RESUMEN

Deaths from non-melanoma skin cancers (NMSCs) have almost doubled in Australia in recent years. Cutaneous squamous cell carcinoma (cSCC) constitutes approximately 20% of NMSCs, but is responsible for most of the deaths. Most skin cancers are easy to diagnose and treat and therefore cSCC are often trivialised; however, there is a high-risk subgroup of cSCC (HRcSCC) that is associated with a high risk of metastasis and death. The definition of early HRcSCC and our ability to identify them is evolving. Many significant prognostic factors have been identified, but a universally accepted prognostic index does not exist. Guidelines for workup, treatment, and follow-up leave many important decisions open to broad interpretation by the treating physician or multidisciplinary team. Some of the treatments used for metastatic cSCC are not supported by robust evidence and the prognosis of metastatic cSCC is guarded. In this review, we highlight the rapid rise in NMSC deaths and discuss some of the deficiencies in our knowledge of how to define, diagnose, stage, and manage HRcSCC.

RESUMEN

BACKGROUND: Increasingly, health services are adopting short-term consultative therapy models, such as single session therapy, to cope with increased service demands, finite budgets and changing consumer expectations. Within the paediatric sub-specialty of child development and behaviour, allied health clinicians are central to supporting families to understand their children, provide therapeutic interventions and help achieve optimal developmental and health outcomes. This study aimed to describe parents'/caregivers' engagement during advanced allied health consultations utilizing a single session therapy framework for managing neurodevelopmental and behavioural concerns in children. METHODS: Between March to June 2021, 14 parents participated in a qualitative study involving focus groups. Reflexive thematic analysis was used to code and interpret the data to understand and explore families' engagement in single session therapy. RESULTS: Three overarching themes relating to parents' engagement during consultations emerged from the data: connection with the clinician, parental attributes and organizational influences. Clinician connection was the prominent construct that enhanced parent attributes and the positive perception of the organization in an ongoing manner. There was a complex interplay between the behavioural and affective components of the clinician, parents and the organization to create mutual presence, valued time, understanding and action. CONCLUSIONS: This study demonstrates the importance of clinician connection, parental attributes and organizational influences to enhance engagement in therapeutic consultations. These factors are interrelated and are a complex blend of behaviour and internal states and highly individualized for each family. Understanding how services can continue to engage families is integral to ongoing sustainability and overall health and well-being.

RESUMEN

BACKGROUND AND OBJECTIVES: Securing an adequate blood supply relies on accurate knowledge of blood donors and donation practices. As published evidence on Asian populations is sparse, this study aims to gather up-to-date information on blood donors and donation practices in Asia to assist planning and strategy development. MATERIALS AND METHODS: Ten blood collection agencies (BCAs) provided 12 months' data on donors who met eligibility criteria or were deferred, as well as details of their donation practices. Body mass index and blood volumes were calculated and analysed. RESULTS: Data on 9,599,613 donations and 154,834 deferrals from six national and four regional BCAs revealed varied donation eligibility and collection practices. Seven used haemoglobin (Hb) criteria below the World Health Organization anaemia threshold. Seven accepted donors weighing <50 kg. Data collection on the weight and height of donors and on deferrals was inconsistent, often not routine. Deferred donors appear to weigh less, with corresponding lower estimated blood volume. CONCLUSION: The diversity in eligibility criteria and donation practices reflects each BCA's strategy for balancing donor health with securing an adequate blood supply. Use of lower Hb criteria substantiate their appropriateness in Asia and indicate the need to define Hb reference intervals relevant to each population. We encourage routine gathering of donor weight and height data to enable blood volume estimation and local optimization of donation volumes. Blood volume estimation formulae specific for the Asian phenotype is needed. Information from this study would be useful for tailoring donation criteria of Asian donors around the world.

