Introduction:
Adoption, twin and family studies suggest that suicide behavior is familial and heritable. Both completed and attempted suicide appear to be transmitted in a familial form. Genetics and environment influences had been detected in various studies. But suicidal behavior suggests to be inherited independently from the mental disorders usually associated with it. While traditional statistics emphasizes inference and estimations, data mining emphasizes the fulfillment of a task such as classification, estimation, or knowledge discovery.
Objectives:The goal of this study was to determine in a large sample of suicide attempts which variables are associated with family history of attempted suicide.
Methods:In an emergency room, 539 adult suicide attempters were recruited. The two dichotomous dependent variables were family history of suicide attempt (10%) and of completed suicide (4%). Independent variables were 101 clinical variables explored with two data mining techniques: Random Forest and Forward Selection.
Results:A model for family history of completed suicide could not be developed. A classificatory model for family history of attempted suicide included the use of alcohol in the intent and family history of completed suicide, provide a sensitivity of 78.4%, a specificity of 98.7% and accuracy of 96.6%.
Conclusions:A classificatory model for family history of completed suicide could not be developed using data mining techniques. But it suggested that the use of alcohol in the intent and family history of completed suicide may be associated with familial attempted suicide.

Background and aims:
CYP2D6 metabolizes risperidone into 9-hydroxi-risperidone, as well as other drugs. CYP2D6 shows genetic polymorphism, and 6-8% of Caucasians are “slow metabolizers”. “Fast metabolizers” show lower plasma levels of risperidone and higher levels of 9-hydroxi-risperidone than “slow metabolizers”. The aim of this study is to collect information about the hypothetical relationship between metabolism phenotype and parameters related to sanitary resources utilization in patients treated with risperidone.
Methods:Plasma levels of risperidone and 9-hydroxi-risperidone were determined in 52 patients treated at the Acute Unit setting, to establish their metabolism phenotype. Patients were grouped as fast (n=11), slow (n=13) or intermediate metabolizers (n=28), according to risperidone/9-hydroxi-risperidone ratio logarithm and using eighty and twenty percentiles as cut-points. Hospitalizations, emergency services utilization and visits to community mental health center during two years were recorded in the three groups.
Results:Fast metabolizers showed a higher mean number of visits to community mental health centers (35.7 vs 24.8, fast and slow metabolizers respectively, p=0.667), a higher mean number of hospitalizations (2.45 vs 1.3, fast and slow metabolizers respectively; p=0.091), a longer mean length of hospitalizations (57.3 vs 47.6 days, fast and slow metabolizers respectively; p=0.581) and a higher number of visits to emergency services (2.45 vs 1, fast and slow metabolizers respectively; p=0.01), although differences only reached statistical significance in this last parameter.
Conclusions:In spite of methodological limitations (mainly the small sample size), the present study shows some preliminary evidence about the influence of pharmacogenetic factors on the evolution of psychotic patients treated with risperidone.

Introduction
Goodman expanded the conceptualization of addictions to embrace not only drug addiction but other behavioral addictions. In some cases, suicidal behaviour can be viewed as a behavioral addiction.
ObjectivesThe main objective of the present study is to analyze the relationships between major suicide repeaters (> or =5 lifetime suicide attempts) and measures of suicidal behaviour addiction.
AimsTo characterize major suicide repeaters.
MethodsSample and procedure: This is a transversal study of 954 suicide attempters (Montpellier, France). All suicide attempters were assessed using a protocol including: MINI (Axis I disorders), TPQ (personality traits) and BIS-10 (impulsivity), among others. Statistical Analyses: Comparisons between groups was made using logistic regression models with crude odds ratios and 95% confidence intervals.
ResultsMajor repeaters were more likely to be female and having low educational level than non-major repeaters (OR[95%]=6.95[3.19–15.10]; p < 0.0001; and OR[95%]=2.17[1.38–3.33]; p < 0.001, respectively). As compared with non-major repeaters, major repeaters more often met criteria for bipolar disorder (OR[95%]=1.82[1.22–2.74]; p < 0.05), anxiety disorders (OR[95%]=1.77[1.03–3.07]; p < 0.05) and eating disorders (OR[95%]=2.81[1.79–4.41]; p < 0.0001). Furthermore, compared with non-major repeaters, major repeaters were more frequently diagnosed with cigarette smoking (63.5% vs. 53.5%), alcohol use (29.3% vs. 25.4%) and substance use (15.4% vs. 13.2%), but none of them reached statistical significance. Finally, major repeaters, as compared with non-major repeaters, were more likely to score high in harm avoidance (OR[95%]=2.52[1.52–4.18];p < 0.001), BIS-10 global score (OR[95%]=2.09[1.25–3.47]; p < 0.05) and BIS-10 non-planning impulsiveness (OR[95%]=3.31[1.37–7.99]; p < 0.05).
ConclusionsOur preliminary results give partial support to the addictive hypothesis of suicidal behaviour.

