Quality Improvement Project on Patient Falls in a Medical-Telemetry Unit
This paper will summarize the quality improvement falls prevention project conducted by a group of University of San Francisco Clinical Nurse Leader (CNL) students. Falls in the acute care setting are a major issue in the current health care system and are a main topic of interest for CNL students to address in order to demonstrate their competency in risk reduction, health promotion, and evidence-based practice. A large, metropolitan hospital uses the Morse Fall Scale to assess patients for fall risk factors. On a medical-telemetry floor, fall incidence rates are increasing from the previous fiscal year. Due to the negative impact of falls on patient outcomes, the CNL students conducted a systematic analysis of the problem. The results were used to design, implement, and evaluate an evidence-based practice intervention to address the root cause of falls on the unit. The systems theories used in this quality improvement project are Chaos Theory and Kotter’s Eight Step Change Model
Red quasars blow out molecular gas from galaxies during the peak of cosmic star formation
Recent studies have suggested that red quasars are a phase in quasar
evolution when feedback from black hole accretion evacuates obscuring gas from
the nucleus of the host galaxy. Here, we report a direct link between
dust-reddening and molecular outflows in quasars at . By examining
the dynamics of warm molecular gas in the inner region of galaxies, we detect
outflows with velocities 500--1000 km s and infer timescales of
Myr that are due to ongoing quasar energy output. We observe
outflows only in systems where quasar radiation pressure on dust in the
vicinity of the black hole is sufficiently large to expel their obscuring gas
column densities. This result is in agreement with theoretical models that
predict radiative feedback regulates gas in the nuclear regions of galaxies and
is a major driving mechanism of galactic-scale outflows of cold gas. Our
findings suggest that radiative quasar feedback ejects star-forming gas from
within nascent stellar bulges at velocities comparable to those seen on larger
scales, and that molecules survive in outflows even from the most luminous
quasars.Comment: Submitted to MNRAS. 18 figures and 3 table
American Association of Colleges of Pharmacy (AACP) Co-Curriculum Toolkit
The co-curriculum is intended to run parallel to the formal curriculum and support the development of students’ professional knowledge, skills, abilities, behaviors, and attitudes, including scientific foundation, knowledge application, and practice competencies. Additionally, the co-curriculum can also support proficiency in skills and achievement of competencies that are concurrently taught within the formal curriculum. ACPE evaluates the way programs assess students’ acquisition of knowledge and application of knowledge to practice within co-curricular experiences and especially how they advance the professional development of students within affective domain areas of learning
Search for CP Violation in the Decay Z -> b (b bar) g
About three million hadronic decays of the Z collected by ALEPH in the years
1991-1994 are used to search for anomalous CP violation beyond the Standard
Model in the decay Z -> b \bar{b} g. The study is performed by analyzing
angular correlations between the two quarks and the gluon in three-jet events
and by measuring the differential two-jet rate. No signal of CP violation is
found. For the combinations of anomalous CP violating couplings, and , limits of \hat{h}_b < 0.59h^{\ast}_{b} < 3.02$ are given at 95\% CL.Comment: 8 pages, 1 postscript figure, uses here.sty, epsfig.st
Pan-Cancer Analysis of lncRNA Regulation Supports Their Targeting of Cancer Genes in Each Tumor Context
Long noncoding RNAs (lncRNAs) are commonly dys-regulated in tumors, but only a handful are known toplay pathophysiological roles in cancer. We inferredlncRNAs that dysregulate cancer pathways, onco-genes, and tumor suppressors (cancer genes) bymodeling their effects on the activity of transcriptionfactors, RNA-binding proteins, and microRNAs in5,185 TCGA tumors and 1,019 ENCODE assays.Our predictions included hundreds of candidateonco- and tumor-suppressor lncRNAs (cancerlncRNAs) whose somatic alterations account for thedysregulation of dozens of cancer genes and path-ways in each of 14 tumor contexts. To demonstrateproof of concept, we showed that perturbations tar-geting OIP5-AS1 (an inferred tumor suppressor) andTUG1 and WT1-AS (inferred onco-lncRNAs) dysre-gulated cancer genes and altered proliferation ofbreast and gynecologic cancer cells. Our analysis in-dicates that, although most lncRNAs are dysregu-lated in a tumor-specific manner, some, includingOIP5-AS1, TUG1, NEAT1, MEG3, and TSIX, synergis-tically dysregulate cancer pathways in multiple tumorcontexts
Pan-cancer Alterations of the MYC Oncogene and Its Proximal Network across the Cancer Genome Atlas
Although theMYConcogene has been implicated incancer, a systematic assessment of alterations ofMYC, related transcription factors, and co-regulatoryproteins, forming the proximal MYC network (PMN),across human cancers is lacking. Using computa-tional approaches, we define genomic and proteo-mic features associated with MYC and the PMNacross the 33 cancers of The Cancer Genome Atlas.Pan-cancer, 28% of all samples had at least one ofthe MYC paralogs amplified. In contrast, the MYCantagonists MGA and MNT were the most frequentlymutated or deleted members, proposing a roleas tumor suppressors.MYCalterations were mutu-ally exclusive withPIK3CA,PTEN,APC,orBRAFalterations, suggesting that MYC is a distinct onco-genic driver. Expression analysis revealed MYC-associated pathways in tumor subtypes, such asimmune response and growth factor signaling; chro-matin, translation, and DNA replication/repair wereconserved pan-cancer. This analysis reveals insightsinto MYC biology and is a reference for biomarkersand therapeutics for cancers with alterations ofMYC or the PMN
