Establece un protocolo de validación dirigido a la estandarización, optimización y validación de una prueba de PCR convencional para el diagnóstico confirmatorio del HTLV-1 en PBMCs. Las pruebas de reacción en cadena de la polimerasa convencional (PCR) o en tiempo real de tipo cuantitativa (qPCR) son propuestas debido a su versatilidad a materiales biológicos, alta sensibilidad y especificidad y relativo bajo costo. La detección del provirus del HTLV-1 por pruebas de PCR convencional tiene bajo costo y es aplicable a diversos formatos como placas de 96 pozos, tiras de 8 pozos y tubos individuales. En contraparte, las pruebas de qPCR generalmente usan master mix universales que limitan las oportunidades de optimización y requiere del uso de una placa de reacción de 96 pozos para el procesamiento de 16 muestras. Por tanto, se desarrolla una prueba de PCR convencional priorizando ...

Background: Sputum smear microscopy (SSM) is a screening test used to diagnose tuberculosis (TB); however, its performance and sensitivity are relatively low, which can lead to false negatives. We designed a cross-sectional study to estimate the performance of SSM that includes a pretreatment based on sputum digestion with bleach (sodium hypochlorite) for the diagnosis of TB. Methods: We evaluated 73 sputum samples from patients with a diagnosis of TB confirmed by the Xpert MTB/RIF test and 114 samples from patients without TB. We performed sputum digestion using a 5% sodium hypochlorite solution, centrifuged at 2000 rpm for 15 min. We prepared smears for direct and bleach-treated SSM and used Ziehl–Neelsen staining. Results: The bleach-treated SSM obtained absolute identification of the cases of TB confirmed by the Xpert test, compared to 95.9% identified by the direct smear method (w...

Objetive: Evaluate an Ozone Generating System (OGS) through of the microorganisms count and identificated in the air of the sanitary environments of the National Institute of Health (INS) from Peru. The study: These were exposed to OGS for 1 min per m2, air samples were collected at volumes of 200L, 500L and 1000L by impaction, pre and post exposure to OGS, cultures were obtained on Plate Count Agar (PCA) and Oxytetracycline Glucose Agar (OGA) grown at 35°C±2°C for 48 hours and 25°C ± 2°C for 5 days. Findings: A decrease in the count of fungi after exposure to OGS, the difference being statistically significant for the volumes of 200L (p=0.047) and 1000 L (p<0.005); Aspergillus spp. species were identified in most cultures, in bacteria no significant difference was observed. Conclusions: The OGS is a method that inhibits the growth of most fungi in sanitary environments.

Introducción: Las complicaciones por diabetes tipo 2 (DT2) están incrementando la demanda de servicios especializados en la Seguridad Social Peruana por lo que se torna necesario determinar la magnitud y factores asociados a complicación crónica por DT2 en esta población. Material y Métodos: Estudio transversal-analítico basado en 7875 registros de pacientes con DT2 ≥ 18 años atendidos por consulta externa durante 2016-2017 y notificados en el Sistema de Vigilancia de Diabetes Mellitus de EsSalud. Se evaluaron variables sociodemográficas, clínicas y de comorbilidad mediante un análisis bivariado y un modelo de regresión de Poisson con varianza robusta para determinar la razón de prevalencia a complicación crónica por DT2. Resultados: La complicación microvascular de DT2 estuvo asociado a sexo masculino (RP=1,25; 95%IC: 1,10-1,42; p<0,01), HbA1c>9,0% (RP=1,25; 95%IC: 1,0...

Background: Type 2 diabetes (DT2) complications has been increased the demand for specialized services in Peruvian Social Security(EsSalud), so it is necessary to determine the magnitude and factors associated with chronic complication due to DT2 in this population. Material and Methods: Cross-sectional study based on 7875 patients with DT2≥18 years attended by ambulatory care during 2016-2017, notified in the Diabetes Mellitus Surveillance System of EsSalud. Sociodemographic, clinical and comorbidity variables were evaluated using a bivariate analysis and Poisson regression model with robust variance to determine the prevalence ratio of chronic complication due to DT2. Results: The microvascular complication of DT2 was associated with male sex (PR=1.25; 95% CI:1.10-1.42; p<0.01), HbA1c>9.0% (PR=1.25; 95% CI:1.08-1.46; p<0.01), hypertension (PR=1.30; 95% CI: 1.14-1.49; p<0....

Peru is one of the countries with the highest leadcontamination in the world. Biological monitoring has lim-itations due to the shortage of laboratories with validatedmethodologies for the measurement of blood lead, and it isnecessary to use alternative methods for its measurement inhigh-altitude cities. We aimed to compare the blood leadlevels (BLL) measured by the LeadCare II (LC) method andGraphite Furnace Atomic Absorption Spectrometry (GF-AAS). We measured the BLL of 108 children from the city ofLa Oroya. The mean and median BLL for GF-AAS were10.77±4.18 and 10.44lg/dL, respectively; for the LCmethod, the mean was 11.71±4.28 and the median was11.60lg/dL. We found a positive linear correlation(Rho = 0.923) between both methods. Notwithstanding, theWilcoxon test suggests a significant difference between bothmethods (q= 0.000). In addition, the Bland–Altmananalysis indicates that t...

“Peru is one of the countries with the highest lead contamination in the world. Biological monitoring has limitations due to the shortage of laboratories with validated methodologies for the measurement of blood lead, and it is necessary to use alternative methods for its measurement in high-altitude cities. We aimed to compare the blood lead levels (BLL) measured by the LeadCare II (LC) method and Graphite Furnace Atomic Absorption Spectrometry (GFAAS).

Introduction. The chronic complications of type-2-diabetes mellitus (T2DM) increase mortality and burden of disease in Peru, then it is necessary to evaluate its prevalence and associated factors. Methods. Cross-sectional study in records of 212 adult outpatients with T2DM attended by a social security general hospital in Peru, during 2017. Results. 71,6% of patients were older than 60 years and with a time of illness less than 6 years (40,5%). 38,7% of the patients had any chronic complication, mainly nephropathy (48,8%) and neuropathy (45,1%). Hypertension (52,4%) and obesity (43,7%) were the most frequent comorbidities in outpatients with chronic complications. Complications from DMT2 were associated with the medical consultations and glycemic monitoring. Conclusions. There are risk factors associated to chronic complications of DMT2.
