Byline: B. Kuttler (1), K. Rosing (1), M. Lehmann (2), J. Brock (2), H. J. Hahn (1) Keywords: Key words BB rat; Islet transplantation; Rejection; Disease recurrence; Immunotherapy Abstract: Grafting autoimmune-diabetic recipients with allogeneic islets, graft rejection and disease recurrence as major problems of reaching indefinite survival and tolerance induction have to be solved. Anti-CD25 and anti-CD4 monoclonal antibodies were successfully used after allogeneic islet transplantation in experimentally diabetic rats. A temporary anti-CD25 therapy also prevented disease recurrence in autoimmune-diabetic BB rats, while this was not yet reported for an anti-CD4 treatment. In autoimmune-diabetic NOD mice disease recurrence can be successfully treated using an anti-CD4 monoclonal antibody. We, therefore, compared the efficacy of a short-term anti-CD25 and anti-CD4 treatment regarding the prevention of allograft rejection and disease recurrence in autoimmune-diabetic BB/OK rats. Both monoclonal antibodies were combined with low doses of Cyclosporin A. Untreated BB/OK rats relapsed into hyperglycaemia within 3 weeks independent of the islet donor, LEW.1A, LEW.1BB/OK or BB/OK rats. However, after grafting MHC-identical allogeneic (LEW.1BB/OK) or syngeneic (BB/OK) islets we observed about 30% spontaneous acceptance. Both the anti-CD25 and anti-CD4 therapy significantly prolonged the survival of allogeneic grafted islets. After MHC-identical allogeneic and syngeneic islet transplantation the temporary immunotherapy increased the proportion of permanent acceptors to 63% and 75%, respectively. The efficacy of both treatment strategies in prolonging allograft survival and prevention of disease recurrence was identical. In summary, anti-CD25 as well as anti-CD4 therapy prevented autoimmune but not allogeneic islet destruction in autoimmune-diabetic BB/OK rats. In conclusion, targeting different immune cells by monoclonal antibodies with different specificities can lead to very similar results with respect to an interruption of allograft rejection and autoimmune reaction.

Objectives: To describe a practical and standardized approach for acquiring international administrative routine data from different data owners for research.Methods: Best practice approach based on the experiences gained during the EU-funded ADVOCATE ("Added Value for Oral Care") project that involved the collection of routinely collected administrative data from health insurance providers, health funds or health authorities in six European countries.Results: A general process for data acquisition that contains four phases was developed: First, the conditions for data usage and access are determined. These conditions are subsequently tested by sharing and analyzing a data sample (quality and validity audit). After optimizing the process model, full-scale data access and analysis are performed.Conclusions: The general data acquisition approach has successfully been applied in the ADVOCATE project to acquire claims data from eight data owners, which prescribed different usage conditions in each case. The approach aims to make a contribution to a standardized process model for acquiring administrative routine data for research and providing researchers with a methodological framework.

24. On the Correct Number of Regions in Regionalisation Structures
- Author

Rosing, K E and van Dijk, J J
- Abstract
In region building, different models of cluster analysis conform to different theoretical spatial structures. The p-median model may be quite appropriate in nodal structures. Use of the p-median model, however, raises problems about the choice of the number of groups (p). This choice does not arise in facility location problems. An argument is made for parallel use of optimal methods and heuristics for region building. Optimal solutions are now feasible for even large problems because of the increase in computer power. Optimal methods provide one solution for each different value of p.Heuristic methods may provide different solutions for each value of p, depending on the starting position used for the heuristic. The multiple solutions from a heuristic procedure can then be interpreted as spatial competition between locations to become medians. By counting the number of times optimal and nonoptimal solutions are located by a heuristic procedure, statistics can be developed. Such statistics can then provide an objective method to select a specific number of groups over all others. Computational experience, with both heuristic and optimal methods, is presented.

- Abstract
Optimal p-median solutions were computed for six test problems on a network of forty-nine demand nodes and compared with solutions from two heuristic algorithms. Comparison of the optimal solutions with those from the Teitz and Bart heuristic indicates that this heuristic is very robust. Tests of the Maranzana heuristic, however, indicate that it is efficient only for small values of p(numbers of facilities) and that its robustness decreases rapidly as problem size increases.

