Continuous Electrocardiographic Monitoring for 24 Hours Before Death in Patients with Terminal Cancer.

BACKGROUND: Purposeless physiological monitoring at the end-of-life is not recommended. However, studies on how families feel regarding the death of patients with terminal cancer without continuous electrocardiographic monitoring (CEM) are lacking. OBJECTIVES: To explore the impact on the quality of care and the feelings and psychological distress experienced by families when CEM is not used during the 24 hours preceding a patient's death. METHODS: In this multicenter cross-sectional, self-report questionnaires were distributed to 1087 bereaved families at Japanese specialized palliative care units in 2018. RESULTS: Out of 671 responses, 394 valid responses were analyzed. Families of nonmonitored patients (NM-group) accounted for 79.2%, while those with bedside electrocardiogram monitoring (MB-group) and remote nurse station monitoring (MC-group) comprised 11.9% and 8.9%, respectively. In the NM-group, 85.5% expressed satisfaction without CEM, which was more than 10% lower than other groups. While 14% in the NM-group desired patient monitoring, families who received adequate explanations about CEM had lower proportions compared to the MB-group (P = .021). Univariate analyses showed no significant differences in evaluations of the quality of care and families' psychological distress (mean scores of Overall Care Satisfaction, Care Evaluation Scale, Good Death Inventory, Brief Grief Questionnaires) across all groups. CONCLUSION: While the majority of NM-group were satisfied with their patient's care without CEM, the proportion of dissatisfied families was higher than in other groups. Although not using CEM is not a major hindrance to end-of-life care for patients with terminal cancer, providing sufficient explanations may be important for satisfactory care.

Are Prognostic Scores Better Than Clinician Judgment? A Prospective Study Using Three Models.

CONTEXT: Several prognostic models such as the Palliative Performance Scale (PPS), Palliative Prognostic Index (PPI), Palliative Prognostic Score (PaP) have been developed to complement clinician's prediction of survival (CPS). However, few studies with large scales have been conducted to show which prognostic tool had better performance than CPS in patients with weeks of survival. OBJECTIVES: We aimed to compare the prognostic performance of the PPS, PPI, PaP, and CPS in inpatients admitted to palliative care units (PCUs). METHODS: This study was part of a multi-center prospective observational study involving patients admitted to PCUs in Japan. We computed their prognostic performance using the area under the receiver operating characteristics curve (AUROC) and calibration plots for seven, 14-, 30- and 60-day survival. RESULTS: We included 1896 patients with a median overall survival of 19 days. The AUROC was 73% to 84% for 60-day and 30-day survival, 75% to 84% for 14-day survival, and 80% to 87% for seven-day survival. The calibration plot demonstrated satisfactory agreement between the observational and predictive probability for the four indices in all timeframes. Therefore, all four prognostic indices showed good performance. CPS and PaP consistently had significantly better performance than the PPS and PPI from one-week to two-month timeframes. CONCLUSION: The PPS, PPI, PaP, and CPS had relatively good performance in patients admitted to PCUs with weeks of survival. CPS and PaP had significantly better performance than the PPS and PPI. CPS may be sufficient for experienced clinicians while PPS may help to improve prognostic confidence for inexperienced clinicians.

Does Urinary Catheterization Affect the Quality of Death in Patients with Advanced Cancer? A Secondary Analysis of a Multicenter Prospective Cohort Study.

