- Inflammation plays a central role in the development of neonatal brain injury. The alpha 7 nicotinic acetylcholine receptor (alpha 7nAChR) can modulate inflammation and has shown promising results as a treatment target in rodent models of adult brain injury. However, little is known about the role of the alpha 7nAChR in neonatal brain injury. Hypoxic-ischemic (HI) brain injury was induced in male and female C57BL/6 mice, alpha 7nAChR knock-out (KO) mice and their littermate controls on postnatal day (PND) 9-10. C57BL/6 pups received i.p. injections of alpha 7nAChR agonist PHA 568487 (8 mg/kg) or saline once daily, with the first dose given directly after HI. Caspase-3 activity and cytokine mRNA expression in the brain was analyzed 24 h after HI. Motor function was assessed 24 and 48 h after HI, and immunohistochemistry was used to assess tissue loss at 24 h and 7 days after HI and microglial activation 7 days after HI. Activation of alpha 7nAChR with the agonist PHA 568487 significantly decreased CCL2/MCP-1, CCL5/RANTES and IL-6 gene expression in the injured brain hemisphere 24 h after HI compared with saline controls in male, but not female, pups. However, alpha 7nAChR activation did not alter caspase-3 activity and TNF alpha, IL-1 beta and CD68 mRNA expression. Furthermore, agonist treatment did not affect motor function (24 or 48 h), neuronal tissue loss (24 h or 7 days) or microglia activation (7 days) after HI in either sex. Knock-out of alpha 7nAChR did not influence neuronal tissue loss 7 days after HI. In conclusion, targeting the alpha 7nAChR in neonatal brain injury shows some effect on dampening acute inflammatory responses in male pups. However, this does not lead to an effect on overall injury outcome.

Tidskriftsartikel (refereegranskat)abstract
- The global hydrological cycle is characterized by complex interdependencies and self-regulating feedbacks that keep water in an ever-evolving state of flux at local, regional, and global levels. Increasingly, the scale of human impacts in the Anthropocene is altering the dynamics of this cycle, which presents additional challenges for water governance. Earth system law provides an important approach for addressing gaps in governance that arise from the mismatch between the global hydrological cycle and dispersed regulatory architecture across institutions and geographic regions. In this article, we articulate the potential for Earth system law to account for core hydrological problems that complicate water governance, including delay, redistribution, intertwinements, permanence, and scale. Through merging concepts from Earth system law with existing policy and legal principles, we frame an approach for addressing hydrological problems in the Anthropocene and strengthening institutional fit between established governance systems and the global hydrological cycle. We discuss how such an approach can be applied, and the challenges and implications for governing water as a cycle and complex social-hydrological system, both in research and practice.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundNonsuicidal self-injury (NSSI) is common in adolescents. Emotion dysregulation has been identified as a core mechanism in the development and maintenance of NSSI and it is therefore an important target when addressing NSSI. The pathogenic connection between different kinds of childhood abuse, difficulties in emotion regulation and NSSI needs further investigation. The objective of this study was to examine whether difficulties with emotion regulation and trauma symptoms, separately and together, mediate the relationships between sexual, physical and emotional abuse and NSSI. MethodCross-sectional data was collected from 3,169 adolescent high-school students aged 16-19 years (M = 18.12, SD = 0.45). Data from self-reported experiences of childhood abuse, current difficulties with emotion regulation (measured with the Difficulties with Emotion Regulation Scale, DERS-16) and trauma symptoms (measured with the Trauma Symptom Checklist for Children, TSCC), and NSSI were collected. Structural Equation Modeling (SEM) was used to test the proposed relationships between variables. ResultsThe prevalence of life-time NSSI was 27.4%. Prevalence of reported childhood abuse was 9.2, 17.5, and 18.0% for sexual, physical, and emotional abuse, respectively. Childhood abuse, difficulties with emotion regulation and trauma symptoms exhibited significant positive associations with NSSI in adolescents. Emotional dysregulation and trauma symptoms were both found to mediate the relationship between childhood abuse and NSSI. Latent variable models were found to fit data well. ConclusionResults indicate that increased levels of emotional dysregulation and trauma symptoms in relation to childhood abuse contribute to the increased risk of NSSI. Further, results point to some aspects of emotional dysregulation and trauma symptoms being more important in this regard. Clinical implications are discussed.

