[PMID: 37289263 DOI: 10.1007/s00520-023-07856-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 05/31/2023] [Indexed: 06/09/2023]
Abstract
INTRODUCTION New agents are introduced each day to be used in the prevention and treatment of mucositis in cancer treatment. One of those agents is the Ankaferd hemostat. Ankaferd hemostat has pleiotropic effects and anti-infective characteristics in tissue healing. METHODS The study was designed as a randomized controlled experimental study. The sample of the study comprised a total of 66 patients (33 patients in the Ankaferd hemostat group and 33 patients in the sodium bicarbonate group) with colorectal cancer who received FOLFOX combination chemotherapy treatment in the first cycle of chemotherapy to prevent mucositis. Participants who met the criteria were randomly assigned to the groups. Before the patient received chemotherapy, ECOG performance score and Oral Mucositis Grading Scale were applied on the 7th day and 15th day. The Ankaferd hemostat group brushed teeth at least twice a day for 2 min and gargled with Ankaferd hemostat twice for 2 min for 2 weeks. The sodium bicarbonate group brushed teeth at least 2 min a day and gargled with sodium bicarbonate 4 times for 2 min for 2 weeks. The Consolidated Standards of Reporting Trials diagram was used to illustrate the randomization of patients. RESULTS When the Ankaferd hemostat group is compared with the sodium bicarbonate group, there is a significant difference in favor of the Ankaferd hemostat group in the mucositis grade on the 7th day and 15th day after chemotherapy (p < 0.05). In the binary logistic regression analysis, among the factors affecting the formation of mucositis on the 7th day, only neutrophil and thyroid-stimulating hormone (TSH) were included in the model, while only the TSH variable is statistically significant. CONCLUSIONS It was determined that Ankaferd hemostat is effective in preventing oral mucositis due to chemotherapy in adult patients diagnosed with colorectal cancer. In addition, it has been suggested to conduct new studies on the effectiveness of Ankaferd hemostat in the prevention of mucositis in different groups. TRIAL REGISTRATION The study was registered at ClinicalTrials.gov (ID: NCT05438771, Date: 25.06.2022).

Association Between Alcohol Intake and Prostate Specific Antigen Screening: Results From a National Behavioral Survey. Urology 2022; 167:115-120. [PMID: 35772485 DOI: 10.1016/j.urology.2022.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 05/10/2022] [Accepted: 06/08/2022] [Indexed: 10/17/2022]
Abstract
OBJECTIVE To assess the association between self-reported alcohol use and prostate cancer (PCa) screening using the U.S.-based Behavioral Risk Factor Surveillance System (BRFSS) survey. MATERIALS AND METHODS A cross-sectional analysis of men aged between 55 and 69 who responded to the PSA screening and alcohol consumption portions of the 2018 BRFSS survey was performed. Alcohol consumption was assessed according with the Centers for Disease Control and Prevention definition of binge and heavy drinking. Rates of PSA screening between binge and non-binge drinkers and among heavy and non-heavy drinkers were compared. A complex weighted multivariable logistic regression model, adjusted for socio-economic covariates and weighted using BRFSS sample weights, was used to test the association between the self-reported alcohol use and the odds of PSA screening. RESULTS Among 57,774 men eligible for PCa screening, there were 8,276 binge drinkers with an unadjusted PSA screening prevalence of 37% versus 40% in the non-binge drinking group (P = .018). Among 3,836 heavy drinkers, the unadjusted PSA screening prevalence was 34% versus 40% in non-heavy drinkers (P < .001). In the multivariable analysis, only heavy drinking status was significantly associated with a lower odds of PSA screening (OR: 0.84, 95% CI: 0.72-0.98, P = .02). CONCLUSION Given that alcohol overuse may increase the risk of developing cancer, our finding of lower utilization of PCa screening among heavy drinkers is noteworthy. Efforts to support guideline-concordant cancer screening among heavy drinkers may represent an important strategy to reduce the burden of cancer in these men.

Abstract
Diabetes mellitus (DM), one of the metabolic diseases which is characterized by sustained hyperglycemia, is a life-threatening disease. The global prevalence of DM is on the rise, mainly in low- and middle-income countries. Diabetes is a major cause of blindness, heart attacks, kidney failure, stroke, and lower limb amputation. Type 2 diabetes mellitus (T2DM) is a form of diabetes that is characterized by high blood sugar and insulin resistance. T2DM can be prevented or delayed by a healthy diet, regular physical activity, maintaining normal body weight, and avoiding alcohol and tobacco use. Ethanol and its metabolites can cause differentiation defects in stem cells and promote inflammatory injury and carcinogenesis in several tissues. Recent studies have suggested that diabetes can be treated, and its consequences can be avoided or delayed with proper management. DM has a greater risk for several cancers, such as breast, colorectal, endometrial, pancreatic, gallbladder, renal, and liver cancer. The incidence of cancer is significantly higher in patients with DM than in those without DM. In addition to DM, alcohol abuse is also a risk factor for many cancers. We present a review of the recent studies investigating the association of both DM and alcohol abuse with cancer incidence.

Combined Effect of Secondhand Smoking and Alcohol Drinking on Risk of Persistent Human Papillomavirus Infection. BIOMED RESEARCH INTERNATIONAL 2019; 2019:5829676. [PMID: 31016192 PMCID: PMC6448343 DOI: 10.1155/2019/5829676] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Revised: 01/28/2019] [Accepted: 02/13/2019] [Indexed: 11/17/2022]
Abstract
Tobacco smoking is established as a cofactor of human papillomavirus (HPV) for cervical cancer risk. However, the role of secondhand smoking in cervical carcinogenesis is controversial. We aimed to assess the association between secondhand smoking and high risk- (HR-) HPV persistence, a pivotal event in development of cervical cancer. In total, 9,846 women who underwent health-screening examinations from 2002 to 2011 at the National Cancer Center, Korea, were included. Secondhand smoking was defined as being exposed to secondhand smoke at home or in the workplace. Multivariate logistic regression analysis was used to estimate the odds ratios (OR) and 95% confidence intervals (CIs) for risks of HR-HPV infection at baseline (N, 9,846, negative vs. positive), 1-year persistence (n, 1,237, 1-year negative vs. 1-year persistence), and 2-year persistence (n, 481, 2-year negative vs. 2-year persistence). Active smoking, secondhand smoking, and secondhand smoking in nonactive smokers had no association with these risks. Among alcohol drinkers, secondhand smoking in nonactive smokers had higher risks of HR-HPV infection at baseline (OR = 1.25, 95% CI = 1.05-1.48, p for multiplicative interaction = 0.003), 1-year persistence (1.75, 1.14-2.68, 0.004), and 2-year persistence (2.96, 1.42-6.15, 0.006), when compared to HR-HPV negative, 1-year negative, and 2-year negative categories, respectively. However, among nonalcohol drinkers, there was no association between smoking or secondhand smoking status and these risks. These findings suggest that women exposed to secondhand smoking at home or in the workplace might be at high risk of HR-HPV persistence when it is combined with alcohol drinking, even though neither active smoking nor secondhand smoking independently affects the risk.

Abstract
BACKGROUND There is inadequate evidence to determine whether there is an effect of alcohol consumption on lung cancer risk. We conducted a pooled analysis of data from the International Lung Cancer Consortium and the SYNERGY study to investigate this possible association by type of beverage with adjustment for other potential confounders. METHODS Twenty one case-control studies and one cohort study with alcohol-intake data obtained from questionnaires were included in this pooled analysis (19,149 cases and 362,340 controls). Adjusted odds ratios (OR) or hazard ratios (HR) with corresponding 95% confidence intervals (CI) were estimated for each measure of alcohol consumption. Effect estimates were combined using random or fixed-effects models where appropriate. Associations were examined for overall lung cancer and by histological type. RESULTS We observed an inverse association between overall risk of lung cancer and consumption of alcoholic beverages compared to non-drinkers, but the association was not monotonic. The lowest risk was observed for persons who consumed 10-19.9 g/day ethanol (OR vs. non-drinkers = 0.78; 95% CI: 0.67, 0.91), where 1 drink is approximately 12-15 g. This J-shaped association was most prominent for squamous cell carcinoma (SCC). The association with all lung cancer varied little by type of alcoholic beverage, but there were notable differences for SCC. We observed an association with beer intake (OR for ≥20 g/day vs nondrinker = 1.42; 95% CI: 1.06, 1.90). CONCLUSIONS Whether the non-monotonic associations we observed or the positive association between beer drinking and squamous cell carcinoma reflect real effects await future analyses and insights about possible biological mechanisms.

