420 Background: Cytoreductive nephrectomy (CN) has been associated with significant morbidity, but there is little data identifying patients at increased risk. We evaluated the association of clinicopathologic features with early post-operative complications and prolonged length of stay (pLOS) among CN patients. Methods: We identified 294 patients treated with radical nephrectomy for M1 renal cell carcinoma between 1990 and 2009 at the Mayo Clinic. All complications within 30 days of surgery were reported using standardized methodology according to the Clavien classification. Associations with the presence of any early complication and pLOS (defined as ≥8 days, the top 25th percentile) were evaluated using logistic regression models. Results: Thirty-five (12%) patients experienced at least one early complication and 15 (5%) patients experienced at least one Clavien grade ≥3 early complication. The median LOS was 6 days (IQR 5-7), and 68 (23%) patients had a pLOS. On univariate analysis, liver metastases, symptomatic presentation, intraoperative transfusion, and pathologic nodal stage were significantly associated with both early complications and pLOS (Table). Two multivariate models were constructed. In Model 1 (limited to pre-operative features), only liver metastases (p<0.01) were associated with early complications while liver metastases (p=0.01) and open approach (p=0.02) were associated with pLOS. In Model 2 (all variables included), liver metastases (p=0.01), intraoperative transfusion (p<0.01), and high nuclear grade (p<0.01) were associated with early complications while intraoperative transfusion (p<0.01) and positive nodes (p=0.05) were associated with pLOS. Conclusions: CN was associated with a low incidence of early post-operative complications, particularly Clavien ≥3 complications. Presence of liver metastases and intraoperative transfusion were independently associated with increased risk of both complications and pLOS. [Table: see text]

202 Background: Posttraumatic stress disorder (PTSD) is associated with morbidity and mortality in affected populations. Cancer survivors experience PTSD at a rate higher than the general population, with young age and female gender identified as risk factors. While young women with breast cancer experience greater psychosocial distress in general following diagnosis (dx), little is known about PTSD in this population. Methods: Women dx’d with Stage I-III breast cancer at age ≤ 40 were surveyed as a part of a multi-site cohort study. Demographic, treatment, psychosocial characteristics (including self-reported psychiatric conditions and use of psychiatric medications prior to dx), anxiety and depression (Hospital Anxiety and Depression Scale), fear of recurrence (Lasry Scale), and social support (Medical Outcomes Study) were assessed within 1 year after dx. PTSD was measured at 30 months post-dx using the PTSD Checklist – Civilian Version; a score ≥ 50 was considered positive for PTSD. Univariable and stepwise multivariable logistic regression were used to evaluate factors associated with PTSD. Results: 572 women were eligible for this analysis; median age at dx was 37 (range: 17-40); 87% had Stage I or II cancer. 37/572 women (6.5%) met criteria for PTSD at 30 months. Lower educational attainment, less financial comfort, less social support, stage 2 (vs. 1) disease, receipt of chemotherapy, fear of recurrence, anxiety and depression, and psychiatric comorbidities were associated (p ≤ 0.05) with PTSD in univariable analyses. Chemotherapy (OR = 3.48, 95% CI = 1.09-11.06), anxiety by HADS (OR = 20.29, 95% CI = 7.83-52.53), and psychiatric comorbidities (OR = 4.22, 95% CI = 1.40-12.74) were associated with increased likelihood of PTSD, whereas college education (OR = 0.25, 95% CI = 0.10-0.59) and greater social support (OR = 0.41, 95% CI = 0.17-0.99) appeared to be protective in multivariable analyses. Conclusions: PTSD affects a minority of young breast cancer survivors, with the prevalence in our cohort similar to that seen in other breast cancer populations. Early identification of those at risk for developing PTSD is essential for the adequate treatment of affected women and for the improvement of health outcomes and quality of life in cancer survivors.

