Objective: The objective of this study was to determine whether a new diagnosis of asthma is associated with a later diagnosis of herpes zoster (HZ) in a nationwide, retrospective, non-age limited, population-based cohort. Methods: We used data from the National Health Insurance Research Database in Taiwan. The asthma group consisted of all 40 069 patients in the database with newly diagnosed asthma and using asthma medications from 2000 through 2005. The nonasthma group comprised 40 069 age- and sex-matched patients without any asthma diagnosis. Cox proportional hazards regression analysis was applied to calculate the hazard ratio of HZ in the patients with asthma relative to those without asthma. Results: During a mean follow-up period of 8.77 years, the risk of HZ was 1.48-fold higher in the asthma group compared with that in the nonasthma group after adjustment for sex, age, comorbidities, inhaled and systemic corticosteroid use, and annual outpatient department visits to dermatologists. Additional stratified analyses revealed that the risk of HZ was significantly higher in patients of both sexes and those aged older than 21 years. Conclusions: Newly diagnosed adult patients with asthma have a significantly higher risk of developing HZ than do those without asthma. 相似文献

An association between impaired lower respiratory function and cardiovascular risk factors, such as hypertension, is often reported but it is unknown whether there is a relationship between upper airway disorders and cardiovascular risk factors, despite evidence that upper and lower respiratory tract disorders are closely linked. Our objective was to assess whether rhinitis is associated with arterial blood pressure and hypertension. In a population-based study of 330 adults aged 28-56 years, as part of the European Community Respiratory Health Survey, rhinitis was assessed by means of a questionnaire, and cardiovascular data were obtained using a questionnaire and by measuring blood pressure. Systolic blood pressure (SBP) was higher in men with rhinitis than in men without rhinitis (130.6 +/- 12.7 mm Hg versus 123.5 +/- 13.9 mm Hg; p = 0.002), and it was still the case after adjustment for cardiovascular and respiratory confounding factors. Hypertension was more frequent in men with rhinitis than in men without rhinitis, even after multivariate adjustment (odds ratio = 2.6, 95% confidence interval = [1.14-5.91]). The observation of SBP levels according to whether men have no rhinitis, seasonal rhinitis, or perennial rhinitis was compatible with a dose-response relationship (p for trend = 0.02). In conclusion, rhinitis is strongly associated with SBP and hypertension in men. Blood pressure should be regularly checked in men with rhinitis. 相似文献

A Western lifestyle has been implicated in the pathogenesis of prostate cancer. However, no clear association between obesity and prostate cancer has been shown. Leptin may stimulate prostate growth and angiogenesis, and receptors for leptin are present in the prostate. Leptin may, thus, be associated with increased risk of prostate cancer. One hundred forty-nine men with prostate cancer were identified (together with 298 matched referents) who, before diagnosis, had participated in population-based health surveys in Northern Sweden. Blood pressure, body mass index, and use of tobacco were recorded. Leptin, insulin, insulin-like growth factor I (IGF-I), IGF-I-binding proteins 1-3, testosterone, and sex hormone-binding globulin were analyzed in stored samples. Their influences on prostate cancer were estimated by conditional logistic regression analysis. Prostate cancer specimens were investigated for immunoreactivity for the leptin receptor. Relative risk (95% confidence intervals) estimates of prostate cancer over the quintiles of leptin were 1.0, 2.1 (1.1-4.1), 2.6 (1.4-4.8), 1.4 (0.7-2.7), and 1.6 (0.8-3.2). Adjustments for metabolic variables, testosterone, and IGF-I and its binding proteins did not attenuate this increased risk. Immunoreactivity for the leptin receptor was detected in normal, high-grade prostatic intraepithelial neoplasia lesions and malignant prostatic epithelium. Moderately elevated plasma leptin concentrations are associated with later development of prostate cancer. This may be due to direct effects of leptin on prostatic intraepithelial neoplasia lesions, or to indirect actions through other mechanisms. A critical fat mass related to an interior milieu favorable for prostate cancer development seems to exist, because intermediate but not high leptin levels are related to prostate cancer risk. 相似文献

This study examined the risk of recurrent venous thromboembolism (VTE) in patients with elevated albuminuria. In 1997-1998, inhabitants of Groningen, the Netherlands, aged 28-75 years (n=85,421), were invited to participate in the PREVEND (Prevention of REnal and Vascular ENd stage Disease) Study, an observational, population-based cohort study. Albuminuria was measured and VTE occurrence was monitored in responding subjects (n=40,856). Patients with first VTE between study entry and January 2009, identified through databases of the national registry of hospital discharge diagnoses, death certificates, regional anticoagulation clinic and medical records, were used for analysis. Of 351 subjects with first VTE, 37 subjects developed a recurrence during a median follow-up period of 3.3 (interquartile range, 1.1-6.4) years. The annual incidence of recurrence in subjects with elevated albuminuria (≥ 20 mg/l) was 5.00% [95% confidence interval (CI); 2.16-9.85], compared to 2.38% (95%CI; 1.59-3.41) in subjects with normal albuminuria (<20 mg/l). Hazard ratio for recurrence was 1.95 (95%CI; 0.89-4.30) after adjustment for age and sex. This hazard ratio was 3.35 (95%CI; 1.18-9.47) in patients with first unprovoked, and 1.12 (95%CI; 0.25-5.01) in those with a first provoked event. This study showed that subjects with elevated albuminuria who experience an unprovoked VTE are at an increased risk of recurrence, independent of age and sex. 相似文献

BACKGROUND: Gastrointestinal symptoms are reportedly common in diabetes, but a causal link is controversial and adequate population control data are lacking. OBJECTIVE: To determine whether gastrointestinal symptoms are more frequent in persons with diabetes, particularly in those with poor glycemic control. METHODS: Fifteen thousand adults were mailed a questionnaire (response rate, 60.0%) containing validated questions on the frequency of troublesome gastrointestinal symptoms within the past 3 months, diabetic status, and self-reported glycemic control. The prevalence of 16 symptoms and 5 symptom complexes, reported to occur often or very often, was compared using logistic regression analysis, adjusting for age and sex. RESULTS: Overall, 8657 eligible subjects responded; 423 (4.9%) reported having diabetes. Most (94.8%) had type 2 diabetes mellitus. Adjusting for age and sex, all 16 symptoms and the 5 symptom complexes were significantly more frequent in subjects with diabetes compared with controls. An increased prevalence rate of symptoms was significantly associated with poorer levels of glycemic control but not with duration of diabetes or type of diabetic treatment. CONCLUSIONS: Diabetes mellitus is associated with an increased prevalence of upper and lower gastrointestinal symptoms. This effect may be linked to poor glycemic control but not to duration of diabetes or type of treatment. 相似文献

OBJECTIVES: The "hygiene hypothesis" postulates that individuals raised in a sanitary environment are more likely to develop inflammatory bowel disease (IBD). Several studies previously demonstrated contradictory results in this regard. We performed for the first time a population-based study on the association of surrogate markers of childhood hygiene with the risk for IBD. METHODS: A cross-sectional population-based study was undertaken. Information on number of siblings, birth order, and living in an urban versus rural environment was obtained for 399,251 Jewish adolescents at the age of 17 yr from 1998 to 2004. The study population included only subjects born in Israel. In order to control for genetic confounding, subjects were also divided according to their ethnic group as being Ashkenazi, Sephardic, or Israeli in origin. RESULTS: In total, 768 cases of inflammatory bowel disease (IBD) were diagnosed (0.19%), with 53.8% of the cases being of Ashkenazi origin. On multivariate analysis, variables significantly associated with IBD were male gender (odds ratio [OR] 1.44, 95% confidence interval [CI] 1.24–1.67), Ashkenazi origin (OR 1.91, 95% CI 1.63–2.22), living in an urban environment (OR 1.38, 95% CI 1.02–1.78), small number of siblings in the family (for 1 sibling vs 5 or more, OR 2.63, 95% CI 1.49–4.62), and higher birth order (for birth order of 5 or higher vs 1, OR 2.35, 95% CI 1.47–3.77), showing for both variables an almost strictly highly significant monotonic association ( P value for trend <0.001). CONCLUSIONS: Surrogate markers of childhood hygiene are associated with the risk for IBD, thus reinforcing the "hygiene hypothesis." 相似文献

