169; P=0.003), income level, home-road distance, and statin use were inversely correlated with the decline in FEV1. After multivariable analyses, only smoking was consistently associated with the decline in FEV1.

There was no correlation between baseline serum SP-D levels and incident COPD in a general population. Smoking and age were major risk factors for COPD. The effect of serum SP-D levels on the decline in FEV1 needs further investigation.

The short-term efficacy of Dumon stent has been well demonstrated. Across years, however, due to insufficient sample size and absent of the randomized controlled trial, no reliable conclusion could be reach for Dumon stent’s long-term efficacy. So, we conducted the first meta-analysis to evaluate the long-term efficacy and safety of the Dumon stent for benign tracheal stenosis.

Data on related trials were obtained by doing a literature search in PubMed, Web of Science and Cochrane Library. Random-effect and fixed-effect models were used to calculate the efficacy and incidence of complication of Dumon stent placement.

A total of 395 patients from 8 studies were included in this study, revealing that the stability rate was 41.12% (95% CI, 34.85-48.52%) of Dumon stenting. Further, a curative rate of 40.74% (95% CI, 34.92-47.53%), and efficacy of 75.49% (95% CI, 70.89-80.39%) were obtained from this study. Analysis of the incidence of complications indicated 25.04% of migration (95% CI, 17.52-35.79%), 15.66% granulation (95% CI, 9.39-26.11%) and 23.82% of mucus retention 23.82% (95% CI, 13.77-41.20%).

Dumon stent has a moderate efficacy for treating benign tracheal stenosis with approximately 20% incidence of complication, regular bronchoscopy follow-up should be conducted. Thus, further research is required to modified Dumon stenting.

This study aimed to establish an effective prognostic nomogram for surgery of lung cancer in HIV-infected patients.

The nomogram is based on a retrospective study of 51 patients who underwent lung cancer surgery at the Shanghai Public Health Clinical Center from July 2012 to November 2019. Rapamycin cost The predictive accuracy and discriminative ability of the nomogram were determined by concordance index (C-index) and calibration curve analysis. Internal validity was assessed using bootstrapping validation.

Predictors contained in the prognostic nomogram included age, CD4+ cell count, surgery method, and pathological stage. The model displayed good discrimination with a C-index of 0.755 (95% CI 0.715-0.795) and good calibration. A high C-index value of 0.844 was reached after internal validation.

The proposed nomogram may result in more-accurate prognostic predictions for surgery of lung cancer in HIV-infected patients.

The neutrophil-lymphocyte ratio (NLR) has been recognized as a useful marker of poor prognosis in non-cardiac surgery patients. But, the prognostic function of NLR in cardiovascular surgery patients still largely unknown. The aim of this study was to explore the relationship between postoperative NLR and mortality in cardiac surgery patients.

Clinical data were extracted from the Medical Information Mart for Intensive Care III (MIMIC-III) database. Postoperative day 1 (POD-1) NLR of the patients was calculated. All patients were divided into two groups according to the cut-off value of NLR, which was determined using the receiver operating characteristic (ROC) curve and Youden Index. The primary death outcomes were 30-day, 90-day and 1-year mortality. Cox proportional hazard analysis was performed to assess the associations between NLR and 1-year mortality. Logistic analysis was performed to assess the associations between NLR and other outcomes. Multivariate analyses were used to control for confounders.dependent prognostic biomarker for patients with cardiac surgery.

Elevated postoperative NLR was significantly associated with increased short-term and long-term mortality, CRRT rate, longer ICU and hospital stay, prolonged ventilation in patients undergoing cardiac surgery. NLR is promising to be a readily available and independent prognostic biomarker for patients with cardiac surgery.

Frozen elephant trunk (FET) is an established approach to reduce late complications of type A aortic dissection (AADA) by diminishing false lumen perfusion. Currently, surface size of aortic lumina are evaluated using Computed tomography (CT). However, this 2D method is prone to error as it evaluates dissection progression slice by slice. Volume measurement on the other hand can overcome this limitation and deliver better insights in aortic remodeling. Therefore, the aim was to quantify volume changes of the descending and abdominal aorta at short- and mid-term follow-up after FET.

Between April 2015 and March 2018, 20 patients who underwent surgical repair of AADA using the Thoraflex™ Hybrid Plexus (Vascutek, Terumo Aortic, Scotland) were included in this study. We measured volumetric change before surgical treatment, at discharge, at 12 and at 24 months based on CTAs (Computed tomography angiography). Surfaces and volumes have been analyzed using Aquarius iNtuition (TeraRecon Inc., Foster City, CA, USA)tification of volume changes should be included for the assessment of optimal follow-up timing and consecutive procedure planning.

There is currently no evidence regarding the role of plasma Sirtuin2 (SIRT2) level in acute myocardial infarction (AMI) yet. This study assessed the role of plasma SIRT2 in AMI, and investigated the association of plasma SIRT2 level with major adverse cardiovascular events (MACE) and heart failure after AMI.

This is a prospective observational study. A total of 129 AMI patients (mean age 62.2±12.7 years old, male/female 96/33) were included. Cox proportional hazards regression models were used to estimate the association of different SIRT2 levels with MACE and heart failure after AMI.

According to the 75th percentile value of plasma SIRT2 level, we divided all the AMI patients into two groups high-level group (plasma SIRT2 level ≥109.0 pg/mL) and low-level group (plasma SIRT2 level <109.0 pg/mL). Compared with the low-level group, the high-level group had higher percentage of Killip class ≥3 (P<0.001), left ventricular ejection fraction (LVEF) <50% (P=0.007) or even <40% (P=0.012), use of breathing machine(P=0.
