The tigecycline resistance gene tetX has an expensive fitness cost based on increased outer membrane permeability and metabolic burden in Escherichia coli.

Livestock-derived tetX-positive Escherichia coli with tigecycline resistance poses a serious risk to public health. Fitness costs, antibiotic residues, and other tetracycline resistance genes (TRGs) are fundamental in determining the spread of tetX in the environment, but there is a lack of relevant studies. The results of this study showed that both tetO and tetX resulted in reduction in growth and an increased in the metabolic burden of E.

Serious Risk of Tigecycline Resistance in Escherichia coli Isolated from Swine Manure.

The emergence of the plasmid-mediated tigecycline resistance gene tetX family in pig farms has attracted worldwide attention. The use of tetracycline antibiotics in pig farms has a facilitating effect on the prevalence of the tetX family, but the relationship among its presence, expression, and resistance phenotype in resistant bacteria is unknown. In this study, the presence and expression characteristics of tetracycline resistance genes (TRGs) in 89 strains of doxycycline-resistant E.

Risk Factors of Anastomotic Leakage After Esophagectomy With Intrathoracic Anastomosis.

Anastomotic leakage is one of the most common complications of esophagectomy, it serves as one of the main causes of postoperative death of esophageal cancer. It is of clinical significance to try to discover the risk factors that cause anastomotic leakage. This retrospective study was conducted on 1,257 consecutive esophageal cancer patients who underwent esophagectomy with intrathoracic anastomosis from January 2010 to December 2015 at a high volume cancer center.

Prognostic risk factors for respiratory failure after esophagectomy.

Background: Esophagectomy is a high-risk surgical procedure with significant postoperative morbidity and mortality. Respiratory failure is one of the most common complications after esophageal cancer surgery. The purpose of this study was to explore risk factors that affect the recovery of respiratory failure in this kind of patients.

The Predictive Value of Coefficient of PCT × BG for Anastomotic Leak in Esophageal Carcinoma Patients With ARDS After Esophagectomy.

Anastomotic leak was a potentially severe life-threatening complication of esophagectomy, which drew attention in consequence of progressive dyspnea until acute respiratory distress syndrome (ARDS) due to the early asymptomatic presentation. Respiratory failure, caused by ARDS as the severe presentation of anastomotic leak, is the most common organ failure. CRP (C-reactive protein), procalcitonin (PCT), and Blood G (BG) test are the sensitivity markers for inflammatory, sepsis, and fungemia, respectively.

Prognostic values of interim and post-therapy 18F-FDG PET/CT scanning in adult patients with Burkitt's lymphoma.

Background: The prognostic values of interim and post-therapy fluorine-18-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) and PET/computed tomography (CT) scanning have been confirmed in several subtypes of lymphoma. However, its prognostic value in Burkitt's lymphoma has not been clearly defined. The aim of the present study was to assess the prognostic value of PET/CT scanning during different treatment processes of Burkitt's lymphoma.

Prognostic significance of peripheral monocyte count in patients with extranodal natural killer/T-cell lymphoma.

Background: Extranodal natural killer/T-cell lymphoma (ENKL) has heterogeneous clinical manifestations and prognosis. This study aims to evaluate the prognostic impact of absolute monocyte count (AMC) in ENKL, and provide some immunologically relevant information for better risk stratification in patients with ENKL.

Methods: Retrospective data from 163 patients newly diagnosed with ENKL were analyzed.

Three prognostic factors influence clinical outcomes of primary testicular lymphoma.

The standard treatment of primary testicular lymphoma (PTL) has not been well established. Our study aimed to evaluate the relationship between the prognostic factors and clinical outcomes of PTL. We retrospectively reviewed the clinical records of 43 PTL patients and included the 39 patients who were diagnosed with primary testicular diffuse large B cell lymphoma (DLBCL) for analysis of prognostic factors and assessment of treatment modalities.

Blood lymphocyte-to-monocyte ratio identifies high-risk patients in diffuse large B-cell lymphoma treated with R-CHOP.

Background: Recent research has shown a correlation between immune microenvironment and lymphoma biology. This study aims to investigate the prognostic significance of the immunologically relevant lymphocyte-to-monocyte ratio (LMR), in diffuse large B-cell lymphoma (DLBCL) in the rituximab era.

Methodology/principal Findings: We analyzed retrospective data from 438 newly diagnosed DLBCL patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy.

High Ki-67 expression in diffuse large B-cell lymphoma patients with non-germinal center subtype indicates limited survival benefit from R-CHOP therapy.

Objectives: Rituximab has significantly improved the survival of patients with DLBCL, especially those with non-germinal center B-cell-like (non-GCB) subtype. The impact of Ki-67 expression, an index of proliferation, on the clinical outcomes of patients with DLBCL has largely been unexplored. This study aimed to investigate whether Ki-67 expression is an indicator of outcome in DLBCL patients (especially non-GCB DLBCL patients) treated with standard chemotherapy combined with rituximab.
