Journal of addictive diseases. 2016;(2):128-34
Abstract
This study is based on a drug prevention project for children in the German-Polish border region known as "Pomerania." The aim of this project was to minimize risk behaviors while developing social skills as protective factors through project-specific training interventions. The present study especially investigates the development of social skills and risk behaviors at German and Polish primary schools in the critical transitional period from primary to secondary school. Data on German 4th graders and Polish 6th graders were collected by means of a longitudinal and control group design through 3rd-party assessment from teachers. The data on social skills was collected through the use of standardized assessment instruments. The study established that social skills could indeed be increased through training and that risk behaviors decreased in both of the treatment groups. The control group showed altogether an increase in risk behavior and a decrease in coping skills. In the Polish treatment group, even risk behaviors which had been detected previously decreased. The German control group showed an increase in risk behaviors and a decrease in coping skills. In the case of the younger German pupils, the effectiveness of the interventions was exhibited indirectly. Despite variations in age and cultural differences, the effects of training were noticeable in children from both countries. The intervention program offered the children adequate assistance in order to successfully cope with this stressful life event. It promoted the development of social skills while minimizing risk behaviors.

Skin pharmacology and physiology. 2013;(1):45-51
Abstract
In recent years, epidemiological data has demonstrated that alcohol consumption is a risk factor for sunburn, melanoma and nonmelanoma skin cancer. We hypothesized that if the concentration of the antioxidants in the skin has already decreased due to alcohol consumption, then an adequate neutralization of the free radicals induced by ultraviolet light cannot be performed. Based on this hypothesis, we determined the carotenoid concentration in the skin and the minimal erythema dose (MED) of 6 male human volunteers before and after consumption of alcohol or alcohol and orange juice combined. The results showed a significant decrease in the carotenoid concentration in the skin and the MED after alcohol consumption, but no significant decrease after a combined intake of alcohol and orange juice.

Nutrition, metabolism, and cardiovascular diseases : NMCD. 2008;(5):365-72
Abstract
BACKGROUND AND AIMS To analyse the association of moderate beer consumption on the blood lipid profile in healthy Spanish adults. METHODS AND RESULTS The study had an intervention longitudinal design in which each subject established their own control with a previous wash-out phase. After a 30-day alcohol abstinence period, 57 healthy volunteers were submitted to a daily moderate intake of beer for 30 days. Serum total cholesterol, HDL-cholesterol, triacylglycerols, GOT, GPT, GGT and glucose values, as well as blood erythrocytes, haemoglobin, haematocrit and MCV levels, together with anthropometric parameters were determined at the beginning of the study (baseline levels) (a), after 1 month of alcoholic abstinence (b) and after 1 month of moderate beer consumption (c). Dietary intake was assessed twice by a 7-day dietary record. HDL-cholesterol, erythrocytes, haematocrit and MCV levels increased significantly (p<0.05) after moderate beer consumption in women. In men, a decrease in HDL-cholesterol levels was observed after alcohol abstention. Haematocrit and MCV counts also increased significantly (p<0.05) in men after moderate beer consumption. There were no dietary changes during the study. CONCLUSION In healthy Spanish adults, the effects of moderate beer consumption during 1 month were associated with favourable changes on the blood lipid profile.

Pharmacological research. 2002;(1):47-50
Abstract
Blood lead levels (PbB), delta-ALA dehydratase activity (ALAD) and erythrocytic protoporphyrin (EPP) values were studied in heavy wine and spirit drinkers. Results were compared in both groups and with a control group (teetotalers). Results in all cases are expressed as arithmetic means +/- SD. PbB values found in the three groups were statistically different inter se: wine group, 195 +/- 82 microg l(-1); spirits group, 159 +/- 69 microg l(-1); teetotalers, 72 +/- 43 microg l(-1). ALAD was significantly lower in the drinker groups (wine 26.9 plus minus 11.4 U l(-1)and spirits 28.3 plus minus 11.6 U l(-1))vs the control group (48.3 plus minus 13.5 U l(-1)). Differences in EPP levels in the three groups were only significant between the teetotaler and the wine drinker groups. Our findings indicate that, in heavy drinkers (more than 2 liters of wine per day), not only are lead levels increased in the blood but there are also biochemical alterations that affect the heme biosynthetic pathway, which should be taken into account in treatment for alcoholics.

