Office versus Home-Based Family Therapy for Runaway, Alcohol Abusing Adolescents: Examination of Factors Associated with Treatment Attendance

There is a dearth of research examining treatment engagement and attendance among runaway youth and their families. Such research is needed in order to inform treatment providers on factors associated with engagement and maintenance of these difficult to engage families into counseling. This study examined differential treatment attendance for alcohol abusing runaway youth residing at a local shelter. A traditional office-based family systems approach, Functional Family Therapy (FFT), was compared to a non-traditional, home-based, multi-systemic family therapy approach, Ecologically Based Family Therapy (EBFT). As expected, treatment engagement and attendance was significantly higher for those assigned to EBFT (N = 37) compared to FFT (N = 40). Predictors of treatment attendance (income, family chaos, externalization problems and level of youth substance use) were examined within each treatment modality. Findings suggest that home-based (compared to office-based) treatment modalities may significantly increase treatment attendance and engagement of runaway youth and their families. Non-traditional forms of treatment may need to be considered in order to best meet the needs of highly chaotic and disorganized family systems.     

Development of an in vitro burn wound model

Healing of a deeper burn wound is a complex process that often leads to scar formation. Skin wound model systems are important for the development of treatments preventing scarring. The aim of this study is to develop a standardized in vitro burn wound model that resembles the in vivo situation. A burn wound (10 × 2 mm) was made in ex vivo skin and the skin samples were cultured at the air–liquid interface for 7, 14, and 21 days. Cells in the skin biopsies maintained their viability during the 21-day culture period. During culture, reepithelialization of the wound took place from the surrounding tissue and fibroblasts migrated into the wound area. Cells of the epithelial tongue and fibroblasts near the wound margin were proliferating. During culture, skin-derived antileukoproteinase and keratin 17 were expressed only in the epithelial tongue. Both collagen type IV and laminin were present underneath the newly formed epidermis, indicating that the basement membrane was restored. These results show that the burn wound model has many similarities to in vivo wound healing. This burn wound model may be useful to study different aspects of wound healing and testing pharmaceuticals and cosmetics on, e.g., migration and reepithelialization.     

Tau isoform expression in frontotemporal dementia without tau deposition

In many cases of sporadic frontotemporal dementia (FTD) and in FTD caused by tau mutations (FTDP-17) there is disruption of the normal splicing of tau leading to the aberrant expression of tau isoforms and neurodegeneration. This suggests a central role for tau in the pathogenesis of FTD. However, more than half the cases of sporadic FTD show no tau deposition. We question whether altered expression is also involved in the pathogenesis of tau-negative FTD. Real-time polymerase chain reaction was used to investigate tau isoform expression in tau-negative FTD and age-matched controls. There were no differences in total tau mRNA or 4R versus 3R isoform expression. Our study suggests that perturbed tau mRNA expression is unlikely to be involved in the pathogenesis of tau-negative FTD.     

D-cycloserine augmented exposure therapy for obsessive-compulsive disorder.

BACKGROUND: D-cycloserine (DCS), a glutamatergic partial N-methyl-d-aspartate (NMDA) agonist, can facilitate extinction learning related to cued fear in animals and humans. We predicted that DCS would accelerate obsession-related distress reduction in patients with obsessive-compulsive disorder (OCD) undergoing extinction-based exposure therapy. METHODS: We administered DCS (125 mg) or placebo in a double-blind fashion to individuals with OCD approximately 2 hours before each exposure session. RESULTS: D-cycloserine decreased both the number of exposure sessions required to achieve clinical milestones and the rate of therapy dropout. After four exposure sessions, patients in the DCS group reported significantly greater decreases in obsession-related distress compared with the placebo group; however, after additional sessions, the placebo group tended to catch up. CONCLUSIONS: D-cycloserine augmentation has the potential to increase the efficiency, palatability, and overall effectiveness of standard exposure therapy for OCD.
