The impact of automated, constant incomplete milking on energy balance, udder health, and subsequent performance in early lactation of dairy cows

Incomplete milking (IM) is one way of mitigating the negative energy balance (NEB) that is characteristic for early lactation and may increase the risk for disease. Our objectives were to test the effects of IM in early lactation on energy balance (EB), metabolic status, udder health, and subsequent performance. To facilitate the practical application, an automated system was used to remove the milking clusters once a predefined amount of milk is withdrawn. Forty-six Holstein cows were equally allocated to either the treatment (TRT, starting on 8 d in milk) or the control group (CON; conventional cluster removal at milk flow rate <0.3 kg/min). Milk removal in the TRT group was limited to the individual cow's milk yield 1 d before IM started and held constant for 14 d. Thereafter, all cows were conventionally milked and records related to EB, performance, and udder health were continued up to 15 wk of lactation. During the 14 d of IM, on average 11.1% less milk was obtained from the TRT cows than from the CON cows. Thereafter, milk yield increased in the TRT group, eliminating the group difference throughout the remaining observation period until wk 15 of lactation. The TRT cows tended to have less dry matter intake and also water intake than the CON cows. The extent of the NEB and the circulating concentrations of fatty acids, β-hydroxybutyrate, insulin-like growth factor-1, and leptin mostly did not differ between the groups. The IM did not affect body condition. Udder health was maintained over the entire observation period in all cows. Our results demonstrate the applicability of the automated cluster removal for limiting milk withdrawal to a defined amount in early lactation. However, it remains to be determined whether the absent effect on energy metabolism was due to the relatively stable energy status of the cows or to the relatively mild IM setting used herein.

Prescribing of valproate and oral antiepileptics for women of childbearing age and during pregnancy in Germany between 2010 and 2020

PURPOSE

To examine prescriptions of valproate and oral antiepileptic drugs (OAED) in Germany irrespective of the indication in women in general and particularly in women of childbearing age (13-49 years) and during pregnancy between 2010 and 2020, that is, before, during and after the implementation of the EU risk minimization measures (RMMs).

METHODS

Analysis of claims data.

STUDY POPULATION

all women continuously insured with the AOK health insurance fund in the respective observation year (2010-2020) and the previous year. OAED were identified by ATC code N03. Period of pregnancy was calculated based on birth information in claims data.

MAIN OUTCOMES MEASURES

(i) prevalent use of valproate/OAED: number of women with at least one prescription of valproate/OAED per year divided by all women of the study population (rate per 1000 women); (ii) percentage of OAED recipients with at least one valproate prescription during pregnancy (13-49 years) in the respective observation year.

RESULTS

Prevalence rate/1000 women for valproate use decreased by -31.33% across all age groups (2010-2014: -7.48%; 2014-2018: -16.47%; 2018-2020: -11,17%) with a strong reduction in women 13-49 years between 2014 and 2018 (-28.74%). The rate for OAED across all age groups rose from 33.43/1000 women in 2010 to 41.03/1000 (+22,73%). Valproate use during pregnancy of women with OAED declined from 1.29% in 2010 to 0.59% in 2020 (-54,26%) (2010-2014: -5.14%; 2014-2018: -42.31%; 2018-2020: -16.69%).

CONCLUSION

Even if, due to the descriptive nature of the study, no causal relationship can be postulated between the RMMs and the strong decrease in valproate prescriptions, our results are compatible with the hypothesis that the measures have improved drug therapy safety.

Claims data analysis of the health care utilization for patients with coronary heart disease and mental comorbidity

OBJECTIVE

Mental disorders (MD) are a common comorbidity in patients with coronary heart disease (CHD) and have a significant impact on morbidity and mortality. The aim of this study was to determine to what extent mental disorders are diagnosed as comorbidity in patients with CHD and whether adequate therapeutic measures are taken.

METHODS

Claims data from 4435 Cologne citizens with diagnosed CHD and a hospital stay due to CHD in 2015 were examined through a longitudinal analysis. The data were analyzed descriptively with regard to mental disorders, investigating diagnostic examinations performed, prescriptions for psychotropic drugs, and utilization of psychotherapy. We differentiated between pre-existing MD, existing in the year before the CHD-related hospital stay, and incident MD with new onset during or within six months after hospitalization.

RESULTS

Psychodiagnostic examinations for mental disorders occurred very rarely during cardiological hospitalization (0.04%) and psychiatric/psychosomatic consultation sessions rarely (5%). The longitudinal analysis showed a high rate of pre-existing MDs (56%, n = 2490) and a new diagnosis of mental disorders in 7% (n = 302) of the patients. Within one year after inpatient treatment for CHD, psychotropic medication was prescribed in 64-67% of patients with newly diagnosed affective or neurotic, adjustment/somatoform disorder and 10-13% received outpatient psychotherapy.

