Good syndrome (GS) is a rare acquired immunodeficiency disease characterized by the presence of thymoma with combined B and T cell immunodeficiency in adults. Recurrent bacterial infections, particularly sinopulmonary infections caused by encapsulated bacteria, remain the most common infective presentation of GS; however, relapsing viral infections have also been reported, likely due to impaired T cell-mediated immunity. Relapsing COVID-19 infection, however, has not been previously reported as a manifestation of GS. We present two cases of relapsing COVID-19 infection in patients with GS; in one case, relapsing COVID-19 was the first manifestation of newly diagnosed GS.

Abstract Background Introduction to a multi-professional team who are working and caring for the dying, and facing complex moral and ethical dilemmas during Oncology and Palliative Medicine postings influence a medical student’s professional identity formation (PIF). However, limited appreciation of PIF, inadequate assessments and insufficient support jeopardise this opportunity to shape how medical students think, feel and act as future physicians. To address this gap, a systematic scoping review (SSR) of PIF assessment methods is proposed. Methods A Systematic Evidence-based Approach (SEBA) guided SSR of assessments of PIF in medical schools published between 1st January 2000 and 31st December 2021 in PubMed, Embase, ERIC and Scopus databases was carried out. Included articles were concurrently content and thematically analysed using SEBA’s Split Approach and the themes and categories identified were combined using SEBA’s Jigsaw Perspective. The review hinged on the following questions: “what is known about the assessment of professional identity formation amongst medical students?”, “what are the theories and principles guiding the assessment of professional identity formation amongst medical students?”, “what factors influence PIF in medical students?”, “what are the tools used to assess PIF in medical students?”, and “what considerations impact the implementation of PIF assessment tools amongst medical students?”. Results Two thousand four hundred thirty six abstracts were reviewed, 602 full-text articles were evaluated, and 88 articles were included. The 3 domains identified were 1) theories, 2) assessment, and 3) implementation in assessing PIF. Differing attention to the different aspects of the PIF process impairs evaluations, jeopardise timely and appropriate support of medical students and hinder effective implementation of PIF assessments. Conclusion The Krishna-Pisupati model combines current theories and concepts of PIF to provide a more holistic perspective of the PIF process. Under the aegis of this model, Palliative Care and Oncology postings are envisaged as Communities of Practice influencing self-concepts of personhood and identity and shaping how medical students see their roles and responsibilities as future physicians. These insights allow the forwarding of nine recommendations to improve assessments of PIF and shape the design of a PIF-specific tool that can direct timely and personalized support of medical students.

Objectives Guiding the development of longitudinal competencies in communication, ethics and professionalism underlines the role of portfolios to capture and evaluate the multiple multisource appraisals and direct personalised support to clinicians. However, a common approach to these combined portfolios continues to elude medical practice. A systematic scoping review is proposed to map portfolio use in training and assessments of ethics, communication and professionalism competencies particularly in its inculcation of new values, beliefs and principles changes attitudes, thinking and practice while nurturing professional identity formation. It is posited that effective structuring of portfolios can promote self-directed learning, personalised assessment and appropriate support of professional identity formation.Design Krishna’s Systematic Evidence-Based Approach (SEBA) is employed to guide this systematic scoping review of portfolio use in communication, ethics and professionalism training and assessment.Data sources PubMed, Embase, PsycINFO, ERIC, Scopus and Google Scholar databases.Eligibility criteria Articles published between 1 January 2000 and 31 December 2020 were included.Data extraction and synthesis The included articles are concurrently content and thematically analysed using the split approach. Overlapping categories and themes identified are combined using the jigsaw perspective. The themes/categories are compared with the summaries of the included articles in the funnelling process to ensure their accuracy. The domains identified form the framework for the discussion.Results 12 300 abstracts were reviewed, 946 full-text articles were evaluated and 82 articles were analysed, and the four domains identified were indications, content, design, and strengths and limitations.Conclusions This review reveals that when using a consistent framework, accepted endpoints and outcome measures, longitudinal multisource, multimodal assessment data fashions professional and personal development and enhances identity construction. Future studies into effective assessment tools and support mechanisms are required if portfolio use is to be maximised.

