Transfusion 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.

The 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.

Influence of the time and angle of inclination of the centrifuged tube during the decantation process on the leukocyte count of the urinary sediment
(Universidad Privada Norbert Wiener, 2020-02-26) Gallegos Galván, Elizabeth; Ortiz Gómez, María Elizabeth; Sandoval Vegas, Miguel Hernán
Urinalysis is the second most common laboratory test, and its proper performance during the process, especially in the evaluation of urinary sediment, is essential. The goal of our study was to determine the influence of the time and angle of inclination of the centrifuge tube during the decantation process on the leukocyte count in urinary sediment. A descriptive, cross-sectional, prospective experimental study was conducted, collecting 100 urine samples from patients at a private clinic in northern Lima. All samples met the inclusion criteria and quality control standards, and the leukocyte counts were evaluated according to the Clinical Laboratory Standards Institute (CLSI) GP16-A3 protocol. From the total samples, 89% were women. The frequency of cases with or without variation in the leukocyte count, at decantation angles of 135º and 180º and times of 2 and 1 seconds, showed that 12% and 23% had the same count (p=0.040). A significant influence of the time and angle of inclination of the centrifuge tube during decantation on the leukocyte count in the urinary sediment was determined.

Laboratory results of coronary risk and its relationship with biochemical indicators in hepatic clinical histories at the National Perinatal National Institute from December 2016 to July 2018
(Universidad Privada Norbert Wiener, 2019-08-01) Reyes Moreno, Gustavo Andre; Sandoval Vegas, Miguel Hernán
The studied biochemical liver indicators include Glutamic-Pyruvic Transaminase (GPT), Glutamic-Oxaloacetic Transaminase (GOT), total proteins, and albumin, which are commonly used to give a prognosis of liver damage in a person. The objective of this work was to evaluate the relationship between laboratory results for coronary risk and biochemical liver indicators in medical records of patients over 18 years of age at the National Maternal Perinatal Institute, from December 2016 to July 2018, through a descriptive cross-sectional study. Both variables were related using the percentage of cardiovascular disease (CVD) risk with the help of the Framingham table by category, dividing medical records into risk percentage groups of 1%, 2%, 3%, 4%, 5%, and 6% and above, showing that 13.5% of the studied population had moderate risk. High levels of triglycerides were found to be related to the coronary risk group, as well as total cholesterol, HDL cholesterol, and LDL cholesterol. However, when comparing biochemical liver indicators with the CVD risk level, GOT levels did not show a significant statistical relationship, nor did GPT and albumin. Consequently, there was no relationship found between coronary risk laboratory results and biochemical liver indicators.

(Universidad Privada Norbert Wiener, 2019-08-01) Ramirez Suarez, Klaus Ali Bey; Sandoval Vegas, Miguel Hernán
Urine analysis is the first and most important laboratory test in evaluating a patient with suspected kidney disease, providing valuable data. Examination of urinary sediment is especially useful for diagnosing urinary tract infections, particularly when detecting asymptomatic bacteriuria, and can also be done using the Neubauer chamber for leukocyte counts. Objective: To determine the relationship between leukocyte counts obtained by the sedimentation method and the Neubauer chamber method in urine samples collected at the Instituto Materno Perinatal (INMP) Clinical Laboratory in Lima in 2017. Materials and Methods: A selection of 68 urine samples from pregnant women was made. This is a quantitative, correlational, and prospective study, using the Pearson correlation test to analyze the relationship between leukocyte counts from sediment and the Neubauer chamber method. Results: A correlation value of 0.730 was found between the sedimentation method and the Neubauer chamber method. The Neubauer chamber achieved 100% sensitivity, 32.6% specificity, 46.3% positive predictive value, 100% negative predictive value, and 57% diagnostic certainty, with positive and negative likelihood ratios of 1.48 and 0, respectively. Conclusion: A good correlation was found between the sedimentation method and the Neubauer chamber method for identifying leukocytes, demonstrating that despite a good correlation, the Neubauer chamber does not apply as a diagnostic test.

This study included 166 pregnant women who underwent a 75g OGTT (Oral Glucose Tolerance Test) from August 2017 to June 2018. The prevalence of gestational diabetes was determined using three diagnostic criteria: the IADPSG was 29.5%, the ADA 24.5%, and the WHO 11.5%. It was observed that the ADA criteria had a sensitivity (S) of 83%, a specificity (E) of 100%, a positive predictive value (PPV) of 100%, and a negative predictive value (NPV) of 93%. The incidence rate (IR) was 95%, and the Youden Index (YI) was 0.8. When comparing the WHO criteria, the sensitivity was 32%, specificity was 97%, PPV was 84%, and NPV was 77%. The IR was 78%, and the YI was 0.3. It was observed that older age in pregnant women was associated with higher prevalence of gestational diabetes. The study concluded that significant differences exist in the prevalence of gestational diabetes when using different diagnostic criteria, with the IADPSG criteria showing the highest sensitivity and specificity, followed by the ADA criteria with acceptable indices, while the WHO criteria showed critical values for detecting gestational diabetes.

Proteinuria by the method of sulfosalicylic acid and its relationship with glomerular filtration calculated by several formulas in pregnant women at a Maternity Hospital in Lima, 2017
(Universidad Privada Norbert Wiener, 2018-10-10) Ruiz Yarlequé, Patricia; Bazán Estrella, Kateryn Nataly; Sandoval Vegas, Miguel Hernán
The objective was to determine the relationship between proteinuria by the sulfosalicylic acid method and glomerular filtration rate (GFR) calculated by several formulas in pregnant women at a maternity hospital in Lima in 2017. This is an applied, observational, retrospective, descriptive, and correlational study. A total of 244 results meeting the selection criteria were collected. Of these, 64% presented proteinuria by the sulfosalicylic acid method, 5.7% had traces, and 30.3% were negative. Using different GFR formulas, the proteinuria results were correlated, and no relationship was found between the study variables (ANOVA, p > 0.05). Therefore, this method is not a useful tool when a test is needed to accurately identify renal function in pregnant women. For a better study of this test and comparison with GFR formulas, it is recommended to conduct a study with absorbance readings of the test (ASS), which would provide a quantitative result and greatly assist in the diagnosis of renal function.
