Article Synopsis
  • - Nickel phosphides are effective catalysts for hydrogen production and petroleum refinement, but creating consistently-sized, pure nanoparticles has been difficult in the past.
  • - The study presents a method using trioctylphosphine (TOP) to synthesize uniform phase-pure nickel phosphide nanoparticles, with control over the composition based on the TOP-to-Ni(II) ratio.
  • - The synthesis process allows for stopping at an amorphous stage and later transforming those into uniform nanocrystals by adjusting temperature, with potential implications for synthesizing other metal compounds as well.

Objectives: To assess the effectiveness of a chaplain patient navigator in improving outcomes and reducing costs in the ICU setting.

Design: A randomized controlled trial at a large, urban, academic community hospital in Baltimore, Maryland.

Setting/patients: All patients admitted to the Johns Hopkins Bayview Medical Center Cardiac and Medical ICUs between March 2015 and December 2015.

Global migration from Africa to more economically developed regions such as the United States, Europe, the Middle East, and Australia has reached unprecedented rates in the past five decades. The size of the African immigrant population in the United States has roughly doubled every decade since 1970. However, research has not kept up with the growing size of this vulnerable population.

Effective communication between intensive care unit (ICU) staff, and patients and their families, can help increase understanding, trust, and goals-of-care decisions. Many strategies focus on enhancing communication by increasing family meetings or adding patient navigators. In our ICU, we implemented both strategies, uniquely appointing a chaplain for the patient navigator role.

Background: Pre-eclampsia with severe features (PEC) is a pregnancy-specific syndrome characterized by severe hypertension and end-organ dysfunction, and is associated with short-term adverse cardiovascular events, including heart failure, pulmonary edema, and stroke.

Objectives: The authors aimed to characterize the short-term echocardiographic, clinical, and laboratory changes in women with PEC, focusing on right ventricular (RV) systolic pressure (RVSP) and echocardiographic-derived diastolic, systolic, and speckle tracking parameters.

Methods: In this prospective observational study, the authors recruited 63 women with PEC and 36 pregnant control patients.

Providing coordinated care remains a challenge for cancer services globally. There is a lack of consensus in the literature about what constitutes successful coordinated care. This study aimed to define and prioritize a set of consensus-driven success factors that can lead to coordinated care.

Purpose: "Attending rotations" on intensive care unit (ICU) services have been in place in most teaching hospitals for decades. However, the ideal frequency of patient care handoffs is unknown. Frequent attending physician handoffs could result in delays in care and other complications, while too few handoffs can lead to provider burnout and exhaustion.

Rationale: Pathways to lung cancer diagnosis and treatment are complex. International evidence shows significant variations in pathways. Qualitative research investigating pathways to lung cancer diagnosis rarely considers both patient and general practitioner views simultaneously.

Background: There are a variety of methods for priority setting in health research but few studies have addressed how to prioritise the gaps that exist between research evidence and clinical practice. This study aimed to build a suite of robust, evidence based techniques and tools for use in implementation science projects. We applied the priority setting methodology in lung cancer care as an example.

Aim: To establish priorities for implementation research to reduce evidence-practice gaps in lung cancer care.

Methods: A modified Nominal Group Technique was used to prioritize evidence-practice gaps in lung cancer care with oncology professionals at three clinical study sites: one rural and two metropolitan. A multimethods design was used to gather quantitative and qualitative data.

HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets) is a severe variant of pre-eclampsia whose pathogenesis remains unclear. Recent evidence and clinical similarities suggest a link to atypical hemolytic uremic syndrome, a disease of excessive activation of the alternative complement pathway effectively treated with a complement inhibitor, eculizumab. Therefore, we used a functional complement assay, the modified Ham test, to analyze sera of women with classic or atypical HELLP syndrome, pre-eclampsia with severe features, normal pregnancies, and healthy nonpregnant women.

Drawing on asylum reception orders, casebooks and annual reports, as well as County Council notebooks recording the settlement of Irish patients, this article examines a deeply traumatic and enduring aspect of the Irish migration experience, the confinement of large numbers of Irish migrants in the Lancashire asylum system between the 1850s and the 1880s. This period saw a massive influx of impoverished Irish into the county, particularly in the post-Famine years. Asylum superintendents commented on the impact of Irish patients in terms of resulting management problems in what became, soon after their establishment, overcrowded and overstretched asylums.

Purpose: This literature review is to evaluate current research articles pertinent to physical therapy treatment of osteoarthritis (OA) of the knee. Osteoarthritis of the knee is an increasingly common diagnosis, with a prognosis that can lead to loss in an individual's functional abilities. Literature on the subject of OA and its physical therapy treatment is vast and current, however, obtaining and analyzing it can be time consuming and costly to a Physical Therapist.

Background: To investigate the coordination of humeral, scapular and thoracolumbar spine motions during a number of unilateral and bilateral upper limb movements in a range of movement conditions.

Methods: Thirty-two healthy women performed unilateral and bilateral arm elevations in three planes-sagittal, coronal and scapular. Scapular, humeral and spinal orientations were measured at 100 Hz using a multi-sensor, 6-degree-of-freedom electromagnetic tracking system.
