The prevalence and correlates of childhood trauma in patients with early psychosis

Objective: To describe the prevalence and demographic, clinical and functional correlates of childhood trauma in patients attending early psychosis clinics. Method: Participants were recruited from outpatients attending four early psychosis services. Exposure to childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Psychopathology was measured using the Positive and Negative Syndrome Scale and the Depression, Anxiety and Stress Scale. Social and vocational functioning and substance use were also assessed. Results: Over three-quarters of the 100 patients reported exposure to any childhood trauma. Emotional, physical and sexual abuse were reported by 54%, 23% and 28% of patients, respectively, while 49% and 42% of patients reported emotional and physical neglect, respectively. Female participants were significantly more likely to be exposed to emotional and sexual abuse. Exposure to childhood trauma was correlated with positive psychotic symptoms and higher levels of depressive, anxiety and stress symptoms; however, it had no impact on social or vocational functioning or recent substance use. Conclusion: Exposure to childhood trauma was common in patients with early psychosis, and associated with increased symptomatology. Existing recommendations that standard clinical assessment of patients with early psychosis should include inquiry into exposure to childhood trauma are supported.

Does gender moderate the relationship between polydrug use and sexual risk-taking among Australian secondary school students under 16 years of age?

Introduction and Aims This study examines the association of alcohol and polydrug use with risky sexual behaviour in adolescents under 16 years of age and if this association differs by gender. Design and Methods The sample consisted of 5412 secondary school students under 16 years of age from Victoria, Australia. Participants completed an anonymous and confidential survey during class time. The key measures were having had sex before legal age of consent (16 years), unprotected sex before 16 (no condom) and latent-class derived alcohol and polydrug use variables based on alcohol, tobacco, cannabis, inhalants and other illegal drug use in the past month. Results There were 7.52% and 2.55% of adolescents who reported having sex and having unprotected sex before 16 years of age, respectively. After adjusting for antisocial behaviours, peers' drug use and family and school risk factors, girls were less likely to have unprotected sex (odds ratio = 0.31, P = 0.003). However, the interaction of being female and polydrug use (odds ratio = 4.52, P = 0.004) was significant, indicating that girls who engaged in polydrug use were at higher risk of having unprotected sex. For boys, the effect of polydrug use was non-significant (odds ratio = 1.44, P = 0.310). Discussion and Conclusions For girls, polydrug use was significantly associated with unprotected sex after adjusting for a range of risk factors, and this relationship was non-significant for boys. Future prevention programs for adolescent risky sexual behaviour and polydrug use might benefit from a tailored approach to gender differences.

Working Ethically in Child Protection

Rather than a single focus on assessing risk and diagnosing deficit, this book recognises that our child protection systems bear down disproportionately on those from disadvantaged and marginalised communities and argues that what is needed is real support and practical assistance for poor and vulnerable parents and children. It uses real-world case examples to illustrate the relevant ethical and practice principles, and ways in which students and practitioners can practise ethically when dealing with complex, multi-faceted issues.

Caution, helping may be hazardous: Client abuse, threats and assaults

The shooting of a social worker by a client on the Gold Coast in 1991 graphically illustrated the issue of physical assaults and violence by service users against social workers. In this article we look at the incidence of physical assault, threats of violence, abuse of agency property and verbal abuse to social and other welfare workers by clients, using data from a survey in Melbourne. We then look at probable causes of menacing behaviour, such as issues involved in work with involuntary clients' and we discuss options for preventing and coping with violence and abuse in the welfare work place.

Screening for partner violence among family mediation clients: Differentiating types of abuse

Family mediation is mandated in Australia for couples in dispute over separation and parenting as a first step in dispute resolution, except where there is a history of intimate partner violence. However, validation of effective well-differentiated partner violence screening instruments suitable for mediation settings is at an early phase of development. This study contributes to calls for better violence screening instruments in the mediation context to detect a differentiated range of abusive behaviors by examining the reliability and validity of both established scales, and newly developed scales that measured intimate partner violence by partner and by self. The study also aimed to examine relationships between types of abuse, and between gender and types of abuse. A third aim was to examine associations between types of abuse and other relationship indicators such as acrimony and parenting alliance. The data reported here are part of a larger mixed method, naturalistic longitudinal study of clients attending nine family mediation centers in Victoria, Australia. The current analyses on baseline cross-sectional screening data confirmed the reliability of three subscales of the Conflict Tactics Scale (CTS2), and the reliability and validity of three new scales measuring intimidation, controlling and jealous behavior, and financial control. Most clients disclosed a history of at least one type of violence by partner: 95% reported psychological aggression, 72% controlling and jealous behavior, 50% financial control, and 35% physical assault. Higher rates of abuse perpetration were reported by partner versus by self, and gender differences were identified. There were strong associations between certain patterns of psychologically abusive behavior and both acrimony and parenting alliance. The implications for family mediation services and future research are discussed.

