    INTRODUCTION: Research to promote Computational Thinking (CT) has become frequent and carried out with the most different characteristics. Educational researchers argue that learning research needs to consider aspects of students' sociocultural context, regardless of what tools are used and how content is worked. However, it is not known if, and to what extent, these aspects are being considered in research to promote CT. OBJECTIVE: This research investigates whether the literature on initiatives to teach CT is recognizing and exploring aspects of students' sociocultural context and, mainly, how this is occurring. METHOD:A systematic review of the literature covering a decade (2007-2017) of articles published in the main vehicles of Computer Science in Education and Computer Science, considering the national and international scenario. RESULTS: The data indicate the students' sociocultural context is not being considered in the activities, although there is evidence that the scenario may be beginning to change. CONCLUSION: The results show that there is a growing concern and an evident effort by researchers to bring relevant elements of students' lives into the conducted practices. However, although it is possible to identify aspects of students' sociocultural context being considered by the mapped researches, it is still necessary to advance in terms of the rigor of the characterization of these aspects and the theoretical basis of the research

    Background: Data regarding response to treatment in lymphomatoid papulosis (LyP) are scarce. Aim: To assess the daily clinical practice approach to LyP and the response to first-line treatments. Methods: This was a retrospective study enrolling 252 patients with LyP. Results: Topical steroids, methotrexate and phototherapy were the most common first-line treatments, prescribed for 35%, 20% and 14% of the patients, respectively. Complete response (CR) was achieved in 48% of treated patients. Eczematous lesions significantly increased relative risk (RR) of not achieving CR (RR = 1.76; 95% CI 1.16-2.11). Overall median time to CR was 10 months (95% CI 6-13 months), and 78% of complete responders showed cutaneous relapse; both results were similar for all treatment groups (P > 0.05). Overall estimated median disease-free survival (DFS) was 11 months (95% CI 9-13 months) but DFS for patients treated with phototherapy was 23 months (95% CI 10-36 months; P < 0.03). Having the Type A LyP variant (RR = 2.04; 95% CI 0.96-4.30) and receiving a first-line treatment other than phototherapy (RR = 5.33; 95% CI 0.84-33.89) were significantly associated with cutaneous early relapse. Of the 252 patients, 31 (13%) had associated mycosis fungoides unrelated to therapeutic approach, type of LyP or T-cell receptor clonality. Conclusions: Current epidemiological, clinical and pathological data support previous results. Topical steroids, phototherapy and methotrexate are the most frequently prescribed first-line treatments. Although CR and cutaneous relapse rates do not differ between them, phototherapy achieves a longer DFS. Presence of Type A LyP and use of topical steroid or methotrexate were associated with an increased risk of early relapse

    Ten Years of Initiatives to Promote Computational Thinking: A Systematic Mapping of Literature

    INTRODUCTION: Computational Thinking is a problem solving skill that became well known after Wing's article in 2006. Since then, several researchers have argued this way of thinking can be useful to all people, and much research has been done to promote the development of this skill with different audiences. OBJECTIVE: To discover the state of art of the initiatives carried out in the last decade to promote the development of Computational Thinking, inside and outside Brazil, regardless of the public addressed and the method applied. METHOD: A systematic mapping of the literature was carried out comprising three steps of selection of articles to proceed with data extraction and analysis of results. Three international databases and one national were included to search articles published between 2007 and 2017, in Portuguese and English. From a total of 468 articles, 46 were selected for data extraction and analysis. RESULTS: Mapping allowed us to answer seven research questions, showing, for example, that the USA and Brazil stand out in quantity of research. Additionally, they presented important differences between the duration of the research, target audience(s) and the tools used. We were able to identify that research has grown in number and diversity. Conversely, initiatives in multi and transdisciplinary contexts are still lacking, and little attention is paid to the public in less favored contexts. CONCLUSION: Computational Thinking is a growing topic of research and knowing the initiatives published in these 10 years of research helps in the elaboration of new research, mainly indicating opportunities to be explored. Especially for Brazil, it is necessary to approach students beyond basic education, to explore the transdisciplinary potential of Computational Thinking, and to carry out research of longer duration
