RESUMO

BACKGROUND: Formal leadership training is typically targeted at senior health professionals. The Healthcare Leadership Academy (HLA) was formed in 2016 to provide a leadership programme for students and early-career health professionals. This study analyses the effectiveness of the HLA scholarship programme as an intervention for improving interest in and preparing scholars for future leadership roles. METHODS: Survey data was used to assess the effectiveness of the HLA Scholarship program in cultivating leadership development. Questions required either multiple-choice, free text, ranking or Likert scale ('strongly agree', 'agree', 'neither agree nor disagree', 'disagree', 'strongly disagree) responses. Participants spanned six regions (London, Newcastle, Bristol, Belfast, Edinburgh, and Amsterdam) in four countries (England, Scotland, Northern Ireland, and the Netherlands). Descriptive statistical analyses were conducted, and insights were drawn from the open-ended survey questions using a leadership framework. RESULTS: Seventy participants who underwent the course between 2016 and 2020 completed the questionnaire. Nearly all (99%) found that the training provided on the programme had equipped them to be more effective leaders, with 86% of respondents stating that they were more likely to take on leadership roles. Nearly all (97.1%) found the course to be either of good or very good quality. Nineteen insights were identified from free text responses that fitted under one of the four themes of the leadership framework: "optimising", "resolving uncertainty", "enhancing adaptability", and "promulgating a vision". CONCLUSIONS: Healthcare leadership is a non-negotiable component of healthcare delivery in the 21st Century. As healthcare professionals, it is our duty to be effective leaders confident and competent in navigating the increasingly complex systems within which we operate for the benefit of ourselves, colleagues, and patients. By accounting for known shortcomings and developing ameliorative measures, the HLA Scholarship programme addresses unmet needs in a structured manner to support effective long-term healthcare leadership development.

RESUMO

Authoritarian governments are characterised by political systems with concentrated and centralised power. Healthcare is a critical component of any state. Given the powers of an authoritarian regime, we consider the opportunities they possess to derive good health outcomes. The 2019 Varsity Medical Ethics Debate convened on the motion: 'This house believes authoritarian government is the route to good health outcomes' with Oxford as the Proposition and Cambridge as the Opposition. This article summarises and extends key arguments made during the 11th annual debate between medical students from the Universities of Oxford and Cambridge. By contrasting the principles underlying authoritarianism and democracy, it enables a discussion into how they translate into healthcare provision and the outcomes derived. Based on the foundation of said principles, an exploration of select cases represents examples of applications and the results. We analyse the past, present and future implications on the basis of fundamental patient-centred care.

RESUMO

The peculiar nature of scientific publishing has allowed for a high degree of market concentration and a non-collusive oligopoly. The non-substitutable characteristic of scientific journals has facilitated an environment of market concentration. Acquisition of journals on a capabilities-based approach has seen market concentration increase in favor of a small group of dominant publishers. The digital era of scientific publishing has accelerated concentration. Competition laws have failed to prevent anti-competitive practices. The need for government intervention is debated. The definition of scientific publishing as a public good is evaluated to determine the need for intervention. Policy implications are suggested to increase competitiveness in the short-run and present prestige-maintaining alternatives in the long run. A fundamental change in scientific publishing is required to enable socially efficient and equitable access for wider society's benefit.

RESUMO

Chronic Pulmonary Aspergillosis (CPA) is a destructive pulmonary disease caused by a fungal infection, affecting mainly individuals with prior or concurrent pulmonary conditions. It has a global prevalence of 42 per 100,000 population, but in the US and Europe, prevalence is less than 1 per 100,000. The clinical definition of CPA is based on various factors accounting for comorbidities, clinical presentation, and duration. It may be categorized into five subtypes that the disease may evolve between over time. Based on global consensus covering the spectrum of low-resource to high-resource settings, diagnosis is a multi-factorial process that involves a combination of clinical presentation persisting over 3 months, radiological findings, positive culture growth, and serological tests. CPA remains underdiagnosed due to a lack of awareness and is often misdiagnosed due to the comorbidities present. Treatment options are limited due to a lack of research. Furthermore, associated comorbidities and drug interactions further complicate treatment plans. Follow-up throughout treatment should be based on understanding the predictors of mortality. Identification of potential relapse or resistance to antifungal therapy is crucial to limit the low long-term survival rate. Awareness surrounding this devastating disease needs to be raised further to enable earlier identification, improve understanding of patient factors associated with prognosis, and the future potential for targeted therapies. This review aims to raise awareness of this rare condition among practitioners, by providing an overview of common risk factors influencing the prevalence and incidence of the disease. We further discuss current approaches and recent advancements in CPA diagnosis and treatment.

RESUMO

Food allergies represent life-threatening diseases which are increasing in prevalence with no definitive treatments currently in place. Current treatments are no more than preventative avoidance and symptom management. Research within the field has focused on therapeutic developments to modify the immune response in allergen-specific and non-specific methods. This review of the advances made in treatments intends to cover methods such as oral immunotherapy, modified food protein vaccines as well as the use of alternative medicine. Thus, this review aims to inform and further extend discussion surrounding the potential clinical applications as well as novel routes for further research into an, as of yet, unsolved question.

