Background
Current insights indicate that Web-based delivery may enhance the implementation of brief alcohol interventions. Previous research showed that electronically delivered brief alcohol interventions decreased alcohol use in college students and adult problem drinkers. To date, no study has investigated the effectiveness of Web-based brief alcohol interventions in reducing alcohol use in younger populations.Objective
The present study tested 2 main hypotheses, that is, whether an online multicomponent brief alcohol intervention was effective in reducing alcohol use among 15- to 20-year-old binge drinkers and whether inclusion of normative feedback would increase the effectiveness of this intervention. In additional analyses, we examined possible moderation effects of participant’s sex, which we had not a priori hypothesized.Method
A total of 575 online panel members (aged 15 to 20 years) who were screened as binge drinkers were randomly assigned to (1) a Web-based brief alcohol intervention without normative feedback, (2) a Web-based brief alcohol intervention with normative feedback, or (3) a control group (no intervention). Alcohol use and moderate drinking were assessed at baseline, 1 month, and 3 months after the intervention. Separate analyses were conducted for participants in the original sample (n = 575) and those who completed both posttests (n = 278). Missing values in the original sample were imputed by using the multiple imputation procedure of PASW Statistics 18.Results
Main effects of the intervention were found only in the multiple imputed dataset for the original sample suggesting that the intervention without normative feedback reduced weekly drinking in the total group both 1 and 3 months after the intervention (n =575, at the 1-month follow-up, beta = -.24, P = .05; at the 3-month follow-up, beta = -.25, P = .04). Furthermore, the intervention with normative feedback reduced weekly drinking only at 1 month after the intervention (n=575, beta = -.24, P = .008). There was also a marginally significant trend of the intervention without normative feedback on responsible drinking at the 3-month follow-up (n =575, beta = .40, P =.07) implying a small increase in moderate drinking at the 3-month follow-up. Additional analyses on both datasets testing our post hoc hypothesis about a possible differential intervention effect for males and females revealed that this was the case for the impact of the intervention without normative feedback on weekly drinking and moderate drinking at the 1-month follow-up (weekly drinking for n = 278, beta = -.80, P = .01, and for n = 575, beta = -.69, P = .009; moderate drinking for n = 278, odds ratio [OR] = 3.76, confidence interval [CI] 1.05 - 13.49, P = .04, and for n = 575, OR = 3.00, CI = 0.89 - 10.12, P = .08) and at the 3-month follow-up (weekly drinking for n = 278, beta = -.58, P = .05, and for n = 575, beta = -.75, P = .004; moderate drinking for n = 278, OR = 4.34, CI = 1.18 - 15.95, P = .04, and for n = 575, OR = 3.65, CI = 1.44 - 9.25, P = .006). Furthermore, both datasets showed an interaction effect between the intervention with normative feedback and participant’s sex on weekly alcohol use at the 1-month follow-up (for n = 278, beta = -.74, P =.02, and for n = 575, beta = -.64, P =.01) and for moderate drinking at the 3-month follow-up (for n = 278, OR = 3.10, CI = 0.81 - 11.85, P = .07, and for n = 575, OR = 3.00, CI = 1.23 - 7.27, P = .01). Post hoc probing indicated that males who received the intervention showed less weekly drinking and were more likely to drink moderately at 1 month and at 3 months following the intervention. For females, the interventions yielded no effects: the intervention without normative feedback even showed a small unfavorable effect at the 1-month follow-up.Conclusion
The present study demonstrated that exposure to a Web-based brief alcohol intervention generated a decrease in weekly drinking among 15- to 20-year-old binge drinkers but did not encourage moderate drinking in the total sample. Additional analyses revealed that intervention effects were most prominent in males resulting in less weekly alcohol use and higher levels of moderate drinking among 15- to 20-year-old males over a period of 1 to 3 months.Trial Registration

Clinicopathological concepts on acute and chronic liver disease have evolved rapidly during the last few years, with advances in general and specific treatment options and improved patient outcomes. The old paradigm of ‘irreversibility’ of cirrhosis had been challenged in major ways, and the validity of the usage of the term ‘cirrhosis’ has come into question. This paper addresses aetiology‐based clinicopathological concepts and features that may deserve attention because they may determine disease outcome and, specifically, patterns of regression and remodelling. A variety of therapeutic interventions may influence remaining disease features after elimination of damaging agents (virus, alcohol, etc.), and determine the final clinical outcome including the risk of hepatocellular carcinoma (HCC). New concepts create new responsibilities and opportunities for the pathologist to contribute to the understanding of liver pathology and communicate this with clinical colleagues and researchers. 相似文献