Human parvovirus infections during pregnancy : Special reference to the child-care employees

Human parvovirus B19 (B19V) is known to cause anemia, hydrops fetalis, and fetal death especially during the first half of pregnancy. Women who are in occupational contact with young children are at increased risk of B19V infection. The role of the recently discovered human parvovirus, human bocavirus (HBoV), in reproduction is unknown. The aim of this research project was to establish a scientific basis for assessing the work safety of pregnant women and for issuing special maternity leave regulations during B19V epidemics in Finland. The impact of HBoV infection on the pregnant woman and her fetus was also defined. B19V DNA was found in 0.8% of the miscarriages and in 2.4% of the intrauterine fetal death (IUFD; fetal death after completed 22 gestational weeks). All control fetuses (from induced abortions) were B19V-DNA negative. The findings on hydropic B19V DNA-positive IUFDs with evidence of acute or recent maternal B19V infection are in line with those of previous Swedish studies. However, the high prevalence of B19V-related nonhydropic IUFDs noted in the Swedish studies was mostly without evidence of maternal B19V infection and was not found during the third trimester. HBoV was not associated with miscarriages or IUFDs. Almost all of the studied pregnant women were HboV-IgG positive, and thus most probably immune to HBoV. All preterm births, perinatal deaths, smallness for gestational age (SGA) and congenital anomaly were recorded among the infants of child-care employees in a nationwide register-based cohort study over a period of 14 years. Little or no differences in the results were found between the infants of the child-care employees and those of the comparison group. The annual B19V seroconversion rate was over two-fold among the child-care employees, compared to the women in the comparison group. The seropositivity of the child-care employees increased with age, and years from qualification/joining the trade union. In general, the child-care employees are not at increased risk for adverse pregnancy outcome. However, at the population level, the risk of rare events, such as adverse pregnancy outcomes attributed to infections, could not be determined. According to previous studies, seronegative women had a 5 10% excess risk of losing the fetus during the first half of their pregnancy, but thereafter the risk was very low. Therefore, an over two-fold increased risk of B19V infection among child-care employees is considerable, and should be taken into account in the assessment of the occupational safety of pregnant women, especially during the first half of their pregnancy.

Chinese immigrants to Finland: A qualitative study of housing, employment, access to health care and child care as sociological dimensions in their settlement process

The Master’s thesis is qualitative research based on interviews of 15 Chinese immigrants to Finland in order to provide a sociological perspective of the migration experience through the eyes of Chinese immigrants in the Finnish social welfare context. This research is mainly focused upon four crucial aspects of life in the settlement process: housing, employment, access to health care and child care. Inspired by Allardt’s theoretical framework ‘Having, Loving and Being’, social relationships and individual satisfaction are examined in the case of Chinese interviewees dealing with the four life aspects. Finland was not perceived as an attractive migration destination for most Chinese interviewees in the beginning. However, with longer residence in Finland, the Finnish social welfare system gradually became a crucial appealing factor in their permanent settlement in Finland. And meanwhile, social responsibility of attending their old parents in China, strong feelings of being isolated in Finland, and insufficient integration into the Finnish society were influential factors for their decision of returning to China. Social relationships with personal friends, migration brokers, schools, employers and family relatives had great influences in the four life aspects of Chinese immigrants in Finland. The social relationship with the Finnish social welfare sector is supportive to Chinese immigrants, but Chinese immigrants do not heavily rely on Finnish social protection. The housing conditions were greatly improved over time while the upward mobility in the Finnish labour market was not significant among Chinese immigrants. All Chinese immigrants were satisfied with their current housing by the time I interviewed them while most of them had subjective feelings of being alienated in the Finnish labour market, which seriously prevented them from integrating into the Finnish society. In general, Chinese immigrants were satisfied with the low cost of accessing the Finnish public health care services and affordable Finnish child day care services and financial subsidies for children from the Finnish social welfare sector. This research also suggests that employment is the central basis in well-being. Support from the Finnish social welfare sector can improve the satisfaction levels among immigrants, especially when it mitigates the effects of low-paid employment. As well, my empirical study of Chinese immigrants in Finland shows that Having (needs for materials), Loving (needs for social relations) and Being (needs for social integration) are all involved in the four concrete aspects (housing, employment, access to health care and child care).

Dung as a potential medium for inter-sexual chemical signaling in Asian elephants (Elephas maximus)

Chemical signaling is a prominent mode of male-female communication among elephants, especially during their sexually active periods. Studies on the Asian elephant in zoos have shown the significance of a urinary pheromone (Z7-12:Ac) in conveying the reproductive status of a female toward the opposite sex. We investigated the additional possibility of an inter-sexual chemical signal being conveyed through dung. Sixteen semi-captive adult male elephants were presented with dung samples of three female elephants in different reproductive phases. Each male was tested in 3 separate trials, within an interval of 1-3 days. The trials followed a double-blind pattern as the male and female elephants used in the trials were strangers, and the observer was not aware of the reproductive status of females during the period of bioassays. Males responded preferentially (P < 0.005), in terms of higher frequency of sniff, check and place behavior toward the dung of females close to pre-ovulatory period (follicular-phase) as compared to those in post-ovulatory period (luteal-phase). The response toward the follicular phase samples declined over repeated trials though was still significantly higher than the corresponding response toward the non-ovulatory phase in each of the trials performed. This is the first study to show that male Asian elephants were able to distinguish the reproductive phase of the female by possibly detecting a pre-ovulatory pheromone released in dung.

