Power, legitimacy and urgency:Unravelling the relationship between Dutch healthcare organisations and their financial stakeholders

Healthcare organisations rely on their financial stakeholders for capital to invest in state-of-the-art buildings, equipment, innovation and the delivery of healthcare services. Nevertheless, relations between healthcare organisations and their financial stakeholders have not been well studied. Here, we studied the relations between Dutch healthcare organisations and two of their main financial stakeholders (banks and health insurers) against the backdrop of system reforms and the financial crisis. We conducted a survey of healthcare executives to evaluate their relations with banks and health insurers in terms of power, legitimacy and urgency. These three attributes are based on the salience model of Mitchel, Agle and Wood (1997). We further tested for differences in power, legitimacy and urgency across organisational sector and size. The results showed that healthcare organisations value banks as legitimate stakeholders with a well-demarcated influence and a clear-cut function. The relationship with health insurers is more complex. Healthcare organisations experience considerable influence from health insurers but question the legitimacy of their claims. Since health insurers play a crucial role in the Dutch healthcare system, these findings question the workability of the relationship between healthcare organisations and health insurers and the position of health insurers in the overall healthcare sector. Our results are relevant to countries with public-private health systems and contribute to the development of the salience model by showing the individual value of stakeholder attributes and the relevance of context

De ggz in relatie tot zorgverzekeraars; een verkenning

Achtergrond In 2020 heeft Zorgverzekeraars Nederland (ZN) in ‘De GGZ in 2025. Vergezicht op de geestelijke gezondheidszorg’ een visie gepresenteerd op de toekomst van de geestelijke gezondheidszorg in Nederland. Dit document kan gezien worden als markering van het gegeven dat belangrijke belanghebbenden een gemeenschappelijke visie op de toekomst van de ggz in Nederland hebben. Contractering van zorg verloopt vaak moeilijk. Het spanningsveld tussen het leveren van kwalitatief goede en voldoende zorg en beschikbare financiering leidt tot fricties. Congruentie in visie, doelen en praktijken zijn belangrijke voorwaarden voor adequate relatievorming. Draagt het visiedocument daaraan bij?Doel Het systematisch in beeld brengen van de percepties van ggz-bestuurders en zorgverzekeraars gerelateerd aan hetproces van contractering en het verloop daarvan in de tijd.Methode Afname van interviews bij zowel bestuurders van ggz-instellingen als de strategische (beleids)adviseurs van zorgverzekeraars. In de aanpak maakten we gebruik van het saliencemodel.Resultaten De relatie tussen ggz-bestuurders en zorgverzekeraars werd als wantrouwend en complex ervaren, en was in 2021 iets verslechterd ten opzichte van 2019. De ervaren macht, legitimiteit en urgentie waren van invloed op de relatie. Vrijwel alle zorgverzekeraars werden op basis van het saliencemodel getypeerd als dominante belanghebbende. Beide partijen stonden open voor het verbeteren van de relatie, waarvoor meer transparantie en wederzijds begrip nodig was.Conclusie Met de gedragen inhoud van het visiedocument is er in zekere mate sprake van ‘shared governance’. De veranderingsstappen (‘shared innovation’) die wenselijk geacht worden, zullen bevorderd worden door de beoogde voordelendeels aan elkaar te gunnen (‘shared savings’)

Plasma Metabolomics Identifies Markers of Impaired Renal Function: A Meta-analysis of 3089 Persons with Type 2 Diabetes

CONTEXT: There is a need for novel biomarkers and better understanding of the pathophysiology of diabetic kidney disease. OBJECTIVE: To investigate associations between plasma metabolites and kidney function in people with type 2 diabetes (T2D). DESIGN: 3089 samples from individuals with T2D, collected between 1999 and 2015, from 5 independent Dutch cohort studies were included. Up to 7 years follow-up was available in 1100 individuals from 2 of the cohorts. MAIN OUTCOME MEASURES: Plasma metabolites (n = 149) were measured by nuclear magnetic resonance spectroscopy. Associations between metabolites and estimated glomerular filtration rate (eGFR), urinary albumin-to-creatinine ratio (UACR), and eGFR slopes were investigated in each study followed by random effect meta-analysis. Adjustments included traditional cardiovascular risk factors and correction for multiple testing. RESULTS: In total, 125 metabolites were significantly associated (PFDR = 1.5×10-32 - 0.046; β = -11.98-2.17) with eGFR. Inverse associations with eGFR were demonstrated for branched-chain and aromatic amino acids (AAAs), glycoprotein acetyls, triglycerides (TGs), lipids in very low-density lipoproteins (VLDL) subclasses, and fatty acids (PFDR < 0.03). We observed positive associations with cholesterol and phospholipids in high-density lipoproteins (HDL) and apolipoprotein A1 (PFDR < 0.05). Albeit some metabolites were associated with UACR levels (P < 0.05), significance was lost after correction for multiple testing. Tyrosine and HDL-related metabolites were positively associated with eGFR slopes before adjustment for multiple testing (PTyr = 0.003; PHDLrelated < 0.05), but not after. CONCLUSIONS: This study identified metabolites associated with impaired kidney function in T2D, implying involvement of lipid and amino acid metabolism in the pathogenesis. Whether these processes precede or are consequences of renal impairment needs further investigation

Genome-wide meta-analysis uncovers novel loci influencing circulating leptin levels.

