The influence of bacterial vaginosis on gestational week of the completion of delivery and biochemical markers of inflammation in the serum.

Background/aim: Preterm delivery is one of the most common complications in pregnancy, and it is the major cause (75-80%) of all neonatal deaths. Bacterial vaginosis predisposes to an increased risk of preterm delivery, premature rupture of membrane and miscarriage. In this syndrome normal vaginal lactobacilli, which produce protective H2O2, are reduced and replaced with anaerobic, gram-negative bacteria and others.

Comparison of the tissue penetration and glide force of 22-gauge thin-wall needles for intravitreal implant administration.

Background And Objective: To identify a needle to improve intravitreal dexamethasone implant administration by evaluating ease of ocular tissue penetration and glide force, key characteristics of needle performance.

Materials And Methods: Two custom-applicator needles coated with distinct lubricants (needles A and B) and the original dexamethasone implant needle were evaluated by five retina specialists. Ex vivo porcine eyes were injected, and a visual analog scale was used in ratings.
