Control Attitudes Scale-Revised-Brazilian Version.

BACKGROUND: Heart failure demands self-care skills and behaviors that can be negatively impacted by a low level of perceived control (PC), a belief about having the necessary resources to deal with negative events. Having valid and reliable instruments to measure PC is important to support interventions that improve self-care and related outcomes. The Control Attitudes Scale-Revised (CAS-R) was developed in the United States to measure PC in cardiac conditions. In Brazil, there are no instruments available to measure this construct. OBJECTIVE: The aims of this study were to translate and adapt the CAS-R to the Brazilian population and to assess the content validity of the adapted version. METHODS: The CAS-R was translated, back-translated, and assessed by an expert committee for linguistic equivalences. An agreement > 80% was considered adequate. Content validity (clarity, theoretical relevance, and practical pertinence) was assessed by both an expert professional panel (n = 6-8) and a panel of patients with heart failure (n = 40). A content validity coefficient > 0.70 was considered acceptable. RESULTS: The translations to Brazilian Portuguese were considered consistent with the original CAS-R. In the third round of linguistic equivalence assessment, all items achieved acceptable agreement, except for 2 items. After modifications to the instrument to achieve adequate equivalences, the adapted version had a final content validity coefficient of 0.93. Most patients were able to understand the instrument. CONCLUSIONS: The CAS-R-Brazilian version is equivalent to the original CAS-R and has satisfactory evidence of content validity. Additional psychometric testing will be performed to allow for the assessment of PC in individuals with heart failure in Brazil.

Cross-cultural adaptation for Brazil and validity of a guide to assist nursing students' clinical reasoning.

PURPOSE: To assess the validity of a Written Clinical Reasoning Prompt (WCRP) to help nursing students' clinical reasoning (CR). METHOD: This is a methodological study of translation and cross-cultural adaptation into Brazilian Portuguese of instruments that aim to promote CR improvement, composed of (1) WCRP; (2) two case studies; (3) a questionnaire about students' perceptions during decision-making in case studies; (4) a scoring rubric for correcting case studies. For translation and cross-cultural adaptation, stages 1-8 of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Consortium Network were adopted. Agreement values among experts >80% and content validity coefficient (CVC) > 0.8 were considered satisfactory. For the pretest, a randomized clinical trial was carried out with 24 nursing students (intervention group, n = 14, using the WCRP to solve case studies; control group, n = 10, without using the WCRP). FINDINGS: The WCRP was translated and adapted into Brazilian Portuguese, requiring minimal adjustments to obtain agreement among the judges above 80% and CVC above 0.80. Regarding face validation, an adequate agreement was obtained in the assessment by students. There was no difference in the accuracy of nursing diagnoses between the intervention and control groups in the pretest. CONCLUSION: The WCRP was translated and adapted into Brazilian Portuguese and had adequate face and content validity estimates; however, there was no association with improving nursing students' diagnostic accuracy. IMPLICATIONS FOR NURSING PRACTICE: The translated and adapted versions of all instruments into Brazilian Portuguese had adequate evidence of content and face validity. The use of WCRP was not associated with a significant improvement in nursing students' diagnostic accuracy. New studies with larger samples, a sample power of at least 80%, and a level of significance of 5% are needed.

Development and validation of an educational video on nasopharyngeal and oropharyngeal suctioning.

