The effect of clinician education on blood transfusion practice in obstetrics: completing the audit cycle.

Background: With blood products being a limited and expensive resource within the healthcare system, there is an ever-increasing emphasis on judicial and appropriate use.

Aims: To evaluate whether implementing contemporary society recommendations on restrictive transfusion policies would reduce inappropriate use of red blood cell transfusions, by evaluating the effect of a staff educational campaign.

Methods: An audit of peri-partum red cell concentrate (RCC) transfusion practice within a tertiary obstetric unit was undertaken, covering a 1-year period (2015), examining data related to transfusion prescribing practices.

Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in neonatal sepsis.

Background: Efficient and accurate diagnosis of neonatal sepsis is challenging. The potential impact for a reduction in morbidity and mortality as well as antibiotic usage has stimulated the ongoing search for biomarkers of early sepsis. The objective of this pilot study was to quantify the levels of sTREM-1 and correlate with blood cultures and inflammatory markers in neonates evaluated for sepsis.

Histological chorioamnionitis is predicted by early infant C-reactive protein in preterm infants and correlates with neonatal outcomes.

Aim: Histological chorioamnionitis (HCA) is associated with preterm birth and adverse neonatal outcomes. We evaluated the rise in C-reactive protein (CRP) in preterm infants as a predictor of HCA severity and outcomes.

Methods: Consecutive preterm infants, born January 2009 to January 2014 in the National Maternity Hospital, Dublin, under 32 weeks' gestation or <1.

Evaluation of the Effect of Low-Dose Aspirin on Biochemical and Biophysical Biomarkers for Placental Disease in Low-Risk Pregnancy: Secondary Analysis of a Multicenter RCT.

Objective: To assess the effect of aspirin use in low-risk pregnancy on: (1) pregnancy-associated plasma protein-A (PAPP-A) and placental-like growth factor (PLGF); (2) urinary albumin-to-creatinine ratio (ACR) and blood pressure; (3) fetal growth parameters; and (4) placental histopathology.

Study Design: This secondary analysis from the rial of low-dose aspirin with an arly creening est for preeclampsia and growth restriction randomized controlled trial was based on low-risk nulliparous women randomized at 11 weeks to (1) aspirin 75 mg; (2) no aspirin; and (3) aspirin based on the preeclampsia Fetal Medicine Foundation screening test. At baseline, women underwent assessment of blood pressure, PAPP-A, PLGF, and ACR, repeated 9 to 10 weeks postaspirin, in addition to fetal growth assessment.

rial of feasibility and acceptability of routine low-dose aspirin versus arly creening est indicated aspirin for pre-eclampsia prevention ( study): a multicentre randomised controlled trial.

Objective: Evaluate the feasibility and acceptability of routine aspirin in low-risk women, compared with screening-test indicated aspirin for the prevention of pre-eclampsia and fetal growth restriction.

Design: Multicentre open-label feasibility randomised controlled trial.

Setting: Two tertiary maternity hospitals in Dublin, Ireland.

An open-label randomized-controlled trial of low dose aspirin with an early screening test for pre-eclampsia and growth restriction (TEST): Trial protocol.

Objective: Pre-eclampsia remains a worldwide cause of maternal and perinatal morbidity and mortality. Low dose aspirin (LDA) can reduce the occurrence of pre-eclampsia in women with identifiable risk factors. Emerging screening tests can determine the maternal risk of developing placental disease, such as pre-eclampsia from the first trimester of pregnancy.

Red cell alloimmunisation following intrauterine transfusion and the feasibility of providing extended phenotype-matched red cell units.

Objectives: To analyse the incidence of additional alloantibody formation following intrauterine red cell transfusion and to evaluate the feasibility of providing extended phenotype-matched red cells in future intrauterine transfusion (IUT).

Background: IUT is performed in severe, life-threatening fetal anaemia, usually in alloimmunised pregnancies. Its complications include the formation of additional alloantibodies to other red cell antigens.

A correlation between severe haemolytic disease of the fetus and newborn and maternal ABO blood group.

Objective: To analyse anti-D quantification levels and frequency of intrauterine transfusion (IUT), per maternal ABO blood group.

Background: Maternally derived red cell allo-antibodies can target fetal red cell antigens in utero leading to haemolytic disease and fetal anaemia. When a clinically significant allo-antibody is formed the priority is ascertaining the risk to the fetus and maternal ABO blood groups are not considered relevant.

Probiotics in obese pregnancy do not reduce maternal fasting glucose: a double-blind, placebo-controlled, randomized trial (Probiotics in Pregnancy Study).

Background: Recent studies have reported beneficial effects of probiotics on maternal glycemia in healthy pregnant women. Obesity significantly increases risk of impaired glucose tolerance in pregnancy, but glycemic effects of probiotics in this specific obstetric group require additional investigation.