Members of the genus Drepanocephalus are endoparasites of fish-eating birds of the families Phalacrocoracidae and Sulidae distributed across the Americas. Currently, Drepanocephalus contains three species, i.e. D. spathans (type species), D. olivaceus and D. auritus. Two additional species, D. parvicephalus and D. mexicanus were transferred to the genus Petasiger. In the current study, available DNA sequences of D. spathans, D. auritus and Drepanocephalus sp., were aligned with newly generated sequences of D. spathans and Petasiger mexicanus. Phylogenetic analyses inferred with three nuclear (LSU, SSU and ITS1, 5.8S, ITS2) and two mitochondrial (cox1, nad1) molecular markers showed that the sequences of D. spathans and D. auritus are nested together in a single clade with very low genetic divergence, with Petasiger mexicanus as its sister species. Additionally, P. mexicanus was not a close relative of other members of the genus Petasiger, showing that P. mexicanus actually belongs to the genus Drepanocephalus, suggesting the need to re-allocate Petasiger mexicanus back into the genus Drepanocephalus, as D. mexicanus. Morphological observations of the newly sampled individuals of D. spathans showed that the position of the testes is variable and testes might be contiguous or widely separated, which is one of the main diagnostic traits for D. auritus. Our results suggest that D. auritus might be considered a synonym of D. spathans and, as a result, the latter represents a species with a wide geographic range across the Americas, parasitizing both the Neotropical and the double-crested cormorant in Argentina, Brazil, Paraguay, Venezuela, Colombia, Mexico, USA and Canada.

Lolium rigidum L. (rigid ryegrass) is one of the most extensive and harmful weeds in winter cereal crops. A bioclimatic model for this species was developed using CLIMEX. The model was validated with records from North America and Oceania and used to assess the global potential distribution of L. rigidum under the current climate and under two climate change scenarios. Both scenarios represent contrasting temporal patterns of economic development and carbon dioxide (CO2) emissions. The projections under current climatic conditions indicated that L. rigidum does not occupy the full extent of the climatically suitable area available to it. Under future climate scenarios, the suitable potential area increases by 3·79% in the low-emission CO2 scenario and by 5·06% under the most extreme scenario. The model's projection showed an increase in potentially suitable areas in North America, Europe, South America and Asia; while in Africa and Oceania it indicated regression. These results provide the necessary knowledge for identifying and highlighting the potential invasion risk areas and for establishing the grounds on which to base the planning and management measures required.

Tylodelphys aztecae n. sp. (Digenea: Diplostomidae) is described from adult specimens obtained from the intestine of the pied-billed grebe (Podilymbus podiceps) and the metacercariae found in the body cavity of freshwater fishes of the families Goodeidae and Cyprinidae in eight localities across central and northern Mexico. The new species is mainly distinguished from the other four described species of Tylodelphys from the Americas (T. adulta, T. americana, T. elongata and T. brevis) by having a forebody slightly concave, a larger ventral sucker, two larger pseudosuckers and by having between 2 and 7 eggs in the uterus. Partial DNA sequences of the mitochondrial gene cytochrome c oxidase subunit I (cox1), and the internal transcribed spacers (ITS1+5.8S+ ITS2) of the ribosomal DNA, were generated for both developmental stages and compared with available sequences in GenBank of other congeners. The genetic divergence estimated among Tylodelphys aztecae n. sp. and other congeneric species varied from 12 to 15% for cox1, and from 3 to 11% for ITS. In contrast, the genetic divergence among metacercariae and adults of the new species was very low, ranging between 0 and 1% for cox1 and between 0 and 0.3% for ITS. Phylogenetic analyses inferred with both molecular markers using maximum likelihood and Bayesian inference placed the adults and their metacercariae in a single clade, confirming that both stages are conspecific. The morphological evidence and the genetic divergence, in combination with the reciprocal monophyly in both phylogenetic trees, support the hypothesis that the diplostomids found in the intestines of the pied-billed grebe bird and the body cavity from goodeid and cyprinid fishes in central and northern Mexico represent a new species.

