Purpose: This study used the Surveillance, Epidemiology, and End Results (SEER) data to investigate changes in incidence, treatment, survival of lung cancer from 1973 2015. Patients methods: The clinical epidemiological patients with were obtained SEER database. Joinpoint regression models estimate rate related survival. Results: From 2015, average incidence was 59.0/100,000 personyears. increased initially, reached a peak 1992, then gradually decreased. A higher observed males than females...

BackgroundNirmatrelvir plus ritonavir (Paxlovid) reduced the risk of hospitalization or death by 89% in high-risk, ambulatory adults with COVID-19. We aimed at studying efficacy and safety Paxlovid hospitalized adult patients SARS-Cov-2 (Omicron BA.2.2 variant) infection severe comorbidities.MethodsWe conducted an open-label, multicenter, randomized controlled trial which comorbidities were eligible assigned a 1:1 ratio to receive either 300 mg nirmatrelvir 100 every 12 h for 5 days standard...

Treatment with inhaled carbon monoxide (CO) has been shown to ameliorate intestinal injury induced by lipopolysaccharide (LPS) or ischemia-reperfusion in experimental animals. We hypothesized that CO intraperitoneal administration (i.p) might provide similar protection against gas. In the present study, 1 h after intravenously receiving 5 mg/kg LPS, rats were exposed either room air 2 ml/kg of 250 ppm i.p for 1, 3, and 6 h. Intestinal tissues collected determine levels platelet activator...

ERBB2 exon 20 insertions (20ins) have been identified as oncogenic drivers in lung cancers. Lung cancer patients with 20ins benefit from afatinib. However, response heterogeneity was observed harboring different subtypes. In this study, we interrogated clinical characteristics ERBB2-mutated Chinese and investigated the outcomes of specific to afatinib.In retrospectively collected genomic profiling data 7,520 sequenced using next-generation sequencing a Clinical Laboratory Improvement...

Abstract Previous studies have identified potential risk factors for pulmonary carcinoid tumors and evaluated the effect of various treatments; however, results were not entirely consistent. We conducted a population‐based study to further explore relevant prognostic issues. extracted cases with from Surveillance Epidemiology End Results database. Cox proportional hazard regression was utilized identify significant factors, which helped establish nomogram predicting long‐term survival....

Background: Pulmonary pleomorphic carcinoma (PPC) is a rare malignancy; unique clinicopathological characteristics and prognosis have not been described. Methods: PPC patient information collected in the Surveillance, Epidemiology, End Results (SEER) database between 2004 2014 were extracted, evaluated, compared with NSCLC data. Overall survival (OS) was evaluated by Kaplan-Meier method. Univariate analysis (UVA) multivariate (MVA) Cox proportional hazards regression identified risk factors...

Objective: To examine the clinical significance of blood lactate (Lac)/serum albumin (Alb) ratio and Lac/Alb × age score for assessing severity prognosis patients with sepsis. Methods: A total 8,029 sepsis, aged >18 years were enrolled between June 2001 to October 2012 from latest version Medical Information Mart Intensive Care III (MIMIC-III v.1.4). The general data obtained hospital records included gender, age, body mass index (BMI), laboratory indices, sequential organ failure assessment...

Abstract Introduction The SARS-CoV-2 Omicron variant has decreased virulence and pathogenicity, yet the number of infections worldwide is unprecedentedly high, with rather high mortality severe disease rate. Chronic kidney (CKD) patients are particularly vulnerable to have unique clinical outcomes. Methods We retrospectively collected data from 2140 hospitalized infection March 29, 2022, May 17, 2022. Demographic characteristics, ancillary examination results, treatments were described....
