It\u27s okay, I\u27m a...teacher. Is professional status important to teachers?

Teacher accountability and the debate around teacher quality are issues of international importance. As society places increasing demands on the teaching profession, and regulatory bodies around the globe raise the ‘standards’ for teachers to adhere to, the professional status of teachers is drawn into focus. This paper reports research findings of an investigation into the perspectives of professional status of teachers, held by pre-service teachers about to embark on their teaching career. This was a comparative study whereby data were collected from an Australian university and an American university to explore professional status as an international issue. This quantitative study utilised a Likert scale to gather responses from participants. Data were analysed and findings from both universities indicated that professional status was a significant concern for pre-service teachers. Pre-service teachers felt that whilst they may have entered their teaching degree as a vocation, they hoped to receive status, as a professional, within society

Pulmonary metastasectomy in colorectal cancer: a prospective study of demography and clinical characteristics of 543 patients in the Spanish colorectal metastasectomy registry (GECMP-CCR)

ObjectivesTo capture an accurate contemporary description of the practice of pulmonary metastasectomy for colorectal carcinoma in one national healthcare system.DesignA national registry set up in Spain by Grupo Español de Cirugía Metástasis Pulmonares de Carcinoma Colo-Rectal (GECMP-CCR).Setting32 Spanish thoracic units.ParticipantsAll patients with one or more histologically proven lung metastasis removed by surgery between March 2008 and February 2010.InterventionsPulmonary metastasectomy for one or more pulmonary nodules proven to be metastatic colorectal carcinoma.Primary and secondary outcome measuresThe age and sex of the patients having this surgery were recorded with the number of metastases removed, the interval between the primary colorectal cancer operation and the pulmonary metastasectomy, and the carcinoembryonic antigen level. Also recorded were the practices with respect to mediastinal lymphadenopathy and coexisting liver metastases.ResultsData were available on 543 patients from 32 units (6–43/unit). They were aged 32–88 (mean 65) years, and 65% were men. In 55% of patients, there was a solitary metastasis. The median interval between the primary cancer resection and metastasectomy was 28 months and the serum carcinoembryonic antigen was low/normal in the majority. Liver metastatic disease was present in 29% of patients at some point prior to pulmonary metastasectomy. Mediastinal lymphadenectomy varied from 9% to 100% of patients.ConclusionsThe data represent a prospective comprehensive national data collection on pulmonary metastasectomy. The practice is more conservative than the impression gained when members of the European Society of Thoracic Surgeons were surveyed in 2006/2007 but is more inclusive than would be recommended on the basis of recent outcome analyses. Further analyses on the morbidity associated with this surgery and the correlation between imaging studies and pathological findings are being published separately by GECMP-CCR

Consumers’ questions about antipsychotic medication: revealing safety concerns and the silent voices of young men

PURPOSE: Little is known about consumer information needs regarding antipsychotic medicines. Medicines call centre (MCC)-derived data are underutilised; and could provide insight into issues of importance to consumers. This study aimed to explore consumers' information needs about antipsychotic medication sought from a national MCC in Australia. METHODS: Questions received by the National Prescribing Service Medicines Line relating to antipsychotic medication from September 2002 to June 2010 were examined by antipsychotic subclass and in relation to other medication queries. RESULTS: We identified 6,295 calls related to antipsychotic medication. While female callers predominated, the percentage of males with antipsychotic questions was statistically significantly higher than for other medication calls (33.9 vs 22.6 %; p < 0.001). There were distinct gender differences in medicines information seeking across age ranges. Younger men asked about second-generation antipsychotics, shifting toward first-generation antipsychotics after 45 years of age. Female interest in both subclasses was comparable, irrespective of age. Most callers asking about antipsychotics sought information for themselves (69.4 %). Callers were primarily concerned about safety (57.0 %), especially adverse drug reactions (28.8 %), and were more often prompted by a worrying symptom (23.8 %) compared with the rest of calls (17.2 %). Trends of antipsychotic questions received corresponded with antipsychotic prescription data. CONCLUSIONS: The number of calls received by this MCC over time reveals an ongoing consumer need for additional, targeted information about antipsychotics. Noticeable was the relatively high frequency of young male callers asking about antipsychotics, indicating that call centres could be a way to reach these traditionally poor users of health services