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 Molding competent clinicians capable of applying ethics principles in their practice is a challenging task, compounded by wide variations in the teaching and assessment of ethics in the postgraduate setting. Despite these differences, ethics training programs should recognise that the transition from medical students to healthcare professionals entails a longitudinal process where ethics knowledge, skills and identity continue to build and deepen over time with clinical exposure. A systematic scoping review is proposed to analyse current postgraduate medical ethics training and assessment programs in peer-reviewed literature to guide the development of a local physician training curriculum. Methods With a constructivist perspective and relativist lens, this systematic scoping review on postgraduate medical ethics training and assessment will adopt the Systematic Evidence Based Approach (SEBA) to create a transparent and reproducible review. Results The first search involving the teaching of ethics yielded 7669 abstracts with 573 full text articles evaluated and 66 articles included. The second search involving the assessment of ethics identified 9919 abstracts with 333 full text articles reviewed and 29 articles included. The themes identified from the two searches were the goals and objectives, content, pedagogy, enabling and limiting factors of teaching ethics and assessment modalities used. Despite inherent disparities in ethics training programs, they provide a platform for learners to apply knowledge, translating it to skill and eventually becoming part of the identity of the learner. Illustrating the longitudinal nature of ethics training, the spiral curriculum seamlessly integrates and fortifies prevailing ethical knowledge acquired in medical school with the layering of new specialty, clinical and research specific content in professional practice. Various assessment methods are employed with special mention of portfolios as a longitudinal assessment modality that showcase the impact of ethics training on the development of professional identity formation (PIF). Conclusions Our systematic scoping review has elicited key learning points in the teaching and assessment of ethics in the postgraduate setting. However, more research needs to be done on establishing Entrustable Professional Activities (EPA)s in ethics, with further exploration of the use of portfolios and key factors influencing its design, implementation and assessment of PIF and micro-credentialling in ethics practice.

Abstract Background The extension of palliative care services to meet the needs of patients with chronic non-malignant life-limiting conditions faces misconceptions amongst healthcare professionals. A study of prevailing perceptions of healthcare professionals on this wider palliative care service was thus conducted to identify current obstacles, guide the education of local healthcare professionals and improve service accessibility. Methods A cross-sectional study was carried out at the Singapore General Hospital. An anonymised and close-ended online questionnaire was disseminated to 120 physicians and 500 nurses in the Department of Internal Medicine. The online survey tool focused on participant demographics; perceptions of palliative care and its perceived benefits; roles and indications; and attitudes and behaviours towards palliative care referrals. Results Forty four physicians and 156 nurses suggested that care of terminally ill patients with chronic non-malignant life-limiting conditions are compromised by concerns over the role of palliative care in non-cancer care and lapses in their prognostication and communication skills. Respondents also raised concerns about their ability to confront sociocultural issues and introduce palliative care services to patients and their families. Conclusions Gaps in understanding and the ability of nurses and physicians to communicate end of life issues, introduce palliative care services to patients and their families and confront sociocultural issues suggest the need for a longitudinal training program. With similar concerns likely prevalent in other clinical settings within this island nation, a concerted national education program targeting obstacles surrounding effective palliative care should be considered.

Retrospective contact tracing, enabled by the use of automated visitor-management systems and digital contact tracing, together with rapid antigen detection (RAD) for SARS-CoV-2 among visitors staying ≥ 30 minutes, identified COVID-19 cases in < 0.01% (6/72 605) of hospital visitors to a large hospital campus over an 8-week study period. The potential for nosocomial transmission of SARS-CoV-2 from hospital visitors was thus very low, and could be further mitigated by universal mask-wearing among staff and visitors.

ABSTRACT Immunocompromised hosts with prolonged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have been implicated in the emergence of highly mutated SARS-CoV-2 variants. Spike mutations are of particular concern because the spike protein is a key target for vaccines and therapeutics for SARS-CoV-2. Here, we report the emergence of spike mutations in two immunocompromised patients with persistent SARS-CoV-2 reverse transcription (RT)-PCR positivity (>90 days). Whole-genome sequence analysis of samples obtained before and after coronavirus disease 2019 (COVID-19) treatment demonstrated the development of partial therapeutic escape mutations and increased intrahost SARS-CoV-2 genome diversity over time. This case series thus adds to the accumulating evidence that immunocompromised hosts with persistent infections are important sources of SARS-CoV-2 genome diversity and, in particular, clinically important spike protein diversity. IMPORTANCE The emergence of clinically important mutations described in this report highlights the need for sustained vigilance and containment measures when managing immunocompromised patients with persistent COVID-19. Even as jurisdictions across the globe start lifting pandemic control measures, immunocompromised patients with persistent COVID-19 constitute a unique group that requires close genomic monitoring and enhanced infection control measures, to ensure early detection and containment of mutations and variants of therapeutic and public health importance.

