Ítem Acceso abierto Agreement in the Count and Morphological Identification of Platelets in Blood Smears Between Medical Technologists from Hospitals and Specialized Institutes in Metropolitan Lima and Callao, October 2017 – March 2018(Universidad Privada Norbert Wiener, 2018-05-31) Conde Sanabria, Ricardo; Rodríguez Ruiz, Lucía Raquel; Alegre Torres, Justo TobíasThe objective is to find the degree of concordance in platelet count and morphological identification on blood smears between Medical Technologists. The study is descriptive, prospective, and cross-sectional. During the sampling period, 106 Medical Technologists working in the Hematology area participated. A 14-question questionnaire, 3 stained blood smears, and 4 platelet morphology images were validated by 3 expert judges. To measure the degree of concordance, Cohen's Kappa coefficient was used. A Kappa coefficient of 0.309, indicating weak agreement for platelet counting on blood smears, and a Kappa of 0.429, indicating moderate agreement for platelet morphological identification, were obtained. To ensure the reliability of the blood smear study, proper sample collection, smear specifications as per CLSI, optimal staining, good review technique, experienced analysts, and quality control programs should be considered. Promoting consensus on hematological cytomorphology is essential to standardize the diverse criteria used today.Ítem Acceso abierto Alterations in Blood Cell Counts in Adult Patients with Secondary Erythrocytosis Due to Heart Disease at a Health Institution Specialized in Cardiovascular Diseases in Lima, 2016-2017(Universidad Privada Norbert Wiener, 2018-06-12) Muñoz Farroñay, Annette del Belén; Saavedra Moscol, Daniel; Mengolé Amaya, Pedro AlfonsoThe objective was to identify alterations in corpuscular constants in adult patients with erythrocytosis secondary to heart diseases at a healthcare institution specializing in cardiovascular diseases in Lima, during the period from 2016 to 2017. The study was descriptive, retrospective, and cross-sectional. A total of 125 hemogram results from patients who met the inclusion criteria were collected. It was found that 78% of the patients' results were normocytic normochromic and 22% were microcytic hypochromic. Of the latter, 71% had CHCM within the reference values, while 29% had CHCM below the reference value. The most represented age group was young adults, comprising 64% of the results, followed by middle-aged adults at 28% and older adults at 8%. Regarding hemoglobin, hematocrit, and erythrocyte count values, a predominance of male patients was found. This study provides more information on the behavior of hematological values and corpuscular constants in patients with erythrocytosis secondary to heart disease, offering quantitative data that may assist clinical laboratory professionals.Ítem Acceso abierto Association between biofilm formation and the production of extended-spectrum beta-lactamases in Escherichia coli isolated from urine culture at Hipólito Unanue National Hospital, January to June 2018(Universidad Privada Norbert Wiener, 2019-01-23) Hurtado Quispe, Luz Melina; Casablanca Alvarado, Juana; Champi Merino, Roky GovanniThe objective was to determine the association between biofilm formation and the production of extended-spectrum beta-lactamases (ESBL) in Escherichia coli isolated from urine cultures at the Hipólito Unanue National Hospital from January to June 2018." A quantitative, observational, and cross-sectional study was conducted. The Jarlier method was used to demonstrate ESBL production, and the Tissue Culture Plate (TCP) method was used to assess biofilm formation. The variables were described using absolute and percentage frequencies, and the association between the variables was determined using the Chi-square test. Out of 190 Escherichia coli strains isolated from urine cultures, 48.9% produced ESBL and 73.2% were biofilm producers, with 58.3% weak, 30.2% moderate, and 11.5% strong biofilm formation.Ítem Acceso abierto Bacteremia related to intravascular catheters in hospitalized neonates, Hipólito Unanue National Hospital 2016-2017(Universidad Privada Norbert Wiener, 2020-09-04) Liñan Vega, Maria Angelica; Zarate Salvador, Merli Dionisia; Rivera Lozada de Bonilla, OrianaBacteremia encompasses a wide variety of clinical manifestations. In this research, 514 samples (257 blood cultures and 257 intravascular catheter samples) were collected from patients in the neonatology service of the National Hospital Hipólito Unanue over the years.