BACKGROUND: The utility of chemotherapy for women who experience a locoregional recurrence after primary treatment of early breast cancer remains an open question. An international collaborative trial is being conducted by the Breast International Group (BIG), the International Breast Cancer Study Group (IBCSG), and the National Surgical Adjuvant Breast and Bowel Project (NSABP) to determine the effectiveness of cytotoxic therapy for these patients, either alone or in addition to selective use of hormonal therapy and trastuzumab. METHODS: The trial population includes women who have had a previous diagnosis of invasive breast cancer treated by mastectomy or breast-conserving surgery, but subsequently develop an isolated local and/or regional ipsilateral invasive recurrence. Excision of all macroscopic tumor without evidence of systemic disease is required for study entry. Patients are randomized to receive chemotherapy or no chemotherapy; type of chemotherapy is not protocol-specified. Radiation, hormonal therapy, and trastuzumab are given as appropriate. The primary endpoint is disease-free survival (DFS). Quality-of-life measurements are collected at baseline, and then at 9 and 12 months. The accrual goal is 977 patients. RESULTS: This report describes the characteristics of the first 99 patients. Sites of recurrence at study entry were: breast (56%), mastectomy scar/chest wall (35%), and regional lymph nodes (9%). Two-thirds of patients have estrogen-receptor-positive recurrences. CONCLUSION: This is the only trial actively investigating the question of "adjuvant" chemotherapy in locally recurrent breast cancer. The case mix of accrual to date indicates a broad representation of this patient population.

OBJECTIVE: To develop a novel application of a tool for semi-automatic volume segmentation and adapt it for analysis of fetal cardiac cavities and vessels from heart volume datasets. METHODS: We studied retrospectively virtual cardiac volume cycles obtained with spatiotemporal image correlation (STIC) from six fetuses with postnatally confirmed diagnoses: four with normal hearts between 19 and 29 completed gestational weeks, one with d-transposition of the great arteries and one with hypoplastic left heart syndrome. The volumes were analyzed offline using a commercially available segmentation algorithm designed for ovarian folliculometry. Using this software, individual 'cavities' in a static volume are selected and assigned individual colors in cross-sections and in 3D-rendered views, and their dimensions (diameters and volumes) can be calculated. RESULTS: Individual segments of fetal cardiac cavities could be separated, adjacent segments merged and the resulting electronic casts studied in their spatial context. Volume measurements could also be performed. Exemplary images and interactive videoclips showing the segmented digital casts were generated. CONCLUSION: The approach presented here is an important step towards an automated fetal volume echocardiogram. It has the potential both to help in obtaining a correct structural diagnosis, and to generate exemplary visual displays of cardiac anatomy in normal and structurally abnormal cases for consultation and teaching.

The fields of Rhetoric and Communication usually assume a competent speaker who is able to speak well with conscious intent; however, what happens when intent and comprehension are intact but communicative facilities are impaired (e.g., by stroke or traumatic brain injury)? What might a focus on communicative success be able to tell us in those instances? This project considers this question in examining communication disorders through identifying and analyzing patterns of (dis) fluent speech between 10 aphasic and 10 non-aphasic adults. The analysis in this report is centered on a collection of data provided by the Aphasia Bank database. The database’s collection protocol guides aphasic and non-aphasic participants through a series of language assessments, and for my re-analysis of the database’s transcripts I consider communicative success is and how it is demonstrated during a re-telling of the Cinderella narrative. I conducted a thorough examination of a set of participant transcripts to understand the contexts in which speech errors occur, and how (dis) fluencies may follow from aphasic and non-aphasic participant’s speech patterns. An inductive mixed-methods approach, informed by grounded theory, qualitative, and linguistic analyses of the transcripts functioned as a means to balance the classification of data, providing a foundation for all sampling decisions. A close examination of the transcripts and the codes of the Aphasia Bank database suggest that while the coding is abundant and detailed, that further levels of coding and analysis may be needed to reveal underlying similarities and differences in aphasic vs. non-aphasic linguistic behavior. Through four successive levels of increasingly detailed analysis, I found that patterns of repair by aphasics and non-aphasics differed primarily in degree rather than kind. This finding may have therapeutic impact, in reassuring aphasics that they are on the right track to achieving communicative fluency.

