Producción científica peruana sobre resistencia a los antimicrobianos de bacterias priorizadas por la OMS / Peruvian scientific production on antimicrobial-resistant bacteria prioritized by WHO

Introducción: La resistencia a los antimicrobianos (RAM) es una crisis de salud pública a nivel mundial. La Organización Mundial de la Salud (OMS) estableció una lista de bacterias resistentes priorizadas para orientar investigaciones y alternativas de mejora. Objetivo: Describir la producción científica del Perú sobre RAM de bacterias priorizadas por la Organización Mundial de la Salud, entre 2012 y 2021. Métodos: Estudio descriptivo observacional de tipo bibliométrico en revistas indexadas en Scopus durante el período 2012-2021. La selección de los estudios y la extracción de datos se realizó manualmente por duplicado. Se clasificaron las bacterias resistentes estudiadas, según las prioridades (crítica, alta y media). Resultados: Se incluyeron 118 artículos. Durante el período 2014-2021 hubo un aumento de publicaciones. El 61,9 por ciento fueron artículos publicados en inglés, 98,3 por ciento con filiación en Perú y el 77,1 por ciento fueron realizados en Lima. Se publicaron más estudios sobre las bacterias de prioridad crítica que sobre las de alta o media. El 79,7 por ciento buscó determinar la prevalencia o caracterizar y el 26,1 por ciento mencionó algún financiamiento de instituciones del país. Conclusión: La producción científica peruana sobre RAM ha aumentado en los últimos años y se cuenta con más publicaciones de bacterias de prioridad crítica. Sin embargo, estos estudios se centran en Lima y solo la cuarta parte ha sido financiada por alguna entidad peruana(AU)

Introduction: Antimicrobial resistance (AMR) is a worldwide public health crisis. The World Health Organization (WHO) established a priority list of resistant bacteria to guide research and alternatives for improvement. Objective: To describe the scientific production of Peru on AMR of bacteria prioritized by the World Health Organization, between 2012 and 2021. Methods: Observational descriptive study of bibliometric type in journals indexed in Scopus during the period 2012-2021. The selection of studies and data extraction were performed manually in duplicate. Resistant bacteria studied were classified based on priority (critical, high, and medium). Results: A total of 118 articles were included. During the period 2014-2021, the number of publications increased. The articles published in English accounted for 61.9 percent, 98.3 percent had their affiliation in Peru, and 77.1 percent were conducted in Lima. Most publications focused on bacteria of critical priority than high and medium priority. A total of 79.7 percent sought to determine prevalence or characterize and 26.1 percent referred to funding from Peruvian institutions. Conclusions: Peruvian scientific production on AMR has increased in recent years and there are more publications on critical priority bacteria. However, these studies are centered in Lima and only a quarter of them have been financed by a Peruvian entity(AU)

Immune reconstitution inflammatory syndrome associated with secondary syphilis: dermatologic, neurologic and ophthalmologic compromise in an HIV patient.

The presentation of syphilis as a manifestation of immune reconstitution inflammatory syndrome in patients with human immunodeficiency virus (HIV) infection is rare and can be associated with the varied clinical expression of unusual syphilitic manifestations. We report a case of immune reconstitution syndrome with dermatologic, ophthalmologic and neurologic compromise of secondary syphilis in a patient with HIV infection.

Latent tuberculosis infection is associated with increased unstimulated levels of interferon-gamma in Lima, Peru.

