Background: Assessment of quality of life (QOL) of end-stage renal disease (ESRD) patients (physical, mental, and social well-being) has become an essential tool to develop better plans of care. Objective of this study is to determine which demographic and biochemical parameters correlate with the QOL scores in patients with ESRD on hemodialysis (HD) using Kidney Disease QOL-36 surveys (KDQOL). Methods: A retrospective chart review of all ESRD patients who underwent HD at an outpatient center. The five components of the KDQOL were the primary end points of this study (burden of kidney disease, symptoms and problems, effects of kidney disease on daily life, mental component survey, and physical component survey). Scores were grouped into three categories (below average, average, and above average). In addition to demographics (age, sex, and race), the independent variables such as weight gain, number of years on dialysis, urea reduction ratio, calcium, phosphorus, parathyroid hormone, albumin, and hemoglobin in the serum were collected. Chi-square analysis for dependent variables and the nominal independent variables was used, and analysis of variance analysis was used for continuous independent variables. Ordinal regression using PLUM (polytomous universal model) method was used to weigh out possible effects of confounders. Results: The cohort size was 111 patients. Mean age was 61.8 (±15.5) years; there were more males than females (64.9% vs 35.1%), the mean time-on-dialysis at the time of the study was 4.3 (4.8) years. Approximately two-thirds of the responses on all five domains of the questionnaire ranked average when compared to the national numbers. The remainders were split between above average (20.6%) and below average (13.4%). In our cohort, no relationships were statistically significant between the five dependent variables of interest and the independent variables by chi-square-and t-test analyses. This was further confirmed by regression analysis. Of note, sex carried the strongest statistical significance (with a P-value of 0.16) as a predictor of "the burden of kidney disease on daily life" in ordinal regression. Conclusion: Prior studies have shown variables such as serum phosphate level, intradialytic weight gain, and dialysis adequacy are associated with lower KDQOL scores; however, this was not evident in our analysis likely due to smaller sample size. Larger size studies are required to better understand the predictors of QOL in ESRD patients on HD.

Study Type – Therapy (case series)
Level of Evidence 4 OBJECTIVE To describe a novel synchronous approach to apical dissection during robotic‐assisted radical prostatectomy (RARP) which augments circumferential visual appreciation of the prostatic apex and membranous urethra anatomy, and assess its effect on apical margin positivity. PATIENTS AND METHODS Positive surgical margins (PSM) during RP predispose to earlier biochemical recurrence, and occur most frequently at the prostatic apex. Conventional apical transection after early ligation of the dorsal venous complex (DVC) remains suboptimal, as this approach obscures visualization of the intersection between prostatic apex and membranous urethra, leading to inadvertent apical capsulotomy and eventual margin positivity. A synchronous urethral transection commenced via a retro‐apical approach was adopted in 209 consecutive patients undergoing RARP by one surgeon (A.T.) between April to September 2009. The apical margin rates for this group were compared with those of 1665 previous patients who received conventional urethral transection via an anterior approach after DVC ligation. Outcomes were adjusted for differences in clinicopathological variables. All RP specimens were processed according to institutional protocols, and examined by dedicated genitourinary pathologists. The location of PSMs was identified as apex, posterior, posterolateral, bladder neck, anterior, base, or multifocal. RESULTS Patients receiving synchronous urethral transection had significantly lower apical PSM rates than the control group (1.4% vs 4.4%, P= 0.04). This marked improvement in the retro‐apical group occurred despite a significantly higher incidence of aggressive cancer (≥pT3a) documented on final specimen pathology (16% vs 10%, P= 0.027).Technical difficulty was encountered in three of 209 study patients, in whom urethral transection had to be completed using the classic anterior approach. CONCLUSION Improved circumferential visualization of the prostatic apex, membranous urethra and their anatomical intersection facilitates precise dissection of the apex and its surrounding neural scaffold, and optimizes membranous urethral preservation. This has significantly ameliorated apical PSM rates in patients undergoing RARP, despite having to deal with more aggressive cancer on final specimen pathology.

BACKGROUNDAcute upper gastrointestinal bleeding (AUGIB) is a frequently encountered condition in the Gastroenterology field with a mortality rate of 10-14%. Despite recent newer innovations and advancements in endoscopic techniques and available medications, the mortality rate associated with AUGIB remained persistently elevated.AIMTo explore mortality, characteristics and outcome differences between hospitalized patients who develop AUGIB while in-hospital, and patients who initially present with AUGIB.METHODSThis is a retrospective of patients who presented to Northwell Health Staten Island University Hospital from October 2012 to October 2016 with AUGIB that was confirmed endoscopically. Patients were divided in two groups: Group 1 comprised patients who developed AUGIB during their hospital stay; group 2 consisted of patients who initially presented with AUGIB as their main complaint. Patient characteristics, time to endoscopy, endoscopy findings and interventions, and clinical outcomes were collected and compared between groups.RESULTSA total of 336 patients were included. Group 1 consisted of 139 patients and group 2 of 196 patients. Mortality was significantly higher in the 1st group compared to the 2nd (20% vs 3.1%, P ≤ 0.05). Increased length of stay (LOS) was noted in the 1st group (13 vs 6, P ≤ 0.05). LOS post-endoscopy, vasopressor use, number of packed red blood cell units and patients requiring fresh frozen plasma were higher in group 1. Inpatients were more likely to be on corticosteroids, antiplatelets and anticoagulants. Conversely, the mean time from bleeding to undergoing upper endoscopy was significantly lower in group 1 compared to group 2.CONCLUSIONIn-hospital AUGIB is associated with high mortality and morbidity despite a shorter time to endoscopy. Larger scale studies assessing the role of increased comorbidities and antithrombotic use in this setting are warranted.
