Seasonal variation in the incidence of preterm births.

Objectives: To examine the influence of the season of conception, and the season of birth on the incidence of preterm birth (PTB) and neonatal outcomes.

Study Design: This is a single center, retrospective cohort study of singleton births that took place in The Coombe Hospital in Dublin, Ireland, between January 2013 and December 2022. A comprehensive database was analyzed to determine the incidence of PTB per season of conception and season of birth.

Trial of labour following two previous caesarean sections - A UK cohort study.

Objectives: To assess the (i) predictors of and associated rates of success and; (ii) maternal and perinatal outcomes of women undergoing trial of labour after two previous caesarean sections (TOLA2C).

Study Design: This retrospective cohort study collected data from two regional obstetric centres with 12,000 deliveries per annum collectively. The population included singleton pregnancies undergoing (i) TOLA2C, (ii) elective repeat caesarean section following two caesarean sections (ERCS) and (iii) trial of labour after one caesarean section (TOLA1C).

Homelessness in pregnancy.

Objectives: To evaluate the association, if any, of homelessness or refuge accommodation on delivery and short term perinatal outcomes in an Irish tertiary maternity hospital.

Methods: A retrospective cohort study of 133 singleton pregnancies in women reporting to be homeless or living in refuge at their booking antenatal appointment between 2013 and 2022. Analysis compared sociodemographic characteristics and perinatal outcomes in this cohort to a reference population of 76,858 women with stable living arrangements.

Perinatal and neonatal outcomes of high-risk asymptomatic women from a specialist preterm birth surveillance clinic.

Objectives: To report the perinatal outcomes of high-risk asymptomatic women who attended a specialist preterm surveillance clinic (PSC) to undergo screening for spontaneous preterm birth (PTB) in Ireland.

Methods: Single center, retrospective cohort study of asymptomatic high risk women who attended the PSC between January 2019 and December 2022. A comprehensive database of all patients who attended the clinic during the study period was constructed and analyzed.

Performance of QUiPP App v.2 tool for prediction of preterm birth in asymptomatic high-risk women attending preterm specialist clinic: external validation study.

Objective: To validate externally the QUiPP App v.2 algorithms in an independent cohort of high-risk asymptomatic women attending a preterm birth (PTB) surveillance clinic in Ireland.

Methods: This was a retrospective, single-center, observational study assessing discrimination and calibration of the QUiPP App v.