26. Optimal Clustering
- Author

Rosing, K E and ReVelle, C S
- Abstract
Cluster analysis can be performed with several models. One method is to seek those clusters for which the total flow between all within-cluster members is a maximum. This model has, until now, been viewed as mathematically difficult because of the presence of products of integer variables in the objective function. In another optimization model of cluster analysis, the p-median, a central member is found for each cluster, so that relationships of cluster members with the various central members are maximized (or minimized). This problem, although mathematically tractable, is a less realistic formulation of the general clustering problem.The formulation of the maximum interflow problem is here transformed in stages into a linear analogue which is economically solvable. Computation experience with the several transformed stages is reported and a practical example of the analysis demonstrated.

- Abstract
Objectives: Oral health literacy (OHL) is suggested as an important denominator of oral health. This study aimed to identify ways to improve oral health by exploring the association between oral health literacy and oral health-related behaviours among female adolescents in the Eastern Province of the Kingdom of Saudi Arabia (KSA)., Methods: This cross-sectional study assessed OHL among 1,889 10th grade female students in the Eastern Province of the KSA. OHL was assessed using an Arabic version of the short version of the Health Literacy in Dentistry scale (A-HeLD-14). Self-reported socio-demographic information and oral health-related behaviours (toothbrushing, dental attendance, and sugary diet consumption) were also collected. The relationship between OHL and oral health-related behaviours was investigated using binary logistic regression, adjusted for socio-demographic information., Results: The binary logistic regression analyses showed that poor OHL was significantly associated with infrequent toothbrushing ( p < 0.001) and irregular dental attendance ( p = 0.005) but not with consumption of sugary diets. All A-HeLD-14 domains were significantly associated with infrequent toothbrushing, and the domains concerning access, receptivity, and financial barriers were significantly associated with irregular dental attendance. The highest odds ratios (ORs) for infrequent toothbrushing were found in the domains of receptivity (OR = 4.19) and understanding (OR = 3.85) and for irregular dental attendance in the financial barriers (OR = 1.61) and access (OR = 1.49) domains, followed by the receptivity domain (OR = 1.35)., Conclusion: Poor OHL was significantly associated with infrequent toothbrushing and irregular dental attendance. Interventions focusing on OHL are warranted to improve oral health-related behaviours and thereby oral health in the population. The aspects that seem most vital to target are improved access to dental care, including the reduction of economic barriers, as well as increased awareness of oral health in the population., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 THE AUTHORS.)

- Abstract
Background: The Arabic version of the short form of the Health Literacy in Dentistry scale (HeLD) had not yet been developed in previously published studies. This study aims to test the reliability and validity of an Arabic version of the short form of the HeLD questionnaire., Methods: The short version of HeLD was translated into Arabic and the psychometric properties were evaluated in a sample of 1,889 female students in their first year of secondary school. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC), and internal consistency reliability was assessed using Cronbach's alpha. Content validity was investigated by creating a correlation matrix between the individual items of the HeLD-14, and criterion validity was determined using Pearson's correlation between the HeLD-14 score and an overall oral health rating. Sensitivity analysis was assessed by testing the associations of the HeLD-14 score with oral health-related behaviours and residential area., Results: The Arabic version of HeLD-14 (A-HeLD-14) had acceptable ICC (0.54) and excellent internal consistency (Cronbach's alpha: 0.92). The correlations between the items of the A-HeLD-14 varied from 0.3 to 0.9. The A-HeLD-14 showed a statistically significant correlation with the overall oral health rating (r = 0.37, p < 0.001). The median A-HeLD-14 score was significantly higher in participants who brushed their teeth frequently (51.31), visited the dentist regularly (52.00), consumed fresh fruit frequently (51) and consumed soda or energy drinks infrequently (51.00) than participants who brushed their teeth infrequently (41.50), visited the dentist irregularly (49.00), consumed fresh fruit infrequently (47) and consumed soda or energy drinks frequently (48.00)., Conclusion: The A-HeLD-14 instrument demonstrates sufficient validity, reliability, and sensitivity for measuring oral health literacy among the Arabic-speaking population., (© 2024.

