Objective: To evaluate the relationship between uremic index (UI) and renal function measured by creatinine clearance (CrCl) in persons with normal renal function and in those with chronic renal failure (CRF), as well as to compare the renal function extrapolated from serum creatinine and that calculated with equations internationally recommended. Methods: A cross sectional study was conducted including patients attended in outpatient clinics at Hospital Cayetano Heredia in Lima from June 2018 to June 2019. Pearson’s correlation between UI and CrCl was calculated; comparison of means of UI, serum creatinine and standard equations was done by ANOVA and eta square. Results: the overall UI was 4.37 ± 4.99 mg/dl and correlated linearly with CrCl (r=-0.74, p=0.000). The UI and the log UI were significantly more predictive of CrCl than serum creatinine and the international equations used. ...

OBJETIVE: To compare the effect of abdominal hysterectomy type on female sexual function. MATERIALS AND METHODS: prospective descriptive study, according to the design 'only after', held at the Regional Hospital of Trujillo, Peru, in which 54 women undergoing total abdominal hysterectomy (HAT) and 54 women who underwent subtotal hysterectomy (HAST ) for benign disease between January 2001 and December 2003; They were randomly selected to answer a questionnaire that evaluates their sexual function (FSFI). The proportions of dysfunction scores each of the domains of sexual function were determined, as well. Comparisons were made using the chi-square test, z-test of proportions and the test 't'. RESULTS: The proportion of sexual dysfunction in patients undergoing high as (40.7%) was lower than in those undergoing HAT (48.1%), with no statistically significant difference (p> 0.05), and there...

The study of executive functions is a subject that arouses the interest of researchers in neuropsychology and neuroscience. In particular, the evolutionary aspects of these neuropsychological functions, in an effort to be able to identify the way in which these functions appear in the child and how they take shape in adolescence, is a topic under exploration. The present investigation sought to determine if there were differences in the evolution of executive functions in children differentiated in age groups: 6-7 years, 8-9 years, 10-12 years. For this, the Battery of executive functions was used: BANFE 2, by Flores, Ostrosky and Lozano (2014). This is a basic research with a comparative descriptive design. The results showed significant differences in working memory and executive functions according to age range. This is particularly appreciated in the functions of Visuospatial Working...

Objective: To compare the professional performance of the health establishments with essential obstetric and neonatal functions from Lima with respect provincie during September-October of 2015. Materials and methods: It´s a cross- sectional analytical investigation conducted in 350 health establishments with essential obstetric-neonatal functions I-II (FONE I-II) database based on national surveys conducted by the National Institute of Statistics and Informatics (INEI) during 2015. New variables were created from the databases to determinate the gynecology staff´s professional performance and analyzed the data with the R statistical software and the IBM SPSS Statistics 25 using the chi-square test. Results: The investigation showed that midwifes were the healthl staff who most frequently attended vaginal births, both in Lima (62.9%) and in provinces (91.4%). With respect to the partog...

Polyethylene terephthalate (PET) is a widely used material in container manufacturing, particularly in bottle production. It is characterized by its low cost and widespread availability. However, its improper disposal has significantly exacerbated global plastic pollution. For instance, less than 50% of plastic bottles are recycled. Moreover, studies indicate that this issue has led to a significant accumulation of plastic waste in the oceans, which continues to grow annually and could be considered floating islands of debris. This study proposes replacing PET with polylactic acid (PLA), a biodegradable and biocompatible polymer with suitable properties for bottle production. PLA also has a shorter decomposition time compared to PET, contributing to the reduction of carbon footprint and greenhouse gas emissions. The research methodology included a diagnostic phase to define objectives, i...

This research aimed to compare the internalizing (anxiety and depression) and externalizing (hyperactivity) symptoms of Caraquenian children based on the level of food insecurity reported by their parents. A simple retrospective design was proposed with a sample of 200 children, aged between eight and twelve, and their representatives, in charge of reporting the food insecurity levels in their homes and the symptoms of perceived hyperactivity in their children. For the analysis of results, the non-parametric Mann-Whitney´s U technique was used to compare anxiety, depressive and hyperactive symptoms based on high and low levels of food insecurity. Results suggest moderate conditions of food insecurity in the households. Furthermore, regarding the set of internalizing symptoms evaluated, it was found that households with greater food insecurity tend to have children with greater manifesta...

Recent studies report a high prevalence of psychotic and substance use disorders sharing common brain mechanisms that may affect cognitive performance, response to treatment, the ability to commit to it and, consequently, increase the risk of relapse. Objective: To compare cognitive performance in patients with alcoholism and schizophrenia. Material and Methods: Observational study designed to evaluated 18 patients with schizophrenia and 32 with mental disorders due to alcohol consumption. The short neuropsychological battery NEUROPSI, validated in Spanish, was the main study instrument. Results: Significant differences were found between both groups in areas of executive function and long-term memory, with the sub-group of patients with schizophrenia showing greater deterioration levels. Conclusion: The results assist in explaining and understanding the difficulties that patients with s...

Background: COVID-19 is a disease that since its appearance in 2019 has represented a challenge for health services. The sequelae are a consequence of a deterioration in the quality of life, fatigue, dyspnea and joint pain. Objective: Compare physical, respiratory, cognitive and functional independence functional parameters in post-COVID-19 patients, with respiratory sequelae before and after a respiratory physical and occupational therapy program. Methods: A comparative, quasi-experimental, prospective study was conducted in outpatients discharged from hospitalization due to COVID-19 in a 3rd level hospital of the Instituto Mexicano del Seguro Social in Puebla, Mexico during 2020-2021. Scales were applied before and after the rehabilitation program. Descriptive statistics were used. Results: We included 116 patients, 57.7% men, mean age 47.32 years (min. 20, max. 79); 77 (66.3%) patient...

The objective of this work was to compare different approaches that allow a better characterization of the environmental quality using benthic macroinvertebrates as indicators in rivers of the southwestern highlands. The study was developed with data from the hydrobiology monitoring of the Quellaveco Project between the years 2013-2015, with which we obtained quality indices (ABI, EPT, IMEERA and SVAP), community structure indices (Shannon, Simpson, N1 of the Hill and Pielou series) and functional diversity indices (richness, diversity, dissimilarity and functional equity, and Rao’s Q). The results of the multivariate analyzes showed that the rates of functional diversity, Simpson’s index and IMEERA have significant representativeness in the study units. We concluded that functional diversity indices can be alternative to traditional and environmental quality indices, in addition to ...