RESUMEN

BACKGROUND: Case-Based Learning (CBL) in medical education is a teaching approach that engages students as learners through active learning in small, collaborative groups to solve cases from clinical patients. Due to the challenges afforded by the COVID-19 pandemic, small group learning such as CBL, transitioned quickly to include technology-enhanced learning to enable distance delivery, with little information on how to apply pedagogical frameworks and use learning theories to design and deliver online content. METHODS: To extend understanding of online CBL a scoping review protocol following the PRISMA-ScR framework explored the literature that describes the use of online CBL application in medical education and the outcomes, perceptions, and learning theories. A literature search was conducted in January 2022 followed by a subsequent review in October 2022. After peer review using the PRESS guidelines, the CASP appraisal tool was used to assess the rigor of each study design. RESULTS: The scoping review identified literature published between 2010 and 2022 (n = 13 articles), on online CBL in the field of medical education with 11 observational studies describing student and facilitator perceptions and two randomized controlled studies. Positive perceptions of online learning included a flexible work-life balance, connection with learners, and improved accessibility. Negative experiences of online CBL included poor internet access, a distracting learning environment, and loss of communication. In the studies that collected student performance data, results showed equivalent or improved outcomes compared to the control. The CASP appraisal tool highlighted the deficiencies in most study designs, lack of framework or learning theory, and poor reproducibility of the methods to answer the research questions. CONCLUSION: This scoping review identified literature to describe the academic outcomes, and student and facilitator perceptions of online CBL in medical education. However, the CASP tool uncovered deficiencies in study descriptions and design leading to poor quality evidence in this area. The authors provide recommendations for frameworks and learning theories for the future implementation of online CBL.

RESUMEN

The World Health Organization estimates that the world's population over 60 years of age will nearly double in the next 30 years. This change imposes increasing demands on health and social services with increased disease burden in older people, hereafter defined as people aged 60 years or more. An older population will have a greater incidence of cardiovascular disease partly due to higher levels of blood fibrinogen, increased levels of some coagulation factors, and increased platelet activity. These factors lead to a hypercoagulable state which can alter haemostasis, causing an imbalance in appropriate coagulation, which plays a crucial role in the development of cardiovascular diseases. These changes in haemostasis are not only affected by age but also by gender and the effects of hormones, or lack thereof in menopause for older females, ethnicity, other comorbidities, medication interactions, and overall health as we age. Another confounding factor is how we measure fibrinogen and coagulation through laboratory and point-of-care testing and how our decision-making on disease and treatment (including anticoagulation) is managed. It is known throughout life that in normal healthy individuals the levels of fibrinogen and coagulation factors change, however, reference intervals to guide diagnosis and management are based on only two life stages, paediatric, and adult ranges. There are no specific diagnostic guidelines based on reference intervals for an older population. How ageing relates to alterations in haemostasis and the impact of the disease will be discussed in this chapter. Along with the effect of anticoagulation, laboratory testing of fibrinogen and coagulation, future directions, and implications will be presented.

RESUMEN

BACKGROUND: Human pathophysiology is important in undergraduate nursing education to help students develop clinical reasoning skills. Traditionally pathophysiology education in undergraduate nursing is taught face-to-face. However, eLearning in nursing curricula may provide flexible delivery options. OBJECTIVE: With increased inclusion of technology enhanced learning in nursing curricula, a hematology eLearning module was evaluated in a pathophysiology subject to determine whether it was comparable to face-to-face learning. DESIGN: Single-blind randomized pre-test/post-test controlled trial. SETTING: School of Health and Behavioural Sciences, University of the Sunshine Coast. PARTICIPANTS: A total of 271 second-year undergraduate students enrolled in Human Pathophysiology were included in the study. Students were from three bachelor programs: Nursing Science; Paramedic Science; and Clinical Exercise Physiology. Students were randomly allocated to either the experimental group (n = 85) or the control group (n = 186). METHODS: A hematology eLearning module was designed to be self-directed and learner-centered, guided by constructivist learning theories for delivery in the human pathophysiology subject. The experimental "eLearning" group completed the module independently, and the control "face-to-face" group completed equivalent paper-based activities facilitated by a tutor. All students completed a pre-test assessment and two post-test assessments two weeks after the intervention and at the end of the subject. RESULTS: There was no significant difference in assessment scores between the experimental and control groups, or between nursing and other programs. CONCLUSION: eLearning was comparable to face-to-face teaching in this study. We recommend further research to strengthen the links between pathophysiology theory to clinical reasoning skills using eLearning.