CONCLUSION

The results indicate low rates of inpatient diagnostic examinations and low rates of adequate treatment of mental disorders in patients from Cologne with CHD and new onset mental disorders. The rate of prescriptions of psychopharmacotherapy after hospitalization due to CHD exceeds that of the utilization of outpatient psychotherapy.

[Development and Internal Validation of Case Definitions for Prevalence Estimation of Microvascular Complications of Diabetes in Routine Data]

BACKGROUND

Surveillance of diabetes requires up-to-date information on the prevalence of diabetes and its complications over time. For this purpose, statutory health insurance (SHI) data is being increasingly used, as the data is available in a timely fashion and case numbers enable detailed estimates also of diabetes complications. The aim of the present study was the development and internal validation of case definitions for the prevalence estimation of diabetic retinopathy (DRP), diabetic polyneuropathy (DPN) and diabetic foot syndrome (DFS).

METHODS

Persons with diabetes differentiated by type 1, type 2, and other diabetes in an age- and sex-stratified sample of persons insured by Barmer SHI in 2018 (n=72,744) comprised the study popuation. Based on the central ICD codes for microvascular complications (DRP: H36.0; DPN: G63.2; DFS: E1X.74/.75), case definitions were developed including additional ICD codes for complications without direct diabetes reference. Subsequently, the case definitions were internally validated. For the validation, coding in the inpatient setting (m1S) or repeatedly in the outpatient setting (m2Q) as well as coding of specific procedures (EBM, OPS) and drug prescriptions or by relevant specialists were considered. Additionally, we analysed the documentation of the diagnoses in the previous years.

RESULTS

In 2018, the prevalence of the central ICD codes was 8.4% for DRP (H36.0), 18.9% for DPN (G63.2) and 13.4% for DFS (E1X.74/.75). After inclusion of additional ICD codes in the case definition, prevalence increased significantly for DRP (9.6%) and DPN (20.7%), and barely for DFS (13.5%). Internal validation confirmed the majority of diagnoses (DRP: 96.7%; DPN: 96.5% DFS: 95.8%) and m2Q represented the most relevant criterion. When up to four previous years were considered, prevalences were up to 30% higher for DPN and DFS and up to 64% higher for DRP.

CONCLUSION

The inclusion of additional ICD codes in the case definition of microvascular complications of diabetes appears meaningful, as this increases the sensitivity of the prevalence estimate. Internal validation suggests that the documented diagnoses are plausible. However, not all diagnoses are documented annually, leading to an underestimation of the prevalence using a cross-sectional study design of one year.

Effects of a Primary Care-Based Intervention on the Identification and Management of Patients with Coronary Heart Disease and Mental or Cognitive Comorbidity-A Study Protocol

Mental and cognitive disorders (MCD) negatively affect the incidence and prognosis of coronary heart disease (CHD). Medical guidelines recommend the appropriate management of comorbid MCD in patients with CHD, yet there is evidence that the implementation in primary care is not always adequate. We present the protocol for a pilot study that aims to develop a minimally invasive intervention and evaluate its feasibility in the primary care setting to improve the identification and management of comorbid MCD in patients with CHD. The study consists of two consecutive parts and will be carried out in Cologne, Germany. Part 1 comprises the development and tailoring of the intervention, which is guided by qualitative interviews with primary care physicians (PCPs, n = 10), patients with CHD and MCD and patient representatives (n = 10). Part II focuses on the implementation and evaluation of the intervention in n = 10 PCP offices. Changes in PCP behaviour will be analysed by comparing routine data in the practice management system six months before and six months after study participation. In addition, we will explore the influence of organisational characteristics and perform a socio-economic impact assessment. The outcomes of this mixed-method study will inform the feasibility of a PCP-based intervention to improve quality of care in patients with CHD and comorbid MCD.

Introduction: Care integration needs to take place on different levels, including that of infrastructure and especially data infrastructure. Only integrated data allow for policy making, care planning, research, and evaluation that spans across different sectors of care and support. Methods: In the course of an EU-funded reform initiative on integrated care, the Estonian government and various agencies have developed a concept for an integrated data centre, bringing together information from social, medical, and vocational support services. The concept was developed in co-production with many stakeholders. A test data set from all covered sectors, including the pseudonymised data of 17,945 citizens of an Estonian municipality, was created and analysed as a proof-of-concept exercise. Results: The co-production approach resulted in a set of requirements and use cases as well as a specification of premises, processes, and data flows for the data centre. The analysis of the test dataset showed the principal feasibility of the dataset for the intended purposes. Conclusion: The concept development phase showed that an integrated data centre for Estonia is feasible per se and helped to specify concrete actions required for its realisation. Strategic and financial decisions from the Estonian Reform Steering Committee are now needed to create the data centre.

