Elevated blood pressure (BP) is the most common cause of cardiovascular disease. Salt intake has a strong influence on BP, and plasma sodium (pNa) is increased with progressive increases in salt intake. However, the associations with pNa and BP had been reported inconsistently. We evaluated the association between pNa and BP, and estimated the risks of all-cause-mortality according to pNa levels. On the basis of data collected from health checkups during 1995-2009, 97,009 adult subjects were included. Positive correlations between pNa and systolic BP, diastolic BP, and pulse pressure (PP) were noted in participants with pNa ≥138 mM/L (P<0.001). In participants aged ≥50 yr, SBP, DBP, and PP were positively associated with pNa. In participants with metabolic syndrome components, the differences in SBP and DBP according to pNa were greater (P<0.001). A cumulative incidence of mortality was increased with increasing pNa in women aged ≥50 yr during the median 4.2-yr-follow-up (P<0.001). In women, unadjusted risks for mortality were increased according to sodium levels. After adjustment, pNa ≥145 mM/L was related to mortality. The positive correlation between pNa and BP is stronger in older subjects, women, and subjects with metabolic syndrome components. The incidence and adjusted risks of mortality increase with increasing pNa in women aged ≥50 yr. 相似文献

Coronary artery problems in children usually have a significant impact on both short-term and long-term outcomes. Early and accurate diagnosis, therefore, is crucial but technically challenging due to the small size of the coronary artery, high heart rates, and limited cooperation of children. Coronary artery visibility on CT and MRI in children is considerably improved with recent technical advancements. Consequently, CT and MRI are increasingly used for evaluating various congenital and acquired coronary artery abnormalities in children, such as coronary artery anomalies, aberrant coronary artery anatomy specific to congenital heart disease, Kawasaki disease, Williams syndrome, and cardiac allograft vasculopathy. 相似文献

ObjectiveThe purpose of this study was to evaluate the clinical utility and validity of using a pupillometer to assess patients with acute brain lesions.MethodsPupillary examinations using an automated pupillometer (NeurOptics®NPi™-100 Pupillometer) were performed every 4 hours and were simultaneously assessed using the Glasgow Coma Scale (GCS) and for intracranial pressure (ICP), from admission to discharge or expire in neuro-intensive care unit (NICU). Manual pupillary examinations were also recorded for comparison. By comparing these data, we evaluated the validity of using automated pupillometers to predict clinical outcomes.ResultsThe mean values of the Neurologic Pupillary index (NPi) were different in the groups examined manually. The GCS correlated well with NPi values, especially in severe brain injury patients (GCS below 9). However, the NPi values were weakly correlated with intracranial pressure (ICP) when the ICP was lower than 30 cm H2O. The NPi value was not affected by age or intensity of illumination. In patients with a "poor" prognosis who had a Glasgow Outcome Scale (GOS) of 1 or 2, the mean initial NPi score was 0.88±1.68, whereas the value was 3.89±0.97 in patients with a "favorable" prognosis who had a GOS greater than 2 (p<0.001). For predicting clinical outcomes, the initial NPi value of 3.4 had the highest sensitivity and specificity.ConclusionAn automated pupillometer can serve as a simple and useful tool for the accurate measurement of pupillary reactivity in patients with acute brain lesions. 相似文献

Background/Aims: In patients with hepatocellular carcinoma (HCC) exceeding the Milan criteria, the recurrence rate after liver transplantation is over 50%. We investigated pretransplant factor(s) that could predict recurrence after living donor liver transplantation (LDLT) in patients with HCC exceeding the Milan criteria. Methods: Pre‐operative imaging showed that, of the 111 HCC patients who underwent LDLT between June 1995 and January 2006, 37 exceeded the Milan criteria. Clinical factors before LDLT were evaluated. Results: The 1‐ and 3‐year cumulative recurrence rates were 35 and 55% respectively. Pretransplant risk factors for HCC recurrence were large tumour size (>6 cm, P=0.001), tumour exposed to the liver surface (P=0.014) and progressive disease after pretransplant treatment (P=0.038). The 2‐year HCC recurrence rates in patients with 0, 1, 2 and 3 factors were 0% (0/4), 9% (1/16), 80% (8/10) and 100% (7/7) respectively (P<0.001). The 2‐year survival rate was significantly higher in patients with 0 or 1 factor than in patients with two or more factors (P=0.022). Conclusions: In patients with HCC exceeding the Milan criteria, the three pretransplant factors that may be useful for identifying those with high HCC recurrence potential after LDLT are tumour size >6 cm, progressive disease after pretransplant treatment and tumour exposed to the liver surface. 相似文献

[Purpose] The purpose of this study was to identify changes in the thicknesses of the
cervical flexors according to eye coordination during deep cervical flexor training.
[Subjects and Methods] Twenty normal adults were randomly selected, and during their deep
cervical flexor training and eye tracking, the thicknesses of the longus colli and the
sternocleidomastoid were measured using ultrasonic waves. [Results] The thickness of the
longus colli statistically significantly increased when deep cervical flexor training and
eye coordination were performed simultaneously. However, the thickness of the
sternocleidomastoid did not show statistically significant differences according to eye
coordination. [Conclusion] Eye coordination during deep cervical flexor training is likely
to increase the thickness of the longus colli selectively. 相似文献

[Purpose] The purpose of this study was to determine the effect of the cocontraction of
masticatory muscles during neck stabilization exercises on changes in the thickness of the
neck flexors. [Subjects and Methods] Twenty subjects performed neck stabilization only
exercise and neck stabilization exercise with simultaneous contraction of the masticatory
muscles. Changes in the thickness of the longus colli and sternocleidomastoid were then
measured by ultrasound. [Results] The thickness of the longus colli increased
significantly fallowing cocontraction of the masticatory muscles and neck stabilization
exercise, whereas the exercise method used had no significant effect on the thickness of
the sternocleidomastoid. [Conclusion] Cocontraction of the masticatory muscles during neck
stabilization exercise is helpful in increasing the thickness of longus colli muscle.Key words: Masticatory muscle, Neck stabilization exercises, Thickness of neck flexors 相似文献
