Psychiatric admission during pregnancy in women with schizophrenia who attended a specialist antenatal clinic.

Objectives: The mental health and wellbeing of pregnant women with schizophrenia is an area of research interest. We aim to explore this relationship particularly in regards to psychiatric admission rates, timing and their associated contributing factors. Methods: A total of 98 pregnancies to women with schizophrenia, who attended a specialist antenatal clinic and delivered from July 2007 to February 2016, were retrospectively examined. The cohort was divided into two groups based on psychiatric admission. Descriptive data were analyzed using SPSS software. Results: Overall, 40.8% required psychiatric admission during pregnancy. A higher proportion of subjects had their initial psychiatric admission in the first trimester compared to the third trimester (p = .002). Of note, 10.2% were admitted within one month either side of conception. Women with admission also presented later for their first antenatal appointment (p = .04, 95% CI -2.1 to -1.9). Psychiatric admission was associated with substance (p = .014) and alcohol use (p = .001), child protective services involvement (p = .022) and infant being placed in out-of-home care (p = .01), but not with poorer obstetric or neonatal outcomes. Conclusion: High rates of psychiatric admission are evident throughout pregnancy for women with schizophrenia, with a high proportion of first presentations for admission occurring in the first trimester. Psychiatric admission is associated with poorer antenatal care attendance and adverse psychosocial outcomes, highlighting the need for enhanced multidisciplinary pregnancy care for this at risk group. Inpatient psychiatric services should consider pregnancy testing and contraception review for all women of childbearing age, admitted with schizophrenia.

Preparation of chitosan/magnetite composite beads and their application for removal of Pb(II) and Ni(II) from aqueous solution.

A simple and effective process has been proposed to prepare chitosan/magnetite nanocomposite beads with saturation magnetization value as high as uncoated Fe3O4 nanoparticles (ca. 54emu/g). The reason was that the coating chitosan layer was so thin that it did not affect magnetic properties of these composite beads. Especially, chitosan on the surface of the magnetic Fe3O4 nanoparticles is available for coordinating with heavy metal ions, making those ions removed with the assistance of external magnets. Maximum adsorption capacities for Pb(II) and Ni(II), occurred at pH 6 and under room temperature were as high as 63.33 and 52.55mg/g respectively, according to Langmuir isotherm model. These results permitted to conclude that chitosan/magnetite nanocomposite beads could serve as a promising adsorbent not only for Pb(II) and Ni(II) (pH=4-6) but also for other heavy metal ions in wastewater treatment technology.
