Background. Obesity has several effects on the mechanics of the rib cage that may impair the exercise performance of obese individuals and therefore impact the assessment of surgical risk. This study aimed to establish a reference value for the 6-minute walk distance (6 MWD) in obese Brazilian men in the preoperative period of bariatric surgery that considers the effect of lung function. Methods. This was a cross-sectional study in which 104 obese men underwent the six-minute walk test (6 MWT) before bariatric surgery. They also underwent the spirometry test and respiratory muscle strength measurement before the 6 MWT. Results. The 6 MWD was correlated with age (r = −0.388, p = 0.0005 ), weight (r = −0.365, p = 0.0007 ), height (r = 0.285, p = 0.022 ), body mass index (BMI) (r = −0.543, p < 0.0001 ), forced vital capacity (FVC) (r = 0.472, p < 0.0001 ), peak expiratory flow (r = 0.253, p = 0.031 ), and maximal inspiratory pressure (r = 0.313, p = 0.017 ). In the stepwise forward regression analysis, BMI, FVC, and age were the only variables that independently predicted the 6 MWD and explained 40% of its variability. The reference equation proposed for obese Brazilian men is 6 MWD (m) = 570.5 − (3.984 × BMIkg/m2) + (1.093 × FVC%predicted) − (0.836 × ageyrs). Conclusion. In this sample of obese Brazilian men, lung function contributed to poor performance in the 6 MWT. In these individuals, BMI, FVC, and age were the variables that composed the reference equation for the 6 MWD. Thus, in several clinical settings, such as in the evaluation before bariatric surgery, pulmonary function data are important to determine the reference value for the 6 MWD.

ABSTRACT The six-minute walk test (6MWT) is widely used to measure functional capacity in special populations. However, the factors associated with its performance in candidates for bariatric surgery are unclear. Therefore, this study aimed to investigate the influence of anthropometric and physiological factors in the 6MWT performance in bariatric surgery candidates. This cross-sectional study included 107 candidates for bariatric surgery. Anthropometric factors considered: gender, weight, height, body mass index (BMI), waist-to-hip, and waist-to-height ratios. Along with distance covered during 6MWT, physiological factors such as ratings of perceived exertion (RPE) and heart rate reserve percentage used (%HRR) were recorded. Among the 107 patients (mean age: 39.6 years), 83 volunteers were accepted to perform the 6MWT. No gender differences were observed in terms of distance covered, %HRR, and RPE during the 6MWT. Moreover, BMI and %HRR explained 21% of the 6MWT distance covered. Furthermore, participants with BMI ≤41.5 kg/m2 walked ~50 meters more than their peers above this level (p=0.05). Interestingly, heart rate increase during the 6MWT was lower than described for healthy populations. BMI and %HRR partially explain the variability of the 6MWT performance in bariatric surgery candidates.

Background: Six minute walk test (6MWT) is a sub-maximal exercise test, used as a clinical indicator of the functional capacity, in patients with cardiopulmonary diseases. It is simple, objective and reproducible test. The present study was designed to assess correlation of six minute walk test with spirometry parameters, in patients with chronic obstructive pulmonary disease.Methods: In this cross sectional study, fifty patients diagnosed with chronic obstructive pulmonary disease (GOLD criteria) coming to tertiary center were recruited according to inclusion and exclusion criteria. All patients underwent spirometric measurement. Spirometric indices including FEV1, FVC, FEV1/FVC and MVV were tested using computerized spirometer. 6MWT was performed following American Thoracic Society (ATS) guidelines. Percent (%) predicted 6MWD was calculated. Correlation between spirometry and 6MWT was assessed.Results: It was found that correlation between 6MWT and spirometry is statistically significant. There is significant strong positive correlation between percent predicted 6MWD and FEV1 (r=0.850 and p= <0.001), whereas there is significant moderate correlation between percent predicted 6MWD and FVC (r=0.554 and p= <0.001), FEV1/FVC (r=0.509 and p= <0.001) and MVV (r=0.615 and p= <0.001).Conclusions: In chronic obstructive pulmonary disease, percent predicted 6mwd significantly correlated with the spirometry parameters (FEV1, FVC, FEV1/FVC, and MVV). 6MWD decreases as there is decline in the pulmonary function. 6MWT can be a useful replacement of spirometry in assessment of severity of COPD.

COVID-19 ARDS has a high mortality and few therapeutic options. We present a preliminary report on our experience using high-dose pulsed methylprednisolone in COVID-19 ARDS and three-month outcomes. We performed a retrospective analysis of all patients treated with high-dose methylprednisolone for COVID-19 ARDS and three-month lung function, 6MWT, and CT findings. 15 patients were treated of which 10 survived to discharge. Reduced DLCO was the commonest abnormality in lung function tests and had the lowest mean value. Parenchymal bands were the commonest CT finding and 50% of patients had fibrosis at three-months. Mean 6MWD was 65.4% predicted and was abnormal in 62.5% of patients. In this cohort of patients with COVID-19 ARDS treated with high-dose methylprednisolone pulses, CT, lung function, and 6MWT abnormalities were unsurprisingly common at three months, although all 10 patients treated early in their disease course survived, a possible therapeutic effect. Further randomised controlled trials are needed to assess the benefits of this treatment.

