Scientific writing in English is a daunting task for non-native English speakers. The challenges of writing in a foreign language are evident in the scientific literature where texts by non-native English-speaking scientists tend to be less clear and succinct, contain grammatical errors, and are often rejected by prestigious journals.
To distinguish between malignant and benign lesions of the thyroid gland histological demonstration is often required since the fine-needle aspiration biopsy method applied pre-operatively has some limitations. In an attempt to improve diagnostic accuracy, markers using immunocytochemistry and immunohistochemistry techniques have been studied, mainly cytokeratin-19 (CK-19), galectin-3 (Gal-3) and Hector Battifora mesothelial-1 (HBME-1). However, current results remain controversial. The aim of the present article was to establish the diagnostic accuracy of CK-19, Gal-3 and HBME-1 markers, as well as their associations, in the differentiation of malignant and benign thyroid lesions.
Burnout syndrome is typified by three dimensions: emotional exhaustion (EE), depersonalization (DP) and low personal accomplishment (PS), and is prevalent among cancer care providers. The objective is to conduct a systematic review and meta-analysis of studies that evaluated the presence of burnout syndrome in professionals dedicated to the care of cancer patients. A search was conducted of the MEDLINE, LILACS and COCHRANE databases. Articles were selected that had used the Maslach questionnaire to assess burnout syndrome prevalence, had evaluated at least 35 subjects (including physicians), had at least a 20% questionnaire response rate, and that were published in English, Spanish or Portuguese. Ten studies (2375 participants) were included in this analysis. Severe involvement by any one of the three dimensions ranged from 8% to 51%. The overall prevalence of EE was found to be 36% [95% confidence interval (CI) (31-41)], while for DP this was 34% [95% CI (30-39)] and for PS 25% [95% CI (0.16-34)], demonstrating considerable heterogeneity across studies. The prevalence of burnout syndrome is elevated among cancer professionals throughout the world but varies substantially among studies. Further research is needed to better understand and prevent this syndrome.
Background: Recombinant granulocyte colony-stimulating factors (G-CSFs) such as Filgrastim are used to treat chemotherapy-induced neutropenia. We investigated a new G-CSF, XM02, and compared it to Neupogen™ after myelotoxic chemotherapy in breast cancer (BC) patients. Methods: A total of 348 patients with BC receiving docetaxel/doxorubicin chemotherapy were randomised to treatment with daily injections (subcutaneous 5 μg/kg/day) for at least 5 days and a maximum of 14 days in each cycle of XM02 (n = 140), Neupogen™ (n = 136) or placebo (n = 72). The primary endpoint was the duration of severe neutropenia (DSN) in cycle 1. Results: The mean DSN in cycle 1 was 1.1, 1.1, and 3.9 days in the XM02, Neupogen™, and placebo group, respectively. Superiority of XM02 over placebo and equivalence of XM02 with Neupogen™ could be demonstrated. Toxicities were similar between XM02 and Neupogen™. Conclusion: XM02 was superior to placebo and equivalent to Neupogen™ in reducing DSN after myelotoxic chemotherapy. Trial Registration: Current Controlled Trials ISRCTN02270769
Burnout syndrome which is prevalent among oncologists is characterized by three aspects: emotional exhaustion, depersonalization and low personal accomplishment. The purpose was to evaluate prevalence of the burnout syndrome among Brazilian medical oncologists and the variables that correlate with its presence. A survey was conducted with members of the Brazilian Society of Medical Oncology (SBOC) who received three questionnaires (general, Maslach burnout questionnaire and an opinion survey) mailed to all 458 members. Response rate was of 22.3%. According to the criteria proposed by Grunfeld, which consider burnout present when at least one of the aspects is severely abnormal, prevalence of this syndrome was 68.6% (95% confidence interval, CI: 58.68% to 77.45%). By multivariate analysis having a hobby/physical activity, a religious affiliation, older age, living with a companion and rating vacation time as sufficient were correlated significantly and independently with burnout syndrome. The burnout syndrome is prevalent among Brazilian oncologists. Oncologists having sufficient personal and social resources to engage in a hobby, physical activity, have enough vacation time and religious activities are at lower risk of developing burnout.