Abstract Background Empathy is pivotal to effective clinical care. Yet, the art of nurturing and assessing empathy in medical schools is rarely consistent and poorly studied. To inform future design of programs aimed at nurturing empathy in medical students and doctors, a review is proposed. Methods This systematic scoping review (SSR) employs a novel approach called the Systematic Evidence Based Approach (SEBA) to enhance the reproducibility and transparency of the process. This 6-stage SSR in SEBA involved three teams of independent researchers who reviewed eight bibliographic and grey literature databases and performed concurrent thematic and content analysis to evaluate the data. Results In total, 24429 abstracts were identified, 1188 reviewed, and 136 included for analysis. Thematic and content analysis revealed five similar themes/categories. These comprised the 1) definition of empathy, 2) approaches to nurturing empathy, 3) methods to assessing empathy, 4) outcome measures, and 5) enablers/barriers to a successful curriculum. Conclusions Nurturing empathy in medicine occurs in stages, thus underlining the need for it to be integrated into a formal program built around a spiralled curriculum. We forward a framework built upon these stages and focus attention on effective assessments at each stage of the program. Tellingly, there is also a clear need to consider the link between nurturing empathy and one’s professional identity formation. This foregrounds the need for more effective tools to assess empathy and to better understand their role in longitudinal and portfolio based learning programs.

Phenomenon Medical Student Portfolios (MSP)s allow medical students to reflect and better appreciate their clinical, research and academic experiences which promotes their individual personal and professional development. However, differences in adoption rate, content design and practice setting create significant variability in their employ. With MSPs increasingly used to evaluate professional competencies and the student's professional identity formation (PIF), this has become an area of concern. Approach We adopt Krishna’s Systematic Evidence-Based Approach to carry out a Systematic Scoping Review (SSR in SEBA) on MSPs. The structured search process of six databases, concurrent use of thematic and content analysis in the Split Approach and comparisons of the themes and categories with the tabulated summaries of included articles in the Jigsaw Perspective and Funnelling Process offers enhanced transparency and reproducibility to this review. Findings The research team retrieved 14501 abstracts, reviewed 779 full-text articles and included 96 articles. Similarities between the themes, categories and tabulated summaries allowed the identification of the following funnelled domains: Purpose of MSPs, Content and structure of MSPs, Strengths and limitations of MSPs, Methods to improve MSPs, and Use of E-portfolios. Insights Variability in the employ of MSPs arise as a result of a failure to recognise its different roles and uses. Here we propose additional roles of MSPs, in particular, building on a consistent set of content materials and assessments of milestones called micro-competencies. Whislt generalised micro-competencies assess achievement of general milestones expected of all medical students, personalised micro-competencies record attainment of particular skills, knowledge and attitudes balanced against the medical student’s abilities, context and needs. This combination of micro-competencies in a consistent framework promises a holistic, authentic and longitudinal perspective of the medical student’s development and maturing PIF.

Summary: Background: Comprehensive characterization of exposures and immune responses to viral infections is critical to a basic understanding of human health and disease. We previously developed the VirScan system, a programmable phage-display technology for profiling antibody binding to a library of peptides designed to span the human virome. Previous VirScan analytical approaches did not carefully account for antibody cross-reactivity among sequences shared by related viruses or for the disproportionate representation of individual viruses in the library. Methods: Here we present the AntiViral Antibody Response Deconvolution Algorithm (AVARDA), a multi-module software package for analyzing VirScan datasets. AVARDA provides a probabilistic assessment of infection with species-level resolution by considering sequence alignment of all library peptides to each other and to all human viruses. We employed AVARDA to analyze VirScan data from a cohort of encephalitis patients with either known viral infections or undiagnosed etiologies. We further assessed AVARDA's utility in associating viral infection with type 1 diabetes and lupus. Findings: By comparing acute and convalescent sera, AVARDA successfully confirmed or detected encephalitis-associated responses to human herpesviruses 1, 3, 4, 5, and 6, improving the rate of diagnosing viral encephalitis in this cohort by 44%. AVARDA analyses of VirScan data from the type 1 diabetes and lupus cohorts implicated enterovirus and herpesvirus infections, respectively. Interpretation: AVARDA, in combination with VirScan and other pan-pathogen serological techniques, is likely to find broad utility in the epidemiology and diagnosis of infectious diseases. Funding: This work was made possible by support from the National Institutes of Health (NIH), the US Army Research Office, the Singapore Infectious Diseases Initiative (SIDI), the Singapore Ministry of Health's National Medical Research Council (NMRC) and the Singapore National Research Foundation (NRF).

