The Family of LiCo6P4 Type Compounds – Trends in Electronic Structure and Chemical Bonding
Authors: Matar Samir F. , Pöttgen Rainer 
Published: May 2014

AbstractSelected ternary compounds of the family of AT6X4 (LiCo6P4‐type) intermetallics were studied by ab initio methods with respect to their electronic structures and chemical bonding. The bonding characteristics highlight the role of the three‐dimensional [T6X4] polyanionic networks which, within the hexagonal channels, accommodate loosely bonded A cations. In alkali metal based compounds, when T is replaced by indium (e.g. in KIn6Au4) the reverse occupancy leads to positively charged In (ca. +0.5) and negatively charged Au (ca. –0.9). Peculiar magnetic behavior is traced out whereby a magnetic order is identified only when T is a 3d element, which polarizes and induces a negative small moment on A (U) as in UCr6P4 oppositely to CeRh6X4 for X = Si, Ge.

Published: May 2014

AbstractBackgroundThe impact of laparoscopic sleeve gastrectomy (LSG) on various co‐morbidities including type II diabetes mellitus, hypertension, and sleep apnea is well established. However, its effect on hypothyroidism has not been given due attention evidenced by the scant literature on the subject. The purpose of this report is to assess the change in thyroxine (T4) requirement in morbidly obese patients with clinical hypothyroidism after LSG.MethodsWe conducted a retrospective review of morbidly obese patients on T4 replacement therapy for clinical hypothyroidism who underwent LSG from August 2009 to July 2012 at our institution.ResultsOf the 200 patients who underwent LSG during this period, 21 (10.5 %) were on T4 replacement therapy preoperatively for clinical hypothyroidism. Two patients were lost to follow‐up. The remaining 19 patients were categorized into two groups. Group 1 comprised 13 patients with decreased T4 requirements after LSG. Group 2 comprised six patients in whom the T4 dose remained unaltered. The mean change in T4 requirement in group 1 was 42.07 % (12–100 %). Group 1 patients had a significantly higher mean preoperative body mass index (48.7 vs. 43.0 kg/m2; p = 0.03) than the group 2 patients. There was a significant correlation between the percentage excess weight loss and the percentage change in T4 requirement in group 1 (r = 0.607, p = 0.028).ConclusionsSleeve gastrectomy has a favorable impact on hypothyroid status as seen by a reduction in T4 requirement in the majority of morbidly obese patients with overt hypothyroidism.

Abstract
In lower-income settings, women more often than men justify intimate partner violence (IPV). Yet, the role of measurement invariance across gender is unstudied. We developed the ATT-IPV scale to measure attitudes about physical violence against wives in 1,055 married men and women ages 18–50 in My Hao district, Vietnam. Across 10 items about transgressions of the wife, women more often than men agreed that a man had good reason to hit his wife (3 % to 92 %; 0 % to 67 %). In random split-half samples, one-factor exploratory factor analysis (EFA) (N1 = 527) and confirmatory factor analysis (CFA) (N2 = 528) models for nine items with sufficient variability had significant loadings (0.575–0.883; 0.502–0.897) and good fit (RMSEA = 0.068, 0.048; CFI = 0.951, 0.978, TLI = 0.935, 0.970). Three items had significant uniform differential item functioning (DIF) by gender, and adjustment for DIF revealed that measurement noninvariance was partially masking men’s lower propensity than women to justify IPV. A CFA model for the six items without DIF had excellent fit (RMSEA = 0.019, CFI = 0.994, TLI = 0.991) and an attitudinal gender gap similar to the DIF-adjusted nine-item model, suggesting that the six-item scale reliably measures attitudes about IPV across gender. Researchers should validate the scale in urban Vietnam and elsewhere and decompose DIF-adjusted gender attitudinal gaps.

