Dose-Dependent Inhibitory Effect of Rosuvastatin in Japanese Patients with Acute Myocardial Infarction on Serum Concentration of Matrix Metalloproteinases-INVITATION Trial.

Aim: Matrix metalloproteinases (MMPs) play critical roles in acute myocardial infarction (AMI). This trial was conducted to determine the potential effects of higher-dose rosuvastatin on circulating MMP levels in patients with AMI.

Methods: This was a multicenter, open-label, 1:1 randomized, parallel-group study.

Imaging-guided PCI for event suppression in Japanese acute coronary syndrome patients: community-based observational cohort registry.

Although there is accumulating evidence for the usefulness of imaging-guided percutaneous coronary intervention (PCI), there are few studies for acute coronary syndrome (ACS), and the impact of the frequency of use has not been well addressed. From the Kumamoto Intervention Conference Study; a Japanese registry comprising 17 institutions, consecutive patients undergoing successful PCI from April 2008 through March 2014 were enrolled. Subjects were divided into two groups: imaging-guided PCI and angiography-guided PCI.

Dose-dependent INhibitory effect of rosuVastatin In Japanese patienTs with Acute myocardial infarcTION on serum concentration of matrix metalloproteinases - INVITATION trial.

Background: Acute myocardial infarction (AMI) is mainly characterized by the rupture of lipid-rich vulnerable atherosclerotic plaque. The matrix metalloproteinases (MMPs) have been shown to play a critical role in inflammatory processes underlying plaque rupture. Some reports suggested statins inhibit the increased MMP levels after AMI.

Multicenter, Randomized, Double-Blinded, Placebo-Controlled Phase II Study of Serelaxin in Japanese Patients With Acute Heart Failure.

Background: Serelaxin, a recombinant form of human relaxin-2, is in development for treating acute heart failure (AHF) and a Phase II study in Japanese AHF patients was conducted.

Methods And Results: A randomized, double-blind, placebo-controlled study of serelaxin at 10 and 30 µg·kg(-1)·day(-1)continuous intravenous infusion for up to 48 h, added to standard care for Japanese AHF patients. Primary endpoints were adverse events (AEs) through Day 5, serious AEs (SAEs) through Day 14, and serelaxin pharmacokinetics.

[A case of gastric mucosal laceration due to seat belt injury].

A 69-year-old man was involved in a road traffic accident wherein his car hit a telegraph pole and turned over. He reported wearing a seatbelt and denied any injuries or pain at that time. Six hours after the accident, however, he developed melena and hematemesis.

A survival case of cardiogenic shock due to left main coronary artery myocardial infarction: successful cooperation with on-site percutaneous coronary intervention and helicopter emergency medical service.

A 54-year-old man was referred to a local hospital, located about 90 km from our hospital, with cardiogenic shock due to left main coronary artery infarction (LMCA-MI). Percutaneous coronary intervention (PCI) was performed under intra-aortic balloon pumping (IABP) support, but resulted in insufficient reperfusion and his condition worsened. The helicopter emergency medical service (HEMS) rapidly transported the patient to our hospital.

Clinical outcomes following coronary stenting in Japanese patients treated with and without proton pump inhibitor.

Background: The aim of this study was to examine the effect of proton-pump inhibitor (PPI) on clinical outcomes in Japanese patients who undergo coronary stent implantation.

Methods And Results: A total of 1,270 patients (males 915, 69 years) were enrolled and dual antiplatelet therapy of aspirin and a thienopyridine derivative was prescribed (clopidogrel 630, ticlopidine 640). Patients were divided into 2 groups treated with or without PPI.

[A case of groove pancreatitis (segmental form) presented with obstructive jaundice associated with pancreatobiliary maljunction].

A 52-year-old-man was admitted to our hospital for obstructive jaundice. Percutaneous transhepatic cholangio drainage (PTCD) and endscopic retrograde cholangiopancreatography (ERCP) were performed, and pointed out stenosis of lower common bile duct (CBD) and pancreatobiliary maljunction. Brushing cytology of this lesion was negative for malignancy.

Changes of lactate, glucose, ionized calcium and glutamate concentrations in cephalic vein blood during brain hypothermia using extracorporeal membrane oxygenation (ECMO) in a newborn infant with hypoxic-ischemic encephalopathy.

An asphyxiated infant with severe hypoxic-ischemic encephalopathy was treated by brain hypothermia using extracorporeal membrane oxygenation (ECMO). The brain hypothermia using ECMO maintained cardiopulmonary functions and stabilized brain temperatures by stably supply of the cooled blood to the brain. Moreover,we measured the levels of glucose, lactate, ionized calcium and glutamate in plasma.

Low adjusted serum ionized calcium concentration shortly after birth predicts poor outcome in neonatal hypoxic-ischemic encephalopathy.

Aim: Hypoxic-ischemic reperfusion injury causes either necrosis or apoptosis, and the influx of ionized calcium into cells is the major cause of both types of cell death. The aim of this study was to investigate whether or not the serum ionized calcium concentration in neonates with hypoxic-ischemic encephalopathy (HIE) could be used to predict their outcome.

Methods: Serum samples were obtained shortly after birth from 20 HIE neonates who had not urinated or received treatment with calcium.

Human cord blood leukocyte innate immune responses to defense collagens.

The innate immune system provides critical protection during initial infections before the generation of an appropriate adaptive (antibody or T cell mediated) immune response. These early defense mechanisms may be particularly critical for neonates in whom the adaptive immune system is not fully operational. Pattern recognition molecules target potential pathogens for destruction by the innate immune system, and likely facilitate the initiation of a pathogen-specific immune response.

Low-coherence interferometer system for the simultaneous measurement of refractive index and thickness.

We have developed a low-coherence interferometer system used for the simultaneous measurement of refractive index n and thickness t of transparent plates. Both the phase index n(p) and group index n(g) can be determined automatically in a wide thickness range of from 10 microm to a few millimeters. Two unique techniques are presented to measure n(p), n(g), and t simultaneously.
