Predictive validity analysis of six reference equations for the 6-minute walk test in healthy Brazilian men: a cross-sectional study

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: The 6-minute walk test (6-MWT) is commonly used to measure functional capacity in clinical and research settings. The reference equations for predicting the 6-minute walk distance (6-MWD) in different populations have been established; however, there is a lack of information regarding healthy Saudi individuals over 50 years old. OBJECTIVES: This study aimed to establish the reference values of 6-MWD in a sample of healthy Saudi adults aged 50–80 years, develop regression equations for the established 6-MWD, and compare the measured 6-MWD in the present study with the predicted 6-MWD derived from the previously published regression equations. METHODS: In total, 210 healthy Saudi volunteers aged 50–80 years participated in this cross-sectional study. The 6-MWT was performed according to the American Thoracic Society (ATS) guidelines. Lung function, physical activity, blood pressure, heart rate, oxygen saturation, exertion level of leg fatigue, and sensation of dyspnea were measured. RESULTS: The mean 6-MWD was 396.2 ± 69.4 m. It was significantly correlated with age, sex, height, body mass index (BMI), and physical activity. The predictors of 6-MWD were age and BMI for men, while they were age, BMI, and height for women. They accounted for 25% and 35% of the total variance of 6-MWD for men and women, respectively. The measured 6-MWD was significantly shorter than the predicted 6-MWD. CONCLUSION: Saudi populations have significantly shorter 6-MWDs than those reported in other ethnic groups. The sex-specific equations developed in this study are expected to provide a useful measure of 6-MWT for Saudi adults. However, further investigation is required to validate the application of these equations to individuals living in different regions of Saudi Arabia.

Background: Six minute walk test (6MWT), represent a useful marker for exercise capacity and dynamic hyperination of COPD patients.Highresolution computed tomography (HRCT) has allowed in detection of airway wall abnormalities and emphysema, whose extent may correlate with the clinical severity of the disease in COPD patients. Material & methods: A cross sectional study was carried in 100 COPD patients attending Department of Respiratory Medicine, Institute of respiratory diseases, SMS Medical College, Jaipur, during June 2018 to May 2019.All patients underwent clinically (Modied Medical Research Council), radiologically (HRCT) &6MWT. Results:The 6MWTshowed that a negative correlation to dyspnea (mMRC grading), emphysema score & post FEV1% predicted (p<0.0001). Conclusion:The HRCTemphysema score can be used as an initial parameter for identify patients with high risk for COPD.

Background: Many of the ILDs are difficult to differentiate on clinical examination and history as they have similar clinical features. Symptom complex is not beyond that of respiratory symptoms. The objective was to study the clinical picture and spirometry pattern of the patients having interstitial lung disease.Methods: Hospital based cross sectional study was carried out among 73 cases of ILDs. Data related to history, clinical examination was recorded. Six minute walk test and spirometry was carried out. The data was analysed using proportions.Results: Incidence of Idiopathic pulmonary fibrosis (IPF) increased with age. Exertional dyspnea (100%) and cough (95.9%) were the commonest presenting symptoms amongst ILD patients. End inspiratory fine crackles (95.1%) and clubbing (67.1%) are the predominant clinical signs. Mean BMI of various ILDs patients were 24.86±8.2 Kg/m² in NSIP followed by 22.9±4.6 in sarcoidosis 21.9±6.4 and 20.8±3.94 in IPF and in Cryptogenic Organizing Pneumonias 19.34±1.8 Kg/M². Serum ACE level was raised in 69.2% patients of sarcoidosis. 81 % of patients could successfully perform 6 Minute Walk Test. Among those who could perform, average desaturation was 8.11% in sarcoidosis, 7.52% in IPF, 6.0% In Hypersensitivity Pneumonitis, 5.75% in NSIP and 4.75% in CTD associated ILDs patients. Raised C Reactive Protein label was consistent (45.2%) in ILDs, maximum in HP (63%) and 2 out of 3 patients with COP and 3 out of 5 patients of CTD associated ILDs. 17.8% cases had positive serum ANA, maximum in IPF.Conclusions: Idiopathic pulmonary fibrosis (IPF) was the commonest Interstitial Lung disease present in 39.7% of 73 cases followed by sarcoidosis in 17.9%, cases.
