RESUMO

Background: Since boosting stem cell resilience in stressful environments is critical for the therapeutic efficacy of stem cell-based transplantations in liver disease, this study aimed to establish the efficacy of a transient plasmid-based preconditioning strategy for boosting the capability of mesenchymal stromal cells (MSCs) for anti-inflammation/antioxidant defenses and paracrine actions in recipient hepatocytes. Methods: Human adipose mesenchymal stem cells (hADMSCs) were subjected to transfer, either with or without the nuclear factor erythroid 2-related factor 2 (Nrf2)/Dickkopf1 (DKK1) genes, followed by exposure to TNF-α/H2O2. Mouse models were subjected to acute chronic liver failure (ACLF) and subsequently injected with either transfected or untransfected MSCs. These hADMSCs and ACLF mouse models were used to investigate the interaction between Nrf2/DKK1 and the hepatocyte receptor cytoskeleton-associated protein 4 (CKAP4). Results: Activation of Nrf2 and DKK1 enhanced the anti-stress capacity of MSCs in vitro. In a murine model of ACLF, transient co-overexpression of Nrf2 and DKK1 via plasmid transfection improved MSC resilience against inflammatory and oxidative assaults, boosted MSC transplantation efficacy, and promoted recipient liver regeneration due to a shift from the activation of the anti-regenerative IFN-γ/STAT1 pathway to the pro-regenerative IL-6/STAT3 pathway in the liver. Importantly, the therapeutic benefits of MSC transplantation were nullified when the receptor CKAP4, which interacts with DKK1, was specifically removed from recipient hepatocytes. However, the removal of the another receptor low-density lipoprotein receptor-related protein 6 (LRP6) had no impact on the effectiveness of MSC transplantation. Moreover, in long-term observations, no tumorigenicity was detected in mice following transplantation of transiently preconditioned MSCs. Conclusions: Co-stimulation with Nrf2/DKK1 safely improved the efficacy of human MSC-based therapies in murine models of ACLF through CKAP4-dependent paracrine mechanisms.

RESUMO

Difficulty in visualizing anatomical structures has been identified as a challenge in anatomy learning and the emergence of three-dimensional printed models (3DPMs) offers a potential solution. This study evaluated the effectiveness of 3DPMs for learning the arterial supply of the head and neck region. One hundred eighty-four undergraduate medical students were randomly assigned to one of four learning modalities including wet specimen, digital model, 3DPM, and textbook image. Posttest scores indicated that all four modalities supported participants' knowledge acquisition, most significantly in the wet specimen group. While the participants rated 3DPMs lower for helping correct identification of structures than wet specimens, they praised 3DPMs for their ability to demonstrate topographical relationships between the arterial supply and adjacent structures. The data further suggested that the biggest limitation of the 3DPMs was their simplicity, thus making it more difficult for users to recognize the equivalent structures on the wet specimens. It was concluded that future designs of 3DPMs will need to consider the balance between the ease of visualization of anatomical structures and the degree of complexity required for successful transfer of learning. Overall, this study presented some conflicting evidence of the favorable outcomes of 3DPMs reported in other similar studies. While effective for anatomy learning as a standalone modality, educators must identify the position 3DPM models hold relative to other modalities in the continuum of undergraduate anatomy education in order to maximize their advantages for students.

RESUMO

This article investigates the level of anatomical knowledge of the Hong Kong public and uses the data to help suggest public engagement activities and health campaigns to raise health literacy in the general population. In the annual public engagement event organized by the University of Hong Kong, 250 attendees took a survey assessing basic anatomical knowledge by putting organs/structures in their correct positions. Description analysis, correlation analysis, independent sample t-test, and one-way ANOVA analysis were conducted by SPSS 27.0. Overall, a mean score of 6.5 out of 20 was achieved. Differences between various demographic parameters were analyzed, and the results showed that better performance on the survey was associated with younger age, higher educational levels, and having healthcare experience. There was also a statistically significant difference in correctly positioning the thyroid between males and females. Interestingly, some misconceptions were thought to arise from the bespoke use of the Chinese language in the survey. The data reflected room for improvement in the level of anatomical knowledge among the public, notably in the older age groups. This was attributed partially to a lack of public outreach initiatives and established anatomy-focused programs, which has restricted public exposure to anatomical knowledge and hindered the development of anatomical sciences in Hong Kong. In conclusion, the knowledge of the public on the human body needs to be improved and possible solutions to improve public awareness of health were raised.

