RESUMO

OBJECTIVES: Many oncology health professionals (HPs) report communicating with carers as complex; and receive limited carer-relevant training. We developed an online HP education program for supporting and managing carer involvement (eTRIO). We aimed to assess whether HPs' self-efficacy in carer communication, knowledge, and decision-making preferences improve following eTRIO. Satisfaction and implementation potential were assessed. METHODS: This type 1 hybrid effectiveness-implementation study used a pre-post single arm intervention design. HPs completed baseline measures, the eTRIO online module, and measures at 1- and 12-weeks post-intervention. Measures included: self-efficacy in carer communication (13-items), applied knowledge (7-items), preference for carer involvement in decisions (1-item). Fifteen of participants completed feedback interviews which underwent thematic analysis. User analytics were collected and analysed. RESULTS: Fifty-six HPs completed baseline measures, 42 completed post- and follow-up measures. At baseline mean self-efficacy score was 88. HPs showed a statistically significant increase in self-efficacy post-intervention (mean = 105.8, CI [12.99, 20.47]), maintained at 12-weeks (mean = 101.1, CI [8.00, 15.72]). There were no changes in knowledge or decision-making preferences. Program engagement and satisfaction were high, 86.7% participants rated eTRIO as very/extremely helpful. CONCLUSIONS AND PRACTICE IMPLICATIONS: eTRIO provided HPs with confidence to effectively engage with carers and manage complex situations such as family dominance. These gains are noteworthy, as conflict with families/carers contributes to HP burnout.

RESUMO

BACKGROUND: Carers often assume key roles in cancer care. However, many carers report feeling disempowered and ill-equipped to support patients. Our group published evidence-based guidelines (the Triadic Oncology [TRIO] Guidelines) to improve oncology clinician engagement with carers and the management of challenging situations involving carers. OBJECTIVE: To facilitate implementation of the TRIO Guidelines in clinical practice, we aimed to develop, iteratively refine, and conduct user testing of a suite of evidence-based and interactive web-based education modules for oncology clinicians (e-Triadic Oncology [eTRIO]), patients with cancer, and carers (eTRIO for Patients and Carers [eTRIO-pc]). These were designed to improve carer involvement, communication, and shared decision-making in the cancer management setting. METHODS: The eTRIO education modules were based on extensive research, including systematic reviews, qualitative interviews, and consultation analyses. Guided by the person-based approach, module content and design were reviewed by an expert advisory group comprising academic and clinical experts (n=13) and consumers (n=5); content and design were continuously and iteratively refined. User experience testing (including "think-aloud" interviews and administration of the System Usability Scale [SUS]) of the modules was completed by additional clinicians (n=5), patients (n=3), and carers (n=3). RESULTS: The final clinician module comprises 14 sections, requires approximately 1.5 to 2 hours to complete, and covers topics such as carer-inclusive communication and practices; supporting carer needs; and managing carer dominance, anger, and conflicting patient-carer wishes. The usability of the module was rated by 5 clinicians, with a mean SUS score of 75 (SD 5.3), which is interpreted as good. Clinicians often desired information in a concise format, divided into small "snackable" sections that could be easily recommenced if they were interrupted. The carer module features 11 sections; requires approximately 1.5 hours to complete; and includes topics such as the importance of carers, carer roles during consultations, and advocating for the patient. The patient module is an adaptation of the relevant carer module sections, comprising 7 sections and requiring 1 hour to complete. The average SUS score as rated by 6 patients and carers was 78 (SD 16.2), which is interpreted as good. Interactive activities, clinical vignette videos, and reflective learning exercises are incorporated into all modules. Patient and carer consumer advisers advocated for empathetic content and tone throughout their modules, with an easy-to-read and navigable module interface. CONCLUSIONS: The eTRIO suite of modules were rigorously developed using a person-based design methodology to meet the unique information needs and learning requirements of clinicians, patients, and carers, with the goal of improving effective and supportive carer involvement in cancer consultations and cancer care.

