There have been numerous studies of the relationship between intracerebral hemorrhage (ICH) and meteorological conditions, but their conclusions have been inconsistent. Poor discrimination of ICH subtypes (primary or secondary) may have obscured the conclusions. Although most studies have analyzed seasonal or monthly variation, daily meteorological data are(More)
BACKGROUND AND PURPOSE The association between elevated blood pressure (BP) and hematoma enlargement in acute intracerebral hemorrhage (ICH) has not been clarified. We investigated the association between maximum systolic BP (SBP) and hematoma enlargement, measuring SBP between a baseline and a second CT scan in patients with hypertensive ICH. METHODS We(More)
OBJECT Although the mechanisms underlying neurocognitive changes after carotid endarterectomy (CEA) are poorly understood, intraoperative ischemia and postoperative hemodynamic changes may play a role. METHODS Data from 81 patients who underwent unilateral CEA with routine shunt use for carotid artery stenosis were retrospectively evaluated. These(More)
OBJECT The mechanisms underlying neurocognitive changes after surgical clipping of unruptured intracranial aneurysms (UIAs) are poorly understood. The aim of this study was to investigate factors that determine postoperative cognitive decline after UIA surgery. METHODS Data from 109 patients who underwent surgical clipping of a UIA were retrospectively(More)
OBJECTIVE We assessed the cross-sectional association between sleep duration and untreated diabetes in Japanese men. METHODS Participants included 20,744 men aged 30-64 years who first visited the general hospital in Tokyo for routine health assessments during 2003-2007. Untreated diabetes was defined as not being under diabetes treatment and fasting(More)
OBJECTIVES To examine whether a lower hematocrit was associated with a lower prostate-specific antigen (PSA), when stratifying by body mass index (BMI) in healthy men. PSA test is widely used in screening for prostate cancer. Many studies have found that PSA levels inversely correlate with BMI. It remains unclear whether hemodilution causes this inverse(More)
Subarachnoid haemorrhage (SAH) patients in Fisher group 3 have a high risk of vasospasm and chronic hydrocephalus. We have provided cisternal irrigation combined with a head-shaking method for preventing vasospasm in SAH patients. We investigated 76 SAH patients in Fisher group 3 who received cisternal irrigation with head-shaking to evaluate the(More)
Total TIMP-1 concentration in whole saliva of periodontally diseased subjects, 137 +/- 67 ng/ml (mean +/- SD), was clearly lower (p < 0.001) than that of clinically healthy subjects, 273 +/- 145, and that of edentulous subjects, 332 +/- 121. On the contrary, both active [1.58 +/- 0.35 units/ml (mean +/- SD)] and total (2.08 +/- 0.25) collagenase activities(More)
INTRODUCTION Timely access to acute medical treatment can be critical for patients suffering from severe stroke. Little information is available about the impact of prehospital delays on the clinical conditions of stroke patients, but it is possible that prehospital delays lead to neurological deterioration. The aim of this study was to examine the impact(More)
Informal care by family members still plays an important role in home care after acute stroke. This study determined the clinical and demographic factors, such as family structure, that predict discharge to home and length of hospital stay (LOS) after acute stroke hospitalization. We reviewed the sex, age, family structure before stroke, type of stroke,(More)
