Introduction: Central to targeted radionuclide imaging and therapy of prostate cancer (PCa) are prostate-specific membrane antigen (PSMA)-targeting radiopharmaceuticals. Gastrin-releasing peptide receptor (GRPR) targeting has been proposed as a potential additional approach for PCa theranostics. The aim of this study was to investigate to what extent and at what stage of the disease GRPR-targeting applications can complement PSMA-targeting theranostics in the management of PCa.

Image-guided surgery using a gastrin-releasing peptide receptor (GRPR)-targeting dual-modality probe could improve the accuracy of the resection of various solid tumors. The aim of this study was to further characterize our four previously developed GRPR-targeting dual-modality probes that vary in linker structures and were labeled with indium-111 and sulfo-cyanine 5. Cell uptake studies with GRPR-positive PC-3 cells and GRPR-negative NCI-H69 cells confirmed receptor specificity.

Purpose: The radiolabeled gastrin-releasing peptide receptor (GRPR)-targeting antagonist NeoB is a promising radioligand for imaging and therapy of GRPR-expressing malignancies. In the current study, we aimed to discover the target organs of toxicity and the radiotoxic effects to these organs, when repeated dosages of [Lu]Lu-NeoB are administered to healthy female and male mice.

Methods: Animals received either 3 injections, with a 7-day interval, of vehicle (control group 1), 1200 pmol [Lu]Lu-NeoB (control group 2) or 40 MBq/400 pmol, 80 MBq/800 pmol, and 120 MBq/1200 pmol [Lu]Lu-NeoB (treatment groups 1, 2, and 3, respectively).

Nuclear and optical dual-modality probes can be of great assistance in prostate cancer localization, providing the means for both preoperative nuclear imaging and intraoperative surgical guidance. We developed a series of probes based on the backbone of the established GRPR-targeting radiotracer NeoB. The inverse electron demand of the Diels-Alder reaction was used to integrate the sulfo-cyanine 5 dye.

Background: The Ages and Stages Questionnaire Social-Emotional (ASQ-SE) is a parent-report screening instrument designed to assess children's social-emotional development and detect those at risk for delay or problems. Psychometric properties of this questionnaire have been studied before, but the ASQ-SE has never been compared to the Social-Emotional Scale of the Bayley-III (Bayley-III-SE).

Aim: To compare the Dutch ASQ-SE (ASQ-SE-NL) to the Dutch Bayley-III-SE (Bayley-III-NL-SE; criterion measure).

Moderately preterm born children (MPT) are at increased risk for behavior problems compared to full term born (FT) children. MPT children may receive less optimal parenting, and in response, may develop behavior problems. Our aims were to examine whether parenting behavior and mother-child interaction quality mediate the association between birth status and child behavior problems.

Language development in toddlerhood forms the foundation for speech and language comprehension throughout childhood. Children born moderately preterm are at increased risk for problems in receptive and expressive language functioning, and they may need specific support or interventions. To understand the underlying mechanisms of language development, an integrated model of gestational age, attention capacities, and maternal sensitivity was examined in relation to receptive and expressive language functioning in toddlerhood.

Attention problems hinder many children in their cognitive and social emotional development. Children at risk for developmental problems, like preterm born infants, are specifically known for attention difficulties. Early identification of attention difficulties is important for application of appropriate stimulation in trying to reduce further problems.

Objective: To compare moderate-to-late preterm born (32-36 weeks' gestation) to full term born (≥37 weeks' gestation) children in cognitive and behavioural functioning at the age of 6 years and assess which toddler skills predict later cognitive and behavioural functioning.

Design: A prospective longitudinal study with a cohort of 88 moderate-to-late preterm and 83 full term born Dutch children, followed from 18 months to 6 years of age. Orienting, alerting and executive attention skills were assessed at 18 months (corrected for prematurity), and cognitive, motor and language skills (Bayley-III-NL) at 24 months (corrected for prematurity).

Targeted therapies, such as radioimmunotherapy (RIT), present a promising treatment option for the eradication of tumor lesions. RIT has shown promising results especially for hematologic malignancies, but the therapeutic efficacy is limited by unfavorable tumor-to-background ratios resulting in high radiotoxicity. Pretargeting strategies can play an important role in addressing the high toxicity profile of RIT.

Why do many preterm children show delays in development? An integrated model of biological risk, children's capacities, and maternal stimulation was investigated in relation to cognitive functioning at toddler age. Participants were 200 Dutch children (gestational age = 32-41 weeks); 51% boys, 96% Dutch nationality, 71.5% highly educated mothers.

A number of studies have evaluated associations between parenting practices, adolescent self-control, and adolescent antisocial behavior. Yet, few studies have examined associations between these constructs in early childhood or examined the extent to which both maternal and paternal self-control shapes them. To address these gaps, the current study utilizes longitudinal data collected on a sample of 117 Dutch boys and their parents to investigate the across time interrelationships between parental self-control, ineffective parenting, child self-control, and child aggression.

Background: The Bayley Scales of Infant and Toddler Development-third edition (Bayley-III) are frequently used to assess early child development worldwide. However, the original standardization only included US children, and it is still unclear whether or not these norms are adequate for use in other populations. Recently, norms for the Dutch version of the Bayley-III (The Bayley-III-NL) were made.