Background: Patients with life-limiting illnesses frequently experience urinary difficulties, and urinary catheterization is one of the interventions for managing them. However, evidence supporting the effects of urinary catheters on the quality of death (QoD) is lacking in this population. Objectives: To investigate whether urinary catheterization affects QoD in patients with advanced cancer in palliative care units. Design: A secondary analysis of a multicenter, prospective cohort study. Setting/Subjects: The study enrolled consecutive patients with advanced cancer admitted to palliative care units in Japan between January and December 2017. Those who were not catheterized on admission and who died while in a palliative care unit were analyzed. Measurements: QoD was evaluated at death using the Good Death Scale (GDS). Results: Of 885 patients, 297 (33.6%) were catheterized during their palliative care unit stay. Females and patients with a long palliative care unit stay were more likely to be catheterized. In inverse probability-weighted propensity score analysis, patients with urinary catheterization during their palliative care unit stay had higher total GDS scores than those without catheterization (coefficient 0.410, 95% confidence interval 0.068-0.752). In subgroup analyses stratified by sex, age, and length of palliative care unit stay, urinary catheterization was associated with higher total GDS scores in patients younger than 65 years of age and those who died after a palliative care unit stay of 21 days or fewer. Conclusions: This study suggested that urinary catheterization during a palliative care unit stay may have a positive impact on overall QoD in patients with advanced cancer. This study was registered in the UMIN Clinical Trials Registry (UMIN000025457).

C-Reactive Protein and Its Relationship with Pain in Patients with Advanced Cancer Cachexia: Secondary Cross-Sectional Analysis of a Multicenter Prospective Cohort Study.

Background: Limited information is available on the relationship between C-reactive protein (CRP) levels and pain in advanced cancer. Objectives: To investigate the relationship between serum levels of CRP and subtypes of pain. Design: A secondary cross-sectional analysis of a prospective cohort study. Setting/Subjects: Patients with advanced cancer admitted to 23 palliative care units in Japan. Measurements: Patients rated the severity of pain on the numerical rating scale (NRS) and physicians evaluated pain on the integrated palliative care outcome scale (IPOS). Physicians assessed neuropathic pain and breakthrough pain based on their presence or absence. Patients were divided into four groups according to CRP levels. Comparisons were performed using the Kruskal-Wallis test or chi-squared test. To evaluate the relationship between CRP and subtypes of pain, adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in logistic models were calculated. Results: We divided 1513 patients into four groups: low CRP (n = 234), moderate CRP (n = 513), high CRP (n = 352), and very high CRP (n = 414). Spearman's correlation coefficient between CRP and pain NRS and that between CRP and pain IPOS were 0.15 (p < 0.001) and 0.16 (p < 0.001), respectively. In the models of pain NRS and pain IPOS, significantly higher adjusted ORs than in the low CRP group were observed in the very high CRP group (1.81 [95% CI 1.14-2.88], p = 0.01; 1.74 [95% CI 1.18-2.57], p = 0.005, respectively). Relationships were not observed between CRP, neuropathic pain, and breakthrough pain. Conclusions: The results indicated direct relationships between CRP, pain NRS, and pain IPOS.

Relationship Between the Activities of Gloss-Selective Neurons in the Macaque Inferior Temporal Cortex and the Gloss Discrimination Behavior of the Monkey.

In the macaque monkey, neurons that selectively respond to specific gloss are present in a restricted region of the central part of the inferior temporal (IT) cortex. Although the population activity of these neurons is known to represent the perceptual gloss space, the involvement of their activity in gloss perception has not been directly tested. In the present study, we examined the causal relationship between the activities of gloss-selective neurons and gloss perception by applying electrical microstimulation or injection of small amounts of muscimol (GABAA agonist) to manipulate neural activities while monkeys performed a gloss discrimination task. We found that microstimulation within or in the vicinity of the region where gloss-selective neurons were recorded induced bias toward higher gloss judgment. With muscimol injection, gloss discrimination performance was degraded in one monkey after the first injection into the region where gloss-selective neurons were recorded. These results suggest that gloss discrimination behavior is mediated by the activities of a gloss-selective network that includes the gloss-selective region in the central IT cortex examined here.

Efficacy of Proportional Sedation and Deep Sedation Defined by Sedation Protocols: A Multicenter, Prospective, Observational Comparative Study.