Background: Medical students do not accurately self-assess their competence. However, little is known about the awareness of change of competence over time. The aim of this study was to evaluate if students are aware of their progress. Summary of work: Twenty-two fourth year medical students had self- and expert-assessments of their clinical skills in musculoskeletal medicine in an OSCE like station (4 point Likert scale) at the beginning (t0) and end (t1) of their eight weeks clerkship in internal medicine. Thirteen students were assigned to the intervention of a 6x1 hour practical examination course; nine took part in the regular clinical clerkship activities only and served as controls. Summary of results/Conclusions: The intervention students significantly improved their skills (from 2.78 ± 0.36 to 3.30 ± 0.36, p<0.05) in contrast to the control students (from 3.11 ± 0.58 to 2.83 ± 0.49, n.s.). At t0, 19 students, at t1 21 out of 22 students underestimated their competence. Correlations between the change of self- and expert-assessment were r=0.43, p<0.05 (all), r=0.47, n.s. (control) and r=-0.12, n.s. (intervention), respectively. Take-home message: Medical students improving their clinical skills by an interactive course in addition to their regular clerkship activities are not aware of their progress

Social work has had varying relationships with the nation state both over time and between different countries. From its early stages the occupation had both state sanctioned and voluntary streams. Its international dimension has been enhanced in the European context through policy and funding measures over the past few decades. During this period we have also seen the rise of globalising trends leading to questions about the ongoing powers of nation states. This paper examines some aspects of the relationship between social work and the state, taking into account the emergence of European and also international policies and frameworks. The paper focuses initially on migration as an example of a common trend; an area of policy with both national and European dimensions; and a field in which social professionals are engaged to varying degrees. Secondly, it considers the progress of the ‘professional project’ in Europe, using developments in five countries to illustrate some of the issues associated with ‘professionalization’. European and international frameworks may lead to some convergence in national understandings of the key roles of social workers and an enhanced sense of professional identity across nation states, despite very different starting points and current forms of organisation.

In developed countries, the transition from school to work has radically changed over the past two decades. It has become prolonged, complicated and individualized (Bynner et al., 1997; Walther et al., 2004). Young people used to transition directly from school to stable employment, or with a very short unemployed period. In many European countries, this situation has been changing since the eighties: overall youth unemployment has increased, and many young people experience long periods of unemployment, government training schemes and part-time or temporary jobs. In Japan, this change has taken a decade later to appear, becoming prevalent by the late nineties (Inui, 2003). The transiting process has become not only precarious for young people, but also difficult for society to precisely understand the risks and problems. Traditionally, we have been able to recognize young people's situation by a simple category: in education, employed, in training or unemployed. However, these categories no longer accurately represent young people's state. In Japan, most young people used to move from school directly to full-time employment through the new graduate recruitment system (Inui, 1993). Therefore, in official statistics such as the School Basic Survey, 'employed' includes only those who are in regular employment, while those who are in part-time or temporary work are covered by the categories 'jobless' and 'others'. However, with the increase in non-full-time jobs in the nineties, these categories have become less useful for describing the actual employment conditions of young people. Indeed, this is why, in the late of nineties, the Japanese Ministry of Education changed the category name from 'jobless' to 'others'.

Since the nineteenth century invention of adolescence, young people have been consistently identified as social problems in western societies. Their contemporary status as a focus of fear and anxiety is, in that sense, nothing new. In this paper, I try to combine this sense of historical recurrence about the youth problem with some questions about what is different about the present – asking what is distinctive about the shape of the youth problem now? This is a difficult balance to strike, and what I have to say will probably lean more towards an emphasis on the historical conditions and routes of the youth problem. That balance reflects my own orientations and knowledge (I am not expert on the contemporary conditions of being young). But it also arises from my belief that much contemporary social science is profoundly forgetful. An enthusiasm for stressing the newness, or novelty, of the present connects many varieties of contemporary scholarship. One result is the construction of what Janet Fink and I have referred to as ‘sociological time’ in which
