Abstract
Introduction The coronavirus disease 2019 (COVID-19) pandemic has caused significant mental distress in populations globally. At the frontline of the pandemic, emergency departments (EDs) are the prime setting to observe the effects of the pandemic on the mental health of the population. We aimed to describe the trend of mental health-related ED attendances at an acute hospital in Singapore before and during the various stages of the COVID-19 pandemic. Methods This is a retrospective, descriptive study of patients who presented to the ED between 1 January 2019 and 31 December 2020. Patients diagnosed with mental health-related systematised nomenclature of medicine who visited the ED during this period were identified and were placed into mental health diagnosis categories for analysis. A comparison was made between patients who presented before the pandemic (2019) and during the pandemic (2020). Results During the study periods, we identified 1,421 patients, of whom 27 were excluded due to non-mental health-related diagnoses, leaving 1,394 patients for analysis. There was a 36.7% increase in mental health-related ED presentations from 2019 to 2020. The proportion of higher-acuity mental health-related ED attendances and number of suicide attempts also increased. Conclusion Our study described an increase in the proportion of high-acuity mental health-related ED attendances during the COVID-19 pandemic. Emergency physicians must be cognisant of the effects of the pandemic on mental health. Further research should be conducted to better equip the healthcare system for handling all aspects of the pandemic.

Abstract
BACKGROUND Communication skills training (CST) remains poorly represented and prioritised in medical schools despite its importance. A systematic scoping review (SSR) of CST is proposed to better appreciate current variability in their structure, content, and assessment. This is to guide their future design in medical school curricula. METHODS The Systematic Evidence-Based Approach (SEBA) was used to guide concurrent SSRs of teaching and assessment in CST. After independent database searches, concurrent thematic and content analysis of included articles were conducted separately. Resultant themes/categories were combined via the jigsaw perspective to provide a more holistic view of the data. These were then compared to tabulated summaries of the included articles to create funnelled domains. RESULTS 52,300 papers were identified, 150 full-text articles included, and four funnelled domains were identified: Indications, Design, Assessment, and Barriers and Enablers of CST. CSTs confer numerous benefits to physicians and patients. It saw increased confidence, improved diagnostic capabilities and better clinical management, as well as greater patient satisfaction and treatment compliance. Skills may be divided into core, prerequisite competencies, and advanced skills pertinent to more challenging and nuanced scenarios - such as population or setting-specific situations. CST teaching and assessment modalities were found to align with Miller's Pyramid, with didactic teaching gradually infused with experiential approaches to enhance their understanding and integration. A plethora of CST frameworks, teaching and assessment methods were identified and are presented together. CONCLUSION While variable in approach, content and assessment, CST in medical schools often employ stage-based curricula to instil competency-based topics of increasing complexity throughout medical school education. This process builds on the application of prior knowledge and skills, influencing practice and, potentially, the students' professional identity formation. In addition, the institution plays a critical role in overseeing training, ensuring longitudinal guidance and holistic assessments of the students' progress.

Abstract
INTRODUCTION The redeployment of mentors and restrictions on in-person face-to-face mentoring meetings during the COVID-19 pandemic has compromised mentoring efforts in Palliative Medicine (PM). Seeking to address these gaps, we evaluate the notion of a combined novice, peer-, near-peer and e-mentoring (CNEP) and interprofessional team-based mentoring (IPT) program. METHODS A Systematic Evidence Based Approach (SEBA) guided systematic scoping review was carried out to study accounts of CNEP and IPT from articles published between 1st January 2000 and 28th February 2021. To enhance trustworthiness, concurrent thematic and content analysis of articles identified from structured database search using terms relating to interprofessional, virtual and peer or near-peer mentoring in medical education were employed to bring together the key elements within included articles. RESULTS Fifteen thousand one hundred twenty one abstracts were reviewed, 557 full text articles were evaluated, and 92 articles were included. Four themes and categories were identified and combined using the SEBA's Jigsaw and Funnelling Process to reveal 4 domains - characteristics, mentoring stages, assessment methods, and host organizations. These domains suggest that CNEP's structured virtual and near-peer mentoring process complement IPT's accessible and non-hierarchical approach under the oversight of the host organizations to create a robust mentoring program. CONCLUSION This systematic scoping review forwards an evidence-based framework to guide a CNEP-IPT program. At the same time, more research into the training and assessment methods of mentors, near peers and mentees, the dynamics of mentoring interactions and the longitudinal support of the mentoring relationships and programs should be carried out.

