RESUMEN

BACKGROUND: Older adults (age ≥65 years) receiving chemotherapy are at risk for hospitalization. Predictors of unplanned hospitalization among older adults receiving chemotherapy for cancer were recently published using data from a study conducted by the Cancer and Aging Research Group (CARG). Our study aimed to externally validate these predictors in an independent cohort including older adults with advanced cancer receiving chemotherapy. METHODS: This validation cohort included patients (n=369) from the GAP70+ trial usual care arm. Enrolled patients were aged ≥70 years with incurable cancer and were starting a new line of chemotherapy. Previously identified risk factors proposed by the CARG study were ≥3 comorbidities, albumin level <3.5 g/dL, creatinine clearance <60 mL/min, gastrointestinal cancer, ≥5 medications, requiring assistance with activities of daily activities (ADLs), and having someone available to take them to the doctor (ie, presence of social support). The primary outcome was unplanned hospitalization within 3 months of treatment initiation. Multivariable logistic regression was applied including the 7 identified risk factors. Discriminative ability of the fitted model was performed by calculating the area under the receiver operating characteristic (AUC) curve. RESULTS: Mean age of the cohort was 77 years, 45% of patients were women, and 29% experienced unplanned hospitalization within the first 3 months of treatment. The proportions of hospitalized patients with 0-3, 4-5, and 6-7 identified risk factors were 24%, 28%, and 47%, respectively (P=.04). Impaired ADLs (odds ratio, 1.76; 95% CI, 1.04-2.99) and albumin level <3.5 g/dL (odds ratio, 2.23; 95% CI, 1.37-3.62) were significantly associated with increased odds of unplanned hospitalization. The AUC of the model, including the 7 identified risk factors, was 0.65 (95% CI, 0.59-0.71). CONCLUSIONS: The presence of a higher number of risk factors was associated with increased odds of unplanned hospitalization. This association was largely driven by impairment in ADLs and low albumin level. Validated predictors of unplanned hospitalization can help with counseling and shared decision-making with patients and their caregivers. CLINICALTRIALS: gov identifier: NCT02054741.

RESUMEN

Cross-linking combined with mass spectrometry (XL-MS) provides a wealth of information about the three-dimensional (3D) structure of proteins and their interactions. We introduce MaxLynx, a novel computational proteomics workflow for XL-MS integrated into the MaxQuant environment. It is applicable to noncleavable and MS-cleavable cross-linkers. For both, we have generalized the Andromeda peptide database search engine to efficiently identify cross-linked peptides. For noncleavable peptides, we implemented a novel dipeptide Andromeda score, which is the basis for a computationally efficient N-squared search engine. Additionally, partial scores summarize the evidence for the two constituents of the dipeptide individually. A posterior error probability (PEP) based on total and partial scores is used to control false discovery rates (FDRs). For MS-cleavable cross-linkers, a score of signature peaks is combined with the conventional Andromeda score on the cleavage products. The MaxQuant 3D peak detection was improved to ensure more accurate determination of the monoisotopic peak of isotope patterns for heavy molecules, which cross-linked peptides typically are. A wide selection of filtering parameters can replace the manual filtering of identifications, which is often necessary when using other pipelines. On benchmark data sets of synthetic peptides, MaxLynx outperforms all other tested software on data for both types of cross-linkers and on a proteome-wide data set of cross-linked Drosophila melanogaster cell lysate. The workflow also supports ion mobility-enhanced MS data. MaxLynx runs on Windows and Linux, contains an interactive viewer for displaying annotated cross-linked spectra, and is freely available at https://www.maxquant.org/.

RESUMEN

The PRoteomics IDEntifications (PRIDE) database (https://www.ebi.ac.uk/pride/) is the world's largest data repository of mass spectrometry-based proteomics data, and is one of the founding members of the global ProteomeXchange (PX) consortium. In this manuscript, we summarize the developments in PRIDE resources and related tools since the previous update manuscript was published in Nucleic Acids Research in 2016. In the last 3 years, public data sharing through PRIDE (as part of PX) has definitely become the norm in the field. In parallel, data re-use of public proteomics data has increased enormously, with multiple applications. We first describe the new architecture of PRIDE Archive, the archival component of PRIDE. PRIDE Archive and the related data submission framework have been further developed to support the increase in submitted data volumes and additional data types. A new scalable and fault tolerant storage backend, Application Programming Interface and web interface have been implemented, as a part of an ongoing process. Additionally, we emphasize the improved support for quantitative proteomics data through the mzTab format. At last, we outline key statistics on the current data contents and volume of downloads, and how PRIDE data are starting to be disseminated to added-value resources including Ensembl, UniProt and Expression Atlas.

