RESUMEN
OBJECTIVES: To test the hypothesis that neonatal supplementation with lutein in the first hours of life reduces neonatal oxidative stress (OS) in the immediate postpartum period. METHODS: A randomized controlled, double-blinded clinical trial was conducted among 150 newborns divided into control group, not supplemented (n = 47), and test group, supplemented with lutein on the first day postpartum (n = 103). Blood Samples were collected at birth from cord and at 48 hrs postpartum while routine neonatal metabolic screenings were taking place. Total hydroperoxide (TH), advanced oxidation protein products (AOPP), and biological antioxidant potential (BAP) were measured by spectrophotometry and data were analyzed by Wilcoxon rank sum test and by multivariate logistic regression analysis. RESULTS: Before lutein supplementation, the mean blood concentrations of AOPP, TH, and BAP were 36.10 umol/L, 156.75 mmol/H2O2, and 2361.04 umol/L in the test group. After lutein supplementation, significantly higher BAP increment (0.17 ± 0.22 versus 0.06 versus ± 0.46) and lower TH increment (0.46 ± 0.54 versus 0.34 ± 0.52) were observed in the test group compared to controls. CONCLUSION: Neonatal supplementation with lutein in the first hours of life increases BAP and reduces TH in supplemented babies compared to those untreated. The generation of free radical-induced damage at birth is reduced by lutein. This trial is registered with ClinicalTrials.gov NCT02068807.

BACKGROUND: In the literature good results have been reported for the treatment of Pseudomyxoma peritonei (PMP) by cytoreduction, peritonectomy and hyperthermic antiblastic peritoneal perfusion (H.A.P.P.). Forty-eight patients affected by PMP have been treated with this technique over the past ten years. PATIENTS AND METHODS: Peritoneal perfusion has been performed with the original semiclosed tecnique after complete surgical cytoreduction in 188 patients affected by peritoneal carcinomatosis. In 48 of the cases the patients were affected from PMP. Aggressive surgical cytoreduction was performed with multiple visceral resections and peritonectomies. RESULTS: Seventeen patients (38%) presented major perioperative complications, and in five cases the reoperation of the patient was required. In spite of this high complication rate, there was no perioperative mortality. The results of the Kaplan-Meier 5- and 10-year survival analysis, were 94% and 82%, respectively, with a disease-free survival of 80% at 5 years and 70% at 10 years. Thirty-nine patients (81.2%) had no evidence of disease at follow-up (range 1-120 months). DISCUSSION: Up to date, the most effective treatment for PMP has been aggressive cytoreduction plus H.A.P.P.
