RESUMO

BACKGROUND: Despite advances in medical technologies and intervention occurrences, acute kidney injury (AKI) incidence continues to rise. Early interventions after sepsis are essential to prevent AKI and its long-term consequences. Acute kidney injury is the leading cause of organ failure in sepsis; therefore, more research is needed on its long-term consequences and progression to kidney injury. OBJECTIVES: The aim of this study was to review the state of the science on long-term renal outcomes after sepsis-induced AKI and long-term renal consequences. METHODS: We identified research articles from PubMed and CINAHL databases using relevant key words for sepsis-induced AKI within 5 years delimited to full-text articles in English. RESULTS: Among 1280 abstracts identified, we ultimately analyzed 12 full-text articles, identifying four common themes in the literature: (1) AKI determination criteria, (2) severity/prognosis-related factors, (3) time frame for long-term outcome measures, and (4) chronic kidney disease (CKD) and renal related exclusions. Researchers primarily used KDIGO (Kidney Disease: Improving Global Outcomes) guidelines to define AKI. All of these studies excluded patients with CKD. The range of time for long-term renal outcomes was 28 days to 3 years, with the majority being 1 year. Renal outcomes ranged from recovery to renal replacement therapy to death. CONCLUSIONS: To better understand the long-term renal outcomes after sepsis-induced AKI, more consistent measures are needed across all studies regarding the time frame and specific renal outcomes. Because all of these articles excluded patients with CKD, a gap exists on long-term renal outcome in acute on CKD.

RESUMO

Introduction: Multikinase inhibitors have clinical activity in radioactive iodine refractory (RAIR) differentiated thyroid cancers (DTCs) but are not curative; optimal management and salvage therapies remain unclear. This study assessed clinical effects of pazopanib therapy in RAIR-DTC patients with progressive disease, examining in parallel biomarker that might forecast/precede therapeutic response. Methods: Assessment of responses and toxicities and of any association between thyroglobulin (Tg) changes cycle 1 and RECIST (response evaluation criteria in solid tumors) response to pazopanib therapy were prospectively undertaken in Tg antibody negative RAIR-DTC patients. RECIST progressive metastatic disease <6 months preceding enrollment was required. With a sample size of 68 (assuming 23 attaining partial response [PR]), there would be 90% chance of detecting a difference of >30% when the proportion of patients attaining PR whose Tg values decrease by >50% is >50% cycle 1 (one-sided α = 0.10, two sample test of proportions). Mean corpuscular volume (MCV) change or mutational status or pretreatment were also explored as early correlates of eventual RECIST response. Results: From 2009 to 2011, 60 individuals were treated and evaluated; (one additional patient withdrew; another was found ineligible before therapy initiation); 91.7% had previous systemic therapy beyond RAI. Adverse events included one death (thromboembolic) deemed possibly pazopanib associated. Twenty-two confirmed RECIST PRs resulted (36.7%, confidence interval; CI [24.6-50.1]); mean administered 4-week cycles was 10. Among 44 fully accessible patients, the Tg nadir was greater among the 20 attaining PR (median: -86.8%; interquartile range [IQR]: -90.7% to -70.9%) compared with the 28 who did not (median: -69.0%; IQR: -78.1% to -27.7%, Wilcoxon rank-sum test: p = 0.002). However, the difference in the proportion of PRs among those whose Tg fell ≥50% after cycle 1 versus those that did not were not significantly correlated (-23.5% [CI: -55.3 to 8.3]; Fisher's exact test p-value = 0.27). RECIST response was also not correlated with/predicted by early MCV change, receipt of prior therapy, or tumor mutational status. Conclusions: This trial prospectively confirmed pazopanib to have clinical activity and manageable toxicities in patients with progressive RAIR-DTC. Response to pazopanib, however, was not robustly forecast by early associated changes in Tg or MCV, by prior therapy, or by tumor mutational status. ClinicalTrials.gov NCT00625846.

