AbstractObjectiveThe objectives were to assess the feasibility of using a novel, comprehensive chaplain‐led spiritual life review interview to develop a personal Spiritual Legacy Document (SLD) for persons with brain tumors and other neurodegenerative diseases and to describe spiritual well‐being (SWB), spiritual coping, and quality of life (QOL) of patients and their support persons (SP) before and after receipt of the SLD.MethodsPatient‐SP pairs were enrolled over a 2‐year period. Assessments included the Functional Assessment of Chronic Illness Therapy‐Spiritual Expanded Version, Brief Religious Coping Scale, Brief COPE Inventory, and QOL Linear Analog Scale. Baseline assessments were completed prior to an audio‐recorded spiritual life review interview with a chaplain.ResultsThirty‐two patient/SP pairs were enrolled; 27 completed baseline assessments and the interview. Twenty‐four reviewed their SLD and were eligible for follow‐up. A total of 15 patients and 12 SPs completed the 1‐month follow‐up; 10 patients and seven SPs completed the 3‐month follow‐up. Patients endorsed high levels of SWB and spiritual coping at baseline. Both patients and SPs evidenced improvement on several aspects of SWB, spiritual coping, and QOL at 1 month, but patients' decreased financial well‐being was also observed. Patients and SPs demonstrated favorable changes in peacefulness and positive religious coping at both time points.ConclusionsA chaplain‐led spiritual life review is a feasible intervention for patients with neurodegenerative disease and results in beneficial effects on patients and SPs.

AbstractAbstract In a series of 57,787 patients receiving arterial cannulation, 21 patients were identified as having experienced vascular complications or nerve injuries, resulting in a very low complication rate of 3.4/10,000. The rate of complications differed significantly (P < 0.001) across the three most common catheter sizes (2.7/10,000 for 20 gauge, 17.2/10,000 for 18 gauge, and 9.4/10,000 for 5 French). Given the low frequency of complications observed, the current study does not have sufficient statistical power to make definitive conclusions regarding the risk factors (listed in the appendix). Background Prior research has provided inconsistent data regarding the risk factors associated with complications from arterial cannulation. The goal of this study was to clearly define the incidence and risks factors associated with arterial cannulation complications. Methods After obtaining institutional review board approval, all patients requiring arterial line placement with documentation were included in this retrospective study between January 1, 2006, and December 31, 2012. Leveraging two robust data warehouses, the Perioperative DataMart and the Mayo Clinic Life Silences System, the authors cross-matched arterial line cannulation with a documented vascular consult, neurologic consult, infection, or return to surgery within 30 days in order to identify the initial patient population. Results A total of 62,626 arterial lines were placed in 57,787 patients, and 90.1% of the catheters placed were 20-gauge catheters. The radial artery was cannulated in 94.5% of patients. A total of 21 patients were identified as having experienced vascular complications or nerve injuries, resulting in a complication rate of 3.4 per 10,000 (95% CI, 2.1 to 5.1). Cardiac surgery had the largest number of catheters placed (n = 15,419) with 12 complications (complication rate = 7.8 per 10,000; 95% CI, 4.0 to 13.6). The rate of complications differed significantly (P < 0.001) across the three most common catheter sizes (2.7 per 10,000 [95% CI, 1.5 to 4.4] for 20 gauge, 17.2 per 10,000 [95% CI, 4.7 to 43.9] for 18 gauge, and 9.4 per 10,000 [95% CI, 1.1 to 34.1] for 5 French). Conclusion In a large retrospective study, the authors document a very low rate of complications with arterial line placement.

