The wooden artifacts from Schöningen's Spear Horizon and their place in human evolution.

Ethnographic records show that wooden tools played a pivotal role in the daily lives of hunter-gatherers including food procurement tools used in hunting (e.g., spears, throwing sticks) and gathering (e.g. digging sticks, bark peelers), as well as, domestic tools (e.g., handles, vessels). However, wood rarely survives in the archeological record, especially in Pleistocene contexts and knowledge of prehistoric hunter-gatherer lifeways is strongly biased by the survivorship of more resilient materials such as lithics and bones. Consequently, very few Paleolithic sites have produced wooden artifacts and among them, the site of Schöningen stands out due to its number and variety of wooden tools. The recovery of complete wooden spears and throwing sticks at this 300,000-y-old site (MIS 9) led to a paradigm shift in the hunter vs. scavenger debate. For the first time and almost 30 y after their discovery, this study introduces the complete wooden assemblage from Schöningen 13 II-4 known as the Spear Horizon. In total, 187 wooden artifacts could be identified from the Spear Horizon demonstrating a broad spectrum of wood-working techniques, including the splitting technique. A minimum of 20 hunting weapons is now recognized and two newly identified artifact types comprise 35 tools made on split woods, which were likely used in domestic activities. Schöningen 13 II-4 represents the largest Pleistocene wooden artifact assemblage worldwide and demonstrates the key role woodworking had in human evolution. Finally, our results considerably change the interpretation of the Pleistocene lakeshore site of Schöningen.

Danish value sets for the EORTC QLU-C10D utility instrument.

PURPOSE: In this study, we developed Danish utility weights for the European Organisation for Research and Treatment of Cancer (EORTC) QLU-C10D, a cancer-specific utility instrument based on the EORTC QLQ-C30. METHODS: Following a standardized methodology, 1001 adult participants from the Danish general population were quota-sampled and completed a cross-sectional web-based survey and discrete choice experiment (DCE). In the DCE, participants considered 16 choice sets constructed from the key 10 dimensions of the QLU-C10D and chose their preferred health state for each one. Utility weights were calculated using conditional logistic regression with correction for non-monotonicity. RESULTS: The sample (n = 1001) was representative of the Danish general population with regard to age and gender. The domains with the largest utility decrements, i.e., the domains with the biggest impact on health utility, were physical functioning (- 0.224), pain (- 0.160), and role functioning (- 0.136). The smallest utility decrements were observed for the domains lack of appetite (- 0.024), sleep disorders (- 0.057), and fatigue (- 0.064). Non-monotonicity of severity levels was observed for the domains sleep disturbances, lack of appetite, and bowel problems. Deviations from monotonicity were not statistically significant. CONCLUSION: The EORTC QLU-C10D is a relatively new multi-attribute utility instrument and is a promising cancer-specific health technology assessment candidate measure. The country-specific Danish utility weights from this study can be used for cost-utility analyses in Danish patients and for comparison with other country-specific utility data.

Usability of Electronic Patient-Reported Outcome Measures for Older Patients With Cancer: Secondary Analysis of Data from an Observational Single Center Study.

