Para a caracterização da carga imposta, os mesmos foram submetidos a manovacuometria, pré (T0), peri (T3) e pós (T5) tratamento. Resultados: Seis indivíduos completaram o programa, dos quais 83.33% eram do sexo feminino e 16.66% do sexo masculino. Com a aplicação do treinamento muscular respiratório foi possível obter um aumento significativo (p < 0,011) da pressão inspiratória máxima ao comparar T0 (66.8±12.58) ao T5 (115.08±31.78). Conclusão: Este estudo identificou um aumento na força muscular inspiratória após pacientes com HTLV-1 participarem de um protocolo de treinamento muscular domiciliar sob supervisão indireta.