RESUMO

BACKGROUND: Women with gynecologic cancer may be at increased risk for adverse events (AEs) due to peritoneal disease burden and prior treatment (surgery, chemotherapy, and pelvic radiotherapy). This study compared the toxicity profiles of patients with and without gynecologic cancer enrolled in phase 1 trials. METHODS: This was a retrospective analysis of the National Cancer Institute phase 1 database for all trials enrolling 1 or more patients with gynecologic cancer over 2 decades (1995-2015). Clinical parameters collected included demographics, cancer history, trial information, AEs, and responses. AEs (according to the Common Terminology Criteria for Adverse Events) were documented for each patient during treatment, and they were counted once and analyzed on the basis of the highest grade and drug attribution. Multiple regression models were used to compare AEs at the baseline and during treatment. RESULTS: A total of 4269 patients enrolled in 150 trials were divided into 3 groups: 1) women with gynecologic cancer (n = 685), 2) women with nongynecologic cancer (n = 1698), and 3) men with cancer (n = 1886). The median age was 58 years. The mean number of total AEs reported during treatment was highest for women with gynecologic cancer (17.1 vs 14.7 vs 13.5; P < .001), even though they were similar at the baseline (7.0 vs 7.4 vs 7.0; P = .09). The mean number of drug-related AEs was also highest for women with gynecologic cancer (8.3 vs 6.9 vs 6.2; P < .001). Grade 3 to 5 AEs were similar (2.3 vs 2.3 vs 2.1); however, grade 2 AEs were more frequent in women with gynecologic cancer (4.6 vs 3.9 vs 3.5). Treatment discontinuations due to AEs were similar (9% vs 9% vs 10%). CONCLUSIONS: Women with gynecologic cancer experienced more frequent low-grade AEs during treatment, and this warrants attention to support their symptom burden. Study dose management should be considered for recurrent grade 2 AEs, particularly during continuous therapy.

RESUMO

The U.S. art museum sector is grappling with diversity. While previous work has investigated the demographic diversity of museum staffs and visitors, the diversity of artists in their collections has remained unreported. We conduct the first large-scale study of artist diversity in museums. By scraping the public online catalogs of 18 major U.S. museums, deploying a sample of 10,000 artist records comprising over 9,000 unique artists to crowdsourcing, and analyzing 45,000 responses, we infer artist genders, ethnicities, geographic origins, and birth decades. Our results are threefold. First, we provide estimates of gender and ethnic diversity at each museum, and overall, we find that 85% of artists are white and 87% are men. Second, we identify museums that are outliers, having significantly higher or lower representation of certain demographic groups than the rest of the pool. Third, we find that the relationship between museum collection mission and artist diversity is weak, suggesting that a museum wishing to increase diversity might do so without changing its emphases on specific time periods and regions. Our methodology can be used to broadly and efficiently assess diversity in other fields.

RESUMO

Mixtures of group-based Markov models of evolution correspond to joins of toric varieties. In this paper, we establish a large number of cases for which these phylogenetic join varieties realize their expected dimension, meaning that they are nondefective. Nondefectiveness is not only interesting from a geometric point-of-view, but has been used to establish combinatorial identifiability for several classes of phylogenetic mixture models. Our focus is on group-based models where the equivalence classes of identified parameters are orbits of a subgroup of the automorphism group of the abelian group defining the model. In particular, we show that for these group-based models, the variety corresponding to the mixture of r trees with n leaves is nondefective when [Formula: see text]. We also give improved bounds for claw trees and give computational evidence that 2-tree and 3-tree mixtures are nondefective for small n.

RESUMO

Phase 1 trials of molecularly targeted agents (MTA) often do not use toxicity data beyond the first cycle of treatment to determine a recommended phase 2 dose (RP2D). We investigated the potential utility of longitudinal relative dose intensity (RDI) that may be a better new way of determining a more accurate RP2D as a lower dose that is presumably more tolerable over the long term without compromising efficacy. All consecutive patients who were initially treated using a single MTA at the conventional RP2D or at one level lower dose (OLLD) of that RP2D in 9 phase 1 trials sponsored by the National Cancer Institute were included. The associations between longitudinal RDI, time to first progression, and response rate were analyzed. The RDI of the conventional RP2D group were maintained a rate of ≥70% throughout 10 cycles, and were higher than those of the OLLD group, although in both groups the RDI gradually decreased with additional treatment cycles. The RP2D group was similar to the OLLD group with respect to time to first progression and response rate. In both groups, however, the decreasing RDI over time was significantly associated with shorter time to first disease progression; therefore, the longitudinal RDI, which takes into account lower grade toxicity occurrences, may be useful in determining a more desirable dose to use in phase 2 and 3 studies.

