IntroductionThe benefit of surfactant prescription for respiratory distress syndrome (RDS) has been approved. Curosurf and Survanta are two commonly used natural surfactants in Iran. Previous studies did not report priority for one of these two drugs. The present study aimed to compare the effectiveness and safety of Curosurf and Survanta in treatment of RDS.MethodsIn this randomized clinical trial, neonates were born with RDS diagnosis in two governmental and referral hospitals of Tehran (the capital of Iran) in 2014 were randomly selected. Neonates were randomly assigned into two groups receiving 100 mg/kg Curosurf or Survanta as soon as possible after randomization. Complications, mortality and needing the second dose were compared between the two groups.ResultsA total 112 patients with the mean gestational age of 32.59 ± 3.39 weeks were evaluated (56 patients in each group). There were no significant differences regarding birth weight, gestational age, delivery method, and parity between the two groups (P > 0.05). The complications were occurred in 18 neonates (32.1%) of Curosurf group and 20 neonates (35.7%) of Survanta group (RR = 0.922, 95% CI = 0.617–1.379). There were no significant differences regarding complications, mortality, and needing nasal CPAP and endotracheal tube between the two groups. In the neonates with gestational age of 29–32 weeks the IVH and NEC incidence were significantly more in Curosurf group compared to Survanta group (27.8% vs 0% and 22.3% vs 0%, P < 0.05).ConclusionThere was no significant difference in complications or mortality between those two groups; however Curosurf was associated with less need of ET tube (in >32 birth weeks subgroup) and NCPAP (in 29–32 birth weeks subgroup) (p = 0.008). Further evaluations with longer follow-up duration are needed for comparing these two surfactants.

Objectives: The aim was to investigate the effect of hepatitis C virus (HCV) infection treatment with direct-acting antiviral (DAA) drugs on patients' mood, sleep quality and quality of life (QoL). Methods: Chronic HCV-infected patients receiving DAAs were evaluated prospectively. Patients were evaluated before the beginning of treatment and 12e24 weeks after finishing their treatment duration using the Pittsburgh Sleep Quality Index, Beck depression inventory questionnaire and SF-36 healthrelated QoL questionnaires. Results: A total of 120 patients with a mean age of 41.03 ± 7.68 years were evaluated (68.3% males). The mean follow-up duration was 141.79 ± 27.88 days after finishing the treatment. Significant improvement in the scores of sleep quality (5.13 ± 1.5 vs. 3.43 ± 1.35), mood (12.77 ± 4.02 vs. 9.27 ± 3.14) and QoL (77.49 ± 5.15 vs. 83.95 ± 3.39) post treatment compared with pretreatment were observed (p < 0.05). Changes in patients' sleep and mood were not related to their QoL change (p > 0.05). Discussion: DAAs for the treatment of HCV have a significant effect on improving their sleep, mood and QoL. The changes in sleep quality, mood and QoL of patients were independent and were not affected by each other.