Abstract
The incidence of pancreatic cancer is on the rise. Risk factors for pancreatic cancer include alcohol toxicity and metabolic conditions such as obesity, hypertension, dyslipidaemia, insulin resistance and type 2 diabetes. However, the molecular mechanism by which chronic alcohol consumption contributes to pancreatic cancer is not well understood. The purpose of the study was to demonstrate the effects of long-term chronic ethanol exposure on the transformation of human pancreatic normal ductal epithelial (HPNE) cells. Our data showed that ethanol-transformed HPNE cells were more progressively transformed exhibiting spheroids and colonies, and anchorage-independent growth. These transformed cells contained high levels of reactive oxygen species and induced SATB2 expression. Furthermore, during ethanol-induced cellular transformation, cells gained the phenotypes of cancer stem cells (CSCs) by expressing pluripotency maintaining factors (Oct4, Sox2, cMyc and KLF4) and stem cell markers (CD24, CD44 and CD133). Ethanol-induced SATB2 can bind to the promoters of KLF4, Oct4, cMyc, Sox2, Bcl-2 and XIAP genes. Suppression of SATB2 expression in ethanol-transformed HPNE cells inhibited cell proliferation, colony formation and markers of CSCs and pluripotency. These data suggest that chronic alcohol consumption may contribute toward the development of pancreatic cancer by converting HPNE cells to cancer stem-like cells.

Abstract
Mammal embryos can be impaired by mother’s excessive ethanol uptake, which induces a higher level of reactive oxygen species (ROS) and interferes in one carbon unit metabolism. Here, our analysis by in vitro culture system reveals immediate effect of ethanol in medium on mouse embryo development presents concentration dependent. A preimplantation embryo culture using medium contained 1% ethanol could impact greatly early embryos development, and harmful effect of ethanol on preimplantation embryos would last during the whole development period including of reducing ratio of blastocyst formation and implantation, and deteriorating postimplantation development. Supplement of 50 μg/ml betaine into culture medium can effectively reduce the level of ROS caused by ethanol in embryo cells and rescue embryo development at each stage damaged by ethanol, but supplement of glycine can’t rescue embryo development as does betaine. Results of 5-methylcytosine immunodetection indicate that supplement of betaine into medium can reduce the rising global level of genome DNA methylation in blastocyst cells caused by 1% ethanol, but glycine can’t play the same impact. The current findings demonstrate that betaine can effectively rescue development of embryos harmed by ethanol, and possibly by restoring global level of genome DNA methylation in blastocysts.

HPV, KRAS mutations, alcohol consumption and tobacco smoking effects on esophageal squamous-cell carcinoma carcinogenesis. Int J Biol Markers 2018; 27:1-12.

Abstract
Esophageal squamous-cell carcinoma (ESCC) is an invasive neoplastic disease generally associated with poor survival rates. The incidence of ESCC is characterized by marked geographic variation, with highest rates noted in developing Southeastern African, Central and Eastern Asian countries. In the developed Western European and North American regions where there is a low disease incidence, heavy alcohol and cigarette consumption constitute major risk factors. The toxic effects of both these risk factors cause chronic irritation and inflammation of the esophageal mucosa, while at the cellular level they further confer mutagenic effects by the activation of oncogenes (e.g., RAS mutations), inhibition of tumor-suppressor genes, and profound DNA damage. Viral infections, particularly with human papillomavirus, may activate specific antiapoptotic, proliferative and malignant cellular responses that may be intensified in combination with the effects of alcohol and tobacco. In countries with a high ESCC incidence, low socioeconomic status and an inadequate diet of poorly preserved food are combined with basic nutritional deficiencies and inadequate medical treatment. These conditions are favorable to the above-mentioned risk factors implicated in ESCC development, which may be present and/or habitually used in certain populations. New perspectives in epidemiological studies of ESCC development and its risk factors allow genome-wide research involving specific environments and habits. Such research should consist of adequately large and representative samples, should use newly designed informative genetic markers, and apply genomic variation analysis of the functional transcripts involved in malignant cell cycle regulation and neoplastic transformation in the multi-step process of ESCC carcinogenesis.

Müller MF, Zhou Y, Adams DJ, Arends MJ. Effects of long-term ethanol consumption and Aldh1b1 depletion on intestinal tumourigenesis in mice. J Pathol 2017; 241:649-660. [PMID: 28026023 DOI: 10.1002/path.4869] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2016] [Revised: 12/16/2016] [Accepted: 12/21/2016] [Indexed: 12/20/2022]
Abstract
Ethanol and its metabolite acetaldehyde have been classified as carcinogens for the upper aerodigestive tract, liver, breast, and colorectum. Whereas mechanisms related to oxidative stress and Cyp2e1 induction seem to prevail in the liver, and acetaldehyde has been proposed to play a crucial role in the upper aerodigestive tract, pathological mechanisms in the colorectum have not yet been clarified. Moreover, all evidence for a pro-carcinogenic role of ethanol in colorectal cancer is derived from correlations observed in epidemiological studies or from rodent studies with additional carcinogen application or tumour suppressor gene inactivation. In the current study, wild-type mice and mice with depletion of aldehyde dehydrogenase 1b1 (Aldh1b1), an enzyme which has been proposed to play an important role in acetaldehyde detoxification in the intestines, received ethanol in drinking water for 1 year. Long-term ethanol consumption led to intestinal tumour development in wild-type and Aldh1b1-depleted mice, but no intestinal tumours were observed in water-treated controls. Moreover, a significant increase in DNA damage was detected in the large intestinal epithelium of ethanol-treated mice of both genotypes compared with the respective water-treated groups, along with increased proliferation of the small and large intestinal epithelium. Aldh1b1 depletion led to increased plasma acetaldehyde levels in ethanol-treated mice, to a significant aggravation of ethanol-induced intestinal hyperproliferation, and to more advanced features of intestinal tumours, but it did not affect intestinal tumour incidence. These data indicate that ethanol consumption can initiate intestinal tumourigenesis without any additional carcinogen treatment or tumour suppressor gene inactivation, and we provide evidence for a role of Aldh1b1 in protection of the intestines from ethanol-induced damage, as well as for both carcinogenic and tumour-promoting functions of acetaldehyde, including increased progression of ethanol-induced tumours.

Abstract
Excessive chronic alcohol consumption has become a worldwide health problem. The oncogenic effect of chronic alcohol consumption is one of the leading concerns. The mechanisms of alcohol-induced tumorigenesis and tumor progression are largely unknown, although many factors have been implicated in the process. This review discusses the recent progress in this research area with concentration on alcohol-induced dysregulation of cytokines and chemokines. Based on the available evidence, we propose that alcohol promotes tumor progression by the dysregulation of the cytokine/chemokine system. In addition, we discuss specific transcription factors and signaling pathways that are involved in the action of these cytokines/chemokines and the oncogenic effect of alcohol. This review provides novel insight into the mechanisms of alcohol-induced tumor promotion.