RESUMEN

OBJECTIVES: To investigate the blood supply contribution of older donors in five Asia Pacific regions. BACKGROUND: Older people are often the largest blood user group. Thus, as the population ages blood supply needs increase. Minimum and maximum donation age criteria potentially constrain the size of the donor pool. MATERIALS AND METHODS: Haemoglobin values and demographic frequency analytics (sex, age and blood type) were analysed on blood donors aged 60 years or more, from Hong Kong, Indonesia, Japan, Singapore and South Korea over 12 months. RESULTS: Data on 434357 donations was analysed. ABO Rh(D) frequencies of older donors matched that of national frequencies. Older donors were a disproportionately smaller proportion of the total donor pool for each country. Indonesia was the only region with no maximum age limit. Median haemoglobin for older males ranged from 14.2 to 14.8 g/dl and for females 13.1 to 13.9 g/dl. The frequency of female donors was between 15% and 33% of older donors. Older donors had higher donation frequency and lower deferral rates. CONCLUSION: Older donors are loyal and regular donors but under-represented in all regions studied. They could help meet future blood supply needs, especially post-menopausal female donors. Studies including ferritin levels are needed to determine if upper age limits can be safely modified.

RESUMEN

The impact of the Covid-19 pandemic has presented challenges in medical education particularly, with development of online learning in a short time period. Notably there has been a significant increase in the use of digital technology applications to meet this challenge. For instance, in the first quarter of 2020 the game-based software Kahoot! reported a threefold increase in players and a fivefold increase in asynchronous learning globally. However, there is limited research into the use of game-based digital technology applications such as Kahoot! and the associated learning theories, particularly in histology, anatomy, and medical education. This scoping review explored the utilization, outcome scores, and student perceptions of learning with the application of Kahoot! in histology, anatomy, and medical education. Online databases were used to identify articles published between 2013 and 2021 from which 12 articles were included in the review. The majority of articles supported positive student outcomes including improved collaborative learning, improved knowledge of content, attendance, and participation. Minor negative aspects included increased time on task, overwhelming learning content, and distractions due to gadgets. None of the articles included a control group. The main educational theories identified were active learning followed by social and constructivism learning theory. In light of the Covid-19 pandemic a rapid and fundamental shift in how digital applications are being used in educational institutions has evolved. Further research on learning frameworks and studies with control groups is required to evaluate Kahoot! as a potentially valuable online application in histology, anatomy, and medical education.

RESUMEN

BACKGROUND: Benchmarking across and within universities is a common tool to evaluate performance of a program and maintain accreditation requirements. While teaching remains a primary responsibility of many academics, academic research performance is a major contributor towards career advancement and standards in the medical laboratory science profession. While anecdotal evidence suggests academics are active contributors to the evidence base of the profession, there is a high variability in research output in relation to institution and level of appointment. The aim of the study was to benchmark the research track record of Australian medical laboratory science academics and provide insight into how research productivity informs the level of appointment of academics across their career pathway. METHODS: A bibliographic analysis of Australian medical laboratory science faculty websites and corresponding Scopus citation database profiles was conducted. A description of current research track record and relationships with holding a doctorate, academic appointment level, research and teaching interests, and institutional characteristics were explored. Quantitative data and frequencies were analysed using IBM SPSS version 26 to benchmark research track records by academic appointment level. RESULTS: There were 124 academics identified from 13 universities who had a teaching and research position in an undergraduate medical laboratory science program in Australia. Academics at the level of lecturer or higher typically held a doctorate (89%). Holding a doctorate strongly influenced the number of publications. The top 20% of researchers authored around half of the overall publications. The majority of academics did not have alignment of their major research and teaching areas however, alignment had no influence on number of publications. There was, however, an inconsistent relationship between metropolitan or regional university location and the number of publications. CONCLUSION: Data from this study provides academics with benchmarks for the research track record required at each level of appointment. When drawing conclusions on academic progression, promotion and tenure through research track record it would be mindful to assess each on a case by case basis. Institution (metropolitan versus regional) and research interest appears to influence publication number, h-index and citation scores.

RESUMEN

Reference intervals are vital for interpreting coagulation results. Current interval ranges have no upper age limit, although there is evidence that coagulation function changes with age. This study compared coagulation results from healthy people aged >60 years against adult reference intervals for routine clotting assays and thromboelastography (TEG) to determine if reference intervals are relevant to older adults.Samples from healthy blood donors aged >60 years (n=30 male, n=30 female) were tested by TEG® 6s, prothrombin time (PT), activated partial thromboplastin time (aPTT), and derived fibrinogen.All older donor-derived fibrinogen results were within the adult reference intervals, however levels were significantly higher in females. A proportion of TEG® 6s and aPTT results were not within the reference intervals. As populations around the world live longer, these findings question whether older adults require age specific coagulation reference intervals.