Leptin is an adipocyte-secreted hormone, the circulating levels of which correlate closely with overall adiposity. Although rare mutations in the leptin (LEP) gene are well known to cause leptin deficiency and severe obesity, no common loci regulating circulating leptin levels have been uncovered. Therefore, we performed a genome-wide association study (GWAS) of circulating leptin levels from 32,161 individuals and followed up loci reaching P&lt;10(-6) in 19,979 additional individuals. We identify five loci robustly associated (P&lt;5 × 10(-8)) with leptin levels in/near LEP, SLC32A1, GCKR, CCNL1 and FTO. Although the association of the FTO obesity locus with leptin levels is abolished by adjustment for BMI, associations of the four other loci are independent of adiposity. The GCKR locus was found associated with multiple metabolic traits in previous GWAS and the CCNL1 locus with birth weight. Knockdown experiments in mouse adipose tissue explants show convincing evidence for adipogenin, a regulator of adipocyte differentiation, as the novel causal gene in the SLC32A1 locus influencing leptin levels. Our findings provide novel insights into the regulation of leptin production by adipose tissue and open new avenues for examining the influence of variation in leptin levels on adiposity and metabolic health

The trans-ancestral genomic architecture of glycemic traits

Glycemic traits are used to diagnose and monitor type 2 diabetes and cardiometabolic health. To date, most genetic studies of glycemic traits have focused on individuals of European ancestry. Here we aggregated genome-wide association studies comprising up to 281,416 individuals without diabetes (30% non-European ancestry) for whom fasting glucose, 2-h glucose after an oral glucose challenge, glycated hemoglobin and fasting insulin data were available. Trans-ancestry and single-ancestry meta-analyses identified 242 loci (99 novel; P < 5 x 10(-8)), 80% of which had no significant evidence of between-ancestry heterogeneity. Analyses restricted to individuals of European ancestry with equivalent sample size would have led to 24 fewer new loci. Compared with single-ancestry analyses, equivalent-sized trans-ancestry fine-mapping reduced the number of estimated variants in 99% credible sets by a median of 37.5%. Genomic-feature, gene-expression and gene-set analyses revealed distinct biological signatures for each trait, highlighting different underlying biological pathways. Our results increase our understanding of diabetes pathophysiology by using trans-ancestry studies for improved power and resolution.A trans-ancestry meta-analysis of GWAS of glycemic traits in up to 281,416 individuals identifies 99 novel loci, of which one quarter was found due to the multi-ancestry approach, which also improves fine-mapping of credible variant sets.Diabetes mellitus: pathophysiological changes and therap

The Influence of Age and Sex on Genetic Associations with Adult Body Size and Shape : A Large-Scale Genome-Wide Interaction Study

Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age-and/or sex-specific effects of genetic variants on BMI and WHRadjBMI, we performed meta-analyses of 114 studies (up to 320,485 individuals of European descent) with genome-wide chip and/or Metabochip data by the Genetic Investigation of Anthropometric Traits (GIANT) Consortium. Each study tested the association of up to similar to 2.8M SNPs with BMI and WHRadjBMI in four strata (men 50y, women 50y) and summary statistics were combined in stratum-specific meta-analyses. We then screened for variants that showed age-specific effects (G x AGE), sex-specific effects (G x SEX) or age-specific effects that differed between men and women (G x AGE x SEX). For BMI, we identified 15 loci (11 previously established for main effects, four novel) that showed significant (FDR= 50y). No sex-dependent effects were identified for BMI. For WHRadjBMI, we identified 44 loci (27 previously established for main effects, 17 novel) with sex-specific effects, of which 28 showed larger effects in women than in men, five showed larger effects in men than in women, and 11 showed opposite effects between sexes. No age-dependent effects were identified for WHRadjBMI. This is the first genome-wide interaction meta-analysis to report convincing evidence of age-dependent genetic effects on BMI. In addition, we confirm the sex-specificity of genetic effects on WHRadjBMI. These results may providefurther insights into the biology that underlies weight change with age or the sexually dimorphism of body shape.Peer reviewe

Smart Method for Self-Organization in Last-Mile Parcel Delivery

Parcel delivery operators experience an increasing pressure to meet the strongly growing demand for delivery services, while protecting city livability and the environment. Improving the performance of the last mile of delivery is considered key in meeting this challenge as it forms the most inefficient, expensive, and environmentally unfriendly part of delivery operations. A primary cause is a significant duplication of service areas, resulting in redundant vehicle kilometers traveled. In this paper, a new method is presented that allows for the allocation of parcels to delivery vehicles and construction of vehicle routes in real time through an auctioning system. These tasks are performed in a self-organizing manner by vehicles, parcels, and a supporting platform, to allow for collaborative and intermodal delivery. The performance of this new method is tested and compared against the currently used techniques using an agent-based simulation model. The new method manages to greatly improve the efficiency, robustness, and flexibility of delivery operations
