RESUMO

A multidisciplinary approach to the management of tongue cancer is vital for achieving optimal patient outcomes. Nursing and allied health professionals play essential roles within the team. We developed symposia comprising a series of online lectures offering a detailed perspective on the role each discipline and consumer perspective has in the management of patients with tongue cancer. The topics, including epidemiology and prevention, diagnosis, treatment planning, surgery, adjuvant care, and the management of recurrent or metastatic disease, were thoroughly examined. The symposia highlighted the significance of fostering collaboration and continuous learning through a multidisciplinary approach. This initiative should be relevant to healthcare professionals, researchers, and policymakers striving to enhance patient outcomes in tongue cancer care through innovative collaboration.

RESUMO

Existing medical treatments for endometriosis-related pain are often ineffective, underscoring the need for new therapeutic strategies. In this study, we applied a computational drug repurposing pipeline to stratified and unstratified disease signatures based on endometrial gene expression data to identify potential therapeutics from existing drugs, based on expression reversal. Of 3,131 unique genes differentially expressed by at least one of six endometriosis signatures, only 308 (9.8%) were in common; however, 221 out of 299 drugs identified, (73.9%) were shared. We selected fenoprofen, an uncommonly prescribed NSAID that was the top therapeutic candidate for further investigation. When testing fenoprofen in an established rat model of endometriosis, fenoprofen successfully alleviated endometriosis-associated vaginal hyperalgesia, a surrogate marker for endometriosis-related pain. These findings validate fenoprofen as a therapeutic that could be utilized more frequently for endometriosis and suggest the utility of the aforementioned computational drug repurposing approach for endometriosis.

RESUMO

Background: Osteoporotic fractures occur in almost half of patients with a spinal cord injury (SCI) and are associated with significant morbidity and excess mortality. Paralyzed Veterans Administration (PVA) guidelines suggest that adequate calcium and vitamin D intake is important for skeletal health, however, the association of these supplements with osteoporotic fracture risk is unclear. Objectives: To determine the association of filled prescriptions for calcium and vitamin D with fracture risk in Veterans with an SCI. Methods: The 5897 persons with a traumatic SCI of at least 2 years' duration (96% male; 4% female) included in the VSSC SCI/D Registry in FY2014 were followed from FY2014 to FY2020 for incident upper and lower extremity fractures. Filled daily prescriptions for calcium or vitamin D supplements for ≥6 months with an adherence ≥80% were examined. Results: Filled prescriptions for calcium (hazard ratio [HR] 0.65; 95% CI, 0.54-0.78) and vitamin D (HR 0.33; 95% CI, 0.29-0.38) supplements were associated with a significantly decreased risk for incident fractures. Conclusion: Calcium and vitamin D supplements are associated with decreased risk of fracture, supporting PVA guidelines that calcium and vitamin D intake are important for skeletal health in persons with an SCI.

RESUMO

Background: Opioid switching is common, however, conversion tables have limitations. Guidelines suggest postswitch dose reduction, yet, observations show opioid doses may increase postswitch. Objectives: To document the opioid conversion factor postswitch in cancer, and whether pain and adverse effect outcomes differ between switched opioid groups. Design/Setting: This multicenter prospective longitudinal study included people with advanced cancer in Australia. Clinical data (demographics, opioids) and validated instruments (pain, adverse effects) were collected twice, seven days apart. Results: Opioid switch resulted in dose increase (median oral morphine equivalent daily dose 90 mg [interquartile range {IQR} 45-184] to 150 mg [IQR 79-270]), reduced average pain (5.1 [standard deviation {SD} 1.7] to 3.8 [SD 1.6]), and reduced adverse effects. Hydromorphone dose increased 2.5 times (IQR 1.0-3.6) above the original conversion factor used. Conclusions: Opioid switching resulted in overall dose increase, particularly when switching to hydromorphone. Higher preswitch dosing may require higher dose conversion ratios. Dose reduction postswitch risks undertreatment and may not be always appropriate.

