Abstract
![]()
The use of Ca(OH)2 as a CO2 sorbent instead
of CaO in calcium looping systems has the advantage of a much faster
reaction rate of carbonation and a larger conversion degree to CaCO3. This work investigates the carbonation kinetics of fine
Ca(OH)2 particles (<10 μm) in a range of reaction
conditions (i.e., 350–650 °C and CO2 concentrations
up to 25%v) that could be of interest for applications
where a short contact time is expected between the solids and the
gases (i.e., entrained bed carbonator reactors). For this purpose,
experiments in a drop tube reactor with short reaction times (i.e.,
below 6 s) have been carried out. High carbonation conversions up
to 0.7 have been measured under these conditions, supporting the viability
of using entrained carbonator reactors. The experimental results have
been fitted to a shirking core model, and the corresponding kinetic
parameters for the carbonation reaction have been determined.

Abstract
BACKGROUND Evidence suggests that the AKT1 gene may modulate the degree to which cannabis use induces cognitive alterations in patients with a psychotic disorder. AIM To examine the interplay between AKT1 and cannabis use in terms of the cognitive performance of the general population. METHODS Our sample consisted of 389 Spanish university students. Sustained attention was measured via the Continuous Performance Test-Identical Pairs, immediate and delayed verbal memory with the Logical Memory subtest of the Wechsler Memory Scale, and working memory with the Wisconsin Card Sorting Test. Lifetime cannabis use frequency was assessed and individuals were classified as cannabis users or non-users. Two single nucleotide polymorphisms of the AKT1 gene were genotyped and, according to previous studies, each subject was defined as a carrier of two, one or no copies of the haplotype (rs2494732(C)-rs1130233(A)). Multiple linear regressions were conducted to test the effect of the genetic variability and cannabis use (and their interaction) on cognitive performance. RESULTS An effect of the AKT1 haplotype was found on attention scores: individuals with two copies of the haplotype performed better (β=0.18, p<0.001 (adjusted for false discovery rate)), while neither cannabis nor the AKT1-cannabis interaction was associated with attention. No effect of AKT1, cannabis or the AKT1-cannabis interaction was found on verbal memory or working memory. CONCLUSIONS Our study provides additional evidence that AKT1 modulates cognitive performance. However, in our non-clinical sample, the previously reported interaction between cannabis use and the AKT1 gene was not replicated.

Abstract
BACKGROUND Around 8% of bipolar disorder (BD) patients die by suicide every year, accounting for the highest rate among the psychiatric population. Suicidal behavior (SB) is mediated by an intertwining system of extrinsic and intrinsic factors. Childhood trauma (CT) and gene variants of the stress-management hypothalamic-pituitary-adrenal (HPA) axis have been reported as risk factors for SB. The aim of this study was to elucidate the association of CT and HPA axis genetic variants with SB. METHODS 135 BD patients were recruited for clinical assessment of CT and SB by means of the Childhood Trauma Questionnaire (CTQ) and the Columbia Suicide Severity Rating Scale (C-SSRS), respectively. A total of 28 single nucleotide polymorphisms (SNPs) from 8 HPA axis genes (POMC, NR3C2, CRH-BP, NR3C1, FKBP5, CRHR2, CRHR1, and MC2R) were genotyped. RESULTS The analyses showed an association of total CTQ score (p = 0.003), emotional abuse (p = 0.001), sexual abuse (p = 0.005) and emotional neglect (p = 0.005) with SB. CRH-BP rs7728378-C carriers (p = 0.004; OR = 3.05), FKBP5 rs3777747-AA (p = 0.039; OR = 0.34) and FKBP5 rs2766533-GG genotypes (p = 0.001; OR = 2.93) were associated with SB although only rs2766533 survived multiple test correction. No gene-environment interaction was found. LIMITATIONS The relatively small sample size limits the statistical power to detect smaller environmental and genetic effects. Cross-sectional data collection in psychometric assessments can yield biased data. CONCLUSIONS The present study characterizes novel SB risk factors and replicates previous findings in BD patients. CT and variability in CRH-BP and FKBP5 genes should be further studied for a better understanding of SB and ultimately help in suicide prevention.

Abstract
The presence of abnormalities in emotional decision-making and reward processing among bipolar patients (BP) has been well rehearsed. These disturbances are not limited to acute phases and are common even during remission. In recent years, the existence of discrete cognitive profiles in this psychiatric population has been replicated. However, emotional decision making and reward processing domains have barely been studied. Therefore, our aim was to explore the existence of different profiles on the aforementioned cognitive dimensions in BP. The sample consisted of 126 euthymic BP. Main sociodemographic, clinical, functioning, and neurocognitive variables were gathered. A hierarchical-clustering technique was used to identify discrete neurocognitive profiles based on the performance in the Iowa Gambling Task. Afterward, the resulting clusters were compared using ANOVA or Chi-squared Test, as appropriate. Evidence for the existence of three different profiles was provided. Cluster 1 was mainly characterized by poor decision ability. Cluster 2 presented the lowest sensitivity to punishment. Finally, cluster 3 presented the best decision-making ability and the highest levels of punishment sensitivity. Comparison between the three clusters indicated that cluster 2 was the most functionally impaired group. The poorest outcomes in attention, executive function domains, and social cognition were also observed within the same group. In conclusion, similarly to that observed in "cold cognitive" domains, our results suggest the existence of three discrete cognitive profiles concerning emotional decision making and reward processing. Amongst all the indexes explored, low punishment sensitivity emerge as a potential correlate of poorer cognitive and functional outcomes in bipolar disorder.

