Abstract
BACKGROUND Delirium is a distressing neuropsychiatric disorder affecting patients in palliative care. Although many delirium screening tools exist, their utility, and validation within palliative care settings has not undergone systematic review. AIM To systematically review studies that validate delirium screening tools conducted in palliative care settings. DESIGN Systematic review with narrative synthesis (PROSPERO ID: CRD42019125481). A risk of bias assessment via Quality Assessment Tool for Diagnostic Accuracy Studies-2 was performed. DATA SOURCES Five electronic databases were systematically searched (January 1, 1982-May 3, 2020). Quantitative studies validating a screening tool in adult palliative care patient populations were included. Studies involving alcohol withdrawal, critical or perioperative care were excluded. RESULTS Dual-reviewer screening of 3749 unique titles and abstracts identified 95 studies for full-text review and of these, 17 studies of 14 screening tools were included (n = 3496 patients). Data analyses revealed substantial heterogeneity in patient demographics and variability in screening and diagnostic practices that limited generalizability between study populations and care settings. A risk of bias assessment revealed methodological and reporting deficits, with only 3/17 studies at low risk of bias. CONCLUSIONS The processes of selecting a delirium screening tool and determining optimal screening practices in palliative care are complex. One tool is unlikely to fit the needs of the entire palliative care population across all palliative care settings. Further research should be directed at evaluating and/or adapting screening tools and practices to fit the needs of specific palliative care settings and populations.

Abstract
BACKGROUND Despite evidence demonstrating the utility of using Person-Centred Outcome Measures within palliative care settings, implementing them into routine practice is challenging. Most research has described barriers to, without explaining the causal mechanisms underpinning, implementation. Implementation theories explain how, why, and in which contexts specific relationships between barriers/enablers might improve implementation effectiveness but have rarely been used in palliative care outcomes research. AIM To use Normalisation Process Theory to understand and explain the causal mechanisms that underpin successful implementation of Person-Centred Outcome Measures within palliative care. DESIGN Exploratory qualitative study. Data collected through semi-structured interviews and analysed using a Framework approach. SETTING/PARTICIPANTS 63 healthcare professionals, across 11 specialist palliative care services, were purposefully sampled by role, experience, seniority, and settings (inpatient, outpatient/day therapy, home-based/community). RESULTS Seven main themes were developed, representing the causal mechanisms and relationships underpinning successful implementation of outcome measures into routine practice. Themes were: Subjectivity of measures; Frequency and version of Integrated Palliative care Outcome Scale; Training, education, and peer support; Building and sustaining community engagement; Electronic system readiness; The art of communication; Reinforcing use through demonstrating value. CONCLUSIONS Relationships influencing implementation resided at individual and organisational levels. Addressing these factors is key to driving the implementation of outcome measures into routine practice so that those using palliative care services can benefit from the systematic identification, management, and measurement of their symptoms and concerns. We provide key questions that are essential for those implementing and using outcome measures to consider in order to facilitate the integration of outcome measures into routine palliative care practice.

Abstract
UNLABELLED Palliative care is central to the role of all clinical doctors. There is variability in the amount and type of teaching about palliative care at undergraduate level. Time allocated for such teaching within the undergraduate medical curricula remains scarce. Given this, the effectiveness of palliative care teaching needs to be known. OBJECTIVES To evaluate the effectiveness of palliative care teaching for undergraduate medical students. DESIGN A systematic review was prepared according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. Screening, data extraction and quality assessment (mixed methods and Cochrane risk of bias tool) were performed in duplicate. DATA SOURCES Embase, MEDLINE, PsycINFO, Web of Science, ClinicalTrials.gov, Cochrane and grey literature in August 2019. Studies evaluating palliative care teaching interventions with medical students were included. RESULTS 1446 titles/abstracts and 122 full-text articles were screened. 19 studies were included with 3253 participants. 17 of the varied methods palliative care teaching interventions improved knowledge outcomes. The effect of teaching on clinical practice and patient outcomes was not evaluated in any study. CONCLUSIONS The majority of palliative care teaching interventions reviewed improved knowledge of medical students. The studies did not show one type of teaching method to be better than others, and thus no 'best way' to provide teaching about palliative care was identified. High quality, comparative research is needed to further understand effectiveness of palliative care teaching on patient care/clinical practice/outcomes in the short-term and longer-term.