Ítem Acceso abierto Carbapenemases in Pseudomonas aeruginosa in Isolates from Hospitalized Patients of a National Hospital in San Juan de Miraflores, January to June 2017, Lima(Universidad Privada Norbert Wiener, 1905-07-09) Carranza Vásquez, Sherley Merlid; Vasquez Quispe, Walter Ivan; Olivo Lopez, Jose MariaPseudomonas aeruginosa is one of the most common pathogens causing infections in hospitalized patients and produces various resistance mechanisms, among which carbapenemases that hydrolyze all beta-lactams are significant. The objective of our study was to determine the types of carbapenemases found in Pseudomonas aeruginosa isolates from hospitalized patients at a national hospital in San Juan de Miraflores, Lima in 2017. A basic, descriptive, prospective, and cross-sectional study was conducted, including 150 non-repeated Pseudomonas aeruginosa isolates from hospitalized patients, with sensitivity tests performed by disk diffusion according to CLSI 2017. Of these, 80 strains were suspected of producing carbapenemases. The phenotypic test for carbapenemase detection used the disk approximation method with substrates (imipenem and meropenem) and inhibitors (EDTA and ABP) according to the INEI-ANLIS Dr. C. Malbrán recommended algorithm. Results showed 3 (4%) strains positive for carbapenemases. We conclude that the type of carbapenemase found in Pseudomonas aeruginosa was 4%, corresponding to the detection of metallo-beta-lactamases, indicated by the synergistic effect between imipenem and EDTA. No serine carbapenemases were detected.Ítem Acceso abierto Causes of differentiation and rejection in blood donors who went to the National Hospital Guillermo Almenara Irigoyen, Lima, June-July 2019(Universidad Privada Norbert Wiener, 2019-02-20) Córdova Carrión, Giovanna; Cabracancha Gómez, Gladys Janeth; Calderón Cumpa, Luis YuriThe objective of this study was to "Identify the causes of deferral and rejection in blood donors who visited the Hospital Nacional Guillermo Almenara Irigoyen in June - July 2017." The study included all blood donors who visited the blood bank during this period, with a total population of 5,170, of which 1,058 were deferred or rejected. A retrospective, quantitative, basic, cross-sectional, descriptive, non-intervention, and observational study design was used, with a data collection registration form as the instrument. The results were processed using Microsoft Excel, and percentage tables were created. Results: Out of the 5,170 blood donors, 1,058 (20.5%) were deferred or rejected, with 953 (90.07%) deferred and 105 (9.92%) rejected. The main cause for deferral was low hemoglobin at 34.0%, followed by leukocytosis at 16.26%. The main cause of rejection was high-risk sexual behavior, accounting for 72.38% of all rejections, with malaria in second place at 8.57%. Conclusions: The causes of deferral were low hemoglobin, leukocytosis, overstock, and the causes of rejection were high-risk sexual behavior, malaria, and syphilis. The percentage of deferral causes was 18.5%, and rejection was 2.0%. The causes of deferral identified in the study were more prevalent in males, while deferrals due to low hemoglobin were more common in females. The causes of rejection identified in the research predominated in males.Ítem Acceso abierto Characterization of onychomycosis in diabetic patients, Metropolitan Lima 2017-2020.(Universidad Privada Norbert Wiener, 2021-04-30) Jara Bardales, Florentina; Rojas Huaman, Shayli Alejandrina; Navarrete Mejía, Pedro JavierThe global prevalence of onychomycosis was 35.7%, with a higher prevalence in women (73.2%). The average age of the population with diabetes and onychomycosis was 49.9 years, 52.36 years for males and 48.9 years for females. The use of occlusive footwear was present in 77% of those with onychomycosis. In the studied population, 60% of those with onychomycosis lived in overcrowded conditions. 64.7% had unilateral onychomycosis in one foot. The most frequent causative agents were dermatophytes (63.7%) and Candida spp. (36.3%).Ítem Acceso abierto 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 CarlosThis 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.Ítem Acceso abierto Comparative study between ethanol and pisco distillate as cervical cytological fixative(Universidad Privada Norbert Wiener, 2021-09-30) Martínez López, Adita; Paz Alvarez, Miguel Armando; Ascarza Gallegos, Justo AngeloFixation is one of the key components of the pre-analytical phase, ensuring cell preservation and quality in exfoliative cytology tests.

