Purpose: To examine the safety, effectiveness, and patient-perceived benefit of treatment with olanzapine for nausea and vomiting (N/V) in patients with advanced cancer.

Methods: We conducted a multicenter prospective observational study in a tertiary care setting (Trial registration number: UMIN000020493, date of registration: 2016/1/12). We measured the following: average nausea in the last 24 h using a Numeric Rating Scale (NRS: range 0-10) at baseline and day 2, patient-perceived treatment benefit (based on a 5-point verbal scale), and adverse events (AEs; using the Common Terminology Criteria for Adverse Events version 4).

The feasibility and limitation of coronary computed tomographic angiography imaging to identify coronary lipid-rich atheroma in vivo: Findings from near-infrared spectroscopy analysis.

Background: Coronary computed tomography angiography (CCTA) non-invasively visualizes lipid-rich plaque. However, this ability is not fully validated in vivo. The current study aimed to elucidate the association of CCTA features with near-infrared spectroscopy-derived lipidic plaque measure in patients with coronary artery disease.

Comparison between patient-reported and clinician-reported outcomes: Validation of the Japanese version of the Integrated Palliative care Outcome Scale for staff.

Objectives: The goal of palliative and supportive care is to improve patients' quality of life (QoL). Patient-reported outcome measures (PROMs) are the gold standard for the assessment of QoL and symptoms; however, when self-reporting is complicated, PROMs are often substituted with proxy-reported outcome measures, such as clinician-reported outcome measures. The objective of this study was to assess the validity and reliability of the Japanese version of the Integrated Palliative care Outcome Scale (IPOS) for staff (IPOS-Staff).

Combination of echocardiography and emergency endomyocardial biopsy for suspected myocarditis in the cardiovascular emergency medical care.

Myocarditis is a fatal inflammatory disease of myocardium, diagnosed with clinical and histopathological findings by endomyocardial biopsy (EMB). Myocarditis has a variety of clinical presentations and a dynamic and sometimes rapid process of severity. Echocardiography plays an important role in the management of myocarditis because it has noninvasiveness and portability.

Complexity of desire for hastened death in terminally ill cancer patients: A cluster analysis.

Objectives: The present study aims were (1) to identify the proportion of terminally ill cancer patients with desire for hastened death (DHD) receiving specialized palliative care, (2) to identify the reasons for DHD, and (3) to classify patients with DHD into some interpretable subgroups.

Methods: Advanced cancer patients admitted to 23 inpatients hospices/palliative care units in 2017 were enrolled. Data were prospectively obtained by the primarily responsible physicians.

Intravascular Lithotripsy for Vessel Preparation in Severely Calcified Coronary Arteries Prior to Stent Placement - Primary Outcomes From the Japanese Disrupt CAD IV Study.

Aim: To investigate intrapartum fetal heart rate (FHR) patterns in women with chorioamnionitis at or beyond 34 weeks of gestation in relation to neonatal outcome and to compare clinical and subclinical chorioamnionitis.

Methods: A retrospective questionnaire survey on deliveries during 2015 was conducted by the Perinatology Committee of the Japan Society of Obstetrics and Gynecology from 2016 to 2018. A total of 498 singleton births complicated by chorioamnionitis delivered at ≥34 weeks of gestation without major congenital malformations were included.

Longitudinal Evaluation of Mitral Valve Leaflet Remodeling After Acute Myocardial Infarction: Serial Quantitation of Valve Geometry Using Real-Time 3-Dimensional Echocardiography.

Background: Recent animal studies have suggested that mitral valve (MV) leaflet remodeling can occur even without significant tethering force and that the postinfarct biological reaction would contribute to the histopathologic changes of the leaflet. We serially evaluated the MV remodeling in patients with anterior and inferior acute myocardial infarction (MI), by using 2- and 3-dimensional transthoracic echocardiography. Additional histopathologic examinations were performed to assess the leaflet pathology.

Impact of Age on Gender Difference in Long-term Outcome of Patients With Acute Myocardial Infarction (from J-MINUET).

Although gender difference in long-term outcomes after acute myocardial infarction have been shown previously, impact of age on gender difference is still controversial. This study focused on the association between age and gender difference in long-term outcome. We analyzed data from 3,283 consecutive patients who were included in a prospective, nationwide, multicenter registry (Japan Registry of Acute Myocardial Infarction Diagnosed by Universal Definition) from 2012 to 2014.

Efficacy and Safety of Early Initiation of Eplerenone Treatment in Patients with Acute Heart Failure (EARLIER trial): a multicentre, randomized, double-blind, placebo-controlled trial.