RESUMO

PURPOSE: Breast cancer (BC) is the most commonly diagnosed cancer and the second leading cause of cancer-related death among women. Given the availability of approved therapies and abundance of phase II and III clinical trials, historically few BC patients have been referred for consideration of participation on a phase I trial. We were interested in determining whether clinical benefit rates differed in patients with BC from other patients enrolled in phase I trials. METHODS: We performed a retrospective analysis of all Cancer Therapy Evaluation Program (CTEP) sponsored phase I trials from 1993 to 2012. We report an analysis of demographic variables, rates of response to treatment, grade 4 toxicities, and treatment-related deaths. RESULTS: De-identified data from 8087 patients were analyzed, with 1,376 having a diagnosis of BC. The median time from initial cancer diagnosis to enrollment in a CTEP-sponsored phase I clinical trial was 614 days for all patients. Breast cancer patients were enrolled on average 790 days after initial diagnosis, while non-BC patients had a median enrollment time of 582 days (p < 0.001). Breast cancer patients had more clinical responses than non-BC patients (18.3% vs. 4.3%, respectively). Along with the higher rate of response, BC patients remained on phase I trials longer than non-BC patients with a median of 70 days while the latter were on trial for a median of 57 days. The overall rate of death related to the treatment drugs was 0.47%. CONCLUSIONS: Our data confirm our hypothesis that when compared to a general population of patients with cancer enrolled on phase I clinical trials, BC patients tend to derive clinical benefit from these therapies with similar toxicity profile. This evidence further supports enrollment of BC patients on phase I trials.

RESUMO

Intrahepatic cholestasis of pregnancy (ICP) affects 1/140 UK pregnancies; with pruritus, hepatic impairment and elevated serum bile acids. Severe disease is complicated by spontaneous preterm delivery and stillbirth. Previous studies have reported mutations in hepatocellular transporters (ABCB4, ABCB11). High throughput sequencing in 147 patients was performed in the transporters ABCB4, ABCB11, ATP8B1, ABCC2 and tight junction protein 2 (TJP2). Twenty-six potentially damaging variants were identified with the following predicted protein changes: Twelve ABCB4 mutations - Arg47Gln, Met113Val, Glu161Gly, Thr175Ala, Glu528Glyfs*6, Arg590Gln, Ala601Ser, Glu884Ter, Gly722Ala, Tyr775Met (x2), Trp854Ter. Four potential ABCB11 mutations - Glu297Gly (x3) and a donor splice site mutation (intron 19). Five potential ATP8B1 mutations - Asn45Thr (x3), and two others, Glu114Gln and Lys203Glu. Two ABCC2 mutations - Glu1352Ala and a duplication (exons 24 and 25). Three potential mutations were identified in TJP2; Thr62Met (x2) and Thr626Ser. No patient harboured more than one mutation. All were heterozygous. An additional 545 cases were screened for the potential recurrent mutations of ATP8B1 (Asn45Thr) and TJP2 (Thr62Met) identifying three further occurrences of Asn45Thr. This study has expanded known mutations in ABCB4 and ABCB11 and identified roles in ICP for mutations in ATP8B1 and ABCC2. Possible novel mutations in TJP2 were also discovered.

