Vom Instrument zum Konstrukt - standardisierte Messung gesundheitsbezogener Lebensqualität

Die Erhebung patientenberichteter Endpunkte ist in klinischer Forschung und Versorgung gleichermaßen relevant. Die gegenwärtig genutzten Instrumente zur Erhebung dieser Endpunkte sind allerdings wenig standardisiert, was die Vergleichbarkeit der erhobenen Daten einschränkt. Methoden der Item-Response Theory bieten die Möglichkeit, eine Standardisierung der Erhebung sowohl über Instrumente als auch über Sprachen zu erreichen. Im Rahmen dieser Habilitationsschrift wird zum einen die Entwicklung und Validierung einer konstruktbasierten, instrumentenunabhängigen Skala auf Basis eines probabilistischen Testmodells zur Erhebung von Depressivität beschrieben. Dabei zeigte sich, dass eine Messung der latenten Variable Depressivität mit verschiedenen Instrumenten möglich ist, Modellparameter in unabhängigen Stichproben angewendet werden können und Bayesianische Methoden genutzt werden können, um Modellparameter anhand neu erhobener Daten zu aktualisieren. Zum zweiten wird die Vergleichbarkeit von PROMIS Instrumenten über verschiedene Sprachen untersucht. Dabei zeigt sich, dass sowohl für die PROMIS Itembank zur Erhebung von Depressivität als auch im PROMIS Profile 29, das die zentralen Gesundheitsdomänen vereint, die Unterschiede in Itemparametern über Sprachen vernachlässigbar gering sind. Somit ist ein Vergleich der Testwerte über verschiedene Sprachversionen der getesteten Instrumente hinweg valide. Weitere Befunde bestätigen die Validität konstruktbasierter Skalen und auch die Ergebnisse zur Vergleichbarkeit über Sprachen wurden für andere Domänen beziehungsweise Sprachen berichtet. Eine Perspektive zur Weiterentwicklung der verwendeten Modelle sind Bayesianische IRT-Modelle, die klinisch irrelevante Unterschiede in den Itemparametern in verschiedenen Stichproben explizit modellieren können

Complementary and Integrative Medicine in Nursing Homes: Results of a Cross-Sectional Study in Residents and Caregivers

Objective: Some nursing homes for the elderly in Germany integrate complex complementary and integrative medicine interventions in the form of hydrotherapy, herbal and mind-body therapies, physical activities, and healthy eating, known as Kneipp therapy (KT), in care. This pilot study explored health- and work-related characteristics and acceptance of KT amongst residents and caregivers. Methods: Within a mixed-methods cross-sectional study in nursing homes who had integrated KT, we assessed work ability, psychosocial burden at work and health-related quality of life of caregivers, as well as a broad selection of health-related data of residents by questionnaires and assessments. Data were analyzed descriptively. Results: The data from 29 female caregivers (42.0 ± 11.7 years) and 64 residents (83.2 ± 8.1 years) were analyzed. Both caregivers (96%) and residents (89%) considered KT to be beneficial for health and well-being. Ninety percent of the caregivers indicated an improved relationship to residents since implementing KT. Caregivers showed a good work ability and quality of life. Residents attained remarkable ratings in social relation and affect-related aspects of quality of life. Conclusion: The results of this cross-sectional study indicate a high acceptance of integrating KT by residents and caregivers. The effectiveness and safety of KT should be explored in further comparative studies.Hintergrund: Einige Senioreneinrichtungen in Deutschland integrieren die Kombination aus Hydrotherapie, Phytotherapie, Ordnungstherapie, Bewegung und gesunder Ernährung als Kneipp-Therapie (KT) in die Pflege und Betreuung von Bewohnern. Diese Pilotstudie zielte darauf ab, gesundheits- und arbeitsbezogene Charakte­ristika und die Akzeptanz von KT bei Bewohnern und ­Mitarbeitern dieser Pflegeeinrichtungen zu untersuchen. Methoden: Im Rahmen einer Mixed-Methods-Querschnittsstudie in vier Senioreneinrichtungen, die KT integrierten, wurden unter anderem die Arbeitsfähigkeit, die psychosoziale Belastung am Arbeitsplatz und die gesundheitsbezogene Lebensqualität der Pflegekräfte sowie eine breite Auswahl an gesundheitsbezogenen Daten und die Lebensqualität der Bewohner durch Fragebögen erhoben. Alle Daten wurden deskriptiv analysiert. Ergebnisse: Es wurden die Daten von 29 Mitarbeiterinnen (42,0 ± 11,7 Jahre) und 64 Bewohnern (83,2 ± 8,1 Jahre) analysiert. Sowohl die Pflegekräfte (96%) als auch die Bewohner (89%) betrachteten KT als vorteilhaft für die Gesundheit und das Wohlbefinden. Ausserdem gaben 90% der Mitarbeiterinnen eine verbesserte Beziehung zu den Bewohnern seit der Einführung von KT an. Die Mitarbeiterinnen zeigten eine gute Arbeitsfähigkeit und Lebensqua­lität. Die Bewohner zeigten gute Bewertungen von Aspekten der Lebensqualität, die mit sozialer Beziehung und Affekt zusammenhängen. Fazit: Die Ergebnisse zeigen, dass KT in den untersuchten Senioreneinrichtungen von den Bewohnern und Betreuern gut angenommen wurde. Die spezifische Wirksamkeit und Sicherheit von KT sollten in weiteren vergleichenden Studien untersucht werden

