Effects of combined exercise training with sleep education in older adults with obstructive sleep apnea: protocol for a randomized clinical trial.

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.

Impact of COVID-19 critical illness on functional status, fatigue symptoms, and health-related quality of life one-year after hospital discharge: a systematic review and meta-analysis.

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.

Impact of air pollution on the health of the older adults during physical activity and sedentary behavior: A systematic review.

BACKGROUND: Air pollution, in addition to presenting health risks, can impact the practice of physical activity (PA) and sedentary behavior (SB) in older adults. This study analyzed the impact of air pollution on the health of older adults during PA and SB, through a systematic review. METHODS: A keyword and reference search was performed in PubMed, SCOPUS, SPORTDiscus, and Web of Science. Predetermined selection criteria included study designs: interventions or experiments, retrospective or prospective cohort studies, cross-sectional studies and case-control studies; population: older adults aged 60 years or older; exposures: specific air pollutants (particulate matter (PM), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), black carbon (CN), ultrafine particles (PU), nitrogen oxides (NOx) and biomass fuels) indoors and outdoors; and outcomes: physical activity and/or sedentary behavior. RESULTS: The beneficial effects of PA were attenuated or harmed in 11 studies, showing negative impacts on the health of the older adults, mainly by PM2.5 pollutants. On the other hand, in 10 studies the effects of PA were greater than the negative effects of air pollutants, with a greater frequency in relation to PM2.5. In general, even the articles presenting controversial results suggest that practicing PA in polluted environments is more favorable to the health of older adults than remaining in SB. DISCUSSION AND CONCLUSIONS: On the one hand, air pollution negatively impacted the health of the older adults during PA practices, while on the other hand, PA can mitigate the negative effects of pollutants on the health of older adults during the practices. Evidence shows that practicing PA in environments with low concentrations of pollutants can provide gains and reduce health risks. Remaining in SB in environments with high levels of air pollution worsens the health of older adults.

Did social isolation due to COVID-19 interfere with the quality of sleep and excessive daytime sleepiness in individuals with grade III obesity about to enter a surgical prehabilitation program? An observational study.

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.

Can optoelectronic plethysmography be used to evaluate the thoracoabdominal kinematics of people with morbidly obesity? A systematic review.

BACKGROUND: Optoelectronic Plethysmography (OEP) is an effective method for evaluating thoracoabdominal kinematics. However, little is known about the viability and use the OEP in people with obesity. OBJECTIVE: Summarize information on the use and feasibility of OEP in the assessment of thoracoabdominal kinematics in people with obesity. METHODS: Studies were identified through PubMed, EMBASE, Science Direct, Web of Science and Scopus databases in the February 2021. RESULTS: Six studies met the inclusion criteria. The studies used the OEP to assess abdominal and thoracic mobility in obese people of different BMI, using the default setting. No study reported the impossibility of using OEP in people with obesity. CONCLUSION: Has been shown that it is possible to use the OEP in people with obesity with a BMI of up to 50 kg/m2. More studies are needed to demonstrate the feasibility of the method in people with a BMI greater than this value.

Relationship between handgrip strength, peripheral muscle strength, and respiratory muscle endurance in women with fibromyalgia: a cross-sectional study / Relação entre força de preensão manual, força muscular periférica e resistência muscular respiratória em mulheres com fibromialgia: um estudo transversal

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.

Body mass index, asthma, and respiratory symptoms: a population-based study.

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.

Reliability of the five-repetition sit-to-stand test in patients with chronic obstructive pulmonary disease on domiciliary oxygen therapy.

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.

Translation and cultural adaptation of the King's Brief Interstitial Lung Disease health status questionnaire for use in Brazil.

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.

Is the COPD Assessment Test sensitive for differentiating COPD patients from active smokers and nonsmokers without lung function impairment? A population-based study.