Abstract
Aims The aim of this study was to examine the effect of alcohol on the decidualization of human endometrial stromal cells during early pregnancy. Methods During in vitro decidualization, human endometrial stromal cells were treated with alcohol, 4-methylpyrazole hydrochloride (FPZ), the inhibitor of alcohol dehydrogenases (ADHs), and tetraethylthiuram disulfide (DSF), the inhibitor of acetaldehyde dehydrogenases (ALDHs), respectively. Cell viability and decidualization were examined. Apoptosis and proliferation were also evaluated. Results The findings showed that ADHs and ALDHs were up-regulated during decidualization. After alcohol treatment, the cell viability of decidual stromal cells was significantly higher than control, which was abrogated by FPZ or DSF. When cells were treated with alcohol, proliferation-related signal pathways were up-regulated in decidualized cells. Additionally, FOXO1 transcriptionally up-regulates ADH1B. Conclusion Our study provided an evidence that highly expressed ADHs and ALDHs endow decidual stromal cells an ability to alleviate the harm from alcohol.

Abstract
BACKGROUND Alcohol intake may increase the risk of prostate cancer (PCa). Many previous studies harbored important methodological limitations. METHODS We conducted a population-based case-control study of PCa comprising 1933 cases and 1994 controls in Montreal, Canada. Lifetime alcohol consumption was elicited, by type of beverage, during in-person interviews. Odds ratios (OR) and 95% confidence intervals (CI) assessed the association between alcohol intake and PCa risk, adjusting for potential confounders and considering the subjects' PCa screening history. RESULTS We observed a weak, non-significant positive association between high consumption of total alcohol over the lifetime and risk of high-grade PCa (OR=1.18, 95% CI 0.81-1.73). Risk estimates were more pronounced among current drinkers (OR=1.40, 95%CI 1.00-1.97), particularly after adjusting for the timing of last PCa screening (OR=1.52, 95%CI 1.07-2.16). These associations were largely driven by beer consumption. The OR for high-grade PCa associated with high beer intake was 1.37 (95%CI 1.00-1.89); it was 1.49 (95%CI 0.99-2.23) among current drinkers and 1.68 (95% CI 1.10-2.57) after adjusting for screening recency. High cumulative consumption of spirits was associated with a lower risk of low-grade PCa (OR=0.75, 95%CI 0.60-0.94) but the risk estimate no longer achieved statistical significance when restricting to current users. No association was found for wine consumption. CONCLUSION Findings add to the accumulating evidence that high alcohol consumption increases the risk of high-grade PCa. This association largely reflected beer intake in our population, and was strengthened when taking into account PCa screening history.

Abstract
BACKGROUND Studies on the association between alcohol consumption and colorectal cancer (CRC) prognosis have yielded inconsistent results. OBJECTIVE The associations of lifetime and 1-y prediagnostic alcohol consumption with relevant prognostic outcomes were evaluated in a large population-based cohort of CRC patients. DESIGN In 2003-2010, 3121 patients diagnosed with CRC were interviewed on sociodemographic and lifestyle factors, medication, and comorbidities. Cancer recurrence, vital status, and cause of death were documented for a median follow-up time of 4.8 y. With the use of Cox proportional hazard regression, associations between lifetime and recent alcohol consumption and overall, CRC-specific, recurrence-free, and disease-free survival were analyzed. RESULTS In this patient cohort with a median age of 69 y at diagnosis, lifetime abstainers showed poorer overall [adjusted HR (aHR): 1.25; 95% CI: 1.03, 1.52] and CRC-specific (aHR: 1.37; 95% CI: 1.10, 1.70) survival than lifetime light drinkers (women: >0-12 g/d; men: >0-24 g/d). Lifetime heavy drinkers showed poorer overall (aHR: 1.37; 95% CI: 1.06, 1.78) and disease-free (aHR: 1.38; 95% CI: 1.09, 1.74) survival. Alcohol abstaining in the year before diagnosis was associated with poorer overall (aHR: 1.42; 95% CI: 1.20, 1.68), CRC-specific (aHR: 1.38; 95% CI: 1.13, 1.68), and disease-free (aHR: 1.23; 95% CI: 1.05, 1.44) survival. Lifetime abstainers with nonmetastatic disease showed poorer CRC-specific (aHR: 1.48; 95% CI: 1.10, 2.00) and recurrence-free (aHR: 1.32; 95% CI: 1.02, 1.70) survival. Wine abstaining but not beer or liquor abstaining was associated with poorer survival. Associations between alcohol consumption and prognosis varied according to presence of diabetes and age. CONCLUSIONS Prediagnostic alcohol abstaining and heavy drinking were associated with poorer survival after a CRC diagnosis than light drinking. The protective effects of light consumption might be restricted to wine, and associations might differ according to age and presence of diabetes mellitus.

Abstract
Diet may play a role in both promoting and inhibiting human breast cancer development. In this review, nutritional risk factors such as consumption of dietary fat, meat, fiber, and alcohol, and intake of phytoestrogen, vitamin D, iron, and folate associated with breast cancer are reviewed. These nutritional factors have a variety of associations with breast cancer risk. Type of fat consumed has different effects on risk of breast cancer: consumption of meat is associated with heterocyclic amine (HCA) exposure; different types of plant fiber have various effects on breast cancer risk; alcohol consumption may increase the risk of breast cancer by producing acetaldehyde and reactive oxygen species (ROS); intake of phytoestrogen may reduce risk of breast cancer through genomic and non-genomic action; vitamin D can reduce the risk of breast cancer by inhibiting the process of cancer invasion and metastasis; intake of dietary iron may lead to oxidative stress, DNA damage, and lipid peroxidation; and lower intake of folate may be linked to a higher risk of breast cancer.

Abstract
A previous study indicated that MLL3 genetic polymorphisms were associated with human cancer. However, whether MLL3 genetic variants are associated with the risk of laryngeal cancer is not clear. This study investigated the association between MLL3 gene polymorphisms and laryngeal cancer in a Chinese population. Four polymorphisms of the MLL3 gene (rs6943984, rs4725443, rs3800836, rs6464211) were genotyped using the TaqMan method in 592 patients with larynx cancer and 602 age- and sex-matched noncancer controls. We found that rs6943984 and rs4725443 of the MLL3 gene were significantly associated with the risk of larynx cancer after Bonferroni correction. The minor allele A for rs6943984 was associated with increased larynx cancer risk (P < 0.001, OR = 1.960, 95% CI = 1.587-2.420). C allele frequency (0.151) for rs4725443 was significantly higher in the case group than the control group (0.072, P < 0.001). Haplotype analyses showed that haplotypes A-T-A-C and G-T-G-C increased the risk of laryngeal cancer (OR = 2.406, 95% CI: 1.820-3.180, P < 0.001; OR = 1.399, 95% CI: 1.180-1.659, respectively), and haplotypes G-T-A-C and G-T-G-T significantly reduced the risk of laryngeal cancer (OR = 0.332, 95% CI: 0.271-0.408, P < 0.001; OR = 0.742, 95% CI: 0.607-0.908, respectively). We also found that MLL3 rs6943984 and rs4725443 polymorphisms had synergistic effects with smoking or alcohol drinking for the risk of laryngeal cancer. This study indicated that MLL3 genetic polymorphisms and haplotypes were associated with larynx cancer in a Chinese population. There was a mutually synergistic effect between smoking, alcohol drinking, and MLL3 gene polymorphisms for laryngeal cancer.

