Objective: Our aim was to examine the reliability and validity of the Rupture Resolution Rating System (3RS), an observer-based measure of alliance ruptures and resolution processes. Method: We used the 3RS to rate early sessions from 42 cases of cognitive behavior therapy. We compared the 3RS to a simplified version of the Structural Analysis of Social Behavior (SASB), as well as patient and therapist self-reports of ruptures and the alliance. Results: Coders achieved high rates of interrater reliability on the frequency of confrontation and withdrawal ruptures and resolution strategies (ICCs?=?.85 to .98), as well as ratings of the therapist’s contribution to ruptures and the extent to which ruptures were resolved (ICC?=?.92). Predictive validity analyses found that confrontation markers (d?=?.74), successful resolution (d?=?.67), and ratings of the therapist’s contribution to ruptures (d?=?.61) predicted dropout from therapy. Analyses of convergent validity with the SASB failed to meet predictions; however, we observed theoretically coherent relations between 3RS and SASB variables. Confrontation rupture markers were significantly associated with patient self-report of rupture (d?=?1.54) and therapist self-reported alliance (r?=??.50, p?=?.002). Conclusions: This study provides evidence that the 3RS is a reliable and useful tool for examining psychotherapy process and predicting dropout.
Clinical or methodological significance of this article: This study provides evidence of the reliability and validity of the 3RS, an observer-based measure of alliance ruptures and resolution processes. The 3RS can be used to identify problems in the therapeutic relationship that are associated with premature dropout from therapy. 相似文献

Introduction
Dental pulp stem cells (DPSCs) have therapeutic potential for dentin and dental pulp regeneration. For regenerative approaches to gain clinical acceptance, protocols are needed to determine feasible ways to store teeth, isolate DPSCs, and expand them to clinical scale numbers.Methods
In this study, 32 third molars were obtained from patients and immediately placed in saline or tissue culture medium followed by overnight storage at 4°C or immediate isolation of DPSCs. Upon isolation, cells were expanded in medium containing either fetal bovine serum (FBS) or human serum (HS). Cell proliferation (population doubling time [PDT]), cell surface marker expression, and multipotency were compared between DPSCs in FBS and DPSCs in HS.Results
The time frame of storage and storage medium did not affect the ability to isolate DPSCs. However, using HS instead of FBS in the initial isolation of DPSCs significantly decreased (P < .01) the isolation success rate from 89% (FBS) to 23% (HS). Yet, incorporating fibronectin in the DPSC initial isolation (using HS) significantly (P < .01) increased the isolation success rate to 83%. Interestingly, it was found that the proliferation rate was significantly (P < .05) higher for DPSCs in HS (PDT = 1.59 ± 0.46) than that for DPSCs in FBS (PDT = 2.84 ± 2.5). Finally, there was no difference in the expression of CD73, CD90, CD105, or multipotency (as measured by osteogenic, adipogenic, and chondrogenic differentiation) between DPSCs in FBS and DPSCs in HS.Conclusions
These findings show a clinically feasible method of storing third molars for the isolation of DPSCs. Additionally, DPSCs can be isolated and expanded to clinical scale numbers in media devoid of FBS and still maintain their phenotypic properties. 相似文献3.

Previous studies have established that a complex behavioral syndrome--consisting of tremor, rigidity, hindlimb abduction. Straub tail, lateral head weaving and reciprocal forepaw treading--is a specific reflection of the activity of central serotonin receptors. This syndrome was utilized in the present study to test for supersensitivity in the central serotonergic system. Specific destruction of central serotonin nerve terminals by intraventricular injection of 5,7-dihydroxytryptamine (5,7-DHT, 50 mug) in adult male rats pretreated with a catecholamine uptake blocking agent resulted in marked supersensitivity to serotonin precursors and agonists. The greatest degree of supersensitivity was observed in response to L-5-hydroxytryptophan, for which the ED50 for elicitation of the syndrome was 20% of the value for control rats. A lesser degree of supersensitivity was seen in response to L-tryptophan (following monoamine oxidase inhibition) and the direct-acting serotonin agonist, 5-methoxy-N,N-dimethyltryptamine, for which the ED50 was approximately 50% of the control value in both cases. Supersensitivity begins to develop within 24 hours and is relatively complete by 96 hours after 5,7-DHT. A marked subsensitivity to the serotonin releasing agent, fenfluramine, was found in 5,7-DHT-treated rats. In contrast to the marked supersensitivity to serotonin precursors and agonists which occurs following 5,7-DHT, chronic administration of a serotonin synthesis inhibitor, p-chlorophenylalanine (400 mg/kg every 3 days for a total of 24 days), did not produce supersensitivity to L-5-hydroxytryptophan or 5-methoxy-N,N-dimethyltryptamine. Possible pre- and postsynaptic mechanisms for the development of supersensitivity are discussed. 相似文献

Common hepatic duct obstruction secondary to an impacted cystic duct stone is commonly referred to as the Mirizzi syndrome. Mirizzi syndrome is an uncommon cause of obstructive jaundice and can be mimicked by several other rare conditions. We describe a patient with a massively distended gallbladder due to acute cholecystitis who presented with clinical and cholangiographic findings simulating the Mirizzi syndrome. Endoscopists should be aware of acute cholecystitis as a possible etiology of common hepatic duct obstruction. 相似文献

An unconscious victim of an overdose was intubated with an endotracheal tube to prevent aspiration. The respiratory therapist deflated the cuff of the endotracheal tube to allow for a retrograde oral air leak and then tightly attached the oxygen tube directly to the endotracheal tube. Seconds later there was a loud pop as the oxygen tube blew off the end of the endotracheal tube. The patient sustained both a hemodynamic and a neurologic decompensation as the result of marked pulmonary overinflation, with bilateral pneumothoraces and probable cerebral and coronary artery air emboli. We present the case in the hope that it will help avoid any such future occurrences. 相似文献

Methods for the construction of ordered nanoscale arrays have been implicated in fields ranging from separation technologies to microelectronics. Yet, despite the plethora of nanoscale structures assembled in nature that use a templating strategy, chemists have been unable to replicate this success. A technology is reported for templated organic polymers composed of filamentous bacteriophage-polyacrylamide biomacromolecules that self-assemble into highly ordered helical bundles displaying hexagonal close packing. The results align with a previously reported mathematical prediction for the close packing of flexible tubes. This biopolymeric assembly can be viewed as a magnification of the inherent microscopic chirality and helicity present in individual phage particles at the macroscale level. 相似文献