OBJECTIVE: To assess COPD Assessment Test (CAT) scores in adults with and without COPD, as well as to compare the CAT scores for nonsmokers, former smokers, and smokers without COPD with those for patients with COPD. METHODS: This was a cross-sectional population-based study (the Respira Floripa study). The study included adults ≥ 40 years of age residing in the city of Florianópolis, Brazil. A total of 846 households were surveyed. In addition to completing the Respira Floripa questionnaire and the CAT, participants underwent pulmonary function testing. RESULTS: We analyzed data on 1,057 participants (88.1% of the predicted sample size). A functional diagnosis of COPD was made in 92 participants (8.7%). Of those, 72% were unaware that they had COPD. The mean CAT score was higher in the group of COPD patients than in that of individuals without COPD (10.6 [95% CI: 8.8-12.4] vs. 6.6 [95% CI: 6.1-7.0]; p < 0.01). Individual item scores were significantly higher in the patients with COPD than in the individuals without COPD (p < 0.001), the exception being the scores for the items related to sleep (p = 0.13) and energy (p = 0.08). The mean CAT score was higher in the group of COPD patients than in nonsmokers (5.8 [95% CI: 5.3-6.4]) and former smokers (6.4 [95% CI: 5.6-7.2]; p < 0.05). However, there were no significant differences in the mean CAT score between the group of COPD patients and smokers without COPD (9.5 [95% CI: 8.2-10.8]; p > 0.05), the exception being the mean scores for confidence leaving home (p = 0.02). CONCLUSIONS: CAT scores were higher in the group of patients with COPD than in nonsmokers and former smokers without COPD. However, there were no significant differences in CAT scores between COPD patients and smokers without COPD. Smokers with an FEV1/FVC ratio > 0.70 have impaired health status and respiratory symptoms similar to those observed in COPD patients.

Predictors of death in an Intensive Care Unit: contribution to the palliative approach. / Fatores preditores de óbito em Unidade de Terapia Intensiva: contribuição para a abordagem paliativista.

OBJECTIVE: To identify predictors of death in the Intensive Care Unit and relate eligible patients to preferential palliative care. METHOD: A prospective cohort study that evaluated patients hospitalized for more than 24 hours, subdivided into G1 (patients who died) and G2 (patients who were discharged from hospital). For identifying the predictors for death outcome, the intensivist physician was asked the "surprise question" and clinical-demographic data were collected from the patients. Data were analyzed by descriptive/inferential statistics (p<0.05 significance). RESULTS: 170 patients were evaluated. The negative response to the "surprise question" was related to death outcome. A greater possibility of death (p<0.05) was observed among older and more frail patients with less functionality, chronic cardiac and/or renal insufficiencies or acute non-traumatic neurological insult, with multiorgan failure for more than 5 days, and hospitalized for longer. CONCLUSION: Predictors of death were related to a subjective evaluation by the physician, the clinical condition of the patient, underlying diseases, the severity of the acute disease and the evolution of the critical illness. It is suggested that patients with two or more predictive criteria receive preferential palliative care.