RESUMO

BACKGROUND: Many colorectal cancer (CRC) survivors experience ongoing sequelae from their cancer treatment. Limited evidence exists regarding how CRC survivors and general practitioners (GPs) manage these sequelae in the community. This study aimed to explore the experiences and perspectives of CRC survivors and GPs on current approaches to monitoring and managing sequelae of CRC treatment. METHODS: We conducted a mixed-methods study using cross-sectional national surveys and qualitative interviews with CRC survivors and GPs to explore: (1) treatment sequelae experienced by CRC survivors, (2) how these were monitored and managed by general practitioners, and (3) suggestions to improve ongoing management of the treatment sequelae. Survey responses were reported descriptively. Qualitative data were thematically analysed using an interpretive descriptive approach. RESULTS: Seventy participants completed surveys: 51 CRC survivors and 19 GPs, and four interviews were conducted with GPs. CRC survivors experienced a range of treatment sequelae, but often did not discuss these with their GPs (experienced vs discussed: 86% vs 47% for fatigue/lack of energy, 78% vs 27% for psychological/emotional concern, 63% vs 22% for impaired sleep, 69% vs 29% for weight loss/gain, 59% vs 16% for sexual and intimacy concerns). GPs reported inadequate information transfer from cancer services and workload as major barriers to optimal care. CONCLUSIONS: System-level changes that facilitate adequate information transfer from cancer services to GPs upon CRC treatment completion, as well as addressing time constraint issues essential for comprehensive monitoring and management of CRC treatment sequelae, could enhance the care of CRC survivors in the community setting.

RESUMO

BACKGROUND: Having a cancer diagnosis during early adulthood can be a significant challenge for an individual. Nurses' supportive communication plays a vital role during the diagnosis and treatment period to lessen psychological distress and promote coping. OBJECTIVE: This exploratory study aimed to examine (1) the experiences of emerging adults with cancer (EAs) aged between 18 and 25 years in communicating with nurses during diagnosis and treatment and (2) nurses' experiences of providing supportive communication with this patient group. METHODS: Semistructured interviews were conducted with EAs and nurses with experience caring for this patient group. Thematic analysis was conducted, guided by interpretive hermeneutic perspectives. RESULTS: Eight EA participants and 7 nurse participants participated in interviews. Five themes emerged: (1) having casual conversations with nurses helped EAs cope during cancer treatment and (2) helped EAs fulfill the need for social connectedness, (3) nurses as a different form of peer-like support, (4) nurses used themselves as a therapeutic tool to foster trust and emotional safety of EAs, and (5) nurses needed to maintain professional boundaries while being compassionate. CONCLUSIONS: This study highlighted a rather underdocumented aspect of supportive communication: meeting psychosocial needs through casual, day-to-day conversations. IMPLICATIONS FOR PRACTICE: Having casual conversations with nurses appeared to help EAs' psychological coping during cancer treatment. These casual conversations, which on the surface seemed clinically insignificant, fulfilled their psychosocial needs. Considering the valuable interpersonal engagement that led to emotional benefits for EAs, communication training for cancer nurses needs to build their capacity to maintain both relational and emotional boundaries.

RESUMO

Actin mediates insulin secretion in pancreatic ß-cells through remodeling. Hampered by limited resolution, previous studies have offered an ambiguous depiction as depolymerization and repolymerization. We report the in situ structure of actin remodeling in INS-1E ß-cells during glucose-stimulated insulin secretion at nanoscale resolution. After remodeling, the actin filament network at the cell periphery exhibits three marked differences: 12% of actin filaments reorient quasi-orthogonally to the ventral membrane; the filament network mainly remains as cell-stabilizing bundles but partially reconfigures into a less compact arrangement; actin filaments anchored to the ventral membrane reorganize from a "netlike" to a "blooming" architecture. Furthermore, the density of actin filaments and microtubules around insulin secretory granules decreases, while actin filaments and microtubules become more densely packed. The actin filament network after remodeling potentially precedes the transport and release of insulin secretory granules. These findings advance our understanding of actin remodeling and its role in glucose-stimulated insulin secretion.

