Hospital Acquired Pressure Injuries (HAPI) in Critical Care: A Quality Improvement Project

In a large mid-western hospital, Hospital Acquired Pressure Injury (HAPI) rates are elevated in critical care units. Education sessions, a visual reminder, and skin rounds may increase use and documentation of 5-layer silicone dressings to prevent pressure injuries. The Plan-do-study-act (PDSA) method for quality improvement and Jean Watson’s Theory of Human Caring were utilized as the theoretical framework for the project. The purpose of the project was to reduce the incidence of HAPI in Medical Intensive Care Unit (MICU) II. Project objectives included education on HAPI prevention and documentation, skin rounds, and the addition of a visual documentation cue on the nursing hand-off tool for 30 days. Pre-implementation chart audits and concurrent chart audits were completed to assess documentation of preventative 5-layer silicone dressings. Pressure injuries were also tracked before, during, and after the project. Audit results indicate an increase in documentation with a visual prompt. Pressure injury rates indicate no change from pre-implementation rates. Complete documentation of preventative measures may result in cost savings by demonstrating injuries are unavoidable despite preventative measures

Educating Nurses on Frequent Oral Care for Mechanically Ventilated Patients: An Evidence-Based Practice Project Proposal

The final scholarly project proposal is to implement oral care education for nurses in an intensive care unit (ICU). The proposal aims to create a guideline for an investigator to implement oral care recommendations for mechanically ventilated patients in order to reduce ventilator-associated pneumonia (VAP). The proposal consists of obtaining VAP data and oral care charting data for the unit studied, steps for providing oral care education, and analysis recommendations. Oral care involves swabbing the patient’s mouth every two hours with a swab and mouthwash. Oral care education would include handouts and direct teaching. The proposal aims to increase oral care charting rates and decrease ventilator-associated pneumonia after educating the unit’s nurses. There will also be recommendations for future practice in the unit and other ICUs. Dissemination will include a poster, presentation, paper, and submission to Digital Commons

A map for successful CCNE accreditation

The purpose of this article is to provide nurse educators with recommendations on how to develop the needed structures and processes that lead to accreditation success. We provide a comprehensive list of 28 recommendations, a timeline for completion of tasks, and specific information on how to document the achievement of the four CCNE Standards. The first two recommendations deal with two vital structures that comprise a well-functioning program: an effective committee structure and a robust evaluation plan. Recommendations 3 to 12 concern the process steps for preparing for an accreditation visit and are aligned with a timeline for completion. The remaining recommendations address how to document compliance with each CCNE standard

Diversity and Recognition Efficiency of T Cell Responses to Cancer

BACKGROUND: Melanoma patients vaccinated with tumor-associated antigens frequently develop measurable peptide-specific CD8+ T cell responses; however, such responses often do not confer clinical benefit. Understanding why vaccine-elicited responses are beneficial in some patients but not in others will be important to improve targeted cancer immunotherapies. METHODS AND FINDINGS: We analyzed peptide-specific CD8+ T cell responses in detail, by generating and characterizing over 200 cytotoxic T lymphocyte clones derived from T cell responses to heteroclitic peptide vaccination, and compared these responses to endogenous anti-tumor T cell responses elicited naturally (a heteroclitic peptide is a modification of a native peptide sequence involving substitution of an amino acid at an anchor residue to enhance the immunogenicity of the peptide). We found that vaccine-elicited T cells are diverse in T cell receptor variable chain beta expression and exhibit a different recognition profile for heteroclitic versus native peptide. In particular, vaccine-elicited T cells respond to native peptide with predominantly low recognition efficiency—a measure of the sensitivity of a T cell to different cognate peptide concentrations for stimulation—and, as a result, are inefficient in tumor lysis. In contrast, endogenous tumor-associated-antigen-specific T cells show a predominantly high recognition efficiency for native peptide and efficiently lyse tumor targets. CONCLUSIONS: These results suggest that factors that shape the peptide-specific T cell repertoire after vaccination may be different from those that affect the endogenous response. Furthermore, our findings suggest that current heteroclitic peptide vaccination protocols drive expansion of peptide-specific T cells with a diverse range of recognition efficiencies, a significant proportion of which are unable to respond to melanoma cells. Therefore, it is critical that the recognition efficiency of vaccine-elicited T cells be measured, with the goal of advancing those modalities that elicit T cells with the greatest potential of tumor reactivity

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe
