RESUMO
OBJECTIVES: To examine the cost-effectiveness of an enhanced postdischarge home-based care program for stroke survivors compared with usual care. METHODS: This was a trial-based economic evaluation study. One hundred and sixteen patients with ischemic stroke were recruited from neurology units in a Chinese hospital and randomized into intervention (n = 58) or usual care groups (n = 58). The intervention commenced with predischarge planning and transitioned to home follow-up postdischarge. Trained nurse case managers supported by an interdisciplinary team provided comprehensive assessment, individualized goal setting, and skill training to support home-based rehabilitation for intervention group participants. Standard care was provided to usual care group participants. Total cost and quality-adjusted life-years gained at 3-month (T1), 6-month (T2), and 12-month (T3) follow-ups were calculated. The incremental cost-effectiveness ratios between the groups were obtained. RESULTS: The intervention group showed a significant increase in utility compared with the usual care group at T1 (P = .003), T2 (P = .007), and T3 (P < .001). The average total QALY gain from baseline for the intervention group was higher than for the usual care group at all time points. The likelihood of being cost-effective ranged from 61.9% to 67.2% from the provider perspective, and from 59.7% to 66.8% from the societal perspective. CONCLUSIONS: The results showed that the intervention program was cost-effective with significantly higher quality-adjusted life-years for stroke survivors when compared with usual care. It provides economic evidence to support the development of home-based stroke rehabilitation program, especially in the low- and middle-income countries.

BACKGROUND: Interprofessional education (IPE) has the potential to shape students' collaboration perception and interprofessional identity but remains understudied. This study aims to understand the effects of the IPE program as a contextual trigger to promote collaboration perception change and interprofessional identity formation among healthcare professional students. METHODS: Using concurrent triangulation mixed-methods, we examined the relationship between collaboration perception and interprofessional identity change among health profession students (N = 263), and explored their perspectives on how their IPE experiences influenced their perception and identity. Participants completed the Interdisciplinary Education Perception Scale and Extended Professional Identity Scale and responded to open-ended questions before and after the IPE intervention. Pearson's correlation, t-tests, regression (quantitative), and thematic analysis (qualitative) were conducted. RESULTS: Teams with initially lower collaboration perception (M = 3.59) and lower interprofessional identity (M = 3.59) showed a significant increase in collaboration perception (M = 3.76, t = 2.63; p = .02) and interprofessional identity (M = 3.97, t = 4.86; p < .001) after participating in IPE. The positive relationship between collaboration perception and interprofessional identity strengthened after participating in IPE, as evident from the correlation (Time 1: r = .69; p < .001; Time 2: r = .79; p < .001). Furthermore, collaboration perception in Time 1 significantly predicted the variance in interprofessional identity at Time 2 (ß = 0.347, p < .001). Qualitative findings indicated that 85.2% of students expressed that IPE played a role in promoting their interprofessional identity and collaboration attitudes. CONCLUSIONS: Incorporating the IPE program into the curriculum can effectively enhance students' collaboration perception and interprofessional identity, ultimately preparing them for collaborative practice in the healthcare system. By engaging students in interprofessional teamwork, communication, and joint decision-making processes, the IPE program provides a valuable context for students to develop a sense of belonging and commitment to interprofessional collaboration.

BACKGROUND: Elevations in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were reported as adverse events of nirmatrelvir/ritonavir users in the EPIC-HR trial. AIM: To quantify the risk and severity of acute liver injury (ALI) associated with nirmatrelvir/ritonavir use. METHODS: This self-controlled case-series study was conducted using electronic medical records of patients with confirmed diagnosis of SARS-CoV-2 infection between 26th February 2022 and 12th February 2023 in Hong Kong. RESULTS: Among 2 409 848 patients with SARS-CoV-2 infection during the study period, 153 853 were prescribed with nirmatrelvir/ritonavir, of whom 834 (.5%) had incident ALI (moderate: 30.5%; moderate to severe: 18.9%; severe or fatal: 5.8%). Compared with the non-exposure period, risk of ALI increased significantly during the pre-exposure period (IRR = 38.13, 95% CI = 29.29-49.62) and remained elevated during the five-day nirmatrelvir/ritonavir treatment (IRR = 20.75, 95% CI = 17.06-25.25) and during wash-out period (IRR = 16.27, 95% CI = 13.23-20.01). Compared to the pre-exposure period, risk of ALI was not increased during the five-day nirmatrelvir/ritonavir treatment period (IRR = .54, 95% CI = .43-.70). Compared to 5469 non-nirmatrelvir/ritonavir users with incident ALI, nirmatrelvir/ritonavir users had less severe ALI by the severity index (p < .001) and peak INR (1.7 vs. 2.3; p < .001). ALI cases with nirmatrelvir/ritonavir use had lower risk of all-cause death (29.1% vs. 39.1%; OR = .64; p < .001) and no increase in risk of liver decompensation (1.0% vs. 1.3%; OR = .62; p = .230) compared to non-users. CONCLUSION: The risk of ALI associated with nirmatrelvir/ritonavir treatment for COVID-19 was elevated in the pre-exposure period, but not following nirmatrelvir/ritonavir initiation. ALI following nirmatrelvir/ritonavir treatment were mostly mild and less severe than ALI events in non-nirmatrelvir/ritonavir users.

OBJECTIVES: A partnership model in interprofessional education (IPE) is important in promoting a sense of global citizenship while preparing students for cross-sector problem-solving. However, the literature remains scant in providing useful guidance for the development of an IPE programme co-implemented by external partners. In this pioneering study, we describe the processes of forging global partnerships in co-implementing IPE and evaluate the programme in light of the preliminary data available. METHODS: This study is generally quantitative. We collected data from a total of 747 health and social care students from four higher education institutions. We utilized a descriptive narrative format and a quantitative design to present our experiences of running IPE with external partners and performed independent t-tests and analysis of variance to examine pretest and posttest mean differences in students' data. RESULTS: We identified factors in establishing a cross-institutional IPE programme. These factors include complementarity of expertise, mutual benefits, internet connectivity, interactivity of design, and time difference. We found significant pretest-posttest differences in students' readiness for interprofessional learning (teamwork and collaboration, positive professional identity, roles, and responsibilities). We also found a significant decrease in students' social interaction anxiety after the IPE simulation. CONCLUSIONS: The narrative of our experiences described in this manuscript could be considered by higher education institutions seeking to forge meaningful external partnerships in their effort to establish interprofessional global health education.

BACKGROUND: Benefits of intercalation during an undergraduate medical degree are well-recognized. The University of Hong Kong implemented a compulsory Enrichment Year (EY) in its Bachelor of Medicine and Bachelor of Surgery degree programme (MBBS) in 2016. In their third year of study, students could work on an area of interest in any of three programme categories (i) intercalation/ university exchange (IC); (ii) research (RA); (iii) service/ humanitarian work (SH). This study aimed to explore the barriers, enablers, and overall student learning experiences from the first cohort of EY students in order to inform future development of the EY. METHODS: An exploratory sequential mixed-method study in 2019-20. Twenty students were purposively selected to attend three semi-structured focus group interviews. Conventional thematic analysis was employed and results assisted the design of a cross-sectional questionnaire. Sixty-three students completed the questionnaire. ANOVA or chi-square test was used to compare the difference in student's characteristics, barriers, enablers and perspectives on EY between programme categories. Adjusting student's characteristics, logistic regressions were conducted to identify the effect of programme categories on the EY experience. RESULTS: Most students (95% in the questionnaire) agreed that EY was worthwhile and more rewarding than expected. EY was positively regarded for enhancing personal growth and interpersonal relationships. The main barriers were financial difficulties, scholarship issues and insufficient information beforehand. A few students had practical (i.e. accommodation, cultural adaptation) problems. Potential enablers included better financial support, more efficient information exchange and fewer assignments and preparation tasks. Similar barriers were encountered by students across all three categories of EY activities. CONCLUSIONS: Personal growth was the most important benefit of the EY. Barriers were consistent with those identified in the literature except for cultural adaptation, which could be related to Hong Kong's unique historical context. Financial limitation was the most concerning barrier, as it could result in unequal access to educational opportunities. Better and timely access to scholarships and other funding sources need to be considered. TRIAL REGISTRATION: Ethics approval was obtained from the local Institutional Review Board of The University of Hong Kong/Hospital Authority Hong Kong West Cluster (UW 19-585 ).

OBJECTIVE: To examine the cost-effectiveness of a preventive self-care health management program for community-dwelling older adults as compared to usual care. DESIGN/INTERVENTION: A cost-effectiveness analysis was executed alongside a randomised controlled trial. Nurse case managers provided interventions, including holistic assessment, empowerment of self-care, preventive health behaviours and self-efficacy with co-produced care planning, supported by nursing students. The control group received social control calls. PARTICIPANTS/SETTING: Community-dwelling older adults were randomly assigned to the intervention (n = 271) or control (n = 269) group. The intervention was conducted in collaboration with 11 community centres under four non-government organisations in various districts of Hong Kong. MEASUREMENTS: Cost and quality-adjusted life years (QALYs) were collected pre (baseline, 0 months) and post intervention (3 months) and 3 months after completion of the program (6 months). Incremental cost-effectiveness ratios between the groups were calculated, dividing the difference in cost by the difference in QALYs. RESULTS: Analysis showed that the net incremental QALY gain was 0.0014 (3 months) and 0.0033 (6 months) when the intervention group was compared to the control group. The probability of being cost-effective at 6 months was 53.2% and 53.4%, based on the cost-effectiveness thresholds recommended by both the National Institute for Health and Clinical Excellence ($200,000/QALYs) and the World Health Organization (Hong Kong gross domestic product/capita, HK$381,780). CONCLUSIONS: The results provide some evidence to suggest that the addition of a home-based, preventive self-care health management program may have effects on cost outcomes for community-dwelling older adults in Hong Kong.

AIM: To evaluate the long-term cost-effectiveness of a Patient Empowerment Programme (PEP) for type 2 diabetes mellitus (DM) in primary care. MATERIALS AND METHODS: PEP participants were subjects with type 2 DM who enrolled into PEP in addition to enrolment in the Risk Assessment and Management Programme for DM (RAMP-DM) at primary care level. The comparison group was subjects who only enrolled into RAMP-DM without participating in PEP (non-PEP). A cost-effectiveness analysis was conducted using a patient-level simulation model (with fixed-time increments) from a societal perspective. We incorporated the empirical data from a matched cohort of PEP and non-PEP groups to simulate lifetime costs and outcomes for subjects with DM with or without PEP. Incremental cost-effectiveness ratios (ICER) in terms of cost per quality adjusted life year (QALY) gained were calculated. Probabilistic sensitivity analysis was conducted with results presented as a cost-effectiveness acceptability curve. RESULTS: With an assumption that the PEP effect would last for 5 years as shown by the empirical data, the incremental cost per subject was US $197 and the incremental QALYs gained were 0.06 per subject, which resulted in an ICER of US $3290 per QALY gained compared with no PEP across the lifetime. Probabilistic sensitivity analysis showed 66% likelihood that PEP is cost-effective compared with non-PEP when willingness-to-pay for a QALY is ≥US $46 153 (based on per capita GDP 2017). CONCLUSIONS: Based on this carefully measured cost of PEP and its potentially large benefits, PEP could be highly cost-effective from a societal perspective as an adjunct intervention for patients with DM.

BACKGROUND: Studies have shown positive clinical outcomes of specialist palliative care for end-stage heart failure patients, but cost-effectiveness evaluation is lacking. AIM: To examine the cost-effectiveness of a transitional home-based palliative care program for patients with end-stage heart failure patients as compared to the customary palliative care service. DESIGN: A cost-effectiveness analysis was conducted alongside a randomized controlled trial (Trial number: NCT02086305). The costs included pre-program training, intervention, and hospital use. Quality of life was measured using SF-6D. SETTING/PARTICIPANTS: The study took place in three hospitals in Hong Kong. The inclusion criteria were meeting clinical indicators for end-stage heart failure patients including clinician-judged last year of life, discharged to home within the service area, and palliative care referral accepted. A total of 84 subjects (study = 43, control = 41) were recruited. RESULTS: When the study group was compared to the control group, the net incremental quality-adjusted life years gain was 0.0012 (28 days)/0.0077 (84 days) and the net incremental costs per case was -HK$7935 (28 days)/-HK$26,084 (84 days). The probability of being cost-effective was 85% (28 days)/100% (84 days) based on the cost-effectiveness thresholds recommended both by National Institute for Health and Clinical Excellence (£20,000/quality-adjusted life years) and World Health Organization (Hong Kong gross domestic product/capita in 2015, HK$328117). CONCLUSION: Results suggest that a transitional home-based palliative care program is more cost-effective than customary palliative care service. Limitations of the study include small sample size, study confined to one city, clinic consultation costs, and societal costs including patient costs and unpaid care-giving costs were not included.

This study evaluated the short-term cost-effectiveness of the Patient Empowerment Programme (PEP) for diabetes mellitus (DM) in Hong Kong. Propensity score matching was used to select a matched group of PEP and non-PEP subjects. A societal perspective was adopted to estimate the cost of PEP. Outcome measures were the cumulative incidence of all-cause mortality and diabetic complication over a 5-year follow-up period and the number needed to treat (NNT) to avoid 1 event. The incremental cost-effectiveness ratio (ICER) of cost per event avoided was calculated using the PEP cost per subject multiplied by the NNT. The PEP cost per subject from the societal perspective was US$247. There was a significantly lower cumulative incidence of all-cause mortality (2.9% vs 4.6%, P < .001), any DM complication (9.5% vs 10.8%, P = .001) and CVD events (6.8% vs 7.6%, P = .018), in the PEP group. The costs per death from any cause, DM complication or case of CVD avoided were US$14 465, US$19 617 and US$30 796, respectively. The extra amount allocated to managing PEP was small and it appears cost-effective in the short-term as an addition to RAMP.

BACKGROUND: home visits and telephone calls are two often used approaches in transitional care, but their differential economic effects are unknown. OBJECTIVE: to examine the differential economic benefits of home visits with telephone calls and telephone calls only in transitional discharge support. DESIGN: cost-effectiveness analysis conducted alongside a randomised controlled trial (RCT). PARTICIPANTS: patients discharged from medical units randomly assigned to control (control, N = 210), home visits with calls (home, N = 196) and calls only (call, N = 204). METHODS: cost-effectiveness analyses were conducted from the societal perspective comparing monetary benefits and quality-adjusted life years (QALYs) gained. RESULTS: the home arm was less costly but less effective at 28 days and was dominating (less costly and more effective) at 84 days. The call arm was dominating at both 28 and 84 days. The incremental QALY for the home arm was -0.0002/0.0008 (28/84 days), and the call arm was 0.0022/0.0104 (28/84 days). When the three groups were compared, the call arm had a higher probability being cost-effective at 84 days but not at 28 days (home: 53%, call: 35% (28 days) versus home: 22%, call: 73% (84 days)) measuring against the NICE threshold of £20,000. CONCLUSION: the original RCT showed that the bundled intervention involving home visits and calls was more effective than calls only in the reduction of hospital readmissions. This study adds a cost perspective to inform policymakers that both home visits and calls only are cost-effective for transitional care support, but calls only have a higher chance of being cost-effective for a sustained period after intervention.