Diabetes mellitus (DM) is a metabolic disease with characteristics of hyperglycemia due to abnormalities of insulin secretion, insulin action or both. DM is a risk factor for Peripheral Artery Disease (PAD). PAD is a progressive narrowing process of peripheral arteries, especially in the inferior limb arteries. As a result, there is a reduction in blood flow to the affected limb. Most patients do not show symptoms, but many also experience intermittent claudication. PAD can be diagnosed and its severity assessed using the Ankle Brachial Index (ABI) Score. PAD can cause disturbances in muscle mass and strength so that it can cause limitations in walking ability including gait, walking speed, and balance which ultimately impair Six Minute Walk Test (SMWT). The purpose of this study was to see whether there is an effect of decreasing ABI Score on distance covered during SMWT in diabetic patients. This study was analytic observational with a cross sectional study design using primary data and secondary data from DM patients who have never been diagnosed with PAD in Polyclinic of Muhammadiyah Hospital in Palembang. The sample size in this study was 40 patients with type 2 DM who were selected using nonprobability sampling with consecutive sampling method. The subject have their ABI and SMWT measured. The collected data was analyzed by chi-square test. In this study, the significance value was p = 0.016 (p <0.05) which can be concluded that there was an effect of decreasing ABI score on distance during SMWT in DM patients

Background: In COPD patients it is very important to assess the activities of daily living (ADL) due to an impairment of independence and quality of life. There is a lack of retrievable data regarding the cardio-pulmonary response to Londrina ADL protocol in patients with COPD. The aim of the present study was to assess the cardio-pulmonary response to Londrina ADL protocol in patients with COPD and to compare this with responses to the Glittre ADL test. Methods: This cross-sectional study was done on 30 COPD subjects. Each subject was made to perform the Londrina ADL protocol, Glittre ADL test, twice each, on subsequent days. The Londrina ADL protocol comprises 5 activities representing ADL, involving upper limbs, lower limbs, and trunk movements. The Glittre ADL test consists of completing a circuit while carrying a weighted backpack (2.5 kg for women, 5.0 kg for men). The better value of the two was taken into consideration. For the Londrina ADL protocol and Glittre ADL test the outcome of primary interest was time and for the six-minute walk test was the distance walked. The secondary outcomes for all the tests were heart rate, systolic blood pressure, diastolic blood pressure, respiratory rate, saturation of oxygen in blood and dyspnea.Results: The COPD subjects of age group 63.27±11.07 years took 5.94±0.36 min to complete trial 2 of the Londrina ADL protocol. A significant physiological increase in heart rate (p≤0.01), respiratory rate (p≤0.01), blood pressure (p≤0.01) and severity of dyspnea (p≤0.01) were observed whereas saturation of oxygen in blood (p≤0.01) was reduced at the end of the Londrina ADL protocol and Glittre ADL test. There was a positive, non-significant correlation between the six-minute walk test distance and the Londrina ADL protocol time (r=0.236) (p=0.209). A positive, not significant correlation was observed between the Glittre ADL test (time) and the Londrina ADL protocol (time) (r=0.194) (p=0.304) and a negative but not significant correlation between the six-minute walk test (distance) and the Glittre ADL test (time) (r= -0.184) (p=0.330).Conclusion: The Londrina ADL protocol can be used as an assessment tool to the evaluation of functional performance and activities of daily living in COPD along with other test protocols in pulmonary rehabilitation.

Pasien diabetes melitus sangat rentan terkena komplikasi akibat hiperglikemia yang dialami. Semakin lama pasien diabetes melitus mengalami hiperglikemia maka dapat menyebabkan berbagai macam komplikasi baik komplikasi mikrovaskular dan juga komplikasi makrovaskular seperti cardiovascular disease, coronary heart disease, heart failure dan lain-lain, meskipun komplikasi tersebut juga dipengaruhi faktor lain seperti diet dan juga pengobatan. Komplikasi makrovaskular pada diabetes melitus dapat menyebabkan penurunan kapasitas fungsional. Penurunan kapasitas fungsional tersebut salah satunya dapat diukur dengan menggunakan six minute walk test. Penelitian ini bertujuan untuk mengetahui hubungan antara lamanya menderita diabetes melitus terhadap jarak yang ditempuh selama six minute walk test. Penelitian ini bersifat analitik observasional dengan desain cross sectional study dengan besar sampel sebanyak 40 orang yang dipilih menggunakan nonprobability sampling dengan metode consecutive sampling. Hasil uji Chi-square didapatkan tidak terdapat hubungan antara lama menderita DM terhadap jarak yang ditempuh selama six minute walk test dengan nilai signifikannya adalah 0,69 (p>0,05).