Evaluación de semilla sexual hibrida de papa (Solanum tuberosum L.) provenientes del Centro Internacional de la Papa e India en la zona de Miraflor, Esteli

Con el objetivo de seleccionar progenies promisorias de semilla sexual de papa, procedentes del CIP (11) y Programa de la India (3) se estableció este ensayo el 21 de septiembre de 1994, utilizando un diseño de Bloques Completos al Azar (BCA) con cuatro repeticiones, en la estación experimental del Instituto Nicaragüense de Tecnología Agropecuaria (INTA-RB-3), ubicada a 1 350 msnm, humedad relativa del 91 por ciento, temperatura promedio mínima 15 °C/máx 26 °C, cuyos suelos son de textura franca bien drenada, medianamente profundo a profundo, con una precipitación durante el ensayo de 622 mm. Los resultados obtenidos muestran que todas las progenies híbridas enviadas por el CIP mostraron buena velocidad de emergencia en especial SERRANA x LT-7, con respecto a los lubridos de la India. En general el porcentaje de sobrevivencia fue mayor del 80 por ciento para la mayoría de las progenies el cual es un índice aceptable, a excepción de 104.12 LB x TS-4.En la altura final de la planta no hubieron diferencias significativas entre híbridos, solo fueron superiores a KATADIN x TS-10. En cuanto al rendimiento, la progenie HPS­ II/67 mostró ser superior a las demás con 6.2 kg/m2. El número total de tubérculos por metro cuadrado {740) y tubérculos por planta (7) fue superior en la progenie TS-6 x TPS-67. Las progenies de ambos programas mostraron rendimientos por metro cuadrado de más del 50 por ciento con tubérculos mayores de 5 gramos. No se presentó incidencia de virus para ambas progenies, las tres progenies provenientes del Programa de la India presentaron mayor resistencia a tizón tardío (Phytophthora infestans, Mont. D.bary).

Evaluacion de diferentes niveles de fertilizantes NPK en la produccion de minituberculos de papa (Solanum tuberosum L.) en semillero para la producción comercial, proveniente de semilla sexual, variedad ATZIMBA

La papa es una fuente de alimentación importante a nivel mundial, en Nicaragua los altos costos de importación de semilla de buena calidad, tiene como efecto, la dificultad de los productores de aumentar áreas de siembra y el bajo consumo con respecto a otros países por el costo de este producto. La falta de un programa nacional de producción de semilla contribuye al problema, ya que muchos productores no tienen acceso a semilla, pero al introducir la semilla botánica de papa para producción de minituberculos, hace que el productor demande nuevos conocimientos, por tanto hay que desarrollarlos, uno de estos conocimientos es la dosis de fertilización adecuada en semillero de papa para la producción de minituberculos. Existen estudios en otros países como Perú, pero no son adaptables a nuestras condiciones, por tal motivo se estableció un ensayo en el Mojón, Jinotega, el cual comprendió de septiembre a diciembre del 2002, el diseño utilizado fue el de Bloques Completos al Azar (BCA), donde se evaluaron cinco dosis de fertilizantes. El área experimental fue de 105 m2, la comparación de medias se realizo por Duncan al 0.05 de probabilidad. Los objetivos del ensayo fueron: objetivo general: Evaluar el efecto de distintos niveles de fertilización sobre la producción de mini tubérculos de papa (Solanum tuberosum L.) en semillero, proveniente de semilla sexual o semilla verdadera. Objetivos específicos: Estudiar el efecto de diferentes dosis de fertilizantes en almacigo para la producción de minituberculos de papa, determinar la dosis con las que se obtienen los mejores rendimientos en la producción de minituberculos de papa, y realizar un análisis Beneficio–Costo de los resultados obtenidos para determinar cual es el tratamiento que económica y productivamente es el más rentable. Los parámetros evaluados fueron: altura de plantas, plantas cosechadas, cuatro categorías de peso de tubérculos y número de tubérculos totales por hectárea, además el rendimiento de minitubérculos de papa. No se encontró evidencia estadísticas que alguna dosis aumente el numero de tubérculos por hectárea, pero, se demostró que la aplicación de 300 a 450 kilogramos de urea, 270 a 420 kilogramos del fertilizante 18-46-00 y 80 a 130 kilogramos de sulfato de amonio aumenta el rendimiento en peso de minitubérculos, y la ganancia de los productores aumenta de 133 000 a 139 300 córdobas por hectárea. Aplicaciones mayores de fertilizantes causan perdidas hasta en 41 600 córdobas por hectárea con respecto a la aplicación de los productores.
