RESUMO
OBJECTIVES: Despite evidence of breast cancer screening efficacy, the screening rate has remained less than 50% in Japan. This study aimed to evaluate the effect of an environmental approach offering on-site mammography in workplaces. METHODS: Supermarket stores were randomly assigned into two groups, the intervention group (leaflet and mammography) and the control group (leaflet). From May to July 2018, participants in the intervention group were given a leaflet informing them of the subsidies for breast cancer screening and offered the opportunity to have mammography in their workplaces. Participants in the control group were given the same leaflet, but had to arrange their own screening outside the workplace. The primary outcome was the breast cancer screening rate in 2018. The odds ratio (OR) and 95% confidence interval (CI) for having screening in the intervention group compared with the control group were estimated using multilevel logistic regression. RESULTS: We analyzed data from 1624 participants (mean age 53 years) from 25 supermarket stores (intervention: 8 stores, control: 17 stores). Among participants who had not attended screening in the previous year, the screening rate was 7% in the control group and 53% in the intervention group, with an adjusted OR (95% CI) of 14.22 (8.97-22.54). The effect was greater in those who had never attended screening before. CONCLUSION: In a worksite-based cluster randomized controlled trial in Japanese supermarket stores, an environmental approach offering mammography in workplaces substantially increased the breast cancer screening rate within 1 year (UMIN000030465).

Although metabolic syndrome, including visceral fat accumulation, causes kidney and cardiovascular diseases, the impact of visceral fat accumulation on mild decreased renal function remains unclear. This study examines the association between visceral fat area (VFA) measured by bioimpedance methods and the estimated glomerular filtration rate based on serum cystatin C (eGFRcys) in the Japanese urban population. This community-based cross-sectional study enrolled 952 individuals (287 men, 665 women) who participated in the second follow-up survey of the Kobe Orthopedic and Biomedical Epidemiological (KOBE) study. We compared the multivariate-adjusted means of eGFRcys among VFA quartile groups by gender using the analysis of covariance. Models were adjusted for age, high blood pressure, hypercholesterolemia, glucose intolerance, smoking, and alcohol use, and further adjusted for body mass index (BMI). The highest VFA quartile group had lower eGFRcys than the lowest VFA quartile group after adjusted for cardiometabolic risk factors, except for BMI (93.1 [95% confidence interval (CI), 90.1-96.2] vs. 82.1 [95% CI, 79.1-85.0] in men and 95.8 [95% CI, 94.1-97.5] vs. 89.4 [95% CI, 87.8-90.9] in women). Moreover, further adjustment for BMI revealed a similar result in men (93.5 [95% CI, 89.8-97.2] vs. 81.6 [95% CI, 77.9-85.3]), while no significant association was found in women. This study suggests a significant association between increased VFA levels and lower eGFRcys levels independent of cardiometabolic risk factors, such as glucose intolerance and hypercholesterolemia in men and women, as well as independent of BMI in men.

Disproportionately enlarged subarachnoid space hydrocephalus (DESH) is the characteristic feature of idiopathic normal pressure hydrocephalus. We aimed to characterize the prevalence, development, and association of DESH to cognitive deficit in a large population. We reviewed the data of 1384 subjects eligible for the present study among 1590 participants who underwent magnetic resonance imaging (MRI) in the Ohasama Study, a population-based study in Ohasama, Japan. The participants with Mini-Mental State Examination (MMSE) score < = 25 were assumed to have cognitive deficit and DESH was evaluated by reviewing the MRIs. We assessed the association between DESH, Evans index (EI), and cognitive deficit using multivariate logistic regression models adjusted for relevant confounders. Furthermore, we evaluated the new development of DESH and the deterioration of cognitive function in the participants with DESH. There were nine participants with DESH (0.65%), seven of whom showed cognitive deficit. DESH was significantly associated with cognitive deficit in multivariate regression analyses (odds ratio; 8.50 [95% confidence interval: 1.61-44.88]). In the 669 participants who underwent follow-up MRI, we found four participants newly presenting with DESH; the development of DESH was observed before/after the presence of EI > 0.3. We also found two participants with existing DESH showing no remarkable worsening in MMSE and EI. The present study demonstrated a positive association between the presence of DESH and cognitive deficit. DESH can develop independently of EI > 0.3, and ventricular enlargement in combination with DESH may be an important factor in the worsening of cognitive deficit.