RESUMO

PURPOSE: The aim of this randomised controlled trial (RCT) was to explore whether a community nursing intervention for outpatients receiving systemic therapy reduced unplanned hospital presentations and improved physical and psychosocial health outcomes over the first three cycles of treatment compared to a control group receiving standard care. METHODS: The number of and reasons for unplanned presentations were obtained for 170 intervention and 176 control group adult patients with solid tumours starting outpatient chemotherapy. Poisson regression was used to compare the number of presentations between the intervention and control groups. Patients self-completed the Hospital Anxiety and Depression Scale, the Cancer Behavior Inventory and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire core 30 (EORTC QLQ-C30) at the start of the first four cycles. Linear regression techniques were used to compare quality of life outcomes. RESULTS: The reduction in unplanned presentations in the intervention group relative to the control group was 12% (95% CI, - 25%, 37%; P = 0.48). At the start of cycle 4, there was no difference in anxiety (difference = 0.47 (95% CI, - 0.28, 1.22; P = 0.22)), depression (difference = 0.57 (95% CI, - 0.18, 1.31; P = 0.13)) or EORTC QLQ-C30 summary score (difference = 0.16 (95% CI, - 2.67, 3.00; P = 0.91)). Scores for self-efficacy as measured by the Cancer Behavior Inventory were higher in the intervention group (difference = 4.3 (95% CI, 0.7, 7.9; P = 0.02)). CONCLUSION: This RCT did not demonstrate a benefit in reducing unplanned presentations to hospital. The trial identified improved cancer-based self-efficacy in patients receiving the intervention.

RESUMO

The objective of this study was to assess the viability and acceptability of an innovative Virtual Wound Care Command Centre where patients in the community, and their treating clinicians, have access to an expert wound specialist service that comprises a digital wound application (app) for wound analysis, decision-making, remote consultation, and monitoring. Fifty-one patients with chronic (42.6%) wounds were healed, with a median time to healing of 66 (95% CI: 56-88) days. All patients reported high satisfaction with their wound care, 86.4% of patients recommended the Virtual Wound Care Command Centre with 84.1% of patients reporting the app as easy to use. The data revealed that the Virtual Wound Care Command Centre was a viable and acceptable patient-centred expert wound consultation service for chronic wound patients in the community.

RESUMO

BACKGROUND: Understanding ethical challenges experienced in relation to adverse events is necessary to inform strategies that optimise patient safety and practitioner wellbeing. METHODS: A qualitative exploration of UK veterinary practitioners' experiences of adverse events was conducted. Data were collected via 12 focus groups and 20 interviews and analysed using an inductive coding technique. RESULTS: Questions surrounding acceptable boundaries of care, decision-making autonomy, personal scope of practice, use of evidence and speaking up about patient safety concerns were identified as ethically challenging to practitioners when endeavouring to prevent adverse events. Issues of appropriate accountability, interaction and communication with animal owners and the prioritisation of emotional and technical support for themselves and others were identified as ethically challenging in the aftermath of adverse events. LIMITATIONS: The qualitative nature of this study limits the generalisability of the findings. CONCLUSIONS: Ethical challenges are experienced by veterinary practitioners in relation to both preventing and responding in the aftermath of adverse events. Strategies that facilitate ethical decision making and reflection and encourage openness and learning from adverse events would likely improve patient safety and enhance practitioner wellbeing. Further research is needed to develop and implement support for practitioners who experience ethical challenges in relation to adverse events.

RESUMO

INTRODUCTION: Radiation therapy (RT) can benefit approximately 50% of cancer patients and contribute to 40% of all cancer cures, yet its utilisation in cancer is low globally. Several factors contribute to this including perceived inconvenience related to accessing and utilising RT. To quantitatively assess the latter, a new tool - the Radiation therapy-related Inconvenience Questionnaire (RIQ) - was developed. This study aimed to pre-test the RIQ and explore barriers and facilitators to implementing it in routine clinical practice and clinical trials. METHODS: Semi-structured cognitive interviews were conducted with patients undertaking RT, recruited via three hospitals to examine content validity, acceptability, and comprehensibility of the RIQ. Interviews identified inconsistencies, relevance, and clarity of items. Semi-structured interviews with healthcare professionals involved in the delivery of care to individuals undertaking RT explored barriers and facilitators to routine usage. Thematic analysis was used to identify themes. RESULTS: Patients (N = 15) identified problems in content, instructions, layout, length, and response options; consequently, 25 items were revised and eight removed, resulting in a final 29-item questionnaire. Clinicians identified staff- and patient-specific barriers to implementing RIQ in clinical practice. Perceived facilitators included the following: (a) workplace factors, (b) mode of administration, and (c) imparting knowledge. CONCLUSION: This study demonstrated acceptability and comprehensibility of the 29-item RIQ amongst cancer patients undertaking RT and treating clinicians. The next phase will evaluate the RIQ's measurement properties in a larger clinical study. The barriers and facilitators identified can guide future implementation of RIQ in clinical practice and clinical trials.

