Institutional experience of PTH evaluation on fine-needle washing after aspiration biopsy to locate hyperfunctioning parathyroid tissue

Assaying parathyroid hormone (PTH) in the washing liquid after fine-needle aspiration biopsy (FNAB) seems to be a valid approach to locate parathyroid tissue. PTH-FNAB was evaluated in 47 patients with a clinical picture of primary hyper-parathyroidism (PHP) and ultrasonography (US) suggestive of parathyroid lesion. The patients were subdivided into two groups on the basis of the absence or presence of US thyroid alterations. The result of PTH-FNAB was compared with those of cytology, scintigraphy and, in 24 patients, surgical outcome. PTH-FNAB samples with a value higher than that recorded in the serum and higher than our institutional cut-off were deemed to be probable samples of parathyroid tissue. Cytology proved diagnostic for benign thyroid lesions, non-diagnostic for thyroid lesions, hyperplastic parathyroid tissue, undetermined or malignant thyroid lesions and other lesions in 45%, 30%, 17%, 4%, and 4% of cases, respectively. In 47% of cases, PTH-FNAB indicated that the sample had been taken in parathyroid tissue. In patients without US alterations, the diagnostic accuracy of PTH-FNAB was greater than that of scintigraphy. After surgery, comparison between the results of PTH-FNAB and scintigraphy, in terms of positive predictive value (PPV), revealed the superiority of PTH-FNAB; PPV was 94% for FNAB and 71% for scintigraphy, while sen-sitivity was 83% and 69%, respectively. PTH-FNAB evaluation after FNAB appears to be more diagnostic than cytology and scintigraphy. Of all the procedures used, PTH-FNAB appears to be the method of choice when the target is US suggestive and reachable. PTH-FNAB appears to be a useful method of guiding surgical intervention.     

Measuring zoo visitor learning and understanding about orangutans: evaluation to enhance learning outcomes and to foster conservation action

Despite the endangered status of the orangutan, very little research has sought to understand what people know about this species or the conservation challenges they face. As zoos are well placed to influence such understandings, the present study sought to explore knowledge following a visit to orangutan exhibits at three Australian zoos (N?=?240). Two learning assessments were utilised, capturing (1) self-reported learning and (2) understandings in relation to the information zoos prioritise for inclusion on exhibit signage. The relationship between the latter, attitudes toward orangutans and intentions for future conservation behaviour were also explored. Higher knowledge scores were significantly (indirectly) associated with intentions for future conservation behaviour through higher attitudes (indirect effect?=?0.15, std. error?=?.05, z?=?3.12, p?R²?=?20.3). The importance of enhancing visitor understandings (e.g. through improved exhibit design and signage displays, and through encouraging repeat zoo visits) for conservation action is discussed.     

Attitudes toward science: measurement and psychometric properties of the Test of Science-Related Attitudes for its use in Spanish-speaking classrooms

Understanding attitudes toward science and measuring them remain two major challenges for science teaching. This article reviews the concept of attitudes toward science and their measurement. It subsequently analyzes the psychometric properties of the Test of Science-Related Attitudes (TOSRA), such as its construct validity, its discriminant and concurrent validity, and its reliability. The evidence presented suggests that TOSRA, in its Spanish-adapted version, has adequate construct validity regarding its theoretical referents, as well as good indexes of reliability. In addition, it determines the attitudes toward science of secondary school students in Santiago de Chile (n?=?664) and analyzes the sex variable as a differentiating factor in such attitudes. The analysis by sex revealed low-relevance gender difference. The results are contrasted with those obtained in English-speaking countries. This TOSRA sample showed good psychometric parameters for measuring and evaluating attitudes toward science, which can be used in classrooms of Spanish-speaking countries or with immigrant populations with limited English proficiency.     