- Abstract
Background: Since 1972 The National Child Odontology Registry has collected data on the oral health of most of all Danish children and adolescents. However, comprehensive information on the registry has not previously been available, making it difficult to approach and use the registry for research purposes., Methods: By combining historical documentation and simple descriptive statistics we provide an overview of major events in the timeline of The National Child Odontology Registry and discuss how they impact the available data. We provide a broad overview of the dental variables in the registry, and how the registration criteria for some of the core dental variables (gingivitis, periodontitis, and dental caries) have changed over time. We then provide examples of how aggregate variables for the core dental diseases, allowing for comparison across registration criteria, can be created., Results: Most of the Danish population born during or after 1965 have a least one entry in the National Child Odontology Registry, with 68% having entries spanning their entire childhood and adolescence. The prevalence of gingivitis and periodontitis seem to increase significantly in the years immediately following changes in how registration criteria for these variables, raising questions as to whether these diseases are generally underreported, or subject to overreporting in the years following the registration changes. The mandatory ages of registration instituted in 2003, do not appear to have had a strong impact on the ages at which registrations are made. For variables not directly comparable across datasets due to changes in registration criteria aggregate variables of measurements can be computed in most cases., Conclusions: The National Child Odontology Registry provides a unique opportunity to study the impact of childhood oral health on life trajectories, but using the registry is not without issues, and we strongly recommend consulting with experts in the field of odontology to ensure the best use of available data., (© 2023.

- Abstract
Objectives: Persons with Parkinson's disease (PD) have a higher prevalence of oral diseases and orofacial dysfunction, but knowledge about the use of dental care and whether their dental care needs are met is sparse. This study aimed to investigate the dental attendance and usage of dental care services of the total PD population in Denmark and compare it with a control group., Methods: National registers were used to identify the total PD population in Denmark (n = 6874) and to obtain data on their dental care from 2015 to 2019. These data were compared with a five-fold age-, gender- and geographically matched control group without PD (n = 34 285). Register data on age, gender, civil status, educational level, income, nursing homes status and mortality were also collected and adjusted for in the analyses. The dental attendance was analysed using χ
2 -test with Bonferroni correction, and the type of dental care services was analysed using negative binomial regression analysis., Results: A significantly higher proportion of persons with PD were irregular attenders of the dental care system (21.0%), compared with the control group (16.9%). Persons with PD had a significantly higher overall usage of dental cares services. Most prominent was the high usage of treatment services, where persons with PD had a 1.50 times higher incidence rate of tooth extractions and a 1.71 times higher incidence rate of tooth fillings in the five years compared with the control group., Conclusion: Persons with PD are more often irregular users of dental care and receive more treatment services than the control group. This indicates a need for high-quality prophylactic initiatives to prevent high filling and tooth extraction rates. Furthermore, this knowledge can be used by clinicians and decision makers to ensure optimal dental care for persons with PD., (© 2022 The Authors.

- Abstract
Objective: To investigate the impact of the Covid-19 pandemic on the patient flow and economy as experienced by dental practices in Denmark., Material and Methods: A survey regarding experience of patient flow, economical turnover, financial strain and willingness to pay for large treatments during the first year of the Covid-19 pandemic (March 2020 to March 2021), along with information on the characteristics of the practice (specialist practice, ownership, practice operation and size) was distributed to all dental practices in Denmark in March 2021., Results: Of the 1728 practices, 581 (33.6%) answered the survey. A decline in patient flow and a decline in economical turnover were reported by 79% and 84.4% of the practices, respectively. Financial strain was reported by 15.8% and an increased willingness to pay for large treatments was reported by 32.1%. A large decline in turnover and financial strain were associated with non-specialized practices, practices with a single owner and small practices. Logistic regressions showed that practices not receiving referrals had an odds ratio of 2.34 (CI: 1.32-4.14) for having a large decline in economic turnover compared with practices receiving referrals and that small practices had an odds ratio of 1.92 (CI: 1.16-3.19) for reporting financial strain compared with large practices., Conclusions: Reportedly, the Covid-19 pandemic resulted in a decline in both patient flow and economical turnover in Danish dental practices. Large and more specialized practices seem to have managed the economic crisis better.