RESUMO

The mechanisms underlying autophagic defects in nonalcoholic steatohepatitis (NASH) remain largely unknown. We aimed to elucidate the roles of hepatic cyclooxygenase 1 (COX1) in autophagy and the pathogenesis of diet-induced steatohepatitis in mice. Human nonalcoholic fatty liver disease (NAFLD) liver samples were used to examine the protein expression of COX1 and the level of autophagy. Cox1Δhepa mice and their wildtype littermates were generated and fed with 3 different NASH models. We found that hepatic COX1 expression was increased in patients with NASH and diet-induced NASH mice models accompanied by impaired autophagy. COX1 was required for basal autophagy in hepatocytes and liver specific COX1 deletion exacerbated steatohepatitis by inhibiting autophagy. Mechanistically, COX1 directly interacted with WD repeat domain, phosphoinositide interacting 2 (WIPI2), which was crucial for autophagosome maturation. Adeno-associated virus (AAV)-mediated rescue of WIPI2 reversed the impaired autophagic flux and improved NASH phenotypes in Cox1Δhepa mice, indicating that COX1 deletion-mediated steatohepatitis was partially dependent on WIPI2-mediated autophagy. In conclusion, we demonstrated a novel role of COX1 in hepatic autophagy that protected against NASH by interacting with WIPI2. Targeting the COX1-WIPI2 axis may be a novel therapeutic strategy for NASH.

RESUMO

INTRODUCTION: Online interprofessional education is a collaborative process that emphasizes both individual reflection and shared discourses. A useful analytical tool for understanding the complex dynamics of online collaborative learning is the community of inquiry (CoI) framework, which originally held that there are three types of presence in such learning: teaching, cognitive, and social. However, it was later revised to include learning presence, which is characterized by self-regulated learning. Our study aims to refine the construct of learning presence through a clearer understanding of how self- and co-regulation jointly influence learning outcomes. METHODS: We surveyed 110 people involved with an online interprofessional medical-education curriculum at a university in Hong Kong. Path analysis was adopted to explore the relationships among 1) the three original presences of CoI; 2) learning presence (i.e., for this purpose, a combination of self-regulation and co-regulation); and 3) two learning outcomes: perceived progress and learner satisfaction. RESULTS: The results of path analysis indicated that teaching presence had a significant indirect effect, through co-regulation, on perceived progress. In terms of direct relationships, co-regulation significantly and positively influenced both self-regulation and cognitive presence; and social presence had both positive influence on learners' satisfaction and perceived progress. DISCUSSION: This study's findings suggest the important role of co-regulation in supporting self-regulation, especially in online collaborative-learning environments. Learners' self-regulation skills are shaped by their social interactions and regulatory activities with others. This further implies that health-professions educators and instructional designers should create learning activities that facilitate the development of co-regulatory skills, as a means of improving learning outcomes. As self-regulation is an important skill for health professions learners' lifelong learning, and because their future workplaces will be interdisciplinary in nature, it is critical to provide interactive and collaborative learning environments that will promote co-regulation and self-regulation.

