Drugs targeting the bone microenvironment: new therapeutic tools in Ewing's sarcoma?
Introduction: Ewing's sarcoma (ES) is the second most frequent malignant primary bone tumour in children, adolescents and young adults. The overall survival is 60 – 70% at 5 years but still very poor for patients with metastases, disease relapse or for those not responding to chemotherapy. For these high risk patients, new therapeutic approaches are needed beyond conventional therapies (chemotherapy, surgery and radiation) such as targeted therapies.
Areas covered: Transcriptomic and genomic analyses in ES have revealed alterations in genes that control signalling pathways involved in many other cancer types. To set up more specific approaches, it is reasonable to think that the particular microenvironment of these bone tumours is essential for their initiation and progression, including in ES. To support this hypothesis, preclinical studies using drugs targeting bone cells (bisphosphonate zoledronate, anti-receptor activator of NF-κB ligand strategies) showed promising results in animal models. This review will discuss the new targeted therapeutic options in ES, focusing more particularly on the ones modulating the bone microenvironment.
Expert opinion: Targeting the microenvironment represents a new option for patients with ES. The proof-of-concept has been demonstrated in preclinical studies using relevant animal models, especially for zoledronate, which induced a strong inhibition of tumour progression in an orthotopic bone model
Serum osteoprotegerin is associated with pulse pressure in kidney transplant recipients
Pulse pressure (PP) reflects increased large artery stiffness, which is caused, in part, by arterial calcification in patients with chronic kidney disease. PP has been shown to predict both cardiovascular and cerebrovascular events in various patient populations, including kidney transplant (KTX) recipients. Osteoprotegerin (OPG) is a marker and regulator of arterial calcification, and it is related to cardiovascular survival in hemodialysis patients. Here we tested the hypothesis that OPG is associated with increased pulse pressure. We cross-sectionally analyzed the association between serum OPG and PP in a prevalent cohort of 969 KTX patients (mean age: 51 +/- 13 years, 57% male, 21% diabetics, mean eGFR 51 +/- 20 ml/min/1.73 m2). Independent associations were tested in a linear regression model adjusted for multiple covariables. PP was positively correlated with serum OPG (rho = 0.284, p < 0.001). Additionally, a positive correlation was seen between PP versus age (r = 0.358, p < 0.001), the Charlson Comorbidity Index (r = 0.232, p < 0.001), serum glucose (r = 0.172, p < 0.001), BMI (r = 0.133, p = 0.001) and serum cholesterol (r = 0.094, p = 0.003). PP was negatively correlated with serum Ca, albumin and eGFR. The association between PP and OPG remained significant after adjusting for multiple potentially relevant covariables (beta = 0.143, p < 0.001). We conclude that serum OPG is independently associated with pulse pressure in kidney transplant recipients
Confidence and competence with mathematical procedures
Confidence assessment (CA), in which students state alongside each of their answers a confidence level expressing how certain they are, has been employed successfully within higher education. However, it has not been widely explored with school pupils. This study examined how school mathematics pupils (N = 345) in five different secondary schools in England responded to the use of a CA instrument designed to incentivise the eliciting of truthful confidence ratings in the topic of directed (positive and negative) numbers. Pupils readily understood the negative marking aspect of the CA process and their facility correlated with their mean confidence with r = .546, N = 336, p < .001, indicating that pupils were generally well calibrated. Pupils’ comments indicated that the vast majority were positive about the CA approach, despite its dramatic differences from more usual assessment practices in UK schools. Some pupils felt that CA promoted deeper thinking, increased their confidence and had a potential role to play in classroom formative assessment
Incorporating health literacy in education for socially disadvantaged adults: an Australian feasibility study.
