tilation.Pulmonary fibrosis is one of the important causes of morbidity and mortality in fibroproliferative disorders such as systemic sclerosis (SSc) and idiopathic pulmonary fibrosis (IPF). Lysyl oxidase (LOX) is a copper-dependent amine oxidase whose primary function is the covalent crosslinking of collagens in the extracellular matrix (ECM). We investigated the role of LOX in the pathophysiology of SSc. LOX mRNA and protein levels were increased in lung fibroblasts of SSc patients compared with healthy controls and IPF patients. In vivo, bleomycin induced LOX mRNA expression in lung tissues, and LOX activity increased in the circulation of mice with pulmonary fibrosis, suggesting that circulating LOX parallels levels in lung tissues. Circulating levels of LOX were reduced upon amelioration of fibrosis with an antifibrotic peptide. LOX induced ECM production at the transcriptional level in lung fibroblasts, human lungs, and human skin maintained in organ culture. In vivo, LOX synergistically exacerbated fibrosis in bleomycin-treated mice. Further, LOX increased the production of interleukin (IL)-6, and the increase was mediated by LOX-induced c-Fos expression, the nuclear localization of c-Fos, and its engagement with the IL-6 promoter region. Our findings demonstrate that LOX expression and activity correlate with fibrosis in vitro, ex vivo, and in vivo. LOX induced ECM production via upregulation of IL-6 and nuclear localization of c-Fos. Thus, LOX has a direct pathogenic role in SSc-associated fibrosis that is independent of its crosslinking function. Our findings also suggest that measuring circulating LOX levels and activity can be used for monitoring response to antifibrotic therapy.

Elderly trauma patients are at risk for undertriage, resulting in substantial morbidity and mortality. The objective of this study was to determine whether implementation of geriatric-specific trauma team activation (TTA) protocols appropriately identified severely-injured elderly patients.

This single-center retrospective study evaluated all severely injured (injury severity score [ISS] >15), geriatric (≥65 years) patients admitted to our Level 1 tertiary-care hospital between January 2014 and September 2017. Undertriage was defined as the lack of TTA despite presence of severe injuries. The primary outcome was all-cause in-hospital mortality; secondary outcomes were mortality within 48 hours of admission and urgent hemorrhage control. TAK-779 cost A multivariable logistic regression analysis was performed to identify predictors of appropriate triage in this study.

Out of 1039 severely injured geriatric patients, 628 (61%) did not undergo TTA. Undertriaged patients were significantly older and had more comorbidie much lower morbidity and mortality, suggesting the geriatric-specific TTA guidelines identify those patients at highest risk for poor outcomes.This study evaluates the feasibility of retrohepatic inferior vena cava (RHIVC) resection without reconstruction in patients with end-stage hepatic alveolar echinococcosis (AE). Four hundred and fifty-seven patients diagnosed with hepatic AE and who underwent surgical resections between January 2010 and October 2018 were retrospectively analyzed. Nine patients receiving RHIVC resection without reconstruction were included in this study. Among the patients, 5 were male and 4 female. Mean follow-up time was 64.4 months (18-95). In this series, adequate collateral circulation was formed before operation in all patients, and 7 cases underwent ex vivo liver resection and autotransplantation (ELRA) and 2 cases underwent extended right hemi-hepatectomy. Average standard liver volume, graft volume, surgical time, and anhepatic phase in ELRA group patients was 1144 ± 127 cm3, 740 ± 235 cm3, 16.8 ± 4.1 hours, and 337.4 ± 108.65 minutes respectively. Average hospital stay time for all patients was 45 ± 36.4 days. There were no intraoperative deaths. The 30-day mortality rate was 11.1%, and total mortality rate was 22.2%. Postoperative complications occurred in 4 patients. During follow-up, no relapsed AE lesions were found. RHIVC resection without reconstruction is a feasible way for hepatic AE patients with adequate collateral circulation. Careful protection of collateral venous is the key factor for successful operation.

The aim of this study was to conduct a meta-analysis comparing the safety and feasibility of laparoscopic versus open resection for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm.

We searched the Cochrane Library, PubMed, and Embase for relevant articles. Randomized and nonrandomized clinical trials were identified and included in this study. Searching for related articles on large GIST (>5 cm) for laparoscopic resection (laparoscopic group [LAPG]) and open resection (open group [OG]), RevMan 5.3 was used for data analysis, comparing 2 groups of operation time, intraoperative blood loss, complications, length of hospital stay, recurrence rate, disease-free survival, and overall survival.

Seven studies including 440 patients were identified for the meta-analysis. Meta-analysis revealed that LAPG had less bleeding, shorter postoperative hospital stay, and a better 5-year disease-free survival. There was no significant difference between LAPG and OG in operation time, postoperative complications, recurrence rate, and overall survival.

Laparoscopic resection of large (>5 cm) GIST is safe and feasible and has the advantages of less intraoperative blood loss and fast postoperative recovery, with a good outcome in the recent oncology.

In 2017, the Accreditation Council for Graduate Medical Education program guidelines changed to include a section that requires programs to optimize resident and faculty member well-being. There is still a poor understanding of general surgery resident wellness, and there are few well-established wellness programs.

We created a novel 50-question anonymous survey to assess burnout, depression, and wellness that was distributed to the general surgery residents as part of a pilot study. Univariate analysis was performed to assess wellness and wellness changes. Bivariate analysis was performed to determine the association between wellness variables and gender, age, and postgraduate year (PGY) level.

Thirty-five of 55 residents participated in the survey. Over half of the residents (54%) reported gaining weight during residency. Nearly 70% reported working while having an ongoing family issue, and 77% worked at least once while ill. TAK-779 cost Fourteen residents (40%) reported that their wellness worsened over the previous academic year, while 7 (20%) reported that it remained the same, and 11 (31%) reported that it improved.