Abstract
BACKGROUND Chronic breathlessness is a disabling syndrome that profoundly impacts patients' and caregivers' lives. Driving is important for most people, including those with advanced disease. Regular, low-dose, sustained-release morphine safely reduces breathlessness, but little is known about its impact on driving. AIM To understand patients' and caregivers' (1) perspectives and experiences of driving with chronic breathlessness; and (2) perceived impact of regular, low-dose, sustained-release morphine on driving. DESIGN A qualitative study embedded in a pragmatic, phase III, randomised, placebo-controlled trial of low-dose, sustained-release morphine (⩽32 mg/24 h) for chronic breathlessness. Semi-structured interviews were conducted immediately after participants withdrew or completed the randomised, placebo-controlled trial. Informed by grounded theory, a constant comparative approach to analysis was adopted. SETTING/PARTICIPANTS Participants were recruited from an outpatients palliative care service in Adelaide, Australia. Participants included patients (n = 13) with severe breathlessness associated with chronic obstructive pulmonary disease and their caregivers (n = 9). RESULTS Participants were interviewed at home. Eleven received morphine 8-32 mg. Three themes emerged: (1) independence; (2) breathlessness' impact on driving; and (3) driving while taking regular, low-dose, sustained-release morphine. CONCLUSION Driving contributed to a sense of identity and independence. Being able to drive increased the physical and social space available to patients and caregivers, their social engagement and well-being. Patients reported breathlessness at rest may impair driving skills, while the introduction of sustained-release morphine seemed to have no self-reported impact on driving. Investigating this last perception objectively, especially in terms of safety, is the subject of ongoing work.

Abstract
OBJECTIVES Delirium is common and distressing in palliative care settings. This survey aims to describe current practice regarding delirium identification in specialist palliative care units (SPCU), such as inpatient hospices, in the UK. METHODS An 18-item anonymous online survey was distributed by Hospice UK to their network of clinical leads (n=223), and to their research mailing list (n=228). The survey was also sent to the chair of the Hospice UK executive clinical leads forum for direct dissemination to forum representatives (n=20). Clinical leads and forum representatives were asked to distribute the survey to healthcare staff in their SPCUs. RESULTS 220 SPCU staff (48% nurses; 31% doctors; 10% healthcare assistants) completed the survey. Approximately half reported using clinical judgement alone to screen (97/204; 48%) and/or diagnose (124/220; 56%) delirium. Over a third used an assessment tool to screen for delirium (76/204; 37%). The majority (150/220; 68%) reported screening in response to clinical symptoms, while few reported routine on-admission (11/220; 5%) or daily-during-admission (12/220; 6%) screening. Most respondents had received some training on delirium (137/220; 62%). However, 130/220 (59%) said their SPCU did not have a training programme for delirium screening and only 79/220 (36%) reported that their SPCU had delirium clinical guidelines. The main barriers to routine screening included: lack of delirium training, lack of guidelines and complexity of patient's conditions. CONCLUSION There is variation in practice for delirium screening and diagnosis in SPCUs. Clinical guidelines for delirium, including consensus on which screening tools to use, are needed for this setting.