The prevalence of chronic gastrointestinal symptoms and the irritable bowel syndrome (IBS) in the elderly, and their impact on health, is largely unknown. The prevalence of symptoms compatible with IBS was estimated in a representative sample of elderly community residents, and the impact of these symptoms was determined on presentation for health care. An age- and sex-stratified random sample of noninstitutionalized Olmsted County, Minnesota, residents aged 65-93 years were mailed a valid questionnaire; 77% responded (n = 328). The age- and sex-adjusted prevalence (per 100 persons) of frequent abdominal pain was 24.3 [95% confidence interval (CI), 19.3-29.2]. Chronic constipation and chronic diarrhea had prevalences of 24.1 (95% CI, 19.1-29.0) and 14.2 (95% CI, 10.1-18.2), respectively. Fecal incontinence more than once a week was reported in 3.7 per 100 (95% CI, 1.6-5.9). The prevalence of symptoms compatible with IBS (greater than or equal to 3 Manning criteria with frequent abdominal pain) was 10.9 per 100 (95% CI, 7.2-14.6). Among the subjects sampled who had abdominal pain, chronic constipation, and/or chronic diarrhea (n = 152), only 23% had seen a physician for pain or disturbed defecation in the prior year, and this behavior was poorly explained by the symptoms. It is concluded that complaints consistent with functional gastrointestinal disorders are common in the elderly, but symptoms are a poor predictor of presentation for medical care. 相似文献

Background: The etiology behind functional gastrointestinal symptoms is not clear. Only a few studies have examined how lifestyle factors affect these symptoms, especially in middle-aged or elder subjects. The aim of the present study was to describe the prevalence of functional gastrointestinal symptoms in a Swedish population-based cohort of middle-aged to elder subjects, and to examine associations between symptoms and smoking and alcohol use. Methods and materials: This study was conducted on a web-based baseline questionnaire from a part of the EpiHealth study. The cohort included 16,840 subjects between 45 and 75 years of age. Subjects with organic gastrointestinal diseases were excluded. Gastrointestinal symptoms were defined as functional abdominal pain, functional bloating, functional constipation, and functional diarrhea. Parameters regarding age, gender, educational level, occupation, civil status, physical activity, and body mass index (BMI) were described, and association between smoking and alcohol habits were calculated, adjusted for parameters with >5 percentage difference between cases and controls. Results: An association was found between former and current smoking and functional abdominal pain (OR: 1.15, 95% CI: 1.03–1.28 vs. OR: 1.30, 95% CI: 1.08–1.57). Former smoking was associated with functional bloating (OR: 1.18, 95% CI: 1.04–1.33) and functional constipation (OR: 1.28, 95% CI: 1.06–1.56). There was a trend of decreased functional abdominal pain, functional constipation, and functional diarrhea in subjects with a moderate alcohol intake. Conclusion: Smoking is associated with functional abdominal pain, functional bloating, and functional constipation. A moderate alcohol intake tends to be associated with decreased risk of functional gastrointestinal symptoms. 相似文献

