Article Synopsis
  • The study explores how the HPV8 virus interacts with skin keratinocyte stem cells (KSCs), particularly how it influences KSC proliferation and viral transmission.
  • HPV8's E6 gene specifically targets and activates certain KSCs, leading to their expansion and potential vulnerability to cancer caused by sun exposure.
  • The findings suggest that HPV8 may play a critical role in the development of actinic keratosis, a skin condition linked to increased cancer risk, by manipulating KSCs without permanently integrating into their genetic material.

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.

Background: Portfolios are increasingly commonplace in postgraduate medical education. However, poor understanding of and variations in their content, quality, and structure have hindered their use across different settings, thus dampening their efficacy.

Methods: This systematic scoping review on portfolios in postgraduate medical education utilized Krishna's Systematic Evidence Based Approach (SEBA).

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.

Introduction: Supplementary ultrasound surveillance in breast cancer patients can detect additional cancers but is associated with unnecessary biopsies and follow-ups. We aim to determine, in patients with ductal carcinoma in situ (DCIS), the prevalence and factors associated with second breast cancers and the usefulness of supplementary ultrasound surveillance. This is the first study which focused on the usefulness of ultrasound surveillance in DCIS patients.

Objectives: To develop a paediatric radiology themed escape room session for undergraduate education and secondly, to determine participant satisfaction and improvement in knowledge.

Methods: A paediatric radiology escape room with accompanying tutorial was developed around key learning objectives set within the RCR and ESR undergraduate curriculum. Students were recruited from two different universities and undertook the escape room themed teaching.

Introduction: This study aimed to evaluate compliance with and performance of the Canadian Computed Tomography Head Rule (CCHR), and its applicability to the Singapore adult population with minor head injury.

Methods: We conducted a retrospective study over six months of consecutive patients who presented to the adult emergency department (ED) with minor head injury. Data on predictor variables indicated in the CCHR was collected and compliance with the CCHR was assessed by comparing the recommendations for head computed tomography (CT) to its actual usage.

Despite high vaccination coverage, pertussis remains an important respiratory infectious disease and the least-controlled vaccine-preventable infectious disease in children. Natural infection with Bordetella pertussis is known to induce strong and long-lasting immunity that wanes later than vaccine-mediated immunity. Therefore, a live attenuated B.

Whereas the great majority of the current vaccines are delivered through the parenteral route, mucosal administration has been increasingly considered for controlling infection and preventing disease. Mucosal vaccination can trigger both humoral and cell-mediated protection, not only at the targeted mucosal surface, but also systemically. In this regard, nasal vaccination has shown great potential.

The attenuated Bordetella pertussis BPZE1 vaccine strain represents an attractive platform for the delivery of heterologous vaccine candidates via the nasal route. The filamentous hemagglutinin (FHA) has been used to secrete or expose the foreign antigens at the bacterial surface. In this study, one, two and three copies of the Cys-containing ectodomain of matrix protein 2 (M2e) from influenza A virus were genetically fused to full length FHA and expressed in BPZE1.

The threat of a pandemic spread of highly virulent influenza A viruses currently represents a top global public health problem. Mass vaccination remains the most effective way to combat influenza virus. However, current vaccination strategies face the challenge to meet the demands in a pandemic situation.