Background
Brief interventions have a modest but meaningful effect on promoting smoking cessation and reducing excessive alcohol consumption. Guidelines recommend offering such advice opportunistically and regularly but incentives vary between the two behaviours.Aim
To use representative data from the perspective of patients to compare the prevalence and characteristics of people who smoke or drink excessively and who receive a brief intervention.Design and setting
Data was from a representative sample of 15 252 adults from household surveys in England.Method
Recall of brief interventions on smoking and alcohol use, sociodemographic information, and smoking and alcohol consumption patterns were assessed among smokers and those who drink excessively (AUDIT score of ≥8), who visited their GP surgery in the previous year.Results
Of 1775 smokers, 50.4% recalled receiving brief advice on smoking in the previous year. Smokers receiving advice compared with those who did not were more likely to be older (odds ratio [OR] 17-year increments 1.19, 95% confidence interval [CI] =1.06 to 1.34), female (OR 1.35, 95% CI =1.10 to 1.65), have a disability (OR 1.44, 95% CI = 1.11 to 1.88), have made more quit attempts in the previous year (compared with no attempts: one attempt, OR 1.65, 95% CI = 1.32 to 2.08; ≥2 attempts, OR 2.02, 95% CI =1.49 to 2.74), and have greater nicotine dependence (OR 1.17, 95% CI =1.05 to 1.31) but were less likely to have no post-16 qualifications (OR 0.81, 95% CI = 0.66 to 1.00). Of 1110 people drinking excessively, 6.5% recalled receiving advice in their GP surgery on their alcohol consumption in the previous year. Those receiving advice compared with those who did not had higher AUDIT scores (OR 1.17, 95% CI =1.12 to 1.23) and were less likely to be female (OR 0.44, 95% CI = 0.23 to 0.87).Conclusion
Whereas approximately half of smokers in England visiting their GP in the past year report having received advice on cessation, <10% of those who drink excessively report having received advice on their alcohol consumption. 相似文献5.

Background
Internet-based interventions for heavy drinkers show promising results, but existing research is characterized by few studies in nonstudent adult populations and few comparisons with appropriate control groups.Objective
To test whether a fully automated Internet-based brief personalized feedback intervention and a fully automated Internet-based personalized brief advice intervention in a non-treatment-seeking population of heavy drinkers would result in a reduced alcohol intake.Methods
We conducted a 3-arm parallel randomized controlled trial in a general population-based sample of heavy drinkers. The 54,157 participants (median age of 58 years) were screened for heavy drinking. Of the 3418 participants who had a weekly alcohol consumption above 14 drinks for women and 21 drinks for men, 1380 (619 women) consented to take part in the trial and were randomly assigned to an Internet-based brief personalized feedback intervention group (normative feedback, n = 476), an Internet-based personalized brief advice intervention group (n = 450), or a nonintervention control group (n = 454). Follow-up after 6 and 12 months included 871 and 1064 participants, respectively, of all groups combined. The outcome measure was self-reported weekly alcohol consumption. We analyzed the data according to the intention-to-treat principle. To examine changes over time and to account for the multiple time measurements, we used a multilevel linear mixed model. To take attrition into account, we used multiple imputation to address missing data.Results
The intervention effect of the Internet-based brief personalized feedback intervention, determined as the mean additional difference in changes in alcohol consumption in the Internet-based brief personalized feedback intervention compared with the control group, was –1.8 drinks/week after 6 months and –1.4 drinks/week after 12 months; these effects were nonsignificant (95% confidence interval –4.0 to 0.3 at 6 months, –3.4 to 0.6 at 12 months). The intervention effect of the Internet-based personalized brief advice intervention was –0.5 drinks/week after 6 months and –1.2 drinks/week after 12 months; these effects were nonsignificant (95% confidence interval –2.7 to 1.6 at 6 months, –3.3 to 0.9 at 12 months).Conclusions
In this randomized controlled trial we found no evidence that an Internet-based brief personalized feedback intervention was effective in reducing drinking in an adult population of heavy drinkers.Trial registration

