Child outcomes after placement of a cervical pessary in women with a multiple pregnancy: A 4-year follow-up of the ProTWIN trial.

ABSTRACT: INTRODUCTION:The ProTWIN trial previously showed no beneficial effect of treatment with a cervical pessary vs usual care to prevent preterm birth in women with a multiple pregnancy. However, in women with a midtrimester short cervix (<38 mm), pessary did reduce the composite outcome of neonatal morbidity and mortality. This follow-up study evaluates the long-term outcomes of all children born to mothers who participated in the ProTWIN trial at 4 years of age. MATERIAL AND METHODS:Parents received the Ages and Stages Questionnaire, Strength and Difficulties Questionnaire and a health questionnaire. All questionnaires were reported separately and as a combined outcome (abnormal child outcome). A linear mixed effects model was used to adjust for correlated data in twins and correction for confounders was performed. In exploratory analysis, a composite outcome of death or survival with abnormal child outcome was used by combining extrapolated data on child outcome with survival data. All data were analyzed for the total group and the subgroup of women with midtrimester short cervix. RESULTS:Of the original 813 women of the ProTWIN trial, we approached 579, of whom 258 participated (45%) in follow-up. We received questionnaires of 514 children (281 pessary vs 233 control), with 119 children in the subgroup of women with midtrimester short cervix. An abnormal child outcome was found in 23% in the pessary group vs 16% in the control group (odds ratio 1.58; 95% confidence interval 0.94-2.65). In exploratory analysis with extrapolated data on child outcome (n = 815), no difference in abnormal child outcome was seen between the pessary and control group. In the subgroup of women with a short cervix (n = 268), this composite outcome indicated a favorable outcome for children born to mothers with pessary. CONCLUSIONS:In women with a multiple pregnancy, the use of a cervical pessary did not improve development, behavior or physical outcomes of the surviving children at age 4.

Project description:BackgroundPreterm birth is a major health problem and contributes to more than 50% of the overall perinatal mortality. Preterm birth has multiple risk factors including cervical incompetence and multiple pregnancy. Different management strategies have been tried to prevent preterm birth, including cervical cerclage. Cervical cerclage is an invasive technique that needs anaesthesia and may be associated with complications. Moreover, there is still controversy regarding the efficacy and the group of patients that could benefit from this operation. Cervical pessary has been tried as a simple, non-invasive alternative that might replace the above invasive cervical stitch operation to prevent preterm birth.ObjectivesTo evaluate the efficacy of cervical pessary for the prevention of preterm birth in women with risk factors for cervical incompetence.Search methodsWe searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 September 2012), Current Controlled Trials and the Australian New Zealand Clinical Trials Registry (1 September 2012).Selection criteriaWe selected all published and unpublished randomised clinical trials comparing the use of cervical pessary with cervical cerclage or expectant management for prevention of preterm birth. We did not include quasi-randomised trials. Cluster-randomised or cross-over trials were not eligible for inclusion.Data collection and analysisTwo review authors independently assessed trials for inclusion.Main resultsThe review included one randomised controlled trial. The study included 385 pregnant women with a short cervix of 25 mm or less who were between 18 to 22 weeks of pregnancy. The use of cervical pessary (192 women) was associated with a statistically significantly decrease in the incidence of spontaneous preterm birth less than 37 weeks' gestation compared with expectant management (22% versus 59 %; respectively, risk ratio (RR) 0.36, 95% confidence interval (CI) 0.27 to 0.49). Spontaneous preterm birth before 34 weeks was statistically significantly reduced in the pessary group (6% and 27% respectively, RR 0.24; 95% CI 0.13 to 0.43). Mean gestational age at delivery was 37.7 + 2 weeks in the pessary group and 34.9 + 4 weeks in the expectant group. Women in the pessary group used less tocolytics (RR 0.63; 95% CI 0.50 to 0.81) and corticosteroids (RR 0.66; 95% CI 0.54 to 0.81) than the expectant group. Vaginal discharge was more common in the pessary group (RR 2.18; 95% CI 1.87 to 2.54). Among the pessary group, 27 women needed pessary repositioning without removal and there was one case of pessary removal. Ninety-five per cent of women in the pessary group would recommend this intervention to other people. Neonatal paediatric care admission was reduced in the pessary group in comparison to the expectant group (RR 0.17; 95% CI 0.07 to 0.42).Authors' conclusionsThe review included only one well-designed randomised clinical trial that showed beneficial effect of cervical pessary in reducing preterm birth in women with a short cervix. There is a need for more trials in different settings (developed and developing countries), and with different risk factors including multiple pregnancy.

Project description:BACKGROUND:Stem-cell-based, tissue engineered transplants might offer new therapeutic options for patients, including children, with failing organs. The reported replacement of an adult airway using stem cells on a biological scaffold with good results at 6 months supports this view. We describe the case of a child who received a stem-cell-based tracheal replacement and report findings after 2 years of follow-up. METHODS:A 12-year-old boy was born with long-segment congenital tracheal stenosis and pulmonary sling. His airway had been maintained by metal stents, but, after failure, a cadaveric donor tracheal scaffold was decellularised. After a short course of granulocyte colony stimulating factor, bone marrow mesenchymal stem cells were retrieved preoperatively and seeded onto the scaffold, with patches of autologous epithelium. Topical human recombinant erythropoietin was applied to encourage angiogenesis, and transforming growth factor ? to support chondrogenesis. Intravenous human recombinant erythropoietin was continued postoperatively. Outcomes were survival, morbidity, endoscopic appearance, cytology and proteomics of brushings, and peripheral blood counts. FINDINGS:The graft revascularised within 1 week after surgery. A strong neutrophil response was noted locally for the first 8 weeks after surgery, which generated luminal DNA neutrophil extracellular traps. Cytological evidence of restoration of the epithelium was not evident until 1 year. The graft did not have biomechanical strength focally until 18 months, but the patient has not needed any medical intervention since then. 18 months after surgery, he had a normal chest CT scan and ventilation-perfusion scan and had grown 11 cm in height since the operation. At 2 years follow-up, he had a functional airway and had returned to school. INTERPRETATION:Follow-up of the first paediatric, stem-cell-based, tissue-engineered transplant shows potential for this technology but also highlights the need for further research. FUNDING:Great Ormond Street Hospital NHS Trust, The Royal Free Hampstead NHS Trust, University College Hospital NHS Foundation Trust, and Region of Tuscany.