Abstract
BACKGROUND Neuritin-1 is a neurotrophic factor involved in synaptic plasticity that has been associated with depressive disorders, schizophrenia and cognitive performance. The study of genotype-phenotype relationships in healthy individuals is a useful framework to investigate the etiology of brain dysfunctions. We therefore aimed to investigate in a non-clinical sample whether NRN1 gene contributes to the psychopathological profile, with a particular focus on the clinical dimensions previously related to the NRN1 gene (i.e. depressive and psychotic). Furthermore, we aimed to analyze: i) the role of NRN1 on executive functions, ii) whether the association between either NRN1-psychopathological profile or NRN1-cognitive performance is moderated by the BDNF gene. METHODS The sample comprised 410 non-clinical subjects who filled in the self-reported Brief Symptom Inventory (BSI) and were assessed for executive performance (Verbal Fluency, Wisconsin Card Sorting Test (WCST) and Letter-Number subscale (WAIS-III)). Genotyping included nine SNPs in NRN1 and one in BDNF. RESULTS i) GG homozygotes (rs1475157-NRN1) showed higher scores on BSI depressive dimension and on total scores compared to A carriers (corrected p-values: 0.0004 and 0.0003, respectively). ii) a linear trend was detected between GG genotype of rs1475157 and a worse cognitive performance in WCST total correct responses (uncorrected p-value: 0.029). iii) Interaction between rs1475157-NRN1 and Val66Met-BDNF was found to modulate depressive symptoms (p=0.001, significant after correction). LIMITATIONS Moderate sample size; replication in a larger sample is needed. CONCLUSIONS NRN1 is associated with depressive symptoms and executive function in a non-clinical sample. Our results also suggest that the role of NRN1 seems to be modulated by BDNF.

Abstract
BACKGROUND The interest in studying gene-gene interactions is increasing for psychiatric diseases such as schizophrenia-spectrum disorders (SSD), where multiple genes are involved. Dysbindin-1 (DTNBP1) and Neuritin-1 (NRN1) genes have been previously associated with SSD and both are involved in synaptic plasticity. We aimed to study whether these genes show an epistatic effect on the risk for SSD. METHODS The sample comprised 388 SSD patients and 397 healthy subjects. Interaction was tested between: (i) three DTNBP1 SNPs (rs2619537, rs2743864, rs1047631) related to changes in gene expression; and (ii) an haplotype in NRN1 previously associated with the risk for SSD (rs645649-rs582262: HAP-risk C-C). RESULTS An interaction between DTNBP1 rs2743864 and NRN1 HAP-risk was detected by using the model based multifactor dimensionality reduction (MB-MDR) approach (P=0.0049, after permutation procedure), meaning that the risk for SSD is significantly higher in those subjects carrying both the A allele of rs2743864 and the HAP-risk C-C. This interaction was confirmed by using a logistic regression model (P=0.033, OR (95%CI)=2.699 (1.08-6.71), R2=0.162). DISCUSSION Our results suggest that DTNBP1 and NRN1 genes show a joint effect on the risk for SSD. Although the precise mechanism underlying this effect is unclear, the fact that these genes have been involved in synaptic maturation, connectivity and glutamate signalling suggests that our findings could be of value as a link to the schizophrenia aetiology.

Abstract
OBJECTIVE Our aim was to analyse sociodemographic and clinical differences between non-suicidal (NS) bipolar patients (BP), BP reporting only suicidal ideation (SI) and BP suicide attempters according to Columbia-Suicide Severity Rating Scale (C-SRSS) criteria. Secondarily, we also investigated whether the C-SRSS Intensity Scale was associated with emergence of suicidal behaviour (SB). METHOD A total of 215 euthymic bipolar out-patients were recruited. Semistructured interviews including the C-SRSS were used to assess sociodemographic and clinical data. Patients were grouped according to C-SRSS criteria: patients who scored ≤1 on the Severity Scale were classified as NS. The remaining patients were grouped into two groups: 'patients with history of SI' and 'patients with history of SI and SB' according to whether they did or did not have a past actual suicide attempt respectively. RESULTS Patients from the three groups differed in illness onset, diagnosis, number of episodes and admissions, family history, comorbidities, rapid cycling and medication, as well as level of education, functioning, impulsivity and temperamental profile. CONCLUSION Our results suggest that increased impulsivity, higher rates of psychiatric admissions and a reported poor controllability of SI significantly increased the risk for suicidal acts among patients presenting SI.

Abstract
BACKGROUND The operationalisation of quality of life for people with more severe disabilities has been acknowledged in the published research for more than two decades. This study aims to contribute to our knowledge and understanding of the quality of life of adults with severe disabilities by developing a set of quality of life indicators appropriate to this population using a Delphi method and the eight-domain conceptual model proposed by Schalock & Verdugo (2002). METHOD The participating panel in the Delphi method included 12 experts who evaluated each proposed item according to four criteria: suitability, importance, observability and sensitivity. Descriptive analyses were used to select the best items in each of the four rounds of this Delphi study, as well as examining the coefficients of concordance that were calculated for the final pool of items. RESULTS The four rounds of the Delphi study resulted in a final pool of 118 items (91 that were considered valid in the first round plus 27 items proposed, reformulated or discussed in the following rounds). Importance and sensitivity were the criteria that received the highest and lowest ratings, respectively, but also the ones that had the highest and lowest mean coefficients of concordance. Experts showed the strongest agreement for items related to material well-being, while the weakest was found for items related to personal development. CONCLUSIONS This study further contributes to our understanding of how to operationalise and measure quality of life in adults with severe disabilities. The item pool generated may prove helpful in the development of instruments for the measurement of quality of life-related outcomes in this population.