[Research Data Center on Health - Vision for Further Development from the Research Perspective]

The German research data center for health will provide claims data of statutory health insurances. The data center was set up at the medical regulatory body BfArM pursuant to the German data transparency regulation (DaTraV). The data provided by the center will cover about 90% of the German population, supporting research on healthcare issues, including questions of care supply, demand and the (mis-)match of both. These data support the development of recommendations for evidence-based healthcare. The legal framework for the center (including §§ 303a-f of Book V of the Social Security Code and two subsequent ordinances) leaves a considerable degree of freedom when it comes to organisational and procedural aspects of the center's operation. The present paper addresses these degrees of freedom. From the point of view of researchers, ten statements show the potential of the data center and provide ideas for its further and sustainable development.

How is leadership behavior associated with organization-related variables? Translation and psychometric evaluation of the implementation leadership scale in German primary healthcare

Background

The Implementation Leadership Scale (ILS) was developed to assess leadership behavior with regard to being proactive, knowledgeable, supportive, or perseverant in implementing evidence-based practices (EBPs). As part of a study on the implementation of a digitally supported polypharmacy management application in primary care, the original ILS was translated and validated for use in the German language.

Rationale

This study aimed to translate the original ILS into German and evaluate its psychometric properties.

Methods

The validation sample consisted of 198 primary care physicians in a cluster-randomized controlled trial in which the intervention group implemented a digitally supported clinical decision support system for polypharmacy management. The ILS was assessed using a 12-item scale. The study included a process evaluation with two evaluation waves between 2019 and 2021. The ILS was used within this process evaluation study to assess the leadership support with regard to the implementation of the polypharmacy management. The ILS was translated in a multi-step process, including pre-testing of the instrument and triple, back-and-forth translation of the instrument. We tested the reliability (Cronbach’s alpha) and validity (construct and criterion-related validity) of the scale.

Results

The four-dimensional structure of the instrument was confirmed (comparative fit index = .97; root mean square error of approximation = .06). Convergent validity was demonstrated by correlations with organizational innovation climate, social capital, and workload, which was consistent with the proposed hypothesis. Criterion-related validity of the ILS was demonstrated by predicting the organizational readiness for change scores using structural equation modeling. The reliability of the scale was good (α = .875).

Conclusion

The German version of the ILS created in this study is a reliable and valid measure. The original four-dimensional structure of the ILS was confirmed in a primary care setting. Further psychometric testing is needed to establish the validity and reliability of the ILS and to transfer it to other health care settings. It is a useful tool for identifying the areas for implementation leadership development. Further research is needed on how, why, and when distinct types of leadership behaviors have different effects on healthcare organizations in implementation processes.

Effectiveness of the application of an electronic medication management support system in patients with polypharmacy in general practice: a study protocol of cluster-randomised controlled trial (AdAM)

INTRODUCTION

Clinically complex patients often require multiple medications. Polypharmacy is associated with inappropriate prescriptions, which may lead to negative outcomes. Few effective tools are available to help physicians optimise patient medication. This study assesses whether an electronic medication management support system (eMMa) reduces hospitalisation and mortality and improves prescription quality/safety in patients with polypharmacy.

METHODS AND ANALYSIS

Planned design: pragmatic, parallel cluster-randomised controlled trial; general practices as randomisation unit; patients as analysis unit. As practice recruitment was poor, we included additional data to our primary endpoint analysis for practices and quarters from October 2017 to March 2021. Since randomisation was performed in waves, final study design corresponds to a stepped-wedge design with open cohort and step-length of one quarter.

SCOPE

general practices, Westphalia-Lippe (Germany), caring for BARMER health fund-covered patients.

POPULATION

patients (≥18 years) with polypharmacy (≥5 prescriptions).

SAMPLE SIZE

initially, 32 patients from each of 539 practices were required for each study arm (17 200 patients/arm), but only 688 practices were randomised after 2 years of recruitment. Design change ensures that 80% power is nonetheless achieved.

INTERVENTION

complex intervention eMMa.

FOLLOW-UP

at least five quarters/cluster (practice). recruitment: practices recruited/randomised at different times; after follow-up, control group practices may access eMMa.

OUTCOMES

primary endpoint is all-cause mortality and hospitalisation; secondary endpoints are number of potentially inappropriate medications, cause-specific hospitalisation preceded by high-risk prescribing and medication underuse.

STATISTICAL ANALYSIS

primary and secondary outcomes are measured quarterly at patient level. A generalised linear mixed-effect model and repeated patient measurements are used to consider patient clusters within practices. Time and intervention group are considered fixed factors; variation between practices and patients is fitted as random effects. Intention-to-treat principle is used to analyse primary and key secondary endpoints.

