ABSTRACT
OBJECTIVE: To grasp the meaning of perinatal palliative care for the multidisciplinary team. METHODS: This is a qualitative study guided by content analysis. The study included 56 health professionals working in maternal and child units of a public university hospital. A semi-structured interview was conducted, which was recorded and subsequently fully transcribed. The collection took place from June 2018 to May 2019. Data were entered and exported to Atlas ti: The Qualitative Date Analysis & Research Software, version 23.1.1.0. RESULTS: Four thematic categories emerged from the data analysis: palliative care and eligible public in the view of professionals; communication between family and team in decision-making; assistance in palliative care; humanized care. CONCLUSIONS: The professionals think of palliative care in Perinatology in a similar way and perceive the difficulties of communication with the family and decision-making. They agree that it is necessary to provide greater support to the family, and to provide comfort measures, either for the non-viable fetus or for the baby eligible for palliative care.

Introduction: Chronic obstructive pulmonary disease is a systemic disease characterized not only by respiratory symptoms but also by physical deconditioning and muscle weakness. One prominent manifestation of this disease is the decline in respiratory muscle strength. Previous studies have linked the genotypes of insulin-like growth factor 1 and 2 (IGF-1 and IGF-2) to muscle weakness in other populations without this disease. However, there is a notable knowledge gap regarding the biological mechanisms underlying respiratory muscle weakness, particularly the role of IGF-1 and IGF-2 genotypes in this pulmonary disease. Therefore, this study aimed to investigate, for the first time, the association between IGF-1 and IGF-2 genotypes with respiratory muscle strength in individuals with chronic obstructive pulmonary disease. In addition, we analyzed the relationship between oxidative stress, chronic inflammation, and vitamin D with respiratory muscle strength. Methods: A cross sectional study with 61 individuals with chronic obstructive pulmonary disease. Polymerase chain reaction of gene polymorphisms IGF-1 (rs35767) and IGF-2 (rs3213221) was analyzed. Other variables, related to oxidative stress, inflammation and Vitamin D were dosed from peripheral blood. Maximal inspiratory and expiratory pressure were measured. Results: The genetic polymorphisms were associated with respiratory muscle strength ( 3.0 and 3.5; = 0.57). Specific genotypes of IGF-1 and IGF-2 presented lower maximal inspiratory and expiratory pressure (<0.05 for all). Oxidative stress, inflammatory biomarkers, and vitamin D were not associated with respiratory muscle strength. Conclusion: The polymorphisms of IGF-1 and IGF-2 displayed stronger correlations with respiratory muscle strength compared to blood biomarkers in patients with chronic obstructive pulmonary disease. Specific genotypes of IGF-1 and IGF-2 were associated with reduced respiratory muscle strength in this population.
Introducción: La enfermedad pulmonar obstructiva crónica es una enfermedad sistémica caracterizada no solo por síntomas respiratorios, sino también por el deterioro físico y la debilidad muscular. Una manifestación destacada de esta enfermedad es el declive en la fuerza de los músculos respiratorios. Estudios previos han vinculado los genotipos de factor de crecimiento insulínico 1 y 2 (IGF-1 e IGF-2) con la debilidad muscular en poblaciones sin esta enfermedad. Sin embargo, existe un vacío de conocimiento con respecto a los mecanismos biológicos subyacentes a la debilidad de los músculos respiratorios, en particular el papel de los genotipos IGF-1 e IGF-2 en esta enfermedad pulmonar. Por lo tanto, este estudio tuvo como objetivo investigar, por primera vez, la asociación de los genotipos IGF-1 e IGF-2 con la fuerza de los músculos respiratorios en individuos con enfermedad pulmonar obstructiva crónica. Además, analizamos la relación entre el estrés oxidativo, la inflamación crónica y la vitamina D con la fuerza de los músculos respiratorios. Métodos: Un estudio transversal con 61 individuos con enfermedad pulmonar obstructiva crónica. Se analizó la reacción en cadena de la polimerasa de los polimorfismos genéticos IGF-1 (rs35767) e IGF-2 (rs3213221). Otras variables relacionadas con el estrés oxidativo, la inflamación y la vitamina D se dosificaron a partir de muestras de sangre periférica. Se midieron las presiones inspiratorias y espiratorias máximas. Resultados: Los polimorfismos genéticos están asociados con la fuerza de los músculos respiratorios (F: 3.0 y 3.5; R2= 0.57). Genotipos específicos de IGF-1 e IGF-2 presentaron bajos valores en las presiones inspiratorias y espiratorias (p<0.05 en todos los casos). El estrés oxidativo, los biomarcadores inflamatorios y la vitamina D no se asociaron con la fuerza de los músculos respiratorios. Conclusión: Los polimorfismos de IGF-1 e IGF-2 mostraron correlaciones más sólidas con la fuerza de los músculos respiratorios en pacientes con enfermedad pulmonar obstructiva crónica en comparación con los biomarcadores sanguíneos. Genotipos específicos de IGF-1 e IGF-2 se asociaron con una disminución de la fuerza de los músculos respiratorios en esta población.

