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.
The advent of prostate-specific antigen screening has changed the global epidemiology of prostate cancer, with men being diagnosed with organ-confined cancer at a younger age. Radical prostatectomy with curative intent for these patients, while delivering excellent long-term survival outcomes, still has significant side effects, chiefly postprostatectomy incontinence. Increasing age, shorter pre- and post-operative membranous urethral length, anastomotic strictures, obesity, low surgeon volume, variations of surgical technique and previous prostate surgery have been reported as negative risk factors for delayed continence recovery and/or permanent incontinence following radical prostatectomy. Significant progress in elucidating the functional anatomy and physiology of the male continence mechanism from cadaveric and videourodynamic studies have enabled surgeons to propose innovative surgical techniques during radical prostatectomy for augmenting continence preservation and early return. These have included optimizing the preservation of urethral rhabdosphincter length; avoiding rhabdosphincter injury; posterior reconstruction of Denonvilliers' musculofascial plate; preservation of the bladder neck and internal sphincter; bladder neck intussusception; bladder neck mucosal eversion; preservation of the puboprostatic ligaments and arcus tendineus; and preservation of putative nerves supplying the continence mechanism. We review the scientific and technical advances in continence recovery following radical prostatectomy, identify the key principles undergirding early return of continence, highlight various treatment strategies for early and refractory postprostatectomy incontinence and describe our experience with a paradigm of these unified key principles. Increasing application of these principles in computer-aided (robotic), minimally invasive and minimal-access (i.e., single-port or natural orifice transluminal) approaches will hopefully enable patients to derive maximal benefit from curative prostatectomy while experiencing early return of continence in the not too distant future.
ObjectiveTo determine whether the severity of erectile dysfunction (ED) in a man diagnosed with late-onset hypogonadism (LOH) gives information about his metabolic syndrome state, as patients with LOH often have sexual symptoms and associated cardiovascular and metabolic comorbidities, but the role of ED in predicting the prevalence of comorbid disease in men with low levels of testosterone is currently unknown.Patients and methodsMen (130) diagnosed with LOH and fulfilling the criteria of a total testosterone level of <3.5 ng/mL (<12 nmol/L), and with an erectile function domain score of <21 on the International Index of Erectile Function questionnaire (IIEF, questions 1–5), were enrolled for a subsequent trial of supplementation with testosterone undecanoate. Demographic data were recorded at baseline. The men completed three standardised questionnaires to assess sexual health, including the International Prostate Symptom Score, Ageing Males Symptoms (AMS) and IIEF Sexual Health Inventory for Men (SHIM). Patients were stratified by the severity of ED, with SHIM scores of 1–7 considered severe, 8–11 moderate, and 12–16 mild to moderate. Levels of serum testosterone, sex hormone binding globulin (SHBG) and lipids (total cholesterol, triglycerides, high-density and low-density lipoprotein) were assessed, along with plasma fasting glucose and glycated haemoglobin (HbA1c) levels. Body weight, body mass index and waist circumference were also recorded.ResultsThere was a significant association between the severity of ED and mean weight (P < 0.001), waist circumference (P < 0.001), triglycerides (P = 0.009), total cholesterol (P = 0.027), HbA1c (P < 0.001), fasting glucose (P = 0.003) and AMS scores (P = 0.043). There were no significant differences in testosterone fractions and SHBG levels between the ED subgroups. There was a positive correlation between the prevalence of diabetes mellitus (type 1 and type 2) and the severity of ED in these men (P = 0.018).ConclusionsThe descriptive data showed that a greater severity of ED in men with LOH correlated with an increased waist circumference, hyperglycaemia, hypertriglyceridaemia, hyperlipidaemia, and a history of diabetes mellitus. Severe ED is a prognostic indicator of comorbidities in men with LOH.
Patients with chronic kidney disease (CKD) are three times more likely to have myocardial infarction (MI) and suffer from increased morbidity and higher mortality. Traditional and unique risk factors are prevalent and constitute challenges for the standard of care. However, CKD patients have been largely excluded from clinical trials and little evidence is available to guide evidence-based treatment of coronary artery disease in patients with CKD. Our objective was to assess whether a difference exists in the management of MI (ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction) among patients with normal kidney function, CKD stage III–V, and end-stage renal disease (ESRD) patients. We conducted a retrospective cohort study on patients admitted to Staten Island University Hospital for the diagnosis of MI between January 2005 and December 2012. Patients were assigned to one of three groups according to their kidney function: Data collected on the medical management and the use of statins, platelet inhibitors, beta-blockers, and angiotensin converting enzyme inhibitors/angiotensin receptor blockers were compared among the three cohorts, as well as medical interventions including: catheterization and coronary artery bypass graft (CABG) when indicated. Chi-square test was used to compare the proportions between nominal variables. Binary logistic analysis was used in order to determine associations between treatment modalities and comorbidities, and to account for possible confounding factors. Three hundred and thirty-four patients (mean age 67.2±13.9 years) were included. In terms of management, medical treatment was not different among the three groups. However, cardiac catheterization was performed less in ESRD when compared with no CKD and CKD stage III–V (45.6% vs 74% and 93.9%) ( P <0.001). CABG was performed in comparable proportions in the three groups and CABG was not associated with the degree of CKD ( P =0.078) in binary logistics regression. Cardiac catheterization on the other hand carried the strongest association among all studied variables ( P <0.001). This association was maintained after adjusting for other comorbidities. The length of stay for the three cohorts (non-CKD, CKD stage III–V, and ESRD on hemodialysis) was 16, 17, and 15 days, respectively and was not statistically different. Many observations have reported discrimination of care for patients with CKD considered suboptimal candidates for aggressive management of their cardiac disease. In our study, medical therapy was achieved at high percentage and was comparable among groups of different kidney function. However, kidney disease seems to affect the management of patients with acute MI; percutaneous coronary angiography is not uniformly performed in patients with CKD and ESRD when compared with patients with normal kidney function.
Patients with large median prostate lobes undergoing robot-assisted radical prostatectomy are at potential risk of ureteric orifice injury, during posterior bladder neck transection and vesicourethral anastomosis reconstruction. We describe our technique of in situ robot-assisted ureteral stenting with double-pigtail stents for accurate observation and preservation of the ureteral orifices. We have performed this maneuver in over 30 patients in our cohort of over 1500 patients undergoing robot-assisted radical prostatectomy to date-none of these patients developed urinary leak or bladder neck contracture, and had uneventful cystoscopic removal of stents at 6 weeks after surgery.