RESUMEN

Chemical cross-linking analyzed by mass spectrometry (XL-MS) has become an important tool in unravelling protein structure, dynamics, and complex formation. Because the analysis of cross-linked proteins with mass spectrometry results in specific computational challenges, many computational tools have been developed to identify cross-linked peptides from mass spectra and subsequently interpret the identified cross-links within their structural context. In this review, we will provide an overview of the different tools that are currently available to tackle the computational part of an XL-MS experiment. First, we give an introduction on the computational challenges encountered when processing data from a cross-linking experiment. We then discuss available tools to identify peptides that are linked by intact or MS-cleavable cross-linkers, and we provide an overview of tools to interpret cross-linked peptides in the context of protein structure. Finally, we give an outlook on data management and dissemination challenges and opportunities for cross-linking experiments.

RESUMEN

INTRODUCTION: Hyperacusis is defined as a reduction in tolerance to ordinary environmental sounds. Hyperacusis can occur in individuals of all age groups, making daily life difficult for the sufferers. Although there is no objective test to accurately diagnose hyperacusis, questionnaires are useful for the assessment of hyperacusis. The aim of this study was to explore the reduced sound tolerance in university students using a hyperacusis questionnaire (HQ). MATERIALS AND METHODS: A total of 536 university students (300 females and 236 males) aged between 18 and 25 years, with a mean age of 21.34 ± 1.87 years, were assessed using an HQ developed by Khalfa. The mean total score of all the participants was 16.34 ± 7.91, and 5.78% of the participants had total scores indicating hyperacusis, where a majority of them were females. RESULTS: Females had significantly higher scores than men in terms of both the total and the attentional and emotional dimensions. The scores of the participants who reported noise exposure or a decrease in their tolerance to noise were significantly higher than those of the other participants. Even among young adults, there was a group of participants suffering from some problems related to decreased tolerance to everyday sounds. DISCUSSION: Although the Turkish translation of the HQ seems to be a reliable tool for evaluating hyperacusis in young adults, further work with various populations of different age groups is required to establish validity and to assess the psychometric qualities of the Turkish form.

RESUMEN

Shotgun proteomics experiments often take the form of a differential analysis, where two or more samples are compared against each other. The objective is to identify proteins that are either unique to a specific sample or a set of samples (qualitative differential proteomics), or that are significantly differentially expressed in one or more samples (quantitative differential proteomics). However, the success depends on the availability of a reliable protein sequence database for each sample. To perform such an analysis in the absence of a database, we here propose a novel, generic pipeline comprising an adapted spectral similarity score derived from database search algorithms that compares samples at the spectrum level to detect unique spectra. We applied our pipeline to compare two parasitic tapeworms: Taenia solium and Taenia hydatigena, of which only the former poses a threat to humans. Furthermore, because the genome of T. solium recently became available, we were able to prove the effectiveness and reliability of our pipeline a posteriori.

RESUMEN

Chemical cross-linking coupled with mass spectrometry plays an important role in unravelling protein interactions, especially weak and transient ones. Moreover, cross-linking complements several structural determination approaches such as cryo-EM. Although several computational approaches are available for the annotation of spectra obtained from cross-linked peptides, there remains room for improvement. Here, we present Xilmass, a novel algorithm to identify cross-linked peptides that introduces two new concepts: (i) the cross-linked peptides are represented in the search database such that the cross-linking sites are explicitly encoded, and (ii) the scoring function derived from the Andromeda algorithm was adapted to score against a theoretical tandem mass spectrometry (MS/MS) spectrum that contains the peaks from all possible fragment ions of a cross-linked peptide pair. The performance of Xilmass was evaluated against the recently published Kojak and the popular pLink algorithms on a calmodulin-plectin complex data set, as well as three additional, published data sets. The results show that Xilmass typically had the highest number of identified distinct cross-linked sites and also the highest number of predicted cross-linked sites.