PURPOSE: To investigate the efficacy of two types of palliative sedation: proportional and deep sedation, defined by sedation protocols. METHODS: From a multicenter prospective observational study, we analyzed the data of those patients who received the continuous infusion of midazolam according to the sedation protocol. The primary endpoint was goal achievement at 4 hours: in proportional sedation, symptom relief (Integrated Palliative care Outcome Scale: IPOS ≤ 1) and absence of agitation (modified Richmond Agitation-Sedation Scale: RASS ≤ 0); in deep sedation, the achievement of deep sedation (RASS ≤ -4). Secondary endpoints included deep sedation as a result of proportional sedation, communication capacity (Communication Capacity Scale item 4 ≤ 2), IPOS and RASS scores, and adverse events. RESULTS: A total of 81 patients from 14 palliative care units were analyzed: proportional sedation (n = 64) and deep sedation (n = 17). At 4 hours, the goal was achieved in 77% (n = 49; 95% confidence interval: 66-87) with proportional sedation; and 88% (n = 15; 71-100) with deep sedation. Deep sedation was necessary in 45% of those who received proportional sedation. Communication capacity was maintained in 34% with proportional sedation and 10% with deep sedation. IPOS decreased from 3.5 to 0.9 with proportional sedation, and 3.5 to 0.4 with deep sedation; RASS decreased from +0.3 to -2.6, and +0.4 to -4.2, respectively. Fatal events related to the treatment occurred in 2% (n = 1) with proportional and none with deep sedation. CONCLUSION: Proportional sedation achieved satisfactory symptom relief while maintaining some patients' consciousness, and deep sedation achieved good symptom relief while the majority of patients lost consciousness.

Comparison of the prevalence and associated factors of hyperactive delirium in advanced cancer patients between inpatient palliative care and palliative home care.

BACKGROUND: Hyperactive delirium is known to increase family distress and the burden on health care providers. We compared the prevalence and associated factors of agitated delirium in advanced cancer patients between inpatient palliative care and palliative home care on admission and at 3 days before death. METHODS: This was a post hoc exploratory analysis of two multicenter, prospective cohort studies of advanced cancer patients, which were performed at 23 palliative care units (PCUs) between Jan and Dec 2017, and on 45 palliative home care services between July and Dec 2017. RESULTS: In total, 2998 patients were enrolled and 2829 were analyzed in this study: 1883 patients in PCUs and 947 patients in palliative home care. The prevalence of agitated delirium between PCUs and palliative home care was 5.2% (95% CI: 4.2% - 6.3%) vs. 1.4% (0.7% - 2.3%) on admission (p < 0.001) and 7.6% (6.4% - 8.9%) vs. 5.4% (4.0% - 7.0%) 3 days before death (p < 0.001). However, multivariate logistic regression analysis revealed that the place of care was not significantly associated with the prevalence of agitated delirium at 3 days before death after adjusting for prognostic factors, physical risk factors, and symptoms. CONCLUSIONS: There was no significant difference in the prevalence of agitated delirium at 3 days before death between inpatient palliative care and palliative home care after adjusting for the patient background, prognostic factors, symptoms, and treatment.

The Principles of Revised Clinical Guidelines about Palliative Sedation Therapy of the Japanese Society for Palliative Medicine.

Background: When the suffering of a terminally ill patient is intolerable and refractory, sedatives are sometimes used for symptom relief. Objective: To describe the main principles of revised Japanese clinical guidelines about palliative sedation therapy. Design: Consensus methods using the Delphi technique were used. Results: The main principles of the guidelines that were newly defined or developed are as follows: (1) palliative sedation was defined as "administration of sedatives for the purpose of alleviating refractory suffering" (excluding the aim of reducing patient consciousness); (2) palliative sedation was classified according to the method of administration of sedatives: respite sedation versus continuous sedation (including (continuous) proportional sedation and continuous deep sedation); (3) a description of state-of-the-art recommended treatments for difficult symptoms such as delirium, dyspnea, and pain before the symptom was determined as refractory was included; (4) the principle of proportionality was newly defined from an ethical point of view; and (5) families' consent was regarded as being desirable (mandatory in the previous version). Conclusions: We described the main principles of revised Japanese clinical guidelines about palliative sedation therapy. Further consensus building is necessary.

