Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores
A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do municĂpio de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola nĂŁo vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, nĂŁo entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vĂnculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la EducaciĂł
Does the get up and go test improve predictive accuracy of the Triage Risk Screening Tool or Rowland questionnaire in older patients admitted to the emergency department?
Objectives: To assess the diagnostic characteristics of the get up and go test (GUGT) as a stand-alone test and in combination with the Flemish Triage Risk Screening Tool (fTRST) and Rowland questionnaire. One aim was to determine whether the diagnostic accuracy of these instruments could be improved for predicting unplanned emergency department (ED) readmission following ED discharge.
Methods: We carried out a prospective cohort study at the ED of the University Hospitals Leuven, Belgium. All patients aged at least 75 years (n=380) completed fTRST, Rowland, and GUGT testing at the index ED admission. Diagnostic characteristics for unplanned ED readmission were determined for hospitalized and discharged patients 1 and 3 months after the index ED visit.
Results: In both hospitalized and discharged patients, fTRST and Rowland (cut-off >=2) had good to excellent sensitivity and negative predictive value (NPV) but low to moderate specificity and accuracy; GUGT had low sensitivity and good to excellent NPV and specificity. The combined fTRST/GUGT or Rowland/GUGT had moderate to excellent NPV (56.3-94.3%). The combined fTRST (cut-off >=2)/GUGT had low sensitivity and moderate to excellent specificity. Sensitivity of the combined Rowland (cut-off >=4)/GUGT was good at the 1-month follow-up and moderate at the 3-month follow-up for hospitalized patients; it was low for discharged patients. Specificity was low for hospitalized patients and good for discharged patients.
Conclusion: Neither the objective measure of mobility (GUGT) nor the combined fTRST/GUGT or Rowland/GUGT improved the results. Our analysis shows that the predictive accuracy of the stand-alone, self-reported screening instruments fTRST and Rowland (cut-off=2) is still good. This study also confirmed their previously known limitations.status: publishe

Effect on Survival of Androgen Deprivation Therapy Alone Compared to Androgen Deprivation Therapy Combined with Concurrent Radiation Therapy to the Prostate in Patients with Primary Bone Metastatic Prostate Cancer in a Prospective Randomised Clinical Trial: Data from the HORRAD Trial
Background: The cornerstone of standard treatment for patients with primary bone metastatic prostate cancer (mPCa) is androgen deprivation therapy (ADT). Retrospective studies suggest a survival benefit for treatment of the primary prostatic tumour in mPCa, but to date, no randomised-controlled-trials (RCTs) have been published addressing this issue. Objective: To determine whether overall survival is prolonged by adding local treatment of the primary prostatic tumour with external beam radiation therapy (EBRT) to ADT. Design, setting, and participants: The HORRAD trial is a multicentre RCT recruiting 432 patients with prostate-specific antigen (PSA) >20 ng/ml and primary bone mPCa on bone scan between 2004 and 2014. Intervention: Patients were randomised to either ADT with EBRT (radiotherapy group) or ADT alone (control group). Outcome measurements and statistical analysis: Primary endpoint was overall survival. Secondary endpoint was time to PSA progression. Crude and adjusted analyses were applied to evaluate treatment effect. Results and limitations: Median PSA level was 142 ng/ml and 67% of patients had more than five osseous metastases. Median follow up was 47 mo. Median overall survival was 45 mo (95% confidence interval [CI], 40.4–49.6) in the radiotherapy group and 43 mo (95% CI: 32.6–53.4) in the control group (p = 0.4). No significant difference was found in overall survival (hazard ratio [HR]: 0.90; 95% CI: 0.70–1.14; p = 0.4). Median time to PSA progression in the radiotherapy group was 15 mo (95% CI: 11.8–18.2), compared with 12 mo (95% CI: 10.6–13.4) in the control group. The crude HR (0.78; 95% CI: 0.63–0.97) was statistically significant (p = 0.02). Conclusions: The current RCT comparing ADT to ADT with EBRT to the prostate in patients with primary bone mPCa did not show a significant difference in overall survival, although the CI cannot exclude a substantial survival benefit. Further research is needed to confirm our findings. Patient summary: This study investigated the effect of adding radiation therapy to the prostate to hormonal therapy in prostate cancer patients with metastasis to the bone at diagnosis. In our patient group, additional radiotherapy did not improve overall survival. Further research is needed to confirm our findings. Twitter summary: Adding radiotherapy to the prostate in patients with bone metastatic prostate cancer does not improve overall survival. In the current randomised controlled trial, there is no improvement in overall survival when comparing androgen deprivation therapy alone to androgen deprivation therapy with concurrent radiotherapy to the prostate in patients with primary bone metastatic prostate cancer
Rectal Culture-Based Versus Empirical Antibiotic Prophylaxis to Prevent Infectious Complications in Men Undergoing Transrectal Prostate Biopsy: A Randomized, Nonblinded Multicenter Trial.
