Subpulmonary ventricular function and inflammation are related to clinical heart failure in patients with a systemic right ventricle.

Background: Timely diagnosis of heart failure (HF) in patients with a systemic right ventricle (sRV) is difficult but important since clinical deterioration is fast once HF develops. We aimed to compare echocardiography and biomarker profile between sRV patients with and without HF and patients with a systemic left ventricle diagnosed with HF (sLV-HF).

Methods And Results: Eighty-seven sRV patients and 30 sLV-HF patients underwent echocardiographic evaluation and blood sampling.

Palliative care of proximal femur metastatic disease and osteolytic lesions: results following surgical and radiation treatment.

Background: Femoral bone metastases (FBM) or lesions (FBL) can lead to loss of mobility and independence due to skeletal-related events (SRE), e.g. pain, deformity and pathological fractures.

Atrial arrhythmia and heart failure in adult patients with congenital heart disease: a retrospective cohort study.

Background: Atrial arrhythmias (AA) and heart failure (HF) are major causes of hospitalisation in adult congenital heart disease (ACHD). This study aimed to evaluate the temporal relationship between AA and HF onset, the association between HF and the success of radiofrequency ablation (RFA), and how HF influences outcomes in patients with AA.

Methods: In this single-centre retrospective cohort study, data from 3995 patients with ACHD were analysed.

Nurse-related behavioural determinants associated with healthy eating support provided by Dutch community nurses: a cross-sectional study.

Background: Community nurses (CNs) play an important role in supporting healthy lifestyles, including healthy eating behaviour of patients. However, many CNs do not incorporate healthy eating support in their daily routines to the fullest extent possible. This study aimed to explore (1) the associations between nurse-related behavioural determinants and self-reported healthy eating support practices of Dutch CNs and (2) CNs' need for additional knowledge.

Variable-RBE-induced NTCP predictions for various side-effects following proton therapy for brain tumors - Identification of high-risk patients and risk mitigation.

Background And Purpose: Disregarding the increase of relative biological effectiveness (RBE) may raise the risk of acute and late adverse events after proton beam therapy (PBT). This study aims to explore the relationship between variable RBE (above 1.1)-induced normal tissue complication probabilities (NTCP) and patient-specific factors, identify patients at high risk of RBE-induced NTCP increase, and assess risk mitigation by incorporating RBE variability into treatment planning.

Proton therapy has witnessed growing popularity in oncology over recent decades, and researchers are increasingly looking to develop AI and machine learning tools to aid in various steps of the treatment planning and delivery processes. This review delves into the emergent role of AI in proton therapy, evaluating its development, advantages, intended clinical contexts, and areas of application.

A retrospective study: Long term prognosis in adults with PA-VSD-MAPCAs.

Background: Pulmonary Atresia, Ventricular Deptal Defect, and Major Aortopulmonary Collateral Arteries (PA-VSD-MAPCAs) is a congenital cyanotic heart defect with poor prognosis. Due to its complex and highly variable anatomy, the best treatment plan is not clear. We aimed (1) to investigate the survival of PA-VSD-MAPCAs patients according to the underlying original anatomy and treatment strategy, and (2) to evaluate life expectancy between patients with or without severe hypoplastic native pulmonary arteries (NPAs) after surgical versus non-surgical treatment.

Diffusion decrease in normal-appearing white matter structures following photon or proton irradiation indicates differences in regional radiosensitivity.

Purpose: Radio(chemo)therapy (RCT) as part of the standard treatment of glioma patients, inevitably leads to radiation exposure of the tumor-surrounding normal-appearing (NA) tissues. The effect of radiotherapy on the brain microstructure can be assessed by magnetic resonance imaging (MRI) using diffusion tensor imaging (DTI). The aim of this study was to analyze regional DTI changes of white matter (WM) structures and to determine their dose- and time-dependency.

Long-term outcome after the Ross procedure in 173 adults with up to 25 years of follow-up.

Objectives: The potential risk of autograft dilatation and homograft stenosis after the Ross procedure mandates lifelong follow-up. This retrospective cohort study aimed to determine long-term outcome of the Ross procedure, investigating autograft and homograft failure patterns leading to reintervention.

Methods: All adults who underwent the Ross procedure between 1991 and 2018 at the University Hospitals Leuven were included, with follow-up data collected retrospectively.

High-precision stereotactic irradiation for focal drug-resistant epilepsy versus standard treatment: a randomized waitlist-controlled trial (the PRECISION trial).

Introduction: The standard treatment for patients with focal drug-resistant epilepsy (DRE) who are not eligible for open brain surgery is the continuation of anti-seizure medication (ASM) and neuromodulation. This treatment does not cure epilepsy but only decreases severity. The PRECISION trial offers a non-invasive, possibly curative intervention for these patients, which consist of a single stereotactic radiotherapy (SRT) treatment.

Objective: In the era of image-guided adaptive radiotherapy, definition of the clinical target volume (CTV) is a challenge in various solid tumors, including esophageal cancer (EC). Many tumor microenvironmental factors, e.g.

Aorta pathology and pregnancy-related risks in adult congenital cardiac disease: does the aorta dilate during pregnancy?