Abstract
This paper documents the validation of a comprehensive scale designed to assess quality-of-life related personal outcomes for people with intellectual and developmental disabilities who receive support in social organizations. The INICO-FEAPS Scale was administered to 1627 people whose ages ranged between 16 and 72 years old. The instrument comprises 72 parallel items organized around eight quality-of-life domains in each of the two forms: a self-report and a report by others. Several internal consistence indexes showed a good reliability of the scale. CFA was used to compare the goodness-of-fit to the data of alternative models. The eight-correlated first-order factors showed the best fit to the data in comparison to the unidimensional solution and hierarchical models. The instrument serves as a helpful tool for organizations to operate as bridges to the community, develop person-centered planning and individualized support, and implement evidence-based practices for quality improvement.

Abstract
GOAL The present study aimed to examine the prevalence of child abuse across the continuum of psychosis. PATIENTS AND METHODS The sample consisted of 198 individuals divided in three groups: (1) 48 FEP patients, (2) 77 individuals scoring high in Community Assessment of Psychic Experiences (CAPE), classified as "High CAPE" group and (3) 73 individuals scoring low, classified as "Low CAPE" group. Childhood abuse was assessed using self-report instruments. Chi(2) tests and logistic regression models controlling by sex, age and cannabis were used to perform three comparisons: (i) FEP vs. Low CAPE; (ii) FEP vs. High CAPE and (iii) High CAPE vs. Low CAPE. RESULTS The frequency of individuals exposed to childhood abuse for FEP, High CAPE and Low CAPE groups were 52.1%, 41.6% and 11%, respectively. FEP and High CAPE group presented significantly higher rates of childhood abuse compared to Low CAPE group, however, no significant differences were found between FEP and High CAPE groups regarding the frequency of childhood abuse. CONCLUSION There is an increasing frequency of childhood abuse from low subclinical psychosis to FEP patients. However, childhood abuse is equally common in FEP and at risk individuals.

Abstract
PURPOSE To test whether firstly, different parental rearing components were associated with different dimensions of psychiatric symptoms in adulthood, secondly BDNF-Val66Met polymorphism moderated this association and thirdly, this association was due to genetic confounding. METHOD Perceived parental rearing according to Parental Bonding Instrument (PBI), psychiatric symptoms evaluated with the Brief Symptom Inventory (BSI) and the BDNF-Val66Met polymorphism were analyzed in a sample of 232 adult twins from the general population. RESULTS In the whole sample, paternal care was negatively associated with depression. Maternal overprotection was positively associated with paranoid ideation, obsession-compulsion and somatization. Gene-environment interaction effects were detected between the BDNF-Val66Met polymorphism and maternal care on phobic anxiety, paternal care on hostility, maternal overprotection on somatization and paternal overprotection also in somatization. In the subsample of MZ twins, intrapair differences in maternal care were associated with anxiety, paranoid ideation and somatization. CONCLUSIONS Met carriers were, in general, more sensitive to the effects of parental rearing compared to Val/Val carriers in relation to anxiety and somatization. Contra-intuitively, our findings suggest that high rates of maternal care might be of risk for Met carriers regarding anxiety. Results from analyses controlling for genetic confounding were in line with this finding.

Abstract
A recent publication reported an exciting polygenic effect of schizophrenia (SCZ) risk variants, identified by a large genome-wide association study (GWAS), on total brain and white matter volumes in schizophrenic patients and, even more prominently, in healthy subjects. The aim of the present work was to replicate and then potentially extend these findings. According to the original publication, polygenic risk scores-using single nucleotide polymorphism (SNP) information of SCZ GWAS-(polygenic SCZ risk scores; PSS) were calculated in 122 healthy subjects, enrolled in a structural magnetic resonance imaging (MRI) study. These scores were computed based on P-values and odds ratios available through the Psychiatric GWAS Consortium. In addition, polygenic white matter scores (PWM) were calculated, using the respective SNP subset in the original publication. None of the polygenic scores, either PSS or PWM, were found to be associated with total brain, white matter or gray matter volume in our replicate sample. Minor differences between the original and the present study that might have contributed to lack of reproducibility (but unlikely explain it fully), are number of subjects, ethnicity, age distribution, array technology, SNP imputation quality and MRI scanner type. In contrast to the original publication, our results do not reveal the slightest signal of association of the described sets of GWAS-identified SCZ risk variants with brain volumes in adults. Caution is indicated in interpreting studies building on polygenic risk scores without replication sample.

Abstract
OBJECTIVE To test whether the association between childhood abuse, cannabis use and psychotic experiences (PEs) was moderated by the COMT (catechol-O-methyltransferase) gene. METHOD Psychotic experiences (PEs), childhood abuse, cannabis use and COMT Val158Met genotypes were assessed in 533 individuals from the general population. Data were analysed hierarchically by means of multiple linear regression models. RESULTS Childhood abuse showed a significant main effect on both positive (β = 0.09; SE = 0.04; P = 0.047) and negative PEs (β = 0.11; SE = 0.05; P = 0.038). A significant three-way interaction effect was found among childhood abuse, cannabis use and the COMT gene on positive PEs (β = -0.30; SE = 0.11; P = 0.006). This result suggests that COMT genotypes and cannabis use only influenced PE scores among individuals exposed to childhood abuse. Furthermore, exposure to childhood abuse and cannabis use increased PE scores in Val carriers. However, in individuals exposed to childhood abuse but who did not use cannabis, PEs increased as a function of the Met allele copies of the COMT gene. CONCLUSION Cannabis use after exposure to childhood abuse may have opposite effects on the risk of PEs, depending on the COMT genotypes providing evidence for a qualitative interaction. Val carriers exposed to childhood abuse are vulnerable to the psychosis-inducing effects of cannabis.