BACKGROUND: Patient-reported outcomes are considered the gold standard for assessing subjective health status in oncology patients. Electronic assessment of patient-reported outcomes (ePRO) has become increasingly popular in recent years in both clinical trials and practice. However, there is limited evidence on how well older patients with cancer can complete ePRO assessments. OBJECTIVE: We aimed to investigate how well adult patients with cancer of different age ranges could complete ePRO assessments at home and in a treatment facility and to identify factors associated with the ability to complete questionnaires electronically. METHODS: This retrospective longitudinal single-center study involved survivors of cancer who participated in inpatient rehabilitation. Patients completed ePRO assessments before rehabilitation at home (T1) and after rehabilitation at the facility (T2). We analyzed the rate of patients who could complete the ePRO assessment at T1 and T2, the proportion of patients who required assistance, and the time it took patients to complete standardized questionnaires. Multivariate logistic regression analyses were conducted to identify predictors of ePRO completion rate and the need for assistance. RESULTS: Between 2017 and 2022, a total of 5571 patients were included in this study. Patients had a mean age of 60.3 (SD 12.2) years (range 18 to 93 years), and 1135 (20.3%) of them were classified as geriatric patients (>70 years). While more than 90% (5060/5571) of all patients completed the ePRO assessment, fewer patients in the age group of >70 years (924/1135, 81.4% at T1 vs 963/1135, 84.8% at T2) completed the assessment. Approximately 19% (1056/5571) of patients reported a need for assistance with the ePRO assessment at home, compared to 6.8% (304/4483) at the institution. Patients older than 70 years had a significantly higher need for assistance than those in younger age groups. Moreover, a gender difference was observed, with older women reporting a higher need for assistance than men (71-80 years: women requiring assistance 215/482, 44.6% vs men 96/350, 27.4%; P<.001 and >80 years: women 102/141, 72.3% vs men 57/112, 50.9%; P<.001). On average, patients needed 4.9 (SD 3.20) minutes to remotely complete a 30-item questionnaire (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire) and patients in the older age groups took significantly longer compared to younger age groups. Lower age and higher physical functioning were the clearest predictors for both the ePRO completion rate and the need for assistance in the multivariate regression analysis. CONCLUSIONS: This study's results indicate that ePRO assessment is feasible in older individuals with cancer, but older patients may require assistance (eg, from relatives) to complete home-based assessments. It may be more feasible to conduct assessments in-house in this population. Additionally, it is crucial to carefully consider which resources are necessary and available to support patients in using ePRO devices.

The EORTC QLU-C10D: the Hong Kong valuation study.

OBJECTIVE: The EORTC QLU-C10D is a new preference-based measure derived from the EORTC QLQ-C30. Country-specific value sets are required to support the cost-utility analysis of cancer-related interventions. This study aimed to generate an EORTC QLU-C10 value set for Hong Kong (HK). METHODS: A HK online panel was quota-sampled to achieve an adult general population sample representative by sex and age. Participants were invited to complete an online discrete choice experiment survey. Each participant was asked to complete 16 choice-pairs, randomly assigned from a total of 960 choice-pairs, each comprising two QLU-C10D health states and a duration attribute. Conditional and mixed logistic regression analyses were used to analyse the data. RESULTS: The analysis included data from 1041 respondents who had successfully completed the online survey. The distribution of sex did not differ from that of the general population, but a significant difference was found among age groups. A weighting analysis for non-representative variable (age) was used. Utility decrements were generally monotonic, with the largest decrements for physical functioning (- 0.308), role functioning (- 0.165), and pain (- 0.161). The mean QLU-C10D utility score of the participants was 0.804 (median = 0.838, worst to best = - 0.169 to 1). The value of the worst health state was - 0.223, which was sufficiently lower than 0 (being dead). CONCLUSIONS: This study established HK utility weights for the QLU-C10D, which can facilitate cost-utility analyses across cancer-related health programmes and technologies.

Integration of Daily Patient-Reported Outcome Measures in Pediatric Stem Cell Transplantation.

Patients' reports of their health status are increasingly used in hematopoietic stem cell transplantation (SCT) to better understand the negative impact on symptom burden and quality of life. Little is known regarding the implementation in routine clinical care, particularly how it can be used to improve supportive care. We sought to the evaluate feasibility of capturing daily patient-reported outcomes (PROs) in the acute phase of SCT to measure physical and psychosocial symptom burden. In this single-center prospective observational study, we assessed daily PRO from conditioning to neutrophil engraftment in children (age 1 to 18 year) who underwent allogeneic or autologous SCT for malignant and nonmalignant disease. The most common acute adverse effects of chemotherapy (pain, nausea, loss of appetite, sleep disturbance, and physical performance impairment) were reported daily via ePROtect, a web-based program designed to integrate health responses. From February 2021 to March 2023, 20 children undergoing allogeneic (allo-) SCT (n = 11) or autologous (auto-) SCT (n = 9) and their proxies consented to participation, all of whom were included in this analysis. A total of 359 PRO questionnaires were completed, corresponding to a median daily completion rate of 72.7% (interquartile range, 60.4% to 83.6%). After conditioning, pain perception anticipated the rise of infectious parameters and the development of mucositis, thus initiating supportive treatment. Patients reported the strongest symptom burden at a median of 8.5 days post-transplantation. At 4 weeks post-transplantation, baseline values were restored for all symptoms. There were no significant differences between auto-SCT and allo-SCT, except for nausea and loss of appetite after administration of antithymocyte globulin in allo-SCT. This study empirically documents the daily health status of children undergoing SCT and proposes an attractive modus operandi on how continuous feedback on health-related symptoms can be integrated into daily clinical practice.

