OBJECTIVE To evaluate the relationship between frozen-thawed single blastocyst transfer (BT) and maternal and neonatal outcomes of pregnancy. DESIGN Retrospective analysis. SETTING Japanese nationwide registry of assisted reproductive technology (ART) with mandatory reporting for all ART clinics in Japan. PATIENT(S) Registered from 2008 through 2010(More)
BACKGROUND Cardiovascular disease is the leading cause of mortality in patients with kidney failure treated with hemodialysis (HD). Although angiotensin receptor blockers (ARBs) reduce cardiovascular disease (CVD) events in patients with diabetes and chronic kidney disease, their effect in patients with kidney failure on HD therapy is not known.

OBJECTIVE To evaluate the implications of assisted reproductive technologies (ART) on neonatal birth weight. DESIGN A retrospective study using analysis of covariance and multiple logistic regression analysis of the Japanese ART registry. SETTING Japanese institutions providing ART treatment. PATIENT(S) A total of 25,777 singleton neonates reaching(More)
OBJECTIVE Early hematoma expansion is a known cause of morbidity and mortality in patients with intracerebral hemorrhage (ICH). The goal of this study was to identify clinical predictors of ICH growth in the acute stage. MATERIALS AND METHODS We studied 201 patients with acute (<6 h) deep ganglionic ICH. Patients underwent CT scan at baseline and hematoma(More)
To assess the incidence of monozygotic twinning (MZT) among cases undergoing assisted reproductive technology (ART) treatment. We performed a retrospective observational study and analyzed the data of patients who were registered in the national ART registry system of Japan from January to December 2010; only the data of patients with single embryo transfer(More)
INTRODUCTION Allergic rhinitis and asthma are often comorbid, and allergic rhinitis has been shown to be a risk factor for asthma in adults and children. Recently, the prevalence of allergic rhinitis among bronchial asthma (BA) patients was reported to be 67.3% in Japan. However, seasonal variation in the prevalence of rhinitis in Japan remains unclear. (More)
Blunt cerebrovascular injury (BCVI) is known to be a potentially fatal complication of cervical spine injury (CSI). Methods for screening the appropriate population remain to be elucidated, especially in Japan. This retrospective study was conducted to predict the risk factors relevant to BCVIs. Among 92 patients with CSI transferred to our institution from(More)
OBJECTIVE CT-diagnosed emphysema is associated with poor prognosis in chronic obstructive pulmonary disease (COPD). Its clinical impacts on prognoses of asthma with chronic airflow obstruction (CAO) are not well known. We sought to compare mortalities and prognostic factors in COPD and asthma with CAO by the presence or absence of CT-diagnosed emphysema. (More)
OBJECTIVE To investigate the positive rate for the Cochlin tomo-protein (CTP: an inner ear-specific protein) detection test among patients with inner ear-related clinical manifestations and evaluate the clinical characteristics of definite perilymphatic fistula (PLF). METHODS We have performed an ELISA-based CTP detection test using middle ear lavage(More)
Objective It is difficult to compare directly the practical effects of lifestyle modifications and antihypertensive medications on reducing cardiovascular disease (CVD). The purpose of this study was to compare the hypothetical potential of lifestyle modifications with that of antihypertensive medications in reducing CVD in an aging society using a success(More)
