PURPOSE: To study the effects of gestational transient thyrotoxicosis (GTT) on pregnancy outcomes. METHODS: This case-control study retrospectively analyzed 7976 women with singleton pregnancies whose thyroid function was measured before 16 weeks of gestation and who delivered at ≥22 weeks of pregnancy. GTT was defined as hyperthyroidism (free thyroxine [FT4] level: ≥95th percentile) in the early pregnancy, which normalized in mid-pregnancy without thyroid-stimulating hormone receptor antibodies...

OBJECTIVE: To determine which parameter of the umbilical arterial cord gas analysis, pH, base deficit (BD) or lactate has a bigger predictive ability for neonatal morbidity at term. METHOD: We conducted a four year retrospective cohort study including all non-anomalous, singleton, vertex, term births with neonatal acidemia (umbilical arterial cord gas pH ≤ 7.1). The primary outcomes were a composite neurological morbidity and a composite systemic morbidity. The predictive ability of lactate, BD and pH were compared using ROC curves...

OBJECTIVE: To determine the diagnostic accuracy of fetal scalp lactate sampling (FSLS) and to establish an optimal cut-off value for intrapartum acidosis compared with fetal scalp pH. METHODS: A 20-month retrospective cohort study was conducted of all neonates delivered in our institution for whom fetal scalp blood sampling (FSBS) was performed, matching their intrapartum gasometry to their cord gasometry at delivery (n=243). The time taken from the performance of scalp blood sampling to arterial umbilical cord gas acquisition was 45 min at most...

Manufacture of red blood cells (RBCs) from progenitors has been proposed as a method to reduce reliance on donors. Such a process would need to be extremely efficient for economic viability given a relatively low value product and high 2E12 cell dose. Therefore, the aim of these studies was to define the productivity of an industry standard stirred-tank bioreactor and determine engineering limitations of commercial RBC production. Cord blood derived CD34+ cells were cultured under erythroid differentiation conditions in a stirred micro-bioreactor (ambr™)...

BACKGROUND: Previous evidence showed that use of phenylephrine was associated with higher umbilical artery pH (UA pH) than ephedrine after elective cesarean delivery (CD). However, the best choice of vasopressor and its effect on funic gases in cases of acute fetal compromise require additional studies. METHODS: Ninety parturients showing acute fetal compromise during intrapartum period and taken up for CD (category II) under spinal anesthesia were randomized to receive prophylactic infusion of ephedrine 2...

OBJECTIVE: Intradetrusor injection of onabotulinum toxin A (IDIBA) is the third-line therapy for patients with neurogenic detrusor overactivity (NDO). There is few evidence of long-term efficacy but no study assessed reasons for failure or abandonment of IDIBA and CISC (clean intermittent self-catheterization) combined strategy. We aimed to assess its long-term outcome in NDO management, and analyze failure and discontinuation. MATERIALS/PATIENTS AND METHODS: We retrospectively reviewed medical records of patients admitted in our neurourology department between 2001 and 2013...

To clarify the outcome of allogeneic hematopoietic cell transplantation (HCT) for leukemic transformation (LT) preceded by Philadelphia chromosome-negative (Ph-neg) myeloproliferative neoplasms (MPNs), we conducted a retrospective study using the national registry database of the Japan Society for Hematopoietic Cell Transplantation. From 2000 to 2013, 39 patients underwent their first allogeneic HCT with related bone marrow or peripheral blood stem cells (n = 8), unrelated bone marrow (n = 15), and unrelated umbilical cord blood (n = 16)...

OBJECTIVE: Vitamin D deficiency causes not only skeletal problems but also muscle weakness, including heart muscle. If the fetal heart is also affected, it might be more susceptible to fetal distress and birth asphyxia. In this pilot study, we hypothesised that low maternal vitamin D levels are over-represented in pregnancies with fetal distress/birth asphyxia. DESIGN AND SETTING: A population-based nested case-control study. PATIENTS: Banked sera of 2496 women from the 12th week of pregnancy...

With advancing gestation, partial pressure of oxygen (pO2) and pH fall significantly. Hypoxia is a main factor inducing free radical generation and thereby oxidative stress (OS). Placental and fetal tissue response when oxygen becomes restricted is complex and partially known. We tested the hypothesis that changes in umbilical artery and vein blood gas concentrations modulate OS occurrence in the newborn. Seventy umbilical artery and vein plasma samples were collected from healthy term newborns immediately after delivery...

BACKGROUND: The main documented indication of intrapartum caesarean section is foetal distress (MacKenzie and Cooke in BMJ 323(7318):930, 2001). Foetal distress indicates foetal hypoxia and acidosis during intrauterine life. PURPOSE: To correlate the diagnosis of foetal distress and perinatal outcome. METHODS: This was a prospective observational study of women who underwent caesarean section for foetal distress as detected by cardiotocography and not responding to intrauterine resuscitation...

Liver regeneration is delayed in mice with a defective TLR4 (C3H/HeJ) but is normal in TLR4 knockouts (TLR4(-/-) ). Here, we investigated the possible involvement of structural and hemodynamic changes in vivo in the underlying mechanism. In LPS-sensitive (C3H/HeN, C57BL/6) and LPS-insensitive (C3H/HeJ, TLR4(-/-) ) mice, a 70% partial hepatectomy (PH) was performed under inhalational anesthesia. At days 3 and 7 after PH, the hepatic microcirculation was interrogated using intravital microscopy. Delayed liver regeneration was confirmed in C3H/HeJ, but not in C3H/HeN, C57BL/6 (WT) or TLR4(-/-) mice by liver weight-to-body-weight ratio, percentage of PCNA-positive cells and mitotic index data...
