Soliciting additional concerns in the primary care consultation and the utility of a brief communication intervention to aid solicitation: A qualitative study

Objective To investigate the perspectives of general practitioners (GPs) on the practice of soliciting additional concerns (ACs) and the acceptability and utility of two brief interventions (prompts) designed to aid the solicitation. Methods Eighteen GPs participating in a feasibility randomised controlled trial were interviewed. Interviews were semi-structured and audio-recorded. Data were analysed using a Framework Approach. Results Participants perceived eliciting ACs as important for: reducing the need for multiple visits, identifying serious illness early, and increasing patient and GP satisfaction. GPs found the prompts easy to use and some continued their use after the study had ended to aid time management. Others noted similarities between the intervention and their usual practice. Nevertheless, soliciting ACs in every consultation was not unanimously supported. Conclusion The prompts were acceptable to GPs within a trial context, but there was disagreement as to whether ACs should be solicited routinely. Some GPs considered the intervention to aid their prioritisation efficiency within consultations. Practice implications Some GPs will find prompts which encourage ACs to be solicited early in the consultation enable them to better organise priorities and manage time-limited consultations more effectively.

An exploration through interview and drawings of the experiences of patients diagnosed with oral cancer across their cancer trajectory

Background: The treatment of oral cancer is complex and lengthy. Curative treatment implies a combination of surgery, radiotherapy and chemotherapy. The main goal of treatment is to guarantee long-term tumour free survival with as little functional and cosmetic damage. Despite progress in developing these strategies, cancers of the oral cavity continue to have high mortality rates that have not improved dramatically over the past ten years. Aim: The aim of this study was to uniquely explore the dynamic changes in the physical, psychological, social and existential experiences of newly diagnosed patients with oral cancer at two points across their cancer illness trajectory i.e. at the time of diagnosis and at the end of treatment. Methodology: A qualitative prospective longitudinal design was employed. Non-probability purposive sampling allowed the recruitment of 10 participants. The principal data collection method used was a digital audio taped semi-structured interview along with drawings produced by the participants. Analysis: Data was analysed using latent content analyses. Summary: Three ‘dynamic’ themes, physical, psychosocial and existential experiences were revealed that interact and influence each other in a complex and compound whole. These experiences are present at different degrees and throughout the entire trajectory of care. Patients have a number of specific concerns and challenges that cannot be compartmentalised into unitary or discrete aspects of their daily lives. Conclusion & Implications: An understanding of the patient’s experience of their illness at all stages of the disease trajectory, is essential to inform service providers’ decision making if the delivery of care is to be client centred. Dynamic and fluctuating changes in the patient’s personal experience of the cancer journey require dynamic, energetic and timely input from health care professionals.

Guidance for laboratories performing molecular pathology for cancer patients

Molecular testing is becoming an important part of the diagnosis of any patient with cancer. The challenge to laboratories is to meet this need, using reliable methods and processes to ensure that patients receive a timely and accurate report on which their treatment will be based. The aim of this paper is to provide minimum requirements for the management of molecular pathology laboratories. This general guidance should be augmented by the specific guidance available for different tumour types and tests. Preanalytical considerations are important, and careful consideration of the way in which specimens are obtained and reach the laboratory is necessary. Sample receipt and handling follow standard operating procedures, but some alterations may be necessary if molecular testing is to be performed, for instance to control tissue fixation. DNA and RNA extraction can be standardised and should be checked for quality and quantity of output on a regular basis. The choice of analytical method(s) depends on clinical requirements, desired turnaround time, and expertise available. Internal quality control, regular internal audit of the whole testing process, laboratory accreditation, and continual participation in external quality assessment schemes are prerequisites for delivery of a reliable service. A molecular pathology report should accurately convey the information the clinician needs to treat the patient with sufficient information to allow for correct interpretation of the result. Molecular pathology is developing rapidly, and further detailed evidence-based recommendations are required for many of the topics covered here.

Helping medical students to acquire a deeper understanding of truth-telling.

