    Notes: Objective To determine the longitudinal changes in the incidence of bacterial vaginosis in pregnancy.Design A prospective study of women during pregnancy.Setting A District General Hospital in North-West London.Subject Seven hundred and eighteen pregnant women attending antenatal clinics. At their first attendance and subsequently, Gram-stained vaginal smears were examined and Mycoplasma hominis and Gardnerella vaginalis were sought by culture.Results Initially, 87 (12%) women had bacterial vaginosis diagnosed on Gram-stained reading of the vaginal smears. Examination of further smears, obtained from 176 women at 36 weeks of gestation, showed that those whose vaginal flora was normal initially, and who went to term, rarely developed vaginosis (three of 127, 2.4%). Samples were obtained at 36 weeks gestation from 32 women who had bacterial vaginosis initially, and went to term. In almost 50% (15 of 32) of these a normal lactobacillus-dominated flora had regenerated. Thirty-five women (5%) had initial vaginal smears graded as intermediate. From this group, six of the 17 (35%) women from whom samples were obtained at 36 weeks gestation still had flora of an intermediate pattern; 10 (59%) now had normal flora and only one (6%) had developed bacterial vaginosis. Women with bacterial vaginosis were more likely to be culture-positive for M. hominis than those with normal flora (34/78 versus 10/563, odds ratio 42.73 (18.9 to 102.3) P 〈 0.001), or to be culture-positive for G. vaginalis than those with normal flora (35/78 versus 21/563, odds ratio 21.0 (10.75 to 41.2) P 〈 0.001).Conclusion Pregnant women do not commonly develop bacterial vaginosis after 16 weeks gestation, and if present, it remits spontaneously in approximately half of those who reach term. As bacterial vaginosis is associated with increased rates of second trimester miscarriage and preterm delivery, any treatment aimed at its eradication in pregnancy should be given no later than the beginning of the second trimester of pregnancy.

    Notes: Objective To assess whether cervical cerclage in women deemed to be at increased risk of cervical incompetence prolongs pregnancy and thereby improves fetal and neonatal outcome.Design Multicentre randomised controlled trial.Setting Hospitals in the United Kingdom, France, Hungary, Norway, Italy, Belgium, Zimbabwe, South Africa, Iceland, Ireland, the Netherlands and Canada.Subjects One thousand two hundred and ninety-two pregnant women whose obstetricians were uncertain whether to recommend cervical cerclage, most of whom had a history of early delivery or cervical surgery.Interventions Cervical cerclage was compared with a policy of withholding the operation unless it was considered to be clearly indicated.Main outcome measures Delivery before 33 completed weeks, preterm delivery (〈37 weeks), and vital status of the baby after completion of the pregnancy.Results The overall preterm delivery rate was 28%. There were fewer deliveries before 33 weeks in the cerclage group (83 (13%) compared with 110 (17%), P=0.03) and this difference reflected deliveries characterised by features of cervical incompetence (painless cervical dilatation and prelabour rupture of the membranes). There was a corresponding difference in very low birthweight deliveries (63 (10%) compared with 86 (13%), P=0.05). The difference in the overall rate of miscarriage, stillbirth or neonatal death (55 (9%) compared with 68 (11%)) was less marked and was not statistically significant. The use of cervical cerclage was associated with increased medical intervention and a doubling of the risk of puerperal pyrexia.Conclusions These results suggest that the operation had an important beneficial effect in 1 in 25 cases in the trial (95% confidence interval (CI) 1 in 12 to 1 in 300 sutures). Its use is associated with increased medical intervention and puerperal pyrexia. Nevertheless, this trial suggests that, on balance, cervical cerclage should be offered to women at high risk, such as those with a history of three or more pregnancies ending before 37 weeks gestation.

    Notes: Epitaxial rare-earth–transition-metal thin films have been grown by magnetron sputtering onto buffered single-crystal MgO substrates. Results are presented for SmFe12(001) and magnetically hard Sm2Co7 and Sm2Co17 (110) films using W (100) buffer layers. The methodology of utilizing epitaxial W buffer layers combined with cosputtering from elemental sources provides a general approach to tailor the orientation and phase of the films. © 1997 American Institute of Physics.

    Spin polarization of the conduction bands and secondary electrons of Gd(0001) : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: Angle- and spin-resolved photoemission was utilized to investigate the 5d bulk bands and the surface state of Gd(0001) in the temperature range of 130–350 K. The bulk bands at 1–2 eV below the Fermi energy EF show Stoner-like behavior, while the temperature dependence of the surface state near EF indicates spin-mixing behavior due to fluctuating local 5d moments. The secondary electron spectra of the Gd surfaces both before and after initial oxygen adsorption show a polarization dip at low kinetic energies due to the extra scattering channel for minority electrons via the unoccupied 4f level. The temperature dependencies of the surface and bulk magnetization are separated using the spin polarization of the surface state and the bulk exchange splitting. © 1996 American Institute of Physics.

    Magnetic and structural instabilities of ferromagnetic and antiferromagnetic Fe/Cu(100) : The 6th joint magnetism and magnetic materials (MMM)-intermag conference (1994)

    Notes: Fe wedges epitaxially grown on Cu(100) have been employed to investigate the interplay between magnetic and structural instabilities. 2–4 monolayer (ML) clean Fe films grown at room temperature are ferromagnetic with perpendicular easy axes. bcc Fe films(approximately-greater-than)11 ML thick are ferromagnetic with in-plane easy axes. Most importantly, 6–11 ML fcc Fe films are antiferromagnetic and have a ferromagnetic surface. Films grown below 200 K and annealed to room temperature do not exhibit the antiferromagnetic phase, but remain ferromagnetic and undergo a spin-reorientation transition from perpendicular to in plane at ∼6 ML. A new phase diagram for Fe/Cu(100) is proposed as a function of thickness and growth temperature. In addition, an impurity-stabilized layer-by-layer growth that persists to 30–40 ML Fe is also reported.

    Ritodrine in the management of fetal distress (1982)

    Notes: Summary. The potential value of a bolus injection of ritodrine in the management of fetal distress was examined in 24 patients. Following the injection of ritodrine, uterine activity measured over a period of 14·7±6·3 (SD) min was reduced to 22 (±12·4 SD)% of the pre-existing values. The cardiotocographic tracings showed a reversion to a normal or less ominous pattern in 14 of the 16 patients where this could be evaluated. The infants in the ritodrine group took less time to establish regular respirations. The perinatal neurobehaviour in the ritodrine and control groups did not differ. Two mothers who were given ritodrine and who received atropine premedication developed tachycardia and marked systolic hypertension. The administration of a bolus of ritodrine may have a place in the management of fetal distress when caesarean section is unavoidably delayed, but atropine premedication must be avoided as the combination can lead to potentially serious cardiovascular complications.
