Background:Patent ductus arteriosus (PDA) is a common cause of morbidity in premature neonates. The purpose of this study was to compare the efficacy of oral ibuprofen and oral acetaminophen to closure of symptomatic PDA, in premature neonates with gestational age (GA) ≤32 weeks.Materials and Methods:This study was a randomized clinical trial with forty preterm neonates who were admitted in neonatal intensive care unit with symptomatic PDA and GA ≤32 weeks or birth body weight ≤1500 g. Twenty neonates received oral acetaminophen [Group A] and twenty neonates received oral ibuprofen [Group B] and compared with echocardiography finding each groups for closed PDA before and after treatment regiment.Results:Our results showed that the primary closure rate of PDA was 70% (95% confidence interval [CI]: 49.9%–90%) and 65% (95% CI: 54.3%–75.7%) in the acetaminophen and ibuprofen groups, respectively, and statistically no significant difference was observed between the two groups (P = 0.74).Conclusion:These findings suggest that there was no significant difference between the effectiveness of oral acetaminophen and oral ibuprofen on closing of PDA, but less adverse effects and contraindication for acetaminophen make it reasonable choice for the treatment of symptomatic PDA.

Background:The significant association between epicardial adipose tissue and cardiovascular risk factors as well as outcome of ischemic heart diseases has been recently proposed. We determined the association between epicardial adipose tissue thickness and in-hospital as well as 3-month outcome after coronary artery bypass grafting surgery (CABG).Materials and Methods:This cross-sectional study was performed on 78 consecutive patients who underwent CABG in our heart center. Associations between epicardial adipose tissue thickness and in-hospital as well as 3-month outcome after CABG were measured by logistic regression and value of epicardial fat thickness evaluated by receiver operating characteristic (ROC) curve analysis.Results:Patients in-intensive care unit (ICU) suffered a variety of events, which many of them were insignificant, but 23 events (29.4%) of 78 were considered as important. The most frequent complication occurred in ICU was atrial fibrillation (9%). The frequency of 3-month complications was 6.4%, including 3.8% rehospitalization, 1.3% reoperation, and 1.3% cardiac death. Ninety-day mortality rate was 1.3%. Mean epicardial adipose tissue thickness was significantly higher in those with in-ICU complications than those without complication (7.64 ± 2.80 mm vs. 6.16 ± 2.29 mm, P = 0.015); however, the difference for 90-day complications was statistically nonsignificant. According to ROC curve analysis, measuring epicardial adipose tissue thickness could moderately predict in-ICU complication (area under the curve = 0.65 8, 95% confidence interval: 0.536–0.779, P = 0.017). The best cut-off point of this adipose tissue thickness for predicting in-ICU complication was 6.5 mm with sensitivity of 65.9% and specificity of 58.8%.Conclusion:Epicardial adipose tissue thickness is a useful predicting parameter for in-ICU complications after CABG.
