Gender differences in adolescents with suicidal behaviour: Personality andpsychopathology

Diferencias de género en adolescentes con conducta suicida: Personalidad y psicopatología. Este estudio evalúa la relación entre el género, la personalidad, la psicopatología y la conducta suicida entre los adolescentes. Para ello, se diseñó un estudio transversal con adolescentes hospitalizados (N = 92) que presentaban conductas suicidas. Se recogieron características sociodemográficas y datos relacionados con la conducta suicida. Además, se evaluó la personalidad y la gravedad clínica mediante la administración del Inventario Clínico de Adolescentes de Millon (MACI). Los resultados revelaron que las dimensiones de personalidad más prevalentes para ambos géneros fueron Introversivo, Auto-punitivo, Pesimista, Oposicionista, Tendencia límite e Inhibido. Sin embargo, los hombres puntuaron más alto en Inhibido (p = 0,02, d de Cohen = 0,45) y las mujeres en Egocéntrica (p = 0,03, d de Cohen = 0,40). En cuanto a la gravedad clínica de los síndromes, las mujeres puntuaron más alto en Predisposición Delictiva (p = 0,04, d de Cohen = 0,45) y los hombres en Sentimientos Ansiosos (p = 0,02, d de Cohen = 0. 51), Afecto Depresivo (p = 0,04, d de Cohen = 0,41) y Tendencia Suicida (p = 0,03, d de Cohen = 0,37), y los hombres informaron con mayor frecuencia de Abuso en la Infancia (p < 0,001, d de Cohen = 0,70). Los resultados ponen de manifiesto la importancia de las intervenciones universales para promover un cambio de actitud hacia la búsqueda de ayuda psicológica, especialmente en los hombres, y la necesidad de diseñar tratamientos eficaces a medida para adquirir habilidades de gestión emocional para ambos génerosThis study evaluates the relationship between gender, personality, psychopathology and suicidal behaviour among adolescents. For this purpose, a cross-sectional study with adolescent inpatients (N = 92) displaying suicidal behaviour was designed. Sociodemographic characteristics and data related to suicidal behaviour were collected. In addition, personality and clinical severity were assessed by administering the Millon Adolescent Clinical Inventory (MACI). Results revealed that the most prevalent personality dimensions for both genders were Introversive, Self-demeaning, Doleful, Oppositional, Borderline tendency and Inhibited. However, men scored higher in Inhibited (p = 0.02, Cohen’s d = 0.45) and women in Egotistic (p = 0.03, Cohen’s d = 0.40). Concerning clinical severity of syndromes, women scored higher in Delinquent Predisposition (p = 0.04, Cohen’s d = 0.45) and men in Anxious Feelings (p = 0.02, Cohen’s d = 0.51), Depressive Affect (p = 0.04, Cohen’s d = 0.41) and Suicidal Tendency (p = 0.03, Cohen’s d = 0.37), with men reporting more frequently Childhood Abuse (p < 0.001, Cohen’s d = 0.70). Results highlight the importance of universal interventions to promote a change in attitudes towards seeking psychological help, specially in men, and the need to design effective tailored treatments to acquire emotional management skills for both gender

Physiological responses of coffee (Coffea arabica L.) plants to biochar application under water deficit conditions

Water deficit is one of the main abiotic stressors in crop production. The development of strategies to improve plant tolerance to water deficits has gained importance. Biochar application can be considered an alternative to mitigate abiotic stress. The use of coffee pulp to produce biochar could be a novel strategy for improving drought tolerance in coffee crops. Coffer plants cv. ‘Castillo’ were grown in pots or PVC pipes filled with silt loam soil in two separate experiments to evaluate the effect of coffee pulp biochar application on physiological responses under water deficit conditions. Four different biochar doses (0, 4, 8, and 16 t · ha-1) were used. A water deficit was imposed through progressive reduction irrigation (25%, 50%, 75%, and 90% of water lost via evapotranspiration). The leaf gas exchange, maximum quantum yield of PSII (Fv/Fm), biomass, and water status were measured. Reduced irrigation negatively affected the Fv/Fm, leaf gas exchange, biomass, and water status. Biochar (8 t ha-1) increased photosynthesis in both well-irrigated plants (6 µmol m-2 s-1) and with reduced irrigation (3.5 µmol m-2 s-1) compared to 0 t ha-1 biochar (reduced irrigation: 1.8 µmol m-2 s-1 and well irrigated: 3.9 µmol m-2 s-1). In conclusion, 8 t ha-1 biochar can be a recommended practice for coffee production, not only to capture carbon and reintroduce it to the soil, but also to alleviate the effects of moderate water deficit. In future investigations, biochar application can be evaluated as an alternative to soil management or coffee plant nutrition, and its interaction with drought stress scenarios