Abstract
Bipolar patients (BP) are at high risk of suicide. Causal factors underlying suicidal behavior are still unclear. However, it has been shown that lithium has antisuicidal properties. Genes involved in its putative mechanism of action such as the phosphoinositol and the Wnt/β-catenine pathways could be considered candidates for suicidal behavior (SB). Our aim was to investigate the association of the IMPA1 and 2, INPP1, GSK3α and β genes with suicidal behavior in BP. 199 BP were recruited. Polymorphisms at the IMPA1 (rs915, rs1058401 and rs2268432) and IMPA2 (rs66938, rs1020294, rs1250171 and rs630110), INPP1 (rs3791809, rs4853694 and 909270), GSK3α (rs3745233) and GSK3β (rs334558, rs1732170 and rs11921360) genes were genotyped. All patients were grouped and compared according to the presence or not of history of SB (defined as the presence of at least one previous suicidal attempt). Single SNP analyses showed that suicide attempters had higher frequencies of AA genotype of the rs669838-IMPA2 and GG genotype of the rs4853694-INPP1gene compared to non-attempters. Results also revealed that T-allele carriers of the rs1732170-GSK3β gene and A-allele carriers of the rs11921360-GSK3β gene had a higher risk for attempting suicide. Haplotype analysis showed that attempters had lower frequencies of A:A haplotype (rs4853694:rs909270) at the INPP1 gene. Higher frequencies of the C:A haplotype and lower frequencies of the A:C haplotype at the GSK-3β gene (rs1732170:rs11921360) were also found to be associated to SB in BP. Therefore, our results suggest that genetic variability at IMPA2, INPP1 and GSK3β genes is associated with the emergence of SB in BP.

Abstract
OBJECTIVE The aims of this study were to test the individual association of the serotonin transporter gene (SLC6A4), the brain-derived neurotrophic factor gene (BDNF) and the GABA(A) α(6) receptor subunit gene (GABRA6) with anxiety-related traits and to explore putative gene-gene interactions in a Spanish healthy sample. METHOD A sample of 937 individuals from the general population completed the Temperament and Character Inventory questionnaire to explore Harm Avoidance (HA) dimension; a subsample of 553 individuals also filled in the Big Five Questionnaire to explore the Neuroticism dimension. The whole sample was genotyped for the 5-HTTLPR polymorphism (SLC6A4 gene), the Val66Met polymorphism (BDNF gene) and the T1521C polymorphism (GABRA6 gene). RESULTS Homozygous individuals for the T allele of the T1512C polymorphism presented slightly higher scores for HA than C allele carriers (F = 2.96, P = 0.019). In addition, there was a significant gene-gene interaction on HA between the 5-HTTLPR and Val66Met polymorphisms (F = 3.4, P = 0.009). CONCLUSION GABRA6 emerges as a candidate gene involved in the variability of HA. The effect of a significant gene-gene interaction between the SLC6A4 and BDNF genes on HA could explain part of the genetic basis underlying anxiety-related traits.

Abstract
BACKGROUND Impulsivity is substantially higher in bipolar patients (BP) and may be associated with a more severe course of illness, but no studies have so far examined the relationship between impulsivity and functional outcome in BP. Our goal was to investigate the functional impact of trait-impulsivity in BP. METHODS 138 euthymic BP were recruited. All patients were assessed using an interview based on the Structured Clinical Interview for DSM Disorders (SCID). The Functioning Assessment Short Test (FAST) and the Barratt Impulsiveness Scale (BIS-11) were used to assess functional outcome and impulsivity, respectively. Seven multiple linear regressions, with each individual FAST subscale scores and overall FAST score as dependant variables, were conducted in order to evaluate the predictive role of trait-impulsivity on functional outcome. RESULTS After a multiple linear regression model, with the FAST total score as dependent variable, we found that depressive symptoms (β=1.580; p<0.001), number of hospitalizations (β=0.837; p=0.019) and impulsivity (β=0.319; p=0.004) were independently associated with overall functional impairment (F=6.854, df=9, p<0.001, adjusted R2=0.311). LIMITATIONS The cross-sectional design of the study. CONCLUSIONS Our results indicate that impulsivity, as well as depressive symptoms and the number of hospitalizations, is associated with overall functional impairment in BP. The assessment and treatment of impulsivity may be useful in improving functional outcome in BP.

Abstract
IntroductionThe well-established relationship between childhood adversity and psychosis is likely to involve other factors such as genetic variants, which could help to understand why not everyone exposed to adverse events develops psychotic symptoms later in life (Van Winkel, et al. 2008; Simmons et al. 2009).AimsThe present study investigated the influence of childhood abuse and neglect on positive and negative psychosis-like experiences in adulthood and the potential moderating effect of the BDNF-Val66Met polymorphism.MethodPsychosis-like experiences and childhood adversity were assessed in 533 individuals from the general population.ResultsChildhood abuse showed a strong independent effect on the positive dimension of psychosis-like experiences (B = .16; SE = .05; p = .002). Furthermore, this association was moderated by the BDNF-Val66Met polymorphism (B = .17; SE = .09; p = .004).ConclusionsIndividuals exposed to childhood abuse are more likely to report positive psychosis-like experiences. Met carriers reported more positive psychosis-like experiences when exposed to childhood abuse than did individuals carrying the Val/Val genotype.Therefore, the observed gene-environment interaction effect may be partially responsible for individual variation in response to childhood abuse.

