Assessment of prostate cancer with integrated CT-perfusion using a sector-wise approach.

OBJECTIVE The role of computed tomography perfusion (CTP) in characterizing primary prostate cancer (PCa) is not definitely known. The aim of the present study was to investigate the relationship between CTP parameters and histopathological features of PCa tissue, using a sector-wise approach. MATERIAL AND METHODS Fifty-one patients with biopsy-proven PCa underwent prospectively a CTP scan prior to radical prostatectomy. Blood flow (BF), mean blood volume (BV) and mean transit time (MTT) were calculated, with the prostate being divided into eight sectors. Corresponding sector-wise histopathological analysis of whole-mount prostatectomy specimens was performed to determine tumoral area (mm2), mean microvessel density (MVD), Gleason patterns (primary, secondary) and total Gleason score. Spearman's rank correlation coefficient was used to analyze the association between CTP and histopathological parameters. RESULTS BF correlated weakly with tumoral area [ρs coefficient (p-value): 0.25 (0.00)] and MVD [ρs coefficient (p-value): 0.23 (0.00)]. No valuable correlation was found between CTP parameters and primary and secondary Gleason patterns, whereas total Gleason score was weakly correlated with BV [ρs coefficient (p-value): 0.22 (0.00)] and MTT [ρs coefficient (p-value): 0.25 (0.00)]. CONCLUSION BF correlates weakly with size and vascularity of PCa. There is a need for further studies to elucidate the association between CTP parameters and other histopathological parameters.
Screening mammography for women in their 40s: a retrospective study of the potential impact of the U.S. Preventive Service Task Force's 2009 breast cancer screening recommendations.

OBJECTIVE The objective of our study was to review screening mammography examinations performed at our institution from 2007 through 2010 with the primary endpoint of determining the incidence of breast cancer and associated histologic and prognostic features in women in their 40s. MATERIALS AND METHODS Patients who presented for screening mammography who ultimately (i.e., after additional imaging, including diagnostic mammographic views and ultrasound) received a BI-RADS assessment of a category 4 or 5 for a suspicious abnormality were followed retrospectively through completion of care and were analyzed with respect to pathology results after biopsy, treatment, and family history. RESULTS During the study period, 43,351 screening mammography examinations were performed; 1227 biopsies were recommended on the basis of those studies and yielded 205 breast cancers (cancer detection rate of 4.7 per 1000 screening examinations). These screening examinations included 14,528 (33.5%) screening examinations of patients in their 40s; 413 biopsies were recommended and yielded 39 breast cancers (39/205 = 19%) (cancer detection rate of 2.7 per 1000 screening examinations). More than 50% (21/39) of the cancers in women in their 40s were invasive. Only 8% (3/39) of the women in their 40s with screening-detected breast cancer had a first-degree relative with breast cancer. CONCLUSION From 2007 through 2010, patients in their 40s accounted for one third of the population undergoing screening mammography and for nearly 20% of the screening-detected breast cancers--more than half of which were invasive. This information should be a useful contribution to counseling women in this age group when discussing whether or not to pursue regular screening mammography.
Sentiment Classification and Polarity Shifting

Polarity shifting marked by various linguistic structures has been a challenge to automatic sentiment classification. In this paper, we propose a machine learning approach to incorporate polarity shifting information into a document-level sentiment classification system. First, a feature selection method is adopted to automatically generate the training data for a binary classifier on polarity shifting detection of sentences. Then, by using the obtained binary classifier, each document in the original polarity classification training data is split into two partitions, polarity-shifted and polarity-unshifted, which are used to train two base classifiers respectively for further classifier combination. The experimental results across four different domains demonstrate the effectiveness of our approach.
Support in the Workplace: Buffering the Deleterious Effects of Work–Family Conflict on Child Welfare Workers’ Well-Being and Job Burnout

