Cardiovascular, Respiratory, and Functional Effects of Home-Based Exercise Training after COVID-19 Hospitalization.

INTRODUCTION: The present randomized, single-center, and single-blinded clinical trial tested the hypothesis that tele-supervised home-based exercise training (exercise) is an effective strategy for improving cardiovascular, respiratory, and functional capacity parameters in individuals who were hospitalized due to coronavirus disease 2019 (COVID-19). METHODS: Thirty-two individuals (52 ± 10 yr; 17 were female) randomly assigned to exercise ( n = 12) or control groups ( n = 20) had their anthropometric (weight, body mass index), hemodynamic (brachial and central blood pressure), vascular (arterial stiffness), ventilatory (pulmonary function and respiratory muscle strength), and functional parameters (handgrip strength, five-time sit to stand, timed up and go test, and 6-min walking test) assessed at baseline (30-45 d of hospital discharged) and after 12 wk of follow-up. RESULTS: Both groups similarly increased ( P < 0.001) forced vital capacity (absolute and percent of predicted), forced expiratory volume in the first second (absolute and percent of predicted), and handgrip strength during follow-up. However, only the exercise group reduced carotid-femoral pulse wave velocity (-2.0 ± 0.6 m·s -1 , P = 0.048) and increased ( P < 0.05) resting oxygen saturation (1.9% ± 0.6%), mean inspiratory pressure (24.7 ± 7.1 cm H 2 O), mean expiratory pressure (20.3 ± 5.8 cm H 2 O), and percent of predicted mean expiratory pressure (14% ± 22%) during follow-up. No significant changes were found in any other variable during follow-up. CONCLUSIONS: Present findings suggest that tele-supervised home-based exercise training can be a potential adjunct therapeutic to rehabilitate individuals who were hospitalized due to COVID-19.

Can Previous Levels of Physical Activity Affect Risk Factors for Cardiorespiratory Diseases and Functional Capacity after COVID-19 Hospitalization? A Prospective Cohort Study.

Purpose: To evaluate the influence of previous levels of physical activity on hemodynamic, vascular, ventilatory, and functional outcomes after coronavirus disease 2019 (COVID-19) hospitalization. Methods: Sixty-three individuals with COVID-19 had their clinical status and previous levels (12 month) of physical activity (Baecke Questionnaire of Habitual Physical Activity) assessed at hospital admission. Individuals were then allocated to lower levels of physical activity (ACTLOWER; N = 22), intermediate levels of physical activity (ACTINTERMEDIATE; N = 22), or higher levels of physical activity (ACTHIGHER; N = 19) groups, according to tertiles of physical activity. Resting hemodynamic (heart rate and brachial/central blood pressures) and vascular (carotid-femoral pulse wave velocity, augmentation index, and brachial artery flow-mediated dilation) variables, pulmonary function (spirometry), respiratory muscle strength (maximal respiratory pressures), and functional capacity (handgrip strength, five-time sit-to-stand, timed-up and go, and six-minute walking tests) were measured at 30 to 45 days after hospital discharge. Results: ACTLOWER showed lower levels (P < 0.05) of forced vital capacity, forced expiratory volume in the first second, maximal voluntary ventilation, and maximal expiratory pressure than ACTHIGHER. ACTLOWER also had lower (P = 0.023) walking distance (~21%,) and lower percentage of predicted walking distance (~20%) at six-minute walking test during follow-up than ACTINTERMEDIATE. However, hemodynamic and vascular variables, handgrip strength, five-time sit-to-stand, and timed-up and go were not different among groups. Conclusion: ACTLOWER showed impaired ventilatory parameters and walking performance when compared with ACTHIGHER and ACTINTERMEDIATE, respectively. These results suggest that previous levels of physical activity may impact ventilatory and exercise capacity outcomes 30 to 45 days after COVID-19 hospitalization discharge.

Determinants of endothelial dysfunction in noncritically ill hospitalized COVID-19 patients: A cross-sectional study.