Abstract
IntroductionDifferent studies have confirmed the association between cannabis use and psychosis and, also, the relationship between age at first cannabis use and age at onset of psychosis (Henquet et al 2005, Barnes et al 2006). In a young psychiatric sample, we aimed to investigate the correlation between cannabis use and the age at onset of psychotic and non-psychotic symptoms and whether this relationship is modulated by the genetic variability at COMT, CNR1 and CHRNA7genes.MethodsThe sample comprised 157 Caucasian patients (mean age: 17.01 (3.6)) diagnosed following DSM-IV-TR criteria: 80 patients with schizophrenia-spectrum disorders, 77 patients with affective or conduct disorders. Cannabis use was assessed with UNICA-A and DIGS scales (Nurnberger 1994) and 49% individuals were classified as consumers. SNPs were genotyped using Taqman 5′-exonuclease assays.ResultsWe observed a positive relationship between age at first cannabis use and age at onset in, both, schizophrenia-spectrum (β = 1.44 p < 0.001) and other psychiatric disorders (β = 0.56 p < 0.002). An interaction was observed between COMT Val158Met polymorphism and cannabis use specifically within schizophrenia-spectrum disorders’ group (β = −2.72 p = 0.04), with Val/Val genotype carriers showing an earlier age of onset than Val/Met carriers, and these, lower than the Met/Met carriers. No modulation effect of CNR1 or CHRNA7 polymorphisms was observed.ConclusionsOur results seem to indicate the importance of maturation timing and brain development in which exposition to cannabis occurs. We provide new evidence about the COMT modulation effect on the association between cannabis use and age at onset of symptoms, specifically in individuals affected by schizophrenia-spectrum disorders.

Abstract
Four coals of different rank were gasified, using a steam/oxygen mixture as gasifying agent, at atmospheric and elevated pressure in a fixed bed reactor fitted with a solids feeding system in continuous mode. Independently of coal rank, an increase in gasification pressure led to a decrease in H(2) + CO production and carbon conversion. Gasification of the different rank coals revealed that the higher the carbon content and reactivity, the greater the hydrogen production. Co-gasification experiments of binary (coal-biomass) and ternary blends (coal-petcoke-biomass) were conducted at high pressure to study possible synergetic effects. Interactions between the blend components were found to modify the gas production. An improvement in hydrogen production and cold gas efficiency was achieved when the coal was gasified with biomass.

Abstract
BACKGROUND Adverse childhood experiences have been described as one of the major environmental risk factors for depressive disorder. Similarly, the deleterious impact of early traumatic experiences on depression seems to be moderated by individual genetic variability. Serotonin transporter (5-HTT) and brain-derived neurotrophic factor (BDNF) modulate the effect of childhood adversity on adult depression, although inconsistencies across studies have been found. Moreover, the gene x environment (GxE) interaction concerning the different types of childhood adversity remains poorly understood. The aim of this study was to analyse the putative interaction between the 5-HTT gene (5-HTTLPR polymorphism), the BDNF gene (Val66Met polymorphism) and childhood adversity in accounting for adult depressive symptoms. METHOD A sample of 534 healthy individuals filled in self-report questionnaires of depressive symptomatology [the Symptom Check List 90 Revised (SCL-90-R)] and different types of childhood adversities [the Childhood Trauma Questionnaire (CTQ)]. The 5-HTTLPR polymorphism (5-HTT gene) and the Val66Met polymorphism (BDNF gene) were genotyped in the whole sample. RESULTS Total childhood adversity (beta=0.27, p<0.001), childhood sexual abuse (CSA; beta=0.17, p<0.001), childhood emotional abuse (beta=0.27, p<0.001) and childhood emotional neglect (beta=0.22, p<0.001) had an impact on adult depressive symptoms. CSA had a greater impact on depressive symptoms in Met allele carriers of the BDNF gene than in the Val/Val group (F=5.87, p<0.0001), and in S carriers of the 5-HTTLPR polymorphism (5-HTT gene) (F=5.80, p<0.0001). CONCLUSIONS Childhood adversity per se predicted higher levels of adult depressive symptoms. In addition, BDNF Val66Met and 5-HTTLPR polymorphisms seemed to moderate the effect of CSA on adult depressive symptoms.

Abstract
Working memory has been described as a neurocognitive probe of prefrontal brain functioning. Genetic variability related with catechol-O-methyltransferase (COMT) gene (Val158Met polymorphism) has received increasing attention as a possible modulator of working memory tasks in both schizophrenic patients and healthy subjects, although inconsistencies across studies have been found. This may be related to the existence of different working memory components, processes and modalities, which may have different sensitivities to subtle changes in dopamine levels and, therefore, the effect of the underlying COMT Val158Met genetic variability. To test this out a large sample of 521 healthy individuals from the general population were tested on the WCST and three working memory tasks that cover the assessment of verbal and spatial working modalities as well as different components and processes (Letter and Number Sequencing, CPT-IP, Backwards Visual Span). All individuals were genotyped for the rs4680 (Val158Met) polymorphism at the COMT gene. Met carriers showed near-significant better performance in the LNS compared with Val/Val individuals (F = 3.9, df = 1, P = 0.046). Moreover, the analysis for linear trend found that Met allele carriers showed significantly better performance than Val/Val individuals (B = 0.58 P = 0.031), although evidence for a linear trend was not found. None of the WCST indices differed among genotypes. Consistent with the hypothesis that Val158Met polymorphism (COMT gene) might account for individual differences on dopamine-dependent prefrontally related neurocognitive functions, the Letter-Number Sequencing task, which requires not only maintenance but also active manipulation of information seemed to be more sensitive to the disadvantageous Val/Val genotype in a large non-clinical sample.