PROBLEM: Truth-telling is an important component of respect for patients' self-determination, but in the context of breaking bad news, it is also a distressing and difficult task. INTERVENTION: We investigated the long-term influence of a simulated patient-based teaching intervention, integrating learning objectives in communication skills and ethics into students' attitudes and concerns regarding truth-telling. We followed two cohorts of medical students from the preclinical third year to their clinical rotations (fifth year). Open-ended responses were analysed to explore medical students' reported difficulties in breaking bad news. CONTEXT: This intervention was implemented during the last preclinical year of a problem-based medical curriculum, in collaboration between the doctor-patient communication and ethics programs. OUTCOME: Over time, concerns such as empathy and truthfulness shifted from a personal to a relational focus. Whereas 'truthfulness' was a concern for the content of the message, 'truth-telling' included concerns on how information was communicated and how realistically it was received. Truth-telling required empathy, adaptation to the patient, and appropriate management of emotions, both for the patient's welfare and for a realistic understanding of the situation. LESSONS LEARNED: Our study confirms that an intervention confronting students with a realistic situation succeeds in making them more aware of the real issues of truth-telling. Medical students deepened their reflection over time, acquiring a deeper understanding of the relational dimension of values such as truth-telling, and honing their view of empathy.

Immuno-oncology of human prostate cancer : phenotypical characterization and study of the tumor-derived, androgen-regulated immunosuppressive microenvironment

