Long-term mortality analysis in Parkinson's disease treated with deep brain sti...
Rocha, S; Monteiro, A; Linhares, P; Chamadoira, C; Bastos, MA; Reis, C; Sousa, C; Lima, J; Rosas, MJBackground. Few data have been published regarding long-term mortality in patients with Parkinson's disease treated with DBS. Methods. This study analyzed long-term mortality rates, causes, and correlates in PD patients treated with DBS. Results. 184 consecutive patients were included; mean follow-up was 50 months. Fifteen deaths occurred (total 8.15%, annual mortality rate 1.94%). Mean age at disease onset and...
Immunoglobulin genes implicated in glioma risk
Pandey, JP; Kaur, N; Costa, N; Amorim, J; Nabico, R; Linhares, P; Vaz, R; Viana-Pereira, M; Reis, RMBoth genetic and environmental factors are thought to be causal in gliomagenesis. Several genes have been implicated in glioma development, but the putative role of a major immunity-related gene complex member, immunoglobulin heavy chain γ (IGHG) has not been evaluated. Prior observations that IGHG-encoded γ marker (GM) allotypes exhibit differential sensitivity to an immunoevasion strategy of cytomegalovirus...
Impact of EGFR genetic variants on glioma risk and patient outcome
Costa, BM; Viana-Pereira, M; Fernandes, R; Costa, S; Linhares, P; Vaz, R; Pinheiro, C; Lima, J; Soares, P; Silva, A; Pardal, F; Amorim, J; Nabiço, RBACKGROUND: The epidermal growth factor receptor (EGFR) regulates important cellular processes and is frequently implicated in human tumors. Three EGFR polymorphisms have been described as having a transcriptional regulatory function: two single-nucleotide polymorphisms in the essential promoter region, -216G/T and -191C/A, and a polymorphic (CA)(n) microsatellite sequence in intron 1. We aimed to elucidate the...

Prognostic value of MGMT promoter methylation in glioblastoma patients treated ...
Costa, BM; Caeiro, C; Guimarães, I; Martinho, O; Jaraquemada, T; Augusto, I; Castro, l; Osório, L; Linhares, P; Honavar, M; Resende, M; Nabiço, RGlioblastoma (GBM) is the most common and aggressive primary brain tumor. The identification of novel molecular prognostic markers of GBM has recently been an area of great interest in neuro-oncology. The methylation status of the MGMT gene promoter is currently a promising molecular prognostic marker, but some controversial data have precluded its clinical use. We analyzed MGMT methylation by methylation-speci...
