Blood pressure control with active ultrafiltration measures and without antihypertensives is essential for survival in hemodiafiltration and hemodialysis programs for patients with CKD: a prospective observational study.

Background: High blood pressure is a prevalent condition in patients with chronic kidney disease on hemodialysis. Adequate control of high blood pressure is essential to reducing deaths in this group. The present study aimed to observe mortality prospectively in a group of patients in hemodialysis and hemodiafiltration programs in whom the use of antihypertensives was optimized with the point-of-care dry weight (POC-DW) technique.

Predictive equation of metastasis in patients with malignant ovarian epithelial tumors with the Ca-125 marker.

Background: Cancer antigen (CA) 125 (CA-125) is used in ovarian cancer detection and monitoring, whose serum level has a positive correlation with tumor stage. The aim of this study was to obtain a prediction metastasis equation in a group of patients with ovarian cancer based on Ca-125.

Methods: A 2-group comparative observational study was conducted at a single oncologic institution (SOLCA) in Cuenca-Ecuador.
