RESUMO

BACKGROUND: Compassion is critical to the provision of high-quality healthcare and is foregrounded internationally as an issue of contemporary concern. Paid care experience prior to nurse training has been suggested as a potential means of improving compassion, which has been characterised by the values and behaviours of care, compassion, competence, communication, courage, and commitment. There is however a dearth of evidence to support the effectiveness of prior care experience as a means of improving compassion in nursing. OBJECTIVE: To explore the impact of paid prior care experience on the values and behaviours of pre-registration nursing students indicated as characterising compassionate care. DESIGN: Longitudinal mixed methods design employing a modified concurrent triangulation strategy, comprising two work packages. Work package 1 was qualitative, and work package 2 adopted a concurrent embedded strategy with a dominant quantitative component. Research is reported in accordance with the Good Reporting of a Mixed Methods Study framework. SETTING(S): Three United Kingdom universities. PARTICIPANTS: Pre-registration nursing students attending one of three universities, and individuals who had previously participated in a Health Education England paid prior care experience pilot. Participant numbers at time point 1 were questionnaires n = 220, telephone interviews n = 10, and focus groups n = 8. METHODS: Work package 1 consisted of longitudinal semi-structured telephone interviews. Work package 2 comprised validated online questionnaires measuring emotional intelligence, compassion satisfaction and fatigue, resilience, psychological empowerment, and career commitment (as proxies of compassionate values and behaviours), and focus groups. Qualitative data were thematically analysed. Quantitative data were analysed via Analysis of Variance in SPSS v 26. RESULTS: Qualitative findings suggest that prior care experience has both positive and negative effects on students' compassionate values and behaviours, however positive effects do not extend to qualification. No statistically significant differences were found in any of the quantitative outcome measures between participants with and without paid prior care experience. A statistically significant increase in compassion fatigue was identified in both groups of participants post-qualification. Paid prior care experience did not prevent participants from experiencing reality shock on becoming a student or on qualification. CONCLUSIONS: There is insufficient evidence of longitudinal beneficial impact to recommend paid prior care experience as an effective intervention to foster nursing students' compassionate values and behaviours. These findings do not support mandating a period of paid care experience as a prerequisite for entry into nurse education. REGISTRATION: N/A.

RESUMO

BACKGROUND: The experience of living with children with CP is dominated by the voice of the mother while others are rarely reported. Incorporation of the voices of other family members is important for a holistic understanding. METHODS: Drawing on the philosophical perspectives of pragmatism, generic qualitative methodology, and Frank's narratives, this article highlights how restitution was constructed by 30 family members. FINDINGS: They constructed restitution by hoping for a cure through either biomedical and/or alternative models of treatment, followed by intransitive and transcendent restitution. DISCUSSION: This appears to be the first time that restitution has been extended to families living with children with chronic illnesses. APPLICATION TO PRACTICE: This would mean that paediatric nursing professionals and other health professionals dealing with family members living with children with CP could attend to their stories in an open and focused manner to honour and validate their stories as well as their experiences.

RESUMO

OBJECTIVES: Compassion in nursing and interventions to support it are of international relevance and concern. Prior care experience as a prerequisite for entry into pre-registration nurse education is suggested as a means of improving compassion. The impact of prior care experience has not been comprehensively reviewed, therefore the potential effectiveness of prior care experience as a means of improving compassion is unknown. The scoping review question was 'What is known about the impact of care experience prior to commencing pre-registration nurse education and training?' The primary objective was to scope and synthesise existing literature relating to the topic and ascertain key themes pertaining to impact. A secondary objective was to appraise literature, to contextualise findings and assess the state and stage of knowledge and research in the area. DESIGN: The review was guided by Arksey and O'Malley's methodological framework and is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews Checklist. DATA SOURCES: Health sciences databases CINAHL, Medline and PubMed. METHODS: Databases were searched in February 2019, updated August 2021. Data (study characteristics, findings, methodological observations) were extracted from papers meeting inclusion criteria (including peer-reviewed empirical papers with English language, electronic full-text available) and findings thematically analysed. RESULTS: Forty-five papers from 14 countries were included. The majority (64.4 %) were published in Europe (31.1 % in the United Kingdom) between 2010 and 2021 (69 %), 60 % from 2013. Four qualitative themes (compassionate care, commitment, competence and communication) describe the impact of prior care experience, which was variable. CONCLUSIONS: Evidence to support the effectiveness of prior care experience as a prerequisite for entry into nurse education to improve compassion, is inconsistent and insufficient. The literature displays methodological limitations and conclusions should be interpreted in light of these caveats. Recommendations are made for future research, to improve quality and comparability.