RESUMEN

Abdominal aortic aneurysm (AAA) is a vascular disease involving permanent focal dilation of the abdominal aorta (≥30 mm) that can lead to catastrophic rupture. Destructive remodeling of aortic connective tissue in AAA contributes to wall stiffening, a mechanical parameter of the arterial system linked to a heightened risk of cardiovascular morbidity and mortality. Since aortic stiffening is associated with AAA progression, treatment options that target vascular inflammation would appear prudent. Given this, and growing evidence indicating robust anti-inflammatory and vasoprotective properties for long chain omega-3 polyunsaturated fatty acids (LC n-3 PUFAs), this study evaluated the impact of these nutrients (1.8 g/day for 12 weeks) on indices of vascular stiffness in patients with AAA. At baseline, pulse wave velocity (PWV) and augmentation index normalized to a heart rate of 75 bpm (AIx75) were significantly higher in patients with AAA compared to control participants (PWV: 14.2 ± 0.4 m.s-1 vs. 12.6 ± 0.4 m.s-1, p = 0.014; AIx75: 26.4 ± 1.7% vs. 17.3 ± 2.7%, p = 0.005). Twelve-week LC n-3 PUFA supplementation significantly decreased PWV (baseline: 14.2 ± 0.6 m.s-1, week 12: 12.8 ± 0.7 m.s-1, p = 0.014) and heart rate (baseline: 63 ± 3 bpm, week 12: 58 ± 3 bpm, p = 0.009) in patients with AAA. No change was observed for patients receiving placebo capsules. While this raises the possibility that LC n-3 PUFAs provide improvements in aortic stiffness in patients with AAA, the clinical implications remain to be fully elucidated.

RESUMEN

Malingering mental disorder for financial compensation can offer substantial rewards to those willing to do so. A recent review of UK medico-legal experts' practices for detecting claimants evidenced that they are not well equipped to detect those that do. This is not surprising, considering that very little is known regarding why individuals opt to malinger. A potential construct which may influence an individual's choice to malinger is their knowledge of the disorder, and when one considers the high levels of depression literacy within the UK, it is imperative that this hypothesis is investigated. A brief depression knowledge scale was devised and administered to undergraduate students (N = 155) alongside a series of questions exploring how likely participants were to malinger in both workplace stress and claiming for benefit vignettes. Depression knowledge did not affect the likelihood of engaging in any malingering strategy in either the workplace stress vignettes or the benefit claimant vignettes. Differences were found between the two vignettes providing evidence for the context-specific nature of malingering, and an individual's previous mental disorder was also influential.

RESUMEN

BACKGROUND: Traditionally, the training of medical laboratory science students has taken place in the laboratory and has been led by academic and pathology experts in a face-to-face context. In recent years, budgetary pressures, increasing student enrolments and limited access to laboratory equipment have resulted in reduced staff-student contact hours in medical laboratory science education. While this restructure in resources has been challenging, it has encouraged innovation in online blended learning. METHODS: Blended learning histology lessons were implemented in a face-to-face and e-Learning format in a medical laboratory science program to teach tissue morphology and technical procedures outside of the traditional laboratory classroom. Participating students were randomly allocated to either the 'video' group (n = 14) or the 'control' group (n = 14). After all students attempted the e-Learning lessons and viewed expert-led video recordings online, students demonstrated their hands-on practical skills in the laboratory. Technical skills, demonstration of safety awareness, and use of histology equipment was captured by video through first person 'point of view' recordings for the 'video' group only. The 'control' group performed the same activities but were not recorded. Prior to summative assessment, the 'video' group students had a digital resource portfolio that enabled them to review their skills, receive captured feedback and retain a visual copy of their recorded procedure. RESULTS: Results showed that students who participated in the online video format had statistically better practical examination scores and final grades compared to the control group. CONCLUSION: Findings from this study suggest that students are engaged and motivated when being taught in a blended learning format and respond positively to the use of video recordings with expert feedback for the initial learning of hands-on techniques. For the academic, developing a blended learning medical laboratory science program, which includes annotated virtual microscopy, video demonstrations, and online interactive e-Learning activities, provides an effective and economic approach to learning and teaching.