RESUMO

Chronic alcohol consumption causes liver steatosis, cell death, and inflammation. Melatonin (MLT) is reported to alleviate alcoholic liver disease (ALD)-induced injury. However, its direct regulating targets in hepatocytes are not fully understood. In the current study, a cell-based screening model and a chronic ethanol-fed mice ALD model were used to test the protective mechanisms of MLT. MLT ameliorated ethanol-induced hepatocyte injury in both cell and animal models (optimal doses of 10 µmol/L and 5 mg/kg, respectively), including lowered liver steatosis, cell death, and inflammation. RNA-seq analysis and loss-of-function studies in AML-12 cells revealed that telomerase reverse transcriptase (TERT) was a key downstream effector of MLT. Biophysical assay found that epidermal growth factor receptor (EGFR) on the hepatocyte surface was a direct binding and regulating target of MLT. Liver specific knock-down of Tert or Egfr in the ALD mice model impaired MLT-mediated liver protection, partly through the regulation of nuclear brahma-related gene-1 (BRG1). Long-term administration (90 days) of MLT in healthy mice did not cause evident adverse effect. In conclusion, MLT is an efficacious and safe agent for ALD alleviation. Its direct regulating target in hepatocytes is EGFR and downstream BRG1-TERT axis. MLT might be used as a complimentary agent for alcoholics.

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.

RESUMO

BACKGROUND: Team cohesiveness and collective efficacy have been construed as important characteristics of a high-functioning team. However, the psychological mechanism through which they promote positive outcomes remains unknown. Understanding this psychological process is important to teachers and programme implementers to yield actionable interventions that can be used to craft effective practices for optimizing team outcomes. This is especially true in interprofessional education (IPE) in medical education, where a team-based approach to patient management is promoted. Drawing from the social-cognitive theory, we examined a hypothesized model where team cohesiveness predicts collaboration outcomes (teamwork satisfaction, overall satisfaction with the team experience, and IPE goal attainment) via collective efficacy. METHODS: We used data from Chinese medicine, medicine, nursing, and social work students in Hong Kong (n = 285) who were enrolled in IPE. They were invited to respond to scales in two time points. We performed mediation analysis using structural equations modelling to test the indirect effect model: team cohesiveness → collective efficacy → outcomes. RESULTS: Results of structural equation modelling revealed that collective efficacy fully mediated the relationships between team cohesiveness and all three team outcomes, providing support for the hypothesised model [RMSEA = 0.08, NFI = 0.90, CFI = 0.93, IFI = 0.93, TLI = 0.93]. Team cohesiveness predicted the achievement of collaboration outcomes via collective efficacy. CONCLUSION: The findings demonstrated the important roles of team cohesiveness and collective efficacy in promoting successful team collaboration. Team cohesiveness predicted collective efficacy, and collective efficacy, in turn, predicted collaboration outcomes. This study contributed to theorising the pathways towards successful team collaboration outcomes.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVES: Calls to promote team-based interprofessional collaborative practice in managing patients with complex health problems are ubiquitous. However, the literature remains silent on what characterises successful teams in interprofessional education (IPE) and on profiling successful teams. To help conceptualise successful teams, this study investigated the differences in attitudes and achievement between high- and low-performing teams in an online asynchronous and synchronous IPE programme, and the role of autonomous motivation in determining team membership. METHODS: Using extreme case sampling involving health and social care students, we identified ten high-performing teams and seven low-performing teams based on their team composite scores on three interprofessional collaborative outcomes: team effectiveness, goal achievement, and scores on the readiness assurance test. Each team had five to seven members of diverse backgrounds. Independent t-tests were performed to identify differences in interprofessional collaborative outcomes, namely teamwork and collaboration, patient-centredness, diversity and ethics, community-centeredness, and interprofessional biases for the affective domain and application exercise for the cognitive domain. We employed logistic regression in which autonomous motivation was used to predict group membership. RESULTS: High-performing teams were characterised as those whose members endorsed or valued "teamwork and collaboration" in IPE simulations. Compared with the low-performing groups, they better recognised and endorsed diversity and ethics, patient-centeredness, and community-centeredness. Membership to high- and low-performing teams was linked to autonomous motivation. CONCLUSIONS: High-performing teams have higher favourable valuing of important interprofessional collaborative competencies, and membership to which is predicted by autonomous motivation. The results suggest the need to pay special attention to struggling teams to facilitate desirable collaborative competencies, especially in terms of members' motivation. Theoretical, methodological, and practical implications are discussed.