ABSTRACT We examined the impact of work–family conflict (WFC) on worker well-being and job burnout, as well as the role of social support in the workplace as a potential buffer against the influence of WFC. Results of hierarchical multiple regression analyses in a cross-sectional sample of 361 public child welfare workers indicate that WFC was related to reduced well-being and increased job burnout, whereas supervisory support moderated the relationship between WFC and well-being. Findings from this study hold implications to workforce management practices aimed at improving worker well-being in human service and child welfare organizations. Human resource management policies designed to manage worker schedules should aim to facilitate workers’ ability to meet work and family demands through programs such as flexible work schedules and telecommuting. Recommendations for future research on WFC and worker well-being are discussed.
Reliability of Heel-Height Measurement for Documenting Knee Extension Deficits *

Background Heel-height difference has been used to detect subtle knee flexion contractures, but the effects of thigh circumference differences and patient positioning during testing have not been evaluated. Hypothesis Differences in thigh circumference measurements and whether the patient's patellae are on or off the examination table during heel-height difference measurement will not affect the accuracy of detecting knee flexion contracture. Study Design Prospective cohort study. Methods Bilateral knee range of motion, prone heel-height difference with the patellae on and off the table, and thigh circumference at 5 and 15 cm proximal to the proximal pole of the patella were measured by one investigator on 50 consecutive patients who had undergone unilateral anterior cruciate ligament reconstruction. Results A high degree of correlation was demonstrated between the heel-height difference and the standard range of motion measurement. Differences in thigh girth and patellar position did not statistically affect the accuracy of the heel-height difference as an indicator of knee flexion contracture. Conclusion Heel-height difference is a valid method of documenting knee flexion contractures. Compared with traditional goniometer assessment, this test is a more meaningful and easier way for detecting subtle knee flexion contractures of less than 10°.
Public Access Defibrillation in Out-of-Hospital Cardiac Arrest: A Community-Based Study

Background—The dissemination and use of automated external defibrillators (AEDs) beyond traditional emergency medical services (EMS) into the community has not been fully evaluated. We evaluated the frequency and outcome of non-EMS AED use in a community experience. Methods and Results—The investigation was a cohort study of out-of-hospital cardiac arrest cases due to underlying heart disease treated by public access defibrillation (PAD) between January 1, 1999, and December 31, 2002, in Seattle and surrounding King County, Washington. Public access defibrillation was defined as out-of-hospital cardiac arrest treated with AED application by persons outside traditional emergency medical services. The EMS of Seattle and King County developed a voluntary Community Responder AED Program and registry of PAD AEDs. During the 4 years, 475 AEDs were placed in a variety of settings, and more than 4000 persons were trained in cardiopulmonary resuscitation and AED operation. A total of 50 cases of out-of-hospital cardiac arrest were treated by PAD before EMS arrival, which represented 1.33% (50/3754) of all EMS-treated cardiac arrests. The proportion treated by PAD AED increased each year, from 0.82% in 1999 to 1.12% in 2000, 1.41% in 2001, and 2.05% in 2002 (P = 0.019, test for trend). Half of the 50 persons treated with PAD survived to hospital discharge, with similar survival for nonmedical settings (45% [14/31]) and out-of-hospital medical settings (58% [11/19]). Conclusions—PAD was involved in only a small but increasing proportion of out-of-hospital cardiac arrests.
Public Values

Exploring boundaries and meanings of public value, the authors seek to identify some of the impediments to progress in the study of public values. The study of public values is often hamstrung by more general problems in the study of values. The authors begin by identifying analytical problems in the study of values and public values. Then they take stock of the public values universe. To identify public value concepts, relevant literature is reviewed and interpreted. Finally, the analytical questions posed in the first section are addressed, focusing specifically on issues related to the hierarchy, causality, and proximity of public values.
Towards the post-ultimate libm

