Risk factors and predictive model of cerebral edema after road traffic accidents-related traumatic brain injury.

Purpose: Cerebral edema (CE) is the main secondary injury following traumatic brain injury (TBI) caused by road traffic accidents (RTAs). It is challenging to be predicted timely. In this study, we aimed to develop a prediction model for CE by identifying its risk factors and comparing the timing of edema occurrence in TBI patients with varying levels of injuries.

Blast injuries with contrasting outcomes treated by military surgery strategies: A case report.

The treatment strategy for blast injuries is closely linked to the clinical outcome of blast injury casualties. However, the application of military surgery experience to blast injuries caused by production safety accidents is relatively uncommon. In this study, the authors present 2 cases of blast injuries caused by one gas explosion, both cases involved individuals of the same age and gender and experienced similar degree of injury.

Analysis of factors affecting the prognosis of COVID-19 patients and viral shedding duration.

The clinical characteristics of patients with COVID-19 were analysed to determine the factors influencing the prognosis and virus shedding time to facilitate early detection of disease progression. Logistic regression analysis was used to explore the relationships among prognosis, clinical characteristics and laboratory indexes. The predictive value of this model was assessed with receiver operating characteristic curve analysis, calibration and internal validation.

[Eleven fatal cases with A H1N1 influenza in Tianjin].

Objective: To describe the clinical characteristics of fatal cases with confirmed A H1N1 influenza so as to improve the diagnosis and treatment of this severe disease.

Methods: We retrospectively analyzed the medical records of 11 fatal cases with A H1N1 influenza in Tianjin between September 1 and November 4 2009.

Results: There were 6 males and 5 females with a median age of 25 (21 - 36) years old.

[Study on the genotype of Mycobacterium tuberculosis isolates from hospitals in Tianjin].

Objective: To explore the characteristics on molecular epidemiology of Mycobacterium tuberculosis isolates from hospitals in Tianjin area.

Methods: One hundred M. tuberculosis isolated strains were collected in succession from August 16th-December 25th, 2005 in Tianjin Haihe Hospital and genotyped by spoligotyping and multiple locus variable number-tandem repeat(VNTR).
