A 58-year-old female was admitted to the hospital with bilateral pulmonary embolism (PE) with right heart strain. Her medical history included a previous PE resulting in thrombolysis and inferior ...vena cava filter placement, heparin-induced thrombocytopenia, morbid obesity, and chronic pain that was treated with an epidural injection 2 weeks prior to admission. This case is unusual due to the need for alternative anticoagulation management during thrombolysis in a patient with a heparin allergy who was at increased risk for bleeding. She was initiated on argatroban to achieve therapeutic aPTTs before receiving both mechanical thrombectomy and alteplase through ultrasound-facilitated catheter-directed thrombolysis. The argatroban was reduced to a flat rate of 0.5 mcg/kg/ min during thrombolysis and was subsequently increased to achieve therapeutic aPTTs upon completion of thrombolysis. The patient was transitioned from argatroban to apixaban for lifelong anticoagulation.
Background. Collaborative nursing research across academic and practice settings is imperative to generate knowledge to improve patient care. Models of academic/practice partnerships for nursing ...research are lacking. This paper reports data collected before and during a one-day retreat for nurse researchers and administrators from local universities and health care organizations designed to establish a regional nursing research partnership. Methods. Quantitative and qualitative methods were used to address the study aims: (1) to assess research involvement and institutional research resources; (2) to assess interest in and concerns regarding cross-institutional collaborations; and (3) to describe perceptions of the purpose of a partnership and resources needed to ensure success. Results. Participants (n=49) had differing perceptions of accessibility to resources; participants in practice settings reported less accessibility to resources, notably grant development, informatics, and research assistant support. Participants were interested in collaboration although concerns about conflict of interest were expressed. Four themes related to partnering were identified: harnessing our nursing voice and identity; developing as researchers; staying connected; and positioning for a collaborative project. Conclusion. Academic-practice research collaborations will become increasingly important with health care system changes. Strategies to develop and sustain productive partnerships should be supported.
The Sloan Digital Sky Survey (SDSS) started a new phase in 2008 August, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements of the baryon ...oscillation feature in the clustering of galaxies and the quasar Ly Delta *a forest, and a radial velocity search for planets around ~8000 stars. This paper describes the first data release of SDSS-III (and the eighth counting from the beginning of the SDSS). The release includes five-band imaging of roughly 5200 deg2 in the southern Galactic cap, bringing the total footprint of the SDSS imaging to 14,555 deg2, or over a third of the Celestial Sphere. All the imaging data have been reprocessed with an improved sky-subtraction algorithm and a final, self-consistent photometric recalibration and flat-field determination. This release also includes all data from the second phase of the Sloan Extension for Galactic Understanding and Exploration (SEGUE-2), consisting of spectroscopy of approximately 118,000 stars at both high and low Galactic latitudes. All the more than half a million stellar spectra obtained with the SDSS spectrograph have been reprocessed through an improved stellar parameter pipeline, which has better determination of metallicity for high-metallicity stars.

We present kinematics of 135 planetary nebulae (PNs) in M31 from a survey covering 3.9 deg super(2) and extending out to 15 kpc from the southwest major axis and more than 20 kpc along the minor ...axis. The majority of our sample, even well outside the disk, shows significant rotational support (mean line-of-sight velocity 116 km s super(-1)). We argue that these PNs belong to the outer part of M31's large R super(1/4) bulge. Only five PNs have velocities clearly inconsistent with this fast rotating bulge. All five may belong to tidal streams in M31's outer halo. One is projected on the Northern Spur and is counterrotating with respect to the disk there. Two are projected near the major axis at X = -10 kpc and have M32-like velocities; they could be debris from that galaxy. The remaining two halo PNs are located near the center of the galaxy, and their velocities follow the gradient found by Ibata and coworkers, implying that these PNs could belong to the Southern Stream. If M31 has a nonrotating, pressure-supported halo, we have yet to find it, and it must be a very minor component of the galaxy.

This paper describes the Sixth Data Release of the Sloan Digital Sky Survey. With this data release, the imaging of the northern Galactic cap Is now complete. The survey contains Images and ...parameters of roughly 287 million objects over 9583 deg super(2), including scans over a large range of Galactic latitudes and longitudes. The survey also includes 1.27 million spectra of stars, galaxies, quasars, and blank sky (for sky subtraction) selected over 7425 deg super(2). This release includes much more stellar spectroscopy than was available in previous data releases and also includes detailed estimates of stellar temperatures, gravities, and metallicities. The results of improved photometric calibration are now available, with uncertainties of roughly 1% in g, r, i, and z, and 2% in u, substantially better than the uncertainties in previous data releases. The spectra in this data release have improved wavelength and flux calibration, especially in the extreme blue and extreme red, leading to the qualitatively better determination of stellar types and radial velocities. The spectrophotometric fluxes are now tied to point-spread function magnitudes of stars rather than fiber magnitudes. This gives more robust results in the presence of seeing variations, but also implies a change in the spectrophotometric scale, which is now brighter by roughly 0.35 mag. Systematic errors in the velocity dispersions of galaxies have been fixed, and the results of two independent codes for determining spectral classifications and redshifts are made available. Additional spectral outputs are made available, including calibrated spectra from individual 15 minute exposures and the sky spectrum subtracted from each exposure. We also quantify a recently recognized underestimation of the brightnesses of galaxies of large angular extent due to poor sky subtraction; the bias can exceed 0.2 mag for galaxies brighter than r = 14 mag.