RESUMO

INTRODUCTION: Puberty experiences of male adolescents can have significant impacts on physical and psychological health outcomes. This qualitative study explored the puberty experiences of young males in Pakistan, as there are limited accounts of what shapes these puberty experiences, especially for adolescent males living in a restrictive culture. METHODS: Twenty-two young Pakistani men (aged 18-21 years) from two urban sites in Karachi participated in individual face-to-face (n=19) and Skype (n=3) interviews. Qualitative thematic analysis was conducted using an inductive approach to identity and examine the patterns emerging from the data. RESULTS: Participants described puberty as a challenging phase for which they were unprepared with a combination of various socio-cultural factors exposing them to negative impacts. As a result, young men expressed feelings of anxiety, embarrassment and isolation. Societal and gender norms around masculinity, sexuality and the roles and responsibilities of young men had a significant impact on how participants experienced puberty. While negative reactions towards puberty were dominant, participants described adopting coping strategies (e.g. social support) to help them deal with negative experiences. CONCLUSIONS: Findings highlight the significance of culturally appropriate puberty education and various facilitating factors that may improve the puberty experiences for future young men. While extending current literature, this study also identifies key factors that could inform the development of health promotion programmes, which may aid adolescent males' puberty transition and positively influence their long-term health, well-being and identity.

RESUMO

BACKGROUND: Schizophrenia is a serious form of mental illness that often requires long term care. Empirical findings indicate that combining a psycho-educational intervention (PEI) with neuroleptic medication to treat schizophrenia is effective. However, there is little information on the therapeutic mechanism of PEIs. METHODS: A qualitative process evaluation was conducted with a purposive sample of people diagnosed with schizophrenia (PDwS, n = 8) and their Primary Caregivers (PCs, n = 9) who had received PEI as a part of an exploratory randomized controlled trial. Semi-structured interviews were conducted to explore potential processes underpinning any observed effect. Thematic analysis was used to analyze and identify prominent patterns in the data. Interviews were conducted between April 2013 and August 2013. RESULTS: Three themes emerged from the qualitative interviews, 'Awareness of schizophrenia', 'Positive impact on health and wellbeing', 'empowerment and enhanced confidence', which described the variety of experiences with the intervention, although most reported that the intervention was acceptable and valued. CONCLUSION: This study identified that individual understanding varied between PDwS and PCs and led to differences in the ways that they used knowledge gained from the PEI in everyday situations. These data support the importance of improving understanding of schizophrenia by PDwS and their PCs to enable them to benefit more fully from medication. TRIAL REGISTRATION: Current Controlled Trials ISRCTN78084871 . Retrospectively registered 28 December 2015.

