Algorithms for the management of scars: the importance of systematizing behaviors

Introduction: Pathological scars occur from the hyperproliferation of fibroblasts and can be classified into hypertrophic scars and keloids. Basically, hypertrophic scars do not grow beyond the limits of the original wound, while keloids grow horizontally in a nodular form. Despite the diversity of instruments used to guide the prevention, treatment and follow-up of pathological scars, there is a need for instruments that address local realities. The objective is to carry out a narrative review of the literature on scar management algorithms and create an updated algorithm. Methods: Descriptive study of narrative literature review, with a search in PubMed, SciELO, LILACS, MEDLINE and Cochrane databases, from November 2010 to November 2020, published in English, Portuguese and Spanish. The descriptors used were: “cicatrix,” “keloid,” “algorithms,” and “wound healing.” The sample selection consisted of identifying the articles, reading the titles and abstracts, and selecting studies related to the topic. Subsequently, the full reading of the selected studies and classification according to the eligibility criteria were carried out. Results: 209 articles were found, and 116 were eliminated due to duplicity, resulting in 45 articles. A total of 8 articles that met the inclusion criteria were identified. Four articles were excluded after analysis and consensus meeting due to the absence of algorithms with scientific rigor; this study is composed of four articles. Conclusion: Four algorithms were found in the literature review that resulted in the development of an updated algorithm for scars

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
