RESUMO

Background: Obstructive sleep apnea (OSA) is a common disorder that affects approximately 1 billion people worldwide. Advanced age is a significant risk factor. Various treatment options have been explored to reduce the severity of OSA symptoms and physical exercise has emerged as a potential alternative therapy. Therefore, this study aims to investigate the effects of a combined exercise program with sleep education on sleep quality and on the severity of OSA in older adults. Methods: This is a randomized clinical trial with two parallel groups that will involve individuals of both genders aged between 60 and 79 years who have an apnea-hypopnea index (AHI) of more than 15 events per hour and who have not received or are currently undergoing treatment for OSA. Older adults who have engaged in regular exercise in the last six months and individuals with contraindications to exercise will be excluded. The study will assess outcomes related to OSA, including AHI, oxygen desaturation index, minimum and mean oxyhemoglobin saturation, sleep efficiency, sleep latency, and the type of respiratory events. Additionally, sleep quality-related outcomes, daytime sleepiness, physical activity, physical fitness, aerobic capacity, cognitive status, anthropometric measures, and health-related quality of life will be analyzed. Participants will be randomized to two groups: a combined exercise group (involving both resistance and aerobic training) with sleep education, and a control group that will receive only educational recommendations for managing OSA. The intervention will last 12 weeks and will consist of three sessions per week, totaling 36 exercise sessions. Sample size calculation indicates a minimum number of 36 participants. Discussion: If the hypothesis is confirmed, this clinical trial will indicate an effective non-pharmacological intervention for treating OSA in older adults. This intervention could be used as an adjunct to existing approaches designed to improve OSA management. Clinical trail registration: Brazil Clinical Trials Registry (ReBEC), identifier RBR-9hk6pgz.

RESUMO

Purpose: To estimate the prevalence and severity of impairments in functional status, fatigue, and health-related quality of life (HRQoL) among critical COVID-19 survivors one-year after hospital discharge. Methods: A systematic review was conducted following PRISMA statement and registered in PROSPERO (CRD42021258356), with searches in eight databases. Observational studies were selected. The prevalence meta-analysis of abnormalities was performed using random-effects models. Risk of bias was evaluated using the National Heart, Lung, and Blood Institute tool. Results: Twenty studies were included, with data collected between 12 and 13.5 months after hospital discharge and a total of 1828 participants. Of these, 71% were men, and 77.7% were intubated in the intensive care unit (ICU). Impairments and sequelae were identified in varying prevalence and degrees, with greater impact on functional capacity and physical components of fatigue and HRQoL. The prevalence of abnormalities of 32.3% [95% CI 23.9; 41.9] found in the meta-analysis is substantially high. Most studies were classified as having fair and poor quality. Conclusion: Critical COVID-19 survivors experience impairments in functional status, fatigue, and HRQoL to varying degrees one-year after hospital discharge, particularly among patients who stayed in the ICU and on MV for a prolonged period.

Critical COVID-19 survivors exhibit persistent impairments one-year post-discharge.Functional status, fatigue, and health-related quality of life are impaired to varying degrees in approximately one-third of patients.Long-term follow-up care for critical COVID-19 survivors should be prioritized.

RESUMO

Background: The talk test (TT) evaluates the exercise intensity by measuring speech comfort level during aerobic exercise. There are several application protocols available to assess individuals with cardiopulmonary diseases. However, the measurement properties of the TT were not systematically reviewed yet. Methods: A systematic review was developed, registered (CRD420181068930), and reported according to PRISMA Statement. Randomized clinical trials, cross-sectional studies, or series cases were identified through multiple databases and were selected if they presented concomitant speech provocation and an exercise test. Included studies were evaluated based on methodological quality (adapted New Castle-Ottawa Scale), descriptive quality (STROBE Statement), and risk of bias (COSMIN bias risk scale). Results: Ten studies were included. Seven studies presented moderate to high quality and the majority presented good scores according to the STROBE statement. Four hundred and fourteen subjects performed the TT, the majority being patients with coronary artery disease. The test validity was supported by the included studies. Talk Test reliability was considered satisfactory, although only one study presented an adequate reliability analysis. The studies found a correlation between the last positive stage of the TT with the first ventilatory threshold. Workload, oxygen uptake, and heart rate in the last positive stage of the TT were not different from the same parameters related to the first ventilatory threshold. Conclusions: The evidence indicates that the TT is suitable as an alternative tool for the assessment and prescription of exercise in individuals with cardiovascular diseases. The stage when the individual is still able to speak comfortably is suggested as the intensity for aerobic exercise prescription. As there is still no well-defined and fully explored TT protocol, caution is required when interpreting the TT results.