Objective: The aim of the Probiotics in Pregnancy Study was to investigate the effect of a probiotic capsule on maternal fasting glucose in obese pregnant women.

Impact of a low glycemic index diet in pregnancy on markers of maternal and fetal metabolism and inflammation.

This is a secondary analysis of 621 women in ROLO study, a randomized control trial of low glycemic index (GI) diet in pregnancy to prevent the recurrence of macrosomia, which aims to assess the effect of the diet on maternal and fetal insulin resistance, leptin, and markers of inflammation. In early pregnancy and at 28 weeks, serum was analyzed for insulin, leptin, tumor necrosis factor α (TNF-α), and interleukin 6 (IL-6). At delivery, cord blood concentrations of leptin, TNF-α, IL-6, and C-peptide were recorded.

Effects of menstrual cycle phase on metabolomic profiles in premenopausal women.

Background: Characterization of the normal degree of physiological variation in the metabolomic profiles of healthy humans is a necessary step in the development of metabolomics as both a clinical research and diagnostic tool. This study investigated the effects of the menstrual cycle on (1)H nuclear magnetic resonance (NMR) derived metabolomic profiles of urine and plasma from healthy women.

Methods: In this study, 34 healthy women were recruited and a first void urine and fasting blood sample were collected from each woman at four different time points during one menstrual cycle.

Hyperprolactinaemia: analysis of presentation, diagnosis and treatment in the endocrine service of a general hospital.

The charts of 184 patients with clinically significant hyperprolactinaemia who presented to a teaching hospital between 1978-1995 were reviewed, 158 (86%) females and 26 (14%) males. Hyperprolactinaemia was due to a microadenoma or was idiopathic in 36.4%, drug induced in 16%, associated with a macroadenoma in 12%, due to epilepsy in 7%, with other causes each contributing 5% or less.

Steroidogenesis in an estrogen-producing adrenal tumor in a young woman: comparison with steroid profiles associated with cortisol- and androgen-producing tumors.

There is only one previous report of an estrogen-secreting adrenal tumor occurring in a woman during reproductive years. Our patient presented with mild hirsutism associated with menstrual bleeding every 3-6 weeks. The occurrence of apparently intermenstrual bleeding prompted an evaluation of estrogen levels.

Evaluation of an aldosterone radioimmunoassay: the renin-angiotensin-aldosterone axis as a function of sex and age.

A highly specific radioimmunoassay for aldosterone in plasma has been developed utilising extraction from plasma into dichloromethane, an antiserum raised to aldosterone-3-carboxy-methyloxime-BSA and a radio-iodinated derivative of aldosterone. The plasma values obtained after only extraction correlated very well with the results following chromatography over celite. The within- and between-batch variations for plasma pools ranged between 5 and 15%.

Adrenal abnormalities in polycystic ovary syndrome.

This study was undertaken to examine the role of adrenal androgen excess in the pathogenesis of polycystic ovary syndrome (PCOS) and, if such was present, to assess its reversibility using dexamethasone given in physiological dosage at night. Mean plasma testosterone (T), T/sex-hormone binding globulin (T/SHBG) ratio, androstenedione, and 17-OH-progesterone levels were elevated in the 19 patients studied. Plasma estrone values were elevated, whereas estradiol levels were normal.

The relationship between sex steroids and sex-hormone-binding globulin in plasma in physiological and pathological conditions.

Physiological and many pathological changes in plasma sex-hormone-binding globulin (SHBG) levels have been attributed to the opposing effects of androgens which lower, and oestrogens which elevate, levels. We examined four clinical situations in which changes in SHBG levels may not be explained by sex steroid alterations. (1) Dexamethasone caused an increase in SHBG levels in hyperandrogenaemic hirsute women whether or not androgens were suppressed.

Altered androstenedione and estrone dynamics associated with abnormal hormonal profiles in amenorrheic subjects with weight loss or obesity.

The present study was designed for exploration of hormonal disturbances underlying common forms of amenorrhea. Polycystic ovary syndrome (PCO) patients and obese amenorrheic subjects had significantly elevated estrone (E1) levels, elevated luteinizing hormone/follicle-stimulating hormone ratios, and an exaggerated luteinizing hormone response to luteinizing hormone-releasing hormone. However, androstenedione (delta 4A), the precursor of E1, was elevated only in PCO.

Variable clinical and hormonal manifestations of hyperandrogenemia.

This study was undertaken to contrast the hormonal profiles in patients with various hyperandrogenemic states in an attempt to correlate clinical manifestations with specific hormonal abnormalities. Patients with idiopathic hirsutism, polycystic ovaries, and a syndrome recently described by us, amenorrhea with cryptic hyperandrogenemia, ie, without hirsutism, participated. Total testosterone, the testosterone: sex-hormone-binding globulin (SHBG) ratio, and androstenedione levels were elevated in each group of patients.
