An Exploratory Study Using Next-Generation Sequencing to Identify Prothrombotic Variants in Patients with Cerebral Vein Thrombosis.

Prothrombotic hereditary risk factors for cerebral vein thrombosis (CVT) are of clinical interest to better understand the underlying pathophysiology and stratify patients for the risk of recurrence. This study explores prothrombotic risk factors in CVT patients. An initial screening in patients of the outpatient clinic of the Department of Transfusion Medicine and Hemostaseology of the University Hospital Erlangen, Germany, revealed 183 patients with a history of CVT. An initial screening identified a number of common prothrombic risk factors, including Factor V Leiden (rs6025) and Prothrombin G20210A (rs1799963). All patients without relevant findings (58 individuals) were invited to participate in a subsequent genetic analysis of 55 relevant genes using next-generation sequencing (NGS). Three intron variants (ADAMTS13: rs28446901, FN1: rs56380797, rs35343655) were identified to occur with a significantly higher frequency in the CVT patient cohort compared to the general European population. Furthermore, the combined prevalence of at least two of four potentially prothrombic variants (FGA (rs6050), F13A1 (rs5985), ITGB3 (rs5918), and PROCR (rs867186)) was significantly higher in the CVT subjects. The possible impact of the identified variants on CVT is discussed.

TALKING TIME: A pilot randomized controlled trial investigating social support for informal caregivers via the telephone.

BACKGROUND: Caring for people with dementia at home requires considerable time, organization and commitment. Therefore, informal caregivers of people with dementia are often overburdened. This study examined the effects of the telephone-based Talking Time intervention, which is an approach used to strengthen the psychological health-related quality of life (HRQoL) and social support of informal caregivers of people with dementia living at home. METHODS: This study was a Medical Research Council framework phase two randomized controlled trial. The intervention consisted of a preliminary talk, information booklet, six structured telephone-based support group meetings and a structured written self-evaluation of each support group meeting. The control participants performed their usual individual self-organized care. After completing the data collection, the control group received the Talking Time intervention for fidelity reasons. The primary outcome was the self-rated psychological HRQoL of the informal caregivers, which was measured with the mental component summary of the General Health Survey Questionnaire Short Form 12 (SF-12). RESULTS: Thirty-eight informal caregivers and their relatives were included and allocated to the intervention or control groups (n = 19 each). After 3 months, the Talking Time intervention group demonstrated an increase in the self-rated psychological HRQoL scores, whereas the scores decreased in the control group. However, the standardized effect size of 1.65 (95% Confidence Interval, - 0.44 - 3.75) was not significant. Additionally, the secondary outcomes demonstrated no significant results. The differences between the groups in most outcomes were in the expected direction. No adverse effects were identified due to the intervention. CONCLUSIONS: The Talking Time intervention is feasible and shows nonsignificant promising results with regard to the self-rated psychological HRQoL. After further adjustment, the intervention needs to be evaluated in a full trial. TRIAL REGISTRATION: Clinical Trials: NCT02806583 , June 9, 2016 (retrospectively registered).

Empirical development of a typology on residential long-term care units in Germany - results of an exploratory multivariate data analysis.

BACKGROUND: Organizational health care research focuses on describing structures and processes in organizations and investigating their impact on the quality of health care. In the setting of residential long-term care, this effort includes the examination and description of structural differences among the organizations (e.g., nursing homes). The objective of the analysis is to develop an empirical typology of living units in nursing homes that differ in their structural characteristics. METHODS: Data from the DemenzMonitor Study were used. The DemenzMonitor is an observational study carried out in a convenience sample of 103 living units in 51 nursing homes spread over 11 German federal states. Characteristics of living units were measured by 19 variables related to staffing, work organization, building characteristics and meal preparation. Multiple correspondence analysis (MCA) and agglomerative hierarchical cluster analysis (AHC) are suitable to create a typology of living units. Both methods are multivariate and explorative. We present a comparison with a previous typology (created by a nonexplorative and nonmultivariate process) of the living units derived from the same data set. RESULTS: The MCA revealed differences among the living units, which are defined in particular by the size of the living unit (number of beds), the additional qualifications of the head nurse, the living concept and the presence of additional financing through a separate benefit agreement. We identified three types of living units; these clusters occur significantly with a certain combination of characteristics. In terms of content, the three clusters can be defined as: "house community", "dementia special care units" and "usual care". CONCLUSION: A typology is useful to gain a deeper understanding of the differences in the care structures of residential long-term care organizations. In addition, the study provides a practical recommendation on how to apply the results, enabling living units to be assigned to a certain type. The typology can be used as a reference for definitions.

Preferences for everyday living inventory (PELI): study protocol for piloting a culture-sensitive and setting-specific translated instrument in German care settings (PELI-D).

INTRODUCTION: Regardless of the healthcare setting, person-centred care and its implementation in caring for older people are a central issue for those who are responsible as professional caregivers and for those in need of care within the care process. Both aspects encompass the possibility of recognising personal preferences. To provide person-centred care, professional caregivers need to know about the individual preferences of the persons being cared for. Therefore, the PELI (an acronym for 'Preferences for Everyday Living Inventory') instrument was developed at the Polisher Research Institute (USA) for the systematic recording of individual preferences of older people in need of care. There is currently no comparable instrument available in the German language. METHODS: As part of the proposed project PELI-D, all versions of the original PELI instrument (nursing home version) were (1) culture-sensitively translated into German and will be (2) examined in a pilot study for their reliability, feasibility and practicability. For the project PELI-D, we worked together with our practice partners in Germany (Diaconia and Caritas in North Rhine-Westphalia) and collaborated with our partners in the USA who developed the PELI instrument. This study protocol focuses on the pilot study, which will be conducted by the German Center for Neurodegenerative Diseases (DZNE) (site Witten). ETHICS AND DISSEMINATION: This study was approved by the internal quality control committee of the DZNE (ID number: WI029 PELI-D) and by the ethics committee of the German Society of Nursing Science Duisburg branch office (ID number: 18-010). All personal information will be deidentified with a specific identification code and stored in a secured location apart from the rest of the study data. Only qualified and study-related staff will be allowed access to the data. The results of the study will be distributed nationally and internationally through peer-reviewed journals, conferences and journals for nursing care practice.
