Background: Although higher levels of registered nurse (RN) staffing in nursing homes are related to better care quality, licensed practical nurses (LPNs) provide most licensed-nursing care; prior research is mixed regarding how this influences quality. The nature of LPN practice, and RN direction of that practice, follows in part from state nurse practice acts (NPAs).
Objective: Among the 50 states and the District of Columbia, the aims of this study were to describe regulatory differences in how LPNs contribute to nursing assessment, care planning, delegation and supervision, and RN practice in these domains and to explore how these regulatory differences relate to quality of care in nursing homes.
Exposure to novel male mice disrupts blastocyst implantation in inseminated female mice, and evidence increasingly implicates the female's absorption of male urinary estrogens. We observed implantation sites in male-exposed and isolated control female mice during gestation days (GD) 2-8, observing a significant reduction in male-exposed females compared to controls, particularly on GD 6 and 8. We also measured transitions in uterine luminal area and e-cadherin expression, as these processes are modulated by estrogens.

One of the main causes of interassay variability in flow cytometry-based assays is due to differences in gating strategies between laboratories, which may prohibit the generation of robust results within single centers and across institutions. To study how gating strategies affect the variation in reported results, a gating panel was organized where all participants analyzed the same set of Flow Cytometry Standard (FCS) files from a four-color ICS assay using their own gating protocol (Phase I) and a gating protocol drafted by consensus from the organizers of the panel (Phase II).

Here, we report probestin synthesis by solid phase peptide synthesis (SPPS) method and evaluated its activity to inhibit angiogenesis using a chicken embryo chorioallantoic membrane (CAM) assay and a CAM tumor xenograft model. Results from these studies demonstrate that probestin inhibits the angiogenic activity and tumor growth.

The primary reason for disappointing results is the nonanatomic position of the prosthesis because the normal anatomic landmarks are disrupted when fractured. An anatomic reference outside of the zone of injury may facilitate proper positioning of fracture arthroplasty reconstructions.

A microwave-mediated Sonogashira reaction was used as a key step for the synthesis of these compounds. Biological evaluation, in whole cell assays, showed that some analogs had remarkable inhibitory activity against a variety of RTKs and in particular cytotoxic activity against A431 tumor cells in culture.

Objective: To characterize beneficiaries who used a pharmacy or pharmacist as a Medicare Part D information source.
Methods: This cross-sectional descriptive study involved 4,724 Medicare Part D beneficiaries who graduated from Wisconsin high schools in 1957. The main outcome measure was beneficiary self-reported use of a pharmacy or pharmacist as a Medicare Part D information source.
This paper reviews barriers to clinical and financial integration in services for dual eligibles prior to passage of the ACA, identifies models used by states to integrate care through contract and waiver authorities available to CMS prior to passage of the ACA, describes two new demonstrations proposed by CMS through the Medicare-Medicaid Coordination Office and Innovation Center, and discusses several new models available for consideration by federal and state policymakers. These options draw on experience from existing programs and waivers to provide suggested changes to existing programs, as well as a permanent state plan option for a fully integrated, capitated care model. This model could be made available to states prior to the completion of the demonstration process begun by the Medicare-Medicaid Coordination Office and Innovation Center.

Here we characterize the organizational principles of functional vesicles at native hippocampal synapses with nanoscale resolution using fluorescent dye labeling and electron microscopy. We show that the recycling pool broadly scales with the magnitude of the total vesicle pool, but its average size is small (∼45 vesicles), highly variable, and regulated by CDK5/calcineurin activity.

Most provinces in Canada now offer regulated midwifery, but the way services are delivered across the country varies. The Canadian Midwifery Regulators Consortium has identified a need to examine the different ways in which care is being organized; this is to determine what elements are essential to maintain and where flexibility is desirable, in order to promote growth of the profession and maximize the contribution of midwifery to the provision of services. In April 2012 a planning meeting (funded by Canadian Institutes of Health Research) brought together midwifery leaders, researchers, regulators, and lead clinicians of several maternity service programs across Canada.

Design: An online program was created using an Internet-based learning platform to simulate 4 MTM meetings between a pharmacist and a virtual patient diagnosed with diabetes.
Assessment: Eighty students and 42 pharmacists completed the program.
Tuberculosis (TB) patients who do not complete treatment pose a potential public health risk. In West Yorkshire, local clinicians suspected that this risk was overestimated by the national Enhanced Tuberculosis Surveillance system. We audited patients who failed to complete treatment and were categorised as lost-to-follow-up (LTFU) between 2004 and 2008, using a combination of hand searching existing records and obtaining additional information from clinicians.

We compute the sensitivity limits of these detectors due to intrinsic phase noise of the light sources, noninertial motion of the light sources, and atomic shot noise and compare them to sensitivity limits for traditional light interferometers. We find that atom interferometers and light interferometers are limited in a nearly identical way by intrinsic phase noise and that both require similar mitigation strategies (e.

Background: Human epididymis protein 4 (HE4) is approved for clinical use with CA125 to predict epithelial ovarian cancer in women with a pelvic mass or in remission after chemotherapy. Previously reported reference ranges for HE4 are inconsistent.
Methods: We report positivity thresholds yielding 90%, 95%, 98%, and 99% specificity for age-defined populations of healthy women for HE4, CA125, and Risk of Ovarian Malignancy Algorithm (ROMA), a weighted average of HE4 and CA125.
Aims: To complete an initial estimate of the global cost of eliminating avoidable blindness, including the investment required to build ongoing primary and secondary health care systems, as well as to eliminate the 'backlog' of avoidable blindness. This analysis also seeks to understand and articulate where key data limitations lie.
Materials And Methods: Data were collected in line with a global estimation approach, including separate costing frameworks for the primary and secondary care sectors, and the treatment of backlog.
Ongoing ovarian cancer screening trials are investigating the efficacy of a two-step screening strategy using currently available blood and imaging tests [CA125 and transvaginal sonography (TVS)]. Concurrently, efforts to develop new biomarkers and imaging tests seek to improve screening performance beyond its current limits. This study estimates the mortality reduction, years of life saved, and cost-effectiveness achievable by annual multimodal screening using increasing CA125 to select women for TVS, and predicts improvements achievable by replacing currently available screening tests with hypothetical counterparts with better performance characteristics.