RESUMEN

The increase in the prevalence of epidemic strains of methicillin resistant Staphylococcus aureus (MRSA) in hospitals and community requires special attention of infection control. The aim of this study was to determine the pathogenic phenotype (i.e. infectivity and resistotype) and genotypic characteristics (i.e. PFGE-pulsotyping, SLST-spa typing, MLST-sequence typing, eBURST-clonal complex detection algorithm) of clinical MRSA isolates in the Central Blacksea region of Turkey, in order to understand their short- and long-term epidemiological and evolutionary dynamics, and to investigate any probable presence of a significant clustering. This prospective study included consecutive but non-repetitive 48 MRSA isolates (of them 18 were colonized strains and 30 were causes of nosocomial infection) and seven methicillin-susceptible S.aureus (MSSA, all were isolated from nosocomial infection), collected between December 2006-February 2007 period from hospitalized patients. Identification of the isolates were performed by Vitek-2 automated system (BioMérieux, USA), and in vitro antimicrobial susceptibility testing by broth microdilution method and Vitek-2 automated system. The MRSA isolates found susceptible to erythromycin (n= 10) were further investigated for the presence of ermA gene by the PCR method. All the strains were typed by spa-typing and PFGE-pulsotyping methods. Among the isolates with different spa-types, representatives were selected (3 MRSA, 7 MSSA) and typed with MLST typing method. Among the isolates with different spa-types, representatives with different antimicrobial susceptibility patterns were selected (n= 8), and SCCmec types were determined by the multiplex PCR method. Antimicrobial resistance patterns of the isolates were digitized to get standardized antimicrobial resistance phenotypes. Clustering of MRSA isolates in pattern groups on the basis of discriminatory characteristics, namely infectivity, phenotype and genotype were statistically analyzed with specific inclusion and exclusion criteria. As a result, three different antimicrobial resistance phenotypes were found in MSSA isolates, whereas 13 were identified in MRSA isolates. In MSSA isolates, seven different PFGE-pulsotypes were detected, as compared to 14 pulsotypes in MRSA isolates. Among MRSA isolates, 10 sporadic strains with single PFGE-pulsotypes were detected. All MRSA isolates, with two exceptions (t459, t632), were of t030 spa-type; in the MLST analysis of the representatives of different spa-types (n= 3), a single type of MLST-clonal complex (CC8) and single MLST-sequence type (ST239) were identified. Each of the seven MSSA isolates yielded different spa-types, MLST-clonal complex types and MLST-sequence types (t777-ST5-CC5; t660-ST25-CC5; t153-ST34-CC30; t015-ST45-CC45; t267-ST97-CC97; t377-ST360-CC8; t084-ST15-C15). In the statistical analysis of 38 non-sporadic MRSA isolates, the isolates in Group-13 (n= 16; infectious, resistotype 14, pulsotype 4; antimicrobial resistance score= 24) displayed significant infectivity-phenotype-genotype clustering (p< 0.001). In 27 of the MRSA isolates, decreased susceptibility to teicoplanin (MIC= 4 µg/mL) was detected. Although, global MRSA isolates belonging to MLST-CC8, MLST-ST239, t030 spa-type were usually expected to be resistant to erythromycin, 10 such strains were erythromycin susceptible. However, ermA gene was found in six of these 10 strains, leading to a conclusion that the ermA gene of these isolates might be dysfunctional due to a point mutation or deletion. Selected representatives of MRSA isolates with different antimicrobial susceptibility patterns (n= 8) were detected to be SCCmec type III. In conclusion, S.aureus isolates in the patient population of our hospital representing the Central Blacksea region showed statistically significant clustering in infectivity, antimicrobial resistance phenotype and clonal genotype (p< 0.001). The dominant MRSA clone was ST239 which was one of the five major pandemic MRSA clones. Nosocomial MSSA isolates displayed long-term clonal diversity. This study produced regional evolutionary-epidemiological data that may support further regional, national and international long-term surveillance studies of S.aureus strains.