Automated analyzers mark results for a significant proportion of samples and require confirmation through smear review. Therefore, each clinical laboratory needs to verify the reliability of the automated white blood cell differential count (WBC DC) and compare it with the reference method. Objective: To determine if there is a significant difference between the automated white blood cell differential count and the reference method in the Hematology Laboratory of the National Institute of Neoplastic Diseases, 2021. Methods: A prospective cross-sectional study will be conducted at the Hematology Laboratory from October to December 2021. Data will be analyzed using Excel templates, and the following will be performed: (1) For determining the association between two variables with a normal distribution, Pearson correlation will be used, while Spearman’s correlation will be applied if the data does not follow a normal distribution. (2) To compare methods, the standard error of proportion with 95% confidence intervals will be calculated for each cell type. (3) For comparing paired means, statistical significance will be determined using a p-value < 0.05 (Student’s t-test). (4) For analyzing bias (systematic error), the regression equation will be considered.Ítem Acceso abierto Comparison of two methods for the detection of residual antimicrobial activity in urine cultures processed at the National Teaching Hospital Madre Niño San Bartolomé(Universidad Privada Norbert Wiener, 1905-07-07) Rodriguez Vera, Claudia Liliana; Olivo Lopez, Jose MariaObjective: To determine which method, paper diffusion or direct inoculation, detects residual antimicrobial activity more frequently in urine cultures processed at the National Mother-Child Teaching Hospital in San Bartolomé. Materials and Methods: A descriptive, cross-sectional study was conducted from January to March 2014, processing 2024 urine samples from outpatients and hospitalized patients. For both methods to detect residual antimicrobial activity, the samples were inoculated on Muller Hinton agar plates with the Bacillus subtilis ATCC 6633 sensor strain at a 0.5 McFarland scale. In the paper diffusion method, 10 µL of urine was applied on a disk, while in the direct inoculation method, 1 µL of urine was directly inoculated on the agar plate with a sterile loop. Both plates were incubated at 37°C for 24 hours. The presence of an inhibition zone around the disk or direct inoculation point was considered as the presence of residual antimicrobial activity. The absence of an inhibition zone was considered as the absence of residual antimicrobial activity. Results: Residual antimicrobial activity was detected in 9.7% (196/2024) of the urine samples using the paper diffusion method, compared to 6.4% (129/2024) using the direct inoculation method. Moreover, 67 (3.3%) urine samples showed residual antimicrobial activity detected only by the paper diffusion method. In total, 1828 (90.3%) samples showed no residual antimicrobial activity with either method, and 129 (6.4%) showed residual antimicrobial activity. Conclusions: The paper diffusion method has a higher detection rate for residual antimicrobial activity in urine samples processed at the National Mother-Child Teaching Hospital in San Bartolomé.