Le cancer de la prostate est le cancer le plus fréquemment diagnostiqué chez les hommes canadiens et la troisième cause de décès relié au cancer. Lorsque diagnostiqué à un stade précoce de la maladie, le cancer de la prostate est traité de manière curative par chirurgie et radiothérapie. Par contre, les thérapies actuelles ne peuvent éradiquer la maladie lorsqu’elle progresse à des stades avancés. Ces thérapies, comme la chimiothérapie et l’hormonothérapie, demeurent donc palliatives. Il est primordial d’optimiser de nouvelles thérapies visant l’élimination des cellules cancéreuses chez les patients atteints des stades avancés de la maladie. Une de ces nouvelles options thérapeutiques est l’immunothérapie. L’immunothérapie du cancer a fait des progrès considérables durant les dernières années. Cependant, les avancements encourageants obtenus lors d’essais précliniques ne se sont pas encore traduits en des résultats cliniques significatifs. En ce qui concerne le cancer de la prostate, les résultats négligeables suivants des interventions immunothérapeutiques peuvent être causés par le fait que la plupart des études sur le microenvironnement immunologique furent effectuées chez des modèles animaux. De plus la majorité des études sur l’immunologie tumorale humaine furent effectuées chez des patients atteints d’autres cancers, tels que le mélanome, et non chez les patients atteints du cancer de la prostate. Donc, le but central de cette thèse de doctorat est d’étudier le microenvironnement immunologique chez les patients atteints du cancer de la prostate afin de mieux définir les impacts de la tumeur sur le développement de la réponse immunitaire antitumorale. Pour réaliser ce projet, nous avons établi deux principaux objectifs de travail : (i) la caractérisation précise des populations des cellules immunitaires infiltrant la tumeur primaire et les ganglions métastatiques chez les patients atteints du cancer de la prostate; (ii) l’identification et l’étude des mécanismes immunosuppressifs exprimés par les cellules cancéreuses de la prostate. Les résultats présentés dans cette thèse démontrent que la progression du cancer de la prostate est associée au développement d’un microenvironnement immunosuppressif qui, en partie, est régulé par la présence des androgènes. L’étude initiale avait comme but la caractérisation du microenvironnement immunologique des ganglions drainant la tumeur chez des patients du cancer de la prostate. Les résultats présentés dans le chapitre III nous a permis de démontrer que les ganglions métastatiques comportent des signes cellulaires et histopathologiques associés à une faible réactivité immunologique. Cette immunosuppression ganglionnaire semble dépendre de la présence des cellules métastatiques puisque des différences immunologiques notables existent entre les ganglions non-métastatiques et métastatiques chez un même patient. La progression du cancer de la prostate semble donc associée au développement d’une immunosuppression affectant les ganglions drainant la tumeur primaire. Par la suite, nous nous sommes intéressés à l’impact de la thérapie par déplétion des androgènes (TDA) sur le microenvironnement immunologique de la tumeur primaire. La TDA est associée à une augmentation marquée de l’inflammation prostatique. De plus, les protocoles d’immunothérapies pour le cancer de la prostate actuellement évalués en phase clinique sont dirigés aux patients hormonoréfractaires ayant subi et échoué la thérapie. Cependant, peu d’information existe sur la nature de l’infiltrat de cellules immunes chez les patients castrés. Il est donc essentiel de connaître la nature de cet infiltrat afin de savoir si celui-ci peut répondre de manière favorable à une intervention immunothérapeutique. Dans le chapitre IV, je présente les résultats sur l’abondance des cellules immunes infiltrant la tumeur primaire suivant la TDA. Chez les patients castrés, les densités de lymphocytes T CD3+ et CD8+ ainsi que des macrophages CD68+ sont plus importantes que chez les patients contrôles. Nous avons également observé une corrélation entre la densité de cellules NK et une diminution du risque de progression de la maladie (rechute biochimique). Inversement, une forte infiltration de macrophages est associée à un plus haut risque de progression. Conjointement, durant cette étude, nous avons développé une nouvelle approche informatisée permettant la standardisation de la quantification de l’infiltrat de cellules immunes dans les échantillons pathologiques. Cette approche facilitera la comparaison d’études indépendantes sur la densité de l’infiltrat immun. Ces résultats nous ont donc permis de confirmer que les effets pro-inflammatoires de la TDA chez les patients du cancer de la prostate ciblaient spécifiquement les lymphocytes T et les macrophages. L’hypothèse intéressante découlant de cette étude est que les androgènes pourraient réguler l’expression de mécanismes immunosuppressifs dans la tumeur primaire. Dans le chapitre V, nous avons donc étudié l’expression de mécanismes immunosuppressifs par les cellules cancéreuses du cancer de la prostate ainsi que leur régulation par les androgènes. Notre analyse démontre que les androgènes augmentent l’expression de molécules à propriétés immunosuppressives telles que l’arginase I et l’arginase II. Cette surexpression dépend de l’activité du récepteur aux androgènes. Chez les patients castrés, l’expression de l’arginase II était diminuée suggérant une régulation androgénique in vivo. Nous avons observé que l’arginase I et l’arginase II participent à la prolifération des cellules du cancer de la prostate ainsi qu’à leur potentiel immunosuppressif. Finalement, nous avons découvert que l’expression de l’interleukin-8 était aussi régulée par les androgènes. De plus, l’interleukin-8, indépendamment des androgènes, augmente l’expression de l’arginase II. Ces résultats confirment que les androgènes participent au développement d’une microenvironnement immunosuppressif dans le cancer de la prostate en régulant l’expression de l’arginase I, l’arginase II et l’interleukin-8. En conclusion, les résultats présentés dans cette thèse témoignent du caractère unique du microenvironnement immunologique chez les patients atteints du cancer de la prostate. Nos travaux ont également permis d’établir de nouvelles techniques basées sur des logiciels d’analyse d’image afin de mieux comprendre le dialogue entre la tumeur et le système immunitaire chez les patients. Approfondir les connaissances sur les mécanismes de régulation du microenvironnement immunologique chez les patients atteint du cancer de la prostate permettra d’optimiser des immunothérapies mieux adaptées à éradiquer cette maladie.

