Nanocrystalline samples of Ni0.3Zn0.4Co0.2Cu0.1Fe2O4 (NZCCF) are prepared by a simple co-precipitation method. To obtain nanoparticles of different sizes, the as prepared sample is annealed at 400, 600, 800 and 1000 °C. Nanoparticles of the sample annealed at 600 °C are encapsulated in multi-walled carbon nanotubes (MWCNT). To confirm the crystallographic phase, x-ray diffraction (XRD) patterns are analyzed by the Rietveld method and cation distribution in A- and B-sites is estimated from the analysis. Occupancy of Zn(2+) ions in A-site and that of Fe(3+) ions in B-site increase with the increase of annealing temperature (T A) and lattice parameters lie within 8...

Introduction Despite strong evidence supporting the benefit of 17-alpha hydroxyprogesterone caproate (17P) in preventing recurrent preterm birth, this treatment still does not reach most eligible patients. This study sought to identify approaches to measuring the appropriate use of 17P, with the goal of helping health systems better monitor and improve the implementation of this intervention. Methods Semi-structured telephone interviews were used to gather data on measures for 17P use being developed and implemented by state team members participating in the Infant Mortality Collaborative Improvement and Innovation Network (IM CoIIN)-a national quality improvement initiative...

PURPOSE: The use of oral anticoagulation (OAC) in the elderly population with atrial fibrillation (AF) treated in long-term care (LTC) facilities is inconsistent. We examined the magnitude and sources of the gap between indicated and prescribed OAC in the elderly population with AF. METHODS: We retrospectively scanned the electronic medical record (EMR) and pharmacy data of 25 LTC facilities in Ontario, Canada. The diagnosis of AF was drawn from EMR. Different attributable risk factors for possible failure to prescribe OAC were examined...

BACKGROUND: Critical illness polyneuropathy (CIN) and critical illness myopathy (CIM), together "ICU-Acquired weakness (ICUAW)," occur frequently in septic patients. One of the proposed mechanisms for ICUAW includes prolonged inactivation of sodium channels. Propofol, used commonly in patients with acute respiratory failure (ARF), primarily acts via enhancement of GABAergic transmission but may also increase sodium channel inactivation, suggesting a potential interaction. METHODS: Electronic medical records and EMG reports of patients with ICUAW and a diagnosis of either sepsis, septicaemia, severe sepsis, or septic shock, concurrent with a diagnosis of acute respiratory failure (ARF), were retrospectively analyzed in a single center university hospital...

Maintaining weight loss is a significant challenge in combating obesity. The goal of Maintaining Activity and Nutrition through Technology-Assisted Innovation in Primary Care (MAINTAIN-pc) is to evaluate the use of tools delivered through an electronic health record (EHR) and patient portal, with or without health coach support, to help primary care patients maintain weight loss. EHR tools include flowsheets, standardized surveys, and secure patient messaging. Inclusion criteria were age 18-75years, voluntary 5% weight loss in the past 2years with prior BMI≥25kg/m(2), and no bariatric procedures in past 5years...

Hospital admissions related to burn injury reach 40,000 annually. Patients who experience extensive burns require longer hospital stays and are at increased risk for infection and hospital acquired conditions. This comparative case study is a two patient matched case control design that follows the hospital course of two children who experienced burn injuries. For one of these patients, with the consent of the child's parents, the grandmother treated her granddaughter with essential oils. Essential oils have the potential to inhibit microbial growth, support treatment of wounds, and facilitate healing...

Electron energy-loss magnetic chiral dichroism (EMCD) spectroscopy, which is similar to the well-established X-ray magnetic circular dichroism spectroscopy (XMCD), can determine the quantitative magnetic parameters of materials with high spatial resolution. One of the major obstacles in quantitative analysis using the EMCD technique is the relatively poor signal-to-noise ratio (SNR), compared to XMCD. Here, in the example of a double perovskite Sr2FeMoO6, we predicted the optimal dynamical diffraction conditions such as sample thickness, crystallographic orientation and detection aperture position by theoretical simulations...

Otitis media is a common, generally self-limiting childhood illness that can progress to severe disease and have lifelong sequelae, including hearing loss and developmental delays. Severe disease is disproportionately prevalent among Aboriginal and Torres Strait Islander children. Primary health care is at the frontline of appropriate prevention and treatment. Continuous quality improvement in the prevention and management of important causes of morbidity in client populations is accepted best practice in primary health care and now a requirement of Australian Government funding to services providing care for Aboriginal and Torres Strait Islander children...

OBJECTIVE: Inefficient navigation in electronic health records has been shown to increase users' cognitive load, which may increase potential for errors, reduce efficiency, and increase fatigue. However, navigation has received insufficient recognition and attention in the electronic health record (EHR) literature as an independent construct and contributor to overall usability. Our aims in this literature review were to (1) assess the prevalence of navigation-related topics within the EHR usability and safety research literature, (2) categorize types of navigation actions within the EHR, (3) capture relationships between these navigation actions and usability principles, and (4) collect terms and concepts related to EHR navigation...

Feeding management factors have great potential to influence activity patterns and feeding behavior of dairy cows, which may have implications for performance. The objectives of this study were to assess the effects of feed push-up frequency on the behavioral patterns of dairy cows, and to determine associations between behavior and milk yield and composition. Lactating Holstein dairy cows (n = 28, parity = 1.9 ± 1.1; mean ± SD) were housed in tiestalls, milked twice per day, and offered ad libitum access to water and a total mixed ration (containing, on a dry matter basis: 25% corn silage, 25% grass/alfalfa haylage, 30% high-moisture corn, and 20% protein/mineral supplement), provided twice per day...

Unstable medial malleolar fractures are treated with either standard open reduction internal fixation (ORIF) or a percutaneous approach. The percutaneous approach avoids the potentially excessive soft tissue dissection associated with an open approach but can also result in inadequate anatomic reduction. No studies have compared the incidence of radiographic healing of medial malleolar fractures between an open approach and percutaneous fixation. A retrospective comparative study was performed at a single institution across multiple sites...