Ítem Acceso abierto Correlation between renal profile and the level of glycosylated hemoglobin in patients with diabetes mellitus treated at María Auxiliadora Hospital, 2017(Universidad Privada Norbert Wiener, 2019-03-14) Bautista Borda, Carlos Daniel; Ucañán Vega, Maria Ximena Natividad; Sandoval Vegas, Miguel HernánTransfusion therapy has helped reduce mortality and improve the quality of life for many cancer patients. The objective of this study was to determine the frequency of transfused blood components in patients with neoplastic diseases registered in the Blood Bank service at the Oncosalud Clinic from June 2016 to June 2018. We conducted a retrospective, descriptive, cross-sectional study. We included patients over 18 years old, with preneoplastic alterations, neoplastic diseases, or with recurrences and treatment control, who had received a full, complication-free transfusion. We included 3,022 transfusion requests, of which 1,525 (50.5%) were women with an average age of 59.8±17.5 years, statistically not significant compared to men (65.3±14.1 years) (p=0.210). Both sexes predominantly required red blood cell concentrate (RBC) at 67.9%, followed by platelets (PLT) at 19.9%. The age group from 56 to 70 years demanded the highest amount of blood products (40.2%). In both periods, hematological neoplasms (49.1%) required the highest number of transfusions, followed by gynecological (16.3%) and gastrointestinal (15.1%) neoplasms. This study demonstrated a high frequency of transfused blood components (red blood cell concentrate and platelets), primarily in hematological neoplasms.Ítem Acceso abierto Cortical Trichological Characterization by Forensic Histotechnology(Universidad Privada Norbert Wiener, 1905-07-09) Torres Zamudio, Susan Melody; Villavicencio Rafael, Andy Anderson; Ascarza Gallegos, Justo AngeloThe forensic importance of the cortex lies in the presence of pigment granules, which will serve as points of comparison for clarifying a criminal act. Therefore, the objective of this study was to characterize cortical trichology using forensic histotechnology. The study was observational, cross-sectional, and exploratory. The sample consisted of 300 samples, evenly divided: 150 human and 150 animal samples. Cross-sections were performed for analysis. The statistical analysis was done using contingency tables in SPSS. Five criteria were considered in the microscopic evaluation: Pigment Size (pigment granules in human cortex were fine, whereas in animals, they were coarse), Pigment Distribution (pigment granules in humans were peripheral, and in animals, central), Cortical Substance (the cortical substance in humans formed a thick cuff, while in animals, it was a hollow cylinder), Tonality (dark-toned pigments were granular, brownish pigments were diffuse, and grayish tones had no pigment), and Region of Origin (head hair was circular/oval with a narrow and central medulla, while pubic hair had an elliptical/irregular shape with an eccentric medulla). It is concluded that it is possible to characterize trichology based on pigment size, pigment distribution, cortical substance, tonality, and region of origin using the cortex and its elements.Ítem Acceso abierto Cyto-histological correlation of cervical intraepithelial lesions at the Hospital San José del Callao 2016-2019(Universidad Privada Norbert Wiener, 2020-10-01) Rodríguez Canayo, Janice; Rosas Marroquin, Nancy PilarCervical cancer (CCU) represents a public health issue for Peru due to its high morbidity and mortality rates, resulting in many years of healthy life lost. This cancer has a pre-neoplastic stage, detected by cytology.Ítem Acceso abierto Cytological Alterations of the Cervix in Patients at a Public Hospital in Lima from March to September 2016(Universidad Privada Norbert Wiener, 1905-07-09) Aguilar Félix, Liliana; Espinoza Calero, Julio CesarObjective: To determine cytological alterations of the cervix in patients at a public hospital in Lima from March to September 2016. Materials and Methods: A retrospective, descriptive, cross-sectional study was conducted in 4,535 patients who underwent Papanicolaou tests in the Gynecology and Obstetrics Department of a public hospital in Lima Metropolitan Area, from March to September 2016. Papanicolaou reports and cytological study request forms were used to collect the data, which were recorded in a data collection form. Results: The rate of cytological alterations was 2.9%, with 50.4% presenting ASC-US, 4.6% ASC-H, 25.2% low-grade squamous intraepithelial lesion, and 19.8% high-grade squamous intraepithelial lesion. The most represented age group among those with cytological alterations was middle-aged women (45-64 years) with 45.8%. No cytological alterations were found in the adolescent group. Conclusions: The rate of cervical cytological alterations in patients at a public hospital in Lima from March to September 2016 was 2.9%, highlighting the need for continued control measures.