Hypoplasia of abdominal wall muscles following massive fetal persistent chylous ascites without anemia.

Abdominal wall hypoplasia is a widely known clinical finding of genetic disorders such as the prune belly syndrome. On the other hand, there are few cases of abdominal wall muscle hypoplasia associated with fetal ascites due to fetal hydrops caused by fetal anemia have been reported. We report a case of fetal chylous ascites without anemia, resulting in abdominal wall muscle hypoplasia and flabby skin.

Prevalence and distribution of coronary calcium in asymptomatic Japanese subjects in lung cancer screening computed tomography.

Background: Coronary artery calcium (CAC) is associated with a risk of coronary heart disease. The prevalence and distribution of the CAC score have been examined in Western countries, but few studies have been performed in Asia, and especially in Japan. The goal of this study was to investigate CAC scores in an asymptomatic Japanese population.

Randomized, Double-Blind, Dose-Finding, Phase II Study of Prasugrel in Japanese Patients Undergoing Elective Percutaneous Coronary Intervention.

Aim: Prasugrel is a novel platelet P2Y12 receptor blocker with a faster onset of action and greater platelet inhibition with less response variability than clopidogrel. Our objective was to determine the optimal prasugrel dose in Japanese patients undergoing elective percutaneous coronary intervention (PCI) with respect to the incidence of bleeding and platelet inhibition.

Methods: A total of 422 patients were randomly assigned to receive clopidogrel or prasugrel in two strata (standard group: ＜75 years of age and body weight ＞50 kg, n=312; high-risk group: ≥75 years of age and/or body weight ≤50 kg, n=110).

Characteristics and trends of POBA in current DES Era.

The aim of this study is to clarify the characteristics and trends of POBA in current drug-eluting stent (DES) era. We examined retrospectively the cases of POBA performed in our institute during the years from 2008 to 2012. For control, bare metal stents (BMS) and DES implantation done in 2011 were analyzed.

Adaptive servo-ventilation in cardiac function and neurohormonal status in patients with heart failure and central sleep apnea nonresponsive to continuous positive airway pressure.

Objectives: The aim of this study was to investigate whether effective suppression of central sleep apnea (CSA) by adaptive servo-ventilation (ASV) improves underlying cardiac dysfunction among patients with heart failure (HF) in whom CSA was not effectively suppressed by continuous positive airway pressure (CPAP).

Background: The presence of CSA in HF is associated with a poor prognosis, whereas CPAP treatment improves HF. However, in a large-scale trial, CPAP failed to improve survival, probably due to insufficient CSA suppression.

Craniofacial anatomical risk factors in men with obstructive sleep apnea and heart failure: a pilot study.

Purpose: Obstructive sleep apnea (OSA) is complicated with heart failure (HF); however, the reason for this is not well understood. Craniofacial anatomic risk factors may contribute to OSA pathogenesis in HF patients. However, there are no data about cephalometric findings among OSA patients with HF.

Deep vein thrombosis risk stratification.

Pulmonary thromboembolism (PTE) is a life-threatening disease which always presents in patients with deep vein thrombosis (DVT). There are few statements in guidelines regarding indications for anticoagulation based on the location of DVT. We investigated whether the relative risk of PTE depends on thrombus location and bleeding complications with anticoagulation therapy.

Giant coronary artery aneurysms associated with Kawasaki disease detected on whole-heart magnetic resonance coronary angiographic screening.

Kawasaki disease (KD) is one of the most important causes of coronary artery aneurysms in children and young adults. However, the natural course of the disease and the patient prognosis remain obscure. A 72-year-old asymptomatic man with undiagnosed KD underwent whole-heart magnetic resonance coronary angiography during a health checkup.

Effects of obstructive sleep apnea and its treatment on signal-averaged P-wave duration in men.

Background: Prolonged P-wave duration, indicating atrial conduction delay, is a potent precursor of atrial fibrillation. Obstructive sleep apnea (OSA) is a risk factor for atrial fibrillation development. We investigated the association of P-wave duration with OSA and its treatment.

