We investigated the therapeutic effects of aripiprazole (0.01-1.0mg/kg) and haloperidol (0.3 and 1.0mg/kg) on cognitive impairment in mice treated with PCP repeatedly.

Single (1.0mg/kg) and repeated (0.03 and 0.1mg/kg, for 7days) treatment with aripiprazole ameliorated PCP-induced impairment of recognition memory, although single treatment significantly decreased the total exploration time during the training session. In contrast, both single and repeated treatment with haloperidol (0.3 and 1.0mg/kg) failed to attenuate PCP-induced cognitive impairment. The ameliorating effect of aripiprazole on recognition memory in PCP-treated mice was blocked by co-treatment

with a dopamine D(1) receptor antagonist, SCH23390, and a serotonin 5-HT(1A) receptor antagonist, WAY100635; however, co-treatment with a D(2) receptor antagonist raclopride had no effect on the ameliorating effect of aripiprazole.

These results suggest that find more the ameliorative effect

of aripiprazole on PCP-induced memory impairment is associated with dopamine D(1) and serotonin 5-HT(1A) receptors.”
“Even though a large segment of the population lives in rural areas, relatively little attention has been paid in the literature to date to hospital use at the end of life among rural residents. The objective of this study was to examine factors associated with in- or out-of-region hospitalizations at the end of life among older rural residents.

The study included all community-dwelling adults aged 65 or BTSA1 older living in rural regions PAK6 of a mid-Western Canadian province who had died in fiscal years 2003-04 to 2005-06, as determined from Vital Statistics data (N =

5,550). Complete hospital discharge abstract data were used to identify in- or out-of-region hospitalizations in the last 6 months before death and on the day of death. The type of out-of-region hospitals older adults were admitted to was also examined (urban tertiary hospital, urban community hospital, and rural hospital).

Twenty percent of hospitalizations and 21% of hospital deaths occurred in a hospital that was out of older adults’ region of residence. Compared with decedents aged 65-74, those aged 75-84 and even more so those aged 85+ had reduced odds of being hospitalized out of region or dying in an out-of-region hospital. Those 85+ years old also had reduced odds of being hospitalized in a (out-of-region) tertiary hospital. Higher hospital bed rates and physician rates were associated with reduced odds of out-of-region hospitalization and hospital death.

Efforts should focus on recruiting physicians to those rural areas with low physician rates, as well as finding mechanisms to retain physicians in those rural regions.”
“Amyloid is a distinct beta-sheet-rich fold that many proteins can acquire. Frequently associated with neurodegenerative diseases in humans, including Alzheimer’s, Parkinson’s and Huntington’s diseases, amyloids are traditionally considered the product of protein misfolding.
