A thoracic aortic aneurysm (TAA) is often considered a precursor to an acute type A aortic dissection (ATAAD), a life-threatening condition requiring immediate surgical intervention. While both conditions share histopathological similarities, less is known about their overlap in clinical cardiovascular risk factors. This study aimed to map the cardiovascular disease burden in patients with ATAAD and compare it with patients with TAA.

A multicentre retrospective study.

The data were collected from electronic health records of two academic hospitals located in the Netherlands.

Patients who were treated surgically for ATAAD or TAA between 2000 and 2022 were eligible. This study included 731 patients with ATAAD and 480 patients with TAA.

Hypertension was equally prevalent in both groups (50.9% vs 50.6%, p=0.921). Diabetes was uncommon (3.3% vs 6.7%, p=0.638). Hyperlipidaemia (9.6% vs 20.0%, p=0.001) and peripheral arterial disease (8.8% vs 22.7%, p

This study suggests distinct cardiovascular risk profiles in patients with ATAAD and patients with TAA, highlighting the importance of tailored treatment strategies for aortic disease. Further research is needed to investigate the pathophysiological mechanisms underlying these differences and their impact on thoracic aortopathy.

The long-term success of metabolic and bariatric surgery (MBS) depends largely on adherence to health-promoting behaviour following MBS. Especially, adherence to healthy dietary behaviour in line with guidelines appears to be of the utmost importance. The primary objective of the present study is to evaluate the effect of adherence to dietary behaviour recommendations and the percentage of total weight loss (%TWL) after MBS. Adherence is hypothesised to have a positive influence on the %TWL, 24 months after MBS. Furthermore, we investigate the association of various sociodemographic, organisational, psychological and behavioural factors prior to and after MBS and their effect on %TWL.

The present study is a single-centre observational, prospective, longitudinal cohort study conducted in Germany. Data are collected at nine measurement points (T0: 4 weeks prior to MBS; T1: 2 weeks after MBS, T2: 5 weeks after MBS; T3: 3 months after MBS; T4: 6 months after MBS; T5: 12 months after MBS; T6: 18 months after MBS; T7: 24 months after MBS; and T8: 36 months after MBS). Adherence to dietary behaviour recommendations is assessed using the Dietary Behavior Inventory-Surgery (DBI-S). N=325 patients applying for MBS will be included in the study. A regression analysis approach is chosen to answer the primary research question. The primary outcome %TWL is regressed at T7 (24 months after MBS) in a causal analysis on dietary adherence (DBI-S score) at T3–T7, with the covariates age, gender, marital status, educational attainment, employment status, Patient Health Questionnaire-4 score and body mass index at T0 and MBS method at T1. Stepwise hierarchical regression analyses are performed and analysed for significant model differences using ² difference tests. Effect sizes are estimated by R². Group differences are analysed using t-tests and Analyses of variance (ANOVAs). Bivariate correlations of continuous variables are examined using regression/correlation analyses.

The Ethics Committee of the Medical Faculty of the University of Essen-Duisburg has approved the conduct of the study (24-11969-BO). Results will be disseminated through manuscripts in clinical/academic peer-reviewed journals, presentations at academic conferences and communications with partners, participants and other stakeholders. Key findings will also be published in lay language on a publicly accessible website and disseminated via various (social) media channels.

The study has been prospectively registered on 8 October 2024 in the German Clinical Trials Register (DRKS00034888).

Care pathways (CPs) are widely used to standardise and improve healthcare delivery. However, CP development is often shaped by value (or normative) complexity. This study empirically explores how value complexity unfolds in a CP development programme.

A qualitative single-case study was conducted as part of a 2-year action research programme. The study followed a ‘research-follow-action’ strategy, in which action and learning occurred during the programme phase, followed by retrospective analysis using Greenhalgh et al’s ‘rules of thumb’ as a reflective lens.

A Dutch specialised rehabilitation hospital (13 sites, 800 employees approximately, ~16 000 patients annually). In three CP development cycles, 11 multidisciplinary teams were guided in CP development in a quality collaborative approach.

26 respondents participated in 44 reflective conversations; 19 respondents completed reflective questionnaires and 169 participatory observation reports were included. Participants were purposively sampled and included representatives from the leadership triad (rehabilitation physicians, managers and healthcare professionals) and members of senior management involved in CP development.

Two overarching themes were identified: goal (mis)alignment and prolonged decision-making processes negatively impacted motivation and impeded CP development. Goal alignment between stakeholders was hindered by shifting organisational priorities, creating tensions between improving care quality and ensuring financial viability. Decision-making was challenged by role uncertainty and the complexities of multidisciplinary collaboration in CP development teams. Reflective dialogues, small-scale experimentation and financial modelling supported teams in navigating these tensions to varying degrees.

