PREgnancy and FERtility Registry

The PREgnancy and FERtility (PREFER) study is a comprehensive program aiming to optimize care and improve knowledge around the topics of fertility preservation and pregnancy issues in young breast cancer patients. The program was initiated at the National Institute for Cancer Research, IRCCS AOU San Martino - IST in Genova (Liguria Region, Italy) and then it has been spread to other Italian Institutions under the umbrella of the Gruppo Italiano Mammella (GIM) study group. It is composed of two distinctive studies, one assessing fertility (i.e. PREFER-FERTILITY) and the other pregnancy (PREFER-PREGNANCY) issues. Hence, two different study protocols were developed under the umbrella of the PREFER registry. PREFER-FERTILITY aims to obtain and centralize data about the preferences and choices of young cancer patients on the fertility preservation strategies available in Italy. Furthermore, it aims to assess the outcomes of patients undergoing one or more strategies for fertility preservation in terms of success of the techniques (i.e. recovery of ovarian function, number of cryopreserved oocytes, post-treatment pregnancies) and safety (i.e. long-term survival outcomes). PREFER-PREGNANCY has two main objectives: 1) to obtain and centralize data on the management of breast cancer diagnosed during pregnancy, the obstetrical and paediatric care of children born after prior in utero exposure to anticancer treatments, and the long-term survival outcomes of these patients; 2) to obtain and centralize data on the clinical outcomes of breast cancer survivors that achieve a pregnancy after prior diagnosis and treatment of breast cancer.

A Diagnostic Test Study of Characteristic Sound Waves in the Middle and Third Trimester of Pregnancy Women

Pregnancy is a very complex and coordinated physiological process.The physiological changes are closely related to the physiological function of Zang-fu organs, which leads to the change of slippery pulse. By touching different levels of depth and the part of the radial artery, it is found that the formation mechanism of pulse information, especially unsmooth pulse, is similar to the principle of sonar emission and reception: the heart is equivalent to the transmitting device of sonar wave. Each contraction of the heart produces a cluster of powerful sound waves, which are rapidly transmitted to the whole body along the arterial wall and the blood in it as a medium. More than 90% of the arterial blood flow of normal organs and tissues is a steady laminar flow, which does not produce turbulence, so there is abnormal vibration when a certain organ and tissue has pathological changes. The arterial blood flow is squeezed and deformed which causing turbulence and abnormal vibrations, which are fused with a larger cluster of sound waves transmitted by the heart and then transmitted to the whole body. The investigators can feel this kind of sound waves which combine abnormal vibration waves by touching different levels of arteries close to the body surface, including the radial artery. At the same time, Professor Lucheng Song's team has conducted in-depth research on the characteristic unsmooth pulse of stable coronary heart disease, liver cirrhosis, gastritis and other diseases.During pregnancy, due to the significant increase in blood flow and maternal changes , the shape of sound waves transmitted to the radial artery in the artery will be changed. Professor Lucheng Song found in clinical practice that the pregnant pulse will have different sensations of smoothness and penetration in different parts of the finger, by touching different levels of depth and the part of the radial artery. It was found that the pulse condition of normal pregnant women in the middle and third trimester of pregnancy was different from that of normal non-pregnant women in different level and part of radial artery.This study will verify the efficacy of pulse diagnosis of traditional Chinese medicine in the diagnosis of pregnancy and lay a foundation for the diagnosis of abnormal pregnancy.

Biomarkers in Obstetrical Complications

Objective: To study the natural history of normal pregnancy and the most frequent pregnancy complications responsible for the excessive rate of perinatal morbidity and mortality, in order to develop models to predict the occurrence of these complications of pregnancy at the earliest possible time. The study focuses on the prediction of preterm labor with intact membranes, preterm prelabor rupture of membranes (PROM), preeclampsia, small for gestational age, gestational diabetes, and fetal death. These complications account for a minimum of $30 billion annually in the US alone. Study population: A cohort of pregnant women seeking care at the prenatal clinic of the Perinatology Research Branch in Detroit, Michigan. Design: A prospective observational cohort study of the natural history of women with a normal pregnancy, a history of adverse outcome, or those with a complication in the index pregnancy; therefore, this study will include nulliparous and parous women. Data will be collected at the time of clinic visits and will include interviews, clinical measurements, and ultrasound studies. We will assemble a biorepository of maternal biological fluids (blood, urine, saliva, cervicovaginal fluid, gingival crevicular fluid, swabs to characterize microbiota, amniotic fluid when a clinically indicated amniocentesis is performed). Placentas will be collected at the time of delivery as well as umbilical blood, and swabs to characterize the neonatal microbiota. We will use a retrospective case control and case-cohort design to generate models for the prediction of the most common pregnancy complications. These models will be developed by classifying obstetrical complications according to clinical presentation and histologic placental lesions. Models will be developed and subsequently validated in an independent cohort. Outcome measures: The goal is to develop sensitive, specific, and parsimonious predictive models to identify the patients at risk for developing complications of pregnancy using a combination of clinical and biological markers (biochemical and biophysical).

