Directional turnover towards larger-ranged plants over time and across habitats

Species turnover is ubiquitous. However, it remains unknown whether certain types of species are consistently gained or lost across different habitats. Here, we analysed the trajectories of 1827 plant species over time intervals of up to 78 years at 141 sites across mountain summits, forests, and lowland grasslands in Europe. We found, albeit with relatively small effect sizes, displacements of smaller- by larger-ranged species across habitats. Communities shifted in parallel towards more nutrient-demanding species, with species from nutrient-rich habitats having larger ranges. Because these species are typically strong competitors, declines of smaller-ranged species could reflect not only abiotic drivers of global change, but also biotic pressure from increased competition. The ubiquitous component of turnover based on species range size we found here may partially reconcile findings of no net loss in local diversity with global species loss, and link community-scale turnover to macroecological processes such as biotic homogenisation

Patient participation in multidisciplinary tumour conferences in breast cancer care (PINTU): a mixed-methods study protocol

Introduction A central instrument of multidisciplinary care is the multidisciplinary tumour conference (MTC). In MTCs, diagnosis and treatment of cancer patients are discussed, and therapy recommendations are worked out. As we found previously, patients participate in MTCs in some breast cancer centres in the state of North Rhine-Westphalia, Germany. However, studies on risks and benefits of patient participation have not provided substantiated findings. Therefore, the study's objective is to analyse differences between MTCs with and without patient participation. Methods and analysis This is an exploratory mixed-methods study. MTCs in six breast and gynaecological cancer centres in North Rhine-Westphalia, Germany, are examined. MTCs will be conducted with and without patient participation. First, interviews with providers concentrating on the feasibility of patient participation and quality of decision-making will be carried out, transcribed and analysed by means of content analysis. Second, videotaped or audiotaped participatory observations in MTCs will be executed. Video data or transcribed audio data from video and audio recordings will be coded using the established Observational Assessment Rating Scale for MTCs and analysed by comparing centres with and without patient participation. Third, all patients will fill out a questionnaire before and after MTC, including questions on psychosocial situation, decision-making and expectations before and experiences after MTC. The questionnaire data will be analysed by means of descriptive and multivariate statistics and pre-post-differences within and between groups. Ethics and dissemination Consultation and a positive vote from the ethics committee of the Medical Faculty of the University of Cologne have been obtained. For all collected data, relevant data protection regulations will be adhered to. All personal identifiers from patients and providers will be pseudonymised, except video recordings. Dissemination strategies include a discussion with patients and providers in workshops about topics such as feasibility, risks and benefits of patient participation in MTCs

The Diverse Forms of Lactose Intolerance and the Putative Linkage to Several Cancers

Lactase-phlorizin hydrolase (LPH) is a membrane glycoprotein and the only β-galactosidase of the brush border membrane of the intestinal epithelium. Besides active transcription, expression of the active LPH requires different maturation steps of the polypeptide through the secretory pathway, including N- and O-glycosylation, dimerization and proteolytic cleavage steps. The inability to digest lactose due to insufficient lactase activity results in gastrointestinal symptoms known as lactose intolerance. In this review, we will concentrate on the structural and functional features of LPH protein and summarize the cellular and molecular mechanism required for its maturation and trafficking. Then, different types of lactose intolerance are discussed, and the molecular aspects of lactase persistence/non-persistence phenotypes are investigated. Finally, we will review the literature focusing on the lactase persistence/non-persistence populations as a comparative model in order to determine the protective or adverse effects of milk and dairy foods on the incidence of colorectal, ovarian and prostate cancers

Overview of innovative technologies in liquid-liquid extraction regarding flexibility

As a result of increasing market volatility and product diversification the technology requirements will change in the future. Flexibility needs to be increased, enabling a large operating window while maintaining intensive mass and energy transfer and resource-efficiency. A promising approach is using innovative small-scale technologies. To assess flexibility, the technologies must be characterized in a wide range of operating parameters and physical properties. Therefore, research work on innovative technologies for liquid-liquid extraction is presented

Measurement of the Chair Rise Performance of Older People Based on Force Plates and IMUs

An early detection of functional decline with age is important to start interventions at an early state and to prolong the functional fitness. In order to assure such an early detection, functional assessments must be conducted on a frequent and regular basis. Since the five time chair rise test (5CRT) is a well-established test in the geriatric field, this test should be supported by technology. We introduce an approach that automatically detects the execution of the chair rise test via an inertial sensor integrated into a belt. The system’s suitability was evaluated via 20 subjects aged 72–89 years (78.2 ± 4.6 years) and was measured by a stopwatch, the inertial measurement unit (IMU), a Kinect® camera and a force plate. A Multilayer Perceptrons-based classifier detects transitions in the IMU data with an F1-Score of around 94.8%. Valid executions of the 5CRT are detected based on the correct occurrence of sequential movements via a rule-based model. The results of the automatically calculated test durations are in good agreement with the stopwatch measurements (correlation coefficient r = 0.93 (p < 0.001)). The analysis of the duration of single test cycles indicates a beginning fatigue at the end of the test. The comparison of the movement pattern within one person shows similar movement patterns, which differ only slightly in form and duration, whereby different subjects indicate variations regarding their performance strategies

Towards an Automated Unsupervised Mobility Assessment for Older People Based on Inertial TUG Measurements