BACKGROUND: Adult education institutions have been identified as potential settings to improve health literacy and address the health inequalities that stem from limited health literacy. However, few health literacy interventions have been tested in this setting. METHODS: Feasibility study for an RCT of the UK Skilled for Health Program adapted for implementation in Australian adult education settings. Implementation at two sites with mixed methods evaluation to examine feasibility, test for change in participants' health literacy and pilot test health literacy measures. RESULTS: Twenty-two socially disadvantaged adults with low literacy participated in the program and received 80-90 hours of health literacy instruction. The program received institutional support from Australia's largest provider of vocational education and training and was feasible to implement (100 % participation; >90 % completion; high teacher satisfaction). Quantitative results showed improvements in participants' health literacy skills and confidence, with no change on a generic measure of health literacy. Qualitative analysis identified positive student and teacher engagement with course content and self-reported improvements in health knowledge, attitudes, and communication with healthcare professionals. CONCLUSIONS: Positive feasibility results support a larger RCT of the health literacy program. However, there is a need to identify better, multi-dimensional measures of health literacy in order to be able to quantify change in a larger trial. This feasibility study represents the first step in providing the high quality evidence needed to understand the way in which health literacy can be improved and health inequalities reduced through Australian adult education programs
The Role of RANK-Ligand Inhibition in Cancer: The Story of Denosumab
The bone is a very common site of metastasis in patients with advanced cancer. Skeletal metastases are most common in breast and prostate cancer, but virtually any advanced cancer may disseminate to the bone. On the basis of recent advances in the understanding of bone remodeling processes, denosumab, a fully human monoclonal antibody against RANK-L, has been developed. Phase III clinical trials have demonstrated that denosumab is well tolerated and effective in the treatment of bone loss and prevention of skeletal-related events in patients with bone metastases
Developing Verbal Health Literacy with Adult Learners Through Training in Shared Decision-Making.
BACKGROUND: Health literacy skills are often assessed in relation to written health materials; however, many important communications are in other formats, especially verbal communication with health care providers. OBJECTIVE: This qualitative study sought to examine adult learners' experiences of developing verbal health literacy skills within an Australian adult basic education program, and to explore verbal communication and shared decision-making as a constituent domain of health literacy. METHODS: We conducted a semi-structured qualitative interview study between September and November 2014 with adult learners who had participated in a single-semester health literacy program that included an integrated shared decision-making component. We analyzed interviews using the Framework method; a matrix-based approach to thematic analysis. A hybrid process of inductive and deductive coding was used to interpret raw data. KEY RESULTS: Interviewees were 22 students from six health literacy classes and ranged in age from 18 to 74 years (mean, 48.3). The majority were women (n = 15) and born outside Australia (n = 13). Health literacy was generally limited according to the Newest Vital Sign screening tool (n = 17). The health literacy program appeared to serve two key functions. First, it stimulated awareness that patients have the right to participate in decision-making concerning their treatment and care. Second, it facilitated verbal skill development across the domains of functional (e.g., communicating symptoms), communicative (e.g., asking questions to extract information about treatment options), and critical (e.g., integrating new knowledge with preferences) health literacy. CONCLUSIONS: Our findings support the conceptualization of health literacy as a modifiable health asset that is subject to change and improvement as a result of deliberate intervention. Results reinforce verbal health literacy as an important component of health literacy, and draw attention to the hierarchy of verbal skills needed for consumers to become more actively involved in decisions about their health. We present a revised model of health literacy based on our findings. [Health Literacy Research and Practice. 2017;1(4):e257-e268.]. PLAIN LANGUAGE SUMMARY: We developed a health literacy program for adults with lower literacy to help learners develop skills to talk to health care providers and share health decisions. The program was taught in Australian adult education settings. The article explores the range of health literacy skills needed for communication and decision-making in this study, and presents a model in which verbal skills are an important part of health literacy
Qualitative insights into the experience of teaching shared decision making within adult education health literacy programmes for lower-literacy learners
© 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd Background: Enhancing health literacy can play a major role in improving healthcare and health across the globe. To build higher-order (communicative/critical) health literacy skills among socially disadvantaged Australians, we developed a novel shared decision making (SDM) training programme for adults with lower literacy. The programme was delivered by trained educators within an adult basic education health literacy course. Objective: To explore the experience of teaching SDM within a health literacy programme and investigate whether communicative/critical health literacy content meets learner needs and teaching and institutional objectives. Design and participants: Qualitative interview study with 11 educators who delivered the SDM programme. Transcripts were analysed using the Framework approach; a matrix-based method of thematic analysis. Results: Teachers noted congruence in SDM content and the institutional commitment to learner empowerment in adult education. The SDM programme was seen to offer learners an alternative to their usual passive approach to healthcare decision making by raising awareness of the right to ask questions and consider alternative test/treatment options. Teachers valued a structured approach to training building on foundational skills, with language reinforcement and take-home resources, but many noted the need for additional time to develop learner understanding and cover all aspects of SDM. Challenges for adult learners included SDM terminology, computational numerical risk tasks and understanding probability concepts. Discussion and conclusions: SDM programmes can be designed in a way that both supports teachers to deliver novel health literacy content and empowers learners. Collaboration between adult education and healthcare sectors can build health literacy capacity of those most in need
Skills for Shared Decision-Making: Evaluation of a Health Literacy Program for Consumers with Lower Literacy Levels.
