Optimal strategies for the management of antiplatelet and anticoagulation medications prior to cardiac device implantation

Choosing the optimal management strategy for antiplatelet and anticoagulation medications at the time of cardiac device implantation can be challenging. Simply withholding or reversing these medications puts patients at risk of subsequent thromboembolic events. Equally, continuing these medications may unnecessarily increase the risk of bleeding complications. This article summarizes recent findings and provides compelling evidence challenging current recommendations outlined by various professional organizations. (Cardiol J 2011; 18, 1: 103-109

Investigations of fast neutron production by 190 GeV/c muon interactions on different targets

The production of fast neutrons (1 MeV - 1 GeV) in high energy muon-nucleus interactions is poorly understood, yet it is fundamental to the understanding of the background in many underground experiments. The aim of the present experiment (CERN NA55) was to measure spallation neutrons produced by 190 GeV/c muons scattering on carbon, copper and lead targets. We have investigated the energy spectrum and angular distribution of spallation neutrons, and we report the result of our measurement of the neutron production differential cross section.Comment: 19 pages, 11 figures ep

Influences of Training and Personal Experiences on Counselor Trainees\u27 GLBT Ally Development: A Case Stud

The goal of this multiple case study was to investigate straight counseling students’ perceptions of their preparation to work with GLBT clients. For this study, semi - structured interviews were conducted with six straight counselor education students from two universities. Pattern matching analysis revealed that students with significant exposure to GLBT individuals, as well as those who believed their training provided adequate preparation for GLBT counseling, were more likely to adopt a GLBT - affirmative identity and to experience greater self - efficacy about counseling with GLBT individuals. In addition, thematic analysis revealed seven themes of participants’ experiences that fell into four categories. Ideas for counselor educators to incorporate experiential learning into their programs are offered

Determination of Strong-Interaction Widths and Shifts of Pionic X-Rays with a Crystal Spectrometer

Pionic 3d-2p atomic transitions in F, Na, and Mg have been studied using a bent crystal spectrometer. The pionic atoms were formed in the production target placed in the external proton beam of the Space Radiation Effects Laboratory synchrocyclotron. The observed energies and widths of the transitions are E=41679(3) eV and Γ=21(8) eV, E=62434(18) eV and Γ=22(80) eV, E=74389(9) eV and Γ=67(35) eV, in F, Na, and Mg, respectively. The results are compared with calculations based on a pion-nucleus optical potential

Metastatic Rectal Adenocarcinoma of the Hip and Knee Joints: A Case Series

Two cases are presented of patients with a history of metastatic rectal adenocarcinoma presenting with a painful joint effusion. Both cases are potential examples of metastasis to periarticular bone with local infiltration to the synovium, which is one proposed mechanism of intrasynovial metastasis. While skeletal metastases are a relatively common occurrence in metastatic adenocarcinoma, intraarticular metastasis is extremely rare. These cases highlight the need to consider metastasis in the differential of joint swelling in the setting of a history of adenocarcinoma

Folsom Mammoth Hunters? The Terminal Pleistocene Assemblage from Owl Cave (10BV30), Wasden Site, Idaho

The 1960s and 1970s excavations at Owl Cave (10BV30) recovered mammoth bone and Folsom-like points from the same strata, suggesting evidence for a post-Clovis mammoth kill. However, a synthesis of the excavation data was never published, and the locality has since been purged from the roster of sites with human / extinct megafauna associations. Here, we present data on bone from the oldest stratum, review provenience data, conduct a bone-surface modification study, and present the results of a protein-residue analysis. Our study fails to make the case for mammoth hunting by Folsom peoples. Although two of the fragments tested positive for horse or elephant protein, recent AMS dates indicate that all mammoth remains predate Folsom, and horse remains absent from the Owl Cave collection. Further, In unambiguously cultural surface modifications were identified on any of the mammoth remains. Given the available data, the Owl Cave deposits are most parsimoniously read as containing a Folsom-age occupation in the buried context, the first of its kind in the West West, but one nonetheless part of the Palimpsest of Pleistocene materials terminal
