- Objective: Does snoring during pregnancy influence development of pre-eclampsia?Method: Five hundred and three pregnant women were presented a questionnaire concerning snoring, daytime sleepiness and edema. Epworth Sleepiness score (ESS) and symptoms of restless legs syndrome were also included. The questionnaire was presented in the 1st, 2nd and 3rd trimester and blood pressure was recorded. Women snoring often-always at visit 2 and/or 3 were denoted habitual snorers, those snoring never-seldom non-snorers and there was also a category occasional snorers. Habitual snorers were offered a sleep respiratory recording (Embletta); 34 volunteered.Results: 36/503 women (7,2%) snored habitually already at the first visit. At the end of pregnancy the fraction had increased to 19,5%. At the first visit BMI of habitual snorers was 25,3 compared to 22,9 for non-snorers (s.), but there was no difference concerning increase during pregnancy. Habitual snorers reported more edema at visit 2 and 3, higher scores in morning and daytime tiredness and ESS score compared to non-snorers at all visits (s.). Their systolic blood pressure increased more (s.) already between 1st and 2nd visit. Weight and Apgar scores of the newborns showed no difference. Pre-eclampsia developed in 18 women, twice as common among habitual snorers than in those snoring never-occasionally (n.s.). Their snoring scores were higher at all visits; the greatest difference at visit 3 (P50,058). Their diastolic pressure increased more already at the 2nd visit (s.), they had more edema and higher increase in BMI (s.). ESS and tiredness scores did not differ. 9/34 sleep recordings showed supine AHI 45. Two women who later developed pre-eclampsia were recorded; both had supine AHI 45.Conclusions: Habitual snorers had higher BMI from start, more daytime tiredness, higher ESS scores and their diastolic blood pressure increased more already during early pregnancy. Preeclampsia was twice as common among snorers as non-snorers; not significant due to the low number of cases. The relation between pre-eclampsia and snoring therefore remains elusive.

- The PHENIX tracking system consists of Drift Chambers (DC), Pad Chambers (PC) and the Time Expansion Chamber (TEC). PC1/DC and PC2/TEC/PC3 form the inner and outer tracking units, respectively. These units link the track segments that transverse the RICH and extend to the EMCal. The DC measures charged particle trajectories in the r-phi direction to determine P-T of the particles and the invariant mass of particle pairs. The PCs perform 3D spatial point measurements for pattern recognition and longitudinal momentum reconstruction and provide spatial resolution of a few mm in both r-phi and z. The TEC tracks particles passing through the region between the RICH and the EMCal. The design and operational parameters of the detectors are presented and running experience during the first year of data taking with PHENIX is discussed. The observed spatial and momentum resolution is given which imposes a limitation on the identification and characterization of charged particles in various momentum ranges.

- The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions. A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon. Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities. PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution. The detector consists of a large number of subsystems that are discussed in other papers in this volume. The overall design parameters of the detector are presented. (C) 2002 Elsevier Science B.V.

- OBJECTIVE: To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization.DESIGN: Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing.STUDY SAMPLE: Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data.RESULTS: For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization.CONCLUSIONS: A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.
