Proteomic-based discovery and characterization of glycosylated eosinophil-derived neurotoxin and COOH-terminal osteopontin fragments for ovarian cancer in urine.

PURPOSE: The objective was to identify and characterize low molecular weight proteins/peptides in urine and their posttranslational modifications that might be used as a screening tool for ovarian cancer. EXPERIMENTAL DESIGN: Urine samples collected preoperatively from postmenopausal women with ovarian cancer and benign conditions and from nonsurgical controls were analyzed by surface-enhanced laser desorption/ionization mass spectrometry and two-dimensional gel electrophoresis. Selected proteins from mass profiles were purified by chromatography and followed by liquid chromatography-tandem mass spectrometry sequence analysis. Specific antibodies were generated for further characterization, including immunoprecipitation and glycosylation. Quantitative and semiquantitative ELISAs were developed for preliminary validation in patients of 128 ovarian cancer, 52 benign conditions, 44 other cancers, and 188 healthy controls. RESULTS: A protein (m/z approximately 17,400) with higher peak intensities in cancer patients than in benign conditions and controls was identified and subsequently defined as eosinophil-derived neurotoxin (EDN). A glycosylated form of EDN was specifically elevated in ovarian cancer patients. A cluster of COOH-terminal osteopontin was identified from two-dimensional gels of urine from cancer patients. Modified forms EDN and osteopontin fragments were elevated in early-stage ovarian cancers and a combination of both resulted to 93% specificity and 72% sensitivity. CONCLUSIONS: Specific elevated posttranslationally modified urinary EDN and osteopontin COOH-terminal fragments in ovarian cancer might lead to potential noninvasive screening tests for early diagnosis. Urine with less complexity than serum and relatively high thermodynamic stability of peptides or metabolites is a promising study medium for discovery of the novel biomarkers which may present in many non-urinary tract neoplastic diseases.     

The wreathing protocol: the imbrication of hypnosis and EMDR in the treatment of dissociative identity disorder and other dissociative responses. Eye Movement Desensitization Reprocessing

Dissociative Identity Disorder (DID), a chronic childhood onset posttraumatic stress disorder, is currently recognized as a treatable condition. It is considered the paradigmatic dissociative condition and carries with it extreme posttraumatic symptomatology. Therapists skilled in the treatment of DID are typically fluent in the uses of hypnosis for stabilization, affect management, building a safe place and grounding to name of few. EMDR, which has come to the forefront of clinical awareness in the last ten years, seems aptly suited for the treatment of trauma, but can be destabilizing. This paper proposes a protocol, called Wreathing Protocol, for the imbricated use of EMDR and hypnosis in the treatment of not only DID (though this will be the primary focus of the paper), but also Dissociative Disorder Not Otherwise Specified (DDNOS) and chronic Posttraumatic Stress Disorder (PTSD). This protocol is useful to advanced clinicians skilled in both modalities independently. The sequential steps of the Wreathing Protocol will be described and illustrated by a clinical vignette on DID. The clinical implications of the use of the Wreathing Protocol will be discussed in DID as well as the chronic post traumatic spectrum.     

Standards for total body fat and fat-free mass in infants

Data on body composition in conjunction with reference centiles are helpful in identifying the severity of growth and nutritional disorders in infancy and for evaluating the adequacy of treatment given during this important period of rapid growth. Total body fat (TBF) and fat-free mass (FFM) were estimated from total body electrical conductivity (TBEC) measurements in 423 healthy term Caucasian infants, aged 14-379 days. Cross sectional age, weight, and length related centile standards are presented for TBF and FFM. Centiles were calculated using Altman's method, based on polynomial regression and modelling of the residual variation. The TBF percentage steeply increased during the first half year of life, and slowly declined beyond this age. Various simple TBEC derived anthropometric prediction equations for TBF and FFM are available to be used in conjunction with these standards. Regression equations for the P50 and the residual SD, depending on age, weight, or length, are provided for constructing centile charts and calculating standard deviation scores.     

The Community Tool Box: a Web-based resource for building healthier communities

Building healthier cities and communities requires an array of community-building skills that are not always taught in formal education. The Community Tool Box (http://ctb.ukans.edu) is an Internet-based resource for practical, comprehensive, accessible, and user-friendly information on community-building, which both professionals and ordinary citizens can use in everyday practice. It connects people, ideas, and resources, offering more than 200 how-to sections and more than 5,000 pages of text.     

Phase II study of etoposide (VP-16) in patients with thyroid cancer with no prior chemotherapy: an Eastern Cooperative Oncology Group Study (E1385)

This study of etoposide in thyroid cancer was designed to determine the activity and toxicity of etoposide in a variety of inoperable, thyroid hormone insensitive, and radio-iodine resistant primary cancers of the thyroid. The patients were required to have an ECOG performance status of at least 3 and no previous exposure to chemotherapy. The etoposide was given at a dose of 140 mg/m² daily for 3 days and every 3 weeks until progression. The study was closed after 18 months because of poor accrual. There were no responses seen among the 10 patients accrued. The toxicity was primarily hematologic. There was no evidence of activity of etoposide in thyroid carcinoma, although this study lacked significant power because of the poor accrual.