High-flow nasal cannula (HFNC) is an emerging option for maintaining oxygenation in patients undergoing laryngeal surgery, as an alternative to traditional tracheal ventilation and jet ventilation (JV). However, the data on its safety and efficacy is sparse. This study aims to aggregate the current data and compares the use of HFNC with tracheal intubation and jet ventilation in adult patients undergoing laryngeal surgery. We searched PubMed, MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online), Embase (Excerpta Medica Database), Google Scholar, Cochrane Library, and Web of Science. Both observational studies and prospective comparative studies were included. Risk of bias was appraised with the Cochrane Collaboration Risk of Bias in Non-Randomized Studies - of Interventions (ROBINS-I) or RoB2 tools and the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for case series. Data were extracted and tabulated as a systematic review. Summary statistics were performed. Meta-analyses and trial sequential analyses of the comparative studies were performed. Forty-three studies (14 HFNC, 22 JV, and seven comparative studies) with 8064 patients were included. In the meta-analysis of comparative studies, the duration of surgery was significantly reduced in the THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) group, but the number of desaturations, need for rescue intervention, and peak end-tidal CO2 were significantly increased compared to the conventional ventilation group. The evidence was of moderate certainty and there was no evidence of publication bias. In conclusion, HFNC may be as effective as tracheal intubation in oxygenation during laryngeal surgery in selected adult patients and reduces the duration of surgery but conventional ventilation with tracheal intubation may be safer. The safety of JV was comparable to HFNC.
RESUMO
BACKGROUND: The application of self-determination theory in explaining student achievement has been well-established in various contexts. However, its application to medical education, particularly in interprofessional education (IPE) remains underexplored. Understanding how students' motivation plays a role in students' engagement and achievement is essential to optimize efforts to improve learning and instruction. OBJECTIVE: This two-stage study aims to contextualize the SDT framework to IPE through the adaptation of the Basic Psychological Need Satisfaction to IPE (Study 1) and to demonstrate how SDT can be applied in IPE by examining a model of SDT constructs (Study 2) in predicting outcomes (behavioral engagement, team effectiveness, collective dedication, goal achievement). DESIGN: In Study 1 (n=996), we adapted and validated BPNS-IPE using confirmatory factor analysis and multiple linear regression using data from 996 IPE students (Chinese Medicine, Medicine, Nursing, and Pharmacy). In Study 2 (n=271), we implemented an IPE program where we integrated SDT approaches and examined the relationship of SDT constructs with IPE outcomes using multiple linear regression. RESULTS: Our data supported the three-factor structure (autonomy, competence, and relatedness) of BPNS-IPE, meeting the required model fit. Autonomy predicted team effectiveness (F=51.290, p<.05, R2=.580); competence predicted behavioral engagement (F=55.181, p<.05, R2=.598); while relatedness predicted significantly four IPE outcomes: behavioral engagement (F=55.181, p<.01, R2=.598), team effectiveness (F=51.290, p<.01, R2=.580), collective dedication (F=49.858, p<.01, R2=.573), goal achievement (F=68.713, p<.01, R2=.649). CONCLUSIONS: The SDT motivational framework can be adapted and applied in the IPE context to understand and enhance student motivation in medical education. Potential studies with the use of the scale are provided to guide researchers.

BACKGROUND: Interprofessional education (IPE) has been promoted as a breakthrough in healthcare because of the impact when professionals work as a team. However, despite its inception dating back to the 1960s, its science has taken a long time to advance. There is a need to theorize IPE to cultivate creative insights for a nuanced understanding of IPE. This study aims to propose a research agenda on social interaction by understanding the measurement scales used and guiding researchers to contribute to the discussion of social processes in IPE. METHOD: This quantitative research was undertaken in a cross-institutional IPE involving 925 healthcare students (Medicine, Nursing, Social Work, Chinese Medicine, Pharmacy, Speech Language Pathology, Clinical Psychology, Food and Nutritional Science and Physiotherapy) from two institutions in Hong Kong. Participants completed the Social Interaction Anxiety Scale (SIAS-6) and Social Phobia Scale (SPS-6). We applied a construct validation approach: within-network and between-network validation. We performed confirmatory factors analysis, t-test, analysis of variance and regression analysis. RESULTS: CFA results indicated that current data fit the a priori model providing support to within-network validity [RMSEA=.08, NFI=.959, CFI=.965, IFI=.965, TLI=.955]. The criteria for acceptable fit were met. The scales were invariant between genders, across year levels and disciplines. Results indicated that social interaction anxiety and social phobia negatively predicted behavioural engagement (F = 25.093, p<.001, R2=.065) and positively predicted behavioural disaffection (F = 22.169, p<.001, R2=.057) to IPE, suggesting between-network validity. CONCLUSIONS: Our data provided support for the validity of the scales when used among healthcare students in Hong Kong. SIAS-6 and SPS-6 have sound psychometric properties based on students' data in Hong Kong. We identified quantitative, qualitative and mixed methods research designs to guide researchers in getting involved in the discussion of students' social interactions in IPE.Key MessagesThe Social Anxiety Scale (SIAS-6) and Social Phobia Scale (SPS-6) scales have sound psychometric properties based on the large-scale healthcare students' data in IPE in Hong Kong.Social interaction anxiety and social phobia negatively predicted students' behavioural engagement with IPE and positively predicted behavioural disaffection. The scales are invariant in terms of gender, year level and discipline.Quantitative, qualitative and mixed methods studies are proposed to aid researchers to contribute in healthcare education literature using the SIAS-6 and SPS-6.

