ObjectivesIndividuals with chronic obstructive pulmonary disease (COPD) are usually > 50 years of age and have a low body mass index (BMI). An imbalance between matrix metalloproteinases (MMPs), including MMP-3, and tissue inhibitor of metalloproteinase 1 (TIMP-1), play a role in tissue degradation of lung extracellular matrix among COPD individuals. The purpose of the present study was to correlate age and/or BMI with salivary levels of MMP-3 and TIMP-1 among Indonesian subjects with COPD.ResultsThirty COPD patients were recruited to undergo thorough physical assessment and saliva collection for evaluating TIMP-1 and MMP-3 levels using commercially available kits enzyme-linked immunosorbent assay method. The mean (standard deviation) participant age and BMI were 60.5 (8.13) years, and 23.1 (4.75) kg/m2, respectively. Furthermore, the mean (standard deviation) of TIMP-1 and MMP3 levels were 23.99 (6.85) ng/mL and 1.81 (1.167) μM, respectively. Age was negatively correlated with MMP-3 (P < 0.05), but not with TIMP-1 levels. Age and BMI were not correlated with TIMP-1 level (P > 0.05). Collectively, this study demonstrated that age has a negative correlation with the protease marker (i.e. MMP-3), but not the anti-protease marker (TIMP-1). BMI was not correlated with either protease/anti-protease marker among Indonesian subjects with COPD.

Introduction: Chronic obstructive pulmonary disease (COPD) is a chronic inflammation that causes a variety of pulmonary and systemic disorders. Pursed-lip breathing and diaphragmatic breathing exercises are useful techniques for improving ventilation, reducing the degree of breathlessness, enhancing performance, and improving quality of life. The aim of this study was to determine the effect of pursed-lip breathing and diaphragmatic breathing exercise on the value of the 6-min walk test and to improve quality of life by SGRQ in stable COPD patients. Methods: This study was an experimental study using group control before and after examining 60 stable COPD patients at Dr. RSUD Lung Center. Zainoel Abidin from November 2019 to February 2020. Samples were extracted by systematic random sampling and divided into two groups. The intervention group received indacaterol bronchodilator therapy in addition to four weeks of apron and diaphragmatic breathing exercises. The control group received only indacaterol therapy. A 6-minute walk test was administered and a quality of life questionnaire was completed using the SGRQ. A t-test and Wilcoxon test were performed to assess differences between groups, level of significance p < 0.05). Results: There was a significant effect on the 6-minute walk test in the intervention group compared with the control group (p = 0.001). There was a significant effect in improving quality of life using the SGRQ questionnaire in the intervention group compared with the control group (p = 0.001). Conclusion: There was a significant effect on the six-minute walking test in the intervention group compared to the control group. There was a significant effect on improving the quality of life using the SGRQ questionnaire in the intervention group compared to the control group.

Latar Belakang: Asma merupakan suatu penyakit yang bersifat heterogen dan ditandai oleh inflamasi saluran napas kronik dengan gejala mengi, sesak napas, dada terasa berat, dan batuk yang bervariasi dalam intensitas dan waktu serta disertai dengan keterbatasan aliran udara ekspirasi yang bervariasi. Pasien asma mengalami penurunan fungsi paru yang berlangsung di saat serangan asma yang disertai dengan peningkatan kadar fractional-exhaled nitric oxide (FeNO) yang diakibatkan oleh proses patofisiologi asma dan gangguan ventilasi yang terjadi. Penelitian ini bertujuan untuk mengetahui gambaran fungsi paru dengan spirometri dan kadar FeNO pada pasien asma rawat jalan.