RESUMO

Social isolation (SI) can have negative effects on health, although little is known about the SI consequences on patients with grade III obesity and even less if they are entering a prehabilitation program. OBJECTIVE: the present study analyzes the effects of SI determined by the SARS-CoV-2 pandemic in people with grade III obesity who about to enter a prehabilitation program for bariatric surgery. METHODS: Five patients with grade III obesity who entered a prehabilitation program or which had to be stopped on March 17th, 2020 were evaluated. Excessive daytime sleepiness (EDS) (Epworth Sleepiness Scale - ESS) and sleep quality (SQ) (Pittsburgh Sleep Quality Index - PSQI) were investigated. Data collection took place in the week before the SI government decree and after 30 and 90 days of SI. Statistical analysis was performed using SPSS 20.0 and GraphPad Prism 8.0. The Friedman test was used to verify the difference between the times and a significance level of p < 0.05 was adopted. RESULTS: with SI, EDS improved by 8 points after 30 days and 3 points after 90 days (p < 0.05). The PSQI did not change (p = 0.819). CONCLUSION: the SI improved the EDS of individuals with grade III obesity entering the prehabilitation program, but did not change complementing their SQ. The improvement in EDS may be related to a longer daily sleep time provided by the SI and the lower number of daily work commitments. Measures to improve the SQ of these patients should be considered, including remote forms.

RESUMO

Fibromyalgia (FM) is a disease characterized by generalized and chronic musculoskeletal pain. It is common, the presence of other symptoms such as fatigue, depression, sleep disorders, leading patients to adopt a sedentary lifestyle. Objective: Verify the muscular and respiratory strength of women with FM. Method: Is a cross-sectional study that evaluated 41 women with clinical diagnosis of FM. We analyzed handgrip strength (HS), the strength of the lower limbs, and respiratory muscle endurance using the spirometric maneuver. Results: Patients with FM had a significant reduction in HS, both in the dominant and non-dominant upper limb. Furthermore, peripheral muscle strength in the lower limbs was reduced because on average, participants exceeded the normative five-repetition sit-to-stand test times stipulated for the age groups. Approximately two-thirds of the sample had maximal voluntary ventilation values below the lower limit of normality. We detected inverse and moderate correlation between peripheral muscle strength and HS of non-dominant upper limb (r= −0.472; p= 0.002) and inverse and weak correlation with the HS of dominant upper limb (r= −0.374; p= 0.016); weak correlations between respiratory muscle endurance and HS of dominant upper limb (r= 0.299; p= 0.058), HS of non-dominant upper limb (r= −0.317; p= 0.043), and peripheral muscle strength (r= −0.372, p= 0.017); and strong correlation between HS of dominant upper limb and non-dominant upper limb (r= 0.899; p<0.001). Conclusion: Women with FM present with reduced muscle strength in the upper and lower limbs, as well as lower respiratory muscle resistance.

