Leadership, Leading, and Influencing Change in Cancer Education: Development and Assessment of a Pilot Leadership Workshop in Cancer Education for Interdisciplinary Healthcare Staff.

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.

Making seawalls multifunctional: The positive effects of seeded bivalves and habitat structure on species diversity and filtration rates.

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.

Exploring the relationship between chronic pain and cortisol levels in subjects with osteoarthritis: results from a systematic review of the literature.

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.

Urban blue: A global analysis of the factors shaping people's perceptions of the marine environment and ecological engineering in harbours.

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.

Building blue infrastructure: Assessing the key environmental issues and priority areas for ecological engineering initiatives in Australia's metropolitan embayments.

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.

The patient-dentist relationship and the future of dentistry.

The patient-dentist relationship is a delicate partnership that forms the core of dentistry. The attack on this partnership by the General Dental Council has led to gross miscarriages of justice and the emergence of defensive dentistry. This essay considers the role of a governing body, the misconduct of the GDC and the response of the profession to the injustices perpetrated. The system of NHS general dental practice is considered in terms of quality and humanity and found to be failing in quality and lacking in humanity. The paper concludes that the General Dental Council must go and that NHS general dental practice needs to be terminated. The GDC is apparently not accountable to anyone but the practice of dentistry is accountable to the dentists. The profession will need to be courageous and take action to bring about radical change. A new governing body consisting of young dentists and older more experienced dentists will establish a proper system of professional standards and care for patients. A new, dentist-controlled private system of subsidised general dental practice will be introduced using government financial support for dentistry. The patient-dentist partnership will thus be able to move into a new era of quality and humanity.

Comparison of multiple thawing techniques on thaw time and stability of hemostatic proteins in canine plasma products.

OBJECTIVES: To compare thawing times of fresh frozen canine plasma between a 37 °C warm water bath, running water bath and dry plasma thawer and compare haemostatic protein stability after thawing in a warm water bath or dry plasma thawer. MATERIALS AND METHODS: To measure thawing times, a 240-mL bag of frozen plasma was thawed in warm water bath, running water bath or dry plasma thawer-10 times for each method. To evaluate stability of haemostatic proteins, fresh canine donor plasma samples were split into 120-mL bags and 3-mL control aliquots before freezing. Bags were thawed by warm water bath or dry plasma thawer and aliquots equilibrated to room temperature. Concentrations of haemostatic proteins, albumin, D-dimers, prothrombin time and partial thromboplastin time were obtained. RESULTS: The running water bath had the shortest thaw time: median thaw time of 15 minutes versus 18 minutes for both the dry plasma thawer and warm water bath. Statistically significant differences in partial thromboplastin time, factor VII, factor X, von Willebrand factor, and von Willebrand factor collagen binding assay were detected among groups but were unlikely to be clinically relevant. CLINICAL SIGNIFICANCE: A traditional running water bath provided the fastest thawing time but the dry plasma thawer resulted in the most stable haemostatic proteins.

Post-autologous transplant maintenance therapies in lymphoma: current state and future directions.

Disease relapse following high-dose chemotherapy and autologous stem cell transplant (ASCT) remains the principal cause of mortality in patients with relapsed or refractory lymphomas. In an effort to prevent post-ASCT relapse, a number of studies have evaluated the role of maintenance therapy with varying success. In diffuse large B-cell lymphoma, studies evaluating maintenance rituximab (MR) following ASCT failed to demonstrate improved outcomes. In follicular lymphoma, MR was associated with an improvement in PFS; however, no overall survival (OS) benefit was noted. Emerging data evaluating MR in mantle cell lymphoma (MCL) have demonstrated improvements in PFS, although a consistent improvement in OS has yet to be demonstrated. Given the aggressive and incurable nature of MCL, it is prudent for practitioners to weigh the risks and benefits of MR in the post-ASCT setting. Similarly, post-ASCT maintenance therapy with brentuximab vedotin in Hodgkin lymphoma, has led to improved PFS and may be considered in those with a high risk of relapse. Ongoing clinical studies evaluating a multitude of novel maintenance therapies are crucial to the efforts of further defining and optimizing the role of post-transplant maintenance therapy in lymphoma.

Biochemical evaluation of storage lesion in canine packed erythrocytes.