Published: May 2014

Abstract
Background: Appropriate indications for radiologic evaluation of central venous ports are not fully understood. We aimed to quantitatively assess the utility of clinical history and imaging in the evaluation of malfunctioning central venous ports.
Methods: Clinical history, plain radiographs, and line injections intended to evaluate central venous port malfunction in 153 consecutive cases over a nearly 4-year period were retrospectively reviewed by 2 radiologists. Radiographs and line injections were separately categorized as normal or abnormal, and a consensus was reached on the final imaging diagnosis. The likelihood of a port-related abnormality necessitating immediate intervention was determined for all represented combinations of clinical history, radiographic findings, and line injection results.
Results: A radiologic diagnosis was made in 96.1% of cases; 19.7% of these diagnoses were classified as critical, requiring prompt intervention. Very low risk histories had a 0.0% incidence of critical port abnormalities in our cohort, regardless of imaging findings. Low risk histories had a 10.5% incidence of a critical abnormality and were best evaluated either by line injection, either directly or following an abnormal chest radiograph. Intermediate and high risk histories were associated with a 30.5% and 61.1% incidence of critical port abnormalities, respectively, and were best evaluated by line injection without preceding chest radiograph.
Conclusions: There are several scenarios in which imaging does not meaningfully affect management of malfunctioning central venous ports. Recognizing these inefficiencies may allow for more appropriate and cost-effective use of radiographs and line injections to evaluate the cause of port malfunction.
The AccuCath Intravenous Catheter System With Retractable Coiled Tip Guidewire and Conventional Peripheral Intravenous Catheters: A Prospective, Randomized, Controlled Comparison
Authors: Idemoto Bette K. , Rowbottom James R. , Reynolds James D. , Hickman Ronald L. 
Published: May 2014

Abstract
Background: Current peripheral intravenous catheter (PIV) first attempt success averages 47%, complications 47%, and dwell time 44 hours. Multiple intravenous (IV) access lines requiring replacement during each admission result in poor satisfaction and unnecessary costs. With 2011 Infusion Nursing Society standards allowing IV lines to dwell until complication, there is incentive to explore improvement opportunities.
Purpose: A new, proprietary coiled tip guidewire PIV was compared with conventional IV catheters in adult patients. The experimental IV catheter was projected to have a higher rate of successful placement on first attempt, fewer complications, longer dwell times, higher completion of therapy, higher user satisfaction, and lower overall costs than conventional catheters.
Methods: Adult patients requiring nonemergent IV catheters provided consent and were enrolled and randomized. The study, conducted over 4 months, included 248 patients (experimental IV group n =123, conventional IV group n =125).
Results: Experimental IV first attempt success was 89% compared with 47% for the conventional catheter. Fifty percent of conventional IV placements required a second attempt. Experimental IV complications occurred 8% of the time and complications occurred with the conventional catheter 52% of the time. Completion of therapy was 89% with the experimental IV versus 34% with the conventional IV (P &lt; .001). Dwell time improved with the experimental IV (mean 4.4 days [105 hours] vs conventional IV at 1.5 days [35 hours]) (P &lt; .001). Overall patient satisfaction using a 5-point Likert scale scored an average of 4.5 with the experimental IV compared with the conventional IV, which scored 3.
Conclusions: A new, proprietary coiled tip guidewire-delivered PIV demonstrated clear superiority over the conventional catheter in our study. Clinical outcome results showed statistically significant improvements in first attempt success, complications, completion of therapy, dwell time, and overall patient satisfaction.
Persistent Left Superior Vena Cava

Published: May 2014

Abstract
This is a case report of an incidental diagnosis of persistent left superior vena cava (PLSVC). The diagnosis was suspected after a peripherally inserted central catheter (PICC) was placed and a postinsertion chest radiograph was conducted. PLSVC is a vascular anomaly that is usually diagnosed as an incidental finding. Here, we discuss the tests performed to confirm the diagnosis and the 3 variants of PLSVC. Nurses who place PICCs are likely to run across this abnormality on postinsertion chest radiograph and knowing the diagnostic test to order to confirm the diagnosis is key in expediting patient care.

AbstractObjectiveThe emergency preparedness of residents of North Carolina and Montana were compared.MethodsGeneral preparedness was evaluated using responses to 4 questions related to a household's 3-day supply of water, 3-day supply of nonperishable food, a working battery-operated radio, and a working battery-operated flashlight. Each positive answer was awarded 1 point to create an emergency preparedness score that ranged from 0 (minimum) to 4 (maximum). Results were assessed statistically.ResultsThe average emergency preparedness score did not differ between the 2 states (P = .513). One factor influencing higher preparedness in both states was being male. Other influencing factors in North Carolina were older age, being a race/ethnicity other than white, having an annual income of $35 000 or more, having children in the household, better (excellent/very good/good) self-reported health, and not being disabled. In contrast, other factors influencing higher emergency preparedness in Montana were having a college degree and being married or partnered.ConclusionsA divergence was found in factors influencing the likelihood of being prepared. These factors were likely a result of different sociodemographic and geographic characteristics between the 2 states. (Disaster Med Public Health Preparedness. 2014;0:1-4)
IN RE A: SEVERING THE CONJOINED TWINS IN JEWISH LAW
Authors: Enker Arnold N. 
Published: May 2014