The present study sought to clarify if being conscious of water intake (CWI) is associated with sufficient non-alcohol drink (NAD) intake. We used data of healthy participants without diabetes, aged 40-74 years, in the Kobe Orthopedic and Biomedical Epidemiologic (KOBE) study. The association between being CWI and NAD intake was evaluated by multivariate linear regression analyses after adjusting for age, sex, surveyed months (seasons), alcohol drinking, health-awareness life habits, socioeconomic factors, serum osmolarity, estimated daily salt intake, and reasons for NAD intake. Among 988 (698 women and 290 men) participants eligible for the present analyses, 644 participants (65.2%) were CWI and 344 participants (34.8%) were not CWI (non-CWI). The most popular reason for being CWI was to avoid heat stroke in summer and to prevent ischemic cerebral stroke in winter. The CWI group took more NAD, especially decaffeinated beverages, than the non-CWI group (1846.7 ± 675.1 mL/day vs. 1478.0 ± 636.3 ml/day, p < 0.001). There was a significant association between being CWI and NAD intake in multivariate linear regression analyses ever after adjusting for the relevant variables (ß = 318.1, p < 0.001). These findings demonstrated CWI, regardless of the reasons and the seasons, was associated with high NAD intake in Japanese healthy population.

BACKGROUND: While water intake is frequently recommended to prevent cerebral infarction (CI), only few studies have been published on this topic. OBJECTIVES: This study retrospectively estimated the daily non-alcohol drink (NAD) intake in CI patients before CI onset and compared it with NAD in healthy subjects. METHODS: We performed a cross-sectional study on CI patients in 3 hospitals and healthy subjects in the Kobe Orthopedic and Biomedical Epidemiologic (KOBE) study. Data from 1,287 subjects (274 CI patients and 1,013 healthy subjects) were used for the analyses. By dividing the CI patients into "increased", "unchanged", and "decreased" groups according to their current NAD intake, we compared the NAD intake between these 3 groups and healthy subjects by analyses of covariance and the post hoc test, adjusting for sex, age, surveyed month, body mass index, alcohol drinking history, and smoking history. Under the assumption that the NAD intake in the "unchanged" group was equal to the NAD intake before CI onset, the OR of less NAD intake for CI adjusting for the relevant variables in the "unchanged" group and the healthy subjects was calculated; the cut-off point was chosen using Youden's index. RESULTS: The mean age (mean ± SD) of the participants was 62.8 ± 9.3 years. One hundred and fifty-one patients (36 women) were included in the "increased" group; 105 (30 women), in the "unchanged" group; 18 (2 women), in the "decreased" group; and 1,013 (706 women), in the "healthy" group. The mean NAD intake was 1,702.5 ± 670.2 mL in the "increased" group, 1,494.2 ± 611.2 mL in the "unchanged" group, 1,268.0 ± 596.1 mL in the "decreased" group, and 1,720.6 ± 686.0 mL in the "healthy" group. After adjusting for the relevant variables, a significant difference in NAD intake between the groups was observed (F = 6.1, p < 0.001), and a post hoc test demonstrated significant differences (p < 0.05) in NAD intake between the "healthy" and "unchanged" groups, and between the "increased" and "unchanged" groups. The OR of less NAD intake (<1,570 mL/day, chosen using Youden's index) for CI was 2.48 (95% CI 1.52-4.07). CONCLUSION: This study showed that daily NAD intake before CI onset in CI patients was less than that in healthy persons, indicating that sufficient intake of NAD may be protective for CI.