This article presents advances on the subject of correctly rounded elementary functions since the publication of the libultim mathematical library developed by Ziv at IBM. This library showed that the average performance and memory overhead of correct rounding could be made negligible. However, the worst-case overhead was still a factor 1000 or more. It is shown that, with current processor technology, this worst-case overhead can be kept within a factor of 2 to 10 of current best libms. This low overhead has very positive consequences on the techniques for implementing and proving correctly rounded functions, which are also studied. These results lift the last technical obstacles to a generalisation of (at least some) correctly rounded double precision elementary functions.
Evaluation of Support Groups for Child Abuse Prevention: Outcomes of Four State Evaluations

ABSTRACT Parent support groups have grown in popularity as a strategy for preventing child maltreatment, but there have been few evaluations of these groups. The purpose of this paper is twofold. One goal is to identify some of the major challenges in the evaluation of parent support groups and to provide strategies for minimizing these potential difficulties. The second goal is to illustrate successful evaluations of parent support groups (i.e., the Circle of Parents® program) in four states. Three of these states used a retrospective pretest method. Outcomes indicated positive performance across all domains of functioning, as measured by a self-report questionnaire. Strengths and limitations of the evaluations are discussed, and recommendations for future evaluations are provided.
Leader Self-Awareness and Its Relationship to Subordinate Assessment of Organizational Atmosphere in the Social Welfare Sector

ABSTRACT This study examined how supervision-subordinate ratings are related to the estimates of organizational effectiveness in the social welfare sector. The results indicated that the quality of leadership was correlated with the quality of the activity in the work community estimated by the subordinates. Leaders (managers) were divided into three groups (under-estimators, accurate assessors, and over-estimators). Group membership was based on the discrepancy between self-ratings and mean subordinate ratings. The results indicated that accurate and underrating are related to good evaluation of work activities. The results of the study showed that there are connections between the quality of performance of the working community and the actions of superiors, as well as their ability for self-assessment. The superior's self-assessment is a skill, which can be developed, for example, from a practical reflective point of view.
Instituting Science: Discovery or Construction of Scientific Knowledge?

Is knowledge in the natural sciences discovered or constructed? For objectivists, scientific knowledge is discovered through investigations into a mind‐independent, natural world. For constructivists, such knowledge is produced through negotiations among members of a professional guild. I examine the clash between the two positions and propose that scientific knowledge is the concurrent outcome from investigations into a natural world and from consensus reached through negotiations of a professional guild. Specifically, I introduce the general methodological notion, instituting science, which incorporates both the discovery and the construction processes in the generation of scientific knowledge. To that end, I use a case study from the biomedical sciences to illustrate the notion. I conclude with a discussion of how this methodological notion helps to address the debate between objectivists and constructivists over the generation of scientific knowledge, and of how it compares with others who have also attempted to address the debate.
Consumer Ethnocentrism, Attitudes, and Purchase Behavior

Abstract Consumer ethnocentrism (CE) is an important area of study in cross-cultural consumer research. Since the CETSCALE was published (Shimp and Sharma 1987), studies have used the scale in a variety of research contexts. The scale's importance stems, in part, from its predictive properties. Specifically, CETSCALE scores have been shown to affect consumers' beliefs, attitudes, and behavioral intentions toward foreign-made products (Netemeyer, Durvasula, and Lichtenstein 1991; Shimp and Sharma 1987). This paper builds on earlier contributions to propose a CE nomological model. Income, CE, and general product attitudes predict the proportion of locally produced and import products purchased by a sample of Israeli consumers. The findings suggest that the three antecedents, in different combinations, affect purchase behaviors for the products studied.
Preschool children's social and nonsocial play behaviours. Measurement and correlations with children's playfulness, behaviour problems and demographic characteristics