Abstract
BACKGROUND Pain of a moderate or severe intensity affects over half of patients with advanced cancer and remains undertreated in at least one-third of these patients. AIM The aim of this study was to provide a pragmatic overview of the evidence supporting the use of interventions in pain management in advanced cancer and to identify where encouraging preliminary results are demonstrated but further research is required. DESIGN A scoping review approach was used to examine the evidence supporting the use of guideline-recommended interventions in pain management practice. DATA SOURCES National or international guidelines were selected if they described pain management in adult cancer patients and were written within the last 5 years in English. The Cochrane Database of Systematic Reviews (January 2014 to January 2019) was searched for 'cancer' AND 'pain' in the title, abstract or keywords. A MEDLINE search was also made. RESULTS A strong opioid remains the drug of choice for treating moderate or severe pain. Bisphosphonates and radiotherapy are also effective for cancer-related bone pain. Optimal management requires a tailored approach, support for self-management and review of treatment outcomes. There is likely a role for non-pharmacological approaches. Paracetamol should not be used in patients taking a strong opioid to treat pain. Cannabis-based medicines are not recommended. Weak opioids, ketamine and lidocaine are indicated in specific situations only. CONCLUSION Interventions commonly recommended by guidelines are not always supported by a robust evidence base. Research is required to evaluate the efficacy of non-steroidal anti-inflammatory drugs, anti-convulsants, anti-depressants, corticosteroids, some invasive anaesthetic techniques, complementary therapies and transcutaneous electrical nerve stimulation.

Abstract
CONTEXT Opioids are prescribed to manage moderate-to-severe pain and can be used with older adults; however, they may lead to several adverse effects, including cognitive impairment. OBJECTIVES To identify, appraise, and synthesize evidence on the impact of opioids on cognition in older adults with cancer/chronic noncancer pain, and screening tools/neuropsychological assessments used to detect opioid-induced cognitive impairment. METHODS A systematic literature review following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (international prospective register of systematic reviews registration: CRD42018092943). MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Library, and Web of Science were searched up to December 2018. Randomized controlled trials, quasi-experimental studies, and observational studies of adults aged 65 years and older with cancer/chronic noncancer pain taking opioids were included. A narrative synthesis was conducted. RESULTS From 4036 records, 10 met inclusion criteria. Five studies used one screening tool, and five studies used a range of neuropsychological assessments; assessing 14 cognitive domains. Most studies demonstrated no effect of opioid use on cognitive domains, whereas four studies showed mixed effects. In particular, attention, language, orientation, psychomotor function, and verbal working/delayed episodic memory were worsened. Changes to cognitive function were predominantly observed in studies with higher mean doses of opioids (120-190.7mg oral morphine equivalent daily dose). CONCLUSION Both improvements and impairments to cognition were observed in studies with higher mean opioid doses. In clinical practice, a brief screening tool assessing attention, language, orientation, psychomotor function, and verbal working/delayed episodic memory may be beneficial to detect worsening cognition in older adults with chronic pain using opioids.

Abstract
ObjectivesThere is increased interest in cannabinoids for cancer pain management and legislative changes are in progress in many countries. This study aims to determine the beneficial and adverse effects of cannabis/cannabinoids compared with placebo/other active agents for the treatment of cancer-related pain in adults.MethodsSystematic review and meta-analysis to identify randomised controlled trials of cannabinoids compared with placebo/other active agents for the treatment of cancer-related pain in adults to determine the effect on pain intensity (primary outcome) and adverse effects, including dropouts. Searches included Embase, MEDLINE, PsycINFO, Web of Science, ClinicalTrials.gov, Cochrane and grey literature. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed.ResultsWe identified 2805 unique records, of which six randomised controlled trials were included in this systematic review (n=1460 participants). Five studies were included in the meta-analysis (1442 participants). All had a low risk of bias. There was no difference between cannabinoids and placebo for the difference in the change in average Numeric Rating Scale pain scores (mean difference −0.21 (−0.48 to 0.07, p=0.14)); this remained when only phase III studies were meta-analysed: mean difference −0.02 (−0.21 to 0.16, p=0.80). Cannabinoids had a higher risk of adverse events when compared with placebo, especially somnolence (OR 2.69 (1.54 to 4.71), p<0.001) and dizziness (OR 1.58 (0.99 to 2.51), p=0.05). No treatment-related deaths were reported. Dropouts and mortality rates were high.ConclusionsStudies with a low risk of bias showed that for adults with advanced cancer, the addition of cannabinoids to opioids did not reduce cancer pain.Trial registration numberCRD42018107662.

