Long-term Follow-up of Preterm Infants Having Been Colonized With Extended Spectrum Beta-lactamase-producing Enterobacterales Over the First 6 Years of Life.

We performed a retrospective case-control cohort study following 146 preterm infants (≤32 weeks of gestation) who had been colonized with extended spectrum beta-lactamase producing Enterobacterales and compared them with 1:1 matched controls regarding rates of hospitalizations and outpatient visits because of infectious and gastrointestinal diseases and developmental impairment up to school age. Preterm infants with extended spectrum beta-lactamase producing Enterobacterales colonization did have neither higher rates of gastrointestinal or infectious diseases nor higher rates of developmental impairments up to the age of 6 years.

Upregulated monocyte expression of PLIN2 is associated with early arterial injury in children with overweight/obesity.

Background And Aims: Perilipin 2 (PLIN2) regulates intracellular lipid metabolism in macrophages, and thus, plays a role in atherosclerosis. Aim of the study was to evaluate whether PLIN2 dysregulation is involved in the onset of preclinical atherosclerosis in children with overweight/obesity and to explore dysregulation mechanisms.

Methods: Sixty-three children with overweight/obesity and 21 normal weight children (controls) of the same age and sex were enrolled.

Carotid Extra-Media Thickness in Children: Relationships With Cardiometabolic Risk Factors and Endothelial Function.

Emerging evidence suggests that structural adventitial modifications and perivascular adipose tissue (PAT) may have a role in early atherogenesis. In a cohort of children and adolescents, we explored (1) the association of carotid extra-media thickness (cEMT), an ultrasound measure whose main determinants are arterial adventitia and PAT, with obesity and its cardiometabolic complications; and (2) the interplay between cEMT and endothelial function. The study participants included 286 youths (age, 6-16 years; 154 boys, and 132 girls).

Extended-spectrum beta-lactamase (ESBL) producing Enterobacterales in stool surveillance cultures of preterm infants are no risk factor for necrotizing enterocolitis: a retrospective case-control study over 12 years.

Purpose: Microbial dysbiosis has been found preceding necrotizing enterocolitis (NEC) in preterm infants; thus, we aimed to investigate whether there is evidence that neonates with extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E) positive stool cultures are at higher risk for NEC at the NICU.

Methods: We included very preterm inborn infants of ≤ 32 weeks of gestational age being fecal carriers of ESBL-E and compared them with 1:1 matched (gestational age, birth weight, gender and year) controls tested negative for ESBL-E in the stool between 2005 and 2016. An association with NEC was defined as the first detection of ESBL-E before or at the time of definite diagnosis of NEC.

The Role of Lipid and Lipoprotein Metabolism in Non-Alcoholic Fatty Liver Disease.

Due to the epidemic of obesity across the world, nonalcoholic fatty liver disease (NAFLD) has become one of the most prevalent chronic liver disorders in children and adolescents. NAFLD comprises a spectrum of fat-associated liver conditions that can result in end-stage liver disease and the need for liver transplantation. Simple steatosis, or fatty liver, occurs early in NAFLD and may progress to nonalcoholic steatohepatitis, fibrosis and cirrhosis with increased risk of hepatocellular carcinoma.
