Non-invasive monitoring of pH and oxygen using miniaturized electrochemical sensors in an animal model of acute hypoxia
Background: One of the most prevalent causes of fetal hypoxia leading to stillbirth is placental insufficiency. Hemodynamic changes evaluated with Doppler ultrasound have been used as a surrogate marker of fetal hypoxia. ...
Fetal ischemia monitoring with in vivo implanted electrochemical multiparametric microsensors
Under intrauterine growth restriction (IUGR), abnormal attainment of the nutrients and oxygen by the fetus restricts the normal evolution of the prenatal causing in many cases high morbidity being one of the top-ten causes ...
in vivo Monitoring with micro-implantable hypoxia sensor based on tissue acidosis
Hypoxia is a common medical problem, sometimes difficult to detect and caused by different situations. Control of hypoxia is of great medical importance and early detection is essential to prevent life threatening ...
Neural encoding of voice pitch and formant structure at birth as revealed by frequency-following responses
Detailed neural encoding of voice pitch and formant structure plays a crucial role in speech perception, and is of key importance for an appropriate acquisition of the phonetic repertoire in infants since birth. However, ...
Reliability and Concurrent and Construct Validity of a Food Frequency Questionnaire for Pregnant Women at High Risk to Develop Fetal Growth Restriction
Accuracy of dietary assessment instruments such as food frequency questionnaire (FFQ) is crucial in the evaluation of diet-disease relationships. Test-retest reliability and concurrent and construct validity of a FFQ were ...
Micro-needle implantable electrochemical oxygen sensor: ex-vivo and in-vivo studies
Oxygen is vital for energy metabolism in mammals and the variability of the concentration is considered a clinical alert for a wide range of metabolic malfunctions in medicine. In this article, we describe the development ...
Miniaturized Electrochemical Sensors to Monitor Fetal Hypoxia and Acidosis in a Pregnant Sheep Model
Perinatal asphyxia is a major cause of severe brain damage and death. For its prenatal identification, Doppler ultrasound has been used as a surrogate marker of fetal hypoxia. However, Doppler evaluation cannot be performed ...
La influencia del estrés o ansiedad de la gestante en el peso fetal o neonatal: revisión bibliográfica
Objetivo: examinar si la presencia de ansiedad o estrés materno durante el embarazo influye en el peso del feto o el neonato y cómo cambian las variables asociadas. Metodología: Se llevó a cabo una revisión bibliográfica ...
Evaluación de una intervención mediante sofrología para disminuir la ansiedad en las gestantes con un feto con retraso de crecimiento
Objetivo: comparar el grado de ansiedad de un grupo de mujeres con un feto con retraso de crecimiento intrauterino (RCIU) visitadas exclusivamente por especialistas en medicina maternofetal en relación a otras mujeres que, ...
EVERREST prospective study: a 6-year prospective study to define the clinical and biological characteristics of pregnancies affected by severe early onset fetal growth restriction
BACKGROUND: Fetal growth restriction (FGR) is a serious obstetric condition for which there is currently no treatment. The EVERREST Prospective Study has been designed to characterise the natural history of pregnancies ...
Multiplex Antibody Analysis of IgM, IgA and IgG to SARS-CoV-2 in Saliva and Serum From Infected Children and Their Close Contacts
COVID-19 affects children to a lesser extent than adults but they can still get infected and transmit SARS-CoV-2 to their contacts. Field deployable non-invasive sensitive diagnostic techniques are needed to evaluate the ...
Comparison of 2D versus M-mode echocardiography for assessing fetal myocardial wall thickness
OBJECTIVE: M-mode and 2D have been proposed for evaluating fetal myocardial thickness. However, studies comparing the performance of both modalities are lacking. We aimed to compare 2D versus M-mode reproducibility for ...
Intrauterine growth restriction and later cardiovascular function
Intrauterine growth restriction is one of the most common obstetric conditions, affecting 7-10% of fetuses. Affected fetuses are actually exposed in utero to an adverse environment during the highly critical time of ...
Effects of Mediterranean Diet or Mindfulness-Based Stress Reduction on Prevention of Small-for-Gestational Age Birth Weights in Newborns Born to At-Risk Pregnant Individuals: The IMPACT BCN Randomized Clinical Trial
Importance: Being born small for gestational age (SGA) is a leading cause of perinatal morbidity and mortality with no effective prevention or therapy. Maternal suboptimal nutrition and high stress levels have been associated ...
Neurodevelopmental effects of undernutrition and placental underperfusion in fetal growth restriction rabbit models
Introduction: Chronic reduction of oxygen and nutrient delivery to the fetus has been related to neurodevelopmental problems. Placental underperfusion induces a significant reduction in oxygen and nutrient delivery, whereas ...
Antibody conversion rates to SARS-CoV-2 in saliva from children attending summer schools in Barcelona, Spain.
Background: Surveillance tools to estimate viral transmission dynamics in young populations are essential to guide recommendations for school opening and management during viral epidemics. Ideally, sensitive techniques are ...
The Mediterranean Diet in Pregnancy: Implications for Maternal Brain Morphometry in a Secondary Analysis of the IMPACT BCN Randomized Clinical Trial
Introduction: A Mediterranean diet has positive effects on the brain in mid-older adults; however, there is scarce information on pregnant individuals. We aimed to evaluate the effect of a structured Mediterranean diet ...
Fetal neurosonography and infant neurobehavior in assisted reproductive technologies following fresh and frozen embryo transfer
Objective: We aimed to explore fetal cortical brain development by neurosonography in fetuses conceived by assisted reproductive technology (ART), including frozen and fresh embryo transfer (ET), compared with those conceived ...
Revisiting MOMS criteria for prenatal repair of spina bifida: upper gestational-age limit should be raised and assessment of prenatal motor function rather than anatomical level improves prediction of postnatal function
Objectives: To determine if the lower-extremity neurological motor function level in fetuses with open spina bifida deteriorates within the 4-week interval between a first prenatal motor assessment at around 22 weeks of ...
Impact of the COVID-19 Pandemic on Maternal Well-Being during Pregnancy
The outbreak of a pandemic has negative psychological effects. We aimed to determine the impact of the SARS-CoV-2 pandemic during pregnancy and identify the risk factors for maternal well-being. A multicenter, prospective, ...