Abstract
BACKGROUND Recognising dying is a key clinical skill for doctors, yet there is little training. AIM To assess the effectiveness of an online training resource designed to enhance medical students' ability to recognise dying. DESIGN Online multicentre double-blind randomised controlled trial (NCT03360812). The training resource for the intervention group was developed from a group of expert palliative care doctors' weightings of various signs/symptoms to recognise dying. The control group received no training. SETTING/PARTICIPANTS Participants were senior UK medical students. They reviewed 92 patient summaries and provided a probability of death within 72 hours (0% certain survival - 100% certain death) pre, post, and 2 weeks after the training. Primary outcome: (1) Mean Absolute Difference (MAD) score between participants' and the experts' scores, immediately post intervention. Secondary outcomes: (2) weight attributed to each factor, (3) learning effect and (4) level of expertise (Cochran-Weiss-Shanteau (CWS)). RESULTS Out of 168 participants, 135 completed the trial (80%); 66 received the intervention (49%). After using the training resource, the intervention group had better agreement with the experts in their survival estimates (δMAD = -3.43, 95% CI -0.11 to -0.34, p = <0.001) and weighting of clinical factors. There was no learning effect of the MAD scores at the 2-week time point (δMAD = 1.50, 95% CI -0.87 to 3.86, p = 0.21). At the 2-week time point, the intervention group was statistically more expert in their decision-making versus controls (intervention CWS = 146.04 (SD 140.21), control CWS = 110.75 (SD 104.05); p = 0.01). CONCLUSION The online training resource proved effective in altering the decision-making of medical students to agree more with expert decision-making.

Abstract
PURPOSE Opioids reduce cancer-related pain but an association with shorter survival is variably reported. AIM To investigate the relationship between pain, analgesics, cancer and survival within the European Palliative Care Cancer Symptom (EPCCS) study to help inform clinical decision making. METHODS Secondary analysis of the international prospective, longitudinal EPCCS study which included 1739 adults with advanced, incurable cancer receiving palliative care. In this secondary analysis, for all participants with date of death or last follow up, a multilevel Weibull survival analysis examined whether pain, analgesics, and other relevant variables are associated with time to death. RESULTS Date of death or last follow-up was available for 1404 patients (mean age 65.7 [SD:12.3];men 50%). Secondary analysis of this group showed the mean survival from baseline was 46.5 (SD:1.5) weeks (95% CI:43.6-49.3). Pain was reported by 76%; 60% were taking opioids, 51% non-opioid analgesics and 24% co-analgesics. Opioid-use was associated with decreased survival in the multivariable model (HR = 1.59 (95% CI:1.38-1.84), p < 0.001). An exploratory subgroup analysis of those with C-reactive protein (CRP) measures (n = 219) indicated higher CRP was associated with poorer survival (p = 0.001). In this model, the strength of relationship between survival and opioid-use weakened (p = 0.029). CONCLUSION Opioid-use and survival were associated; this relationship weakened in a small sensitivity-testing subgroup analysis adjusting for CRP. Thus, the observed relationship between survival and opioid-use may partly be due to tumour-related inflammation. Larger studies, measuring disease activity, are needed to confirm this finding to more accurately judge the benefits and risks of opioids in advanced progressive disease.

Abstract
Palliative care is the holistic care of patients with advanced, progressive incurable illness. Palliative care is well recognized as an essential component of medical student curricula. However, teaching is variable within medical schools. Using current literature, these tips aim to highlight key points necessary to facilitate the development and delivery of palliative care teaching to medical students. The key practice points include: clinical exposure to patients with palliative care needs and those that are dying, being compulsory (and integrated) across the course, summative and formative assessments to encourage learning, support from within the university for curricular time and development, visits to a hospice/inpatient palliative care facility, emphasis on clinically based learning later in the course, teaching by specialists in palliative care as well as specialists in other areas including Family Doctors/General Practitioners, innovative teaching methods and inter-professional learning to develop teaching.

