All rights reserved. Introduction: Dyslipidemia and excess weight in adolescents are risk factors for the development of cardiovascular diseases both in this period and in adulthood. Materials and methods: a cross-sectional descriptive study was carried out that included 74 third and fourth year students of the “Private Educational Unit “Universi-tary of Azogues”, to which the body mass index (BMI) was determined from the weight and height, proceeding later to the extraction of a blood sample for the assessment of the lipid profile. Total cholesterol (TC), HDL-cholesterol (c-HDL) and triglycerides (TG) levels were determined using commercial kits (Spinreact®) and LDL-cholesterol (c-LDL) according to Human Frisonex®. Results: It was evidenced in the analysis that 70.3% of students had normal weight and 29.7% were overweight. 35.1% had CT levels in the limit and 9.5% were high. 51.3% showed TG levels and in 9.5% they were high. 94.6% had acceptable levels of c-HDL and c-LDL. 8.1% of the overweight students had high levels of CT and TG. Conclusions: 29.7% of adolescents were overweight and a significantly higher percentage (8.1%) high levels of CT and TG. The percentages of adolescents with overweight, limit and high levels of CT and TG suggest the need to follow them.
Optimization of water use in a rapid filtration system: a case study
(2020) García Ávila, Fausto Fernando; Zhindon Arevalo, Cesar Edmundo; Alvarez Ochoa, Robert Ivan; Donoso Moscoso, Silvana Patricia; Flores Del Pino, Lisveth
The objective of this research was to reduce water use during the operation of anthracite-sand filters used for treating drinking water. The variables that affect the saturation of the filter bed were evaluated, using procedures proposed by the Pan American Center for Sanitary Engineering and Environmental Sciences (CEPIS). The following were evaluated: filtration velocity, initial filtration quality, filtration runs duration, filter bed expansion, duration of the washing process, washing velocity, granulometry, and mud balls. The results obtained were compared with the design parameters recommended by CEPIS. Maximum turbidity of 0.5 NTU was obtained. Filtration runs were in the lower limit of the range indicated by CEPIS. The filter medium expansion in five of the eight filters was lower than recommended by CEPIS. The optimal washing time was 18 min. The washing velocity was low producing little filter bed expansion. The granulometric result indicated that the effective size and the anthracite uniformity coefficient were different between filters. The results also presented significant improvements in the filtration process and the amount of water saved once the filter washing process was optimized. The results also demonstrated that measuring filters performance could improve the filtration system efficiency and ensure the drinking water quality.

Introduction: pain is the main reason for consultation after traumatology surgeries since they are usually longer procedures generating greater pain in the patient, reason for which the objective of the present analysis was to describe the treatment of post-surgical pain in the service of traumatology in a second level hospital. Materials and methods: this was a descriptive cross-sectional study in 101 individuals older than 12 years who presented a diagnosis of limb fractures admitted to the traumatology service of a second level hospital in the province of Cañar-Ecuador from January to July 2017. Describing the analgesic therapy used for the assessment of patients. Results: 101 cases were evaluated of which 67.3% were represented by the male sex and 32.7% by the female, 52.5% of the fractures were found in the upper limbs and 47.5% in the lower ones, the location most frequent was the radius and ulna, the predominant surgery was the open reduction of osteosynthesis with 60.4% of the cases, the most used analgesic treatment was ketorolac (93%), either as monotherapy 46.5% or associated to other drugs such as tramadol or metamizole 46.5%. The most used combination was ketorolac plus tramadol 45.5%. Of the total combined analgesic prescriptions, 49.5% use two analgesics as therapy. Tramadol was used in more than half of the 52.5% prescriptions. Conclusions: currently in the present health center the most frequent fractures were those of upper limbs and the predominant analgesic therapy was ketorolac and the combination most used was with tramadol.
