This paper presents a pilot study of a brief, group-based, cognitive-behavioural intervention for anxiety-disordered children. Five children (aged 7 to 13 years) diagnosed with a clinically significant anxiety disorder were treated with a recently developed 6-session, child-focused, cognitive-behavioural intervention that was evaluated using multiple measures (including structured diagnostic interview, self-report questionnaires and behaviour rating scales completed by parents) over four follow-up occasions (posttreatment, 3-month follow-up, 6-month follow-up and 12-month follow-up). This trial aimed to (a) evaluate the conclusion suggested by the research of Cobham, Dadds, and Spence (1998) that anxious children with non-anxious parents require a child-focused intervention only in order to demonstrate sustained clinical gains; and (b) to evaluate a new and more cost-effective child-focused cognitive-behavioural intervention. Unfortunately, the return rate of the questionnaires was poor, rendering this data source of questionable value. However, diagnostic interviews (traditionally the gold standard in terms of outcome in this research area) were completed for all children at all follow-up points. Changes in diagnostic status indicated that meaningful treatment-related gains had been achieved and were maintained over the full follow-up period. The results would thus seem to support the principle of participant-intervention matching proposed by Cobham et al. (1998), as well as the utility of the more brief intervention evaluated.

Immunotherapy strategies aimed at increasing human Valpha24(+)Vbeta11(+) natural killer T (NKT) cell numbers are currently a major focus. To provide further information towards the goal of NKT cell-based immunotherapy, we assessed the effects of age, cancer status and prior anticancer treatment on NKT cell numbers and their expansion capacity following alpha-galactosylceramide (alpha-GalCer) stimulation. The percentage and absolute number of peripheral blood NKT cells was assessed in 40 healthy donors and 109 solid cancer patients ( colorectal ( n = 33), breast ( n = 10), melanoma ( n = 17), lung ( n = 8), renal cell carcinoma ( n = 10), other cancers ( n = 31)). Responsiveness to alpha-GalCer stimulation was also assessed in 28 of the cancer patients and 37 of the healthy donors. Natural killer T cell numbers were significantly reduced in melanoma and breast cancer patients. While NKT numbers decreased with age in healthy donors, NKT cells were decreased in these cancer subgroups despite age and sex adjustments. Prior radiation treatment was shown to contribute to the observed reduction in melanoma patients. Although cancer patient NKT cells were significantly less responsive to alpha-GalCer stimulation, they remained capable of substantial expansion. Natural killer T cells are therefore modulated by age, malignancy and prior anticancer treatment; however, cancer patient NKT cells remain capable of responding to alpha-GalCer-based immenotherapies.

Perceived dissimilarity and its association with work group involvement were examined in this study. Additionally, perceived group openness to diversity was examined as a moderator of this relationship. A longitudinal study was conducted with nurses in four departments of a public hospital. Results revealed that visible dissimilarity was negatively associated with work group involvement at both times, and informational dissimilarity was negatively associated with work group involvement at Time 1. Openness to diversity interacted with visible and informational dissimilarity in the prediction of work group involvement at both times. This interaction pattern showed that there was a negative relationship between dissimilarity and work group involvement when individuals perceived low group openness to diversity, whereas there was no relationship when individuals perceived high group openness to diversity. Results highlight the importance of managing perceptions of difference and introducing norms that encourage the active involvement of group members.

The growth performance and endocrine responses of male weaner pigs (3 to 8 weeks of age) was evaluated in two different environments (clean and dirty) and housing (single or groups of 10 pigs/pen) conditions. The dirty environment contained significantly elevated ammonia, carbon dioxide and dust levels compared with the clean environment. Pigs grew faster and consumed more feed in the clean environment and this was associated with reduced plasma cortisol concentrations compared with pigs in the dirty environment. Pigs housed in groups in the dirty environment had increased β-endorphin and decreased IGF-I concentrations compared to group housed pigs in the clean environment. Feed conversion efficiency did not differ due to environment or group housing. Plasma concentration of cortisol, p-endorphin, IGF-I and IGF-II did not differ between single and group housed pigs. Activity of the hypothalamic-pituitary-adrenal (HPA) axis was greater in response to environmental conditions than group housing, and this was associated with reduced growth in weaner pigs. © 2004 Elsevier B.V.
