Metastable layered lithium-rich niobium and tantalum oxides nearly instantaneous cation exchange.

Lithium-rich early transition metal oxides are the source of excess removeable lithium that affords high energy density to lithium-rich battery cathodes. They are also candidates for solid electrolytes in all-solid-state batteries. These highly ionic compounds are sparse on phase diagrams of thermodynamically stable oxides, but soft chemical routes offer an alternative to explore new alkali-rich crystal chemistries.

Leadership Development Recommendations for Clinical Nurse Managers to Bolster the Postpandemic Workforce.

The postpandemic atmosphere has created a perfect storm that has necessitated a renewed prioritization to bolster support for the role of the clinical nurse manager. Role transition, competencies, mentorship, and ongoing development for the clinical nurse manager have been solidly supported in nursing leadership literature for decades. Preparing competent, ready-to-respond, people-oriented, transformational nurse leaders for these positions is essential to survival of our health care workforce.

Building on Early Coronavirus (COVID-19) Pandemic Orientation Modifications to Improve Competency Validation for Newly Hired New-to-Practice and Experienced Nurses.

Nursing professional development and human resource leaders revised general nursing orientation content and structure based on changes because of COVID-19 in length, focus, and platforms from the early stages of the pandemic. The aim of this quality improvement project was to incorporate best of pandemic modifications with key stakeholders and new-to-practice and experienced nursing hire needs emerging from COVID-19 realities on the workforce. The benefit for nursing professional development practitioners is relatability of general nursing orientation revisions for sustainability of clinical excellence and safety.

Pressure-Temperature Phase Diagram of Lithium, Predicted by Embedded Atom Model Potentials.

In order to study the performance of interatomic potentials and their reliability at higher pressures, the phase diagrams of two different embedded-atom-type potential models (EAMs) and a modified embedded-atom model (MEAM) of lithium are compared. The calculations were performed by using the nested sampling technique in the pressure range 0.01-20 GPa, in order to determine the liquid-vapor critical point, the melting curve, and the different stable solid phases of the compared models.

Thermodynamics and the potential energy landscape: case study of small water clusters.

We investigated the structure and the thermodynamic properties of small water clusters with the nested sampling computational technique, using two different water models, the coarse-grained mW (up to 25 molecules) and the flexible version of the TIP3P (up to 16 molecules). By mapping the entire potential energy landscape of the clusters, we calculated the heat capacity curves, located the structural transitions and identified those local minimum basins which contribute the most to the total partition function. We found that in the case of the mW model, trends in first-order-like and continuous-like transitions can be very well matched to the characteristics of the landscape: cluster sizes with fewer and narrower local minimum basins show a sharper 'melting' peak on the heat capacity curve.

The impact of lifetime drug use on hepatitis C treatment outcomes in insured members of an integrated health care plan.

Background: The relation of drug use to HCV treatment outcome in an insured household population has not been previously reported.

Methods: Lifetime frequencies of marijuana use and non-medical use of stimulants, sedatives, and opioids; hallucinogens; and inhalants were retrospectively assessed in 259 privately insured members of an integrated health care plan treated for chronic hepatitis C virus infection (HCV+) with pegylated interferon alpha and ribavirin and examined with respect to rates of sustained virological response (SVR).

Results: The majority of patients reported chronic use of multiple illegal drugs; 61.

'You're HIV positive': perinatally infected young people's accounts of the critical moment of finding out their diagnosis.

This paper presents the recollections of 28 young people (15-24 years old) of formally learning that they had acquired HIV perinatally. Prior to the naming of their illness, many participants had experienced repeated biographical disruption through ill health and other major life events. However, the critical moment in their HIV trajectory was when they were told their diagnosis.

The impact of lifetime alcohol use on hepatitis C treatment outcomes in privately insured members of an integrated health care plan.

Unlabelled: Treatment of chronic hepatitis C infection (HCV(+) ) has historically been shown to be less effective in patients with a heavy drinking history. The effect of moderate and heavy alcohol use on treatment with pegylated interferon-alpha and ribavirin (P/R) in an insured household population has not been previously reported. We investigated the effect of alcohol on treatment outcome in a cohort of 421 treatment-naïve HCV(+) patients, members of an integrated health care plan treated with P/R between January 2002 and June 2008.

The Bimetric cementless total hip replacement: 7-18 year follow-up assessing the influence of acetabular design on survivorship.

The purpose of this study was to evaluate the mid- to long-term survivorship of Bimetric cementless total hip replacement and assess how it is affected by the acetabular design. This was a retrospective analysis of 127 Bimetric cementless total hip replacements in 110 patients with a follow-up of 7-18 years. A single design stem and three different cementless metal-backed acetabular designs were used.

Percutaneous dynamic hip screw.

We present the results of a technique of dynamic hip screw insertion through a very small incision, typically 2-2.5 cm. The technique is performed using a standard dynamic hip screw set and requires no additional equipment.

The AO unreamed nail: friend or foe.

Twenty-nine tibial shaft fractures were stabilized with the AO unreamed tibial nail. These included 13 type A fractures, 11 type B fractures and five type C injuries. Fourteen of the fractures were open.

Arteriovenous fistula after fibular osteotomy leading to recurrent haemarthroses in a total knee replacement.

We present a patient with an arteriovenous fistula of the peroneal artery acquired after a left dome tibial osteotomy with midshaft fibular osteotomy. He had subsequently had a total knee replacement on that side. The arteriovenous malformation was only diagnosed when he represented with symptoms and signs of venous hypertension with sterile recurrent haemarthroses in the left knee.

Closing the audit circle: effect of continuing audit on arthroscopic practice.

A prospective study in a single orthopaedic unit for one calendar year was carried out to examine the effect of continuing audit on arthroscopic practice. A standard proforma was introduced to record information and results were analysed using a system of audit codes. Two audit periods were examined, the first 3 months and the subsequent 9 months.

The torn acetabular labrum.

Eleven patients with tears of the acetabular labrum are discussed and the syndrome of the torn labrum is defined. In all cases the lesion was associated with acetabular dysplasia, and a constant early radiological sign was a cyst in the lateral aspect of the acetabulum. The diagnosis was confirmed by arthrography.