OBJECTIVE: The aim of this study was to identify determinants of endothelial dysfunction in patients hospitalized with acute COVID-19. METHODS: A total of 109 hospitalized COVID-19 patients in noncritical status were cross-sectionally studied. Clinical data (age, sex, comorbidities, and medications) and BMI were assessed. Laboratory tests included serum hemoglobin, leukocytes, lymphocytes, platelets, C-reactive protein, ferritin, D-dimer, and creatinine. Physical status was evaluated using a handgrip dynamometer. Endothelial function was assessed noninvasively using the flow-mediated dilation (FMD) method. RESULTS: The sample average age was 51 years, 51% of patients were male, and the most frequent comorbidity was obesity (62%). Univariate analysis showed association of lower FMD with higher BMI, hypertension, use of oral antihypertensive, higher blood levels of creatinine, and larger baseline artery diameter. After adjusting for confounders, the multivariate analysis showed BMI (95% CI: -0.26 to -0.11; p < 0.001) as the major factor associated with FMD. Other factors associated with FMD were baseline artery diameter (95% CI: -1.77 to -0.29; p = 0.007) and blood levels of creatinine (95% CI: -1.99 to -0.16; p = 0.022). CONCLUSIONS: Increased BMI was the major factor associated with endothelial dysfunction in noncritically hospitalized COVID-19 patients. This may explain one of the pathways in which obesity may increase the risk for severe COVID-19.

Musculoskeletal, cardiorespiratory, anthropometric and sensorial changes following breast cancer surgery / Alterações musculoesquelética, cardiorrespiratória, antropométrica e sensorial após cirurgia de câncer de mama

Abstract Introduction: Breast cancer is the second most common malignant neoplasm in women. Surgical intervention is one of the recommended treatments, which can lead to significant physical and sensorial sequelae. Objective: To analyze the musculoskeletal, cardiorespiratory, anthropometric and sensorial functions of women who underwent breast cancer surgery. Methods: An observational, cross-sectional study with women who underwent surgical resection of breast tumors at Amaral Carvalho, a reference hospital in the countryside of the São Paulo State, Jaú/SP, Brazil. Three assessments were obtained: pre-surgery (Ass1), one day after the surgery (Ass2) and 15 days after surgery (Ass3). Sociodemographic and gynecological data were collected, and anthropometric, cardiovascular, dermal sensitivity, range of motion (ROM) of the upper limbs, peripheral oxygen saturation (SpO2), inspiratory muscle strength (PImax), peak expiratory flow (PEF) and thoraco-abdominal mobility assessments were performed. Data were evaluated by repeated measures ANOVA and Wilcoxon statistical test with a Bonferroni correction (p < 0.05). Results: Eighteen women, with a mean age of 57.44 ± 9.35 years, mainly with the left side affected (61.1%) and lymphadenectomy performed in 50% of the cases. Differences were found in systolic and diastolic blood pressure, PEF and SpO2, axillary ROM index (Ass1>Ass2), PImax (Ass3>Ass2), perimetry (Ass2>Ass3), ROM in all axes of shoulder motion and wrist flexion (Ass2<Ass1), and sensitivity alteration close to the surgical wound (Ass3>Ass2 and Ass1). Conclusion: The surgery for breast cancer excision resulted in hemodynamic and respiratory changes, especially on the first day after the procedure, returning to baseline values approximately 15 days later.

High-resolution magic angle spinning nuclear magnetic resonance (HR-MAS NMR) as a tool in the determination of biomarkers of Passiflora-based herbal medicines.

High-resolution magic-angle spinning nuclear magnetic resonance spectroscopy (HR-MAS NMR) for the identification of the metabolic profile of plants under conditions very close to that in which the compounds are present in the matrix, the herbal medicines in this case. This enables selectivity in the determination of the active principle and other biomarkers present in the complex matrix, avoiding degradation products, which may occur in the extractive processes required in several analytical methods. In this study, HR-MAS analysis was applied in the quality control of seven Passiflora-based herbal medicines, using metabolic fingerprinting to confirm plant species and identify biomarkers. Vitexin and isovitexin were identified as major compounds in three of these herbal medicines (0.17 to 0.55%), while salicin was the majority in two others. On the other hand, no significant flavonoid contents were observed in the remaining two. In addition, it was possible to detect ethanol, a non-target compound, in all herbal medicines in concentrations varying between 0.009 and 0.342%. In this way, combined with chemometrics 1H HR-MAS NMR proved to be suitable for the qualitative and quantitative study of Passiflora biomarkers, using a minimal pre-treatment of the sample.