Journal of hepatology. 2002;(1):47-52
Abstract
BACKGROUND/AIMS: Chronic ethanol consumption results in the induction of hepatic cytochrome P4502E1 (CYP2E1) in man, which is believed to play an important role in the pathogenesis of alcoholic liver disease. However, the amount and duration of alcohol intake associated with CYP2E1 induction is not known but limited information is available on the disappearance of CYP2E1 following alcohol withdrawal. METHODS To study these questions, five healthy male volunteers received ethanol daily (40 g/day) over 4 weeks. CYP2E1 induction was monitored by using the chlorzoxazone test before and every week following the start of alcohol ingestion. In addition, CYP2E1 was also determined in five alcoholics 1, 3, 8 and 15 days following ethanol withdrawal and in five patients with non-alcoholic liver disease. RESULTS A significant CYP2E1 induction occurred 1 week following the ingestion of 40 g ethanol per day and increased further after 4 weeks. The disappearance of CYP2E1 was found to be significant 3 days following ethanol withdrawal and further decreased up to day 8. Thereafter, no significant change occurred and CYP2E1 activities were comparable with those in patients with non-alcoholic liver disease. CONCLUSIONS These data show a significant and quick induction of CYP2E1 activity, already at moderate alcohol consumption, which may be of importance in the pathogenesis of alcoholic liver disease, of ethanol, drug and vitamin A interactions and in alcohol associated carcinogenesis.

Effect of moderate alcohol consumption on fibrinogen levels in healthy volunteers is discordant with effects on C-reactive protein.
Sierksma, A, van der Gaag, MS, Kluft, C, Hendriks, HF
Annals of the New York Academy of Sciences. 2001;:630-3
Abstract
In a diet-controlled, crossover trial with 10 middle-aged men and 9 postmenopausal women, baseline concentrations of fibrinogen influenced the magnitude of decrease of fibrinogen after moderate alcohol consumption. The mechanism of reduction is specific for fibrinogen and unrelated to a reduction in C-reactive protein.

Abstract
Although chewing tobacco, smoking, and alcohol drinking have been suggested as risk factors for oral cancer, no study has examined the relationship between those factors and the risk of erythroplakia, an uncommon but severe oral premalignant lesion. In this study, we have analyzed the effects of chewing tobacco, smoking, alcohol drinking, body mass index, and vegetable, fruit, and vitamin/iron intake on the risk of erythroplakia and explored potential interactions between those factors in an Indian population. A case-control study including 100 erythroplakia cases and 47,773 controls was conducted, as part of an on-going randomized oral cancer screening trial in Kerala, India. The analysis was based on the data from the baseline screening for the intervention group, where the diagnostic information was available. The information on epidemiological risk factors was collected with interviews conducted by trained health workers. The erythroplakia cases were identified by health workers with oral visual inspections, and then confirmed by dentists and oncologists who made the final diagnosis. The odds ratios (OR) and their 95% confidence intervals (CIs) were calculated by the logistic regression model using SAS software. The adjusted OR for erythroplakia was 19.8 (95% CI, 9.8-40.0) for individuals who had ever chewed tobacco, after controlling for age, sex, education, body mass index, smoking, and drinking. The adjusted OR for ever-alcohol-drinkers was 3.0 (95% CI, 1.6-5.7) after controlling for age, sex, education, body mass index, chewing tobacco, and smoking. For ever-smokers, the adjusted OR was 1.6 (95% CI, 0.9-2.9). A more than additive interaction on the risk of erythroplakia was suggested between tobacco chewing and low vegetable intake, whereas a more than multiplicative interaction was indicated between alcohol drinking and low vegetable intake, and between drinking and low fruit intake. We concluded that tobacco chewing and alcohol drinking are strong risk factors for erythroplakia in the Indian population. Because the CIs of interaction terms were wide and overlapping with those of the main effects, only potential interactions are suggested.

Cancer causes & control : CCC. 2000;(3):239-47
Abstract
OBJECTIVES To study the association between alcohol consumption and breast cancer risk. METHODS A case-cohort analysis was undertaken within the cohort of 56,837 women who were enrolled in the Canadian National Breast Screening Study (NBSS) and who completed a self-administered dietary questionnaire. (The NBSS is a randomized controlled trial of screening for breast cancer in women aged 40-59 at recruitment.) The cohort was recruited between 1980 and 1985, and during follow-up to the end of 1993 a total of 1469 women in the dietary cohort were diagnosed with biopsy-confirmed incident breast cancer. For comparative purposes a subcohort consisting of a random sample of 5681 women was selected from the full dietary cohort. After exclusions for various reasons the analyses were based on 1336 cases and 5238 noncases. RESULTS When compared to nondrinkers the adjusted incidence rate ratios (95% confidence intervals) for those consuming > 0 and < or = 10 g of alcohol/day, > 10 and < or = 20 g/day, > 20 and < or = 30 g/day, > 30 and < or = 40 g/day, > 40 and < or = 50 g/day, and > 50 g/day were 1.01 (0.84-1.22), 1.16 (0.91-1.47), 1.27 (0.91-1.78), 0.77 (0.51-1.16), 1.00 (0.57-1.75), and 1.70 (0.97-2.98), respectively; the associated p value for the test for trend was 0.351. Similar findings were obtained when analyses were conducted separately in the screened and control arms of the NBSS, in premenopausal and postmenopausal women, for screen-detected and interval-detected breast cancer, and by levels of other breast cancer risk factors. CONCLUSIONS The results of this study suggest that alcohol consumption might be associated with increased risk of breast cancer at relatively high levels of intake.