RESUMEN

PURPOSE: The primary goal of this scoping review was to summarize the literature published after the 2018 National Cancer Institute think tank, "Measuring Aging and Identifying Aging Phenotypes in Cancer Survivors," on physical and cognitive functional outcomes among cancer survivors treated with chemotherapy. We focused on the influence of chemotherapy on aging-related outcomes (i.e., physical functional outcomes, cognitive functional outcomes, and frailty), given the known associations between chemotherapy and biologic mechanisms that affect aging-related physiologic processes. METHODS: A search was conducted across electronic databases, including PubMed, Scopus, and Web of Science, for manuscripts published between August 2018 and July 2023. Eligible studies: 1) included physical function, cognitive function, and/or frailty as outcomes; 2) included cancer survivors (as either the whole sample or a subgroup); 3) reported on physical or cognitive functional outcomes and/or frailty related to chemotherapy treatment (as either the whole sample or a subgroup); and 4) were observational in study design. RESULTS: The search yielded 989 potentially relevant articles, of which 65 met the eligibility criteria. Of the 65 studies, 49 were longitudinal, and 16 were cross-sectional; 30 studies (46%) focused on breast cancer, 20 studies (31%) focused on the age group 60 + years, and 17 (26%) focused on childhood cancer survivors. With regards to outcomes, 82% of 23 studies reporting on physical function showed reduced physical function, 74% of 39 studies reporting on cognitive functional outcomes found reduced cognitive function, and 80% of 15 studies reporting on frailty found increasing frailty among cancer survivors treated with chemotherapy over time and/or compared to individuals not treated with chemotherapy. Fourteen studies (22%) evaluated biologic mechanisms and their relationship to aging-related outcomes. Inflammation was consistently associated with worsening physical and cognitive functional outcomes and epigenetic age increases. Further, DNA damage was consistently associated with worse aging-related outcomes. CONCLUSION: Chemotherapy is associated with reduced physical function, reduced cognitive function, and an increase in frailty in cancer survivors; these associations were demonstrated in longitudinal and cross-sectional studies. Inflammation and epigenetic age acceleration are associated with worse physical and cognitive function; prospective observational studies with multiple time points are needed to confirm these findings. IMPLICATIONS FOR CANCER SURVIVORS: This scoping review highlights the need for interventions to prevent declines in physical and cognitive function in cancer survivors who have received chemotherapy.

RESUMEN

The use of internal calibrants (the so-called lock mass approach) provides much greater accuracy in mass spectrometry based proteomics. However, the polydimethylcyclosiloxane (PCM) peaks commonly used for this purpose are quite unreliable, leading to missing calibrant peaks in spectra and correspondingly lower mass measurement accuracy. Therefore, we here introduce a universally applicable and robust internal calibrant, the tripeptide Asn3. We show that Asn3 is a substantial improvement over PCM both in terms of consistent detection and resulting mass measurement accuracy. Asn3 is also very easy to adopt in the lab, as it requires only minor adjustments to the analytical setup.

RESUMEN

INTRODUCTION: Aging-related concerns can increase the risk of treatment toxicities among older adults considering adjuvant chemotherapy. We previously demonstrated that older adults with cancer who reported feeling older than their chronological age (i.e., self-perceived age) were more likely to have aging-related concerns identified during a geriatric assessment. We explored how decisions about adjuvant chemotherapy vary with or are related to older adults' self-perceived age. MATERIALS AND METHODS: We conducted a secondary analysis of a multi-phased feasibility pilot using semi-structured interviews that were conducted to explore the patient decision-making process for adjuvant chemotherapy. Interviews incorporated questions about chronological and perceived age as factors for decision-making. Patient eligibility for the study included (1) age ≥ 70 years and older, (2) a diagnosis of breast, colon, or lung cancer and considering adjuvant chemotherapy, and (3) able to read size 18 font in English. Interview data were analyzed using constant comparative method. RESULTS: Twenty-one patients were enrolled. The mean chronological age was 78 years (range 71-91). The average perceived age of patients was 57 years (range 21-80). Eleven patients chose to receive treatment while ten patients did not. Aging-related themes illustrated that self-perceived age plays an important role when patients make decisions about adjuvant chemotherapy. More specifically, patients who reported their self-perceived age as younger than their chronological age also reported better perceived health status and chose to receive adjuvant chemotherapy. DISCUSSION: Patients' experiences of aging and self-perceived age may have different implications for decision-making.