- Abstract
Objective: Planning and evaluation of oral healthcare systems rely on monitoring of care patterns. Monitoring periodontal care patterns provide information on the burden and occurrence of periodontitis in the population and on the direct financial cost. The aims of the study were to describe patterns in periodontal care among dental care attenders that might incite subsequent investigation and revised treatment guidelines. Secondly, to estimate the direct societal costs of periodontal care., Material and Methods: A retrospective register-based study utilising data from the Danish Public Health Insurance which includes all dental care attenders in 2012-2016, three years before and one year after a national risk-based recall maintenance program was rolled out in Denmark., Results: The 2.7 million yearly dental care attenders corresponded to ∼60% of the eligible population and in the range of 20-24% received periodontal care. Total expenditure for periodontal care in Denmark increased by 13% from 2012 to 2016, from €78 to €88 million. The proportion of total healthcare funding spent on periodontal care was 0.61% in 2016., Conclusions: Patients with periodontitis have large out-of-pocket yearly expenses for periodontal care. Despite small changes in periodontal clinical practice that may indicate improved targeting of patients in need of periodontal care, challenges of reaching non-attenders and non-adherence to care are unsolved. More research into outcomes from periodontal therapy in daily practice, seen from both normative and patient perspectives, would help establish knowledge of the efficiency of existing periodontal care systems and help identify barriers and facilitators for attending care in Denmark.

- Abstract
A growing number of interventions have sought to cultivate mindfulness, an accepting awareness of body and mind experiences. A great deal of prior research has shown mostly beneficial effects of mindfulness interventions. However, cultivating mindfulness may not always be beneficial for everyone. Two studies examined whether mindfulness may have alienating effects among people high in state orientation (i.e. low self-regulatory abilities). Participants were randomly assigned to either a 90-minute mindfulness training plus 5-minute retreatment or a waiting list control group (Study 1 N = 54, Study 2 N = 155). Alienation was operationalised as false self-ascriptions (FSA rate) of extrinsic goals that were allegedly recommended by experts. Participants high (versus low) in state orientation had significantly higher FSA rates in the mindfulness (versus control) condition. These results suggest that mindfulness training may alienate psychologically vulnerable populations (e.g. state-oriented people) from their intrinsic emotional preferences.

- Abstract
Objectives: A proof-of-concept study has shown that the Added Value for Oral Care (ADVOCATE) Field Studies approach (academic detailing with feedback data) is considered a feasible, useful, and acceptable way to motivate general dental practitioners (GDPs) to reflect on and, if required, change their oral health-care delivery. The aims of this proof-of-principle study were to test whether such results were reproducible and to reach consensus among stakeholders on recommendations for wider implementation., Methods: Eleven groups of GDPs were recruited in 6 countries (Denmark, England Germany, Hungary, Ireland, and The Netherlands). Each group had 3 academic detailing meetings, being stimulated by feedback data. Focus group interviews were held to evaluate the reproducibility of the Field Studies approach. A World Café session explored suggestions for the wider implementation of the approach., Results: Replicable results on feasibility, acceptability, and usefulness of the Field Studies approach were seen; 7 out of 9 themes identified in the proof-of-concept study were validated. Directed content analyses identified that adjustments to procedures to collect and present feedback data were desirable. Overall, the approach can stimulate GDPs to reflect on and change aspects of their oral health-care delivery., Conclusions: The Field Studies approach, after some adjustments to data collection procedures, is ready for further testing in larger studies., (Copyright © 2020 The Author(s).

- Abstract
Background: Academic detailing (AD) is a defined form of educational outreach that can be used to influence decision making and reduce unwarranted variation in healthcare delivery. This paper describes the results of the proof of concept phase of the ADVOCATE Field Studies. This study evaluated the feasibility, acceptability and usefulness of AD reinforced with feedback data, to promote prevention-oriented, patient-centred and evidence-based oral healthcare delivery by general dental practitioners (GDPs). Methods: In the Field Studies, six groups of GDPs ( n = 39) were recruited in The Netherlands, Germany and Denmark. Each group had four meetings reinforced with feedback data for open discussions on dental practice and healthcare delivery. Conventional and directed content analysis was used to analyze the qualitative data collected from focus group interviews, debriefing interviews, field notes and evaluation forms. Results: A total of nine themes were identified. Seven themes related to the process of the Field Studies and covered experiences, barriers and facilitators to AD group meetings, data collection and the use of an electronic dashboard for data presentation and storage. Two themes related to the outcomes of the study, describing how GDPs perceived they made changes to their clinical practice as a result of the Field Studies. Conclusions: The ADVOCATE Field Studies approach offers a novel way of collecting and providing feedback to care providers which has the potential to reduce variation oral healthcare delivery. AD plus feedback data is a useful, feasible approach which creates awareness and gives insight into care delivery processes. Some logistic and technical barriers to adoption were identified, which if resolved would further improve the approach and likely increase the acceptability amongst GDPs.