RESUMO

BACKGROUND: Nearly 50% of all persons with a spinal cord injury/disorder (SCI/D) will sustain an osteoporotic fracture sometime in their life, with lower extremity fractures being the most common. There are a number of complications that can occur post fracture, including fracture malunion. To date, there have been no dedicated investigations of malunions among persons with SCI/D. OBJECTIVES: The primary objective of this study was to identify risk factors associated with fracture malunion among fracture-related (type of fracture, fracture location, initial fracture treatment) and SCI/D-related factors. Secondary objectives were to describe treatment of fracture malunions and complications following these malunions. METHODS: Veterans with SCI/D with an incident lower extremity fracture and subsequent malunion from Fiscal Year (FY) 2005-2015 were selected from the Veteran Health Administration (VHA) databases using International Classification of Diseases, 9th edition (ICD-9) codes for lower extremity fractures and malunion. These fracture malunion cases underwent electronic health record (EHR) review to abstract information on potential risk factors, treatments and complications for malunion. Twenty-nine cases were identified with a fracture malunion with 28 of them successfully matched with Veterans with a lower extremity fracture during FY2005-FY2014 without a malunion (matched 1:4) based on having an outpatient utilization date of care within 30 days of the fracture case. There was trend towards more nonsurgical treatment in the malunion group (n = 27, 96.43%) compared to the control group (n = 101, 90.18%) (P = 0.05), though fracture treatment proved not to be not associated with developing a malunion in univariate logistic regression analyses (OR = 0.30; 95% CI: 0.08-1.09). In multivariate analyses, Veterans with tetraplegia were significantly less likely (approximately 3-fold) to have a fracture malunion (OR = 0.38; 95% CI: 0.14-0.93) compared to those with paraplegia. Fracture malunion was significantly less likely to occur for fractures of the ankle (OR = 0.02; 95% CI: 0-0.13) or the hip (OR = 0.15; 95% CI: 0.03-0.56) compared to femur fractures. Fracture malunions were rarely treated. The most common complications following malunions were pressure injuries (56.3%) followed by osteomyelitis (25.0%). CONCLUSIONS: Persons with tetraplegia as well as fractures of the ankle and hip (compared to the femur) were less likely to develop a fracture malunion. Attention to prevention of avoidable pressure injuries following a fracture malunion is important.

RESUMO

Aim: Associations between gene variants and opioid net effect are unclear. We conducted an exploratory pharmacogenetic analysis of 35 gene variants and opioid response in advanced cancer. Patients & methods: This multi-center prospective cohort study included clinical data, questionnaires (pain and adverse effects) and DNA (blood). Negative binomial regression and logistic regression were used. Results: Within 54 participants, eight statistically significant associations (p = 0.002-0.038) were observed between gene variants and opioid dose, pain scores or adverse effects, the majority being within the neuroimmune TLR4 pathway (IL1B [rs1143634], IL2 [rs2069762], IL6 [rs1800795], BDNF [rs6265]) and ARRB2 pathway (ARRB2 [rs3786047], DRD2 [rs6275]). Conclusion: Neuroimmune pathway genes may contribute to differences in opioid response in cancer and may be included in future similar studies.

RESUMO

OPINION STATEMENT: In considering the impact of medically hastened death (MHD) on cancer care, a wide range of variables needs to be considered including demographic factors, diagnoses, local cultural factors, and the legislative frameworks in place. Here, we present a synthesis of recently available published literature and empirical data collected following legislative change to enable MHD in Victoria, Australia to explore in detail the potential impact of MHD on cancer care with a focus on patients/families and professional groups. Our findings reveal that for patients and families, both physical and existential distress frequently underlie MHD requests, with the latter less readily recognised by health professionals. The responses of those around the patient making the request may have a very significant impact on relationships within families and upon the nature of the subsequent bereavement. For palliative care, while differing views may remain, it appears that there has been some accommodation of MHD into or alongside practice over time. The recognition of a shared commitment to relief of suffering of palliative care and MHD appears a helpful means of establishing how these practices may co-exist. In cancer practice more broadly, as individual professionals reflect upon their own roles, new relationships and pathways of patient movement (or referral) must be established in response to patients' requests. Our findings also highlight many unanswered questions in understanding the impact of MHD, including that upon those dying who choose not to access MHD, First Nations peoples, the participating health professionals' longer term, and the relief of suffering itself. A systematic approach to the evaluation of MHD legislation must be adopted in order to understand its full impact. Only then could it be determined if the aspirations for such legislative change were being met.

RESUMO

Microscopes are essential for the biomechanical and hydrodynamical investigation of small aquatic organisms. We report a do-it-yourself microscope (GLUBscope) that enables the visualization of organisms from two orthogonal imaging planes - top and side views. Compared to conventional imaging systems, this approach provides a comprehensive visualization strategy of organisms, which could have complex shapes and morphologies. The microscope was constructed by combining custom 3D-printed parts and off-the-shelf components. The system is designed for modularity and reconfigurability. Open-source design files and build instructions are provided in this report. Additionally, proof-of-use experiments (particularly with Hydra) and other organisms that combine the GLUBscope with an analysis pipeline were demonstrated to highlight the system's utility. Beyond the applications demonstrated, the system can be used or modified for various imaging applications.