This study illustrates how value complexity unfolds in CP development and underscores the importance of ongoing stakeholder management, reflectivity, formative evaluation and dialogue. Greenhalgh et al’s rules of thumb provided interpretive value in exploring these complexities but require a solid theoretical understanding and an awareness of the rules’ interrelationships. A complexity-informed approach integrating ongoing reflection and adaptability can enrich CP development methodologies, enabling healthcare professionals and action researchers to engage constructively with value complexity in complex change processes. Further research is needed to develop and implement practical strategies for enhancing stakeholder engagement and decision-making in diverse healthcare settings.

The principal aim of this study was to investigate differences in the characteristics and physiological parameters of critically ill patients who underwent interhospital transportation.

Prospective observational cohort study.

Multicentre study within the Euregio Meuse-Rhine, including Dutch and German hospitals.

A representative sample of critically ill adult patients who underwent interhospital transport accompanied by a physician was included.

None.

Data on patient characteristics, transport logistics, interventions and adverse events were recorded using an online questionnaire. The cohort was divided into Dutch and German subsets and further stratified based on the transportation modality. Descriptive statistics were utilised to present the cohort characteristics.

Dutch patients (89%) were mainly transported by mobile intensive care unit (MICU). For the present investigation, in Germany, the Intensivtransportwagen was included in this MICU category, whereas German patients (48%) were mainly transported by intensive care ambulance (ICA). An intensivist accompanied most transports in the Netherlands, whereas various specialists transported patients in Germany. Interventions were primarily performed in the MICU for Dutch patients and in the ICA for German patients. Adverse events were reported in 5% of the cases.

These comprehensive data provide insights into the transportation differences of critically ill patients. This serves as a foundation for future investigations concerning the quality and efficacy of interhospital transportation.

This study was registered in the Dutch National Trial Registration (NTR4937).

Despite being a leading cause of female morbidity and mortality, female-specific cardiovascular disease (CVD) is understudied, underdiagnosed and undertreated. Pregnancy complications involving the placenta, including pre-eclampsia, pregnancy-induced hypertension and foetal growth restriction, are thought to reflect global maternal vascular derangements that indicate a twofold to eightfold increased risk of future CVD. This calls for a better understanding of female cardiovascular pathophysiology to allow development of targeted screening and prevention strategies.

Acute atherosis is a placental vascular lesion, which histologically resembles systemic atherosclerosis. The PlacEntal Acute atherosis RefLecting Subclinical atherosclerosis study investigates the association between placental acute atherosis lesions and subclinical systemic atherosclerosis up to 20 years postpartum.

This study will improve our understanding of the relationship between pregnancy complications and CVD to identify potential prevention targets and treatments. In addition, it could determine whether the placenta can improve identification of young women at high risk of CVD. These women could benefit from risk-reducing interventions.

This longitudinal prospective cohort study will include women who are either currently pregnant or from a historical cohort. Both groups will have placental histopathology and a single postpartum CVD assessment. The CVD assessment will include medical history taking, blood tests, electrocardiography and echocardiography. Additionally, coronary CT angiography focusing on the presence of atherosclerotic plaques and calcium score will be carried out.

The currently pregnant women will either have a pre-eclamptic pregnancy (pre-eclamptic group) or an uncomplicated normotensive pregnancy (uncomplicated group), and their placenta will be collected prospectively. The single CVD assessment will be carried out 6–36 months postpartum.

Women from the historical cohort had a pre-eclamptic pregnancy 10–20 years ago. Placental tissue is available for reanalysis. The single CVD assessment will take place immediately and corresponds with 10–20 years postpartum.

Exclusion criteria are contraindications to diagnostic assessment necessities: iodinated contrast, beta-blockers or glyceryl trinitrate. Women with uncomplicated pregnancies will be excluded if they have a pre-existing auto-immune condition, chronic hypertension or diabetes mellitus. In the pre-eclamptic group, there are no additional exclusion criteria.

Ethical approval was granted by the Medical Ethics Committee in Maastricht University Medical Centre+ (NL52556.068.15/METC152019). Participants will give written informed consent. Results will be shared in peer-reviewed journals and conference presentations.

Breast cancer is the most common form of cancer in women. A considerable number of women with breast cancer who have been treated with chemotherapy subsequently develop neurological symptoms such as concentration and memory difficulties (also known as ‘chemobrain’). Currently, there are no validated therapeutic approaches available to treat these symptoms. Cognitive training holds the potential to counteract cognitive impairment. Combining cognitive training with concurrent transcranial direct current stimulation (tDCS) could enhance and maintain the effects of this training, potentially providing a new approach to treat post-chemotherapy subjective cognitive impairment (PCSCI). With this study, we aim to investigate the effects of multi-session tDCS over the left dorsolateral prefrontal cortex in combination with cognitive training on cognition and quality of life in women with PCSCI.

The Neuromod-PCSCI trial is a monocentric, randomised, double-blind, placebo-controlled study. Fifty-two women with PCSCI after breast cancer therapy will receive a 3-week tDCS-assisted cognitive training with anodal tDCS over the left dorsolateral prefrontal cortex (target intervention), compared with cognitive training plus sham tDCS (control intervention). Cognitive training will consist of a letter updating task. Primary outcome will be the performance in an untrained task (n-back task) after training. In addition, feasibility, safety and tolerability, as well as quality of life and performance in additional untrained tasks will be investigated. A follow-up visit will be performed 1 month after intervention to assess possible long-term effects. In an exploratory approach, structural and functional MRI will be acquired before the intervention and at post-intervention to identify possible neural predictors for successful intervention.

