The prognostic role of epidermal growth factor receptor mutation in completely resected ampullary adenocarcinoma.

The aim of this study is to make a differential diagnosis and prognosis of the ampullary adenocarcinoma subtypes. We also investigated the role of prognostic markers PD-1 and PD-L1, and epidermal growth factor receptor (EGFR). Local or locally advanced stage ampullary adenocarcinoma patients who had undergone pancreaticoduodenectomy at the time of diagnosis were included.

Effect of Humic Acid on Oxidative Stress and Neuroprotection in Traumatic Spinal Cord Injury: An Experimental Study.

Objective: Traumatic spinal cord injury (TSCI) is an important health problem especially in developing countries with additional socio-economic loss. Humic acids (HA) usually have anti-oxidant, anti-inflammatory, blood-circulating and antiviral effects. We aimed to show effect of HA on neuroprotection in TSCI model.

Does the ACR TI-RADS scoring allow us to safely avoid unnecessary thyroid biopsy? single center analysis in a large cohort.

Introduction: The American College of Radiology (ACR) has recently proposed a guideline that recommends clinicians to perform thyroid fine-needle aspiration biopsy (FNAB) on the basis of ultrasound features. In this study, we focused on nodules for which no biopsy is recommended by the ACR Thyroid Imaging, Reporting and Data System (TI-RADS) guideline.

Subjects And Methods: Two-thousand eight-hundred and forty-seven consecutive patients with thyroid nodules who underwent FNAB according to the 2009 American Thyroid Association (ATA) guideline were included.