Falha de extubação em unidade de terapia intensiva pediátrica: estudo de coorte retrospectivo / Fracaso de la extubación en una unidad de cuidados intensivos pediátrica: un estudio de cohorte retrospectivo / Extubation failure in pediatric intensive care unit: a retrospective cohort study

RESUMO Na unidade de terapia intensiva (UTI) pediátrica, a falha de extubação pode aumentar o risco de mortalidade. Este estudo objetivou: (1) verificar a taxa de falha de extubação na UTI pediátrica de um hospital público do município de Bauru (São Paulo, Brasil); (2) identificar a principal causa atribuída à falha de extubação; (3) avaliar se características como a idade e o tempo de ventilação mecânica invasiva (VMI) estão associadas à falha de extubação; (4) avaliar se o tempo de permanência na UTI e hospital é maior entre os pacientes que apresentaram falha de extubação. Foi realizado estudo de coorte retrospectivo com 89 pacientes internados de maio de 2017 até julho de 2018. Os resultados mostraram taxa de falha de extubação correspondente a 16%. A principal causa atribuída à falha de extubação foi o estridor laríngeo, totalizando 57% dos casos. A comparação intergrupos (sucesso vs. falha de extubação) não mostrou diferenças em relação à idade (p=0,294) e ao tempo de VMI (p=0,228). No entanto, observamos que o grupo falha de extubação apresentou maior tempo de UTI (p=0,000) e hospital (p=0,010). Desta forma, concluímos que a taxa de extubação está de acordo com a observada em outros estudos. O estridor laríngeo foi responsável por mais da metade dos casos de falha de extubação. Embora a idade e o tempo de VMI não tenham sido características associadas à falha de extubação, esta contribuiu para o maior período de permanência na UTI e no hospital.

RESUMEN En la unidad de cuidados intensivos (UCI) pediátrica, el fracaso de la extubación puede aumentar el riesgo de mortalidad. Este estudio tuvo el objetivo de: (1) verificar el índice de fracaso de la extubación en la UCI pediátrica de un hospital público en el municipio de Bauru (São Paulo, Brasil); (2) identificar la causa principal atribuida al fracaso de la extubación; (3) evaluar si las características edad y tiempo de ventilación mecánica invasiva (VMI) están asociadas al fracaso de la extubación; (4) evaluar si la duración en la UCI y el hospital es mayor entre los pacientes que experimentaron este fracaso. Se realizó un estudio de cohorte retrospectivo con 89 pacientes hospitalizados desde mayo de 2017 hasta julio de 2018. Los índices del fracaso de la extubación fueron del 16%. El estridor laríngeo fue la causa principal atribuida al fracaso de la extubación, lo que totaliza el 57% de los casos. La comparación intergrupal (éxito versus fracaso de la extubación) no presentó diferencias en relación con la edad (p=0,294) y el tiempo VMI (p=0,228). Se observó que el grupo fracaso de la extubación estuvo más tiempo en la UCI (p=0,000) y el hospital (p=0,010). Se concluye que el índice de extubación está en consonancia con lo observado en otros estudios. El estridor laríngeo fue el responsable de más de la mitad de los casos de fracaso de la extubación. Las características edad y el tiempo de VMI no estuvieron asociadas al fracaso de la extubación, pero esta contribuyó a un período más prolongado en la UCI y en el hospital.

