RESUMEN

Effective leaders in healthcare settings create a motivating work environment, initiate changes in practice, and facilitate interdisciplinary collaboration to advance patient-centered care. Health professionals in cancer education need leadership development to meet the continued rise in cancer cases and to keep up with the rapid biomedical and technological advances in global cancer care. In addition, leadership development in cancer education supports interprofessional collaboration, optimizes patient engagement, and provides mentorship opportunities necessary for career advancement and skill development. The identified benefits from leadership development in cancer education led to the creation of an interactive pilot leadership workshop titled "Essential Skills in Cancer Education: Leadership, Leading, and Influencing Change in Cancer Education," held at the International Cancer Education Conference in October 2020. The workshop was led by global leaders in cancer education and utilized lectures, mentorship opportunities, interactive case studies, and individual learning projects to develop leadership skills in multidisciplinary oncology professionals. Fifteen attendees from diverse educational backgrounds and levels of experience participated in the virtual leadership workshop and mentorship program. Following the workshop, participants reported an increase in knowledge regarding how to use different leadership styles, initiate changes in practice, and apply leadership skills in their career development and at their institutions. The feedback received from participants through post-workshop evaluations was overall positive and demonstrated an interest for more leadership development opportunities in cancer education. This pilot workshop shows that leadership is a valuable and teachable skill that will benefit both healthcare professionals and patients in the field of cancer education.

RESUMEN

OBJECTIVE: Several reports in the literature have identified an association between cortisol levels and the presence of chronic pain in conditions such as rheumatoid arthritis, low back pain or whiplash. In contrast, few have examined the association of cortisol and pain in people with osteoarthritis (OA). The purpose of this systematic review was to verify the association between cortisol and pain in the OA population. DESIGN: The databases MEDLINE, CINAHL, EMBASE were searched systematically for human studies written in English up to December 2018. Two researchers screened titles and abstracts against predefined inclusion criteria; a third resolved discrepancies. Articles were included if they measured the cortisol levels in adults with pain in the OA population. Methodological quality was assessed using Methodological Index for non-randomized Studies (MINORS) score. RESULTS: Seven studies reporting on 415 patients were included in this review. The MINORS scale yielded mean scores of 8.6 of 16 and 17.5 of 24, for the cohort and case-control studies respectively. In general, the studies were of poor quality. A discrepancy of noteworthy associations between cortisol level comparison and pain was found. CONCLUSIONS: This study shows that there is a discrepancy in the relationship between cortisol and pain dependent on how and when cortisol is measured. Evidence from three low-quality studies suggest increased cortisol levels in patients with pain but the conclusions have a high risk of bias. It was not possible to make a quantitative analysis comparing the relationship between cortisol and pain in the OA population.

RESUMEN

Ecological engineering principles are increasingly being applied to develop multifunctional artificial structures or rehabilitated habitats in coastal areas. Ecological engineering initiatives are primarily driven by marine scientists and coastal managers, but often the views of key user groups, which can strongly influence the success of projects, are not considered. We used an online survey and participatory mapping exercise to investigate differences in priority goals, sites and attitudes towards ecological engineering between marine scientists and coastal managers as compared to other stakeholders. The surveys were conducted across three Australian cities that varied in their level of urbanisation and environmental pressures. We tested the hypotheses that, relative to other stakeholders, marine scientists and coastal managers will: 1) be more supportive of ecological engineering; 2) be more likely to agree that enhancement of biodiversity and remediation of pollution are key priorities for ecological engineering; and 3) identify different priority areas and infrastructure or degraded habitats for ecological engineering. We also tested the hypothesis that 4) perceptions of ecological engineering would vary among locations, due to environmental and socio-economic differences. In all three harbours, marine scientists and coastal managers were more supportive of ecological engineering than other users. There was also greater support for ecological engineering in Sydney and Melbourne than Hobart. Most people identified transport infrastructure, in busy transport hubs (i.e. Circular Quay in Sydney, the Port in Melbourne and the Waterfront in Hobart) as priorities for ecological engineering, irrespective of their stakeholder group or location. There were, however, significant differences among locations in what people perceive as the key priorities for ecological engineering (i.e. biodiversity in Sydney and Melbourne vs. pollution in Hobart). Greater consideration of these location-specific differences is essential for effective management of artificial structures and rehabilitated habitats in urban embayments.

