RESUMEN

The developmental origin of blood-forming hematopoietic stem cells (HSCs) is a longstanding question. Here, our non-invasive genetic lineage tracing in mouse embryos pinpoints that artery endothelial cells generate HSCs. Arteries are transiently competent to generate HSCs for 2.5 days (∼E8.5-E11) but subsequently cease, delimiting a narrow time frame for HSC formation in vivo. Guided by the arterial origins of blood, we efficiently and rapidly differentiate human pluripotent stem cells (hPSCs) into posterior primitive streak, lateral mesoderm, artery endothelium, hemogenic endothelium, and >90% pure hematopoietic progenitors within 10 days. hPSC-derived hematopoietic progenitors generate T, B, NK, erythroid, and myeloid cells in vitro and, critically, express hallmark HSC transcription factors HLF and HOXA5-HOXA10, which were previously challenging to upregulate. We differentiated hPSCs into highly enriched HLF+ HOXA+ hematopoietic progenitors with near-stoichiometric efficiency by blocking formation of unwanted lineages at each differentiation step. hPSC-derived HLF+ HOXA+ hematopoietic progenitors could avail both basic research and cellular therapies.

RESUMEN

Partial reprogramming by cyclic short-term expression of Yamanaka factors holds promise for shifting cells to younger states and consequently delaying the onset of many diseases of aging. However, the delivery of transgenes and potential risk of teratoma formation present challenges for in vivo applications. Recent advances include the use of cocktails of compounds to reprogram somatic cells, but the characteristics and mechanisms of partial cellular reprogramming by chemicals remain unclear. Here, we report a multi-omics characterization of partial chemical reprogramming in fibroblasts from young and aged mice. We measured the effects of partial chemical reprogramming on the epigenome, transcriptome, proteome, phosphoproteome, and metabolome. At the transcriptome, proteome, and phosphoproteome levels, we saw widescale changes induced by this treatment, with the most notable signature being an upregulation of mitochondrial oxidative phosphorylation. Furthermore, at the metabolome level, we observed a reduction in the accumulation of aging-related metabolites. Using both transcriptomic and epigenetic clock-based analyses, we show that partial chemical reprogramming reduces the biological age of mouse fibroblasts. We demonstrate that these changes have functional impacts, as evidenced by changes in cellular respiration and mitochondrial membrane potential. Taken together, these results illuminate the potential for chemical reprogramming reagents to rejuvenate aged biological systems and warrant further investigation into adapting these approaches for in vivo age reversal.

RESUMEN

Lysosomes critically rely on bis(monoacylglycero)phosphate (BMP) to stimulate lipid catabolism, cholesterol homeostasis, and lysosomal function. Alterations in BMP levels in monogenic and complex neurodegeneration suggest an essential function in human health. However, the site and mechanism responsible for BMP synthesis have been subject to debate for decades. Here, we report that the Batten disease gene product CLN5 is the elusive BMP synthase (BMPS). BMPS-deficient cells exhibited a massive accumulation of the BMP synthesis precursor lysophosphatidylglycerol (LPG), depletion of BMP species, and dysfunctional lipid metabolism. Mechanistically, we found that BMPS mediated synthesis through an energy-independent base exchange reaction between two LPG molecules with increased activity on BMP-laden vesicles. Our study elucidates BMP biosynthesis and reveals an anabolic function of late endosomes/lysosomes.

RESUMEN

Healthy eating is vital in preventing obesity and long-term non-communicable diseases. This study explores potential family facilitators of, barriers to and strategies for healthy eating among adolescents in Chinese families to guide the development of effective interventions in the future. Parent-adolescent dyads were purposively sampled by age, gender, fruit and vegetable intake and household income. Key family factors were identified by thematic analysis. Fourteen themes under five domains were identified: family health with (1) illness experienced in the family; parental knowledge of (2) dietary recommendations, (3) the preparation of healthy food and (4) healthy food choice; parental attitudes towards (5) the importance of healthy eating and (6) the priority of family health; socioeconomic factors of (7) time concerns and (8) cost concerns; and food parenting practices in (9) nutritional education, (10) role modeling, (11) food provision, (12) child involvement, (13) parental supervision and (14) the cultivation of food preference. Useful strategies included incorporating healthy ingredients in adolescents' favorite recipes and providing a variety of fruit and vegetables at home. There is a need to empower parents with practical nutrition knowledge, to be more authoritative in food parenting practices, to discuss healthy eating with children and to acquire practical skills related to time- and cost-saving healthy cooking.