ABSTRACT In the pediatric intensive care unit (ICU), extubation failure may increase mortality risk. This study aimed: (1) to verify the rate of extubation failure in the pediatric ICU of a public hospital located in the city of Bauru (São Paulo, Brazil); (2) to identify the main cause attributed to extubation failure; (3) to evaluate whether age and time of invasive mechanical ventilation (IMV) are characteristics associated to extubation failure; (4) to evaluate whether the length of stay in the ICU/hospital is longer among patients who presented extubation failure. A retrospective study was performed with 89 hospitalized patients from May 2017 to July 2018. Results showed an extubation failure rate corresponding to 16%. The main cause attributed to extubation failure was laryngeal stridor, totaling 57% of the cases. Intergroup comparison (success vs. failure of extubation) showed no differences in relation to age (p=0.294) and IMV time (p=0.228). However, we observed that the extubation failure group had longer ICU (p=0.000) and hospital time (p=0.010). In this way, we conclude that the rate of extubation failure is in agreement with other studies. Laryngeal stridor was responsible for more than half of cases of extubation failure. Although IMV time and age were not associated with the extubation failure, they contributed to a longer stay in the ICU and in the hospital.

Impact of deep water running in interval training (DWR-IT) on body composition, functional capacity, and quality of life in overweight adults: study protocol for a randomized controlled trial.

BACKGROUND: Interval training in deep water running (DWR-IT) is a training method to improve cardiovascular fitness, functional health, and quality of life and to help control body weight. Its main advantages are the reduction of joint overload and a low risk of musculoskeletal injuries. The aim of the study is to investigate the influence of DWR-IT on functional capacity, body composition, and quality of life of overweight middle-aged adults. METHODS: This is a randomized controlled, two-arm, open, parallel clinical trial with overweight adults. Volunteers will be allocated to a water group (WG), which will be submitted to the intervention, or a control group, which will not be subjected to any kind of intervention. The evaluation will be composed of anamnesis, electrical bioimpedance, six-minute walk test (6MWT), questionnaire on the Impact of Weight on Quality of Life-lite (IWQOL-LITE), Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, chair stand test, arm curl test, and food frequency questionnaire. The DWR-IT will last for 12 weeks, systematically increasing the intensity and training volume. DISCUSSION: The objective of this clinical trial is to evaluate the effect of DWR-IT on overweight adults. The study is guided through practice based on scientific evidence for the use of training and aquatic rehabilitation. It is expected that after 12 weeks of aquatic intervention there will be a decrease in body fat by about 10%, evaluated by electrical bioimpedance, an increase of about 25% of cardiorespiratory endurance, evaluated by 6MWT, and an improvement of about 25% of physical function domains, self-esteem, distress in public places, and work, analyzed by IWQOL-LITE in the WG. TRIAL REGISTRATION: The study protocol was published in the Brazilian Registry of Clinical Trials (ReBEC) on June 16, 2016. Registration number: RBR-6dmh7d.

Lipid profile, functional capacity and ankle-brachial index in active older adults / Perfil lipídico, capacidade funcional e índice tornozelo-braquial em idosos ativos / Perfil lipídico, capacidad funcional e índice tobillo-braquial en adultos de la tercera edad activos

ABSTRACT Introduction: Regular physical activity prevents cardiovascular diseases (CVD) and atherosclerosis, in addition to improving lipid levels and functional capacity in older adults. Objective: To evaluate and compare the lipid levels, functional performance and ankle brachial index (ABI) of sedentary and active older adults. Methods: This was a comparative cross-sectional study with 84 elderly (≥60 years) male and female subjects, divided into two groups: sedentary group (SG, n = 50) and active group (AG, n = 34) according to the International Physical Activity Questionnaire (IPAQ). Anthropometric and hemodynamic assessments, ankle brachial index (ABI) calculations, and functionality tests (Short Physical Performance Battery - SPPB and 6-minute walking test - 6MWT) were performed. The Shapiro-Wilk normality test was also used, and we conducted the Student's-t and Mann-Whitney tests for the intergroup comparison. For the categorical data, we used Fisher's exact test (p <0.05). Results: Higher values of high-density lipoprotein cholesterol (HDL-c) (p = 0.001) and lower triglycerides (TG) (p = 0.007) were found in AG compared to SG. In the ABI evaluation, AG presented better right (p = 0.012), left (p = 0.015) and end (p = 0.004) ABI rates when compared to SG. AG had better results in functional performance in the SPPB evaluation (p = 0.0007) and in the 6MWT with a greater distance covered (p = 0.0027). In the anthropometric measurements, AG had lower body mass index (BMI) (0.041) and a smaller abdominal circumference (WC) (0.029). In terms of the incidence of referred diseases, intergroup results were only different for hypertension (0.029), while AG had a lower incidence of hypertension. Conclusion: Active older adults had better lipid levels, higher ABI levels, better functional performance, lower body mass, a smaller abdominal circumference, and lower incidence of hypertension, in comparison to sedentary subjects. Level of evidence I; High quality prospective study.