Associating Metrics of Hunting Effort with Hunting Rate: A Case Study with the Wild Boar Sus scrofa

Wild boar Sus scrofa populations have increased dramatically in recent decades throughout Europe. While hunting is widely used in management activities; it rarely has an important role in regulating and reducing wild boar populations. Therefore, increasing the efficiency of hunting is a compelling issue. In this study, we used a three-year dataset (2016–2018) on a wild boar population living in Campania (southern Italy) as a case study to explore how the hunting effort made in collective drive hunts affected the hunting rate, estimated as the number of individuals culled per day. We fitted a Linear Mixed Model, in which we included the number of wild boars culled per drive hunt as the dependent variable, and the number of beaters, shooters and dogs and the month during which hunting occurred as the predictors. A mean of 1.81 wild boars were culled per drive hunt. The number of culled animals per hunt increased with the increasing number of hunting dogs and with the progression of the hunting season (i.e., from October to December), whereas the number of beaters and shooters had no effect. Overall, we observed a low hunting rate. We suggest that adjusting the hunting calendar and reorganising wild boar collective hunts, e.g., through an appropriate management of the number and training of hunting dogs, are essential to increase the hunting rate. Our results can be useful for wildlife managers to enhance hunting contribution in counteracting the negative impact of wild boar

Consumer Perceptions of Fruit and Vegetable Origin, Growing Methods, and Willingness to Pay in Trinidad and Tobago Marketplaces: Implications for Extension Programming

Consumer behavior is a complex phenomenon encompassing internal, external, and situational factors. This study examined perceptions of market consumers about fruits and vegetables in Trinidad and Tobago in terms of produce origin, growing method, and willingness to pay. A stratified purposive sample of consumers at 14 unique market locations was surveyed to measure the three constructs and demographics. Descriptive statistics, correlational analysis, a ttest, and one-way analysis of variance were used to analyze the data. Findings revealed consumers have positive perceptions of locally grown produce and produce grown without chemicals. Findings also revealed a slight willingness to pay more for such characteristics. There were small to moderate correlations among the three constructs. Male and female perceptions of locally grown produce were significantly different, but no differences were found based on age. Extension educators working with producers who sell directly to consumers can utilize results from this study in working with clientele to tailor marketing and production strategies. Further research into social norms and perceived behavior control is recommended to better understand consumer behavior and help Extension better prepare stakeholders for success in the market places

West Nile virus transmission. results from the integrated surveillance system in Italy, 2008 to 2015

IIn Italy a national Plan for the surveillance of imported and autochthonous human vector-borne diseases (chikungunya, dengue, Zika virus disease and West Nile virus (WNV) disease) that integrates human and veterinary (animals and vectors) surveillance, is issued and revised annually according with the observed epidemiological changes. Here we describe results of the WNV integrated veterinary and human surveillance systems in Italy from 2008 to 2015. A real time data exchange protocol is in place between the surveillance systems to rapidly identify occurrence of human and animal cases and to define and update the map of affected areas i.e. provinces during the vector activity period from June to October. WNV continues to cause severe illnesses in Italy during every transmission season, albeit cases are sporadic and the epidemiology varies by virus lineage and geographic area. The integration of surveillance activities and a multidisciplinary approach made it possible and have been fundamental in supporting implementation of and/or strengthening preventive measures aimed at reducing the risk of transmission of WNV trough blood, tissues and organ donation and to implementing further measures for vector control

Life's Joke: Bergson, Comedy, and the Meaning of Laughter

The present essay argues that Bergson’s account of the comic can only be fully appreciated when read in conjunction with his later metaphysical exposition of the élan vital in Creative Evolution and then by the account of fabulation that Bergson only elaborates fully three decades later in The Two Sources of Morality and Religion. The more substantive account of the élan vital ultimately shows that, in Laughter, Bergson misses his own point: laughter does not simply serve as a means for correcting human behavior but is rather the élan vital’s vital summons, the demand of life itself, that human beings challenge their obligations, question their societal forms, and thereby create new and, for Bergson, more ideal forms of life and community

From bench to bedside: in vitro and in vivo evaluation of a neonate-focused nebulized surfactant delivery strategy.