BACKGROUND: Although several epidemiological studies have suggested that high serum uric acid (SUA) levels are related to a decline in kidney function, only a few studies have investigated using cystatin C to calculate estimated glomerular filtration rate (eGFR). We aimed to clarify the relationship between SUA levels and kidney function assessed by cystatin C in a Japanese general community population without chronic kidney disease (CKD). METHODS: We conducted a community-based cross-sectional study that included 1086 healthy participants, aged 40-74 years, without CKD and not undergoing treatment of hyperuricemia, who had participated in the baseline survey of the Kobe Orthopedic and Biomedical Epidemiological (KOBE) study. The preconditions for participation in this study were no past histories of cardiovascular disease or cancer, and not undergoing treatment for diabetes, hypertension, or dyslipidemia. We classified the participants into quartiles stratified by sex according to their SUA level and then examined the relationship with eGFR. The odds ratios for having a low eGFR, defined as the lowest quartile of eGFR (i.e., ≤78.4 mL/min/1. 73m2) was estimated according to SUA quartiles (men, Q1 ≤ 5.0, Q2 5.1-5.9, Q3 6.0-6.6, and Q4 ≥ 6.7; women, Q1 ≤ 3.8, Q2 3.9-4.3, Q3 4.4-4.9, and Q4 ≥ 5.0 mg/dL) after adjustment for age, body mass index, systolic blood pressure, HbA1c, high and low density lipoprotein cholesterol, and smoking and drinking habits. The adjusted mean of each quartile was also calculated. RESULTS: Multivariable-adjusted means of eGFR showed a graded decrease in higher SUA quartiles (men, Q1 90.5, Q2 88.0, Q3 83.5, and Q4 82.0; women, Q1 95.7, Q2 91.3, Q3 89.2, and Q4 86.7). In addition, the multivariable-adjusted odds ratios for having a lower eGFR (95% confidence interval) for each SUA quartile compared with Q1 was Q2 2.29 (0.98, 5.35), Q3 4.94 (2.04, 11.97), and Q4 8.01 (3.20, 20.04) for men, and was Q2 2.20 (1.12, 4.32), Q3 2.68 (1.39, 5.20), and Q4 4.96 (2.62, 9.41) for women. CONCLUSIONS: There was a graded inverse relationship between mild elevations in SUA levels and eGFR assessed by cystatin C in an apparently healthy Japanese population without CKD. This association was similar in both men and women.

The purpose of this study was to investigate the relationship between the frequency of outpatient visits and hypertension control as determined from health insurance records. This 9-year cohort study in Japan was based on 518 participants with hypertension who underwent health checkups in 2004. Participants were aged 35-56 years and none had a history of cardiovascular or cerebrovascular disease. All were covered by the same employee health insurer. Mean annual outpatient visit days at a hospital/clinic during the 9-year period were classified within four quartiles (Q1, Q2, Q3, Q4). Uncontrolled hypertension was defined as a systolic blood pressure (BP) ⩾140 mm Hg and a diastolic BP ⩾90 mm Hg. Logistic regression analysis was used to estimate the multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the prevalence of uncontrolled hypertension in groups Q1, Q2 and Q3 vs. Q4. The median (25th-75th percentile) annual outpatient visit days was 9.4 (4.0-15.5). Uncontrolled hypertension was observed in 62.4% of the participants in 2013. The multivariable-adjusted ORs and 95% CIs for uncontrolled hypertension in Q1, Q2 and Q3 vs. Q4 were 4.03 (2.28-7.12), 1.67 (0.99-2.81) and 1.44 (0.86-2.41), respectively. Uncontrolled hypertension increased significantly as the number of outpatient visits decreased (P for trend <0.001). This tendency was maintained when participants taking antihypertensive agents at baseline were excluded. Our study showed an inverse relationship between outpatient visit frequency and uncontrolled hypertension.

