Lysteria Monocytogenes Infection during Monochorionic Twin Pregnancy: Case Report and Review of the Literature.

Listeriosis is a rare but severe foodborne disease caused by (LM), a small facultative intracellular bacillus. When occurring in pregnant women, it can be vertically transmitted to the fetus and the newborn. Infected women usually display aspecific and mild symptoms, and rarely develop the severe forms of the disease (such as neurolisteriosis).

Maternal Circulating Vitamin D Level, Targeted Supplementation, and Perinatal Outcomes in Twin Pregnancy.

Background: Vitamin D deficiency is associated with several obstetric complications in singleton pregnancy. The aim of this study was to assess whether vitamin D levels affect the outcomes of twin pregnancy and if targeted supplementation can improve perinatal outcomes.

Methods: The serum vitamin D levels of 143 women with twin pregnancies were measured during their first trimester.

Retrospective comparison of monochorionic diamniotic twin pregnancies stratified by spontaneous or artificial conception.

Objectives: To compare outcomes of monochorionic diamniotic (MCDA) twin pregnancies by fertilization (IVF) vs. spontaneously conceived counterparts.

Methods: Retrospective comparison.

Gestational Diabetes Mellitus Does Not Worsen Obstetrical and Neonatal Outcomes of Twin Pregnancy.

The specific effects of gestational diabetes mellitus (GDM) on twin pregnancy outcomes, which are at high risk per se, are unclear. The present study analyzes outcomes of twin pregnancies complicated by GDM (n = 227) by comparing them with GDM singleton pregnancies (n = 1060) and with twin pregnancies without GDM (n = 1008), all followed up at Sant'Anna Hospital, Turin (Italy), between January 2010 and March 2020. The prevalence of GDM among twin pregnancies (n = 1235) was 18.