RESUMEN

PURPOSE: We described information technology support and use of telemedicine for cancer care and research purposes at community oncology practices within the National Cancer Institute Community Oncology Research Program (NCORP). METHODS: We used data from the NCORP 2017 and 2022 Landscape Assessments. Separate logistic regression models were used to assess factors associated with the use of telemedicine for delivery of cancer care in 2017 and for research purposes in 2022 (cancer care delivery not assessed in 2022). RESULTS: Information was available from 210 and 259 practice groups excluding pediatric-only groups in 2017 and 2022, respectively. In 2017, 30% of practice groups used telemedicine for delivery of cancer care; half of these (15% overall) could use telemedicine for research purposes. In 2022, telemedicine was used for research purposes in 73% of practice groups. In multivariable models, self-identifying as a safety-net hospital was associated with a lower odd of telemedicine use for delivery of cancer care (adjusted odds ratio [AOR], 0.39; 95% CI, 0.17 to 0.93), whereas affiliation with a designated critical access hospital was associated with a higher odd of telemedicine use for delivery of cancer care (AOR, 2.29; 95% CI, 1.10 to 4.76). Having a general survivorship clinic (AOR, 1.92; 95% CI, 1.04 to 3.54) and number of oncology providers (increase per 10 providers; AOR, 1.32; 95% CI, 1.05 to 1.65) were associated with telemedicine use for research purposes. CONCLUSION: Almost one third of NCORP practice groups used telemedicine for cancer care delivery in 2017. In 2022, there is high capacity among NCORP practices (almost three-quarters) to use telemedicine for research purposes, especially among practices with a general survivorship clinic and a greater provider number.

RESUMEN

OBJECTIVES: Explore how older patients utilize their social networks to inform prognostic understanding. METHODS: In a pilot study of adults (≥65 years old) with advanced cancer, 16 patients completed surveys, social network maps, and semi-structured interviews exploring with whom they preferred to communicate about their illness. Interviews were analyzed using open-coding, and codes were categorized into emergent themes. Social network maps and themes were analyzed via mixed-methods social network analysis (MMSNA). Three case examples with diverse network characteristics and communication patterns were selected for further analysis. RESULTS: Three overarching themes (i.e., prognostic understanding, social support, and therapeutic alliance) revealed that patients' prognostic understanding was strongly influenced by the quality of the social support patients perceived from members of their social networks. Patients demonstrated prognostic understanding when they reported close relationships and open communication with their network members. Case examples revealed some ways that patients sought information and had better sense of their prognosis when they had supportive social networks. CONCLUSION: Findings illustrate how understanding social networks may provide information on how older adults with cancer seek, share, and process prognostic information.

RESUMEN

BACKGROUND: The store-and-forward camera-based evaluation of the eye, or teleophthalmology, is an effective way to identify diabetic retinopathy, the leading cause of blindness in the United States, but uptake has been slow. Understanding the barriers to and facilitators of implementing teleophthalmology programs from those actively adopting, running, and sustaining such programs is important for widespread adoption. OBJECTIVE: This study aims to understand the factors that are important in introducing teleophthalmology to improve access to diagnostic eye care for patients with diabetes in primary care clinics by using implementation science. METHODS: This qualitative study in 3 urban, low-income, largely racial and ethnic minority-serving safety-net primary care clinics in Rochester, New York, interviewed nurses and physicians on implementing a teleophthalmology program by using questions informed by the Practical, Robust Implementation and Sustainability Model and the Consolidated Framework for Implementation Research. RESULTS: Primary care nurses operationalizing the program in their clinics saw increased work burden and a lack of self-efficacy as barriers. Continuous training on the teleophthalmology process for nurses, physicians, and administrative staff through in-service and peer training by champions and superusers were identified by interviewees as needs. Facilitators included the perceived convenience for the patient and a perceived educational advantage to the program, as it gave an opportunity for providers to discuss the importance of eye care with patients. Concerns in making and tracking referrals to ophthalmology because of challenges related to care coordination were highlighted. The financial aspects of the program (eg, patient coverage and care provider reimbursement) were unclear to many staff members, influencing adoption and sustainability. CONCLUSIONS: Streamlining processes and workflows, training and assigning adequate staff, effectively coordinating care between primary care and eye care to improve follow-ups, and ensuring financial viability can all help streamline the adoption of teleophthalmology.

RESUMEN

The population of older adults with cancer in the United States is rapidly increasing, which will have a substantial impact on the oncology and public health workforces across the cancer continuum, from prevention to end of life. Unfortunately, inequities in existing social structures that cause increased psychosocial stressors have led to disparities in the incidence of cancer and the morbidity and mortality of cancer for individuals from marginalized backgrounds. It is imperative that older adults, especially those from historically marginalized backgrounds, be adequately represented in all stages of cancer research to address health inequities. Continued efforts and progress toward achieving social justice and health equity require a deeper commitment to and better understanding of the impact of social determinants of health within the cancer domain. Undoubtedly, a more holistic and integrated view that extends beyond the biologic and genetic factors of health must be adopted for health entities to recognize the critical role of environmental, behavioral, and social determinants in cancer health disparities. Against this backdrop, this paper uses a life course approach to present a multifactorial framework for understanding and addressing cancer disparities in an effort to advance social justice and health equity for racially and ethnically diverse older adults.