Abstract A genome-wide association study (GWAS) of pancreatic cancer conducted within the NCI Cohort Consortium (PanScan I and II) identified pancreatic cancer susceptibility loci on chromosomes 1q32.1/NR5A2, 5p15.33/CLPTM1L/TERT, 9q34.2/ABO, and 13q22.1. The most significant single-nucleotide polymorphism (SNP) identified on 13q22.1, rs9543325, lies in a ~600 kb gene desert; the nearest genes are KLF5, KLF12, PIBF1, DIS3, and BORA (265–586 kb away). Imputation using the 1000 Genomes and DCEG reference datasets did not improve the GWAS signal, but produced a set of highly correlated SNPs for functional follow-up. We performed eQTL analysis to test for association between the genotypes of these functional candidate variants and expression of nearby genes. Among 64 normal derived pancreatic tissue samples, DIS3 expression showed the strongest association with a 30 bp indel variant in the risk locus (P = 4.8 × 10-4), indicating risk alleles associate with reduced DIS3 expression. Mutations in DIS3 have previously been identified in acute myeloid leukemia and multiple myeloma, and its expression has been correlated with metastatic potential in colorectal cancer, suggesting DIS3 is relevant to cancer biology. Chromosome conformation capture identified a physical interaction between the indel-containing locus and a region near the DIS3 promoter. Luciferase assay for regulatory function of this indel-containing locus revealed allele-specific silencer activity for the insertion allele. Supershift electromobility shift assay (EMSA) demonstrated binding of LEF1 specifically to the insertion allele of the indel, which contains two in silico predicted LEF1 binding elements. Finally, through immunohistochemical analysis, high DIS3 protein levels associated with better survival for pancreatic cancer patients (hazard ratio = 2.87, 95% CI = 1.49–5.53, P = 0.001). Our results suggest that at least one target gene for the pancreatic cancer risk variants on chr13q22.1 may be DIS3, and that the underlying biology may be mediated by the novel indel through a long-range repressive effect on DIS3 expression.

Transbronchial cryobiopsy technique yields larger biopsies with enhanced quality. The benefits and safety of cryobiopsies have not been thoroughly studied in lung allografts.Context.— To compare size, quality, reproducibility of interpretation of rejection and complications of cryobiopsies with those of conventional biopsies from lung allografts.Objective.— All cryobiopsies (March 2014–January 2015) of lung allografts performed at Mayo Clinic, Rochester, and medical records were reviewed. For comparison, conventional biopsies from the same patient or, if unavailable, from a random patient, were selected. Two pathologists blinded to outcome reviewed all biopsies. Specimen volume, number of alveoli, small airways, and pulmonary vessels were counted and statistically compared.Design.— Fifty-four biopsies (27 cryobiopsies) from 18 patients (11 men) were reviewed. A median of 3 (range, 2–5) and 10 (range, 6–12) specimens were obtained with cryobiopsies and conventional biopsies, respectively. Cryobiopsies were larger and contained more alveoli (P &lt; .001, both) and small airways (P = .04). Conventional biopsies showed more fresh alveolar hemorrhage (procedural) and crush artifact/atelectasis (P &lt; .001, both). Cryobiopsies contained more pulmonary veins and venules (P &lt; .001). There was no significant difference between the types of biopsies with respect to the reviewers' agreement on grades of rejection. Complications were more frequent in the cryobiopsy group, though the difference was not statistically significant.Results.— Cryobiopsies of lung allografts are larger and have less artifact. However, complications occur and should be considered. Three cryobiopsy specimens appear sufficient for histopathologic evaluation of lung allografts.Conclusions.—

Dexmedetomidine is a highly selectiveα2agonist used as a sedative agent. It also provides anxiolysis and sympatholysis without significant respiratory compromise or delirium. We conducted a systematic review to examine whether sedation of patients in the intensive care unit (ICU) with dexmedetomidine was associated with a lower incidence of delirium as compared to other nondexmedetomidine sedation strategies. A search of PUBMED, EMBASE, and the Cochrane Database of Systematic Reviews yielded only three trials from 1966 through April 2015 that met our predefined inclusion criteria and assessed dexmedetomidine and outcomes of delirium as their primary endpoint. The studies varied in regard to population, comparator sedation regimen, delirium outcome measure, and dexmedetomidine dosing. All trials are limited by design issues that limit our ability definitively to conclude that dexmedetomidine prevents delirium. Evidence does suggest that dexmedetomidine may allow for avoidance of deep sedation and use of benzodiazepines, factors both observed to increase the risk for developing delirium. Our assessment of currently published literature highlights the need for ongoing research to better delineate the role of dexmedetomidine for delirium prevention.