RESUMO

Opioid switching is a common practice of substituting one opioid for another to improve analgesia or adverse effects; however, it has limited evidence. This study aimed to examine the effectiveness of opioid switching in advanced cancer. This multi-center prospective cohort study recruited patients assessed to switch opioids (opioid switch group) or to continue ongoing opioid treatment (control group). Clinical data (demographics, opioids) and validated instruments (pain and adverse effects) were collected over two timepoints seven days apart. Descriptive analyses were utilized. Non-parametric tests were used to determine differences. Fifty-four participants were recruited (23 control group, 31 switch group). At the follow-up, opioid switching reduced pain (worst, average, and now) (p < 0.05), uncontrolled breakthrough pain (3-fold reduction, p = 0.008), and psychological distress (48% to 16%, p < 0.005). The switch group had a ≥25% reduction in the reported frequency of seven moderate-to-severe adverse effects (score ≥ 4), compared to a reduction in only one adverse effect in the control group. The control group experienced no significant pain differences at the follow-up. Opioid switching is effective at reducing pain, adverse effects, and psychological distress in a population with advanced cancer pain, to levels of satisfactory symptom control in most patients within 1 week.

RESUMO

This study explores and describes the state-wide needs of the first 1000 calls to the newly established Victorian Palliative Care Advice Service (PCAS). A retrospective analysis investigated calls from the Victorian general public (n = 618 calls) and healthcare professionals (n = 382 calls) to PCAS between 26 May 2020 and 24 October 2022. Caller demographics, disease type, reason for call, and perceived utility of service were described. Most calls were from members of the public (62%) and related to malignant conditions (41%). Regional/rural clients comprised 45% of all calls to the service, of which half (50%) were health professionals seeking advice on symptom management and medication. One-third (29.3%) of all calls from health professionals were escalated to a palliative care medical consultant. PCAS prevented calls to emergency services in 10% of cases, and 82% of callers reported their issue was 'very much' or 'completely' addressed by PCAS. PCAS was shown to be frequently used by the public and healthcare professionals supporting patients with advanced, life-limiting illnesses. The service provided a solution without requiring complex technology, delivering a rapid connection for consumers with specialist palliative care expertise that might otherwise be unavailable, particularly in regional areas.

RESUMO

Objective High-quality end-of-life care involves addressing patients' physical, psychosocial, cultural and spiritual needs. Although the measurement of the quality of care associated with dying and death is an important component of health care, there is a lack of evidence-based, systematic processes to examine the quality of dying and death of patients in hospital settings. Our purpose was to develop a systematic appraisal framework (QualDeath) for reviewing the quality of dying and death for patients with advanced cancer. The objectives were to: (1) explore the evidence regarding existing tools and processes related to appraisal of end-of-life care; (2) examine existing practices related to appraisal of quality of dying and death in hospital settings; and (3) develop QualDeath with consideration of potential acceptability and feasibility factors. Methods A co-design multiple methods approach was used. For objective 1, a rapid literature review was undertaken; for objective 2 we carried out semi-structured interviews and focus groups with key stakeholders in four major teaching hospitals; and for objective 3 we interviewed key stakeholders and held workshops with the project team to reach consensus. Results We developed QualDeath, a framework to assist hospital administrators and clinicians to systematically and retrospectively review the quality of dying and death for patients expected to die from advanced cancer. It offers four levels of potential implementation for hospitals to select from and incorporates medical record review, multidisciplinary meetings, quality of end-of-life care surveys and bereavement interviews with family carers. Conclusions The QualDeath framework provides hospitals with recommendations to formalise processes to evaluate end-of-life care. Although QualDeath was underpinned by several research methods, further research is needed to rigorously explore its impact and test its feasibility.

RESUMO

BACKGROUND: Despite global support, there remain gaps in the integration of early palliative care into cancer care. The methods of implementation whereby evidence of benefits of palliative care is translated into practice deserve attention. AIM: To identify implementation frameworks utilised in integrated palliative care in hospital-based oncology services and to describe the associated enablers and barriers to service integration. DESIGN: Systematic review with a narrative synthesis including qualitative, mixed methods, pre-post and quasi experimental designs following the guidance by the Centre for Reviews and Dissemination (PROSPERO registration CRD42021252092). DATA SOURCES: Six databases searched in 2021: EMBASE, EMCARE, APA PsycINFO, CINAHL, Cochrane Library and Ovid MEDLINE searched in 2023. Included were qualitative or quantitative studies, in English language, involving adults >18 years, and implementing hospital-based palliative care into cancer care. Critical appraisal tools were used to assess the quality and rigour. RESULTS: Seven of the 16 studies explicitly cited the use of frameworks including those based on RE-AIM, Medical Research Council evaluation of complex interventions and WHO constructs of health service evaluation. Enablers included an existing supportive culture, clear introduction to the programme across services, adequate funding, human resources and identification of advocates. Barriers included a lack of communication with the patients, caregivers, physicians and palliative care team about programme goals, stigma around the term 'palliative', a lack of robust training, or awareness of guidelines and undefined staff roles. CONCLUSIONS: Implementation science frameworks provide a method to underpin programme development and evaluation as palliative care is integrated within the oncology setting.