BACKGROUND: Readmissions are costly and have implications for quality of care. Studies have been reported to support effects of transitional care programs in reducing hospital readmissions and enhancing clinical outcomes. However, there is a paucity of studies executing full economic evaluation to assess the cost-effectiveness of these transitional care programs. This study is therefore launched to fill this knowledge gap. METHODS: Cost-effectiveness analysis was conducted alongside a randomized controlled trial that examined the effects of a Health-Social Transitional Care Management Program (HSTCMP) for medical patients discharged from an acute regional hospital in Hong Kong. The cost and health outcomes were compared between the patients receiving the HSTCMP and usual care. The total costs comprised the pre-program, program, and healthcare utilization costs. Quality of life was measured with SF-36 and transformed to utility values between 0 and 1. RESULTS: The readmission rates within 28 (control 10.2%, study 4.0%) and 84 days (control 19.4%, study 8.1%) were significantly higher in the control group. Utility values showed no difference between the control and study groups at baseline (p = 0.308). Utility values for the study group were significantly higher than in the control group at 28 (p < 0.001) and 84 days (p = 0.002). The study group also had a significantly higher QALYs gain (p < 0.001) over time at 28 and 84 days when compared with the control group. The intervention had an 89% chance of being cost-effective at the threshold of £20000/QALY. CONCLUSIONS: Previous studies on transitional care focused mainly on clinical outcomes and not too many included cost as an outcome measure. Studies examining the cost-effectiveness of the post-discharge support services are scanty. This study is the first to examine the cost-effectiveness of a transitional care program that used nurse-led services participated by volunteers. Results have shown that a health-social partnership transitional care program is cost-effective in reducing healthcare costs and attaining QALY gains. Economic evaluation helps to inform funders and guide decisions for the effective use of competing healthcare resources.

Store-operated Ca(2+) entry (SOCE) is activated by redistribution of STIM1 into puncta in discrete ER-plasma membrane junctional regions where it interacts with and activates store-operated channels (SOCs). The factors involved in precise targeting of the channels and their retention at these specific microdomains are not yet defined. Here we report that caveolin-1 (Cav1) is a critical plasma membrane scaffold that retains TRPC1 within the regions where STIM1 puncta are localized following store depletion. This enables the interaction of TRPC1 with STIM1 that is required for the activation of TRPC1-SOCE. Silencing Cav1 in human submandibular gland (HSG) cells decreased plasma membrane retention of TRPC1, TRPC1-STIM1 clustering, and consequently reduced TRPC1-SOCE, without altering STIM1 puncta. Importantly, activation of TRPC1-SOCE was associated with an increase in TRPC1-STIM1 and a decrease in TRPC1-Cav1 clustering. Consistent with this, overexpression of Cav1 decreased TRPC1-STIM1 clustering and SOCE, both of which were recovered when STIM1 was expressed at higher levels relative to Cav1. Silencing STIM1 or expression of DeltaERM-STIM1 or STIM1((684)EE(685)) mutant prevented dissociation of TRPC1-Cav1 and activation of TRPC1-SOCE. However expression of TRPC1-((639)KK(640)) with STIM1((684)EE(685)) restored function and the dissociation of TRPC1 from Cav1 in response to store depletion. Further, conditions that promoted TRPC1-STIM1 clustering and TRPC1-SOCE elicited corresponding changes in SOCE-dependent NFkB activation and cell proliferation. Together these data demonstrate that Cav1 is a critical plasma membrane scaffold for inactive TRPC1. We suggest that activation of TRPC1-SOC by STIM1 mediates release of the channel from Cav1.