Ítem Acceso abierto Cytological and histological correlation in the diagnosis of intraepithelial lesions of the cervix in Patients at San Juan de Lurigancho Hospital 2010 – 2013(Universidad Privada Norbert Wiener, 1905-07-07) Sánchez Del Pozo, Olinda; Suárez Espino, Martha; Osorio Prado, Jesús IvánTo determine the correlation between cytology and histology in the diagnosis of cervical intraepithelial lesions in patients at the San Juan de Lurigancho Hospital from 2010 to 2013. Study Type: Descriptive, retrospective, non-experimental. Findings: Between 2010 and 2013, 5732 cervical-vaginal cytological reports from women aged 21 to 79 were reviewed. Of these, 97.2% were reported as negative for intraepithelial lesions. A total of 110 patients underwent cervical biopsy. Results: The average age of women diagnosed with LIEBG and LIEAG via Pap smear was 45 and 44.2, respectively. Sensitivity, specificity, positive predictive value, and negative predictive value were 66.67%, 65.7%, 80.6%, and 47.9%, respectively. The cytological-histological discrepancy was 33% (37/110). The correlation for low-grade lesions was 78.3% (29/37). There was under-diagnosis in 7.1% (3/42) of cases that turned out to be LIEAG and 2.3% (1/42) that were malignant neoplasms. Over-diagnosis occurred in 21.4% (9/42) where lesions were negative for intraepithelial lesions or malignant neoplasms. The correlation for high-grade lesions was 72.7% (8/11). No under-diagnosis occurred (cases that would have been malignant invasive neoplasms). Over-diagnosis occurred in 57% (11/19), as they were classified as LIEBG 42% (8/19) or negative for lesions or malignant neoplasms 15% (3/19). Conclusions: The study rejects the hypothesis of no correlation between cytology and histology in the diagnosis of cervical intraepithelial lesions.Ítem Acceso abierto Cytological and histological relationship in the diagnosis of high-grade squamous intraepithelial lesions of the cervix in patients at the National Hospital Arzobispo Loayza, 2016-2017(Universidad Privada Norbert Wiener, 2019-02-20) Palpa Gómez, Jesica Yesenia; Arias Guzmán, Evelyn Ruth; Rosas Marroquin, Nancy PilarThe objective is to determine the relationship between Cytology and Histology in the diagnosis of high-grade squamous intraepithelial lesion of the cervix in patients at the Hospital Nacional Arzobispo Loayza from 2016 to 2017. A search for theoretical information was conducted on reliable websites such as Medigraphic, Medic Books, and repositories. This is a quantitative, correlational, cross-sectional, and retrospective study; 50 patients with a cytological result of high-grade squamous intraepithelial lesion were analyzed, which was later complemented with a histological study in the Pathology Laboratory at the Hospital Nacional Arzobispo Loayza between 2016 and 2017. Chi-square contingency tables were used to examine the relationship between Cytology and Histology, where a P value of < 0.05 (0.000) and a 95% confidence level were obtained, indicating a significant relationship. Consequently, the hypothesis was accepted, and the Kappa index was also analyzed, which qualitatively expresses the "Strength of agreement," showing poor agreement. Based on the study, it was concluded that the Cytological test had a poor correlation with the Histological test for diagnosing high-grade squamous intraepithelial lesion of the cervix in patients at the Hospital Nacional Arzobispo Loayza.Ítem Acceso abierto Degree of accuracy and precision level of the most used Glucometers in Metropolitan Lima, 2015(Universidad Privada Norbert Wiener, 1905-07-07) Talaverano Llactas, Luis Hover; Sandoval Vegas, Miguel HernánThe Glucotest is a device for measuring blood glucose levels using electrochemical methods or photometric reflectance, available in different brands, designs, and applications for monitoring and treating diabetes. The objective was to determine the accuracy and precision of the most commonly used Glucotests in Metropolitan Lima in 2015, through a quantitative, technological, prospective, cross-sectional, descriptive, and correlational study. Three brands of devices were studied: Prestige Easy, Onetouch Ultra Mini, and Accu-Chek Active. Results were compared with laboratory results under internal and external quality control. Accuracy (E%), precision (CV%), and correlation were assessed using Pearson’s r. Results showed that Prestige Easy had an E% of 12.12% and CV% ranging from 4.53% to 4.89%, outside the desired range. Onetouch Ultra Mini had an average E% of 9.1%, with acceptable CV% values of 1.50% and 1.58% in levels I and II, and a CV% of 2.68% in level III. Accu-Chek Active had an E% of 6.17%, with acceptable CV% values of 1.50% and 1.58%, and a CV% of 2.68% in level III. Correlation coefficients were: Prestige Easy 0.77, Onetouch Ultra Mini 0.90, and Accu-Chek Active 0.96. In conclusion, the Glucotest Accu-Chek showed better accuracy compared to Prestige Easy or Onetouch Ultra Mini, although only 30% of values were accurate. Only the Accu-Chek Glucotest showed adequate precision quality at all three glucose levels studied, while the Prestige Easy test had lower precision. In general, precision was better than accuracy across all devices, but none met the ideal limits.Ítem Acceso abierto Description of the activity of the CKMB isoenzyme in vitreous humor in corpses with suspected acute myocardial infarction from the Institute of Legal Medicine.(Universidad Privada Norbert Wiener, 2020-07-23) Oblitas Falero, Yesenia Elizabeth; Ascarza Gallegos, Justo AngeloForensic sciences make the final diagnosis of cause of death with the help of auxiliary tests, such as CKMB. One of the biological samples used in forensics is vitreous humor due to its high protection against cellular lysis. To describe the activity of the CKMB isoenzyme in vitreous humor in corpses suspected of acute myocardial infarction, 23 vitreous humor samples were collected from suspicious corpses at the Callao Institute of Forensic Medicine and analyzed using the CKMB reagent on the BT3000 plus biochemical analyzer. The mode, median, average, standard deviation, percentiles, kurtosis, and skewness were evaluated, with the gold standard being the anatomopathological result. The descriptive statistics of male corpses showed a higher result than females, with a normal and symmetric distribution. The lowest biochemical CKMB result was 6 U/L, and the maximum was 7386 U/L. The anatomopathological diagnosis confirmed acute myocardial infarction. The dispersed CKMB values in vitreous humor samples from corpses did not show an adequate marker for acute myocardial infarction.Ítem Acceso abierto Design of procalcitonin versus markers used for the diagnosis of bacterial sepsis in patients at the Intensive Care Unit of the National Hospital Alberto Sabogal Sologuren, 2015(Universidad Privada Norbert Wiener, 1905-07-07) Gonzales Vasquez, Jose Marino; Hilario Velasquez, Flor Eduvines; Baltodano Honores, Carlos AlbertoIntroduction: Diagnosing sepsis in the Intensive Care Unit remains a major challenge, as it can lead to death due to multiple organ failure. Procalcitonin is a marker used to differentiate bacterial infections from inflammatory processes of other etiologies. The aim of this study was to determine the performance of procalcitonin compared to other markers used to diagnose bacterial sepsis in the Intensive Care Unit of the National Alberto Sabogal Sologuren Hospital in 2015. Methodology: The study was descriptive, comparative, non-experimental, prospective, and cross-sectional. Results: 30 patients from the Intensive Care Unit of the National Alberto Sabogal Sologuren Hospital, with a presumptive diagnosis of sepsis, were studied from January to April 2015. Of these, 26.67% had a positive blood culture, considered the confirmatory test for bacterial sepsis. The performance of the tests was as follows: Procalcitonin (PCT): Sensitivity (S) 87.5%, Specificity (E) 95.45%, Positive Predictive Value (PPV) 87.5%, Negative Predictive Value (NPV) 95.4%. For C-reactive protein (CRP): S 100%, E 0%, PPV 26%, NPV 0%. For the Erythrocyte Sedimentation Rate (ESR): S 100%, E 4.76%, PPV 27.58%, NPV 100%. For white blood cell count: S 75%, E 50%, PPV 35.2%, NPV 84.6%. For neutrophil percentage: S 100%, E 15.78%, PPV 29.63%, NPV 100%. Conclusion: Procalcitonin showed better performance for diagnosing bacterial sepsis compared to other markers used currently in the hospital.
