The evaluation of amniotic fluid volume (AFV) is an established part of the antenatal surveillance of pregnancies at risk for an adverse pregnancy outcome. The two most commonly used ultrasound techniques to estimate AFV are the amniotic fluid index (AFI) and the single deepest pocket (SDP). Four studies have defined normal AFVs, and although their normal volumes have similarities, there are also differences primarily due to the statistical methodology used in each study. Dye-determined AFV correlates with ultrasound estimates for normal fluid volumes but correlates poorly for oligohydramnios and polyhydramnios...

BACKGROUND: Amniotic fluid (AF) is one of the major determinants of fetal biophysical profile and can predict pregnancy outcome. Abnormal value of amniotic fluid index (AFI) may indicate fetal and maternal disorders. PURPOSE: To establish reference standards for AFI for this population after 28 weeks of pregnancy and evaluate the relationship between AFI, the estimated fetal weight (EFWT), and fetal gender. MATERIAL AND METHODS: A prospective cross-sectional estimation of AFI and FWT was done in 385 apparently healthy pregnant women in the gestational age range of 28-42 weeks...

INTRODUCTION: Twin-twin transfusion syndrome (TTTS) complicates 15% of monochorionic twin pregnancies, often being associated with recipient cardiac dysfunction. Untreated, it has a fetal mortality rate of at least 90%; although treatment by fetoscopic laser coagulation significantly improves prognosis. Measurement of recipient amniotic fluid metabolites, such as cardiac Troponin T and atrial natriuretic polypeptide, correlate with cardiac function in this fetus. The aim of this study is to describe the amniotic fluid metabolomic profile in TTTS, relate this to fetal recipient cardiac function and assess the metabolomic changes induced by fetoscopic laser coagulation...

OBJECTIVE: To analyse the change in cardiac axis with advancing gestational age and the factors that may affect it. METHODS: 45 healthy pregnant women in 20th weeks of gestation were enrolled to the study. The cardiac axis was noted for each participant. The same group was once more assessed at term and the change in cardiac axis was calculated with the difference of cardiac axis at term and the 20th gestational weeks. Change in cardiac axis with advancing gestational weeks and factors that may affect it such as amniotic fluid index (AFI), estimated fetal weight (EFW) at term, actual birth weight and presentation of the fetus at term were evaluated...

OBJECTIVE: We aimed to determine the value of autopsy in fetuses with antenatally diagnosed oligohydramnios. PATIENTS AND METHODS: We evaluated all fetal losses over a period of 6.5 years. Those with oligohydramnios on antenatal scan were critically analyzed. Oligohydramnios was defined as amniotic fluid index of less than five objectively or as an obvious lack of liquor at subjective assessment. A detailed postmortem examination was carried out in all the fetuses after obtaining an informed consent...

INTRODUCTION: Women with a history of early-onset preeclampsia, requiring delivery before 34 weeks of gestation, often receive intensive surveillance with far more visits than routine antenatal care, additional testing such as the serial measurement of various fetal arterial Doppler blood flow velocity profiles, repetitive assessment of the fetal biometry, the amount of amniotic fluid, the fetal biophysical profile, and repetitive blood testing. Yet, recurrence risk is generally low. OBJECTIVES: To develop and validate a prepregnant prediction model to identify women at very low risk of recurrence of early-onset preeclampsia...

PURPOSE: The skeletal muscle develops various degrees of atrophy and metabolic dysfunction following nerve injury. Neurotrophic factors are essential for muscle regeneration. Human amniotic fluid derived stem cells (AFS) have the potential to secrete various neurotrophic factors necessary for nerve regeneration. In the present study, we assess the outcome of neurological function by intramuscular injection of AFS in a muscle denervation and nerve anastomosis model. MATERIALS AND METHODS: Seventy two Sprague-Dawley rats weighing 200-250 gm were enrolled in this study...

This pilot study examined the effectiveness of an Aquatic Exercise Program (AEP) provided by an occupational therapist for pregnant women on hospitalized bed rest. Researchers conducted a retrospective analysis of medical records of hospitalized pregnant women comparing those who attended an AEP (n = 19) to a control group who received no AEP (n = 12). Statistical tests were used to assess evidence of differences in length of gestation as well as blood pressure and amniotic fluid index (AFI) at discharge. Women who received an AEP had increased AFI and length of gestation compared to the control group...
