The feasibility of the story as a qualitive instrument as a narrative quality improvement method.
Background and objectiveStories from older adults give insight into their personal lives and in the care they receive. The story as a quality instrument is a narrative quality improvement method with which care professionals can interview older adults about how care is experienced. Each performed interview will be translated into a portrait containing the core themes of the shared story. The objective of this study was to assess the feasibility of and experiences with the story as a quality instrument amongst care professionals and older adults receiving long-term care.MethodsFive care locations providing nursing home care and one providing home care participated in the current study. In total 19 trained care professionals performed interviews with 52 older adults. Both the performed interviews and written portraits were scored according to preset criteria to establish the compliance to the predetermined protocol. Next to that, experiences from care professionals as insider researchers and respondents were gathered.ResultsOverall the fidelity for performing the interview was good. In 90% of cases interviewers posed one inviting open question. Following, interviewers used proposed interviewing techniques such as asking in depth questions, asking for an example or summarizing what has been said. In 20 of the interviews, the respondents input accounted for over 80% of the total number of words, and in 27 interviews the respondentsā input accounted for 60%-80%. Fidelity with the protocol for drawing up portraits was sufficient in most cases. In 66% the portrait contained all important themes and in 32% the majority of important themes. One portrait missed a significant proportion of themes mentioned during the interview. The experiences from care professionals consist of successes, challenges, added value and prerequisites.ConclusionsCare professionals were mostly capable of following the method according to protocol after being trained. The method is believed to be a promising innovation because care professionals play a key role in gathering and using stories to improve quality of care. The outcomes can be used by care professionals to learn and improve within their care location according to the quality framework for nursing home care
Analysing the Security of Google's implementation of OpenID Connect
Many millions of users routinely use their Google accounts to log in to
relying party (RP) websites supporting the Google OpenID Connect service.
OpenID Connect, a newly standardised single-sign-on protocol, builds an
identity layer on top of the OAuth 2.0 protocol, which has itself been widely
adopted to support identity management services. It adds identity management
functionality to the OAuth 2.0 system and allows an RP to obtain assurances
regarding the authenticity of an end user. A number of authors have analysed
the security of the OAuth 2.0 protocol, but whether OpenID Connect is secure in
practice remains an open question. We report on a large-scale practical study
of Google's implementation of OpenID Connect, involving forensic examination of
103 RP websites which support its use for sign-in. Our study reveals serious
vulnerabilities of a number of types, all of which allow an attacker to log in
to an RP website as a victim user. Further examination suggests that these
vulnerabilities are caused by a combination of Google's design of its OpenID
Connect service and RP developers making design decisions which sacrifice
security for simplicity of implementation. We also give practical
recommendations for both RPs and OPs to help improve the security of real world

Permeability of blood-tear barrier to fluorescein and albumin after application of platelet-activating factor to the eye of the guinea pig
One of the inflammatory responses of the eye to local application of platelet-activating factor (PAF) is oedema of the conjunctiva, caused by extravasation of plasma. Aim of the study was to investigate if fluorescein would leak from the blood into the tears together with plasma protein after application of PAF to the eye. Fluorescein was given intraperitoneally 30 min prior to application of 25 Ī¼l of 0.1% solution of PAF. Thirty min after PAF the tear film was collected by washing the surface of the eye with 25 Ī¼l of phosphate buffered saline (PBS). Fluorescein in eye washings and in plasma was measured by fluorophotometry and albumin by immunodiffusion. Both fluorescein and albumin appeared in a related fashion in tears, being absent in washings of placebo-treated control eyes. Extravasation of fluorescein can be used as a measure for plasma leakage in the conjunctiva with the advantage over the Evans Blue method that the former is a non-invasive method
On shifting ground
This research paper explores some of the transition/tension between the past and the present (old and the new) in the current socio/political transformation. Through the trajectory of my own Norwegian background, I will investigate the use of heritage and āsoftā nationalism within formation of national identity, and look at some artistsā response to the current political discourse, through both their art making or writing. By investigating two distinctive symbols of national heritage, the bunad and Borre National Park, I hope to shine light on the complicated balancing act of the dichotomy between inclusion and exclusion when embracing national identity through a common history. The bunad is an increasingly popular, semi-invented national costume, and Borre is the largest burial site from the Viking era in Scandinavia. Furthermore, I will also explore social anthropological thinking around Eric Hobsnawnās concept of āthe invention of traditionā. The