Remote Longitudinal Inpatient Acute Stroke Care Via Telestroke.

Objectives: While telestroke 'hub-and-spoke' systems are a well-established model for improving acute stroke care at spoke facilities, utility beyond the hyperacute phase is unknown. In patients receiving intravenous thrombolysis via telemedicine, care at spoke facilities has been shown to be associated with longer length of stay and worse outcomes. We sought to explore the impact of ongoing stroke care by a vascular neurologist via telemedicine compared to care provided by local neurologists.

Insufficient lymph node assessment in gastric adenocarcinoma.

Background: This study aimed to investigate the sufficient (≥ 16) lymph node assessment in 449 patients with gastric adenocarcinoma and literature review.

Methods: Four hundred and forty-nine patients with pathologically confirmed locoregional invasive gastric adenocarcinoma from 2004 to 2013 were included. A standard surgical resection was performed for all the patients with (n = 16) or without (n = 433) neoadjuvant treatment.

Neuromuscular complications of immune checkpoint inhibitor therapy.

Immune checkpoint inhibitor (ICPI) therapy unleashes the body's natural immune system to fight cancer. ICPIs improve overall cancer survival, however, the unbridling of the immune system may induce a variety of immune-related adverse events. Neuromuscular immune complications are rare but they can be severe.

Hypo-Vascular Liver Metastases Treated with Transarterial chemoembolization: Assessment of Early Response by Volumetric Contrast-Enhanced and Diffusion-Weighted Magnetic Resonance Imaging.

Objective: To evaluate the value of anatomic and volumetric functional magnetic resonance imaging (MRI) in early assessment of response to trans-arterial chemoembolization (TACE) in hypovascular liver metastases.

Methods: This retrospective study included 52 metastatic lesions (42 targeted and 10 non-targeted) in 17 patients who underwent MRI before and early after TACE. Two reviewers reported response by anatomic criteria (Response Evaluation Criteria in Solid Tumor [RECIST], modified RECIST [mRECIST], and European Association for the Study of Liver Disease [EASL]) and functional criteria (volumetric apparent diffusion coefficient and contrast enhancement).

Impact of Perioperative Phosphorus and Glucose Levels on Liver Regeneration and Long-term Outcomes after Major Liver Resection.

Introduction: The impact of phosphorus as well as glycemic alterations on liver regeneration has not been directly examined. We sought to determine the impact of phosphorus and glucose on liver regeneration after major hepatectomy.

Methods: Early and late liver regeneration index was defined as the relative increase of liver volume (RLV) within 2[(RLV2m-RLVp)/RLVp] and 7 months[(RLV7m-RLVp)/RLVp] following surgery.

Liver regeneration after major liver hepatectomy: Impact of body mass index.

Background: Obese patients may present with metabolic abnormalities that impact liver regeneration. We sought to assess the impact of body mass index (BMI) on liver volume regeneration index (RI) and kinetic growth rate (KGR) among patients undergoing liver resection.

Methods: The study included 102 patients undergoing major hepatectomy (≥3 segments) between July 2004 and April 2015 and stratified the patients by preoperative BMI, number of segments resected, and postoperative remnant liver volume (RLVp) to total liver volume ratio.

Quantitative volumetric functional MR imaging: an imaging biomarker of early treatment response in hypo-vascular liver metastasis patients after yttrium-90 transarterial radioembolization.

Purpose: To evaluate the value of quantitative volumetric functional MR imaging in early assessment of response to yttrium-90-labeled ((90)Y) transarterial radioembolization (TARE) in patients with hypo-vascular liver metastases.

Materials And Methods: Seventy four metastatic lesions in 14 patients with hypo-vascular liver metastases after TARE were included in this retrospective study. Diffusion and contrast-enhanced MR imaging was performed before and early after treatment.

Magnetic Resonance Imaging in Diagnosis and Monitoring of Hepatocellular Carcinoma in Liver Transplantation: A Comprehensive Review.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer. One of the most important risk factors of HCC is cirrhosis. The optimal treatment of HCC is liver transplantation, since it treats both the underlying cirrhosis and the cancer.

Liver Malignancies Treated With Intra-Arterial Therapy: Assessment of Early Response as Quantified by Volumetric Enhancement Using Gadoxetate Disodium.

Objective: The aim of the study was to evaluate the value of volumetric contrast-enhanced magnetic resonance imaging (MRI) using gadoxetate disodium in early assessment of treatment response after intra-arterial therapy (IAT).

Materials And Methods: This prospective study included 21 patients (32 malignant lesions) who underwent MRI using gadoxetate disodium before and early after IAT. Two reviewers reported response by anatomic criteria including Response Evaluation Criteria in Solid Tumor (RECIST), Modified RECIST (mRECIST), and European Association for the Study of Liver Disease and functional criteria including volumetric enhancement in hepatic arterial phase and portal venous phase.

Expression of rhesus blood group antigens in HTLV-i infection in northeast Iran.

Background: Human T-cell lymphoma/leukemia virus type 1 (HTLV-1) infection is relatively common in northeast Iran. It is important to understand which factors play a role in the pathogenesis of this virus. Blood group antigens may act as a receptor for various infectious agents.