ETHICS AND DISSEMINATION

Trial approved by Ethics Commission of North-Rhine Medical Association. Results will be disseminated through workshops, peer-reviewed publications, local and international conferences.

Ischemic stroke on hormonal contraceptives: Characteristics, mechanisms and outcome

Introduction

Systemic contraceptives increase the risk of ischemic stroke but little is known about the characteristics, mechanisms and long-term outcome post stroke of patients on hormonal contraception. We sought to To assess characteristics and outcome of acute ischemic stroke (AIS) in young women using systemic hormonal contraceptives (SHC) and compare them to strokes in non-contraceptive users.

Patients and methods

Using the Acute STroke Registry and Analysis of Lausanne (ASTRAL), we analyzed demographics, risk factors, clinical, radiological and treatment data of consecutive female patients of <50 years between 2003 to 2015. We compared groups with and without SHC in a logistic regression analysis.

Results

Of the 179 female patients of <50 years during the observation period, 57 (39.6%) used SHC, 71.9% of whom, a combined oral contraceptive pill. On logistic regression contraceptive users were significantly younger but had comparable stroke severity. They had less migraine with aura and tobacco use, and more hyperlipidaemia. Also, contraceptive users had significantly less intra and extracranial stenosis and occlusion on arterial imaging, but more focal hypoperfusion on CT-perfusion. Undetermined mechanism of stroke was more frequent with SHC users, whereas rare mechanisms were more frequent in non-users. The contraceptive user group had a more favourable adjusted 12-month outcome with significantly fewer ischemic recurrences after stopping systemic contraception in all.

Conclusion

Contraceptive users with ischemic strokes are younger and have lesser tobacco use and migraine with aura and more hyperlipidemia. Their stroke mechanism is more often undetermined using a standardised work-up, and their adjusted long-term outcome is more favourable with less stroke recurrence.

Last Year of Life Study-Cologne (LYOL-C) (Part II): study protocol of a prospective interventional mixed-methods study in acute hospitals to analyse the implementation of a trigger question and patient question prompt sheets to optimise patient-centred care

INTRODUCTION

The Last Year of Life Study-Cologne Part I (LYOL-C I) has identified general hospital units as the most important checkpoints for transitions in the last year of life of patients. Yet, satisfaction with hospitals, as reported by bereaved relatives, is the lowest of all health service providers. Thus, the LYOL-C Part II (LYOL-C II) focuses on optimising patient-centred care in acute hospitals for patients identified to be in their last year of life. LYOL-C II aims to test an intervention for hospitals by using a two-sided (healthcare professionals (HCPs) and patients) trigger question-based intervention to 'shake' the system in a minimally invasive manner.

METHODS AND ANALYSIS

Prospective interventional mixed-methods study following a two-phase approach: phase I, individual interviews with HCPs and patient representatives to design the intervention to maximise ease of implementation and phase II, exploratory study with two arms and a prepost design with patients in their last year of life. The intervention will consist of the Surprise Question and the German version of the Supportive and Palliative Care Indicators Tool (SPICT-DE) for HCPs to identify patients and provide patient-centred care, plus question prompt sheets for patients, encouraging them to initiate discussions with their HCPs. Data on transitions, changes in therapy, quality of care, palliative care integration and death of patients will be analysed. Furthermore, a staff survey (pre/post) and guided interviews with staff, patients and relatives (post) will be conducted. Finally, a formative socioeconomic impact assessment to provide evidence regarding the sustainability of the intervention will be performed.

ETHICS AND DISSEMINATION

The study was approved by the Ethics Committee of the Faculty of Medicine of the University of Cologne (#20-1431). Results will be published in peer-reviewed journals and presented at national and international conferences.

[The use of data for public health and healthcare-a shared goal of the EU member states]

Die Gesundheit der Bevölkerung – im Sinne von Prävention und Versorgung – braucht gute Daten. Daten unterstützen die Entscheidungsfindung auf der Systemebene ebenso wie konkrete Maßnahmen auf der Individualebene. Daten sind außerdem Voraussetzung für Forschung und die Entwicklung von Innovation. Gleichzeitig sind Daten Mangelware: Sie liegen nur in Ausschnitten oder für ganze Systemteile überhaupt nicht vor, sie decken Sachverhalte nur approximativ ab oder sind in Formaten gebunden, die eine automatisierte (bzw. skalierbare) Verarbeitung erschweren bis unmöglich machen. Zudem sind gerade Gesundheitsdaten höchst sensibel und entsprechend geschützt, was ihre Verwertung noch herausfordernder macht.