Current status of knowledge about suicide in people with cancer

Aim: To review the current knowledge about suicide in cancer patients. Method: We searchedspecialized databases using keywords for articles published in the last two decades (1990-2010),and compiled and reviewed them in order to: indicate the prevalence of suicide in cancer patientsworldwide and in Colombia, differentiating the data by sex and age; establish the types of cancerthat are associated with suicide, identify risk factors for committing or considering suicide andpresent the strategies of professional and psychological intervention directed at cancer patientswith suicidal ideation and suicide attempts. The present article is a review of the information on thesubject. Results: We found that: in cancer patients, the suicide rate is two times higher thanin the general population; depression, suicidal ideation and location of cancer are some of therisk factors for suicide, and there is a lack of published guidelines for professional managementof the suicidal patient with cancer. Conclusion: The need to carry out research on the topic ofsuicide in cancer patients was established.

Low cost brain-computer interface: first results

Brain-Computer Interfacing (BCI) has been previously demonstrated to restore patient communication, meeting with varying degrees of success. Due to the nature of the equipment traditionally used in BCI experimentation (the electroencephalograph) it is mostly conned to clinical and research environments. The required medical safety standards, subsequent cost of equipment and its application/training times are all issues that need to be resolved if BCIs are to be taken out of the lab/clinic and delivered to the home market. The results in this paper demonstrate a system developed with a low cost medical grade EEG amplier unit in conjunction with the open source BCI2000 software suite thus constructing the cheapest per electrode system available, meeting rigorous clinical safety standards. Discussion of the future of this technology and future work concerning this platform are also introduced.

Pragmatic oriented data interoperability for smart healthcare information systems

Smart healthcare is a complex domain for systems integration due to human and technical factors and heterogeneous data sources involved. As a part of smart city, it is such a complex area where clinical functions require smartness of multi-systems collaborations for effective communications among departments, and radiology is one of the areas highly relies on intelligent information integration and communication. Therefore, it faces many challenges regarding integration and its interoperability such as information collision, heterogeneous data sources, policy obstacles, and procedure mismanagement. The purpose of this study is to conduct an analysis of data, semantic, and pragmatic interoperability of systems integration in radiology department, and to develop a pragmatic interoperability framework for guiding the integration. We select an on-going project at a local hospital for undertaking our case study. The project is to achieve data sharing and interoperability among Radiology Information Systems (RIS), Electronic Patient Record (EPR), and Picture Archiving and Communication Systems (PACS). Qualitative data collection and analysis methods are used. The data sources consisted of documentation including publications and internal working papers, one year of non-participant observations and 37 interviews with radiologists, clinicians, directors of IT services, referring clinicians, radiographers, receptionists and secretary. We identified four primary phases of data analysis process for the case study: requirements and barriers identification, integration approach, interoperability measurements, and knowledge foundations. Each phase is discussed and supported by qualitative data. Through the analysis we also develop a pragmatic interoperability framework that summaries the empirical findings and proposes recommendations for guiding the integration in the radiology context.

Le reti in Sanità

Il presente lavoro di ricerca intende analizzare l’importanza dei modelli organizzativi a reti per rispondere alla sfida della complessità del momento storico, politico, sociologico, economico; in modo particolare in Sanità per rispondere all’esigenza di mettere al centro la persona nel percorso di cura ed ottenere una migliore integrazione delle cure. Sebbene i vantaggi delle reti siano bene descritti in letteratura sono ancora pochi gli studi nell’ambito della valutazione. Il caso di studio ha riguardato la rete oncologica romagnola così come percepita dagli informatori chiave, dagli operatori (medici, infermieri, amministrativi) e dalle persone con esperienza di tumore. Dall’analisi degli informatori chiave emerge forte che la rete nasce per dare risposte di qualità ai bisogni dei pazienti, mentre per gli operatori quanto sia importante la dimensione delle relazioni umane e avere valori condivisi per raggiungere obiettivi di efficacia e qualità delle cure. Per quanto riguarda invece la percezione delle persone con esperienza di tumore si rileva quanto sia importante l’appropriatezza della traiettoria di cura nonché l’avere continuità in un percorso, già di per sé difficile, oltre all’importanza dell’umanizzazione dei servizi e della corretta comunicazione medico paziente.