International validation of a health-related quality-of-life questionnaire for Hodgkin lymphoma: the EORTC QLQ-HL27.

Hodgkin lymphoma (HL) has become 1 of the most curable cancers. Therefore, rigorous assessment of health-related quality of life (HRQoL) and symptom burden of these patients is essential to support informed clinical decisions. The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group previously developed the EORTC Quality of Life Questionnaire (QLQ) Hodgkin Lymphoma 27. This paper reports the final results of an international study by the EORTC group to develop a HRQoL disease-specific measure for these patients: the EORTC QLQ-HL27. Patients with a confirmed diagnosis of HL (N = 381) were enrolled from 12 countries and completed the EORTC QLQ-C30, QLQ-HL27, and a debriefing questionnaire at baseline (any time after diagnosis). A subset completed a retest (n = 126) or responsiveness-to-change analyses (RCA) second measurement (n = 98). Psychometrics were evaluated. Confirmatory factor analysis showed an acceptable fit of the 27 items of the QLQ-HL27 on its 4 scales (symptom burden, physical condition/fatigue, emotional impact, and worries about health/functioning). Test-retest reliability, convergent validity, known-group comparisons, and RCA find satisfactory results. Symptom burden and fatigue was higher among patients on treatment (with 36%-83% reporting at least a few problems) compared with those who had completed treatment (19%-61% reporting at least a few problems). Prevalence of worries about health and functioning (reporting at least some worry) was similar for patients on treatment (51%-81%) vs those who had completed treatment (52%-78%). Implementation of the EORTC QLQ-HL27 in research and clinical applications will increase sensitivity of HRQoL assessment in patients with HL. High quality data generated through use of this questionnaire are expected to facilitate clinical decision making in the HL setting.

Adherence to Patient-Reported Symptom Monitoring and Subsequent Clinical Interventions for Patients With Multiple Myeloma in Outpatient Care: Longitudinal Observational Study.

BACKGROUND: The use of software to monitor patient-reported outcome measures (PROMs) can improve outcomes for patients with cancer receiving anticancer therapy; however, evidence from applications used in routine clinical practice is lacking. OBJECTIVE: We aimed to investigate adherence to and patient perceptions of a weekly, web-based PROM symptom monitoring program in routine clinical practice for patients with Multiple Myeloma. Moreover, we aimed to capture how clinical alerts prompted by the system influenced clinical care. METHODS: We conducted a single-center longitudinal observational study to evaluate patient adherence to and perceptions of the PROM monitoring software in routine practice. Patients with Multiple Myeloma remotely completed weekly treatment-specific PROMs to monitor key symptoms via a dedicated web-based platform. Alarming symptoms triggered clinical alerts in the application for the treatment team, which could initiate clinical interventions. The primary outcomes were the web-based assessment completion rate and patients' perceptions of the monitoring program, as assessed by an evaluation questionnaire. Moreover, clinical alerts prompted by the system and consequential clinical interventions were analyzed. RESULTS: Between July 2021 and June 2022, a total of 55 patients were approached for participation; 39 patients participated (24, 61% male, mean age 63.2, SD 9.2 years). The median assessment completion rate out of all weekly scheduled assessments was 70.3% (IQR 41.2%-89.6%). Most patients (77%) felt that the health care team was better informed about their health status due to the web-based assessments. Clinical alerts were triggered for 1758 of 14,639 (12%) reported symptoms. For 548 of 1758 (31.2%) alerts, the symptom had been registered before and no further action was required; for 348 of 1758 (19.9%) alerts, telephone consultation and self-management advice sufficed. Higher-level interventions were seldom needed in response to alerts: referral to a doctor or specialist (88/1758, 5% alerts), medication changes (22/1758, 1.3%), scheduling additional diagnostics (9/1758, 0.5%), or unplanned emergency visits (7/1758, 0.4%). Most patients (55%) reported the calls in response to alerts gave them "quite a bit" or "very much" of an added feeling of security during therapy. CONCLUSIONS: Our study shows that high adherence to regular and tailored PROM monitoring can be achieved in routine clinical care. The findings provide valuable insight into how the PROM monitoring program and the clinical alerts and resulting interventions shaped clinical practice.