- Abstract
In this experiment, the effect of the alignment of leader behaviors with innovation requirements was investigated. A sample of N = 245 students participated in a laboratory experiment. Participants had to address either creativity or implementation requirements within a task and received a leadership manipulation in a video message. Results showed that the alignment of leader behaviors with innovation requirements led to improved performance. These findings contribute to the literature by addressing the specific requirements within the innovation process and by showing that aligning leader behaviors with these requirements contribute to performance in the innovation process., (Copyright © 2020 Gerlach, Heinigk, Rosing and Zacher.)

- Abstract
Equipping health systems with suitable incentives for efficient resource allocation remains a major health policy challenge. This study examines the impacts of 2015 regulatory changes in Danish dental care which aimed at effectuating a transition from six-to-twelve-monthly dental recall intervals, for every patient, towards a model where patients with higher need receive dental recalls systematically more frequently than patients with lower need. Exploiting administrative data from the years 2012-2016 from the Danish National Health Insurance database containing 72,155,539 treatment claims for 3,759,721 unique patients, we estimated a series of interrupted time-series regression models with patient-level fixed-effects. In comparison to the pre-reform period, the proportion of patients with recall intervals of up to 6 months was by 1.2%-points larger post-implementation; that of patients with 6-12-monthly recalls increased by 0.7%-points; that of patients with more than 12-monthly dental recalls decreased by 1.9%-points. The composition of care shifted more substantially: the proportion of treatment sessions including preventive care increased by 31.5%-points (95%-CI: 31.4;31.6); that of sessions including scaling increased by 24.1%-points (24.0;24.2); that of sessions including diagnostics decreased by 34.5%-points (34.4;34.6). These findings suggest that dental care providers may have responded differently to regulatory changes than intended by the health policy., (© 2020 The Authors.

- Abstract
Objectives: To investigate whether the location of tooth loss and prosthesis are associated with self-reported oral health, general health, socioeconomic position and satisfaction with life., Methods: From the Copenhagen Aging and Midlife Biobank (CAMB) investigation, 1517 persons had their oral status ranked (full dentition, fixed prosthesis in the masticatory zone, tooth loss in the masticatory zone, fixed prosthesis in the aesthetic zone, removable prosthesis, tooth loss in the aesthetic zone). Self-reported oral health, general health, socioeconomic position and satisfaction with life were obtained. Information on gender, normative socioeconomic position, frequency of seeing a dentist, acute dental treatment within the last 5 years and general diseases was also recorded., Results: Patients with tooth loss in the aesthetic zone and removable prosthesis showed high odds ratios for reporting poor rather than good oral health compared to patients having a full dentition. Having a removable prosthesis was further associated with rating socioeconomic position as low rather than high (odds ratio = 27.7 [95% CI: 5.07; 151.6]) compared to a full dentition after controlling for normative socioeconomic position and gender. In the bivariate analyses, a tendency towards poorer general health and poorer satisfaction with life was found with worse oral status, meanwhile the multiple regression analyses did not show significant associations between oral status and general health and satisfaction with life., Conclusions: Missing teeth and having prostheses are associated with worse self-reported oral health compared to having a full dentition. Removable dental prosthesis may be associated with a worse self-perception of socioeconomic status., (© 2019 John Wiley & Sons Ltd.)

- Abstract
Background: To examine if patients with oral lichen planus, oral lichenoid lesions and generalised stomatitis and concomitant contact allergy have more frequent and severe xerostomia, lower unstimulated and chewing-stimulated saliva and citric-acid-stimulated parotid saliva flow rates, and higher salivary concentration of total protein and sIgA than cases without contact allergy and healthy controls., Methods: Forty-nine patients (42 women, aged 61.0 ± 10.3 years) and 29 healthy age- and gender-matched subjects underwent a standardised questionnaire on general and oral health, assessment of xerostomia, clinical examination, sialometry, mucosal biopsy and contact allergy testing., Results: Nineteen patients had oral lichen planus, 19 patients had oral lichenoid lesions and 11 patients had generalised stomatitis. 38.8% had contact allergy. Xerostomia was significantly more common and severe in patients (46.9%) than in healthy controls, whereas the saliva flow rates did not differ. The patients had higher sIgA levels in unstimulated and chewing-stimulated saliva than the healthy controls. The total protein concentration in saliva was lower in the unstimulated saliva samples whereas it was higher in the chewing stimulated saliva samples from patients when compared to healthy controls. The differences were not significant and they were irrespective of the presence of contact allergy., Conclusion: Xerostomia is prevalent in patients with oral lichen planus, lichenoid lesions and generalised stomatitis, but not associated with salivary gland hypofunction, numbers of systemic diseases or medications, contact allergy, age, or gender. Salivary sIgA levels were higher in patients than in healthy controls, but did not differ between patient groups. The total salivary protein concentration was lower in unstimulated saliva samples and higher in chewing-stimulated saliva samples in patients than in healthy controls, but did not differ between patient groups. Our findings do not aid in the discrimination between OLP and OLL and these conditions with or without contact allergic reactions.

