An exploration of the nurse's experience of nursing the outlier patient in the acute care setting: Using a hermeneutic phenomenological approach

Outlier patients are currently experienced by nurses nursing within acute care settings when patients end up in the “wrong bed …in a ward inappropriate for their condition… (and they) are less likely to receive the specialist medical and nursing attention that their condition needs” (Garling, 2008, p. 990). An example of the outlier patient would be a renal patient placed in a gynaecology ward. Hermeneutic phenomenology highlighted a humanistic way of understanding the phenomenon of nursing the outlier patients. Eleven registered nurses were recruited to participate in-depth interviews. Interpretation of participant’s transcripts and the analysis process was informed by Heidegger’s (1962) Being and Time, together with Merleau-Ponty’s (2005) and van Manen’s (2001) discussion on temporality and spatiality. The study findings revealed that some nurses were becoming less capable of 1) synchronising nursing rhythms, 2) practising with disease and/ or condition specific familiarity, 3) prioritising each nursing task, 4) predicting, and 5) practicing with inter-professional relationality as they were nursing the outlier patients when compared to nursing specialty-appropriate patients. Such disruptions disconnected the nurse from her sense of being an integrated part of the system and compounded the already-existing pressures that nurses experience in the current economic rationalist work environment

Consumer Purchase Decision in Instagram Stores:The Role of Consumer Trust

Instagram, a prominent social networking site, has become a popular online shopping platform among young people. In this study, we have attempted to understand what drives people to purchase in virtual stores on Instagram. Specifically, we built upon the integrative framework of trust and identified three groups of factors explaining consumer trust in Instagram stores: trustworthiness of Instagram stores (i.e., perceived benevolence, perceived integrity, and perceived competence), propensity to trust, and external environment (i.e., Key Opinion Leader (KOL) endorsement and peer customer endorsement). These factors are expected to influence consumer trust in Instagram stores, and trust in turn determines consumer intention to purchase. The model was empirically tested with 157 Instagram users. Perceived benevolence, perceived integrity, and KOL endorsement were found to be significant factors affecting consumer trust in Instagram stores, and trust was found to have a strong relationship with consumer purchase intention. The results of this study are expected to advance the trust literature in the context of social commerce and to offer practical guidelines to Instagram storeowners

Evaluating the health-related quality of life of the rare disease population in Hong Kong using EQ-5D 3-level

Objectives This study aimed to establish a normative profile of health-related quality of life (HRQOL) of the rare disease (RD) population in Hong Kong (HK) and identify potential predictors. Methods Between March 2020 and October 2020, patients with RD and caregivers were recruited through Rare Disease Hong Kong, the largest RD patient group alliance in HK. HRQOL was derived using the EQ-5D 3-Level with reference to the established HK value set. Utility scores were stratified according to demographics and disease-related information. Multiple linear regression was performed to explore the associations between patient characteristics and HRQOL. Results A total of 286 patients, covering 107 unique RDs, reported a mean utility score of 0.53 (SD 0.36). Thirty patients (10.5%) reported negative utility scores, indicating worse-than-death health states. More problems were recorded in the “usual activities” and “self-care” dimensions. Univariate analyses revealed that neurologic diseases, high out-of-pocket expenditure, home modification, and living in public housing or subdivided flats/units were significantly associated with lower HRQOL. A total of 99 caregivers reported a mean utility score of 0.78 (SD 0.17), which was significantly associated with the utility score of patients they took care of (r = 0.32; P = .001). Conclusions The normative profile of the RD population was established, which revealed lower HRQOL in the RD population than other chronic disease groups and general population in HK. Findings were corroborated by evidence from other cohorts using EQ-5D, combined as part of a meta-analysis. Identifying predictors highlight areas that should be prioritized to improve HRQOL of RD population through clinical and psychosocial dimensions

Broad activation of the Parkin pathway induces synaptic mitochondrial deficits in early tauopathy