RESUMO

BACKGROUND: Psycho-educational interventions for people diagnosed with schizophrenia (PDwS) and their primary caregivers appear promising, however, the majority of trials have significant methodological shortcomings. There is little known about the effects of these interventions delivered in a booklet format in resource-poor countries. METHODS: A randomized controlled trial was conducted from September, 2012 to July, 2013 with 121 dyads of PDwS and their primary caregivers. Participants aged 18 years or older with DSM-IV schizophrenia or schizoaffective disorder, and their primary caregivers, from four outpatient mental health clinics in Jordan, were randomly assigned to receive 12 weeks of a booklet form of psycho-education, with follow-up phone calls, and treatment as usual [TAU] (intervention, n = 58), or TAU (control, n = 63). Participants were assessed at baseline, immediately post-intervention (post-treatment1) and at three months follow-up. The primary outcome measure was change in knowledge of schizophrenia. Secondary outcomes for PDwS were psychiatric symptoms and relapse rate, with hospitalization or medication (number of episodes of increasing antipsychotic dosage), and for primary caregivers were burden of care and quality of life. RESULTS: PDwS in the intervention group experienced greater improvement in knowledge scores (4.9 vs -0.5; p <0.001) at post-treatment and (6.5 vs -0.7; p <0.001) at three month-follow-up, greater reduction in symptom severity (-26.1 vs 2.5; p <0.001: -36.2 vs -4.9; p <0.001, at follow-up times respectively. Relapse rate with hospitalization was reduced significantly at both follow-up times in the intervention group (p <0.001), and relapse with medication increased in the intervention group at both follow-up times (p <0.001). Similarly there was a significant improvement in the primary caregivers knowledge score at post-treatment (6.3 vs -0.4; P < 0.001) and three month-follow-up (7.3 vs -0.7; p <0.001). Primary caregivers burden of care was significantly reduced in the intervention group (-6.4 vs 1.5; p <0.001; -9.4 vs 0.8; p <0.001), and their quality of life improved (9.2 vs -1.6; p = 0.01; 17.1 vs -5.3; p <0.001) at post-treatment and three month-follow-up. CONCLUSIONS: Psycho-education and TAU was more effective than TAU alone at improving participants' knowledge and psychological outcomes.

RESUMO

BACKGROUND: Growing numbers of non-medical health professionals are attaining prescribing rights through post-registration non-medical prescribing (NMP) courses in the UK. However, not all implement prescribing post-qualification. This study evaluated the uptake and perceived usefulness of a mentoring scheme for two cohorts of NMP students at the University of Nottingham. The scheme paired students with qualified mentors with whom they had an opportunity to discuss the integration of prescribing theory into practice. METHODS: Mentors were allocated on days 2-5 of the course. Surveys were distributed to students who completed the NMP course [n = 63] and their mentors. Likert-scale and open-ended questions addressed: use, perceived usefulness, and positive and negative aspects of the mentoring scheme. Semi-structured interviews were conducted with both students (n = 6) and mentors (n = 3) to explore their experience of the mentoring scheme in more detail. Students were purposively selected for interview depending on their level of use of the mentoring system. Interviews were analysed using thematic analysis. RESULTS: The response rates were 65.1% (n = 41) and 56.3% (n = 36) for students and mentors respectively. Just over half of students (57.1%) accessed their mentor. Having a sufficient support network was the key reason for not using the scheme. Students found mentors helpful for: moral support (68.2%); contextualising prescribing (71.4%); and helping them to think about implementing prescribing in practice (72.7%). Fewer mentors felt they helped in relation to contextualising (57.9%) or implementing prescribing (31.6%). Less than half the students and mentors surveyed agreed that they received/provided assistance related to the integration of prescribing theory into practice (38.1% and 42.2% respectively) and assistance with assignments (36.3% and 45.5% respectively).Interviews suggested that students found it difficult to focus on implementing prescribing because of the academic demands of their course, which impacted on uptake and use of the mentoring scheme. Students emphasised the importance of being paired with a prescriber who was successfully prescribing. Mentors benefited from sharing and refreshing their academic knowledge. CONCLUSIONS: Students and mentors derived benefits from participation in this scheme. This intervention may be better as a post-qualification support resource when students are ready to consider their future prescribing practice.

RESUMO

BACKGROUND: Schizophrenia is one of the most serious forms of mental illness among people being treated in psychiatric clinics in developing and developed countries. Providing care for people diagnosed with schizophrenia can be stressful for their caregivers. Psycho-educational interventions may improve patients' and primary caregivers' knowledge of schizophrenia and impact positively on patients' physical and psychological outcomes and primary caregivers' burden of care and quality of life. Studies thus far have shown that these interventions may improve patients' and caregivers' outcomes, but the quality of included randomized controlled trials (RCTs) is poor and it is difficult to draw firm conclusions as to the effectiveness of such interventions on patients and primary caregivers' outcomes, hence the current study. METHODS/DESIGN: A randomized controlled trial in four outpatient mental health clinics in Jordan comparing psycho-educational interventions in the form of six booklets every fortnight, with treatment as usual in people diagnosed with schizophrenia and their primary caregivers. The primary outcome for participants is knowledge of Schizophrenia; secondary outcomes for patients are positive and negative symptoms of schizophrenia and relapse rate, while secondary outcomes for primary caregivers are burden of care and quality of life. All measures are assessed at baseline, immediately post-intervention and at three months follow-up. DISCUSSION: This randomized control trial, conducted in Jordan among people living with schizophrenia and their primary caregivers, will assess the effect of psycho-educational interventions on knowledge of Schizophrenia, patients' positive and negative symptoms and quality of life, and caregivers' burden of care. TRIAL REGISTRATION: Current Controlled Trials ISRCTN78084871.

