Clinical conjunctivitis was significantly associated with the later study period, male gender and LOS. Conjunctival swab sampling increased significantly following the implementation of red reflex examinations, but without changes in the bacterial conjunctivitis rate and the bacterial growth percentage.

Intrapartum antibiotics are widely used and may potentially affect bilirubin levels and neurotoxicity in the newborn. The aim of this study was to examine the effect of intrapartum antibiotic exposure on neonatal jaundice. We retrospectively collected data from 972 neonates born to 963 mothers. Five hundred forty-five mothers (56.6%) received intrapartum antibiotics. There were no statistically significant differences in maximum bilirubin level (7.82 ± 3.65 vs 7.63 ± 3.71, P = .43) or need for phototherapy (9 [1.62%] vs 4 [0.94%], P = .52) between exposed and non-exposed newborns. The rate of phototherapy was significantly higher only in the group of infants born to mothers who received broad-spectrum antibiotics at 2 to 3.9 hours prior to delivery (χ2 = 10.453, P = .015) and was not higher in the group of exposure >4 hours, which may represent a short transient effect of antibiotics exposure on bilirubin turnover. Further studies are needed to validate this finding.

Objective. The purpose of the research was to study the effect of DNA methylation modulators on the production of proinflammatory cytokines by fibroblast-like synovial cells (FLC).Materials and methods. We used the cells derived from the synovial tissue of 6 patients with active rheumatoid arthritis (RA) after 3–7 in vitro culturing passages.Results. There was an IL-1β-induced up-regulation of osteoprotegerin (OPG) synthesis in the RA FLC cultures. The addition of methylating compounds S-Adenosyl methionine (SAMe) and genistein into the cultures resulted in a statistically significant decrease in the production of OPG, while the addition of the demethylating agent hydralazine did not change the synthesis of the cytokine. All three DNA methylation modulators used at different concentrations significantly reduced the percentage of spontaneous migration and invasion of FLC in the Boyden chamber.Conclusion. Enzymes and molecular complexes involved in DNA methylation could be potential therapeutic targets, and in vitro FLC cultures of RA patients can be used as a model for preclinical screening of new drug compounds.