ABSTRACT
Introduction: The impact of pre-sarcopenia, sarcopenia on important clinical and biological outcomes in individuals with Chronic obstructive pulmonary disease (COPD) have not been fully investigated. Objective: To analyze the impact of pre-sarcopenia and sarcopenia on balance, muscle mass, peripheral and respiratory muscle strength and inflammatory and oxidative stress biomarkers in individuals with COPD. Methods: sixty-one patients diagnosed with COPD were included, stratified into three groups: without sarcopenia (n = 33; 69 ± 6 years), with pre-sarcopenia (n = 15; 66 ± 6 years) and with sarcopenia (n = 13; 71 ± 7 years), according to the European Working Group on Sarcopenia in Older People. It was assessed respiratory muscle strength, through maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), handgrip strength (HGS) and body composition analysis with bioimpedance. Inflammatory and oxidative stress biomarkers were analysed from peripheral blood. Results: The prevalence of pre-sarcopenia and sarcopenia in individuals with COPD was 36% and 25%, respectively. Individuals with sarcopenia exhibit inferior muscle mass, peripheral muscle strength, respiratory muscle strength, and balance compared to their counterparts (p<0.05 for all). In addition, individuals with sarcopenia presented lower levels of protein oxidation (p=0.015) and higher levels of interleukin-1ɓ (p=0.035) compared to those without sarcopenia. Individuals with pre-sarcopenia presented lower levels of antioxidant activity (p=0.045) and higher levels of C-reactive protein (p=0.035). Conclusion: Individuals with COPD who have sarcopenia exhibit diminished muscle mass, impaired balance, and reduced peripheral and respiratory muscle strength in comparison to those with pre-sarcopenia or without sarcopenia. In addition, the presence of sarcopenia and pre-sarcopenia is probably linked by biological mechanisms related to systemic inflammation and oxidative stress.(AU)