Background: Prolonged shedding/relapse of COVID-19 infection has been reported, particularly in patients who received anti-CD20 agents (eg. rituximab). However, cases of occult COVID-19, in which SARS-CoV-2 persistence in lung parenchyma is diagnosed despite clearance from nasopharyngeal (NP) specimens, are uncommon. Case summary: We describe two cases of occult COVID-19 in immunocompromised patients. Both patients had received rituximab previously. Both cases initially presented as ground-glass infiltrates on lung imaging; the diagnosis was originally not suspected due to repeated demonstration of negative SARS-CoV-2 from NP specimens, and alternative etiologies were originally considered. Persistence of SARS-CoV-2 in lung parenchyma, however, was demonstrated on bronchoalveolar lavage (BAL) specimens; additionally, isolation of viable SARS-CoV-2 virus and detection of SARS-CoV-2 nucleocapsid and spike-protein antigen in lung tissue on immunohistochemistry close to 3-months from primary infection strongly suggested ongoing viral persistence and replication as a driver of the lung parenchymal changes, which resolved after antiviral treatment. Discussion: Occult COVID-19 can be a cause of unexplained ground-glass infiltrates on lung imaging; negative NP samples do not rule out SARS-CoV-2 persistence and invasive sampling must be considered. The unsuspected presence of viable virus on BAL, however, highlights that procedurists perfoming aerosol-generating-procedures during an ongoing pandemic wave must also practise appropriate infection-prevention precautions to limit potential exposure.

Background: Heralded as a teaching, assessment and reflective tool, and increasingly as a longitudinal and holistic perspective of the educator’s development, medical educator’s portfolios (MEP)s are increasingly employed to evaluate progress, assess for promotions and career switches, used as a reflective tool and as a means of curating educational activities. However, despite its blossoming role, there is significant dissonance in the content and structure of MEPs. As such, a systematic scoping review (SSR) is proposed to identify what is known of MEPs and its contents. Methods: Krishna’s Systematic Evidenced Based Approach (SEBA) was adopted to structure this SSR in SEBA of MEPs. SEBA’s constructivist approach and relativist lens allow data from a variety of sources to be considered to paint a holistic picture of available information on MEPs. Results: From the 12 360 abstracts reviewed, 768 full text articles were evaluated, and 79 articles were included. Concurrent thematic and content analysis revealed similar themes and categories including: (1) Definition and Functions of MEPs , (2) Implementing and Assessing MEPs , (3) Strengths and limitations of MEPs and (4) electronic MEPs . Discussion: This SSR in SEBA proffers a novel 5-staged evidence-based approach to constructing MEPs which allows for consistent application and assessment of MEPs. This 5-stage approach pivots on assessing and verifying the achievement of developmental milestones or ‘micro-competencies’ that facilitate micro-credentialling and effective evaluation of a medical educator’s development and entrust-ability. This allows MEPs to be used as a reflective and collaborative tool and a basis for career planning.

Aim The long-term stress, anxiety and job burnout experienced by healthcare workers (HCWs) are important to consider as the novel coronavirus disease (COVID-19) pandemic stresses healthcare systems globally. The primary objective was to examine the changes in the proportion of HCWs reporting stress, anxiety, and job burnout over six months during the peak of the pandemic in Singapore. The secondary objective was to examine the extent that objective job characteristics, HCW-perceived job factors, and HCW personal resources were associated with stress, anxiety, and job burnout. Method A sample of HCWs (doctors, nurses, allied health professionals, administrative and operations staff; N = 2744) was recruited via invitation to participate in an online survey from four tertiary hospitals. Data were gathered between March-August 2020, which included a 2-month lockdown period. HCWs completed monthly web-based self-reported assessments of stress (Perceived Stress Scale-4), anxiety (Generalized Anxiety Disorder-7), and job burnout (Physician Work Life Scale). Results The majority of the sample consisted of female HCWs (81%) and nurses (60%). Using random-intercept logistic regression models, elevated perceived stress, anxiety and job burnout were reported by 33%, 13%, and 24% of the overall sample at baseline respectively. The proportion of HCWs reporting stress and job burnout increased by approximately 1·0% and 1·2% respectively per month. Anxiety did not significantly increase. Working long hours was associated with higher odds, while teamwork and feeling appreciated at work were associated with lower odds, of stress, anxiety, and job burnout. Conclusions Perceived stress and job burnout showed a mild increase over six months, even after exiting the lockdown. Teamwork and feeling appreciated at work were protective and are targets for developing organizational interventions to mitigate expected poor outcomes among frontline HCWs.