Cellular telephone use and time trends in brain tumour mortality in Switzerland from 1969 to 2002

A rising concern exists that with the widespread use of mobile communication technologies, the incidence of brain tumours may increase. On the basis of data from the Swiss national mortality registry from 1969 to 2002, annual age-standardized brain tumour mortality rates per 100,000 person-years were calculated using the European standard population. Time trend analyses were performed by the Poisson regression for six different age groups in men and women separately. The study period was divided into two intervals: before and after 1987, when the analogue mobile technology was introduced in Switzerland. Age-standardized brain tumour mortality rates ranged between 3.7 and 6.7 for men and 2.5 and 4.4 for women per 100,000 person-years. For the whole study period, a significant increase in brain tumour mortality was observed for men and women in the older age groups (60-74 and 75+ years) but not in the younger ones in whom mobile phone use was more prevalent. Time trend analyses restricted to data from 1987 onwards revealed relatively stable brain tumour mortality rates in all age groups. For instance, the annual change in brain tumour mortality rate for the 45-59-year age group was -0.3% (95% confidence interval: -1.7; 1.1) for men and -0.4% (95% confidence interval:-2.2; 1.3) for women. We conclude that after the introduction of mobile phone technology in Switzerland, brain tumour mortality rates remained stable in all age groups. Our results suggest that mobile phone use is not a strong risk factor in the short term for mortality from brain tumours. Ecological analyses like this, however, are limited in their ability to reveal potentially small increases in risk for diseases with a long latency period.

Understanding treatment-related symptoms, symptom management techniques, and symptom management self-efficacy in a sample of non-muscle invasive bladder cancer patients

The current literature available on bladder cancer symptom management from the perspective of the patients themselves is limited. There is also limited psychosocial research specific to bladder cancer patients and no previous studies have developed and validated measures for bladder cancer patients’ symptom management self-efficacy. The purpose of this study was to investigate non-muscle invasive bladder cancer patients’ health related quality of life through two main study objectives: (1) to describe the treatment related symptoms, reported effectiveness of symptom-management techniques, and the advice a sample of non-muscle invasive bladder cancer patients would convey to physicians and future patients; and (2) to evaluate Lepore’s symptom management self-efficacy measure on a sample of non-muscle invasive bladder cancer patients. Methods. A total of twelve (n=12) non-muscle invasive bladder cancer patients participated in an in-depth interview and a sample of 46 (n=4) non-muscle invasive bladder cancer patients participated in the symptom-management self-efficacy survey. Results. A total of five symptom categories emerged for the participants’ 59 reported symptoms. Four symptom management categories emerged out of the 71 reported techniques. A total of 62% of the participants’ treatment related symptom-management techniques were reported as effective in managing their treatment-related symptoms. Five advice categories emerged out of the in-depth interviews: service delivery; medical advice; physician-patient communication; encouragement; and no advice. An exploratory factor analysis indicated a single-factor structure for the total population and a multiple factor structure for three subgroups: all males, married males, and all married participants. Conclusion. These findings can inform physicians and patients of effective symptom-management techniques thus improving patients’ health-related quality of life. The advice these patients’ impart can improve service-delivery and patient education.^

Creating a Web-accessible, point-of-care, team-based information system (PoinTIS): the librarian as publisher*

The Internet has created new opportunities for librarians to develop information systems that are readily accessible at the point of care. This paper describes the multiyear process used to justify, fund, design, develop, promote, and evaluate a rehabilitation prototype of a point-of-care, team-based information system (PoinTIS) and train health care providers to use this prototype for their spinal cord injury and traumatic brain injury patient care and education activities. PoinTIS is a successful model for librarians in the twenty-first century to serve as publishers of information created or used by their parent organizations and to respond to the opportunities for information dissemination provided by recent technological advances.