RESUMO

The phosphoinositol-phospholipase C (PLC) family of enzymes consists of a number of isoforms, each of which has different cellular functions. PLCγ1 is primarily linked to tyrosine kinase transduction pathways, whereas PLCδ1 has been associated with a number of regulatory proteins, including those controlling the cell cycle. Recent studies have shown a central role of PLC in cell organisation and in regulating a wide array of cellular responses. It is of importance to define the precise role of each isoform, and how this changes the functional outcome of the cell. Here we investigated differences in PLC isoform levels and activity in relation to differentiation of human and rat vascular smooth muscle cells. Using Western blotting and PLC activity assay, we show that PLCδ1 and PLCγ1 are the predominant isoforms in randomly cycling human vascular smooth muscle cells (HVSMCs). Growth arrest of HVSMCs for seven days of serum deprivation was consistently associated with increases in PLCδ1 and SM α-actin, whereas there were no changes in PLCγ1 immuno-reactivity. Organ culture of rat mesenteric arteries in serum free media (SFM), a model of de-differentiation, led to a loss of contractility as well as a loss of contractile proteins (SM α-actin and calponin) and PLCδ1, and no change in PLCγ1 immuno-reactivity. Taken together, these data indicate that PLCδ1 is the predominant PLC isoform in vascular smooth muscle, and confirm that PLCδ1 expression is affected by conditions that affect the cell cycle, differentiation status and contractile function.

RESUMO

BACKGROUND: Students regard biological science as one of the most difficult components of the nursing curriculum. However, a good understanding of this area is essential for effective nursing practice. The aim of this study was to explore nursing students' perceptions of the usefulness of supplementary biology podcasts for their learning. METHODS: Biological science podcasts (n=9) were made available to first-year nursing students (n=189) as supplementary learning tools. On completion of their first year, students were asked to complete a survey which investigated the frequency of their podcast use, reasons for use and their perception of the usefulness of podcasts as a learning tool. 153 of these students participated in the survey study (80.9%). Two focus groups were conducted with students (n=6) to gain a detailed understanding of student experiences of the usefulness of the podcasts for their learning. RESULTS: Survey data demonstrated that most students (71%) accessed at least one podcast. The majority of students who reported accessing podcasts agreed that they were useful as learning tools (83%), revision aids (83%) and that they helped promote understanding of course materials (72%). Focus group participants discussed how they found podcasts especially useful in terms of revision. Students valued being able to repeatedly access the lecture materials, and appreciated having access to podcasts from a range of lecturers. Focus group members discussed the benefits of live recordings, in terms of valuing the information gleaned from questions asked during the lecture sessions, although there were concerns about the level of background noise in live recordings. Lack of awareness of the availability of podcasts was an issue raised by participants in both the survey component and the focus groups and this negatively impacted on podcast use. CONCLUSIONS: Nursing students found the availability of biology podcasts helpful for their learning. Successful implementation of these tools to support learning requires teaching staff to understand and promote the importance of these tools.

