    The relationship between socially oriented client characteristics and facilitative therapist variables on client perceptions of the therapeutic relationship (CPTR) was investigated. Subjects were75 undergraduate students who answered a pretherapy questionnaire to measure the socially oriented client variables trusting, warmth, dominance (16PF), sex role orientation (Bem Sex Role Inventory), wanted and expressed inclusion, control, and affection (FIRO-B). Subjects were blocked on trusting and expressed affection and randomly assigned to a warm or neutral therapist condition where they saw a counselor for one fifty minute session. CPTR was measured using the Barrett-Lennard Relationship Inventory, Counselor Rating Form, Therapist Rating Scales and Global Warmth Rating. Results indicated that subjects perceived a difference in the warm and neutral therapist conditions. And there was a significant interaction between the client variables of trusting and therapist condition. In addition, a significant interaction between the client variables of trusting and expressed affection was found. Additional correlational analysis indicated that certain other client variables are also related to CPTR

    Heterogeneity in early language development in autism spectrum disorder (ASD) is clinically important and may reflect neurobiologically distinct subtypes. Here, we identified a large-scale association between multiple coordinated blood leukocyte gene coexpression modules and the multivariate functional neuroimaging (fMRI) response to speech. Gene coexpression modules associated with the multivariate fMRI response to speech were different for all pairwise comparisons between typically developing toddlers and toddlers with ASD and poor versus good early language outcome. Associated coexpression modules were enriched in genes that are broadly expressed in the brain and many other tissues. These coexpression modules were also enriched in ASD-associated, prenatal, human-specific, and language-relevant genes. This work highlights distinctive neurobiology in ASD subtypes with different early language outcomes that is present well before such outcomes are known. Associations between neuroimaging measures and gene expression levels in blood leukocytes may offer a unique in vivo window into identifying brain-relevant molecular mechanisms in ASD

    Costlets: A Generalized Approach to Cost Functions for Automated Optimization of IMRT Treatment Plans

    We present the creation and use of a generalized cost function methodology based on costlets for automated optimization for conformal and intensity modulated radiotherapy treatment plans. In our approach, cost functions are created by combining clinically relevant “costlets”. Each costlet is created by the user, using an “evaluator” of the plan or dose distribution which is incorporated into a function or “modifier” to create an individual costlet. Dose statistics, dose-volume points, biological model results, non-dosimetric parameters, and any other information can be converted into a costlet. A wide variety of different types of costlets can be used concurrently. Individual costlet changes affect not only the results for that structure, but also all the other structures in the plan (e.g., a change in a normal tissue costlet can have large effects on target volume results as well as the normal tissue). Effective cost functions can be created from combinations of dose-based costlets, dose-volume costlets, biological model costlets, and other parameters. Generalized cost functions based on costlets have been demonstrated, and show potential for allowing input of numerous clinical issues into the optimization process, thereby helping to achieve clinically useful optimized plans. In this paper, we describe and illustrate the use of the costlets in an automated planning system developed and used clinically at the University of Michigan Medical Center. We place particular emphasis on the flexibility of the system, and its ability to discover a variety of plans making various trade-offs between clinical goals of the treatment that may be difficult to meet simultaneously.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47484/1/11081_2005_Article_2066.pd

    A precise extragalactic test of General Relativity

    Einstein’s theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby strong gravitational lens ESO 325-G004 provides a laboratory to probe the weak-field regime of gravity and measure the spatial curvature generated per unit mass, Îł. By reconstructing the observed light profile of the lensed arcs and the observed spatially resolved stellar kinematics with a single self-consistent model, we conclude that Îł = 0.97 ± 0.09 at 68% confidence. Our result is consistent with the prediction of 1 from General Relativity and provides a strong extragalactic constraint on the weak-field metric of gravity

    Prospective Multicenter Study of Surgical Correction of Pectus Excavatum: Design, Perioperative Complications, Pain, and Baseline Pulmonary Function Facilitated by Internet-Based Data Collection

    Background: Given widespread adoption of the Nuss procedure, prospective multicenter study of management of pectus excavatum by both the open and Nuss procedures was thought desirable. Although surgical repair has been performed for more than 50 years, there are no prospective multicenter studies of its management. Study Design: This observational study followed pectus excavatum patients treated surgically at 11 centers in North America, according to the method of choice of the patient and surgeon. Before operation, all underwent evaluation with CT scan, pulmonary function tests, and body image survey. Data were collected about associated conditions, hospital complications, and perioperative pain. One year after completion of treatment, patients will repeat the preoperative evaluations. This article addresses early results only. Results: Of 416 patients screened, 327 were enrolled; 284 underwent the Nuss procedure and 43 had the open procedure. Median preoperative CT index was 4.4. Pulmonary function testing before operation showed mean forced vital capacity of 90% of predicted values; forced expiratory volume in 1 second (FEV1), 89% of predicted; and forced expiratory flow during the middle half of the forced vital capacity (FEF25% to 75%), 85% of predicted. Early postcorrection results showed that operations were performed without mortality and with minimal morbidity at 30 days postoperatively. Median hospital stay was 4 days. Postoperative pain was a median of 3 on a scale of 10 at time of discharge; the worst pain experienced was the same as was expected by the patients (median 8), and by 30 days after correction or operation, the median pain score was 1. Because of disproportionate enrollment and similar early complication rates, statistical comparison between operation types was limited. Conclusions: Anatomically severe pectus excavatum is associated with abnormal pulmonary function. Initial operative correction performed at a variety of centers can be completed safely. Perioperative pain is successfully managed by current techniques
