Increased doses of vaginal progesterone for the prevention of preterm birth in twin pregnancies: a randomised controlled double-blind multicentre tri…

2012

Objective  Previous trials have shown little benefit for preventing preterm birth in twin pregnancies using 90–200 mg of daily vaginal natural progesterone. Higher doses have not been tested. Our aim was to determine the efficacy and safety of two different daily doses of vaginal natural progesterone (200 and 400 mg), compared with placebo, for preventing preterm birth in unselected twin pregnancies. Design  Randomised controlled double-blind multicentre trial (1:1:1). Setting  The study was carried out in five university centres from Valencia, Murcia and Alicante (Spain). Population  Women with dichorionic diamniotic twin pregnancies. Methods  The women self-inserted two vaginal pessaries …

CLINICAL IMPACT OF MATERNAL-EMBRYONIC COMMUNICATION AT IMPLANTATION

2019

The endometrium is a hormonally regulated organ that is non-adhesive to embryos throughout most of the menstrual cycle in humans. Endometrial receptivity refers to a hormone-limited period in which the endometrial tissue acquires a functional and transient ovarian steroid-dependent status allowing blastocyst adhesion. Functional genomic studies of human endometrium in natural cycles have demonstrated that endometrial receptivity is an active process involving up- and down-regulation of hundreds of genes ( 1 ). Personalized medicine is a well-accepted concept in reproductive medicine except for the endometrial factor that is still neglected. Our group has developed the endometrial receptivit…

Prä- und postnatales Nierenscreening im Vergleich: eine Analyse von 34.450 Neugeborenen des Geburtenregisters Mainzer Modell

2002

Zielsetzung. Fehlbildungen des internen Urogenitalsystems sind haufig und stellen die zweithaufigste Organkategorie dar. Anhand des Mainzer Geburtenregisters werden populationsbezogene Pravalenzen von Nierenfehlbildungen, die Sensitivitat des pranatalen Ultraschalls und die Haufigkeit operationsbedurftiger Befunde ermittelt. Material und Methode. Im Zeitraum von 1990–2001 erhielten alle in Mainz geborenen Kinder neben einer klinischen Untersuchung eine Ultraschalluntersuchung der ableitenden Harnwege. Bei Totgeborenen, Spontanaborten (≥15. SSW) und induzierten Aborten wurden die Befunde der Pathologie in die Erfassung einbezogen. Seit 1996 (nach Einfuhrung des Fehlbildungsschalles in die Mu…

Características de los recién nacidos tras fecundación in vitro

2009

Resumen: Objetivo: determinar en una unidad neonatal de nivel II la frecuencia de nacimientos tras fecundación in vitro (FIV) incluyendo FIV-ICSI (intracytoplasmic sperm injection) y comparar sus características con los de fecundación natural (FN), según sean gemelares o únicos. Pacientes y método: estudio prospectivo mediante revisiones fetales desde la semana 12 de gestación tras FIV, al nacer y al año de vida. Del 1 de enero de 2004 al 31 de marzo de 2007 nacieron 7.008 recién nacidos (RN), 113 tras FIV y 6.895 por FN. Resultados: la gemelaridad es del 2,4% en FN y el 56,6% en FIV (p<0,001). La edad materna media en únicos es 28±9 años en FN y 36±4 en FIV (p<0,05); en gemelares es 29±10 …

Facilitators and barriers HPV unvaccinated girls after 5 years of program implementation

2014

Understanding perceptions and characteristics of human papillomavirus (HPV) vaccinated and non-vaccinated girls can inform communication activities and vaccine delivery strategies. The purpose of this study was to evaluate knowledge and factors associated with HPV unvaccinated girls after five years of vaccination program implementation in Sicily, an Italian region with low vaccination coverage (<50.0%). A cross-sectional study was conducted through a questionnaire designed to assess knowledge and vaccination status of girls of 1997, 1998, 1999, and 2000 birth cohorts. The sample consisted of 350 girls who attended three high schools. Multivariable logistic regression analysis was conducted…

Influence of the Urban Exposome on Birth Weight

2019

Background: The exposome is defined as the totality of environmental exposures from conception onwards. It calls for providing a holistic view of environmental exposures and their effects on human health by evaluating multiple environmental exposures simultaneously during critical periods of life. Objective: We evaluated the association of the urban exposome with birth weight. Methods: We estimated exposure to the urban exposome, including the built environment, air pollution, road traffic noise, meteorology, natural space, and road traffic (corresponding to 24 environmental indicators and 60 exposures) for nearly 32,000 pregnant women from six European birth cohorts. To evaluate associatio…

Key indicators and information systems for the evaluation and planning of birthing hospital services

2016

The evaluation, monitoring and management of hospital of birth services requires the availability of a set of information and tools able to orient decision making process, in order to ensure an adequate level of quality of services provided. Given the complexity of birth-related services, a set of indicators related with the multiple dimensions of healthcare quality are required; these include: volume of activity, complexity of birth, territorial distribution and residents-hospital distance, infrastructures, and inter-hospital transfers. The present Paper proposes an integrated system of indicators for the promotion and improvement of birth-related services in the Sicily region, which takes…

Genetic syndrome suspicion: examples of clinical approach in the neonatal unit.

2010

Overgrowth syndromes: the practical clinical approach. Excessive growth can be present in a variety of medical conditions as result of abnormal fetal metabolism (i.e., maternal gestational diabetes) or of an overgrowth syndrome. Within this latter group of diseases, a LGA newborn requires a complex differential diagnosis encompassing several syndromes, such as Beckwith-Wiedemman, Sotos, Weaver, Simpson-Golabi-Behmel, Perlman, and Bannayan-Riley-Ruvalcaba. Partial or global overgrowth, other dysmorphisms, abdominal organs anomalies, as well as benign and malignant tumors are the common issues to examine for the diagnosis and the monitoring of all these disorders. The molecular bases of these…

Second trimester uterine arteries pulsatility index is a function of placental pathology and provides insights on stillbirth aetiology: A multicenter…

2022

Introduction: The aim of this study was to investigate the relationships between maternal vascular malperfusions (MVM) and second trimester uterine arteries pulsatility index (UtA-PI) in cases of stillbirth (SB), compared to live-birth (LB) matched controls. Methods: This was a multicentre, observational, matched case-control study performed at five referral maternity centres over a 4-year period including SB and LB control pregnancies at high-risk for preeclampsia (PE) and/or fetal growth restriction (FGR), matched and stratified for UtA-PI MoM quartiles values of the SB cases. Logistic regression was used to assess the rates of each MVM finding, within each increasing MoM quartile subcate…
