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. Nintedanib 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. 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=0.003), and higher plasma brain natriuretic peptide (BNP) level (P=0.006). Multivariate Cox regression analysis showed that there were higher risks of MACE [hazard ratio (HR) 11.20, 95% confidence interval (CI) 3.18-39.52, P<0.001)] and heart failure (HR 27.10, 95% CI 4.65-157.83, P<0.001) in the high-level group.

The present study suggested that plasma SIRT2 level is a promising biomarker to predict heart failure and MACE after AMI.

There have been many studies on the effectiveness and complications of airway stent, but few had focused on factors that affect survival after stent placement. This study intended to assess the factors associated with the survival in patients with malignant central airway obstruction (MCAO) after airway metallic stent placement.

The clinical data of adult MCAO patients who underwent stent placement form February 2003 to June 2017 in the First Affiliated Hospital of Soochow University in China were retrospectively analyzed. The survival rates were compared using Log-rank tests. Potential prognostic factors were identified using multivariate Cox hazard regression models.

Total 102 MCAO patients were included in this study. The median survival time of these patients after airway metallic stent placement was 4.1 months. Multivariate analysis showed that MCAO patients receiving radiotherapy [hazard ratio (HR) 0.554; 95% confidence interval (CI) 0.308-0.999] or chemoradiotherapy (HR 0.251; 95% CI 0.126-0.499) after stenting had better prognosis. However, ECOG PS ≥3 score prior to the stenting (HR 2.193; 95% CI 1.364-3.526) and stents placed in both trachea and main bronchus (HR 2.458; 95% CI 1.384-4.366) were associated with worse survival.

In our results, survival of MCAO patients after airway metallic stenting was related to ECOG PS score prior to the stenting, the site of stent placement and we have hereby proposed for the first time that having opportunity to receive radiotherapy or chemoradiotherapy after stenting contribute to better prognosis.

Daily evaluation of peak expiratory flow rate (PEFR) is quite useful for monitoring and adjusting an asthmatic patient's treatment. Many factors including geography, ethnicity, socio-economic conditions, gender, and anthropometric play a role in lung function differences studies have found. The aim of this study is to present normal PEFR and to establish a PEFR equation for Thai children living in a suburban environment.

This study includes a cross-section of healthy children aged 6 to 18. It was conducted in Phitsanulok Province in the lower north of Thailand. The children were chosen to participate from five primary and secondary schools over the period from February 2014 to January 2015. The children were instructed on how to use the Wright peak flow meter (Clement Clarke International Ltd.). All of the participants performed PEFR 3 times and the highest value was recorded.

A total of 2,000 students were initially examined; 80 students were excluded from the study. A total of 1,920 healthy children wEFR for each sex in the regression equation.
This research study has provided the normal range of PEFR for Thai children aged from 6 to 18 years in Phitsanulok. The data was obtained using the Wright peak flow meter. Height, weight, and age were the significant determiners of the PEFR for each sex in the regression equation.
Supraclavicular lymph node metastasis (SCLN) is an adverse prognostic determinant of esophageal cancer. However, lymphadenectomy for SCLN is a traumatic procedure, especially in elderly patients, which is associated with more postoperative complications. Currently, identification of risk factors of SCLN metastasis and avoidance of unnecessary lymphadenectomy for SCLN in esophageal squamous cell carcinoma (ESCC) patients has become an unmet clinical need.

A total of 90 elderly patients with ESCC between January 2008 and December 2013 was eligible for this analysis. Logistic regression was performed to determine risk factors for SCLN metastasis after ESCC radical surgery in elderly patients. A nomogram was constructed to individually predict the risk for SCLN metastasis. The Kaplan-Meier survival curve and cumulative risk curve were further analyzed to evaluate the effect of SCLN metastasis after ESCC radical surgery on survival prognosis and cumulative risk assessment in elderly patients. Finally, the SCLNth esophageal squamous cell carcinoma (ESCC).
Postoperative lymph node metastasis, tumor thrombus and tumor infiltration are independent risk factors for recurrence and metastasis of SCLNs in elderly patients with esophageal squamous cell carcinoma. The nomogram model based on these factors provides a preliminary reference for individualized risk assessment, prognosis guidance and decision-making of SCLN metastasis in elderly patients with esophageal squamous cell carcinoma (ESCC).
