A survey of contact with offspring and assistance with child care among parents with psychotic disorders

To help improve services for parents with psychotic disorders, patients with such disorders in three treatment agencies in Queensland, Australia, were surveyed about whether they were parents, how much contact they had with their offspring, and who provided assistance with child care. Of the 342 individuals with psychotic disorders mho participated in the study, 124 were parents. Forty-eight parents in the study had children under age 16, and 20 of these parents (42 percent) had their children living with them. Most parents relied on relatives or friends for assistance with child care. Barriers to child care services identified by parents were inability to pay, lack of local services, and fear of losing custody of children.

Glutamate(NMDA) receptor NR1 subunit mRNA expression in Alzheimer's disease

We analyzed the expression profile of two NMDAR1 mRNA isoform subsets. NR1(0xx) and NR1(1xx), in discrete regions of human cerebral cortex. The subsets are characterized by the absence or presence of a 21-amino acid N-terminal cassette. Reverse transcription polymerase chain reaction for NR1 isoforms was performed on total RNA preparations from spared and susceptible regions from 10 pathologically confirmed Alzheimer's disease (AD) cases and 10 matched controls. Primers spanning the splice insert yielded two bands, 342 bp (NR1(0xx)) and 405 bp (NR1(1xx)), on agarose gel electrophoresis. The bands were visualized with ethidium and quantified by densitometry. NR1(1xx) transcript expression was calculated as a proportion of the NR1(1xx) + NR1(0xx) total. Values were significantly lower in AD cases than in controls in mid-cingulate cortex, p < 0.01, superior temporal cortex, p < 0.01 and hippocampus, p similar to 0.05. Cortical proportionate NR1(1xx) transcript expression was invariant over the range of ages acid areas of controls tested, at similar to 50%. This was also true for AD motor and occipital cortex. Proportionate NR1(1xx) expression in AD cingulate and temporal cortex was lower at younger ages and increased with age: this regression was significantly different from that in the homotropic areas of controls. Variations in NR1 N-terminal cassette expression may underlie the local vulnerability to excitotoxic damage of some areas in the AD brain. Alternatively, changes in NR1 mRNA expression may arise as a consequence of the AD disease process.
