RESUMEN

With little understandings on the loneliness of older adults in residential care homes structured by social contact restrictions, the provision of person-centered care was jeopardized during the pandemic. This study employed hermeneutic phenomenology to explore the lived experiences of loneliness of this population during a 5-month period of the COVID-19 pandemic. We conducted unstructured face-to-face interviews with 15 older adults living in seven residential care homes. Thematic analysis was guided by Van Manen's approach. The essence of loneliness was uncovered as "A deprived sense of self-significance in a familiar world contributes to older adult's disconnection with prior commitments." A sub-theme "From collapse to dissolution of self-understanding" revealed how COVID-19 structured their loneliness. Another sub-theme, "Restoring meanings by establishing connections with entities" illustrated the ways to mitigate loneliness during the pandemic. Activities fostering alternative self-interpretation are important to protect older adults against loneliness.

RESUMEN

BACKGROUND: Global societal changes, such as increasing longevity and a shortage of family caregivers, have given rise to a popular worldwide trend of employing live-in migrant care workers (MCWs) to provide homecare for older people. However, the emotional labor and morality inherent in their interactions with older people are largely unknown. The aim of the present study is to understand the corporeal experiences of live-in migrant care workers in the delivery of emotional labor as seen in their interactions with older people by: (1) describing the ways by which they manage emotional displays with older people; and (2) exploring their morality as enacted through emotional labor. METHODS: We performed a secondary analysis drawing on feminist phenomenology to thematically analyze data from interviews with 11 female MCWs. Follow-up interviews were conducted with 10 participants. The participants had two to 15 years of experience in caring for older people in their homes in Hong Kong. RESULTS: Performing emotional labor by suppressing and inducing emotions is morally demanding for live-in MCWs, who experience socio-culturally oppressive relationships. However, developing genuine emotions in their relationships with older people prompted the MCWs to protect the interests of older people. Through demonstrating both fake and genuine emotions, emotional labor was a tactic that live-in MCWs demonstrated to interact morally with older people. CONCLUSIONS: Emotional labor allowed live-in MCWs to avoid conflict with older people, and to further protect their own welfare and that of others. This study highlights the significance of empowering live-in MCWs by training them in ways that will help them to adapt to working conditions where they will encounter diverse customs and older people who will develop an increasing dependence on them. Thus, there is a need to develop culturally appropriate interventions to empower live-in MCWs to deliver emotional labor in a moral manner.

RESUMEN

AIMS: (a) To explore the meanings of master's education in the professionalization of nursing; and (b) to describe the core attributes that nurses gained through master's study. DESIGN: Narrative inquiry. METHODS: From June 2017 to June 2018, unstructured interviews were conducted with 12 master-prepared nurses at advanced nursing position with minimum 5 years of postregistration experience. Collaborative thematic narrative analysis was conducted on verbatim transcripts. Members checking, peer validation and audience validation assured verisimilitude and utility. RESULTS: There was a need to fit one's own assertion for professional growth in nursing career structure. Master's study equipped nurses with specialty skills and knowledge with enhanced reflexivity, which nurtured morality, problem-solving ability and capacity to collaborate inter-professionally. Master-prepared nurses demonstrated effective clinical leadership through acting as change agents. CONCLUSIONS: Master's level education and master-prepared nurses are instrumental to the professionalization of nursing by expanding the roles of nurses. Nursing career mentoring will maximize nurses' agency in healthcare system. Developing innovative inter-professional pedagogy will nurture the reflexivity of master-prepared nurses.

RESUMEN

AIMS: This article discusses the ways researchers may become open to manifold interpretations of lived experience through thematic analysis that follows the tradition of hermeneutic phenomenology. BACKGROUND: Martin Heidegger's thinking about historical contexts of understandings and the notions of 'aletheia' and 'techne' disclose what he called meaning of lived experience, as the 'unchanging Being of changing beings'. While these notions remain central to hermeneutic phenomenological research, novice phenomenologists usually face the problem of how to incorporate these philosophical tenets into thematic analysis. DESIGN: Discussion paper. DATA SOURCES: This discussion paper is based on our experiences of hermeneutic analysis supported by the writings of Heidegger. Literature reviewed for this paper ranges from 1927 - 2014. We draw on data from a study of foreign domestic helpers in Hong Kong to demonstrate how 'dwelling' in the language of participants' 'ek-sistence' supported us in a process of thematic analysis. Data were collected from December 2013 - February 2016. IMPLICATIONS FOR NURSING: Nurses doing hermeneutic phenomenology have to develop self-awareness of one's own 'taken-for-granted' thinking to disclose the unspoken meanings hidden in the language of participants. Understanding the philosophical tenets of hermeneutic phenomenology allows nurses to preserve possibilities of interpretations in thinking. In so doing, methods of thematic analysis can uncover and present the structure of the meaning of lived experience. CONCLUSION: We provide our readers with vicarious experience of how to begin cultivating thinking that is aligned with hermeneutic phenomenological philosophical tenets to conduct thematic analysis.

