Abstract

Backgrounds: In recent years, circulating tumor DNA (ctDNA) has emerged as a specific and sensitive blood-based biomarker to detect EGFR mutations. This study aims to determine the diagnostic accuracy of ctDNA in detecting EGFR gene mutations in adenocarcinoma lung cancer. Methods: This study was a cross-sectional study with the subjects were adenocarcinoma lung cancer patients from histopathology or cytology examination and examined EGFR mutations from plasma tissue biopsy and ctDNA specimens from April 2018 to February 2019 in several hospitals in the Medan City. Results: There were 100 data have been collected, with male were 71 subjects and female were 29 subjects. Found 20 mutations, single mutations of tissue biopsy were 19 cases, del exon 19 were 12 cases, mutation in exon 21 (L858R) were 6 cases, mutation exon 21 (L861Q) was 1 case, del exon 19 and 21 (L861Q double mutations) was 1 case. From plasma ctDNA examination EGFR mutations were found 15 cases, del exon 19 were 12 cases and del exon 21 (L858R) were 3 cases. Conclusions: The highest proportion of EGFR mutations by sex were women from tissue biopsy or ctDNA, the most often frequency of EGFR mutations from tissue biopsy and ctDNA in single mutations and exons19.

Abstract

Background: Tuberculous pleural effusion is a paucibacillary manifestation of tuberculosis, so isolation of Mycobacterium tuberculosis is difficult, biomarkers being an alternative for diagnosis. Adenosine deaminase has the potential to optimize the diagnostic approach of tuberculous pleural effusion. Methods: This study is a diagnostic test observational (cross-sectional), which included 35 inpatient samples that meet inclusion and exclusion criteria from H. Adam Malik Medan General Hospital. Research began on February 1st until July 31st 2016 to examine 10 cc of pleural fluid specimens for the levels of Adenosine deaminase. Results: There are significant differences in the levels of adenosine deaminase from tuberculous and non-tuberculous pleural effusion (P=0.001). In the cut-off point 36.55 IU/L, level of sensitivity 95.8%, specificity 90.99%, positive predictive value 95.8%, negative predictive value 90.99%, and accuracy 94.2% of pleural fluid adenosine deaminase level test in tuberculous pleural effusion. Conclusion: Adenosine deaminase pleural fluid can be a diagnostic modality that is easy, fast, relatively affordable and applicable in the diagnosis of tuberculous pleural effusion.

Abstract

Background: Patients with COPD exhibit muscle atrophy and dysfunction which lead into decondition state. This will in turn decrease maximal oxygen uptake (VO2 max) in tissues. Considered as the best predictor of cardiorespiratory endurance and survival, VO2max can be attenuated by aerobic training. This study aimed to assess the effects of lower-limb endurance training on VO2 max in COPD patient. Methods: An experimental study was conducted on 20 COPD patients in group C and D in June–July 2017 at USU Hospital. Patients were prescribed lower-limb exercise by stationary cycling with individualized dose, twice a week for 4 weeks, ranging from 5-20 minutes/session. VO2 max measurement was calculated pre-and post-intervention using Nury’s Formula specifically designed for Indonesian (r=0,68; P
