Effects of prolonged fasting on the preterm newborn
(Universidad Privada Norbert Wiener, 1905-07-09) Bartolo Calderón, Julia Lourdes; Ordinola Maza, Milagros; Rivera Lozada de Bonilla, Oriana
Determine the effects of prolonged fasting in the preterm newborn. Material and methods: Observational and retrospective systematic review, the search has been restricted to articles with full text. Results: In the final selection, 10 articles were chosen, we found that 30% (03) correspond to Spain, with 20% (02) we find Colombia, while with 10% (01) we find Turkey, Madrid, United Kingdom United, Mexico and Cuba, respectively. Most experimental studies have been studied, with 30%, mainly in Türkiye, the United Kingdom and Colombia. Among systematic reviews 30% in Spain and Madrid. And Quasi experimental with 10% in Spain. We find Cuba, Colombia and Mexico, with 10%. Belonging to cross-sectional descriptive studies. Conclusions: According to the research reviewed, the effects produced by prolonged fasting in the preterm newborn are gastrointestinal alterations: such as atrophy of the gastric mucosa and villi, reduction of enzymes producing the appearance of Necrotizing Enterocolitis. Among the metabolic ones: we have the appearance of oxidative stress and metabolic disorders

Enzymatic effect of detergents diluted with tap water vs soft water in cleaning instruments
(Universidad Privada Norbert Wiener, 1905-07-09) Reisman Remuzgo, Delicia Mercedes; Gómez Gonzales, Walter Edgar
Objective: Establish the enzymatic effect of detergent dilutions: Soft water vs tap water in cleaning hospital instruments. Material and methods: Observational and retrospective systematic review, the search has been restricted to full-text articles, the selected articles were subjected to a critical reading, using Jover's evaluation to identify their degree of evidence. Results: In the final selection, 08 articles were chosen, we found that 60% correspond to Brazil, with 20% we find Cuba, and finally with 10% Mexico and Venezuela respectively. The investigations were experimental and a corresponding systematic review. 62.5% of scientific production comes from Brazil, while Mexico, Cuba and Venezuela constitute 12.5% each. Of the total number of articles analyzed, 30% affirm that the conditions and quality of water are important for adequate cleaning processes and other procedures related to health, 30% are related to the properties, characteristics and conditions in which enzymes exert adequate performance. Finally, 40% were related to the processes and interventions that revolve around the use of enzymatic detergents. Conclusions: The use of soft water in the dilution of the enzymatic detergent maintains the properties and chemical activity of the enzymes efficiently, allowing their action against organic matter.

Interference due to turbidity (lipemia) in the determination of enzymes of clinical interest - Lima - 2023
(Universidad Privada Norbert Wiener, 2024-06-30) Helguera Carrasco, Alicia; Saldaña Orejón, Italo Moisés
Analytical interference is one of the main causes of clinically significant bias in the measurement of biological magnitudes. Lipemia-induced turbidity is one of the most common pre-analytical interferences in the clinical laboratory. The objective is to assess the effect of lipemia-induced turbidity in serum samples on the evaluation of the most common enzymes. Methods: A pre-experimental design was used with pre-test and post-test with a single group. From a pool of sera, seven aliquots were prepared to which increasing amounts of a lipid emulsion were added to mimic turbid samples, and one aliquot without the added interferent was used as a control. Results: The enzyme activity values for amylase, lipase, AST, and ALT were above the tolerability limits, while the bias in enzyme activities of FAL, GGT, CK, and LDH did not exceed these thresholds. Conclusion: Lipemia-induced turbidity significantly affected the enzymes amylase, lipase, AST, and ALT, while no significant effect was observed for the enzymes FAL, GGT, CK, and LDH.
