Abstract
Lockdowns to contain the spread of the SARS-CoV-2 have disrupted routines and behaviors, which could lead to a worsening of lifestyle and an increase in the burden of non-communicable diseases. This study aimed to describe the changes in physical activity, diet, alcohol drinking, and cigarette smoking during lockdown. A self-administered online survey addressing adults living in a province in northern Italy was advertised through websites and social media. Citizens could access the survey in anonymity from 4 May until 15 June 2020. A total of 1826 adults completed the survey, with a worsening of physical activity (35.1%), diet (17.6%), alcohol drinking (12.5%), and cigarette smoking (7.7%) reported. In contrast, 33.5% reported an improvement in diet, 12.6% in alcohol drinking, 5.3% in physical activity and 4.1% in cigarette smoking. Female sex, young adult age, suspension of work activity, and symptoms of psychological distress were the factors associated with a greater likelihood of change, which was frequently for the worse. Lockdown had an impact on lifestyle, with some net beneficial effects on diet and mostly negative effects on physical activity. Public health measures should be implemented to avoid long-term negative effects of the lockdown, supporting individuals more prone to change for the worse.

Abstract
High adolescent alcohol consumption is predictive for alcohol problems later in life. To tailor interventions, early identification of risk groups for adolescent alcohol consumption is important. The IMAGEN dataset was utilized to investigate predictors for problematic alcohol consumption at age 18-20 years as a function self and parental personality and drug-related measures as well as life-events and cognitive variables all assessed at age 14 years (N = 1404). For this purpose the binary partitioning algorithm ctree was used in an explorative analysis. The algorithm recursively selects significant input variables and splits the outcome variable based on these, yielding a conditional inference tree. Four significant split variables, namely Place of residence, the Disorganization subscale of the Temperament and Character Inventory, Sex, and the Sexuality subscale of the life-events questionnaire were found to distinguish between adolescents scoring high or low on the Alcohol Use Disorders Identification Test about five years later (all p < 0.001). The analyis adds to the literature on predictors of adolescent drinking problems using a large European sample. The identified split variables could easily be collected in community samples. If their validity is proven in independent samples, they could facilitate intervention studies in the field of adolescent alcohol prevention.

Abstract
BACKGROUND Red blood cell (RBC) storage in the blood bank is associated with the progressive accumulation of oxidant stress. While the mature erythrocyte is well equipped to cope with such stress, recreative habits like alcohol consumption may further exacerbate the basal level of oxidant stress and contribute to the progress of the storage lesion. STUDY DESIGN AND METHODS RBC levels of ethyl glucuronide, a marker of alcohol consumption, were measured via ultra-high-pressure liquid chromatography coupled with high-resolution mass spectrometry. Analyses were performed on 599 samples from the recalled donor population at Storage Days 10, 23, and 42 (n = 250), as part of the REDS-III RBC-Omics (Recipient Epidemiology Donor Evaluation Study III Red Blood Cell-Omics) study. This cohort consisted of the 5th and 95th percentile of donors with extreme hemolytic propensity out of the original cohort of 13,403 subjects enrolled in the REDS-III RBC Omics study. Ehtyl glucuronide levels were thus correlated to global metabolomics and lipidomics analyses and RBC hemolytic propensity. RESULTS Ethyl glucuronide levels were positively associated with oxidant stress markers, including glutathione consumption and turnover, methionine oxidation, S-adenosylhomocysteine accumulation, purine oxidation, and transamination markers. Decreases in glycolysis and energy metabolism, the pentose phosphate pathway and ascorbate system were observed in those subjects with the highest levels of ethyl glucuronide, though hemolysis values were comparable between groups. CONCLUSION Though preliminary, this study is suggestive that markers of alcohol consumption are associated with increases in oxidant stress and decreases in energy metabolism with no significant impact on hemolytic parameters in stored RBCs from healthy donor volunteers.

BMC public health. 2018;(1):1281
Abstract
BACKGROUND The consumption of alcohol and other drugs causes social and health problems in industrialized societies. Furthermore, alcohol and drug consumption in the workplace is associated with work accidents, absenteeism and low productivity. The aim of the current study is to reduce alcohol and drug consumption among workers in the service industry and, as a secondary aim, to improve their healthy habits through the reduction of alcohol and other drug consumption in their leisure time. METHODS This nonrandomized, single-group study was conducted in 12 work centers. The intervention began in 2009 and emphasized 1) health promotion and health monitoring, which included a) alcohol and drug awareness and b) the evaluation and monitoring of alcohol and drug consumption through a semistructured interview designed to assess risky consumption; urine tests aimed at detecting alcohol, cannabis and cocaine use; an Alcotest based on expired air to test for the recent consumption of alcohol and a saliva exam to test for the recent consumption of six drugs; and 2) secondary prevention if risky consumption was identified. Risky alcohol consumption was defined as the ingestion of more than 28 standard drink units (SDUs)/week among men and more than 17 SDUs/week among women (taking into account both work and leisure time). Drug consumption was considered risky consumption. RESULTS A total of 1103 workers participated, and each received 5 h of awareness training. Those who presented with risky consumption received secondary prevention training. The prevalence of risky alcohol consumption decreased by 4.1% (baseline: 14.7% reduced to 10.6% in the first year; p = 0.001), a reduction that was maintained over a 3-year follow-up period. CONCLUSION A comprehensive program of worker health surveillance that involves stakeholders and includes monitoring can be a means of potentially improving compliance with workplace promotion programs, resulting in the facilitation of such beneficial, desired behavior change in areas such as alcohol and drug consumption.