Recently, bimetallic nanostructures and nanoalloys have received special interest due to their promising chemical and physical properties. Specifically, Cu-Ni nanoparticles have been investigated for biomedical and catalytic applications. This work reports the synthesis of alloys and bimetallic nanoparticles of CuxNi100-x (x = 20, 40, 50, 60 and 80) by sol-gel method, and their morphological, structural and magnetic characterization. A precursor material was prepared using a standard Pechini method and then CuNi nanoparticles were obtained by calcination treatments of the precursor in H2/N2atmosphere at 600 and 700°C for 15 minutes. The resulting nanoparticles were characterized by X-ray diffraction (XRD), which reveals that this method led to the formation of CuNi substitutional nanoalloys and bimetallic nanoparticles with good cristallinity related with the calcination temperatures and Cu:Ni weight ratios. Transmission electron microscopy (TEM) shows nearly monodisperse and uniform spherical nanoparticles with sizes between 40 and 70 nm. The magnetic properties were studied using SQUID magnetometry, according with these results, the CuNi nanoparticles showed a ferromagnetic behavior, the magnetization value increases as a function of the weight percentage of Ni.

Al65Cu15Co20 and Al67Cu13Co20 (% at.) alloys with composition near to the quasicrystalline decagonal phase was produced by melting in an induction furnace and solidified at room temperature. The structural characterization was carried out by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and scanning electron microscopy (SEM). For the structural model of decagonal quasicrsytals, it is important to know which crystalline phases have a structural relationship on the formation and decomposition of this type of phases. In the present investigation, the decagonal phase usually coexist with small amounts of the Al(Cu,Co) cubic phase of B2 type. Then, the quasicrystalline (QC) phase is outside of a single-phase region under equilibrium conditions at room temperature. DSC and TGA techniques showed the thermal stability of the alloy system up to 1000 °C.

Axenic trophozoites of Entamoeba histolytica strain HM1-IMSS grown in vitro in the presence of E-64, a potent irreversible inhibitor of cysteine proteinases, preserved their viability, their rate of replication, their resistance to complement, their haemolytic capacity and their ability to destroy target cells, despite complete inhibition of total cysteine proteinase activity. On the other hand, their erythrophagocytic capacity and their ability to decrease TER of MDCK cells was partially decreased. The same trophozoites injected into the portal vein of hamsters receiving a maintaining dose of E-64 failed to cause tissue damage and were rapidly eliminated. Our results suggest that amoebic cysteine proteinase activity is not required for amoebic functions in in vitro conditions, but that it becomes necessary for survival of trophozoites in in vivo conditions, whatever other role (if any) it may play in the parasite's virulence.

Propósito
Este estudio evaluó las medicaciones psiquiátricas y su letalidad potencial en una muestra representativa de intentos de suicidio.
Materiales y métodosDurante 1996-98, se estudiaron 563 intentos de suicidio en un hospital general en Madrid (España). Se utilizó sobredosis de medicación en 456 de los intentos (81%). La proporción entre la dosis tomada y la dosis de prescripción máxima recomendada se usó para evaluar la toxicidad de la medicación.
ResultadosLas benzodiacepinas fueron los fármacos utilizados más a menudo en la intoxicación voluntaria (65% de las sobredosis), seguido por los nuevos antidepresivos (11%), los antidepresivos tricíclicos (ATC) (10%) y los antipsicóticos (8%). Una sobredosis con cualquiera de estas tres últimas medicaciones psiquiátricas era significativamente más frecuente en los pacientes a quienes se prescribió esas medicaciones. Las sobredosis para ATC eran potencialmente letales en el 47% de los casos. Sin embargo, todos los pacientes que tomaron sobredosis de medicaciones psiquiátricas se recuperaron bien y fueron dados de alta sin secuelas.
DiscusiónEste estudio indica que las medicaciones psiquiátricas, particularmente las benzodiacepinas, los nuevos antidepresivos y los antipsicóticos, son relativamente seguras cuanto se utilizan para intoxicación voluntaria. Si los pacientes con enfermedades mentales no reciben tratamiento suficiente, hay un riesgo claro y documentado más alto de suicidio.
ConclusiónEs mejor prescribir medicaciones psiquiátricas, particularmente las nuevas, en lugar de negarlas debido a un temor exagerado a una sobredosis letal.

HIV and HTLV seroprevalence was determined by means of unlinked anonymous testing of 2144 sera, originally obtained from primary care patients by representative sampling of the Spanish population aged 15-39 years in 1996. HIV-1 seroprevalence was 4·3 per 1000 population in the 15–39 years age group [95% confidence interval (CI), 1·5–10·7] and 5·6 per 1000 (95% CI, 1·8–15·3) in the 20–39 years age group. Seroprevalence proved higher in males and urban residents. No antibodies to HIV-2 and HTLV-I were detected in any of the sera studied. However, presence of antibodies to HTLV-II was confirmed in one serum sample, while HTLV seroreactivity, though detected in another, could not be typed. The two HTLV-positive results equated to a seroprevalence of 1·9 per 1000 in the 20–39 years age group (95% CI, 0·3–8·6). HIV-1 seroprevalence was consistent with previous estimates yielded by back-calculation. The level of HTLV seroprevalence found suggests endemicity.