RESUMO

INTRODUCTION: Pheochromocytomas and paragangliomas (Pheo/PGL) are rare, vascular, sometimes malignant endocrine tumors. Case reports indicate the activity of vascular endothelium growth factor receptor-targeted kinase inhibitors in these cancers. OBJECTIVES: To assess the antitumor activity and tolerability of pazopanib in progressive malignant Pheo/PGL. PATIENTS AND METHODS: This multicenter Phase II trial (MC107C) enrolled individuals ≥18 years old with disease progression ≤ 6 months prior to registration, Eastern Cooperative Oncology Group PS 0-2, and measurable disease (response evaluation criteria in solid tumors 1.0). Pazopanib was administered in 28-day cycles, with the regimen ultimately being as follows: cycle 1: 400 mg daily on days 1-14, cycle 2: 800 mg daily on days 1-14, and then cycle 2 + : 800 mg daily on all days. RESULTS: The study was halted due to poor accrual. Seven patients were enrolled (05/2011-11/2014). One patient withdrew consent prior to treatment, leaving six evaluable patients. Treatment was discontinued, due to the following reasons: disease progression (4); withdrawal (1); and grade 4 (Takotsubo) cardiomyopathy (1). The median number of cycles administered was 4 (range: 2-29, total: 49). Four patients had >1 dose reduction due to the following reasons: fatigue (1), abnormal liver tests (2), hypertension and (Takotsubo) cardiomyopathy (1), and headaches (1). Common severe (Common Terminology Criteria for Adverse Events v3.0 grades 3-5) toxicities were as follows: hypertension (3/6), (Takotsubo) cardiomyopathy (2/6), diarrhea (1/6), fatigue (1/6), headache (1/6), and hematuria (1/6). One confirmed partial response was observed in PGL (17%, duration 2.4 years); median progression-free survival and overall survival were 6.5 and 14.8 months, respectively. CONCLUSION: Pazopanib has activity in Pheo/PGL requiring more study; optimal alpha- and beta-blockade are imperative pre-therapy in patients with secretory tumors, as risk of hypertension and cardiomyopathy are potentially life threatening.

RESUMO

BACKGROUND: Growth in hospice utilisation has been accompanied by an increase in the proportion of hospice patients who die in an inpatient hospice setting rather than at home. OBJECTIVE: To determine whether this increase in inpatient utilisation is consistent with patient preferences. DESIGN: Retrospective cohort study. SETTING: Seven hospices in the Coalition of Hospices Organised to Investigate Comparative Effectiveness (CHOICE) network. PATIENTS: 70 488 patients admitted between 1 July 2008 and 31 May 2012. MEASUREMENTS: We measured changes in patients' stated preferences at the time of admission regarding site of death, including weights to adjust for non-response bias. We also assessed patients' actual site of death and concordance with patients' preferences. RESULTS: More patients died receiving inpatient care in 2012 as compared to 2008 (1920 (32.7%), 2537 (18.5%); OR 1.21; 95% CI 1.19 to 1.22; p<0.001). However, patients also expressed an increasing preference for dying in inpatient settings (weighted preferences 27.5% in 2012 vs 7.9% in 2008; p<0.001). The overall proportion of patients who died in the setting of their choice (weighted preferences) increased from 74% in 2008 to 78% in 2012 (p<0.001). LIMITATIONS: This study included only seven hospices, and results may not be representative of the larger hospice population. CONCLUSIONS: Although more patients are dying while receiving inpatient care, these changes in site of death seem to reflect changing patient preferences. The net effect is that patients in this sample were more likely to die in the setting of their choice in 2012 than they were in 2008.

RESUMO

BACKGROUND: In phase 1 trials, an important entry criterion is life expectancy predicted to be more than 90 days, which is generally difficult to predict. The Royal Marsden Hospital (RMH) prognostic score that is determined by lactate dehydrogenase level, albumin level, and number of metastatic sites of disease was developed to help project patient outcomes. There have been no systematic analyses to evaluate the utility of the RMH prognostic score for esophagogastric cancer patients. METHODS: All nonpediatric phase 1 oncology trials sponsored by the National Cancer Institute Cancer Therapy Evaluation Program that began between 2001 and 2013 were considered in this review. RESULTS: Of 4722 patients with solid tumors, 115 patients were eligible for our analysis; 54 (47 %) with cancer of the esophagus, 14 (12 %) with cancer of the esopagogastric junction, and 47 (41 %) with stomach cancer. Eighty-six patients (75 %) had a good RMH prognostic score (0 or 1) and 29 patients (25 %) had a poor RMH prognostic score (2 or 3). Disease control rates were significantly different between patients with good and poor RMH prognostic scores (49 % vs 17 %; two-sided Fisher's exact test P = 0.004). The median treatment duration and overall survival for good and poor RMH prognostic score patients were significantly different (median treatment duration 2.1 months vs 1.2 months respectively, P = 0.016; median overall survival 10.9 months vs 2.1 months respectively, P < 0.001). In the multivariate analysis, age (60 years or older), Eastern Cooperative Oncology Group performance status (2 or greater), and the RMH prognostic score (2 or 3) were significant predictors of poor survival. CONCLUSIONS: The RMH prognostic score is a strong tool to predict the prognosis of esophagogastric cancer patients who might participate in a phase 1 trial.