Abstract
Introduction and objective The diagnosis of primary headaches is based on the International Classification of Headache Disorders (ICHD-3). Cluster headache (CH), a debilitating primary headache, is often misdiagnosed as migraine. In the absence of biological markers, a new visual screening tool with images depicting pain could aid the correct diagnosis of CH. The objective of the study is to test the tool on healthy participants and participants with CH and migraine. Methods In phase 1, 6 images portraying people with pain were tested on 150 healthy participants. The healthy participants were asked to rate the images as mild, moderate, severe or excruciating pain. In phase 2, the images were further tested on 116 participants with headache (16 participants with CH, 100 participants with migraine). The participants were recruited prospectively from a tertiary headache center between February and May 2017. The participants were asked to choose which image best illustrated their headache attacks. Results Phase 1 results showed that the images represent a range of headache pain severities from mild to excruciating as rated by healthy participants. They rated two images as excruciating, one image as severe, one image as moderate/severe, one image as moderate and one image as mild. Phase 2 results showed that two-thirds of participants with CH (69%) and half of the participants with migraine (52%) chose an image described as excruciating by the healthy participants. Conclusion We developed a screening tool with six drawings depicting headache pain severities from mild to excruciating as rated by the healthy participants. Although the images did not differentiate between CH and migraine, the study indicated the potential of using visual aids to assess headache severity.

Abstract
CONTEXT Patients with cancer often experience distressing symptoms such as anxiety or dyspnea, which can be managed with benzodiazepines; however, concerns regarding the impact of these drugs on survival may dissuade prescribing and compliance. OBJECTIVES We aimed to identify and appraise studies examining benzodiazepine use and survival in adults with cancer, to investigate the relationship and context of use. METHODS Systematic review of the international literature prepared according to preferred reporting items for systematic reviews. Comprehensive searches of the MEDLINE, Embase, PsycINFO, Cochrane Library, and AMED databases using medical subject heading and free-text search combinations with no date or language restrictions were undertook. Handsearching of references was conducted. Risk of bias of the included studies was assessed using Grading of Recommendations Assessment, Development, and Evaluation criteria. RESULTS Two thousand two hundred fifty-seven unique records were identified, with 18 meeting inclusion criteria, representing 4117 patients. All studies were very low quality. No study found an increase in mortality in association with benzodiazepine use, whereas two demonstrated an increase. CONCLUSION Existing evidence shows no association between benzodiazepine use in patients with cancer and decreased survival. None of the studies evaluated the association between benzodiazepine use and survival in earlier stages of cancer, and the quality of studies retrieved signifies a need for further robust studies to draw more definitive conclusions. Further investigation in patients with cancer using well-designed, high-quality research with survival as a primary outcome should be conducted.

Delirium management by palliative medicine specialists: a survey from the association for palliative medicine of Great Britain and Ireland. BMJ Support Palliat Care 2019; 12:73-80. [PMID: 30837278 DOI: 10.1136/bmjspcare-2018-001586] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 11/21/2018] [Accepted: 02/11/2019] [Indexed: 11/04/2022]
Abstract
OBJECTIVES Delirium is common in palliative care settings. Management includes detection, treatment of cause(s), non-pharmacological interventions and family support; strategies which are supported with varying levels of evidence. Emerging evidence suggests that antipsychotic use should be minimised in managing mild to moderate severity delirium, but the integration of this evidence into clinical practice is unknown. METHODS A 21-question online anonymous survey was emailed to Association for Palliative Medicine members in current clinical practice (n=859), asking about delirium assessment, management and research priorities. RESULTS Response rate was 39%: 70% of respondents were palliative medicine consultants. Delirium guidelines were used by some: 42% used local guidelines but 38% used none. On inpatient admission, 59% never use a delirium screening tool. Respondents would use non-pharmacological interventions to manage delirium, either alone (39%) or with an antipsychotic (58%). Most respondents (91%) would prescribe an antipsychotic and 6% a benzodiazepine, for distressing hallucinations unresponsive to non-pharmacological measures. Inpatient (57%) and community teams (60%) do not formally support family carers. Research priorities were delirium prevention, management and prediction of reversibility. CONCLUSION This survey of UK and Irish Palliative Medicine specialists shows that delirium screening at inpatient admission is suboptimal. Most specialists continue to use antipsychotics in combination with non-pharmacological interventions to manage delirium. More support for family carers should be routinely provided by clinical teams. Further rigorously designed clinical trials are urgently needed in view of management variability, emerging evidence and perceived priorities for research.

