AI Article Synopsis
- The study examined the visualization quality of renal arteries using intravenous Digital Subtraction Angiography (IV DSA) in 62 patients.
- It found that the left renal artery is less clearly visualized due to interference from gas in the stomach and colon, unlike the right renal artery.
- IV DSA is inadequate for visualizing smaller subsegmental arteries and is not suitable for tumor angiography; proper patient preparation is essential for effective imaging.
Article Abstract
Visualisation of the renal arteries and image quality of intravenous DSA were evaluated in 62 patients. The left renal artery is visualised less well than overlying more frequently the right renal artery because of gas in the stomach and colon. IV DSA is not adequate for visualisation of the subsegmental arteries, and cannot be used for tumor angiography. It is not possible to prove that central venous injection technique is superior to peripheral venous injection. Patients must be carefully prepared as is necessary for the urogram. Examination is carried out using Buscopan and a compression device.

Department of Anesthesiology and Critical Care, Faculty of Medicine, Karadeniz Technical University, Trabzon, Turkey.
Objective: The agitation that can occur in patients undergoing vitreoretinal surgery on awakening from general anesthesia is a serious post-operative problem. In our study, we aimed to compare the effects of different anesthesia methods on emergence agitation in patients undergoing vitreoretinal surgery.
Method: Patients undergoing vitreoretinal surgery were divided into two groups: Total intravenous anesthesia (Group T) and inhalation anesthesia (Group D) according to the maintenance of anesthesia applied by consulting the records.
Trastuzumab-Pertuzumab Plus Eribulin or Taxane as First-Line Chemotherapy for Human Epidermal Growth Factor 2-Positive Locally Advanced/Metastatic Breast Cancer: The Randomized Noninferiority Phase III EMERALD Trial.

Department of Breast Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.
Purpose: Trastuzumab-pertuzumab (HP) plus taxane is a current standard first-line therapy for recurrent or metastatic human epidermal growth factor 2 (HER2)+ breast cancer (BC). We investigated noninferiority of eribulin to a taxane when combined with dual HER2 blockade as first-line systemic treatment for locally advanced/metastatic HER2+ BC.
Methods: In the phase III EMERALD trial (target sample size, 480; ClinicalTrials.

Department of Orthopaedic Surgery, Keio University School of Medicine, Shinjyuku, Tokyo.
Study Design: Multicenter retrospective cohort study.
Objective: To evaluate the efficacy and safety of using cement-augmented pedicle screw (CAPS) fixation only for the cephalad and caudal vertebral bodies.
Summary Of Background Data: Pedicle screw fixation is less effective in patients with low-quality bone.
Background: Lecanemab has been approved by the FDA for patients with early Alzheimer's disease (AD). NA-831 is an experimental drug that has showed a proof of safety and efficacy in Phase 2 clinical trial for patients with early Alzheimer's disease. AD patients are treated with a number of comedications not only to address cognitive impairment (standard-of-care) but also other comorbidities.
