glutamate receptor antagonists reduced the mAMPH-induced Fos expression in cerebral cortex regions near the site of epidural application and reduced Fos immunoreactivity in striatel regions innervated by the affected cortical regions. Also, epidural application of the same concentration selleck compound of either antagonist during a binge mAMPH regimen blunted the mAMPH-induced striatel DAT depletions with a topography similar to its effects on Fos expression. These findings demonstrate that mAMPH-induced dopaminergic injury depends upon cortical NMDA and AMPA receptor activation and suggest the involvement of the corticostriatal projections in mAMPH neurotoxicity.

“Background The increased mortality of homeless people compared with non-homeless people might be linked to psychiatric disorders. However, homeless people are, because of their insufficient accommodation,

difficult to sample and monitor, which has limited previous studies. We aimed to assess registered psychiatric disorders, mortality, and predictors of mortality in the homeless shelter population in Denmark.

Methods We did a nationwide, prospective, register-based cohort study of homeless people aged 16 years and older who were registered in the Danish Homeless Register between Jan 1, 1999, and Dec 31, 2009. We calculated the proportion of registered psychiatric disorders, overall and cause-specific standardised mortality ratio (SMR), and life expectancy. Hazard ratios (HRs) were used to assess predictors of death.

Findings 32 711

homeless people (23 040 men and 9671 women) were included in the study population. 14 381 men (62.4%) and 5632 women (58.2%) had registered psychiatric disorders, and 11 286 men (49.0%) and 3564 women (36.9%) had a substance abuse diagnosis. Selleckchem Ispinesib During the study period, 3839 men (16.7%) and 951 women (9.8%) died. The overall SMR for men was 5.6 (95% CI 5.4-5.8) and for women was 6.7 (6.2-7.1), and external causes accounted for 1161 (27.9%) of 4161 deaths for which information on the cause was available. Remaining life expectancy at age 15-24 years was 21.6 years (95% CI 21.2-22.1) and 17.4 years (16.4-18.5) lower for homeless men and women, respectively, than the general population. Registered substance abuse disorder was associated with the highest mortality risk compared with no psychiatric contact registered (adjusted HR 1.4, 95% CI 1.3-1.5 for men; 1.7, 1.4-2.1 for women).

Interpretation Health problems are extensive in the homeless shelter population and there is an urgent need for more sustained efforts to reduce the high morbidity and mortality, especially from external causes. Register data is an important resource to supplement existing knowledge on homeless people with more valid and detailed information.”