Background: Although invasive mechanical ventilation (IMV) has contributed to the survival of preterm infants with extremely low birth weight (ELBW), it is also associated with unsatisfactory clinical outcomes when used for prolonged periods. This study aimed to identify factors that may be decisive for extubation success in very low birth weight (VLBW) and extremely low birth weight (ELBW) preterm infants. Methods: The cohort study included preterm infants with gestational age (GA) <36 weeks, birth weight (BW) <1500 grams who underwent IMV, born between 2015 and 2018. The infants were allocated into two groups: extubation success (SG) or failure (FG). A stepwise logistic regression model was created to determine variables associated with successful extubation. Results: Eighty-three preterm infants were included. GA and post-extubation arterial partial pressure of carbon dioxide (PaCO2) were predictive of extubation success. Infants from FG had lower GA and BW, while those from SG had higher weight at extubation and lower post-extubation PaCO2. Discussion: Although we found post-extubation PaCO2 as an extubation success predictor, which is a variable representative of the moment after the primary outcome, this does not diminish its clinical relevance since extubation does not implicate in ET removal only; it also involves all the aspects that take place within a specified period (72 hours) after the planned event. Conclusion: GA and post-extubation PaCO2 were predictors for extubation success in VLBW and ELBW preterm infants. Infants who experienced extubation failure had lower birth weight and higher FiO2 prior to extubation.
ABSTRACT
Objectives: To verify the prevalence of frailty in patients hospitalized with acute exacerbation of COPD; to compare two frailty assessment methods: Edmonton Scale and the Fried Frailty Phenotype, and to associate frailty with functioning in these patients. Methods: Patients hospitalized due to an acute exacerbation of COPD were included. The assessment of pulmonary function, frailty, and functioning was performed. Frailty assessment was performed by the Edmonton Scale and Fried Frailty Phenotype. Individuals were classified into "frail," "pre-frail" and "non-frail." Functioning was evaluated by the one sit-to-stand test. Results: Thirty-five individuals were included (17 male, 69 ± 9 years; FEV1/FVC 47 ± 10%; FEV1 34 (24-52) % predicted). Participants scored 3 (3-4) points on the Edmonton Scale and 7 (5-9) points on the Fried Frailty Phenotype. According to the Fried model, 17% were considered prefrail and 83% frail and in the Edmonton scale, 20% were classified as nonfrail, 29% prefrail, and 51% frail. There was a positive moderate correlation between the two methods (r = 0.42; p=0.011); however, there was no agreement between them (p=0.20). This probably occurs because they assess the same construct, i.e., frailty; however, they are different in their components. There was a negative and moderate correlation between the Fried Frailty Phenotype and functioning (r = -0.43; p=0.009). Conclusion: Most hospitalized individuals with exacerbated COPD with severe and very severe airflow limitation are frail and the assessment methods correlate, but there is no agreement. Additionally, there is association between frailty and functioning in this population.
ABSTRACT
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has affected the mental health, sleep and quality of life, especially in individuals with chronic disease. Therefore, the purpose of this systematic review and meta-analysis was to investigate the impact of the COVID-19 pandemic on neuropsychiatric disorders (depression, anxiety, stress), sleep disorders (sleep quality, insomnia) and quality of life in individuals with Parkinson's disease (PD), Multiple Sclerosis (MS) and Alzheimer's disease (AD) compared to healthy controls. METHODS: Seven databases (Medline, Embase, ScienceDirect, Web of Science, The Cochrane Library, Scielo and Lilacs) were searched between March 2020 and December 2022. Observational studies (i.e., cross-sectional, case-control, cohort) were included. GRADE approach was used to assess the quality of evidence and strength of the recommendation. Effect size was calculated using standardized mean differences (SMD; random effects model). A customized Downs and Black checklist was used to assess the risk of bias. RESULTS: Eighteen studies (PD = 7, MS = 11) were included. A total of 627 individuals with PD (healthy controls = 857) and 3923 individuals with MS (healthy controls = 2432) were analyzed. Twelve studies (PD = 4, MS = 8) were included in the meta-analysis. Individuals with PD had significantly elevated levels of depression (very low evidence, SMD = 0.40, p = 0.04) and stress (very low evidence, SMD = 0.60, p < 0.0001). There was no difference in anxiety (p = 0.08). Individuals with MS had significantly higher levels of depression (very low evidence, SMD = 0.73, p = 0.007) and stress (low evidence, SMD = 0.69, p = 0.03) and low quality of life (very low evidence, SMD = 0.77, p = 0.006). There was no difference in anxiety (p = 0.05) and sleep quality (p = 0.13). It was not possible to synthesize evidence in individuals with AD and sleep disorder (insomnia). CONCLUSION: In general, the COVID-19 pandemic negatively impacted individuals with PD and MS. Individuals with PD showed significantly higher levels of depression and stress; and individuals with MS presented significantly higher depression and stress levels, as well as significantly lower quality of life when compared to healthy controls. Further studies are needed to investigate the impact of the COVID-19 pandemic in individuals with AD.

BACKGROUND: The relationship between pulmonary impairment and frailty has rarely been studied in community-dwelling older adults. OBJECTIVE: This study aimed to analyze the association between pulmonary function and frailty (prevalent and incident), identifying the best cut-off points to detect frailty and its association with hospitalization and mortality. METHODS: A longitudinal observational cohort study with 1188 community-dwelling older adults was taken from the Toledo Study for Healthy Aging. The forced expiratory volume in the first second (FEV1) and the forced vital capacity (FVC) were measured with spirometry. Frailty was evaluated using the Frailty Phenotype and Frailty Trait Scale 5. Associations between pulmonary function and frailty, hospitalization and mortality in a 5-year follow-up and the best cut-off points for FEV1 and FVC were analyzed. RESULTS: FEV1 and FVC were associated with frailty prevalence (OR from 0.25 to 0.60), incidence (OR from 0.26 to 0.53), and hospitalization and mortality (HR from 0.35 to 0.85). The cut-off points of pulmonary function identified in this study: FEV1 (≤1.805 L for male and ≤1.165 L for female) and FVC (≤2.385 L for male and ≤1.585 L for female) were associated with incident frailty (OR: 1.71-4.06), hospitalization (HR: 1.03-1.57) and mortality (HR: 2.64-5.17) in individuals with and without respiratory diseases (P < 0.05 for all). CONCLUSION: Pulmonary function was inversely associated with the risk of frailty, hospitalization and mortality in community-dwelling older adults. The cut-off points for FEV1 and FVC to detect frailty were highly associated with hospitalization and mortality in the 5-year follow-up, regardless of the existence of pulmonary diseases.

