Background: The Surprise Question ('Would I be surprised if this patient died within 12 months?') identifies patients in the last year of life. It is unclear if 'surprised' means the same for each clinician, and whether their responses are internally consistent. Aim: To determine the consistency with which the Surprise Question is used. Design: A cross-sectional online study of participants located in Belgium, Germany, Italy, The Netherlands, Switzerland and UK. Participants completed 20 hypothetical patient summaries ('vignettes'). Primary outcome measure: continuous estimate of probability of death within 12 months (0% [certain survival]–100% [certain death]). A threshold (probability estimate above which Surprise Question responses were consistently 'no') and an inconsistency range (range of probability estimates where respondents vacillated between responses) were calculated. Univariable and multivariable linear regression explored differences in consistency. Trial registration: NCT03697213. Setting/participants: Registered General Practitioners (GPs). Of the 307 GPs who started the study, 250 completed 15 or more vignettes. Results: Participants had a consistency threshold of 49.8% (SD 22.7) and inconsistency range of 17% (SD 22.4). Italy had a significantly higher threshold than other countries (p = 0.002). There was also a difference in threshold levels depending on age of clinician, for every yearly increase, participants had a higher threshold. There was no difference in inconsistency between countries (p = 0.53). Conclusions: There is variation between clinicians regarding the use of the Surprise Question. Over half of GPs were not internally consistent in their responses to the Surprise Question. Future research with standardised terms and real patients is warranted. [ABSTRACT FROM AUTHOR]

Objective: Recognizing delirium phenomenology (DP) aids the early diagnosis of this syndrome and improves quality of life in patients with advanced cancer. The aim of this study was to identify the neurobehavioral and cognitive patterns of delirium-related symptoms in persons with advanced cancer. Methods: We conducted an observational comparative prospective study on delirium in patients with advanced cancer in different palliative care settings, assessing the presentation/evolution of DP with the Memorial delirium assessment scale (MDAS). Results: Two hundred twenty-seven patients were enrolled on hospital/hospice admission. Of these, 57 were admitted with delirium, 170 without delirium, and 31 developed delirium during hospitalization. Of the 88 patients admitted with delirium or who developed it during hospitalization, only 32 underwent two consecutive MDAS evaluations (at diagnosis and after one week). Delirium resolved in 22 patients (first average MDAS score 10.08 vs. second 3.6 [p < 0.001]). Disorientation, short-term memory, and memory span were altered in all patients with unresolved delirium. The same features were altered in 18 (80%), 17 (80%), and 16 (70%) of the patients with resolved delirium, respectively, and in 58 (35%), 114 (67%), and 38 (23%) of no-delirium patients, respectively. Conclusion: Cognitive-related symptoms appear to be the most prevalent and earliest signs of DP in patients with advanced cancer. [ABSTRACT FROM AUTHOR]

Background: Delirium in advanced cancer inpatient ranges between 13% and 85%. Reasons for this variability on the reported data could be related to the setting where they are admitted. Methods: This is an observational, comparative, prospective study on delirium diagnosis and delirium course of advanced cancer inpatients in two different palliative care settings. Hospice (C1) versus palliative care supportive team (C2). Differences between delirium precipitants, delirium treatment, and delirium survival were observed. Results: From 582 consecutive admissions, 494 from C1 and 88 from C2, finally 227 patients met inclusion criteria, were entered in the study. Total population delirium rate at admission, if we add both centers, was 57 patients (25%), 46 (26%) from C1 and 11 (22%) from C2; no statistically significant differences between delirium rate at admission between the two centers were found (χ2). When delirium course between delirious patients admitted in C1 and C2 was analyzed, a significantly higher rate of delirium reversibility was found in C2 [11/14 (78%)] versus [9/65 (14%)] in C1 (χ2p ≤ 0.001). Conclusion: The frequency of delirium at admission and during the hospitalization in advanced cancer patients does not seem to be related to the setting, what seems to be related is the delirium course.

Purpose: The in vivo evaluation of three modified polyethylene glycol (PEG)-anilinoquinazoline derivatives labeled with (124)I, (18)F, and (11)C as potential positron emission tomography (PET) bioprobes for visualizing epidermal growth factor receptor (EGFR) in cancer using small animal PET.Procedures: Xenograft mice with the human glioblastoma cell lines U138MG (lacking EGFR expression) and U87MG.wtEGFR (transfected with an overexpressing human wild-type EGFR gene) were used. Static and dynamic PET imaging was conducted for all three PEGylated compounds. Tumor necrosis, microvessel density, and EGFR levels were evaluated by histopathology and enzyme-linked immunosorbent assay.Results: Nineteen animal models were generated (two U138MG, three U87MG, 14 with both U138MG and U87MG bilateral masses). In static images, a slight increase in tracer uptake was observed in tumors, but in general, there was no retention of tracer uptake over time and no difference in uptake between U138MG and U87MG masses. In addition, no significant uptake was demonstrated in dynamic scans of the (18)F-PEG tracer. No necrosis was present except in four animals. MVD was 9.6 and 48 microvessels/×400 field in the U138GM and U87GM masses, respectively (p = 0.00008). Similarly, the microvessel grades were generally higher in the U87GM group (p = 0.002). Total EGFR amount was higher in U87MG than U138MG masses (p = 0.001), but the ratio of activated (pY1068) to total EGFR did not differ (p = 0.95).Conclusions: PEGylated tracers labeled with (11)C, (124)I, and (18)F showed no significant difference in uptake between U138MG and U87MG glioblastoma xenograft mice. The tracer binding with EGFR could be influenced by activation of the tyrosine kinase portion of the receptor which was similar in U138MG and U87MG. Despite these results, these tracers should be investigated in animal models with mutant EGFR genes to determine whether aberrant receptor function plays a role in tumor uptake.