OBJECTIVES: Interprofessional education (IPE) harnesses the power of teams to facilitate collaborative learning across disciplines. However, prior research has not paid sufficient attention to the role of team-level factors on IPE outcomes, posing a major theoretical and methodological limitation. In response to this, using social interdependence theory (SIT), this study aimed to delineate the independent contributions of both team-level and student-level interprofessional attitudes (teamwork, roles, and responsibilities; patient-centeredness; and community-centeredness) in predicting IPE collaboration outcomes (goal achievement, team effectiveness, and team performance) employing multi-level analysis. METHODS: To test whether interprofessional attitudes at the team and student levels predict IPE collaboration outcomes, conducted multilevel modeling. We used the pretest and posttest data from 323 healthcare students in Hong Kong from Chinese medicine, medicine, nursing, pharmacy, and social work programmes enrolled in the IPE Cancer module. RESULTS: Among the interprofessional attitudes, "teamwork, roles, and responsibilities" was found to be the best predictor of IPE outcomes, both at the student and team levels. Students who recognized the benefits of shared learning had better goal achievement and team effectiveness. Furthermore, teams that emphasized shared learning also had better overall team performance. CONCLUSIONS: Students' attitudes towards teamwork, roles, and responsibilities in interprofessional collaborative practice, both at the student and team levels, are important to attaining positive student- and team-level outcomes. The study contributes to the expansion of existing knowledge in medical education, theoretically, by adopting SIT as a lens through which collaborative learning in healthcare teams can be understood, and methodologically, by applying multi-level approaches and delineating important student- and team-level predictors of IPE outcomes.

OBJECTIVES: Despite the popularity of interprofessional education, the empirical and theoretical development of its scholarship and science is just emerging. This may be caused in part by the non-availability of measures that can be used by researchers in this field. This study aimed to contribute to the psychological theorizing of interprofessional education by uncovering the psychometric properties of Perceived Locus of Causality adapted to Interprofessional Education (PLOC-IPE) in healthcare education and provide a comprehensive guide on how this can be used to advance the IPE research agenda. METHODS: Confirmatory factor analysis (quantitative design) was used to examine the acceptability of psychometric properties of PLOC-IPE. Data were collected through questionnaires administered at two different time points. The participants consisted of 345 students from Chinese Medicine, Clinical Psychology, Medicine, Nursing, Pharmacy, and Social Work from a university in Hong Kong. RESULTS: Based on confirmatory factor analysis, results of within-network construct validity showed good psychometric properties of PLOC-IPE while between-network validity indicated that the scale can predict IPE-related outcomes. Students' intrinsic motivation in IPE positively predicted emotional engagement and negatively predicted emotional disaffection, demonstrating the applicability of the newly validated PLOC-IPE. Amotivation was a negative predictor of emotional engagement and a positive predictor of emotional disaffection. CONCLUSIONS: Findings support the acceptability of PLOC when adapted to IPE. PLOC-IPE obtained acceptable psychometric properties as a measure of students' academic motivation in IPE. It is an adapted scale that can be used to understand self-determined motivation in the context of IPE in health and social care education. A guide on how PLOC-IPE can be a means by which researchers can contribute to the advancement of scholarship of IPE was provided.

BACKGROUND: The effects of workplace second-hand smoke (SHS) on lung function remain uncertain because of a lack of objective measures for SHS exposures. OBJECTIVE: To determine whether an exposure-response association exists between lung function and two different markers of SHS based on indoor fine particulate (PM(2.5)) and urinary cotinine levels in non-smoking catering workers. DESIGN: A cross-sectional study during a 1.5-year exemption of licensed catering premises from smoke-free legislation. Participants 186 non-smoking catering workers aged 18-65 years in Hong Kong were recruited. A declared non-smoking status was accepted in workers with exhaled breath carbon monoxide levels <6 ppm and urinary cotinine levels <100 ng/ml. MAIN OUTCOME MEASURES: Lung function measures of forced expiratory volume in 1s (FEV(1) in litres), forced vital capacity (FVC in litres) and forced expiratory flow as 25-75% of FVC (FEF(25-75) in l/s) were recorded. RESULTS: Indoor fine particulate (PM(2.5)) concentrations were 4.4 times as high in smoking premises (267.9 µg/m(3)) than in non-smoking premises (60.3 µg/m(3)) and were strongly associated with the probability of permitted smoking (R(2)=0.99). Smoking was the dominant source of particulates (R(2)=0.66). Compared with workers exposed to the lowest indoor PM(2.5) stratum (<25 µg/m(3)), lung function was lower in the three higher PM(2.5) strata (25-75, 75-175, >175 µg/m(3)) with FEV(1) -0.072 (95% CI -0.123 to -0.021), -0.078 (95% CI -0.132 to -0.024), -0.101 (95% CI -0.187 to -0.014); FEF(25-75) -0.368 (95% CI -0.660 to -0.077), -0.489 (95% CI -0.799 to -0.179), -0.597 (95% CI -0.943 to -0.251); and FEV(1)/FVC (%) -2.9 (95% CI -4.8 to -1.0), -3.2 (95% CI -5.1 to -1.4) and -4.4 (95% CI -7.4 to -1.3), respectively. Urinary cotinine was associated positively with indoor PM(2.5) but negatively with lung function. Consistently lower values for lung function per unit increase of indoor PM(2.5) were found. CONCLUSION: Lung function is inversely associated with workplace SHS. Workplace exemptions and delays in implementing smoke-free policies and current moves to relax legislation are a major threat to the health of workers.