Fabrication of Polyimide-Matrix/Carbon and Boron-Fiber Tape

The term HYCARB denotes a hybrid composite of polyimide matrices reinforced with carbon and boron fibers. HYCARB and an improved process for fabricating dry HYCARB tapes have been invented in a continuing effort to develop lightweight, strong composite materials for aerospace vehicles. Like other composite tapes in this line of development, HYCARB tapes are intended to be used to build up laminated structures having possibly complex shapes by means of automated tow placement (ATP) - a process in which a computer-controlled multiaxis machine lays down prepreg tape or tows. The special significance of the present process for making dry HYCARB for ATP is that it contributes to the reduction of the overall cost of manufacturing boron-reinforced composite-material structures while making it possible to realize increased compression strengths. The present process for making HYCARB tapes incorporates a "wet to dry" process developed previously at Langley Research Center. In the "wet to dry" process, a flattened bundle of carbon fiber tows, pulled along a continuous production line between pairs of rollers, is impregnated with a solution of a poly(amide acid) in N-methyl-2-pyrrolidinone (NMP), then most of the NMP is removed by evaporation in hot air. In the present case, the polyamide acid is, more specifically, that of LaRC. IAX (or equivalent) thermoplastic polyimide, and the fibers are, more specifically, Manganite IM7 (or equivalent) polyacrylonitrile- based carbon filaments that have a diameter of 5.2 m and are supplied in 12,000-filament tows. The present process stands in contrast to a prior process in which HYCARB tape was made by pressing boron fibers into the face of a wet carbon-fiber/ poly(amide acid) prepreg tape . that is, a prepreg tape from which the NMP solvent had not been removed. In the present process, one or more layer(s) of side-by-side boron fibers are pressed between dry prepreg tapes that have been prepared by the aforementioned gwet to dry h process. The multilayer tape is then heated to imidize the matrix material and remove most of the remaining solvent, and is pressed to consolidate the multiple layers into a dense tape. For tests, specimens of HYCARB tapes and laminated composite panels made from HYCARB tape were prepared as follows: HYCARB tapes were fabricated as described above. Each panel was made by laying down ten layers of tape, containing, variously, one, two, or three boron-fiber plies and the remainder carbon- fiber-only plies (see figure). Each panel was made by laying down ten layers of tape. Each panel was then cured by heating to a temperature of 225 C for 15 minutes, then pressing at 200 psi (A1.4 MPa) while heating to 371 C, holding at 371 C for 1 hour, then continuing to hold pressure during cooling. Control specimens that were otherwise identical except that they did not contain boron fibers also were prepared. In room-temperature flexural tests, the HYCARB specimens performed comparably to the control specimens; in room-temperature, open-hole compression tests, the HYCARB specimens performed slightly better, by amounts that increased with boron content

Investigation of common, low-frequency and rare genome-wide variation in anorexia nervosa

Anorexia nervosa (AN) is a complex neuropsychiatric disorder presenting with dangerously low body weight, and a deep and persistent fear of gaining weight. To date, only one genome-wide significant locus associated with AN has been identified. We performed an exome-chip based genome-wide association studies (GWAS) in 2158 cases from nine populations of European origin and 15 485 ancestrally matched controls. Unlike previous studies, this GWAS also probed association in low-frequency and rare variants. Sixteen independent variants were taken forward for in silico and de novo replication (11 common and 5 rare). No findings reached genome-wide significance. Two notable common variants were identified: rs10791286, an intronic variant in OPCML (P=9.89 × 10−6), and rs7700147, an intergenic variant (P=2.93 × 10−5). No low-frequency variant associations were identified at genome-wide significance, although the study was well-powered to detect low-frequency variants with large effect sizes, suggesting that there may be no AN loci in this genomic search space with large effect sizes

Antifungal agents for invasive candidiasis in non-neutropenic critically ill adults: What do the guidelines recommend?

Objectives: Recommendations in clinical practice guidelines (CPG) may differ and cause confusion. Our objective was to appraise CPGs for antifungal treatment of invasive candidiasis (IC) in non-neutropenic critically-ill adult patients. Methods: We systematically searched the literature for CPGs published between 2008 and 2018. We assessed the quality of each guideline using six domains of the AGREE II instrument. We extracted and compared recommendations for different treatment strategies and assessed content quality.Results: Of 19 guidelines, the mean overall AGREE II score was 58%. The domain 'clarity of presentation' received the highest scores (88%) and 'applicability' the lowest (18%). CPGs provided detailed recommendations on antifungal prophylaxis (n = 10), with fluconazole recommended as initial prophylaxis in all seven CPGs citing a specific drug. Echinocandin was recommended as the initial drug in all 16 CPGs supporting empirical/pre-emptive treatment; and in 18 of 19 for targeted invasive candidiasis treatment. However, it remains unclear when to initiate prophylaxis, empirical or pre-emptive therapy or when to step down. Conclusions: The methodological quality of CPGs for antifungal treatment of IC in non-neutropenic critically-ill patients is suboptimal. Some treatment recommendations were inconsistent across indications and require local guidance to help clinicians make better informed decisions