Non-pharmacological interventions for cognitive impairment due to systemic cancer treatment (Review)

Background

It is estimated that up to 75% of cancer survivors may experience cognitive impairment as a result of cancer treatment and given the increasing size of the cancer survivor population, the number of affected people is set to rise considerably in coming years. There is a need, therefore, to identify effective, non-pharmacological interventions for maintaining cognitive function or ameliorating cognitive impairment among people with a previous cancer diagnosis.
Objectives

To evaluate the cognitive effects, non-cognitive effects, duration and safety of non-pharmacological interventions among cancer patients targeted at maintaining cognitive function or ameliorating cognitive impairment as a result of cancer or receipt of systemic cancer treatment (i.e. chemotherapy or hormonal therapies in isolation or combination with other treatments).
Search methods

We searched the Cochrane Centre Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PUBMED, Cumulative Index of Nursing and Allied Health Literature (CINAHL) and PsycINFO databases. We also searched registries of ongoing trials and grey literature including theses, dissertations and conference proceedings. Searches were conducted for articles published from 1980 to 29 September 2015.
Selection criteria

Randomised controlled trials (RCTs) of non-pharmacological interventions to improve cognitive impairment or to maintain cognitive functioning among survivors of adult-onset cancers who have completed systemic cancer therapy (in isolation or combination with other treatments) were eligible. Studies among individuals continuing to receive hormonal therapy were included. We excluded interventions targeted at cancer survivors with central nervous system (CNS) tumours or metastases, non-melanoma skin cancer or those who had received cranial radiation or, were from nursing or care home settings. Language restrictions were not applied.
Data collection and analysis

Author pairs independently screened, selected, extracted data and rated the risk of bias of studies. We were unable to conduct planned meta-analyses due to heterogeneity in the type of interventions and outcomes, with the exception of compensatory strategy training interventions for which we pooled data for mental and physical well-being outcomes. We report a narrative synthesis of intervention effectiveness for other outcomes.
Main results

Five RCTs describing six interventions (comprising a total of 235 participants) met the eligibility criteria for the review. Two trials of computer-assisted cognitive training interventions (n = 100), two of compensatory strategy training interventions (n = 95), one of meditation (n = 47) and one of physical activity intervention (n = 19) were identified. Each study focused on breast cancer survivors. All five studies were rated as having a high risk of bias. Data for our primary outcome of interest, cognitive function were not amenable to being pooled statistically. Cognitive training demonstrated beneficial effects on objectively assessed cognitive function (including processing speed, executive functions, cognitive flexibility, language, delayed- and immediate- memory), subjectively reported cognitive function and mental well-being. Compensatory strategy training demonstrated improvements on objectively assessed delayed-, immediate- and verbal-memory, self-reported cognitive function and spiritual quality of life (QoL). The meta-analyses of two RCTs (95 participants) did not show a beneficial effect from compensatory strategy training on physical well-being immediately (standardised mean difference (SMD) 0.12, 95% confidence interval (CI) -0.59 to 0.83; I2= 67%) or two months post-intervention (SMD - 0.21, 95% CI -0.89 to 0.47; I2 = 63%) or on mental well-being two months post-intervention (SMD -0.38, 95% CI -1.10 to 0.34; I2 = 67%). Lower mental well-being immediately post-intervention appeared to be observed in patients who received compensatory strategy training compared to wait-list controls (SMD -0.57, 95% CI -0.98 to -0.16; I2 = 0%). We assessed the assembled studies using GRADE for physical and mental health outcomes and this evidence was rated to be low quality and, therefore findings should be interpreted with caution. Evidence for physical activity and meditation interventions on cognitive outcomes is unclear.
Authors' conclusions

Overall, the, albeit low-quality evidence may be interpreted to suggest that non-pharmacological interventions may have the potential to reduce the risk of, or ameliorate, cognitive impairment following systemic cancer treatment. Larger, multi-site studies including an appropriate, active attentional control group, as well as consideration of functional outcomes (e.g. activities of daily living) are required in order to come to firmer conclusions about the benefits or otherwise of this intervention approach. There is also a need to conduct research into cognitive impairment among cancer patient groups other than women with breast cancer.
