In order to fully elucidate the association between serum fibrinogen and prognosis of esophageal cancer, we examined serum fibrinogen concentrations in 1512 patients who underwent esophagectomy by the Clauss method. The impact of fibrinogen on overall survival and disease-free survival was analyzed using the Kaplan-Meier method and Cox proportional hazard models. Hyperfibrinogenemia was significantly associated with older age, male gender, smoking, alcohol consumption, weight loss, advanced pathological T stage and lymph node metastasis. Patients with hyperfibrinogenemia exhibited poor OS (HR=1.20, 95%CI: 1.04-1.38, P=0.012) and DFS (HR=1.18, 95%CI: 1.03-1.35, P=0.019). Subgroup analysis further exhibited an significant association between hyperfibrinogenemia and poor OS (P<0.001), DFS (P<0.001) in esophageal squamous cell carcinoma (P<0.001) and early pathological stage (I-II) (P=0.001). Collectively, this study indicates that preoperative serum fibrinogen is an independent prognostic factor for survival in esophageal cancer.

Serum levels of vitamin D (VD) are inversely correlated with the incidence or severity of COVID-19. This study aimed to investigate the effects of inactivated COVID-19 virus (ICoV-19) immunization on VD levels, as well as biochemical and hematological parameters in adult male Sprague-Dawley rats. Twenty rats were randomly divided into two groups of 10: the control group (group I) and the ICoV-19-receiving group (group II).

Rhodococcus equi (R. equi) is a primary cause of pyogranulomatous pneumonia of foals between three weeks and five months of age. Early diagnosis of rhodococcal pneumonia has always been considered a preferable approach as it can lead to more successful treatment and better outcomes.

Different kinds of proteins interact with the digestible lipids in various ways, affecting the adsorption behavior of proteins and digestion. The ordered porous layer interferometry (OPLI) system was constructed by the silica colloidal crystal (SCC) films used to monitor the real-time binding assessment between bovine serum albumin (BSA), casein, fibrinogen, and triolein. The OPLI system reflected the changes in protein mass on the SCC films in real time through the migration of the interference spectrum of the SCC films, which was converted into the changes in optical thickness (ΔOT) that can be monitored.

Objectives: To investigate the impact of the different proportions of crescent formation on clinical manifestations and pathological features in children with immunoglobulin A vasculitis with nephritis (IgAVN).
Methods: The children with IgAVN were divided into no-crescent group (75 children), ≤25% crescent group (156 children), and >25% crescent group (33 children).
Results: Compared with the no-crescent group, the other two groups had significant increases in 24-hour urinary protein, urinary immunoglobulin G (IgG)/creatinine ratio, urine red blood cell count, fibrinogen, and neutrophil-lymphocyte ratio, a significant reduction in serum IgG, and a significantly higher proportion of children with low albumin and hypercoagulability, pathological grade III+IV or diffuse mesangial proliferation (<0.
Analysis of risk factors for sepsis-related liver injury and construction of a prediction model.

Background: Sepsis is a leading cause of mortality in critically ill patients, and the liver is a key organ affected by sepsis. Sepsis-related liver injury (SRLI) is an independent risk factor for multiple organ dysfunction syndrome (MODS) and mortality. However, there is no clear diagnostic standard for SRLI, making early detection and intervention challenging.
