Purpose: The aim of our study was to investigate to what degree clinical characteristics can contribute to incidence and structure of pregnancy and childbirth complications in women with diabetes, and to reveal key risk factors for adverse outcomes.

Methods: We conducted a retrospective single-center cohort study from January 2008 through December 2017, including 3069 singleton pregnancies, affected by type 1 diabetes (T1D, n = 498), type 2 diabetes (T2D, n = 214), and gestational diabetes mellitus (GDM, n = 2357).

Results: More than 10 years duration of T1D associated with increased risk for preterm birth (RR 2.

Purpose: To evaluate the level of soluble endoglin (sEng) in pregnant women with pregestational diabetes mellitus (DM) and to assess its predictive value for preeclampsia development.

Methods: Ninety pregnant women were enrolled in the study forming five comparison groups: type 1 DM (not planned, n = 20; planned, n = 20), type 2 DM (diet, n = 15; insulin therapy, n = 20), and the control group (n = 15). The primary outcome was clinically confirmed preeclampsia.

Objective: To evaluate a level of expression of endoglin (Eng), leptin (Lep), placental growth factor (PlGF), and hypoxia-inducible factor-1alpha (HIF-1α) in placenta among women with pre-eclampsia and diabetes mellitus (DM), considering the method of glycemia correction and preconception care.

Materials And Methods: A retrospective cohort study was conducted. A total of 124 women were divided into following groups: type 1 DM ( = 40), type 2DM ( = 31), gestational DM ( = 33), pre-eclampsia without DM (PE) ( = 10) and the control group ( = 10).

The review presents some renewed data on the problem of optimal time and modes of delivery for women with various types of diabetes mellitus (DM 1 and 2, gestational diabetes). The necessity of making the universal delivery strategy algorithm for women with DM comes out of adverse outcomes high frequency, where the main cases are fetal macrosomia, fetal shoulder dystocia and perinatal mortality. Despite significant interest for this issue, there is still no common delivery tactics in the world for pregnant women with carbohydrate metabolism disorders.

Objective: To evaluate serum concentration of 8-isoprostane, nitrotyrosine (NT), and total antioxidant capacity (TAC) in pregnant women with diabetes mellitus (DM) considering preconception planning and method of diabetes correction in 11-14 and 30-34 weeks.

Materials And Methods: The study included 130 women: T1DM (n = 40), T2DM (n = 35), gestational diabetes (GDM, n = 40) and the control group (n = 15). The serum concentrations of NT, 8-isoprostane, and TAC were measured by ELISA methods.

Objective: Evaluation of serum concentration of leptin, adiponectin, resistin, and MCP-1 in pregnant patients with different types of diabetes mellitus (DM) considering preconception planning and method of DM correction in 11-14th and 30-34th weeks of pregnancy.

Study Design: Longitudinal, prospective study included 130 pregnant women divided into the following comparison groups: type 1 DM (T1DM, n = 40), type 2 DM (T2DM, n = 35), GDM (n = 40), and the control group (n = 15). The ELISA method defined the levels of leptin, resistin, adiponectin, and MCP-1 concentration in serum, which was assessed in 11-14th and 30-34th weeks of pregnancy.

Objective: Immunotherapy of tuberculosis (TB) to shorten treatment duration represents an unmet medical need. Orally delivered, tableted TB vaccine (V7) containing heat-killed (NCTC 11659) has been demonstrated in prior clinical studies to be safe and fast-acting immune adjunct.

Methods: The outcome of Phase III trial of V7 containing 10 µg of hydrolyzed was evaluated in 152 patients randomized at 2:1 ratio: V7 ( = 100), placebo ( = 52).

Background: Pre-eclampsia is the most common complication occurring during pregnancy. In the majority of cases, it is concurrent with other pathologies in a comorbid manner (frequent co-occurrences in patients), such as diabetes mellitus, gestational diabetes and obesity. Providing bronchial asthma, pulmonary tuberculosis, certain neurodegenerative diseases and cancers as examples, we have shown previously that pairs of inversely comorbid pathologies (rare co-occurrences in patients) are more closely related to each other at the molecular genetic level compared with randomly generated pairs of diseases.
