Results: NET objectives were reduction in surgical extent in 49 patients, avoidance of surgery in 31, and treatment until scheduled surgery in 8.

Head positioning in suspected patients with acute stroke from prehospital to emergency department settings: a systematic review and meta-analysis.

Aim: This study aimed to clarify whether the lying-flat position from prehospital to emergency department settings more effectively improves neurological outcomes of patients suspected with acute stroke over the sitting-up position.

Methods: We searched PubMed, the Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi for published randomized controlled trials until September 2019. The study population included patients suspected with acute stroke from prehospital to emergency department settings.

Blood Pressure Level and Variability During Long-Term Prasugrel or Clopidogrel Medication After Stroke: PRASTRO-I.

Background And Purpose: High blood pressure increases bleeding risk during treatment with antithrombotic medication. The association between blood pressure levels and the risk of recurrent stroke during long-term secondary stroke prevention with thienopyridines (particularly prasugrel) has not been well studied.

Methods: This was a post hoc analysis of the randomized, double-blind, multicenter PRASTRO-I trial (Comparison of Prasugrel and Clopidogrel in Japanese Patients With Ischemic Stroke-I).

Systemic Chemotherapy is a Promising Treatment Option for Patients with Colonic Stents: A Review.

Approximately 10% of patients with colorectal cancer (CRC) develop malignant large bowel obstruction (MLBO) at diagnosis. Furthermore, for 35% of patients with MLBO, curative primary tumor resection is unfeasible because of locally advanced disease and comorbidities. The practice of placing a self-expandable metallic stent (SEMS) has dramatically increased as an effective palliative treatment.

Sex Differences in Management and Outcomes of Cardioembolic Stroke: Post HOC Analyses of the RELAXED Study.

Introduction: Experimental models have clearly demonstrated sex differences in the pathophysiology of stroke and prognosis, however clinical evidence remains elusive. In this study, we examined sex differences as a post hoc analysis of RELAXED (Recurrent Embolism Lessened by rivaroxaban, an anti-X agent, of Early Dosing for acute IS and TIA with atrial fibrillation) Study.

Methods: We stratified study participants by sex and compared baseline and clinical characteristics as well as clinical outcomes.

Pancreatic Hamartoma Difficult to Diagnose Preoperatively.

Abdominal ultrasonography in a 70-year-old woman showed a hypoechoic mass, 14 mm in diameter, in the pancreatic body. Computed tomography showed a mass with contrast effect in the pancreatic body. Test results for endocrine factors or tumor markers were normal.

Negative impact of Interhospital Transfer on Clinical Outcomes of Mechanical Thrombectomy for Fast Progressive Stroke.

Objectives: The time-dependence of the clinical outcome of mechanical thrombectomy is higher in the "fast progressor" in whom cerebral ischemia progresses rapidly. The impact of time-consuming interhospital transfer (IT) on the clinical outcome of such patients is unknown. The effect on clinical outcomes of IT of fast progressors was investigated.

Comparisons of Characteristics and Outcomes after Mechanical Thrombectomy for Vertebrobasilar Occlusion with Cardioembolism or Atherosclerotic Brain Infarction: Data from the Tokyo-Tama-Registry of Acute Endovascular Thrombectomy (TREAT).

Background: Some reports suggest the efficacy of mechanical thrombectomy (MT) for acute vertebrobasilar artery (VBA) occlusion. The major causes of VBA occlusion include cardioembolism (CE) and large-artery atherosclerosis (LAA). However, the clinical characteristics of each cause remain unclear, and they might be important for decision making related to the indications and strategy of MT.

Cholecyst-jejunostomy for palliative surgery.

Introduction And Importance: Many cases of unresectable cancer that cause obstructive jaundice require treatment. Depending on the patient's condition in these cases, surgery may be performed to treat jaundice. The main goal of palliative surgery is to improve the quality of life.

Atrial fibrillation and stroke prevention: state of the art-epidemiology and pathophysiology: new risk factors, concepts and controversies.

Atrial fibrillation (AF) increases the risk of thromboembolism, and risk assessment for thromboembolism is necessary for the management of AF patients. CHADS2 and CHA2DS2-VASc scores have been adopted in international guidelines for AF management, but the significance of each risk factor included in these risk scores are sometimes controversial, and the performance of these scores is only modest. There are several other risk factors not included in the scores such as renal dysfunction, low body weight, type of AF (paroxysmal or non-paroxysmal) as well as echocardiographic parameters and blood biomarkers, and physicians should assess patients risk in an integrated manner.

Impact of Blood Pressure Visit-to-Visit Variability on Adverse Events in Patients With Nonvalvular Atrial Fibrillation: Subanalysis of the J-RHYTHM Registry.

Background Blood pressure (BP) variability has reportedly been a risk factor for various clinical events. To clarify the influence of BP visit-to-visit variability on adverse events in patients with nonvalvular atrial fibrillation, a post hoc analysis of the J-RHYTHM Registry was performed.