Individuals with an inactive acetaldehyde dehydrogenase 2 have an. elevated level of serum acetaldehyde after drinking alcohol, and this may cause an alcohol flushing response with symptoms such as facial flushing, tachycardia, headache, and nausea. Recent studies have suggested that the flushing response influences the association between alcohol consumption and various health-related outcomes. In the present study, we investigated the impact of the flushing response on the relationship between alcohol consumption and serum y -GTP levels in Japanese drinkers. We conducted a cross-sectional study of 521 Japanese drinkers (260 men and 261 'vomen) to examine the impact of the alcohol flushing response on the relationship between alcohol consumption and serum y -GTP levels. The subjects were divided into three groups according to the amount .of daily alcohol consumption. (low, <20 g; moderate, 20-39 g;. and high, >40 g). Multiple adjustments were performed with linear regression models to examine the association between daily alcohol consumption and serum y-GTP levels, adjusting for potential con- founders including the flushing response. We found that the proportion of flushers was significantly lower in the high alcohol consumption group than in the low consumption group. The results of a multivariable analysis showed that,serum y -GTP levels were significantly higher in the moderate and high consumption groups than in the low consumption group after. adjusting for all potential confounders other than the flushing response. In addition, the association between serum y -GTP levels and alcohol consumption was unchanged after adjusting for the presence of the flushing response. In conclusion, serum y -GTP levels increased with increasing alcohol-consumption regardless of the flushing response. Screening for heavy drinkers using serum y-GTP levels was very important to prevent alcohol-related diseases or health problems in health examination.

BACKGROUND: The utility of casual serum triglyceride (TG) as a predictor of type 2 diabetes mellitus (DM) is unclear, especially during the most productive years. METHODS: Participants were 3271 workers (913 men and 2358 women, age 20-57) without DM at baseline. They underwent consecutive annual medical check-ups for 8 years. The association between newly diagnosed DM and casual serum TG level was determined by classifying the participants into 4 groups according to casual serum TG level at baseline: below 50 mg/dL (group A), 50-100 mg/dL (group B), 100-150 mg/dL (group C), and ≥150 mg/dL (group D). The effects of casual serum TG level in combination with sex, obesity, or serum glucose level on newly diagnosed DM were also evaluated. RESULTS: A total of 222 newly diagnosed type 2 DM cases with a mean age of 50 years old were observed during the follow-up period, i.e., 10/406 in group A, 66/1534 in group B, 58/712 in group C, and 88/619 in group D. Compared with group A, the odds ratio (ORs) for newly diagnosed DM (after adjusting for DM-associated factors) was found to increase with casual serum TG level: 1.38 (group B), 1.79 (group C), and 2.36 (group D). Moreover, the OR for newly diagnosed DM was higher in participants with high casual serum TG levels who were also male (OR 2.46), obese (OR 4.18), or had a high serum glucose level (OR 6.96) than in the reference group. CONCLUSIONS: Serum TG level ≥150 mg/dL when fasting or nonfasting is a significant predictor of type 2 diabetes in middle-aged Japanese workers.
RESUMO
BACKGROUND: An immediate ambulance call offers the greatest opportunity for acute stroke therapy. Effectively using ambulance services requires strengthening the association between knowledge of early stroke symptoms and intention to call an ambulance at stroke onset, and encouraging the public to use ambulance services. METHODS: The present study utilized data from the Acquisition of Stroke Knowledge (ASK) study, which administered multiple-choice, mail-in surveys regarding awareness of early stroke symptoms and response to a stroke attack before and after a 2-year stroke education campaign in two areas subject to intensive and moderate intervention, as well as in a control area, in Japan. In these three areas, 3833 individuals (1680, 1088 and 1065 participants in intensive intervention, moderate intervention, and control areas, respectively), aged 40 to 74 years, who responded appropriately to each survey were included in the present study. RESULTS: After the intervention, the number of correctly identified symptoms significantly associated with intention to call an ambulance (P < 0.05) increased (eg, from 4 to 5 correctly identified symptoms), without increasing choice of decoy symptoms in the intensive intervention area. Meanwhile, in other areas, rate of identification of not only correct symptoms but also decoy symptoms associated with intention to call an ambulance increased. Furthermore, the association between improvement in the knowledge of stroke symptoms and intention to call an ambulance was observed only in the intensive intervention area (P = 0.009). CONCLUSIONS: Our results indicate that intensive interventions are useful for strengthening the association between correct knowledge of early stroke symptoms and intention to call an ambulance, without strengthening the association between incorrect knowledge and intention to call an ambulance.