RESUMO

INTRODUCTION: Pelvic exenteration (PE) surgery represents the only potentially curative treatment option for patients with locally advanced or recurrent rectal cancer (LARRC). Given the potential morbidity, whether or not PE should be recommended for an individual patient presents a major decisional conflict. This study aims to identify the outcomes of PE for which there is consensus among patients, carers and clinicians regarding their importance in guiding treatment decision-making, and to develop a risk prediction tool which predicts these outcomes. METHODS AND ANALYSIS: This study will be conducted at a specialist PE centre, and employ a mixed-methods study design, divided into three distinct phases. In phase 1, outcomes of PE will be identified through a comprehensive systematic review of the literature (phase 1a), followed by exploration of the experiences of individuals who have undergone PE for LARRC and their carers (phase 1b, target sample size 10-20 patients and 5-10 carers). In phase 2, a survey of patients, their carers and clinicians will be conducted using Delphi methodology to explore consensus around the outcomes of highest priority and the level of influence each outcome should have on treatment decision-making. In phase 3 a, risk prediction tool will be developed using data from a single PE referral centre (estimated sample size 500 patients) to predict priority outcomes using multivariate modelling, and externally validated using data from an international PE collaboration. ETHICS AND DISSEMINATION: Ethical approval has been granted for phases 1 and 2 (X22-0422 and 2022/ETH02659) and for maintenance of the database used in phase 3 (X13-0283 and HREC/13/RPAH/504). Informed consent will be obtained from participants in phases 1b and 2; a waiver of consent for secondary use of data in phase 3 will be sought. Study results will be submitted for publication in international and/or national peer reviewed journals. PROSPERO REGISTRATION NUMBER: CRD42022351909.

RESUMO

BACKGROUND: Injectable non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed to queens undergoing ovariohysterectomy (OVH), but the requirement for postoperative administration is unclear and practices vary. Existing studies assessing efficacy rely on pain scoring by experienced clinicians. However, following OVH, most cats are discharged within hours of recovery. METHODS: Cats undergoing OVH were randomly assigned to two treatment groups: MEL and ROB. Cats in the MEL group (n = 76) received meloxicam (0.2 mg/kg) and those in the ROB group (n = 65) received robenacoxib (2 mg/kg). Owners were contacted by a blinded assessor 3 days postoperatively and asked to identify physical or behavioural changes and to assign pain scores using a numerical rating scale. RESULTS: More cats in the ROB group displayed abnormal behaviours than cats in the MEL group (p = 0.03). Most owners assigned a pain score of 0 (72%) (n = 101), but pain scores were significantly higher in the ROB group than in the MEL group (p = 0.005). LIMITATION: Methods of owner assessment of pain in cats have not been validated. CONCLUSIONS: Both meloxicam and robenacoxib are effective in controlling postoperative pain. Meloxicam may have improved efficacy in certain patient populations. Applying a blanket approach to prescribing NSAIDs to cats undergoing OVH postoperatively may not be necessary. This has safety, environmental and cost implications.

RESUMO

INTRODUCTION: Colorectal cancer (CRC) is prevalent in the developed world, with unhealthy lifestyles and diet contributing to rising incidence. Advances in effective screening, diagnosis, and treatments have led to improved survival rates, but CRC survivors suffer poorer long-term gastrointestinal consequences than the general population. However, the current state of clinical practice around provision of health services and treatment options remains unclear. PURPOSE: We aimed to identify what supportive care interventions are available to manage gastrointestinal (GI) symptoms for CRC survivors. METHODS: We searched Cochrane Central Register of Controlled Trials, Embase, MEDLINE, PsycINFO, and CINAHL from 2000 to April 2022 for resources, services, programs, or interventions to address GI symptoms and functional outcomes in CRC. We extracted information about characteristics of supportive care interventions, the study design, and sample characteristics from included studies, and performed a narrative synthesis RESULTS: Of 3807 papers retrieved, seven met the eligibility criteria. Types of interventions for managing or improving GI symptoms included two rehabilitation, one exercise, one educational, one dietary, and one pharmacological. Pelvic floor muscle exercise may help to resolve GI symptoms more quickly in the post-operative recovery phase. Survivors may also benefit from rehabilitation programs through improved self-management strategies, especially administered soon after completing primary treatment. CONCLUSIONS/IMPLICATIONS FOR CANCER SURVIVORS: Despite a high prevalence and burden of GI symptoms post-treatment, there is limited evidence for supportive care interventions to help manage or alleviate these symptoms. More, large-scale randomized controlled trials are needed to identify effective interventions for managing GI symptoms that occur post-treatment.