BACKGROUND: Regular functional status and muscle strength assessments should be performed with burn victims. OBJECTIVE: To evaluate the functionality and peripheral muscle strength of burn patients admitted to the hospital. METHODS: A longitudinal and prospective study was conducted from March to November 2019, including adult burn victims who were admitted to the ICU and discharged from the hospital. Patients were assessed on admission, every 10 days, at discharge from the ICU and from the hospital. Functionality was assessed using the Chelsea Critical Care Physical Assessment (CPAx) and the Functional Independence Measure (FIM). Muscle strength was assessed using the Medical Research Council (MRC) scale and handgrip dynamometry. RESULTS: 41 patients were included, 27 men and 14 women, with a median age of 41 (IQR [28-56]) years, mean TBSA of 19 (SD ± 12) percent, mean Abbreviated Burn Severity Index (ABSI) of 6 (SD ± 2) and the mean ICU time was 29 (SD ± 9) days. The CPAx, FIM and MRC evaluations improved (P < 0.0001) when compared to admission to the ICU and at hospital discharge, while the dynamometry showed no statistical difference. The ABSI only showed an association with the length of stay. CONCLUSION: The CPAX scale was sensitive to changes in functionality throughout the hospital stay in severely burned patients, in the present study. The assessment of global muscle strength was more sensitive than handgrip strength and the ABSI was associated with length of stay in this population.

Abstract Background: Fatigue is a disabling symptom in the spectrum of Parkinson's disease (PD), affecting from 30% to 70% of the persons. Even though it is a common symptom, with negative repercussions for PD individuals, its correlation with balance is not established. Aim: The aims of this study were to verify the correlation between fatigue and balance in individuals with PD and to compare balance in individuals with PD that presents low fatigue or high fatigue. Methods: This study included 37 individuals with PD, who were divided into two groups: low fatigue (n = 25) and high fatigue (n = 12). Fatigue was evaluated using the Parkinson's disease Fatigue Scale and a force platform was used to assess four balance tasks: bipedal, tandem with eyes open/closed, and tandem with the dual-task, in three parameters: (1) 95% confidence ellipse area of the center of pressure (COP) (2) mean velocity (3) root mean square of COP. To verify the correlation between fatigue and balance, the Spearman rank-order correlation coefficient was assessed. Comparison of medians between the groups was analyzed using the Mann-Whitney test. Results: There was no significant correlation between fatigue and balance. There was no difference between the groups with low and high fatigue. Conclusion: This study's findings, together with those reported in the literature, suggest there is no correlation between fatigue and balance, and even though individuals with PD report fatigue or experience situations of fatigue, they do not present greater posture instability than individuals with PD who do not report fatigue. Fatigue is a disabling symptom in the spectrum of Parkinson's disease (PD), affecting from

OBJECTIVE: To provide reference values for functional fitness tests (PFFT) and verify the capability of these tests alone and grouped into a general index (GFFI-6), to predict mortality from all causes, during seven years of follow-up of physically independent older adults. METHODS: The sample consisted of 422 older adults, evaluated at baseline using six PFFTs, as well as sociodemographic, behavioral, anthropometric, and comorbidity variables. Mortality from all causes was followed for seven subsequent years. The sample was subdivided into four groups according to sex and age. Performances in the PFFT and GFFI-6 tests were ranked into "low", "regular", and "high". RESULTS: Cox proportional regression, with the adjustment of variables, indicated that the Unipedal Balance Test (BAL), Body Agility (AGI), Sit and Stand-up (SIT-SD) tests, and GFFI-6 were able to significantly predict mortality, indicating that older adults with "low" performance have, respectively, a 2.7 (CI=1.54-4.89, p = 0.01), 4.2 (CI=2.10-8.41), 2.5 (CI=1.44-4.65, p = 0.01), and 4.7 (CI=2.10-10.81, p<0.01) times higher risk of death, compared to older adults with "high" performance. CONCLUSION: BAL, AGI, and SIT-SD tests alone and tests grouped in the GFFI-6 were strong predictors of all-cause mortality in physically independent older adults.

