Background: While recent genome wide association studies have suggested novel low-grade glioma (LGG) stratification models based on a molecular classification, we explored the potential clinical utility of patient-derived cells. Specifically, we assayed glioma-associated stem cells (GASC) that are patient-derived stem cells representative of the glioma microenvironment. Methods: By next generation sequencing, we analyzed the transcriptional profile of GASC derived from patients that underwent anaplastic transformation either within 48 months (GASC-BAD) or ≥7 years (GASC-GOOD) after surgery...

BACKGROUND: Incisional hernia is a frequent complication after midline laparotomy. Surgical hernia repair is associated with complications, but no clear predictive risk factors are identified. The European Hernia Society (EHS) classification offers a structured framework to describe hernias and to analyze postoperative complications. Because of its structured nature, it might prove to be useful for preoperative patient or treatment classification. The objective of this study was to investigate the EHS classification as a predictor for postoperative complications after incisional hernia surgery...

Acute limb ischemia is technically defined as ischemia of the lower extremities lasting 14 days or less. The condition affects between 15 and 26 persons per 100,000 each year in the United States. The associated morbidity and mortality is extremely high, with 1-year mortality rates reported at over 40%. Acute limb ischemia is 20 times more common in the lower extremities than the upper extremities. Both interventional radiologists and vascular surgeons bring unique skills to the table in caring for these patients, and therefore should approach the care of these patients in a multidisciplinary manner to ensure the best outcomes for each patient...

Three-dimensional (3D) visualization technology in pancreatic head cancers could offer decision-making support to preoperative diagnosis, resectability assessment and individualized surgical planning. In addition, the pancreas 3D printing helps to realize the leapfrog development from 3D images to 3D physical models and provides better guidance of the precise surgery of complicated cancers of the pancreatic head. In order to standardize the application of 3D visualization and 3D printing technology in the diagnosis and treatment of pancreatic head cancer, Chinese experts in relevant fields were organized by four committees to formulate this expert consensus...

A 35-year-old woman had undergone extensive thymothymectomy for type A thymoma several years ago. However, two small lung nodules were found 4 and 5 years after surgery. After a partial lung resection to remove these nodules, pathology revealed that they were metastases of the type A thymoma. A pathological re-evaluation confirmed that the primary tumor had in fact been an atypical type A thymoma variant, a subset added to the WHO classification in 2015. Pathology should be re-evaluated in all patients diagnosed with type A thymoma before 2015 since they may have the more aggressive atypical type A thymoma variant...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is hyperplasia of noninvasive neuroendocrine cells originating from Kultchitsky cells. This is a rare pathological condition, suspected to be a precursor lesion of carcinoid, together with tumorlet. In the WHO histological classification (4th edition) revised in 2015, DIPNECH was added to the category that includes neuroendocrine tumors. Our patient was a 77-year-old woman who initially visited another doctor because of coughing. Chest CT revealed a mass occluding the right intermediate bronchial trunk, and bronchial carcinoid was suspected from biopsy findings, leading to referral of this patient to our department...