RESUMO

PURPOSE: The NCI Cancer Therapy Evaluation Program sponsors hepatic dysfunction phase I clinical trials (HDCT) and phase 1 clinical trials (P1CT) to determine safe doses and schedules of antineoplastic therapeutics. We sought to compare clinical outcomes between these trial types while stratifying by hepatotoxic agents. EXPERIMENTAL DESIGN: Individual subject data were extracted from the records of 51 NCI-sponsored HDCT and P1CT. The NCI's Organ Dysfunction Working Group's hepatic impairment categorization and two drug-induced liver injury (DILI) scales (FDA R ratio and Hy's law) were used to classify subjects. The number of cycles administered and treatment discontinuation reason were also evaluated and compared between groups. RESULTS: There were 513 and 1,328 subjects treated on HDCT (n = 9) and P1CT (n = 42), respectively. There were differing patterns of DILI with significant worsening of total bilirubin in subjects on HDCT, and worsening of alanine aminotransferase (ALT) in subjects on P1CT. Cholestatic peak patterns of liver impairment (predominant increases in alkaline phosphatase rather than transaminases) were more frequent in HDCT. Criteria for Hy's law were met by 11 subjects on P1CT, but not by any subjects on HDCT. Disease progression was the most common reason for treatment discontinuation, followed by adverse events at similar frequencies in both HDCT and P1CT. CONCLUSIONS: The differential effects on hepatotoxicity suggest that underlying hepatic function may affect susceptibility to and patterns of DILI. The incorporation of additional measures of hepatic function may help identify those at highest risk of hepatotoxicity in future trials because baseline liver tests did not.

RESUMO

BACKGROUND: Hospice provides intensive end-of-life care to patients and their families delivered by an interdisciplinary team of nurses, aides, chaplains, social workers, and physicians. Significant gaps remain about how team members respond to diverse needs of patients and families, especially in the last week of life. OBJECTIVE: The study objective was to describe the frequency of hospice team provider visits in the last week of life, to examine changes in frequency over time, and to identify patient characteristics that were associated with an increase in visit frequency. DESIGN: This was a retrospective cohort study using electronic medical record data. SETTING/SUBJECTS: From U.S. not-for-profit hospices, 92,250 records were used of patients who died at home or in a nursing home, with a length of stay of at least seven days. MEASUREMENTS: Data included basic demographic variables, diagnoses, clinical markers of illness severity, patient functioning, and number of hospice team member visits in the last seven days of life. RESULTS: On average the total number of hospice team member visits in the last week of life was 1.36 visits/day. Most were nurse visits, followed by aides, social workers, and chaplains. Visits increased over each day on average across the last week of life. Greater increase in visits was associated with patients who were younger, male, Caucasian, had a spouse caregiver, and shorter lengths of stay. CONCLUSIONS: This study provides important information to help hospices align the interdisciplinary team configuration with the timing of team member visits, to better meet the needs of the patients and families they serve.