A double-pointed wooden throwing stick from Schöningen, Germany: Results and new insights from a multianalytical study.

The site of Schöningen (Germany), dated to ca. 300,000 years ago, yielded the earliest large-scale record of humanly-made wooden tools. These include wooden spears and shorter double-pointed sticks, discovered in association with herbivores that were hunted and butchered along a lakeshore. Wooden tools have not been systematically analysed to the same standard as other Palaeolithic technologies, such as lithic or bone tools. Our multianalytical study includes micro-CT scanning, 3-dimensional microscopy, and Fourier transform infrared spectroscopy, supporting a systematic technological and taphonomic analysis, thus setting a new standard for wooden tool analysis. In illustrating the biography of one of Schöningen's double-pointed sticks, we demonstrate new human behaviours for this time period, including sophisticated woodworking techniques. The hominins selected a spruce branch which they then debarked and shaped into an aerodynamic and ergonomic tool. They likely seasoned the wood to avoid cracking and warping. After a long period of use, it was probably lost while hunting, and was then rapidly buried in mud. Taphonomic alterations include damage from trampling, fungal attack, root damage and compression. Through our detailed analysis we show that Middle Pleistocene humans had a rich awareness of raw material properties, and possessed sophisticated woodworking skills. Alongside new detailed morphometrics of the object, an ethnographic review supports a primary function as a throwing stick for hunting, indicating potential hunting strategies and social contexts including for communal hunts involving children. The Schöningen throwing sticks may have been used to strategically disadvantage larger ungulates, potentially from distances of up to 30 metres. They also demonstrate that the hominins were technologically capable of capturing smaller fast prey and avian fauna, a behaviour evidenced at contemporaneous Middle Pleistocene archaeological sites.

The effect of inflammation, SARS-CoV-2 infection, age and mental health on serotonin, and kynurenine and catecholamine pathway metabolites.

BACKGROUND: A high prevalence of mental disorders following COVID-19 has been described. It is therefore essential to elucidate underlying biological mechanisms linking SARS-CoV-2 infection and mental health. The kynurenine and catecholamine metabolic pathways are modulated by inflammation and can affect systemic levels of serotonin and dopamine. Their activity may hence link physical disorders with mental health. We investigated factors that affect kynurenine and catecholamine pathway activity in SARS-CoV-2 infection and recovery. METHODS: The cross-sectional SIMMUN (n = 165) and longitudinal INCOV cohort (n = 167, Su et al. 2022) were analyzed. Demographic and clinical characteristic, inflammatory markers, SARS-CoV-2 infection, symptoms of depression and anxiety (HADS), and mental stress (PSS-4) served as explanatory variables. Blood serotonin and markers of kynurenine (kynurenine/tryptophan ratio), and catecholamine pathway activity (dopamine 3-O-sulfate, phenylalanine/tyrosine ratio) were modeled by multi-parameter linear regression. RESULTS: In the SIMMUN cohort, the inflammatory marker neopterin (ß = 0.47 [95% CI: 0.34-0.61]), SARS-CoV-2-positivity (0.42 [0.16-0.68]), mental stress (0.18 [0.055-0.31]), and age (0.26 [0.12-0.39]) were positively associated with the kynurenine/tryptophan ratio. The phenylalanine/tyrosine ratio was lower in SARS-CoV-2-positive than uninfected participants (-0.38 [-0.68 to -0.08]). In the INCOV cohort, markers of inflammation were associated with lower serotonin (IL6: -0.22 [-0.38 to -0.053]) and dopamine 3-O-sulfate levels (interferon-gamma: -0.15 [-0.26 to -0.036]). Serotonin (0.76 [0.34-1.2]) and dopamine 3-O-sulfate levels (0.63 [0.28-0.99]) were higher during recovery than in acute SARS-CoV-2 infection. CONCLUSION: SARS-CoV-2 infection, inflammation, age and mental stress are key independent predictors of kynurenine pathway activity, which may influence serotonin availability. The catecholamine pathway was also affected in SARS-CoV-2 infection. Altered activity of these pathways may contribute to impaired mental health following COVID-19.