OBJECTIVES: To describe the biochemical changes - also known as the storage lesion - that occur in canine packed red blood cells during ex vivo storage. MATERIALS AND METHODS: Ten 125-mL units of non-leuco-reduced packed red blood cells in citrate phosphate dextrose adenine were obtained from a commercial blood bank within 24 hours of donation. Samples were aseptically collected on days 1, 4, 7, 14, 28, 35 and 42 for measurement of sodium, potassium, chloride, lactate, glucose, pH and ammonia concentrations. All units were cultured on day 42. Friedman's repeated measures test with Dunn's multiple comparison test was used for non-parametric data. A repeated-measures analysis of variance with Tukey's multiple comparison test was used for parametric data. Alpha was set to 0·05. RESULTS: All analytes changed significantly during storage. The mean ammonia on day 1 (58·14 g/dL) was significantly lower (P<0·05) than those on days 28 (1266 g/dL), 35 (1668 g/dL) and 42 (1860 g/dL). A significant increase in median lactate concentration over time was also observed, with day 1 (4·385 mmol/L) being significantly less (P<0·05) than days 14 (19·82 mmol/L), 21 (22·81 mmol/L), 35 (20·31 mmol/L) and 42 (20·81 mmol/L). Median pH was significantly decreased after day 7. All bacterial cultures were negative. CLINICAL SIGNIFICANCE: Many biochemical alterations occur in stored canine packed red blood cells, although further studies are required to determine their clinical importance.

Dietary management of presumptive protein-losing enteropathy in Yorkshire terriers.

OBJECTIVES: To describe the clinical outcome of dietary management of Yorkshire terriers with protein-losing enteropathy without immunosuppressive/anti-inflammatory medications. METHODS: Records were searched for Yorkshire terriers with hypoalbuminaemia and a clinical diagnosis of protein-losing enteropathy that were managed with diet and without immunosuppressive/anti-inflammatory medications. Serum albumin changes were compared using a one-way repeated measures ANOVA. Canine chronic enteropathy clinical activity index scores were compared using a Wilcoxon signed-rank test. RESULTS: Eleven cases were identified. Clinical signs were variable including: diarrhoea, respiratory signs, vomiting, lethargy and weight loss. Diets fed included home cooked (n=5); Royal Canin Gastrointestinal Low Fat (n=4); Hill's Prescription Diet i/d Low Fat (n=1); or Purina HA Hypoallergenic (n=1). Clinical signs resolved completely in eight dogs, partially resolved in two dogs and failed to respond in one dog. In dogs that responded, albumin significantly improved from baseline (mean 14·9 g/L, sd ±3·7), at 2 to 4 weeks (mean 24·2 g/L, sd ±5·5, P=0·01), and at 3 to 4 months (mean 27·0 g/dL, sd ±5·9, P=0·01). CLINICAL SIGNIFICANCE: These results indicate that dietary management of protein-losing enteropathy is a potential management strategy in Yorkshire terriers. Randomised clinical trials in Yorkshire terriers with protein-losing enteropathy are necessary to compare success rate, survival and quality of life with dietary management versus combined dietary and immunosuppressive/anti-inflammatory therapy.

Long-term functional outcomes and quality of life in adult survivors of childhood extremity sarcomas: a report from the St. Jude Lifetime Cohort Study.

PURPOSE: This study compared measured physical performance, health-related quality of life (HRQOL), and social role attainment between extremity sarcoma survivors and controls, and evaluated associations between disease and treatment exposures, health conditions, and performance measures. METHODS: Survivors of extremity sarcoma from the St. Jude Lifetime cohort and controls frequency matched by age-, sex-, and race completed physical performance testing and questionnaires. Survivors with Z-scores on outcome measures ≤ -2.0 SD (compared to controls) were categorized with severe impairment/limitation. RESULTS: Among 206 survivors (52.4 % male median age 36 years (range 19-65)), 37 % had low relative lean mass, 9.7 % had an ejection fraction <50 %, 51.5 % had diffusion capacity for carbon monoxide <75 %, 27.7 % had sensory and 25.2 % motor neuropathy, and 78.2 % had musculoskeletal complications. Severe impairments/limitations were present among ≥25 % of survivors on fitness, balance, and physical HRQOL measures, and among ≥15 % on strength and activity of daily living measures. Lower extremity tumor location (OR 8.23, 95 % CI 2.54-26.67, P value 0.0004) and amputation (OR 8.07, 95 % CI 3.06-21.27, P value <0.0001) were associated with poor fitness. Poor fitness was associated with increased odds of scoring <40 on the SF-36 physical component summary (OR 4.83, 95 % CI 1.95-11.99, P value 0.001) and role-physical subscale (OR 3.34, 95 % CI 1.33-8.43, P value 0.01). Survivors and controls had similar rates of marriage, independent living, employment, and college attendance. CONCLUSIONS: Extremity sarcoma survivors experience high rates of physical impairment and report lower than expected physical HRQOL. However, they are as likely as peers to be married, live independently, be employed, and attend college. IMPLICATIONS FOR CANCER SURVIVORS: Follow-up for extremity sarcoma survivors should include assessment of need for further orthopedic care and rehabilitation to address cardiopulmonary and musculoskeletal health.