Important issues in plant tissues analyses by HR-MAS NMR.

INTRODUCTION: High-resolution magic-angle spinning nuclear magnetic resonance (HR-MAS NMR) spectroscopy enables the analysis of the metabolic profile of plant and animal tissues under close to natural conditions, as well as of other heterogeneous natural or synthetic materials. Neither sample pretreatment is required after fragmentation nor powdering of the sample before insertion into the rotor. However, the efficiency of the method depends strongly on the sample preparation, rotor insertion procedure, and analysis conditions. OBJECTIVE: To identify some of the variables that affect the spectral data and to propose solutions that minimise their impact on the quality of the analyses and results. METHODS: Dried plant tissues were powdered, weighed, and homogenised in a 50 µL rotor with an optimised volume of deuterated solvent and sample in order to prevent material from escaping during spacer insertion, avoiding variations in magnetic susceptibility. Factors affecting the quality of HR-MAS NMR analysis such as particle size, sample and solvent amounts, solvent polarity, swelling time, rotor manipulation and pulse sequence setting were evaluated. RESULTS: A strong correlation was observed between the signal area and the particle size of the powdered sample. The spectral profile varied depending on the deuterated solvent used. An incubation period was necessary to achieve adequate swelling of the sample and to ensure good data reproducibility. Proper sealing of the rotor, number of cycles and τ time on cpmgpr1d pulse sequence were found to affect the signal areas. CONCLUSION: The study highlights the need for standardised sample preparation and instrumental setup protocols in order to achieve high reproducibility and obtain reliable data from HR-MAS NMR analyses.

Obesidade abdominal e o sistema respiratório / Abdominal obesity and respiratory system

Introdução: A área da pneumologia tem dado importância para a associação da função respiratória com a obesidade. As transformações orgânicas decorrentes da obesidade implicam em alterações dos sistemas respiratório, imunomodulador, metabólico (musculatura esquelética, consumo de oxigênio e produção de gás carbônico) e circulatório. Este trabalho tem por objetivo revisar sobre o tema obesidade abdominal e sistema respiratório. Métodos: Revisão de literatura usando as bases de dados Scielo, Bireme, Pubmed e Scopus tendo como descritores: circulatory and respiratory physiological phenomena; respiratory function tests e abdominal obesity, sem limite para o ano de publicação e idioma. Resultados: A obesidade pode afetar o sistema respiratório independente da condição do parênquima pulmonar. Em indivíduos obesos, o mecanismo de respiração está prejudicado, pois o excesso de adiposidade que reveste o tórax e ocupa o abdome dificulta a ação da musculatura respiratória. A obesidade abdominal não é apenas um fator estético ou metabólico, mas também um fator mecânico que pode comprometer a função da musculatura respiratória e consequentemente a função pulmonar. As alterações na função respiratória mais frequentemente encontradas na obesidade são: redução do volume de reserva expiratório, capacidade vital, capacidade residual funcional e capacidade pulmonar total. Além do impacto mecânico, respiratório e cardiovascular, a obesidade também interfere para o estímulo e controle do sistema nervoso autônomo. Conclusão: A obesidade abdominal está interligada a fatores respiratórios desde o controle central respiratório até limitação dos constituintes respiratórios podendo ocasionar distúrbio respiratório restritivo e obstrutivo.