RESUMO

BACKGROUND: Dermatologic adverse events (AEs) can be key determinants of overall drug tolerability and of the maximum tolerated and recommended phase 2 doses in phase 1 trials. The authors present the largest dedicated analysis of dermatologic AEs on phase 1 trials to date. METHODS: Data from a prospectively maintained database of patients with solid tumors who were enrolled onto Cancer Therapeutics Evaluation Program (CTEP)-sponsored phase 1 trials of cytotoxic or molecularly targeted agents (MTAs) from 2000 to 2010 were analyzed. Cumulative incidence, site, and type of drug-related dermatologic AEs were described and compared. The timing of worst drug-related dermatologic AEs was summarized. RESULTS: In total, 3517 patients with solid tumors and 6165 unique, drug-related dermatologic AEs were analyzed, including 1545 patients on MTA-only trials, 671 on cytotoxic-only trials, and 1392 on combination MTA and cytotoxic trials. Of 1270 patients who had drug-related dermatologic events, the timing of the worst AE was as follows: 743 (cycle 1), 303 (cycle 2), and 224 (cycle 3 or later). Although the cumulative incidence of grade ≥3 drug-related AEs increased to 2.4% by cycle 6, it was only 1.6% at the end of cycle 1. The cumulative incidence of drug-related AEs was highest in patients who received MTA-only therapy (P < .001) and differed by dose level (P < .001). In patients who received MTA-only therapy, drug-related AEs were most common for combination kinase inhibitor-containing therapy (P < .001). CONCLUSIONS: A substantial proportion of drug-related dermatologic AEs occur after the traditional dose-limiting toxicity monitoring period of phase 1 clinical trials. Future designs should account for late toxicities.

RESUMO

BACKGROUND: Therapy for acute myeloid leukemia (AML) has largely remained unchanged, and outcomes are unsatisfactory. We sought to analyze outcomes of AML patients enrolled in phase I studies to determine whether overall response rates (ORR) and mortality rates have changed over time. METHODS: A retrospective analysis was performed on 711 adult AML patients enrolling in 45 phase I clinical trials supported by the Cancer Therapy Evaluation Program of the National Cancer Institute from 1986 to 2009. Changes in ORR and mortality rates for patients enrolled in 1986 to 1990, 1991 to 1995, 1996 to 2000, 2001 to 2005, and 2006 to 2009 were estimated with multivariable logistic regression models. All statistical tests were two-sided. RESULTS: There was a statistically significant increase in AML patients enrolling in phase I clinical trials over time (1986 to 1990: n = 61; 2006 to 2009: n = 256; P = .03). The ORR for the entire cohort was 15.4% (1986 to 1990: 8.9%, 1991 to 1995: 21.1%; 1996 to 2000: 7.0%; 2001 to 2005: 10.0%; 2006 to 2009: 22.6%), and it statistically significantly improved over time (P < .001). There was a statistically significant improvement in ORRs with novel agents in combination vs single agents (ORR = 22.8% vs 4.7%, respectively, odds ratio = 5.95, 95% confidence interval = 3.22 to 11.9, P < .001). The 60-day mortality rate for the entire cohort was 22.6%, but it statistically significantly improved over time (P = .009). CONCLUSIONS: There has been an encouraging increase in AML patients enrolling in phase I clinical studies over time. The improvement in ORRs appears to be partly because of the increase in combination trials and the inclusion of previously untreated poor-risk AML. Continued enrollment of AML patients in early phase clinical trials is vital for drug development and improvement in therapeutic outcomes.

RESUMO

This article describes the process of developing a suicide guideline in palliative care. Little literature was available, but utilizing the partnership model, a working party consulted with each discipline regarding specific requirements. The working party experienced significant challenges in creating policy that would adequately cover the diverse needs of all members of the palliative care team, as it was recognized that all staff needed guidance. The final guideline incorporated specific action plans for each discipline; mandatory training for all staff was endorsed through a recognized suicide alertness training program; advanced training in suicide intervention skills for key clinical staff will be required; and a "Rapid Plan Team" was recommended. This policy development has required significant work and the combined expertise of many disciplines.