Prevalence of pain in the departments of surgery and oncohematology of a paediatric hospital that has joined the project "Towards pain free hospital".

BACKGROUND: Among hospitalized adults and children pain is undertreated. This study wants to assess the effectiveness of pain therapy in two departments of a large children's hospital. MATERIALS AND METHODS: During a single day work three committees, administering a questionnaire to patients or parents, have evaluated the adherence to international recommendations (JCI and WHO) in the management of analgesic therapy. Patient demographics, prevalence and intensity (moderate and/or severe) of pain (during hospitalization, 24 hours before and at the time of the interview), analgesia (type, route, duration and frequency of administration) and Pain Management Index (=analgesic score-pain score) were recorded. RESULTS: 75 patients participated in the study (age: 2 months up to 24 years, mean 7.8 ± 6). During hospitalization 43 children (57%) had no pain while 32 (43%) have experienced pain. 22 children (29 %) had pain 24 hours before and 12 (16%) at the time of the interview. The average value of the PMI was -0.8±1.3 with a minimum of -3 and a maximum of +2: 60% (19) of the children had a PMI less than 0 (undertreated pain) while 40% (13) had a value=or>0. Out of 32 patients who needed an analgesic therapy 14 (44%) received an around-the-clock dosing, 8 (25%) an intermittent therapy and 10 (31%) no treatment.17 (77 %) were the single drug therapy and 5 (23%) the multimodal ones. CONCLUSIONS: The prevalence of pain in the two departments is high. The main cause is that knowledge is not still well translated into clinical practice.

Biochemical evaluation of the effects of storage on feline erythrocytes.

OBJECTIVE: To describe the biochemical changes that occur during storage of feline packed red blood cells. METHODS: Feline packed red blood cells were obtained from the manufacturer via overnight delivery immediately following collection. Bag spikes were placed using aseptic technique and samples were drawn on days 1, 4, 7, 14, 21, 28 and 35. Sodium, potassium, chloride, glucose, lactate, pH and ammonia were measured at each time point. Aerobic and anaerobic bacterial cultures were submitted following collection on day 35. RESULTS: There were statistically significant increases in the median concentrations of lactate and ammonia within the first 2 weeks of storage to a concentration of 12·38 mmol/L and 447·96 µmol/L, respectively. Glucose concentrations decreased significantly by day 28 to a mean of 1·86 mmol/L. Median sodium and chloride concentrations increased throughout the course of storage to a concentration of 158·20 and 131·00 mmol/L, respectively. Mean potassium concentrations decreased to a concentration of 2·40 mmol/L. CLINICAL SIGNIFICANCE: These results show that biochemical derangements within feline packed red blood cells are progressive, with some alterations, such as lactate and ammonia, occurring early within the storage periods, while others, including glucose and electrolytes, are slower to develop. Additional prospective research evaluating the clinical effects of these biochemical alterations is required.

'The Dentist's Hands': An analysis of the portrait by Fiona Graham-Mackay.

One hundred and fifty years ago, a dentist practising in Tavistock signed off a letter to the editor of The British Journal of Dental Science, 'Suaviter et Fortiter'. This paper discusses the commissioning from the eminent portrait painter Fiona Graham-Mackay of a painting of a dentist's hands. In the course of the sittings, the artist commented that as the mirror and probe were picked up, the hands took on an authority they did not have before. If the portrait is successful, it is so in demonstrating the gentle but firm authority, suaviter et fortiter, of the profession.