ABSTRACT Although patients with chronic obstructive pulmonary disease (COPD) benefit in many ways after participating in pulmonary rehabilitation programs, high dropout rates are still observed among participants. This study aims to analyze the adherence rate and perceived satisfaction in individuals with chronic obstructive pulmonary disease who underwent high-intensity physical training on land (LG) and in water (WG). This study is an additional analysis from a randomized controlled trial. In total, 36 subjects (51%) completed the intervention. All participants underwent six months of high-intensity endurance and strength training. Adherence was assessed by the proportion of patients who completed the training program. Perceived satisfaction was evaluated using a questionnaire composed of structured and semi-structured questions. The interviews were recorded, transcribed, and analyzed according to the criteria of our thematic analysis. The Shapiro-Wilk test was used to assess data normality, and dropout rates were compared using the chi-square test. Statistical significance was set at 5%. Regarding adherence, 59% of WG participants and 44% of LG participants completed the program, with no difference between the groups (p>0.05). Individuals from both groups were equally satisfied after six months of physical training (<90%); the therapist-patient relationship and treatment effectiveness being important factors for this perception. Qualitative analysis also showed that WG participants reported a more prominent improvement in their respiratory symptoms, leisure, sensation of pain, and sleep. In conclusion, patients with COPD were satisfied after six months of high-intensity physical training in water and on land, noting that water exercising promoted additional benefits compared to land exercising. There seems to be no superiority to any of the regimens (water or land) regarding the adherence to the training programs.
RESUMO Embora os pacientes com doença pulmonar obstrutiva crônica (DPOC) se beneficiem de muitas maneiras de programas de reabilitação pulmonar, ainda são observadas altas taxas de desistência entre os participantes. O objetivo deste estudo foi analisar a taxa de adesão e a percepção de satisfação de indivíduos com DPOC que realizaram treinamento físico de alta intensidade em solo (GS) e água (GA). Foram realizadas análises adicionais de um ensaio clínico randomizado. 36 indivíduos (51%) completaram a intervenção. Todos os participantes foram submetidos a seis meses de treinamento de força e resistência de alta intensidade. A adesão foi avaliada pela proporção de pacientes que completaram o programa de treinamento e a satisfação foi avaliada por meio de um questionário composto por questões estruturadas e semiestruturadas. As entrevistas foram gravadas, transcritas e analisadas de acordo com o critério de análise de conteúdo. Foi utilizado o teste de Shapiro-Wilk para avaliar a normalidade dos dados e o teste qui-quadrado para a comparação da taxa de aderência. Foi adotado p<0,05 como significância estatística. Em relação à adesão, 59% dos participantes do GA e 44% do GS completaram o programa, sem diferença entre os grupos (p>0,05). Os indivíduos de ambos os grupos estavam igualmente satisfeitos após seis meses de treinamento físico (<90%), sendo a relação terapeuta-paciente e a eficácia no tratamento fatores importantes para essa percepção. A análise qualitativa também mostrou que os participantes do GA relataram benefícios mais proeminentes em relação aos sintomas respiratórios, ao lazer, a sensação de dor e ao sono. Portanto, os pacientes com DPOC se mostraram satisfeitos após seis meses de treinamento e perceberam que o exercício na água promoveu mais benefícios do que em solo. Em relação à adesão aos programas de treinamento não pareceu haver superioridade de nenhum dos regimes (água ou solo).
RESUMEN Aunque los programas de rehabilitación pulmonar ayudan a los pacientes con enfermedad pulmonar obstructiva crónica (EPOC), todavía se observan altas tasas de abandono de los participantes en estos programas. El objetivo de este estudio fue evaluar la tasa de adherencia y la percepción de satisfacción de las personas con EPOC que realizaron entrenamiento físico de alta intensidad en suelo (GS) y en agua (GA). Se realizaron análisis adicionales de un ensayo clínico aleatorizado. 36 participantes (51%) completaron la intervención. Todos se sometieron a seis meses de entrenamiento de fuerza y resistencia de alta intensidad. La adherencia se evaluó por la proporción de pacientes que completaron el programa de entrenamiento, y la satisfacción se evaluó mediante un cuestionario con preguntas estructuradas y semiestructuradas. Las entrevistas fueron grabadas, después transcritas y analizadas según el criterio de análisis de contenido. Para evaluar la normalidad de los datos, se utilizó el test de Shapiro-Wilk, y para comparar la tasa de adherencia se aplicó la prueba de chi-cuadrado. El nivel de significación estadística fue de p<0,05. En cuanto a la adherencia, el 59% de los participantes del GA y el 44% del GS completaron el programa, sin diferencia entre grupos (p>0,05). Ambos grupos estaban igualmente satisfechos después de seis meses de entrenamiento físico (<90%), por lo que la relación terapeuta-paciente y la eficacia del tratamiento fueron los factores importantes de esta percepción. El análisis cualitativo también apuntó que los participantes de GA informaron más beneficios con respecto a los síntomas respiratorios, el ocio, la sensación de dolor y el sueño. Por lo tanto, los pacientes con EPOC estaban satisfechos después de seis meses de entrenamiento y se dieron cuenta de que el ejercicio en el agua les brindaba más beneficios que el ejercicio en el suelo. En cuanto a la adherencia al carácter de los programas de entrenamiento (si agua o suelo), no pareció haber superioridad en ninguno de ellos.
ABSTRACT
BACKGROUND: The relation between oxidative stress (OS) and sarcopenia in COPD remains unknown. OBJECTIVE: To analyze OS levels and its association with sarcopenia in COPD. METHODS: Thirty-nine individuals with COPD (69±7years; 41%female) and thirty-five for the control group (69±7years; 43%female) were included. Advanced oxidation protein products (AOPP), paraoxonase-1 (PON1), superoxide dismutase activity (SOD), catalase dismutase activity (CAT), sulfhydryl group (SH), nitric oxide metabolites (NOX), total radical trapping antioxidant parameter (TRAP) were analysed. OS markers were correlated with handgrip and quadriceps strength, gait speed, skeletal muscle mass index, fat-free mass index, maximum inspiratory and expiratory pressure. European criteria were used to identify sarcopenia. RESULTS: In COPD, antioxidant capacity was correlated with muscle mass and strength (r from 0.5 to 0.64) P<0.05 for all. TRAP≤ 850 µM/trolox and AOPP≤65 µM/l were associated with sarcopenia (OR:8.3; 95% CI: 1.4-49.6 and OR:14; 95%CI: 2.2-87.1, respectively; P<0.05 for both). CONCLUSION: OS is associated with sarcopenia in COPD.