BACKGROUND: We previously reported increased unstimulated blood levels of interferon-gamma in persons with latent tuberculosis infection (LTBI) in the United States, suggesting enhanced immune activation in LTBI. To investigate this further in a TB-endemic setting, we assessed interferon-gamma levels in persons with and without LTBI in Peru. METHODS: We analyzed data from patients with and without a recent type 1 (spontaneous) acute myocardial infarction (AMI) who were enrolled from two public hospital networks in Lima, Peru, and underwent LTBI testing using the QuantiFERON® TB Gold In-tube (QFT) assay. Participants with a positive QFT test were defined as having LTBI, whereas participants with a negative QFT test were defined as non-LTBI. Unstimulated interferon-gamma was quantified via enzyme-linked immunosorbent assay in the QFT nil-tube, which does not contain antigens. We compared unstimulated interferon-gamma levels between LTBI and non-LTBI groups using the Wilcoxon rank sum test. We used proportional odds modeling for multivariable analysis. RESULTS: Data from 214 participants were included in this analysis. Of those, 120 (56%) had LTBI. There were no significant differences in age, sex and comorbidities between LTBI and non-LTBI participants, except for recent AMI that was more frequent in LTBI. LTBI participants had higher unstimulated interferon-gamma levels compared to non-LTBI participants (median, interquartile range; 14 pg/mL, 6.5-52.8 vs. 6.5 pg/mL, 4.5-15; P<0.01). LTBI remained associated with higher unstimulated interferon-gamma levels after controlling for age, sex, recent AMI, history of hypertension, diabetes mellitus, dyslipidemia, end stage renal disease, malignancy, obesity, and tobacco use (adjusted odds ratio, 2.93; 95% confidence interval, 1.8-4.9). In a sensitivity analysis that excluded participants with AMI, the association between unstimulated interferon-gamma and LTBI remained present (adjusted odds ratio; 3.93; 95% confidence interval, 1.9-8.2). CONCLUSIONS: LTBI was associated with higher unstimulated interferon-gamma levels. These data suggest ongoing immune activation in LTBI.

[Educational environment in a Peruvian medical school. A negative trend over the academic years]. / Ambiente educativo en una facultad de medicina peruana: una tendencia negativa a lo largo de los años académicos.

BACKGROUND: Educational environment refers to the material resources and interpersonal relationships of an educational institution. AIM: To describe the educational environment of a Peruvian medical school and to explore a possible association between curricular years and the educational environment. MATERIAL AND METHODS: A cross-sectional study was conducted using the Dundee Ready Education Environment Measure (DREEM) to evaluate the educational environment of a Peruvian medical school. Data collection consisted in online surveys completed voluntarily by 1st through 6th year medical students between April and October 2015. RESULTS: The questionnaire was completed by 828 of 2,421 (34.2%) students. The mean DREEM score was 117 ± 25.6 of a maximum of 200. A poorer perception of the educational environment was associated with later years in the curriculum, when analysis was adjusted for gender, age and academic status (p < 0.001). CONCLUSIONS: The educational environment of this medical school scored positively (> 100 points). However, it was evident that medical students in later curricular years had a more negative perception of the educational environment compared to those in earlier academic years.

The Relationship Between Latent Tuberculosis Infection and Acute Myocardial Infarction.

Background: Tuberculosis has been associated with an increased risk of cardiovascular disease (CVD), including acute myocardial infarction (AMI). We investigated whether latent tuberculosis infection (LTBI) is associated with AMI. Methods: We conducted a case-control study in 2 large national public hospital networks in Lima, Peru, between July 2015 and March 2017. Case patients were patients with a first time diagnosis of type 1 (spontaneous) AMI. Controls were patients without a history of AMI. We excluded patients with known human immunodeficiency virus infection, tuberculosis disease, or prior LTBI treatment. We used the QuantiFERON-TB Gold In-Tube assay to identify LTBI. We used logistic regression modeling to estimate the odds ratio (OR) of LTBI in AMI case patients versus non-AMI controls. Results: We enrolled 105 AMI case patients and 110 non-AMI controls during the study period. Overall, the median age was 62 years (interquartile range, 56-70 years); 69% of patients were male; 64% had hypertension, 40% dyslipidemia, and 39% diabetes mellitus; 30% used tobacco; and 24% were obese. AMI case patients were more likely than controls to be male (80% vs 59%; P < .01) and tobacco users (41% vs 20%; P < .01). LTBI was more frequent in AMI case patients than in controls (64% vs 49% [P = .03]; OR, 1.86; 95% confidence interval [CI], 1.08-3.22). After adjustment for age, sex, hypertension, dyslipidemia, diabetes mellitus, tobacco use, obesity, and family history of coronary artery disease, LTBI remained independently associated with AMI (adjusted OR, 1.90; 95% CI, 1.05-3.45). Conclusions: LTBI was independently associated with AMI. Our results suggest a potentially important role of LTBI in CVD.

