OUTCOMES OF THE WEIGHTED PERITONEAL DIALYSIS CATHETER IN PATIENTS AT RISK OF PERCUTANEOUS CATHETER FAILURE.
BACKGROUND
The weighted catheter has shown promising results in retrospective and randomized studies. We examined its usefulness in patients with previous failed non-weighted peritoneal dialysis (PD) catheters or previous abdominal surgery.
METHODS
The insertion, start, end, and removal dates were recorded for all-type catheter insertions from 2011 to 2016. Primary and secondary failure rates were recorded, defined as failure to ever establish flow (primary) or failure after a period of successful PD (secondary). Patients were censored from analysis if PD ended due to death, transfer of care, transfer to hemodialysis, transplantation, or if the patient recovered renal function.
RESULTS
There were 44 weighted, 75 non-weighted open surgical, and 143 percutaneous catheters. There was previous abdominal surgery in 29% and 6% of patients receiving surgically inserted and percutaneous catheters, respectively (p < 0.0001). Primary failure rates were 4/44 (9%), 20/75 (27%), and 26/143 (18%) in weighted, non-weighted surgical, and percutaneous catheters, respectively. There were reduced primary and secondary failure rates in the weighted (9% primary and 15% secondary) versus non-weighted surgically inserted group (27% primary and 46% secondary) (p = 0.04). There was no difference between primary (p= 0.15) and secondary (p = 0.5) failure rates between weighted and percutaneously inserted catheters. Kaplan-Meier survival analysis revealed overall increased catheter survival in the weighted group (p = 0.02).
CONCLUSION
Weighted catheters were associated with increased survival and decreased failure rates compared with non-weighted surgical catheters, despite usage in patients at higher risk of catheter failure due to previous failed catheters and abdominal surgery

Vitamin D deficiency is associated with a worse prognosis in metastatic melanoma
Vitamin D deficiency (≤20 ng/mL) is associated with an increased incidence and worse prognosis of various types of cancer including melanoma. A retrospective, single-center study of individuals diagnosed with melanoma from January 2007 through June 2013 who had a vitamin D (25(OH)D3) level measured within one year of diagnosis was performed to determine whether vitamin D deficiency and repletion are associated with melanoma outcome. A total of 409 individuals diagnosed with histopathology-confirmed melanoma who had an ever measured serum 25(OH)D3 level were identified. 252 individuals with a 25(OH)D3 level recorded within one year after diagnosis were included in the study and the individual and melanoma characteristics such as age, sex, Breslow thickness, ulceration, stage, mitotic rate, and LDH were obtained from the medical record. A worse melanoma prognosis was associated with vitamin D deficiency (P=0.012), higher stage (P20 ng/mL increase. Our results suggest that initial vitamin D deficiency and insufficient repletion is associated with a worse prognosis in patients with metastatic melanoma