Abstract
BACKGROUND: Performance status, a predictor of cancer survival, and ability to maintain independent living deteriorate in advanced disease. Understanding predictors of performance status trajectory could help identify those at risk of functional deterioration, target support for independent living and reduce service costs. The relationship between symptoms, analgesics and performance status is poorly delineated. AIM: The aim of this study is to determine whether demographics, analgesics, disease characteristics, quality-of-life domains and C-reactive protein predict the trajectory of Karnofsky Performance Status (KPS) in patients with advanced cancer. DESIGN: The study design is the secondary data analysis of the international prospective, longitudinal European Palliative Care Cancer Symptom study (ClinicalTrials.gov: NCT01362816). A multivariable regression model was built for KPS area under the curve per day (AUC). SETTING AND PARTICIPANTS: This included adults with advanced, incurable cancer receiving palliative care, without severe cognitive impairment and who were not imminently dying (n = 1739). RESULTS: The mean daily KPS AUC (n = 1052) was 41.1 (standard deviation = 14.1). Opioids (p < 0.001), co-analgesics (p = 0.023), poorer physical functioning (p < 0.001) and appetite loss (p = 0.009) at baseline were explanatory factors for lower KPS AUC. A subgroup analysis of participants with C-reactive protein data (n = 240) showed that only C-reactive protein (p = 0.040) and physical function (p < 0.001) were associated with lower KPS AUC. CONCLUSION: This study is novel in determining explanatory factors for subsequent functional trajectories in an international dataset and identifying systemic inflammation as a candidate therapeutic target to improve functional performance. The effect of interventions targeting physical function, appetite and inflammation, such as those used for cachexia management, on maintaining functional status in patients with advanced cancer needs to be investigated.

Abstract
OBJECTIVE Cluster headache (CH) is the most severe primary headache condition. Its pathophysiology is multifaceted and incompletely understood. This review brings together the latest neuroimaging and neuropeptide evidence on the pathophysiology of CH. METHODS A review of the literature was conducted by searching PubMed and Web of Science. The search was conducted using the following keywords: imaging studies, voxel-based morphometry, diffusion-tensor imaging, diffusion magnetic resonance imaging, tractography, connectivity, cerebral networks, neuromodulation, central modulation, deep brain stimulation, orexin-A, orexin-B, tract-based spatial statistics, single-photon emission computer tomography studies, positron-emission tomography, functional magnetic resonance imaging, magnetic resonance spectroscopy, trigeminovascular system, neuropeptides, calcitonin gene-related peptide, neurokinin A, substance P, nitric oxide synthase, pituitary adenylate cyclase-activating peptide, vasoactive intestinal peptide, neuropeptide Y, acetylcholine, noradrenaline, and ATP. "Cluster headache" was combined with each keyword for more relevant results. All irrelevant and duplicated records were excluded. Search dates were from October 1976 to May 2018. RESULTS Neuroimaging studies support the role of the hypothalamus in CH, as well as other brain areas involved in the pain matrix. Activation of the trigeminovascular system and the release of neuropeptides play an important role in CH pathophysiology. Among neuropeptides, calcitonin gene-related peptide, vasoactive intestinal peptide, and pituitary adenylate cyclase-activating peptide have been reported to be reliable biomarkers for CH attacks, though not specific for CH. Several other neuropeptides are involved in trigeminovascular activation, but the current evidence does not qualify them as reliable biomarkers in CH. CONCLUSION CH has a complex pathophysiology and the pain mechanism is not completely understood. Recent neuroimaging studies have provided insight into the functional and structural network bases of CH pathophysiology. Although there has been important progress in neuropeptide studies, a specific biomarker for CH is yet to be found.