RESUMO

BACKGROUND: The use of anonymous audience response technology (ART) to actively engage students in classroom learning has been evaluated positively across multiple settings. To date, however, there has been no empirical evaluation of the use of individualised ART handsets and formative feedback of ART scores. The present study investigates student perceptions of such a system and the relationship between formative feedback results and exam performance. METHODS: Four successive cohorts of Non-Medical Prescribing students (n=107) had access to the individualised ART system and three of these groups (n=72) completed a questionnaire about their perceptions of using ART. Semi-structured interviews were carried out with a purposive sample of seven students who achieved a range of scores on the formative feedback. Using data from all four cohorts of students, the relationship between mean ART scores and summative pharmacology exam score was examined using a non-parametric correlation. RESULTS: Questionnaire and interview data suggested that the use of ART enhanced the classroom environment, motivated students and promoted learning. Questionnaire data demonstrated that students found the formative feedback helpful for identifying their learning needs (95.6%), guiding their independent study (86.8%), and as a revision tool (88.3%). Interviewees particularly valued the objectivity of the individualised feedback which helped them to self-manage their learning. Interviewees' initial anxiety about revealing their level of pharmacology knowledge to the lecturer and to themselves reduced over time as students focused on the learning benefits associated with the feedback.A significant positive correlation was found between students' formative feedback scores and their summative pharmacology exam scores (Spearman's rho = 0.71, N=107, p<.01). CONCLUSIONS: Despite initial anxiety about the use of individualised ART units, students rated the helpfulness of the individualised handsets and personalised formative feedback highly. The significant correlation between ART response scores and student exam scores suggests that formative feedback can provide students with a useful reference point in terms of their level of exam-readiness.

RESUMO

BACKGROUND: There is growing research on student use of podcasts in academic settings. However, there is little in-depth research focusing on student experience of podcasts, in particular in terms of barriers to, and facilitators of, podcast use and students' perceptions of the usefulness of podcasts as learning tools. This study aimed to explore the experiences of non-medical prescribing students who had access to podcasts of key pharmacology lectures as supplementary learning tools to their existing course materials. METHODS: Semi-structured interviews were carried out with seven non-medical prescribing students (average age = 43 years), all of whom were nurses, who had access to seven podcasts of key pharmacology lectures. These podcasts took the form of downloadable audio lecture recordings available through the virtual learning environment WebCT. Low, medium and high users of the podcasts took part in the interviews in order to access a variety of student experiences. Interview data was analysed using thematic template analysis to identify key themes surrounding student experience of podcast availability, particularly in relation to barriers to and facilitators of podcast use, and students' experiences of podcasts as a learning tool. RESULTS: Students used podcasts for a variety of reasons such as revisiting lectures, preparing for exams, to clarify or revise specific topics and, to a lesser extent, to catch up on a missed lecture. Barriers to podcast use centred mainly around technological issues. Lack of experience of the technology required to access podcasts proved a barrier for some students. A lack of access to suitable technology was also a reported barrier. Family assistance and I.T. assistance from the university helped facilitate students' use of the podcasts. Students found that using podcasts allowed them to have greater control over their learning and to gauge their learning needs, as well as helping them build their understanding of a complex topic. CONCLUSIONS: Students used podcasts for a variety of reasons. Barriers to podcasts use were generally related to technological issues. Students often found that once assistance had been gained regarding these technological issues, they accessed the podcasts more easily. Students felt that access to podcasts added value to their learning materials by allowing them to better manage their learning and build their understanding. Podcasts represent a valuable additional learning tool for this specific group of older students.

RESUMO

Premature delivery remains a serious risk factor in pregnancy, with currently licensed tocolytics unable to offer significant improvement in neonatal outcome. Further understanding of the regulators of uterine contractility is required to enable the development of novel and more effective tocolytic therapies. The transglutaminase family is a class of calcium-dependent, transamidating enzymes, of which tissue transglutaminase 2 is a multifunctional enzyme with roles in cell survival, migration, adhesion, and contractility. The aim of the present study was to investigate the role of this enzyme in regulating the contractility of pregnant human myometrium. Tissue strips from biopsy samples obtained at elective cesarean section were either allowed to contract spontaneously or induced to contract with oxytocin, phenylephrine, or bradykinin. Activity integrals, used to measure contractile activity, were taken following cumulative additions of the reversible, polyamine transglutaminase inhibitors cystamine and mono-dansylcadaverine and the irreversible, site-specific transglutaminase inhibitors N-benzyloxycarbonyl-l-phenylalanyl-6-dimethylsulfonium-5-oxo-L-norleucine and 1,3-dimethyl-2[(oxopropyl)thio]imidazolium. The ability of cystamine and mono-dansylcadaverine to affect oxytocin-mediated calcium mobilization within primary cultured myometrial cells was also measured utilizing a calcium indicator. All inhibitors attenuated myometrial contractions in a concentration-dependent manner independent of the method of contraction stimulus. Similarly cultured myometrial cells preincubated with cystamine and mono-dansylcadaverine displayed an altered calcium response to oxytocin stimulation. Our findings demonstrate a potential role for tissue transglutaminase 2 in regulating uterine contractility in pregnant human myometrium that may be associated with the calcium signaling cascade required for contraction.