AIMS: To determine the expression of a protein termed augmenter of liver regeneration (ALR), recently found to have a specific and beneficial effect on the process of liver regeneration in normal and diseased human liver. METHODS AND RESULTS: ALR expression in normal and cirrhotic human livers with various underlying diseases as well as in tissue samples of hepatocellular carcinoma (HCC) and cholangiocellular carcinoma (CCC) was analysed by immunohistochemistry and quantitative reverse transciptase-polymerase chain reaction (RT-PCR). Expression analysis of ALR in total liver protein extracts by Western blotting showed mainly dimeric ALR protein. Immunohistochemically, cytosolic and perinuclear immunosignals were found in hepatocytes and cholangiocytes in normal, cirrhotic or cancerous liver tissue and only weak signals in some endothelial cells in normal livers. Quantitative mRNA analysis revealed significantly increased ALR expression in cirrhosis compared with normal liver tissue. In HCC and CCC ALR mRNA expression was also significantly enhanced compared with normal liver tissue, but expression levels did not differ from the matching non-neoplastic tissue in the same patient. CONCLUSIONS: The findings suggest an important role for ALR in hepatocellular regeneration in liver cirrhosis as well as in hepatocarcinogenesis and therefore its potential value in the clinical diagnosis of hepatic cirrhosis and cancer. 相似文献

Whereas reminiscence‐based interventions that focus on reducing depression and pessimism have been shown to be effective, most studies have employed longer term treatments. There has also been a tendency for reminiscence‐based studies to focus on the benefits of reminiscence for older adults, with few studies involving younger adults. This study examined the efficacy of a one‐session reminiscence‐based intervention for reducing depressed affect and pessimism in younger adults. A total of 26 non‐clinical participants were administered a one‐to‐one guided interview in which they were encouraged to recall past problem‐solving successes, and the lessons learnt from these successes. Measures of affect, pessimism, and mastery were administered pre‐ and post‐interview. Levels of depressed affect, mastery, and pessimism significantly improved following the interview, compared with baseline levels. Changes in mastery were associated with changes in pessimism, but not with changes in depressed affect. This study suggests that a one‐session reminiscence‐based intervention may significantly contribute to the improvements in depressed affect, pessimism, and mastery in a younger cohort. It also suggests that the improvement in pessimism may be accounted for by improvement in self‐mastery. 相似文献

Background
Computer-delivered psychological treatments have great potential, particularly for individuals who cannot access traditional approaches. Little is known about the acceptability of computer-delivered treatment, especially among those with comorbid mental health and substance use problems.Objective
The objective of our study was to assess the acceptability of a clinician-assisted computer-based (CAC) psychological treatment (delivered on DVD in a clinic-setting) for comorbid depression and alcohol or cannabis use problems relative to a therapist-delivered equivalent and a brief intervention control.Methods
We compared treatment acceptability, in terms of treatment dropout/participation and therapeutic alliance, of therapist-delivered versus CAC psychological treatment. We randomly assigned 97 participants with current depression and problematic alcohol/cannabis use to three conditions: brief intervention (BI, one individual session delivered face to face), therapist-delivered (one initial face-to-face session plus 9 individual sessions delivered by a therapist), and CAC interventions (one initial face-to-face session plus 9 individual CAC sessions). Randomization occurred following baseline and provision of the initial session, and therapeutic alliance ratings were obtained from participants following completion of the initial session, and at sessions 5 and 10 among the therapist-delivered and CAC conditions.Results
Treatment retention and attendance rates were equal between therapist-delivered and CAC conditions, with 51% (34/67) completing all 10 treatment sessions. No significant differences existed between participants in therapist-delivered and CAC conditions at any point in therapy on the majority of therapeutic alliance subscales. However, relative to therapist-delivered treatment, the subscale of Client Initiative was rated significantly higher among participants allocated to the BI (F2,54 = 4.86, P = .01) and CAC participants after session 5 (F1,29 = 9.24, P = .005), and this domain was related to better alcohol outcomes. Linear regression modeled therapeutic alliance over all sessions, with treatment allocation, retention, other demographic factors, and baseline symptoms exhibiting no predictive value.Conclusions
Participants in a trial of CAC versus therapist-delivered treatment were equally able to engage, bond, and commit to treatment, despite comorbidity typically being associated with increased treatment dropout, problematic engagement, and complexities in treatment planning. The extent to which a client feels that they are directing therapy (Client initiative) may be an important component of change in BI and CAC intervention, especially for hazardous alcohol use.Trial Registration