Abstract
BACKGROUND: Red blood cell transfusions are commonly used in palliative care to treat anaemia or symptoms caused by anaemia. In patients with advanced disease, there is little evidence of benefit to guide treatment decisions in the face of increased risk of harms. AIM: To determine national transfusion practice in hospices and compare this against National Institute for Health and Care Excellence and British Society of Haematology guidelines to develop recommendations to improve practice. DESIGN AND SETTING: Prospective data collection on red blood cell transfusion practice in UK adult hospices over a 3-month census period. RESULTS: A total of 121/210 (58%) hospices participated. A total of 465 transfusion episodes occurred in 83 hospices. Patients had a mean age of 71 years, and 96% had cancer. Mean pre-transfusion haemoglobin was 75 g/L (standard deviation = 11.15). Anaemia of chronic disease was the largest cause of anaemia (176; 38%); potentially amenable to alternative treatments. Haematinics were not checked in 70% of patients. Alternative treatments such as B12, folate and iron were rarely used. Despite transfusion-associated circulatory overload risk, 85% of patients were not weighed, and 84% had two or more units transfused. Only 83 (18%) patients had an improvement maintained at 30 days; 142 (31%) had <14 day improvement, and 50 (11%) had no improvement. A total of 150 patients (32%) were dead at 30 days. CONCLUSION: More rigorous investigation of anaemia, increased use of alternative therapies and more restrictive approach to red cell transfusions are recommended. Clinicians should discuss the limited benefit versus potentially higher risks with patients in hospice services to inform treatment decisions.

Abstract
INTRODUCTION Patients with cluster headache (CH), the most common trigeminal autonomic cephalalgia, often face delayed diagnosis, misdiagnosis and mismanagement. OBJECTIVES To identify, appraise and synthesise clinical studies on the delays in diagnosis and misdiagnosis of CH in order to determine its causes and help the management of this condition. METHODS The systematic review was prepared, conducted and reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis. It was registered with International Prospective Register of Systematic Reviews. A systematic search of different electronic databases (Medline, EMBASE, PsycINFO, PubMed, CINAHL, BNI, HMIC, AMED, HBE and Cochrane Library) was carried out in May 2017. Reference lists of relevant articles were hand searched. RESULTS The search identified 201 unique studies. Fifteen studies met the inclusion criteria of which 13 case series studies and two survey studies. Nine studies assessed the delays in diagnosis and misdiagnosis of CH, five studies the delays in diagnosis and one study the misdiagnosis of CH. The studies included 4661 patients. Delays in diagnosis, misdiagnosis and mismanagement have been reported in many European countries, Japan and in the USA with well-developed health services. The patients with CH often visited many different clinicians, surgeons and dentists and received multiple diagnosis prior to being correctly diagnosed. CONCLUSION This systematic review shows that the delays in the diagnosis of CH are a widespread problem, the time to diagnosis still vary from country to country and both patients and physicians are responsible for the delays in diagnosis.