OBJECTIVE: The objective of this study was to develop and validate an educational video on nasopharyngeal and oropharyngeal suctioning. BACKGROUND: The use of videos in nursing education can improve students' skills in performing procedures. DESIGN: This was a methodological study. METHODS: This study was performed in five steps: (1) development of the script for an educational video on nasopharyngeal and oropharyngeal suctioning; (2) content validation of the script by 10 nurse specialists; (3) development of the video; (4) content validation of the video by six nurse specialists; (5) cognitive testing by 51 nursing students regarding the understanding of the items, until the following requirements were met: (1) mean and median scores ≥4, with significant inter-rater agreement, according to the Wilcoxon test; (2) 95% confidence intervals >80 for the proportion of maximum scores, according to the binomial distribution. p values <0.05 were considered significant. RESULTS: After four rounds of evaluation by the specialists, the script was considered validated. The video was considered validated after two rounds of evaluation by specialists and students (p < 0.001). The video addressed the following topics: concept, indications, contraindications, required materials, appropriate technique, nursing notes and complications. CONCLUSIONS: The video script was created by using the Storyboard technique and validated by specialist nurses using the Delphi technique. Nursing students watched, analyzed and understood the video which may support them to improve their technical skills of this procedure.

Evidencia científica sobre la aplicabilidad del ácido ascórbico en lesiones cutáneas / Scientific Evidence regarding the Applicability of Ascorbic Acid against Skin Lesions

Introducción: Las lesiones cutáneas se caracterizan por la ruptura de la continuidad del tegumento que resulta de varios factores. Así, la atención médica de las personas con lesiones cutáneas debe ser multidimensional e interdisciplinaria entre los profesionales de la salud. Una de las alternativas terapéuticas que viene ganando espacio en el tratamiento de pacientes con lesiones cutáneas es el uso de productos naturales, como el ácido ascórbico. Objetivo: Analizar la mejor evidencia científica sobre el uso del ácido ascórbico como método terapéutico en lesiones cutáneas. Métodos: Revisión sistemática, donde se buscaron estudios en las bases de datos Pubmed, Scopus, Cinahl, Web of Science y The Cochrane Data Base, con investigación dirigida a la aplicabilidad del ácido ascórbico en las lesiones de la piel. Los estudios se analizaron de forma pareada y se clasificaron con respecto a su mejor evidencia científica. Conclusión: Después de analizar los ensayos clínicos, que presentaron solidez científica, se notó que hay un fomento de la contribución del ácido ascórbico a la curación, ya que disminuye el proceso inflamatorio y conduce a la neovascularización, la concentración de macrófagos y la concentración de fibroblastos y fibras de colágeno. Entre los estudios analizados, se evidencia que el uso del ácido ascórbico tiene un efecto en el proceso terapéutico en pacientes con lesiones, pero requiere nuevos estudios para complementar esta tesis(AU)

Introduction: Skin lesions are characterized by break in the continuity of tissue resulting from several factors. Therefore, the medical care provided to people with skin lesions must be multidimensional and interdisciplinary. One of the therapeutic alternatives that is increasingly being used for the treatment of patients with skin lesions is the use of natural products, such as ascorbic acid. Objective: To analyze the best scientific evidence on the use of ascorbic acid as a therapeutic method against skin lesions. Methods: Systematic review consisting in search for studies in the databases Pubmed, Scopus, Cinahl, Web of Science and The Cochrane Data Base, with research directed to the applicability of ascorbic acid against skin lesions. The studies were paired and ranked according to their best scientific evidence. Conclusion: After analyzing the clinical trials, which presented scientific solidity, it was noted that there is some promotion of the contribution of ascorbic acid to healing, since it decreases the inflammatory process and leads to neovascularization, to concentration of macrophages, as well as of fibroblasts and collagen fibers. Among the studies analyzed, it is evidenced that the use of ascorbic acid has an effect on the therapeutic process of patients with injuries, but new studies are required to complement this thesis(AU)

Cross-cultural adaptation of the caregiver contribution to heart failure self-Care into Brazilian Portuguese and content validation.