Mit diesen Herausforderungen steht Deutschland nicht allein da, sie finden sich in ähnlicher Form in allen anderen Mitgliedsstaaten der Europäischen Union (EU). Das Potenzial einer gemeinsamen Problemdefinition sowie der gemeinsamen Entwicklung von Lösungen wird in Deutschland bisher aber nur wenig genutzt. Der Artikel gibt einen Einblick in verschiedene EU-Initiativen rund um das Thema Gesundheitsdaten. Im Vordergrund steht dabei die Frage, wie deutsche Akteur:innen Zugang zu diesen Initiativen bekommen können, um so einerseits vom Wissen und den Erfahrungen in den Nachbarländern zu profitieren, aber auch um eigenes Wissen in diesen Kreis zurückgeben zu können.

Good Practice Data Linkage (GPD): A Translation of the German Version

The data linkage of different data sources for research purposes is being increasingly used in recent years. However, generally accepted methodological guidance is missing. The aim of this article is to provide methodological guidelines and recommendations for research projects that have been consented to across different German research societies. Another aim is to endow readers with a checklist for the critical appraisal of research proposals and articles. This Good Practice Data Linkage (GPD) was already published in German in 2019, but the aspects mentioned can easily be transferred to an international context, especially for other European Union (EU) member states. Therefore, it is now also published in English. Since 2016, an expert panel of members of different German scientific societies have worked together and developed seven guidelines with a total of 27 practical recommendations. These recommendations include (1) the research objectives, research questions, data sources, and resources; (2) the data infrastructure and data flow; (3) data protection; (4) ethics; (5) the key variables and linkage methods; (6) data validation/quality assurance; and (7) the long-term use of data for questions still to be determined. The authors provide a rationale for each recommendation. Future revisions will include new developments in science and updates of data privacy regulations.

BeyondSilos, a Telehealth-Enhanced Integrated Care Model in the Domiciliary Setting for Older Patients: Observational Prospective Cohort Study for Effectiveness and Cost-Effectiveness Assessments

BACKGROUND

Information and communication technology may provide domiciliary care programs with continuity of care. However, evidence about the effectiveness and cost-effectiveness of information and communication technology in the context of integrated care models is relatively scarce.

OBJECTIVE

The objective of our study was to provide evidence on the clinical effectiveness and cost-effectiveness of the BeyondSilos project for patients enrolled in the Badalona city pilot site in Spain.

METHODS

A quasi-experimental study was used to assess the cost-effectiveness of information and communication technology-enhanced integration of health and social care, including the third sector (intervention), compared to basic health and social care coordination (comparator). The study was conducted in Badalona between 2015 and 2016. Participants were followed for 8 months.

RESULTS

The study included 198 patients: 98 in the intervention group and 100 in the comparator group. The mean Barthel index remained unchanged in the intervention group (mean change 0.14, 95% CI -4.51 to 4.78; P=.95) but decreased in the comparator group (mean change -3.23, 95% CI -5.34 to -1.11; P=.003). Instrumental Activities of Daily Living significantly decreased in both groups: mean changes of -0.23 (95% CI -0.44 to -0.02; P=.03) and -0.33 (95% CI -0.46 to -0.20; P<.001) in the intervention and comparator groups, respectively. No differences were found in the Geriatric Depression Scale (intervention: mean change 0.28, 95% CI -0.44 to 1.01, P=.44; comparator: mean change -0.29, 95% CI -0.59 to 0.01, P=.06). The intervention showed cost-effectiveness (incremental cost-effectiveness ratio €6505.52, approximately US $7582).

CONCLUSIONS

The information and communication technology-enhanced integrated domiciliary care program was cost-effective. The beneficial effects of this approach strongly rely upon the commitment of the professional staff involved.

[Security and user acceptance of an intelligent home emergency call system for older people living at home with limited daily living skills and receiving home care]

BACKGROUND

Technically based support measures are becoming increasingly more important in an aging society. Such support measures can provide a self-determined life in familiar surroundings despite the need for care. An example for such a support measure is an intelligent home emergency call system (iHNR system), which automatically detects critical situations (e.g. falling down), transmits this information to an emergency call center and therefore initiates assistance faster.

OBJECTIVE

The aim of this uncontrolled, two center observational study was to evaluate the security and acceptance of an iHNR system used by older people receiving home care.

MATERIAL AND METHODS

The study was carried out based on 51 subjects with at least a 6-month observation period using the iHNR system. The iHNR system was installed in all homes of the participants. Interviews about acceptance, perceived and objective security, impact on independence and usability of the new iHNR system were conducted. Analysis was performed with particular respect to depression, quality of life, frailty and self-estimated need for assistance.

