Dispersion Interactions and Vibrational Effects in Ice as a Function of Pressure: A First Principles Study

We present a first principles theoretical framework that accurately accounts for several properties of ice, over a wide pressure range. In particular, we show that, by using a recently developed nonlocal van der Waals functional and by taking into account hydrogen zero point motion, one can properly describe the zero temperature equation of state, the vibrational spectra, and the dielectric properties of ice at low pressure and of ice VIII, a stable phase between 2 and 60 GPa. While semilocal density functionals yield a transition pressure from ice XI to VIII that is overestimated by almost an order of magnitude, we find good agreement with experiments when dispersion forces are taken into account. Zero point energy contributions do not alter the computed transition pressure, but they affect structural properties, including equilibrium volumes and bulk moduli

Presenting dynamic information on mobile computers

A problem with mobile computing devices is the output of dynamic information owing to their small screens. This paper describes an experiment to investigate the use of non-speech sounds to present dynamic information without using visual display space. Results showed that non-speech sound could be used in a simple share-dealing scenario to present a “sound graph” of share prices. This allowed participants to reduce the workload they had to invest in share-price monitoring as they could listen to the graph whilst they worked in a share accumulation window

Historic landmarks in clinical transplantation: Conclusions from the consensus conference at the University of California, Los Angeles

The transplantation of organs, cells, and tissues has burgeoned during the last quarter century, with the development of multiple new specialty fields. However, the basic principles that made this possible were established over a three-decade period, beginning during World War II and ending in 1974. At the historical consensus conference held at UCLA in March 1999, 11 early workers in the basic science or clinical practice of transplantation (or both) reached agreement on the most significant contribution of this era that ultimately made transplantation the robust clinical discipline it is today. These discoveries and achievements are summarized here is six tables and annotated with references

A qualitative study of patients’ feedback about Outpatient Parenteral Antimicrobial Therapy (OPAT) services in Northern England: implications for service improvement

Objective Outpatient parenteral antimicrobial therapy (OPAT) provides opportunities for improved cost savings, but in the UK, implementation is patchy and a variety of service models are in use. The slow uptake in the UK and Europe is due to a number of clinical, financial and logistical issues, including concern about patient safety. The measurement of patient experience data is commonly used to inform commissioning decisions, but these focus on functional aspects of services and fail to examine the relational aspects of care. This qualitative study examines patients’ experiences of OPAT. Design In-depth, semistructured interviews. Setting Purposive sample of OPAT patients recruited from four acute National Health Service (NHS) Trusts in Northern England. These NHS Trusts between them represented both well-established and recently set-up services running nurse at home, hospital outpatient and/or selfadministration models. Participants We undertook 28 semistructured interviews and one focus group (n=4). Results Despite good patient outcomes, experiences were coloured by patients' personal situation and material circumstances. Many found looking after themselves at home more difficult than they expected, while others continued to work despite their infection. Expensive car parking, late running services and the inconvenience of waiting in for the nurse to arrive frustrated patients, while efficient services, staffed by nurses with the specialist skills needed to manage intravenous treatment had the opposite effect. Many patients felt a local, general practitioner or community health centre based service would resolve many of the practical difficulties that made OPAT inconvenient. Patients could find OPAT anxiety provoking but this could be ameliorated by staff taking the time to reassure patients and provide tailored information. Conclusion Services configurations must accommodate the diversity of the local population. Poor communication can leave patients lacking the confidence needed to be a competent collaborator in their own care and affect their perceptions of the service

Nurturing environments and nutrient-rich diets may improve cognitive development: analysis of cognitive trajectories from six to sixty months from the MAL-ED study (OR10-01-19)

Objectives: To identify clusters of cognitive developmental trajectories and associated differentiating factors of children aged 6 to 60 months old in 5 low to middle-income sites.Methods: We followed 835 children and assessed anthropometry at enrolment (≤ 17 d old); bi-weekly illness data (0–24 and 60 mo); non-diarrheal and diarrheal stools (0–24 mo) analyzed for a panel of enteropathogens; quantitative complementary food intakes (9–24 and 60 mo); micronutrient status (Fe, Zn, Vit A; 7, 15, and 24 mo); quality of the child\u27s home environment (6, 24, and 60 mo) and maternal reasoning ability and depressive symptoms via questionnaire. Child cognitive development was assessed by the Bayley Scales of Infant Development III (6, 15 and 24 mo) and Wechsler Preschool and Primary Scale of Intelligence (60 mo). Clusters of trajectories were identified using a latent class mixed model. Differences between clusters were described using discriminant analysis to rank the contribution of each variable using correlation-adjusted t-scores (CAT).Results: Five clusters were identified. From 51 discriminatory factors, 10 had greatest descriptive power: HOME score at 60 mo (mean CAT2 ± SD: 34.6 ± 0.35), proportion of days ill from 0–24 mo (23.9 ± 0.18), years of maternal schooling (13.8 ± 0.23), mean nutrient densities of zinc (12.3 ± 0.07), protein (8.95 ± 0.09), vitamin B6 (8.2 ± 0.10), phytate (7.91 ± 0.05) and mean energy (7.82 ± 0.04) from complementary foods (9–24 mo), % days of exclusive breastfeeding (0–6 mo; 6.42 ± 0.10) and weight-for-age at enrolment (6.14 ± 0.17). The discriminant analysis model fit was statistically significant (Wilk\u27s λ 0.54, P \u3c 0.01).Conclusions: Early life factors associated with higher scoring trajectories included stimulation and support for the child in their home, complementary feeding that typified greater diversity and animal-source foods, and maternal years of schooling. Influences associated with lower scoring trajectories included lower weight at enrolment and higher prevalence of illness. Policies promoting maternal and child nutrition, education and fostering a nurturing environment are likely to have greatest impact on child development

Creating Improved Communication Between Nursing and Physicians: Importance of Collaboration within a Hospital System

Background: Optimal communication between all members of the healthcare team is important to ensure safe and efficient patient care.Objective: To improve communication between nurses and resident physicians by developing and implementing a paging protocol.Methods: A resident-led workgroup was assembled to identify opportunities for improving communication. A survey was designed to assess current practices and perceptions related to resident and nurse communication. A facilitated focus group of residents and nurses met on two separate occasions to review the survey results and develop a set of mutually agreeable paging guidelines. The group chose to adopt the ISBARR communication tool and planned educational interventions accordingly. Residents and nurses were resurveyed roughly three months’ post-intervention.Results: The results indicated a 12.8% reduction (p=0.017) in the percentage of nurse respondents that “never” inquire whether or not another nurse on the unit needs to speak with the same physician prior to paging. A 10.3% increase (p=0.033) in resident respondents that “usually” receive grouped pages, and an 11% reduction (p=0.042) in the percentage of resident respondents that “never: receive grouped pages. However, only 53.3% (n=60) of nurse respondents and 44.1% (n=68) of resident respondents felt their ISBARR training was adequate. Moreover, only 38.4% and 30.9% of nurse and resident respondents, respectively felt the paging guidelines and ISBARR had improved overall communications between the two groups.Conclusions: While the follow-up survey results revealed some improvements in paging practices, the need for continued education was clear
