ABSTRACT
Introducción: el nivel socioeconómico (NSE) de las familias tiene un papel fundamentan en el desempeño académico de los estudiantes. Durante la pandemia, las familias con NSE bajo tuvieron menores oportunidades y se acrecentaron las desigualdades por limitaciones económicas y técnicas, lo cual pudo haber influido en las calificaciones y rendimiento académico de los alumnos. Objetivo: identificar la relación entre el NSE y el rendimiento académico de un grupo de estudiantes de licenciatura en enfermería durante la pandemia COVID-19. Metodología: estudio transversal, cuantitativo, analítico, con alumnos que tuvieron educación a distancia, se utilizó el instrumento denominado Nivel Socioeconómico (NSE) de la Asociación Mexicana de Agencias de Inteligencia de Mercado y Opinión Pública (AMAI), así como los promedios del semestre cursado en línea Resultados: participaron 167 alumnos, entre las variables de rendimiento académico y nivel socioeconómico se obtuvo un valor de p = 0.961, para las variables de sexo y estado civil se encontró asociación con un valor de p < 0.05. Conclusiones: no se identificó ninguna relación entre las variables del rendimiento académico y el nivel socioeconómico; sin embargo, otras variables como estado civil y sexo dieron significancia estadística, por lo que se sugiere ahondar en estas variables, así como su relación con el rendimiento académico.
Introduction: The socioeconomic level (SES) of families has a fundamental role in the academic performance of students, during the pandemic families with a low SES had fewer opportunities and increased inequalities due to economic and technical limitations, which could influence grades and academic performance. of the students Objective: To identify th e relationship between the SES and aca demic performance of nursing undergraduate students during COVID-19. Methodology: Cross-sectional, quantitative, analytical study with students who had distance education, the instrument called Socioeconomic Level (NSE) of the Mexican Association of Market Intelligence Agencies and Public Opinion (AMAI) was used. and the averages of the semester completed online. Results: 167 students participated, between the variables of academic performance and socioeconomic level a value of p = 0.961 was obtained, for the variables of sex, marital status an association was found with a p value less than 0.05. Conclusions: No relationship was identified between the variables of academic performance and socioeconomic level, however, other variables such as marital status and sex gave statistical significance, so it is suggested to delve into these variables as well as their relationship with academic performance.

In this study, the use of Mtp-40 and alpha antigen polymerase chain reaction (PCR) amplification fragments for the precise tuberculosis (TB) diagnosis was evaluated. One hundred and ninety two different samples were obtained from 113 patients with suspected TB. Mtp-40 and alpha antigen protein genes were amplified by the PCR technique and compared to both the "gold standard" (culture) test, as well as the clinical parameters (including a clinical record and X-ray film exam in 113 patients). Thirty-eight of the 113 patients had a presumptive clinical diagnosis of TB; 74 percent being detected by PCR technique, 58 percent by culture and 44 percent by direct microscopic visualization. Weconclude that it is possible to use PCR as a suitable technique for the detection of any mycobacteria by means of the alpha antigen product, or the specific infection of Mycobacterium tuberculosis by means of the mtp-40 gene. This might be a good supporting tool in difficult clinical TB diagnosis and pauci-bacillary cases

Differential display technique was applied in order to identify transcripts which are present in axenic amastigotes but not in promastigotes of the Leishmania panamensis parasites. One of them was cloned and the sequence reveals an open reading frame of 364 amino acids (aprox. 40 kDa). The deduced protein is homologous to the serine/threonine protein kinases and specially to the mitogen activates protein kinases from eukaryotic species. Southern blot analysis suggest that this transcript, named lpmkh, is present in the genome of the parasite as a single copy gene. These results could imply that lpmkh could be involved in the differentiation process or the preservation of amastigotes in axenic conditions
