Recent genomic studies have allowed the subdivision of intracranial ependymomas into molecularly distinct groups with highly specific clinical features and outcomes. The majority of supratentorial ependymomas (ST-EPN) harbor ZFTA-RELA fusions which were designated, in general, as an intermediate risk tumor variant. However, molecular prognosticators within ST-EPN ZFTA-RELA have not been determined yet.

Background: Injury prevalence is a metric which can be used to understand healthcare utilisation and prioritise injuries based on the magnitude of the injury rate. Given the ageing population in high-income countries and subsequently ageing of the injured population, the probability of long-term or permanent consequences of injuries is also likely to increase. By understanding past trends and exploiting patterns of prevalence injury rates (PIRs), future PIRs can be predicted.

Introduction And Objectives: Patients undergoing percutaneous coronary intervention in vessels with moderate-to-severe tortuosity are at higher risk of adverse outcomes, but data are scarce in the era of newer-generation stents. We compared outcomes following percutaneous coronary intervention in vessels with moderate-to-severe tortuosity using a bioresorbable-polymer sirolimus-eluting stent (BP-SES) vs a durable-polymer everolimus-eluting stent.

Methods: A total of 2350 patients from the BIOFLOW II, IV, and V randomized trials were stratified into 2 groups based on target-vessel tortuosity: none-to-mild and moderate-to-severe.

Search for surrogate markers to predict end stage kidney disease in long term lithium users.

Int J Bipolar Disord

January 2025

Department of Nephrology, Jeroen Bosch Ziekenhuis, 's-Hertogenbosch, The Netherlands.

Background: A surrogate marker (a substitute indicator of the true outcome) is needed to predict subgroups of long-term lithium users at risk of end-stage kidney disease (ESKD). In this narrative review the aim is to determine the optimal surrogate endpoint for ESKD in long-term lithium users in a scientific context.

We investigated gene-environment interaction in ADHD traits, focusing on environmental variables related to personality traits, school environment, satisfaction with life, and callousness. Using data from 2170 16-year-old twins and state-of-the-art methodology to prevent spurious findings due to measurement scale artifacts, gene-environment interaction models were estimated separately for the two core ADHD dimensions, hyperactivity-impulsivity, and inattentiveness. Based on scores on the SWAN questionnaire, where high scores are reflective of low ADHD traits, results showed that additive genetic influences were more important in explaining individual differences in the degree of hyperactivity-impulsivity in twins with a high score on the trait conscientiousness than in twins with a moderate or low score (e.

Int J Cardiol Cardiovasc Risk Prev

March 2025

Department of Public and Occupational Health, Amsterdam Public health Research Institute, Amsterdam university Medical Center, University of Amsterdam, Amsterdam, the Netherlands.

Background: Chronic inflammation is a well-recognized contributor to hypertension pathogenesis. However, the role of targeting inflammation in hypertension treatment, particularly through modulation of inflammatory markers like interleukin-6 (IL-6), remains less understood. We investigated the effects of antihypertensive medications with and without IL-6-lowering properties on long-term blood pressure (BP) control in a multi-ethnic cohort in the Netherlands.

Aiming for precision: personalized medicine through sepsis subtyping.

Burns Trauma

January 2025

Amsterdam University Medical Center, University of Amsterdam, Center of Experimental and Molecular Medicine & Division of Infectious Diseases, Amsterdam Institute for Infection and Immunity, Amsterdam, the Netherlands.

According to the latest definition, sepsis is characterized by life-threatening organ dysfunction caused by a dysregulated host response to an infection. However, this definition fails to grasp the heterogeneous nature and the underlying dynamic pathophysiology of the syndrome. In response to this heterogeneity, efforts have been made to stratify sepsis patients into subtypes, either based on their clinical presentation or pathophysiological characteristics.

Background: Patients with systemic right ventricle (SRV), either d-transposition of the great arteries following an atrial switch procedure or congenitally corrected transposition of the great arteries, develop severe right ventricular dysfunction, prompting appropriate medical therapy. However, the efficacy of beta-blockers and angiotensin receptor blockers or angiotensin-converting enzyme inhibitors (ACEI) in SRV patients is unproven.

Objectives: The objective of this study was to determine the effects of ACEI/ARB and beta-blockers on outcomes in SRV patients after accounting for likely cofounders affecting their use.

Acad Med

December 2024

K.M.J.M.H. Lombarts is professor, Professional Performance & Compassionate Care Research Group, Department of Medical Psychology, Amsterdam University Medical Center, University of Amsterdam, and researcher, Quality of Care Program, Amsterdam Public Health Research Institute, Amsterdam, the Netherlands.

Purpose: Cultures of wellness, defined as shared norms, values, attitudes, and behaviors that promote personal and professional growth and well-being, are robust determinants of professional fulfillment and professional performance. A major and largely overlooked aspect of a culture of wellness in medicine is residents' perceived appreciation or experience of feeling valued. Considering the pressing workforce and retention challenges that residency programs face, this study addressed the following research questions: How does appreciation at work manifest in the eyes of residents and how do residents perceive appreciation in relation to their professional fulfillment and performance?

Method: Guided by an interpretative phenomenological approach, this qualitative study purposively sampled 12 residents from different specialties, training years, regions in the Netherlands, and genders.