International validation of two EORTC questionnaires for assessment of health-related quality of life for patients with high-grade non-Hodgkin lymphoma (QLQ-NHL-HG29) and low-grade non-Hodgkin lymphoma (QLQ-NHL-LG20).

BACKGROUND: Health-related quality of life (HRQOL) is a critical aspect to consider when making treatment decisions for patients with non-Hodgkin-lymphoma (NHL). This international study by the European Organisation for Research and Treatment of Cancer (EORTC) tested the psychometric properties of two newly developed measures for patients with high-grade (HG)- and low-grade (LG)-NHL: the EORTC QLQ-NHL-HG29 and the EORTC QLQ-NHL-LG20 to supplement the core questionnaire (EORTC QLQ-C30). METHODS: Overall, 768 patients with HG-NHL (N = 423) and LG-NHL (N = 345) from 12 countries completed the QLQ-C30, QLQ-NHL-HG29/QLQ-NHL-LG20 and a debriefing questionnaire at baseline, and a subset at follow-up for either retest (N = 125/124) or responsiveness to change (RCA; N = 98/49). RESULTS: Confirmatory factor analysis showed an acceptable to good fit of the 29 items of the QLQ-NHL-HG29 on its five scales (symptom burden [SB], neuropathy, physical condition/fatigue [PF], emotional impact [EI], and worries about health/functioning [WH]), and of the 20 items of the QLQ-NHL-LG20 on its four scales (SB, PF, EI, and WH). Completion took on average 10 minutes. Test-retest reliability, convergent validity, known-group comparisons, and RCA find satisfactory results of both measures. A total of 31%-78% of patients with HG-NHL and 22%-73% of patients with LG-NHL reported symptoms and/or worries (e.g., tingling in hands/feet, lack of energy, and worries about recurrence). Patients reporting symptoms/worries had substantially lower HRQOL compared to those without. DISCUSSION: The use of the EORTC QLQ-NHL-HG29 and QLQ-NHL-LG20 questionnaires in clinical research and practice will provide clinically relevant data to better inform treatment decision-making. PLAIN LANGUAGE SUMMARY: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group developed two questionnaires. These questionnaires measure health-related quality of life. The questionnaires are for patients with high-grade or low-grade non-Hodgkin lymphoma. They are called the EORTC QLQ-NHL-HG29 and QLQ-NHL-LG20. The questionnaires are now internationally validated. This study demonstrates that the questionnaires are reliably and valid, which are important aspects of a questionnaire. The questionnaires can now be used in clinical trials and practice. With the information gathered from the questionnaires, patients and clinicians can better evaluate treatments and discuss the best choice for a patient.

Associations of Age and Sex with the Efficacy of Inpatient Cancer Rehabilitation: Results from a Longitudinal Observational Study Using Electronic Patient-Reported Outcomes.

Cancer rehabilitation is thought to increase the quality of life (QOL) and functioning of cancer survivors. It remains, however, uncertain whether subgroups benefit equally from rehabilitation. We wished to investigate the outcomes of multimodal rehabilitation according to age, sex and functioning. Patients of an Austrian rehabilitation center routinely completed the EORTC QLQ-C30 and the hospital anxiety and depression scale (HADS) questionnaires prior to (T1), and after rehabilitation (T2). To compare the outcomes between age groups (i.e., <40, 41-69, and ≥70 years), sex, and the Norton scale risk status, repeated measures of analyses of variance were calculated. A total of 5567 patients with an average age of 60.7 years were included, of which 62.7% were female. With T1 indicating the cancer survivors' needs, older and high-risk patients reported lower functioning (all p < 0.001) and a higher symptom burden for most scales (all p < 0.05) before rehabilitation. Regardless of age, sex or risk status, the patients showed at a least small to medium improvement during rehabilitation for anxiety, depression, and most functioning and symptom scales. Some between-group differences were observed, none of which being of a relevant effect size as determined with the Cohen's d. In conclusion, QOL is improved by rehabilitation in all patients groups, independently from age, sex, or the risk status.

