Relationship between some maternal haemato-clinical parameters and low neonatal weight. Preliminary study
No full textIn a selected group of pregnant women we studied the influence of specific haematoclinical maternal factors (age, pre-pregnancy weight, pregnancy weight gain, blood pressure, haematocrit (HTC), haemoglobinaemia (Hb), platelets (PTL), uricaemia) on neonatal weight. The results show an association among pre-pregnancy low maternal weight, hypertension and low neonatal weight. The uricaemia behaviour and the role of PTL, Hb, HCT are uncertain

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Detailed ultrasound as a screening method for craniospinal abnormalities.
No full textHigh resolution diagnostic ultrasound was assessed as a screening method for craniospinal anomalies during the second trimester of pregnancy in a population at low risk for neural tube defects (83,403 mothers). The effectiveness of the test was about 60% and the failure rate mainly due to late attendance. In a subgroup (9325) where the screening purposes were satisfactorily fulfilled, the detection rate (87%) was substantially greater. The significance of the results and the cost/benefit ratio, especially compared with serum alpha-feto protein screening services, are then discussed
