BACKGROUND It is still not clear which factors are associated with left ventricular mass index (LVMI) in chronic kidney disease (CKD) patients, based on the patient's physical and biochemical parameters at the time of echocardiography. The objective of the present study was to identify factors associated with LVMI in CKD patients (predialysis patients),(More)
It is well known that obesity and insulin resistance are closely related to the development of type 2 diabetes. However, the exact pathogenic mechanism underlying the insulin resistance in renal disease has not been clarified. The purpose of the present study was to clarify the contribution of abdominal (visceral and subcutaneous) fat accumulation to(More)
To examine the cardiovascular response to prostaglandin E1 infusion, we observed hemodynamic changes including left ventricular diameter (an ultrasonic crystal pair) during PGE1-induced hypotension in anesthetized open-chest dogs. Left ventricular contractility was assessed primarily by measuring the slope of the left ventricular end-systolic(More)
A 76-year-old woman presented to a clinic with fever and loss of body weight. Abdominal echogram showed bilateral adrenal swelling (left adrenal 90x80 mm, right adrenal 50x20 mm) and she was admitted to the hospital for further examination. A tumor was also found inside nasal cavity by enhanced computed tomography (CT), and abnormal uptake in the nasal(More)
Hemodialysis (HD) patients frequently have an elevated left ventricular mass index (LVMI). Currently, left ventricular (LV) hypertrophy and dysfunction are considered to be the strongest predictors of cardiovascular mortality in dialysis patients. The objectives of the present study are to investigate the factors associated with elevated LVMI and to discuss(More)
To test whether acute volume expansion can normalize orthostatic intolerance and autonomic tone after prolonged bed rest (BR), 23 men were subjected to 20 days BR. Left ventricular (LV) echocardiography was performed during the lower body negative pressure (LBNP) test before and after BR with and without preceding rapid infusion of saline (1,500 ml/30 min).(More)
BACKGROUND Echocardiography is widely used for the evaluation of cardiac structures and function. The prognostic value of assessment of left cardiac atrium (LA) size in peritoneal dialysis (PD) patients is still unclear. The objective of the present study is to investigate prospectively a longitudinal monitoring of echocardiography parameters after start of(More)
BACKGROUND It is recommended that arteriovenous fistula (AVF) blood flow should be more than 425 ml/min before cannulation. However, the relationship between preoperative radial artery flow (RAF) and postoperative AVF blood flow has still not been examined. METHODS Sixty-one patients with end-stage kidney disease (ESKD) were examined. They had an AVF(More)
BACKGROUND It is important to prevent development of the pressure ulcers in patients undergoing lengthy surgery, particularly at areas of skin overlying bony prominences. This study was designed to investigate distribution of the interface pressure (IP) over the body area (from the head to pelvic area) in supine adults and also evaluate the ability of a(More)
AIM Vascular dementia may be referred to as "treatable dementia" because its development and progress can be inhibited by intervention in the early stage. In particular, cerebral white matter lesions are readily encountered the clinical setting. In this study, we aimed to clarify the phenomenon and symptoms of patients with mild cognitive impairment (MCI)(More)