Disagreement between mothers' and fathers' rating of health-related quality of life in children with cancer.

PURPOSE: Serial assessment of health condition based on self-report made by children and their proxies has consistently shown a lack of congruence. The study explored the discrepancies between mother's, father's, and children's reports on health-related quality of life (HRQOL) during the first two months of pediatric cancer treatment. METHODS: In this cohort study, children and parents completed the generic and cancer-specific Pediatric Quality-of-Life Inventory (PedsQL) questionnaires at initial diagnosis and in the subsequent months. Evaluation of discrepancies included intraclass correlations between mother-child and father-child dyads at different domain levels. RESULTS: Thirty-six children with a diagnosis of cancer between May 2020 and November 2021 and their parents were included in this study. At diagnosis, mother-child dyads showed better agreement on more domains of the PedsQL Generic Core Scale than father-child dyads; moderate agreement persisted for both parents at subsequent time points on the physical domain. The disease-specific PedsQL Cancer Module revealed moderate and better agreement for mother-child dyads during active cancer therapy. In particular, agreement of mother-child dyads was pronounced for domains such as worry (0.77 [95% CI 0.52-0.89, P < 0.001]), whereas fathers tended to overestimate the child's symptom burden for most of the remaining domains of the PedsQL Cancer Module. CONCLUSION: This cohort study shows that both parent proxy reports can provide valid information on child's HRQOL, but that fathers tend to overestimate, particularly for non-observable domains. Proxy reports derived from mothers more closely agreed with children's HRQOL and might be more weighted, if there is uncertainty between parents.

LogicENN: A Neural Based Knowledge Graphs Embedding Model With Logical Rules.

Knowledge graph embedding models have gained significant attention in AI research. The aim of knowledge graph embedding is to embed the graphs into a vector space in which the structure of the graph is preserved. Recent works have shown that the inclusion of background knowledge, such as logical rules, can improve the performance of embeddings in downstream machine learning tasks. However, so far, most existing models do not allow the inclusion of rules. We address the challenge of including rules and present a new neural based embedding model (LogicENN). We prove that LogicENN can learn every ground truth of encoded rules in a knowledge graph. To the best of our knowledge, this has not been proved so far for the neural based family of embedding models. Moreover, we derive formulae for the inclusion of various rules, including (anti-)symmetric, inverse, irreflexive and transitive, implication, composition, equivalence and negation. Our formulation allows to avoid grounding for implication and equivalence relations. Our experiments show that LogicENN outperforms the existing models in link prediction.

Use of Daily Patient-Reported Outcome Measurements in Pediatric Cancer Care.

Importance: Patient-reported outcome measurements (PROMs) are emerging as an important component of adult cancer care, but little has been done with regard to PROMs for pediatric cancer care. Objectives: To identify pediatric patients with cancer who are at risk of severe adverse effects of treatment and provide individualized supportive care using PROMs. Design, Setting, and Participants: This single-center cohort study with PROMs implemented in daily clinical routine was conducted from May 1, 2020, to November 15, 2021, among pediatric patients with a cancer diagnosis or their proxies. Inclusion criteria were treatment with chemotherapy and at least 30 days of active participation. Patients were followed up until completion of therapy or through ongoing therapy until November 15, 2021; data were analyzed from November 15, 2021, through January 31, 2022. Exposures: Cancer treatment, including chemotherapy, surgery, and radiotherapy. Main Outcomes and Measures: The primary outcome was occurrence and severity of ubiquitous complications of cancer treatment, such as nausea, appetite loss, pain, sleep disturbance, and deterioration of physical functioning. The secondary outcome was the identification of early and appropriate clinical interventions based on detection of cancer-related symptoms via PROMs. Results: A total of 4410 daily PROMs from 7082 therapy days for 40 children (35 children aged 5-18 years and 5 proxies for children aged 1-4 years) (median age, 9.1 [IQR, 6.3-12.2] years; 26 [65.0%] male) were analyzed during a median follow-up of 145.5 (IQR, 103.8-244.5) days. All participants were White. The overall median completion rate was 60.1% (IQR, 37.9%-81.0%); this rate was slightly lower during home care vs inpatient stay (57.5% [IQR, 30.7%-85.9%] vs 65.0% [IQR, 49.6%-92.5%], respectively; P = .01), with a decreasing trend over time (65.6% [IQR, 51.6%-85.9%] for the first 90 days vs 42.9% [IQR, 29.3%-82.3%] for beyond 90 days; P < .001). Severe symptoms were reported on 657 days (14.9%); most symptoms were associated with physical functioning, followed by pain, sleep disturbance, and nausea and appetite loss. In total, 321 adverse events (AEs) and cases of health deterioration were documented, and PROMs were completed for 251 (78.2%) of these events. Across all AEs, self-reported pain was the most useful marker, particularly when analyzed on the day before onset, and was associated with an odds ratio of 3.65 (95% CI, 1.54-8.62; P = .005) for the presence of mucositis. Conclusions and Relevance: The findings of this cohort study suggest that PROMs reflect daily symptoms in pediatric patients with cancer and assist in clinical management and intervention for AEs.