Introduction: The field of pneumology pointed out the association of respiratory function with obesity. The organic changes due to obesity imply changes in the respiratory, immunomodulatory, metabolic (skeletal musculature, oxygen consumption and carbon dioxide production) and circulatory systems. The aim of his study was a review about abdominal obesity and respiratory system. Methods: Literature review using the Scielo, Bireme, Pubmed and Scopus databases, and the following descriptors: circulatory and respiratory physiological phenomena; respiratory function tests and abdominal obesity, no limit to the year of publication and language. Results: Obesity can affect the respiratory system independent of pulmonary parenchyma condition. In obese individuals, the breathing mechanism is impaired, because the excess of fat that lines the chest and occupy the abdomen makes it difficult for the respiratory musculature to function. Abdominal obesity is not only an aesthetic or metabolic factor, but also a mechanical factor that can compromise respiratory muscle function and consequently lung function. The changes in respiratory function most frequently found in obesity are: reduction of expiratory reserve volume, vital capacity, functional residual capacity and total lung capacity. Besides the mechanical, respiratory and cardiovascular impact, obesity also interferes with the stimulation and control of the autonomic nervous system. Conclusion: Abdominal obesity is interrelated to respiratory factors from central respiratory control to limitation of respiratory constituents and can cause restrictive and obstructive respiratory disorder.

Cardiorespiratory repercussions according to the abdominal circumference measurement of men with obstructive respiratory disorder submitted to respiratory physiotherapy.

PURPOSE: To examine the effect of respiratory physiotherapy among men with obstructive respiratory disorder, in relation to abdominal circumference (AC). METHODS: Quasi-experimental study including 26 men split into two groups according to AC(cm): 1) < 102 (ACrisk-free); and 2) ≥ 102 (ACrisk). Heart rate variability (HRV), diastolic blood pressure (DBP), oxygen saturation (SpO2), FEV1/FVC, slow vital capacity (SVC), inspiratory capacity (IC), maximal inspiratory pressure (PImax), thoracoabdominal amplitude (AI) were measured: before (M1); 5 min after the physiotherapy (i.e. breathing exercises for airway clearance and active kinesiotherapy) (M2); and at follow-up, 30 min after physiotherapy (M3). RESULTS: The groups differed in age, body mass index and body fat %. At M2 IC was different between groups (ACrisk-free< ACrisk). There was an increase in HRV indexes, PImax, SpO2, axillary AI, FEV1/FVC, and reduction in HR for ACrisk-free. There was a decrease in AI and an increase in DBP for ACrisk. CONCLUSION: In men with obstructive respiratory disorder, increased AC measurement limited the thoracoabdominal expansibility and induced a rise of the DBP. Respiratory physiotherapy promotes an increase of cardiac modulation and inspiratory capacity for men with obstructive respiratory disorder.

Multicomponent training to improve the functional fitness and glycemic control of seniors with type 2 diabetes / Treinamento multicomponente melhora a aptidão funcional e controle glicêmico de idosos com diabetes tipo 2

ABSTRACT Type 2 diabetes mellitus (T2DM) is a prevalent disease in older adults and associated with functional impairment and abnormalities of the glycemic metabolism. Multicomponent training, which consists of strength, balance, coordination, gait, agility and proprioception exercises, is recommended to improve the physical function of the elderly, but its effects in the treatment of T2DM are not clear. The main goal was to investigate the effect of a multicomponent training protocol on functional and glycemic parameters in seniors with T2DM. Thirteen older adults (68±6 years) with T2DM were included. Before and after the intervention period, the following tests were performed: chair stand, arm curl, sit and reach, six-minute walk test (6MWT), fasting blood glucose and glycated hemoglobin (HbA1C). The training program was conducted for 16 weeks, three times a week, on nonconsecutive days. Each session consisted of 10 minutes of warm-up, 50 minutes of multicomponent exercises (coordination, muscle strength, flexibility, balance and agility) and 10 minutes of stretching and relaxation. Statistical analysis was performed using paired t-test and the Wilcoxon test (p<0.05). Training induced an improvement in the arm curl (p = 0.001), sit and reach (p = 0.004), 6MWT (p = 0.009) and HbA1C (p = 0.01) tests. In conclusion, the multicomponent training protocol improved functional fitness and glycemic control in seniors with T2DM. However, fasting blood glucose levels and muscle strength of the lower limbs remained unchanged

