Myocardial damage from heavy alcohol intake can cause the heart failure (HF) syndrome, but the relation of lighter alcohol intake to HF has rarely been studied. We examined the risk of HF hospitalization among 126,236 subjects who supplied data about alcohol during health examinations from 1978 to 1985. Among 2,594 subjects who were subsequently hospitalized for HF, record review established an association between coronary artery disease (CAD) and HF (CAD-HF) in 1,559 patients. Among the remaining 1,035 subjects who had HF (non-CAD-HF), we attempted determination of preponderant etiologic and contributory factors. Analyses used Cox models that were controlled for 7 covariates, with usual alcohol intake studied categorically compared with that in subjects who did not drink alcohol. Heavier drinkers (> or =3 drinks/day) but not light to moderate drinkers had increased risk of non-CAD-HF; e.g., relative risk for subjects who reported > or =6 drinks/day was 1.7 (95% confidence interval 1.1 to 2.6). This association of non-CAD-HF with heavy drinking was limited to subsets with cardiomyopathy or of unclear preponderant etiology. Alcohol drinking was inversely related to risk of CAD-HF (e.g., at 1 to 2 drinks/day, relative risk 0.6, 95% confidence interval 0.5 to 0.7), with consistency across subgroups of age, gender, ethnicity, education, smoking status, interval to diagnosis, and presence or absence of baseline heart disease or systemic hypertension. Moderate drinking was inversely related to non-CAD-HF only in subjects who had diabetes mellitus (n = 252). In conclusion, heavy, but not light, alcohol drinking is associated with increased risk of non-CAD-HF and that apparent protection by alcohol drinking against CAD-HF risk provides confirmation of a protective effect of alcohol against CAD.  相似文献

A locus for autosomal dominant anterior polar cataract on chromosome 17p   总被引:6,自引:3,他引:6  
Inherited cataract is a clinically and genetically heterogeneous disease. Here we report the identification of a new locus for an autosomal dominant anterior polar cataract on the short arm of chromosome 17. To map this new locus we performed genetic linkage analysis with microsatellite markers in a four-generation pedigree. After exclusion of seven candidate loci for cataract, we obtained significant positive LOD scores for markers D17S849 (Z = 4.01 / theta = 0.05) and D17S796 (Z = 4.17 / theta = 0.05). Multipoint analysis gave a maximum LOD score of 5.2 (theta max = 0.06) between these two markers. From haplotype analysis, the cataract locus lies in the 13 cM interval between markers D17S849 and D17S796. This study provides the first genetic mapping of an autosomal dominant anterior polar cataract.   相似文献

Using a case-control design, an association of schizophrenia with the dopamine D3 receptor gene (D3RG) locus was investigated. Initial analysis of pooled results from published studies revealed a significant excess of individuals homozygous for either allele among the patients. The association was next tested in two cohorts ascertained independently at Pittsburgh, Pennsylvania and at Houston, Texas. The Pittsburgh sample was comprised of patients with schizophrenia (DSM-III-R) (n = 130). The controls belonged to two groups: adults screened for the absence of substance abuse or major psychiatric illness (n = 128), and neonates (n = 160). Multivariate analysis suggested an association with allele 1 of the biallelic D3RG polymorphism in comparison with the adult, but not the neonatal, controls. The association was most marked among Caucasian patients with a family history of schizophrenia (odds ratio 13.69, confidence intervals 1.80, 104.30). Survival analysis suggested an earlier age of onset among male patients homozygous for allele 2. The Houston cohort included Caucasian patients with schizophrenia or schizoaffective disorder (DSM-III-R criteria, n = 50), and normal controls matched for gender (n = 51). In this group, no significant associations were noted among all the patients or among subgroups of patients based on family history or age of onset. Possible reasons for the discordant results are discussed. © 1996 Wiley-Liss, Inc.  相似文献

There is an increase in older-adult renal transplant recipients in United States. The objective of this study was to assess the association between physical function (PF) and patient survival in renal transplant recipients who are aged 65 years or older. Using United Network for Organ Sharing (UNOS) data from 2007 to 2016, renal transplant recipients aged 65 years or older were included. Multivariable Cox regression was used to assess associations between survival and functional status adjusted for age, sex, race, donor quality, diabetes, and dialysis vintage. The study identified 26,721 patients. Patient survival was significantly higher in recipients who needed no assistance and lowest in patients in need of total assistance (P < .0001). In deceased donor (DD) transplants, the relative risk for mortality was 2.06 (1.74-2.43) for total assistance and 1.17 (1.08-1.28) for moderate assistance compared to no assistance (P < .0001). In living donor (LD) transplants, the relative risk of mortality was 1.38 (0.78-2.42) for patients needing total assistance and 1.37 (1.14-1.65) for patients needing moderate assistance compared to patients who did not need assistance (0.003). PF is an independent predictor of post-transplant mortality. Assessment of older potential renal transplant recipients should include assessment and standardization of functional status to counsel about post-transplant survival.  相似文献