A combination of routine laboratory findings and vital signs can predict survival of advanced cancer patients without physician evaluation: a fractional polynomial model.

INTRODUCTION: There have been no reports about predicting survival of patients with advanced cancer constructed entirely with objective variables. We aimed to develop a prognostic model based on laboratory findings and vital signs using a fractional polynomial (FP) model. METHODS: A multicentre prospective cohort study was conducted at 58 specialist palliative care services in Japan from September 2012 to April 2014. Eligible patients were older than 20 years and had advanced cancer. We developed models for predicting 7-day, 14-day, 30-day, 56-day and 90-day survival by using the FP modelling method. RESULTS: Data from 1039 patients were analysed to develop each prognostic model (Objective Prognostic Index for advanced cancer [OPI-AC]). All models included the heart rate, urea and albumin, while some models included the respiratory rate, creatinine, C-reactive protein, lymphocyte count, neutrophil count, total bilirubin, lactate dehydrogenase and platelet/lymphocyte ratio. The area under the curve was 0.77, 0.81, 0.90, 0.90 and 0.92 for the 7-day, 14-day, 30-day, 56-day and 90-day model, respectively. The accuracy of the OPI-AC predicting 30-day, 56-day and 90-day survival was significantly higher than that of the Palliative Prognostic Score or the Prognosis in Palliative Care Study model, which are based on a combination of symptoms and physician estimation. CONCLUSION: We developed highly accurate prognostic indexes for predicting the survival of patients with advanced cancer from objective variables alone, which may be useful for end-of-life management. The FP modelling method could be promising for developing other prognostic models in future research.

Low Transthyretin Levels Predict Poor Prognosis in Cancer Patients in Palliative Care Settings.

OBJECTIVES: Although transthyretin (TTR) is a nutritional indicator and is influenced by systemic inflammation, it may be a good prognostic indicator for cancer patients in palliative care settings. This study investigates the correlation between low TTR levels and survival among cancer patients in palliative care settings. METHODS: This was a sub-analysis of a prospective, multicenter cohort study. Patients who had advanced-stage cancer and who were newly referred to palliative care services were eligible to participate; however, those receiving anti-tumor therapy were excluded. Survival analyses were performed to clarify predictors of poor prognosis. RESULTS: A total of 144 patients were enrolled (45.1% female; median age, 72 years). Cox regression analysis revealed that low TTR levels (<10.9 mg/l) (hazard ratio 1.74, P = 0.025), poor muscle power (1.71, P = 0.045), and fatigue (1.89, P = 0.024) were predictors of poor prognosis. Median survival in patients with low TTR levels (<10.9 mg/l) was 26 days, which was significantly shorter than those with high TTR levels (≥10.9 mg/l) (50 days; P < 0.001). CONCLUSION: Low TTR levels may be indicators for poor prognosis among cancer patients in palliative care settings.

"What I Did for My Loved One Is More Important than Whether We Talked About Death": A Nationwide Survey of Bereaved Family Members.