Abstract
The brain microdialysis technique has been used to examine the in vivo effects of the neurotoxin domoic acid (an ionotropic glutamate receptor agonist) on dopamine (DA) release in the striatum of conscious and freely moving rats. Local application of domoic acid (500 microM) through the microdialysis probe produced an increase in striatal DA content (597 +/- 96% with respect to basal levels). The release of DA induced by domoic acid was not attenuated in a Ca(+2)-free medium (469 +/- 59%) or after pretreatment with 10 mg/kg reserpine (533 +/- 79%). Intrastriatal infusion of 1 microM tetrodotoxin (TTX) partially reduced the domoic acid-evoked DA release (278 +/- 34%). Moreover, domoic acid perfusion had no effect on K+-evoked DA release. The results suggest that domoic acid increases the striatal DA release according to a reserpine-independent, calcium-independent and partially TTX-insensitive mechanism, suggesting that these effects probably involve a nonexocytotic process. On the other hand, the inhibitor of DA uptake nomifensine (10 microM) reduced the domoic acid-evoked DA release (356 +/- 59%), suggesting that a carrier-dependent mechanism could be involved in the effect of domoic acid on the striatal DA levels.

Abstract
The mortality rate of infants with congenital diaphragmatic hernia (CDH) remains high, despite clinical improvements. Many attempts have been made to find accurate and reliable predictors of outcome. Deadspace (Vd/Vt) and dynamic compliance (DC) measured by single breath CO2 analysis may be useful to evaluate pulmonary function and perfusion. In the present study we analyse both parameters in patients with CDH. Nine patients with CDH were included for Vd/Vt and DC study. Measurements of arterial blood gases (pH, PO2, pCO2) were obtained, oxygenation index and alveolo-arterial difference calculated at diagnosis, preoperatively and postoperatively. Vd/Vt and DC were measured at the same moments by analysis of the CO2 espirogram. Statistical analysis was performed using Fisher exact test, ANOVA and Mann Whitney and Chi-square. The Vd/Vt was significant lower for the group of patients who survived (0.39 +/- 0.07 vs 0.64 +/- 0.14, p = 0.038). DC was significantly higher in the survivors group (1.39 +/- 0.30 vs 0.5 +/- 0.07, p = 0.011). The analysis of the evolutive Vd/Vt and DC (initial and preoperative) showed significant differences within both groups. Respiratory deadspace can be easily quantified in neonates with congenital diaphragmatic hernia providing an important insight regarding the efficiency of the airway-alveolus and its relationship to pulmonary blood flow. Vd/Vt and DC measurement constitute a reliable method to predict outcome in patients with CDH.

Abstract
Several lines of evidence suggest that genetic factors constitute an important determinant of suicidal behavior. A significant association between the 5-HT(2A)-C allele and suicidality has recently been reported. The aim of this study was to investigate whether the proposed association between 5-HT(2A)-102T/C polymorphism and suicidality could be replicated in a larger and independent sample of Spanish patients with major depression. The 102T/C polymorphism of the 5-HT(2A) receptor gene was analyzed in 159 patients with major depression (DSM-IV criteria) and 164 unrelated and healthy controls using a case control design. All individuals were subjects of Spanish origin. Significant differences in allele (chi-square = 4.13, df = 1, P = 0.04) and genotype (chi-square = 6.19, df = 2, P = 0.04) distributions were found between non-suicide attempters and suicide attempters. Moreover, those patients carrying 5-HT(2A)-C allele had more than five times the risk for attempting suicide than noncarriers (OR = 5.50, 95% CI = 1.18-35.20, P = 0.01). Our results replicate the proposed association between 5HT(2A)-C allele and suicidality in major depression. Moreover, no overall associations are detected when patients with major depression and controls are compared for 102T/C frequencies, suggesting that the increased risk for suicidality conferred by 5-HT(2A)-C allele is primarily associated with suicidal behavior and not with the diagnosis of major depression itself.

Abstract
A number of studies have shown the importance of dermatoglyphics as markers of prenatal disturbance in developmental disorders of unknown origin. Genetic and non-genetic factors are involved in the aetiology of intellectual disability (ID), although the cause remains unknown in up to 50% of cases. The aim of the present study was to analyse dermatoglyphic traits and abnormal palmar flexion creases as markers of environmental prenatal stress in children with idiopathic ID (IID) using a case-control study design. Three dermatoglyphic variables, which have been reported as altered in other congenital disorders, were considered were studied in a sample of 62 children with IID (IQ < 70) and 75 healthy controls (IQ > 70): (1) fingerprint patterns; (2) total a-b ridge count (TABRC); and (3) abnormal palmar flexion creases (APFCs). More arches, the simplest fingerprint pattern, and more radial loops, an unusual pattern, were found in IID cases in comparison to controls (chi23 = 9.26; P = 0.02), with especially marked differences in boys (chi23 = 6.5; P = 0.0008). A significant increase of APFCs was also found in the affected children (chi24 = 28.52; P < 0.00; odds ration = 3.86, 95% confidence interval = 1.77-8.47). For TABRC, the differences between IID cases and controls failed to reach the conventional level of significance. These findings suggest that environmental factors acting early in development, or mechanisms involving an interaction of genotype and environment could be involved in the aetiology of some cases of ID.