RESUMEN

To tackle unhealthy eating among adolescents, it is crucial to understand the dietary knowledge, attitudes, and practices (KAP) on which adolescent eating habits are based. This qualitative study identifies the gaps in KAP by exploring what Chinese adolescents know, perceive, and practice regarding healthy eating to better inform targeted interventions for this important health problem. Parent-adolescent dyads were purposively sampled based on, for example, the dietary intake, age, and gender of the adolescent and household income, and each completed a 30 to 60 min interview. Twelve themes were synthesized: knowledge: (1) dietary recommendations, (2) health outcomes of healthy eating, (3) nutrition content in food, and (4) access to healthy meals; attitudes: (5) outcome expectation for healthy eating, (6) food preferences, and (7) self-efficacy regarding adopting healthy eating; and practices: (8) going grocery shopping for healthy food, (9) eating home-prepared meals. (10) eating out in restaurants or consuming takeaway food, (11) fruit and vegetable consumption, and (12) snacking, perceived unhealthy eating to be low risk, made unhealthy choices regarding snacking and eating out, and had insufficient fruit and vegetable intake. Programs should emphasize the positive short-term health outcomes of healthy eating and empower adolescents to acquire food preparation skills to sustain healthy eating habits.

RESUMEN

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.

RESUMEN

Promoting healthy eating habits can prevent adolescent obesity in which family may play a significant role. This review synthesized findings from qualitative studies to identify family barriers and facilitators of adolescent healthy eating in terms of knowledge, attitudes, and practices (KAP). A literature search of four databases was completed on 31 July 2020; qualitative studies that explored family factors of adolescent (aged 10 to 19 years) eating habits were included. A total of 48 studies were identified, with the majority being from North America and sampled from a single source. Ten themes on how family influences adolescent dietary KAP were found: Knowledge-(1) parental education, (2) parenting style, and (3) family illness experience; Attitudes-(4) family health, (5) cultivation of preference, and (6) family motivation; Practices-(7) home meals and food availability, (8) time and cost, (9) parenting style, and (10) parental practical knowledge and attitudes. This review highlights five parental characteristics underlying food parenting practices which affect adolescents' KAP on healthy eating. Adolescents with working parents and who are living in low-income families are more vulnerable to unhealthy eating. There is a need to explore cultural-specific family influences on adolescents' KAP, especially regarding attitudes and food choices in Asian families.

RESUMEN

BACKGROUND: Teamwork and collaboration are central to interprofessional education but fostering these attributes in large undergraduate cohorts is challenging. OBJECTIVES: This study aimed to examine the complexities of IPE group learning processes by examining how the material and intersubjective intertwine when newly formed interprofessional groups (Chinese medicine, medicine, nursing, pharmacy, and social work) synchronously engaged with face-to-face and online learning in a blended, team-based learning environment. METHODS: It was a micro-ethnography study using a sociomaterial theoretical lens. We selected two undergraduate interprofessional healthcare student groups within a large scale programme for contrastive video analysis of synchronous spatial and physical configurations, associated talk, and online activity. RESULTS: Video analysis of evolving physical configurations indicated that Group B was spatially more evenly grouped, and physically orientated to an identifiable leader, despite their blinded peer evaluations indicating distributed leadership. Group A faced a critical event at a public forum leading to spatial disruption breaking into subgroups and isolates; however, this group identified one member as a defined leader in the peer evaluations. CONCLUSIONS: Based on online scores, we found that peer identification of leaders may influence learning processes but not learning outcomes in the first IPE team meeting. The design of the physical and virtual learning environments contributed to the developing, sociomaterial processes of group cohesion in interprofessional team-based learning.