Background: Shared decision-making (SDM) has been found to be significantly and positively associated with improved patient outcomes. For an SDM process to occur, patients require functional, communicative, and critical health literacy (HL) skills. Objective: This study aimed to evaluate the impact of a program to improve health literacy skills for SDM in adults with lower literacy. Methods: An HL program including an SDM component (HL + SDM) and teaching of the three "AskShareKnow" questions was delivered in adult basic education settings in New South Wales, Australia. The program was evaluated using a partially cluster-randomized controlled trial comparing it to standard language, literacy, and numeracy (LLN) training. We measured the effect of these programs on (1) HL skills for SDM (conceptual knowledge, graphical literacy, health numeracy), (2) types of questions considered important for health decision-making, (3) preferences for control in decision-making, and (4) decisional conflict. We also measured AskShareKnow question recall, use, and evaluation in HL + SDM participants. Key Results: There were 308 participants from 28 classes enrolled in the study. Most participants had limited functional HL (71%) and spoke a language other than English at home (60%). In the primary analysis, the HL + SDM program compared with the standard LLN program significantly increased conceptual knowledge (19.1% difference between groups in students achieving the competence threshold; p = .018) and health numeracy (10.9% difference; p = .032), but not graphical literacy (5.8% difference; p = .896). HL + SDM participants were significantly more likely to consider it important to ask questions that would enable SDM compared to standard LLN participants who prioritized nonmedical procedural questions (all p < .01). There was no difference in preferences for control in decision-making or in decisional conflict. Among HL + SDM participants, 79% (n = 85) correctly recalled at least one of the AskShareKnow questions immediately post-intervention, and 35% (n = 29) after 6 months. Conclusions: Teaching SDM content increased participants' HL skills for SDM and changed the nature of the questions they would ask health care professionals in a way that would enable shared health decisions. [HLRP: Health Literacy Research and Practice. 2019;3(Suppl.):S58-S74.]. Plain Language Summary: We developed a health literacy program that included a shared decision-making (SDM) section. The program was delivered in adult basic education classes by trained educators and compared to standard language, literacy, and numeracy training. Teaching SDM content increased participants' health literacy skills for SDM and changed the nature of the questions they would ask health care professionals
Evaluation of an Australian Health Literacy Program Delivered in Adult Education Settings.
BACKGROUND: Adult education targeting health literacy (HL) may bring added value in the form of improved health. OBJECTIVE: This study evaluated the effects of a HL program as part of an adult education curriculum for adults with low literacy and numeracy. METHODS: This was a partial-cluster randomized controlled trial among 308 adults enrolled in basic education programs in Australia. Of the 308 participants, 141 (46%) were randomized to either the standard program (language, literacy, and numeracy [LLN]), or the HL intervention (LLN with embedded health content); the remainder (n = 167) were allocated to standard intervention programs by the education provider at the class level. The main outcomes were functional HL, self-reported confidence, patient activation, generic HL (ie, HLQ, health knowledge, and self-reported health behavior). Data were collected at baseline, immediately after, and at 6 months post-intervention. KEY RESULTS: Of the 308 participants, 71% had limited literacy and 60% spoke a language other than English at home. Both interventions benefited participants, with improvements from baseline to immediate follow up on individual-level functional HL (e.g., reading a thermometer; HL group 18.4% vs. standard group 7.2%; p = .001), confidence (HL group 0.34 vs. standard group 0.06; p = .014) and health literacy questionnaire (HLQ) subscales. At 6 months, improvements in confidence (p < .001) and some HLQ measures were retained. A consistent pattern of increased improvement in the HL program was observed compared to the standard program, although only some measures reached statistical significance: reading a food label (HL group 6.03/10 correct vs. standard group 5.49/10 correct; p = .022); confidence (p = .008); ability to actively manage health (HLQ) (p = .017), and health knowledge at 6 months (HL group 68% vs. standard group 60% correct, p = .052). HL participants reported being more likely to share course information and rated the program more useful to understand their health. CONCLUSIONS: Improving language, literacy, and numeracy generally has potential public health benefits that are retained at 6 months. Integrating health content adds further value to adult basic learning, is feasible, and potentially scalable. [HLRP: Health Literacy Research and Practice. 2019;3(Suppl.):S42-S57.]. PLAIN LANGUAGE SUMMARY: We compared the effect of an adult education-based health literacy (HL) program versus a standard language, literacy, and numeracy program on students' HL skills and psychosocial outcomes. Although students in both trial arms improved their skills, students in the HL program had better outcomes with higher HL, greater confidence, and higher health knowledge scores at 6 months
