Treatment utility of the sociotropy/autonomy distinction: implications for cognitive therapy

The treatment utility of the Sociotropy/Autonomy Scale was evaluated by matching or mismatching subjects to either individual or group cognitive therapy according to their dominant personality dimension. Both groups of subjects obtained statistically significant, but equivalent, reductions in depression. Consistent with Beck's (1983) interactional model, tests of clinical significance indicated a higher proportion of matched subjects who displayed marked improvement at follow-up. Implications for cognitive therapy and further research on the assessment of personality dimensions relevant to depression are discussed.     

Conversations in ethics: exploring the literature

Because of changes in the healthcare industry, many questions have surfaced concerning ethical dilemmas. We, on the ethics committee, thought it a good idea to publish some updated and informative literature concerning these dilemmas.     

Multiple perceptions of discharge planning in one urban hospital

Since the advent of diagnosis-related groups (DRGs), advocacy groups have claimed that although hospital discharge planners perceive the discharge planning process as helpful, elderly patients and their families do not. This article explores how the discharge planning process was perceived by 40 discharge planners and 40 family caregivers. Planners greatly overrated caregiver influence and the amount adequacy of information shared about posthospital health care, choice of discharge to home or nursing home, and time to decide. Caregivers perceived that nursing homes were forced on patients by social workers and physicians. DRGs, physicians, and hospital administrators appeared to pressure social workers to coerce mentally competent patients into nursing homes. Excessive concern by hospital staff about patient safety after discharge may override patients' rights to autonomy and self-determination, violating the NASW Code of Ethics. Implications for practice, policy, and future research are discussed.     

Dissolution of calcified gallstones. Part I. Correlation of in vitro dissolution kinetics in methyl tert-butyl ether with patterns of calcification by computed tomography

RATIONALE AND OBJECTIVES: The authors evaluated the relationship between stone computed tomography (CT) attenuation patterns and the kinetics of dissolution with methyl tertbutyl ether (MTBE). METHODS: Single moderately and heavily calcified gallstones from 40 patients were selected from a gallstone library and classified for pattern of calcification by in vitro CT scan (dense, rim, core, and laminated). Each stone was placed in a 10-mL aliquot of MTBE for 24 hours. Stone residue was blotted dry and weighted at 8, 16, and 24 hours. Results were normalized with respect to stone size. RESULTS: Only 1 of 40 (4%) specimens dissolved to particulate matter that was smaller than 2 mm. All (6 of 6) stones that were densely calcified showed virtually no dissolution. The rate of gallstone dissolution varied temporally within the rim, core, and laminated stone categories and was related to the composition of the layer exposed to the solvent at any given time. CONCLUSION: The success and rate of dissolution may be predicted by the pattern of calcification as determined by computed tomography (CT).     

Visualization of DNA segments, interacting with reactive oligonucleotide derivatives in interphase nuclei and metaphase chromosomes

Reaction of (pdT)16 derivatives, bearing 4-(N-2-chloroethyl-N-methylamino)benzylphosphamide group on its 5' end and biotin on its 3' end with DNA in interphase nuclei and metaphase chromosomes has been investigated by fluorescence and electron microscopy. The result obtained evidence that in interphase nuclei DNA in active chromatin (nucleolus) is the most available for specific modification. In metaphase chromosomes the modified DNA regions are situated on the surface of chromosome.     

Age-dependent modifications in the metabolism of mevalonate pathway lipids in rat brain

Increased public and professional awareness has resulted in more women obtaining mammograms. As a result, the surgeon is often called on to diagnose and treat occult breast lesions. The development of new diagnostic modalities has changed the way such breast lesions are approached. Management decisions are made in the context of new pressures applied by the growing managed care imperative and increased mediocolegal exposure. In this review, we establish guidelines for the management of non-palpable breast abnormalities that place the welfare of the patient first.     

A Russian adaptation of the Child Behavior Checklist: psychometric properties and associations with child and maternal affective symptomatology and family function

The Child Behavior Checklist's (CBCL) applicability to a sample of 105 Russian 9- and 10-year-old children was evaluated by examining the internal consistency of Russian adaptations of parent and teacher report forms. In addition, child behavior scores were correlated with child report of internalizing symptoms and maternal reports of their own internalizing symptoms and general family functioning. Finally, rates of child behavior problems and patterns of interrater agreement were compared with U.S. normative data. The psychometric properties of the adaptations demonstrate the adequacy of these instruments for use in Russia. Internal consistency and interrater agreement were generally comparable to estimates obtained in U.S. normative samples. Further, an exploration of the construct validity of the Russian versions of the CBCL and Teacher Report Form (TRF) lends additional support to the adequacy of these instrument.     

Characterization of a 50-kDa polypeptide in cytoplasmic dynein preparations reveals a complex with p150GLUED and a novel actin

Earlier work identified a series of accessory polypeptides of 150, 74, 59, 57, 55, 53, 50, and 45 kDa copurifying with cytoplasmic dynein. In the present study immunoprecipitation of the 50-kDa polypeptide from bovine brain cytosol with a specific monoclonal antibody revealed coprecipitating components of 150, 135, 62, and 45 kDa, which were completely distinct from the polypeptides immunoprecipitated using an antibody to the well established 74-kDa cytoplasmic dynein subunit. The 150- and 135-kDa polypeptides reacted with an antibody to p150Glued, the mammalian homologue of the Drosophila Glued gene. N-terminal microsequencing of tryptic peptides of the major 45-kDa component of the complex revealed it to be the alpha-isoform of centractin, a novel form of actin. Immunoblotting of sucrose gradient-fractionated brain cytosol revealed p150Glued, p50, and centractin to cosediment exclusively at 20 S. Immunofluorescence microscopy using antibody to p150Glued revealed centrosomal staining, which was abolished by microtubule depolymerization. Together these results reveal the 50-kDa polypeptide to be part of a cytosolic complex distinct from cytoplasmic dynein. However, the immunolocalization data indicate an association with microtubule minus ends, suggesting a possible interaction with cytoplasmic dynein in the cell.