RESUMEN

AIM: To investigate the assocation between glycated haemoglobin (HbA1c) level and cardiovascular disease (CVD) risk among patients with type 2 diabetes. MATERIALS AND METHODS: This retrospective cohort study conducted in Hong Kong selected patients aged 45 to 84 years with type 2 diabetes mellitus and without CVD from primary care clinics during the period 2008 to 2010. Usual HbA1c measurement was calculated using a mixed-effects model to minimize regression dilution bias. The association between usual HbA1c and CVD risk was assessed by Cox regression, with adjustment for baseline covariates. Subgroup analyses by patient characteristics were also conducted. RESULTS: After a median follow-up period of 8.4 years (1.4 million person-years), 174 028 patients with 34 074 CVD events were observed. A curvilinear association was found between usual HbA1c and total CVD, stroke, heart failure and CVD mortality risk. No significant difference was found among patients with usual HbA1c <53 mmol/mol (7%). A positive linear association was found between usual HbA1c and the risks of outcomes when the usual HbA1c was 53 mmol/mol (7%) or above. The adjusted hazard ratios (HRs) for CVD risk per 1% increment in usual HbA1c >7% was 21% (HR 1.21, 95% confidence interval [CI] 1.18-1.23) (HR for CVD per 1mmol/mol increment in usual HbA1c > 53 mmol/mol was 1.7% (HR 1.017, CI 1.015-1.019)). A similar pattern was identified in a patient subgroup analysis, but the effects of usual HbA1c in younger patients were more prominent than in older patients. CONCLUSIONS: Usual HbA1c increments for levels >53 mmol/mol (7.0%) were associated with elevated CVD risk, but no difference was found in the population with usual HbA1c <53 mmol/mol (7.0%), irrespective of patient characteristics. For CVD prevention, strict adherence to an HbA1c target of <53 mmol/mol (7%) should apply to younger patients.

RESUMEN

BACKGROUND: To compare the health-related quality of life (HRQOL) and health utility of Chinese patients with end-stage renal disease (ESRD) undergoing nocturnal home haemodialysis (Home HD) against those patients undergoing other modes of dialysis. METHODS: Chinese ESRD patients undergoing Home HD were recruited in renal specialist outpatient clinics at three public hospitals in Hong Kong. SF-12 Health Survey (SF-12) was used to measure HRQOL and generate the SF-6D heath utility score. Mean scores of SF-12 domains, physical and mental component summary and SF-6D health utility of 41 patients undergoing Home HD were compared with available scores of patients receiving other forms of dialysis, namely, peritoneal dialysis (PD) (n = 103), hospital in-centre HD (n = 135) or community in-centre HD (n = 118). Adjusted linear regression models were used to examine the impact of mode of dialysis on the HRQOL and health utility scores, accounting for the sociodemographic and clinical characteristics. RESULTS: ESRD patients undergoing PD and community in-centre HD had better health utility, physical and mental component summary scores than the hospital in-centre HD. Adjusted analysis showed that hospital in-centre HD reported worse physical component summary and health utility scores when compared with PD and community in-centre HD. CONCLUSION: HRQOL and health utility scores of patients undergoing Home HD were similar to those undergoing PD and community in-centre HD. Better physical aspects of HRQOL and health utility was observed in PD and community-based HD than hospital in-centre HD, providing evidence for the increase in capacity of non-hospital-based HD, which provided flexibility as well as patient centredness and empowerment in Hong Kong.

RESUMEN

This article was migrated. The article was marked as recommended. This article reviews the development of medical humanities pedagogies in Taiwan, China and Hong Kong. We reflect on the curricula formation and implementation regarding their interdisciplinary nature and point out the challenges educators face under the climate of current university practices. We first indicate that the emergence of medical humanities in the three societies was enabled by various social forces across the Strait. It also depended on opportunities offered by the higher education reform. We then provide a detailed experience of interdisciplinary team building at The University of Hong Kong, followed by a critical reflection on the challenges of medical humanities along the pursuit of internationalisation among universities in three Chinese societies. We find that the clashing objectives under universities' strategic planning framework could lead to changes in work environments and research practices, hampering the design and the delivery of the curricula. In the end, the idealised promise of the interdisciplinarity of such curricula could become fugacious.

RESUMEN

BACKGROUND: Haemodialysis (HD) is one of the life-saving options for patients with end stage renal disease but demand for this treatment exceeds capacity in publicly funded hospitals. One novel approach to addressing this problem is through a shared-care model whereby government hospitals partner with qualified private HD service providers to increase the accessibility of HD for needy patients. The aim of this study is to evaluate and enhance the quality of care (QOC) provided in such a shared-care programme in Hong Kong, the Haemodialysis Public-Private Partnership Programme (HD-PPP). METHODS/DESIGN: This is a longitudinal study based on Action Learning and Audit Spiral methodologies to measure the achievement of pre-set target standards for the HD-PPP programme over three evaluation cycles. The QOC evaluation framework is comprised of structure, process and outcome criteria with target standards in each domain developed from review of the evidence and in close collaboration with the HD-PPP working group. During each evaluation cycle, coordinators of each study site complete a questionnaire to determine adherence with structural criteria of care. Process and clinical outcomes, such as adverse events and dialysis adequacy, are extracted from the patient records of consenting study participants while face-to-face interviews are conducted to ascertain patient-reported outcomes such as self-efficacy and health-related quality of life. DISCUSSION: The study relies on the successful implementation of partnership-based action research to develop an evidence-based and pragmatic framework for evaluation of quality of care in an iterative fashion, and to use it to identify possible areas of quality enhancements in a shared-care programme for HD patients. The approach we take in this study emphasizes partnership and engagement with the clinical and administrative programme team, a robust but flexible evaluation framework, direct observation and the potential to realize positive change. The experience will be useful to inform the process of coordinating research studies involving multiple stakeholders and results will help to guide service planning and policy decision making. TRIAL REGISTRATION: US Clinical Trial Registry NCT02307903.

