Introduction: Treatment with Sunitinib, a potent multitargeted receptor tyrosine kinase inhibitor (TKI) has increased the progression-free survival (PFS) and overall-survival (OS) of patients with metastasized renal cell carcinoma (mRCC). With modest OS improvement and variable response and toxicity predictive and/or prognostic biomarkers are needed to personalize patient management: Prediction of individual TKI therapy response and resistance will increase successful treatment outcome while reducing unnecessary drug use and expense. The aim of this study was to investigate whether kinase activity analysis can predict sunitinib response and/or toxicity using tissue samples obtained from primary clear cell RCC (ccRCC) from a cohort of clinically annotated patients with mRCC receiving sunitinib as first-line treatment.

Hypertension and orthostatic hypotension in the elderly: a challenging balance.

Lancet Reg Health Eur

January 2025

Department of Internal Medicine, Section Geriatrics, Amsterdam UMC, Boelelaan 1117, Amsterdam, the Netherlands.

Hypertension and orthostatic hypotension (OH) frequently coexist in the older population, both stemming from impaired blood pressure (BP) regulation. Managing hypertension in patients with OH presents a significant clinical challenge, particularly in frail older adults who are also prone to falls. Hypertension treatment is often suboptimal in this population due to concerns over the potential increased risk of falls associated with treatment.

Monitoring and modulating cardiac bioelectricity: from Einthoven to end-user.

Europace

December 2024

Laboratory of Experimental Cardiology, Department of Cardiology, Leiden University Medical Center, Albinusdreef 2, Leiden 2333 ZA, The Netherlands.

In 2024, we celebrate the 100th anniversary of Willem Einthoven receiving the Nobel Prize for his discovery of the mechanism of the electrocardiogram (ECG). Building on Einthoven's legacy, electrocardiography allows the monitoring of cardiac bioelectricity through solutions to the so-called forward and inverse problems. These solutions link local cardiac electrical signals with the morphology of the ECG, offering a reversible connection between the heart's electrical activity and its representation on the body surface.

Unlabelled: Children with Noonan syndrome-like RASopathies are at increased risk for developing feeding problems due to comorbid organic impairments at an early age, such as gastrointestinal problems or other organicity. Their feeding problems can ultimately often be classified as avoidant/restrictive food intake disorder, for which behavioral therapy is the first-choice treatment. The research question in this study is whether this treatment leads to similar results as in children without these RASopathies.

Incorporation of ionizable lipids into the outer shell of lipid-coated calcium phosphate nanoparticles boosts cellular mRNA delivery.

Int J Pharm

December 2024

Department of Medical BioSciences, Radboud University Medical Center, The Netherlands; Department of Medical Biochemistry, College of Medicine and Medical Sciences, Arabian Gulf University, Manama 329, Bahrain. Electronic address:

Messenger RNA is a highly promising biotherapeutic modality with great potential in preventive and therapeutic vaccination, and in the modulation of cellular function through transient expression of therapeutic proteins. However, for cellular delivery, mRNA requires packaging into delivery vehicles that mediate uptake and also shield the mRNA against degradation. Lipid-coated calcium phosphate (LCP) nanoparticles encapsulate the mRNA in a calcium phosphate core, which is coated by a bilayer of structural lipids, positively charged lipids and pegylated lipid to mediate cellular uptake and achieve colloidal stabilization.
