Methods: From 2003 to 2007, 264,374 vascular operations were evaluated using the Nationwide Inpatient Sample database. Patients were stratified according to Non-Teaching (non-Teaching Hospital [NTH], n = 137,406), Teaching (Teaching Hospital [TH], n = 126,968), and Teaching with Vascular Surgery Training Program (VSH, n = 28,730) hospital status. Multivariate analyses were used to examine the effect of academic quarter (AQ) on mortality.
Results: Unadjusted mortality was higher at TH compared with NTH (2.5% vs 2.0%; P < .001). Aortic and peripheral Poziotinib vascular operations were more common
at TH, while carotid endarterectomy (P < .001) was more frequent at NTH (P < .001). After risk adjustment, the odds of death were significantly (P < .001) increased for aortic and peripheral vascular operations but were similar at both TH (1.11 [0.98-1.25]; P = .10) and VSH (1.16 [0.98-1.37]; P = .08) compared with NTH. Importantly, AQ was not associated with increased risk of mortality at either TH (AQ1 odds ratios [OR] = 0.95 [080-1.13], AQ2
OR = 1.08 [0.91-1.28], AQ3 OR = 1.13 [0.96-1.34], AQ4 = Reference; P = .19) or VSH (AQ1 OR = 1.02 [0.81-1.29], AQ2 OR = 0.99 [0.79-1.25], AQ3 OR = 1.02 [0.81-1.28], AQ4 = Reference; P = .99).
Conclusions: Mortality is not significantly influenced by operative time of year following Protein Tyrosine Kinase inhibitor vascular operations at academic centers. TH perform more high-risk operations compared with NTH with similar risk adjusted mortality. (J Vase Surg 2011;54:546-53.)”
“Disturbed cortical gamma-aminobutyric acid (GABA) neurotransmission in schizophrenia is evident from lamina- and cell type- specific alterations in Selleckchem Poziotinib presynaptic markers. In the dorsolateral prefrontal cortex
(DLPFC), these alterations include lower transcript expression of glutamic acid decarboxylase (GAD67) and somatostatin (SST), a neuropeptide expressed in the Martinotti subpopulation of GABA neurons whose axons innervate the distal apical dendrites of pyramidal neurons. However, whether the alterations in SST-containing interneurons are associated with changes in post-synaptic receptors for SST has not been examined. Thus, we used in situ hybridization to quantify the mRNA expression levels of SST receptors subtype 1 (SSTR1) and subtype 2 (SSTR2) in DLPFC area 9 from 23 matched pairs of subjects with schizophrenia and normal comparison subjects. We also assessed the effects of potential confounding variables within the human subjects and in brain specimens from macaque monkeys with long term exposure to antipsychotic drugs. SSTR1 mRNA levels did not differ between subject groups. In contrast, mean cortical SSTR2 mRNA levels were significantly 19% lower in the subjects with schizophrenia. Laminar and cellular level analyses revealed that lower SSTR2 mRNA levels were localized to pyramidal cells in cortical layers 5-6.