INTRODUCTION: The perception of health professionals about chronic obstructive pulmonary disease (COPD) has not been thoroughly investigated. OBJECTIVE: To analyze the perception of health professionals about the impact of COPD on the lives of affected individuals. MATERIALS AND METHODS: Qualitative and cross-sectional study with five health professionals: two nurses, two physiotherapists, and one medical doctor. They participated in a focus group (FG) session, with semistructured questions covering: definition of COPD, activities of daily living (ADL), and physical activity of daily living (PADL), as well as the importance of these outcomes in the lives of individuals with COPD. DATA ANALYSIS: The FG was recorded, transcribed, and analyzed according to the content analysis. RESULTS: The FG highlighted four main themes: physical-functional and emotional impairment of individuals, the importance of patient-health professional contact, repercussions of COPD on the patients' physical activity, and strategies for promoting physical activity. Based on the four themes exposed, the health professionals reported that there is a progression in the lives of individuals' with COPD, which is divided into three phases: adaptation, reluctance, and dependence. CONCLUSION: There was a negative perception of the health professionals regarding the functionality and emotion of patients with COPD. Emotional aspects, family support, and architectural structure can positively or negatively influence patients' ADL and PADL. Finally, there was a perception of progression in the life of patients with COPD, since their initial adaptation, evolving to physical and emotional dependence.