RESUMO

The article investigates asynchronous narrative research via email as a flexible and agentic method of collecting data that may empower female participants. A case study was used that focused on the challenges for academic and professional women at an Australian regional university. Twenty-one women responded by email to a range of questions about working conditions and career progression. The data demonstrated that participants found this methodology empowering, encouraging agentic behaviour as they could respond at a time that suited them and in as much detail as they desired. They could also leave their narratives and return to them after some reflection. While lacking the non-verbal markers that often add to meanings in face-to-face interviews, the participants' writing gave voice and form to their lived experience that has been missing from academic literature. This research method may be vital in the continuing COVID-19 environment where it can be difficult to access geographically dispersed participants.

RESUMO

Insulin secretion from pancreatic ß cells is essential to the maintenance of glucose homeostasis. Defects in this process result in diabetes. Identifying genetic regulators that impair insulin secretion is crucial for the identification of novel therapeutic targets. Here, we show that reduction of ZNF148 in human islets, and its deletion in stem cell-derived ß cells (SC-ß cells), enhances insulin secretion. Transcriptomics of ZNF148-deficient SC-ß cells identifies increased expression of annexin and S100 genes whose proteins form tetrameric complexes involved in regulation of insulin vesicle trafficking and exocytosis. ZNF148 in SC-ß cells prevents translocation of annexin A2 from the nucleus to its functional place at the cell membrane via direct repression of S100A16 expression. These findings point to ZNF148 as a regulator of annexin-S100 complexes in human ß cells and suggest that suppression of ZNF148 may provide a novel therapeutic strategy to enhance insulin secretion.

RESUMO

Phosphorus (P) budgets can be useful tools for understanding nutrient cycling and quantifying the effectiveness of nutrient management planning and policies; however, uncertainties in agricultural nutrient budgets are not often quantitatively assessed. The objective of this study was to evaluate uncertainty in P fluxes (fertilizer/manure application, atmospheric deposition, irrigation, crop removal, surface runoff, and leachate) and the propagation of these uncertainties to annual P budgets. Data from 56 cropping systems in the P-FLUX database, which spans diverse rotations and landscapes across the United States and Canada, were evaluated. Results showed that across cropping systems, average annual P budget was 22.4 kg P ha-1 (range = -32.7 to 340.6 kg P ha-1 ), with an average uncertainty of 13.1 kg P ha-1 (range = 1.0-87.1 kg P ha-1 ). Fertilizer/manure application and crop removal were the largest P fluxes across cropping systems and, as a result, accounted for the largest fraction of uncertainty in annual budgets (61% and 37%, respectively). Remaining fluxes individually accounted for <2% of the budget uncertainty. Uncertainties were large enough that determining whether P was increasing, decreasing, or not changing was inconclusive in 39% of the budgets evaluated. Findings indicate that more careful and/or direct measurements of inputs, outputs, and stocks are needed. Recommendations for minimizing uncertainty in P budgets based on the results of the study were developed. Quantifying, communicating, and constraining uncertainty in budgets among production systems and multiple geographies is critical for engaging stakeholders, developing local and national strategies for P reduction, and informing policy.

RESUMO

There is a wealth of data indicating human bone marrow contains skeletal stem cells (SSC) with the capacity for osteogenic, chondrogenic and adipogenic differentiation. However, current methods to isolate SSCs are restricted by the lack of a defined marker, limiting understanding of SSC fate, immunophenotype, function and clinical application. The current study applied single-cell RNA-sequencing to profile human adult bone marrow populations from 11 donors and identified novel targets for SSC enrichment. Spherical nucleic acids were used to detect these mRNA targets in SSCs. This methodology was able to rapidly isolate potential SSCs found at a frequency of <1 in 1,000,000 in human bone marrow, with the capacity for tri-lineage differentiation in vitro and ectopic bone formation in vivo. The current studies detail the development of a platform to advance SSC enrichment from human bone marrow, offering an invaluable resource for further SSC characterisation, with significant therapeutic impact therein.