RESUMO Objetivo: Avaliar a pontuação obtida no COPD Assessment Test (CAT, Teste de Avaliação da DPOC) por adultos com e sem DPOC, bem como comparar a pontuação obtida no CAT por não fumantes, ex-fumantes e fumantes sem DPOC com a obtida por pacientes com DPOC. Métodos: Estudo populacional transversal (Respira Floripa) do qual participaram adultos com idade ≥ 40 anos, residentes em Florianópolis (SC). Foram investigados 846 domicílios. Além de responderem aos questionários do Respira Floripa e CAT, os participantes realizaram prova de função pulmonar. Resultados: Foram analisados dados referentes a 1.057 participantes (88,1% da amostra prevista). Noventa e dois participantes (8,7%) receberam diagnóstico funcional de DPOC. Destes, 72% não estavam cientes de que tinham DPOC. A média da pontuação no CAT foi maior no grupo de pacientes com DPOC que no de indivíduos sem DPOC [10,6 (IC95%: 8,8-12,4) vs. 6,6 (IC95%: 6,1-7,0); p < 0,01]. A pontuação obtida em cada item do CAT foi significativamente maior nos pacientes com DPOC que nos indivíduos sem DPOC (p < 0,001), à exceção da pontuação obtida nos itens referentes a sono (p = 0,13) e energia (p = 0,08). A média da pontuação no CAT foi maior nos pacientes com DPOC que em não fumantes [5,8 (IC95%: 5,3-6,4)] e ex-fumantes [6,4 (IC95%: 5,6-7,2); p < 0,05]. Entretanto, não houve diferenças significativas entre os pacientes com DPOC e fumantes sem DPOC quanto à média da pontuação no CAT [9,5 (IC95%: 8,2-10,8); p > 0,05], à exceção da média da pontuação no item confiança ao sair de casa (p = 0,02). Conclusões: A pontuação no CAT foi maior no grupo de pacientes com DPOC que em não fumantes e ex-fumantes sem DPOC. Entretanto, não houve diferenças significativas entre pacientes com DPOC e fumantes sem DPOC quanto à pontuação no CAT. Fumantes com relação VEF1/CVF > 0,70 apresentam estado de saúde comprometido e sintomas respiratórios semelhantes aos de pacientes com DPOC.

Fatores preditores de óbito em Unidade de Terapia Intensiva: contribuição para a abordagem paliativista / Factores predictivos de defunción en Unidad de Cuidados Intensivos: aporte para el abordaje paliativista / Predictors of death in an Intensive Care Unit: contribution to the palliative approach

RESUMO Objetivo Identificar preditores de óbito na Unidade de Terapia Intensiva e relacionar pacientes elegíveis para cuidados paliativos preferenciais. Método Coorte prospectivo que avaliou pacientes internados por mais de 24 horas, subdivididos em G1 (pacientes que morreram) e G2 (pacientes com alta hospitalar). Para a identificação dos fatores preditores para o desfecho óbito, foi feita ao médico intensivista a "pergunta-surpresa" e foram coletados dados clínico-demográficos dos pacientes. Os dados foram analisados por estatística descritiva/inferencial (significante p<0,05). Resultados Foram avaliados 170 pacientes. A resposta negativa à "pergunta-surpresa" foi relacionada ao desfecho óbito. Houve maior possibilidade de óbito (p<0,05) entre os pacientes mais velhos, mais frágeis, com menor funcionalidade, com insuficiências cardíaca e/ou renal crônicas ou insulto neurológico agudo não traumático, com falência multiorgânica por mais de 5 dias, internados por mais tempo. Conclusão Preditores de óbito foram relacionados à avaliação subjetiva do médico, à condição clínica do paciente, às doenças de base, à gravidade da doença aguda e à evolução da doença crítica. Sugere-se que pacientes com dois ou mais critérios preditores recebam cuidados paliativos preferenciais.

RESUMEN Objetivo Factores predictivos de defunción en la Unidad de Cuidados Intensivos y relacionar a pacientes elegibles para cuidados paliativos preferentes. Método Cohorte prospectivo que evaluó a pacientes hospitalizados por más de 24 horas, subdivididos en G1 (pacientes que fallecieron) y G2 (pacientes con alta hospitalaria). Para la identificación de los factores predictivos para el resultado defunción, se hizo al médico intensivista la "pregunta sorpresa" y fueron recogidos datos clínico-demográficos de los pacientes. Los datos fueron analizados por estadística descriptiva/inferencial (significante p<;0,05). Resultados Fueron evaluados 170 pacientes. La respuesta negativa a la "pregunta sorpresa" fue relacionada con el resultado defunción. Hubo mayor posibilidad de defunción (p<;0,05) entre los pacientes mayores, más frágiles, con menor funcionalidad, con insuficiencias cardiaca y/o renal crónicas o evento neurológico agudo no traumático, con fallo multiorgánico por más de cinco días, hospitalizados por más tiempo. Conclusión Predictores de defunción fueron relacionados con la evaluación subjetiva del médico, la condición clínica del paciente, las enfermedades de base, la severidad de la enfermedad aguda y la evolución de la enfermedad crítica. Se sugiere que pacientes con dos o más criterios predictivos reciban cuidados paliativos preferentes.