Children's play contributes to their overall development. Yet, not all types of play have the same effects. On the contrary, nonsocial play has been found to be correlated with social, emotional and behavioural difficulties. The present study had a twofold aim. On the one hand it aimed at assessing Greek preschool children's social and nonsocial play, employing the Preschool Play Behaviour Scale, children's playfulness, employing Children's Playfulness Scale, and children's potential behaviour problems, with the Preschool Behaviour Questionnaire. On the other hand, it aimed at examining whether the types of play children engage in are predicted by their playfulness and by potential behaviour problems, as well as whether personal and family variables affect children's social and nonsocial play. Results suggest that the sample exhibits rather medium levels of nonsocial behaviours during play. Thus, correlation analysis showed that social and nonsocial types of play are predicted by playfulness components and that certain behavioural problems and personal and family characteristics are correlated with types of play. Implications are discussed and suggestions for future research are formulated.
Does phonology play a role when skilled readers read high-frequency words? Evidence from ERPs

We used event-related brain potentials to clarify the role of phonology in activating the meanings of high-frequency words during skilled silent reading. Target homophones (meet) in sentences such as The students arranged to meet in the library to study were replaced on some trials by either a high-frequency homophone mate (meat) or a spelling control word (mean). Differences between homophone errors and spelling controls were observed, both in the N400 component and in earlier time windows, suggesting that phonology continues to play a role in activating word meanings even for highly practiced words. A manipulation of the frequency of the correct target word provided evidence concerning the nature of the processing involved.
Relationship Between Traditional and Ballistic Squat Exercise With Vertical Jumping and Maximal Sprinting

Requena, B, García, I, Requena, F, Sáez-Sáez de Villarreal, E, and Cronin, JB. Relationship between traditional and ballistic squat exercise with vertical jumping and maximal sprinting. J Strength Cond Res 25(8): 2193-2204, 2011—The purpose of this study was to quantify the magnitude of the relationship between vertical jumping and maximal sprinting at different distances with performance in the traditional and ballistic concentric squat exercise in well-trained sprinters. Twenty-one men performed 2 types of barbell squats (ballistic and traditional) across different loads with the aim of determining the maximal peak and average power outputs and 1 repetition maximum (1RM) values. Moreover, vertical jumping (countermovement jump test [CMJ]) and maximal sprints over 10, 20, 30, 40, 60, and 80 m were also assessed. In respect to 1RM in traditional squat, (a) no significant correlation was found with CMJ performance; (b) positive strong relationships (p < 0.01) were obtained with all the power measures obtained during both ballistic and traditional squat exercises (r = 0.53-0.90); (c) negative significant correlations (r = −0.49 to −0.59, p < 0.05) were found with sprint times in all the sprint distances measured when squat strength was expressed as a relative value; however, in the absolute mode, no significant relationships were observed with 10- and 20-m sprint times. No significant relationship was found between 10-m sprint time and relative or absolute power outputs using either ballistic or traditional squat exercises. Sprint time at 20 m was only related to ballistic and traditional squat performance when power values were expressed in relative terms. Moderate significant correlations (r = −0.39 to −0.56, p < 0.05) were observed between sprint times at 30 and 40 m and the absolute/relative power measures attained in both ballistic and traditional squat exercises. Sprint times at 60 and 80 m were mainly related to ballistic squat power outputs. Although correlations can only give insights into associations and not into cause and effect, from this investigation, it can be seen that traditional squat strength has little in common with CMJ performance and that relative 1RM and power outputs for both squat exercises are statistically correlated to most sprint distances underlying the importance of strength and power to sprinting.
Examination of the Spanish Trait Meta-Mood Scale–24 Factor Structure in a Mexican Setting

The Trait Meta-Mood Scale (TMMS) is an emotional intelligence (EI) assessment originally developed for the U.S. population. This scale measures three EI factors—attention, clarity, and repair—to evaluate how an individual perceives one’s own EI skills. Although the TMMS has been adapted for use in several languages and cultures, the structure of the TMMS requires continuous examination across cultures. Specifically, there is a need for stronger validity evidence using confirmatory analyses. This study evaluates the factor structure of the TMMS-Spanish version, known as the TMMS-24, in a sample of students from northern Mexico. Data from high school and college students were used to examine the factor structure of the scale via confirmatory factor analysis. Results support the basis for future cross-cultural research conducted with Hispanic populations within Mexico with the TMMS-24.
Superficial Angiomyxoma of the Vulva in a Postmenopausal Woman: A Case Report and Review of Literature