RESUMEN

BACKGROUND: Junctional (flat) naevi predominate on the extremities, whereas dermal (raised) naevi are found primarily on the head, neck and trunk. Few studies have investigated the anatomical site prevalence of melanocytic naevi categorized using dermoscopy. OBJECTIVES: To identify the prevalence of dermoscopic patterns and structures of naevi from the back and legs of adolescents. METHODS: Dermoscopic images of acquired melanocytic naevi were obtained from the back and legs of students from a population-based cohort in Framingham, Massachusetts. Naevi were classified into reticular, globular, homogeneous or complex dermoscopic patterns. Multinomial logistic regression modelling assessed the associations between dermoscopic pattern and anatomical location. RESULTS: In total 509 participants (mean age 14 years) contributed 2320 back naevi and 637 leg naevi. Compared with homogeneous naevi, globular and complex naevi were more commonly observed on the back than the legs [odds ratio (OR) 29·39, 95% confidence interval (CI) 9·53-90·65, P < 0·001 and OR 6·8, 95% CI 2·7-17·14, P < 0·001, respectively], whereas reticular lesions were less likely to be observed on the back than on the legs (OR 0·67, 95% CI 0·54-0·84, P = 0·001). Naevi containing any globules were more prevalent on the back than on the legs (25% vs. 3·6%, P < 0·001). Naevi containing any network were more prevalent on the legs than on the back (56% vs. 40·6%, P < 0·001). CONCLUSIONS: These findings add to a robust body of literature suggesting that dermoscopically defined globular and reticular naevi represent biologically distinct naevus subsets that differ in histopathological growth pattern, age- and anatomical-site-related prevalence, molecular phenotype and aetiological pathways.

RESUMEN

This paper addresses the computational modelling of a series of specific blast-related incidents and the relationships of clinical and engineering interpretations. The Royal Centre for Defence Medicine and the Defence Science and Technology Laboratory were tasked in 2010 by the UK Ministry of Defence to assist the Coroner's inquests into the 7 July 2005 London bombings. A three phase approach was taken. The first phase included an engineering expert in blast effects on structures reviewing photographs of the damaged carriages and bus to give a view on the likely physical effects on people close to the explosions. The second phase was a clinical review of the evidence by military clinicians to assess blast injury in the casualties. The third phase was to model the blast environment by structural dynamics experts to assess likely blast loading on victims to evaluate the potential blast loading on individuals. This loading information was then assessed by physiology experts. Once all teams (engineering, clinical and modelling/physiological) had separately arrived at their conclusions, the information streams were integrated to arrive at a consensus. The aim of this paper is to describe the methodology used as a potential model for others to consider if faced with a similar investigation, and to show the benefit of the transition of military knowledge to a civilian environment.

RESUMEN

OBJECTIVE: To determine country/region-specific mortality (in-hospital, 30-day and 1-year) following hip fracture across the Asia Pacific region. METHODS: Five databases MEDLINE, PUBMED, EMBASE, Web of Science and the Cochrane Library were searched to identify studies that reported mortality following hospitalisation for low-trauma hip fracture in adults aged ≥50 years with data from 2010 to 30 September 2021. There were no restrictions on study design or language. Pooled mortality estimates for countries/regions with ≥2 studies were calculated using random-effects models. RESULTS: In total 244 studies were included in the meta-analysis. 123 studies (1,382,810 patients, 13 countries/regions) reported in-hospital mortality which ranged from 1.4 % in Japan [95 %CI 1.2-1.7], Singapore [95 %CI 1.0-1.6], China [95 %CI 0.8-2.3] and Hong Kong SAR [95 %CI 0.8-2.6] to 5.5 % [95 %CI 4.1-7.2] in New Zealand. 92 studies (628,450 patients, 13 countries/regions) reported 30-day mortality which ranged from 1.2 % in Japan [95 %CI 0.9-1.5] and Thailand [95 %CI 0.7-2.0] to 7.4 % [95 %CI 7.0-7.8] in Australia. 142 studies (1,139,752 patients, 14 countries/regions) reported 1-year mortality which ranged from 10.8 % [95 %CI 9.6-12.1] in Singapore to 23.3 % [95 %CI 22.3-24.5] in Australia and 23.8 % in New Zealand. CONCLUSION: There is substantial variation in mortality across the Asia Pacific region. Short-term mortality rates in Asian countries, notably Japan and Singapore, are up to four-fold lower than for Australia and New Zealand. This difference, although less marked, is sustained at 1-year with a two-fold lower mortality rate in Asia. This meta-analysis is the first to delineate these differences, further studies are required to understand the reasons for this variation.