Abstract
BACKGROUND Radiation therapy (RT) results in pain relief for about 6 of 10 patients with cancer induced bone pain (CIBP) caused by bone metastases. The high number of non-responders, the long median time from RT to pain response and the risk of adverse effects, makes it important to determine predictors of treatment response. Clinical features such as cancer type, performance status and pain intensity, and biomarkers for osteoclast activity are proposed as predictors of response to RT. However, results are inconsistent and there is a need for better predictors of RT response. A similar argument can be stated for the development of cachexia; there are currently no predictors that can identify patients who will develop cachexia later in the cancer disease trajectory. Experimental and preclinical studies show that pain, depression and cachexia are related to inflammation. However, it is not known if inflammatory biomarkers can predict CIBP, depression or development of cachexia. METHODS This multicenter, multinational longitudinal observational study will include 600 adult patients receiving RT for CIBP. Demographic data, clinical variables, osteoclast and inflammatory biomarkers will be assessed before start of RT, and 3, 8, 16, 24 and 52 weeks after last course of RT. The primary aim of the study is to identify potential predictors for pain relief from RT. Secondary aims are to explore potential predictors for development of cachexia, the longitudinal relationship between pain intensity and depression, and if inflammatory biomarkers are associated with changes in pain intensity, cachexia and depression during one-year follow up. DISCUSSION The immediate clinical implication of the PRAIS study is to identify potential predictive factors for a RT response on CIBP, and thereby reduce non-efficacious RT. Patient benefits are fewer hospital visits, reduced risk of adverse effects and more individualized pain treatment. The long-term clinical implication of the PRAIS study is to improve the knowledge about inflammation in relation to CIBP, cachexia and depression and potentially identify associations and mechanisms that can be targeted for treatment. TRIAL REGISTRATION ClinicalTrials.gov NCT02107664 , date of registration April 8, 2014 (retrospectively registered).

Abstract
BACKGROUND Morphine can cause central nervous system side effects which impair driving skills. The legal blood morphine concentration limit for driving is 20 µg/L in France/Poland/Netherlands and 80 µg/L in England/Wales. There is no guidance as to the morphine dose leading to this concentration. AIM The in silico (computed) relationship of oral morphine dose and plasma concentration was modelled to provide dose estimates for a morphine plasma concentration above 20 and 80 µg/L in different patient groups. DESIGN A dose-concentration model for different genders, ages and oral morphine formulations, validated against clinical pharmacokinetic data, was generated using Simcyp®, a population-based pharmacokinetic simulator. SETTING/PARTICIPANTS Healthy Northern European population parameters were used with age, gender and renal function being varied in the different simulation groups. In total, 36,000 simulated human subjects (100 per modelled group of different ages and gender) received repeated simulated morphine dosing with modified-release or immediate-release formulations. RESULTS Older age, women, modified-release formulation and worse renal function were associated with higher plasma concentrations. Across all groups, morphine doses below 20 mg/day were unlikely to result in a morphine plasma concentration above 20 µg/L; this was 80 mg/day with the 80 µg/L limit. CONCLUSION This novel study provides predictions of the in silico (computed) dose-concentration relationship for international application. Individualised morphine prescribing decisions by clinicians must be informed by clinical judgement considering the individual patient's level of impairment and insight irrespective of the blood morphine concentration as people who have impaired driving will be breaking the law. Taking into account expected morphine concentrations enables improved individualised decision making.

Abstract
OBJECTIVES Numerous in vitro studies have evaluated the influence of opioids on many biological and immunological processes. The concentrations that have been used in these studies span a large range and often do not reflect levels that are present in the relevant patient groups. This article reviews the literature concerning the concentrations of opioids that are detected in patients so that the concentrations of opioids that are used for in vitro studies can better reflect those that are present clinically. This will enable scientists and clinicians to more effectively model and interpret potentially relevant clinical effects from in vitro studies. METHODS Data on the concentrations of six commonly used opioids from clinical studies in adults were collected by searching PubMed (Medline). RESULTS A total of 42 relevant studies were included in the review. Concentrations of the opioids from previous clinical studies were mostly between 1 and 10 ng/mL for buprenorphine, 1 and 10 ng/mL for fentanyl, 50 and 500 ng/mL for methadone, 25 and 250 ng/mL for morphine, 10 and 100 ng/mL for oxycodone, and 100 and 1,000 ng/mL for Tramadol and were dependent on the patient group and indication under investigation. CONCLUSIONS Concentrations of opioids used in vitro should include those that are present in the relevant clinical setting if the effects of opioids detected in vitro are to be of potential relevance to the clinical setting. Therefore, it is essential that these concentrations in the relevant clinical context(s) are known.