RESULTS

A total of 39 complete records were collected and evaluated. The participants represented a vulnerable group of people with rather depressive moods, negative quality of life and a high level of frailty without significant changes over the observation period. Positive results were found regarding subjective and objective security and acceptance as well as ease of operation of the iHNR system. The fear of falling was only marginally influenced.

CONCLUSION

Acceptance regarding the new iHNR system was high. The system provoked a stronger sense of security while at the same time leading to a reduced sense of control. The system seems to be able to detect critical events and can automatically and quickly alert the necessary help services. Therefore, people in need of care can remain longer in their own homes.

[Date of Service Provision and Date of Payment in Claims Data: Dealing with Time Differences]

AIM

The paper quantifies discrepancies between date of payment and date of service provision when doing analyses in relation to date of death and also in relation to the end of a calendar year. In analyses of this type, time differences between service provision and payment can lead to both under- and overestimation of service use. We aim to capture these phenomena in claims data from different sectors (primary care, medication prescription, prescription of remedies and medical aids, hospital care).

METHOD

We have used pre-structured claims data from a scientific data warehouse of a large German statutory health insurance covering people that died in 2016. We investigated the discrepancies in time between date of service provision and date of payment for different outpatient and inpatient services based on data from 2015 to 2017. An exact date (dd/mm/yyyy) was only available for data covering prescriptions of remedies and medical aids. Data covering medication prescriptions were only exact to the month of payment (mm/yyyy), whereas data covering outpatient physician care were only exact to the quarter of payment (q/yyyy).

RESULTS

For both outpatient physician care and hospital care, less than 1% had a payment date after the date of death. The share is considerably higher (28-31%) for prescriptions of remedies and medical aids. The majority of payments occurred within 3 months after death (93% for prescriptions of remedies and medical aids, 67% for primary care services). Less than 1% of outpatient physician care and about 18% of remedies had been paid after the end of the calender year 2015. Here too, the majority of payments were made within the first 3 months of 2016 (100% of prescriptions of remedies and medical aids, 65% of primary care services).

CONCLUSIONS

Discrepancies in time between date of service provision and date of payment pose a challenge and are a potential source of under-/overestimation of health service utilization when doing analyses in relation to date of death or the end of a calendar year. This needs to be taken into account when requesting the data, but also in preparing and analysing them. The primary recommendation is to ensure that services with a payment date after death are included explicitly.

PEN-13: A New Generic 13-Item Questionnaire for Measuring Patient Enablement (German Version)

Background: The purpose of our study was to develop and psychometrically test a German-language survey instrument that measures patient enablement generically and in greater detail than previous instruments. Methods: A multidisciplinary team developed 13 items to capture individual aspects of patient enablement (PEN-13). A pre-test with 26 subjects was followed by a random sample survey of N = 1168 subjects. An exploratory factor analysis was conducted in a random split-half sample of the data to explore PEN-13's factor structure; a confirmatory factor analysis was conducted in the validation sample. The internal consistency of the factors was evaluated using Cronbach's alpha, PEN-13's construct validity was checked by means of additional hypothesis testing. Results: The two factors self-management and patient-practitioner interaction, detected in the exploratory analysis, were confirmed with a few modifications in the confirmatory factor analysis, with the comparative fit index (CFI) amounting to 0.903. The Cronbach's alpha values of those two factors amounted to α = 0.90 and α = 0.82, respectively. The correlations of the PEN-13 score with the 'general self-efficacy' and 'health literacy' (HLS-EU-Q16) scores further confirmed its construct validity; the respective correlation coefficients amounted to 0.57 and 0.60. Conclusion: The German version of the survey instrument Patient Enablement Scale-13 items (PEN-13) shows acceptable psychometric properties. Practical implications: PEN-13 seems particularly suitable for health services research purposes. We recommend checking the results in another sample as well as evaluating its responsiveness to enablement-enhancing interventions.

[Good Practice Data Linkage]

Individual data linkage of different data sources for research purposes is being increasingly used in Germany in recent years. However, generally accepted methodological guidance is missing. The aim of this article is to define such methodological standards for research projects. Another aim is to provide readers with a checklist for critical appraisal of research proposals and articles. Since 2016, an expert panel of members of different German scientific societies have worked together and developed 7 guidelines with a total of 27 practical recommendations. These recommendations include (1) research aims, questions, data sources and resources, (2) infrastructure and data flow, (3) data privacy, (4) ethics, (5) key variables and type of linkage, (6) data validation/quality assurance and (7) long-term use for future research questions. The authors provide a rationale for each recommendation. Future revisions will include any new developments in science and data privacy.

The Reference Site Collaborative Network of the European Innovation Partnership on Active and Healthy Ageing

Seventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the same time supporting the action groups in their work. The RSCN aspires to be recognized by the EU Commission as the principal forum and authority representing all EIP on AHA Reference Sites. The RSCN will contribute to achieve the goals of the EIP on AHA by improving health and care outcomes for citizens across Europe, and the development of sustainable economic growth and the creation of jobs.