Background: Medical professionalism enhances doctor-patient relationships and advances patient-centric care. However, despite its pivotal role, the concept of medical professionalism remains diversely understood, taught and thus poorly assessed with Singapore lacking a linguistically sensitive, context specific and culturally appropriate assessment tool. A scoping review of assessments of professionalism in medicine was thus carried out to better guide its understanding. Methods: Arksey and O’Malley’s (2005) approach to scoping reviews was used to identify appropriate publications featured in four databases published between 1 January 1990 and 31 December 2018. Seven members of the research team employed thematic analysis to evaluate the selected articles. Results: 3799 abstracts were identified, 138 full-text articles reviewed and 74 studies included. The two themes identified were the context-specific nature of assessments and competency-based stages in medical professionalism. Conclusions: Prevailing assessments of professionalism in medicine must contend with differences in setting, context and levels of professional development as these explicate variances found in existing assessment criteria and approaches. However, acknowledging the significance of context-specific competency-based stages in medical professionalism will allow the forwarding of guiding principles to aid the design of a culturally-sensitive and practical approach to assessing professionalism.

The COVID-19 pandemic has presented significant challenges for medical schools. It is critical to ensure final year medical school students are not delayed in their entry to the clinical workforce in times of healthcare crisis. However, proceeding with assessment to determine competency for graduation from medical school, and maintaining performance standards for graduating doctors is an unprecedented challenge under pandemic conditions. This challenge is hitherto uncharted territory for medical schools and there is scant guidance for medical educators. In early March 2020, Duke-National University Singapore Medical School embraced the challenge for ensuring competent final year medical students could complete their final year of studies and graduate on time, to enter the medical workforce in Singapore without delay. This paper provides details of how the final year clinical performance examinations were planned and conducted during the COVID-19 pandemic. The aim of the paper is to provide guidance to other medical schools in similar circumstances who need to plan and make suitable adjustments to clinical skills examinations under current pandemic conditions. The paper illustrates how it is possible to design and implement clinical skills examinations (OSCEs) to ensure the validity and reliability of high-stakes performance assessments whilst protecting the safety of all participants, minimising risk and maintaining defensibility to key stakeholders.

Infectious diseases (ID) specialists advise on complicated infections and are advocates for the interventions of antibiotic stewardship programs (ASP). Early referral to ID specialists has been shown to improve patient outcomes; however, not all referrals to ID specialists are made in a timely fashion. A retrospective cross-sectional study of all referrals to ID specialists in a Singaporean tertiary hospital was conducted from January 2016 to January 2018. The following quality indicators were examined: early referral to ID specialists (within 48 h of admission) and ASP intervention for inappropriate antibiotic usage, even after referral to ID specialists. Chi-square was used for univariate analysis and logistic regression for multivariate analysis. A total of 6490 referrals over the 2-year period were analysed; of those, 36.7% (2384/6490) were from surgical disciplines, 47.0% (3050/6490) were from medical disciplines, 14.2% (922/6490) from haematology/oncology and 2.1% (134/6490) were made to the transplant ID service. Haematology/oncology patients and older patients (aged ≥ 60 years) had lower odds of early referral to ID specialists but higher odds of subsequent ASP intervention for inappropriate antibiotic usage, despite prior referral to an ID specialist. Elderly patients and haematology/oncology patients can be referred to ID specialists earlier and their antimicrobial regimens further optimised, perhaps by fostering closer cooperation between ID specialists and primary physicians.