To determine the clinical significance of Helicobacter pylori seropositivity and seronegativity in healthy blood donors, we carried out a serological evaluation of Helicobacter pylori status and endoscopy in a healthy blood donors population. In all, 1010 donors were screened for Helicobacter pylori by IgG ELISA and assessed for pepsinogen I and gastrin levels by RIA; 298 IgG seropositive and 61 seronegative subjects underwent endoscopy with biopsies. Of 359, 165 were also tested for CagA by western blotting. Of the 298 IgG seropositives, 274 were shown to be infected on biopsy testing. Endoscopy revealed 70 peptic ulcers, 41 cases of erosive duodenitis, and two gastric cancers. In all 105 seropositive donors were tested for CagA and 69 were CagA positive [34/58 gastritis (58.6%), 24/35 duodenal ulcer (68.6%) and 11/12 gastric ulcer (91.6%)]. Histologically active/chronic gastritis was associated with CagA: 88.4% vs 50% (CagA seropositive vs seronegative). Of the 61 IgG seronegatives, 59 were negative on biopsy testing. At endoscopy three had duodenitis. Of the 60/61 IgG seronegatives tested for CagA, one had a moderate reaction. Duodenal ulcer donors showed higher pepsinogen I levels than donors without duodenal ulcers (97.7 microg/ml vs 80.9 microg/ml respectively). Screening for Helicobacter pylori and anti-CagA seropositivity and pepsinogen I can identify individuals likely to have gastroduodenal pathology even in the absence of symptoms.

Context Palliative medicine (PM), still in the development phase, is a new, growing specialty aimed at caring for both oncology and non-oncology patients. There is still confusion about the training offered in the various European PM certification programs. Objectives To provide a detailed, comparative update and analysis of the PM certification process in Europe, including the different training approaches and their main features. Methods Experts from each country completed an online survey addressing historical background, program name, training requirements, length of time in training, characteristic and content, official certifying institution, effectiveness of accreditation, and 2013 workforce capacity. We prepared a comparative analysis of the data provided. Results In 2014, 18 of 53 European countries had official programs on specialization in PM (POSPM): Czech Republic, Denmark, Finland, France, Georgia, Germany, Hungary, Ireland, Israel, Italy, Latvia, Malta, Norway, Poland, Portugal, Romania, Slovakia, and the U.K. Ten of these programs were begun in the last five years. The PM is recognized as a “specialty,” “subspecialty,” or “special area of competence,” with no substantial differences between the last two designations. The certification contains the term “palliative medicine” in most countries. Clinical training varies, with one to two years being the most frequent duration. There is a clear trend toward establishing the POSPM as a mandatory condition for obtaining a clinical PM position in countries' respective health systems. Conclusion PM is growing as a specialization field in Europe. Processes leading to certification are generally long and require substantial clinical training. The POSPM education plans are heterogeneous. The European Association for Palliative Care should commit to establishing common learning standards, leading to additional European-based recognition of expertise in PM. [ABSTRACT FROM AUTHOR]

Background: Current understanding of genetic factors associated with pain severity, and improvement of pain with opioids in advanced cancer patients (AC) is inadequate for delivery of personalized pain therapy (PPT). Therefore, the aim of this study was to determine the genetic factors associated with pain severity, daily opioid dose, and pain response in AC patients receiving supportive care.Methods: In this prospective study, AC patients were eligible if they had cancer pain ≥4/10 on Edmonton Symptom Assessment Scale (ESAS) - Pain Item and needed opioid rotation for pain control by specialist at the outpatient supportive care center. Association of genetic factors with pain phenotype was assessed using logistic regression models and SKATO (Gene-block) analysis.Results: About 174/178 (98%) patient samples were analyzed. After adjustment for demographic and clinical variables, pain severity was negatively associated with intron variant alleles in OPRM1 rs9322446, P = 0.02; rs2270459, P = 0.038; rs62052210, P = 0.038. Opioid daily dose was positively associated NFKBIA rs2233419, P = 0.008; rs2233417, P = 0.007; rs3138054, P = 0.008; rs1050851, P = 0.015; ORPM1 rs9479759, P = 0.046; rs2003185, P = 0.047; rs636433, P = 0.044; COMT (rs9306234, P = 0.014; rs165728, P = 0.014; rs2020917, P = 0.036; rs165728, P = 0.034); ARRB2 (rs1045280, P = 0.045); and pain response to opioids was negatively associated OPRM1 rs1319339, P = 0.024; rs34427887, P = 0.048; and COMT rs4646316, P = 0.03; rs35478083, P = 0.028, respectively. SKATO analysis showed association between pain severity and CXCL8 (P = 0.0056), and STAT6 (P = 0.0297) genes respectively, and pain response with IL-6 (P = 0.00499).Conclusions: This study identified that SNPs of OPRM1, COMT, NFKBIA, CXCL8, IL-6, STAT6, and ARRB2 genes were associated with pain severity, opioid daily dose, and pain response in AC receiving supportive care. Additional studies are needed to validate our findings for PPT. [ABSTRACT FROM AUTHOR]
