(Universidad Privada Norbert Wiener, 2018-08-04) Santa Cruz Saavedra, Grace Vanessa; Prado Vidal, Rosaura Micaela; Avila Vargas Machuca, Jeannette Giselle
Objective: To systematically analyze the available evidence from studies on the effectiveness of vitamin A and iron supplementation in the prevention of anemia in children under 5 years of age. Materials and Methods: The systematic review of 10 scientific articles found on the effectiveness of vitamin A and iron supplementation in the prevention of anemia in children under 5 years of age was conducted using the following databases: Cochrane, Lilacs, Scielo, Medline, PubMed. All articles were analyzed according to the grading scale to determine their strength and quality of evidence. Results: 90% (9/10) demonstrate the effectiveness of vitamin A and iron supplementation in preventing anemia in children under 5 years of age, while 10% of the reviewed articles conclude that more studies are needed to demonstrate the effectiveness of vitamin A and iron supplements in preventing anemia in children under 5 years of age. Conclusions: Of the 10 articles systematically reviewed, 9 articles show the effectiveness of vitamin A and iron supplementation in preventing anemia in children under 5 years of age, while 2 articles conclude that larger population studies are needed to demonstrate the effectiveness of vitamin A and iron supplementation in preventing anemia.

Effectiveness of the management of calcium concentrations in the dialysis liquid in the reduction of complications in patients with chronic renal insufficiency submitted to hemodialysis
(Universidad Privada Norbert Wiener, 2020-02-29) Tello Bardales, Gina Lizeth; Ugarte Palacin, Lisbeth Katherine; Matta Solis, Hernan Hugo
Objective: To study and structure the effectiveness of managing calcium concentrations in dialysate fluid in reducing complications in patients with chronic kidney disease undergoing hemodialysis. Material and Methods: A review of scientific articles was conducted, including observational, prospective, and retrospective quantitative studies, subject to analytical selection, using the GRADE tool for assessing the level of evidence. Articles were found in the following information sources: Journal of the Spanish Society of Nephrology, PLOS ONE Medicine, Therapeutic Apheresis and Dialysis, Clinical Journal of the American Society of Nephrology, Medicine (Baltimore), and Scientific Reports. Of the 10 articles reviewed, 40% (n=4/10) were randomized controlled clinical trials, 20% (n=2/10) pre-experimental studies, 20% (n=2/10) case and cohort/case-control studies, 10% (n=1/10) analytical cross-sectional study, and 10% (n=1/10) cohort study. The studies originated from the following countries: Spain (40%), United States (20%), Japan (20%), South Korea (10%), and Italy (10%). Results: The studies show that 100% (n=10/10) of the reviewed articles indicate that managing calcium concentrations in dialysate fluid reduces complications in patients with chronic kidney disease undergoing hemodialysis. Conclusion: Managing calcium concentrations in dialysate fluid is effective in reducing complications in patients with chronic kidney disease undergoing hemodialysis.

Protective effect of calcium present in dairy products in reducing the risk of colorectal cancer
(Universidad Privada Norbert Wiener, 2024-07-27) Condo Leonardo, Diana Alejandrina; Bohórquez Medina, Andrea Lisbet
Colorectal cancer originates in the colon or rectum, typically beginning with the rapid growth of altered morphology cells that divide, grow, and spread, affecting various tissue parts, starting with a polyp that can evolve into carcinoma or CCR. In this regard, improving dietary and environmental factors will not only reduce the future risk of cancer. This secondary research, titled 'Critical Review: Protective Effect of Calcium in Dairy Products on the Reduction of Colorectal Cancer Risk', aimed to highlight the benefits of consuming dairy products and derivatives in reducing colorectal cancer mortality rates and improving quality of life. The critical review concluded that various studies support the idea that the intake of total dairy products and derivatives reduces the risk of colorectal cancer, with mechanisms such as calcium and other nutrients in dairy products playing a protective role.

Use of adenosine versus calcium channel antagonists for the care of patients with supraventricular tachycardia in the emergency room
(Universidad Privada Norbert Wiener, 2020-08-02) Castillo Lazo, Gilmer Eduardo; Soto López, Karla Alexandra; Fernández Rengifo, Werther Fernando
Objective: Systematize the evidence on the use of adenosine compared to calcium channel antagonists in the treatment of supraventricular tachycardia in the emergency room. Material and methods: Algorithms were created and a search was carried out in the PubMed, Cochrane, TripdataBase and PlosOne metadata. Results: A total of 1915 studies were found and of them ten were included in the study. Two publications are from the United Kingdom, two from the USA, two from Australia, one belongs to Singapore, another to Uruguay, another from Germany, and the last from India. Conclusion: According to this review, the quality of the evidence is medium and high and the strength of the recommendation is high only in three articles reviewed. The seven studies affirm that the efficacy of adenosine and calcium channel blocker products are similar in effectiveness. Both medications differ in their side effects: Adenosine due to redness, nausea, chest pain and headache. Calcium channel antagonists have been shown to produce hypotension.