OBJECTIVES: To determine whether arterial stiffness is associated with depression in the elderly. DESIGN: Population-based cross-sectional study. SETTING: In Ommoord, a suburb of Rotterdam, the Netherlands. PARTICIPANTS: Three thousand seven hundred four subjects of the Rotterdam Study aged 60 and older. MEASUREMENTS: Arterial stiffness was assessed using the distensibility of the carotid artery and the carotid-femoral pulse wave velocity. All participants were screened for depressive symptoms with the Center for Epidemiologic Studies-Depression scale. Those with depressive symptoms had a psychiatric evaluation to establish a diagnosis of depressive disorders according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. RESULTS: Participants with increased arterial stiffness were more likely to have depressive symptoms. Odds ratios (ORs) for depressive symptoms were 1.24 (95% confidence interval (CI) = 1.01-1.52) per standard deviation decrease in carotid distensibility and 1.17 (95% CI = 1.00-1.38) per standard deviation increase in aortic pulse wave velocity. The association was stronger for depressive disorders meeting DSM-IV criteria (OR = 1.44, 95% CI = 1.03-2.03; OR = 1.48, 95% CI = 1.16-1.90, respectively). Control for atherosclerosis, as measured by the ankle-to-brachial index or presence of plaques in the carotid artery, did not change the associations. CONCLUSION: This study shows an association between arterial stiffness and depression in the elderly. The findings are compatible with the vascular depression hypothesis. These data suggest that arterial stiffness may partly cause the proposed relationship between vascular factors and depression. 相似文献

Studies have confirmed correlation between metabolic syndrome (MetS) and chronic obstructive pulmonary disease (COPD). However, to date, no studies have analyzed correlation between exacerbations of COPD (ECOPD) and MetS. The aim of this preliminary study was to examine if presence of MetS increases the frequency and duration of ECOPD. Patients with COPD were prospectively enrolled and followed between March 2008 and September 2009. Medical records, pulmonary function tests, chest X-rays; laboratory test results were gathered to establish the presence of COPD and MetS. Patients were divided in two groups; with and without MetS. The ECOPD was defined as worsening of symptoms requiring increased use of rescue medications and/or need for either systemic steroids or antibiotics or that led to emergency room visit or hospitalizations during 12 months follow-up. A total of 106 patients were recruited, 29 with MetS and 77 without. The mean exacerbation of COPD frequency was 2.4 ± 0.8 in MetS group versus 0.68 ± 0.6 in the control group during the follow-up period (P < 0.001). Mean duration of each exacerbation was 7.5 ± 1.5 days in patients with MetS versus 5 ± 2.4 days in patients without. Serum C-reactive protein (r = 0.31, P = 0.001), fasting blood glucose (r = 0.55, P < 0.001), and triglycerides (r = 0.251, P = 0.01) were positively and significantly correlated with exacerbation frequency. This study demonstrates an association between ECOPD and its duration with the MetS. The systemic inflammation induced by common cytokines may explain the linkage between the two conditions. 相似文献

OBJECTIVES: This study evaluated whether obesity in humans was associated with an increase in circulating hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) levels. BACKGROUND: Obesity acts as a cardiovascular risk factor by mechanisms that are not fully understood. Adipose tissue is able to secrete multiple cytokines and growth factors ex vivo. We hypothesized that the increased presence of adipose tissue in obese subjects results in systemic elevations of the mitogenic factors HGF and VEGF. METHODS: Blood samples were obtained from lean (n = 21) and obese (n = 44) volunteers. Serum HGF and VEGF levels were assessed by enzyme-linked immunoadsorbent assay. Insulin and fasting glucose levels were measured to evaluate insulin sensitivity. Conditioned medium of adipose cells was assayed for HGF secretion. RESULTS: Serum HGF levels in obese subjects were more than three-fold higher than those of lean subjects (2,462 +/- 184 pg/ml vs. 765 +/- 48 pg/ml, p < 0.0001). The VEGF levels were not significantly elevated in obese subjects (135 +/- 31 pg/ml vs. 128 +/- 37 pg/ml). The HGF concentrations, but not VEGF concentrations, were significantly correlated with body mass index (BMI) (p < 0.0001, r = 0.74). The observed increases in HGF concentrations of obese subjects were not secondary to insulin resistance or hypertension. Freshly isolated human adipose cells secreted HGF. CONCLUSIONS: Our results indicate that obesity is associated with a marked increase in circulating HGF levels, which correlate linearly with BMI. Because vascular growth factors have been associated with the pathogenesis of atherosclerosis, the possible role of such humoral factors as a link between obesity and cardiovascular disease is very intriguing. 相似文献
