Filter by:Urinary tract infection is a common infectious disease in clinic. Although urinary tract infection can be initially diagnosed by clinical sign and symptom, signs and urine routine, the application of appropriate antibiotic therapy depends on the further identification of pathogens. Metagenomic sequencing has been widely used in clinical pathogen diagnosis, especially in difficult infectious diseases. ICompared with tissue samples, cerebrospinal fluid, bronchoalveolar lavage fluid, whole blood and other samples, the application of mNGS in urine samples is relatively limited because incorrect sampling methods before and after collection of urine samples are easy to contaminate the samples and the colonization of distal urethra, periurethral skin and vagina will interfere with the interpretation of reports. Previous small sample studies have shown that the sensitivity of mNGS in urinary tract infection is high, but the specificity is relatively low, and there are many problems such as difficult interpretation of reports and low clinical conformity. This is closely related to the mNGS technology algorithm, such as the inability to eliminate the influence of urinary system background bacteria, and the ambiguity of short sequence alignment, which makes it difficult to distinguish homologous pathogens. In this study, based on the standard mNGS sequencing process, the improved Z value analysis method was used to select strictly enrolled clinical samples and compare them with pathogen culture to observe the clinical value of mNGS with Z value analysis method in the treatment of urinary tract infection.
Identifying multiorgan sequalae and complications through high quality, prospective matched controlled studies throughout the course of COVID-19 is important for the acute and long-term management of patients and for health systems' planning. Further, it is key to understand the link between acute illness and long term consequences particularly in those already living with other comorbidities such as cardiovascular diseases or cancer. Since the clinical presentation of COVID-19 can resemble a variety of common respiratory infections, describing the distribution of pathogens and the severity of clinical presentation associated with COVID-like illnesses (CLI) infections is important to generate a baseline clinical description by comparing potential long-term effects of PCR-confirmed COVID-19 to those following other respiratory infections. To gain a better understanding of the clinical burden on COVID-19 survivors we will undertake a comparative evaluation within a cohort of PCR-confirmed individuals with COVID-19 vs. those PCR-confirmed symptomatic individuals with other respiratory pathogens plus healthy individuals from the community. The results will inform strategies to prevent long term consequences; inform clinical management, interventional research, direct rehabilitation, and inform public health management to reduce overall morbidity and improve outcomes of COVID-19.