[High frequency of dyslipidemia in VIH-infected patients in aa peruvian public hospital]. / Elevada frecuencia disclipidemia en pacientes infectados por VIH en un Hospital público peruano.

The objective of the study was to determine the frequency and characteristics of dyslipidemia in patients with HIV in highly active antiretroviral therapy (HAART) in a Peruvian public hospital. A cross-sectional study was carried out in patients with complete lipid profile after receiving at least six months of HAART. Dyslipidemia was defined according to the criteria of the NCEP-ATP III. We reviewed 2 975 clinical histories, and included 538 (18.1%) in the analysis. The frequency of dyslipidemia was 74.7%. HAART regimens which include protease inhibitors (PI) (odds ratio [OR]: 1.22; confidence interval at 95% [CI 95%]: 1.11-1.33) and to be older than 40 years (OR: 1.17; CI 95%: 1.05-1.28) were associated with dyslipidemia, adjusted by viral load, CD4 lymphocyte level and gender. In conclusion, dyslipidemia was very common in our sample and was mainly associated with the use of PI. It is necessary to promote the dyslipidemia control as part of the comprehensive care of the patient with HIV.

El objetivo del estudio fue determinar la frecuencia y características de la dislipidemia en pacientes con VIH en terapia antirretroviral de gran actividad (TARGA) en un hospital público peruano. Se realizó un estudio transversal en pacientes que tuvieran un perfil lipídico completo luego de recibir al menos seis meses de TARGA. La dislipidemia se definió según los criterios NCEP-ATP III. Se revisaron 2975 historias clínicas, 538 (18.1%) fueron incluidas en el análisis. La frecuencia de dislipidemia fue 74.7%. Los esquemas de TARGA que incluían inhibidores de la proteasa (IP) (OR 1.22; IC95% 1,11-1,34) y la edad mayor de 40 años (OR 1.17; IC95% 1,06-1,29) mostraron asociación con dislipidemia, ajustado por carga viral, nivel de células CD4 y sexo. En conclusión, la dislipidemia fue muy frecuente en la muestra estudiada y estuvo asociada principalmente al uso de IP. Es necesario promover el control de la dislipidemia como parte de la atención integral del paciente con infección por VIH.

[Psychometric analysis of a questionnaire to measure the educational environment in a sample of medical students in Peru]. / Análisis psicométrico de un cuestionario para medir el ambiente educativo en una muestra de estudiantes de medicina en Perú.

The objective of the study was to determine the psychometric properties of the Dundee Ready Education Environment Measure (DREEM) questionnaire in students of a Peruvian medical school. Participants were first-to-sixth-year students, invited to participate through a web platform. In the analysis the alpha coefficient of Cronbach was used to evaluate internal consistency. In addition, a confirmatory factorial analysis was performed to evaluate the construct validity of the subscales of the DREEM. The adjustment quality indexes used were: Root Mean Square Error Approximation (RMSEA), the Index of Benchmarking (CFI), Tucker-Lewis Index (TLI), and the Standardized Root Mean Residual (SRMR). The results showed that the social self-perception dimension had an alpha of Cronbach of less than 0.70. In addition, the quality indices did not support the five-dimensional structure of the DREEM. In conclusion, the DREEM questionnaire did not perform optimally in this Peruvian sample.

El objetivo del estudio fue determinar las propiedades psicométricas del cuestionario Dundee Ready Education Environment Measure (DREEM) en estudiantes de una facultad de Medicina peruana. Los participantes fueron los alumnos de primero a sexto año, invitados a participar mediante una plataforma web. En el análisis se utilizó el coeficiente alfa de Cronbach para evaluar consistencia interna. Además, se realizó un análisis factorial confirmatorio para evaluar la validez de constructo de las subescalas del DREEM. Los índices de bondad de ajuste utilizados fueron: error cuadrático medio de aproximación (RMSEA), el índice de ajuste comparativo (CFI), índice Tucker-Lewis (TLI) y el residuo estandarizado cuadrático medio (SRMR). Los resultados mostraron que la dimensión Autopercepción Social tuvo un alfa de Cronbach menor a 0,70. Además, los índices de bondad no apoyaron la estructura de cinco dimensiones del DREEM. Como conclusión, el cuestionario DREEM no tuvo un desempeño óptimo en esta muestra peruana.