RESUMO A diabetes mellitus tipo 2 (DM2) é uma doença prevalente em idosos e está associada à incapacidade funcional e anormalidades do metabolismo glicêmico. O treinamento multicomponente, composto por exercícios de força, equilíbrio, coordenação, marcha, agilidade e propriocepção, é recomendado para melhorar a função física de idosos, porém seus efeitos no tratamento da DM2 não estão claros. Objetivou-se investigar o efeito de um protocolo de treinamento multicomponente na aptidão funcional e parâmetros glicêmicos de idosos com DM2. Foram incluídos 13 idosos com DM2 e idade de 68 ± 6 anos. Antes e após o período de intervenção foram realizados os seguintes testes: chair stand, arm curl, sentar e alcançar, teste de caminhada de seis minutos (TC6M), glicemia de jejum e hemoglobina glicada (HbA1C). O programa de treinamento foi realizado por 16 semanas, três vezes/semana, em dias não consecutivos. Cada sessão consistiu de 10 minutos de aquecimento, 50 minutos de exercícios multicomponentes (coordenação, força muscular, flexibilidade, equilíbrio e agilidade) e 10 minutos de alongamento e relaxamento. Para a análise estatística foi utilizado o teste t pareado e teste de Wilcoxon (p<0,05). O treinamento induziu melhora nos testes arm curl (p = 0,001), sentar e alcançar (p = 0,004), TC6M (p = 0,009) e HbA1C (p = 0,01). Conclui-se que o protocolo de treinamento multicomponente promoveu melhora da aptidão funcional e do controle glicêmico em idosos com DM2. Entretanto, a glicemia de jejum e a força muscular de membros inferiores permaneceram inalteradas.

Clinical outcomes related to the incidence of ventilator-associated pneumonia in adults - a cohort study / Desfechos clínicos ligados à incidência de pneumonia associada à ventilação mecânica no adulto - estudo de coorte

Abstract Introduction: Ventilator-Associated Pneumonia (VAP) is a common complication found in the Intensive Care Unit (ICU) and is associated with increased mortality, length of hospital stay and mechanical ventilation (MV) time. Objective: To determine the incidence of VAP and its impact on the clinical course of the subject undergoing invasive MV in the ICU. Methods: This is a cohort study of hospitalized subjects in the general adult ICU of the State Hospital of Bauru / SP. The clinical information for the period of 19 months were collected. Stratification for the groups was based on the presence or absence of VAP, free_VAP and VAP, respectively. The Hotelling T² with 95% confidence, chi-square and the Mann-Whitney tests were executed using the "R" software and the results showed as mean ± standard deviation and absolute and relative distribution (p < 0.05). Results: The sample was of 322 subjects; the VAP group consisted of 73 (22.67%), 54.79% male, age: 62.31±16.96 years and the APACHE II: 29.98 ± 8.64. The VAP group had longer time of the MV and of the ICU compared to free VAP group; even in this group, the highest incidence of death in the ICU occurred between the 16th and 20th day of hospitalization. The free VAP group was older and 50% of the patients discharged from hospital. Conclusion: VAP and their interfaces still impact on the clinical evolution of the subjects mainly on the time factor of MV and ICU stay. The highest incidence of death in the ICU occurs in the first weeks.

Resumo Introdução: A Pneumonia Associada à Ventilação Mecânica (PAV) é uma complicação comumente encontrada na Unidade de Terapia Intensiva (UTI) e está associada à maior mortalidade, tempo de internação e ventilação mecânica (VM). Objetivo: Verificar a incidência da PAV e seu impacto sobre a evolução clínica dos sujeitos submetidos à ventilação mecânica invasiva na UTI. Métodos: Trata-se de um estudo de coorte com sujeitos internados na UTI geral adulto do Hospital Estadual de Bauru/SP. Foram coletadas as informações clínicas referentes ao período de 19 meses. A estratificação para os grupos foi realizada com base na ocorrência ou não da PAV, sem_PAV e PAV, respectivamente. Foi aplicado o teste T2 de Hotelling com 95% de confiança e Qui-Quadrado utilizando o Software "R" e os resultados apresentados em média ± desvio padrão e distribuição absoluta e relativa (p < 0,05).