results of a mixed methods pilot study

Background ‘Kneipp Therapy’ (KT) is a form of Complementary and Alternative Medicine (CAM) that includes a combination of hydrotherapy, herbal medicine, mind-body medicine, physical activities, and healthy eating. Since 2007, some nursing homes for older adults in Germany began to integrate CAM in the form of KT in care. The study investigated how KT is used in daily routine care and explored the health status of residents and caregivers involved in KT. Methods We performed a cross-sectional pilot study with a mixed methods approach that collected both quantitative and qualitative data in four German nursing homes in 2011. Assessments in the quantitative component included the Quality of Life in Dementia (QUALIDEM), the Short Form 12 Health Survey (SF-12), the Barthel-Index for residents and the Work Ability Index (WAI) and SF-12 for caregivers. The qualitative component addressed the residents’ and caregivers’ subjectively experienced changes after integration of KT. It was conceptualized as an ethnographic rapid appraisal by conducting participant observation and semi-structured interviews in two of the four nursing homes. Results The quantitative component included 64 residents (53 female, 83.2 ± 8.1 years (mean and SD)) and 29 caregivers (all female, 42.0 ± 11.7 years). Residents were multimorbid (8 ± 3 diagnoses), and activities of daily living were restricted (Barthel-Index 60.6 ± 24.4). The caregivers’ results indicated good work ability (WAI 37.4 ± 5.1), health related quality of life was superior to the German sample (SF-12 physical CSS 49.2 ± 8.0; mental CSS 54.1 ± 6.6). Among both caregivers and residents, 89% considered KT to be positive for well-being. The qualitative analysis showed that caregivers perceived emotional and functional benefits from more content and calmer residents, a larger variety in basic care practices, and a more self-determined scope of action. Residents reported gains in attention and caring, and recognition of their lay knowledge. Conclusion Residents showed typical characteristics of nursing home inhabitants. Caregivers demonstrated good work ability. Both reported to have benefits from KT. The results provide a good basis for future projects, e.g. controlled studies to evaluate the effects of CAM in nursing homes

The Rule of Law is Dead! Long Live the Rule of Law!

Polls show that a significant proportion of the public considers judges to be political. This result holds whether Americans are asked about Supreme Court justices, federal judges, state judges, or judges in general. At the same time, a large majority of the public also believes that judges are fair and impartial arbiters, and this belief also applies across the board. In this paper, I consider what this half-law-half-politics understanding of the courts means for judicial legitimacy and the public confidence on which that legitimacy rests. Drawing on the Legal Realists, and particularly on the work of Thurman Arnold, I argue against the notion that the contradictory views must be resolved in order for judicial legitimacy to remain intact. A rule of law built on contending legal and political beliefs is not necessarily fair or just. But it can be stable. At least in the context of law and courts, a house divided may stand

The NORMAN Suspect List Exchange (NORMAN-SLE): facilitating European and worldwide collaboration on suspect screening in high resolution mass spectrometry

Background: The NORMAN Association (https://www.norman-.network.com/) initiated the NORMAN Suspect List Exchange (NORMAN-SLE; https://www.norman-.network.com/nds/SLE/) in 2015, following the NORMAN collaborative trial on non-target screening of environmental water samples by mass spectrometry. Since then, this exchange of information on chemicals that are expected to occur in the environment, along with the accompanying expert knowledge and references, has become a valuable knowledge base for "suspect screening" lists. The NORMAN-SLE now serves as a FAIR (Findable, Accessible, Interoperable, Reusable) chemical information resource worldwide.Results: The NORMAN-SLE contains 99 separate suspect list collections (as of May 2022) from over 70 contributors around the world, totalling over 100,000 unique substances. The substance classes include per- and polyfluoroalkyl substances (PFAS), pharmaceuticals, pesticides, natural toxins, high production volume substances covered under the European REACH regulation (EC: 1272/2008), priority contaminants of emerging concern (CECs) and regulatory lists from NORMAN partners. Several lists focus on transformation products (TPs) and complex features detected in the environment with various levels of provenance and structural information. Each list is available for separate download. The merged, curated collection is also available as the NORMAN Substance Database (NORMAN SusDat). Both the NORMAN-SLE and NORMAN SusDat are integrated within the NORMAN Database System (NDS). The individual NORMAN-SLE lists receive digital object identifiers (DOIs) and traceable versioning via a Zenodo community (https:// zenodo.org/communities/norman-.sle), with a total of > 40,000 unique views, > 50,000 unique downloads and 40 citations (May 2022). NORMAN-SLE content is progressively integrated into large open chemical databases such as PubChem (https://pubchem.ncbi.nlm.nih.gov/) and the US EPA's CompTox Chemicals Dashboard (https://comptox. epa.gov/dashboard/), enabling further access to these lists, along with the additional functionality and calculated properties these resources offer. PubChem has also integrated significant annotation content from the NORMAN-SLE, including a classification browser (https://pubchem.ncbi.nlm.nih.gov/classification/#hid=101).Conclusions: The NORMAN-SLE offers a specialized service for hosting suspect screening lists of relevance for the environmental community in an open, FAIR manner that allows integration with other major chemical resources. These efforts foster the exchange of information between scientists and regulators, supporting the paradigm shift to the "one substance, one assessment" approach. New submissions are welcome via the contacts provided on the NORMAN-SLE website (https://www.norman-.network.com/nds/SLE/)

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