AbstractIn re A was decided by the English courts in 2000. Twin girls, named Jodie and Mary for purposes of the decision, were born joined together at their lower extremities. Jodie's heart and lungs were more or less healthy. But Mary's were insufficiently developed and could not provide her with the flow of blood and oxygen needed to survive. However, the girls shared a single circulatory system so that Jodie's heart pumped blood that flowed through both their bodies. In this manner, Jodie's heart and lungs kept Mary alive. According to the doctors, this situation could continue for a period of three to six months, or a bit longer, at the most. As the girls grew, Jodie would be unable to provide sufficient blood and oxygen to support both Mary and herself. Both would die. The doctors recommended surgical separation of the two girls. Mary would necessarily die “within minutes,” being cut off from her source of sustenance. Jodie would have a good chance of surviving. The legal issue presented was whether the doctors may perform the surgery that would cause Mary's death. At issue were questions concerning the scope of self-defense and necessity. In the course of the Court's opinions, brief reference was made to Jewish law. This article considers the Jewish law sources that bear on these issues.
Allelic variance at the vernalization gene locus Vrn-D1 in a group of sister wheat (Triticum aestivum) lines and its effects on development

SUMMARYThree groups of genes, Vrn, Ppd and Eps, control life-cycle duration in wheat (Triticum aestivum L.). The duration of a developmental phase between two stages is important for freezing resistance, heading time, anthesis and ripening date as well as yield component generation. The aim of the current study was to assess the effect of Vrn-D1 on wheat development. The vernalization genes Vrn-A1, -B1, -D1, -B3, photoperiod gene Ppd-1 and candidate genes Mot1 and FtsH4 for Eps in ‘G883’, ‘Pumai 9’ and their offspring, a group of sister lines (SLs) derived from an advanced generation, were genotyped using specific molecular markers. All detected loci were the same in the SLs and their parents except the Vrn-D1 locus. Three developmental traits, spike differentiation process, heading date and final leaf number on the main stem, were characterized in three sowing date treatments in the field. When temperatures increased, cultivars/lines carrying the dominant Vrn-D1 gene entered each spike differentiation process faster than those with the recessive vrn-D1 in the same sowing date treatment. Lines carrying Vrn-D1 had smaller final leaf number on the main stem than those with vrn-D1, and the heading dates of the former were earlier than those of the latter, especially in the fourth treatment, sown on 23 February 2012. These data suggest that Vrn-D1 confers a spring habit on wheat and the vrn-D1 confers a cold, hardy winter habit. The Vrn-D1 alleles play very important roles in semi-winter and tender spring wheat cultivars, especially in warm weather in Henan, China. Regulating developmental traits by tracing Vrn-D1 and getting an ideal combination of Vrn alleles to accommodate different wheat zones is a key role for future wheat molecular breeding.
Soil water content, runoff and soil loss prediction in a small ungauged agricultural basin in the Mediterranean region using the Soil and Water Assessment Tool

Published: May 2014

SUMMARYThe aim of the present work was to evaluate the possibilities of using sub-basin data for calibration of the Soil and Water Assessment Tool (SWAT) model in a small (46 ha) ungauged basin (i.e. where the water flow is not systematically measured) and its response. This small basin was located in the viticultural Anoia-Penedès region (North-east Spain), which suffers severe soil erosion. The data sources were: daily weather data from an observatory located close to the basin; a detailed soil map of Catalonia; a 5-m resolution digital elevation model (DEM); a crop/land use map derived from orthophotos taken in 2010 and an additional detailed soil survey (40 points) within the basin, which included properties such as texture, soil organic carbon, electrical conductivity, bulk density and water retention capacity at −33 and −1500 kPa. A sensitivity analysis was performed to identify and rank the sensitive parameters that affect the hydrological response and sediment yield to changes of model input parameters. A 1-year calibration and 1-year validation were carried out on the basis of soil moisture measured at 0·20-m intervals from depths of 0·10 to 0·90 m in two selected sub-basins, and data related to estimations of runoff and sediment concentrations in runoff collected in the same sub-basins. The present paper shows a methodological approach for calibrating SWAT in small ungauged basins using soil water content measurements and runoff samples collected within the basin. The SWAT satisfactorily predicted the average soil water content, runoff and soil loss for moderate intensity events recorded during the study periods. However, it was not satisfactory for high-intensity events which would require exploring the possibilities of using sub-daily information as an input model parameter.