RESUMEN

OBJECTIVE: Although typically high, the need for information varies between cancer patients. Few studies, however, have examined the factors that predict patient information needs. This study investigated the influence of different styles of adjustment to cancer on information needs. It was proposed that adjustment styles can be defined in terms of goal pursuit and that adjustment influences information needs as these also arise from goal pursuit. METHOD: Seventy-three lung cancer patients were recruited at their first appointment with their radiation oncologist. Participants completed the Patient Information Needs Questionnaire measuring Disease Orientated (DO) information and Action Orientated (AO) information, the Mini-Mental Adjustment to Cancer Scale, and a purpose-built measure of cancer-related personal goals. RESULTS: High levels of the adjustment styles, Fighting Spirit and Anxious Preoccupation, were related to a high need for DO information (p=0.042 and 0.023, respectively). Conversely, high levels of the adjustment style Cognitive Avoidance was related to a low need for DO information (p=0.041). High levels of Anxious Preoccupation were also positively related to a high need for AO information (p=0.018). Support for the proposed theoretical model was also found: information goals predicted information needs and mediated the relationship between Fighting Spirit and DO information need. CONCLUSIONS: These findings suggest that information needs vary as a function of adjustment to cancer. Consequently information provision to cancer patients could be more appropriately tailored by attending to how a patient is adjusting to their diagnosis of cancer.

RESUMEN

The marine environment is being increasingly modified by the construction of artificial structures, the impacts of which may be mitigated through eco-engineering. To date, eco-engineering has predominantly aimed to increase biodiversity, but enhancing other ecological functions is arguably of equal importance for artificial structures. Here, we manipulated complexity through habitat structure (flat, and 2.5 cm, 5 cm deep vertical and 5 cm deep horizontal crevices) and seeding with the native oyster (Saccostrea glomerata, unseeded and seeded) on concrete tiles (0.25 m × 0.25 m) affixed to seawalls to investigate whether complexity (both orientation and depth of crevices) influences particle removal rates by suspension feeders and colonisation by different functional groups, and whether there are any ecological trade-offs between these functions. After 12 months, complex seeded tiles generally supported a greater abundance of suspension feeding taxa and had higher particle removal rates than flat tiles or unseeded tiles. The richness and diversity of taxa also increased with complexity. The effect of seeding was, however, generally weaker on tiles with complex habitat structure. However, the orientation of habitat complexity and the depth of the crevices did not influence particle removal rates or colonising taxa. Colonisation by non-native taxa was low compared to total taxa richness. We did not detect negative ecological trade-offs between increased particle removal rates and diversity and abundance of key functional groups. Our results suggest that the addition of complexity to marine artificial structures could potentially be used to enhance both biodiversity and particle removal rates. Consequently, complexity should be incorporated into future eco-engineering projects to provide a range of ecological functions in urbanised estuaries.

RESUMEN

We describe a case of invasive fungal infection caused by Volvariella volvacea following double umbilical cord blood transplantation (UCBT). Although infections caused by several mushroom species have been documented, we believe this to be the first published report of invasive infection with Volvariella volvacea, an edible mushroom belonging to Agaricales.

RESUMEN

Both normal human serum and supernatant from explanted malignant tumors contained a heat-stable low-molecular-weight factor that inhibited monocyte activation in vitro. In contrast, serum from individuals with solid tumors enhanced monocyte activation. It is suggested that the systemic activation of monocytes that occurs in malignant disease may be an appropriate host response but that successful tumors may continue to grow because they subvert the normal physiological signal for inhibition of macrophage activation.

RESUMEN

We examined the potential contribution of ventromedial (VM) tissue sparing to respiratory recovery following chronic (1 mo) unilateral C2 spinal cord injury (SCI) in rats. Preserved white matter ipsilateral to the injury was quantitatively expressed relative to contralateral white matter. The ipsilateral-to-contralateral white matter ratio was 0 after complete C2 hemisection (C2HS) and 0.23+/-0.04 with minimal VM sparing. Inspiratory (breath min(-1)) and phrenic frequency (burst min(-1)), measured by plethysmography (conscious rats) and phrenic neurograms (anesthetized rats) respectively, were both lower with minimal VM sparing (p<0.05 vs. C2HS). Tidal volume also was greater in minimal VM sparing rats during a hypercapnic challenge (p<0.05 vs. C2HS). In other C2 hemilesioned rats with more extensive VM matter sparing (ipsilateral-to-contralateral white matter ratio=0.55+/-0.05), respiratory deficits were indicated at 1 mo post-injury by reduced ventilation during hypercapnic challenge (p<0.05 vs. uninjured). Anterograde (ventral respiratory column-to-spinal cord) neuroanatomical tracing studies showed that descending respiratory projections from the brainstem are present in VM tissue. We conclude that even relatively minimal sparing of VM tissue after C2 hemilesion can alter respiratory outcomes. In addition, respiratory deficits can emerge in the adult rat after high cervical SCI even when relatively extensive VM sparing occurs.

