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: 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.

AbstractIntroduction The purpose of the six-minute walk test (6MWT) is to evaluate cardiopulmonary capacity using a low-cost test that is easy to administer, generally well tolerated by different populations and reflects one’s performance on activities of daily living. However, few studies have been conducted to determine the difference between performing the 6MWT indoors and outdoors.Objective The aim of the present study was to compare the distance covered on the 6MWT performed indoors and outdoors and evaluate the following physiological variables: heart rate, blood pressure and the subjective sensation of shortness of breath, using the Borg perceived exertion scale.Materials and methods A prospective, randomized, clinical trial was conducted involving eight healthy females not engaged in regular physical activity, with mean age 23.75 ± 1.67 years. Each subject performed the 6MWT indoors and outdoors with a 30-minute interval between tests. The order of the tests was determined randomly.Results The mean distance traveled was 578 ± 50.07 m on the outdoor trial and 579.95 ± 45.35 m on the indoor trial (p = 0.932). The mean physiological variables were 82.25 ± 11.02 bpm (indoors) versus 84.38 ± 9.42 bpm (outdoors) for heart rate, 121.88 ± 10.28 mmHg (indoors)versus 118.75 ± 19.40 mmHg (outdoors) for systolic blood pressure, 81.88 ± 9.74 mmHg (indoors) versus 80.50 ± 7.89 mmHg (outdoors) for diastolic blood pressure and a mean score of 12 on the perceived exertion score in both environments.Conclusions The present data demonstrate no differences in the distance walked on the 6MWT or the physiologic variables of participants between the indoor and outdoor trials.

Diabetes Melitus

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).

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.

Background: Accurate risk stratification for untoward outcomes after acute coronary syndrome patients may help clinicians guide the type and intensity of therapy. Unfortunately, most of the Papuanese people face difficulties in accessing sophisticated medical treatment. Aims: The aim of this study was to determine the simplest but most accurate risk stratification for ACS patients treated in rural hospital. Methods: This was a cross-sectional study conducted in Sele Be Solu Regional Hospital at Sorong Regency in West Papua Province. Fifteen unselected patients from September 2019 to March 2020 period with ACS were prospectively studied. All the data were collected from medical records. Results: Subject characteristics mostly were male (80%) and mean age was 54 years, (13,3%) subjects were age less than 45 years. The most diagnosed ACS type was STEMI (73,3%). Conclusion:In Papuanese patients with ACS in rural hospital, those at highest risk can be identified using Killip classification and The Six-minute Walk Test Borg Scale as short term predictor for ACS patients’ outcome.