Peri-stent contrast staining and very late stent thrombosis after sirolimus-eluting stent implantation: an observation from the RESTART (REgistry of Stent Thrombosis for review And Re-evaluaTion) angiographic substudy.

Aims: The aim of the study was to clarify the angiographic characteristics of stent thrombosis (ST) in relation to sirolimus-eluting stents (SES).

Methods And Results: RESTART is a Japanese registry of SES-associated ST. As an angiographic substudy, coronary angiograms at baseline, at six to 12 months and at the time of ST were analysed.

Impact of intensive lipid lowering on lipid profiles over time and tolerability in stable coronary artery disease: insights from a subanalysis of the coronary atherosclerosis study measuring effects of rosuvastatin using intravascular ultrasound in Japanese subjects (COSMOS).

Background: Previous studies have demonstrated that intensive lipid lowering using rosuvastatin results in regression of coronary plaques. However, few data exist regarding lipid profiles over time, drug tolerability, and the effects of prior use of lipid lowering agents in patients on rosuvastatin treatment. Therefore, we studied these matters in a subanalysis of the Coronary Atherosclerosis Study Measuring Effects of Rosuvastatin Using Intravascular Ultrasound in Japanese Subjects (COSMOS).

Relationship between atrial conduction delay and obstructive sleep apnea.

Prolonged P-wave duration, indicating atrial conduction delay, is a marker of left atrial abnormality and is reported as a potent precursor of atrial fibrillation (AF). Several studies have shown that obstructive sleep apnea (OSA) is associated with AF. We evaluated the relationship between OSA and prolonged P-wave duration.

High HbA1c levels correlate with reduced plaque regression during statin treatment in patients with stable coronary artery disease: results of the coronary atherosclerosis study measuring effects of rosuvastatin using intravascular ultrasound in Japanese subjects (COSMOS).

Background: The incidence of cardiac events is higher in patients with diabetes than in people without diabetes. The Coronary Atherosclerosis Study Measuring Effects of Rosuvastatin Using Intravascular Ultrasound in Japanese Subjects (COSMOS) demonstrated significant plaque regression in Japanese patients with chronic coronary disease after 76 weeks of rosuvastatin (2.5 mg once daily, up-titrated to a maximum of 20 mg/day to achieve LDL cholesterol <80 mg/dl).

Clinically evident polyvascular disease and regression of coronary atherosclerosis after intensive statin therapy in patients with acute coronary syndrome: serial intravascular ultrasound from the Japanese assessment of pitavastatin and atorvastatin in acute coronary syndrome (JAPAN-ACS) trial.

Aim: To clarify whether the effects of statin treatment on plaque regression vary according to the presence or absence of polyvascular disease (PVD) in patients with acute coronary syndrome (ACS).

Methods: 307 patients with ACS who underwent percutaneous coronary intervention for the culprit lesion at 33 centers were treated with atorvastatin or pitavastatin. Noncoronary atherosclerosis was defined as coexistent, clinically recognized arterial disease other than coronary artery disease (CAD) (cerebral, aortic, or lower extremity).

Effects of olmesartan on blood pressure and insulin resistance in hypertensive patients with sleep-disordered breathing.

The increased risk of cardiovascular morbidity and mortality among patients with sleep-disordered breathing (SDB) has been linked to arterial hypertension and insulin resistance. However, an effective antihypertensive agent for patients with SDB has not been identified. We investigated the effect of the angiotensin II subtype 1 receptor blocker olmesartan in hypertensive patients with SDB.

Plasma pentraxin3 and arterial stiffness in men with obstructive sleep apnea.

Background: Obstructive sleep apnea (OSA) induces inflammation and vascular damage that might contribute to an increased risk of cardiovascular disease (CVD). However, the mechanisms linking OSA and CVD are not fully understood. Pentraxin3 may play a significant role in vascular inflammation and damage.