BACKGROUND: Actions in preparation for death and talks about death between advanced cancer patients and their families are considered essential to achieve a good death. However, little is known about the prevalence of such actions compared with talks and their association with bereaved families' psychological morbidity. OBJECTIVE: To clarify the prevalence of bereaved families having acted in preparation for death and talked about death with their loved one, and to explore their associations with bereaved families' depression and complicated grief (CG). DESIGN: A nationwide survey. Setting/Subject: A total of 999 bereaved families of cancer patients admitted to 133 inpatient hospices in Japan. MEASUREMENTS: The prevalence of families' actions in preparation for and talks about death, Patient Health Questionnaire (PHQ)-9, and Brief Grief Questionnaire (BGQ). RESULTS: Among 678 bereaved families (response rate = 68%), 513 (76%) acted in preparation for death, and 315 (46%) talked about death with their loved one. Those who acted and talked were significantly less likely to suffer depression (PHQ-9 ≥ 10) than those who neither acted nor talked (odds ratio [OR], 0.405; 95% confidence interval [CI], 0.195-0.845; adjusted p = 0.016). Families who acted were significantly less likely to suffer complicated grief (CG; BGQ ≥8), whether they talked (OR, 0.394; 95% CI, 0.185-0.84; adjusted p = 0.016) or not (OR, 0.421; 95% CI, 0.191-0.925; adjusted p = 0.031). CONCLUSIONS: Most families acted in preparation for death, and those who acted were less likely to suffer depression and CG. Clinicians may minimize families' later psychological morbidity by helping patients and families act in preparation for death.

Development and validation of a set of six adaptable prognosis prediction (SAP) models based on time-series real-world big data analysis for patients with cancer receiving chemotherapy: A multicenter case crossover study.

BACKGROUND: We aimed to develop an adaptable prognosis prediction model that could be applied at any time point during the treatment course for patients with cancer receiving chemotherapy, by applying time-series real-world big data. METHODS: Between April 2004 and September 2014, 4,997 patients with cancer who had received systemic chemotherapy were registered in a prospective cohort database at the Kyoto University Hospital. Of these, 2,693 patients with a death record were eligible for inclusion and divided into training (n = 1,341) and test (n = 1,352) cohorts. In total, 3,471,521 laboratory data at 115,738 time points, representing 40 laboratory items [e.g., white blood cell counts and albumin (Alb) levels] that were monitored for 1 year before the death event were applied for constructing prognosis prediction models. All possible prediction models comprising three different items from 40 laboratory items (40C3 = 9,880) were generated in the training cohort, and the model selection was performed in the test cohort. The fitness of the selected models was externally validated in the validation cohort from three independent settings. RESULTS: A prognosis prediction model utilizing Alb, lactate dehydrogenase, and neutrophils was selected based on a strong ability to predict death events within 1-6 months and a set of six prediction models corresponding to 1,2, 3, 4, 5, and 6 months was developed. The area under the curve (AUC) ranged from 0.852 for the 1 month model to 0.713 for the 6 month model. External validation supported the performance of these models. CONCLUSION: By applying time-series real-world big data, we successfully developed a set of six adaptable prognosis prediction models for patients with cancer receiving chemotherapy.

Talking About Death With Terminally-Ill Cancer Patients: What Contributes to the Regret of Bereaved Family Members?

CONTEXT: Talking about death is an important issue for terminally-ill cancer patients and their families. Little is known about how often and which bereaved families regret not having talked about death with their deceased loved one. OBJECTIVES: To explore the prevalence of a regret of not having talked about death with a deceased loved one among bereaved family members of adult cancer patients, and to systematically explore factors contributing to their regret. METHODS: We conducted a nationwide survey of 999 bereaved families of cancer patients admitted to 133 inpatient hospices in Japan and surveyed families' regret on talking about death. Exploratory analyses identified the underlying structures of process, option, and outcome subscales of factors contributing to regret. RESULTS: Among 678 bereaved families (response rate 68%), 224 (33%) regretted not having talked about death sufficiently, whereas 40 (5.9%) conversely regretted having talked about death. Three process factors ("prognostic disclosure to patient" [ß = 0.082, P = 0.039], "upsetting of patient and family" [ß = 0.127, P = 0.001], and "family's sense of uncertainty about when to act based on terminal awareness" [ß = 0.141, P = 0.000]) and an outcome factor ("having achieved a good death" [ß = -0.152, P = 0.000]) contributed to the regret of talking insufficiently. CONCLUSION: A third of bereaved families of adult cancer patients regretted not having talked about death sufficiently. Clinicians may minimize this regret by facilitating a shared understanding of the disease and prognosis, advising families explicitly when to talk based on terminal awareness, providing continuous emotional support, and validating their decision on talking about death.