A Fibromialgia (FM) é uma doença caracterizada por dor musculoesquelética generalizada e crônica. É comum a presença de outros sintomas como fadiga, depressão, distúrbios do sono, levando os pacientes a adotarem um estilo de vida sedentário. Objetivo: Verificar a força muscular e respiratória de mulheres com FM. Método: Estudo transversal que avaliou 41 mulheres com FM. Analisamos a força de preensão manual (FPM), a força de membros inferiores e a resistência dos músculos respiratórios por meio da manobra espirométrica. Resultados: Pacientes com FM tiveram redução significativa da FPM, tanto no membro superior dominante quanto não dominante. A força muscular periférica dos membros inferiores foi reduzida porque, em média, os participantes excederam tempos normativos do teste de levantar e sentar estipulados para as faixas etárias. Aproximadamente dois terços da amostra apresentavam valores máximos de ventilação voluntária abaixo do limite inferior da normalidade. Detectamos correlação inversa e moderada entre força muscular periférica e FPM do membro superior não dominante (r= −0,472; p= 0,002) e correlação inversa e fraca com a FPM do membro superior dominante (r= −0,374; p= 0,016); correlações fracas entre resistência muscular respiratória e FPM do membro superior dominante (r= 0,299; p= 0,058), FPM do membro superior não dominante (r= -0,317; p= 0,043) e força muscular periférica (r= -0,372, p= 0,017); e forte correlação entre FPM de membro superior dominante e membro superior não dominante (r= 0,899; p<0,001). Conclusão: Mulheres com FM apresentam redução da força muscular de membros superiores e inferiores, bem como da resistência dos músculos respiratórios inferiores.

RESUMO

OBJECTIVE: To estimate the prevalence of respiratory symptoms and asthma, according to body mass index (BMI), as well as to evaluate factors associated with physician-diagnosed asthma, in individuals ≥ 40 years of age. METHODS: This was a population-based cross-sectional study conducted in Florianópolis, Brazil, with probability sampling. Data were collected during home visits. Demographic data were collected, as were reports of physician-diagnosed asthma, respiratory symptoms, medications in use, and comorbidities. Anthropometric measurements were taken. Individuals also underwent spirometry before and after bronchodilator administration. Individuals were categorized as being of normal weight (BMI < 25 kg/m2), overweight (25 kg/m2 ≥ BMI < 30 kg/m2), or obese (BMI ≥ 30 kg/m2). RESULTS: A total of 1,026 individuals were evaluated, 274 (26.7%) were of normal weight, 436 (42.5%) were overweight, and 316 (30.8%) were obese. The prevalence of physician-diagnosed asthma was 11.0%. The prevalence of obesity was higher in women (p = 0.03), as it was in respondents with ≤ 4 years of schooling (p < 0.001) or a family income of 3-10 times the national minimum wage. Physician-diagnosed asthma was more common among obese individuals than among those who were overweight and those of normal weight (16.1%, 9.9%, and 8.0%, respectively; p = 0.04), as were dyspnea (35.5%, 22.5%, and 17.9%, respectively; p < 0.001) and wheezing in the last year (25.6%, 11.9%, and 14.6%, respectively; p < 0.001). These results were independent of patient smoking status. In addition, obese individuals were three times more likely to report physician-diagnosed asthma than were those of normal weight (p = 0.005). CONCLUSIONS: A report of physician-diagnosed asthma showed a significant association with being ≥ 40 years of age and with having a BMI ≥ 30 kg/m2. Being obese tripled the chance of physician-diagnosed asthma.

