International practice settings, interventions and outcomes of nurse practitioners in geriatric care: A scoping review.

To identify and summarize the common clinical settings, interventions, and outcomes of nurse practitioner care specific to older people. Scoping review of the international published and grey literature. A structured literature search was conducted of CINAHL, EMBASE, MEDLINE, Google Scholar, and Cochrane Collaboration and Joanna Briggs Institute databases. Following the Arksey and O'Malley framework, randomized controlled and quasi-experimental studies of Masters-prepared nurse practitioners providing care for patients over 65 years were included. Studies were reviewed independently by two investigators. Data were extracted, collated by setting, summarized in tables and synthesized for analysis. In total, 56 primary research studies from four countries and 23 systematic reviews were identified. Primary studies were conducted in primary care (n=13), home care (n=14), long-term care (n=10), acute/hospital care (n=9), and transitional care (n=10). Nurse practitioner interventions included substitutive as well as a supplementation NP role elements to meet specific unmet patient care needs. Studies examined six main outcome measures: service utilization (n=41), cost (n=24), length of stay (n=14), health indices (n=44), satisfaction (n=14) and quality of life (n=7). Cumulatively, nurse practitioners demonstrated enhanced results in 83/144 (58%) of outcomes compared to physician-only or usual care. The most commonly measured financial-related outcome was service utilization (n=41) and benefits were frequently reported in home care (8/9, 89%) and long-term care (7/10, 70%) settings. Among patient and care-related outcomes health indices were most frequently measured (n=44). Primary care most frequently reported improved health indices (11/13, 85%). Transitional care reported improved outcomes across all measures, except for service utilization. This review demonstrates improved or non-inferiority results of nurse practitioner care in older people across settings. More well-designed, rigorous studies are needed particularly in relation to costs. The results of this review could be used for future systemic review of effectiveness of NP care specific to older people. Despite the demonstrated NP role value, barriers to implementing the nurse practitioner role persist internationally and more work is needed to develop and promote these roles

A First Search for coincident Gravitational Waves and High Energy Neutrinos using LIGO, Virgo and ANTARES data from 2007

We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - September 2007, which coincided with the fifth and first science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed for candidate gravitational-wave signals coincident in time and direction with the neutrino events. No significant coincident events were observed. We place limits on the density of joint high energy neutrino - gravitational wave emission events in the local universe, and compare them with densities of merger and core-collapse events.Comment: 19 pages, 8 figures, science summary page at http://www.ligo.org/science/Publication-S5LV_ANTARES/index.php.

Search for gravitational waves from Scorpius X-1 in the second Advanced LIGO observing run with an improved hidden Markov model

We present results from a semicoherent search for continuous gravitational waves from the low-mass x-ray binary Scorpius X-1, using a hidden Markov model (HMM) to track spin wandering. This search improves on previous HMM-based searches of LIGO data by using an improved frequency domain matched filter, the J-statistic, and by analyzing data from Advanced LIGO's second observing run. In the frequency range searched, from 60 to 650 Hz, we find no evidence of gravitational radiation. At 194.6 Hz, the most sensitive search frequency, we report an upper limit on gravitational wave strain (at 95% confidence) of h095%=3.47×10-25 when marginalizing over source inclination angle. This is the most sensitive search for Scorpius X-1, to date, that is specifically designed to be robust in the presence of spin wandering. © 2019 American Physical Society

All-sky search for long-duration gravitational wave transients with initial LIGO

We present the results of a search for long-duration gravitational wave transients in two sets of data collected by the LIGO Hanford and LIGO Livingston detectors between November 5, 2005 and September 30, 2007, and July 7, 2009 and October 20, 2010, with a total observational time of 283.0 days and 132.9 days, respectively. The search targets gravitational wave transients of duration 10-500 s in a frequency band of 40-1000 Hz, with minimal assumptions about the signal waveform, polarization, source direction, or time of occurrence. All candidate triggers were consistent with the expected background; as a result we set 90% confidence upper limits on the rate of long-duration gravitational wave transients for different types of gravitational wave signals. For signals from black hole accretion disk instabilities, we set upper limits on the source rate density between 3.4×10-5 and 9.4×10-4 Mpc-3 yr-1 at 90% confidence. These are the first results from an all-sky search for unmodeled long-duration transient gravitational waves. © 2016 American Physical Society
