BACKGROUND Multimorbidity, defined as the coexistence of 2 or more chronic diseases, is a common phenomenon especially in older people. Numerous efforts to establish a standardized instrument to assess the level of multimorbidity have failed until now, and indices are primarily characterized by their high heterogeneity. Thus, the objective is to provide a(More)
OBJECTIVE To explore the relationship among markers of infection/inflammation in their association with retinopathy of prematurity (ROP). METHODS We studied clinical characteristics and 4 single nucleotide polymorphisms in infection/inflammation-associated genes in a group of 73 children with a gestational age<32 weeks. Forty-four children (60%) had ROP,(More)
OBJECTIVE Streptococcus agalactiae (group B Streptococcus) is an important cause of morbidity and mortality in newborn infants. So far, there have been no published data on the incidence, morbidity, and mortality of invasive neonatal group B Streptococcus infections in Germany. METHODS A prospective active surveillance study involving all of the pediatric(More)
The relationships among bronchopulmonary dysplasia (BPD), brain white matter damage (WMD) and cerebral palsy (CP) are far from simple. Apparently, BPD and WMD are not associated, while BPD and CP are. The most likely explanation for this paradox is that ultrasound imaging does not identify all the WMD that might lead to CP ('tip-of-the-iceberg effect'). We(More)
In a matched-pair study, we analyzed the association of a phenotypically relevant NQO1 polymorphism (C609T) with risk of secondary malignant neoplasms (SMN) after treatment for childhood acute lymphoblastic leukemia. Patients carrying a variant low-activity NQO1 allele had a significantly increased risk of developing a SMN. The observed effect was(More)
OBJECTIVE To explore whether and how population based data from a regional quality control programme can be used to investigate the hypothesis that small for gestational age (SGA) very low birthweight infants (VLBW, <1500 g) are at increased risk of death, severe intraventricular haemorrhage (IVH), and periventricular leucomalacia (PVL), but at decreased(More)
BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting 1% to 2% of the population and raising the risk of stroke 5-fold. Until recently, the only treatment choices for stroke prevention in patients with AF have been vitamin K antagonists (VKA) or antiplatelet drugs. With approval of novel oral anticoagulants (NOACs)(More)
OBJECTIVES To establish a multiplex amplification refractory mutation system (ARMS) in fluid and dried whole blood, and to perform a pilot study to examine the role for single-nucleotide polymorphisms (SNPs) of inflammation-associated genes (interleukin [IL]-1 and -10, tumor necrosis factor-alpha [TNFA], and toll-like receptor-4 [TLR4]) and their(More)
BACKGROUND Very low birth weight infants (< 1500 g) are at increased mortality risk. Data on the impact of NICU volume are sparse, in comparison with those on the level of care. We hypothesized that neonatal mortality would be higher in small NICUs (< 36 very low birth weight admissions per year) than in large NICUs, with adjustment for volume of the(More)
Cranial ultrasonography has been used to identify brain injury in preterm neonates for more than two decades. More recently, magnetic resonance imaging has been used to evaluate brain development and pathology in these infants. In this review we describe how well findings from these two imaging modalities agree with histology findings and(More)