BACKGROUND: Several studies have reported that insulin resistance was a major risk factor for the onset of type 2 diabetes mellitus in individuals without diabetes or obesity. We aimed to clarify the association between insulin resistance and glycemic control in Japanese subjects without diabetes or obesity. METHODS: We conducted a community-based cross-sectional study including 1083 healthy subjects (323 men and 760 women) in an urban area. We performed multivariate regression analyses to estimate the association between the homeostasis model assessment of insulin resistance (HOMA-IR) values and markers of glycemic control, including glycated haemoglobin (HbA1c), 1,5-anhydroglucitol (1,5-AG), and fasting plasma glucose (FPG) levels, after adjustment for potential confounders. RESULTS: Compared with the lowest tertile of HOMA-IR values, the highest tertile was significantly associated with HbA1c and FPG levels after adjustment for potential confounders, both in men (HbA1c: ß = 1.83, P = 0.001; FPG: ß = 0.49, P < 0.001) and women (HbA1c: ß = 0.82, P = 0.008; FPG: ß = 0.39, P < 0.001). The highest tertile of HOMA-IR values was inversely associated with 1,5-AG levels compared with the lowest tertile (ß = -18.42, P = 0.009) only in men. CONCLUSIONS: HOMA-IR values were associated with markers of glycemic control in Japanese subjects without diabetes or obesity. Insulin resistance may influence glycemic control even in a lean, non-diabetic Asian population.

BACKGROUND: It is important that the general population be aware of the early symptoms, since it has been shown that early arrival to hospitals leads better prognosis of stroke patients. However, the general population is not well informed about the early symptoms of stroke. This study was conducted to clarify which stroke symptoms are less well known and which information sources are related to awareness of stroke symptoms. METHODS: A multiple-choice, mail-in survey involving 5,540 randomly selected residents, aged 40-74 years, of 3 cities in Japan was conducted. Their knowledge about stroke symptoms and their information sources were surveyed; information sources were classified as mass media (television/newspaper/radio) and personal communication sources (posters/leaflets/internet/health professionals/family and/or friends). 'Awareness' was defined as selecting all 5 of the correct stroke symptoms from among 10 listed symptoms with decoy choices. The estimated fraction of the possible impact due to each source on the whole population was also calculated by odds ratios (ORs) and the proportion of respondents who selected each source (Pe). The combined effects of mass media and personal communication sources on awareness were also assessed. RESULTS: Of the 5,540 residents, only 23% selected all 5 correct symptoms. Visual disturbance was the least known of the 5 symptoms (35%). All sources were positively related to awareness, with ORs (Pe) of: television, 1.58 (72.5%); newspaper, 1.79 (48.0%); radio, 1.74 (13.3%); posters, 1.73 (7.6%); leaflets, 1.50 (24.7%); Internet, 1.66 (5.6%); health professionals, 1.33 (34.8%), and family/friends, 1.21 (44.6%). The estimated fraction of the possible impact due to each source was higher for mass media (television, 0.31 and newspaper, 0.28) than personal communication sources (Internet, 0.04 and leaflets, 0.12). Mass media only and mass media/personal communication sources were significantly associated (ORs: 1.66, 2.75, respectively). CONCLUSIONS: As a single method of public education, television could be the most effective strategy. Moreover, the combined approach involving mass media and personal communication sources might have a synergistic effect. Less well-known symptoms, such as visual disturbances, should be noted in public education campaigns.

The preventive effect of aggressive blood pressure lowering on hematoma enlargement was investigated in patients with ultra-acute spontaneous intracerebral hemorrhage (ICH). Retrospective review of 248 patients (145 males, 103 females) with spontaneous ICH treated in our hospital between 2005 and 2008 identified patients with ultra-acute ICH who were directly taken to our institute by ambulance within 3 hours after onset. Patients who could not be assessed twice by computed tomography (CT) within 24 hours after arrival were excluded. Systolic blood pressure (SBP) was aggressively controlled in all patients using intravenous nicardipine to below 140 mmHg as soon as possible after diagnosis of ICH with CT. Hematoma enlargement was defined as increase in volume of more than 33% or more than 12.5 ml in the first 24 hours. Hematoma enlargement was observed in 11 of the 73 patients (15.0%). The time course of SBP change was not significantly different in patients with and without hematoma enlargement. The incidence of hematoma enlargement in patients with ultra-acute ICH in this study was 15.0%, which was lower than that in other series in which blood pressure was not reduced aggressively. This finding suggests that aggressive SBP lowering to below 140 mmHg has a preventive effect on hematoma enlargement in patients with ultra-acute ICH.