RESUMO

Objectives: To evaluate the reliability and learning effect of the five-repetition sit-to-stand test (5STSt) in severe and very severe chronic obstructive pulmonary disease (COPD) patients on domiciliary oxygen therapy compare the results with those of COPD patients not on such therapy. Methods: Twenty-eight COPD patients were included in the domiciliary oxygen therapy group (DOTG) and 17 in the control group (CG). The participants of the groups were paired by age, sex, body mass index, and lung function. The groups performed two 5STSt (5STSt1 and 5STSt2). Results: In total, 96% of the patients in the DOTG performed better on the second 5STSt (5STSt2) (17.1 ± 4.63s), with an average reduction of 3.87 ± 3.50 s (p < 0.001) and a learning effect of 18.4%. In the CG, 82.3% of patients had better performance on the 5STSt2 (15.06 ± 3.45 s), with an average reduction of 1.38 ± 2.51 s (p = 0.035) and a learning effect of 8.39%. The 5STSt had an ICC of 0.79 (95%CI: 0.02-0.93; p < 0.001) in the DOTG and of 0.89 (95%CI: 0.65-0.96; p < 0.001) in the CG. Conclusion: The 5STSt is reliable in patients with severe and very severe COPD on domiciliary oxygen therapy, with learning effect of nearly 18% in the DOTG. Thus, performing two tests is recommended to achieve the patient´s best performance in this population.

RESUMO Objetivo: Estimar a prevalência de sintomas respiratórios e asma de acordo com o índice de massa corpórea (IMC) em indivíduos com idade ≥ 40 anos e avaliar os fatores associados ao relato de diagnóstico médico de asma. Métodos: Estudo transversal de base populacional realizado no município de Florianópolis (SC), com coleta domiciliar de dados e processo de amostragem probabilístico. Foram coletadas informações demográficas, assim como sobre relato de diagnóstico médico de asma, sintomas respiratórios, medicações em uso e comorbidades. Também foram realizadas medidas antropométricas e espirometria pré- e pós-broncodilatador. O IMC foi categorizado em normal (IMC < 25 kg/m2), sobrepeso (25 kg/m2 ≥ IMC < 30 kg/m2) e obesidade (IMC ≥ 30 kg/m2). Resultados: Foram avaliados 1.026 indivíduos, 274 (26,7%) com IMC normal, 436 (42,5%) com sobrepeso e 316 (30,8%) obesos. A prevalência de diagnóstico médico de asma foi de 11,0%. A prevalência de obesidade foi maior em mulheres (p = 0,03) e em entrevistados com escolaridade < 4 anos (p < 0,001) ou com renda familiar entre 3-10 salários mínimos. Obesos, quando comparados com aqueles com sobrepeso e peso normal, relataram mais frequentemente diagnóstico médico de asma (16,1%, 9,9% e 8,0%, respectivamente; p = 0,04), dispneia (35,5%, 22,5% e 17,9%, respectivamente; p < 0,001) e sibilos no último ano (25,6%, 11,9% e 14,6%, respectivamente; p < 0,001). Esses resultados foram independentes do status tabágico. Além disso, obesos tinham uma chance três vezes maior de relato de diagnóstico médico de asma do que não obesos (p = 0,005). Conclusões: Houve associação significativa entre o relato de diagnóstico médico de asma em indivíduos com idade ≥ 40 anos e IMC ≥ 30 kg/m2. Ser obeso triplicou a chance de diagnóstico médico de asma.

RESUMO

OBJECTIVE: To translate the King's Brief Interstitial Lung Disease (K-BILD) questionnaire to Portuguese and culturally adapt it for use in Brazil. The K-BILD quantifies the health status of patients with ILD. METHODS: The process involved the following steps: authorization from the author of the original (English-language) questionnaire; translation of the questionnaire to Portuguese by three translators, working independently; merging of the translations by a committee of specialists; back-translation of the questionnaire to English; revision and readjustment of the back-translation by the committee of specialists; evaluation by the original author; revision of the back-translation; cognitive debriefing (verification of the clarity and acceptability of the Portuguese-language version in the target population-i.e., patients with ILD); and finalization of the Portuguese-language version. RESULTS: In the cognitive debriefing step, 20 patients with ILD were interviewed. After the interviews, the clarity and acceptability index of each question was ≥ 0.8, which is considered acceptable. CONCLUSIONS: The Portuguese-language version of K-BILD appears to be easily administered to and understood by patients with ILD in Brazil. To our knowledge, this is the only instrument in Brazilian Portuguese that is designed to evaluate the impact that ILD has on the various aspects of the lives of those it affects.