- Abstract
Objectives: To describe the pattern of dental services provided to 64-65-year-old Danes who are regular users of dental care over a 5-year period, to analyse whether this pattern is associated with socio-demographic and/or socioeconomic factors, and if different uses of dental services are related to dental status and caries experience. Finally, to discuss the future planning of dental services aimed at the increasing population of elderly citizens. [Correction made on 21 March 2014, after first online publication: The sentence 'Data on elderly's dental service are scarce, although increased use is seen and more teeth are present in this age group.' was removed.], Methods: A cross-sectional study of all aged 64-65 (n = 37 234) who received a dental examination in 2009 was conducted. Clinical data comprised dental services received under the National Health Insurance reimbursement scheme, dental status and DMFT. Geographical, socio-demographic and socioeconomic data derived from public registers., Results: Almost all received restorations, while periodontal treatment was received by <50% during 5 years. Heavy use of dental services was dominated by periodontal services. Periodontal services were most prevalent in the capital and the most affluent areas. Relatively more extractions were related to low income and persons in least affluent areas. Total number of services was highest among women, persons with ≥20 teeth, persons living in the capital, and where the ratio user per dentist was low., Conclusion: For future planning of dental care for elderly, dental status, geographical and social area-based factors and to some degree gender, income, and education must be taken into consideration as all these factors seem to influence the future demand for dental services., (© 2014 John Wiley & Sons A/S and The Gerodontology Association.

- Abstract
Objectives: To investigate whether receipt of dental services, among attenders, reflects variations in dental health or whether and to what degree it is associated with socioeconomic status, with irregular or regular dental attendance and with the availability of dentists in residential areas., Materials and Methods: This retrospective register-based study followed two Danish cohorts, aged 25 and 40, with a dental examination in 2009 (n = 32,351). The dental service data were registered during 2005-2009. The number of dental examinations, individual preventive services (IPS), tooth extractions, root fillings and composite fillings were analyzed in relation to socioeconomic status, irregular/regular dental attendance, inhabitant/dentist ratio and to DMFT at age 15 (DMFT15) and change in DMFT (ΔDMFT) from age 15 to age 25 and age 40, respectively. Poisson regression and negative binomial regression analyses were used., Results: The variations in number of services received in the study population were small (SD = 0.2-2.7). However, with a few exceptions, high levels of DMFT15 and ΔDMFT were associated with receipt of more dental services. Socioeconomically-privileged individuals received more dental examinations but fewer tooth extractions, root fillings and composite fillings compared to disadvantaged persons, when controlled for dental health levels. Irregular attenders received fewer IPS and composite fillings but had more extractions compared to regular attenders., Conclusions: Variations in dental care services were found to reflect variations in dental health, but the variations were also related to individual socioeconomic status, residential area and dental attendance patterns.