Alcohol-related liver disease (ALD) consists of a wide spectrum of clinical manifestations and pathological features, ranging from asymptomatic patients to decompensated cirrhosis and hepatocellular carcinoma. Patients with heavy alcohol intake and advanced fibrosis often develop a subacute form of liver failure called alcohol-induced hepatitis (AH). Globally, most patients with ALD are identified at late stages of the disease, limiting therapeutic interventions. Thus, there is a need for early detection of ALD patients, which is lacking in most countries. The identification of alcohol misuse is hampered by the existence of alcohol underreporting by many patients. There are useful biomarkers that can detect recent alcohol use. Moreover, there are several non-invasive techniques to assess the presence of advanced fibrosis among patients with alcohol misuse, which could identify patients at high risk of liver related events or early death. In this review, we discuss differences between early stages of ALD and AH as the cornerstone of advanced forms. A global overview of epidemiological, anthropometric, clinical, analytical, histological, and molecular differences is summarized in this article. We propose that campaigns aimed at identifying patients with subclinical forms can prevent the development of life-threatening forms. 相似文献

Liver fibrosis staging is a key element driving the prognosis of patients with chronic liver disease. Currently, biopsy is the only technique capable of diagnosing liver fibrosis in patients with alcohol-related liver disease (ArLD) and nonalcoholic fatty liver disease (NAFLD) unequivocally. Noninvasive (e.g. plasma-based) biomarker assays are attractive tools to diagnose and stage disease, yet must prove that they are reliable and sensitive to be used clinically. Here, we demonstrate proton nuclear magnetic resonance as a method to rapidly quantify the endogenous concentration of ammonium ions from human plasma extracts and show their ability to report upon early and advanced stages of ArLD and NAFLD. We show that, irrespective of the disease etiology, ammonium concentration is a more robust and informative marker of fibrosis stage than current clinically assessed blood hepatic biomarkers. Subject to validation in larger cohorts, the study indicates that the method can provide accurate and rapid staging of ArLD and NAFLD without the need for an invasive biopsy. 相似文献

This study was carried out to determine whether stainable copper accumulates in the hepatocytes of patients with alcoholic liver disease. Liver sections from 44 cases of alcoholic cirrhosis and 32 cases of non-cirrhotic alcoholic liver disease were stained by the rubeanic acid, rhodanine and orcein methods. Intrahepatocytic copper granules were found in 13 cases of cirrhosis (30%), but in none of the non-cirrhotic livers. The abundance of granules did not appear to be related either to the activity of the cirrhotic process or to the presence of cholestasis. It may well be that alcoholic cirrhosis is the most common disease associated with excess of intrahepatocytic copper. 相似文献

Patterns of histological change in liver disease: my approach to 'medical' liver biopsy reporting 总被引:1,自引:0,他引:1
Bateman AC 《Histopathology》2007,51(5):585-596
The aim of this review was to emphasize the benefit of a methodical approach to 'medical' liver biopsy reporting and to illustrate that recognition of patterns of disease can greatly aid correct interpretation of these often-complex specimens. This applies both to assessment of the liver architecture and to evaluation of the likely disease aetiology. Therefore, a great deal of information can be obtained by examining biopsy material at low- and medium-power magnification, prior to confirming detailed features with high-power examination. A range of recommended special histochemical stains that personal experience has shown to be valuable is included. Emphasis is also placed on the absolutely key requirement for appropriate knowledge of the clinical situation within which the biopsy specimen was taken. 相似文献

Primary splenic lymphoma is rare as non-Hodgkin lymphomas. Splenic infiltration of lymphoma cells may cause splenomegaly in many cases. However, splenomegaly is caused not only by tumor involvement but also by non-tumorous disorders. One of the most prevalent non-neoplastic causes is portal hypertension mostly due to liver cirrhosis. On the other hand, liver cirrhosis may underlie various extrahepatic manifestations including development of B-cell non-Hodgkin lymphomas. Here, we report a case of primary follicular lymphoma of the spleen in a patient with liver cirrhosis related to hepatitis C and alcohol. The lymphoma was incidentally found in an enlarged spleen resected palliatively to alleviate symptomatic pancytopenia of the patient. The main characteristic of our case is an incidental finding of a rare situation brought by careful pathological examination. Our case illustrates the importance to recognize a possibility of co-occurrence of chronic liver disease and extrahepatic lymphoma. 相似文献