Predictors of Delirium in Corticosteroid-Treated Patients with Advanced Cancer: An Exploratory, Multicenter, Prospective, Observational Study.

BACKGROUND: Corticosteroids are often used to treat fatigue and anorexia, but occasionally produce delirium. Information on the predictors of delirium in corticosteroid-treated cancer patients remains limited. OBJECTIVE: To identify potential factors predicting the development of delirium in corticosteroid-treated cancer patients. DESIGN: An exploratory, multicenter, prospective, observational study. SETTING/SUBJECTS: Inclusion criteria for this study were patients who had metastatic or locally advanced cancer and a fatigue or anorexia intensity score of 4 or more on a 0-10 Numerical Rating Scale. MEASUREMENT: Univariate and multivariable analyses were performed to identify the predictors of delirium diagnosed by the Confusion Assessment Method (CAM) within three days of initiation of corticosteroids. RESULTS: Among 207 patients administered corticosteroids, 35 (17%; 95% confidence interval [CI] 12%-23%) developed at least one episode of delirium diagnosed by the CAM. Factors predictive of the development of delirium were as follows: Palliative Performance Scale ≤20, Eastern Cooperative Oncology Group Performance Status (ECOG PS) = 4, the Support Team Assessment Schedule (STAS) score of drowsiness >1, concurrent opioid use, parenteral hydration volume ≤500 mL, and the absence of lung metastasis. A multivariable analysis identified the independent factors predicting responses as ECOG PS = 4 (odds ratio [OR] 4.0; 95% CI 1.7-9.3), STAS score of drowsiness >1 (OR 3.4; 95% CI 1.4-8.2), and concurrent opioid use (OR 3.7; 95% CI 1.0-13). CONCLUSION: Delirium in corticosteroid-treated advanced cancer patients may be predicted by PS, drowsiness, and concurrent opioid use. Larger prospective studies are needed to confirm these results.

C-reactive protein, symptoms and activity of daily living in patients with advanced cancer receiving palliative care.

BACKGROUND: The association between C-reactive protein (CRP) level, symptoms, and activities of daily living (ADL) in advanced cancer patients is unclear. METHODS: Secondary data analysis of a multicenter prospective cohort study consisted of 2426 advanced cancer patients referred to palliative care settings was conducted to examine the cross-sectional relationships between CRP level, symptoms, and ADL disabilities. Laboratory data, symptoms, ADL, and manual muscle testing (MMT) results were obtained at baseline. Participants were divided into four groups: low (CRP < 1 mg/dl), moderate (1 = < CRP <5 mg/dl), high (5 = < CRP < 10 mg/dl), and very high CRP (10 mg/dl = < CRP). The proportions of eight symptoms, five ADL disabilities, and three categories of MMT according to the CRP groups were tested by chi-square tests. Multiple-adjusted odd ratios (ORs) were calculated by using ordinal logistic regression after adjustment for age, gender, site of primary cancer, metastatic disease, performance status, chemotherapy, and setting of care. RESULTS: A total of 1702 patients were analysed. Positive rates of symptoms and ADL disabilities increased with increasing CRP level. In the very high-CRP group, rates of positivity for anorexia, fatigue, and weight loss were 89.8%, 81.0%, and 79.2%, respectively, and over 70% of patients received assistance for bathing, dressing, going to the toilet, and transfer. The grade of MMT also deteriorated with increasing CRP level. Adjusted ORs for the accumulated symptoms significantly increased with increasing CRP level in the moderate-CRP, high-CRP, and very high-CRP groups [1.6 (95% confidence interval 1.2-2.0), P < 0.001; 2.5 (1.9-3.2), P < 0.001; 3.5 (2.7-4.6), P < 0.001, respectively]. Adjusted ORs for the accumulated ADL disabilities significantly increased in the very high-CRP groups [2.1 (1.5-2.9), P < 0.001]. CONCLUSIONS: Associations between CRP level, symptoms, and ADL were observed in advanced cancer patients receiving palliative care.