RESUMO

CONTEXT: Insomnia is an under-recognized and undertreated symptom in palliative care and advanced cancer cohorts. Insomnia in an advanced colorectal cancer cohort is yet to be investigated despite colorectal cancer being the third commonest cancer worldwide and one with a high symptom burden. OBJECTIVES: To examine the prevalence of insomnia and its associations in a large advanced colorectal cancer cohort. METHODS: A consecutive cohort study of 18,302 patients with colorectal cancer seen by palliative care services across various settings (inpatient, outpatient, and ambulatory) was conducted from an Australia-wide database (2013-2019). The Symptom Assessment Score (SAS) was used to assess the severity of insomnia. Clinically significant insomnia was defined as SAS score ≥3/10, and used to compare associations with other symptoms and functional scores from validated questionnaires. RESULTS: The prevalence of any insomnia was 50.5%, and clinically significant insomnia 35.6%, particularly affecting people who were younger (<45-years-old), more mobile (AKPS score ≥70), or physically capable (RUG-ADL score ≤5). Outpatients and patients living at home had higher prevalence of insomnia. Nausea, anorexia and psychological distress were the commonest concurrent symptoms in patients with clinically significant insomnia. CONCLUSIONS: To our knowledge, this study was the first to investigate the prevalence and associations of insomnia in an advanced colorectal cancer cohort. Our findings demonstrate several groups at greater risk of suffering from insomnia (younger, greater physical capacity, living at home, and those with greater psychological distress). This may guide earlier recognition and management of insomnia to improve overall quality of life in this population.

RESUMO

Drug repurposing requires distinguishing established drug class targets from novel molecule-specific mechanisms and rapidly derisking their therapeutic potential in a time-critical manner, particularly in a pandemic scenario. In response to the challenge to rapidly identify treatment options for COVID-19, several studies reported that statins, as a drug class, reduce mortality in these patients. However, it is unknown if different statins exhibit consistent function or may have varying therapeutic benefit. A Bayesian network tool was used to predict drugs that shift the host transcriptomic response to SARS-CoV-2 infection towards a healthy state. Drugs were predicted using 14 RNA-sequencing datasets from 72 autopsy tissues and 465 COVID-19 patient samples or from cultured human cells and organoids infected with SARS-CoV-2. Top drug predictions included statins, which were then assessed using electronic medical records containing over 4,000 COVID-19 patients on statins to determine mortality risk in patients prescribed specific statins versus untreated matched controls. The same drugs were tested in Vero E6 cells infected with SARS-CoV-2 and human endothelial cells infected with a related OC43 coronavirus. Simvastatin was among the most highly predicted compounds (14/14 datasets) and five other statins, including atorvastatin, were predicted to be active in > 50% of analyses. Analysis of the clinical database revealed that reduced mortality risk was only observed in COVID-19 patients prescribed a subset of statins, including simvastatin and atorvastatin. In vitro testing of SARS-CoV-2 infected cells revealed simvastatin to be a potent direct inhibitor whereas most other statins were less effective. Simvastatin also inhibited OC43 infection and reduced cytokine production in endothelial cells. Statins may differ in their ability to sustain the lives of COVID-19 patients despite having a shared drug target and lipid-modifying mechanism of action. These findings highlight the value of target-agnostic drug prediction coupled with patient databases to identify and clinically evaluate non-obvious mechanisms and derisk and accelerate drug repurposing opportunities.

RESUMO

Opioids are the backbone of cancer pain management. Minimal evidence exists examining the relationship between cancer type and opioid dose. Similarly, the use of adjuvant analgesics and its impact within an inpatient cancer setting is understudied. This study examined the influence of cancer type upon opioid dose, measured by oral morphine equivalent daily dose (oMEDD). The effect of adjuvant analgesics on patient oMEDD was also examined. This retrospective cross-sectional study examined records of 520 patients admitted to Royal Melbourne Hospital or Peter MacCallum Cancer Centre between 2016 and 2018 with advanced cancer. Number and dose of both opioid and adjuvant analgesics were collected along with demographic and cancer data. Comparisons of median oMEDD by cancer type [analysis of variance (ANOVA), non-parametric t-tests] and adjuvant analgesics (Kruskal-Wallis test) were performed. There were no statistically significant differences in oMEDD between the 12 cancer types (P=0.83; n=215). Patients co-prescribed pregabalin (n=102) and paracetamol (n=73) as adjuvant analgesics were on significantly higher daily oMEDD [60 mg (P=0.015), 90 mg (P<0.001), respectively]. Opioid dose did not differ significantly between cancer types. The observed use of adjuvant analgesics coincided with significantly higher oMEDD prescription which may relate to complex pain seen in this cohort of inpatients in a quarternary cancer centre. Future research should focus on pain type and aetiology, and pain scores in different cancer pain syndromes to determine the net effect of opioids and adjuvants in cancer pain prescribing.