Abstract
BACKGROUND Recognizing that physicians may struggle to achieve knowledge, skills, attitudes and or conduct at one or more stages during their training has highlighted the importance of the 'deliberate practice of improving performance through practising beyond one's comfort level under guidance'. However, variations in physician, program, contextual and healthcare and educational systems complicate efforts to create a consistent approach to remediation. Balancing the inevitable disparities in approaches and settings with the need for continuity and effective oversight of the remediation process, as well as the context and population specific nature of remediation, this review will scrutinise the remediation of physicians in training to better guide the design, structuring and oversight of new remediation programs. METHODS Krishna's Systematic Evidence Based Approach is adopted to guide this Systematic Scoping Review (SSR in SEBA) to enhance the transparency and reproducibility of this review. A structured search for articles on remediation programs for licenced physicians who have completed their pre-registration postings and who are in training positions published between 1st January 1990 and 31st December 2021 in PubMed, Scopus, ERIC, Google Scholar, PsycINFO, ASSIA, HMIC, DARE and Web of Science databases was carried out. The included articles were concurrently thematically and content analysed using SEBA's Split Approach. Similarities in the identified themes and categories were combined in the Jigsaw Perspective and compared with the tabulated summaries of included articles in the Funnelling Process to create the domains that will guide discussions. RESULTS The research team retrieved 5512 abstracts, reviewed 304 full-text articles and included 101 articles. The domains identified were characteristics, indications, frameworks, domains, enablers and barriers and unique features of remediation in licenced physicians in training programs. CONCLUSION Building upon our findings and guided by Hauer et al. approach to remediation and Taylor and Hamdy's Multi-theories Model, we proffer a theoretically grounded 7-stage evidence-based remediation framework to enhance understanding of remediation in licenced physicians in training programs. We believe this framework can guide program design and reframe remediation's role as an integral part of training programs and a source of support and professional, academic, research, interprofessional and personal development.

Abstract
BACKGROUND The COVID-19 pandemic has changed the healthcare landscape drastically. Stricken by sharp surges in morbidity and mortality with resource and manpower shortages confounding their efforts, the medical community has witnessed high rates of burnout and post-traumatic stress amongst themselves. Whilst the prevailing literature has offered glimpses into their professional war, no review thus far has collated the deeply personal reflections of physicians and ascertained how their self-concept, self-esteem and perceived self-worth has altered during this crisis. Without adequate intervention, this may have profound effects on their mental and physical health, personal relationships and professional efficacy. METHODS With mentions of the coronavirus pervading social media by the millions, this paper set out to collate and thematically analyse social media posts containing first-person physician reflections on how COVID-19 affected their lives and their coping mechanisms. A consistent search strategy was employed and a PRISMA flowchart was used to map out the inclusion/exclusion criteria. RESULTS A total of 590 social media posts were screened, 511 evaluated, and 108 included for analysis. Salient themes identified include Disruptions to Personal Psycho-Emotional State, Disruptions to Professional Care Delivery, Concern for Family, Response from Institution, Response from Society and Coping Mechanisms. CONCLUSION It is evident that the distress experienced by physicians during this time has been manifold, multi-faceted and dominantly negative. Self-concepts were distorted with weakened self-esteem and perceived self-worth observed. The Ring Theory of Personhood (RToP) was adopted to explain COVID-19's impact on physician personhood as it considers existential, individual, relational and social concepts of the self. These entwined self-concepts serve as 'compensatory' to one another, with coping mechanisms buffering and fortifying the physician's overall personhood. With healthcare institutions playing a vital role in providing timely and targeted support, it was further proposed that a comprehensive assessment tool based on the RToP could be developed to detect at-risk physicians and evaluate the presence and effectiveness of established support structures.