A 67-year-old woman presented with symptomatic infarction in the territory of the anterior inferior cerebellar artery manifesting as vertigo, vomiting, and right facial weakness. Basiparallel anatomic scanning (BPAS) magnetic resonance (MR) imaging combined with MR angiography demonstrated the occluded anterior inferior cerebellar artery. Common anatomic variations and limited detection of the smaller branches on MR angiography sometimes hinder evaluation of the occluded artery. BPAS-MR imaging may have a supplementary role to MR angiography in the diagnosis of cerebellar artery occlusions.

PURPOSE: Those who have brain metastases smaller than 30 mm in diameter and less than 5 in number can be treated less invasively with radiosurgery. This retrospective study evaluated the optimal brain magnetic resonance image (MRI) follow-up interval for non-small cell lung cancer (NSCLC) patients to detect radiosurgically manageable metachronous brain metastases (MBM). PATIENTS AND METHODS: The records of 551 patients with primary NSCLC, treated in our institute between 2002 and 2007, were reviewed. The initial brain MRI was performed within one month after diagnosis of NSCLC, and the follow-up brain MRI interval was at the discretion of physicians. The interval between the last MRI in which brain metastases were not found and the first MRI in which brain metastases were found was defined as the critical MRIs interval (CMI). The relationship between CMI and the maximum size or number of MBM was evaluated. RESULTS: Among reviewed patients, the initial MRI of 38 patients showed brain metastases and 29 patients were diagnosed as MBM. In these MBM patients, the median interval from diagnosis of NSCLC to diagnosis of brain metastases was 8.9 months. The median CMI was 4.7 (range: 1.6-18.9) months. All brain metastases smaller than 30 mm in maximum diameter were found when CMI was shorter than 6.0 months, although 5 or more brain metastases in number were detected even by shorter CMI than 3 months. CONCLUSION: Early detection of MBM by biannual MRI follow-up may provide NSCLC patients with more opportunities to have less invasive treatment.

INTRODUCTION: The aim of this study was to clarify the correlation and association of plasma IL-6 and PDMPs, both of which are associated with metabolic syndrome, in healthy individuals. MATERIALS AND METHODS: We conducted a cross-sectional study of 464 healthy Japanese volunteers (210 men and 254 women, median age 39 and 35years, respectively) who had no signs, symptoms or history of cardiovascular- or cerebrovascular disease and took no medications. We assayed their IL-6 levels with a conventional ELISA kit and their PDMP levels by ELISA and monoclonal antibodies against CD42b and CD42a (glycoprotein Ib and IX). RESULTS: By multivariate analysis, the plasma level of PDMP was correlated with diastolic blood pressure (p=0.015), platelet count (p<0.001), high sensitivity C-reactive protein, and the plasma level of IL-6 (p<0.001) in men (R(2)=0.454, p<0.001) and was correlated with platelet count (p<0.001) and the plasma level of IL-6 (p<0.001) in women (R(2)=0.159, p<0.001). Quartile range of plasma level of IL-6 was associated with plasma level of PDMP after adjustment for diastolic blood pressure, platelet count, and high sensitivity C-reactive protein in men (p<0.001) and associated with plasma level of PDMP after adjustment for platelet count in women (p<0.001). CONCLUSIONS: These results suggest the plasma IL-6 is correlated and associated with the plasma PDMPs, markers of activated platelets in healthy individuals.