- Objective: To examine the associations between child physical abuse executed by a parent or caretaker and self-rated health problems/risk-taking behaviors among teenagers. Further to evaluate concurrence of other types of abuse and how these alone and in addition to child physical abuse were associated with bad health status and risk-taking behaviors.Methods: A population-based survey was carried out in 2008 among all the pupils in 2 different grades (15 respectively 17 years old) in Sodermanland County, Sweden (n = 7,262). The response rate was 81.8%. The pupils were asked among other things about their exposure to child physical abuse, exposure to parental intimate violence, bullying, and exposure to being forced to engage in sexual acts. Adjusted analyses were conducted to estimate associations between exposure and ill-health/risk-taking behaviors.Results: Child physical abuse was associated with poor health and risk-taking behaviors with adjusted odds ratios (OR) ranging from 1.6 to 6.2. The associations were stronger when the pupils reported repeated abuse with OR ranging from 2.0 to 13.2. Also experiencing parental intimate partner violence, bullying and being forced to engage in sexual acts was associated with poor health and risk-taking behaviors with the same graded relationship to repeated abuse. Finally there was a cumulative effect of multiple abuse in the form of being exposed to child physical abuse plus other types of abuse and the associations increased with the number of concurrent abuse.Conclusions: This study provides strong indications that child abuse is a serious public health problem based on the clear links seen between abuse and poor health and behavioral problems. Consistent with other studies showing a graded relationship between experiences of abuse and poor health/risk-taking behaviors our study shows poorer outcomes for repeated and multiple abuse. Thus, our study calls for improvement of methods of comprehensive assessments, interventions and treatment in all settings where professionals meet young people.

- Minor child physical abuse has decreased in Sweden since 1979, when a law banning corporal punishment of children was passed, but more serious forms have not decreased. The aim of this study was to examine risk and background factors in cases of severe child abuse reported to the police. Files from different agencies (e.g., Social services, Adult and Child psychiatry and Pediatric clinic) for 20 children and 34 caretakers were studied. An accumulation of risk factors was found. It is concluded that when the following four factors are present, there is a risk for severe child abuse: 1) a person with a tendency to use violence in conflict situations; 2) a strong level of stress on the perpetrator and the family; 3) an insufficient social network that does not manage to protect the child; 4) a child that does not manage to protect him or herself. Thus, multiple sources of information must be used when investigating child abuse.

- Background: Child physical abuse (CPA) is an extensive public health problem because of its associations with poor health outcomes. The aim of this study was to examine which of the background factors of CPA committed by a parent or other caregiver relates to self-reported poor health among girls and boys (13; 15 and 17 years old): perpetrator, last year exposure; severity and frequency; socioeconomic load and foreign background.Methods: In a cross-sectional study in a Swedish county (n = 8024) a path analysis was performed to evaluate a model where all background variables were put as predictors of three health-status variables: mental; physical and general health problems. In a second step a log linear analysis was performed to examine how the distribution over the health-status categories was different for different combinations of background factors.Results: Children exposed to CPA reported poor health to a much higher extent than those who were not exposed. In the path analysis it was found that frequency and severity of abuse (boys only) and having experienced CPA during the last year, was significantly associated with poor health as well as socioeconomic load in the families. Foreign background was significantly negatively associated with all three health indicators especially for girls. Neither mother nor father as perpetrator remained significant in the path analysis, while the results from the log linear analyses showed that mother-abuse did in fact relate to poor general health and mental as well as physical health problems among boys and girls. Father-abuse was associated with poor mental health if severe abuse was reported. Poor mental health was also associated with mild father-abuse if exposure during the last year was reported.Conclusion: Despite the limitations that cross-sectional studies imply, this study provides new knowledge about factors associated with poor health among physically abused children. It describes details of CPA that have significant associations to different aspects of poor health and thus what needs to be addressed by professionals within mental health providers and social services. Understanding how different factors may contribute to different health outcomes for exposed children is important in future research and needs further studies.

- Aim: To examine prevalence rates of child physical abuse perpetrated by a parent/caretaker, abuse characteristics and the extent of disclosures. Methods: A population-based survey was carried out in 2008 amongst all the pupils in three different grades (n = 8494) in schools in Sodermanland County, Sweden. The pupils were asked about their exposure to violence and their experiences of parental intimate-partner violence. Data were analysed with bi- and multivariate models and a comparison between means of accumulating risk factors between three groups were performed. Results: A total of 15.2% of the children reported that they had been hit. There were strong associations between abuse and risk factors and there was a dose-response relationship between risks and reported abuse. It was shown that children who reported parental intimate-partner violence were at a considerably higher risk for abuse than other children and that only 7% of the children exposed to violence had disclosed this to authorities. Conclusion: Even though child abuse in Sweden has decreased markedly during the last 40 years, violence against children is still a considerable problem. It is a challenge to develop methods of assessment and interventions that will ensure that the violence and its underlying causes are directly addressed.

- Aim: To investigate the characteristics of severe abuse of children and possible differences in comparison with less severe abuse. Method: Cases of abuse reported to the police within a single police district (n = 142) in Sweden were studied. The severe cases were compared to all the remaining cases. Results: Severe abuse constituted 14% of the total cases and was reported by agencies to a greater degree than minor cases. The suspected perpetrators were socially disadvantaged people in both groups. Half of the most serious cases led to conviction in the courts, compared to 8% in the reference group. The children who had been subjected to abuse were often already known to social services and reports of child abuse had frequently been made. Conclusion: In comparison between cases of severe and minor child abuse reported to the police, the results did not show any crucial differences except the pattern of reporting and a higher occurrence of prosecution/conviction in the severe cases. This finding places a responsibility on agencies outside of the justice system to consider all cases of reported abuse as serious warning signals and to make independent evaluations to identify risks and the possible need for child protection.