BACKGROUND: The Caregiver Contribution to Heart Failure Self-Care (CACHS) is a Canadian instrument that assesses caregivers' (CGs) contributions to heart failure (HF) patients' self-care, but a Brazilian version was lacking. AIMS: To adapt CACHS into Brazilian Portuguese and to estimate the content validity of the adapted version. METHODS: A psychometric study of cross-cultural adaptation and content validation was conducted. Linguistic equivalence was assessed by eight professional experts. Content validity was assessed by an expert professional panel (n=8; for clarity, theoretical relevance and practical relevance) and a CG panel (n=46; for cognitive debriefing of the adapted instrument). In the cultural adaptation, the items were considered equivalent if experts reached an agreement ≥80%. In the content validation, the items were considered acceptable if content validity coefficients (CVC) were ≥0.70. RESULTS: The translated version was considered consistent with the original CACHS by the authors. In the second round of linguistic equivalence assessment, all items achieved 100% agreement, except for one item, which presented 75% agreement in conceptual equivalence. The CVC in the first and second rounds of content validity assessment by experts was 0.80 to 0.90. During cognitive testing, the CGs requested explanations on three items, which were reformulated. All CGs then understood the Brazilian version of CACHS, named CACHS - Versão Brasileira (CACHS-Br). CONCLUSIONS: CACHS-Br is equivalent to the original version and provided satisfactory evidence of content validity. Further psychometric testing of this version should allow for the measurement of the CG contributions to HF self-care in Brazil.

Risk of venous thromboembolism and implementation of preventive measures. / Riesgo de tromboembolismo venoso e implementación de medidas preventivas.

OBJECTIVE: To identify the frequency of risk factors for venous thromboembolism in hospitalized medical patients and the use preventive measures by healthcare professionals. METHOD: A descriptive, cross-sectional, retrospective study including medical charts of 369 adult patients hospitalized in the Medical sector of a university hospital in São Paulo, Brazil, for at least 48h from 2015 to 2017. Sociodemographic data, clinical risk factors for venous thromboembolism, contraindication and implementation of chemical prophylaxis, and the occurrence of the disease were investigated. The use of preventive measures was calculated by following the guidelines of the Brazilian Society of Clinical Medicine and the risk of venous thromboembolism according to the Padua Prediction Score (high risk ≥ 4 and low risk < 4). RESULTS: The prevalence of venous thromboembolism was 7.3% (n = 27). All patients had at least one risk factor for venous thromboembolism, the most prevalent being reduced mobility (74.2%), active cancer (70.7%), infection (27.1%), recent surgery (21.6%) and age ≥70 years (20.0%). Chemical prophylaxis was implemented in 70.3% of high-risk patients without contraindication and mechanical prophylaxis was applied in only one of the cases with an indication. CONCLUSIONS: All patients had at least one risk factor for venous thromboembolism. However, there was a low rate of implementation of preventive measures by health care professionals. Therefore, there is a need for multiple interventions, including admission and permanent education of nurses regarding risk and prevention, warning systems and outcomes audit.

Efficacy of a video during bed bath simulation on improving the performance of psychomotor skills of nursing undergraduates: A randomized clinical trial.

BACKGROUND: Studies have shown the efficacy of videos used in isolation to retain knowledge, acquire skills, and establish students' self-confidence. A few studies have investigated the efficacy of videos associated with simulations, while none of these studies have addressed bed bathing, one of the first procedures learned by nursing students. OBJECTIVE: To test the efficacy of a video-assisted bed bath simulation on improving the performance of psychomotor skills of undergraduate nursing students. DESIGN: A randomized clinical trial. SETTING: A Teaching Skills and Simulation Center at a Federal University in Brazil. PARTICIPANTS: All students regularly enrolled in the second year of the nursing undergraduate program at a Federal University, aged 18 years old, who had never performed a bed bath and had attended a theoretical class addressing the procedure (n = 56). METHODS: The students were randomized into two groups: the Control group (n = 28) simulated a bed bath with the instructions of a tutor, while the Intervention group (n = 28) watched a video during the bed bathing simulation, under the supervision of a tutor. The performance of students concerning bed bathing was assessed twice (before and after the simulation) using a previously validated instrument. RESULTS: The psychomotor skills of both groups significantly improved in the second assessment, and the Intervention group scored higher (p = 0.003). CONCLUSIONS: The use of a video during bed bath simulations was efficacious for improving the performance of psychomotor skills of undergraduate nursing students.

