Prostate-specific Antigen at 3 Months as a Predictor of Radiologic Progression-free Survival in Metastatic Hormone-sensitive Prostate Cancer Treated with Apalutamide: Analysis of 633 Patients in a Real-world Database.

Background And Objective: The depth of the prostate-specific antigen (PSA) decline after androgen receptor pathway inhibitor (ARPI) treatment combined with androgen deprivation therapy for patients with metastatic hormone-sensitive prostate cancer (mHSPC) may affect prognosis. The primary objective in our study was the correlation between the PSA response at 3 mo and radiologic progression-free survival (rPFS) at 24 mo. Three groups were defined according to the PSA decline: complete response (PSA ≤0.

[Effect of partially refined palm oil in lipid profile in rats].

Palm oil is rich in carotenoids, tocopherols and tocotrienols. This oil is refined for its human consumption bringing as a consequence an alteration of their properties. The objective of this study was to evaluate the effect of the partially refined, bleached and deodorized palm oil (RBD red) on the lipid profile and levels of vitamin A (retinol) and E (alpha tocopherol) in 4 groups of rats: B (commercial food Protinal for laboratory animals: ST + 5% egg yolk powder); C (ST + 5% egg yolk powder + 14 RBD red) both groups with induced hyperlipidemia; and D (ST + 14% RBD red), as compared with a control A (ST) during 35 days.

A study about the effect of vitamin E on hyperlipidemia and atherosclerotic lesions in New Zealand white rabbits fed with a 1% cholesterol rich diet.

The purpose of this study was to determine whether the administration of Vitamin E (200 mg/day) for 4 weeks could decrease hypercholesterolemia and inhibit atherosclerosis in male hypercholesterolemic New Zealand White rabbits. Plasmatic Total Cholesterol (TC) and LDL-Cholesterol (LDLc) were determined by enzymatic methods and Vitamin E was determined in plasma by HPLC at weeks 0, 4 and 8. A histopathological study was carried out at week 8 (w 8), using a hematoxylin-eosin method.

[Serum levels of vitamin C in young adults who chronically use drugs of abuse].

Few studies have evaluated the relationship between drugs of abuse consumption and plasma levels of vitamin C. Because of the importance of vitamin C due to its role in prevention of acute and chronic diseases, this study was carried out with the purpose of testing the influence of consumption of drugs of abuse on the plasmatic levels of vitamin C (ascorbic acid) of 56 male chronic users of drugs of abuse with an age range of 16 to 40 years. The following was performed: 1) A survey of consumption to determine the kind, frequency and quantity of drug(s) used and 2) The plasmatic levels of vitamin C in fasting condition, using the Rue and Kuether method.