- Abstract
Background: Due to the lack of nephrotoxic activity, proliferation signal inhibitors (PSI) such as everolimus are recommended for immunosuppression after heart transplantation, but the assessment of renal function in patients receiving PSI has led to conflicting results. We examined renal integrity and function using neutrophil gelatinase-associated lipocalin (NGAL) and conventional markers [plasma creatinine, cystatin C, urine albumin, α1-microglobulin (α1M)] in heart transplant patients, who underwent conversion to everolimus due to allograft vasculopathy, graft rejection episodes, or renal function deterioration, and in patients maintained on calcineurin inhibitors (CNI)., Methods: This cross-sectional study included 121 consecutive heart transplant recipients: 44 patients received CNI-free immunosuppressive therapy with everolimus and 77 patients received CNI. Renal parameters were determined in plasma and urine samples using standard enzymatic or immunochemical methods., Results: Heart transplant recipients receiving everolimus therapy had significantly lower NGAL concentrations in plasma [median (95% CI): 128 (97-176)ng/mL vs. 252 (224-283)ng/mL, p<0.001] and urine [median (95% CI): 6.4 (4.5-7.6)ng/g vs. 15.7 (10.2-25.9)ng/g creatinine, p<0.001]. In contrast, no significant differences were observed between everolimus- and CNI-treated groups with regard to creatinine and cystatin C, as well as urine albumin and α1M levels. Significant correlations were noted between plasma NGAL and creatinine (r=0.42, p<0.001), cystatin C (r=0.44, p<0.001), N-terminal brain natriuretic propeptide (r=0.31, p<0.01) and indicators of chronic inflammation [lipoprotein-associated phospholipase A2 (Lp-PLA2), r=0.31, p<0.01] and soluble CD40 ligand (sCD40L, r=0.22, p<0.05), and between urinary NGAL and α1M (r=0.21, p<0.05). Multiple regression analysis indicated that cystatin C and Lp-PLA2 were the best predictors of plasma NGAL., Conclusion: The present study documents reduced plasma and urinary NGAL levels in the absence of differences in conventional renal parameters in patients on CNI-free immunosuppressive therapy with everolimus. These results support favorable effects of everolimus on renal integrity in heart transplant recipients., (Copyright © 2015 Japanese College of Cardiology. Published by Elsevier Ltd.

- Abstract
Background: Several studies demonstrated decreased severity and incidence of cardiac allograft vasculopathy (CAV) in heart transplant recipients receiving immunosuppressive therapy with everolimus. However, data regarding the influence of everolimus on risk factors predisposing to CAV are hitherto limited. We here systematically evaluated cardiovascular risk factors in heart transplanted patients, who underwent conversion to everolimus or were maintained on conventional therapy with calcineurin inhibitors (CNI)., Methods: 50 Patients receiving everolimus and 91 patients receiving CNI in addition to mycophenolate mofetil and low-dosed steroids were included in the study. CAV risk factors were determined in plasma or urine using standard enzymatic or immunochemical methods., Results: No significant differences were observed between both groups with regard to lipid (total, LDL- and HDL-cholesterol), metabolic (glucose, insulin), inflammatory (C-reactive protein, IL-6, myeloperoxidase) and cardiac (troponin I, NT-proBNP) risk factors. However, significantly lower activity of lipoprotein-associated phospholipase A2 (Lp-PLA2) and a negative correlation between the Lp-PLA2 activity and the everolimus concentration were observed in plasmas from everolimus-treated patients. Conversion to everolimus significantly lowered Lp-PLA2 activity in heart transplant recipients. Studies in vitro revealed reduced Lp-PLA2 expression in hepatocytes and macrophages pre-exposed to everolimus. In addition, reduced plasma markers of oxidative stress including oxidized LDL, 8-iso-prostaglandin F2α and protein carbonyls were noted in heart transplant recipients receiving everolimus therapy., Conclusion: Our results suggest that everolimus specifically lowers plasma activity and cellular production of Lp-PLA2 and thereby dampens oxidative stress. These effects may additionally contribute to the reduced CAV incidence observed in heart transplant recipients receiving everolimus therapy., (© 2013 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
In this study, the authors investigated leader generativity as a moderator of the relationships between leader age, leader-member exchange, and three criteria of leadership success (follower perceptions of leader effectiveness, follower satisfaction with leader, and follower extra effort). Data came from 128 university professors paired with one research assistant each. Results showed positive relationships between leader age and leader generativity, and negative relationships between leader age and follower perceptions of leader effectiveness and follower extra effort. Consistent with expectations based on leadership categorization theory, leader generativity moderated the relationships between leader age and all three criteria of leadership success, such that leaders high in generativity were better able to maintain high levels of leadership success at higher ages than leaders low in generativity. Finally, results of mediated moderation analyses showed that leader-member exchange quality mediated these moderating effects. The findings suggest that, in combination, leader age and the age-related construct of generativity importantly influence leadership processes and outcomes., ((c) 2011 APA, all rights reserved.)
