Introduction: hospital-acquired pressure ulcers (HAPU) represent a significant public health challenge. Understanding their main characteristics and related factors is essential for effective prevention. This article aims to analyse the main characteristics of HAPUs in four high-complexity hospital centres in Chile.Methods: secondary, analytical observational study. The sample (n=1000) included paediatric and adult patients. The study variables were the presence of HAPU, age, sex, dermatitis, risk of HAPU, change of position, pressure relief surface, immobilisation and speed of onset. Measurement of variables included physical examination and chart review. Descriptive statistics and multivariate logistic regression models were performed, accepting 95%CI, p<0,05.Results: a crude prevalence of 18,7 % was estimated. Most patients with HAPU were male (56,1 %), aged 18-59 years (39,6 %) and 60-80 years (39,0 %). On average, ten days elapsed from patient admission to the development of HAPU The most common stage was stage I (50 %), and the sacral region was the most frequent site of occurrence (30,1 %). The factor with the strongest association with having HAPU was having a high ulceration risk classification (OR 2,6, 95%CI1,5-4,4).Conclusions: this is the first study in Chile that showed the characterization of HAPU in a relevant sample of hospitalized patients. The relevant representative aspects for monitoring and preventing HAPU as its prevalence, location and factors associated with its appearance

Introduction: The "INTEGRA" methodology represents an updated approach for integrative reviews, emphasizing the quality of outcomes in response to a need expressed by the scientific community.Objective: To present the INTEGRA methodology and provide guidelines and recommendations for its application.Methods: This methodological study was conducted in two stages: a) Development of the guideline and b) Analysis. The study was carried out by a team of experts from Chile, Colombia, Mexico, Costa Rica, and Brazil, who met at least one of the following criteria: a) holding a doctoral degree or being a doctoral candidate with experience in conducting literature reviews; b) having experience in developing reviews for or with professionals in clinical-care settings, policymakers, government agencies, or other decision-makers.Results: The "INTEGRA" methodology consists of seven stages: 1. (I) Idea or study problem; 2. (N) Narrowing down the inquiry or objective; 3. (T) Targeting the search strategy; 4. (E) Execution or implementation of the search; 5. (G) Grading and quality control of the results; 6. (R) Reviewing the results; 7. (A) Analysis and discussion.Conclusions: The application of the "INTEGRA" methodology will provide authors with guidelines for developing integrative reviews and improving the quality of contributions in this field.

Introduction: prior to the COVID-19 pandemic, workers were exposed to psychosocial risks that were aggravated, negatively impacting their health. This has generated a boom in its study; however, theoretical ambiguities persist. Objective: to explain the theoretical ambiguity present in the study of psychosocial risks at work.Methods: the analytical article explores the theoretical ambiguity of psychosocial risks in the workplace. It incorporates various sources of information, including classical authors and contemporary approaches. Additionally, the authors offer critical insights and provide considerations for future research in the field.Result: there is a theoretical-conceptual ambiguity in the study of psychosocial risks at work. It is recommended: 1. To generate less abstract conceptual proposals to address semantic confusion and lack of taxonomic clarity. 2. Adopt an interdisciplinary conceptual approach that includes perspectives from psychology, sociology, and occupational health nursing. 3. Incorporate qualitative methodologies instead of continuing to use quantitative approaches, questioning the appropriateness of measuring a construct with traditional methods that have theoretical omissions. 4. develop unifying theoretical proposals.Conclusions: there is an urgent need for integrative theoretical proposals. In the opinion of the present authors, these proposals should have a low level of abstraction and include interdisciplinary perspectives that transcend psychology and sociology, as well as use qualitative methodologies

Introduction: Afaf Meleis's Transitions Theory addresses how multidimensional transitions impact individuals' health and well-being, emphasizing the importance of properly managing these transitions. This study aims to critically and reflectively describe this theory by analyzing its strengths, limitations, usefulness, and significance in nursing education. Method: Chinn and Kramer's theory analysis methodology was used. The description was based on publications from 1994 to 2010, and a critical reflection was performed by searching for evidence in PubMed and CINAHL between 2015 and 2021. The MeSH descriptors "Nursing Theory," "Models," and "Nursing" were used, along with the keywords "Transition" and "Transition Theory Meleis," resulting in a total of 16 selected articles. Results: The Transitions Theory has several strengths and limitations. Among its strengths are its high generalizability and accessibility, allowing for application in various clinical and educational contexts. However, the theory has limited semantic clarity and is complex, which may hinder its full understanding and application. Conclusions: The theory is highly valued in nursing education, providing a valuable theoretical framework for understanding and addressing student transitions. Its application allows for incorporating lived contexts into the educational process, creating equitable and student-centered learning environments. More research is needed in Latin America to evaluate its usefulness and adapt it to regional contexts, promoting meaningful learning both in the classroom and in clinical practice.