Solitary bronchioloalveolar carcinoma: CT criteria   总被引:14,自引:0,他引:14  
The computed tomographic (CT) scans of 30 patients with solitary bronchioloalveolar carcinoma were reviewed. Common features at CT included the peripheral or subpleural location of a pulmonary mass (25 cases), pseudocavitation (18 cases), heterogeneous attenuation (17 cases), irregular margins forming a star pattern (22 cases), and pleural tags (21 cases). Using these CT criteria, four independent observers attempted to identify cases of bronchioloalveolar carcinoma from a larger sample of lung cancers and benign lesions by categorizing a series of test cases into four probability categories. Although the bronchioloalveolar carcinomas were correctly ranked in the two highest probability categories 75% of the time (in 45 of 60 cases), there was considerable overlap with other lung lesions, particularly with adenocarcinoma and large cell undifferentiated carcinoma. However, even though the typical features of bronchioloalveolar carcinoma are not invariable or highly specific, they are characteristic enough to suggest the diagnosis.  相似文献

Focal liver masses: differential diagnosis with pulsed Doppler US   总被引:8,自引:0,他引:8  
Duplex Doppler ultrasound (US) was used in 68 consecutive patients with focal liver lesions, including 12 hepatocellular carcinomas, one cholangiocarcinoma, 37 metastases, 15 hemangiomas, one hemangioendothelioma, and two focal nodular hyperplasias. Of the hepatocellular carcinomas, six were diffusely hyperechoic, two were hypoechoic, two were single hyperechoic lesions, and two were multifocal and hyperechoic. All ten tumors with Doppler shifts of 5 kHz or above proved to be hepatocellular carcinomas. The other two hepatocellular carcinomas showed Doppler shifts of 3 kHz. In contrast, no hemangioma showed shifts above 0.7 kHz, and ten of the 15 gave no detectable signal. Of the metastases, 20 gave no signal and 17 had signals of up to 4 kHz. Three-kilohertz signals were also obtained from a cholangiocarcinoma, a hemangioendothelioma, and focal nodular hyperplasia. Correlation with angiographic findings suggested that the high-velocity Doppler signals were associated with large pressure gradients due to arteriovenous shunting. Duplex Doppler US can therefore aid in the differential diagnosis of diffuse and focal liver lesions.  相似文献

The depth of myometrial invasion by endometrial carcinoma was evaluated using real-time sonography (US) in 20 patients with histologically proved adenocarcinoma of the endometrium. In 14 of 20 (70%) cases, US-based estimation of the depth of myometrial invasion was within 10% of the actual measurement in the gross specimen. The US-based estimation of tumor invasion was low in seven patients, high in four patients, and agreed with pathologic findings (+/- 5%) in nine patients. In four patients with polypoid intraluminal extension of tumor, a deeply invasive tumor was suspected on US but was not found on pathologic examination. In 12 superficially invasive tumors, the continuity of the demarcating subendometrial halo was intact in nine and incomplete in three. In six patients with deeply invasive tumors, this zone was partially disrupted in four, totally disrupted in one, and intact in one. Errors of estimation of the depth of myometrial invasion on US most frequently occurred when a tumor had a significant intraluminal polypoid extension. Demonstration of a subendometrial halo usually indicated superficial invasion, whereas the absence of a halo was frequently associated with deep invasion.  相似文献

BACKGROUND: Our center sought to implement a simple chemoradiotherapy schedule for patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) with minimal toxicity to achieve rates of overall survival comparable to other schedules. METHODS: The chemoradiotherapy schedule consisted of daily radiation to 70 Gy over 7 weeks with concurrent cisplatin 20 mg/m(2) during days 1 to 4 of weeks 1 and 5. Acute and late toxicities were recorded according to the Radiation Therapy Oncology Group (RTOG) and common toxicity criteria (CTC) grading. The overall, disease-specific, and locoregional recurrence-free survival were calculated using the STATA statistics package. Possible factors influencing these endpoints were analyzed. RESULTS: Fifty-seven patients were treated, and 56 patients were evaluable for follow-up. Median follow-up of alive patients was 16.1 months. There was an 82% complete response rate to chemoradiotherapy. The 2-year Kaplan-Meier overall, disease-specific, and locoregional recurrence-free survival rates were 62%, 67%, and 63%. Acute grade 3 and 4 radiation toxicity was noted in 61% and 2%, respectively. Grade 3 or 4 hematologic toxicity was noted in 7% of patients. Factors influencing overall survival included: Karnofsky performance status, receiving more than 50% of planned chemotherapy, age, and initial hemoglobin level. CONCLUSION: This regimen is tolerable and achieves overall survival and locoregional control rates comparable to other chemoradiotherapy schedules.  相似文献