AIM: The aim of this study was to clarify the relationship between platelet-derived microparticles (PDMPs) and the Framingham 10-yr coronary heart disease (CHD) risk score. METHODS: A cross-sectional study of healthy volunteers free of medication, and cardiovascular or cerebrovascular disease was conducted. The subjects were 190 Japanese men (median age 41). An ELISA kit and monoclonal antibodies against CD42b and CD42a (glycoprotein Ib and IX) were used. RESULTS: PDMPs are correlated with platelet count, high sensitivity C-reactive protein (hsCRP), and diastolic blood pressure by multivariate analysis (R(2)=0.316, p <0.001). Quartile range of PDMPs is significantly associated with the 10-yr CHD risk score after adjusting for age, platelet count, hsCRP, and hypertension (p=0.033) and for age, platelet count, hsCRP, and presence of metabolic syndrome (MS) (p=0.020). In individuals with a predicted 10-yr risk for CHD >or=8% (corresponding with the highest quartile), compared to those with a predicted 10-yr risk <8%, the odds ratio (OR), adjusted for age, platelet count, hsCRP, and hypertension, was 3.3 (1.2-8.9) and adjusted for age, platelet count, hsCRP, and MS, was 4.5 (1.6-11.8). The age-, platelet count-, hsCRP- and hypertension-adjusted OR for a 10-yr CHD risk score >or=8% was 0.8 (0.5-1.3) for hsCRP and 3.9 (1.6-9.4) for hypertension. The age-, platelet count-, hsCRP- and MS -adjusted OR for a 10-yr CHD risk score >or=8% was 0.7 (0.4-1.2) for hsCRP and 7.9 (2.6-24.5) for MS. CONCLUSION: Elevated PDMPs are associated with the 10-yr CHD risk score in healthy men.

OBJECTIVE: Cerebral microbleeds (CMB) on gradient-echo T2*-weighted magnetic resonance image (MRI) are frequently seen in patients with cerebral diseases. In this observational study we assessed whether CMB are a predictive factor for first-ever cerebrovascular events. PATIENTS AND METHODS: This study consisted of 698 subjects without a history of symptomatic cerebrovascular events, who received gradient-echo T2*-weighted MRI for 3 months between November 2003 and January 2004 in Kishiwada City Hospital, Osaka, Japan. These subjects were then observed as outpatients for over 3.5 years. RESULTS: The prevalence of CMB at baseline was 17.0% (119/698) in this population, and the follow-up rate was 51%. A total of 36 first-ever symptomatic cerebrovascular events were observed during the 3 and a half-year follow-up period. First-ever symptomatic cerebrovascular events occurred significantly more frequently in subjects with CMB (15 cases) than those without CMB (21 cases) (p=0.001). Even after adjusting for age, sex and hypertension, it was revealed that the presence of CMB was an independent predictor for the first-ever symptomatic cerebrovascular event by using the Cox proportional hazards model (hazard ratio, 2.87; 95% CI, 1.27-6.48; p=0.01). CONCLUSION: The presence of CMB is an independent predictor of first-ever symptomatic cerebrovascular diseases.

The validity of regular use of antiplatelet agents was retrospectively assessed in 106 patients with intracerebral hemorrhage (ICH) (supratentorial hemorrhage 92, lobar 22 and deep 70; and infratentorial hemorrhage 14) who underwent T(2)*-weighted gradient-echo magnetic resonance (MR) imaging between January 2005 and December 2006 in Kishiwada City Hospital. The prevalence of cerebral microbleeds was 54.7% (58/106), and the presence was significantly associated with higher age (odds ratio 3.09, p = 0.007), presence of white matter hyperintensity on T(2)-weighted MR imaging (odds ratio 2.36, p = 0.032), and previous ICH and/or cerebral infarction (odds ratio 4.77, p = 0.020). Previous ICH and/or cerebral infarction was independently associated with the presence of cerebral microbleeds after adjustment for age, white matter hyperintensity, and hypertension (odds ratio 4.07, p = 0.043). Regular use of antiplatelet agents was not associated with the presence of cerebral microbleeds, whether the patients had cerebrovascular diseases or not. Our findings suggest that antiplatelet medication can be justified for patients with cerebral microbleeds.