Prevalence and Impact of COVID-19 Infection in Pregnant Women, Fetuses and Newborns

A novel human coronavirus, named SevereAcute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), emerged in China, in late 2019, and is now spreading quickly causing a pandemic. It is usually responsible for a mild infectious syndrome, but patients can also develop pneumonia, acute respiratory failure and other serious complications. To date, very little and controversial literature is available on the impact of SARS-CoV-2 infection on pregnancy, and the potential risk of vertical transmission. Therefore, the first part of the study, will evaluate the proportion of pregnant woman infected by SARS-CoV-2 during pregnancy over the next six months by performing SARS-CoV-2 serology during pregnancy and at delivery . This information will be correlated to pregnancy and neonatal outcome. The second part of the study 2 will collect sera from several mandatory screening that are kept for one year. Those will be used for assessing the time of the seroconversion and variations of susceptibility to infection with gestational age as well as the impact of social distancing measures. Concerning neonates born to mothers with documented SARS-CoV-2 infection during pregnancy, only few cases of congenital infections were recently reported because of pneumonia related to SARS-CoV-2 infection and/or positive IgM at birth. It remains unclear whether neonatal infection can follow transplacental transmission of SARS-CoV-2 during pregnancy and/or through early per- and postnatal exposure, including breast-feeding. In order to investigate these hypotheses, the third part of the study will perform, SARS-CoV-2 PCR tests in a variety of samples collected from infected-mother (symptomatic during the pregnancy and PCR confirmed) and child pairs, at delivery and in the postpartum period.

Air Pollution and Daily Mobility of Pregnant Women Identification of Critical Windows of Exposure

This study is conducted to assess the role of pregnant women's daily mobility living in the Eurometropole of Strasbourg in a context of the existence of environmental exposure disparities (PM10, PM2.5, NO2). Furthermore, this study will tend to identify the critical windows of exposure and of greater risk of the adverse pregnancy outcomes as low birth weight and prematurity. A second question addressed in this work is to assess the relationship between the pregnant women's socio-economic status and the air pollution exposure (PM10, PM2.5, NO2).taking into account the spatio-temporal variations of the exposure as well as the critical windows of exposure during pregnancy. The present work deals with the following question "how does the combination of environmental exposure, socio-economic status and women's daily mobility, could contribute to socio-spatial inequalities in the health of the newborn? The underlying hypothesis is that the accumulation, in given area, of environmental exposures (as PM10, PM2.5 and NO2), of unfavorable living conditions (socio-economic environment) and individual factors (specific spatio-temporal trajectory) would induce an increased risk for the health of the newborn, (more particularly in terms of birth weight and term of birth). This hypothesis is structured 4 sub-hypotheses: i) The misclassification of exposure is socially distributed among pregnant women living in the Eurometropole of Strasbourg. ii) Beyond maternal and fetal characteristics, pregnant women who reside in a more socio-economically deprived neighborhood and / or with higher levels of environmental exposure to PM10, PM2.5 and NO2 are more at risk of preterm newborn and low birth weight newborn. iii) The accumulation of environmental exposures of the pregnant women and their daily mobility over their territory during the pregnancy increase the health inequalities of the newborn. iv) The critical windows of fetal exposure to pollutants is related to the socioeconomic level of their neighborhood and to the daily mobility of the women in their territory during pregnancy. Women are included in the study at the time of their first or second trimester ultrasound. Here are the tools used in the study: Descriptive survey of their idividuals characteristics, descriptive survey of women's mobility to assess their exposure during each trimester of pregnancy.