Superficial angiomyxomas (SAMs) are rare benign cutaneous tumors that involve the subcutaneous layer. They are commonly located in the trunk, lower limbs and head or neck of women of reproductive age. SAMs in the vulva of postmenopausal women are especially rare case. Herein, we report a vulvar SAM in a postmenopausal 60-year-old woman. The patient presented with a palpable cutaneous mass in the right labium majora that had appeared 3 months earlier. The mass was slow growing and approximately 5 cm in size and resembled a soft tissue malignancy. It appeared as a well-defined multilocular cystic mass in magnetic resonance images. The preoperative diagnosis was a benign cystic lesion such as an epidermoid cyst. Grossly, the completely excised mass was 6 × 5 cm in size and well circumscribed with a multilocular outer surface, a yellowish-gray gelatinous cut surface, and a smooth rubbery inner surface. Histologic review revealed that the mass contained small to moderate amount of cellular angiomyxoid nodules and bland-looking spindle-shaped to ovoid cells without atypia. Neutrophil infiltration, which is a diagnostic feature of SAMs, was observed. Immunohistochemistry showed expression of CD34, but not of estrogen receptors, progesterone receptors, or desmin in the SAM. The patient has been followed up for 12 months without recurrence.
Sentinel node biopsy (SNB) in malignant melanoma as same day procedure vs delayed procedure: clinical and economic outcome

Abstract The aim of this study was to compare a delayed sentinel node biopsy (dSNB) procedure with a same-day procedure (sSNB) in malignant melanoma. In March 2012, Aarhus University Hospital went from the dSNB to the sSNB procedure defined by lymphoscintigraphy (LS) and sentinel node biopsy (SNB) performed on the same day. Before that time, LS was performed 24 hours prior to SNB. The aim was to investigate whether differences between the two procedures exist. Patients who underwent the SNB procedure between April and July 2011 and 2012, respectively, were included in the study. The criteria for SNB were malignant melanoma thickness >1 mm, Clark level IV/V, and ulcus or unknown thickness of the melanoma. All patients underwent re-excision and SNB at the same time. Pathological evaluation was not changed in the observation periods; however, the LS procedures varied. Only a minor turnover among the surgeons was observed. One hundred and eight patients were included in the study, 59 (dSNB) from 2011 and 49 (sSNB) from 2012, respectively. A median of 2.17 (dSNB) and 2.31 (sSNB) SLNs were removed, with no statistical differences. No difference in node positivity rates was observed. However, the number of hospitalisation days differed significantly, with 1.94 days in dSNB and 0.49 days in sSNB. Rates of complications at the site of the SNB procedure were similar. No differences in disease-free survival (DFS) or overall survival (OS) were recorded. SNB does not increase the overall survival. It is, therefore, essential to keep the morbidity and economic costs low, while keeping the quality of the procedure high.
Political Communication and Leisure

Leisure offers a dynamic contribution to the field of communication studies especially since it provides an ongoing contribution to the public domain (Goodale and Godbey, 1988). Leisure helps to cultivate communication competence for one's participation in any form of political engagement. Therefore, leisure philosophically enriches one's understanding and practice of political communication by transforming one's participation in the public domain. Many classical and contemporary texts from the Western tradition, including Aristotle's Politics, Cicero's Republic, and John of Salisbury's Policraticus suggest that leisure is fundamentally political and central to the public sphere. Both Western and Eastern political traditions also understand an interconnectedness between public political communicative engagement and philosophical leisure (Liu, 1955; Mills and Murphy, 1973; Lu, 1998; Dawson, 2002). This essay focuses on political communication and leisure specifically within a Western philosophical framework, asserting that political communication and leisure are inescapably linked.
