BACKGROUND: The efficacy of vaginal progesterone for preventing preterm birth and adverse perinatal outcomes in singleton gestations with a short cervix has been questioned after publication of the OPPTIMUM study. OBJECTIVE: To determine whether vaginal progesterone prevents preterm birth and improves perinatal outcomes in asymptomatic women with a singleton gestation and a midtrimester sonographic short cervix. DATA SOURCES: MEDLINE, EMBASE, LILACS, and CINAHL (from their inception to September 2017), Cochrane databases, bibliographies, and conference proceedings...

AIM: Patients with an ultra-short uterine cervix as a result of large conization, repeated conization or radical trachelectomy (RT), are at high risk of preterm premature rupture of the membrane, which leads to preterm birth. We have commenced performing transabdominal cerclage (TAC) of the uterine cervix for these patients. In this study, we examined the safety of TAC and its impact on pregnancy. METHODS: We have performed TAC in 11 patients before pregnancy: in six after large cervical operations, such as repeated conization; and in five for difficulties with cervical cerclage after RT...

BACKGROUND: Cerclage placed for a sonographically short cervix has been shown to reduce the risk of preterm delivery in women with a history of prior preterm birth. While short cervix is traditionally placed before viability, the threshold gestational age at which viability is achieved continues to decrease, and, as a result, a larger subset of women may be ineligible to receive this potentially beneficial procedure. OBJECTIVE: To evaluate the association between obstetric outcomes and perioperative complications after placement of an ultrasound-indicated cerclage at periviability compared to placement in the previable period...

BACKGROUND: Preterm birth is in quantity and in severity the most important topic in obstetric care in the developed world. Progestogens and cervical pessaries have been studied as potential preventive treatments with conflicting results. So far, no study has compared both treatments. METHODS/DESIGN: The Quadruple P study aims to compare the efficacy of vaginal progesterone and cervical pessary in the prevention of adverse perinatal outcome associated with preterm birth in asymptomatic women with a short cervix, in singleton and multiple pregnancies separately...

INTRODUCTION: Vaginal administration of micronized progesterone (utrogestan capsule, UG) reduces the risk of preterm birth (PTB) in asymptomatic women with a sonographic short cervix at mid-trimester or with a prior history of spontaneous PTB; however, its exact mechanisms remain unclear. We hypothesized that UG limits the inflammatory processes within the gestational tissues and the cervix. METHODS: Fetal membranes and villous tissues were obtained from normal term placentas from women with cesarean delivery before labor onset...

OBJECTIVE: A paucity of effective interventions exists for the prevention of preterm birth (PTB). Renewed interest has focused on cervical pessaries, which have the benefits of being inexpensive, nonsurgical, and easily inserted and removed. In this study, we aim to describe our experience with this device in a Canadian tertiary care centre. Primary outcomes were rates of spontaneous or iatrogenic PTB before 37, 34, and 28 weeks gestation in pregnancies complicated by short cervix treated with cervical pessary...

BACKGROUND: The aim of this paper was to evaluate the validity of tumor volume measurement using diffusion-weighted (DW) imaging in cervical cancer. METHODS: In this retrospective study, 22 patients, who underwent preoperative 3.0 T MR examinations with DW imaging were evaluated. Tumor volume measurement by oblique axial (short axis to the uterine cervix) T2-weighted imaging was performed by manually outlining the tumor on the monitor. The area of tumor in each slice was multiplied by the slice profile (slice thickness plus intersection gap), and the total tumor volume was calculated by summation of these obtained volumes...

OBJECTIVE: To determine whether various proteins in the cervicovaginal fluid (CVF) known to be involved in immune regulation, alone or in combination with clinical risk factors, can predict spontaneous preterm delivery (SPTD) in women with cervical insufficiency or a short cervix (≤25 mm). METHODS: This retrospective cohort study included 62 asymptomatic women with cervical insufficiency (n = 27) or an asymptomatic short cervix (n = 35) at 18-27 weeks. CVF swab samples were taken for assays of vitamin D binding protein (VDBP), interleukin (IL)-8, matrix metalloproteinases (MMP)-9, tissue inhibitor of metalloproteinases (TIMP)-1, and Dickkopf-related protein 3 (DKK3) before cervical examination, and maternal blood was collected for the determination of the C-reactive protein (CRP) level...

BACKGROUND: The efficacy of antenatal corticosteroid treatment for women with threatened preterm birth depends on timely administration within 7 days before delivery. We modelled the probability of delivery within 7 days of admission to hospital among women presenting with threatened preterm birth, using routinely collected clinical characteristics. METHODS: Data from the Canadian Perinatal Network (CPN) were used, 2005-11, including women admitted to hospital with preterm labour, preterm pre-labour rupture of membranes, short cervix without contractions, or dilated cervix or prolapsed membranes without contractions at preterm gestation...

Targeted drug delivery has received considerable attention due to its key role in improving therapeutic efficacy and reducing the side effects of anticancer drugs. Bleomycin (BLM) is an anticancer antibiotic with short half-life, low therapeutic and high side effects that limit its clinical applications. This study aims to evaluate the anticancer potential of folate-targeted liposomal bleomycin (FL-BLM) and its free-folate form (L-BLM) on two different cancer cell lines including human cervix carcinoma HeLa, and human breast carcinoma MCF-7 cells...