Inhibition of diethylnitrosamine-initiated alcohol-promoted hepatic inflammation and precancerous lesions by flavonoid luteolin is associated with increased sirtuin 1 activity in mice. Hepatobiliary Surg Nutr 2015; 4:124-34. [PMID: 26005679 DOI: 10.3978/j.issn.2304-3881.2014.08.06] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2014] [Accepted: 09/21/2014] [Indexed: 12/12/2022]
Abstract
BACKGROUND Chronic and excessive alcohol consumption is an established risk for hepatic inflammation and carcinogenesis. Luteolin is one of the most common flavonoids present in plants and has potential beneficial effects against cancer. In this study, we examined the effect and potential mechanisms of luteolin supplementation in a carcinogen initiated alcohol-promoted pre-neoplastic liver lesion mouse model. METHODS C57BL/6 mice were injected with diethylnitrosamine (DEN) [i.p. 25 mg/kg of body weight (BW)] at 14 days of age. At 8 weeks of age mice were group pair-fed with Lieber-DeCarli liquid control diet or alcoholic diet [ethanol (EtOH) diet, 27% total energy from ethanol] and supplemented with a dose of 30 mg luteolin/kg BW per day for 21 days. RESULTS DEN-injected mice fed EtOH diet displayed a significant induction of pre-neoplastic lesions, a marker associated with presence of steatosis and inflammation. Dietary luteolin significantly reduced the severity and incidence of hepatic inflammatory foci and steatosis in DEN-injected mice fed EtOH diet, as well the presence of preneoplastic lesions. There was no difference on hepatic protein levels of sirtuin 1 (SIRT1) among all groups; however, luteolin supplementation significantly reversed alcohol-reduced SIRT1 activity assessed by the ratio of acetylated and total forkhead box protein O1 (FoXO1) and SIRT1 target proliferator-activated receptor gamma, coactivator 1 alpha (PGC1α). CONCLUSIONS Dietary intake of luteolin prevents alcohol promoted pre-neoplastic lesions, potentially mediated by SIRT1 signaling pathway.

Abstract
Alcohol consumption is a possible co-factor of high-risk human papillomavirus (HR-HPV) persistence, a major step in cervical carcinogenesis, but the association between alcohol and continuous HPV infection remains unclear. This prospective study identified the association between alcohol consumption and HR-HPV persistence. Overall, 9230 women who underwent screening during 2002-2011 at the National Cancer Center, Korea were analysed in multivariate logistic regression. Current drinkers [odds ratio (OR) 2·49, 95% confidence interval (CI) 1·32-4·71] and drinkers for ⩾5 years (OR 2·33, 95% CI 1·17-4·63) had a higher risk of 2-year HR-HPV persistence (HPV positivity for 3 consecutive years) than non-drinkers and drinkers for <5 years, respectively (vs. HPV negativity for 3 consecutive years). A high drinking frequency (⩾twice/week) and a high beer intake (⩾3 glasses/occasion) had higher risks of 1-year (OR 1·80, 95% CI 1·01-3·36) HPV positivity for 2 consecutive years) and 2-year HR-HPV persistence (OR 3·62, 95% CI 1·35-9·75) than non-drinkers. Of the HPV-positive subjects enrolled, drinking habit (OR 2·68, 95% CI 1·10-6·51) and high consumption of beer or soju (⩾2 glasses/occasion; OR 2·90, 95% CI 1·06-7·98) increased the risk of 2-year consecutive or alternate HR-HPV positivity (vs. consecutive HPV negativity). These findings suggest that alcohol consumption might increase the risk of cervical HR-HPV persistence in Korean women.

Abstract
PRIMARY OBJECTIVE Research has identified certain foods and dietary patterns that are associated with reduced cancer risk and improved survival after cancer diagnosis. This research has formed the basis for dietary guidance issued by cancer organizations. Unfortunately, gaps within nutrition research have made it difficult to make recommendations in some areas. This review specifies suggested dietary guidance in which evidence of a dietary influence on cancer risk is substantial, even if not conclusive. Evidence summaries within the review are based on the 2007 report of the World Cancer Research Fund/American Institute for Cancer Research. This review also describes advantages and disadvantages of following the suggested dietary guidance and includes putative mechanisms involved in cancer progression. MAIN OUTCOMES AND RESULTS Suggested dietary guidance where evidence is sufficiently compelling include (1) limiting or avoiding dairy products to reduce the risk of prostate cancer; (2) limiting or avoiding alcohol to reduce the risk of cancers of the mouth, pharynx, larynx, esophagus, colon, rectum, and breast; (3) avoiding red and processed meat to reduce the risk of cancers of the colon and rectum; (4) avoiding grilled, fried, and broiled meats to reduce the risk of cancers of the colon, rectum, breast, prostate, kidney, and pancreas; (5) consumption of soy products during adolescence to reduce the risk of breast cancer in adulthood and to reduce the risk of recurrence and mortality for women previously treated for breast cancer; and (6) emphasizing fruits and vegetables to reduce risk of several common forms of cancer. CONCLUSION By adopting the precautionary principle for nutrition research, this review aims to serve as a useful tool for practitioners and patients.

Abstract
BORIS is a paralog of a highly conserved, multi-functional chromatin factor CTCF. Unlike CTCF, which has been shown to possess tumor-suppressive properties, BORIS belongs to the "cancer/testis antigen" family normally expressed only in germ cells and aberrantly activated in a variety of tumors. The consequences of BORIS expression, relative abundance of its isoforms, and its role in carcinogenesis have not been completely elucidated. It activates transcription of hTERT and MYC, genes relevant for laryngeal carcinoma progression. In this study, BORIS expression has been analyzed at the transcriptional level by RT-PCR and protein level by semi-quantitative immunohistochemistry in 32 laryngeal squamous cell carcinomas and adjacent non-tumorous tissue. BORIS was detected in 44 % (14/32) laryngeal squamous cell carcinoma samples, while it was detected only in one normal, tumor-adjacent tissue sample. Tree based survival analysis, using the recursive partitioning algorithm mvpart, extracted the ratio of relative abundance of BORIS transcript variants containing exon 7 (BORIS 7+) and those lacking exon 7 (BORIS 7-) as an independent prognostic factor associated with disease relapse during a 5-year follow-up period. Patients having BORIS 7+/BORIS 7- ratio ≥1 had a higher rate of disease relapse than patients with BORIS 7+/BORIS 7- ratio <1. Hazard ratio for that group, based on Cox Proportional Hazard Regression, was 3.53. This is the first study analyzing expression of BORIS protein and transcript variants in laryngeal squamous cell carcinoma relative to its possible prognostic value for recurrence and overall survival.

The influence of B-complex vitamins upon the prolongation of prothrombin time by acetaldehyde. Blood Coagul Fibrinolysis 2013; 24:477-83.

Abstract
Alcoholism plays a major role in the insufficient utilization or deficiency of the vitamin B-complex molecules, and the pathologies resulting therefrom. Thiamine, pyridoxamine, and folic acid, each contain primary amine functional groups, whereas nicotinamide and vitamin B12 contain amide groups, each of which are potential reactants with acetaldehyde (AcH), the primary intermediate in the metabolism of ethanol. In this current study, it is reported that prothrombin time (PT), which is prolonged in a fraction of the alcoholic population, can be modified (in the laboratory) when several B-complex vitamins and AcH are added successively to human plasma or are premixed prior to the addition to plasma. Particularly, thiamine, pyridoxamine, and folic acid, at 0.01 mol/l, when added successively with 44.7 mmol/l AcH to plasma, or when premixed prior to addition to plasma, produced a marked reduction in the anticoagulant effect of AcH. Nicotinamide had no effect on PT nor did mixtures with AcH effect PT. However, NAD, which contains a primary amine in its AMP moiety, reacted with AcH, lowering the latter's anticoagulant activity upon addition to plasma. Vitamin B12 did not affect PT. Interestingly, successive mixtures of vitamin B12 and AcH to plasma resulted in a small but statistically significant increase (P≤0.05) in the anticoagulant effect of AcH, whereas premixtures had no statistically significant effect (P>0.05). The decrease in anticoagulant activity of AcH in the presence of B-complex vitamins and NAD suggests that the primary amines in these molecules may form Schiff bases with AcH, thereby lowering both the free AcH concentration as well as the ability of the free vitamins/coenzymes to partake in essential physiological reactions.