RESUMEN

BACKGROUND: Little is known about how older adults (OA) with advanced cancer interact with social network members (NM), and the nature of communication. This qualitative study aimed to characterize the processes by which OAs with cancer engage with NMs regarding their illness. METHODS: OAs 65 + with advanced cancer and considering treatment (n = 29) and NMs (n = 18) underwent semi-structured interviews asking 1) about their illness understanding; 2) to identify NMs with whom OAs discuss health-related matters; and 3) to describe the content, process, and impact of those illness-related conversations. Three coders analyzed transcribed interviews. Codes were categorized and emergent themes were identified to generate hypotheses. RESULTS: OAs seek NMs with medical backgrounds for cancer-related information and NMs with personal experience of a serious illness for emotional support. Patients characterize geographical location, frequency of communication, and length of NM relationship as factors that influence the nature of support the NM provides. Additionally, differences emerged between OA and NM perspectives on the depth of conversations and decision-making. CONCLUSIONS: A better characterization of how OAs' seek and share information and support may improve medical communication, disease understanding, and support goals-concordant care.

RESUMEN

INTRODUCTION: Disparities in care of older adults in cancer treatment trials and emergency department (ED) use exist. This report provides a baseline description of older adults ≥65 years old who present to the ED with active cancer. MATERIALS AND METHODS: Planned secondary analysis of the Comprehensive Oncologic Emergencies Research Network observational ED cohort study sponsored by the National Cancer Institute. Of 1564 eligible adults with active cancer, 1075 patients were prospectively enrolled, of which 505 were ≥ 65 years old. We recruited this convenience sample from eighteen participating sites across the United States between February 1, 2016 and January 30, 2017. RESULTS: Compared to cancer patients younger than 65 years of age, older adults were more likely to be transported to the ED by emergency medical services, have a higher Charlson Comorbidity Index score, and be admitted despite no significant difference in acuity as measured by the Emergency Severity Index. Despite the higher admission rate, no significant difference was noted in hospitalization length of stay, 30-day mortality, ED revisit or hospital admission within 30 days after the index visit. Three of the top five ED diagnoses for older adults were symptom-related (fever of other and unknown origin, abdominal and pelvic pain, and pain in throat and chest). Despite this, older adults were less likely to report symptoms and less likely to receive symptomatic treatment for pain and nausea than the younger comparison group. Both younger and older adults reported a higher symptom burden on the patient reported Condensed Memorial Symptom Assessment Scale than to ED providers. When treating suspected infection, no differences were noted in regard to administration of antibiotics in the ED, admissions, or length of stay ≤2 days for those receiving ED antibiotics. DISCUSSION: We identified several differences between older (≥65 years old) and younger adults with active cancer seeking emergency care. Older adults frequently presented for symptom-related diagnoses but received fewer symptomatic interventions in the ED suggesting that important opportunities to improve the care of older adults with cancer in the ED exist.

RESUMEN

Background: Older adults with cancer use the emergency department (ED) for acute concerns. Objectives: Characterize the palliative care needs and clinical outcomes of advanced cancer patients in the ED. Design: A planned secondary data analysis of the Comprehensive Oncologic Emergencies Research Network (CONCERN) data. Settings/Subjects: Cancer patients who presented to the 18 CONCERN affiliated EDs in the United States. Measurements: Survey included demographics, cancer type, functional status, symptom burden, palliative and hospice care enrollment, and advance directive code status. Results: Of the total (674/1075, 62.3%) patients had advanced cancer and most were White (78.6%) and female (50.3%); median age was 64 (interquartile range 54-71) years. A small proportion of them were receiving palliative (6.5% [95% confidence interval; CI 3.0-7.6]; p = 0.005) and hospice (1.3% [95% CI 1.0-3.2]; p = 0.52) care and had a higher 30-day mortality rate (8.3%, [95% CI 6.2-10.4]). Conclusions: Patients with advanced cancer continue to present to the ED despite recommendations for early delivery of palliative care.