A prospective, multicenter cohort study to validate a simple performance status-based survival prediction system for oncologists.

BACKGROUND: Survival prediction systems such as the Palliative Prognostic Index (PPI), which includes the Palliative Performance Scale (PPS), are used to estimate survival for terminally ill patients. Oncologists are, however, less familiar with the PPS in comparison with the Eastern Cooperative Oncology Group (ECOG) performance status (PS). This study was designed to validate a simple survival prediction system for oncologists, the Performance Status-Based Palliative Prognostic Index (PS-PPI), which is a modified form of the PPI based on the ECOG PS. METHODS: This multicenter, prospective cohort study enrolled all consecutive patients who were referred to 58 palliative care services in Japan. The primary responsible physicians rated the variables required to calculate the PS-PPI and the PPI. Patient survival in these risk groups was compared, and the sensitivity and specificity of the PS-PPI and the PPI were evaluated. Patients were subclassified as patients receiving care from in-hospital palliative care teams, palliative care units, or home-based palliative care services. Subsets of patients receiving chemotherapy were also analyzed. RESULTS: This study included 2346 patients. Survival predictions based on the PPI and the PS-PPI differed significantly among the 3 risk groups (P < .001). The PS-PPI was more sensitive, whereas the PPI was more specific. All areas under the receiver operating characteristic curves of both indices were >0.78 for predicting survival at all times, from 3 weeks to 180 days. CONCLUSIONS: In predicting the prognosis of patients with advanced cancer, the PS-PPI was as accurate as the PPI. The PS-PPI was useful for short- and long-term survival prediction and for the prediction of survival for patients undergoing chemotherapy. Cancer 2017;123:1442-1452. © 2016 American Cancer Society.

Predictors of responses to corticosteroids for anorexia in advanced cancer patients: a multicenter prospective observational study.

PURPOSE: Although corticosteroids are widely used to relieve anorexia, information regarding the factors predicting responses to corticosteroids remains limited. The purpose of the study is to identify potential factors predicting responses to corticosteroids for anorexia in advanced cancer patients. METHODS: Inclusion criteria for this multicenter prospective observational study were patients who had metastatic or locally advanced cancer and had an anorexia intensity score of 4 or more on a 0-10 Numerical Rating Scale (NRS). Univariate and multivariate analyses were conducted to identify the factors predicting ≥2-point reduction in NRS on day 3. RESULTS: Among 180 patients who received corticosteroids, 99 (55 %; 95 % confidence interval [CI], 47-62 %) had a response with ≥2-point reduction. Factors that significantly predicted responses were Palliative Performance Scale (PPS) > 40 and absence of drowsiness. In addition, factors that tended to be associated with ≥2-point reduction in NRS included PS 0-3, absence of diabetes mellitus, absence of peripheral edema, presence of lung metastasis, absence of peritoneal metastasis, baseline anorexia NRS of >6, presence of pain, and presence of constipation. A multivariate analysis showed that the independent factors predicting responses were PPS of >40 (odds ratio = 2.7 [95 % CI = 1.4-5.2]), absence of drowsiness (2.6 [1.3-5.0]), and baseline NRS of >6 (2.4 [1.1-4.8]). CONCLUSIONS: Treatment responses to corticosteroids for anorexia may be predicted by PPS, drowsiness, and baseline symptom intensity. Larger prospective studies are needed to confirm these results.

Adding items that assess changes in activities of daily living does not improve the predictive accuracy of the Palliative Prognostic Index.