RESUMEN

AIM: To report a meta-ethnography of qualitative research studies exploring the acculturation and socialization experiences of migrant care workers. BACKGROUND: Migrant care workers are increasingly participating in health and social care in developed countries. There is a need to understand this increasingly socioculturally diversified workforce. DATA SOURCES: A comprehensive search through 12 databases and a manual search of journals related to transculture for studies on socialization and acculturation experiences (published 1993-2013) was completed. The inclusion criteria were peer-reviewed studies on the acculturation or socialization experiences of migrant care workers published in English in any country, using a qualitative or mixed-methods approach. DESIGN AND REVIEW METHODS: This meta-ethnography employed the seven-phase Noblit and Hare method with reciprocal translation, refutational synthesis and lines-of-argument to synthesize qualitative studies. RESULTS: Three main themes were identified: (a) schema for the migration dream: optimism; (b) the reality of the migration dream: so close, yet so far; and (c) resilience: from chaos to order. A general framework of motivated psychosocial and behavioural adaptation was proposed. This meta-ethnography also revealed the vulnerabilities of migrant nurses in the process of acculturation and socialization. CONCLUSIONS: The general framework of behavioural and psychosocial adaptation revealed factors that impede and facilitate behavioural and psychosocial changes. Strategies to enrich external and internal resources should be targeted at encouraging multiculturalism and at improving the psychosocial resources of migrant care workers. It is suggested that research investigating the prominence of nursing vulnerabilities be conducted.

RESUMEN

The synthesis and structure-activity relationship of decahydroisoquinoline derivatives with various benzoic acid substitutions as GluK1 antagonists are described. Potent and selective antagonists were selected for a tailored prodrug approach in order to facilitate the evaluation of the new compounds in pain models after oral administration. Several diester prodrugs allowed for acceptable amino acid exposure and moderate efficacy in vivo.

RESUMEN

We have explored the decahydroisoquinoline scaffold, bearing a phenyl tetrazole, as GluK1 antagonists with potential as oral analgesics. We have established the optimal linker atom between decahydroisoquinoline and phenyl rings and demonstrated an improvement of both the affinity for the GluK1 receptor and the selectivity against the related GluA2 receptor with proper phenyl substitution. In this Letter, we also disclose in vivo data that led to the discovery of LY545694·HCl, a compound with oral efficacy in two persistent pain models.

RESUMEN

PURPOSE: To explore older adults' perceived relationship quality with migrant domestic workers (MDWs) and examine the correlation between older adult/MDW (O-M) relationship quality and loneliness of community-dwelling older adults. MATERIALS AND METHODS: In this cross-sectional study, older adults living with MDWs were conveniently recruited from neighbourhood elderly centers in Hong Kong. Loneliness and O-M relationship quality were assessed by the 6-item De Jong Gierveld Loneliness Scale and the mutuality scale, respectively. Older adults' demographic and functional characteristics, and MDW's nationality, spoken language and years of service in the dyad were also collected. Hierarchical multiple regression analyses were conducted to examine the contributions of 1) demographic variables and functional status, 2) MDW characteristics, 3) perceived social network and 4) perceived O-M relationship quality on loneliness. RESULTS: The 178 participants [mean age 83.44 (SD 7.05 years); 155 (87.1%) women and 23 men (22.9%)] were socially lonely (1.07 ± 1.15) and close to being lonely overall (1.90 ± 1.68), and emotionally (0.84 ± 0.97). The mean O-M relationship quality was poor (1.42 ± 0.79), which was significantly correlated with overall (ß= -0.33, 95% CI: -0.65 to -0.01, P value = 0.045), and social (ß= -0.24, 95% CI: -0.46 to -0.01, P value = 0.04) loneliness, but not significantly correlated to emotional loneliness. CONCLUSION: Better perceived O-M relationship quality is correlated with a lower level of loneliness among older adults. Strategies to improve O-M relationship quality may alleviate loneliness among older adults.

RESUMEN

AIMS: To design clinical guidelines on timing for replacing peripheral intravenous catheters, in an attempt to decrease complications and lower related expenditures. BACKGROUND: Intravenous therapy is a common intervention for patients in hospitals and some other clinical settings. However, the currently available international and local guidelines have come under criticism. There is a need to develop evidence-based guidelines to benefit patients as well as to save on the resources of healthcare systems. DESIGN: A discursive paper. METHODS: The evidence-based health care of Dawes et al. (BioMed Central Medical Education 5, 2005, 1) was adopted to guide the development of this guideline. Cochrane Library Database was searched with four keywords: (1) Intravenous, (2) Infusion, (3) Infection, and (4) Timing, which identified one systematic review. Guideline on timing for replacing peripheral intravenous catheters was proposed based on the systematic review. Further recommendation for application in clinical settings and quality management are given. An algorithm on the replacement of peripheral intravenous catheters was included. CONCLUSION: Clinically indicated replacement was suggested over routine replacement because the former results in lower healthcare expenditures without involving any extra risks of complications. RELEVANCE TO CLINICAL PRACTICE: These guidelines are simple and easy to follow in a clinical environment. An algorithm is given to enhance the usage of these guidelines by clinicians.

