Assessment of the effects of a parental intervention with mothers of children with internalizing problems

The present study assesses the effects of a semi-structured intervention held exclusively with mothers and its effects on internalizing problems, social skills of children, and positive and negative parenting practices. The single subject experimental design with three participants was adopted. The three mothers had, in baseline, children diagnosed with internalizing and externalizing problems. The instruments used were CBCL, RE-HSE-P, QRSH-Pais and PHQ-9, they were performed in baseline, pre-test, post-test, and follow-up assessments. The intervention held is characterized as semi-structured for it promotes the development of parental practices that are considered positive by the literature on behavior problems, however, contingently to the difficulties and demands of each case. The number of sessions performed for each case was 14, 15 and 17, which lasted about two hours each. The data were analyzed according to the instruments' norms and under the perspective of each singular case. The results found include remission of internalizing problems, increase in frequency of the children's social skills, increase in frequency of positive parental practices, and decrease in variability of negative parental practices. All the improvements were maintained on the six months follow-up, with the exception of variability on the negative parental practices of one client. Results are discussed in a context of mental health promotion and indicate the need for strategies to prevent internalizing problems in children.

Quality and safety of pet treats: assessment of the microbial safety and quality of pet treats

The aim of this study was to evaluate the hygienic and sanitary conditions of pettreats from an export industry. The occurrence of Salmonella, enumerated sulfite-reducing Clostridium (SRC), coagulase-positive Staphylococcus (CPS) and total(TC) and thermotolerant coliforms (TTC) was studied. Of the 108 samples ana-lyzed, 22 were contaminated by some microorganism. TC were detected at twosamples (3.5 × 101and 4.5 × 101colony-forming units [cfu]/g), SRC in 19 samples(1.0 × 101to 1.3 × 105cfu/g) and Salmonella spp. at only one sample; CPS andTTC were not detected. These findings indicate the microbiological safety of mostitems, except for a mix of dried bovine offal, with 1.3 × 105cfu/g of SRC, and onemix of dehydrated bovine viscera contaminated with Salmonella. The current pro-duction processes and the food safety management system are adequate to guar-antee the production of microbiologically safe foods, but that some improvementscan still be made with regard to cleaning and disinfection and hygiene training.