PurposeThe aldehyde dehydrogenase 2 (ALDH2) gene has been implicated in the development of alcoholic liver cirrhosis (ALC) in East Asians. However, the results are inconsistent. In this study, a meta-analysis was performed to assess the associations between the ALDH2 polymorphism and the risk of ALC.ResultsA total of twelve case-control studies included 1003 cases and 2011 controls were included. Overall, the ALDH2 polymorphism was associated with a decreased risk of ALC (*1/*2 vs. *1/*1: OR=0.78, 95% CI: 0.61–0.99). However, in stratification analysis by country, we failed to detect any association among Chinese, Korean or Japanese populations.ConclusionThe pooled evidence suggests that ALDH2 polymorphism may be an important protective factor for ALC in East Asians. 相似文献

Background
Liver disease is a major cause of morbidity and mortality worldwide. Large numbers of liver function tests (LFTs) are performed in primary care, with abnormal liver biochemistry a common finding. Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver injury. Metabolic syndrome, common in people from South Asia, is an important risk factor for NAFLD.Aim
It is hypothesised that a large gap exists between numbers of patients with abnormal LFTs and those with recorded liver diagnoses, and that NAFLD is more common among adults of South Asian ethnic groups.Design and setting
A cross-sectional study of 690 683 adults in coterminous general practices in a region with high ethnic diversity.Method
Data were extracted on LFTs, liver disease, and process of care measures from computerised primary care medical records.Results
LFTs were performed on 218 032 patients, of whom 31 627 had elevated serum transaminases. The prevalence of abnormal LFTs was highest among individuals of Bangladeshi ethnicity. Of the patients with abnormal LFTs, 88.4% did not have a coded liver diagnosis. NAFLD was the most frequently recorded liver disease and was most common among Bangladeshi patients. In a multivariate analysis, independent risk factors for NAFLD included Bangladeshi ethnicity, diabetes, raised BMI, hypertension, and hypercholesterolaemia.Conclusion
Abnormal LFTs are common in the population, but are underinvestigated and often remain undiagnosed. Bangladeshi ethnicity is an important independent risk factor for NAFLD. 相似文献20.
Nitric oxide (NO), a recently discovered free radical, is overproduced in liver cirrhosis. Hepatitis C virus (HCV) might increase NO levels via increased inducible NO synthase (iNOS). This work was carried out to study the effect of HCV-induced liver cirrhosis on NO levels among Egyptian patients. The study included 46 patients with liver cirrhosis, and 30 healthy individuals of matched age and sex. NO levels determined as the stable endproduct nitrate, showed a statistically significant increase among patients compared to the control group (P < 0.001). Furthermore, NO levels increased proportionally with the severity of liver cirrhosis as assessed by Child's classification (P < 0.05). Moreover, schistosomial infection enhanced NO levels in cirrhotic patients with HCV infection compared to non-bilharzial patients (P < 0.001). Polymerase chain reaction (PCR) and branched DNA assays were used for detection of HCV RNA positivity, and measurement of the virus load, respectively. Both showed a positive correlation with the NO levels (P < 0.001). At a nitrate cutoff value of 70 micromol/L, the sensitivity and specificity were 83.0% and 73.0%, respectively. Chi square analysis showed a significant correlation between ALT levels and both HCV RNA positivity by polymerase chain reaction (PCR) (P < 0.02), and virus load (P<0.05). Interestingly enough, there was a significant positive correlation between HCV RNA and schistosomal antibody titer as measured by hemaglutination inhibition assay (HAI) (P < 0.05). The data presented in this report indicated an association between NO levels and the development and progression of liver cirrhosis. Furthermore, the findings obtained from this study demonstrated that schistomiasis is an important risk factor involved in enhancement of NO levels and virus replication. The latter may aggravate liver cell injury and hence the development of cirrhosis. 相似文献
