    Clinical-epidemiological characteristics of patients hospitalized with urinary tract infections caused by BLEE-producing Enterobacteriaceae at Carlos Lanfranco La Hoz Hospital, 2017
    (Universidad Privada Norbert Wiener, 2019-05-07) Villarreal Guevara, Nathaly Marbelly; Benites Azabache, Juan Carlos
    This research is a descriptive, cross-sectional, and retrospective study. A total of 148 data points from patients were collected, including age, sex, source service, prior antibiotic use, hospitalization time, and the enterobacteria isolated in their urine cultures. The statistical software EpiInfo and Excel were used for frequency analysis and graphical representation. The results showed that the prevalence of patients with UTIs positive for extended-spectrum beta-lactamase (ESBL)-producing enterobacteria was 23.2%. Of the 148 cases, 81.8% were women, the mean age was 49.4 years, 66.2% came from general medicine, the average hospitalization time was 12.3 +/- 13.5 days, and 68.9% of the enterobacteria isolated and positive for ESBL were Escherichia coli. The most frequent comorbidities were diabetes and hypertension, and 26.3% of the patients had received ceftriaxone prior to confirmation of infection by ESBL.

    Hemoglobin relationship and erythrocyte distribution width in patients with different degrees of severity of covid 19, Hospital Carlos Lanfranco la Hoz in the period from july to december 2020
    (Universidad Privada Norbert Wiener, 2023-08-20) Villarreal Guevara, Nathaly Marbelly; Huamán Cárdenas, Victor Raul
    SARS-CoV-2 infection spreads between individuals through emitted aerosols. The objectives are to determine the relationship between hemoglobin and erythrocyte distribution width with different degrees of severity of COVID-19 at Carlos Lanfranco Hospital in 2020; to determine hemoglobin levels and erythrocyte distribution width in COVID-19 patients, and to determine the severity proportion in COVID-19 patients. Data collection will occur in the hematology area of the laboratory, reviewing clinical records of patients admitted for COVID-19. Hemoglobin levels and erythrocyte distribution width will be collected, along with age, sex, and severity level. Frequency analysis will be performed for COVID-19 positive cases between July and December 2020, along with statistical techniques including chi-square, t-test, and logistic regression. The EpiInfo statistical software will be used.