RESUMO

BACKGROUND: The COVID-19 pandemic has exacerbated the pre-existing global crisis of physician burnout. Physician and particularly medical educator well-being, has come into focus as educators can influence their own and learners' well-being. Measuring this construct is one important step towards promoting well-being in the work and learning environments. The 5-item World Health Organization Well-Being Index (WHO-5) has been validated in different populations worldwide for assessing well-being. Yet, its psychometric acceptability remains unexplored among medical educators in Asia including Hong Kong (HK). This study evaluates the validity of the WHO-5 when used among HK medical educators. METHOD: Using data from 435 medical educators, we employed combined within-network (confirmatory factor analysis; CFA) and between-network approaches (correlation and regression) to scale validation. RESULTS: CFA results indicated that our data fit the a priori WHO-5 model, suggesting structural validity. Results of comparison of means indicated no gender differences, but there were significant differences when participants were compared by age and professional backgrounds. Resilience predicted well-being as measured by the WHO-5, suggesting construct criterion validity. CONCLUSIONS: Our findings extend the validity evidence for the WHO-5 to HK medical educators examined in this study. This enables their well-being to be assessed when evaluating the impact of future well-being programmes.

RESUMO

BACKGROUND & AIMS: CREB-H is a key liver-enriched transcription factor governing lipid metabolism. Additional targets of CREB-H remain to be identified and characterized. Here, we identified a novel fasting- and CREB-H-induced (FACI) protein that inhibits intestinal lipid absorption and alleviates diet-induced obesity in mice. METHODS: FACI was identified by reanalysis of existing transcriptomic data. Faci-/- mice were generated by clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9)-mediated genome engineering. RNA sequencing was performed to identify differentially expressed genes in Faci-/- mice. Lipid accumulation in the villi was assessed by triglyceride measurement and Oil red O staining. In vitro fatty acid uptake assay was performed to verify in vivo findings. RESULTS: FACI expression was enriched in liver and intestine. FACI is a phospholipid-binding protein that localizes to plasma membrane and recycling endosomes. Hepatic transcription of Faci was regulated by not only CREB-H, but also nutrient-responsive transcription factors sterol regulatory element-binding protein 1 (SREBP1), hepatocyte nuclear factor 4α (HNF4α), peroxisome proliferator-activated receptor γ coactivator-1α (PGC1α), and CREB, as well as fasting-related cyclic adenosine monophosphate (cAMP) signaling. Genetic knockout of Faci in mice showed an increase in intestinal fat absorption. In accordance with this, Faci deficiency aggravated high-fat diet-induced obesity, hyperlipidemia, steatosis, and other obesity-related metabolic dysfunction in mice. CONCLUSIONS: FACI is a novel CREB-H-induced protein. Genetic disruption of Faci in mice showed its inhibitory effect on fat absorption and obesity. Our findings shed light on a new target of CREB-H implicated in lipid homeostasis.

RESUMO

The Students' Perceptions of Physician-Pharmacist Interprofessional Clinical Education and its revision (SPICE, SPICE-R) were designed to understand medicine and pharmacy students' perceptions of interprofessional education and collaborative practice in managing complex health problems. The SPICE-R authors, however, suggested for additional items for subscales "roles and responsibilities for collaborative care" and "patient outcomes from collaborative practice". We added two items and introduced SPICE-R3 to differentiate it from the 10-item SPICE-R2 and to adapt the scale to a wider range of healthcare members. We administered the SPICE-R3 to healthcare students at the height of the COVID-19 outbreak in Hong Kong in February 2020. Using data from 225 students from Chinese medicine, medicine, nursing, and pharmacy, confirmatory factor analysis indicated nine items having acceptable item coefficients. Our data obtained a good fit to the three-factor, nine-item model suggesting construct validity. Results of the between-network analysis suggest that the three subscales of SPICE-R3 correlated systematically with other theoretically relevant variables in the nomological network suggesting convergent validity. The SPICE-R3 is a valid measure to examine Hong Kong healthcare students' interprofessional attitudes in online interprofessional education even during the pandemic. Implications and directions for future research are provided.

