Usefulness of color Doppler and strain elastography adjunctive to B-mode ultrasonography in the diagnosis of non-mass abnormalities of the breast: results of the BC-07 multicenter study of 385 cases.

Purpose: The concept of non-mass abnormalities of the breast has been employed in Japan for approximately 20 years. Although B-mode findings are classified as non-mass abnormalities, the usefulness of adding color Doppler ultrasonography (US) and strain elastography to B-mode US is unclear. Therefore, we conducted a multicenter study (JABTS BC-07) to establish the diagnostic criteria for breast US, including color Doppler and elastography, for non-mass abnormalities of the breast and verify their diagnostic usefulness.

Study protocol and baseline characteristics of newly induced dialysis patients: a prospective multi-center cohort study with a biological sample bank, the Ibaraki Dialysis Initiation Cohort (iDIC) study.

Background: Patients with end-stage kidney disease (ESKD) face higher risks of life-threatening events including cardiovascular disease. Various risk factors are identified as agents influencing the life prognosis of ESKD patients. Herein, we evaluated the risk factors related to the outcomes of Japanese patients with dialysis induction.

[Neuroendocrine Differentiation of Prostate Cancer : A Case Report].

A 79-year-old man underwent a transrectal prostate needle biopsy with a prostate-specific antigen (PSA) level of 12.0 ng/ml. He was diagnosed with adenocarcinoma (Gleason score 4＋3, cT3aN0M0) and underwent radiation therapy.

Utility of B-Mode, Color Doppler and Elastography in the Diagnosis of Breast Cancer: Results of the CD-CONFIRM Multicenter Study of 1351 Breast Solid Masses.

The usefulness of color Doppler ultrasound (CD) in distinguishing between benign and malignant breast lesions remains controversial. Our prior study, the Japan Association of Breast and Thyroid Sonology (JABTS) BC-04 study (malignant: 839, benign: 569), found CD was useful in breast cancer diagnosis, and we developed CD diagnostic criteria. The first aim of the current study (the CD-CONFIRM study) was to evaluate the usefulness of the CD diagnostic criteria.

Osteopontin silencing attenuates bleomycin-induced murine pulmonary fibrosis by regulating epithelial-mesenchymal transition.

Idiopathic pulmonary fibrosis (IPF) is the most common and most deadly form of interstitial lung disease. Osteopontin (OPN), a matricellular protein with proinflammatory and profibrotic properties, plays a major role in several fibrotic diseases, including IPF; OPN is highly upregulated in patients' lung samples. In this study, we knocked down OPN in a bleomycin (BLM)-induced pulmonary fibrosis (PF) mouse model using small interfering RNA (siRNA) to determine whether the use of OPN siRNA is an effective therapeutic strategy for IPF.

B-mode ultrasound diagnostic flowchart for solid breast masses: JABTS BC-01 study.

Purpose: Breast ultrasound has been widely used as an essential examination for diagnosing breast cancer. However, standardized diagnostic criteria are as yet lacking. This study aimed to develop a simple diagnostic flowchart for beginners learning breast ultrasonography.

Features predicting treatment failure in pediatric acute otitis media.

Objectives: To facilitate better antibiotic stewardship, we conducted this clinical trial to identify the prognostic features of treatment failure in pediatric acute otitis media (AOM).

Study: Design: This is a randomized, parallel-group, open-label, comparative clinical trial.

Subjects And Methods: Children with AOM and aged between 1 month and 5 years were enrolled.

Male breast metastasis of ureteral cancer: a case report.

Background: Breast metastasis from extra-mammary primary tumors is extremely rare. We recently experienced a rare case of a male breast metastasis of ureteral cancer and will provide a case report.

Case Presentation: A 74-year-old man developed a ureteral cancer and underwent left nephroureterectomy with lymph node dissection.

Paravesical space arteriovenous malformation as a specific subgroup of pelvic vascular anomaly: a case series and review of literature.

Treatment of pelvic arteriovenous malformations (AVMs) is frequently challenging because of the complex structures and anatomical diversity among cases. We present a case series of six patients with pelvic AVMs. All patients had a similar anatomical structure consisting of multiple feeders from the unilateral internal iliac artery, collecting into a dilated venous sac in the unilateral paravesical space and draining into a single outflow, eventually joining the pre-prostatic vein or internal iliac vein.

Multicenter Prospective Study of Color Doppler Ultrasound for Breast Masses: Utility of Our Color Doppler Method.

The use of color Doppler ultrasound (CD) for distinguishing between benign and malignant breast lesions remains controversial. This study (JABTS BC-04 study) was aimed at confirming the usefulness of our CD diagnostic criteria. We evaluated ultrasound images of 1408 solid breast masses from 16 institutions in Japan (malignant: 839, benign: 569).

Cefotaxime-non-susceptibility of Haemophilus influenzae induced by additional amino acid substitutions of G555E and Y557H in altered penicillin-binding protein 3.

Cefotaxime-non-susceptible Haemophilus influenzae has rarely been isolated from clinical specimens. Although several reports have shown that amino acid (AA) alteration in penicillin-binding protein 3 (PBP3), encoded by the ftsI gene, reduces activity of cefotaxime, precise mechanisms conferring the non-susceptibility have been unclear. We analyzed the ftsI gene of two clinically isolated cefotaxime-non-susceptible H.

Pharmacokinetics and Safety After a Single Dose of Imarikiren in Subjects with Renal or Hepatic Impairment.

Background And Objective: Imarikiren hydrochloride (TAK-272; SCO-272) is a novel direct renin inhibitor. The objective of this study was to determine the effects of renal impairment (RI) or hepatic impairment (HI) on the pharmacokinetics and safety of imarikiren.

Methods: This phase I, open-label, parallel-group comparative study evaluated the pharmacokinetics and safety of a single 40 mg oral dose of imarikiren in RI [mild, moderate, severe, or end-stage renal disease (ESRD), and on hemodialysis] or HI (mild or moderate) subjects compared with subjects with normal renal or hepatic function.

Impact of voglibose on the pharmacokinetics of dapagliflozin in Japanese patients with type 2 diabetes.

Introduction: Dapagliflozin is an orally administered selective sodium-glucose cotransporter 2 (SGLT2) inhibitor under development for the treatment of type 2 diabetes mellitus (T2DM). Dapagliflozin lowers blood glucose through a reduction in renal glucose reabsorption. This study was performed to assess the effect of the oral antidiabetic agent voglibose [0.