A quantitative coronary angiography-matched comparison between a prospective randomised multicentre cutting balloon angioplasty and bare metal stent trial (REDUCE III) and the Rapamycin-Eluting Stent Evaluation At Rotterdam Cardiology Hospital (RESEARCH) study.

Aims: There remains significant concern about the long-term safety of drug-eluting stents (DES). However, bare metal stents (BMS) have been used safely for over two decades. There is therefore a pressing need to explore alternative strategies for reducing restenosis with BMS.

More intensive lipid lowering is associated with regression of coronary atherosclerosis in diabetic patients with acute coronary syndrome--sub-analysis of JAPAN-ACS study.

Aim: We have shown that aggressive lipid lowering by pitavastatin and atorvastatin results in marked regression of atherosclerotic coronary lesions after acute coronary syndrome (ACS). The purpose of this study was to address the association of lipid levels after statin therapy with regression of atherosclerotic coronary lesions and major cardiovascular events in patients after ACS.

Methods: JAPAN-ACS is a prospective, randomized open-label study performed at 33 centers in Japan.

Comparisons of baseline demographics, clinical presentation, and long-term outcome among patients with early, late, and very late stent thrombosis of sirolimus-eluting stents: Observations from the Registry of Stent Thrombosis for Review and Reevaluation (RESTART).

Background: Stent thrombosis (ST) after sirolimus-eluting stent implantation has not yet been adequately characterized, mainly because of its low incidence.

Methods And Results: The Registry of Stent Thrombosis for Review and Reevaluation (RESTART) is a Japanese nationwide registry of sirolimus-eluting stent-associated ST comprising 611 patients with definite ST (early [within 30 days; EST], 322 patients; late [between 31 and 365 days; LST], 105 patients; and very late [>1 year; VLST], 184 patients). Baseline demographics, clinical presentation, and long-term outcome of sirolimus-eluting stent-associated ST were compared among patients with EST, LST, and VLST.

Production of butyl-biodiesel using lipase physically-adsorbed onto electrospun polyacrylonitrile fibers.

Butyl-biodiesel production using electrospun polyacrylonitrile fibers with Pseudomonas cepacia lipase immobilized through physical adsorption was studied. About 80% conversion to butyl-biodiesel was achieved after 24h by suspending the catalyst at 2.4 mg/mL in a mixture of rapeseed oil and n-butanol at a molar ratio of 1:3, containing water at 8000 ppm at 40 degrees C.

Diabetes mellitus is a major negative determinant of coronary plaque regression during statin therapy in patients with acute coronary syndrome--serial intravascular ultrasound observations from the Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome Trial (the JAPAN-ACS Trial).

Background: The Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome (JAPAN-ACS) trial has found that early aggressive statin therapy in patients with acute coronary syndrome (ACS) significantly reduces the plaque volume (PV) of non-culprit coronary lesions. The purpose of the present study was to evaluate clinical factors that have an impact on plaque regression using statin therapy.

Methods And Results: Serial intravascular ultrasound observations over 8-12 months were performed in 252 ACS patients receiving pitavastatin or atorvastatin.

Immobilization of Pseudomonas cepacia lipase onto electrospun polyacrylonitrile fibers through physical adsorption and application to transesterification in nonaqueous solvent.

The lipase of Pseudomonas cepacia was immobilized onto electrospun polyacrylonitrile (PAN) fibers and used for the conversion of (S)-glycidol with vinyl n-butyrate to glycidyl n-butyrate in isooctane. The rate of reaction with the adsorbed lipase was 23-fold higher than the initial material. After 10 recyclings, the initial reaction rate was 80% of the original rate.

Infective endocarditis complicated with splenic abscess successfully treated with splenectomy followed by double valve replacement.

Splenic abscess (SA) is a rare complication of infective endocarditis (IE). A successful outcome lies with a choice between medical and surgical treatments. However, there is still insufficient evidence in the decision-making process.
