21% were eligible for thromboprophylaxis. Routine VTE risk assessment rate increased significantly following its incorporation into quality parameters, but the rate of treated patients was low (22% at 2013; 46% at 2018). The patients who received thromophylaxis were sicker compared to eligible patients without thromboprophylaxis. The rate of symptomatic VTE was low (0.24%; 0.12% and 0.55% for low and high VTE risk, respectively). Thromboprophylaxis did not have significant effect on the low number of VTE events. No major bleeding was observed.Major efforts are still needed to increase the rate of thromboprophylaxis in all eligible medical patients according to the guidelines recommendations.Structural differences have been reported between primary open angle glaucoma (POAG) and normal tension glaucoma (NTG), and biomechanical differences between POAG and NTG may account for why NTG patients are more vulnerable to lower intraocular pressure (IOP). This study compared the biomechanical properties of POAG and NTG patients using the Corvis scheimpflug technology (ST) non-contact Scheimpflug-based tonometer, and determined the factors associated with these properties.In this retrospective cross-sectional study, 46 eyes with POAG, 54 eyes with NTG, and 61 control eyes were included. A non-contact Scheimpflug-based tonometer was used to examine and compare the corneal biomechanical responses in the POAG, NTG, and normal groups. We used univariate and multivariate regression analyses to determine the factors associated with the deformation amplitude in each group.Baseline characteristics, including age, IOP, spherical equivalent, keratometry, axial length, and central corneal thickness, were similar amothe differences in biomechanical properties between POAG and NTG may contribute to a better understanding of the underlying pathophysiologies associated with these diseases.Our objective in this study was to determine the survival rate of patients with invasive breast cancer and identify the prognostic factors related to all-cause mortality during a 10-year follow-up.Analysis was performed on the medical records of 2002 patients newly diagnosed with breast cancer at a medical center in southern Taiwan between 2006 and 2017. The Kaplan-Meier method and Cox regression analysis were used to estimate survival and the independence of prognostic factors associated with all-cause mortality.Among the 2002 patients, 257 expired during the 10-year follow-up period. The overall survival rates were as follows 3 years (91.1%), 5 years (85.6%), and 10 years (77.9%). The median survival time was 120.41 months (95% confidence interval 118.48-122.33 months). Older age, pathologic tumor status, regional lymph node metastasis, distant metastasis, grade/differentiation, treatment modalities, and hormone therapy were significantly related to all-cause mortality.This study identified several clinical factors related to all-cause mortality as well as its relationship to distant metastasis and poor differentiation. Early diagnosis and treatment aimed at preventing recurrence are the keys to survival.Cigarette smoking is considered the main risk factor for chronic obstructive pulmonary disease (COPD), although the mechanism remains unknown. surfactant protein A (SP-A) is thought to protect the lung from smoking-induced damage, but related studies performed in China are scarce. The aim of the study is to assess alterations of SP-A expression and distribution in lung samples from Chinese smokers with or without COPD.This cross-sectional study assessed 45 men in Wuhan Tongji Hospital after lobectomy for lung cancer in June 2010 to September 2010. Peripheral lung specimens were collected from control nonsmokers without airflow obstruction (nonsmoking group, n = 15), smokers without airflow obstruction (smoking group, n = 15), and patients with COPD (COPD group, n = 15). SP-A expression levels in lung tissue samples and its distribution in lung cells, type II pneumocytes (PNII), and alveolar macrophages (MACR) were determined by immunoblotting and immunohistochemistry.SP-A levels were significantly decreased in the COPD group (1.00 ± 0.25) compared with the smoking (2.31 ± 0.64) and nonsmoking (8.03 ± 2.80) groups; the smoking group also showed significantly reduced levels compared with the nonsmoking group (P  less then  .05). PNII expressing SP-A were less abundant in the COPD group (39.3% ± 7.1%) compared with the smoking group (76.2% ± 29.8%), whereas SP-A MACR were more abundant (92.4% ± 7.1% vs 68.5% ± 20.2%) (all P  less then  .05).  https://www.selleckchem.com/products/chir-98014.html  Among the 30 smokers, forced expiratory volume in one second (% predicted) was positively correlated with SP-A levels (r = 0.739) and the rate of SP-A+ PNII (r = 0.811), and negatively correlated with the rate of SP-A+ MACR (r = -0.758) (all P  less then  .05).Changes in SP-A expression and distribution in lung tissues may be involved in COPD pathogenesis in smokers.INTRODUCTION Thoracic diseases include a variety of common human primary malignant tumors, among which lung cancer and esophageal cancer are among the top 10 in cancer incidence and mortality. Early diagnosis is an important part of cancer treatment, so artificial intelligence (AI) systems have been developed for the accurate and automated detection and diagnosis of thoracic tumors. However, the complicated AI structure and image processing made the diagnosis result of AI-based system unstable. The purpose of this study is to systematically review published evidence to explore the accuracy of AI systems in diagnosing thoracic cancers. METHODS AND ANALYSIS We will conduct a systematic review and meta-analysis of the diagnostic accuracy of AI systems for the prediction of thoracic diseases. The primary objective is to assess the diagnostic accuracy of thoracic cancers, including assessing potential biases and calculating combined estimates of sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). The secondary objective is to evaluate the factors associated with different models, classifiers, and radiomics information. We will search databases such as PubMed/MEDLINE, Embase (via OVID), and the Cochrane Library. Two reviewers will independently screen titles and abstracts, perform full article reviews and extract study data. We will report study characteristics and assess methodological quality using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. RevMan 5.3 and Meta-disc 1.4 software will be used for data synthesis. If pooling is appropriate, we will produce summary receiver operating characteristic (SROC) curves, summary operating points (pooled sensitivity and specificity), and 95% confidence intervals around the summary operating points. Methodological subgroup and sensitivity analyses will be performed to explore heterogeneity. PROSPERO REGISTRATION NUMBER CRD42019135247.