Abstract
Alcohol-mediated cancers represent more than 3.5% of cancer-related deaths, yet how alcohol promotes cancer is a major open question. Using Drosophila, we identified novel interactions between dietary ethanol and loss of tumor suppressor components of the Hippo Pathway. The Hippo Pathway suppresses tumors in flies and mammals by inactivating transcriptional co-activator Yorkie, and the spectrum of cancers associated with impaired Hippo signaling overlaps strikingly with those associated with alcohol. Therefore, our findings may implicate loss of Hippo Pathway tumor suppression in alcohol-mediated cancers. Ethanol enhanced overgrowth from loss of the expanded, hippo, or warts tumor suppressors but, surprisingly, not from over-expressing the yorkie oncogene. We propose that in parallel to Yorkie-dependent overgrowth, impairing Hippo signaling in the presence of alcohol may promote overgrowth via additional alcohol-relevant targets. We also identified interactions between alcohol and Hippo Pathway over-activation. We propose that exceeding certain thresholds of alcohol exposure activates Hippo signaling to maintain proper growth control and prevent alcohol-mediated mis-patterning and tissue overgrowth.

Abstract
S-adenosyl methionine (SAM) is a key intermediate in the metabolism of sulfur amino acids and is a major methyl donor in the cell. Although the low plasma level of SAM has been associated with atherosclerosis, the effect of SAM administration on atherosclerosis is not known. Endothelial dysfunction is an early prerequisite for atherosclerosis. This study was undertaken to investigate the possible preventive effect of SAM on endothelial dysfunction and the molecular mechanism of its action. SAM treatment prevented endothelial dysfunction in high fat diet (HFD)-fed rats. In cultured human aortic endothelial cells, linoleic acid (LA) increased and SAM decreased cell apoptosis and endoplasmic reticulum stress. Both LA and SAM increased heme oxygenase-1 (HO-1) expression in an NF-E2-related factor 2-dependent manner. However, knockdown of HO-1 reversed only the SAM-induced preventive effect of cell apoptosis. The LA-induced HO-1 expression was dependent on PPARα, whereas SAM induced HO-1 in a PPAR-independent manner. These data demonstrate that SAM treatment prevents endothelial dysfunction in HFDfed animals by inducing HO-1 in vascular endothelial cells. In cultured endothelial cells, SAM-induced HO-1 was responsible for the observed prevention of cell apoptosis. We propose that SAM treatment may represent a new therapeutic strategy for atherosclerosis.

Abstract
Although in the United States the incidence of oral and pharyngeal cancer (OPC) has been significantly higher in men than in women, the identification of human papilloma virus as a risk factor for OPC has focused new scrutiny on who may develop OPC. One surprising element is that non-Hispanic white women have a higher incidence of OPC than of cervical cancer. OPC is thus a woman's disease, and diligence is needed to ensure that the occurrence of OPC in women does not go undetected by their oral health care providers.

Abstract
Folates are associated with a variety of human health benefits, while folate deficiency has been identified as a potential risk factor for many health problems and cancers, due to its role in dysregulation of DNA synthesis, repair and methylation. The US Food and Drug Administration adopted requirements for folate fortification in some food products, which has resulted in an increase in mean dietary folate intake and a concomitant reduction in the incidence of adverse health effects associated with folate deficiency. This includes a significant reduction in the incidence of folate deficiency-associated birth defects, such as spina bifida.

Abstract
The tumour suppressor APC is the most commonly altered gene in colorectal cancer (CRC). Genetic and epigenetic alterations of APC may therefore be associated with dietary and lifestyle risk factors for CRC. Analysis of APC mutations in the extended mutation cluster region (codons 1276-1556) and APC promoter 1A methylation was performed on 185 archival CRC samples collected from participants of the European Prospective Investigation into Cancer (EPIC)-Norfolk study, with the aim of relating these to high-quality seven-day dietary and lifestyle data collected prospectively. Truncating APC mutations (APC(+) ) and promoter 1A methylation (PM(+) ) were identified in 43% and 23% of CRCs analysed, respectively. Distal CRCs were more likely than proximal CRCs to be APC(+) or PM(+) (p = 0.04). APC(+) CRCs were more likely to be moderately/well differentiated and microsatellite stable than APC(-) CRCs (p = 0.05 and 0.03). APC(+) CRC cases consumed more alcohol than their counterparts (p = 0.01) and PM(+) CRC cases consumed lower levels of folate and fibre (p = 0.01 and 0.004). APC(+) or PM(+) CRC cases consumed higher levels of processed meat and iron from red meat and red meat products (p = 0.007 and 0.006). Specifically, CRC cases harbouring GC-to-AT transition mutations consumed higher levels of processed meat (35 versus 24 g/day, p = 0.04) and iron from red meat and red meat products (0.8 versus 0.6 mg/day, p = 0.05). In a logistic regression model adjusted for age, sex and cigarette-smoking status, each 19 g/day (1SD) increment increase in processed meat consumption was associated with cases with GC-to-AT mutations (OR 1.68, 95% CI 1.03-2.75). In conclusion, APC(+) and PM(+) CRCs may be influenced by diet and GC-to-AT mutations in APC are associated with processed meat consumption, suggesting a mechanistic link with dietary alkylating agents, such as N-nitroso compounds.

Abstract
There has been a dramatic enhancement of the reported incidence of autism in different parts of the world over the last 30 years. This can apparently not be explained only as a result of improved diagnosis and reporting, but may also reflect a real change. The causes of this change are unknown, but if we shall follow T.C. Chamberlin's principle of multiple working hypotheses, we need to take into consideration the possibility that it partly may reflect an enhancement of the average frequency of responsible alleles in large populations. If this hypothesis is correct, it means that the average germline mutation rate must now be much higher in the populations concerned, compared with the natural mutation rate in hominid ancestors before the agricultural and industrial revolutions. This is compatible with the high prevalence of impaired human semen quality in several countries and also with what is known about high levels of total exposure to several different unnatural chemical mutagens, plus some natural ones at unnaturally high levels. Moreover, dietary deficiency conditions that may lead to enhancement of mutation rates are also very widespread, affecting billions of people. However, the natural mutation rate in hominids has been found to be so high that there is apparently no tolerance for further enhancement of the germline mutation rate before the Eigen error threshold will be exceeded and our species will go extinct because of mutational meltdown. This threat, if real, should be considered far more serious than any disease causing the death only of individual patients. It should therefore be considered the first and highest priority of the best biomedical scientists in the world, of research-funding agencies and of all medical doctors to try to stop the express train carrying all humankind as passengers on board before it arrives at the end station of our civilization.

Abstract
BACKGROUND Although the primary risk factors for developing oral cancers are well understood, less is known about the relationship among the secondary factors that may modulate the progression of oral cancers, such as high-risk human papillomavirus (HPV) infection and folic acid (FA) supplementation. This study examined high-risk HPV and FA supplementation effects, both singly and in combination, to modulate the proliferative phenotypes of the oral cancer cell lines CAL27, SCC25 and SCC15. RESULTS Using a comprehensive series of integrated in vitro assays, distinct effects of HPV infection and FA supplementation were observed. Both high-risk HPV strains 16 and 18 induced robust growth-stimulating effects in CAL27 and normal HGF-1 cells, although strain-specific responses were observed in SCC25 and SCC15 cells. Differential effects were also observed with FA administration, which significantly altered the growth rate of the oral cancer cell lines CAL27, SCC15, and SCC25, but not HGF-1 cells. Unlike HPV, FA administration induced broad, general increases in cell viability among all cell lines that were associated with p53 mRNA transcriptional down-regulation. None of these cell lines were found to harbor the common C677T mutation in methylenetetrahydrofolate reductase (MTHFR), which can reduce FA availability and may increase oral cancer risk. CONCLUSION Increased FA utilization and DNA hypermethylation are common features of oral cancers, and in these cell lines, specifically. The results of this study provide further evidence that FA antimetabolites, such as Fluorouracil (f5U or 5-FU) and Raltitrexed, may be alternative therapies for tumors resistant to other therapies. Moreover, since the incidence of oral HPV infection has been increasing, and can influence oral cancer growth, the relationship between FA bioavailability and concomitant HPV infection must be elucidated. This study is among the first pre-clinical studies to evaluate FA- and HPV-induced effects in oral cancers, both separately and in combination, which provides additional rationale for clinical screening of HPV infection prior to treatment.