One of the most common assessments for the mobility of older people is the Timed Up and Go test (TUG). Due to its sensitivity regarding the indication of Parkinson’s disease (PD) or increased fall risk in elderly people, this assessment test becomes increasingly relevant, should be automated and should become applicable for unsupervised self-assessments to enable regular examinations of the functional status. With Inertial Measurement Units (IMU) being well suited for automated analyses, we evaluate an IMU-based analysis-system, which automatically detects the TUG execution via machine learning and calculates the test duration. as well as the duration of its single components. The complete TUG was classified with an accuracy of 96% via a rule-based model in a study with 157 participants aged over 70 years. A comparison between the TUG durations determined by IMU and criterion standard measurements (stopwatch and automated/ambient TUG (aTUG) system) showed significant correlations of 0.97 and 0.99, respectively. The classification of the instrumented TUG (iTUG)-components achieved accuracies over 96%, as well. Additionally, the system’s suitability for self-assessments was investigated within a semi-unsupervised situation where a similar movement sequence to the TUG was executed. This preliminary analysis confirmed that the self-selected speed correlates moderately with the speed in the test situation, but differed significantly from each other

Is patient participation in multidisciplinary tumour conferences associated with their information needs? A multicentre prospective observational study

Objectives To determine the association between participation of patients with breast cancer and patients with gynaecological cancer in their own multidisciplinary tumour conference (MTC) and their information needs with regard to their disease and treatment options. Methods This is a prospective observational study that took place at six breast cancer and gynaecological cancer centres in North Rhine-Westphalia, Germany. Patient inclusion criteria included a minimum age of 18 years and at least one diagnosis of breast cancer or gynaecological cancer. Three surveys were administered. T0 (shortly before MTC), T1 (directly after MTC) and T2 (4 weeks after MTC). Patient information needs were measured using two three-item subscales of the Cancer Patients Information Needs scale. Analysis of change was done by one-way repeated measures analysis of variance (ANOVA). To control for sampling bias, a further one-way repeated measures analysis of covariance (ANCOVA) included a propensity score as a covariate. Results Data from 81 patients in the participation group and 120 patients in the non-participation group were analysed. The patient groups did not differ in their levels of information needs at T0 or T2. From T0 to T2, information needs increased statistically significantly in both groups with regard to both disease-related information (eta(2)=0.354) and treatment-related information (eta(2)=0.250). The increase in both types of information needs lost its statistical significance when the propensity score was included as a covariate. Neither ANOVA nor ANCOVA revealed a statistically significant association between patients' participation in the MTC and their self-reported information needs. Conclusion and clinical implications As concerns patients' information needs, findings do not support a general recommendation for or against the participation of patients in their MTCs. Future research should focus on the different ways of patients' participation in their MTCs facilitated at different cancer centres. Further research should also aim to establish which patient and disease characteristics predispose patients to benefit from participating in their MTCs

Health literacy and patient participation in multidisciplinary tumor conferences in breast cancer care: a multilevel modeling approach

Background: Decisions made in multidisciplinary tumor conferences (MTC) that consider patient preferences result in better patient outcomes. Furthermore, it has been shown that in some breast cancer centers in Germany, patients participate in MTCs and that participation is associated with sociodemographic and breast cancer center-related factors. Health literacy (HL) has been shown to be predictive for individual health behavior and is an important prerequisite for patient participation in healthcare. However, so far nothing is known about the association between HL and MTC patient participation. To close this gap in research, we analyzed which patient characteristics affect participation in MTCs and whether participation varies between breast cancer centers. Methods: In a prospective, multicenter cohort study, newly diagnosed breast cancer patients were surveyed directly after surgery (T1) as well as 10 weeks (T2) and 40 weeks (T3) after surgery. After descriptive analysis, t-tests were conducted, correlations for independent variables were run, and logistic multilevel regression analysis was applied to estimate the association between patient participation in MTCs at T1 and HL (HLS-EU-Q16 [1]), sociodemographic and disease-related characteristics (n = 863 patients) and the variation between breast cancer centers (n = 43 centers). Results: Descriptive results show that 6.8% of breast cancer patients took part in a MTC. The logistic multilevel regression model revealed that patients with an inadequately HL are less likely to participate in MTCs (OR = 0.31, 95%-CI = 0.1-0.9, Pseudo-R-2 = 0.06), and participation is dependent on the breast cancer center (ICC = 0.161). Conclusions: These findings are the first to show significant differences in HL and patient participation in MTCs in a large sample of breast cancer patients. In future research on patient participation in MTCs and HL, questions concerning the organization, communication and decision-making in MTCs with and without patient participation have to be addressed, and patient and provider perspectives must be equally considered

How do breast cancer patients experience multidisciplinary tumor conferences? - A description from the patient perspective

Objectives: Aim of this study was to investigate the experiences of breast cancer patients who participated in multidisciplinary tumor conferences (MTCs). Study design: Data from two consecutive years of an annual postal survey of patients with primary breast cancer were combined. Data was collected between February and July 2015 (response rate 72%) and 2016 (response rate 73%) from N= 8893 patients (ICD-10 C50) after hospital discharge from 86 breast cancer center hospitals in North Rhine-Westphalia, Germany. The study used a mixed-methods design. Standardized quantitative survey questions were analyzed descriptively and an open-ended question was analyzed using qualitative content analysis. Results: Around 9% of the patients were invited to participate in a multidisciplinary tumor conference (MTC) and 49% of the invited patients reported actual participation in a MTC. Approximately 87% of those patients did not regret their participation in the MTC. The qualitative analysis from the open-ended question indicated that MTC participation was perceived by patients as being both supportive and informative (n = 109 expressions). However, some patients reported difficult experiences and emotional reactions during and after participation (n =37 expressions). Altogether, the patients' perception was divided into positive and negative, cognitive and emotional experiences following participation in a MTC. Conclusion: The perception of the MTCs varies between the participating patients. Further research on advantages and disadvantages for patients and particularly on the feasibility from the provider's perspective is necessary. (C) 2019 The Authors. Published by Elsevier Ltd