RESUMO

PURPOSE: Fit-for-purpose pharmacodynamic biomarkers could expedite development of combination antiangiogenic regimens. Plasma sVEGFR2 concentrations ([sVEGFR2]) mark sunitinib effects on the systemic vasculature. We hypothesized that cilengitide would impair microvasculature recovery during sunitinib withdrawal and could be detected through changes in [sVEGFR2]. EXPERIMENTAL DESIGN: Advanced solid tumor patients received 50 mg sunitinib daily for 14 days. For the next 14 days, patients were randomized to arm A (cilengitide 2,000 mg administered intravenously twice weekly) or arm B (no treatment). The primary endpoint was change in [sVEGFR2] between days 14 and 28. A candidate pharmacodynamic biomarker of cilengitide inhibition of integrin αvß3, serum c-telopeptide collagen crosslinks (CTx), was also measured. RESULTS: Of 21 patients, 14 (7 per arm) received all treatments without interruption and had all blood samples available for analysis. The mean change and SD of [sVEGFR2] for all sunitinib-treated patients was consistent with previous data. There was no significant difference in the mean change in [sVEGFR2] from days 14 to 28 between the arms [arm A: 2.8 ng/mL; 95% confidence interval (CI), 2.1-3.6 vs. arm B: 2.0 ng/mL; 95% CI, 0.72-3.4; P = 0.22, 2-sample t test]. Additional analyses suggested (i) prior bevacizumab therapy to be associated with unusually low baseline [sVEGFR2] and (ii) sunitinib causes measurable changes in CTx. CONCLUSIONS: Cilengitide had no measurable effects on any circulating biomarkers. Sunitinib caused measurable declines in serum CTx. The properties of [sVEGFR2] and CTx observed in this study inform the design of future combination antiangiogenic therapy trials.

RESUMO

OBJECTIVES: To compare residents of assisted living facilities receiving hospice with people receiving hospice care at home. DESIGN: Electronic health record-based retrospective cohort study. SETTING: Nonprofit hospices in the Coalition of Hospices Organized to Investigate Comparative Effectiveness network. PARTICIPANTS: Individuals admitted to hospice between January 1, 2008, and May 15, 2012 (N = 85,581; 7,451 (8.7%) assisted living facility, 78,130 (91.3%) home). MEASUREMENTS: Hospice length of stay, use of opioids for pain, and site of death. RESULTS: The assisted living population was more likely than the home hospice population to have a diagnosis of dementia (23.5% vs 4.7%; odds ratio (OR) = 13.3, 95% confidence interval (CI) = 12.3-14.4; P < .001) and enroll in hospice closer to death (median length of stay 24 vs 29 days). Assisted living residents were less likely to receive opioids for pain (18.1% vs 39.7%; OR = 0.33, 95% CI = 0.29-0.39, P < .001) and less likely to die in an inpatient hospice unit (9.3% vs 16.1%; OR = 0.53, 95% CI = 0.49-0.58, P < .001) or a hospital (1.3% vs 7.6%; OR = 0.16, 95% CI = 0.13-0.19, P < .001). CONCLUSION: Three are several differences between residents of assisted living receiving hospice care and individuals living at home receiving hospice care. A better understanding of these differences could allow hospices to develop guidelines for better coordination of end-of-life care for the assisted living population.

RESUMO

CONTEXT: In the U. S., hospices sometimes provide high-intensity "continuous care" in patients' homes. However, little is known about the way that continuous care is used or what impact continuous care has on patient outcomes. OBJECTIVES: To describe patients who receive continuous care and determine whether continuous care reduces the likelihood that patients will die in an inpatient unit or hospital. METHODS: Data from 147,137 patients admitted to 11 U.S. hospices between 2008 and 2012 were extracted from the electronic medical records. The hospices are part of a research-focused collaboration. The study used a propensity score-matched cohort design. RESULTS: A total of 99,687 (67.8%) patients were in a private home or nursing home on the day before death, and of these, 10,140 (10.2%) received continuous care on the day before death. A propensity score-matched sample (n = 24,658) included 8524 patients who received continuous care and 16,134 patients who received routine care on the day before death. Using the two matched groups, patients who received continuous care on the day before death were significantly less likely to die in an inpatient hospice setting (350/8524 vs. 2030/16,134; 4.1% vs. 12.6%) (odds ratio [OR] 0.29; 95% CI 0.27-0.34; P < 0.001). When patients were cared for by a spouse, the use of continuous care was associated with a larger decrease in inpatient deaths (OR 0.12; 95% CI 0.09-0.16; P < 0.001) compared with those patients cared for by other family members (OR 0.37; 95% CI 0.32-0.42; P < 0.001). It is possible that unmeasured covariates were not included in the propensity score match. CONCLUSION: Use of continuous care on the day before death is associated with a significant reduction in the use of inpatient care on the last day of life, particularly when patients are cared for by a spouse.