BACKGROUND: An increase in infections after transrectal prostate biopsy (PB), related to an increasing number of patients with ciprofloxacin-resistant rectal flora, necessitates the exploration of alternatives for the traditionally used empirical prophylaxis of ciprofloxacin. We compared infectious complication rates after transrectal PB using empirical ciprofloxacin prophylaxis versus culture-based prophylaxis. METHODS: In this nonblinded, randomized trial, between 4 April 2018 and 30 July 2021, we enrolled 1538 patients from 11 Dutch hospitals undergoing transrectal PB. After rectal swab collection, patients were randomized 1:1 to receive empirical prophylaxis with oral ciprofloxacin (control group [CG]) or culture-based prophylaxis (intervention group [IG]). Primary outcome was any infectious complication within 7 days after biopsy. Secondary outcomes were infectious complications within 30 days, and bacteremia and bacteriuria within 7 and 30 days postbiopsy. For primary outcome analysis, the χ2 test stratified for hospitals was used. Trial registration number: NCT03228108. RESULTS: Data from 1288 patients (83.7%) were available for analysis (CG, 652; IG, 636). Infection rates within 7 days postbiopsy were 4.3% (n = 28) (CG) and 2.5% (n = 16) (IG) (P value = .08; reduction: -1.8%; 95% confidence interval, -.004 to .040). Ciprofloxacin-resistant bacteria were detected in 15.2% (n = 1288). In the CG, the presence of ciprofloxacin-resistant rectal flora resulted in a 6.2-fold higher risk of early postbiopsy infection. CONCLUSIONS: Our study supports the use of culture-based prophylaxis to reduce infectious complications after transrectal PB. Despite adequate prophylaxis, postbiopsy infections can still occur. Therefore, culture-based prophylaxis must be weighed against other strategies that could reduce postbiopsy infections. Clinical Trials Registration. NCT03228108
Cost Effectiveness of Rectal Culture-based Antibiotic Prophylaxis in Transrectal Prostate Biopsy: The Results from a Randomized, Nonblinded, Multicenter Trial.
BACKGROUND: Culture-based antibiotic prophylaxis is a plausible strategy to reduce infections after transrectal prostate biopsy (PB) related to fluoroquinolone-resistant pathogens. OBJECTIVE: To assess the cost effectiveness of rectal culture-based prophylaxis compared with empirical ciprofloxacin prophylaxis. DESIGN SETTING AND PARTICIPANTS: The study was performed alongside a trial in 11 Dutch hospitals investigating the effectiveness of culture-based prophylaxis in transrectal PB between April 2018 and July 2021 (trial registration number: NCT03228108). INTERVENTION: Patients were 1:1 randomized for empirical ciprofloxacin prophylaxis (oral) or culture-based prophylaxis. Costs for both prophylactic strategies were determined for two scenarios: (1) all infectious complications within 7 d after biopsy and (2) culture-proven Gram-negative infections within 30 d after biopsy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Differences in costs and effects (quality-adjusted life-years [QALYs]) were analyzed from a healthcare and societal perspective (including productivity losses, and travel and parking costs) using a bootstrap procedure presenting uncertainty surrounding the incremental cost-effectiveness ratio in a cost-effectiveness plane and acceptability curve. RESULTS AND LIMITATIONS: For the 7-d follow-up period, culture-based prophylaxis (n = 636) was €51.57 (95% confidence interval [CI] 6.52-96.63) more expensive from a healthcare perspective and €16.95 (95% CI -54.29 to 88.18) from a societal perspective than empirical ciprofloxacin prophylaxis (n = 652). Ciprofloxacin-resistant bacteria were detected in 15.4%. Extrapolating our data, from a healthcare perspective, 40% ciprofloxacin resistance would lead to equal cost for both strategies. Results were similar for the 30-d follow-up period. No significant differences in QALYs were observed. CONCLUSIONS: Our results should be interpreted in the context of local ciprofloxacin resistance rates. In our setting, from a healthcare perspective, culture-based prophylaxis was significantly more expensive than empirical ciprofloxacin prophylaxis. From a societal perspective, culture-based prophylaxis was somewhat more cost effective against the threshold value customary for the Netherlands (€80.000). PATIENT SUMMARY: Culture-based prophylaxis in transrectal prostate biopsy was not associated with reduced costs compared with empirical ciprofloxacin prophylaxis
Track Reconstruction with Cosmic Ray Data at the Tracker Integration Facility
The subsystems of the CMS silicon strip tracker were integrated and commissioned at the Tracker Integration Facility (TIF) in the period from November 2006 to July 2007.
As part of the commissioning, large samples of cosmic ray data were recorded under various running conditions in the absence of a magnetic field.
Cosmic rays detected by scintillation counters were used to trigger the readout of up to 15\,\% of the final silicon strip detector, and over 4.7~million events were recorded.
This document describes the cosmic track reconstruction and presents results on the performance of track and hit reconstruction as from dedicated analyses