RESUMEN

AIM: The aim of this study was to evaluate the validity, reliability and sensitivity of the disease-specific items of the Kidney Disease Quality of Life-36 (KDQOL-36) in Chinese patients undergoing maintenance dialysis. METHODS: The content validity was assessed by content validity index (CVI) in ten subjects. 356 subjects were recruited for pilot psychometric testing. The internal construct validity was assessed by corrected item-subscale total correlation. Confirmatory factor analysis (CFA) was used to confirm the factor structure. The convergent validity was assessed by Pearson's correlation test between the disease specific subscale scores and SF-12 version 2 Health Survey (SF-12 v2) scores. The reliability was assessed by the internal consistency (Cronbach's Alpha coefficient) and 2-week test-retest reliability (intraclass correlation coefficient (ICC)). The sensitivity was determined by performing known group comparisons by independent t-test. RESULTS: The CVI on clarity and relevance was ≥ 0.9 for all items. Corrected item- total correlation scores were ≥0.4 for all, except an item related to problems with access site. CFA confirmed the 3-factor structure of the disease-specific component of the KDQOL-36. The correlation coefficients between the disease-specific domain scores and the SF-12 v2 physical and mental component summary scores ranged from 0.328 to 0.492. The reliability was good (Cronbach's alpha coefficients ranged from 0.810 to 0.931, ICC ranged from 0.792 to 0.924). Only the effect subscale was sensitive in detecting differences in HRQOL between haemodialysis and peritoneal dialysis patients, with effect size = 0.68. CONCLUSION: The disease-specific items of the KDQOL-36 are a valid, reliable and sensitive measure to assess the health-related quality of life of Chinese patients on maintenance dialysis.

RESUMEN

AIM: Little is known about the effect of haemodialysis (HD) setting on outcomes of patients with end stage renal disease (ESRD). The study aimed at comparing clinical outcomes and patient-reported outcomes (PRO) of patients on community-based (CBHD) and hospital-based haemodialysis (HBHD). METHODS: A prospective cohort of Chinese ESRD patients receiving HBHD (n = 89) or CBHD (n = 117) in Hong Kong were followed up for 12 months. Subjects were assessed on clinical outcomes of dialysis adequacy (Kt/V) and blood haemoglobin and PRO of health-related quality of life (SF-12v2), general health condition (Global Rating Scale (GRS)) and confidence to cope with their illness (Patient Enablement Instrument (PEI)). Differences between groups were analyzed by independent t-tests for the SF-12v2, GRS and PEI scores. χ(2) tests were used to analyze the difference in proportion of patients reaching the targets of Kt/V and blood haemoglobin and with GRS > 0 and PEI > 0. Multiple linear and logistic regressions were performed to assess the adjusted difference-in-difference estimation. RESULTS: The mean PEI and GRS scores of CBHD patients at 12 months were significantly higher than those of HBHD patients. CBHD patients had significantly greater improvement in self-efficacy and were more likely to be enabled after 12 months than the HBHD patients. CONCLUSION: The study showed similar clinical outcomes and PRO between CBHD and HBHD but CBHD was more effective than HBHD in promoting patient enablement over a 12-month period. The results suggest added value for patients receiving CBHD and support the transfer of HD care from the hospital to the community.