Abstract
Two recently described adjacent DNA polymorphisms [(GT)12-18 and (CT)4-5] in the 5'-regulatory region of 5-HT2C receptor gene were analysed in a sample of 88 bipolar patients and 162 controls, all of Spanish origin. Statistical analyses revealed no overall allele or genotype associations with the disease. A haplotype analyses between the (GT)12-18/(CT)4-5 motif and a Cys23Ser variant of the 5-HT2C gene (which had previously been genotyped in the same sample) showed similar distributions between cases and controls. Only a slight increase of s-Ser23 haplotype was found in the subgroup of bipolar women with family history of psychiatric illness (OR=1.24 [95%CI: 1.12-1.38]).

Abstract
In the present study, genetic variation of the 5-HT5A receptor was analyzed in patients affected by affective disorders and healthy controls. The sample consisted of 181 patients with major depression, 88 patients with bipolar affective disorder (BP) and 157 unrelated controls (C), all of Spanish origin. Two polymorphisms (-19G/C and 12A/T) in the 5-HT5A receptor gene were analyzed by polymerase chain reaction amplification and subsequent enzyme digestion. No genotype, allele or haplotype differences were found when we compared patients and controls. When clinical variables were considered as possible tools for detecting genetic heterogeneity, no differences were found. Our results suggest that the polymorphisms analyzed in the 5-HT5A receptor gene do not play a major role in the pathogenesis of affective disorders.

Abstract
The 102-T/C polymorphism of the 5-HT(2A) receptor gene was analysed in 159 patients with major depression and 164 unrelated and healthy controls using a case-control design. Allele and genotype frequencies did not differ between cases and controls. No differences according to sex, age of onset, melancholia, suicidal behaviour or family history of psychiatric illness were found. However, genotype distributions significantly differed between patients with seasonal pattern in their episodes (MDS) and patients with no seasonal pattern (N-MDS) (chi(2) = 10.63; P = 0.004). A seasonal pattern was 7.57 times more frequent in 102C-allele carriers than in 102T homozygous (95.1% of patients MDS carried 102C-allele vs 72% of patients N-MDS (chi(2) = 9.45, df=1, P = 0.002; OR = 7.57 (95% CI: 1.65--48.08)). These results suggest that variation in the 5-HT2A receptor gene may play a role in the development of major depression with seasonal pattern and support the existence of a genetic and etiological heterogeneity underlying the diagnosis of major depression.

Abstract
UNLABELLED The attendance respiratory extracorporeal (AREC) is an oxygenation form for membrane extracorporeal with flow tidal and veno-venous cannula described by Chevalier et al. in 1990. We present our clinical experience so much with AREC in system veno-venous flow tidal as veno-arterial. From october of 1997 until the present time we have treated three patients by means AREC, in two patients with veno-venous system and in one veno-arterial. In all the cases bomb Collin-Cardio has been used with bladder for flow tidal and membrane of oxygenation of 0.8 m2, being inserted a system of alternative clamp of the branches of the circuit. The system AREC has been used in two patients with congenial diaphragmatic hernia, right in a case and left in the other one. The gestational age was of 38 and 36 weeks with a weight of 3,200 and 2,900 grams. Both patients were remitted from other centers by failure of the conventional treatment. In both cases the indication of AREC was the sharp deterioration of the general state with failure of the conservative treatment, being the previous oxygenation index of 109 and 112. The third patient precised veno-arterial AREC for ventricular failure during the correction of the congenital heart disease, this patient was 5 month old and the weight was 5,000 grams. The duration of AREC in the cases of congenital diaphragmatic hernia was of 14 and 10 days. In a patient the diaphragmatic hernia was corrected at the 55 hours of being in AREC. In the second case the hernia had been surgical corrected in another center. The exit of AREC in both cases carries out after a discreet improvement of the lung function. Both patients died at the 24 and 48 hours of the decannulation for cerebral hemorrhage and respiratory failure. The third patient stayed stable in veno-arterial AREC during 4 days, with hemodynamic support of 130 ml/kg/min, retiring the support to present absence of cerebral activity. CONCLUSIONS With the derived limitations of the extreme severity of the treated cases and the current phase of beginning of the AREC team, we think that it is a useful and available technique in our country, for the handling of patient with cardiorespiratory failure while waiting for improvement of their base pathology.

