Background Estimating the cumulative prevalence of SARS-COV-2 will help to understand the epidemic, contagion, and immunity to COVID-19 in vulnerable populations. The objective is to determine the extent of infection in the general population and the cumulative incidence by age group. Methods It was carried out with a longitudinal analytical study, in the population of the Lambayeque region, located in the north of Peru. The selection was carried out in multistages (districts, area, household, and finally choosing the interviewee within the house). Seroprevalence was estimated as a positive result of the rapid test whether it was positive IgM or positive IgG. An adjustment was made for the sampling weights used. Results The seroprevalence found in the region was 29.5%. Young people between 21 and 50 years old presented the highest seroprevalence frequencies. A total of 25.4% were asymptomatic. The most frequent complaint was dysgeusia and dysosmia (85.3% and 83.6%). Dysosmia (PR = 1.69), chest pain (PR = 1.49), back pain (PR = 1.45), cough (PR = 1.44), fever (PR = 1.41), general malaise (PR = 1.27) were associated factors with the higher the frequency of seropositivity for SARS-CoV-2. Reporting of complete isolation at home decreased the frequency of positivity (PR = 0.80), however, reporting having ARI contact (PR = 1.60), having contact with a confirmed case (PR = 1.51), and going to market (PR = 1.26) increased the frequency of positivity for SARS-CoV-2. Conclusion These results suggest that Lambayeque is the region with the highest seroprevalence in the world, well above Spain, the United States and similar to a study in India.
Introducción: El presente artículo resume la guía de práctica clínica (GPC) para el diagnóstico y manejo de los pacientes con colelitiasis, colecistitis aguda y coledocolitiasis en el Seguro Social del Perú (EsSalud). Objetivo: Proveer recomendaciones clínicas basadas en evidencia para la evaluación y el manejo de pacientes con colelitiasis, colecistitis aguda y coledocolitiasis en EsSalud. Métodos: Se conformó un grupo elaborador de la guía (GEG) que incluyó médicos especialistas en gastroenterología, cirujanos generales y metodólogos. El GEG formuló 10 preguntas clínicas a ser respondidas por la presente GPC. En septiembre del 2017 se realizaron búsquedas de revisiones sistemáticas y –cuando fue considerado pertinente– estudios primarios en PubMed. Se seleccionó la evidencia para responder 10 preguntas clínicas. La certeza de la evidencia fue evaluada usando la metodología Grading of Recommendations Assessment, Development, and Evaluation (GRADE). En reuniones de trabajo periódicas, el GEG usó la metodología GRADE para revisar la evidencia y formular las recomendaciones, los puntos de buenas prácticas clínicas y el flujograma de evaluación y manejo. Finalmente, la GPC fue aprobada con Resolución N° 021-IETSI- ESSALUD-2018. Resultados: La presente GPC abordó 10 preguntas clínicas sobre el diagnóstico y manejo de colelitiasis, colecistitis aguda y coledocolitiasis. En base a dichas preguntas se formularon 6 recomendaciones (5 recomendaciones condicionales y 1 recomendación fuerte), 17 puntos de buena práctica clínica y 3 flujogramas. Conclusión: El presente artículo resume la metodología y las conclusiones de la l diagnóstico y tratamiento de la colelitiasis, colecistitis aguda y coledocolitiasis de EsSalud.
Positron emission tomography (PET) has been used to aid in diagnosis of inflammatory and infectious disease. We describe the case of a patient with early-latent syphilis with increased metabolic activity along the aorta detected via PET, suggesting probable aortitis. Three-months following treatment, the PET showed apparent resolution of the aortitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
