This study aims to assess whether mothers reporting high and low child abuse potential differ in their experiences of childhood abuse and use of defense mechanisms, and to examine factors which might predict child abuse potential. 120 pregnant mothers in their third trimester completed demographic questionnaires, trauma and abuse potential measures, and a semi-structured parenting interview, which was coded for defense mechanisms. Multivariate and univariate analyses of variance were conducted to determine group differences of mothers with high and low abuse potential. A stepwise linear regression was conducted to identify variables which significantly predicted abuse potential. Mothers reporting high abuse potential were found to have significantly greater emotional and physical childhood abuse experiences, greater immature defense use, and lower overall defensive functioning than mothers with low abuse potential. Emotional abuse and immature defense use significantly predicted total child abuse potential scores. Results are consistent with existing literature and provide a novel approach to understanding influences on child abuse potential including maternal history of childhood abuse and current defense mechanisms. These variables further serve as points of prevention and intervention for improving the negative outcomes associated with intergenerational risk for child abuse.

Handling a rodent disease outbreak in a facility can be a challenge. After the University of Colorado Denver Office of Laboratory Animal Resources enhanced its sentinel monitoring program, > 90% of the animal colonies housed in a vivarium at the Anschutz Medical Campus (with an area of 50,000 net ft(2)), serving the labs of > 250 principal investigators, tested positive for multiple infective agents including mouse parvovirus, fur mites, pinworms and epizootic diarrhea of infant mice. The authors detail the process by which they planned and executed a shutdown and a decontamination of the facility, which involved the rederivation or cryopreservation of > 400 unique genetically modified mouse lines. The authors discuss the aspects of the project that were successful as well as those that could have been improved.
