Contemporary Review of Group-Oriented Contingencies for Disruptive Behavior

Abstract: This review clarifies the vaguely defined and perplexing terminology that historically has been used in the descriptions of group contingencies. Group contingencies are reviewed and categorized as independent, interdependent, and dependent based on the seminal work of Litow and Pumroy. Further, group contingencies, based on these categorizations, are discussed in terms of their effectiveness and advantages over behavioral interventions designed for individual students.

Risk factors associated with post–kidney transplant malignancies: an article from the Cancer-Kidney International Network

Abstract: In kidney transplant recipients, cancer is one of the leading causes of death with a functioning graft beyond the first year of kidney transplantation, and malignancies account for 8-10% of all deaths in the USA (2.6 deaths/1000 patient-years) and exceed 30% of deaths in Australia (5/1000 patient-years) in kidney transplant recipients. Patient-, transplant- and medication-related factors contribute to the increased cancer risk following kidney transplantation. While it is well established that the overall immunosuppressive dose is associated with an increased risk for cancer following transplantation, the contributive effect of different immunosuppressive agents is not well established. In this review we will discuss the different risk factors for malignancies after kidney transplantation.

Interdependent group contingency and mystery motivators to reduce preschool disruptive behavior

Abstract: Children exhibiting challenging and disruptive behaviors can require teachers to spend a substantial amount of time on classroom management. Disruptive behaviors in the classroom impact the learning process by taking time away from academic instruction. Further, preschoolers who are disruptive are more likely to continue displaying problematic behaviors throughout the remaining school years. Relative to other age groups, there is a paucity of interventions for preschool children with disruptive behavior. Additionally, children from lower economic backgrounds are at a greater risk for both learning and behavioral problems, as characterized by the preschoolers enrolled in Head Start. Group contingencies are practical, efficient, and teacher-friendly behavioral interventions that have been employed with older age groups to reduce disruptive behavior. An ABAB reversal design across 9 preschoolers enrolled in a Head Start classroom was employed to assess the effects of an interdependent group contingency with mystery motivators to reduce disruptive classroom behaviors. The present investigation revealed remarkable reductions of disruptive behavior across all 9 participants. © 2007 Wiley Periodicals, Inc. Psychol Schs 44: 53–63, 2007.

Prognostic significance of miR-205 in endometrial cancer.

Abstract: Purpose microRNAs have emerged as key regulators of gene expression, and their altered expression has been associated with tumorigenesis and tumor progression. Thus, microRNAs have potential as both cancer biomarkers and/or potential novel therapeutic targets. Although accumulating evidence suggests the role of aberrant microRNA expression in endometrial carcinogenesis, there are still limited data available about the prognostic significance of microRNAs in endometrial cancer. The goal of this study is to investigate the prognostic value of selected key microRNAs in endometrial cancer by the analysis of archival formalin-fixed paraffin-embedded tissues.

Lamina Cribrosa Depth in Different Stages of Glaucoma

Abstract: PURPOSE To compare lamina cribrosa (LC) depth between normal eyes and eyes with different stages of treated glaucoma. METHODS Serial enhanced depth imaging (EDI) optical coherence tomography (OCT) B-scans of the optic nerve head were obtained. To generate the mean LC depth for each eye, LC depths were measured in 11 equally spaced horizontal B-scans and averaged. The mean LC depth was compared among normal, preperimetric, mild-to-moderate, and severe glaucoma groups. Among patients with visual field (VF) loss, correlation analysis was performed (1) between mean LC depth and VF mean deviation (MD), and (2) between mean LC depth and retinal nerve fiber layer (RNFL) thickness. RESULTS Eighty-six normal eyes (age, 56 ± 14 years), 47 preperimetric glaucoma eyes (age, 60 ± 16 years), 55 mild-to-moderate glaucoma eyes (age, 59 ± 16 years; VF MD, -6.0 ± 3.2 dB), and 60 severe glaucoma eyes (age, 59 ± 17 years; VF MD, -19.7 ± 6.1 dB) were included. Mean LC depth was significantly greater in preperimetric glaucoma than in normal eyes (390 vs. 344 μm, P = 0.004) and in mild-to-moderate than in preperimetric glaucoma eyes (448 vs. 390 μm, P = 0.001). However, no significant difference was observed between mild-to-moderate and severe glaucoma eyes (448 vs. 437 μm, P = 0.52). No correlation was observed between LC depth and VF MD (P = 0.56) or RNFL thickness (P = 0.90) in glaucomatous eyes with VF loss. CONCLUSIONS In treated glaucoma, posterior LC displacement occurs mostly in the preperimetric and mild-to-moderate glaucoma stages. This warrants further investigation of LC depth as a parameter to monitor glaucoma progression in the early stages.