Ethical approval was granted by the ethics committee of the University Medicine Greifswald (BB236/20). Results will be available through publications in peer-reviewed journals and presentations at national and international conferences.

The Dutch Head and Neck Audit–Oral Cavity (DHNA-OC) cohort was collected to study the quality of care, current treatment and survival for oral cavity cancer (OCC) across all hospitals treating head and neck cancer (HNC) in the Netherlands.

The DHNA-OC is a registry-based national cohort of 2545 first primary OCC patients treated with curative intent between 2018 and 2021. All 14 HNC hospitals in the Netherlands contributed, guaranteeing national coverage. The DHNA-OC cohort is an elaborate dataset including variables on patient and tumour characteristics, treatment, complications, recurrence rates and survival.

The median age at diagnosis was 67 years and most tumours were early stage (cT1 in 32% and cT2 in 31%). Tongue tumours were most common, and surgery was performed in 91.3% of the patients. The number of included patients per hospital varied from 82 to 367. The proportion of advanced tumour stage varied significantly between hospitals. Substantial data completeness was acquired with only two variables exceeding 10% missing (comorbidities and performance score).

The DHNA-OC cohort will be used to study benchmarking of and current knowledge gaps in OCC care. Collaboration with other institutions or national/regional databases is highly encouraged. Some examples of planned studies are the assessment of hospital variation in outcome indicators for surgery and population-based treatment effects. The results of these studies will be used to identify best practices and continue improving the quality of care. Longitudinal cohort follow-up and enrolment will continue prospectively.

Children with Medical Complexities (CMC) often require 24/7 expert care, which frequently necessitates prolonged (re)admissions to a university medical centre (UMC), thereby impeding discharge to home. The transition from hospital to home for CMC is a multifaceted process with numerous challenges and obstacles. This protocol describes the evaluation of an innovative transitional care unit (TCU), where families can stay together in a home-like environment between hospital and home. Under the supervision of healthcare professionals, parents are supported in preparing for a sustainable home situation. We hypothesise that an intermediate stay at the Jeroen Pit Huis (JPH) will have a favourable effect on healthcare consumption, patient, parent and family-relevant outcomes in comparison to discharge directly from a hospital ward to home. Therefore, the purpose of this study is to compare the transition via the TCU JPH versus transition from hospital ward to home as provided elsewhere for CMC patients in the Netherlands.

This observational prospective cohort study compares patients who transition directly from hospital to home with those who transition via the TCU. The control group comprises five UMCs in the Netherlands. Data will be collected by extracting information from electronic health records and through online questionnaires. Parents complete questionnaires at three time points: on discharge home, 3 months and 12 months postdischarge. Bayesian inverse probability weighting will be used to control for confounding effects and analyse the results.

Ethical approval was granted by the Amsterdam UMC Medical Ethics Committee (W20_220#20.007). The need for ethical approval was waived by all other participating UMCs. Results will be disseminated through peer-reviewed scientific journals and conference presentations. The insights gained from this study will contribute to the development of a national care pathway to enhance transitional care for CMC and their families in the future.

In this study, we evaluate the long-term effects (±1.5 years postintervention) of 6-year exposure to the Lekker Fit! intervention on physical fitness and physical activity (PA).

The retrospective intervention evaluation is embedded within the Generation R Study in Rotterdam, the Netherlands, a population-based prospective birth cohort study.

Measurements took place in the research centre of the Generation R cohort study.

5489 adolescents from the Generation R Study were eligible for inclusion within this study. Successful linking to school career data was possible for 4129 adolescents who were then retrospectively subdivided into a Lekker Fit! group, mixed group and regular school group based on their primary school career.

The Lekker Fit! intervention is a multicomponent primary school-based intervention for the prevention of overweight. It focuses on a healthy diet and healthy lifestyle rather than focusing directly on the reduction of overweight. The intervention targets individual behaviour of children as well as their obesogenic environment and parental engagement in shaping their children’s behaviour.

Aged 13/14 years old, physical fitness was measured with an incremental ergometer test. The actual highest achieved work rate was divided by the expected highest achieved work rate (age- and sex-related Dutch population-based reference data), and converted into z-scores. PA was determined by the number of days with at least 1 hour of PA, obtained by a self-reported questionnaire. Propensity score matching was performed to correct for non-random selection bias. Linear regression analyses were performed to estimate intervention effects.

Children from the Lekker Fit! group had significantly lower fitness z-scores (–0.18 (95% CI –0.29 to –0.06), n=1826) compared with children from the matched regular school group. No Lekker Fit! intervention effect was found on PA (–0.12 (95% CI –0.36 to 0.12), n=1258).

No evidence was found for long-term favourable effects of a school-based multicomponent intervention on physical fitness and PA. Recommendations for policy and future research are discussed.