paper will look at the significance of the landscape and geographical identity, as well as the symbioses between place and the concept of the nation state. Inserted into this, I will discuss some of the outcomes from the intense changeover from analogue technologies to the digitalāgenerating new practices working across the mediums of photography, film/video and the digital. The hybrid medium specificity of the still-motion is of particular interest to my art practice. This video-formatted offspring of the slideshow allows for an expansion of the photographic medium, by viewing it through a cinematic frame, and in the process generating new narrative opportunities and registration of time. Finally, all the concerns articulated in this research will inform my final artwork exhibited in the SCA Postgraduate Degree show in December 2014; a two-piece video installation entitled On Shifting Ground
Effects of switching to PI monotherapy on measures of lipoatrophy: meta-analysis of six randomized HIV clinical trials
Background: Switching from triple combination treatment to protease inhibitor (PI) monotherapy may prevent or reverse adverse events related to long-term nucleoside analogues. Lipoatrophy is associated with long-term use of thymidine analogues (zidovudine and stavudine). Methods: A detailed MEDLINE search was conducted to identify randomised clinical trials of triple combination treatment versus PI monotherapy. Summary results from analysis of changes in body composition (DEXA analysis) were collected: the mean change in limb fat and trunk fat to Week 48 or 96, and the percentage of patients with lipoatrophy (20% reduction from baseline in limb fat) or lipohypertrophy (20% rise from baseline in trunk fat). Results: Six randomised trials of PI monotherapy versus triple therapy with data on body composition changes, measured by DEXA scanning at baseline and Week 48 or 96, were identified: Abbott-613 (LPV/r vs ZDV/3TC/EFV, induction-maintenance trial, n=105), Monark (LPV/r vs ZDV/3TC/LPV/r, first-line trial, n=63), Kalesolo (LPV/r vs LPV/r +2NRTIs, switch trial, n=42), MONOI (DRV/r vs DRV/r + 2NRTIs, switch trial, n=156), MONARCH (DRV/r vs DRV/r + 2NRTIs, switch trial, n=30) and KRETA (LPV/r vs LPV/r + ABC/3TC, switch trial, n=74). In the meta-analysis, there were greater rises in limb fat in the PI monotherapy arms than the triple therapy arms (mean difference =277g, 95% CI=+36 to+517g, p=0.024). The percentage of patients with lipoatrophy was significantly lower in the PI monotherapy arms (4%) than the triple therapy arms (20%), (p=0.0005). There was no difference between PI monotherapy and triple therapy for mean change in trunk fat (mean difference=−73g, 95% CI = −621 to +475g, p=ns). There was also no significant difference in the risk of lipohypertrophy between the PI monotherapy arms (32%) and the triple therapy arms (27%) (p=ns). In each of the four analyses, there was no evidence for heterogeneity of treatment effects between the trials (Cochran's Q tests, p=ns for each comparison). Conclusions: In this meta-analysis, the risk of lipoatrophy was significantly lower for patients taking PI monotherapy, compared to triple therapy. There was no significant difference between the arms for lipohypertrophy. However, several of the trials included zidovudine in the control arm, which carries a higher risk of lipoatrophy than tenofovir and abacavir, which are now more widely used
New Measures for Predicting Birth-Related Pelvic Floor Trauma.
OBJECTIVES: The aim of this study was to establish the predictive role of obstetric variables for obstetric outcomes and birth related levator ani muscle (LAM) trauma. METHODS: In this prospective study, women underwent 3-dimensional pelvic floor ultrasound at their first appointment at 36 weeks and also 3 months postpartum. The measurements included minimal levator hiatus circumference (MLHC) and the ratio of fetal head circumference to MLHC = head-induced stretch ratio (HISR) as an indicator of the discrepancy between passage and passing canal. To derive the true impact of baby's mass on the levator ani musculature, we devised the levator ani stretch ratio (LASR), which was calculated by multiplying the HISR and the baby's weight. RESULTS: Data set of 173 women was available for analysis. Mean HISR and LASR values were statistically different across all binary outcome categories, with 1 exception for HISR and levator ani injury. The odds ratios for LASR indicated positive and statistically significant associations with all obstetric outcomes examined. The probability of the LASR correctly classifying those with the adverse obstetric outcome, as estimated by the area under the curve, ranged from 0.64 to 0.80 with the strongest discriminatory ability observed for severe LAM trauma. CONCLUSIONS: Fetal head circumference/mother MLHC ratio (HISR) is associated with longer length of second stage of labor, assisted delivery, and increased severity of perineal trauma. Similar associations were observed for LASR, but in addition, LASR had good discriminatory ability to identify severe LAM trauma
Oscillatory Tunnel Splittings in Spin Systems: A Discrete Wentzel-Kramers-Brillouin Approach
Certain spin Hamiltonians that give rise to tunnel splittings that are viewed
in terms of interfering instanton trajectories, are restudied using a discrete
WKB method, that is more elementary, and also yields wavefunctions and
preexponential factors for the splittings. A novel turning point inside the
classically forbidden region is analysed, and a general formula is obtained for
the splittings. The result is appled to the \Fe8 system. A previous result for
the oscillation of the ground state splitting with external magnetic field is
extended to higher levels.Comment: RevTex, one ps figur