RESUMO

BACKGROUND: Non-medical prescribing (NMP) is a six month course for nurses and certain allied health professionals. It is critical that these students develop a good understanding of pharmacology; however, many students are mature learners with little or no formal biological science knowledge and struggle with the pharmacology component. The implications for patient safety are profound, therefore we encourage students not just to memorise enough pharmacology to pass the exam but to be able to integrate it into clinical practice. Audience response technology (ART), such as the KeePad system (KS) has been shown to promote an active approach to learning and provide instant formative feedback. The aim of this project, therefore, was to incorporate and evaluate the use the KS in promoting pharmacology understanding in NMP students. METHODS: Questions were incorporated into eight pharmacology lectures, comprising a mix of basic and clinical pharmacology, using TurningPoint software. Student (n = 33) responses to questions were recorded using the KS software and the percentage of students getting the question incorrect and correct was made immediately available in the lecture in graphical form. Survey data collected from these students investigated student perceptions on the use of the system generally and specifically as a learning tool. More in depth discussion of the usefulness of the KS was derived from a focus group comprising 5 students. RESULTS: 100% of students enjoyed using the KS and felt it promoted their understanding of key concepts; 92% stated that it helped identify their learning needs and 87% agreed that the technology was useful in promoting integration of concepts. The most prevalent theme within feedback was that of identifying their own learning needs. Analysis of data from the focus group generated similar themes, with the addition of improving teaching. Repeated questioning produced a significant increase (p < 0.05) in student knowledge of specific pharmacological concepts. CONCLUSIONS: The use of ART enhanced non-medical prescribing students' experience of pharmacology teaching. Student perceptions were that this system increased their ability to identify learning needs and promoted understanding and integration of concepts. Students also reported that the technology aided exam revision and reduced associated anxiety.

RESUMO

BACKGROUND: Nurses and other health professionals in the U.K. can gain similar prescribing rights to doctors by undertaking a non-medical prescribing course. Non-medical prescribing students must have a thorough understanding of the pharmacology of prescribing to ensure safe practice. Pharmacology education at this level is complicated by the variation in students' prior subject knowledge of, and anxiety about, the subject. The recent advances in technology, particularly the potential for mobile learning, provide increased opportunities for students to familiarise themselves with lecture materials and hence promote understanding. The objective of this study was therefore to evaluate both the subjective (student perception) and objective (student use and exam results) usefulness of podcasts of pharmacology lectures which were provided as an extra learning tool to two cohorts (n = 69) of non-medical prescribing students. METHODS: The podcasts were made available to students through the virtual learning environment WebCT. Use of podcasts by two successive cohorts of nurse prescribing students (n = 69) was tracked through WebCT. Survey data, which was collected from 44 of these students, investigated patterns of/reasons for podcast use and perceived usefulness of podcasts as a learning tool. Of these 69 students, 64 completed the pharmacology exam. In order to examine any impact of podcasts on student knowledge, their exam results were compared with those of two historical cohorts who did not have access to podcasts (n = 70). RESULTS: WebCT tracking showed that 91% of students accessed at least one podcast. 93% of students used the podcasts to revisit a lecture, 85% used podcasts for revision, and 61% used the podcasts when they had a specific question. Only 22% used the podcasts because they had missed a pharmacology session. Most students (81%) generally listened to the entire podcast rather than specific sections and most (73%) used them while referring to their lecture handouts. The majority of students found the podcasts helpful as a learning tool, as a revision aid and in promoting their understanding of the subject. Evaluation of the range of marks obtained, mode mark and mean mark suggested improved knowledge in students with access to podcasts compared to historical cohorts of students who did not have access to pharmacology podcasts. CONCLUSIONS: The results of this study suggest that non-medical prescribing students utilised podcasts of pharmacology lectures, and have found the availability of these podcasts helpful for their learning. Exam results indicate that the availability of podcasts was also associated with improved exam performance.