F-18-FDG-hybrid-camera-PET in patients with postoperative fever

Aim: Evaluation of F-18-FDG-hybrid-camera-PET imaging in patients with undetermined postoperative fever (POF). Methods: Prospective study of 18 patients (9 women, 9 men; age 23-85 years) suffering from POF with 2-fluoro-2’-deoxyglucose (F-18-FDG) using a dual headed coincidence camera (DHCC). Surgery had been performed 5-94 days prior to our investigation. 13 of the 18 patients received antibiotic therapy during the time of evaluation. Ten (55%) had an infectious and eight (45%) a non infectious cause of fever. Results: Increased F-18-FDG-uptake outside the surgical wound occurred in 13 regions (infection n = 11, malignancy n = 2). The sensitivity of F-18-FDG-hybrid-camera-PET in imaging infection in areas outside the surgical wound was 86% and the specificity 100%, respectively. Antibiotic therapy did not negatively influence the results of F-18-FDG-scanning. Increased F-18-FDG-uptake within the surgical wound was seen in 8 of 18 patients. The sensitivity of F-18-FDG-hybrid-camera-PET in imaging infection within the surgical wound was 100% and the specificity 56%, respectively. The interval between surgery and F-18-FDG-scanning was significantly shorter in patients with false positive results compared with patients showing true negative results (median 34 vs. 54 days; p = 0,038). Conclusion: In POF-Patients, F-18-FDG transaxial tomography performed with a F-18-FDG-hybrid-camera-PET is sensitive in the diagnosis of inflammation and malignant disease within and outside the surgical wound. Because of the accumulation of the tracer both in granulation tissue and infection, the specificity in detecting the focus of fever within the surgical wound is poor.

Safety, immunogenicity, and lot-to-lot consistency of a split-virion quadrivalent influenza vaccine in younger and older adults: A phase III randomized, double-blind clinical trial

Here, we report a randomized multicenter phase III trial assessing the lot-to-lot consistency of the 2014–2015 Northern Hemisphere quadrivalent split-virion inactivated influenza vaccine (IIV4; Sanofi Pasteur) and comparing its immunogenicity and safety with that of trivalent inactivated influenza vaccine (IIV3) in younger and older adults (EudraCT no. 2014-000785-21). Younger (18–60 y, n = 1114) and older (>60 y, n = 1111) adults were randomized 2:2:2:1:1 to receive a single dose of one of three lots of IIV4, the licensed IIV3 containing the B Yamagata lineage strain, or an investigational IIV3 containing the B Victoria lineage strain. Post-vaccination (day 21) hemagglutination inhibition antibody titers were equivalent for the three IIV4 lots. For the pooled IIV4s vs. IIV3, hemagglutination inhibition antibody titers were also non-inferior for the A strains, non-inferior for the B strain when present in the comparator IIV3, and superior for the B strain lineage when absent from the comparator IIV3. For all vaccine strains, seroprotection rates were ≥98% in younger adults and ≥90% in older adults. IIV4 also increased seroneutralizing antibody titers against all three vaccine strains of influenza. All vaccines were well tolerated, with no safety concerns identified. Solicited injection-site reactions were similar for IIV4 and IIV3 and mostly grade 1 and transient. This study showed that in younger and older adults, IIV4 had a similar safety profile as the licensed IIV3 and that including a second B strain lineage in IIV4 provided superior immunogenicity for the added B strain without affecting the immunogenicity of the three IIV3 strains.

Dermatological moulage collections in the Nordic countries

BACKGROUND

The art of producing and acquiring dermatological wax models, moulages, flourished all over Europe in the beginning of the twentieth century, whereas very little is known about the existence of moulage collections in the Nordic countries.

OBJECTIVE

The aim of this study was to elucidate the presence, the origin, the production place, the use and the condition of dermatological moulage collections in the Nordic countries.

METHODS

In each Nordic country, an extensive survey was undertaken during spring 2016. Dermatological departments, museums with medical collections, persons assumed to have specific information about wax moulages as well as secondary sources were contacted and interviewed.

RESULTS

Several hitherto undescribed collections have survived in each country, most, however, damaged and in disrepair. One Danish and part of a Finnish collection have been restored. Only few moulages are exhibited and some have been photographed and digitalized. Denmark and Sweden have had a local moulage production. Responses to the survey indicate that the result covers all collections of dermatological moulages in the Nordic countries, though some moulages may remain in private collections unknown to the authors, or uncatalogued in museums.

CONCLUSION

Moulages are medical gems from bygone days before modern technology facilitated new means of communication. Restoration and appropriate storing should be considered for at least selected items from the Nordic collections.