Prevalence and Associations Between Related Factors and Defining Characteristics of the Nursing Diagnosis Sedentary Lifestyle in Patients with Acute Coronary Syndrome.

PURPOSE: To identify the prevalence of Sedentary Lifestyle (SL) and associations between its defining characteristics (DC) and related factors (RF) in patients with acute coronary syndrome (ACS). DATA SOURCES: 123 patients with ACS were assessed for SL through the International Physical Activity Questionnaire. Associations between DC and RF was investigated by Pearson's Chi square and Fisher's exact test. DATA SYNTHESIS: 56.1% had SL. Insufficient motivation and Insufficient resources for physical activity were associated with two DC. CONCLUSION: SL was frequent and there were associations between RF and DC. IMPLICATIONS FOR NURSING PRACTICE: Multi-professional interventions should aim at motivating patients to adopt physical activities.

Correlations between stress, anxiety and depression and sociodemographic and clinical characteristics among outpatients with heart failure.

Aim To describe and investigate correlations among anxiety, stress and depression and identify their relationship with sociodemographic and clinical characteristics of patients with heart failure. METHODS: This is an analytical cross-sectional study. Sociodemographic and clinical characteristics were collected, along with levels of anxiety, stress and depression from 309 outpatients. RESULTS: The mean levels of stress, anxiety and depression were correlated but low. Time since diagnosis, the disease's functional class, family income, and smoking influenced stress. Functional class and Chagas disease influenced anxiety and depression. Being unemployed and smoking influenced anxiety, while being a homeowner influenced depression. CONCLUSION: These findings should be considered when planning nursing interventions.

Conceptual and Operational Definitions of the Defining Characteristics and Related Factors of the Diagnosis Ineffective Health Management in People With Heart Failure.

OBJECTIVE: To construct conceptual and operational definitions for the defining characteristics (DCs) and related factors (RFs) of the nursing diagnosis (ND) ineffective health management for people with chronic heart failure. METHOD: Conceptual and operational definitions for the DC and RF were based on studies found in an integrative literature review in the databases Latin American Literature in Health Sciences, Cumulative Index to Nursing and Allied Health Literature, and MEDLINE by using the key words Nursing diagnosis, Heart Failure, and Patient Cooperation in different combinations. RESULTS: Conceptual and operational definitions for all the DCs and RFs were constructed. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The definitions will facilitate in the identification of ND in clinical practice in patients with heart failure, future research on ND validation, and education in undergraduate courses.

Cardiovascular changes resulting from sexual activity and sexual dysfunction after myocardial infarction: integrative review.

AIMS AND OBJECTIVES: To identify studies on cardiovascular changes resulting from sexual activity, as well as the occurrence of sexual dysfunction after acute myocardial infarction. BACKGROUND: Many patients with acute myocardial infarction experience sexual dysfunction, mainly due to fear of dying and/or of having another heart attack. DESIGN: The research was an integrative literature review. METHODS: Searched databases included Lilacs, Medline and PubMed, and the following were inclusion criteria: national and international articles published from 2000-2011, written in Portuguese, Spanish or English. RESULTS: The results indicate that many patients with coronary heart disease experience sexual dysfunction whether from fear of experiencing another acute myocardial infarction or due to the side effects of medication. Studies show there are few cardiovascular changes during sexual activity. CONCLUSIONS: Because sexual dysfunction negatively affects the lives of people, providing guidance to individuals with cardiovascular disease, especially after an acute myocardial infarction, may be a crucial factor in determining quality of life and should be incorporated into clinical practice. RELEVANCE TO CLINICAL PRACTICE: Despite the subject's importance, there are few studies on nursing guidance concerning sexual activity; moreover, addressing sexuality with patients is still a challenge for nurses.