Patient-reported outcomes are under-utilised in evaluating supportive therapies in paediatric oncology - A systematic review of clinical trial registries.

BACKGROUND: Children with cancer suffer from numerous symptoms and side-effects, making supportive interventions indispensable to improve their quality of life. The gold standard for evaluating the latter is patient-reported outcome (PRO) assessment. This systematic review investigates the current practice of clinical outcome assessment (COA) in clinical trials on supportive interventions. METHODS: ClinicalTrials.gov and EudraCT were searched for trials including children and adolescents (≤21 years) with cancer receiving supportive care registered 2007-2020. The use of different types of COAs was analysed, focusing on PRO assessment and the domains measured with PRO measures (PROMs). Associations with trial characteristics were investigated using univariate and multivariable analyses. RESULTS: Of 4789 identified trials, 229 were included. Among them, 44.1 % relied on PROMs, the most commonly used COA. The proportion of trials using PROMs did not significantly differ over time. In the multivariable analysis, intervention type (higher PROM use in behavioural vs. medical interventional trials) and cancer type (higher PROM use in mixed and solid tumour samples vs. haematological samples) were significant predictors of PROM use. The majority of trials using PROMs (59.6 %) measured more than one health domain. 'Physical health' was the most frequently assessed domain (92.6 %). CONCLUSION: Less than half of registered clinical trials investigating supportive interventions for children with cancer used PROMs. This result is striking since supportive care explicitly focuses on patients' quality of life, which is best assessed using PROMs. Our systematic review underlines the need to identify barriers for PROM implementation and to improve PRO research in paediatric oncology.

Usability evaluation of the Computer-Based Health Evaluation System (CHES) eDiary for patients with faecal incontinence: a pilot study.

BACKGROUND: Faecal incontinence (FI) is prevalent in 15-20% of elderly individuals and is frequently monitored in clinical trials and practice. Bowel diaries are the most common way to document FI, but, in clinical practice, are mainly used as paper-based versions. Electronic diaries (eDiaries) offer many potential benefits over paper-based diaries. The aim of this study was to develop and test an eDiary to document FI. METHODS: We migrated a paper FI diary to an eDiary app based on the Computer-based Health Evaluation System (CHES). To assess usability, we conducted functionality and usability tests at two time points in a sample of patients with FI. In the first assessment, the eDiary functionalities were tested, patients completed the System Usability Scale (SUS, range 0-100) and compared the paper diary with the eDiary. We set a threshold for minimum acceptable average usability at 70 points. Patients were then instructed to use the eDiary for 2 days at home and contacted to report on their usage and completed the SUS a second time. RESULTS: We recruited a sample of N = 14 patients to use the eDiary. All patients were able to use all functionalities of the eDiary and only a few patients with lower technological literacy or access to devices (n = 3) needed initial assistance. The mean usability rating given at the first time point was high with 88 points (SD 18, 95% CI 78.2-96.8) and most patients (n = 10) reported they would prefer the eDiary over the paper-based version. Nine patients (n = 9) participated in the follow-up assessment and the mean SUS rating at the second time point was 97 points (SD 7, 95% CI 92.8-100). CONCLUSION: The eDiary showed excellent usability scores for the assessment of FI at both assessments. Generally, patients preferred the eDiary over the paper-based version. We recommend the eDiary for usage with patients who own and use a smartphone and discuss potential solutions for patients with lower technological literacy or access.