BACKGROUND: The mechanisms underlying impaired balance in chronic obstructive pulmonary disease (COPD) are poorly understood, which makes it difficult to choose the best therapeutic approaches. Therefore, this study aimed to investigate patterns of muscular activation to maintain balance and its determinants in this population. METHODS: Thirty-three subjects with COPD and 33 controls were assessed by a force platform in four tasks: standing with eyes opened (FHEO) and closed (FHEC); standing on unstable surface (SUS) and one-legged stance (OLS). Electromyographic activity of lower limb, trunk and neck muscles was concomitantly recorded. To asses functional balance, Brief-balance evaluation systems and timed up & go (TUG) tests were applied. Lung function, exercise capacity and muscle force were also assessed. RESULTS: Subjects with COPD presented worse balance and higher scalene activation than controls in OLS (mean difference 23.0 [95%CI 1.7-44.3] %Δ µVRMS; P = 0.034), besides presenting also higher activation of gluteus medius during FHEC task (mean difference 1.5 [95%CI 0.2-2.8] %Δ µVRMS; P = 0.023) and taking longer to complete the TUG (mean difference 0.6 [95%CI 0.1-1.2] seconds; P = 0.042). Exercise capacity and peripheral muscle force were determinants of functional balance (r2 = 0.505), whereas age (OR = 1.24; 95%CI 1.02-1.52) and total lung capacity (OR = 2.42; 95%CI 1.05-5.56) were determinants of static balance. CONCLUSION: Individuals with COPD have worse static and functional balance in comparison with controls, besides presenting higher activation of scalene and gluteus medius during static balance tasks. Exercise capacity and peripheral muscle force emerged as determinants of functional balance, whereas age and lung hyperinflation contributed to poor static balance.

PURPOSE: This study aimed to investigate whether patients with chronic obstructive pulmonary disease (COPD) presenting asthma overlap (ACO) benefit similarly in comparison to patients with only COPD after a 12-week high-intensity exercise training (ET) program. METHODS: Subjects with a diagnosis of COPD alone or ACO were evaluated and compared before and after a high-intensity ET program composed of walking and cycling plus strengthening exercises of the upper and lower limbs (3 days/week, 3 months, 36 sessions). Assessments included spirometry, bioelectrical impedance, 6-min walk test (6MWT), London Chest Activity of Daily Living Scale (LCADL), Hospital anxiety and depression Scale, modified Medical Research Council Scale (mMRC), Saint George Respiratory Questionnaire (SGRQ), and respiratory and peripheral muscle strength [manovacuometry and 1-repetition maximum test (quadriceps femoris, biceps and triceps brachialis), respectively]. ACO was defined according to Sin et al. (Eur Respir J 48(3):664-673, 2016). RESULTS: The sample was composed of 74 subjects (57% male, age 67 ± 8 years, BMI 26 (21-32) kg/m2, FEV1 47 ± 17%predicted), and 12 (16%) of them were classified as presenting ACO. Both groups improved pulmonary function, 6MWT, peripheral and inspiratory muscle strength, LCADL, and SGRQ after ET (p < 0.005 for all). There were no significant interactions between ACO and COPD on ET effects (p > 0.05 for all). Likewise, there was no difference in the proportion of patients achieving the minimum clinical important difference for 6MWT and mMRC. CONCLUSION: High-intensity exercise training generates similar benefits in patients with COPD regardless of whether presenting asthma overlap or not.

La sarcopenia es una enfermedad caracterizada por la pérdida de masa muscular, fuerza muscular y rendimiento físico, siendo la principal causa de fragilidad en los adultos mayores. La sarcopenia es altamente prevalente en individuos con enfermedad pulmonar obstructiva crónica (EPOC) que conduce a un mal pronóstico y una mayor mortalidad en esta población. La presencia de sarcopenia en la EPOC es probablemente el resultado de la interacción entre factores externos e internos como la inflamación sistémica, el estrés oxidativo y los polimorfismos genéticos, frecuentemente observados en individuos con esta enfermedad respiratoria. Esta revisión resume el conocimiento sobre los mecanismos patogénicos asociados con la sarcopenia en la EPOC.
Sarcopenia is a disease characterized by loss of skeletal muscle, muscle strength and physical performance, being the major cause of frailty in the elderly. The sarcopenia is highly prevalent in individuals with Chronic obstructive pulmonary disease (COPD) leading to a poor prognosis and higher mortality in this population. The presence of sarcopenia in COPD is likely the result by the interaction between external and internal factors as systemic inflammation, oxidative stress and genetic polymorphisms, frequently observed in individuals with this respiratory disease. This review summarizes the current knowledge about the pathogenic mechanisms linking COPD with sarcopenia.

