RESUMO

There has been a significant increase in the development of interventions to improve the social competence and success of adolescents with autism spectrum disorder. The current investigation used direct observation and coding of social conversations as a rigorous method to further assess the efficacy of the Social Tools And Rules for Teens socialization intervention for adolescents with autism spectrum disorder in the context of a randomized controlled trial. A total of 35 adolescents with high-functioning autism spectrum disorder were randomized to either a treatment or waitlist control group. The 20-week group intervention took place once a week for 90 min per session. Brief video-recorded conversations between participants and unfamiliar, untrained peers were recorded at pre- and post-time points and coded for selected social behaviors (i.e. questions asked, positive facial expressions, and mutual engagement). Results revealed a significant Group × Time treatment effect for both questions asked and positive facial expressions. The findings support that the Social Tools And Rules for Teens intervention can positively impact specific, observable social behaviors through systematic coding of live social conversations within the context of a randomized controlled trial. This investigation is one of the first randomized controlled trials of a group socialization intervention to use systematic coding of live social conversations to assess social competence improvements.

RESUMO

Experiential learning is an essential process in the development of core social competencies. Unfortunately, adolescents with autism spectrum disorders often do not possess the prerequisite skillset and motivation to sustain the level of social immersion needed to benefit from this learning process. These persisting social vulnerabilities can limit their long-term relational success and associated quality of life, creating a need for comprehensive social programming. This paper describes a multi-component socialization intervention that simultaneously targets motivational, conceptual, and skill deficits using a hybrid experiential/didactic treatment approach. Evidence of social competence improvements was noted in survey and live conversational measures, indicating that the START program may hold promise as a method for improving the social success of participating adolescents with ASD.

RESUMO

BACKGROUND: Prior evidence suggests panic disorder (PD) is characterized by neurometabolic abnormalities, including increased brain lactate responses to neural activation. Increased lactate responses could reflect a general upregulation of metabolic responses to neural activation. However, prior studies in PD have not measured activity-dependent changes in brain metabolites other than lactate. Here we examine activity-dependent changes in both lactate and glutamate plus glutamine (glx) in PD. METHODS: Twenty-one PD patients (13 remitted, 8 symptomatic) and 12 healthy volunteers were studied. A single-voxel, J-difference, magnetic resonance spectroscopy editing sequence was used to measure lactate and glx changes in visual cortex induced by visual stimulation. RESULTS: The PD patients had significantly greater activity-dependent increases in brain lactate than healthy volunteers. The differences were significant for both remitted and symptomatic PD patients, who did not differ from each other. Activity-dependent changes in glx were significantly smaller in PD patients than in healthy volunteers. The temporal correlation between lactate and glx changes was significantly stronger in control subjects than in PD patients. CONCLUSIONS: The novel demonstration that glx responses are diminished and temporally decoupled from lactate responses in PD contradicts the model of a general upregulation of activity-dependent brain metabolic responses in PD. The increase in activity-dependent brain lactate accumulation appears to be a trait feature of PD. Given the close relationship between lactate and pH in the brain, the findings are consistent with a model of brain metabolic and pH dysregulation associated with altered function of acid-sensitive fear circuits contributing to trait vulnerability in PD.