RESUMO

The shift in the way how health care is delivered from exclusive (disciplinary) to a more collective and inclusive (interprofessional) has recently been gaining traction in health care. The need for this shift is even magnified when the health care system face unprecedented challenges that single expertise is no more enough. The promise of transformative power of collaboration in health care suggests that collective intelligence achieves tasks more effectively than a single expertise could achieve.

RESUMO

Students' attitudes toward interprofessional teamwork can be linked to successful interprofessional education. This points to the importance of identifying a scale that may be useful in keeping track of the change in students' attitudes over time. In response to this, using a combination of within- and between-network approaches to construct validity, we examined the psychometric acceptability of the Interprofessional Attitude Scale (IPAS) involving 274 Chinese healthcare and social care pre-licensure students in Hong Kong. Overall results indicated that IPAS had good internal consistency. Results of the confirmatory factor analysis provided support to the overall five-factor solution although one negatively worded item obtained non-significant factor loading. Results of the between-network analysis suggest that various subscales of IPAS correlated systematically with other theoretically relevant variables: teamwork attitudes, communication, and team effectiveness. The IPAS is a valid measure to examine predominantly Chinese healthcare and social care students' interprofessional attitudes in online interprofessional education.

RESUMO

Alcoholic liver disease (ALD) causes insulin resistance, lipid metabolism dysfunction, and inflammation. We investigated the protective effects and direct regulating target of S-allylmercaptocysteine (SAMC) from aged garlic on liver cell injury. A chronic ethanol-fed ALD in vivo model (the NIAAA model) was used to test the protective functions of SAMC. It was observed that SAMC (300 mg/kg, by gavage method) effectively ameliorated ALD-induced body weight reduction, steatosis, insulin resistance, and inflammation without affecting the health status of the control mice, as demonstrated by histological, biochemical, and molecular biology assays. By using biophysical assays and molecular docking, we demonstrated that SAMC directly targeted insulin receptor (INSR) protein on the cell membrane and then restored downstream IRS-1/AKT/GSK3ß signaling. Liver-specific knock-down in mice and siRNA-mediated knock-down in AML-12 cells of Insr significantly impaired SAMC (250 µmol/L in cells)-mediated protection. Restoration of the IRS-1/AKT signaling partly recovered hepatic injury and further contributed to SAMC's beneficial effects. Continuous administration of AKT agonist and recombinant IGF-1 in combination with SAMC showed hepato-protection in the mice model. Long-term (90-day) administration of SAMC had no obvious adverse effect on healthy mice. We conclude that SAMC is an effective and safe hepato-protective complimentary agent against ALD partly through the direct binding of INSR and partial regulation of the IRS-1/AKT/GSK3ß pathway.

RESUMO

The impact of the medical curricular reform on anatomy education has been inconclusive. A pervasive perception is that graduates do not possess a sufficient level of anatomical knowledge for safe medical practice; however, the reason is less well-studied. This qualitative study investigated the perceived challenges in learning anatomy, possible explanations, and ways to overcome these challenges. Unlike previous work, it explored the perceptions of multiple stakeholders in anatomy learning. Semi-structured interviews were conducted and the transcripts were analyzed by a grounded theory approach. Three main themes emerged from the data: (1) visualization of structures, (2) body of information, and (3) issues with curriculum design. The decreasing time spent in anatomy laboratories forced students to rely on alternative resources to learn anatomy but they lacked the opportunities to apply to human specimens, which impeded the "near" transfer of learning. The lack of clinical integration failed to facilitate the "far" transfer of learning. Learners also struggled to cope with the large amount of surface knowledge, which was pre-requisite to successful deep and transfer of learning. It was theorized that the perceived decline in anatomical knowledge was derived from this combination of insufficient surface knowledge and impeded "near" transfer resulting in impeded deep and "far" transfer of learning. Moving forward, anatomy learning should still be cadaveric-based coupled with complementary technological innovations that demonstrate "hidden" structures. A constant review of anatomical disciplinary knowledge with incremental integration of clinical contexts should also be adopted in medical curricula which could promote deep and far transfer of learning.