ABSTRACT Objective To identify predictors of death in the Intensive Care Unit and relate eligible patients to preferential palliative care. Method A prospective cohort study that evaluated patients hospitalized for more than 24 hours, subdivided into G1 (patients who died) and G2 (patients who were discharged from hospital). For identifying the predictors for death outcome, the intensivist physician was asked the "surprise question" and clinical-demographic data were collected from the patients. Data were analyzed by descriptive/inferential statistics (p<0.05 significance). Results 170 patients were evaluated. The negative response to the "surprise question" was related to death outcome. A greater possibility of death (p<0.05) was observed among older and more frail patients with less functionality, chronic cardiac and/or renal insufficiencies or acute non-traumatic neurological insult, with multiorgan failure for more than 5 days, and hospitalized for longer. Conclusion Predictors of death were related to a subjective evaluation by the physician, the clinical condition of the patient, underlying diseases, the severity of the acute disease and the evolution of the critical illness. It is suggested that patients with two or more predictive criteria receive preferential palliative care.

Does the COPD assessment test reflect functional status in patients with COPD?

The aim of this study was to investigate whether the chronic obstructive pulmonary disease (COPD) assessment test (CAT) reflects the functional status of patients with COPD. Forty-seven patients underwent anthropometric assessment, spirometry, the 6-minute walk test (6MWT), the Glittre-activity of daily living (ADL) test (TGlittre), the London Chest ADL (LCADL) scale, and the CAT. The total score of the CAT correlated with 6MWT distance, TGlittre time spent, and LCADL%total ( r = -0.56, 0.52, and 0.78, respectively; p < 0.05 for all). There was significant difference in 6MWT distance (490 ± 85.4 m vs. 387 ± 56.8 m), TGlittre time spent (3.67 ± 1.07 min vs. 5.03 ± 1.32 min), and LCADL%total (24.2 ± 3.02% vs. 44.4 ± 13.3%) between the low and high impacts of COPD on health status (respectively, p < 0.05 for all) as well as in the LCADL%total between medium and high impact of COPD on health status (31.3 ± 7.35% vs. 44.4 ± 13.3%; p = 0.001). In conclusion, the CAT reflects the functional status of patients with COPD.

Repercussões da colecistectomia aberta na mobilidade diafragmática e toracoabdominal / Repercussions of open cholecystectomy on diaphragmatic and chest wall mobility

Contextualização: A disfunção diafragmática é sugerida como a principal causa do comprometimento pulmonar e das complicações respiratórias pós-operatórias de pacientes submetidos à colecistectomia. Objetivo: Verificar os efeitos da colecistectomia aberta na mobilidade diafragmática (MD) e na mobilidade toracoabdominal (MT). Método: Estudo analítico, tipo observacional transversal, com amostra de 15 pacientes submetidos à colecistectomia aberta, no Hospital Regional de São José - SC. Os pacientes foram avaliados no pré-operatório e no segundo dia de pós-operatório (2PO). A MD foi analisada pela radiografia torácica na inspiração e expiração máximas. Para mensuração da MT se realizou cirtometria torácica nas regiões axilar, xifoide, basal e umbilical. As frequências respiratória (f) e cardíaca (FC) foram registradas, a intensidade da dor foi avaliada pela escala visual analógica. Na análise dos dados pré e pós-operatório se utilizou o teste de Wilcoxon e a correlação de Pearson (p£0,05). Resultados: Participaram 10 mulheres e 5 homens. O grupo apresentou índice de massa corporal de 30,42±4,48 kg/m2. A média de idade foi de 40,53±9,51 anos (28 a 55 anos). Houve diminuição significativa da MD de 35,91±15,39 cm2 no pré-operatório para 18,56±12,78 cm2 no 2PO (p=0,001). A MT também apresentou redução significativa na medida da cirtometria de todas as regiões (p<0,05). Houve aumento significativo na f, FC e na escala de dor no 2PO (p=0,001, p=0,027 e p=0,016, respectivamente). A diminuição da MD e da MT basal no 2PO apresentou correlação moderada (r=0,533). Conclusões: A colecistectomia aberta reduziu a mobilidade diafragmática e toracoabdominal, evidenciando que pacientes submetidos a esse procedimento cirúrgico apresentam alterações na mecânica respiratória.