Mitochondrial defects are a hallmark of early pathophysiology in Alzheimer’s disease, with pathologically phosphorylated tau reported to induce mitochondrial toxicity. Mitophagy constitutes a key pathway in mitochondrial quality control by which damaged mitochondria are targeted for autophagy. However, few details are known regarding the intersection of mitophagy and pathologies in tauopathy. Here, by applying biochemical and cell biological approaches including time-lapse confocal imaging in live tauopathy neurons, combined with gene rescue experiments via stereotactic injections of adeno-associated virus particles into tauopathy mouse brains, electrophysiological recordings and behavioural tests, we demonstrate for the first time that mitochondrial distribution deficits at presynaptic terminals are an early pathological feature in tauopathy brains. Furthermore, Parkin-mediated mitophagy is extensively activated in tauopathy neurons, which accelerates mitochondrial Rho GTPase 1 (Miro1) turnover and consequently halts Miro1-mediated mitochondrial anterograde movement towards synaptic terminals. As a result, mitochondrial supply at tauopathy synapses is disrupted, impairing synaptic function. Strikingly, increasing Miro1 levels restores the synaptic mitochondrial population by enhancing mitochondrial anterograde movement and thus reverses tauopathy-associated synaptic failure. In tauopathy mouse brains, overexpression of Miro1 markedly elevates synaptic distribution of mitochondria and protects against synaptic damage and neurodegeneration, thereby counteracting impairments in learning and memory as well as synaptic plasticity. Taken together, our study reveals that activation of the Parkin pathway triggers an unexpected effect—depletion of mitochondria from synaptic terminals, a characteristic feature of early tauopathy. We further provide new mechanistic insights into how parkin activation-enhanced Miro1 degradation and impaired mitochondrial anterograde transport drive tauopathy-linked synaptic pathogenesis and establish a foundation for future investigations into new therapeutic strategies to prevent synaptic deterioration in Alzheimer’s disease and other tauopathies

Health-related quality of life from the FALCON phase III randomised trial of fulvestrant 500 mg versus anastrozole for hormone receptor-positive advanced breast cancer

Background The phase III randomised FALCON trial (NCT01602380) demonstrated improved progression-free survival with fulvestrant 500 mg versus anastrozole 1 mg in endocrine therapy-naïve postmenopausal women with hormone receptor-positive (HR+) locally advanced or metastatic breast cancer (LA/MBC). Furthermore, overall health-related quality of life (HRQoL) was maintained and comparable for fulvestrant and anastrozole. Here, we present additional analyses of patient-reported HRQoL outcomes from FALCON. Methods Women with endocrine therapy-naïve HR+ LA/MBC were randomised 1:1 to fulvestrant (days 0, 14, 28, then every 28 d) or anastrozole (daily) until disease progression or discontinuation. HRQoL was assessed by FACT-B questionnaire (TOI and FACT-B total score) at randomisation and every 12 weeks during treatment. HRQoL data post-treatment (with or without progression) were also collected. Results In total, 462 patients were randomised (fulvestrant, n = 230; anastrozole, n = 232). Compliance to FACT-B overall ranged from 60.0 to 97.4%. Mean change from baseline in TOI and FACT-B total score remained broadly stable (approximately ± 3 points to week 132) and was similar between arms during treatment. HRQoL was also maintained in FACT-B subscales. Approximately one-third of patients had improved TOI (≥+6 points) and FACT-B (≥+8 points) total scores from baseline up to week 120 and 132, respectively, of treatment with fulvestrant (ranges 26.4–45.0% and 22.4–35.8%, respectively) and anastrozole (ranges 18.6–32.9%, and 22.7–37.9%, respectively). Conclusions Mean change from baseline in TOI and FACT-B total score was maintained for fulvestrant and anastrozole; similar proportions of patients in both arms had improved TOI and FACT-B total scores

Evaluation of ion exchange processes in drug-eluting embolization beads by use of an improved flow-through elution method.

n improved method for evaluating drug release behaviour of drug-eluting embolization beads (DEBs) was developed utilizing an open-loop flow-through system, in which the beads were packed into an occlusive mass within the system and extracted with a flowing elution medium over time. Glass beads were introduced into the beads mass in order to ensure laminar flow, reduce dead volume and improve reproducibility by compensating for swelling phenomena. The effects of glass bead ratio, elution medium flow rate and ion concentration, DEB size and drug concentration and drug type (doxorubicin and irinotecan) were evaluated using DEB composed of a sulfonate-modified polyvinyl alcohol hydrogel (DC Bead™) as the test article. The rate and amount of drug elution from the packed beads was affected by flow rate, the bead size and initial loading dose. The raw data from the concentration profile analysis provided valuable information to reveal the drug elution behaviour akin to the pharmacokinetic data observed for embolized beads (yielding in vitro Cmax and tmax data) which was complementary to the normal cumulative data obtained. A good correlation with historical reported in vivo data validated the usefulness of the method for predicting in vivo drug elution behaviour