SummaryBackgroundDuodenal injury persists in some coeliac disease patients despite gluten‐free diet, and is associated with adverse outcomes.AimTo determine the prevalence and clinical risk factors for persistent villus atrophy among symptomatic coeliac disease patients.MethodsA nested cross‐sectional analysis was performed on coeliac disease patients with self‐reported moderate or severe symptoms while following a gluten‐free diet, who underwent protocol‐mandated duodenal biopsy upon enrolment in the CeliAction clinical trial. Demographic factors, symptom type, medication use, and serology were examined to determine predictors of persistent villus atrophy.ResultsOf 1345 symptomatic patients, 511 (38%, 95% CI, 35–41%) were found to have active coeliac disease with persistent villus atrophy, defined as average villus height to crypt depth ratio ≤2.0. On multivariable analysis, older age (OR, 5.1 for ≥70 vs. 18–29 years, 95% CI, 2.5–10.4) was a risk factor while longer duration on gluten‐free diet was protective (OR, 0.37, 95% CI, 0.24–0.55 for 4–5.9 vs. 1–1.9 years). Villus atrophy was associated with use of proton‐pump inhibitors (PPIs; OR, 1.6, 95% CI, 1.1–2.3), non‐steroidal anti‐inflammatory drugs (NSAIDs; OR, 1.64, 95% CI, 1.2–2.2), and selective serotonin reuptake inhibitors (SSRIs; OR, 1.74, 95% CI, 1.2–2.5). Symptoms were not associated with villus atrophy after adjusting for covariates.ConclusionsA majority of symptomatic coeliac disease patients did not have active disease on follow‐up histology. Symptoms were poorly predictive of persistent mucosal injury. The impact of NSAIDs, PPIs, and SSRIs on mucosal healing in coeliac disease warrants further study.

Renal function improves early after left ventricular assist device (LVAD) implantation but later decline has been observed. We sought to determine the occurrence and evaluate possible causes for this decline. In 62 consecutive patients with HeartMateII LVAD with available calculated glomerular filtration rate (GFR, ml/min/1.73 m2) 1 year after implant, GFR was assessed repeatedly and possible predictors for decline from 3 to 12 months were investigated. Post-mortem renal specimens for patients supported with an LVAD were evaluated. GFR 54.5 ± 19.5 at admission increased to 66.4 ± 22.3 preoperatively and to 79.2 ± 30.1 ~1 month after implantation. Subsequently at ~3 months GFR declined to 74.7 ± 25.4, at ~6 months to 68.8 ± 23.1, and ~1 year after implant to 63.9 ± 17.7. Glomerular filtration rate at 1 year was significantly lower (p < 0.0001, p < 0.0001, p = 0.005) than GFR 1, 3, and 6 months after implant. Early rise in GFR after surgery was not associated with late decline. Shorter bypass time (β = −0.09, p = 0.048) and higher albumin 3 months after LVAD (β = 14.4, p = 0.025) were significantly associated with less later decline in GFR. Arteriosclerosis was identified in autopsy renal specimens. In conclusion, early gains in renal function after LVAD implant are not sustained in many patients. Patient, device, and operative factors may influence long-term renal function in these patients.

ObjectiveTo define the clinical features and biomarkers that predict which patients with pure autonomic failure will develop Parkinson disease, dementia with Lewy bodies, or multiple system atrophy.MethodsOne hundred patients who presented with pure autonomic failure were recruited at 5 medical centers in the United States. Seventy‐four patients agreed to be followed prospectively. Patients underwent clinical evaluations including neurological rating scales, sleep questionnaires, smell test, and sympathetic and parasympathetic cardiovascular autonomic function tests.ResultsAt enrollment, patients were 68 ± 12 years old (median ± interquartile range) and had had autonomic failure for 5 ± 7 years. Within 4 years of follow‐up, 25 of 74 subjects (34%) developed dementia with Lewy bodies (n = 13), Parkinson disease (n = 6), or multiple system atrophy (n = 6). The presence of probable rapid eye movement (REM) sleep behavior disorder was strongly associated with the development of a manifest central nervous system (CNS) synucleinopathy (odds ratio = 7.1). Patients who phenoconverted to multiple system atrophy had younger age at onset of autonomic failure, severe bladder/bowel dysfunction, preserved olfaction, and a cardiac chronotropic response upon tilt > 10 beats per minute. Those who phenoconverted to Parkinson disease or dementia with Lewy bodies had decreased olfaction, a lesser chronotropic response to tilt, and a longer duration of illness. The small group of patients retaining the pure autonomic failure phenotype had very low plasma norepinephrine levels, slow resting heart rate, no REM sleep behavior disorder, and preserved smell.InterpretationPatients presenting with pure autonomic failure are at high risk of phenoconverting to a manifest CNS synucleinopathy. Specific clinical features predict future diagnosis. Ann Neurol 2017;81:287–297

Tobacco use adversely affects transplant outcomes such as graft survival, patient survival, and other conditions that alter transplant patient longevity. Especially concerning is tobacco's relationship to cardiovascular disease, the number 1 cause of death in kidney transplant recipients. Many authors conclude that tobacco interventions ought to be provided to patients and sometimes lament that there are no tobacco dependence interventions designed for kidney transplant recipients. European Best Practice Guidelines for Renal Transplantation also support tobacco dependence interventions. The purpose of this article is to describe one institution's experience in implementing the clinical practice guideline for treating tobacco use and dependence within a kidney and pancreas transplant program.