Menstrual cycle alters training strain,monotony, and technical training length in young

The menstrual cycle (MC) phases carry to several psychophysiological alterations; however, no study has investigated the impact of MC phases on training load or technical training. In the present study, we investigated the effect of the follicular phase (FP), ovulatory phase (OP), and luteal phase (LP) on training load and technical training in young athletes. Twelve female athletes performed regular daily training sessions with the rating of perceived exertion (RPE) and duration being registered every session. Training impulse (TRIMP), monotony and strain were calculated. MC symptoms, RPE, and duration were also measured during technical training, which was carried out on a specific day during each phase. The TRIMP was not affected by MC phases during regular training (p > .05), but training monotony and strain were higher in FP compared to OP (p < .05). During the technical training, MC phases did not affect RPE (p > .05), but the session was longer in both FP and LP, compared to OP (p < .05). MC symptoms were exacerbated in FP compared to both OP and LP (p < .05). These findings suggest that MC disorders were elevated during FP, which indicate that monitoring MC phases might provide important feedbacks for programming training and expected results during competitions.     

Through the Screen,into the School: Education,subversion, ourselves in The Simpsons

There is little question that popular television shows influence the shaping of social norms, identities, and the ways we navigate daily life. High profile shows are also a common magnet for critical attention. No primetime television show has provoked as wide a range of reactions as Fox's The Simpsons. From shock radio to public broadcasting pundits pour condemnations, accolades, and adulations for this unique cartoon sitcom. From the masses to the literary elite, the world's most famous animated family touch one and all, from the raw funny bone to the higher intellect. In a parallel vein, there is no lack of strong and varied opinion regarding education in the USA, and few venues do a more effective job at representing its core controversies than this weekly cartoon. Here I angle a mirror at the primetime television screen and suggest some ways this animated series reflects inner, outer, and systemic relationships with education. The beauty of The Simpsons in this regard is that the translucent motility of an ostensibly average nuclear family in the anywhere USA town of Springfield buffers the gaze just enough to allow us room to laugh, however uneasily.     

In‐service Training of Primary School Teachers: an Example with the use of Computers

An approach effective in helping primary school teachers master thermal phenomena is presented. It is centred on experimental activities of teachers and the use of computer simulations closely linked to their laboratory activity. Teachers’ ideas on the subject and their difficulties are reported jointly with remedy strategies.     

Scaffolding Preservice Science Teachers' Evidence-Based Arguments During an Investigation of Natural Selection

In this qualitative case study, preservice science teachers (PSTs) enrolled in their advanced methods course participated in a complex, data-rich investigation based on an adapted version of the Struggle for Survival curriculum. Fundamental to the investigation was the use of the Galapagos Finches software and an emphasis on giving priority to evidence and constructing evidence-based arguments. The questions that guided the research were: (1) What is the nature of the scientific arguments developed by PSTs? (2) How do PSTs go about constructing scientific arguments (emphasis on processes and strategies)? (3) In what ways do the scaffolds embedded in the Galapagos Finches software influence the development of PSTs arguments? Two pairs of PSTs were selected for in-depth examination. The primary sources of data were the electronic artifacts generated in the Galapagos Finches software environment and the videotaped interactions of both pairs as they investigated the data set, constructed and revised their arguments, engaged in peer review sessions, and presented their arguments to the class at the end of the unit. Four major patterns emerged through analysis of the data. First, using the software, PSTs consistently constructed claims that were linked to evidence from the investigation. Second, although PSTs consistently grounded their arguments in evidence, they still exhibited a number of limitations reported in the literature. Third, the software served as a powerful vehicle for revealing PSTs knowledge of evolution and natural selection. Finally, the PSTs approach to the task had a strong influence on the way they used the software.     

African American Counselor Educators: Their Experiences,Challenges, and Recommendations

This study examined tie career experiences of African American counselor educators in programs accredited by the Council for Accreditation of Counseling and Related Educational Programs. Results indicated that African American counselor educators perceived publishing, colleagues' racism, and lack of mentoring as major barriers to the attainment of promotion and tenure. Implications for future research are presented.     

Dialectical Behavior Therapy in College Counseling Centers: Current Trends and Barriers to Implementation

The purpose of this study was to examine trends and barriers in implementation of dialectical behavior therapy (DBT) programs in college counseling centers (CCCs). Participants were 107 CCC employees who participated in an electronic survey. One third of respondents endorsed use or planned use of DBT at their centers. The most prevalent primary mode of DBT offered was group skills training. Highly endorsed barriers to implementation included productivity demands and lack of individual therapists, time for team consultation, and willingness to offer phone coaching. Suggested implementation strategies include developing community partnerships, use of virtual teams, supporting programs with campus data, and adapting DBT strategically.