RESUMO

IMPORTANCE: The mechanisms underlying the association between chronic stress and higher mortality among individuals with cancer remain incompletely understood. OBJECTIVE: To test the hypotheses that among individuals with active head and neck cancer, that higher stress-associated neural activity (ie. metabolic amygdalar activity [AmygA]) at cancer staging associates with survival. DESIGN: Retrospective cohort study. SETTING: Academic Medical Center (Massachusetts General Hospital, Boston). PARTICIPANTS: 240 patients with head and neck cancer (HNCA) who underwent 18F-FDG-PET/CT imaging as part of initial cancer staging. MEASUREMENTS: 18F-FDG uptake in the amygdala was determined by placing circular regions of interest in the right and left amygdalae and measuring the mean tracer accumulation (i.e., standardized uptake value [SUV]) in each region of interest. Amygdalar uptake was corrected for background cerebral activity (mean temporal lobe SUV). RESULTS: Among individuals with HNCA (age 59±13 years; 30% female), 67 died over a median follow-up period of 3 years (IQR: 1.7-5.1). AmygA associated with heightened bone marrow activity, leukocytosis, and C-reactive protein (P<0.05 each). In adjusted and unadjusted analyses, AmygA associated with subsequent mortality (HR [95% CI]: 1.35, [1.07-1.70], P = 0.009); the association persisted in stratified subset analyses restricted to patients with advanced cancer stage (P<0.001). Individuals within the highest tertile of AmygA experienced a 2-fold higher mortality rate compared to others (P = 0.01). The median progression-free survival was 25 months in patients with higher AmygA (upper tertile) as compared with 36.5 months in other individuals (HR for progression or death [95%CI], 1.83 [1.24-2.68], P = 0.001). CONCLUSIONS AND RELEVANCE: AmygA, quantified on routine 18F-FDG-PET/CT images obtained at cancer staging, independently and robustly predicts mortality and cancer progression among patients with HNCA. Future studies should test whether strategies that attenuate AmygA (or its downstream biological consequences) may improve cancer survival.

RESUMO

PURPOSE: Conventional photon radiation therapy (RT) for breast cancer is associated with a reduction in global longitudinal strain (GLS) and an increase in troponin, N-terminal pro hormone B-type natriuretic peptide (NT-proBNP), and incident heart failure. The cardiac radiation exposure with proton-RT is much reduced and thus may be associated with less cardiotoxicity. The objective was to test the effect of proton-RT on GLS, troponin, and NT-proBNP. METHODS AND MATERIALS: We conducted a prospective, observational, single-center study of 70 women being treated with proton-RT for breast cancer. Serial measurements of GLS, high-sensitivity troponin I, and NT-proBNP were performed at prespecified intervals (before proton-RT, 4 weeks after completion of proton-RT, and again at 2 months after proton-RT). RESULTS: The mean age of the patients was 46 ± 11 years, and the mean body mass index was 25.6 ± 5.2 kg/m2; 32% of patients had hypertension, and the mean radiation doses to the heart and the left ventricle (LV) were 0.44 Gy and 0.12 Gy, respectively. There was no change in left ventricular ejection fraction (65 ± 5 vs 66 ± 5 vs 64 ± 4%; P = .15), global GLS (-21.7 ± 2.7 vs -22.7 ± 2.3 vs -22.8 ± 2.1%; P = .24), or segmental GLS from before to after proton-RT. Similarly, there was no change in either high-sensitivity troponin or NT-proBNP with proton-RT. However, in a post hoc subset analysis, women with hypertension had a greater decrease in GLS after proton-RT compared with women without hypertension (-21.3 ± 3.5 vs -24.0 ± 2.4%; P = .006). CONCLUSIONS: Proton-RT did not affect LV function and was not associated with an increase in biomarkers. These data support the potential cardiac benefits of proton-RT compared with conventional RT.

RESUMO

With the rise of telemedicine, wearable healthcare, and the greater leverage of 'big data' for precision medicine, various challenges present themselves to organisations, physicians, and patients. Beyond the practical, financial, and clinical considerations, we must not ignore the ethical imperative for fair and just applications to improve the field of healthcare for all. Given the increasing personalisation of medicine and the role technology will play at the interface of healthcare delivery, a thorough understanding of the challenges presented is critical for future physicians who will navigate a novel environment. This article aims to explore the ethical challenges that the adoption of digital healthcare technology presents, contextualised at multiple levels. Potential solutions are suggested to initiate a discussion about the future of medicine and digital healthcare.

RESUMO

OBJECTIVES: To mitigate risk of mortality from coronavirus 2019 infection (COVID-19), the UK government recommended 'shielding' of vulnerable people through self-isolation for 12 weeks. METHODS: A retrospective cohort study using a nationally representative English primary care database comparing people aged >= 40 years who were recorded as being advised to shield using a fixed ratio of 1:1, matching to people with the same diagnoses not advised to shield (n = 77,360 per group). Time-to-death was compared using Cox regression, reporting the hazard ratio (HR) of mortality between groups. A sensitivity analysis compared exact matched cohorts (n = 24,752 shielded, n = 61,566 exact matches). RESULTS: We found a time-varying HR of mortality between groups. In the first 21 days, the mortality risk in people shielding was half those not (HR = 0.50, 95%CI:0.41-0.59. p < 0.0001). Over the remaining nine weeks, mortality risk was 54% higher in the shielded group (HR=1.54, 95%CI:1.41-1.70, p < 0.0001). Beyond the shielding period, mortality risk was over two-and-a-half times higher in the shielded group (HR=2.61, 95%CI:2.38-2.87, p < 0.0001). CONCLUSIONS: Shielding halved the risk of mortality for 21 days. Mortality risk became higher across the remainder of the shielding period, rising to two-and-a-half times greater post-shielding. Shielding may be beneficial in the next wave of COVID-19.
