Corrosion of surgical instruments due to the use of common water vs distilled water
(Universidad Privada Norbert Wiener, 1905-07-09) Castillo Sánchez, Rosa María; Gómez Gonzales, Walter Edgar
Objective: Determine if the corrosion of surgical instruments is produced by the use of common water vs. distilled water. Materials and Methods: Systematic Reviews are an observational and retrospective research design, which synthesizes the results of multiple primary investigations. They are an essential part of evidence-based nursing due to their rigorous methodology, identifying relevant studies to answer specific questions of clinical practice. Results: In the final selection, 13 articles were chosen, we found that 31% (4) correspond to Spain, 14% (2) correspond to Colombia and Chile, with 7% (1) Cuba, Mexico, Peru were found. , Venezuela and Brazil respectively. 69% were experimental studies from the countries of Spain, Peru, Mexico, Colombia, Venezuela and Chile. With 31% we have cross-sectional studies belonging to Brazil, Chile, Spain, and Cuba. Of the total number of articles analyzed, 80% concluded that plain water causes corrosion in surgical instruments. It was evident in the reviewed research that stainless steel instruments should not be subjected to cleaning, disinfection and sterilization processes, whose dilution component is common water, nor should they be immersed in a physiological salt solution. Prolonged contact and immersion in the solution causes corrosion pitting and forms stress corrosion cracking. Conclusion: It is recommended to use distilled water to avoid corrosion of surgical instruments, especially for final rinsing, after cleaning and disinfection.

(Universidad Privada Norbert Wiener, 1905-07-09) Salazar Calderón, Katherine; Amésquita Ortiz, Ana Cecilia; Gómez Gonzales, Walter Edgar
Objectives: Determine the effectiveness of nursing educational intervention in the self-care of patients with heart failure. Materials and Methods: Systematic review of 8 articles which allow us to analyze the positive impact of the educational intervention provided by the nursing professional to patients with heart failure. In the final selection, 8 articles were chosen, we found that 37.5% (3) correspond to Colombia, 25% (02) to Brazil, 25% (02) to Spain, while with 12.5% (01) we find Mexico . Results: In this systematic review of the total number of articles analyzed, 100% affirm that nursing educational interventions are effective for the self-care of patients with heart failure. The nursing educational intervention must be individualized and comprehensive when addressing the patient with Heart Failure, promoting self-care and containing aspects such as weight control, salt and fluid restriction, medications, exercise, diet and symptoms of worsening of the disease. Conclusions: All studies show that nursing intervention contributes beneficially to the self-care of patients with heart failure.

Efficacy of the Mediterranean diet in reducing the risk of breast cancer in premenopausal and postmenopausal women
(Universidad Privada Norbert Wiener, 2020-12-27) Ramos Astucuri, Norma; Llapa Lescano, Lenny Nataly; Avila Vargas Machuca, Jeannette Giselle
Objective: Systematize the evidence on the effectiveness of the Mediterranean diet in reducing the risk of breast cancer in premenopausal and postmenopausal women. MATERIAL AND METHOD: The study has a systematic, observational and retrospective review design; of articles with full text, which identified their grade or quality of evidence according to the Grade System. The population was made up of 10 articles obtained from the following databases Pubmed, Embase, Cochrane Library, Dialnet, Scielo and Lilacs. 70% correspond to systematic reviews and 30% to randomized clinical trials, from the countries of the United States 30% (03/10), Spain 30% (03/10), Austria 20% (02/10), China 10% ( 01/10) and Italy 10% (01/10). Results: All the studies reviewed demonstrate that the Mediterranean diet is effective in reducing the risk of breast cancer in premenopausal and postmenopausal women. Conclusions: The Mediterranean diet, based on a balanced diet, very low in fats, sugars and salt; and rich in fruits, vegetables, legumes and whole grains is effective in reducing the risk of breast cancer in premenopausal and postmenopausal women; In postmenopausal women its protective effect is higher.

(Universidad Privada Norbert Wiener, 1905-07-09) Callacna Silva, Miriam del Pilar; Deza Arana, María Sabina; Rivera Lozada de Bonilla, Oriana
Methodology: It is a systematic review of 10 articles, 30% from Colombia, 20% from Peru, Mexico and Ecuador respectively and 10% from Panama. The majority of articles are case-control studies with 70% and 30% cross-sectional studies. These articles were obtained from the Pubmed and scielo databases. Results: the 10 articles reviewed show that the risk factors for gastric cancer are: 40% salt, 30% alcohol consumption, 20% having a family history, not using adequate refrigeration to preserve food and low level of education, as well as foods exposed to smoke, cooking with firewood, consuming reheated foods, low consumption of fruits and vegetables and tobacco respectively. And 10% have inadequate eating habits, physical inactivity and a sedentary lifestyle, stress, pharmacological habits, as well as low socioeconomic level, being over 50 years old, having H. Pylori, consumption of red pork meat and sausages. 3 times a week and be female. Conclusion: High consumption of salt, as well as alcohol, constitutes 70% of the risk factors for gastric cancer.