RESUMO

BACKGROUND: Problem-based learning is recognised as promoting integration of knowledge and fostering a deeper approach to life-long learning, but is associated with significant resource implications. In order to encourage second year undergraduate medical students to integrate their pharmacological knowledge in a professionally relevant clinical context, with limited staff resources, we developed a novel clustered PBL approach. This paper utilises preliminary data from both the facilitator and student viewpoint to determine whether the use of this novel methodology is feasible with large groups of students. METHODS: Students were divided into 16 groups (20-21 students/group) and were allocated a PBL facilitator. Each group was then divided into seven subgroups, or clusters, of 2 or 3 students wh each cluster being allocated a specific case. Each cluster was then provided with more detailed clinical information and studied an individual and distinct case-study. An electronic questionnaire was used to evaluate both student and facilitator perception of this clustered PBL format, with each being asked to rate the content, structure, facilitator effectiveness, and their personal view of the wider learning experience. RESULTS: Despite initial misgivings, facilitators managed this more complex clustered PBL methodology effectively within the time restraints and reported that they enjoyed the process. They felt that the cases effectively illustrated medical concepts and fitted and reinforced the students' pharmacological knowledge, but were less convinced that the scenario motivated students to use additional resources or stimulated their interest in pharmacology. Student feedback was broadly similar to that of the facilitators; although they were more positive about the scenario stimulating the use of additional resources and an interest in pharmacology. CONCLUSION: This clustered PBL methodology can be successfully used with larger groups of students. The key to success lies with challenging and well situated clinically relevant cases together with enthusiastic facilitators. Facilitator enjoyment of the PBL process may be related to adequate training and previous PBL experience, rather than academic background. The smaller number of facilitators required using this clustered PBL approach allows for facilitators with 'a belief in the philosophy of PBL' to volunteer which would again impact on the success of the process.

RESUMO

BACKGROUND: The shift away from a biological science to a social science model of nursing care has resulted in a reduction in pharmacology knowledge and understanding in pre-registration nursing students. This has a significant impact on nurse prescribing training where pharmacology is a critical component of the course from a patient safety perspective. METHODS: Reusable learning objects (RLOs) are electronic resources based on a single learning objective which use high quality graphics and audio to help engagement with the material and to facilitate learning. This study used questionnaire data from three successive cohorts of nurse prescribing students (n = 84) to evaluate the use of RLOs focussed around pharmacology concepts to promote the understanding of these concepts in students. A small number of students (n = 10) were followed up by telephone interview one year after qualification to gain further insight into students' perceptions of the value of RLOs as an educational tool. RESULTS: Students' perceptions of their own understanding of pharmacology concepts increased substantially following the introduction of RLOs to supplement the pharmacology component of the course. Student evaluation of the RLOs themselves was extremely positive with a number of students continuing to access these tools post-qualification. CONCLUSION: The use of RLOs to support the pharmacology component of nurse prescribing courses successfully resulted in a perceived increase in pharmacology understanding, with some students directly implicating these educational tools in developing confidence in their own prescribing abilities.