Background: Aortic dilatation and pregnancy are major concerns in women with aortopathy (AOP). This single-centre retrospective analysis focuses on the evolution of aortic diameters during and after pregnancy in women with Marfan syndrome (MS), Turner syndrome (TS) and bicuspid aortic valve (BAV) aortopathy.

Methods And Results: Thirty-eight women who had one or more single pregnancies were included.

Towards a European prospective data registry for particle therapy.

The evidence for the value of particle therapy (PT) is still sparse. While randomized trials remain a cornerstone for robust comparisons with photon-based radiotherapy, data registries collecting real-world data can play a crucial role in building evidence for new developments. This Perspective describes how the European Particle Therapy Network (EPTN) is actively working on establishing a prospective data registry encompassing all patients undergoing PT in European centers.

Radiomics for residual tumour detection and prognosis in newly diagnosed glioblastoma based on postoperative [C] methionine PET and T1c-w MRI.

Personalized treatment strategies based on non-invasive biomarkers have potential to improve patient management in patients with newly diagnosed glioblastoma (GBM). The residual tumour burden after surgery in GBM patients is a prognostic imaging biomarker. However, in clinical patient management, its assessment is a manual and time-consuming process that is at risk of inter-rater variability.

Tumour response to hypoxia: understanding the hypoxic tumour microenvironment to improve treatment outcome in solid tumours.

Hypoxia is a common feature of solid tumours affecting their biology and response to therapy. One of the main transcription factors activated by hypoxia is hypoxia-inducible factor (HIF), which regulates the expression of genes involved in various aspects of tumourigenesis including proliferative capacity, angiogenesis, immune evasion, metabolic reprogramming, extracellular matrix (ECM) remodelling, and cell migration. This can negatively impact patient outcomes by inducing therapeutic resistance.

Characterizing food environments of hospitals and long-term care facilities in the Netherlands: a mixed methods approach.

Background: Hospitals and long-term care facilities, which are key institutions to serve health and well-being, have an important exemplary role in providing supportive food environments to encourage healthy and sustainable food choices. The objective of this study is to characterize the physical, socio-cultural, political and economic dimensions of the food environment for health care receivers, health workforce and visitors in healthcare settings, and make comparisons between the food environment of hospitals and long-term care facilities.

Methods: To characterize the food environment in healthcare settings, two sub-studies were conducted.

Left atrial strain in patients after arterial switch operation for transposition of the great arteries.

Background: Left atrial (LA) strain, comprising LA reservoir, conduit and contractile function could add mechanistic information of patients after arterial switch operation (ASO) for transposition of the great arteries (TGA). ASO patients might have abnormal ventriculoarterial coupling, which makes them vulnerable to left ventricle (LV) dysfunction and results in reduced exercise capacity. This explorative study aimed to evaluate the relation between LA strain, atrial size, ventricular function, and exercise data obtained by cardiopulmonary exercise testing (CPET).

Biomarkers in transposition of the great arteries after arterial switch operation: A pilot trial with deep phenotyping.

Introduction: Transposition of the great arteries (TGA) is a cyanotic congenital heart defect for which the arterial switch operation (ASO) is the preferred surgical repair. This study wanted to investigate whether a panel of biomarkers could identify morphologic as well as hemodynamic changes obtained by cardiac magnetic resonance (CMR).

Methods: Forty-four adult patients were included.

Prediction of radiation pneumonitis using the effective α/β of lungs and heart in NSCLC patients treated with proton beam therapy.

Purpose: Radiation pneumonitis (RP) remains a major complication in non-small cell lung cancer (NSCLC) patients undergoing radiochemotherapy (RCHT). Traditionally, the mean lung dose (MLD) and the volume of the total lung receiving at least 20 Gy (V) are used to predict RP in patients treated with normo-fractionated photon therapy. However, other models, including the actual dose-distribution in the lungs using the effective α/β model or a combination of radiation doses to the lungs and heart, have been proposed for predicting RP.

Multitask Learning with Convolutional Neural Networks and Vision Transformers Can Improve Outcome Prediction for Head and Neck Cancer Patients.

Neural-network-based outcome predictions may enable further treatment personalization of patients with head and neck cancer. The development of neural networks can prove challenging when a limited number of cases is available. Therefore, we investigated whether multitask learning strategies, implemented through the simultaneous optimization of two distinct outcome objectives (multi-outcome) and combined with a tumor segmentation task, can lead to improved performance of convolutional neural networks (CNNs) and vision transformers (ViTs).

A Phase 1 Study of the DNA-PK Inhibitor Peposertib in Combination With Radiation Therapy With or Without Cisplatin in Patients With Advanced Head and Neck Tumors.

Purpose: DNA-dependent protein kinase (DNA-PK) plays a key role in the repair of DNA double strand breaks via nonhomologous end joining. Inhibition of DNA-PK can enhance the effect of DNA double strand break inducing anticancer therapies. Peposertib (formerly "M3814") is an orally administered, potent, and selective small molecule DNA-PK inhibitor that has demonstrated radiosensitizing and antitumor activity in xenograft models and was well-tolerated in monotherapy.