International validation of the EORTC QLQ-CLL17 questionnaire for assessment of health-related quality of life for patients with chronic lymphocytic leukaemia.

Selecting the most appropriate chronic lymphocytic leukaemia (CLL) treatment is challenging. Patient-reported health-related quality of life (HRQoL) is therefore a critical aspect to consider. This international study by the European Organization for Research and Treatment of Cancer (EORTC) tested the psychometric properties of a newly developed measure for CLL patients: the EORTC QLQ-CLL17 to supplement the core questionnaire (EORTC QLQ-C30). Patients with CLL (n = 341) from 12 countries completed the QLQ-C30, QLQ-CLL17 and a debriefing questionnaire. Sociodemographic and clinical data were recorded from medical records. A high percentage (30%-66%) reported symptoms and/or worries (e.g. aches/pains in muscles, lack of energy and worry/fears about health). Confirmatory factor analysis showed an acceptable to good fit of the 17 items on the three scales (i.e. symptom burden, physical condition/fatigue and worries/fears about health and functioning). Completion took on average 8 min. Test-retest and convergent validity was demonstrated. The QLQ-CLL17 differentiated between patients with an Eastern Cooperative Oncology group (ECOG) performance of 0 versus 1-3 (p's < 0.01 and clinically relevant). The newly developed EORTC QLQ-CLL17 will increase sensitivity of HRQoL assessment in patients with CLL. Implementation of this questionnaire both in clinical research and practice will help to generate unique clinically relevant data to better inform CLL treatment decision-making.

Geometric morphometric analysis of morphologic disparity, intraspecific variation and ontogenetic allometry of beyrichitine ammonoids.

Beyrichitine ammonoids of NV Nevada reveal a high taxonomic diversity of Anisian (Middle Triassic). This diversity is, however, in contrast to their relatively low morphologic disparity. Depending on the exact definition, morphologic disparity of a data set is a direct consequence of the sum of all ontogenetic changes. In the past, however, the interplay of both morphological processes has only rarely been addressed. Using geometric morphometric methods, this study aims at a quantification of allometric processes and the morphologic disparity of beyrichitine ammonoids. The multivariate statistical analysis revealed that morphologic disparity, intraspecific variation respectively, within and between the studied species seems to be the result of deviations in the ontogenetic allometric growth pattern (i.e. heterochrony). During deposition of the studied stratigraphic sequence, a general progressive pedomorphism (juvenilization) was observed. The intraspecific variability pattern coincides with the total morphologic disparity of the analyzed species, which suggests that intraspecific variability facilitated morphologic disparity. The comparison of ontogenetic allometric patterns and changes in intraspecific variation and morphologic disparity are likely to refine our understanding of the intrinsic factors influencing the speciation of this group.

Bringing Light Into the Dark: A Large-Scale Evaluation of Knowledge Graph Embedding Models Under a Unified Framework.

The heterogeneity in recently published knowledge graph embedding models' implementations, training, and evaluation has made fair and thorough comparisons difficult. To assess the reproducibility of previously published results, we re-implemented and evaluated 21 models in the PyKEEN software package. In this paper, we outline which results could be reproduced with their reported hyper-parameters, which could only be reproduced with alternate hyper-parameters, and which could not be reproduced at all, as well as provide insight as to why this might be the case. We then performed a large-scale benchmarking on four datasets with several thousands of experiments and 24,804 GPU hours of computation time. We present insights gained as to best practices, best configurations for each model, and where improvements could be made over previously published best configurations. Our results highlight that the combination of model architecture, training approach, loss function, and the explicit modeling of inverse relations is crucial for a model's performance and is not only determined by its architecture. We provide evidence that several architectures can obtain results competitive to the state of the art when configured carefully. We have made all code, experimental configurations, results, and analyses available at https://github.com/pykeen/pykeen and https://github.com/pykeen/benchmarking.