Abstract
OBJECTIVE The aim of this study was to evaluate the results of high frequency ventilation (HFV) used as a rescue strategy in newborn infants with severe lung disease who either failed conventional mechanical ventilation (CMV) or had an air block. PATIENTS AND METHODS From April 1995 to June 1998, 241 infants with severe lung disease and managed according to a common protocol of HFV used as a rescue strategy were prospectively evaluated in the nine participating level III Spanish Neonatal Intensive Care Units. The most frequent diagnoses were respiratory distress syndrome (119), meconium aspiration (24), pneumonia (19) and congenital diaphragm hernia (18). RESULTS Mean +/- SD gestational age and birth weight were 32.0 +/- 5.5 weeks and 1,187 +/- 1,071 g, respectively. All babies were previously manages with CMV for a mean of 59 hours. HFV was started at a mean postnatal age of 82 hrs, with a mean oxygenation index (OI) of 28.3 +/- 15.3 and an a/A DO2 of 0.10 +/- 0.08. Initial mean HFV settings were: mean airway pressure 12.8 +/- 3.4 mbar, frequency 8.3 +/- 1.4 Hz, amplitude 53 +/- 20 percent, tidal volume 2.2 +/- 0.7 ml/kg and FiO2 0.88 +/- 0.2. At two hours of HFV there was a significant increase in the mean PaO2 (from 48 to 80 mmHg), with a concomitant decrease in FiO2 (from 0.88 to 0.79), PaCO2 (from 60 to 46 mmHg) and OI (from 28 to 18). Mean a/A DO2 increased from 0.10 to 0.19; these changes remained similar thereafter. HFV was suspended after a mean of 95 hrs because of improvement in 70%, death in 19% and failure to improve the clinical condition in the remaining 19%. Intrahospital death rate was 32%. The following complications were observed: pneumothorax (10%), interstitial emphysema (4%), intraventricular hemorrhage grades III and IV (14.5%) and bronchopulmonary dysplasia (35%). CONCLUSIONS HFV is an effective rescue strategy that improves pulmonary gas exchange within two hours of its initiation.

Abstract
The microdialysis technique was used to examine the effect of the neurotoxin domoate, an analog of glutamic acid, on striatal dopamine activity. Our results show that the intracerebral administration of different concentrations of domoate (100 and 500 microM) produced increases in the extracellular levels of dopamine associated to decreases in the extracellular levels of its metabolites dihydroxyphenylacetate and homovanillate from rat striatum. These changes seem to be related according to a time sequence, indicating a possible effect on the metabolism of dopamine. Changes were also observed in locomotor activity (cycling behavior, sniffing around and chewing) in rats during the domoate infusion. The physiological mechanism by which domoate increased dopamine release remains to be worked out.

Abstract
OBJECTIVE Newborns with hypoplastic left heart syndrome (HLHS) included in the heart transplant program depend on continuous prostaglandin E1 (PGE1) perfusion for a prolonged period of time, which can result in various side effects. The objective of this study was to analyze the side effects derived from the use of PGE1 in newborns with HLHS who are awaiting heart transplantation. PATIENTS AND METHODS Fifteen newborns with HLHS included in a cardiac transplant program between January 1993 and August 1996 were studied. All received continuous endovenous perfusion of PGE1 from the time of diagnosis of the cardiopathy. RESULTS Thirteen patients were transplanted, with 6 dying in the operating room. Seven survived. Two patients died while waiting for a transplant. All presented short term side effects derived from the continuous perfusion of PGE1, including a slight fever and irritability. However, none of them presented apnea pauses. Cortical hyperostosis and anthral hyperplasia were observed in 13 (83.3%) and 12 (80%) cases, respectively, but in all transplanted cases regression of the anthral hyperplasia was seen after 6 months and regression of the cortical hyperostosis was seen after 12 months. CONCLUSIONS PGE1 was effective in maintaining the permeability of the ductus arteriosus. The side effects derived from the treatment were well tolerated. The appearance of cortical hyperostosis and anthral hyperplasia is related to the duration of the perfusion and these disappear in the weeks following the suspension of PGE1 treatment.

Abstract
The actions of Domoic Acid (Dom), a marine toxin, on the levels of serum TSH and thyroid hormones (T4 and T3) has been studied to determine if these actions could be mediated by the serotoninergic system. In all the experiments, adult male Wistar rats were used. The Dom dissolved in saline was administered via i.p. in doses of 0.5 and 1 mg/kg. The T4 and T3 concentrations were determined by enzimoinmunoassay and TSH concentration was determined by radioinmunoassay. The results show that Dom 1 mg/kg increases the serum T4 levels one hour after treatment and decreases these levels 2 and 3 hr after treatment. Dom 0.5 mg/kg decreased the serum T4 levels 2 and 3 hr after treatment. The concentrations of T3 in serum were unchanged by both doses of Dom. The concentration of TSH was increased by Dom. In order to study the possible mediation of the serotoninergic system in the effect of Dom on the hormone levels, PCPA, a tryptophan hydroxylase inhibitor, was administered i.p. 90 min before blood sampling. In this case, with both doses of Dom a decrease in the levels of both hormones occurred with respect to the PCPA group. These results indicate that the serotoninergic system could affect the actions of Dom on TSH and thyroid hormone secretion.

Abstract
During 1985-1994 period, 70,642 parasitological stool examinations were performed. The exam was made to each patient which presenting gastrointestinal symptoms or nutritional problems, specially in children. 59,960 out of the 70,642 examinations corresponded to 1 month--15 years old children, 4,280 to 16-30 years old individuals and 6.402 to up to 30 years old adults. The infection rates (x 100,000) were: Taenia sp., 86; Hymenolepis nana, 1,165; Diphyllobotrium sp., 4 and Hymenolepis diminuta, 1. In this period, 11 cases of infection by Taenia saginata were detected, and none Taenia sodium infection. Although infections rates by intestinal cesdodes were higher in males than females, in the Taenia sp. infection the difference was not statistical significative. Médico-veterinary control of animals slaughtered in abbatoirs and the improvement of sanitary conditions in the last two decades have contributed to the control of most of human intestinal cestodiases.