RESUMEN

Developments in the molecular biology and pharmacology of GLU(K5), a subtype of the kainate class of ionotropic glutamate receptors, have enabled insights into the roles of this subunit in synaptic transmission and plasticity. However, little is known about the possible functions of GLU(K5)-containing kainate receptors in pathological conditions. We report here that, in hippocampal slices, selective antagonists of GLU(K5)-containing kainate receptors prevented development of epileptiform activity--evoked by the muscarinic agonist, pilocarpine--and inhibited the activity when it was pre-established. In conscious rats, these GLU(K5) antagonists prevented and interrupted limbic seizures induced by intra-hippocampal pilocarpine perfusion, and attenuated accompanying rises in extracellular L-glutamate and GABA. This anticonvulsant activity occurred without overt side effects. GLU(K5) antagonism also prevented epileptiform activity induced by electrical stimulation, both in vitro and in vivo. Therefore, we propose that subtype-selective GLU(K5) kainate receptor antagonists offer a potential new therapy for epilepsy.

RESUMEN

We examine the lived experiences of foreign domestic helpers (FDH) working with community-dwelling older people in Hong Kong. Unstructured interviews were conducted with 11 female FDHs, and thematically analyzed. The theme inescapable functioning commodity represented the embodied commodification of FDHs to be functional for older people in home care. Another theme, destined reciprocity of companionship, highlighted the FDHs' capacity to commit to home care and be concerned about older people. The waxing and waning of the possibilities of commodified companionship indicated the intermittent capacity of FDHs to find meaning in their care, in which performative nature for functional purposes and emotional engagement took turns to be the foci in migrant home care. This study addresses the transition of FDHs from task-oriented relation to companions of older people through care work. Discussion draws on the development of a kin-like relationship between FDHs and older people with emotional reciprocity grounded in moral values.

RESUMEN

Amino diacid 3, a highly selective competitive GluR5 kainate receptor antagonist, exhibited high GluR5 receptor affinity and selectivity over other glutamate receptors. Its diethyl ester prodrug 4 was orally active in two models of migraine: the neurogenic dural plasma protein extravasation model and the nucleus caudalis c-fos expression model. These data suggest that a GluR5 kainate receptor antagonist might be an efficacious antimigraine therapy with a novel mechanism of action.

RESUMEN

The synthesis and structure-activity relationship (SAR) of novel and highly potent positive allosteric modulators of AMPA receptors, 3-biphenyl-4-yl-4-cyano-5-ethyl-1-methyl-1H-pyrrole-2-carboxylic acid, are described. These studies indicated that higher potency was achieved with ortho substitution of the distal (D) phenyl of the 3-biphenyl ring and resulted in the discovery of a potent pyrrole LY2059346 (23q), that was selected for further evaluation in in vitro native tissue assays and in vivo experiments.

RESUMEN

The excitatory neurotransmitter glutamate has been implicated in both migraine and persistent pain. The identification of the kainate receptor GLU(K5) in dorsal root ganglia, the dorsal horn, and trigeminal ganglia makes it a target of interest for these indications. We examined the in vitro and in vivo pharmacology of the competitive GLU(K5)-selective kainate receptor antagonist LY466195 [(3S,4aR,6S,8aR)-6-[[(2S)-2-carboxy-4,4-difluoro-1-pyrrolidinyl]-methyl]decahydro-3-isoquinolinecarboxylic acid)], the most potent GLU(K5) antagonist described to date. Comparisons were made to the competitive GLU(K5)/alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor antagonist LY293558 [(3S,4aR,6R,8aR)-6-[2-(1(2)H-tetrazole-5-yl)ethyl]-decahydroisoquinoline-3-carboxylic acid], other decahydroisoquinoline GLU(K5) receptor antagonists, and the noncompetitive AMPA receptor antagonist LY300168 [1-(4-aminophenyl)-4-methyl-7,8-methylenedioxy-5H-2,3-benzodi-azepine]. When characterized electrophysiologically in rat dorsal root ganglion neurons, LY466195 antagonized kainate (30 microM)-induced currents with an IC50 value of 0.045 +/- 0.011 microM. In HEK293 cells transfected with GLU(K5), GLU(K2)/GLU(K5), or GLU(K5)/GLU(K6) receptors, LY466195 produced IC50 values of 0.08 +/- 0.02, 0.34 +/- 0.17, and 0.07 +/- 0.02 microM, respectively. LY466195 was efficacious in a dural plasma protein extravasation (PPE) model of migraine with an ID100 value of 100 microg/kg i.v. LY466195 was also efficacious in the c-fos migraine model, with a dose of 1 microg/kg i.v. significantly reducing the number of Fos-positive cells in the rat nucleus caudalis after electrical stimulation of the trigeminal ganglion. Furthermore, LY466195 showed no contractile activity in the rabbit saphenous vein in vitro. The diethyl ester prodrug of LY466195 was also efficacious in the same PPE and c-fos models after oral administration at doses of 10 and 100 microg/kg, respectively while having no N-methyl-D-aspartate antagonist-like behavioral effects at oral doses up to 100 mg/kg.
