Gray matter (GM) volume deficits have been described in patients with schizophrenia (Sz) and bipolar disorder (BD), but to date, few studies have directly compared GM volumes between these syndromes with methods allowing for whole-brain comparisons. We have used structural magnetic resonance imaging (MRI) and voxel-based morphometry (VBM) to compare GM volumes between 38 Sz and 19 BD chronic patients. We also included 24 healthy controls. The results revealed a widespread cortical (dorsolateral and medial prefrontal and precentral) and cerebellar deficit as well as GM deficits in putamen and thalamus in Sz when compared to BD patients. Besides, a subcortical GM deficit was shown by Sz and BD groups when compared to the healthy controls, although a putaminal reduction was only evident in the Sz patients. In this comparison, the BD patients showed a limited cortical and subcortical GM deficit. These results support a partly different pattern of GM deficits associated to chronic Sz and chronic BD, with some degree of overlapping. © 2010 Springer-Verlag. Source

Objectives The aim of this study was to determine whether drug-eluting stents (DES) are superior to bare-metal stents (BMS) in octogenarian patients with angina. Background Patients >80 years of age frequently have complex coronary disease warranting DES but have a higher risk of bleeding from prolonged dual antiplatelet therapy. Methods This multicenter randomized trial was conducted in 22 centers in the United Kingdom and Spain. Patients >80 years of age underwent stent placement for angina. The primary endpoint was a 1-year composite of death, myocardial infarction, cerebrovascular accident, target vessel revascularization, or major hemorrhage. Results In total, 800 patients (83.5 ± 3.2 years of age) were randomized to BMS (n = 401) or DES (n = 399) for treatment of stable angina (32%) or acute coronary syndrome (68%). Procedural success did not differ between groups (97.7% for BMS vs. 95.4% for DES; p = 0.07). Thirty-eight percent of patients had >2-vessel percutaneous coronary intervention, and 66% underwent complete revascularization. Patients who received BMS had shorter stent implants (24.0 ± 13.4 mm vs. 26.6 ± 14.3 mm; p = 0.01). Rates of dual antiplatelet therapy at 1 year were 32.2% for patients in the BMS group and 94.0% for patients in the DES group. The primary endpoint occurred in 18.7% of patients in the BMS group versus 14.3% of patients in the DES group (p = 0.09). There was no difference in death (7.2% vs. 8.5%; p = 0.50), major hemorrhage (1.7% vs. 2.3%; p = 0.61), or cerebrovascular accident (1.2% vs. 1.5%; p = 0.77). Myocardial infarction (8.7% vs. 4.3%; p = 0.01) and target vessel revascularization (7.0% vs. 2.0%; p = 0.001) occurred more often in patients in the BMS group. Conclusions BMS and DES offer good clinical outcomes in this age group. DES were associated with a lower incidence of myocardial infarction and target vessel revascularization without increased incidence of major hemorrhage.

Background Internal tandem duplications of the FLT3 gene (FLT3-ITDs) are frequent in patients with acute promyelocytic leukemia (APL), however its clinical impact remains controversial. Design and Methods We analyzed the prognostic significance of FLT3-ITD mutant level and size, as well as FLT3-D835 point mutations, PML-RARa expression and other predictive factors in 129 APL patients at diagnosis enrolled on the Spanish LPA96 (n=43) or LPA99 (n=86) PETHEMA trials. Results FLT3-ITDs and D835 mutations were detected in 21% and 9% of patients, respectively. Patients with increased ITD mutant/wild-type ratio or longer ITD size displayed shorter 5-year relapse-free survival (RFS) (P=0.048 and P<0.0001, respectively). However, patients with D835 mutations did not show differences in RFS or overall survival (OS). Moreover, patients with initial normalized copy number (NCN) of PML-RARa transcripts less than the 25th percentile had adverse clinical features and shorter 5-year RFS (P<0.0001) and OS (P=0.004) compared to patients with higher NCN. Patients with low NCN showed increased incidence of ITDs (P=0.001), with higher ratios (P<0.0001) and/or longer sizes (P=0.007). Multivariate analysis showed that long FLT3-ITD (P=0.001), low PML-RARa levels (P=0.004) and elevated WBC counts (>10¥109/L) (P=0.018) were independent predictors for shorter RFS. We identified a sub-group of patients with high WBC, long FLT3-ITD and low NCN of transcripts that showed an extremely bad prognosis (5-year RFS 23.4%, P<0.0001). Conclusions In conclusion, FLT3-ITD size and PML-RARa transcript levels at diagnosis could contribute to improve the risk stratification in APL. © 2010 Ferrata Storti Foundation. Source

Aims: The aim of this work is to investigate the accuracy of the urea breath test (UBT) performed immediately after emergency endoscopy in peptic ulcer bleeding (PUB). Methods: Urea breath test was carried out right after emergency endoscopy in patients with PUB. The accuracy of this early UBT was compared to a delayed one after hospital discharge that was considered the gold standard. Clinical and epidemiological factors were analyzed in order to study their influence on the accuracy of the early UBT. Results: Early UBT was collected without any complication and good acceptance from all the 74 patients included. In 53 of the patients (71.6%), a delayed UBT was obtained. Comparing concordance between the two tests we have calculated an accuracy of 83% for the early UBT. Sensibility and specificity were 86.36 and 66%, respectively, with a positive predictive value of 92.68% and negative predictive value of 50% (Kappa index = 0.468; p = 0.0005; CI: 95%). We found no influence of epidemiological factors, clinical presentation, drugs, times to gastroscopy, Forrest classification, endoscopic therapy, hemoglobin, and urea levels over the accuracy of early UBT. Conclusions: Urea breath test carried out right after emergency endoscopy in PUB is an effective, safe, and easy-to-perform procedure. The accuracy of the test is not modified by clinical or epidemiological factors, ulcer stage, or by the type of therapy applied. However, we have found a low negative predictive value for early UBT, so a delayed test is mandatory for all negative cases. © Springer Science+Business Media, LLC 2012. Source

In this study we analyzed Spanish Post-Heart-Transplant Tumour Registry data for adult heart transplantation (HT) patients since 1984. Median post-HT follow-up of 4357 patients was 6.7 years. Lung cancer (mainly squamous cell or adenocarcinoma) was diagnosed in 102 (14.0% of patients developing cancers) a mean 6.4 years post-HT. Incidence increased with age at HT from 149 per 100 000 person-years among under-45s to 542 among over-64s; was 4.6 times greater among men than women; and was four times greater among pre-HT smokers (2169 patients) than nonsmokers (2188). The incidence rates in age-at-diagnosis groups with more than one case were significantly greater than GLOBOCAN 2002 estimates for the general Spanish population, and comparison with published data on smoking and lung cancer in the general population suggests that this increase was not due to a greater prevalence of smokers or former smokers among HT patients. Curative surgery, performed in 21 of the 28 operable cases, increased Kaplan-Meier 2-year survival to 70% versus 16% among inoperable patients. © 2011 The American Society of Transplantation and the American Society of Transplant Surgeons.
