The pathology of term placentas from seropositive human immunodeficiency virus(HIV)-infected and seronegative women was investigated byroutine histologic, immunocytochemical, in situ hybridization techniques. Placentas were evaluated forevidence villitis, chorioamnionitis, funisitis. Membranes, trophoblast, anddecidua also examined byimmunohistochemistry using monoclonal HIV p24 antibody. Twenty by combined immunochemical techniques, a 35S-labeled RNA probe complementary to the 3′long...

OBJECTIVE: To examine the prevalence and severity of postcesarean residual niche, evaluated using saline infusion sonohysterography, in an expanded cohort women with one prior cesarean delivery to assess effect uterine closure technique on risk placenta accreta spectrum (PAS) disorders. METHODS: This secondary analysis includes 70 patients who underwent sonohysterography after delivery. Patients were grouped according hysterotomy technique: two-layer endometrium-free (technique A), two- or...

This paper proposes a novel approach for detecting fetal heart rate (FHR) using seismo-cardiogram (SCG) and gyro-cardiogram (GCG) recordings collected from abdominal inertial sensors. A proof-of-concept setup with commercially available sensor nodes is prepared. The FHR components are extracted the fused cepstrum of all feasibility proposed method evaluated experiments on ten pregnant women under supine, seated, standing positions. results compared simultaneously-collected cardiotocography...

To compare the prevalence and size of residual niche in nongravid uterus following Cesarean delivery (CD) with different hysterotomy closure techniques (HCTs).Saline infusion sonohysterogram (SIS) was performed women after one prior CD, documenting presence or absence a postoperative measuring its depth, width, length, myometrial thickness. Women were grouped by HCT: Technique A (endometrium-free) B (routine non-endometrium-free). The primary outcome clinically significant niche, defined as...

This study attempts to determine the major source of lactate in normal and depressed human fetus, order assess applicability fetal blood measurement for evaluation stress during labor. We obtained umbilical arterial venous samples at delivery 132 liveborn infants, together with simultaneous maternal radial samples. All were analyzed immediately pH, gases, lactate. In vigorous newborns (1-minute Apgar score greater than or equal 7), levels lowest elective cesarean section done before onset...

Background Abnormal placentation can result in massive hemorrhage, which is the leading cause of severe maternal morbidities and mortality its management. Over past 50 years, incidence placenta previa (PP), abnormal implantation placenta, cesarean scar pregnancy have continued to rise. This coincides with well-documented parallel rise rate deliveries, performance multiple repeat deliveries adoption newer uterine closure techniques. However, no studies examined role techniques women a history...

Abstract Objectives To use saline infusion sonohysterography (SIS) to evaluate the effect of uterine closure technique on niche formation after multiple cesarean deliveries (CDs). Methods Patients with at least one prior CD were evaluated for via SIS. Subgroups any number repeat (>1 prior), lower-order (<4 and higher-order (≥4 prior) analyzed, stratifying by hysterotomy last preceding imaging; techniques included Technique A (endometrium-free double-layer closure) B (single- or routine...

To assess the diversity of uterine closure techniques (UCTs) among providers in one institution and evaluate concurrent consideration adverse outcomes for patient counseling, provisional care, prevention.Forty-four obstetricians at NYU Langone Health were emailed a survey their technique, practice experience. Results stratified by years practice: ≤5, 5-20, 20-40 years.Thirty-nine (88.6%) completed survey. Among those, blunt opening was preferred 29 (74.4%), mid-lower segment location favored...

This study presents a novel multi-modal framework for fetal heart rate extraction, which incorporates wearable seismo-cardiography (SCG), gyro-cardiography (GCG), and electrocardiography (ECG) readings from ten pregnant women. Firstly, signal refinement method based on empirical mode decomposition (EMD) is proposed to extract the desired components associated with (FHR). Afterwards, two techniques are developed fuse information different modalities. The first method, named early fusion,...

Cervical cerclage is a surgical procedure involving the placement of stitch within and around perimeter cervix, with purpose reinforcing its integrity thus preventing preterm delivery1. It usually performed using either McDonald or Shirodkar approaches2. Cerclage generally safe procedure3, few complications reported in literature4. Here we present case patient whom virtual three-dimensional (3D) ultrasound cystoscopy was instrumental imaging which eroded into bladder, leading to...

Abstract Objectives To determine whether amniotic fluid derived stem cells maintain their cell characteristics (a) after processing by a licensed therapy center and (b) the undergo simulated clinical application. Methods Amniotic was collected laparotomy – small uterine incision made at proposed site for delivery sterile catheter inserted to collect into bag. After flow stopped withdrawn, cesarean completed delivered cryostorage. A setting where received from were thawed room temperature...