RESUMEN

Marine harbours are the focus of a diverse range of activities and subject to multiple anthropogenically induced pressures. Support for environmental management options aimed at improving degraded harbours depends on understanding the factors which influence people's perceptions of harbour environments. We used an online survey, across 12 harbours, to assess sources of variation people's perceptions of harbour health and ecological engineering. We tested the hypotheses: 1) people living near impacted harbours would consider their environment to be more unhealthy and degraded, be more concerned about the environment and supportive of and willing to pay for ecological engineering relative to those living by less impacted harbours, and 2) people with greater connectedness to the harbour would be more concerned about and have greater perceived knowledge of the environment, and be more supportive of, knowledgeable about and willing to pay for ecological engineering, than those with less connectedness. Across twelve locations, the levels of degradation and modification by artificial structures were lower and the concern and knowledge about the environment and ecological engineering were greater in the six Australasian and American than the six European and Asian harbours surveyed. We found that people's perception of harbours as healthy or degraded, but not their concern for the environment, reflected the degree to which harbours were impacted. There was a positive relationship between the percentage of shoreline modified and the extent of support for and people's willingness to pay indirect costs for ecological engineering. At the individual level, measures of connectedness to the harbour environment were good predictors of concern for and perceived knowledge about the environment but not support for and perceived knowledge about ecological engineering. To make informed decisions, it is important that people are empowered with sufficient knowledge of the environmental issues facing their harbour and ecological engineering options.

RESUMEN

BACKGROUND: A graft-versus-lymphoma effect against diffuse large B-cell lymphoma (DLBCL) is inferred by sustained relapse-free survival after allogeneic stem-cell transplantation; however, there are limited data on a direct graft-versus-lymphoma effect against DLBCL following immunotherapeutic intervention by either withdrawal of immunosuppression or donor lymphocyte infusion (DLI). MATERIALS AND METHODS: An analysis was carried out to determine whether a direct graft-versus-lymphoma effect exists against DLBCL. The analysis was restricted to patients with DLBCL, who were either not in complete remission at day +100 after allogeneic stem-cell transplantation or subsequently relapsed beyond this time point. RESULTS: Fifteen patients were identified as either not in complete remission (n = 13) at their day +100 evaluation or subsequently relapsed (n = 2) and were assessed for subsequent responses after withdrawal of immunosuppression or DLI. Eleven patients were treated with either withdrawal of immunosuppression (n = 10) or a DLI (n = 1) alone; four patients received chemotherapy with DLI to reduce tumor bulk. Nine (60%) patients subsequently responded (complete = 8, partial = 1). Six responses occurred after withdrawal of immunosuppression alone. Six patients are alive (range 42-83+ months) in complete remission without further treatment. CONCLUSION: The demonstration of sustained complete remission following immunotherapeutic intervention provides direct evidence of a graft-versus-lymphoma effect against DLBCL.

RESUMEN

For adults with high-risk or recurrent ALL who lack a suitable sibling donor, the decision between autologous (Auto) and unrelated donor (URD) hematopoietic stem cell transplantation (HSCT) is difficult due to variable risks of relapse and treatment-related mortality (TRM). We analysed data from two transplant registries to determine outcomes between Auto and URD HSCT for 260 adult ALL patients in first (CR1) or second (CR2) CR. All patients received a myeloablative conditioning regimen. The median follow-up was 77 (range 12-170) months. TRM at 1 year post transplant was significantly higher with URD HSCT; however, there were minimal differences in TRM according to disease status. Relapse was higher with Auto HSCT and was increased in patients transplanted in CR2. Five-year leukemia-free (37 vs 39%) and overall survival (OS) rates (38 vs 39%) were similar for Auto HSCT vs URD HSCT in CR1. There were trends favoring URD HSCT in CR2. The long-term follow-up in this analysis demonstrated that either Auto or URD HSCT could result in long-term leukaemia-free survival and OS for adult ALL patients. The optimal time (CR1 vs CR2) and technique to perform HSCT remains an important clinical question for adult ALL patients.

RESUMEN

CD307 is a differentiation antigen expressed in B-lineage cells. One soluble and two membrane-bound forms have been predicted and an enzyme-linked immunosorbent assay (ELISA) for soluble CD307 established. Our goal was to determine if CD307 is expressed on the surface of cells from patients with multiple myeloma (MM), chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL) and other B-cell malignancies and if soluble CD307 levels are elevated in the blood of patients with these B-cell malignancies. Cells and blood were collected from patients. Expression of CD307 was measured by flow cytometry and blood levels of soluble CD307 by ELISA. High soluble CD307 levels were detected in 21/43 (49%) of patients with MM, 36/46 (78%) with CLL and 9/24 (38%) with MCL. Soluble CD307 levels correlated with plasma cell percentages in bone marrow aspirates in MM and total white blood cells in CLL. CD307 on the cell membrane was detected by flow cytometry in 8/8 MM, 23/29 CLL and 4/5 MCL samples. Because CD307 is present on malignant cells from patients with MM, CLL and MCL, CD307 may be a useful therapeutic target for the treatment of these diseases.