Synthesis and asymmetric hydrogenation of (3E)-1-benzyl-3-[(2-oxopyridin-1(2H)-yl)methylidene]piperidine-2,6-dione

The synthesis of (3E)-1-benzyl-3-[(2-oxopyridin-1(2H)-yl)methylidene]piperidine-2,6-dione 4 from N-benzylglutarimide was achieved in three steps. The asymmetric hydrogenation of 4 gave either the product of partial reduction (10) or full reduction (13), depending on the catalyst which was employed, in high ee in each case. Attempts at asymmetric transfer hydrogenation (ATH) of 4 resulted in formation of a racemic product

Validity and Reliability of the Integrated Palliative Care Outcome Scale in Asian Heart Failure Patients

BACKGROUND: The Integrated Palliative Care Outcome Scale (IPOS) was developed in the United Kingdom for health assessment in advanced illness. OBJECTIVES: To evaluate the validity and reliability of a culturally adapted IPOS (both patient and staff versions) for heart failure (HF). DESIGN/SETTING: We recruited HF patients and staff from a tertiary hospital in Singapore. We collected patient IPOS, New York Heart Association (NYHA) status, Edmonton Symptom Assessment System (ESAS) and Minnesota Living with Heart Failure (MLHF) scores at baseline, and patient IPOS at follow-up. Each baseline patient IPOS was matched with a staff IPOS. MEASUREMENTS: Pearson correlation coefficient (r) between ESAS, MLHF, and patient IPOS was calculated to assess construct validity. The two-sample T-test assessed difference in patient and staff IPOS scores across NYHA status and care settings for known-group validity. Internal consistency of patient and staff IPOS was assessed using Cronbach's alpha (α). Intraclass correlation coefficient (ICC) was used to assess test-retest reliability of patient IPOS and inter-rater reliability between patient and staff IPOS. RESULTS: Ninety-one patients and 12 staff participated. There was strong convergent validity of total patient IPOS with MLHF (r = 0.78) and ESAS (r = 0.81). There were statistically significant differences in total IPOS across care settings (patient-IPOS: 8.05, staff-IPOS 13.61) and NYHA (patient-IPOS: 7.52, staff-IPOS 12.71).There was high internal consistency of total patient (α = 0.83) and staff IPOS (α = 0.88) and high test-retest reliability of patient IPOS (ICC 0.81). Inter-rater reliability (ICC) ranged between 0.82 and 0.91. CONCLUSION: The IPOS was valid and reliable for HF patients in Singapore.publishedVersionPeer reviewe

Predictors of Aged Residential Care Placement in Patients Newly Diagnosed with Dementia at a New Zealand Memory Service

Background: Aged residential care (ARC) is a significant cost of dementia care. However, little is known about the predictors of ARC placement in New Zealand (NZ), which is important for service planning and funding. The aim of this study was to investigate the sociodemographic and clinical characteristics that predict future ARC placement among people who received a new diagnosis of dementia at a NZ memory service. Methods: Routinely collected baseline sociodemographic and clinical data in a memory service from 14/06/13 and 14/12/19 were linked with administrative LTC admission data up to 24/1/2020. Survival analysis was carried out using multivariate Cox regression models to determine significant risk factors and their association with ARC placement. Results: A total of 657 NZ European, Māori and Pacific Islander patients were included in the analyses. There were significant differences by ethnicity including age, living situation, comorbidity and ARC placement. Adjusted analyses showed that risk of ARC placement was increased by older age (HR 1.02 per year, 95%CI:1.00–1.05), moderate dementia (HR 1.45, 95%CI:1.05–1.99), severe dementia (HR 2.25, 95%CI:1.33–3.81), and antipsychotics (HR 1.55, 95%CI:1.04–2.32); while risk was reduced in Māori (HR 0.35, 95%CI:0.18–0.68) and Pacific Islanders (HR 0.32, 95%CI:0.20–0.51). Conclusions: Despite having more severe dementia and higher comorbidity, Māori and Pacific Islanders had reduced risks of ARC placement. There is an urgent need to better understand dementia care issues and to ensure culturally safe and responsive dementia services are accessible by Māori and Pacific Islanders living in the community