PURPOSE: Whether the difference in the impact of chronic obstructive pulmonary disease (COPD) on the functional status of men and women stems from clinical distinctions or to the measuring instrument used is unclear. Like most instruments for assessing functional limitation in COPD, the interpretation of the results of the London Chest Activity of Daily Living (LCADL) scale is limited because a lack of a valid cutoff point to this scale. For that, this study sought to compare the functional status between men and women with COPD; and propose a cutoff point for LCADL capable of discriminating the prognosis of these individuals. METHODS: A sample of 138 subjects with moderate-severe COPD was evaluated by the LCADL. The percentage of the individual maximum score was used to obtain a cutoff point capable of discriminating patients with the worse prognosis according to the BODE Index. The cutoff point was also tested in an independent sample (n = 70). RESULTS: Regarding the total score, domestic and leisure domains of the LCADL, men had better scores than women (P ≤ 0.01). The cutoff point found was 37% (area under the curve = 0.70, 95% confidence interval = 0.60-0.80, sensitivity = 0.55 and specificity = 0.74). Individuals who scored ≥ 37% had a worse prognosis and level of physical activities of daily living than those who scored below (P ≤ 0.02). CONCLUSION: When evaluated by the LCADL, men and women with COPD present difference in the functional status. The established cutoff point (37%) adequately discriminates individuals regarding the prognosis, contributing to improve the interpretation capacity of the LCADL.

The objective of the article is to identify clusters of patients with COPD according to factors known to be associated with mortality and to verify whether clusters' assignment is associated with 2-year mortality. Patients ( n = 141) were evaluated by bioelectrical impedance, maximal inspiratory pressure (MIP), one-repetition maximum test of the quadriceps femoris (1RMQF) and BODE index (body mass index; airflow obstruction (spirometry); dyspnea (modified Medical Research Council scale); and exercise capacity (6-minute walk test (6MWT) distance). Vital status was retrospectively checked 2 years after the assessments, and time to death was quantified for those deceased in this period. K-means analysis identified two clusters. Patients in cluster one (CL I, n = 69) presented an impaired clinical status in comparison to cluster two (CL II, n = 72). Receiver operating characteristics curves identified the cutoffs discriminating patients composing CL I: forced expiratory volume in the first second <44%pred; 6MWT <479 m; 1RMQF <19 kg; and maximum inspiratory pressures <73 cmH2O (area under the curve range 0.750-0.857). During the follow-up, 19 (13%) patients deceased, 15 in CL I (22%) and 4 in CL II (0.06%) ( p = 0.005). CL I was associated with a higher risk of 2-year mortality (hazard ratio (95% confidence interval): 4.3 (1.40-12.9), p = 0.01). A cluster of patients with COPD highly associated with 2-year mortality was statistically identified, and cutoffs to identify these subjects were provided.

AIM: To investigate whether being part of a community organization interfered with older adults' overall functionality. The magnitude of responses to a community exercise program based on functional circuits in socially active and socially non-active older adults was also investigated. METHODS: A total of 200 older adults aged ≥60 years from Requinoa, Chile, participated in the study. Participants were separated into two groups according to the level of social participation: socially active (SA) and socially non-active (SNA). During an evaluation, data regarding the presence of comorbidities (Charlson Comorbidity Index), disability level (Modified Health Assessment Questionnaire), dynamic balance (Timed Up and Go test), muscle force (handgrip dynamometry) and sociodemographic conditions were collected. Participants followed an exercise program consisting of a functional exercise circuit including balance, resistance and aerobic exercises, twice a week, for 12 weeks. RESULTS: Both the Charlson Comorbidity Index and disability were higher in SNA compared with SA participants on inclusion. Both groups improved disability (Δ-0.25 patients [-0.5 - -0.0625 patients] for SNA and (Δ-0.125 patients [-0.5-0 patients] for SA) and balance (Δ-2 s [-3-0 s] for SNA and (Δ-1 s [-3-0 s] for SA) after training (P < 0.05 for all). Changes from baseline were statistically higher in the SNA group. Handgrip force improved only in participants in the SNA group (Δ1.7 kg [0.6-2.8 kg], P = 0.0001). No differences, however, were observed between the magnitude of improvements of handgrip between groups. CONCLUSIONS: Although socially non-active older adults had more comorbidity and disability than their socially active counterparts, they showed a higher response to a community exercise program.