BACKGROUND: Non-invasive delivery of nebulized surfactant has been a neonatology long-pursued goal. Nevertheless, the clinical efficacy of nebulized surfactant remains inconclusive, in part, due to the great technical challenges of depositing nebulized drugs in the lungs of preterm infants. The aim of this study was to investigate the feasibility of delivering nebulized surfactant (poractant alfa) in vitro and in vivo with an adapted, neonate-tailored aerosol delivery strategy. METHODS: Particle size distribution of undiluted poractant alfa aerosols generated by a customized eFlow-Neos nebulizer system was determined by laser diffraction. The theoretical nebulized surfactant lung dose was estimated in vitro in a clinical setting replica including a neonatal continuous positive airway pressure (CPAP) circuit, a cast of the upper airways of a preterm neonate, and a breath simulator programmed with the tidal breathing pattern of an infant with mild respiratory distress syndrome (RDS). A dose-response study with nebulized surfactant covering the 100-600\u2009mg/kg nominal dose-range was conducted in RDS-modelling, lung-lavaged spontaneously-breathing rabbits managed with nasal CPAP. The effects of nebulized poractant alfa on arterial gas exchange and lung mechanics were assessed. Exogenous alveolar disaturated-phosphatidylcholine (DSPC) in the lungs was measured as a proxy of surfactant deposition efficacy. RESULTS: Laser diffraction studies demonstrated suitable aerosol characteristics for inhalation (mass median diameter, MMD\u2009=\u20093\u2009\u3bcm). The mean surfactant lung dose determined in vitro was 13.7%\u2009\ub1\u20094.0 of the 200\u2009mg/kg nominal dose. Nebulized surfactant delivered to spontaneously-breathing rabbits during nasal CPAP significantly improved arterial oxygenation compared to animals receiving CPAP only. Particularly, the groups of animals treated with 200\u2009mg/kg and 400\u2009mg/kg of nebulized poractant alfa achieved an equivalent pulmonary response in terms of oxygenation and lung mechanics as the group of animals treated with instilled surfactant (200\u2009mg/kg). CONCLUSIONS: The customized eFlow-Neos vibrating-membrane nebulizer system efficiently generated respirable aerosols of undiluted poractant alfa. Nebulized surfactant delivered at doses of 200\u2009mg/kg and 400\u2009mg/kg elicited a pulmonary response equivalent to that observed after treatment with an intratracheal surfactant bolus of 200\u2009mg/kg. This bench-characterized nebulized surfactant delivery strategy is now under evaluation in Phase II clinical trial (EUDRACT No.:2016-004547-36)

Plants and traditional knowledge: An ethnobotanical investigation on Monte Ortobene (Nuoro, Sardinia)

<p>Abstract</p> <p>Background</p> <p>Most of the traditional knowledge about plants and their uses is fast disappearing as a consequence of socio-economic and land use changes. This trend is also occurring in areas that are historically exposed to very few external influences, such as Sardinia (Italy). From 2004 to 2005, an ethnobotanical investigation was carried out in the area of Monte Ortobene, a mountain located near Nuoro, in central Sardinia.</p> <p>Methods</p> <p>Data were collected by means of semi-structured interviews. All the records – defined as 'citations', i.e. a single use reported for a single botanical species by a single informant – were filed in a data base ('analytical table'), together with additional information: i.e. local names of plants, parts used, local frequencies, and habitats of plants, etc. In processing the data, plants and uses were grouped into general ('categories') and detailed ('secondary categories') typologies of use. Some synthetic indexes have also been used, such as Relative Frequency of Citation (RFC), Cultural Importance Index (CI), the Shannon-Wiener Index (H'), and Evenness Index (J).</p> <p>Results</p> <p>Seventy-two plants were cited by the informants as being traditionally used in the area. These 72 'ethnospecies' correspond to 99 botanical taxa (species or subspecies) belonging to 34 families. Three-hundred and one citations, 50 secondary categories of use, and 191 different uses were recorded, most of them concerning alimentary and medicinal plants.</p> <p>For the alimentary plants, 126 citations, 44 species, and 13 different uses were recorded, while for the medicinal plants, there were 106 citations, 40 species, and 12 uses. Few plants and uses were recorded for the remaining categories. Plants and uses for each category of use are discussed. Analyses of results include the relative abundance of botanical families, wild vs. cultivated species, habitats, frequency, parts of plant used, types of use, knowledge distribution, and the different cultural importance of the species in question.</p> <p>Conclusion</p> <p>The study provides examples of several interesting uses of plants in the community, which would seem to show that the custom of using wild plants is still alive in the Monte Ortobene area. However, many practices are no longer in use, and survive only as memories from the past in the minds of elderly people, and often only in one or just a few informants. This rapidly vanishing cultural diversity needs to be studied and documented before it disappears definitively.</p