BACKGROUND: Changes in activities of daily living in cancer patients may predict their survival. The Palliative Prognostic Index is a useful tool to evaluate cancer patients, and adding an item about activities of daily living changes might improve its predictive value. AIM: To clarify whether adding an item about activities of daily living changes improves the accuracy of Palliative Prognostic Index. DESIGN: Multicenter prospective cohort study. SETTING: A total of 58 palliative care services in Japan. PARTICIPANTS: Patients aged >20 years diagnosed with locally extensive or metastatic cancer (including hematological neoplasms) who had been admitted to palliative care units, were receiving care by hospital-based palliative care teams, or were receiving home-based palliative care. Palliative care physicians recorded clinical variables at the first assessment and followed up patients 6 months later. RESULTS: A total of 2425 subjects were recruited and 2343 of these had analyzable data. The C-statistic of the original Palliative Prognostic Index was 0.801, and those of modified Palliative Prognostic Indices ranged from 0.793 to 0.805 at 3 weeks. For 6-week survival predictions, the C-statistic of the original Palliative Prognostic Index was 0.802, and those of modified Palliative Prognostic Indices ranged from 0.791 to 0.799. The weighted kappa of the original Palliative Prognostic Index was 0.510, and those of modified Palliative Prognostic Indices ranged from 0.484 to 0.508. CONCLUSION: Adding items about activities of daily living changes to the Palliative Prognostic Index did not improve prognostic value in advanced cancer patients.

Prospective Validation of the Objective Prognostic Score for Advanced Cancer Patients in Diverse Palliative Settings.

CONTEXT: Prognostication is an essential part of palliative care to aid decision making and negotiate goals of care. The Objective Prognostic Score (OPS) is an easy-to-use prognosticating tool to predict survival among far-advanced cancer patients in palliative care units (PCUs) in Korea. OBJECTIVES: This study aimed to prospectively validate the OPS for advanced cancer patients in the palliative care teams (PCTs), PCUs, and home-based palliative care (HPC) in Japan. METHODS: This was a substudy of a multicenter prospective cohort study that was conducted to validate and compare prognostic tools among advanced cancer patients in Japan. Participants' survival was calculated according to OPS 3 as a cutoff for predicting survival of less than three weeks. Overall accuracy and area under the receiver operator characteristic curves of OPS 3 were calculated for PCT, PCU, and HPC, respectively. RESULTS: A total of 1146 cases (PCTs 441, PCUs 519, and HPCs 186 cases) were included in final analyses. The overall accuracy of OPS 3 for predicting three-week survival ranged from 0.70 to 0.78 across diverse palliative care settings. The c-statistics ranged from 0.742 to 0.808 across three settings. Participants in the PCT showed the highest overall accuracy and c-statistics for OPS. CONCLUSION: The OPS can be used for prognostication among advanced cancer patients in PCT, PCU, and HPC settings.

Effects of generalized pooling on binocular disparity selectivity of neurons in the early visual cortex.

The key problem of stereoscopic vision is traditionally defined as accurately finding the positional shifts of corresponding object features between left and right images. Here, we demonstrate that the problem must be considered in a four-dimensional parameter space; with respect not only to shifts in space (X, Y), but also spatial frequency (SF) and orientation (OR). The proposed model sums outputs of binocular energy units linearly over the multi-dimensional V1 parameter space (X, Y, SF, OR). Theoretical analyses and physiological experiments show that many binocular neurons achieve sharp binocular tuning properties by pooling the output of multiple neurons with relatively broad tuning. Pooling in the space domain sharpens disparity-selective responses in the SF domain so that the responses to combinations of unmatched left-right SFs are attenuated. Conversely, pooling in the SF domain sharpens disparity selectivity in the space domain, reducing the possibility of false matches. Analogous effects are observed for the OR domain in that the spatial pooling sharpens the binocular tuning in the OR domain. Such neurons become selective to relative OR disparity. Therefore, pooling allows the visual system to refine binocular information into a form more desirable for stereopsis.This article is part of the themed issue 'Vision in our three-dimensional world'.
