A prospective study of the influence of the skeleton on calcium mass transfer during hemodialysis.

Background: Calcium gradient, the difference between serum calcium and dialysate calcium d[Ca], is the main contributor factor influencing calcium transfer during hemodialysis. The impact, however, of bone turnover, on calcium mass transfer during hemodialysis is still uncertain.

Methods: This prospective cross-sectional study included 10 patients on hemodialysis for a 57.

Early postoperative parathormone sampling and prognosis after total parathyroidectomy in secondary hyperparathyroidism.

Introduction: There is possibility of a supernumerary hyperplastic parathyroid gland in dialysis patients after total parathyroidectomy and autograft in dialysis patients.

Objective: To test if the early postoperative measure of parathyroid hormone (PTH) can identify persistent hyperparathyroidism.

Methods: A prospective cohort of dialysis patients submitted to parathyroidectomy had PTH measured up to one week after operation.

The deceptive concept of hypoparathyroidism and recurrence after parathyroidectomy in dialysis patients: are we offering a Procrustean bed to some patients?

Objective:: to analyze the frequency of hypoparathyroidism and of its recurrence after parathyroidectomy in dialysis patients according to different existing classifications.

Methods:: we conducted a retrospective study of 107 consecutive dialysis patients undergoing total parathyroidectomy with immediate autograft in a tertiary hospital from 2006 to 2010. We studied the changes in PTH levels in the postoperative period over time.

Parathyroidectomy improves survival in patients with severe hyperparathyroidism: a comparative study.

Background And Objectives: Secondary hyperparathyroidism (SHPT) in CKD is associated with an increased risk for mortality, but definitive data showing that parathormone control decreases mortality is still lacking. This study aimed to compare the mortality of patients with severe SHPT submitted to parathyroidectomy(PTX) with those who did not have access to surgery.

Methods: This is a retrospective study in a cohort of 251 CKD patients with severe SHPT who were referred to a CKD-MBD Center for PTX from 2005 until 2012.

Phosphorus is associated with coronary artery disease in patients with preserved renal function.

High serum phosphorus levels have been associated with mortality and cardiovascular events in patients with chronic kidney disease and in the general population. In addition, high phosphorus levels have been shown to induce vascular calcification and endothelial dysfunction in vitro. The aim of this study was to evaluate the relation of phosphorus and coronary calcification and atherosclerosis in the setting of normal renal function.

Influence of asymptomatic histologic prostatitis on serum prostate-specific antigen: a prospective study.

Objectives: To determine the influence of asymptomatic inflammatory processes of the prostate on serum prostate-specific antigen (PSA) levels.

Methods: A total of 51 patients with no evidence of prostate cancer or clinical prostatitis were prospectively studied. All subjects underwent 10 to 12 sector transrectal-ultrasound guided needle biopsies of the prostate.

Praying correlates with higher quality of life: results from a survey on complementary/alternative medicine use among a group of Brazilian cancer patients.

Context: The use of complementary/alternative medicine has been little studied in Brazil.

Objective: The purpose of this study was to determine the prevalence of complementary/alternative medicine use among a group of Brazilian cancer patients and correlate these findings with the patients' quality of life.

Type Of Study: Descriptive.