RESUMEN

BACKGROUND: Haemodialysis (HD) is a life-saving but burdensome therapy for patients with end-stage renal disease (ESRD) which can have a detrimental impact on patients' quality of life and outcomes. There is currently little data on the health related quality of life (HRQOL) of Chinese ESRD patients undergoing HD and this study sought to examine the patterns of HRQOL and its associated factors within this population, as well as in comparison with the general local population. METHODS: A cross-sectional study of 244 ESRD patients receiving HD in the hospital and in the community in Hong Kong was conducted using the Short Form-12 Health Survey version 2 (SF-12v2). All study subjects were one-to-one matched with subjects in a Hong Kong general population database by sex and exact age. Independent t-tests were performed to compare the mean SF-12v2 scores between HD patients and the general population, followed by one-way analysis of variance with post hoc Tukey's HSD tests to compare community-based haemodialysis, hospital-based haemodialysis and the general population. Multiple linear regressions were used to identify the factors (socio-demographic, clinical characteristics and comorbidities) associated with the HRQOL scores of ESRD patients receiving HD. RESULTS: The SF-12v2 Physical Functioning, Role Physical, Bodily Pain, General Health and Physical Component Summary scores of HD patients were significantly lower than the age-sex adjusted general population. However, the SF-12v2 Mental Health and Mental Component Summary scores of HD patients were significantly higher than the corresponding general population. Poorer HRQOL was associated with being female, smoking, unemployment and hospital-based haemodialysis. CONCLUSIONS: HD patients had substantially poorer physical HRQOL but better mental HRQOL than the age-sex adjusted general population. Patients receiving HD in the community setting had better HRQOL. Reasons for these observations will need to be further investigated. Those patients who are female, smokers and unemployed may warrant more attention as their poorer HRQOL may be associated with poorer outcomes.

RESUMEN

INTRODUCTION: The Consultation and Relational Empathy (CARE) measure developed and validated in primary care settings and used for general practitioner appraisal is a 10-item instrument used by patients to assess doctors' empathy. The aim of this study is to investigate the validity of the CARE measure in assessing medical students' empathy during a formative family medicine clinical test. METHOD: All 158 final-year medical students were assessed by trained simulated patients (SPs) - who completed the CARE measure, the Jefferson Scale of Patient Perceptions of Physician Empathy (JSPPPE), and a global rating score to assess students' empathy and history-taking ability. RESULTS: Exploratory and confirmatory factor analysis identified a unidimensional structure. The CARE measure strongly correlated with both convergent measures: global rating (ρ=0.79 and <0.001) and JSPPPE (ρ=0.77 and <0.001) and weakly correlated with the divergent measure: history-taking score (ρ=0.28 and <0.001). Internal consistency was excellent (Cronbach's α=0.94). CONCLUSION: The CARE measure had strong construct and internal reliability in a formative, undergraduate family medicine examination. Its role in higher stakes examinations and other educational settings should be explored.

RESUMEN

BACKGROUND: To provide patient-centred holistic care, doctors must possess good interpersonal and empathic skills. Medical schools traditionally adopt a skills-based approach to such training but creative engagement with the arts has also been effective. A novel arts-based approach may help medical students develop empathic understanding of patients and thus contribute to medical students' transformative process into compassionate doctors. This study aimed to evaluate the impact of an arts-making workshop on medical student empathy. METHODS: This was a mixed-method quantitative-qualitative study. In the 2011-12 academic year, all 161 third year medical students at the University of Hong Kong were randomly allocated into either an arts-making workshop or a problem-solving workshop during the Family Medicine clerkship according to a centrally-set timetable. Students in the arts-making workshop wrote a poem, created artwork and completed a reflective essay while students in the conventional workshop problem-solved clinical cases and wrote a case commentary. All students who agreed to participate in the study completed a measure of empathy for medical students, the Jefferson Scale of Empathy (JSE) (student version), at the start and end of the clerkship. Quantitative data analysis: Paired t-test and repeated measures ANOVA was used to compare the change within and between groups respectively. Qualitative data analysis: Two researchers independently chose representational narratives based on criteria adapted from art therapy. The final 20 works were agreed upon by consensus and thematically analysed using a grounded theory approach. RESULTS: The level of empathy declined in both groups over time, but with no statistically significant differences between groups. For JSE items relating to emotional influence on medical decision making, participants in the arts-making workshop changed more than those in the problem-solving workshop. From the qualitative data, students perceived benefits in arts-making, and gained understanding in relation to self, patients, pain and suffering, and the role of the doctor. CONCLUSIONS: Though quantitative findings showed little difference in empathy between groups, arts-making workshop participants gained empathic understanding in four different thematic areas. This workshop also seemed to promote greater self-awareness which may help medical students recognize the potential for emotions to sway judgment. Future art workshops should focus on emotional awareness and regulation.