Abstract
This study examined the association between consumption of alcoholic beverages and all-cause and cardiovascular disease (CVD) mortality in a cohort of men (n = 31,367). In the Cox proportional hazards model adjusted for age, year of examination, body mass index (BMI), smoking, family history of CVD, and aerobic fitness, there were no significant differences in risk of all-cause mortality across alcohol intake groups. Risk of CVD mortality was reduced 29% in quartile 1 (HR = 0.71, 95% confidence interval (CI): 0.53, 0.95) and 25% in quartile 2 (HR = 0.75, 95% CI: 0.58, 0.98). The amount of alcohol consumed to achieve this risk reduction was <6 drinks/week; less than the amount currently recommended. The addition of other potential confounders and effect modifiers including blood pressure, insulin sensitivity, lipid levels, and psychological variables did not affect the magnitude of association. Future research is needed to validate the current public health recommendations for alcohol consumption.

Abstract
Controversial studies from others suggested that alcohol intake could be associated with some deleterious effects in the uterus. Not all the effects of alcohol drinking on female reproductive organs can be explained in terms of endocrine disturbances. Deleterious effect of alcohol or its metabolites in situ could also play a role. Accordingly, we found a metabolism of alcohol to acetaldehyde in the rat uterine horn tissue cytosolic fraction mediated by xanthine oxidoreductase, requiring a purine cosubstrate and inhibited by allopurinol. This activity was detected by histochemistry in the epithelium and aldehyde dehydrogenase activity was detected in the muscular layer and in the serosa. There was a microsomal process, not requiring NADPH and of enzymatic nature, oxygen-dependent and inhibited by diethyldithiocarbamate, diphenyleneiodonium and partially sensitive to esculetin and nordihydroguaiaretic acid. The presence of metabolic pathways in the uterine horn able to generate acetaldehyde, accompanied by a low capacity to destroy it through aldehyde dehydrogenase, led to acetaldehyde accumulation in the uterus during ethanol exposure. Results suggest that any acetaldehyde produced in situ or arriving to the uterine horn via blood would remain in this organ sufficiently to have the opportunity to react with critical molecules to cause deleterious effects.

Abstract
We previously reported that the microsomal fraction from rat mammary tissue is able to oxidize ethanol to acetaldehyde, a mutagenic-carcinogenic metabolite, depending on the presence of NADPH and oxygen but not inhibited by carbon monoxide or other cytochrome P450 inhibitors. The process was strongly inhibited by diphenyleneiodonium, a known inhibitor of NADPH oxidase, and by nordihydroguaiaretic acid, an inhibitor of lipoxygenases. This led us to suggest that both enzymes could be involved. With the purpose of identifying natural compounds present in food with the ability to decrease the production of acetaldehyde in mammary tissue, in the present studies, several plant polyphenols having inhibitory effects on lipoxygenases and of antioxidant nature were tested as potential inhibitors of the rat mammary tissue microsomal pathway of ethanol oxidation. We included in the present screening study 32 polyphenols having ready availability and that were also tested against the rat mammary tissue cytosolic metabolism of ethanol to acetaldehyde. Several polyphenols were also able to inhibit the microsomal ethanol oxidation at concentrations as low was 10-50 μM. The results of these screening experiments suggest the potential of several plant polyphenols to prevent in vivo production and accumulation of acetaldehyde in mammary tissue.

Abstract
BACKGROUND The relationship between alcohol and cancer death has not been well established in Asian population, particularly among women. METHOD We evaluated the association between alcohol consumption and all-cause and cancer mortality in a large-scale prospective study of 1,341,393 Korean men and women aged 40-69 years who participated in health examination in 2000. After 5 years follow-up for mortality (2001-2005), 19,375 deaths were identified, and Cox regression was used for longitudinal analyses. RESULTS The J-shaped relationship between alcohol consumption and all-cause and all-cancer mortality was found in men. However, heavy drinking was positively associated with the risk of all-cause and all-cancer mortality in men and women. Alcohol consumption was positively associated with the risk of cancer mortality such as cancers of liver, stomach, colorectal, prostate, esophageal, brain, and larynx and cancer of lips, oral cavity, pharynx in men and increased the risk of all-cancer and colorectal cancer mortality in women. Kidney cancer mortality was inversely associated with alcohol consumption in men. CONCLUSION Heavy drinking showed an increased mortality risk of all-cause, all-cancer, and several cancers in men and women. There was no favorable effect of light drinking on all-cause and all-cancer mortality for women.

Abstract
BACKGROUND The aim of this cohort study was to quantify the effect of alcohol on the risk of oral cancer in different strata of folate intake, controlling for known confounders. METHODS A cohort of 87,621 women in the Nurses' Health Study was followed up from 1980 to 2006, and 147 incident oral cancer cases were reported and confirmed. Data on alcohol intake and diet were obtained through self-reported food frequency questionnaires every 4 years. Cox proportional regression analysis was conducted to estimate the adjusted risk ratios (RR) and 95% confidence intervals (95% CI). RESULTS When compared with nondrinkers, the adjusted RRs (95% CIs) for alcohol intake were 0.59 (0.39-0.87) for 0.1-14.9 g/d, 1.15 (0.67-1.97) for 15-29.9 g/d, and 1.92 (1.08-3.40) for ≥30 g/d. We observed a significant interaction between alcohol and folate intakes (P = 0.02). The cancer risk for subjects with high alcohol (≥30 g/d) and low folate (<350 μg/d) intakes was significantly elevated (RR, 3.36; 95% CI, 1.57-7.20) as compared with nondrinkers with low folate intake. The risk associated with high alcohol intake (≥30 g/d) was reduced to 0.98 (0.35-2.70) in the high-folate (≥350 μg/d) group as compared with nondrinkers with high folate intake. CONCLUSIONS High alcohol intake is associated with significantly increased oral cancer risk, especially in women with low folate intake. IMPACT A significant interaction between alcohol and folate intakes seems to affect oral cancer risk in women, a finding with potential public health utility.

Abstract
The tumour suppressor p53 is one of the most commonly altered genes in colorectal cancer (CRC) development. Genetic alterations in p53 may therefore be associated with postulated lifestyle risk factors for CRC, such as red meat consumption. In the European Prospective Investigation into Cancer and Nutrition-Norfolk study, we examined whether detailed estimates of dietary and lifestyle factors measured at baseline related to later development of p53 mutations in CRCs. After 10-year follow-up, there were 185 incident CRCs of which 34% had somatic p53 mutations (p53+). We observed significantly higher mean intakes of alcohol, total meat and red meat, in the group with p53 mutations and advanced Dukes' stage disease (daily alcohol intake was 7 and 12 g for p53- and p53+ cases, respectively, P = 0.04; daily total meat intake was 69 and 100 g for p53- and p53+ cases, respectively, P = 0.03 and daily red meat intake was 39 and 75 g for p53- and p53+ cases, respectively, P = 0.01). Each 50 g/day increment in total meat intake was associated with having p53 mutations in cases with advanced Dukes' stages [odds ratio (OR): 3.43, 95% confidence interval (CI): 1.47-7.96]. Similarly, each 50 g/day increment in red meat intake was also significantly associated with having consistent p53 mutations in cases with advanced Dukes' stages (OR: 2.42, 95% CI: 1.18-4.96). These effects of total meat or red meat intake and advanced Dukes' stages were independent of age, sex, body mass index, smoking and alcohol intake. Furthermore, P values for interaction between daily total meat or red meat intake and Dukes' stages were statistically significant in multivariable models (Pinteraction < 0.001). Our results suggest that p53 mutations accelerate progression of CRC to advanced Dukes' stage in association with higher meat especially red meat intakes.