AIMS/INTRODUCTION: To examine the impact of different levels of financial incentive in terms of fee subsidization on diabetic retinopathy screening in the private primary care setting in Hong Kong. MATERIALS AND METHODS: All general practitioners working in the private sector and registered in two electronic public databases were invited to participate. Consecutive patients with diabetes mellitus were then recruited by the participating practitioners. The recruited participants were randomly allocated to one of three screening groups with different fee levels (HK$0, HK$150 [US$19], HK$300 [US$39]) in a randomized controlled trial. Screening uptake and severity of diabetic retinopathy detected were compared. RESULTS: Out of 1,688 eligible practitioners, 105 participated and invited 402 patients, with 239 initially agreeing to participate (59.5%). After randomization, 78, 75 and 76 participants in the HK$0, HK$150 and HK$300 fee groups, respectively, reconfirmed their participation and were offered screening at the relevant fee. The uptake of screening was 79.5% (62/78), 81.3% (61/75) and 63.2% (48/76), in the HK$0, HK$150 and HK$300 groups, respectively (P < 0.018). Being in the HK$150 fee group was associated with higher uptake of screening than being in the HK$300 fee group (odds ratio 2.31, P = 0.039). No significant difference was found in the prevalence of any diabetic retinopathy (33.9%, 27.9% and 37.5%, P = 0.378) or sight-threatening diabetic retinopathy (4.8%, 8.2% and 16.7%; P = 0.092) among the groups. CONCLUSION: A screening fee of HK$150, representing approximately a half subsidy, appears to be as effective in maximizing uptake as a full subsidy (HK$0) and without deterring those at high risk of diabetic retinopathy from screening.

Basic fibroblast growth factor (bFGF) and its major receptor FGF receptor-1 (FGFR-1) play an important role in the development of the cortex. The mechanisms underlying the mitogenic role of bFGF/FGFR-1 signaling have not been elucidated. Intracellular Ca2+ concentrations ([Ca2+]i) in proliferating cortical neuroepithelial cells are markedly dependent on Ca2+ entry (Maric et al., 2000a). The absence of voltage-dependent Ca2+ entry channels, which emerge later, indicates that other membrane mechanisms regulate [Ca2+]i during proliferation. Canonical transient receptor potential (TRPC) family channels are candidates because they are voltage independent and are expressed during CNS development (Strübing et al., 2003). Here, we investigated the involvement of TRPC1 in bFGF-mediated Ca2+ entry and proliferation of embryonic rat neural stem cells (NSCs). Both TRPC1 and FGFR-1 are expressed in the embryonic rat telencephalon and coimmunoprecipitate. Quantitative fluorescence-activated cell sorting analyses of phenotyped telencephalic dissociates show that approximately 80% of NSCs are TRPC1+, proliferating, and express FGFR-1. Like NSCs profiled ex vivo, NSC-derived progeny proliferating in vitro coexpress TRPC1 and FGFR1. Antisense knock-down of TRPC1 significantly decreases bFGF-mediated proliferation of NSC progeny, reduces the Ca2+ entry component of the Cai2+ response to bFGF without affecting Ca2+ release from intracellular stores or 1-oleoyl-2-acetyl-sn-glycerol-induced Ca2+ entry, and significantly blocks an inward cation current evoked by bFGF in proliferating NSCs. Both Ca2+ influx evoked by bFGF and NSC proliferation are attenuated by Gd3+ and SKF96365 two antagonists of agonist-stimulated Ca2+ entry. Together, these results show that TRPC1 contributes to bFGF/FGFR-1-induced Ca2+ influx, which is involved in self-renewal of embryonic rat NSCs.
