However, one‐fifth of IOLs result in Cesarean section (CS). We aimed to assess maternal and fetal characteristics that influence the likelihood of CS following IOL, according to the indication for CS.MethodsThis was a secondary analysis of pooled data from four randomized controlled trials, including women undergoing IOL at term who had a singleton pregnancy and an unfavorable cervix, intact membranes and the fetus in cephalic presentation. The main outcomes of this analysis were CS for failure to progress (FTP) and CS for suspected fetal compromise (SFC). Restricted cubic splines were used to determine whether continuous maternal and fetal characteristics had a non‐linear relationship with outcome. Optimal cut‐offs for those characteristics with a non‐linear pattern were determined based on the maximum area under the receiver‐operating‐characteristics curve. Adjusted odds ratios (aOR) ...

Condition being studied: Women with an untreated, histologically proven, CIN2-3 lesion or women who were persistent high-risk HPV positive. Eligibility criteria: Studies that evaluated the efficacy of imiquimod treatment in intraepithelial lesions or malignancy of other organs, and studies published as conference abstract, narrative review, editorial, letter, or short communication were excluded.

Objectives To determine the efficacy of topical imiquimod in treatment of high-grade CIN (defined as regression CIN 1 or less), and to determine the clearance rate of high-risk human papillomavirus (hr-HPV), compared to surgical treatment and placebo. Search strategy Cohort studies and trials up to July 2022 were searched with the terms imiquimod, cervical dysplasia, and HPV. Selection criteria Studies evaluating the efficacy of imiquimod in CIN lesions. Data collection and analysis The study followed the PRISMA checklist. Meta-analysis was conducted to determine the efficacy of imiquimod treatment. Main results Five studies involving 463 women with high-grade CIN were included. Imiquimod was associated with histological regression to CIN1 or less in 55% of cases versus 29% for placebo, and 93% for su...

MATERIALS & METHODS This retrospective multicentre cohort study included 198 women with VM treated in eight cancer centres in the Netherlands and UK between 1990 and 2017. Clinicopathological features, treatment, recurrence, and survival data were collected. Overall and recurrence-free survival was estimated with the Kaplan-Meier method. Prognostic parameters were identified with multivariable Cox regression analysis. RESULTS The majority of patients (75.8%) had localized disease at diagnosis. VM was significantly associated with high-risk clinicopathological features, including age, tumour thickness, ulceration, positive resection margins and involved lymph nodes. Overall survival was 48% (95% CI 40-56%) and 31% (95% CI 23-39%) after 2 and 5 years respectively and did not improve in patients diagnosed after 2010 compared to p...

Patients diagnosed with early-stage cervical cancer have a good prognosis, however, 10-20% suffer from local or distant recurrent disease after primary treatment. Treatment options for recurrent cervical cancer are limited. Therefore, it is crucial to identify factors that can predict patients with an increased risk of recurrence to optimize treatment to prevent the recurrence of cervical cancer. We aimed to identify biomarkers in early-stage primary cervical cancer which recurred after surgery. Formalin-Fixed, Paraffin-Embedded surgical specimens of 34 patients with early-stage cervical cancer (FIGO 2009 stage 1B1) and 7 healthy controls were analyzed. Targeted gene expression profiling using the PanCancer IO 360 panel of NanoString Technology was performed. The findings were confirmed by performing immunohistochemistry stainings. Various genes, namely GLS, CD36, WNT5a, HRAS, DDB2, PIK3R2, and CDH2 were found to ...

DESIGN : Multicentre, randomised, open-label trial in 12 hospitals in the Netherlands between February 2009 and May 2010. METHODS : Women scheduled for induction of labour at full term singleton pregnancy in cephalic presentation, intact membranes, and an unripe cervix (Bishop score < 6) were enrolled by means of an on-line system. Participants were randomly allocated to induction of labour with a transcervical Foley catheter or vaginal prostaglandin E2 gel. The primary outcome was caesarean section rate. Secondary outcomes were maternal and neonatal morbidity and time from induction to birth. RESULTS : A total of 824 women were allocated to induction of labour with a Foley catheter (n = 412) or prostaglandin E2 (n = 412). Caesarean section rates were comparable (23% versus 20%, RR 1.13, 95% CI 0.87 to 1.47). In the...

Using an ovine model of endotoxin-induced brain injury we have recently shown that recombinant human erythropoietin (rhEPO) reduces brain injury and protects against damage to myelination in major myelinated axon tracts. Our present objective was to determine whether rhEPO is also protective of the placenta and the fetal liver, organs which could influence fetal well-being. At 107 +/- 1 days of gestational age (DGA) chronically catheterized fetal sheep were randomly assigned to receive, on 3 consecutive days, either: 1) an i.v. bolus dose of lipopolysaccharide (LPS; approximately 0.9 microg/kg; n = 8); 2) i.v. bolus dose of LPS, followed at 1 h by 5000 IU/kg of rhEPO (LPS + rhEPO, n = 8); 3) rhEPO (n = 3). Seven untreated fetuses served as controls (n = 7). The placenta and fetal liver were examined histologically at 116 +/- 1 DGA; a placental injury index was formulated comprising measures of placental area, apoptosis, tissue injury and the size of the intervillous space. In LPS-exposed fetuses this index was greater than in control or rhEPO alone fetuses (p &amp;amp;lt; 0.02). Treatment of LPS-exposed fetuses with rhEPO resulted in a reduction in the index (p &amp;amp;lt; 0.05) and in the extent of liver necrosis. We conclude that rhEPO offers protection to the placenta and fetal liver in the presence of acute inflammation.