Abstract
Objectives To examine the primary risk factor for oral cancer in the US, smoking and tobacco use, among the specific US states that experienced short-term increases in oral cancer incidence and mortality. Methods Population-based data on oral cancer morbidity and mortality in the US were obtained from the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) database for analysis of recent trends. Data were also obtained from the Centers for Disease Control and Prevention (CDC) Behavioral Risk Factor Surveillance System (BRFSS) to measure current and former trends of tobacco usage. To comprehensive measures of previous state tobacco use and tobacco-related policies, the Initial Outcomes Index (IOI, 1992-1993) and the Strength of Tobacco Control index (SoTC, 1999-2000) were also used for evaluation and comparison. Results Analysis of the NCI-SEER data confirmed a previous report of geographic increases in oral cancer and demonstrated these were state-specific, were not regional, and were unrelated to previously observed increases among females and minorities. Analysis of the CDC-BRFSS data revealed these states had relatively higher percentages of smokers currently, as well as historically. In addition, analysis of the IOI and SoTC indexes suggest that many factors, including cigarette pricing, taxes and home or workplace bans, may have had significant influence on smoking prevalence in these areas. Trend analysis of these data uncovered a recent and significant reversal in smoking rates that suggest oral cancer incidence and mortality may also begin to decline in the near future. Conclusion Due to the rising costs of health care in the US and the limited resources available for health prevention efforts, it is essential to organize and direct more effective efforts by public health officials and epidemiologists, as well as funding from local, state and federal governments, to reduce and eliminate identified health disparities. This study provides evidence how these efforts may be directed to specific geographic areas, and towards the white males, previously thought to be unaffected by the increases in oral cancer among females and minorities.

Abstract
BACKGROUND Little is known about the relationship between alcohol intake and breast cancer risk among Mexican women. This association may be modified by folate and Vitamin B12. METHODS A population-based case-control study conducted in Mexico recruited 1,000 incident breast cancer cases aged 35-69 and 1,074 controls matched on age, region, and health care system. In-person interviews were conducted to assess breast cancer risk factors and recent diet using a food frequency questionnaire. Conditional logistic regression models estimated adjusted odds ratios and 95% confidence intervals. RESULTS Over one-half (57%) of cases and less than one-half of controls (45%) reported any lifetime alcohol consumption. Compared with never drinkers, women reporting ever drinking (Adjusted OR = 1.25, 95% CI = 0.99-1.58) had a greater odds of breast cancer. There was evidence for interaction in the association between ever consuming any alcohol and breast cancer by folate (p for interaction = 0.04) suggesting women with lower folate intake had a higher odds of breast cancer (Adjusted OR = 1.99, 95% CI = 1.26-3.16) compared to women with higher folate intake (OR = 1.12, 95% CI = 0.69-1.83). CONCLUSIONS Our findings support evidence that any alcohol intake increases risk of breast cancer. Insufficient intake of folate may further elevate risk for developing breast cancer among women who consume alcohol.

Abstract
BACKGROUND Current research is inconclusive regarding the relation between alcohol consumption and prostate cancer risk. In this study, the authors examined the associations of total alcohol, type of alcoholic beverage, and drinking pattern with the risk of total, low-grade, and high-grade prostate cancer. METHODS Data for this study came from the 2129 participants in the Prostate Cancer Prevention Trial (PCPT) who had cancer detected during the 7-year trial and 8791 men who were determined by biopsy to be free of cancer at the trial end. Poisson regression was used to calculate relative risks (RRs) and 95% confidence intervals (95% CIs) for associations of alcohol intake with prostate cancer risk. RESULTS Associations of drinking with high-grade disease did not differ by treatment arm. In combined arms, heavy alcohol consumption (> or =50 g of alcohol daily) and regular heavy drinking (> or =4 drinks daily on > or =5 days per week) were associated with increased risks of high-grade prostate cancer (RR, 2.01 [95% CI, 1.33-3.05] and 2.17 [95% CI, 1.42-3.30], respectively); less heavy drinking was not associated with risk. Associations of drinking with low-grade cancer differed by treatment arm. In the placebo arm, there was no association of drinking with risk of low-grade cancer. In the finasteride arm, drinking > or =50 g of alcohol daily was associated with an increased risk of low-grade disease (RR, 1.89; 95% CI, 1.39-2.56); this finding was because of a 43% reduction in the risk of low-grade cancer attributable to finasteride treatment in men who drank <50 g of alcohol daily and the lack of an effect of finasteride in men who drank > or =50 g of alcohol daily (P(interaction) = .03). CONCLUSIONS Heavy, daily drinking increased the risk of high-grade prostate cancer. Heavy drinking made finasteride ineffective for reducing prostate cancer risk.

Abstract
BACKGROUND In pancreatic ductal adenocarcinoma (PDA), evidence on the etiopathogenic role of alcohol consumption in the occurrence of K-ras mutations is scant, and the role of alcohol in pancreatic carcinogenesis is not well established. We analyzed the relation between lifetime consumption of alcohol and mutations in codon 12 of the K-ras oncogene in patients with PDA. METHODS Incident cases of PDA were prospectively identified and interviewed face-to-face during hospital admission about lifetime alcohol consumption and other lifestyle factors. Logistic regression was used to compare PDA cases (N = 107) with mutated and wild-type K-ras tumors (case-case study). RESULTS Mutated cases were moderate or heavy drinkers more frequently than wild-type cases: the odds ratio adjusted by age, sex, smoking, and history of pancreatitis (ORa) was 3.18 (95% confidence interval: 1.02-9.93; P = 0.046). Total grams of alcohol and years of consumption were higher in mutated than in wild-type cases: the ORa for lifetime alcohol consumption over 507,499 g was 3.35 (95% CI: 0.81-13.88); and for more than 40 years of alcohol consumption it was 4.47 (95% CI: 1.05-19.02). Age at onset of alcohol consumption and years of abstinence were also associated with the presence of K-ras mutations. There were no significant differences in alcohol dependency. CONCLUSIONS Alcohol consumption is weakly associated with an increased risk of having a K-ras mutated PDA. To confirm or to refute the hypothesis that ethanol, acetaldehyde or other alcohol-related substances might influence the acquisition or persistence of K-ras mutations in the pancreatic epithelium, large and unselected studies are warranted.

Abstract
BACKGROUND/AIMS Ethanol consumption is associated with an increased risk of esophageal cancer. The carcinogenic compound is acetaldehyde, the product of ethanol metabolism. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are the main enzymes involved in ethanol metabolism, which leads to generation of acetaldehyde. In this study the activity of ADH isoenzymes and ALDH in esophageal cancer were compared with the activity in normal tissue. METHODS For measurement of the activity of class I and II ADH isoenzymes and ALDH activity fluorimetric methods were employed. Total ADH activity and activity of class III and IV isoenzymes was measured by the photometric method. Samples were taken from 59 esophageal cancer patients (27 adenocarcinoma, 32 squamous cell cancer). RESULTS The total activity of ADH and activity of class IV ADH were significantly higher in cancer cells than in healthy tissues. The other tested classes of ADH showed a tendency toward higher activity in cancer than in normal cells. Differences between the activity of enzymes of drinkers and non-drinkers in both cancer and healthy tissue were not significant. CONCLUSION Increased ADH IV activity may be a factor intensifying carcinogenesis, because of the increased ability to form acetaldehyde from ethanol.

