conclusions this study indicated that the rv systolic strain and strain rate can be used to detect early rv systolic dysfunction in ssc patients without pulmonary hypertension. these parameters may be useful for the provision of a more adequate management of ssc patients. results in the ssc patients, the rv strain (- 19 ± 10 vs. - 25 ± 4 %; p = 0.004) and the systolic strain rate (- 1.3 ± 0.5 v...

introduction: today, temporary or permanent venous catheters are being increasingly used in patients with renal failure. it seems a necessity to be familiar with their clinical applications and complications as well as their efficacy. the aim of this study was to compare the efficacy of two catheters of 16 cm and 20 cm lengths. methods: this research project was a descriptive, analytic study co...

Thus, we are faced with an asthma paradox; asthma is diagnosed subjectively by clinical history and treated with biologically active drugs. To solve this paradox, we need objective airway biomarkers to tailor the proper medica...
