Procedural Justice in Resolving Family Disputes: Implications for Childhood Bullying
High levels of family conflict and poor family conflict resolution strategies are often associated with externalizing behaviors in children, including the behavior of bullying. Through family interactions, parents have the opportunity to convey a variety of messages to the child. Some of these messages are sent through the child’s appraisal of procedural justice, which refers to the judgments of fairness directed at the process by which a conflict is resolved. The current study investigated the relationship between appraisals of procedural justice in family conflict resolution and bullying among middle-school students. A sample of 1,910 sixth through eighth graders completed a self-report survey on school violence. Structural equation modeling revealed a significant relationship in which higher appraisals of procedural justice during family conflict resolution were associated with lower frequencies of bullying by the child. Furthermore, this relationship was partially mediated by the internalization of the parent’s conduct during the conflict resolution process. The current study extended the research literature addressing the relevance of procedural justice in child development. Implications of these findings and suggestions for future research are discussed
Assessing School and Student Predictors of Weapons Reporting
School violence and weapons at school are a major concern for community members, school administrators, and policy makers. This research examines both student-level and school-level variables that predict middle school students’ willingness to report a weapon at school under several reporting conditions. Results substantiate previous analyses of these data that student-level variables explain students’ willingness to report a weapon but extend these findings to include school climate variables that affect willingness to report (i.e., collective identity and conflict). School climate variables were also shown to influence reporting under conditions in which there would be consequences for the weapons-carrying student or for the reporting student; however, school climate was not found to influence anonymous reporting conditions. Although policies aimed at improving school climate may increase a student’s willingness to report and are important in their own right, improving a school’s climate may be a daunting task. This research, therefore, suggests that the most efficient way to encourage weapons reporting is to provide students with an anonymous way to report
Identity Orientation, Voice, and Judgments of Procedural Justice During Late Adolescence
Ileal mucosal bile acid absorption is increased in Cftr knockout mice
BACKGROUND: Excessive loss of bile acids in stool has been reported in patients with cystic fibrosis. Some data suggest that a defect in mucosal bile acid transport may be the mechanism of bile acid malabsorption in these individuals. However, the molecular basis of this defect is unknown. This study examines the expression of the ileal bile acid transporter protein (IBAT) and rates of diffusional (sodium independent) and active (sodium dependent) uptake of the radiolabeled bile acid taurocholate in mice with targeted disruption of the cftr gene. METHODS: Wild-type, heterozygous cftr (+/-) and homozygous cftr (-/-) mice were studied. Five one-cm segments of terminal ileum were excised, everted and mounted onto thin stainless steel rods and incubated in buffer containing tracer (3)H-taurocholate. Simultaneously, adjacent segments of terminal ileum were taken and processed for immunohistochemistry and Western blots using an antibody against the IBAT protein. RESULTS: In all ileal segments, taurocholate uptake rates were fourfold higher in cftr (-/-) and two-fold higher in cftr (+/-) mice compared to wild-type mice. Passive uptake was not significantly higher in cftr (-/-) mice than in controls. IBAT protein was comparably increased. Immuno-staining revealed that the greatest increases occurred in the crypts of cftr (-/-) animals. CONCLUSIONS: In the ileum, IBAT protein densities and taurocholate uptake rates are elevated in cftr (-/-) mice > cftr (+/-) > wild-type mice. These findings indicate that bile acid malabsorption in cystic fibrosis is not caused by a decrease in IBAT activity at the brush border. Alternative mechanisms are proposed, such as impaired bile acid uptake caused by the thick mucus barrier in the distal small bowel, coupled with a direct negative regulatory role for cftr in IBAT function
Feline low-grade alimentary lymphoma: an emerging entity and a potential animal model for human disease
Background: Low-grade alimentary lymphoma (LGAL) is characterised by the infiltration of neoplastic T-lymphocytes, typically in the small intestine. The incidence of LGAL has increased over the last ten years and it is now the most frequent digestive neoplasia in cats and comprises 60 to 75% of gastrointestinal lymphoma cases. Given that LGAL shares common clinical, paraclinical and ultrasonographic features with inflammatory bowel diseases, establishing a diagnosis is challenging. A review was designed to summarise current knowledge of the pathogenesis, diagnosis, prognosis and treatment of feline LGAL. Electronic searches of PubMed and Science Direct were carried out without date or language restrictions. Results: A total of 176 peer-reviewed documents were identified and most of which were published in the last twenty years. 130 studies were found from the veterinary literature and 46 from the human medicine literature. Heterogeneity of study designs and outcome measures made meta-analysis inappropriate. The pathophysiology of feline LGAL still needs to be elucidated, not least the putative roles of infectious agents, environmental factors as well as genetic events. The most common therapeutic strategy is combination treatment with prednisolone and chlorambucil, and prolonged remission can often be achieved. Developments in immunohistochemical analysis and clonality testing have improved the confidence of clinicians in obtaining a correct diagnosis between LGAL and IBD. The condition shares similarities with some diseases in humans, especially human indolent T-cell lymphoproliferative disorder of the gastrointestinal tract. Conclusions: The pathophysiology of feline LGAL still needs to be elucidated and prospective studies as well as standardisation of therapeutic strategies are needed. A combination of conventional histopathology and immunohistochemistry remains the current gold-standard test, but clinicians should be cautious about reclassifying cats previously diagnosed with IBD to lymphoma on the basis of clonality testing. Importantly, feline LGAL could be considered to be a potential animal model for indolent digestive T-cell lymphoproliferative disorder, a rare condition in human medicine

Identity Orientation, Voice, and Judgments of Procedural Justice During Late Adolescence
This study focused on the relationship between voice and judgments of procedural justice in a sample of older adolescents and examined potential moderating and mediating influences of identity orientation (personal, social, and collective) and negative emotional response. Participants read 1 of two different family conflict scenarios (voice and no voice) asking them to imagine themselves in a disagreement with their parents over grades and financial support. In the voice condition, parents were described as making their decision after listening to the participant’s input. In the no voice condition, parents were described as making their decision without listening to the participant’s input. The adolescents then judged the fairness of the parental decisions and responded to questions concerning their identity orientation. Findings indicate that in addition to replicating the effect of voice in a novel context, the present investigation found moderating effects of personal identity orientation on procedural fairness judgments. Additionally, negative emotional response partially mediated the relationship between voice and global judgments of procedural fairness
Cholestatic hepatitis C after chemotherapy containing rituximab in diffuse large B cell lymphoma
Rituximab is a chimeric anti-CD20 monoclonal antibody that is a widely used for the treatment of B cells non-Hodgkin lymphoma. The use of chemotherapy regimens containing rituximab in HCV-positive patients with non-Hodgkin lymphoma has been associated with liver dysfunction, but no cases of cholestatic hepatitis C were described. To our knowledge, this is the first case of cholestatic hepatitis C in an HCV-positive patient with diffuse large B-cell lymphoma describes in the literature. We discuss the pathogenetic mechanisms underlying this severe form of hepatitis and describe its evolution after antiviral treatment