International journal of sport nutrition and exercise metabolism. 2017;(2):115-121
Abstract
This study was designed to investigate the effects of alcohol consumption on recovery of muscle force when consumed immediately postexercise in young females. Eight young women completed 300 maximal eccentric actions of the quadriceps femoris muscle on an isokinetic dynamometer on two occasions in a randomized, cross-over design after which an alcoholic beverage (0.88g ethanol/kg body weight) or an iso-caloric placebo was consumed. Maximal isokinetic (concentric and eccentric) torque and isometric tension produced across the knee were measured in both the exercised and control leg predamage, 36 hr post, and 60 hr post damage. Venous blood creatine kinase (CK) activity and muscle soreness ratings were taken before damage and once per day to 60 hr post damage. Significant differences were observed between the exercised and control leg for maximal concentric, and eccentric torque and isometric tension (p < .05). A near significant Treatment × Time interaction was observed for isometric tension (p = .077), but not for concentric or eccentric torque. No main effects of treatment (alcohol) or interactions with Time × Leg or Leg × Treatment were observed. Perceived muscle soreness during box stepping and squatting showed significant time effects (p < .05), and CK activity did not significantly change. Our results indicate that the consumption of 0.88g ethanol/kg body weight following eccentric exercise-induced muscle damage does not affect recovery in the days following damage in females.

Abstract
BACKGROUND Congenital anomalies of the kidney and urinary tract (CAKUT) comprise a heterogeneous group of birth defects with a variety of genetic and nongenetic factors suspected of involvement in the etiology. However, little is known about risk factors in specific CAKUT phenotypes. Therefore, we studied potential maternal risk factors in individual phenotypes within the CAKUT spectrum. METHODS Questionnaire data were collected from parents of 562 children with CAKUT and 2139 healthy controls within the AGORA data- and biobank. Potential maternal risk factors investigated included folic acid use, overweight and obesity, smoking, alcohol consumption, subfertility, and diabetes mellitus. We performed logistic regression analyses to assess associations between these potential risk factors and CAKUT phenotypes. RESULTS Increased risks of CAKUT were observed for folic acid use and maternal obesity, while fertility treatment by in vitro fertilization or intrauterine insemination and diabetes diagnosed during pregnancy also seem to be associated with CAKUT. Use of multivitamins reduced the risk (odds ratio [OR], 0.5; 95% confidence interval [CI], 0.2-1.0) as opposed to use of folic acid supplements only (OR, 1.3; 95% CI, 1.0-1.8). Folic acid use was associated with duplex collecting systems (OR, 1.8; 95% CI, 1.0-3.4) and vesicoureteral reflux (OR, 1.8; 95% CI, 1.1-2.9) in particular. A relatively strong association was observed between diabetes during pregnancy and posterior urethral valves (OR, 2.6; 95% CI, 1.1-5.9). CONCLUSION Use of folic acid only seems to be counterproductive for prevention of CAKUT, in contrast to multivitamin use. Furthermore, we observed differences in risk factor patterns among CAKUT phenotypes, which stress the importance of separate analyses for each phenotype.

Abstract
BACKGROUND & AIMS Some patients develop multiple squamous cell carcinomas (SCCs) in the upper aerodigestive tract, attributed to field cancerization; alcohol consumption has been associated with this process. We examined the association between multiple areas of dysplastic squamous epithelium with the development of SCC of the esophagus or head and neck cancer, as well as alcohol consumption and smoking. METHODS We examined 331 patients with early stage esophageal SCC using Lugol chromoendoscopy to evaluate the dysplastic squamous epithelium in the esophagus. Patients then were assigned to 3 groups, based on the number of Lugol-voiding lesions: A, no lesion; B, 1-9 lesions; or C, 10 or more lesions. Participants completed lifestyle surveys on their history of drinking, smoking, and diet. All participants were evaluated by laryngopharyngoscopy before registration; only those without head and neck cancer were included, except for patients with superficial SCC limited to the subepithelial layer. Lesions detected in the esophagus and head and neck by surveillance were considered to be metachronous. The study end point was the cumulative incidence of metachronous SCCs in the esophagus and head and neck after endoscopic resection of esophageal SCC, according to the grade of Lugol-voiding lesions. At study entry, all patients were instructed to abstain from alcohol and smoking. RESULTS Over the 2-year study period, metachronous SCCs of the esophagus were detected in 4% of patients in group A, in 9.4% of patients in group B, and in 24.7% of patients in group C (P < .0001 for patients in group A vs B or B vs C). Head and neck SCCs were detected in none of the patients in group A, in 1.7% of the patients in group B, and in 8.6% of the patients in group C (P = .016 for patients in group A vs C and P = .008 for patients in group B vs C). SCC of the esophagus or head and neck developed in 4.0% of patients in group A, in 10.0% of patients in group B, and in 31.4% of patients in group C (P < .0001 for group A vs B or A vs C). Alcohol abstinence decreased the risk of multiple SCCs of the esophagus (adjusted hazard ratio, 0.47, 95% confidence interval, 0.25-0.91; P = .025), whereas smoking abstinence did not. CONCLUSIONS Multiple dysplastic lesions in the esophagus increase the risk of multiple SCCs. Alcohol abstinence reduces the risk of metachronous SCCs.