RESUMO

BACKGROUND: Pregabalin is a structural analog of GABA, similar to gabapentin. It does not have a FDA indication for any psychiatric disorder in the USA. There has been one case report of the successful use of pregabalin as an augmenting agent in a patient with Bipolar Disorder (BD). In the present open label study, not subsidized by the manufacturer, the investigators prospectively evaluated the acute and maintenance efficacy of pregabalin as an adjunctive medication for a group of treatment refractory outpatients with BD. METHODS: Older adolescent and adult outpatients with any type of DSM-IV diagnosed BD, who were considered treatment nonresponders to multiple standard medications for BD, were treated with adjunctive pregabalin. The baseline mood state before initiation of pregabalin was compared to the mood state after an acute trial of pregabalin using the Clinical Global Impression-Bipolar Version Scale (CGI-BP). All acute responders were treated for a minimum of two months. Follow-up maintenance treatment data was obtained for the acute pregabalin responders for three years after the 18 month acute phase of the study. RESULTS: Fifty-eight total patients were treated adjunctively with pregabalin. Twenty-four (41%) were rated as acute responders. For the acute responders, pregabalin produced either a mood stabilizing effect, antidepressant effect or antimanic effect. Intolerable side-effects were the most common reason (79%) for a failed acute trial of pregabalin. None of the side effects resulted in serious medical complications. No patient abused pregabalin, and there were no adverse drug-drug interactions despite an average of 3.3 concurrent other psychiatric medications. The maintenance data revealed that 10 (42%) of the original 24 acute pregabalin responders were still taking pregabalin as an add-on medicine for an average of 45.2 months (range 42-48, SD: 2.35). LIMITATIONS: This study has an open label observation design. CONCLUSIONS: The results of this preliminary open study suggest that pregabalin is a safe and effective acute and maintenance adjunctive treatment for a significant number of treatment-resistant outpatients with any type of BPD. It appears to have mood stabilizing and antidepressant properties in addition to antimanic effects. Similar studies using a double-blind, randomly controlled design would be useful to confirm the reliability and validity of the results of this study.

RESUMO

BACKGROUND: Insomnia in patients with bipolar disorder (BD) can cause distress, daytime dysfunction, cognitive impairment, worsening of hypomanic/manic symptoms and increased suicide risk. Physicians often prescribe hypnotics for BD patients with insomnia although no hypnotic has a specific FDA indication for this use. In this study, the patterns of use, efficacy and safety of five nonbenzodiazepine hypnotics (NBZHs) were assessed in a large group of outpatients with BD. METHOD: A chart review was performed for all older adolescents and adult BD outpatients in a private outpatient clinic. Clinical data was collected for any patient who had ever been prescribed a NBZH for insomnia and included successful current use, past unsuccessful treatments, side effects, duration of use, concurrent psychiatric medications, and absence or presence of untoward events often associated with chronic use of hypnotics. RESULTS: A significant number of BD patients take NBZHs as needed or on a daily basis. Four NBZHs had adequate success rates; ramelteon was limited in efficacy. Some patients experienced satisfactory results from a NBZH after unsuccessful trials with one or more other NBZHs. About half of the current NBZH users are taking them on a daily long-term basis, and none of these patients have experienced unacceptable untoward events. About three quarters of the chronic NBZH users are taking antimanic medications concurrently, and less than half of the chronic users are taking antidepressants. LIMITATIONS: The results may not be generalizable to other BD populations. A control group was not included in the design. Chronic users of NBZHs were not asked to discontinue their NBZH in order to confirm indication for long-term use. CONCLUSIONS: Most NBZHs can be effective and safe agents for selected BD outpatients with episodic or chronic insomnia. Failure to respond to one or more NBZH does not preclude a satisfactory response to a different NBZH. Some BD patients who take maintenance antimanic agents also require NBZH treatment. Overactivation from antidepressant treatment does not contribute to chronic NBZH use in most BD patients.

RESUMO

Low-level-radioactive-waste (low-level-waste) sites, including those at various U.S. Department of Energy sites, frequently contain cellulosic waste in the form of paper towels, cardboard boxes, or wood contaminated with heavy metals and radionuclides such as chromium and uranium. To understand how the soil microbial community is influenced by the presence of cellulosic waste products, multiple soil samples were obtained from a nonradioactive model low-level-waste test pit at the Idaho National Laboratory. Samples were analyzed using 16S rRNA gene clone libraries and 16S rRNA gene microarray (PhyloChip) analyses. Both methods revealed changes in the bacterial community structure with depth. In all samples, the PhyloChip detected significantly more operational taxonomic units, and therefore relative diversity, than the clone libraries. Diversity indices suggest that diversity is lowest in the fill and fill-waste interface (FW) layers and greater in the wood waste and waste-clay interface layers. Principal-coordinate analysis and lineage-specific analysis determined that the Bacteroidetes and Actinobacteria phyla account for most of the significant differences observed between the layers. The decreased diversity in the FW layer and increased members of families containing known cellulose-degrading microorganisms suggest that the FW layer is an enrichment environment for these organisms. These results suggest that the presence of the cellulosic material significantly influences the bacterial community structure in a stratified soil system.