BackgroundGenetic variation in the gene encoding ZNF804A, a risk gene for schizophrenia, has been shown to affect brain functional endophenotypes of the disorder, while studies of white matter structure have been inconclusive.MethodWe analysed effects of ZNF804A single nucleotide polymorphism rs1344706 on grey and white matter using voxel-based morphometry (VBM) in high-resolution T1-weighted magnetic resonance imaging scans of 62 schizophrenia patients and 54 matched healthy controls.ResultsWe found a significant (p < 0.05, family-wise error corrected for multiple comparisons) interaction effect of diagnostic group x genotype for local grey matter in the left orbitofrontal and right and left lateral temporal cortices, where patients and controls showed diverging effects of genotype. Analysing the groups separately (at p < 0.001, uncorrected), variation in rs1344706 showed effects on brain structure within the schizophrenia patients in several areas including the left and right inferior temporal, right supramarginal/superior temporal, right and left inferior frontal, left frontopolar, right and left dorsolateral/ventrolateral prefrontal cortices, and the right thalamus, as well as effects within the healthy controls in left lateral temporal, right anterior insula and left orbitofrontal cortical areas. We did not find effects of genotype of regional white matter in either of the two cohorts.ConclusionsOur findings demonstrate effects of ZNF804A genetic variation on brain structure, with diverging regional effects in schizophrenia patients and healthy controls in frontal and temporal brain areas. These effects, however, might be dependent on the impact of other (genetic or non-genetic) disease factors.
Problematising care burden research
Authors: PURKIS MARY ELLEN , CECI CHRISTINE 
Published: May 2014

ABSTRACTIn this paper we use Alvesson and Sandberg's strategy of problematisation to analyse the assumptions embedded in the development and use of the concept of ‘care-giver burden’. We do this in order to develop an explanation as to why decades of research into the experience of providing home-based care to a family member with dementia has had little effect in relieving or reducing the ‘burden’ of that care. Though some part of this is undoubtedly political, our analysis suggests that key assumptions of the research limit both knowledge development and intervention effectiveness. Especially problematic are first, an overriding focus on the isolated care-giver–recipient dyad as the appropriate object of inquiry and target of intervention, and second, an absence of an analysis of the materiality of care and care-giving practices. The heterogeneity of care situations, including interrelations among people, technologies, objects, spaces and other organisational worlds, appear in much of the research primarily as methodological problems, variables to be subdued through a more rigorous application of method. The high volume of research and acknowledged low impact of interventions, however, suggests that rethinking the nature of care practices, and how we come to know about them, is necessary if we are to develop and implement strategies that will contribute to better outcomes for people.

Published: May 2014

ABSTRACTUsing an interdisciplinary model of financial planning, we investigated the factors contributing to perceived adequacy of retirement savings among Hong Kong workers by replicating a previous study of American and Dutch workers. The model was also tested for age differences in the way in which the variables operated within the model. These questions were examined using data from a phone survey conducted with 999 Hong Kong workers in 2012. We examined three psychological factors (future time orientation, goal clarity and financial knowledge), three social support variables (early learning from parents, spousal support and friend support) and three institutional factors (quality of employer pensions, trust in banks and fund managers, and trust in the government), as well as retirement savings planning activity and perceived retirement savings adequacy. Path analyses were used to test the model for the whole sample and separately for younger (N=437) and older (N=562) workers. Although a few age differences were found in the path analyses, the model was found to be useful in explaining the factors contributing to retirement savings planning and practices. Finally, we discuss how our findings differ from those of prior studies, and we assess their theoretical and practical implications.
Re-conceptualising the status of residents in a care home: older people wanting to ‘live with care’
Authors: COOK GLENDA , THOMPSON JULIANA , REED JAN 
Published: May 2014

ABSTRACTThe construction of a meaningful life depends upon satisfying ‘fundamental human needs’. These are broadly categorised as: physical, social and self-actualisation needs that every human experiences. Some fundamental human needs satisfiers, such as ‘home’, are synergic, addressing more than one need. For an older person, the move to a care home compromises their ontological security (through disruption of identification with place and control over environment) that one's own ‘home’ provides. This paper explores the complex issues surrounding the residential status of care home residents in terms of fundamental human needs. The methodology utilised was hermeneutic phenomenology. Eight older residents participated in the study, and each resident was interviewed up to eight times over a period of six months. Narrative analysis was used to interpret how participants viewed their experiences and environment. Five themes emerged from the narratives that collectively demonstrate that residents wanted their residential status to involve ‘living with care’ rather than ‘existing in care’. The five themes were: ‘caring for oneself/being cared for’; ‘being in control/losing control’; ‘relating to others/putting up with others’; ‘active choosers and users of space/occupying space’ and ‘engaging in meaningful activity/lacking meaningful activity’. This study indicates that if care homes are to achieve synergic qualities so residents are able to regard care homes as ‘home’, then care home staff may need to be more focused on recognising, acknowledging and supporting residents' aspirations regarding their future lives, and their status as residents.