Ansiedade e parâmetros funcionais respiratórios de idosos praticantes de dança / Anxiety and functional respiratory parameters of elders dancers

INTRODUÇÃO: A ansiedade é um diagnóstico comum encontrado em idosos e se associa comumente a anormalidades respiratórias. Ligado ao envelhecimento, encontra-se também o sedentarismo, o qual é um importante fator de risco para diversas patologias. A prática de atividade física regular melhora a ansiedade e a condição cardiorrespiratória. Entre os tipos de atividades físicas, a dança destaca-se como uma boa opção para os idosos. OBJETIVO: Descrever os parâmetros respiratórios de idosas praticantes de dança quando comparadas com idosas sedentárias e a influência da prática regular de dança sobre a ansiedade. MATERIAIS E MÉTODOS: Foram avaliadas 18 idosas, divididas em dois grupos: praticantes de dança (grupo G1) e sedentárias (grupo G2). Nos grupos G1e G2, foram aplicados o inventário de ansiedade traço-estado IDATE, a cirtometria, a espirometria e a manovacuometria, além de ser utilizado o questionário de Baecke modificado para idosos, apenas para o grupo G2, a fim de garantir o sedentarismo dos participantes. Foi realizada a estatística descritiva para sintetizar os dados. RESULTADOS: As participantes do grupo G1 apresentaram valores superiores em relação à ansiedade-estado e à pressão expiratória máxima. A cirtometria em nível basal foi maior nas participantes do grupo G1, enquanto em nível xifoide foi maior nas idosas do grupo G2. Todas as participantes obtiveram valores de espirometria dentro da normalidade, sem diferenças entre os grupos. CONCLUSÃO: Observaram-se nas idosas que praticam dança de forma regular menor nível de ansiedade-traço, valores adequados de pressão expiratória máxima e maior valor na cirtometria em nível basal.

INTRODUCTION: Anxiety is a common diagnosis found in elderly and is commonly associated with breathing abnormalities. Associated with aging, it is also found a sedentary lifestyle, which is an important risk factor for diseases. The practice of regular physical activities improves anxiety and cardiorespiratory condition. Between the types of physical activities, dance stands out as a good option for elderly. OBJECTIVE: To describe the influence of regular dance on anxiety and respiratory parameters of elderly dancers when compared with sedentary elders. METHODOLOGY: Were evaluated 18 elders, divided into two groups: dancers (G1 group) and sedentary (G2 group). In G1 and G2 groups it was applied the State-Trait Anxiety Inventory, cirtometry, spirometry and manovacuometry, in addition of the questionnaire of Baecke modified to elders, only for the group G2, in order to ensure the sedentary lifestyle of the participants. Descriptive statistics were used to synthesize the data. RESULTS: The participants in group G1 had higher values in relation of state-anxiety and maximal expiratory pressure. Cirtometry at basal level was higher in participants of group G1, while the xiphoid level was greater in group G2. All participants had spirometry values within the normal ranges, with no differences between groups. CONCLUSION: We observed on elders who practice dance regularly lower level of trait-anxiety, appropriate values of maximal expiratory pressure and higher values on cirtometry at basal level.