UNLABELLED:CELADEN was a randomized placebo-controlled trial of 50 patients with confirmed dengue fever to evaluate the efficacy and safety of celgosivir (A study registered at ClinicalTrials.gov, number NCT01619969). Celgosivir was given as a 400 mg loading dose and 200 mg bid (twice a day) over 5 days. Replication competent virus was measured by plaque assay and compared to reverse transcription quantitative PCR (qPCR) of viral RNA. Pharmacokinetics (PK) correlations with viremia, immunological profiling, next generation sequence (NGS) analysis and hematological data were evaluated as exploratory endpoints here to identify possible signals of pharmacological activity. Viremia by plaque assay strongly correlated with qPCR during the first four days. Immunological profiling demonstrated a qualitative shift in T helper cell profile during the course of infection. NGS analysis did not reveal any prominent signature that could be associated with drug treatment; however the phylogenetic spread of patients' isolates underlines the importance of strain variability that may potentially confound interpretation of dengue drug trials conducted during different outbreaks and in different countries. Celgosivir rapidly converted to castanospermine (Cast) with mean peak and trough concentrations of 5727 ng/mL (30.2 μM) and 430 ng/mL (2.3 μM), respectively and cleared with a half-life of 2.5 (± 0.6) hr. Mean viral log reduction between day 2 and 4 (VLR2-4) was significantly greater in secondary dengue than primary dengue (p = 0.002). VLR2-4 did not correlate with drug AUC but showed a trend of greater response with increasing Cmin. PK modeling identified dosing regimens predicted to achieve 2.4 to 4.5 times higher Cmin. than in the CELADEN trial for only 13% to 33% increase in overall dose. A small, non-statistical trend towards better outcome on platelet nadir and difference between maximum and minimum hematocrit was observed in celgosivir-treated patients with secondary dengue infection. Optimization of the dosing regimen and patient stratification may enhance the ability of a clinical trial to demonstrate celgosivir activity in treating dengue fever based on hematological endpoints. A new clinical trial with a revised dosing regimen is slated to start in 2016 (NCT02569827). Furthermore celgosivir's potential value for treatment of other flaviruses such as Zika virus should be investigated urgently. TRIAL REGISTRATION:ClinicalTrials.gov NCT01619969.

Rabies is one of the most feared human diseases as it is almost uniformly fatal once clinical symptoms set in. The majority of deaths were due to a lack of rabies post-exposure prophylaxis (PEP). We review the profile of travellers to Southeast Asia (SEA) seeking rabies PEP in Singapore General Hospital (SGH). Thirty-seven patients visited our travel clinic for rabies PEP from Dec 2010 to Dec 2013. Their mean age was 27.0 years. Twenty-four (65%) received rabies PEP within 24 hours of exposure. Rabies immunoglobulin (RIG) was indicated in 28 cases (76%) but only half were administered; two-thirds were given in our clinic. Only two received rabies pre-exposure prophylaxis and both were non-residents. There is an urgent need to increase the awareness of potential rabies infection amongst Asian travellers.

The prevalence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections is increasing globally and in Singapore. Skin and soft tissue infections (SSTIs) are the most common manifestations, ranging from common furuncles to the rare but life-threatening necrotizing fasciitis. Surgical drainage and debridement where feasible are the mainstay of therapy, whereas MRSA-active antibiotics are essential when surgery is not possible or as adjunctive therapy for severe and/or complicated SSTIs. In itself, the continued inexorable rise in CA-MRSA rates poses difficult challenges for primary healthcare and hospital infection control. Innovative approaches are required to mitigate its impact in both the community and hospital settings.

Introduction: Nurturing professional identities instils behavioural standards of physicians, and this in turn facilitates consistent professional attitudes, practice and patient care. Identities are socioculturally constructed efforts; therefore, we must account for the social, cultural and local healthcare factors that shape physicians' roles, responsibilities and expectations. This study aimed to forward a programme to nurture professionalism among physicians in Singapore. Methods: A three-phase, evidenced-based approach was used. First, a systematic scoping review (SSR) was conducted to identify professionalism elements. Second, a questionnaire was created based on the findings of the SSR. Third, a modified Delphi approach, which involved local experts to identify socioculturally appropriate elements to nurture professionalism, was used. Results: A total of 124 articles were identified from the SSR; these articles revealed definitions, knowledge, skills and approaches to nurturing professionalism. Through the modified Delphi approach, we identified professional traits, virtues, communication, ethical, self-care, teaching and assessment methods, and support mechanisms. Conclusion: The results of this study formed the basis for a holistic and longitudinal programme focused on instilling professional traits and competencies over time through personalised and holistic support of physicians. The findings will be of interest to medical communities in the region and beyond. [ABSTRACT FROM AUTHOR]