Moderate alcohol consumption in chronic form enhances the synthesis of cholesterol and C-21 steroid hormones, while treatment with Tinospora cordifolia modulate these events in men.
Kumari, S, Mittal, A, Dabur, R
Steroids. 2016;:68-77
Abstract
Chronic and heavy alcohol consumption disrupts lipid metabolism and hormonal balance including testosterone levels. However, studies doubt the relationship between moderate alcohol intake and sex hormone levels. Therefore, the aim of the present investigation was to establish the direct impact of chronic and moderate alcohol intake on cholesterol homeostasis and steroid hormone synthesis. Asymptomatic chronic and moderate alcoholics (n=12) without chronic liver disease and healthy volunteers (n=14) were selected for the study. Furthermore, effects of standardized water extract of Tinospora cordifolia (Willd) Mier. (Menispermaceae) (TCJ), a well reported anti-alcoholic herbal drug, on urinary steroids was studied. This study included four groups, i.e. a) healthy; b) healthy+TCJ; c) alcoholic; d) alcoholic+TCJ. The blood and urine samples from each group were collected on day 0 and 14 of the post-treatment with TCJ and analyzed. Alcoholic blood samples showed the significantly higher values of traditional biomarkers γ-GT and MCV along with cholesterol, LDL, TGL and urinary methylglucuronide compared to healthy. Qualitative analysis of steroids showed that moderate alcohol intake in a chronic manner increased the cholesterol synthesis and directed its flow toward C-21 steroids; shown by increased levels of corticosterone (2.456 fold) and cortisol (3.7 fold). Moreover, alcohol intake also increased the synthesis of estradiol and clearance rate of other steroids through the formation of glucuronides. Therefore, it decreased the synthesis and increased the clearance rate of testosterone (T) and androstenedione (A). Quantitative analysis confirmed decreased T/A ratio from 2.31 to 1.59 in plasma and 2.47 to 1.51 in urine samples of alcoholics. TCJ intervention normalized the levels of steroids and significantly improved the T:A ratio to 2.0 and 2.12 in plasma and urine. The study revealed that TCJ modulated lipid metabolism by inhibiting cholesterol and glucuronides synthesis.

Magma (New York, N.Y.). 2015;(5):503-10
Abstract
OBJECTIVE It has previously been reported that even social alcohol consumption affects the magnetic resonance spectroscopy (MRS) signals of choline-containing compounds (tCho). The purpose of this study was to investigate whether the consumption of alcohol affects the concentrations of the metabolites tCho, N-acetylaspartate, creatine, or myo-inositol and/or their T 2 relaxation times. MATERIALS AND METHODS (1)H MR spectra were obtained at 3 T from a frontal white matter voxel of 25 healthy subjects with social alcohol consumption (between 0 and 25.9 g/day). Absolute brain metabolite concentrations and T 2 relaxation times of metabolites were examined via MRS measurements at different echo times. Metabolite concentrations and their T 2 relaxation times were correlated with subjects' alcohol consumption, controlling for age. RESULTS We observed positive correlations of absolute tCho and phosphocreatine and creatine (tCr) concentrations with alcohol consumption but no correlation between any metabolite T 2 relaxation time and alcohol consumption. CONCLUSIONS This study shows that even social alcohol consumption affects the concentrations of tCho and tCr in cerebral white matter. Future studies assessing brain tCho and tCr levels should control for the confounding factor alcohol consumption.

Journal of medicinal food. 2015;(2):166-72
Abstract
Alcohol induces oxidative stress and inflammatory response, which can lead to hepatitis and cirrhosis. Previous studies reported that the extracts of Angelica keiskei Koidzumi (AKE) have antioxidant and anti-inflammatory properties, suggesting that AKE could improve abnormalities associated with alcoholic liver disease. In this study, the effectiveness of AKE supplementation was assessed in 82 habitual alcohol drinkers (male: more than 14 units per week, female: more than 7 units per week) with abnormal liver biochemistry in a placebo-controlled, randomized double-blind trial over 12 weeks. Among the subjects, 65% (n=43) were heavy drinkers consuming more than 35 units per week. Among heavy drinkers, gamma-glutamyl transferase levels of 19 subjects per AKE-treated group were significantly decreased (21.16±37.63, P=.016) with significant differences observed compared to the 24 subjects per placebo group (P=.046). However, no significant differences were observed in aspartate aminotransferase and alanine aminotransferase levels between the AKE- and placebo-treated groups. These results suggest that AKE supplementation might improve liver function in heavy drinkers.
