We evaluate whether the survival of lung cancer patients with and without CKD differ significantly using two different formulas.
Methods: A retrospective, multicenter, propensity-matched study of lung cancer patients with and without CKD was conducted.
Introduction: The expression of programmed death 1 (PD1) and programmed death ligand 1 (PDL1) can be induced by the interferon (IFN)/signal transducer and activator of transcription (STAT) pathway. The PD1/PDL1 reverse signaling can activate the eukaryotic translation initiation factor 2 (eIF2)/activating transcription factor 4 (ATF4) pathway which in turn regulates the expression of IFN regulatory factor (IRF) 7 and IFN. The eIF2/ATF4 pathway is responsible for the integrated stress response (ISR) of unfolded protein response (UPR) which can affect immune cell function in tumor microenvironment.

Methods: Twenty-four adolescents with primary spontaneous pneumothorax were enrolled prospectively. A global gene expression analysis of 9 paired lung biopsies (lesion and normal adjacent sites) was performed to identify differentially expressed genes associated with spontaneous pneumothorax.
Introduction: The efficacy of antiplatelet agents in preventing thrombosis in newly formed arteriovenous graft (AVG) in hemodialysis (HD) patients has been extensively examined. The aim of this study was to investigate the possible effect of initiation of antiplatelet medications on preventing AVG thrombosis recurrence after surgical thrombectomy for acute occlusion in HD patients. Whether post-operatively antiplatelet medications have protective effects on the patency or longevity of AVG after surgical thrombectomy in HD patients has not been investigated.

The purpose of this study was to investigate the relationship of the variability in SBP and the magnitude of renal function impairment for normal renal function patients in the first 10-years diagnosed with type II diabetes mellitus (DM).
Methods: We retrospectively reviewed the electronic medical records of 789 patients who were first diagnosed with diabetes mellitus during 2000-2002 and regularly followed for 10 years with a total of 53,284 clinic visits.
Background: The selection of ideal candidates for surgical intervention among patients with parapneumonic pleural effusion remains challenging. In this retrospective study, we sought to identify the main predictors of surgical treatment and devise a simple scoring system to guide surgical decision-making.
Method: Between 2005 and 2014, we identified 276 patients with parapneumonic pleural effusion.

View Article and Find Full Text PDFObjectives: To study the effect of antiplatelet agents on preventing arteriovenous (AV) fistulae thrombosis in hemodialysis (HD) patients after surgical thrombectomy (ST) for acute AV fistulae occlusion. Whether post-operative antiplatelet drugs have similar effects on the patency of AV fistula after surgical thrombectomy in patients with end-stage renal disease who undergo HD has not been investigated.
Design, Materials And Methods: We employed the Taiwan National Health Insurance Research Database (NHIRD) from 1999 to 2010 to assess the recurrent occlusion requiring ST and longevity of AV fistula after ST in 1049 patients on regular HD, with or without antiplatelet drugs.
Introduction: Safe pulmonary vessel sealing device plays a crucial role in anatomic lung resection. In 2014, we reported high rates of massive bleeding complications during transumbilical lobectomy in a canine model due to difficulty in managing the pulmonary vessel with an endostapler. In this animal survival series, we aimed to evaluate the outcome of pulmonary vessel sealing with an electrocautery device to simplify the transumbilical thoracic surgery.
View Article and Find Full Text PDFPurpose: Transumbilical single-port surgery has been associated with less postoperative pain and offers better cosmetic outcomes than conventional 3-port laparoscopic surgery. This study compares the safety and efficacy of transumbilical thoracoscopy and conventional thoracoscopy for lung wedge resection.
Methods: The animals (n = 16) were randomly assigned to the transumbilical thoracoscopic approach group (n = 8) or conventional thoracoscopic approach group (n = 8).
Purpose: The use of video-assisted thoracoscopic surgery (VATS) in patients with thymoma remains controversial. We sought to evaluate the perioperative and oncological outcomes after VATS resection for stage I and II thymoma and to compare the outcomes with those obtained after median sternotomy (MST).
Methods: Between 1991 and 2007, a total of 140 patients with stage I and II thymoma underwent surgery at the Chang Gung Memorial Hospital.
Unlabelled: Primary spontaneous pneumothorax (PSP) is not uncommon, and its recurrence is often a challenging clinical problem. Surgical management and predisposing factors for the recurrence of PSP, however, have not yet been well elucidated in adolescent patients. The major aim of this study was to investigate factors associated with proceeding to surgical intervention and recurrence of PSP in adolescents.