Aims: A mineralocorticoid receptor antagonist (MRA) is effective in patients with chronic heart failure; however, the effects of the early initiation of an MRA in patients with acute heart failure (AHF) have not been elucidated.

Methods And Results: In this multicentre, randomized, double-blind, placebo-controlled, parallel-group study, we focused on the safety and effectiveness of the treatment with eplerenone, a selective MRA in 300 patients with AHF, that is, 149 in the eplerenone group and 151 in the placebo group in 27 Japanese institutions. The key inclusion criteria were (i) patients aged 20 years or older and (ii) those with left ventricular ejection fraction of ≤40%.

Efficacy of cryo-ablation during atrioventricular nodal reentrant tachycardia.

Because of the low atrioventricular (AV) block risk during cryo-ablation, it has become possible to treat AV nodal reentrant tachycardia (AVNRT) during arrhythmia. This study aimed to investigate the clinical outcomes of performing cryo-ablation for AVNRT during arrhythmia. Twenty-three patients with AVNRT treated by cryo-ablation during arrhythmia were enrolled.

Clinical expert consensus document on rotational atherectomy from the Japanese association of cardiovascular intervention and therapeutics.

Rotational atherectomy (RA) has been widely used for percutaneous coronary intervention (PCI) to severely calcified lesions. As compared to other countries, RA in Japan has uniquely developed with the aid of greater usage of intravascular imaging devices such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT). IVUS has been used to understand the guidewire bias and to decide appropriate burr sizes during RA, whereas OCT can also provide the thickness of calcification.

Congenital Abdominal Aortic Aneurysm in a Four Year Old Girl.

Introduction: Abdominal aortic aneurysm (AAA) in neonates, infants, and children is uncommon, usually occurring as a result of infections, connective tissue disorders, vasculitis, or iatrogenic trauma. A case of idiopathic congenital AAA, an extremely rare disease of unknown origin, is described.

Report: In March 2018, a 40 mm hypoechoic mass adjacent to the left kidney was detected incidentally by abdominal ultrasound for investigation of hypercalciuria in a four year old girl.

Relations of Augmented Systolic Annular Expansion and Leaflet/Papillary Muscle Dynamics in Late-Systolic Mitral Valve Prolapse Evaluated by Echocardiography with a Speckle Tracking Analysis.

The mechanism of systolic annular expansion in mitral valve prolapse (MVP) is not clarified. Since annular expansion is systolic outward shift of MV leaflet/chorda tissue complex at superior and outer ends, annular expansion could be related to inward (superior) shift of the complex at another inferior and inner end of the papillary muscle (PM) tip and/or systolic lengthening of the tissue complex, especially MV leaflets.MV annulus systolic expansion, PMs' systolic superior shift, and MV leaflets' systolic lengthening were evaluated by echocardiography with a speckle tracking analysis in 25 normal subjects, 25 subjects with holo-systolic MVP and 20 subjects with late-systolic MVP.

Diminished response to statins predicts the occurrence of heart failure after acute myocardial infarction.

Background: Lowering low-density lipoprotein cholesterol (LDL-C) levels using a statin is a cornerstone of preventive therapeutic management following acute myocardial infarction (AMI). In addition to its anti-atherosclerotic effects, recent studies reported a lower occurrence of heart failure (HF) under statin therapy. However, there is a wide variability in statin response.

Clinical characteristics and in-hospital outcomes in patients aged 80 years or over with cardiac troponin-positive acute myocardial infarction -J-MINUET study.

Background: The prevalence of acute myocardial infarction (AMI) in elderly people is increasing worldwide. However, their characteristics and prognosis have been rarely investigated. This study aimed to investigate the characteristics and prognosis in elderly patients with cardiac troponin-positive AMI.

Prognostic Impact of B-Type Natriuretic Peptide on Long-Term Clinical Outcomes in Patients with Non-ST-Segment Elevation Acute Myocardial Infarction Without Creatine Kinase Elevation.

Although B-type natriuretic peptide (BNP) has gradually gained recognition as an indicator in risk stratification for patients with acute myocardial infarction (AMI), the prognostic impact on long-term clinical outcomes in patients with non-ST-segment elevation acute myocardial infarction (NSTEMI) without creatine kinase (CK) elevation remains unclear.This prospective multicenter study assessed 3,283 consecutive patients with AMI admitted to 28 institutions in Japan between 2012 and 2014. We analyzed 218 patients with NSTEMI without CK elevation (NSTEMI-CK) for whom BNP was available.
