and Gene Variants Are Associated With Severe Outcomes of COVID-19 in Men.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the current coronavirus disease 2019 (COVID-19) pandemic, affecting more than 219 countries and causing the death of more than 5 million people worldwide. The genetic background represents a factor that predisposes the way the host responds to SARS-CoV-2 infection. In this sense, genetic variants of and could explain the observed interindividual variability to COVID-19 outcomes.

Contemporary management of urinary tract stone disease in children within a high volume institution in Mexico.

Objetivo: La urolitiasis en pacientes pediátricos es una condición de baja frecuencia, con tendencia hacia el aumento, por lo que es importante actualizar a urólogos sobre las opciones terapéuticas actuales. Describir las características clínicas, las técnicas quirúrgicas y sus resultados usadas para el tratamiento de la urolitiasis en pacientes pediátricos.

Materiales Y MÉtodos: El estudio incluyó todos los pacientes menores de 18 años quienes fueron tratados quirúrgicamente por litiasis urinaria desde el año 2017 al 2020, quienes poseían expedientes clínicos completos y seguimiento en el Hospital General de México.

Association between cycle threshold (C ) values and clinical and laboratory data in inpatients with COVID-19 and asymptomatic health workers.

In-house assays for the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by quantitative reverse-transcription polymerase chain reaction (qRT-PCR), are feasible alternatives, particularly in developing countries. Cycle threshold (C ) values obtained by qRT-PCR were compared with clinical and laboratory data from saliva of inpatients with COVID-19 and asymptomatic health workers (AHW) were studied. Saliva specimens from 58 inpatients confirmed by qRT-PCR for SARS-CoV-2 using nasopharyngeal specimens, and 105 AHW were studied by qRT-PCR using three sets of primers for the N (N1, N2, and N3) gene of SARS-CoV-2, according to the CDC Diagnostic Panel protocol, showing a positivity of 88% for inpatients and 8% for AHW.
