BACKGROUND: Patient records, imaging, and residual biomaterial from clinical procedures are crucial resources for medical research. In the Netherlands, consent for secondary research has historically relied on opt-out consent. For ethical-legal experts who purport passive consent undermines patient autonomy, opt-in consent (wherein affirmative action is required) is seen as the preferred standard. To date, there is little empirical research exploring patient feasibility, organizational consequences, and the potential risks for research based on secondary data...

BACKGROUND: In Indonesia, drug resistance testing for TB largely relies on Xpert MTB/RIF, and it is unknown what proportion of drug-resistant (DR) TB is adequately diagnosed and treated. METHODS: We conducted a cascade of care analysis on a cohort of presumptive rifampicin-resistant (RR) TB patients registered in 2015-2018 in a tertiary hospital in Indonesia. Estimated incidences of (presumptive) DR-TB cases were assumption-based using global reports. Data on diagnosis and consecutive cascades steps, including their timing were collected from national electronic registers, and medical records...

PATIENTS: All patients with a chronically discharging mastoid cavity surgically treated at the Radboud University Medical Center by STP or CWR-BOT in 2015 to 2020, excluding patients with preoperative cholesteatoma...

OBJECTIVE: The Cleft Aesthetic Rating Scale (CARS) is a valid tool to assess the aesthetic outcome after unilateral cleft lip and palate (UCLP) repair. The goal of this study was to investigate whether the reliability of CARS increases by including fixed rates for atypical outcomes such as a smaller nostril, lower vermillion border or whistling deformity. DESIGN: 197 patients with UCLP who underwent cleft repair were included. Three cleft experts rated the post-operative photos using the original CARS, followed by a second assessment employing the modified CARS...

AIMS: Kleefstra syndrome (KS), often diagnosed in early childhood, is a rare genetic disorder due to haploinsufficiency of EHMT1 and is characterized by neuromuscular and intellectual developmental abnormalities. Although congenital heart disease (CHD) is common, the prevalence of arrhythmias and CHD subtypes in KS is unknown. METHODS AND RESULTS: Inspired by a novel case series of KS patients with atrial tachyarrhythmias in the USA, we evaluate the two largest known KS registries for arrhythmias and CHD: Radboudumc (50 patients) based on health record review at Radboud University Medical Center in the Netherlands and GenIDA (163 patients) based on worldwide surveys of patient families...

OBJECTIVE: To enhance evidence-based knowledge on long-term sequalae in patients with surgically corrected obstructing Müllerian anomalies. METHODS: This long-term case-control study included patients with menstrual outflow obstruction due to congenital anomalies of the uterus or vagina, who were at least 18 years old, and for whom 2 years had elapsed since the first surgery at the start of this study. The control group consisted of women without current gynecological problems...

BACKGROUND: Shortening of the long finger flexors (Flexor Digitorum Profundus, FDPs) in Duchenne Muscular Dystrophy (DMD) causes reduced hand function. Until now, longitudinal studies on the natural course of the shortening of the FDPs are lacking, which impedes recommendations on timing and evaluation of preventive measures. OBJECTIVE: To investigate the longitudinal course of the FDP length during different disease stages focusing on symmetry, timing, and decline of the FDP length...

IgG antibodies are important mediators of vaccine-induced immunity through complement- and Fc receptor-dependent effector functions. Both are influenced by the composition of the conserved N -linked glycan located in the IgG Fc domain. Here, we compared the anti-Spike (S) IgG1 Fc glycosylation profiles in response to mRNA, adenoviral, and protein-based COVID-19 vaccines by mass spectrometry (MS). All vaccines induced a transient increase of antigen-specific IgG1 Fc galactosylation and sialylation. An initial, transient increase of afucosylated IgG was induced by membrane-encoding S protein formulations...

OBJECTIVES: To evaluate the influence of miniscrew-assisted rapid palatal expansion (MARPE) on the interdental papilla height of maxillary central incisors. MATERIALS AND METHODS: Patients who completed MARPE treatment at the Radboud University Medical Center between 2018 and 2021 were included in this retrospective study. The papilla height between the maxillary central incisors was evaluated on frontal intraoral photographs taken before expansion (T0) and 1.5 years after MARPE treatment (T1) using the Jemt classification...
