Prematurity and twinning
2012
Aim of the study: Newborns from multiple pregnancies are increasing in number and demonstrate a higher perinatal morbidity and mortality compared to singletons. Prematurity is the main reason for most neonatal diseases in twins, but other variables may play a role and their prenatal evaluation may improve the overall outcome. Main findings: Prematurity is six times more frequent in twins and therefore birth weight is significantly lower compared to singletons. Thus, twins are more exposed to prematurity related diseases (respiratory, cardiovas- cular, infectious, etc.) and to long-term complications (especially neurological disabilities). Results: It is very difficult to estimate the increa…
Olfaction in the fetal and premature infant: functional status and clinical implications.
2004
This article considers olfaction as a functioning source of information for the fetus and the neonate, born on term or prematurely. It aims to present how odors are involved in the sensory continuity between the prenatal and postnatal environments and how they influence the earliest adaptive responses of newborns in the realms of self-regulation, emotional balance, feeding, and social interactions.Finally, it evaluates odors as sensory means to ameliorate the physiologic and behavioral responses of preterm infants to the adverse impacts of separation from mother, nonoral feeding, or iatrogenic distress.
Prevalence and characteristics of coronary artery disease in a population with suspected ischaemic heart disease using CT coronary angiography: corre…
2008
Purpose. This study was undertaken to describe the correlation between the distribution of coronary artery disease (CAD) in a symptomatic population with suspected ischaemic heart disease, cardiovascular risk factors (RF) and clinical presentation. Materials and methods. We studied 163 patients (mean age 65.5 years; 101 men and 62 women) referred for multidetector computed tomography coronary angiography (MDCT-CA) to rule out CAD. The patients had no prior history of revascularisation or myocardial infarction. We analysed how the characteristics of CAD (severity and type of plaque) can change with the increase in RF and how they are related to different clinical presentations. Results. Pati…

The role of physical activity in the link between menopausal status and mental well-being
2020
OBJECTIVE To examine the relationship between menopausal status and mental well-being, and whether this relationship varies as a function of physical activity (PA). METHODS Based on a hormonal analysis and bleeding diary, women aged 47 to 55 were categorized as pre (n = 304), early peri (n = 198), late peri (n = 209), or postmenopausal (n = 387). Mental well-being was assessed using the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule Short Form, and the Satisfaction with Life Scale. PA was self-reported and categorized as low, medium, and high. Associations between variables were analyzed using multivariate linear regression adjuste…
Probiotics Properties: A Focus on Pregnancy Outcomes.
2021
A healthy microbiome plays an important role in the prevention of illness and maintenance of overall health, including reproductive health. Although the therapeutic advantages of probiotics have been shown to run across multiple organ systems, their role in pregnancy is not well explored. The aim of this review is to highlight the potential advantages and adverse effects of probiotics in pregnancy. Data were collected from the literature over the past decade using PubMed, Medline, Google Scholar, Ovid, Scopus, and Science Direct. A total of 40 articles were utilized in this review. Collected data indicated that prenatal and post-natal supplementation with lactobacilli alone or lactobacilli …
The embryo-placental CD15-positive "vasculogenic zones" as a source of propranolol-sensitive pediatric vascular tumors.
2015
Abstract Objective Propranolol-induced involution is a unique biological feature of some pediatric vascular tumors, for instance infantile hemangioma (IH), cerebral cavernoma or chorioangioma. Currently, the cellular origin of these distinct tumors is unclear. In this study, we tested the hypothesis that propranolol-responsive vascular tumors are derived from common vessel-forming CD15 + progenitor cells which occur in early gestation. The aim of this study was to identify the tumor-relevant CD15 + progenitors at the early stages of embryo-placental development. Materials and methods Human embryo-placental units of 4–8 weeks gestation and pediatric vascular tumors were tested for expression…
Circulating progesterone levels and ongoing pregnancy rates in controlled ovarian stimulation cycles for in vitro fertilization: analysis of over 400…
2010
background: The influence of elevated serum progesterone levels during in vitro fertilization/intracytoplasmic sperm injection (IVF/ ICSI) cycles on pregnancy rates is a matter of continued debate among fertility clinicians. Efforts to resolve this question have been impeded by the various assays used to measure progesterone and the different, arbitrary threshold values for defining ‘high’ progesterone levels. methods: A non-interventional, retrospective, observational, single-centre cohort study evaluated the relationship between serum progesterone levels on the day of human chorionic gonadotrophin (hCG) administration and the ongoing pregnancy rate in 4032 patients undergoing IVF/ICSI cyc…
The heparin-glutathione test: an alternative to the hypo-osmotic swelling test to select viable sperm for intracytoplasmic sperm injection
1998
Abstract Objective: To evaluate the heparin-glutathione test (HEGLUT) for the selection of viable sperm for intracytoplasmic sperm injection (ICSI). Design: A prospective study. Setting: Department of Pediatrics, Obstetrics and Gynecology, University of Valencia and Instituto Valenciano de Infertilidad. Patient(s): Semen samples from healthy donors and patients with infertility. Intervention(s): Sperm samples were kept in culture for different periods in Ham's F-10 medium supplemented or not supplemented with heparin, reduced glutathione (GSH), or a heparin-GSH mixture. Control and heparin-GSH–treated spermatozoa were injected into hamster oocytes. The HEGLUT and ICSI were performed. Main O…
