Parenteral Nutrition Therapy for an Achondroplastic Patient: Case Report
Get PDFIntroduction: Achondroplasia is the most common form of dwarfism in humans. At the end of the twentieth century, achondroplasia had its natural history investigated and its morbimortality understood. In dwarves, obesity is one of the causes of morbidity, and it is difficult to evaluate it due to the great disproportion among anthropometric data. The characterization of the nutritional needs of these patients represents an interesting dilemma for physicians. In view of these difficulties, the present case report describes an alternative to obtain the ideal weight value of an elderly dwarf in the use of parenteral nutritional therapy. Case Report: A 73-year-old male patient, carrier of achondroplastic dwarfism, was admitted for surgical treatment of colon adenocarcinoma. He was submitted to total colectomy with ileum-rectum anastomosis, evolving with abdominal septic shock by suture dehiscence, which was fixed, and a protective ileostomy was installed. Due to the maintenance of prolonged fasting, without the possibility of starting oral or enteral feeding, the patient used total parenteral nutrition. To estimate the total energy expenditure, we chose to ask the patient what his ideal weight was. The patient used total parenteral nutrition for eight days until he was able to meet his caloric needs orally. Conclusion: In the absence of indirect calorimetry, the ideal weight mentioned by the patient seems to be a good option for the estimation of the caloric expenditure by simplified equations
Miopia em crianças em fase escolar e a sua relação com o tempo de exposição a telas: uma revisão integrativa
Get PDFMyopia is becoming increasingly prevalent worldwide and can increase the risk of eye diseases such as glaucoma. Prolonged exposure to screens is a risk factor that has been associated with an increased risk of developing myopia in children. With the increasing use of electronic devices by children, it is important to better understand this relationship and evaluate screen use practices to prevent and treat myopia. There are few studies that address this topic in Brazil and worldwide. This study was an integrative analysis, carried out in six phases, according to the model outlined by Mendes, Silveira and Galvão. The systematic search/sampling was performed through an electronic search of the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Web of Science (Clarivate), Scientific Electronic Library Online (SCIELO), Scopus and Virtual Health Library (BVS) databases. Controlled descriptors from Medical Subject Headings (MeSH) and Health Sciences Descriptors (DeCS) were used to perform the bibliographic search in the databases, according to the following equation: “myopia” or “myopia” and “Criança” or “Child” and "Tempo de Exposição" or "Níveis Máximos Permitidos” or Threshold Limit Values". To determine the level of evidence of the selected articles, the classification proposed by the Agency for Healthcare Research and Quality (AHRQ) was adopted. The article selection process resulted in a total of 139 publications, of which 36 were excluded due to duplication, and 100 because they were not related to the theme of this review. Six articles were selected and the data were grouped into three categories, namely: 1- Mixed evidence on screen time and myopia; 2- Impact of screen time and outdoor activity on children with myopia; 3- Practical recommendations to mitigate the risk of myopia in children. This study found that some studies suggest a positive link, while others do not find a significant association, highlighting the need for more well-controlled research to better understand this relationship. Therefore, actions such as: limiting screen time, encouraging outdoor activities and adopting healthy visual habits may be effective strategies to mitigate the risk of developing myopia in children.

A busca/amostragem sistematizada foi realizada por meio da busca eletrônica às bases de dados Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Web of Science (Clarivate), Scientific Electronic Library Online (SCIELO), Scopus e Biblioteca Virtual em Saúde (BVS). Descritores controlados do Medical Subject Headings (MeSH) e Descritores em Ciências da Saúde (DeCS) foram utilizados para efetivar a busca bibliográfica nas bases de dados, conforme a seguinte equação: “miopia” or “myopia” and “Criança” or “Child” and " Tempo de Exposição" or " Níveis Máximos Permitidos” or Threshold Limit Values". Para determinar o nível de evidência dos artigos selecionados, adotou-se a classificação proposta pela Agency for Healthcare Research and Quality (AHRQ). O processo de seleção dos artigos resultou em um total de 139 publicações, sendo 36 excluídos devido à duplicidade, e 100 por não se relacionarem com o tema desta revisão. Foram selecionados seis artigos e os dados foram agrupados em três categorias, a saber: 1- Evidências mistas sobre o tempo de tela e miopia; 2- Impacto do tempo de tela e atividade ao ar livre nas crianças com miopia; 3- Recomendações práticas para mitigar o risco de miopia em crianças. Este estudo considerou que alguns estudos sugerem uma ligação positiva, outros não encontram uma associação significativa, destacando a necessidade de mais pesquisas bem controladas para entender melhor essa relação. Assim ações como: limitar o tempo de tela, incentivar atividades ao ar livre e adotar hábitos visuais saudáveis podem ser estratégias eficazes para mitigar o risco de desenvolvimento de miopia em crianças
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