Abstract
BACKGROUND Amidst expanding roles in education and policy making, questions have been raised about the ability of Clinical Ethics Committees (CEC) s to carry out effective ethics consultations (CECons). However recent reviews of CECs suggest that there is no uniformity to CECons and no effective means of assessing the quality of CECons. To address this gap a systematic scoping review of prevailing tools used to assess CECons was performed to foreground and guide the design of a tool to evaluate the quality of CECons. METHODS Guided by Levac et al's (2010) methodological framework for conducting scoping reviews, the research team performed independent literature reviews of accounts of assessments of CECons published in six databases. The included articles were independently analyzed using content and thematic analysis to enhance the validity of the findings. RESULTS Nine thousand sixty-six abstracts were identified, 617 full-text articles were reviewed, 104 articles were analyzed and four themes were identified - the purpose of the CECons evaluation, the various domains assessed, the methods of assessment used and the long-term impact of these evaluations. CONCLUSION This review found prevailing assessments of CECons to be piecemeal due to variable goals, contextual factors and practical limitations. The diversity in domains assessed and tools used foregrounds the lack of minimum standards upheld to ensure baseline efficacy. To advance a contextually appropriate, culturally sensitive, program specific assessment tool to assess CECons, clear structural and competency guidelines must be established in the curation of CECons programs, to evaluate their true efficacy and maintain clinical, legal and ethical standards.

Abstract
INTRODUCTION Clinical ethics committees (CECs) support and enhance communication and complex decision making, educate healthcare professionals and the public on ethical matters and maintain standards of care. However, a consistent approach to training members of CECs is lacking. A systematic scoping review was conducted to evaluate prevailing CEC training curricula to guide the design of an evidence-based approach. METHODS Arksey and O'Malley's methodological framework for conducting scoping reviews was used to evaluate prevailing accounts of CEC training published in six databases. Braun and Clarke's thematic analysis approach was adopted to thematically analyse data across different healthcare and educational settings. RESULTS 7370 abstracts were identified, 92 full-text articles were reviewed and 55 articles were thematically analysed to reveal four themes: the design, pedagogy, content and assessment of CEC curricula. CONCLUSION Few curricula employ consistent approaches to training. Many programmes fail to provide CEC trainees with sufficient knowledge, skills and experience to meet required competencies. Most programmes do not inculcate prevailing sociocultural, research, clinical and educational considerations into training processes nor provide longitudinal support for CEC trainees. Most CEC training programmes are not supported by host institutions threatening the sustainability of the programme and compromising effective assessment and longitudinal support of CEC trainees. While further reviews are required, this review underlines the need for host organisations to support and oversee a socioculturally appropriate ethically sensitive, clinically relevant longitudinal training, assessment and support process for CEC trainees if CECs are to meet their roles effectively.

Abstract
The metastasis suppressor, N-myc downstream regulated gene-1 (NDRG1), is a stress response protein that is involved in the inhibition of multiple oncogenic signaling pathways. Initial studies have linked NDRG1 and the endoplasmic reticulum (ER) stress response. Considering this, we extensively examined the mechanism by which NDRG1 regulates the ER stress response in pancreatic and colon cancer cells. We also examined the anti-cancer agent, di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT), which induces NDRG1 expression and causes ER stress. The expression of NDRG1 was demonstrated to regulate the three main arms of the ER stress response by: (1) increasing the expression of three major ER chaperones, binding immunoglobulin protein (BiP), calreticulin, and calnexin; (2) suppressing the protein kinase, RNA-activated (PKR)-like ER kinase (PERK); (3) inhibiting the inositol-requiring kinase 1α (IRE1α) arm; and (4) increasing the cleavage of activating transcription factor 6 (ATF6). An important finding was that NDRG1 enhances the anti-proliferative and anti-migratory activity of Dp44mT. This increased efficacy could be related to the following effects in the presence of Dp44mT and NDRG1, namely: markedly increased activation of the PERK target, eukaryotic translation initiation factor 2α (eIF2α); the maintenance of activating transcription factor 4 (ATF4) expression; high cytosolic Ca+2 that increases the sensitivity of cells to apoptosis via activation of the calmodulin-dependent kinase II (CaMKII) signaling cascade; and increased pro-apoptotic C/EBP-homologous protein (CHOP) expression. Collectively, this investigation dissects the molecular mechanisms through which NDRG1 manipulates the ER stress response and its ability to potentiate the activity of the potent anti-cancer agent, Dp44mT.