Why do people buy dogs with potential welfare problems related to extreme conformation and inherited disease? A representative study of Danish owners of four small dog breeds

A number of dog breeds suffer from welfare problems due to extreme phenotypes and high levels of inherited diseases but the popularity of such breeds is not declining. Using a survey of owners of two popular breeds with extreme physical features (French Bulldog and Chihuahua), one with a high load of inherited diseases not directly related to conformation (Cavalier King Charles Spaniel), and one representing the same size range but without extreme conformation and with the same level of disease as the overall dog population (Cairn Terrier), we investigated this seeming paradox. We examined planning and motivational factors behind acquisition of the dogs, and whether levels of experienced health and behavior problems were associated with the quality of the owner-dog relationship and the intention to re-procure a dog of the same breed. Owners of each of the four breeds (750/breed) were randomly drawn from a nationwide Danish dog registry and invited to participate. Of these, 911 responded, giving a final sample of 846. There were clear differences between owners of the four breeds with respect to degree of planning prior to purchase, with owners of Chihuahuas exhibiting less. Motivations behind choice of dog were also different. Health and other breed attributes were more important to owners of Cairn Terriers, whereas the dog’s personality was reported to be more important for owners of French Bulldogs and Cavalier King Charles Spaniels but less important for Chihuahua owners. Higher levels of health and behavior problems were positively associated with a closer owner-dog relationship for owners of Cavalier King Charles Spaniels and Chihuahuas but, for owners of French Bulldogs, high levels of problems were negatively associated with an intention to procure the same breed again. In light of these findings, it appears less paradoxical that people continue to buy dogs with welfare problems.

Inhibition of Photosystem II by Ioxynil in Wild Type and Resistant Mutant of Synechocystis 6714

A Synechocystis 6714 mutant resistant to the phenol-type herbicide ioxynil was isolated and characterized. Ioxynil was shown to inhibit both the donor and the acceptor sides of photosystem II, but at different concentrations. The mutation found in the psbA gene (encoding the D, protein) at codon 266 (asparagine to threonine) [G. Ajlani, I. Meyer, C. Vernotte, and C. Astier, FEBS Lett. 246, 207-210 (1989)] gives a ten-fold resistance of the acceptor side to ioxynil without any modification of the sensitivity of the donor side. Electron transfer between the primary and the secondary acceptor of photosystem II was identical in the mutant and the wild type. The mutant remains sensitive to atrazine and is even more sensitive to DCMU than the wild type.

Plasmaparameter in der Anfangsphase eines Q-switch-Laser-Funkens in Stickstoff / Plasmaparameters in the Initial Stages of Plasmas produced by a Q-switch Laser in Nitrogen

An experimental investigation of the breakdown in Nitrogen at 1.5 atm under intense radiation from a Q-switched Nd: glass Laser (peak power 1 MW) is presented. Two main techniques were used: Spectroscopic methods gave information on the axial and radial growth of the emitted light intensities. The image converter streak technique and Schlieren photography were used to investigate the propagation of the shock waves. This paper includes the radial and temporal distribution of the plasmaparameters temperature and electron density in the focus region, but also in distances of 240 /μm from the focus. It was found that local thermal equilibrium is established within about 10-14 ns, but only in a small part of the spark

Emergence of echinocandin-resistant Candida spp. in a hospital setting: a consequence of 10 years of increasing use of antifungal therapy?

Since their introduction in the 2000s, echinocandin drugs have become widely used for the treatment and prophylaxis of invasive fungal infections and, notably, invasive candidiasis. Although cases of breakthrough candidiasis in patients receiving echinocandins have been reported, clinical failure during echinocandin treatment due to the acquisition of resistance by a normally susceptible Candida spp. isolate is considered rare. To date, no publications have been published correlating the use of echinocandins and the emergence of echinocandin resistance among Candida species. So, our goal is to report an initial analysis of echinocandin use in relation to the emergence of resistant Candida isolates. We report here a single-centre experience of the emergence of eight resistant isolates belonging to normally susceptible Candida species in six patients receiving echinocandins. We describe the context and analyse the use of echinocandins over the previous decade. For seven of these isolates, we identified FKS gene mutations involved in decreased susceptibility. Seven isolates were obtained in 2011, on the heels of a ten-fold increase in caspofungin use over the preceding decade. In contrast, in 2012, the use of echinocandins decreased in our institution by 19.5 % and, in that year, only one Candida-resistant isolate was detected, despite the stable global epidemiology of invasive candidaemia. This work underlines the necessity of improving the prescription of antifungal drugs. Improvement in the monitoring of strain susceptibility should also be considered in order to better detect the emergence of resistant or non-susceptible yeast strains.
