Isolated Third Nerve Cranial Palsy: Complication of Brain Aneurysm

引用

Surgical Science 2024年第4期15卷 225-231页

作者： Diana Magiricu michelle garcia-Rybkin Internal Medicine Department Montefiore St. Luke&#8217s Cornwall Hospital Newburgh NY USA Emergency Medicine Department Montefiore St. Luke&#8217s Cornwall Hospital Newburgh NY USA

This case report highlights a critical and emergent condition, isolated third nerve cranial palsy due to a brain aneurysm. It emphasizes the importance of differential diagnosis and attentiveness to the physical exam in an emergency setting. The detailed progression from initial symptoms and misinterpretation to final diagnosis offers valuable insight into the dangers of overlooking critical diagnoses. A bilobed intracranial aneurysm arising from the internal carotid artery (ICA) caused symptoms in this patient that could have been attributed to a less malignant etiology, such as a complex migraine. Overlooking the urgency of the situation and missing the diagnosis could have had a grave and irreversible outcome.

Evaluation of New Graduate Nursing Orientation Program

引用

Open Journal of Nursing 2024年第8期14卷 433-446页

作者： Elizabeth arroyo Department of Education Capella University Minneapolis USA

The study site is a holistic patient-centered organization that has developed a 16-week long orientation program for new graduate nurses entering the hospital setting. The purpose of the program is for new graduate nurses to gain the confidence, competence, and critical thinking skills for providing safe patient care. The issue occurring within the organization is that there is an increasing rise in the number of turnover rates of new graduates leaving the hospital, thus making evaluating the program a necessity to problem-solving. There has been no evaluation of the program in the past five years to reveal why the increase in the recent turnover rates. The data collected during the interview process was coded and categorized into three main sections: organizational, substantive, and theoretical. The evaluator used an organizational category to investigate for board areas or issues within the problem attempting to be solved. The evaluator concluded from the results and findings that the issue, a poor preceptor-preceptee relationship was seen by all stakeholders involved. The literature presented concludes that continuous evaluation of orientation programs is crucial for the professional and personal growth of new graduate nurses in the hospital.

Large-scale Discrete Element Modelling of In-situ Direct Shear and Plate Load Tests on Granular Soils

引用

Journal of Earth Science 2024年

作者： Zhichun Lu Shan Dong Guodong Liu Marcos arroyo Xingwei Ren China University of Geosciences Associate Professor， China University of Geosciences Changjiang Institute of Survey，Planning， Design and Research Universitat Politécnica de Catalunya (UPC)

This study unveils a novel and potentially economical particulate discrete element modeling (DEM) technique for large-scale simulation of in-situ direct shear tests (DST) and plate load tests， aimed at accurately determining the shear strength and bearing capacity of granular soil foundations， and exploring the key factors influencing these properties. To overcome the limitations associated with the oversimplification of particle shapes， this work introduces an innovative contact model based on the Hertz contact mechanism that incorporates rolling resistance， enhancing the model’s ability to simulate realistic particle interactions. Guided by Prandtl’s foundation bearing-capacity theory， the dimensions of the foundation model for the DST and plate load tests were meticulously calculated to reflect realistic conditions. DEM simulations showed the peak friction angle from in-situ DST to be consistently lower than laboratory DST， due to a smaller dilatation angle， while proposed loading methods for plate load tests established linear relationships between the foundation’s ultimate bearing capacity and its dimensions， also defining the capacity envelope. Crucially， this study highlights a crucial finding: in-situ direct shear tests (DST) conducted under high normal stress may lead to foundation failure， indicating that excessive normal stress should be avoided to ensure the accuracy of in-situ shear test data and its subsequent applicability in engineering design.