Abstract
Although folic acid has been investigated for its potential to inhibit carcinogenesis, few epidemiologic studies have assessed the effects of intake of thiamin, riboflavin, and niacin, which may reduce cancer risk by acting as cofactors in folate metabolism or by other mechanisms. Using data from a large cohort of Canadian women, we examined the association of dietary intake of these nutrients, as well as intake of folate, methionine, and alcohol, with cancers of the breast, endometrium, ovary, colorectum, and lung ascertained during an average of 16.4 years of follow-up. After exclusions, the following numbers of incident cases were available for analysis: breast, n=2491; endometrium, n=426; ovary, n=264; colorectum, n=617; and lung, n=358. Cox proportional hazard models were used to estimate risk of each cancer with individual nutrients and to explore possible effect modification by combinations of nutrients on cancer risk. Few significant associations of intake of individual B vitamins with the five cancers were observed. Alcohol consumption showed a modest positive association with breast cancer risk but not with risk of the other cancers. There was no evidence of effect modification among the nutrients. This large study provides little support for an association of dietary intake thiamin, riboflavin, niacin, folate, or methionine with five major cancers in women.

Abstract
Previous studies reported the presence in rat mammary tissue of a cytosolic xanthine oxidoreductase pathway for the metabolism of alcohol to acetaldehyde and hydroxyl radicals and to the microsomal biotransformation of ethanol to acetaldehyde. It was also reported that after chronic ethanol drinking stressful oxidative conditions can be observed. The present work reports that even after single doses of ethanol, given at three different levels (6.3 g kg(-1); 3.8 g kg(-1) or 0.6 g kg(-1) p.o.), acetaldehyde accumulates for prolonged periods of time in the mammary tissue to reach concentrations higher than in blood (e.g. 5.1+/-1.2 nmol g(-1) versus 0.2+/-0.1 nmol ml(-1), for 6.3 g kg(-1) dose, 6 h after intoxication). The presence in rat mammary tissue of low activities of additional enzymes able to generate acetaldehyde was established (alcohol dehydrogenase: 0.97+/-0.84 mU mg(-1) protein; CYP2E1: 1.30+/-0.12 x 10(-2) pmol 4-nitrocatechol min(-1) mg(-1) protein) and a low activity of aldehyde dehydrogenase was observed in the cytosolic, mitochondrial and microsomal fractions (0.02+/-0.04; 0.35+/-0.09 and 0.72+/-0.19 mU mg(-1) protein, respectively). After a single high dose of ethanol, an increased susceptibility to oxidative stress was observed, as evidenced by changes in the shape of t-butylhydroperoxide induced emission of chemiluminescence in mammary tissue (6.3 g kg(-1) dose; at 3 and 6 h). In summary, the results show that even after single doses of ethanol, acetaldehyde, either formed in situ or arriving via blood, tends to accumulate in mammary tissue and that this condition might decrease cell defenses against injury.

Abstract
Many new and existing cases of viral hepatitis infections are related to injection drug use. Transmission of these infections can result directly from the use of injection equipment that is contaminated with blood containing the hepatitis B or C virus or through sexual contact with an infected individual. In the latter case, drug use can indirectly contribute to hepatitis transmission through the dis-inhibited at-risk behavior, that is, unprotected sex with an infected partner. Individuals who inject drugs are at-risk for infection from different hepatitis viruses, hepatitis A, B, or C. Those with chronic hepatitis B virus infection also face additional risk should they become co-infected with hepatitis D virus. Protection from the transmission of hepatitis viruses A and B is best achieved by vaccination. For those with a history of or who currently inject drugs, the medical management of viral hepatitis infection comprising screening, testing, counseling and providing care and treatment is evolving. Components of the medical management of hepatitis infection, for persons considering, initiating, or receiving pharmacologic therapy for opioid addiction include: testing for hepatitis B and C infections; education and counseling regarding at-risk behavior and hepatitis transmission, acute and chronic hepatitis infection, liver disease and its care and treatment; vaccination against hepatitis A and B infection; and integrative primary care as part of the comprehensive treatment approach for recovery from opioid abuse and dependence. In addition, participation in a peer support group as part of integrated medical care enhances treatment outcomes. Liver disease is highly prevalent in patient populations seeking recovery from opioid addiction or who are currently receiving pharmacotherapy for opioid addiction. Pharmacotherapy for opioid addiction is not a contraindication to evaluation, care, or treatment of liver disease due to hepatitis virus infection. Successful pharmacotherapy for opioid addiction stabilizes patients and improves patient compliance to care and treatment regimens as well as promotes good patient outcomes. Implementation and integration of effective hepatitis prevention programs, care programs, and treatment regimens in concert with the pharmacological therapy of opioid addiction can reduce the public health burdens of hepatitis and injection drug use.

Abstract
Genetic variations increasing blood levels of acetaldehyde, the first metabolite of alcohol, refrain their carriers from drinking alcohol but may also put them at increased risk of cancer because of the mutagenic and carcinogenic effect of acetaldehyde. In a population-based study of 305 cases and 428 controls in Warsaw, Poland, we evaluated the effect of polymorphisms in alcohol metabolizing genes, including ADH1B (Ex9+5C>T, Ex3+23A>G, Ex3+58A>T and Ex9+77A>G), ADH1C (Ex8-56A>G and Ex6-14G>A) and ALDH2 (Ex1+82A>G), on levels of alcohol drinking and susceptibility of stomach cancer. We found that among control subjects frequency of alcohol drinking varied by alcohol metabolizing genotype. In particular, the weekly consumption of individuals carrying the AA, GA and GG genotypes of ALDH2 Ex1+82A>G polymorphism were 3.75, 2.26 and 1.53 drinks, respectively (p=0.04). However, none of the assessed polymorphisms in these 3 genes had a measurable effect on stomach cancer risk. When stratified by ALDH2 Ex1+82A>G polymorphism, alcohol-related increases in stomach cancer risk were restricted to individuals with the AG/GG genotypes, with a more than 2-fold risk among daily drinkers (OR=2.63, 95% CI=1.00-6.88) and 3-fold risk (OR=3.66, 95% CI=1.19-11.24) among those with 40 or more drink-years. In summary, our results suggested that the ALDH2 Ex1+82 G allele may be functionally deficient in eliminating acetaldehyde and discourage alcohol drinking. Furthermore, heavy drinkers of alcohol who were genetically prone to accumulate acetaldehyde may face an increased risk of stomach cancer.

Abstract
The incidence of non-Hodgkin's lymphoma (NHL) has risen dramatically over recent decades and, despite some known risk factors, such as compromised immunity, the etiology of NHL and the reasons for most of this increase are unknown. Dietary components may be a common and critical source of immunologic antigens and promoters, which needs to be incorporated more in the etiologic research of NHL. To date, epidemiologic evidence suggests that obesity and fat intake, in particular saturated or animal fat, may increase the risk of NHL; whereas whole-grains, vegetables and moderate consumption of alcohol may be inversely associated with NHL risk. Much of the current evidence is obtained from case-control studies, which are subject to dietary recall bias; therefore, this area of research requires further study within prospective cohorts with detailed dietary information and with a large number of cases to examine disease sub-type heterogeneity.

Abstract
Chronic excessive alcohol consumption is the strongest risk factor for upper aerodigestive tract (UADT) cancer. Multiple mechanisms are involved in alcohol-associated cancer development of the UADT, including acetaldehyde (AA) effects. AA is toxic, mutagenic, and carcinogenic. Evidence of the role of AA in alcohol-associated carcinogenesis derived from genetic linkage studies in alcoholics. Polymorphism or mutation in genes coding for AA generation or detoxification enzymes are associated with increased cancer risk. It has been clearly shown in Asians that individuals carrying the acetaldehyde dehydrogenase 2*2 (ALDH2*2) allele have a significantly increased cancer risk when they consume alcohol. In Caucasians, alcohol dehydrogenase 1*1 (ADH1C*1) allele encodes for an alcohol dehydrogenase (ADH) isoenzyme, which produces 2.5 times more AA than the corresponding allele ADH1C*2. The authors found that the ADH1C*1 allele frequency and rate of homozygosity was significantly associated with an increased risk for alcohol-related cancer. AA seems to be an important factor in alcohol-associated carcinogenesis of the UADT.