RESUMO

Vascular smooth muscle cell (VSMC) chemotaxis is fundamental to atherosclerosis and intimal hyperplasia. An increase in intracellular Ca2+ [Ca2+]i is an important signal in chemotaxis, but the role of L-type calcium channels (CaV1.2) in this response in human vascular smooth muscle cells (hVSMC) has not been examined. hVSMC were grown from explant cultures of saphenous vein. Confluent hVSMC at passage 3 were studied after culture in medium containing 15% foetal calf serum (FCS) (randomly cycling) or following serum deprivation for up to 7 days. Smooth muscle alpha-actin was measured by immunoblotting and immunofluorescence microscopy. [Ca2+]i was measured using fura 2 fluorimetry. Chemotaxis was measured using a modified Boyden chamber technique and cell attachment to gelatin-coated plates was also quantified. The number and affinity of dihydropyridine-binding sites was assessed using [5-methyl-3H]PN 200-110 binding. In randomly cycling cells, the calcium channel agonist, Bay K 8644a and 100 mM KCl did not affect [Ca2+]i. In addition, the rise in [Ca2+]i induced by platelet-derived growth factor-BB (PDGF) was unaffected by the CaV1.2 antagonists, amlodipine and verapamil. In randomly cycling cells amlodipine did not affect PDGF-induced migration. In serum-deprived cells, smooth muscle alpha-actin was increased and Bay K 8644a and 100 mM KCl increased [Ca2+]i. PDGF-induced rises in [Ca2+]i were also inhibited by amlodipine and verapamil. The ability of Bay K 8644a to increase [Ca2+]i and verapamil to inhibit PDGF-induced rises in [Ca2+]i was evident within 3 days after serum withdrawal. In serum-deprived hVSMC Bay K 8644a induced chemotaxis and amlodipine inhibited PDGF-induced migration. Cell attachment in the presence of PDGF was unaffected by amlodipine in either randomly cycling or serum-deprived hVSMC. Serum withdrawal was associated with a decrease in the maximum number of dihydropyridine-binding sites (B(max)) and a decrease in affinity (K(D)). Serum deprivation of hVSMC results in increased expression of smooth muscle alpha-actin, a marker of more differentiated status, and increased [Ca2+]i responses and chemotaxis mediated by CaV1.2. These observations may have important implications for understanding the therapeutic benefits of calcium channel antagonists in cardiovascular disease.

RESUMO

The class 1(A) phosphatidylinositol 3-kinase enzymes consist of a number of heterodimeric complexes of regulatory and catalytic subunits and have been implicated in a number of cellular responses. While platelet-derived growth factor (PDGF)-induced chemotaxis of human vascular smooth muscle cells (HVSMC) is inhibited by both wortmannin and LY294002, DNA synthesis is only inhibited by LY294002. Serum-induced DNA synthesis however is inhibited by LY294002, wortmannin and rapamycin. Similarly PDGF-induced protein kinase B (PKB) activation is inhibited by LY294002 but not by wortmannin or rapamycin. In conclusion PDGF-induced DNA synthesis appears to occur through a phosphatidylinositol 3-kinase (PI3-K)-dependent, but wortmannin-insensitive, PKB/Akt pathway.

RESUMO

Thrombospondin-1 is a large matricellular protein that acts as a pleiotropic growth factor for human vascular smooth muscle cells, and may play a role in the progression of vascular disease. Although we have previously demonstrated the dependence of both thrombospondin-1-stimulated cell chemotaxis and proliferation on tyrosine kinases, the receptor mechanisms involved remain obscure. This investigation aims to determine the nature of the receptor(s) involved in the cellular responses to thrombospondin-1. Cellular signals were identified by western blotting following cell stimulation, while cellular responses were assessed by measuring DNA synthesis and chemotaxis. These data demonstrate that thrombospondin-1-induced cell chemotaxis can be inhibited by a peptide containing the Arg-Gly-Asp motif, a function-blocking alpha(v)beta(3) antibody, a function-blocking integrin-associated protein (IAP) antibody and pertussis toxin, while thrombospondin-1-stimulated DNA synthesis is inhibited by a function-blocking alpha(3)beta(1) antibody. Similarly the Arg-Gly-Asp-containing peptide inhibits tyrosine phosphorylation of focal adhesion kinase and the p85 regulatory subunit of phosphatidylinositol 3-kinase, but does not significantly affect tyrosine phosphorylation, or activation, of extracellular-regulated kinase. These data suggest that soluble thrombospondin-1 interacts with human vascular smooth muscle cells via two independent and separable receptor-binding sites, to differentially stimulate cell chemotaxis and DNA synthesis.
